3 Fixed bug #2709: TCP connect returns Invalid argument.
5 Fixed compilation for mingw.
7 Honor charset for raw records (ZOOM_record_get).
9 Fixed use of errno for threaded mode that was seen on Solaris 10.
11 Fixed argument passing with blanks in value for Windows Service.
13 Disable YAZ' own log rotate by default (no 1 GB limit).
14 The variable l_max_size which specifies the log file limit is set to 0
15 (DISABLED): This is due to the fact that YAZ is most often deployed using
16 logrotate. Also YAZ can not perform log rotate because of unsufficient
21 List supported encodings in man page for yaz-iconv.
23 Fixed missing SSL libs for --libs output
25 Re-established OID record syntax application-xml. Nobody should use it
26 but we don't want to change soname because of this symbol being absent.
30 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
32 Added member named_result_sets for init handler struct for the GFS. This
33 allows a server to disable named result sets.
35 Removed OID record syntax application-xml.
37 Added support for rule-based transliterator for ICU wrapper of YAZ.
39 Fixed bug #1902: yaz-icu XML output.
41 Make YAZ checks Emacs friendly.
43 BITSTRING value shows value. Bug #2346.
45 ISO2709 decoding: skip control characters from indicator data.
47 Omit sort key by default in yaz-icu's output.
49 Allow combined single char options (again) for YAZ' options function.
51 Utility yaz-marcdump got option to display YAZ version (-V).
53 Allow YAZ to use ICU 3.4.
55 Added new ICU test case which illustrates removal of diacritics.
59 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
63 For configure, using option --without-xml2 also disables Libxslt/Libexslt
66 Fixed bug #2352: yaz-marcdump crashes for certain record.
68 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
70 Added support for Danmarc2 to UTF-8 conversion.
72 Added support for ISO5426 to UTF-8 conversion.
74 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
75 implementation version.
77 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
81 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
82 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
84 ZOOM C now interprets databaseName option for ZOOM connection as path
87 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
89 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
91 Dummy Libxml2 types no longer defined in headers of YAZ'.
93 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
98 Various ODR chapter fixes.
100 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
102 Added missing source for Windows compilation, mutex.c.
104 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
106 For SRU connections in ZOOM all records up to "count" are now fetched.
108 Fixed crash in generic frontend server (and yaz-ztest) which occurred
109 in Windows due to bad error handling for Libxml2.
111 Added facility for sending arbitrary records (ASN.1 any) using
112 ZOOM C's Extended service update. Patch by Sam Reynolds.
114 New options for ZOOM C's connection, logapdu which makes ZOOM log
117 --- 3.0.34 2008/06/18
119 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
121 --- 3.0.32 2008/06/12
123 Fixed memory violation that could occur when decoding UTF-8. This bug
124 was only present in 3.0.30 of YAZ.
126 --- 3.0.30 2008/06/06
128 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
129 GNU TLS is used by default (if found).
131 yaz-ztest returns OPAC records if a client asks for OPAC.
133 Improved speed of MARC-8 encoding.
135 Added support for lossy and loss-less MARC-8 encoding.
137 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
139 Added new Windows Service wrapper (sc).
141 yaz-client's itemorder command may now send a file.
143 Fixed yaz-marcdump to allow the use of NS prefix for record element.
145 Added new function yaz_log_xml_errors.
147 Allow (but warn) unknown XML attributes in MARCXML parsing.
149 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
151 The UTF-8 to MARC-8 conversion now uses a different set of characters
152 for Greek symbols. Bug #2120.
154 --- 3.0.26 2008/02/21
156 Added yaz_daemon (daemon.h).
158 Fixed bug #2068: pkg-config trouble
160 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
162 --- 3.0.24 2008/01/28
164 Document --with-xml2 option.
166 Added OPAC XML XSD (etc/opacxml.xsd).
168 Allow glob mask for name attribute in retrieval element for the
169 generic frontend server's retrieval facility.
171 Changed yaz_poll_poll to return yaz_poll_except for all returned events
172 except POLLIN/POLLOUT.
174 Fixed error handling in cs_listen. Bug #2037.
176 --- 3.0.22 2008/01/20
178 Fixed version in yaz/yaz-version.h.
180 Fixed bug #2027: Crash when closing connection.
182 Changed configure so that ICU support is only enabled if only ICU
183 and Libxml2 is available (because the ICU chain is XML based).
185 --- 3.0.20 2008/01/15
187 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
188 is built. Only this DLL depends on the ICU runtime.
190 yaz-ziffy is no longer part of YAZ. It is distributed separately by
191 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
193 Changed license of CCL module to 'Revised BSD'. After consultation with
194 remaining members of the original EUROPAGATE consortium, we are re-issuing
195 the CCL module without a separate license. The software was developed by
196 Index Data as part of a research project. The special license was included
197 to help feed usage information back to the project consortium to support
198 project evaluation. At this time, the project consortium has long-since
199 disbanded, and the majority of the original principals have retired. At the
200 same time, we have significantly modified the software during the following
201 years, to the point where very practically no original code remains. To
202 simplify re-use of the software, we have contacted those members of the
203 consortium who could be reached, and agreed to re-issue the module as a
204 proper part of the YAZ package.
206 Tcl scripts uses /usr/bin/tclsh as preferred shell.
208 CQL closer to being version 1.2 compliant. CQL also allows free-form
209 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
212 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
213 bug could make Extended services handling crash in the ZOOM layer. This
214 bug was only present in YAZ 3.0.18.
216 --- 3.0.18 2007/12/19
218 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
221 yaz-marcdump reads and writes collection wrapped records.
223 Handle OPAC for record conversion module.
225 Fixes for ICU wrapper.
227 Allow ICU libs to be controlled with --with-icu .
229 --- 3.0.16 2007/11/12
231 Added yaz_poll which is a wrapper for select/poll. When poll is available
232 and non-buggy, it is used, by yaz_poll . This allows more than 1024
233 sockets to be in use.
235 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
236 functionality through an XML based configuration (ICU chain). This system
237 is useful for search facilities such as Pazpar2 and Zebra that needs to
238 perform tokenization of indexed material. The ICU code in a separate
239 library libyaz3_icu.a.
241 Added HTTP tunnel facility for COMSTACK, bug #1752.
242 This is a facility that allows a Web proxy, such as squid, to tunnel
243 Z39.50 traffic. This facility is "transparent" to must applications
244 using YAZ. It's enabled by using pseudo transport connect: followed by
245 the proxy address, followed by command, then follwed by he regular
246 "virtual" addresss. For example,
247 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
249 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
251 --- 3.0.14 2007/09/21
253 Fixed bad memory reference in ZOOM_record - cuased by member not being
254 initialized. This was a problem only in YAZ 3.0.12.
256 Fixed bug in conversion from MARC to XML: Non-XML characters in control
257 fields were not removed.
259 Changed the way C code is generated from codetables.xml. Made a MARC-8
260 conversion trie for each characterSet section rather than codeTable.
261 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
262 of codetables.xml from Larry Dixson, LOC. Bug #1464.
264 --- 3.0.12 2007/09/12
266 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
267 from ZOOM_record_error).
269 ZOOM C function ZOOM_record_get returns record schema for type="schema".
271 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
273 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
275 Better SRW-to-Bib-1 diagnostic mapping.
277 ZOOM C and yaz-client announces SRU version 1.2 by default.
279 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
282 Fixed in yaz_sru_decode to allow other version than 1.1.
284 --- 3.0.10 2007/08/22
286 Added support for SRU scan for ZOOM.
288 Added support for the use of the older versions or Extended Service
289 Update in ZOOM. To faciliate this, an option "updateVersion" may be
290 set to the version , 1=first, 2=second, 3=third. The third version is
291 what ZOOM C has used so far. And that, obviously, is the default.
293 Added support for CCL queries in Z39.50 queries sent to the GFS (and
294 therefore in Zebra and in SimpleServer-based applications). The new
295 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
296 qualifier file used to transform incoming CCL queries into Type-1 RPN,
297 which is passed into the back-end search callback function.
299 Added support for HTTP Basic authentication in clients: the SRU/W
300 codec encodes the username/password elements of the PDU structure
301 appropriately, and these may be set using the "user" and "password"
302 options in ZOOM-C applications (the same options that are used for
303 Z39.50 authentication).
307 Fixed bug #1208: SSL appears to be broken in ZOOM.
309 Fixed bug #1206: Libxml2 include path weirdness.
311 Added oid_name_to_dotstring.
313 Allow elementSetName to be specified for ZOOM C record update.
315 Allow waitAction to be specified for ZOOM C based for Extended Services.
317 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
318 syntax OID. Bug introduced in YAZ 3 series.
320 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
324 Fixed bug #1157: yaz-client does not read .yazclientrc from current
325 directory. yaz-client now reads commands from file given by option -f
326 if specified; then tries to read .yazclientrc in current directory.
327 Failing that, it reads .yazclientrc from user's home directory.
329 Added support for correlationInfo Note and ID for Record Update via
332 Added yaz-client command querycharset which specifies character set for
333 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
334 (termListAndStartPoint).
336 Charset ISO5428:1984 is an alias for ISO5428-1984.
338 Implemented a way to perform scan in a result set using Z39.50. This
339 is achieved by attaching the result set name in the characterInfo
340 (type InternationalString) of OtherInformation in the Scan Request PDU.
341 The result set is identified in the otherinformation by the new OID:
342 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
343 This allows for scan in result set and faceted search . Zebra did some
344 of this in the APT term using attribute type 8 and value being result
345 set. Using the OtherInformation approach for this is cleaner and easier
346 to work with in proxies and the like. This facility can be used in
347 yaz-client using new command setscan which takes a result set as first
348 argument, start position (APT) as second.
350 Changed decoding of SRU XML packed records to deal with servers that
351 have recordData with XML data with multiple root nodes. Also make
352 comparison for recordPacking case insensitive. Again, one server
353 returns "XML" where others return "xml".
355 For SRU responses allow Content-Type application/xml as well as text/xml.
359 Fixed bug in character set conversion of BER strings. Bug introduced
364 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
366 For OID class, use oid_class consistently.
368 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
371 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
372 character set for bibliographic information interchange". By Giannis Kosmas.
374 Added documentation on new OID API.
378 Changes to generic frontend server interface: added new member
379 'query_charset' for bend_initrequest structure. A backend init handler
380 should set this member to its native character set for query terms.
381 When defined, the frontend server logic will announce this character set
382 to a client if the negotiationModel bit is set by the client. All server
383 implementors are encouraged to specify this. If a backend server does not
384 specify this a warning is issued using yaz_log(YLOG_WARN,..).
386 Added CCL utility to remove terms (stop words) from resulting RPN
387 tree. This is handled by functions with prefix ccl_stop_words_ .
389 New ZOOM C option, "rpnCharset", which allows client-side conversion of
390 terms in RPN queries.
392 Clean-up the CCL API. Moved some internal structures from ccl.h to
393 private header cclp.h. Changed ccl_parser_create so that a Bibset must
394 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
395 This is replaced by ccl_parser_find_str which takes a string instead.
397 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
398 libyaz.la is the core of YAZ except the generic frontend server and
399 does not depend on POSIX threads anymore. libyaz_server.la is the
400 generic frontend server facilities and uses POSIX thread functionality
401 if available. The libyaz.la no longer depends on POSIX threads because
402 the number of global structures is limited. NMEM no longer re-uses blocks
403 between threads ; it simply free's memory immediately but allocates in
404 "large" chunks as usual. We don't expect any performance penalties
405 because of this. The yaz_log system is still using a global log_level so
406 caution must be taken when modifying it with yaz_log_init_.. +
407 yaz_log_mask_str. This, however, should not cause any trouble because
408 these functions are called during initialization of application code
409 anyway. `yaz-config --libs server` returns libs for server applications;
410 `yaz-config --libs` returns libs for non-server applications.
412 New OID database - with public definitions in oid_db.h. Removed old OID
413 database including the head oid.h and definitions such as enum oid_value
414 and struct oident. The new OID database uses the same string names as
415 before but the 'protocol' is gone. There are now only two representations
416 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
417 converts from string to OID; functions with prefix yaz_oid_to_string
418 converts the other way.
420 Change to emit_term() in CQL-to-PQF query translation: when a term has
421 the /regexp relation modifier, do not process it for leading and
422 trailing "^" and "*", which have quite different meanings in regular
425 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
426 write handlers no longer carries a 'last' parameter. This will make
427 yaz_iconv flush "less" characters. A flush is performed by call to
428 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
430 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
431 removed, because function yaz_query_to_wrbuf does the same.
433 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
434 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
436 Deprecated MARC utility functions removed.
438 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
441 Branch split: YAZ_2_1_55_branch
443 --- 2.1.54 2007/03/16
445 Fix to ZOOM-C so that transparent reconnection is properly handled on
446 connections that are in asynchronous mode.
448 Fixed compilation on OpenBSD 4.0.
450 Large strings in GRS-1 records are now properly displayed in yaz-client.
452 Added character conversion support for "advancegreek"; based on patch from
455 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
456 sequence is met. Before the error was not set so it would be unknown.
458 Adjust yaz-marcdump MARC reader so that it skips until record separator
461 --- 2.1.52 2007/03/07
463 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
464 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
465 fd_set structure used as a bitmask for the FDs to be selected on.
467 Using ACX_PTHREAD macro to check for POSIX threads.
469 Fixed have-vsnprintf check.
471 --- 2.1.50 2007/02/23
473 Fixes for configure on BSD. Bug #900.
475 Added snprintf/vsnprintf wrappers for systems that don't have
476 limits (heavens forbid).
478 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
479 created before all previous tasks were completed and removed from the
480 task queue, the new task could be removed by a mistake.
482 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
484 Implemented pass-through CQL-to-PQF conversions. Bug #861.
486 Fixed bug #832: Problem with MARC/charset in yaz-client.
488 Fixed bug #668: save command line history for yaz-client.
490 Fixed bug #830: pkg-config support.
492 --- 2.1.48 2007/01/23
494 Extended ZOOM result set options with two options that may be read by
495 a client: resultSetStatus and presentStatus with values as specified for
497 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
499 Fixed bug #827: Using SSL fails on Debian etch.
501 Fixed bug #826: Weird looking chars for set of MARC records.
503 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
504 that is treated as an ItemOrder with itemRequest being an XML document
505 external. The value of "doc" is the content.
507 Extended the GFS search facility. New member of bend_search_rr
508 'estimated_hit_count' signals that hits is known to be an estmate
509 (higher or lower than real hit count). New member 'partial_resultset'
510 signals that the search was partial (hit count is lower or equal than
511 real hit count). For Z39.50, the information is stored in resultSetStatus
512 member of SearchResponse APDU. For SRU, the information is signalled
513 via SRU diagnostic 59: "Result set created with valid partial results
516 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
518 --- 2.1.46 2007/01/13
520 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
522 Added ZOOM_connection_peek_event.
524 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
525 the following new functions:
526 ZOOM_event_nonblock, ZOOM_connection_process,
527 ZOOM_connection_get_{socket,mask,timeout},
528 ZOOM_connection_fire_event_{timeout,socket}.
529 The existing blocking event handler, ZOOM_event, is a wrapper for the
530 + blocking ZOOM_event_sys_{poll,select}.
532 Implemented function ccl_xml_config which parses XML version of CCL
533 configuration (bug #798).
535 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
537 Added timings utility (yaz/timing.h)
539 --- 2.1.44 2007/01/03
541 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
544 Fixed bug #779: Rotation of apdu.log fails.
546 Fixed for character set conversions:
547 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
548 Honor G1 set in MARC-8 decoding.
550 --- 2.1.42 2006/12/17
552 Fixed bug #775: char conversion does not handle Alternative UTF-8
555 Implemented function yaz_marc_read_line which parses MARC line format
556 records. There is a wealth of formats out there. So far, this function
557 reads line records produced by yaz_marc_write_line.
559 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
560 more generic and easier to remember(!) options: -i format and -o format
561 which specifies input format and output format respectively - where
562 format is one of "marc", "marcxml", "line", "marcxchange".
564 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
565 does not print anything except warnings for records.
567 For yaz-marcdump, added support for MARC split into files (-s) with a given
570 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
571 spec, at http://www.loc.gov/standards/sru/record-update/
572 This has changed the binary layout of the following structs:
573 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
574 bend_update_rr . Patch by Ko van der Sloot.
576 Added GFS utility function bend_assoc_is_alive which returns 1 if
577 association is still alive (client is connected); 0 otherwise (client
578 closed connection). This allows busy servers to stop working for
581 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
582 been a separate piece of software. This version of ziffy has been modified
583 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
585 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
587 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
588 Client code may now interrogate options such as "init_opt_sort" to
589 find out whether the server claims to support various options.
591 --- 2.1.40 2006/11/27
593 Added utilities yaz_{set,get}_esn to set/get element set name from
596 Removed the build of libyazthread.la. The libyaz.so is the threaded version
597 of YAZ and has been so since YAZ 2.1.10.
599 Implemented ZOOM_record_error which returns error information for
600 record (surrogate diagnostic).
602 --- 2.1.38 2006/10/31
604 Updates for SRU Update by Ko van der Sloot:
605 1. Changed name from "operation" to "action"
606 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
607 versions in the code, marked as 'backward compatible'.
608 3. Added diagnostics for SRU Update.
610 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
612 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
614 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
616 For GFS, fixed problem with SRU diagnostic 'First record position out of
617 range' being issued for 0 hits.
619 zoomtst10 part of Windows Build.
621 --- 2.1.36 2006/10/13
623 Implemented yaz_filepath_comp which splits a path into file path
624 components (required by Zebra 2.0.3+).
626 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
627 BSD inspired license until now so this should not have any real impact on
628 anybody. See http://www.opensource.org/licenses/bsd-license.php
630 Fixed bug #687: Missing log lines.
632 Fixed bug #678: CQL to PQF translation does not preserve double-quote
635 Fixed bug #689: SRU diagnostics to be added.
637 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
638 whether a connection is idle (no more work do do).
640 --- 2.1.34 2006/10/04
642 Change type of optval from long to int for invocation of setsockopt with
643 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
645 Added support for specifying the max log file size for the Generic
646 Frontend Server. The size is given with option -r.
648 --- 2.1.32 2006/09/21
650 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
652 --- 2.1.30 2006/09/17
654 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
657 Fixed bug in Generic Frontend Server that could cause a server to stop
658 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
660 For the generic frontend server, the maximum record size is used as maximum
661 size of incoming packages (SRU + Z39.50). The value until was previously
662 only used in Z39.50 Init negotiation and, later, in a session controlled
663 sizes of records returned. This is controlled using -k option. It can be
664 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
666 --- 2.1.28 2006/09/04
668 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
671 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
673 New option for yaz-marcdump -lpos=value which allows setting a portion
674 of MARC header to a certain value.
676 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
678 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
679 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
681 --- 2.1.26 2006/08/15
683 Fixed problem with SRU mode type (soap, get, post) for yaz-client
686 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
688 --- 2.1.24 2006/08/08
690 Fixed MARC ISO2709 encoding routines to deal with character set
693 Minor changes to GFS logging. Database included in search request log
696 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
697 cached/multiple records.
699 Shared libraries are built by default on Unix+configure.
701 Changed cql2pqf transformation to use a different evaluation order. The
702 new order is: always, relation, structure, position, truncation, index
703 and relationModifier. Old order was: always, relation, relationModifier,
704 structure, index, position, truncation. Note that the the latter ones
705 override former ones for identical attributes.. The new scheme means that
706 it is possible to override any existing attribute with a relationModifier.
707 And also that it is possible to override everything for the index rule
708 (except the ones listed in relationModifier). No order is perfect but this
709 one, we believe, covers more real cases.. The "always" should have been
710 called "default", since the attributes there can be overridden with all
713 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
714 compilation phase, but also for yaz-config --cflags output. This allows
715 us to have public headers with Libxml2 stuff in them . It should also,
716 eventually, make Libxml2 checks redundant in packages using YAZ, such
719 --- 2.1.22 2006/06/15
721 Changed SRU update structure bend_update_rr so that SRU diagnostics are
722 stored in uri, message and details.. Previously diagnostics were stored
723 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
724 compatibility.. but he's probably the only one affected, so.
726 Added support for CCL, compiled on the client side, in ZOOM-C. This
727 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
728 input; the resulting query objects can be used for for searching with
729 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
731 YAZ' configure searches for OpenSSL by default.
733 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
734 SL_CTX_use_certificate_file. See
735 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
736 for more info. Thanks to Ko van der Sloot.
738 --- 2.1.20 2006/06/02
740 Bug #600: SRU GET, POST support for yaz-client. Introduced
741 command 'sru' which selects method SOAP/GET/POST.
743 Allow missingValueAction to be specified for the sortspec string -
744 function yaz_sort_spec. By default, the missing value action is null.
745 Use ! to specify "abort". Use = followed by stringvalue to specify default
748 Ensured that Present-handler (if defined) is called in GFS before any call to
749 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
750 searchRetrieve requests.
752 Documentation for YAZ is now based on the Docbook XML/XSLT using
753 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
754 is no longer depending on jade/openjade or docbook-to-man scripts.
755 PDF is no longer part of the distribution - but can optionally be
756 made using DSSSL/jadetex or FOP.
758 Added retrieval handling support in Generic Frontend Server to support
759 conversion between MARC/XML as well as XSLTtransforms. See
760 etc/yazgfs.xml for an example.
762 Added Authentication support to Generic Frontend Server in SRU
763 mode. Authentication using HTTP Basic is supported, as is the use
764 of 'x-username' and 'x-password' parameters in the request itself.
766 Added support for a new character set MARC8s identical to MARC8 except
767 that it converts combined characters to single Unicode characters in the
768 Latin-1 range (when possible).
770 --- 2.1.18 2006/04/24
772 ASN.1 compiler 0.4: generates brief Doxygen file header for
773 generated .h/.c files.
775 Utility yaz_iconv now supports conversion to MARC-8.
777 New facilities for the MARC module. The reading - and writing of
778 content are separate methods for the yaz_marc_t handle. The following
779 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
780 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
781 format). Write functions have prefix yaz_marc_write_.. The existing
782 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
783 available. Removed support for OAI-MARC and simplexml (not the
784 simplexml from PHP5).
786 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
787 to be returned for this connection.
789 --- 2.1.16 2006/03/31
791 Allow multiple languages and charsets to be specified with
792 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
793 negcharset iso-8859-1,utf-8
795 Translation of proximity nodes from CQL into PQF now works.
797 Moved to automake 1.8, 1.9.
799 Added function yaz_log_set_handler which allows a log handler to be
800 installed. This handler will be called for all log messages. Output
801 to file is also produced; but that can be disabled by passing NULL
802 fname to yaz_log_init_file.
804 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
806 For SRW (including GFS), accept application/soap+xml as content-type
809 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
810 produces NO stylesheet reference even if a default stylesheet is specified
813 --- 2.1.14 2006/03/14
815 Updated Windows package to include yazd.dll + yazd.lib for the
816 Development component.
818 If the environment variable YAZ_LOG is set, then it is used as a
819 string indicating the default level of logging to use if not
820 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
821 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
822 used as before. So, for example, to omit warnings from YAZ logging,
825 cql_transform() now map structure and other attributes before indexes,
826 so that index-specific structures and other attributes can override
827 defaults. So now a combination of mapping specifications such as:
829 index.dc.date = 1=date-modified 4=5
830 does the right thing.
832 cql_transform() now also respects the "always" mapping specification,
833 which establishes an initial set of attributes to be used for all
834 terms except where overridden by more specific attributes associated
835 with the index, relation or modifier.
837 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
838 which mode to use; one of "post", "get" or "soap" (SRW, default).
840 Fixes for yaz_iconv routines: changed trie-based character set conversions
841 to use only non-negative values for bit fields due to Sun's C compiler not
842 supporting negative values.
844 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
845 sequences where not read correctly. Fix by Rustam Usmanov.
847 Updated win/makefile to use options, settings which makes things
848 compile with VS C 2005.
850 --- 2.1.12 2006/02/01
852 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
854 In ZOOM socket code, use select instead of poll on MacOSX.
856 ZOOM-C now support client-side compilation of CQL into RPN that is
857 sent to the server, enabling CQL to be used against all Z39.50
858 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
859 ZOOM_query object, and submit it using ZOOM_connection_search().
860 The CQL-to-RPN translation uses a configuration file, the name of
861 which must be specified in the Connection's "cqlfile" option.
863 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
864 function, which takes as its start-term parameter a ZOOM_query object
865 (which may have had either CQL or RPN set into it).
868 --- 2.1.10 2005/11/29
870 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
871 GFS to support this as well. Backend handler, bend_srw_update, does the
872 update work. Code contributed by Ko van der Sloot.
874 Allow retrieval of Search Result-1 information in ZOOM by the use of
875 options that are attached to a result set. ZOOM documentation updated
878 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
879 UTF-8 conversion. Patch by Raj Patel.
881 Added option -m to GFS to control formatting of timestamps in log file.
883 Added 'exit' as synonym for 'quit' in yaz-client
885 Added support for specifying SRW resultSetId + resultSetIdleTime in a
886 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
887 for the new members. Patch by Ko van der Sloot.
889 Added support for SRU POST. It is supported for content-type
890 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
892 Do not build the separate Multi-threaded (MT) library libyazthread.la.
893 Instead make the library libyaz.la multi-threaded. Threading as a whole
894 can still be disabled by configure option --disable-threads. Previosly,
895 with older GLIBCs there were problems with MT libs under Apache. This
896 has now been fixed a long time ago.
898 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
901 CQL module modified to be case insensitive for relations/indexes/operations.
903 Fixed bug in CQL transform code: incorrect value relationModifieder
906 Added 'show all' command for yaz-client which retrieves all results
909 Added new yaz-client, xmles, which takes a (private) OID and
910 a document to be sent as an extended service request.
912 Describe new yaz-client commands wait_response and set_auto_wait.
914 Increase TCP/IP listener backlog from 3 (which I am guessing was
915 copied from the SunOS manual entry way back when) so SOMAXCONN, so
916 that the socket will queue as many incoming connections as it's able
917 to handle ongoing connections. In other words, it will never now
918 refuse a connection that it would be able to handle merely because
919 it's not got around to accepting() enough of the pending connections
920 yet. This is the behaviour anyway under Linux, where the listen()
921 argument is ignored; but not under BSD and on systems such as
922 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
923 YAZ-based servers should now be uniform across operating systems in
926 yaz-marcdump uses 64-bit file access on some systems. This is enabled
927 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
928 This allows yaz-marcdump to read large MARC batches (>2 GB).
930 Modified all YAZ source files - except the source which is auto-generated
931 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
934 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
935 corresponding to the existing *_setl() function. These allow option
936 values containing arbitrary valuues.
938 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
939 ZOOM_resultset_sort() in new applications. Its behaviour is identical
940 except that it returns an indicator of whether or not the sort
941 criterion was accepted (0 for OK, -1 for invalid).
945 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
946 MARC output rather than returning "new" buffer.
948 yaz-client warns about unknown init options.
950 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
954 Added support for SRW sort in Generic Frontend Server. Patch
955 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
956 sortKeys - or NULL if none is provided.
958 Fixed bug #307: It was impossible to specify indefinite/no timeout
959 for ZOOM_event. Special timeout value -1 now means indefinite timeout
962 Added support for multiple languages and charsets to be specified in
963 ZOOM. Each charset/language is separated by a blank. If negotiation is
964 in effect in init-response, Option
965 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
966 Code based on patch by Vasiliy Osadchuk.
968 Fixed bug #306: infinite recursion that occurred when calling
969 yaz_log_level_init as the first call (before other log level or
972 Fixed bug in scan handling in front end server: if preferred-Position-In-
973 Response was non-present, a NULL pointer referece was performed.
977 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
978 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
979 now defined for all those error codes. So instead of putting 109 in
980 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
981 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
983 Modified the yaz-marcdump utility to skip garbage bytes between MARC
986 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
988 Program yaz-client now exits and produces an error message if multiple
989 Z39.50 servers are specified on the command line (none or one allowed
992 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
997 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
999 Fixed bug #272: Preserve spacing for CCL terms.
1001 --- 2.1.0 2005/03/14
1003 Added support for virtual hosts and multiple backend servers for
1004 the YAZ frontend server. The configution is XML based and
1005 support specificition of CQL to RPN mappings and explain information.
1006 See section "Virtual Hosts" in the YAZ manual.
1008 Extended OPAC display utility. OPAC display utility renders
1009 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1010 to supplement yaz_marc_decode_wrbuf.
1012 Fixed a bug in MARC decoder that could caused it to crash for some
1013 invalid MARC records. More diagnostics and warnings where added in
1014 XML output (warnings, etc are stored in comments).
1016 --- 2.0.34 2005/02/08
1018 Fixes for UNIX domain sockets. Bug #261.
1020 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1022 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1023 Added yaz_marc_subfield_str which defines subfield lead string which is
1024 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1025 yaz_marc_endline_str which defines end of fields string used in
1026 YAZ_MARC_LINE format. Default string is newline.
1028 Experimental support for MarcXChange. This format can be produced
1029 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1030 http://www.bs.dk/standards/MarcXchange.xsd
1032 Added yaz-client commands scansize that sets maximum number of
1033 entries to be returned by scan.
1035 --- 2.0.32 2005/01/11
1037 Added support for SRW scan in yaz-client and Generic Frontend Server.
1039 * Added whereInList member to SRW Scan Term.
1041 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1043 Fixed NMEM system to return aligned blocks on the smallest boundaries
1044 that are suitably aligned for all possible types on the particular
1045 architecture YAZ is being built for.
1047 --- 2.0.30 2005/01/04
1049 Fixed numerious warnings that was issued with newer versions of GCC.
1051 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1052 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1055 Make YAZ Generic Frontend Server slightly faster.
1057 Enhance (and reduce) logging for Generic Frontend Server.
1059 Revert YAZ log system so that it flushes every write operation
1060 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1062 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1063 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1064 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1065 will effectively disable old definitions.
1067 --- 2.0.28 2004/11/09
1069 Added yaz_log_time_format which specifies log format using
1072 Added yaz_log_module_level which returns mask for a module. Value
1073 is non-zero mask a if module is enabled; zero if disabled.
1075 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1076 in include/yaz/cql.h.
1078 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1080 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1082 Fixed bug #172: RPM builds does not enable SSL.
1084 Doxyfile.in part of dist. Doxyfile generated by configure.
1086 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1087 are given and the corresponding component does not exist.
1089 Extend CCL documentation in YAZ reference. Describe r=r.
1091 --- 2.0.26 2004/10/01
1093 Fixed MARC->MARCXML conversion to properly deal with
1094 fields, subfields, indicators having non-ASCII characters.
1096 Fixed MARC->MARCXML conversion so that ASCII control characters
1097 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1100 Added YAZ GFS support for conversion from Z39.50 surrogate
1101 diagnostics to SRW surrogate diagnostics.
1103 Bug fix: YAZ GFS did not return schema in explainResponse.
1105 --- 2.0.25 2004/09/30
1107 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1108 now converts recordSchema to elementSetName as well as schema URI.
1110 Fixed bug in COMSTACK that prevented HTTP request packages from being
1113 --- 2.0.24 2004/09/29
1115 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1116 does not require white-space before and after the dash in a range, e.g.
1117 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1120 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1121 due to new GCC removing "redundant" code.
1123 Added yaz-client commands scanpos and scanstep that sets preferred
1124 position and step-size for scan.
1126 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1128 Added CCL utility ccl_qual_buf which parses one or more CCL
1129 spec lines in a buffer.
1131 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1132 of name and value - ignoring empty lines and comments.
1134 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1136 Added odr_get_element_path which returns current element path for an
1137 ODR handle. This utility is useful in error handling or user-defined
1140 Added ODR_PRINT utility odr_set_stream which is is a more generic
1141 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1142 to a write function and pointer to close function. The close function - if
1143 non-NULL - will be called during odr_destroy.
1145 Fixed bug in CCL parser where truncation char was not removed from
1146 right side when truncation=both was in effect.
1148 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1151 --- 2.0.23 2004/08/11
1153 Fix buffer overrun in CQL parser when dealing with proximity (%).
1155 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1156 to UTF-8/UCS conversion is now only based on codetables.xml.
1158 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1160 --- 2.0.22 2004/08/06
1162 Add support for more "commit changes" in ZOOM (uses Extended Services).
1164 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1167 Yet another small fix for configure of SSL.
1169 --- 2.0.21 2004/05/14
1171 Fix SSL libs for configure when --with-openssl=DIR is given.
1173 --- 2.0.20 2004/05/10
1175 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1177 SSL comstack now uses yaz.pem certificate file on server side
1178 by default. Certificate filename can be configured by calling
1179 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1181 Fix bug regarding multiple calls to ZOOM_connection_connect.
1183 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1185 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1186 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1188 ZOOM now allows inspection of X509 peer certificate for verification.
1189 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1191 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1192 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1193 as "modular" but it simplifies things.
1195 Added cs_get_peer_certificate to that returns peer X509 PEM.
1197 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1198 NULL if SSL is unavailable.
1200 Documentation about MARC decoding tools.
1202 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1204 --- 2.0.19 2004/03/30
1206 Rename CHANGELOG to NEWS to follow GNU style packing.
1208 Fix bug with missing initialization of member in init_diagnostics.
1209 This bug affects threaded version of GFS server.
1211 --- 2.0.18 2004/03/20
1213 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1216 Ensure zlib.dll is packed with Windows install.
1218 --- 2.0.17 2004/03/17
1220 Fix encoding of xsd:string to use text instead of CDATA.
1222 Fix endless loop in CQL parser with unbalanced ".
1224 Use a more compact way to store MARC-8 conversion tables.
1226 --- 2.0.16 2004/03/16 Debian only
1228 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1231 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1236 --- 2.0.15 2004/03/01
1238 Another fix for decoding of XML packed records.
1240 --- 2.0.14 2004/02/25
1242 Fixes for Chunked encoding. White space not ignored after length spec.
1244 Update NS and use default NS for SRW diagnostic elements.
1246 --- 2.0.13 2004/02/23
1248 Implement ZOOM_resultset_cache_reset which resets record cache.
1250 Implement ZOOM_resultset_sort which sorts a result set.
1252 Implement chunked HTTP transfer.
1254 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1256 --- 2.0.12 2004/02/16
1258 Added member 'schema' to bend_explain_rr structure so that backend
1259 can specify explain record identifier. Defaults to Zeerex 2.0.
1261 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1263 --- 2.0.11 2004/02/16
1265 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1268 Added init command for yaz-client which sends "extra" init request.
1270 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1271 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1273 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1275 Make ZOOM error code for "invalid query".
1277 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1279 --- 2.0.10 2004/02/05
1281 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1284 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1286 Added option -p <file> to make Generic Frontend Server to write PID file.
1288 Added option -D to put Generic Frontend Server in background on its own.
1290 Make ZOOM C recognize option "password". If unset, "pass" is used
1291 (for backwards compatibility).
1293 Fixed a bug in Generic Frontend Server that could make it crash if a
1294 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1297 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1298 Must be issued before open, in order to be in effect.
1300 --- 2.0.9-6 2004/01/12 Debian/Windows
1302 Make the SRU server more picky WRT unknown params, etc.
1304 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1306 New YAZ client command, options, that sets Z39.50 options.
1308 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1309 options from a string of tokens (one token for each option bit).
1311 Update SRW diagnostic code messages.
1313 --- 2.0.9-5 2004/01/07 Debian/Windows
1315 Handle user defined stylesheet for SRW/SRU.
1317 --- 2.0.9-4 2004/01/06 Debian/Windows
1319 Fix bug in decoding of Content-Length.
1321 --- 2.0.9-3 2004/01/06 Debian/Windows
1323 Fix a bug with decoding of XML packed records.
1325 --- 2.0.9-2 2004/01/05 Debian only
1327 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1329 Fix bug in SRW/SRU diagnostics decoding.
1331 --- 2.0.9 2004/01/05
1333 Fixed bug in Generic Frontend Server which could drop records exceeding
1334 preferred message size. Reported and fixed by Irina Dijour.
1336 Fixed calculation of package size for structured records in Generic
1337 Frontend Server. Reported and fixed by Irina Dijour.
1339 Fixed namespace for SRW/SRU diagnostics.
1341 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1343 --- 2.0.8 2003/12/22
1345 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1346 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1349 CQL changes to reflect recent changes to the specification:
1350 * Documentation talks about context sets instead of index sets.
1351 * Documentation talks about indexes instead of qualifiers.
1352 * The CQL-to-PQF transformer's configuration file now uses
1353 "index.set.name = <attributes>" instead of the old form
1354 "qualifier.set.name = <attributes>". (Both forms are still
1355 understood but the latter is deprecated.)
1356 * CQL terms with no explicit index specified are now interpreted as
1357 cql.serverChoice instead of srw.serverChoice (which of course
1358 behaves exactly the same.)
1360 --- 2.0.7 2003/12/16
1362 MARC conversion can now generate ISO2709 output in another
1363 character set. yaz-marcdump uses this facility if you invoke it
1366 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1367 functions from there can be used from C++.
1369 --- 2.0.6 2003/12/04
1371 Frontend server now transfers memory from decoded packages to stream
1374 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1375 references to show up.
1377 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1378 the ZOOM Abstract API. The older names for the same options are still
1379 also supported for the benefit of old applications.
1381 ZOOM-C supports "implementationId" and "implementationVersion" options
1382 to go along with "implementationName". These allow the user code to
1383 specify identification strings to be sent to servers.
1384 Add OID for the new ExtLite attribute set.
1386 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1387 as requested/supplid by Ere Maijala <ere@atp.fi>
1389 For generic frontend server, reverse the order of
1390 "toolkit-supplied / application-supplied" strings sent as implementationId,
1391 Name and Version. Also, remove the spaces around the slash. This brings
1392 the GFS in line with the behaviour of ZOOM-C on the client side.
1394 Add function ZOOM_scanset_display_term.
1396 yaz-client shows scan displayTerm if present.
1398 Utility yaz-iconv is now installed by default along with the man page
1401 Extend configure check for OpenSSL to use pkg-config where available (such
1404 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1405 server to specify uid/gid/mask for socket using the format
1406 unix:[user=uid,][group=gid,][umask=mask,]file=path
1407 If file= is omitted the existing format is assumed, e.g.
1409 in which case the mask is 0666 (rw for everybody).
1411 Major restructure of YAZ source. All source in libyaz is in src directory.
1412 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1413 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1415 Added man page for utility yaz-marcdump (used to be called marcdump).
1416 yaz-marcdump is installed by 'make install'.
1418 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1419 of incoming package failed.
1421 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1423 Change prototype of odr_perror: add const to message string.
1425 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1427 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1428 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1429 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1430 DNS lookup. There should not be any compatibility problems with this
1431 assuming that blocking=1 or 0 is used.
1433 Fix bad reference in UNIX comstack in function cs_addrstr.
1435 Fix for compilation on AIX.
1437 The generic front-end server (server/seshigh.c) now supports returning
1438 Init diagnostics to the client in User-information-field, in
1439 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1442 --- 2.0.4 2003/09/04
1444 Allow any CQL relation (not just all,any,exact,scr).
1446 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1447 that features the same UI.
1449 Implemented command update0 in YAZ client which is equivalent to
1450 update but uses old of Ext Update ASN.1.
1452 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1453 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1454 Previously no OID was used for this info.
1456 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1457 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1458 returns 'malformed search term' otherwise.
1460 SortResponse member resultCount now set to NULL in sort handler of
1463 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1466 Add three new utility functions for translating OIDs between various
1467 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1468 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1469 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1470 char *oid_to_dotstring(const int *oid, char *oidbuf);
1471 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1473 Reverted modifications for ES Update definition for z_IU0Update
1474 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1475 is back to YAZ 2.0.2.
1477 String value attributes for CCL parser.
1479 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1480 which their FirstSearch server returns in Init responses, sometimes
1481 carrying useful diagnostic information when Init fails. This has the
1482 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1483 "z39.50/oclcui.asn", where its definition is somewhat different from
1484 what OCLC document on their web-site, as required to interoperate with
1487 Support for anonymous authentication in yaz-client. Use the command
1490 * Fix the OID of the Index Data-local "admin" Extended Service from
1491 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1492 the 1000, which indicates a locally-defined OID, was a mistake.
1494 --- 2.0.3 2003/06/20
1496 Fix CCL directive @case handling so that it affects string match for
1497 both CCL keywords and qualifiers.
1499 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1500 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1501 Decoder has been updated with ASN.1 changes as listed in
1502 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1503 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1504 z_IUUpdate, remains unchanged.
1506 ZOOM_record_get may now return a record in a specific character set.
1507 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1508 "from" is the character set of record as returned by target. "to" is
1509 the character set to be returned. If omitted, "to" is UTF-8.
1511 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1513 New ODR utility, odr_getelement, which returns name of element for
1514 which encoding/decoding failed.
1516 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1517 in cases where a required element was omitted.
1519 Bug fix: some MARC8 sequences were not converted.
1521 New ZOOM option "step" which specifies number of records to be
1522 retrieved in one chunk. Used in conjunction with "start" and "count".
1524 SRW support for yaz-client. Use scheme http: to use it, e.g.
1527 yaz-client no longer does (un)intelligent character set conversions
1528 by default. Can be enabled with charset and marc_charset commands.
1530 xmalloc trace fix for 64-bit systems such as DEC alpha.
1532 Solaris 2.6 compile fix.
1534 New function, cql_strerror() translates SRW error codes, as returned
1535 by cql_transform_error(), into human-readable English strings. Used
1536 in yaz-client diagnostics when appropriate.
1538 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1539 converts it into a type-1 query which is sent to the server. This
1540 makes CQL available for use with all Z-servers, as opposed to the tiny
1541 minority that can handle CQL queries themselves.
1543 --- 2.0.2 2003/04/28
1545 New Debian package layout similar to the Redhat Package layout.
1547 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1548 and search result respectively.
1550 --- 2.0.1 2003/04/25
1552 Redhat package is now several packages: libyaz (runtime libraries),
1553 libyaz-devel (development and documentation, and yaz (utility programs).
1554 Package spec file by Morten Bogeskov.
1556 New member 'schema' in struct bend_fetch_rr which the name of requested
1557 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1558 handler MAY set this to reflect the schema of the returned record.
1560 New member 'display_term' in struct scan_entry. GFS now sets member entries
1561 and allocates scan entries to be filled by user scan handler. In previous
1562 version, entries member was allocated by the scan handler. That still works,
1563 but the GFS will ignore member display_term - assuming it was NOT set by
1564 the handler. The fact that the GFS now allocates the entries both allows
1565 for new members and makes a scan handler easier to write.
1567 Fix CQL lex buffer overflow.
1569 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1570 SRU default recordPacking is string.
1572 SRU protocol support for frontend server.
1574 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1576 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1578 Added scan for the ZOOM shell (zoomsh).
1582 * String Identifers for Schemas (Amendment 5).
1583 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1584 Old definition for schema
1585 Odr_oid *schema; /* OPT */
1590 Z_InternationalString *uri;
1591 #define Z_Schema_oid 1
1592 #define Z_Schema_uri 2
1595 * resultCount parameter to Sort Response (Amendment 1).
1596 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1598 Support for SRW 1.0 over HTTP. This is an optional feature and
1599 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1602 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1603 on the same port. SRW SearchRetrieveRequests are mapped
1604 to bend_init,bend_search,bend_fetch,bend_close.
1606 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1608 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1609 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1611 ZOOM connections are SRW based if schem http is used for hostname
1612 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1613 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1615 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1616 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1617 distance=n, order=true/false, relation=le, prox unit=word. If
1618 n is omitted, distance 1 is used.
1620 Fixed problem with C compiler include path in wrong order.
1622 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1623 on Solaris. Patch from Ko van der Sloot.
1625 New MARC decode API. All new functions operate on a yaz_marc_t
1626 handle. The most important new functions are: yaz_marc_create,
1627 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1628 decode and destroy respectively. Decoder can produce formats
1629 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1630 include/yaz/marcdisp.h.
1632 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1633 to UTF-8, UCS-32, wchar_t or Latin-1.
1635 * Prototypes for yaz_iconv_-functions moved to separate header
1636 include/yaz/yaz-iconv.h.
1638 Make a few private functions 'static' in unix.c. This prevents
1639 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1641 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1642 are set when Init Response is received.
1644 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1645 but returns diagnostic set as well.
1647 New function yaz_strerror which is a portable wrapper for
1648 strerror/strerror_r/GetLastMessage.
1650 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1651 is returned for MARC. If type is "oai", then OAI MARC is returned.
1653 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1656 --- 1.9.2 2002/11/26
1658 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1660 Fix bad race conditions on SIGTERM and terminate gracefully in
1663 Move retrieval (data1) module to Zebra since nobody seems to be
1666 Add GRS-1 render for ZOOM using same format as yaz-client.
1668 --- 1.9.1 2002/10/05
1670 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1672 Fix broken ESpec handling in data1 module.
1674 SGML reader parses comments and makes them part of the data1 tree.
1676 Added several type casts so that YAZ compiles as C++ code.
1678 ZOOM didn't handle PDU encoding failures properly.
1680 Added more Bib-1 diagnostics (approved extensions).
1682 GNU configure: better check for iconv.
1684 More portable use of accept, getpeername. Check for socklen_t. Use
1685 int/size_t if socklen_t is not defined.
1689 PQF parser rejects bad queries - including those with extra
1690 characters in them. PQF parser used to silently ignore that.
1691 Cleaner API for PQF added, which allows you to get detailed
1692 error information for bad queries (see yaz/pquery.h).
1694 Fixed bug in ZOOM_record_get for type "database".
1696 Implemented mini iconv library supporting conversions between
1697 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1699 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1701 --- 1.8.9 2002/08/20
1703 Fixed ZOOM C record cache so that preferredRecordSyntax and
1704 elementSetName is used to check for already fetched records.
1706 --- 1.8.8 2002/08/02
1708 Added three members in bend_initrequest structure to facilitate
1709 character set negotiation.
1711 Fixed a bug in frontend server that could cause indefinite
1712 loops under rare conditions.
1714 Revised character set utilities (charneg.h) so that encoding
1715 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1717 For PQF, directive @term <type> sets term type for Scan/Search.
1718 Here <type> is general, string, numeric, null. The term type
1719 is inherited - just like @attr.
1721 New call odr_set_charset that sets character set conversion for
1722 international-strings on a ODR stream. Prototype is:
1723 int odr_set_charset(ODR o, const char *to, const char *from);
1724 The InternationalString is still represented as C string in YAZ
1725 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1726 won't). On the protocol level, you can use any encoding.
1728 Support for UNIX sockets in ZOOM.
1730 Solaris recv sometimes returns errno == ENOENT. It is treated as
1731 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1733 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1734 both client and server. Code by Morten Bogeskov.
1736 --- 1.8.7 2002/05/22
1738 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1739 that they can be used directly from Visual Basic. You must recompile
1740 your windows APP if you're using ZOOM.
1742 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1743 Commands "lang" and "charset" sets language and character set respectively.
1744 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1745 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1747 Attributes from multiple CCL fields may be OR'ed rather than merged
1748 using directive "@field or". Fields are still merged by default -
1749 equivalent to "@field merge".
1751 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1754 Fixed bug in zget for parameter ExtendedServicesResponse.
1758 --- 1.8.6 2002/03/25
1760 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1762 Client displays USR.1:SearchResult-1 (hits per term).
1764 Additional Search Info for search in Generic Frontend Server.
1766 Fixed CCL parsing of "field=s".
1768 WIN32 installer - using the excellent NSIS software from nullsoft.
1770 Fixed CCL parsing of "field = - <number>".
1772 Added function yaz_marc_decode that decodes MARC for line mode
1773 display or XML (similar to that used by JZKit).
1775 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1776 Z39.50. But ISO/ILL was, however.
1778 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1779 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1781 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1782 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1784 --- 1.8.5 2002/02/03
1786 New YAZ client features: Command completion and new commands:
1787 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1788 Code provided by Jacob Poulsen.
1790 New call oid_trav, that visits all registered OIDs via callback.
1792 Function ZOOM_record_get now returns const char pointer rather than
1793 void pointer. It saves a lot of type casts.
1795 For YAZ client, command "auth" now allows you to set authentication
1796 in IdPass style. It is enabled when three tokens are given - order
1797 is user, group and password.
1799 Fix memory leaks in MARC record handling for ZOOM.
1801 New option for YAZ client, -k <kilobytes> that sets
1802 maximum record size. Similar to -k option for generic frontend
1803 server and yaz-ztest.
1805 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1807 Prefix query parser reports "fail" when bad attribute set is given.
1809 Fix in MARC decoder. Proximity logging. Fix for attribute set
1810 in scan handler for server. Patches by Shigeru Ishida.
1812 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1815 Configure option --with-openssl=<dir> now works when a directory is
1816 specified. Patch provided by Morten Bogeskov.
1818 New option for YAZ client, -u <auth>, that sets authentication.
1820 ZOOM fix: error information was sometimes "missing", since error
1821 was cleared/reset too when it shouldn't.
1823 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1825 --- 1.8.4 2002/01/04
1827 Scan for ZOOM API. New object ZOOM_scanset. New functions
1828 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1829 ZOOM_scanset_destroy.
1831 New ZOOM function, ZOOM_connection_last_event, that returns type
1832 of last event (such as "receive data", "send data", "apdu received",
1835 New ZOOM option, schema, that specifies schema for retrieval.
1837 New CCL feature. Qualifiers can be aliases for one or more
1838 other qualifiers (if more than one is given, OR is used).
1840 ZOOM uses named result sets if target supports it.
1842 Two new YAZ client commands: . (dot, which sources a script of YAZ
1843 client commands), and ! (to execute shell command.). Implemented
1846 Working on Debian packages.
1848 --- 1.8.3 2001/11/19
1850 YAZ client enables named result sets only if target supports it.
1852 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1854 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1855 with key="host" to get same result.
1857 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1858 Function Z3950_resultset_record(s) returns references to records
1859 "owned" by resultset. To become owner use Z3950_record_clone.
1861 Function z_ext_record handles Extended Services. Thanks to
1864 --- 1.8.2 2001/11/12
1866 CCL Parser fix: ignore token comma when dealing with and-lists.
1868 Documentation updates for COMSTACK.
1870 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1871 Changed prototype Z3950_records. For some functions, int parameters
1872 were changed to size_t.
1874 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1877 New MARC decode/display function, marc_display_exl, which properly rejects
1878 non-ISO2709 records. YAZ client uses it.
1880 --- 1.8.1 2001/10/29
1882 Fix bug: local attribute set wasn't set correctly in PQF strings.
1886 * Old Z39.50 codecs no longer supported.
1888 Added ZOOM C binding. See http://zoom.z3950.org/
1890 Renamed states for COMSTACKs to avoid confusion with events.
1892 Implemented cs_look and proper cs_rcvconnect.
1894 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1896 Configure detects POSIX threads on OpenBSD.
1898 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1899 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1901 When error is returned from present handler, non-surrogate diagnostic
1902 is returned in present response (and fetch handler is no longer called).
1904 * Minor adjustments to pquery parser (PQF). Token characters may be
1905 escaped by using backslash (C-style).
1907 PQF parser allows string attribute values to be specified. For @attr,
1908 non-numeric characters after the equal-sign are treated as strings
1909 (e.g. @attr 9=title).
1911 CCL trunction character may be defined (@truncation in file)
1913 * function zget_ExtendedServicesRequest sets waitAction to
1914 waitIfPossible (was wait).
1916 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1919 CCL operator names may be set in field definition files (CCL_bibset).
1920 See ccl/bib1 for an example.
1922 Fixes in ASN.1 compiler for C++ compatibility.
1924 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1925 and "op_or" to avoid conflict with C++.
1927 Fixed problem with GNU readline detection on Redhat 7.0.
1929 Added step-size for Scan backend handler.
1931 Fixed bug that made the frontend server crash when no attribute
1932 set was specified for scan.
1934 Front-end server automatically switches to original working directory
1935 when installed as an NT service. Previously -w had to be specified to
1938 Added extended attributes for retrieval module (data1), so that data1
1939 records carry d1_readXML/SGML attributes. d1_read also supports
1940 null-data rules ( <tag/>)
1942 On UNIX when POSIX threads are available, a separate library libyazthread
1943 is created. Programmers should link with that library and the yaz library
1944 when using threads. The reason for the split was that some applications
1945 on Linux, such as Apache, doesn't work well when using shared objects that
1948 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1949 (or any frontend server) in SSL mode by specifying ssl: followed by
1950 address. Only tested on UNIX.
1952 Added feature for CCL module. Virtual structure s=al or s=ol generates
1953 and-list and or-list respectively instead of phrase search.
1957 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1958 log_mask_str. This was done to avoid name conflicts with other libraries
1959 (such as other PHP extensions).
1961 Added raw OID member for preferred record syntax (request_format_raw)
1962 and returned record syntax (output_format_raw) for backend fetch method.
1964 Config file yaz-config now accepts options so that it returns specific
1965 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1967 Shared library support for UNIX using GNU libtool.
1969 * Modified backend interface. Request/Response struct's replaced by
1970 one read/write C struct. For example bend_fetchrequest and
1971 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1972 Every handler - even search has to be registered in bend_init
1973 handler. This means that the YAZ library no longer refers to
1974 external functions and it makes it possible to make the whole
1975 thing a single DLL/SO.
1977 Added Segment handler for backend server.
1979 Added Zmbol/Zebra administrative functions to YAZ client.
1981 Threaded frontend server on UNIX (when POSIX Threads are available).
1982 Starting the server with option -T enables multi-threading.
1986 Added configure option --enable-comp/disable-comp to control use
1987 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1988 located in sub directory asn.
1990 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1991 in ${exec_prefix}/bin along with the other programs yaz-client and
1994 GNU automake used to maintain makefiles.
1996 Added several OID's.
1998 Changed retrieval module so that we can load records with no abstract
1999 syntax defined. Tagpaths in these records are fully composed of string
2002 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2006 On UNIX, the generated makefile now supports a proper 'make install'.
2007 The prefix can be set via GNU configure to set the install location
2008 (default is /usr/local).
2010 * YAZ programs client and ztest were renamed to yaz-client and
2011 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2012 locations, such as /usr/bin,/usr/local/bin,etc.
2014 * YAZ Header files were moved from include to include/yaz. YAZ Header
2015 files are referred to as include <yaz/log.h> rather than <log.h>.
2016 The YAZ include path (-I ..) is therefore the same as before. Programmers
2017 should update their #include statements or use -Ipath/include/yaz
2018 instead. The main motivation for doing this change is that YAZ header files
2019 can be installed in "standard" locations /usr/include,/usr/local/include
2020 without introducing conflicts, since ALL YAZ header files are stored
2021 in subdirectory yaz (under /usr/include for example).
2023 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2024 rather than project/workspace files. We switched because project files
2025 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2028 Changed name of logging function, logf, to yaz_log, to prevent name
2029 clash with some math-log functions. The YAZ header log.h defines logf
2030 to yaz_log (#define) so there should be no incompatibilities by this
2033 Added bend_start/bend_stop handlers for server. These handler are
2034 called on start/stop of server. For windows they are called whenever
2035 a service is started/stopped.
2037 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2038 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2039 in util/yc.tcl. The auto-generated C code structures are, in a few
2040 cases, incompatible with the old decoders. There are differences in the
2041 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2042 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2043 The preprocessor variable ASN_COMPILED is defined when the compiled
2044 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2045 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2046 wish to use the old encoders/decoders you can specify --disable-yc
2049 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2050 version so that it supports both new - and old version of DB Update
2052 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2053 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2054 change. The name parameter can be set to 0 in which no name is specified
2055 for the construction. The macros odr_implicit and odr_explicit sets name
2056 parameter to zero for the construction involved. New macros
2057 odr_implicit_tag and odr_explicit_tag are similar to the others,
2058 except that a name parameter is added. For programmers' that don't use
2059 ODR they probably only need to change the call to z_APDU and z_External.
2061 Added access control facility by interfacing the TCP wrapper library.
2062 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2063 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2064 name of the daemon and enables the access control as specified in
2065 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2067 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2068 den Dool <H.M.vdnDool@kub.nl>.
2070 Added reference ID parameter to most functions in server API - refer
2071 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2073 Changed name of ccl library to libccl.a (was ccl.a).
2075 Fixed bug in decoder for Explain (Category TargetInfo).
2077 Added support for GNU readline in client. Thanks to Jacob Poulsen
2078 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2080 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2081 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2082 IMPLEMENTATION! This change was made to the development version before
2083 the ZIG decided to retract the amendment. If any users MUST be
2084 compatible with the original Update definition, PLEASE CONTACT US, and
2085 we will include a separate definition corresponding to the old Update
2086 ES. Note that because of the change to the ASN.1 of the
2087 TaskPackageRecordStructure we cannot define a single structure that
2088 will support both versions.
2090 * Added const modifier to buffer parameter for some ODR/BER encoding
2091 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2092 completeWAIS, odr_dumpBER.
2094 Fixed bug in client.c which caused a crash when a scanResponse didn't
2095 contain positionOfTerm.
2097 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2098 * will cause an error in a client if a non-YAZ target sends both a
2099 * list of Scan entries and non-surrogate diagnostics.
2101 Retrieval module enhancements. Tag sets may be typed in the reference
2102 to it. From the .abs-file the "tagset" directive takes a third optional
2103 integer type for the tag set referenced. From a .tag-file the "include"
2104 directive takes a third optional type as well. The old "type" directive
2105 in the tag set itself is still recognized but acts as the default type
2108 Backend interface change. Individual Scan terms returned from bend_scan
2109 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2110 in include/backend.h.
2112 Retrieval module enhancements. Multiple tag sets and attribute sets may
2113 be specified in abstract syntax specs. Revised the error/warning for
2114 logging messages reported by the retrieval module when reading the
2117 Object Identifier system (oid_..) changed. The API is backwards
2118 compatible but the oid-routines now allocates new OID's when needed.
2119 Raw OID's may be specified in oid_getvalbyname.
2121 YAZ now uses GNU configure to generate Makefile(s).
2123 * Minor changes in some of the member names of DeleteResultSetRequest and
2124 DeleteResultSetResponse. See include/proto.h.
2126 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2127 and added member 'languages' in TargetInfo (which was missing).
2129 Changed the way attribute sets are handled in the retrieval
2130 module. These are now cached, just like the abstract syntaxes
2133 Changed YAZ so that it links with compiled ASN.1.
2135 Added Explain-schema definitions and mapping routines. The following
2136 Explain categories have been implemented: AttributeDetails,
2137 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2139 Fixed minor bug in Windows version of Server Library.
2141 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2143 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2145 Added EXTERNAL: UNIverse Resource Report (non-standard).
2147 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2148 ENUMERATED and SET OF.
2150 * Added 'const' to some of the char pointer arguments for the
2151 functions, data1_read_node, data1_getelementbytagname,
2152 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2155 Fixed bug in data1_insert_taggeddata - the last_child member of
2156 parent wasn't initialised.
2158 * Changed data1_read_record and data1_read_node so that the supplied
2159 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2160 doesn't refer to any parts of the "SGML"-buffer.
2162 Fixed bug in server library (Windows version of statserv_remove).
2164 * Changed code so that it compiles as C++. The type definition
2165 of Odr_fun which is a member of Odr_arm was changed. The result is,
2166 that an explicit typecast is needed for the fun pointer when
2167 using Odr_arm - as in:
2168 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2170 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2172 Implemented the new structured date and time definition as approved
2173 by the ZIG. Added schemaId element to the specificTag in Espec-1
2174 (also approved at the last ZIG). Thanks to RVDM.
2176 Added some Object identifiers (RVDM).
2178 Changed the Update Extended Service (RVDM).
2180 Added command "refid" to client which specifies referenceId for
2181 the following requests.
2183 Implemented extended service handling for server. See ztest.c
2184 for an example as well as backend.h. New handlers are registerd
2185 in the Init handler.
2187 * Changed interface for sort in server.
2189 Added new members to statserv_options_block. It allows a server
2190 to read options from another source than just the command line. Thanks
2191 to Charles Woodfield.
2193 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2194 renamed to zboolean. Some C++ compilers complained about the name.
2196 Minor changes to gils.abs. Added index 's' (sort) on title
2197 and date/time-last-modified.
2199 --- 1.4pl2 1998/1/30
2201 Fixed bug in server library regarding inetd mode (-i). This bug
2202 was introduced by release 1.4.
2204 --- 1.4pl1 1998/1/29
2206 Added sort facility in client and backend server interface.
2208 Fixed problem with dependencies in Makefile(s).
2210 Fixed bugs for encoders/decoders of extended services and
2213 Implemented sub-tree feature for schemas. Sub-trees are
2214 referenced in *.abs-files. See explain.abs for an example
2215 of the use of this feature.
2217 Modified bib1.att; local attributes for ANY didn't include
2218 ANY itself (only affects use of the retrieval module).
2220 Fixed bug in plain SGML reader in function data1_read_node:
2221 tags with prefix "var" was incorrectly interpreted as variants.
2223 Added feature "sub-schemas" to enable references to - and definitions
2224 of - group of elements.
2226 * Removed member parent from type data1_element (in data1.h).
2228 Implemented function odr_nullval() that returns the value of
2231 * Removed member num_children from data1_node (in data1.h).
2233 Made NT service interface part of the server library. The
2234 function statserv_main uses the NT service when required and
2235 calls the statserv_start / statserv_close routines.
2237 Routine zget_SearchRequest and zget_PresentRequest fills
2238 resultSetName/Id member with "default" instead of "Default".
2240 Fixed memory leak in server. Request queue member wasn't freed.
2242 Fixed nmem_exit so that memory is freed.
2246 Revised the CCL parser utility to be thread safe.
2248 Added function, oid_ent_to_oid, to replace the function
2249 oid_getoidbyent, which is not thread safe.
2251 * Added nmem_init and nmem_exit to initialize and release
2252 NMEM resources. Function nmem_init should be called once in the
2253 initial thread before NMEM/ODR is used. statserv.c and client.c
2254 have been changed accordingly. The change was necessary to make
2255 NMEM thread safe. The NMEM memory pool is shared amongst threads
2256 in a process. Unix-based applications will still work fine without
2259 Added NT Services interface for the the Z39.50 (statserv) Server.
2260 Refer to the ztest.c source on the usage.
2262 Windows 95/NT port using MSVC5.0. Project files are included in the
2265 * Defined new 'global' handle for the retrieval (data1) system. The
2266 new handled, data1_handle, describes the state of the data1 system.
2267 This handle is passed as first argument to virtually all
2268 data1 related routines. The functions data1_create and data1_destroy
2269 creates and destroys a data1 handle respectively.
2271 Added ODR encode stream member to all backend request structures
2272 init, search, scan etc. This stream should be used to allocate all
2273 memory used for the response when thread safe operation is needed.
2275 Changed the comstack utility, cs_addstr, to be thread safe. The
2276 returned hostname string returned by the function is now part the
2279 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2280 function. The cs_straddr takes a COMSTACK handle as argument, so this
2281 function must be used after cs_create and before bind/connect.
2282 This function is thread safe.
2284 Moved test server to 'ztest' directory - generic server code still
2285 in 'server' directory.
2287 Made prefix query (pquery.c) utility thread safe.
2289 Added new function modifier YAZ_EXPORT to 'export' public DLL
2290 functions when using windows (see include/yconfig.h).
2292 Added definitions to the OID database (util/oid.c) (RVDM).
2294 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2296 Added call to ccl_rpn_delete in client program.
2298 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2299 release of RPN structure.
2301 Added support for C++, headers uses extern "C" for public definitions.
2302 With input from RVDM.
2304 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2305 Thanks to Ronald van der Meer (RVDM).
2307 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2309 Added support for private extensions to the OID database
2310 (oid_setprivateoids()). Thanks to RVDM.
2312 Added optional, physical ANY (key replication)
2314 Fixed null-reference problem in GRS-1 output filter.
2316 Proximity operator added to Prefix Query Format (PQF).
2318 In test client command "base" accepts multiple databases.
2320 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2324 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2326 Smallish bug-fixes in the new encoders/decoders (explain).
2328 Bug fixed in DeleteRequest.
2330 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2332 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2334 Added SOIF syntax (using private OID for now) to retrieval module and client.
2336 Added Update extended service.
2338 Added SearchResult-1 additional info structure.
2340 Added optional CCL (ISO8777) interpreter as separate module. Available
2343 --- 1.2 1996/6/10 (1st anniversary release)
2345 Added Summary record syntax. Lightly tested.
2347 Added OPAC record syntax. Untested.
2349 Added ResourceReport service encoders/decoders. Untested.
2351 Fixed bug in z_Unit - wrong tagging on unitSystem.
2353 Fixed bug in the DiagRecs decoder.
2355 Added options for max PDU size and session timeout to frontend-server.
2357 Added documentation of query-language parsers and other supporting utilities.
2359 [frontend-server] Added Attribute set to the bend_scanrequest API.
2361 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2362 surrogate diagnostics were generated.
2364 [retrieval] Allow multiple local values for attribute.
2366 [retrieval] Allow multiple attributes per element in .abs files. index type.
2368 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2370 --- 1.1pl2 1996/4/10
2372 Minor changes, mostly specific to Zebra's requirements (retrieval)
2376 Repaired bug in frontend server when running multiple listening
2377 endpoints in dynamic mode.
2379 z_External() now won't break if a known, ASN.1 value comes encapsulated
2380 in an octet-string. The value will pass through unmodified in an Odr_oct.
2382 Added a bit of code to the demo client to decode & display
2383 ASN.1-structured records represented in the octet-aligned branch of
2384 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2386 Added z_ext_getentbyref() to the ASN module. Doc updated.
2388 * Completed the SCAN definition in the ASN module. This may break SCAN
2389 code based on older YAZ-versions at compile-time. The fix is easy -
2392 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2393 under the SCAN definition. Remember to initialize this, server-people.
2395 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2396 that this does not extend to ODR and ASN.
2398 Comstack allows insertion of established socket (primarily for
2399 inetd-operation of servers). Doc updated.
2401 Front-end server can now start from the inetd in TCP mode. Doc
2404 --- 1.0pl4 1996/1/24
2408 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2409 the rank and record number.
2411 Adjustments to the frontend server.
2413 Fixed diagnostic BER dumper. It ignored the file argument.
2417 Various changes to retrieval module.
2419 Changed the union discriminators of the protocol files from enums to
2420 ints paired with #defines.
2422 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2425 *Changed operator in the RPN structure to 'roperator', again to avoid a
2428 Fixed problems in Explain decoders/encoders.
2430 --- 1.0pl2 1995/12/6
2432 Memory bug in log module fixed.
2434 --- 1.0pl1 1995/12/5
2436 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2438 Bug in Explain DatabaseInfo module fixed.
2440 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2444 The shift to v1.0 signals that we now consider the *core* functionality
2445 of YAZ reasonably stable (the core being more or less equivalent to
2446 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2447 tested (Explain not at all - though that will happen soonish).
2449 Minor changes to code to support Windows port.
2451 Various minor changes after we're getting to use GRS-1 & co. more.
2453 Added Espec-1 format.
2455 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2456 of the protocol and it cannot be selected when encoding (maps into 'string'
2457 when decoding). Needed to talk to some servers.
2459 Demo client can request simple element set names.
2461 Added Diagnostic Format encoders/decoders.
2463 Added simple Close handling to frontend server (no hooks for resource
2464 reporting yet), and demonstration client.
2466 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2468 --- 1.0b3 1995/08/24
2470 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2471 handled incorrectly when records were requested in the searchResponse. This
2472 will only affect you if you use the frontend-server.
2474 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2475 Test-client will ask for and print GRS1. Ztest will return dummy records
2478 Added Explain encoders/decoders to the service-level API. Untested.
2480 Added Extended Services: Item Order encoders and decoders to the Service-
2481 level API. Untested. We could use a recent copy of the pertinent bits
2482 of the ILL protocol to add those bits.
2484 Added diagnostic format 1 encoders/decoders to the service-level API.
2487 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2488 odr_cons.c, which causes a more correct output.
2490 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2491 was always set to 0 when no records were requested in the searchRequest.
2493 * Added better external-handling. This shouldn't harm old code that
2494 *encodes* externals. It can break code that looks for a
2495 'single-ASN1-type' representation, since those types that are known
2496 are now decoded immediately. Look at the SUTRS sample code in
2497 seshigh.c and client.c. Documentation updated.
2499 Handling of structured records in bend_fetchresponse. Length -1 marks
2500 structured record, type is deduced from format field.
2502 --- 1.0b2 1995/06/27
2503 Fairly quick maintenance release to add SUTRS support.
2505 Fixed handling of SUTRS records in the demonstration client.
2507 * Added format field to the bend_fetchrequest and bend_fetchresponce
2508 structures of the backend API (frontend server). When the record is
2509 returned, the value of the format field is mapped to an OID. The
2510 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2511 of the record. The special value VAL_NONE in the bend_request means
2512 that no specific format was requested by the client. Documentation
2513 updated accordingly. Test server (ztest) will return a fixed dummy
2514 SUTRS record if your client requests SUTRS.
2516 Documentation updated accordingly.
2518 You can now set external libraries and RANLIB support in the top-level
2522 First public release.
