3 Extend get_org_info (snippets) to return original string YAZ-836
4 Two new functions have appeared: icu_chain_get_org_info2 and
5 icu_iter_get_org_info2 with a 4th parameter being a pointer
6 to the original string.
8 Fix tcpip.c compilation failure on VC9 YAZ-835
10 Fix icu_iter_get_norm returns invalid size for some input YAZ-834
11 The icu_iter_get_org_info returns information based on string
12 as it appears on tokenize step.
16 Deal with excess bytes in HTTP response for keepalive YAZ-830
18 Refactor ssl_put and tcpip_put to one function YAZ-832
20 Refactor ssl_get and tcpip_get to one function YAZ-831
22 Fix SEGV yaz-client for HTTP decoding error YAZ-829
24 Fix buffer overflow in cmd_elements in yaz-client YAZ-828
28 Fix test_sru.sh fails in pazpar2 YAZ-826
29 Unfortunately a regression occurred with YAZ 5.10.0 that would make
30 Pazpar2 fail for HTTP connections.
34 Use CONNECT for SSL backends and for Z39.50 thru HTTP proxy YAZ-825
35 Introduce cs_create_host2 which returns if connection should be
36 proxy aware (HTTP:absoluteUri or Z39.50 proxy:vhost in init).. For CONNECT,
37 the connection is NOT proxy aware (no absoluteUri and no Z39.50 vhost).
39 Fix http proxy fails with yaz-client YAZ-824
43 Fix 0 ptr reference for OPAC records from XML YAZ-822
47 Extend yaz daemon facility to assist int log rotation YAZ-818 YAZ-819
51 record conv: 'select' return org record if no x-path match YAZ-814
53 retrieval: pick matched element-set rule YAZ-813
55 Fix crash in record conv rule 'select' YAZ-812
59 record_conv: selection by X-Path YAZ-811
60 That's a new step in record conversion system (<select path=".."/>)
62 Document record render parameters for ZOOM - including base64
66 Fix application/x-www-form-urlencoded + empty YAZ-810
67 A SEGV occurred if Content-Type was "application/x-www-form-urlencoded"
68 and empty content was supplied.
70 Fix yaz-iconv man page for typos and incorrect example. YAZ-809
72 Fail hard if Bison is not found and is needed YAZ-808
76 Enable YAZ backtrace for programs YAZ-802
78 Update NMAKE makefile to use Visual Studio 2013 along with ICU 54.1,
79 Libxml2 2.9.2, Libxslt 1.1.28.
81 Fix daemon: parent process stops before child YAZ-806
82 Try to fix the situation where parent process stops before
83 child has acknowledged it .. SIGUSR2 back!
85 daemon: log message when keepalive stops.
89 Fix yaz-marcdump segfault YAZ-801. Problem in YAZ 5.6.0/5.7.0 and
90 would make yaz-marcdump crash when from-character set was issued.
94 Dump backtrace in case of SIGABRT, SIGSEGV YAZ-787
95 New function yaz_enable_panic_backtrace which enables backtrace
96 handler for current process. The handler will call backtrace always,
97 then gdb to provide as much detail as possible.
101 When marc-8 charset is specified when decoding MARC records, yaz-marcdump
102 and ZOOM record render will inspect leader 9 and switch to UTF-8
103 (Unicode) if that holds 'a'. This changes behavior, but is considered
104 safe because only MARC21 with leader 9='a' are Unicode. YAZ-800
106 Fix cs_put may reconnect if send fails. YAZ-798
110 Fix cannot build YAZ on jessie : libgnutls-dev is gone YAZ-797
114 Extended comstack with outgoing IP YAZ-795.
115 For cs_create_host + cs_create_host_proxy the vhost may be followed
116 by a outgoing host/IP. Separator is blank.
120 Add YAZ_EXPORT to cql_transform_r fixes YAZ-793 . This issue fixes
121 linker error with yazpp on Windows.
125 Fix uri array may overflow in yaz_solr_encode_request YAZ-775
127 Fix PQF to Solr conversion may produce invalid Solr query YAZ-792
129 0 ptr reference in handling Solr response with error YAZ-791
131 Fix annoying warning about wrbuf_putc on newer GCC YAZ-789
133 Fix documentation about --installa option YAZ-788
137 daemon: properly report when receiving SIGUSR2 from child YAZ-785
141 xmalloc: throw assert for clearly invalid calls to malloc and
142 improve diagnostics YAZ-783 YAZ-784
146 Stop building debs for Ubuntu raring, quantal, oneiric.
148 CCL YAZ-781: for multiple use attributes in a specification the
149 generated RPN will perform @or on each term.
150 For spec: term u=31 u=1016
151 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
153 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
155 CCL YAZ-779: combo qualifier should allow for forward references
157 Fix buildconf.sh, automake too old on centos5 YAZ-778
158 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
159 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
160 accepts it without a warning.
164 GFS: client_query_charset conversion YAZ-777
165 This is a feature for Z39.50 clients that sends queries that are not
166 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
167 encoding given to UTF-8.
169 Echoed SRU arguments support YAZ-776
170 This is achieved with new function yaz_srw_get_pdu_e.
172 ZOOM: expire times set for redis/memcached YAZ-772
173 For both redis and memcached option --expire=seconds sets expire
174 time for a result-set/search. Default time is 600 seconds (10 minutes).
178 No [rest of output is omitted] limit for yaz_log YAZ-774
180 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
182 For ICU testing, pass -o to yaz-icu. This will test the
183 icu_iter_get_org_info function.
185 Fix null ptr reference for freeReplyObject YAZ-773
189 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
191 RPM: do not build with libmemcached support. The libmemcached library
192 on CentOS 5/6 does not work reliably for us (redis to the rescue).
194 configure: only allow libmemcached version 0.40 or later. That's the version
195 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
196 that's not an option, consider redis.
200 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
202 Fix zoom+memcached: present request out of range YAZ-767
206 CCL: add new qualifier r=omiteq which will omit relation=equals
207 for ordered relations. This should be used in combination with either
210 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
212 Solr: simplify yaz_solr_decode_response
214 Solr: use different local var for string manipulation
216 Solr: Get rid of hardcoded limit of extra_args
218 Solr: encode lucene query type YAZ-736
219 Make sure the queries are treated as traditional "lucene", because that's
222 Fix ZOOM HTTP redirect failing on Windows+Solaris YAZ-755
226 Build packages for Ubuntu Trusty Tahr 14.04 LTS
228 wrbuf_cstr: fix off by one error.
230 wrbuf_buf: make it always return non-NULL
231 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
235 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
237 zoomsh: offer option -a apdulog
238 As we're used to from yaz-client and GFS based servers.
240 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
241 existing setting apdulog takes effect.
243 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
248 Add re-entrant CQL/Solr/RPN query conversion functions.
249 The re-entrant functions are: cql_transform_r,
250 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
251 These have same functionality as cql_transform,
252 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
253 return the additional infomration as WRBUF to make them re-entrant.
255 Remove CQL to Solr conversion and base solr_transform_t on
256 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
257 data structure as cql_transform_t.
259 cql2pqf utility allows RPN to Solr conversion
261 Fix assert in ZOOM when http connect fails YAZ-757
263 --- 5.0.22 2014/04/09
265 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
267 wrbuf_cstr: make it thread safe YAZ-753
269 yaz_log_init_file may take fd=<no> to open log file at the FD given.
271 --- 5.0.21 2014/03/21
273 Offer new utility function zget_AttributeList_use_string.
275 New conversion step, solrmarc, for record conversion module.
277 --- 5.0.20 2014/03/13
279 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
280 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
283 --- 5.0.19 2014/03/10
285 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
286 The standalone ZOOM sort was completely broken since 5.0.13.
288 ZOOM: generate event Connect rather than None for partial connect
289 (in fact getaddrinfo resolving).
291 ZOOM: only supply clientIP for InitRequest. Rather than for all
294 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
296 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
297 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
298 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
300 New "Facets" section in the documentation.
302 --- 5.0.18 2014/02/27
304 Call exsltRegisterAll in yaz_init_globals, so that all applications
305 using YAZ will have EXSLT things enabled.
307 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
309 Update various URLs to the re-organized SRU pages at LoC.
311 --- 5.0.17 2014/02/26
313 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
314 introduced in 5.0.12.
316 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
317 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
318 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
321 --- 5.0.16 2014/02/25
323 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
325 --- 5.0.15 2014/02/24
327 Fix gcrypt not properly initialized YAZ-740.
329 --- 5.0.14 2014/02/19
331 Describe memcached option for ZOOM.
333 ZOOM: throw present request out of range again YAZ-739
334 Was removed in YAZ 5.0.13.
336 --- 5.0.13 2014/02/18
338 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
339 with localtime_r when threads + fork is used (such as Metaproxy).
341 yaz-config: quote some RHS values (that might include blanks)
343 zoomsh: shows SearchResult-1
345 zoomsh: sortby command
347 zoomsh: use proper list of connections and result sets YAZ-725
349 Avoid yaz_log in sigterm handler for GFS YAZ-737
350 Logging is still performed, but outside sig handler.
352 New ZOOM C feature: result-set caching with memcached. Example:
353 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
355 Remove SSL via OpenSSL support YAZ-732
356 Also deprecate two functions from comstack that aren't working with
357 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
359 Revert "Bison: use %name-prefix directive rather than -p option"
361 --- 5.0.12 2014/01/22
363 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
365 SRU GET/Solr base URLs may hold additional ?args YAZ-729
366 ZOOM option extraArgs already does this, though. It seems useful
367 when dealing with Solr targets to limit by filter, eg.
368 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
370 Remove #fragment for HTTP request encoding YAZ-730
372 Doc: Update list of DLLs/LIBs
374 Doc: update href link to Unix utils and Git.
376 --- 5.0.11 2014/01/15
378 ZOOM: fix "lost connection" problem with servers that uses both squid
379 and another proxy behind it that returns Location headers with relative
382 zoomsh: do not use readline for stdin (no tty) YAZ-724
383 Just use fgets in that case. If the user hits Ctrl-D a new-line
386 zoomsh: empty command ignored YAZ-723
387 rather than performing exit of zoomsh.
389 yaz-url utility offers option -v to enable verbose mode.
391 yaz_url uses yaz_check_location and offers verbose mode.
393 Add new function yaz_check_location.
394 This function gets an absolute URI from Location (HTTP redirect).
396 cookie API: introduce yaz_cookies_reset
398 Update cql.y for newer bison YAZ-720
399 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
400 longer supported. Instead one must use %lex-param and %parse-param .
402 --- 5.0.10 2014/01/09
404 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
407 rpn2solr: support truncation left(2), left&right(3) YAZ-718
409 Mention SRU version 2.0 in yaz-client man page.
413 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
418 Make cs_parse_host public.A
420 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
421 introduced in YAZ 5.0.6.
425 Fix buffer corruption for yaz-ztest record fetch.
429 Allow yaz-ztest to return user-defined records (one record per file).
430 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
432 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
433 Use the stream write instead of odr_printf which has a 4K tmp buffer.
435 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
439 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
440 can read and write this format. For record format JSON, yaz-ztest returns
441 MARC-in-JSON records.
443 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
444 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
448 Improve error reporting for ICU chains YAZ-707
449 Report config element+rule when ICU status is "failure".
451 ZOOM: stop fetching if present response has no records YAZ-710
452 Some targets return less records than their hit count would suggest.
453 This prevents ZOOM from continuing to fetch records if any present
454 response has 0 records in the response.
456 Ensure that GFS calls exit if any listener fails YAZ-710
457 Before, if XML config was in use, it would start the default
462 yaz-ztest: -V shows version (like yaz-client -V)
464 New iconv encoding: danmarc YAZ-692
466 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
468 daemon: only wait for immediate child rather than all children. YAZ-704
470 yaz-client: fix setting of SRU record schema. If scheme was unset, it
471 could lead to invalid memory reference.
475 yaz-ztest returns schema for MARCXML test records. SRU require that
476 recordSchema for records.
478 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
479 instead of non-surrogate diagnostic. This is a per-record failure.
481 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
482 may refer to multiple listeners now. Attribute listenref is a comma separated
485 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
486 option is given for GFS, the dirname of filename (for -f) is used
487 as prefix for options such as cql2rpn, ccl2rpn, etc.
489 Content-Type charset fixes YAZ-701 . Do not inspect charset in
490 Content-Type header for SOAP when decoding SRU. The payload (XML)
491 itself tells what encoding it is. In response, never supply encoding
492 in Content-Type. The response payload (XML) tells what it is (with no
493 encoding in XML it's UTF-8).
495 HTTP decoding: allow blanks in URL paths YAZ-700
499 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
500 and facets. Ensure recordData and recordSchema are always present in
501 record element, because they are required.
503 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
506 Simplify in a lot of places using odr_strdupn.
508 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
512 Increase various buffers in GFS's statserv_options_block
513 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
514 This change makes many type-casts redundant, and, thus simplifies code.
516 Remove last bits of WAIS support.
518 Remove member 'size' from Odr_oct.
520 Slim down the public part of 'struct odr'. Most elements are not part
521 of struct Odr_private.
523 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
524 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
525 In particular facets are supported in both client - and server side.
526 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
527 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
528 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
529 both request/response). This is what a search handler in the GFS
530 will see (regardless of whether operating in SRU mode or Z39.50).
532 Changes to the srw.h (SRU/Solr) definitions include:
533 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
534 (char*), which replace union query and query_type (int). This is because
535 SRU 2.0 supports a queryType parameter. This also means that, to carry
536 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
537 x-pquery=PQFstring (extention parameter). The extension parameter
539 - New element, packing, that has information about SRU
540 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
542 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
544 New element, packing, in Z_SRW_explainRequest.
546 New elements in Z_SRW_scanRequest, queryType and scanClause.
547 These replace query_type and scanClase untion. This is similar to what
550 --- 4.2.69 2013/10/01
552 GFS: log when closing down - at least SIGTERM YAZ-684
553 Also change formatting WRT PID logging a bit.
555 Improve display of MARC records with multi-byte subfield IDs YAZ-695
556 In some rare cases subfield identifiers are multi-byte characters.
557 This will try to deterime length of those and split accordingly.
558 This affects display in line mode as MARCXML/MarcXchange. The encoding
559 of ISO2709 is the same.
561 Change inp argument to const for yaz_read_UTF8_char.
563 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
565 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
567 Better check of marc leader info YAZ-691
568 Problem is that some systems generate MARCXML/MarcXchange with
569 funny headers. These will not work if encoded as ISO2709.
570 Some tests produce new output, due to updated warning messages
572 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
574 yaz-client: display MAB records YAZ-689.
575 Thanks for Heiko Jansen for this patch.
577 New utility z_get_HTTP_Response_server which allows both HTTP server name
578 and HTTP server URL to be given in response.
580 Debian: do not depend on obs tcl8.3.
582 Debian: do not depend on obs libicu36-dev.
584 --- 4.2.68 2013/09/23
586 GFS: pass additionalSearchInfo to search memeber search_input if
587 given. Otherwise pass otherInfo. Request for facets and other search
588 related things will be passed there in future versions of YAZ.
590 New ZOOM setting, authenticationMode, which allows authentication
591 paramters to be encoded in the URL rather than via HTTP Basic auth.
594 rpn2solr: fix nested AND/OR handling. YAZ-685
596 Add comparison routines for some Z-types, such as NamePlusRecord,
597 RPNQuery, Query, RecordComposition and OtherInformation.
599 --- 4.2.67 2013/09/19
601 Don't decode MAB as MARC. Just like we don't attempt to decode
602 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
604 CCL: allow quoted terms for date ranges. YAZ-681
606 Introduce ccl_parser_qual_search. This function makes old function
607 ccl_qual_search, from YAZ 2, available again.
609 Add yaz_facet_list_to_wrbuf. YAZ-683
611 --- 4.2.66 2013/09/11
613 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
614 schema was given for search. YAZ-675
616 Add Solr date range searches. YAZ-621
618 --- 4.2.65 2013/08/22
620 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
622 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
624 ISO2709/MARC parse most octet aligned records; not just those that
625 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
626 MARC parse more records instead of just dumping as is. YAZ-670
628 ZOOM: proper caching for variations of record schema. YAZ-671
630 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
632 --- 4.2.63 2013/07/17
636 --- 4.2.62 2013/07/11
638 New utility z_get_HTTP_Response_details - an extended version of
641 New utility yaz_url_get_error which returns error message of last
642 failed yaz_url_exec call.
644 yaz-url and url functions: allow max HTTP redirects to be controlled.
646 New functions yaz_file_glob2, yaz_xml_include_glob.
647 These functions takes a flags parameter, which, for now only controls
648 whether to fail inclusion of a non-existing file (without glob
649 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
651 --- 4.2.61 2013/06/20
653 For MARC XML parsing, allow record without leader. A fake/default leader
654 is inserted and a warning is tagged with the record.
656 ICU: fix leak in in icu_iter_get_org_info.
658 --- 4.2.60 2013/06/14
660 ICU: fix bug in icu_iter_get_org_info (un-init variable).
662 --- 4.2.59 2013/06/11
664 Implement z_HTTP_header_remove.
666 --- 4.2.58 2013/06/11
668 ICU: Disallow 0 ptrs for some ICU string utilities.
670 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
671 returns original tokens (before normalization).
673 CCL: avoid z39.58/regex truncation when not needed. Apply only the
674 conversion of those masks, when absolutely necessary.
676 CCL: configurable masking character - @mask. Default masking character
679 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
680 full response anyway, so a Transfer-Encoding header will obstruct the
683 --- 4.2.57 2013/05/15
685 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
686 picking a socket. Problem is that some systems has IPV6 support, but
687 we can't create sockets for them, so we pick AF_UNSPEC first.
689 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
690 use content_len to determine resulting Content-Length in HTTP response
691 and NOT Content-Length supplied in headers by user.
693 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
694 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
696 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
699 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
700 with big endian and unsigned char (by default).
702 --- 4.2.56 2013/04/26
704 Fix yaz-client connect (crash in 4.2.55).
706 --- 4.2.55 2013/04/26
708 Fix proxy/host problem for ZOOM that could occur if unix sockets
711 New Debian package libyaz4-dbg.
713 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
714 differently in tcpip_close.
716 --- 4.2.54 2013/04/17
718 Windows installer of YAZ includes YAZ4J as a component.
720 CQL: allow "extra terms" again, by default. Thus, the CQL parser
721 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
722 and earlier. CQL parser may operate in strict mode where queries
723 not conforming to the standard BNF are rejected (syntax error).
724 Whether the CQL parser operates in strict mode is controlled with
725 cql_parser_strict . Strict mode enabled with option -S for utilities
726 cql2pqf and cql2xcql .
728 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
730 --- 4.2.53 2013/04/10
732 New charset, MARC-8c, which is like MARC-8 but allows control characters
733 0x01 through 0x1F, except ESC to be passed through verbatim.
735 Fix a problem with duplicate sub field character in MARC output. Problem
736 happened only when output was MARC-8 encoded.
738 --- 4.2.52 2013/04/03
740 yaz-ztest: Use hash for fake hit count. Before, random number was used.
741 This is problematic for unit tests using yaz-ztest. This patch also makes
742 a hash for CQL queries. For RPN, any term with a leading digit will be
743 treated as pseudu hit count (to force any particular hit count by a client).
745 yaz-ztest: return unique MARC dummy records. Beyond record offset
746 24, the author surname is patched with offset to make all records
749 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
750 on system wide default (/proc/sys/net/ipv6/bindv6only).
751 @4 binds to IPV4 only. @6 binds to IPV6 only.
753 Update CQL API documentation a bit
755 CQL: don't accept extra terms for queries. Makes the CQL parser
756 stricly conformant to the standard.
758 --- 4.2.51 2013/02/12
760 GFS: scan handler gets extra_args from request and may return extra
761 response data . That's for SRU only.
763 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
765 --- 4.2.50 2013/01/30
767 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
769 OPACXML: sync spelling of availabilityDate in XML to that of Schema
770 opaxxml.xsd. The schema had the correct spelling of this member always.
771 The ASN.1 was mis-spelled and still is (API change) - we are
772 not changing this. However, the OPAC to XML conversion had yet
775 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
778 New function, z_ext_record_oid_nmem, which is similar to
779 z_ext_record_oid but takes NMEM rather than ODR
781 --- 4.2.49 2013/01/18
783 ICU: New conversion element 'join' which joins tokens into one
784 with a custom character given by rule attribute.
786 --- 4.2.48 2013/01/10
788 New GFS search member: present_number. This is a hint to the
789 search handler how many records are going to be fetched immediately
790 following search. There's no guarantee that it's going to be the case,
791 since it depends on hit count (for Z39.50 piggyback) and whether errors
794 Make a few functions static (private). The functions getbyte_stream,
795 ungetbyte_stream and yaz_gets are now private. They were never declared
798 yaz-marcdump: exit(5) for serious decoding errors
800 ISO2709 decoding: be more picky WRT header
802 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
803 was only used as to indicate that next-result-set-position should be
805 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
806 Based on patch from Ashley Sanders.
808 Make some functions static/private in PQF parsing. Those functions were
809 never declared in a public header and so should not be in use by
810 applications based on YAZ.
812 --- 4.2.47 2012/11/23
814 ZOOM: special options to control APDU logging.
815 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
816 logging of APDUs until "saveAPDU" option is set again. If logging is
817 already enabled the effect is that current APDU buffer is cleared.
818 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
819 logging (default behavior on new connection).
820 The APDUs sent/received can be obtained by using
821 Using ZOOM_connection_option_get(c, "APDU") or
822 ZOOM_connection_option_getl(c, "APDU", &l).
824 GFS: relay implementation_version from backend
825 From 3.0.40 and later, implementation_version from backend was
826 not used in init response at all.
828 --- 4.2.46 2012/11/15
830 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
831 mode at all. Probably never did.
833 Make a new version of ztest.pem that, at least, is not expired.
835 --- 4.2.45 2012/11/13
837 Fix description of CCL directive 'case'.
839 More tight checking of form arguments (yaz_uri_to_array). Makes
840 YAZ better at rejecting big and/or bad POSTs.
842 SRU decoding does not report more than up to 10 invalid arguments.
844 rpn2cql: less quotes in generated terms. Semantics unchanged, but
845 it's prettier this way.
847 --- 4.2.44 2012/10/25
849 New utility yaz_decode_init_diag. Defined in proto.h.
851 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
852 given for unix local socket.
853 The COMSTACK string for doing so is:
856 unix:/myfile:tcp:localhost:9999/mybase
857 unix:/myfile:localhost:9999/mybase
858 unix:/myfile:http://fakehost/mybase
860 debian: Use dpkg-buildflags in build process.
862 --- 4.2.43 2012/10/19
864 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
865 global's SRU service uses a recordPosition scheme starting from zero.
866 First record's position should be one
867 according to the standard.
869 --- 4.2.42 2012/10/18
871 Allow more namespaces for SRU. This is to allow, for example, an
872 incorrect namespace returned from server
873 http://services.igi-global.com/sru .
875 Minor fixes for compilation on Windows.
877 --- 4.2.41 2012/10/11
879 daemon: log total number of bad signals from child on stop so that it
880 is more easy to spot problems with child worker processes.
882 retrieval: empty backend name attribute omits element set
883 from being used in retrieval.
885 --- 4.2.40 2012/10/04
887 Implement Solr sort strategy "solr", similar to sru11 sorting.
888 This will implement the correct parameters on Solr requst to do
891 --- 4.2.39 2012/09/28
893 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
896 MARC: Extra/missing indicator handled for MARCXML.
897 The indicator length is given in header and is the same for the
898 whole record. If attributes ind1, ind2 are missing, then content
899 character defaults to blank. Extra indicator attributes (beyond)
900 indicator length are treated as an error.
902 Reformat: delete trailing whitespace
904 --- 4.2.38 2012/09/17
906 MARC: fix non-ASCII characters for leader. This is to ensure we can
907 generate XML in UTF-8.
909 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
910 in one node with structure word.
912 --- 4.2.37 2012/09/04
914 yaz-json-parse: JSON output may be pretty printed by using option
917 Increase default value of max message for Z39.50 Init for GFS, ZOOM
918 and yaz-client. Old value was 1 MB. New value is 64 MB.
920 --- 4.2.36 2012/08/22
922 yaz-client: don't display bogus records from SRU servers. Some SRU servers
923 return more records than given by *maximumRecords*. Skipping those in
926 record_render: simplify buffer return handling and fix at least one bad
927 memory reference, that broke the test_embed_record sometimes.
929 Allow http://user:pass@host notation for yaz_url_exec.
931 zoomsh: allow shell command to be executed. Via the system(3) call.
933 yaz_poll: Allow num_fds == 0
935 yaz-client: fix bad encoding of "itemorder item". The itemorder
936 item <no> - command forgot to use length of encoded Item Request
937 package. Error present since YAZ 3.
939 yaz-ztest: fix bad usage of session handle. Bug was introduced when
940 result sets were saved (271a9c83).
942 SRU recordPacking: guess record packing in response rather than looking
943 at the recordPacking element which, OF COURSE, changed semantics in SRU
946 Decode SRU 2.0 responses. The official namespace for responses, according
947 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
948 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
949 nature.com's server, however, usee namespace
950 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
951 we are now using a glob-expr to match up the namespace. ZOOM C and
952 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
953 I can not find a single real example showing the "real" namespace in
954 the documentation from OASIS. The namespace for requests is different
955 from responses, but this is not added to YAZ yet, when we don't encode
958 --- 4.2.35 2012/06/26
960 zoom/record_render: add support for Base64 decoding fo MARC records
961 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
962 which will decode base64 + ISO2709 marc-8 encoded material from text node
965 --- 4.2.34 2012/06/07
967 Add missing definitions ZOOM_resultset_get_facet_field_by_index
968 and ZOOM_resultset_facets_names.
970 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
973 Change APDU dump printing to avoid long leading blanks. For levels 16
974 or larger the level is shown and the indentation is truncated but
975 recursed with modula 8. This makes it still reasonable easy to read
976 - even for nested BER dumps.
978 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
979 return 0 (incomplete package) in case where the BER package was
980 considered too nested (return value of -2).
982 dumpber: lines of level 15 are not indented further. Two spaces per
983 indentation; indentation 15 or more is indented to a fixed indentation
984 and augmented with a level=<no> indication.
986 zoomsh: increase max size of command+args
988 GFS: No limit in RPN buf size in CQL to RPN conversion.
990 --- 4.2.33 2012/05/09
992 New function for daemon utility, yaz_daemon_stop .
994 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
996 --- 4.2.32 2012/04/25
998 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
999 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
1001 --- 4.2.31 2012/04/23
1003 YAZ daemon utility relays SIGUSR1 to child process.
1005 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
1006 would result in en empty database list - which in turn would result in
1007 encoding failure for search.
1009 Fix reading beyond string in yaz_sort_spec.
1011 --- 4.2.30 2012/04/11
1013 Add two new SRU diagnostics:
1014 236: Access to specified database denied
1015 1015: Init/AC: Maximum number of simultaneous sessions for Userid
1017 Document the very useful ZOOM-C option "apdulog".
1019 CQL to RPN: term may be passed through verbatim. This is enabled with
1020 truncation.cql . The assumption being that the term is already CQL.
1022 --- 4.2.29 2012/03/20
1024 record_conv: leader spec may be given for marc element.
1025 The leader spec is given as attribute leaderspec for element marc.
1026 For example to convert a MARC21 record from MARC-8 to UTF-8:
1027 <marc inputformat="marc" outputformat="marc"
1028 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
1030 record_conv: allow user-XSLT params. For example:
1031 <xslt stylesheet="MARC21slim2DC.xsl">
1032 <param name="myparameter" value="myvalue"/>
1033 <param name="otherparameter" value="othervalue"/>
1036 record_conv: fix error handling for missing marc charsets.
1038 CQL: fix extra terms in wrong order.
1040 --- 4.2.28 2012/03/06
1042 record_conv: modify new API for conversion types. The conversion types
1043 may be passed in new functions yaz_record_conv_configure_t and
1044 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
1046 Avoid mixed statement/variable declare; fixes compilation with Visual
1049 --- 4.2.27 2012/02/28
1051 Add non-standard SRU diagnostic: 235: "Database does not exist".
1052 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
1053 Update SRU to Bib-1 diagnostic maps accordingly.
1055 CCL: add two new diagnostics for unsupported masking. The new
1056 diagnostics are: "Embedded truncation not supported" and
1057 "Single charcacter mask not supported".
1059 --- 4.2.26 2012/02/23
1061 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
1063 --- 4.2.25 2012/01/11
1065 Build YAZ for Ubuntu Oneiric.
1067 CCL: allow parantheses for proximity operands. For example CCL query
1068 (a) % (b) is now allowed.
1070 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
1071 marked dead, rather then being destroyed. If not, the session memory is
1072 being free'd before the search/scan handler is finished. Also destroy
1073 'request' memory in request_release rather than in various places,
1074 which resulted in leaks from time to time.
1076 --- 4.2.24 2011/12/21
1078 cql_sortby_to_sortkeys: honor sort prefix.
1080 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
1081 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
1082 The rpn2cql family of functions now always returns quoted CQL terms.
1084 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
1086 --- 4.2.23 2011/12/15
1088 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
1089 sequence is treated as one. For example, &&a=b&&&c& is identical to
1092 --- 4.2.22 2011/12/05
1094 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
1095 APDUs for a connection to a WRBUF.
1097 --- 4.2.21 2011/11/23
1099 Fix cql_sortby_to_sortkeys. Completely broken before.
1101 Make CCL's @truncation work again.
1103 --- 4.2.20 2011/11/09
1105 New ZOOM connection setting: tproxy. It's like proxy, but does not
1106 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
1107 to set resolved address + port for a connection outside ZOOM itself.
1109 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
1111 --- 4.2.19 2011/11/07
1113 Fix uninitialized variable in Solr spell support (could cause SEGV
1114 for SRU response decoding).
1116 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
1117 back-end's addinfo through into the ZOOM response addinfo.
1119 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
1120 they are separated by a colon and a space rather than simply
1123 --- 4.2.18 2011/10/28
1125 Add support for Solr spell-checking/suggestions through ZOOM.
1126 If a Solr target has been configured correctly for spelling-checking
1127 and suggestions, these will now be returned on the ResultSet option
1128 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1130 --- 4.2.17 2011/09/28
1132 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1133 with a flag whether to substitute escape sequences or not.
1135 --- 4.2.16 2011/09/22
1137 Fix nmem_strsplit_escape to substitute escape char properly.
1139 New option for zoomsh -e , which makes it abort on first error and
1140 return process exit code to indicate success/failure.
1142 YAZ options utility supports special option -- which makes all it treat
1143 all following arguments as non-options.
1145 --- 4.2.15 2011/09/16
1147 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1148 searched if absolute filename is given.
1150 Fix conv_xslt() error-reporting when stylesheet is not found.
1151 (The value of fullpath is meaningless in this situation.)
1153 --- 4.2.14 2011/09/07
1155 Fix problem in CQL sort node creation: un-initialized memory.
1157 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1158 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1159 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1162 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1163 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1165 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1166 will make it possible to use both single-character mask (#) and wildcard (?)
1167 in CCL . Throw diagnostic for left truncation because that is not supported
1170 --- 4.2.13 2011/09/01
1172 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1173 cases using escapes (\-sequences) and masking.
1175 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1176 would result in a read one byte beyond string.
1178 rpn2ccl may use Z39.50 masking for terms (t=z).
1180 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1182 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1183 not --cppflags (which seeems like an error in icu-config).
1185 --- 4.2.12 2011/08/27 RPM package only
1187 cql2ccl: fix conversion of terms: operator characters were not
1190 --- 4.2.11 2011/08/25 RPM package only
1192 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1193 CCL parser will map both # and ? to their regular expression
1194 quivalents (. and .*).
1196 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1197 of reserved CQL characters.
1199 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1200 is, so that they are passed through.
1202 --- 4.2.10 2011/08/24
1204 ZOOM SRU mode: more aggressive re-connect.
1206 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1207 made available as a utility function, declared in <yaz/logrpn.h>
1209 rpn2cql_structure() supports proximity nodes (except that the Type-1
1210 proximity node's "exclusion" binary is ignored, as there is no way to
1211 express that in CQL). Fixes bug #4564.
1213 --- 4.2.9 2011/08/18
1215 Fix SEGV that could occur if set command of zoomsh was given without
1216 value (2nd argument).
1218 Fix SEGV that could occur if unsupported transport was given for
1219 COMSTACK - say https (when SSL was unavailable).
1221 Build yaz-url on Windows too.
1223 --- 4.2.8 2011/08/11
1225 New utility to get web content. Header is url.h. A command line tool
1226 yaz-url is part of the distribution and packages.
1228 Fixes for SSL COMSTACK (when gnutls is in use).
1230 New functions yaz_base64{encode,decode}. Header is base64.h.
1232 --- 4.2.7 2011/08/03
1234 ZOOM C includes HTTP response buffer as additional info if it fails
1235 to decode the SRU response.
1237 Make wrbuf_json_puts available.
1239 --- 4.2.6 2011/07/28
1241 zoom: throw diagnostic for invalid value for option "sru". Before a
1242 bad SRU request was sent.
1244 Adding new utility wrbuf_vp_puts.
1246 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1248 --- 4.2.5 2011/07/21
1250 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1251 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1252 redirect was used at the same time.
1254 MARC line mode decoding: be less picky about length given - first
1255 5 digits of header that is.
1257 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1259 Changes to decoding of SRU records: a record with recordPacking=xml is
1260 modified with a new root element <yaz_record> if the recordData contains
1261 multiple children elements. This is to make the record XML parseable
1264 RPN to Solr conversion: encode special characters.
1266 Generic Frontend Server: fix uinitialized member, stepSize.
1268 --- 4.2.4 2011/06/21
1270 Fix a bug in SRU decoding of records.. The database records stored
1271 had un-initialized memory, but it would only be seen with yaz_record_render
1272 and type_spec="ext" .
1274 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1276 --- 4.2.3 2011/06/17
1278 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1280 --- 4.2.2 2011/06/10
1282 Add new utilities to convert from CQL to CCL . These utilities have
1283 prefix cql_to_ccl defined in cql.h.
1285 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1286 lead to memory heap corruptions when ICU utilities were in use.
1288 --- 4.2.1 2011/06/07
1290 Make compilation work without Libxml2.
1292 yaz-client: remove redundant blanks in display of searchResult-1 term
1295 --- 4.2.0 2011/05/18
1297 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1298 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1300 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1301 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1302 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1303 Note that the CQL sortby spec is only converted when the GFS is already
1304 converting from CQL to RPN (cql2rpn element).
1306 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1307 specify whether to collapse delimitors or not. The existing nmem_strsplit
1308 do collapse (collapse parameter = 1).
1310 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1312 Rename internal func yaz_use_attribute_create. While non-static, this
1313 function is not declared in a public header.
1315 --- 4.1.7 2011/03/15
1317 Add -lCrun when linking with ICU on Solaris.
1319 More quicks character set conversions for OPAC records.
1321 --- 4.1.6 2011/03/10
1323 fix problem with record_render: records were converted (character set
1324 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1326 --- 4.1.5 2011/03/08
1328 SRU: add methods for handling DADS SRU-proxy facets.
1330 Separate OPAC record character set for ZOOM_record. yaz_record_render
1331 allows a character set given as charset=from/opacfrom,to where 'from' is
1332 the character set of a bibliographic record, 'opacfrom' is character set
1333 of OPAC record and 'to' is the target character set.
1335 --- 4.1.4 2011/02/21
1337 yaz-client: show may XML format records. Command show followed by 'format'
1338 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1341 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1344 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1346 --- 4.1.3 2011/01/27
1347 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1349 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1350 this package can be distinguished from other vendors.
1352 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1353 as determined by configure
1355 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1357 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1358 returns no error and no record, the present request is considered
1359 partial (only a subset of the records could be returned by backend), and
1360 so it is appropriate to set Present Status to partial-4.
1362 --- 4.1.2 2010/11/02
1364 Move yaz-config man pages to section 1.
1366 More documentation about Solr.
1368 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1369 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1370 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1371 peers on some Linux systems. However, in general that does not work
1372 so YAZ can not rely on that to work. Debian changed behavior in this
1373 respect from Debian lenny to Debian squeeze (still testing as of Oct
1375 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1377 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1379 --- 4.1.1 2010/10/05
1381 Fix yaz-config output: echo_source not set correctly by configure.
1383 --- 4.1.0 2010/10/05
1385 Solr Web Service support for yaz-client and ZOOM.
1387 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1389 --- 4.0.12 2010/08/17
1391 Z39.50 facet support. Facet specifications are passed for search in
1392 other-information with ASN.1 as defined in facet.asn and OID
1393 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1394 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1395 3 is limit (number of entries to get in response). yaz-ztest returns
1396 dummy facets if a client asks for them.
1398 --- 4.0.11 2010/07/09
1400 CCL fixes: bug 2895 and bug 3539.
1402 GR1-display: add comma in display - was removed by mistake in
1405 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1407 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1409 --- 4.0.10 2010/06/18
1411 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1412 result set from a connection. The result set will be on its own
1413 thereafter; no operations on it will perform retrievals from a target.
1414 Only cached copies are returned.
1416 ZOOM C:fix case for HTTP servers responding with Connection:close.
1417 Ensure that if there is a current task it is resumed (like fetching
1418 more records in a result set) . Bug #3484.
1420 PQF parser: use odr_atoi for Odr_int (not atoi)
1422 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1423 values that contain any non-digits are treated as string attributes
1424 (previously decoding only checked for leading character ([0-9]). PQF
1425 encoding: attribute string values are not surrounded by double-quotes.
1427 --- 4.0.9 2010/05/21
1429 New utility for managing threads - thread_create.h.
1431 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1432 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1433 but YAZ' implementation do.
1435 Fixes for yaz_cond-functions on Windows 7.
1437 DLL export more symbols.
1439 zoomsh: show record do NOT render opac.
1441 Remove *.la files from Debian and RPM packages.
1443 --- 4.0.8 2010/05/11
1445 Debian package libyaz-dev depends on libgnutls-dev again (was
1446 removed in YAZ 4.0.6, but due to Libtool it is still needed
1447 even though yaz-config do not list libgnutls libs).
1449 ZOOM: Use only one WRBUF for returning string results for
1450 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1452 ZOOM: ZOOM_connection do not use a shared pointer to
1453 ZOOM_resultset after ZOOM_resultset is destructed by
1454 user. Reverts to YAZ 4.0.4 behavior.
1456 --- 4.0.7 2010/05/04
1458 record-conv: fix problem with at least one XSL conversion -
1459 due to probably incorrect usage of XML XSL documents.
1461 --- 4.0.6 2010/04/29
1463 Fix yaz-config for static mode and the use of SSL (gnutls).
1465 --- 4.0.5 2010/04/29
1467 Forward decl timeval struct in mutex.h and gettimeofday.h.
1469 yaz-config: fix 'static' mode linking.
1471 --- 4.0.4 2010/04/28
1473 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1474 are wrappers for pthreads or Windows. For Windows these are put in
1475 a separate DLL: yaz_cond4.
1477 libyaz.la (whole source) is compiled with thread. If thread support
1478 is enabled enabled, all source of YAZ is compiled with treading support.
1479 This allows core utilities such as yaz_log to use thread facilities.
1480 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1481 thread utilities. This commit moves mutex utilities (mutex.c) from
1482 libyaz_server.la to libyaz.la.
1484 yaz-json-parse displays leading text until error.
1486 --- 4.0.3 2010/04/09
1488 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1489 patch from Giannis Kosmas.
1491 SRU: no longer URL encode SRU database. The URL for an SRU server is
1492 a URL and such is alreeady encoded - at least when given with leading
1493 http:// or https://. This reverts behavior to YAZ 3.0.50.
1495 Support for new MARC XML notation TurboMARC which like MARCXML is a
1496 complete representation of MARC/ISO2709.. This one, however, is more
1497 compact and allows for faster processing with XSLT. TurboMARC can be
1498 used in the marcdisp.h API, from the yaz-marcdump utility and from
1501 yaz-ztest can be configured - via the database - to perform certain
1502 delays when it performs operations search, present and single record
1503 fetch. This allows testers to make yaz-ztest act as a real or even slow
1504 Z39.50 server. Refer to the yaz-ztest man pages for details.
1506 --- 4.0.2 2010/03/09
1508 wrbuf_destroy allows NULL WRBUF passed to it.
1510 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1512 Add ZOOM_connection_close.
1514 No fixed size buffers for ZOOM shell - bug #3257.
1516 tstodr: make it work on s390 platform.
1518 New icu iterator-functions. The new icu_iter-functions makes it possible
1519 to use ICU chains from many threads.
1521 yaz-client: better syntax check for show command.
1523 --- 4.0.1 2010/01/26
1525 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1528 New simple local-file XML include facility which allows file glob-patterns.
1529 Refer to yaz/xml_include.h.
1531 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1534 ZOOM_record_get supports new parameter "format" which makes it format XML
1537 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1538 JSONText in ECMA-262) is JSONValue, not JSONObject.
1540 --- 4.0.0 2010/01/20
1542 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1543 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1545 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1546 POSIX/Unix builds .so with major version 4.
1548 Remove old LOG_-defines from log.h. They have been obsolete and
1549 undefined by default for the last 5 years.
1551 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1553 GFS: Remove socket (int *fd) from search_rr handler. The socket
1554 descriptor ptr is a facility that allowed a search handler to supply
1555 a socket which would serve as a callback - when search was complete.
1556 This facility has now been in use for years.
1558 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1559 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1560 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1561 returns 'const char *' rather than 'char *. The returned string is
1562 read-only and should not be modified by applications. COMSTACK cs_close is
1563 now a void function - it no longer returns int. No applications check for
1564 the value and the implementations has always returned 0.
1566 ZOOM: use size_t for scan hit counts and str size. Functions
1567 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1568 occ (hit count) and len (string length) are now of type size_t pointer
1569 rather than int pointer. This is to be able to represent large hit counts
1570 and to also just to use the proper type for string length (strlen result).
1572 New JSON parser. Refer to include/yaz/json.h .
1574 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1575 Used to be int in some cases. Many wrbuf_-functions used to return an int
1576 indicating some length.. These return values were never used. And so they
1579 ODR: odr_malloc, odr_total now takes size_t for size.
1581 clone_z_type: fix leak; occurred for encoding failures.
1583 --- 3.0.52 2009/12/03
1585 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1586 bug was introduced in 3.0.51.
1588 --- 3.0.51 2009/12/02
1590 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1592 tcpip comstack: fix leak for getaddrinfo.
1594 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1595 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1596 Decoding of SRU "path" database is performed by private function
1597 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1598 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1600 yaz-client: honor base command for SRU. Change when database setting
1601 is applied for SRU and ensure it is kept when a connection is reset.
1602 Change also the way errors are displayed or SRU (decoding of packages).
1604 --- 3.0.50 2009/11/02
1606 Add support for extra request / response data for SRU codecs and GFS.
1607 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1608 for extra data response buffer and length. For the GFS, both request
1609 and response data (XML) is carried in extra_args and extra_response_data
1610 for the search handler. Patch by Ko van der Sloot.
1612 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1613 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1614 10010). This fixes bug #2113.
1616 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1617 cmdfile included a 'quit' command that would result in a memory violation.
1619 --- 3.0.49 2009/10/01
1621 Make a number of functions defined in xmlquery.c static. These have
1622 never been declared in a public header file (yaz/xmlquery.h) and was
1623 made public by mistake.
1625 Improve speed of character conversions (iconv utilities). This makes
1626 conversions from MARC-8 faster.
1628 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1629 unless type desired is "raw". This will prevent type "xml" from
1630 returning ISO2709 .. Which obviously can not be XML parsed.
1632 Fix memory leak in ZOOM that would occur if option apdulog was used
1633 on a re-used connection.
1635 Frontend server logs HTTP requests.
1637 Frontend server now sends Z39.50 close when it times out (sesssion has
1638 been idle for too long). Versions 2.0.30 and earlier also sent close.
1639 But due to a mistake this was disabled in all versions after that, i.e.
1640 the server would just close the socket immediately.
1642 yaz-client emits a better message when receiving an unrecognised
1643 userInformationField.
1645 Skip zero-length subfields when decoding ISO2709. This rare case happens
1646 if a record has two FS characters in a sequence. Without this patch
1647 there would be a reference beyond char array in using_code_len fragments
1650 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1652 --- 3.0.48 2009/08/28
1654 The show command offered by the zoomsh command now takes a 3d optional
1655 parameter type which is what is passed to ZOOM_record. If the type
1656 argument is omitted, "render" is used.
1658 RPN to CQL conv may use USE string attributes (bug #2978).
1660 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1662 --- 3.0.47 2009/07/08
1664 Function yaz_xml2query allows a diagnostic element in the PQF XML
1665 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1666 code and additional info respectively.
1668 The BER BOOLEAN is now the integral type Odr_bool which still happens
1669 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1670 typedef'd to Odr_int. This is still an integral 'int', but it may be
1671 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1672 ASN-1 compiler as well as programs has been updated to use the new types.
1674 --- 3.0.46 2009/06/08
1676 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1677 only the bibliographic record was rendered. For type=opac, an OPAC
1678 record is only returned if it is present.
1680 iconv: small fix for encoding of advancegreek.
1682 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1684 yaz-client: option auto_reconnect=on really reconnects.
1686 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1688 server: avoid null ptr ref for for yaz_poll errors.
1690 build: fix RPM build for RHEL 5.3.
1692 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1694 --- 3.0.45 2009/03/31
1696 Fixed bug #2709: TCP connect returns Invalid argument.
1698 Fixed compilation for mingw.
1700 Honor charset for raw records (ZOOM_record_get).
1702 Fixed use of errno for threaded mode that was seen on Solaris 10.
1704 Fixed argument passing with blanks in value for Windows Service.
1706 Disable YAZ' own log rotate by default (no 1 GB limit).
1707 The variable l_max_size which specifies the log file limit is set to 0
1708 (DISABLED): This is due to the fact that YAZ is most often deployed using
1709 logrotate. Also YAZ can not perform log rotate because of unsufficient
1710 permissions (setuid).
1712 --- 3.0.44 2009/02/17
1714 List supported encodings in man page for yaz-iconv.
1716 Fixed missing SSL libs for --libs output
1718 Re-established OID record syntax application-xml. Nobody should use it
1719 but we don't want to change soname because of this symbol being absent.
1721 --- 3.0.42 2009/02/02
1723 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1725 Added member named_result_sets for init handler struct for the GFS. This
1726 allows a server to disable named result sets.
1728 Removed OID record syntax application-xml.
1730 Added support for rule-based transliterator for ICU wrapper of YAZ.
1732 Fixed bug #1902: yaz-icu XML output.
1734 Make YAZ checks Emacs friendly.
1736 BITSTRING value shows value. Bug #2346.
1738 ISO2709 decoding: skip control characters from indicator data.
1740 Omit sort key by default in yaz-icu's output.
1742 Allow combined single char options (again) for YAZ' options function.
1744 Utility yaz-marcdump got option to display YAZ version (-V).
1746 Allow YAZ to use ICU 3.4.
1748 Added new ICU test case which illustrates removal of diacritics.
1750 --- 3.0.41 2008/12/29
1752 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1754 --- 3.0.40 2008/12/29
1756 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1759 Fixed bug #2352: yaz-marcdump crashes for certain record.
1761 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1763 Added support for Danmarc2 to UTF-8 conversion.
1765 Added support for ISO5426 to UTF-8 conversion.
1767 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1768 implementation version.
1770 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1772 --- 3.0.38 2008/11/10
1774 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1775 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1777 ZOOM C now interprets databaseName option for ZOOM connection as path
1780 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1782 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1784 Dummy Libxml2 types no longer defined in headers of YAZ'.
1786 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1789 --- 3.0.36 2008/09/26
1791 Various ODR chapter fixes.
1793 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1795 Added missing source for Windows compilation, mutex.c.
1797 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1799 For SRU connections in ZOOM all records up to "count" are now fetched.
1801 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1802 in Windows due to bad error handling for Libxml2.
1804 Added facility for sending arbitrary records (ASN.1 any) using
1805 ZOOM C's Extended service update. Patch by Sam Reynolds.
1807 New options for ZOOM C's connection, logapdu which makes ZOOM log
1810 --- 3.0.34 2008/06/18
1812 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1814 --- 3.0.32 2008/06/12
1816 Fixed memory violation that could occur when decoding UTF-8. This bug
1817 was only present in 3.0.30 of YAZ.
1819 --- 3.0.30 2008/06/06
1821 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1822 GNU TLS is used by default (if found).
1824 yaz-ztest returns OPAC records if a client asks for OPAC.
1826 Improved speed of MARC-8 encoding.
1828 Added support for lossy and loss-less MARC-8 encoding.
1830 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1832 Added new Windows Service wrapper (sc).
1834 yaz-client's itemorder command may now send a file.
1836 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1838 Added new function yaz_log_xml_errors.
1840 Allow (but warn) unknown XML attributes in MARCXML parsing.
1842 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1844 The UTF-8 to MARC-8 conversion now uses a different set of characters
1845 for Greek symbols. Bug #2120.
1847 --- 3.0.26 2008/02/21
1849 Added yaz_daemon (daemon.h).
1851 Fixed bug #2068: pkg-config trouble
1853 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1855 --- 3.0.24 2008/01/28
1857 Document --with-xml2 option.
1859 Added OPAC XML XSD (etc/opacxml.xsd).
1861 Allow glob mask for name attribute in retrieval element for the
1862 generic frontend server's retrieval facility.
1864 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1865 except POLLIN/POLLOUT.
1867 Fixed error handling in cs_listen. Bug #2037.
1869 --- 3.0.22 2008/01/20
1871 Fixed version in yaz/yaz-version.h.
1873 Fixed bug #2027: Crash when closing connection.
1875 Changed configure so that ICU support is only enabled if only ICU
1876 and Libxml2 is available (because the ICU chain is XML based).
1878 --- 3.0.20 2008/01/15
1880 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1881 is built. Only this DLL depends on the ICU runtime.
1883 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1884 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1886 Changed license of CCL module to 'Revised BSD'. After consultation with
1887 remaining members of the original EUROPAGATE consortium, we are re-issuing
1888 the CCL module without a separate license. The software was developed by
1889 Index Data as part of a research project. The special license was included
1890 to help feed usage information back to the project consortium to support
1891 project evaluation. At this time, the project consortium has long-since
1892 disbanded, and the majority of the original principals have retired. At the
1893 same time, we have significantly modified the software during the following
1894 years, to the point where very practically no original code remains. To
1895 simplify re-use of the software, we have contacted those members of the
1896 consortium who could be reached, and agreed to re-issue the module as a
1897 proper part of the YAZ package.
1899 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1901 CQL closer to being version 1.2 compliant. CQL also allows free-form
1902 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1905 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1906 bug could make Extended services handling crash in the ZOOM layer. This
1907 bug was only present in YAZ 3.0.18.
1909 --- 3.0.18 2007/12/19
1911 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1914 yaz-marcdump reads and writes collection wrapped records.
1916 Handle OPAC for record conversion module.
1918 Fixes for ICU wrapper.
1920 Allow ICU libs to be controlled with --with-icu .
1922 --- 3.0.16 2007/11/12
1924 Added yaz_poll which is a wrapper for select/poll. When poll is available
1925 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1926 sockets to be in use.
1928 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1929 functionality through an XML based configuration (ICU chain). This system
1930 is useful for search facilities such as Pazpar2 and Zebra that needs to
1931 perform tokenization of indexed material. The ICU code in a separate
1932 library libyaz3_icu.a.
1934 Added HTTP tunnel facility for COMSTACK, bug #1752.
1935 This is a facility that allows a Web proxy, such as squid, to tunnel
1936 Z39.50 traffic. This facility is "transparent" to must applications
1937 using YAZ. It's enabled by using pseudo transport connect: followed by
1938 the proxy address, followed by command, then follwed by he regular
1939 "virtual" addresss. For example,
1940 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1942 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1944 --- 3.0.14 2007/09/21
1946 Fixed bad memory reference in ZOOM_record - cuased by member not being
1947 initialized. This was a problem only in YAZ 3.0.12.
1949 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1950 fields were not removed.
1952 Changed the way C code is generated from codetables.xml. Made a MARC-8
1953 conversion trie for each characterSet section rather than codeTable.
1954 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1955 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1957 --- 3.0.12 2007/09/12
1959 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1960 from ZOOM_record_error).
1962 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1964 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1966 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1968 Better SRW-to-Bib-1 diagnostic mapping.
1970 ZOOM C and yaz-client announces SRU version 1.2 by default.
1972 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1975 Fixed in yaz_sru_decode to allow other version than 1.1.
1977 --- 3.0.10 2007/08/22
1979 Added support for SRU scan for ZOOM.
1981 Added support for the use of the older versions or Extended Service
1982 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1983 set to the version , 1=first, 2=second, 3=third. The third version is
1984 what ZOOM C has used so far. And that, obviously, is the default.
1986 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1987 therefore in Zebra and in SimpleServer-based applications). The new
1988 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1989 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1990 which is passed into the back-end search callback function.
1992 Added support for HTTP Basic authentication in clients: the SRU/W
1993 codec encodes the username/password elements of the PDU structure
1994 appropriately, and these may be set using the "user" and "password"
1995 options in ZOOM-C applications (the same options that are used for
1996 Z39.50 authentication).
1998 --- 3.0.8 2007/06/25
2000 Fixed bug #1208: SSL appears to be broken in ZOOM.
2002 Fixed bug #1206: Libxml2 include path weirdness.
2004 Added oid_name_to_dotstring.
2006 Allow elementSetName to be specified for ZOOM C record update.
2008 Allow waitAction to be specified for ZOOM C based for Extended Services.
2010 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
2011 syntax OID. Bug introduced in YAZ 3 series.
2013 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
2015 --- 3.0.6 2007/06/06
2017 Fixed bug #1157: yaz-client does not read .yazclientrc from current
2018 directory. yaz-client now reads commands from file given by option -f
2019 if specified; then tries to read .yazclientrc in current directory.
2020 Failing that, it reads .yazclientrc from user's home directory.
2022 Added support for correlationInfo Note and ID for Record Update via
2025 Added yaz-client command querycharset which specifies character set for
2026 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
2027 (termListAndStartPoint).
2029 Charset ISO5428:1984 is an alias for ISO5428-1984.
2031 Implemented a way to perform scan in a result set using Z39.50. This
2032 is achieved by attaching the result set name in the characterInfo
2033 (type InternationalString) of OtherInformation in the Scan Request PDU.
2034 The result set is identified in the otherinformation by the new OID:
2035 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
2036 This allows for scan in result set and faceted search . Zebra did some
2037 of this in the APT term using attribute type 8 and value being result
2038 set. Using the OtherInformation approach for this is cleaner and easier
2039 to work with in proxies and the like. This facility can be used in
2040 yaz-client using new command setscan which takes a result set as first
2041 argument, start position (APT) as second.
2043 Changed decoding of SRU XML packed records to deal with servers that
2044 have recordData with XML data with multiple root nodes. Also make
2045 comparison for recordPacking case insensitive. Again, one server
2046 returns "XML" where others return "xml".
2048 For SRU responses allow Content-Type application/xml as well as text/xml.
2050 --- 3.0.4 2007/05/21
2052 Fixed bug in character set conversion of BER strings. Bug introduced
2055 --- 3.0.2 2007/05/08
2057 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
2059 For OID class, use oid_class consistently.
2061 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
2064 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
2065 character set for bibliographic information interchange". By Giannis Kosmas.
2067 Added documentation on new OID API.
2069 --- 3.0.0 2007/05/02
2071 Changes to generic frontend server interface: added new member
2072 'query_charset' for bend_initrequest structure. A backend init handler
2073 should set this member to its native character set for query terms.
2074 When defined, the frontend server logic will announce this character set
2075 to a client if the negotiationModel bit is set by the client. All server
2076 implementors are encouraged to specify this. If a backend server does not
2077 specify this a warning is issued using yaz_log(YLOG_WARN,..).
2079 Added CCL utility to remove terms (stop words) from resulting RPN
2080 tree. This is handled by functions with prefix ccl_stop_words_ .
2082 New ZOOM C option, "rpnCharset", which allows client-side conversion of
2083 terms in RPN queries.
2085 Clean-up the CCL API. Moved some internal structures from ccl.h to
2086 private header cclp.h. Changed ccl_parser_create so that a Bibset must
2087 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
2088 This is replaced by ccl_parser_find_str which takes a string instead.
2090 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
2091 libyaz.la is the core of YAZ except the generic frontend server and
2092 does not depend on POSIX threads anymore. libyaz_server.la is the
2093 generic frontend server facilities and uses POSIX thread functionality
2094 if available. The libyaz.la no longer depends on POSIX threads because
2095 the number of global structures is limited. NMEM no longer re-uses blocks
2096 between threads ; it simply free's memory immediately but allocates in
2097 "large" chunks as usual. We don't expect any performance penalties
2098 because of this. The yaz_log system is still using a global log_level so
2099 caution must be taken when modifying it with yaz_log_init_.. +
2100 yaz_log_mask_str. This, however, should not cause any trouble because
2101 these functions are called during initialization of application code
2102 anyway. `yaz-config --libs server` returns libs for server applications;
2103 `yaz-config --libs` returns libs for non-server applications.
2105 New OID database - with public definitions in oid_db.h. Removed old OID
2106 database including the head oid.h and definitions such as enum oid_value
2107 and struct oident. The new OID database uses the same string names as
2108 before but the 'protocol' is gone. There are now only two representations
2109 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
2110 converts from string to OID; functions with prefix yaz_oid_to_string
2111 converts the other way.
2113 Change to emit_term() in CQL-to-PQF query translation: when a term has
2114 the /regexp relation modifier, do not process it for leading and
2115 trailing "^" and "*", which have quite different meanings in regular
2118 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2119 write handlers no longer carries a 'last' parameter. This will make
2120 yaz_iconv flush "less" characters. A flush is performed by call to
2121 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2123 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2124 removed, because function yaz_query_to_wrbuf does the same.
2126 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2127 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2129 Deprecated MARC utility functions removed.
2131 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2134 Branch split: YAZ_2_1_55_branch
2136 --- 2.1.54 2007/03/16
2138 Fix to ZOOM-C so that transparent reconnection is properly handled on
2139 connections that are in asynchronous mode.
2141 Fixed compilation on OpenBSD 4.0.
2143 Large strings in GRS-1 records are now properly displayed in yaz-client.
2145 Added character conversion support for "advancegreek"; based on patch from
2148 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2149 sequence is met. Before the error was not set so it would be unknown.
2151 Adjust yaz-marcdump MARC reader so that it skips until record separator
2154 --- 2.1.52 2007/03/07
2156 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2157 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2158 fd_set structure used as a bitmask for the FDs to be selected on.
2160 Using ACX_PTHREAD macro to check for POSIX threads.
2162 Fixed have-vsnprintf check.
2164 --- 2.1.50 2007/02/23
2166 Fixes for configure on BSD. Bug #900.
2168 Added snprintf/vsnprintf wrappers for systems that don't have
2169 limits (heavens forbid).
2171 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2172 created before all previous tasks were completed and removed from the
2173 task queue, the new task could be removed by a mistake.
2175 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2177 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2179 Fixed bug #832: Problem with MARC/charset in yaz-client.
2181 Fixed bug #668: save command line history for yaz-client.
2183 Fixed bug #830: pkg-config support.
2185 --- 2.1.48 2007/01/23
2187 Extended ZOOM result set options with two options that may be read by
2188 a client: resultSetStatus and presentStatus with values as specified for
2190 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2192 Fixed bug #827: Using SSL fails on Debian etch.
2194 Fixed bug #826: Weird looking chars for set of MARC records.
2196 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2197 that is treated as an ItemOrder with itemRequest being an XML document
2198 external. The value of "doc" is the content.
2200 Extended the GFS search facility. New member of bend_search_rr
2201 'estimated_hit_count' signals that hits is known to be an estmate
2202 (higher or lower than real hit count). New member 'partial_resultset'
2203 signals that the search was partial (hit count is lower or equal than
2204 real hit count). For Z39.50, the information is stored in resultSetStatus
2205 member of SearchResponse APDU. For SRU, the information is signalled
2206 via SRU diagnostic 59: "Result set created with valid partial results
2209 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2211 --- 2.1.46 2007/01/13
2213 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2215 Added ZOOM_connection_peek_event.
2217 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2218 the following new functions:
2219 ZOOM_event_nonblock, ZOOM_connection_process,
2220 ZOOM_connection_get_{socket,mask,timeout},
2221 ZOOM_connection_fire_event_{timeout,socket}.
2222 The existing blocking event handler, ZOOM_event, is a wrapper for the
2223 + blocking ZOOM_event_sys_{poll,select}.
2225 Implemented function ccl_xml_config which parses XML version of CCL
2226 configuration (bug #798).
2228 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2230 Added timings utility (yaz/timing.h)
2232 --- 2.1.44 2007/01/03
2234 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2237 Fixed bug #779: Rotation of apdu.log fails.
2239 Fixed for character set conversions:
2240 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2241 Honor G1 set in MARC-8 decoding.
2243 --- 2.1.42 2006/12/17
2245 Fixed bug #775: char conversion does not handle Alternative UTF-8
2248 Implemented function yaz_marc_read_line which parses MARC line format
2249 records. There is a wealth of formats out there. So far, this function
2250 reads line records produced by yaz_marc_write_line.
2252 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2253 more generic and easier to remember(!) options: -i format and -o format
2254 which specifies input format and output format respectively - where
2255 format is one of "marc", "marcxml", "line", "marcxchange".
2257 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2258 does not print anything except warnings for records.
2260 For yaz-marcdump, added support for MARC split into files (-s) with a given
2263 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2264 spec, at http://www.loc.gov/standards/sru/record-update/
2265 This has changed the binary layout of the following structs:
2266 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2267 bend_update_rr . Patch by Ko van der Sloot.
2269 Added GFS utility function bend_assoc_is_alive which returns 1 if
2270 association is still alive (client is connected); 0 otherwise (client
2271 closed connection). This allows busy servers to stop working for
2274 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2275 been a separate piece of software. This version of ziffy has been modified
2276 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2278 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2280 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2281 Client code may now interrogate options such as "init_opt_sort" to
2282 find out whether the server claims to support various options.
2284 --- 2.1.40 2006/11/27
2286 Added utilities yaz_{set,get}_esn to set/get element set name from
2289 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2290 of YAZ and has been so since YAZ 2.1.10.
2292 Implemented ZOOM_record_error which returns error information for
2293 record (surrogate diagnostic).
2295 --- 2.1.38 2006/10/31
2297 Updates for SRU Update by Ko van der Sloot:
2298 1. Changed name from "operation" to "action"
2299 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2300 versions in the code, marked as 'backward compatible'.
2301 3. Added diagnostics for SRU Update.
2303 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2305 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2307 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2309 For GFS, fixed problem with SRU diagnostic 'First record position out of
2310 range' being issued for 0 hits.
2312 zoomtst10 part of Windows Build.
2314 --- 2.1.36 2006/10/13
2316 Implemented yaz_filepath_comp which splits a path into file path
2317 components (required by Zebra 2.0.3+).
2319 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2320 BSD inspired license until now so this should not have any real impact on
2321 anybody. See http://www.opensource.org/licenses/bsd-license.php
2323 Fixed bug #687: Missing log lines.
2325 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2328 Fixed bug #689: SRU diagnostics to be added.
2330 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2331 whether a connection is idle (no more work do do).
2333 --- 2.1.34 2006/10/04
2335 Change type of optval from long to int for invocation of setsockopt with
2336 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2338 Added support for specifying the max log file size for the Generic
2339 Frontend Server. The size is given with option -r.
2341 --- 2.1.32 2006/09/21
2343 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2345 --- 2.1.30 2006/09/17
2347 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2350 Fixed bug in Generic Frontend Server that could cause a server to stop
2351 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2353 For the generic frontend server, the maximum record size is used as maximum
2354 size of incoming packages (SRU + Z39.50). The value until was previously
2355 only used in Z39.50 Init negotiation and, later, in a session controlled
2356 sizes of records returned. This is controlled using -k option. It can be
2357 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2359 --- 2.1.28 2006/09/04
2361 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2364 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2366 New option for yaz-marcdump -lpos=value which allows setting a portion
2367 of MARC header to a certain value.
2369 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2371 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2372 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2374 --- 2.1.26 2006/08/15
2376 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2379 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2381 --- 2.1.24 2006/08/08
2383 Fixed MARC ISO2709 encoding routines to deal with character set
2386 Minor changes to GFS logging. Database included in search request log
2389 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2390 cached/multiple records.
2392 Shared libraries are built by default on Unix+configure.
2394 Changed cql2pqf transformation to use a different evaluation order. The
2395 new order is: always, relation, structure, position, truncation, index
2396 and relationModifier. Old order was: always, relation, relationModifier,
2397 structure, index, position, truncation. Note that the the latter ones
2398 override former ones for identical attributes.. The new scheme means that
2399 it is possible to override any existing attribute with a relationModifier.
2400 And also that it is possible to override everything for the index rule
2401 (except the ones listed in relationModifier). No order is perfect but this
2402 one, we believe, covers more real cases.. The "always" should have been
2403 called "default", since the attributes there can be overridden with all
2406 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2407 compilation phase, but also for yaz-config --cflags output. This allows
2408 us to have public headers with Libxml2 stuff in them . It should also,
2409 eventually, make Libxml2 checks redundant in packages using YAZ, such
2412 --- 2.1.22 2006/06/15
2414 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2415 stored in uri, message and details.. Previously diagnostics were stored
2416 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2417 compatibility.. but he's probably the only one affected, so.
2419 Added support for CCL, compiled on the client side, in ZOOM-C. This
2420 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2421 input; the resulting query objects can be used for for searching with
2422 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2424 YAZ' configure searches for OpenSSL by default.
2426 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2427 SL_CTX_use_certificate_file. See
2428 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2429 for more info. Thanks to Ko van der Sloot.
2431 --- 2.1.20 2006/06/02
2433 Bug #600: SRU GET, POST support for yaz-client. Introduced
2434 command 'sru' which selects method SOAP/GET/POST.
2436 Allow missingValueAction to be specified for the sortspec string -
2437 function yaz_sort_spec. By default, the missing value action is null.
2438 Use ! to specify "abort". Use = followed by stringvalue to specify default
2441 Ensured that Present-handler (if defined) is called in GFS before any call to
2442 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2443 searchRetrieve requests.
2445 Documentation for YAZ is now based on the Docbook XML/XSLT using
2446 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2447 is no longer depending on jade/openjade or docbook-to-man scripts.
2448 PDF is no longer part of the distribution - but can optionally be
2449 made using DSSSL/jadetex or FOP.
2451 Added retrieval handling support in Generic Frontend Server to support
2452 conversion between MARC/XML as well as XSLTtransforms. See
2453 etc/yazgfs.xml for an example.
2455 Added Authentication support to Generic Frontend Server in SRU
2456 mode. Authentication using HTTP Basic is supported, as is the use
2457 of 'x-username' and 'x-password' parameters in the request itself.
2459 Added support for a new character set MARC8s identical to MARC8 except
2460 that it converts combined characters to single Unicode characters in the
2461 Latin-1 range (when possible).
2463 --- 2.1.18 2006/04/24
2465 ASN.1 compiler 0.4: generates brief Doxygen file header for
2466 generated .h/.c files.
2468 Utility yaz_iconv now supports conversion to MARC-8.
2470 New facilities for the MARC module. The reading - and writing of
2471 content are separate methods for the yaz_marc_t handle. The following
2472 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2473 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2474 format). Write functions have prefix yaz_marc_write_.. The existing
2475 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2476 available. Removed support for OAI-MARC and simplexml (not the
2477 simplexml from PHP5).
2479 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2480 to be returned for this connection.
2482 --- 2.1.16 2006/03/31
2484 Allow multiple languages and charsets to be specified with
2485 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2486 negcharset iso-8859-1,utf-8
2488 Translation of proximity nodes from CQL into PQF now works.
2490 Moved to automake 1.8, 1.9.
2492 Added function yaz_log_set_handler which allows a log handler to be
2493 installed. This handler will be called for all log messages. Output
2494 to file is also produced; but that can be disabled by passing NULL
2495 fname to yaz_log_init_file.
2497 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2499 For SRW (including GFS), accept application/soap+xml as content-type
2502 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2503 produces NO stylesheet reference even if a default stylesheet is specified
2506 --- 2.1.14 2006/03/14
2508 Updated Windows package to include yazd.dll + yazd.lib for the
2509 Development component.
2511 If the environment variable YAZ_LOG is set, then it is used as a
2512 string indicating the default level of logging to use if not
2513 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2514 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2515 used as before. So, for example, to omit warnings from YAZ logging,
2516 export YAZ_LOG=-warn
2518 cql_transform() now map structure and other attributes before indexes,
2519 so that index-specific structures and other attributes can override
2520 defaults. So now a combination of mapping specifications such as:
2522 index.dc.date = 1=date-modified 4=5
2523 does the right thing.
2525 cql_transform() now also respects the "always" mapping specification,
2526 which establishes an initial set of attributes to be used for all
2527 terms except where overridden by more specific attributes associated
2528 with the index, relation or modifier.
2530 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2531 which mode to use; one of "post", "get" or "soap" (SRW, default).
2533 Fixes for yaz_iconv routines: changed trie-based character set conversions
2534 to use only non-negative values for bit fields due to Sun's C compiler not
2535 supporting negative values.
2537 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2538 sequences where not read correctly. Fix by Rustam Usmanov.
2540 Updated win/makefile to use options, settings which makes things
2541 compile with VS C 2005.
2543 --- 2.1.12 2006/02/01
2545 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2547 In ZOOM socket code, use select instead of poll on MacOSX.
2549 ZOOM-C now support client-side compilation of CQL into RPN that is
2550 sent to the server, enabling CQL to be used against all Z39.50
2551 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2552 ZOOM_query object, and submit it using ZOOM_connection_search().
2553 The CQL-to-RPN translation uses a configuration file, the name of
2554 which must be specified in the Connection's "cqlfile" option.
2556 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2557 function, which takes as its start-term parameter a ZOOM_query object
2558 (which may have had either CQL or RPN set into it).
2561 --- 2.1.10 2005/11/29
2563 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2564 GFS to support this as well. Backend handler, bend_srw_update, does the
2565 update work. Code contributed by Ko van der Sloot.
2567 Allow retrieval of Search Result-1 information in ZOOM by the use of
2568 options that are attached to a result set. ZOOM documentation updated
2571 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2572 UTF-8 conversion. Patch by Raj Patel.
2574 Added option -m to GFS to control formatting of timestamps in log file.
2576 Added 'exit' as synonym for 'quit' in yaz-client
2578 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2579 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2580 for the new members. Patch by Ko van der Sloot.
2582 Added support for SRU POST. It is supported for content-type
2583 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2585 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2586 Instead make the library libyaz.la multi-threaded. Threading as a whole
2587 can still be disabled by configure option --disable-threads. Previosly,
2588 with older GLIBCs there were problems with MT libs under Apache. This
2589 has now been fixed a long time ago.
2591 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2594 CQL module modified to be case insensitive for relations/indexes/operations.
2596 Fixed bug in CQL transform code: incorrect value relationModifieder
2599 Added 'show all' command for yaz-client which retrieves all results
2602 Added new yaz-client, xmles, which takes a (private) OID and
2603 a document to be sent as an extended service request.
2605 Describe new yaz-client commands wait_response and set_auto_wait.
2607 Increase TCP/IP listener backlog from 3 (which I am guessing was
2608 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2609 that the socket will queue as many incoming connections as it's able
2610 to handle ongoing connections. In other words, it will never now
2611 refuse a connection that it would be able to handle merely because
2612 it's not got around to accepting() enough of the pending connections
2613 yet. This is the behaviour anyway under Linux, where the listen()
2614 argument is ignored; but not under BSD and on systems such as
2615 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2616 YAZ-based servers should now be uniform across operating systems in
2619 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2620 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2621 This allows yaz-marcdump to read large MARC batches (>2 GB).
2623 Modified all YAZ source files - except the source which is auto-generated
2624 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2627 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2628 corresponding to the existing *_setl() function. These allow option
2629 values containing arbitrary valuues.
2631 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2632 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2633 except that it returns an indicator of whether or not the sort
2634 criterion was accepted (0 for OK, -1 for invalid).
2636 --- 2.1.8 2005/06/07
2638 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2639 MARC output rather than returning "new" buffer.
2641 yaz-client warns about unknown init options.
2643 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2645 --- 2.1.6 2005/05/24
2647 Added support for SRW sort in Generic Frontend Server. Patch
2648 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2649 sortKeys - or NULL if none is provided.
2651 Fixed bug #307: It was impossible to specify indefinite/no timeout
2652 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2655 Added support for multiple languages and charsets to be specified in
2656 ZOOM. Each charset/language is separated by a blank. If negotiation is
2657 in effect in init-response, Option
2658 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2659 Code based on patch by Vasiliy Osadchuk.
2661 Fixed bug #306: infinite recursion that occurred when calling
2662 yaz_log_level_init as the first call (before other log level or
2665 Fixed bug in scan handling in front end server: if preferred-Position-In-
2666 Response was non-present, a NULL pointer referece was performed.
2668 --- 2.1.4 2005/04/26
2670 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2671 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2672 now defined for all those error codes. So instead of putting 109 in
2673 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2674 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2676 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2679 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2681 Program yaz-client now exits and produces an error message if multiple
2682 Z39.50 servers are specified on the command line (none or one allowed
2685 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2688 --- 2.1.2 2005/03/16
2690 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2692 Fixed bug #272: Preserve spacing for CCL terms.
2694 --- 2.1.0 2005/03/14
2696 Added support for virtual hosts and multiple backend servers for
2697 the YAZ frontend server. The configution is XML based and
2698 support specificition of CQL to RPN mappings and explain information.
2699 See section "Virtual Hosts" in the YAZ manual.
2701 Extended OPAC display utility. OPAC display utility renders
2702 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2703 to supplement yaz_marc_decode_wrbuf.
2705 Fixed a bug in MARC decoder that could caused it to crash for some
2706 invalid MARC records. More diagnostics and warnings where added in
2707 XML output (warnings, etc are stored in comments).
2709 --- 2.0.34 2005/02/08
2711 Fixes for UNIX domain sockets. Bug #261.
2713 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2715 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2716 Added yaz_marc_subfield_str which defines subfield lead string which is
2717 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2718 yaz_marc_endline_str which defines end of fields string used in
2719 YAZ_MARC_LINE format. Default string is newline.
2721 Experimental support for MarcXChange. This format can be produced
2722 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2723 http://www.bs.dk/standards/MarcXchange.xsd
2725 Added yaz-client commands scansize that sets maximum number of
2726 entries to be returned by scan.
2728 --- 2.0.32 2005/01/11
2730 Added support for SRW scan in yaz-client and Generic Frontend Server.
2732 * Added whereInList member to SRW Scan Term.
2734 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2736 Fixed NMEM system to return aligned blocks on the smallest boundaries
2737 that are suitably aligned for all possible types on the particular
2738 architecture YAZ is being built for.
2740 --- 2.0.30 2005/01/04
2742 Fixed numerious warnings that was issued with newer versions of GCC.
2744 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2745 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2748 Make YAZ Generic Frontend Server slightly faster.
2750 Enhance (and reduce) logging for Generic Frontend Server.
2752 Revert YAZ log system so that it flushes every write operation
2753 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2755 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2756 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2757 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2758 will effectively disable old definitions.
2760 --- 2.0.28 2004/11/09
2762 Added yaz_log_time_format which specifies log format using
2765 Added yaz_log_module_level which returns mask for a module. Value
2766 is non-zero mask a if module is enabled; zero if disabled.
2768 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2769 in include/yaz/cql.h.
2771 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2773 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2775 Fixed bug #172: RPM builds does not enable SSL.
2777 Doxyfile.in part of dist. Doxyfile generated by configure.
2779 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2780 are given and the corresponding component does not exist.
2782 Extend CCL documentation in YAZ reference. Describe r=r.
2784 --- 2.0.26 2004/10/01
2786 Fixed MARC->MARCXML conversion to properly deal with
2787 fields, subfields, indicators having non-ASCII characters.
2789 Fixed MARC->MARCXML conversion so that ASCII control characters
2790 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2793 Added YAZ GFS support for conversion from Z39.50 surrogate
2794 diagnostics to SRW surrogate diagnostics.
2796 Bug fix: YAZ GFS did not return schema in explainResponse.
2798 --- 2.0.25 2004/09/30
2800 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2801 now converts recordSchema to elementSetName as well as schema URI.
2803 Fixed bug in COMSTACK that prevented HTTP request packages from being
2806 --- 2.0.24 2004/09/29
2808 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2809 does not require white-space before and after the dash in a range, e.g.
2810 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2813 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2814 due to new GCC removing "redundant" code.
2816 Added yaz-client commands scanpos and scanstep that sets preferred
2817 position and step-size for scan.
2819 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2821 Added CCL utility ccl_qual_buf which parses one or more CCL
2822 spec lines in a buffer.
2824 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2825 of name and value - ignoring empty lines and comments.
2827 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2829 Added odr_get_element_path which returns current element path for an
2830 ODR handle. This utility is useful in error handling or user-defined
2833 Added ODR_PRINT utility odr_set_stream which is is a more generic
2834 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2835 to a write function and pointer to close function. The close function - if
2836 non-NULL - will be called during odr_destroy.
2838 Fixed bug in CCL parser where truncation char was not removed from
2839 right side when truncation=both was in effect.
2841 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2844 --- 2.0.23 2004/08/11
2846 Fix buffer overrun in CQL parser when dealing with proximity (%).
2848 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2849 to UTF-8/UCS conversion is now only based on codetables.xml.
2851 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2853 --- 2.0.22 2004/08/06
2855 Add support for more "commit changes" in ZOOM (uses Extended Services).
2857 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2860 Yet another small fix for configure of SSL.
2862 --- 2.0.21 2004/05/14
2864 Fix SSL libs for configure when --with-openssl=DIR is given.
2866 --- 2.0.20 2004/05/10
2868 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2870 SSL comstack now uses yaz.pem certificate file on server side
2871 by default. Certificate filename can be configured by calling
2872 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2874 Fix bug regarding multiple calls to ZOOM_connection_connect.
2876 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2878 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2879 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2881 ZOOM now allows inspection of X509 peer certificate for verification.
2882 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2884 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2885 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2886 as "modular" but it simplifies things.
2888 Added cs_get_peer_certificate to that returns peer X509 PEM.
2890 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2891 NULL if SSL is unavailable.
2893 Documentation about MARC decoding tools.
2895 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2897 --- 2.0.19 2004/03/30
2899 Rename CHANGELOG to NEWS to follow GNU style packing.
2901 Fix bug with missing initialization of member in init_diagnostics.
2902 This bug affects threaded version of GFS server.
2904 --- 2.0.18 2004/03/20
2906 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2909 Ensure zlib.dll is packed with Windows install.
2911 --- 2.0.17 2004/03/17
2913 Fix encoding of xsd:string to use text instead of CDATA.
2915 Fix endless loop in CQL parser with unbalanced ".
2917 Use a more compact way to store MARC-8 conversion tables.
2919 --- 2.0.16 2004/03/16 Debian only
2921 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2924 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2929 --- 2.0.15 2004/03/01
2931 Another fix for decoding of XML packed records.
2933 --- 2.0.14 2004/02/25
2935 Fixes for Chunked encoding. White space not ignored after length spec.
2937 Update NS and use default NS for SRW diagnostic elements.
2939 --- 2.0.13 2004/02/23
2941 Implement ZOOM_resultset_cache_reset which resets record cache.
2943 Implement ZOOM_resultset_sort which sorts a result set.
2945 Implement chunked HTTP transfer.
2947 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2949 --- 2.0.12 2004/02/16
2951 Added member 'schema' to bend_explain_rr structure so that backend
2952 can specify explain record identifier. Defaults to Zeerex 2.0.
2954 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2956 --- 2.0.11 2004/02/16
2958 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2961 Added init command for yaz-client which sends "extra" init request.
2963 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2964 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2966 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2968 Make ZOOM error code for "invalid query".
2970 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2972 --- 2.0.10 2004/02/05
2974 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2977 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2979 Added option -p <file> to make Generic Frontend Server to write PID file.
2981 Added option -D to put Generic Frontend Server in background on its own.
2983 Make ZOOM C recognize option "password". If unset, "pass" is used
2984 (for backwards compatibility).
2986 Fixed a bug in Generic Frontend Server that could make it crash if a
2987 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2990 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2991 Must be issued before open, in order to be in effect.
2993 --- 2.0.9-6 2004/01/12 Debian/Windows
2995 Make the SRU server more picky WRT unknown params, etc.
2997 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2999 New YAZ client command, options, that sets Z39.50 options.
3001 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
3002 options from a string of tokens (one token for each option bit).
3004 Update SRW diagnostic code messages.
3006 --- 2.0.9-5 2004/01/07 Debian/Windows
3008 Handle user defined stylesheet for SRW/SRU.
3010 --- 2.0.9-4 2004/01/06 Debian/Windows
3012 Fix bug in decoding of Content-Length.
3014 --- 2.0.9-3 2004/01/06 Debian/Windows
3016 Fix a bug with decoding of XML packed records.
3018 --- 2.0.9-2 2004/01/05 Debian only
3020 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
3022 Fix bug in SRW/SRU diagnostics decoding.
3024 --- 2.0.9 2004/01/05
3026 Fixed bug in Generic Frontend Server which could drop records exceeding
3027 preferred message size. Reported and fixed by Irina Dijour.
3029 Fixed calculation of package size for structured records in Generic
3030 Frontend Server. Reported and fixed by Irina Dijour.
3032 Fixed namespace for SRW/SRU diagnostics.
3034 Fixed SEGV in yaz-client that occured for HTTP connection errors.
3036 --- 2.0.8 2003/12/22
3038 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
3039 this version is incompatible with version 1.0 and older YAZ SRW/SRU
3042 CQL changes to reflect recent changes to the specification:
3043 * Documentation talks about context sets instead of index sets.
3044 * Documentation talks about indexes instead of qualifiers.
3045 * The CQL-to-PQF transformer's configuration file now uses
3046 "index.set.name = <attributes>" instead of the old form
3047 "qualifier.set.name = <attributes>". (Both forms are still
3048 understood but the latter is deprecated.)
3049 * CQL terms with no explicit index specified are now interpreted as
3050 cql.serverChoice instead of srw.serverChoice (which of course
3051 behaves exactly the same.)
3053 --- 2.0.7 2003/12/16
3055 MARC conversion can now generate ISO2709 output in another
3056 character set. yaz-marcdump uses this facility if you invoke it
3059 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
3060 functions from there can be used from C++.
3062 --- 2.0.6 2003/12/04
3064 Frontend server now transfers memory from decoded packages to stream
3067 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
3068 references to show up.
3070 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
3071 the ZOOM Abstract API. The older names for the same options are still
3072 also supported for the benefit of old applications.
3074 ZOOM-C supports "implementationId" and "implementationVersion" options
3075 to go along with "implementationName". These allow the user code to
3076 specify identification strings to be sent to servers.
3077 Add OID for the new ExtLite attribute set.
3079 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
3080 as requested/supplid by Ere Maijala <ere@atp.fi>
3082 For generic frontend server, reverse the order of
3083 "toolkit-supplied / application-supplied" strings sent as implementationId,
3084 Name and Version. Also, remove the spaces around the slash. This brings
3085 the GFS in line with the behaviour of ZOOM-C on the client side.
3087 Add function ZOOM_scanset_display_term.
3089 yaz-client shows scan displayTerm if present.
3091 Utility yaz-iconv is now installed by default along with the man page
3094 Extend configure check for OpenSSL to use pkg-config where available (such
3097 Incorporate patch by Morten Bogeskov which allows a Unix file socket
3098 server to specify uid/gid/mask for socket using the format
3099 unix:[user=uid,][group=gid,][umask=mask,]file=path
3100 If file= is omitted the existing format is assumed, e.g.
3102 in which case the mask is 0666 (rw for everybody).
3104 Major restructure of YAZ source. All source in libyaz is in src directory.
3105 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
3106 util (utility programs such as ASN.1 compiler, yaz-marcdump).
3108 Added man page for utility yaz-marcdump (used to be called marcdump).
3109 yaz-marcdump is installed by 'make install'.
3111 Fixed a memory leak in Generic Frontend Server that occurred when decoding
3112 of incoming package failed.
3114 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
3116 Change prototype of odr_perror: add const to message string.
3118 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
3120 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
3121 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3122 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3123 DNS lookup. There should not be any compatibility problems with this
3124 assuming that blocking=1 or 0 is used.
3126 Fix bad reference in UNIX comstack in function cs_addrstr.
3128 Fix for compilation on AIX.
3130 The generic front-end server (server/seshigh.c) now supports returning
3131 Init diagnostics to the client in User-information-field, in
3132 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3135 --- 2.0.4 2003/09/04
3137 Allow any CQL relation (not just all,any,exact,scr).
3139 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3140 that features the same UI.
3142 Implemented command update0 in YAZ client which is equivalent to
3143 update but uses old of Ext Update ASN.1.
3145 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3146 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3147 Previously no OID was used for this info.
3149 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3150 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3151 returns 'malformed search term' otherwise.
3153 SortResponse member resultCount now set to NULL in sort handler of
3156 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3159 Add three new utility functions for translating OIDs between various
3160 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3161 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3162 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3163 char *oid_to_dotstring(const int *oid, char *oidbuf);
3164 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3166 Reverted modifications for ES Update definition for z_IU0Update
3167 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3168 is back to YAZ 2.0.2.
3170 String value attributes for CCL parser.
3172 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3173 which their FirstSearch server returns in Init responses, sometimes
3174 carrying useful diagnostic information when Init fails. This has the
3175 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3176 "z39.50/oclcui.asn", where its definition is somewhat different from
3177 what OCLC document on their web-site, as required to interoperate with
3180 Support for anonymous authentication in yaz-client. Use the command
3183 * Fix the OID of the Index Data-local "admin" Extended Service from
3184 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3185 the 1000, which indicates a locally-defined OID, was a mistake.
3187 --- 2.0.3 2003/06/20
3189 Fix CCL directive @case handling so that it affects string match for
3190 both CCL keywords and qualifiers.
3192 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3193 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3194 Decoder has been updated with ASN.1 changes as listed in
3195 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3196 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3197 z_IUUpdate, remains unchanged.
3199 ZOOM_record_get may now return a record in a specific character set.
3200 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3201 "from" is the character set of record as returned by target. "to" is
3202 the character set to be returned. If omitted, "to" is UTF-8.
3204 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3206 New ODR utility, odr_getelement, which returns name of element for
3207 which encoding/decoding failed.
3209 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3210 in cases where a required element was omitted.
3212 Bug fix: some MARC8 sequences were not converted.
3214 New ZOOM option "step" which specifies number of records to be
3215 retrieved in one chunk. Used in conjunction with "start" and "count".
3217 SRW support for yaz-client. Use scheme http: to use it, e.g.
3220 yaz-client no longer does (un)intelligent character set conversions
3221 by default. Can be enabled with charset and marc_charset commands.
3223 xmalloc trace fix for 64-bit systems such as DEC alpha.
3225 Solaris 2.6 compile fix.
3227 New function, cql_strerror() translates SRW error codes, as returned
3228 by cql_transform_error(), into human-readable English strings. Used
3229 in yaz-client diagnostics when appropriate.
3231 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3232 converts it into a type-1 query which is sent to the server. This
3233 makes CQL available for use with all Z-servers, as opposed to the tiny
3234 minority that can handle CQL queries themselves.
3236 --- 2.0.2 2003/04/28
3238 New Debian package layout similar to the Redhat Package layout.
3240 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3241 and search result respectively.
3243 --- 2.0.1 2003/04/25
3245 Redhat package is now several packages: libyaz (runtime libraries),
3246 libyaz-devel (development and documentation, and yaz (utility programs).
3247 Package spec file by Morten Bogeskov.
3249 New member 'schema' in struct bend_fetch_rr which the name of requested
3250 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3251 handler MAY set this to reflect the schema of the returned record.
3253 New member 'display_term' in struct scan_entry. GFS now sets member entries
3254 and allocates scan entries to be filled by user scan handler. In previous
3255 version, entries member was allocated by the scan handler. That still works,
3256 but the GFS will ignore member display_term - assuming it was NOT set by
3257 the handler. The fact that the GFS now allocates the entries both allows
3258 for new members and makes a scan handler easier to write.
3260 Fix CQL lex buffer overflow.
3262 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3263 SRU default recordPacking is string.
3265 SRU protocol support for frontend server.
3267 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3269 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3271 Added scan for the ZOOM shell (zoomsh).
3275 * String Identifers for Schemas (Amendment 5).
3276 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3277 Old definition for schema
3278 Odr_oid *schema; /* OPT */
3283 Z_InternationalString *uri;
3284 #define Z_Schema_oid 1
3285 #define Z_Schema_uri 2
3288 * resultCount parameter to Sort Response (Amendment 1).
3289 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3291 Support for SRW 1.0 over HTTP. This is an optional feature and
3292 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3295 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3296 on the same port. SRW SearchRetrieveRequests are mapped
3297 to bend_init,bend_search,bend_fetch,bend_close.
3299 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3301 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3302 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3304 ZOOM connections are SRW based if schem http is used for hostname
3305 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3306 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3308 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3309 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3310 distance=n, order=true/false, relation=le, prox unit=word. If
3311 n is omitted, distance 1 is used.
3313 Fixed problem with C compiler include path in wrong order.
3315 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3316 on Solaris. Patch from Ko van der Sloot.
3318 New MARC decode API. All new functions operate on a yaz_marc_t
3319 handle. The most important new functions are: yaz_marc_create,
3320 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3321 decode and destroy respectively. Decoder can produce formats
3322 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3323 include/yaz/marcdisp.h.
3325 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3326 to UTF-8, UCS-32, wchar_t or Latin-1.
3328 * Prototypes for yaz_iconv_-functions moved to separate header
3329 include/yaz/yaz-iconv.h.
3331 Make a few private functions 'static' in unix.c. This prevents
3332 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3334 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3335 are set when Init Response is received.
3337 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3338 but returns diagnostic set as well.
3340 New function yaz_strerror which is a portable wrapper for
3341 strerror/strerror_r/GetLastMessage.
3343 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3344 is returned for MARC. If type is "oai", then OAI MARC is returned.
3346 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3349 --- 1.9.2 2002/11/26
3351 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3353 Fix bad race conditions on SIGTERM and terminate gracefully in
3356 Move retrieval (data1) module to Zebra since nobody seems to be
3359 Add GRS-1 render for ZOOM using same format as yaz-client.
3361 --- 1.9.1 2002/10/05
3363 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3365 Fix broken ESpec handling in data1 module.
3367 SGML reader parses comments and makes them part of the data1 tree.
3369 Added several type casts so that YAZ compiles as C++ code.
3371 ZOOM didn't handle PDU encoding failures properly.
3373 Added more Bib-1 diagnostics (approved extensions).
3375 GNU configure: better check for iconv.
3377 More portable use of accept, getpeername. Check for socklen_t. Use
3378 int/size_t if socklen_t is not defined.
3382 PQF parser rejects bad queries - including those with extra
3383 characters in them. PQF parser used to silently ignore that.
3384 Cleaner API for PQF added, which allows you to get detailed
3385 error information for bad queries (see yaz/pquery.h).
3387 Fixed bug in ZOOM_record_get for type "database".
3389 Implemented mini iconv library supporting conversions between
3390 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3392 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3394 --- 1.8.9 2002/08/20
3396 Fixed ZOOM C record cache so that preferredRecordSyntax and
3397 elementSetName is used to check for already fetched records.
3399 --- 1.8.8 2002/08/02
3401 Added three members in bend_initrequest structure to facilitate
3402 character set negotiation.
3404 Fixed a bug in frontend server that could cause indefinite
3405 loops under rare conditions.
3407 Revised character set utilities (charneg.h) so that encoding
3408 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3410 For PQF, directive @term <type> sets term type for Scan/Search.
3411 Here <type> is general, string, numeric, null. The term type
3412 is inherited - just like @attr.
3414 New call odr_set_charset that sets character set conversion for
3415 international-strings on a ODR stream. Prototype is:
3416 int odr_set_charset(ODR o, const char *to, const char *from);
3417 The InternationalString is still represented as C string in YAZ
3418 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3419 won't). On the protocol level, you can use any encoding.
3421 Support for UNIX sockets in ZOOM.
3423 Solaris recv sometimes returns errno == ENOENT. It is treated as
3424 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3426 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3427 both client and server. Code by Morten Bogeskov.
3429 --- 1.8.7 2002/05/22
3431 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3432 that they can be used directly from Visual Basic. You must recompile
3433 your windows APP if you're using ZOOM.
3435 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3436 Commands "lang" and "charset" sets language and character set respectively.
3437 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3438 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3440 Attributes from multiple CCL fields may be OR'ed rather than merged
3441 using directive "@field or". Fields are still merged by default -
3442 equivalent to "@field merge".
3444 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3447 Fixed bug in zget for parameter ExtendedServicesResponse.
3451 --- 1.8.6 2002/03/25
3453 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3455 Client displays USR.1:SearchResult-1 (hits per term).
3457 Additional Search Info for search in Generic Frontend Server.
3459 Fixed CCL parsing of "field=s".
3461 WIN32 installer - using the excellent NSIS software from nullsoft.
3463 Fixed CCL parsing of "field = - <number>".
3465 Added function yaz_marc_decode that decodes MARC for line mode
3466 display or XML (similar to that used by JZKit).
3468 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3469 Z39.50. But ISO/ILL was, however.
3471 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3472 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3474 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3475 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3477 --- 1.8.5 2002/02/03
3479 New YAZ client features: Command completion and new commands:
3480 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3481 Code provided by Jacob Poulsen.
3483 New call oid_trav, that visits all registered OIDs via callback.
3485 Function ZOOM_record_get now returns const char pointer rather than
3486 void pointer. It saves a lot of type casts.
3488 For YAZ client, command "auth" now allows you to set authentication
3489 in IdPass style. It is enabled when three tokens are given - order
3490 is user, group and password.
3492 Fix memory leaks in MARC record handling for ZOOM.
3494 New option for YAZ client, -k <kilobytes> that sets
3495 maximum record size. Similar to -k option for generic frontend
3496 server and yaz-ztest.
3498 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3500 Prefix query parser reports "fail" when bad attribute set is given.
3502 Fix in MARC decoder. Proximity logging. Fix for attribute set
3503 in scan handler for server. Patches by Shigeru Ishida.
3505 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3508 Configure option --with-openssl=<dir> now works when a directory is
3509 specified. Patch provided by Morten Bogeskov.
3511 New option for YAZ client, -u <auth>, that sets authentication.
3513 ZOOM fix: error information was sometimes "missing", since error
3514 was cleared/reset too when it shouldn't.
3516 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3518 --- 1.8.4 2002/01/04
3520 Scan for ZOOM API. New object ZOOM_scanset. New functions
3521 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3522 ZOOM_scanset_destroy.
3524 New ZOOM function, ZOOM_connection_last_event, that returns type
3525 of last event (such as "receive data", "send data", "apdu received",
3528 New ZOOM option, schema, that specifies schema for retrieval.
3530 New CCL feature. Qualifiers can be aliases for one or more
3531 other qualifiers (if more than one is given, OR is used).
3533 ZOOM uses named result sets if target supports it.
3535 Two new YAZ client commands: . (dot, which sources a script of YAZ
3536 client commands), and ! (to execute shell command.). Implemented
3539 Working on Debian packages.
3541 --- 1.8.3 2001/11/19
3543 YAZ client enables named result sets only if target supports it.
3545 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3547 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3548 with key="host" to get same result.
3550 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3551 Function Z3950_resultset_record(s) returns references to records
3552 "owned" by resultset. To become owner use Z3950_record_clone.
3554 Function z_ext_record handles Extended Services. Thanks to
3557 --- 1.8.2 2001/11/12
3559 CCL Parser fix: ignore token comma when dealing with and-lists.
3561 Documentation updates for COMSTACK.
3563 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3564 Changed prototype Z3950_records. For some functions, int parameters
3565 were changed to size_t.
3567 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3570 New MARC decode/display function, marc_display_exl, which properly rejects
3571 non-ISO2709 records. YAZ client uses it.
3573 --- 1.8.1 2001/10/29
3575 Fix bug: local attribute set wasn't set correctly in PQF strings.
3579 * Old Z39.50 codecs no longer supported.
3581 Added ZOOM C binding. See http://zoom.z3950.org/
3583 Renamed states for COMSTACKs to avoid confusion with events.
3585 Implemented cs_look and proper cs_rcvconnect.
3587 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3589 Configure detects POSIX threads on OpenBSD.
3591 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3592 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3594 When error is returned from present handler, non-surrogate diagnostic
3595 is returned in present response (and fetch handler is no longer called).
3597 * Minor adjustments to pquery parser (PQF). Token characters may be
3598 escaped by using backslash (C-style).
3600 PQF parser allows string attribute values to be specified. For @attr,
3601 non-numeric characters after the equal-sign are treated as strings
3602 (e.g. @attr 9=title).
3604 CCL trunction character may be defined (@truncation in file)
3606 * function zget_ExtendedServicesRequest sets waitAction to
3607 waitIfPossible (was wait).
3609 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3612 CCL operator names may be set in field definition files (CCL_bibset).
3613 See ccl/bib1 for an example.
3615 Fixes in ASN.1 compiler for C++ compatibility.
3617 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3618 and "op_or" to avoid conflict with C++.
3620 Fixed problem with GNU readline detection on Redhat 7.0.
3622 Added step-size for Scan backend handler.
3624 Fixed bug that made the frontend server crash when no attribute
3625 set was specified for scan.
3627 Front-end server automatically switches to original working directory
3628 when installed as an NT service. Previously -w had to be specified to
3631 Added extended attributes for retrieval module (data1), so that data1
3632 records carry d1_readXML/SGML attributes. d1_read also supports
3633 null-data rules ( <tag/>)
3635 On UNIX when POSIX threads are available, a separate library libyazthread
3636 is created. Programmers should link with that library and the yaz library
3637 when using threads. The reason for the split was that some applications
3638 on Linux, such as Apache, doesn't work well when using shared objects that
3641 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3642 (or any frontend server) in SSL mode by specifying ssl: followed by
3643 address. Only tested on UNIX.
3645 Added feature for CCL module. Virtual structure s=al or s=ol generates
3646 and-list and or-list respectively instead of phrase search.
3650 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3651 log_mask_str. This was done to avoid name conflicts with other libraries
3652 (such as other PHP extensions).
3654 Added raw OID member for preferred record syntax (request_format_raw)
3655 and returned record syntax (output_format_raw) for backend fetch method.
3657 Config file yaz-config now accepts options so that it returns specific
3658 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3660 Shared library support for UNIX using GNU libtool.
3662 * Modified backend interface. Request/Response struct's replaced by
3663 one read/write C struct. For example bend_fetchrequest and
3664 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3665 Every handler - even search has to be registered in bend_init
3666 handler. This means that the YAZ library no longer refers to
3667 external functions and it makes it possible to make the whole
3668 thing a single DLL/SO.
3670 Added Segment handler for backend server.
3672 Added Zmbol/Zebra administrative functions to YAZ client.
3674 Threaded frontend server on UNIX (when POSIX Threads are available).
3675 Starting the server with option -T enables multi-threading.
3679 Added configure option --enable-comp/disable-comp to control use
3680 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3681 located in sub directory asn.
3683 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3684 in ${exec_prefix}/bin along with the other programs yaz-client and
3687 GNU automake used to maintain makefiles.
3689 Added several OID's.
3691 Changed retrieval module so that we can load records with no abstract
3692 syntax defined. Tagpaths in these records are fully composed of string
3695 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3699 On UNIX, the generated makefile now supports a proper 'make install'.
3700 The prefix can be set via GNU configure to set the install location
3701 (default is /usr/local).
3703 * YAZ programs client and ztest were renamed to yaz-client and
3704 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3705 locations, such as /usr/bin,/usr/local/bin,etc.
3707 * YAZ Header files were moved from include to include/yaz. YAZ Header
3708 files are referred to as include <yaz/log.h> rather than <log.h>.
3709 The YAZ include path (-I ..) is therefore the same as before. Programmers
3710 should update their #include statements or use -Ipath/include/yaz
3711 instead. The main motivation for doing this change is that YAZ header files
3712 can be installed in "standard" locations /usr/include,/usr/local/include
3713 without introducing conflicts, since ALL YAZ header files are stored
3714 in subdirectory yaz (under /usr/include for example).
3716 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3717 rather than project/workspace files. We switched because project files
3718 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3721 Changed name of logging function, logf, to yaz_log, to prevent name
3722 clash with some math-log functions. The YAZ header log.h defines logf
3723 to yaz_log (#define) so there should be no incompatibilities by this
3726 Added bend_start/bend_stop handlers for server. These handler are
3727 called on start/stop of server. For windows they are called whenever
3728 a service is started/stopped.
3730 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3731 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3732 in util/yc.tcl. The auto-generated C code structures are, in a few
3733 cases, incompatible with the old decoders. There are differences in the
3734 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3735 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3736 The preprocessor variable ASN_COMPILED is defined when the compiled
3737 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3738 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3739 wish to use the old encoders/decoders you can specify --disable-yc
3742 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3743 version so that it supports both new - and old version of DB Update
3745 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3746 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3747 change. The name parameter can be set to 0 in which no name is specified
3748 for the construction. The macros odr_implicit and odr_explicit sets name
3749 parameter to zero for the construction involved. New macros
3750 odr_implicit_tag and odr_explicit_tag are similar to the others,
3751 except that a name parameter is added. For programmers' that don't use
3752 ODR they probably only need to change the call to z_APDU and z_External.
3754 Added access control facility by interfacing the TCP wrapper library.
3755 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3756 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3757 name of the daemon and enables the access control as specified in
3758 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3760 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3761 den Dool <H.M.vdnDool@kub.nl>.
3763 Added reference ID parameter to most functions in server API - refer
3764 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3766 Changed name of ccl library to libccl.a (was ccl.a).
3768 Fixed bug in decoder for Explain (Category TargetInfo).
3770 Added support for GNU readline in client. Thanks to Jacob Poulsen
3771 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3773 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3774 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3775 IMPLEMENTATION! This change was made to the development version before
3776 the ZIG decided to retract the amendment. If any users MUST be
3777 compatible with the original Update definition, PLEASE CONTACT US, and
3778 we will include a separate definition corresponding to the old Update
3779 ES. Note that because of the change to the ASN.1 of the
3780 TaskPackageRecordStructure we cannot define a single structure that
3781 will support both versions.
3783 * Added const modifier to buffer parameter for some ODR/BER encoding
3784 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3785 completeWAIS, odr_dumpBER.
3787 Fixed bug in client.c which caused a crash when a scanResponse didn't
3788 contain positionOfTerm.
3790 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3791 * will cause an error in a client if a non-YAZ target sends both a
3792 * list of Scan entries and non-surrogate diagnostics.
3794 Retrieval module enhancements. Tag sets may be typed in the reference
3795 to it. From the .abs-file the "tagset" directive takes a third optional
3796 integer type for the tag set referenced. From a .tag-file the "include"
3797 directive takes a third optional type as well. The old "type" directive
3798 in the tag set itself is still recognized but acts as the default type
3801 Backend interface change. Individual Scan terms returned from bend_scan
3802 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3803 in include/backend.h.
3805 Retrieval module enhancements. Multiple tag sets and attribute sets may
3806 be specified in abstract syntax specs. Revised the error/warning for
3807 logging messages reported by the retrieval module when reading the
3810 Object Identifier system (oid_..) changed. The API is backwards
3811 compatible but the oid-routines now allocates new OID's when needed.
3812 Raw OID's may be specified in oid_getvalbyname.
3814 YAZ now uses GNU configure to generate Makefile(s).
3816 * Minor changes in some of the member names of DeleteResultSetRequest and
3817 DeleteResultSetResponse. See include/proto.h.
3819 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3820 and added member 'languages' in TargetInfo (which was missing).
3822 Changed the way attribute sets are handled in the retrieval
3823 module. These are now cached, just like the abstract syntaxes
3826 Changed YAZ so that it links with compiled ASN.1.
3828 Added Explain-schema definitions and mapping routines. The following
3829 Explain categories have been implemented: AttributeDetails,
3830 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3832 Fixed minor bug in Windows version of Server Library.
3834 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3836 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3838 Added EXTERNAL: UNIverse Resource Report (non-standard).
3840 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3841 ENUMERATED and SET OF.
3843 * Added 'const' to some of the char pointer arguments for the
3844 functions, data1_read_node, data1_getelementbytagname,
3845 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3848 Fixed bug in data1_insert_taggeddata - the last_child member of
3849 parent wasn't initialised.
3851 * Changed data1_read_record and data1_read_node so that the supplied
3852 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3853 doesn't refer to any parts of the "SGML"-buffer.
3855 Fixed bug in server library (Windows version of statserv_remove).
3857 * Changed code so that it compiles as C++. The type definition
3858 of Odr_fun which is a member of Odr_arm was changed. The result is,
3859 that an explicit typecast is needed for the fun pointer when
3860 using Odr_arm - as in:
3861 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3863 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3865 Implemented the new structured date and time definition as approved
3866 by the ZIG. Added schemaId element to the specificTag in Espec-1
3867 (also approved at the last ZIG). Thanks to RVDM.
3869 Added some Object identifiers (RVDM).
3871 Changed the Update Extended Service (RVDM).
3873 Added command "refid" to client which specifies referenceId for
3874 the following requests.
3876 Implemented extended service handling for server. See ztest.c
3877 for an example as well as backend.h. New handlers are registerd
3878 in the Init handler.
3880 * Changed interface for sort in server.
3882 Added new members to statserv_options_block. It allows a server
3883 to read options from another source than just the command line. Thanks
3884 to Charles Woodfield.
3886 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3887 renamed to zboolean. Some C++ compilers complained about the name.
3889 Minor changes to gils.abs. Added index 's' (sort) on title
3890 and date/time-last-modified.
3892 --- 1.4pl2 1998/1/30
3894 Fixed bug in server library regarding inetd mode (-i). This bug
3895 was introduced by release 1.4.
3897 --- 1.4pl1 1998/1/29
3899 Added sort facility in client and backend server interface.
3901 Fixed problem with dependencies in Makefile(s).
3903 Fixed bugs for encoders/decoders of extended services and
3906 Implemented sub-tree feature for schemas. Sub-trees are
3907 referenced in *.abs-files. See explain.abs for an example
3908 of the use of this feature.
3910 Modified bib1.att; local attributes for ANY didn't include
3911 ANY itself (only affects use of the retrieval module).
3913 Fixed bug in plain SGML reader in function data1_read_node:
3914 tags with prefix "var" was incorrectly interpreted as variants.
3916 Added feature "sub-schemas" to enable references to - and definitions
3917 of - group of elements.
3919 * Removed member parent from type data1_element (in data1.h).
3921 Implemented function odr_nullval() that returns the value of
3924 * Removed member num_children from data1_node (in data1.h).
3926 Made NT service interface part of the server library. The
3927 function statserv_main uses the NT service when required and
3928 calls the statserv_start / statserv_close routines.
3930 Routine zget_SearchRequest and zget_PresentRequest fills
3931 resultSetName/Id member with "default" instead of "Default".
3933 Fixed memory leak in server. Request queue member wasn't freed.
3935 Fixed nmem_exit so that memory is freed.
3939 Revised the CCL parser utility to be thread safe.
3941 Added function, oid_ent_to_oid, to replace the function
3942 oid_getoidbyent, which is not thread safe.
3944 * Added nmem_init and nmem_exit to initialize and release
3945 NMEM resources. Function nmem_init should be called once in the
3946 initial thread before NMEM/ODR is used. statserv.c and client.c
3947 have been changed accordingly. The change was necessary to make
3948 NMEM thread safe. The NMEM memory pool is shared amongst threads
3949 in a process. Unix-based applications will still work fine without
3952 Added NT Services interface for the the Z39.50 (statserv) Server.
3953 Refer to the ztest.c source on the usage.
3955 Windows 95/NT port using MSVC5.0. Project files are included in the
3958 * Defined new 'global' handle for the retrieval (data1) system. The
3959 new handled, data1_handle, describes the state of the data1 system.
3960 This handle is passed as first argument to virtually all
3961 data1 related routines. The functions data1_create and data1_destroy
3962 creates and destroys a data1 handle respectively.
3964 Added ODR encode stream member to all backend request structures
3965 init, search, scan etc. This stream should be used to allocate all
3966 memory used for the response when thread safe operation is needed.
3968 Changed the comstack utility, cs_addstr, to be thread safe. The
3969 returned hostname string returned by the function is now part the
3972 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3973 function. The cs_straddr takes a COMSTACK handle as argument, so this
3974 function must be used after cs_create and before bind/connect.
3975 This function is thread safe.
3977 Moved test server to 'ztest' directory - generic server code still
3978 in 'server' directory.
3980 Made prefix query (pquery.c) utility thread safe.
3982 Added new function modifier YAZ_EXPORT to 'export' public DLL
3983 functions when using windows (see include/yconfig.h).
3985 Added definitions to the OID database (util/oid.c) (RVDM).
3987 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3989 Added call to ccl_rpn_delete in client program.
3991 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3992 release of RPN structure.
3994 Added support for C++, headers uses extern "C" for public definitions.
3995 With input from RVDM.
3997 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3998 Thanks to Ronald van der Meer (RVDM).
4000 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
4002 Added support for private extensions to the OID database
4003 (oid_setprivateoids()). Thanks to RVDM.
4005 Added optional, physical ANY (key replication)
4007 Fixed null-reference problem in GRS-1 output filter.
4009 Proximity operator added to Prefix Query Format (PQF).
4011 In test client command "base" accepts multiple databases.
4013 Fixed bug in cs_close stack that caused trouble with WINSOCK.
4017 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4019 Smallish bug-fixes in the new encoders/decoders (explain).
4021 Bug fixed in DeleteRequest.
4023 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
4025 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4027 Added SOIF syntax (using private OID for now) to retrieval module and client.
4029 Added Update extended service.
4031 Added SearchResult-1 additional info structure.
4033 Added optional CCL (ISO8777) interpreter as separate module. Available
4036 --- 1.2 1996/6/10 (1st anniversary release)
4038 Added Summary record syntax. Lightly tested.
4040 Added OPAC record syntax. Untested.
4042 Added ResourceReport service encoders/decoders. Untested.
4044 Fixed bug in z_Unit - wrong tagging on unitSystem.
4046 Fixed bug in the DiagRecs decoder.
4048 Added options for max PDU size and session timeout to frontend-server.
4050 Added documentation of query-language parsers and other supporting utilities.
4052 [frontend-server] Added Attribute set to the bend_scanrequest API.
4054 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
4055 surrogate diagnostics were generated.
4057 [retrieval] Allow multiple local values for attribute.
4059 [retrieval] Allow multiple attributes per element in .abs files. index type.
4061 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
4063 --- 1.1pl2 1996/4/10
4065 Minor changes, mostly specific to Zebra's requirements (retrieval)
4069 Repaired bug in frontend server when running multiple listening
4070 endpoints in dynamic mode.
4072 z_External() now won't break if a known, ASN.1 value comes encapsulated
4073 in an octet-string. The value will pass through unmodified in an Odr_oct.
4075 Added a bit of code to the demo client to decode & display
4076 ASN.1-structured records represented in the octet-aligned branch of
4077 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
4079 Added z_ext_getentbyref() to the ASN module. Doc updated.
4081 * Completed the SCAN definition in the ASN module. This may break SCAN
4082 code based on older YAZ-versions at compile-time. The fix is easy -
4085 * Added 'displayTerm' and OtherInformation to the TermInfo structure
4086 under the SCAN definition. Remember to initialize this, server-people.
4088 Comstack should now support the WAIS protocol in TCP/IP mode. Note
4089 that this does not extend to ODR and ASN.
4091 Comstack allows insertion of established socket (primarily for
4092 inetd-operation of servers). Doc updated.
4094 Front-end server can now start from the inetd in TCP mode. Doc
4097 --- 1.0pl4 1996/1/24
4101 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
4102 the rank and record number.
4104 Adjustments to the frontend server.
4106 Fixed diagnostic BER dumper. It ignored the file argument.
4110 Various changes to retrieval module.
4112 Changed the union discriminators of the protocol files from enums to
4113 ints paired with #defines.
4115 *Changed oident.class to oident.oclass to avoid a reserved word in C++
4118 *Changed operator in the RPN structure to 'roperator', again to avoid a
4121 Fixed problems in Explain decoders/encoders.
4123 --- 1.0pl2 1995/12/6
4125 Memory bug in log module fixed.
4127 --- 1.0pl1 1995/12/5
4129 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4131 Bug in Explain DatabaseInfo module fixed.
4133 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4137 The shift to v1.0 signals that we now consider the *core* functionality
4138 of YAZ reasonably stable (the core being more or less equivalent to
4139 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4140 tested (Explain not at all - though that will happen soonish).
4142 Minor changes to code to support Windows port.
4144 Various minor changes after we're getting to use GRS-1 & co. more.
4146 Added Espec-1 format.
4148 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4149 of the protocol and it cannot be selected when encoding (maps into 'string'
4150 when decoding). Needed to talk to some servers.
4152 Demo client can request simple element set names.
4154 Added Diagnostic Format encoders/decoders.
4156 Added simple Close handling to frontend server (no hooks for resource
4157 reporting yet), and demonstration client.
4159 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4161 --- 1.0b3 1995/08/24
4163 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4164 handled incorrectly when records were requested in the searchResponse. This
4165 will only affect you if you use the frontend-server.
4167 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4168 Test-client will ask for and print GRS1. Ztest will return dummy records
4171 Added Explain encoders/decoders to the service-level API. Untested.
4173 Added Extended Services: Item Order encoders and decoders to the Service-
4174 level API. Untested. We could use a recent copy of the pertinent bits
4175 of the ILL protocol to add those bits.
4177 Added diagnostic format 1 encoders/decoders to the service-level API.
4180 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4181 odr_cons.c, which causes a more correct output.
4183 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4184 was always set to 0 when no records were requested in the searchRequest.
4186 * Added better external-handling. This shouldn't harm old code that
4187 *encodes* externals. It can break code that looks for a
4188 'single-ASN1-type' representation, since those types that are known
4189 are now decoded immediately. Look at the SUTRS sample code in
4190 seshigh.c and client.c. Documentation updated.
4192 Handling of structured records in bend_fetchresponse. Length -1 marks
4193 structured record, type is deduced from format field.
4195 --- 1.0b2 1995/06/27
4196 Fairly quick maintenance release to add SUTRS support.
4198 Fixed handling of SUTRS records in the demonstration client.
4200 * Added format field to the bend_fetchrequest and bend_fetchresponce
4201 structures of the backend API (frontend server). When the record is
4202 returned, the value of the format field is mapped to an OID. The
4203 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4204 of the record. The special value VAL_NONE in the bend_request means
4205 that no specific format was requested by the client. Documentation
4206 updated accordingly. Test server (ztest) will return a fixed dummy
4207 SUTRS record if your client requests SUTRS.
4209 Documentation updated accordingly.
4211 You can now set external libraries and RANLIB support in the top-level
4215 First public release.
