3 List supported encodings in man page for yaz-iconv.
5 Fixed missing SSL libs for --libs output
7 Re-established OID record syntax application-xml. Nobody should use it
8 but we don't want to change soname because of this symbol being absent.
12 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
14 Added member named_result_sets for init handler struct for the GFS. This
15 allows a server to disable named result sets.
17 Removed OID record syntax application-xml.
19 Added support for rule-based transliterator for ICU wrapper of YAZ.
21 Fixed bug #1902: yaz-icu XML output.
23 Make YAZ checks Emacs friendly.
25 BITSTRING value shows value. Bug #2346.
27 ISO2709 decoding: skip control characters from indicator data.
29 Omit sort key by default in yaz-icu's output.
31 Allow combined single char options (again) for YAZ' options function.
33 Utility yaz-marcdump got option to display YAZ version (-V).
35 Allow YAZ to use ICU 3.4.
37 Added new ICU test case which illustrates removal of diacritics.
41 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
45 For configure, using option --without-xml2 also disables Libxslt/Libexslt
48 Fixed bug #2352: yaz-marcdump crashes for certain record.
50 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
52 Added support for Danmarc2 to UTF-8 conversion.
54 Added support for ISO5426 to UTF-8 conversion.
56 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
57 implementation version.
59 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
63 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
64 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
66 ZOOM C now interprets databaseName option for ZOOM connection as path
69 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
71 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
73 Dummy Libxml2 types no longer defined in headers of YAZ'.
75 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
80 Various ODR chapter fixes.
82 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
84 Added missing source for Windows compilation, mutex.c.
86 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
88 For SRU connections in ZOOM all records up to "count" are now fetched.
90 Fixed crash in generic frontend server (and yaz-ztest) which occurred
91 in Windows due to bad error handling for Libxml2.
93 Added facility for sending arbitrary records (ASN.1 any) using
94 ZOOM C's Extended service update. Patch by Sam Reynolds.
96 New options for ZOOM C's connection, logapdu which makes ZOOM log
101 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
103 --- 3.0.32 2008/06/12
105 Fixed memory violation that could occur when decoding UTF-8. This bug
106 was only present in 3.0.30 of YAZ.
108 --- 3.0.30 2008/06/06
110 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
111 GNU TLS is used by default (if found).
113 yaz-ztest returns OPAC records if a client asks for OPAC.
115 Improved speed of MARC-8 encoding.
117 Added support for lossy and loss-less MARC-8 encoding.
119 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
121 Added new Windows Service wrapper (sc).
123 yaz-client's itemorder command may now send a file.
125 Fixed yaz-marcdump to allow the use of NS prefix for record element.
127 Added new function yaz_log_xml_errors.
129 Allow (but warn) unknown XML attributes in MARCXML parsing.
131 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
133 The UTF-8 to MARC-8 conversion now uses a different set of characters
134 for Greek symbols. Bug #2120.
136 --- 3.0.26 2008/02/21
138 Added yaz_daemon (daemon.h).
140 Fixed bug #2068: pkg-config trouble
142 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
144 --- 3.0.24 2008/01/28
146 Document --with-xml2 option.
148 Added OPAC XML XSD (etc/opacxml.xsd).
150 Allow glob mask for name attribute in retrieval element for the
151 generic frontend server's retrieval facility.
153 Changed yaz_poll_poll to return yaz_poll_except for all returned events
154 except POLLIN/POLLOUT.
156 Fixed error handling in cs_listen. Bug #2037.
158 --- 3.0.22 2008/01/20
160 Fixed version in yaz/yaz-version.h.
162 Fixed bug #2027: Crash when closing connection.
164 Changed configure so that ICU support is only enabled if only ICU
165 and Libxml2 is available (because the ICU chain is XML based).
167 --- 3.0.20 2008/01/15
169 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
170 is built. Only this DLL depends on the ICU runtime.
172 yaz-ziffy is no longer part of YAZ. It is distributed separately by
173 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
175 Changed license of CCL module to 'Revised BSD'. After consultation with
176 remaining members of the original EUROPAGATE consortium, we are re-issuing
177 the CCL module without a separate license. The software was developed by
178 Index Data as part of a research project. The special license was included
179 to help feed usage information back to the project consortium to support
180 project evaluation. At this time, the project consortium has long-since
181 disbanded, and the majority of the original principals have retired. At the
182 same time, we have significantly modified the software during the following
183 years, to the point where very practically no original code remains. To
184 simplify re-use of the software, we have contacted those members of the
185 consortium who could be reached, and agreed to re-issue the module as a
186 proper part of the YAZ package.
188 Tcl scripts uses /usr/bin/tclsh as preferred shell.
190 CQL closer to being version 1.2 compliant. CQL also allows free-form
191 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
194 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
195 bug could make Extended services handling crash in the ZOOM layer. This
196 bug was only present in YAZ 3.0.18.
198 --- 3.0.18 2007/12/19
200 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
203 yaz-marcdump reads and writes collection wrapped records.
205 Handle OPAC for record conversion module.
207 Fixes for ICU wrapper.
209 Allow ICU libs to be controlled with --with-icu .
211 --- 3.0.16 2007/11/12
213 Added yaz_poll which is a wrapper for select/poll. When poll is available
214 and non-buggy, it is used, by yaz_poll . This allows more than 1024
215 sockets to be in use.
217 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
218 functionality through an XML based configuration (ICU chain). This system
219 is useful for search facilities such as Pazpar2 and Zebra that needs to
220 perform tokenization of indexed material. The ICU code in a separate
221 library libyaz3_icu.a.
223 Added HTTP tunnel facility for COMSTACK, bug #1752.
224 This is a facility that allows a Web proxy, such as squid, to tunnel
225 Z39.50 traffic. This facility is "transparent" to must applications
226 using YAZ. It's enabled by using pseudo transport connect: followed by
227 the proxy address, followed by command, then follwed by he regular
228 "virtual" addresss. For example,
229 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
231 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
233 --- 3.0.14 2007/09/21
235 Fixed bad memory reference in ZOOM_record - cuased by member not being
236 initialized. This was a problem only in YAZ 3.0.12.
238 Fixed bug in conversion from MARC to XML: Non-XML characters in control
239 fields were not removed.
241 Changed the way C code is generated from codetables.xml. Made a MARC-8
242 conversion trie for each characterSet section rather than codeTable.
243 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
244 of codetables.xml from Larry Dixson, LOC. Bug #1464.
246 --- 3.0.12 2007/09/12
248 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
249 from ZOOM_record_error).
251 ZOOM C function ZOOM_record_get returns record schema for type="schema".
253 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
255 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
257 Better SRW-to-Bib-1 diagnostic mapping.
259 ZOOM C and yaz-client announces SRU version 1.2 by default.
261 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
264 Fixed in yaz_sru_decode to allow other version than 1.1.
266 --- 3.0.10 2007/08/22
268 Added support for SRU scan for ZOOM.
270 Added support for the use of the older versions or Extended Service
271 Update in ZOOM. To faciliate this, an option "updateVersion" may be
272 set to the version , 1=first, 2=second, 3=third. The third version is
273 what ZOOM C has used so far. And that, obviously, is the default.
275 Added support for CCL queries in Z39.50 queries sent to the GFS (and
276 therefore in Zebra and in SimpleServer-based applications). The new
277 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
278 qualifier file used to transform incoming CCL queries into Type-1 RPN,
279 which is passed into the back-end search callback function.
281 Added support for HTTP Basic authentication in clients: the SRU/W
282 codec encodes the username/password elements of the PDU structure
283 appropriately, and these may be set using the "user" and "password"
284 options in ZOOM-C applications (the same options that are used for
285 Z39.50 authentication).
289 Fixed bug #1208: SSL appears to be broken in ZOOM.
291 Fixed bug #1206: Libxml2 include path weirdness.
293 Added oid_name_to_dotstring.
295 Allow elementSetName to be specified for ZOOM C record update.
297 Allow waitAction to be specified for ZOOM C based for Extended Services.
299 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
300 syntax OID. Bug introduced in YAZ 3 series.
302 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
306 Fixed bug #1157: yaz-client does not read .yazclientrc from current
307 directory. yaz-client now reads commands from file given by option -f
308 if specified; then tries to read .yazclientrc in current directory.
309 Failing that, it reads .yazclientrc from user's home directory.
311 Added support for correlationInfo Note and ID for Record Update via
314 Added yaz-client command querycharset which specifies character set for
315 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
316 (termListAndStartPoint).
318 Charset ISO5428:1984 is an alias for ISO5428-1984.
320 Implemented a way to perform scan in a result set using Z39.50. This
321 is achieved by attaching the result set name in the characterInfo
322 (type InternationalString) of OtherInformation in the Scan Request PDU.
323 The result set is identified in the otherinformation by the new OID:
324 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
325 This allows for scan in result set and faceted search . Zebra did some
326 of this in the APT term using attribute type 8 and value being result
327 set. Using the OtherInformation approach for this is cleaner and easier
328 to work with in proxies and the like. This facility can be used in
329 yaz-client using new command setscan which takes a result set as first
330 argument, start position (APT) as second.
332 Changed decoding of SRU XML packed records to deal with servers that
333 have recordData with XML data with multiple root nodes. Also make
334 comparison for recordPacking case insensitive. Again, one server
335 returns "XML" where others return "xml".
337 For SRU responses allow Content-Type application/xml as well as text/xml.
341 Fixed bug in character set conversion of BER strings. Bug introduced
346 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
348 For OID class, use oid_class consistently.
350 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
353 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
354 character set for bibliographic information interchange". By Giannis Kosmas.
356 Added documentation on new OID API.
360 Changes to generic frontend server interface: added new member
361 'query_charset' for bend_initrequest structure. A backend init handler
362 should set this member to its native character set for query terms.
363 When defined, the frontend server logic will announce this character set
364 to a client if the negotiationModel bit is set by the client. All server
365 implementors are encouraged to specify this. If a backend server does not
366 specify this a warning is issued using yaz_log(YLOG_WARN,..).
368 Added CCL utility to remove terms (stop words) from resulting RPN
369 tree. This is handled by functions with prefix ccl_stop_words_ .
371 New ZOOM C option, "rpnCharset", which allows client-side conversion of
372 terms in RPN queries.
374 Clean-up the CCL API. Moved some internal structures from ccl.h to
375 private header cclp.h. Changed ccl_parser_create so that a Bibset must
376 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
377 This is replaced by ccl_parser_find_str which takes a string instead.
379 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
380 libyaz.la is the core of YAZ except the generic frontend server and
381 does not depend on POSIX threads anymore. libyaz_server.la is the
382 generic frontend server facilities and uses POSIX thread functionality
383 if available. The libyaz.la no longer depends on POSIX threads because
384 the number of global structures is limited. NMEM no longer re-uses blocks
385 between threads ; it simply free's memory immediately but allocates in
386 "large" chunks as usual. We don't expect any performance penalties
387 because of this. The yaz_log system is still using a global log_level so
388 caution must be taken when modifying it with yaz_log_init_.. +
389 yaz_log_mask_str. This, however, should not cause any trouble because
390 these functions are called during initialization of application code
391 anyway. `yaz-config --libs server` returns libs for server applications;
392 `yaz-config --libs` returns libs for non-server applications.
394 New OID database - with public definitions in oid_db.h. Removed old OID
395 database including the head oid.h and definitions such as enum oid_value
396 and struct oident. The new OID database uses the same string names as
397 before but the 'protocol' is gone. There are now only two representations
398 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
399 converts from string to OID; functions with prefix yaz_oid_to_string
400 converts the other way.
402 Change to emit_term() in CQL-to-PQF query translation: when a term has
403 the /regexp relation modifier, do not process it for leading and
404 trailing "^" and "*", which have quite different meanings in regular
407 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
408 write handlers no longer carries a 'last' parameter. This will make
409 yaz_iconv flush "less" characters. A flush is performed by call to
410 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
412 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
413 removed, because function yaz_query_to_wrbuf does the same.
415 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
416 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
418 Deprecated MARC utility functions removed.
420 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
423 Branch split: YAZ_2_1_55_branch
425 --- 2.1.54 2007/03/16
427 Fix to ZOOM-C so that transparent reconnection is properly handled on
428 connections that are in asynchronous mode.
430 Fixed compilation on OpenBSD 4.0.
432 Large strings in GRS-1 records are now properly displayed in yaz-client.
434 Added character conversion support for "advancegreek"; based on patch from
437 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
438 sequence is met. Before the error was not set so it would be unknown.
440 Adjust yaz-marcdump MARC reader so that it skips until record separator
443 --- 2.1.52 2007/03/07
445 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
446 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
447 fd_set structure used as a bitmask for the FDs to be selected on.
449 Using ACX_PTHREAD macro to check for POSIX threads.
451 Fixed have-vsnprintf check.
453 --- 2.1.50 2007/02/23
455 Fixes for configure on BSD. Bug #900.
457 Added snprintf/vsnprintf wrappers for systems that don't have
458 limits (heavens forbid).
460 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
461 created before all previous tasks were completed and removed from the
462 task queue, the new task could be removed by a mistake.
464 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
466 Implemented pass-through CQL-to-PQF conversions. Bug #861.
468 Fixed bug #832: Problem with MARC/charset in yaz-client.
470 Fixed bug #668: save command line history for yaz-client.
472 Fixed bug #830: pkg-config support.
474 --- 2.1.48 2007/01/23
476 Extended ZOOM result set options with two options that may be read by
477 a client: resultSetStatus and presentStatus with values as specified for
479 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
481 Fixed bug #827: Using SSL fails on Debian etch.
483 Fixed bug #826: Weird looking chars for set of MARC records.
485 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
486 that is treated as an ItemOrder with itemRequest being an XML document
487 external. The value of "doc" is the content.
489 Extended the GFS search facility. New member of bend_search_rr
490 'estimated_hit_count' signals that hits is known to be an estmate
491 (higher or lower than real hit count). New member 'partial_resultset'
492 signals that the search was partial (hit count is lower or equal than
493 real hit count). For Z39.50, the information is stored in resultSetStatus
494 member of SearchResponse APDU. For SRU, the information is signalled
495 via SRU diagnostic 59: "Result set created with valid partial results
498 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
500 --- 2.1.46 2007/01/13
502 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
504 Added ZOOM_connection_peek_event.
506 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
507 the following new functions:
508 ZOOM_event_nonblock, ZOOM_connection_process,
509 ZOOM_connection_get_{socket,mask,timeout},
510 ZOOM_connection_fire_event_{timeout,socket}.
511 The existing blocking event handler, ZOOM_event, is a wrapper for the
512 + blocking ZOOM_event_sys_{poll,select}.
514 Implemented function ccl_xml_config which parses XML version of CCL
515 configuration (bug #798).
517 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
519 Added timings utility (yaz/timing.h)
521 --- 2.1.44 2007/01/03
523 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
526 Fixed bug #779: Rotation of apdu.log fails.
528 Fixed for character set conversions:
529 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
530 Honor G1 set in MARC-8 decoding.
532 --- 2.1.42 2006/12/17
534 Fixed bug #775: char conversion does not handle Alternative UTF-8
537 Implemented function yaz_marc_read_line which parses MARC line format
538 records. There is a wealth of formats out there. So far, this function
539 reads line records produced by yaz_marc_write_line.
541 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
542 more generic and easier to remember(!) options: -i format and -o format
543 which specifies input format and output format respectively - where
544 format is one of "marc", "marcxml", "line", "marcxchange".
546 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
547 does not print anything except warnings for records.
549 For yaz-marcdump, added support for MARC split into files (-s) with a given
552 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
553 spec, at http://www.loc.gov/standards/sru/record-update/
554 This has changed the binary layout of the following structs:
555 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
556 bend_update_rr . Patch by Ko van der Sloot.
558 Added GFS utility function bend_assoc_is_alive which returns 1 if
559 association is still alive (client is connected); 0 otherwise (client
560 closed connection). This allows busy servers to stop working for
563 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
564 been a separate piece of software. This version of ziffy has been modified
565 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
567 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
569 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
570 Client code may now interrogate options such as "init_opt_sort" to
571 find out whether the server claims to support various options.
573 --- 2.1.40 2006/11/27
575 Added utilities yaz_{set,get}_esn to set/get element set name from
578 Removed the build of libyazthread.la. The libyaz.so is the threaded version
579 of YAZ and has been so since YAZ 2.1.10.
581 Implemented ZOOM_record_error which returns error information for
582 record (surrogate diagnostic).
584 --- 2.1.38 2006/10/31
586 Updates for SRU Update by Ko van der Sloot:
587 1. Changed name from "operation" to "action"
588 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
589 versions in the code, marked as 'backward compatible'.
590 3. Added diagnostics for SRU Update.
592 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
594 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
596 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
598 For GFS, fixed problem with SRU diagnostic 'First record position out of
599 range' being issued for 0 hits.
601 zoomtst10 part of Windows Build.
603 --- 2.1.36 2006/10/13
605 Implemented yaz_filepath_comp which splits a path into file path
606 components (required by Zebra 2.0.3+).
608 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
609 BSD inspired license until now so this should not have any real impact on
610 anybody. See http://www.opensource.org/licenses/bsd-license.php
612 Fixed bug #687: Missing log lines.
614 Fixed bug #678: CQL to PQF translation does not preserve double-quote
617 Fixed bug #689: SRU diagnostics to be added.
619 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
620 whether a connection is idle (no more work do do).
622 --- 2.1.34 2006/10/04
624 Change type of optval from long to int for invocation of setsockopt with
625 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
627 Added support for specifying the max log file size for the Generic
628 Frontend Server. The size is given with option -r.
630 --- 2.1.32 2006/09/21
632 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
634 --- 2.1.30 2006/09/17
636 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
639 Fixed bug in Generic Frontend Server that could cause a server to stop
640 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
642 For the generic frontend server, the maximum record size is used as maximum
643 size of incoming packages (SRU + Z39.50). The value until was previously
644 only used in Z39.50 Init negotiation and, later, in a session controlled
645 sizes of records returned. This is controlled using -k option. It can be
646 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
648 --- 2.1.28 2006/09/04
650 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
653 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
655 New option for yaz-marcdump -lpos=value which allows setting a portion
656 of MARC header to a certain value.
658 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
660 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
661 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
663 --- 2.1.26 2006/08/15
665 Fixed problem with SRU mode type (soap, get, post) for yaz-client
668 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
670 --- 2.1.24 2006/08/08
672 Fixed MARC ISO2709 encoding routines to deal with character set
675 Minor changes to GFS logging. Database included in search request log
678 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
679 cached/multiple records.
681 Shared libraries are built by default on Unix+configure.
683 Changed cql2pqf transformation to use a different evaluation order. The
684 new order is: always, relation, structure, position, truncation, index
685 and relationModifier. Old order was: always, relation, relationModifier,
686 structure, index, position, truncation. Note that the the latter ones
687 override former ones for identical attributes.. The new scheme means that
688 it is possible to override any existing attribute with a relationModifier.
689 And also that it is possible to override everything for the index rule
690 (except the ones listed in relationModifier). No order is perfect but this
691 one, we believe, covers more real cases.. The "always" should have been
692 called "default", since the attributes there can be overridden with all
695 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
696 compilation phase, but also for yaz-config --cflags output. This allows
697 us to have public headers with Libxml2 stuff in them . It should also,
698 eventually, make Libxml2 checks redundant in packages using YAZ, such
701 --- 2.1.22 2006/06/15
703 Changed SRU update structure bend_update_rr so that SRU diagnostics are
704 stored in uri, message and details.. Previously diagnostics were stored
705 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
706 compatibility.. but he's probably the only one affected, so.
708 Added support for CCL, compiled on the client side, in ZOOM-C. This
709 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
710 input; the resulting query objects can be used for for searching with
711 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
713 YAZ' configure searches for OpenSSL by default.
715 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
716 SL_CTX_use_certificate_file. See
717 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
718 for more info. Thanks to Ko van der Sloot.
720 --- 2.1.20 2006/06/02
722 Bug #600: SRU GET, POST support for yaz-client. Introduced
723 command 'sru' which selects method SOAP/GET/POST.
725 Allow missingValueAction to be specified for the sortspec string -
726 function yaz_sort_spec. By default, the missing value action is null.
727 Use ! to specify "abort". Use = followed by stringvalue to specify default
730 Ensured that Present-handler (if defined) is called in GFS before any call to
731 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
732 searchRetrieve requests.
734 Documentation for YAZ is now based on the Docbook XML/XSLT using
735 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
736 is no longer depending on jade/openjade or docbook-to-man scripts.
737 PDF is no longer part of the distribution - but can optionally be
738 made using DSSSL/jadetex or FOP.
740 Added retrieval handling support in Generic Frontend Server to support
741 conversion between MARC/XML as well as XSLTtransforms. See
742 etc/yazgfs.xml for an example.
744 Added Authentication support to Generic Frontend Server in SRU
745 mode. Authentication using HTTP Basic is supported, as is the use
746 of 'x-username' and 'x-password' parameters in the request itself.
748 Added support for a new character set MARC8s identical to MARC8 except
749 that it converts combined characters to single Unicode characters in the
750 Latin-1 range (when possible).
752 --- 2.1.18 2006/04/24
754 ASN.1 compiler 0.4: generates brief Doxygen file header for
755 generated .h/.c files.
757 Utility yaz_iconv now supports conversion to MARC-8.
759 New facilities for the MARC module. The reading - and writing of
760 content are separate methods for the yaz_marc_t handle. The following
761 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
762 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
763 format). Write functions have prefix yaz_marc_write_.. The existing
764 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
765 available. Removed support for OAI-MARC and simplexml (not the
766 simplexml from PHP5).
768 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
769 to be returned for this connection.
771 --- 2.1.16 2006/03/31
773 Allow multiple languages and charsets to be specified with
774 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
775 negcharset iso-8859-1,utf-8
777 Translation of proximity nodes from CQL into PQF now works.
779 Moved to automake 1.8, 1.9.
781 Added function yaz_log_set_handler which allows a log handler to be
782 installed. This handler will be called for all log messages. Output
783 to file is also produced; but that can be disabled by passing NULL
784 fname to yaz_log_init_file.
786 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
788 For SRW (including GFS), accept application/soap+xml as content-type
791 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
792 produces NO stylesheet reference even if a default stylesheet is specified
795 --- 2.1.14 2006/03/14
797 Updated Windows package to include yazd.dll + yazd.lib for the
798 Development component.
800 If the environment variable YAZ_LOG is set, then it is used as a
801 string indicating the default level of logging to use if not
802 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
803 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
804 used as before. So, for example, to omit warnings from YAZ logging,
807 cql_transform() now map structure and other attributes before indexes,
808 so that index-specific structures and other attributes can override
809 defaults. So now a combination of mapping specifications such as:
811 index.dc.date = 1=date-modified 4=5
812 does the right thing.
814 cql_transform() now also respects the "always" mapping specification,
815 which establishes an initial set of attributes to be used for all
816 terms except where overridden by more specific attributes associated
817 with the index, relation or modifier.
819 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
820 which mode to use; one of "post", "get" or "soap" (SRW, default).
822 Fixes for yaz_iconv routines: changed trie-based character set conversions
823 to use only non-negative values for bit fields due to Sun's C compiler not
824 supporting negative values.
826 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
827 sequences where not read correctly. Fix by Rustam Usmanov.
829 Updated win/makefile to use options, settings which makes things
830 compile with VS C 2005.
832 --- 2.1.12 2006/02/01
834 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
836 In ZOOM socket code, use select instead of poll on MacOSX.
838 ZOOM-C now support client-side compilation of CQL into RPN that is
839 sent to the server, enabling CQL to be used against all Z39.50
840 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
841 ZOOM_query object, and submit it using ZOOM_connection_search().
842 The CQL-to-RPN translation uses a configuration file, the name of
843 which must be specified in the Connection's "cqlfile" option.
845 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
846 function, which takes as its start-term parameter a ZOOM_query object
847 (which may have had either CQL or RPN set into it).
850 --- 2.1.10 2005/11/29
852 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
853 GFS to support this as well. Backend handler, bend_srw_update, does the
854 update work. Code contributed by Ko van der Sloot.
856 Allow retrieval of Search Result-1 information in ZOOM by the use of
857 options that are attached to a result set. ZOOM documentation updated
860 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
861 UTF-8 conversion. Patch by Raj Patel.
863 Added option -m to GFS to control formatting of timestamps in log file.
865 Added 'exit' as synonym for 'quit' in yaz-client
867 Added support for specifying SRW resultSetId + resultSetIdleTime in a
868 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
869 for the new members. Patch by Ko van der Sloot.
871 Added support for SRU POST. It is supported for content-type
872 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
874 Do not build the separate Multi-threaded (MT) library libyazthread.la.
875 Instead make the library libyaz.la multi-threaded. Threading as a whole
876 can still be disabled by configure option --disable-threads. Previosly,
877 with older GLIBCs there were problems with MT libs under Apache. This
878 has now been fixed a long time ago.
880 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
883 CQL module modified to be case insensitive for relations/indexes/operations.
885 Fixed bug in CQL transform code: incorrect value relationModifieder
888 Added 'show all' command for yaz-client which retrieves all results
891 Added new yaz-client, xmles, which takes a (private) OID and
892 a document to be sent as an extended service request.
894 Describe new yaz-client commands wait_response and set_auto_wait.
896 Increase TCP/IP listener backlog from 3 (which I am guessing was
897 copied from the SunOS manual entry way back when) so SOMAXCONN, so
898 that the socket will queue as many incoming connections as it's able
899 to handle ongoing connections. In other words, it will never now
900 refuse a connection that it would be able to handle merely because
901 it's not got around to accepting() enough of the pending connections
902 yet. This is the behaviour anyway under Linux, where the listen()
903 argument is ignored; but not under BSD and on systems such as
904 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
905 YAZ-based servers should now be uniform across operating systems in
908 yaz-marcdump uses 64-bit file access on some systems. This is enabled
909 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
910 This allows yaz-marcdump to read large MARC batches (>2 GB).
912 Modified all YAZ source files - except the source which is auto-generated
913 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
916 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
917 corresponding to the existing *_setl() function. These allow option
918 values containing arbitrary valuues.
920 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
921 ZOOM_resultset_sort() in new applications. Its behaviour is identical
922 except that it returns an indicator of whether or not the sort
923 criterion was accepted (0 for OK, -1 for invalid).
927 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
928 MARC output rather than returning "new" buffer.
930 yaz-client warns about unknown init options.
932 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
936 Added support for SRW sort in Generic Frontend Server. Patch
937 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
938 sortKeys - or NULL if none is provided.
940 Fixed bug #307: It was impossible to specify indefinite/no timeout
941 for ZOOM_event. Special timeout value -1 now means indefinite timeout
944 Added support for multiple languages and charsets to be specified in
945 ZOOM. Each charset/language is separated by a blank. If negotiation is
946 in effect in init-response, Option
947 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
948 Code based on patch by Vasiliy Osadchuk.
950 Fixed bug #306: infinite recursion that occurred when calling
951 yaz_log_level_init as the first call (before other log level or
954 Fixed bug in scan handling in front end server: if preferred-Position-In-
955 Response was non-present, a NULL pointer referece was performed.
959 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
960 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
961 now defined for all those error codes. So instead of putting 109 in
962 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
963 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
965 Modified the yaz-marcdump utility to skip garbage bytes between MARC
968 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
970 Program yaz-client now exits and produces an error message if multiple
971 Z39.50 servers are specified on the command line (none or one allowed
974 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
979 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
981 Fixed bug #272: Preserve spacing for CCL terms.
985 Added support for virtual hosts and multiple backend servers for
986 the YAZ frontend server. The configution is XML based and
987 support specificition of CQL to RPN mappings and explain information.
988 See section "Virtual Hosts" in the YAZ manual.
990 Extended OPAC display utility. OPAC display utility renders
991 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
992 to supplement yaz_marc_decode_wrbuf.
994 Fixed a bug in MARC decoder that could caused it to crash for some
995 invalid MARC records. More diagnostics and warnings where added in
996 XML output (warnings, etc are stored in comments).
998 --- 2.0.34 2005/02/08
1000 Fixes for UNIX domain sockets. Bug #261.
1002 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1004 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1005 Added yaz_marc_subfield_str which defines subfield lead string which is
1006 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1007 yaz_marc_endline_str which defines end of fields string used in
1008 YAZ_MARC_LINE format. Default string is newline.
1010 Experimental support for MarcXChange. This format can be produced
1011 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1012 http://www.bs.dk/standards/MarcXchange.xsd
1014 Added yaz-client commands scansize that sets maximum number of
1015 entries to be returned by scan.
1017 --- 2.0.32 2005/01/11
1019 Added support for SRW scan in yaz-client and Generic Frontend Server.
1021 * Added whereInList member to SRW Scan Term.
1023 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1025 Fixed NMEM system to return aligned blocks on the smallest boundaries
1026 that are suitably aligned for all possible types on the particular
1027 architecture YAZ is being built for.
1029 --- 2.0.30 2005/01/04
1031 Fixed numerious warnings that was issued with newer versions of GCC.
1033 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1034 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1037 Make YAZ Generic Frontend Server slightly faster.
1039 Enhance (and reduce) logging for Generic Frontend Server.
1041 Revert YAZ log system so that it flushes every write operation
1042 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1044 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1045 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1046 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1047 will effectively disable old definitions.
1049 --- 2.0.28 2004/11/09
1051 Added yaz_log_time_format which specifies log format using
1054 Added yaz_log_module_level which returns mask for a module. Value
1055 is non-zero mask a if module is enabled; zero if disabled.
1057 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1058 in include/yaz/cql.h.
1060 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1062 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1064 Fixed bug #172: RPM builds does not enable SSL.
1066 Doxyfile.in part of dist. Doxyfile generated by configure.
1068 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1069 are given and the corresponding component does not exist.
1071 Extend CCL documentation in YAZ reference. Describe r=r.
1073 --- 2.0.26 2004/10/01
1075 Fixed MARC->MARCXML conversion to properly deal with
1076 fields, subfields, indicators having non-ASCII characters.
1078 Fixed MARC->MARCXML conversion so that ASCII control characters
1079 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1082 Added YAZ GFS support for conversion from Z39.50 surrogate
1083 diagnostics to SRW surrogate diagnostics.
1085 Bug fix: YAZ GFS did not return schema in explainResponse.
1087 --- 2.0.25 2004/09/30
1089 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1090 now converts recordSchema to elementSetName as well as schema URI.
1092 Fixed bug in COMSTACK that prevented HTTP request packages from being
1095 --- 2.0.24 2004/09/29
1097 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1098 does not require white-space before and after the dash in a range, e.g.
1099 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1102 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1103 due to new GCC removing "redundant" code.
1105 Added yaz-client commands scanpos and scanstep that sets preferred
1106 position and step-size for scan.
1108 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1110 Added CCL utility ccl_qual_buf which parses one or more CCL
1111 spec lines in a buffer.
1113 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1114 of name and value - ignoring empty lines and comments.
1116 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1118 Added odr_get_element_path which returns current element path for an
1119 ODR handle. This utility is useful in error handling or user-defined
1122 Added ODR_PRINT utility odr_set_stream which is is a more generic
1123 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1124 to a write function and pointer to close function. The close function - if
1125 non-NULL - will be called during odr_destroy.
1127 Fixed bug in CCL parser where truncation char was not removed from
1128 right side when truncation=both was in effect.
1130 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1133 --- 2.0.23 2004/08/11
1135 Fix buffer overrun in CQL parser when dealing with proximity (%).
1137 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1138 to UTF-8/UCS conversion is now only based on codetables.xml.
1140 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1142 --- 2.0.22 2004/08/06
1144 Add support for more "commit changes" in ZOOM (uses Extended Services).
1146 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1149 Yet another small fix for configure of SSL.
1151 --- 2.0.21 2004/05/14
1153 Fix SSL libs for configure when --with-openssl=DIR is given.
1155 --- 2.0.20 2004/05/10
1157 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1159 SSL comstack now uses yaz.pem certificate file on server side
1160 by default. Certificate filename can be configured by calling
1161 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1163 Fix bug regarding multiple calls to ZOOM_connection_connect.
1165 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1167 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1168 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1170 ZOOM now allows inspection of X509 peer certificate for verification.
1171 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1173 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1174 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1175 as "modular" but it simplifies things.
1177 Added cs_get_peer_certificate to that returns peer X509 PEM.
1179 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1180 NULL if SSL is unavailable.
1182 Documentation about MARC decoding tools.
1184 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1186 --- 2.0.19 2004/03/30
1188 Rename CHANGELOG to NEWS to follow GNU style packing.
1190 Fix bug with missing initialization of member in init_diagnostics.
1191 This bug affects threaded version of GFS server.
1193 --- 2.0.18 2004/03/20
1195 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1198 Ensure zlib.dll is packed with Windows install.
1200 --- 2.0.17 2004/03/17
1202 Fix encoding of xsd:string to use text instead of CDATA.
1204 Fix endless loop in CQL parser with unbalanced ".
1206 Use a more compact way to store MARC-8 conversion tables.
1208 --- 2.0.16 2004/03/16 Debian only
1210 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1213 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1218 --- 2.0.15 2004/03/01
1220 Another fix for decoding of XML packed records.
1222 --- 2.0.14 2004/02/25
1224 Fixes for Chunked encoding. White space not ignored after length spec.
1226 Update NS and use default NS for SRW diagnostic elements.
1228 --- 2.0.13 2004/02/23
1230 Implement ZOOM_resultset_cache_reset which resets record cache.
1232 Implement ZOOM_resultset_sort which sorts a result set.
1234 Implement chunked HTTP transfer.
1236 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1238 --- 2.0.12 2004/02/16
1240 Added member 'schema' to bend_explain_rr structure so that backend
1241 can specify explain record identifier. Defaults to Zeerex 2.0.
1243 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1245 --- 2.0.11 2004/02/16
1247 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1250 Added init command for yaz-client which sends "extra" init request.
1252 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1253 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1255 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1257 Make ZOOM error code for "invalid query".
1259 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1261 --- 2.0.10 2004/02/05
1263 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1266 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1268 Added option -p <file> to make Generic Frontend Server to write PID file.
1270 Added option -D to put Generic Frontend Server in background on its own.
1272 Make ZOOM C recognize option "password". If unset, "pass" is used
1273 (for backwards compatibility).
1275 Fixed a bug in Generic Frontend Server that could make it crash if a
1276 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1279 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1280 Must be issued before open, in order to be in effect.
1282 --- 2.0.9-6 2004/01/12 Debian/Windows
1284 Make the SRU server more picky WRT unknown params, etc.
1286 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1288 New YAZ client command, options, that sets Z39.50 options.
1290 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1291 options from a string of tokens (one token for each option bit).
1293 Update SRW diagnostic code messages.
1295 --- 2.0.9-5 2004/01/07 Debian/Windows
1297 Handle user defined stylesheet for SRW/SRU.
1299 --- 2.0.9-4 2004/01/06 Debian/Windows
1301 Fix bug in decoding of Content-Length.
1303 --- 2.0.9-3 2004/01/06 Debian/Windows
1305 Fix a bug with decoding of XML packed records.
1307 --- 2.0.9-2 2004/01/05 Debian only
1309 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1311 Fix bug in SRW/SRU diagnostics decoding.
1313 --- 2.0.9 2004/01/05
1315 Fixed bug in Generic Frontend Server which could drop records exceeding
1316 preferred message size. Reported and fixed by Irina Dijour.
1318 Fixed calculation of package size for structured records in Generic
1319 Frontend Server. Reported and fixed by Irina Dijour.
1321 Fixed namespace for SRW/SRU diagnostics.
1323 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1325 --- 2.0.8 2003/12/22
1327 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1328 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1331 CQL changes to reflect recent changes to the specification:
1332 * Documentation talks about context sets instead of index sets.
1333 * Documentation talks about indexes instead of qualifiers.
1334 * The CQL-to-PQF transformer's configuration file now uses
1335 "index.set.name = <attributes>" instead of the old form
1336 "qualifier.set.name = <attributes>". (Both forms are still
1337 understood but the latter is deprecated.)
1338 * CQL terms with no explicit index specified are now interpreted as
1339 cql.serverChoice instead of srw.serverChoice (which of course
1340 behaves exactly the same.)
1342 --- 2.0.7 2003/12/16
1344 MARC conversion can now generate ISO2709 output in another
1345 character set. yaz-marcdump uses this facility if you invoke it
1348 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1349 functions from there can be used from C++.
1351 --- 2.0.6 2003/12/04
1353 Frontend server now transfers memory from decoded packages to stream
1356 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1357 references to show up.
1359 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1360 the ZOOM Abstract API. The older names for the same options are still
1361 also supported for the benefit of old applications.
1363 ZOOM-C supports "implementationId" and "implementationVersion" options
1364 to go along with "implementationName". These allow the user code to
1365 specify identification strings to be sent to servers.
1366 Add OID for the new ExtLite attribute set.
1368 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1369 as requested/supplid by Ere Maijala <ere@atp.fi>
1371 For generic frontend server, reverse the order of
1372 "toolkit-supplied / application-supplied" strings sent as implementationId,
1373 Name and Version. Also, remove the spaces around the slash. This brings
1374 the GFS in line with the behaviour of ZOOM-C on the client side.
1376 Add function ZOOM_scanset_display_term.
1378 yaz-client shows scan displayTerm if present.
1380 Utility yaz-iconv is now installed by default along with the man page
1383 Extend configure check for OpenSSL to use pkg-config where available (such
1386 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1387 server to specify uid/gid/mask for socket using the format
1388 unix:[user=uid,][group=gid,][umask=mask,]file=path
1389 If file= is omitted the existing format is assumed, e.g.
1391 in which case the mask is 0666 (rw for everybody).
1393 Major restructure of YAZ source. All source in libyaz is in src directory.
1394 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1395 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1397 Added man page for utility yaz-marcdump (used to be called marcdump).
1398 yaz-marcdump is installed by 'make install'.
1400 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1401 of incoming package failed.
1403 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1405 Change prototype of odr_perror: add const to message string.
1407 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1409 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1410 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1411 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1412 DNS lookup. There should not be any compatibility problems with this
1413 assuming that blocking=1 or 0 is used.
1415 Fix bad reference in UNIX comstack in function cs_addrstr.
1417 Fix for compilation on AIX.
1419 The generic front-end server (server/seshigh.c) now supports returning
1420 Init diagnostics to the client in User-information-field, in
1421 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1424 --- 2.0.4 2003/09/04
1426 Allow any CQL relation (not just all,any,exact,scr).
1428 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1429 that features the same UI.
1431 Implemented command update0 in YAZ client which is equivalent to
1432 update but uses old of Ext Update ASN.1.
1434 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1435 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1436 Previously no OID was used for this info.
1438 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1439 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1440 returns 'malformed search term' otherwise.
1442 SortResponse member resultCount now set to NULL in sort handler of
1445 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1448 Add three new utility functions for translating OIDs between various
1449 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1450 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1451 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1452 char *oid_to_dotstring(const int *oid, char *oidbuf);
1453 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1455 Reverted modifications for ES Update definition for z_IU0Update
1456 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1457 is back to YAZ 2.0.2.
1459 String value attributes for CCL parser.
1461 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1462 which their FirstSearch server returns in Init responses, sometimes
1463 carrying useful diagnostic information when Init fails. This has the
1464 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1465 "z39.50/oclcui.asn", where its definition is somewhat different from
1466 what OCLC document on their web-site, as required to interoperate with
1469 Support for anonymous authentication in yaz-client. Use the command
1472 * Fix the OID of the Index Data-local "admin" Extended Service from
1473 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1474 the 1000, which indicates a locally-defined OID, was a mistake.
1476 --- 2.0.3 2003/06/20
1478 Fix CCL directive @case handling so that it affects string match for
1479 both CCL keywords and qualifiers.
1481 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1482 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1483 Decoder has been updated with ASN.1 changes as listed in
1484 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1485 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1486 z_IUUpdate, remains unchanged.
1488 ZOOM_record_get may now return a record in a specific character set.
1489 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1490 "from" is the character set of record as returned by target. "to" is
1491 the character set to be returned. If omitted, "to" is UTF-8.
1493 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1495 New ODR utility, odr_getelement, which returns name of element for
1496 which encoding/decoding failed.
1498 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1499 in cases where a required element was omitted.
1501 Bug fix: some MARC8 sequences were not converted.
1503 New ZOOM option "step" which specifies number of records to be
1504 retrieved in one chunk. Used in conjunction with "start" and "count".
1506 SRW support for yaz-client. Use scheme http: to use it, e.g.
1509 yaz-client no longer does (un)intelligent character set conversions
1510 by default. Can be enabled with charset and marc_charset commands.
1512 xmalloc trace fix for 64-bit systems such as DEC alpha.
1514 Solaris 2.6 compile fix.
1516 New function, cql_strerror() translates SRW error codes, as returned
1517 by cql_transform_error(), into human-readable English strings. Used
1518 in yaz-client diagnostics when appropriate.
1520 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1521 converts it into a type-1 query which is sent to the server. This
1522 makes CQL available for use with all Z-servers, as opposed to the tiny
1523 minority that can handle CQL queries themselves.
1525 --- 2.0.2 2003/04/28
1527 New Debian package layout similar to the Redhat Package layout.
1529 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1530 and search result respectively.
1532 --- 2.0.1 2003/04/25
1534 Redhat package is now several packages: libyaz (runtime libraries),
1535 libyaz-devel (development and documentation, and yaz (utility programs).
1536 Package spec file by Morten Bogeskov.
1538 New member 'schema' in struct bend_fetch_rr which the name of requested
1539 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1540 handler MAY set this to reflect the schema of the returned record.
1542 New member 'display_term' in struct scan_entry. GFS now sets member entries
1543 and allocates scan entries to be filled by user scan handler. In previous
1544 version, entries member was allocated by the scan handler. That still works,
1545 but the GFS will ignore member display_term - assuming it was NOT set by
1546 the handler. The fact that the GFS now allocates the entries both allows
1547 for new members and makes a scan handler easier to write.
1549 Fix CQL lex buffer overflow.
1551 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1552 SRU default recordPacking is string.
1554 SRU protocol support for frontend server.
1556 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1558 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1560 Added scan for the ZOOM shell (zoomsh).
1564 * String Identifers for Schemas (Amendment 5).
1565 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1566 Old definition for schema
1567 Odr_oid *schema; /* OPT */
1572 Z_InternationalString *uri;
1573 #define Z_Schema_oid 1
1574 #define Z_Schema_uri 2
1577 * resultCount parameter to Sort Response (Amendment 1).
1578 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1580 Support for SRW 1.0 over HTTP. This is an optional feature and
1581 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1584 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1585 on the same port. SRW SearchRetrieveRequests are mapped
1586 to bend_init,bend_search,bend_fetch,bend_close.
1588 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1590 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1591 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1593 ZOOM connections are SRW based if schem http is used for hostname
1594 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1595 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1597 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1598 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1599 distance=n, order=true/false, relation=le, prox unit=word. If
1600 n is omitted, distance 1 is used.
1602 Fixed problem with C compiler include path in wrong order.
1604 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1605 on Solaris. Patch from Ko van der Sloot.
1607 New MARC decode API. All new functions operate on a yaz_marc_t
1608 handle. The most important new functions are: yaz_marc_create,
1609 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1610 decode and destroy respectively. Decoder can produce formats
1611 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1612 include/yaz/marcdisp.h.
1614 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1615 to UTF-8, UCS-32, wchar_t or Latin-1.
1617 * Prototypes for yaz_iconv_-functions moved to separate header
1618 include/yaz/yaz-iconv.h.
1620 Make a few private functions 'static' in unix.c. This prevents
1621 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1623 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1624 are set when Init Response is received.
1626 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1627 but returns diagnostic set as well.
1629 New function yaz_strerror which is a portable wrapper for
1630 strerror/strerror_r/GetLastMessage.
1632 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1633 is returned for MARC. If type is "oai", then OAI MARC is returned.
1635 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1638 --- 1.9.2 2002/11/26
1640 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1642 Fix bad race conditions on SIGTERM and terminate gracefully in
1645 Move retrieval (data1) module to Zebra since nobody seems to be
1648 Add GRS-1 render for ZOOM using same format as yaz-client.
1650 --- 1.9.1 2002/10/05
1652 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1654 Fix broken ESpec handling in data1 module.
1656 SGML reader parses comments and makes them part of the data1 tree.
1658 Added several type casts so that YAZ compiles as C++ code.
1660 ZOOM didn't handle PDU encoding failures properly.
1662 Added more Bib-1 diagnostics (approved extensions).
1664 GNU configure: better check for iconv.
1666 More portable use of accept, getpeername. Check for socklen_t. Use
1667 int/size_t if socklen_t is not defined.
1671 PQF parser rejects bad queries - including those with extra
1672 characters in them. PQF parser used to silently ignore that.
1673 Cleaner API for PQF added, which allows you to get detailed
1674 error information for bad queries (see yaz/pquery.h).
1676 Fixed bug in ZOOM_record_get for type "database".
1678 Implemented mini iconv library supporting conversions between
1679 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1681 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1683 --- 1.8.9 2002/08/20
1685 Fixed ZOOM C record cache so that preferredRecordSyntax and
1686 elementSetName is used to check for already fetched records.
1688 --- 1.8.8 2002/08/02
1690 Added three members in bend_initrequest structure to facilitate
1691 character set negotiation.
1693 Fixed a bug in frontend server that could cause indefinite
1694 loops under rare conditions.
1696 Revised character set utilities (charneg.h) so that encoding
1697 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1699 For PQF, directive @term <type> sets term type for Scan/Search.
1700 Here <type> is general, string, numeric, null. The term type
1701 is inherited - just like @attr.
1703 New call odr_set_charset that sets character set conversion for
1704 international-strings on a ODR stream. Prototype is:
1705 int odr_set_charset(ODR o, const char *to, const char *from);
1706 The InternationalString is still represented as C string in YAZ
1707 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1708 won't). On the protocol level, you can use any encoding.
1710 Support for UNIX sockets in ZOOM.
1712 Solaris recv sometimes returns errno == ENOENT. It is treated as
1713 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1715 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1716 both client and server. Code by Morten Bogeskov.
1718 --- 1.8.7 2002/05/22
1720 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1721 that they can be used directly from Visual Basic. You must recompile
1722 your windows APP if you're using ZOOM.
1724 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1725 Commands "lang" and "charset" sets language and character set respectively.
1726 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1727 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1729 Attributes from multiple CCL fields may be OR'ed rather than merged
1730 using directive "@field or". Fields are still merged by default -
1731 equivalent to "@field merge".
1733 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1736 Fixed bug in zget for parameter ExtendedServicesResponse.
1740 --- 1.8.6 2002/03/25
1742 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1744 Client displays USR.1:SearchResult-1 (hits per term).
1746 Additional Search Info for search in Generic Frontend Server.
1748 Fixed CCL parsing of "field=s".
1750 WIN32 installer - using the excellent NSIS software from nullsoft.
1752 Fixed CCL parsing of "field = - <number>".
1754 Added function yaz_marc_decode that decodes MARC for line mode
1755 display or XML (similar to that used by JZKit).
1757 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1758 Z39.50. But ISO/ILL was, however.
1760 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1761 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1763 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1764 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1766 --- 1.8.5 2002/02/03
1768 New YAZ client features: Command completion and new commands:
1769 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1770 Code provided by Jacob Poulsen.
1772 New call oid_trav, that visits all registered OIDs via callback.
1774 Function ZOOM_record_get now returns const char pointer rather than
1775 void pointer. It saves a lot of type casts.
1777 For YAZ client, command "auth" now allows you to set authentication
1778 in IdPass style. It is enabled when three tokens are given - order
1779 is user, group and password.
1781 Fix memory leaks in MARC record handling for ZOOM.
1783 New option for YAZ client, -k <kilobytes> that sets
1784 maximum record size. Similar to -k option for generic frontend
1785 server and yaz-ztest.
1787 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1789 Prefix query parser reports "fail" when bad attribute set is given.
1791 Fix in MARC decoder. Proximity logging. Fix for attribute set
1792 in scan handler for server. Patches by Shigeru Ishida.
1794 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1797 Configure option --with-openssl=<dir> now works when a directory is
1798 specified. Patch provided by Morten Bogeskov.
1800 New option for YAZ client, -u <auth>, that sets authentication.
1802 ZOOM fix: error information was sometimes "missing", since error
1803 was cleared/reset too when it shouldn't.
1805 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1807 --- 1.8.4 2002/01/04
1809 Scan for ZOOM API. New object ZOOM_scanset. New functions
1810 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1811 ZOOM_scanset_destroy.
1813 New ZOOM function, ZOOM_connection_last_event, that returns type
1814 of last event (such as "receive data", "send data", "apdu received",
1817 New ZOOM option, schema, that specifies schema for retrieval.
1819 New CCL feature. Qualifiers can be aliases for one or more
1820 other qualifiers (if more than one is given, OR is used).
1822 ZOOM uses named result sets if target supports it.
1824 Two new YAZ client commands: . (dot, which sources a script of YAZ
1825 client commands), and ! (to execute shell command.). Implemented
1828 Working on Debian packages.
1830 --- 1.8.3 2001/11/19
1832 YAZ client enables named result sets only if target supports it.
1834 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1836 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1837 with key="host" to get same result.
1839 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1840 Function Z3950_resultset_record(s) returns references to records
1841 "owned" by resultset. To become owner use Z3950_record_clone.
1843 Function z_ext_record handles Extended Services. Thanks to
1846 --- 1.8.2 2001/11/12
1848 CCL Parser fix: ignore token comma when dealing with and-lists.
1850 Documentation updates for COMSTACK.
1852 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1853 Changed prototype Z3950_records. For some functions, int parameters
1854 were changed to size_t.
1856 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1859 New MARC decode/display function, marc_display_exl, which properly rejects
1860 non-ISO2709 records. YAZ client uses it.
1862 --- 1.8.1 2001/10/29
1864 Fix bug: local attribute set wasn't set correctly in PQF strings.
1868 * Old Z39.50 codecs no longer supported.
1870 Added ZOOM C binding. See http://zoom.z3950.org/
1872 Renamed states for COMSTACKs to avoid confusion with events.
1874 Implemented cs_look and proper cs_rcvconnect.
1876 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1878 Configure detects POSIX threads on OpenBSD.
1880 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1881 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1883 When error is returned from present handler, non-surrogate diagnostic
1884 is returned in present response (and fetch handler is no longer called).
1886 * Minor adjustments to pquery parser (PQF). Token characters may be
1887 escaped by using backslash (C-style).
1889 PQF parser allows string attribute values to be specified. For @attr,
1890 non-numeric characters after the equal-sign are treated as strings
1891 (e.g. @attr 9=title).
1893 CCL trunction character may be defined (@truncation in file)
1895 * function zget_ExtendedServicesRequest sets waitAction to
1896 waitIfPossible (was wait).
1898 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1901 CCL operator names may be set in field definition files (CCL_bibset).
1902 See ccl/bib1 for an example.
1904 Fixes in ASN.1 compiler for C++ compatibility.
1906 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1907 and "op_or" to avoid conflict with C++.
1909 Fixed problem with GNU readline detection on Redhat 7.0.
1911 Added step-size for Scan backend handler.
1913 Fixed bug that made the frontend server crash when no attribute
1914 set was specified for scan.
1916 Front-end server automatically switches to original working directory
1917 when installed as an NT service. Previously -w had to be specified to
1920 Added extended attributes for retrieval module (data1), so that data1
1921 records carry d1_readXML/SGML attributes. d1_read also supports
1922 null-data rules ( <tag/>)
1924 On UNIX when POSIX threads are available, a separate library libyazthread
1925 is created. Programmers should link with that library and the yaz library
1926 when using threads. The reason for the split was that some applications
1927 on Linux, such as Apache, doesn't work well when using shared objects that
1930 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1931 (or any frontend server) in SSL mode by specifying ssl: followed by
1932 address. Only tested on UNIX.
1934 Added feature for CCL module. Virtual structure s=al or s=ol generates
1935 and-list and or-list respectively instead of phrase search.
1939 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1940 log_mask_str. This was done to avoid name conflicts with other libraries
1941 (such as other PHP extensions).
1943 Added raw OID member for preferred record syntax (request_format_raw)
1944 and returned record syntax (output_format_raw) for backend fetch method.
1946 Config file yaz-config now accepts options so that it returns specific
1947 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1949 Shared library support for UNIX using GNU libtool.
1951 * Modified backend interface. Request/Response struct's replaced by
1952 one read/write C struct. For example bend_fetchrequest and
1953 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1954 Every handler - even search has to be registered in bend_init
1955 handler. This means that the YAZ library no longer refers to
1956 external functions and it makes it possible to make the whole
1957 thing a single DLL/SO.
1959 Added Segment handler for backend server.
1961 Added Zmbol/Zebra administrative functions to YAZ client.
1963 Threaded frontend server on UNIX (when POSIX Threads are available).
1964 Starting the server with option -T enables multi-threading.
1968 Added configure option --enable-comp/disable-comp to control use
1969 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1970 located in sub directory asn.
1972 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1973 in ${exec_prefix}/bin along with the other programs yaz-client and
1976 GNU automake used to maintain makefiles.
1978 Added several OID's.
1980 Changed retrieval module so that we can load records with no abstract
1981 syntax defined. Tagpaths in these records are fully composed of string
1984 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1988 On UNIX, the generated makefile now supports a proper 'make install'.
1989 The prefix can be set via GNU configure to set the install location
1990 (default is /usr/local).
1992 * YAZ programs client and ztest were renamed to yaz-client and
1993 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1994 locations, such as /usr/bin,/usr/local/bin,etc.
1996 * YAZ Header files were moved from include to include/yaz. YAZ Header
1997 files are referred to as include <yaz/log.h> rather than <log.h>.
1998 The YAZ include path (-I ..) is therefore the same as before. Programmers
1999 should update their #include statements or use -Ipath/include/yaz
2000 instead. The main motivation for doing this change is that YAZ header files
2001 can be installed in "standard" locations /usr/include,/usr/local/include
2002 without introducing conflicts, since ALL YAZ header files are stored
2003 in subdirectory yaz (under /usr/include for example).
2005 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2006 rather than project/workspace files. We switched because project files
2007 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2010 Changed name of logging function, logf, to yaz_log, to prevent name
2011 clash with some math-log functions. The YAZ header log.h defines logf
2012 to yaz_log (#define) so there should be no incompatibilities by this
2015 Added bend_start/bend_stop handlers for server. These handler are
2016 called on start/stop of server. For windows they are called whenever
2017 a service is started/stopped.
2019 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2020 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2021 in util/yc.tcl. The auto-generated C code structures are, in a few
2022 cases, incompatible with the old decoders. There are differences in the
2023 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2024 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2025 The preprocessor variable ASN_COMPILED is defined when the compiled
2026 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2027 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2028 wish to use the old encoders/decoders you can specify --disable-yc
2031 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2032 version so that it supports both new - and old version of DB Update
2034 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2035 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2036 change. The name parameter can be set to 0 in which no name is specified
2037 for the construction. The macros odr_implicit and odr_explicit sets name
2038 parameter to zero for the construction involved. New macros
2039 odr_implicit_tag and odr_explicit_tag are similar to the others,
2040 except that a name parameter is added. For programmers' that don't use
2041 ODR they probably only need to change the call to z_APDU and z_External.
2043 Added access control facility by interfacing the TCP wrapper library.
2044 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2045 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2046 name of the daemon and enables the access control as specified in
2047 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2049 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2050 den Dool <H.M.vdnDool@kub.nl>.
2052 Added reference ID parameter to most functions in server API - refer
2053 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2055 Changed name of ccl library to libccl.a (was ccl.a).
2057 Fixed bug in decoder for Explain (Category TargetInfo).
2059 Added support for GNU readline in client. Thanks to Jacob Poulsen
2060 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2062 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2063 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2064 IMPLEMENTATION! This change was made to the development version before
2065 the ZIG decided to retract the amendment. If any users MUST be
2066 compatible with the original Update definition, PLEASE CONTACT US, and
2067 we will include a separate definition corresponding to the old Update
2068 ES. Note that because of the change to the ASN.1 of the
2069 TaskPackageRecordStructure we cannot define a single structure that
2070 will support both versions.
2072 * Added const modifier to buffer parameter for some ODR/BER encoding
2073 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2074 completeWAIS, odr_dumpBER.
2076 Fixed bug in client.c which caused a crash when a scanResponse didn't
2077 contain positionOfTerm.
2079 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2080 * will cause an error in a client if a non-YAZ target sends both a
2081 * list of Scan entries and non-surrogate diagnostics.
2083 Retrieval module enhancements. Tag sets may be typed in the reference
2084 to it. From the .abs-file the "tagset" directive takes a third optional
2085 integer type for the tag set referenced. From a .tag-file the "include"
2086 directive takes a third optional type as well. The old "type" directive
2087 in the tag set itself is still recognized but acts as the default type
2090 Backend interface change. Individual Scan terms returned from bend_scan
2091 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2092 in include/backend.h.
2094 Retrieval module enhancements. Multiple tag sets and attribute sets may
2095 be specified in abstract syntax specs. Revised the error/warning for
2096 logging messages reported by the retrieval module when reading the
2099 Object Identifier system (oid_..) changed. The API is backwards
2100 compatible but the oid-routines now allocates new OID's when needed.
2101 Raw OID's may be specified in oid_getvalbyname.
2103 YAZ now uses GNU configure to generate Makefile(s).
2105 * Minor changes in some of the member names of DeleteResultSetRequest and
2106 DeleteResultSetResponse. See include/proto.h.
2108 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2109 and added member 'languages' in TargetInfo (which was missing).
2111 Changed the way attribute sets are handled in the retrieval
2112 module. These are now cached, just like the abstract syntaxes
2115 Changed YAZ so that it links with compiled ASN.1.
2117 Added Explain-schema definitions and mapping routines. The following
2118 Explain categories have been implemented: AttributeDetails,
2119 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2121 Fixed minor bug in Windows version of Server Library.
2123 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2125 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2127 Added EXTERNAL: UNIverse Resource Report (non-standard).
2129 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2130 ENUMERATED and SET OF.
2132 * Added 'const' to some of the char pointer arguments for the
2133 functions, data1_read_node, data1_getelementbytagname,
2134 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2137 Fixed bug in data1_insert_taggeddata - the last_child member of
2138 parent wasn't initialised.
2140 * Changed data1_read_record and data1_read_node so that the supplied
2141 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2142 doesn't refer to any parts of the "SGML"-buffer.
2144 Fixed bug in server library (Windows version of statserv_remove).
2146 * Changed code so that it compiles as C++. The type definition
2147 of Odr_fun which is a member of Odr_arm was changed. The result is,
2148 that an explicit typecast is needed for the fun pointer when
2149 using Odr_arm - as in:
2150 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2152 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2154 Implemented the new structured date and time definition as approved
2155 by the ZIG. Added schemaId element to the specificTag in Espec-1
2156 (also approved at the last ZIG). Thanks to RVDM.
2158 Added some Object identifiers (RVDM).
2160 Changed the Update Extended Service (RVDM).
2162 Added command "refid" to client which specifies referenceId for
2163 the following requests.
2165 Implemented extended service handling for server. See ztest.c
2166 for an example as well as backend.h. New handlers are registerd
2167 in the Init handler.
2169 * Changed interface for sort in server.
2171 Added new members to statserv_options_block. It allows a server
2172 to read options from another source than just the command line. Thanks
2173 to Charles Woodfield.
2175 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2176 renamed to zboolean. Some C++ compilers complained about the name.
2178 Minor changes to gils.abs. Added index 's' (sort) on title
2179 and date/time-last-modified.
2181 --- 1.4pl2 1998/1/30
2183 Fixed bug in server library regarding inetd mode (-i). This bug
2184 was introduced by release 1.4.
2186 --- 1.4pl1 1998/1/29
2188 Added sort facility in client and backend server interface.
2190 Fixed problem with dependencies in Makefile(s).
2192 Fixed bugs for encoders/decoders of extended services and
2195 Implemented sub-tree feature for schemas. Sub-trees are
2196 referenced in *.abs-files. See explain.abs for an example
2197 of the use of this feature.
2199 Modified bib1.att; local attributes for ANY didn't include
2200 ANY itself (only affects use of the retrieval module).
2202 Fixed bug in plain SGML reader in function data1_read_node:
2203 tags with prefix "var" was incorrectly interpreted as variants.
2205 Added feature "sub-schemas" to enable references to - and definitions
2206 of - group of elements.
2208 * Removed member parent from type data1_element (in data1.h).
2210 Implemented function odr_nullval() that returns the value of
2213 * Removed member num_children from data1_node (in data1.h).
2215 Made NT service interface part of the server library. The
2216 function statserv_main uses the NT service when required and
2217 calls the statserv_start / statserv_close routines.
2219 Routine zget_SearchRequest and zget_PresentRequest fills
2220 resultSetName/Id member with "default" instead of "Default".
2222 Fixed memory leak in server. Request queue member wasn't freed.
2224 Fixed nmem_exit so that memory is freed.
2228 Revised the CCL parser utility to be thread safe.
2230 Added function, oid_ent_to_oid, to replace the function
2231 oid_getoidbyent, which is not thread safe.
2233 * Added nmem_init and nmem_exit to initialize and release
2234 NMEM resources. Function nmem_init should be called once in the
2235 initial thread before NMEM/ODR is used. statserv.c and client.c
2236 have been changed accordingly. The change was necessary to make
2237 NMEM thread safe. The NMEM memory pool is shared amongst threads
2238 in a process. Unix-based applications will still work fine without
2241 Added NT Services interface for the the Z39.50 (statserv) Server.
2242 Refer to the ztest.c source on the usage.
2244 Windows 95/NT port using MSVC5.0. Project files are included in the
2247 * Defined new 'global' handle for the retrieval (data1) system. The
2248 new handled, data1_handle, describes the state of the data1 system.
2249 This handle is passed as first argument to virtually all
2250 data1 related routines. The functions data1_create and data1_destroy
2251 creates and destroys a data1 handle respectively.
2253 Added ODR encode stream member to all backend request structures
2254 init, search, scan etc. This stream should be used to allocate all
2255 memory used for the response when thread safe operation is needed.
2257 Changed the comstack utility, cs_addstr, to be thread safe. The
2258 returned hostname string returned by the function is now part the
2261 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2262 function. The cs_straddr takes a COMSTACK handle as argument, so this
2263 function must be used after cs_create and before bind/connect.
2264 This function is thread safe.
2266 Moved test server to 'ztest' directory - generic server code still
2267 in 'server' directory.
2269 Made prefix query (pquery.c) utility thread safe.
2271 Added new function modifier YAZ_EXPORT to 'export' public DLL
2272 functions when using windows (see include/yconfig.h).
2274 Added definitions to the OID database (util/oid.c) (RVDM).
2276 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2278 Added call to ccl_rpn_delete in client program.
2280 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2281 release of RPN structure.
2283 Added support for C++, headers uses extern "C" for public definitions.
2284 With input from RVDM.
2286 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2287 Thanks to Ronald van der Meer (RVDM).
2289 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2291 Added support for private extensions to the OID database
2292 (oid_setprivateoids()). Thanks to RVDM.
2294 Added optional, physical ANY (key replication)
2296 Fixed null-reference problem in GRS-1 output filter.
2298 Proximity operator added to Prefix Query Format (PQF).
2300 In test client command "base" accepts multiple databases.
2302 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2306 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2308 Smallish bug-fixes in the new encoders/decoders (explain).
2310 Bug fixed in DeleteRequest.
2312 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2314 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2316 Added SOIF syntax (using private OID for now) to retrieval module and client.
2318 Added Update extended service.
2320 Added SearchResult-1 additional info structure.
2322 Added optional CCL (ISO8777) interpreter as separate module. Available
2325 --- 1.2 1996/6/10 (1st anniversary release)
2327 Added Summary record syntax. Lightly tested.
2329 Added OPAC record syntax. Untested.
2331 Added ResourceReport service encoders/decoders. Untested.
2333 Fixed bug in z_Unit - wrong tagging on unitSystem.
2335 Fixed bug in the DiagRecs decoder.
2337 Added options for max PDU size and session timeout to frontend-server.
2339 Added documentation of query-language parsers and other supporting utilities.
2341 [frontend-server] Added Attribute set to the bend_scanrequest API.
2343 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2344 surrogate diagnostics were generated.
2346 [retrieval] Allow multiple local values for attribute.
2348 [retrieval] Allow multiple attributes per element in .abs files. index type.
2350 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2352 --- 1.1pl2 1996/4/10
2354 Minor changes, mostly specific to Zebra's requirements (retrieval)
2358 Repaired bug in frontend server when running multiple listening
2359 endpoints in dynamic mode.
2361 z_External() now won't break if a known, ASN.1 value comes encapsulated
2362 in an octet-string. The value will pass through unmodified in an Odr_oct.
2364 Added a bit of code to the demo client to decode & display
2365 ASN.1-structured records represented in the octet-aligned branch of
2366 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2368 Added z_ext_getentbyref() to the ASN module. Doc updated.
2370 * Completed the SCAN definition in the ASN module. This may break SCAN
2371 code based on older YAZ-versions at compile-time. The fix is easy -
2374 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2375 under the SCAN definition. Remember to initialize this, server-people.
2377 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2378 that this does not extend to ODR and ASN.
2380 Comstack allows insertion of established socket (primarily for
2381 inetd-operation of servers). Doc updated.
2383 Front-end server can now start from the inetd in TCP mode. Doc
2386 --- 1.0pl4 1996/1/24
2390 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2391 the rank and record number.
2393 Adjustments to the frontend server.
2395 Fixed diagnostic BER dumper. It ignored the file argument.
2399 Various changes to retrieval module.
2401 Changed the union discriminators of the protocol files from enums to
2402 ints paired with #defines.
2404 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2407 *Changed operator in the RPN structure to 'roperator', again to avoid a
2410 Fixed problems in Explain decoders/encoders.
2412 --- 1.0pl2 1995/12/6
2414 Memory bug in log module fixed.
2416 --- 1.0pl1 1995/12/5
2418 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2420 Bug in Explain DatabaseInfo module fixed.
2422 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2426 The shift to v1.0 signals that we now consider the *core* functionality
2427 of YAZ reasonably stable (the core being more or less equivalent to
2428 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2429 tested (Explain not at all - though that will happen soonish).
2431 Minor changes to code to support Windows port.
2433 Various minor changes after we're getting to use GRS-1 & co. more.
2435 Added Espec-1 format.
2437 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2438 of the protocol and it cannot be selected when encoding (maps into 'string'
2439 when decoding). Needed to talk to some servers.
2441 Demo client can request simple element set names.
2443 Added Diagnostic Format encoders/decoders.
2445 Added simple Close handling to frontend server (no hooks for resource
2446 reporting yet), and demonstration client.
2448 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2450 --- 1.0b3 1995/08/24
2452 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2453 handled incorrectly when records were requested in the searchResponse. This
2454 will only affect you if you use the frontend-server.
2456 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2457 Test-client will ask for and print GRS1. Ztest will return dummy records
2460 Added Explain encoders/decoders to the service-level API. Untested.
2462 Added Extended Services: Item Order encoders and decoders to the Service-
2463 level API. Untested. We could use a recent copy of the pertinent bits
2464 of the ILL protocol to add those bits.
2466 Added diagnostic format 1 encoders/decoders to the service-level API.
2469 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2470 odr_cons.c, which causes a more correct output.
2472 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2473 was always set to 0 when no records were requested in the searchRequest.
2475 * Added better external-handling. This shouldn't harm old code that
2476 *encodes* externals. It can break code that looks for a
2477 'single-ASN1-type' representation, since those types that are known
2478 are now decoded immediately. Look at the SUTRS sample code in
2479 seshigh.c and client.c. Documentation updated.
2481 Handling of structured records in bend_fetchresponse. Length -1 marks
2482 structured record, type is deduced from format field.
2484 --- 1.0b2 1995/06/27
2485 Fairly quick maintenance release to add SUTRS support.
2487 Fixed handling of SUTRS records in the demonstration client.
2489 * Added format field to the bend_fetchrequest and bend_fetchresponce
2490 structures of the backend API (frontend server). When the record is
2491 returned, the value of the format field is mapped to an OID. The
2492 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
