12 --- 5.14.11 2015/10/09
14 Fix RPN to CQL rejects local Bib-1 attribute set YAZ-861
16 ZOOM C: tweak when connection failed is returned
17 For cases with multiple socket addresses for some hostname, eg
18 localhost IPV4+IPV6, the code now properly returns "connection
19 failed" rather than "connection lost".
21 Various minor documenation tweaks from David Crossley. Thanks.
23 Fix windows uninstall does not remove start menu shortcuts YAZ-860
25 --- 5.14.10 2015/09/16
27 Prevent huge expansions in CCL s=sl YAZ-859
31 Fix segv in ZOOM_connection_fire_event_socket YAZ-858
32 The odr_in memory taken by handle_srw_response, and, thus if result
33 set is destructed before we expect the HTTP response (hres) it may
34 be come invalid. Therefore we inspect hres before the call to
37 Fix possible deadlock in backtrace (2nd attempt) YAZ-856
38 An alarm is set up so that backtrace is terminated if it hangs.
39 Even if backtrace the handler also attempts to spawn gdb.
43 Fix SEGV for s=sl for 3 terms and syntax error YAZ-857
47 Fix possible deadlock in backtrace YAZ-856
49 Various minor text tweaks in documentation
53 Fix yaz-client command args parsing broken YAZ-855

71 Omit Content-Type for HTTP requests to Solr YAZ-850
75 Fix rpn2cql: structure, relation problem for serverChoice YAZ-849
76 Problem was that for things mapped to cql.serverChoice the relation
77 would sometimes be omitted when it should not. Eg for relation "all".
81 Document zoom extraArgs YAZ-817
83 Fix ZOOM: crash extended services diagnostics YAZ-846
84 The immediate fix is to prevent ZOOM_set_dset_error from removing
85 current task from connection. This, however, has been assumed in a
86 number of places so this fix is rather large unfortunately.
90 Make yaz_log_reopen async-signal YAZ-845
91 Fixes potential dead-lock issue with YAZ_DAEMON_LOG_REOPEN flags for
96 CCL: new feature s=spl (split-list) that splits terms in a search into
97 sub-phrases of all sizes (from 1 up to the number of terms) with order
98 preserved. For 3 terms the CCL search
101 @or @or @or @and @and a b c @and "a b" c @and a "b c" "a b c"
103 Solr: don't set defType=lucene in URLs if extraArgs already defines it.

133 --- 5.11.0 2015/03/31
135 Extend get_org_info (snippets) to return original string YAZ-836
136 Two new functions have appeared: icu_chain_get_org_info2 and
137 icu_iter_get_org_info2 with a 4th parameter being a pointer
138 to the original string.
140 Fix tcpip.c compilation failure on VC9 YAZ-835
142 Fix icu_iter_get_norm returns invalid size for some input YAZ-834
143 The icu_iter_get_org_info returns information based on string
144 as it appears on tokenize step.
146 --- 5.10.2 2015/03/13
148 Deal with excess bytes in HTTP response for keepalive YAZ-830

156 Fix buffer overflow in cmd_elements in yaz-client YAZ-828
158 --- 5.10.1 2015/03/03
160 Fix test_sru.sh fails in pazpar2 YAZ-826
161 Unfortunately a regression occurred with YAZ 5.10.0 that would make
162 Pazpar2 fail for HTTP connections.
164 --- 5.10.0 2015/03/03
166 Use CONNECT for SSL backends and for Z39.50 thru HTTP proxy YAZ-825
167 Introduce cs_create_host2 which returns if connection should be
168 proxy aware (HTTP:absoluteUri or Z39.50 proxy:vhost in init).. For CONNECT,
169 the connection is NOT proxy aware (no absoluteUri and no Z39.50 vhost).
171 Fix http proxy fails with yaz-client YAZ-824
175 Fix 0 ptr reference for OPAC records from XML YAZ-822
179 Extend yaz daemon facility to assist int log rotation YAZ-818 YAZ-819

185 retrieval: pick matched element-set rule YAZ-813
187 Fix crash in record conv rule 'select' YAZ-812
191 record_conv: selection by X-Path YAZ-811
192 That's a new step in record conversion system (<select path=".."/>)
194 Document record render parameters for ZOOM - including base64
198 Fix application/x-www-form-urlencoded + empty YAZ-810
199 A SEGV occurred if Content-Type was "application/x-www-form-urlencoded"
200 and empty content was supplied.
202 Fix yaz-iconv man page for typos and incorrect example. YAZ-809
204 Fail hard if Bison is not found and is needed YAZ-808
208 Enable YAZ backtrace for programs YAZ-802
210 Update NMAKE makefile to use Visual Studio 2013 along with ICU 54.1,
211 Libxml2 2.9.2, Libxslt 1.1.28.
213 Fix daemon: parent process stops before child YAZ-806
214 Try to fix the situation where parent process stops before
215 child has acknowledged it .. SIGUSR2 back!
217 daemon: log message when keepalive stops.
221 Fix yaz-marcdump segfault YAZ-801. Problem in YAZ 5.6.0/5.7.0 and
222 would make yaz-marcdump crash when from-character set was issued.
226 Dump backtrace in case of SIGABRT, SIGSEGV YAZ-787
227 New function yaz_enable_panic_backtrace which enables backtrace
228 handler for current process. The handler will call backtrace always,
229 then gdb to provide as much detail as possible.
233 When marc-8 charset is specified when decoding MARC records, yaz-marcdump
234 and ZOOM record render will inspect leader 9 and switch to UTF-8
235 (Unicode) if that holds 'a'. This changes behavior, but is considered
236 safe because only MARC21 with leader 9='a' are Unicode. YAZ-800
238 Fix cs_put may reconnect if send fails. YAZ-798
242 Fix cannot build YAZ on jessie : libgnutls-dev is gone YAZ-797
246 Extended comstack with outgoing IP YAZ-795.
247 For cs_create_host + cs_create_host_proxy the vhost may be followed
248 by a outgoing host/IP. Separator is blank.
252 Add YAZ_EXPORT to cql_transform_r fixes YAZ-793 . This issue fixes
253 linker error with yazpp on Windows.
257 Fix uri array may overflow in yaz_solr_encode_request YAZ-775
259 Fix PQF to Solr conversion may produce invalid Solr query YAZ-792
261 0 ptr reference in handling Solr response with error YAZ-791
263 Fix annoying warning about wrbuf_putc on newer GCC YAZ-789
265 Fix documentation about --installa option YAZ-788
269 daemon: properly report when receiving SIGUSR2 from child YAZ-785
273 xmalloc: throw assert for clearly invalid calls to malloc and
274 improve diagnostics YAZ-783 YAZ-784
278 Stop building debs for Ubuntu raring, quantal, oneiric.
280 CCL YAZ-781: for multiple use attributes in a specification the
281 generated RPN will perform @or on each term.
282 For spec: term u=31 u=1016
283 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
285 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
287 CCL YAZ-779: combo qualifier should allow for forward references
289 Fix buildconf.sh, automake too old on centos5 YAZ-778
290 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
291 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
292 accepts it without a warning.
296 GFS: client_query_charset conversion YAZ-777
297 This is a feature for Z39.50 clients that sends queries that are not
298 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
299 encoding given to UTF-8.
301 Echoed SRU arguments support YAZ-776
302 This is achieved with new function yaz_srw_get_pdu_e.
304 ZOOM: expire times set for redis/memcached YAZ-772
305 For both redis and memcached option --expire=seconds sets expire
306 time for a result-set/search. Default time is 600 seconds (10 minutes).
310 No [rest of output is omitted] limit for yaz_log YAZ-774
312 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
314 For ICU testing, pass -o to yaz-icu. This will test the
315 icu_iter_get_org_info function.
317 Fix null ptr reference for freeReplyObject YAZ-773
321 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
323 RPM: do not build with libmemcached support. The libmemcached library
324 on CentOS 5/6 does not work reliably for us (redis to the rescue).
326 configure: only allow libmemcached version 0.40 or later. That's the version
327 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
328 that's not an option, consider redis.
332 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
334 Fix zoom+memcached: present request out of range YAZ-767
338 CCL: add new qualifier r=omiteq which will omit relation=equals
339 for ordered relations. This should be used in combination with either
342 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
344 Solr: simplify yaz_solr_decode_response
346 Solr: use different local var for string manipulation
348 Solr: Get rid of hardcoded limit of extra_args
350 Solr: encode lucene query type YAZ-736
351 Make sure the queries are treated as traditional "lucene", because that's
354 Fix ZOOM HTTP redirect failing on Windows+Solaris YAZ-755
358 Build packages for Ubuntu Trusty Tahr 14.04 LTS
360 wrbuf_cstr: fix off by one error.
362 wrbuf_buf: make it always return non-NULL
363 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
367 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
369 zoomsh: offer option -a apdulog
370 As we're used to from yaz-client and GFS based servers.
372 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
373 existing setting apdulog takes effect.
375 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
380 Add re-entrant CQL/Solr/RPN query conversion functions.
381 The re-entrant functions are: cql_transform_r,
382 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
383 These have same functionality as cql_transform,
384 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
385 return the additional infomration as WRBUF to make them re-entrant.
387 Remove CQL to Solr conversion and base solr_transform_t on
388 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
389 data structure as cql_transform_t.
391 cql2pqf utility allows RPN to Solr conversion
393 Fix assert in ZOOM when http connect fails YAZ-757
395 --- 5.0.22 2014/04/09
397 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
399 wrbuf_cstr: make it thread safe YAZ-753
401 yaz_log_init_file may take fd=<no> to open log file at the FD given.
403 --- 5.0.21 2014/03/21
405 Offer new utility function zget_AttributeList_use_string.
407 New conversion step, solrmarc, for record conversion module.
409 --- 5.0.20 2014/03/13
411 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
412 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
415 --- 5.0.19 2014/03/10
417 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
418 The standalone ZOOM sort was completely broken since 5.0.13.
420 ZOOM: generate event Connect rather than None for partial connect
421 (in fact getaddrinfo resolving).
423 ZOOM: only supply clientIP for InitRequest. Rather than for all
426 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
428 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
429 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
430 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
432 New "Facets" section in the documentation.
434 --- 5.0.18 2014/02/27
436 Call exsltRegisterAll in yaz_init_globals, so that all applications
437 using YAZ will have EXSLT things enabled.
439 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
441 Update various URLs to the re-organized SRU pages at LoC.
443 --- 5.0.17 2014/02/26
445 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
446 introduced in 5.0.12.
448 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
449 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
450 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
453 --- 5.0.16 2014/02/25
455 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
457 --- 5.0.15 2014/02/24
459 Fix gcrypt not properly initialized YAZ-740.
461 --- 5.0.14 2014/02/19
463 Describe memcached option for ZOOM.
465 ZOOM: throw present request out of range again YAZ-739
466 Was removed in YAZ 5.0.13.
468 --- 5.0.13 2014/02/18
470 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
471 with localtime_r when threads + fork is used (such as Metaproxy).
473 yaz-config: quote some RHS values (that might include blanks)
475 zoomsh: shows SearchResult-1
477 zoomsh: sortby command
479 zoomsh: use proper list of connections and result sets YAZ-725
481 Avoid yaz_log in sigterm handler for GFS YAZ-737
482 Logging is still performed, but outside sig handler.
484 New ZOOM C feature: result-set caching with memcached. Example:
485 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
487 Remove SSL via OpenSSL support YAZ-732
488 Also deprecate two functions from comstack that aren't working with
489 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
491 Revert "Bison: use %name-prefix directive rather than -p option"
493 --- 5.0.12 2014/01/22
495 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
497 SRU GET/Solr base URLs may hold additional ?args YAZ-729
498 ZOOM option extraArgs already does this, though. It seems useful
499 when dealing with Solr targets to limit by filter, eg.
500 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
502 Remove #fragment for HTTP request encoding YAZ-730
504 Doc: Update list of DLLs/LIBs
506 Doc: update href link to Unix utils and Git.
508 --- 5.0.11 2014/01/15
510 ZOOM: fix "lost connection" problem with servers that uses both squid
511 and another proxy behind it that returns Location headers with relative
514 zoomsh: do not use readline for stdin (no tty) YAZ-724
515 Just use fgets in that case. If the user hits Ctrl-D a new-line
518 zoomsh: empty command ignored YAZ-723
519 rather than performing exit of zoomsh.
521 yaz-url utility offers option -v to enable verbose mode.
523 yaz_url uses yaz_check_location and offers verbose mode.
525 Add new function yaz_check_location.
526 This function gets an absolute URI from Location (HTTP redirect).
528 cookie API: introduce yaz_cookies_reset
530 Update cql.y for newer bison YAZ-720
531 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
532 longer supported. Instead one must use %lex-param and %parse-param .
534 --- 5.0.10 2014/01/09
536 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
539 rpn2solr: support truncation left(2), left&right(3) YAZ-718
541 Mention SRU version 2.0 in yaz-client man page.
545 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
550 Make cs_parse_host public.A
552 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
553 introduced in YAZ 5.0.6.
557 Fix buffer corruption for yaz-ztest record fetch.
561 Allow yaz-ztest to return user-defined records (one record per file).
562 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
564 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
565 Use the stream write instead of odr_printf which has a 4K tmp buffer.
567 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
571 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
572 can read and write this format. For record format JSON, yaz-ztest returns
573 MARC-in-JSON records.
575 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
576 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
580 Improve error reporting for ICU chains YAZ-707
581 Report config element+rule when ICU status is "failure".
583 ZOOM: stop fetching if present response has no records YAZ-710
584 Some targets return less records than their hit count would suggest.
585 This prevents ZOOM from continuing to fetch records if any present
586 response has 0 records in the response.
588 Ensure that GFS calls exit if any listener fails YAZ-710
589 Before, if XML config was in use, it would start the default
594 yaz-ztest: -V shows version (like yaz-client -V)
596 New iconv encoding: danmarc YAZ-692
598 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
600 daemon: only wait for immediate child rather than all children. YAZ-704
602 yaz-client: fix setting of SRU record schema. If scheme was unset, it
603 could lead to invalid memory reference.
607 yaz-ztest returns schema for MARCXML test records. SRU require that
608 recordSchema for records.
610 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
611 instead of non-surrogate diagnostic. This is a per-record failure.
613 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
614 may refer to multiple listeners now. Attribute listenref is a comma separated
617 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
618 option is given for GFS, the dirname of filename (for -f) is used
619 as prefix for options such as cql2rpn, ccl2rpn, etc.
621 Content-Type charset fixes YAZ-701 . Do not inspect charset in
622 Content-Type header for SOAP when decoding SRU. The payload (XML)
623 itself tells what encoding it is. In response, never supply encoding
624 in Content-Type. The response payload (XML) tells what it is (with no
625 encoding in XML it's UTF-8).
627 HTTP decoding: allow blanks in URL paths YAZ-700
631 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
632 and facets. Ensure recordData and recordSchema are always present in
633 record element, because they are required.
635 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
638 Simplify in a lot of places using odr_strdupn.
640 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
644 Increase various buffers in GFS's statserv_options_block
645 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
646 This change makes many type-casts redundant, and, thus simplifies code.
648 Remove last bits of WAIS support.
650 Remove member 'size' from Odr_oct.
652 Slim down the public part of 'struct odr'. Most elements are not part
653 of struct Odr_private.
655 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
656 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
657 In particular facets are supported in both client - and server side.
658 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
659 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
660 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
661 both request/response). This is what a search handler in the GFS
662 will see (regardless of whether operating in SRU mode or Z39.50).
664 Changes to the srw.h (SRU/Solr) definitions include:
665 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
666 (char*), which replace union query and query_type (int). This is because
667 SRU 2.0 supports a queryType parameter. This also means that, to carry
668 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
669 x-pquery=PQFstring (extention parameter). The extension parameter
671 - New element, packing, that has information about SRU
672 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
674 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
676 New element, packing, in Z_SRW_explainRequest.
678 New elements in Z_SRW_scanRequest, queryType and scanClause.
679 These replace query_type and scanClase untion. This is similar to what
682 --- 4.2.69 2013/10/01
684 GFS: log when closing down - at least SIGTERM YAZ-684
685 Also change formatting WRT PID logging a bit.
687 Improve display of MARC records with multi-byte subfield IDs YAZ-695
688 In some rare cases subfield identifiers are multi-byte characters.
689 This will try to deterime length of those and split accordingly.
690 This affects display in line mode as MARCXML/MarcXchange. The encoding
691 of ISO2709 is the same.
693 Change inp argument to const for yaz_read_UTF8_char.
695 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
697 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
699 Better check of marc leader info YAZ-691
700 Problem is that some systems generate MARCXML/MarcXchange with
701 funny headers. These will not work if encoded as ISO2709.
702 Some tests produce new output, due to updated warning messages
704 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
706 yaz-client: display MAB records YAZ-689.
707 Thanks for Heiko Jansen for this patch.
709 New utility z_get_HTTP_Response_server which allows both HTTP server name
710 and HTTP server URL to be given in response.
712 Debian: do not depend on obs tcl8.3.
714 Debian: do not depend on obs libicu36-dev.
716 --- 4.2.68 2013/09/23
718 GFS: pass additionalSearchInfo to search memeber search_input if
719 given. Otherwise pass otherInfo. Request for facets and other search
720 related things will be passed there in future versions of YAZ.
722 New ZOOM setting, authenticationMode, which allows authentication
723 paramters to be encoded in the URL rather than via HTTP Basic auth.
726 rpn2solr: fix nested AND/OR handling. YAZ-685
728 Add comparison routines for some Z-types, such as NamePlusRecord,
729 RPNQuery, Query, RecordComposition and OtherInformation.
731 --- 4.2.67 2013/09/19
733 Don't decode MAB as MARC. Just like we don't attempt to decode
734 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
736 CCL: allow quoted terms for date ranges. YAZ-681
738 Introduce ccl_parser_qual_search. This function makes old function
739 ccl_qual_search, from YAZ 2, available again.
741 Add yaz_facet_list_to_wrbuf. YAZ-683
743 --- 4.2.66 2013/09/11
745 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
746 schema was given for search. YAZ-675
748 Add Solr date range searches. YAZ-621
750 --- 4.2.65 2013/08/22
752 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
754 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
756 ISO2709/MARC parse most octet aligned records; not just those that
757 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
758 MARC parse more records instead of just dumping as is. YAZ-670
760 ZOOM: proper caching for variations of record schema. YAZ-671
762 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
764 --- 4.2.63 2013/07/17
768 --- 4.2.62 2013/07/11
770 New utility z_get_HTTP_Response_details - an extended version of
773 New utility yaz_url_get_error which returns error message of last
774 failed yaz_url_exec call.
776 yaz-url and url functions: allow max HTTP redirects to be controlled.
778 New functions yaz_file_glob2, yaz_xml_include_glob.
779 These functions takes a flags parameter, which, for now only controls
780 whether to fail inclusion of a non-existing file (without glob
781 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
783 --- 4.2.61 2013/06/20
785 For MARC XML parsing, allow record without leader. A fake/default leader
786 is inserted and a warning is tagged with the record.
788 ICU: fix leak in in icu_iter_get_org_info.
790 --- 4.2.60 2013/06/14
792 ICU: fix bug in icu_iter_get_org_info (un-init variable).
794 --- 4.2.59 2013/06/11
796 Implement z_HTTP_header_remove.
798 --- 4.2.58 2013/06/11
800 ICU: Disallow 0 ptrs for some ICU string utilities.
802 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
803 returns original tokens (before normalization).
805 CCL: avoid z39.58/regex truncation when not needed. Apply only the
806 conversion of those masks, when absolutely necessary.
808 CCL: configurable masking character - @mask. Default masking character
811 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
812 full response anyway, so a Transfer-Encoding header will obstruct the
815 --- 4.2.57 2013/05/15
817 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
818 picking a socket. Problem is that some systems has IPV6 support, but
819 we can't create sockets for them, so we pick AF_UNSPEC first.
821 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
822 use content_len to determine resulting Content-Length in HTTP response
823 and NOT Content-Length supplied in headers by user.
825 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
826 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
828 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
831 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
832 with big endian and unsigned char (by default).
834 --- 4.2.56 2013/04/26
836 Fix yaz-client connect (crash in 4.2.55).
838 --- 4.2.55 2013/04/26
840 Fix proxy/host problem for ZOOM that could occur if unix sockets
843 New Debian package libyaz4-dbg.
845 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
846 differently in tcpip_close.
848 --- 4.2.54 2013/04/17
850 Windows installer of YAZ includes YAZ4J as a component.
852 CQL: allow "extra terms" again, by default. Thus, the CQL parser
853 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
854 and earlier. CQL parser may operate in strict mode where queries
855 not conforming to the standard BNF are rejected (syntax error).
856 Whether the CQL parser operates in strict mode is controlled with
857 cql_parser_strict . Strict mode enabled with option -S for utilities
858 cql2pqf and cql2xcql .
860 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
862 --- 4.2.53 2013/04/10
864 New charset, MARC-8c, which is like MARC-8 but allows control characters
865 0x01 through 0x1F, except ESC to be passed through verbatim.
867 Fix a problem with duplicate sub field character in MARC output. Problem
868 happened only when output was MARC-8 encoded.
870 --- 4.2.52 2013/04/03
872 yaz-ztest: Use hash for fake hit count. Before, random number was used.
873 This is problematic for unit tests using yaz-ztest. This patch also makes
874 a hash for CQL queries. For RPN, any term with a leading digit will be
875 treated as pseudu hit count (to force any particular hit count by a client).
877 yaz-ztest: return unique MARC dummy records. Beyond record offset
878 24, the author surname is patched with offset to make all records
881 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
882 on system wide default (/proc/sys/net/ipv6/bindv6only).
883 @4 binds to IPV4 only. @6 binds to IPV6 only.
885 Update CQL API documentation a bit
887 CQL: don't accept extra terms for queries. Makes the CQL parser
888 stricly conformant to the standard.
890 --- 4.2.51 2013/02/12
892 GFS: scan handler gets extra_args from request and may return extra
893 response data . That's for SRU only.
895 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
897 --- 4.2.50 2013/01/30
899 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
901 OPACXML: sync spelling of availabilityDate in XML to that of Schema
902 opaxxml.xsd. The schema had the correct spelling of this member always.
903 The ASN.1 was mis-spelled and still is (API change) - we are
904 not changing this. However, the OPAC to XML conversion had yet
907 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
910 New function, z_ext_record_oid_nmem, which is similar to
911 z_ext_record_oid but takes NMEM rather than ODR
913 --- 4.2.49 2013/01/18
915 ICU: New conversion element 'join' which joins tokens into one
916 with a custom character given by rule attribute.
918 --- 4.2.48 2013/01/10
920 New GFS search member: present_number. This is a hint to the
921 search handler how many records are going to be fetched immediately
922 following search. There's no guarantee that it's going to be the case,
923 since it depends on hit count (for Z39.50 piggyback) and whether errors
926 Make a few functions static (private). The functions getbyte_stream,
927 ungetbyte_stream and yaz_gets are now private. They were never declared
930 yaz-marcdump: exit(5) for serious decoding errors
932 ISO2709 decoding: be more picky WRT header
934 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
935 was only used as to indicate that next-result-set-position should be
937 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
938 Based on patch from Ashley Sanders.
940 Make some functions static/private in PQF parsing. Those functions were
941 never declared in a public header and so should not be in use by
942 applications based on YAZ.
944 --- 4.2.47 2012/11/23
946 ZOOM: special options to control APDU logging.
947 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
948 logging of APDUs until "saveAPDU" option is set again. If logging is
949 already enabled the effect is that current APDU buffer is cleared.
950 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
951 logging (default behavior on new connection).
952 The APDUs sent/received can be obtained by using
953 Using ZOOM_connection_option_get(c, "APDU") or
954 ZOOM_connection_option_getl(c, "APDU", &l).
956 GFS: relay implementation_version from backend
957 From 3.0.40 and later, implementation_version from backend was
958 not used in init response at all.
960 --- 4.2.46 2012/11/15
962 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
963 mode at all. Probably never did.
965 Make a new version of ztest.pem that, at least, is not expired.
967 --- 4.2.45 2012/11/13
969 Fix description of CCL directive 'case'.
971 More tight checking of form arguments (yaz_uri_to_array). Makes
972 YAZ better at rejecting big and/or bad POSTs.
974 SRU decoding does not report more than up to 10 invalid arguments.
976 rpn2cql: less quotes in generated terms. Semantics unchanged, but
977 it's prettier this way.
979 --- 4.2.44 2012/10/25
981 New utility yaz_decode_init_diag. Defined in proto.h.
983 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
984 given for unix local socket.
985 The COMSTACK string for doing so is:
988 unix:/myfile:tcp:localhost:9999/mybase
989 unix:/myfile:localhost:9999/mybase
990 unix:/myfile:http://fakehost/mybase
992 debian: Use dpkg-buildflags in build process.
994 --- 4.2.43 2012/10/19
996 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
997 global's SRU service uses a recordPosition scheme starting from zero.
998 First record's position should be one
999 according to the standard.
1001 --- 4.2.42 2012/10/18
1003 Allow more namespaces for SRU. This is to allow, for example, an
1004 incorrect namespace returned from server
1005 http://services.igi-global.com/sru .
1007 Minor fixes for compilation on Windows.
1009 --- 4.2.41 2012/10/11
1011 daemon: log total number of bad signals from child on stop so that it
1012 is more easy to spot problems with child worker processes.
1014 retrieval: empty backend name attribute omits element set
1015 from being used in retrieval.
1017 --- 4.2.40 2012/10/04
1019 Implement Solr sort strategy "solr", similar to sru11 sorting.
1020 This will implement the correct parameters on Solr requst to do
1023 --- 4.2.39 2012/09/28
1025 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
1028 MARC: Extra/missing indicator handled for MARCXML.
1029 The indicator length is given in header and is the same for the
1030 whole record. If attributes ind1, ind2 are missing, then content
1031 character defaults to blank. Extra indicator attributes (beyond)
1032 indicator length are treated as an error.
1034 Reformat: delete trailing whitespace
1036 --- 4.2.38 2012/09/17
1038 MARC: fix non-ASCII characters for leader. This is to ensure we can
1039 generate XML in UTF-8.
1041 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
1042 in one node with structure word.
1044 --- 4.2.37 2012/09/04
1046 yaz-json-parse: JSON output may be pretty printed by using option
1049 Increase default value of max message for Z39.50 Init for GFS, ZOOM
1050 and yaz-client. Old value was 1 MB. New value is 64 MB.
1052 --- 4.2.36 2012/08/22
1054 yaz-client: don't display bogus records from SRU servers. Some SRU servers
1055 return more records than given by *maximumRecords*. Skipping those in
1058 record_render: simplify buffer return handling and fix at least one bad
1059 memory reference, that broke the test_embed_record sometimes.
1061 Allow http://user:pass@host notation for yaz_url_exec.
1063 zoomsh: allow shell command to be executed. Via the system(3) call.
1065 yaz_poll: Allow num_fds == 0
1067 yaz-client: fix bad encoding of "itemorder item". The itemorder
1068 item <no> - command forgot to use length of encoded Item Request
1069 package. Error present since YAZ 3.
1071 yaz-ztest: fix bad usage of session handle. Bug was introduced when
1072 result sets were saved (271a9c83).
1074 SRU recordPacking: guess record packing in response rather than looking
1075 at the recordPacking element which, OF COURSE, changed semantics in SRU
1078 Decode SRU 2.0 responses. The official namespace for responses, according
1079 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
1080 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
1081 nature.com's server, however, usee namespace
1082 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
1083 we are now using a glob-expr to match up the namespace. ZOOM C and
1084 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
1085 I can not find a single real example showing the "real" namespace in
1086 the documentation from OASIS. The namespace for requests is different
1087 from responses, but this is not added to YAZ yet, when we don't encode
1090 --- 4.2.35 2012/06/26
1092 zoom/record_render: add support for Base64 decoding fo MARC records
1093 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
1094 which will decode base64 + ISO2709 marc-8 encoded material from text node
1097 --- 4.2.34 2012/06/07
1099 Add missing definitions ZOOM_resultset_get_facet_field_by_index
1100 and ZOOM_resultset_facets_names.
1102 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
1105 Change APDU dump printing to avoid long leading blanks. For levels 16
1106 or larger the level is shown and the indentation is truncated but
1107 recursed with modula 8. This makes it still reasonable easy to read
1108 - even for nested BER dumps.
1110 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
1111 return 0 (incomplete package) in case where the BER package was
1112 considered too nested (return value of -2).
1114 dumpber: lines of level 15 are not indented further. Two spaces per
1115 indentation; indentation 15 or more is indented to a fixed indentation
1116 and augmented with a level=<no> indication.
1118 zoomsh: increase max size of command+args
1120 GFS: No limit in RPN buf size in CQL to RPN conversion.
1122 --- 4.2.33 2012/05/09
1124 New function for daemon utility, yaz_daemon_stop .
1126 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
1128 --- 4.2.32 2012/04/25
1130 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
1131 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
1133 --- 4.2.31 2012/04/23
1135 YAZ daemon utility relays SIGUSR1 to child process.
1137 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
1138 would result in en empty database list - which in turn would result in
1139 encoding failure for search.
1141 Fix reading beyond string in yaz_sort_spec.
1143 --- 4.2.30 2012/04/11
1145 Add two new SRU diagnostics:
1146 236: Access to specified database denied
1147 1015: Init/AC: Maximum number of simultaneous sessions for Userid
1149 Document the very useful ZOOM-C option "apdulog".
1151 CQL to RPN: term may be passed through verbatim. This is enabled with
1152 truncation.cql . The assumption being that the term is already CQL.
1154 --- 4.2.29 2012/03/20
1156 record_conv: leader spec may be given for marc element.
1157 The leader spec is given as attribute leaderspec for element marc.
1158 For example to convert a MARC21 record from MARC-8 to UTF-8:
1159 <marc inputformat="marc" outputformat="marc"
1160 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
1162 record_conv: allow user-XSLT params. For example:
1163 <xslt stylesheet="MARC21slim2DC.xsl">
1164 <param name="myparameter" value="myvalue"/>
1165 <param name="otherparameter" value="othervalue"/>
1168 record_conv: fix error handling for missing marc charsets.
1170 CQL: fix extra terms in wrong order.
1172 --- 4.2.28 2012/03/06
1174 record_conv: modify new API for conversion types. The conversion types
1175 may be passed in new functions yaz_record_conv_configure_t and
1176 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
1178 Avoid mixed statement/variable declare; fixes compilation with Visual
1181 --- 4.2.27 2012/02/28
1183 Add non-standard SRU diagnostic: 235: "Database does not exist".
1184 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
1185 Update SRU to Bib-1 diagnostic maps accordingly.
1187 CCL: add two new diagnostics for unsupported masking. The new
1188 diagnostics are: "Embedded truncation not supported" and
1189 "Single charcacter mask not supported".
1191 --- 4.2.26 2012/02/23
1193 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
1195 --- 4.2.25 2012/01/11
1197 Build YAZ for Ubuntu Oneiric.
1199 CCL: allow parantheses for proximity operands. For example CCL query
1200 (a) % (b) is now allowed.
1202 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
1203 marked dead, rather then being destroyed. If not, the session memory is
1204 being free'd before the search/scan handler is finished. Also destroy
1205 'request' memory in request_release rather than in various places,
1206 which resulted in leaks from time to time.
1208 --- 4.2.24 2011/12/21
1210 cql_sortby_to_sortkeys: honor sort prefix.
1212 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
1213 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
1214 The rpn2cql family of functions now always returns quoted CQL terms.
1216 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
1218 --- 4.2.23 2011/12/15
1220 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
1221 sequence is treated as one. For example, &&a=b&&&c& is identical to
1224 --- 4.2.22 2011/12/05
1226 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
1227 APDUs for a connection to a WRBUF.
1229 --- 4.2.21 2011/11/23
1231 Fix cql_sortby_to_sortkeys. Completely broken before.
1233 Make CCL's @truncation work again.
1235 --- 4.2.20 2011/11/09
1237 New ZOOM connection setting: tproxy. It's like proxy, but does not
1238 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
1239 to set resolved address + port for a connection outside ZOOM itself.
1241 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
1243 --- 4.2.19 2011/11/07
1245 Fix uninitialized variable in Solr spell support (could cause SEGV
1246 for SRU response decoding).
1248 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
1249 back-end's addinfo through into the ZOOM response addinfo.
1251 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
1252 they are separated by a colon and a space rather than simply
1255 --- 4.2.18 2011/10/28
1257 Add support for Solr spell-checking/suggestions through ZOOM.
1258 If a Solr target has been configured correctly for spelling-checking
1259 and suggestions, these will now be returned on the ResultSet option
1260 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1262 --- 4.2.17 2011/09/28
1264 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1265 with a flag whether to substitute escape sequences or not.
1267 --- 4.2.16 2011/09/22
1269 Fix nmem_strsplit_escape to substitute escape char properly.
1271 New option for zoomsh -e , which makes it abort on first error and
1272 return process exit code to indicate success/failure.
1274 YAZ options utility supports special option -- which makes all it treat
1275 all following arguments as non-options.
1277 --- 4.2.15 2011/09/16
1279 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1280 searched if absolute filename is given.
1282 Fix conv_xslt() error-reporting when stylesheet is not found.
1283 (The value of fullpath is meaningless in this situation.)
1285 --- 4.2.14 2011/09/07
1287 Fix problem in CQL sort node creation: un-initialized memory.
1289 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1290 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1291 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1294 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1295 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1297 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1298 will make it possible to use both single-character mask (#) and wildcard (?)
1299 in CCL . Throw diagnostic for left truncation because that is not supported
1302 --- 4.2.13 2011/09/01
1304 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1305 cases using escapes (\-sequences) and masking.
1307 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1308 would result in a read one byte beyond string.
1310 rpn2ccl may use Z39.50 masking for terms (t=z).
1312 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1314 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1315 not --cppflags (which seeems like an error in icu-config).
1317 --- 4.2.12 2011/08/27 RPM package only
1319 cql2ccl: fix conversion of terms: operator characters were not
1322 --- 4.2.11 2011/08/25 RPM package only
1324 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1325 CCL parser will map both # and ? to their regular expression
1326 quivalents (. and .*).
1328 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1329 of reserved CQL characters.
1331 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1332 is, so that they are passed through.
1334 --- 4.2.10 2011/08/24
1336 ZOOM SRU mode: more aggressive re-connect.
1338 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1339 made available as a utility function, declared in <yaz/logrpn.h>
1341 rpn2cql_structure() supports proximity nodes (except that the Type-1
1342 proximity node's "exclusion" binary is ignored, as there is no way to
1343 express that in CQL). Fixes bug #4564.
1345 --- 4.2.9 2011/08/18
1347 Fix SEGV that could occur if set command of zoomsh was given without
1348 value (2nd argument).
1350 Fix SEGV that could occur if unsupported transport was given for
1351 COMSTACK - say https (when SSL was unavailable).
1353 Build yaz-url on Windows too.
1355 --- 4.2.8 2011/08/11
1357 New utility to get web content. Header is url.h. A command line tool
1358 yaz-url is part of the distribution and packages.
1360 Fixes for SSL COMSTACK (when gnutls is in use).
1362 New functions yaz_base64{encode,decode}. Header is base64.h.
1364 --- 4.2.7 2011/08/03
1366 ZOOM C includes HTTP response buffer as additional info if it fails
1367 to decode the SRU response.
1369 Make wrbuf_json_puts available.
1371 --- 4.2.6 2011/07/28
1373 zoom: throw diagnostic for invalid value for option "sru". Before a
1374 bad SRU request was sent.
1376 Adding new utility wrbuf_vp_puts.
1378 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1380 --- 4.2.5 2011/07/21
1382 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1383 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1384 redirect was used at the same time.
1386 MARC line mode decoding: be less picky about length given - first
1387 5 digits of header that is.
1389 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1391 Changes to decoding of SRU records: a record with recordPacking=xml is
1392 modified with a new root element <yaz_record> if the recordData contains
1393 multiple children elements. This is to make the record XML parseable
1396 RPN to Solr conversion: encode special characters.
1398 Generic Frontend Server: fix uinitialized member, stepSize.
1400 --- 4.2.4 2011/06/21
1402 Fix a bug in SRU decoding of records.. The database records stored
1403 had un-initialized memory, but it would only be seen with yaz_record_render
1404 and type_spec="ext" .
1406 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1408 --- 4.2.3 2011/06/17
1410 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1412 --- 4.2.2 2011/06/10
1414 Add new utilities to convert from CQL to CCL . These utilities have
1415 prefix cql_to_ccl defined in cql.h.
1417 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1418 lead to memory heap corruptions when ICU utilities were in use.
1420 --- 4.2.1 2011/06/07
1422 Make compilation work without Libxml2.
1424 yaz-client: remove redundant blanks in display of searchResult-1 term
1427 --- 4.2.0 2011/05/18
1429 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1430 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1432 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1433 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1434 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1435 Note that the CQL sortby spec is only converted when the GFS is already
1436 converting from CQL to RPN (cql2rpn element).
1438 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1439 specify whether to collapse delimitors or not. The existing nmem_strsplit
1440 do collapse (collapse parameter = 1).
1442 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1444 Rename internal func yaz_use_attribute_create. While non-static, this
1445 function is not declared in a public header.
1447 --- 4.1.7 2011/03/15
1449 Add -lCrun when linking with ICU on Solaris.
1451 More quicks character set conversions for OPAC records.
1453 --- 4.1.6 2011/03/10
1455 fix problem with record_render: records were converted (character set
1456 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1458 --- 4.1.5 2011/03/08
1460 SRU: add methods for handling DADS SRU-proxy facets.
1462 Separate OPAC record character set for ZOOM_record. yaz_record_render
1463 allows a character set given as charset=from/opacfrom,to where 'from' is
1464 the character set of a bibliographic record, 'opacfrom' is character set
1465 of OPAC record and 'to' is the target character set.
1467 --- 4.1.4 2011/02/21
1469 yaz-client: show may XML format records. Command show followed by 'format'
1470 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1473 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1476 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1478 --- 4.1.3 2011/01/27
1479 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1481 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1482 this package can be distinguished from other vendors.
1484 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1485 as determined by configure
1487 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1489 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1490 returns no error and no record, the present request is considered
1491 partial (only a subset of the records could be returned by backend), and
1492 so it is appropriate to set Present Status to partial-4.
1494 --- 4.1.2 2010/11/02
1496 Move yaz-config man pages to section 1.
1498 More documentation about Solr.
1500 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1501 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1502 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1503 peers on some Linux systems. However, in general that does not work
1504 so YAZ can not rely on that to work. Debian changed behavior in this
1505 respect from Debian lenny to Debian squeeze (still testing as of Oct
1507 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1509 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1511 --- 4.1.1 2010/10/05
1513 Fix yaz-config output: echo_source not set correctly by configure.
1515 --- 4.1.0 2010/10/05
1517 Solr Web Service support for yaz-client and ZOOM.
1519 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1521 --- 4.0.12 2010/08/17
1523 Z39.50 facet support. Facet specifications are passed for search in
1524 other-information with ASN.1 as defined in facet.asn and OID
1525 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1526 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1527 3 is limit (number of entries to get in response). yaz-ztest returns
1528 dummy facets if a client asks for them.
1530 --- 4.0.11 2010/07/09
1532 CCL fixes: bug 2895 and bug 3539.
1534 GR1-display: add comma in display - was removed by mistake in
1537 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1539 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1541 --- 4.0.10 2010/06/18
1543 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1544 result set from a connection. The result set will be on its own
1545 thereafter; no operations on it will perform retrievals from a target.
1546 Only cached copies are returned.
1548 ZOOM C:fix case for HTTP servers responding with Connection:close.
1549 Ensure that if there is a current task it is resumed (like fetching
1550 more records in a result set) . Bug #3484.
1552 PQF parser: use odr_atoi for Odr_int (not atoi)
1554 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1555 values that contain any non-digits are treated as string attributes
1556 (previously decoding only checked for leading character ([0-9]). PQF
1557 encoding: attribute string values are not surrounded by double-quotes.
1559 --- 4.0.9 2010/05/21
1561 New utility for managing threads - thread_create.h.
1563 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1564 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1565 but YAZ' implementation do.
1567 Fixes for yaz_cond-functions on Windows 7.
1569 DLL export more symbols.
1571 zoomsh: show record do NOT render opac.
1573 Remove *.la files from Debian and RPM packages.
1575 --- 4.0.8 2010/05/11
1577 Debian package libyaz-dev depends on libgnutls-dev again (was
1578 removed in YAZ 4.0.6, but due to Libtool it is still needed
1579 even though yaz-config do not list libgnutls libs).
1581 ZOOM: Use only one WRBUF for returning string results for
1582 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1584 ZOOM: ZOOM_connection do not use a shared pointer to
1585 ZOOM_resultset after ZOOM_resultset is destructed by
1586 user. Reverts to YAZ 4.0.4 behavior.
1588 --- 4.0.7 2010/05/04
1590 record-conv: fix problem with at least one XSL conversion -
1591 due to probably incorrect usage of XML XSL documents.
1593 --- 4.0.6 2010/04/29
1595 Fix yaz-config for static mode and the use of SSL (gnutls).
1597 --- 4.0.5 2010/04/29
1599 Forward decl timeval struct in mutex.h and gettimeofday.h.
1601 yaz-config: fix 'static' mode linking.
1603 --- 4.0.4 2010/04/28
1605 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1606 are wrappers for pthreads or Windows. For Windows these are put in
1607 a separate DLL: yaz_cond4.
1609 libyaz.la (whole source) is compiled with thread. If thread support
1610 is enabled enabled, all source of YAZ is compiled with treading support.
1611 This allows core utilities such as yaz_log to use thread facilities.
1612 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1613 thread utilities. This commit moves mutex utilities (mutex.c) from
1614 libyaz_server.la to libyaz.la.
1616 yaz-json-parse displays leading text until error.
1618 --- 4.0.3 2010/04/09
1620 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1621 patch from Giannis Kosmas.
1623 SRU: no longer URL encode SRU database. The URL for an SRU server is
1624 a URL and such is alreeady encoded - at least when given with leading
1625 http:// or https://. This reverts behavior to YAZ 3.0.50.
1627 Support for new MARC XML notation TurboMARC which like MARCXML is a
1628 complete representation of MARC/ISO2709.. This one, however, is more
1629 compact and allows for faster processing with XSLT. TurboMARC can be
1630 used in the marcdisp.h API, from the yaz-marcdump utility and from
1633 yaz-ztest can be configured - via the database - to perform certain
1634 delays when it performs operations search, present and single record
1635 fetch. This allows testers to make yaz-ztest act as a real or even slow
1636 Z39.50 server. Refer to the yaz-ztest man pages for details.
1638 --- 4.0.2 2010/03/09
1640 wrbuf_destroy allows NULL WRBUF passed to it.
1642 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1644 Add ZOOM_connection_close.
1646 No fixed size buffers for ZOOM shell - bug #3257.
1648 tstodr: make it work on s390 platform.
1650 New icu iterator-functions. The new icu_iter-functions makes it possible
1651 to use ICU chains from many threads.
1653 yaz-client: better syntax check for show command.
1655 --- 4.0.1 2010/01/26
1657 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1660 New simple local-file XML include facility which allows file glob-patterns.
1661 Refer to yaz/xml_include.h.
1663 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1666 ZOOM_record_get supports new parameter "format" which makes it format XML
1669 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1670 JSONText in ECMA-262) is JSONValue, not JSONObject.
1672 --- 4.0.0 2010/01/20
1674 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1675 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1677 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1678 POSIX/Unix builds .so with major version 4.
1680 Remove old LOG_-defines from log.h. They have been obsolete and
1681 undefined by default for the last 5 years.
1683 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1685 GFS: Remove socket (int *fd) from search_rr handler. The socket
1686 descriptor ptr is a facility that allowed a search handler to supply
1687 a socket which would serve as a callback - when search was complete.
1688 This facility has now been in use for years.
1690 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1691 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1692 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1693 returns 'const char *' rather than 'char *. The returned string is
1694 read-only and should not be modified by applications. COMSTACK cs_close is
1695 now a void function - it no longer returns int. No applications check for
1696 the value and the implementations has always returned 0.
1698 ZOOM: use size_t for scan hit counts and str size. Functions
1699 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1700 occ (hit count) and len (string length) are now of type size_t pointer
1701 rather than int pointer. This is to be able to represent large hit counts
1702 and to also just to use the proper type for string length (strlen result).
1704 New JSON parser. Refer to include/yaz/json.h .
1706 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1707 Used to be int in some cases. Many wrbuf_-functions used to return an int
1708 indicating some length.. These return values were never used. And so they
1711 ODR: odr_malloc, odr_total now takes size_t for size.
1713 clone_z_type: fix leak; occurred for encoding failures.
1715 --- 3.0.52 2009/12/03
1717 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1718 bug was introduced in 3.0.51.
1720 --- 3.0.51 2009/12/02
1722 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1724 tcpip comstack: fix leak for getaddrinfo.
1726 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1727 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1728 Decoding of SRU "path" database is performed by private function
1729 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1730 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1732 yaz-client: honor base command for SRU. Change when database setting
1733 is applied for SRU and ensure it is kept when a connection is reset.
1734 Change also the way errors are displayed or SRU (decoding of packages).
1736 --- 3.0.50 2009/11/02
1738 Add support for extra request / response data for SRU codecs and GFS.
1739 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1740 for extra data response buffer and length. For the GFS, both request
1741 and response data (XML) is carried in extra_args and extra_response_data
1742 for the search handler. Patch by Ko van der Sloot.
1744 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1745 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1746 10010). This fixes bug #2113.
1748 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1749 cmdfile included a 'quit' command that would result in a memory violation.
1751 --- 3.0.49 2009/10/01
1753 Make a number of functions defined in xmlquery.c static. These have
1754 never been declared in a public header file (yaz/xmlquery.h) and was
1755 made public by mistake.
1757 Improve speed of character conversions (iconv utilities). This makes
1758 conversions from MARC-8 faster.
1760 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1761 unless type desired is "raw". This will prevent type "xml" from
1762 returning ISO2709 .. Which obviously can not be XML parsed.
1764 Fix memory leak in ZOOM that would occur if option apdulog was used
1765 on a re-used connection.
1767 Frontend server logs HTTP requests.
1769 Frontend server now sends Z39.50 close when it times out (sesssion has
1770 been idle for too long). Versions 2.0.30 and earlier also sent close.
1771 But due to a mistake this was disabled in all versions after that, i.e.
1772 the server would just close the socket immediately.
1774 yaz-client emits a better message when receiving an unrecognised
1775 userInformationField.
1777 Skip zero-length subfields when decoding ISO2709. This rare case happens
1778 if a record has two FS characters in a sequence. Without this patch
1779 there would be a reference beyond char array in using_code_len fragments
1782 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1784 --- 3.0.48 2009/08/28
1786 The show command offered by the zoomsh command now takes a 3d optional
1787 parameter type which is what is passed to ZOOM_record. If the type
1788 argument is omitted, "render" is used.
1790 RPN to CQL conv may use USE string attributes (bug #2978).
1792 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1794 --- 3.0.47 2009/07/08
1796 Function yaz_xml2query allows a diagnostic element in the PQF XML
1797 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1798 code and additional info respectively.
1800 The BER BOOLEAN is now the integral type Odr_bool which still happens
1801 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1802 typedef'd to Odr_int. This is still an integral 'int', but it may be
1803 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1804 ASN-1 compiler as well as programs has been updated to use the new types.
1806 --- 3.0.46 2009/06/08
1808 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1809 only the bibliographic record was rendered. For type=opac, an OPAC
1810 record is only returned if it is present.
1812 iconv: small fix for encoding of advancegreek.
1814 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1816 yaz-client: option auto_reconnect=on really reconnects.
1818 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1820 server: avoid null ptr ref for for yaz_poll errors.
1822 build: fix RPM build for RHEL 5.3.
1824 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1826 --- 3.0.45 2009/03/31
1828 Fixed bug #2709: TCP connect returns Invalid argument.
1830 Fixed compilation for mingw.
1832 Honor charset for raw records (ZOOM_record_get).
1834 Fixed use of errno for threaded mode that was seen on Solaris 10.
1836 Fixed argument passing with blanks in value for Windows Service.
1838 Disable YAZ' own log rotate by default (no 1 GB limit).
1839 The variable l_max_size which specifies the log file limit is set to 0
1840 (DISABLED): This is due to the fact that YAZ is most often deployed using
1841 logrotate. Also YAZ can not perform log rotate because of unsufficient
1842 permissions (setuid).
1844 --- 3.0.44 2009/02/17
1846 List supported encodings in man page for yaz-iconv.
1848 Fixed missing SSL libs for --libs output
1850 Re-established OID record syntax application-xml. Nobody should use it
1851 but we don't want to change soname because of this symbol being absent.
1853 --- 3.0.42 2009/02/02
1855 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1857 Added member named_result_sets for init handler struct for the GFS. This
1858 allows a server to disable named result sets.
1860 Removed OID record syntax application-xml.
1862 Added support for rule-based transliterator for ICU wrapper of YAZ.
1864 Fixed bug #1902: yaz-icu XML output.
1866 Make YAZ checks Emacs friendly.
1868 BITSTRING value shows value. Bug #2346.
1870 ISO2709 decoding: skip control characters from indicator data.
1872 Omit sort key by default in yaz-icu's output.
1874 Allow combined single char options (again) for YAZ' options function.
1876 Utility yaz-marcdump got option to display YAZ version (-V).
1878 Allow YAZ to use ICU 3.4.
1880 Added new ICU test case which illustrates removal of diacritics.
1882 --- 3.0.41 2008/12/29
1884 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1886 --- 3.0.40 2008/12/29
1888 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1891 Fixed bug #2352: yaz-marcdump crashes for certain record.
1893 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1895 Added support for Danmarc2 to UTF-8 conversion.
1897 Added support for ISO5426 to UTF-8 conversion.
1899 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1900 implementation version.
1902 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1904 --- 3.0.38 2008/11/10
1906 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1907 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1909 ZOOM C now interprets databaseName option for ZOOM connection as path
1912 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1914 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1916 Dummy Libxml2 types no longer defined in headers of YAZ'.
1918 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1921 --- 3.0.36 2008/09/26
1923 Various ODR chapter fixes.
1925 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1927 Added missing source for Windows compilation, mutex.c.
1929 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1931 For SRU connections in ZOOM all records up to "count" are now fetched.
1933 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1934 in Windows due to bad error handling for Libxml2.
1936 Added facility for sending arbitrary records (ASN.1 any) using
1937 ZOOM C's Extended service update. Patch by Sam Reynolds.
1939 New options for ZOOM C's connection, logapdu which makes ZOOM log
1942 --- 3.0.34 2008/06/18
1944 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1946 --- 3.0.32 2008/06/12
1948 Fixed memory violation that could occur when decoding UTF-8. This bug
1949 was only present in 3.0.30 of YAZ.
1951 --- 3.0.30 2008/06/06
1953 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1954 GNU TLS is used by default (if found).
1956 yaz-ztest returns OPAC records if a client asks for OPAC.
1958 Improved speed of MARC-8 encoding.
1960 Added support for lossy and loss-less MARC-8 encoding.
1962 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1964 Added new Windows Service wrapper (sc).
1966 yaz-client's itemorder command may now send a file.
1968 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1970 Added new function yaz_log_xml_errors.
1972 Allow (but warn) unknown XML attributes in MARCXML parsing.
1974 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1976 The UTF-8 to MARC-8 conversion now uses a different set of characters
1977 for Greek symbols. Bug #2120.
1979 --- 3.0.26 2008/02/21
1981 Added yaz_daemon (daemon.h).
1983 Fixed bug #2068: pkg-config trouble
1985 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1987 --- 3.0.24 2008/01/28
1989 Document --with-xml2 option.
1991 Added OPAC XML XSD (etc/opacxml.xsd).
1993 Allow glob mask for name attribute in retrieval element for the
1994 generic frontend server's retrieval facility.
1996 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1997 except POLLIN/POLLOUT.
1999 Fixed error handling in cs_listen. Bug #2037.
2001 --- 3.0.22 2008/01/20
2003 Fixed version in yaz/yaz-version.h.
2005 Fixed bug #2027: Crash when closing connection.
2007 Changed configure so that ICU support is only enabled if only ICU
2008 and Libxml2 is available (because the ICU chain is XML based).
2010 --- 3.0.20 2008/01/15
2012 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
2013 is built. Only this DLL depends on the ICU runtime.
2015 yaz-ziffy is no longer part of YAZ. It is distributed separately by
2016 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
2018 Changed license of CCL module to 'Revised BSD'. After consultation with
2019 remaining members of the original EUROPAGATE consortium, we are re-issuing
2020 the CCL module without a separate license. The software was developed by
2021 Index Data as part of a research project. The special license was included
2022 to help feed usage information back to the project consortium to support
2023 project evaluation. At this time, the project consortium has long-since
2024 disbanded, and the majority of the original principals have retired. At the
2025 same time, we have significantly modified the software during the following
2026 years, to the point where very practically no original code remains. To
2027 simplify re-use of the software, we have contacted those members of the
2028 consortium who could be reached, and agreed to re-issue the module as a
2029 proper part of the YAZ package.
2031 Tcl scripts uses /usr/bin/tclsh as preferred shell.
2033 CQL closer to being version 1.2 compliant. CQL also allows free-form
2034 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
2037 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
2038 bug could make Extended services handling crash in the ZOOM layer. This
2039 bug was only present in YAZ 3.0.18.
2041 --- 3.0.18 2007/12/19
2043 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
2046 yaz-marcdump reads and writes collection wrapped records.
2048 Handle OPAC for record conversion module.
2050 Fixes for ICU wrapper.
2052 Allow ICU libs to be controlled with --with-icu .
2054 --- 3.0.16 2007/11/12
2056 Added yaz_poll which is a wrapper for select/poll. When poll is available
2057 and non-buggy, it is used, by yaz_poll . This allows more than 1024
2058 sockets to be in use.
2060 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
2061 functionality through an XML based configuration (ICU chain). This system
2062 is useful for search facilities such as Pazpar2 and Zebra that needs to
2063 perform tokenization of indexed material. The ICU code in a separate
2064 library libyaz3_icu.a.
2066 Added HTTP tunnel facility for COMSTACK, bug #1752.
2067 This is a facility that allows a Web proxy, such as squid, to tunnel
2068 Z39.50 traffic. This facility is "transparent" to must applications
2069 using YAZ. It's enabled by using pseudo transport connect: followed by
2070 the proxy address, followed by command, then follwed by he regular
2071 "virtual" addresss. For example,
2072 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
2074 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
2076 --- 3.0.14 2007/09/21
2078 Fixed bad memory reference in ZOOM_record - cuased by member not being
2079 initialized. This was a problem only in YAZ 3.0.12.
2081 Fixed bug in conversion from MARC to XML: Non-XML characters in control
2082 fields were not removed.
2084 Changed the way C code is generated from codetables.xml. Made a MARC-8
2085 conversion trie for each characterSet section rather than codeTable.
2086 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
2087 of codetables.xml from Larry Dixson, LOC. Bug #1464.
2089 --- 3.0.12 2007/09/12
2091 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
2092 from ZOOM_record_error).
2094 ZOOM C function ZOOM_record_get returns record schema for type="schema".
2096 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
2098 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
2100 Better SRW-to-Bib-1 diagnostic mapping.
2102 ZOOM C and yaz-client announces SRU version 1.2 by default.
2104 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
2107 Fixed in yaz_sru_decode to allow other version than 1.1.
2109 --- 3.0.10 2007/08/22
2111 Added support for SRU scan for ZOOM.
2113 Added support for the use of the older versions or Extended Service
2114 Update in ZOOM. To faciliate this, an option "updateVersion" may be
2115 set to the version , 1=first, 2=second, 3=third. The third version is
2116 what ZOOM C has used so far. And that, obviously, is the default.
2118 Added support for CCL queries in Z39.50 queries sent to the GFS (and
2119 therefore in Zebra and in SimpleServer-based applications). The new
2120 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
2121 qualifier file used to transform incoming CCL queries into Type-1 RPN,
2122 which is passed into the back-end search callback function.
2124 Added support for HTTP Basic authentication in clients: the SRU/W
2125 codec encodes the username/password elements of the PDU structure
2126 appropriately, and these may be set using the "user" and "password"
2127 options in ZOOM-C applications (the same options that are used for
2128 Z39.50 authentication).
2130 --- 3.0.8 2007/06/25
2132 Fixed bug #1208: SSL appears to be broken in ZOOM.
2134 Fixed bug #1206: Libxml2 include path weirdness.
2136 Added oid_name_to_dotstring.
2138 Allow elementSetName to be specified for ZOOM C record update.
2140 Allow waitAction to be specified for ZOOM C based for Extended Services.
2142 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
2143 syntax OID. Bug introduced in YAZ 3 series.
2145 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
2147 --- 3.0.6 2007/06/06
2149 Fixed bug #1157: yaz-client does not read .yazclientrc from current
2150 directory. yaz-client now reads commands from file given by option -f
2151 if specified; then tries to read .yazclientrc in current directory.
2152 Failing that, it reads .yazclientrc from user's home directory.
2154 Added support for correlationInfo Note and ID for Record Update via
2157 Added yaz-client command querycharset which specifies character set for
2158 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
2159 (termListAndStartPoint).
2161 Charset ISO5428:1984 is an alias for ISO5428-1984.
2163 Implemented a way to perform scan in a result set using Z39.50. This
2164 is achieved by attaching the result set name in the characterInfo
2165 (type InternationalString) of OtherInformation in the Scan Request PDU.
2166 The result set is identified in the otherinformation by the new OID:
2167 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
2168 This allows for scan in result set and faceted search . Zebra did some
2169 of this in the APT term using attribute type 8 and value being result
2170 set. Using the OtherInformation approach for this is cleaner and easier
2171 to work with in proxies and the like. This facility can be used in
2172 yaz-client using new command setscan which takes a result set as first
2173 argument, start position (APT) as second.
2175 Changed decoding of SRU XML packed records to deal with servers that
2176 have recordData with XML data with multiple root nodes. Also make
2177 comparison for recordPacking case insensitive. Again, one server
2178 returns "XML" where others return "xml".
2180 For SRU responses allow Content-Type application/xml as well as text/xml.
2182 --- 3.0.4 2007/05/21
2184 Fixed bug in character set conversion of BER strings. Bug introduced
2187 --- 3.0.2 2007/05/08
2189 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
2191 For OID class, use oid_class consistently.
2193 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
2196 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
2197 character set for bibliographic information interchange". By Giannis Kosmas.
2199 Added documentation on new OID API.
2201 --- 3.0.0 2007/05/02
2203 Changes to generic frontend server interface: added new member
2204 'query_charset' for bend_initrequest structure. A backend init handler
2205 should set this member to its native character set for query terms.
2206 When defined, the frontend server logic will announce this character set
2207 to a client if the negotiationModel bit is set by the client. All server
2208 implementors are encouraged to specify this. If a backend server does not
2209 specify this a warning is issued using yaz_log(YLOG_WARN,..).
2211 Added CCL utility to remove terms (stop words) from resulting RPN
2212 tree. This is handled by functions with prefix ccl_stop_words_ .
2214 New ZOOM C option, "rpnCharset", which allows client-side conversion of
2215 terms in RPN queries.
2217 Clean-up the CCL API. Moved some internal structures from ccl.h to
2218 private header cclp.h. Changed ccl_parser_create so that a Bibset must
2219 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
2220 This is replaced by ccl_parser_find_str which takes a string instead.
2222 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
2223 libyaz.la is the core of YAZ except the generic frontend server and
2224 does not depend on POSIX threads anymore. libyaz_server.la is the
2225 generic frontend server facilities and uses POSIX thread functionality
2226 if available. The libyaz.la no longer depends on POSIX threads because
2227 the number of global structures is limited. NMEM no longer re-uses blocks
2228 between threads ; it simply free's memory immediately but allocates in
2229 "large" chunks as usual. We don't expect any performance penalties
2230 because of this. The yaz_log system is still using a global log_level so
2231 caution must be taken when modifying it with yaz_log_init_.. +
2232 yaz_log_mask_str. This, however, should not cause any trouble because
2233 these functions are called during initialization of application code
2234 anyway. `yaz-config --libs server` returns libs for server applications;
2235 `yaz-config --libs` returns libs for non-server applications.
2237 New OID database - with public definitions in oid_db.h. Removed old OID
2238 database including the head oid.h and definitions such as enum oid_value
2239 and struct oident. The new OID database uses the same string names as
2240 before but the 'protocol' is gone. There are now only two representations
2241 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
2242 converts from string to OID; functions with prefix yaz_oid_to_string
2243 converts the other way.
2245 Change to emit_term() in CQL-to-PQF query translation: when a term has
2246 the /regexp relation modifier, do not process it for leading and
2247 trailing "^" and "*", which have quite different meanings in regular
2250 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2251 write handlers no longer carries a 'last' parameter. This will make
2252 yaz_iconv flush "less" characters. A flush is performed by call to
2253 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2255 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2256 removed, because function yaz_query_to_wrbuf does the same.
2258 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2259 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2261 Deprecated MARC utility functions removed.
2263 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2266 Branch split: YAZ_2_1_55_branch
2268 --- 2.1.54 2007/03/16
2270 Fix to ZOOM-C so that transparent reconnection is properly handled on
2271 connections that are in asynchronous mode.
2273 Fixed compilation on OpenBSD 4.0.
2275 Large strings in GRS-1 records are now properly displayed in yaz-client.
2277 Added character conversion support for "advancegreek"; based on patch from
2280 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2281 sequence is met. Before the error was not set so it would be unknown.
2283 Adjust yaz-marcdump MARC reader so that it skips until record separator
2286 --- 2.1.52 2007/03/07
2288 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2289 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2290 fd_set structure used as a bitmask for the FDs to be selected on.
2292 Using ACX_PTHREAD macro to check for POSIX threads.
2294 Fixed have-vsnprintf check.
2296 --- 2.1.50 2007/02/23
2298 Fixes for configure on BSD. Bug #900.
2300 Added snprintf/vsnprintf wrappers for systems that don't have
2301 limits (heavens forbid).
2303 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2304 created before all previous tasks were completed and removed from the
2305 task queue, the new task could be removed by a mistake.
2307 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2309 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2311 Fixed bug #832: Problem with MARC/charset in yaz-client.
2313 Fixed bug #668: save command line history for yaz-client.
2315 Fixed bug #830: pkg-config support.
2317 --- 2.1.48 2007/01/23
2319 Extended ZOOM result set options with two options that may be read by
2320 a client: resultSetStatus and presentStatus with values as specified for
2322 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2324 Fixed bug #827: Using SSL fails on Debian etch.
2326 Fixed bug #826: Weird looking chars for set of MARC records.
2328 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2329 that is treated as an ItemOrder with itemRequest being an XML document
2330 external. The value of "doc" is the content.
2332 Extended the GFS search facility. New member of bend_search_rr
2333 'estimated_hit_count' signals that hits is known to be an estmate
2334 (higher or lower than real hit count). New member 'partial_resultset'
2335 signals that the search was partial (hit count is lower or equal than
2336 real hit count). For Z39.50, the information is stored in resultSetStatus
2337 member of SearchResponse APDU. For SRU, the information is signalled
2338 via SRU diagnostic 59: "Result set created with valid partial results
2341 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2343 --- 2.1.46 2007/01/13
2345 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2347 Added ZOOM_connection_peek_event.
2349 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2350 the following new functions:
2351 ZOOM_event_nonblock, ZOOM_connection_process,
2352 ZOOM_connection_get_{socket,mask,timeout},
2353 ZOOM_connection_fire_event_{timeout,socket}.
2354 The existing blocking event handler, ZOOM_event, is a wrapper for the
2355 + blocking ZOOM_event_sys_{poll,select}.
2357 Implemented function ccl_xml_config which parses XML version of CCL
2358 configuration (bug #798).
2360 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2362 Added timings utility (yaz/timing.h)
2364 --- 2.1.44 2007/01/03
2366 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2369 Fixed bug #779: Rotation of apdu.log fails.
2371 Fixed for character set conversions:
2372 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2373 Honor G1 set in MARC-8 decoding.
2375 --- 2.1.42 2006/12/17
2377 Fixed bug #775: char conversion does not handle Alternative UTF-8
2380 Implemented function yaz_marc_read_line which parses MARC line format
2381 records. There is a wealth of formats out there. So far, this function
2382 reads line records produced by yaz_marc_write_line.
2384 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2385 more generic and easier to remember(!) options: -i format and -o format
2386 which specifies input format and output format respectively - where
2387 format is one of "marc", "marcxml", "line", "marcxchange".
2389 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2390 does not print anything except warnings for records.
2392 For yaz-marcdump, added support for MARC split into files (-s) with a given
2395 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2396 spec, at http://www.loc.gov/standards/sru/record-update/
2397 This has changed the binary layout of the following structs:
2398 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2399 bend_update_rr . Patch by Ko van der Sloot.
2401 Added GFS utility function bend_assoc_is_alive which returns 1 if
2402 association is still alive (client is connected); 0 otherwise (client
2403 closed connection). This allows busy servers to stop working for
2406 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2407 been a separate piece of software. This version of ziffy has been modified
2408 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2410 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2412 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2413 Client code may now interrogate options such as "init_opt_sort" to
2414 find out whether the server claims to support various options.
2416 --- 2.1.40 2006/11/27
2418 Added utilities yaz_{set,get}_esn to set/get element set name from
2421 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2422 of YAZ and has been so since YAZ 2.1.10.
2424 Implemented ZOOM_record_error which returns error information for
2425 record (surrogate diagnostic).
2427 --- 2.1.38 2006/10/31
2429 Updates for SRU Update by Ko van der Sloot:
2430 1. Changed name from "operation" to "action"
2431 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2432 versions in the code, marked as 'backward compatible'.
2433 3. Added diagnostics for SRU Update.
2435 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2437 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2439 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2441 For GFS, fixed problem with SRU diagnostic 'First record position out of
2442 range' being issued for 0 hits.
2444 zoomtst10 part of Windows Build.
2446 --- 2.1.36 2006/10/13
2448 Implemented yaz_filepath_comp which splits a path into file path
2449 components (required by Zebra 2.0.3+).
2451 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2452 BSD inspired license until now so this should not have any real impact on
2453 anybody. See http://www.opensource.org/licenses/bsd-license.php
2455 Fixed bug #687: Missing log lines.
2457 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2460 Fixed bug #689: SRU diagnostics to be added.
2462 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2463 whether a connection is idle (no more work do do).
2465 --- 2.1.34 2006/10/04
2467 Change type of optval from long to int for invocation of setsockopt with
2468 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2470 Added support for specifying the max log file size for the Generic
2471 Frontend Server. The size is given with option -r.
2473 --- 2.1.32 2006/09/21
2475 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2477 --- 2.1.30 2006/09/17
2479 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2482 Fixed bug in Generic Frontend Server that could cause a server to stop
2483 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2485 For the generic frontend server, the maximum record size is used as maximum
2486 size of incoming packages (SRU + Z39.50). The value until was previously
2487 only used in Z39.50 Init negotiation and, later, in a session controlled
2488 sizes of records returned. This is controlled using -k option. It can be
2489 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2491 --- 2.1.28 2006/09/04
2493 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2496 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2498 New option for yaz-marcdump -lpos=value which allows setting a portion
2499 of MARC header to a certain value.
2501 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2503 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2504 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2506 --- 2.1.26 2006/08/15
2508 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2511 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2513 --- 2.1.24 2006/08/08
2515 Fixed MARC ISO2709 encoding routines to deal with character set
2518 Minor changes to GFS logging. Database included in search request log
2521 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2522 cached/multiple records.
2524 Shared libraries are built by default on Unix+configure.
2526 Changed cql2pqf transformation to use a different evaluation order. The
2527 new order is: always, relation, structure, position, truncation, index
2528 and relationModifier. Old order was: always, relation, relationModifier,
2529 structure, index, position, truncation. Note that the the latter ones
2530 override former ones for identical attributes.. The new scheme means that
2531 it is possible to override any existing attribute with a relationModifier.
2532 And also that it is possible to override everything for the index rule
2533 (except the ones listed in relationModifier). No order is perfect but this
2534 one, we believe, covers more real cases.. The "always" should have been
2535 called "default", since the attributes there can be overridden with all
2538 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2539 compilation phase, but also for yaz-config --cflags output. This allows
2540 us to have public headers with Libxml2 stuff in them . It should also,
2541 eventually, make Libxml2 checks redundant in packages using YAZ, such
2544 --- 2.1.22 2006/06/15
2546 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2547 stored in uri, message and details.. Previously diagnostics were stored
2548 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2549 compatibility.. but he's probably the only one affected, so.
2551 Added support for CCL, compiled on the client side, in ZOOM-C. This
2552 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2553 input; the resulting query objects can be used for for searching with
2554 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2556 YAZ' configure searches for OpenSSL by default.
2558 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2559 SL_CTX_use_certificate_file. See
2560 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2561 for more info. Thanks to Ko van der Sloot.
2563 --- 2.1.20 2006/06/02
2565 Bug #600: SRU GET, POST support for yaz-client. Introduced
2566 command 'sru' which selects method SOAP/GET/POST.
2568 Allow missingValueAction to be specified for the sortspec string -
2569 function yaz_sort_spec. By default, the missing value action is null.
2570 Use ! to specify "abort". Use = followed by stringvalue to specify default
2573 Ensured that Present-handler (if defined) is called in GFS before any call to
2574 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2575 searchRetrieve requests.
2577 Documentation for YAZ is now based on the Docbook XML/XSLT using
2578 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2579 is no longer depending on jade/openjade or docbook-to-man scripts.
2580 PDF is no longer part of the distribution - but can optionally be
2581 made using DSSSL/jadetex or FOP.
2583 Added retrieval handling support in Generic Frontend Server to support
2584 conversion between MARC/XML as well as XSLTtransforms. See
2585 etc/yazgfs.xml for an example.
2587 Added Authentication support to Generic Frontend Server in SRU
2588 mode. Authentication using HTTP Basic is supported, as is the use
2589 of 'x-username' and 'x-password' parameters in the request itself.
2591 Added support for a new character set MARC8s identical to MARC8 except
2592 that it converts combined characters to single Unicode characters in the
2593 Latin-1 range (when possible).
2595 --- 2.1.18 2006/04/24
2597 ASN.1 compiler 0.4: generates brief Doxygen file header for
2598 generated .h/.c files.
2600 Utility yaz_iconv now supports conversion to MARC-8.
2602 New facilities for the MARC module. The reading - and writing of
2603 content are separate methods for the yaz_marc_t handle. The following
2604 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2605 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2606 format). Write functions have prefix yaz_marc_write_.. The existing
2607 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2608 available. Removed support for OAI-MARC and simplexml (not the
2609 simplexml from PHP5).
2611 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2612 to be returned for this connection.
2614 --- 2.1.16 2006/03/31
2616 Allow multiple languages and charsets to be specified with
2617 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2618 negcharset iso-8859-1,utf-8
2620 Translation of proximity nodes from CQL into PQF now works.
2622 Moved to automake 1.8, 1.9.
2624 Added function yaz_log_set_handler which allows a log handler to be
2625 installed. This handler will be called for all log messages. Output
2626 to file is also produced; but that can be disabled by passing NULL
2627 fname to yaz_log_init_file.
2629 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2631 For SRW (including GFS), accept application/soap+xml as content-type
2634 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2635 produces NO stylesheet reference even if a default stylesheet is specified
2638 --- 2.1.14 2006/03/14
2640 Updated Windows package to include yazd.dll + yazd.lib for the
2641 Development component.
2643 If the environment variable YAZ_LOG is set, then it is used as a
2644 string indicating the default level of logging to use if not
2645 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2646 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2647 used as before. So, for example, to omit warnings from YAZ logging,
2648 export YAZ_LOG=-warn
2650 cql_transform() now map structure and other attributes before indexes,
2651 so that index-specific structures and other attributes can override
2652 defaults. So now a combination of mapping specifications such as:
2654 index.dc.date = 1=date-modified 4=5
2655 does the right thing.
2657 cql_transform() now also respects the "always" mapping specification,
2658 which establishes an initial set of attributes to be used for all
2659 terms except where overridden by more specific attributes associated
2660 with the index, relation or modifier.
2662 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2663 which mode to use; one of "post", "get" or "soap" (SRW, default).
2665 Fixes for yaz_iconv routines: changed trie-based character set conversions
2666 to use only non-negative values for bit fields due to Sun's C compiler not
2667 supporting negative values.
2669 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2670 sequences where not read correctly. Fix by Rustam Usmanov.
2672 Updated win/makefile to use options, settings which makes things
2673 compile with VS C 2005.
2675 --- 2.1.12 2006/02/01
2677 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2679 In ZOOM socket code, use select instead of poll on MacOSX.
2681 ZOOM-C now support client-side compilation of CQL into RPN that is
2682 sent to the server, enabling CQL to be used against all Z39.50
2683 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2684 ZOOM_query object, and submit it using ZOOM_connection_search().
2685 The CQL-to-RPN translation uses a configuration file, the name of
2686 which must be specified in the Connection's "cqlfile" option.
2688 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2689 function, which takes as its start-term parameter a ZOOM_query object
2690 (which may have had either CQL or RPN set into it).
2693 --- 2.1.10 2005/11/29
2695 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2696 GFS to support this as well. Backend handler, bend_srw_update, does the
2697 update work. Code contributed by Ko van der Sloot.
2699 Allow retrieval of Search Result-1 information in ZOOM by the use of
2700 options that are attached to a result set. ZOOM documentation updated
2703 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2704 UTF-8 conversion. Patch by Raj Patel.
2706 Added option -m to GFS to control formatting of timestamps in log file.
2708 Added 'exit' as synonym for 'quit' in yaz-client
2710 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2711 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2712 for the new members. Patch by Ko van der Sloot.
2714 Added support for SRU POST. It is supported for content-type
2715 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2717 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2718 Instead make the library libyaz.la multi-threaded. Threading as a whole
2719 can still be disabled by configure option --disable-threads. Previosly,
2720 with older GLIBCs there were problems with MT libs under Apache. This
2721 has now been fixed a long time ago.
2723 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2726 CQL module modified to be case insensitive for relations/indexes/operations.
2728 Fixed bug in CQL transform code: incorrect value relationModifieder
2731 Added 'show all' command for yaz-client which retrieves all results
2734 Added new yaz-client, xmles, which takes a (private) OID and
2735 a document to be sent as an extended service request.
2737 Describe new yaz-client commands wait_response and set_auto_wait.
2739 Increase TCP/IP listener backlog from 3 (which I am guessing was
2740 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2741 that the socket will queue as many incoming connections as it's able
2742 to handle ongoing connections. In other words, it will never now
2743 refuse a connection that it would be able to handle merely because
2744 it's not got around to accepting() enough of the pending connections
2745 yet. This is the behaviour anyway under Linux, where the listen()
2746 argument is ignored; but not under BSD and on systems such as
2747 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2748 YAZ-based servers should now be uniform across operating systems in
2751 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2752 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2753 This allows yaz-marcdump to read large MARC batches (>2 GB).
2755 Modified all YAZ source files - except the source which is auto-generated
2756 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2759 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2760 corresponding to the existing *_setl() function. These allow option
2761 values containing arbitrary valuues.
2763 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2764 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2765 except that it returns an indicator of whether or not the sort
2766 criterion was accepted (0 for OK, -1 for invalid).
2768 --- 2.1.8 2005/06/07
2770 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2771 MARC output rather than returning "new" buffer.
2773 yaz-client warns about unknown init options.
2775 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2777 --- 2.1.6 2005/05/24
2779 Added support for SRW sort in Generic Frontend Server. Patch
2780 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2781 sortKeys - or NULL if none is provided.
2783 Fixed bug #307: It was impossible to specify indefinite/no timeout
2784 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2787 Added support for multiple languages and charsets to be specified in
2788 ZOOM. Each charset/language is separated by a blank. If negotiation is
2789 in effect in init-response, Option
2790 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2791 Code based on patch by Vasiliy Osadchuk.
2793 Fixed bug #306: infinite recursion that occurred when calling
2794 yaz_log_level_init as the first call (before other log level or
2797 Fixed bug in scan handling in front end server: if preferred-Position-In-
2798 Response was non-present, a NULL pointer referece was performed.
2800 --- 2.1.4 2005/04/26
2802 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2803 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2804 now defined for all those error codes. So instead of putting 109 in
2805 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2806 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2808 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2811 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2813 Program yaz-client now exits and produces an error message if multiple
2814 Z39.50 servers are specified on the command line (none or one allowed
2817 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2820 --- 2.1.2 2005/03/16
2822 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2824 Fixed bug #272: Preserve spacing for CCL terms.
2826 --- 2.1.0 2005/03/14
2828 Added support for virtual hosts and multiple backend servers for
2829 the YAZ frontend server. The configution is XML based and
2830 support specificition of CQL to RPN mappings and explain information.
2831 See section "Virtual Hosts" in the YAZ manual.
2833 Extended OPAC display utility. OPAC display utility renders
2834 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2835 to supplement yaz_marc_decode_wrbuf.
2837 Fixed a bug in MARC decoder that could caused it to crash for some
2838 invalid MARC records. More diagnostics and warnings where added in
2839 XML output (warnings, etc are stored in comments).
2841 --- 2.0.34 2005/02/08
2843 Fixes for UNIX domain sockets. Bug #261.
2845 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2847 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2848 Added yaz_marc_subfield_str which defines subfield lead string which is
2849 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2850 yaz_marc_endline_str which defines end of fields string used in
2851 YAZ_MARC_LINE format. Default string is newline.
2853 Experimental support for MarcXChange. This format can be produced
2854 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2855 http://www.bs.dk/standards/MarcXchange.xsd
2857 Added yaz-client commands scansize that sets maximum number of
2858 entries to be returned by scan.
2860 --- 2.0.32 2005/01/11
2862 Added support for SRW scan in yaz-client and Generic Frontend Server.
2864 * Added whereInList member to SRW Scan Term.
2866 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2868 Fixed NMEM system to return aligned blocks on the smallest boundaries
2869 that are suitably aligned for all possible types on the particular
2870 architecture YAZ is being built for.
2872 --- 2.0.30 2005/01/04
2874 Fixed numerious warnings that was issued with newer versions of GCC.
2876 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2877 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2880 Make YAZ Generic Frontend Server slightly faster.
2882 Enhance (and reduce) logging for Generic Frontend Server.
2884 Revert YAZ log system so that it flushes every write operation
2885 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2887 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2888 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2889 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2890 will effectively disable old definitions.
2892 --- 2.0.28 2004/11/09
2894 Added yaz_log_time_format which specifies log format using
2897 Added yaz_log_module_level which returns mask for a module. Value
2898 is non-zero mask a if module is enabled; zero if disabled.
2900 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2901 in include/yaz/cql.h.
2903 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2905 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2907 Fixed bug #172: RPM builds does not enable SSL.
2909 Doxyfile.in part of dist. Doxyfile generated by configure.
2911 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2912 are given and the corresponding component does not exist.
2914 Extend CCL documentation in YAZ reference. Describe r=r.
2916 --- 2.0.26 2004/10/01
2918 Fixed MARC->MARCXML conversion to properly deal with
2919 fields, subfields, indicators having non-ASCII characters.
2921 Fixed MARC->MARCXML conversion so that ASCII control characters
2922 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2925 Added YAZ GFS support for conversion from Z39.50 surrogate
2926 diagnostics to SRW surrogate diagnostics.
2928 Bug fix: YAZ GFS did not return schema in explainResponse.
2930 --- 2.0.25 2004/09/30
2932 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2933 now converts recordSchema to elementSetName as well as schema URI.
2935 Fixed bug in COMSTACK that prevented HTTP request packages from being
2938 --- 2.0.24 2004/09/29
2940 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2941 does not require white-space before and after the dash in a range, e.g.
2942 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2945 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2946 due to new GCC removing "redundant" code.
2948 Added yaz-client commands scanpos and scanstep that sets preferred
2949 position and step-size for scan.
2951 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2953 Added CCL utility ccl_qual_buf which parses one or more CCL
2954 spec lines in a buffer.
2956 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2957 of name and value - ignoring empty lines and comments.
2959 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2961 Added odr_get_element_path which returns current element path for an
2962 ODR handle. This utility is useful in error handling or user-defined
2965 Added ODR_PRINT utility odr_set_stream which is is a more generic
2966 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2967 to a write function and pointer to close function. The close function - if
2968 non-NULL - will be called during odr_destroy.
2970 Fixed bug in CCL parser where truncation char was not removed from
2971 right side when truncation=both was in effect.
2973 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2976 --- 2.0.23 2004/08/11
2978 Fix buffer overrun in CQL parser when dealing with proximity (%).
2980 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2981 to UTF-8/UCS conversion is now only based on codetables.xml.
2983 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2985 --- 2.0.22 2004/08/06
2987 Add support for more "commit changes" in ZOOM (uses Extended Services).
2989 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2992 Yet another small fix for configure of SSL.
2994 --- 2.0.21 2004/05/14
2996 Fix SSL libs for configure when --with-openssl=DIR is given.
2998 --- 2.0.20 2004/05/10
3000 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
3002 SSL comstack now uses yaz.pem certificate file on server side
3003 by default. Certificate filename can be configured by calling
3004 comstack function cs_set_ssl_certificate_file before cs_bind is used.
3006 Fix bug regarding multiple calls to ZOOM_connection_connect.
3008 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
3010 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
3011 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
3013 ZOOM now allows inspection of X509 peer certificate for verification.
3014 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
3016 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
3017 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
3018 as "modular" but it simplifies things.
3020 Added cs_get_peer_certificate to that returns peer X509 PEM.
3022 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
3023 NULL if SSL is unavailable.
3025 Documentation about MARC decoding tools.
3027 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
3029 --- 2.0.19 2004/03/30
3031 Rename CHANGELOG to NEWS to follow GNU style packing.
3033 Fix bug with missing initialization of member in init_diagnostics.
3034 This bug affects threaded version of GFS server.
3036 --- 2.0.18 2004/03/20
3038 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
3041 Ensure zlib.dll is packed with Windows install.
3043 --- 2.0.17 2004/03/17
3045 Fix encoding of xsd:string to use text instead of CDATA.
3047 Fix endless loop in CQL parser with unbalanced ".
3049 Use a more compact way to store MARC-8 conversion tables.
3051 --- 2.0.16 2004/03/16 Debian only
3053 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
3056 Update CQL parser to use new CQL 1.1 modifiers for booleans and
3061 --- 2.0.15 2004/03/01
3063 Another fix for decoding of XML packed records.
3065 --- 2.0.14 2004/02/25
3067 Fixes for Chunked encoding. White space not ignored after length spec.
3069 Update NS and use default NS for SRW diagnostic elements.
3071 --- 2.0.13 2004/02/23
3073 Implement ZOOM_resultset_cache_reset which resets record cache.
3075 Implement ZOOM_resultset_sort which sorts a result set.
3077 Implement chunked HTTP transfer.
3079 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
3081 --- 2.0.12 2004/02/16
3083 Added member 'schema' to bend_explain_rr structure so that backend
3084 can specify explain record identifier. Defaults to Zeerex 2.0.
3086 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
3088 --- 2.0.11 2004/02/16
3090 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
3093 Added init command for yaz-client which sends "extra" init request.
3095 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
3096 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
3098 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
3100 Make ZOOM error code for "invalid query".
3102 Fixed compilation for SSL which wasn't properly enabled for all platforms.
3104 --- 2.0.10 2004/02/05
3106 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
3109 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
3111 Added option -p <file> to make Generic Frontend Server to write PID file.
3113 Added option -D to put Generic Frontend Server in background on its own.
3115 Make ZOOM C recognize option "password". If unset, "pass" is used
3116 (for backwards compatibility).
3118 Fixed a bug in Generic Frontend Server that could make it crash if a
3119 client sets characterSetNegotation bit, but didn't pass negotiation stuff
3122 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
3123 Must be issued before open, in order to be in effect.
3125 --- 2.0.9-6 2004/01/12 Debian/Windows
3127 Make the SRU server more picky WRT unknown params, etc.
3129 Bug fix: ZOOM scan response didn't return displayTerm - when present.
3131 New YAZ client command, options, that sets Z39.50 options.
3133 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
3134 options from a string of tokens (one token for each option bit).
3136 Update SRW diagnostic code messages.
3138 --- 2.0.9-5 2004/01/07 Debian/Windows
3140 Handle user defined stylesheet for SRW/SRU.
3142 --- 2.0.9-4 2004/01/06 Debian/Windows
3144 Fix bug in decoding of Content-Length.
3146 --- 2.0.9-3 2004/01/06 Debian/Windows
3148 Fix a bug with decoding of XML packed records.
3150 --- 2.0.9-2 2004/01/05 Debian only
3152 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
3154 Fix bug in SRW/SRU diagnostics decoding.
3156 --- 2.0.9 2004/01/05
3158 Fixed bug in Generic Frontend Server which could drop records exceeding
3159 preferred message size. Reported and fixed by Irina Dijour.
3161 Fixed calculation of package size for structured records in Generic
3162 Frontend Server. Reported and fixed by Irina Dijour.
3164 Fixed namespace for SRW/SRU diagnostics.
3166 Fixed SEGV in yaz-client that occured for HTTP connection errors.
3168 --- 2.0.8 2003/12/22
3170 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
3171 this version is incompatible with version 1.0 and older YAZ SRW/SRU
3174 CQL changes to reflect recent changes to the specification:
3175 * Documentation talks about context sets instead of index sets.
3176 * Documentation talks about indexes instead of qualifiers.
3177 * The CQL-to-PQF transformer's configuration file now uses
3178 "index.set.name = <attributes>" instead of the old form
3179 "qualifier.set.name = <attributes>". (Both forms are still
3180 understood but the latter is deprecated.)
3181 * CQL terms with no explicit index specified are now interpreted as
3182 cql.serverChoice instead of srw.serverChoice (which of course
3183 behaves exactly the same.)
3185 --- 2.0.7 2003/12/16
3187 MARC conversion can now generate ISO2709 output in another
3188 character set. yaz-marcdump uses this facility if you invoke it
3191 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
3192 functions from there can be used from C++.
3194 --- 2.0.6 2003/12/04
3196 Frontend server now transfers memory from decoded packages to stream
3199 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
3200 references to show up.
3202 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
3203 the ZOOM Abstract API. The older names for the same options are still
3204 also supported for the benefit of old applications.
3206 ZOOM-C supports "implementationId" and "implementationVersion" options
3207 to go along with "implementationName". These allow the user code to
3208 specify identification strings to be sent to servers.
3209 Add OID for the new ExtLite attribute set.
3211 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
3212 as requested/supplid by Ere Maijala <ere@atp.fi>
3214 For generic frontend server, reverse the order of
3215 "toolkit-supplied / application-supplied" strings sent as implementationId,
3216 Name and Version. Also, remove the spaces around the slash. This brings
3217 the GFS in line with the behaviour of ZOOM-C on the client side.
3219 Add function ZOOM_scanset_display_term.
3221 yaz-client shows scan displayTerm if present.
3223 Utility yaz-iconv is now installed by default along with the man page
3226 Extend configure check for OpenSSL to use pkg-config where available (such
3229 Incorporate patch by Morten Bogeskov which allows a Unix file socket
3230 server to specify uid/gid/mask for socket using the format
3231 unix:[user=uid,][group=gid,][umask=mask,]file=path
3232 If file= is omitted the existing format is assumed, e.g.
3234 in which case the mask is 0666 (rw for everybody).
3236 Major restructure of YAZ source. All source in libyaz is in src directory.
3237 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
3238 util (utility programs such as ASN.1 compiler, yaz-marcdump).
3240 Added man page for utility yaz-marcdump (used to be called marcdump).
3241 yaz-marcdump is installed by 'make install'.
3243 Fixed a memory leak in Generic Frontend Server that occurred when decoding
3244 of incoming package failed.
3246 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
3248 Change prototype of odr_perror: add const to message string.
3250 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
3252 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
3253 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3254 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3255 DNS lookup. There should not be any compatibility problems with this
3256 assuming that blocking=1 or 0 is used.
3258 Fix bad reference in UNIX comstack in function cs_addrstr.
3260 Fix for compilation on AIX.
3262 The generic front-end server (server/seshigh.c) now supports returning
3263 Init diagnostics to the client in User-information-field, in
3264 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3267 --- 2.0.4 2003/09/04
3269 Allow any CQL relation (not just all,any,exact,scr).
3271 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3272 that features the same UI.
3274 Implemented command update0 in YAZ client which is equivalent to
3275 update but uses old of Ext Update ASN.1.
3277 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3278 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3279 Previously no OID was used for this info.
3281 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3282 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3283 returns 'malformed search term' otherwise.
3285 SortResponse member resultCount now set to NULL in sort handler of
3288 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3291 Add three new utility functions for translating OIDs between various
3292 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3293 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3294 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3295 char *oid_to_dotstring(const int *oid, char *oidbuf);
3296 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3298 Reverted modifications for ES Update definition for z_IU0Update
3299 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3300 is back to YAZ 2.0.2.
3302 String value attributes for CCL parser.
3304 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3305 which their FirstSearch server returns in Init responses, sometimes
3306 carrying useful diagnostic information when Init fails. This has the
3307 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3308 "z39.50/oclcui.asn", where its definition is somewhat different from
3309 what OCLC document on their web-site, as required to interoperate with
3312 Support for anonymous authentication in yaz-client. Use the command
3315 * Fix the OID of the Index Data-local "admin" Extended Service from
3316 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3317 the 1000, which indicates a locally-defined OID, was a mistake.
3319 --- 2.0.3 2003/06/20
3321 Fix CCL directive @case handling so that it affects string match for
3322 both CCL keywords and qualifiers.
3324 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3325 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3326 Decoder has been updated with ASN.1 changes as listed in
3327 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3328 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3329 z_IUUpdate, remains unchanged.
3331 ZOOM_record_get may now return a record in a specific character set.
3332 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3333 "from" is the character set of record as returned by target. "to" is
3334 the character set to be returned. If omitted, "to" is UTF-8.
3336 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3338 New ODR utility, odr_getelement, which returns name of element for
3339 which encoding/decoding failed.
3341 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3342 in cases where a required element was omitted.
3344 Bug fix: some MARC8 sequences were not converted.
3346 New ZOOM option "step" which specifies number of records to be
3347 retrieved in one chunk. Used in conjunction with "start" and "count".
3349 SRW support for yaz-client. Use scheme http: to use it, e.g.
3352 yaz-client no longer does (un)intelligent character set conversions
3353 by default. Can be enabled with charset and marc_charset commands.
3355 xmalloc trace fix for 64-bit systems such as DEC alpha.
3357 Solaris 2.6 compile fix.
3359 New function, cql_strerror() translates SRW error codes, as returned
3360 by cql_transform_error(), into human-readable English strings. Used
3361 in yaz-client diagnostics when appropriate.
3363 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3364 converts it into a type-1 query which is sent to the server. This
3365 makes CQL available for use with all Z-servers, as opposed to the tiny
3366 minority that can handle CQL queries themselves.
3368 --- 2.0.2 2003/04/28
3370 New Debian package layout similar to the Redhat Package layout.
3372 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3373 and search result respectively.
3375 --- 2.0.1 2003/04/25
3377 Redhat package is now several packages: libyaz (runtime libraries),
3378 libyaz-devel (development and documentation, and yaz (utility programs).
3379 Package spec file by Morten Bogeskov.
3381 New member 'schema' in struct bend_fetch_rr which the name of requested
3382 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3383 handler MAY set this to reflect the schema of the returned record.
3385 New member 'display_term' in struct scan_entry. GFS now sets member entries
3386 and allocates scan entries to be filled by user scan handler. In previous
3387 version, entries member was allocated by the scan handler. That still works,
3388 but the GFS will ignore member display_term - assuming it was NOT set by
3389 the handler. The fact that the GFS now allocates the entries both allows
3390 for new members and makes a scan handler easier to write.
3392 Fix CQL lex buffer overflow.
3394 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3395 SRU default recordPacking is string.
3397 SRU protocol support for frontend server.
3399 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3401 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3403 Added scan for the ZOOM shell (zoomsh).
3407 * String Identifers for Schemas (Amendment 5).
3408 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3409 Old definition for schema
3410 Odr_oid *schema; /* OPT */
3415 Z_InternationalString *uri;
3416 #define Z_Schema_oid 1
3417 #define Z_Schema_uri 2
3420 * resultCount parameter to Sort Response (Amendment 1).
3421 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3423 Support for SRW 1.0 over HTTP. This is an optional feature and
3424 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3427 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3428 on the same port. SRW SearchRetrieveRequests are mapped
3429 to bend_init,bend_search,bend_fetch,bend_close.
3431 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3433 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3434 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3436 ZOOM connections are SRW based if schem http is used for hostname
3437 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3438 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3440 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3441 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3442 distance=n, order=true/false, relation=le, prox unit=word. If
3443 n is omitted, distance 1 is used.
3445 Fixed problem with C compiler include path in wrong order.
3447 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3448 on Solaris. Patch from Ko van der Sloot.
3450 New MARC decode API. All new functions operate on a yaz_marc_t
3451 handle. The most important new functions are: yaz_marc_create,
3452 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3453 decode and destroy respectively. Decoder can produce formats
3454 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3455 include/yaz/marcdisp.h.
3457 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3458 to UTF-8, UCS-32, wchar_t or Latin-1.
3460 * Prototypes for yaz_iconv_-functions moved to separate header
3461 include/yaz/yaz-iconv.h.
3463 Make a few private functions 'static' in unix.c. This prevents
3464 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3466 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3467 are set when Init Response is received.
3469 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3470 but returns diagnostic set as well.
3472 New function yaz_strerror which is a portable wrapper for
3473 strerror/strerror_r/GetLastMessage.
3475 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3476 is returned for MARC. If type is "oai", then OAI MARC is returned.
3478 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3481 --- 1.9.2 2002/11/26
3483 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3485 Fix bad race conditions on SIGTERM and terminate gracefully in
3488 Move retrieval (data1) module to Zebra since nobody seems to be
3491 Add GRS-1 render for ZOOM using same format as yaz-client.
3493 --- 1.9.1 2002/10/05
3495 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3497 Fix broken ESpec handling in data1 module.
3499 SGML reader parses comments and makes them part of the data1 tree.
3501 Added several type casts so that YAZ compiles as C++ code.
3503 ZOOM didn't handle PDU encoding failures properly.
3505 Added more Bib-1 diagnostics (approved extensions).
3507 GNU configure: better check for iconv.
3509 More portable use of accept, getpeername. Check for socklen_t. Use
3510 int/size_t if socklen_t is not defined.
3514 PQF parser rejects bad queries - including those with extra
3515 characters in them. PQF parser used to silently ignore that.
3516 Cleaner API for PQF added, which allows you to get detailed
3517 error information for bad queries (see yaz/pquery.h).
3519 Fixed bug in ZOOM_record_get for type "database".
3521 Implemented mini iconv library supporting conversions between
3522 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3524 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3526 --- 1.8.9 2002/08/20
3528 Fixed ZOOM C record cache so that preferredRecordSyntax and
3529 elementSetName is used to check for already fetched records.
3531 --- 1.8.8 2002/08/02
3533 Added three members in bend_initrequest structure to facilitate
3534 character set negotiation.
3536 Fixed a bug in frontend server that could cause indefinite
3537 loops under rare conditions.
3539 Revised character set utilities (charneg.h) so that encoding
3540 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3542 For PQF, directive @term <type> sets term type for Scan/Search.
3543 Here <type> is general, string, numeric, null. The term type
3544 is inherited - just like @attr.
3546 New call odr_set_charset that sets character set conversion for
3547 international-strings on a ODR stream. Prototype is:
3548 int odr_set_charset(ODR o, const char *to, const char *from);
3549 The InternationalString is still represented as C string in YAZ
3550 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3551 won't). On the protocol level, you can use any encoding.
3553 Support for UNIX sockets in ZOOM.
3555 Solaris recv sometimes returns errno == ENOENT. It is treated as
3556 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3558 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3559 both client and server. Code by Morten Bogeskov.
3561 --- 1.8.7 2002/05/22
3563 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3564 that they can be used directly from Visual Basic. You must recompile
3565 your windows APP if you're using ZOOM.
3567 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3568 Commands "lang" and "charset" sets language and character set respectively.
3569 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3570 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3572 Attributes from multiple CCL fields may be OR'ed rather than merged
3573 using directive "@field or". Fields are still merged by default -
3574 equivalent to "@field merge".
3576 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3579 Fixed bug in zget for parameter ExtendedServicesResponse.
3583 --- 1.8.6 2002/03/25
3585 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3587 Client displays USR.1:SearchResult-1 (hits per term).
3589 Additional Search Info for search in Generic Frontend Server.
3591 Fixed CCL parsing of "field=s".
3593 WIN32 installer - using the excellent NSIS software from nullsoft.
3595 Fixed CCL parsing of "field = - <number>".
3597 Added function yaz_marc_decode that decodes MARC for line mode
3598 display or XML (similar to that used by JZKit).
3600 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3601 Z39.50. But ISO/ILL was, however.
3603 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3604 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3606 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3607 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3609 --- 1.8.5 2002/02/03
3611 New YAZ client features: Command completion and new commands:
3612 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3613 Code provided by Jacob Poulsen.
3615 New call oid_trav, that visits all registered OIDs via callback.
3617 Function ZOOM_record_get now returns const char pointer rather than
3618 void pointer. It saves a lot of type casts.
3620 For YAZ client, command "auth" now allows you to set authentication
3621 in IdPass style. It is enabled when three tokens are given - order
3622 is user, group and password.
3624 Fix memory leaks in MARC record handling for ZOOM.
3626 New option for YAZ client, -k <kilobytes> that sets
3627 maximum record size. Similar to -k option for generic frontend
3628 server and yaz-ztest.
3630 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3632 Prefix query parser reports "fail" when bad attribute set is given.
3634 Fix in MARC decoder. Proximity logging. Fix for attribute set
3635 in scan handler for server. Patches by Shigeru Ishida.
3637 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3640 Configure option --with-openssl=<dir> now works when a directory is
3641 specified. Patch provided by Morten Bogeskov.
3643 New option for YAZ client, -u <auth>, that sets authentication.
3645 ZOOM fix: error information was sometimes "missing", since error
3646 was cleared/reset too when it shouldn't.
3648 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3650 --- 1.8.4 2002/01/04
3652 Scan for ZOOM API. New object ZOOM_scanset. New functions
3653 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3654 ZOOM_scanset_destroy.
3656 New ZOOM function, ZOOM_connection_last_event, that returns type
3657 of last event (such as "receive data", "send data", "apdu received",
3660 New ZOOM option, schema, that specifies schema for retrieval.
3662 New CCL feature. Qualifiers can be aliases for one or more
3663 other qualifiers (if more than one is given, OR is used).
3665 ZOOM uses named result sets if target supports it.
3667 Two new YAZ client commands: . (dot, which sources a script of YAZ
3668 client commands), and ! (to execute shell command.). Implemented
3671 Working on Debian packages.
3673 --- 1.8.3 2001/11/19
3675 YAZ client enables named result sets only if target supports it.
3677 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3679 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3680 with key="host" to get same result.
3682 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3683 Function Z3950_resultset_record(s) returns references to records
3684 "owned" by resultset. To become owner use Z3950_record_clone.
3686 Function z_ext_record handles Extended Services. Thanks to
3689 --- 1.8.2 2001/11/12
3691 CCL Parser fix: ignore token comma when dealing with and-lists.
3693 Documentation updates for COMSTACK.
3695 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3696 Changed prototype Z3950_records. For some functions, int parameters
3697 were changed to size_t.
3699 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3702 New MARC decode/display function, marc_display_exl, which properly rejects
3703 non-ISO2709 records. YAZ client uses it.
3705 --- 1.8.1 2001/10/29
3707 Fix bug: local attribute set wasn't set correctly in PQF strings.
3711 * Old Z39.50 codecs no longer supported.
3713 Added ZOOM C binding. See http://zoom.z3950.org/
3715 Renamed states for COMSTACKs to avoid confusion with events.
3717 Implemented cs_look and proper cs_rcvconnect.
3719 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3721 Configure detects POSIX threads on OpenBSD.
3723 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3724 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3726 When error is returned from present handler, non-surrogate diagnostic
3727 is returned in present response (and fetch handler is no longer called).
3729 * Minor adjustments to pquery parser (PQF). Token characters may be
3730 escaped by using backslash (C-style).
3732 PQF parser allows string attribute values to be specified. For @attr,
3733 non-numeric characters after the equal-sign are treated as strings
3734 (e.g. @attr 9=title).
3736 CCL trunction character may be defined (@truncation in file)
3738 * function zget_ExtendedServicesRequest sets waitAction to
3739 waitIfPossible (was wait).
3741 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3744 CCL operator names may be set in field definition files (CCL_bibset).
3745 See ccl/bib1 for an example.
3747 Fixes in ASN.1 compiler for C++ compatibility.
3749 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3750 and "op_or" to avoid conflict with C++.
3752 Fixed problem with GNU readline detection on Redhat 7.0.
3754 Added step-size for Scan backend handler.
3756 Fixed bug that made the frontend server crash when no attribute
3757 set was specified for scan.
3759 Front-end server automatically switches to original working directory
3760 when installed as an NT service. Previously -w had to be specified to
3763 Added extended attributes for retrieval module (data1), so that data1
3764 records carry d1_readXML/SGML attributes. d1_read also supports
3765 null-data rules ( <tag/>)
3767 On UNIX when POSIX threads are available, a separate library libyazthread
3768 is created. Programmers should link with that library and the yaz library
3769 when using threads. The reason for the split was that some applications
3770 on Linux, such as Apache, doesn't work well when using shared objects that
3773 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3774 (or any frontend server) in SSL mode by specifying ssl: followed by
3775 address. Only tested on UNIX.
3777 Added feature for CCL module. Virtual structure s=al or s=ol generates
3778 and-list and or-list respectively instead of phrase search.
3782 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3783 log_mask_str. This was done to avoid name conflicts with other libraries
3784 (such as other PHP extensions).
3786 Added raw OID member for preferred record syntax (request_format_raw)
3787 and returned record syntax (output_format_raw) for backend fetch method.
3789 Config file yaz-config now accepts options so that it returns specific
3790 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3792 Shared library support for UNIX using GNU libtool.
3794 * Modified backend interface. Request/Response struct's replaced by
3795 one read/write C struct. For example bend_fetchrequest and
3796 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3797 Every handler - even search has to be registered in bend_init
3798 handler. This means that the YAZ library no longer refers to
3799 external functions and it makes it possible to make the whole
3800 thing a single DLL/SO.
3802 Added Segment handler for backend server.
3804 Added Zmbol/Zebra administrative functions to YAZ client.
3806 Threaded frontend server on UNIX (when POSIX Threads are available).
3807 Starting the server with option -T enables multi-threading.
3811 Added configure option --enable-comp/disable-comp to control use
3812 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3813 located in sub directory asn.
3815 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3816 in ${exec_prefix}/bin along with the other programs yaz-client and
3819 GNU automake used to maintain makefiles.
3821 Added several OID's.
3823 Changed retrieval module so that we can load records with no abstract
3824 syntax defined. Tagpaths in these records are fully composed of string
3827 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3831 On UNIX, the generated makefile now supports a proper 'make install'.
3832 The prefix can be set via GNU configure to set the install location
3833 (default is /usr/local).
3835 * YAZ programs client and ztest were renamed to yaz-client and
3836 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3837 locations, such as /usr/bin,/usr/local/bin,etc.
3839 * YAZ Header files were moved from include to include/yaz. YAZ Header
3840 files are referred to as include <yaz/log.h> rather than <log.h>.
3841 The YAZ include path (-I ..) is therefore the same as before. Programmers
3842 should update their #include statements or use -Ipath/include/yaz
3843 instead. The main motivation for doing this change is that YAZ header files
3844 can be installed in "standard" locations /usr/include,/usr/local/include
3845 without introducing conflicts, since ALL YAZ header files are stored
3846 in subdirectory yaz (under /usr/include for example).
3848 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3849 rather than project/workspace files. We switched because project files
3850 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3853 Changed name of logging function, logf, to yaz_log, to prevent name
3854 clash with some math-log functions. The YAZ header log.h defines logf
3855 to yaz_log (#define) so there should be no incompatibilities by this
3858 Added bend_start/bend_stop handlers for server. These handler are
3859 called on start/stop of server. For windows they are called whenever
3860 a service is started/stopped.
3862 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3863 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3864 in util/yc.tcl. The auto-generated C code structures are, in a few
3865 cases, incompatible with the old decoders. There are differences in the
3866 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3867 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3868 The preprocessor variable ASN_COMPILED is defined when the compiled
3869 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3870 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3871 wish to use the old encoders/decoders you can specify --disable-yc
3874 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3875 version so that it supports both new - and old version of DB Update
3877 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3878 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3879 change. The name parameter can be set to 0 in which no name is specified
3880 for the construction. The macros odr_implicit and odr_explicit sets name
3881 parameter to zero for the construction involved. New macros
3882 odr_implicit_tag and odr_explicit_tag are similar to the others,
3883 except that a name parameter is added. For programmers' that don't use
3884 ODR they probably only need to change the call to z_APDU and z_External.
3886 Added access control facility by interfacing the TCP wrapper library.
3887 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3888 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3889 name of the daemon and enables the access control as specified in
3890 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3892 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3893 den Dool <H.M.vdnDool@kub.nl>.
3895 Added reference ID parameter to most functions in server API - refer
3896 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3898 Changed name of ccl library to libccl.a (was ccl.a).
3900 Fixed bug in decoder for Explain (Category TargetInfo).
3902 Added support for GNU readline in client. Thanks to Jacob Poulsen
3903 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3905 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3906 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3907 IMPLEMENTATION! This change was made to the development version before
3908 the ZIG decided to retract the amendment. If any users MUST be
3909 compatible with the original Update definition, PLEASE CONTACT US, and
3910 we will include a separate definition corresponding to the old Update
3911 ES. Note that because of the change to the ASN.1 of the
3912 TaskPackageRecordStructure we cannot define a single structure that
3913 will support both versions.
3915 * Added const modifier to buffer parameter for some ODR/BER encoding
3916 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3917 completeWAIS, odr_dumpBER.
3919 Fixed bug in client.c which caused a crash when a scanResponse didn't
3920 contain positionOfTerm.
3922 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3923 * will cause an error in a client if a non-YAZ target sends both a
3924 * list of Scan entries and non-surrogate diagnostics.
3926 Retrieval module enhancements. Tag sets may be typed in the reference
3927 to it. From the .abs-file the "tagset" directive takes a third optional
3928 integer type for the tag set referenced. From a .tag-file the "include"
3929 directive takes a third optional type as well. The old "type" directive
3930 in the tag set itself is still recognized but acts as the default type
3933 Backend interface change. Individual Scan terms returned from bend_scan
3934 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3935 in include/backend.h.
3937 Retrieval module enhancements. Multiple tag sets and attribute sets may
3938 be specified in abstract syntax specs. Revised the error/warning for
3939 logging messages reported by the retrieval module when reading the
3942 Object Identifier system (oid_..) changed. The API is backwards
3943 compatible but the oid-routines now allocates new OID's when needed.
3944 Raw OID's may be specified in oid_getvalbyname.
3946 YAZ now uses GNU configure to generate Makefile(s).
3948 * Minor changes in some of the member names of DeleteResultSetRequest and
3949 DeleteResultSetResponse. See include/proto.h.
3951 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3952 and added member 'languages' in TargetInfo (which was missing).
3954 Changed the way attribute sets are handled in the retrieval
3955 module. These are now cached, just like the abstract syntaxes
3958 Changed YAZ so that it links with compiled ASN.1.
3960 Added Explain-schema definitions and mapping routines. The following
3961 Explain categories have been implemented: AttributeDetails,
3962 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3964 Fixed minor bug in Windows version of Server Library.
3966 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3968 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3970 Added EXTERNAL: UNIverse Resource Report (non-standard).
3972 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3973 ENUMERATED and SET OF.
3975 * Added 'const' to some of the char pointer arguments for the
3976 functions, data1_read_node, data1_getelementbytagname,
3977 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3980 Fixed bug in data1_insert_taggeddata - the last_child member of
3981 parent wasn't initialised.
3983 * Changed data1_read_record and data1_read_node so that the supplied
3984 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3985 doesn't refer to any parts of the "SGML"-buffer.
3987 Fixed bug in server library (Windows version of statserv_remove).
3989 * Changed code so that it compiles as C++. The type definition
3990 of Odr_fun which is a member of Odr_arm was changed. The result is,
3991 that an explicit typecast is needed for the fun pointer when
3992 using Odr_arm - as in:
3993 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3995 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3997 Implemented the new structured date and time definition as approved
3998 by the ZIG. Added schemaId element to the specificTag in Espec-1
3999 (also approved at the last ZIG). Thanks to RVDM.
4001 Added some Object identifiers (RVDM).
4003 Changed the Update Extended Service (RVDM).
4005 Added command "refid" to client which specifies referenceId for
4006 the following requests.
4008 Implemented extended service handling for server. See ztest.c
4009 for an example as well as backend.h. New handlers are registerd
4010 in the Init handler.
4012 * Changed interface for sort in server.
4014 Added new members to statserv_options_block. It allows a server
4015 to read options from another source than just the command line. Thanks
4016 to Charles Woodfield.
4018 * Changed definition of Z_Triple in file prt-grs.h - member boolean
4019 renamed to zboolean. Some C++ compilers complained about the name.
4021 Minor changes to gils.abs. Added index 's' (sort) on title
4022 and date/time-last-modified.
4024 --- 1.4pl2 1998/1/30
4026 Fixed bug in server library regarding inetd mode (-i). This bug
4027 was introduced by release 1.4.
4029 --- 1.4pl1 1998/1/29
4031 Added sort facility in client and backend server interface.
4033 Fixed problem with dependencies in Makefile(s).
4035 Fixed bugs for encoders/decoders of extended services and
4038 Implemented sub-tree feature for schemas. Sub-trees are
4039 referenced in *.abs-files. See explain.abs for an example
4040 of the use of this feature.
4042 Modified bib1.att; local attributes for ANY didn't include
4043 ANY itself (only affects use of the retrieval module).
4045 Fixed bug in plain SGML reader in function data1_read_node:
4046 tags with prefix "var" was incorrectly interpreted as variants.
4048 Added feature "sub-schemas" to enable references to - and definitions
4049 of - group of elements.
4051 * Removed member parent from type data1_element (in data1.h).
4053 Implemented function odr_nullval() that returns the value of
4056 * Removed member num_children from data1_node (in data1.h).
4058 Made NT service interface part of the server library. The
4059 function statserv_main uses the NT service when required and
4060 calls the statserv_start / statserv_close routines.
4062 Routine zget_SearchRequest and zget_PresentRequest fills
4063 resultSetName/Id member with "default" instead of "Default".
4065 Fixed memory leak in server. Request queue member wasn't freed.
4067 Fixed nmem_exit so that memory is freed.
4071 Revised the CCL parser utility to be thread safe.
4073 Added function, oid_ent_to_oid, to replace the function
4074 oid_getoidbyent, which is not thread safe.
4076 * Added nmem_init and nmem_exit to initialize and release
4077 NMEM resources. Function nmem_init should be called once in the
4078 initial thread before NMEM/ODR is used. statserv.c and client.c
4079 have been changed accordingly. The change was necessary to make
4080 NMEM thread safe. The NMEM memory pool is shared amongst threads
4081 in a process. Unix-based applications will still work fine without
4084 Added NT Services interface for the the Z39.50 (statserv) Server.
4085 Refer to the ztest.c source on the usage.
4087 Windows 95/NT port using MSVC5.0. Project files are included in the
4090 * Defined new 'global' handle for the retrieval (data1) system. The
4091 new handled, data1_handle, describes the state of the data1 system.
4092 This handle is passed as first argument to virtually all
4093 data1 related routines. The functions data1_create and data1_destroy
4094 creates and destroys a data1 handle respectively.
4096 Added ODR encode stream member to all backend request structures
4097 init, search, scan etc. This stream should be used to allocate all
4098 memory used for the response when thread safe operation is needed.
4100 Changed the comstack utility, cs_addstr, to be thread safe. The
4101 returned hostname string returned by the function is now part the
4104 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
4105 function. The cs_straddr takes a COMSTACK handle as argument, so this
4106 function must be used after cs_create and before bind/connect.
4107 This function is thread safe.
4109 Moved test server to 'ztest' directory - generic server code still
4110 in 'server' directory.
4112 Made prefix query (pquery.c) utility thread safe.
4114 Added new function modifier YAZ_EXPORT to 'export' public DLL
4115 functions when using windows (see include/yconfig.h).
4117 Added definitions to the OID database (util/oid.c) (RVDM).
4119 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
4121 Added call to ccl_rpn_delete in client program.
4123 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
4124 release of RPN structure.
4126 Added support for C++, headers uses extern "C" for public definitions.
4127 With input from RVDM.
4129 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
4130 Thanks to Ronald van der Meer (RVDM).
4132 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
4134 Added support for private extensions to the OID database
4135 (oid_setprivateoids()). Thanks to RVDM.
4137 Added optional, physical ANY (key replication)
4139 Fixed null-reference problem in GRS-1 output filter.
4141 Proximity operator added to Prefix Query Format (PQF).
4143 In test client command "base" accepts multiple databases.
4145 Fixed bug in cs_close stack that caused trouble with WINSOCK.
4149 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4151 Smallish bug-fixes in the new encoders/decoders (explain).
4153 Bug fixed in DeleteRequest.
4155 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
4157 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4159 Added SOIF syntax (using private OID for now) to retrieval module and client.
4161 Added Update extended service.
4163 Added SearchResult-1 additional info structure.
4165 Added optional CCL (ISO8777) interpreter as separate module. Available
4168 --- 1.2 1996/6/10 (1st anniversary release)
4170 Added Summary record syntax. Lightly tested.
4172 Added OPAC record syntax. Untested.
4174 Added ResourceReport service encoders/decoders. Untested.
4176 Fixed bug in z_Unit - wrong tagging on unitSystem.
4178 Fixed bug in the DiagRecs decoder.
4180 Added options for max PDU size and session timeout to frontend-server.
4182 Added documentation of query-language parsers and other supporting utilities.
4184 [frontend-server] Added Attribute set to the bend_scanrequest API.
4186 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
4187 surrogate diagnostics were generated.
4189 [retrieval] Allow multiple local values for attribute.
4191 [retrieval] Allow multiple attributes per element in .abs files. index type.
4193 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
4195 --- 1.1pl2 1996/4/10
4197 Minor changes, mostly specific to Zebra's requirements (retrieval)
4201 Repaired bug in frontend server when running multiple listening
4202 endpoints in dynamic mode.
4204 z_External() now won't break if a known, ASN.1 value comes encapsulated
4205 in an octet-string. The value will pass through unmodified in an Odr_oct.
4207 Added a bit of code to the demo client to decode & display
4208 ASN.1-structured records represented in the octet-aligned branch of
4209 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
4211 Added z_ext_getentbyref() to the ASN module. Doc updated.
4213 * Completed the SCAN definition in the ASN module. This may break SCAN
4214 code based on older YAZ-versions at compile-time. The fix is easy -
4217 * Added 'displayTerm' and OtherInformation to the TermInfo structure
4218 under the SCAN definition. Remember to initialize this, server-people.
4220 Comstack should now support the WAIS protocol in TCP/IP mode. Note
4221 that this does not extend to ODR and ASN.
4223 Comstack allows insertion of established socket (primarily for
4224 inetd-operation of servers). Doc updated.
4226 Front-end server can now start from the inetd in TCP mode. Doc
4229 --- 1.0pl4 1996/1/24
4233 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
4234 the rank and record number.
4236 Adjustments to the frontend server.
4238 Fixed diagnostic BER dumper. It ignored the file argument.
4242 Various changes to retrieval module.
4244 Changed the union discriminators of the protocol files from enums to
4245 ints paired with #defines.
4247 *Changed oident.class to oident.oclass to avoid a reserved word in C++
4250 *Changed operator in the RPN structure to 'roperator', again to avoid a
4253 Fixed problems in Explain decoders/encoders.
4255 --- 1.0pl2 1995/12/6
4257 Memory bug in log module fixed.
4259 --- 1.0pl1 1995/12/5
4261 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4263 Bug in Explain DatabaseInfo module fixed.
4265 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4269 The shift to v1.0 signals that we now consider the *core* functionality
4270 of YAZ reasonably stable (the core being more or less equivalent to
4271 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4272 tested (Explain not at all - though that will happen soonish).
4274 Minor changes to code to support Windows port.
4276 Various minor changes after we're getting to use GRS-1 & co. more.
4278 Added Espec-1 format.
4280 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4281 of the protocol and it cannot be selected when encoding (maps into 'string'
4282 when decoding). Needed to talk to some servers.
4284 Demo client can request simple element set names.
4286 Added Diagnostic Format encoders/decoders.
4288 Added simple Close handling to frontend server (no hooks for resource
4289 reporting yet), and demonstration client.
4291 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4293 --- 1.0b3 1995/08/24
4295 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4296 handled incorrectly when records were requested in the searchResponse. This
4297 will only affect you if you use the frontend-server.
4299 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4300 Test-client will ask for and print GRS1. Ztest will return dummy records
4303 Added Explain encoders/decoders to the service-level API. Untested.
4305 Added Extended Services: Item Order encoders and decoders to the Service-
4306 level API. Untested. We could use a recent copy of the pertinent bits
4307 of the ILL protocol to add those bits.
4309 Added diagnostic format 1 encoders/decoders to the service-level API.
4312 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4313 odr_cons.c, which causes a more correct output.
4315 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4316 was always set to 0 when no records were requested in the searchRequest.
4318 * Added better external-handling. This shouldn't harm old code that
4319 *encodes* externals. It can break code that looks for a
4320 'single-ASN1-type' representation, since those types that are known
4321 are now decoded immediately. Look at the SUTRS sample code in
4322 seshigh.c and client.c. Documentation updated.
4324 Handling of structured records in bend_fetchresponse. Length -1 marks
4325 structured record, type is deduced from format field.
4327 --- 1.0b2 1995/06/27
4328 Fairly quick maintenance release to add SUTRS support.
4330 Fixed handling of SUTRS records in the demonstration client.
4332 * Added format field to the bend_fetchrequest and bend_fetchresponce
4333 structures of the backend API (frontend server). When the record is
4334 returned, the value of the format field is mapped to an OID. The
4335 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4336 of the record. The special value VAL_NONE in the bend_request means
4337 that no specific format was requested by the client. Documentation
4338 updated accordingly. Test server (ztest) will return a fixed dummy
4339 SUTRS record if your client requests SUTRS.
4341 Documentation updated accordingly.
4343 You can now set external libraries and RANLIB support in the top-level
4347 First public release.
