9 Document itemorder-setname and list all ILL options
13 Extend get_org_info (snippets) to return original string YAZ-836
14 Two new functions have appeared: icu_chain_get_org_info2 and
15 icu_iter_get_org_info2 with a 4th parameter being a pointer
16 to the original string.
18 Fix tcpip.c compilation failure on VC9 YAZ-835
20 Fix icu_iter_get_norm returns invalid size for some input YAZ-834
21 The icu_iter_get_org_info returns information based on string
22 as it appears on tokenize step.
26 Deal with excess bytes in HTTP response for keepalive YAZ-830
28 Refactor ssl_put and tcpip_put to one function YAZ-832

32 Fix SEGV yaz-client for HTTP decoding error YAZ-829
34 Fix buffer overflow in cmd_elements in yaz-client YAZ-828
38 Fix test_sru.sh fails in pazpar2 YAZ-826
39 Unfortunately a regression occurred with YAZ 5.10.0 that would make
40 Pazpar2 fail for HTTP connections.
44 Use CONNECT for SSL backends and for Z39.50 thru HTTP proxy YAZ-825
45 Introduce cs_create_host2 which returns if connection should be
46 proxy aware (HTTP:absoluteUri or Z39.50 proxy:vhost in init).. For CONNECT,
47 the connection is NOT proxy aware (no absoluteUri and no Z39.50 vhost).
49 Fix http proxy fails with yaz-client YAZ-824
53 Fix 0 ptr reference for OPAC records from XML YAZ-822
57 Extend yaz daemon facility to assist int log rotation YAZ-818 YAZ-819
61 record conv: 'select' return org record if no x-path match YAZ-814
63 retrieval: pick matched element-set rule YAZ-813

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

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

236 Build packages for Ubuntu Trusty Tahr 14.04 LTS
238 wrbuf_cstr: fix off by one error.
240 wrbuf_buf: make it always return non-NULL
241 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
245 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
247 zoomsh: offer option -a apdulog
248 As we're used to from yaz-client and GFS based servers.
250 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
251 existing setting apdulog takes effect.
253 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
258 Add re-entrant CQL/Solr/RPN query conversion functions.
259 The re-entrant functions are: cql_transform_r,
260 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
261 These have same functionality as cql_transform,
262 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
263 return the additional infomration as WRBUF to make them re-entrant.
265 Remove CQL to Solr conversion and base solr_transform_t on
266 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
267 data structure as cql_transform_t.
269 cql2pqf utility allows RPN to Solr conversion
271 Fix assert in ZOOM when http connect fails YAZ-757
273 --- 5.0.22 2014/04/09
275 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
277 wrbuf_cstr: make it thread safe YAZ-753
279 yaz_log_init_file may take fd=<no> to open log file at the FD given.
281 --- 5.0.21 2014/03/21
283 Offer new utility function zget_AttributeList_use_string.
285 New conversion step, solrmarc, for record conversion module.
287 --- 5.0.20 2014/03/13
289 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
290 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
293 --- 5.0.19 2014/03/10
295 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
296 The standalone ZOOM sort was completely broken since 5.0.13.
298 ZOOM: generate event Connect rather than None for partial connect
299 (in fact getaddrinfo resolving).
301 ZOOM: only supply clientIP for InitRequest. Rather than for all
304 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
306 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
307 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
308 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
310 New "Facets" section in the documentation.
312 --- 5.0.18 2014/02/27
314 Call exsltRegisterAll in yaz_init_globals, so that all applications
315 using YAZ will have EXSLT things enabled.
317 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
319 Update various URLs to the re-organized SRU pages at LoC.
321 --- 5.0.17 2014/02/26
323 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
324 introduced in 5.0.12.
326 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
327 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
328 Do not call yaz_init_globals from log_mask_str_x. Problem introduce

333 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
335 --- 5.0.15 2014/02/24
337 Fix gcrypt not properly initialized YAZ-740.
339 --- 5.0.14 2014/02/19
341 Describe memcached option for ZOOM.
343 ZOOM: throw present request out of range again YAZ-739
344 Was removed in YAZ 5.0.13.
346 --- 5.0.13 2014/02/18
348 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
349 with localtime_r when threads + fork is used (such as Metaproxy).
351 yaz-config: quote some RHS values (that might include blanks)
353 zoomsh: shows SearchResult-1
355 zoomsh: sortby command
357 zoomsh: use proper list of connections and result sets YAZ-725
359 Avoid yaz_log in sigterm handler for GFS YAZ-737
360 Logging is still performed, but outside sig handler.
362 New ZOOM C feature: result-set caching with memcached. Example:
363 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
365 Remove SSL via OpenSSL support YAZ-732
366 Also deprecate two functions from comstack that aren't working with
367 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
369 Revert "Bison: use %name-prefix directive rather than -p option"
371 --- 5.0.12 2014/01/22
373 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
375 SRU GET/Solr base URLs may hold additional ?args YAZ-729
376 ZOOM option extraArgs already does this, though. It seems useful
377 when dealing with Solr targets to limit by filter, eg.
378 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
380 Remove #fragment for HTTP request encoding YAZ-730
382 Doc: Update list of DLLs/LIBs
384 Doc: update href link to Unix utils and Git.
386 --- 5.0.11 2014/01/15
388 ZOOM: fix "lost connection" problem with servers that uses both squid
389 and another proxy behind it that returns Location headers with relative
392 zoomsh: do not use readline for stdin (no tty) YAZ-724
393 Just use fgets in that case. If the user hits Ctrl-D a new-line
396 zoomsh: empty command ignored YAZ-723
397 rather than performing exit of zoomsh.
399 yaz-url utility offers option -v to enable verbose mode.
401 yaz_url uses yaz_check_location and offers verbose mode.
403 Add new function yaz_check_location.
404 This function gets an absolute URI from Location (HTTP redirect).
406 cookie API: introduce yaz_cookies_reset
408 Update cql.y for newer bison YAZ-720
409 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
410 longer supported. Instead one must use %lex-param and %parse-param .
412 --- 5.0.10 2014/01/09
414 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
417 rpn2solr: support truncation left(2), left&right(3) YAZ-718
419 Mention SRU version 2.0 in yaz-client man page.
423 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
428 Make cs_parse_host public.A
430 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
431 introduced in YAZ 5.0.6.
435 Fix buffer corruption for yaz-ztest record fetch.
439 Allow yaz-ztest to return user-defined records (one record per file).
440 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
442 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
443 Use the stream write instead of odr_printf which has a 4K tmp buffer.
445 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
449 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
450 can read and write this format. For record format JSON, yaz-ztest returns
451 MARC-in-JSON records.
453 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
454 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
458 Improve error reporting for ICU chains YAZ-707
459 Report config element+rule when ICU status is "failure".
461 ZOOM: stop fetching if present response has no records YAZ-710
462 Some targets return less records than their hit count would suggest.
463 This prevents ZOOM from continuing to fetch records if any present
464 response has 0 records in the response.
466 Ensure that GFS calls exit if any listener fails YAZ-710
467 Before, if XML config was in use, it would start the default
472 yaz-ztest: -V shows version (like yaz-client -V)
474 New iconv encoding: danmarc YAZ-692
476 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
478 daemon: only wait for immediate child rather than all children. YAZ-704
480 yaz-client: fix setting of SRU record schema. If scheme was unset, it
481 could lead to invalid memory reference.
485 yaz-ztest returns schema for MARCXML test records. SRU require that
486 recordSchema for records.
488 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
489 instead of non-surrogate diagnostic. This is a per-record failure.
491 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
492 may refer to multiple listeners now. Attribute listenref is a comma separated
495 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
496 option is given for GFS, the dirname of filename (for -f) is used
497 as prefix for options such as cql2rpn, ccl2rpn, etc.
499 Content-Type charset fixes YAZ-701 . Do not inspect charset in
500 Content-Type header for SOAP when decoding SRU. The payload (XML)
501 itself tells what encoding it is. In response, never supply encoding
502 in Content-Type. The response payload (XML) tells what it is (with no
503 encoding in XML it's UTF-8).
505 HTTP decoding: allow blanks in URL paths YAZ-700
509 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
510 and facets. Ensure recordData and recordSchema are always present in
511 record element, because they are required.
513 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
516 Simplify in a lot of places using odr_strdupn.
518 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
522 Increase various buffers in GFS's statserv_options_block
523 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
524 This change makes many type-casts redundant, and, thus simplifies code.
526 Remove last bits of WAIS support.
528 Remove member 'size' from Odr_oct.
530 Slim down the public part of 'struct odr'. Most elements are not part
531 of struct Odr_private.
533 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
534 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
535 In particular facets are supported in both client - and server side.
536 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
537 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
538 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
539 both request/response). This is what a search handler in the GFS
540 will see (regardless of whether operating in SRU mode or Z39.50).
542 Changes to the srw.h (SRU/Solr) definitions include:
543 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
544 (char*), which replace union query and query_type (int). This is because
545 SRU 2.0 supports a queryType parameter. This also means that, to carry
546 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
547 x-pquery=PQFstring (extention parameter). The extension parameter
549 - New element, packing, that has information about SRU
550 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
552 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
554 New element, packing, in Z_SRW_explainRequest.
556 New elements in Z_SRW_scanRequest, queryType and scanClause.
557 These replace query_type and scanClase untion. This is similar to what
560 --- 4.2.69 2013/10/01
562 GFS: log when closing down - at least SIGTERM YAZ-684
563 Also change formatting WRT PID logging a bit.
565 Improve display of MARC records with multi-byte subfield IDs YAZ-695
566 In some rare cases subfield identifiers are multi-byte characters.
567 This will try to deterime length of those and split accordingly.
568 This affects display in line mode as MARCXML/MarcXchange. The encoding
569 of ISO2709 is the same.
571 Change inp argument to const for yaz_read_UTF8_char.
573 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
575 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
577 Better check of marc leader info YAZ-691
578 Problem is that some systems generate MARCXML/MarcXchange with
579 funny headers. These will not work if encoded as ISO2709.
580 Some tests produce new output, due to updated warning messages
582 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
584 yaz-client: display MAB records YAZ-689.
585 Thanks for Heiko Jansen for this patch.
587 New utility z_get_HTTP_Response_server which allows both HTTP server name
588 and HTTP server URL to be given in response.
590 Debian: do not depend on obs tcl8.3.
592 Debian: do not depend on obs libicu36-dev.
594 --- 4.2.68 2013/09/23
596 GFS: pass additionalSearchInfo to search memeber search_input if
597 given. Otherwise pass otherInfo. Request for facets and other search
598 related things will be passed there in future versions of YAZ.
600 New ZOOM setting, authenticationMode, which allows authentication
601 paramters to be encoded in the URL rather than via HTTP Basic auth.
604 rpn2solr: fix nested AND/OR handling. YAZ-685
606 Add comparison routines for some Z-types, such as NamePlusRecord,
607 RPNQuery, Query, RecordComposition and OtherInformation.
609 --- 4.2.67 2013/09/19
611 Don't decode MAB as MARC. Just like we don't attempt to decode
612 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
614 CCL: allow quoted terms for date ranges. YAZ-681
616 Introduce ccl_parser_qual_search. This function makes old function
617 ccl_qual_search, from YAZ 2, available again.
619 Add yaz_facet_list_to_wrbuf. YAZ-683
621 --- 4.2.66 2013/09/11
623 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
624 schema was given for search. YAZ-675
626 Add Solr date range searches. YAZ-621
628 --- 4.2.65 2013/08/22
630 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
632 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
634 ISO2709/MARC parse most octet aligned records; not just those that
635 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
636 MARC parse more records instead of just dumping as is. YAZ-670
638 ZOOM: proper caching for variations of record schema. YAZ-671
640 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
642 --- 4.2.63 2013/07/17
646 --- 4.2.62 2013/07/11
648 New utility z_get_HTTP_Response_details - an extended version of
651 New utility yaz_url_get_error which returns error message of last
652 failed yaz_url_exec call.
654 yaz-url and url functions: allow max HTTP redirects to be controlled.
656 New functions yaz_file_glob2, yaz_xml_include_glob.
657 These functions takes a flags parameter, which, for now only controls
658 whether to fail inclusion of a non-existing file (without glob
659 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
661 --- 4.2.61 2013/06/20
663 For MARC XML parsing, allow record without leader. A fake/default leader
664 is inserted and a warning is tagged with the record.
666 ICU: fix leak in in icu_iter_get_org_info.
668 --- 4.2.60 2013/06/14
670 ICU: fix bug in icu_iter_get_org_info (un-init variable).
672 --- 4.2.59 2013/06/11
674 Implement z_HTTP_header_remove.
676 --- 4.2.58 2013/06/11
678 ICU: Disallow 0 ptrs for some ICU string utilities.
680 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
681 returns original tokens (before normalization).
683 CCL: avoid z39.58/regex truncation when not needed. Apply only the
684 conversion of those masks, when absolutely necessary.
686 CCL: configurable masking character - @mask. Default masking character
689 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
690 full response anyway, so a Transfer-Encoding header will obstruct the
693 --- 4.2.57 2013/05/15
695 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
696 picking a socket. Problem is that some systems has IPV6 support, but
697 we can't create sockets for them, so we pick AF_UNSPEC first.
699 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
700 use content_len to determine resulting Content-Length in HTTP response
701 and NOT Content-Length supplied in headers by user.
703 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
704 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
706 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
709 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
710 with big endian and unsigned char (by default).
712 --- 4.2.56 2013/04/26
714 Fix yaz-client connect (crash in 4.2.55).
716 --- 4.2.55 2013/04/26
718 Fix proxy/host problem for ZOOM that could occur if unix sockets
721 New Debian package libyaz4-dbg.
723 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
724 differently in tcpip_close.
726 --- 4.2.54 2013/04/17
728 Windows installer of YAZ includes YAZ4J as a component.
730 CQL: allow "extra terms" again, by default. Thus, the CQL parser
731 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
732 and earlier. CQL parser may operate in strict mode where queries
733 not conforming to the standard BNF are rejected (syntax error).
734 Whether the CQL parser operates in strict mode is controlled with
735 cql_parser_strict . Strict mode enabled with option -S for utilities
736 cql2pqf and cql2xcql .
738 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
740 --- 4.2.53 2013/04/10
742 New charset, MARC-8c, which is like MARC-8 but allows control characters
743 0x01 through 0x1F, except ESC to be passed through verbatim.
745 Fix a problem with duplicate sub field character in MARC output. Problem
746 happened only when output was MARC-8 encoded.
748 --- 4.2.52 2013/04/03
750 yaz-ztest: Use hash for fake hit count. Before, random number was used.
751 This is problematic for unit tests using yaz-ztest. This patch also makes
752 a hash for CQL queries. For RPN, any term with a leading digit will be
753 treated as pseudu hit count (to force any particular hit count by a client).
755 yaz-ztest: return unique MARC dummy records. Beyond record offset
756 24, the author surname is patched with offset to make all records
759 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
760 on system wide default (/proc/sys/net/ipv6/bindv6only).
761 @4 binds to IPV4 only. @6 binds to IPV6 only.
763 Update CQL API documentation a bit
765 CQL: don't accept extra terms for queries. Makes the CQL parser
766 stricly conformant to the standard.
768 --- 4.2.51 2013/02/12
770 GFS: scan handler gets extra_args from request and may return extra
771 response data . That's for SRU only.
773 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
775 --- 4.2.50 2013/01/30
777 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
779 OPACXML: sync spelling of availabilityDate in XML to that of Schema
780 opaxxml.xsd. The schema had the correct spelling of this member always.
781 The ASN.1 was mis-spelled and still is (API change) - we are
782 not changing this. However, the OPAC to XML conversion had yet
785 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
788 New function, z_ext_record_oid_nmem, which is similar to
789 z_ext_record_oid but takes NMEM rather than ODR
791 --- 4.2.49 2013/01/18
793 ICU: New conversion element 'join' which joins tokens into one
794 with a custom character given by rule attribute.
796 --- 4.2.48 2013/01/10
798 New GFS search member: present_number. This is a hint to the
799 search handler how many records are going to be fetched immediately
800 following search. There's no guarantee that it's going to be the case,
801 since it depends on hit count (for Z39.50 piggyback) and whether errors
804 Make a few functions static (private). The functions getbyte_stream,
805 ungetbyte_stream and yaz_gets are now private. They were never declared
808 yaz-marcdump: exit(5) for serious decoding errors
810 ISO2709 decoding: be more picky WRT header
812 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
813 was only used as to indicate that next-result-set-position should be
815 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
816 Based on patch from Ashley Sanders.
818 Make some functions static/private in PQF parsing. Those functions were
819 never declared in a public header and so should not be in use by
820 applications based on YAZ.
822 --- 4.2.47 2012/11/23
824 ZOOM: special options to control APDU logging.
825 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
826 logging of APDUs until "saveAPDU" option is set again. If logging is
827 already enabled the effect is that current APDU buffer is cleared.
828 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
829 logging (default behavior on new connection).
830 The APDUs sent/received can be obtained by using
831 Using ZOOM_connection_option_get(c, "APDU") or
832 ZOOM_connection_option_getl(c, "APDU", &l).
834 GFS: relay implementation_version from backend
835 From 3.0.40 and later, implementation_version from backend was
836 not used in init response at all.
838 --- 4.2.46 2012/11/15
840 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
841 mode at all. Probably never did.
843 Make a new version of ztest.pem that, at least, is not expired.
845 --- 4.2.45 2012/11/13
847 Fix description of CCL directive 'case'.
849 More tight checking of form arguments (yaz_uri_to_array). Makes
850 YAZ better at rejecting big and/or bad POSTs.
852 SRU decoding does not report more than up to 10 invalid arguments.
854 rpn2cql: less quotes in generated terms. Semantics unchanged, but
855 it's prettier this way.
857 --- 4.2.44 2012/10/25
859 New utility yaz_decode_init_diag. Defined in proto.h.
861 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
862 given for unix local socket.
863 The COMSTACK string for doing so is:
866 unix:/myfile:tcp:localhost:9999/mybase
867 unix:/myfile:localhost:9999/mybase
868 unix:/myfile:http://fakehost/mybase
870 debian: Use dpkg-buildflags in build process.
872 --- 4.2.43 2012/10/19
874 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
875 global's SRU service uses a recordPosition scheme starting from zero.
876 First record's position should be one
877 according to the standard.
879 --- 4.2.42 2012/10/18
881 Allow more namespaces for SRU. This is to allow, for example, an
882 incorrect namespace returned from server
883 http://services.igi-global.com/sru .
885 Minor fixes for compilation on Windows.
887 --- 4.2.41 2012/10/11
889 daemon: log total number of bad signals from child on stop so that it
890 is more easy to spot problems with child worker processes.
892 retrieval: empty backend name attribute omits element set
893 from being used in retrieval.
895 --- 4.2.40 2012/10/04
897 Implement Solr sort strategy "solr", similar to sru11 sorting.
898 This will implement the correct parameters on Solr requst to do
901 --- 4.2.39 2012/09/28
903 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
906 MARC: Extra/missing indicator handled for MARCXML.
907 The indicator length is given in header and is the same for the
908 whole record. If attributes ind1, ind2 are missing, then content
909 character defaults to blank. Extra indicator attributes (beyond)
910 indicator length are treated as an error.
912 Reformat: delete trailing whitespace
914 --- 4.2.38 2012/09/17
916 MARC: fix non-ASCII characters for leader. This is to ensure we can
917 generate XML in UTF-8.
919 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
920 in one node with structure word.
922 --- 4.2.37 2012/09/04
924 yaz-json-parse: JSON output may be pretty printed by using option
927 Increase default value of max message for Z39.50 Init for GFS, ZOOM
928 and yaz-client. Old value was 1 MB. New value is 64 MB.
930 --- 4.2.36 2012/08/22
932 yaz-client: don't display bogus records from SRU servers. Some SRU servers
933 return more records than given by *maximumRecords*. Skipping those in
936 record_render: simplify buffer return handling and fix at least one bad
937 memory reference, that broke the test_embed_record sometimes.
939 Allow http://user:pass@host notation for yaz_url_exec.
941 zoomsh: allow shell command to be executed. Via the system(3) call.
943 yaz_poll: Allow num_fds == 0
945 yaz-client: fix bad encoding of "itemorder item". The itemorder
946 item <no> - command forgot to use length of encoded Item Request
947 package. Error present since YAZ 3.
949 yaz-ztest: fix bad usage of session handle. Bug was introduced when
950 result sets were saved (271a9c83).
952 SRU recordPacking: guess record packing in response rather than looking
953 at the recordPacking element which, OF COURSE, changed semantics in SRU
956 Decode SRU 2.0 responses. The official namespace for responses, according
957 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
958 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
959 nature.com's server, however, usee namespace
960 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
961 we are now using a glob-expr to match up the namespace. ZOOM C and
962 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
963 I can not find a single real example showing the "real" namespace in
964 the documentation from OASIS. The namespace for requests is different
965 from responses, but this is not added to YAZ yet, when we don't encode
968 --- 4.2.35 2012/06/26
970 zoom/record_render: add support for Base64 decoding fo MARC records
971 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
972 which will decode base64 + ISO2709 marc-8 encoded material from text node
975 --- 4.2.34 2012/06/07
977 Add missing definitions ZOOM_resultset_get_facet_field_by_index
978 and ZOOM_resultset_facets_names.
980 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
983 Change APDU dump printing to avoid long leading blanks. For levels 16
984 or larger the level is shown and the indentation is truncated but
985 recursed with modula 8. This makes it still reasonable easy to read
986 - even for nested BER dumps.
988 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
989 return 0 (incomplete package) in case where the BER package was
990 considered too nested (return value of -2).
992 dumpber: lines of level 15 are not indented further. Two spaces per
993 indentation; indentation 15 or more is indented to a fixed indentation
994 and augmented with a level=<no> indication.
996 zoomsh: increase max size of command+args
998 GFS: No limit in RPN buf size in CQL to RPN conversion.
1000 --- 4.2.33 2012/05/09
1002 New function for daemon utility, yaz_daemon_stop .
1004 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
1006 --- 4.2.32 2012/04/25
1008 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
1009 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
1011 --- 4.2.31 2012/04/23
1013 YAZ daemon utility relays SIGUSR1 to child process.
1015 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
1016 would result in en empty database list - which in turn would result in
1017 encoding failure for search.
1019 Fix reading beyond string in yaz_sort_spec.
1021 --- 4.2.30 2012/04/11
1023 Add two new SRU diagnostics:
1024 236: Access to specified database denied
1025 1015: Init/AC: Maximum number of simultaneous sessions for Userid
1027 Document the very useful ZOOM-C option "apdulog".
1029 CQL to RPN: term may be passed through verbatim. This is enabled with
1030 truncation.cql . The assumption being that the term is already CQL.
1032 --- 4.2.29 2012/03/20
1034 record_conv: leader spec may be given for marc element.
1035 The leader spec is given as attribute leaderspec for element marc.
1036 For example to convert a MARC21 record from MARC-8 to UTF-8:
1037 <marc inputformat="marc" outputformat="marc"
1038 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
1040 record_conv: allow user-XSLT params. For example:
1041 <xslt stylesheet="MARC21slim2DC.xsl">
1042 <param name="myparameter" value="myvalue"/>
1043 <param name="otherparameter" value="othervalue"/>
1046 record_conv: fix error handling for missing marc charsets.
1048 CQL: fix extra terms in wrong order.
1050 --- 4.2.28 2012/03/06
1052 record_conv: modify new API for conversion types. The conversion types
1053 may be passed in new functions yaz_record_conv_configure_t and
1054 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
1056 Avoid mixed statement/variable declare; fixes compilation with Visual
1059 --- 4.2.27 2012/02/28
1061 Add non-standard SRU diagnostic: 235: "Database does not exist".
1062 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
1063 Update SRU to Bib-1 diagnostic maps accordingly.
1065 CCL: add two new diagnostics for unsupported masking. The new
1066 diagnostics are: "Embedded truncation not supported" and
1067 "Single charcacter mask not supported".
1069 --- 4.2.26 2012/02/23
1071 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
1073 --- 4.2.25 2012/01/11
1075 Build YAZ for Ubuntu Oneiric.
1077 CCL: allow parantheses for proximity operands. For example CCL query
1078 (a) % (b) is now allowed.
1080 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
1081 marked dead, rather then being destroyed. If not, the session memory is
1082 being free'd before the search/scan handler is finished. Also destroy
1083 'request' memory in request_release rather than in various places,
1084 which resulted in leaks from time to time.
1086 --- 4.2.24 2011/12/21
1088 cql_sortby_to_sortkeys: honor sort prefix.
1090 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
1091 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
1092 The rpn2cql family of functions now always returns quoted CQL terms.
1094 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
1096 --- 4.2.23 2011/12/15
1098 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
1099 sequence is treated as one. For example, &&a=b&&&c& is identical to
1102 --- 4.2.22 2011/12/05
1104 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
1105 APDUs for a connection to a WRBUF.
1107 --- 4.2.21 2011/11/23
1109 Fix cql_sortby_to_sortkeys. Completely broken before.
1111 Make CCL's @truncation work again.
1113 --- 4.2.20 2011/11/09
1115 New ZOOM connection setting: tproxy. It's like proxy, but does not
1116 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
1117 to set resolved address + port for a connection outside ZOOM itself.
1119 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
1121 --- 4.2.19 2011/11/07
1123 Fix uninitialized variable in Solr spell support (could cause SEGV
1124 for SRU response decoding).
1126 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
1127 back-end's addinfo through into the ZOOM response addinfo.
1129 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
1130 they are separated by a colon and a space rather than simply
1133 --- 4.2.18 2011/10/28
1135 Add support for Solr spell-checking/suggestions through ZOOM.
1136 If a Solr target has been configured correctly for spelling-checking
1137 and suggestions, these will now be returned on the ResultSet option
1138 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1140 --- 4.2.17 2011/09/28
1142 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1143 with a flag whether to substitute escape sequences or not.
1145 --- 4.2.16 2011/09/22
1147 Fix nmem_strsplit_escape to substitute escape char properly.
1149 New option for zoomsh -e , which makes it abort on first error and
1150 return process exit code to indicate success/failure.
1152 YAZ options utility supports special option -- which makes all it treat
1153 all following arguments as non-options.
1155 --- 4.2.15 2011/09/16
1157 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1158 searched if absolute filename is given.
1160 Fix conv_xslt() error-reporting when stylesheet is not found.
1161 (The value of fullpath is meaningless in this situation.)
1163 --- 4.2.14 2011/09/07
1165 Fix problem in CQL sort node creation: un-initialized memory.
1167 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1168 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1169 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1172 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1173 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1175 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1176 will make it possible to use both single-character mask (#) and wildcard (?)
1177 in CCL . Throw diagnostic for left truncation because that is not supported
1180 --- 4.2.13 2011/09/01
1182 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1183 cases using escapes (\-sequences) and masking.
1185 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1186 would result in a read one byte beyond string.
1188 rpn2ccl may use Z39.50 masking for terms (t=z).
1190 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1192 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1193 not --cppflags (which seeems like an error in icu-config).
1195 --- 4.2.12 2011/08/27 RPM package only
1197 cql2ccl: fix conversion of terms: operator characters were not
1200 --- 4.2.11 2011/08/25 RPM package only
1202 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1203 CCL parser will map both # and ? to their regular expression
1204 quivalents (. and .*).
1206 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1207 of reserved CQL characters.
1209 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1210 is, so that they are passed through.
1212 --- 4.2.10 2011/08/24
1214 ZOOM SRU mode: more aggressive re-connect.
1216 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1217 made available as a utility function, declared in <yaz/logrpn.h>
1219 rpn2cql_structure() supports proximity nodes (except that the Type-1
1220 proximity node's "exclusion" binary is ignored, as there is no way to
1221 express that in CQL). Fixes bug #4564.
1223 --- 4.2.9 2011/08/18
1225 Fix SEGV that could occur if set command of zoomsh was given without
1226 value (2nd argument).
1228 Fix SEGV that could occur if unsupported transport was given for
1229 COMSTACK - say https (when SSL was unavailable).
1231 Build yaz-url on Windows too.
1233 --- 4.2.8 2011/08/11
1235 New utility to get web content. Header is url.h. A command line tool
1236 yaz-url is part of the distribution and packages.
1238 Fixes for SSL COMSTACK (when gnutls is in use).
1240 New functions yaz_base64{encode,decode}. Header is base64.h.
1242 --- 4.2.7 2011/08/03
1244 ZOOM C includes HTTP response buffer as additional info if it fails
1245 to decode the SRU response.
1247 Make wrbuf_json_puts available.
1249 --- 4.2.6 2011/07/28
1251 zoom: throw diagnostic for invalid value for option "sru". Before a
1252 bad SRU request was sent.
1254 Adding new utility wrbuf_vp_puts.
1256 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1258 --- 4.2.5 2011/07/21
1260 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1261 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1262 redirect was used at the same time.
1264 MARC line mode decoding: be less picky about length given - first
1265 5 digits of header that is.
1267 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1269 Changes to decoding of SRU records: a record with recordPacking=xml is
1270 modified with a new root element <yaz_record> if the recordData contains
1271 multiple children elements. This is to make the record XML parseable
1274 RPN to Solr conversion: encode special characters.
1276 Generic Frontend Server: fix uinitialized member, stepSize.
1278 --- 4.2.4 2011/06/21
1280 Fix a bug in SRU decoding of records.. The database records stored
1281 had un-initialized memory, but it would only be seen with yaz_record_render
1282 and type_spec="ext" .
1284 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1286 --- 4.2.3 2011/06/17
1288 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1290 --- 4.2.2 2011/06/10
1292 Add new utilities to convert from CQL to CCL . These utilities have
1293 prefix cql_to_ccl defined in cql.h.
1295 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1296 lead to memory heap corruptions when ICU utilities were in use.
1298 --- 4.2.1 2011/06/07
1300 Make compilation work without Libxml2.
1302 yaz-client: remove redundant blanks in display of searchResult-1 term
1305 --- 4.2.0 2011/05/18
1307 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1308 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1310 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1311 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1312 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1313 Note that the CQL sortby spec is only converted when the GFS is already
1314 converting from CQL to RPN (cql2rpn element).
1316 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1317 specify whether to collapse delimitors or not. The existing nmem_strsplit
1318 do collapse (collapse parameter = 1).
1320 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1322 Rename internal func yaz_use_attribute_create. While non-static, this
1323 function is not declared in a public header.
1325 --- 4.1.7 2011/03/15
1327 Add -lCrun when linking with ICU on Solaris.
1329 More quicks character set conversions for OPAC records.
1331 --- 4.1.6 2011/03/10
1333 fix problem with record_render: records were converted (character set
1334 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1336 --- 4.1.5 2011/03/08
1338 SRU: add methods for handling DADS SRU-proxy facets.
1340 Separate OPAC record character set for ZOOM_record. yaz_record_render
1341 allows a character set given as charset=from/opacfrom,to where 'from' is
1342 the character set of a bibliographic record, 'opacfrom' is character set
1343 of OPAC record and 'to' is the target character set.
1345 --- 4.1.4 2011/02/21
1347 yaz-client: show may XML format records. Command show followed by 'format'
1348 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1351 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1354 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1356 --- 4.1.3 2011/01/27
1357 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1359 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1360 this package can be distinguished from other vendors.
1362 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1363 as determined by configure
1365 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1367 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1368 returns no error and no record, the present request is considered
1369 partial (only a subset of the records could be returned by backend), and
1370 so it is appropriate to set Present Status to partial-4.
1372 --- 4.1.2 2010/11/02
1374 Move yaz-config man pages to section 1.
1376 More documentation about Solr.
1378 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1379 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1380 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1381 peers on some Linux systems. However, in general that does not work
1382 so YAZ can not rely on that to work. Debian changed behavior in this
1383 respect from Debian lenny to Debian squeeze (still testing as of Oct
1385 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1387 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1389 --- 4.1.1 2010/10/05
1391 Fix yaz-config output: echo_source not set correctly by configure.
1393 --- 4.1.0 2010/10/05
1395 Solr Web Service support for yaz-client and ZOOM.
1397 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1399 --- 4.0.12 2010/08/17
1401 Z39.50 facet support. Facet specifications are passed for search in
1402 other-information with ASN.1 as defined in facet.asn and OID
1403 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1404 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1405 3 is limit (number of entries to get in response). yaz-ztest returns
1406 dummy facets if a client asks for them.
1408 --- 4.0.11 2010/07/09
1410 CCL fixes: bug 2895 and bug 3539.
1412 GR1-display: add comma in display - was removed by mistake in
1415 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1417 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1419 --- 4.0.10 2010/06/18
1421 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1422 result set from a connection. The result set will be on its own
1423 thereafter; no operations on it will perform retrievals from a target.
1424 Only cached copies are returned.
1426 ZOOM C:fix case for HTTP servers responding with Connection:close.
1427 Ensure that if there is a current task it is resumed (like fetching
1428 more records in a result set) . Bug #3484.
1430 PQF parser: use odr_atoi for Odr_int (not atoi)
1432 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1433 values that contain any non-digits are treated as string attributes
1434 (previously decoding only checked for leading character ([0-9]). PQF
1435 encoding: attribute string values are not surrounded by double-quotes.
1437 --- 4.0.9 2010/05/21
1439 New utility for managing threads - thread_create.h.
1441 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1442 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1443 but YAZ' implementation do.
1445 Fixes for yaz_cond-functions on Windows 7.
1447 DLL export more symbols.
1449 zoomsh: show record do NOT render opac.
1451 Remove *.la files from Debian and RPM packages.
1453 --- 4.0.8 2010/05/11
1455 Debian package libyaz-dev depends on libgnutls-dev again (was
1456 removed in YAZ 4.0.6, but due to Libtool it is still needed
1457 even though yaz-config do not list libgnutls libs).
1459 ZOOM: Use only one WRBUF for returning string results for
1460 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1462 ZOOM: ZOOM_connection do not use a shared pointer to
1463 ZOOM_resultset after ZOOM_resultset is destructed by
1464 user. Reverts to YAZ 4.0.4 behavior.
1466 --- 4.0.7 2010/05/04
1468 record-conv: fix problem with at least one XSL conversion -
1469 due to probably incorrect usage of XML XSL documents.
1471 --- 4.0.6 2010/04/29
1473 Fix yaz-config for static mode and the use of SSL (gnutls).
1475 --- 4.0.5 2010/04/29
1477 Forward decl timeval struct in mutex.h and gettimeofday.h.
1479 yaz-config: fix 'static' mode linking.
1481 --- 4.0.4 2010/04/28
1483 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1484 are wrappers for pthreads or Windows. For Windows these are put in
1485 a separate DLL: yaz_cond4.
1487 libyaz.la (whole source) is compiled with thread. If thread support
1488 is enabled enabled, all source of YAZ is compiled with treading support.
1489 This allows core utilities such as yaz_log to use thread facilities.
1490 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1491 thread utilities. This commit moves mutex utilities (mutex.c) from
1492 libyaz_server.la to libyaz.la.
1494 yaz-json-parse displays leading text until error.
1496 --- 4.0.3 2010/04/09
1498 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1499 patch from Giannis Kosmas.
1501 SRU: no longer URL encode SRU database. The URL for an SRU server is
1502 a URL and such is alreeady encoded - at least when given with leading
1503 http:// or https://. This reverts behavior to YAZ 3.0.50.
1505 Support for new MARC XML notation TurboMARC which like MARCXML is a
1506 complete representation of MARC/ISO2709.. This one, however, is more
1507 compact and allows for faster processing with XSLT. TurboMARC can be
1508 used in the marcdisp.h API, from the yaz-marcdump utility and from
1511 yaz-ztest can be configured - via the database - to perform certain
1512 delays when it performs operations search, present and single record
1513 fetch. This allows testers to make yaz-ztest act as a real or even slow
1514 Z39.50 server. Refer to the yaz-ztest man pages for details.
1516 --- 4.0.2 2010/03/09
1518 wrbuf_destroy allows NULL WRBUF passed to it.
1520 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1522 Add ZOOM_connection_close.
1524 No fixed size buffers for ZOOM shell - bug #3257.
1526 tstodr: make it work on s390 platform.
1528 New icu iterator-functions. The new icu_iter-functions makes it possible
1529 to use ICU chains from many threads.
1531 yaz-client: better syntax check for show command.
1533 --- 4.0.1 2010/01/26
1535 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1538 New simple local-file XML include facility which allows file glob-patterns.
1539 Refer to yaz/xml_include.h.
1541 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1544 ZOOM_record_get supports new parameter "format" which makes it format XML
1547 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1548 JSONText in ECMA-262) is JSONValue, not JSONObject.
1550 --- 4.0.0 2010/01/20
1552 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1553 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1555 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1556 POSIX/Unix builds .so with major version 4.
1558 Remove old LOG_-defines from log.h. They have been obsolete and
1559 undefined by default for the last 5 years.
1561 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1563 GFS: Remove socket (int *fd) from search_rr handler. The socket
1564 descriptor ptr is a facility that allowed a search handler to supply
1565 a socket which would serve as a callback - when search was complete.
1566 This facility has now been in use for years.
1568 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1569 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1570 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1571 returns 'const char *' rather than 'char *. The returned string is
1572 read-only and should not be modified by applications. COMSTACK cs_close is
1573 now a void function - it no longer returns int. No applications check for
1574 the value and the implementations has always returned 0.
1576 ZOOM: use size_t for scan hit counts and str size. Functions
1577 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1578 occ (hit count) and len (string length) are now of type size_t pointer
1579 rather than int pointer. This is to be able to represent large hit counts
1580 and to also just to use the proper type for string length (strlen result).
1582 New JSON parser. Refer to include/yaz/json.h .
1584 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1585 Used to be int in some cases. Many wrbuf_-functions used to return an int
1586 indicating some length.. These return values were never used. And so they
1589 ODR: odr_malloc, odr_total now takes size_t for size.
1591 clone_z_type: fix leak; occurred for encoding failures.
1593 --- 3.0.52 2009/12/03
1595 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1596 bug was introduced in 3.0.51.
1598 --- 3.0.51 2009/12/02
1600 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1602 tcpip comstack: fix leak for getaddrinfo.
1604 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1605 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1606 Decoding of SRU "path" database is performed by private function
1607 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1608 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1610 yaz-client: honor base command for SRU. Change when database setting
1611 is applied for SRU and ensure it is kept when a connection is reset.
1612 Change also the way errors are displayed or SRU (decoding of packages).
1614 --- 3.0.50 2009/11/02
1616 Add support for extra request / response data for SRU codecs and GFS.
1617 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1618 for extra data response buffer and length. For the GFS, both request
1619 and response data (XML) is carried in extra_args and extra_response_data
1620 for the search handler. Patch by Ko van der Sloot.
1622 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1623 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1624 10010). This fixes bug #2113.
1626 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1627 cmdfile included a 'quit' command that would result in a memory violation.
1629 --- 3.0.49 2009/10/01
1631 Make a number of functions defined in xmlquery.c static. These have
1632 never been declared in a public header file (yaz/xmlquery.h) and was
1633 made public by mistake.
1635 Improve speed of character conversions (iconv utilities). This makes
1636 conversions from MARC-8 faster.
1638 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1639 unless type desired is "raw". This will prevent type "xml" from
1640 returning ISO2709 .. Which obviously can not be XML parsed.
1642 Fix memory leak in ZOOM that would occur if option apdulog was used
1643 on a re-used connection.
1645 Frontend server logs HTTP requests.
1647 Frontend server now sends Z39.50 close when it times out (sesssion has
1648 been idle for too long). Versions 2.0.30 and earlier also sent close.
1649 But due to a mistake this was disabled in all versions after that, i.e.
1650 the server would just close the socket immediately.
1652 yaz-client emits a better message when receiving an unrecognised
1653 userInformationField.
1655 Skip zero-length subfields when decoding ISO2709. This rare case happens
1656 if a record has two FS characters in a sequence. Without this patch
1657 there would be a reference beyond char array in using_code_len fragments
1660 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1662 --- 3.0.48 2009/08/28
1664 The show command offered by the zoomsh command now takes a 3d optional
1665 parameter type which is what is passed to ZOOM_record. If the type
1666 argument is omitted, "render" is used.
1668 RPN to CQL conv may use USE string attributes (bug #2978).
1670 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1672 --- 3.0.47 2009/07/08
1674 Function yaz_xml2query allows a diagnostic element in the PQF XML
1675 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1676 code and additional info respectively.
1678 The BER BOOLEAN is now the integral type Odr_bool which still happens
1679 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1680 typedef'd to Odr_int. This is still an integral 'int', but it may be
1681 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1682 ASN-1 compiler as well as programs has been updated to use the new types.
1684 --- 3.0.46 2009/06/08
1686 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1687 only the bibliographic record was rendered. For type=opac, an OPAC
1688 record is only returned if it is present.
1690 iconv: small fix for encoding of advancegreek.
1692 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1694 yaz-client: option auto_reconnect=on really reconnects.
1696 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1698 server: avoid null ptr ref for for yaz_poll errors.
1700 build: fix RPM build for RHEL 5.3.
1702 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1704 --- 3.0.45 2009/03/31
1706 Fixed bug #2709: TCP connect returns Invalid argument.
1708 Fixed compilation for mingw.
1710 Honor charset for raw records (ZOOM_record_get).
1712 Fixed use of errno for threaded mode that was seen on Solaris 10.
1714 Fixed argument passing with blanks in value for Windows Service.
1716 Disable YAZ' own log rotate by default (no 1 GB limit).
1717 The variable l_max_size which specifies the log file limit is set to 0
1718 (DISABLED): This is due to the fact that YAZ is most often deployed using
1719 logrotate. Also YAZ can not perform log rotate because of unsufficient
1720 permissions (setuid).
1722 --- 3.0.44 2009/02/17
1724 List supported encodings in man page for yaz-iconv.
1726 Fixed missing SSL libs for --libs output
1728 Re-established OID record syntax application-xml. Nobody should use it
1729 but we don't want to change soname because of this symbol being absent.
1731 --- 3.0.42 2009/02/02
1733 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1735 Added member named_result_sets for init handler struct for the GFS. This
1736 allows a server to disable named result sets.
1738 Removed OID record syntax application-xml.
1740 Added support for rule-based transliterator for ICU wrapper of YAZ.
1742 Fixed bug #1902: yaz-icu XML output.
1744 Make YAZ checks Emacs friendly.
1746 BITSTRING value shows value. Bug #2346.
1748 ISO2709 decoding: skip control characters from indicator data.
1750 Omit sort key by default in yaz-icu's output.
1752 Allow combined single char options (again) for YAZ' options function.
1754 Utility yaz-marcdump got option to display YAZ version (-V).
1756 Allow YAZ to use ICU 3.4.
1758 Added new ICU test case which illustrates removal of diacritics.
1760 --- 3.0.41 2008/12/29
1762 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1764 --- 3.0.40 2008/12/29
1766 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1769 Fixed bug #2352: yaz-marcdump crashes for certain record.
1771 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1773 Added support for Danmarc2 to UTF-8 conversion.
1775 Added support for ISO5426 to UTF-8 conversion.
1777 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1778 implementation version.
1780 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1782 --- 3.0.38 2008/11/10
1784 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1785 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1787 ZOOM C now interprets databaseName option for ZOOM connection as path
1790 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1792 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1794 Dummy Libxml2 types no longer defined in headers of YAZ'.
1796 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1799 --- 3.0.36 2008/09/26
1801 Various ODR chapter fixes.
1803 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1805 Added missing source for Windows compilation, mutex.c.
1807 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1809 For SRU connections in ZOOM all records up to "count" are now fetched.
1811 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1812 in Windows due to bad error handling for Libxml2.
1814 Added facility for sending arbitrary records (ASN.1 any) using
1815 ZOOM C's Extended service update. Patch by Sam Reynolds.
1817 New options for ZOOM C's connection, logapdu which makes ZOOM log
1820 --- 3.0.34 2008/06/18
1822 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1824 --- 3.0.32 2008/06/12
1826 Fixed memory violation that could occur when decoding UTF-8. This bug
1827 was only present in 3.0.30 of YAZ.
1829 --- 3.0.30 2008/06/06
1831 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1832 GNU TLS is used by default (if found).
1834 yaz-ztest returns OPAC records if a client asks for OPAC.
1836 Improved speed of MARC-8 encoding.
1838 Added support for lossy and loss-less MARC-8 encoding.
1840 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1842 Added new Windows Service wrapper (sc).
1844 yaz-client's itemorder command may now send a file.
1846 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1848 Added new function yaz_log_xml_errors.
1850 Allow (but warn) unknown XML attributes in MARCXML parsing.
1852 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1854 The UTF-8 to MARC-8 conversion now uses a different set of characters
1855 for Greek symbols. Bug #2120.
1857 --- 3.0.26 2008/02/21
1859 Added yaz_daemon (daemon.h).
1861 Fixed bug #2068: pkg-config trouble
1863 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1865 --- 3.0.24 2008/01/28
1867 Document --with-xml2 option.
1869 Added OPAC XML XSD (etc/opacxml.xsd).
1871 Allow glob mask for name attribute in retrieval element for the
1872 generic frontend server's retrieval facility.
1874 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1875 except POLLIN/POLLOUT.
1877 Fixed error handling in cs_listen. Bug #2037.
1879 --- 3.0.22 2008/01/20
1881 Fixed version in yaz/yaz-version.h.
1883 Fixed bug #2027: Crash when closing connection.
1885 Changed configure so that ICU support is only enabled if only ICU
1886 and Libxml2 is available (because the ICU chain is XML based).
1888 --- 3.0.20 2008/01/15
1890 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1891 is built. Only this DLL depends on the ICU runtime.
1893 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1894 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1896 Changed license of CCL module to 'Revised BSD'. After consultation with
1897 remaining members of the original EUROPAGATE consortium, we are re-issuing
1898 the CCL module without a separate license. The software was developed by
1899 Index Data as part of a research project. The special license was included
1900 to help feed usage information back to the project consortium to support
1901 project evaluation. At this time, the project consortium has long-since
1902 disbanded, and the majority of the original principals have retired. At the
1903 same time, we have significantly modified the software during the following
1904 years, to the point where very practically no original code remains. To
1905 simplify re-use of the software, we have contacted those members of the
1906 consortium who could be reached, and agreed to re-issue the module as a
1907 proper part of the YAZ package.
1909 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1911 CQL closer to being version 1.2 compliant. CQL also allows free-form
1912 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1915 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1916 bug could make Extended services handling crash in the ZOOM layer. This
1917 bug was only present in YAZ 3.0.18.
1919 --- 3.0.18 2007/12/19
1921 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1924 yaz-marcdump reads and writes collection wrapped records.
1926 Handle OPAC for record conversion module.
1928 Fixes for ICU wrapper.
1930 Allow ICU libs to be controlled with --with-icu .
1932 --- 3.0.16 2007/11/12
1934 Added yaz_poll which is a wrapper for select/poll. When poll is available
1935 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1936 sockets to be in use.
1938 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1939 functionality through an XML based configuration (ICU chain). This system
1940 is useful for search facilities such as Pazpar2 and Zebra that needs to
1941 perform tokenization of indexed material. The ICU code in a separate
1942 library libyaz3_icu.a.
1944 Added HTTP tunnel facility for COMSTACK, bug #1752.
1945 This is a facility that allows a Web proxy, such as squid, to tunnel
1946 Z39.50 traffic. This facility is "transparent" to must applications
1947 using YAZ. It's enabled by using pseudo transport connect: followed by
1948 the proxy address, followed by command, then follwed by he regular
1949 "virtual" addresss. For example,
1950 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1952 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1954 --- 3.0.14 2007/09/21
1956 Fixed bad memory reference in ZOOM_record - cuased by member not being
1957 initialized. This was a problem only in YAZ 3.0.12.
1959 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1960 fields were not removed.
1962 Changed the way C code is generated from codetables.xml. Made a MARC-8
1963 conversion trie for each characterSet section rather than codeTable.
1964 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1965 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1967 --- 3.0.12 2007/09/12
1969 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1970 from ZOOM_record_error).
1972 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1974 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1976 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1978 Better SRW-to-Bib-1 diagnostic mapping.
1980 ZOOM C and yaz-client announces SRU version 1.2 by default.
1982 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1985 Fixed in yaz_sru_decode to allow other version than 1.1.
1987 --- 3.0.10 2007/08/22
1989 Added support for SRU scan for ZOOM.
1991 Added support for the use of the older versions or Extended Service
1992 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1993 set to the version , 1=first, 2=second, 3=third. The third version is
1994 what ZOOM C has used so far. And that, obviously, is the default.
1996 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1997 therefore in Zebra and in SimpleServer-based applications). The new
1998 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1999 qualifier file used to transform incoming CCL queries into Type-1 RPN,
2000 which is passed into the back-end search callback function.
2002 Added support for HTTP Basic authentication in clients: the SRU/W
2003 codec encodes the username/password elements of the PDU structure
2004 appropriately, and these may be set using the "user" and "password"
2005 options in ZOOM-C applications (the same options that are used for
2006 Z39.50 authentication).
2008 --- 3.0.8 2007/06/25
2010 Fixed bug #1208: SSL appears to be broken in ZOOM.
2012 Fixed bug #1206: Libxml2 include path weirdness.
2014 Added oid_name_to_dotstring.
2016 Allow elementSetName to be specified for ZOOM C record update.
2018 Allow waitAction to be specified for ZOOM C based for Extended Services.
2020 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
2021 syntax OID. Bug introduced in YAZ 3 series.
2023 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
2025 --- 3.0.6 2007/06/06
2027 Fixed bug #1157: yaz-client does not read .yazclientrc from current
2028 directory. yaz-client now reads commands from file given by option -f
2029 if specified; then tries to read .yazclientrc in current directory.
2030 Failing that, it reads .yazclientrc from user's home directory.
2032 Added support for correlationInfo Note and ID for Record Update via
2035 Added yaz-client command querycharset which specifies character set for
2036 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
2037 (termListAndStartPoint).
2039 Charset ISO5428:1984 is an alias for ISO5428-1984.
2041 Implemented a way to perform scan in a result set using Z39.50. This
2042 is achieved by attaching the result set name in the characterInfo
2043 (type InternationalString) of OtherInformation in the Scan Request PDU.
2044 The result set is identified in the otherinformation by the new OID:
2045 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
2046 This allows for scan in result set and faceted search . Zebra did some
2047 of this in the APT term using attribute type 8 and value being result
2048 set. Using the OtherInformation approach for this is cleaner and easier
2049 to work with in proxies and the like. This facility can be used in
2050 yaz-client using new command setscan which takes a result set as first
2051 argument, start position (APT) as second.
2053 Changed decoding of SRU XML packed records to deal with servers that
2054 have recordData with XML data with multiple root nodes. Also make
2055 comparison for recordPacking case insensitive. Again, one server
2056 returns "XML" where others return "xml".
2058 For SRU responses allow Content-Type application/xml as well as text/xml.
2060 --- 3.0.4 2007/05/21
2062 Fixed bug in character set conversion of BER strings. Bug introduced
2065 --- 3.0.2 2007/05/08
2067 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
2069 For OID class, use oid_class consistently.
2071 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
2074 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
2075 character set for bibliographic information interchange". By Giannis Kosmas.
2077 Added documentation on new OID API.
2079 --- 3.0.0 2007/05/02
2081 Changes to generic frontend server interface: added new member
2082 'query_charset' for bend_initrequest structure. A backend init handler
2083 should set this member to its native character set for query terms.
2084 When defined, the frontend server logic will announce this character set
2085 to a client if the negotiationModel bit is set by the client. All server
2086 implementors are encouraged to specify this. If a backend server does not
2087 specify this a warning is issued using yaz_log(YLOG_WARN,..).
2089 Added CCL utility to remove terms (stop words) from resulting RPN
2090 tree. This is handled by functions with prefix ccl_stop_words_ .
2092 New ZOOM C option, "rpnCharset", which allows client-side conversion of
2093 terms in RPN queries.
2095 Clean-up the CCL API. Moved some internal structures from ccl.h to
2096 private header cclp.h. Changed ccl_parser_create so that a Bibset must
2097 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
2098 This is replaced by ccl_parser_find_str which takes a string instead.
2100 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
2101 libyaz.la is the core of YAZ except the generic frontend server and
2102 does not depend on POSIX threads anymore. libyaz_server.la is the
2103 generic frontend server facilities and uses POSIX thread functionality
2104 if available. The libyaz.la no longer depends on POSIX threads because
2105 the number of global structures is limited. NMEM no longer re-uses blocks
2106 between threads ; it simply free's memory immediately but allocates in
2107 "large" chunks as usual. We don't expect any performance penalties
2108 because of this. The yaz_log system is still using a global log_level so
2109 caution must be taken when modifying it with yaz_log_init_.. +
2110 yaz_log_mask_str. This, however, should not cause any trouble because
2111 these functions are called during initialization of application code
2112 anyway. `yaz-config --libs server` returns libs for server applications;
2113 `yaz-config --libs` returns libs for non-server applications.
2115 New OID database - with public definitions in oid_db.h. Removed old OID
2116 database including the head oid.h and definitions such as enum oid_value
2117 and struct oident. The new OID database uses the same string names as
2118 before but the 'protocol' is gone. There are now only two representations
2119 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
2120 converts from string to OID; functions with prefix yaz_oid_to_string
2121 converts the other way.
2123 Change to emit_term() in CQL-to-PQF query translation: when a term has
2124 the /regexp relation modifier, do not process it for leading and
2125 trailing "^" and "*", which have quite different meanings in regular
2128 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2129 write handlers no longer carries a 'last' parameter. This will make
2130 yaz_iconv flush "less" characters. A flush is performed by call to
2131 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2133 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2134 removed, because function yaz_query_to_wrbuf does the same.
2136 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2137 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2139 Deprecated MARC utility functions removed.
2141 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2144 Branch split: YAZ_2_1_55_branch
2146 --- 2.1.54 2007/03/16
2148 Fix to ZOOM-C so that transparent reconnection is properly handled on
2149 connections that are in asynchronous mode.
2151 Fixed compilation on OpenBSD 4.0.
2153 Large strings in GRS-1 records are now properly displayed in yaz-client.
2155 Added character conversion support for "advancegreek"; based on patch from
2158 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2159 sequence is met. Before the error was not set so it would be unknown.
2161 Adjust yaz-marcdump MARC reader so that it skips until record separator
2164 --- 2.1.52 2007/03/07
2166 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2167 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2168 fd_set structure used as a bitmask for the FDs to be selected on.
2170 Using ACX_PTHREAD macro to check for POSIX threads.
2172 Fixed have-vsnprintf check.
2174 --- 2.1.50 2007/02/23
2176 Fixes for configure on BSD. Bug #900.
2178 Added snprintf/vsnprintf wrappers for systems that don't have
2179 limits (heavens forbid).
2181 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2182 created before all previous tasks were completed and removed from the
2183 task queue, the new task could be removed by a mistake.
2185 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2187 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2189 Fixed bug #832: Problem with MARC/charset in yaz-client.
2191 Fixed bug #668: save command line history for yaz-client.
2193 Fixed bug #830: pkg-config support.
2195 --- 2.1.48 2007/01/23
2197 Extended ZOOM result set options with two options that may be read by
2198 a client: resultSetStatus and presentStatus with values as specified for
2200 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2202 Fixed bug #827: Using SSL fails on Debian etch.
2204 Fixed bug #826: Weird looking chars for set of MARC records.
2206 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2207 that is treated as an ItemOrder with itemRequest being an XML document
2208 external. The value of "doc" is the content.
2210 Extended the GFS search facility. New member of bend_search_rr
2211 'estimated_hit_count' signals that hits is known to be an estmate
2212 (higher or lower than real hit count). New member 'partial_resultset'
2213 signals that the search was partial (hit count is lower or equal than
2214 real hit count). For Z39.50, the information is stored in resultSetStatus
2215 member of SearchResponse APDU. For SRU, the information is signalled
2216 via SRU diagnostic 59: "Result set created with valid partial results
2219 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2221 --- 2.1.46 2007/01/13
2223 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2225 Added ZOOM_connection_peek_event.
2227 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2228 the following new functions:
2229 ZOOM_event_nonblock, ZOOM_connection_process,
2230 ZOOM_connection_get_{socket,mask,timeout},
2231 ZOOM_connection_fire_event_{timeout,socket}.
2232 The existing blocking event handler, ZOOM_event, is a wrapper for the
2233 + blocking ZOOM_event_sys_{poll,select}.
2235 Implemented function ccl_xml_config which parses XML version of CCL
2236 configuration (bug #798).
2238 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2240 Added timings utility (yaz/timing.h)
2242 --- 2.1.44 2007/01/03
2244 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2247 Fixed bug #779: Rotation of apdu.log fails.
2249 Fixed for character set conversions:
2250 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2251 Honor G1 set in MARC-8 decoding.
2253 --- 2.1.42 2006/12/17
2255 Fixed bug #775: char conversion does not handle Alternative UTF-8
2258 Implemented function yaz_marc_read_line which parses MARC line format
2259 records. There is a wealth of formats out there. So far, this function
2260 reads line records produced by yaz_marc_write_line.
2262 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2263 more generic and easier to remember(!) options: -i format and -o format
2264 which specifies input format and output format respectively - where
2265 format is one of "marc", "marcxml", "line", "marcxchange".
2267 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2268 does not print anything except warnings for records.
2270 For yaz-marcdump, added support for MARC split into files (-s) with a given
2273 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2274 spec, at http://www.loc.gov/standards/sru/record-update/
2275 This has changed the binary layout of the following structs:
2276 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2277 bend_update_rr . Patch by Ko van der Sloot.
2279 Added GFS utility function bend_assoc_is_alive which returns 1 if
2280 association is still alive (client is connected); 0 otherwise (client
2281 closed connection). This allows busy servers to stop working for
2284 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2285 been a separate piece of software. This version of ziffy has been modified
2286 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2288 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2290 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2291 Client code may now interrogate options such as "init_opt_sort" to
2292 find out whether the server claims to support various options.
2294 --- 2.1.40 2006/11/27
2296 Added utilities yaz_{set,get}_esn to set/get element set name from
2299 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2300 of YAZ and has been so since YAZ 2.1.10.
2302 Implemented ZOOM_record_error which returns error information for
2303 record (surrogate diagnostic).
2305 --- 2.1.38 2006/10/31
2307 Updates for SRU Update by Ko van der Sloot:
2308 1. Changed name from "operation" to "action"
2309 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2310 versions in the code, marked as 'backward compatible'.
2311 3. Added diagnostics for SRU Update.
2313 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2315 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2317 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2319 For GFS, fixed problem with SRU diagnostic 'First record position out of
2320 range' being issued for 0 hits.
2322 zoomtst10 part of Windows Build.
2324 --- 2.1.36 2006/10/13
2326 Implemented yaz_filepath_comp which splits a path into file path
2327 components (required by Zebra 2.0.3+).
2329 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2330 BSD inspired license until now so this should not have any real impact on
2331 anybody. See http://www.opensource.org/licenses/bsd-license.php
2333 Fixed bug #687: Missing log lines.
2335 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2338 Fixed bug #689: SRU diagnostics to be added.
2340 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2341 whether a connection is idle (no more work do do).
2343 --- 2.1.34 2006/10/04
2345 Change type of optval from long to int for invocation of setsockopt with
2346 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2348 Added support for specifying the max log file size for the Generic
2349 Frontend Server. The size is given with option -r.
2351 --- 2.1.32 2006/09/21
2353 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2355 --- 2.1.30 2006/09/17
2357 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2360 Fixed bug in Generic Frontend Server that could cause a server to stop
2361 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2363 For the generic frontend server, the maximum record size is used as maximum
2364 size of incoming packages (SRU + Z39.50). The value until was previously
2365 only used in Z39.50 Init negotiation and, later, in a session controlled
2366 sizes of records returned. This is controlled using -k option. It can be
2367 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2369 --- 2.1.28 2006/09/04
2371 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2374 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2376 New option for yaz-marcdump -lpos=value which allows setting a portion
2377 of MARC header to a certain value.
2379 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2381 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2382 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2384 --- 2.1.26 2006/08/15
2386 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2389 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2391 --- 2.1.24 2006/08/08
2393 Fixed MARC ISO2709 encoding routines to deal with character set
2396 Minor changes to GFS logging. Database included in search request log
2399 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2400 cached/multiple records.
2402 Shared libraries are built by default on Unix+configure.
2404 Changed cql2pqf transformation to use a different evaluation order. The
2405 new order is: always, relation, structure, position, truncation, index
2406 and relationModifier. Old order was: always, relation, relationModifier,
2407 structure, index, position, truncation. Note that the the latter ones
2408 override former ones for identical attributes.. The new scheme means that
2409 it is possible to override any existing attribute with a relationModifier.
2410 And also that it is possible to override everything for the index rule
2411 (except the ones listed in relationModifier). No order is perfect but this
2412 one, we believe, covers more real cases.. The "always" should have been
2413 called "default", since the attributes there can be overridden with all
2416 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2417 compilation phase, but also for yaz-config --cflags output. This allows
2418 us to have public headers with Libxml2 stuff in them . It should also,
2419 eventually, make Libxml2 checks redundant in packages using YAZ, such
2422 --- 2.1.22 2006/06/15
2424 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2425 stored in uri, message and details.. Previously diagnostics were stored
2426 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2427 compatibility.. but he's probably the only one affected, so.
2429 Added support for CCL, compiled on the client side, in ZOOM-C. This
2430 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2431 input; the resulting query objects can be used for for searching with
2432 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2434 YAZ' configure searches for OpenSSL by default.
2436 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2437 SL_CTX_use_certificate_file. See
2438 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2439 for more info. Thanks to Ko van der Sloot.
2441 --- 2.1.20 2006/06/02
2443 Bug #600: SRU GET, POST support for yaz-client. Introduced
2444 command 'sru' which selects method SOAP/GET/POST.
2446 Allow missingValueAction to be specified for the sortspec string -
2447 function yaz_sort_spec. By default, the missing value action is null.
2448 Use ! to specify "abort". Use = followed by stringvalue to specify default
2451 Ensured that Present-handler (if defined) is called in GFS before any call to
2452 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2453 searchRetrieve requests.
2455 Documentation for YAZ is now based on the Docbook XML/XSLT using
2456 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2457 is no longer depending on jade/openjade or docbook-to-man scripts.
2458 PDF is no longer part of the distribution - but can optionally be
2459 made using DSSSL/jadetex or FOP.
2461 Added retrieval handling support in Generic Frontend Server to support
2462 conversion between MARC/XML as well as XSLTtransforms. See
2463 etc/yazgfs.xml for an example.
2465 Added Authentication support to Generic Frontend Server in SRU
2466 mode. Authentication using HTTP Basic is supported, as is the use
2467 of 'x-username' and 'x-password' parameters in the request itself.
2469 Added support for a new character set MARC8s identical to MARC8 except
2470 that it converts combined characters to single Unicode characters in the
2471 Latin-1 range (when possible).
2473 --- 2.1.18 2006/04/24
2475 ASN.1 compiler 0.4: generates brief Doxygen file header for
2476 generated .h/.c files.
2478 Utility yaz_iconv now supports conversion to MARC-8.
2480 New facilities for the MARC module. The reading - and writing of
2481 content are separate methods for the yaz_marc_t handle. The following
2482 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2483 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2484 format). Write functions have prefix yaz_marc_write_.. The existing
2485 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2486 available. Removed support for OAI-MARC and simplexml (not the
2487 simplexml from PHP5).
2489 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2490 to be returned for this connection.
2492 --- 2.1.16 2006/03/31
2494 Allow multiple languages and charsets to be specified with
2495 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2496 negcharset iso-8859-1,utf-8
2498 Translation of proximity nodes from CQL into PQF now works.
2500 Moved to automake 1.8, 1.9.
2502 Added function yaz_log_set_handler which allows a log handler to be
2503 installed. This handler will be called for all log messages. Output
2504 to file is also produced; but that can be disabled by passing NULL
2505 fname to yaz_log_init_file.
2507 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2509 For SRW (including GFS), accept application/soap+xml as content-type
2512 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2513 produces NO stylesheet reference even if a default stylesheet is specified
2516 --- 2.1.14 2006/03/14
2518 Updated Windows package to include yazd.dll + yazd.lib for the
2519 Development component.
2521 If the environment variable YAZ_LOG is set, then it is used as a
2522 string indicating the default level of logging to use if not
2523 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2524 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2525 used as before. So, for example, to omit warnings from YAZ logging,
2526 export YAZ_LOG=-warn
2528 cql_transform() now map structure and other attributes before indexes,
2529 so that index-specific structures and other attributes can override
2530 defaults. So now a combination of mapping specifications such as:
2532 index.dc.date = 1=date-modified 4=5
2533 does the right thing.
2535 cql_transform() now also respects the "always" mapping specification,
2536 which establishes an initial set of attributes to be used for all
2537 terms except where overridden by more specific attributes associated
2538 with the index, relation or modifier.
2540 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2541 which mode to use; one of "post", "get" or "soap" (SRW, default).
2543 Fixes for yaz_iconv routines: changed trie-based character set conversions
2544 to use only non-negative values for bit fields due to Sun's C compiler not
2545 supporting negative values.
2547 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2548 sequences where not read correctly. Fix by Rustam Usmanov.
2550 Updated win/makefile to use options, settings which makes things
2551 compile with VS C 2005.
2553 --- 2.1.12 2006/02/01
2555 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2557 In ZOOM socket code, use select instead of poll on MacOSX.
2559 ZOOM-C now support client-side compilation of CQL into RPN that is
2560 sent to the server, enabling CQL to be used against all Z39.50
2561 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2562 ZOOM_query object, and submit it using ZOOM_connection_search().
2563 The CQL-to-RPN translation uses a configuration file, the name of
2564 which must be specified in the Connection's "cqlfile" option.
2566 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2567 function, which takes as its start-term parameter a ZOOM_query object
2568 (which may have had either CQL or RPN set into it).
2571 --- 2.1.10 2005/11/29
2573 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2574 GFS to support this as well. Backend handler, bend_srw_update, does the
2575 update work. Code contributed by Ko van der Sloot.
2577 Allow retrieval of Search Result-1 information in ZOOM by the use of
2578 options that are attached to a result set. ZOOM documentation updated
2581 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2582 UTF-8 conversion. Patch by Raj Patel.
2584 Added option -m to GFS to control formatting of timestamps in log file.
2586 Added 'exit' as synonym for 'quit' in yaz-client
2588 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2589 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2590 for the new members. Patch by Ko van der Sloot.
2592 Added support for SRU POST. It is supported for content-type
2593 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2595 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2596 Instead make the library libyaz.la multi-threaded. Threading as a whole
2597 can still be disabled by configure option --disable-threads. Previosly,
2598 with older GLIBCs there were problems with MT libs under Apache. This
2599 has now been fixed a long time ago.
2601 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2604 CQL module modified to be case insensitive for relations/indexes/operations.
2606 Fixed bug in CQL transform code: incorrect value relationModifieder
2609 Added 'show all' command for yaz-client which retrieves all results
2612 Added new yaz-client, xmles, which takes a (private) OID and
2613 a document to be sent as an extended service request.
2615 Describe new yaz-client commands wait_response and set_auto_wait.
2617 Increase TCP/IP listener backlog from 3 (which I am guessing was
2618 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2619 that the socket will queue as many incoming connections as it's able
2620 to handle ongoing connections. In other words, it will never now
2621 refuse a connection that it would be able to handle merely because
2622 it's not got around to accepting() enough of the pending connections
2623 yet. This is the behaviour anyway under Linux, where the listen()
2624 argument is ignored; but not under BSD and on systems such as
2625 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2626 YAZ-based servers should now be uniform across operating systems in
2629 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2630 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2631 This allows yaz-marcdump to read large MARC batches (>2 GB).
2633 Modified all YAZ source files - except the source which is auto-generated
2634 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2637 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2638 corresponding to the existing *_setl() function. These allow option
2639 values containing arbitrary valuues.
2641 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2642 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2643 except that it returns an indicator of whether or not the sort
2644 criterion was accepted (0 for OK, -1 for invalid).
2646 --- 2.1.8 2005/06/07
2648 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2649 MARC output rather than returning "new" buffer.
2651 yaz-client warns about unknown init options.
2653 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2655 --- 2.1.6 2005/05/24
2657 Added support for SRW sort in Generic Frontend Server. Patch
2658 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2659 sortKeys - or NULL if none is provided.
2661 Fixed bug #307: It was impossible to specify indefinite/no timeout
2662 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2665 Added support for multiple languages and charsets to be specified in
2666 ZOOM. Each charset/language is separated by a blank. If negotiation is
2667 in effect in init-response, Option
2668 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2669 Code based on patch by Vasiliy Osadchuk.
2671 Fixed bug #306: infinite recursion that occurred when calling
2672 yaz_log_level_init as the first call (before other log level or
2675 Fixed bug in scan handling in front end server: if preferred-Position-In-
2676 Response was non-present, a NULL pointer referece was performed.
2678 --- 2.1.4 2005/04/26
2680 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2681 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2682 now defined for all those error codes. So instead of putting 109 in
2683 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2684 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2686 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2689 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2691 Program yaz-client now exits and produces an error message if multiple
2692 Z39.50 servers are specified on the command line (none or one allowed
2695 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2698 --- 2.1.2 2005/03/16
2700 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2702 Fixed bug #272: Preserve spacing for CCL terms.
2704 --- 2.1.0 2005/03/14
2706 Added support for virtual hosts and multiple backend servers for
2707 the YAZ frontend server. The configution is XML based and
2708 support specificition of CQL to RPN mappings and explain information.
2709 See section "Virtual Hosts" in the YAZ manual.
2711 Extended OPAC display utility. OPAC display utility renders
2712 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2713 to supplement yaz_marc_decode_wrbuf.
2715 Fixed a bug in MARC decoder that could caused it to crash for some
2716 invalid MARC records. More diagnostics and warnings where added in
2717 XML output (warnings, etc are stored in comments).
2719 --- 2.0.34 2005/02/08
2721 Fixes for UNIX domain sockets. Bug #261.
2723 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2725 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2726 Added yaz_marc_subfield_str which defines subfield lead string which is
2727 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2728 yaz_marc_endline_str which defines end of fields string used in
2729 YAZ_MARC_LINE format. Default string is newline.
2731 Experimental support for MarcXChange. This format can be produced
2732 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2733 http://www.bs.dk/standards/MarcXchange.xsd
2735 Added yaz-client commands scansize that sets maximum number of
2736 entries to be returned by scan.
2738 --- 2.0.32 2005/01/11
2740 Added support for SRW scan in yaz-client and Generic Frontend Server.
2742 * Added whereInList member to SRW Scan Term.
2744 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2746 Fixed NMEM system to return aligned blocks on the smallest boundaries
2747 that are suitably aligned for all possible types on the particular
2748 architecture YAZ is being built for.
2750 --- 2.0.30 2005/01/04
2752 Fixed numerious warnings that was issued with newer versions of GCC.
2754 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2755 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2758 Make YAZ Generic Frontend Server slightly faster.
2760 Enhance (and reduce) logging for Generic Frontend Server.
2762 Revert YAZ log system so that it flushes every write operation
2763 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2765 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2766 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2767 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2768 will effectively disable old definitions.
2770 --- 2.0.28 2004/11/09
2772 Added yaz_log_time_format which specifies log format using
2775 Added yaz_log_module_level which returns mask for a module. Value
2776 is non-zero mask a if module is enabled; zero if disabled.
2778 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2779 in include/yaz/cql.h.
2781 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2783 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2785 Fixed bug #172: RPM builds does not enable SSL.
2787 Doxyfile.in part of dist. Doxyfile generated by configure.
2789 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2790 are given and the corresponding component does not exist.
2792 Extend CCL documentation in YAZ reference. Describe r=r.
2794 --- 2.0.26 2004/10/01
2796 Fixed MARC->MARCXML conversion to properly deal with
2797 fields, subfields, indicators having non-ASCII characters.
2799 Fixed MARC->MARCXML conversion so that ASCII control characters
2800 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2803 Added YAZ GFS support for conversion from Z39.50 surrogate
2804 diagnostics to SRW surrogate diagnostics.
2806 Bug fix: YAZ GFS did not return schema in explainResponse.
2808 --- 2.0.25 2004/09/30
2810 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2811 now converts recordSchema to elementSetName as well as schema URI.
2813 Fixed bug in COMSTACK that prevented HTTP request packages from being
2816 --- 2.0.24 2004/09/29
2818 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2819 does not require white-space before and after the dash in a range, e.g.
2820 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2823 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2824 due to new GCC removing "redundant" code.
2826 Added yaz-client commands scanpos and scanstep that sets preferred
2827 position and step-size for scan.
2829 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2831 Added CCL utility ccl_qual_buf which parses one or more CCL
2832 spec lines in a buffer.
2834 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2835 of name and value - ignoring empty lines and comments.
2837 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2839 Added odr_get_element_path which returns current element path for an
2840 ODR handle. This utility is useful in error handling or user-defined
2843 Added ODR_PRINT utility odr_set_stream which is is a more generic
2844 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2845 to a write function and pointer to close function. The close function - if
2846 non-NULL - will be called during odr_destroy.
2848 Fixed bug in CCL parser where truncation char was not removed from
2849 right side when truncation=both was in effect.
2851 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2854 --- 2.0.23 2004/08/11
2856 Fix buffer overrun in CQL parser when dealing with proximity (%).
2858 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2859 to UTF-8/UCS conversion is now only based on codetables.xml.
2861 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2863 --- 2.0.22 2004/08/06
2865 Add support for more "commit changes" in ZOOM (uses Extended Services).
2867 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2870 Yet another small fix for configure of SSL.
2872 --- 2.0.21 2004/05/14
2874 Fix SSL libs for configure when --with-openssl=DIR is given.
2876 --- 2.0.20 2004/05/10
2878 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2880 SSL comstack now uses yaz.pem certificate file on server side
2881 by default. Certificate filename can be configured by calling
2882 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2884 Fix bug regarding multiple calls to ZOOM_connection_connect.
2886 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2888 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2889 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2891 ZOOM now allows inspection of X509 peer certificate for verification.
2892 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2894 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2895 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2896 as "modular" but it simplifies things.
2898 Added cs_get_peer_certificate to that returns peer X509 PEM.
2900 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2901 NULL if SSL is unavailable.
2903 Documentation about MARC decoding tools.
2905 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2907 --- 2.0.19 2004/03/30
2909 Rename CHANGELOG to NEWS to follow GNU style packing.
2911 Fix bug with missing initialization of member in init_diagnostics.
2912 This bug affects threaded version of GFS server.
2914 --- 2.0.18 2004/03/20
2916 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2919 Ensure zlib.dll is packed with Windows install.
2921 --- 2.0.17 2004/03/17
2923 Fix encoding of xsd:string to use text instead of CDATA.
2925 Fix endless loop in CQL parser with unbalanced ".
2927 Use a more compact way to store MARC-8 conversion tables.
2929 --- 2.0.16 2004/03/16 Debian only
2931 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2934 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2939 --- 2.0.15 2004/03/01
2941 Another fix for decoding of XML packed records.
2943 --- 2.0.14 2004/02/25
2945 Fixes for Chunked encoding. White space not ignored after length spec.
2947 Update NS and use default NS for SRW diagnostic elements.
2949 --- 2.0.13 2004/02/23
2951 Implement ZOOM_resultset_cache_reset which resets record cache.
2953 Implement ZOOM_resultset_sort which sorts a result set.
2955 Implement chunked HTTP transfer.
2957 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2959 --- 2.0.12 2004/02/16
2961 Added member 'schema' to bend_explain_rr structure so that backend
2962 can specify explain record identifier. Defaults to Zeerex 2.0.
2964 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2966 --- 2.0.11 2004/02/16
2968 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2971 Added init command for yaz-client which sends "extra" init request.
2973 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2974 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2976 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2978 Make ZOOM error code for "invalid query".
2980 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2982 --- 2.0.10 2004/02/05
2984 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2987 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2989 Added option -p <file> to make Generic Frontend Server to write PID file.
2991 Added option -D to put Generic Frontend Server in background on its own.
2993 Make ZOOM C recognize option "password". If unset, "pass" is used
2994 (for backwards compatibility).
2996 Fixed a bug in Generic Frontend Server that could make it crash if a
2997 client sets characterSetNegotation bit, but didn't pass negotiation stuff
3000 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
3001 Must be issued before open, in order to be in effect.
3003 --- 2.0.9-6 2004/01/12 Debian/Windows
3005 Make the SRU server more picky WRT unknown params, etc.
3007 Bug fix: ZOOM scan response didn't return displayTerm - when present.
3009 New YAZ client command, options, that sets Z39.50 options.
3011 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
3012 options from a string of tokens (one token for each option bit).
3014 Update SRW diagnostic code messages.
3016 --- 2.0.9-5 2004/01/07 Debian/Windows
3018 Handle user defined stylesheet for SRW/SRU.
3020 --- 2.0.9-4 2004/01/06 Debian/Windows
3022 Fix bug in decoding of Content-Length.
3024 --- 2.0.9-3 2004/01/06 Debian/Windows
3026 Fix a bug with decoding of XML packed records.
3028 --- 2.0.9-2 2004/01/05 Debian only
3030 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
3032 Fix bug in SRW/SRU diagnostics decoding.
3034 --- 2.0.9 2004/01/05
3036 Fixed bug in Generic Frontend Server which could drop records exceeding
3037 preferred message size. Reported and fixed by Irina Dijour.
3039 Fixed calculation of package size for structured records in Generic
3040 Frontend Server. Reported and fixed by Irina Dijour.
3042 Fixed namespace for SRW/SRU diagnostics.
3044 Fixed SEGV in yaz-client that occured for HTTP connection errors.
3046 --- 2.0.8 2003/12/22
3048 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
3049 this version is incompatible with version 1.0 and older YAZ SRW/SRU
3052 CQL changes to reflect recent changes to the specification:
3053 * Documentation talks about context sets instead of index sets.
3054 * Documentation talks about indexes instead of qualifiers.
3055 * The CQL-to-PQF transformer's configuration file now uses
3056 "index.set.name = <attributes>" instead of the old form
3057 "qualifier.set.name = <attributes>". (Both forms are still
3058 understood but the latter is deprecated.)
3059 * CQL terms with no explicit index specified are now interpreted as
3060 cql.serverChoice instead of srw.serverChoice (which of course
3061 behaves exactly the same.)
3063 --- 2.0.7 2003/12/16
3065 MARC conversion can now generate ISO2709 output in another
3066 character set. yaz-marcdump uses this facility if you invoke it
3069 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
3070 functions from there can be used from C++.
3072 --- 2.0.6 2003/12/04
3074 Frontend server now transfers memory from decoded packages to stream
3077 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
3078 references to show up.
3080 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
3081 the ZOOM Abstract API. The older names for the same options are still
3082 also supported for the benefit of old applications.
3084 ZOOM-C supports "implementationId" and "implementationVersion" options
3085 to go along with "implementationName". These allow the user code to
3086 specify identification strings to be sent to servers.
3087 Add OID for the new ExtLite attribute set.
3089 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
3090 as requested/supplid by Ere Maijala <ere@atp.fi>
3092 For generic frontend server, reverse the order of
3093 "toolkit-supplied / application-supplied" strings sent as implementationId,
3094 Name and Version. Also, remove the spaces around the slash. This brings
3095 the GFS in line with the behaviour of ZOOM-C on the client side.
3097 Add function ZOOM_scanset_display_term.
3099 yaz-client shows scan displayTerm if present.
3101 Utility yaz-iconv is now installed by default along with the man page
3104 Extend configure check for OpenSSL to use pkg-config where available (such
3107 Incorporate patch by Morten Bogeskov which allows a Unix file socket
3108 server to specify uid/gid/mask for socket using the format
3109 unix:[user=uid,][group=gid,][umask=mask,]file=path
3110 If file= is omitted the existing format is assumed, e.g.
3112 in which case the mask is 0666 (rw for everybody).
3114 Major restructure of YAZ source. All source in libyaz is in src directory.
3115 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
3116 util (utility programs such as ASN.1 compiler, yaz-marcdump).
3118 Added man page for utility yaz-marcdump (used to be called marcdump).
3119 yaz-marcdump is installed by 'make install'.
3121 Fixed a memory leak in Generic Frontend Server that occurred when decoding
3122 of incoming package failed.
3124 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
3126 Change prototype of odr_perror: add const to message string.
3128 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
3130 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
3131 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3132 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3133 DNS lookup. There should not be any compatibility problems with this
3134 assuming that blocking=1 or 0 is used.
3136 Fix bad reference in UNIX comstack in function cs_addrstr.
3138 Fix for compilation on AIX.
3140 The generic front-end server (server/seshigh.c) now supports returning
3141 Init diagnostics to the client in User-information-field, in
3142 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3145 --- 2.0.4 2003/09/04
3147 Allow any CQL relation (not just all,any,exact,scr).
3149 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3150 that features the same UI.
3152 Implemented command update0 in YAZ client which is equivalent to
3153 update but uses old of Ext Update ASN.1.
3155 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3156 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3157 Previously no OID was used for this info.
3159 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3160 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3161 returns 'malformed search term' otherwise.
3163 SortResponse member resultCount now set to NULL in sort handler of
3166 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3169 Add three new utility functions for translating OIDs between various
3170 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3171 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3172 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3173 char *oid_to_dotstring(const int *oid, char *oidbuf);
3174 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3176 Reverted modifications for ES Update definition for z_IU0Update
3177 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3178 is back to YAZ 2.0.2.
3180 String value attributes for CCL parser.
3182 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3183 which their FirstSearch server returns in Init responses, sometimes
3184 carrying useful diagnostic information when Init fails. This has the
3185 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3186 "z39.50/oclcui.asn", where its definition is somewhat different from
3187 what OCLC document on their web-site, as required to interoperate with
3190 Support for anonymous authentication in yaz-client. Use the command
3193 * Fix the OID of the Index Data-local "admin" Extended Service from
3194 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3195 the 1000, which indicates a locally-defined OID, was a mistake.
3197 --- 2.0.3 2003/06/20
3199 Fix CCL directive @case handling so that it affects string match for
3200 both CCL keywords and qualifiers.
3202 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3203 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3204 Decoder has been updated with ASN.1 changes as listed in
3205 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3206 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3207 z_IUUpdate, remains unchanged.
3209 ZOOM_record_get may now return a record in a specific character set.
3210 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3211 "from" is the character set of record as returned by target. "to" is
3212 the character set to be returned. If omitted, "to" is UTF-8.
3214 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3216 New ODR utility, odr_getelement, which returns name of element for
3217 which encoding/decoding failed.
3219 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3220 in cases where a required element was omitted.
3222 Bug fix: some MARC8 sequences were not converted.
3224 New ZOOM option "step" which specifies number of records to be
3225 retrieved in one chunk. Used in conjunction with "start" and "count".
3227 SRW support for yaz-client. Use scheme http: to use it, e.g.
3230 yaz-client no longer does (un)intelligent character set conversions
3231 by default. Can be enabled with charset and marc_charset commands.
3233 xmalloc trace fix for 64-bit systems such as DEC alpha.
3235 Solaris 2.6 compile fix.
3237 New function, cql_strerror() translates SRW error codes, as returned
3238 by cql_transform_error(), into human-readable English strings. Used
3239 in yaz-client diagnostics when appropriate.
3241 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3242 converts it into a type-1 query which is sent to the server. This
3243 makes CQL available for use with all Z-servers, as opposed to the tiny
3244 minority that can handle CQL queries themselves.
3246 --- 2.0.2 2003/04/28
3248 New Debian package layout similar to the Redhat Package layout.
3250 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3251 and search result respectively.
3253 --- 2.0.1 2003/04/25
3255 Redhat package is now several packages: libyaz (runtime libraries),
3256 libyaz-devel (development and documentation, and yaz (utility programs).
3257 Package spec file by Morten Bogeskov.
3259 New member 'schema' in struct bend_fetch_rr which the name of requested
3260 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3261 handler MAY set this to reflect the schema of the returned record.
3263 New member 'display_term' in struct scan_entry. GFS now sets member entries
3264 and allocates scan entries to be filled by user scan handler. In previous
3265 version, entries member was allocated by the scan handler. That still works,
3266 but the GFS will ignore member display_term - assuming it was NOT set by
3267 the handler. The fact that the GFS now allocates the entries both allows
3268 for new members and makes a scan handler easier to write.
3270 Fix CQL lex buffer overflow.
3272 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3273 SRU default recordPacking is string.
3275 SRU protocol support for frontend server.
3277 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3279 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3281 Added scan for the ZOOM shell (zoomsh).
3285 * String Identifers for Schemas (Amendment 5).
3286 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3287 Old definition for schema
3288 Odr_oid *schema; /* OPT */
3293 Z_InternationalString *uri;
3294 #define Z_Schema_oid 1
3295 #define Z_Schema_uri 2
3298 * resultCount parameter to Sort Response (Amendment 1).
3299 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3301 Support for SRW 1.0 over HTTP. This is an optional feature and
3302 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3305 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3306 on the same port. SRW SearchRetrieveRequests are mapped
3307 to bend_init,bend_search,bend_fetch,bend_close.
3309 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3311 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3312 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3314 ZOOM connections are SRW based if schem http is used for hostname
3315 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3316 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3318 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3319 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3320 distance=n, order=true/false, relation=le, prox unit=word. If
3321 n is omitted, distance 1 is used.
3323 Fixed problem with C compiler include path in wrong order.
3325 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3326 on Solaris. Patch from Ko van der Sloot.
3328 New MARC decode API. All new functions operate on a yaz_marc_t
3329 handle. The most important new functions are: yaz_marc_create,
3330 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3331 decode and destroy respectively. Decoder can produce formats
3332 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3333 include/yaz/marcdisp.h.
3335 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3336 to UTF-8, UCS-32, wchar_t or Latin-1.
3338 * Prototypes for yaz_iconv_-functions moved to separate header
3339 include/yaz/yaz-iconv.h.
3341 Make a few private functions 'static' in unix.c. This prevents
3342 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3344 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3345 are set when Init Response is received.
3347 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3348 but returns diagnostic set as well.
3350 New function yaz_strerror which is a portable wrapper for
3351 strerror/strerror_r/GetLastMessage.
3353 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3354 is returned for MARC. If type is "oai", then OAI MARC is returned.
3356 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3359 --- 1.9.2 2002/11/26
3361 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3363 Fix bad race conditions on SIGTERM and terminate gracefully in
3366 Move retrieval (data1) module to Zebra since nobody seems to be
3369 Add GRS-1 render for ZOOM using same format as yaz-client.
3371 --- 1.9.1 2002/10/05
3373 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3375 Fix broken ESpec handling in data1 module.
3377 SGML reader parses comments and makes them part of the data1 tree.
3379 Added several type casts so that YAZ compiles as C++ code.
3381 ZOOM didn't handle PDU encoding failures properly.
3383 Added more Bib-1 diagnostics (approved extensions).
3385 GNU configure: better check for iconv.
3387 More portable use of accept, getpeername. Check for socklen_t. Use
3388 int/size_t if socklen_t is not defined.
3392 PQF parser rejects bad queries - including those with extra
3393 characters in them. PQF parser used to silently ignore that.
3394 Cleaner API for PQF added, which allows you to get detailed
3395 error information for bad queries (see yaz/pquery.h).
3397 Fixed bug in ZOOM_record_get for type "database".
3399 Implemented mini iconv library supporting conversions between
3400 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3402 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3404 --- 1.8.9 2002/08/20
3406 Fixed ZOOM C record cache so that preferredRecordSyntax and
3407 elementSetName is used to check for already fetched records.
3409 --- 1.8.8 2002/08/02
3411 Added three members in bend_initrequest structure to facilitate
3412 character set negotiation.
3414 Fixed a bug in frontend server that could cause indefinite
3415 loops under rare conditions.
3417 Revised character set utilities (charneg.h) so that encoding
3418 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3420 For PQF, directive @term <type> sets term type for Scan/Search.
3421 Here <type> is general, string, numeric, null. The term type
3422 is inherited - just like @attr.
3424 New call odr_set_charset that sets character set conversion for
3425 international-strings on a ODR stream. Prototype is:
3426 int odr_set_charset(ODR o, const char *to, const char *from);
3427 The InternationalString is still represented as C string in YAZ
3428 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3429 won't). On the protocol level, you can use any encoding.
3431 Support for UNIX sockets in ZOOM.
3433 Solaris recv sometimes returns errno == ENOENT. It is treated as
3434 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3436 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3437 both client and server. Code by Morten Bogeskov.
3439 --- 1.8.7 2002/05/22
3441 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3442 that they can be used directly from Visual Basic. You must recompile
3443 your windows APP if you're using ZOOM.
3445 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3446 Commands "lang" and "charset" sets language and character set respectively.
3447 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3448 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3450 Attributes from multiple CCL fields may be OR'ed rather than merged
3451 using directive "@field or". Fields are still merged by default -
3452 equivalent to "@field merge".
3454 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3457 Fixed bug in zget for parameter ExtendedServicesResponse.
3461 --- 1.8.6 2002/03/25
3463 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3465 Client displays USR.1:SearchResult-1 (hits per term).
3467 Additional Search Info for search in Generic Frontend Server.
3469 Fixed CCL parsing of "field=s".
3471 WIN32 installer - using the excellent NSIS software from nullsoft.
3473 Fixed CCL parsing of "field = - <number>".
3475 Added function yaz_marc_decode that decodes MARC for line mode
3476 display or XML (similar to that used by JZKit).
3478 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3479 Z39.50. But ISO/ILL was, however.
3481 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3482 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3484 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3485 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3487 --- 1.8.5 2002/02/03
3489 New YAZ client features: Command completion and new commands:
3490 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3491 Code provided by Jacob Poulsen.
3493 New call oid_trav, that visits all registered OIDs via callback.
3495 Function ZOOM_record_get now returns const char pointer rather than
3496 void pointer. It saves a lot of type casts.
3498 For YAZ client, command "auth" now allows you to set authentication
3499 in IdPass style. It is enabled when three tokens are given - order
3500 is user, group and password.
3502 Fix memory leaks in MARC record handling for ZOOM.
3504 New option for YAZ client, -k <kilobytes> that sets
3505 maximum record size. Similar to -k option for generic frontend
3506 server and yaz-ztest.
3508 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3510 Prefix query parser reports "fail" when bad attribute set is given.
3512 Fix in MARC decoder. Proximity logging. Fix for attribute set
3513 in scan handler for server. Patches by Shigeru Ishida.
3515 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3518 Configure option --with-openssl=<dir> now works when a directory is
3519 specified. Patch provided by Morten Bogeskov.
3521 New option for YAZ client, -u <auth>, that sets authentication.
3523 ZOOM fix: error information was sometimes "missing", since error
3524 was cleared/reset too when it shouldn't.
3526 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3528 --- 1.8.4 2002/01/04
3530 Scan for ZOOM API. New object ZOOM_scanset. New functions
3531 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3532 ZOOM_scanset_destroy.
3534 New ZOOM function, ZOOM_connection_last_event, that returns type
3535 of last event (such as "receive data", "send data", "apdu received",
3538 New ZOOM option, schema, that specifies schema for retrieval.
3540 New CCL feature. Qualifiers can be aliases for one or more
3541 other qualifiers (if more than one is given, OR is used).
3543 ZOOM uses named result sets if target supports it.
3545 Two new YAZ client commands: . (dot, which sources a script of YAZ
3546 client commands), and ! (to execute shell command.). Implemented
3549 Working on Debian packages.
3551 --- 1.8.3 2001/11/19
3553 YAZ client enables named result sets only if target supports it.
3555 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3557 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3558 with key="host" to get same result.
3560 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3561 Function Z3950_resultset_record(s) returns references to records
3562 "owned" by resultset. To become owner use Z3950_record_clone.
3564 Function z_ext_record handles Extended Services. Thanks to
3567 --- 1.8.2 2001/11/12
3569 CCL Parser fix: ignore token comma when dealing with and-lists.
3571 Documentation updates for COMSTACK.
3573 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3574 Changed prototype Z3950_records. For some functions, int parameters
3575 were changed to size_t.
3577 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3580 New MARC decode/display function, marc_display_exl, which properly rejects
3581 non-ISO2709 records. YAZ client uses it.
3583 --- 1.8.1 2001/10/29
3585 Fix bug: local attribute set wasn't set correctly in PQF strings.
3589 * Old Z39.50 codecs no longer supported.
3591 Added ZOOM C binding. See http://zoom.z3950.org/
3593 Renamed states for COMSTACKs to avoid confusion with events.
3595 Implemented cs_look and proper cs_rcvconnect.
3597 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3599 Configure detects POSIX threads on OpenBSD.
3601 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3602 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3604 When error is returned from present handler, non-surrogate diagnostic
3605 is returned in present response (and fetch handler is no longer called).
3607 * Minor adjustments to pquery parser (PQF). Token characters may be
3608 escaped by using backslash (C-style).
3610 PQF parser allows string attribute values to be specified. For @attr,
3611 non-numeric characters after the equal-sign are treated as strings
3612 (e.g. @attr 9=title).
3614 CCL trunction character may be defined (@truncation in file)
3616 * function zget_ExtendedServicesRequest sets waitAction to
3617 waitIfPossible (was wait).
3619 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3622 CCL operator names may be set in field definition files (CCL_bibset).
3623 See ccl/bib1 for an example.
3625 Fixes in ASN.1 compiler for C++ compatibility.
3627 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3628 and "op_or" to avoid conflict with C++.
3630 Fixed problem with GNU readline detection on Redhat 7.0.
3632 Added step-size for Scan backend handler.
3634 Fixed bug that made the frontend server crash when no attribute
3635 set was specified for scan.
3637 Front-end server automatically switches to original working directory
3638 when installed as an NT service. Previously -w had to be specified to
3641 Added extended attributes for retrieval module (data1), so that data1
3642 records carry d1_readXML/SGML attributes. d1_read also supports
3643 null-data rules ( <tag/>)
3645 On UNIX when POSIX threads are available, a separate library libyazthread
3646 is created. Programmers should link with that library and the yaz library
3647 when using threads. The reason for the split was that some applications
3648 on Linux, such as Apache, doesn't work well when using shared objects that
3651 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3652 (or any frontend server) in SSL mode by specifying ssl: followed by
3653 address. Only tested on UNIX.
3655 Added feature for CCL module. Virtual structure s=al or s=ol generates
3656 and-list and or-list respectively instead of phrase search.
3660 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3661 log_mask_str. This was done to avoid name conflicts with other libraries
3662 (such as other PHP extensions).
3664 Added raw OID member for preferred record syntax (request_format_raw)
3665 and returned record syntax (output_format_raw) for backend fetch method.
3667 Config file yaz-config now accepts options so that it returns specific
3668 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3670 Shared library support for UNIX using GNU libtool.
3672 * Modified backend interface. Request/Response struct's replaced by
3673 one read/write C struct. For example bend_fetchrequest and
3674 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3675 Every handler - even search has to be registered in bend_init
3676 handler. This means that the YAZ library no longer refers to
3677 external functions and it makes it possible to make the whole
3678 thing a single DLL/SO.
3680 Added Segment handler for backend server.
3682 Added Zmbol/Zebra administrative functions to YAZ client.
3684 Threaded frontend server on UNIX (when POSIX Threads are available).
3685 Starting the server with option -T enables multi-threading.
3689 Added configure option --enable-comp/disable-comp to control use
3690 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3691 located in sub directory asn.
3693 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3694 in ${exec_prefix}/bin along with the other programs yaz-client and
3697 GNU automake used to maintain makefiles.
3699 Added several OID's.
3701 Changed retrieval module so that we can load records with no abstract
3702 syntax defined. Tagpaths in these records are fully composed of string
3705 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3709 On UNIX, the generated makefile now supports a proper 'make install'.
3710 The prefix can be set via GNU configure to set the install location
3711 (default is /usr/local).
3713 * YAZ programs client and ztest were renamed to yaz-client and
3714 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3715 locations, such as /usr/bin,/usr/local/bin,etc.
3717 * YAZ Header files were moved from include to include/yaz. YAZ Header
3718 files are referred to as include <yaz/log.h> rather than <log.h>.
3719 The YAZ include path (-I ..) is therefore the same as before. Programmers
3720 should update their #include statements or use -Ipath/include/yaz
3721 instead. The main motivation for doing this change is that YAZ header files
3722 can be installed in "standard" locations /usr/include,/usr/local/include
3723 without introducing conflicts, since ALL YAZ header files are stored
3724 in subdirectory yaz (under /usr/include for example).
3726 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3727 rather than project/workspace files. We switched because project files
3728 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3731 Changed name of logging function, logf, to yaz_log, to prevent name
3732 clash with some math-log functions. The YAZ header log.h defines logf
3733 to yaz_log (#define) so there should be no incompatibilities by this
3736 Added bend_start/bend_stop handlers for server. These handler are
3737 called on start/stop of server. For windows they are called whenever
3738 a service is started/stopped.
3740 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3741 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3742 in util/yc.tcl. The auto-generated C code structures are, in a few
3743 cases, incompatible with the old decoders. There are differences in the
3744 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3745 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3746 The preprocessor variable ASN_COMPILED is defined when the compiled
3747 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3748 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3749 wish to use the old encoders/decoders you can specify --disable-yc
3752 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3753 version so that it supports both new - and old version of DB Update
3755 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3756 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3757 change. The name parameter can be set to 0 in which no name is specified
3758 for the construction. The macros odr_implicit and odr_explicit sets name
3759 parameter to zero for the construction involved. New macros
3760 odr_implicit_tag and odr_explicit_tag are similar to the others,
3761 except that a name parameter is added. For programmers' that don't use
3762 ODR they probably only need to change the call to z_APDU and z_External.
3764 Added access control facility by interfacing the TCP wrapper library.
3765 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3766 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3767 name of the daemon and enables the access control as specified in
3768 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3770 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3771 den Dool <H.M.vdnDool@kub.nl>.
3773 Added reference ID parameter to most functions in server API - refer
3774 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3776 Changed name of ccl library to libccl.a (was ccl.a).
3778 Fixed bug in decoder for Explain (Category TargetInfo).
3780 Added support for GNU readline in client. Thanks to Jacob Poulsen
3781 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3783 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3784 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3785 IMPLEMENTATION! This change was made to the development version before
3786 the ZIG decided to retract the amendment. If any users MUST be
3787 compatible with the original Update definition, PLEASE CONTACT US, and
3788 we will include a separate definition corresponding to the old Update
3789 ES. Note that because of the change to the ASN.1 of the
3790 TaskPackageRecordStructure we cannot define a single structure that
3791 will support both versions.
3793 * Added const modifier to buffer parameter for some ODR/BER encoding
3794 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3795 completeWAIS, odr_dumpBER.
3797 Fixed bug in client.c which caused a crash when a scanResponse didn't
3798 contain positionOfTerm.
3800 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3801 * will cause an error in a client if a non-YAZ target sends both a
3802 * list of Scan entries and non-surrogate diagnostics.
3804 Retrieval module enhancements. Tag sets may be typed in the reference
3805 to it. From the .abs-file the "tagset" directive takes a third optional
3806 integer type for the tag set referenced. From a .tag-file the "include"
3807 directive takes a third optional type as well. The old "type" directive
3808 in the tag set itself is still recognized but acts as the default type
3811 Backend interface change. Individual Scan terms returned from bend_scan
3812 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3813 in include/backend.h.
3815 Retrieval module enhancements. Multiple tag sets and attribute sets may
3816 be specified in abstract syntax specs. Revised the error/warning for
3817 logging messages reported by the retrieval module when reading the
3820 Object Identifier system (oid_..) changed. The API is backwards
3821 compatible but the oid-routines now allocates new OID's when needed.
3822 Raw OID's may be specified in oid_getvalbyname.
3824 YAZ now uses GNU configure to generate Makefile(s).
3826 * Minor changes in some of the member names of DeleteResultSetRequest and
3827 DeleteResultSetResponse. See include/proto.h.
3829 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3830 and added member 'languages' in TargetInfo (which was missing).
3832 Changed the way attribute sets are handled in the retrieval
3833 module. These are now cached, just like the abstract syntaxes
3836 Changed YAZ so that it links with compiled ASN.1.
3838 Added Explain-schema definitions and mapping routines. The following
3839 Explain categories have been implemented: AttributeDetails,
3840 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3842 Fixed minor bug in Windows version of Server Library.
3844 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3846 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3848 Added EXTERNAL: UNIverse Resource Report (non-standard).
3850 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3851 ENUMERATED and SET OF.
3853 * Added 'const' to some of the char pointer arguments for the
3854 functions, data1_read_node, data1_getelementbytagname,
3855 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3858 Fixed bug in data1_insert_taggeddata - the last_child member of
3859 parent wasn't initialised.
3861 * Changed data1_read_record and data1_read_node so that the supplied
3862 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3863 doesn't refer to any parts of the "SGML"-buffer.
3865 Fixed bug in server library (Windows version of statserv_remove).
3867 * Changed code so that it compiles as C++. The type definition
3868 of Odr_fun which is a member of Odr_arm was changed. The result is,
3869 that an explicit typecast is needed for the fun pointer when
3870 using Odr_arm - as in:
3871 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3873 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3875 Implemented the new structured date and time definition as approved
3876 by the ZIG. Added schemaId element to the specificTag in Espec-1
3877 (also approved at the last ZIG). Thanks to RVDM.
3879 Added some Object identifiers (RVDM).
3881 Changed the Update Extended Service (RVDM).
3883 Added command "refid" to client which specifies referenceId for
3884 the following requests.
3886 Implemented extended service handling for server. See ztest.c
3887 for an example as well as backend.h. New handlers are registerd
3888 in the Init handler.
3890 * Changed interface for sort in server.
3892 Added new members to statserv_options_block. It allows a server
3893 to read options from another source than just the command line. Thanks
3894 to Charles Woodfield.
3896 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3897 renamed to zboolean. Some C++ compilers complained about the name.
3899 Minor changes to gils.abs. Added index 's' (sort) on title
3900 and date/time-last-modified.
3902 --- 1.4pl2 1998/1/30
3904 Fixed bug in server library regarding inetd mode (-i). This bug
3905 was introduced by release 1.4.
3907 --- 1.4pl1 1998/1/29
3909 Added sort facility in client and backend server interface.
3911 Fixed problem with dependencies in Makefile(s).
3913 Fixed bugs for encoders/decoders of extended services and
3916 Implemented sub-tree feature for schemas. Sub-trees are
3917 referenced in *.abs-files. See explain.abs for an example
3918 of the use of this feature.
3920 Modified bib1.att; local attributes for ANY didn't include
3921 ANY itself (only affects use of the retrieval module).
3923 Fixed bug in plain SGML reader in function data1_read_node:
3924 tags with prefix "var" was incorrectly interpreted as variants.
3926 Added feature "sub-schemas" to enable references to - and definitions
3927 of - group of elements.
3929 * Removed member parent from type data1_element (in data1.h).
3931 Implemented function odr_nullval() that returns the value of
3934 * Removed member num_children from data1_node (in data1.h).
3936 Made NT service interface part of the server library. The
3937 function statserv_main uses the NT service when required and
3938 calls the statserv_start / statserv_close routines.
3940 Routine zget_SearchRequest and zget_PresentRequest fills
3941 resultSetName/Id member with "default" instead of "Default".
3943 Fixed memory leak in server. Request queue member wasn't freed.
3945 Fixed nmem_exit so that memory is freed.
3949 Revised the CCL parser utility to be thread safe.
3951 Added function, oid_ent_to_oid, to replace the function
3952 oid_getoidbyent, which is not thread safe.
3954 * Added nmem_init and nmem_exit to initialize and release
3955 NMEM resources. Function nmem_init should be called once in the
3956 initial thread before NMEM/ODR is used. statserv.c and client.c
3957 have been changed accordingly. The change was necessary to make
3958 NMEM thread safe. The NMEM memory pool is shared amongst threads
3959 in a process. Unix-based applications will still work fine without
3962 Added NT Services interface for the the Z39.50 (statserv) Server.
3963 Refer to the ztest.c source on the usage.
3965 Windows 95/NT port using MSVC5.0. Project files are included in the
3968 * Defined new 'global' handle for the retrieval (data1) system. The
3969 new handled, data1_handle, describes the state of the data1 system.
3970 This handle is passed as first argument to virtually all
3971 data1 related routines. The functions data1_create and data1_destroy
3972 creates and destroys a data1 handle respectively.
3974 Added ODR encode stream member to all backend request structures
3975 init, search, scan etc. This stream should be used to allocate all
3976 memory used for the response when thread safe operation is needed.
3978 Changed the comstack utility, cs_addstr, to be thread safe. The
3979 returned hostname string returned by the function is now part the
3982 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3983 function. The cs_straddr takes a COMSTACK handle as argument, so this
3984 function must be used after cs_create and before bind/connect.
3985 This function is thread safe.
3987 Moved test server to 'ztest' directory - generic server code still
3988 in 'server' directory.
3990 Made prefix query (pquery.c) utility thread safe.
3992 Added new function modifier YAZ_EXPORT to 'export' public DLL
3993 functions when using windows (see include/yconfig.h).
3995 Added definitions to the OID database (util/oid.c) (RVDM).
3997 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3999 Added call to ccl_rpn_delete in client program.
4001 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
4002 release of RPN structure.
4004 Added support for C++, headers uses extern "C" for public definitions.
4005 With input from RVDM.
4007 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
4008 Thanks to Ronald van der Meer (RVDM).
4010 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
4012 Added support for private extensions to the OID database
4013 (oid_setprivateoids()). Thanks to RVDM.
4015 Added optional, physical ANY (key replication)
4017 Fixed null-reference problem in GRS-1 output filter.
4019 Proximity operator added to Prefix Query Format (PQF).
4021 In test client command "base" accepts multiple databases.
4023 Fixed bug in cs_close stack that caused trouble with WINSOCK.
4027 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4029 Smallish bug-fixes in the new encoders/decoders (explain).
4031 Bug fixed in DeleteRequest.
4033 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
4035 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4037 Added SOIF syntax (using private OID for now) to retrieval module and client.
4039 Added Update extended service.
4041 Added SearchResult-1 additional info structure.
4043 Added optional CCL (ISO8777) interpreter as separate module. Available
4046 --- 1.2 1996/6/10 (1st anniversary release)
4048 Added Summary record syntax. Lightly tested.
4050 Added OPAC record syntax. Untested.
4052 Added ResourceReport service encoders/decoders. Untested.
4054 Fixed bug in z_Unit - wrong tagging on unitSystem.
4056 Fixed bug in the DiagRecs decoder.
4058 Added options for max PDU size and session timeout to frontend-server.
4060 Added documentation of query-language parsers and other supporting utilities.
4062 [frontend-server] Added Attribute set to the bend_scanrequest API.
4064 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
4065 surrogate diagnostics were generated.
4067 [retrieval] Allow multiple local values for attribute.
4069 [retrieval] Allow multiple attributes per element in .abs files. index type.
4071 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
4073 --- 1.1pl2 1996/4/10
4075 Minor changes, mostly specific to Zebra's requirements (retrieval)
4079 Repaired bug in frontend server when running multiple listening
4080 endpoints in dynamic mode.
4082 z_External() now won't break if a known, ASN.1 value comes encapsulated
4083 in an octet-string. The value will pass through unmodified in an Odr_oct.
4085 Added a bit of code to the demo client to decode & display
4086 ASN.1-structured records represented in the octet-aligned branch of
4087 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
4089 Added z_ext_getentbyref() to the ASN module. Doc updated.
4091 * Completed the SCAN definition in the ASN module. This may break SCAN
4092 code based on older YAZ-versions at compile-time. The fix is easy -
4095 * Added 'displayTerm' and OtherInformation to the TermInfo structure
4096 under the SCAN definition. Remember to initialize this, server-people.
4098 Comstack should now support the WAIS protocol in TCP/IP mode. Note
4099 that this does not extend to ODR and ASN.
4101 Comstack allows insertion of established socket (primarily for
4102 inetd-operation of servers). Doc updated.
4104 Front-end server can now start from the inetd in TCP mode. Doc
4107 --- 1.0pl4 1996/1/24
4111 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
4112 the rank and record number.
4114 Adjustments to the frontend server.
4116 Fixed diagnostic BER dumper. It ignored the file argument.
4120 Various changes to retrieval module.
4122 Changed the union discriminators of the protocol files from enums to
4123 ints paired with #defines.
4125 *Changed oident.class to oident.oclass to avoid a reserved word in C++
4128 *Changed operator in the RPN structure to 'roperator', again to avoid a
4131 Fixed problems in Explain decoders/encoders.
4133 --- 1.0pl2 1995/12/6
4135 Memory bug in log module fixed.
4137 --- 1.0pl1 1995/12/5
4139 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4141 Bug in Explain DatabaseInfo module fixed.
4143 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4147 The shift to v1.0 signals that we now consider the *core* functionality
4148 of YAZ reasonably stable (the core being more or less equivalent to
4149 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4150 tested (Explain not at all - though that will happen soonish).
4152 Minor changes to code to support Windows port.
4154 Various minor changes after we're getting to use GRS-1 & co. more.
4156 Added Espec-1 format.
4158 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4159 of the protocol and it cannot be selected when encoding (maps into 'string'
4160 when decoding). Needed to talk to some servers.
4162 Demo client can request simple element set names.
4164 Added Diagnostic Format encoders/decoders.
4166 Added simple Close handling to frontend server (no hooks for resource
4167 reporting yet), and demonstration client.
4169 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4171 --- 1.0b3 1995/08/24
4173 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4174 handled incorrectly when records were requested in the searchResponse. This
4175 will only affect you if you use the frontend-server.
4177 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4178 Test-client will ask for and print GRS1. Ztest will return dummy records
4181 Added Explain encoders/decoders to the service-level API. Untested.
4183 Added Extended Services: Item Order encoders and decoders to the Service-
4184 level API. Untested. We could use a recent copy of the pertinent bits
4185 of the ILL protocol to add those bits.
4187 Added diagnostic format 1 encoders/decoders to the service-level API.
4190 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4191 odr_cons.c, which causes a more correct output.
4193 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4194 was always set to 0 when no records were requested in the searchRequest.
4196 * Added better external-handling. This shouldn't harm old code that
4197 *encodes* externals. It can break code that looks for a
4198 'single-ASN1-type' representation, since those types that are known
4199 are now decoded immediately. Look at the SUTRS sample code in
4200 seshigh.c and client.c. Documentation updated.
4202 Handling of structured records in bend_fetchresponse. Length -1 marks
4203 structured record, type is deduced from format field.
4205 --- 1.0b2 1995/06/27
4206 Fairly quick maintenance release to add SUTRS support.
4208 Fixed handling of SUTRS records in the demonstration client.
4210 * Added format field to the bend_fetchrequest and bend_fetchresponce
4211 structures of the backend API (frontend server). When the record is
4212 returned, the value of the format field is mapped to an OID. The
4213 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4214 of the record. The special value VAL_NONE in the bend_request means
4215 that no specific format was requested by the client. Documentation
4216 updated accordingly. Test server (ztest) will return a fixed dummy
4217 SUTRS record if your client requests SUTRS.
4219 Documentation updated accordingly.
4221 You can now set external libraries and RANLIB support in the top-level
4225 First public release.
