3 yaz-client emits a better message when receiving an unrecognised
8 Function yaz_xml2query allows a diagnostic element in the PQF XML
9 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
10 code and additional info respectively.
12 The BER BOOLEAN is now the integral type Odr_bool which still happens
13 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
14 typedef'd to Odr_int. This is still an integral 'int', but it may be
15 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
16 ASN-1 compiler as well as programs has been updated to use the new types.
20 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
21 only the bibliographic record was rendered. For type=opac, an OPAC
22 record is only returned if it is present.
24 iconv: small fix for encoding of advancegreek.
26 yaz-client: avoid double display of SRU/SRW records (bug #2798).
28 yaz-client: option auto_reconnect=on really reconnects.
30 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
32 server: avoid null ptr ref for for yaz_poll errors.
34 build: fix RPM build for RHEL 5.3.
36 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
40 Fixed bug #2709: TCP connect returns Invalid argument.
42 Fixed compilation for mingw.
44 Honor charset for raw records (ZOOM_record_get).
46 Fixed use of errno for threaded mode that was seen on Solaris 10.
48 Fixed argument passing with blanks in value for Windows Service.
50 Disable YAZ' own log rotate by default (no 1 GB limit).
51 The variable l_max_size which specifies the log file limit is set to 0
52 (DISABLED): This is due to the fact that YAZ is most often deployed using
53 logrotate. Also YAZ can not perform log rotate because of unsufficient
58 List supported encodings in man page for yaz-iconv.
60 Fixed missing SSL libs for --libs output
62 Re-established OID record syntax application-xml. Nobody should use it
63 but we don't want to change soname because of this symbol being absent.
67 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
69 Added member named_result_sets for init handler struct for the GFS. This
70 allows a server to disable named result sets.
72 Removed OID record syntax application-xml.
74 Added support for rule-based transliterator for ICU wrapper of YAZ.
76 Fixed bug #1902: yaz-icu XML output.
78 Make YAZ checks Emacs friendly.
80 BITSTRING value shows value. Bug #2346.
82 ISO2709 decoding: skip control characters from indicator data.
84 Omit sort key by default in yaz-icu's output.
86 Allow combined single char options (again) for YAZ' options function.
88 Utility yaz-marcdump got option to display YAZ version (-V).
90 Allow YAZ to use ICU 3.4.
92 Added new ICU test case which illustrates removal of diacritics.
96 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
100 For configure, using option --without-xml2 also disables Libxslt/Libexslt
103 Fixed bug #2352: yaz-marcdump crashes for certain record.
105 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
107 Added support for Danmarc2 to UTF-8 conversion.
109 Added support for ISO5426 to UTF-8 conversion.
111 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
112 implementation version.
114 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
116 --- 3.0.38 2008/11/10
118 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
119 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
121 ZOOM C now interprets databaseName option for ZOOM connection as path
124 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
126 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
128 Dummy Libxml2 types no longer defined in headers of YAZ'.
130 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
133 --- 3.0.36 2008/09/26
135 Various ODR chapter fixes.
137 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
139 Added missing source for Windows compilation, mutex.c.
141 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
143 For SRU connections in ZOOM all records up to "count" are now fetched.
145 Fixed crash in generic frontend server (and yaz-ztest) which occurred
146 in Windows due to bad error handling for Libxml2.
148 Added facility for sending arbitrary records (ASN.1 any) using
149 ZOOM C's Extended service update. Patch by Sam Reynolds.
151 New options for ZOOM C's connection, logapdu which makes ZOOM log
154 --- 3.0.34 2008/06/18
156 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
158 --- 3.0.32 2008/06/12
160 Fixed memory violation that could occur when decoding UTF-8. This bug
161 was only present in 3.0.30 of YAZ.
163 --- 3.0.30 2008/06/06
165 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
166 GNU TLS is used by default (if found).
168 yaz-ztest returns OPAC records if a client asks for OPAC.
170 Improved speed of MARC-8 encoding.
172 Added support for lossy and loss-less MARC-8 encoding.
174 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
176 Added new Windows Service wrapper (sc).
178 yaz-client's itemorder command may now send a file.
180 Fixed yaz-marcdump to allow the use of NS prefix for record element.
182 Added new function yaz_log_xml_errors.
184 Allow (but warn) unknown XML attributes in MARCXML parsing.
186 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
188 The UTF-8 to MARC-8 conversion now uses a different set of characters
189 for Greek symbols. Bug #2120.
191 --- 3.0.26 2008/02/21
193 Added yaz_daemon (daemon.h).
195 Fixed bug #2068: pkg-config trouble
197 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
199 --- 3.0.24 2008/01/28
201 Document --with-xml2 option.
203 Added OPAC XML XSD (etc/opacxml.xsd).
205 Allow glob mask for name attribute in retrieval element for the
206 generic frontend server's retrieval facility.
208 Changed yaz_poll_poll to return yaz_poll_except for all returned events
209 except POLLIN/POLLOUT.
211 Fixed error handling in cs_listen. Bug #2037.
213 --- 3.0.22 2008/01/20
215 Fixed version in yaz/yaz-version.h.
217 Fixed bug #2027: Crash when closing connection.
219 Changed configure so that ICU support is only enabled if only ICU
220 and Libxml2 is available (because the ICU chain is XML based).
222 --- 3.0.20 2008/01/15
224 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
225 is built. Only this DLL depends on the ICU runtime.
227 yaz-ziffy is no longer part of YAZ. It is distributed separately by
228 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
230 Changed license of CCL module to 'Revised BSD'. After consultation with
231 remaining members of the original EUROPAGATE consortium, we are re-issuing
232 the CCL module without a separate license. The software was developed by
233 Index Data as part of a research project. The special license was included
234 to help feed usage information back to the project consortium to support
235 project evaluation. At this time, the project consortium has long-since
236 disbanded, and the majority of the original principals have retired. At the
237 same time, we have significantly modified the software during the following
238 years, to the point where very practically no original code remains. To
239 simplify re-use of the software, we have contacted those members of the
240 consortium who could be reached, and agreed to re-issue the module as a
241 proper part of the YAZ package.
243 Tcl scripts uses /usr/bin/tclsh as preferred shell.
245 CQL closer to being version 1.2 compliant. CQL also allows free-form
246 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
249 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
250 bug could make Extended services handling crash in the ZOOM layer. This
251 bug was only present in YAZ 3.0.18.
253 --- 3.0.18 2007/12/19
255 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
258 yaz-marcdump reads and writes collection wrapped records.
260 Handle OPAC for record conversion module.
262 Fixes for ICU wrapper.
264 Allow ICU libs to be controlled with --with-icu .
266 --- 3.0.16 2007/11/12
268 Added yaz_poll which is a wrapper for select/poll. When poll is available
269 and non-buggy, it is used, by yaz_poll . This allows more than 1024
270 sockets to be in use.
272 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
273 functionality through an XML based configuration (ICU chain). This system
274 is useful for search facilities such as Pazpar2 and Zebra that needs to
275 perform tokenization of indexed material. The ICU code in a separate
276 library libyaz3_icu.a.
278 Added HTTP tunnel facility for COMSTACK, bug #1752.
279 This is a facility that allows a Web proxy, such as squid, to tunnel
280 Z39.50 traffic. This facility is "transparent" to must applications
281 using YAZ. It's enabled by using pseudo transport connect: followed by
282 the proxy address, followed by command, then follwed by he regular
283 "virtual" addresss. For example,
284 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
286 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
288 --- 3.0.14 2007/09/21
290 Fixed bad memory reference in ZOOM_record - cuased by member not being
291 initialized. This was a problem only in YAZ 3.0.12.
293 Fixed bug in conversion from MARC to XML: Non-XML characters in control
294 fields were not removed.
296 Changed the way C code is generated from codetables.xml. Made a MARC-8
297 conversion trie for each characterSet section rather than codeTable.
298 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
299 of codetables.xml from Larry Dixson, LOC. Bug #1464.
301 --- 3.0.12 2007/09/12
303 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
304 from ZOOM_record_error).
306 ZOOM C function ZOOM_record_get returns record schema for type="schema".
308 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
310 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
312 Better SRW-to-Bib-1 diagnostic mapping.
314 ZOOM C and yaz-client announces SRU version 1.2 by default.
316 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
319 Fixed in yaz_sru_decode to allow other version than 1.1.
321 --- 3.0.10 2007/08/22
323 Added support for SRU scan for ZOOM.
325 Added support for the use of the older versions or Extended Service
326 Update in ZOOM. To faciliate this, an option "updateVersion" may be
327 set to the version , 1=first, 2=second, 3=third. The third version is
328 what ZOOM C has used so far. And that, obviously, is the default.
330 Added support for CCL queries in Z39.50 queries sent to the GFS (and
331 therefore in Zebra and in SimpleServer-based applications). The new
332 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
333 qualifier file used to transform incoming CCL queries into Type-1 RPN,
334 which is passed into the back-end search callback function.
336 Added support for HTTP Basic authentication in clients: the SRU/W
337 codec encodes the username/password elements of the PDU structure
338 appropriately, and these may be set using the "user" and "password"
339 options in ZOOM-C applications (the same options that are used for
340 Z39.50 authentication).
344 Fixed bug #1208: SSL appears to be broken in ZOOM.
346 Fixed bug #1206: Libxml2 include path weirdness.
348 Added oid_name_to_dotstring.
350 Allow elementSetName to be specified for ZOOM C record update.
352 Allow waitAction to be specified for ZOOM C based for Extended Services.
354 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
355 syntax OID. Bug introduced in YAZ 3 series.
357 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
361 Fixed bug #1157: yaz-client does not read .yazclientrc from current
362 directory. yaz-client now reads commands from file given by option -f
363 if specified; then tries to read .yazclientrc in current directory.
364 Failing that, it reads .yazclientrc from user's home directory.
366 Added support for correlationInfo Note and ID for Record Update via
369 Added yaz-client command querycharset which specifies character set for
370 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
371 (termListAndStartPoint).
373 Charset ISO5428:1984 is an alias for ISO5428-1984.
375 Implemented a way to perform scan in a result set using Z39.50. This
376 is achieved by attaching the result set name in the characterInfo
377 (type InternationalString) of OtherInformation in the Scan Request PDU.
378 The result set is identified in the otherinformation by the new OID:
379 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
380 This allows for scan in result set and faceted search . Zebra did some
381 of this in the APT term using attribute type 8 and value being result
382 set. Using the OtherInformation approach for this is cleaner and easier
383 to work with in proxies and the like. This facility can be used in
384 yaz-client using new command setscan which takes a result set as first
385 argument, start position (APT) as second.
387 Changed decoding of SRU XML packed records to deal with servers that
388 have recordData with XML data with multiple root nodes. Also make
389 comparison for recordPacking case insensitive. Again, one server
390 returns "XML" where others return "xml".
392 For SRU responses allow Content-Type application/xml as well as text/xml.
396 Fixed bug in character set conversion of BER strings. Bug introduced
401 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
403 For OID class, use oid_class consistently.
405 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
408 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
409 character set for bibliographic information interchange". By Giannis Kosmas.
411 Added documentation on new OID API.
415 Changes to generic frontend server interface: added new member
416 'query_charset' for bend_initrequest structure. A backend init handler
417 should set this member to its native character set for query terms.
418 When defined, the frontend server logic will announce this character set
419 to a client if the negotiationModel bit is set by the client. All server
420 implementors are encouraged to specify this. If a backend server does not
421 specify this a warning is issued using yaz_log(YLOG_WARN,..).
423 Added CCL utility to remove terms (stop words) from resulting RPN
424 tree. This is handled by functions with prefix ccl_stop_words_ .
426 New ZOOM C option, "rpnCharset", which allows client-side conversion of
427 terms in RPN queries.
429 Clean-up the CCL API. Moved some internal structures from ccl.h to
430 private header cclp.h. Changed ccl_parser_create so that a Bibset must
431 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
432 This is replaced by ccl_parser_find_str which takes a string instead.
434 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
435 libyaz.la is the core of YAZ except the generic frontend server and
436 does not depend on POSIX threads anymore. libyaz_server.la is the
437 generic frontend server facilities and uses POSIX thread functionality
438 if available. The libyaz.la no longer depends on POSIX threads because
439 the number of global structures is limited. NMEM no longer re-uses blocks
440 between threads ; it simply free's memory immediately but allocates in
441 "large" chunks as usual. We don't expect any performance penalties
442 because of this. The yaz_log system is still using a global log_level so
443 caution must be taken when modifying it with yaz_log_init_.. +
444 yaz_log_mask_str. This, however, should not cause any trouble because
445 these functions are called during initialization of application code
446 anyway. `yaz-config --libs server` returns libs for server applications;
447 `yaz-config --libs` returns libs for non-server applications.
449 New OID database - with public definitions in oid_db.h. Removed old OID
450 database including the head oid.h and definitions such as enum oid_value
451 and struct oident. The new OID database uses the same string names as
452 before but the 'protocol' is gone. There are now only two representations
453 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
454 converts from string to OID; functions with prefix yaz_oid_to_string
455 converts the other way.
457 Change to emit_term() in CQL-to-PQF query translation: when a term has
458 the /regexp relation modifier, do not process it for leading and
459 trailing "^" and "*", which have quite different meanings in regular
462 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
463 write handlers no longer carries a 'last' parameter. This will make
464 yaz_iconv flush "less" characters. A flush is performed by call to
465 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
467 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
468 removed, because function yaz_query_to_wrbuf does the same.
470 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
471 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
473 Deprecated MARC utility functions removed.
475 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
478 Branch split: YAZ_2_1_55_branch
480 --- 2.1.54 2007/03/16
482 Fix to ZOOM-C so that transparent reconnection is properly handled on
483 connections that are in asynchronous mode.
485 Fixed compilation on OpenBSD 4.0.
487 Large strings in GRS-1 records are now properly displayed in yaz-client.
489 Added character conversion support for "advancegreek"; based on patch from
492 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
493 sequence is met. Before the error was not set so it would be unknown.
495 Adjust yaz-marcdump MARC reader so that it skips until record separator
498 --- 2.1.52 2007/03/07
500 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
501 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
502 fd_set structure used as a bitmask for the FDs to be selected on.
504 Using ACX_PTHREAD macro to check for POSIX threads.
506 Fixed have-vsnprintf check.
508 --- 2.1.50 2007/02/23
510 Fixes for configure on BSD. Bug #900.
512 Added snprintf/vsnprintf wrappers for systems that don't have
513 limits (heavens forbid).
515 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
516 created before all previous tasks were completed and removed from the
517 task queue, the new task could be removed by a mistake.
519 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
521 Implemented pass-through CQL-to-PQF conversions. Bug #861.
523 Fixed bug #832: Problem with MARC/charset in yaz-client.
525 Fixed bug #668: save command line history for yaz-client.
527 Fixed bug #830: pkg-config support.
529 --- 2.1.48 2007/01/23
531 Extended ZOOM result set options with two options that may be read by
532 a client: resultSetStatus and presentStatus with values as specified for
534 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
536 Fixed bug #827: Using SSL fails on Debian etch.
538 Fixed bug #826: Weird looking chars for set of MARC records.
540 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
541 that is treated as an ItemOrder with itemRequest being an XML document
542 external. The value of "doc" is the content.
544 Extended the GFS search facility. New member of bend_search_rr
545 'estimated_hit_count' signals that hits is known to be an estmate
546 (higher or lower than real hit count). New member 'partial_resultset'
547 signals that the search was partial (hit count is lower or equal than
548 real hit count). For Z39.50, the information is stored in resultSetStatus
549 member of SearchResponse APDU. For SRU, the information is signalled
550 via SRU diagnostic 59: "Result set created with valid partial results
553 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
555 --- 2.1.46 2007/01/13
557 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
559 Added ZOOM_connection_peek_event.
561 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
562 the following new functions:
563 ZOOM_event_nonblock, ZOOM_connection_process,
564 ZOOM_connection_get_{socket,mask,timeout},
565 ZOOM_connection_fire_event_{timeout,socket}.
566 The existing blocking event handler, ZOOM_event, is a wrapper for the
567 + blocking ZOOM_event_sys_{poll,select}.
569 Implemented function ccl_xml_config which parses XML version of CCL
570 configuration (bug #798).
572 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
574 Added timings utility (yaz/timing.h)
576 --- 2.1.44 2007/01/03
578 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
581 Fixed bug #779: Rotation of apdu.log fails.
583 Fixed for character set conversions:
584 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
585 Honor G1 set in MARC-8 decoding.
587 --- 2.1.42 2006/12/17
589 Fixed bug #775: char conversion does not handle Alternative UTF-8
592 Implemented function yaz_marc_read_line which parses MARC line format
593 records. There is a wealth of formats out there. So far, this function
594 reads line records produced by yaz_marc_write_line.
596 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
597 more generic and easier to remember(!) options: -i format and -o format
598 which specifies input format and output format respectively - where
599 format is one of "marc", "marcxml", "line", "marcxchange".
601 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
602 does not print anything except warnings for records.
604 For yaz-marcdump, added support for MARC split into files (-s) with a given
607 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
608 spec, at http://www.loc.gov/standards/sru/record-update/
609 This has changed the binary layout of the following structs:
610 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
611 bend_update_rr . Patch by Ko van der Sloot.
613 Added GFS utility function bend_assoc_is_alive which returns 1 if
614 association is still alive (client is connected); 0 otherwise (client
615 closed connection). This allows busy servers to stop working for
618 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
619 been a separate piece of software. This version of ziffy has been modified
620 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
622 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
624 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
625 Client code may now interrogate options such as "init_opt_sort" to
626 find out whether the server claims to support various options.
628 --- 2.1.40 2006/11/27
630 Added utilities yaz_{set,get}_esn to set/get element set name from
633 Removed the build of libyazthread.la. The libyaz.so is the threaded version
634 of YAZ and has been so since YAZ 2.1.10.
636 Implemented ZOOM_record_error which returns error information for
637 record (surrogate diagnostic).
639 --- 2.1.38 2006/10/31
641 Updates for SRU Update by Ko van der Sloot:
642 1. Changed name from "operation" to "action"
643 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
644 versions in the code, marked as 'backward compatible'.
645 3. Added diagnostics for SRU Update.
647 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
649 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
651 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
653 For GFS, fixed problem with SRU diagnostic 'First record position out of
654 range' being issued for 0 hits.
656 zoomtst10 part of Windows Build.
658 --- 2.1.36 2006/10/13
660 Implemented yaz_filepath_comp which splits a path into file path
661 components (required by Zebra 2.0.3+).
663 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
664 BSD inspired license until now so this should not have any real impact on
665 anybody. See http://www.opensource.org/licenses/bsd-license.php
667 Fixed bug #687: Missing log lines.
669 Fixed bug #678: CQL to PQF translation does not preserve double-quote
672 Fixed bug #689: SRU diagnostics to be added.
674 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
675 whether a connection is idle (no more work do do).
677 --- 2.1.34 2006/10/04
679 Change type of optval from long to int for invocation of setsockopt with
680 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
682 Added support for specifying the max log file size for the Generic
683 Frontend Server. The size is given with option -r.
685 --- 2.1.32 2006/09/21
687 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
689 --- 2.1.30 2006/09/17
691 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
694 Fixed bug in Generic Frontend Server that could cause a server to stop
695 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
697 For the generic frontend server, the maximum record size is used as maximum
698 size of incoming packages (SRU + Z39.50). The value until was previously
699 only used in Z39.50 Init negotiation and, later, in a session controlled
700 sizes of records returned. This is controlled using -k option. It can be
701 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
703 --- 2.1.28 2006/09/04
705 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
708 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
710 New option for yaz-marcdump -lpos=value which allows setting a portion
711 of MARC header to a certain value.
713 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
715 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
716 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
718 --- 2.1.26 2006/08/15
720 Fixed problem with SRU mode type (soap, get, post) for yaz-client
723 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
725 --- 2.1.24 2006/08/08
727 Fixed MARC ISO2709 encoding routines to deal with character set
730 Minor changes to GFS logging. Database included in search request log
733 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
734 cached/multiple records.
736 Shared libraries are built by default on Unix+configure.
738 Changed cql2pqf transformation to use a different evaluation order. The
739 new order is: always, relation, structure, position, truncation, index
740 and relationModifier. Old order was: always, relation, relationModifier,
741 structure, index, position, truncation. Note that the the latter ones
742 override former ones for identical attributes.. The new scheme means that
743 it is possible to override any existing attribute with a relationModifier.
744 And also that it is possible to override everything for the index rule
745 (except the ones listed in relationModifier). No order is perfect but this
746 one, we believe, covers more real cases.. The "always" should have been
747 called "default", since the attributes there can be overridden with all
750 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
751 compilation phase, but also for yaz-config --cflags output. This allows
752 us to have public headers with Libxml2 stuff in them . It should also,
753 eventually, make Libxml2 checks redundant in packages using YAZ, such
756 --- 2.1.22 2006/06/15
758 Changed SRU update structure bend_update_rr so that SRU diagnostics are
759 stored in uri, message and details.. Previously diagnostics were stored
760 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
761 compatibility.. but he's probably the only one affected, so.
763 Added support for CCL, compiled on the client side, in ZOOM-C. This
764 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
765 input; the resulting query objects can be used for for searching with
766 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
768 YAZ' configure searches for OpenSSL by default.
770 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
771 SL_CTX_use_certificate_file. See
772 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
773 for more info. Thanks to Ko van der Sloot.
775 --- 2.1.20 2006/06/02
777 Bug #600: SRU GET, POST support for yaz-client. Introduced
778 command 'sru' which selects method SOAP/GET/POST.
780 Allow missingValueAction to be specified for the sortspec string -
781 function yaz_sort_spec. By default, the missing value action is null.
782 Use ! to specify "abort". Use = followed by stringvalue to specify default
785 Ensured that Present-handler (if defined) is called in GFS before any call to
786 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
787 searchRetrieve requests.
789 Documentation for YAZ is now based on the Docbook XML/XSLT using
790 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
791 is no longer depending on jade/openjade or docbook-to-man scripts.
792 PDF is no longer part of the distribution - but can optionally be
793 made using DSSSL/jadetex or FOP.
795 Added retrieval handling support in Generic Frontend Server to support
796 conversion between MARC/XML as well as XSLTtransforms. See
797 etc/yazgfs.xml for an example.
799 Added Authentication support to Generic Frontend Server in SRU
800 mode. Authentication using HTTP Basic is supported, as is the use
801 of 'x-username' and 'x-password' parameters in the request itself.
803 Added support for a new character set MARC8s identical to MARC8 except
804 that it converts combined characters to single Unicode characters in the
805 Latin-1 range (when possible).
807 --- 2.1.18 2006/04/24
809 ASN.1 compiler 0.4: generates brief Doxygen file header for
810 generated .h/.c files.
812 Utility yaz_iconv now supports conversion to MARC-8.
814 New facilities for the MARC module. The reading - and writing of
815 content are separate methods for the yaz_marc_t handle. The following
816 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
817 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
818 format). Write functions have prefix yaz_marc_write_.. The existing
819 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
820 available. Removed support for OAI-MARC and simplexml (not the
821 simplexml from PHP5).
823 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
824 to be returned for this connection.
826 --- 2.1.16 2006/03/31
828 Allow multiple languages and charsets to be specified with
829 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
830 negcharset iso-8859-1,utf-8
832 Translation of proximity nodes from CQL into PQF now works.
834 Moved to automake 1.8, 1.9.
836 Added function yaz_log_set_handler which allows a log handler to be
837 installed. This handler will be called for all log messages. Output
838 to file is also produced; but that can be disabled by passing NULL
839 fname to yaz_log_init_file.
841 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
843 For SRW (including GFS), accept application/soap+xml as content-type
846 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
847 produces NO stylesheet reference even if a default stylesheet is specified
850 --- 2.1.14 2006/03/14
852 Updated Windows package to include yazd.dll + yazd.lib for the
853 Development component.
855 If the environment variable YAZ_LOG is set, then it is used as a
856 string indicating the default level of logging to use if not
857 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
858 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
859 used as before. So, for example, to omit warnings from YAZ logging,
862 cql_transform() now map structure and other attributes before indexes,
863 so that index-specific structures and other attributes can override
864 defaults. So now a combination of mapping specifications such as:
866 index.dc.date = 1=date-modified 4=5
867 does the right thing.
869 cql_transform() now also respects the "always" mapping specification,
870 which establishes an initial set of attributes to be used for all
871 terms except where overridden by more specific attributes associated
872 with the index, relation or modifier.
874 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
875 which mode to use; one of "post", "get" or "soap" (SRW, default).
877 Fixes for yaz_iconv routines: changed trie-based character set conversions
878 to use only non-negative values for bit fields due to Sun's C compiler not
879 supporting negative values.
881 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
882 sequences where not read correctly. Fix by Rustam Usmanov.
884 Updated win/makefile to use options, settings which makes things
885 compile with VS C 2005.
887 --- 2.1.12 2006/02/01
889 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
891 In ZOOM socket code, use select instead of poll on MacOSX.
893 ZOOM-C now support client-side compilation of CQL into RPN that is
894 sent to the server, enabling CQL to be used against all Z39.50
895 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
896 ZOOM_query object, and submit it using ZOOM_connection_search().
897 The CQL-to-RPN translation uses a configuration file, the name of
898 which must be specified in the Connection's "cqlfile" option.
900 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
901 function, which takes as its start-term parameter a ZOOM_query object
902 (which may have had either CQL or RPN set into it).
905 --- 2.1.10 2005/11/29
907 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
908 GFS to support this as well. Backend handler, bend_srw_update, does the
909 update work. Code contributed by Ko van der Sloot.
911 Allow retrieval of Search Result-1 information in ZOOM by the use of
912 options that are attached to a result set. ZOOM documentation updated
915 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
916 UTF-8 conversion. Patch by Raj Patel.
918 Added option -m to GFS to control formatting of timestamps in log file.
920 Added 'exit' as synonym for 'quit' in yaz-client
922 Added support for specifying SRW resultSetId + resultSetIdleTime in a
923 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
924 for the new members. Patch by Ko van der Sloot.
926 Added support for SRU POST. It is supported for content-type
927 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
929 Do not build the separate Multi-threaded (MT) library libyazthread.la.
930 Instead make the library libyaz.la multi-threaded. Threading as a whole
931 can still be disabled by configure option --disable-threads. Previosly,
932 with older GLIBCs there were problems with MT libs under Apache. This
933 has now been fixed a long time ago.
935 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
938 CQL module modified to be case insensitive for relations/indexes/operations.
940 Fixed bug in CQL transform code: incorrect value relationModifieder
943 Added 'show all' command for yaz-client which retrieves all results
946 Added new yaz-client, xmles, which takes a (private) OID and
947 a document to be sent as an extended service request.
949 Describe new yaz-client commands wait_response and set_auto_wait.
951 Increase TCP/IP listener backlog from 3 (which I am guessing was
952 copied from the SunOS manual entry way back when) so SOMAXCONN, so
953 that the socket will queue as many incoming connections as it's able
954 to handle ongoing connections. In other words, it will never now
955 refuse a connection that it would be able to handle merely because
956 it's not got around to accepting() enough of the pending connections
957 yet. This is the behaviour anyway under Linux, where the listen()
958 argument is ignored; but not under BSD and on systems such as
959 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
960 YAZ-based servers should now be uniform across operating systems in
963 yaz-marcdump uses 64-bit file access on some systems. This is enabled
964 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
965 This allows yaz-marcdump to read large MARC batches (>2 GB).
967 Modified all YAZ source files - except the source which is auto-generated
968 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
971 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
972 corresponding to the existing *_setl() function. These allow option
973 values containing arbitrary valuues.
975 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
976 ZOOM_resultset_sort() in new applications. Its behaviour is identical
977 except that it returns an indicator of whether or not the sort
978 criterion was accepted (0 for OK, -1 for invalid).
982 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
983 MARC output rather than returning "new" buffer.
985 yaz-client warns about unknown init options.
987 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
991 Added support for SRW sort in Generic Frontend Server. Patch
992 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
993 sortKeys - or NULL if none is provided.
995 Fixed bug #307: It was impossible to specify indefinite/no timeout
996 for ZOOM_event. Special timeout value -1 now means indefinite timeout
999 Added support for multiple languages and charsets to be specified in
1000 ZOOM. Each charset/language is separated by a blank. If negotiation is
1001 in effect in init-response, Option
1002 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1003 Code based on patch by Vasiliy Osadchuk.
1005 Fixed bug #306: infinite recursion that occurred when calling
1006 yaz_log_level_init as the first call (before other log level or
1009 Fixed bug in scan handling in front end server: if preferred-Position-In-
1010 Response was non-present, a NULL pointer referece was performed.
1012 --- 2.1.4 2005/04/26
1014 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1015 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1016 now defined for all those error codes. So instead of putting 109 in
1017 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1018 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1020 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1023 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1025 Program yaz-client now exits and produces an error message if multiple
1026 Z39.50 servers are specified on the command line (none or one allowed
1029 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1032 --- 2.1.2 2005/03/16
1034 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1036 Fixed bug #272: Preserve spacing for CCL terms.
1038 --- 2.1.0 2005/03/14
1040 Added support for virtual hosts and multiple backend servers for
1041 the YAZ frontend server. The configution is XML based and
1042 support specificition of CQL to RPN mappings and explain information.
1043 See section "Virtual Hosts" in the YAZ manual.
1045 Extended OPAC display utility. OPAC display utility renders
1046 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1047 to supplement yaz_marc_decode_wrbuf.
1049 Fixed a bug in MARC decoder that could caused it to crash for some
1050 invalid MARC records. More diagnostics and warnings where added in
1051 XML output (warnings, etc are stored in comments).
1053 --- 2.0.34 2005/02/08
1055 Fixes for UNIX domain sockets. Bug #261.
1057 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1059 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1060 Added yaz_marc_subfield_str which defines subfield lead string which is
1061 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1062 yaz_marc_endline_str which defines end of fields string used in
1063 YAZ_MARC_LINE format. Default string is newline.
1065 Experimental support for MarcXChange. This format can be produced
1066 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1067 http://www.bs.dk/standards/MarcXchange.xsd
1069 Added yaz-client commands scansize that sets maximum number of
1070 entries to be returned by scan.
1072 --- 2.0.32 2005/01/11
1074 Added support for SRW scan in yaz-client and Generic Frontend Server.
1076 * Added whereInList member to SRW Scan Term.
1078 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1080 Fixed NMEM system to return aligned blocks on the smallest boundaries
1081 that are suitably aligned for all possible types on the particular
1082 architecture YAZ is being built for.
1084 --- 2.0.30 2005/01/04
1086 Fixed numerious warnings that was issued with newer versions of GCC.
1088 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1089 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1092 Make YAZ Generic Frontend Server slightly faster.
1094 Enhance (and reduce) logging for Generic Frontend Server.
1096 Revert YAZ log system so that it flushes every write operation
1097 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1099 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1100 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1101 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1102 will effectively disable old definitions.
1104 --- 2.0.28 2004/11/09
1106 Added yaz_log_time_format which specifies log format using
1109 Added yaz_log_module_level which returns mask for a module. Value
1110 is non-zero mask a if module is enabled; zero if disabled.
1112 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1113 in include/yaz/cql.h.
1115 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1117 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1119 Fixed bug #172: RPM builds does not enable SSL.
1121 Doxyfile.in part of dist. Doxyfile generated by configure.
1123 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1124 are given and the corresponding component does not exist.
1126 Extend CCL documentation in YAZ reference. Describe r=r.
1128 --- 2.0.26 2004/10/01
1130 Fixed MARC->MARCXML conversion to properly deal with
1131 fields, subfields, indicators having non-ASCII characters.
1133 Fixed MARC->MARCXML conversion so that ASCII control characters
1134 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1137 Added YAZ GFS support for conversion from Z39.50 surrogate
1138 diagnostics to SRW surrogate diagnostics.
1140 Bug fix: YAZ GFS did not return schema in explainResponse.
1142 --- 2.0.25 2004/09/30
1144 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1145 now converts recordSchema to elementSetName as well as schema URI.
1147 Fixed bug in COMSTACK that prevented HTTP request packages from being
1150 --- 2.0.24 2004/09/29
1152 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1153 does not require white-space before and after the dash in a range, e.g.
1154 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1157 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1158 due to new GCC removing "redundant" code.
1160 Added yaz-client commands scanpos and scanstep that sets preferred
1161 position and step-size for scan.
1163 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1165 Added CCL utility ccl_qual_buf which parses one or more CCL
1166 spec lines in a buffer.
1168 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1169 of name and value - ignoring empty lines and comments.
1171 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1173 Added odr_get_element_path which returns current element path for an
1174 ODR handle. This utility is useful in error handling or user-defined
1177 Added ODR_PRINT utility odr_set_stream which is is a more generic
1178 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1179 to a write function and pointer to close function. The close function - if
1180 non-NULL - will be called during odr_destroy.
1182 Fixed bug in CCL parser where truncation char was not removed from
1183 right side when truncation=both was in effect.
1185 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1188 --- 2.0.23 2004/08/11
1190 Fix buffer overrun in CQL parser when dealing with proximity (%).
1192 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1193 to UTF-8/UCS conversion is now only based on codetables.xml.
1195 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1197 --- 2.0.22 2004/08/06
1199 Add support for more "commit changes" in ZOOM (uses Extended Services).
1201 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1204 Yet another small fix for configure of SSL.
1206 --- 2.0.21 2004/05/14
1208 Fix SSL libs for configure when --with-openssl=DIR is given.
1210 --- 2.0.20 2004/05/10
1212 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1214 SSL comstack now uses yaz.pem certificate file on server side
1215 by default. Certificate filename can be configured by calling
1216 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1218 Fix bug regarding multiple calls to ZOOM_connection_connect.
1220 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1222 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1223 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1225 ZOOM now allows inspection of X509 peer certificate for verification.
1226 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1228 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1229 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1230 as "modular" but it simplifies things.
1232 Added cs_get_peer_certificate to that returns peer X509 PEM.
1234 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1235 NULL if SSL is unavailable.
1237 Documentation about MARC decoding tools.
1239 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1241 --- 2.0.19 2004/03/30
1243 Rename CHANGELOG to NEWS to follow GNU style packing.
1245 Fix bug with missing initialization of member in init_diagnostics.
1246 This bug affects threaded version of GFS server.
1248 --- 2.0.18 2004/03/20
1250 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1253 Ensure zlib.dll is packed with Windows install.
1255 --- 2.0.17 2004/03/17
1257 Fix encoding of xsd:string to use text instead of CDATA.
1259 Fix endless loop in CQL parser with unbalanced ".
1261 Use a more compact way to store MARC-8 conversion tables.
1263 --- 2.0.16 2004/03/16 Debian only
1265 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1268 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1273 --- 2.0.15 2004/03/01
1275 Another fix for decoding of XML packed records.
1277 --- 2.0.14 2004/02/25
1279 Fixes for Chunked encoding. White space not ignored after length spec.
1281 Update NS and use default NS for SRW diagnostic elements.
1283 --- 2.0.13 2004/02/23
1285 Implement ZOOM_resultset_cache_reset which resets record cache.
1287 Implement ZOOM_resultset_sort which sorts a result set.
1289 Implement chunked HTTP transfer.
1291 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1293 --- 2.0.12 2004/02/16
1295 Added member 'schema' to bend_explain_rr structure so that backend
1296 can specify explain record identifier. Defaults to Zeerex 2.0.
1298 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1300 --- 2.0.11 2004/02/16
1302 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1305 Added init command for yaz-client which sends "extra" init request.
1307 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1308 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1310 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1312 Make ZOOM error code for "invalid query".
1314 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1316 --- 2.0.10 2004/02/05
1318 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1321 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1323 Added option -p <file> to make Generic Frontend Server to write PID file.
1325 Added option -D to put Generic Frontend Server in background on its own.
1327 Make ZOOM C recognize option "password". If unset, "pass" is used
1328 (for backwards compatibility).
1330 Fixed a bug in Generic Frontend Server that could make it crash if a
1331 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1334 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1335 Must be issued before open, in order to be in effect.
1337 --- 2.0.9-6 2004/01/12 Debian/Windows
1339 Make the SRU server more picky WRT unknown params, etc.
1341 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1343 New YAZ client command, options, that sets Z39.50 options.
1345 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1346 options from a string of tokens (one token for each option bit).
1348 Update SRW diagnostic code messages.
1350 --- 2.0.9-5 2004/01/07 Debian/Windows
1352 Handle user defined stylesheet for SRW/SRU.
1354 --- 2.0.9-4 2004/01/06 Debian/Windows
1356 Fix bug in decoding of Content-Length.
1358 --- 2.0.9-3 2004/01/06 Debian/Windows
1360 Fix a bug with decoding of XML packed records.
1362 --- 2.0.9-2 2004/01/05 Debian only
1364 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1366 Fix bug in SRW/SRU diagnostics decoding.
1368 --- 2.0.9 2004/01/05
1370 Fixed bug in Generic Frontend Server which could drop records exceeding
1371 preferred message size. Reported and fixed by Irina Dijour.
1373 Fixed calculation of package size for structured records in Generic
1374 Frontend Server. Reported and fixed by Irina Dijour.
1376 Fixed namespace for SRW/SRU diagnostics.
1378 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1380 --- 2.0.8 2003/12/22
1382 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1383 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1386 CQL changes to reflect recent changes to the specification:
1387 * Documentation talks about context sets instead of index sets.
1388 * Documentation talks about indexes instead of qualifiers.
1389 * The CQL-to-PQF transformer's configuration file now uses
1390 "index.set.name = <attributes>" instead of the old form
1391 "qualifier.set.name = <attributes>". (Both forms are still
1392 understood but the latter is deprecated.)
1393 * CQL terms with no explicit index specified are now interpreted as
1394 cql.serverChoice instead of srw.serverChoice (which of course
1395 behaves exactly the same.)
1397 --- 2.0.7 2003/12/16
1399 MARC conversion can now generate ISO2709 output in another
1400 character set. yaz-marcdump uses this facility if you invoke it
1403 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1404 functions from there can be used from C++.
1406 --- 2.0.6 2003/12/04
1408 Frontend server now transfers memory from decoded packages to stream
1411 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1412 references to show up.
1414 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1415 the ZOOM Abstract API. The older names for the same options are still
1416 also supported for the benefit of old applications.
1418 ZOOM-C supports "implementationId" and "implementationVersion" options
1419 to go along with "implementationName". These allow the user code to
1420 specify identification strings to be sent to servers.
1421 Add OID for the new ExtLite attribute set.
1423 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1424 as requested/supplid by Ere Maijala <ere@atp.fi>
1426 For generic frontend server, reverse the order of
1427 "toolkit-supplied / application-supplied" strings sent as implementationId,
1428 Name and Version. Also, remove the spaces around the slash. This brings
1429 the GFS in line with the behaviour of ZOOM-C on the client side.
1431 Add function ZOOM_scanset_display_term.
1433 yaz-client shows scan displayTerm if present.
1435 Utility yaz-iconv is now installed by default along with the man page
1438 Extend configure check for OpenSSL to use pkg-config where available (such
1441 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1442 server to specify uid/gid/mask for socket using the format
1443 unix:[user=uid,][group=gid,][umask=mask,]file=path
1444 If file= is omitted the existing format is assumed, e.g.
1446 in which case the mask is 0666 (rw for everybody).
1448 Major restructure of YAZ source. All source in libyaz is in src directory.
1449 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1450 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1452 Added man page for utility yaz-marcdump (used to be called marcdump).
1453 yaz-marcdump is installed by 'make install'.
1455 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1456 of incoming package failed.
1458 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1460 Change prototype of odr_perror: add const to message string.
1462 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1464 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1465 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1466 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1467 DNS lookup. There should not be any compatibility problems with this
1468 assuming that blocking=1 or 0 is used.
1470 Fix bad reference in UNIX comstack in function cs_addrstr.
1472 Fix for compilation on AIX.
1474 The generic front-end server (server/seshigh.c) now supports returning
1475 Init diagnostics to the client in User-information-field, in
1476 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1479 --- 2.0.4 2003/09/04
1481 Allow any CQL relation (not just all,any,exact,scr).
1483 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1484 that features the same UI.
1486 Implemented command update0 in YAZ client which is equivalent to
1487 update but uses old of Ext Update ASN.1.
1489 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1490 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1491 Previously no OID was used for this info.
1493 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1494 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1495 returns 'malformed search term' otherwise.
1497 SortResponse member resultCount now set to NULL in sort handler of
1500 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1503 Add three new utility functions for translating OIDs between various
1504 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1505 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1506 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1507 char *oid_to_dotstring(const int *oid, char *oidbuf);
1508 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1510 Reverted modifications for ES Update definition for z_IU0Update
1511 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1512 is back to YAZ 2.0.2.
1514 String value attributes for CCL parser.
1516 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1517 which their FirstSearch server returns in Init responses, sometimes
1518 carrying useful diagnostic information when Init fails. This has the
1519 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1520 "z39.50/oclcui.asn", where its definition is somewhat different from
1521 what OCLC document on their web-site, as required to interoperate with
1524 Support for anonymous authentication in yaz-client. Use the command
1527 * Fix the OID of the Index Data-local "admin" Extended Service from
1528 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1529 the 1000, which indicates a locally-defined OID, was a mistake.
1531 --- 2.0.3 2003/06/20
1533 Fix CCL directive @case handling so that it affects string match for
1534 both CCL keywords and qualifiers.
1536 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1537 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1538 Decoder has been updated with ASN.1 changes as listed in
1539 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1540 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1541 z_IUUpdate, remains unchanged.
1543 ZOOM_record_get may now return a record in a specific character set.
1544 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1545 "from" is the character set of record as returned by target. "to" is
1546 the character set to be returned. If omitted, "to" is UTF-8.
1548 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1550 New ODR utility, odr_getelement, which returns name of element for
1551 which encoding/decoding failed.
1553 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1554 in cases where a required element was omitted.
1556 Bug fix: some MARC8 sequences were not converted.
1558 New ZOOM option "step" which specifies number of records to be
1559 retrieved in one chunk. Used in conjunction with "start" and "count".
1561 SRW support for yaz-client. Use scheme http: to use it, e.g.
1564 yaz-client no longer does (un)intelligent character set conversions
1565 by default. Can be enabled with charset and marc_charset commands.
1567 xmalloc trace fix for 64-bit systems such as DEC alpha.
1569 Solaris 2.6 compile fix.
1571 New function, cql_strerror() translates SRW error codes, as returned
1572 by cql_transform_error(), into human-readable English strings. Used
1573 in yaz-client diagnostics when appropriate.
1575 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1576 converts it into a type-1 query which is sent to the server. This
1577 makes CQL available for use with all Z-servers, as opposed to the tiny
1578 minority that can handle CQL queries themselves.
1580 --- 2.0.2 2003/04/28
1582 New Debian package layout similar to the Redhat Package layout.
1584 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1585 and search result respectively.
1587 --- 2.0.1 2003/04/25
1589 Redhat package is now several packages: libyaz (runtime libraries),
1590 libyaz-devel (development and documentation, and yaz (utility programs).
1591 Package spec file by Morten Bogeskov.
1593 New member 'schema' in struct bend_fetch_rr which the name of requested
1594 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1595 handler MAY set this to reflect the schema of the returned record.
1597 New member 'display_term' in struct scan_entry. GFS now sets member entries
1598 and allocates scan entries to be filled by user scan handler. In previous
1599 version, entries member was allocated by the scan handler. That still works,
1600 but the GFS will ignore member display_term - assuming it was NOT set by
1601 the handler. The fact that the GFS now allocates the entries both allows
1602 for new members and makes a scan handler easier to write.
1604 Fix CQL lex buffer overflow.
1606 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1607 SRU default recordPacking is string.
1609 SRU protocol support for frontend server.
1611 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1613 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1615 Added scan for the ZOOM shell (zoomsh).
1619 * String Identifers for Schemas (Amendment 5).
1620 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1621 Old definition for schema
1622 Odr_oid *schema; /* OPT */
1627 Z_InternationalString *uri;
1628 #define Z_Schema_oid 1
1629 #define Z_Schema_uri 2
1632 * resultCount parameter to Sort Response (Amendment 1).
1633 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1635 Support for SRW 1.0 over HTTP. This is an optional feature and
1636 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1639 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1640 on the same port. SRW SearchRetrieveRequests are mapped
1641 to bend_init,bend_search,bend_fetch,bend_close.
1643 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1645 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1646 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1648 ZOOM connections are SRW based if schem http is used for hostname
1649 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1650 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1652 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1653 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1654 distance=n, order=true/false, relation=le, prox unit=word. If
1655 n is omitted, distance 1 is used.
1657 Fixed problem with C compiler include path in wrong order.
1659 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1660 on Solaris. Patch from Ko van der Sloot.
1662 New MARC decode API. All new functions operate on a yaz_marc_t
1663 handle. The most important new functions are: yaz_marc_create,
1664 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1665 decode and destroy respectively. Decoder can produce formats
1666 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1667 include/yaz/marcdisp.h.
1669 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1670 to UTF-8, UCS-32, wchar_t or Latin-1.
1672 * Prototypes for yaz_iconv_-functions moved to separate header
1673 include/yaz/yaz-iconv.h.
1675 Make a few private functions 'static' in unix.c. This prevents
1676 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1678 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1679 are set when Init Response is received.
1681 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1682 but returns diagnostic set as well.
1684 New function yaz_strerror which is a portable wrapper for
1685 strerror/strerror_r/GetLastMessage.
1687 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1688 is returned for MARC. If type is "oai", then OAI MARC is returned.
1690 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1693 --- 1.9.2 2002/11/26
1695 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1697 Fix bad race conditions on SIGTERM and terminate gracefully in
1700 Move retrieval (data1) module to Zebra since nobody seems to be
1703 Add GRS-1 render for ZOOM using same format as yaz-client.
1705 --- 1.9.1 2002/10/05
1707 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1709 Fix broken ESpec handling in data1 module.
1711 SGML reader parses comments and makes them part of the data1 tree.
1713 Added several type casts so that YAZ compiles as C++ code.
1715 ZOOM didn't handle PDU encoding failures properly.
1717 Added more Bib-1 diagnostics (approved extensions).
1719 GNU configure: better check for iconv.
1721 More portable use of accept, getpeername. Check for socklen_t. Use
1722 int/size_t if socklen_t is not defined.
1726 PQF parser rejects bad queries - including those with extra
1727 characters in them. PQF parser used to silently ignore that.
1728 Cleaner API for PQF added, which allows you to get detailed
1729 error information for bad queries (see yaz/pquery.h).
1731 Fixed bug in ZOOM_record_get for type "database".
1733 Implemented mini iconv library supporting conversions between
1734 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1736 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1738 --- 1.8.9 2002/08/20
1740 Fixed ZOOM C record cache so that preferredRecordSyntax and
1741 elementSetName is used to check for already fetched records.
1743 --- 1.8.8 2002/08/02
1745 Added three members in bend_initrequest structure to facilitate
1746 character set negotiation.
1748 Fixed a bug in frontend server that could cause indefinite
1749 loops under rare conditions.
1751 Revised character set utilities (charneg.h) so that encoding
1752 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1754 For PQF, directive @term <type> sets term type for Scan/Search.
1755 Here <type> is general, string, numeric, null. The term type
1756 is inherited - just like @attr.
1758 New call odr_set_charset that sets character set conversion for
1759 international-strings on a ODR stream. Prototype is:
1760 int odr_set_charset(ODR o, const char *to, const char *from);
1761 The InternationalString is still represented as C string in YAZ
1762 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1763 won't). On the protocol level, you can use any encoding.
1765 Support for UNIX sockets in ZOOM.
1767 Solaris recv sometimes returns errno == ENOENT. It is treated as
1768 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1770 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1771 both client and server. Code by Morten Bogeskov.
1773 --- 1.8.7 2002/05/22
1775 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1776 that they can be used directly from Visual Basic. You must recompile
1777 your windows APP if you're using ZOOM.
1779 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1780 Commands "lang" and "charset" sets language and character set respectively.
1781 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1782 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1784 Attributes from multiple CCL fields may be OR'ed rather than merged
1785 using directive "@field or". Fields are still merged by default -
1786 equivalent to "@field merge".
1788 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1791 Fixed bug in zget for parameter ExtendedServicesResponse.
1795 --- 1.8.6 2002/03/25
1797 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1799 Client displays USR.1:SearchResult-1 (hits per term).
1801 Additional Search Info for search in Generic Frontend Server.
1803 Fixed CCL parsing of "field=s".
1805 WIN32 installer - using the excellent NSIS software from nullsoft.
1807 Fixed CCL parsing of "field = - <number>".
1809 Added function yaz_marc_decode that decodes MARC for line mode
1810 display or XML (similar to that used by JZKit).
1812 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1813 Z39.50. But ISO/ILL was, however.
1815 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1816 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1818 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1819 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1821 --- 1.8.5 2002/02/03
1823 New YAZ client features: Command completion and new commands:
1824 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1825 Code provided by Jacob Poulsen.
1827 New call oid_trav, that visits all registered OIDs via callback.
1829 Function ZOOM_record_get now returns const char pointer rather than
1830 void pointer. It saves a lot of type casts.
1832 For YAZ client, command "auth" now allows you to set authentication
1833 in IdPass style. It is enabled when three tokens are given - order
1834 is user, group and password.
1836 Fix memory leaks in MARC record handling for ZOOM.
1838 New option for YAZ client, -k <kilobytes> that sets
1839 maximum record size. Similar to -k option for generic frontend
1840 server and yaz-ztest.
1842 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1844 Prefix query parser reports "fail" when bad attribute set is given.
1846 Fix in MARC decoder. Proximity logging. Fix for attribute set
1847 in scan handler for server. Patches by Shigeru Ishida.
1849 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1852 Configure option --with-openssl=<dir> now works when a directory is
1853 specified. Patch provided by Morten Bogeskov.
1855 New option for YAZ client, -u <auth>, that sets authentication.
1857 ZOOM fix: error information was sometimes "missing", since error
1858 was cleared/reset too when it shouldn't.
1860 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1862 --- 1.8.4 2002/01/04
1864 Scan for ZOOM API. New object ZOOM_scanset. New functions
1865 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1866 ZOOM_scanset_destroy.
1868 New ZOOM function, ZOOM_connection_last_event, that returns type
1869 of last event (such as "receive data", "send data", "apdu received",
1872 New ZOOM option, schema, that specifies schema for retrieval.
1874 New CCL feature. Qualifiers can be aliases for one or more
1875 other qualifiers (if more than one is given, OR is used).
1877 ZOOM uses named result sets if target supports it.
1879 Two new YAZ client commands: . (dot, which sources a script of YAZ
1880 client commands), and ! (to execute shell command.). Implemented
1883 Working on Debian packages.
1885 --- 1.8.3 2001/11/19
1887 YAZ client enables named result sets only if target supports it.
1889 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1891 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1892 with key="host" to get same result.
1894 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1895 Function Z3950_resultset_record(s) returns references to records
1896 "owned" by resultset. To become owner use Z3950_record_clone.
1898 Function z_ext_record handles Extended Services. Thanks to
1901 --- 1.8.2 2001/11/12
1903 CCL Parser fix: ignore token comma when dealing with and-lists.
1905 Documentation updates for COMSTACK.
1907 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1908 Changed prototype Z3950_records. For some functions, int parameters
1909 were changed to size_t.
1911 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1914 New MARC decode/display function, marc_display_exl, which properly rejects
1915 non-ISO2709 records. YAZ client uses it.
1917 --- 1.8.1 2001/10/29
1919 Fix bug: local attribute set wasn't set correctly in PQF strings.
1923 * Old Z39.50 codecs no longer supported.
1925 Added ZOOM C binding. See http://zoom.z3950.org/
1927 Renamed states for COMSTACKs to avoid confusion with events.
1929 Implemented cs_look and proper cs_rcvconnect.
1931 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1933 Configure detects POSIX threads on OpenBSD.
1935 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1936 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1938 When error is returned from present handler, non-surrogate diagnostic
1939 is returned in present response (and fetch handler is no longer called).
1941 * Minor adjustments to pquery parser (PQF). Token characters may be
1942 escaped by using backslash (C-style).
1944 PQF parser allows string attribute values to be specified. For @attr,
1945 non-numeric characters after the equal-sign are treated as strings
1946 (e.g. @attr 9=title).
1948 CCL trunction character may be defined (@truncation in file)
1950 * function zget_ExtendedServicesRequest sets waitAction to
1951 waitIfPossible (was wait).
1953 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1956 CCL operator names may be set in field definition files (CCL_bibset).
1957 See ccl/bib1 for an example.
1959 Fixes in ASN.1 compiler for C++ compatibility.
1961 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1962 and "op_or" to avoid conflict with C++.
1964 Fixed problem with GNU readline detection on Redhat 7.0.
1966 Added step-size for Scan backend handler.
1968 Fixed bug that made the frontend server crash when no attribute
1969 set was specified for scan.
1971 Front-end server automatically switches to original working directory
1972 when installed as an NT service. Previously -w had to be specified to
1975 Added extended attributes for retrieval module (data1), so that data1
1976 records carry d1_readXML/SGML attributes. d1_read also supports
1977 null-data rules ( <tag/>)
1979 On UNIX when POSIX threads are available, a separate library libyazthread
1980 is created. Programmers should link with that library and the yaz library
1981 when using threads. The reason for the split was that some applications
1982 on Linux, such as Apache, doesn't work well when using shared objects that
1985 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1986 (or any frontend server) in SSL mode by specifying ssl: followed by
1987 address. Only tested on UNIX.
1989 Added feature for CCL module. Virtual structure s=al or s=ol generates
1990 and-list and or-list respectively instead of phrase search.
1994 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1995 log_mask_str. This was done to avoid name conflicts with other libraries
1996 (such as other PHP extensions).
1998 Added raw OID member for preferred record syntax (request_format_raw)
1999 and returned record syntax (output_format_raw) for backend fetch method.
2001 Config file yaz-config now accepts options so that it returns specific
2002 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2004 Shared library support for UNIX using GNU libtool.
2006 * Modified backend interface. Request/Response struct's replaced by
2007 one read/write C struct. For example bend_fetchrequest and
2008 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2009 Every handler - even search has to be registered in bend_init
2010 handler. This means that the YAZ library no longer refers to
2011 external functions and it makes it possible to make the whole
2012 thing a single DLL/SO.
2014 Added Segment handler for backend server.
2016 Added Zmbol/Zebra administrative functions to YAZ client.
2018 Threaded frontend server on UNIX (when POSIX Threads are available).
2019 Starting the server with option -T enables multi-threading.
2023 Added configure option --enable-comp/disable-comp to control use
2024 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2025 located in sub directory asn.
2027 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2028 in ${exec_prefix}/bin along with the other programs yaz-client and
2031 GNU automake used to maintain makefiles.
2033 Added several OID's.
2035 Changed retrieval module so that we can load records with no abstract
2036 syntax defined. Tagpaths in these records are fully composed of string
2039 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2043 On UNIX, the generated makefile now supports a proper 'make install'.
2044 The prefix can be set via GNU configure to set the install location
2045 (default is /usr/local).
2047 * YAZ programs client and ztest were renamed to yaz-client and
2048 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2049 locations, such as /usr/bin,/usr/local/bin,etc.
2051 * YAZ Header files were moved from include to include/yaz. YAZ Header
2052 files are referred to as include <yaz/log.h> rather than <log.h>.
2053 The YAZ include path (-I ..) is therefore the same as before. Programmers
2054 should update their #include statements or use -Ipath/include/yaz
2055 instead. The main motivation for doing this change is that YAZ header files
2056 can be installed in "standard" locations /usr/include,/usr/local/include
2057 without introducing conflicts, since ALL YAZ header files are stored
2058 in subdirectory yaz (under /usr/include for example).
2060 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2061 rather than project/workspace files. We switched because project files
2062 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2065 Changed name of logging function, logf, to yaz_log, to prevent name
2066 clash with some math-log functions. The YAZ header log.h defines logf
2067 to yaz_log (#define) so there should be no incompatibilities by this
2070 Added bend_start/bend_stop handlers for server. These handler are
2071 called on start/stop of server. For windows they are called whenever
2072 a service is started/stopped.
2074 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2075 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2076 in util/yc.tcl. The auto-generated C code structures are, in a few
2077 cases, incompatible with the old decoders. There are differences in the
2078 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2079 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2080 The preprocessor variable ASN_COMPILED is defined when the compiled
2081 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2082 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2083 wish to use the old encoders/decoders you can specify --disable-yc
2086 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2087 version so that it supports both new - and old version of DB Update
2089 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2090 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2091 change. The name parameter can be set to 0 in which no name is specified
2092 for the construction. The macros odr_implicit and odr_explicit sets name
2093 parameter to zero for the construction involved. New macros
2094 odr_implicit_tag and odr_explicit_tag are similar to the others,
2095 except that a name parameter is added. For programmers' that don't use
2096 ODR they probably only need to change the call to z_APDU and z_External.
2098 Added access control facility by interfacing the TCP wrapper library.
2099 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2100 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2101 name of the daemon and enables the access control as specified in
2102 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2104 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2105 den Dool <H.M.vdnDool@kub.nl>.
2107 Added reference ID parameter to most functions in server API - refer
2108 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2110 Changed name of ccl library to libccl.a (was ccl.a).
2112 Fixed bug in decoder for Explain (Category TargetInfo).
2114 Added support for GNU readline in client. Thanks to Jacob Poulsen
2115 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2117 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2118 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2119 IMPLEMENTATION! This change was made to the development version before
2120 the ZIG decided to retract the amendment. If any users MUST be
2121 compatible with the original Update definition, PLEASE CONTACT US, and
2122 we will include a separate definition corresponding to the old Update
2123 ES. Note that because of the change to the ASN.1 of the
2124 TaskPackageRecordStructure we cannot define a single structure that
2125 will support both versions.
2127 * Added const modifier to buffer parameter for some ODR/BER encoding
2128 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2129 completeWAIS, odr_dumpBER.
2131 Fixed bug in client.c which caused a crash when a scanResponse didn't
2132 contain positionOfTerm.
2134 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2135 * will cause an error in a client if a non-YAZ target sends both a
2136 * list of Scan entries and non-surrogate diagnostics.
2138 Retrieval module enhancements. Tag sets may be typed in the reference
2139 to it. From the .abs-file the "tagset" directive takes a third optional
2140 integer type for the tag set referenced. From a .tag-file the "include"
2141 directive takes a third optional type as well. The old "type" directive
2142 in the tag set itself is still recognized but acts as the default type
2145 Backend interface change. Individual Scan terms returned from bend_scan
2146 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2147 in include/backend.h.
2149 Retrieval module enhancements. Multiple tag sets and attribute sets may
2150 be specified in abstract syntax specs. Revised the error/warning for
2151 logging messages reported by the retrieval module when reading the
2154 Object Identifier system (oid_..) changed. The API is backwards
2155 compatible but the oid-routines now allocates new OID's when needed.
2156 Raw OID's may be specified in oid_getvalbyname.
2158 YAZ now uses GNU configure to generate Makefile(s).
2160 * Minor changes in some of the member names of DeleteResultSetRequest and
2161 DeleteResultSetResponse. See include/proto.h.
2163 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2164 and added member 'languages' in TargetInfo (which was missing).
2166 Changed the way attribute sets are handled in the retrieval
2167 module. These are now cached, just like the abstract syntaxes
2170 Changed YAZ so that it links with compiled ASN.1.
2172 Added Explain-schema definitions and mapping routines. The following
2173 Explain categories have been implemented: AttributeDetails,
2174 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2176 Fixed minor bug in Windows version of Server Library.
2178 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2180 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2182 Added EXTERNAL: UNIverse Resource Report (non-standard).
2184 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2185 ENUMERATED and SET OF.
2187 * Added 'const' to some of the char pointer arguments for the
2188 functions, data1_read_node, data1_getelementbytagname,
2189 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2192 Fixed bug in data1_insert_taggeddata - the last_child member of
2193 parent wasn't initialised.
2195 * Changed data1_read_record and data1_read_node so that the supplied
2196 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2197 doesn't refer to any parts of the "SGML"-buffer.
2199 Fixed bug in server library (Windows version of statserv_remove).
2201 * Changed code so that it compiles as C++. The type definition
2202 of Odr_fun which is a member of Odr_arm was changed. The result is,
2203 that an explicit typecast is needed for the fun pointer when
2204 using Odr_arm - as in:
2205 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2207 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2209 Implemented the new structured date and time definition as approved
2210 by the ZIG. Added schemaId element to the specificTag in Espec-1
2211 (also approved at the last ZIG). Thanks to RVDM.
2213 Added some Object identifiers (RVDM).
2215 Changed the Update Extended Service (RVDM).
2217 Added command "refid" to client which specifies referenceId for
2218 the following requests.
2220 Implemented extended service handling for server. See ztest.c
2221 for an example as well as backend.h. New handlers are registerd
2222 in the Init handler.
2224 * Changed interface for sort in server.
2226 Added new members to statserv_options_block. It allows a server
2227 to read options from another source than just the command line. Thanks
2228 to Charles Woodfield.
2230 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2231 renamed to zboolean. Some C++ compilers complained about the name.
2233 Minor changes to gils.abs. Added index 's' (sort) on title
2234 and date/time-last-modified.
2236 --- 1.4pl2 1998/1/30
2238 Fixed bug in server library regarding inetd mode (-i). This bug
2239 was introduced by release 1.4.
2241 --- 1.4pl1 1998/1/29
2243 Added sort facility in client and backend server interface.
2245 Fixed problem with dependencies in Makefile(s).
2247 Fixed bugs for encoders/decoders of extended services and
2250 Implemented sub-tree feature for schemas. Sub-trees are
2251 referenced in *.abs-files. See explain.abs for an example
2252 of the use of this feature.
2254 Modified bib1.att; local attributes for ANY didn't include
2255 ANY itself (only affects use of the retrieval module).
2257 Fixed bug in plain SGML reader in function data1_read_node:
2258 tags with prefix "var" was incorrectly interpreted as variants.
2260 Added feature "sub-schemas" to enable references to - and definitions
2261 of - group of elements.
2263 * Removed member parent from type data1_element (in data1.h).
2265 Implemented function odr_nullval() that returns the value of
2268 * Removed member num_children from data1_node (in data1.h).
2270 Made NT service interface part of the server library. The
2271 function statserv_main uses the NT service when required and
2272 calls the statserv_start / statserv_close routines.
2274 Routine zget_SearchRequest and zget_PresentRequest fills
2275 resultSetName/Id member with "default" instead of "Default".
2277 Fixed memory leak in server. Request queue member wasn't freed.
2279 Fixed nmem_exit so that memory is freed.
2283 Revised the CCL parser utility to be thread safe.
2285 Added function, oid_ent_to_oid, to replace the function
2286 oid_getoidbyent, which is not thread safe.
2288 * Added nmem_init and nmem_exit to initialize and release
2289 NMEM resources. Function nmem_init should be called once in the
2290 initial thread before NMEM/ODR is used. statserv.c and client.c
2291 have been changed accordingly. The change was necessary to make
2292 NMEM thread safe. The NMEM memory pool is shared amongst threads
2293 in a process. Unix-based applications will still work fine without
2296 Added NT Services interface for the the Z39.50 (statserv) Server.
2297 Refer to the ztest.c source on the usage.
2299 Windows 95/NT port using MSVC5.0. Project files are included in the
2302 * Defined new 'global' handle for the retrieval (data1) system. The
2303 new handled, data1_handle, describes the state of the data1 system.
2304 This handle is passed as first argument to virtually all
2305 data1 related routines. The functions data1_create and data1_destroy
2306 creates and destroys a data1 handle respectively.
2308 Added ODR encode stream member to all backend request structures
2309 init, search, scan etc. This stream should be used to allocate all
2310 memory used for the response when thread safe operation is needed.
2312 Changed the comstack utility, cs_addstr, to be thread safe. The
2313 returned hostname string returned by the function is now part the
2316 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2317 function. The cs_straddr takes a COMSTACK handle as argument, so this
2318 function must be used after cs_create and before bind/connect.
2319 This function is thread safe.
2321 Moved test server to 'ztest' directory - generic server code still
2322 in 'server' directory.
2324 Made prefix query (pquery.c) utility thread safe.
2326 Added new function modifier YAZ_EXPORT to 'export' public DLL
2327 functions when using windows (see include/yconfig.h).
2329 Added definitions to the OID database (util/oid.c) (RVDM).
2331 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2333 Added call to ccl_rpn_delete in client program.
2335 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2336 release of RPN structure.
2338 Added support for C++, headers uses extern "C" for public definitions.
2339 With input from RVDM.
2341 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2342 Thanks to Ronald van der Meer (RVDM).
2344 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2346 Added support for private extensions to the OID database
2347 (oid_setprivateoids()). Thanks to RVDM.
2349 Added optional, physical ANY (key replication)
2351 Fixed null-reference problem in GRS-1 output filter.
2353 Proximity operator added to Prefix Query Format (PQF).
2355 In test client command "base" accepts multiple databases.
2357 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2361 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2363 Smallish bug-fixes in the new encoders/decoders (explain).
2365 Bug fixed in DeleteRequest.
2367 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2369 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2371 Added SOIF syntax (using private OID for now) to retrieval module and client.
2373 Added Update extended service.
2375 Added SearchResult-1 additional info structure.
2377 Added optional CCL (ISO8777) interpreter as separate module. Available
2380 --- 1.2 1996/6/10 (1st anniversary release)
2382 Added Summary record syntax. Lightly tested.
2384 Added OPAC record syntax. Untested.
2386 Added ResourceReport service encoders/decoders. Untested.
2388 Fixed bug in z_Unit - wrong tagging on unitSystem.
2390 Fixed bug in the DiagRecs decoder.
2392 Added options for max PDU size and session timeout to frontend-server.
2394 Added documentation of query-language parsers and other supporting utilities.
2396 [frontend-server] Added Attribute set to the bend_scanrequest API.
2398 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2399 surrogate diagnostics were generated.
2401 [retrieval] Allow multiple local values for attribute.
2403 [retrieval] Allow multiple attributes per element in .abs files. index type.
2405 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2407 --- 1.1pl2 1996/4/10
2409 Minor changes, mostly specific to Zebra's requirements (retrieval)
2413 Repaired bug in frontend server when running multiple listening
2414 endpoints in dynamic mode.
2416 z_External() now won't break if a known, ASN.1 value comes encapsulated
2417 in an octet-string. The value will pass through unmodified in an Odr_oct.
2419 Added a bit of code to the demo client to decode & display
2420 ASN.1-structured records represented in the octet-aligned branch of
2421 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2423 Added z_ext_getentbyref() to the ASN module. Doc updated.
2425 * Completed the SCAN definition in the ASN module. This may break SCAN
2426 code based on older YAZ-versions at compile-time. The fix is easy -
2429 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2430 under the SCAN definition. Remember to initialize this, server-people.
2432 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2433 that this does not extend to ODR and ASN.
2435 Comstack allows insertion of established socket (primarily for
2436 inetd-operation of servers). Doc updated.
2438 Front-end server can now start from the inetd in TCP mode. Doc
2441 --- 1.0pl4 1996/1/24
2445 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2446 the rank and record number.
2448 Adjustments to the frontend server.
2450 Fixed diagnostic BER dumper. It ignored the file argument.
2454 Various changes to retrieval module.
2456 Changed the union discriminators of the protocol files from enums to
2457 ints paired with #defines.
2459 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2462 *Changed operator in the RPN structure to 'roperator', again to avoid a
2465 Fixed problems in Explain decoders/encoders.
2467 --- 1.0pl2 1995/12/6
2469 Memory bug in log module fixed.
2471 --- 1.0pl1 1995/12/5
2473 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2475 Bug in Explain DatabaseInfo module fixed.
2477 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2481 The shift to v1.0 signals that we now consider the *core* functionality
2482 of YAZ reasonably stable (the core being more or less equivalent to
2483 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2484 tested (Explain not at all - though that will happen soonish).
2486 Minor changes to code to support Windows port.
2488 Various minor changes after we're getting to use GRS-1 & co. more.
2490 Added Espec-1 format.
2492 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2493 of the protocol and it cannot be selected when encoding (maps into 'string'
2494 when decoding). Needed to talk to some servers.
2496 Demo client can request simple element set names.
2498 Added Diagnostic Format encoders/decoders.
2500 Added simple Close handling to frontend server (no hooks for resource
2501 reporting yet), and demonstration client.
2503 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2505 --- 1.0b3 1995/08/24
2507 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2508 handled incorrectly when records were requested in the searchResponse. This
2509 will only affect you if you use the frontend-server.
2511 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2512 Test-client will ask for and print GRS1. Ztest will return dummy records
2515 Added Explain encoders/decoders to the service-level API. Untested.
2517 Added Extended Services: Item Order encoders and decoders to the Service-
2518 level API. Untested. We could use a recent copy of the pertinent bits
2519 of the ILL protocol to add those bits.
2521 Added diagnostic format 1 encoders/decoders to the service-level API.
2524 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2525 odr_cons.c, which causes a more correct output.
2527 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2528 was always set to 0 when no records were requested in the searchRequest.
2530 * Added better external-handling. This shouldn't harm old code that
2531 *encodes* externals. It can break code that looks for a
2532 'single-ASN1-type' representation, since those types that are known
2533 are now decoded immediately. Look at the SUTRS sample code in
2534 seshigh.c and client.c. Documentation updated.
2536 Handling of structured records in bend_fetchresponse. Length -1 marks
2537 structured record, type is deduced from format field.
2539 --- 1.0b2 1995/06/27
2540 Fairly quick maintenance release to add SUTRS support.
2542 Fixed handling of SUTRS records in the demonstration client.
2544 * Added format field to the bend_fetchrequest and bend_fetchresponce
2545 structures of the backend API (frontend server). When the record is
2546 returned, the value of the format field is mapped to an OID. The
2547 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2548 of the record. The special value VAL_NONE in the bend_request means
2549 that no specific format was requested by the client. Documentation
2550 updated accordingly. Test server (ztest) will return a fixed dummy
2551 SUTRS record if your client requests SUTRS.
2553 Documentation updated accordingly.
2555 You can now set external libraries and RANLIB support in the top-level
2559 First public release.
