3 Function yaz_xml2query allows a diagnostic element in the PQF XML
4 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
5 code and additional info respectively.
7 The BER BOOLEAN is now the integral type Odr_bool which still happens
8 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
9 typedef'd to Odr_int. This is still an integral 'int', but it may be
10 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
11 ASN-1 compiler as well as programs has been updated to use the new types.
15 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
16 only the bibliographic record was rendered. For type=opac, an OPAC
17 record is only returned if it is present.
19 iconv: small fix for encoding of advancegreek.
21 yaz-client: avoid double display of SRU/SRW records (bug #2798).
23 yaz-client: option auto_reconnect=on really reconnects.
25 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
27 server: avoid null ptr ref for for yaz_poll errors.
29 build: fix RPM build for RHEL 5.3.
31 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
35 Fixed bug #2709: TCP connect returns Invalid argument.
37 Fixed compilation for mingw.
39 Honor charset for raw records (ZOOM_record_get).
41 Fixed use of errno for threaded mode that was seen on Solaris 10.
43 Fixed argument passing with blanks in value for Windows Service.
45 Disable YAZ' own log rotate by default (no 1 GB limit).
46 The variable l_max_size which specifies the log file limit is set to 0
47 (DISABLED): This is due to the fact that YAZ is most often deployed using
48 logrotate. Also YAZ can not perform log rotate because of unsufficient
53 List supported encodings in man page for yaz-iconv.
55 Fixed missing SSL libs for --libs output
57 Re-established OID record syntax application-xml. Nobody should use it
58 but we don't want to change soname because of this symbol being absent.
62 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
64 Added member named_result_sets for init handler struct for the GFS. This
65 allows a server to disable named result sets.
67 Removed OID record syntax application-xml.
69 Added support for rule-based transliterator for ICU wrapper of YAZ.
71 Fixed bug #1902: yaz-icu XML output.
73 Make YAZ checks Emacs friendly.
75 BITSTRING value shows value. Bug #2346.
77 ISO2709 decoding: skip control characters from indicator data.
79 Omit sort key by default in yaz-icu's output.
81 Allow combined single char options (again) for YAZ' options function.
83 Utility yaz-marcdump got option to display YAZ version (-V).
85 Allow YAZ to use ICU 3.4.
87 Added new ICU test case which illustrates removal of diacritics.
91 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
95 For configure, using option --without-xml2 also disables Libxslt/Libexslt
98 Fixed bug #2352: yaz-marcdump crashes for certain record.
100 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
102 Added support for Danmarc2 to UTF-8 conversion.
104 Added support for ISO5426 to UTF-8 conversion.
106 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
107 implementation version.
109 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
111 --- 3.0.38 2008/11/10
113 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
114 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
116 ZOOM C now interprets databaseName option for ZOOM connection as path
119 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
121 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
123 Dummy Libxml2 types no longer defined in headers of YAZ'.
125 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
128 --- 3.0.36 2008/09/26
130 Various ODR chapter fixes.
132 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
134 Added missing source for Windows compilation, mutex.c.
136 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
138 For SRU connections in ZOOM all records up to "count" are now fetched.
140 Fixed crash in generic frontend server (and yaz-ztest) which occurred
141 in Windows due to bad error handling for Libxml2.
143 Added facility for sending arbitrary records (ASN.1 any) using
144 ZOOM C's Extended service update. Patch by Sam Reynolds.
146 New options for ZOOM C's connection, logapdu which makes ZOOM log
149 --- 3.0.34 2008/06/18
151 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
153 --- 3.0.32 2008/06/12
155 Fixed memory violation that could occur when decoding UTF-8. This bug
156 was only present in 3.0.30 of YAZ.
158 --- 3.0.30 2008/06/06
160 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
161 GNU TLS is used by default (if found).
163 yaz-ztest returns OPAC records if a client asks for OPAC.
165 Improved speed of MARC-8 encoding.
167 Added support for lossy and loss-less MARC-8 encoding.
169 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
171 Added new Windows Service wrapper (sc).
173 yaz-client's itemorder command may now send a file.
175 Fixed yaz-marcdump to allow the use of NS prefix for record element.
177 Added new function yaz_log_xml_errors.
179 Allow (but warn) unknown XML attributes in MARCXML parsing.
181 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
183 The UTF-8 to MARC-8 conversion now uses a different set of characters
184 for Greek symbols. Bug #2120.
186 --- 3.0.26 2008/02/21
188 Added yaz_daemon (daemon.h).
190 Fixed bug #2068: pkg-config trouble
192 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
194 --- 3.0.24 2008/01/28
196 Document --with-xml2 option.
198 Added OPAC XML XSD (etc/opacxml.xsd).
200 Allow glob mask for name attribute in retrieval element for the
201 generic frontend server's retrieval facility.
203 Changed yaz_poll_poll to return yaz_poll_except for all returned events
204 except POLLIN/POLLOUT.
206 Fixed error handling in cs_listen. Bug #2037.
208 --- 3.0.22 2008/01/20
210 Fixed version in yaz/yaz-version.h.
212 Fixed bug #2027: Crash when closing connection.
214 Changed configure so that ICU support is only enabled if only ICU
215 and Libxml2 is available (because the ICU chain is XML based).
217 --- 3.0.20 2008/01/15
219 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
220 is built. Only this DLL depends on the ICU runtime.
222 yaz-ziffy is no longer part of YAZ. It is distributed separately by
223 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
225 Changed license of CCL module to 'Revised BSD'. After consultation with
226 remaining members of the original EUROPAGATE consortium, we are re-issuing
227 the CCL module without a separate license. The software was developed by
228 Index Data as part of a research project. The special license was included
229 to help feed usage information back to the project consortium to support
230 project evaluation. At this time, the project consortium has long-since
231 disbanded, and the majority of the original principals have retired. At the
232 same time, we have significantly modified the software during the following
233 years, to the point where very practically no original code remains. To
234 simplify re-use of the software, we have contacted those members of the
235 consortium who could be reached, and agreed to re-issue the module as a
236 proper part of the YAZ package.
238 Tcl scripts uses /usr/bin/tclsh as preferred shell.
240 CQL closer to being version 1.2 compliant. CQL also allows free-form
241 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
244 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
245 bug could make Extended services handling crash in the ZOOM layer. This
246 bug was only present in YAZ 3.0.18.
248 --- 3.0.18 2007/12/19
250 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
253 yaz-marcdump reads and writes collection wrapped records.
255 Handle OPAC for record conversion module.
257 Fixes for ICU wrapper.
259 Allow ICU libs to be controlled with --with-icu .
261 --- 3.0.16 2007/11/12
263 Added yaz_poll which is a wrapper for select/poll. When poll is available
264 and non-buggy, it is used, by yaz_poll . This allows more than 1024
265 sockets to be in use.
267 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
268 functionality through an XML based configuration (ICU chain). This system
269 is useful for search facilities such as Pazpar2 and Zebra that needs to
270 perform tokenization of indexed material. The ICU code in a separate
271 library libyaz3_icu.a.
273 Added HTTP tunnel facility for COMSTACK, bug #1752.
274 This is a facility that allows a Web proxy, such as squid, to tunnel
275 Z39.50 traffic. This facility is "transparent" to must applications
276 using YAZ. It's enabled by using pseudo transport connect: followed by
277 the proxy address, followed by command, then follwed by he regular
278 "virtual" addresss. For example,
279 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
281 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
283 --- 3.0.14 2007/09/21
285 Fixed bad memory reference in ZOOM_record - cuased by member not being
286 initialized. This was a problem only in YAZ 3.0.12.
288 Fixed bug in conversion from MARC to XML: Non-XML characters in control
289 fields were not removed.
291 Changed the way C code is generated from codetables.xml. Made a MARC-8
292 conversion trie for each characterSet section rather than codeTable.
293 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
294 of codetables.xml from Larry Dixson, LOC. Bug #1464.
296 --- 3.0.12 2007/09/12
298 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
299 from ZOOM_record_error).
301 ZOOM C function ZOOM_record_get returns record schema for type="schema".
303 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
305 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
307 Better SRW-to-Bib-1 diagnostic mapping.
309 ZOOM C and yaz-client announces SRU version 1.2 by default.
311 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
314 Fixed in yaz_sru_decode to allow other version than 1.1.
316 --- 3.0.10 2007/08/22
318 Added support for SRU scan for ZOOM.
320 Added support for the use of the older versions or Extended Service
321 Update in ZOOM. To faciliate this, an option "updateVersion" may be
322 set to the version , 1=first, 2=second, 3=third. The third version is
323 what ZOOM C has used so far. And that, obviously, is the default.
325 Added support for CCL queries in Z39.50 queries sent to the GFS (and
326 therefore in Zebra and in SimpleServer-based applications). The new
327 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
328 qualifier file used to transform incoming CCL queries into Type-1 RPN,
329 which is passed into the back-end search callback function.
331 Added support for HTTP Basic authentication in clients: the SRU/W
332 codec encodes the username/password elements of the PDU structure
333 appropriately, and these may be set using the "user" and "password"
334 options in ZOOM-C applications (the same options that are used for
335 Z39.50 authentication).
339 Fixed bug #1208: SSL appears to be broken in ZOOM.
341 Fixed bug #1206: Libxml2 include path weirdness.
343 Added oid_name_to_dotstring.
345 Allow elementSetName to be specified for ZOOM C record update.
347 Allow waitAction to be specified for ZOOM C based for Extended Services.
349 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
350 syntax OID. Bug introduced in YAZ 3 series.
352 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
356 Fixed bug #1157: yaz-client does not read .yazclientrc from current
357 directory. yaz-client now reads commands from file given by option -f
358 if specified; then tries to read .yazclientrc in current directory.
359 Failing that, it reads .yazclientrc from user's home directory.
361 Added support for correlationInfo Note and ID for Record Update via
364 Added yaz-client command querycharset which specifies character set for
365 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
366 (termListAndStartPoint).
368 Charset ISO5428:1984 is an alias for ISO5428-1984.
370 Implemented a way to perform scan in a result set using Z39.50. This
371 is achieved by attaching the result set name in the characterInfo
372 (type InternationalString) of OtherInformation in the Scan Request PDU.
373 The result set is identified in the otherinformation by the new OID:
374 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
375 This allows for scan in result set and faceted search . Zebra did some
376 of this in the APT term using attribute type 8 and value being result
377 set. Using the OtherInformation approach for this is cleaner and easier
378 to work with in proxies and the like. This facility can be used in
379 yaz-client using new command setscan which takes a result set as first
380 argument, start position (APT) as second.
382 Changed decoding of SRU XML packed records to deal with servers that
383 have recordData with XML data with multiple root nodes. Also make
384 comparison for recordPacking case insensitive. Again, one server
385 returns "XML" where others return "xml".
387 For SRU responses allow Content-Type application/xml as well as text/xml.
391 Fixed bug in character set conversion of BER strings. Bug introduced
396 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
398 For OID class, use oid_class consistently.
400 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
403 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
404 character set for bibliographic information interchange". By Giannis Kosmas.
406 Added documentation on new OID API.
410 Changes to generic frontend server interface: added new member
411 'query_charset' for bend_initrequest structure. A backend init handler
412 should set this member to its native character set for query terms.
413 When defined, the frontend server logic will announce this character set
414 to a client if the negotiationModel bit is set by the client. All server
415 implementors are encouraged to specify this. If a backend server does not
416 specify this a warning is issued using yaz_log(YLOG_WARN,..).
418 Added CCL utility to remove terms (stop words) from resulting RPN
419 tree. This is handled by functions with prefix ccl_stop_words_ .
421 New ZOOM C option, "rpnCharset", which allows client-side conversion of
422 terms in RPN queries.
424 Clean-up the CCL API. Moved some internal structures from ccl.h to
425 private header cclp.h. Changed ccl_parser_create so that a Bibset must
426 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
427 This is replaced by ccl_parser_find_str which takes a string instead.
429 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
430 libyaz.la is the core of YAZ except the generic frontend server and
431 does not depend on POSIX threads anymore. libyaz_server.la is the
432 generic frontend server facilities and uses POSIX thread functionality
433 if available. The libyaz.la no longer depends on POSIX threads because
434 the number of global structures is limited. NMEM no longer re-uses blocks
435 between threads ; it simply free's memory immediately but allocates in
436 "large" chunks as usual. We don't expect any performance penalties
437 because of this. The yaz_log system is still using a global log_level so
438 caution must be taken when modifying it with yaz_log_init_.. +
439 yaz_log_mask_str. This, however, should not cause any trouble because
440 these functions are called during initialization of application code
441 anyway. `yaz-config --libs server` returns libs for server applications;
442 `yaz-config --libs` returns libs for non-server applications.
444 New OID database - with public definitions in oid_db.h. Removed old OID
445 database including the head oid.h and definitions such as enum oid_value
446 and struct oident. The new OID database uses the same string names as
447 before but the 'protocol' is gone. There are now only two representations
448 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
449 converts from string to OID; functions with prefix yaz_oid_to_string
450 converts the other way.
452 Change to emit_term() in CQL-to-PQF query translation: when a term has
453 the /regexp relation modifier, do not process it for leading and
454 trailing "^" and "*", which have quite different meanings in regular
457 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
458 write handlers no longer carries a 'last' parameter. This will make
459 yaz_iconv flush "less" characters. A flush is performed by call to
460 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
462 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
463 removed, because function yaz_query_to_wrbuf does the same.
465 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
466 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
468 Deprecated MARC utility functions removed.
470 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
473 Branch split: YAZ_2_1_55_branch
475 --- 2.1.54 2007/03/16
477 Fix to ZOOM-C so that transparent reconnection is properly handled on
478 connections that are in asynchronous mode.
480 Fixed compilation on OpenBSD 4.0.
482 Large strings in GRS-1 records are now properly displayed in yaz-client.
484 Added character conversion support for "advancegreek"; based on patch from
487 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
488 sequence is met. Before the error was not set so it would be unknown.
490 Adjust yaz-marcdump MARC reader so that it skips until record separator
493 --- 2.1.52 2007/03/07
495 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
496 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
497 fd_set structure used as a bitmask for the FDs to be selected on.
499 Using ACX_PTHREAD macro to check for POSIX threads.
501 Fixed have-vsnprintf check.
503 --- 2.1.50 2007/02/23
505 Fixes for configure on BSD. Bug #900.
507 Added snprintf/vsnprintf wrappers for systems that don't have
508 limits (heavens forbid).
510 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
511 created before all previous tasks were completed and removed from the
512 task queue, the new task could be removed by a mistake.
514 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
516 Implemented pass-through CQL-to-PQF conversions. Bug #861.
518 Fixed bug #832: Problem with MARC/charset in yaz-client.
520 Fixed bug #668: save command line history for yaz-client.
522 Fixed bug #830: pkg-config support.
524 --- 2.1.48 2007/01/23
526 Extended ZOOM result set options with two options that may be read by
527 a client: resultSetStatus and presentStatus with values as specified for
529 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
531 Fixed bug #827: Using SSL fails on Debian etch.
533 Fixed bug #826: Weird looking chars for set of MARC records.
535 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
536 that is treated as an ItemOrder with itemRequest being an XML document
537 external. The value of "doc" is the content.
539 Extended the GFS search facility. New member of bend_search_rr
540 'estimated_hit_count' signals that hits is known to be an estmate
541 (higher or lower than real hit count). New member 'partial_resultset'
542 signals that the search was partial (hit count is lower or equal than
543 real hit count). For Z39.50, the information is stored in resultSetStatus
544 member of SearchResponse APDU. For SRU, the information is signalled
545 via SRU diagnostic 59: "Result set created with valid partial results
548 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
550 --- 2.1.46 2007/01/13
552 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
554 Added ZOOM_connection_peek_event.
556 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
557 the following new functions:
558 ZOOM_event_nonblock, ZOOM_connection_process,
559 ZOOM_connection_get_{socket,mask,timeout},
560 ZOOM_connection_fire_event_{timeout,socket}.
561 The existing blocking event handler, ZOOM_event, is a wrapper for the
562 + blocking ZOOM_event_sys_{poll,select}.
564 Implemented function ccl_xml_config which parses XML version of CCL
565 configuration (bug #798).
567 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
569 Added timings utility (yaz/timing.h)
571 --- 2.1.44 2007/01/03
573 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
576 Fixed bug #779: Rotation of apdu.log fails.
578 Fixed for character set conversions:
579 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
580 Honor G1 set in MARC-8 decoding.
582 --- 2.1.42 2006/12/17
584 Fixed bug #775: char conversion does not handle Alternative UTF-8
587 Implemented function yaz_marc_read_line which parses MARC line format
588 records. There is a wealth of formats out there. So far, this function
589 reads line records produced by yaz_marc_write_line.
591 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
592 more generic and easier to remember(!) options: -i format and -o format
593 which specifies input format and output format respectively - where
594 format is one of "marc", "marcxml", "line", "marcxchange".
596 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
597 does not print anything except warnings for records.
599 For yaz-marcdump, added support for MARC split into files (-s) with a given
602 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
603 spec, at http://www.loc.gov/standards/sru/record-update/
604 This has changed the binary layout of the following structs:
605 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
606 bend_update_rr . Patch by Ko van der Sloot.
608 Added GFS utility function bend_assoc_is_alive which returns 1 if
609 association is still alive (client is connected); 0 otherwise (client
610 closed connection). This allows busy servers to stop working for
613 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
614 been a separate piece of software. This version of ziffy has been modified
615 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
617 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
619 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
620 Client code may now interrogate options such as "init_opt_sort" to
621 find out whether the server claims to support various options.
623 --- 2.1.40 2006/11/27
625 Added utilities yaz_{set,get}_esn to set/get element set name from
628 Removed the build of libyazthread.la. The libyaz.so is the threaded version
629 of YAZ and has been so since YAZ 2.1.10.
631 Implemented ZOOM_record_error which returns error information for
632 record (surrogate diagnostic).
634 --- 2.1.38 2006/10/31
636 Updates for SRU Update by Ko van der Sloot:
637 1. Changed name from "operation" to "action"
638 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
639 versions in the code, marked as 'backward compatible'.
640 3. Added diagnostics for SRU Update.
642 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
644 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
646 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
648 For GFS, fixed problem with SRU diagnostic 'First record position out of
649 range' being issued for 0 hits.
651 zoomtst10 part of Windows Build.
653 --- 2.1.36 2006/10/13
655 Implemented yaz_filepath_comp which splits a path into file path
656 components (required by Zebra 2.0.3+).
658 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
659 BSD inspired license until now so this should not have any real impact on
660 anybody. See http://www.opensource.org/licenses/bsd-license.php
662 Fixed bug #687: Missing log lines.
664 Fixed bug #678: CQL to PQF translation does not preserve double-quote
667 Fixed bug #689: SRU diagnostics to be added.
669 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
670 whether a connection is idle (no more work do do).
672 --- 2.1.34 2006/10/04
674 Change type of optval from long to int for invocation of setsockopt with
675 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
677 Added support for specifying the max log file size for the Generic
678 Frontend Server. The size is given with option -r.
680 --- 2.1.32 2006/09/21
682 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
684 --- 2.1.30 2006/09/17
686 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
689 Fixed bug in Generic Frontend Server that could cause a server to stop
690 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
692 For the generic frontend server, the maximum record size is used as maximum
693 size of incoming packages (SRU + Z39.50). The value until was previously
694 only used in Z39.50 Init negotiation and, later, in a session controlled
695 sizes of records returned. This is controlled using -k option. It can be
696 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
698 --- 2.1.28 2006/09/04
700 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
703 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
705 New option for yaz-marcdump -lpos=value which allows setting a portion
706 of MARC header to a certain value.
708 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
710 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
711 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
713 --- 2.1.26 2006/08/15
715 Fixed problem with SRU mode type (soap, get, post) for yaz-client
718 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
720 --- 2.1.24 2006/08/08
722 Fixed MARC ISO2709 encoding routines to deal with character set
725 Minor changes to GFS logging. Database included in search request log
728 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
729 cached/multiple records.
731 Shared libraries are built by default on Unix+configure.
733 Changed cql2pqf transformation to use a different evaluation order. The
734 new order is: always, relation, structure, position, truncation, index
735 and relationModifier. Old order was: always, relation, relationModifier,
736 structure, index, position, truncation. Note that the the latter ones
737 override former ones for identical attributes.. The new scheme means that
738 it is possible to override any existing attribute with a relationModifier.
739 And also that it is possible to override everything for the index rule
740 (except the ones listed in relationModifier). No order is perfect but this
741 one, we believe, covers more real cases.. The "always" should have been
742 called "default", since the attributes there can be overridden with all
745 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
746 compilation phase, but also for yaz-config --cflags output. This allows
747 us to have public headers with Libxml2 stuff in them . It should also,
748 eventually, make Libxml2 checks redundant in packages using YAZ, such
751 --- 2.1.22 2006/06/15
753 Changed SRU update structure bend_update_rr so that SRU diagnostics are
754 stored in uri, message and details.. Previously diagnostics were stored
755 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
756 compatibility.. but he's probably the only one affected, so.
758 Added support for CCL, compiled on the client side, in ZOOM-C. This
759 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
760 input; the resulting query objects can be used for for searching with
761 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
763 YAZ' configure searches for OpenSSL by default.
765 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
766 SL_CTX_use_certificate_file. See
767 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
768 for more info. Thanks to Ko van der Sloot.
770 --- 2.1.20 2006/06/02
772 Bug #600: SRU GET, POST support for yaz-client. Introduced
773 command 'sru' which selects method SOAP/GET/POST.
775 Allow missingValueAction to be specified for the sortspec string -
776 function yaz_sort_spec. By default, the missing value action is null.
777 Use ! to specify "abort". Use = followed by stringvalue to specify default
780 Ensured that Present-handler (if defined) is called in GFS before any call to
781 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
782 searchRetrieve requests.
784 Documentation for YAZ is now based on the Docbook XML/XSLT using
785 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
786 is no longer depending on jade/openjade or docbook-to-man scripts.
787 PDF is no longer part of the distribution - but can optionally be
788 made using DSSSL/jadetex or FOP.
790 Added retrieval handling support in Generic Frontend Server to support
791 conversion between MARC/XML as well as XSLTtransforms. See
792 etc/yazgfs.xml for an example.
794 Added Authentication support to Generic Frontend Server in SRU
795 mode. Authentication using HTTP Basic is supported, as is the use
796 of 'x-username' and 'x-password' parameters in the request itself.
798 Added support for a new character set MARC8s identical to MARC8 except
799 that it converts combined characters to single Unicode characters in the
800 Latin-1 range (when possible).
802 --- 2.1.18 2006/04/24
804 ASN.1 compiler 0.4: generates brief Doxygen file header for
805 generated .h/.c files.
807 Utility yaz_iconv now supports conversion to MARC-8.
809 New facilities for the MARC module. The reading - and writing of
810 content are separate methods for the yaz_marc_t handle. The following
811 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
812 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
813 format). Write functions have prefix yaz_marc_write_.. The existing
814 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
815 available. Removed support for OAI-MARC and simplexml (not the
816 simplexml from PHP5).
818 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
819 to be returned for this connection.
821 --- 2.1.16 2006/03/31
823 Allow multiple languages and charsets to be specified with
824 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
825 negcharset iso-8859-1,utf-8
827 Translation of proximity nodes from CQL into PQF now works.
829 Moved to automake 1.8, 1.9.
831 Added function yaz_log_set_handler which allows a log handler to be
832 installed. This handler will be called for all log messages. Output
833 to file is also produced; but that can be disabled by passing NULL
834 fname to yaz_log_init_file.
836 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
838 For SRW (including GFS), accept application/soap+xml as content-type
841 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
842 produces NO stylesheet reference even if a default stylesheet is specified
845 --- 2.1.14 2006/03/14
847 Updated Windows package to include yazd.dll + yazd.lib for the
848 Development component.
850 If the environment variable YAZ_LOG is set, then it is used as a
851 string indicating the default level of logging to use if not
852 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
853 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
854 used as before. So, for example, to omit warnings from YAZ logging,
857 cql_transform() now map structure and other attributes before indexes,
858 so that index-specific structures and other attributes can override
859 defaults. So now a combination of mapping specifications such as:
861 index.dc.date = 1=date-modified 4=5
862 does the right thing.
864 cql_transform() now also respects the "always" mapping specification,
865 which establishes an initial set of attributes to be used for all
866 terms except where overridden by more specific attributes associated
867 with the index, relation or modifier.
869 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
870 which mode to use; one of "post", "get" or "soap" (SRW, default).
872 Fixes for yaz_iconv routines: changed trie-based character set conversions
873 to use only non-negative values for bit fields due to Sun's C compiler not
874 supporting negative values.
876 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
877 sequences where not read correctly. Fix by Rustam Usmanov.
879 Updated win/makefile to use options, settings which makes things
880 compile with VS C 2005.
882 --- 2.1.12 2006/02/01
884 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
886 In ZOOM socket code, use select instead of poll on MacOSX.
888 ZOOM-C now support client-side compilation of CQL into RPN that is
889 sent to the server, enabling CQL to be used against all Z39.50
890 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
891 ZOOM_query object, and submit it using ZOOM_connection_search().
892 The CQL-to-RPN translation uses a configuration file, the name of
893 which must be specified in the Connection's "cqlfile" option.
895 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
896 function, which takes as its start-term parameter a ZOOM_query object
897 (which may have had either CQL or RPN set into it).
900 --- 2.1.10 2005/11/29
902 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
903 GFS to support this as well. Backend handler, bend_srw_update, does the
904 update work. Code contributed by Ko van der Sloot.
906 Allow retrieval of Search Result-1 information in ZOOM by the use of
907 options that are attached to a result set. ZOOM documentation updated
910 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
911 UTF-8 conversion. Patch by Raj Patel.
913 Added option -m to GFS to control formatting of timestamps in log file.
915 Added 'exit' as synonym for 'quit' in yaz-client
917 Added support for specifying SRW resultSetId + resultSetIdleTime in a
918 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
919 for the new members. Patch by Ko van der Sloot.
921 Added support for SRU POST. It is supported for content-type
922 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
924 Do not build the separate Multi-threaded (MT) library libyazthread.la.
925 Instead make the library libyaz.la multi-threaded. Threading as a whole
926 can still be disabled by configure option --disable-threads. Previosly,
927 with older GLIBCs there were problems with MT libs under Apache. This
928 has now been fixed a long time ago.
930 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
933 CQL module modified to be case insensitive for relations/indexes/operations.
935 Fixed bug in CQL transform code: incorrect value relationModifieder
938 Added 'show all' command for yaz-client which retrieves all results
941 Added new yaz-client, xmles, which takes a (private) OID and
942 a document to be sent as an extended service request.
944 Describe new yaz-client commands wait_response and set_auto_wait.
946 Increase TCP/IP listener backlog from 3 (which I am guessing was
947 copied from the SunOS manual entry way back when) so SOMAXCONN, so
948 that the socket will queue as many incoming connections as it's able
949 to handle ongoing connections. In other words, it will never now
950 refuse a connection that it would be able to handle merely because
951 it's not got around to accepting() enough of the pending connections
952 yet. This is the behaviour anyway under Linux, where the listen()
953 argument is ignored; but not under BSD and on systems such as
954 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
955 YAZ-based servers should now be uniform across operating systems in
958 yaz-marcdump uses 64-bit file access on some systems. This is enabled
959 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
960 This allows yaz-marcdump to read large MARC batches (>2 GB).
962 Modified all YAZ source files - except the source which is auto-generated
963 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
966 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
967 corresponding to the existing *_setl() function. These allow option
968 values containing arbitrary valuues.
970 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
971 ZOOM_resultset_sort() in new applications. Its behaviour is identical
972 except that it returns an indicator of whether or not the sort
973 criterion was accepted (0 for OK, -1 for invalid).
977 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
978 MARC output rather than returning "new" buffer.
980 yaz-client warns about unknown init options.
982 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
986 Added support for SRW sort in Generic Frontend Server. Patch
987 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
988 sortKeys - or NULL if none is provided.
990 Fixed bug #307: It was impossible to specify indefinite/no timeout
991 for ZOOM_event. Special timeout value -1 now means indefinite timeout
994 Added support for multiple languages and charsets to be specified in
995 ZOOM. Each charset/language is separated by a blank. If negotiation is
996 in effect in init-response, Option
997 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
998 Code based on patch by Vasiliy Osadchuk.
1000 Fixed bug #306: infinite recursion that occurred when calling
1001 yaz_log_level_init as the first call (before other log level or
1004 Fixed bug in scan handling in front end server: if preferred-Position-In-
1005 Response was non-present, a NULL pointer referece was performed.
1007 --- 2.1.4 2005/04/26
1009 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1010 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1011 now defined for all those error codes. So instead of putting 109 in
1012 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1013 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1015 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1018 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1020 Program yaz-client now exits and produces an error message if multiple
1021 Z39.50 servers are specified on the command line (none or one allowed
1024 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1027 --- 2.1.2 2005/03/16
1029 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1031 Fixed bug #272: Preserve spacing for CCL terms.
1033 --- 2.1.0 2005/03/14
1035 Added support for virtual hosts and multiple backend servers for
1036 the YAZ frontend server. The configution is XML based and
1037 support specificition of CQL to RPN mappings and explain information.
1038 See section "Virtual Hosts" in the YAZ manual.
1040 Extended OPAC display utility. OPAC display utility renders
1041 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1042 to supplement yaz_marc_decode_wrbuf.
1044 Fixed a bug in MARC decoder that could caused it to crash for some
1045 invalid MARC records. More diagnostics and warnings where added in
1046 XML output (warnings, etc are stored in comments).
1048 --- 2.0.34 2005/02/08
1050 Fixes for UNIX domain sockets. Bug #261.
1052 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1054 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1055 Added yaz_marc_subfield_str which defines subfield lead string which is
1056 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1057 yaz_marc_endline_str which defines end of fields string used in
1058 YAZ_MARC_LINE format. Default string is newline.
1060 Experimental support for MarcXChange. This format can be produced
1061 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1062 http://www.bs.dk/standards/MarcXchange.xsd
1064 Added yaz-client commands scansize that sets maximum number of
1065 entries to be returned by scan.
1067 --- 2.0.32 2005/01/11
1069 Added support for SRW scan in yaz-client and Generic Frontend Server.
1071 * Added whereInList member to SRW Scan Term.
1073 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1075 Fixed NMEM system to return aligned blocks on the smallest boundaries
1076 that are suitably aligned for all possible types on the particular
1077 architecture YAZ is being built for.
1079 --- 2.0.30 2005/01/04
1081 Fixed numerious warnings that was issued with newer versions of GCC.
1083 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1084 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1087 Make YAZ Generic Frontend Server slightly faster.
1089 Enhance (and reduce) logging for Generic Frontend Server.
1091 Revert YAZ log system so that it flushes every write operation
1092 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1094 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1095 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1096 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1097 will effectively disable old definitions.
1099 --- 2.0.28 2004/11/09
1101 Added yaz_log_time_format which specifies log format using
1104 Added yaz_log_module_level which returns mask for a module. Value
1105 is non-zero mask a if module is enabled; zero if disabled.
1107 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1108 in include/yaz/cql.h.
1110 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1112 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1114 Fixed bug #172: RPM builds does not enable SSL.
1116 Doxyfile.in part of dist. Doxyfile generated by configure.
1118 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1119 are given and the corresponding component does not exist.
1121 Extend CCL documentation in YAZ reference. Describe r=r.
1123 --- 2.0.26 2004/10/01
1125 Fixed MARC->MARCXML conversion to properly deal with
1126 fields, subfields, indicators having non-ASCII characters.
1128 Fixed MARC->MARCXML conversion so that ASCII control characters
1129 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1132 Added YAZ GFS support for conversion from Z39.50 surrogate
1133 diagnostics to SRW surrogate diagnostics.
1135 Bug fix: YAZ GFS did not return schema in explainResponse.
1137 --- 2.0.25 2004/09/30
1139 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1140 now converts recordSchema to elementSetName as well as schema URI.
1142 Fixed bug in COMSTACK that prevented HTTP request packages from being
1145 --- 2.0.24 2004/09/29
1147 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1148 does not require white-space before and after the dash in a range, e.g.
1149 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1152 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1153 due to new GCC removing "redundant" code.
1155 Added yaz-client commands scanpos and scanstep that sets preferred
1156 position and step-size for scan.
1158 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1160 Added CCL utility ccl_qual_buf which parses one or more CCL
1161 spec lines in a buffer.
1163 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1164 of name and value - ignoring empty lines and comments.
1166 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1168 Added odr_get_element_path which returns current element path for an
1169 ODR handle. This utility is useful in error handling or user-defined
1172 Added ODR_PRINT utility odr_set_stream which is is a more generic
1173 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1174 to a write function and pointer to close function. The close function - if
1175 non-NULL - will be called during odr_destroy.
1177 Fixed bug in CCL parser where truncation char was not removed from
1178 right side when truncation=both was in effect.
1180 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1183 --- 2.0.23 2004/08/11
1185 Fix buffer overrun in CQL parser when dealing with proximity (%).
1187 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1188 to UTF-8/UCS conversion is now only based on codetables.xml.
1190 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1192 --- 2.0.22 2004/08/06
1194 Add support for more "commit changes" in ZOOM (uses Extended Services).
1196 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1199 Yet another small fix for configure of SSL.
1201 --- 2.0.21 2004/05/14
1203 Fix SSL libs for configure when --with-openssl=DIR is given.
1205 --- 2.0.20 2004/05/10
1207 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1209 SSL comstack now uses yaz.pem certificate file on server side
1210 by default. Certificate filename can be configured by calling
1211 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1213 Fix bug regarding multiple calls to ZOOM_connection_connect.
1215 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1217 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1218 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1220 ZOOM now allows inspection of X509 peer certificate for verification.
1221 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1223 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1224 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1225 as "modular" but it simplifies things.
1227 Added cs_get_peer_certificate to that returns peer X509 PEM.
1229 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1230 NULL if SSL is unavailable.
1232 Documentation about MARC decoding tools.
1234 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1236 --- 2.0.19 2004/03/30
1238 Rename CHANGELOG to NEWS to follow GNU style packing.
1240 Fix bug with missing initialization of member in init_diagnostics.
1241 This bug affects threaded version of GFS server.
1243 --- 2.0.18 2004/03/20
1245 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1248 Ensure zlib.dll is packed with Windows install.
1250 --- 2.0.17 2004/03/17
1252 Fix encoding of xsd:string to use text instead of CDATA.
1254 Fix endless loop in CQL parser with unbalanced ".
1256 Use a more compact way to store MARC-8 conversion tables.
1258 --- 2.0.16 2004/03/16 Debian only
1260 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1263 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1268 --- 2.0.15 2004/03/01
1270 Another fix for decoding of XML packed records.
1272 --- 2.0.14 2004/02/25
1274 Fixes for Chunked encoding. White space not ignored after length spec.
1276 Update NS and use default NS for SRW diagnostic elements.
1278 --- 2.0.13 2004/02/23
1280 Implement ZOOM_resultset_cache_reset which resets record cache.
1282 Implement ZOOM_resultset_sort which sorts a result set.
1284 Implement chunked HTTP transfer.
1286 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1288 --- 2.0.12 2004/02/16
1290 Added member 'schema' to bend_explain_rr structure so that backend
1291 can specify explain record identifier. Defaults to Zeerex 2.0.
1293 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1295 --- 2.0.11 2004/02/16
1297 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1300 Added init command for yaz-client which sends "extra" init request.
1302 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1303 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1305 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1307 Make ZOOM error code for "invalid query".
1309 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1311 --- 2.0.10 2004/02/05
1313 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1316 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1318 Added option -p <file> to make Generic Frontend Server to write PID file.
1320 Added option -D to put Generic Frontend Server in background on its own.
1322 Make ZOOM C recognize option "password". If unset, "pass" is used
1323 (for backwards compatibility).
1325 Fixed a bug in Generic Frontend Server that could make it crash if a
1326 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1329 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1330 Must be issued before open, in order to be in effect.
1332 --- 2.0.9-6 2004/01/12 Debian/Windows
1334 Make the SRU server more picky WRT unknown params, etc.
1336 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1338 New YAZ client command, options, that sets Z39.50 options.
1340 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1341 options from a string of tokens (one token for each option bit).
1343 Update SRW diagnostic code messages.
1345 --- 2.0.9-5 2004/01/07 Debian/Windows
1347 Handle user defined stylesheet for SRW/SRU.
1349 --- 2.0.9-4 2004/01/06 Debian/Windows
1351 Fix bug in decoding of Content-Length.
1353 --- 2.0.9-3 2004/01/06 Debian/Windows
1355 Fix a bug with decoding of XML packed records.
1357 --- 2.0.9-2 2004/01/05 Debian only
1359 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1361 Fix bug in SRW/SRU diagnostics decoding.
1363 --- 2.0.9 2004/01/05
1365 Fixed bug in Generic Frontend Server which could drop records exceeding
1366 preferred message size. Reported and fixed by Irina Dijour.
1368 Fixed calculation of package size for structured records in Generic
1369 Frontend Server. Reported and fixed by Irina Dijour.
1371 Fixed namespace for SRW/SRU diagnostics.
1373 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1375 --- 2.0.8 2003/12/22
1377 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1378 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1381 CQL changes to reflect recent changes to the specification:
1382 * Documentation talks about context sets instead of index sets.
1383 * Documentation talks about indexes instead of qualifiers.
1384 * The CQL-to-PQF transformer's configuration file now uses
1385 "index.set.name = <attributes>" instead of the old form
1386 "qualifier.set.name = <attributes>". (Both forms are still
1387 understood but the latter is deprecated.)
1388 * CQL terms with no explicit index specified are now interpreted as
1389 cql.serverChoice instead of srw.serverChoice (which of course
1390 behaves exactly the same.)
1392 --- 2.0.7 2003/12/16
1394 MARC conversion can now generate ISO2709 output in another
1395 character set. yaz-marcdump uses this facility if you invoke it
1398 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1399 functions from there can be used from C++.
1401 --- 2.0.6 2003/12/04
1403 Frontend server now transfers memory from decoded packages to stream
1406 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1407 references to show up.
1409 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1410 the ZOOM Abstract API. The older names for the same options are still
1411 also supported for the benefit of old applications.
1413 ZOOM-C supports "implementationId" and "implementationVersion" options
1414 to go along with "implementationName". These allow the user code to
1415 specify identification strings to be sent to servers.
1416 Add OID for the new ExtLite attribute set.
1418 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1419 as requested/supplid by Ere Maijala <ere@atp.fi>
1421 For generic frontend server, reverse the order of
1422 "toolkit-supplied / application-supplied" strings sent as implementationId,
1423 Name and Version. Also, remove the spaces around the slash. This brings
1424 the GFS in line with the behaviour of ZOOM-C on the client side.
1426 Add function ZOOM_scanset_display_term.
1428 yaz-client shows scan displayTerm if present.
1430 Utility yaz-iconv is now installed by default along with the man page
1433 Extend configure check for OpenSSL to use pkg-config where available (such
1436 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1437 server to specify uid/gid/mask for socket using the format
1438 unix:[user=uid,][group=gid,][umask=mask,]file=path
1439 If file= is omitted the existing format is assumed, e.g.
1441 in which case the mask is 0666 (rw for everybody).
1443 Major restructure of YAZ source. All source in libyaz is in src directory.
1444 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1445 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1447 Added man page for utility yaz-marcdump (used to be called marcdump).
1448 yaz-marcdump is installed by 'make install'.
1450 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1451 of incoming package failed.
1453 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1455 Change prototype of odr_perror: add const to message string.
1457 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1459 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1460 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1461 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1462 DNS lookup. There should not be any compatibility problems with this
1463 assuming that blocking=1 or 0 is used.
1465 Fix bad reference in UNIX comstack in function cs_addrstr.
1467 Fix for compilation on AIX.
1469 The generic front-end server (server/seshigh.c) now supports returning
1470 Init diagnostics to the client in User-information-field, in
1471 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1474 --- 2.0.4 2003/09/04
1476 Allow any CQL relation (not just all,any,exact,scr).
1478 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1479 that features the same UI.
1481 Implemented command update0 in YAZ client which is equivalent to
1482 update but uses old of Ext Update ASN.1.
1484 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1485 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1486 Previously no OID was used for this info.
1488 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1489 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1490 returns 'malformed search term' otherwise.
1492 SortResponse member resultCount now set to NULL in sort handler of
1495 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1498 Add three new utility functions for translating OIDs between various
1499 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1500 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1501 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1502 char *oid_to_dotstring(const int *oid, char *oidbuf);
1503 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1505 Reverted modifications for ES Update definition for z_IU0Update
1506 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1507 is back to YAZ 2.0.2.
1509 String value attributes for CCL parser.
1511 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1512 which their FirstSearch server returns in Init responses, sometimes
1513 carrying useful diagnostic information when Init fails. This has the
1514 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1515 "z39.50/oclcui.asn", where its definition is somewhat different from
1516 what OCLC document on their web-site, as required to interoperate with
1519 Support for anonymous authentication in yaz-client. Use the command
1522 * Fix the OID of the Index Data-local "admin" Extended Service from
1523 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1524 the 1000, which indicates a locally-defined OID, was a mistake.
1526 --- 2.0.3 2003/06/20
1528 Fix CCL directive @case handling so that it affects string match for
1529 both CCL keywords and qualifiers.
1531 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1532 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1533 Decoder has been updated with ASN.1 changes as listed in
1534 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1535 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1536 z_IUUpdate, remains unchanged.
1538 ZOOM_record_get may now return a record in a specific character set.
1539 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1540 "from" is the character set of record as returned by target. "to" is
1541 the character set to be returned. If omitted, "to" is UTF-8.
1543 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1545 New ODR utility, odr_getelement, which returns name of element for
1546 which encoding/decoding failed.
1548 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1549 in cases where a required element was omitted.
1551 Bug fix: some MARC8 sequences were not converted.
1553 New ZOOM option "step" which specifies number of records to be
1554 retrieved in one chunk. Used in conjunction with "start" and "count".
1556 SRW support for yaz-client. Use scheme http: to use it, e.g.
1559 yaz-client no longer does (un)intelligent character set conversions
1560 by default. Can be enabled with charset and marc_charset commands.
1562 xmalloc trace fix for 64-bit systems such as DEC alpha.
1564 Solaris 2.6 compile fix.
1566 New function, cql_strerror() translates SRW error codes, as returned
1567 by cql_transform_error(), into human-readable English strings. Used
1568 in yaz-client diagnostics when appropriate.
1570 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1571 converts it into a type-1 query which is sent to the server. This
1572 makes CQL available for use with all Z-servers, as opposed to the tiny
1573 minority that can handle CQL queries themselves.
1575 --- 2.0.2 2003/04/28
1577 New Debian package layout similar to the Redhat Package layout.
1579 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1580 and search result respectively.
1582 --- 2.0.1 2003/04/25
1584 Redhat package is now several packages: libyaz (runtime libraries),
1585 libyaz-devel (development and documentation, and yaz (utility programs).
1586 Package spec file by Morten Bogeskov.
1588 New member 'schema' in struct bend_fetch_rr which the name of requested
1589 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1590 handler MAY set this to reflect the schema of the returned record.
1592 New member 'display_term' in struct scan_entry. GFS now sets member entries
1593 and allocates scan entries to be filled by user scan handler. In previous
1594 version, entries member was allocated by the scan handler. That still works,
1595 but the GFS will ignore member display_term - assuming it was NOT set by
1596 the handler. The fact that the GFS now allocates the entries both allows
1597 for new members and makes a scan handler easier to write.
1599 Fix CQL lex buffer overflow.
1601 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1602 SRU default recordPacking is string.
1604 SRU protocol support for frontend server.
1606 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1608 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1610 Added scan for the ZOOM shell (zoomsh).
1614 * String Identifers for Schemas (Amendment 5).
1615 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1616 Old definition for schema
1617 Odr_oid *schema; /* OPT */
1622 Z_InternationalString *uri;
1623 #define Z_Schema_oid 1
1624 #define Z_Schema_uri 2
1627 * resultCount parameter to Sort Response (Amendment 1).
1628 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1630 Support for SRW 1.0 over HTTP. This is an optional feature and
1631 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1634 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1635 on the same port. SRW SearchRetrieveRequests are mapped
1636 to bend_init,bend_search,bend_fetch,bend_close.
1638 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1640 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1641 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1643 ZOOM connections are SRW based if schem http is used for hostname
1644 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1645 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1647 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1648 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1649 distance=n, order=true/false, relation=le, prox unit=word. If
1650 n is omitted, distance 1 is used.
1652 Fixed problem with C compiler include path in wrong order.
1654 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1655 on Solaris. Patch from Ko van der Sloot.
1657 New MARC decode API. All new functions operate on a yaz_marc_t
1658 handle. The most important new functions are: yaz_marc_create,
1659 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1660 decode and destroy respectively. Decoder can produce formats
1661 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1662 include/yaz/marcdisp.h.
1664 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1665 to UTF-8, UCS-32, wchar_t or Latin-1.
1667 * Prototypes for yaz_iconv_-functions moved to separate header
1668 include/yaz/yaz-iconv.h.
1670 Make a few private functions 'static' in unix.c. This prevents
1671 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1673 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1674 are set when Init Response is received.
1676 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1677 but returns diagnostic set as well.
1679 New function yaz_strerror which is a portable wrapper for
1680 strerror/strerror_r/GetLastMessage.
1682 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1683 is returned for MARC. If type is "oai", then OAI MARC is returned.
1685 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1688 --- 1.9.2 2002/11/26
1690 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1692 Fix bad race conditions on SIGTERM and terminate gracefully in
1695 Move retrieval (data1) module to Zebra since nobody seems to be
1698 Add GRS-1 render for ZOOM using same format as yaz-client.
1700 --- 1.9.1 2002/10/05
1702 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1704 Fix broken ESpec handling in data1 module.
1706 SGML reader parses comments and makes them part of the data1 tree.
1708 Added several type casts so that YAZ compiles as C++ code.
1710 ZOOM didn't handle PDU encoding failures properly.
1712 Added more Bib-1 diagnostics (approved extensions).
1714 GNU configure: better check for iconv.
1716 More portable use of accept, getpeername. Check for socklen_t. Use
1717 int/size_t if socklen_t is not defined.
1721 PQF parser rejects bad queries - including those with extra
1722 characters in them. PQF parser used to silently ignore that.
1723 Cleaner API for PQF added, which allows you to get detailed
1724 error information for bad queries (see yaz/pquery.h).
1726 Fixed bug in ZOOM_record_get for type "database".
1728 Implemented mini iconv library supporting conversions between
1729 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1731 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1733 --- 1.8.9 2002/08/20
1735 Fixed ZOOM C record cache so that preferredRecordSyntax and
1736 elementSetName is used to check for already fetched records.
1738 --- 1.8.8 2002/08/02
1740 Added three members in bend_initrequest structure to facilitate
1741 character set negotiation.
1743 Fixed a bug in frontend server that could cause indefinite
1744 loops under rare conditions.
1746 Revised character set utilities (charneg.h) so that encoding
1747 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1749 For PQF, directive @term <type> sets term type for Scan/Search.
1750 Here <type> is general, string, numeric, null. The term type
1751 is inherited - just like @attr.
1753 New call odr_set_charset that sets character set conversion for
1754 international-strings on a ODR stream. Prototype is:
1755 int odr_set_charset(ODR o, const char *to, const char *from);
1756 The InternationalString is still represented as C string in YAZ
1757 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1758 won't). On the protocol level, you can use any encoding.
1760 Support for UNIX sockets in ZOOM.
1762 Solaris recv sometimes returns errno == ENOENT. It is treated as
1763 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1765 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1766 both client and server. Code by Morten Bogeskov.
1768 --- 1.8.7 2002/05/22
1770 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1771 that they can be used directly from Visual Basic. You must recompile
1772 your windows APP if you're using ZOOM.
1774 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1775 Commands "lang" and "charset" sets language and character set respectively.
1776 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1777 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1779 Attributes from multiple CCL fields may be OR'ed rather than merged
1780 using directive "@field or". Fields are still merged by default -
1781 equivalent to "@field merge".
1783 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1786 Fixed bug in zget for parameter ExtendedServicesResponse.
1790 --- 1.8.6 2002/03/25
1792 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1794 Client displays USR.1:SearchResult-1 (hits per term).
1796 Additional Search Info for search in Generic Frontend Server.
1798 Fixed CCL parsing of "field=s".
1800 WIN32 installer - using the excellent NSIS software from nullsoft.
1802 Fixed CCL parsing of "field = - <number>".
1804 Added function yaz_marc_decode that decodes MARC for line mode
1805 display or XML (similar to that used by JZKit).
1807 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1808 Z39.50. But ISO/ILL was, however.
1810 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1811 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1813 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1814 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1816 --- 1.8.5 2002/02/03
1818 New YAZ client features: Command completion and new commands:
1819 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1820 Code provided by Jacob Poulsen.
1822 New call oid_trav, that visits all registered OIDs via callback.
1824 Function ZOOM_record_get now returns const char pointer rather than
1825 void pointer. It saves a lot of type casts.
1827 For YAZ client, command "auth" now allows you to set authentication
1828 in IdPass style. It is enabled when three tokens are given - order
1829 is user, group and password.
1831 Fix memory leaks in MARC record handling for ZOOM.
1833 New option for YAZ client, -k <kilobytes> that sets
1834 maximum record size. Similar to -k option for generic frontend
1835 server and yaz-ztest.
1837 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1839 Prefix query parser reports "fail" when bad attribute set is given.
1841 Fix in MARC decoder. Proximity logging. Fix for attribute set
1842 in scan handler for server. Patches by Shigeru Ishida.
1844 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1847 Configure option --with-openssl=<dir> now works when a directory is
1848 specified. Patch provided by Morten Bogeskov.
1850 New option for YAZ client, -u <auth>, that sets authentication.
1852 ZOOM fix: error information was sometimes "missing", since error
1853 was cleared/reset too when it shouldn't.
1855 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1857 --- 1.8.4 2002/01/04
1859 Scan for ZOOM API. New object ZOOM_scanset. New functions
1860 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1861 ZOOM_scanset_destroy.
1863 New ZOOM function, ZOOM_connection_last_event, that returns type
1864 of last event (such as "receive data", "send data", "apdu received",
1867 New ZOOM option, schema, that specifies schema for retrieval.
1869 New CCL feature. Qualifiers can be aliases for one or more
1870 other qualifiers (if more than one is given, OR is used).
1872 ZOOM uses named result sets if target supports it.
1874 Two new YAZ client commands: . (dot, which sources a script of YAZ
1875 client commands), and ! (to execute shell command.). Implemented
1878 Working on Debian packages.
1880 --- 1.8.3 2001/11/19
1882 YAZ client enables named result sets only if target supports it.
1884 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1886 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1887 with key="host" to get same result.
1889 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1890 Function Z3950_resultset_record(s) returns references to records
1891 "owned" by resultset. To become owner use Z3950_record_clone.
1893 Function z_ext_record handles Extended Services. Thanks to
1896 --- 1.8.2 2001/11/12
1898 CCL Parser fix: ignore token comma when dealing with and-lists.
1900 Documentation updates for COMSTACK.
1902 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1903 Changed prototype Z3950_records. For some functions, int parameters
1904 were changed to size_t.
1906 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1909 New MARC decode/display function, marc_display_exl, which properly rejects
1910 non-ISO2709 records. YAZ client uses it.
1912 --- 1.8.1 2001/10/29
1914 Fix bug: local attribute set wasn't set correctly in PQF strings.
1918 * Old Z39.50 codecs no longer supported.
1920 Added ZOOM C binding. See http://zoom.z3950.org/
1922 Renamed states for COMSTACKs to avoid confusion with events.
1924 Implemented cs_look and proper cs_rcvconnect.
1926 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1928 Configure detects POSIX threads on OpenBSD.
1930 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1931 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1933 When error is returned from present handler, non-surrogate diagnostic
1934 is returned in present response (and fetch handler is no longer called).
1936 * Minor adjustments to pquery parser (PQF). Token characters may be
1937 escaped by using backslash (C-style).
1939 PQF parser allows string attribute values to be specified. For @attr,
1940 non-numeric characters after the equal-sign are treated as strings
1941 (e.g. @attr 9=title).
1943 CCL trunction character may be defined (@truncation in file)
1945 * function zget_ExtendedServicesRequest sets waitAction to
1946 waitIfPossible (was wait).
1948 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1951 CCL operator names may be set in field definition files (CCL_bibset).
1952 See ccl/bib1 for an example.
1954 Fixes in ASN.1 compiler for C++ compatibility.
1956 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1957 and "op_or" to avoid conflict with C++.
1959 Fixed problem with GNU readline detection on Redhat 7.0.
1961 Added step-size for Scan backend handler.
1963 Fixed bug that made the frontend server crash when no attribute
1964 set was specified for scan.
1966 Front-end server automatically switches to original working directory
1967 when installed as an NT service. Previously -w had to be specified to
1970 Added extended attributes for retrieval module (data1), so that data1
1971 records carry d1_readXML/SGML attributes. d1_read also supports
1972 null-data rules ( <tag/>)
1974 On UNIX when POSIX threads are available, a separate library libyazthread
1975 is created. Programmers should link with that library and the yaz library
1976 when using threads. The reason for the split was that some applications
1977 on Linux, such as Apache, doesn't work well when using shared objects that
1980 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1981 (or any frontend server) in SSL mode by specifying ssl: followed by
1982 address. Only tested on UNIX.
1984 Added feature for CCL module. Virtual structure s=al or s=ol generates
1985 and-list and or-list respectively instead of phrase search.
1989 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1990 log_mask_str. This was done to avoid name conflicts with other libraries
1991 (such as other PHP extensions).
1993 Added raw OID member for preferred record syntax (request_format_raw)
1994 and returned record syntax (output_format_raw) for backend fetch method.
1996 Config file yaz-config now accepts options so that it returns specific
1997 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1999 Shared library support for UNIX using GNU libtool.
2001 * Modified backend interface. Request/Response struct's replaced by
2002 one read/write C struct. For example bend_fetchrequest and
2003 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2004 Every handler - even search has to be registered in bend_init
2005 handler. This means that the YAZ library no longer refers to
2006 external functions and it makes it possible to make the whole
2007 thing a single DLL/SO.
2009 Added Segment handler for backend server.
2011 Added Zmbol/Zebra administrative functions to YAZ client.
2013 Threaded frontend server on UNIX (when POSIX Threads are available).
2014 Starting the server with option -T enables multi-threading.
2018 Added configure option --enable-comp/disable-comp to control use
2019 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2020 located in sub directory asn.
2022 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2023 in ${exec_prefix}/bin along with the other programs yaz-client and
2026 GNU automake used to maintain makefiles.
2028 Added several OID's.
2030 Changed retrieval module so that we can load records with no abstract
2031 syntax defined. Tagpaths in these records are fully composed of string
2034 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2038 On UNIX, the generated makefile now supports a proper 'make install'.
2039 The prefix can be set via GNU configure to set the install location
2040 (default is /usr/local).
2042 * YAZ programs client and ztest were renamed to yaz-client and
2043 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2044 locations, such as /usr/bin,/usr/local/bin,etc.
2046 * YAZ Header files were moved from include to include/yaz. YAZ Header
2047 files are referred to as include <yaz/log.h> rather than <log.h>.
2048 The YAZ include path (-I ..) is therefore the same as before. Programmers
2049 should update their #include statements or use -Ipath/include/yaz
2050 instead. The main motivation for doing this change is that YAZ header files
2051 can be installed in "standard" locations /usr/include,/usr/local/include
2052 without introducing conflicts, since ALL YAZ header files are stored
2053 in subdirectory yaz (under /usr/include for example).
2055 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2056 rather than project/workspace files. We switched because project files
2057 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2060 Changed name of logging function, logf, to yaz_log, to prevent name
2061 clash with some math-log functions. The YAZ header log.h defines logf
2062 to yaz_log (#define) so there should be no incompatibilities by this
2065 Added bend_start/bend_stop handlers for server. These handler are
2066 called on start/stop of server. For windows they are called whenever
2067 a service is started/stopped.
2069 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2070 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2071 in util/yc.tcl. The auto-generated C code structures are, in a few
2072 cases, incompatible with the old decoders. There are differences in the
2073 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2074 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2075 The preprocessor variable ASN_COMPILED is defined when the compiled
2076 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2077 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2078 wish to use the old encoders/decoders you can specify --disable-yc
2081 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2082 version so that it supports both new - and old version of DB Update
2084 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2085 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2086 change. The name parameter can be set to 0 in which no name is specified
2087 for the construction. The macros odr_implicit and odr_explicit sets name
2088 parameter to zero for the construction involved. New macros
2089 odr_implicit_tag and odr_explicit_tag are similar to the others,
2090 except that a name parameter is added. For programmers' that don't use
2091 ODR they probably only need to change the call to z_APDU and z_External.
2093 Added access control facility by interfacing the TCP wrapper library.
2094 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2095 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2096 name of the daemon and enables the access control as specified in
2097 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2099 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2100 den Dool <H.M.vdnDool@kub.nl>.
2102 Added reference ID parameter to most functions in server API - refer
2103 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2105 Changed name of ccl library to libccl.a (was ccl.a).
2107 Fixed bug in decoder for Explain (Category TargetInfo).
2109 Added support for GNU readline in client. Thanks to Jacob Poulsen
2110 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2112 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2113 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2114 IMPLEMENTATION! This change was made to the development version before
2115 the ZIG decided to retract the amendment. If any users MUST be
2116 compatible with the original Update definition, PLEASE CONTACT US, and
2117 we will include a separate definition corresponding to the old Update
2118 ES. Note that because of the change to the ASN.1 of the
2119 TaskPackageRecordStructure we cannot define a single structure that
2120 will support both versions.
2122 * Added const modifier to buffer parameter for some ODR/BER encoding
2123 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2124 completeWAIS, odr_dumpBER.
2126 Fixed bug in client.c which caused a crash when a scanResponse didn't
2127 contain positionOfTerm.
2129 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2130 * will cause an error in a client if a non-YAZ target sends both a
2131 * list of Scan entries and non-surrogate diagnostics.
2133 Retrieval module enhancements. Tag sets may be typed in the reference
2134 to it. From the .abs-file the "tagset" directive takes a third optional
2135 integer type for the tag set referenced. From a .tag-file the "include"
2136 directive takes a third optional type as well. The old "type" directive
2137 in the tag set itself is still recognized but acts as the default type
2140 Backend interface change. Individual Scan terms returned from bend_scan
2141 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2142 in include/backend.h.
2144 Retrieval module enhancements. Multiple tag sets and attribute sets may
2145 be specified in abstract syntax specs. Revised the error/warning for
2146 logging messages reported by the retrieval module when reading the
2149 Object Identifier system (oid_..) changed. The API is backwards
2150 compatible but the oid-routines now allocates new OID's when needed.
2151 Raw OID's may be specified in oid_getvalbyname.
2153 YAZ now uses GNU configure to generate Makefile(s).
2155 * Minor changes in some of the member names of DeleteResultSetRequest and
2156 DeleteResultSetResponse. See include/proto.h.
2158 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2159 and added member 'languages' in TargetInfo (which was missing).
2161 Changed the way attribute sets are handled in the retrieval
2162 module. These are now cached, just like the abstract syntaxes
2165 Changed YAZ so that it links with compiled ASN.1.
2167 Added Explain-schema definitions and mapping routines. The following
2168 Explain categories have been implemented: AttributeDetails,
2169 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2171 Fixed minor bug in Windows version of Server Library.
2173 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2175 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2177 Added EXTERNAL: UNIverse Resource Report (non-standard).
2179 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2180 ENUMERATED and SET OF.
2182 * Added 'const' to some of the char pointer arguments for the
2183 functions, data1_read_node, data1_getelementbytagname,
2184 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2187 Fixed bug in data1_insert_taggeddata - the last_child member of
2188 parent wasn't initialised.
2190 * Changed data1_read_record and data1_read_node so that the supplied
2191 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2192 doesn't refer to any parts of the "SGML"-buffer.
2194 Fixed bug in server library (Windows version of statserv_remove).
2196 * Changed code so that it compiles as C++. The type definition
2197 of Odr_fun which is a member of Odr_arm was changed. The result is,
2198 that an explicit typecast is needed for the fun pointer when
2199 using Odr_arm - as in:
2200 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2202 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2204 Implemented the new structured date and time definition as approved
2205 by the ZIG. Added schemaId element to the specificTag in Espec-1
2206 (also approved at the last ZIG). Thanks to RVDM.
2208 Added some Object identifiers (RVDM).
2210 Changed the Update Extended Service (RVDM).
2212 Added command "refid" to client which specifies referenceId for
2213 the following requests.
2215 Implemented extended service handling for server. See ztest.c
2216 for an example as well as backend.h. New handlers are registerd
2217 in the Init handler.
2219 * Changed interface for sort in server.
2221 Added new members to statserv_options_block. It allows a server
2222 to read options from another source than just the command line. Thanks
2223 to Charles Woodfield.
2225 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2226 renamed to zboolean. Some C++ compilers complained about the name.
2228 Minor changes to gils.abs. Added index 's' (sort) on title
2229 and date/time-last-modified.
2231 --- 1.4pl2 1998/1/30
2233 Fixed bug in server library regarding inetd mode (-i). This bug
2234 was introduced by release 1.4.
2236 --- 1.4pl1 1998/1/29
2238 Added sort facility in client and backend server interface.
2240 Fixed problem with dependencies in Makefile(s).
2242 Fixed bugs for encoders/decoders of extended services and
2245 Implemented sub-tree feature for schemas. Sub-trees are
2246 referenced in *.abs-files. See explain.abs for an example
2247 of the use of this feature.
2249 Modified bib1.att; local attributes for ANY didn't include
2250 ANY itself (only affects use of the retrieval module).
2252 Fixed bug in plain SGML reader in function data1_read_node:
2253 tags with prefix "var" was incorrectly interpreted as variants.
2255 Added feature "sub-schemas" to enable references to - and definitions
2256 of - group of elements.
2258 * Removed member parent from type data1_element (in data1.h).
2260 Implemented function odr_nullval() that returns the value of
2263 * Removed member num_children from data1_node (in data1.h).
2265 Made NT service interface part of the server library. The
2266 function statserv_main uses the NT service when required and
2267 calls the statserv_start / statserv_close routines.
2269 Routine zget_SearchRequest and zget_PresentRequest fills
2270 resultSetName/Id member with "default" instead of "Default".
2272 Fixed memory leak in server. Request queue member wasn't freed.
2274 Fixed nmem_exit so that memory is freed.
2278 Revised the CCL parser utility to be thread safe.
2280 Added function, oid_ent_to_oid, to replace the function
2281 oid_getoidbyent, which is not thread safe.
2283 * Added nmem_init and nmem_exit to initialize and release
2284 NMEM resources. Function nmem_init should be called once in the
2285 initial thread before NMEM/ODR is used. statserv.c and client.c
2286 have been changed accordingly. The change was necessary to make
2287 NMEM thread safe. The NMEM memory pool is shared amongst threads
2288 in a process. Unix-based applications will still work fine without
2291 Added NT Services interface for the the Z39.50 (statserv) Server.
2292 Refer to the ztest.c source on the usage.
2294 Windows 95/NT port using MSVC5.0. Project files are included in the
2297 * Defined new 'global' handle for the retrieval (data1) system. The
2298 new handled, data1_handle, describes the state of the data1 system.
2299 This handle is passed as first argument to virtually all
2300 data1 related routines. The functions data1_create and data1_destroy
2301 creates and destroys a data1 handle respectively.
2303 Added ODR encode stream member to all backend request structures
2304 init, search, scan etc. This stream should be used to allocate all
2305 memory used for the response when thread safe operation is needed.
2307 Changed the comstack utility, cs_addstr, to be thread safe. The
2308 returned hostname string returned by the function is now part the
2311 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2312 function. The cs_straddr takes a COMSTACK handle as argument, so this
2313 function must be used after cs_create and before bind/connect.
2314 This function is thread safe.
2316 Moved test server to 'ztest' directory - generic server code still
2317 in 'server' directory.
2319 Made prefix query (pquery.c) utility thread safe.
2321 Added new function modifier YAZ_EXPORT to 'export' public DLL
2322 functions when using windows (see include/yconfig.h).
2324 Added definitions to the OID database (util/oid.c) (RVDM).
2326 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2328 Added call to ccl_rpn_delete in client program.
2330 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2331 release of RPN structure.
2333 Added support for C++, headers uses extern "C" for public definitions.
2334 With input from RVDM.
2336 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2337 Thanks to Ronald van der Meer (RVDM).
2339 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2341 Added support for private extensions to the OID database
2342 (oid_setprivateoids()). Thanks to RVDM.
2344 Added optional, physical ANY (key replication)
2346 Fixed null-reference problem in GRS-1 output filter.
2348 Proximity operator added to Prefix Query Format (PQF).
2350 In test client command "base" accepts multiple databases.
2352 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2356 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2358 Smallish bug-fixes in the new encoders/decoders (explain).
2360 Bug fixed in DeleteRequest.
2362 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2364 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2366 Added SOIF syntax (using private OID for now) to retrieval module and client.
2368 Added Update extended service.
2370 Added SearchResult-1 additional info structure.
2372 Added optional CCL (ISO8777) interpreter as separate module. Available
2375 --- 1.2 1996/6/10 (1st anniversary release)
2377 Added Summary record syntax. Lightly tested.
2379 Added OPAC record syntax. Untested.
2381 Added ResourceReport service encoders/decoders. Untested.
2383 Fixed bug in z_Unit - wrong tagging on unitSystem.
2385 Fixed bug in the DiagRecs decoder.
2387 Added options for max PDU size and session timeout to frontend-server.
2389 Added documentation of query-language parsers and other supporting utilities.
2391 [frontend-server] Added Attribute set to the bend_scanrequest API.
2393 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2394 surrogate diagnostics were generated.
2396 [retrieval] Allow multiple local values for attribute.
2398 [retrieval] Allow multiple attributes per element in .abs files. index type.
2400 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2402 --- 1.1pl2 1996/4/10
2404 Minor changes, mostly specific to Zebra's requirements (retrieval)
2408 Repaired bug in frontend server when running multiple listening
2409 endpoints in dynamic mode.
2411 z_External() now won't break if a known, ASN.1 value comes encapsulated
2412 in an octet-string. The value will pass through unmodified in an Odr_oct.
2414 Added a bit of code to the demo client to decode & display
2415 ASN.1-structured records represented in the octet-aligned branch of
2416 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2418 Added z_ext_getentbyref() to the ASN module. Doc updated.
2420 * Completed the SCAN definition in the ASN module. This may break SCAN
2421 code based on older YAZ-versions at compile-time. The fix is easy -
2424 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2425 under the SCAN definition. Remember to initialize this, server-people.
2427 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2428 that this does not extend to ODR and ASN.
2430 Comstack allows insertion of established socket (primarily for
2431 inetd-operation of servers). Doc updated.
2433 Front-end server can now start from the inetd in TCP mode. Doc
2436 --- 1.0pl4 1996/1/24
2440 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2441 the rank and record number.
2443 Adjustments to the frontend server.
2445 Fixed diagnostic BER dumper. It ignored the file argument.
2449 Various changes to retrieval module.
2451 Changed the union discriminators of the protocol files from enums to
2452 ints paired with #defines.
2454 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2457 *Changed operator in the RPN structure to 'roperator', again to avoid a
2460 Fixed problems in Explain decoders/encoders.
2462 --- 1.0pl2 1995/12/6
2464 Memory bug in log module fixed.
2466 --- 1.0pl1 1995/12/5
2468 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2470 Bug in Explain DatabaseInfo module fixed.
2472 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2476 The shift to v1.0 signals that we now consider the *core* functionality
2477 of YAZ reasonably stable (the core being more or less equivalent to
2478 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2479 tested (Explain not at all - though that will happen soonish).
2481 Minor changes to code to support Windows port.
2483 Various minor changes after we're getting to use GRS-1 & co. more.
2485 Added Espec-1 format.
2487 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2488 of the protocol and it cannot be selected when encoding (maps into 'string'
2489 when decoding). Needed to talk to some servers.
2491 Demo client can request simple element set names.
2493 Added Diagnostic Format encoders/decoders.
2495 Added simple Close handling to frontend server (no hooks for resource
2496 reporting yet), and demonstration client.
2498 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2500 --- 1.0b3 1995/08/24
2502 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2503 handled incorrectly when records were requested in the searchResponse. This
2504 will only affect you if you use the frontend-server.
2506 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2507 Test-client will ask for and print GRS1. Ztest will return dummy records
2510 Added Explain encoders/decoders to the service-level API. Untested.
2512 Added Extended Services: Item Order encoders and decoders to the Service-
2513 level API. Untested. We could use a recent copy of the pertinent bits
2514 of the ILL protocol to add those bits.
2516 Added diagnostic format 1 encoders/decoders to the service-level API.
2519 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2520 odr_cons.c, which causes a more correct output.
2522 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2523 was always set to 0 when no records were requested in the searchRequest.
2525 * Added better external-handling. This shouldn't harm old code that
2526 *encodes* externals. It can break code that looks for a
2527 'single-ASN1-type' representation, since those types that are known
2528 are now decoded immediately. Look at the SUTRS sample code in
2529 seshigh.c and client.c. Documentation updated.
2531 Handling of structured records in bend_fetchresponse. Length -1 marks
2532 structured record, type is deduced from format field.
2534 --- 1.0b2 1995/06/27
2535 Fairly quick maintenance release to add SUTRS support.
2537 Fixed handling of SUTRS records in the demonstration client.
2539 * Added format field to the bend_fetchrequest and bend_fetchresponce
2540 structures of the backend API (frontend server). When the record is
2541 returned, the value of the format field is mapped to an OID. The
2542 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2543 of the record. The special value VAL_NONE in the bend_request means
2544 that no specific format was requested by the client. Documentation
2545 updated accordingly. Test server (ztest) will return a fixed dummy
2546 SUTRS record if your client requests SUTRS.
2548 Documentation updated accordingly.
2550 You can now set external libraries and RANLIB support in the top-level
2554 First public release.
