3 CCL fixes: bug 2895 and bug 3539.
5 GR1-display: add comma in display - was removed by mistake in
8 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
10 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
14 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
15 result set from a connection. The result set will be on its own
16 thereafter; no operations on it will perform retrievals from a target.
17 Only cached copies are returned.
19 ZOOM C:fix case for HTTP servers responding with Connection:close.
20 Ensure that if there is a current task it is resumed (like fetching
21 more records in a result set) . Bug #3484.
23 PQF parser: use odr_atoi for Odr_int (not atoi)
25 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
26 values that contain any non-digits are treated as string attributes
27 (previously decoding only checked for leading character ([0-9]). PQF
28 encoding: attribute string values are not surrounded by double-quotes.
32 New utility for managing threads - thread_create.h.
34 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
35 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
36 but YAZ' implementation do.
38 Fixes for yaz_cond-functions on Windows 7.
40 DLL export more symbols.
42 zoomsh: show record do NOT render opac.
44 Remove *.la files from Debian and RPM packages.
48 Debian package libyaz-dev depends on libgnutls-dev again (was
49 removed in YAZ 4.0.6, but due to Libtool it is still needed
50 even though yaz-config do not list libgnutls libs).
52 ZOOM: Use only one WRBUF for returning string results for
53 ZOOM_resultset. Reduces memory usage for ZOOM in general.
55 ZOOM: ZOOM_connection do not use a shared pointer to
56 ZOOM_resultset after ZOOM_resultset is destructed by
57 user. Reverts to YAZ 4.0.4 behavior.
61 record-conv: fix problem with at least one XSL conversion -
62 due to probably incorrect usage of XML XSL documents.
66 Fix yaz-config for static mode and the use of SSL (gnutls).
70 Forward decl timeval struct in mutex.h and gettimeofday.h.
72 yaz-config: fix 'static' mode linking.
76 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
77 are wrappers for pthreads or Windows. For Windows these are put in
78 a separate DLL: yaz_cond4.
80 libyaz.la (whole source) is compiled with thread. If thread support
81 is enabled enabled, all source of YAZ is compiled with treading support.
82 This allows core utilities such as yaz_log to use thread facilities.
83 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
84 thread utilities. This commit moves mutex utilities (mutex.c) from
85 libyaz_server.la to libyaz.la.
87 yaz-json-parse displays leading text until error.
91 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
92 patch from Giannis Kosmas.
94 SRU: no longer URL encode SRU database. The URL for an SRU server is
95 a URL and such is alreeady encoded - at least when given with leading
96 http:// or https://. This reverts behavior to YAZ 3.0.50.
98 Support for new MARC XML notation TurboMARC which like MARCXML is a
99 complete representation of MARC/ISO2709.. This one, however, is more
100 compact and allows for faster processing with XSLT. TurboMARC can be
101 used in the marcdisp.h API, from the yaz-marcdump utility and from
104 yaz-ztest can be configured - via the database - to perform certain
105 delays when it performs operations search, present and single record
106 fetch. This allows testers to make yaz-ztest act as a real or even slow
107 Z39.50 server. Refer to the yaz-ztest man pages for details.
111 wrbuf_destroy allows NULL WRBUF passed to it.
113 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
115 Add ZOOM_connection_close.
117 No fixed size buffers for ZOOM shell - bug #3257.
119 tstodr: make it work on s390 platform.
121 New icu iterator-functions. The new icu_iter-functions makes it possible
122 to use ICU chains from many threads.
124 yaz-client: better syntax check for show command.
128 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
131 New simple local-file XML include facility which allows file glob-patterns.
132 Refer to yaz/xml_include.h.
134 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
137 ZOOM_record_get supports new parameter "format" which makes it format XML
140 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
141 JSONText in ECMA-262) is JSONValue, not JSONObject.
145 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
146 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
148 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
149 POSIX/Unix builds .so with major version 4.
151 Remove old LOG_-defines from log.h. They have been obsolete and
152 undefined by default for the last 5 years.
154 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
156 GFS: Remove socket (int *fd) from search_rr handler. The socket
157 descriptor ptr is a facility that allowed a search handler to supply
158 a socket which would serve as a callback - when search was complete.
159 This facility has now been in use for years.
161 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
162 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
163 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
164 returns 'const char *' rather than 'char *. The returned string is
165 read-only and should not be modified by applications. COMSTACK cs_close is
166 now a void function - it no longer returns int. No applications check for
167 the value and the implementations has always returned 0.
169 ZOOM: use size_t for scan hit counts and str size. Functions
170 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
171 occ (hit count) and len (string length) are now of type size_t pointer
172 rather than int pointer. This is to be able to represent large hit counts
173 and to also just to use the proper type for string length (strlen result).
175 New JSON parser. Refer to include/yaz/json.h .
177 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
178 Used to be int in some cases. Many wrbuf_-functions used to return an int
179 indicating some length.. These return values were never used. And so they
182 ODR: odr_malloc, odr_total now takes size_t for size.
184 clone_z_type: fix leak; occurred for encoding failures.
186 --- 3.0.52 2009/12/03
188 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
189 bug was introduced in 3.0.51.
191 --- 3.0.51 2009/12/02
193 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
195 tcpip comstack: fix leak for getaddrinfo.
197 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
198 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
199 Decoding of SRU "path" database is performed by private function
200 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
201 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
203 yaz-client: honor base command for SRU. Change when database setting
204 is applied for SRU and ensure it is kept when a connection is reset.
205 Change also the way errors are displayed or SRU (decoding of packages).
207 --- 3.0.50 2009/11/02
209 Add support for extra request / response data for SRU codecs and GFS.
210 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
211 for extra data response buffer and length. For the GFS, both request
212 and response data (XML) is carried in extra_args and extra_response_data
213 for the search handler. Patch by Ko van der Sloot.
215 ZOOM: For queries that cannot be converted to the specified rpnCharset,
216 ZOOM now returns a diagnostic on the client-side ('invalid query' /
217 10010). This fixes bug #2113.
219 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
220 cmdfile included a 'quit' command that would result in a memory violation.
222 --- 3.0.49 2009/10/01
224 Make a number of functions defined in xmlquery.c static. These have
225 never been declared in a public header file (yaz/xmlquery.h) and was
226 made public by mistake.
228 Improve speed of character conversions (iconv utilities). This makes
229 conversions from MARC-8 faster.
231 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
232 unless type desired is "raw". This will prevent type "xml" from
233 returning ISO2709 .. Which obviously can not be XML parsed.
235 Fix memory leak in ZOOM that would occur if option apdulog was used
236 on a re-used connection.
238 Frontend server logs HTTP requests.
240 Frontend server now sends Z39.50 close when it times out (sesssion has
241 been idle for too long). Versions 2.0.30 and earlier also sent close.
242 But due to a mistake this was disabled in all versions after that, i.e.
243 the server would just close the socket immediately.
245 yaz-client emits a better message when receiving an unrecognised
246 userInformationField.
248 Skip zero-length subfields when decoding ISO2709. This rare case happens
249 if a record has two FS characters in a sequence. Without this patch
250 there would be a reference beyond char array in using_code_len fragments
253 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
255 --- 3.0.48 2009/08/28
257 The show command offered by the zoomsh command now takes a 3d optional
258 parameter type which is what is passed to ZOOM_record. If the type
259 argument is omitted, "render" is used.
261 RPN to CQL conv may use USE string attributes (bug #2978).
263 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
265 --- 3.0.47 2009/07/08
267 Function yaz_xml2query allows a diagnostic element in the PQF XML
268 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
269 code and additional info respectively.
271 The BER BOOLEAN is now the integral type Odr_bool which still happens
272 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
273 typedef'd to Odr_int. This is still an integral 'int', but it may be
274 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
275 ASN-1 compiler as well as programs has been updated to use the new types.
277 --- 3.0.46 2009/06/08
279 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
280 only the bibliographic record was rendered. For type=opac, an OPAC
281 record is only returned if it is present.
283 iconv: small fix for encoding of advancegreek.
285 yaz-client: avoid double display of SRU/SRW records (bug #2798).
287 yaz-client: option auto_reconnect=on really reconnects.
289 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
291 server: avoid null ptr ref for for yaz_poll errors.
293 build: fix RPM build for RHEL 5.3.
295 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
297 --- 3.0.45 2009/03/31
299 Fixed bug #2709: TCP connect returns Invalid argument.
301 Fixed compilation for mingw.
303 Honor charset for raw records (ZOOM_record_get).
305 Fixed use of errno for threaded mode that was seen on Solaris 10.
307 Fixed argument passing with blanks in value for Windows Service.
309 Disable YAZ' own log rotate by default (no 1 GB limit).
310 The variable l_max_size which specifies the log file limit is set to 0
311 (DISABLED): This is due to the fact that YAZ is most often deployed using
312 logrotate. Also YAZ can not perform log rotate because of unsufficient
313 permissions (setuid).
315 --- 3.0.44 2009/02/17
317 List supported encodings in man page for yaz-iconv.
319 Fixed missing SSL libs for --libs output
321 Re-established OID record syntax application-xml. Nobody should use it
322 but we don't want to change soname because of this symbol being absent.
324 --- 3.0.42 2009/02/02
326 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
328 Added member named_result_sets for init handler struct for the GFS. This
329 allows a server to disable named result sets.
331 Removed OID record syntax application-xml.
333 Added support for rule-based transliterator for ICU wrapper of YAZ.
335 Fixed bug #1902: yaz-icu XML output.
337 Make YAZ checks Emacs friendly.
339 BITSTRING value shows value. Bug #2346.
341 ISO2709 decoding: skip control characters from indicator data.
343 Omit sort key by default in yaz-icu's output.
345 Allow combined single char options (again) for YAZ' options function.
347 Utility yaz-marcdump got option to display YAZ version (-V).
349 Allow YAZ to use ICU 3.4.
351 Added new ICU test case which illustrates removal of diacritics.
353 --- 3.0.41 2008/12/29
355 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
357 --- 3.0.40 2008/12/29
359 For configure, using option --without-xml2 also disables Libxslt/Libexslt
362 Fixed bug #2352: yaz-marcdump crashes for certain record.
364 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
366 Added support for Danmarc2 to UTF-8 conversion.
368 Added support for ISO5426 to UTF-8 conversion.
370 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
371 implementation version.
373 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
375 --- 3.0.38 2008/11/10
377 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
378 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
380 ZOOM C now interprets databaseName option for ZOOM connection as path
383 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
385 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
387 Dummy Libxml2 types no longer defined in headers of YAZ'.
389 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
392 --- 3.0.36 2008/09/26
394 Various ODR chapter fixes.
396 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
398 Added missing source for Windows compilation, mutex.c.
400 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
402 For SRU connections in ZOOM all records up to "count" are now fetched.
404 Fixed crash in generic frontend server (and yaz-ztest) which occurred
405 in Windows due to bad error handling for Libxml2.
407 Added facility for sending arbitrary records (ASN.1 any) using
408 ZOOM C's Extended service update. Patch by Sam Reynolds.
410 New options for ZOOM C's connection, logapdu which makes ZOOM log
413 --- 3.0.34 2008/06/18
415 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
417 --- 3.0.32 2008/06/12
419 Fixed memory violation that could occur when decoding UTF-8. This bug
420 was only present in 3.0.30 of YAZ.
422 --- 3.0.30 2008/06/06
424 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
425 GNU TLS is used by default (if found).
427 yaz-ztest returns OPAC records if a client asks for OPAC.
429 Improved speed of MARC-8 encoding.
431 Added support for lossy and loss-less MARC-8 encoding.
433 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
435 Added new Windows Service wrapper (sc).
437 yaz-client's itemorder command may now send a file.
439 Fixed yaz-marcdump to allow the use of NS prefix for record element.
441 Added new function yaz_log_xml_errors.
443 Allow (but warn) unknown XML attributes in MARCXML parsing.
445 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
447 The UTF-8 to MARC-8 conversion now uses a different set of characters
448 for Greek symbols. Bug #2120.
450 --- 3.0.26 2008/02/21
452 Added yaz_daemon (daemon.h).
454 Fixed bug #2068: pkg-config trouble
456 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
458 --- 3.0.24 2008/01/28
460 Document --with-xml2 option.
462 Added OPAC XML XSD (etc/opacxml.xsd).
464 Allow glob mask for name attribute in retrieval element for the
465 generic frontend server's retrieval facility.
467 Changed yaz_poll_poll to return yaz_poll_except for all returned events
468 except POLLIN/POLLOUT.
470 Fixed error handling in cs_listen. Bug #2037.
472 --- 3.0.22 2008/01/20
474 Fixed version in yaz/yaz-version.h.
476 Fixed bug #2027: Crash when closing connection.
478 Changed configure so that ICU support is only enabled if only ICU
479 and Libxml2 is available (because the ICU chain is XML based).
481 --- 3.0.20 2008/01/15
483 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
484 is built. Only this DLL depends on the ICU runtime.
486 yaz-ziffy is no longer part of YAZ. It is distributed separately by
487 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
489 Changed license of CCL module to 'Revised BSD'. After consultation with
490 remaining members of the original EUROPAGATE consortium, we are re-issuing
491 the CCL module without a separate license. The software was developed by
492 Index Data as part of a research project. The special license was included
493 to help feed usage information back to the project consortium to support
494 project evaluation. At this time, the project consortium has long-since
495 disbanded, and the majority of the original principals have retired. At the
496 same time, we have significantly modified the software during the following
497 years, to the point where very practically no original code remains. To
498 simplify re-use of the software, we have contacted those members of the
499 consortium who could be reached, and agreed to re-issue the module as a
500 proper part of the YAZ package.
502 Tcl scripts uses /usr/bin/tclsh as preferred shell.
504 CQL closer to being version 1.2 compliant. CQL also allows free-form
505 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
508 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
509 bug could make Extended services handling crash in the ZOOM layer. This
510 bug was only present in YAZ 3.0.18.
512 --- 3.0.18 2007/12/19
514 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
517 yaz-marcdump reads and writes collection wrapped records.
519 Handle OPAC for record conversion module.
521 Fixes for ICU wrapper.
523 Allow ICU libs to be controlled with --with-icu .
525 --- 3.0.16 2007/11/12
527 Added yaz_poll which is a wrapper for select/poll. When poll is available
528 and non-buggy, it is used, by yaz_poll . This allows more than 1024
529 sockets to be in use.
531 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
532 functionality through an XML based configuration (ICU chain). This system
533 is useful for search facilities such as Pazpar2 and Zebra that needs to
534 perform tokenization of indexed material. The ICU code in a separate
535 library libyaz3_icu.a.
537 Added HTTP tunnel facility for COMSTACK, bug #1752.
538 This is a facility that allows a Web proxy, such as squid, to tunnel
539 Z39.50 traffic. This facility is "transparent" to must applications
540 using YAZ. It's enabled by using pseudo transport connect: followed by
541 the proxy address, followed by command, then follwed by he regular
542 "virtual" addresss. For example,
543 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
545 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
547 --- 3.0.14 2007/09/21
549 Fixed bad memory reference in ZOOM_record - cuased by member not being
550 initialized. This was a problem only in YAZ 3.0.12.
552 Fixed bug in conversion from MARC to XML: Non-XML characters in control
553 fields were not removed.
555 Changed the way C code is generated from codetables.xml. Made a MARC-8
556 conversion trie for each characterSet section rather than codeTable.
557 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
558 of codetables.xml from Larry Dixson, LOC. Bug #1464.
560 --- 3.0.12 2007/09/12
562 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
563 from ZOOM_record_error).
565 ZOOM C function ZOOM_record_get returns record schema for type="schema".
567 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
569 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
571 Better SRW-to-Bib-1 diagnostic mapping.
573 ZOOM C and yaz-client announces SRU version 1.2 by default.
575 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
578 Fixed in yaz_sru_decode to allow other version than 1.1.
580 --- 3.0.10 2007/08/22
582 Added support for SRU scan for ZOOM.
584 Added support for the use of the older versions or Extended Service
585 Update in ZOOM. To faciliate this, an option "updateVersion" may be
586 set to the version , 1=first, 2=second, 3=third. The third version is
587 what ZOOM C has used so far. And that, obviously, is the default.
589 Added support for CCL queries in Z39.50 queries sent to the GFS (and
590 therefore in Zebra and in SimpleServer-based applications). The new
591 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
592 qualifier file used to transform incoming CCL queries into Type-1 RPN,
593 which is passed into the back-end search callback function.
595 Added support for HTTP Basic authentication in clients: the SRU/W
596 codec encodes the username/password elements of the PDU structure
597 appropriately, and these may be set using the "user" and "password"
598 options in ZOOM-C applications (the same options that are used for
599 Z39.50 authentication).
603 Fixed bug #1208: SSL appears to be broken in ZOOM.
605 Fixed bug #1206: Libxml2 include path weirdness.
607 Added oid_name_to_dotstring.
609 Allow elementSetName to be specified for ZOOM C record update.
611 Allow waitAction to be specified for ZOOM C based for Extended Services.
613 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
614 syntax OID. Bug introduced in YAZ 3 series.
616 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
620 Fixed bug #1157: yaz-client does not read .yazclientrc from current
621 directory. yaz-client now reads commands from file given by option -f
622 if specified; then tries to read .yazclientrc in current directory.
623 Failing that, it reads .yazclientrc from user's home directory.
625 Added support for correlationInfo Note and ID for Record Update via
628 Added yaz-client command querycharset which specifies character set for
629 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
630 (termListAndStartPoint).
632 Charset ISO5428:1984 is an alias for ISO5428-1984.
634 Implemented a way to perform scan in a result set using Z39.50. This
635 is achieved by attaching the result set name in the characterInfo
636 (type InternationalString) of OtherInformation in the Scan Request PDU.
637 The result set is identified in the otherinformation by the new OID:
638 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
639 This allows for scan in result set and faceted search . Zebra did some
640 of this in the APT term using attribute type 8 and value being result
641 set. Using the OtherInformation approach for this is cleaner and easier
642 to work with in proxies and the like. This facility can be used in
643 yaz-client using new command setscan which takes a result set as first
644 argument, start position (APT) as second.
646 Changed decoding of SRU XML packed records to deal with servers that
647 have recordData with XML data with multiple root nodes. Also make
648 comparison for recordPacking case insensitive. Again, one server
649 returns "XML" where others return "xml".
651 For SRU responses allow Content-Type application/xml as well as text/xml.
655 Fixed bug in character set conversion of BER strings. Bug introduced
660 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
662 For OID class, use oid_class consistently.
664 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
667 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
668 character set for bibliographic information interchange". By Giannis Kosmas.
670 Added documentation on new OID API.
674 Changes to generic frontend server interface: added new member
675 'query_charset' for bend_initrequest structure. A backend init handler
676 should set this member to its native character set for query terms.
677 When defined, the frontend server logic will announce this character set
678 to a client if the negotiationModel bit is set by the client. All server
679 implementors are encouraged to specify this. If a backend server does not
680 specify this a warning is issued using yaz_log(YLOG_WARN,..).
682 Added CCL utility to remove terms (stop words) from resulting RPN
683 tree. This is handled by functions with prefix ccl_stop_words_ .
685 New ZOOM C option, "rpnCharset", which allows client-side conversion of
686 terms in RPN queries.
688 Clean-up the CCL API. Moved some internal structures from ccl.h to
689 private header cclp.h. Changed ccl_parser_create so that a Bibset must
690 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
691 This is replaced by ccl_parser_find_str which takes a string instead.
693 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
694 libyaz.la is the core of YAZ except the generic frontend server and
695 does not depend on POSIX threads anymore. libyaz_server.la is the
696 generic frontend server facilities and uses POSIX thread functionality
697 if available. The libyaz.la no longer depends on POSIX threads because
698 the number of global structures is limited. NMEM no longer re-uses blocks
699 between threads ; it simply free's memory immediately but allocates in
700 "large" chunks as usual. We don't expect any performance penalties
701 because of this. The yaz_log system is still using a global log_level so
702 caution must be taken when modifying it with yaz_log_init_.. +
703 yaz_log_mask_str. This, however, should not cause any trouble because
704 these functions are called during initialization of application code
705 anyway. `yaz-config --libs server` returns libs for server applications;
706 `yaz-config --libs` returns libs for non-server applications.
708 New OID database - with public definitions in oid_db.h. Removed old OID
709 database including the head oid.h and definitions such as enum oid_value
710 and struct oident. The new OID database uses the same string names as
711 before but the 'protocol' is gone. There are now only two representations
712 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
713 converts from string to OID; functions with prefix yaz_oid_to_string
714 converts the other way.
716 Change to emit_term() in CQL-to-PQF query translation: when a term has
717 the /regexp relation modifier, do not process it for leading and
718 trailing "^" and "*", which have quite different meanings in regular
721 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
722 write handlers no longer carries a 'last' parameter. This will make
723 yaz_iconv flush "less" characters. A flush is performed by call to
724 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
726 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
727 removed, because function yaz_query_to_wrbuf does the same.
729 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
730 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
732 Deprecated MARC utility functions removed.
734 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
737 Branch split: YAZ_2_1_55_branch
739 --- 2.1.54 2007/03/16
741 Fix to ZOOM-C so that transparent reconnection is properly handled on
742 connections that are in asynchronous mode.
744 Fixed compilation on OpenBSD 4.0.
746 Large strings in GRS-1 records are now properly displayed in yaz-client.
748 Added character conversion support for "advancegreek"; based on patch from
751 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
752 sequence is met. Before the error was not set so it would be unknown.
754 Adjust yaz-marcdump MARC reader so that it skips until record separator
757 --- 2.1.52 2007/03/07
759 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
760 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
761 fd_set structure used as a bitmask for the FDs to be selected on.
763 Using ACX_PTHREAD macro to check for POSIX threads.
765 Fixed have-vsnprintf check.
767 --- 2.1.50 2007/02/23
769 Fixes for configure on BSD. Bug #900.
771 Added snprintf/vsnprintf wrappers for systems that don't have
772 limits (heavens forbid).
774 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
775 created before all previous tasks were completed and removed from the
776 task queue, the new task could be removed by a mistake.
778 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
780 Implemented pass-through CQL-to-PQF conversions. Bug #861.
782 Fixed bug #832: Problem with MARC/charset in yaz-client.
784 Fixed bug #668: save command line history for yaz-client.
786 Fixed bug #830: pkg-config support.
788 --- 2.1.48 2007/01/23
790 Extended ZOOM result set options with two options that may be read by
791 a client: resultSetStatus and presentStatus with values as specified for
793 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
795 Fixed bug #827: Using SSL fails on Debian etch.
797 Fixed bug #826: Weird looking chars for set of MARC records.
799 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
800 that is treated as an ItemOrder with itemRequest being an XML document
801 external. The value of "doc" is the content.
803 Extended the GFS search facility. New member of bend_search_rr
804 'estimated_hit_count' signals that hits is known to be an estmate
805 (higher or lower than real hit count). New member 'partial_resultset'
806 signals that the search was partial (hit count is lower or equal than
807 real hit count). For Z39.50, the information is stored in resultSetStatus
808 member of SearchResponse APDU. For SRU, the information is signalled
809 via SRU diagnostic 59: "Result set created with valid partial results
812 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
814 --- 2.1.46 2007/01/13
816 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
818 Added ZOOM_connection_peek_event.
820 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
821 the following new functions:
822 ZOOM_event_nonblock, ZOOM_connection_process,
823 ZOOM_connection_get_{socket,mask,timeout},
824 ZOOM_connection_fire_event_{timeout,socket}.
825 The existing blocking event handler, ZOOM_event, is a wrapper for the
826 + blocking ZOOM_event_sys_{poll,select}.
828 Implemented function ccl_xml_config which parses XML version of CCL
829 configuration (bug #798).
831 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
833 Added timings utility (yaz/timing.h)
835 --- 2.1.44 2007/01/03
837 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
840 Fixed bug #779: Rotation of apdu.log fails.
842 Fixed for character set conversions:
843 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
844 Honor G1 set in MARC-8 decoding.
846 --- 2.1.42 2006/12/17
848 Fixed bug #775: char conversion does not handle Alternative UTF-8
851 Implemented function yaz_marc_read_line which parses MARC line format
852 records. There is a wealth of formats out there. So far, this function
853 reads line records produced by yaz_marc_write_line.
855 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
856 more generic and easier to remember(!) options: -i format and -o format
857 which specifies input format and output format respectively - where
858 format is one of "marc", "marcxml", "line", "marcxchange".
860 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
861 does not print anything except warnings for records.
863 For yaz-marcdump, added support for MARC split into files (-s) with a given
866 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
867 spec, at http://www.loc.gov/standards/sru/record-update/
868 This has changed the binary layout of the following structs:
869 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
870 bend_update_rr . Patch by Ko van der Sloot.
872 Added GFS utility function bend_assoc_is_alive which returns 1 if
873 association is still alive (client is connected); 0 otherwise (client
874 closed connection). This allows busy servers to stop working for
877 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
878 been a separate piece of software. This version of ziffy has been modified
879 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
881 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
883 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
884 Client code may now interrogate options such as "init_opt_sort" to
885 find out whether the server claims to support various options.
887 --- 2.1.40 2006/11/27
889 Added utilities yaz_{set,get}_esn to set/get element set name from
892 Removed the build of libyazthread.la. The libyaz.so is the threaded version
893 of YAZ and has been so since YAZ 2.1.10.
895 Implemented ZOOM_record_error which returns error information for
896 record (surrogate diagnostic).
898 --- 2.1.38 2006/10/31
900 Updates for SRU Update by Ko van der Sloot:
901 1. Changed name from "operation" to "action"
902 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
903 versions in the code, marked as 'backward compatible'.
904 3. Added diagnostics for SRU Update.
906 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
908 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
910 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
912 For GFS, fixed problem with SRU diagnostic 'First record position out of
913 range' being issued for 0 hits.
915 zoomtst10 part of Windows Build.
917 --- 2.1.36 2006/10/13
919 Implemented yaz_filepath_comp which splits a path into file path
920 components (required by Zebra 2.0.3+).
922 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
923 BSD inspired license until now so this should not have any real impact on
924 anybody. See http://www.opensource.org/licenses/bsd-license.php
926 Fixed bug #687: Missing log lines.
928 Fixed bug #678: CQL to PQF translation does not preserve double-quote
931 Fixed bug #689: SRU diagnostics to be added.
933 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
934 whether a connection is idle (no more work do do).
936 --- 2.1.34 2006/10/04
938 Change type of optval from long to int for invocation of setsockopt with
939 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
941 Added support for specifying the max log file size for the Generic
942 Frontend Server. The size is given with option -r.
944 --- 2.1.32 2006/09/21
946 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
948 --- 2.1.30 2006/09/17
950 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
953 Fixed bug in Generic Frontend Server that could cause a server to stop
954 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
956 For the generic frontend server, the maximum record size is used as maximum
957 size of incoming packages (SRU + Z39.50). The value until was previously
958 only used in Z39.50 Init negotiation and, later, in a session controlled
959 sizes of records returned. This is controlled using -k option. It can be
960 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
962 --- 2.1.28 2006/09/04
964 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
967 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
969 New option for yaz-marcdump -lpos=value which allows setting a portion
970 of MARC header to a certain value.
972 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
974 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
975 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
977 --- 2.1.26 2006/08/15
979 Fixed problem with SRU mode type (soap, get, post) for yaz-client
982 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
984 --- 2.1.24 2006/08/08
986 Fixed MARC ISO2709 encoding routines to deal with character set
989 Minor changes to GFS logging. Database included in search request log
992 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
993 cached/multiple records.
995 Shared libraries are built by default on Unix+configure.
997 Changed cql2pqf transformation to use a different evaluation order. The
998 new order is: always, relation, structure, position, truncation, index
999 and relationModifier. Old order was: always, relation, relationModifier,
1000 structure, index, position, truncation. Note that the the latter ones
1001 override former ones for identical attributes.. The new scheme means that
1002 it is possible to override any existing attribute with a relationModifier.
1003 And also that it is possible to override everything for the index rule
1004 (except the ones listed in relationModifier). No order is perfect but this
1005 one, we believe, covers more real cases.. The "always" should have been
1006 called "default", since the attributes there can be overridden with all
1009 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1010 compilation phase, but also for yaz-config --cflags output. This allows
1011 us to have public headers with Libxml2 stuff in them . It should also,
1012 eventually, make Libxml2 checks redundant in packages using YAZ, such
1015 --- 2.1.22 2006/06/15
1017 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1018 stored in uri, message and details.. Previously diagnostics were stored
1019 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1020 compatibility.. but he's probably the only one affected, so.
1022 Added support for CCL, compiled on the client side, in ZOOM-C. This
1023 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1024 input; the resulting query objects can be used for for searching with
1025 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1027 YAZ' configure searches for OpenSSL by default.
1029 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1030 SL_CTX_use_certificate_file. See
1031 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1032 for more info. Thanks to Ko van der Sloot.
1034 --- 2.1.20 2006/06/02
1036 Bug #600: SRU GET, POST support for yaz-client. Introduced
1037 command 'sru' which selects method SOAP/GET/POST.
1039 Allow missingValueAction to be specified for the sortspec string -
1040 function yaz_sort_spec. By default, the missing value action is null.
1041 Use ! to specify "abort". Use = followed by stringvalue to specify default
1044 Ensured that Present-handler (if defined) is called in GFS before any call to
1045 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1046 searchRetrieve requests.
1048 Documentation for YAZ is now based on the Docbook XML/XSLT using
1049 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1050 is no longer depending on jade/openjade or docbook-to-man scripts.
1051 PDF is no longer part of the distribution - but can optionally be
1052 made using DSSSL/jadetex or FOP.
1054 Added retrieval handling support in Generic Frontend Server to support
1055 conversion between MARC/XML as well as XSLTtransforms. See
1056 etc/yazgfs.xml for an example.
1058 Added Authentication support to Generic Frontend Server in SRU
1059 mode. Authentication using HTTP Basic is supported, as is the use
1060 of 'x-username' and 'x-password' parameters in the request itself.
1062 Added support for a new character set MARC8s identical to MARC8 except
1063 that it converts combined characters to single Unicode characters in the
1064 Latin-1 range (when possible).
1066 --- 2.1.18 2006/04/24
1068 ASN.1 compiler 0.4: generates brief Doxygen file header for
1069 generated .h/.c files.
1071 Utility yaz_iconv now supports conversion to MARC-8.
1073 New facilities for the MARC module. The reading - and writing of
1074 content are separate methods for the yaz_marc_t handle. The following
1075 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1076 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1077 format). Write functions have prefix yaz_marc_write_.. The existing
1078 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1079 available. Removed support for OAI-MARC and simplexml (not the
1080 simplexml from PHP5).
1082 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1083 to be returned for this connection.
1085 --- 2.1.16 2006/03/31
1087 Allow multiple languages and charsets to be specified with
1088 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1089 negcharset iso-8859-1,utf-8
1091 Translation of proximity nodes from CQL into PQF now works.
1093 Moved to automake 1.8, 1.9.
1095 Added function yaz_log_set_handler which allows a log handler to be
1096 installed. This handler will be called for all log messages. Output
1097 to file is also produced; but that can be disabled by passing NULL
1098 fname to yaz_log_init_file.
1100 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1102 For SRW (including GFS), accept application/soap+xml as content-type
1105 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1106 produces NO stylesheet reference even if a default stylesheet is specified
1109 --- 2.1.14 2006/03/14
1111 Updated Windows package to include yazd.dll + yazd.lib for the
1112 Development component.
1114 If the environment variable YAZ_LOG is set, then it is used as a
1115 string indicating the default level of logging to use if not
1116 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1117 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1118 used as before. So, for example, to omit warnings from YAZ logging,
1119 export YAZ_LOG=-warn
1121 cql_transform() now map structure and other attributes before indexes,
1122 so that index-specific structures and other attributes can override
1123 defaults. So now a combination of mapping specifications such as:
1125 index.dc.date = 1=date-modified 4=5
1126 does the right thing.
1128 cql_transform() now also respects the "always" mapping specification,
1129 which establishes an initial set of attributes to be used for all
1130 terms except where overridden by more specific attributes associated
1131 with the index, relation or modifier.
1133 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1134 which mode to use; one of "post", "get" or "soap" (SRW, default).
1136 Fixes for yaz_iconv routines: changed trie-based character set conversions
1137 to use only non-negative values for bit fields due to Sun's C compiler not
1138 supporting negative values.
1140 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1141 sequences where not read correctly. Fix by Rustam Usmanov.
1143 Updated win/makefile to use options, settings which makes things
1144 compile with VS C 2005.
1146 --- 2.1.12 2006/02/01
1148 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1150 In ZOOM socket code, use select instead of poll on MacOSX.
1152 ZOOM-C now support client-side compilation of CQL into RPN that is
1153 sent to the server, enabling CQL to be used against all Z39.50
1154 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1155 ZOOM_query object, and submit it using ZOOM_connection_search().
1156 The CQL-to-RPN translation uses a configuration file, the name of
1157 which must be specified in the Connection's "cqlfile" option.
1159 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1160 function, which takes as its start-term parameter a ZOOM_query object
1161 (which may have had either CQL or RPN set into it).
1164 --- 2.1.10 2005/11/29
1166 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1167 GFS to support this as well. Backend handler, bend_srw_update, does the
1168 update work. Code contributed by Ko van der Sloot.
1170 Allow retrieval of Search Result-1 information in ZOOM by the use of
1171 options that are attached to a result set. ZOOM documentation updated
1174 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1175 UTF-8 conversion. Patch by Raj Patel.
1177 Added option -m to GFS to control formatting of timestamps in log file.
1179 Added 'exit' as synonym for 'quit' in yaz-client
1181 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1182 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1183 for the new members. Patch by Ko van der Sloot.
1185 Added support for SRU POST. It is supported for content-type
1186 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1188 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1189 Instead make the library libyaz.la multi-threaded. Threading as a whole
1190 can still be disabled by configure option --disable-threads. Previosly,
1191 with older GLIBCs there were problems with MT libs under Apache. This
1192 has now been fixed a long time ago.
1194 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1197 CQL module modified to be case insensitive for relations/indexes/operations.
1199 Fixed bug in CQL transform code: incorrect value relationModifieder
1202 Added 'show all' command for yaz-client which retrieves all results
1205 Added new yaz-client, xmles, which takes a (private) OID and
1206 a document to be sent as an extended service request.
1208 Describe new yaz-client commands wait_response and set_auto_wait.
1210 Increase TCP/IP listener backlog from 3 (which I am guessing was
1211 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1212 that the socket will queue as many incoming connections as it's able
1213 to handle ongoing connections. In other words, it will never now
1214 refuse a connection that it would be able to handle merely because
1215 it's not got around to accepting() enough of the pending connections
1216 yet. This is the behaviour anyway under Linux, where the listen()
1217 argument is ignored; but not under BSD and on systems such as
1218 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1219 YAZ-based servers should now be uniform across operating systems in
1222 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1223 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1224 This allows yaz-marcdump to read large MARC batches (>2 GB).
1226 Modified all YAZ source files - except the source which is auto-generated
1227 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1230 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1231 corresponding to the existing *_setl() function. These allow option
1232 values containing arbitrary valuues.
1234 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1235 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1236 except that it returns an indicator of whether or not the sort
1237 criterion was accepted (0 for OK, -1 for invalid).
1239 --- 2.1.8 2005/06/07
1241 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1242 MARC output rather than returning "new" buffer.
1244 yaz-client warns about unknown init options.
1246 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1248 --- 2.1.6 2005/05/24
1250 Added support for SRW sort in Generic Frontend Server. Patch
1251 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1252 sortKeys - or NULL if none is provided.
1254 Fixed bug #307: It was impossible to specify indefinite/no timeout
1255 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1258 Added support for multiple languages and charsets to be specified in
1259 ZOOM. Each charset/language is separated by a blank. If negotiation is
1260 in effect in init-response, Option
1261 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1262 Code based on patch by Vasiliy Osadchuk.
1264 Fixed bug #306: infinite recursion that occurred when calling
1265 yaz_log_level_init as the first call (before other log level or
1268 Fixed bug in scan handling in front end server: if preferred-Position-In-
1269 Response was non-present, a NULL pointer referece was performed.
1271 --- 2.1.4 2005/04/26
1273 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1274 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1275 now defined for all those error codes. So instead of putting 109 in
1276 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1277 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1279 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1282 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1284 Program yaz-client now exits and produces an error message if multiple
1285 Z39.50 servers are specified on the command line (none or one allowed
1288 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1291 --- 2.1.2 2005/03/16
1293 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1295 Fixed bug #272: Preserve spacing for CCL terms.
1297 --- 2.1.0 2005/03/14
1299 Added support for virtual hosts and multiple backend servers for
1300 the YAZ frontend server. The configution is XML based and
1301 support specificition of CQL to RPN mappings and explain information.
1302 See section "Virtual Hosts" in the YAZ manual.
1304 Extended OPAC display utility. OPAC display utility renders
1305 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1306 to supplement yaz_marc_decode_wrbuf.
1308 Fixed a bug in MARC decoder that could caused it to crash for some
1309 invalid MARC records. More diagnostics and warnings where added in
1310 XML output (warnings, etc are stored in comments).
1312 --- 2.0.34 2005/02/08
1314 Fixes for UNIX domain sockets. Bug #261.
1316 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1318 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1319 Added yaz_marc_subfield_str which defines subfield lead string which is
1320 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1321 yaz_marc_endline_str which defines end of fields string used in
1322 YAZ_MARC_LINE format. Default string is newline.
1324 Experimental support for MarcXChange. This format can be produced
1325 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1326 http://www.bs.dk/standards/MarcXchange.xsd
1328 Added yaz-client commands scansize that sets maximum number of
1329 entries to be returned by scan.
1331 --- 2.0.32 2005/01/11
1333 Added support for SRW scan in yaz-client and Generic Frontend Server.
1335 * Added whereInList member to SRW Scan Term.
1337 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1339 Fixed NMEM system to return aligned blocks on the smallest boundaries
1340 that are suitably aligned for all possible types on the particular
1341 architecture YAZ is being built for.
1343 --- 2.0.30 2005/01/04
1345 Fixed numerious warnings that was issued with newer versions of GCC.
1347 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1348 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1351 Make YAZ Generic Frontend Server slightly faster.
1353 Enhance (and reduce) logging for Generic Frontend Server.
1355 Revert YAZ log system so that it flushes every write operation
1356 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1358 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1359 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1360 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1361 will effectively disable old definitions.
1363 --- 2.0.28 2004/11/09
1365 Added yaz_log_time_format which specifies log format using
1368 Added yaz_log_module_level which returns mask for a module. Value
1369 is non-zero mask a if module is enabled; zero if disabled.
1371 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1372 in include/yaz/cql.h.
1374 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1376 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1378 Fixed bug #172: RPM builds does not enable SSL.
1380 Doxyfile.in part of dist. Doxyfile generated by configure.
1382 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1383 are given and the corresponding component does not exist.
1385 Extend CCL documentation in YAZ reference. Describe r=r.
1387 --- 2.0.26 2004/10/01
1389 Fixed MARC->MARCXML conversion to properly deal with
1390 fields, subfields, indicators having non-ASCII characters.
1392 Fixed MARC->MARCXML conversion so that ASCII control characters
1393 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1396 Added YAZ GFS support for conversion from Z39.50 surrogate
1397 diagnostics to SRW surrogate diagnostics.
1399 Bug fix: YAZ GFS did not return schema in explainResponse.
1401 --- 2.0.25 2004/09/30
1403 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1404 now converts recordSchema to elementSetName as well as schema URI.
1406 Fixed bug in COMSTACK that prevented HTTP request packages from being
1409 --- 2.0.24 2004/09/29
1411 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1412 does not require white-space before and after the dash in a range, e.g.
1413 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1416 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1417 due to new GCC removing "redundant" code.
1419 Added yaz-client commands scanpos and scanstep that sets preferred
1420 position and step-size for scan.
1422 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1424 Added CCL utility ccl_qual_buf which parses one or more CCL
1425 spec lines in a buffer.
1427 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1428 of name and value - ignoring empty lines and comments.
1430 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1432 Added odr_get_element_path which returns current element path for an
1433 ODR handle. This utility is useful in error handling or user-defined
1436 Added ODR_PRINT utility odr_set_stream which is is a more generic
1437 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1438 to a write function and pointer to close function. The close function - if
1439 non-NULL - will be called during odr_destroy.
1441 Fixed bug in CCL parser where truncation char was not removed from
1442 right side when truncation=both was in effect.
1444 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1447 --- 2.0.23 2004/08/11
1449 Fix buffer overrun in CQL parser when dealing with proximity (%).
1451 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1452 to UTF-8/UCS conversion is now only based on codetables.xml.
1454 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1456 --- 2.0.22 2004/08/06
1458 Add support for more "commit changes" in ZOOM (uses Extended Services).
1460 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1463 Yet another small fix for configure of SSL.
1465 --- 2.0.21 2004/05/14
1467 Fix SSL libs for configure when --with-openssl=DIR is given.
1469 --- 2.0.20 2004/05/10
1471 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1473 SSL comstack now uses yaz.pem certificate file on server side
1474 by default. Certificate filename can be configured by calling
1475 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1477 Fix bug regarding multiple calls to ZOOM_connection_connect.
1479 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1481 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1482 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1484 ZOOM now allows inspection of X509 peer certificate for verification.
1485 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1487 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1488 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1489 as "modular" but it simplifies things.
1491 Added cs_get_peer_certificate to that returns peer X509 PEM.
1493 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1494 NULL if SSL is unavailable.
1496 Documentation about MARC decoding tools.
1498 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1500 --- 2.0.19 2004/03/30
1502 Rename CHANGELOG to NEWS to follow GNU style packing.
1504 Fix bug with missing initialization of member in init_diagnostics.
1505 This bug affects threaded version of GFS server.
1507 --- 2.0.18 2004/03/20
1509 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1512 Ensure zlib.dll is packed with Windows install.
1514 --- 2.0.17 2004/03/17
1516 Fix encoding of xsd:string to use text instead of CDATA.
1518 Fix endless loop in CQL parser with unbalanced ".
1520 Use a more compact way to store MARC-8 conversion tables.
1522 --- 2.0.16 2004/03/16 Debian only
1524 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1527 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1532 --- 2.0.15 2004/03/01
1534 Another fix for decoding of XML packed records.
1536 --- 2.0.14 2004/02/25
1538 Fixes for Chunked encoding. White space not ignored after length spec.
1540 Update NS and use default NS for SRW diagnostic elements.
1542 --- 2.0.13 2004/02/23
1544 Implement ZOOM_resultset_cache_reset which resets record cache.
1546 Implement ZOOM_resultset_sort which sorts a result set.
1548 Implement chunked HTTP transfer.
1550 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1552 --- 2.0.12 2004/02/16
1554 Added member 'schema' to bend_explain_rr structure so that backend
1555 can specify explain record identifier. Defaults to Zeerex 2.0.
1557 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1559 --- 2.0.11 2004/02/16
1561 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1564 Added init command for yaz-client which sends "extra" init request.
1566 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1567 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1569 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1571 Make ZOOM error code for "invalid query".
1573 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1575 --- 2.0.10 2004/02/05
1577 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1580 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1582 Added option -p <file> to make Generic Frontend Server to write PID file.
1584 Added option -D to put Generic Frontend Server in background on its own.
1586 Make ZOOM C recognize option "password". If unset, "pass" is used
1587 (for backwards compatibility).
1589 Fixed a bug in Generic Frontend Server that could make it crash if a
1590 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1593 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1594 Must be issued before open, in order to be in effect.
1596 --- 2.0.9-6 2004/01/12 Debian/Windows
1598 Make the SRU server more picky WRT unknown params, etc.
1600 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1602 New YAZ client command, options, that sets Z39.50 options.
1604 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1605 options from a string of tokens (one token for each option bit).
1607 Update SRW diagnostic code messages.
1609 --- 2.0.9-5 2004/01/07 Debian/Windows
1611 Handle user defined stylesheet for SRW/SRU.
1613 --- 2.0.9-4 2004/01/06 Debian/Windows
1615 Fix bug in decoding of Content-Length.
1617 --- 2.0.9-3 2004/01/06 Debian/Windows
1619 Fix a bug with decoding of XML packed records.
1621 --- 2.0.9-2 2004/01/05 Debian only
1623 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1625 Fix bug in SRW/SRU diagnostics decoding.
1627 --- 2.0.9 2004/01/05
1629 Fixed bug in Generic Frontend Server which could drop records exceeding
1630 preferred message size. Reported and fixed by Irina Dijour.
1632 Fixed calculation of package size for structured records in Generic
1633 Frontend Server. Reported and fixed by Irina Dijour.
1635 Fixed namespace for SRW/SRU diagnostics.
1637 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1639 --- 2.0.8 2003/12/22
1641 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1642 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1645 CQL changes to reflect recent changes to the specification:
1646 * Documentation talks about context sets instead of index sets.
1647 * Documentation talks about indexes instead of qualifiers.
1648 * The CQL-to-PQF transformer's configuration file now uses
1649 "index.set.name = <attributes>" instead of the old form
1650 "qualifier.set.name = <attributes>". (Both forms are still
1651 understood but the latter is deprecated.)
1652 * CQL terms with no explicit index specified are now interpreted as
1653 cql.serverChoice instead of srw.serverChoice (which of course
1654 behaves exactly the same.)
1656 --- 2.0.7 2003/12/16
1658 MARC conversion can now generate ISO2709 output in another
1659 character set. yaz-marcdump uses this facility if you invoke it
1662 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1663 functions from there can be used from C++.
1665 --- 2.0.6 2003/12/04
1667 Frontend server now transfers memory from decoded packages to stream
1670 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1671 references to show up.
1673 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1674 the ZOOM Abstract API. The older names for the same options are still
1675 also supported for the benefit of old applications.
1677 ZOOM-C supports "implementationId" and "implementationVersion" options
1678 to go along with "implementationName". These allow the user code to
1679 specify identification strings to be sent to servers.
1680 Add OID for the new ExtLite attribute set.
1682 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1683 as requested/supplid by Ere Maijala <ere@atp.fi>
1685 For generic frontend server, reverse the order of
1686 "toolkit-supplied / application-supplied" strings sent as implementationId,
1687 Name and Version. Also, remove the spaces around the slash. This brings
1688 the GFS in line with the behaviour of ZOOM-C on the client side.
1690 Add function ZOOM_scanset_display_term.
1692 yaz-client shows scan displayTerm if present.
1694 Utility yaz-iconv is now installed by default along with the man page
1697 Extend configure check for OpenSSL to use pkg-config where available (such
1700 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1701 server to specify uid/gid/mask for socket using the format
1702 unix:[user=uid,][group=gid,][umask=mask,]file=path
1703 If file= is omitted the existing format is assumed, e.g.
1705 in which case the mask is 0666 (rw for everybody).
1707 Major restructure of YAZ source. All source in libyaz is in src directory.
1708 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1709 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1711 Added man page for utility yaz-marcdump (used to be called marcdump).
1712 yaz-marcdump is installed by 'make install'.
1714 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1715 of incoming package failed.
1717 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1719 Change prototype of odr_perror: add const to message string.
1721 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1723 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1724 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1725 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1726 DNS lookup. There should not be any compatibility problems with this
1727 assuming that blocking=1 or 0 is used.
1729 Fix bad reference in UNIX comstack in function cs_addrstr.
1731 Fix for compilation on AIX.
1733 The generic front-end server (server/seshigh.c) now supports returning
1734 Init diagnostics to the client in User-information-field, in
1735 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1738 --- 2.0.4 2003/09/04
1740 Allow any CQL relation (not just all,any,exact,scr).
1742 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1743 that features the same UI.
1745 Implemented command update0 in YAZ client which is equivalent to
1746 update but uses old of Ext Update ASN.1.
1748 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1749 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1750 Previously no OID was used for this info.
1752 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1753 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1754 returns 'malformed search term' otherwise.
1756 SortResponse member resultCount now set to NULL in sort handler of
1759 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1762 Add three new utility functions for translating OIDs between various
1763 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1764 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1765 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1766 char *oid_to_dotstring(const int *oid, char *oidbuf);
1767 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1769 Reverted modifications for ES Update definition for z_IU0Update
1770 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1771 is back to YAZ 2.0.2.
1773 String value attributes for CCL parser.
1775 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1776 which their FirstSearch server returns in Init responses, sometimes
1777 carrying useful diagnostic information when Init fails. This has the
1778 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1779 "z39.50/oclcui.asn", where its definition is somewhat different from
1780 what OCLC document on their web-site, as required to interoperate with
1783 Support for anonymous authentication in yaz-client. Use the command
1786 * Fix the OID of the Index Data-local "admin" Extended Service from
1787 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1788 the 1000, which indicates a locally-defined OID, was a mistake.
1790 --- 2.0.3 2003/06/20
1792 Fix CCL directive @case handling so that it affects string match for
1793 both CCL keywords and qualifiers.
1795 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1796 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1797 Decoder has been updated with ASN.1 changes as listed in
1798 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1799 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1800 z_IUUpdate, remains unchanged.
1802 ZOOM_record_get may now return a record in a specific character set.
1803 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1804 "from" is the character set of record as returned by target. "to" is
1805 the character set to be returned. If omitted, "to" is UTF-8.
1807 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1809 New ODR utility, odr_getelement, which returns name of element for
1810 which encoding/decoding failed.
1812 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1813 in cases where a required element was omitted.
1815 Bug fix: some MARC8 sequences were not converted.
1817 New ZOOM option "step" which specifies number of records to be
1818 retrieved in one chunk. Used in conjunction with "start" and "count".
1820 SRW support for yaz-client. Use scheme http: to use it, e.g.
1823 yaz-client no longer does (un)intelligent character set conversions
1824 by default. Can be enabled with charset and marc_charset commands.
1826 xmalloc trace fix for 64-bit systems such as DEC alpha.
1828 Solaris 2.6 compile fix.
1830 New function, cql_strerror() translates SRW error codes, as returned
1831 by cql_transform_error(), into human-readable English strings. Used
1832 in yaz-client diagnostics when appropriate.
1834 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1835 converts it into a type-1 query which is sent to the server. This
1836 makes CQL available for use with all Z-servers, as opposed to the tiny
1837 minority that can handle CQL queries themselves.
1839 --- 2.0.2 2003/04/28
1841 New Debian package layout similar to the Redhat Package layout.
1843 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1844 and search result respectively.
1846 --- 2.0.1 2003/04/25
1848 Redhat package is now several packages: libyaz (runtime libraries),
1849 libyaz-devel (development and documentation, and yaz (utility programs).
1850 Package spec file by Morten Bogeskov.
1852 New member 'schema' in struct bend_fetch_rr which the name of requested
1853 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1854 handler MAY set this to reflect the schema of the returned record.
1856 New member 'display_term' in struct scan_entry. GFS now sets member entries
1857 and allocates scan entries to be filled by user scan handler. In previous
1858 version, entries member was allocated by the scan handler. That still works,
1859 but the GFS will ignore member display_term - assuming it was NOT set by
1860 the handler. The fact that the GFS now allocates the entries both allows
1861 for new members and makes a scan handler easier to write.
1863 Fix CQL lex buffer overflow.
1865 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1866 SRU default recordPacking is string.
1868 SRU protocol support for frontend server.
1870 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1872 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1874 Added scan for the ZOOM shell (zoomsh).
1878 * String Identifers for Schemas (Amendment 5).
1879 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1880 Old definition for schema
1881 Odr_oid *schema; /* OPT */
1886 Z_InternationalString *uri;
1887 #define Z_Schema_oid 1
1888 #define Z_Schema_uri 2
1891 * resultCount parameter to Sort Response (Amendment 1).
1892 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1894 Support for SRW 1.0 over HTTP. This is an optional feature and
1895 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1898 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1899 on the same port. SRW SearchRetrieveRequests are mapped
1900 to bend_init,bend_search,bend_fetch,bend_close.
1902 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1904 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1905 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1907 ZOOM connections are SRW based if schem http is used for hostname
1908 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1909 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1911 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1912 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1913 distance=n, order=true/false, relation=le, prox unit=word. If
1914 n is omitted, distance 1 is used.
1916 Fixed problem with C compiler include path in wrong order.
1918 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1919 on Solaris. Patch from Ko van der Sloot.
1921 New MARC decode API. All new functions operate on a yaz_marc_t
1922 handle. The most important new functions are: yaz_marc_create,
1923 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1924 decode and destroy respectively. Decoder can produce formats
1925 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1926 include/yaz/marcdisp.h.
1928 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1929 to UTF-8, UCS-32, wchar_t or Latin-1.
1931 * Prototypes for yaz_iconv_-functions moved to separate header
1932 include/yaz/yaz-iconv.h.
1934 Make a few private functions 'static' in unix.c. This prevents
1935 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1937 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1938 are set when Init Response is received.
1940 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1941 but returns diagnostic set as well.
1943 New function yaz_strerror which is a portable wrapper for
1944 strerror/strerror_r/GetLastMessage.
1946 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1947 is returned for MARC. If type is "oai", then OAI MARC is returned.
1949 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1952 --- 1.9.2 2002/11/26
1954 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1956 Fix bad race conditions on SIGTERM and terminate gracefully in
1959 Move retrieval (data1) module to Zebra since nobody seems to be
1962 Add GRS-1 render for ZOOM using same format as yaz-client.
1964 --- 1.9.1 2002/10/05
1966 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1968 Fix broken ESpec handling in data1 module.
1970 SGML reader parses comments and makes them part of the data1 tree.
1972 Added several type casts so that YAZ compiles as C++ code.
1974 ZOOM didn't handle PDU encoding failures properly.
1976 Added more Bib-1 diagnostics (approved extensions).
1978 GNU configure: better check for iconv.
1980 More portable use of accept, getpeername. Check for socklen_t. Use
1981 int/size_t if socklen_t is not defined.
1985 PQF parser rejects bad queries - including those with extra
1986 characters in them. PQF parser used to silently ignore that.
1987 Cleaner API for PQF added, which allows you to get detailed
1988 error information for bad queries (see yaz/pquery.h).
1990 Fixed bug in ZOOM_record_get for type "database".
1992 Implemented mini iconv library supporting conversions between
1993 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1995 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1997 --- 1.8.9 2002/08/20
1999 Fixed ZOOM C record cache so that preferredRecordSyntax and
2000 elementSetName is used to check for already fetched records.
2002 --- 1.8.8 2002/08/02
2004 Added three members in bend_initrequest structure to facilitate
2005 character set negotiation.
2007 Fixed a bug in frontend server that could cause indefinite
2008 loops under rare conditions.
2010 Revised character set utilities (charneg.h) so that encoding
2011 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2013 For PQF, directive @term <type> sets term type for Scan/Search.
2014 Here <type> is general, string, numeric, null. The term type
2015 is inherited - just like @attr.
2017 New call odr_set_charset that sets character set conversion for
2018 international-strings on a ODR stream. Prototype is:
2019 int odr_set_charset(ODR o, const char *to, const char *from);
2020 The InternationalString is still represented as C string in YAZ
2021 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2022 won't). On the protocol level, you can use any encoding.
2024 Support for UNIX sockets in ZOOM.
2026 Solaris recv sometimes returns errno == ENOENT. It is treated as
2027 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2029 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2030 both client and server. Code by Morten Bogeskov.
2032 --- 1.8.7 2002/05/22
2034 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2035 that they can be used directly from Visual Basic. You must recompile
2036 your windows APP if you're using ZOOM.
2038 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2039 Commands "lang" and "charset" sets language and character set respectively.
2040 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2041 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2043 Attributes from multiple CCL fields may be OR'ed rather than merged
2044 using directive "@field or". Fields are still merged by default -
2045 equivalent to "@field merge".
2047 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2050 Fixed bug in zget for parameter ExtendedServicesResponse.
2054 --- 1.8.6 2002/03/25
2056 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2058 Client displays USR.1:SearchResult-1 (hits per term).
2060 Additional Search Info for search in Generic Frontend Server.
2062 Fixed CCL parsing of "field=s".
2064 WIN32 installer - using the excellent NSIS software from nullsoft.
2066 Fixed CCL parsing of "field = - <number>".
2068 Added function yaz_marc_decode that decodes MARC for line mode
2069 display or XML (similar to that used by JZKit).
2071 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2072 Z39.50. But ISO/ILL was, however.
2074 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2075 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2077 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2078 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2080 --- 1.8.5 2002/02/03
2082 New YAZ client features: Command completion and new commands:
2083 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2084 Code provided by Jacob Poulsen.
2086 New call oid_trav, that visits all registered OIDs via callback.
2088 Function ZOOM_record_get now returns const char pointer rather than
2089 void pointer. It saves a lot of type casts.
2091 For YAZ client, command "auth" now allows you to set authentication
2092 in IdPass style. It is enabled when three tokens are given - order
2093 is user, group and password.
2095 Fix memory leaks in MARC record handling for ZOOM.
2097 New option for YAZ client, -k <kilobytes> that sets
2098 maximum record size. Similar to -k option for generic frontend
2099 server and yaz-ztest.
2101 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2103 Prefix query parser reports "fail" when bad attribute set is given.
2105 Fix in MARC decoder. Proximity logging. Fix for attribute set
2106 in scan handler for server. Patches by Shigeru Ishida.
2108 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2111 Configure option --with-openssl=<dir> now works when a directory is
2112 specified. Patch provided by Morten Bogeskov.
2114 New option for YAZ client, -u <auth>, that sets authentication.
2116 ZOOM fix: error information was sometimes "missing", since error
2117 was cleared/reset too when it shouldn't.
2119 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2121 --- 1.8.4 2002/01/04
2123 Scan for ZOOM API. New object ZOOM_scanset. New functions
2124 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2125 ZOOM_scanset_destroy.
2127 New ZOOM function, ZOOM_connection_last_event, that returns type
2128 of last event (such as "receive data", "send data", "apdu received",
2131 New ZOOM option, schema, that specifies schema for retrieval.
2133 New CCL feature. Qualifiers can be aliases for one or more
2134 other qualifiers (if more than one is given, OR is used).
2136 ZOOM uses named result sets if target supports it.
2138 Two new YAZ client commands: . (dot, which sources a script of YAZ
2139 client commands), and ! (to execute shell command.). Implemented
2142 Working on Debian packages.
2144 --- 1.8.3 2001/11/19
2146 YAZ client enables named result sets only if target supports it.
2148 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2150 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2151 with key="host" to get same result.
2153 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2154 Function Z3950_resultset_record(s) returns references to records
2155 "owned" by resultset. To become owner use Z3950_record_clone.
2157 Function z_ext_record handles Extended Services. Thanks to
2160 --- 1.8.2 2001/11/12
2162 CCL Parser fix: ignore token comma when dealing with and-lists.
2164 Documentation updates for COMSTACK.
2166 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2167 Changed prototype Z3950_records. For some functions, int parameters
2168 were changed to size_t.
2170 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2173 New MARC decode/display function, marc_display_exl, which properly rejects
2174 non-ISO2709 records. YAZ client uses it.
2176 --- 1.8.1 2001/10/29
2178 Fix bug: local attribute set wasn't set correctly in PQF strings.
2182 * Old Z39.50 codecs no longer supported.
2184 Added ZOOM C binding. See http://zoom.z3950.org/
2186 Renamed states for COMSTACKs to avoid confusion with events.
2188 Implemented cs_look and proper cs_rcvconnect.
2190 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2192 Configure detects POSIX threads on OpenBSD.
2194 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2195 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2197 When error is returned from present handler, non-surrogate diagnostic
2198 is returned in present response (and fetch handler is no longer called).
2200 * Minor adjustments to pquery parser (PQF). Token characters may be
2201 escaped by using backslash (C-style).
2203 PQF parser allows string attribute values to be specified. For @attr,
2204 non-numeric characters after the equal-sign are treated as strings
2205 (e.g. @attr 9=title).
2207 CCL trunction character may be defined (@truncation in file)
2209 * function zget_ExtendedServicesRequest sets waitAction to
2210 waitIfPossible (was wait).
2212 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2215 CCL operator names may be set in field definition files (CCL_bibset).
2216 See ccl/bib1 for an example.
2218 Fixes in ASN.1 compiler for C++ compatibility.
2220 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2221 and "op_or" to avoid conflict with C++.
2223 Fixed problem with GNU readline detection on Redhat 7.0.
2225 Added step-size for Scan backend handler.
2227 Fixed bug that made the frontend server crash when no attribute
2228 set was specified for scan.
2230 Front-end server automatically switches to original working directory
2231 when installed as an NT service. Previously -w had to be specified to
2234 Added extended attributes for retrieval module (data1), so that data1
2235 records carry d1_readXML/SGML attributes. d1_read also supports
2236 null-data rules ( <tag/>)
2238 On UNIX when POSIX threads are available, a separate library libyazthread
2239 is created. Programmers should link with that library and the yaz library
2240 when using threads. The reason for the split was that some applications
2241 on Linux, such as Apache, doesn't work well when using shared objects that
2244 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2245 (or any frontend server) in SSL mode by specifying ssl: followed by
2246 address. Only tested on UNIX.
2248 Added feature for CCL module. Virtual structure s=al or s=ol generates
2249 and-list and or-list respectively instead of phrase search.
2253 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2254 log_mask_str. This was done to avoid name conflicts with other libraries
2255 (such as other PHP extensions).
2257 Added raw OID member for preferred record syntax (request_format_raw)
2258 and returned record syntax (output_format_raw) for backend fetch method.
2260 Config file yaz-config now accepts options so that it returns specific
2261 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2263 Shared library support for UNIX using GNU libtool.
2265 * Modified backend interface. Request/Response struct's replaced by
2266 one read/write C struct. For example bend_fetchrequest and
2267 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2268 Every handler - even search has to be registered in bend_init
2269 handler. This means that the YAZ library no longer refers to
2270 external functions and it makes it possible to make the whole
2271 thing a single DLL/SO.
2273 Added Segment handler for backend server.
2275 Added Zmbol/Zebra administrative functions to YAZ client.
2277 Threaded frontend server on UNIX (when POSIX Threads are available).
2278 Starting the server with option -T enables multi-threading.
2282 Added configure option --enable-comp/disable-comp to control use
2283 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2284 located in sub directory asn.
2286 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2287 in ${exec_prefix}/bin along with the other programs yaz-client and
2290 GNU automake used to maintain makefiles.
2292 Added several OID's.
2294 Changed retrieval module so that we can load records with no abstract
2295 syntax defined. Tagpaths in these records are fully composed of string
2298 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2302 On UNIX, the generated makefile now supports a proper 'make install'.
2303 The prefix can be set via GNU configure to set the install location
2304 (default is /usr/local).
2306 * YAZ programs client and ztest were renamed to yaz-client and
2307 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2308 locations, such as /usr/bin,/usr/local/bin,etc.
2310 * YAZ Header files were moved from include to include/yaz. YAZ Header
2311 files are referred to as include <yaz/log.h> rather than <log.h>.
2312 The YAZ include path (-I ..) is therefore the same as before. Programmers
2313 should update their #include statements or use -Ipath/include/yaz
2314 instead. The main motivation for doing this change is that YAZ header files
2315 can be installed in "standard" locations /usr/include,/usr/local/include
2316 without introducing conflicts, since ALL YAZ header files are stored
2317 in subdirectory yaz (under /usr/include for example).
2319 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2320 rather than project/workspace files. We switched because project files
2321 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2324 Changed name of logging function, logf, to yaz_log, to prevent name
2325 clash with some math-log functions. The YAZ header log.h defines logf
2326 to yaz_log (#define) so there should be no incompatibilities by this
2329 Added bend_start/bend_stop handlers for server. These handler are
2330 called on start/stop of server. For windows they are called whenever
2331 a service is started/stopped.
2333 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2334 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2335 in util/yc.tcl. The auto-generated C code structures are, in a few
2336 cases, incompatible with the old decoders. There are differences in the
2337 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2338 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2339 The preprocessor variable ASN_COMPILED is defined when the compiled
2340 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2341 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2342 wish to use the old encoders/decoders you can specify --disable-yc
2345 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2346 version so that it supports both new - and old version of DB Update
2348 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2349 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2350 change. The name parameter can be set to 0 in which no name is specified
2351 for the construction. The macros odr_implicit and odr_explicit sets name
2352 parameter to zero for the construction involved. New macros
2353 odr_implicit_tag and odr_explicit_tag are similar to the others,
2354 except that a name parameter is added. For programmers' that don't use
2355 ODR they probably only need to change the call to z_APDU and z_External.
2357 Added access control facility by interfacing the TCP wrapper library.
2358 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2359 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2360 name of the daemon and enables the access control as specified in
2361 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2363 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2364 den Dool <H.M.vdnDool@kub.nl>.
2366 Added reference ID parameter to most functions in server API - refer
2367 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2369 Changed name of ccl library to libccl.a (was ccl.a).
2371 Fixed bug in decoder for Explain (Category TargetInfo).
2373 Added support for GNU readline in client. Thanks to Jacob Poulsen
2374 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2376 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2377 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2378 IMPLEMENTATION! This change was made to the development version before
2379 the ZIG decided to retract the amendment. If any users MUST be
2380 compatible with the original Update definition, PLEASE CONTACT US, and
2381 we will include a separate definition corresponding to the old Update
2382 ES. Note that because of the change to the ASN.1 of the
2383 TaskPackageRecordStructure we cannot define a single structure that
2384 will support both versions.
2386 * Added const modifier to buffer parameter for some ODR/BER encoding
2387 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2388 completeWAIS, odr_dumpBER.
2390 Fixed bug in client.c which caused a crash when a scanResponse didn't
2391 contain positionOfTerm.
2393 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2394 * will cause an error in a client if a non-YAZ target sends both a
2395 * list of Scan entries and non-surrogate diagnostics.
2397 Retrieval module enhancements. Tag sets may be typed in the reference
2398 to it. From the .abs-file the "tagset" directive takes a third optional
2399 integer type for the tag set referenced. From a .tag-file the "include"
2400 directive takes a third optional type as well. The old "type" directive
2401 in the tag set itself is still recognized but acts as the default type
2404 Backend interface change. Individual Scan terms returned from bend_scan
2405 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2406 in include/backend.h.
2408 Retrieval module enhancements. Multiple tag sets and attribute sets may
2409 be specified in abstract syntax specs. Revised the error/warning for
2410 logging messages reported by the retrieval module when reading the
2413 Object Identifier system (oid_..) changed. The API is backwards
2414 compatible but the oid-routines now allocates new OID's when needed.
2415 Raw OID's may be specified in oid_getvalbyname.
2417 YAZ now uses GNU configure to generate Makefile(s).
2419 * Minor changes in some of the member names of DeleteResultSetRequest and
2420 DeleteResultSetResponse. See include/proto.h.
2422 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2423 and added member 'languages' in TargetInfo (which was missing).
2425 Changed the way attribute sets are handled in the retrieval
2426 module. These are now cached, just like the abstract syntaxes
2429 Changed YAZ so that it links with compiled ASN.1.
2431 Added Explain-schema definitions and mapping routines. The following
2432 Explain categories have been implemented: AttributeDetails,
2433 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2435 Fixed minor bug in Windows version of Server Library.
2437 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2439 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2441 Added EXTERNAL: UNIverse Resource Report (non-standard).
2443 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2444 ENUMERATED and SET OF.
2446 * Added 'const' to some of the char pointer arguments for the
2447 functions, data1_read_node, data1_getelementbytagname,
2448 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2451 Fixed bug in data1_insert_taggeddata - the last_child member of
2452 parent wasn't initialised.
2454 * Changed data1_read_record and data1_read_node so that the supplied
2455 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2456 doesn't refer to any parts of the "SGML"-buffer.
2458 Fixed bug in server library (Windows version of statserv_remove).
2460 * Changed code so that it compiles as C++. The type definition
2461 of Odr_fun which is a member of Odr_arm was changed. The result is,
2462 that an explicit typecast is needed for the fun pointer when
2463 using Odr_arm - as in:
2464 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2466 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2468 Implemented the new structured date and time definition as approved
2469 by the ZIG. Added schemaId element to the specificTag in Espec-1
2470 (also approved at the last ZIG). Thanks to RVDM.
2472 Added some Object identifiers (RVDM).
2474 Changed the Update Extended Service (RVDM).
2476 Added command "refid" to client which specifies referenceId for
2477 the following requests.
2479 Implemented extended service handling for server. See ztest.c
2480 for an example as well as backend.h. New handlers are registerd
2481 in the Init handler.
2483 * Changed interface for sort in server.
2485 Added new members to statserv_options_block. It allows a server
2486 to read options from another source than just the command line. Thanks
2487 to Charles Woodfield.
2489 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2490 renamed to zboolean. Some C++ compilers complained about the name.
2492 Minor changes to gils.abs. Added index 's' (sort) on title
2493 and date/time-last-modified.
2495 --- 1.4pl2 1998/1/30
2497 Fixed bug in server library regarding inetd mode (-i). This bug
2498 was introduced by release 1.4.
2500 --- 1.4pl1 1998/1/29
2502 Added sort facility in client and backend server interface.
2504 Fixed problem with dependencies in Makefile(s).
2506 Fixed bugs for encoders/decoders of extended services and
2509 Implemented sub-tree feature for schemas. Sub-trees are
2510 referenced in *.abs-files. See explain.abs for an example
2511 of the use of this feature.
2513 Modified bib1.att; local attributes for ANY didn't include
2514 ANY itself (only affects use of the retrieval module).
2516 Fixed bug in plain SGML reader in function data1_read_node:
2517 tags with prefix "var" was incorrectly interpreted as variants.
2519 Added feature "sub-schemas" to enable references to - and definitions
2520 of - group of elements.
2522 * Removed member parent from type data1_element (in data1.h).
2524 Implemented function odr_nullval() that returns the value of
2527 * Removed member num_children from data1_node (in data1.h).
2529 Made NT service interface part of the server library. The
2530 function statserv_main uses the NT service when required and
2531 calls the statserv_start / statserv_close routines.
2533 Routine zget_SearchRequest and zget_PresentRequest fills
2534 resultSetName/Id member with "default" instead of "Default".
2536 Fixed memory leak in server. Request queue member wasn't freed.
2538 Fixed nmem_exit so that memory is freed.
2542 Revised the CCL parser utility to be thread safe.
2544 Added function, oid_ent_to_oid, to replace the function
2545 oid_getoidbyent, which is not thread safe.
2547 * Added nmem_init and nmem_exit to initialize and release
2548 NMEM resources. Function nmem_init should be called once in the
2549 initial thread before NMEM/ODR is used. statserv.c and client.c
2550 have been changed accordingly. The change was necessary to make
2551 NMEM thread safe. The NMEM memory pool is shared amongst threads
2552 in a process. Unix-based applications will still work fine without
2555 Added NT Services interface for the the Z39.50 (statserv) Server.
2556 Refer to the ztest.c source on the usage.
2558 Windows 95/NT port using MSVC5.0. Project files are included in the
2561 * Defined new 'global' handle for the retrieval (data1) system. The
2562 new handled, data1_handle, describes the state of the data1 system.
2563 This handle is passed as first argument to virtually all
2564 data1 related routines. The functions data1_create and data1_destroy
2565 creates and destroys a data1 handle respectively.
2567 Added ODR encode stream member to all backend request structures
2568 init, search, scan etc. This stream should be used to allocate all
2569 memory used for the response when thread safe operation is needed.
2571 Changed the comstack utility, cs_addstr, to be thread safe. The
2572 returned hostname string returned by the function is now part the
2575 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2576 function. The cs_straddr takes a COMSTACK handle as argument, so this
2577 function must be used after cs_create and before bind/connect.
2578 This function is thread safe.
2580 Moved test server to 'ztest' directory - generic server code still
2581 in 'server' directory.
2583 Made prefix query (pquery.c) utility thread safe.
2585 Added new function modifier YAZ_EXPORT to 'export' public DLL
2586 functions when using windows (see include/yconfig.h).
2588 Added definitions to the OID database (util/oid.c) (RVDM).
2590 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2592 Added call to ccl_rpn_delete in client program.
2594 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2595 release of RPN structure.
2597 Added support for C++, headers uses extern "C" for public definitions.
2598 With input from RVDM.
2600 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2601 Thanks to Ronald van der Meer (RVDM).
2603 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2605 Added support for private extensions to the OID database
2606 (oid_setprivateoids()). Thanks to RVDM.
2608 Added optional, physical ANY (key replication)
2610 Fixed null-reference problem in GRS-1 output filter.
2612 Proximity operator added to Prefix Query Format (PQF).
2614 In test client command "base" accepts multiple databases.
2616 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2620 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2622 Smallish bug-fixes in the new encoders/decoders (explain).
2624 Bug fixed in DeleteRequest.
2626 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2628 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2630 Added SOIF syntax (using private OID for now) to retrieval module and client.
2632 Added Update extended service.
2634 Added SearchResult-1 additional info structure.
2636 Added optional CCL (ISO8777) interpreter as separate module. Available
2639 --- 1.2 1996/6/10 (1st anniversary release)
2641 Added Summary record syntax. Lightly tested.
2643 Added OPAC record syntax. Untested.
2645 Added ResourceReport service encoders/decoders. Untested.
2647 Fixed bug in z_Unit - wrong tagging on unitSystem.
2649 Fixed bug in the DiagRecs decoder.
2651 Added options for max PDU size and session timeout to frontend-server.
2653 Added documentation of query-language parsers and other supporting utilities.
2655 [frontend-server] Added Attribute set to the bend_scanrequest API.
2657 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2658 surrogate diagnostics were generated.
2660 [retrieval] Allow multiple local values for attribute.
2662 [retrieval] Allow multiple attributes per element in .abs files. index type.
2664 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2666 --- 1.1pl2 1996/4/10
2668 Minor changes, mostly specific to Zebra's requirements (retrieval)
2672 Repaired bug in frontend server when running multiple listening
2673 endpoints in dynamic mode.
2675 z_External() now won't break if a known, ASN.1 value comes encapsulated
2676 in an octet-string. The value will pass through unmodified in an Odr_oct.
2678 Added a bit of code to the demo client to decode & display
2679 ASN.1-structured records represented in the octet-aligned branch of
2680 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2682 Added z_ext_getentbyref() to the ASN module. Doc updated.
2684 * Completed the SCAN definition in the ASN module. This may break SCAN
2685 code based on older YAZ-versions at compile-time. The fix is easy -
2688 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2689 under the SCAN definition. Remember to initialize this, server-people.
2691 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2692 that this does not extend to ODR and ASN.
2694 Comstack allows insertion of established socket (primarily for
2695 inetd-operation of servers). Doc updated.
2697 Front-end server can now start from the inetd in TCP mode. Doc
2700 --- 1.0pl4 1996/1/24
2704 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2705 the rank and record number.
2707 Adjustments to the frontend server.
2709 Fixed diagnostic BER dumper. It ignored the file argument.
2713 Various changes to retrieval module.
2715 Changed the union discriminators of the protocol files from enums to
2716 ints paired with #defines.
2718 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2721 *Changed operator in the RPN structure to 'roperator', again to avoid a
2724 Fixed problems in Explain decoders/encoders.
2726 --- 1.0pl2 1995/12/6
2728 Memory bug in log module fixed.
2730 --- 1.0pl1 1995/12/5
2732 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2734 Bug in Explain DatabaseInfo module fixed.
2736 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2740 The shift to v1.0 signals that we now consider the *core* functionality
2741 of YAZ reasonably stable (the core being more or less equivalent to
2742 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2743 tested (Explain not at all - though that will happen soonish).
2745 Minor changes to code to support Windows port.
2747 Various minor changes after we're getting to use GRS-1 & co. more.
2749 Added Espec-1 format.
2751 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2752 of the protocol and it cannot be selected when encoding (maps into 'string'
2753 when decoding). Needed to talk to some servers.
2755 Demo client can request simple element set names.
2757 Added Diagnostic Format encoders/decoders.
2759 Added simple Close handling to frontend server (no hooks for resource
2760 reporting yet), and demonstration client.
2762 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2764 --- 1.0b3 1995/08/24
2766 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2767 handled incorrectly when records were requested in the searchResponse. This
2768 will only affect you if you use the frontend-server.
2770 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2771 Test-client will ask for and print GRS1. Ztest will return dummy records
2774 Added Explain encoders/decoders to the service-level API. Untested.
2776 Added Extended Services: Item Order encoders and decoders to the Service-
2777 level API. Untested. We could use a recent copy of the pertinent bits
2778 of the ILL protocol to add those bits.
2780 Added diagnostic format 1 encoders/decoders to the service-level API.
2783 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2784 odr_cons.c, which causes a more correct output.
2786 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2787 was always set to 0 when no records were requested in the searchRequest.
2789 * Added better external-handling. This shouldn't harm old code that
2790 *encodes* externals. It can break code that looks for a
2791 'single-ASN1-type' representation, since those types that are known
2792 are now decoded immediately. Look at the SUTRS sample code in
2793 seshigh.c and client.c. Documentation updated.
2795 Handling of structured records in bend_fetchresponse. Length -1 marks
2796 structured record, type is deduced from format field.
2798 --- 1.0b2 1995/06/27
2799 Fairly quick maintenance release to add SUTRS support.
2801 Fixed handling of SUTRS records in the demonstration client.
2803 * Added format field to the bend_fetchrequest and bend_fetchresponce
2804 structures of the backend API (frontend server). When the record is
2805 returned, the value of the format field is mapped to an OID. The
2806 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2807 of the record. The special value VAL_NONE in the bend_request means
2808 that no specific format was requested by the client. Documentation
2809 updated accordingly. Test server (ztest) will return a fixed dummy
2810 SUTRS record if your client requests SUTRS.
2812 Documentation updated accordingly.
2814 You can now set external libraries and RANLIB support in the top-level
2818 First public release.
