1 Fixed bug #2709: TCP connect returns Invalid argument.
3 Fixed compilation for mingw.
5 Honor charset for raw records (ZOOM_record_get).
7 Fixed use of errno for threaded mode that was seen on Solaris 10.
9 Fixed argument passing with blanks in value for Windows Service.
11 Disable YAZ' own log rotate by default (no 1 GB limit).
12 The variable l_max_size which specifies the log file limit is set to 0
13 (DISABLED): This is due to the fact that YAZ is most often deployed using
14 logrotate. Also YAZ can not perform log rotate because of unsufficient
19 List supported encodings in man page for yaz-iconv.
21 Fixed missing SSL libs for --libs output
23 Re-established OID record syntax application-xml. Nobody should use it
24 but we don't want to change soname because of this symbol being absent.
28 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
30 Added member named_result_sets for init handler struct for the GFS. This
31 allows a server to disable named result sets.
33 Removed OID record syntax application-xml.
35 Added support for rule-based transliterator for ICU wrapper of YAZ.
37 Fixed bug #1902: yaz-icu XML output.
39 Make YAZ checks Emacs friendly.
41 BITSTRING value shows value. Bug #2346.
43 ISO2709 decoding: skip control characters from indicator data.
45 Omit sort key by default in yaz-icu's output.
47 Allow combined single char options (again) for YAZ' options function.
49 Utility yaz-marcdump got option to display YAZ version (-V).
51 Allow YAZ to use ICU 3.4.
53 Added new ICU test case which illustrates removal of diacritics.
57 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
61 For configure, using option --without-xml2 also disables Libxslt/Libexslt
64 Fixed bug #2352: yaz-marcdump crashes for certain record.
66 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
68 Added support for Danmarc2 to UTF-8 conversion.
70 Added support for ISO5426 to UTF-8 conversion.
72 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
73 implementation version.
75 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
79 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
80 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
82 ZOOM C now interprets databaseName option for ZOOM connection as path
85 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
87 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
89 Dummy Libxml2 types no longer defined in headers of YAZ'.
91 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
96 Various ODR chapter fixes.
98 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
100 Added missing source for Windows compilation, mutex.c.
102 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
104 For SRU connections in ZOOM all records up to "count" are now fetched.
106 Fixed crash in generic frontend server (and yaz-ztest) which occurred
107 in Windows due to bad error handling for Libxml2.
109 Added facility for sending arbitrary records (ASN.1 any) using
110 ZOOM C's Extended service update. Patch by Sam Reynolds.
112 New options for ZOOM C's connection, logapdu which makes ZOOM log
115 --- 3.0.34 2008/06/18
117 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
119 --- 3.0.32 2008/06/12
121 Fixed memory violation that could occur when decoding UTF-8. This bug
122 was only present in 3.0.30 of YAZ.
124 --- 3.0.30 2008/06/06
126 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
127 GNU TLS is used by default (if found).
129 yaz-ztest returns OPAC records if a client asks for OPAC.
131 Improved speed of MARC-8 encoding.
133 Added support for lossy and loss-less MARC-8 encoding.
135 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
137 Added new Windows Service wrapper (sc).
139 yaz-client's itemorder command may now send a file.
141 Fixed yaz-marcdump to allow the use of NS prefix for record element.
143 Added new function yaz_log_xml_errors.
145 Allow (but warn) unknown XML attributes in MARCXML parsing.
147 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
149 The UTF-8 to MARC-8 conversion now uses a different set of characters
150 for Greek symbols. Bug #2120.
152 --- 3.0.26 2008/02/21
154 Added yaz_daemon (daemon.h).
156 Fixed bug #2068: pkg-config trouble
158 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
160 --- 3.0.24 2008/01/28
162 Document --with-xml2 option.
164 Added OPAC XML XSD (etc/opacxml.xsd).
166 Allow glob mask for name attribute in retrieval element for the
167 generic frontend server's retrieval facility.
169 Changed yaz_poll_poll to return yaz_poll_except for all returned events
170 except POLLIN/POLLOUT.
172 Fixed error handling in cs_listen. Bug #2037.
174 --- 3.0.22 2008/01/20
176 Fixed version in yaz/yaz-version.h.
178 Fixed bug #2027: Crash when closing connection.
180 Changed configure so that ICU support is only enabled if only ICU
181 and Libxml2 is available (because the ICU chain is XML based).
183 --- 3.0.20 2008/01/15
185 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
186 is built. Only this DLL depends on the ICU runtime.
188 yaz-ziffy is no longer part of YAZ. It is distributed separately by
189 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
191 Changed license of CCL module to 'Revised BSD'. After consultation with
192 remaining members of the original EUROPAGATE consortium, we are re-issuing
193 the CCL module without a separate license. The software was developed by
194 Index Data as part of a research project. The special license was included
195 to help feed usage information back to the project consortium to support
196 project evaluation. At this time, the project consortium has long-since
197 disbanded, and the majority of the original principals have retired. At the
198 same time, we have significantly modified the software during the following
199 years, to the point where very practically no original code remains. To
200 simplify re-use of the software, we have contacted those members of the
201 consortium who could be reached, and agreed to re-issue the module as a
202 proper part of the YAZ package.
204 Tcl scripts uses /usr/bin/tclsh as preferred shell.
206 CQL closer to being version 1.2 compliant. CQL also allows free-form
207 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
210 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
211 bug could make Extended services handling crash in the ZOOM layer. This
212 bug was only present in YAZ 3.0.18.
214 --- 3.0.18 2007/12/19
216 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
219 yaz-marcdump reads and writes collection wrapped records.
221 Handle OPAC for record conversion module.
223 Fixes for ICU wrapper.
225 Allow ICU libs to be controlled with --with-icu .
227 --- 3.0.16 2007/11/12
229 Added yaz_poll which is a wrapper for select/poll. When poll is available
230 and non-buggy, it is used, by yaz_poll . This allows more than 1024
231 sockets to be in use.
233 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
234 functionality through an XML based configuration (ICU chain). This system
235 is useful for search facilities such as Pazpar2 and Zebra that needs to
236 perform tokenization of indexed material. The ICU code in a separate
237 library libyaz3_icu.a.
239 Added HTTP tunnel facility for COMSTACK, bug #1752.
240 This is a facility that allows a Web proxy, such as squid, to tunnel
241 Z39.50 traffic. This facility is "transparent" to must applications
242 using YAZ. It's enabled by using pseudo transport connect: followed by
243 the proxy address, followed by command, then follwed by he regular
244 "virtual" addresss. For example,
245 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
247 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
249 --- 3.0.14 2007/09/21
251 Fixed bad memory reference in ZOOM_record - cuased by member not being
252 initialized. This was a problem only in YAZ 3.0.12.
254 Fixed bug in conversion from MARC to XML: Non-XML characters in control
255 fields were not removed.
257 Changed the way C code is generated from codetables.xml. Made a MARC-8
258 conversion trie for each characterSet section rather than codeTable.
259 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
260 of codetables.xml from Larry Dixson, LOC. Bug #1464.
262 --- 3.0.12 2007/09/12
264 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
265 from ZOOM_record_error).
267 ZOOM C function ZOOM_record_get returns record schema for type="schema".
269 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
271 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
273 Better SRW-to-Bib-1 diagnostic mapping.
275 ZOOM C and yaz-client announces SRU version 1.2 by default.
277 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
280 Fixed in yaz_sru_decode to allow other version than 1.1.
282 --- 3.0.10 2007/08/22
284 Added support for SRU scan for ZOOM.
286 Added support for the use of the older versions or Extended Service
287 Update in ZOOM. To faciliate this, an option "updateVersion" may be
288 set to the version , 1=first, 2=second, 3=third. The third version is
289 what ZOOM C has used so far. And that, obviously, is the default.
291 Added support for CCL queries in Z39.50 queries sent to the GFS (and
292 therefore in Zebra and in SimpleServer-based applications). The new
293 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
294 qualifier file used to transform incoming CCL queries into Type-1 RPN,
295 which is passed into the back-end search callback function.
297 Added support for HTTP Basic authentication in clients: the SRU/W
298 codec encodes the username/password elements of the PDU structure
299 appropriately, and these may be set using the "user" and "password"
300 options in ZOOM-C applications (the same options that are used for
301 Z39.50 authentication).
305 Fixed bug #1208: SSL appears to be broken in ZOOM.
307 Fixed bug #1206: Libxml2 include path weirdness.
309 Added oid_name_to_dotstring.
311 Allow elementSetName to be specified for ZOOM C record update.
313 Allow waitAction to be specified for ZOOM C based for Extended Services.
315 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
316 syntax OID. Bug introduced in YAZ 3 series.
318 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
322 Fixed bug #1157: yaz-client does not read .yazclientrc from current
323 directory. yaz-client now reads commands from file given by option -f
324 if specified; then tries to read .yazclientrc in current directory.
325 Failing that, it reads .yazclientrc from user's home directory.
327 Added support for correlationInfo Note and ID for Record Update via
330 Added yaz-client command querycharset which specifies character set for
331 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
332 (termListAndStartPoint).
334 Charset ISO5428:1984 is an alias for ISO5428-1984.
336 Implemented a way to perform scan in a result set using Z39.50. This
337 is achieved by attaching the result set name in the characterInfo
338 (type InternationalString) of OtherInformation in the Scan Request PDU.
339 The result set is identified in the otherinformation by the new OID:
340 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
341 This allows for scan in result set and faceted search . Zebra did some
342 of this in the APT term using attribute type 8 and value being result
343 set. Using the OtherInformation approach for this is cleaner and easier
344 to work with in proxies and the like. This facility can be used in
345 yaz-client using new command setscan which takes a result set as first
346 argument, start position (APT) as second.
348 Changed decoding of SRU XML packed records to deal with servers that
349 have recordData with XML data with multiple root nodes. Also make
350 comparison for recordPacking case insensitive. Again, one server
351 returns "XML" where others return "xml".
353 For SRU responses allow Content-Type application/xml as well as text/xml.
357 Fixed bug in character set conversion of BER strings. Bug introduced
362 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
364 For OID class, use oid_class consistently.
366 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
369 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
370 character set for bibliographic information interchange". By Giannis Kosmas.
372 Added documentation on new OID API.
376 Changes to generic frontend server interface: added new member
377 'query_charset' for bend_initrequest structure. A backend init handler
378 should set this member to its native character set for query terms.
379 When defined, the frontend server logic will announce this character set
380 to a client if the negotiationModel bit is set by the client. All server
381 implementors are encouraged to specify this. If a backend server does not
382 specify this a warning is issued using yaz_log(YLOG_WARN,..).
384 Added CCL utility to remove terms (stop words) from resulting RPN
385 tree. This is handled by functions with prefix ccl_stop_words_ .
387 New ZOOM C option, "rpnCharset", which allows client-side conversion of
388 terms in RPN queries.
390 Clean-up the CCL API. Moved some internal structures from ccl.h to
391 private header cclp.h. Changed ccl_parser_create so that a Bibset must
392 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
393 This is replaced by ccl_parser_find_str which takes a string instead.
395 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
396 libyaz.la is the core of YAZ except the generic frontend server and
397 does not depend on POSIX threads anymore. libyaz_server.la is the
398 generic frontend server facilities and uses POSIX thread functionality
399 if available. The libyaz.la no longer depends on POSIX threads because
400 the number of global structures is limited. NMEM no longer re-uses blocks
401 between threads ; it simply free's memory immediately but allocates in
402 "large" chunks as usual. We don't expect any performance penalties
403 because of this. The yaz_log system is still using a global log_level so
404 caution must be taken when modifying it with yaz_log_init_.. +
405 yaz_log_mask_str. This, however, should not cause any trouble because
406 these functions are called during initialization of application code
407 anyway. `yaz-config --libs server` returns libs for server applications;
408 `yaz-config --libs` returns libs for non-server applications.
410 New OID database - with public definitions in oid_db.h. Removed old OID
411 database including the head oid.h and definitions such as enum oid_value
412 and struct oident. The new OID database uses the same string names as
413 before but the 'protocol' is gone. There are now only two representations
414 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
415 converts from string to OID; functions with prefix yaz_oid_to_string
416 converts the other way.
418 Change to emit_term() in CQL-to-PQF query translation: when a term has
419 the /regexp relation modifier, do not process it for leading and
420 trailing "^" and "*", which have quite different meanings in regular
423 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
424 write handlers no longer carries a 'last' parameter. This will make
425 yaz_iconv flush "less" characters. A flush is performed by call to
426 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
428 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
429 removed, because function yaz_query_to_wrbuf does the same.
431 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
432 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
434 Deprecated MARC utility functions removed.
436 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
439 Branch split: YAZ_2_1_55_branch
441 --- 2.1.54 2007/03/16
443 Fix to ZOOM-C so that transparent reconnection is properly handled on
444 connections that are in asynchronous mode.
446 Fixed compilation on OpenBSD 4.0.
448 Large strings in GRS-1 records are now properly displayed in yaz-client.
450 Added character conversion support for "advancegreek"; based on patch from
453 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
454 sequence is met. Before the error was not set so it would be unknown.
456 Adjust yaz-marcdump MARC reader so that it skips until record separator
459 --- 2.1.52 2007/03/07
461 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
462 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
463 fd_set structure used as a bitmask for the FDs to be selected on.
465 Using ACX_PTHREAD macro to check for POSIX threads.
467 Fixed have-vsnprintf check.
469 --- 2.1.50 2007/02/23
471 Fixes for configure on BSD. Bug #900.
473 Added snprintf/vsnprintf wrappers for systems that don't have
474 limits (heavens forbid).
476 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
477 created before all previous tasks were completed and removed from the
478 task queue, the new task could be removed by a mistake.
480 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
482 Implemented pass-through CQL-to-PQF conversions. Bug #861.
484 Fixed bug #832: Problem with MARC/charset in yaz-client.
486 Fixed bug #668: save command line history for yaz-client.
488 Fixed bug #830: pkg-config support.
490 --- 2.1.48 2007/01/23
492 Extended ZOOM result set options with two options that may be read by
493 a client: resultSetStatus and presentStatus with values as specified for
495 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
497 Fixed bug #827: Using SSL fails on Debian etch.
499 Fixed bug #826: Weird looking chars for set of MARC records.
501 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
502 that is treated as an ItemOrder with itemRequest being an XML document
503 external. The value of "doc" is the content.
505 Extended the GFS search facility. New member of bend_search_rr
506 'estimated_hit_count' signals that hits is known to be an estmate
507 (higher or lower than real hit count). New member 'partial_resultset'
508 signals that the search was partial (hit count is lower or equal than
509 real hit count). For Z39.50, the information is stored in resultSetStatus
510 member of SearchResponse APDU. For SRU, the information is signalled
511 via SRU diagnostic 59: "Result set created with valid partial results
514 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
516 --- 2.1.46 2007/01/13
518 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
520 Added ZOOM_connection_peek_event.
522 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
523 the following new functions:
524 ZOOM_event_nonblock, ZOOM_connection_process,
525 ZOOM_connection_get_{socket,mask,timeout},
526 ZOOM_connection_fire_event_{timeout,socket}.
527 The existing blocking event handler, ZOOM_event, is a wrapper for the
528 + blocking ZOOM_event_sys_{poll,select}.
530 Implemented function ccl_xml_config which parses XML version of CCL
531 configuration (bug #798).
533 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
535 Added timings utility (yaz/timing.h)
537 --- 2.1.44 2007/01/03
539 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
542 Fixed bug #779: Rotation of apdu.log fails.
544 Fixed for character set conversions:
545 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
546 Honor G1 set in MARC-8 decoding.
548 --- 2.1.42 2006/12/17
550 Fixed bug #775: char conversion does not handle Alternative UTF-8
553 Implemented function yaz_marc_read_line which parses MARC line format
554 records. There is a wealth of formats out there. So far, this function
555 reads line records produced by yaz_marc_write_line.
557 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
558 more generic and easier to remember(!) options: -i format and -o format
559 which specifies input format and output format respectively - where
560 format is one of "marc", "marcxml", "line", "marcxchange".
562 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
563 does not print anything except warnings for records.
565 For yaz-marcdump, added support for MARC split into files (-s) with a given
568 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
569 spec, at http://www.loc.gov/standards/sru/record-update/
570 This has changed the binary layout of the following structs:
571 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
572 bend_update_rr . Patch by Ko van der Sloot.
574 Added GFS utility function bend_assoc_is_alive which returns 1 if
575 association is still alive (client is connected); 0 otherwise (client
576 closed connection). This allows busy servers to stop working for
579 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
580 been a separate piece of software. This version of ziffy has been modified
581 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
583 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
585 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
586 Client code may now interrogate options such as "init_opt_sort" to
587 find out whether the server claims to support various options.
589 --- 2.1.40 2006/11/27
591 Added utilities yaz_{set,get}_esn to set/get element set name from
594 Removed the build of libyazthread.la. The libyaz.so is the threaded version
595 of YAZ and has been so since YAZ 2.1.10.
597 Implemented ZOOM_record_error which returns error information for
598 record (surrogate diagnostic).
600 --- 2.1.38 2006/10/31
602 Updates for SRU Update by Ko van der Sloot:
603 1. Changed name from "operation" to "action"
604 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
605 versions in the code, marked as 'backward compatible'.
606 3. Added diagnostics for SRU Update.
608 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
610 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
612 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
614 For GFS, fixed problem with SRU diagnostic 'First record position out of
615 range' being issued for 0 hits.
617 zoomtst10 part of Windows Build.
619 --- 2.1.36 2006/10/13
621 Implemented yaz_filepath_comp which splits a path into file path
622 components (required by Zebra 2.0.3+).
624 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
625 BSD inspired license until now so this should not have any real impact on
626 anybody. See http://www.opensource.org/licenses/bsd-license.php
628 Fixed bug #687: Missing log lines.
630 Fixed bug #678: CQL to PQF translation does not preserve double-quote
633 Fixed bug #689: SRU diagnostics to be added.
635 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
636 whether a connection is idle (no more work do do).
638 --- 2.1.34 2006/10/04
640 Change type of optval from long to int for invocation of setsockopt with
641 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
643 Added support for specifying the max log file size for the Generic
644 Frontend Server. The size is given with option -r.
646 --- 2.1.32 2006/09/21
648 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
650 --- 2.1.30 2006/09/17
652 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
655 Fixed bug in Generic Frontend Server that could cause a server to stop
656 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
658 For the generic frontend server, the maximum record size is used as maximum
659 size of incoming packages (SRU + Z39.50). The value until was previously
660 only used in Z39.50 Init negotiation and, later, in a session controlled
661 sizes of records returned. This is controlled using -k option. It can be
662 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
664 --- 2.1.28 2006/09/04
666 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
669 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
671 New option for yaz-marcdump -lpos=value which allows setting a portion
672 of MARC header to a certain value.
674 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
676 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
677 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
679 --- 2.1.26 2006/08/15
681 Fixed problem with SRU mode type (soap, get, post) for yaz-client
684 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
686 --- 2.1.24 2006/08/08
688 Fixed MARC ISO2709 encoding routines to deal with character set
691 Minor changes to GFS logging. Database included in search request log
694 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
695 cached/multiple records.
697 Shared libraries are built by default on Unix+configure.
699 Changed cql2pqf transformation to use a different evaluation order. The
700 new order is: always, relation, structure, position, truncation, index
701 and relationModifier. Old order was: always, relation, relationModifier,
702 structure, index, position, truncation. Note that the the latter ones
703 override former ones for identical attributes.. The new scheme means that
704 it is possible to override any existing attribute with a relationModifier.
705 And also that it is possible to override everything for the index rule
706 (except the ones listed in relationModifier). No order is perfect but this
707 one, we believe, covers more real cases.. The "always" should have been
708 called "default", since the attributes there can be overridden with all
711 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
712 compilation phase, but also for yaz-config --cflags output. This allows
713 us to have public headers with Libxml2 stuff in them . It should also,
714 eventually, make Libxml2 checks redundant in packages using YAZ, such
717 --- 2.1.22 2006/06/15
719 Changed SRU update structure bend_update_rr so that SRU diagnostics are
720 stored in uri, message and details.. Previously diagnostics were stored
721 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
722 compatibility.. but he's probably the only one affected, so.
724 Added support for CCL, compiled on the client side, in ZOOM-C. This
725 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
726 input; the resulting query objects can be used for for searching with
727 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
729 YAZ' configure searches for OpenSSL by default.
731 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
732 SL_CTX_use_certificate_file. See
733 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
734 for more info. Thanks to Ko van der Sloot.
736 --- 2.1.20 2006/06/02
738 Bug #600: SRU GET, POST support for yaz-client. Introduced
739 command 'sru' which selects method SOAP/GET/POST.
741 Allow missingValueAction to be specified for the sortspec string -
742 function yaz_sort_spec. By default, the missing value action is null.
743 Use ! to specify "abort". Use = followed by stringvalue to specify default
746 Ensured that Present-handler (if defined) is called in GFS before any call to
747 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
748 searchRetrieve requests.
750 Documentation for YAZ is now based on the Docbook XML/XSLT using
751 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
752 is no longer depending on jade/openjade or docbook-to-man scripts.
753 PDF is no longer part of the distribution - but can optionally be
754 made using DSSSL/jadetex or FOP.
756 Added retrieval handling support in Generic Frontend Server to support
757 conversion between MARC/XML as well as XSLTtransforms. See
758 etc/yazgfs.xml for an example.
760 Added Authentication support to Generic Frontend Server in SRU
761 mode. Authentication using HTTP Basic is supported, as is the use
762 of 'x-username' and 'x-password' parameters in the request itself.
764 Added support for a new character set MARC8s identical to MARC8 except
765 that it converts combined characters to single Unicode characters in the
766 Latin-1 range (when possible).
768 --- 2.1.18 2006/04/24
770 ASN.1 compiler 0.4: generates brief Doxygen file header for
771 generated .h/.c files.
773 Utility yaz_iconv now supports conversion to MARC-8.
775 New facilities for the MARC module. The reading - and writing of
776 content are separate methods for the yaz_marc_t handle. The following
777 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
778 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
779 format). Write functions have prefix yaz_marc_write_.. The existing
780 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
781 available. Removed support for OAI-MARC and simplexml (not the
782 simplexml from PHP5).
784 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
785 to be returned for this connection.
787 --- 2.1.16 2006/03/31
789 Allow multiple languages and charsets to be specified with
790 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
791 negcharset iso-8859-1,utf-8
793 Translation of proximity nodes from CQL into PQF now works.
795 Moved to automake 1.8, 1.9.
797 Added function yaz_log_set_handler which allows a log handler to be
798 installed. This handler will be called for all log messages. Output
799 to file is also produced; but that can be disabled by passing NULL
800 fname to yaz_log_init_file.
802 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
804 For SRW (including GFS), accept application/soap+xml as content-type
807 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
808 produces NO stylesheet reference even if a default stylesheet is specified
811 --- 2.1.14 2006/03/14
813 Updated Windows package to include yazd.dll + yazd.lib for the
814 Development component.
816 If the environment variable YAZ_LOG is set, then it is used as a
817 string indicating the default level of logging to use if not
818 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
819 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
820 used as before. So, for example, to omit warnings from YAZ logging,
823 cql_transform() now map structure and other attributes before indexes,
824 so that index-specific structures and other attributes can override
825 defaults. So now a combination of mapping specifications such as:
827 index.dc.date = 1=date-modified 4=5
828 does the right thing.
830 cql_transform() now also respects the "always" mapping specification,
831 which establishes an initial set of attributes to be used for all
832 terms except where overridden by more specific attributes associated
833 with the index, relation or modifier.
835 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
836 which mode to use; one of "post", "get" or "soap" (SRW, default).
838 Fixes for yaz_iconv routines: changed trie-based character set conversions
839 to use only non-negative values for bit fields due to Sun's C compiler not
840 supporting negative values.
842 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
843 sequences where not read correctly. Fix by Rustam Usmanov.
845 Updated win/makefile to use options, settings which makes things
846 compile with VS C 2005.
848 --- 2.1.12 2006/02/01
850 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
852 In ZOOM socket code, use select instead of poll on MacOSX.
854 ZOOM-C now support client-side compilation of CQL into RPN that is
855 sent to the server, enabling CQL to be used against all Z39.50
856 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
857 ZOOM_query object, and submit it using ZOOM_connection_search().
858 The CQL-to-RPN translation uses a configuration file, the name of
859 which must be specified in the Connection's "cqlfile" option.
861 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
862 function, which takes as its start-term parameter a ZOOM_query object
863 (which may have had either CQL or RPN set into it).
866 --- 2.1.10 2005/11/29
868 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
869 GFS to support this as well. Backend handler, bend_srw_update, does the
870 update work. Code contributed by Ko van der Sloot.
872 Allow retrieval of Search Result-1 information in ZOOM by the use of
873 options that are attached to a result set. ZOOM documentation updated
876 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
877 UTF-8 conversion. Patch by Raj Patel.
879 Added option -m to GFS to control formatting of timestamps in log file.
881 Added 'exit' as synonym for 'quit' in yaz-client
883 Added support for specifying SRW resultSetId + resultSetIdleTime in a
884 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
885 for the new members. Patch by Ko van der Sloot.
887 Added support for SRU POST. It is supported for content-type
888 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
890 Do not build the separate Multi-threaded (MT) library libyazthread.la.
891 Instead make the library libyaz.la multi-threaded. Threading as a whole
892 can still be disabled by configure option --disable-threads. Previosly,
893 with older GLIBCs there were problems with MT libs under Apache. This
894 has now been fixed a long time ago.
896 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
899 CQL module modified to be case insensitive for relations/indexes/operations.
901 Fixed bug in CQL transform code: incorrect value relationModifieder
904 Added 'show all' command for yaz-client which retrieves all results
907 Added new yaz-client, xmles, which takes a (private) OID and
908 a document to be sent as an extended service request.
910 Describe new yaz-client commands wait_response and set_auto_wait.
912 Increase TCP/IP listener backlog from 3 (which I am guessing was
913 copied from the SunOS manual entry way back when) so SOMAXCONN, so
914 that the socket will queue as many incoming connections as it's able
915 to handle ongoing connections. In other words, it will never now
916 refuse a connection that it would be able to handle merely because
917 it's not got around to accepting() enough of the pending connections
918 yet. This is the behaviour anyway under Linux, where the listen()
919 argument is ignored; but not under BSD and on systems such as
920 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
921 YAZ-based servers should now be uniform across operating systems in
924 yaz-marcdump uses 64-bit file access on some systems. This is enabled
925 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
926 This allows yaz-marcdump to read large MARC batches (>2 GB).
928 Modified all YAZ source files - except the source which is auto-generated
929 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
932 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
933 corresponding to the existing *_setl() function. These allow option
934 values containing arbitrary valuues.
936 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
937 ZOOM_resultset_sort() in new applications. Its behaviour is identical
938 except that it returns an indicator of whether or not the sort
939 criterion was accepted (0 for OK, -1 for invalid).
943 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
944 MARC output rather than returning "new" buffer.
946 yaz-client warns about unknown init options.
948 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
952 Added support for SRW sort in Generic Frontend Server. Patch
953 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
954 sortKeys - or NULL if none is provided.
956 Fixed bug #307: It was impossible to specify indefinite/no timeout
957 for ZOOM_event. Special timeout value -1 now means indefinite timeout
960 Added support for multiple languages and charsets to be specified in
961 ZOOM. Each charset/language is separated by a blank. If negotiation is
962 in effect in init-response, Option
963 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
964 Code based on patch by Vasiliy Osadchuk.
966 Fixed bug #306: infinite recursion that occurred when calling
967 yaz_log_level_init as the first call (before other log level or
970 Fixed bug in scan handling in front end server: if preferred-Position-In-
971 Response was non-present, a NULL pointer referece was performed.
975 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
976 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
977 now defined for all those error codes. So instead of putting 109 in
978 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
979 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
981 Modified the yaz-marcdump utility to skip garbage bytes between MARC
984 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
986 Program yaz-client now exits and produces an error message if multiple
987 Z39.50 servers are specified on the command line (none or one allowed
990 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
995 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
997 Fixed bug #272: Preserve spacing for CCL terms.
1001 Added support for virtual hosts and multiple backend servers for
1002 the YAZ frontend server. The configution is XML based and
1003 support specificition of CQL to RPN mappings and explain information.
1004 See section "Virtual Hosts" in the YAZ manual.
1006 Extended OPAC display utility. OPAC display utility renders
1007 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1008 to supplement yaz_marc_decode_wrbuf.
1010 Fixed a bug in MARC decoder that could caused it to crash for some
1011 invalid MARC records. More diagnostics and warnings where added in
1012 XML output (warnings, etc are stored in comments).
1014 --- 2.0.34 2005/02/08
1016 Fixes for UNIX domain sockets. Bug #261.
1018 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1020 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1021 Added yaz_marc_subfield_str which defines subfield lead string which is
1022 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1023 yaz_marc_endline_str which defines end of fields string used in
1024 YAZ_MARC_LINE format. Default string is newline.
1026 Experimental support for MarcXChange. This format can be produced
1027 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1028 http://www.bs.dk/standards/MarcXchange.xsd
1030 Added yaz-client commands scansize that sets maximum number of
1031 entries to be returned by scan.
1033 --- 2.0.32 2005/01/11
1035 Added support for SRW scan in yaz-client and Generic Frontend Server.
1037 * Added whereInList member to SRW Scan Term.
1039 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1041 Fixed NMEM system to return aligned blocks on the smallest boundaries
1042 that are suitably aligned for all possible types on the particular
1043 architecture YAZ is being built for.
1045 --- 2.0.30 2005/01/04
1047 Fixed numerious warnings that was issued with newer versions of GCC.
1049 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1050 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1053 Make YAZ Generic Frontend Server slightly faster.
1055 Enhance (and reduce) logging for Generic Frontend Server.
1057 Revert YAZ log system so that it flushes every write operation
1058 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1060 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1061 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1062 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1063 will effectively disable old definitions.
1065 --- 2.0.28 2004/11/09
1067 Added yaz_log_time_format which specifies log format using
1070 Added yaz_log_module_level which returns mask for a module. Value
1071 is non-zero mask a if module is enabled; zero if disabled.
1073 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1074 in include/yaz/cql.h.
1076 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1078 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1080 Fixed bug #172: RPM builds does not enable SSL.
1082 Doxyfile.in part of dist. Doxyfile generated by configure.
1084 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1085 are given and the corresponding component does not exist.
1087 Extend CCL documentation in YAZ reference. Describe r=r.
1089 --- 2.0.26 2004/10/01
1091 Fixed MARC->MARCXML conversion to properly deal with
1092 fields, subfields, indicators having non-ASCII characters.
1094 Fixed MARC->MARCXML conversion so that ASCII control characters
1095 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1098 Added YAZ GFS support for conversion from Z39.50 surrogate
1099 diagnostics to SRW surrogate diagnostics.
1101 Bug fix: YAZ GFS did not return schema in explainResponse.
1103 --- 2.0.25 2004/09/30
1105 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1106 now converts recordSchema to elementSetName as well as schema URI.
1108 Fixed bug in COMSTACK that prevented HTTP request packages from being
1111 --- 2.0.24 2004/09/29
1113 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1114 does not require white-space before and after the dash in a range, e.g.
1115 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1118 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1119 due to new GCC removing "redundant" code.
1121 Added yaz-client commands scanpos and scanstep that sets preferred
1122 position and step-size for scan.
1124 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1126 Added CCL utility ccl_qual_buf which parses one or more CCL
1127 spec lines in a buffer.
1129 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1130 of name and value - ignoring empty lines and comments.
1132 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1134 Added odr_get_element_path which returns current element path for an
1135 ODR handle. This utility is useful in error handling or user-defined
1138 Added ODR_PRINT utility odr_set_stream which is is a more generic
1139 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1140 to a write function and pointer to close function. The close function - if
1141 non-NULL - will be called during odr_destroy.
1143 Fixed bug in CCL parser where truncation char was not removed from
1144 right side when truncation=both was in effect.
1146 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1149 --- 2.0.23 2004/08/11
1151 Fix buffer overrun in CQL parser when dealing with proximity (%).
1153 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1154 to UTF-8/UCS conversion is now only based on codetables.xml.
1156 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1158 --- 2.0.22 2004/08/06
1160 Add support for more "commit changes" in ZOOM (uses Extended Services).
1162 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1165 Yet another small fix for configure of SSL.
1167 --- 2.0.21 2004/05/14
1169 Fix SSL libs for configure when --with-openssl=DIR is given.
1171 --- 2.0.20 2004/05/10
1173 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1175 SSL comstack now uses yaz.pem certificate file on server side
1176 by default. Certificate filename can be configured by calling
1177 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1179 Fix bug regarding multiple calls to ZOOM_connection_connect.
1181 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1183 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1184 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1186 ZOOM now allows inspection of X509 peer certificate for verification.
1187 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1189 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1190 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1191 as "modular" but it simplifies things.
1193 Added cs_get_peer_certificate to that returns peer X509 PEM.
1195 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1196 NULL if SSL is unavailable.
1198 Documentation about MARC decoding tools.
1200 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1202 --- 2.0.19 2004/03/30
1204 Rename CHANGELOG to NEWS to follow GNU style packing.
1206 Fix bug with missing initialization of member in init_diagnostics.
1207 This bug affects threaded version of GFS server.
1209 --- 2.0.18 2004/03/20
1211 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1214 Ensure zlib.dll is packed with Windows install.
1216 --- 2.0.17 2004/03/17
1218 Fix encoding of xsd:string to use text instead of CDATA.
1220 Fix endless loop in CQL parser with unbalanced ".
1222 Use a more compact way to store MARC-8 conversion tables.
1224 --- 2.0.16 2004/03/16 Debian only
1226 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1229 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1234 --- 2.0.15 2004/03/01
1236 Another fix for decoding of XML packed records.
1238 --- 2.0.14 2004/02/25
1240 Fixes for Chunked encoding. White space not ignored after length spec.
1242 Update NS and use default NS for SRW diagnostic elements.
1244 --- 2.0.13 2004/02/23
1246 Implement ZOOM_resultset_cache_reset which resets record cache.
1248 Implement ZOOM_resultset_sort which sorts a result set.
1250 Implement chunked HTTP transfer.
1252 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1254 --- 2.0.12 2004/02/16
1256 Added member 'schema' to bend_explain_rr structure so that backend
1257 can specify explain record identifier. Defaults to Zeerex 2.0.
1259 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1261 --- 2.0.11 2004/02/16
1263 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1266 Added init command for yaz-client which sends "extra" init request.
1268 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1269 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1271 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1273 Make ZOOM error code for "invalid query".
1275 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1277 --- 2.0.10 2004/02/05
1279 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1282 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1284 Added option -p <file> to make Generic Frontend Server to write PID file.
1286 Added option -D to put Generic Frontend Server in background on its own.
1288 Make ZOOM C recognize option "password". If unset, "pass" is used
1289 (for backwards compatibility).
1291 Fixed a bug in Generic Frontend Server that could make it crash if a
1292 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1295 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1296 Must be issued before open, in order to be in effect.
1298 --- 2.0.9-6 2004/01/12 Debian/Windows
1300 Make the SRU server more picky WRT unknown params, etc.
1302 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1304 New YAZ client command, options, that sets Z39.50 options.
1306 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1307 options from a string of tokens (one token for each option bit).
1309 Update SRW diagnostic code messages.
1311 --- 2.0.9-5 2004/01/07 Debian/Windows
1313 Handle user defined stylesheet for SRW/SRU.
1315 --- 2.0.9-4 2004/01/06 Debian/Windows
1317 Fix bug in decoding of Content-Length.
1319 --- 2.0.9-3 2004/01/06 Debian/Windows
1321 Fix a bug with decoding of XML packed records.
1323 --- 2.0.9-2 2004/01/05 Debian only
1325 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1327 Fix bug in SRW/SRU diagnostics decoding.
1329 --- 2.0.9 2004/01/05
1331 Fixed bug in Generic Frontend Server which could drop records exceeding
1332 preferred message size. Reported and fixed by Irina Dijour.
1334 Fixed calculation of package size for structured records in Generic
1335 Frontend Server. Reported and fixed by Irina Dijour.
1337 Fixed namespace for SRW/SRU diagnostics.
1339 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1341 --- 2.0.8 2003/12/22
1343 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1344 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1347 CQL changes to reflect recent changes to the specification:
1348 * Documentation talks about context sets instead of index sets.
1349 * Documentation talks about indexes instead of qualifiers.
1350 * The CQL-to-PQF transformer's configuration file now uses
1351 "index.set.name = <attributes>" instead of the old form
1352 "qualifier.set.name = <attributes>". (Both forms are still
1353 understood but the latter is deprecated.)
1354 * CQL terms with no explicit index specified are now interpreted as
1355 cql.serverChoice instead of srw.serverChoice (which of course
1356 behaves exactly the same.)
1358 --- 2.0.7 2003/12/16
1360 MARC conversion can now generate ISO2709 output in another
1361 character set. yaz-marcdump uses this facility if you invoke it
1364 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1365 functions from there can be used from C++.
1367 --- 2.0.6 2003/12/04
1369 Frontend server now transfers memory from decoded packages to stream
1372 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1373 references to show up.
1375 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1376 the ZOOM Abstract API. The older names for the same options are still
1377 also supported for the benefit of old applications.
1379 ZOOM-C supports "implementationId" and "implementationVersion" options
1380 to go along with "implementationName". These allow the user code to
1381 specify identification strings to be sent to servers.
1382 Add OID for the new ExtLite attribute set.
1384 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1385 as requested/supplid by Ere Maijala <ere@atp.fi>
1387 For generic frontend server, reverse the order of
1388 "toolkit-supplied / application-supplied" strings sent as implementationId,
1389 Name and Version. Also, remove the spaces around the slash. This brings
1390 the GFS in line with the behaviour of ZOOM-C on the client side.
1392 Add function ZOOM_scanset_display_term.
1394 yaz-client shows scan displayTerm if present.
1396 Utility yaz-iconv is now installed by default along with the man page
1399 Extend configure check for OpenSSL to use pkg-config where available (such
1402 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1403 server to specify uid/gid/mask for socket using the format
1404 unix:[user=uid,][group=gid,][umask=mask,]file=path
1405 If file= is omitted the existing format is assumed, e.g.
1407 in which case the mask is 0666 (rw for everybody).
1409 Major restructure of YAZ source. All source in libyaz is in src directory.
1410 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1411 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1413 Added man page for utility yaz-marcdump (used to be called marcdump).
1414 yaz-marcdump is installed by 'make install'.
1416 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1417 of incoming package failed.
1419 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1421 Change prototype of odr_perror: add const to message string.
1423 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1425 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1426 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1427 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1428 DNS lookup. There should not be any compatibility problems with this
1429 assuming that blocking=1 or 0 is used.
1431 Fix bad reference in UNIX comstack in function cs_addrstr.
1433 Fix for compilation on AIX.
1435 The generic front-end server (server/seshigh.c) now supports returning
1436 Init diagnostics to the client in User-information-field, in
1437 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1440 --- 2.0.4 2003/09/04
1442 Allow any CQL relation (not just all,any,exact,scr).
1444 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1445 that features the same UI.
1447 Implemented command update0 in YAZ client which is equivalent to
1448 update but uses old of Ext Update ASN.1.
1450 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1451 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1452 Previously no OID was used for this info.
1454 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1455 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1456 returns 'malformed search term' otherwise.
1458 SortResponse member resultCount now set to NULL in sort handler of
1461 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1464 Add three new utility functions for translating OIDs between various
1465 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1466 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1467 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1468 char *oid_to_dotstring(const int *oid, char *oidbuf);
1469 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1471 Reverted modifications for ES Update definition for z_IU0Update
1472 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1473 is back to YAZ 2.0.2.
1475 String value attributes for CCL parser.
1477 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1478 which their FirstSearch server returns in Init responses, sometimes
1479 carrying useful diagnostic information when Init fails. This has the
1480 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1481 "z39.50/oclcui.asn", where its definition is somewhat different from
1482 what OCLC document on their web-site, as required to interoperate with
1485 Support for anonymous authentication in yaz-client. Use the command
1488 * Fix the OID of the Index Data-local "admin" Extended Service from
1489 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1490 the 1000, which indicates a locally-defined OID, was a mistake.
1492 --- 2.0.3 2003/06/20
1494 Fix CCL directive @case handling so that it affects string match for
1495 both CCL keywords and qualifiers.
1497 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1498 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1499 Decoder has been updated with ASN.1 changes as listed in
1500 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1501 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1502 z_IUUpdate, remains unchanged.
1504 ZOOM_record_get may now return a record in a specific character set.
1505 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1506 "from" is the character set of record as returned by target. "to" is
1507 the character set to be returned. If omitted, "to" is UTF-8.
1509 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1511 New ODR utility, odr_getelement, which returns name of element for
1512 which encoding/decoding failed.
1514 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1515 in cases where a required element was omitted.
1517 Bug fix: some MARC8 sequences were not converted.
1519 New ZOOM option "step" which specifies number of records to be
1520 retrieved in one chunk. Used in conjunction with "start" and "count".
1522 SRW support for yaz-client. Use scheme http: to use it, e.g.
1525 yaz-client no longer does (un)intelligent character set conversions
1526 by default. Can be enabled with charset and marc_charset commands.
1528 xmalloc trace fix for 64-bit systems such as DEC alpha.
1530 Solaris 2.6 compile fix.
1532 New function, cql_strerror() translates SRW error codes, as returned
1533 by cql_transform_error(), into human-readable English strings. Used
1534 in yaz-client diagnostics when appropriate.
1536 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1537 converts it into a type-1 query which is sent to the server. This
1538 makes CQL available for use with all Z-servers, as opposed to the tiny
1539 minority that can handle CQL queries themselves.
1541 --- 2.0.2 2003/04/28
1543 New Debian package layout similar to the Redhat Package layout.
1545 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1546 and search result respectively.
1548 --- 2.0.1 2003/04/25
1550 Redhat package is now several packages: libyaz (runtime libraries),
1551 libyaz-devel (development and documentation, and yaz (utility programs).
1552 Package spec file by Morten Bogeskov.
1554 New member 'schema' in struct bend_fetch_rr which the name of requested
1555 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1556 handler MAY set this to reflect the schema of the returned record.
1558 New member 'display_term' in struct scan_entry. GFS now sets member entries
1559 and allocates scan entries to be filled by user scan handler. In previous
1560 version, entries member was allocated by the scan handler. That still works,
1561 but the GFS will ignore member display_term - assuming it was NOT set by
1562 the handler. The fact that the GFS now allocates the entries both allows
1563 for new members and makes a scan handler easier to write.
1565 Fix CQL lex buffer overflow.
1567 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1568 SRU default recordPacking is string.
1570 SRU protocol support for frontend server.
1572 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1574 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1576 Added scan for the ZOOM shell (zoomsh).
1580 * String Identifers for Schemas (Amendment 5).
1581 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1582 Old definition for schema
1583 Odr_oid *schema; /* OPT */
1588 Z_InternationalString *uri;
1589 #define Z_Schema_oid 1
1590 #define Z_Schema_uri 2
1593 * resultCount parameter to Sort Response (Amendment 1).
1594 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1596 Support for SRW 1.0 over HTTP. This is an optional feature and
1597 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1600 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1601 on the same port. SRW SearchRetrieveRequests are mapped
1602 to bend_init,bend_search,bend_fetch,bend_close.
1604 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1606 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1607 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1609 ZOOM connections are SRW based if schem http is used for hostname
1610 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1611 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1613 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1614 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1615 distance=n, order=true/false, relation=le, prox unit=word. If
1616 n is omitted, distance 1 is used.
1618 Fixed problem with C compiler include path in wrong order.
1620 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1621 on Solaris. Patch from Ko van der Sloot.
1623 New MARC decode API. All new functions operate on a yaz_marc_t
1624 handle. The most important new functions are: yaz_marc_create,
1625 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1626 decode and destroy respectively. Decoder can produce formats
1627 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1628 include/yaz/marcdisp.h.
1630 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1631 to UTF-8, UCS-32, wchar_t or Latin-1.
1633 * Prototypes for yaz_iconv_-functions moved to separate header
1634 include/yaz/yaz-iconv.h.
1636 Make a few private functions 'static' in unix.c. This prevents
1637 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1639 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1640 are set when Init Response is received.
1642 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1643 but returns diagnostic set as well.
1645 New function yaz_strerror which is a portable wrapper for
1646 strerror/strerror_r/GetLastMessage.
1648 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1649 is returned for MARC. If type is "oai", then OAI MARC is returned.
1651 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1654 --- 1.9.2 2002/11/26
1656 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1658 Fix bad race conditions on SIGTERM and terminate gracefully in
1661 Move retrieval (data1) module to Zebra since nobody seems to be
1664 Add GRS-1 render for ZOOM using same format as yaz-client.
1666 --- 1.9.1 2002/10/05
1668 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1670 Fix broken ESpec handling in data1 module.
1672 SGML reader parses comments and makes them part of the data1 tree.
1674 Added several type casts so that YAZ compiles as C++ code.
1676 ZOOM didn't handle PDU encoding failures properly.
1678 Added more Bib-1 diagnostics (approved extensions).
1680 GNU configure: better check for iconv.
1682 More portable use of accept, getpeername. Check for socklen_t. Use
1683 int/size_t if socklen_t is not defined.
1687 PQF parser rejects bad queries - including those with extra
1688 characters in them. PQF parser used to silently ignore that.
1689 Cleaner API for PQF added, which allows you to get detailed
1690 error information for bad queries (see yaz/pquery.h).
1692 Fixed bug in ZOOM_record_get for type "database".
1694 Implemented mini iconv library supporting conversions between
1695 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1697 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1699 --- 1.8.9 2002/08/20
1701 Fixed ZOOM C record cache so that preferredRecordSyntax and
1702 elementSetName is used to check for already fetched records.
1704 --- 1.8.8 2002/08/02
1706 Added three members in bend_initrequest structure to facilitate
1707 character set negotiation.
1709 Fixed a bug in frontend server that could cause indefinite
1710 loops under rare conditions.
1712 Revised character set utilities (charneg.h) so that encoding
1713 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1715 For PQF, directive @term <type> sets term type for Scan/Search.
1716 Here <type> is general, string, numeric, null. The term type
1717 is inherited - just like @attr.
1719 New call odr_set_charset that sets character set conversion for
1720 international-strings on a ODR stream. Prototype is:
1721 int odr_set_charset(ODR o, const char *to, const char *from);
1722 The InternationalString is still represented as C string in YAZ
1723 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1724 won't). On the protocol level, you can use any encoding.
1726 Support for UNIX sockets in ZOOM.
1728 Solaris recv sometimes returns errno == ENOENT. It is treated as
1729 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1731 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1732 both client and server. Code by Morten Bogeskov.
1734 --- 1.8.7 2002/05/22
1736 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1737 that they can be used directly from Visual Basic. You must recompile
1738 your windows APP if you're using ZOOM.
1740 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1741 Commands "lang" and "charset" sets language and character set respectively.
1742 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1743 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1745 Attributes from multiple CCL fields may be OR'ed rather than merged
1746 using directive "@field or". Fields are still merged by default -
1747 equivalent to "@field merge".
1749 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1752 Fixed bug in zget for parameter ExtendedServicesResponse.
1756 --- 1.8.6 2002/03/25
1758 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1760 Client displays USR.1:SearchResult-1 (hits per term).
1762 Additional Search Info for search in Generic Frontend Server.
1764 Fixed CCL parsing of "field=s".
1766 WIN32 installer - using the excellent NSIS software from nullsoft.
1768 Fixed CCL parsing of "field = - <number>".
1770 Added function yaz_marc_decode that decodes MARC for line mode
1771 display or XML (similar to that used by JZKit).
1773 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1774 Z39.50. But ISO/ILL was, however.
1776 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1777 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1779 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1780 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1782 --- 1.8.5 2002/02/03
1784 New YAZ client features: Command completion and new commands:
1785 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1786 Code provided by Jacob Poulsen.
1788 New call oid_trav, that visits all registered OIDs via callback.
1790 Function ZOOM_record_get now returns const char pointer rather than
1791 void pointer. It saves a lot of type casts.
1793 For YAZ client, command "auth" now allows you to set authentication
1794 in IdPass style. It is enabled when three tokens are given - order
1795 is user, group and password.
1797 Fix memory leaks in MARC record handling for ZOOM.
1799 New option for YAZ client, -k <kilobytes> that sets
1800 maximum record size. Similar to -k option for generic frontend
1801 server and yaz-ztest.
1803 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1805 Prefix query parser reports "fail" when bad attribute set is given.
1807 Fix in MARC decoder. Proximity logging. Fix for attribute set
1808 in scan handler for server. Patches by Shigeru Ishida.
1810 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1813 Configure option --with-openssl=<dir> now works when a directory is
1814 specified. Patch provided by Morten Bogeskov.
1816 New option for YAZ client, -u <auth>, that sets authentication.
1818 ZOOM fix: error information was sometimes "missing", since error
1819 was cleared/reset too when it shouldn't.
1821 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1823 --- 1.8.4 2002/01/04
1825 Scan for ZOOM API. New object ZOOM_scanset. New functions
1826 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1827 ZOOM_scanset_destroy.
1829 New ZOOM function, ZOOM_connection_last_event, that returns type
1830 of last event (such as "receive data", "send data", "apdu received",
1833 New ZOOM option, schema, that specifies schema for retrieval.
1835 New CCL feature. Qualifiers can be aliases for one or more
1836 other qualifiers (if more than one is given, OR is used).
1838 ZOOM uses named result sets if target supports it.
1840 Two new YAZ client commands: . (dot, which sources a script of YAZ
1841 client commands), and ! (to execute shell command.). Implemented
1844 Working on Debian packages.
1846 --- 1.8.3 2001/11/19
1848 YAZ client enables named result sets only if target supports it.
1850 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1852 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1853 with key="host" to get same result.
1855 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1856 Function Z3950_resultset_record(s) returns references to records
1857 "owned" by resultset. To become owner use Z3950_record_clone.
1859 Function z_ext_record handles Extended Services. Thanks to
1862 --- 1.8.2 2001/11/12
1864 CCL Parser fix: ignore token comma when dealing with and-lists.
1866 Documentation updates for COMSTACK.
1868 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1869 Changed prototype Z3950_records. For some functions, int parameters
1870 were changed to size_t.
1872 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1875 New MARC decode/display function, marc_display_exl, which properly rejects
1876 non-ISO2709 records. YAZ client uses it.
1878 --- 1.8.1 2001/10/29
1880 Fix bug: local attribute set wasn't set correctly in PQF strings.
1884 * Old Z39.50 codecs no longer supported.
1886 Added ZOOM C binding. See http://zoom.z3950.org/
1888 Renamed states for COMSTACKs to avoid confusion with events.
1890 Implemented cs_look and proper cs_rcvconnect.
1892 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1894 Configure detects POSIX threads on OpenBSD.
1896 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1897 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1899 When error is returned from present handler, non-surrogate diagnostic
1900 is returned in present response (and fetch handler is no longer called).
1902 * Minor adjustments to pquery parser (PQF). Token characters may be
1903 escaped by using backslash (C-style).
1905 PQF parser allows string attribute values to be specified. For @attr,
1906 non-numeric characters after the equal-sign are treated as strings
1907 (e.g. @attr 9=title).
1909 CCL trunction character may be defined (@truncation in file)
1911 * function zget_ExtendedServicesRequest sets waitAction to
1912 waitIfPossible (was wait).
1914 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1917 CCL operator names may be set in field definition files (CCL_bibset).
1918 See ccl/bib1 for an example.
1920 Fixes in ASN.1 compiler for C++ compatibility.
1922 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1923 and "op_or" to avoid conflict with C++.
1925 Fixed problem with GNU readline detection on Redhat 7.0.
1927 Added step-size for Scan backend handler.
1929 Fixed bug that made the frontend server crash when no attribute
1930 set was specified for scan.
1932 Front-end server automatically switches to original working directory
1933 when installed as an NT service. Previously -w had to be specified to
1936 Added extended attributes for retrieval module (data1), so that data1
1937 records carry d1_readXML/SGML attributes. d1_read also supports
1938 null-data rules ( <tag/>)
1940 On UNIX when POSIX threads are available, a separate library libyazthread
1941 is created. Programmers should link with that library and the yaz library
1942 when using threads. The reason for the split was that some applications
1943 on Linux, such as Apache, doesn't work well when using shared objects that
1946 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1947 (or any frontend server) in SSL mode by specifying ssl: followed by
1948 address. Only tested on UNIX.
1950 Added feature for CCL module. Virtual structure s=al or s=ol generates
1951 and-list and or-list respectively instead of phrase search.
1955 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1956 log_mask_str. This was done to avoid name conflicts with other libraries
1957 (such as other PHP extensions).
1959 Added raw OID member for preferred record syntax (request_format_raw)
1960 and returned record syntax (output_format_raw) for backend fetch method.
1962 Config file yaz-config now accepts options so that it returns specific
1963 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1965 Shared library support for UNIX using GNU libtool.
1967 * Modified backend interface. Request/Response struct's replaced by
1968 one read/write C struct. For example bend_fetchrequest and
1969 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1970 Every handler - even search has to be registered in bend_init
1971 handler. This means that the YAZ library no longer refers to
1972 external functions and it makes it possible to make the whole
1973 thing a single DLL/SO.
1975 Added Segment handler for backend server.
1977 Added Zmbol/Zebra administrative functions to YAZ client.
1979 Threaded frontend server on UNIX (when POSIX Threads are available).
1980 Starting the server with option -T enables multi-threading.
1984 Added configure option --enable-comp/disable-comp to control use
1985 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1986 located in sub directory asn.
1988 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1989 in ${exec_prefix}/bin along with the other programs yaz-client and
1992 GNU automake used to maintain makefiles.
1994 Added several OID's.
1996 Changed retrieval module so that we can load records with no abstract
1997 syntax defined. Tagpaths in these records are fully composed of string
2000 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2004 On UNIX, the generated makefile now supports a proper 'make install'.
2005 The prefix can be set via GNU configure to set the install location
2006 (default is /usr/local).
2008 * YAZ programs client and ztest were renamed to yaz-client and
2009 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2010 locations, such as /usr/bin,/usr/local/bin,etc.
2012 * YAZ Header files were moved from include to include/yaz. YAZ Header
2013 files are referred to as include <yaz/log.h> rather than <log.h>.
2014 The YAZ include path (-I ..) is therefore the same as before. Programmers
2015 should update their #include statements or use -Ipath/include/yaz
2016 instead. The main motivation for doing this change is that YAZ header files
2017 can be installed in "standard" locations /usr/include,/usr/local/include
2018 without introducing conflicts, since ALL YAZ header files are stored
2019 in subdirectory yaz (under /usr/include for example).
2021 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2022 rather than project/workspace files. We switched because project files
2023 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2026 Changed name of logging function, logf, to yaz_log, to prevent name
2027 clash with some math-log functions. The YAZ header log.h defines logf
2028 to yaz_log (#define) so there should be no incompatibilities by this
2031 Added bend_start/bend_stop handlers for server. These handler are
2032 called on start/stop of server. For windows they are called whenever
2033 a service is started/stopped.
2035 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2036 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2037 in util/yc.tcl. The auto-generated C code structures are, in a few
2038 cases, incompatible with the old decoders. There are differences in the
2039 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2040 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2041 The preprocessor variable ASN_COMPILED is defined when the compiled
2042 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2043 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2044 wish to use the old encoders/decoders you can specify --disable-yc
2047 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2048 version so that it supports both new - and old version of DB Update
2050 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2051 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2052 change. The name parameter can be set to 0 in which no name is specified
2053 for the construction. The macros odr_implicit and odr_explicit sets name
2054 parameter to zero for the construction involved. New macros
2055 odr_implicit_tag and odr_explicit_tag are similar to the others,
2056 except that a name parameter is added. For programmers' that don't use
2057 ODR they probably only need to change the call to z_APDU and z_External.
2059 Added access control facility by interfacing the TCP wrapper library.
2060 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2061 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2062 name of the daemon and enables the access control as specified in
2063 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2065 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2066 den Dool <H.M.vdnDool@kub.nl>.
2068 Added reference ID parameter to most functions in server API - refer
2069 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2071 Changed name of ccl library to libccl.a (was ccl.a).
2073 Fixed bug in decoder for Explain (Category TargetInfo).
2075 Added support for GNU readline in client. Thanks to Jacob Poulsen
2076 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2078 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2079 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2080 IMPLEMENTATION! This change was made to the development version before
2081 the ZIG decided to retract the amendment. If any users MUST be
2082 compatible with the original Update definition, PLEASE CONTACT US, and
2083 we will include a separate definition corresponding to the old Update
2084 ES. Note that because of the change to the ASN.1 of the
2085 TaskPackageRecordStructure we cannot define a single structure that
2086 will support both versions.
2088 * Added const modifier to buffer parameter for some ODR/BER encoding
2089 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2090 completeWAIS, odr_dumpBER.
2092 Fixed bug in client.c which caused a crash when a scanResponse didn't
2093 contain positionOfTerm.
2095 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2096 * will cause an error in a client if a non-YAZ target sends both a
2097 * list of Scan entries and non-surrogate diagnostics.
2099 Retrieval module enhancements. Tag sets may be typed in the reference
2100 to it. From the .abs-file the "tagset" directive takes a third optional
2101 integer type for the tag set referenced. From a .tag-file the "include"
2102 directive takes a third optional type as well. The old "type" directive
2103 in the tag set itself is still recognized but acts as the default type
2106 Backend interface change. Individual Scan terms returned from bend_scan
2107 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2108 in include/backend.h.
2110 Retrieval module enhancements. Multiple tag sets and attribute sets may
2111 be specified in abstract syntax specs. Revised the error/warning for
2112 logging messages reported by the retrieval module when reading the
2115 Object Identifier system (oid_..) changed. The API is backwards
2116 compatible but the oid-routines now allocates new OID's when needed.
2117 Raw OID's may be specified in oid_getvalbyname.
2119 YAZ now uses GNU configure to generate Makefile(s).
2121 * Minor changes in some of the member names of DeleteResultSetRequest and
2122 DeleteResultSetResponse. See include/proto.h.
2124 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2125 and added member 'languages' in TargetInfo (which was missing).
2127 Changed the way attribute sets are handled in the retrieval
2128 module. These are now cached, just like the abstract syntaxes
2131 Changed YAZ so that it links with compiled ASN.1.
2133 Added Explain-schema definitions and mapping routines. The following
2134 Explain categories have been implemented: AttributeDetails,
2135 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2137 Fixed minor bug in Windows version of Server Library.
2139 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2141 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2143 Added EXTERNAL: UNIverse Resource Report (non-standard).
2145 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2146 ENUMERATED and SET OF.
2148 * Added 'const' to some of the char pointer arguments for the
2149 functions, data1_read_node, data1_getelementbytagname,
2150 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2153 Fixed bug in data1_insert_taggeddata - the last_child member of
2154 parent wasn't initialised.
2156 * Changed data1_read_record and data1_read_node so that the supplied
2157 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2158 doesn't refer to any parts of the "SGML"-buffer.
2160 Fixed bug in server library (Windows version of statserv_remove).
2162 * Changed code so that it compiles as C++. The type definition
2163 of Odr_fun which is a member of Odr_arm was changed. The result is,
2164 that an explicit typecast is needed for the fun pointer when
2165 using Odr_arm - as in:
2166 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2168 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2170 Implemented the new structured date and time definition as approved
2171 by the ZIG. Added schemaId element to the specificTag in Espec-1
2172 (also approved at the last ZIG). Thanks to RVDM.
2174 Added some Object identifiers (RVDM).
2176 Changed the Update Extended Service (RVDM).
2178 Added command "refid" to client which specifies referenceId for
2179 the following requests.
2181 Implemented extended service handling for server. See ztest.c
2182 for an example as well as backend.h. New handlers are registerd
2183 in the Init handler.
2185 * Changed interface for sort in server.
2187 Added new members to statserv_options_block. It allows a server
2188 to read options from another source than just the command line. Thanks
2189 to Charles Woodfield.
2191 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2192 renamed to zboolean. Some C++ compilers complained about the name.
2194 Minor changes to gils.abs. Added index 's' (sort) on title
2195 and date/time-last-modified.
2197 --- 1.4pl2 1998/1/30
2199 Fixed bug in server library regarding inetd mode (-i). This bug
2200 was introduced by release 1.4.
2202 --- 1.4pl1 1998/1/29
2204 Added sort facility in client and backend server interface.
2206 Fixed problem with dependencies in Makefile(s).
2208 Fixed bugs for encoders/decoders of extended services and
2211 Implemented sub-tree feature for schemas. Sub-trees are
2212 referenced in *.abs-files. See explain.abs for an example
2213 of the use of this feature.
2215 Modified bib1.att; local attributes for ANY didn't include
2216 ANY itself (only affects use of the retrieval module).
2218 Fixed bug in plain SGML reader in function data1_read_node:
2219 tags with prefix "var" was incorrectly interpreted as variants.
2221 Added feature "sub-schemas" to enable references to - and definitions
2222 of - group of elements.
2224 * Removed member parent from type data1_element (in data1.h).
2226 Implemented function odr_nullval() that returns the value of
2229 * Removed member num_children from data1_node (in data1.h).
2231 Made NT service interface part of the server library. The
2232 function statserv_main uses the NT service when required and
2233 calls the statserv_start / statserv_close routines.
2235 Routine zget_SearchRequest and zget_PresentRequest fills
2236 resultSetName/Id member with "default" instead of "Default".
2238 Fixed memory leak in server. Request queue member wasn't freed.
2240 Fixed nmem_exit so that memory is freed.
2244 Revised the CCL parser utility to be thread safe.
2246 Added function, oid_ent_to_oid, to replace the function
2247 oid_getoidbyent, which is not thread safe.
2249 * Added nmem_init and nmem_exit to initialize and release
2250 NMEM resources. Function nmem_init should be called once in the
2251 initial thread before NMEM/ODR is used. statserv.c and client.c
2252 have been changed accordingly. The change was necessary to make
2253 NMEM thread safe. The NMEM memory pool is shared amongst threads
2254 in a process. Unix-based applications will still work fine without
2257 Added NT Services interface for the the Z39.50 (statserv) Server.
2258 Refer to the ztest.c source on the usage.
2260 Windows 95/NT port using MSVC5.0. Project files are included in the
2263 * Defined new 'global' handle for the retrieval (data1) system. The
2264 new handled, data1_handle, describes the state of the data1 system.
2265 This handle is passed as first argument to virtually all
2266 data1 related routines. The functions data1_create and data1_destroy
2267 creates and destroys a data1 handle respectively.
2269 Added ODR encode stream member to all backend request structures
2270 init, search, scan etc. This stream should be used to allocate all
2271 memory used for the response when thread safe operation is needed.
2273 Changed the comstack utility, cs_addstr, to be thread safe. The
2274 returned hostname string returned by the function is now part the
2277 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2278 function. The cs_straddr takes a COMSTACK handle as argument, so this
2279 function must be used after cs_create and before bind/connect.
2280 This function is thread safe.
2282 Moved test server to 'ztest' directory - generic server code still
2283 in 'server' directory.
2285 Made prefix query (pquery.c) utility thread safe.
2287 Added new function modifier YAZ_EXPORT to 'export' public DLL
2288 functions when using windows (see include/yconfig.h).
2290 Added definitions to the OID database (util/oid.c) (RVDM).
2292 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2294 Added call to ccl_rpn_delete in client program.
2296 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2297 release of RPN structure.
2299 Added support for C++, headers uses extern "C" for public definitions.
2300 With input from RVDM.
2302 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2303 Thanks to Ronald van der Meer (RVDM).
2305 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2307 Added support for private extensions to the OID database
2308 (oid_setprivateoids()). Thanks to RVDM.
2310 Added optional, physical ANY (key replication)
2312 Fixed null-reference problem in GRS-1 output filter.
2314 Proximity operator added to Prefix Query Format (PQF).
2316 In test client command "base" accepts multiple databases.
2318 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2322 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2324 Smallish bug-fixes in the new encoders/decoders (explain).
2326 Bug fixed in DeleteRequest.
2328 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2330 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2332 Added SOIF syntax (using private OID for now) to retrieval module and client.
2334 Added Update extended service.
2336 Added SearchResult-1 additional info structure.
2338 Added optional CCL (ISO8777) interpreter as separate module. Available
2341 --- 1.2 1996/6/10 (1st anniversary release)
2343 Added Summary record syntax. Lightly tested.
2345 Added OPAC record syntax. Untested.
2347 Added ResourceReport service encoders/decoders. Untested.
2349 Fixed bug in z_Unit - wrong tagging on unitSystem.
2351 Fixed bug in the DiagRecs decoder.
2353 Added options for max PDU size and session timeout to frontend-server.
2355 Added documentation of query-language parsers and other supporting utilities.
2357 [frontend-server] Added Attribute set to the bend_scanrequest API.
2359 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2360 surrogate diagnostics were generated.
2362 [retrieval] Allow multiple local values for attribute.
2364 [retrieval] Allow multiple attributes per element in .abs files. index type.
2366 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2368 --- 1.1pl2 1996/4/10
2370 Minor changes, mostly specific to Zebra's requirements (retrieval)
2374 Repaired bug in frontend server when running multiple listening
2375 endpoints in dynamic mode.
2377 z_External() now won't break if a known, ASN.1 value comes encapsulated
2378 in an octet-string. The value will pass through unmodified in an Odr_oct.
2380 Added a bit of code to the demo client to decode & display
2381 ASN.1-structured records represented in the octet-aligned branch of
2382 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2384 Added z_ext_getentbyref() to the ASN module. Doc updated.
2386 * Completed the SCAN definition in the ASN module. This may break SCAN
2387 code based on older YAZ-versions at compile-time. The fix is easy -
2390 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2391 under the SCAN definition. Remember to initialize this, server-people.
2393 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2394 that this does not extend to ODR and ASN.
2396 Comstack allows insertion of established socket (primarily for
2397 inetd-operation of servers). Doc updated.
2399 Front-end server can now start from the inetd in TCP mode. Doc
2402 --- 1.0pl4 1996/1/24
2406 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2407 the rank and record number.
2409 Adjustments to the frontend server.
2411 Fixed diagnostic BER dumper. It ignored the file argument.
2415 Various changes to retrieval module.
2417 Changed the union discriminators of the protocol files from enums to
2418 ints paired with #defines.
2420 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2423 *Changed operator in the RPN structure to 'roperator', again to avoid a
2426 Fixed problems in Explain decoders/encoders.
2428 --- 1.0pl2 1995/12/6
2430 Memory bug in log module fixed.
2432 --- 1.0pl1 1995/12/5
2434 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2436 Bug in Explain DatabaseInfo module fixed.
2438 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2442 The shift to v1.0 signals that we now consider the *core* functionality
2443 of YAZ reasonably stable (the core being more or less equivalent to
2444 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2445 tested (Explain not at all - though that will happen soonish).
2447 Minor changes to code to support Windows port.
2449 Various minor changes after we're getting to use GRS-1 & co. more.
2451 Added Espec-1 format.
2453 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2454 of the protocol and it cannot be selected when encoding (maps into 'string'
2455 when decoding). Needed to talk to some servers.
2457 Demo client can request simple element set names.
2459 Added Diagnostic Format encoders/decoders.
2461 Added simple Close handling to frontend server (no hooks for resource
2462 reporting yet), and demonstration client.
2464 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2466 --- 1.0b3 1995/08/24
2468 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2469 handled incorrectly when records were requested in the searchResponse. This
2470 will only affect you if you use the frontend-server.
2472 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2473 Test-client will ask for and print GRS1. Ztest will return dummy records
2476 Added Explain encoders/decoders to the service-level API. Untested.
2478 Added Extended Services: Item Order encoders and decoders to the Service-
2479 level API. Untested. We could use a recent copy of the pertinent bits
2480 of the ILL protocol to add those bits.
2482 Added diagnostic format 1 encoders/decoders to the service-level API.
2485 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2486 odr_cons.c, which causes a more correct output.
2488 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2489 was always set to 0 when no records were requested in the searchRequest.
2491 * Added better external-handling. This shouldn't harm old code that
2492 *encodes* externals. It can break code that looks for a
2493 'single-ASN1-type' representation, since those types that are known
2494 are now decoded immediately. Look at the SUTRS sample code in
2495 seshigh.c and client.c. Documentation updated.
2497 Handling of structured records in bend_fetchresponse. Length -1 marks
2498 structured record, type is deduced from format field.
2500 --- 1.0b2 1995/06/27
2501 Fairly quick maintenance release to add SUTRS support.
2503 Fixed handling of SUTRS records in the demonstration client.
2505 * Added format field to the bend_fetchrequest and bend_fetchresponce
2506 structures of the backend API (frontend server). When the record is
2507 returned, the value of the format field is mapped to an OID. The
2508 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2509 of the record. The special value VAL_NONE in the bend_request means
2510 that no specific format was requested by the client. Documentation
2511 updated accordingly. Test server (ztest) will return a fixed dummy
2512 SUTRS record if your client requests SUTRS.
2514 Documentation updated accordingly.
2516 You can now set external libraries and RANLIB support in the top-level
2520 First public release.
