5 Refactor ssl_put and tcpip_put to one function YAZ-832
7 Refactor ssl_get and tcpip_get to one function YAZ-831
9 Fix SEGV yaz-client for HTTP decoding error YAZ-829
11 Fix buffer overflow in cmd_elements in yaz-client YAZ-828
15 Fix test_sru.sh fails in pazpar2 YAZ-826
16 Unfortunately a regression occurred with YAZ 5.10.0 that would make
17 Pazpar2 fail for HTTP connections.
21 Use CONNECT for SSL backends and for Z39.50 thru HTTP proxy YAZ-825
22 Introduce cs_create_host2 which returns if connection should be
23 proxy aware (HTTP:absoluteUri or Z39.50 proxy:vhost in init).. For CONNECT,
24 the connection is NOT proxy aware (no absoluteUri and no Z39.50 vhost).
26 Fix http proxy fails with yaz-client YAZ-824
30 Fix 0 ptr reference for OPAC records from XML YAZ-822
34 Extend yaz daemon facility to assist int log rotation YAZ-818 YAZ-819
38 record conv: 'select' return org record if no x-path match YAZ-814
40 retrieval: pick matched element-set rule YAZ-813
42 Fix crash in record conv rule 'select' YAZ-812
46 record_conv: selection by X-Path YAZ-811
47 That's a new step in record conversion system (<select path=".."/>)
49 Document record render parameters for ZOOM - including base64
53 Fix application/x-www-form-urlencoded + empty YAZ-810
54 A SEGV occurred if Content-Type was "application/x-www-form-urlencoded"
55 and empty content was supplied.
57 Fix yaz-iconv man page for typos and incorrect example. YAZ-809
59 Fail hard if Bison is not found and is needed YAZ-808
63 Enable YAZ backtrace for programs YAZ-802
65 Update NMAKE makefile to use Visual Studio 2013 along with ICU 54.1,
66 Libxml2 2.9.2, Libxslt 1.1.28.
68 Fix daemon: parent process stops before child YAZ-806
69 Try to fix the situation where parent process stops before
70 child has acknowledged it .. SIGUSR2 back!
72 daemon: log message when keepalive stops.
76 Fix yaz-marcdump segfault YAZ-801. Problem in YAZ 5.6.0/5.7.0 and
77 would make yaz-marcdump crash when from-character set was issued.
81 Dump backtrace in case of SIGABRT, SIGSEGV YAZ-787
82 New function yaz_enable_panic_backtrace which enables backtrace
83 handler for current process. The handler will call backtrace always,
84 then gdb to provide as much detail as possible.
88 When marc-8 charset is specified when decoding MARC records, yaz-marcdump
89 and ZOOM record render will inspect leader 9 and switch to UTF-8
90 (Unicode) if that holds 'a'. This changes behavior, but is considered
91 safe because only MARC21 with leader 9='a' are Unicode. YAZ-800
93 Fix cs_put may reconnect if send fails. YAZ-798
97 Fix cannot build YAZ on jessie : libgnutls-dev is gone YAZ-797
101 Extended comstack with outgoing IP YAZ-795.
102 For cs_create_host + cs_create_host_proxy the vhost may be followed
103 by a outgoing host/IP. Separator is blank.
107 Add YAZ_EXPORT to cql_transform_r fixes YAZ-793 . This issue fixes
108 linker error with yazpp on Windows.
112 Fix uri array may overflow in yaz_solr_encode_request YAZ-775
114 Fix PQF to Solr conversion may produce invalid Solr query YAZ-792
116 0 ptr reference in handling Solr response with error YAZ-791

129 improve diagnostics YAZ-783 YAZ-784
133 Stop building debs for Ubuntu raring, quantal, oneiric.
135 CCL YAZ-781: for multiple use attributes in a specification the
136 generated RPN will perform @or on each term.
137 For spec: term u=31 u=1016
138 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
140 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
142 CCL YAZ-779: combo qualifier should allow for forward references
144 Fix buildconf.sh, automake too old on centos5 YAZ-778
145 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
146 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
147 accepts it without a warning.
151 GFS: client_query_charset conversion YAZ-777
152 This is a feature for Z39.50 clients that sends queries that are not
153 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
154 encoding given to UTF-8.
156 Echoed SRU arguments support YAZ-776
157 This is achieved with new function yaz_srw_get_pdu_e.
159 ZOOM: expire times set for redis/memcached YAZ-772
160 For both redis and memcached option --expire=seconds sets expire
161 time for a result-set/search. Default time is 600 seconds (10 minutes).
165 No [rest of output is omitted] limit for yaz_log YAZ-774
167 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
169 For ICU testing, pass -o to yaz-icu. This will test the
170 icu_iter_get_org_info function.
172 Fix null ptr reference for freeReplyObject YAZ-773
176 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
178 RPM: do not build with libmemcached support. The libmemcached library
179 on CentOS 5/6 does not work reliably for us (redis to the rescue).
181 configure: only allow libmemcached version 0.40 or later. That's the version
182 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
183 that's not an option, consider redis.
187 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
189 Fix zoom+memcached: present request out of range YAZ-767
193 CCL: add new qualifier r=omiteq which will omit relation=equals
194 for ordered relations. This should be used in combination with either
197 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
199 Solr: simplify yaz_solr_decode_response
201 Solr: use different local var for string manipulation
203 Solr: Get rid of hardcoded limit of extra_args
205 Solr: encode lucene query type YAZ-736
206 Make sure the queries are treated as traditional "lucene", because that's
209 Fix ZOOM HTTP redirect failing on Windows+Solaris YAZ-755
213 Build packages for Ubuntu Trusty Tahr 14.04 LTS
215 wrbuf_cstr: fix off by one error.
217 wrbuf_buf: make it always return non-NULL
218 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
222 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
224 zoomsh: offer option -a apdulog
225 As we're used to from yaz-client and GFS based servers.
227 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
228 existing setting apdulog takes effect.
230 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
235 Add re-entrant CQL/Solr/RPN query conversion functions.
236 The re-entrant functions are: cql_transform_r,
237 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
238 These have same functionality as cql_transform,
239 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
240 return the additional infomration as WRBUF to make them re-entrant.
242 Remove CQL to Solr conversion and base solr_transform_t on
243 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
244 data structure as cql_transform_t.
246 cql2pqf utility allows RPN to Solr conversion
248 Fix assert in ZOOM when http connect fails YAZ-757
250 --- 5.0.22 2014/04/09
252 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
254 wrbuf_cstr: make it thread safe YAZ-753
256 yaz_log_init_file may take fd=<no> to open log file at the FD given.
258 --- 5.0.21 2014/03/21
260 Offer new utility function zget_AttributeList_use_string.
262 New conversion step, solrmarc, for record conversion module.
264 --- 5.0.20 2014/03/13
266 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
267 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
270 --- 5.0.19 2014/03/10
272 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
273 The standalone ZOOM sort was completely broken since 5.0.13.
275 ZOOM: generate event Connect rather than None for partial connect
276 (in fact getaddrinfo resolving).
278 ZOOM: only supply clientIP for InitRequest. Rather than for all
281 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
283 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
284 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
285 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
287 New "Facets" section in the documentation.
289 --- 5.0.18 2014/02/27
291 Call exsltRegisterAll in yaz_init_globals, so that all applications
292 using YAZ will have EXSLT things enabled.
294 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
296 Update various URLs to the re-organized SRU pages at LoC.
298 --- 5.0.17 2014/02/26
300 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
301 introduced in 5.0.12.
303 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
304 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
305 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
308 --- 5.0.16 2014/02/25
310 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
312 --- 5.0.15 2014/02/24
314 Fix gcrypt not properly initialized YAZ-740.
316 --- 5.0.14 2014/02/19
318 Describe memcached option for ZOOM.
320 ZOOM: throw present request out of range again YAZ-739
321 Was removed in YAZ 5.0.13.
323 --- 5.0.13 2014/02/18
325 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
326 with localtime_r when threads + fork is used (such as Metaproxy).
328 yaz-config: quote some RHS values (that might include blanks)
330 zoomsh: shows SearchResult-1
332 zoomsh: sortby command
334 zoomsh: use proper list of connections and result sets YAZ-725
336 Avoid yaz_log in sigterm handler for GFS YAZ-737
337 Logging is still performed, but outside sig handler.
339 New ZOOM C feature: result-set caching with memcached. Example:
340 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
342 Remove SSL via OpenSSL support YAZ-732
343 Also deprecate two functions from comstack that aren't working with
344 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
346 Revert "Bison: use %name-prefix directive rather than -p option"
348 --- 5.0.12 2014/01/22
350 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
352 SRU GET/Solr base URLs may hold additional ?args YAZ-729
353 ZOOM option extraArgs already does this, though. It seems useful
354 when dealing with Solr targets to limit by filter, eg.
355 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
357 Remove #fragment for HTTP request encoding YAZ-730
359 Doc: Update list of DLLs/LIBs
361 Doc: update href link to Unix utils and Git.
363 --- 5.0.11 2014/01/15
365 ZOOM: fix "lost connection" problem with servers that uses both squid
366 and another proxy behind it that returns Location headers with relative
369 zoomsh: do not use readline for stdin (no tty) YAZ-724
370 Just use fgets in that case. If the user hits Ctrl-D a new-line
373 zoomsh: empty command ignored YAZ-723
374 rather than performing exit of zoomsh.
376 yaz-url utility offers option -v to enable verbose mode.
378 yaz_url uses yaz_check_location and offers verbose mode.
380 Add new function yaz_check_location.
381 This function gets an absolute URI from Location (HTTP redirect).
383 cookie API: introduce yaz_cookies_reset
385 Update cql.y for newer bison YAZ-720
386 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
387 longer supported. Instead one must use %lex-param and %parse-param .
389 --- 5.0.10 2014/01/09
391 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
394 rpn2solr: support truncation left(2), left&right(3) YAZ-718
396 Mention SRU version 2.0 in yaz-client man page.
400 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
405 Make cs_parse_host public.A
407 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
408 introduced in YAZ 5.0.6.
412 Fix buffer corruption for yaz-ztest record fetch.
416 Allow yaz-ztest to return user-defined records (one record per file).
417 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
419 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
420 Use the stream write instead of odr_printf which has a 4K tmp buffer.
422 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
426 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
427 can read and write this format. For record format JSON, yaz-ztest returns
428 MARC-in-JSON records.
430 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
431 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
435 Improve error reporting for ICU chains YAZ-707
436 Report config element+rule when ICU status is "failure".
438 ZOOM: stop fetching if present response has no records YAZ-710
439 Some targets return less records than their hit count would suggest.
440 This prevents ZOOM from continuing to fetch records if any present
441 response has 0 records in the response.
443 Ensure that GFS calls exit if any listener fails YAZ-710
444 Before, if XML config was in use, it would start the default
449 yaz-ztest: -V shows version (like yaz-client -V)
451 New iconv encoding: danmarc YAZ-692
453 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
455 daemon: only wait for immediate child rather than all children. YAZ-704
457 yaz-client: fix setting of SRU record schema. If scheme was unset, it
458 could lead to invalid memory reference.
462 yaz-ztest returns schema for MARCXML test records. SRU require that
463 recordSchema for records.
465 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
466 instead of non-surrogate diagnostic. This is a per-record failure.
468 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
469 may refer to multiple listeners now. Attribute listenref is a comma separated
472 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
473 option is given for GFS, the dirname of filename (for -f) is used
474 as prefix for options such as cql2rpn, ccl2rpn, etc.
476 Content-Type charset fixes YAZ-701 . Do not inspect charset in
477 Content-Type header for SOAP when decoding SRU. The payload (XML)
478 itself tells what encoding it is. In response, never supply encoding
479 in Content-Type. The response payload (XML) tells what it is (with no
480 encoding in XML it's UTF-8).
482 HTTP decoding: allow blanks in URL paths YAZ-700
486 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
487 and facets. Ensure recordData and recordSchema are always present in
488 record element, because they are required.
490 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
493 Simplify in a lot of places using odr_strdupn.
495 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
499 Increase various buffers in GFS's statserv_options_block
500 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
501 This change makes many type-casts redundant, and, thus simplifies code.
503 Remove last bits of WAIS support.
505 Remove member 'size' from Odr_oct.
507 Slim down the public part of 'struct odr'. Most elements are not part
508 of struct Odr_private.
510 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
511 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
512 In particular facets are supported in both client - and server side.
513 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
514 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
515 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
516 both request/response). This is what a search handler in the GFS
517 will see (regardless of whether operating in SRU mode or Z39.50).
519 Changes to the srw.h (SRU/Solr) definitions include:
520 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
521 (char*), which replace union query and query_type (int). This is because
522 SRU 2.0 supports a queryType parameter. This also means that, to carry
523 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
524 x-pquery=PQFstring (extention parameter). The extension parameter
526 - New element, packing, that has information about SRU
527 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
529 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
531 New element, packing, in Z_SRW_explainRequest.
533 New elements in Z_SRW_scanRequest, queryType and scanClause.
534 These replace query_type and scanClase untion. This is similar to what
537 --- 4.2.69 2013/10/01
539 GFS: log when closing down - at least SIGTERM YAZ-684
540 Also change formatting WRT PID logging a bit.
542 Improve display of MARC records with multi-byte subfield IDs YAZ-695
543 In some rare cases subfield identifiers are multi-byte characters.
544 This will try to deterime length of those and split accordingly.
545 This affects display in line mode as MARCXML/MarcXchange. The encoding
546 of ISO2709 is the same.
548 Change inp argument to const for yaz_read_UTF8_char.
550 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
552 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
554 Better check of marc leader info YAZ-691
555 Problem is that some systems generate MARCXML/MarcXchange with
556 funny headers. These will not work if encoded as ISO2709.
557 Some tests produce new output, due to updated warning messages
559 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
561 yaz-client: display MAB records YAZ-689.
562 Thanks for Heiko Jansen for this patch.
564 New utility z_get_HTTP_Response_server which allows both HTTP server name
565 and HTTP server URL to be given in response.
567 Debian: do not depend on obs tcl8.3.
569 Debian: do not depend on obs libicu36-dev.
571 --- 4.2.68 2013/09/23
573 GFS: pass additionalSearchInfo to search memeber search_input if
574 given. Otherwise pass otherInfo. Request for facets and other search
575 related things will be passed there in future versions of YAZ.
577 New ZOOM setting, authenticationMode, which allows authentication
578 paramters to be encoded in the URL rather than via HTTP Basic auth.
581 rpn2solr: fix nested AND/OR handling. YAZ-685
583 Add comparison routines for some Z-types, such as NamePlusRecord,
584 RPNQuery, Query, RecordComposition and OtherInformation.
586 --- 4.2.67 2013/09/19
588 Don't decode MAB as MARC. Just like we don't attempt to decode
589 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
591 CCL: allow quoted terms for date ranges. YAZ-681
593 Introduce ccl_parser_qual_search. This function makes old function
594 ccl_qual_search, from YAZ 2, available again.
596 Add yaz_facet_list_to_wrbuf. YAZ-683
598 --- 4.2.66 2013/09/11
600 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
601 schema was given for search. YAZ-675
603 Add Solr date range searches. YAZ-621
605 --- 4.2.65 2013/08/22
607 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
609 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
611 ISO2709/MARC parse most octet aligned records; not just those that
612 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
613 MARC parse more records instead of just dumping as is. YAZ-670
615 ZOOM: proper caching for variations of record schema. YAZ-671
617 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
619 --- 4.2.63 2013/07/17
623 --- 4.2.62 2013/07/11
625 New utility z_get_HTTP_Response_details - an extended version of
628 New utility yaz_url_get_error which returns error message of last
629 failed yaz_url_exec call.
631 yaz-url and url functions: allow max HTTP redirects to be controlled.
633 New functions yaz_file_glob2, yaz_xml_include_glob.
634 These functions takes a flags parameter, which, for now only controls
635 whether to fail inclusion of a non-existing file (without glob
636 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
638 --- 4.2.61 2013/06/20
640 For MARC XML parsing, allow record without leader. A fake/default leader
641 is inserted and a warning is tagged with the record.
643 ICU: fix leak in in icu_iter_get_org_info.
645 --- 4.2.60 2013/06/14
647 ICU: fix bug in icu_iter_get_org_info (un-init variable).
649 --- 4.2.59 2013/06/11
651 Implement z_HTTP_header_remove.
653 --- 4.2.58 2013/06/11
655 ICU: Disallow 0 ptrs for some ICU string utilities.
657 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
658 returns original tokens (before normalization).
660 CCL: avoid z39.58/regex truncation when not needed. Apply only the
661 conversion of those masks, when absolutely necessary.
663 CCL: configurable masking character - @mask. Default masking character
666 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
667 full response anyway, so a Transfer-Encoding header will obstruct the
670 --- 4.2.57 2013/05/15
672 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
673 picking a socket. Problem is that some systems has IPV6 support, but
674 we can't create sockets for them, so we pick AF_UNSPEC first.
676 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
677 use content_len to determine resulting Content-Length in HTTP response
678 and NOT Content-Length supplied in headers by user.
680 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
681 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
683 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
686 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
687 with big endian and unsigned char (by default).
689 --- 4.2.56 2013/04/26
691 Fix yaz-client connect (crash in 4.2.55).
693 --- 4.2.55 2013/04/26
695 Fix proxy/host problem for ZOOM that could occur if unix sockets
698 New Debian package libyaz4-dbg.
700 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
701 differently in tcpip_close.
703 --- 4.2.54 2013/04/17
705 Windows installer of YAZ includes YAZ4J as a component.
707 CQL: allow "extra terms" again, by default. Thus, the CQL parser
708 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
709 and earlier. CQL parser may operate in strict mode where queries
710 not conforming to the standard BNF are rejected (syntax error).
711 Whether the CQL parser operates in strict mode is controlled with
712 cql_parser_strict . Strict mode enabled with option -S for utilities
713 cql2pqf and cql2xcql .
715 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
717 --- 4.2.53 2013/04/10
719 New charset, MARC-8c, which is like MARC-8 but allows control characters
720 0x01 through 0x1F, except ESC to be passed through verbatim.
722 Fix a problem with duplicate sub field character in MARC output. Problem
723 happened only when output was MARC-8 encoded.
725 --- 4.2.52 2013/04/03
727 yaz-ztest: Use hash for fake hit count. Before, random number was used.
728 This is problematic for unit tests using yaz-ztest. This patch also makes
729 a hash for CQL queries. For RPN, any term with a leading digit will be
730 treated as pseudu hit count (to force any particular hit count by a client).
732 yaz-ztest: return unique MARC dummy records. Beyond record offset
733 24, the author surname is patched with offset to make all records
736 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
737 on system wide default (/proc/sys/net/ipv6/bindv6only).
738 @4 binds to IPV4 only. @6 binds to IPV6 only.
740 Update CQL API documentation a bit
742 CQL: don't accept extra terms for queries. Makes the CQL parser
743 stricly conformant to the standard.
745 --- 4.2.51 2013/02/12
747 GFS: scan handler gets extra_args from request and may return extra
748 response data . That's for SRU only.
750 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
752 --- 4.2.50 2013/01/30
754 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
756 OPACXML: sync spelling of availabilityDate in XML to that of Schema
757 opaxxml.xsd. The schema had the correct spelling of this member always.
758 The ASN.1 was mis-spelled and still is (API change) - we are
759 not changing this. However, the OPAC to XML conversion had yet
762 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
765 New function, z_ext_record_oid_nmem, which is similar to
766 z_ext_record_oid but takes NMEM rather than ODR
768 --- 4.2.49 2013/01/18
770 ICU: New conversion element 'join' which joins tokens into one
771 with a custom character given by rule attribute.
773 --- 4.2.48 2013/01/10
775 New GFS search member: present_number. This is a hint to the
776 search handler how many records are going to be fetched immediately
777 following search. There's no guarantee that it's going to be the case,
778 since it depends on hit count (for Z39.50 piggyback) and whether errors
781 Make a few functions static (private). The functions getbyte_stream,
782 ungetbyte_stream and yaz_gets are now private. They were never declared
785 yaz-marcdump: exit(5) for serious decoding errors
787 ISO2709 decoding: be more picky WRT header
789 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
790 was only used as to indicate that next-result-set-position should be
792 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
793 Based on patch from Ashley Sanders.
795 Make some functions static/private in PQF parsing. Those functions were
796 never declared in a public header and so should not be in use by
797 applications based on YAZ.
799 --- 4.2.47 2012/11/23
801 ZOOM: special options to control APDU logging.
802 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
803 logging of APDUs until "saveAPDU" option is set again. If logging is
804 already enabled the effect is that current APDU buffer is cleared.
805 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
806 logging (default behavior on new connection).
807 The APDUs sent/received can be obtained by using
808 Using ZOOM_connection_option_get(c, "APDU") or
809 ZOOM_connection_option_getl(c, "APDU", &l).
811 GFS: relay implementation_version from backend
812 From 3.0.40 and later, implementation_version from backend was
813 not used in init response at all.
815 --- 4.2.46 2012/11/15
817 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
818 mode at all. Probably never did.
820 Make a new version of ztest.pem that, at least, is not expired.
822 --- 4.2.45 2012/11/13
824 Fix description of CCL directive 'case'.
826 More tight checking of form arguments (yaz_uri_to_array). Makes
827 YAZ better at rejecting big and/or bad POSTs.
829 SRU decoding does not report more than up to 10 invalid arguments.
831 rpn2cql: less quotes in generated terms. Semantics unchanged, but
832 it's prettier this way.
834 --- 4.2.44 2012/10/25
836 New utility yaz_decode_init_diag. Defined in proto.h.
838 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
839 given for unix local socket.
840 The COMSTACK string for doing so is:
843 unix:/myfile:tcp:localhost:9999/mybase
844 unix:/myfile:localhost:9999/mybase
845 unix:/myfile:http://fakehost/mybase
847 debian: Use dpkg-buildflags in build process.
849 --- 4.2.43 2012/10/19
851 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
852 global's SRU service uses a recordPosition scheme starting from zero.
853 First record's position should be one
854 according to the standard.
856 --- 4.2.42 2012/10/18
858 Allow more namespaces for SRU. This is to allow, for example, an
859 incorrect namespace returned from server
860 http://services.igi-global.com/sru .
862 Minor fixes for compilation on Windows.
864 --- 4.2.41 2012/10/11
866 daemon: log total number of bad signals from child on stop so that it
867 is more easy to spot problems with child worker processes.
869 retrieval: empty backend name attribute omits element set
870 from being used in retrieval.
872 --- 4.2.40 2012/10/04
874 Implement Solr sort strategy "solr", similar to sru11 sorting.
875 This will implement the correct parameters on Solr requst to do
878 --- 4.2.39 2012/09/28
880 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
883 MARC: Extra/missing indicator handled for MARCXML.
884 The indicator length is given in header and is the same for the
885 whole record. If attributes ind1, ind2 are missing, then content
886 character defaults to blank. Extra indicator attributes (beyond)
887 indicator length are treated as an error.
889 Reformat: delete trailing whitespace
891 --- 4.2.38 2012/09/17
893 MARC: fix non-ASCII characters for leader. This is to ensure we can
894 generate XML in UTF-8.
896 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
897 in one node with structure word.
899 --- 4.2.37 2012/09/04
901 yaz-json-parse: JSON output may be pretty printed by using option
904 Increase default value of max message for Z39.50 Init for GFS, ZOOM
905 and yaz-client. Old value was 1 MB. New value is 64 MB.
907 --- 4.2.36 2012/08/22
909 yaz-client: don't display bogus records from SRU servers. Some SRU servers
910 return more records than given by *maximumRecords*. Skipping those in
913 record_render: simplify buffer return handling and fix at least one bad
914 memory reference, that broke the test_embed_record sometimes.
916 Allow http://user:pass@host notation for yaz_url_exec.
918 zoomsh: allow shell command to be executed. Via the system(3) call.
920 yaz_poll: Allow num_fds == 0
922 yaz-client: fix bad encoding of "itemorder item". The itemorder
923 item <no> - command forgot to use length of encoded Item Request
924 package. Error present since YAZ 3.
926 yaz-ztest: fix bad usage of session handle. Bug was introduced when
927 result sets were saved (271a9c83).
929 SRU recordPacking: guess record packing in response rather than looking
930 at the recordPacking element which, OF COURSE, changed semantics in SRU
933 Decode SRU 2.0 responses. The official namespace for responses, according
934 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
935 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
936 nature.com's server, however, usee namespace
937 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
938 we are now using a glob-expr to match up the namespace. ZOOM C and
939 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
940 I can not find a single real example showing the "real" namespace in
941 the documentation from OASIS. The namespace for requests is different
942 from responses, but this is not added to YAZ yet, when we don't encode
945 --- 4.2.35 2012/06/26
947 zoom/record_render: add support for Base64 decoding fo MARC records
948 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
949 which will decode base64 + ISO2709 marc-8 encoded material from text node
952 --- 4.2.34 2012/06/07
954 Add missing definitions ZOOM_resultset_get_facet_field_by_index
955 and ZOOM_resultset_facets_names.
957 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
960 Change APDU dump printing to avoid long leading blanks. For levels 16
961 or larger the level is shown and the indentation is truncated but
962 recursed with modula 8. This makes it still reasonable easy to read
963 - even for nested BER dumps.
965 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
966 return 0 (incomplete package) in case where the BER package was
967 considered too nested (return value of -2).
969 dumpber: lines of level 15 are not indented further. Two spaces per
970 indentation; indentation 15 or more is indented to a fixed indentation
971 and augmented with a level=<no> indication.
973 zoomsh: increase max size of command+args
975 GFS: No limit in RPN buf size in CQL to RPN conversion.
977 --- 4.2.33 2012/05/09
979 New function for daemon utility, yaz_daemon_stop .
981 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
983 --- 4.2.32 2012/04/25
985 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
986 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
988 --- 4.2.31 2012/04/23
990 YAZ daemon utility relays SIGUSR1 to child process.
992 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
993 would result in en empty database list - which in turn would result in
994 encoding failure for search.
996 Fix reading beyond string in yaz_sort_spec.
998 --- 4.2.30 2012/04/11
1000 Add two new SRU diagnostics:
1001 236: Access to specified database denied
1002 1015: Init/AC: Maximum number of simultaneous sessions for Userid
1004 Document the very useful ZOOM-C option "apdulog".
1006 CQL to RPN: term may be passed through verbatim. This is enabled with
1007 truncation.cql . The assumption being that the term is already CQL.
1009 --- 4.2.29 2012/03/20
1011 record_conv: leader spec may be given for marc element.
1012 The leader spec is given as attribute leaderspec for element marc.
1013 For example to convert a MARC21 record from MARC-8 to UTF-8:
1014 <marc inputformat="marc" outputformat="marc"
1015 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
1017 record_conv: allow user-XSLT params. For example:
1018 <xslt stylesheet="MARC21slim2DC.xsl">
1019 <param name="myparameter" value="myvalue"/>
1020 <param name="otherparameter" value="othervalue"/>
1023 record_conv: fix error handling for missing marc charsets.
1025 CQL: fix extra terms in wrong order.
1027 --- 4.2.28 2012/03/06
1029 record_conv: modify new API for conversion types. The conversion types
1030 may be passed in new functions yaz_record_conv_configure_t and
1031 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
1033 Avoid mixed statement/variable declare; fixes compilation with Visual
1036 --- 4.2.27 2012/02/28
1038 Add non-standard SRU diagnostic: 235: "Database does not exist".
1039 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
1040 Update SRU to Bib-1 diagnostic maps accordingly.
1042 CCL: add two new diagnostics for unsupported masking. The new
1043 diagnostics are: "Embedded truncation not supported" and
1044 "Single charcacter mask not supported".
1046 --- 4.2.26 2012/02/23
1048 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
1050 --- 4.2.25 2012/01/11
1052 Build YAZ for Ubuntu Oneiric.
1054 CCL: allow parantheses for proximity operands. For example CCL query
1055 (a) % (b) is now allowed.
1057 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
1058 marked dead, rather then being destroyed. If not, the session memory is
1059 being free'd before the search/scan handler is finished. Also destroy
1060 'request' memory in request_release rather than in various places,
1061 which resulted in leaks from time to time.
1063 --- 4.2.24 2011/12/21
1065 cql_sortby_to_sortkeys: honor sort prefix.
1067 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
1068 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
1069 The rpn2cql family of functions now always returns quoted CQL terms.
1071 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
1073 --- 4.2.23 2011/12/15
1075 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
1076 sequence is treated as one. For example, &&a=b&&&c& is identical to
1079 --- 4.2.22 2011/12/05
1081 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
1082 APDUs for a connection to a WRBUF.
1084 --- 4.2.21 2011/11/23
1086 Fix cql_sortby_to_sortkeys. Completely broken before.
1088 Make CCL's @truncation work again.
1090 --- 4.2.20 2011/11/09
1092 New ZOOM connection setting: tproxy. It's like proxy, but does not
1093 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
1094 to set resolved address + port for a connection outside ZOOM itself.
1096 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
1098 --- 4.2.19 2011/11/07
1100 Fix uninitialized variable in Solr spell support (could cause SEGV
1101 for SRU response decoding).
1103 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
1104 back-end's addinfo through into the ZOOM response addinfo.
1106 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
1107 they are separated by a colon and a space rather than simply
1110 --- 4.2.18 2011/10/28
1112 Add support for Solr spell-checking/suggestions through ZOOM.
1113 If a Solr target has been configured correctly for spelling-checking
1114 and suggestions, these will now be returned on the ResultSet option
1115 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1117 --- 4.2.17 2011/09/28
1119 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1120 with a flag whether to substitute escape sequences or not.
1122 --- 4.2.16 2011/09/22
1124 Fix nmem_strsplit_escape to substitute escape char properly.
1126 New option for zoomsh -e , which makes it abort on first error and
1127 return process exit code to indicate success/failure.
1129 YAZ options utility supports special option -- which makes all it treat
1130 all following arguments as non-options.
1132 --- 4.2.15 2011/09/16
1134 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1135 searched if absolute filename is given.
1137 Fix conv_xslt() error-reporting when stylesheet is not found.
1138 (The value of fullpath is meaningless in this situation.)
1140 --- 4.2.14 2011/09/07
1142 Fix problem in CQL sort node creation: un-initialized memory.
1144 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1145 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1146 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1149 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1150 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1152 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1153 will make it possible to use both single-character mask (#) and wildcard (?)
1154 in CCL . Throw diagnostic for left truncation because that is not supported
1157 --- 4.2.13 2011/09/01
1159 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1160 cases using escapes (\-sequences) and masking.
1162 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1163 would result in a read one byte beyond string.
1165 rpn2ccl may use Z39.50 masking for terms (t=z).
1167 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1169 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1170 not --cppflags (which seeems like an error in icu-config).
1172 --- 4.2.12 2011/08/27 RPM package only
1174 cql2ccl: fix conversion of terms: operator characters were not
1177 --- 4.2.11 2011/08/25 RPM package only
1179 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1180 CCL parser will map both # and ? to their regular expression
1181 quivalents (. and .*).
1183 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1184 of reserved CQL characters.
1186 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1187 is, so that they are passed through.
1189 --- 4.2.10 2011/08/24
1191 ZOOM SRU mode: more aggressive re-connect.
1193 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1194 made available as a utility function, declared in <yaz/logrpn.h>
1196 rpn2cql_structure() supports proximity nodes (except that the Type-1
1197 proximity node's "exclusion" binary is ignored, as there is no way to
1198 express that in CQL). Fixes bug #4564.
1200 --- 4.2.9 2011/08/18
1202 Fix SEGV that could occur if set command of zoomsh was given without
1203 value (2nd argument).
1205 Fix SEGV that could occur if unsupported transport was given for
1206 COMSTACK - say https (when SSL was unavailable).
1208 Build yaz-url on Windows too.
1210 --- 4.2.8 2011/08/11
1212 New utility to get web content. Header is url.h. A command line tool
1213 yaz-url is part of the distribution and packages.
1215 Fixes for SSL COMSTACK (when gnutls is in use).
1217 New functions yaz_base64{encode,decode}. Header is base64.h.
1219 --- 4.2.7 2011/08/03
1221 ZOOM C includes HTTP response buffer as additional info if it fails
1222 to decode the SRU response.
1224 Make wrbuf_json_puts available.
1226 --- 4.2.6 2011/07/28
1228 zoom: throw diagnostic for invalid value for option "sru". Before a
1229 bad SRU request was sent.
1231 Adding new utility wrbuf_vp_puts.
1233 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1235 --- 4.2.5 2011/07/21
1237 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1238 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1239 redirect was used at the same time.
1241 MARC line mode decoding: be less picky about length given - first
1242 5 digits of header that is.
1244 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1246 Changes to decoding of SRU records: a record with recordPacking=xml is
1247 modified with a new root element <yaz_record> if the recordData contains
1248 multiple children elements. This is to make the record XML parseable
1251 RPN to Solr conversion: encode special characters.
1253 Generic Frontend Server: fix uinitialized member, stepSize.
1255 --- 4.2.4 2011/06/21
1257 Fix a bug in SRU decoding of records.. The database records stored
1258 had un-initialized memory, but it would only be seen with yaz_record_render
1259 and type_spec="ext" .
1261 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1263 --- 4.2.3 2011/06/17
1265 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1267 --- 4.2.2 2011/06/10
1269 Add new utilities to convert from CQL to CCL . These utilities have
1270 prefix cql_to_ccl defined in cql.h.
1272 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1273 lead to memory heap corruptions when ICU utilities were in use.
1275 --- 4.2.1 2011/06/07
1277 Make compilation work without Libxml2.
1279 yaz-client: remove redundant blanks in display of searchResult-1 term
1282 --- 4.2.0 2011/05/18
1284 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1285 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1287 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1288 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1289 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1290 Note that the CQL sortby spec is only converted when the GFS is already
1291 converting from CQL to RPN (cql2rpn element).
1293 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1294 specify whether to collapse delimitors or not. The existing nmem_strsplit
1295 do collapse (collapse parameter = 1).
1297 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1299 Rename internal func yaz_use_attribute_create. While non-static, this
1300 function is not declared in a public header.
1302 --- 4.1.7 2011/03/15
1304 Add -lCrun when linking with ICU on Solaris.
1306 More quicks character set conversions for OPAC records.
1308 --- 4.1.6 2011/03/10
1310 fix problem with record_render: records were converted (character set
1311 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1313 --- 4.1.5 2011/03/08
1315 SRU: add methods for handling DADS SRU-proxy facets.
1317 Separate OPAC record character set for ZOOM_record. yaz_record_render
1318 allows a character set given as charset=from/opacfrom,to where 'from' is
1319 the character set of a bibliographic record, 'opacfrom' is character set
1320 of OPAC record and 'to' is the target character set.
1322 --- 4.1.4 2011/02/21
1324 yaz-client: show may XML format records. Command show followed by 'format'
1325 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1328 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1331 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1333 --- 4.1.3 2011/01/27
1334 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1336 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1337 this package can be distinguished from other vendors.
1339 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1340 as determined by configure
1342 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1344 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1345 returns no error and no record, the present request is considered
1346 partial (only a subset of the records could be returned by backend), and
1347 so it is appropriate to set Present Status to partial-4.
1349 --- 4.1.2 2010/11/02
1351 Move yaz-config man pages to section 1.
1353 More documentation about Solr.
1355 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1356 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1357 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1358 peers on some Linux systems. However, in general that does not work
1359 so YAZ can not rely on that to work. Debian changed behavior in this
1360 respect from Debian lenny to Debian squeeze (still testing as of Oct
1362 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1364 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1366 --- 4.1.1 2010/10/05
1368 Fix yaz-config output: echo_source not set correctly by configure.
1370 --- 4.1.0 2010/10/05
1372 Solr Web Service support for yaz-client and ZOOM.
1374 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1376 --- 4.0.12 2010/08/17
1378 Z39.50 facet support. Facet specifications are passed for search in
1379 other-information with ASN.1 as defined in facet.asn and OID
1380 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1381 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1382 3 is limit (number of entries to get in response). yaz-ztest returns
1383 dummy facets if a client asks for them.
1385 --- 4.0.11 2010/07/09
1387 CCL fixes: bug 2895 and bug 3539.
1389 GR1-display: add comma in display - was removed by mistake in
1392 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1394 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1396 --- 4.0.10 2010/06/18
1398 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1399 result set from a connection. The result set will be on its own
1400 thereafter; no operations on it will perform retrievals from a target.
1401 Only cached copies are returned.
1403 ZOOM C:fix case for HTTP servers responding with Connection:close.
1404 Ensure that if there is a current task it is resumed (like fetching
1405 more records in a result set) . Bug #3484.
1407 PQF parser: use odr_atoi for Odr_int (not atoi)
1409 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1410 values that contain any non-digits are treated as string attributes
1411 (previously decoding only checked for leading character ([0-9]). PQF
1412 encoding: attribute string values are not surrounded by double-quotes.
1414 --- 4.0.9 2010/05/21
1416 New utility for managing threads - thread_create.h.
1418 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1419 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1420 but YAZ' implementation do.
1422 Fixes for yaz_cond-functions on Windows 7.
1424 DLL export more symbols.
1426 zoomsh: show record do NOT render opac.
1428 Remove *.la files from Debian and RPM packages.
1430 --- 4.0.8 2010/05/11
1432 Debian package libyaz-dev depends on libgnutls-dev again (was
1433 removed in YAZ 4.0.6, but due to Libtool it is still needed
1434 even though yaz-config do not list libgnutls libs).
1436 ZOOM: Use only one WRBUF for returning string results for
1437 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1439 ZOOM: ZOOM_connection do not use a shared pointer to
1440 ZOOM_resultset after ZOOM_resultset is destructed by
1441 user. Reverts to YAZ 4.0.4 behavior.
1443 --- 4.0.7 2010/05/04
1445 record-conv: fix problem with at least one XSL conversion -
1446 due to probably incorrect usage of XML XSL documents.
1448 --- 4.0.6 2010/04/29
1450 Fix yaz-config for static mode and the use of SSL (gnutls).
1452 --- 4.0.5 2010/04/29
1454 Forward decl timeval struct in mutex.h and gettimeofday.h.
1456 yaz-config: fix 'static' mode linking.
1458 --- 4.0.4 2010/04/28
1460 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1461 are wrappers for pthreads or Windows. For Windows these are put in
1462 a separate DLL: yaz_cond4.
1464 libyaz.la (whole source) is compiled with thread. If thread support
1465 is enabled enabled, all source of YAZ is compiled with treading support.
1466 This allows core utilities such as yaz_log to use thread facilities.
1467 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1468 thread utilities. This commit moves mutex utilities (mutex.c) from
1469 libyaz_server.la to libyaz.la.
1471 yaz-json-parse displays leading text until error.
1473 --- 4.0.3 2010/04/09
1475 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1476 patch from Giannis Kosmas.
1478 SRU: no longer URL encode SRU database. The URL for an SRU server is
1479 a URL and such is alreeady encoded - at least when given with leading
1480 http:// or https://. This reverts behavior to YAZ 3.0.50.
1482 Support for new MARC XML notation TurboMARC which like MARCXML is a
1483 complete representation of MARC/ISO2709.. This one, however, is more
1484 compact and allows for faster processing with XSLT. TurboMARC can be
1485 used in the marcdisp.h API, from the yaz-marcdump utility and from
1488 yaz-ztest can be configured - via the database - to perform certain
1489 delays when it performs operations search, present and single record
1490 fetch. This allows testers to make yaz-ztest act as a real or even slow
1491 Z39.50 server. Refer to the yaz-ztest man pages for details.
1493 --- 4.0.2 2010/03/09
1495 wrbuf_destroy allows NULL WRBUF passed to it.
1497 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1499 Add ZOOM_connection_close.
1501 No fixed size buffers for ZOOM shell - bug #3257.
1503 tstodr: make it work on s390 platform.
1505 New icu iterator-functions. The new icu_iter-functions makes it possible
1506 to use ICU chains from many threads.
1508 yaz-client: better syntax check for show command.
1510 --- 4.0.1 2010/01/26
1512 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1515 New simple local-file XML include facility which allows file glob-patterns.
1516 Refer to yaz/xml_include.h.
1518 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1521 ZOOM_record_get supports new parameter "format" which makes it format XML
1524 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1525 JSONText in ECMA-262) is JSONValue, not JSONObject.
1527 --- 4.0.0 2010/01/20
1529 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1530 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1532 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1533 POSIX/Unix builds .so with major version 4.
1535 Remove old LOG_-defines from log.h. They have been obsolete and
1536 undefined by default for the last 5 years.
1538 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1540 GFS: Remove socket (int *fd) from search_rr handler. The socket
1541 descriptor ptr is a facility that allowed a search handler to supply
1542 a socket which would serve as a callback - when search was complete.
1543 This facility has now been in use for years.
1545 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1546 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1547 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1548 returns 'const char *' rather than 'char *. The returned string is
1549 read-only and should not be modified by applications. COMSTACK cs_close is
1550 now a void function - it no longer returns int. No applications check for
1551 the value and the implementations has always returned 0.
1553 ZOOM: use size_t for scan hit counts and str size. Functions
1554 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1555 occ (hit count) and len (string length) are now of type size_t pointer
1556 rather than int pointer. This is to be able to represent large hit counts
1557 and to also just to use the proper type for string length (strlen result).
1559 New JSON parser. Refer to include/yaz/json.h .
1561 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1562 Used to be int in some cases. Many wrbuf_-functions used to return an int
1563 indicating some length.. These return values were never used. And so they
1566 ODR: odr_malloc, odr_total now takes size_t for size.
1568 clone_z_type: fix leak; occurred for encoding failures.
1570 --- 3.0.52 2009/12/03
1572 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1573 bug was introduced in 3.0.51.
1575 --- 3.0.51 2009/12/02
1577 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1579 tcpip comstack: fix leak for getaddrinfo.
1581 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1582 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1583 Decoding of SRU "path" database is performed by private function
1584 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1585 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1587 yaz-client: honor base command for SRU. Change when database setting
1588 is applied for SRU and ensure it is kept when a connection is reset.
1589 Change also the way errors are displayed or SRU (decoding of packages).
1591 --- 3.0.50 2009/11/02
1593 Add support for extra request / response data for SRU codecs and GFS.
1594 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1595 for extra data response buffer and length. For the GFS, both request
1596 and response data (XML) is carried in extra_args and extra_response_data
1597 for the search handler. Patch by Ko van der Sloot.
1599 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1600 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1601 10010). This fixes bug #2113.
1603 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1604 cmdfile included a 'quit' command that would result in a memory violation.
1606 --- 3.0.49 2009/10/01
1608 Make a number of functions defined in xmlquery.c static. These have
1609 never been declared in a public header file (yaz/xmlquery.h) and was
1610 made public by mistake.
1612 Improve speed of character conversions (iconv utilities). This makes
1613 conversions from MARC-8 faster.
1615 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1616 unless type desired is "raw". This will prevent type "xml" from
1617 returning ISO2709 .. Which obviously can not be XML parsed.
1619 Fix memory leak in ZOOM that would occur if option apdulog was used
1620 on a re-used connection.
1622 Frontend server logs HTTP requests.
1624 Frontend server now sends Z39.50 close when it times out (sesssion has
1625 been idle for too long). Versions 2.0.30 and earlier also sent close.
1626 But due to a mistake this was disabled in all versions after that, i.e.
1627 the server would just close the socket immediately.
1629 yaz-client emits a better message when receiving an unrecognised
1630 userInformationField.
1632 Skip zero-length subfields when decoding ISO2709. This rare case happens
1633 if a record has two FS characters in a sequence. Without this patch
1634 there would be a reference beyond char array in using_code_len fragments
1637 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1639 --- 3.0.48 2009/08/28
1641 The show command offered by the zoomsh command now takes a 3d optional
1642 parameter type which is what is passed to ZOOM_record. If the type
1643 argument is omitted, "render" is used.
1645 RPN to CQL conv may use USE string attributes (bug #2978).
1647 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1649 --- 3.0.47 2009/07/08
1651 Function yaz_xml2query allows a diagnostic element in the PQF XML
1652 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1653 code and additional info respectively.
1655 The BER BOOLEAN is now the integral type Odr_bool which still happens
1656 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1657 typedef'd to Odr_int. This is still an integral 'int', but it may be
1658 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1659 ASN-1 compiler as well as programs has been updated to use the new types.
1661 --- 3.0.46 2009/06/08
1663 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1664 only the bibliographic record was rendered. For type=opac, an OPAC
1665 record is only returned if it is present.
1667 iconv: small fix for encoding of advancegreek.
1669 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1671 yaz-client: option auto_reconnect=on really reconnects.
1673 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1675 server: avoid null ptr ref for for yaz_poll errors.
1677 build: fix RPM build for RHEL 5.3.
1679 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1681 --- 3.0.45 2009/03/31
1683 Fixed bug #2709: TCP connect returns Invalid argument.
1685 Fixed compilation for mingw.
1687 Honor charset for raw records (ZOOM_record_get).
1689 Fixed use of errno for threaded mode that was seen on Solaris 10.
1691 Fixed argument passing with blanks in value for Windows Service.
1693 Disable YAZ' own log rotate by default (no 1 GB limit).
1694 The variable l_max_size which specifies the log file limit is set to 0
1695 (DISABLED): This is due to the fact that YAZ is most often deployed using
1696 logrotate. Also YAZ can not perform log rotate because of unsufficient
1697 permissions (setuid).
1699 --- 3.0.44 2009/02/17
1701 List supported encodings in man page for yaz-iconv.
1703 Fixed missing SSL libs for --libs output
1705 Re-established OID record syntax application-xml. Nobody should use it
1706 but we don't want to change soname because of this symbol being absent.
1708 --- 3.0.42 2009/02/02
1710 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1712 Added member named_result_sets for init handler struct for the GFS. This
1713 allows a server to disable named result sets.
1715 Removed OID record syntax application-xml.
1717 Added support for rule-based transliterator for ICU wrapper of YAZ.
1719 Fixed bug #1902: yaz-icu XML output.
1721 Make YAZ checks Emacs friendly.
1723 BITSTRING value shows value. Bug #2346.
1725 ISO2709 decoding: skip control characters from indicator data.
1727 Omit sort key by default in yaz-icu's output.
1729 Allow combined single char options (again) for YAZ' options function.
1731 Utility yaz-marcdump got option to display YAZ version (-V).
1733 Allow YAZ to use ICU 3.4.
1735 Added new ICU test case which illustrates removal of diacritics.
1737 --- 3.0.41 2008/12/29
1739 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1741 --- 3.0.40 2008/12/29
1743 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1746 Fixed bug #2352: yaz-marcdump crashes for certain record.
1748 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1750 Added support for Danmarc2 to UTF-8 conversion.
1752 Added support for ISO5426 to UTF-8 conversion.
1754 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1755 implementation version.
1757 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1759 --- 3.0.38 2008/11/10
1761 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1762 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1764 ZOOM C now interprets databaseName option for ZOOM connection as path
1767 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1769 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1771 Dummy Libxml2 types no longer defined in headers of YAZ'.
1773 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1776 --- 3.0.36 2008/09/26
1778 Various ODR chapter fixes.
1780 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1782 Added missing source for Windows compilation, mutex.c.
1784 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1786 For SRU connections in ZOOM all records up to "count" are now fetched.
1788 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1789 in Windows due to bad error handling for Libxml2.
1791 Added facility for sending arbitrary records (ASN.1 any) using
1792 ZOOM C's Extended service update. Patch by Sam Reynolds.
1794 New options for ZOOM C's connection, logapdu which makes ZOOM log
1797 --- 3.0.34 2008/06/18
1799 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1801 --- 3.0.32 2008/06/12
1803 Fixed memory violation that could occur when decoding UTF-8. This bug
1804 was only present in 3.0.30 of YAZ.
1806 --- 3.0.30 2008/06/06
1808 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1809 GNU TLS is used by default (if found).
1811 yaz-ztest returns OPAC records if a client asks for OPAC.
1813 Improved speed of MARC-8 encoding.
1815 Added support for lossy and loss-less MARC-8 encoding.
1817 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1819 Added new Windows Service wrapper (sc).
1821 yaz-client's itemorder command may now send a file.
1823 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1825 Added new function yaz_log_xml_errors.
1827 Allow (but warn) unknown XML attributes in MARCXML parsing.
1829 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1831 The UTF-8 to MARC-8 conversion now uses a different set of characters
1832 for Greek symbols. Bug #2120.
1834 --- 3.0.26 2008/02/21
1836 Added yaz_daemon (daemon.h).
1838 Fixed bug #2068: pkg-config trouble
1840 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1842 --- 3.0.24 2008/01/28
1844 Document --with-xml2 option.
1846 Added OPAC XML XSD (etc/opacxml.xsd).
1848 Allow glob mask for name attribute in retrieval element for the
1849 generic frontend server's retrieval facility.
1851 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1852 except POLLIN/POLLOUT.
1854 Fixed error handling in cs_listen. Bug #2037.
1856 --- 3.0.22 2008/01/20
1858 Fixed version in yaz/yaz-version.h.
1860 Fixed bug #2027: Crash when closing connection.
1862 Changed configure so that ICU support is only enabled if only ICU
1863 and Libxml2 is available (because the ICU chain is XML based).
1865 --- 3.0.20 2008/01/15
1867 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1868 is built. Only this DLL depends on the ICU runtime.
1870 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1871 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1873 Changed license of CCL module to 'Revised BSD'. After consultation with
1874 remaining members of the original EUROPAGATE consortium, we are re-issuing
1875 the CCL module without a separate license. The software was developed by
1876 Index Data as part of a research project. The special license was included
1877 to help feed usage information back to the project consortium to support
1878 project evaluation. At this time, the project consortium has long-since
1879 disbanded, and the majority of the original principals have retired. At the
1880 same time, we have significantly modified the software during the following
1881 years, to the point where very practically no original code remains. To
1882 simplify re-use of the software, we have contacted those members of the
1883 consortium who could be reached, and agreed to re-issue the module as a
1884 proper part of the YAZ package.
1886 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1888 CQL closer to being version 1.2 compliant. CQL also allows free-form
1889 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1892 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1893 bug could make Extended services handling crash in the ZOOM layer. This
1894 bug was only present in YAZ 3.0.18.
1896 --- 3.0.18 2007/12/19
1898 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1901 yaz-marcdump reads and writes collection wrapped records.
1903 Handle OPAC for record conversion module.
1905 Fixes for ICU wrapper.
1907 Allow ICU libs to be controlled with --with-icu .
1909 --- 3.0.16 2007/11/12
1911 Added yaz_poll which is a wrapper for select/poll. When poll is available
1912 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1913 sockets to be in use.
1915 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1916 functionality through an XML based configuration (ICU chain). This system
1917 is useful for search facilities such as Pazpar2 and Zebra that needs to
1918 perform tokenization of indexed material. The ICU code in a separate
1919 library libyaz3_icu.a.
1921 Added HTTP tunnel facility for COMSTACK, bug #1752.
1922 This is a facility that allows a Web proxy, such as squid, to tunnel
1923 Z39.50 traffic. This facility is "transparent" to must applications
1924 using YAZ. It's enabled by using pseudo transport connect: followed by
1925 the proxy address, followed by command, then follwed by he regular
1926 "virtual" addresss. For example,
1927 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1929 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1931 --- 3.0.14 2007/09/21
1933 Fixed bad memory reference in ZOOM_record - cuased by member not being
1934 initialized. This was a problem only in YAZ 3.0.12.
1936 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1937 fields were not removed.
1939 Changed the way C code is generated from codetables.xml. Made a MARC-8
1940 conversion trie for each characterSet section rather than codeTable.
1941 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1942 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1944 --- 3.0.12 2007/09/12
1946 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1947 from ZOOM_record_error).
1949 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1951 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1953 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1955 Better SRW-to-Bib-1 diagnostic mapping.
1957 ZOOM C and yaz-client announces SRU version 1.2 by default.
1959 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1962 Fixed in yaz_sru_decode to allow other version than 1.1.
1964 --- 3.0.10 2007/08/22
1966 Added support for SRU scan for ZOOM.
1968 Added support for the use of the older versions or Extended Service
1969 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1970 set to the version , 1=first, 2=second, 3=third. The third version is
1971 what ZOOM C has used so far. And that, obviously, is the default.
1973 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1974 therefore in Zebra and in SimpleServer-based applications). The new
1975 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1976 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1977 which is passed into the back-end search callback function.
1979 Added support for HTTP Basic authentication in clients: the SRU/W
1980 codec encodes the username/password elements of the PDU structure
1981 appropriately, and these may be set using the "user" and "password"
1982 options in ZOOM-C applications (the same options that are used for
1983 Z39.50 authentication).
1985 --- 3.0.8 2007/06/25
1987 Fixed bug #1208: SSL appears to be broken in ZOOM.
1989 Fixed bug #1206: Libxml2 include path weirdness.
1991 Added oid_name_to_dotstring.
1993 Allow elementSetName to be specified for ZOOM C record update.
1995 Allow waitAction to be specified for ZOOM C based for Extended Services.
1997 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1998 syntax OID. Bug introduced in YAZ 3 series.
2000 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
2002 --- 3.0.6 2007/06/06
2004 Fixed bug #1157: yaz-client does not read .yazclientrc from current
2005 directory. yaz-client now reads commands from file given by option -f
2006 if specified; then tries to read .yazclientrc in current directory.
2007 Failing that, it reads .yazclientrc from user's home directory.
2009 Added support for correlationInfo Note and ID for Record Update via
2012 Added yaz-client command querycharset which specifies character set for
2013 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
2014 (termListAndStartPoint).
2016 Charset ISO5428:1984 is an alias for ISO5428-1984.
2018 Implemented a way to perform scan in a result set using Z39.50. This
2019 is achieved by attaching the result set name in the characterInfo
2020 (type InternationalString) of OtherInformation in the Scan Request PDU.
2021 The result set is identified in the otherinformation by the new OID:
2022 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
2023 This allows for scan in result set and faceted search . Zebra did some
2024 of this in the APT term using attribute type 8 and value being result
2025 set. Using the OtherInformation approach for this is cleaner and easier
2026 to work with in proxies and the like. This facility can be used in
2027 yaz-client using new command setscan which takes a result set as first
2028 argument, start position (APT) as second.
2030 Changed decoding of SRU XML packed records to deal with servers that
2031 have recordData with XML data with multiple root nodes. Also make
2032 comparison for recordPacking case insensitive. Again, one server
2033 returns "XML" where others return "xml".
2035 For SRU responses allow Content-Type application/xml as well as text/xml.
2037 --- 3.0.4 2007/05/21
2039 Fixed bug in character set conversion of BER strings. Bug introduced
2042 --- 3.0.2 2007/05/08
2044 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
2046 For OID class, use oid_class consistently.
2048 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
2051 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
2052 character set for bibliographic information interchange". By Giannis Kosmas.
2054 Added documentation on new OID API.
2056 --- 3.0.0 2007/05/02
2058 Changes to generic frontend server interface: added new member
2059 'query_charset' for bend_initrequest structure. A backend init handler
2060 should set this member to its native character set for query terms.
2061 When defined, the frontend server logic will announce this character set
2062 to a client if the negotiationModel bit is set by the client. All server
2063 implementors are encouraged to specify this. If a backend server does not
2064 specify this a warning is issued using yaz_log(YLOG_WARN,..).
2066 Added CCL utility to remove terms (stop words) from resulting RPN
2067 tree. This is handled by functions with prefix ccl_stop_words_ .
2069 New ZOOM C option, "rpnCharset", which allows client-side conversion of
2070 terms in RPN queries.
2072 Clean-up the CCL API. Moved some internal structures from ccl.h to
2073 private header cclp.h. Changed ccl_parser_create so that a Bibset must
2074 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
2075 This is replaced by ccl_parser_find_str which takes a string instead.
2077 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
2078 libyaz.la is the core of YAZ except the generic frontend server and
2079 does not depend on POSIX threads anymore. libyaz_server.la is the
2080 generic frontend server facilities and uses POSIX thread functionality
2081 if available. The libyaz.la no longer depends on POSIX threads because
2082 the number of global structures is limited. NMEM no longer re-uses blocks
2083 between threads ; it simply free's memory immediately but allocates in
2084 "large" chunks as usual. We don't expect any performance penalties
2085 because of this. The yaz_log system is still using a global log_level so
2086 caution must be taken when modifying it with yaz_log_init_.. +
2087 yaz_log_mask_str. This, however, should not cause any trouble because
2088 these functions are called during initialization of application code
2089 anyway. `yaz-config --libs server` returns libs for server applications;
2090 `yaz-config --libs` returns libs for non-server applications.
2092 New OID database - with public definitions in oid_db.h. Removed old OID
2093 database including the head oid.h and definitions such as enum oid_value
2094 and struct oident. The new OID database uses the same string names as
2095 before but the 'protocol' is gone. There are now only two representations
2096 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
2097 converts from string to OID; functions with prefix yaz_oid_to_string
2098 converts the other way.
2100 Change to emit_term() in CQL-to-PQF query translation: when a term has
2101 the /regexp relation modifier, do not process it for leading and
2102 trailing "^" and "*", which have quite different meanings in regular
2105 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2106 write handlers no longer carries a 'last' parameter. This will make
2107 yaz_iconv flush "less" characters. A flush is performed by call to
2108 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2110 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2111 removed, because function yaz_query_to_wrbuf does the same.
2113 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2114 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2116 Deprecated MARC utility functions removed.
2118 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2121 Branch split: YAZ_2_1_55_branch
2123 --- 2.1.54 2007/03/16
2125 Fix to ZOOM-C so that transparent reconnection is properly handled on
2126 connections that are in asynchronous mode.
2128 Fixed compilation on OpenBSD 4.0.
2130 Large strings in GRS-1 records are now properly displayed in yaz-client.
2132 Added character conversion support for "advancegreek"; based on patch from
2135 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2136 sequence is met. Before the error was not set so it would be unknown.
2138 Adjust yaz-marcdump MARC reader so that it skips until record separator
2141 --- 2.1.52 2007/03/07
2143 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2144 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2145 fd_set structure used as a bitmask for the FDs to be selected on.
2147 Using ACX_PTHREAD macro to check for POSIX threads.
2149 Fixed have-vsnprintf check.
2151 --- 2.1.50 2007/02/23
2153 Fixes for configure on BSD. Bug #900.
2155 Added snprintf/vsnprintf wrappers for systems that don't have
2156 limits (heavens forbid).
2158 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2159 created before all previous tasks were completed and removed from the
2160 task queue, the new task could be removed by a mistake.
2162 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2164 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2166 Fixed bug #832: Problem with MARC/charset in yaz-client.
2168 Fixed bug #668: save command line history for yaz-client.
2170 Fixed bug #830: pkg-config support.
2172 --- 2.1.48 2007/01/23
2174 Extended ZOOM result set options with two options that may be read by
2175 a client: resultSetStatus and presentStatus with values as specified for
2177 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2179 Fixed bug #827: Using SSL fails on Debian etch.
2181 Fixed bug #826: Weird looking chars for set of MARC records.
2183 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2184 that is treated as an ItemOrder with itemRequest being an XML document
2185 external. The value of "doc" is the content.
2187 Extended the GFS search facility. New member of bend_search_rr
2188 'estimated_hit_count' signals that hits is known to be an estmate
2189 (higher or lower than real hit count). New member 'partial_resultset'
2190 signals that the search was partial (hit count is lower or equal than
2191 real hit count). For Z39.50, the information is stored in resultSetStatus
2192 member of SearchResponse APDU. For SRU, the information is signalled
2193 via SRU diagnostic 59: "Result set created with valid partial results
2196 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2198 --- 2.1.46 2007/01/13
2200 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2202 Added ZOOM_connection_peek_event.
2204 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2205 the following new functions:
2206 ZOOM_event_nonblock, ZOOM_connection_process,
2207 ZOOM_connection_get_{socket,mask,timeout},
2208 ZOOM_connection_fire_event_{timeout,socket}.
2209 The existing blocking event handler, ZOOM_event, is a wrapper for the
2210 + blocking ZOOM_event_sys_{poll,select}.
2212 Implemented function ccl_xml_config which parses XML version of CCL
2213 configuration (bug #798).
2215 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2217 Added timings utility (yaz/timing.h)
2219 --- 2.1.44 2007/01/03
2221 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2224 Fixed bug #779: Rotation of apdu.log fails.
2226 Fixed for character set conversions:
2227 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2228 Honor G1 set in MARC-8 decoding.
2230 --- 2.1.42 2006/12/17
2232 Fixed bug #775: char conversion does not handle Alternative UTF-8
2235 Implemented function yaz_marc_read_line which parses MARC line format
2236 records. There is a wealth of formats out there. So far, this function
2237 reads line records produced by yaz_marc_write_line.
2239 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2240 more generic and easier to remember(!) options: -i format and -o format
2241 which specifies input format and output format respectively - where
2242 format is one of "marc", "marcxml", "line", "marcxchange".
2244 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2245 does not print anything except warnings for records.
2247 For yaz-marcdump, added support for MARC split into files (-s) with a given
2250 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2251 spec, at http://www.loc.gov/standards/sru/record-update/
2252 This has changed the binary layout of the following structs:
2253 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2254 bend_update_rr . Patch by Ko van der Sloot.
2256 Added GFS utility function bend_assoc_is_alive which returns 1 if
2257 association is still alive (client is connected); 0 otherwise (client
2258 closed connection). This allows busy servers to stop working for
2261 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2262 been a separate piece of software. This version of ziffy has been modified
2263 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2265 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2267 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2268 Client code may now interrogate options such as "init_opt_sort" to
2269 find out whether the server claims to support various options.
2271 --- 2.1.40 2006/11/27
2273 Added utilities yaz_{set,get}_esn to set/get element set name from
2276 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2277 of YAZ and has been so since YAZ 2.1.10.
2279 Implemented ZOOM_record_error which returns error information for
2280 record (surrogate diagnostic).
2282 --- 2.1.38 2006/10/31
2284 Updates for SRU Update by Ko van der Sloot:
2285 1. Changed name from "operation" to "action"
2286 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2287 versions in the code, marked as 'backward compatible'.
2288 3. Added diagnostics for SRU Update.
2290 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2292 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2294 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2296 For GFS, fixed problem with SRU diagnostic 'First record position out of
2297 range' being issued for 0 hits.
2299 zoomtst10 part of Windows Build.
2301 --- 2.1.36 2006/10/13
2303 Implemented yaz_filepath_comp which splits a path into file path
2304 components (required by Zebra 2.0.3+).
2306 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2307 BSD inspired license until now so this should not have any real impact on
2308 anybody. See http://www.opensource.org/licenses/bsd-license.php
2310 Fixed bug #687: Missing log lines.
2312 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2315 Fixed bug #689: SRU diagnostics to be added.
2317 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2318 whether a connection is idle (no more work do do).
2320 --- 2.1.34 2006/10/04
2322 Change type of optval from long to int for invocation of setsockopt with
2323 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2325 Added support for specifying the max log file size for the Generic
2326 Frontend Server. The size is given with option -r.
2328 --- 2.1.32 2006/09/21
2330 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2332 --- 2.1.30 2006/09/17
2334 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2337 Fixed bug in Generic Frontend Server that could cause a server to stop
2338 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2340 For the generic frontend server, the maximum record size is used as maximum
2341 size of incoming packages (SRU + Z39.50). The value until was previously
2342 only used in Z39.50 Init negotiation and, later, in a session controlled
2343 sizes of records returned. This is controlled using -k option. It can be
2344 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2346 --- 2.1.28 2006/09/04
2348 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2351 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2353 New option for yaz-marcdump -lpos=value which allows setting a portion
2354 of MARC header to a certain value.
2356 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2358 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2359 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2361 --- 2.1.26 2006/08/15
2363 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2366 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2368 --- 2.1.24 2006/08/08
2370 Fixed MARC ISO2709 encoding routines to deal with character set
2373 Minor changes to GFS logging. Database included in search request log
2376 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2377 cached/multiple records.
2379 Shared libraries are built by default on Unix+configure.
2381 Changed cql2pqf transformation to use a different evaluation order. The
2382 new order is: always, relation, structure, position, truncation, index
2383 and relationModifier. Old order was: always, relation, relationModifier,
2384 structure, index, position, truncation. Note that the the latter ones
2385 override former ones for identical attributes.. The new scheme means that
2386 it is possible to override any existing attribute with a relationModifier.
2387 And also that it is possible to override everything for the index rule
2388 (except the ones listed in relationModifier). No order is perfect but this
2389 one, we believe, covers more real cases.. The "always" should have been
2390 called "default", since the attributes there can be overridden with all
2393 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2394 compilation phase, but also for yaz-config --cflags output. This allows
2395 us to have public headers with Libxml2 stuff in them . It should also,
2396 eventually, make Libxml2 checks redundant in packages using YAZ, such
2399 --- 2.1.22 2006/06/15
2401 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2402 stored in uri, message and details.. Previously diagnostics were stored
2403 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2404 compatibility.. but he's probably the only one affected, so.
2406 Added support for CCL, compiled on the client side, in ZOOM-C. This
2407 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2408 input; the resulting query objects can be used for for searching with
2409 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2411 YAZ' configure searches for OpenSSL by default.
2413 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2414 SL_CTX_use_certificate_file. See
2415 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2416 for more info. Thanks to Ko van der Sloot.
2418 --- 2.1.20 2006/06/02
2420 Bug #600: SRU GET, POST support for yaz-client. Introduced
2421 command 'sru' which selects method SOAP/GET/POST.
2423 Allow missingValueAction to be specified for the sortspec string -
2424 function yaz_sort_spec. By default, the missing value action is null.
2425 Use ! to specify "abort". Use = followed by stringvalue to specify default
2428 Ensured that Present-handler (if defined) is called in GFS before any call to
2429 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2430 searchRetrieve requests.
2432 Documentation for YAZ is now based on the Docbook XML/XSLT using
2433 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2434 is no longer depending on jade/openjade or docbook-to-man scripts.
2435 PDF is no longer part of the distribution - but can optionally be
2436 made using DSSSL/jadetex or FOP.
2438 Added retrieval handling support in Generic Frontend Server to support
2439 conversion between MARC/XML as well as XSLTtransforms. See
2440 etc/yazgfs.xml for an example.
2442 Added Authentication support to Generic Frontend Server in SRU
2443 mode. Authentication using HTTP Basic is supported, as is the use
2444 of 'x-username' and 'x-password' parameters in the request itself.
2446 Added support for a new character set MARC8s identical to MARC8 except
2447 that it converts combined characters to single Unicode characters in the
2448 Latin-1 range (when possible).
2450 --- 2.1.18 2006/04/24
2452 ASN.1 compiler 0.4: generates brief Doxygen file header for
2453 generated .h/.c files.
2455 Utility yaz_iconv now supports conversion to MARC-8.
2457 New facilities for the MARC module. The reading - and writing of
2458 content are separate methods for the yaz_marc_t handle. The following
2459 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2460 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2461 format). Write functions have prefix yaz_marc_write_.. The existing
2462 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2463 available. Removed support for OAI-MARC and simplexml (not the
2464 simplexml from PHP5).
2466 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2467 to be returned for this connection.
2469 --- 2.1.16 2006/03/31
2471 Allow multiple languages and charsets to be specified with
2472 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2473 negcharset iso-8859-1,utf-8
2475 Translation of proximity nodes from CQL into PQF now works.
2477 Moved to automake 1.8, 1.9.
2479 Added function yaz_log_set_handler which allows a log handler to be
2480 installed. This handler will be called for all log messages. Output
2481 to file is also produced; but that can be disabled by passing NULL
2482 fname to yaz_log_init_file.
2484 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2486 For SRW (including GFS), accept application/soap+xml as content-type
2489 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2490 produces NO stylesheet reference even if a default stylesheet is specified
2493 --- 2.1.14 2006/03/14
2495 Updated Windows package to include yazd.dll + yazd.lib for the
2496 Development component.
2498 If the environment variable YAZ_LOG is set, then it is used as a
2499 string indicating the default level of logging to use if not
2500 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2501 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2502 used as before. So, for example, to omit warnings from YAZ logging,
2503 export YAZ_LOG=-warn
2505 cql_transform() now map structure and other attributes before indexes,
2506 so that index-specific structures and other attributes can override
2507 defaults. So now a combination of mapping specifications such as:
2509 index.dc.date = 1=date-modified 4=5
2510 does the right thing.
2512 cql_transform() now also respects the "always" mapping specification,
2513 which establishes an initial set of attributes to be used for all
2514 terms except where overridden by more specific attributes associated
2515 with the index, relation or modifier.
2517 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2518 which mode to use; one of "post", "get" or "soap" (SRW, default).
2520 Fixes for yaz_iconv routines: changed trie-based character set conversions
2521 to use only non-negative values for bit fields due to Sun's C compiler not
2522 supporting negative values.
2524 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2525 sequences where not read correctly. Fix by Rustam Usmanov.
2527 Updated win/makefile to use options, settings which makes things
2528 compile with VS C 2005.
2530 --- 2.1.12 2006/02/01
2532 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2534 In ZOOM socket code, use select instead of poll on MacOSX.
2536 ZOOM-C now support client-side compilation of CQL into RPN that is
2537 sent to the server, enabling CQL to be used against all Z39.50
2538 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2539 ZOOM_query object, and submit it using ZOOM_connection_search().
2540 The CQL-to-RPN translation uses a configuration file, the name of
2541 which must be specified in the Connection's "cqlfile" option.
2543 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2544 function, which takes as its start-term parameter a ZOOM_query object
2545 (which may have had either CQL or RPN set into it).
2548 --- 2.1.10 2005/11/29
2550 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2551 GFS to support this as well. Backend handler, bend_srw_update, does the
2552 update work. Code contributed by Ko van der Sloot.
2554 Allow retrieval of Search Result-1 information in ZOOM by the use of
2555 options that are attached to a result set. ZOOM documentation updated
2558 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2559 UTF-8 conversion. Patch by Raj Patel.
2561 Added option -m to GFS to control formatting of timestamps in log file.
2563 Added 'exit' as synonym for 'quit' in yaz-client
2565 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2566 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2567 for the new members. Patch by Ko van der Sloot.
2569 Added support for SRU POST. It is supported for content-type
2570 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2572 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2573 Instead make the library libyaz.la multi-threaded. Threading as a whole
2574 can still be disabled by configure option --disable-threads. Previosly,
2575 with older GLIBCs there were problems with MT libs under Apache. This
2576 has now been fixed a long time ago.
2578 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2581 CQL module modified to be case insensitive for relations/indexes/operations.
2583 Fixed bug in CQL transform code: incorrect value relationModifieder
2586 Added 'show all' command for yaz-client which retrieves all results
2589 Added new yaz-client, xmles, which takes a (private) OID and
2590 a document to be sent as an extended service request.
2592 Describe new yaz-client commands wait_response and set_auto_wait.
2594 Increase TCP/IP listener backlog from 3 (which I am guessing was
2595 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2596 that the socket will queue as many incoming connections as it's able
2597 to handle ongoing connections. In other words, it will never now
2598 refuse a connection that it would be able to handle merely because
2599 it's not got around to accepting() enough of the pending connections
2600 yet. This is the behaviour anyway under Linux, where the listen()
2601 argument is ignored; but not under BSD and on systems such as
2602 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2603 YAZ-based servers should now be uniform across operating systems in
2606 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2607 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2608 This allows yaz-marcdump to read large MARC batches (>2 GB).
2610 Modified all YAZ source files - except the source which is auto-generated
2611 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2614 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2615 corresponding to the existing *_setl() function. These allow option
2616 values containing arbitrary valuues.
2618 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2619 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2620 except that it returns an indicator of whether or not the sort
2621 criterion was accepted (0 for OK, -1 for invalid).
2623 --- 2.1.8 2005/06/07
2625 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2626 MARC output rather than returning "new" buffer.
2628 yaz-client warns about unknown init options.
2630 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2632 --- 2.1.6 2005/05/24
2634 Added support for SRW sort in Generic Frontend Server. Patch
2635 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2636 sortKeys - or NULL if none is provided.
2638 Fixed bug #307: It was impossible to specify indefinite/no timeout
2639 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2642 Added support for multiple languages and charsets to be specified in
2643 ZOOM. Each charset/language is separated by a blank. If negotiation is
2644 in effect in init-response, Option
2645 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2646 Code based on patch by Vasiliy Osadchuk.
2648 Fixed bug #306: infinite recursion that occurred when calling
2649 yaz_log_level_init as the first call (before other log level or
2652 Fixed bug in scan handling in front end server: if preferred-Position-In-
2653 Response was non-present, a NULL pointer referece was performed.
2655 --- 2.1.4 2005/04/26
2657 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2658 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2659 now defined for all those error codes. So instead of putting 109 in
2660 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2661 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2663 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2666 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2668 Program yaz-client now exits and produces an error message if multiple
2669 Z39.50 servers are specified on the command line (none or one allowed
2672 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2675 --- 2.1.2 2005/03/16
2677 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2679 Fixed bug #272: Preserve spacing for CCL terms.
2681 --- 2.1.0 2005/03/14
2683 Added support for virtual hosts and multiple backend servers for
2684 the YAZ frontend server. The configution is XML based and
2685 support specificition of CQL to RPN mappings and explain information.
2686 See section "Virtual Hosts" in the YAZ manual.
2688 Extended OPAC display utility. OPAC display utility renders
2689 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2690 to supplement yaz_marc_decode_wrbuf.
2692 Fixed a bug in MARC decoder that could caused it to crash for some
2693 invalid MARC records. More diagnostics and warnings where added in
2694 XML output (warnings, etc are stored in comments).
2696 --- 2.0.34 2005/02/08
2698 Fixes for UNIX domain sockets. Bug #261.
2700 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2702 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2703 Added yaz_marc_subfield_str which defines subfield lead string which is
2704 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2705 yaz_marc_endline_str which defines end of fields string used in
2706 YAZ_MARC_LINE format. Default string is newline.
2708 Experimental support for MarcXChange. This format can be produced
2709 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2710 http://www.bs.dk/standards/MarcXchange.xsd
2712 Added yaz-client commands scansize that sets maximum number of
2713 entries to be returned by scan.
2715 --- 2.0.32 2005/01/11
2717 Added support for SRW scan in yaz-client and Generic Frontend Server.
2719 * Added whereInList member to SRW Scan Term.
2721 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2723 Fixed NMEM system to return aligned blocks on the smallest boundaries
2724 that are suitably aligned for all possible types on the particular
2725 architecture YAZ is being built for.
2727 --- 2.0.30 2005/01/04
2729 Fixed numerious warnings that was issued with newer versions of GCC.
2731 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2732 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2735 Make YAZ Generic Frontend Server slightly faster.
2737 Enhance (and reduce) logging for Generic Frontend Server.
2739 Revert YAZ log system so that it flushes every write operation
2740 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2742 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2743 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2744 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2745 will effectively disable old definitions.
2747 --- 2.0.28 2004/11/09
2749 Added yaz_log_time_format which specifies log format using
2752 Added yaz_log_module_level which returns mask for a module. Value
2753 is non-zero mask a if module is enabled; zero if disabled.
2755 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2756 in include/yaz/cql.h.
2758 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2760 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2762 Fixed bug #172: RPM builds does not enable SSL.
2764 Doxyfile.in part of dist. Doxyfile generated by configure.
2766 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2767 are given and the corresponding component does not exist.
2769 Extend CCL documentation in YAZ reference. Describe r=r.
2771 --- 2.0.26 2004/10/01
2773 Fixed MARC->MARCXML conversion to properly deal with
2774 fields, subfields, indicators having non-ASCII characters.
2776 Fixed MARC->MARCXML conversion so that ASCII control characters
2777 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2780 Added YAZ GFS support for conversion from Z39.50 surrogate
2781 diagnostics to SRW surrogate diagnostics.
2783 Bug fix: YAZ GFS did not return schema in explainResponse.
2785 --- 2.0.25 2004/09/30
2787 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2788 now converts recordSchema to elementSetName as well as schema URI.
2790 Fixed bug in COMSTACK that prevented HTTP request packages from being
2793 --- 2.0.24 2004/09/29
2795 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2796 does not require white-space before and after the dash in a range, e.g.
2797 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2800 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2801 due to new GCC removing "redundant" code.
2803 Added yaz-client commands scanpos and scanstep that sets preferred
2804 position and step-size for scan.
2806 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2808 Added CCL utility ccl_qual_buf which parses one or more CCL
2809 spec lines in a buffer.
2811 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2812 of name and value - ignoring empty lines and comments.
2814 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2816 Added odr_get_element_path which returns current element path for an
2817 ODR handle. This utility is useful in error handling or user-defined
2820 Added ODR_PRINT utility odr_set_stream which is is a more generic
2821 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2822 to a write function and pointer to close function. The close function - if
2823 non-NULL - will be called during odr_destroy.
2825 Fixed bug in CCL parser where truncation char was not removed from
2826 right side when truncation=both was in effect.
2828 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2831 --- 2.0.23 2004/08/11
2833 Fix buffer overrun in CQL parser when dealing with proximity (%).
2835 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2836 to UTF-8/UCS conversion is now only based on codetables.xml.
2838 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2840 --- 2.0.22 2004/08/06
2842 Add support for more "commit changes" in ZOOM (uses Extended Services).
2844 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2847 Yet another small fix for configure of SSL.
2849 --- 2.0.21 2004/05/14
2851 Fix SSL libs for configure when --with-openssl=DIR is given.
2853 --- 2.0.20 2004/05/10
2855 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2857 SSL comstack now uses yaz.pem certificate file on server side
2858 by default. Certificate filename can be configured by calling
2859 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2861 Fix bug regarding multiple calls to ZOOM_connection_connect.
2863 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2865 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2866 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2868 ZOOM now allows inspection of X509 peer certificate for verification.
2869 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2871 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2872 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2873 as "modular" but it simplifies things.
2875 Added cs_get_peer_certificate to that returns peer X509 PEM.
2877 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2878 NULL if SSL is unavailable.
2880 Documentation about MARC decoding tools.
2882 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2884 --- 2.0.19 2004/03/30
2886 Rename CHANGELOG to NEWS to follow GNU style packing.
2888 Fix bug with missing initialization of member in init_diagnostics.
2889 This bug affects threaded version of GFS server.
2891 --- 2.0.18 2004/03/20
2893 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2896 Ensure zlib.dll is packed with Windows install.
2898 --- 2.0.17 2004/03/17
2900 Fix encoding of xsd:string to use text instead of CDATA.
2902 Fix endless loop in CQL parser with unbalanced ".
2904 Use a more compact way to store MARC-8 conversion tables.
2906 --- 2.0.16 2004/03/16 Debian only
2908 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2911 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2916 --- 2.0.15 2004/03/01
2918 Another fix for decoding of XML packed records.
2920 --- 2.0.14 2004/02/25
2922 Fixes for Chunked encoding. White space not ignored after length spec.
2924 Update NS and use default NS for SRW diagnostic elements.
2926 --- 2.0.13 2004/02/23
2928 Implement ZOOM_resultset_cache_reset which resets record cache.
2930 Implement ZOOM_resultset_sort which sorts a result set.
2932 Implement chunked HTTP transfer.
2934 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2936 --- 2.0.12 2004/02/16
2938 Added member 'schema' to bend_explain_rr structure so that backend
2939 can specify explain record identifier. Defaults to Zeerex 2.0.
2941 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2943 --- 2.0.11 2004/02/16
2945 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2948 Added init command for yaz-client which sends "extra" init request.
2950 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2951 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2953 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2955 Make ZOOM error code for "invalid query".
2957 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2959 --- 2.0.10 2004/02/05
2961 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2964 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2966 Added option -p <file> to make Generic Frontend Server to write PID file.
2968 Added option -D to put Generic Frontend Server in background on its own.
2970 Make ZOOM C recognize option "password". If unset, "pass" is used
2971 (for backwards compatibility).
2973 Fixed a bug in Generic Frontend Server that could make it crash if a
2974 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2977 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2978 Must be issued before open, in order to be in effect.
2980 --- 2.0.9-6 2004/01/12 Debian/Windows
2982 Make the SRU server more picky WRT unknown params, etc.
2984 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2986 New YAZ client command, options, that sets Z39.50 options.
2988 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2989 options from a string of tokens (one token for each option bit).
2991 Update SRW diagnostic code messages.
2993 --- 2.0.9-5 2004/01/07 Debian/Windows
2995 Handle user defined stylesheet for SRW/SRU.
2997 --- 2.0.9-4 2004/01/06 Debian/Windows
2999 Fix bug in decoding of Content-Length.
3001 --- 2.0.9-3 2004/01/06 Debian/Windows
3003 Fix a bug with decoding of XML packed records.
3005 --- 2.0.9-2 2004/01/05 Debian only
3007 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
3009 Fix bug in SRW/SRU diagnostics decoding.
3011 --- 2.0.9 2004/01/05
3013 Fixed bug in Generic Frontend Server which could drop records exceeding
3014 preferred message size. Reported and fixed by Irina Dijour.
3016 Fixed calculation of package size for structured records in Generic
3017 Frontend Server. Reported and fixed by Irina Dijour.
3019 Fixed namespace for SRW/SRU diagnostics.
3021 Fixed SEGV in yaz-client that occured for HTTP connection errors.
3023 --- 2.0.8 2003/12/22
3025 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
3026 this version is incompatible with version 1.0 and older YAZ SRW/SRU
3029 CQL changes to reflect recent changes to the specification:
3030 * Documentation talks about context sets instead of index sets.
3031 * Documentation talks about indexes instead of qualifiers.
3032 * The CQL-to-PQF transformer's configuration file now uses
3033 "index.set.name = <attributes>" instead of the old form
3034 "qualifier.set.name = <attributes>". (Both forms are still
3035 understood but the latter is deprecated.)
3036 * CQL terms with no explicit index specified are now interpreted as
3037 cql.serverChoice instead of srw.serverChoice (which of course
3038 behaves exactly the same.)
3040 --- 2.0.7 2003/12/16
3042 MARC conversion can now generate ISO2709 output in another
3043 character set. yaz-marcdump uses this facility if you invoke it
3046 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
3047 functions from there can be used from C++.
3049 --- 2.0.6 2003/12/04
3051 Frontend server now transfers memory from decoded packages to stream
3054 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
3055 references to show up.
3057 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
3058 the ZOOM Abstract API. The older names for the same options are still
3059 also supported for the benefit of old applications.
3061 ZOOM-C supports "implementationId" and "implementationVersion" options
3062 to go along with "implementationName". These allow the user code to
3063 specify identification strings to be sent to servers.
3064 Add OID for the new ExtLite attribute set.
3066 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
3067 as requested/supplid by Ere Maijala <ere@atp.fi>
3069 For generic frontend server, reverse the order of
3070 "toolkit-supplied / application-supplied" strings sent as implementationId,
3071 Name and Version. Also, remove the spaces around the slash. This brings
3072 the GFS in line with the behaviour of ZOOM-C on the client side.
3074 Add function ZOOM_scanset_display_term.
3076 yaz-client shows scan displayTerm if present.
3078 Utility yaz-iconv is now installed by default along with the man page
3081 Extend configure check for OpenSSL to use pkg-config where available (such
3084 Incorporate patch by Morten Bogeskov which allows a Unix file socket
3085 server to specify uid/gid/mask for socket using the format
3086 unix:[user=uid,][group=gid,][umask=mask,]file=path
3087 If file= is omitted the existing format is assumed, e.g.
3089 in which case the mask is 0666 (rw for everybody).
3091 Major restructure of YAZ source. All source in libyaz is in src directory.
3092 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
3093 util (utility programs such as ASN.1 compiler, yaz-marcdump).
3095 Added man page for utility yaz-marcdump (used to be called marcdump).
3096 yaz-marcdump is installed by 'make install'.
3098 Fixed a memory leak in Generic Frontend Server that occurred when decoding
3099 of incoming package failed.
3101 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
3103 Change prototype of odr_perror: add const to message string.
3105 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
3107 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
3108 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3109 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3110 DNS lookup. There should not be any compatibility problems with this
3111 assuming that blocking=1 or 0 is used.
3113 Fix bad reference in UNIX comstack in function cs_addrstr.
3115 Fix for compilation on AIX.
3117 The generic front-end server (server/seshigh.c) now supports returning
3118 Init diagnostics to the client in User-information-field, in
3119 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3122 --- 2.0.4 2003/09/04
3124 Allow any CQL relation (not just all,any,exact,scr).
3126 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3127 that features the same UI.
3129 Implemented command update0 in YAZ client which is equivalent to
3130 update but uses old of Ext Update ASN.1.
3132 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3133 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3134 Previously no OID was used for this info.
3136 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3137 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3138 returns 'malformed search term' otherwise.
3140 SortResponse member resultCount now set to NULL in sort handler of
3143 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3146 Add three new utility functions for translating OIDs between various
3147 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3148 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3149 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3150 char *oid_to_dotstring(const int *oid, char *oidbuf);
3151 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3153 Reverted modifications for ES Update definition for z_IU0Update
3154 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3155 is back to YAZ 2.0.2.
3157 String value attributes for CCL parser.
3159 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3160 which their FirstSearch server returns in Init responses, sometimes
3161 carrying useful diagnostic information when Init fails. This has the
3162 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3163 "z39.50/oclcui.asn", where its definition is somewhat different from
3164 what OCLC document on their web-site, as required to interoperate with
3167 Support for anonymous authentication in yaz-client. Use the command
3170 * Fix the OID of the Index Data-local "admin" Extended Service from
3171 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3172 the 1000, which indicates a locally-defined OID, was a mistake.
3174 --- 2.0.3 2003/06/20
3176 Fix CCL directive @case handling so that it affects string match for
3177 both CCL keywords and qualifiers.
3179 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3180 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3181 Decoder has been updated with ASN.1 changes as listed in
3182 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3183 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3184 z_IUUpdate, remains unchanged.
3186 ZOOM_record_get may now return a record in a specific character set.
3187 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3188 "from" is the character set of record as returned by target. "to" is
3189 the character set to be returned. If omitted, "to" is UTF-8.
3191 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3193 New ODR utility, odr_getelement, which returns name of element for
3194 which encoding/decoding failed.
3196 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3197 in cases where a required element was omitted.
3199 Bug fix: some MARC8 sequences were not converted.
3201 New ZOOM option "step" which specifies number of records to be
3202 retrieved in one chunk. Used in conjunction with "start" and "count".
3204 SRW support for yaz-client. Use scheme http: to use it, e.g.
3207 yaz-client no longer does (un)intelligent character set conversions
3208 by default. Can be enabled with charset and marc_charset commands.
3210 xmalloc trace fix for 64-bit systems such as DEC alpha.
3212 Solaris 2.6 compile fix.
3214 New function, cql_strerror() translates SRW error codes, as returned
3215 by cql_transform_error(), into human-readable English strings. Used
3216 in yaz-client diagnostics when appropriate.
3218 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3219 converts it into a type-1 query which is sent to the server. This
3220 makes CQL available for use with all Z-servers, as opposed to the tiny
3221 minority that can handle CQL queries themselves.
3223 --- 2.0.2 2003/04/28
3225 New Debian package layout similar to the Redhat Package layout.
3227 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3228 and search result respectively.
3230 --- 2.0.1 2003/04/25
3232 Redhat package is now several packages: libyaz (runtime libraries),
3233 libyaz-devel (development and documentation, and yaz (utility programs).
3234 Package spec file by Morten Bogeskov.
3236 New member 'schema' in struct bend_fetch_rr which the name of requested
3237 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3238 handler MAY set this to reflect the schema of the returned record.
3240 New member 'display_term' in struct scan_entry. GFS now sets member entries
3241 and allocates scan entries to be filled by user scan handler. In previous
3242 version, entries member was allocated by the scan handler. That still works,
3243 but the GFS will ignore member display_term - assuming it was NOT set by
3244 the handler. The fact that the GFS now allocates the entries both allows
3245 for new members and makes a scan handler easier to write.
3247 Fix CQL lex buffer overflow.
3249 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3250 SRU default recordPacking is string.
3252 SRU protocol support for frontend server.
3254 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3256 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3258 Added scan for the ZOOM shell (zoomsh).
3262 * String Identifers for Schemas (Amendment 5).
3263 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3264 Old definition for schema
3265 Odr_oid *schema; /* OPT */
3270 Z_InternationalString *uri;
3271 #define Z_Schema_oid 1
3272 #define Z_Schema_uri 2
3275 * resultCount parameter to Sort Response (Amendment 1).
3276 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3278 Support for SRW 1.0 over HTTP. This is an optional feature and
3279 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3282 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3283 on the same port. SRW SearchRetrieveRequests are mapped
3284 to bend_init,bend_search,bend_fetch,bend_close.
3286 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3288 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3289 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3291 ZOOM connections are SRW based if schem http is used for hostname
3292 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3293 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3295 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3296 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3297 distance=n, order=true/false, relation=le, prox unit=word. If
3298 n is omitted, distance 1 is used.
3300 Fixed problem with C compiler include path in wrong order.
3302 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3303 on Solaris. Patch from Ko van der Sloot.
3305 New MARC decode API. All new functions operate on a yaz_marc_t
3306 handle. The most important new functions are: yaz_marc_create,
3307 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3308 decode and destroy respectively. Decoder can produce formats
3309 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3310 include/yaz/marcdisp.h.
3312 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3313 to UTF-8, UCS-32, wchar_t or Latin-1.
3315 * Prototypes for yaz_iconv_-functions moved to separate header
3316 include/yaz/yaz-iconv.h.
3318 Make a few private functions 'static' in unix.c. This prevents
3319 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3321 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3322 are set when Init Response is received.
3324 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3325 but returns diagnostic set as well.
3327 New function yaz_strerror which is a portable wrapper for
3328 strerror/strerror_r/GetLastMessage.
3330 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3331 is returned for MARC. If type is "oai", then OAI MARC is returned.
3333 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3336 --- 1.9.2 2002/11/26
3338 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3340 Fix bad race conditions on SIGTERM and terminate gracefully in
3343 Move retrieval (data1) module to Zebra since nobody seems to be
3346 Add GRS-1 render for ZOOM using same format as yaz-client.
3348 --- 1.9.1 2002/10/05
3350 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3352 Fix broken ESpec handling in data1 module.
3354 SGML reader parses comments and makes them part of the data1 tree.
3356 Added several type casts so that YAZ compiles as C++ code.
3358 ZOOM didn't handle PDU encoding failures properly.
3360 Added more Bib-1 diagnostics (approved extensions).
3362 GNU configure: better check for iconv.
3364 More portable use of accept, getpeername. Check for socklen_t. Use
3365 int/size_t if socklen_t is not defined.
3369 PQF parser rejects bad queries - including those with extra
3370 characters in them. PQF parser used to silently ignore that.
3371 Cleaner API for PQF added, which allows you to get detailed
3372 error information for bad queries (see yaz/pquery.h).
3374 Fixed bug in ZOOM_record_get for type "database".
3376 Implemented mini iconv library supporting conversions between
3377 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3379 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3381 --- 1.8.9 2002/08/20
3383 Fixed ZOOM C record cache so that preferredRecordSyntax and
3384 elementSetName is used to check for already fetched records.
3386 --- 1.8.8 2002/08/02
3388 Added three members in bend_initrequest structure to facilitate
3389 character set negotiation.
3391 Fixed a bug in frontend server that could cause indefinite
3392 loops under rare conditions.
3394 Revised character set utilities (charneg.h) so that encoding
3395 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3397 For PQF, directive @term <type> sets term type for Scan/Search.
3398 Here <type> is general, string, numeric, null. The term type
3399 is inherited - just like @attr.
3401 New call odr_set_charset that sets character set conversion for
3402 international-strings on a ODR stream. Prototype is:
3403 int odr_set_charset(ODR o, const char *to, const char *from);
3404 The InternationalString is still represented as C string in YAZ
3405 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3406 won't). On the protocol level, you can use any encoding.
3408 Support for UNIX sockets in ZOOM.
3410 Solaris recv sometimes returns errno == ENOENT. It is treated as
3411 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3413 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3414 both client and server. Code by Morten Bogeskov.
3416 --- 1.8.7 2002/05/22
3418 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3419 that they can be used directly from Visual Basic. You must recompile
3420 your windows APP if you're using ZOOM.
3422 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3423 Commands "lang" and "charset" sets language and character set respectively.
3424 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3425 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3427 Attributes from multiple CCL fields may be OR'ed rather than merged
3428 using directive "@field or". Fields are still merged by default -
3429 equivalent to "@field merge".
3431 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3434 Fixed bug in zget for parameter ExtendedServicesResponse.
3438 --- 1.8.6 2002/03/25
3440 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3442 Client displays USR.1:SearchResult-1 (hits per term).
3444 Additional Search Info for search in Generic Frontend Server.
3446 Fixed CCL parsing of "field=s".
3448 WIN32 installer - using the excellent NSIS software from nullsoft.
3450 Fixed CCL parsing of "field = - <number>".
3452 Added function yaz_marc_decode that decodes MARC for line mode
3453 display or XML (similar to that used by JZKit).
3455 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3456 Z39.50. But ISO/ILL was, however.
3458 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3459 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3461 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3462 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3464 --- 1.8.5 2002/02/03
3466 New YAZ client features: Command completion and new commands:
3467 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3468 Code provided by Jacob Poulsen.
3470 New call oid_trav, that visits all registered OIDs via callback.
3472 Function ZOOM_record_get now returns const char pointer rather than
3473 void pointer. It saves a lot of type casts.
3475 For YAZ client, command "auth" now allows you to set authentication
3476 in IdPass style. It is enabled when three tokens are given - order
3477 is user, group and password.
3479 Fix memory leaks in MARC record handling for ZOOM.
3481 New option for YAZ client, -k <kilobytes> that sets
3482 maximum record size. Similar to -k option for generic frontend
3483 server and yaz-ztest.
3485 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3487 Prefix query parser reports "fail" when bad attribute set is given.
3489 Fix in MARC decoder. Proximity logging. Fix for attribute set
3490 in scan handler for server. Patches by Shigeru Ishida.
3492 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3495 Configure option --with-openssl=<dir> now works when a directory is
3496 specified. Patch provided by Morten Bogeskov.
3498 New option for YAZ client, -u <auth>, that sets authentication.
3500 ZOOM fix: error information was sometimes "missing", since error
3501 was cleared/reset too when it shouldn't.
3503 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3505 --- 1.8.4 2002/01/04
3507 Scan for ZOOM API. New object ZOOM_scanset. New functions
3508 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3509 ZOOM_scanset_destroy.
3511 New ZOOM function, ZOOM_connection_last_event, that returns type
3512 of last event (such as "receive data", "send data", "apdu received",
3515 New ZOOM option, schema, that specifies schema for retrieval.
3517 New CCL feature. Qualifiers can be aliases for one or more
3518 other qualifiers (if more than one is given, OR is used).
3520 ZOOM uses named result sets if target supports it.
3522 Two new YAZ client commands: . (dot, which sources a script of YAZ
3523 client commands), and ! (to execute shell command.). Implemented
3526 Working on Debian packages.
3528 --- 1.8.3 2001/11/19
3530 YAZ client enables named result sets only if target supports it.
3532 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3534 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3535 with key="host" to get same result.
3537 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3538 Function Z3950_resultset_record(s) returns references to records
3539 "owned" by resultset. To become owner use Z3950_record_clone.
3541 Function z_ext_record handles Extended Services. Thanks to
3544 --- 1.8.2 2001/11/12
3546 CCL Parser fix: ignore token comma when dealing with and-lists.
3548 Documentation updates for COMSTACK.
3550 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3551 Changed prototype Z3950_records. For some functions, int parameters
3552 were changed to size_t.
3554 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3557 New MARC decode/display function, marc_display_exl, which properly rejects
3558 non-ISO2709 records. YAZ client uses it.
3560 --- 1.8.1 2001/10/29
3562 Fix bug: local attribute set wasn't set correctly in PQF strings.
3566 * Old Z39.50 codecs no longer supported.
3568 Added ZOOM C binding. See http://zoom.z3950.org/
3570 Renamed states for COMSTACKs to avoid confusion with events.
3572 Implemented cs_look and proper cs_rcvconnect.
3574 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3576 Configure detects POSIX threads on OpenBSD.
3578 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3579 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3581 When error is returned from present handler, non-surrogate diagnostic
3582 is returned in present response (and fetch handler is no longer called).
3584 * Minor adjustments to pquery parser (PQF). Token characters may be
3585 escaped by using backslash (C-style).
3587 PQF parser allows string attribute values to be specified. For @attr,
3588 non-numeric characters after the equal-sign are treated as strings
3589 (e.g. @attr 9=title).
3591 CCL trunction character may be defined (@truncation in file)
3593 * function zget_ExtendedServicesRequest sets waitAction to
3594 waitIfPossible (was wait).
3596 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3599 CCL operator names may be set in field definition files (CCL_bibset).
3600 See ccl/bib1 for an example.
3602 Fixes in ASN.1 compiler for C++ compatibility.
3604 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3605 and "op_or" to avoid conflict with C++.
3607 Fixed problem with GNU readline detection on Redhat 7.0.
3609 Added step-size for Scan backend handler.
3611 Fixed bug that made the frontend server crash when no attribute
3612 set was specified for scan.
3614 Front-end server automatically switches to original working directory
3615 when installed as an NT service. Previously -w had to be specified to
3618 Added extended attributes for retrieval module (data1), so that data1
3619 records carry d1_readXML/SGML attributes. d1_read also supports
3620 null-data rules ( <tag/>)
3622 On UNIX when POSIX threads are available, a separate library libyazthread
3623 is created. Programmers should link with that library and the yaz library
3624 when using threads. The reason for the split was that some applications
3625 on Linux, such as Apache, doesn't work well when using shared objects that
3628 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3629 (or any frontend server) in SSL mode by specifying ssl: followed by
3630 address. Only tested on UNIX.
3632 Added feature for CCL module. Virtual structure s=al or s=ol generates
3633 and-list and or-list respectively instead of phrase search.
3637 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3638 log_mask_str. This was done to avoid name conflicts with other libraries
3639 (such as other PHP extensions).
3641 Added raw OID member for preferred record syntax (request_format_raw)
3642 and returned record syntax (output_format_raw) for backend fetch method.
3644 Config file yaz-config now accepts options so that it returns specific
3645 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3647 Shared library support for UNIX using GNU libtool.
3649 * Modified backend interface. Request/Response struct's replaced by
3650 one read/write C struct. For example bend_fetchrequest and
3651 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3652 Every handler - even search has to be registered in bend_init
3653 handler. This means that the YAZ library no longer refers to
3654 external functions and it makes it possible to make the whole
3655 thing a single DLL/SO.
3657 Added Segment handler for backend server.
3659 Added Zmbol/Zebra administrative functions to YAZ client.
3661 Threaded frontend server on UNIX (when POSIX Threads are available).
3662 Starting the server with option -T enables multi-threading.
3666 Added configure option --enable-comp/disable-comp to control use
3667 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3668 located in sub directory asn.
3670 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3671 in ${exec_prefix}/bin along with the other programs yaz-client and
3674 GNU automake used to maintain makefiles.
3676 Added several OID's.
3678 Changed retrieval module so that we can load records with no abstract
3679 syntax defined. Tagpaths in these records are fully composed of string
3682 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3686 On UNIX, the generated makefile now supports a proper 'make install'.
3687 The prefix can be set via GNU configure to set the install location
3688 (default is /usr/local).
3690 * YAZ programs client and ztest were renamed to yaz-client and
3691 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3692 locations, such as /usr/bin,/usr/local/bin,etc.
3694 * YAZ Header files were moved from include to include/yaz. YAZ Header
3695 files are referred to as include <yaz/log.h> rather than <log.h>.
3696 The YAZ include path (-I ..) is therefore the same as before. Programmers
3697 should update their #include statements or use -Ipath/include/yaz
3698 instead. The main motivation for doing this change is that YAZ header files
3699 can be installed in "standard" locations /usr/include,/usr/local/include
3700 without introducing conflicts, since ALL YAZ header files are stored
3701 in subdirectory yaz (under /usr/include for example).
3703 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3704 rather than project/workspace files. We switched because project files
3705 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3708 Changed name of logging function, logf, to yaz_log, to prevent name
3709 clash with some math-log functions. The YAZ header log.h defines logf
3710 to yaz_log (#define) so there should be no incompatibilities by this
3713 Added bend_start/bend_stop handlers for server. These handler are
3714 called on start/stop of server. For windows they are called whenever
3715 a service is started/stopped.
3717 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3718 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3719 in util/yc.tcl. The auto-generated C code structures are, in a few
3720 cases, incompatible with the old decoders. There are differences in the
3721 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3722 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3723 The preprocessor variable ASN_COMPILED is defined when the compiled
3724 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3725 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3726 wish to use the old encoders/decoders you can specify --disable-yc
3729 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3730 version so that it supports both new - and old version of DB Update
3732 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3733 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3734 change. The name parameter can be set to 0 in which no name is specified
3735 for the construction. The macros odr_implicit and odr_explicit sets name
3736 parameter to zero for the construction involved. New macros
3737 odr_implicit_tag and odr_explicit_tag are similar to the others,
3738 except that a name parameter is added. For programmers' that don't use
3739 ODR they probably only need to change the call to z_APDU and z_External.
3741 Added access control facility by interfacing the TCP wrapper library.
3742 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3743 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3744 name of the daemon and enables the access control as specified in
3745 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3747 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3748 den Dool <H.M.vdnDool@kub.nl>.
3750 Added reference ID parameter to most functions in server API - refer
3751 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3753 Changed name of ccl library to libccl.a (was ccl.a).
3755 Fixed bug in decoder for Explain (Category TargetInfo).
3757 Added support for GNU readline in client. Thanks to Jacob Poulsen
3758 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3760 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3761 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3762 IMPLEMENTATION! This change was made to the development version before
3763 the ZIG decided to retract the amendment. If any users MUST be
3764 compatible with the original Update definition, PLEASE CONTACT US, and
3765 we will include a separate definition corresponding to the old Update
3766 ES. Note that because of the change to the ASN.1 of the
3767 TaskPackageRecordStructure we cannot define a single structure that
3768 will support both versions.
3770 * Added const modifier to buffer parameter for some ODR/BER encoding
3771 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3772 completeWAIS, odr_dumpBER.
3774 Fixed bug in client.c which caused a crash when a scanResponse didn't
3775 contain positionOfTerm.
3777 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3778 * will cause an error in a client if a non-YAZ target sends both a
3779 * list of Scan entries and non-surrogate diagnostics.
3781 Retrieval module enhancements. Tag sets may be typed in the reference
3782 to it. From the .abs-file the "tagset" directive takes a third optional
3783 integer type for the tag set referenced. From a .tag-file the "include"
3784 directive takes a third optional type as well. The old "type" directive
3785 in the tag set itself is still recognized but acts as the default type
3788 Backend interface change. Individual Scan terms returned from bend_scan
3789 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3790 in include/backend.h.
3792 Retrieval module enhancements. Multiple tag sets and attribute sets may
3793 be specified in abstract syntax specs. Revised the error/warning for
3794 logging messages reported by the retrieval module when reading the
3797 Object Identifier system (oid_..) changed. The API is backwards
3798 compatible but the oid-routines now allocates new OID's when needed.
3799 Raw OID's may be specified in oid_getvalbyname.
3801 YAZ now uses GNU configure to generate Makefile(s).
3803 * Minor changes in some of the member names of DeleteResultSetRequest and
3804 DeleteResultSetResponse. See include/proto.h.
3806 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3807 and added member 'languages' in TargetInfo (which was missing).
3809 Changed the way attribute sets are handled in the retrieval
3810 module. These are now cached, just like the abstract syntaxes
3813 Changed YAZ so that it links with compiled ASN.1.
3815 Added Explain-schema definitions and mapping routines. The following
3816 Explain categories have been implemented: AttributeDetails,
3817 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3819 Fixed minor bug in Windows version of Server Library.
3821 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3823 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3825 Added EXTERNAL: UNIverse Resource Report (non-standard).
3827 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3828 ENUMERATED and SET OF.
3830 * Added 'const' to some of the char pointer arguments for the
3831 functions, data1_read_node, data1_getelementbytagname,
3832 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3835 Fixed bug in data1_insert_taggeddata - the last_child member of
3836 parent wasn't initialised.
3838 * Changed data1_read_record and data1_read_node so that the supplied
3839 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3840 doesn't refer to any parts of the "SGML"-buffer.
3842 Fixed bug in server library (Windows version of statserv_remove).
3844 * Changed code so that it compiles as C++. The type definition
3845 of Odr_fun which is a member of Odr_arm was changed. The result is,
3846 that an explicit typecast is needed for the fun pointer when
3847 using Odr_arm - as in:
3848 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3850 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3852 Implemented the new structured date and time definition as approved
3853 by the ZIG. Added schemaId element to the specificTag in Espec-1
3854 (also approved at the last ZIG). Thanks to RVDM.
3856 Added some Object identifiers (RVDM).
3858 Changed the Update Extended Service (RVDM).
3860 Added command "refid" to client which specifies referenceId for
3861 the following requests.
3863 Implemented extended service handling for server. See ztest.c
3864 for an example as well as backend.h. New handlers are registerd
3865 in the Init handler.
3867 * Changed interface for sort in server.
3869 Added new members to statserv_options_block. It allows a server
3870 to read options from another source than just the command line. Thanks
3871 to Charles Woodfield.
3873 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3874 renamed to zboolean. Some C++ compilers complained about the name.
3876 Minor changes to gils.abs. Added index 's' (sort) on title
3877 and date/time-last-modified.
3879 --- 1.4pl2 1998/1/30
3881 Fixed bug in server library regarding inetd mode (-i). This bug
3882 was introduced by release 1.4.
3884 --- 1.4pl1 1998/1/29
3886 Added sort facility in client and backend server interface.
3888 Fixed problem with dependencies in Makefile(s).
3890 Fixed bugs for encoders/decoders of extended services and
3893 Implemented sub-tree feature for schemas. Sub-trees are
3894 referenced in *.abs-files. See explain.abs for an example
3895 of the use of this feature.
3897 Modified bib1.att; local attributes for ANY didn't include
3898 ANY itself (only affects use of the retrieval module).
3900 Fixed bug in plain SGML reader in function data1_read_node:
3901 tags with prefix "var" was incorrectly interpreted as variants.
3903 Added feature "sub-schemas" to enable references to - and definitions
3904 of - group of elements.
3906 * Removed member parent from type data1_element (in data1.h).
3908 Implemented function odr_nullval() that returns the value of
3911 * Removed member num_children from data1_node (in data1.h).
3913 Made NT service interface part of the server library. The
3914 function statserv_main uses the NT service when required and
3915 calls the statserv_start / statserv_close routines.
3917 Routine zget_SearchRequest and zget_PresentRequest fills
3918 resultSetName/Id member with "default" instead of "Default".
3920 Fixed memory leak in server. Request queue member wasn't freed.
3922 Fixed nmem_exit so that memory is freed.
3926 Revised the CCL parser utility to be thread safe.
3928 Added function, oid_ent_to_oid, to replace the function
3929 oid_getoidbyent, which is not thread safe.
3931 * Added nmem_init and nmem_exit to initialize and release
3932 NMEM resources. Function nmem_init should be called once in the
3933 initial thread before NMEM/ODR is used. statserv.c and client.c
3934 have been changed accordingly. The change was necessary to make
3935 NMEM thread safe. The NMEM memory pool is shared amongst threads
3936 in a process. Unix-based applications will still work fine without
3939 Added NT Services interface for the the Z39.50 (statserv) Server.
3940 Refer to the ztest.c source on the usage.
3942 Windows 95/NT port using MSVC5.0. Project files are included in the
3945 * Defined new 'global' handle for the retrieval (data1) system. The
3946 new handled, data1_handle, describes the state of the data1 system.
3947 This handle is passed as first argument to virtually all
3948 data1 related routines. The functions data1_create and data1_destroy
3949 creates and destroys a data1 handle respectively.
3951 Added ODR encode stream member to all backend request structures
3952 init, search, scan etc. This stream should be used to allocate all
3953 memory used for the response when thread safe operation is needed.
3955 Changed the comstack utility, cs_addstr, to be thread safe. The
3956 returned hostname string returned by the function is now part the
3959 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3960 function. The cs_straddr takes a COMSTACK handle as argument, so this
3961 function must be used after cs_create and before bind/connect.
3962 This function is thread safe.
3964 Moved test server to 'ztest' directory - generic server code still
3965 in 'server' directory.
3967 Made prefix query (pquery.c) utility thread safe.
3969 Added new function modifier YAZ_EXPORT to 'export' public DLL
3970 functions when using windows (see include/yconfig.h).
3972 Added definitions to the OID database (util/oid.c) (RVDM).
3974 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3976 Added call to ccl_rpn_delete in client program.
3978 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3979 release of RPN structure.
3981 Added support for C++, headers uses extern "C" for public definitions.
3982 With input from RVDM.
3984 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3985 Thanks to Ronald van der Meer (RVDM).
3987 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3989 Added support for private extensions to the OID database
3990 (oid_setprivateoids()). Thanks to RVDM.
3992 Added optional, physical ANY (key replication)
3994 Fixed null-reference problem in GRS-1 output filter.
3996 Proximity operator added to Prefix Query Format (PQF).
3998 In test client command "base" accepts multiple databases.
4000 Fixed bug in cs_close stack that caused trouble with WINSOCK.
4004 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4006 Smallish bug-fixes in the new encoders/decoders (explain).
4008 Bug fixed in DeleteRequest.
4010 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
4012 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4014 Added SOIF syntax (using private OID for now) to retrieval module and client.
4016 Added Update extended service.
4018 Added SearchResult-1 additional info structure.
4020 Added optional CCL (ISO8777) interpreter as separate module. Available
4023 --- 1.2 1996/6/10 (1st anniversary release)
4025 Added Summary record syntax. Lightly tested.
4027 Added OPAC record syntax. Untested.
4029 Added ResourceReport service encoders/decoders. Untested.
4031 Fixed bug in z_Unit - wrong tagging on unitSystem.
4033 Fixed bug in the DiagRecs decoder.
4035 Added options for max PDU size and session timeout to frontend-server.
4037 Added documentation of query-language parsers and other supporting utilities.
4039 [frontend-server] Added Attribute set to the bend_scanrequest API.
4041 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
4042 surrogate diagnostics were generated.
4044 [retrieval] Allow multiple local values for attribute.
4046 [retrieval] Allow multiple attributes per element in .abs files. index type.
4048 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
4050 --- 1.1pl2 1996/4/10
4052 Minor changes, mostly specific to Zebra's requirements (retrieval)
4056 Repaired bug in frontend server when running multiple listening
4057 endpoints in dynamic mode.
4059 z_External() now won't break if a known, ASN.1 value comes encapsulated
4060 in an octet-string. The value will pass through unmodified in an Odr_oct.
4062 Added a bit of code to the demo client to decode & display
4063 ASN.1-structured records represented in the octet-aligned branch of
4064 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
4066 Added z_ext_getentbyref() to the ASN module. Doc updated.
4068 * Completed the SCAN definition in the ASN module. This may break SCAN
4069 code based on older YAZ-versions at compile-time. The fix is easy -
4072 * Added 'displayTerm' and OtherInformation to the TermInfo structure
4073 under the SCAN definition. Remember to initialize this, server-people.
4075 Comstack should now support the WAIS protocol in TCP/IP mode. Note
4076 that this does not extend to ODR and ASN.
4078 Comstack allows insertion of established socket (primarily for
4079 inetd-operation of servers). Doc updated.
4081 Front-end server can now start from the inetd in TCP mode. Doc
4084 --- 1.0pl4 1996/1/24
4088 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
4089 the rank and record number.
4091 Adjustments to the frontend server.
4093 Fixed diagnostic BER dumper. It ignored the file argument.
4097 Various changes to retrieval module.
4099 Changed the union discriminators of the protocol files from enums to
4100 ints paired with #defines.
4102 *Changed oident.class to oident.oclass to avoid a reserved word in C++
4105 *Changed operator in the RPN structure to 'roperator', again to avoid a
4108 Fixed problems in Explain decoders/encoders.
4110 --- 1.0pl2 1995/12/6
4112 Memory bug in log module fixed.
4114 --- 1.0pl1 1995/12/5
4116 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4118 Bug in Explain DatabaseInfo module fixed.
4120 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4124 The shift to v1.0 signals that we now consider the *core* functionality
4125 of YAZ reasonably stable (the core being more or less equivalent to
4126 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4127 tested (Explain not at all - though that will happen soonish).
4129 Minor changes to code to support Windows port.
4131 Various minor changes after we're getting to use GRS-1 & co. more.
4133 Added Espec-1 format.
4135 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4136 of the protocol and it cannot be selected when encoding (maps into 'string'
4137 when decoding). Needed to talk to some servers.
4139 Demo client can request simple element set names.
4141 Added Diagnostic Format encoders/decoders.
4143 Added simple Close handling to frontend server (no hooks for resource
4144 reporting yet), and demonstration client.
4146 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4148 --- 1.0b3 1995/08/24
4150 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4151 handled incorrectly when records were requested in the searchResponse. This
4152 will only affect you if you use the frontend-server.
4154 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4155 Test-client will ask for and print GRS1. Ztest will return dummy records
4158 Added Explain encoders/decoders to the service-level API. Untested.
4160 Added Extended Services: Item Order encoders and decoders to the Service-
4161 level API. Untested. We could use a recent copy of the pertinent bits
4162 of the ILL protocol to add those bits.
4164 Added diagnostic format 1 encoders/decoders to the service-level API.
4167 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4168 odr_cons.c, which causes a more correct output.
4170 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4171 was always set to 0 when no records were requested in the searchRequest.
4173 * Added better external-handling. This shouldn't harm old code that
4174 *encodes* externals. It can break code that looks for a
4175 'single-ASN1-type' representation, since those types that are known
4176 are now decoded immediately. Look at the SUTRS sample code in
4177 seshigh.c and client.c. Documentation updated.
4179 Handling of structured records in bend_fetchresponse. Length -1 marks
4180 structured record, type is deduced from format field.
4182 --- 1.0b2 1995/06/27
4183 Fairly quick maintenance release to add SUTRS support.
4185 Fixed handling of SUTRS records in the demonstration client.
4187 * Added format field to the bend_fetchrequest and bend_fetchresponce
4188 structures of the backend API (frontend server). When the record is
4189 returned, the value of the format field is mapped to an OID. The
4190 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4191 of the record. The special value VAL_NONE in the bend_request means
4192 that no specific format was requested by the client. Documentation
4193 updated accordingly. Test server (ztest) will return a fixed dummy
4194 SUTRS record if your client requests SUTRS.
4196 Documentation updated accordingly.
4198 You can now set external libraries and RANLIB support in the top-level
4202 First public release.
