23 Document itemorder-setname and list all ILL options
27 Extend get_org_info (snippets) to return original string YAZ-836
28 Two new functions have appeared: icu_chain_get_org_info2 and
29 icu_iter_get_org_info2 with a 4th parameter being a pointer
30 to the original string.
32 Fix tcpip.c compilation failure on VC9 YAZ-835
34 Fix icu_iter_get_norm returns invalid size for some input YAZ-834
35 The icu_iter_get_org_info returns information based on string
36 as it appears on tokenize step.

46 Fix SEGV yaz-client for HTTP decoding error YAZ-829
48 Fix buffer overflow in cmd_elements in yaz-client YAZ-828
52 Fix test_sru.sh fails in pazpar2 YAZ-826
53 Unfortunately a regression occurred with YAZ 5.10.0 that would make
54 Pazpar2 fail for HTTP connections.
58 Use CONNECT for SSL backends and for Z39.50 thru HTTP proxy YAZ-825
59 Introduce cs_create_host2 which returns if connection should be
60 proxy aware (HTTP:absoluteUri or Z39.50 proxy:vhost in init).. For CONNECT,
61 the connection is NOT proxy aware (no absoluteUri and no Z39.50 vhost).
63 Fix http proxy fails with yaz-client YAZ-824

83 record_conv: selection by X-Path YAZ-811
84 That's a new step in record conversion system (<select path=".."/>)
86 Document record render parameters for ZOOM - including base64
90 Fix application/x-www-form-urlencoded + empty YAZ-810
91 A SEGV occurred if Content-Type was "application/x-www-form-urlencoded"
92 and empty content was supplied.
94 Fix yaz-iconv man page for typos and incorrect example. YAZ-809
96 Fail hard if Bison is not found and is needed YAZ-808
100 Enable YAZ backtrace for programs YAZ-802
102 Update NMAKE makefile to use Visual Studio 2013 along with ICU 54.1,
103 Libxml2 2.9.2, Libxslt 1.1.28.
105 Fix daemon: parent process stops before child YAZ-806
106 Try to fix the situation where parent process stops before
107 child has acknowledged it .. SIGUSR2 back!
109 daemon: log message when keepalive stops.
113 Fix yaz-marcdump segfault YAZ-801. Problem in YAZ 5.6.0/5.7.0 and
114 would make yaz-marcdump crash when from-character set was issued.
118 Dump backtrace in case of SIGABRT, SIGSEGV YAZ-787
119 New function yaz_enable_panic_backtrace which enables backtrace
120 handler for current process. The handler will call backtrace always,
121 then gdb to provide as much detail as possible.
125 When marc-8 charset is specified when decoding MARC records, yaz-marcdump
126 and ZOOM record render will inspect leader 9 and switch to UTF-8
127 (Unicode) if that holds 'a'. This changes behavior, but is considered
128 safe because only MARC21 with leader 9='a' are Unicode. YAZ-800
130 Fix cs_put may reconnect if send fails. YAZ-798
134 Fix cannot build YAZ on jessie : libgnutls-dev is gone YAZ-797
138 Extended comstack with outgoing IP YAZ-795.
139 For cs_create_host + cs_create_host_proxy the vhost may be followed
140 by a outgoing host/IP. Separator is blank.
144 Add YAZ_EXPORT to cql_transform_r fixes YAZ-793 . This issue fixes

170 Stop building debs for Ubuntu raring, quantal, oneiric.
172 CCL YAZ-781: for multiple use attributes in a specification the
173 generated RPN will perform @or on each term.
174 For spec: term u=31 u=1016
175 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
177 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
179 CCL YAZ-779: combo qualifier should allow for forward references
181 Fix buildconf.sh, automake too old on centos5 YAZ-778
182 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
183 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
184 accepts it without a warning.
188 GFS: client_query_charset conversion YAZ-777
189 This is a feature for Z39.50 clients that sends queries that are not
190 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
191 encoding given to UTF-8.
193 Echoed SRU arguments support YAZ-776
194 This is achieved with new function yaz_srw_get_pdu_e.
196 ZOOM: expire times set for redis/memcached YAZ-772
197 For both redis and memcached option --expire=seconds sets expire
198 time for a result-set/search. Default time is 600 seconds (10 minutes).
202 No [rest of output is omitted] limit for yaz_log YAZ-774
204 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
206 For ICU testing, pass -o to yaz-icu. This will test the
207 icu_iter_get_org_info function.
209 Fix null ptr reference for freeReplyObject YAZ-773
213 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
215 RPM: do not build with libmemcached support. The libmemcached library
216 on CentOS 5/6 does not work reliably for us (redis to the rescue).
218 configure: only allow libmemcached version 0.40 or later. That's the version
219 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
220 that's not an option, consider redis.
224 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
226 Fix zoom+memcached: present request out of range YAZ-767
230 CCL: add new qualifier r=omiteq which will omit relation=equals
231 for ordered relations. This should be used in combination with either
234 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
236 Solr: simplify yaz_solr_decode_response
238 Solr: use different local var for string manipulation
240 Solr: Get rid of hardcoded limit of extra_args
242 Solr: encode lucene query type YAZ-736
243 Make sure the queries are treated as traditional "lucene", because that's

250 Build packages for Ubuntu Trusty Tahr 14.04 LTS
252 wrbuf_cstr: fix off by one error.
254 wrbuf_buf: make it always return non-NULL
255 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
259 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
261 zoomsh: offer option -a apdulog
262 As we're used to from yaz-client and GFS based servers.
264 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
265 existing setting apdulog takes effect.
267 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
272 Add re-entrant CQL/Solr/RPN query conversion functions.
273 The re-entrant functions are: cql_transform_r,
274 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
275 These have same functionality as cql_transform,
276 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
277 return the additional infomration as WRBUF to make them re-entrant.
279 Remove CQL to Solr conversion and base solr_transform_t on
280 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
281 data structure as cql_transform_t.
283 cql2pqf utility allows RPN to Solr conversion
285 Fix assert in ZOOM when http connect fails YAZ-757
287 --- 5.0.22 2014/04/09
289 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
291 wrbuf_cstr: make it thread safe YAZ-753
293 yaz_log_init_file may take fd=<no> to open log file at the FD given.
295 --- 5.0.21 2014/03/21
297 Offer new utility function zget_AttributeList_use_string.
299 New conversion step, solrmarc, for record conversion module.
301 --- 5.0.20 2014/03/13
303 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
304 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
307 --- 5.0.19 2014/03/10
309 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
310 The standalone ZOOM sort was completely broken since 5.0.13.
312 ZOOM: generate event Connect rather than None for partial connect
313 (in fact getaddrinfo resolving).
315 ZOOM: only supply clientIP for InitRequest. Rather than for all
318 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
320 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
321 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
322 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
324 New "Facets" section in the documentation.
326 --- 5.0.18 2014/02/27
328 Call exsltRegisterAll in yaz_init_globals, so that all applications
329 using YAZ will have EXSLT things enabled.
331 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
333 Update various URLs to the re-organized SRU pages at LoC.
335 --- 5.0.17 2014/02/26
337 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
338 introduced in 5.0.12.
340 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
341 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
342 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
345 --- 5.0.16 2014/02/25
347 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
349 --- 5.0.15 2014/02/24
351 Fix gcrypt not properly initialized YAZ-740.
353 --- 5.0.14 2014/02/19
355 Describe memcached option for ZOOM.
357 ZOOM: throw present request out of range again YAZ-739
358 Was removed in YAZ 5.0.13.
360 --- 5.0.13 2014/02/18
362 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
363 with localtime_r when threads + fork is used (such as Metaproxy).
365 yaz-config: quote some RHS values (that might include blanks)
367 zoomsh: shows SearchResult-1
369 zoomsh: sortby command
371 zoomsh: use proper list of connections and result sets YAZ-725
373 Avoid yaz_log in sigterm handler for GFS YAZ-737
374 Logging is still performed, but outside sig handler.
376 New ZOOM C feature: result-set caching with memcached. Example:
377 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
379 Remove SSL via OpenSSL support YAZ-732
380 Also deprecate two functions from comstack that aren't working with
381 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
383 Revert "Bison: use %name-prefix directive rather than -p option"
385 --- 5.0.12 2014/01/22
387 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
389 SRU GET/Solr base URLs may hold additional ?args YAZ-729
390 ZOOM option extraArgs already does this, though. It seems useful
391 when dealing with Solr targets to limit by filter, eg.
392 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
394 Remove #fragment for HTTP request encoding YAZ-730
396 Doc: Update list of DLLs/LIBs
398 Doc: update href link to Unix utils and Git.
400 --- 5.0.11 2014/01/15
402 ZOOM: fix "lost connection" problem with servers that uses both squid
403 and another proxy behind it that returns Location headers with relative
406 zoomsh: do not use readline for stdin (no tty) YAZ-724
407 Just use fgets in that case. If the user hits Ctrl-D a new-line
410 zoomsh: empty command ignored YAZ-723
411 rather than performing exit of zoomsh.
413 yaz-url utility offers option -v to enable verbose mode.
415 yaz_url uses yaz_check_location and offers verbose mode.
417 Add new function yaz_check_location.
418 This function gets an absolute URI from Location (HTTP redirect).
420 cookie API: introduce yaz_cookies_reset
422 Update cql.y for newer bison YAZ-720
423 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
424 longer supported. Instead one must use %lex-param and %parse-param .
426 --- 5.0.10 2014/01/09
428 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
431 rpn2solr: support truncation left(2), left&right(3) YAZ-718
433 Mention SRU version 2.0 in yaz-client man page.
437 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
442 Make cs_parse_host public.A
444 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
445 introduced in YAZ 5.0.6.
449 Fix buffer corruption for yaz-ztest record fetch.
453 Allow yaz-ztest to return user-defined records (one record per file).
454 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
456 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
457 Use the stream write instead of odr_printf which has a 4K tmp buffer.
459 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
463 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
464 can read and write this format. For record format JSON, yaz-ztest returns
465 MARC-in-JSON records.
467 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
468 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
472 Improve error reporting for ICU chains YAZ-707
473 Report config element+rule when ICU status is "failure".
475 ZOOM: stop fetching if present response has no records YAZ-710
476 Some targets return less records than their hit count would suggest.
477 This prevents ZOOM from continuing to fetch records if any present
478 response has 0 records in the response.
480 Ensure that GFS calls exit if any listener fails YAZ-710
481 Before, if XML config was in use, it would start the default
486 yaz-ztest: -V shows version (like yaz-client -V)
488 New iconv encoding: danmarc YAZ-692
490 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
492 daemon: only wait for immediate child rather than all children. YAZ-704
494 yaz-client: fix setting of SRU record schema. If scheme was unset, it
495 could lead to invalid memory reference.
499 yaz-ztest returns schema for MARCXML test records. SRU require that
500 recordSchema for records.
502 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
503 instead of non-surrogate diagnostic. This is a per-record failure.
505 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
506 may refer to multiple listeners now. Attribute listenref is a comma separated
509 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
510 option is given for GFS, the dirname of filename (for -f) is used
511 as prefix for options such as cql2rpn, ccl2rpn, etc.
513 Content-Type charset fixes YAZ-701 . Do not inspect charset in
514 Content-Type header for SOAP when decoding SRU. The payload (XML)
515 itself tells what encoding it is. In response, never supply encoding
516 in Content-Type. The response payload (XML) tells what it is (with no
517 encoding in XML it's UTF-8).
519 HTTP decoding: allow blanks in URL paths YAZ-700
523 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
524 and facets. Ensure recordData and recordSchema are always present in
525 record element, because they are required.
527 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
530 Simplify in a lot of places using odr_strdupn.
532 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
536 Increase various buffers in GFS's statserv_options_block
537 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
538 This change makes many type-casts redundant, and, thus simplifies code.
540 Remove last bits of WAIS support.
542 Remove member 'size' from Odr_oct.
544 Slim down the public part of 'struct odr'. Most elements are not part
545 of struct Odr_private.
547 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
548 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
549 In particular facets are supported in both client - and server side.
550 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
551 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
552 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
553 both request/response). This is what a search handler in the GFS
554 will see (regardless of whether operating in SRU mode or Z39.50).
556 Changes to the srw.h (SRU/Solr) definitions include:
557 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
558 (char*), which replace union query and query_type (int). This is because
559 SRU 2.0 supports a queryType parameter. This also means that, to carry
560 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
561 x-pquery=PQFstring (extention parameter). The extension parameter
563 - New element, packing, that has information about SRU
564 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
566 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
568 New element, packing, in Z_SRW_explainRequest.
570 New elements in Z_SRW_scanRequest, queryType and scanClause.
571 These replace query_type and scanClase untion. This is similar to what
574 --- 4.2.69 2013/10/01
576 GFS: log when closing down - at least SIGTERM YAZ-684
577 Also change formatting WRT PID logging a bit.
579 Improve display of MARC records with multi-byte subfield IDs YAZ-695
580 In some rare cases subfield identifiers are multi-byte characters.
581 This will try to deterime length of those and split accordingly.
582 This affects display in line mode as MARCXML/MarcXchange. The encoding
583 of ISO2709 is the same.
585 Change inp argument to const for yaz_read_UTF8_char.
587 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
589 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
591 Better check of marc leader info YAZ-691
592 Problem is that some systems generate MARCXML/MarcXchange with
593 funny headers. These will not work if encoded as ISO2709.
594 Some tests produce new output, due to updated warning messages
596 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
598 yaz-client: display MAB records YAZ-689.
599 Thanks for Heiko Jansen for this patch.
601 New utility z_get_HTTP_Response_server which allows both HTTP server name
602 and HTTP server URL to be given in response.
604 Debian: do not depend on obs tcl8.3.
606 Debian: do not depend on obs libicu36-dev.
608 --- 4.2.68 2013/09/23
610 GFS: pass additionalSearchInfo to search memeber search_input if
611 given. Otherwise pass otherInfo. Request for facets and other search
612 related things will be passed there in future versions of YAZ.
614 New ZOOM setting, authenticationMode, which allows authentication
615 paramters to be encoded in the URL rather than via HTTP Basic auth.
618 rpn2solr: fix nested AND/OR handling. YAZ-685
620 Add comparison routines for some Z-types, such as NamePlusRecord,
621 RPNQuery, Query, RecordComposition and OtherInformation.
623 --- 4.2.67 2013/09/19
625 Don't decode MAB as MARC. Just like we don't attempt to decode
626 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
628 CCL: allow quoted terms for date ranges. YAZ-681
630 Introduce ccl_parser_qual_search. This function makes old function
631 ccl_qual_search, from YAZ 2, available again.
633 Add yaz_facet_list_to_wrbuf. YAZ-683
635 --- 4.2.66 2013/09/11
637 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
638 schema was given for search. YAZ-675
640 Add Solr date range searches. YAZ-621
642 --- 4.2.65 2013/08/22
644 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
646 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
648 ISO2709/MARC parse most octet aligned records; not just those that
649 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
650 MARC parse more records instead of just dumping as is. YAZ-670
652 ZOOM: proper caching for variations of record schema. YAZ-671
654 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
656 --- 4.2.63 2013/07/17
660 --- 4.2.62 2013/07/11
662 New utility z_get_HTTP_Response_details - an extended version of
665 New utility yaz_url_get_error which returns error message of last
666 failed yaz_url_exec call.
668 yaz-url and url functions: allow max HTTP redirects to be controlled.
670 New functions yaz_file_glob2, yaz_xml_include_glob.
671 These functions takes a flags parameter, which, for now only controls
672 whether to fail inclusion of a non-existing file (without glob
673 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
675 --- 4.2.61 2013/06/20
677 For MARC XML parsing, allow record without leader. A fake/default leader
678 is inserted and a warning is tagged with the record.
680 ICU: fix leak in in icu_iter_get_org_info.
682 --- 4.2.60 2013/06/14
684 ICU: fix bug in icu_iter_get_org_info (un-init variable).
686 --- 4.2.59 2013/06/11
688 Implement z_HTTP_header_remove.
690 --- 4.2.58 2013/06/11
692 ICU: Disallow 0 ptrs for some ICU string utilities.
694 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
695 returns original tokens (before normalization).
697 CCL: avoid z39.58/regex truncation when not needed. Apply only the
698 conversion of those masks, when absolutely necessary.
700 CCL: configurable masking character - @mask. Default masking character
703 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
704 full response anyway, so a Transfer-Encoding header will obstruct the
707 --- 4.2.57 2013/05/15
709 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
710 picking a socket. Problem is that some systems has IPV6 support, but
711 we can't create sockets for them, so we pick AF_UNSPEC first.
713 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
714 use content_len to determine resulting Content-Length in HTTP response
715 and NOT Content-Length supplied in headers by user.
717 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
718 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
720 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
723 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
724 with big endian and unsigned char (by default).
726 --- 4.2.56 2013/04/26
728 Fix yaz-client connect (crash in 4.2.55).
730 --- 4.2.55 2013/04/26
732 Fix proxy/host problem for ZOOM that could occur if unix sockets
735 New Debian package libyaz4-dbg.
737 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
738 differently in tcpip_close.
740 --- 4.2.54 2013/04/17
742 Windows installer of YAZ includes YAZ4J as a component.
744 CQL: allow "extra terms" again, by default. Thus, the CQL parser
745 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
746 and earlier. CQL parser may operate in strict mode where queries
747 not conforming to the standard BNF are rejected (syntax error).
748 Whether the CQL parser operates in strict mode is controlled with
749 cql_parser_strict . Strict mode enabled with option -S for utilities
750 cql2pqf and cql2xcql .
752 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
754 --- 4.2.53 2013/04/10
756 New charset, MARC-8c, which is like MARC-8 but allows control characters
757 0x01 through 0x1F, except ESC to be passed through verbatim.
759 Fix a problem with duplicate sub field character in MARC output. Problem
760 happened only when output was MARC-8 encoded.
762 --- 4.2.52 2013/04/03
764 yaz-ztest: Use hash for fake hit count. Before, random number was used.
765 This is problematic for unit tests using yaz-ztest. This patch also makes
766 a hash for CQL queries. For RPN, any term with a leading digit will be
767 treated as pseudu hit count (to force any particular hit count by a client).
769 yaz-ztest: return unique MARC dummy records. Beyond record offset
770 24, the author surname is patched with offset to make all records
773 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
774 on system wide default (/proc/sys/net/ipv6/bindv6only).
775 @4 binds to IPV4 only. @6 binds to IPV6 only.
777 Update CQL API documentation a bit
779 CQL: don't accept extra terms for queries. Makes the CQL parser
780 stricly conformant to the standard.
782 --- 4.2.51 2013/02/12
784 GFS: scan handler gets extra_args from request and may return extra
785 response data . That's for SRU only.
787 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
789 --- 4.2.50 2013/01/30
791 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
793 OPACXML: sync spelling of availabilityDate in XML to that of Schema
794 opaxxml.xsd. The schema had the correct spelling of this member always.
795 The ASN.1 was mis-spelled and still is (API change) - we are
796 not changing this. However, the OPAC to XML conversion had yet
799 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
802 New function, z_ext_record_oid_nmem, which is similar to
803 z_ext_record_oid but takes NMEM rather than ODR
805 --- 4.2.49 2013/01/18
807 ICU: New conversion element 'join' which joins tokens into one
808 with a custom character given by rule attribute.
810 --- 4.2.48 2013/01/10
812 New GFS search member: present_number. This is a hint to the
813 search handler how many records are going to be fetched immediately
814 following search. There's no guarantee that it's going to be the case,
815 since it depends on hit count (for Z39.50 piggyback) and whether errors
818 Make a few functions static (private). The functions getbyte_stream,
819 ungetbyte_stream and yaz_gets are now private. They were never declared
822 yaz-marcdump: exit(5) for serious decoding errors
824 ISO2709 decoding: be more picky WRT header
826 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
827 was only used as to indicate that next-result-set-position should be
829 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
830 Based on patch from Ashley Sanders.
832 Make some functions static/private in PQF parsing. Those functions were
833 never declared in a public header and so should not be in use by
834 applications based on YAZ.
836 --- 4.2.47 2012/11/23
838 ZOOM: special options to control APDU logging.
839 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
840 logging of APDUs until "saveAPDU" option is set again. If logging is
841 already enabled the effect is that current APDU buffer is cleared.
842 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
843 logging (default behavior on new connection).
844 The APDUs sent/received can be obtained by using
845 Using ZOOM_connection_option_get(c, "APDU") or
846 ZOOM_connection_option_getl(c, "APDU", &l).
848 GFS: relay implementation_version from backend
849 From 3.0.40 and later, implementation_version from backend was
850 not used in init response at all.
852 --- 4.2.46 2012/11/15
854 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
855 mode at all. Probably never did.
857 Make a new version of ztest.pem that, at least, is not expired.
859 --- 4.2.45 2012/11/13
861 Fix description of CCL directive 'case'.
863 More tight checking of form arguments (yaz_uri_to_array). Makes
864 YAZ better at rejecting big and/or bad POSTs.
866 SRU decoding does not report more than up to 10 invalid arguments.
868 rpn2cql: less quotes in generated terms. Semantics unchanged, but
869 it's prettier this way.
871 --- 4.2.44 2012/10/25
873 New utility yaz_decode_init_diag. Defined in proto.h.
875 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
876 given for unix local socket.
877 The COMSTACK string for doing so is:
880 unix:/myfile:tcp:localhost:9999/mybase
881 unix:/myfile:localhost:9999/mybase
882 unix:/myfile:http://fakehost/mybase
884 debian: Use dpkg-buildflags in build process.
886 --- 4.2.43 2012/10/19
888 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
889 global's SRU service uses a recordPosition scheme starting from zero.
890 First record's position should be one
891 according to the standard.
893 --- 4.2.42 2012/10/18
895 Allow more namespaces for SRU. This is to allow, for example, an
896 incorrect namespace returned from server
897 http://services.igi-global.com/sru .
899 Minor fixes for compilation on Windows.
901 --- 4.2.41 2012/10/11
903 daemon: log total number of bad signals from child on stop so that it
904 is more easy to spot problems with child worker processes.
906 retrieval: empty backend name attribute omits element set
907 from being used in retrieval.
909 --- 4.2.40 2012/10/04
911 Implement Solr sort strategy "solr", similar to sru11 sorting.
912 This will implement the correct parameters on Solr requst to do
915 --- 4.2.39 2012/09/28
917 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
920 MARC: Extra/missing indicator handled for MARCXML.
921 The indicator length is given in header and is the same for the
922 whole record. If attributes ind1, ind2 are missing, then content
923 character defaults to blank. Extra indicator attributes (beyond)
924 indicator length are treated as an error.
926 Reformat: delete trailing whitespace
928 --- 4.2.38 2012/09/17
930 MARC: fix non-ASCII characters for leader. This is to ensure we can
931 generate XML in UTF-8.
933 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
934 in one node with structure word.
936 --- 4.2.37 2012/09/04
938 yaz-json-parse: JSON output may be pretty printed by using option
941 Increase default value of max message for Z39.50 Init for GFS, ZOOM
942 and yaz-client. Old value was 1 MB. New value is 64 MB.
944 --- 4.2.36 2012/08/22
946 yaz-client: don't display bogus records from SRU servers. Some SRU servers
947 return more records than given by *maximumRecords*. Skipping those in
950 record_render: simplify buffer return handling and fix at least one bad
951 memory reference, that broke the test_embed_record sometimes.
953 Allow http://user:pass@host notation for yaz_url_exec.
955 zoomsh: allow shell command to be executed. Via the system(3) call.
957 yaz_poll: Allow num_fds == 0
959 yaz-client: fix bad encoding of "itemorder item". The itemorder
960 item <no> - command forgot to use length of encoded Item Request
961 package. Error present since YAZ 3.
963 yaz-ztest: fix bad usage of session handle. Bug was introduced when
964 result sets were saved (271a9c83).
966 SRU recordPacking: guess record packing in response rather than looking
967 at the recordPacking element which, OF COURSE, changed semantics in SRU
970 Decode SRU 2.0 responses. The official namespace for responses, according
971 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
972 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
973 nature.com's server, however, usee namespace
974 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
975 we are now using a glob-expr to match up the namespace. ZOOM C and
976 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
977 I can not find a single real example showing the "real" namespace in
978 the documentation from OASIS. The namespace for requests is different
979 from responses, but this is not added to YAZ yet, when we don't encode
982 --- 4.2.35 2012/06/26
984 zoom/record_render: add support for Base64 decoding fo MARC records
985 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
986 which will decode base64 + ISO2709 marc-8 encoded material from text node
989 --- 4.2.34 2012/06/07
991 Add missing definitions ZOOM_resultset_get_facet_field_by_index
992 and ZOOM_resultset_facets_names.
994 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
997 Change APDU dump printing to avoid long leading blanks. For levels 16
998 or larger the level is shown and the indentation is truncated but
999 recursed with modula 8. This makes it still reasonable easy to read
1000 - even for nested BER dumps.
1002 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
1003 return 0 (incomplete package) in case where the BER package was
1004 considered too nested (return value of -2).
1006 dumpber: lines of level 15 are not indented further. Two spaces per
1007 indentation; indentation 15 or more is indented to a fixed indentation
1008 and augmented with a level=<no> indication.
1010 zoomsh: increase max size of command+args
1012 GFS: No limit in RPN buf size in CQL to RPN conversion.
1014 --- 4.2.33 2012/05/09
1016 New function for daemon utility, yaz_daemon_stop .
1018 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
1020 --- 4.2.32 2012/04/25
1022 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
1023 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
1025 --- 4.2.31 2012/04/23
1027 YAZ daemon utility relays SIGUSR1 to child process.
1029 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
1030 would result in en empty database list - which in turn would result in
1031 encoding failure for search.
1033 Fix reading beyond string in yaz_sort_spec.
1035 --- 4.2.30 2012/04/11
1037 Add two new SRU diagnostics:
1038 236: Access to specified database denied
1039 1015: Init/AC: Maximum number of simultaneous sessions for Userid
1041 Document the very useful ZOOM-C option "apdulog".
1043 CQL to RPN: term may be passed through verbatim. This is enabled with
1044 truncation.cql . The assumption being that the term is already CQL.
1046 --- 4.2.29 2012/03/20
1048 record_conv: leader spec may be given for marc element.
1049 The leader spec is given as attribute leaderspec for element marc.
1050 For example to convert a MARC21 record from MARC-8 to UTF-8:
1051 <marc inputformat="marc" outputformat="marc"
1052 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
1054 record_conv: allow user-XSLT params. For example:
1055 <xslt stylesheet="MARC21slim2DC.xsl">
1056 <param name="myparameter" value="myvalue"/>
1057 <param name="otherparameter" value="othervalue"/>
1060 record_conv: fix error handling for missing marc charsets.
1062 CQL: fix extra terms in wrong order.
1064 --- 4.2.28 2012/03/06
1066 record_conv: modify new API for conversion types. The conversion types
1067 may be passed in new functions yaz_record_conv_configure_t and
1068 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
1070 Avoid mixed statement/variable declare; fixes compilation with Visual
1073 --- 4.2.27 2012/02/28
1075 Add non-standard SRU diagnostic: 235: "Database does not exist".
1076 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
1077 Update SRU to Bib-1 diagnostic maps accordingly.
1079 CCL: add two new diagnostics for unsupported masking. The new
1080 diagnostics are: "Embedded truncation not supported" and
1081 "Single charcacter mask not supported".
1083 --- 4.2.26 2012/02/23
1085 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
1087 --- 4.2.25 2012/01/11
1089 Build YAZ for Ubuntu Oneiric.
1091 CCL: allow parantheses for proximity operands. For example CCL query
1092 (a) % (b) is now allowed.
1094 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
1095 marked dead, rather then being destroyed. If not, the session memory is
1096 being free'd before the search/scan handler is finished. Also destroy
1097 'request' memory in request_release rather than in various places,
1098 which resulted in leaks from time to time.
1100 --- 4.2.24 2011/12/21
1102 cql_sortby_to_sortkeys: honor sort prefix.
1104 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
1105 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
1106 The rpn2cql family of functions now always returns quoted CQL terms.
1108 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
1110 --- 4.2.23 2011/12/15
1112 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
1113 sequence is treated as one. For example, &&a=b&&&c& is identical to
1116 --- 4.2.22 2011/12/05
1118 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
1119 APDUs for a connection to a WRBUF.
1121 --- 4.2.21 2011/11/23
1123 Fix cql_sortby_to_sortkeys. Completely broken before.
1125 Make CCL's @truncation work again.
1127 --- 4.2.20 2011/11/09
1129 New ZOOM connection setting: tproxy. It's like proxy, but does not
1130 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
1131 to set resolved address + port for a connection outside ZOOM itself.
1133 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
1135 --- 4.2.19 2011/11/07
1137 Fix uninitialized variable in Solr spell support (could cause SEGV
1138 for SRU response decoding).
1140 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
1141 back-end's addinfo through into the ZOOM response addinfo.
1143 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
1144 they are separated by a colon and a space rather than simply
1147 --- 4.2.18 2011/10/28
1149 Add support for Solr spell-checking/suggestions through ZOOM.
1150 If a Solr target has been configured correctly for spelling-checking
1151 and suggestions, these will now be returned on the ResultSet option
1152 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1154 --- 4.2.17 2011/09/28
1156 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1157 with a flag whether to substitute escape sequences or not.
1159 --- 4.2.16 2011/09/22
1161 Fix nmem_strsplit_escape to substitute escape char properly.
1163 New option for zoomsh -e , which makes it abort on first error and
1164 return process exit code to indicate success/failure.
1166 YAZ options utility supports special option -- which makes all it treat
1167 all following arguments as non-options.
1169 --- 4.2.15 2011/09/16
1171 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1172 searched if absolute filename is given.
1174 Fix conv_xslt() error-reporting when stylesheet is not found.
1175 (The value of fullpath is meaningless in this situation.)
1177 --- 4.2.14 2011/09/07
1179 Fix problem in CQL sort node creation: un-initialized memory.
1181 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1182 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1183 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1186 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1187 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1189 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1190 will make it possible to use both single-character mask (#) and wildcard (?)
1191 in CCL . Throw diagnostic for left truncation because that is not supported
1194 --- 4.2.13 2011/09/01
1196 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1197 cases using escapes (\-sequences) and masking.
1199 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1200 would result in a read one byte beyond string.
1202 rpn2ccl may use Z39.50 masking for terms (t=z).
1204 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1206 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1207 not --cppflags (which seeems like an error in icu-config).
1209 --- 4.2.12 2011/08/27 RPM package only
1211 cql2ccl: fix conversion of terms: operator characters were not
1214 --- 4.2.11 2011/08/25 RPM package only
1216 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1217 CCL parser will map both # and ? to their regular expression
1218 quivalents (. and .*).
1220 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1221 of reserved CQL characters.
1223 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1224 is, so that they are passed through.
1226 --- 4.2.10 2011/08/24
1228 ZOOM SRU mode: more aggressive re-connect.
1230 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1231 made available as a utility function, declared in <yaz/logrpn.h>
1233 rpn2cql_structure() supports proximity nodes (except that the Type-1
1234 proximity node's "exclusion" binary is ignored, as there is no way to
1235 express that in CQL). Fixes bug #4564.
1237 --- 4.2.9 2011/08/18
1239 Fix SEGV that could occur if set command of zoomsh was given without
1240 value (2nd argument).
1242 Fix SEGV that could occur if unsupported transport was given for
1243 COMSTACK - say https (when SSL was unavailable).
1245 Build yaz-url on Windows too.
1247 --- 4.2.8 2011/08/11
1249 New utility to get web content. Header is url.h. A command line tool
1250 yaz-url is part of the distribution and packages.
1252 Fixes for SSL COMSTACK (when gnutls is in use).
1254 New functions yaz_base64{encode,decode}. Header is base64.h.
1256 --- 4.2.7 2011/08/03
1258 ZOOM C includes HTTP response buffer as additional info if it fails
1259 to decode the SRU response.
1261 Make wrbuf_json_puts available.
1263 --- 4.2.6 2011/07/28
1265 zoom: throw diagnostic for invalid value for option "sru". Before a
1266 bad SRU request was sent.
1268 Adding new utility wrbuf_vp_puts.
1270 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1272 --- 4.2.5 2011/07/21
1274 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1275 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1276 redirect was used at the same time.
1278 MARC line mode decoding: be less picky about length given - first
1279 5 digits of header that is.
1281 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1283 Changes to decoding of SRU records: a record with recordPacking=xml is
1284 modified with a new root element <yaz_record> if the recordData contains
1285 multiple children elements. This is to make the record XML parseable
1288 RPN to Solr conversion: encode special characters.
1290 Generic Frontend Server: fix uinitialized member, stepSize.
1292 --- 4.2.4 2011/06/21
1294 Fix a bug in SRU decoding of records.. The database records stored
1295 had un-initialized memory, but it would only be seen with yaz_record_render
1296 and type_spec="ext" .
1298 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1300 --- 4.2.3 2011/06/17
1302 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1304 --- 4.2.2 2011/06/10
1306 Add new utilities to convert from CQL to CCL . These utilities have
1307 prefix cql_to_ccl defined in cql.h.
1309 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1310 lead to memory heap corruptions when ICU utilities were in use.
1312 --- 4.2.1 2011/06/07
1314 Make compilation work without Libxml2.
1316 yaz-client: remove redundant blanks in display of searchResult-1 term
1319 --- 4.2.0 2011/05/18
1321 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1322 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1324 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1325 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1326 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1327 Note that the CQL sortby spec is only converted when the GFS is already
1328 converting from CQL to RPN (cql2rpn element).
1330 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1331 specify whether to collapse delimitors or not. The existing nmem_strsplit
1332 do collapse (collapse parameter = 1).
1334 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1336 Rename internal func yaz_use_attribute_create. While non-static, this
1337 function is not declared in a public header.
1339 --- 4.1.7 2011/03/15
1341 Add -lCrun when linking with ICU on Solaris.
1343 More quicks character set conversions for OPAC records.
1345 --- 4.1.6 2011/03/10
1347 fix problem with record_render: records were converted (character set
1348 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1350 --- 4.1.5 2011/03/08
1352 SRU: add methods for handling DADS SRU-proxy facets.
1354 Separate OPAC record character set for ZOOM_record. yaz_record_render
1355 allows a character set given as charset=from/opacfrom,to where 'from' is
1356 the character set of a bibliographic record, 'opacfrom' is character set
1357 of OPAC record and 'to' is the target character set.
1359 --- 4.1.4 2011/02/21
1361 yaz-client: show may XML format records. Command show followed by 'format'
1362 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1365 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1368 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1370 --- 4.1.3 2011/01/27
1371 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1373 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1374 this package can be distinguished from other vendors.
1376 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1377 as determined by configure
1379 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1381 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1382 returns no error and no record, the present request is considered
1383 partial (only a subset of the records could be returned by backend), and
1384 so it is appropriate to set Present Status to partial-4.
1386 --- 4.1.2 2010/11/02
1388 Move yaz-config man pages to section 1.
1390 More documentation about Solr.
1392 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1393 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1394 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1395 peers on some Linux systems. However, in general that does not work
1396 so YAZ can not rely on that to work. Debian changed behavior in this
1397 respect from Debian lenny to Debian squeeze (still testing as of Oct
1399 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1401 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1403 --- 4.1.1 2010/10/05
1405 Fix yaz-config output: echo_source not set correctly by configure.
1407 --- 4.1.0 2010/10/05
1409 Solr Web Service support for yaz-client and ZOOM.
1411 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1413 --- 4.0.12 2010/08/17
1415 Z39.50 facet support. Facet specifications are passed for search in
1416 other-information with ASN.1 as defined in facet.asn and OID
1417 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1418 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1419 3 is limit (number of entries to get in response). yaz-ztest returns
1420 dummy facets if a client asks for them.
1422 --- 4.0.11 2010/07/09
1424 CCL fixes: bug 2895 and bug 3539.
1426 GR1-display: add comma in display - was removed by mistake in
1429 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1431 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1433 --- 4.0.10 2010/06/18
1435 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1436 result set from a connection. The result set will be on its own
1437 thereafter; no operations on it will perform retrievals from a target.
1438 Only cached copies are returned.
1440 ZOOM C:fix case for HTTP servers responding with Connection:close.
1441 Ensure that if there is a current task it is resumed (like fetching
1442 more records in a result set) . Bug #3484.
1444 PQF parser: use odr_atoi for Odr_int (not atoi)
1446 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1447 values that contain any non-digits are treated as string attributes
1448 (previously decoding only checked for leading character ([0-9]). PQF
1449 encoding: attribute string values are not surrounded by double-quotes.
1451 --- 4.0.9 2010/05/21
1453 New utility for managing threads - thread_create.h.
1455 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1456 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1457 but YAZ' implementation do.
1459 Fixes for yaz_cond-functions on Windows 7.
1461 DLL export more symbols.
1463 zoomsh: show record do NOT render opac.
1465 Remove *.la files from Debian and RPM packages.
1467 --- 4.0.8 2010/05/11
1469 Debian package libyaz-dev depends on libgnutls-dev again (was
1470 removed in YAZ 4.0.6, but due to Libtool it is still needed
1471 even though yaz-config do not list libgnutls libs).
1473 ZOOM: Use only one WRBUF for returning string results for
1474 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1476 ZOOM: ZOOM_connection do not use a shared pointer to
1477 ZOOM_resultset after ZOOM_resultset is destructed by
1478 user. Reverts to YAZ 4.0.4 behavior.
1480 --- 4.0.7 2010/05/04
1482 record-conv: fix problem with at least one XSL conversion -
1483 due to probably incorrect usage of XML XSL documents.
1485 --- 4.0.6 2010/04/29
1487 Fix yaz-config for static mode and the use of SSL (gnutls).
1489 --- 4.0.5 2010/04/29
1491 Forward decl timeval struct in mutex.h and gettimeofday.h.
1493 yaz-config: fix 'static' mode linking.
1495 --- 4.0.4 2010/04/28
1497 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1498 are wrappers for pthreads or Windows. For Windows these are put in
1499 a separate DLL: yaz_cond4.
1501 libyaz.la (whole source) is compiled with thread. If thread support
1502 is enabled enabled, all source of YAZ is compiled with treading support.
1503 This allows core utilities such as yaz_log to use thread facilities.
1504 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1505 thread utilities. This commit moves mutex utilities (mutex.c) from
1506 libyaz_server.la to libyaz.la.
1508 yaz-json-parse displays leading text until error.
1510 --- 4.0.3 2010/04/09
1512 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1513 patch from Giannis Kosmas.
1515 SRU: no longer URL encode SRU database. The URL for an SRU server is
1516 a URL and such is alreeady encoded - at least when given with leading
1517 http:// or https://. This reverts behavior to YAZ 3.0.50.
1519 Support for new MARC XML notation TurboMARC which like MARCXML is a
1520 complete representation of MARC/ISO2709.. This one, however, is more
1521 compact and allows for faster processing with XSLT. TurboMARC can be
1522 used in the marcdisp.h API, from the yaz-marcdump utility and from
1525 yaz-ztest can be configured - via the database - to perform certain
1526 delays when it performs operations search, present and single record
1527 fetch. This allows testers to make yaz-ztest act as a real or even slow
1528 Z39.50 server. Refer to the yaz-ztest man pages for details.
1530 --- 4.0.2 2010/03/09
1532 wrbuf_destroy allows NULL WRBUF passed to it.
1534 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1536 Add ZOOM_connection_close.
1538 No fixed size buffers for ZOOM shell - bug #3257.
1540 tstodr: make it work on s390 platform.
1542 New icu iterator-functions. The new icu_iter-functions makes it possible
1543 to use ICU chains from many threads.
1545 yaz-client: better syntax check for show command.
1547 --- 4.0.1 2010/01/26
1549 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1552 New simple local-file XML include facility which allows file glob-patterns.
1553 Refer to yaz/xml_include.h.
1555 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1558 ZOOM_record_get supports new parameter "format" which makes it format XML
1561 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1562 JSONText in ECMA-262) is JSONValue, not JSONObject.
1564 --- 4.0.0 2010/01/20
1566 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1567 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1569 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1570 POSIX/Unix builds .so with major version 4.
1572 Remove old LOG_-defines from log.h. They have been obsolete and
1573 undefined by default for the last 5 years.
1575 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1577 GFS: Remove socket (int *fd) from search_rr handler. The socket
1578 descriptor ptr is a facility that allowed a search handler to supply
1579 a socket which would serve as a callback - when search was complete.
1580 This facility has now been in use for years.
1582 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1583 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1584 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1585 returns 'const char *' rather than 'char *. The returned string is
1586 read-only and should not be modified by applications. COMSTACK cs_close is
1587 now a void function - it no longer returns int. No applications check for
1588 the value and the implementations has always returned 0.
1590 ZOOM: use size_t for scan hit counts and str size. Functions
1591 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1592 occ (hit count) and len (string length) are now of type size_t pointer
1593 rather than int pointer. This is to be able to represent large hit counts
1594 and to also just to use the proper type for string length (strlen result).
1596 New JSON parser. Refer to include/yaz/json.h .
1598 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1599 Used to be int in some cases. Many wrbuf_-functions used to return an int
1600 indicating some length.. These return values were never used. And so they
1603 ODR: odr_malloc, odr_total now takes size_t for size.
1605 clone_z_type: fix leak; occurred for encoding failures.
1607 --- 3.0.52 2009/12/03
1609 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1610 bug was introduced in 3.0.51.
1612 --- 3.0.51 2009/12/02
1614 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1616 tcpip comstack: fix leak for getaddrinfo.
1618 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1619 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1620 Decoding of SRU "path" database is performed by private function
1621 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1622 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1624 yaz-client: honor base command for SRU. Change when database setting
1625 is applied for SRU and ensure it is kept when a connection is reset.
1626 Change also the way errors are displayed or SRU (decoding of packages).
1628 --- 3.0.50 2009/11/02
1630 Add support for extra request / response data for SRU codecs and GFS.
1631 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1632 for extra data response buffer and length. For the GFS, both request
1633 and response data (XML) is carried in extra_args and extra_response_data
1634 for the search handler. Patch by Ko van der Sloot.
1636 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1637 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1638 10010). This fixes bug #2113.
1640 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1641 cmdfile included a 'quit' command that would result in a memory violation.
1643 --- 3.0.49 2009/10/01
1645 Make a number of functions defined in xmlquery.c static. These have
1646 never been declared in a public header file (yaz/xmlquery.h) and was
1647 made public by mistake.
1649 Improve speed of character conversions (iconv utilities). This makes
1650 conversions from MARC-8 faster.
1652 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1653 unless type desired is "raw". This will prevent type "xml" from
1654 returning ISO2709 .. Which obviously can not be XML parsed.
1656 Fix memory leak in ZOOM that would occur if option apdulog was used
1657 on a re-used connection.
1659 Frontend server logs HTTP requests.
1661 Frontend server now sends Z39.50 close when it times out (sesssion has
1662 been idle for too long). Versions 2.0.30 and earlier also sent close.
1663 But due to a mistake this was disabled in all versions after that, i.e.
1664 the server would just close the socket immediately.
1666 yaz-client emits a better message when receiving an unrecognised
1667 userInformationField.
1669 Skip zero-length subfields when decoding ISO2709. This rare case happens
1670 if a record has two FS characters in a sequence. Without this patch
1671 there would be a reference beyond char array in using_code_len fragments
1674 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1676 --- 3.0.48 2009/08/28
1678 The show command offered by the zoomsh command now takes a 3d optional
1679 parameter type which is what is passed to ZOOM_record. If the type
1680 argument is omitted, "render" is used.
1682 RPN to CQL conv may use USE string attributes (bug #2978).
1684 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1686 --- 3.0.47 2009/07/08
1688 Function yaz_xml2query allows a diagnostic element in the PQF XML
1689 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1690 code and additional info respectively.
1692 The BER BOOLEAN is now the integral type Odr_bool which still happens
1693 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1694 typedef'd to Odr_int. This is still an integral 'int', but it may be
1695 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1696 ASN-1 compiler as well as programs has been updated to use the new types.
1698 --- 3.0.46 2009/06/08
1700 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1701 only the bibliographic record was rendered. For type=opac, an OPAC
1702 record is only returned if it is present.
1704 iconv: small fix for encoding of advancegreek.
1706 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1708 yaz-client: option auto_reconnect=on really reconnects.
1710 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1712 server: avoid null ptr ref for for yaz_poll errors.
1714 build: fix RPM build for RHEL 5.3.
1716 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1718 --- 3.0.45 2009/03/31
1720 Fixed bug #2709: TCP connect returns Invalid argument.
1722 Fixed compilation for mingw.
1724 Honor charset for raw records (ZOOM_record_get).
1726 Fixed use of errno for threaded mode that was seen on Solaris 10.
1728 Fixed argument passing with blanks in value for Windows Service.
1730 Disable YAZ' own log rotate by default (no 1 GB limit).
1731 The variable l_max_size which specifies the log file limit is set to 0
1732 (DISABLED): This is due to the fact that YAZ is most often deployed using
1733 logrotate. Also YAZ can not perform log rotate because of unsufficient
1734 permissions (setuid).
1736 --- 3.0.44 2009/02/17
1738 List supported encodings in man page for yaz-iconv.
1740 Fixed missing SSL libs for --libs output
1742 Re-established OID record syntax application-xml. Nobody should use it
1743 but we don't want to change soname because of this symbol being absent.
1745 --- 3.0.42 2009/02/02
1747 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1749 Added member named_result_sets for init handler struct for the GFS. This
1750 allows a server to disable named result sets.
1752 Removed OID record syntax application-xml.
1754 Added support for rule-based transliterator for ICU wrapper of YAZ.
1756 Fixed bug #1902: yaz-icu XML output.
1758 Make YAZ checks Emacs friendly.
1760 BITSTRING value shows value. Bug #2346.
1762 ISO2709 decoding: skip control characters from indicator data.
1764 Omit sort key by default in yaz-icu's output.
1766 Allow combined single char options (again) for YAZ' options function.
1768 Utility yaz-marcdump got option to display YAZ version (-V).
1770 Allow YAZ to use ICU 3.4.
1772 Added new ICU test case which illustrates removal of diacritics.
1774 --- 3.0.41 2008/12/29
1776 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1778 --- 3.0.40 2008/12/29
1780 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1783 Fixed bug #2352: yaz-marcdump crashes for certain record.
1785 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1787 Added support for Danmarc2 to UTF-8 conversion.
1789 Added support for ISO5426 to UTF-8 conversion.
1791 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1792 implementation version.
1794 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1796 --- 3.0.38 2008/11/10
1798 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1799 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1801 ZOOM C now interprets databaseName option for ZOOM connection as path
1804 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1806 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1808 Dummy Libxml2 types no longer defined in headers of YAZ'.
1810 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1813 --- 3.0.36 2008/09/26
1815 Various ODR chapter fixes.
1817 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1819 Added missing source for Windows compilation, mutex.c.
1821 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1823 For SRU connections in ZOOM all records up to "count" are now fetched.
1825 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1826 in Windows due to bad error handling for Libxml2.
1828 Added facility for sending arbitrary records (ASN.1 any) using
1829 ZOOM C's Extended service update. Patch by Sam Reynolds.
1831 New options for ZOOM C's connection, logapdu which makes ZOOM log
1834 --- 3.0.34 2008/06/18
1836 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1838 --- 3.0.32 2008/06/12
1840 Fixed memory violation that could occur when decoding UTF-8. This bug
1841 was only present in 3.0.30 of YAZ.
1843 --- 3.0.30 2008/06/06
1845 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1846 GNU TLS is used by default (if found).
1848 yaz-ztest returns OPAC records if a client asks for OPAC.
1850 Improved speed of MARC-8 encoding.
1852 Added support for lossy and loss-less MARC-8 encoding.
1854 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1856 Added new Windows Service wrapper (sc).
1858 yaz-client's itemorder command may now send a file.
1860 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1862 Added new function yaz_log_xml_errors.
1864 Allow (but warn) unknown XML attributes in MARCXML parsing.
1866 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1868 The UTF-8 to MARC-8 conversion now uses a different set of characters
1869 for Greek symbols. Bug #2120.
1871 --- 3.0.26 2008/02/21
1873 Added yaz_daemon (daemon.h).
1875 Fixed bug #2068: pkg-config trouble
1877 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1879 --- 3.0.24 2008/01/28
1881 Document --with-xml2 option.
1883 Added OPAC XML XSD (etc/opacxml.xsd).
1885 Allow glob mask for name attribute in retrieval element for the
1886 generic frontend server's retrieval facility.
1888 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1889 except POLLIN/POLLOUT.
1891 Fixed error handling in cs_listen. Bug #2037.
1893 --- 3.0.22 2008/01/20
1895 Fixed version in yaz/yaz-version.h.
1897 Fixed bug #2027: Crash when closing connection.
1899 Changed configure so that ICU support is only enabled if only ICU
1900 and Libxml2 is available (because the ICU chain is XML based).
1902 --- 3.0.20 2008/01/15
1904 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1905 is built. Only this DLL depends on the ICU runtime.
1907 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1908 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1910 Changed license of CCL module to 'Revised BSD'. After consultation with
1911 remaining members of the original EUROPAGATE consortium, we are re-issuing
1912 the CCL module without a separate license. The software was developed by
1913 Index Data as part of a research project. The special license was included
1914 to help feed usage information back to the project consortium to support
1915 project evaluation. At this time, the project consortium has long-since
1916 disbanded, and the majority of the original principals have retired. At the
1917 same time, we have significantly modified the software during the following
1918 years, to the point where very practically no original code remains. To
1919 simplify re-use of the software, we have contacted those members of the
1920 consortium who could be reached, and agreed to re-issue the module as a
1921 proper part of the YAZ package.
1923 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1925 CQL closer to being version 1.2 compliant. CQL also allows free-form
1926 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1929 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1930 bug could make Extended services handling crash in the ZOOM layer. This
1931 bug was only present in YAZ 3.0.18.
1933 --- 3.0.18 2007/12/19
1935 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1938 yaz-marcdump reads and writes collection wrapped records.
1940 Handle OPAC for record conversion module.
1942 Fixes for ICU wrapper.
1944 Allow ICU libs to be controlled with --with-icu .
1946 --- 3.0.16 2007/11/12
1948 Added yaz_poll which is a wrapper for select/poll. When poll is available
1949 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1950 sockets to be in use.
1952 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1953 functionality through an XML based configuration (ICU chain). This system
1954 is useful for search facilities such as Pazpar2 and Zebra that needs to
1955 perform tokenization of indexed material. The ICU code in a separate
1956 library libyaz3_icu.a.
1958 Added HTTP tunnel facility for COMSTACK, bug #1752.
1959 This is a facility that allows a Web proxy, such as squid, to tunnel
1960 Z39.50 traffic. This facility is "transparent" to must applications
1961 using YAZ. It's enabled by using pseudo transport connect: followed by
1962 the proxy address, followed by command, then follwed by he regular
1963 "virtual" addresss. For example,
1964 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1966 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1968 --- 3.0.14 2007/09/21
1970 Fixed bad memory reference in ZOOM_record - cuased by member not being
1971 initialized. This was a problem only in YAZ 3.0.12.
1973 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1974 fields were not removed.
1976 Changed the way C code is generated from codetables.xml. Made a MARC-8
1977 conversion trie for each characterSet section rather than codeTable.
1978 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1979 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1981 --- 3.0.12 2007/09/12
1983 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1984 from ZOOM_record_error).
1986 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1988 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1990 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1992 Better SRW-to-Bib-1 diagnostic mapping.
1994 ZOOM C and yaz-client announces SRU version 1.2 by default.
1996 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1999 Fixed in yaz_sru_decode to allow other version than 1.1.
2001 --- 3.0.10 2007/08/22
2003 Added support for SRU scan for ZOOM.
2005 Added support for the use of the older versions or Extended Service
2006 Update in ZOOM. To faciliate this, an option "updateVersion" may be
2007 set to the version , 1=first, 2=second, 3=third. The third version is
2008 what ZOOM C has used so far. And that, obviously, is the default.
2010 Added support for CCL queries in Z39.50 queries sent to the GFS (and
2011 therefore in Zebra and in SimpleServer-based applications). The new
2012 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
2013 qualifier file used to transform incoming CCL queries into Type-1 RPN,
2014 which is passed into the back-end search callback function.
2016 Added support for HTTP Basic authentication in clients: the SRU/W
2017 codec encodes the username/password elements of the PDU structure
2018 appropriately, and these may be set using the "user" and "password"
2019 options in ZOOM-C applications (the same options that are used for
2020 Z39.50 authentication).
2022 --- 3.0.8 2007/06/25
2024 Fixed bug #1208: SSL appears to be broken in ZOOM.
2026 Fixed bug #1206: Libxml2 include path weirdness.
2028 Added oid_name_to_dotstring.
2030 Allow elementSetName to be specified for ZOOM C record update.
2032 Allow waitAction to be specified for ZOOM C based for Extended Services.
2034 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
2035 syntax OID. Bug introduced in YAZ 3 series.
2037 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
2039 --- 3.0.6 2007/06/06
2041 Fixed bug #1157: yaz-client does not read .yazclientrc from current
2042 directory. yaz-client now reads commands from file given by option -f
2043 if specified; then tries to read .yazclientrc in current directory.
2044 Failing that, it reads .yazclientrc from user's home directory.
2046 Added support for correlationInfo Note and ID for Record Update via
2049 Added yaz-client command querycharset which specifies character set for
2050 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
2051 (termListAndStartPoint).
2053 Charset ISO5428:1984 is an alias for ISO5428-1984.
2055 Implemented a way to perform scan in a result set using Z39.50. This
2056 is achieved by attaching the result set name in the characterInfo
2057 (type InternationalString) of OtherInformation in the Scan Request PDU.
2058 The result set is identified in the otherinformation by the new OID:
2059 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
2060 This allows for scan in result set and faceted search . Zebra did some
2061 of this in the APT term using attribute type 8 and value being result
2062 set. Using the OtherInformation approach for this is cleaner and easier
2063 to work with in proxies and the like. This facility can be used in
2064 yaz-client using new command setscan which takes a result set as first
2065 argument, start position (APT) as second.
2067 Changed decoding of SRU XML packed records to deal with servers that
2068 have recordData with XML data with multiple root nodes. Also make
2069 comparison for recordPacking case insensitive. Again, one server
2070 returns "XML" where others return "xml".
2072 For SRU responses allow Content-Type application/xml as well as text/xml.
2074 --- 3.0.4 2007/05/21
2076 Fixed bug in character set conversion of BER strings. Bug introduced
2079 --- 3.0.2 2007/05/08
2081 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
2083 For OID class, use oid_class consistently.
2085 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
2088 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
2089 character set for bibliographic information interchange". By Giannis Kosmas.
2091 Added documentation on new OID API.
2093 --- 3.0.0 2007/05/02
2095 Changes to generic frontend server interface: added new member
2096 'query_charset' for bend_initrequest structure. A backend init handler
2097 should set this member to its native character set for query terms.
2098 When defined, the frontend server logic will announce this character set
2099 to a client if the negotiationModel bit is set by the client. All server
2100 implementors are encouraged to specify this. If a backend server does not
2101 specify this a warning is issued using yaz_log(YLOG_WARN,..).
2103 Added CCL utility to remove terms (stop words) from resulting RPN
2104 tree. This is handled by functions with prefix ccl_stop_words_ .
2106 New ZOOM C option, "rpnCharset", which allows client-side conversion of
2107 terms in RPN queries.
2109 Clean-up the CCL API. Moved some internal structures from ccl.h to
2110 private header cclp.h. Changed ccl_parser_create so that a Bibset must
2111 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
2112 This is replaced by ccl_parser_find_str which takes a string instead.
2114 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
2115 libyaz.la is the core of YAZ except the generic frontend server and
2116 does not depend on POSIX threads anymore. libyaz_server.la is the
2117 generic frontend server facilities and uses POSIX thread functionality
2118 if available. The libyaz.la no longer depends on POSIX threads because
2119 the number of global structures is limited. NMEM no longer re-uses blocks
2120 between threads ; it simply free's memory immediately but allocates in
2121 "large" chunks as usual. We don't expect any performance penalties
2122 because of this. The yaz_log system is still using a global log_level so
2123 caution must be taken when modifying it with yaz_log_init_.. +
2124 yaz_log_mask_str. This, however, should not cause any trouble because
2125 these functions are called during initialization of application code
2126 anyway. `yaz-config --libs server` returns libs for server applications;
2127 `yaz-config --libs` returns libs for non-server applications.
2129 New OID database - with public definitions in oid_db.h. Removed old OID
2130 database including the head oid.h and definitions such as enum oid_value
2131 and struct oident. The new OID database uses the same string names as
2132 before but the 'protocol' is gone. There are now only two representations
2133 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
2134 converts from string to OID; functions with prefix yaz_oid_to_string
2135 converts the other way.
2137 Change to emit_term() in CQL-to-PQF query translation: when a term has
2138 the /regexp relation modifier, do not process it for leading and
2139 trailing "^" and "*", which have quite different meanings in regular
2142 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2143 write handlers no longer carries a 'last' parameter. This will make
2144 yaz_iconv flush "less" characters. A flush is performed by call to
2145 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2147 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2148 removed, because function yaz_query_to_wrbuf does the same.
2150 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2151 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2153 Deprecated MARC utility functions removed.
2155 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2158 Branch split: YAZ_2_1_55_branch
2160 --- 2.1.54 2007/03/16
2162 Fix to ZOOM-C so that transparent reconnection is properly handled on
2163 connections that are in asynchronous mode.
2165 Fixed compilation on OpenBSD 4.0.
2167 Large strings in GRS-1 records are now properly displayed in yaz-client.
2169 Added character conversion support for "advancegreek"; based on patch from
2172 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2173 sequence is met. Before the error was not set so it would be unknown.
2175 Adjust yaz-marcdump MARC reader so that it skips until record separator
2178 --- 2.1.52 2007/03/07
2180 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2181 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2182 fd_set structure used as a bitmask for the FDs to be selected on.
2184 Using ACX_PTHREAD macro to check for POSIX threads.
2186 Fixed have-vsnprintf check.
2188 --- 2.1.50 2007/02/23
2190 Fixes for configure on BSD. Bug #900.
2192 Added snprintf/vsnprintf wrappers for systems that don't have
2193 limits (heavens forbid).
2195 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2196 created before all previous tasks were completed and removed from the
2197 task queue, the new task could be removed by a mistake.
2199 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2201 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2203 Fixed bug #832: Problem with MARC/charset in yaz-client.
2205 Fixed bug #668: save command line history for yaz-client.
2207 Fixed bug #830: pkg-config support.
2209 --- 2.1.48 2007/01/23
2211 Extended ZOOM result set options with two options that may be read by
2212 a client: resultSetStatus and presentStatus with values as specified for
2214 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2216 Fixed bug #827: Using SSL fails on Debian etch.
2218 Fixed bug #826: Weird looking chars for set of MARC records.
2220 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2221 that is treated as an ItemOrder with itemRequest being an XML document
2222 external. The value of "doc" is the content.
2224 Extended the GFS search facility. New member of bend_search_rr
2225 'estimated_hit_count' signals that hits is known to be an estmate
2226 (higher or lower than real hit count). New member 'partial_resultset'
2227 signals that the search was partial (hit count is lower or equal than
2228 real hit count). For Z39.50, the information is stored in resultSetStatus
2229 member of SearchResponse APDU. For SRU, the information is signalled
2230 via SRU diagnostic 59: "Result set created with valid partial results
2233 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2235 --- 2.1.46 2007/01/13
2237 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2239 Added ZOOM_connection_peek_event.
2241 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2242 the following new functions:
2243 ZOOM_event_nonblock, ZOOM_connection_process,
2244 ZOOM_connection_get_{socket,mask,timeout},
2245 ZOOM_connection_fire_event_{timeout,socket}.
2246 The existing blocking event handler, ZOOM_event, is a wrapper for the
2247 + blocking ZOOM_event_sys_{poll,select}.
2249 Implemented function ccl_xml_config which parses XML version of CCL
2250 configuration (bug #798).
2252 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2254 Added timings utility (yaz/timing.h)
2256 --- 2.1.44 2007/01/03
2258 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2261 Fixed bug #779: Rotation of apdu.log fails.
2263 Fixed for character set conversions:
2264 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2265 Honor G1 set in MARC-8 decoding.
2267 --- 2.1.42 2006/12/17
2269 Fixed bug #775: char conversion does not handle Alternative UTF-8
2272 Implemented function yaz_marc_read_line which parses MARC line format
2273 records. There is a wealth of formats out there. So far, this function
2274 reads line records produced by yaz_marc_write_line.
2276 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2277 more generic and easier to remember(!) options: -i format and -o format
2278 which specifies input format and output format respectively - where
2279 format is one of "marc", "marcxml", "line", "marcxchange".
2281 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2282 does not print anything except warnings for records.
2284 For yaz-marcdump, added support for MARC split into files (-s) with a given
2287 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2288 spec, at http://www.loc.gov/standards/sru/record-update/
2289 This has changed the binary layout of the following structs:
2290 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2291 bend_update_rr . Patch by Ko van der Sloot.
2293 Added GFS utility function bend_assoc_is_alive which returns 1 if
2294 association is still alive (client is connected); 0 otherwise (client
2295 closed connection). This allows busy servers to stop working for
2298 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2299 been a separate piece of software. This version of ziffy has been modified
2300 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2302 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2304 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2305 Client code may now interrogate options such as "init_opt_sort" to
2306 find out whether the server claims to support various options.
2308 --- 2.1.40 2006/11/27
2310 Added utilities yaz_{set,get}_esn to set/get element set name from
2313 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2314 of YAZ and has been so since YAZ 2.1.10.
2316 Implemented ZOOM_record_error which returns error information for
2317 record (surrogate diagnostic).
2319 --- 2.1.38 2006/10/31
2321 Updates for SRU Update by Ko van der Sloot:
2322 1. Changed name from "operation" to "action"
2323 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2324 versions in the code, marked as 'backward compatible'.
2325 3. Added diagnostics for SRU Update.
2327 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2329 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2331 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2333 For GFS, fixed problem with SRU diagnostic 'First record position out of
2334 range' being issued for 0 hits.
2336 zoomtst10 part of Windows Build.
2338 --- 2.1.36 2006/10/13
2340 Implemented yaz_filepath_comp which splits a path into file path
2341 components (required by Zebra 2.0.3+).
2343 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2344 BSD inspired license until now so this should not have any real impact on
2345 anybody. See http://www.opensource.org/licenses/bsd-license.php
2347 Fixed bug #687: Missing log lines.
2349 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2352 Fixed bug #689: SRU diagnostics to be added.
2354 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2355 whether a connection is idle (no more work do do).
2357 --- 2.1.34 2006/10/04
2359 Change type of optval from long to int for invocation of setsockopt with
2360 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2362 Added support for specifying the max log file size for the Generic
2363 Frontend Server. The size is given with option -r.
2365 --- 2.1.32 2006/09/21
2367 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2369 --- 2.1.30 2006/09/17
2371 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2374 Fixed bug in Generic Frontend Server that could cause a server to stop
2375 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2377 For the generic frontend server, the maximum record size is used as maximum
2378 size of incoming packages (SRU + Z39.50). The value until was previously
2379 only used in Z39.50 Init negotiation and, later, in a session controlled
2380 sizes of records returned. This is controlled using -k option. It can be
2381 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2383 --- 2.1.28 2006/09/04
2385 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2388 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2390 New option for yaz-marcdump -lpos=value which allows setting a portion
2391 of MARC header to a certain value.
2393 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2395 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2396 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2398 --- 2.1.26 2006/08/15
2400 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2403 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2405 --- 2.1.24 2006/08/08
2407 Fixed MARC ISO2709 encoding routines to deal with character set
2410 Minor changes to GFS logging. Database included in search request log
2413 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2414 cached/multiple records.
2416 Shared libraries are built by default on Unix+configure.
2418 Changed cql2pqf transformation to use a different evaluation order. The
2419 new order is: always, relation, structure, position, truncation, index
2420 and relationModifier. Old order was: always, relation, relationModifier,
2421 structure, index, position, truncation. Note that the the latter ones
2422 override former ones for identical attributes.. The new scheme means that
2423 it is possible to override any existing attribute with a relationModifier.
2424 And also that it is possible to override everything for the index rule
2425 (except the ones listed in relationModifier). No order is perfect but this
2426 one, we believe, covers more real cases.. The "always" should have been
2427 called "default", since the attributes there can be overridden with all
2430 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2431 compilation phase, but also for yaz-config --cflags output. This allows
2432 us to have public headers with Libxml2 stuff in them . It should also,
2433 eventually, make Libxml2 checks redundant in packages using YAZ, such
2436 --- 2.1.22 2006/06/15
2438 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2439 stored in uri, message and details.. Previously diagnostics were stored
2440 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2441 compatibility.. but he's probably the only one affected, so.
2443 Added support for CCL, compiled on the client side, in ZOOM-C. This
2444 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2445 input; the resulting query objects can be used for for searching with
2446 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2448 YAZ' configure searches for OpenSSL by default.
2450 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2451 SL_CTX_use_certificate_file. See
2452 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2453 for more info. Thanks to Ko van der Sloot.
2455 --- 2.1.20 2006/06/02
2457 Bug #600: SRU GET, POST support for yaz-client. Introduced
2458 command 'sru' which selects method SOAP/GET/POST.
2460 Allow missingValueAction to be specified for the sortspec string -
2461 function yaz_sort_spec. By default, the missing value action is null.
2462 Use ! to specify "abort". Use = followed by stringvalue to specify default
2465 Ensured that Present-handler (if defined) is called in GFS before any call to
2466 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2467 searchRetrieve requests.
2469 Documentation for YAZ is now based on the Docbook XML/XSLT using
2470 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2471 is no longer depending on jade/openjade or docbook-to-man scripts.
2472 PDF is no longer part of the distribution - but can optionally be
2473 made using DSSSL/jadetex or FOP.
2475 Added retrieval handling support in Generic Frontend Server to support
2476 conversion between MARC/XML as well as XSLTtransforms. See
2477 etc/yazgfs.xml for an example.
2479 Added Authentication support to Generic Frontend Server in SRU
2480 mode. Authentication using HTTP Basic is supported, as is the use
2481 of 'x-username' and 'x-password' parameters in the request itself.
2483 Added support for a new character set MARC8s identical to MARC8 except
2484 that it converts combined characters to single Unicode characters in the
2485 Latin-1 range (when possible).
2487 --- 2.1.18 2006/04/24
2489 ASN.1 compiler 0.4: generates brief Doxygen file header for
2490 generated .h/.c files.
2492 Utility yaz_iconv now supports conversion to MARC-8.
2494 New facilities for the MARC module. The reading - and writing of
2495 content are separate methods for the yaz_marc_t handle. The following
2496 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2497 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2498 format). Write functions have prefix yaz_marc_write_.. The existing
2499 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2500 available. Removed support for OAI-MARC and simplexml (not the
2501 simplexml from PHP5).
2503 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2504 to be returned for this connection.
2506 --- 2.1.16 2006/03/31
2508 Allow multiple languages and charsets to be specified with
2509 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2510 negcharset iso-8859-1,utf-8
2512 Translation of proximity nodes from CQL into PQF now works.
2514 Moved to automake 1.8, 1.9.
2516 Added function yaz_log_set_handler which allows a log handler to be
2517 installed. This handler will be called for all log messages. Output
2518 to file is also produced; but that can be disabled by passing NULL
2519 fname to yaz_log_init_file.
2521 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2523 For SRW (including GFS), accept application/soap+xml as content-type
2526 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2527 produces NO stylesheet reference even if a default stylesheet is specified
2530 --- 2.1.14 2006/03/14
2532 Updated Windows package to include yazd.dll + yazd.lib for the
2533 Development component.
2535 If the environment variable YAZ_LOG is set, then it is used as a
2536 string indicating the default level of logging to use if not
2537 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2538 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2539 used as before. So, for example, to omit warnings from YAZ logging,
2540 export YAZ_LOG=-warn
2542 cql_transform() now map structure and other attributes before indexes,
2543 so that index-specific structures and other attributes can override
2544 defaults. So now a combination of mapping specifications such as:
2546 index.dc.date = 1=date-modified 4=5
2547 does the right thing.
2549 cql_transform() now also respects the "always" mapping specification,
2550 which establishes an initial set of attributes to be used for all
2551 terms except where overridden by more specific attributes associated
2552 with the index, relation or modifier.
2554 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2555 which mode to use; one of "post", "get" or "soap" (SRW, default).
2557 Fixes for yaz_iconv routines: changed trie-based character set conversions
2558 to use only non-negative values for bit fields due to Sun's C compiler not
2559 supporting negative values.
2561 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2562 sequences where not read correctly. Fix by Rustam Usmanov.
2564 Updated win/makefile to use options, settings which makes things
2565 compile with VS C 2005.
2567 --- 2.1.12 2006/02/01
2569 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2571 In ZOOM socket code, use select instead of poll on MacOSX.
2573 ZOOM-C now support client-side compilation of CQL into RPN that is
2574 sent to the server, enabling CQL to be used against all Z39.50
2575 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2576 ZOOM_query object, and submit it using ZOOM_connection_search().
2577 The CQL-to-RPN translation uses a configuration file, the name of
2578 which must be specified in the Connection's "cqlfile" option.
2580 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2581 function, which takes as its start-term parameter a ZOOM_query object
2582 (which may have had either CQL or RPN set into it).
2585 --- 2.1.10 2005/11/29
2587 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2588 GFS to support this as well. Backend handler, bend_srw_update, does the
2589 update work. Code contributed by Ko van der Sloot.
2591 Allow retrieval of Search Result-1 information in ZOOM by the use of
2592 options that are attached to a result set. ZOOM documentation updated
2595 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2596 UTF-8 conversion. Patch by Raj Patel.
2598 Added option -m to GFS to control formatting of timestamps in log file.
2600 Added 'exit' as synonym for 'quit' in yaz-client
2602 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2603 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2604 for the new members. Patch by Ko van der Sloot.
2606 Added support for SRU POST. It is supported for content-type
2607 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2609 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2610 Instead make the library libyaz.la multi-threaded. Threading as a whole
2611 can still be disabled by configure option --disable-threads. Previosly,
2612 with older GLIBCs there were problems with MT libs under Apache. This
2613 has now been fixed a long time ago.
2615 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2618 CQL module modified to be case insensitive for relations/indexes/operations.
2620 Fixed bug in CQL transform code: incorrect value relationModifieder
2623 Added 'show all' command for yaz-client which retrieves all results
2626 Added new yaz-client, xmles, which takes a (private) OID and
2627 a document to be sent as an extended service request.
2629 Describe new yaz-client commands wait_response and set_auto_wait.
2631 Increase TCP/IP listener backlog from 3 (which I am guessing was
2632 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2633 that the socket will queue as many incoming connections as it's able
2634 to handle ongoing connections. In other words, it will never now
2635 refuse a connection that it would be able to handle merely because
2636 it's not got around to accepting() enough of the pending connections
2637 yet. This is the behaviour anyway under Linux, where the listen()
2638 argument is ignored; but not under BSD and on systems such as
2639 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2640 YAZ-based servers should now be uniform across operating systems in
2643 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2644 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2645 This allows yaz-marcdump to read large MARC batches (>2 GB).
2647 Modified all YAZ source files - except the source which is auto-generated
2648 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2651 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2652 corresponding to the existing *_setl() function. These allow option
2653 values containing arbitrary valuues.
2655 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2656 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2657 except that it returns an indicator of whether or not the sort
2658 criterion was accepted (0 for OK, -1 for invalid).
2660 --- 2.1.8 2005/06/07
2662 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2663 MARC output rather than returning "new" buffer.
2665 yaz-client warns about unknown init options.
2667 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2669 --- 2.1.6 2005/05/24
2671 Added support for SRW sort in Generic Frontend Server. Patch
2672 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2673 sortKeys - or NULL if none is provided.
2675 Fixed bug #307: It was impossible to specify indefinite/no timeout
2676 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2679 Added support for multiple languages and charsets to be specified in
2680 ZOOM. Each charset/language is separated by a blank. If negotiation is
2681 in effect in init-response, Option
2682 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2683 Code based on patch by Vasiliy Osadchuk.
2685 Fixed bug #306: infinite recursion that occurred when calling
2686 yaz_log_level_init as the first call (before other log level or
2689 Fixed bug in scan handling in front end server: if preferred-Position-In-
2690 Response was non-present, a NULL pointer referece was performed.
2692 --- 2.1.4 2005/04/26
2694 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2695 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2696 now defined for all those error codes. So instead of putting 109 in
2697 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2698 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2700 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2703 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2705 Program yaz-client now exits and produces an error message if multiple
2706 Z39.50 servers are specified on the command line (none or one allowed
2709 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2712 --- 2.1.2 2005/03/16
2714 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2716 Fixed bug #272: Preserve spacing for CCL terms.
2718 --- 2.1.0 2005/03/14
2720 Added support for virtual hosts and multiple backend servers for
2721 the YAZ frontend server. The configution is XML based and
2722 support specificition of CQL to RPN mappings and explain information.
2723 See section "Virtual Hosts" in the YAZ manual.
2725 Extended OPAC display utility. OPAC display utility renders
2726 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2727 to supplement yaz_marc_decode_wrbuf.
2729 Fixed a bug in MARC decoder that could caused it to crash for some
2730 invalid MARC records. More diagnostics and warnings where added in
2731 XML output (warnings, etc are stored in comments).
2733 --- 2.0.34 2005/02/08
2735 Fixes for UNIX domain sockets. Bug #261.
2737 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2739 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2740 Added yaz_marc_subfield_str which defines subfield lead string which is
2741 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2742 yaz_marc_endline_str which defines end of fields string used in
2743 YAZ_MARC_LINE format. Default string is newline.
2745 Experimental support for MarcXChange. This format can be produced
2746 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2747 http://www.bs.dk/standards/MarcXchange.xsd
2749 Added yaz-client commands scansize that sets maximum number of
2750 entries to be returned by scan.
2752 --- 2.0.32 2005/01/11
2754 Added support for SRW scan in yaz-client and Generic Frontend Server.
2756 * Added whereInList member to SRW Scan Term.
2758 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2760 Fixed NMEM system to return aligned blocks on the smallest boundaries
2761 that are suitably aligned for all possible types on the particular
2762 architecture YAZ is being built for.
2764 --- 2.0.30 2005/01/04
2766 Fixed numerious warnings that was issued with newer versions of GCC.
2768 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2769 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2772 Make YAZ Generic Frontend Server slightly faster.
2774 Enhance (and reduce) logging for Generic Frontend Server.
2776 Revert YAZ log system so that it flushes every write operation
2777 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2779 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2780 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2781 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2782 will effectively disable old definitions.
2784 --- 2.0.28 2004/11/09
2786 Added yaz_log_time_format which specifies log format using
2789 Added yaz_log_module_level which returns mask for a module. Value
2790 is non-zero mask a if module is enabled; zero if disabled.
2792 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2793 in include/yaz/cql.h.
2795 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2797 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2799 Fixed bug #172: RPM builds does not enable SSL.
2801 Doxyfile.in part of dist. Doxyfile generated by configure.
2803 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2804 are given and the corresponding component does not exist.
2806 Extend CCL documentation in YAZ reference. Describe r=r.
2808 --- 2.0.26 2004/10/01
2810 Fixed MARC->MARCXML conversion to properly deal with
2811 fields, subfields, indicators having non-ASCII characters.
2813 Fixed MARC->MARCXML conversion so that ASCII control characters
2814 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2817 Added YAZ GFS support for conversion from Z39.50 surrogate
2818 diagnostics to SRW surrogate diagnostics.
2820 Bug fix: YAZ GFS did not return schema in explainResponse.
2822 --- 2.0.25 2004/09/30
2824 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2825 now converts recordSchema to elementSetName as well as schema URI.
2827 Fixed bug in COMSTACK that prevented HTTP request packages from being
2830 --- 2.0.24 2004/09/29
2832 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2833 does not require white-space before and after the dash in a range, e.g.
2834 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2837 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2838 due to new GCC removing "redundant" code.
2840 Added yaz-client commands scanpos and scanstep that sets preferred
2841 position and step-size for scan.
2843 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2845 Added CCL utility ccl_qual_buf which parses one or more CCL
2846 spec lines in a buffer.
2848 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2849 of name and value - ignoring empty lines and comments.
2851 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2853 Added odr_get_element_path which returns current element path for an
2854 ODR handle. This utility is useful in error handling or user-defined
2857 Added ODR_PRINT utility odr_set_stream which is is a more generic
2858 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2859 to a write function and pointer to close function. The close function - if
2860 non-NULL - will be called during odr_destroy.
2862 Fixed bug in CCL parser where truncation char was not removed from
2863 right side when truncation=both was in effect.
2865 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2868 --- 2.0.23 2004/08/11
2870 Fix buffer overrun in CQL parser when dealing with proximity (%).
2872 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2873 to UTF-8/UCS conversion is now only based on codetables.xml.
2875 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2877 --- 2.0.22 2004/08/06
2879 Add support for more "commit changes" in ZOOM (uses Extended Services).
2881 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2884 Yet another small fix for configure of SSL.
2886 --- 2.0.21 2004/05/14
2888 Fix SSL libs for configure when --with-openssl=DIR is given.
2890 --- 2.0.20 2004/05/10
2892 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2894 SSL comstack now uses yaz.pem certificate file on server side
2895 by default. Certificate filename can be configured by calling
2896 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2898 Fix bug regarding multiple calls to ZOOM_connection_connect.
2900 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2902 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2903 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2905 ZOOM now allows inspection of X509 peer certificate for verification.
2906 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2908 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2909 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2910 as "modular" but it simplifies things.
2912 Added cs_get_peer_certificate to that returns peer X509 PEM.
2914 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2915 NULL if SSL is unavailable.
2917 Documentation about MARC decoding tools.
2919 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2921 --- 2.0.19 2004/03/30
2923 Rename CHANGELOG to NEWS to follow GNU style packing.
2925 Fix bug with missing initialization of member in init_diagnostics.
2926 This bug affects threaded version of GFS server.
2928 --- 2.0.18 2004/03/20
2930 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2933 Ensure zlib.dll is packed with Windows install.
2935 --- 2.0.17 2004/03/17
2937 Fix encoding of xsd:string to use text instead of CDATA.
2939 Fix endless loop in CQL parser with unbalanced ".
2941 Use a more compact way to store MARC-8 conversion tables.
2943 --- 2.0.16 2004/03/16 Debian only
2945 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2948 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2953 --- 2.0.15 2004/03/01
2955 Another fix for decoding of XML packed records.
2957 --- 2.0.14 2004/02/25
2959 Fixes for Chunked encoding. White space not ignored after length spec.
2961 Update NS and use default NS for SRW diagnostic elements.
2963 --- 2.0.13 2004/02/23
2965 Implement ZOOM_resultset_cache_reset which resets record cache.
2967 Implement ZOOM_resultset_sort which sorts a result set.
2969 Implement chunked HTTP transfer.
2971 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2973 --- 2.0.12 2004/02/16
2975 Added member 'schema' to bend_explain_rr structure so that backend
2976 can specify explain record identifier. Defaults to Zeerex 2.0.
2978 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2980 --- 2.0.11 2004/02/16
2982 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2985 Added init command for yaz-client which sends "extra" init request.
2987 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2988 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2990 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2992 Make ZOOM error code for "invalid query".
2994 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2996 --- 2.0.10 2004/02/05
2998 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
3001 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
3003 Added option -p <file> to make Generic Frontend Server to write PID file.
3005 Added option -D to put Generic Frontend Server in background on its own.
3007 Make ZOOM C recognize option "password". If unset, "pass" is used
3008 (for backwards compatibility).
3010 Fixed a bug in Generic Frontend Server that could make it crash if a
3011 client sets characterSetNegotation bit, but didn't pass negotiation stuff
3014 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
3015 Must be issued before open, in order to be in effect.
3017 --- 2.0.9-6 2004/01/12 Debian/Windows
3019 Make the SRU server more picky WRT unknown params, etc.
3021 Bug fix: ZOOM scan response didn't return displayTerm - when present.
3023 New YAZ client command, options, that sets Z39.50 options.
3025 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
3026 options from a string of tokens (one token for each option bit).
3028 Update SRW diagnostic code messages.
3030 --- 2.0.9-5 2004/01/07 Debian/Windows
3032 Handle user defined stylesheet for SRW/SRU.
3034 --- 2.0.9-4 2004/01/06 Debian/Windows
3036 Fix bug in decoding of Content-Length.
3038 --- 2.0.9-3 2004/01/06 Debian/Windows
3040 Fix a bug with decoding of XML packed records.
3042 --- 2.0.9-2 2004/01/05 Debian only
3044 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
3046 Fix bug in SRW/SRU diagnostics decoding.
3048 --- 2.0.9 2004/01/05
3050 Fixed bug in Generic Frontend Server which could drop records exceeding
3051 preferred message size. Reported and fixed by Irina Dijour.
3053 Fixed calculation of package size for structured records in Generic
3054 Frontend Server. Reported and fixed by Irina Dijour.
3056 Fixed namespace for SRW/SRU diagnostics.
3058 Fixed SEGV in yaz-client that occured for HTTP connection errors.
3060 --- 2.0.8 2003/12/22
3062 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
3063 this version is incompatible with version 1.0 and older YAZ SRW/SRU
3066 CQL changes to reflect recent changes to the specification:
3067 * Documentation talks about context sets instead of index sets.
3068 * Documentation talks about indexes instead of qualifiers.
3069 * The CQL-to-PQF transformer's configuration file now uses
3070 "index.set.name = <attributes>" instead of the old form
3071 "qualifier.set.name = <attributes>". (Both forms are still
3072 understood but the latter is deprecated.)
3073 * CQL terms with no explicit index specified are now interpreted as
3074 cql.serverChoice instead of srw.serverChoice (which of course
3075 behaves exactly the same.)
3077 --- 2.0.7 2003/12/16
3079 MARC conversion can now generate ISO2709 output in another
3080 character set. yaz-marcdump uses this facility if you invoke it
3083 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
3084 functions from there can be used from C++.
3086 --- 2.0.6 2003/12/04
3088 Frontend server now transfers memory from decoded packages to stream
3091 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
3092 references to show up.
3094 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
3095 the ZOOM Abstract API. The older names for the same options are still
3096 also supported for the benefit of old applications.
3098 ZOOM-C supports "implementationId" and "implementationVersion" options
3099 to go along with "implementationName". These allow the user code to
3100 specify identification strings to be sent to servers.
3101 Add OID for the new ExtLite attribute set.
3103 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
3104 as requested/supplid by Ere Maijala <ere@atp.fi>
3106 For generic frontend server, reverse the order of
3107 "toolkit-supplied / application-supplied" strings sent as implementationId,
3108 Name and Version. Also, remove the spaces around the slash. This brings
3109 the GFS in line with the behaviour of ZOOM-C on the client side.
3111 Add function ZOOM_scanset_display_term.
3113 yaz-client shows scan displayTerm if present.
3115 Utility yaz-iconv is now installed by default along with the man page
3118 Extend configure check for OpenSSL to use pkg-config where available (such
3121 Incorporate patch by Morten Bogeskov which allows a Unix file socket
3122 server to specify uid/gid/mask for socket using the format
3123 unix:[user=uid,][group=gid,][umask=mask,]file=path
3124 If file= is omitted the existing format is assumed, e.g.
3126 in which case the mask is 0666 (rw for everybody).
3128 Major restructure of YAZ source. All source in libyaz is in src directory.
3129 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
3130 util (utility programs such as ASN.1 compiler, yaz-marcdump).
3132 Added man page for utility yaz-marcdump (used to be called marcdump).
3133 yaz-marcdump is installed by 'make install'.
3135 Fixed a memory leak in Generic Frontend Server that occurred when decoding
3136 of incoming package failed.
3138 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
3140 Change prototype of odr_perror: add const to message string.
3142 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
3144 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
3145 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3146 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3147 DNS lookup. There should not be any compatibility problems with this
3148 assuming that blocking=1 or 0 is used.
3150 Fix bad reference in UNIX comstack in function cs_addrstr.
3152 Fix for compilation on AIX.
3154 The generic front-end server (server/seshigh.c) now supports returning
3155 Init diagnostics to the client in User-information-field, in
3156 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3159 --- 2.0.4 2003/09/04
3161 Allow any CQL relation (not just all,any,exact,scr).
3163 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3164 that features the same UI.
3166 Implemented command update0 in YAZ client which is equivalent to
3167 update but uses old of Ext Update ASN.1.
3169 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3170 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3171 Previously no OID was used for this info.
3173 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3174 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3175 returns 'malformed search term' otherwise.
3177 SortResponse member resultCount now set to NULL in sort handler of
3180 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3183 Add three new utility functions for translating OIDs between various
3184 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3185 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3186 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3187 char *oid_to_dotstring(const int *oid, char *oidbuf);
3188 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3190 Reverted modifications for ES Update definition for z_IU0Update
3191 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3192 is back to YAZ 2.0.2.
3194 String value attributes for CCL parser.
3196 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3197 which their FirstSearch server returns in Init responses, sometimes
3198 carrying useful diagnostic information when Init fails. This has the
3199 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3200 "z39.50/oclcui.asn", where its definition is somewhat different from
3201 what OCLC document on their web-site, as required to interoperate with
3204 Support for anonymous authentication in yaz-client. Use the command
3207 * Fix the OID of the Index Data-local "admin" Extended Service from
3208 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3209 the 1000, which indicates a locally-defined OID, was a mistake.
3211 --- 2.0.3 2003/06/20
3213 Fix CCL directive @case handling so that it affects string match for
3214 both CCL keywords and qualifiers.
3216 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3217 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3218 Decoder has been updated with ASN.1 changes as listed in
3219 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3220 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3221 z_IUUpdate, remains unchanged.
3223 ZOOM_record_get may now return a record in a specific character set.
3224 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3225 "from" is the character set of record as returned by target. "to" is
3226 the character set to be returned. If omitted, "to" is UTF-8.
3228 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3230 New ODR utility, odr_getelement, which returns name of element for
3231 which encoding/decoding failed.
3233 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3234 in cases where a required element was omitted.
3236 Bug fix: some MARC8 sequences were not converted.
3238 New ZOOM option "step" which specifies number of records to be
3239 retrieved in one chunk. Used in conjunction with "start" and "count".
3241 SRW support for yaz-client. Use scheme http: to use it, e.g.
3244 yaz-client no longer does (un)intelligent character set conversions
3245 by default. Can be enabled with charset and marc_charset commands.
3247 xmalloc trace fix for 64-bit systems such as DEC alpha.
3249 Solaris 2.6 compile fix.
3251 New function, cql_strerror() translates SRW error codes, as returned
3252 by cql_transform_error(), into human-readable English strings. Used
3253 in yaz-client diagnostics when appropriate.
3255 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3256 converts it into a type-1 query which is sent to the server. This
3257 makes CQL available for use with all Z-servers, as opposed to the tiny
3258 minority that can handle CQL queries themselves.
3260 --- 2.0.2 2003/04/28
3262 New Debian package layout similar to the Redhat Package layout.
3264 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3265 and search result respectively.
3267 --- 2.0.1 2003/04/25
3269 Redhat package is now several packages: libyaz (runtime libraries),
3270 libyaz-devel (development and documentation, and yaz (utility programs).
3271 Package spec file by Morten Bogeskov.
3273 New member 'schema' in struct bend_fetch_rr which the name of requested
3274 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3275 handler MAY set this to reflect the schema of the returned record.
3277 New member 'display_term' in struct scan_entry. GFS now sets member entries
3278 and allocates scan entries to be filled by user scan handler. In previous
3279 version, entries member was allocated by the scan handler. That still works,
3280 but the GFS will ignore member display_term - assuming it was NOT set by
3281 the handler. The fact that the GFS now allocates the entries both allows
3282 for new members and makes a scan handler easier to write.
3284 Fix CQL lex buffer overflow.
3286 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3287 SRU default recordPacking is string.
3289 SRU protocol support for frontend server.
3291 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3293 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3295 Added scan for the ZOOM shell (zoomsh).
3299 * String Identifers for Schemas (Amendment 5).
3300 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3301 Old definition for schema
3302 Odr_oid *schema; /* OPT */
3307 Z_InternationalString *uri;
3308 #define Z_Schema_oid 1
3309 #define Z_Schema_uri 2
3312 * resultCount parameter to Sort Response (Amendment 1).
3313 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3315 Support for SRW 1.0 over HTTP. This is an optional feature and
3316 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3319 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3320 on the same port. SRW SearchRetrieveRequests are mapped
3321 to bend_init,bend_search,bend_fetch,bend_close.
3323 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3325 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3326 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3328 ZOOM connections are SRW based if schem http is used for hostname
3329 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3330 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3332 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3333 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3334 distance=n, order=true/false, relation=le, prox unit=word. If
3335 n is omitted, distance 1 is used.
3337 Fixed problem with C compiler include path in wrong order.
3339 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3340 on Solaris. Patch from Ko van der Sloot.
3342 New MARC decode API. All new functions operate on a yaz_marc_t
3343 handle. The most important new functions are: yaz_marc_create,
3344 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3345 decode and destroy respectively. Decoder can produce formats
3346 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3347 include/yaz/marcdisp.h.
3349 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3350 to UTF-8, UCS-32, wchar_t or Latin-1.
3352 * Prototypes for yaz_iconv_-functions moved to separate header
3353 include/yaz/yaz-iconv.h.
3355 Make a few private functions 'static' in unix.c. This prevents
3356 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3358 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3359 are set when Init Response is received.
3361 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3362 but returns diagnostic set as well.
3364 New function yaz_strerror which is a portable wrapper for
3365 strerror/strerror_r/GetLastMessage.
3367 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3368 is returned for MARC. If type is "oai", then OAI MARC is returned.
3370 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3373 --- 1.9.2 2002/11/26
3375 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3377 Fix bad race conditions on SIGTERM and terminate gracefully in
3380 Move retrieval (data1) module to Zebra since nobody seems to be
3383 Add GRS-1 render for ZOOM using same format as yaz-client.
3385 --- 1.9.1 2002/10/05
3387 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3389 Fix broken ESpec handling in data1 module.
3391 SGML reader parses comments and makes them part of the data1 tree.
3393 Added several type casts so that YAZ compiles as C++ code.
3395 ZOOM didn't handle PDU encoding failures properly.
3397 Added more Bib-1 diagnostics (approved extensions).
3399 GNU configure: better check for iconv.
3401 More portable use of accept, getpeername. Check for socklen_t. Use
3402 int/size_t if socklen_t is not defined.
3406 PQF parser rejects bad queries - including those with extra
3407 characters in them. PQF parser used to silently ignore that.
3408 Cleaner API for PQF added, which allows you to get detailed
3409 error information for bad queries (see yaz/pquery.h).
3411 Fixed bug in ZOOM_record_get for type "database".
3413 Implemented mini iconv library supporting conversions between
3414 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3416 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3418 --- 1.8.9 2002/08/20
3420 Fixed ZOOM C record cache so that preferredRecordSyntax and
3421 elementSetName is used to check for already fetched records.
3423 --- 1.8.8 2002/08/02
3425 Added three members in bend_initrequest structure to facilitate
3426 character set negotiation.
3428 Fixed a bug in frontend server that could cause indefinite
3429 loops under rare conditions.
3431 Revised character set utilities (charneg.h) so that encoding
3432 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3434 For PQF, directive @term <type> sets term type for Scan/Search.
3435 Here <type> is general, string, numeric, null. The term type
3436 is inherited - just like @attr.
3438 New call odr_set_charset that sets character set conversion for
3439 international-strings on a ODR stream. Prototype is:
3440 int odr_set_charset(ODR o, const char *to, const char *from);
3441 The InternationalString is still represented as C string in YAZ
3442 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3443 won't). On the protocol level, you can use any encoding.
3445 Support for UNIX sockets in ZOOM.
3447 Solaris recv sometimes returns errno == ENOENT. It is treated as
3448 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3450 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3451 both client and server. Code by Morten Bogeskov.
3453 --- 1.8.7 2002/05/22
3455 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3456 that they can be used directly from Visual Basic. You must recompile
3457 your windows APP if you're using ZOOM.
3459 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3460 Commands "lang" and "charset" sets language and character set respectively.
3461 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3462 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3464 Attributes from multiple CCL fields may be OR'ed rather than merged
3465 using directive "@field or". Fields are still merged by default -
3466 equivalent to "@field merge".
3468 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3471 Fixed bug in zget for parameter ExtendedServicesResponse.
3475 --- 1.8.6 2002/03/25
3477 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3479 Client displays USR.1:SearchResult-1 (hits per term).
3481 Additional Search Info for search in Generic Frontend Server.
3483 Fixed CCL parsing of "field=s".
3485 WIN32 installer - using the excellent NSIS software from nullsoft.
3487 Fixed CCL parsing of "field = - <number>".
3489 Added function yaz_marc_decode that decodes MARC for line mode
3490 display or XML (similar to that used by JZKit).
3492 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3493 Z39.50. But ISO/ILL was, however.
3495 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3496 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3498 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3499 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3501 --- 1.8.5 2002/02/03
3503 New YAZ client features: Command completion and new commands:
3504 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3505 Code provided by Jacob Poulsen.
3507 New call oid_trav, that visits all registered OIDs via callback.
3509 Function ZOOM_record_get now returns const char pointer rather than
3510 void pointer. It saves a lot of type casts.
3512 For YAZ client, command "auth" now allows you to set authentication
3513 in IdPass style. It is enabled when three tokens are given - order
3514 is user, group and password.
3516 Fix memory leaks in MARC record handling for ZOOM.
3518 New option for YAZ client, -k <kilobytes> that sets
3519 maximum record size. Similar to -k option for generic frontend
3520 server and yaz-ztest.
3522 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3524 Prefix query parser reports "fail" when bad attribute set is given.
3526 Fix in MARC decoder. Proximity logging. Fix for attribute set
3527 in scan handler for server. Patches by Shigeru Ishida.
3529 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3532 Configure option --with-openssl=<dir> now works when a directory is
3533 specified. Patch provided by Morten Bogeskov.
3535 New option for YAZ client, -u <auth>, that sets authentication.
3537 ZOOM fix: error information was sometimes "missing", since error
3538 was cleared/reset too when it shouldn't.
3540 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3542 --- 1.8.4 2002/01/04
3544 Scan for ZOOM API. New object ZOOM_scanset. New functions
3545 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3546 ZOOM_scanset_destroy.
3548 New ZOOM function, ZOOM_connection_last_event, that returns type
3549 of last event (such as "receive data", "send data", "apdu received",
3552 New ZOOM option, schema, that specifies schema for retrieval.
3554 New CCL feature. Qualifiers can be aliases for one or more
3555 other qualifiers (if more than one is given, OR is used).
3557 ZOOM uses named result sets if target supports it.
3559 Two new YAZ client commands: . (dot, which sources a script of YAZ
3560 client commands), and ! (to execute shell command.). Implemented
3563 Working on Debian packages.
3565 --- 1.8.3 2001/11/19
3567 YAZ client enables named result sets only if target supports it.
3569 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3571 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3572 with key="host" to get same result.
3574 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3575 Function Z3950_resultset_record(s) returns references to records
3576 "owned" by resultset. To become owner use Z3950_record_clone.
3578 Function z_ext_record handles Extended Services. Thanks to
3581 --- 1.8.2 2001/11/12
3583 CCL Parser fix: ignore token comma when dealing with and-lists.
3585 Documentation updates for COMSTACK.
3587 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3588 Changed prototype Z3950_records. For some functions, int parameters
3589 were changed to size_t.
3591 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3594 New MARC decode/display function, marc_display_exl, which properly rejects
3595 non-ISO2709 records. YAZ client uses it.
3597 --- 1.8.1 2001/10/29
3599 Fix bug: local attribute set wasn't set correctly in PQF strings.
3603 * Old Z39.50 codecs no longer supported.
3605 Added ZOOM C binding. See http://zoom.z3950.org/
3607 Renamed states for COMSTACKs to avoid confusion with events.
3609 Implemented cs_look and proper cs_rcvconnect.
3611 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3613 Configure detects POSIX threads on OpenBSD.
3615 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3616 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3618 When error is returned from present handler, non-surrogate diagnostic
3619 is returned in present response (and fetch handler is no longer called).
3621 * Minor adjustments to pquery parser (PQF). Token characters may be
3622 escaped by using backslash (C-style).
3624 PQF parser allows string attribute values to be specified. For @attr,
3625 non-numeric characters after the equal-sign are treated as strings
3626 (e.g. @attr 9=title).
3628 CCL trunction character may be defined (@truncation in file)
3630 * function zget_ExtendedServicesRequest sets waitAction to
3631 waitIfPossible (was wait).
3633 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3636 CCL operator names may be set in field definition files (CCL_bibset).
3637 See ccl/bib1 for an example.
3639 Fixes in ASN.1 compiler for C++ compatibility.
3641 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3642 and "op_or" to avoid conflict with C++.
3644 Fixed problem with GNU readline detection on Redhat 7.0.
3646 Added step-size for Scan backend handler.
3648 Fixed bug that made the frontend server crash when no attribute
3649 set was specified for scan.
3651 Front-end server automatically switches to original working directory
3652 when installed as an NT service. Previously -w had to be specified to
3655 Added extended attributes for retrieval module (data1), so that data1
3656 records carry d1_readXML/SGML attributes. d1_read also supports
3657 null-data rules ( <tag/>)
3659 On UNIX when POSIX threads are available, a separate library libyazthread
3660 is created. Programmers should link with that library and the yaz library
3661 when using threads. The reason for the split was that some applications
3662 on Linux, such as Apache, doesn't work well when using shared objects that
3665 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3666 (or any frontend server) in SSL mode by specifying ssl: followed by
3667 address. Only tested on UNIX.
3669 Added feature for CCL module. Virtual structure s=al or s=ol generates
3670 and-list and or-list respectively instead of phrase search.
3674 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3675 log_mask_str. This was done to avoid name conflicts with other libraries
3676 (such as other PHP extensions).
3678 Added raw OID member for preferred record syntax (request_format_raw)
3679 and returned record syntax (output_format_raw) for backend fetch method.
3681 Config file yaz-config now accepts options so that it returns specific
3682 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3684 Shared library support for UNIX using GNU libtool.
3686 * Modified backend interface. Request/Response struct's replaced by
3687 one read/write C struct. For example bend_fetchrequest and
3688 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3689 Every handler - even search has to be registered in bend_init
3690 handler. This means that the YAZ library no longer refers to
3691 external functions and it makes it possible to make the whole
3692 thing a single DLL/SO.
3694 Added Segment handler for backend server.
3696 Added Zmbol/Zebra administrative functions to YAZ client.
3698 Threaded frontend server on UNIX (when POSIX Threads are available).
3699 Starting the server with option -T enables multi-threading.
3703 Added configure option --enable-comp/disable-comp to control use
3704 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3705 located in sub directory asn.
3707 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3708 in ${exec_prefix}/bin along with the other programs yaz-client and
3711 GNU automake used to maintain makefiles.
3713 Added several OID's.
3715 Changed retrieval module so that we can load records with no abstract
3716 syntax defined. Tagpaths in these records are fully composed of string
3719 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3723 On UNIX, the generated makefile now supports a proper 'make install'.
3724 The prefix can be set via GNU configure to set the install location
3725 (default is /usr/local).
3727 * YAZ programs client and ztest were renamed to yaz-client and
3728 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3729 locations, such as /usr/bin,/usr/local/bin,etc.
3731 * YAZ Header files were moved from include to include/yaz. YAZ Header
3732 files are referred to as include <yaz/log.h> rather than <log.h>.
3733 The YAZ include path (-I ..) is therefore the same as before. Programmers
3734 should update their #include statements or use -Ipath/include/yaz
3735 instead. The main motivation for doing this change is that YAZ header files
3736 can be installed in "standard" locations /usr/include,/usr/local/include
3737 without introducing conflicts, since ALL YAZ header files are stored
3738 in subdirectory yaz (under /usr/include for example).
3740 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3741 rather than project/workspace files. We switched because project files
3742 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3745 Changed name of logging function, logf, to yaz_log, to prevent name
3746 clash with some math-log functions. The YAZ header log.h defines logf
3747 to yaz_log (#define) so there should be no incompatibilities by this
3750 Added bend_start/bend_stop handlers for server. These handler are
3751 called on start/stop of server. For windows they are called whenever
3752 a service is started/stopped.
3754 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3755 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3756 in util/yc.tcl. The auto-generated C code structures are, in a few
3757 cases, incompatible with the old decoders. There are differences in the
3758 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3759 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3760 The preprocessor variable ASN_COMPILED is defined when the compiled
3761 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3762 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3763 wish to use the old encoders/decoders you can specify --disable-yc
3766 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3767 version so that it supports both new - and old version of DB Update
3769 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3770 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3771 change. The name parameter can be set to 0 in which no name is specified
3772 for the construction. The macros odr_implicit and odr_explicit sets name
3773 parameter to zero for the construction involved. New macros
3774 odr_implicit_tag and odr_explicit_tag are similar to the others,
3775 except that a name parameter is added. For programmers' that don't use
3776 ODR they probably only need to change the call to z_APDU and z_External.
3778 Added access control facility by interfacing the TCP wrapper library.
3779 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3780 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3781 name of the daemon and enables the access control as specified in
3782 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3784 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3785 den Dool <H.M.vdnDool@kub.nl>.
3787 Added reference ID parameter to most functions in server API - refer
3788 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3790 Changed name of ccl library to libccl.a (was ccl.a).
3792 Fixed bug in decoder for Explain (Category TargetInfo).
3794 Added support for GNU readline in client. Thanks to Jacob Poulsen
3795 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3797 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3798 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3799 IMPLEMENTATION! This change was made to the development version before
3800 the ZIG decided to retract the amendment. If any users MUST be
3801 compatible with the original Update definition, PLEASE CONTACT US, and
3802 we will include a separate definition corresponding to the old Update
3803 ES. Note that because of the change to the ASN.1 of the
3804 TaskPackageRecordStructure we cannot define a single structure that
3805 will support both versions.
3807 * Added const modifier to buffer parameter for some ODR/BER encoding
3808 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3809 completeWAIS, odr_dumpBER.
3811 Fixed bug in client.c which caused a crash when a scanResponse didn't
3812 contain positionOfTerm.
3814 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3815 * will cause an error in a client if a non-YAZ target sends both a
3816 * list of Scan entries and non-surrogate diagnostics.
3818 Retrieval module enhancements. Tag sets may be typed in the reference
3819 to it. From the .abs-file the "tagset" directive takes a third optional
3820 integer type for the tag set referenced. From a .tag-file the "include"
3821 directive takes a third optional type as well. The old "type" directive
3822 in the tag set itself is still recognized but acts as the default type
3825 Backend interface change. Individual Scan terms returned from bend_scan
3826 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3827 in include/backend.h.
3829 Retrieval module enhancements. Multiple tag sets and attribute sets may
3830 be specified in abstract syntax specs. Revised the error/warning for
3831 logging messages reported by the retrieval module when reading the
3834 Object Identifier system (oid_..) changed. The API is backwards
3835 compatible but the oid-routines now allocates new OID's when needed.
3836 Raw OID's may be specified in oid_getvalbyname.
3838 YAZ now uses GNU configure to generate Makefile(s).
3840 * Minor changes in some of the member names of DeleteResultSetRequest and
3841 DeleteResultSetResponse. See include/proto.h.
3843 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3844 and added member 'languages' in TargetInfo (which was missing).
3846 Changed the way attribute sets are handled in the retrieval
3847 module. These are now cached, just like the abstract syntaxes
3850 Changed YAZ so that it links with compiled ASN.1.
3852 Added Explain-schema definitions and mapping routines. The following
3853 Explain categories have been implemented: AttributeDetails,
3854 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3856 Fixed minor bug in Windows version of Server Library.
3858 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3860 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3862 Added EXTERNAL: UNIverse Resource Report (non-standard).
3864 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3865 ENUMERATED and SET OF.
3867 * Added 'const' to some of the char pointer arguments for the
3868 functions, data1_read_node, data1_getelementbytagname,
3869 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3872 Fixed bug in data1_insert_taggeddata - the last_child member of
3873 parent wasn't initialised.
3875 * Changed data1_read_record and data1_read_node so that the supplied
3876 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3877 doesn't refer to any parts of the "SGML"-buffer.
3879 Fixed bug in server library (Windows version of statserv_remove).
3881 * Changed code so that it compiles as C++. The type definition
3882 of Odr_fun which is a member of Odr_arm was changed. The result is,
3883 that an explicit typecast is needed for the fun pointer when
3884 using Odr_arm - as in:
3885 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3887 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3889 Implemented the new structured date and time definition as approved
3890 by the ZIG. Added schemaId element to the specificTag in Espec-1
3891 (also approved at the last ZIG). Thanks to RVDM.
3893 Added some Object identifiers (RVDM).
3895 Changed the Update Extended Service (RVDM).
3897 Added command "refid" to client which specifies referenceId for
3898 the following requests.
3900 Implemented extended service handling for server. See ztest.c
3901 for an example as well as backend.h. New handlers are registerd
3902 in the Init handler.
3904 * Changed interface for sort in server.
3906 Added new members to statserv_options_block. It allows a server
3907 to read options from another source than just the command line. Thanks
3908 to Charles Woodfield.
3910 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3911 renamed to zboolean. Some C++ compilers complained about the name.
3913 Minor changes to gils.abs. Added index 's' (sort) on title
3914 and date/time-last-modified.
3916 --- 1.4pl2 1998/1/30
3918 Fixed bug in server library regarding inetd mode (-i). This bug
3919 was introduced by release 1.4.
3921 --- 1.4pl1 1998/1/29
3923 Added sort facility in client and backend server interface.
3925 Fixed problem with dependencies in Makefile(s).
3927 Fixed bugs for encoders/decoders of extended services and
3930 Implemented sub-tree feature for schemas. Sub-trees are
3931 referenced in *.abs-files. See explain.abs for an example
3932 of the use of this feature.
3934 Modified bib1.att; local attributes for ANY didn't include
3935 ANY itself (only affects use of the retrieval module).
3937 Fixed bug in plain SGML reader in function data1_read_node:
3938 tags with prefix "var" was incorrectly interpreted as variants.
3940 Added feature "sub-schemas" to enable references to - and definitions
3941 of - group of elements.
3943 * Removed member parent from type data1_element (in data1.h).
3945 Implemented function odr_nullval() that returns the value of
3948 * Removed member num_children from data1_node (in data1.h).
3950 Made NT service interface part of the server library. The
3951 function statserv_main uses the NT service when required and
3952 calls the statserv_start / statserv_close routines.
3954 Routine zget_SearchRequest and zget_PresentRequest fills
3955 resultSetName/Id member with "default" instead of "Default".
3957 Fixed memory leak in server. Request queue member wasn't freed.
3959 Fixed nmem_exit so that memory is freed.
3963 Revised the CCL parser utility to be thread safe.
3965 Added function, oid_ent_to_oid, to replace the function
3966 oid_getoidbyent, which is not thread safe.
3968 * Added nmem_init and nmem_exit to initialize and release
3969 NMEM resources. Function nmem_init should be called once in the
3970 initial thread before NMEM/ODR is used. statserv.c and client.c
3971 have been changed accordingly. The change was necessary to make
3972 NMEM thread safe. The NMEM memory pool is shared amongst threads
3973 in a process. Unix-based applications will still work fine without
3976 Added NT Services interface for the the Z39.50 (statserv) Server.
3977 Refer to the ztest.c source on the usage.
3979 Windows 95/NT port using MSVC5.0. Project files are included in the
3982 * Defined new 'global' handle for the retrieval (data1) system. The
3983 new handled, data1_handle, describes the state of the data1 system.
3984 This handle is passed as first argument to virtually all
3985 data1 related routines. The functions data1_create and data1_destroy
3986 creates and destroys a data1 handle respectively.
3988 Added ODR encode stream member to all backend request structures
3989 init, search, scan etc. This stream should be used to allocate all
3990 memory used for the response when thread safe operation is needed.
3992 Changed the comstack utility, cs_addstr, to be thread safe. The
3993 returned hostname string returned by the function is now part the
3996 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3997 function. The cs_straddr takes a COMSTACK handle as argument, so this
3998 function must be used after cs_create and before bind/connect.
3999 This function is thread safe.
4001 Moved test server to 'ztest' directory - generic server code still
4002 in 'server' directory.
4004 Made prefix query (pquery.c) utility thread safe.
4006 Added new function modifier YAZ_EXPORT to 'export' public DLL
4007 functions when using windows (see include/yconfig.h).
4009 Added definitions to the OID database (util/oid.c) (RVDM).
4011 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
4013 Added call to ccl_rpn_delete in client program.
4015 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
4016 release of RPN structure.
4018 Added support for C++, headers uses extern "C" for public definitions.
4019 With input from RVDM.
4021 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
4022 Thanks to Ronald van der Meer (RVDM).
4024 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
4026 Added support for private extensions to the OID database
4027 (oid_setprivateoids()). Thanks to RVDM.
4029 Added optional, physical ANY (key replication)
4031 Fixed null-reference problem in GRS-1 output filter.
4033 Proximity operator added to Prefix Query Format (PQF).
4035 In test client command "base" accepts multiple databases.
4037 Fixed bug in cs_close stack that caused trouble with WINSOCK.
4041 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4043 Smallish bug-fixes in the new encoders/decoders (explain).
4045 Bug fixed in DeleteRequest.
4047 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
4049 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4051 Added SOIF syntax (using private OID for now) to retrieval module and client.
4053 Added Update extended service.
4055 Added SearchResult-1 additional info structure.
4057 Added optional CCL (ISO8777) interpreter as separate module. Available
4060 --- 1.2 1996/6/10 (1st anniversary release)
4062 Added Summary record syntax. Lightly tested.
4064 Added OPAC record syntax. Untested.
4066 Added ResourceReport service encoders/decoders. Untested.
4068 Fixed bug in z_Unit - wrong tagging on unitSystem.
4070 Fixed bug in the DiagRecs decoder.
4072 Added options for max PDU size and session timeout to frontend-server.
4074 Added documentation of query-language parsers and other supporting utilities.
4076 [frontend-server] Added Attribute set to the bend_scanrequest API.
4078 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
4079 surrogate diagnostics were generated.
4081 [retrieval] Allow multiple local values for attribute.
4083 [retrieval] Allow multiple attributes per element in .abs files. index type.
4085 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
4087 --- 1.1pl2 1996/4/10
4089 Minor changes, mostly specific to Zebra's requirements (retrieval)
4093 Repaired bug in frontend server when running multiple listening
4094 endpoints in dynamic mode.
4096 z_External() now won't break if a known, ASN.1 value comes encapsulated
4097 in an octet-string. The value will pass through unmodified in an Odr_oct.
4099 Added a bit of code to the demo client to decode & display
4100 ASN.1-structured records represented in the octet-aligned branch of
4101 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
4103 Added z_ext_getentbyref() to the ASN module. Doc updated.
4105 * Completed the SCAN definition in the ASN module. This may break SCAN
4106 code based on older YAZ-versions at compile-time. The fix is easy -
4109 * Added 'displayTerm' and OtherInformation to the TermInfo structure
4110 under the SCAN definition. Remember to initialize this, server-people.
4112 Comstack should now support the WAIS protocol in TCP/IP mode. Note
4113 that this does not extend to ODR and ASN.
4115 Comstack allows insertion of established socket (primarily for
4116 inetd-operation of servers). Doc updated.
4118 Front-end server can now start from the inetd in TCP mode. Doc
4121 --- 1.0pl4 1996/1/24
4125 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
4126 the rank and record number.
4128 Adjustments to the frontend server.
4130 Fixed diagnostic BER dumper. It ignored the file argument.
4134 Various changes to retrieval module.
4136 Changed the union discriminators of the protocol files from enums to
4137 ints paired with #defines.
4139 *Changed oident.class to oident.oclass to avoid a reserved word in C++
4142 *Changed operator in the RPN structure to 'roperator', again to avoid a
4145 Fixed problems in Explain decoders/encoders.
4147 --- 1.0pl2 1995/12/6
4149 Memory bug in log module fixed.
4151 --- 1.0pl1 1995/12/5
4153 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4155 Bug in Explain DatabaseInfo module fixed.
4157 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4161 The shift to v1.0 signals that we now consider the *core* functionality
4162 of YAZ reasonably stable (the core being more or less equivalent to
4163 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4164 tested (Explain not at all - though that will happen soonish).
4166 Minor changes to code to support Windows port.
4168 Various minor changes after we're getting to use GRS-1 & co. more.
4170 Added Espec-1 format.
4172 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4173 of the protocol and it cannot be selected when encoding (maps into 'string'
4174 when decoding). Needed to talk to some servers.
4176 Demo client can request simple element set names.
4178 Added Diagnostic Format encoders/decoders.
4180 Added simple Close handling to frontend server (no hooks for resource
4181 reporting yet), and demonstration client.
4183 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4185 --- 1.0b3 1995/08/24
4187 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4188 handled incorrectly when records were requested in the searchResponse. This
4189 will only affect you if you use the frontend-server.
4191 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4192 Test-client will ask for and print GRS1. Ztest will return dummy records
4195 Added Explain encoders/decoders to the service-level API. Untested.
4197 Added Extended Services: Item Order encoders and decoders to the Service-
4198 level API. Untested. We could use a recent copy of the pertinent bits
4199 of the ILL protocol to add those bits.
4201 Added diagnostic format 1 encoders/decoders to the service-level API.
4204 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4205 odr_cons.c, which causes a more correct output.
4207 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4208 was always set to 0 when no records were requested in the searchRequest.
4210 * Added better external-handling. This shouldn't harm old code that
4211 *encodes* externals. It can break code that looks for a
4212 'single-ASN1-type' representation, since those types that are known
4213 are now decoded immediately. Look at the SUTRS sample code in
4214 seshigh.c and client.c. Documentation updated.
4216 Handling of structured records in bend_fetchresponse. Length -1 marks
4217 structured record, type is deduced from format field.
4219 --- 1.0b2 1995/06/27
4220 Fairly quick maintenance release to add SUTRS support.
4222 Fixed handling of SUTRS records in the demonstration client.
4224 * Added format field to the bend_fetchrequest and bend_fetchresponce
4225 structures of the backend API (frontend server). When the record is
4226 returned, the value of the format field is mapped to an OID. The
4227 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4228 of the record. The special value VAL_NONE in the bend_request means
4229 that no specific format was requested by the client. Documentation
4230 updated accordingly. Test server (ztest) will return a fixed dummy
4231 SUTRS record if your client requests SUTRS.
4233 Documentation updated accordingly.
4235 You can now set external libraries and RANLIB support in the top-level
4239 First public release.
