3 record conv: 'select' return org record if no x-path match YAZ-814
5 retrieval: pick matched element-set rule YAZ-813
7 Fix crash in record conv rule 'select' YAZ-812
11 record_conv: selection by X-Path YAZ-811
12 That's a new step in record conversion system (<select path=".."/>)
14 Document record render parameters for ZOOM - including base64
18 Fix application/x-www-form-urlencoded + empty YAZ-810
19 A SEGV occurred if Content-Type was "application/x-www-form-urlencoded"
20 and empty content was supplied.
22 Fix yaz-iconv man page for typos and incorrect example. YAZ-809
24 Fail hard if Bison is not found and is needed YAZ-808
28 Enable YAZ backtrace for programs YAZ-802
30 Update NMAKE makefile to use Visual Studio 2013 along with ICU 54.1,
31 Libxml2 2.9.2, Libxslt 1.1.28.
33 Fix daemon: parent process stops before child YAZ-806
34 Try to fix the situation where parent process stops before
35 child has acknowledged it .. SIGUSR2 back!
37 daemon: log message when keepalive stops.
41 Fix yaz-marcdump segfault YAZ-801. Problem in YAZ 5.6.0/5.7.0 and
42 would make yaz-marcdump crash when from-character set was issued.
46 Dump backtrace in case of SIGABRT, SIGSEGV YAZ-787
47 New function yaz_enable_panic_backtrace which enables backtrace
48 handler for current process. The handler will call backtrace always,
49 then gdb to provide as much detail as possible.
53 When marc-8 charset is specified when decoding MARC records, yaz-marcdump
54 and ZOOM record render will inspect leader 9 and switch to UTF-8
55 (Unicode) if that holds 'a'. This changes behavior, but is considered
56 safe because only MARC21 with leader 9='a' are Unicode. YAZ-800
58 Fix cs_put may reconnect if send fails. YAZ-798
62 Fix cannot build YAZ on jessie : libgnutls-dev is gone YAZ-797
66 Extended comstack with outgoing IP YAZ-795.
67 For cs_create_host + cs_create_host_proxy the vhost may be followed
68 by a outgoing host/IP. Separator is blank.
72 Add YAZ_EXPORT to cql_transform_r fixes YAZ-793 . This issue fixes
73 linker error with yazpp on Windows.
77 Fix uri array may overflow in yaz_solr_encode_request YAZ-775
79 Fix PQF to Solr conversion may produce invalid Solr query YAZ-792
81 0 ptr reference in handling Solr response with error YAZ-791
83 Fix annoying warning about wrbuf_putc on newer GCC YAZ-789
85 Fix documentation about --installa option YAZ-788
89 daemon: properly report when receiving SIGUSR2 from child YAZ-785
93 xmalloc: throw assert for clearly invalid calls to malloc and
94 improve diagnostics YAZ-783 YAZ-784
98 Stop building debs for Ubuntu raring, quantal, oneiric.
100 CCL YAZ-781: for multiple use attributes in a specification the
101 generated RPN will perform @or on each term.
102 For spec: term u=31 u=1016
103 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
105 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
107 CCL YAZ-779: combo qualifier should allow for forward references
109 Fix buildconf.sh, automake too old on centos5 YAZ-778
110 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
111 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
112 accepts it without a warning.
116 GFS: client_query_charset conversion YAZ-777
117 This is a feature for Z39.50 clients that sends queries that are not
118 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
119 encoding given to UTF-8.
121 Echoed SRU arguments support YAZ-776
122 This is achieved with new function yaz_srw_get_pdu_e.
124 ZOOM: expire times set for redis/memcached YAZ-772
125 For both redis and memcached option --expire=seconds sets expire
126 time for a result-set/search. Default time is 600 seconds (10 minutes).
130 No [rest of output is omitted] limit for yaz_log YAZ-774
132 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
134 For ICU testing, pass -o to yaz-icu. This will test the
135 icu_iter_get_org_info function.
137 Fix null ptr reference for freeReplyObject YAZ-773
141 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
143 RPM: do not build with libmemcached support. The libmemcached library
144 on CentOS 5/6 does not work reliably for us (redis to the rescue).
146 configure: only allow libmemcached version 0.40 or later. That's the version
147 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
148 that's not an option, consider redis.
152 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
154 Fix zoom+memcached: present request out of range YAZ-767
158 CCL: add new qualifier r=omiteq which will omit relation=equals
159 for ordered relations. This should be used in combination with either
162 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
164 Solr: simplify yaz_solr_decode_response
166 Solr: use different local var for string manipulation
168 Solr: Get rid of hardcoded limit of extra_args
170 Solr: encode lucene query type YAZ-736
171 Make sure the queries are treated as traditional "lucene", because that's
174 Fix ZOOM HTTP redirect failing on Windows+Solaris YAZ-755
178 Build packages for Ubuntu Trusty Tahr 14.04 LTS
180 wrbuf_cstr: fix off by one error.
182 wrbuf_buf: make it always return non-NULL
183 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
187 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
189 zoomsh: offer option -a apdulog
190 As we're used to from yaz-client and GFS based servers.
192 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
193 existing setting apdulog takes effect.
195 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
200 Add re-entrant CQL/Solr/RPN query conversion functions.
201 The re-entrant functions are: cql_transform_r,
202 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
203 These have same functionality as cql_transform,
204 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
205 return the additional infomration as WRBUF to make them re-entrant.
207 Remove CQL to Solr conversion and base solr_transform_t on
208 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
209 data structure as cql_transform_t.
211 cql2pqf utility allows RPN to Solr conversion
213 Fix assert in ZOOM when http connect fails YAZ-757
215 --- 5.0.22 2014/04/09
217 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
219 wrbuf_cstr: make it thread safe YAZ-753
221 yaz_log_init_file may take fd=<no> to open log file at the FD given.
223 --- 5.0.21 2014/03/21
225 Offer new utility function zget_AttributeList_use_string.
227 New conversion step, solrmarc, for record conversion module.
229 --- 5.0.20 2014/03/13
231 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
232 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
235 --- 5.0.19 2014/03/10
237 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
238 The standalone ZOOM sort was completely broken since 5.0.13.
240 ZOOM: generate event Connect rather than None for partial connect
241 (in fact getaddrinfo resolving).
243 ZOOM: only supply clientIP for InitRequest. Rather than for all
246 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
248 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
249 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
250 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
252 New "Facets" section in the documentation.
254 --- 5.0.18 2014/02/27
256 Call exsltRegisterAll in yaz_init_globals, so that all applications
257 using YAZ will have EXSLT things enabled.
259 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
261 Update various URLs to the re-organized SRU pages at LoC.
263 --- 5.0.17 2014/02/26
265 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
266 introduced in 5.0.12.
268 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
269 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
270 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
273 --- 5.0.16 2014/02/25
275 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
277 --- 5.0.15 2014/02/24
279 Fix gcrypt not properly initialized YAZ-740.
281 --- 5.0.14 2014/02/19
283 Describe memcached option for ZOOM.
285 ZOOM: throw present request out of range again YAZ-739
286 Was removed in YAZ 5.0.13.
288 --- 5.0.13 2014/02/18
290 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
291 with localtime_r when threads + fork is used (such as Metaproxy).
293 yaz-config: quote some RHS values (that might include blanks)
295 zoomsh: shows SearchResult-1
297 zoomsh: sortby command
299 zoomsh: use proper list of connections and result sets YAZ-725
301 Avoid yaz_log in sigterm handler for GFS YAZ-737
302 Logging is still performed, but outside sig handler.
304 New ZOOM C feature: result-set caching with memcached. Example:
305 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
307 Remove SSL via OpenSSL support YAZ-732
308 Also deprecate two functions from comstack that aren't working with
309 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
311 Revert "Bison: use %name-prefix directive rather than -p option"
313 --- 5.0.12 2014/01/22
315 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
317 SRU GET/Solr base URLs may hold additional ?args YAZ-729
318 ZOOM option extraArgs already does this, though. It seems useful
319 when dealing with Solr targets to limit by filter, eg.
320 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
322 Remove #fragment for HTTP request encoding YAZ-730
324 Doc: Update list of DLLs/LIBs
326 Doc: update href link to Unix utils and Git.
328 --- 5.0.11 2014/01/15
330 ZOOM: fix "lost connection" problem with servers that uses both squid
331 and another proxy behind it that returns Location headers with relative
334 zoomsh: do not use readline for stdin (no tty) YAZ-724
335 Just use fgets in that case. If the user hits Ctrl-D a new-line
338 zoomsh: empty command ignored YAZ-723
339 rather than performing exit of zoomsh.
341 yaz-url utility offers option -v to enable verbose mode.
343 yaz_url uses yaz_check_location and offers verbose mode.
345 Add new function yaz_check_location.
346 This function gets an absolute URI from Location (HTTP redirect).
348 cookie API: introduce yaz_cookies_reset
350 Update cql.y for newer bison YAZ-720
351 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
352 longer supported. Instead one must use %lex-param and %parse-param .
354 --- 5.0.10 2014/01/09
356 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
359 rpn2solr: support truncation left(2), left&right(3) YAZ-718
361 Mention SRU version 2.0 in yaz-client man page.
365 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
370 Make cs_parse_host public.A
372 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
373 introduced in YAZ 5.0.6.
377 Fix buffer corruption for yaz-ztest record fetch.
381 Allow yaz-ztest to return user-defined records (one record per file).
382 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
384 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
385 Use the stream write instead of odr_printf which has a 4K tmp buffer.
387 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
391 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
392 can read and write this format. For record format JSON, yaz-ztest returns
393 MARC-in-JSON records.
395 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
396 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
400 Improve error reporting for ICU chains YAZ-707
401 Report config element+rule when ICU status is "failure".
403 ZOOM: stop fetching if present response has no records YAZ-710
404 Some targets return less records than their hit count would suggest.
405 This prevents ZOOM from continuing to fetch records if any present
406 response has 0 records in the response.
408 Ensure that GFS calls exit if any listener fails YAZ-710
409 Before, if XML config was in use, it would start the default
414 yaz-ztest: -V shows version (like yaz-client -V)
416 New iconv encoding: danmarc YAZ-692
418 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
420 daemon: only wait for immediate child rather than all children. YAZ-704
422 yaz-client: fix setting of SRU record schema. If scheme was unset, it
423 could lead to invalid memory reference.
427 yaz-ztest returns schema for MARCXML test records. SRU require that
428 recordSchema for records.
430 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
431 instead of non-surrogate diagnostic. This is a per-record failure.
433 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
434 may refer to multiple listeners now. Attribute listenref is a comma separated
437 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
438 option is given for GFS, the dirname of filename (for -f) is used
439 as prefix for options such as cql2rpn, ccl2rpn, etc.
441 Content-Type charset fixes YAZ-701 . Do not inspect charset in
442 Content-Type header for SOAP when decoding SRU. The payload (XML)
443 itself tells what encoding it is. In response, never supply encoding
444 in Content-Type. The response payload (XML) tells what it is (with no
445 encoding in XML it's UTF-8).
447 HTTP decoding: allow blanks in URL paths YAZ-700
451 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
452 and facets. Ensure recordData and recordSchema are always present in
453 record element, because they are required.
455 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
458 Simplify in a lot of places using odr_strdupn.
460 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
464 Increase various buffers in GFS's statserv_options_block
465 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
466 This change makes many type-casts redundant, and, thus simplifies code.
468 Remove last bits of WAIS support.
470 Remove member 'size' from Odr_oct.
472 Slim down the public part of 'struct odr'. Most elements are not part
473 of struct Odr_private.
475 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
476 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
477 In particular facets are supported in both client - and server side.
478 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
479 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
480 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
481 both request/response). This is what a search handler in the GFS
482 will see (regardless of whether operating in SRU mode or Z39.50).
484 Changes to the srw.h (SRU/Solr) definitions include:
485 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
486 (char*), which replace union query and query_type (int). This is because
487 SRU 2.0 supports a queryType parameter. This also means that, to carry
488 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
489 x-pquery=PQFstring (extention parameter). The extension parameter
491 - New element, packing, that has information about SRU
492 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
494 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
496 New element, packing, in Z_SRW_explainRequest.
498 New elements in Z_SRW_scanRequest, queryType and scanClause.
499 These replace query_type and scanClase untion. This is similar to what
502 --- 4.2.69 2013/10/01
504 GFS: log when closing down - at least SIGTERM YAZ-684
505 Also change formatting WRT PID logging a bit.
507 Improve display of MARC records with multi-byte subfield IDs YAZ-695
508 In some rare cases subfield identifiers are multi-byte characters.
509 This will try to deterime length of those and split accordingly.
510 This affects display in line mode as MARCXML/MarcXchange. The encoding
511 of ISO2709 is the same.
513 Change inp argument to const for yaz_read_UTF8_char.
515 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
517 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
519 Better check of marc leader info YAZ-691
520 Problem is that some systems generate MARCXML/MarcXchange with
521 funny headers. These will not work if encoded as ISO2709.
522 Some tests produce new output, due to updated warning messages
524 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
526 yaz-client: display MAB records YAZ-689.
527 Thanks for Heiko Jansen for this patch.
529 New utility z_get_HTTP_Response_server which allows both HTTP server name
530 and HTTP server URL to be given in response.
532 Debian: do not depend on obs tcl8.3.
534 Debian: do not depend on obs libicu36-dev.
536 --- 4.2.68 2013/09/23
538 GFS: pass additionalSearchInfo to search memeber search_input if
539 given. Otherwise pass otherInfo. Request for facets and other search
540 related things will be passed there in future versions of YAZ.
542 New ZOOM setting, authenticationMode, which allows authentication
543 paramters to be encoded in the URL rather than via HTTP Basic auth.
546 rpn2solr: fix nested AND/OR handling. YAZ-685
548 Add comparison routines for some Z-types, such as NamePlusRecord,
549 RPNQuery, Query, RecordComposition and OtherInformation.
551 --- 4.2.67 2013/09/19
553 Don't decode MAB as MARC. Just like we don't attempt to decode
554 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
556 CCL: allow quoted terms for date ranges. YAZ-681
558 Introduce ccl_parser_qual_search. This function makes old function
559 ccl_qual_search, from YAZ 2, available again.
561 Add yaz_facet_list_to_wrbuf. YAZ-683
563 --- 4.2.66 2013/09/11
565 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
566 schema was given for search. YAZ-675
568 Add Solr date range searches. YAZ-621
570 --- 4.2.65 2013/08/22
572 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
574 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
576 ISO2709/MARC parse most octet aligned records; not just those that
577 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
578 MARC parse more records instead of just dumping as is. YAZ-670
580 ZOOM: proper caching for variations of record schema. YAZ-671
582 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
584 --- 4.2.63 2013/07/17
588 --- 4.2.62 2013/07/11
590 New utility z_get_HTTP_Response_details - an extended version of
593 New utility yaz_url_get_error which returns error message of last
594 failed yaz_url_exec call.
596 yaz-url and url functions: allow max HTTP redirects to be controlled.
598 New functions yaz_file_glob2, yaz_xml_include_glob.
599 These functions takes a flags parameter, which, for now only controls
600 whether to fail inclusion of a non-existing file (without glob
601 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
603 --- 4.2.61 2013/06/20
605 For MARC XML parsing, allow record without leader. A fake/default leader
606 is inserted and a warning is tagged with the record.
608 ICU: fix leak in in icu_iter_get_org_info.
610 --- 4.2.60 2013/06/14
612 ICU: fix bug in icu_iter_get_org_info (un-init variable).
614 --- 4.2.59 2013/06/11
616 Implement z_HTTP_header_remove.
618 --- 4.2.58 2013/06/11
620 ICU: Disallow 0 ptrs for some ICU string utilities.
622 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
623 returns original tokens (before normalization).
625 CCL: avoid z39.58/regex truncation when not needed. Apply only the
626 conversion of those masks, when absolutely necessary.
628 CCL: configurable masking character - @mask. Default masking character
631 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
632 full response anyway, so a Transfer-Encoding header will obstruct the
635 --- 4.2.57 2013/05/15
637 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
638 picking a socket. Problem is that some systems has IPV6 support, but
639 we can't create sockets for them, so we pick AF_UNSPEC first.
641 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
642 use content_len to determine resulting Content-Length in HTTP response
643 and NOT Content-Length supplied in headers by user.
645 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
646 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
648 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
651 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
652 with big endian and unsigned char (by default).
654 --- 4.2.56 2013/04/26
656 Fix yaz-client connect (crash in 4.2.55).
658 --- 4.2.55 2013/04/26
660 Fix proxy/host problem for ZOOM that could occur if unix sockets
663 New Debian package libyaz4-dbg.
665 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
666 differently in tcpip_close.
668 --- 4.2.54 2013/04/17
670 Windows installer of YAZ includes YAZ4J as a component.
672 CQL: allow "extra terms" again, by default. Thus, the CQL parser
673 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
674 and earlier. CQL parser may operate in strict mode where queries
675 not conforming to the standard BNF are rejected (syntax error).
676 Whether the CQL parser operates in strict mode is controlled with
677 cql_parser_strict . Strict mode enabled with option -S for utilities
678 cql2pqf and cql2xcql .
680 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
682 --- 4.2.53 2013/04/10
684 New charset, MARC-8c, which is like MARC-8 but allows control characters
685 0x01 through 0x1F, except ESC to be passed through verbatim.
687 Fix a problem with duplicate sub field character in MARC output. Problem
688 happened only when output was MARC-8 encoded.
690 --- 4.2.52 2013/04/03
692 yaz-ztest: Use hash for fake hit count. Before, random number was used.
693 This is problematic for unit tests using yaz-ztest. This patch also makes
694 a hash for CQL queries. For RPN, any term with a leading digit will be
695 treated as pseudu hit count (to force any particular hit count by a client).
697 yaz-ztest: return unique MARC dummy records. Beyond record offset
698 24, the author surname is patched with offset to make all records
701 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
702 on system wide default (/proc/sys/net/ipv6/bindv6only).
703 @4 binds to IPV4 only. @6 binds to IPV6 only.
705 Update CQL API documentation a bit
707 CQL: don't accept extra terms for queries. Makes the CQL parser
708 stricly conformant to the standard.
710 --- 4.2.51 2013/02/12
712 GFS: scan handler gets extra_args from request and may return extra
713 response data . That's for SRU only.
715 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
717 --- 4.2.50 2013/01/30
719 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
721 OPACXML: sync spelling of availabilityDate in XML to that of Schema
722 opaxxml.xsd. The schema had the correct spelling of this member always.
723 The ASN.1 was mis-spelled and still is (API change) - we are
724 not changing this. However, the OPAC to XML conversion had yet
727 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
730 New function, z_ext_record_oid_nmem, which is similar to
731 z_ext_record_oid but takes NMEM rather than ODR
733 --- 4.2.49 2013/01/18
735 ICU: New conversion element 'join' which joins tokens into one
736 with a custom character given by rule attribute.
738 --- 4.2.48 2013/01/10
740 New GFS search member: present_number. This is a hint to the
741 search handler how many records are going to be fetched immediately
742 following search. There's no guarantee that it's going to be the case,
743 since it depends on hit count (for Z39.50 piggyback) and whether errors
746 Make a few functions static (private). The functions getbyte_stream,
747 ungetbyte_stream and yaz_gets are now private. They were never declared
750 yaz-marcdump: exit(5) for serious decoding errors
752 ISO2709 decoding: be more picky WRT header
754 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
755 was only used as to indicate that next-result-set-position should be
757 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
758 Based on patch from Ashley Sanders.
760 Make some functions static/private in PQF parsing. Those functions were
761 never declared in a public header and so should not be in use by
762 applications based on YAZ.
764 --- 4.2.47 2012/11/23
766 ZOOM: special options to control APDU logging.
767 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
768 logging of APDUs until "saveAPDU" option is set again. If logging is
769 already enabled the effect is that current APDU buffer is cleared.
770 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
771 logging (default behavior on new connection).
772 The APDUs sent/received can be obtained by using
773 Using ZOOM_connection_option_get(c, "APDU") or
774 ZOOM_connection_option_getl(c, "APDU", &l).
776 GFS: relay implementation_version from backend
777 From 3.0.40 and later, implementation_version from backend was
778 not used in init response at all.
780 --- 4.2.46 2012/11/15
782 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
783 mode at all. Probably never did.
785 Make a new version of ztest.pem that, at least, is not expired.
787 --- 4.2.45 2012/11/13
789 Fix description of CCL directive 'case'.
791 More tight checking of form arguments (yaz_uri_to_array). Makes
792 YAZ better at rejecting big and/or bad POSTs.
794 SRU decoding does not report more than up to 10 invalid arguments.
796 rpn2cql: less quotes in generated terms. Semantics unchanged, but
797 it's prettier this way.
799 --- 4.2.44 2012/10/25
801 New utility yaz_decode_init_diag. Defined in proto.h.
803 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
804 given for unix local socket.
805 The COMSTACK string for doing so is:
808 unix:/myfile:tcp:localhost:9999/mybase
809 unix:/myfile:localhost:9999/mybase
810 unix:/myfile:http://fakehost/mybase
812 debian: Use dpkg-buildflags in build process.
814 --- 4.2.43 2012/10/19
816 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
817 global's SRU service uses a recordPosition scheme starting from zero.
818 First record's position should be one
819 according to the standard.
821 --- 4.2.42 2012/10/18
823 Allow more namespaces for SRU. This is to allow, for example, an
824 incorrect namespace returned from server
825 http://services.igi-global.com/sru .
827 Minor fixes for compilation on Windows.
829 --- 4.2.41 2012/10/11
831 daemon: log total number of bad signals from child on stop so that it
832 is more easy to spot problems with child worker processes.
834 retrieval: empty backend name attribute omits element set
835 from being used in retrieval.
837 --- 4.2.40 2012/10/04
839 Implement Solr sort strategy "solr", similar to sru11 sorting.
840 This will implement the correct parameters on Solr requst to do
843 --- 4.2.39 2012/09/28
845 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
848 MARC: Extra/missing indicator handled for MARCXML.
849 The indicator length is given in header and is the same for the
850 whole record. If attributes ind1, ind2 are missing, then content
851 character defaults to blank. Extra indicator attributes (beyond)
852 indicator length are treated as an error.
854 Reformat: delete trailing whitespace
856 --- 4.2.38 2012/09/17
858 MARC: fix non-ASCII characters for leader. This is to ensure we can
859 generate XML in UTF-8.
861 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
862 in one node with structure word.
864 --- 4.2.37 2012/09/04
866 yaz-json-parse: JSON output may be pretty printed by using option
869 Increase default value of max message for Z39.50 Init for GFS, ZOOM
870 and yaz-client. Old value was 1 MB. New value is 64 MB.
872 --- 4.2.36 2012/08/22
874 yaz-client: don't display bogus records from SRU servers. Some SRU servers
875 return more records than given by *maximumRecords*. Skipping those in
878 record_render: simplify buffer return handling and fix at least one bad
879 memory reference, that broke the test_embed_record sometimes.
881 Allow http://user:pass@host notation for yaz_url_exec.
883 zoomsh: allow shell command to be executed. Via the system(3) call.
885 yaz_poll: Allow num_fds == 0
887 yaz-client: fix bad encoding of "itemorder item". The itemorder
888 item <no> - command forgot to use length of encoded Item Request
889 package. Error present since YAZ 3.
891 yaz-ztest: fix bad usage of session handle. Bug was introduced when
892 result sets were saved (271a9c83).
894 SRU recordPacking: guess record packing in response rather than looking
895 at the recordPacking element which, OF COURSE, changed semantics in SRU
898 Decode SRU 2.0 responses. The official namespace for responses, according
899 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
900 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
901 nature.com's server, however, usee namespace
902 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
903 we are now using a glob-expr to match up the namespace. ZOOM C and
904 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
905 I can not find a single real example showing the "real" namespace in
906 the documentation from OASIS. The namespace for requests is different
907 from responses, but this is not added to YAZ yet, when we don't encode
910 --- 4.2.35 2012/06/26
912 zoom/record_render: add support for Base64 decoding fo MARC records
913 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
914 which will decode base64 + ISO2709 marc-8 encoded material from text node
917 --- 4.2.34 2012/06/07
919 Add missing definitions ZOOM_resultset_get_facet_field_by_index
920 and ZOOM_resultset_facets_names.
922 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
925 Change APDU dump printing to avoid long leading blanks. For levels 16
926 or larger the level is shown and the indentation is truncated but
927 recursed with modula 8. This makes it still reasonable easy to read
928 - even for nested BER dumps.
930 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
931 return 0 (incomplete package) in case where the BER package was
932 considered too nested (return value of -2).
934 dumpber: lines of level 15 are not indented further. Two spaces per
935 indentation; indentation 15 or more is indented to a fixed indentation
936 and augmented with a level=<no> indication.
938 zoomsh: increase max size of command+args
940 GFS: No limit in RPN buf size in CQL to RPN conversion.
942 --- 4.2.33 2012/05/09
944 New function for daemon utility, yaz_daemon_stop .
946 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
948 --- 4.2.32 2012/04/25
950 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
951 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
953 --- 4.2.31 2012/04/23
955 YAZ daemon utility relays SIGUSR1 to child process.
957 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
958 would result in en empty database list - which in turn would result in
959 encoding failure for search.
961 Fix reading beyond string in yaz_sort_spec.
963 --- 4.2.30 2012/04/11
965 Add two new SRU diagnostics:
966 236: Access to specified database denied
967 1015: Init/AC: Maximum number of simultaneous sessions for Userid
969 Document the very useful ZOOM-C option "apdulog".
971 CQL to RPN: term may be passed through verbatim. This is enabled with
972 truncation.cql . The assumption being that the term is already CQL.
974 --- 4.2.29 2012/03/20
976 record_conv: leader spec may be given for marc element.
977 The leader spec is given as attribute leaderspec for element marc.
978 For example to convert a MARC21 record from MARC-8 to UTF-8:
979 <marc inputformat="marc" outputformat="marc"
980 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
982 record_conv: allow user-XSLT params. For example:
983 <xslt stylesheet="MARC21slim2DC.xsl">
984 <param name="myparameter" value="myvalue"/>
985 <param name="otherparameter" value="othervalue"/>
988 record_conv: fix error handling for missing marc charsets.
990 CQL: fix extra terms in wrong order.
992 --- 4.2.28 2012/03/06
994 record_conv: modify new API for conversion types. The conversion types
995 may be passed in new functions yaz_record_conv_configure_t and
996 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
998 Avoid mixed statement/variable declare; fixes compilation with Visual
1001 --- 4.2.27 2012/02/28
1003 Add non-standard SRU diagnostic: 235: "Database does not exist".
1004 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
1005 Update SRU to Bib-1 diagnostic maps accordingly.
1007 CCL: add two new diagnostics for unsupported masking. The new
1008 diagnostics are: "Embedded truncation not supported" and
1009 "Single charcacter mask not supported".
1011 --- 4.2.26 2012/02/23
1013 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
1015 --- 4.2.25 2012/01/11
1017 Build YAZ for Ubuntu Oneiric.
1019 CCL: allow parantheses for proximity operands. For example CCL query
1020 (a) % (b) is now allowed.
1022 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
1023 marked dead, rather then being destroyed. If not, the session memory is
1024 being free'd before the search/scan handler is finished. Also destroy
1025 'request' memory in request_release rather than in various places,
1026 which resulted in leaks from time to time.
1028 --- 4.2.24 2011/12/21
1030 cql_sortby_to_sortkeys: honor sort prefix.
1032 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
1033 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
1034 The rpn2cql family of functions now always returns quoted CQL terms.
1036 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
1038 --- 4.2.23 2011/12/15
1040 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
1041 sequence is treated as one. For example, &&a=b&&&c& is identical to
1044 --- 4.2.22 2011/12/05
1046 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
1047 APDUs for a connection to a WRBUF.
1049 --- 4.2.21 2011/11/23
1051 Fix cql_sortby_to_sortkeys. Completely broken before.
1053 Make CCL's @truncation work again.
1055 --- 4.2.20 2011/11/09
1057 New ZOOM connection setting: tproxy. It's like proxy, but does not
1058 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
1059 to set resolved address + port for a connection outside ZOOM itself.
1061 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
1063 --- 4.2.19 2011/11/07
1065 Fix uninitialized variable in Solr spell support (could cause SEGV
1066 for SRU response decoding).
1068 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
1069 back-end's addinfo through into the ZOOM response addinfo.
1071 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
1072 they are separated by a colon and a space rather than simply
1075 --- 4.2.18 2011/10/28
1077 Add support for Solr spell-checking/suggestions through ZOOM.
1078 If a Solr target has been configured correctly for spelling-checking
1079 and suggestions, these will now be returned on the ResultSet option
1080 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1082 --- 4.2.17 2011/09/28
1084 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1085 with a flag whether to substitute escape sequences or not.
1087 --- 4.2.16 2011/09/22
1089 Fix nmem_strsplit_escape to substitute escape char properly.
1091 New option for zoomsh -e , which makes it abort on first error and
1092 return process exit code to indicate success/failure.
1094 YAZ options utility supports special option -- which makes all it treat
1095 all following arguments as non-options.
1097 --- 4.2.15 2011/09/16
1099 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1100 searched if absolute filename is given.
1102 Fix conv_xslt() error-reporting when stylesheet is not found.
1103 (The value of fullpath is meaningless in this situation.)
1105 --- 4.2.14 2011/09/07
1107 Fix problem in CQL sort node creation: un-initialized memory.
1109 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1110 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1111 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1114 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1115 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1117 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1118 will make it possible to use both single-character mask (#) and wildcard (?)
1119 in CCL . Throw diagnostic for left truncation because that is not supported
1122 --- 4.2.13 2011/09/01
1124 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1125 cases using escapes (\-sequences) and masking.
1127 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1128 would result in a read one byte beyond string.
1130 rpn2ccl may use Z39.50 masking for terms (t=z).
1132 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1134 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1135 not --cppflags (which seeems like an error in icu-config).
1137 --- 4.2.12 2011/08/27 RPM package only
1139 cql2ccl: fix conversion of terms: operator characters were not
1142 --- 4.2.11 2011/08/25 RPM package only
1144 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1145 CCL parser will map both # and ? to their regular expression
1146 quivalents (. and .*).
1148 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1149 of reserved CQL characters.
1151 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1152 is, so that they are passed through.
1154 --- 4.2.10 2011/08/24
1156 ZOOM SRU mode: more aggressive re-connect.
1158 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1159 made available as a utility function, declared in <yaz/logrpn.h>
1161 rpn2cql_structure() supports proximity nodes (except that the Type-1
1162 proximity node's "exclusion" binary is ignored, as there is no way to
1163 express that in CQL). Fixes bug #4564.
1165 --- 4.2.9 2011/08/18
1167 Fix SEGV that could occur if set command of zoomsh was given without
1168 value (2nd argument).
1170 Fix SEGV that could occur if unsupported transport was given for
1171 COMSTACK - say https (when SSL was unavailable).
1173 Build yaz-url on Windows too.
1175 --- 4.2.8 2011/08/11
1177 New utility to get web content. Header is url.h. A command line tool
1178 yaz-url is part of the distribution and packages.
1180 Fixes for SSL COMSTACK (when gnutls is in use).
1182 New functions yaz_base64{encode,decode}. Header is base64.h.
1184 --- 4.2.7 2011/08/03
1186 ZOOM C includes HTTP response buffer as additional info if it fails
1187 to decode the SRU response.
1189 Make wrbuf_json_puts available.
1191 --- 4.2.6 2011/07/28
1193 zoom: throw diagnostic for invalid value for option "sru". Before a
1194 bad SRU request was sent.
1196 Adding new utility wrbuf_vp_puts.
1198 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1200 --- 4.2.5 2011/07/21
1202 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1203 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1204 redirect was used at the same time.
1206 MARC line mode decoding: be less picky about length given - first
1207 5 digits of header that is.
1209 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1211 Changes to decoding of SRU records: a record with recordPacking=xml is
1212 modified with a new root element <yaz_record> if the recordData contains
1213 multiple children elements. This is to make the record XML parseable
1216 RPN to Solr conversion: encode special characters.
1218 Generic Frontend Server: fix uinitialized member, stepSize.
1220 --- 4.2.4 2011/06/21
1222 Fix a bug in SRU decoding of records.. The database records stored
1223 had un-initialized memory, but it would only be seen with yaz_record_render
1224 and type_spec="ext" .
1226 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1228 --- 4.2.3 2011/06/17
1230 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1232 --- 4.2.2 2011/06/10
1234 Add new utilities to convert from CQL to CCL . These utilities have
1235 prefix cql_to_ccl defined in cql.h.
1237 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1238 lead to memory heap corruptions when ICU utilities were in use.
1240 --- 4.2.1 2011/06/07
1242 Make compilation work without Libxml2.
1244 yaz-client: remove redundant blanks in display of searchResult-1 term
1247 --- 4.2.0 2011/05/18
1249 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1250 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1252 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1253 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1254 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1255 Note that the CQL sortby spec is only converted when the GFS is already
1256 converting from CQL to RPN (cql2rpn element).
1258 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1259 specify whether to collapse delimitors or not. The existing nmem_strsplit
1260 do collapse (collapse parameter = 1).
1262 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1264 Rename internal func yaz_use_attribute_create. While non-static, this
1265 function is not declared in a public header.
1267 --- 4.1.7 2011/03/15
1269 Add -lCrun when linking with ICU on Solaris.
1271 More quicks character set conversions for OPAC records.
1273 --- 4.1.6 2011/03/10
1275 fix problem with record_render: records were converted (character set
1276 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1278 --- 4.1.5 2011/03/08
1280 SRU: add methods for handling DADS SRU-proxy facets.
1282 Separate OPAC record character set for ZOOM_record. yaz_record_render
1283 allows a character set given as charset=from/opacfrom,to where 'from' is
1284 the character set of a bibliographic record, 'opacfrom' is character set
1285 of OPAC record and 'to' is the target character set.
1287 --- 4.1.4 2011/02/21
1289 yaz-client: show may XML format records. Command show followed by 'format'
1290 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1293 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1296 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1298 --- 4.1.3 2011/01/27
1299 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1301 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1302 this package can be distinguished from other vendors.
1304 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1305 as determined by configure
1307 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1309 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1310 returns no error and no record, the present request is considered
1311 partial (only a subset of the records could be returned by backend), and
1312 so it is appropriate to set Present Status to partial-4.
1314 --- 4.1.2 2010/11/02
1316 Move yaz-config man pages to section 1.
1318 More documentation about Solr.
1320 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1321 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1322 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1323 peers on some Linux systems. However, in general that does not work
1324 so YAZ can not rely on that to work. Debian changed behavior in this
1325 respect from Debian lenny to Debian squeeze (still testing as of Oct
1327 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1329 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1331 --- 4.1.1 2010/10/05
1333 Fix yaz-config output: echo_source not set correctly by configure.
1335 --- 4.1.0 2010/10/05
1337 Solr Web Service support for yaz-client and ZOOM.
1339 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1341 --- 4.0.12 2010/08/17
1343 Z39.50 facet support. Facet specifications are passed for search in
1344 other-information with ASN.1 as defined in facet.asn and OID
1345 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1346 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1347 3 is limit (number of entries to get in response). yaz-ztest returns
1348 dummy facets if a client asks for them.
1350 --- 4.0.11 2010/07/09
1352 CCL fixes: bug 2895 and bug 3539.
1354 GR1-display: add comma in display - was removed by mistake in
1357 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1359 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1361 --- 4.0.10 2010/06/18
1363 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1364 result set from a connection. The result set will be on its own
1365 thereafter; no operations on it will perform retrievals from a target.
1366 Only cached copies are returned.
1368 ZOOM C:fix case for HTTP servers responding with Connection:close.
1369 Ensure that if there is a current task it is resumed (like fetching
1370 more records in a result set) . Bug #3484.
1372 PQF parser: use odr_atoi for Odr_int (not atoi)
1374 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1375 values that contain any non-digits are treated as string attributes
1376 (previously decoding only checked for leading character ([0-9]). PQF
1377 encoding: attribute string values are not surrounded by double-quotes.
1379 --- 4.0.9 2010/05/21
1381 New utility for managing threads - thread_create.h.
1383 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1384 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1385 but YAZ' implementation do.
1387 Fixes for yaz_cond-functions on Windows 7.
1389 DLL export more symbols.
1391 zoomsh: show record do NOT render opac.
1393 Remove *.la files from Debian and RPM packages.
1395 --- 4.0.8 2010/05/11
1397 Debian package libyaz-dev depends on libgnutls-dev again (was
1398 removed in YAZ 4.0.6, but due to Libtool it is still needed
1399 even though yaz-config do not list libgnutls libs).
1401 ZOOM: Use only one WRBUF for returning string results for
1402 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1404 ZOOM: ZOOM_connection do not use a shared pointer to
1405 ZOOM_resultset after ZOOM_resultset is destructed by
1406 user. Reverts to YAZ 4.0.4 behavior.
1408 --- 4.0.7 2010/05/04
1410 record-conv: fix problem with at least one XSL conversion -
1411 due to probably incorrect usage of XML XSL documents.
1413 --- 4.0.6 2010/04/29
1415 Fix yaz-config for static mode and the use of SSL (gnutls).
1417 --- 4.0.5 2010/04/29
1419 Forward decl timeval struct in mutex.h and gettimeofday.h.
1421 yaz-config: fix 'static' mode linking.
1423 --- 4.0.4 2010/04/28
1425 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1426 are wrappers for pthreads or Windows. For Windows these are put in
1427 a separate DLL: yaz_cond4.
1429 libyaz.la (whole source) is compiled with thread. If thread support
1430 is enabled enabled, all source of YAZ is compiled with treading support.
1431 This allows core utilities such as yaz_log to use thread facilities.
1432 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1433 thread utilities. This commit moves mutex utilities (mutex.c) from
1434 libyaz_server.la to libyaz.la.
1436 yaz-json-parse displays leading text until error.
1438 --- 4.0.3 2010/04/09
1440 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1441 patch from Giannis Kosmas.
1443 SRU: no longer URL encode SRU database. The URL for an SRU server is
1444 a URL and such is alreeady encoded - at least when given with leading
1445 http:// or https://. This reverts behavior to YAZ 3.0.50.
1447 Support for new MARC XML notation TurboMARC which like MARCXML is a
1448 complete representation of MARC/ISO2709.. This one, however, is more
1449 compact and allows for faster processing with XSLT. TurboMARC can be
1450 used in the marcdisp.h API, from the yaz-marcdump utility and from
1453 yaz-ztest can be configured - via the database - to perform certain
1454 delays when it performs operations search, present and single record
1455 fetch. This allows testers to make yaz-ztest act as a real or even slow
1456 Z39.50 server. Refer to the yaz-ztest man pages for details.
1458 --- 4.0.2 2010/03/09
1460 wrbuf_destroy allows NULL WRBUF passed to it.
1462 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1464 Add ZOOM_connection_close.
1466 No fixed size buffers for ZOOM shell - bug #3257.
1468 tstodr: make it work on s390 platform.
1470 New icu iterator-functions. The new icu_iter-functions makes it possible
1471 to use ICU chains from many threads.
1473 yaz-client: better syntax check for show command.
1475 --- 4.0.1 2010/01/26
1477 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1480 New simple local-file XML include facility which allows file glob-patterns.
1481 Refer to yaz/xml_include.h.
1483 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1486 ZOOM_record_get supports new parameter "format" which makes it format XML
1489 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1490 JSONText in ECMA-262) is JSONValue, not JSONObject.
1492 --- 4.0.0 2010/01/20
1494 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1495 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1497 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1498 POSIX/Unix builds .so with major version 4.
1500 Remove old LOG_-defines from log.h. They have been obsolete and
1501 undefined by default for the last 5 years.
1503 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1505 GFS: Remove socket (int *fd) from search_rr handler. The socket
1506 descriptor ptr is a facility that allowed a search handler to supply
1507 a socket which would serve as a callback - when search was complete.
1508 This facility has now been in use for years.
1510 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1511 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1512 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1513 returns 'const char *' rather than 'char *. The returned string is
1514 read-only and should not be modified by applications. COMSTACK cs_close is
1515 now a void function - it no longer returns int. No applications check for
1516 the value and the implementations has always returned 0.
1518 ZOOM: use size_t for scan hit counts and str size. Functions
1519 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1520 occ (hit count) and len (string length) are now of type size_t pointer
1521 rather than int pointer. This is to be able to represent large hit counts
1522 and to also just to use the proper type for string length (strlen result).
1524 New JSON parser. Refer to include/yaz/json.h .
1526 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1527 Used to be int in some cases. Many wrbuf_-functions used to return an int
1528 indicating some length.. These return values were never used. And so they
1531 ODR: odr_malloc, odr_total now takes size_t for size.
1533 clone_z_type: fix leak; occurred for encoding failures.
1535 --- 3.0.52 2009/12/03
1537 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1538 bug was introduced in 3.0.51.
1540 --- 3.0.51 2009/12/02
1542 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1544 tcpip comstack: fix leak for getaddrinfo.
1546 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1547 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1548 Decoding of SRU "path" database is performed by private function
1549 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1550 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1552 yaz-client: honor base command for SRU. Change when database setting
1553 is applied for SRU and ensure it is kept when a connection is reset.
1554 Change also the way errors are displayed or SRU (decoding of packages).
1556 --- 3.0.50 2009/11/02
1558 Add support for extra request / response data for SRU codecs and GFS.
1559 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1560 for extra data response buffer and length. For the GFS, both request
1561 and response data (XML) is carried in extra_args and extra_response_data
1562 for the search handler. Patch by Ko van der Sloot.
1564 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1565 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1566 10010). This fixes bug #2113.
1568 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1569 cmdfile included a 'quit' command that would result in a memory violation.
1571 --- 3.0.49 2009/10/01
1573 Make a number of functions defined in xmlquery.c static. These have
1574 never been declared in a public header file (yaz/xmlquery.h) and was
1575 made public by mistake.
1577 Improve speed of character conversions (iconv utilities). This makes
1578 conversions from MARC-8 faster.
1580 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1581 unless type desired is "raw". This will prevent type "xml" from
1582 returning ISO2709 .. Which obviously can not be XML parsed.
1584 Fix memory leak in ZOOM that would occur if option apdulog was used
1585 on a re-used connection.
1587 Frontend server logs HTTP requests.
1589 Frontend server now sends Z39.50 close when it times out (sesssion has
1590 been idle for too long). Versions 2.0.30 and earlier also sent close.
1591 But due to a mistake this was disabled in all versions after that, i.e.
1592 the server would just close the socket immediately.
1594 yaz-client emits a better message when receiving an unrecognised
1595 userInformationField.
1597 Skip zero-length subfields when decoding ISO2709. This rare case happens
1598 if a record has two FS characters in a sequence. Without this patch
1599 there would be a reference beyond char array in using_code_len fragments
1602 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1604 --- 3.0.48 2009/08/28
1606 The show command offered by the zoomsh command now takes a 3d optional
1607 parameter type which is what is passed to ZOOM_record. If the type
1608 argument is omitted, "render" is used.
1610 RPN to CQL conv may use USE string attributes (bug #2978).
1612 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1614 --- 3.0.47 2009/07/08
1616 Function yaz_xml2query allows a diagnostic element in the PQF XML
1617 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1618 code and additional info respectively.
1620 The BER BOOLEAN is now the integral type Odr_bool which still happens
1621 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1622 typedef'd to Odr_int. This is still an integral 'int', but it may be
1623 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1624 ASN-1 compiler as well as programs has been updated to use the new types.
1626 --- 3.0.46 2009/06/08
1628 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1629 only the bibliographic record was rendered. For type=opac, an OPAC
1630 record is only returned if it is present.
1632 iconv: small fix for encoding of advancegreek.
1634 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1636 yaz-client: option auto_reconnect=on really reconnects.
1638 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1640 server: avoid null ptr ref for for yaz_poll errors.
1642 build: fix RPM build for RHEL 5.3.
1644 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1646 --- 3.0.45 2009/03/31
1648 Fixed bug #2709: TCP connect returns Invalid argument.
1650 Fixed compilation for mingw.
1652 Honor charset for raw records (ZOOM_record_get).
1654 Fixed use of errno for threaded mode that was seen on Solaris 10.
1656 Fixed argument passing with blanks in value for Windows Service.
1658 Disable YAZ' own log rotate by default (no 1 GB limit).
1659 The variable l_max_size which specifies the log file limit is set to 0
1660 (DISABLED): This is due to the fact that YAZ is most often deployed using
1661 logrotate. Also YAZ can not perform log rotate because of unsufficient
1662 permissions (setuid).
1664 --- 3.0.44 2009/02/17
1666 List supported encodings in man page for yaz-iconv.
1668 Fixed missing SSL libs for --libs output
1670 Re-established OID record syntax application-xml. Nobody should use it
1671 but we don't want to change soname because of this symbol being absent.
1673 --- 3.0.42 2009/02/02
1675 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1677 Added member named_result_sets for init handler struct for the GFS. This
1678 allows a server to disable named result sets.
1680 Removed OID record syntax application-xml.
1682 Added support for rule-based transliterator for ICU wrapper of YAZ.
1684 Fixed bug #1902: yaz-icu XML output.
1686 Make YAZ checks Emacs friendly.
1688 BITSTRING value shows value. Bug #2346.
1690 ISO2709 decoding: skip control characters from indicator data.
1692 Omit sort key by default in yaz-icu's output.
1694 Allow combined single char options (again) for YAZ' options function.
1696 Utility yaz-marcdump got option to display YAZ version (-V).
1698 Allow YAZ to use ICU 3.4.
1700 Added new ICU test case which illustrates removal of diacritics.
1702 --- 3.0.41 2008/12/29
1704 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1706 --- 3.0.40 2008/12/29
1708 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1711 Fixed bug #2352: yaz-marcdump crashes for certain record.
1713 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1715 Added support for Danmarc2 to UTF-8 conversion.
1717 Added support for ISO5426 to UTF-8 conversion.
1719 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1720 implementation version.
1722 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1724 --- 3.0.38 2008/11/10
1726 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1727 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1729 ZOOM C now interprets databaseName option for ZOOM connection as path
1732 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1734 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1736 Dummy Libxml2 types no longer defined in headers of YAZ'.
1738 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1741 --- 3.0.36 2008/09/26
1743 Various ODR chapter fixes.
1745 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1747 Added missing source for Windows compilation, mutex.c.
1749 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1751 For SRU connections in ZOOM all records up to "count" are now fetched.
1753 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1754 in Windows due to bad error handling for Libxml2.
1756 Added facility for sending arbitrary records (ASN.1 any) using
1757 ZOOM C's Extended service update. Patch by Sam Reynolds.
1759 New options for ZOOM C's connection, logapdu which makes ZOOM log
1762 --- 3.0.34 2008/06/18
1764 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1766 --- 3.0.32 2008/06/12
1768 Fixed memory violation that could occur when decoding UTF-8. This bug
1769 was only present in 3.0.30 of YAZ.
1771 --- 3.0.30 2008/06/06
1773 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1774 GNU TLS is used by default (if found).
1776 yaz-ztest returns OPAC records if a client asks for OPAC.
1778 Improved speed of MARC-8 encoding.
1780 Added support for lossy and loss-less MARC-8 encoding.
1782 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1784 Added new Windows Service wrapper (sc).
1786 yaz-client's itemorder command may now send a file.
1788 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1790 Added new function yaz_log_xml_errors.
1792 Allow (but warn) unknown XML attributes in MARCXML parsing.
1794 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1796 The UTF-8 to MARC-8 conversion now uses a different set of characters
1797 for Greek symbols. Bug #2120.
1799 --- 3.0.26 2008/02/21
1801 Added yaz_daemon (daemon.h).
1803 Fixed bug #2068: pkg-config trouble
1805 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1807 --- 3.0.24 2008/01/28
1809 Document --with-xml2 option.
1811 Added OPAC XML XSD (etc/opacxml.xsd).
1813 Allow glob mask for name attribute in retrieval element for the
1814 generic frontend server's retrieval facility.
1816 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1817 except POLLIN/POLLOUT.
1819 Fixed error handling in cs_listen. Bug #2037.
1821 --- 3.0.22 2008/01/20
1823 Fixed version in yaz/yaz-version.h.
1825 Fixed bug #2027: Crash when closing connection.
1827 Changed configure so that ICU support is only enabled if only ICU
1828 and Libxml2 is available (because the ICU chain is XML based).
1830 --- 3.0.20 2008/01/15
1832 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1833 is built. Only this DLL depends on the ICU runtime.
1835 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1836 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1838 Changed license of CCL module to 'Revised BSD'. After consultation with
1839 remaining members of the original EUROPAGATE consortium, we are re-issuing
1840 the CCL module without a separate license. The software was developed by
1841 Index Data as part of a research project. The special license was included
1842 to help feed usage information back to the project consortium to support
1843 project evaluation. At this time, the project consortium has long-since
1844 disbanded, and the majority of the original principals have retired. At the
1845 same time, we have significantly modified the software during the following
1846 years, to the point where very practically no original code remains. To
1847 simplify re-use of the software, we have contacted those members of the
1848 consortium who could be reached, and agreed to re-issue the module as a
1849 proper part of the YAZ package.
1851 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1853 CQL closer to being version 1.2 compliant. CQL also allows free-form
1854 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1857 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1858 bug could make Extended services handling crash in the ZOOM layer. This
1859 bug was only present in YAZ 3.0.18.
1861 --- 3.0.18 2007/12/19
1863 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1866 yaz-marcdump reads and writes collection wrapped records.
1868 Handle OPAC for record conversion module.
1870 Fixes for ICU wrapper.
1872 Allow ICU libs to be controlled with --with-icu .
1874 --- 3.0.16 2007/11/12
1876 Added yaz_poll which is a wrapper for select/poll. When poll is available
1877 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1878 sockets to be in use.
1880 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1881 functionality through an XML based configuration (ICU chain). This system
1882 is useful for search facilities such as Pazpar2 and Zebra that needs to
1883 perform tokenization of indexed material. The ICU code in a separate
1884 library libyaz3_icu.a.
1886 Added HTTP tunnel facility for COMSTACK, bug #1752.
1887 This is a facility that allows a Web proxy, such as squid, to tunnel
1888 Z39.50 traffic. This facility is "transparent" to must applications
1889 using YAZ. It's enabled by using pseudo transport connect: followed by
1890 the proxy address, followed by command, then follwed by he regular
1891 "virtual" addresss. For example,
1892 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1894 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1896 --- 3.0.14 2007/09/21
1898 Fixed bad memory reference in ZOOM_record - cuased by member not being
1899 initialized. This was a problem only in YAZ 3.0.12.
1901 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1902 fields were not removed.
1904 Changed the way C code is generated from codetables.xml. Made a MARC-8
1905 conversion trie for each characterSet section rather than codeTable.
1906 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1907 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1909 --- 3.0.12 2007/09/12
1911 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1912 from ZOOM_record_error).
1914 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1916 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1918 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1920 Better SRW-to-Bib-1 diagnostic mapping.
1922 ZOOM C and yaz-client announces SRU version 1.2 by default.
1924 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1927 Fixed in yaz_sru_decode to allow other version than 1.1.
1929 --- 3.0.10 2007/08/22
1931 Added support for SRU scan for ZOOM.
1933 Added support for the use of the older versions or Extended Service
1934 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1935 set to the version , 1=first, 2=second, 3=third. The third version is
1936 what ZOOM C has used so far. And that, obviously, is the default.
1938 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1939 therefore in Zebra and in SimpleServer-based applications). The new
1940 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1941 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1942 which is passed into the back-end search callback function.
1944 Added support for HTTP Basic authentication in clients: the SRU/W
1945 codec encodes the username/password elements of the PDU structure
1946 appropriately, and these may be set using the "user" and "password"
1947 options in ZOOM-C applications (the same options that are used for
1948 Z39.50 authentication).
1950 --- 3.0.8 2007/06/25
1952 Fixed bug #1208: SSL appears to be broken in ZOOM.
1954 Fixed bug #1206: Libxml2 include path weirdness.
1956 Added oid_name_to_dotstring.
1958 Allow elementSetName to be specified for ZOOM C record update.
1960 Allow waitAction to be specified for ZOOM C based for Extended Services.
1962 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1963 syntax OID. Bug introduced in YAZ 3 series.
1965 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1967 --- 3.0.6 2007/06/06
1969 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1970 directory. yaz-client now reads commands from file given by option -f
1971 if specified; then tries to read .yazclientrc in current directory.
1972 Failing that, it reads .yazclientrc from user's home directory.
1974 Added support for correlationInfo Note and ID for Record Update via
1977 Added yaz-client command querycharset which specifies character set for
1978 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1979 (termListAndStartPoint).
1981 Charset ISO5428:1984 is an alias for ISO5428-1984.
1983 Implemented a way to perform scan in a result set using Z39.50. This
1984 is achieved by attaching the result set name in the characterInfo
1985 (type InternationalString) of OtherInformation in the Scan Request PDU.
1986 The result set is identified in the otherinformation by the new OID:
1987 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1988 This allows for scan in result set and faceted search . Zebra did some
1989 of this in the APT term using attribute type 8 and value being result
1990 set. Using the OtherInformation approach for this is cleaner and easier
1991 to work with in proxies and the like. This facility can be used in
1992 yaz-client using new command setscan which takes a result set as first
1993 argument, start position (APT) as second.
1995 Changed decoding of SRU XML packed records to deal with servers that
1996 have recordData with XML data with multiple root nodes. Also make
1997 comparison for recordPacking case insensitive. Again, one server
1998 returns "XML" where others return "xml".
2000 For SRU responses allow Content-Type application/xml as well as text/xml.
2002 --- 3.0.4 2007/05/21
2004 Fixed bug in character set conversion of BER strings. Bug introduced
2007 --- 3.0.2 2007/05/08
2009 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
2011 For OID class, use oid_class consistently.
2013 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
2016 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
2017 character set for bibliographic information interchange". By Giannis Kosmas.
2019 Added documentation on new OID API.
2021 --- 3.0.0 2007/05/02
2023 Changes to generic frontend server interface: added new member
2024 'query_charset' for bend_initrequest structure. A backend init handler
2025 should set this member to its native character set for query terms.
2026 When defined, the frontend server logic will announce this character set
2027 to a client if the negotiationModel bit is set by the client. All server
2028 implementors are encouraged to specify this. If a backend server does not
2029 specify this a warning is issued using yaz_log(YLOG_WARN,..).
2031 Added CCL utility to remove terms (stop words) from resulting RPN
2032 tree. This is handled by functions with prefix ccl_stop_words_ .
2034 New ZOOM C option, "rpnCharset", which allows client-side conversion of
2035 terms in RPN queries.
2037 Clean-up the CCL API. Moved some internal structures from ccl.h to
2038 private header cclp.h. Changed ccl_parser_create so that a Bibset must
2039 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
2040 This is replaced by ccl_parser_find_str which takes a string instead.
2042 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
2043 libyaz.la is the core of YAZ except the generic frontend server and
2044 does not depend on POSIX threads anymore. libyaz_server.la is the
2045 generic frontend server facilities and uses POSIX thread functionality
2046 if available. The libyaz.la no longer depends on POSIX threads because
2047 the number of global structures is limited. NMEM no longer re-uses blocks
2048 between threads ; it simply free's memory immediately but allocates in
2049 "large" chunks as usual. We don't expect any performance penalties
2050 because of this. The yaz_log system is still using a global log_level so
2051 caution must be taken when modifying it with yaz_log_init_.. +
2052 yaz_log_mask_str. This, however, should not cause any trouble because
2053 these functions are called during initialization of application code
2054 anyway. `yaz-config --libs server` returns libs for server applications;
2055 `yaz-config --libs` returns libs for non-server applications.
2057 New OID database - with public definitions in oid_db.h. Removed old OID
2058 database including the head oid.h and definitions such as enum oid_value
2059 and struct oident. The new OID database uses the same string names as
2060 before but the 'protocol' is gone. There are now only two representations
2061 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
2062 converts from string to OID; functions with prefix yaz_oid_to_string
2063 converts the other way.
2065 Change to emit_term() in CQL-to-PQF query translation: when a term has
2066 the /regexp relation modifier, do not process it for leading and
2067 trailing "^" and "*", which have quite different meanings in regular
2070 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2071 write handlers no longer carries a 'last' parameter. This will make
2072 yaz_iconv flush "less" characters. A flush is performed by call to
2073 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2075 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2076 removed, because function yaz_query_to_wrbuf does the same.
2078 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2079 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2081 Deprecated MARC utility functions removed.
2083 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2086 Branch split: YAZ_2_1_55_branch
2088 --- 2.1.54 2007/03/16
2090 Fix to ZOOM-C so that transparent reconnection is properly handled on
2091 connections that are in asynchronous mode.
2093 Fixed compilation on OpenBSD 4.0.
2095 Large strings in GRS-1 records are now properly displayed in yaz-client.
2097 Added character conversion support for "advancegreek"; based on patch from
2100 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2101 sequence is met. Before the error was not set so it would be unknown.
2103 Adjust yaz-marcdump MARC reader so that it skips until record separator
2106 --- 2.1.52 2007/03/07
2108 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2109 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2110 fd_set structure used as a bitmask for the FDs to be selected on.
2112 Using ACX_PTHREAD macro to check for POSIX threads.
2114 Fixed have-vsnprintf check.
2116 --- 2.1.50 2007/02/23
2118 Fixes for configure on BSD. Bug #900.
2120 Added snprintf/vsnprintf wrappers for systems that don't have
2121 limits (heavens forbid).
2123 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2124 created before all previous tasks were completed and removed from the
2125 task queue, the new task could be removed by a mistake.
2127 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2129 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2131 Fixed bug #832: Problem with MARC/charset in yaz-client.
2133 Fixed bug #668: save command line history for yaz-client.
2135 Fixed bug #830: pkg-config support.
2137 --- 2.1.48 2007/01/23
2139 Extended ZOOM result set options with two options that may be read by
2140 a client: resultSetStatus and presentStatus with values as specified for
2142 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2144 Fixed bug #827: Using SSL fails on Debian etch.
2146 Fixed bug #826: Weird looking chars for set of MARC records.
2148 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2149 that is treated as an ItemOrder with itemRequest being an XML document
2150 external. The value of "doc" is the content.
2152 Extended the GFS search facility. New member of bend_search_rr
2153 'estimated_hit_count' signals that hits is known to be an estmate
2154 (higher or lower than real hit count). New member 'partial_resultset'
2155 signals that the search was partial (hit count is lower or equal than
2156 real hit count). For Z39.50, the information is stored in resultSetStatus
2157 member of SearchResponse APDU. For SRU, the information is signalled
2158 via SRU diagnostic 59: "Result set created with valid partial results
2161 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2163 --- 2.1.46 2007/01/13
2165 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2167 Added ZOOM_connection_peek_event.
2169 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2170 the following new functions:
2171 ZOOM_event_nonblock, ZOOM_connection_process,
2172 ZOOM_connection_get_{socket,mask,timeout},
2173 ZOOM_connection_fire_event_{timeout,socket}.
2174 The existing blocking event handler, ZOOM_event, is a wrapper for the
2175 + blocking ZOOM_event_sys_{poll,select}.
2177 Implemented function ccl_xml_config which parses XML version of CCL
2178 configuration (bug #798).
2180 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2182 Added timings utility (yaz/timing.h)
2184 --- 2.1.44 2007/01/03
2186 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2189 Fixed bug #779: Rotation of apdu.log fails.
2191 Fixed for character set conversions:
2192 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2193 Honor G1 set in MARC-8 decoding.
2195 --- 2.1.42 2006/12/17
2197 Fixed bug #775: char conversion does not handle Alternative UTF-8
2200 Implemented function yaz_marc_read_line which parses MARC line format
2201 records. There is a wealth of formats out there. So far, this function
2202 reads line records produced by yaz_marc_write_line.
2204 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2205 more generic and easier to remember(!) options: -i format and -o format
2206 which specifies input format and output format respectively - where
2207 format is one of "marc", "marcxml", "line", "marcxchange".
2209 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2210 does not print anything except warnings for records.
2212 For yaz-marcdump, added support for MARC split into files (-s) with a given
2215 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2216 spec, at http://www.loc.gov/standards/sru/record-update/
2217 This has changed the binary layout of the following structs:
2218 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2219 bend_update_rr . Patch by Ko van der Sloot.
2221 Added GFS utility function bend_assoc_is_alive which returns 1 if
2222 association is still alive (client is connected); 0 otherwise (client
2223 closed connection). This allows busy servers to stop working for
2226 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2227 been a separate piece of software. This version of ziffy has been modified
2228 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2230 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2232 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2233 Client code may now interrogate options such as "init_opt_sort" to
2234 find out whether the server claims to support various options.
2236 --- 2.1.40 2006/11/27
2238 Added utilities yaz_{set,get}_esn to set/get element set name from
2241 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2242 of YAZ and has been so since YAZ 2.1.10.
2244 Implemented ZOOM_record_error which returns error information for
2245 record (surrogate diagnostic).
2247 --- 2.1.38 2006/10/31
2249 Updates for SRU Update by Ko van der Sloot:
2250 1. Changed name from "operation" to "action"
2251 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2252 versions in the code, marked as 'backward compatible'.
2253 3. Added diagnostics for SRU Update.
2255 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2257 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2259 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2261 For GFS, fixed problem with SRU diagnostic 'First record position out of
2262 range' being issued for 0 hits.
2264 zoomtst10 part of Windows Build.
2266 --- 2.1.36 2006/10/13
2268 Implemented yaz_filepath_comp which splits a path into file path
2269 components (required by Zebra 2.0.3+).
2271 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2272 BSD inspired license until now so this should not have any real impact on
2273 anybody. See http://www.opensource.org/licenses/bsd-license.php
2275 Fixed bug #687: Missing log lines.
2277 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2280 Fixed bug #689: SRU diagnostics to be added.
2282 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2283 whether a connection is idle (no more work do do).
2285 --- 2.1.34 2006/10/04
2287 Change type of optval from long to int for invocation of setsockopt with
2288 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2290 Added support for specifying the max log file size for the Generic
2291 Frontend Server. The size is given with option -r.
2293 --- 2.1.32 2006/09/21
2295 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2297 --- 2.1.30 2006/09/17
2299 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2302 Fixed bug in Generic Frontend Server that could cause a server to stop
2303 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2305 For the generic frontend server, the maximum record size is used as maximum
2306 size of incoming packages (SRU + Z39.50). The value until was previously
2307 only used in Z39.50 Init negotiation and, later, in a session controlled
2308 sizes of records returned. This is controlled using -k option. It can be
2309 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2311 --- 2.1.28 2006/09/04
2313 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2316 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2318 New option for yaz-marcdump -lpos=value which allows setting a portion
2319 of MARC header to a certain value.
2321 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2323 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2324 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2326 --- 2.1.26 2006/08/15
2328 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2331 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2333 --- 2.1.24 2006/08/08
2335 Fixed MARC ISO2709 encoding routines to deal with character set
2338 Minor changes to GFS logging. Database included in search request log
2341 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2342 cached/multiple records.
2344 Shared libraries are built by default on Unix+configure.
2346 Changed cql2pqf transformation to use a different evaluation order. The
2347 new order is: always, relation, structure, position, truncation, index
2348 and relationModifier. Old order was: always, relation, relationModifier,
2349 structure, index, position, truncation. Note that the the latter ones
2350 override former ones for identical attributes.. The new scheme means that
2351 it is possible to override any existing attribute with a relationModifier.
2352 And also that it is possible to override everything for the index rule
2353 (except the ones listed in relationModifier). No order is perfect but this
2354 one, we believe, covers more real cases.. The "always" should have been
2355 called "default", since the attributes there can be overridden with all
2358 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2359 compilation phase, but also for yaz-config --cflags output. This allows
2360 us to have public headers with Libxml2 stuff in them . It should also,
2361 eventually, make Libxml2 checks redundant in packages using YAZ, such
2364 --- 2.1.22 2006/06/15
2366 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2367 stored in uri, message and details.. Previously diagnostics were stored
2368 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2369 compatibility.. but he's probably the only one affected, so.
2371 Added support for CCL, compiled on the client side, in ZOOM-C. This
2372 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2373 input; the resulting query objects can be used for for searching with
2374 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2376 YAZ' configure searches for OpenSSL by default.
2378 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2379 SL_CTX_use_certificate_file. See
2380 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2381 for more info. Thanks to Ko van der Sloot.
2383 --- 2.1.20 2006/06/02
2385 Bug #600: SRU GET, POST support for yaz-client. Introduced
2386 command 'sru' which selects method SOAP/GET/POST.
2388 Allow missingValueAction to be specified for the sortspec string -
2389 function yaz_sort_spec. By default, the missing value action is null.
2390 Use ! to specify "abort". Use = followed by stringvalue to specify default
2393 Ensured that Present-handler (if defined) is called in GFS before any call to
2394 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2395 searchRetrieve requests.
2397 Documentation for YAZ is now based on the Docbook XML/XSLT using
2398 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2399 is no longer depending on jade/openjade or docbook-to-man scripts.
2400 PDF is no longer part of the distribution - but can optionally be
2401 made using DSSSL/jadetex or FOP.
2403 Added retrieval handling support in Generic Frontend Server to support
2404 conversion between MARC/XML as well as XSLTtransforms. See
2405 etc/yazgfs.xml for an example.
2407 Added Authentication support to Generic Frontend Server in SRU
2408 mode. Authentication using HTTP Basic is supported, as is the use
2409 of 'x-username' and 'x-password' parameters in the request itself.
2411 Added support for a new character set MARC8s identical to MARC8 except
2412 that it converts combined characters to single Unicode characters in the
2413 Latin-1 range (when possible).
2415 --- 2.1.18 2006/04/24
2417 ASN.1 compiler 0.4: generates brief Doxygen file header for
2418 generated .h/.c files.
2420 Utility yaz_iconv now supports conversion to MARC-8.
2422 New facilities for the MARC module. The reading - and writing of
2423 content are separate methods for the yaz_marc_t handle. The following
2424 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2425 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2426 format). Write functions have prefix yaz_marc_write_.. The existing
2427 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2428 available. Removed support for OAI-MARC and simplexml (not the
2429 simplexml from PHP5).
2431 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2432 to be returned for this connection.
2434 --- 2.1.16 2006/03/31
2436 Allow multiple languages and charsets to be specified with
2437 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2438 negcharset iso-8859-1,utf-8
2440 Translation of proximity nodes from CQL into PQF now works.
2442 Moved to automake 1.8, 1.9.
2444 Added function yaz_log_set_handler which allows a log handler to be
2445 installed. This handler will be called for all log messages. Output
2446 to file is also produced; but that can be disabled by passing NULL
2447 fname to yaz_log_init_file.
2449 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2451 For SRW (including GFS), accept application/soap+xml as content-type
2454 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2455 produces NO stylesheet reference even if a default stylesheet is specified
2458 --- 2.1.14 2006/03/14
2460 Updated Windows package to include yazd.dll + yazd.lib for the
2461 Development component.
2463 If the environment variable YAZ_LOG is set, then it is used as a
2464 string indicating the default level of logging to use if not
2465 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2466 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2467 used as before. So, for example, to omit warnings from YAZ logging,
2468 export YAZ_LOG=-warn
2470 cql_transform() now map structure and other attributes before indexes,
2471 so that index-specific structures and other attributes can override
2472 defaults. So now a combination of mapping specifications such as:
2474 index.dc.date = 1=date-modified 4=5
2475 does the right thing.
2477 cql_transform() now also respects the "always" mapping specification,
2478 which establishes an initial set of attributes to be used for all
2479 terms except where overridden by more specific attributes associated
2480 with the index, relation or modifier.
2482 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2483 which mode to use; one of "post", "get" or "soap" (SRW, default).
2485 Fixes for yaz_iconv routines: changed trie-based character set conversions
2486 to use only non-negative values for bit fields due to Sun's C compiler not
2487 supporting negative values.
2489 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2490 sequences where not read correctly. Fix by Rustam Usmanov.
2492 Updated win/makefile to use options, settings which makes things
2493 compile with VS C 2005.
2495 --- 2.1.12 2006/02/01
2497 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2499 In ZOOM socket code, use select instead of poll on MacOSX.
2501 ZOOM-C now support client-side compilation of CQL into RPN that is
2502 sent to the server, enabling CQL to be used against all Z39.50
2503 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2504 ZOOM_query object, and submit it using ZOOM_connection_search().
2505 The CQL-to-RPN translation uses a configuration file, the name of
2506 which must be specified in the Connection's "cqlfile" option.
2508 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2509 function, which takes as its start-term parameter a ZOOM_query object
2510 (which may have had either CQL or RPN set into it).
2513 --- 2.1.10 2005/11/29
2515 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2516 GFS to support this as well. Backend handler, bend_srw_update, does the
2517 update work. Code contributed by Ko van der Sloot.
2519 Allow retrieval of Search Result-1 information in ZOOM by the use of
2520 options that are attached to a result set. ZOOM documentation updated
2523 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2524 UTF-8 conversion. Patch by Raj Patel.
2526 Added option -m to GFS to control formatting of timestamps in log file.
2528 Added 'exit' as synonym for 'quit' in yaz-client
2530 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2531 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2532 for the new members. Patch by Ko van der Sloot.
2534 Added support for SRU POST. It is supported for content-type
2535 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2537 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2538 Instead make the library libyaz.la multi-threaded. Threading as a whole
2539 can still be disabled by configure option --disable-threads. Previosly,
2540 with older GLIBCs there were problems with MT libs under Apache. This
2541 has now been fixed a long time ago.
2543 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2546 CQL module modified to be case insensitive for relations/indexes/operations.
2548 Fixed bug in CQL transform code: incorrect value relationModifieder
2551 Added 'show all' command for yaz-client which retrieves all results
2554 Added new yaz-client, xmles, which takes a (private) OID and
2555 a document to be sent as an extended service request.
2557 Describe new yaz-client commands wait_response and set_auto_wait.
2559 Increase TCP/IP listener backlog from 3 (which I am guessing was
2560 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2561 that the socket will queue as many incoming connections as it's able
2562 to handle ongoing connections. In other words, it will never now
2563 refuse a connection that it would be able to handle merely because
2564 it's not got around to accepting() enough of the pending connections
2565 yet. This is the behaviour anyway under Linux, where the listen()
2566 argument is ignored; but not under BSD and on systems such as
2567 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2568 YAZ-based servers should now be uniform across operating systems in
2571 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2572 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2573 This allows yaz-marcdump to read large MARC batches (>2 GB).
2575 Modified all YAZ source files - except the source which is auto-generated
2576 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2579 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2580 corresponding to the existing *_setl() function. These allow option
2581 values containing arbitrary valuues.
2583 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2584 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2585 except that it returns an indicator of whether or not the sort
2586 criterion was accepted (0 for OK, -1 for invalid).
2588 --- 2.1.8 2005/06/07
2590 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2591 MARC output rather than returning "new" buffer.
2593 yaz-client warns about unknown init options.
2595 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2597 --- 2.1.6 2005/05/24
2599 Added support for SRW sort in Generic Frontend Server. Patch
2600 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2601 sortKeys - or NULL if none is provided.
2603 Fixed bug #307: It was impossible to specify indefinite/no timeout
2604 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2607 Added support for multiple languages and charsets to be specified in
2608 ZOOM. Each charset/language is separated by a blank. If negotiation is
2609 in effect in init-response, Option
2610 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2611 Code based on patch by Vasiliy Osadchuk.
2613 Fixed bug #306: infinite recursion that occurred when calling
2614 yaz_log_level_init as the first call (before other log level or
2617 Fixed bug in scan handling in front end server: if preferred-Position-In-
2618 Response was non-present, a NULL pointer referece was performed.
2620 --- 2.1.4 2005/04/26
2622 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2623 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2624 now defined for all those error codes. So instead of putting 109 in
2625 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2626 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2628 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2631 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2633 Program yaz-client now exits and produces an error message if multiple
2634 Z39.50 servers are specified on the command line (none or one allowed
2637 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2640 --- 2.1.2 2005/03/16
2642 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2644 Fixed bug #272: Preserve spacing for CCL terms.
2646 --- 2.1.0 2005/03/14
2648 Added support for virtual hosts and multiple backend servers for
2649 the YAZ frontend server. The configution is XML based and
2650 support specificition of CQL to RPN mappings and explain information.
2651 See section "Virtual Hosts" in the YAZ manual.
2653 Extended OPAC display utility. OPAC display utility renders
2654 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2655 to supplement yaz_marc_decode_wrbuf.
2657 Fixed a bug in MARC decoder that could caused it to crash for some
2658 invalid MARC records. More diagnostics and warnings where added in
2659 XML output (warnings, etc are stored in comments).
2661 --- 2.0.34 2005/02/08
2663 Fixes for UNIX domain sockets. Bug #261.
2665 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2667 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2668 Added yaz_marc_subfield_str which defines subfield lead string which is
2669 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2670 yaz_marc_endline_str which defines end of fields string used in
2671 YAZ_MARC_LINE format. Default string is newline.
2673 Experimental support for MarcXChange. This format can be produced
2674 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2675 http://www.bs.dk/standards/MarcXchange.xsd
2677 Added yaz-client commands scansize that sets maximum number of
2678 entries to be returned by scan.
2680 --- 2.0.32 2005/01/11
2682 Added support for SRW scan in yaz-client and Generic Frontend Server.
2684 * Added whereInList member to SRW Scan Term.
2686 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2688 Fixed NMEM system to return aligned blocks on the smallest boundaries
2689 that are suitably aligned for all possible types on the particular
2690 architecture YAZ is being built for.
2692 --- 2.0.30 2005/01/04
2694 Fixed numerious warnings that was issued with newer versions of GCC.
2696 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2697 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2700 Make YAZ Generic Frontend Server slightly faster.
2702 Enhance (and reduce) logging for Generic Frontend Server.
2704 Revert YAZ log system so that it flushes every write operation
2705 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2707 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2708 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2709 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2710 will effectively disable old definitions.
2712 --- 2.0.28 2004/11/09
2714 Added yaz_log_time_format which specifies log format using
2717 Added yaz_log_module_level which returns mask for a module. Value
2718 is non-zero mask a if module is enabled; zero if disabled.
2720 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2721 in include/yaz/cql.h.
2723 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2725 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2727 Fixed bug #172: RPM builds does not enable SSL.
2729 Doxyfile.in part of dist. Doxyfile generated by configure.
2731 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2732 are given and the corresponding component does not exist.
2734 Extend CCL documentation in YAZ reference. Describe r=r.
2736 --- 2.0.26 2004/10/01
2738 Fixed MARC->MARCXML conversion to properly deal with
2739 fields, subfields, indicators having non-ASCII characters.
2741 Fixed MARC->MARCXML conversion so that ASCII control characters
2742 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2745 Added YAZ GFS support for conversion from Z39.50 surrogate
2746 diagnostics to SRW surrogate diagnostics.
2748 Bug fix: YAZ GFS did not return schema in explainResponse.
2750 --- 2.0.25 2004/09/30
2752 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2753 now converts recordSchema to elementSetName as well as schema URI.
2755 Fixed bug in COMSTACK that prevented HTTP request packages from being
2758 --- 2.0.24 2004/09/29
2760 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2761 does not require white-space before and after the dash in a range, e.g.
2762 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2765 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2766 due to new GCC removing "redundant" code.
2768 Added yaz-client commands scanpos and scanstep that sets preferred
2769 position and step-size for scan.
2771 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2773 Added CCL utility ccl_qual_buf which parses one or more CCL
2774 spec lines in a buffer.
2776 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2777 of name and value - ignoring empty lines and comments.
2779 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2781 Added odr_get_element_path which returns current element path for an
2782 ODR handle. This utility is useful in error handling or user-defined
2785 Added ODR_PRINT utility odr_set_stream which is is a more generic
2786 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2787 to a write function and pointer to close function. The close function - if
2788 non-NULL - will be called during odr_destroy.
2790 Fixed bug in CCL parser where truncation char was not removed from
2791 right side when truncation=both was in effect.
2793 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2796 --- 2.0.23 2004/08/11
2798 Fix buffer overrun in CQL parser when dealing with proximity (%).
2800 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2801 to UTF-8/UCS conversion is now only based on codetables.xml.
2803 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2805 --- 2.0.22 2004/08/06
2807 Add support for more "commit changes" in ZOOM (uses Extended Services).
2809 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2812 Yet another small fix for configure of SSL.
2814 --- 2.0.21 2004/05/14
2816 Fix SSL libs for configure when --with-openssl=DIR is given.
2818 --- 2.0.20 2004/05/10
2820 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2822 SSL comstack now uses yaz.pem certificate file on server side
2823 by default. Certificate filename can be configured by calling
2824 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2826 Fix bug regarding multiple calls to ZOOM_connection_connect.
2828 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2830 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2831 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2833 ZOOM now allows inspection of X509 peer certificate for verification.
2834 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2836 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2837 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2838 as "modular" but it simplifies things.
2840 Added cs_get_peer_certificate to that returns peer X509 PEM.
2842 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2843 NULL if SSL is unavailable.
2845 Documentation about MARC decoding tools.
2847 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2849 --- 2.0.19 2004/03/30
2851 Rename CHANGELOG to NEWS to follow GNU style packing.
2853 Fix bug with missing initialization of member in init_diagnostics.
2854 This bug affects threaded version of GFS server.
2856 --- 2.0.18 2004/03/20
2858 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2861 Ensure zlib.dll is packed with Windows install.
2863 --- 2.0.17 2004/03/17
2865 Fix encoding of xsd:string to use text instead of CDATA.
2867 Fix endless loop in CQL parser with unbalanced ".
2869 Use a more compact way to store MARC-8 conversion tables.
2871 --- 2.0.16 2004/03/16 Debian only
2873 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2876 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2881 --- 2.0.15 2004/03/01
2883 Another fix for decoding of XML packed records.
2885 --- 2.0.14 2004/02/25
2887 Fixes for Chunked encoding. White space not ignored after length spec.
2889 Update NS and use default NS for SRW diagnostic elements.
2891 --- 2.0.13 2004/02/23
2893 Implement ZOOM_resultset_cache_reset which resets record cache.
2895 Implement ZOOM_resultset_sort which sorts a result set.
2897 Implement chunked HTTP transfer.
2899 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2901 --- 2.0.12 2004/02/16
2903 Added member 'schema' to bend_explain_rr structure so that backend
2904 can specify explain record identifier. Defaults to Zeerex 2.0.
2906 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2908 --- 2.0.11 2004/02/16
2910 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2913 Added init command for yaz-client which sends "extra" init request.
2915 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2916 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2918 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2920 Make ZOOM error code for "invalid query".
2922 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2924 --- 2.0.10 2004/02/05
2926 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2929 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2931 Added option -p <file> to make Generic Frontend Server to write PID file.
2933 Added option -D to put Generic Frontend Server in background on its own.
2935 Make ZOOM C recognize option "password". If unset, "pass" is used
2936 (for backwards compatibility).
2938 Fixed a bug in Generic Frontend Server that could make it crash if a
2939 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2942 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2943 Must be issued before open, in order to be in effect.
2945 --- 2.0.9-6 2004/01/12 Debian/Windows
2947 Make the SRU server more picky WRT unknown params, etc.
2949 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2951 New YAZ client command, options, that sets Z39.50 options.
2953 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2954 options from a string of tokens (one token for each option bit).
2956 Update SRW diagnostic code messages.
2958 --- 2.0.9-5 2004/01/07 Debian/Windows
2960 Handle user defined stylesheet for SRW/SRU.
2962 --- 2.0.9-4 2004/01/06 Debian/Windows
2964 Fix bug in decoding of Content-Length.
2966 --- 2.0.9-3 2004/01/06 Debian/Windows
2968 Fix a bug with decoding of XML packed records.
2970 --- 2.0.9-2 2004/01/05 Debian only
2972 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2974 Fix bug in SRW/SRU diagnostics decoding.
2976 --- 2.0.9 2004/01/05
2978 Fixed bug in Generic Frontend Server which could drop records exceeding
2979 preferred message size. Reported and fixed by Irina Dijour.
2981 Fixed calculation of package size for structured records in Generic
2982 Frontend Server. Reported and fixed by Irina Dijour.
2984 Fixed namespace for SRW/SRU diagnostics.
2986 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2988 --- 2.0.8 2003/12/22
2990 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2991 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2994 CQL changes to reflect recent changes to the specification:
2995 * Documentation talks about context sets instead of index sets.
2996 * Documentation talks about indexes instead of qualifiers.
2997 * The CQL-to-PQF transformer's configuration file now uses
2998 "index.set.name = <attributes>" instead of the old form
2999 "qualifier.set.name = <attributes>". (Both forms are still
3000 understood but the latter is deprecated.)
3001 * CQL terms with no explicit index specified are now interpreted as
3002 cql.serverChoice instead of srw.serverChoice (which of course
3003 behaves exactly the same.)
3005 --- 2.0.7 2003/12/16
3007 MARC conversion can now generate ISO2709 output in another
3008 character set. yaz-marcdump uses this facility if you invoke it
3011 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
3012 functions from there can be used from C++.
3014 --- 2.0.6 2003/12/04
3016 Frontend server now transfers memory from decoded packages to stream
3019 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
3020 references to show up.
3022 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
3023 the ZOOM Abstract API. The older names for the same options are still
3024 also supported for the benefit of old applications.
3026 ZOOM-C supports "implementationId" and "implementationVersion" options
3027 to go along with "implementationName". These allow the user code to
3028 specify identification strings to be sent to servers.
3029 Add OID for the new ExtLite attribute set.
3031 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
3032 as requested/supplid by Ere Maijala <ere@atp.fi>
3034 For generic frontend server, reverse the order of
3035 "toolkit-supplied / application-supplied" strings sent as implementationId,
3036 Name and Version. Also, remove the spaces around the slash. This brings
3037 the GFS in line with the behaviour of ZOOM-C on the client side.
3039 Add function ZOOM_scanset_display_term.
3041 yaz-client shows scan displayTerm if present.
3043 Utility yaz-iconv is now installed by default along with the man page
3046 Extend configure check for OpenSSL to use pkg-config where available (such
3049 Incorporate patch by Morten Bogeskov which allows a Unix file socket
3050 server to specify uid/gid/mask for socket using the format
3051 unix:[user=uid,][group=gid,][umask=mask,]file=path
3052 If file= is omitted the existing format is assumed, e.g.
3054 in which case the mask is 0666 (rw for everybody).
3056 Major restructure of YAZ source. All source in libyaz is in src directory.
3057 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
3058 util (utility programs such as ASN.1 compiler, yaz-marcdump).
3060 Added man page for utility yaz-marcdump (used to be called marcdump).
3061 yaz-marcdump is installed by 'make install'.
3063 Fixed a memory leak in Generic Frontend Server that occurred when decoding
3064 of incoming package failed.
3066 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
3068 Change prototype of odr_perror: add const to message string.
3070 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
3072 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
3073 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3074 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3075 DNS lookup. There should not be any compatibility problems with this
3076 assuming that blocking=1 or 0 is used.
3078 Fix bad reference in UNIX comstack in function cs_addrstr.
3080 Fix for compilation on AIX.
3082 The generic front-end server (server/seshigh.c) now supports returning
3083 Init diagnostics to the client in User-information-field, in
3084 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3087 --- 2.0.4 2003/09/04
3089 Allow any CQL relation (not just all,any,exact,scr).
3091 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3092 that features the same UI.
3094 Implemented command update0 in YAZ client which is equivalent to
3095 update but uses old of Ext Update ASN.1.
3097 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3098 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3099 Previously no OID was used for this info.
3101 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3102 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3103 returns 'malformed search term' otherwise.
3105 SortResponse member resultCount now set to NULL in sort handler of
3108 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3111 Add three new utility functions for translating OIDs between various
3112 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3113 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3114 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3115 char *oid_to_dotstring(const int *oid, char *oidbuf);
3116 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3118 Reverted modifications for ES Update definition for z_IU0Update
3119 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3120 is back to YAZ 2.0.2.
3122 String value attributes for CCL parser.
3124 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3125 which their FirstSearch server returns in Init responses, sometimes
3126 carrying useful diagnostic information when Init fails. This has the
3127 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3128 "z39.50/oclcui.asn", where its definition is somewhat different from
3129 what OCLC document on their web-site, as required to interoperate with
3132 Support for anonymous authentication in yaz-client. Use the command
3135 * Fix the OID of the Index Data-local "admin" Extended Service from
3136 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3137 the 1000, which indicates a locally-defined OID, was a mistake.
3139 --- 2.0.3 2003/06/20
3141 Fix CCL directive @case handling so that it affects string match for
3142 both CCL keywords and qualifiers.
3144 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3145 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3146 Decoder has been updated with ASN.1 changes as listed in
3147 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3148 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3149 z_IUUpdate, remains unchanged.
3151 ZOOM_record_get may now return a record in a specific character set.
3152 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3153 "from" is the character set of record as returned by target. "to" is
3154 the character set to be returned. If omitted, "to" is UTF-8.
3156 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3158 New ODR utility, odr_getelement, which returns name of element for
3159 which encoding/decoding failed.
3161 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3162 in cases where a required element was omitted.
3164 Bug fix: some MARC8 sequences were not converted.
3166 New ZOOM option "step" which specifies number of records to be
3167 retrieved in one chunk. Used in conjunction with "start" and "count".
3169 SRW support for yaz-client. Use scheme http: to use it, e.g.
3172 yaz-client no longer does (un)intelligent character set conversions
3173 by default. Can be enabled with charset and marc_charset commands.
3175 xmalloc trace fix for 64-bit systems such as DEC alpha.
3177 Solaris 2.6 compile fix.
3179 New function, cql_strerror() translates SRW error codes, as returned
3180 by cql_transform_error(), into human-readable English strings. Used
3181 in yaz-client diagnostics when appropriate.
3183 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3184 converts it into a type-1 query which is sent to the server. This
3185 makes CQL available for use with all Z-servers, as opposed to the tiny
3186 minority that can handle CQL queries themselves.
3188 --- 2.0.2 2003/04/28
3190 New Debian package layout similar to the Redhat Package layout.
3192 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3193 and search result respectively.
3195 --- 2.0.1 2003/04/25
3197 Redhat package is now several packages: libyaz (runtime libraries),
3198 libyaz-devel (development and documentation, and yaz (utility programs).
3199 Package spec file by Morten Bogeskov.
3201 New member 'schema' in struct bend_fetch_rr which the name of requested
3202 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3203 handler MAY set this to reflect the schema of the returned record.
3205 New member 'display_term' in struct scan_entry. GFS now sets member entries
3206 and allocates scan entries to be filled by user scan handler. In previous
3207 version, entries member was allocated by the scan handler. That still works,
3208 but the GFS will ignore member display_term - assuming it was NOT set by
3209 the handler. The fact that the GFS now allocates the entries both allows
3210 for new members and makes a scan handler easier to write.
3212 Fix CQL lex buffer overflow.
3214 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3215 SRU default recordPacking is string.
3217 SRU protocol support for frontend server.
3219 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3221 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3223 Added scan for the ZOOM shell (zoomsh).
3227 * String Identifers for Schemas (Amendment 5).
3228 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3229 Old definition for schema
3230 Odr_oid *schema; /* OPT */
3235 Z_InternationalString *uri;
3236 #define Z_Schema_oid 1
3237 #define Z_Schema_uri 2
3240 * resultCount parameter to Sort Response (Amendment 1).
3241 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3243 Support for SRW 1.0 over HTTP. This is an optional feature and
3244 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3247 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3248 on the same port. SRW SearchRetrieveRequests are mapped
3249 to bend_init,bend_search,bend_fetch,bend_close.
3251 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3253 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3254 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3256 ZOOM connections are SRW based if schem http is used for hostname
3257 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3258 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3260 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3261 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3262 distance=n, order=true/false, relation=le, prox unit=word. If
3263 n is omitted, distance 1 is used.
3265 Fixed problem with C compiler include path in wrong order.
3267 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3268 on Solaris. Patch from Ko van der Sloot.
3270 New MARC decode API. All new functions operate on a yaz_marc_t
3271 handle. The most important new functions are: yaz_marc_create,
3272 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3273 decode and destroy respectively. Decoder can produce formats
3274 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3275 include/yaz/marcdisp.h.
3277 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3278 to UTF-8, UCS-32, wchar_t or Latin-1.
3280 * Prototypes for yaz_iconv_-functions moved to separate header
3281 include/yaz/yaz-iconv.h.
3283 Make a few private functions 'static' in unix.c. This prevents
3284 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3286 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3287 are set when Init Response is received.
3289 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3290 but returns diagnostic set as well.
3292 New function yaz_strerror which is a portable wrapper for
3293 strerror/strerror_r/GetLastMessage.
3295 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3296 is returned for MARC. If type is "oai", then OAI MARC is returned.
3298 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3301 --- 1.9.2 2002/11/26
3303 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3305 Fix bad race conditions on SIGTERM and terminate gracefully in
3308 Move retrieval (data1) module to Zebra since nobody seems to be
3311 Add GRS-1 render for ZOOM using same format as yaz-client.
3313 --- 1.9.1 2002/10/05
3315 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3317 Fix broken ESpec handling in data1 module.
3319 SGML reader parses comments and makes them part of the data1 tree.
3321 Added several type casts so that YAZ compiles as C++ code.
3323 ZOOM didn't handle PDU encoding failures properly.
3325 Added more Bib-1 diagnostics (approved extensions).
3327 GNU configure: better check for iconv.
3329 More portable use of accept, getpeername. Check for socklen_t. Use
3330 int/size_t if socklen_t is not defined.
3334 PQF parser rejects bad queries - including those with extra
3335 characters in them. PQF parser used to silently ignore that.
3336 Cleaner API for PQF added, which allows you to get detailed
3337 error information for bad queries (see yaz/pquery.h).
3339 Fixed bug in ZOOM_record_get for type "database".
3341 Implemented mini iconv library supporting conversions between
3342 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3344 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3346 --- 1.8.9 2002/08/20
3348 Fixed ZOOM C record cache so that preferredRecordSyntax and
3349 elementSetName is used to check for already fetched records.
3351 --- 1.8.8 2002/08/02
3353 Added three members in bend_initrequest structure to facilitate
3354 character set negotiation.
3356 Fixed a bug in frontend server that could cause indefinite
3357 loops under rare conditions.
3359 Revised character set utilities (charneg.h) so that encoding
3360 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3362 For PQF, directive @term <type> sets term type for Scan/Search.
3363 Here <type> is general, string, numeric, null. The term type
3364 is inherited - just like @attr.
3366 New call odr_set_charset that sets character set conversion for
3367 international-strings on a ODR stream. Prototype is:
3368 int odr_set_charset(ODR o, const char *to, const char *from);
3369 The InternationalString is still represented as C string in YAZ
3370 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3371 won't). On the protocol level, you can use any encoding.
3373 Support for UNIX sockets in ZOOM.
3375 Solaris recv sometimes returns errno == ENOENT. It is treated as
3376 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3378 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3379 both client and server. Code by Morten Bogeskov.
3381 --- 1.8.7 2002/05/22
3383 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3384 that they can be used directly from Visual Basic. You must recompile
3385 your windows APP if you're using ZOOM.
3387 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3388 Commands "lang" and "charset" sets language and character set respectively.
3389 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3390 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3392 Attributes from multiple CCL fields may be OR'ed rather than merged
3393 using directive "@field or". Fields are still merged by default -
3394 equivalent to "@field merge".
3396 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3399 Fixed bug in zget for parameter ExtendedServicesResponse.
3403 --- 1.8.6 2002/03/25
3405 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3407 Client displays USR.1:SearchResult-1 (hits per term).
3409 Additional Search Info for search in Generic Frontend Server.
3411 Fixed CCL parsing of "field=s".
3413 WIN32 installer - using the excellent NSIS software from nullsoft.
3415 Fixed CCL parsing of "field = - <number>".
3417 Added function yaz_marc_decode that decodes MARC for line mode
3418 display or XML (similar to that used by JZKit).
3420 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3421 Z39.50. But ISO/ILL was, however.
3423 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3424 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3426 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3427 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3429 --- 1.8.5 2002/02/03
3431 New YAZ client features: Command completion and new commands:
3432 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3433 Code provided by Jacob Poulsen.
3435 New call oid_trav, that visits all registered OIDs via callback.
3437 Function ZOOM_record_get now returns const char pointer rather than
3438 void pointer. It saves a lot of type casts.
3440 For YAZ client, command "auth" now allows you to set authentication
3441 in IdPass style. It is enabled when three tokens are given - order
3442 is user, group and password.
3444 Fix memory leaks in MARC record handling for ZOOM.
3446 New option for YAZ client, -k <kilobytes> that sets
3447 maximum record size. Similar to -k option for generic frontend
3448 server and yaz-ztest.
3450 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3452 Prefix query parser reports "fail" when bad attribute set is given.
3454 Fix in MARC decoder. Proximity logging. Fix for attribute set
3455 in scan handler for server. Patches by Shigeru Ishida.
3457 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3460 Configure option --with-openssl=<dir> now works when a directory is
3461 specified. Patch provided by Morten Bogeskov.
3463 New option for YAZ client, -u <auth>, that sets authentication.
3465 ZOOM fix: error information was sometimes "missing", since error
3466 was cleared/reset too when it shouldn't.
3468 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3470 --- 1.8.4 2002/01/04
3472 Scan for ZOOM API. New object ZOOM_scanset. New functions
3473 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3474 ZOOM_scanset_destroy.
3476 New ZOOM function, ZOOM_connection_last_event, that returns type
3477 of last event (such as "receive data", "send data", "apdu received",
3480 New ZOOM option, schema, that specifies schema for retrieval.
3482 New CCL feature. Qualifiers can be aliases for one or more
3483 other qualifiers (if more than one is given, OR is used).
3485 ZOOM uses named result sets if target supports it.
3487 Two new YAZ client commands: . (dot, which sources a script of YAZ
3488 client commands), and ! (to execute shell command.). Implemented
3491 Working on Debian packages.
3493 --- 1.8.3 2001/11/19
3495 YAZ client enables named result sets only if target supports it.
3497 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3499 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3500 with key="host" to get same result.
3502 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3503 Function Z3950_resultset_record(s) returns references to records
3504 "owned" by resultset. To become owner use Z3950_record_clone.
3506 Function z_ext_record handles Extended Services. Thanks to
3509 --- 1.8.2 2001/11/12
3511 CCL Parser fix: ignore token comma when dealing with and-lists.
3513 Documentation updates for COMSTACK.
3515 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3516 Changed prototype Z3950_records. For some functions, int parameters
3517 were changed to size_t.
3519 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3522 New MARC decode/display function, marc_display_exl, which properly rejects
3523 non-ISO2709 records. YAZ client uses it.
3525 --- 1.8.1 2001/10/29
3527 Fix bug: local attribute set wasn't set correctly in PQF strings.
3531 * Old Z39.50 codecs no longer supported.
3533 Added ZOOM C binding. See http://zoom.z3950.org/
3535 Renamed states for COMSTACKs to avoid confusion with events.
3537 Implemented cs_look and proper cs_rcvconnect.
3539 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3541 Configure detects POSIX threads on OpenBSD.
3543 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3544 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3546 When error is returned from present handler, non-surrogate diagnostic
3547 is returned in present response (and fetch handler is no longer called).
3549 * Minor adjustments to pquery parser (PQF). Token characters may be
3550 escaped by using backslash (C-style).
3552 PQF parser allows string attribute values to be specified. For @attr,
3553 non-numeric characters after the equal-sign are treated as strings
3554 (e.g. @attr 9=title).
3556 CCL trunction character may be defined (@truncation in file)
3558 * function zget_ExtendedServicesRequest sets waitAction to
3559 waitIfPossible (was wait).
3561 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3564 CCL operator names may be set in field definition files (CCL_bibset).
3565 See ccl/bib1 for an example.
3567 Fixes in ASN.1 compiler for C++ compatibility.
3569 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3570 and "op_or" to avoid conflict with C++.
3572 Fixed problem with GNU readline detection on Redhat 7.0.
3574 Added step-size for Scan backend handler.
3576 Fixed bug that made the frontend server crash when no attribute
3577 set was specified for scan.
3579 Front-end server automatically switches to original working directory
3580 when installed as an NT service. Previously -w had to be specified to
3583 Added extended attributes for retrieval module (data1), so that data1
3584 records carry d1_readXML/SGML attributes. d1_read also supports
3585 null-data rules ( <tag/>)
3587 On UNIX when POSIX threads are available, a separate library libyazthread
3588 is created. Programmers should link with that library and the yaz library
3589 when using threads. The reason for the split was that some applications
3590 on Linux, such as Apache, doesn't work well when using shared objects that
3593 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3594 (or any frontend server) in SSL mode by specifying ssl: followed by
3595 address. Only tested on UNIX.
3597 Added feature for CCL module. Virtual structure s=al or s=ol generates
3598 and-list and or-list respectively instead of phrase search.
3602 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3603 log_mask_str. This was done to avoid name conflicts with other libraries
3604 (such as other PHP extensions).
3606 Added raw OID member for preferred record syntax (request_format_raw)
3607 and returned record syntax (output_format_raw) for backend fetch method.
3609 Config file yaz-config now accepts options so that it returns specific
3610 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3612 Shared library support for UNIX using GNU libtool.
3614 * Modified backend interface. Request/Response struct's replaced by
3615 one read/write C struct. For example bend_fetchrequest and
3616 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3617 Every handler - even search has to be registered in bend_init
3618 handler. This means that the YAZ library no longer refers to
3619 external functions and it makes it possible to make the whole
3620 thing a single DLL/SO.
3622 Added Segment handler for backend server.
3624 Added Zmbol/Zebra administrative functions to YAZ client.
3626 Threaded frontend server on UNIX (when POSIX Threads are available).
3627 Starting the server with option -T enables multi-threading.
3631 Added configure option --enable-comp/disable-comp to control use
3632 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3633 located in sub directory asn.
3635 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3636 in ${exec_prefix}/bin along with the other programs yaz-client and
3639 GNU automake used to maintain makefiles.
3641 Added several OID's.
3643 Changed retrieval module so that we can load records with no abstract
3644 syntax defined. Tagpaths in these records are fully composed of string
3647 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3651 On UNIX, the generated makefile now supports a proper 'make install'.
3652 The prefix can be set via GNU configure to set the install location
3653 (default is /usr/local).
3655 * YAZ programs client and ztest were renamed to yaz-client and
3656 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3657 locations, such as /usr/bin,/usr/local/bin,etc.
3659 * YAZ Header files were moved from include to include/yaz. YAZ Header
3660 files are referred to as include <yaz/log.h> rather than <log.h>.
3661 The YAZ include path (-I ..) is therefore the same as before. Programmers
3662 should update their #include statements or use -Ipath/include/yaz
3663 instead. The main motivation for doing this change is that YAZ header files
3664 can be installed in "standard" locations /usr/include,/usr/local/include
3665 without introducing conflicts, since ALL YAZ header files are stored
3666 in subdirectory yaz (under /usr/include for example).
3668 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3669 rather than project/workspace files. We switched because project files
3670 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3673 Changed name of logging function, logf, to yaz_log, to prevent name
3674 clash with some math-log functions. The YAZ header log.h defines logf
3675 to yaz_log (#define) so there should be no incompatibilities by this
3678 Added bend_start/bend_stop handlers for server. These handler are
3679 called on start/stop of server. For windows they are called whenever
3680 a service is started/stopped.
3682 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3683 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3684 in util/yc.tcl. The auto-generated C code structures are, in a few
3685 cases, incompatible with the old decoders. There are differences in the
3686 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3687 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3688 The preprocessor variable ASN_COMPILED is defined when the compiled
3689 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3690 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3691 wish to use the old encoders/decoders you can specify --disable-yc
3694 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3695 version so that it supports both new - and old version of DB Update
3697 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3698 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3699 change. The name parameter can be set to 0 in which no name is specified
3700 for the construction. The macros odr_implicit and odr_explicit sets name
3701 parameter to zero for the construction involved. New macros
3702 odr_implicit_tag and odr_explicit_tag are similar to the others,
3703 except that a name parameter is added. For programmers' that don't use
3704 ODR they probably only need to change the call to z_APDU and z_External.
3706 Added access control facility by interfacing the TCP wrapper library.
3707 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3708 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3709 name of the daemon and enables the access control as specified in
3710 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3712 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3713 den Dool <H.M.vdnDool@kub.nl>.
3715 Added reference ID parameter to most functions in server API - refer
3716 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3718 Changed name of ccl library to libccl.a (was ccl.a).
3720 Fixed bug in decoder for Explain (Category TargetInfo).
3722 Added support for GNU readline in client. Thanks to Jacob Poulsen
3723 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3725 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3726 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3727 IMPLEMENTATION! This change was made to the development version before
3728 the ZIG decided to retract the amendment. If any users MUST be
3729 compatible with the original Update definition, PLEASE CONTACT US, and
3730 we will include a separate definition corresponding to the old Update
3731 ES. Note that because of the change to the ASN.1 of the
3732 TaskPackageRecordStructure we cannot define a single structure that
3733 will support both versions.
3735 * Added const modifier to buffer parameter for some ODR/BER encoding
3736 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3737 completeWAIS, odr_dumpBER.
3739 Fixed bug in client.c which caused a crash when a scanResponse didn't
3740 contain positionOfTerm.
3742 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3743 * will cause an error in a client if a non-YAZ target sends both a
3744 * list of Scan entries and non-surrogate diagnostics.
3746 Retrieval module enhancements. Tag sets may be typed in the reference
3747 to it. From the .abs-file the "tagset" directive takes a third optional
3748 integer type for the tag set referenced. From a .tag-file the "include"
3749 directive takes a third optional type as well. The old "type" directive
3750 in the tag set itself is still recognized but acts as the default type
3753 Backend interface change. Individual Scan terms returned from bend_scan
3754 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3755 in include/backend.h.
3757 Retrieval module enhancements. Multiple tag sets and attribute sets may
3758 be specified in abstract syntax specs. Revised the error/warning for
3759 logging messages reported by the retrieval module when reading the
3762 Object Identifier system (oid_..) changed. The API is backwards
3763 compatible but the oid-routines now allocates new OID's when needed.
3764 Raw OID's may be specified in oid_getvalbyname.
3766 YAZ now uses GNU configure to generate Makefile(s).
3768 * Minor changes in some of the member names of DeleteResultSetRequest and
3769 DeleteResultSetResponse. See include/proto.h.
3771 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3772 and added member 'languages' in TargetInfo (which was missing).
3774 Changed the way attribute sets are handled in the retrieval
3775 module. These are now cached, just like the abstract syntaxes
3778 Changed YAZ so that it links with compiled ASN.1.
3780 Added Explain-schema definitions and mapping routines. The following
3781 Explain categories have been implemented: AttributeDetails,
3782 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3784 Fixed minor bug in Windows version of Server Library.
3786 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3788 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3790 Added EXTERNAL: UNIverse Resource Report (non-standard).
3792 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3793 ENUMERATED and SET OF.
3795 * Added 'const' to some of the char pointer arguments for the
3796 functions, data1_read_node, data1_getelementbytagname,
3797 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3800 Fixed bug in data1_insert_taggeddata - the last_child member of
3801 parent wasn't initialised.
3803 * Changed data1_read_record and data1_read_node so that the supplied
3804 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3805 doesn't refer to any parts of the "SGML"-buffer.
3807 Fixed bug in server library (Windows version of statserv_remove).
3809 * Changed code so that it compiles as C++. The type definition
3810 of Odr_fun which is a member of Odr_arm was changed. The result is,
3811 that an explicit typecast is needed for the fun pointer when
3812 using Odr_arm - as in:
3813 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3815 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3817 Implemented the new structured date and time definition as approved
3818 by the ZIG. Added schemaId element to the specificTag in Espec-1
3819 (also approved at the last ZIG). Thanks to RVDM.
3821 Added some Object identifiers (RVDM).
3823 Changed the Update Extended Service (RVDM).
3825 Added command "refid" to client which specifies referenceId for
3826 the following requests.
3828 Implemented extended service handling for server. See ztest.c
3829 for an example as well as backend.h. New handlers are registerd
3830 in the Init handler.
3832 * Changed interface for sort in server.
3834 Added new members to statserv_options_block. It allows a server
3835 to read options from another source than just the command line. Thanks
3836 to Charles Woodfield.
3838 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3839 renamed to zboolean. Some C++ compilers complained about the name.
3841 Minor changes to gils.abs. Added index 's' (sort) on title
3842 and date/time-last-modified.
3844 --- 1.4pl2 1998/1/30
3846 Fixed bug in server library regarding inetd mode (-i). This bug
3847 was introduced by release 1.4.
3849 --- 1.4pl1 1998/1/29
3851 Added sort facility in client and backend server interface.
3853 Fixed problem with dependencies in Makefile(s).
3855 Fixed bugs for encoders/decoders of extended services and
3858 Implemented sub-tree feature for schemas. Sub-trees are
3859 referenced in *.abs-files. See explain.abs for an example
3860 of the use of this feature.
3862 Modified bib1.att; local attributes for ANY didn't include
3863 ANY itself (only affects use of the retrieval module).
3865 Fixed bug in plain SGML reader in function data1_read_node:
3866 tags with prefix "var" was incorrectly interpreted as variants.
3868 Added feature "sub-schemas" to enable references to - and definitions
3869 of - group of elements.
3871 * Removed member parent from type data1_element (in data1.h).
3873 Implemented function odr_nullval() that returns the value of
3876 * Removed member num_children from data1_node (in data1.h).
3878 Made NT service interface part of the server library. The
3879 function statserv_main uses the NT service when required and
3880 calls the statserv_start / statserv_close routines.
3882 Routine zget_SearchRequest and zget_PresentRequest fills
3883 resultSetName/Id member with "default" instead of "Default".
3885 Fixed memory leak in server. Request queue member wasn't freed.
3887 Fixed nmem_exit so that memory is freed.
3891 Revised the CCL parser utility to be thread safe.
3893 Added function, oid_ent_to_oid, to replace the function
3894 oid_getoidbyent, which is not thread safe.
3896 * Added nmem_init and nmem_exit to initialize and release
3897 NMEM resources. Function nmem_init should be called once in the
3898 initial thread before NMEM/ODR is used. statserv.c and client.c
3899 have been changed accordingly. The change was necessary to make
3900 NMEM thread safe. The NMEM memory pool is shared amongst threads
3901 in a process. Unix-based applications will still work fine without
3904 Added NT Services interface for the the Z39.50 (statserv) Server.
3905 Refer to the ztest.c source on the usage.
3907 Windows 95/NT port using MSVC5.0. Project files are included in the
3910 * Defined new 'global' handle for the retrieval (data1) system. The
3911 new handled, data1_handle, describes the state of the data1 system.
3912 This handle is passed as first argument to virtually all
3913 data1 related routines. The functions data1_create and data1_destroy
3914 creates and destroys a data1 handle respectively.
3916 Added ODR encode stream member to all backend request structures
3917 init, search, scan etc. This stream should be used to allocate all
3918 memory used for the response when thread safe operation is needed.
3920 Changed the comstack utility, cs_addstr, to be thread safe. The
3921 returned hostname string returned by the function is now part the
3924 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3925 function. The cs_straddr takes a COMSTACK handle as argument, so this
3926 function must be used after cs_create and before bind/connect.
3927 This function is thread safe.
3929 Moved test server to 'ztest' directory - generic server code still
3930 in 'server' directory.
3932 Made prefix query (pquery.c) utility thread safe.
3934 Added new function modifier YAZ_EXPORT to 'export' public DLL
3935 functions when using windows (see include/yconfig.h).
3937 Added definitions to the OID database (util/oid.c) (RVDM).
3939 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3941 Added call to ccl_rpn_delete in client program.
3943 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3944 release of RPN structure.
3946 Added support for C++, headers uses extern "C" for public definitions.
3947 With input from RVDM.
3949 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3950 Thanks to Ronald van der Meer (RVDM).
3952 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3954 Added support for private extensions to the OID database
3955 (oid_setprivateoids()). Thanks to RVDM.
3957 Added optional, physical ANY (key replication)
3959 Fixed null-reference problem in GRS-1 output filter.
3961 Proximity operator added to Prefix Query Format (PQF).
3963 In test client command "base" accepts multiple databases.
3965 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3969 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3971 Smallish bug-fixes in the new encoders/decoders (explain).
3973 Bug fixed in DeleteRequest.
3975 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3977 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3979 Added SOIF syntax (using private OID for now) to retrieval module and client.
3981 Added Update extended service.
3983 Added SearchResult-1 additional info structure.
3985 Added optional CCL (ISO8777) interpreter as separate module. Available
3988 --- 1.2 1996/6/10 (1st anniversary release)
3990 Added Summary record syntax. Lightly tested.
3992 Added OPAC record syntax. Untested.
3994 Added ResourceReport service encoders/decoders. Untested.
3996 Fixed bug in z_Unit - wrong tagging on unitSystem.
3998 Fixed bug in the DiagRecs decoder.
4000 Added options for max PDU size and session timeout to frontend-server.
4002 Added documentation of query-language parsers and other supporting utilities.
4004 [frontend-server] Added Attribute set to the bend_scanrequest API.
4006 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
4007 surrogate diagnostics were generated.
4009 [retrieval] Allow multiple local values for attribute.
4011 [retrieval] Allow multiple attributes per element in .abs files. index type.
4013 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
4015 --- 1.1pl2 1996/4/10
4017 Minor changes, mostly specific to Zebra's requirements (retrieval)
4021 Repaired bug in frontend server when running multiple listening
4022 endpoints in dynamic mode.
4024 z_External() now won't break if a known, ASN.1 value comes encapsulated
4025 in an octet-string. The value will pass through unmodified in an Odr_oct.
4027 Added a bit of code to the demo client to decode & display
4028 ASN.1-structured records represented in the octet-aligned branch of
4029 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
4031 Added z_ext_getentbyref() to the ASN module. Doc updated.
4033 * Completed the SCAN definition in the ASN module. This may break SCAN
4034 code based on older YAZ-versions at compile-time. The fix is easy -
4037 * Added 'displayTerm' and OtherInformation to the TermInfo structure
4038 under the SCAN definition. Remember to initialize this, server-people.
4040 Comstack should now support the WAIS protocol in TCP/IP mode. Note
4041 that this does not extend to ODR and ASN.
4043 Comstack allows insertion of established socket (primarily for
4044 inetd-operation of servers). Doc updated.
4046 Front-end server can now start from the inetd in TCP mode. Doc
4049 --- 1.0pl4 1996/1/24
4053 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
4054 the rank and record number.
4056 Adjustments to the frontend server.
4058 Fixed diagnostic BER dumper. It ignored the file argument.
4062 Various changes to retrieval module.
4064 Changed the union discriminators of the protocol files from enums to
4065 ints paired with #defines.
4067 *Changed oident.class to oident.oclass to avoid a reserved word in C++
4070 *Changed operator in the RPN structure to 'roperator', again to avoid a
4073 Fixed problems in Explain decoders/encoders.
4075 --- 1.0pl2 1995/12/6
4077 Memory bug in log module fixed.
4079 --- 1.0pl1 1995/12/5
4081 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4083 Bug in Explain DatabaseInfo module fixed.
4085 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4089 The shift to v1.0 signals that we now consider the *core* functionality
4090 of YAZ reasonably stable (the core being more or less equivalent to
4091 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4092 tested (Explain not at all - though that will happen soonish).
4094 Minor changes to code to support Windows port.
4096 Various minor changes after we're getting to use GRS-1 & co. more.
4098 Added Espec-1 format.
4100 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4101 of the protocol and it cannot be selected when encoding (maps into 'string'
4102 when decoding). Needed to talk to some servers.
4104 Demo client can request simple element set names.
4106 Added Diagnostic Format encoders/decoders.
4108 Added simple Close handling to frontend server (no hooks for resource
4109 reporting yet), and demonstration client.
4111 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4113 --- 1.0b3 1995/08/24
4115 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4116 handled incorrectly when records were requested in the searchResponse. This
4117 will only affect you if you use the frontend-server.
4119 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4120 Test-client will ask for and print GRS1. Ztest will return dummy records
4123 Added Explain encoders/decoders to the service-level API. Untested.
4125 Added Extended Services: Item Order encoders and decoders to the Service-
4126 level API. Untested. We could use a recent copy of the pertinent bits
4127 of the ILL protocol to add those bits.
4129 Added diagnostic format 1 encoders/decoders to the service-level API.
4132 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4133 odr_cons.c, which causes a more correct output.
4135 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4136 was always set to 0 when no records were requested in the searchRequest.
4138 * Added better external-handling. This shouldn't harm old code that
4139 *encodes* externals. It can break code that looks for a
4140 'single-ASN1-type' representation, since those types that are known
4141 are now decoded immediately. Look at the SUTRS sample code in
4142 seshigh.c and client.c. Documentation updated.
4144 Handling of structured records in bend_fetchresponse. Length -1 marks
4145 structured record, type is deduced from format field.
4147 --- 1.0b2 1995/06/27
4148 Fairly quick maintenance release to add SUTRS support.
4150 Fixed handling of SUTRS records in the demonstration client.
4152 * Added format field to the bend_fetchrequest and bend_fetchresponce
4153 structures of the backend API (frontend server). When the record is
4154 returned, the value of the format field is mapped to an OID. The
4155 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4156 of the record. The special value VAL_NONE in the bend_request means
4157 that no specific format was requested by the client. Documentation
4158 updated accordingly. Test server (ztest) will return a fixed dummy
4159 SUTRS record if your client requests SUTRS.
4161 Documentation updated accordingly.
4163 You can now set external libraries and RANLIB support in the top-level
4167 First public release.
