3 No [rest of output is omitted] limit for yaz_log YAZ-774
5 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
7 For ICU testing, pass -o to yaz-icu. This will test the
8 icu_iter_get_org_info function.
10 Fix null ptr reference for freeReplyObject YAZ-773
14 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
16 RPM: do not build with libmemcached support. The libmemcached library
17 on CentOS 5/6 does not work reliably for us (redis to the rescue).
19 configure: only allow libmemcached version 0.40 or later. That's the version
20 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
21 that's not an option, consider redis.
25 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
27 Fix zoom+memcached: present request out of range YAZ-767
31 CCL: add new qualifier r=omiteq which will omit relation=equals
32 for ordered relations. This should be used in combination with either
35 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
37 Solr: simplify yaz_solr_decode_response
39 Solr: use different local var for string manipulation
41 Solr: Get rid of hardcoded limit of extra_args
43 Solr: encode lucene query type YAZ-736
44 Make sure the queries are treated as traditional "lucene", because that's
47 Fix ZOOM HTTP redirect failing on Windows+Solaris YAZ-755
51 Build packages for Ubuntu Trusty Tahr 14.04 LTS
53 wrbuf_cstr: fix off by one error.
55 wrbuf_buf: make it always return non-NULL
56 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
60 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
62 zoomsh: offer option -a apdulog
63 As we're used to from yaz-client and GFS based servers.
65 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
66 existing setting apdulog takes effect.
68 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
73 Add re-entrant CQL/Solr/RPN query conversion functions.
74 The re-entrant functions are: cql_transform_r,
75 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
76 These have same functionality as cql_transform,
77 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
78 return the additional infomration as WRBUF to make them re-entrant.
80 Remove CQL to Solr conversion and base solr_transform_t on
81 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
82 data structure as cql_transform_t.
84 cql2pqf utility allows RPN to Solr conversion
86 Fix assert in ZOOM when http connect fails YAZ-757
90 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
92 wrbuf_cstr: make it thread safe YAZ-753
94 yaz_log_init_file may take fd=<no> to open log file at the FD given.
98 Offer new utility function zget_AttributeList_use_string.
100 New conversion step, solrmarc, for record conversion module.
102 --- 5.0.20 2014/03/13
104 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
105 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
108 --- 5.0.19 2014/03/10
110 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
111 The standalone ZOOM sort was completely broken since 5.0.13.
113 ZOOM: generate event Connect rather than None for partial connect
114 (in fact getaddrinfo resolving).
116 ZOOM: only supply clientIP for InitRequest. Rather than for all
119 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
121 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
122 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
123 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
125 New "Facets" section in the documentation.
127 --- 5.0.18 2014/02/27
129 Call exsltRegisterAll in yaz_init_globals, so that all applications
130 using YAZ will have EXSLT things enabled.
132 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
134 Update various URLs to the re-organized SRU pages at LoC.
136 --- 5.0.17 2014/02/26
138 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
139 introduced in 5.0.12.
141 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
142 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
143 Do not call yaz_init_globals from log_mask_str_x. Problem introduce

152 Fix gcrypt not properly initialized YAZ-740.
154 --- 5.0.14 2014/02/19
156 Describe memcached option for ZOOM.
158 ZOOM: throw present request out of range again YAZ-739
159 Was removed in YAZ 5.0.13.
161 --- 5.0.13 2014/02/18
163 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
164 with localtime_r when threads + fork is used (such as Metaproxy).
166 yaz-config: quote some RHS values (that might include blanks)
168 zoomsh: shows SearchResult-1
170 zoomsh: sortby command
172 zoomsh: use proper list of connections and result sets YAZ-725
174 Avoid yaz_log in sigterm handler for GFS YAZ-737
175 Logging is still performed, but outside sig handler.
177 New ZOOM C feature: result-set caching with memcached. Example:
178 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
180 Remove SSL via OpenSSL support YAZ-732
181 Also deprecate two functions from comstack that aren't working with
182 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
184 Revert "Bison: use %name-prefix directive rather than -p option"
186 --- 5.0.12 2014/01/22
188 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
190 SRU GET/Solr base URLs may hold additional ?args YAZ-729
191 ZOOM option extraArgs already does this, though. It seems useful
192 when dealing with Solr targets to limit by filter, eg.
193 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
195 Remove #fragment for HTTP request encoding YAZ-730
197 Doc: Update list of DLLs/LIBs
199 Doc: update href link to Unix utils and Git.
201 --- 5.0.11 2014/01/15
203 ZOOM: fix "lost connection" problem with servers that uses both squid
204 and another proxy behind it that returns Location headers with relative
207 zoomsh: do not use readline for stdin (no tty) YAZ-724
208 Just use fgets in that case. If the user hits Ctrl-D a new-line
211 zoomsh: empty command ignored YAZ-723
212 rather than performing exit of zoomsh.
214 yaz-url utility offers option -v to enable verbose mode.
216 yaz_url uses yaz_check_location and offers verbose mode.
218 Add new function yaz_check_location.
219 This function gets an absolute URI from Location (HTTP redirect).
221 cookie API: introduce yaz_cookies_reset
223 Update cql.y for newer bison YAZ-720
224 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
225 longer supported. Instead one must use %lex-param and %parse-param .
227 --- 5.0.10 2014/01/09
229 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
232 rpn2solr: support truncation left(2), left&right(3) YAZ-718
234 Mention SRU version 2.0 in yaz-client man page.
238 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
243 Make cs_parse_host public.A
245 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
246 introduced in YAZ 5.0.6.
250 Fix buffer corruption for yaz-ztest record fetch.
254 Allow yaz-ztest to return user-defined records (one record per file).
255 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
257 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
258 Use the stream write instead of odr_printf which has a 4K tmp buffer.
260 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
264 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
265 can read and write this format. For record format JSON, yaz-ztest returns
266 MARC-in-JSON records.
268 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
269 converted to @å , 0xa732 is converted to @Å instead of @a733, @a732 .
273 Improve error reporting for ICU chains YAZ-707
274 Report config element+rule when ICU status is "failure".
276 ZOOM: stop fetching if present response has no records YAZ-710
277 Some targets return less records than their hit count would suggest.
278 This prevents ZOOM from continuing to fetch records if any present
279 response has 0 records in the response.
281 Ensure that GFS calls exit if any listener fails YAZ-710
282 Before, if XML config was in use, it would start the default
287 yaz-ztest: -V shows version (like yaz-client -V)
289 New iconv encoding: danmarc YAZ-692
291 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
293 daemon: only wait for immediate child rather than all children. YAZ-704
295 yaz-client: fix setting of SRU record schema. If scheme was unset, it
296 could lead to invalid memory reference.
300 yaz-ztest returns schema for MARCXML test records. SRU require that
301 recordSchema for records.
303 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
304 instead of non-surrogate diagnostic. This is a per-record failure.
306 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
307 may refer to multiple listeners now. Attribute listenref is a comma separated
310 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
311 option is given for GFS, the dirname of filename (for -f) is used
312 as prefix for options such as cql2rpn, ccl2rpn, etc.
314 Content-Type charset fixes YAZ-701 . Do not inspect charset in
315 Content-Type header for SOAP when decoding SRU. The payload (XML)
316 itself tells what encoding it is. In response, never supply encoding
317 in Content-Type. The response payload (XML) tells what it is (with no
318 encoding in XML it's UTF-8).
320 HTTP decoding: allow blanks in URL paths YAZ-700
324 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
325 and facets. Ensure recordData and recordSchema are always present in
326 record element, because they are required.
328 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
331 Simplify in a lot of places using odr_strdupn.
333 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
337 Increase various buffers in GFS's statserv_options_block
338 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
339 This change makes many type-casts redundant, and, thus simplifies code.
341 Remove last bits of WAIS support.
343 Remove member 'size' from Odr_oct.
345 Slim down the public part of 'struct odr'. Most elements are not part
346 of struct Odr_private.
348 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
349 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
350 In particular facets are supported in both client - and server side.
351 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
352 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
353 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
354 both request/response). This is what a search handler in the GFS
355 will see (regardless of whether operating in SRU mode or Z39.50).
357 Changes to the srw.h (SRU/Solr) definitions include:
358 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
359 (char*), which replace union query and query_type (int). This is because
360 SRU 2.0 supports a queryType parameter. This also means that, to carry
361 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
362 x-pquery=PQFstring (extention parameter). The extension parameter
364 - New element, packing, that has information about SRU
365 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
367 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
369 New element, packing, in Z_SRW_explainRequest.
371 New elements in Z_SRW_scanRequest, queryType and scanClause.
372 These replace query_type and scanClase untion. This is similar to what
375 --- 4.2.69 2013/10/01
377 GFS: log when closing down - at least SIGTERM YAZ-684
378 Also change formatting WRT PID logging a bit.
380 Improve display of MARC records with multi-byte subfield IDs YAZ-695
381 In some rare cases subfield identifiers are multi-byte characters.
382 This will try to deterime length of those and split accordingly.
383 This affects display in line mode as MARCXML/MarcXchange. The encoding
384 of ISO2709 is the same.
386 Change inp argument to const for yaz_read_UTF8_char.
388 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
390 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
392 Better check of marc leader info YAZ-691
393 Problem is that some systems generate MARCXML/MarcXchange with
394 funny headers. These will not work if encoded as ISO2709.
395 Some tests produce new output, due to updated warning messages
397 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
399 yaz-client: display MAB records YAZ-689.
400 Thanks for Heiko Jansen for this patch.
402 New utility z_get_HTTP_Response_server which allows both HTTP server name
403 and HTTP server URL to be given in response.
405 Debian: do not depend on obs tcl8.3.
407 Debian: do not depend on obs libicu36-dev.
409 --- 4.2.68 2013/09/23
411 GFS: pass additionalSearchInfo to search memeber search_input if
412 given. Otherwise pass otherInfo. Request for facets and other search
413 related things will be passed there in future versions of YAZ.
415 New ZOOM setting, authenticationMode, which allows authentication
416 paramters to be encoded in the URL rather than via HTTP Basic auth.
419 rpn2solr: fix nested AND/OR handling. YAZ-685
421 Add comparison routines for some Z-types, such as NamePlusRecord,
422 RPNQuery, Query, RecordComposition and OtherInformation.
424 --- 4.2.67 2013/09/19
426 Don't decode MAB as MARC. Just like we don't attempt to decode
427 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
429 CCL: allow quoted terms for date ranges. YAZ-681
431 Introduce ccl_parser_qual_search. This function makes old function
432 ccl_qual_search, from YAZ 2, available again.
434 Add yaz_facet_list_to_wrbuf. YAZ-683
436 --- 4.2.66 2013/09/11
438 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
439 schema was given for search. YAZ-675
441 Add Solr date range searches. YAZ-621
443 --- 4.2.65 2013/08/22
445 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
447 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
449 ISO2709/MARC parse most octet aligned records; not just those that
450 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
451 MARC parse more records instead of just dumping as is. YAZ-670
453 ZOOM: proper caching for variations of record schema. YAZ-671
455 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
457 --- 4.2.63 2013/07/17
461 --- 4.2.62 2013/07/11
463 New utility z_get_HTTP_Response_details - an extended version of
466 New utility yaz_url_get_error which returns error message of last
467 failed yaz_url_exec call.
469 yaz-url and url functions: allow max HTTP redirects to be controlled.
471 New functions yaz_file_glob2, yaz_xml_include_glob.
472 These functions takes a flags parameter, which, for now only controls
473 whether to fail inclusion of a non-existing file (without glob
474 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
476 --- 4.2.61 2013/06/20
478 For MARC XML parsing, allow record without leader. A fake/default leader
479 is inserted and a warning is tagged with the record.
481 ICU: fix leak in in icu_iter_get_org_info.
483 --- 4.2.60 2013/06/14
485 ICU: fix bug in icu_iter_get_org_info (un-init variable).
487 --- 4.2.59 2013/06/11
489 Implement z_HTTP_header_remove.
491 --- 4.2.58 2013/06/11
493 ICU: Disallow 0 ptrs for some ICU string utilities.
495 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
496 returns original tokens (before normalization).
498 CCL: avoid z39.58/regex truncation when not needed. Apply only the
499 conversion of those masks, when absolutely necessary.
501 CCL: configurable masking character - @mask. Default masking character
504 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
505 full response anyway, so a Transfer-Encoding header will obstruct the
508 --- 4.2.57 2013/05/15
510 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
511 picking a socket. Problem is that some systems has IPV6 support, but
512 we can't create sockets for them, so we pick AF_UNSPEC first.
514 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
515 use content_len to determine resulting Content-Length in HTTP response
516 and NOT Content-Length supplied in headers by user.
518 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
519 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
521 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
524 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
525 with big endian and unsigned char (by default).
527 --- 4.2.56 2013/04/26
529 Fix yaz-client connect (crash in 4.2.55).
531 --- 4.2.55 2013/04/26
533 Fix proxy/host problem for ZOOM that could occur if unix sockets
536 New Debian package libyaz4-dbg.
538 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
539 differently in tcpip_close.
541 --- 4.2.54 2013/04/17
543 Windows installer of YAZ includes YAZ4J as a component.
545 CQL: allow "extra terms" again, by default. Thus, the CQL parser
546 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
547 and earlier. CQL parser may operate in strict mode where queries
548 not conforming to the standard BNF are rejected (syntax error).
549 Whether the CQL parser operates in strict mode is controlled with
550 cql_parser_strict . Strict mode enabled with option -S for utilities
551 cql2pqf and cql2xcql .
553 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
555 --- 4.2.53 2013/04/10
557 New charset, MARC-8c, which is like MARC-8 but allows control characters
558 0x01 through 0x1F, except ESC to be passed through verbatim.
560 Fix a problem with duplicate sub field character in MARC output. Problem
561 happened only when output was MARC-8 encoded.
563 --- 4.2.52 2013/04/03
565 yaz-ztest: Use hash for fake hit count. Before, random number was used.
566 This is problematic for unit tests using yaz-ztest. This patch also makes
567 a hash for CQL queries. For RPN, any term with a leading digit will be
568 treated as pseudu hit count (to force any particular hit count by a client).
570 yaz-ztest: return unique MARC dummy records. Beyond record offset
571 24, the author surname is patched with offset to make all records
574 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
575 on system wide default (/proc/sys/net/ipv6/bindv6only).
576 @4 binds to IPV4 only. @6 binds to IPV6 only.
578 Update CQL API documentation a bit
580 CQL: don't accept extra terms for queries. Makes the CQL parser
581 stricly conformant to the standard.
583 --- 4.2.51 2013/02/12
585 GFS: scan handler gets extra_args from request and may return extra
586 response data . That's for SRU only.
588 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
590 --- 4.2.50 2013/01/30
592 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
594 OPACXML: sync spelling of availabilityDate in XML to that of Schema
595 opaxxml.xsd. The schema had the correct spelling of this member always.
596 The ASN.1 was mis-spelled and still is (API change) - we are
597 not changing this. However, the OPAC to XML conversion had yet
600 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
603 New function, z_ext_record_oid_nmem, which is similar to
604 z_ext_record_oid but takes NMEM rather than ODR
606 --- 4.2.49 2013/01/18
608 ICU: New conversion element 'join' which joins tokens into one
609 with a custom character given by rule attribute.
611 --- 4.2.48 2013/01/10
613 New GFS search member: present_number. This is a hint to the
614 search handler how many records are going to be fetched immediately
615 following search. There's no guarantee that it's going to be the case,
616 since it depends on hit count (for Z39.50 piggyback) and whether errors
619 Make a few functions static (private). The functions getbyte_stream,
620 ungetbyte_stream and yaz_gets are now private. They were never declared
623 yaz-marcdump: exit(5) for serious decoding errors
625 ISO2709 decoding: be more picky WRT header
627 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
628 was only used as to indicate that next-result-set-position should be
630 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
631 Based on patch from Ashley Sanders.
633 Make some functions static/private in PQF parsing. Those functions were
634 never declared in a public header and so should not be in use by
635 applications based on YAZ.
637 --- 4.2.47 2012/11/23
639 ZOOM: special options to control APDU logging.
640 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
641 logging of APDUs until "saveAPDU" option is set again. If logging is
642 already enabled the effect is that current APDU buffer is cleared.
643 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
644 logging (default behavior on new connection).
645 The APDUs sent/received can be obtained by using
646 Using ZOOM_connection_option_get(c, "APDU") or
647 ZOOM_connection_option_getl(c, "APDU", &l).
649 GFS: relay implementation_version from backend
650 From 3.0.40 and later, implementation_version from backend was
651 not used in init response at all.
653 --- 4.2.46 2012/11/15
655 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
656 mode at all. Probably never did.
658 Make a new version of ztest.pem that, at least, is not expired.
660 --- 4.2.45 2012/11/13
662 Fix description of CCL directive 'case'.
664 More tight checking of form arguments (yaz_uri_to_array). Makes
665 YAZ better at rejecting big and/or bad POSTs.
667 SRU decoding does not report more than up to 10 invalid arguments.
669 rpn2cql: less quotes in generated terms. Semantics unchanged, but
670 it's prettier this way.
672 --- 4.2.44 2012/10/25
674 New utility yaz_decode_init_diag. Defined in proto.h.
676 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
677 given for unix local socket.
678 The COMSTACK string for doing so is:
681 unix:/myfile:tcp:localhost:9999/mybase
682 unix:/myfile:localhost:9999/mybase
683 unix:/myfile:http://fakehost/mybase
685 debian: Use dpkg-buildflags in build process.
687 --- 4.2.43 2012/10/19
689 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
690 global's SRU service uses a recordPosition scheme starting from zero.
691 First record's position should be one
692 according to the standard.
694 --- 4.2.42 2012/10/18
696 Allow more namespaces for SRU. This is to allow, for example, an
697 incorrect namespace returned from server
698 http://services.igi-global.com/sru .
700 Minor fixes for compilation on Windows.
702 --- 4.2.41 2012/10/11
704 daemon: log total number of bad signals from child on stop so that it
705 is more easy to spot problems with child worker processes.
707 retrieval: empty backend name attribute omits element set
708 from being used in retrieval.
710 --- 4.2.40 2012/10/04
712 Implement Solr sort strategy "solr", similar to sru11 sorting.
713 This will implement the correct parameters on Solr requst to do
716 --- 4.2.39 2012/09/28
718 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
721 MARC: Extra/missing indicator handled for MARCXML.
722 The indicator length is given in header and is the same for the
723 whole record. If attributes ind1, ind2 are missing, then content
724 character defaults to blank. Extra indicator attributes (beyond)
725 indicator length are treated as an error.
727 Reformat: delete trailing whitespace
729 --- 4.2.38 2012/09/17
731 MARC: fix non-ASCII characters for leader. This is to ensure we can
732 generate XML in UTF-8.
734 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
735 in one node with structure word.
737 --- 4.2.37 2012/09/04
739 yaz-json-parse: JSON output may be pretty printed by using option
742 Increase default value of max message for Z39.50 Init for GFS, ZOOM
743 and yaz-client. Old value was 1 MB. New value is 64 MB.
745 --- 4.2.36 2012/08/22
747 yaz-client: don't display bogus records from SRU servers. Some SRU servers
748 return more records than given by *maximumRecords*. Skipping those in
751 record_render: simplify buffer return handling and fix at least one bad
752 memory reference, that broke the test_embed_record sometimes.
754 Allow http://user:pass@host notation for yaz_url_exec.
756 zoomsh: allow shell command to be executed. Via the system(3) call.
758 yaz_poll: Allow num_fds == 0
760 yaz-client: fix bad encoding of "itemorder item". The itemorder
761 item <no> - command forgot to use length of encoded Item Request
762 package. Error present since YAZ 3.
764 yaz-ztest: fix bad usage of session handle. Bug was introduced when
765 result sets were saved (271a9c83).
767 SRU recordPacking: guess record packing in response rather than looking
768 at the recordPacking element which, OF COURSE, changed semantics in SRU
771 Decode SRU 2.0 responses. The official namespace for responses, according
772 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
773 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
774 nature.com's server, however, usee namespace
775 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
776 we are now using a glob-expr to match up the namespace. ZOOM C and
777 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
778 I can not find a single real example showing the "real" namespace in
779 the documentation from OASIS. The namespace for requests is different
780 from responses, but this is not added to YAZ yet, when we don't encode
783 --- 4.2.35 2012/06/26
785 zoom/record_render: add support for Base64 decoding fo MARC records
786 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
787 which will decode base64 + ISO2709 marc-8 encoded material from text node
790 --- 4.2.34 2012/06/07
792 Add missing definitions ZOOM_resultset_get_facet_field_by_index
793 and ZOOM_resultset_facets_names.
795 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
798 Change APDU dump printing to avoid long leading blanks. For levels 16
799 or larger the level is shown and the indentation is truncated but
800 recursed with modula 8. This makes it still reasonable easy to read
801 - even for nested BER dumps.
803 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
804 return 0 (incomplete package) in case where the BER package was
805 considered too nested (return value of -2).
807 dumpber: lines of level 15 are not indented further. Two spaces per
808 indentation; indentation 15 or more is indented to a fixed indentation
809 and augmented with a level=<no> indication.
811 zoomsh: increase max size of command+args
813 GFS: No limit in RPN buf size in CQL to RPN conversion.
815 --- 4.2.33 2012/05/09
817 New function for daemon utility, yaz_daemon_stop .
819 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
821 --- 4.2.32 2012/04/25
823 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
824 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
826 --- 4.2.31 2012/04/23
828 YAZ daemon utility relays SIGUSR1 to child process.
830 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
831 would result in en empty database list - which in turn would result in
832 encoding failure for search.
834 Fix reading beyond string in yaz_sort_spec.
836 --- 4.2.30 2012/04/11
838 Add two new SRU diagnostics:
839 236: Access to specified database denied
840 1015: Init/AC: Maximum number of simultaneous sessions for Userid
842 Document the very useful ZOOM-C option "apdulog".
844 CQL to RPN: term may be passed through verbatim. This is enabled with
845 truncation.cql . The assumption being that the term is already CQL.
847 --- 4.2.29 2012/03/20
849 record_conv: leader spec may be given for marc element.
850 The leader spec is given as attribute leaderspec for element marc.
851 For example to convert a MARC21 record from MARC-8 to UTF-8:
852 <marc inputformat="marc" outputformat="marc"
853 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
855 record_conv: allow user-XSLT params. For example:
856 <xslt stylesheet="MARC21slim2DC.xsl">
857 <param name="myparameter" value="myvalue"/>
858 <param name="otherparameter" value="othervalue"/>
861 record_conv: fix error handling for missing marc charsets.
863 CQL: fix extra terms in wrong order.
865 --- 4.2.28 2012/03/06
867 record_conv: modify new API for conversion types. The conversion types
868 may be passed in new functions yaz_record_conv_configure_t and
869 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
871 Avoid mixed statement/variable declare; fixes compilation with Visual
874 --- 4.2.27 2012/02/28
876 Add non-standard SRU diagnostic: 235: "Database does not exist".
877 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
878 Update SRU to Bib-1 diagnostic maps accordingly.
880 CCL: add two new diagnostics for unsupported masking. The new
881 diagnostics are: "Embedded truncation not supported" and
882 "Single charcacter mask not supported".
884 --- 4.2.26 2012/02/23
886 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
888 --- 4.2.25 2012/01/11
890 Build YAZ for Ubuntu Oneiric.
892 CCL: allow parantheses for proximity operands. For example CCL query
893 (a) % (b) is now allowed.
895 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
896 marked dead, rather then being destroyed. If not, the session memory is
897 being free'd before the search/scan handler is finished. Also destroy
898 'request' memory in request_release rather than in various places,
899 which resulted in leaks from time to time.
901 --- 4.2.24 2011/12/21
903 cql_sortby_to_sortkeys: honor sort prefix.
905 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
906 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
907 The rpn2cql family of functions now always returns quoted CQL terms.
909 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
911 --- 4.2.23 2011/12/15
913 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
914 sequence is treated as one. For example, &&a=b&&&c& is identical to
917 --- 4.2.22 2011/12/05
919 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
920 APDUs for a connection to a WRBUF.
922 --- 4.2.21 2011/11/23
924 Fix cql_sortby_to_sortkeys. Completely broken before.
926 Make CCL's @truncation work again.
928 --- 4.2.20 2011/11/09
930 New ZOOM connection setting: tproxy. It's like proxy, but does not
931 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
932 to set resolved address + port for a connection outside ZOOM itself.
934 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
936 --- 4.2.19 2011/11/07
938 Fix uninitialized variable in Solr spell support (could cause SEGV
939 for SRU response decoding).
941 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
942 back-end's addinfo through into the ZOOM response addinfo.
944 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
945 they are separated by a colon and a space rather than simply
948 --- 4.2.18 2011/10/28
950 Add support for Solr spell-checking/suggestions through ZOOM.
951 If a Solr target has been configured correctly for spelling-checking
952 and suggestions, these will now be returned on the ResultSet option
953 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
955 --- 4.2.17 2011/09/28
957 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
958 with a flag whether to substitute escape sequences or not.
960 --- 4.2.16 2011/09/22
962 Fix nmem_strsplit_escape to substitute escape char properly.
964 New option for zoomsh -e , which makes it abort on first error and
965 return process exit code to indicate success/failure.
967 YAZ options utility supports special option -- which makes all it treat
968 all following arguments as non-options.
970 --- 4.2.15 2011/09/16
972 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
973 searched if absolute filename is given.
975 Fix conv_xslt() error-reporting when stylesheet is not found.
976 (The value of fullpath is meaningless in this situation.)
978 --- 4.2.14 2011/09/07
980 Fix problem in CQL sort node creation: un-initialized memory.
982 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
983 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
984 CQL sortby depending on whether Type-1 or CQL is actually sent to the
987 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
988 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
990 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
991 will make it possible to use both single-character mask (#) and wildcard (?)
992 in CCL . Throw diagnostic for left truncation because that is not supported
995 --- 4.2.13 2011/09/01
997 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
998 cases using escapes (\-sequences) and masking.
1000 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1001 would result in a read one byte beyond string.
1003 rpn2ccl may use Z39.50 masking for terms (t=z).
1005 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1007 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1008 not --cppflags (which seeems like an error in icu-config).
1010 --- 4.2.12 2011/08/27 RPM package only
1012 cql2ccl: fix conversion of terms: operator characters were not
1015 --- 4.2.11 2011/08/25 RPM package only
1017 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1018 CCL parser will map both # and ? to their regular expression
1019 quivalents (. and .*).
1021 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1022 of reserved CQL characters.
1024 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1025 is, so that they are passed through.
1027 --- 4.2.10 2011/08/24
1029 ZOOM SRU mode: more aggressive re-connect.
1031 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1032 made available as a utility function, declared in <yaz/logrpn.h>
1034 rpn2cql_structure() supports proximity nodes (except that the Type-1
1035 proximity node's "exclusion" binary is ignored, as there is no way to
1036 express that in CQL). Fixes bug #4564.
1038 --- 4.2.9 2011/08/18
1040 Fix SEGV that could occur if set command of zoomsh was given without
1041 value (2nd argument).
1043 Fix SEGV that could occur if unsupported transport was given for
1044 COMSTACK - say https (when SSL was unavailable).
1046 Build yaz-url on Windows too.
1048 --- 4.2.8 2011/08/11
1050 New utility to get web content. Header is url.h. A command line tool
1051 yaz-url is part of the distribution and packages.
1053 Fixes for SSL COMSTACK (when gnutls is in use).
1055 New functions yaz_base64{encode,decode}. Header is base64.h.
1057 --- 4.2.7 2011/08/03
1059 ZOOM C includes HTTP response buffer as additional info if it fails
1060 to decode the SRU response.
1062 Make wrbuf_json_puts available.
1064 --- 4.2.6 2011/07/28
1066 zoom: throw diagnostic for invalid value for option "sru". Before a
1067 bad SRU request was sent.
1069 Adding new utility wrbuf_vp_puts.
1071 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1073 --- 4.2.5 2011/07/21
1075 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1076 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1077 redirect was used at the same time.
1079 MARC line mode decoding: be less picky about length given - first
1080 5 digits of header that is.
1082 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1084 Changes to decoding of SRU records: a record with recordPacking=xml is
1085 modified with a new root element <yaz_record> if the recordData contains
1086 multiple children elements. This is to make the record XML parseable
1089 RPN to Solr conversion: encode special characters.
1091 Generic Frontend Server: fix uinitialized member, stepSize.
1093 --- 4.2.4 2011/06/21
1095 Fix a bug in SRU decoding of records.. The database records stored
1096 had un-initialized memory, but it would only be seen with yaz_record_render
1097 and type_spec="ext" .
1099 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1101 --- 4.2.3 2011/06/17
1103 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1105 --- 4.2.2 2011/06/10
1107 Add new utilities to convert from CQL to CCL . These utilities have
1108 prefix cql_to_ccl defined in cql.h.
1110 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1111 lead to memory heap corruptions when ICU utilities were in use.
1113 --- 4.2.1 2011/06/07
1115 Make compilation work without Libxml2.
1117 yaz-client: remove redundant blanks in display of searchResult-1 term
1120 --- 4.2.0 2011/05/18
1122 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1123 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1125 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1126 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1127 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1128 Note that the CQL sortby spec is only converted when the GFS is already
1129 converting from CQL to RPN (cql2rpn element).
1131 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1132 specify whether to collapse delimitors or not. The existing nmem_strsplit
1133 do collapse (collapse parameter = 1).
1135 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1137 Rename internal func yaz_use_attribute_create. While non-static, this
1138 function is not declared in a public header.
1140 --- 4.1.7 2011/03/15
1142 Add -lCrun when linking with ICU on Solaris.
1144 More quicks character set conversions for OPAC records.
1146 --- 4.1.6 2011/03/10
1148 fix problem with record_render: records were converted (character set
1149 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1151 --- 4.1.5 2011/03/08
1153 SRU: add methods for handling DADS SRU-proxy facets.
1155 Separate OPAC record character set for ZOOM_record. yaz_record_render
1156 allows a character set given as charset=from/opacfrom,to where 'from' is
1157 the character set of a bibliographic record, 'opacfrom' is character set
1158 of OPAC record and 'to' is the target character set.
1160 --- 4.1.4 2011/02/21
1162 yaz-client: show may XML format records. Command show followed by 'format'
1163 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1166 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1169 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1171 --- 4.1.3 2011/01/27
1172 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1174 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1175 this package can be distinguished from other vendors.
1177 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1178 as determined by configure
1180 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1182 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1183 returns no error and no record, the present request is considered
1184 partial (only a subset of the records could be returned by backend), and
1185 so it is appropriate to set Present Status to partial-4.
1187 --- 4.1.2 2010/11/02
1189 Move yaz-config man pages to section 1.
1191 More documentation about Solr.
1193 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1194 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1195 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1196 peers on some Linux systems. However, in general that does not work
1197 so YAZ can not rely on that to work. Debian changed behavior in this
1198 respect from Debian lenny to Debian squeeze (still testing as of Oct
1200 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1202 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1204 --- 4.1.1 2010/10/05
1206 Fix yaz-config output: echo_source not set correctly by configure.
1208 --- 4.1.0 2010/10/05
1210 Solr Web Service support for yaz-client and ZOOM.
1212 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1214 --- 4.0.12 2010/08/17
1216 Z39.50 facet support. Facet specifications are passed for search in
1217 other-information with ASN.1 as defined in facet.asn and OID
1218 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1219 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1220 3 is limit (number of entries to get in response). yaz-ztest returns
1221 dummy facets if a client asks for them.
1223 --- 4.0.11 2010/07/09
1225 CCL fixes: bug 2895 and bug 3539.
1227 GR1-display: add comma in display - was removed by mistake in
1230 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1232 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1234 --- 4.0.10 2010/06/18
1236 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1237 result set from a connection. The result set will be on its own
1238 thereafter; no operations on it will perform retrievals from a target.
1239 Only cached copies are returned.
1241 ZOOM C:fix case for HTTP servers responding with Connection:close.
1242 Ensure that if there is a current task it is resumed (like fetching
1243 more records in a result set) . Bug #3484.
1245 PQF parser: use odr_atoi for Odr_int (not atoi)
1247 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1248 values that contain any non-digits are treated as string attributes
1249 (previously decoding only checked for leading character ([0-9]). PQF
1250 encoding: attribute string values are not surrounded by double-quotes.
1252 --- 4.0.9 2010/05/21
1254 New utility for managing threads - thread_create.h.
1256 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1257 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1258 but YAZ' implementation do.
1260 Fixes for yaz_cond-functions on Windows 7.
1262 DLL export more symbols.
1264 zoomsh: show record do NOT render opac.
1266 Remove *.la files from Debian and RPM packages.
1268 --- 4.0.8 2010/05/11
1270 Debian package libyaz-dev depends on libgnutls-dev again (was
1271 removed in YAZ 4.0.6, but due to Libtool it is still needed
1272 even though yaz-config do not list libgnutls libs).
1274 ZOOM: Use only one WRBUF for returning string results for
1275 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1277 ZOOM: ZOOM_connection do not use a shared pointer to
1278 ZOOM_resultset after ZOOM_resultset is destructed by
1279 user. Reverts to YAZ 4.0.4 behavior.
1281 --- 4.0.7 2010/05/04
1283 record-conv: fix problem with at least one XSL conversion -
1284 due to probably incorrect usage of XML XSL documents.
1286 --- 4.0.6 2010/04/29
1288 Fix yaz-config for static mode and the use of SSL (gnutls).
1290 --- 4.0.5 2010/04/29
1292 Forward decl timeval struct in mutex.h and gettimeofday.h.
1294 yaz-config: fix 'static' mode linking.
1296 --- 4.0.4 2010/04/28
1298 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1299 are wrappers for pthreads or Windows. For Windows these are put in
1300 a separate DLL: yaz_cond4.
1302 libyaz.la (whole source) is compiled with thread. If thread support
1303 is enabled enabled, all source of YAZ is compiled with treading support.
1304 This allows core utilities such as yaz_log to use thread facilities.
1305 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1306 thread utilities. This commit moves mutex utilities (mutex.c) from
1307 libyaz_server.la to libyaz.la.
1309 yaz-json-parse displays leading text until error.
1311 --- 4.0.3 2010/04/09
1313 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1314 patch from Giannis Kosmas.
1316 SRU: no longer URL encode SRU database. The URL for an SRU server is
1317 a URL and such is alreeady encoded - at least when given with leading
1318 http:// or https://. This reverts behavior to YAZ 3.0.50.
1320 Support for new MARC XML notation TurboMARC which like MARCXML is a
1321 complete representation of MARC/ISO2709.. This one, however, is more
1322 compact and allows for faster processing with XSLT. TurboMARC can be
1323 used in the marcdisp.h API, from the yaz-marcdump utility and from
1326 yaz-ztest can be configured - via the database - to perform certain
1327 delays when it performs operations search, present and single record
1328 fetch. This allows testers to make yaz-ztest act as a real or even slow
1329 Z39.50 server. Refer to the yaz-ztest man pages for details.
1331 --- 4.0.2 2010/03/09
1333 wrbuf_destroy allows NULL WRBUF passed to it.
1335 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1337 Add ZOOM_connection_close.
1339 No fixed size buffers for ZOOM shell - bug #3257.
1341 tstodr: make it work on s390 platform.
1343 New icu iterator-functions. The new icu_iter-functions makes it possible
1344 to use ICU chains from many threads.
1346 yaz-client: better syntax check for show command.
1348 --- 4.0.1 2010/01/26
1350 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1353 New simple local-file XML include facility which allows file glob-patterns.
1354 Refer to yaz/xml_include.h.
1356 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1359 ZOOM_record_get supports new parameter "format" which makes it format XML
1362 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1363 JSONText in ECMA-262) is JSONValue, not JSONObject.
1365 --- 4.0.0 2010/01/20
1367 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1368 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1370 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1371 POSIX/Unix builds .so with major version 4.
1373 Remove old LOG_-defines from log.h. They have been obsolete and
1374 undefined by default for the last 5 years.
1376 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1378 GFS: Remove socket (int *fd) from search_rr handler. The socket
1379 descriptor ptr is a facility that allowed a search handler to supply
1380 a socket which would serve as a callback - when search was complete.
1381 This facility has now been in use for years.
1383 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1384 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1385 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1386 returns 'const char *' rather than 'char *. The returned string is
1387 read-only and should not be modified by applications. COMSTACK cs_close is
1388 now a void function - it no longer returns int. No applications check for
1389 the value and the implementations has always returned 0.
1391 ZOOM: use size_t for scan hit counts and str size. Functions
1392 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1393 occ (hit count) and len (string length) are now of type size_t pointer
1394 rather than int pointer. This is to be able to represent large hit counts
1395 and to also just to use the proper type for string length (strlen result).
1397 New JSON parser. Refer to include/yaz/json.h .
1399 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1400 Used to be int in some cases. Many wrbuf_-functions used to return an int
1401 indicating some length.. These return values were never used. And so they
1404 ODR: odr_malloc, odr_total now takes size_t for size.
1406 clone_z_type: fix leak; occurred for encoding failures.
1408 --- 3.0.52 2009/12/03
1410 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1411 bug was introduced in 3.0.51.
1413 --- 3.0.51 2009/12/02
1415 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1417 tcpip comstack: fix leak for getaddrinfo.
1419 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1420 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1421 Decoding of SRU "path" database is performed by private function
1422 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1423 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1425 yaz-client: honor base command for SRU. Change when database setting
1426 is applied for SRU and ensure it is kept when a connection is reset.
1427 Change also the way errors are displayed or SRU (decoding of packages).
1429 --- 3.0.50 2009/11/02
1431 Add support for extra request / response data for SRU codecs and GFS.
1432 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1433 for extra data response buffer and length. For the GFS, both request
1434 and response data (XML) is carried in extra_args and extra_response_data
1435 for the search handler. Patch by Ko van der Sloot.
1437 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1438 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1439 10010). This fixes bug #2113.
1441 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1442 cmdfile included a 'quit' command that would result in a memory violation.
1444 --- 3.0.49 2009/10/01
1446 Make a number of functions defined in xmlquery.c static. These have
1447 never been declared in a public header file (yaz/xmlquery.h) and was
1448 made public by mistake.
1450 Improve speed of character conversions (iconv utilities). This makes
1451 conversions from MARC-8 faster.
1453 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1454 unless type desired is "raw". This will prevent type "xml" from
1455 returning ISO2709 .. Which obviously can not be XML parsed.
1457 Fix memory leak in ZOOM that would occur if option apdulog was used
1458 on a re-used connection.
1460 Frontend server logs HTTP requests.
1462 Frontend server now sends Z39.50 close when it times out (sesssion has
1463 been idle for too long). Versions 2.0.30 and earlier also sent close.
1464 But due to a mistake this was disabled in all versions after that, i.e.
1465 the server would just close the socket immediately.
1467 yaz-client emits a better message when receiving an unrecognised
1468 userInformationField.
1470 Skip zero-length subfields when decoding ISO2709. This rare case happens
1471 if a record has two FS characters in a sequence. Without this patch
1472 there would be a reference beyond char array in using_code_len fragments
1475 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1477 --- 3.0.48 2009/08/28
1479 The show command offered by the zoomsh command now takes a 3d optional
1480 parameter type which is what is passed to ZOOM_record. If the type
1481 argument is omitted, "render" is used.
1483 RPN to CQL conv may use USE string attributes (bug #2978).
1485 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1487 --- 3.0.47 2009/07/08
1489 Function yaz_xml2query allows a diagnostic element in the PQF XML
1490 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1491 code and additional info respectively.
1493 The BER BOOLEAN is now the integral type Odr_bool which still happens
1494 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1495 typedef'd to Odr_int. This is still an integral 'int', but it may be
1496 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1497 ASN-1 compiler as well as programs has been updated to use the new types.
1499 --- 3.0.46 2009/06/08
1501 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1502 only the bibliographic record was rendered. For type=opac, an OPAC
1503 record is only returned if it is present.
1505 iconv: small fix for encoding of advancegreek.
1507 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1509 yaz-client: option auto_reconnect=on really reconnects.
1511 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1513 server: avoid null ptr ref for for yaz_poll errors.
1515 build: fix RPM build for RHEL 5.3.
1517 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1519 --- 3.0.45 2009/03/31
1521 Fixed bug #2709: TCP connect returns Invalid argument.
1523 Fixed compilation for mingw.
1525 Honor charset for raw records (ZOOM_record_get).
1527 Fixed use of errno for threaded mode that was seen on Solaris 10.
1529 Fixed argument passing with blanks in value for Windows Service.
1531 Disable YAZ' own log rotate by default (no 1 GB limit).
1532 The variable l_max_size which specifies the log file limit is set to 0
1533 (DISABLED): This is due to the fact that YAZ is most often deployed using
1534 logrotate. Also YAZ can not perform log rotate because of unsufficient
1535 permissions (setuid).
1537 --- 3.0.44 2009/02/17
1539 List supported encodings in man page for yaz-iconv.
1541 Fixed missing SSL libs for --libs output
1543 Re-established OID record syntax application-xml. Nobody should use it
1544 but we don't want to change soname because of this symbol being absent.
1546 --- 3.0.42 2009/02/02
1548 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1550 Added member named_result_sets for init handler struct for the GFS. This
1551 allows a server to disable named result sets.
1553 Removed OID record syntax application-xml.
1555 Added support for rule-based transliterator for ICU wrapper of YAZ.
1557 Fixed bug #1902: yaz-icu XML output.
1559 Make YAZ checks Emacs friendly.
1561 BITSTRING value shows value. Bug #2346.
1563 ISO2709 decoding: skip control characters from indicator data.
1565 Omit sort key by default in yaz-icu's output.
1567 Allow combined single char options (again) for YAZ' options function.
1569 Utility yaz-marcdump got option to display YAZ version (-V).
1571 Allow YAZ to use ICU 3.4.
1573 Added new ICU test case which illustrates removal of diacritics.
1575 --- 3.0.41 2008/12/29
1577 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1579 --- 3.0.40 2008/12/29
1581 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1584 Fixed bug #2352: yaz-marcdump crashes for certain record.
1586 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1588 Added support for Danmarc2 to UTF-8 conversion.
1590 Added support for ISO5426 to UTF-8 conversion.
1592 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1593 implementation version.
1595 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1597 --- 3.0.38 2008/11/10
1599 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1600 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1602 ZOOM C now interprets databaseName option for ZOOM connection as path
1605 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1607 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1609 Dummy Libxml2 types no longer defined in headers of YAZ'.
1611 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1614 --- 3.0.36 2008/09/26
1616 Various ODR chapter fixes.
1618 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1620 Added missing source for Windows compilation, mutex.c.
1622 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1624 For SRU connections in ZOOM all records up to "count" are now fetched.
1626 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1627 in Windows due to bad error handling for Libxml2.
1629 Added facility for sending arbitrary records (ASN.1 any) using
1630 ZOOM C's Extended service update. Patch by Sam Reynolds.
1632 New options for ZOOM C's connection, logapdu which makes ZOOM log
1635 --- 3.0.34 2008/06/18
1637 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1639 --- 3.0.32 2008/06/12
1641 Fixed memory violation that could occur when decoding UTF-8. This bug
1642 was only present in 3.0.30 of YAZ.
1644 --- 3.0.30 2008/06/06
1646 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1647 GNU TLS is used by default (if found).
1649 yaz-ztest returns OPAC records if a client asks for OPAC.
1651 Improved speed of MARC-8 encoding.
1653 Added support for lossy and loss-less MARC-8 encoding.
1655 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1657 Added new Windows Service wrapper (sc).
1659 yaz-client's itemorder command may now send a file.
1661 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1663 Added new function yaz_log_xml_errors.
1665 Allow (but warn) unknown XML attributes in MARCXML parsing.
1667 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1669 The UTF-8 to MARC-8 conversion now uses a different set of characters
1670 for Greek symbols. Bug #2120.
1672 --- 3.0.26 2008/02/21
1674 Added yaz_daemon (daemon.h).
1676 Fixed bug #2068: pkg-config trouble
1678 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1680 --- 3.0.24 2008/01/28
1682 Document --with-xml2 option.
1684 Added OPAC XML XSD (etc/opacxml.xsd).
1686 Allow glob mask for name attribute in retrieval element for the
1687 generic frontend server's retrieval facility.
1689 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1690 except POLLIN/POLLOUT.
1692 Fixed error handling in cs_listen. Bug #2037.
1694 --- 3.0.22 2008/01/20
1696 Fixed version in yaz/yaz-version.h.
1698 Fixed bug #2027: Crash when closing connection.
1700 Changed configure so that ICU support is only enabled if only ICU
1701 and Libxml2 is available (because the ICU chain is XML based).
1703 --- 3.0.20 2008/01/15
1705 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1706 is built. Only this DLL depends on the ICU runtime.
1708 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1709 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1711 Changed license of CCL module to 'Revised BSD'. After consultation with
1712 remaining members of the original EUROPAGATE consortium, we are re-issuing
1713 the CCL module without a separate license. The software was developed by
1714 Index Data as part of a research project. The special license was included
1715 to help feed usage information back to the project consortium to support
1716 project evaluation. At this time, the project consortium has long-since
1717 disbanded, and the majority of the original principals have retired. At the
1718 same time, we have significantly modified the software during the following
1719 years, to the point where very practically no original code remains. To
1720 simplify re-use of the software, we have contacted those members of the
1721 consortium who could be reached, and agreed to re-issue the module as a
1722 proper part of the YAZ package.
1724 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1726 CQL closer to being version 1.2 compliant. CQL also allows free-form
1727 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1730 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1731 bug could make Extended services handling crash in the ZOOM layer. This
1732 bug was only present in YAZ 3.0.18.
1734 --- 3.0.18 2007/12/19
1736 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1739 yaz-marcdump reads and writes collection wrapped records.
1741 Handle OPAC for record conversion module.
1743 Fixes for ICU wrapper.
1745 Allow ICU libs to be controlled with --with-icu .
1747 --- 3.0.16 2007/11/12
1749 Added yaz_poll which is a wrapper for select/poll. When poll is available
1750 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1751 sockets to be in use.
1753 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1754 functionality through an XML based configuration (ICU chain). This system
1755 is useful for search facilities such as Pazpar2 and Zebra that needs to
1756 perform tokenization of indexed material. The ICU code in a separate
1757 library libyaz3_icu.a.
1759 Added HTTP tunnel facility for COMSTACK, bug #1752.
1760 This is a facility that allows a Web proxy, such as squid, to tunnel
1761 Z39.50 traffic. This facility is "transparent" to must applications
1762 using YAZ. It's enabled by using pseudo transport connect: followed by
1763 the proxy address, followed by command, then follwed by he regular
1764 "virtual" addresss. For example,
1765 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1767 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1769 --- 3.0.14 2007/09/21
1771 Fixed bad memory reference in ZOOM_record - cuased by member not being
1772 initialized. This was a problem only in YAZ 3.0.12.
1774 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1775 fields were not removed.
1777 Changed the way C code is generated from codetables.xml. Made a MARC-8
1778 conversion trie for each characterSet section rather than codeTable.
1779 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1780 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1782 --- 3.0.12 2007/09/12
1784 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1785 from ZOOM_record_error).
1787 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1789 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1791 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1793 Better SRW-to-Bib-1 diagnostic mapping.
1795 ZOOM C and yaz-client announces SRU version 1.2 by default.
1797 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1800 Fixed in yaz_sru_decode to allow other version than 1.1.
1802 --- 3.0.10 2007/08/22
1804 Added support for SRU scan for ZOOM.
1806 Added support for the use of the older versions or Extended Service
1807 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1808 set to the version , 1=first, 2=second, 3=third. The third version is
1809 what ZOOM C has used so far. And that, obviously, is the default.
1811 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1812 therefore in Zebra and in SimpleServer-based applications). The new
1813 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1814 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1815 which is passed into the back-end search callback function.
1817 Added support for HTTP Basic authentication in clients: the SRU/W
1818 codec encodes the username/password elements of the PDU structure
1819 appropriately, and these may be set using the "user" and "password"
1820 options in ZOOM-C applications (the same options that are used for
1821 Z39.50 authentication).
1823 --- 3.0.8 2007/06/25
1825 Fixed bug #1208: SSL appears to be broken in ZOOM.
1827 Fixed bug #1206: Libxml2 include path weirdness.
1829 Added oid_name_to_dotstring.
1831 Allow elementSetName to be specified for ZOOM C record update.
1833 Allow waitAction to be specified for ZOOM C based for Extended Services.
1835 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1836 syntax OID. Bug introduced in YAZ 3 series.
1838 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1840 --- 3.0.6 2007/06/06
1842 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1843 directory. yaz-client now reads commands from file given by option -f
1844 if specified; then tries to read .yazclientrc in current directory.
1845 Failing that, it reads .yazclientrc from user's home directory.
1847 Added support for correlationInfo Note and ID for Record Update via
1850 Added yaz-client command querycharset which specifies character set for
1851 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1852 (termListAndStartPoint).
1854 Charset ISO5428:1984 is an alias for ISO5428-1984.
1856 Implemented a way to perform scan in a result set using Z39.50. This
1857 is achieved by attaching the result set name in the characterInfo
1858 (type InternationalString) of OtherInformation in the Scan Request PDU.
1859 The result set is identified in the otherinformation by the new OID:
1860 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1861 This allows for scan in result set and faceted search . Zebra did some
1862 of this in the APT term using attribute type 8 and value being result
1863 set. Using the OtherInformation approach for this is cleaner and easier
1864 to work with in proxies and the like. This facility can be used in
1865 yaz-client using new command setscan which takes a result set as first
1866 argument, start position (APT) as second.
1868 Changed decoding of SRU XML packed records to deal with servers that
1869 have recordData with XML data with multiple root nodes. Also make
1870 comparison for recordPacking case insensitive. Again, one server
1871 returns "XML" where others return "xml".
1873 For SRU responses allow Content-Type application/xml as well as text/xml.
1875 --- 3.0.4 2007/05/21
1877 Fixed bug in character set conversion of BER strings. Bug introduced
1880 --- 3.0.2 2007/05/08
1882 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1884 For OID class, use oid_class consistently.
1886 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1889 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1890 character set for bibliographic information interchange". By Giannis Kosmas.
1892 Added documentation on new OID API.
1894 --- 3.0.0 2007/05/02
1896 Changes to generic frontend server interface: added new member
1897 'query_charset' for bend_initrequest structure. A backend init handler
1898 should set this member to its native character set for query terms.
1899 When defined, the frontend server logic will announce this character set
1900 to a client if the negotiationModel bit is set by the client. All server
1901 implementors are encouraged to specify this. If a backend server does not
1902 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1904 Added CCL utility to remove terms (stop words) from resulting RPN
1905 tree. This is handled by functions with prefix ccl_stop_words_ .
1907 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1908 terms in RPN queries.
1910 Clean-up the CCL API. Moved some internal structures from ccl.h to
1911 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1912 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1913 This is replaced by ccl_parser_find_str which takes a string instead.
1915 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1916 libyaz.la is the core of YAZ except the generic frontend server and
1917 does not depend on POSIX threads anymore. libyaz_server.la is the
1918 generic frontend server facilities and uses POSIX thread functionality
1919 if available. The libyaz.la no longer depends on POSIX threads because
1920 the number of global structures is limited. NMEM no longer re-uses blocks
1921 between threads ; it simply free's memory immediately but allocates in
1922 "large" chunks as usual. We don't expect any performance penalties
1923 because of this. The yaz_log system is still using a global log_level so
1924 caution must be taken when modifying it with yaz_log_init_.. +
1925 yaz_log_mask_str. This, however, should not cause any trouble because
1926 these functions are called during initialization of application code
1927 anyway. `yaz-config --libs server` returns libs for server applications;
1928 `yaz-config --libs` returns libs for non-server applications.
1930 New OID database - with public definitions in oid_db.h. Removed old OID
1931 database including the head oid.h and definitions such as enum oid_value
1932 and struct oident. The new OID database uses the same string names as
1933 before but the 'protocol' is gone. There are now only two representations
1934 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1935 converts from string to OID; functions with prefix yaz_oid_to_string
1936 converts the other way.
1938 Change to emit_term() in CQL-to-PQF query translation: when a term has
1939 the /regexp relation modifier, do not process it for leading and
1940 trailing "^" and "*", which have quite different meanings in regular
1943 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1944 write handlers no longer carries a 'last' parameter. This will make
1945 yaz_iconv flush "less" characters. A flush is performed by call to
1946 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1948 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1949 removed, because function yaz_query_to_wrbuf does the same.
1951 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1952 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1954 Deprecated MARC utility functions removed.
1956 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1959 Branch split: YAZ_2_1_55_branch
1961 --- 2.1.54 2007/03/16
1963 Fix to ZOOM-C so that transparent reconnection is properly handled on
1964 connections that are in asynchronous mode.
1966 Fixed compilation on OpenBSD 4.0.
1968 Large strings in GRS-1 records are now properly displayed in yaz-client.
1970 Added character conversion support for "advancegreek"; based on patch from
1973 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1974 sequence is met. Before the error was not set so it would be unknown.
1976 Adjust yaz-marcdump MARC reader so that it skips until record separator
1979 --- 2.1.52 2007/03/07
1981 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1982 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1983 fd_set structure used as a bitmask for the FDs to be selected on.
1985 Using ACX_PTHREAD macro to check for POSIX threads.
1987 Fixed have-vsnprintf check.
1989 --- 2.1.50 2007/02/23
1991 Fixes for configure on BSD. Bug #900.
1993 Added snprintf/vsnprintf wrappers for systems that don't have
1994 limits (heavens forbid).
1996 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1997 created before all previous tasks were completed and removed from the
1998 task queue, the new task could be removed by a mistake.
2000 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2002 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2004 Fixed bug #832: Problem with MARC/charset in yaz-client.
2006 Fixed bug #668: save command line history for yaz-client.
2008 Fixed bug #830: pkg-config support.
2010 --- 2.1.48 2007/01/23
2012 Extended ZOOM result set options with two options that may be read by
2013 a client: resultSetStatus and presentStatus with values as specified for
2015 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2017 Fixed bug #827: Using SSL fails on Debian etch.
2019 Fixed bug #826: Weird looking chars for set of MARC records.
2021 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2022 that is treated as an ItemOrder with itemRequest being an XML document
2023 external. The value of "doc" is the content.
2025 Extended the GFS search facility. New member of bend_search_rr
2026 'estimated_hit_count' signals that hits is known to be an estmate
2027 (higher or lower than real hit count). New member 'partial_resultset'
2028 signals that the search was partial (hit count is lower or equal than
2029 real hit count). For Z39.50, the information is stored in resultSetStatus
2030 member of SearchResponse APDU. For SRU, the information is signalled
2031 via SRU diagnostic 59: "Result set created with valid partial results
2034 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2036 --- 2.1.46 2007/01/13
2038 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2040 Added ZOOM_connection_peek_event.
2042 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2043 the following new functions:
2044 ZOOM_event_nonblock, ZOOM_connection_process,
2045 ZOOM_connection_get_{socket,mask,timeout},
2046 ZOOM_connection_fire_event_{timeout,socket}.
2047 The existing blocking event handler, ZOOM_event, is a wrapper for the
2048 + blocking ZOOM_event_sys_{poll,select}.
2050 Implemented function ccl_xml_config which parses XML version of CCL
2051 configuration (bug #798).
2053 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2055 Added timings utility (yaz/timing.h)
2057 --- 2.1.44 2007/01/03
2059 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2062 Fixed bug #779: Rotation of apdu.log fails.
2064 Fixed for character set conversions:
2065 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2066 Honor G1 set in MARC-8 decoding.
2068 --- 2.1.42 2006/12/17
2070 Fixed bug #775: char conversion does not handle Alternative UTF-8
2073 Implemented function yaz_marc_read_line which parses MARC line format
2074 records. There is a wealth of formats out there. So far, this function
2075 reads line records produced by yaz_marc_write_line.
2077 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2078 more generic and easier to remember(!) options: -i format and -o format
2079 which specifies input format and output format respectively - where
2080 format is one of "marc", "marcxml", "line", "marcxchange".
2082 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2083 does not print anything except warnings for records.
2085 For yaz-marcdump, added support for MARC split into files (-s) with a given
2088 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2089 spec, at http://www.loc.gov/standards/sru/record-update/
2090 This has changed the binary layout of the following structs:
2091 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2092 bend_update_rr . Patch by Ko van der Sloot.
2094 Added GFS utility function bend_assoc_is_alive which returns 1 if
2095 association is still alive (client is connected); 0 otherwise (client
2096 closed connection). This allows busy servers to stop working for
2099 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2100 been a separate piece of software. This version of ziffy has been modified
2101 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2103 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2105 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2106 Client code may now interrogate options such as "init_opt_sort" to
2107 find out whether the server claims to support various options.
2109 --- 2.1.40 2006/11/27
2111 Added utilities yaz_{set,get}_esn to set/get element set name from
2114 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2115 of YAZ and has been so since YAZ 2.1.10.
2117 Implemented ZOOM_record_error which returns error information for
2118 record (surrogate diagnostic).
2120 --- 2.1.38 2006/10/31
2122 Updates for SRU Update by Ko van der Sloot:
2123 1. Changed name from "operation" to "action"
2124 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2125 versions in the code, marked as 'backward compatible'.
2126 3. Added diagnostics for SRU Update.
2128 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2130 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2132 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2134 For GFS, fixed problem with SRU diagnostic 'First record position out of
2135 range' being issued for 0 hits.
2137 zoomtst10 part of Windows Build.
2139 --- 2.1.36 2006/10/13
2141 Implemented yaz_filepath_comp which splits a path into file path
2142 components (required by Zebra 2.0.3+).
2144 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2145 BSD inspired license until now so this should not have any real impact on
2146 anybody. See http://www.opensource.org/licenses/bsd-license.php
2148 Fixed bug #687: Missing log lines.
2150 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2153 Fixed bug #689: SRU diagnostics to be added.
2155 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2156 whether a connection is idle (no more work do do).
2158 --- 2.1.34 2006/10/04
2160 Change type of optval from long to int for invocation of setsockopt with
2161 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2163 Added support for specifying the max log file size for the Generic
2164 Frontend Server. The size is given with option -r.
2166 --- 2.1.32 2006/09/21
2168 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2170 --- 2.1.30 2006/09/17
2172 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2175 Fixed bug in Generic Frontend Server that could cause a server to stop
2176 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2178 For the generic frontend server, the maximum record size is used as maximum
2179 size of incoming packages (SRU + Z39.50). The value until was previously
2180 only used in Z39.50 Init negotiation and, later, in a session controlled
2181 sizes of records returned. This is controlled using -k option. It can be
2182 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2184 --- 2.1.28 2006/09/04
2186 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2189 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2191 New option for yaz-marcdump -lpos=value which allows setting a portion
2192 of MARC header to a certain value.
2194 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2196 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2197 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2199 --- 2.1.26 2006/08/15
2201 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2204 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2206 --- 2.1.24 2006/08/08
2208 Fixed MARC ISO2709 encoding routines to deal with character set
2211 Minor changes to GFS logging. Database included in search request log
2214 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2215 cached/multiple records.
2217 Shared libraries are built by default on Unix+configure.
2219 Changed cql2pqf transformation to use a different evaluation order. The
2220 new order is: always, relation, structure, position, truncation, index
2221 and relationModifier. Old order was: always, relation, relationModifier,
2222 structure, index, position, truncation. Note that the the latter ones
2223 override former ones for identical attributes.. The new scheme means that
2224 it is possible to override any existing attribute with a relationModifier.
2225 And also that it is possible to override everything for the index rule
2226 (except the ones listed in relationModifier). No order is perfect but this
2227 one, we believe, covers more real cases.. The "always" should have been
2228 called "default", since the attributes there can be overridden with all
2231 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2232 compilation phase, but also for yaz-config --cflags output. This allows
2233 us to have public headers with Libxml2 stuff in them . It should also,
2234 eventually, make Libxml2 checks redundant in packages using YAZ, such
2237 --- 2.1.22 2006/06/15
2239 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2240 stored in uri, message and details.. Previously diagnostics were stored
2241 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2242 compatibility.. but he's probably the only one affected, so.
2244 Added support for CCL, compiled on the client side, in ZOOM-C. This
2245 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2246 input; the resulting query objects can be used for for searching with
2247 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2249 YAZ' configure searches for OpenSSL by default.
2251 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2252 SL_CTX_use_certificate_file. See
2253 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2254 for more info. Thanks to Ko van der Sloot.
2256 --- 2.1.20 2006/06/02
2258 Bug #600: SRU GET, POST support for yaz-client. Introduced
2259 command 'sru' which selects method SOAP/GET/POST.
2261 Allow missingValueAction to be specified for the sortspec string -
2262 function yaz_sort_spec. By default, the missing value action is null.
2263 Use ! to specify "abort". Use = followed by stringvalue to specify default
2266 Ensured that Present-handler (if defined) is called in GFS before any call to
2267 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2268 searchRetrieve requests.
2270 Documentation for YAZ is now based on the Docbook XML/XSLT using
2271 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2272 is no longer depending on jade/openjade or docbook-to-man scripts.
2273 PDF is no longer part of the distribution - but can optionally be
2274 made using DSSSL/jadetex or FOP.
2276 Added retrieval handling support in Generic Frontend Server to support
2277 conversion between MARC/XML as well as XSLTtransforms. See
2278 etc/yazgfs.xml for an example.
2280 Added Authentication support to Generic Frontend Server in SRU
2281 mode. Authentication using HTTP Basic is supported, as is the use
2282 of 'x-username' and 'x-password' parameters in the request itself.
2284 Added support for a new character set MARC8s identical to MARC8 except
2285 that it converts combined characters to single Unicode characters in the
2286 Latin-1 range (when possible).
2288 --- 2.1.18 2006/04/24
2290 ASN.1 compiler 0.4: generates brief Doxygen file header for
2291 generated .h/.c files.
2293 Utility yaz_iconv now supports conversion to MARC-8.
2295 New facilities for the MARC module. The reading - and writing of
2296 content are separate methods for the yaz_marc_t handle. The following
2297 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2298 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2299 format). Write functions have prefix yaz_marc_write_.. The existing
2300 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2301 available. Removed support for OAI-MARC and simplexml (not the
2302 simplexml from PHP5).
2304 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2305 to be returned for this connection.
2307 --- 2.1.16 2006/03/31
2309 Allow multiple languages and charsets to be specified with
2310 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2311 negcharset iso-8859-1,utf-8
2313 Translation of proximity nodes from CQL into PQF now works.
2315 Moved to automake 1.8, 1.9.
2317 Added function yaz_log_set_handler which allows a log handler to be
2318 installed. This handler will be called for all log messages. Output
2319 to file is also produced; but that can be disabled by passing NULL
2320 fname to yaz_log_init_file.
2322 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2324 For SRW (including GFS), accept application/soap+xml as content-type
2327 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2328 produces NO stylesheet reference even if a default stylesheet is specified
2331 --- 2.1.14 2006/03/14
2333 Updated Windows package to include yazd.dll + yazd.lib for the
2334 Development component.
2336 If the environment variable YAZ_LOG is set, then it is used as a
2337 string indicating the default level of logging to use if not
2338 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2339 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2340 used as before. So, for example, to omit warnings from YAZ logging,
2341 export YAZ_LOG=-warn
2343 cql_transform() now map structure and other attributes before indexes,
2344 so that index-specific structures and other attributes can override
2345 defaults. So now a combination of mapping specifications such as:
2347 index.dc.date = 1=date-modified 4=5
2348 does the right thing.
2350 cql_transform() now also respects the "always" mapping specification,
2351 which establishes an initial set of attributes to be used for all
2352 terms except where overridden by more specific attributes associated
2353 with the index, relation or modifier.
2355 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2356 which mode to use; one of "post", "get" or "soap" (SRW, default).
2358 Fixes for yaz_iconv routines: changed trie-based character set conversions
2359 to use only non-negative values for bit fields due to Sun's C compiler not
2360 supporting negative values.
2362 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2363 sequences where not read correctly. Fix by Rustam Usmanov.
2365 Updated win/makefile to use options, settings which makes things
2366 compile with VS C 2005.
2368 --- 2.1.12 2006/02/01
2370 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2372 In ZOOM socket code, use select instead of poll on MacOSX.
2374 ZOOM-C now support client-side compilation of CQL into RPN that is
2375 sent to the server, enabling CQL to be used against all Z39.50
2376 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2377 ZOOM_query object, and submit it using ZOOM_connection_search().
2378 The CQL-to-RPN translation uses a configuration file, the name of
2379 which must be specified in the Connection's "cqlfile" option.
2381 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2382 function, which takes as its start-term parameter a ZOOM_query object
2383 (which may have had either CQL or RPN set into it).
2386 --- 2.1.10 2005/11/29
2388 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2389 GFS to support this as well. Backend handler, bend_srw_update, does the
2390 update work. Code contributed by Ko van der Sloot.
2392 Allow retrieval of Search Result-1 information in ZOOM by the use of
2393 options that are attached to a result set. ZOOM documentation updated
2396 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2397 UTF-8 conversion. Patch by Raj Patel.
2399 Added option -m to GFS to control formatting of timestamps in log file.
2401 Added 'exit' as synonym for 'quit' in yaz-client
2403 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2404 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2405 for the new members. Patch by Ko van der Sloot.
2407 Added support for SRU POST. It is supported for content-type
2408 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2410 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2411 Instead make the library libyaz.la multi-threaded. Threading as a whole
2412 can still be disabled by configure option --disable-threads. Previosly,
2413 with older GLIBCs there were problems with MT libs under Apache. This
2414 has now been fixed a long time ago.
2416 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2419 CQL module modified to be case insensitive for relations/indexes/operations.
2421 Fixed bug in CQL transform code: incorrect value relationModifieder
2424 Added 'show all' command for yaz-client which retrieves all results
2427 Added new yaz-client, xmles, which takes a (private) OID and
2428 a document to be sent as an extended service request.
2430 Describe new yaz-client commands wait_response and set_auto_wait.
2432 Increase TCP/IP listener backlog from 3 (which I am guessing was
2433 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2434 that the socket will queue as many incoming connections as it's able
2435 to handle ongoing connections. In other words, it will never now
2436 refuse a connection that it would be able to handle merely because
2437 it's not got around to accepting() enough of the pending connections
2438 yet. This is the behaviour anyway under Linux, where the listen()
2439 argument is ignored; but not under BSD and on systems such as
2440 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2441 YAZ-based servers should now be uniform across operating systems in
2444 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2445 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2446 This allows yaz-marcdump to read large MARC batches (>2 GB).
2448 Modified all YAZ source files - except the source which is auto-generated
2449 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2452 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2453 corresponding to the existing *_setl() function. These allow option
2454 values containing arbitrary valuues.
2456 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2457 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2458 except that it returns an indicator of whether or not the sort
2459 criterion was accepted (0 for OK, -1 for invalid).
2461 --- 2.1.8 2005/06/07
2463 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2464 MARC output rather than returning "new" buffer.
2466 yaz-client warns about unknown init options.
2468 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2470 --- 2.1.6 2005/05/24
2472 Added support for SRW sort in Generic Frontend Server. Patch
2473 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2474 sortKeys - or NULL if none is provided.
2476 Fixed bug #307: It was impossible to specify indefinite/no timeout
2477 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2480 Added support for multiple languages and charsets to be specified in
2481 ZOOM. Each charset/language is separated by a blank. If negotiation is
2482 in effect in init-response, Option
2483 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2484 Code based on patch by Vasiliy Osadchuk.
2486 Fixed bug #306: infinite recursion that occurred when calling
2487 yaz_log_level_init as the first call (before other log level or
2490 Fixed bug in scan handling in front end server: if preferred-Position-In-
2491 Response was non-present, a NULL pointer referece was performed.
2493 --- 2.1.4 2005/04/26
2495 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2496 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2497 now defined for all those error codes. So instead of putting 109 in
2498 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2499 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2501 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2504 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2506 Program yaz-client now exits and produces an error message if multiple
2507 Z39.50 servers are specified on the command line (none or one allowed
2510 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2513 --- 2.1.2 2005/03/16
2515 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2517 Fixed bug #272: Preserve spacing for CCL terms.
2519 --- 2.1.0 2005/03/14
2521 Added support for virtual hosts and multiple backend servers for
2522 the YAZ frontend server. The configution is XML based and
2523 support specificition of CQL to RPN mappings and explain information.
2524 See section "Virtual Hosts" in the YAZ manual.
2526 Extended OPAC display utility. OPAC display utility renders
2527 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2528 to supplement yaz_marc_decode_wrbuf.
2530 Fixed a bug in MARC decoder that could caused it to crash for some
2531 invalid MARC records. More diagnostics and warnings where added in
2532 XML output (warnings, etc are stored in comments).
2534 --- 2.0.34 2005/02/08
2536 Fixes for UNIX domain sockets. Bug #261.
2538 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2540 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2541 Added yaz_marc_subfield_str which defines subfield lead string which is
2542 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2543 yaz_marc_endline_str which defines end of fields string used in
2544 YAZ_MARC_LINE format. Default string is newline.
2546 Experimental support for MarcXChange. This format can be produced
2547 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2548 http://www.bs.dk/standards/MarcXchange.xsd
2550 Added yaz-client commands scansize that sets maximum number of
2551 entries to be returned by scan.
2553 --- 2.0.32 2005/01/11
2555 Added support for SRW scan in yaz-client and Generic Frontend Server.
2557 * Added whereInList member to SRW Scan Term.
2559 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2561 Fixed NMEM system to return aligned blocks on the smallest boundaries
2562 that are suitably aligned for all possible types on the particular
2563 architecture YAZ is being built for.
2565 --- 2.0.30 2005/01/04
2567 Fixed numerious warnings that was issued with newer versions of GCC.
2569 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2570 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2573 Make YAZ Generic Frontend Server slightly faster.
2575 Enhance (and reduce) logging for Generic Frontend Server.
2577 Revert YAZ log system so that it flushes every write operation
2578 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2580 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2581 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2582 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2583 will effectively disable old definitions.
2585 --- 2.0.28 2004/11/09
2587 Added yaz_log_time_format which specifies log format using
2590 Added yaz_log_module_level which returns mask for a module. Value
2591 is non-zero mask a if module is enabled; zero if disabled.
2593 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2594 in include/yaz/cql.h.
2596 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2598 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2600 Fixed bug #172: RPM builds does not enable SSL.
2602 Doxyfile.in part of dist. Doxyfile generated by configure.
2604 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2605 are given and the corresponding component does not exist.
2607 Extend CCL documentation in YAZ reference. Describe r=r.
2609 --- 2.0.26 2004/10/01
2611 Fixed MARC->MARCXML conversion to properly deal with
2612 fields, subfields, indicators having non-ASCII characters.
2614 Fixed MARC->MARCXML conversion so that ASCII control characters
2615 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2618 Added YAZ GFS support for conversion from Z39.50 surrogate
2619 diagnostics to SRW surrogate diagnostics.
2621 Bug fix: YAZ GFS did not return schema in explainResponse.
2623 --- 2.0.25 2004/09/30
2625 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2626 now converts recordSchema to elementSetName as well as schema URI.
2628 Fixed bug in COMSTACK that prevented HTTP request packages from being
2631 --- 2.0.24 2004/09/29
2633 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2634 does not require white-space before and after the dash in a range, e.g.
2635 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2638 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2639 due to new GCC removing "redundant" code.
2641 Added yaz-client commands scanpos and scanstep that sets preferred
2642 position and step-size for scan.
2644 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2646 Added CCL utility ccl_qual_buf which parses one or more CCL
2647 spec lines in a buffer.
2649 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2650 of name and value - ignoring empty lines and comments.
2652 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2654 Added odr_get_element_path which returns current element path for an
2655 ODR handle. This utility is useful in error handling or user-defined
2658 Added ODR_PRINT utility odr_set_stream which is is a more generic
2659 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2660 to a write function and pointer to close function. The close function - if
2661 non-NULL - will be called during odr_destroy.
2663 Fixed bug in CCL parser where truncation char was not removed from
2664 right side when truncation=both was in effect.
2666 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2669 --- 2.0.23 2004/08/11
2671 Fix buffer overrun in CQL parser when dealing with proximity (%).
2673 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2674 to UTF-8/UCS conversion is now only based on codetables.xml.
2676 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2678 --- 2.0.22 2004/08/06
2680 Add support for more "commit changes" in ZOOM (uses Extended Services).
2682 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2685 Yet another small fix for configure of SSL.
2687 --- 2.0.21 2004/05/14
2689 Fix SSL libs for configure when --with-openssl=DIR is given.
2691 --- 2.0.20 2004/05/10
2693 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2695 SSL comstack now uses yaz.pem certificate file on server side
2696 by default. Certificate filename can be configured by calling
2697 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2699 Fix bug regarding multiple calls to ZOOM_connection_connect.
2701 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2703 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2704 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2706 ZOOM now allows inspection of X509 peer certificate for verification.
2707 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2709 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2710 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2711 as "modular" but it simplifies things.
2713 Added cs_get_peer_certificate to that returns peer X509 PEM.
2715 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2716 NULL if SSL is unavailable.
2718 Documentation about MARC decoding tools.
2720 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2722 --- 2.0.19 2004/03/30
2724 Rename CHANGELOG to NEWS to follow GNU style packing.
2726 Fix bug with missing initialization of member in init_diagnostics.
2727 This bug affects threaded version of GFS server.
2729 --- 2.0.18 2004/03/20
2731 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2734 Ensure zlib.dll is packed with Windows install.
2736 --- 2.0.17 2004/03/17
2738 Fix encoding of xsd:string to use text instead of CDATA.
2740 Fix endless loop in CQL parser with unbalanced ".
2742 Use a more compact way to store MARC-8 conversion tables.
2744 --- 2.0.16 2004/03/16 Debian only
2746 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2749 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2754 --- 2.0.15 2004/03/01
2756 Another fix for decoding of XML packed records.
2758 --- 2.0.14 2004/02/25
2760 Fixes for Chunked encoding. White space not ignored after length spec.
2762 Update NS and use default NS for SRW diagnostic elements.
2764 --- 2.0.13 2004/02/23
2766 Implement ZOOM_resultset_cache_reset which resets record cache.
2768 Implement ZOOM_resultset_sort which sorts a result set.
2770 Implement chunked HTTP transfer.
2772 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2774 --- 2.0.12 2004/02/16
2776 Added member 'schema' to bend_explain_rr structure so that backend
2777 can specify explain record identifier. Defaults to Zeerex 2.0.
2779 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2781 --- 2.0.11 2004/02/16
2783 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2786 Added init command for yaz-client which sends "extra" init request.
2788 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2789 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2791 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2793 Make ZOOM error code for "invalid query".
2795 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2797 --- 2.0.10 2004/02/05
2799 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2802 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2804 Added option -p <file> to make Generic Frontend Server to write PID file.
2806 Added option -D to put Generic Frontend Server in background on its own.
2808 Make ZOOM C recognize option "password". If unset, "pass" is used
2809 (for backwards compatibility).
2811 Fixed a bug in Generic Frontend Server that could make it crash if a
2812 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2815 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2816 Must be issued before open, in order to be in effect.
2818 --- 2.0.9-6 2004/01/12 Debian/Windows
2820 Make the SRU server more picky WRT unknown params, etc.
2822 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2824 New YAZ client command, options, that sets Z39.50 options.
2826 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2827 options from a string of tokens (one token for each option bit).
2829 Update SRW diagnostic code messages.
2831 --- 2.0.9-5 2004/01/07 Debian/Windows
2833 Handle user defined stylesheet for SRW/SRU.
2835 --- 2.0.9-4 2004/01/06 Debian/Windows
2837 Fix bug in decoding of Content-Length.
2839 --- 2.0.9-3 2004/01/06 Debian/Windows
2841 Fix a bug with decoding of XML packed records.
2843 --- 2.0.9-2 2004/01/05 Debian only
2845 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2847 Fix bug in SRW/SRU diagnostics decoding.
2849 --- 2.0.9 2004/01/05
2851 Fixed bug in Generic Frontend Server which could drop records exceeding
2852 preferred message size. Reported and fixed by Irina Dijour.
2854 Fixed calculation of package size for structured records in Generic
2855 Frontend Server. Reported and fixed by Irina Dijour.
2857 Fixed namespace for SRW/SRU diagnostics.
2859 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2861 --- 2.0.8 2003/12/22
2863 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2864 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2867 CQL changes to reflect recent changes to the specification:
2868 * Documentation talks about context sets instead of index sets.
2869 * Documentation talks about indexes instead of qualifiers.
2870 * The CQL-to-PQF transformer's configuration file now uses
2871 "index.set.name = <attributes>" instead of the old form
2872 "qualifier.set.name = <attributes>". (Both forms are still
2873 understood but the latter is deprecated.)
2874 * CQL terms with no explicit index specified are now interpreted as
2875 cql.serverChoice instead of srw.serverChoice (which of course
2876 behaves exactly the same.)
2878 --- 2.0.7 2003/12/16
2880 MARC conversion can now generate ISO2709 output in another
2881 character set. yaz-marcdump uses this facility if you invoke it
2884 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2885 functions from there can be used from C++.
2887 --- 2.0.6 2003/12/04
2889 Frontend server now transfers memory from decoded packages to stream
2892 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2893 references to show up.
2895 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2896 the ZOOM Abstract API. The older names for the same options are still
2897 also supported for the benefit of old applications.
2899 ZOOM-C supports "implementationId" and "implementationVersion" options
2900 to go along with "implementationName". These allow the user code to
2901 specify identification strings to be sent to servers.
2902 Add OID for the new ExtLite attribute set.
2904 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2905 as requested/supplid by Ere Maijala <ere@atp.fi>
2907 For generic frontend server, reverse the order of
2908 "toolkit-supplied / application-supplied" strings sent as implementationId,
2909 Name and Version. Also, remove the spaces around the slash. This brings
2910 the GFS in line with the behaviour of ZOOM-C on the client side.
2912 Add function ZOOM_scanset_display_term.
2914 yaz-client shows scan displayTerm if present.
2916 Utility yaz-iconv is now installed by default along with the man page
2919 Extend configure check for OpenSSL to use pkg-config where available (such
2922 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2923 server to specify uid/gid/mask for socket using the format
2924 unix:[user=uid,][group=gid,][umask=mask,]file=path
2925 If file= is omitted the existing format is assumed, e.g.
2927 in which case the mask is 0666 (rw for everybody).
2929 Major restructure of YAZ source. All source in libyaz is in src directory.
2930 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2931 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2933 Added man page for utility yaz-marcdump (used to be called marcdump).
2934 yaz-marcdump is installed by 'make install'.
2936 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2937 of incoming package failed.
2939 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2941 Change prototype of odr_perror: add const to message string.
2943 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2945 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2946 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2947 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2948 DNS lookup. There should not be any compatibility problems with this
2949 assuming that blocking=1 or 0 is used.
2951 Fix bad reference in UNIX comstack in function cs_addrstr.
2953 Fix for compilation on AIX.
2955 The generic front-end server (server/seshigh.c) now supports returning
2956 Init diagnostics to the client in User-information-field, in
2957 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2960 --- 2.0.4 2003/09/04
2962 Allow any CQL relation (not just all,any,exact,scr).
2964 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2965 that features the same UI.
2967 Implemented command update0 in YAZ client which is equivalent to
2968 update but uses old of Ext Update ASN.1.
2970 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2971 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2972 Previously no OID was used for this info.
2974 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2975 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2976 returns 'malformed search term' otherwise.
2978 SortResponse member resultCount now set to NULL in sort handler of
2981 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2984 Add three new utility functions for translating OIDs between various
2985 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2986 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2987 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2988 char *oid_to_dotstring(const int *oid, char *oidbuf);
2989 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2991 Reverted modifications for ES Update definition for z_IU0Update
2992 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2993 is back to YAZ 2.0.2.
2995 String value attributes for CCL parser.
2997 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2998 which their FirstSearch server returns in Init responses, sometimes
2999 carrying useful diagnostic information when Init fails. This has the
3000 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3001 "z39.50/oclcui.asn", where its definition is somewhat different from
3002 what OCLC document on their web-site, as required to interoperate with
3005 Support for anonymous authentication in yaz-client. Use the command
3008 * Fix the OID of the Index Data-local "admin" Extended Service from
3009 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3010 the 1000, which indicates a locally-defined OID, was a mistake.
3012 --- 2.0.3 2003/06/20
3014 Fix CCL directive @case handling so that it affects string match for
3015 both CCL keywords and qualifiers.
3017 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3018 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3019 Decoder has been updated with ASN.1 changes as listed in
3020 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3021 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3022 z_IUUpdate, remains unchanged.
3024 ZOOM_record_get may now return a record in a specific character set.
3025 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3026 "from" is the character set of record as returned by target. "to" is
3027 the character set to be returned. If omitted, "to" is UTF-8.
3029 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3031 New ODR utility, odr_getelement, which returns name of element for
3032 which encoding/decoding failed.
3034 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3035 in cases where a required element was omitted.
3037 Bug fix: some MARC8 sequences were not converted.
3039 New ZOOM option "step" which specifies number of records to be
3040 retrieved in one chunk. Used in conjunction with "start" and "count".
3042 SRW support for yaz-client. Use scheme http: to use it, e.g.
3045 yaz-client no longer does (un)intelligent character set conversions
3046 by default. Can be enabled with charset and marc_charset commands.
3048 xmalloc trace fix for 64-bit systems such as DEC alpha.
3050 Solaris 2.6 compile fix.
3052 New function, cql_strerror() translates SRW error codes, as returned
3053 by cql_transform_error(), into human-readable English strings. Used
3054 in yaz-client diagnostics when appropriate.
3056 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3057 converts it into a type-1 query which is sent to the server. This
3058 makes CQL available for use with all Z-servers, as opposed to the tiny
3059 minority that can handle CQL queries themselves.
3061 --- 2.0.2 2003/04/28
3063 New Debian package layout similar to the Redhat Package layout.
3065 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3066 and search result respectively.
3068 --- 2.0.1 2003/04/25
3070 Redhat package is now several packages: libyaz (runtime libraries),
3071 libyaz-devel (development and documentation, and yaz (utility programs).
3072 Package spec file by Morten Bogeskov.
3074 New member 'schema' in struct bend_fetch_rr which the name of requested
3075 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3076 handler MAY set this to reflect the schema of the returned record.
3078 New member 'display_term' in struct scan_entry. GFS now sets member entries
3079 and allocates scan entries to be filled by user scan handler. In previous
3080 version, entries member was allocated by the scan handler. That still works,
3081 but the GFS will ignore member display_term - assuming it was NOT set by
3082 the handler. The fact that the GFS now allocates the entries both allows
3083 for new members and makes a scan handler easier to write.
3085 Fix CQL lex buffer overflow.
3087 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3088 SRU default recordPacking is string.
3090 SRU protocol support for frontend server.
3092 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3094 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3096 Added scan for the ZOOM shell (zoomsh).
3100 * String Identifers for Schemas (Amendment 5).
3101 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3102 Old definition for schema
3103 Odr_oid *schema; /* OPT */
3108 Z_InternationalString *uri;
3109 #define Z_Schema_oid 1
3110 #define Z_Schema_uri 2
3113 * resultCount parameter to Sort Response (Amendment 1).
3114 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3116 Support for SRW 1.0 over HTTP. This is an optional feature and
3117 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3120 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3121 on the same port. SRW SearchRetrieveRequests are mapped
3122 to bend_init,bend_search,bend_fetch,bend_close.
3124 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3126 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3127 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3129 ZOOM connections are SRW based if schem http is used for hostname
3130 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3131 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3133 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3134 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3135 distance=n, order=true/false, relation=le, prox unit=word. If
3136 n is omitted, distance 1 is used.
3138 Fixed problem with C compiler include path in wrong order.
3140 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3141 on Solaris. Patch from Ko van der Sloot.
3143 New MARC decode API. All new functions operate on a yaz_marc_t
3144 handle. The most important new functions are: yaz_marc_create,
3145 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3146 decode and destroy respectively. Decoder can produce formats
3147 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3148 include/yaz/marcdisp.h.
3150 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3151 to UTF-8, UCS-32, wchar_t or Latin-1.
3153 * Prototypes for yaz_iconv_-functions moved to separate header
3154 include/yaz/yaz-iconv.h.
3156 Make a few private functions 'static' in unix.c. This prevents
3157 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3159 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3160 are set when Init Response is received.
3162 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3163 but returns diagnostic set as well.
3165 New function yaz_strerror which is a portable wrapper for
3166 strerror/strerror_r/GetLastMessage.
3168 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3169 is returned for MARC. If type is "oai", then OAI MARC is returned.
3171 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3174 --- 1.9.2 2002/11/26
3176 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3178 Fix bad race conditions on SIGTERM and terminate gracefully in
3181 Move retrieval (data1) module to Zebra since nobody seems to be
3184 Add GRS-1 render for ZOOM using same format as yaz-client.
3186 --- 1.9.1 2002/10/05
3188 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3190 Fix broken ESpec handling in data1 module.
3192 SGML reader parses comments and makes them part of the data1 tree.
3194 Added several type casts so that YAZ compiles as C++ code.
3196 ZOOM didn't handle PDU encoding failures properly.
3198 Added more Bib-1 diagnostics (approved extensions).
3200 GNU configure: better check for iconv.
3202 More portable use of accept, getpeername. Check for socklen_t. Use
3203 int/size_t if socklen_t is not defined.
3207 PQF parser rejects bad queries - including those with extra
3208 characters in them. PQF parser used to silently ignore that.
3209 Cleaner API for PQF added, which allows you to get detailed
3210 error information for bad queries (see yaz/pquery.h).
3212 Fixed bug in ZOOM_record_get for type "database".
3214 Implemented mini iconv library supporting conversions between
3215 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3217 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3219 --- 1.8.9 2002/08/20
3221 Fixed ZOOM C record cache so that preferredRecordSyntax and
3222 elementSetName is used to check for already fetched records.
3224 --- 1.8.8 2002/08/02
3226 Added three members in bend_initrequest structure to facilitate
3227 character set negotiation.
3229 Fixed a bug in frontend server that could cause indefinite
3230 loops under rare conditions.
3232 Revised character set utilities (charneg.h) so that encoding
3233 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3235 For PQF, directive @term <type> sets term type for Scan/Search.
3236 Here <type> is general, string, numeric, null. The term type
3237 is inherited - just like @attr.
3239 New call odr_set_charset that sets character set conversion for
3240 international-strings on a ODR stream. Prototype is:
3241 int odr_set_charset(ODR o, const char *to, const char *from);
3242 The InternationalString is still represented as C string in YAZ
3243 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3244 won't). On the protocol level, you can use any encoding.
3246 Support for UNIX sockets in ZOOM.
3248 Solaris recv sometimes returns errno == ENOENT. It is treated as
3249 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3251 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3252 both client and server. Code by Morten Bogeskov.
3254 --- 1.8.7 2002/05/22
3256 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3257 that they can be used directly from Visual Basic. You must recompile
3258 your windows APP if you're using ZOOM.
3260 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3261 Commands "lang" and "charset" sets language and character set respectively.
3262 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3263 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3265 Attributes from multiple CCL fields may be OR'ed rather than merged
3266 using directive "@field or". Fields are still merged by default -
3267 equivalent to "@field merge".
3269 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3272 Fixed bug in zget for parameter ExtendedServicesResponse.
3276 --- 1.8.6 2002/03/25
3278 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3280 Client displays USR.1:SearchResult-1 (hits per term).
3282 Additional Search Info for search in Generic Frontend Server.
3284 Fixed CCL parsing of "field=s".
3286 WIN32 installer - using the excellent NSIS software from nullsoft.
3288 Fixed CCL parsing of "field = - <number>".
3290 Added function yaz_marc_decode that decodes MARC for line mode
3291 display or XML (similar to that used by JZKit).
3293 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3294 Z39.50. But ISO/ILL was, however.
3296 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3297 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3299 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3300 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3302 --- 1.8.5 2002/02/03
3304 New YAZ client features: Command completion and new commands:
3305 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3306 Code provided by Jacob Poulsen.
3308 New call oid_trav, that visits all registered OIDs via callback.
3310 Function ZOOM_record_get now returns const char pointer rather than
3311 void pointer. It saves a lot of type casts.
3313 For YAZ client, command "auth" now allows you to set authentication
3314 in IdPass style. It is enabled when three tokens are given - order
3315 is user, group and password.
3317 Fix memory leaks in MARC record handling for ZOOM.
3319 New option for YAZ client, -k <kilobytes> that sets
3320 maximum record size. Similar to -k option for generic frontend
3321 server and yaz-ztest.
3323 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3325 Prefix query parser reports "fail" when bad attribute set is given.
3327 Fix in MARC decoder. Proximity logging. Fix for attribute set
3328 in scan handler for server. Patches by Shigeru Ishida.
3330 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3333 Configure option --with-openssl=<dir> now works when a directory is
3334 specified. Patch provided by Morten Bogeskov.
3336 New option for YAZ client, -u <auth>, that sets authentication.
3338 ZOOM fix: error information was sometimes "missing", since error
3339 was cleared/reset too when it shouldn't.
3341 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3343 --- 1.8.4 2002/01/04
3345 Scan for ZOOM API. New object ZOOM_scanset. New functions
3346 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3347 ZOOM_scanset_destroy.
3349 New ZOOM function, ZOOM_connection_last_event, that returns type
3350 of last event (such as "receive data", "send data", "apdu received",
3353 New ZOOM option, schema, that specifies schema for retrieval.
3355 New CCL feature. Qualifiers can be aliases for one or more
3356 other qualifiers (if more than one is given, OR is used).
3358 ZOOM uses named result sets if target supports it.
3360 Two new YAZ client commands: . (dot, which sources a script of YAZ
3361 client commands), and ! (to execute shell command.). Implemented
3364 Working on Debian packages.
3366 --- 1.8.3 2001/11/19
3368 YAZ client enables named result sets only if target supports it.
3370 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3372 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3373 with key="host" to get same result.
3375 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3376 Function Z3950_resultset_record(s) returns references to records
3377 "owned" by resultset. To become owner use Z3950_record_clone.
3379 Function z_ext_record handles Extended Services. Thanks to
3382 --- 1.8.2 2001/11/12
3384 CCL Parser fix: ignore token comma when dealing with and-lists.
3386 Documentation updates for COMSTACK.
3388 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3389 Changed prototype Z3950_records. For some functions, int parameters
3390 were changed to size_t.
3392 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3395 New MARC decode/display function, marc_display_exl, which properly rejects
3396 non-ISO2709 records. YAZ client uses it.
3398 --- 1.8.1 2001/10/29
3400 Fix bug: local attribute set wasn't set correctly in PQF strings.
3404 * Old Z39.50 codecs no longer supported.
3406 Added ZOOM C binding. See http://zoom.z3950.org/
3408 Renamed states for COMSTACKs to avoid confusion with events.
3410 Implemented cs_look and proper cs_rcvconnect.
3412 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3414 Configure detects POSIX threads on OpenBSD.
3416 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3417 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3419 When error is returned from present handler, non-surrogate diagnostic
3420 is returned in present response (and fetch handler is no longer called).
3422 * Minor adjustments to pquery parser (PQF). Token characters may be
3423 escaped by using backslash (C-style).
3425 PQF parser allows string attribute values to be specified. For @attr,
3426 non-numeric characters after the equal-sign are treated as strings
3427 (e.g. @attr 9=title).
3429 CCL trunction character may be defined (@truncation in file)
3431 * function zget_ExtendedServicesRequest sets waitAction to
3432 waitIfPossible (was wait).
3434 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3437 CCL operator names may be set in field definition files (CCL_bibset).
3438 See ccl/bib1 for an example.
3440 Fixes in ASN.1 compiler for C++ compatibility.
3442 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3443 and "op_or" to avoid conflict with C++.
3445 Fixed problem with GNU readline detection on Redhat 7.0.
3447 Added step-size for Scan backend handler.
3449 Fixed bug that made the frontend server crash when no attribute
3450 set was specified for scan.
3452 Front-end server automatically switches to original working directory
3453 when installed as an NT service. Previously -w had to be specified to
3456 Added extended attributes for retrieval module (data1), so that data1
3457 records carry d1_readXML/SGML attributes. d1_read also supports
3458 null-data rules ( <tag/>)
3460 On UNIX when POSIX threads are available, a separate library libyazthread
3461 is created. Programmers should link with that library and the yaz library
3462 when using threads. The reason for the split was that some applications
3463 on Linux, such as Apache, doesn't work well when using shared objects that
3466 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3467 (or any frontend server) in SSL mode by specifying ssl: followed by
3468 address. Only tested on UNIX.
3470 Added feature for CCL module. Virtual structure s=al or s=ol generates
3471 and-list and or-list respectively instead of phrase search.
3475 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3476 log_mask_str. This was done to avoid name conflicts with other libraries
3477 (such as other PHP extensions).
3479 Added raw OID member for preferred record syntax (request_format_raw)
3480 and returned record syntax (output_format_raw) for backend fetch method.
3482 Config file yaz-config now accepts options so that it returns specific
3483 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3485 Shared library support for UNIX using GNU libtool.
3487 * Modified backend interface. Request/Response struct's replaced by
3488 one read/write C struct. For example bend_fetchrequest and
3489 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3490 Every handler - even search has to be registered in bend_init
3491 handler. This means that the YAZ library no longer refers to
3492 external functions and it makes it possible to make the whole
3493 thing a single DLL/SO.
3495 Added Segment handler for backend server.
3497 Added Zmbol/Zebra administrative functions to YAZ client.
3499 Threaded frontend server on UNIX (when POSIX Threads are available).
3500 Starting the server with option -T enables multi-threading.
3504 Added configure option --enable-comp/disable-comp to control use
3505 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3506 located in sub directory asn.
3508 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3509 in ${exec_prefix}/bin along with the other programs yaz-client and
3512 GNU automake used to maintain makefiles.
3514 Added several OID's.
3516 Changed retrieval module so that we can load records with no abstract
3517 syntax defined. Tagpaths in these records are fully composed of string
3520 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3524 On UNIX, the generated makefile now supports a proper 'make install'.
3525 The prefix can be set via GNU configure to set the install location
3526 (default is /usr/local).
3528 * YAZ programs client and ztest were renamed to yaz-client and
3529 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3530 locations, such as /usr/bin,/usr/local/bin,etc.
3532 * YAZ Header files were moved from include to include/yaz. YAZ Header
3533 files are referred to as include <yaz/log.h> rather than <log.h>.
3534 The YAZ include path (-I ..) is therefore the same as before. Programmers
3535 should update their #include statements or use -Ipath/include/yaz
3536 instead. The main motivation for doing this change is that YAZ header files
3537 can be installed in "standard" locations /usr/include,/usr/local/include
3538 without introducing conflicts, since ALL YAZ header files are stored
3539 in subdirectory yaz (under /usr/include for example).
3541 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3542 rather than project/workspace files. We switched because project files
3543 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3546 Changed name of logging function, logf, to yaz_log, to prevent name
3547 clash with some math-log functions. The YAZ header log.h defines logf
3548 to yaz_log (#define) so there should be no incompatibilities by this
3551 Added bend_start/bend_stop handlers for server. These handler are
3552 called on start/stop of server. For windows they are called whenever
3553 a service is started/stopped.
3555 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3556 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3557 in util/yc.tcl. The auto-generated C code structures are, in a few
3558 cases, incompatible with the old decoders. There are differences in the
3559 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3560 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3561 The preprocessor variable ASN_COMPILED is defined when the compiled
3562 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3563 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3564 wish to use the old encoders/decoders you can specify --disable-yc
3567 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3568 version so that it supports both new - and old version of DB Update
3570 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3571 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3572 change. The name parameter can be set to 0 in which no name is specified
3573 for the construction. The macros odr_implicit and odr_explicit sets name
3574 parameter to zero for the construction involved. New macros
3575 odr_implicit_tag and odr_explicit_tag are similar to the others,
3576 except that a name parameter is added. For programmers' that don't use
3577 ODR they probably only need to change the call to z_APDU and z_External.
3579 Added access control facility by interfacing the TCP wrapper library.
3580 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3581 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3582 name of the daemon and enables the access control as specified in
3583 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3585 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3586 den Dool <H.M.vdnDool@kub.nl>.
3588 Added reference ID parameter to most functions in server API - refer
3589 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3591 Changed name of ccl library to libccl.a (was ccl.a).
3593 Fixed bug in decoder for Explain (Category TargetInfo).
3595 Added support for GNU readline in client. Thanks to Jacob Poulsen
3596 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3598 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3599 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3600 IMPLEMENTATION! This change was made to the development version before
3601 the ZIG decided to retract the amendment. If any users MUST be
3602 compatible with the original Update definition, PLEASE CONTACT US, and
3603 we will include a separate definition corresponding to the old Update
3604 ES. Note that because of the change to the ASN.1 of the
3605 TaskPackageRecordStructure we cannot define a single structure that
3606 will support both versions.
3608 * Added const modifier to buffer parameter for some ODR/BER encoding
3609 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3610 completeWAIS, odr_dumpBER.
3612 Fixed bug in client.c which caused a crash when a scanResponse didn't
3613 contain positionOfTerm.
3615 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3616 * will cause an error in a client if a non-YAZ target sends both a
3617 * list of Scan entries and non-surrogate diagnostics.
3619 Retrieval module enhancements. Tag sets may be typed in the reference
3620 to it. From the .abs-file the "tagset" directive takes a third optional
3621 integer type for the tag set referenced. From a .tag-file the "include"
3622 directive takes a third optional type as well. The old "type" directive
3623 in the tag set itself is still recognized but acts as the default type
3626 Backend interface change. Individual Scan terms returned from bend_scan
3627 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3628 in include/backend.h.
3630 Retrieval module enhancements. Multiple tag sets and attribute sets may
3631 be specified in abstract syntax specs. Revised the error/warning for
3632 logging messages reported by the retrieval module when reading the
3635 Object Identifier system (oid_..) changed. The API is backwards
3636 compatible but the oid-routines now allocates new OID's when needed.
3637 Raw OID's may be specified in oid_getvalbyname.
3639 YAZ now uses GNU configure to generate Makefile(s).
3641 * Minor changes in some of the member names of DeleteResultSetRequest and
3642 DeleteResultSetResponse. See include/proto.h.
3644 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3645 and added member 'languages' in TargetInfo (which was missing).
3647 Changed the way attribute sets are handled in the retrieval
3648 module. These are now cached, just like the abstract syntaxes
3651 Changed YAZ so that it links with compiled ASN.1.
3653 Added Explain-schema definitions and mapping routines. The following
3654 Explain categories have been implemented: AttributeDetails,
3655 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3657 Fixed minor bug in Windows version of Server Library.
3659 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3661 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3663 Added EXTERNAL: UNIverse Resource Report (non-standard).
3665 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3666 ENUMERATED and SET OF.
3668 * Added 'const' to some of the char pointer arguments for the
3669 functions, data1_read_node, data1_getelementbytagname,
3670 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3673 Fixed bug in data1_insert_taggeddata - the last_child member of
3674 parent wasn't initialised.
3676 * Changed data1_read_record and data1_read_node so that the supplied
3677 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3678 doesn't refer to any parts of the "SGML"-buffer.
3680 Fixed bug in server library (Windows version of statserv_remove).
3682 * Changed code so that it compiles as C++. The type definition
3683 of Odr_fun which is a member of Odr_arm was changed. The result is,
3684 that an explicit typecast is needed for the fun pointer when
3685 using Odr_arm - as in:
3686 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3688 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3690 Implemented the new structured date and time definition as approved
3691 by the ZIG. Added schemaId element to the specificTag in Espec-1
3692 (also approved at the last ZIG). Thanks to RVDM.
3694 Added some Object identifiers (RVDM).
3696 Changed the Update Extended Service (RVDM).
3698 Added command "refid" to client which specifies referenceId for
3699 the following requests.
3701 Implemented extended service handling for server. See ztest.c
3702 for an example as well as backend.h. New handlers are registerd
3703 in the Init handler.
3705 * Changed interface for sort in server.
3707 Added new members to statserv_options_block. It allows a server
3708 to read options from another source than just the command line. Thanks
3709 to Charles Woodfield.
3711 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3712 renamed to zboolean. Some C++ compilers complained about the name.
3714 Minor changes to gils.abs. Added index 's' (sort) on title
3715 and date/time-last-modified.
3717 --- 1.4pl2 1998/1/30
3719 Fixed bug in server library regarding inetd mode (-i). This bug
3720 was introduced by release 1.4.
3722 --- 1.4pl1 1998/1/29
3724 Added sort facility in client and backend server interface.
3726 Fixed problem with dependencies in Makefile(s).
3728 Fixed bugs for encoders/decoders of extended services and
3731 Implemented sub-tree feature for schemas. Sub-trees are
3732 referenced in *.abs-files. See explain.abs for an example
3733 of the use of this feature.
3735 Modified bib1.att; local attributes for ANY didn't include
3736 ANY itself (only affects use of the retrieval module).
3738 Fixed bug in plain SGML reader in function data1_read_node:
3739 tags with prefix "var" was incorrectly interpreted as variants.
3741 Added feature "sub-schemas" to enable references to - and definitions
3742 of - group of elements.
3744 * Removed member parent from type data1_element (in data1.h).
3746 Implemented function odr_nullval() that returns the value of
3749 * Removed member num_children from data1_node (in data1.h).
3751 Made NT service interface part of the server library. The
3752 function statserv_main uses the NT service when required and
3753 calls the statserv_start / statserv_close routines.
3755 Routine zget_SearchRequest and zget_PresentRequest fills
3756 resultSetName/Id member with "default" instead of "Default".
3758 Fixed memory leak in server. Request queue member wasn't freed.
3760 Fixed nmem_exit so that memory is freed.
3764 Revised the CCL parser utility to be thread safe.
3766 Added function, oid_ent_to_oid, to replace the function
3767 oid_getoidbyent, which is not thread safe.
3769 * Added nmem_init and nmem_exit to initialize and release
3770 NMEM resources. Function nmem_init should be called once in the
3771 initial thread before NMEM/ODR is used. statserv.c and client.c
3772 have been changed accordingly. The change was necessary to make
3773 NMEM thread safe. The NMEM memory pool is shared amongst threads
3774 in a process. Unix-based applications will still work fine without
3777 Added NT Services interface for the the Z39.50 (statserv) Server.
3778 Refer to the ztest.c source on the usage.
3780 Windows 95/NT port using MSVC5.0. Project files are included in the
3783 * Defined new 'global' handle for the retrieval (data1) system. The
3784 new handled, data1_handle, describes the state of the data1 system.
3785 This handle is passed as first argument to virtually all
3786 data1 related routines. The functions data1_create and data1_destroy
3787 creates and destroys a data1 handle respectively.
3789 Added ODR encode stream member to all backend request structures
3790 init, search, scan etc. This stream should be used to allocate all
3791 memory used for the response when thread safe operation is needed.
3793 Changed the comstack utility, cs_addstr, to be thread safe. The
3794 returned hostname string returned by the function is now part the
3797 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3798 function. The cs_straddr takes a COMSTACK handle as argument, so this
3799 function must be used after cs_create and before bind/connect.
3800 This function is thread safe.
3802 Moved test server to 'ztest' directory - generic server code still
3803 in 'server' directory.
3805 Made prefix query (pquery.c) utility thread safe.
3807 Added new function modifier YAZ_EXPORT to 'export' public DLL
3808 functions when using windows (see include/yconfig.h).
3810 Added definitions to the OID database (util/oid.c) (RVDM).
3812 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3814 Added call to ccl_rpn_delete in client program.
3816 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3817 release of RPN structure.
3819 Added support for C++, headers uses extern "C" for public definitions.
3820 With input from RVDM.
3822 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3823 Thanks to Ronald van der Meer (RVDM).
3825 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3827 Added support for private extensions to the OID database
3828 (oid_setprivateoids()). Thanks to RVDM.
3830 Added optional, physical ANY (key replication)
3832 Fixed null-reference problem in GRS-1 output filter.
3834 Proximity operator added to Prefix Query Format (PQF).
3836 In test client command "base" accepts multiple databases.
3838 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3842 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3844 Smallish bug-fixes in the new encoders/decoders (explain).
3846 Bug fixed in DeleteRequest.
3848 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3850 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3852 Added SOIF syntax (using private OID for now) to retrieval module and client.
3854 Added Update extended service.
3856 Added SearchResult-1 additional info structure.
3858 Added optional CCL (ISO8777) interpreter as separate module. Available
3861 --- 1.2 1996/6/10 (1st anniversary release)
3863 Added Summary record syntax. Lightly tested.
3865 Added OPAC record syntax. Untested.
3867 Added ResourceReport service encoders/decoders. Untested.
3869 Fixed bug in z_Unit - wrong tagging on unitSystem.
3871 Fixed bug in the DiagRecs decoder.
3873 Added options for max PDU size and session timeout to frontend-server.
3875 Added documentation of query-language parsers and other supporting utilities.
3877 [frontend-server] Added Attribute set to the bend_scanrequest API.
3879 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3880 surrogate diagnostics were generated.
3882 [retrieval] Allow multiple local values for attribute.
3884 [retrieval] Allow multiple attributes per element in .abs files. index type.
3886 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3888 --- 1.1pl2 1996/4/10
3890 Minor changes, mostly specific to Zebra's requirements (retrieval)
3894 Repaired bug in frontend server when running multiple listening
3895 endpoints in dynamic mode.
3897 z_External() now won't break if a known, ASN.1 value comes encapsulated
3898 in an octet-string. The value will pass through unmodified in an Odr_oct.
3900 Added a bit of code to the demo client to decode & display
3901 ASN.1-structured records represented in the octet-aligned branch of
3902 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3904 Added z_ext_getentbyref() to the ASN module. Doc updated.
3906 * Completed the SCAN definition in the ASN module. This may break SCAN
3907 code based on older YAZ-versions at compile-time. The fix is easy -
3910 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3911 under the SCAN definition. Remember to initialize this, server-people.
3913 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3914 that this does not extend to ODR and ASN.
3916 Comstack allows insertion of established socket (primarily for
3917 inetd-operation of servers). Doc updated.
3919 Front-end server can now start from the inetd in TCP mode. Doc
3922 --- 1.0pl4 1996/1/24
3926 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3927 the rank and record number.
3929 Adjustments to the frontend server.
3931 Fixed diagnostic BER dumper. It ignored the file argument.
3935 Various changes to retrieval module.
3937 Changed the union discriminators of the protocol files from enums to
3938 ints paired with #defines.
3940 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3943 *Changed operator in the RPN structure to 'roperator', again to avoid a
3946 Fixed problems in Explain decoders/encoders.
3948 --- 1.0pl2 1995/12/6
3950 Memory bug in log module fixed.
3952 --- 1.0pl1 1995/12/5
3954 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3956 Bug in Explain DatabaseInfo module fixed.
3958 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3962 The shift to v1.0 signals that we now consider the *core* functionality
3963 of YAZ reasonably stable (the core being more or less equivalent to
3964 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3965 tested (Explain not at all - though that will happen soonish).
3967 Minor changes to code to support Windows port.
3969 Various minor changes after we're getting to use GRS-1 & co. more.
3971 Added Espec-1 format.
3973 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3974 of the protocol and it cannot be selected when encoding (maps into 'string'
3975 when decoding). Needed to talk to some servers.
3977 Demo client can request simple element set names.
3979 Added Diagnostic Format encoders/decoders.
3981 Added simple Close handling to frontend server (no hooks for resource
3982 reporting yet), and demonstration client.
3984 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3986 --- 1.0b3 1995/08/24
3988 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3989 handled incorrectly when records were requested in the searchResponse. This
3990 will only affect you if you use the frontend-server.
3992 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3993 Test-client will ask for and print GRS1. Ztest will return dummy records
3996 Added Explain encoders/decoders to the service-level API. Untested.
3998 Added Extended Services: Item Order encoders and decoders to the Service-
3999 level API. Untested. We could use a recent copy of the pertinent bits
4000 of the ILL protocol to add those bits.
4002 Added diagnostic format 1 encoders/decoders to the service-level API.
4005 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4006 odr_cons.c, which causes a more correct output.
4008 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4009 was always set to 0 when no records were requested in the searchRequest.
4011 * Added better external-handling. This shouldn't harm old code that
4012 *encodes* externals. It can break code that looks for a
4013 'single-ASN1-type' representation, since those types that are known
4014 are now decoded immediately. Look at the SUTRS sample code in
4015 seshigh.c and client.c. Documentation updated.
4017 Handling of structured records in bend_fetchresponse. Length -1 marks
4018 structured record, type is deduced from format field.
4020 --- 1.0b2 1995/06/27
4021 Fairly quick maintenance release to add SUTRS support.
4023 Fixed handling of SUTRS records in the demonstration client.
4025 * Added format field to the bend_fetchrequest and bend_fetchresponce
4026 structures of the backend API (frontend server). When the record is
4027 returned, the value of the format field is mapped to an OID. The
4028 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4029 of the record. The special value VAL_NONE in the bend_request means
4030 that no specific format was requested by the client. Documentation
4031 updated accordingly. Test server (ztest) will return a fixed dummy
4032 SUTRS record if your client requests SUTRS.
4034 Documentation updated accordingly.
4036 You can now set external libraries and RANLIB support in the top-level
4040 First public release.
