3 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
4 only the bibliographic record was rendered. For type=opac, an OPAC
5 record is only returned if it is present.
7 iconv: small fix for encoding of advancegreek.
9 yaz-client: avoid double display of SRU/SRW records (bug #2798).
11 yaz-client: option auto_reconnect=on really reconnects.
13 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
15 server: avoid null ptr ref for for yaz_poll errors.
17 build: fix RPM build for RHEL 5.3.
19 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
23 Fixed bug #2709: TCP connect returns Invalid argument.
25 Fixed compilation for mingw.
27 Honor charset for raw records (ZOOM_record_get).
29 Fixed use of errno for threaded mode that was seen on Solaris 10.
31 Fixed argument passing with blanks in value for Windows Service.
33 Disable YAZ' own log rotate by default (no 1 GB limit).
34 The variable l_max_size which specifies the log file limit is set to 0
35 (DISABLED): This is due to the fact that YAZ is most often deployed using
36 logrotate. Also YAZ can not perform log rotate because of unsufficient
41 List supported encodings in man page for yaz-iconv.
43 Fixed missing SSL libs for --libs output
45 Re-established OID record syntax application-xml. Nobody should use it
46 but we don't want to change soname because of this symbol being absent.
50 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
52 Added member named_result_sets for init handler struct for the GFS. This
53 allows a server to disable named result sets.
55 Removed OID record syntax application-xml.
57 Added support for rule-based transliterator for ICU wrapper of YAZ.
59 Fixed bug #1902: yaz-icu XML output.
61 Make YAZ checks Emacs friendly.
63 BITSTRING value shows value. Bug #2346.
65 ISO2709 decoding: skip control characters from indicator data.
67 Omit sort key by default in yaz-icu's output.
69 Allow combined single char options (again) for YAZ' options function.
71 Utility yaz-marcdump got option to display YAZ version (-V).
73 Allow YAZ to use ICU 3.4.
75 Added new ICU test case which illustrates removal of diacritics.
79 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
83 For configure, using option --without-xml2 also disables Libxslt/Libexslt
86 Fixed bug #2352: yaz-marcdump crashes for certain record.
88 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
90 Added support for Danmarc2 to UTF-8 conversion.
92 Added support for ISO5426 to UTF-8 conversion.
94 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
95 implementation version.
97 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
101 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
102 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
104 ZOOM C now interprets databaseName option for ZOOM connection as path
107 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
109 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
111 Dummy Libxml2 types no longer defined in headers of YAZ'.
113 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
116 --- 3.0.36 2008/09/26
118 Various ODR chapter fixes.
120 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
122 Added missing source for Windows compilation, mutex.c.
124 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
126 For SRU connections in ZOOM all records up to "count" are now fetched.
128 Fixed crash in generic frontend server (and yaz-ztest) which occurred
129 in Windows due to bad error handling for Libxml2.
131 Added facility for sending arbitrary records (ASN.1 any) using
132 ZOOM C's Extended service update. Patch by Sam Reynolds.
134 New options for ZOOM C's connection, logapdu which makes ZOOM log
137 --- 3.0.34 2008/06/18
139 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
141 --- 3.0.32 2008/06/12
143 Fixed memory violation that could occur when decoding UTF-8. This bug
144 was only present in 3.0.30 of YAZ.
146 --- 3.0.30 2008/06/06
148 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
149 GNU TLS is used by default (if found).
151 yaz-ztest returns OPAC records if a client asks for OPAC.
153 Improved speed of MARC-8 encoding.
155 Added support for lossy and loss-less MARC-8 encoding.
157 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
159 Added new Windows Service wrapper (sc).
161 yaz-client's itemorder command may now send a file.
163 Fixed yaz-marcdump to allow the use of NS prefix for record element.
165 Added new function yaz_log_xml_errors.
167 Allow (but warn) unknown XML attributes in MARCXML parsing.
169 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
171 The UTF-8 to MARC-8 conversion now uses a different set of characters
172 for Greek symbols. Bug #2120.
174 --- 3.0.26 2008/02/21
176 Added yaz_daemon (daemon.h).
178 Fixed bug #2068: pkg-config trouble
180 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
182 --- 3.0.24 2008/01/28
184 Document --with-xml2 option.
186 Added OPAC XML XSD (etc/opacxml.xsd).
188 Allow glob mask for name attribute in retrieval element for the
189 generic frontend server's retrieval facility.
191 Changed yaz_poll_poll to return yaz_poll_except for all returned events
192 except POLLIN/POLLOUT.
194 Fixed error handling in cs_listen. Bug #2037.
196 --- 3.0.22 2008/01/20
198 Fixed version in yaz/yaz-version.h.
200 Fixed bug #2027: Crash when closing connection.
202 Changed configure so that ICU support is only enabled if only ICU
203 and Libxml2 is available (because the ICU chain is XML based).
205 --- 3.0.20 2008/01/15
207 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
208 is built. Only this DLL depends on the ICU runtime.
210 yaz-ziffy is no longer part of YAZ. It is distributed separately by
211 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
213 Changed license of CCL module to 'Revised BSD'. After consultation with
214 remaining members of the original EUROPAGATE consortium, we are re-issuing
215 the CCL module without a separate license. The software was developed by
216 Index Data as part of a research project. The special license was included
217 to help feed usage information back to the project consortium to support
218 project evaluation. At this time, the project consortium has long-since
219 disbanded, and the majority of the original principals have retired. At the
220 same time, we have significantly modified the software during the following
221 years, to the point where very practically no original code remains. To
222 simplify re-use of the software, we have contacted those members of the
223 consortium who could be reached, and agreed to re-issue the module as a
224 proper part of the YAZ package.
226 Tcl scripts uses /usr/bin/tclsh as preferred shell.
228 CQL closer to being version 1.2 compliant. CQL also allows free-form
229 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
232 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
233 bug could make Extended services handling crash in the ZOOM layer. This
234 bug was only present in YAZ 3.0.18.
236 --- 3.0.18 2007/12/19
238 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
241 yaz-marcdump reads and writes collection wrapped records.
243 Handle OPAC for record conversion module.
245 Fixes for ICU wrapper.
247 Allow ICU libs to be controlled with --with-icu .
249 --- 3.0.16 2007/11/12
251 Added yaz_poll which is a wrapper for select/poll. When poll is available
252 and non-buggy, it is used, by yaz_poll . This allows more than 1024
253 sockets to be in use.
255 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
256 functionality through an XML based configuration (ICU chain). This system
257 is useful for search facilities such as Pazpar2 and Zebra that needs to
258 perform tokenization of indexed material. The ICU code in a separate
259 library libyaz3_icu.a.
261 Added HTTP tunnel facility for COMSTACK, bug #1752.
262 This is a facility that allows a Web proxy, such as squid, to tunnel
263 Z39.50 traffic. This facility is "transparent" to must applications
264 using YAZ. It's enabled by using pseudo transport connect: followed by
265 the proxy address, followed by command, then follwed by he regular
266 "virtual" addresss. For example,
267 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
269 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
271 --- 3.0.14 2007/09/21
273 Fixed bad memory reference in ZOOM_record - cuased by member not being
274 initialized. This was a problem only in YAZ 3.0.12.
276 Fixed bug in conversion from MARC to XML: Non-XML characters in control
277 fields were not removed.
279 Changed the way C code is generated from codetables.xml. Made a MARC-8
280 conversion trie for each characterSet section rather than codeTable.
281 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
282 of codetables.xml from Larry Dixson, LOC. Bug #1464.
284 --- 3.0.12 2007/09/12
286 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
287 from ZOOM_record_error).
289 ZOOM C function ZOOM_record_get returns record schema for type="schema".
291 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
293 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
295 Better SRW-to-Bib-1 diagnostic mapping.
297 ZOOM C and yaz-client announces SRU version 1.2 by default.
299 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
302 Fixed in yaz_sru_decode to allow other version than 1.1.
304 --- 3.0.10 2007/08/22
306 Added support for SRU scan for ZOOM.
308 Added support for the use of the older versions or Extended Service
309 Update in ZOOM. To faciliate this, an option "updateVersion" may be
310 set to the version , 1=first, 2=second, 3=third. The third version is
311 what ZOOM C has used so far. And that, obviously, is the default.
313 Added support for CCL queries in Z39.50 queries sent to the GFS (and
314 therefore in Zebra and in SimpleServer-based applications). The new
315 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
316 qualifier file used to transform incoming CCL queries into Type-1 RPN,
317 which is passed into the back-end search callback function.
319 Added support for HTTP Basic authentication in clients: the SRU/W
320 codec encodes the username/password elements of the PDU structure
321 appropriately, and these may be set using the "user" and "password"
322 options in ZOOM-C applications (the same options that are used for
323 Z39.50 authentication).
327 Fixed bug #1208: SSL appears to be broken in ZOOM.
329 Fixed bug #1206: Libxml2 include path weirdness.
331 Added oid_name_to_dotstring.
333 Allow elementSetName to be specified for ZOOM C record update.
335 Allow waitAction to be specified for ZOOM C based for Extended Services.
337 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
338 syntax OID. Bug introduced in YAZ 3 series.
340 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
344 Fixed bug #1157: yaz-client does not read .yazclientrc from current
345 directory. yaz-client now reads commands from file given by option -f
346 if specified; then tries to read .yazclientrc in current directory.
347 Failing that, it reads .yazclientrc from user's home directory.
349 Added support for correlationInfo Note and ID for Record Update via
352 Added yaz-client command querycharset which specifies character set for
353 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
354 (termListAndStartPoint).
356 Charset ISO5428:1984 is an alias for ISO5428-1984.
358 Implemented a way to perform scan in a result set using Z39.50. This
359 is achieved by attaching the result set name in the characterInfo
360 (type InternationalString) of OtherInformation in the Scan Request PDU.
361 The result set is identified in the otherinformation by the new OID:
362 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
363 This allows for scan in result set and faceted search . Zebra did some
364 of this in the APT term using attribute type 8 and value being result
365 set. Using the OtherInformation approach for this is cleaner and easier
366 to work with in proxies and the like. This facility can be used in
367 yaz-client using new command setscan which takes a result set as first
368 argument, start position (APT) as second.
370 Changed decoding of SRU XML packed records to deal with servers that
371 have recordData with XML data with multiple root nodes. Also make
372 comparison for recordPacking case insensitive. Again, one server
373 returns "XML" where others return "xml".
375 For SRU responses allow Content-Type application/xml as well as text/xml.
379 Fixed bug in character set conversion of BER strings. Bug introduced
384 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
386 For OID class, use oid_class consistently.
388 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
391 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
392 character set for bibliographic information interchange". By Giannis Kosmas.
394 Added documentation on new OID API.
398 Changes to generic frontend server interface: added new member
399 'query_charset' for bend_initrequest structure. A backend init handler
400 should set this member to its native character set for query terms.
401 When defined, the frontend server logic will announce this character set
402 to a client if the negotiationModel bit is set by the client. All server
403 implementors are encouraged to specify this. If a backend server does not
404 specify this a warning is issued using yaz_log(YLOG_WARN,..).
406 Added CCL utility to remove terms (stop words) from resulting RPN
407 tree. This is handled by functions with prefix ccl_stop_words_ .
409 New ZOOM C option, "rpnCharset", which allows client-side conversion of
410 terms in RPN queries.
412 Clean-up the CCL API. Moved some internal structures from ccl.h to
413 private header cclp.h. Changed ccl_parser_create so that a Bibset must
414 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
415 This is replaced by ccl_parser_find_str which takes a string instead.
417 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
418 libyaz.la is the core of YAZ except the generic frontend server and
419 does not depend on POSIX threads anymore. libyaz_server.la is the
420 generic frontend server facilities and uses POSIX thread functionality
421 if available. The libyaz.la no longer depends on POSIX threads because
422 the number of global structures is limited. NMEM no longer re-uses blocks
423 between threads ; it simply free's memory immediately but allocates in
424 "large" chunks as usual. We don't expect any performance penalties
425 because of this. The yaz_log system is still using a global log_level so
426 caution must be taken when modifying it with yaz_log_init_.. +
427 yaz_log_mask_str. This, however, should not cause any trouble because
428 these functions are called during initialization of application code
429 anyway. `yaz-config --libs server` returns libs for server applications;
430 `yaz-config --libs` returns libs for non-server applications.
432 New OID database - with public definitions in oid_db.h. Removed old OID
433 database including the head oid.h and definitions such as enum oid_value
434 and struct oident. The new OID database uses the same string names as
435 before but the 'protocol' is gone. There are now only two representations
436 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
437 converts from string to OID; functions with prefix yaz_oid_to_string
438 converts the other way.
440 Change to emit_term() in CQL-to-PQF query translation: when a term has
441 the /regexp relation modifier, do not process it for leading and
442 trailing "^" and "*", which have quite different meanings in regular
445 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
446 write handlers no longer carries a 'last' parameter. This will make
447 yaz_iconv flush "less" characters. A flush is performed by call to
448 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
450 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
451 removed, because function yaz_query_to_wrbuf does the same.
453 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
454 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
456 Deprecated MARC utility functions removed.
458 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
461 Branch split: YAZ_2_1_55_branch
463 --- 2.1.54 2007/03/16
465 Fix to ZOOM-C so that transparent reconnection is properly handled on
466 connections that are in asynchronous mode.
468 Fixed compilation on OpenBSD 4.0.
470 Large strings in GRS-1 records are now properly displayed in yaz-client.
472 Added character conversion support for "advancegreek"; based on patch from
475 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
476 sequence is met. Before the error was not set so it would be unknown.
478 Adjust yaz-marcdump MARC reader so that it skips until record separator
481 --- 2.1.52 2007/03/07
483 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
484 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
485 fd_set structure used as a bitmask for the FDs to be selected on.
487 Using ACX_PTHREAD macro to check for POSIX threads.
489 Fixed have-vsnprintf check.
491 --- 2.1.50 2007/02/23
493 Fixes for configure on BSD. Bug #900.
495 Added snprintf/vsnprintf wrappers for systems that don't have
496 limits (heavens forbid).
498 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
499 created before all previous tasks were completed and removed from the
500 task queue, the new task could be removed by a mistake.
502 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
504 Implemented pass-through CQL-to-PQF conversions. Bug #861.
506 Fixed bug #832: Problem with MARC/charset in yaz-client.
508 Fixed bug #668: save command line history for yaz-client.
510 Fixed bug #830: pkg-config support.
512 --- 2.1.48 2007/01/23
514 Extended ZOOM result set options with two options that may be read by
515 a client: resultSetStatus and presentStatus with values as specified for
517 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
519 Fixed bug #827: Using SSL fails on Debian etch.
521 Fixed bug #826: Weird looking chars for set of MARC records.
523 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
524 that is treated as an ItemOrder with itemRequest being an XML document
525 external. The value of "doc" is the content.
527 Extended the GFS search facility. New member of bend_search_rr
528 'estimated_hit_count' signals that hits is known to be an estmate
529 (higher or lower than real hit count). New member 'partial_resultset'
530 signals that the search was partial (hit count is lower or equal than
531 real hit count). For Z39.50, the information is stored in resultSetStatus
532 member of SearchResponse APDU. For SRU, the information is signalled
533 via SRU diagnostic 59: "Result set created with valid partial results
536 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
538 --- 2.1.46 2007/01/13
540 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
542 Added ZOOM_connection_peek_event.
544 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
545 the following new functions:
546 ZOOM_event_nonblock, ZOOM_connection_process,
547 ZOOM_connection_get_{socket,mask,timeout},
548 ZOOM_connection_fire_event_{timeout,socket}.
549 The existing blocking event handler, ZOOM_event, is a wrapper for the
550 + blocking ZOOM_event_sys_{poll,select}.
552 Implemented function ccl_xml_config which parses XML version of CCL
553 configuration (bug #798).
555 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
557 Added timings utility (yaz/timing.h)
559 --- 2.1.44 2007/01/03
561 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
564 Fixed bug #779: Rotation of apdu.log fails.
566 Fixed for character set conversions:
567 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
568 Honor G1 set in MARC-8 decoding.
570 --- 2.1.42 2006/12/17
572 Fixed bug #775: char conversion does not handle Alternative UTF-8
575 Implemented function yaz_marc_read_line which parses MARC line format
576 records. There is a wealth of formats out there. So far, this function
577 reads line records produced by yaz_marc_write_line.
579 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
580 more generic and easier to remember(!) options: -i format and -o format
581 which specifies input format and output format respectively - where
582 format is one of "marc", "marcxml", "line", "marcxchange".
584 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
585 does not print anything except warnings for records.
587 For yaz-marcdump, added support for MARC split into files (-s) with a given
590 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
591 spec, at http://www.loc.gov/standards/sru/record-update/
592 This has changed the binary layout of the following structs:
593 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
594 bend_update_rr . Patch by Ko van der Sloot.
596 Added GFS utility function bend_assoc_is_alive which returns 1 if
597 association is still alive (client is connected); 0 otherwise (client
598 closed connection). This allows busy servers to stop working for
601 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
602 been a separate piece of software. This version of ziffy has been modified
603 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
605 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
607 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
608 Client code may now interrogate options such as "init_opt_sort" to
609 find out whether the server claims to support various options.
611 --- 2.1.40 2006/11/27
613 Added utilities yaz_{set,get}_esn to set/get element set name from
616 Removed the build of libyazthread.la. The libyaz.so is the threaded version
617 of YAZ and has been so since YAZ 2.1.10.
619 Implemented ZOOM_record_error which returns error information for
620 record (surrogate diagnostic).
622 --- 2.1.38 2006/10/31
624 Updates for SRU Update by Ko van der Sloot:
625 1. Changed name from "operation" to "action"
626 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
627 versions in the code, marked as 'backward compatible'.
628 3. Added diagnostics for SRU Update.
630 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
632 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
634 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
636 For GFS, fixed problem with SRU diagnostic 'First record position out of
637 range' being issued for 0 hits.
639 zoomtst10 part of Windows Build.
641 --- 2.1.36 2006/10/13
643 Implemented yaz_filepath_comp which splits a path into file path
644 components (required by Zebra 2.0.3+).
646 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
647 BSD inspired license until now so this should not have any real impact on

650 Fixed bug #687: Missing log lines.
652 Fixed bug #678: CQL to PQF translation does not preserve double-quote
655 Fixed bug #689: SRU diagnostics to be added.
657 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
658 whether a connection is idle (no more work do do).
660 --- 2.1.34 2006/10/04
662 Change type of optval from long to int for invocation of setsockopt with
663 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
665 Added support for specifying the max log file size for the Generic
666 Frontend Server. The size is given with option -r.
668 --- 2.1.32 2006/09/21
670 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
672 --- 2.1.30 2006/09/17
674 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
677 Fixed bug in Generic Frontend Server that could cause a server to stop
678 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
680 For the generic frontend server, the maximum record size is used as maximum
681 size of incoming packages (SRU + Z39.50). The value until was previously
682 only used in Z39.50 Init negotiation and, later, in a session controlled
683 sizes of records returned. This is controlled using -k option. It can be
684 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
686 --- 2.1.28 2006/09/04
688 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
691 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
693 New option for yaz-marcdump -lpos=value which allows setting a portion
694 of MARC header to a certain value.
696 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
698 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
699 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
701 --- 2.1.26 2006/08/15
703 Fixed problem with SRU mode type (soap, get, post) for yaz-client
706 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
708 --- 2.1.24 2006/08/08
710 Fixed MARC ISO2709 encoding routines to deal with character set
713 Minor changes to GFS logging. Database included in search request log
716 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
717 cached/multiple records.
719 Shared libraries are built by default on Unix+configure.
721 Changed cql2pqf transformation to use a different evaluation order. The
722 new order is: always, relation, structure, position, truncation, index
723 and relationModifier. Old order was: always, relation, relationModifier,
724 structure, index, position, truncation. Note that the the latter ones
725 override former ones for identical attributes.. The new scheme means that
726 it is possible to override any existing attribute with a relationModifier.
727 And also that it is possible to override everything for the index rule
728 (except the ones listed in relationModifier). No order is perfect but this
729 one, we believe, covers more real cases.. The "always" should have been
730 called "default", since the attributes there can be overridden with all
733 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
734 compilation phase, but also for yaz-config --cflags output. This allows
735 us to have public headers with Libxml2 stuff in them . It should also,
736 eventually, make Libxml2 checks redundant in packages using YAZ, such
739 --- 2.1.22 2006/06/15
741 Changed SRU update structure bend_update_rr so that SRU diagnostics are
742 stored in uri, message and details.. Previously diagnostics were stored
743 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
744 compatibility.. but he's probably the only one affected, so.
746 Added support for CCL, compiled on the client side, in ZOOM-C. This
747 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
748 input; the resulting query objects can be used for for searching with
749 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
751 YAZ' configure searches for OpenSSL by default.
753 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
754 SL_CTX_use_certificate_file. See
755 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
756 for more info. Thanks to Ko van der Sloot.
758 --- 2.1.20 2006/06/02
760 Bug #600: SRU GET, POST support for yaz-client. Introduced
761 command 'sru' which selects method SOAP/GET/POST.
763 Allow missingValueAction to be specified for the sortspec string -
764 function yaz_sort_spec. By default, the missing value action is null.
765 Use ! to specify "abort". Use = followed by stringvalue to specify default
768 Ensured that Present-handler (if defined) is called in GFS before any call to
769 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
770 searchRetrieve requests.
772 Documentation for YAZ is now based on the Docbook XML/XSLT using
773 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
774 is no longer depending on jade/openjade or docbook-to-man scripts.
775 PDF is no longer part of the distribution - but can optionally be
776 made using DSSSL/jadetex or FOP.
778 Added retrieval handling support in Generic Frontend Server to support
779 conversion between MARC/XML as well as XSLTtransforms. See
780 etc/yazgfs.xml for an example.
782 Added Authentication support to Generic Frontend Server in SRU
783 mode. Authentication using HTTP Basic is supported, as is the use
784 of 'x-username' and 'x-password' parameters in the request itself.
786 Added support for a new character set MARC8s identical to MARC8 except
787 that it converts combined characters to single Unicode characters in the
788 Latin-1 range (when possible).
790 --- 2.1.18 2006/04/24
792 ASN.1 compiler 0.4: generates brief Doxygen file header for
793 generated .h/.c files.
795 Utility yaz_iconv now supports conversion to MARC-8.
797 New facilities for the MARC module. The reading - and writing of
798 content are separate methods for the yaz_marc_t handle. The following
799 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
800 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
801 format). Write functions have prefix yaz_marc_write_.. The existing
802 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
803 available. Removed support for OAI-MARC and simplexml (not the
804 simplexml from PHP5).
806 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
807 to be returned for this connection.
809 --- 2.1.16 2006/03/31
811 Allow multiple languages and charsets to be specified with
812 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
813 negcharset iso-8859-1,utf-8
815 Translation of proximity nodes from CQL into PQF now works.
817 Moved to automake 1.8, 1.9.
819 Added function yaz_log_set_handler which allows a log handler to be
820 installed. This handler will be called for all log messages. Output
821 to file is also produced; but that can be disabled by passing NULL
822 fname to yaz_log_init_file.
824 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
826 For SRW (including GFS), accept application/soap+xml as content-type
829 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
830 produces NO stylesheet reference even if a default stylesheet is specified
833 --- 2.1.14 2006/03/14
835 Updated Windows package to include yazd.dll + yazd.lib for the
836 Development component.
838 If the environment variable YAZ_LOG is set, then it is used as a
839 string indicating the default level of logging to use if not
840 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
841 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
842 used as before. So, for example, to omit warnings from YAZ logging,
845 cql_transform() now map structure and other attributes before indexes,
846 so that index-specific structures and other attributes can override
847 defaults. So now a combination of mapping specifications such as:
849 index.dc.date = 1=date-modified 4=5
850 does the right thing.
852 cql_transform() now also respects the "always" mapping specification,
853 which establishes an initial set of attributes to be used for all
854 terms except where overridden by more specific attributes associated
855 with the index, relation or modifier.
857 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
858 which mode to use; one of "post", "get" or "soap" (SRW, default).
860 Fixes for yaz_iconv routines: changed trie-based character set conversions
861 to use only non-negative values for bit fields due to Sun's C compiler not
862 supporting negative values.
864 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
865 sequences where not read correctly. Fix by Rustam Usmanov.
867 Updated win/makefile to use options, settings which makes things
868 compile with VS C 2005.
870 --- 2.1.12 2006/02/01
872 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
874 In ZOOM socket code, use select instead of poll on MacOSX.
876 ZOOM-C now support client-side compilation of CQL into RPN that is
877 sent to the server, enabling CQL to be used against all Z39.50
878 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
879 ZOOM_query object, and submit it using ZOOM_connection_search().
880 The CQL-to-RPN translation uses a configuration file, the name of
881 which must be specified in the Connection's "cqlfile" option.
883 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
884 function, which takes as its start-term parameter a ZOOM_query object
885 (which may have had either CQL or RPN set into it).
888 --- 2.1.10 2005/11/29
890 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
891 GFS to support this as well. Backend handler, bend_srw_update, does the
892 update work. Code contributed by Ko van der Sloot.
894 Allow retrieval of Search Result-1 information in ZOOM by the use of
895 options that are attached to a result set. ZOOM documentation updated
898 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
899 UTF-8 conversion. Patch by Raj Patel.
901 Added option -m to GFS to control formatting of timestamps in log file.
903 Added 'exit' as synonym for 'quit' in yaz-client
905 Added support for specifying SRW resultSetId + resultSetIdleTime in a
906 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
907 for the new members. Patch by Ko van der Sloot.
909 Added support for SRU POST. It is supported for content-type
910 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
912 Do not build the separate Multi-threaded (MT) library libyazthread.la.
913 Instead make the library libyaz.la multi-threaded. Threading as a whole
914 can still be disabled by configure option --disable-threads. Previosly,
915 with older GLIBCs there were problems with MT libs under Apache. This
916 has now been fixed a long time ago.
918 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
921 CQL module modified to be case insensitive for relations/indexes/operations.
923 Fixed bug in CQL transform code: incorrect value relationModifieder
926 Added 'show all' command for yaz-client which retrieves all results
929 Added new yaz-client, xmles, which takes a (private) OID and
930 a document to be sent as an extended service request.
932 Describe new yaz-client commands wait_response and set_auto_wait.
934 Increase TCP/IP listener backlog from 3 (which I am guessing was
935 copied from the SunOS manual entry way back when) so SOMAXCONN, so
936 that the socket will queue as many incoming connections as it's able
937 to handle ongoing connections. In other words, it will never now
938 refuse a connection that it would be able to handle merely because
939 it's not got around to accepting() enough of the pending connections
940 yet. This is the behaviour anyway under Linux, where the listen()
941 argument is ignored; but not under BSD and on systems such as
942 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
943 YAZ-based servers should now be uniform across operating systems in
946 yaz-marcdump uses 64-bit file access on some systems. This is enabled
947 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
948 This allows yaz-marcdump to read large MARC batches (>2 GB).
950 Modified all YAZ source files - except the source which is auto-generated
951 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
954 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
955 corresponding to the existing *_setl() function. These allow option
956 values containing arbitrary valuues.
958 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
959 ZOOM_resultset_sort() in new applications. Its behaviour is identical
960 except that it returns an indicator of whether or not the sort
961 criterion was accepted (0 for OK, -1 for invalid).
965 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
966 MARC output rather than returning "new" buffer.
968 yaz-client warns about unknown init options.
970 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
974 Added support for SRW sort in Generic Frontend Server. Patch
975 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
976 sortKeys - or NULL if none is provided.
978 Fixed bug #307: It was impossible to specify indefinite/no timeout
979 for ZOOM_event. Special timeout value -1 now means indefinite timeout
982 Added support for multiple languages and charsets to be specified in
983 ZOOM. Each charset/language is separated by a blank. If negotiation is
984 in effect in init-response, Option
985 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
986 Code based on patch by Vasiliy Osadchuk.
988 Fixed bug #306: infinite recursion that occurred when calling
989 yaz_log_level_init as the first call (before other log level or
992 Fixed bug in scan handling in front end server: if preferred-Position-In-
993 Response was non-present, a NULL pointer referece was performed.
997 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
998 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
999 now defined for all those error codes. So instead of putting 109 in
1000 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1001 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1003 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1006 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1008 Program yaz-client now exits and produces an error message if multiple
1009 Z39.50 servers are specified on the command line (none or one allowed
1012 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1015 --- 2.1.2 2005/03/16
1017 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1019 Fixed bug #272: Preserve spacing for CCL terms.
1021 --- 2.1.0 2005/03/14
1023 Added support for virtual hosts and multiple backend servers for
1024 the YAZ frontend server. The configution is XML based and
1025 support specificition of CQL to RPN mappings and explain information.
1026 See section "Virtual Hosts" in the YAZ manual.
1028 Extended OPAC display utility. OPAC display utility renders
1029 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1030 to supplement yaz_marc_decode_wrbuf.
1032 Fixed a bug in MARC decoder that could caused it to crash for some
1033 invalid MARC records. More diagnostics and warnings where added in
1034 XML output (warnings, etc are stored in comments).
1036 --- 2.0.34 2005/02/08
1038 Fixes for UNIX domain sockets. Bug #261.
1040 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1042 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1043 Added yaz_marc_subfield_str which defines subfield lead string which is
1044 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1045 yaz_marc_endline_str which defines end of fields string used in
1046 YAZ_MARC_LINE format. Default string is newline.
1048 Experimental support for MarcXChange. This format can be produced
1049 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1050 http://www.bs.dk/standards/MarcXchange.xsd
1052 Added yaz-client commands scansize that sets maximum number of
1053 entries to be returned by scan.
1055 --- 2.0.32 2005/01/11
1057 Added support for SRW scan in yaz-client and Generic Frontend Server.
1059 * Added whereInList member to SRW Scan Term.
1061 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1063 Fixed NMEM system to return aligned blocks on the smallest boundaries
1064 that are suitably aligned for all possible types on the particular
1065 architecture YAZ is being built for.
1067 --- 2.0.30 2005/01/04
1069 Fixed numerious warnings that was issued with newer versions of GCC.
1071 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1072 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1075 Make YAZ Generic Frontend Server slightly faster.
1077 Enhance (and reduce) logging for Generic Frontend Server.
1079 Revert YAZ log system so that it flushes every write operation
1080 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1082 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1083 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1084 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1085 will effectively disable old definitions.
1087 --- 2.0.28 2004/11/09
1089 Added yaz_log_time_format which specifies log format using
1092 Added yaz_log_module_level which returns mask for a module. Value
1093 is non-zero mask a if module is enabled; zero if disabled.
1095 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1096 in include/yaz/cql.h.
1098 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1100 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1102 Fixed bug #172: RPM builds does not enable SSL.
1104 Doxyfile.in part of dist. Doxyfile generated by configure.
1106 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1107 are given and the corresponding component does not exist.
1109 Extend CCL documentation in YAZ reference. Describe r=r.
1111 --- 2.0.26 2004/10/01
1113 Fixed MARC->MARCXML conversion to properly deal with
1114 fields, subfields, indicators having non-ASCII characters.
1116 Fixed MARC->MARCXML conversion so that ASCII control characters
1117 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1120 Added YAZ GFS support for conversion from Z39.50 surrogate
1121 diagnostics to SRW surrogate diagnostics.
1123 Bug fix: YAZ GFS did not return schema in explainResponse.
1125 --- 2.0.25 2004/09/30
1127 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1128 now converts recordSchema to elementSetName as well as schema URI.
1130 Fixed bug in COMSTACK that prevented HTTP request packages from being
1133 --- 2.0.24 2004/09/29
1135 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1136 does not require white-space before and after the dash in a range, e.g.
1137 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1140 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1141 due to new GCC removing "redundant" code.
1143 Added yaz-client commands scanpos and scanstep that sets preferred
1144 position and step-size for scan.
1146 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1148 Added CCL utility ccl_qual_buf which parses one or more CCL
1149 spec lines in a buffer.
1151 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1152 of name and value - ignoring empty lines and comments.
1154 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1156 Added odr_get_element_path which returns current element path for an
1157 ODR handle. This utility is useful in error handling or user-defined
1160 Added ODR_PRINT utility odr_set_stream which is is a more generic
1161 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1162 to a write function and pointer to close function. The close function - if
1163 non-NULL - will be called during odr_destroy.
1165 Fixed bug in CCL parser where truncation char was not removed from
1166 right side when truncation=both was in effect.
1168 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1171 --- 2.0.23 2004/08/11
1173 Fix buffer overrun in CQL parser when dealing with proximity (%).
1175 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1176 to UTF-8/UCS conversion is now only based on codetables.xml.
1178 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1180 --- 2.0.22 2004/08/06
1182 Add support for more "commit changes" in ZOOM (uses Extended Services).
1184 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1187 Yet another small fix for configure of SSL.
1189 --- 2.0.21 2004/05/14
1191 Fix SSL libs for configure when --with-openssl=DIR is given.
1193 --- 2.0.20 2004/05/10
1195 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1197 SSL comstack now uses yaz.pem certificate file on server side
1198 by default. Certificate filename can be configured by calling
1199 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1201 Fix bug regarding multiple calls to ZOOM_connection_connect.
1203 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1205 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1206 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1208 ZOOM now allows inspection of X509 peer certificate for verification.
1209 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1211 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1212 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1213 as "modular" but it simplifies things.
1215 Added cs_get_peer_certificate to that returns peer X509 PEM.
1217 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1218 NULL if SSL is unavailable.
1220 Documentation about MARC decoding tools.
1222 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1224 --- 2.0.19 2004/03/30
1226 Rename CHANGELOG to NEWS to follow GNU style packing.
1228 Fix bug with missing initialization of member in init_diagnostics.
1229 This bug affects threaded version of GFS server.
1231 --- 2.0.18 2004/03/20
1233 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1236 Ensure zlib.dll is packed with Windows install.
1238 --- 2.0.17 2004/03/17
1240 Fix encoding of xsd:string to use text instead of CDATA.
1242 Fix endless loop in CQL parser with unbalanced ".
1244 Use a more compact way to store MARC-8 conversion tables.
1246 --- 2.0.16 2004/03/16 Debian only
1248 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1251 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1256 --- 2.0.15 2004/03/01
1258 Another fix for decoding of XML packed records.
1260 --- 2.0.14 2004/02/25
1262 Fixes for Chunked encoding. White space not ignored after length spec.
1264 Update NS and use default NS for SRW diagnostic elements.
1266 --- 2.0.13 2004/02/23
1268 Implement ZOOM_resultset_cache_reset which resets record cache.
1270 Implement ZOOM_resultset_sort which sorts a result set.
1272 Implement chunked HTTP transfer.
1274 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1276 --- 2.0.12 2004/02/16
1278 Added member 'schema' to bend_explain_rr structure so that backend
1279 can specify explain record identifier. Defaults to Zeerex 2.0.
1281 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1283 --- 2.0.11 2004/02/16
1285 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1288 Added init command for yaz-client which sends "extra" init request.
1290 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1291 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1293 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1295 Make ZOOM error code for "invalid query".
1297 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1299 --- 2.0.10 2004/02/05
1301 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1304 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1306 Added option -p <file> to make Generic Frontend Server to write PID file.
1308 Added option -D to put Generic Frontend Server in background on its own.
1310 Make ZOOM C recognize option "password". If unset, "pass" is used
1311 (for backwards compatibility).
1313 Fixed a bug in Generic Frontend Server that could make it crash if a
1314 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1317 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1318 Must be issued before open, in order to be in effect.
1320 --- 2.0.9-6 2004/01/12 Debian/Windows
1322 Make the SRU server more picky WRT unknown params, etc.
1324 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1326 New YAZ client command, options, that sets Z39.50 options.
1328 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1329 options from a string of tokens (one token for each option bit).
1331 Update SRW diagnostic code messages.
1333 --- 2.0.9-5 2004/01/07 Debian/Windows
1335 Handle user defined stylesheet for SRW/SRU.
1337 --- 2.0.9-4 2004/01/06 Debian/Windows
1339 Fix bug in decoding of Content-Length.
1341 --- 2.0.9-3 2004/01/06 Debian/Windows
1343 Fix a bug with decoding of XML packed records.
1345 --- 2.0.9-2 2004/01/05 Debian only
1347 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1349 Fix bug in SRW/SRU diagnostics decoding.
1351 --- 2.0.9 2004/01/05
1353 Fixed bug in Generic Frontend Server which could drop records exceeding
1354 preferred message size. Reported and fixed by Irina Dijour.
1356 Fixed calculation of package size for structured records in Generic
1357 Frontend Server. Reported and fixed by Irina Dijour.
1359 Fixed namespace for SRW/SRU diagnostics.
1361 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1363 --- 2.0.8 2003/12/22
1365 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1366 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1369 CQL changes to reflect recent changes to the specification:
1370 * Documentation talks about context sets instead of index sets.
1371 * Documentation talks about indexes instead of qualifiers.
1372 * The CQL-to-PQF transformer's configuration file now uses
1373 "index.set.name = <attributes>" instead of the old form
1374 "qualifier.set.name = <attributes>". (Both forms are still
1375 understood but the latter is deprecated.)
1376 * CQL terms with no explicit index specified are now interpreted as
1377 cql.serverChoice instead of srw.serverChoice (which of course
1378 behaves exactly the same.)
1380 --- 2.0.7 2003/12/16
1382 MARC conversion can now generate ISO2709 output in another
1383 character set. yaz-marcdump uses this facility if you invoke it
1386 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1387 functions from there can be used from C++.
1389 --- 2.0.6 2003/12/04
1391 Frontend server now transfers memory from decoded packages to stream
1394 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1395 references to show up.
1397 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1398 the ZOOM Abstract API. The older names for the same options are still
1399 also supported for the benefit of old applications.
1401 ZOOM-C supports "implementationId" and "implementationVersion" options
1402 to go along with "implementationName". These allow the user code to
1403 specify identification strings to be sent to servers.
1404 Add OID for the new ExtLite attribute set.
1406 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1407 as requested/supplid by Ere Maijala <ere@atp.fi>
1409 For generic frontend server, reverse the order of
1410 "toolkit-supplied / application-supplied" strings sent as implementationId,
1411 Name and Version. Also, remove the spaces around the slash. This brings
1412 the GFS in line with the behaviour of ZOOM-C on the client side.
1414 Add function ZOOM_scanset_display_term.
1416 yaz-client shows scan displayTerm if present.
1418 Utility yaz-iconv is now installed by default along with the man page
1421 Extend configure check for OpenSSL to use pkg-config where available (such
1424 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1425 server to specify uid/gid/mask for socket using the format
1426 unix:[user=uid,][group=gid,][umask=mask,]file=path
1427 If file= is omitted the existing format is assumed, e.g.
1429 in which case the mask is 0666 (rw for everybody).
1431 Major restructure of YAZ source. All source in libyaz is in src directory.
1432 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1433 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1435 Added man page for utility yaz-marcdump (used to be called marcdump).
1436 yaz-marcdump is installed by 'make install'.
1438 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1439 of incoming package failed.
1441 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1443 Change prototype of odr_perror: add const to message string.
1445 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1447 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1448 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1449 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1450 DNS lookup. There should not be any compatibility problems with this
1451 assuming that blocking=1 or 0 is used.
1453 Fix bad reference in UNIX comstack in function cs_addrstr.
1455 Fix for compilation on AIX.
1457 The generic front-end server (server/seshigh.c) now supports returning
1458 Init diagnostics to the client in User-information-field, in
1459 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1462 --- 2.0.4 2003/09/04
1464 Allow any CQL relation (not just all,any,exact,scr).
1466 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1467 that features the same UI.
1469 Implemented command update0 in YAZ client which is equivalent to
1470 update but uses old of Ext Update ASN.1.
1472 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1473 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1474 Previously no OID was used for this info.
1476 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1477 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1478 returns 'malformed search term' otherwise.
1480 SortResponse member resultCount now set to NULL in sort handler of
1483 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1486 Add three new utility functions for translating OIDs between various
1487 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1488 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1489 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1490 char *oid_to_dotstring(const int *oid, char *oidbuf);
1491 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1493 Reverted modifications for ES Update definition for z_IU0Update
1494 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1495 is back to YAZ 2.0.2.
1497 String value attributes for CCL parser.
1499 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1500 which their FirstSearch server returns in Init responses, sometimes
1501 carrying useful diagnostic information when Init fails. This has the
1502 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1503 "z39.50/oclcui.asn", where its definition is somewhat different from
1504 what OCLC document on their web-site, as required to interoperate with
1507 Support for anonymous authentication in yaz-client. Use the command
1510 * Fix the OID of the Index Data-local "admin" Extended Service from
1511 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1512 the 1000, which indicates a locally-defined OID, was a mistake.
1514 --- 2.0.3 2003/06/20
1516 Fix CCL directive @case handling so that it affects string match for
1517 both CCL keywords and qualifiers.
1519 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1520 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1521 Decoder has been updated with ASN.1 changes as listed in
1522 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1523 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1524 z_IUUpdate, remains unchanged.
1526 ZOOM_record_get may now return a record in a specific character set.
1527 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1528 "from" is the character set of record as returned by target. "to" is
1529 the character set to be returned. If omitted, "to" is UTF-8.
1531 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1533 New ODR utility, odr_getelement, which returns name of element for
1534 which encoding/decoding failed.
1536 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1537 in cases where a required element was omitted.
1539 Bug fix: some MARC8 sequences were not converted.
1541 New ZOOM option "step" which specifies number of records to be
1542 retrieved in one chunk. Used in conjunction with "start" and "count".
1544 SRW support for yaz-client. Use scheme http: to use it, e.g.
1547 yaz-client no longer does (un)intelligent character set conversions
1548 by default. Can be enabled with charset and marc_charset commands.
1550 xmalloc trace fix for 64-bit systems such as DEC alpha.
1552 Solaris 2.6 compile fix.
1554 New function, cql_strerror() translates SRW error codes, as returned
1555 by cql_transform_error(), into human-readable English strings. Used
1556 in yaz-client diagnostics when appropriate.
1558 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1559 converts it into a type-1 query which is sent to the server. This
1560 makes CQL available for use with all Z-servers, as opposed to the tiny
1561 minority that can handle CQL queries themselves.
1563 --- 2.0.2 2003/04/28
1565 New Debian package layout similar to the Redhat Package layout.
1567 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1568 and search result respectively.
1570 --- 2.0.1 2003/04/25
1572 Redhat package is now several packages: libyaz (runtime libraries),
1573 libyaz-devel (development and documentation, and yaz (utility programs).
1574 Package spec file by Morten Bogeskov.
1576 New member 'schema' in struct bend_fetch_rr which the name of requested
1577 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1578 handler MAY set this to reflect the schema of the returned record.
1580 New member 'display_term' in struct scan_entry. GFS now sets member entries
1581 and allocates scan entries to be filled by user scan handler. In previous
1582 version, entries member was allocated by the scan handler. That still works,
1583 but the GFS will ignore member display_term - assuming it was NOT set by
1584 the handler. The fact that the GFS now allocates the entries both allows
1585 for new members and makes a scan handler easier to write.
1587 Fix CQL lex buffer overflow.
1589 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1590 SRU default recordPacking is string.
1592 SRU protocol support for frontend server.
1594 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1596 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1598 Added scan for the ZOOM shell (zoomsh).
1602 * String Identifers for Schemas (Amendment 5).
1603 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1604 Old definition for schema
1605 Odr_oid *schema; /* OPT */
1610 Z_InternationalString *uri;
1611 #define Z_Schema_oid 1
1612 #define Z_Schema_uri 2
1615 * resultCount parameter to Sort Response (Amendment 1).
1616 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1618 Support for SRW 1.0 over HTTP. This is an optional feature and
1619 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1622 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1623 on the same port. SRW SearchRetrieveRequests are mapped
1624 to bend_init,bend_search,bend_fetch,bend_close.
1626 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1628 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1629 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1631 ZOOM connections are SRW based if schem http is used for hostname
1632 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1633 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1635 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1636 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1637 distance=n, order=true/false, relation=le, prox unit=word. If
1638 n is omitted, distance 1 is used.
1640 Fixed problem with C compiler include path in wrong order.
1642 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1643 on Solaris. Patch from Ko van der Sloot.
1645 New MARC decode API. All new functions operate on a yaz_marc_t
1646 handle. The most important new functions are: yaz_marc_create,
1647 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1648 decode and destroy respectively. Decoder can produce formats
1649 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1650 include/yaz/marcdisp.h.
1652 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1653 to UTF-8, UCS-32, wchar_t or Latin-1.
1655 * Prototypes for yaz_iconv_-functions moved to separate header
1656 include/yaz/yaz-iconv.h.
1658 Make a few private functions 'static' in unix.c. This prevents
1659 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1661 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1662 are set when Init Response is received.
1664 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1665 but returns diagnostic set as well.
1667 New function yaz_strerror which is a portable wrapper for
1668 strerror/strerror_r/GetLastMessage.
1670 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1671 is returned for MARC. If type is "oai", then OAI MARC is returned.
1673 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1676 --- 1.9.2 2002/11/26
1678 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1680 Fix bad race conditions on SIGTERM and terminate gracefully in
1683 Move retrieval (data1) module to Zebra since nobody seems to be
1686 Add GRS-1 render for ZOOM using same format as yaz-client.
1688 --- 1.9.1 2002/10/05
1690 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1692 Fix broken ESpec handling in data1 module.
1694 SGML reader parses comments and makes them part of the data1 tree.
1696 Added several type casts so that YAZ compiles as C++ code.
1698 ZOOM didn't handle PDU encoding failures properly.
1700 Added more Bib-1 diagnostics (approved extensions).
1702 GNU configure: better check for iconv.
1704 More portable use of accept, getpeername. Check for socklen_t. Use
1705 int/size_t if socklen_t is not defined.
1709 PQF parser rejects bad queries - including those with extra
1710 characters in them. PQF parser used to silently ignore that.
1711 Cleaner API for PQF added, which allows you to get detailed
1712 error information for bad queries (see yaz/pquery.h).
1714 Fixed bug in ZOOM_record_get for type "database".
1716 Implemented mini iconv library supporting conversions between
1717 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1719 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1721 --- 1.8.9 2002/08/20
1723 Fixed ZOOM C record cache so that preferredRecordSyntax and
1724 elementSetName is used to check for already fetched records.
1726 --- 1.8.8 2002/08/02
1728 Added three members in bend_initrequest structure to facilitate
1729 character set negotiation.
1731 Fixed a bug in frontend server that could cause indefinite
1732 loops under rare conditions.
1734 Revised character set utilities (charneg.h) so that encoding
1735 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1737 For PQF, directive @term <type> sets term type for Scan/Search.
1738 Here <type> is general, string, numeric, null. The term type
1739 is inherited - just like @attr.
1741 New call odr_set_charset that sets character set conversion for
1742 international-strings on a ODR stream. Prototype is:
1743 int odr_set_charset(ODR o, const char *to, const char *from);
1744 The InternationalString is still represented as C string in YAZ
1745 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1746 won't). On the protocol level, you can use any encoding.
1748 Support for UNIX sockets in ZOOM.
1750 Solaris recv sometimes returns errno == ENOENT. It is treated as
1751 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1753 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1754 both client and server. Code by Morten Bogeskov.
1756 --- 1.8.7 2002/05/22
1758 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1759 that they can be used directly from Visual Basic. You must recompile
1760 your windows APP if you're using ZOOM.
1762 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1763 Commands "lang" and "charset" sets language and character set respectively.
1764 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1765 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1767 Attributes from multiple CCL fields may be OR'ed rather than merged
1768 using directive "@field or". Fields are still merged by default -
1769 equivalent to "@field merge".
1771 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1774 Fixed bug in zget for parameter ExtendedServicesResponse.
1778 --- 1.8.6 2002/03/25
1780 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1782 Client displays USR.1:SearchResult-1 (hits per term).
1784 Additional Search Info for search in Generic Frontend Server.
1786 Fixed CCL parsing of "field=s".
1788 WIN32 installer - using the excellent NSIS software from nullsoft.
1790 Fixed CCL parsing of "field = - <number>".
1792 Added function yaz_marc_decode that decodes MARC for line mode
1793 display or XML (similar to that used by JZKit).
1795 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1796 Z39.50. But ISO/ILL was, however.
1798 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1799 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1801 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1802 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1804 --- 1.8.5 2002/02/03
1806 New YAZ client features: Command completion and new commands:
1807 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1808 Code provided by Jacob Poulsen.
1810 New call oid_trav, that visits all registered OIDs via callback.
1812 Function ZOOM_record_get now returns const char pointer rather than
1813 void pointer. It saves a lot of type casts.
1815 For YAZ client, command "auth" now allows you to set authentication
1816 in IdPass style. It is enabled when three tokens are given - order
1817 is user, group and password.
1819 Fix memory leaks in MARC record handling for ZOOM.
1821 New option for YAZ client, -k <kilobytes> that sets
1822 maximum record size. Similar to -k option for generic frontend
1823 server and yaz-ztest.
1825 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1827 Prefix query parser reports "fail" when bad attribute set is given.
1829 Fix in MARC decoder. Proximity logging. Fix for attribute set
1830 in scan handler for server. Patches by Shigeru Ishida.
1832 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1835 Configure option --with-openssl=<dir> now works when a directory is
1836 specified. Patch provided by Morten Bogeskov.
1838 New option for YAZ client, -u <auth>, that sets authentication.
1840 ZOOM fix: error information was sometimes "missing", since error
1841 was cleared/reset too when it shouldn't.
1843 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1845 --- 1.8.4 2002/01/04
1847 Scan for ZOOM API. New object ZOOM_scanset. New functions
1848 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1849 ZOOM_scanset_destroy.
1851 New ZOOM function, ZOOM_connection_last_event, that returns type
1852 of last event (such as "receive data", "send data", "apdu received",
1855 New ZOOM option, schema, that specifies schema for retrieval.
1857 New CCL feature. Qualifiers can be aliases for one or more
1858 other qualifiers (if more than one is given, OR is used).
1860 ZOOM uses named result sets if target supports it.
1862 Two new YAZ client commands: . (dot, which sources a script of YAZ
1863 client commands), and ! (to execute shell command.). Implemented
1866 Working on Debian packages.
1868 --- 1.8.3 2001/11/19
1870 YAZ client enables named result sets only if target supports it.
1872 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1874 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1875 with key="host" to get same result.
1877 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1878 Function Z3950_resultset_record(s) returns references to records
1879 "owned" by resultset. To become owner use Z3950_record_clone.
1881 Function z_ext_record handles Extended Services. Thanks to
1884 --- 1.8.2 2001/11/12
1886 CCL Parser fix: ignore token comma when dealing with and-lists.
1888 Documentation updates for COMSTACK.
1890 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1891 Changed prototype Z3950_records. For some functions, int parameters
1892 were changed to size_t.
1894 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1897 New MARC decode/display function, marc_display_exl, which properly rejects
1898 non-ISO2709 records. YAZ client uses it.
1900 --- 1.8.1 2001/10/29
1902 Fix bug: local attribute set wasn't set correctly in PQF strings.
1906 * Old Z39.50 codecs no longer supported.
1908 Added ZOOM C binding. See http://zoom.z3950.org/
1910 Renamed states for COMSTACKs to avoid confusion with events.
1912 Implemented cs_look and proper cs_rcvconnect.
1914 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1916 Configure detects POSIX threads on OpenBSD.
1918 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1919 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1921 When error is returned from present handler, non-surrogate diagnostic
1922 is returned in present response (and fetch handler is no longer called).
1924 * Minor adjustments to pquery parser (PQF). Token characters may be
1925 escaped by using backslash (C-style).
1927 PQF parser allows string attribute values to be specified. For @attr,
1928 non-numeric characters after the equal-sign are treated as strings
1929 (e.g. @attr 9=title).
1931 CCL trunction character may be defined (@truncation in file)
1933 * function zget_ExtendedServicesRequest sets waitAction to
1934 waitIfPossible (was wait).
1936 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1939 CCL operator names may be set in field definition files (CCL_bibset).
1940 See ccl/bib1 for an example.
1942 Fixes in ASN.1 compiler for C++ compatibility.
1944 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1945 and "op_or" to avoid conflict with C++.
1947 Fixed problem with GNU readline detection on Redhat 7.0.
1949 Added step-size for Scan backend handler.
1951 Fixed bug that made the frontend server crash when no attribute
1952 set was specified for scan.
1954 Front-end server automatically switches to original working directory
1955 when installed as an NT service. Previously -w had to be specified to
1958 Added extended attributes for retrieval module (data1), so that data1
1959 records carry d1_readXML/SGML attributes. d1_read also supports
1960 null-data rules ( <tag/>)
1962 On UNIX when POSIX threads are available, a separate library libyazthread
1963 is created. Programmers should link with that library and the yaz library
1964 when using threads. The reason for the split was that some applications
1965 on Linux, such as Apache, doesn't work well when using shared objects that
1968 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1969 (or any frontend server) in SSL mode by specifying ssl: followed by
1970 address. Only tested on UNIX.
1972 Added feature for CCL module. Virtual structure s=al or s=ol generates
1973 and-list and or-list respectively instead of phrase search.
1977 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1978 log_mask_str. This was done to avoid name conflicts with other libraries
1979 (such as other PHP extensions).
1981 Added raw OID member for preferred record syntax (request_format_raw)
1982 and returned record syntax (output_format_raw) for backend fetch method.
1984 Config file yaz-config now accepts options so that it returns specific
1985 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1987 Shared library support for UNIX using GNU libtool.
1989 * Modified backend interface. Request/Response struct's replaced by
1990 one read/write C struct. For example bend_fetchrequest and
1991 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1992 Every handler - even search has to be registered in bend_init
1993 handler. This means that the YAZ library no longer refers to
1994 external functions and it makes it possible to make the whole
1995 thing a single DLL/SO.
1997 Added Segment handler for backend server.
1999 Added Zmbol/Zebra administrative functions to YAZ client.
2001 Threaded frontend server on UNIX (when POSIX Threads are available).
2002 Starting the server with option -T enables multi-threading.
2006 Added configure option --enable-comp/disable-comp to control use
2007 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2008 located in sub directory asn.
2010 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2011 in ${exec_prefix}/bin along with the other programs yaz-client and
2014 GNU automake used to maintain makefiles.
2016 Added several OID's.
2018 Changed retrieval module so that we can load records with no abstract
2019 syntax defined. Tagpaths in these records are fully composed of string
2022 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2026 On UNIX, the generated makefile now supports a proper 'make install'.
2027 The prefix can be set via GNU configure to set the install location
2028 (default is /usr/local).
2030 * YAZ programs client and ztest were renamed to yaz-client and
2031 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2032 locations, such as /usr/bin,/usr/local/bin,etc.
2034 * YAZ Header files were moved from include to include/yaz. YAZ Header
2035 files are referred to as include <yaz/log.h> rather than <log.h>.
2036 The YAZ include path (-I ..) is therefore the same as before. Programmers
2037 should update their #include statements or use -Ipath/include/yaz
2038 instead. The main motivation for doing this change is that YAZ header files
2039 can be installed in "standard" locations /usr/include,/usr/local/include
2040 without introducing conflicts, since ALL YAZ header files are stored
2041 in subdirectory yaz (under /usr/include for example).
2043 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2044 rather than project/workspace files. We switched because project files
2045 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2048 Changed name of logging function, logf, to yaz_log, to prevent name
2049 clash with some math-log functions. The YAZ header log.h defines logf
2050 to yaz_log (#define) so there should be no incompatibilities by this
2053 Added bend_start/bend_stop handlers for server. These handler are
2054 called on start/stop of server. For windows they are called whenever
2055 a service is started/stopped.
2057 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2058 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2059 in util/yc.tcl. The auto-generated C code structures are, in a few
2060 cases, incompatible with the old decoders. There are differences in the
2061 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2062 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2063 The preprocessor variable ASN_COMPILED is defined when the compiled
2064 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2065 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2066 wish to use the old encoders/decoders you can specify --disable-yc
2069 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2070 version so that it supports both new - and old version of DB Update
2072 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2073 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2074 change. The name parameter can be set to 0 in which no name is specified
2075 for the construction. The macros odr_implicit and odr_explicit sets name
2076 parameter to zero for the construction involved. New macros
2077 odr_implicit_tag and odr_explicit_tag are similar to the others,
2078 except that a name parameter is added. For programmers' that don't use
2079 ODR they probably only need to change the call to z_APDU and z_External.
2081 Added access control facility by interfacing the TCP wrapper library.
2082 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2083 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2084 name of the daemon and enables the access control as specified in
2085 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2087 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2088 den Dool <H.M.vdnDool@kub.nl>.
2090 Added reference ID parameter to most functions in server API - refer
2091 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2093 Changed name of ccl library to libccl.a (was ccl.a).
2095 Fixed bug in decoder for Explain (Category TargetInfo).
2097 Added support for GNU readline in client. Thanks to Jacob Poulsen
2098 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2100 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2101 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2102 IMPLEMENTATION! This change was made to the development version before
2103 the ZIG decided to retract the amendment. If any users MUST be
2104 compatible with the original Update definition, PLEASE CONTACT US, and
2105 we will include a separate definition corresponding to the old Update
2106 ES. Note that because of the change to the ASN.1 of the
2107 TaskPackageRecordStructure we cannot define a single structure that
2108 will support both versions.
2110 * Added const modifier to buffer parameter for some ODR/BER encoding
2111 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2112 completeWAIS, odr_dumpBER.
2114 Fixed bug in client.c which caused a crash when a scanResponse didn't
2115 contain positionOfTerm.
2117 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2118 * will cause an error in a client if a non-YAZ target sends both a
2119 * list of Scan entries and non-surrogate diagnostics.
2121 Retrieval module enhancements. Tag sets may be typed in the reference
2122 to it. From the .abs-file the "tagset" directive takes a third optional
2123 integer type for the tag set referenced. From a .tag-file the "include"
2124 directive takes a third optional type as well. The old "type" directive
2125 in the tag set itself is still recognized but acts as the default type
2128 Backend interface change. Individual Scan terms returned from bend_scan
2129 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2130 in include/backend.h.
2132 Retrieval module enhancements. Multiple tag sets and attribute sets may
2133 be specified in abstract syntax specs. Revised the error/warning for
2134 logging messages reported by the retrieval module when reading the
2137 Object Identifier system (oid_..) changed. The API is backwards
2138 compatible but the oid-routines now allocates new OID's when needed.
2139 Raw OID's may be specified in oid_getvalbyname.
2141 YAZ now uses GNU configure to generate Makefile(s).
2143 * Minor changes in some of the member names of DeleteResultSetRequest and
2144 DeleteResultSetResponse. See include/proto.h.
2146 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2147 and added member 'languages' in TargetInfo (which was missing).
2149 Changed the way attribute sets are handled in the retrieval
2150 module. These are now cached, just like the abstract syntaxes
2153 Changed YAZ so that it links with compiled ASN.1.
2155 Added Explain-schema definitions and mapping routines. The following
2156 Explain categories have been implemented: AttributeDetails,
2157 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2159 Fixed minor bug in Windows version of Server Library.
2161 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2163 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2165 Added EXTERNAL: UNIverse Resource Report (non-standard).
2167 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2168 ENUMERATED and SET OF.
2170 * Added 'const' to some of the char pointer arguments for the
2171 functions, data1_read_node, data1_getelementbytagname,
2172 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2175 Fixed bug in data1_insert_taggeddata - the last_child member of
2176 parent wasn't initialised.
2178 * Changed data1_read_record and data1_read_node so that the supplied
2179 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2180 doesn't refer to any parts of the "SGML"-buffer.
2182 Fixed bug in server library (Windows version of statserv_remove).
2184 * Changed code so that it compiles as C++. The type definition
2185 of Odr_fun which is a member of Odr_arm was changed. The result is,
2186 that an explicit typecast is needed for the fun pointer when
2187 using Odr_arm - as in:
2188 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2190 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2192 Implemented the new structured date and time definition as approved
2193 by the ZIG. Added schemaId element to the specificTag in Espec-1
2194 (also approved at the last ZIG). Thanks to RVDM.
2196 Added some Object identifiers (RVDM).
2198 Changed the Update Extended Service (RVDM).
2200 Added command "refid" to client which specifies referenceId for
2201 the following requests.
2203 Implemented extended service handling for server. See ztest.c
2204 for an example as well as backend.h. New handlers are registerd
2205 in the Init handler.
2207 * Changed interface for sort in server.
2209 Added new members to statserv_options_block. It allows a server
2210 to read options from another source than just the command line. Thanks
2211 to Charles Woodfield.
2213 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2214 renamed to zboolean. Some C++ compilers complained about the name.
2216 Minor changes to gils.abs. Added index 's' (sort) on title
2217 and date/time-last-modified.
2219 --- 1.4pl2 1998/1/30
2221 Fixed bug in server library regarding inetd mode (-i). This bug
2222 was introduced by release 1.4.
2224 --- 1.4pl1 1998/1/29
2226 Added sort facility in client and backend server interface.
2228 Fixed problem with dependencies in Makefile(s).
2230 Fixed bugs for encoders/decoders of extended services and
2233 Implemented sub-tree feature for schemas. Sub-trees are
2234 referenced in *.abs-files. See explain.abs for an example
2235 of the use of this feature.
2237 Modified bib1.att; local attributes for ANY didn't include
2238 ANY itself (only affects use of the retrieval module).
2240 Fixed bug in plain SGML reader in function data1_read_node:
2241 tags with prefix "var" was incorrectly interpreted as variants.
2243 Added feature "sub-schemas" to enable references to - and definitions
2244 of - group of elements.
2246 * Removed member parent from type data1_element (in data1.h).
2248 Implemented function odr_nullval() that returns the value of
2251 * Removed member num_children from data1_node (in data1.h).
2253 Made NT service interface part of the server library. The
2254 function statserv_main uses the NT service when required and
2255 calls the statserv_start / statserv_close routines.
2257 Routine zget_SearchRequest and zget_PresentRequest fills
2258 resultSetName/Id member with "default" instead of "Default".
2260 Fixed memory leak in server. Request queue member wasn't freed.
2262 Fixed nmem_exit so that memory is freed.
2266 Revised the CCL parser utility to be thread safe.
2268 Added function, oid_ent_to_oid, to replace the function
2269 oid_getoidbyent, which is not thread safe.
2271 * Added nmem_init and nmem_exit to initialize and release
2272 NMEM resources. Function nmem_init should be called once in the
2273 initial thread before NMEM/ODR is used. statserv.c and client.c
2274 have been changed accordingly. The change was necessary to make
2275 NMEM thread safe. The NMEM memory pool is shared amongst threads
2276 in a process. Unix-based applications will still work fine without
2279 Added NT Services interface for the the Z39.50 (statserv) Server.
2280 Refer to the ztest.c source on the usage.
2282 Windows 95/NT port using MSVC5.0. Project files are included in the
2285 * Defined new 'global' handle for the retrieval (data1) system. The
2286 new handled, data1_handle, describes the state of the data1 system.
2287 This handle is passed as first argument to virtually all
2288 data1 related routines. The functions data1_create and data1_destroy
2289 creates and destroys a data1 handle respectively.
2291 Added ODR encode stream member to all backend request structures
2292 init, search, scan etc. This stream should be used to allocate all
2293 memory used for the response when thread safe operation is needed.
2295 Changed the comstack utility, cs_addstr, to be thread safe. The
2296 returned hostname string returned by the function is now part the
2299 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2300 function. The cs_straddr takes a COMSTACK handle as argument, so this
2301 function must be used after cs_create and before bind/connect.
2302 This function is thread safe.
2304 Moved test server to 'ztest' directory - generic server code still
2305 in 'server' directory.
2307 Made prefix query (pquery.c) utility thread safe.
2309 Added new function modifier YAZ_EXPORT to 'export' public DLL
2310 functions when using windows (see include/yconfig.h).
2312 Added definitions to the OID database (util/oid.c) (RVDM).
2314 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2316 Added call to ccl_rpn_delete in client program.
2318 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2319 release of RPN structure.
2321 Added support for C++, headers uses extern "C" for public definitions.
2322 With input from RVDM.
2324 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2325 Thanks to Ronald van der Meer (RVDM).
2327 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2329 Added support for private extensions to the OID database
2330 (oid_setprivateoids()). Thanks to RVDM.
2332 Added optional, physical ANY (key replication)
2334 Fixed null-reference problem in GRS-1 output filter.
2336 Proximity operator added to Prefix Query Format (PQF).
2338 In test client command "base" accepts multiple databases.
2340 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2344 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2346 Smallish bug-fixes in the new encoders/decoders (explain).
2348 Bug fixed in DeleteRequest.
2350 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2352 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2354 Added SOIF syntax (using private OID for now) to retrieval module and client.
2356 Added Update extended service.
2358 Added SearchResult-1 additional info structure.
2360 Added optional CCL (ISO8777) interpreter as separate module. Available
2363 --- 1.2 1996/6/10 (1st anniversary release)
2365 Added Summary record syntax. Lightly tested.
2367 Added OPAC record syntax. Untested.
2369 Added ResourceReport service encoders/decoders. Untested.
2371 Fixed bug in z_Unit - wrong tagging on unitSystem.
2373 Fixed bug in the DiagRecs decoder.
2375 Added options for max PDU size and session timeout to frontend-server.
2377 Added documentation of query-language parsers and other supporting utilities.
2379 [frontend-server] Added Attribute set to the bend_scanrequest API.
2381 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2382 surrogate diagnostics were generated.
2384 [retrieval] Allow multiple local values for attribute.
2386 [retrieval] Allow multiple attributes per element in .abs files. index type.
2388 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2390 --- 1.1pl2 1996/4/10
2392 Minor changes, mostly specific to Zebra's requirements (retrieval)
2396 Repaired bug in frontend server when running multiple listening
2397 endpoints in dynamic mode.
2399 z_External() now won't break if a known, ASN.1 value comes encapsulated
2400 in an octet-string. The value will pass through unmodified in an Odr_oct.
2402 Added a bit of code to the demo client to decode & display
2403 ASN.1-structured records represented in the octet-aligned branch of
2404 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2406 Added z_ext_getentbyref() to the ASN module. Doc updated.
2408 * Completed the SCAN definition in the ASN module. This may break SCAN
2409 code based on older YAZ-versions at compile-time. The fix is easy -
2412 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2413 under the SCAN definition. Remember to initialize this, server-people.
2415 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2416 that this does not extend to ODR and ASN.
2418 Comstack allows insertion of established socket (primarily for
2419 inetd-operation of servers). Doc updated.
2421 Front-end server can now start from the inetd in TCP mode. Doc
2424 --- 1.0pl4 1996/1/24
2428 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2429 the rank and record number.
2431 Adjustments to the frontend server.
2433 Fixed diagnostic BER dumper. It ignored the file argument.
2437 Various changes to retrieval module.
2439 Changed the union discriminators of the protocol files from enums to
2440 ints paired with #defines.
2442 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2445 *Changed operator in the RPN structure to 'roperator', again to avoid a
2448 Fixed problems in Explain decoders/encoders.
2450 --- 1.0pl2 1995/12/6
2452 Memory bug in log module fixed.
2454 --- 1.0pl1 1995/12/5
2456 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2458 Bug in Explain DatabaseInfo module fixed.
2460 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2464 The shift to v1.0 signals that we now consider the *core* functionality
2465 of YAZ reasonably stable (the core being more or less equivalent to
2466 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2467 tested (Explain not at all - though that will happen soonish).
2469 Minor changes to code to support Windows port.
2471 Various minor changes after we're getting to use GRS-1 & co. more.
2473 Added Espec-1 format.
2475 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2476 of the protocol and it cannot be selected when encoding (maps into 'string'
2477 when decoding). Needed to talk to some servers.
2479 Demo client can request simple element set names.
2481 Added Diagnostic Format encoders/decoders.
2483 Added simple Close handling to frontend server (no hooks for resource
2484 reporting yet), and demonstration client.
2486 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2488 --- 1.0b3 1995/08/24
2490 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2491 handled incorrectly when records were requested in the searchResponse. This
2492 will only affect you if you use the frontend-server.
2494 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2495 Test-client will ask for and print GRS1. Ztest will return dummy records
2498 Added Explain encoders/decoders to the service-level API. Untested.
2500 Added Extended Services: Item Order encoders and decoders to the Service-
2501 level API. Untested. We could use a recent copy of the pertinent bits
2502 of the ILL protocol to add those bits.
2504 Added diagnostic format 1 encoders/decoders to the service-level API.
2507 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2508 odr_cons.c, which causes a more correct output.
2510 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2511 was always set to 0 when no records were requested in the searchRequest.
2513 * Added better external-handling. This shouldn't harm old code that
2514 *encodes* externals. It can break code that looks for a
2515 'single-ASN1-type' representation, since those types that are known
2516 are now decoded immediately. Look at the SUTRS sample code in
2517 seshigh.c and client.c. Documentation updated.
2519 Handling of structured records in bend_fetchresponse. Length -1 marks
2520 structured record, type is deduced from format field.
2522 --- 1.0b2 1995/06/27
2523 Fairly quick maintenance release to add SUTRS support.
2525 Fixed handling of SUTRS records in the demonstration client.
2527 * Added format field to the bend_fetchrequest and bend_fetchresponce
2528 structures of the backend API (frontend server). When the record is
2529 returned, the value of the format field is mapped to an OID. The
2530 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2531 of the record. The special value VAL_NONE in the bend_request means
2532 that no specific format was requested by the client. Documentation
2533 updated accordingly. Test server (ztest) will return a fixed dummy
2534 SUTRS record if your client requests SUTRS.
2536 Documentation updated accordingly.
2538 You can now set external libraries and RANLIB support in the top-level
2542 First public release.
