1 -- 4.2.12 2011/08/27 RPM package only
3 cql2ccl: fix conversion of terms: operator characters were not
6 -- 4.2.11 2011/08/25 RPM package only
8 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
9 CCL parser will map both # and ? to their regular expression
10 quivalents (. and .*).
12 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
13 of reserved CQL characters.
15 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
16 is, so that they are passed through.
20 ZOOM SRU mode: more aggressive re-connect.
22 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
23 made available as a utility function, declared in <yaz/logrpn.h>
25 rpn2cql_structure() supports proximity nodes (except that the Type-1
26 proximity node's "exclusion" binary is ignored, as there is no way to
27 express that in CQL). Fixes bug #4564.
31 Fix SEGV that could occur if set command of zoomsh was given without
34 Fix SEGV that could occur if unsupported transport was given for
35 COMSTACK - say https (when SSL was unavailable).
37 Build yaz-url on Windows too.
41 New utility to get web content. Header is url.h. A command line tool
42 yaz-url is part of the distribution and packages.
44 Fixes for SSL COMSTACK (when gnutls is in use).
46 New functions yaz_base64{encode,decode}. Header is base64.h.
50 ZOOM C includes HTTP response buffer as additional info if it fails
51 to decode the SRU response.
53 Make wrbuf_json_puts available.
57 zoom: throw diagnostic for invalid value for option "sru". Before a
58 bad SRU request was sent.
60 Adding new utility wrbuf_vp_puts.
62 Add cclxmlconfig.obj to win/makefile. It was missing completely.
66 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
67 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
68 redirect was used at the same time.
70 MARC line mode decoding: be less picky about length given - first
71 5 digits of header that is.
73 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
75 Changes to decoding of SRU records: a record with recordPacking=xml is
76 modified with a new root element <yaz_record> if the recordData contains
77 multiple children elements. This is to make the record XML parseable
80 RPN to SOLR conversion: encode special characters.
82 Generic Frontend Server: fix uinitialized member, stepSize.
86 Fix a bug in SRU decoding of records.. The database records stored
87 had un-initialized memory, but it would only be seen with yaz_record_render
90 Fix a bug in ccl_qual_dup introduced in 4.2.3.
94 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
98 Add new utilities to convert from CQL to CCL . These utilities have
99 prefix cql_to_ccl defined in cql.h.
101 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
102 lead to memory heap corruptions when ICU utilities were in use.
106 Make compilation work without Libxml2.
108 yaz-client: remove redundant blanks in display of searchResult-1 term
113 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
114 resulting CQL node (tree) in a new node CQL_NODE_SORT.
116 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
117 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
118 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
119 Note that the CQL sortby spec is only converted when the GFS is already
120 converting from CQL to RPN (cql2rpn element).
122 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
123 specify whether to collapse delimitors or not. The existing nmem_strsplit
124 do collapse (collapse parameter = 1).
126 Windows installer: For NSIS, set InstallDir depending on x86/x64.
128 Rename internal func yaz_use_attribute_create. While non-static, this
129 function is not declared in a public header.
133 Add -lCrun when linking with ICU on Solaris.
135 More quicks character set conversions for OPAC records.
139 fix problem with record_render: records were converted (character set
140 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
144 SRU: add methods for handling DADS SRU-proxy facets.
146 Separate OPAC record character set for ZOOM_record. yaz_record_render
147 allows a character set given as charset=from/opacfrom,to where 'from' is
148 the character set of a bibliographic record, 'opacfrom' is character set
149 of OPAC record and 'to' is the target character set.
153 yaz-client: show may XML format records. Command show followed by 'format'
154 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
157 src/stemmer.c: Avoid using unnamed union. It is not supported by some
160 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
163 Update yaz.spec to operate on both SLES11 / Centos 5.5.
165 RPM: Release includes 'indexdata' name. Use indexdata in release name so
166 this package can be distinguished from other vendors.
168 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
169 as determined by configure
171 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
173 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
174 returns no error and no record, the present request is considered
175 partial (only a subset of the records could be returned by backend), and
176 so it is appropriate to set Present Status to partial-4.
180 Move yaz-config man pages to section 1.
182 More documentation about SOLR.
184 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
185 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
186 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
187 peers on some Linux systems. However, in general that does not work
188 so YAZ can not rely on that to work. Debian changed behavior in this
189 respect from Debian lenny to Debian squeeze (still testing as of Oct
191 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
193 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
197 Fix yaz-config output: echo_source not set correctly by configure.
201 SOLR WebService support for yaz-client and ZOOM.
203 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
205 --- 4.0.12 2010/08/17
207 Z39.50 facet support. Facet specifications are passed for search in
208 other-information with ASN.1 as defined in facet.asn and OID
209 .10.1000.81.5 . Facets are expressed as an Attribute list as known
210 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
211 3 is limit (number of entries to get in response). yaz-ztest returns
212 dummy facets if a client asks for them.
214 --- 4.0.11 2010/07/09
216 CCL fixes: bug 2895 and bug 3539.
218 GR1-display: add comma in display - was removed by mistake in
221 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
223 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
225 --- 4.0.10 2010/06/18
227 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
228 result set from a connection. The result set will be on its own
229 thereafter; no operations on it will perform retrievals from a target.
230 Only cached copies are returned.
232 ZOOM C:fix case for HTTP servers responding with Connection:close.
233 Ensure that if there is a current task it is resumed (like fetching
234 more records in a result set) . Bug #3484.
236 PQF parser: use odr_atoi for Odr_int (not atoi)
238 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
239 values that contain any non-digits are treated as string attributes
240 (previously decoding only checked for leading character ([0-9]). PQF
241 encoding: attribute string values are not surrounded by double-quotes.
245 New utility for managing threads - thread_create.h.
247 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
248 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
249 but YAZ' implementation do.
251 Fixes for yaz_cond-functions on Windows 7.
253 DLL export more symbols.
255 zoomsh: show record do NOT render opac.
257 Remove *.la files from Debian and RPM packages.
261 Debian package libyaz-dev depends on libgnutls-dev again (was
262 removed in YAZ 4.0.6, but due to Libtool it is still needed
263 even though yaz-config do not list libgnutls libs).
265 ZOOM: Use only one WRBUF for returning string results for
266 ZOOM_resultset. Reduces memory usage for ZOOM in general.
268 ZOOM: ZOOM_connection do not use a shared pointer to
269 ZOOM_resultset after ZOOM_resultset is destructed by
270 user. Reverts to YAZ 4.0.4 behavior.
274 record-conv: fix problem with at least one XSL conversion -
275 due to probably incorrect usage of XML XSL documents.
279 Fix yaz-config for static mode and the use of SSL (gnutls).
283 Forward decl timeval struct in mutex.h and gettimeofday.h.
285 yaz-config: fix 'static' mode linking.
289 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
290 are wrappers for pthreads or Windows. For Windows these are put in
291 a separate DLL: yaz_cond4.
293 libyaz.la (whole source) is compiled with thread. If thread support
294 is enabled enabled, all source of YAZ is compiled with treading support.
295 This allows core utilities such as yaz_log to use thread facilities.
296 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
297 thread utilities. This commit moves mutex utilities (mutex.c) from
298 libyaz_server.la to libyaz.la.
300 yaz-json-parse displays leading text until error.
304 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
305 patch from Giannis Kosmas.
307 SRU: no longer URL encode SRU database. The URL for an SRU server is
308 a URL and such is alreeady encoded - at least when given with leading
309 http:// or https://. This reverts behavior to YAZ 3.0.50.
311 Support for new MARC XML notation TurboMARC which like MARCXML is a
312 complete representation of MARC/ISO2709.. This one, however, is more
313 compact and allows for faster processing with XSLT. TurboMARC can be
314 used in the marcdisp.h API, from the yaz-marcdump utility and from
317 yaz-ztest can be configured - via the database - to perform certain
318 delays when it performs operations search, present and single record
319 fetch. This allows testers to make yaz-ztest act as a real or even slow
320 Z39.50 server. Refer to the yaz-ztest man pages for details.
324 wrbuf_destroy allows NULL WRBUF passed to it.
326 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
328 Add ZOOM_connection_close.
330 No fixed size buffers for ZOOM shell - bug #3257.
332 tstodr: make it work on s390 platform.
334 New icu iterator-functions. The new icu_iter-functions makes it possible
335 to use ICU chains from many threads.
337 yaz-client: better syntax check for show command.
341 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
344 New simple local-file XML include facility which allows file glob-patterns.
345 Refer to yaz/xml_include.h.
347 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
350 ZOOM_record_get supports new parameter "format" which makes it format XML
353 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
354 JSONText in ECMA-262) is JSONValue, not JSONObject.
358 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
359 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
361 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
362 POSIX/Unix builds .so with major version 4.
364 Remove old LOG_-defines from log.h. They have been obsolete and
365 undefined by default for the last 5 years.
367 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
369 GFS: Remove socket (int *fd) from search_rr handler. The socket
370 descriptor ptr is a facility that allowed a search handler to supply
371 a socket which would serve as a callback - when search was complete.
372 This facility has now been in use for years.
374 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
375 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
376 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
377 returns 'const char *' rather than 'char *. The returned string is
378 read-only and should not be modified by applications. COMSTACK cs_close is
379 now a void function - it no longer returns int. No applications check for
380 the value and the implementations has always returned 0.
382 ZOOM: use size_t for scan hit counts and str size. Functions
383 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
384 occ (hit count) and len (string length) are now of type size_t pointer
385 rather than int pointer. This is to be able to represent large hit counts
386 and to also just to use the proper type for string length (strlen result).
388 New JSON parser. Refer to include/yaz/json.h .
390 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
391 Used to be int in some cases. Many wrbuf_-functions used to return an int
392 indicating some length.. These return values were never used. And so they
395 ODR: odr_malloc, odr_total now takes size_t for size.
397 clone_z_type: fix leak; occurred for encoding failures.
399 --- 3.0.52 2009/12/03
401 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
402 bug was introduced in 3.0.51.
404 --- 3.0.51 2009/12/02
406 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
408 tcpip comstack: fix leak for getaddrinfo.
410 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
411 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
412 Decoding of SRU "path" database is performed by private function
413 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
414 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
416 yaz-client: honor base command for SRU. Change when database setting
417 is applied for SRU and ensure it is kept when a connection is reset.
418 Change also the way errors are displayed or SRU (decoding of packages).
420 --- 3.0.50 2009/11/02
422 Add support for extra request / response data for SRU codecs and GFS.
423 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
424 for extra data response buffer and length. For the GFS, both request
425 and response data (XML) is carried in extra_args and extra_response_data
426 for the search handler. Patch by Ko van der Sloot.
428 ZOOM: For queries that cannot be converted to the specified rpnCharset,
429 ZOOM now returns a diagnostic on the client-side ('invalid query' /
430 10010). This fixes bug #2113.
432 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
433 cmdfile included a 'quit' command that would result in a memory violation.
435 --- 3.0.49 2009/10/01
437 Make a number of functions defined in xmlquery.c static. These have
438 never been declared in a public header file (yaz/xmlquery.h) and was
439 made public by mistake.
441 Improve speed of character conversions (iconv utilities). This makes
442 conversions from MARC-8 faster.
444 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
445 unless type desired is "raw". This will prevent type "xml" from
446 returning ISO2709 .. Which obviously can not be XML parsed.
448 Fix memory leak in ZOOM that would occur if option apdulog was used
449 on a re-used connection.
451 Frontend server logs HTTP requests.
453 Frontend server now sends Z39.50 close when it times out (sesssion has
454 been idle for too long). Versions 2.0.30 and earlier also sent close.
455 But due to a mistake this was disabled in all versions after that, i.e.
456 the server would just close the socket immediately.
458 yaz-client emits a better message when receiving an unrecognised
459 userInformationField.
461 Skip zero-length subfields when decoding ISO2709. This rare case happens
462 if a record has two FS characters in a sequence. Without this patch
463 there would be a reference beyond char array in using_code_len fragments
466 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
468 --- 3.0.48 2009/08/28
470 The show command offered by the zoomsh command now takes a 3d optional
471 parameter type which is what is passed to ZOOM_record. If the type
472 argument is omitted, "render" is used.
474 RPN to CQL conv may use USE string attributes (bug #2978).
476 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
478 --- 3.0.47 2009/07/08
480 Function yaz_xml2query allows a diagnostic element in the PQF XML
481 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
482 code and additional info respectively.
484 The BER BOOLEAN is now the integral type Odr_bool which still happens
485 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
486 typedef'd to Odr_int. This is still an integral 'int', but it may be
487 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
488 ASN-1 compiler as well as programs has been updated to use the new types.
490 --- 3.0.46 2009/06/08
492 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
493 only the bibliographic record was rendered. For type=opac, an OPAC
494 record is only returned if it is present.
496 iconv: small fix for encoding of advancegreek.
498 yaz-client: avoid double display of SRU/SRW records (bug #2798).
500 yaz-client: option auto_reconnect=on really reconnects.
502 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
504 server: avoid null ptr ref for for yaz_poll errors.
506 build: fix RPM build for RHEL 5.3.
508 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
510 --- 3.0.45 2009/03/31
512 Fixed bug #2709: TCP connect returns Invalid argument.
514 Fixed compilation for mingw.
516 Honor charset for raw records (ZOOM_record_get).
518 Fixed use of errno for threaded mode that was seen on Solaris 10.
520 Fixed argument passing with blanks in value for Windows Service.
522 Disable YAZ' own log rotate by default (no 1 GB limit).
523 The variable l_max_size which specifies the log file limit is set to 0
524 (DISABLED): This is due to the fact that YAZ is most often deployed using
525 logrotate. Also YAZ can not perform log rotate because of unsufficient
526 permissions (setuid).
528 --- 3.0.44 2009/02/17
530 List supported encodings in man page for yaz-iconv.
532 Fixed missing SSL libs for --libs output
534 Re-established OID record syntax application-xml. Nobody should use it
535 but we don't want to change soname because of this symbol being absent.
537 --- 3.0.42 2009/02/02
539 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
541 Added member named_result_sets for init handler struct for the GFS. This
542 allows a server to disable named result sets.
544 Removed OID record syntax application-xml.
546 Added support for rule-based transliterator for ICU wrapper of YAZ.
548 Fixed bug #1902: yaz-icu XML output.
550 Make YAZ checks Emacs friendly.
552 BITSTRING value shows value. Bug #2346.
554 ISO2709 decoding: skip control characters from indicator data.
556 Omit sort key by default in yaz-icu's output.
558 Allow combined single char options (again) for YAZ' options function.
560 Utility yaz-marcdump got option to display YAZ version (-V).
562 Allow YAZ to use ICU 3.4.
564 Added new ICU test case which illustrates removal of diacritics.
566 --- 3.0.41 2008/12/29
568 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
570 --- 3.0.40 2008/12/29
572 For configure, using option --without-xml2 also disables Libxslt/Libexslt
575 Fixed bug #2352: yaz-marcdump crashes for certain record.
577 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
579 Added support for Danmarc2 to UTF-8 conversion.
581 Added support for ISO5426 to UTF-8 conversion.
583 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
584 implementation version.
586 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
588 --- 3.0.38 2008/11/10
590 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
591 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
593 ZOOM C now interprets databaseName option for ZOOM connection as path
596 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
598 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
600 Dummy Libxml2 types no longer defined in headers of YAZ'.
602 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
605 --- 3.0.36 2008/09/26
607 Various ODR chapter fixes.
609 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
611 Added missing source for Windows compilation, mutex.c.
613 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
615 For SRU connections in ZOOM all records up to "count" are now fetched.
617 Fixed crash in generic frontend server (and yaz-ztest) which occurred
618 in Windows due to bad error handling for Libxml2.
620 Added facility for sending arbitrary records (ASN.1 any) using
621 ZOOM C's Extended service update. Patch by Sam Reynolds.
623 New options for ZOOM C's connection, logapdu which makes ZOOM log
626 --- 3.0.34 2008/06/18
628 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
630 --- 3.0.32 2008/06/12
632 Fixed memory violation that could occur when decoding UTF-8. This bug
633 was only present in 3.0.30 of YAZ.
635 --- 3.0.30 2008/06/06
637 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
638 GNU TLS is used by default (if found).
640 yaz-ztest returns OPAC records if a client asks for OPAC.
642 Improved speed of MARC-8 encoding.
644 Added support for lossy and loss-less MARC-8 encoding.
646 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
648 Added new Windows Service wrapper (sc).
650 yaz-client's itemorder command may now send a file.
652 Fixed yaz-marcdump to allow the use of NS prefix for record element.
654 Added new function yaz_log_xml_errors.
656 Allow (but warn) unknown XML attributes in MARCXML parsing.
658 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
660 The UTF-8 to MARC-8 conversion now uses a different set of characters
661 for Greek symbols. Bug #2120.
663 --- 3.0.26 2008/02/21
665 Added yaz_daemon (daemon.h).
667 Fixed bug #2068: pkg-config trouble
669 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
671 --- 3.0.24 2008/01/28
673 Document --with-xml2 option.
675 Added OPAC XML XSD (etc/opacxml.xsd).
677 Allow glob mask for name attribute in retrieval element for the
678 generic frontend server's retrieval facility.
680 Changed yaz_poll_poll to return yaz_poll_except for all returned events
681 except POLLIN/POLLOUT.
683 Fixed error handling in cs_listen. Bug #2037.
685 --- 3.0.22 2008/01/20
687 Fixed version in yaz/yaz-version.h.
689 Fixed bug #2027: Crash when closing connection.
691 Changed configure so that ICU support is only enabled if only ICU
692 and Libxml2 is available (because the ICU chain is XML based).
694 --- 3.0.20 2008/01/15
696 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
697 is built. Only this DLL depends on the ICU runtime.
699 yaz-ziffy is no longer part of YAZ. It is distributed separately by
700 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
702 Changed license of CCL module to 'Revised BSD'. After consultation with
703 remaining members of the original EUROPAGATE consortium, we are re-issuing
704 the CCL module without a separate license. The software was developed by
705 Index Data as part of a research project. The special license was included
706 to help feed usage information back to the project consortium to support
707 project evaluation. At this time, the project consortium has long-since
708 disbanded, and the majority of the original principals have retired. At the
709 same time, we have significantly modified the software during the following
710 years, to the point where very practically no original code remains. To
711 simplify re-use of the software, we have contacted those members of the
712 consortium who could be reached, and agreed to re-issue the module as a
713 proper part of the YAZ package.
715 Tcl scripts uses /usr/bin/tclsh as preferred shell.
717 CQL closer to being version 1.2 compliant. CQL also allows free-form
718 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
721 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
722 bug could make Extended services handling crash in the ZOOM layer. This
723 bug was only present in YAZ 3.0.18.
725 --- 3.0.18 2007/12/19
727 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
730 yaz-marcdump reads and writes collection wrapped records.
732 Handle OPAC for record conversion module.
734 Fixes for ICU wrapper.
736 Allow ICU libs to be controlled with --with-icu .
738 --- 3.0.16 2007/11/12
740 Added yaz_poll which is a wrapper for select/poll. When poll is available
741 and non-buggy, it is used, by yaz_poll . This allows more than 1024
742 sockets to be in use.
744 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
745 functionality through an XML based configuration (ICU chain). This system
746 is useful for search facilities such as Pazpar2 and Zebra that needs to
747 perform tokenization of indexed material. The ICU code in a separate
748 library libyaz3_icu.a.
750 Added HTTP tunnel facility for COMSTACK, bug #1752.
751 This is a facility that allows a Web proxy, such as squid, to tunnel
752 Z39.50 traffic. This facility is "transparent" to must applications
753 using YAZ. It's enabled by using pseudo transport connect: followed by
754 the proxy address, followed by command, then follwed by he regular
755 "virtual" addresss. For example,
756 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
758 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
760 --- 3.0.14 2007/09/21
762 Fixed bad memory reference in ZOOM_record - cuased by member not being
763 initialized. This was a problem only in YAZ 3.0.12.
765 Fixed bug in conversion from MARC to XML: Non-XML characters in control
766 fields were not removed.
768 Changed the way C code is generated from codetables.xml. Made a MARC-8
769 conversion trie for each characterSet section rather than codeTable.
770 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
771 of codetables.xml from Larry Dixson, LOC. Bug #1464.
773 --- 3.0.12 2007/09/12
775 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
776 from ZOOM_record_error).
778 ZOOM C function ZOOM_record_get returns record schema for type="schema".
780 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
782 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
784 Better SRW-to-Bib-1 diagnostic mapping.
786 ZOOM C and yaz-client announces SRU version 1.2 by default.
788 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
791 Fixed in yaz_sru_decode to allow other version than 1.1.
793 --- 3.0.10 2007/08/22
795 Added support for SRU scan for ZOOM.
797 Added support for the use of the older versions or Extended Service
798 Update in ZOOM. To faciliate this, an option "updateVersion" may be
799 set to the version , 1=first, 2=second, 3=third. The third version is
800 what ZOOM C has used so far. And that, obviously, is the default.
802 Added support for CCL queries in Z39.50 queries sent to the GFS (and
803 therefore in Zebra and in SimpleServer-based applications). The new
804 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
805 qualifier file used to transform incoming CCL queries into Type-1 RPN,
806 which is passed into the back-end search callback function.
808 Added support for HTTP Basic authentication in clients: the SRU/W
809 codec encodes the username/password elements of the PDU structure
810 appropriately, and these may be set using the "user" and "password"
811 options in ZOOM-C applications (the same options that are used for
812 Z39.50 authentication).
816 Fixed bug #1208: SSL appears to be broken in ZOOM.
818 Fixed bug #1206: Libxml2 include path weirdness.
820 Added oid_name_to_dotstring.
822 Allow elementSetName to be specified for ZOOM C record update.
824 Allow waitAction to be specified for ZOOM C based for Extended Services.
826 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
827 syntax OID. Bug introduced in YAZ 3 series.
829 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
833 Fixed bug #1157: yaz-client does not read .yazclientrc from current
834 directory. yaz-client now reads commands from file given by option -f
835 if specified; then tries to read .yazclientrc in current directory.
836 Failing that, it reads .yazclientrc from user's home directory.
838 Added support for correlationInfo Note and ID for Record Update via
841 Added yaz-client command querycharset which specifies character set for
842 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
843 (termListAndStartPoint).
845 Charset ISO5428:1984 is an alias for ISO5428-1984.
847 Implemented a way to perform scan in a result set using Z39.50. This
848 is achieved by attaching the result set name in the characterInfo
849 (type InternationalString) of OtherInformation in the Scan Request PDU.
850 The result set is identified in the otherinformation by the new OID:
851 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
852 This allows for scan in result set and faceted search . Zebra did some
853 of this in the APT term using attribute type 8 and value being result
854 set. Using the OtherInformation approach for this is cleaner and easier
855 to work with in proxies and the like. This facility can be used in
856 yaz-client using new command setscan which takes a result set as first
857 argument, start position (APT) as second.
859 Changed decoding of SRU XML packed records to deal with servers that
860 have recordData with XML data with multiple root nodes. Also make
861 comparison for recordPacking case insensitive. Again, one server
862 returns "XML" where others return "xml".
864 For SRU responses allow Content-Type application/xml as well as text/xml.
868 Fixed bug in character set conversion of BER strings. Bug introduced
873 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
875 For OID class, use oid_class consistently.
877 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
880 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
881 character set for bibliographic information interchange". By Giannis Kosmas.
883 Added documentation on new OID API.
887 Changes to generic frontend server interface: added new member
888 'query_charset' for bend_initrequest structure. A backend init handler
889 should set this member to its native character set for query terms.
890 When defined, the frontend server logic will announce this character set
891 to a client if the negotiationModel bit is set by the client. All server
892 implementors are encouraged to specify this. If a backend server does not
893 specify this a warning is issued using yaz_log(YLOG_WARN,..).
895 Added CCL utility to remove terms (stop words) from resulting RPN
896 tree. This is handled by functions with prefix ccl_stop_words_ .
898 New ZOOM C option, "rpnCharset", which allows client-side conversion of
899 terms in RPN queries.
901 Clean-up the CCL API. Moved some internal structures from ccl.h to
902 private header cclp.h. Changed ccl_parser_create so that a Bibset must
903 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
904 This is replaced by ccl_parser_find_str which takes a string instead.
906 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
907 libyaz.la is the core of YAZ except the generic frontend server and
908 does not depend on POSIX threads anymore. libyaz_server.la is the
909 generic frontend server facilities and uses POSIX thread functionality
910 if available. The libyaz.la no longer depends on POSIX threads because
911 the number of global structures is limited. NMEM no longer re-uses blocks
912 between threads ; it simply free's memory immediately but allocates in
913 "large" chunks as usual. We don't expect any performance penalties
914 because of this. The yaz_log system is still using a global log_level so
915 caution must be taken when modifying it with yaz_log_init_.. +
916 yaz_log_mask_str. This, however, should not cause any trouble because
917 these functions are called during initialization of application code
918 anyway. `yaz-config --libs server` returns libs for server applications;
919 `yaz-config --libs` returns libs for non-server applications.
921 New OID database - with public definitions in oid_db.h. Removed old OID
922 database including the head oid.h and definitions such as enum oid_value
923 and struct oident. The new OID database uses the same string names as
924 before but the 'protocol' is gone. There are now only two representations
925 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
926 converts from string to OID; functions with prefix yaz_oid_to_string
927 converts the other way.
929 Change to emit_term() in CQL-to-PQF query translation: when a term has
930 the /regexp relation modifier, do not process it for leading and
931 trailing "^" and "*", which have quite different meanings in regular
934 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
935 write handlers no longer carries a 'last' parameter. This will make
936 yaz_iconv flush "less" characters. A flush is performed by call to
937 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
939 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
940 removed, because function yaz_query_to_wrbuf does the same.
942 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
943 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
945 Deprecated MARC utility functions removed.
947 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
950 Branch split: YAZ_2_1_55_branch
952 --- 2.1.54 2007/03/16
954 Fix to ZOOM-C so that transparent reconnection is properly handled on
955 connections that are in asynchronous mode.
957 Fixed compilation on OpenBSD 4.0.
959 Large strings in GRS-1 records are now properly displayed in yaz-client.
961 Added character conversion support for "advancegreek"; based on patch from
964 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
965 sequence is met. Before the error was not set so it would be unknown.
967 Adjust yaz-marcdump MARC reader so that it skips until record separator
970 --- 2.1.52 2007/03/07
972 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
973 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
974 fd_set structure used as a bitmask for the FDs to be selected on.
976 Using ACX_PTHREAD macro to check for POSIX threads.
978 Fixed have-vsnprintf check.
980 --- 2.1.50 2007/02/23
982 Fixes for configure on BSD. Bug #900.
984 Added snprintf/vsnprintf wrappers for systems that don't have
985 limits (heavens forbid).
987 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
988 created before all previous tasks were completed and removed from the
989 task queue, the new task could be removed by a mistake.
991 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
993 Implemented pass-through CQL-to-PQF conversions. Bug #861.
995 Fixed bug #832: Problem with MARC/charset in yaz-client.
997 Fixed bug #668: save command line history for yaz-client.
999 Fixed bug #830: pkg-config support.
1001 --- 2.1.48 2007/01/23
1003 Extended ZOOM result set options with two options that may be read by
1004 a client: resultSetStatus and presentStatus with values as specified for
1006 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1008 Fixed bug #827: Using SSL fails on Debian etch.
1010 Fixed bug #826: Weird looking chars for set of MARC records.
1012 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1013 that is treated as an ItemOrder with itemRequest being an XML document
1014 external. The value of "doc" is the content.
1016 Extended the GFS search facility. New member of bend_search_rr
1017 'estimated_hit_count' signals that hits is known to be an estmate
1018 (higher or lower than real hit count). New member 'partial_resultset'
1019 signals that the search was partial (hit count is lower or equal than
1020 real hit count). For Z39.50, the information is stored in resultSetStatus
1021 member of SearchResponse APDU. For SRU, the information is signalled
1022 via SRU diagnostic 59: "Result set created with valid partial results
1025 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1027 --- 2.1.46 2007/01/13
1029 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1031 Added ZOOM_connection_peek_event.
1033 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1034 the following new functions:
1035 ZOOM_event_nonblock, ZOOM_connection_process,
1036 ZOOM_connection_get_{socket,mask,timeout},
1037 ZOOM_connection_fire_event_{timeout,socket}.
1038 The existing blocking event handler, ZOOM_event, is a wrapper for the
1039 + blocking ZOOM_event_sys_{poll,select}.
1041 Implemented function ccl_xml_config which parses XML version of CCL
1042 configuration (bug #798).
1044 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1046 Added timings utility (yaz/timing.h)
1048 --- 2.1.44 2007/01/03
1050 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1053 Fixed bug #779: Rotation of apdu.log fails.
1055 Fixed for character set conversions:
1056 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1057 Honor G1 set in MARC-8 decoding.
1059 --- 2.1.42 2006/12/17
1061 Fixed bug #775: char conversion does not handle Alternative UTF-8
1064 Implemented function yaz_marc_read_line which parses MARC line format
1065 records. There is a wealth of formats out there. So far, this function
1066 reads line records produced by yaz_marc_write_line.
1068 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1069 more generic and easier to remember(!) options: -i format and -o format
1070 which specifies input format and output format respectively - where
1071 format is one of "marc", "marcxml", "line", "marcxchange".
1073 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1074 does not print anything except warnings for records.
1076 For yaz-marcdump, added support for MARC split into files (-s) with a given
1079 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1080 spec, at http://www.loc.gov/standards/sru/record-update/
1081 This has changed the binary layout of the following structs:
1082 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1083 bend_update_rr . Patch by Ko van der Sloot.
1085 Added GFS utility function bend_assoc_is_alive which returns 1 if
1086 association is still alive (client is connected); 0 otherwise (client
1087 closed connection). This allows busy servers to stop working for
1090 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1091 been a separate piece of software. This version of ziffy has been modified
1092 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1094 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1096 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1097 Client code may now interrogate options such as "init_opt_sort" to
1098 find out whether the server claims to support various options.
1100 --- 2.1.40 2006/11/27
1102 Added utilities yaz_{set,get}_esn to set/get element set name from
1105 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1106 of YAZ and has been so since YAZ 2.1.10.
1108 Implemented ZOOM_record_error which returns error information for
1109 record (surrogate diagnostic).
1111 --- 2.1.38 2006/10/31
1113 Updates for SRU Update by Ko van der Sloot:
1114 1. Changed name from "operation" to "action"
1115 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1116 versions in the code, marked as 'backward compatible'.
1117 3. Added diagnostics for SRU Update.
1119 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1121 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1123 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1125 For GFS, fixed problem with SRU diagnostic 'First record position out of
1126 range' being issued for 0 hits.
1128 zoomtst10 part of Windows Build.
1130 --- 2.1.36 2006/10/13
1132 Implemented yaz_filepath_comp which splits a path into file path
1133 components (required by Zebra 2.0.3+).
1135 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1136 BSD inspired license until now so this should not have any real impact on
1137 anybody. See http://www.opensource.org/licenses/bsd-license.php
1139 Fixed bug #687: Missing log lines.
1141 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1144 Fixed bug #689: SRU diagnostics to be added.
1146 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1147 whether a connection is idle (no more work do do).
1149 --- 2.1.34 2006/10/04
1151 Change type of optval from long to int for invocation of setsockopt with
1152 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1154 Added support for specifying the max log file size for the Generic
1155 Frontend Server. The size is given with option -r.
1157 --- 2.1.32 2006/09/21
1159 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1161 --- 2.1.30 2006/09/17
1163 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1166 Fixed bug in Generic Frontend Server that could cause a server to stop
1167 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1169 For the generic frontend server, the maximum record size is used as maximum
1170 size of incoming packages (SRU + Z39.50). The value until was previously
1171 only used in Z39.50 Init negotiation and, later, in a session controlled
1172 sizes of records returned. This is controlled using -k option. It can be
1173 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1175 --- 2.1.28 2006/09/04
1177 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1180 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1182 New option for yaz-marcdump -lpos=value which allows setting a portion
1183 of MARC header to a certain value.
1185 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1187 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1188 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1190 --- 2.1.26 2006/08/15
1192 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1195 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1197 --- 2.1.24 2006/08/08
1199 Fixed MARC ISO2709 encoding routines to deal with character set
1202 Minor changes to GFS logging. Database included in search request log
1205 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1206 cached/multiple records.
1208 Shared libraries are built by default on Unix+configure.
1210 Changed cql2pqf transformation to use a different evaluation order. The
1211 new order is: always, relation, structure, position, truncation, index
1212 and relationModifier. Old order was: always, relation, relationModifier,
1213 structure, index, position, truncation. Note that the the latter ones
1214 override former ones for identical attributes.. The new scheme means that
1215 it is possible to override any existing attribute with a relationModifier.
1216 And also that it is possible to override everything for the index rule
1217 (except the ones listed in relationModifier). No order is perfect but this
1218 one, we believe, covers more real cases.. The "always" should have been
1219 called "default", since the attributes there can be overridden with all
1222 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1223 compilation phase, but also for yaz-config --cflags output. This allows
1224 us to have public headers with Libxml2 stuff in them . It should also,
1225 eventually, make Libxml2 checks redundant in packages using YAZ, such
1228 --- 2.1.22 2006/06/15
1230 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1231 stored in uri, message and details.. Previously diagnostics were stored
1232 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1233 compatibility.. but he's probably the only one affected, so.
1235 Added support for CCL, compiled on the client side, in ZOOM-C. This
1236 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1237 input; the resulting query objects can be used for for searching with
1238 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1240 YAZ' configure searches for OpenSSL by default.
1242 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1243 SL_CTX_use_certificate_file. See
1244 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1245 for more info. Thanks to Ko van der Sloot.
1247 --- 2.1.20 2006/06/02
1249 Bug #600: SRU GET, POST support for yaz-client. Introduced
1250 command 'sru' which selects method SOAP/GET/POST.
1252 Allow missingValueAction to be specified for the sortspec string -
1253 function yaz_sort_spec. By default, the missing value action is null.
1254 Use ! to specify "abort". Use = followed by stringvalue to specify default
1257 Ensured that Present-handler (if defined) is called in GFS before any call to
1258 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1259 searchRetrieve requests.
1261 Documentation for YAZ is now based on the Docbook XML/XSLT using
1262 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1263 is no longer depending on jade/openjade or docbook-to-man scripts.
1264 PDF is no longer part of the distribution - but can optionally be
1265 made using DSSSL/jadetex or FOP.
1267 Added retrieval handling support in Generic Frontend Server to support
1268 conversion between MARC/XML as well as XSLTtransforms. See
1269 etc/yazgfs.xml for an example.
1271 Added Authentication support to Generic Frontend Server in SRU
1272 mode. Authentication using HTTP Basic is supported, as is the use
1273 of 'x-username' and 'x-password' parameters in the request itself.
1275 Added support for a new character set MARC8s identical to MARC8 except
1276 that it converts combined characters to single Unicode characters in the
1277 Latin-1 range (when possible).
1279 --- 2.1.18 2006/04/24
1281 ASN.1 compiler 0.4: generates brief Doxygen file header for
1282 generated .h/.c files.
1284 Utility yaz_iconv now supports conversion to MARC-8.
1286 New facilities for the MARC module. The reading - and writing of
1287 content are separate methods for the yaz_marc_t handle. The following
1288 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1289 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1290 format). Write functions have prefix yaz_marc_write_.. The existing
1291 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1292 available. Removed support for OAI-MARC and simplexml (not the
1293 simplexml from PHP5).
1295 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1296 to be returned for this connection.
1298 --- 2.1.16 2006/03/31
1300 Allow multiple languages and charsets to be specified with
1301 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1302 negcharset iso-8859-1,utf-8
1304 Translation of proximity nodes from CQL into PQF now works.
1306 Moved to automake 1.8, 1.9.
1308 Added function yaz_log_set_handler which allows a log handler to be
1309 installed. This handler will be called for all log messages. Output
1310 to file is also produced; but that can be disabled by passing NULL
1311 fname to yaz_log_init_file.
1313 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1315 For SRW (including GFS), accept application/soap+xml as content-type
1318 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1319 produces NO stylesheet reference even if a default stylesheet is specified
1322 --- 2.1.14 2006/03/14
1324 Updated Windows package to include yazd.dll + yazd.lib for the
1325 Development component.
1327 If the environment variable YAZ_LOG is set, then it is used as a
1328 string indicating the default level of logging to use if not
1329 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1330 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1331 used as before. So, for example, to omit warnings from YAZ logging,
1332 export YAZ_LOG=-warn
1334 cql_transform() now map structure and other attributes before indexes,
1335 so that index-specific structures and other attributes can override
1336 defaults. So now a combination of mapping specifications such as:
1338 index.dc.date = 1=date-modified 4=5
1339 does the right thing.
1341 cql_transform() now also respects the "always" mapping specification,
1342 which establishes an initial set of attributes to be used for all
1343 terms except where overridden by more specific attributes associated
1344 with the index, relation or modifier.
1346 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1347 which mode to use; one of "post", "get" or "soap" (SRW, default).
1349 Fixes for yaz_iconv routines: changed trie-based character set conversions
1350 to use only non-negative values for bit fields due to Sun's C compiler not
1351 supporting negative values.
1353 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1354 sequences where not read correctly. Fix by Rustam Usmanov.
1356 Updated win/makefile to use options, settings which makes things
1357 compile with VS C 2005.
1359 --- 2.1.12 2006/02/01
1361 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1363 In ZOOM socket code, use select instead of poll on MacOSX.
1365 ZOOM-C now support client-side compilation of CQL into RPN that is
1366 sent to the server, enabling CQL to be used against all Z39.50
1367 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1368 ZOOM_query object, and submit it using ZOOM_connection_search().
1369 The CQL-to-RPN translation uses a configuration file, the name of
1370 which must be specified in the Connection's "cqlfile" option.
1372 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1373 function, which takes as its start-term parameter a ZOOM_query object
1374 (which may have had either CQL or RPN set into it).
1377 --- 2.1.10 2005/11/29
1379 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1380 GFS to support this as well. Backend handler, bend_srw_update, does the
1381 update work. Code contributed by Ko van der Sloot.
1383 Allow retrieval of Search Result-1 information in ZOOM by the use of
1384 options that are attached to a result set. ZOOM documentation updated
1387 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1388 UTF-8 conversion. Patch by Raj Patel.
1390 Added option -m to GFS to control formatting of timestamps in log file.
1392 Added 'exit' as synonym for 'quit' in yaz-client
1394 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1395 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1396 for the new members. Patch by Ko van der Sloot.
1398 Added support for SRU POST. It is supported for content-type
1399 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1401 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1402 Instead make the library libyaz.la multi-threaded. Threading as a whole
1403 can still be disabled by configure option --disable-threads. Previosly,
1404 with older GLIBCs there were problems with MT libs under Apache. This
1405 has now been fixed a long time ago.
1407 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1410 CQL module modified to be case insensitive for relations/indexes/operations.
1412 Fixed bug in CQL transform code: incorrect value relationModifieder
1415 Added 'show all' command for yaz-client which retrieves all results
1418 Added new yaz-client, xmles, which takes a (private) OID and
1419 a document to be sent as an extended service request.
1421 Describe new yaz-client commands wait_response and set_auto_wait.
1423 Increase TCP/IP listener backlog from 3 (which I am guessing was
1424 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1425 that the socket will queue as many incoming connections as it's able
1426 to handle ongoing connections. In other words, it will never now
1427 refuse a connection that it would be able to handle merely because
1428 it's not got around to accepting() enough of the pending connections
1429 yet. This is the behaviour anyway under Linux, where the listen()
1430 argument is ignored; but not under BSD and on systems such as
1431 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1432 YAZ-based servers should now be uniform across operating systems in
1435 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1436 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1437 This allows yaz-marcdump to read large MARC batches (>2 GB).
1439 Modified all YAZ source files - except the source which is auto-generated
1440 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1443 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1444 corresponding to the existing *_setl() function. These allow option
1445 values containing arbitrary valuues.
1447 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1448 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1449 except that it returns an indicator of whether or not the sort
1450 criterion was accepted (0 for OK, -1 for invalid).
1452 --- 2.1.8 2005/06/07
1454 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1455 MARC output rather than returning "new" buffer.
1457 yaz-client warns about unknown init options.
1459 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1461 --- 2.1.6 2005/05/24
1463 Added support for SRW sort in Generic Frontend Server. Patch
1464 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1465 sortKeys - or NULL if none is provided.
1467 Fixed bug #307: It was impossible to specify indefinite/no timeout
1468 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1471 Added support for multiple languages and charsets to be specified in
1472 ZOOM. Each charset/language is separated by a blank. If negotiation is
1473 in effect in init-response, Option
1474 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1475 Code based on patch by Vasiliy Osadchuk.
1477 Fixed bug #306: infinite recursion that occurred when calling
1478 yaz_log_level_init as the first call (before other log level or
1481 Fixed bug in scan handling in front end server: if preferred-Position-In-
1482 Response was non-present, a NULL pointer referece was performed.
1484 --- 2.1.4 2005/04/26
1486 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1487 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1488 now defined for all those error codes. So instead of putting 109 in
1489 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1490 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1492 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1495 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1497 Program yaz-client now exits and produces an error message if multiple
1498 Z39.50 servers are specified on the command line (none or one allowed
1501 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1504 --- 2.1.2 2005/03/16
1506 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1508 Fixed bug #272: Preserve spacing for CCL terms.
1510 --- 2.1.0 2005/03/14
1512 Added support for virtual hosts and multiple backend servers for
1513 the YAZ frontend server. The configution is XML based and
1514 support specificition of CQL to RPN mappings and explain information.
1515 See section "Virtual Hosts" in the YAZ manual.
1517 Extended OPAC display utility. OPAC display utility renders
1518 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1519 to supplement yaz_marc_decode_wrbuf.
1521 Fixed a bug in MARC decoder that could caused it to crash for some
1522 invalid MARC records. More diagnostics and warnings where added in
1523 XML output (warnings, etc are stored in comments).
1525 --- 2.0.34 2005/02/08
1527 Fixes for UNIX domain sockets. Bug #261.
1529 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1531 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1532 Added yaz_marc_subfield_str which defines subfield lead string which is
1533 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1534 yaz_marc_endline_str which defines end of fields string used in
1535 YAZ_MARC_LINE format. Default string is newline.
1537 Experimental support for MarcXChange. This format can be produced
1538 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1539 http://www.bs.dk/standards/MarcXchange.xsd
1541 Added yaz-client commands scansize that sets maximum number of
1542 entries to be returned by scan.
1544 --- 2.0.32 2005/01/11
1546 Added support for SRW scan in yaz-client and Generic Frontend Server.
1548 * Added whereInList member to SRW Scan Term.
1550 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1552 Fixed NMEM system to return aligned blocks on the smallest boundaries
1553 that are suitably aligned for all possible types on the particular
1554 architecture YAZ is being built for.
1556 --- 2.0.30 2005/01/04
1558 Fixed numerious warnings that was issued with newer versions of GCC.
1560 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1561 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1564 Make YAZ Generic Frontend Server slightly faster.
1566 Enhance (and reduce) logging for Generic Frontend Server.
1568 Revert YAZ log system so that it flushes every write operation
1569 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1571 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1572 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1573 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1574 will effectively disable old definitions.
1576 --- 2.0.28 2004/11/09
1578 Added yaz_log_time_format which specifies log format using
1581 Added yaz_log_module_level which returns mask for a module. Value
1582 is non-zero mask a if module is enabled; zero if disabled.
1584 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1585 in include/yaz/cql.h.
1587 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1589 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1591 Fixed bug #172: RPM builds does not enable SSL.
1593 Doxyfile.in part of dist. Doxyfile generated by configure.
1595 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1596 are given and the corresponding component does not exist.
1598 Extend CCL documentation in YAZ reference. Describe r=r.
1600 --- 2.0.26 2004/10/01
1602 Fixed MARC->MARCXML conversion to properly deal with
1603 fields, subfields, indicators having non-ASCII characters.
1605 Fixed MARC->MARCXML conversion so that ASCII control characters
1606 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1609 Added YAZ GFS support for conversion from Z39.50 surrogate
1610 diagnostics to SRW surrogate diagnostics.
1612 Bug fix: YAZ GFS did not return schema in explainResponse.
1614 --- 2.0.25 2004/09/30
1616 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1617 now converts recordSchema to elementSetName as well as schema URI.
1619 Fixed bug in COMSTACK that prevented HTTP request packages from being
1622 --- 2.0.24 2004/09/29
1624 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1625 does not require white-space before and after the dash in a range, e.g.
1626 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1629 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1630 due to new GCC removing "redundant" code.
1632 Added yaz-client commands scanpos and scanstep that sets preferred
1633 position and step-size for scan.
1635 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1637 Added CCL utility ccl_qual_buf which parses one or more CCL
1638 spec lines in a buffer.
1640 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1641 of name and value - ignoring empty lines and comments.
1643 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1645 Added odr_get_element_path which returns current element path for an
1646 ODR handle. This utility is useful in error handling or user-defined
1649 Added ODR_PRINT utility odr_set_stream which is is a more generic
1650 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1651 to a write function and pointer to close function. The close function - if
1652 non-NULL - will be called during odr_destroy.
1654 Fixed bug in CCL parser where truncation char was not removed from
1655 right side when truncation=both was in effect.
1657 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1660 --- 2.0.23 2004/08/11
1662 Fix buffer overrun in CQL parser when dealing with proximity (%).
1664 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1665 to UTF-8/UCS conversion is now only based on codetables.xml.
1667 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1669 --- 2.0.22 2004/08/06
1671 Add support for more "commit changes" in ZOOM (uses Extended Services).
1673 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1676 Yet another small fix for configure of SSL.
1678 --- 2.0.21 2004/05/14
1680 Fix SSL libs for configure when --with-openssl=DIR is given.
1682 --- 2.0.20 2004/05/10
1684 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1686 SSL comstack now uses yaz.pem certificate file on server side
1687 by default. Certificate filename can be configured by calling
1688 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1690 Fix bug regarding multiple calls to ZOOM_connection_connect.
1692 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1694 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1695 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1697 ZOOM now allows inspection of X509 peer certificate for verification.
1698 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1700 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1701 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1702 as "modular" but it simplifies things.
1704 Added cs_get_peer_certificate to that returns peer X509 PEM.
1706 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1707 NULL if SSL is unavailable.
1709 Documentation about MARC decoding tools.
1711 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1713 --- 2.0.19 2004/03/30
1715 Rename CHANGELOG to NEWS to follow GNU style packing.
1717 Fix bug with missing initialization of member in init_diagnostics.
1718 This bug affects threaded version of GFS server.
1720 --- 2.0.18 2004/03/20
1722 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1725 Ensure zlib.dll is packed with Windows install.
1727 --- 2.0.17 2004/03/17
1729 Fix encoding of xsd:string to use text instead of CDATA.
1731 Fix endless loop in CQL parser with unbalanced ".
1733 Use a more compact way to store MARC-8 conversion tables.
1735 --- 2.0.16 2004/03/16 Debian only
1737 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1740 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1745 --- 2.0.15 2004/03/01
1747 Another fix for decoding of XML packed records.
1749 --- 2.0.14 2004/02/25
1751 Fixes for Chunked encoding. White space not ignored after length spec.
1753 Update NS and use default NS for SRW diagnostic elements.
1755 --- 2.0.13 2004/02/23
1757 Implement ZOOM_resultset_cache_reset which resets record cache.
1759 Implement ZOOM_resultset_sort which sorts a result set.
1761 Implement chunked HTTP transfer.
1763 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1765 --- 2.0.12 2004/02/16
1767 Added member 'schema' to bend_explain_rr structure so that backend
1768 can specify explain record identifier. Defaults to Zeerex 2.0.
1770 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1772 --- 2.0.11 2004/02/16
1774 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1777 Added init command for yaz-client which sends "extra" init request.
1779 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1780 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1782 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1784 Make ZOOM error code for "invalid query".
1786 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1788 --- 2.0.10 2004/02/05
1790 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1793 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1795 Added option -p <file> to make Generic Frontend Server to write PID file.
1797 Added option -D to put Generic Frontend Server in background on its own.
1799 Make ZOOM C recognize option "password". If unset, "pass" is used
1800 (for backwards compatibility).
1802 Fixed a bug in Generic Frontend Server that could make it crash if a
1803 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1806 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1807 Must be issued before open, in order to be in effect.
1809 --- 2.0.9-6 2004/01/12 Debian/Windows
1811 Make the SRU server more picky WRT unknown params, etc.
1813 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1815 New YAZ client command, options, that sets Z39.50 options.
1817 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1818 options from a string of tokens (one token for each option bit).
1820 Update SRW diagnostic code messages.
1822 --- 2.0.9-5 2004/01/07 Debian/Windows
1824 Handle user defined stylesheet for SRW/SRU.
1826 --- 2.0.9-4 2004/01/06 Debian/Windows
1828 Fix bug in decoding of Content-Length.
1830 --- 2.0.9-3 2004/01/06 Debian/Windows
1832 Fix a bug with decoding of XML packed records.
1834 --- 2.0.9-2 2004/01/05 Debian only
1836 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1838 Fix bug in SRW/SRU diagnostics decoding.
1840 --- 2.0.9 2004/01/05
1842 Fixed bug in Generic Frontend Server which could drop records exceeding
1843 preferred message size. Reported and fixed by Irina Dijour.
1845 Fixed calculation of package size for structured records in Generic
1846 Frontend Server. Reported and fixed by Irina Dijour.
1848 Fixed namespace for SRW/SRU diagnostics.
1850 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1852 --- 2.0.8 2003/12/22
1854 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1855 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1858 CQL changes to reflect recent changes to the specification:
1859 * Documentation talks about context sets instead of index sets.
1860 * Documentation talks about indexes instead of qualifiers.
1861 * The CQL-to-PQF transformer's configuration file now uses
1862 "index.set.name = <attributes>" instead of the old form
1863 "qualifier.set.name = <attributes>". (Both forms are still
1864 understood but the latter is deprecated.)
1865 * CQL terms with no explicit index specified are now interpreted as
1866 cql.serverChoice instead of srw.serverChoice (which of course
1867 behaves exactly the same.)
1869 --- 2.0.7 2003/12/16
1871 MARC conversion can now generate ISO2709 output in another
1872 character set. yaz-marcdump uses this facility if you invoke it
1875 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1876 functions from there can be used from C++.
1878 --- 2.0.6 2003/12/04
1880 Frontend server now transfers memory from decoded packages to stream
1883 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1884 references to show up.
1886 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1887 the ZOOM Abstract API. The older names for the same options are still
1888 also supported for the benefit of old applications.
1890 ZOOM-C supports "implementationId" and "implementationVersion" options
1891 to go along with "implementationName". These allow the user code to
1892 specify identification strings to be sent to servers.
1893 Add OID for the new ExtLite attribute set.
1895 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1896 as requested/supplid by Ere Maijala <ere@atp.fi>
1898 For generic frontend server, reverse the order of
1899 "toolkit-supplied / application-supplied" strings sent as implementationId,
1900 Name and Version. Also, remove the spaces around the slash. This brings
1901 the GFS in line with the behaviour of ZOOM-C on the client side.
1903 Add function ZOOM_scanset_display_term.
1905 yaz-client shows scan displayTerm if present.
1907 Utility yaz-iconv is now installed by default along with the man page
1910 Extend configure check for OpenSSL to use pkg-config where available (such
1913 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1914 server to specify uid/gid/mask for socket using the format
1915 unix:[user=uid,][group=gid,][umask=mask,]file=path
1916 If file= is omitted the existing format is assumed, e.g.
1918 in which case the mask is 0666 (rw for everybody).
1920 Major restructure of YAZ source. All source in libyaz is in src directory.
1921 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1922 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1924 Added man page for utility yaz-marcdump (used to be called marcdump).
1925 yaz-marcdump is installed by 'make install'.
1927 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1928 of incoming package failed.
1930 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1932 Change prototype of odr_perror: add const to message string.
1934 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1936 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1937 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1938 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1939 DNS lookup. There should not be any compatibility problems with this
1940 assuming that blocking=1 or 0 is used.
1942 Fix bad reference in UNIX comstack in function cs_addrstr.
1944 Fix for compilation on AIX.
1946 The generic front-end server (server/seshigh.c) now supports returning
1947 Init diagnostics to the client in User-information-field, in
1948 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1951 --- 2.0.4 2003/09/04
1953 Allow any CQL relation (not just all,any,exact,scr).
1955 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1956 that features the same UI.
1958 Implemented command update0 in YAZ client which is equivalent to
1959 update but uses old of Ext Update ASN.1.
1961 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1962 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1963 Previously no OID was used for this info.
1965 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1966 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1967 returns 'malformed search term' otherwise.
1969 SortResponse member resultCount now set to NULL in sort handler of
1972 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1975 Add three new utility functions for translating OIDs between various
1976 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1977 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1978 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1979 char *oid_to_dotstring(const int *oid, char *oidbuf);
1980 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1982 Reverted modifications for ES Update definition for z_IU0Update
1983 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1984 is back to YAZ 2.0.2.
1986 String value attributes for CCL parser.
1988 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1989 which their FirstSearch server returns in Init responses, sometimes
1990 carrying useful diagnostic information when Init fails. This has the
1991 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1992 "z39.50/oclcui.asn", where its definition is somewhat different from
1993 what OCLC document on their web-site, as required to interoperate with
1996 Support for anonymous authentication in yaz-client. Use the command
1999 * Fix the OID of the Index Data-local "admin" Extended Service from
2000 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2001 the 1000, which indicates a locally-defined OID, was a mistake.
2003 --- 2.0.3 2003/06/20
2005 Fix CCL directive @case handling so that it affects string match for
2006 both CCL keywords and qualifiers.
2008 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2009 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2010 Decoder has been updated with ASN.1 changes as listed in
2011 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2012 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2013 z_IUUpdate, remains unchanged.
2015 ZOOM_record_get may now return a record in a specific character set.
2016 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2017 "from" is the character set of record as returned by target. "to" is
2018 the character set to be returned. If omitted, "to" is UTF-8.
2020 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2022 New ODR utility, odr_getelement, which returns name of element for
2023 which encoding/decoding failed.
2025 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2026 in cases where a required element was omitted.
2028 Bug fix: some MARC8 sequences were not converted.
2030 New ZOOM option "step" which specifies number of records to be
2031 retrieved in one chunk. Used in conjunction with "start" and "count".
2033 SRW support for yaz-client. Use scheme http: to use it, e.g.
2036 yaz-client no longer does (un)intelligent character set conversions
2037 by default. Can be enabled with charset and marc_charset commands.
2039 xmalloc trace fix for 64-bit systems such as DEC alpha.
2041 Solaris 2.6 compile fix.
2043 New function, cql_strerror() translates SRW error codes, as returned
2044 by cql_transform_error(), into human-readable English strings. Used
2045 in yaz-client diagnostics when appropriate.
2047 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2048 converts it into a type-1 query which is sent to the server. This
2049 makes CQL available for use with all Z-servers, as opposed to the tiny
2050 minority that can handle CQL queries themselves.
2052 --- 2.0.2 2003/04/28
2054 New Debian package layout similar to the Redhat Package layout.
2056 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2057 and search result respectively.
2059 --- 2.0.1 2003/04/25
2061 Redhat package is now several packages: libyaz (runtime libraries),
2062 libyaz-devel (development and documentation, and yaz (utility programs).
2063 Package spec file by Morten Bogeskov.
2065 New member 'schema' in struct bend_fetch_rr which the name of requested
2066 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2067 handler MAY set this to reflect the schema of the returned record.
2069 New member 'display_term' in struct scan_entry. GFS now sets member entries
2070 and allocates scan entries to be filled by user scan handler. In previous
2071 version, entries member was allocated by the scan handler. That still works,
2072 but the GFS will ignore member display_term - assuming it was NOT set by
2073 the handler. The fact that the GFS now allocates the entries both allows
2074 for new members and makes a scan handler easier to write.
2076 Fix CQL lex buffer overflow.
2078 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2079 SRU default recordPacking is string.
2081 SRU protocol support for frontend server.
2083 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2085 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2087 Added scan for the ZOOM shell (zoomsh).
2091 * String Identifers for Schemas (Amendment 5).
2092 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2093 Old definition for schema
2094 Odr_oid *schema; /* OPT */
2099 Z_InternationalString *uri;
2100 #define Z_Schema_oid 1
2101 #define Z_Schema_uri 2
2104 * resultCount parameter to Sort Response (Amendment 1).
2105 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2107 Support for SRW 1.0 over HTTP. This is an optional feature and
2108 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2111 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2112 on the same port. SRW SearchRetrieveRequests are mapped
2113 to bend_init,bend_search,bend_fetch,bend_close.
2115 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2117 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2118 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2120 ZOOM connections are SRW based if schem http is used for hostname
2121 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2122 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2124 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2125 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2126 distance=n, order=true/false, relation=le, prox unit=word. If
2127 n is omitted, distance 1 is used.
2129 Fixed problem with C compiler include path in wrong order.
2131 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2132 on Solaris. Patch from Ko van der Sloot.
2134 New MARC decode API. All new functions operate on a yaz_marc_t
2135 handle. The most important new functions are: yaz_marc_create,
2136 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2137 decode and destroy respectively. Decoder can produce formats
2138 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2139 include/yaz/marcdisp.h.
2141 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2142 to UTF-8, UCS-32, wchar_t or Latin-1.
2144 * Prototypes for yaz_iconv_-functions moved to separate header
2145 include/yaz/yaz-iconv.h.
2147 Make a few private functions 'static' in unix.c. This prevents
2148 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2150 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2151 are set when Init Response is received.
2153 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2154 but returns diagnostic set as well.
2156 New function yaz_strerror which is a portable wrapper for
2157 strerror/strerror_r/GetLastMessage.
2159 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2160 is returned for MARC. If type is "oai", then OAI MARC is returned.
2162 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2165 --- 1.9.2 2002/11/26
2167 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2169 Fix bad race conditions on SIGTERM and terminate gracefully in
2172 Move retrieval (data1) module to Zebra since nobody seems to be
2175 Add GRS-1 render for ZOOM using same format as yaz-client.
2177 --- 1.9.1 2002/10/05
2179 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2181 Fix broken ESpec handling in data1 module.
2183 SGML reader parses comments and makes them part of the data1 tree.
2185 Added several type casts so that YAZ compiles as C++ code.
2187 ZOOM didn't handle PDU encoding failures properly.
2189 Added more Bib-1 diagnostics (approved extensions).
2191 GNU configure: better check for iconv.
2193 More portable use of accept, getpeername. Check for socklen_t. Use
2194 int/size_t if socklen_t is not defined.
2198 PQF parser rejects bad queries - including those with extra
2199 characters in them. PQF parser used to silently ignore that.
2200 Cleaner API for PQF added, which allows you to get detailed
2201 error information for bad queries (see yaz/pquery.h).
2203 Fixed bug in ZOOM_record_get for type "database".
2205 Implemented mini iconv library supporting conversions between
2206 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2208 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2210 --- 1.8.9 2002/08/20
2212 Fixed ZOOM C record cache so that preferredRecordSyntax and
2213 elementSetName is used to check for already fetched records.
2215 --- 1.8.8 2002/08/02
2217 Added three members in bend_initrequest structure to facilitate
2218 character set negotiation.
2220 Fixed a bug in frontend server that could cause indefinite
2221 loops under rare conditions.
2223 Revised character set utilities (charneg.h) so that encoding
2224 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2226 For PQF, directive @term <type> sets term type for Scan/Search.
2227 Here <type> is general, string, numeric, null. The term type
2228 is inherited - just like @attr.
2230 New call odr_set_charset that sets character set conversion for
2231 international-strings on a ODR stream. Prototype is:
2232 int odr_set_charset(ODR o, const char *to, const char *from);
2233 The InternationalString is still represented as C string in YAZ
2234 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2235 won't). On the protocol level, you can use any encoding.
2237 Support for UNIX sockets in ZOOM.
2239 Solaris recv sometimes returns errno == ENOENT. It is treated as
2240 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2242 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2243 both client and server. Code by Morten Bogeskov.
2245 --- 1.8.7 2002/05/22
2247 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2248 that they can be used directly from Visual Basic. You must recompile
2249 your windows APP if you're using ZOOM.
2251 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2252 Commands "lang" and "charset" sets language and character set respectively.
2253 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2254 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2256 Attributes from multiple CCL fields may be OR'ed rather than merged
2257 using directive "@field or". Fields are still merged by default -
2258 equivalent to "@field merge".
2260 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2263 Fixed bug in zget for parameter ExtendedServicesResponse.
2267 --- 1.8.6 2002/03/25
2269 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2271 Client displays USR.1:SearchResult-1 (hits per term).
2273 Additional Search Info for search in Generic Frontend Server.
2275 Fixed CCL parsing of "field=s".
2277 WIN32 installer - using the excellent NSIS software from nullsoft.
2279 Fixed CCL parsing of "field = - <number>".
2281 Added function yaz_marc_decode that decodes MARC for line mode
2282 display or XML (similar to that used by JZKit).
2284 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2285 Z39.50. But ISO/ILL was, however.
2287 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2288 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2290 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2291 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2293 --- 1.8.5 2002/02/03
2295 New YAZ client features: Command completion and new commands:
2296 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2297 Code provided by Jacob Poulsen.
2299 New call oid_trav, that visits all registered OIDs via callback.
2301 Function ZOOM_record_get now returns const char pointer rather than
2302 void pointer. It saves a lot of type casts.
2304 For YAZ client, command "auth" now allows you to set authentication
2305 in IdPass style. It is enabled when three tokens are given - order
2306 is user, group and password.
2308 Fix memory leaks in MARC record handling for ZOOM.
2310 New option for YAZ client, -k <kilobytes> that sets
2311 maximum record size. Similar to -k option for generic frontend
2312 server and yaz-ztest.
2314 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2316 Prefix query parser reports "fail" when bad attribute set is given.
2318 Fix in MARC decoder. Proximity logging. Fix for attribute set
2319 in scan handler for server. Patches by Shigeru Ishida.
2321 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2324 Configure option --with-openssl=<dir> now works when a directory is
2325 specified. Patch provided by Morten Bogeskov.
2327 New option for YAZ client, -u <auth>, that sets authentication.
2329 ZOOM fix: error information was sometimes "missing", since error
2330 was cleared/reset too when it shouldn't.
2332 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2334 --- 1.8.4 2002/01/04
2336 Scan for ZOOM API. New object ZOOM_scanset. New functions
2337 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2338 ZOOM_scanset_destroy.
2340 New ZOOM function, ZOOM_connection_last_event, that returns type
2341 of last event (such as "receive data", "send data", "apdu received",
2344 New ZOOM option, schema, that specifies schema for retrieval.
2346 New CCL feature. Qualifiers can be aliases for one or more
2347 other qualifiers (if more than one is given, OR is used).
2349 ZOOM uses named result sets if target supports it.
2351 Two new YAZ client commands: . (dot, which sources a script of YAZ
2352 client commands), and ! (to execute shell command.). Implemented
2355 Working on Debian packages.
2357 --- 1.8.3 2001/11/19
2359 YAZ client enables named result sets only if target supports it.
2361 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2363 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2364 with key="host" to get same result.
2366 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2367 Function Z3950_resultset_record(s) returns references to records
2368 "owned" by resultset. To become owner use Z3950_record_clone.
2370 Function z_ext_record handles Extended Services. Thanks to
2373 --- 1.8.2 2001/11/12
2375 CCL Parser fix: ignore token comma when dealing with and-lists.
2377 Documentation updates for COMSTACK.
2379 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2380 Changed prototype Z3950_records. For some functions, int parameters
2381 were changed to size_t.
2383 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2386 New MARC decode/display function, marc_display_exl, which properly rejects
2387 non-ISO2709 records. YAZ client uses it.
2389 --- 1.8.1 2001/10/29
2391 Fix bug: local attribute set wasn't set correctly in PQF strings.
2395 * Old Z39.50 codecs no longer supported.
2397 Added ZOOM C binding. See http://zoom.z3950.org/
2399 Renamed states for COMSTACKs to avoid confusion with events.
2401 Implemented cs_look and proper cs_rcvconnect.
2403 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2405 Configure detects POSIX threads on OpenBSD.
2407 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2408 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2410 When error is returned from present handler, non-surrogate diagnostic
2411 is returned in present response (and fetch handler is no longer called).
2413 * Minor adjustments to pquery parser (PQF). Token characters may be
2414 escaped by using backslash (C-style).
2416 PQF parser allows string attribute values to be specified. For @attr,
2417 non-numeric characters after the equal-sign are treated as strings
2418 (e.g. @attr 9=title).
2420 CCL trunction character may be defined (@truncation in file)
2422 * function zget_ExtendedServicesRequest sets waitAction to
2423 waitIfPossible (was wait).
2425 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2428 CCL operator names may be set in field definition files (CCL_bibset).
2429 See ccl/bib1 for an example.
2431 Fixes in ASN.1 compiler for C++ compatibility.
2433 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2434 and "op_or" to avoid conflict with C++.
2436 Fixed problem with GNU readline detection on Redhat 7.0.
2438 Added step-size for Scan backend handler.
2440 Fixed bug that made the frontend server crash when no attribute
2441 set was specified for scan.
2443 Front-end server automatically switches to original working directory
2444 when installed as an NT service. Previously -w had to be specified to
2447 Added extended attributes for retrieval module (data1), so that data1
2448 records carry d1_readXML/SGML attributes. d1_read also supports
2449 null-data rules ( <tag/>)
2451 On UNIX when POSIX threads are available, a separate library libyazthread
2452 is created. Programmers should link with that library and the yaz library
2453 when using threads. The reason for the split was that some applications
2454 on Linux, such as Apache, doesn't work well when using shared objects that
2457 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2458 (or any frontend server) in SSL mode by specifying ssl: followed by
2459 address. Only tested on UNIX.
2461 Added feature for CCL module. Virtual structure s=al or s=ol generates
2462 and-list and or-list respectively instead of phrase search.
2466 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2467 log_mask_str. This was done to avoid name conflicts with other libraries
2468 (such as other PHP extensions).
2470 Added raw OID member for preferred record syntax (request_format_raw)
2471 and returned record syntax (output_format_raw) for backend fetch method.
2473 Config file yaz-config now accepts options so that it returns specific
2474 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2476 Shared library support for UNIX using GNU libtool.
2478 * Modified backend interface. Request/Response struct's replaced by
2479 one read/write C struct. For example bend_fetchrequest and
2480 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2481 Every handler - even search has to be registered in bend_init
2482 handler. This means that the YAZ library no longer refers to
2483 external functions and it makes it possible to make the whole
2484 thing a single DLL/SO.
2486 Added Segment handler for backend server.
2488 Added Zmbol/Zebra administrative functions to YAZ client.
2490 Threaded frontend server on UNIX (when POSIX Threads are available).
2491 Starting the server with option -T enables multi-threading.
2495 Added configure option --enable-comp/disable-comp to control use
2496 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2497 located in sub directory asn.
2499 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2500 in ${exec_prefix}/bin along with the other programs yaz-client and
2503 GNU automake used to maintain makefiles.
2505 Added several OID's.
2507 Changed retrieval module so that we can load records with no abstract
2508 syntax defined. Tagpaths in these records are fully composed of string
2511 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2515 On UNIX, the generated makefile now supports a proper 'make install'.
2516 The prefix can be set via GNU configure to set the install location
2517 (default is /usr/local).
2519 * YAZ programs client and ztest were renamed to yaz-client and
2520 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2521 locations, such as /usr/bin,/usr/local/bin,etc.
2523 * YAZ Header files were moved from include to include/yaz. YAZ Header
2524 files are referred to as include <yaz/log.h> rather than <log.h>.
2525 The YAZ include path (-I ..) is therefore the same as before. Programmers
2526 should update their #include statements or use -Ipath/include/yaz
2527 instead. The main motivation for doing this change is that YAZ header files
2528 can be installed in "standard" locations /usr/include,/usr/local/include
2529 without introducing conflicts, since ALL YAZ header files are stored
2530 in subdirectory yaz (under /usr/include for example).
2532 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2533 rather than project/workspace files. We switched because project files
2534 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2537 Changed name of logging function, logf, to yaz_log, to prevent name
2538 clash with some math-log functions. The YAZ header log.h defines logf
2539 to yaz_log (#define) so there should be no incompatibilities by this
2542 Added bend_start/bend_stop handlers for server. These handler are
2543 called on start/stop of server. For windows they are called whenever
2544 a service is started/stopped.
2546 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2547 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2548 in util/yc.tcl. The auto-generated C code structures are, in a few
2549 cases, incompatible with the old decoders. There are differences in the
2550 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2551 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2552 The preprocessor variable ASN_COMPILED is defined when the compiled
2553 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2554 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2555 wish to use the old encoders/decoders you can specify --disable-yc
2558 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2559 version so that it supports both new - and old version of DB Update
2561 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2562 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2563 change. The name parameter can be set to 0 in which no name is specified
2564 for the construction. The macros odr_implicit and odr_explicit sets name
2565 parameter to zero for the construction involved. New macros
2566 odr_implicit_tag and odr_explicit_tag are similar to the others,
2567 except that a name parameter is added. For programmers' that don't use
2568 ODR they probably only need to change the call to z_APDU and z_External.
2570 Added access control facility by interfacing the TCP wrapper library.
2571 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2572 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2573 name of the daemon and enables the access control as specified in
2574 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2576 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2577 den Dool <H.M.vdnDool@kub.nl>.
2579 Added reference ID parameter to most functions in server API - refer
2580 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2582 Changed name of ccl library to libccl.a (was ccl.a).
2584 Fixed bug in decoder for Explain (Category TargetInfo).
2586 Added support for GNU readline in client. Thanks to Jacob Poulsen
2587 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2589 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2590 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2591 IMPLEMENTATION! This change was made to the development version before
2592 the ZIG decided to retract the amendment. If any users MUST be
2593 compatible with the original Update definition, PLEASE CONTACT US, and
2594 we will include a separate definition corresponding to the old Update
2595 ES. Note that because of the change to the ASN.1 of the
2596 TaskPackageRecordStructure we cannot define a single structure that
2597 will support both versions.
2599 * Added const modifier to buffer parameter for some ODR/BER encoding
2600 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2601 completeWAIS, odr_dumpBER.
2603 Fixed bug in client.c which caused a crash when a scanResponse didn't
2604 contain positionOfTerm.
2606 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2607 * will cause an error in a client if a non-YAZ target sends both a
2608 * list of Scan entries and non-surrogate diagnostics.
2610 Retrieval module enhancements. Tag sets may be typed in the reference
2611 to it. From the .abs-file the "tagset" directive takes a third optional
2612 integer type for the tag set referenced. From a .tag-file the "include"
2613 directive takes a third optional type as well. The old "type" directive
2614 in the tag set itself is still recognized but acts as the default type
2617 Backend interface change. Individual Scan terms returned from bend_scan
2618 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2619 in include/backend.h.
2621 Retrieval module enhancements. Multiple tag sets and attribute sets may
2622 be specified in abstract syntax specs. Revised the error/warning for
2623 logging messages reported by the retrieval module when reading the
2626 Object Identifier system (oid_..) changed. The API is backwards
2627 compatible but the oid-routines now allocates new OID's when needed.
2628 Raw OID's may be specified in oid_getvalbyname.
2630 YAZ now uses GNU configure to generate Makefile(s).
2632 * Minor changes in some of the member names of DeleteResultSetRequest and
2633 DeleteResultSetResponse. See include/proto.h.
2635 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2636 and added member 'languages' in TargetInfo (which was missing).
2638 Changed the way attribute sets are handled in the retrieval
2639 module. These are now cached, just like the abstract syntaxes
2642 Changed YAZ so that it links with compiled ASN.1.
2644 Added Explain-schema definitions and mapping routines. The following
2645 Explain categories have been implemented: AttributeDetails,
2646 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2648 Fixed minor bug in Windows version of Server Library.
2650 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2652 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2654 Added EXTERNAL: UNIverse Resource Report (non-standard).
2656 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2657 ENUMERATED and SET OF.
2659 * Added 'const' to some of the char pointer arguments for the
2660 functions, data1_read_node, data1_getelementbytagname,
2661 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2664 Fixed bug in data1_insert_taggeddata - the last_child member of
2665 parent wasn't initialised.
2667 * Changed data1_read_record and data1_read_node so that the supplied
2668 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2669 doesn't refer to any parts of the "SGML"-buffer.
2671 Fixed bug in server library (Windows version of statserv_remove).
2673 * Changed code so that it compiles as C++. The type definition
2674 of Odr_fun which is a member of Odr_arm was changed. The result is,
2675 that an explicit typecast is needed for the fun pointer when
2676 using Odr_arm - as in:
2677 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2679 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2681 Implemented the new structured date and time definition as approved
2682 by the ZIG. Added schemaId element to the specificTag in Espec-1
2683 (also approved at the last ZIG). Thanks to RVDM.
2685 Added some Object identifiers (RVDM).
2687 Changed the Update Extended Service (RVDM).
2689 Added command "refid" to client which specifies referenceId for
2690 the following requests.
2692 Implemented extended service handling for server. See ztest.c
2693 for an example as well as backend.h. New handlers are registerd
2694 in the Init handler.
2696 * Changed interface for sort in server.
2698 Added new members to statserv_options_block. It allows a server
2699 to read options from another source than just the command line. Thanks
2700 to Charles Woodfield.
2702 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2703 renamed to zboolean. Some C++ compilers complained about the name.
2705 Minor changes to gils.abs. Added index 's' (sort) on title
2706 and date/time-last-modified.
2708 --- 1.4pl2 1998/1/30
2710 Fixed bug in server library regarding inetd mode (-i). This bug
2711 was introduced by release 1.4.
2713 --- 1.4pl1 1998/1/29
2715 Added sort facility in client and backend server interface.
2717 Fixed problem with dependencies in Makefile(s).
2719 Fixed bugs for encoders/decoders of extended services and
2722 Implemented sub-tree feature for schemas. Sub-trees are
2723 referenced in *.abs-files. See explain.abs for an example
2724 of the use of this feature.
2726 Modified bib1.att; local attributes for ANY didn't include
2727 ANY itself (only affects use of the retrieval module).
2729 Fixed bug in plain SGML reader in function data1_read_node:
2730 tags with prefix "var" was incorrectly interpreted as variants.
2732 Added feature "sub-schemas" to enable references to - and definitions
2733 of - group of elements.
2735 * Removed member parent from type data1_element (in data1.h).
2737 Implemented function odr_nullval() that returns the value of
2740 * Removed member num_children from data1_node (in data1.h).
2742 Made NT service interface part of the server library. The
2743 function statserv_main uses the NT service when required and
2744 calls the statserv_start / statserv_close routines.
2746 Routine zget_SearchRequest and zget_PresentRequest fills
2747 resultSetName/Id member with "default" instead of "Default".
2749 Fixed memory leak in server. Request queue member wasn't freed.
2751 Fixed nmem_exit so that memory is freed.
2755 Revised the CCL parser utility to be thread safe.
2757 Added function, oid_ent_to_oid, to replace the function
2758 oid_getoidbyent, which is not thread safe.
2760 * Added nmem_init and nmem_exit to initialize and release
2761 NMEM resources. Function nmem_init should be called once in the
2762 initial thread before NMEM/ODR is used. statserv.c and client.c
2763 have been changed accordingly. The change was necessary to make
2764 NMEM thread safe. The NMEM memory pool is shared amongst threads
2765 in a process. Unix-based applications will still work fine without
2768 Added NT Services interface for the the Z39.50 (statserv) Server.
2769 Refer to the ztest.c source on the usage.
2771 Windows 95/NT port using MSVC5.0. Project files are included in the
2774 * Defined new 'global' handle for the retrieval (data1) system. The
2775 new handled, data1_handle, describes the state of the data1 system.
2776 This handle is passed as first argument to virtually all
2777 data1 related routines. The functions data1_create and data1_destroy
2778 creates and destroys a data1 handle respectively.
2780 Added ODR encode stream member to all backend request structures
2781 init, search, scan etc. This stream should be used to allocate all
2782 memory used for the response when thread safe operation is needed.
2784 Changed the comstack utility, cs_addstr, to be thread safe. The
2785 returned hostname string returned by the function is now part the
2788 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2789 function. The cs_straddr takes a COMSTACK handle as argument, so this
2790 function must be used after cs_create and before bind/connect.
2791 This function is thread safe.
2793 Moved test server to 'ztest' directory - generic server code still
2794 in 'server' directory.
2796 Made prefix query (pquery.c) utility thread safe.
2798 Added new function modifier YAZ_EXPORT to 'export' public DLL
2799 functions when using windows (see include/yconfig.h).
2801 Added definitions to the OID database (util/oid.c) (RVDM).
2803 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2805 Added call to ccl_rpn_delete in client program.
2807 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2808 release of RPN structure.
2810 Added support for C++, headers uses extern "C" for public definitions.
2811 With input from RVDM.
2813 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2814 Thanks to Ronald van der Meer (RVDM).
2816 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2818 Added support for private extensions to the OID database
2819 (oid_setprivateoids()). Thanks to RVDM.
2821 Added optional, physical ANY (key replication)
2823 Fixed null-reference problem in GRS-1 output filter.
2825 Proximity operator added to Prefix Query Format (PQF).
2827 In test client command "base" accepts multiple databases.
2829 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2833 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2835 Smallish bug-fixes in the new encoders/decoders (explain).
2837 Bug fixed in DeleteRequest.
2839 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2841 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2843 Added SOIF syntax (using private OID for now) to retrieval module and client.
2845 Added Update extended service.
2847 Added SearchResult-1 additional info structure.
2849 Added optional CCL (ISO8777) interpreter as separate module. Available
2852 --- 1.2 1996/6/10 (1st anniversary release)
2854 Added Summary record syntax. Lightly tested.
2856 Added OPAC record syntax. Untested.
2858 Added ResourceReport service encoders/decoders. Untested.
2860 Fixed bug in z_Unit - wrong tagging on unitSystem.
2862 Fixed bug in the DiagRecs decoder.
2864 Added options for max PDU size and session timeout to frontend-server.
2866 Added documentation of query-language parsers and other supporting utilities.
2868 [frontend-server] Added Attribute set to the bend_scanrequest API.
2870 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2871 surrogate diagnostics were generated.
2873 [retrieval] Allow multiple local values for attribute.
2875 [retrieval] Allow multiple attributes per element in .abs files. index type.
2877 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2879 --- 1.1pl2 1996/4/10
2881 Minor changes, mostly specific to Zebra's requirements (retrieval)
2885 Repaired bug in frontend server when running multiple listening
2886 endpoints in dynamic mode.
2888 z_External() now won't break if a known, ASN.1 value comes encapsulated
2889 in an octet-string. The value will pass through unmodified in an Odr_oct.
2891 Added a bit of code to the demo client to decode & display
2892 ASN.1-structured records represented in the octet-aligned branch of
2893 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2895 Added z_ext_getentbyref() to the ASN module. Doc updated.
2897 * Completed the SCAN definition in the ASN module. This may break SCAN
2898 code based on older YAZ-versions at compile-time. The fix is easy -
2901 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2902 under the SCAN definition. Remember to initialize this, server-people.
2904 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2905 that this does not extend to ODR and ASN.
2907 Comstack allows insertion of established socket (primarily for
2908 inetd-operation of servers). Doc updated.
2910 Front-end server can now start from the inetd in TCP mode. Doc
2913 --- 1.0pl4 1996/1/24
2917 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2918 the rank and record number.
2920 Adjustments to the frontend server.
2922 Fixed diagnostic BER dumper. It ignored the file argument.
2926 Various changes to retrieval module.
2928 Changed the union discriminators of the protocol files from enums to
2929 ints paired with #defines.
2931 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2934 *Changed operator in the RPN structure to 'roperator', again to avoid a
2937 Fixed problems in Explain decoders/encoders.
2939 --- 1.0pl2 1995/12/6
2941 Memory bug in log module fixed.
2943 --- 1.0pl1 1995/12/5
2945 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2947 Bug in Explain DatabaseInfo module fixed.
2949 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2953 The shift to v1.0 signals that we now consider the *core* functionality
2954 of YAZ reasonably stable (the core being more or less equivalent to
2955 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2956 tested (Explain not at all - though that will happen soonish).
2958 Minor changes to code to support Windows port.
2960 Various minor changes after we're getting to use GRS-1 & co. more.
2962 Added Espec-1 format.
2964 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2965 of the protocol and it cannot be selected when encoding (maps into 'string'
2966 when decoding). Needed to talk to some servers.
2968 Demo client can request simple element set names.
2970 Added Diagnostic Format encoders/decoders.
2972 Added simple Close handling to frontend server (no hooks for resource
2973 reporting yet), and demonstration client.
2975 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2977 --- 1.0b3 1995/08/24
2979 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2980 handled incorrectly when records were requested in the searchResponse. This
2981 will only affect you if you use the frontend-server.
2983 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2984 Test-client will ask for and print GRS1. Ztest will return dummy records
2987 Added Explain encoders/decoders to the service-level API. Untested.
2989 Added Extended Services: Item Order encoders and decoders to the Service-
2990 level API. Untested. We could use a recent copy of the pertinent bits
2991 of the ILL protocol to add those bits.
2993 Added diagnostic format 1 encoders/decoders to the service-level API.
2996 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2997 odr_cons.c, which causes a more correct output.
2999 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3000 was always set to 0 when no records were requested in the searchRequest.
3002 * Added better external-handling. This shouldn't harm old code that
3003 *encodes* externals. It can break code that looks for a
3004 'single-ASN1-type' representation, since those types that are known
3005 are now decoded immediately. Look at the SUTRS sample code in
3006 seshigh.c and client.c. Documentation updated.
3008 Handling of structured records in bend_fetchresponse. Length -1 marks
3009 structured record, type is deduced from format field.
3011 --- 1.0b2 1995/06/27
3012 Fairly quick maintenance release to add SUTRS support.
3014 Fixed handling of SUTRS records in the demonstration client.
3016 * Added format field to the bend_fetchrequest and bend_fetchresponce
3017 structures of the backend API (frontend server). When the record is
3018 returned, the value of the format field is mapped to an OID. The
3019 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3020 of the record. The special value VAL_NONE in the bend_request means
3021 that no specific format was requested by the client. Documentation
3022 updated accordingly. Test server (ztest) will return a fixed dummy
3023 SUTRS record if your client requests SUTRS.
3025 Documentation updated accordingly.
3027 You can now set external libraries and RANLIB support in the top-level
3031 First public release.
