3 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
4 back-end's addinfo through into the ZOOM response addinfo.
6 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
7 they are separated by a colon and a space rather than simply
12 Add support for Solr spell-checking/suggestions through ZOOM.
13 If a Solr target has been configured correctly for spelling-checking
14 and suggestions, these will now be returned on the ResultSet option
15 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
19 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
20 with a flag whether to substitute escape sequences or not.
24 Fix nmem_strsplit_escape to substitute escape char properly.
26 New option for zoomsh -e , which makes it abort on first error and
27 return process exit code to indicate success/failure.
29 YAZ options utility supports special option -- which makes all it treat
30 all following arguments as non-options.
34 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
35 searched if absolute filename is given.
37 Fix conv_xslt() error-reporting when stylesheet is not found.
38 (The value of fullpath is meaningless in this situation.)
42 Fix problem in CQL sort node creation: un-initialized memory.
44 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
45 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
46 CQL sortby depending on whether Type-1 or CQL is actually sent to the
49 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
50 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
52 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
53 will make it possible to use both single-character mask (#) and wildcard (?)
54 in CCL . Throw diagnostic for left truncation because that is not supported
59 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
60 cases using escapes (\-sequences) and masking.
62 PQF parse fix: A trailing backslash followed by end-of-string (\0)
63 would result in a read one byte beyond string.
65 rpn2ccl may use Z39.50 masking for terms (t=z).
67 ICU check fix. Don't include library -lCrun on Solaris, unless present.
69 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
70 not --cppflags (which seeems like an error in icu-config).
72 -- 4.2.12 2011/08/27 RPM package only
74 cql2ccl: fix conversion of terms: operator characters were not
77 -- 4.2.11 2011/08/25 RPM package only
79 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
80 CCL parser will map both # and ? to their regular expression
81 quivalents (. and .*).
83 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
84 of reserved CQL characters.
86 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
87 is, so that they are passed through.
91 ZOOM SRU mode: more aggressive re-connect.
93 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
94 made available as a utility function, declared in <yaz/logrpn.h>
96 rpn2cql_structure() supports proximity nodes (except that the Type-1
97 proximity node's "exclusion" binary is ignored, as there is no way to
98 express that in CQL). Fixes bug #4564.
102 Fix SEGV that could occur if set command of zoomsh was given without
103 value (2nd argument).
105 Fix SEGV that could occur if unsupported transport was given for
106 COMSTACK - say https (when SSL was unavailable).
108 Build yaz-url on Windows too.
112 New utility to get web content. Header is url.h. A command line tool
113 yaz-url is part of the distribution and packages.
115 Fixes for SSL COMSTACK (when gnutls is in use).
117 New functions yaz_base64{encode,decode}. Header is base64.h.
121 ZOOM C includes HTTP response buffer as additional info if it fails
122 to decode the SRU response.
124 Make wrbuf_json_puts available.
128 zoom: throw diagnostic for invalid value for option "sru". Before a
129 bad SRU request was sent.
131 Adding new utility wrbuf_vp_puts.
133 Add cclxmlconfig.obj to win/makefile. It was missing completely.
137 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
138 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
139 redirect was used at the same time.
141 MARC line mode decoding: be less picky about length given - first
142 5 digits of header that is.
144 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
146 Changes to decoding of SRU records: a record with recordPacking=xml is
147 modified with a new root element <yaz_record> if the recordData contains
148 multiple children elements. This is to make the record XML parseable
151 RPN to SOLR conversion: encode special characters.
153 Generic Frontend Server: fix uinitialized member, stepSize.
157 Fix a bug in SRU decoding of records.. The database records stored
158 had un-initialized memory, but it would only be seen with yaz_record_render
159 and type_spec="ext" .
161 Fix a bug in ccl_qual_dup introduced in 4.2.3.
165 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
169 Add new utilities to convert from CQL to CCL . These utilities have
170 prefix cql_to_ccl defined in cql.h.
172 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
173 lead to memory heap corruptions when ICU utilities were in use.
177 Make compilation work without Libxml2.
179 yaz-client: remove redundant blanks in display of searchResult-1 term
184 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
185 resulting CQL node (tree) in a new node CQL_NODE_SORT.
187 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
188 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
189 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
190 Note that the CQL sortby spec is only converted when the GFS is already
191 converting from CQL to RPN (cql2rpn element).
193 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
194 specify whether to collapse delimitors or not. The existing nmem_strsplit
195 do collapse (collapse parameter = 1).
197 Windows installer: For NSIS, set InstallDir depending on x86/x64.
199 Rename internal func yaz_use_attribute_create. While non-static, this
200 function is not declared in a public header.
204 Add -lCrun when linking with ICU on Solaris.
206 More quicks character set conversions for OPAC records.
210 fix problem with record_render: records were converted (character set
211 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
215 SRU: add methods for handling DADS SRU-proxy facets.
217 Separate OPAC record character set for ZOOM_record. yaz_record_render
218 allows a character set given as charset=from/opacfrom,to where 'from' is
219 the character set of a bibliographic record, 'opacfrom' is character set
220 of OPAC record and 'to' is the target character set.
224 yaz-client: show may XML format records. Command show followed by 'format'
225 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
228 src/stemmer.c: Avoid using unnamed union. It is not supported by some
231 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
234 Update yaz.spec to operate on both SLES11 / Centos 5.5.
236 RPM: Release includes 'indexdata' name. Use indexdata in release name so
237 this package can be distinguished from other vendors.
239 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
240 as determined by configure
242 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
244 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
245 returns no error and no record, the present request is considered
246 partial (only a subset of the records could be returned by backend), and
247 so it is appropriate to set Present Status to partial-4.
251 Move yaz-config man pages to section 1.
253 More documentation about SOLR.
255 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
256 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
257 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
258 peers on some Linux systems. However, in general that does not work
259 so YAZ can not rely on that to work. Debian changed behavior in this
260 respect from Debian lenny to Debian squeeze (still testing as of Oct
262 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
264 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
268 Fix yaz-config output: echo_source not set correctly by configure.
272 SOLR WebService support for yaz-client and ZOOM.
274 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
276 --- 4.0.12 2010/08/17
278 Z39.50 facet support. Facet specifications are passed for search in
279 other-information with ASN.1 as defined in facet.asn and OID
280 .10.1000.81.5 . Facets are expressed as an Attribute list as known
281 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
282 3 is limit (number of entries to get in response). yaz-ztest returns
283 dummy facets if a client asks for them.
285 --- 4.0.11 2010/07/09
287 CCL fixes: bug 2895 and bug 3539.
289 GR1-display: add comma in display - was removed by mistake in
292 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
294 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
296 --- 4.0.10 2010/06/18
298 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
299 result set from a connection. The result set will be on its own
300 thereafter; no operations on it will perform retrievals from a target.
301 Only cached copies are returned.
303 ZOOM C:fix case for HTTP servers responding with Connection:close.
304 Ensure that if there is a current task it is resumed (like fetching
305 more records in a result set) . Bug #3484.
307 PQF parser: use odr_atoi for Odr_int (not atoi)
309 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
310 values that contain any non-digits are treated as string attributes
311 (previously decoding only checked for leading character ([0-9]). PQF
312 encoding: attribute string values are not surrounded by double-quotes.
316 New utility for managing threads - thread_create.h.
318 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
319 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
320 but YAZ' implementation do.
322 Fixes for yaz_cond-functions on Windows 7.
324 DLL export more symbols.
326 zoomsh: show record do NOT render opac.
328 Remove *.la files from Debian and RPM packages.
332 Debian package libyaz-dev depends on libgnutls-dev again (was
333 removed in YAZ 4.0.6, but due to Libtool it is still needed
334 even though yaz-config do not list libgnutls libs).
336 ZOOM: Use only one WRBUF for returning string results for
337 ZOOM_resultset. Reduces memory usage for ZOOM in general.
339 ZOOM: ZOOM_connection do not use a shared pointer to
340 ZOOM_resultset after ZOOM_resultset is destructed by
341 user. Reverts to YAZ 4.0.4 behavior.
345 record-conv: fix problem with at least one XSL conversion -
346 due to probably incorrect usage of XML XSL documents.
350 Fix yaz-config for static mode and the use of SSL (gnutls).
354 Forward decl timeval struct in mutex.h and gettimeofday.h.
356 yaz-config: fix 'static' mode linking.
360 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
361 are wrappers for pthreads or Windows. For Windows these are put in
362 a separate DLL: yaz_cond4.
364 libyaz.la (whole source) is compiled with thread. If thread support
365 is enabled enabled, all source of YAZ is compiled with treading support.
366 This allows core utilities such as yaz_log to use thread facilities.
367 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
368 thread utilities. This commit moves mutex utilities (mutex.c) from
369 libyaz_server.la to libyaz.la.
371 yaz-json-parse displays leading text until error.
375 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
376 patch from Giannis Kosmas.
378 SRU: no longer URL encode SRU database. The URL for an SRU server is
379 a URL and such is alreeady encoded - at least when given with leading
380 http:// or https://. This reverts behavior to YAZ 3.0.50.
382 Support for new MARC XML notation TurboMARC which like MARCXML is a
383 complete representation of MARC/ISO2709.. This one, however, is more
384 compact and allows for faster processing with XSLT. TurboMARC can be
385 used in the marcdisp.h API, from the yaz-marcdump utility and from
388 yaz-ztest can be configured - via the database - to perform certain
389 delays when it performs operations search, present and single record
390 fetch. This allows testers to make yaz-ztest act as a real or even slow
391 Z39.50 server. Refer to the yaz-ztest man pages for details.
395 wrbuf_destroy allows NULL WRBUF passed to it.
397 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
399 Add ZOOM_connection_close.
401 No fixed size buffers for ZOOM shell - bug #3257.
403 tstodr: make it work on s390 platform.
405 New icu iterator-functions. The new icu_iter-functions makes it possible
406 to use ICU chains from many threads.
408 yaz-client: better syntax check for show command.
412 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
415 New simple local-file XML include facility which allows file glob-patterns.
416 Refer to yaz/xml_include.h.
418 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
421 ZOOM_record_get supports new parameter "format" which makes it format XML
424 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
425 JSONText in ECMA-262) is JSONValue, not JSONObject.
429 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
430 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
432 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
433 POSIX/Unix builds .so with major version 4.
435 Remove old LOG_-defines from log.h. They have been obsolete and
436 undefined by default for the last 5 years.
438 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
440 GFS: Remove socket (int *fd) from search_rr handler. The socket
441 descriptor ptr is a facility that allowed a search handler to supply
442 a socket which would serve as a callback - when search was complete.
443 This facility has now been in use for years.
445 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
446 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
447 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
448 returns 'const char *' rather than 'char *. The returned string is
449 read-only and should not be modified by applications. COMSTACK cs_close is
450 now a void function - it no longer returns int. No applications check for
451 the value and the implementations has always returned 0.
453 ZOOM: use size_t for scan hit counts and str size. Functions
454 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
455 occ (hit count) and len (string length) are now of type size_t pointer
456 rather than int pointer. This is to be able to represent large hit counts
457 and to also just to use the proper type for string length (strlen result).
459 New JSON parser. Refer to include/yaz/json.h .
461 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
462 Used to be int in some cases. Many wrbuf_-functions used to return an int
463 indicating some length.. These return values were never used. And so they
466 ODR: odr_malloc, odr_total now takes size_t for size.
468 clone_z_type: fix leak; occurred for encoding failures.
470 --- 3.0.52 2009/12/03
472 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
473 bug was introduced in 3.0.51.
475 --- 3.0.51 2009/12/02
477 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
479 tcpip comstack: fix leak for getaddrinfo.
481 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
482 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
483 Decoding of SRU "path" database is performed by private function
484 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
485 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
487 yaz-client: honor base command for SRU. Change when database setting
488 is applied for SRU and ensure it is kept when a connection is reset.
489 Change also the way errors are displayed or SRU (decoding of packages).
491 --- 3.0.50 2009/11/02
493 Add support for extra request / response data for SRU codecs and GFS.
494 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
495 for extra data response buffer and length. For the GFS, both request
496 and response data (XML) is carried in extra_args and extra_response_data
497 for the search handler. Patch by Ko van der Sloot.
499 ZOOM: For queries that cannot be converted to the specified rpnCharset,
500 ZOOM now returns a diagnostic on the client-side ('invalid query' /
501 10010). This fixes bug #2113.
503 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
504 cmdfile included a 'quit' command that would result in a memory violation.
506 --- 3.0.49 2009/10/01
508 Make a number of functions defined in xmlquery.c static. These have
509 never been declared in a public header file (yaz/xmlquery.h) and was
510 made public by mistake.
512 Improve speed of character conversions (iconv utilities). This makes
513 conversions from MARC-8 faster.
515 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
516 unless type desired is "raw". This will prevent type "xml" from
517 returning ISO2709 .. Which obviously can not be XML parsed.
519 Fix memory leak in ZOOM that would occur if option apdulog was used
520 on a re-used connection.
522 Frontend server logs HTTP requests.
524 Frontend server now sends Z39.50 close when it times out (sesssion has
525 been idle for too long). Versions 2.0.30 and earlier also sent close.
526 But due to a mistake this was disabled in all versions after that, i.e.
527 the server would just close the socket immediately.
529 yaz-client emits a better message when receiving an unrecognised
530 userInformationField.
532 Skip zero-length subfields when decoding ISO2709. This rare case happens
533 if a record has two FS characters in a sequence. Without this patch
534 there would be a reference beyond char array in using_code_len fragments
537 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
539 --- 3.0.48 2009/08/28
541 The show command offered by the zoomsh command now takes a 3d optional
542 parameter type which is what is passed to ZOOM_record. If the type
543 argument is omitted, "render" is used.
545 RPN to CQL conv may use USE string attributes (bug #2978).
547 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
549 --- 3.0.47 2009/07/08
551 Function yaz_xml2query allows a diagnostic element in the PQF XML
552 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
553 code and additional info respectively.
555 The BER BOOLEAN is now the integral type Odr_bool which still happens
556 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
557 typedef'd to Odr_int. This is still an integral 'int', but it may be
558 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
559 ASN-1 compiler as well as programs has been updated to use the new types.
561 --- 3.0.46 2009/06/08
563 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
564 only the bibliographic record was rendered. For type=opac, an OPAC
565 record is only returned if it is present.
567 iconv: small fix for encoding of advancegreek.
569 yaz-client: avoid double display of SRU/SRW records (bug #2798).
571 yaz-client: option auto_reconnect=on really reconnects.
573 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
575 server: avoid null ptr ref for for yaz_poll errors.
577 build: fix RPM build for RHEL 5.3.
579 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
581 --- 3.0.45 2009/03/31
583 Fixed bug #2709: TCP connect returns Invalid argument.
585 Fixed compilation for mingw.
587 Honor charset for raw records (ZOOM_record_get).
589 Fixed use of errno for threaded mode that was seen on Solaris 10.
591 Fixed argument passing with blanks in value for Windows Service.
593 Disable YAZ' own log rotate by default (no 1 GB limit).
594 The variable l_max_size which specifies the log file limit is set to 0
595 (DISABLED): This is due to the fact that YAZ is most often deployed using
596 logrotate. Also YAZ can not perform log rotate because of unsufficient
597 permissions (setuid).
599 --- 3.0.44 2009/02/17
601 List supported encodings in man page for yaz-iconv.
603 Fixed missing SSL libs for --libs output
605 Re-established OID record syntax application-xml. Nobody should use it
606 but we don't want to change soname because of this symbol being absent.
608 --- 3.0.42 2009/02/02
610 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
612 Added member named_result_sets for init handler struct for the GFS. This
613 allows a server to disable named result sets.
615 Removed OID record syntax application-xml.
617 Added support for rule-based transliterator for ICU wrapper of YAZ.
619 Fixed bug #1902: yaz-icu XML output.
621 Make YAZ checks Emacs friendly.
623 BITSTRING value shows value. Bug #2346.
625 ISO2709 decoding: skip control characters from indicator data.
627 Omit sort key by default in yaz-icu's output.
629 Allow combined single char options (again) for YAZ' options function.
631 Utility yaz-marcdump got option to display YAZ version (-V).
633 Allow YAZ to use ICU 3.4.
635 Added new ICU test case which illustrates removal of diacritics.
637 --- 3.0.41 2008/12/29
639 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
641 --- 3.0.40 2008/12/29
643 For configure, using option --without-xml2 also disables Libxslt/Libexslt
646 Fixed bug #2352: yaz-marcdump crashes for certain record.
648 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
650 Added support for Danmarc2 to UTF-8 conversion.
652 Added support for ISO5426 to UTF-8 conversion.
654 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
655 implementation version.
657 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
659 --- 3.0.38 2008/11/10
661 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
662 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
664 ZOOM C now interprets databaseName option for ZOOM connection as path
667 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
669 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
671 Dummy Libxml2 types no longer defined in headers of YAZ'.
673 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
676 --- 3.0.36 2008/09/26
678 Various ODR chapter fixes.
680 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
682 Added missing source for Windows compilation, mutex.c.
684 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
686 For SRU connections in ZOOM all records up to "count" are now fetched.
688 Fixed crash in generic frontend server (and yaz-ztest) which occurred
689 in Windows due to bad error handling for Libxml2.
691 Added facility for sending arbitrary records (ASN.1 any) using
692 ZOOM C's Extended service update. Patch by Sam Reynolds.
694 New options for ZOOM C's connection, logapdu which makes ZOOM log
697 --- 3.0.34 2008/06/18
699 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
701 --- 3.0.32 2008/06/12
703 Fixed memory violation that could occur when decoding UTF-8. This bug
704 was only present in 3.0.30 of YAZ.
706 --- 3.0.30 2008/06/06
708 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
709 GNU TLS is used by default (if found).
711 yaz-ztest returns OPAC records if a client asks for OPAC.
713 Improved speed of MARC-8 encoding.
715 Added support for lossy and loss-less MARC-8 encoding.
717 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
719 Added new Windows Service wrapper (sc).
721 yaz-client's itemorder command may now send a file.
723 Fixed yaz-marcdump to allow the use of NS prefix for record element.
725 Added new function yaz_log_xml_errors.
727 Allow (but warn) unknown XML attributes in MARCXML parsing.
729 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
731 The UTF-8 to MARC-8 conversion now uses a different set of characters
732 for Greek symbols. Bug #2120.
734 --- 3.0.26 2008/02/21
736 Added yaz_daemon (daemon.h).
738 Fixed bug #2068: pkg-config trouble
740 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
742 --- 3.0.24 2008/01/28
744 Document --with-xml2 option.
746 Added OPAC XML XSD (etc/opacxml.xsd).
748 Allow glob mask for name attribute in retrieval element for the
749 generic frontend server's retrieval facility.
751 Changed yaz_poll_poll to return yaz_poll_except for all returned events
752 except POLLIN/POLLOUT.
754 Fixed error handling in cs_listen. Bug #2037.
756 --- 3.0.22 2008/01/20
758 Fixed version in yaz/yaz-version.h.
760 Fixed bug #2027: Crash when closing connection.
762 Changed configure so that ICU support is only enabled if only ICU
763 and Libxml2 is available (because the ICU chain is XML based).
765 --- 3.0.20 2008/01/15
767 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
768 is built. Only this DLL depends on the ICU runtime.
770 yaz-ziffy is no longer part of YAZ. It is distributed separately by
771 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
773 Changed license of CCL module to 'Revised BSD'. After consultation with
774 remaining members of the original EUROPAGATE consortium, we are re-issuing
775 the CCL module without a separate license. The software was developed by
776 Index Data as part of a research project. The special license was included
777 to help feed usage information back to the project consortium to support
778 project evaluation. At this time, the project consortium has long-since
779 disbanded, and the majority of the original principals have retired. At the
780 same time, we have significantly modified the software during the following
781 years, to the point where very practically no original code remains. To
782 simplify re-use of the software, we have contacted those members of the
783 consortium who could be reached, and agreed to re-issue the module as a
784 proper part of the YAZ package.
786 Tcl scripts uses /usr/bin/tclsh as preferred shell.
788 CQL closer to being version 1.2 compliant. CQL also allows free-form
789 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
792 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
793 bug could make Extended services handling crash in the ZOOM layer. This
794 bug was only present in YAZ 3.0.18.
796 --- 3.0.18 2007/12/19
798 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
801 yaz-marcdump reads and writes collection wrapped records.
803 Handle OPAC for record conversion module.
805 Fixes for ICU wrapper.
807 Allow ICU libs to be controlled with --with-icu .
809 --- 3.0.16 2007/11/12
811 Added yaz_poll which is a wrapper for select/poll. When poll is available
812 and non-buggy, it is used, by yaz_poll . This allows more than 1024
813 sockets to be in use.
815 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
816 functionality through an XML based configuration (ICU chain). This system
817 is useful for search facilities such as Pazpar2 and Zebra that needs to
818 perform tokenization of indexed material. The ICU code in a separate
819 library libyaz3_icu.a.
821 Added HTTP tunnel facility for COMSTACK, bug #1752.
822 This is a facility that allows a Web proxy, such as squid, to tunnel
823 Z39.50 traffic. This facility is "transparent" to must applications
824 using YAZ. It's enabled by using pseudo transport connect: followed by
825 the proxy address, followed by command, then follwed by he regular
826 "virtual" addresss. For example,
827 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
829 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
831 --- 3.0.14 2007/09/21
833 Fixed bad memory reference in ZOOM_record - cuased by member not being
834 initialized. This was a problem only in YAZ 3.0.12.
836 Fixed bug in conversion from MARC to XML: Non-XML characters in control
837 fields were not removed.
839 Changed the way C code is generated from codetables.xml. Made a MARC-8
840 conversion trie for each characterSet section rather than codeTable.
841 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
842 of codetables.xml from Larry Dixson, LOC. Bug #1464.
844 --- 3.0.12 2007/09/12
846 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
847 from ZOOM_record_error).
849 ZOOM C function ZOOM_record_get returns record schema for type="schema".
851 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
853 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
855 Better SRW-to-Bib-1 diagnostic mapping.
857 ZOOM C and yaz-client announces SRU version 1.2 by default.
859 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
862 Fixed in yaz_sru_decode to allow other version than 1.1.
864 --- 3.0.10 2007/08/22
866 Added support for SRU scan for ZOOM.
868 Added support for the use of the older versions or Extended Service
869 Update in ZOOM. To faciliate this, an option "updateVersion" may be
870 set to the version , 1=first, 2=second, 3=third. The third version is
871 what ZOOM C has used so far. And that, obviously, is the default.
873 Added support for CCL queries in Z39.50 queries sent to the GFS (and
874 therefore in Zebra and in SimpleServer-based applications). The new
875 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
876 qualifier file used to transform incoming CCL queries into Type-1 RPN,
877 which is passed into the back-end search callback function.
879 Added support for HTTP Basic authentication in clients: the SRU/W
880 codec encodes the username/password elements of the PDU structure
881 appropriately, and these may be set using the "user" and "password"
882 options in ZOOM-C applications (the same options that are used for
883 Z39.50 authentication).
887 Fixed bug #1208: SSL appears to be broken in ZOOM.
889 Fixed bug #1206: Libxml2 include path weirdness.
891 Added oid_name_to_dotstring.
893 Allow elementSetName to be specified for ZOOM C record update.
895 Allow waitAction to be specified for ZOOM C based for Extended Services.
897 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
898 syntax OID. Bug introduced in YAZ 3 series.
900 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
904 Fixed bug #1157: yaz-client does not read .yazclientrc from current
905 directory. yaz-client now reads commands from file given by option -f
906 if specified; then tries to read .yazclientrc in current directory.
907 Failing that, it reads .yazclientrc from user's home directory.
909 Added support for correlationInfo Note and ID for Record Update via
912 Added yaz-client command querycharset which specifies character set for
913 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
914 (termListAndStartPoint).
916 Charset ISO5428:1984 is an alias for ISO5428-1984.
918 Implemented a way to perform scan in a result set using Z39.50. This
919 is achieved by attaching the result set name in the characterInfo
920 (type InternationalString) of OtherInformation in the Scan Request PDU.
921 The result set is identified in the otherinformation by the new OID:
922 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
923 This allows for scan in result set and faceted search . Zebra did some
924 of this in the APT term using attribute type 8 and value being result
925 set. Using the OtherInformation approach for this is cleaner and easier
926 to work with in proxies and the like. This facility can be used in
927 yaz-client using new command setscan which takes a result set as first
928 argument, start position (APT) as second.
930 Changed decoding of SRU XML packed records to deal with servers that
931 have recordData with XML data with multiple root nodes. Also make
932 comparison for recordPacking case insensitive. Again, one server
933 returns "XML" where others return "xml".
935 For SRU responses allow Content-Type application/xml as well as text/xml.
939 Fixed bug in character set conversion of BER strings. Bug introduced
944 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
946 For OID class, use oid_class consistently.
948 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
951 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
952 character set for bibliographic information interchange". By Giannis Kosmas.
954 Added documentation on new OID API.
958 Changes to generic frontend server interface: added new member
959 'query_charset' for bend_initrequest structure. A backend init handler
960 should set this member to its native character set for query terms.
961 When defined, the frontend server logic will announce this character set
962 to a client if the negotiationModel bit is set by the client. All server
963 implementors are encouraged to specify this. If a backend server does not
964 specify this a warning is issued using yaz_log(YLOG_WARN,..).
966 Added CCL utility to remove terms (stop words) from resulting RPN
967 tree. This is handled by functions with prefix ccl_stop_words_ .
969 New ZOOM C option, "rpnCharset", which allows client-side conversion of
970 terms in RPN queries.
972 Clean-up the CCL API. Moved some internal structures from ccl.h to
973 private header cclp.h. Changed ccl_parser_create so that a Bibset must
974 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
975 This is replaced by ccl_parser_find_str which takes a string instead.
977 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
978 libyaz.la is the core of YAZ except the generic frontend server and
979 does not depend on POSIX threads anymore. libyaz_server.la is the
980 generic frontend server facilities and uses POSIX thread functionality
981 if available. The libyaz.la no longer depends on POSIX threads because
982 the number of global structures is limited. NMEM no longer re-uses blocks
983 between threads ; it simply free's memory immediately but allocates in
984 "large" chunks as usual. We don't expect any performance penalties
985 because of this. The yaz_log system is still using a global log_level so
986 caution must be taken when modifying it with yaz_log_init_.. +
987 yaz_log_mask_str. This, however, should not cause any trouble because
988 these functions are called during initialization of application code
989 anyway. `yaz-config --libs server` returns libs for server applications;
990 `yaz-config --libs` returns libs for non-server applications.
992 New OID database - with public definitions in oid_db.h. Removed old OID
993 database including the head oid.h and definitions such as enum oid_value
994 and struct oident. The new OID database uses the same string names as
995 before but the 'protocol' is gone. There are now only two representations
996 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
997 converts from string to OID; functions with prefix yaz_oid_to_string
998 converts the other way.
1000 Change to emit_term() in CQL-to-PQF query translation: when a term has
1001 the /regexp relation modifier, do not process it for leading and
1002 trailing "^" and "*", which have quite different meanings in regular
1005 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1006 write handlers no longer carries a 'last' parameter. This will make
1007 yaz_iconv flush "less" characters. A flush is performed by call to
1008 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1010 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1011 removed, because function yaz_query_to_wrbuf does the same.
1013 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1014 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1016 Deprecated MARC utility functions removed.
1018 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1021 Branch split: YAZ_2_1_55_branch
1023 --- 2.1.54 2007/03/16
1025 Fix to ZOOM-C so that transparent reconnection is properly handled on
1026 connections that are in asynchronous mode.
1028 Fixed compilation on OpenBSD 4.0.
1030 Large strings in GRS-1 records are now properly displayed in yaz-client.
1032 Added character conversion support for "advancegreek"; based on patch from
1035 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1036 sequence is met. Before the error was not set so it would be unknown.
1038 Adjust yaz-marcdump MARC reader so that it skips until record separator
1041 --- 2.1.52 2007/03/07
1043 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1044 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1045 fd_set structure used as a bitmask for the FDs to be selected on.
1047 Using ACX_PTHREAD macro to check for POSIX threads.
1049 Fixed have-vsnprintf check.
1051 --- 2.1.50 2007/02/23
1053 Fixes for configure on BSD. Bug #900.
1055 Added snprintf/vsnprintf wrappers for systems that don't have
1056 limits (heavens forbid).
1058 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1059 created before all previous tasks were completed and removed from the
1060 task queue, the new task could be removed by a mistake.
1062 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1064 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1066 Fixed bug #832: Problem with MARC/charset in yaz-client.
1068 Fixed bug #668: save command line history for yaz-client.
1070 Fixed bug #830: pkg-config support.
1072 --- 2.1.48 2007/01/23
1074 Extended ZOOM result set options with two options that may be read by
1075 a client: resultSetStatus and presentStatus with values as specified for
1077 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1079 Fixed bug #827: Using SSL fails on Debian etch.
1081 Fixed bug #826: Weird looking chars for set of MARC records.
1083 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1084 that is treated as an ItemOrder with itemRequest being an XML document
1085 external. The value of "doc" is the content.
1087 Extended the GFS search facility. New member of bend_search_rr
1088 'estimated_hit_count' signals that hits is known to be an estmate
1089 (higher or lower than real hit count). New member 'partial_resultset'
1090 signals that the search was partial (hit count is lower or equal than
1091 real hit count). For Z39.50, the information is stored in resultSetStatus
1092 member of SearchResponse APDU. For SRU, the information is signalled
1093 via SRU diagnostic 59: "Result set created with valid partial results
1096 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1098 --- 2.1.46 2007/01/13
1100 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1102 Added ZOOM_connection_peek_event.
1104 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1105 the following new functions:
1106 ZOOM_event_nonblock, ZOOM_connection_process,
1107 ZOOM_connection_get_{socket,mask,timeout},
1108 ZOOM_connection_fire_event_{timeout,socket}.
1109 The existing blocking event handler, ZOOM_event, is a wrapper for the
1110 + blocking ZOOM_event_sys_{poll,select}.
1112 Implemented function ccl_xml_config which parses XML version of CCL
1113 configuration (bug #798).
1115 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1117 Added timings utility (yaz/timing.h)
1119 --- 2.1.44 2007/01/03
1121 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1124 Fixed bug #779: Rotation of apdu.log fails.
1126 Fixed for character set conversions:
1127 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1128 Honor G1 set in MARC-8 decoding.
1130 --- 2.1.42 2006/12/17
1132 Fixed bug #775: char conversion does not handle Alternative UTF-8
1135 Implemented function yaz_marc_read_line which parses MARC line format
1136 records. There is a wealth of formats out there. So far, this function
1137 reads line records produced by yaz_marc_write_line.
1139 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1140 more generic and easier to remember(!) options: -i format and -o format
1141 which specifies input format and output format respectively - where
1142 format is one of "marc", "marcxml", "line", "marcxchange".
1144 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1145 does not print anything except warnings for records.
1147 For yaz-marcdump, added support for MARC split into files (-s) with a given
1150 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1151 spec, at http://www.loc.gov/standards/sru/record-update/
1152 This has changed the binary layout of the following structs:
1153 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1154 bend_update_rr . Patch by Ko van der Sloot.
1156 Added GFS utility function bend_assoc_is_alive which returns 1 if
1157 association is still alive (client is connected); 0 otherwise (client
1158 closed connection). This allows busy servers to stop working for
1161 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1162 been a separate piece of software. This version of ziffy has been modified
1163 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1165 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1167 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1168 Client code may now interrogate options such as "init_opt_sort" to
1169 find out whether the server claims to support various options.
1171 --- 2.1.40 2006/11/27
1173 Added utilities yaz_{set,get}_esn to set/get element set name from
1176 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1177 of YAZ and has been so since YAZ 2.1.10.
1179 Implemented ZOOM_record_error which returns error information for
1180 record (surrogate diagnostic).
1182 --- 2.1.38 2006/10/31
1184 Updates for SRU Update by Ko van der Sloot:
1185 1. Changed name from "operation" to "action"
1186 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1187 versions in the code, marked as 'backward compatible'.
1188 3. Added diagnostics for SRU Update.
1190 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1192 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1194 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1196 For GFS, fixed problem with SRU diagnostic 'First record position out of
1197 range' being issued for 0 hits.
1199 zoomtst10 part of Windows Build.
1201 --- 2.1.36 2006/10/13
1203 Implemented yaz_filepath_comp which splits a path into file path
1204 components (required by Zebra 2.0.3+).
1206 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1207 BSD inspired license until now so this should not have any real impact on
1208 anybody. See http://www.opensource.org/licenses/bsd-license.php
1210 Fixed bug #687: Missing log lines.
1212 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1215 Fixed bug #689: SRU diagnostics to be added.
1217 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1218 whether a connection is idle (no more work do do).
1220 --- 2.1.34 2006/10/04
1222 Change type of optval from long to int for invocation of setsockopt with
1223 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1225 Added support for specifying the max log file size for the Generic
1226 Frontend Server. The size is given with option -r.
1228 --- 2.1.32 2006/09/21
1230 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1232 --- 2.1.30 2006/09/17
1234 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1237 Fixed bug in Generic Frontend Server that could cause a server to stop
1238 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1240 For the generic frontend server, the maximum record size is used as maximum
1241 size of incoming packages (SRU + Z39.50). The value until was previously
1242 only used in Z39.50 Init negotiation and, later, in a session controlled
1243 sizes of records returned. This is controlled using -k option. It can be
1244 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1246 --- 2.1.28 2006/09/04
1248 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1251 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1253 New option for yaz-marcdump -lpos=value which allows setting a portion
1254 of MARC header to a certain value.
1256 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1258 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1259 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1261 --- 2.1.26 2006/08/15
1263 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1266 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1268 --- 2.1.24 2006/08/08
1270 Fixed MARC ISO2709 encoding routines to deal with character set
1273 Minor changes to GFS logging. Database included in search request log
1276 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1277 cached/multiple records.
1279 Shared libraries are built by default on Unix+configure.
1281 Changed cql2pqf transformation to use a different evaluation order. The
1282 new order is: always, relation, structure, position, truncation, index
1283 and relationModifier. Old order was: always, relation, relationModifier,
1284 structure, index, position, truncation. Note that the the latter ones
1285 override former ones for identical attributes.. The new scheme means that
1286 it is possible to override any existing attribute with a relationModifier.
1287 And also that it is possible to override everything for the index rule
1288 (except the ones listed in relationModifier). No order is perfect but this
1289 one, we believe, covers more real cases.. The "always" should have been
1290 called "default", since the attributes there can be overridden with all
1293 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1294 compilation phase, but also for yaz-config --cflags output. This allows
1295 us to have public headers with Libxml2 stuff in them . It should also,
1296 eventually, make Libxml2 checks redundant in packages using YAZ, such
1299 --- 2.1.22 2006/06/15
1301 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1302 stored in uri, message and details.. Previously diagnostics were stored
1303 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1304 compatibility.. but he's probably the only one affected, so.
1306 Added support for CCL, compiled on the client side, in ZOOM-C. This
1307 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1308 input; the resulting query objects can be used for for searching with
1309 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1311 YAZ' configure searches for OpenSSL by default.
1313 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1314 SL_CTX_use_certificate_file. See
1315 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1316 for more info. Thanks to Ko van der Sloot.
1318 --- 2.1.20 2006/06/02
1320 Bug #600: SRU GET, POST support for yaz-client. Introduced
1321 command 'sru' which selects method SOAP/GET/POST.
1323 Allow missingValueAction to be specified for the sortspec string -
1324 function yaz_sort_spec. By default, the missing value action is null.
1325 Use ! to specify "abort". Use = followed by stringvalue to specify default
1328 Ensured that Present-handler (if defined) is called in GFS before any call to
1329 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1330 searchRetrieve requests.
1332 Documentation for YAZ is now based on the Docbook XML/XSLT using
1333 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1334 is no longer depending on jade/openjade or docbook-to-man scripts.
1335 PDF is no longer part of the distribution - but can optionally be
1336 made using DSSSL/jadetex or FOP.
1338 Added retrieval handling support in Generic Frontend Server to support
1339 conversion between MARC/XML as well as XSLTtransforms. See
1340 etc/yazgfs.xml for an example.
1342 Added Authentication support to Generic Frontend Server in SRU
1343 mode. Authentication using HTTP Basic is supported, as is the use
1344 of 'x-username' and 'x-password' parameters in the request itself.
1346 Added support for a new character set MARC8s identical to MARC8 except
1347 that it converts combined characters to single Unicode characters in the
1348 Latin-1 range (when possible).
1350 --- 2.1.18 2006/04/24
1352 ASN.1 compiler 0.4: generates brief Doxygen file header for
1353 generated .h/.c files.
1355 Utility yaz_iconv now supports conversion to MARC-8.
1357 New facilities for the MARC module. The reading - and writing of
1358 content are separate methods for the yaz_marc_t handle. The following
1359 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1360 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1361 format). Write functions have prefix yaz_marc_write_.. The existing
1362 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1363 available. Removed support for OAI-MARC and simplexml (not the
1364 simplexml from PHP5).
1366 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1367 to be returned for this connection.
1369 --- 2.1.16 2006/03/31
1371 Allow multiple languages and charsets to be specified with
1372 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1373 negcharset iso-8859-1,utf-8
1375 Translation of proximity nodes from CQL into PQF now works.
1377 Moved to automake 1.8, 1.9.
1379 Added function yaz_log_set_handler which allows a log handler to be
1380 installed. This handler will be called for all log messages. Output
1381 to file is also produced; but that can be disabled by passing NULL
1382 fname to yaz_log_init_file.
1384 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1386 For SRW (including GFS), accept application/soap+xml as content-type
1389 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1390 produces NO stylesheet reference even if a default stylesheet is specified
1393 --- 2.1.14 2006/03/14
1395 Updated Windows package to include yazd.dll + yazd.lib for the
1396 Development component.
1398 If the environment variable YAZ_LOG is set, then it is used as a
1399 string indicating the default level of logging to use if not
1400 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1401 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1402 used as before. So, for example, to omit warnings from YAZ logging,
1403 export YAZ_LOG=-warn
1405 cql_transform() now map structure and other attributes before indexes,
1406 so that index-specific structures and other attributes can override
1407 defaults. So now a combination of mapping specifications such as:
1409 index.dc.date = 1=date-modified 4=5
1410 does the right thing.
1412 cql_transform() now also respects the "always" mapping specification,
1413 which establishes an initial set of attributes to be used for all
1414 terms except where overridden by more specific attributes associated
1415 with the index, relation or modifier.
1417 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1418 which mode to use; one of "post", "get" or "soap" (SRW, default).
1420 Fixes for yaz_iconv routines: changed trie-based character set conversions
1421 to use only non-negative values for bit fields due to Sun's C compiler not
1422 supporting negative values.
1424 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1425 sequences where not read correctly. Fix by Rustam Usmanov.
1427 Updated win/makefile to use options, settings which makes things
1428 compile with VS C 2005.
1430 --- 2.1.12 2006/02/01
1432 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1434 In ZOOM socket code, use select instead of poll on MacOSX.
1436 ZOOM-C now support client-side compilation of CQL into RPN that is
1437 sent to the server, enabling CQL to be used against all Z39.50
1438 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1439 ZOOM_query object, and submit it using ZOOM_connection_search().
1440 The CQL-to-RPN translation uses a configuration file, the name of
1441 which must be specified in the Connection's "cqlfile" option.
1443 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1444 function, which takes as its start-term parameter a ZOOM_query object
1445 (which may have had either CQL or RPN set into it).
1448 --- 2.1.10 2005/11/29
1450 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1451 GFS to support this as well. Backend handler, bend_srw_update, does the
1452 update work. Code contributed by Ko van der Sloot.
1454 Allow retrieval of Search Result-1 information in ZOOM by the use of
1455 options that are attached to a result set. ZOOM documentation updated
1458 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1459 UTF-8 conversion. Patch by Raj Patel.
1461 Added option -m to GFS to control formatting of timestamps in log file.
1463 Added 'exit' as synonym for 'quit' in yaz-client
1465 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1466 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1467 for the new members. Patch by Ko van der Sloot.
1469 Added support for SRU POST. It is supported for content-type
1470 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1472 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1473 Instead make the library libyaz.la multi-threaded. Threading as a whole
1474 can still be disabled by configure option --disable-threads. Previosly,
1475 with older GLIBCs there were problems with MT libs under Apache. This
1476 has now been fixed a long time ago.
1478 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1481 CQL module modified to be case insensitive for relations/indexes/operations.
1483 Fixed bug in CQL transform code: incorrect value relationModifieder
1486 Added 'show all' command for yaz-client which retrieves all results
1489 Added new yaz-client, xmles, which takes a (private) OID and
1490 a document to be sent as an extended service request.
1492 Describe new yaz-client commands wait_response and set_auto_wait.
1494 Increase TCP/IP listener backlog from 3 (which I am guessing was
1495 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1496 that the socket will queue as many incoming connections as it's able
1497 to handle ongoing connections. In other words, it will never now
1498 refuse a connection that it would be able to handle merely because
1499 it's not got around to accepting() enough of the pending connections
1500 yet. This is the behaviour anyway under Linux, where the listen()
1501 argument is ignored; but not under BSD and on systems such as
1502 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1503 YAZ-based servers should now be uniform across operating systems in
1506 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1507 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1508 This allows yaz-marcdump to read large MARC batches (>2 GB).
1510 Modified all YAZ source files - except the source which is auto-generated
1511 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1514 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1515 corresponding to the existing *_setl() function. These allow option
1516 values containing arbitrary valuues.
1518 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1519 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1520 except that it returns an indicator of whether or not the sort
1521 criterion was accepted (0 for OK, -1 for invalid).
1523 --- 2.1.8 2005/06/07
1525 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1526 MARC output rather than returning "new" buffer.
1528 yaz-client warns about unknown init options.
1530 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1532 --- 2.1.6 2005/05/24
1534 Added support for SRW sort in Generic Frontend Server. Patch
1535 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1536 sortKeys - or NULL if none is provided.
1538 Fixed bug #307: It was impossible to specify indefinite/no timeout
1539 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1542 Added support for multiple languages and charsets to be specified in
1543 ZOOM. Each charset/language is separated by a blank. If negotiation is
1544 in effect in init-response, Option
1545 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1546 Code based on patch by Vasiliy Osadchuk.
1548 Fixed bug #306: infinite recursion that occurred when calling
1549 yaz_log_level_init as the first call (before other log level or
1552 Fixed bug in scan handling in front end server: if preferred-Position-In-
1553 Response was non-present, a NULL pointer referece was performed.
1555 --- 2.1.4 2005/04/26
1557 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1558 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1559 now defined for all those error codes. So instead of putting 109 in
1560 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1561 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1563 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1566 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1568 Program yaz-client now exits and produces an error message if multiple
1569 Z39.50 servers are specified on the command line (none or one allowed
1572 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1575 --- 2.1.2 2005/03/16
1577 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1579 Fixed bug #272: Preserve spacing for CCL terms.
1581 --- 2.1.0 2005/03/14
1583 Added support for virtual hosts and multiple backend servers for
1584 the YAZ frontend server. The configution is XML based and
1585 support specificition of CQL to RPN mappings and explain information.
1586 See section "Virtual Hosts" in the YAZ manual.
1588 Extended OPAC display utility. OPAC display utility renders
1589 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1590 to supplement yaz_marc_decode_wrbuf.
1592 Fixed a bug in MARC decoder that could caused it to crash for some
1593 invalid MARC records. More diagnostics and warnings where added in
1594 XML output (warnings, etc are stored in comments).
1596 --- 2.0.34 2005/02/08
1598 Fixes for UNIX domain sockets. Bug #261.
1600 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1602 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1603 Added yaz_marc_subfield_str which defines subfield lead string which is
1604 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1605 yaz_marc_endline_str which defines end of fields string used in
1606 YAZ_MARC_LINE format. Default string is newline.
1608 Experimental support for MarcXChange. This format can be produced
1609 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1610 http://www.bs.dk/standards/MarcXchange.xsd
1612 Added yaz-client commands scansize that sets maximum number of
1613 entries to be returned by scan.
1615 --- 2.0.32 2005/01/11
1617 Added support for SRW scan in yaz-client and Generic Frontend Server.
1619 * Added whereInList member to SRW Scan Term.
1621 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1623 Fixed NMEM system to return aligned blocks on the smallest boundaries
1624 that are suitably aligned for all possible types on the particular
1625 architecture YAZ is being built for.
1627 --- 2.0.30 2005/01/04
1629 Fixed numerious warnings that was issued with newer versions of GCC.
1631 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1632 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1635 Make YAZ Generic Frontend Server slightly faster.
1637 Enhance (and reduce) logging for Generic Frontend Server.
1639 Revert YAZ log system so that it flushes every write operation
1640 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1642 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1643 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1644 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1645 will effectively disable old definitions.
1647 --- 2.0.28 2004/11/09
1649 Added yaz_log_time_format which specifies log format using
1652 Added yaz_log_module_level which returns mask for a module. Value
1653 is non-zero mask a if module is enabled; zero if disabled.
1655 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1656 in include/yaz/cql.h.
1658 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1660 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1662 Fixed bug #172: RPM builds does not enable SSL.
1664 Doxyfile.in part of dist. Doxyfile generated by configure.
1666 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1667 are given and the corresponding component does not exist.
1669 Extend CCL documentation in YAZ reference. Describe r=r.
1671 --- 2.0.26 2004/10/01
1673 Fixed MARC->MARCXML conversion to properly deal with
1674 fields, subfields, indicators having non-ASCII characters.
1676 Fixed MARC->MARCXML conversion so that ASCII control characters
1677 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1680 Added YAZ GFS support for conversion from Z39.50 surrogate
1681 diagnostics to SRW surrogate diagnostics.
1683 Bug fix: YAZ GFS did not return schema in explainResponse.
1685 --- 2.0.25 2004/09/30
1687 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1688 now converts recordSchema to elementSetName as well as schema URI.
1690 Fixed bug in COMSTACK that prevented HTTP request packages from being
1693 --- 2.0.24 2004/09/29
1695 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1696 does not require white-space before and after the dash in a range, e.g.
1697 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1700 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1701 due to new GCC removing "redundant" code.
1703 Added yaz-client commands scanpos and scanstep that sets preferred
1704 position and step-size for scan.
1706 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1708 Added CCL utility ccl_qual_buf which parses one or more CCL
1709 spec lines in a buffer.
1711 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1712 of name and value - ignoring empty lines and comments.
1714 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1716 Added odr_get_element_path which returns current element path for an
1717 ODR handle. This utility is useful in error handling or user-defined
1720 Added ODR_PRINT utility odr_set_stream which is is a more generic
1721 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1722 to a write function and pointer to close function. The close function - if
1723 non-NULL - will be called during odr_destroy.
1725 Fixed bug in CCL parser where truncation char was not removed from
1726 right side when truncation=both was in effect.
1728 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1731 --- 2.0.23 2004/08/11
1733 Fix buffer overrun in CQL parser when dealing with proximity (%).
1735 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1736 to UTF-8/UCS conversion is now only based on codetables.xml.
1738 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1740 --- 2.0.22 2004/08/06
1742 Add support for more "commit changes" in ZOOM (uses Extended Services).
1744 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1747 Yet another small fix for configure of SSL.
1749 --- 2.0.21 2004/05/14
1751 Fix SSL libs for configure when --with-openssl=DIR is given.
1753 --- 2.0.20 2004/05/10
1755 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1757 SSL comstack now uses yaz.pem certificate file on server side
1758 by default. Certificate filename can be configured by calling
1759 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1761 Fix bug regarding multiple calls to ZOOM_connection_connect.
1763 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1765 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1766 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1768 ZOOM now allows inspection of X509 peer certificate for verification.
1769 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1771 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1772 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1773 as "modular" but it simplifies things.
1775 Added cs_get_peer_certificate to that returns peer X509 PEM.
1777 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1778 NULL if SSL is unavailable.
1780 Documentation about MARC decoding tools.
1782 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1784 --- 2.0.19 2004/03/30
1786 Rename CHANGELOG to NEWS to follow GNU style packing.
1788 Fix bug with missing initialization of member in init_diagnostics.
1789 This bug affects threaded version of GFS server.
1791 --- 2.0.18 2004/03/20
1793 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1796 Ensure zlib.dll is packed with Windows install.
1798 --- 2.0.17 2004/03/17
1800 Fix encoding of xsd:string to use text instead of CDATA.
1802 Fix endless loop in CQL parser with unbalanced ".
1804 Use a more compact way to store MARC-8 conversion tables.
1806 --- 2.0.16 2004/03/16 Debian only
1808 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1811 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1816 --- 2.0.15 2004/03/01
1818 Another fix for decoding of XML packed records.
1820 --- 2.0.14 2004/02/25
1822 Fixes for Chunked encoding. White space not ignored after length spec.
1824 Update NS and use default NS for SRW diagnostic elements.
1826 --- 2.0.13 2004/02/23
1828 Implement ZOOM_resultset_cache_reset which resets record cache.
1830 Implement ZOOM_resultset_sort which sorts a result set.
1832 Implement chunked HTTP transfer.
1834 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1836 --- 2.0.12 2004/02/16
1838 Added member 'schema' to bend_explain_rr structure so that backend
1839 can specify explain record identifier. Defaults to Zeerex 2.0.
1841 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1843 --- 2.0.11 2004/02/16
1845 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1848 Added init command for yaz-client which sends "extra" init request.
1850 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1851 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1853 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1855 Make ZOOM error code for "invalid query".
1857 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1859 --- 2.0.10 2004/02/05
1861 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1864 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1866 Added option -p <file> to make Generic Frontend Server to write PID file.
1868 Added option -D to put Generic Frontend Server in background on its own.
1870 Make ZOOM C recognize option "password". If unset, "pass" is used
1871 (for backwards compatibility).
1873 Fixed a bug in Generic Frontend Server that could make it crash if a
1874 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1877 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1878 Must be issued before open, in order to be in effect.
1880 --- 2.0.9-6 2004/01/12 Debian/Windows
1882 Make the SRU server more picky WRT unknown params, etc.
1884 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1886 New YAZ client command, options, that sets Z39.50 options.
1888 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1889 options from a string of tokens (one token for each option bit).
1891 Update SRW diagnostic code messages.
1893 --- 2.0.9-5 2004/01/07 Debian/Windows
1895 Handle user defined stylesheet for SRW/SRU.
1897 --- 2.0.9-4 2004/01/06 Debian/Windows
1899 Fix bug in decoding of Content-Length.
1901 --- 2.0.9-3 2004/01/06 Debian/Windows
1903 Fix a bug with decoding of XML packed records.
1905 --- 2.0.9-2 2004/01/05 Debian only
1907 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1909 Fix bug in SRW/SRU diagnostics decoding.
1911 --- 2.0.9 2004/01/05
1913 Fixed bug in Generic Frontend Server which could drop records exceeding
1914 preferred message size. Reported and fixed by Irina Dijour.
1916 Fixed calculation of package size for structured records in Generic
1917 Frontend Server. Reported and fixed by Irina Dijour.
1919 Fixed namespace for SRW/SRU diagnostics.
1921 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1923 --- 2.0.8 2003/12/22
1925 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1926 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1929 CQL changes to reflect recent changes to the specification:
1930 * Documentation talks about context sets instead of index sets.
1931 * Documentation talks about indexes instead of qualifiers.
1932 * The CQL-to-PQF transformer's configuration file now uses
1933 "index.set.name = <attributes>" instead of the old form
1934 "qualifier.set.name = <attributes>". (Both forms are still
1935 understood but the latter is deprecated.)
1936 * CQL terms with no explicit index specified are now interpreted as
1937 cql.serverChoice instead of srw.serverChoice (which of course
1938 behaves exactly the same.)
1940 --- 2.0.7 2003/12/16
1942 MARC conversion can now generate ISO2709 output in another
1943 character set. yaz-marcdump uses this facility if you invoke it
1946 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1947 functions from there can be used from C++.
1949 --- 2.0.6 2003/12/04
1951 Frontend server now transfers memory from decoded packages to stream
1954 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1955 references to show up.
1957 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1958 the ZOOM Abstract API. The older names for the same options are still
1959 also supported for the benefit of old applications.
1961 ZOOM-C supports "implementationId" and "implementationVersion" options
1962 to go along with "implementationName". These allow the user code to
1963 specify identification strings to be sent to servers.
1964 Add OID for the new ExtLite attribute set.
1966 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1967 as requested/supplid by Ere Maijala <ere@atp.fi>
1969 For generic frontend server, reverse the order of
1970 "toolkit-supplied / application-supplied" strings sent as implementationId,
1971 Name and Version. Also, remove the spaces around the slash. This brings
1972 the GFS in line with the behaviour of ZOOM-C on the client side.
1974 Add function ZOOM_scanset_display_term.
1976 yaz-client shows scan displayTerm if present.
1978 Utility yaz-iconv is now installed by default along with the man page
1981 Extend configure check for OpenSSL to use pkg-config where available (such
1984 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1985 server to specify uid/gid/mask for socket using the format
1986 unix:[user=uid,][group=gid,][umask=mask,]file=path
1987 If file= is omitted the existing format is assumed, e.g.
1989 in which case the mask is 0666 (rw for everybody).
1991 Major restructure of YAZ source. All source in libyaz is in src directory.
1992 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1993 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1995 Added man page for utility yaz-marcdump (used to be called marcdump).
1996 yaz-marcdump is installed by 'make install'.
1998 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1999 of incoming package failed.
2001 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2003 Change prototype of odr_perror: add const to message string.
2005 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2007 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2008 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2009 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2010 DNS lookup. There should not be any compatibility problems with this
2011 assuming that blocking=1 or 0 is used.
2013 Fix bad reference in UNIX comstack in function cs_addrstr.
2015 Fix for compilation on AIX.
2017 The generic front-end server (server/seshigh.c) now supports returning
2018 Init diagnostics to the client in User-information-field, in
2019 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2022 --- 2.0.4 2003/09/04
2024 Allow any CQL relation (not just all,any,exact,scr).
2026 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2027 that features the same UI.
2029 Implemented command update0 in YAZ client which is equivalent to
2030 update but uses old of Ext Update ASN.1.
2032 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2033 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2034 Previously no OID was used for this info.
2036 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2037 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2038 returns 'malformed search term' otherwise.
2040 SortResponse member resultCount now set to NULL in sort handler of
2043 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2046 Add three new utility functions for translating OIDs between various
2047 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2048 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2049 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2050 char *oid_to_dotstring(const int *oid, char *oidbuf);
2051 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2053 Reverted modifications for ES Update definition for z_IU0Update
2054 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2055 is back to YAZ 2.0.2.
2057 String value attributes for CCL parser.
2059 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2060 which their FirstSearch server returns in Init responses, sometimes
2061 carrying useful diagnostic information when Init fails. This has the
2062 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2063 "z39.50/oclcui.asn", where its definition is somewhat different from
2064 what OCLC document on their web-site, as required to interoperate with
2067 Support for anonymous authentication in yaz-client. Use the command
2070 * Fix the OID of the Index Data-local "admin" Extended Service from
2071 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2072 the 1000, which indicates a locally-defined OID, was a mistake.
2074 --- 2.0.3 2003/06/20
2076 Fix CCL directive @case handling so that it affects string match for
2077 both CCL keywords and qualifiers.
2079 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2080 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2081 Decoder has been updated with ASN.1 changes as listed in
2082 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2083 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2084 z_IUUpdate, remains unchanged.
2086 ZOOM_record_get may now return a record in a specific character set.
2087 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2088 "from" is the character set of record as returned by target. "to" is
2089 the character set to be returned. If omitted, "to" is UTF-8.
2091 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2093 New ODR utility, odr_getelement, which returns name of element for
2094 which encoding/decoding failed.
2096 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2097 in cases where a required element was omitted.
2099 Bug fix: some MARC8 sequences were not converted.
2101 New ZOOM option "step" which specifies number of records to be
2102 retrieved in one chunk. Used in conjunction with "start" and "count".
2104 SRW support for yaz-client. Use scheme http: to use it, e.g.
2107 yaz-client no longer does (un)intelligent character set conversions
2108 by default. Can be enabled with charset and marc_charset commands.
2110 xmalloc trace fix for 64-bit systems such as DEC alpha.
2112 Solaris 2.6 compile fix.
2114 New function, cql_strerror() translates SRW error codes, as returned
2115 by cql_transform_error(), into human-readable English strings. Used
2116 in yaz-client diagnostics when appropriate.
2118 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2119 converts it into a type-1 query which is sent to the server. This
2120 makes CQL available for use with all Z-servers, as opposed to the tiny
2121 minority that can handle CQL queries themselves.
2123 --- 2.0.2 2003/04/28
2125 New Debian package layout similar to the Redhat Package layout.
2127 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2128 and search result respectively.
2130 --- 2.0.1 2003/04/25
2132 Redhat package is now several packages: libyaz (runtime libraries),
2133 libyaz-devel (development and documentation, and yaz (utility programs).
2134 Package spec file by Morten Bogeskov.
2136 New member 'schema' in struct bend_fetch_rr which the name of requested
2137 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2138 handler MAY set this to reflect the schema of the returned record.
2140 New member 'display_term' in struct scan_entry. GFS now sets member entries
2141 and allocates scan entries to be filled by user scan handler. In previous
2142 version, entries member was allocated by the scan handler. That still works,
2143 but the GFS will ignore member display_term - assuming it was NOT set by
2144 the handler. The fact that the GFS now allocates the entries both allows
2145 for new members and makes a scan handler easier to write.
2147 Fix CQL lex buffer overflow.
2149 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2150 SRU default recordPacking is string.
2152 SRU protocol support for frontend server.
2154 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2156 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2158 Added scan for the ZOOM shell (zoomsh).
2162 * String Identifers for Schemas (Amendment 5).
2163 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2164 Old definition for schema
2165 Odr_oid *schema; /* OPT */
2170 Z_InternationalString *uri;
2171 #define Z_Schema_oid 1
2172 #define Z_Schema_uri 2
2175 * resultCount parameter to Sort Response (Amendment 1).
2176 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2178 Support for SRW 1.0 over HTTP. This is an optional feature and
2179 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2182 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2183 on the same port. SRW SearchRetrieveRequests are mapped
2184 to bend_init,bend_search,bend_fetch,bend_close.
2186 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2188 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2189 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2191 ZOOM connections are SRW based if schem http is used for hostname
2192 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2193 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2195 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2196 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2197 distance=n, order=true/false, relation=le, prox unit=word. If
2198 n is omitted, distance 1 is used.
2200 Fixed problem with C compiler include path in wrong order.
2202 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2203 on Solaris. Patch from Ko van der Sloot.
2205 New MARC decode API. All new functions operate on a yaz_marc_t
2206 handle. The most important new functions are: yaz_marc_create,
2207 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2208 decode and destroy respectively. Decoder can produce formats
2209 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2210 include/yaz/marcdisp.h.
2212 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2213 to UTF-8, UCS-32, wchar_t or Latin-1.
2215 * Prototypes for yaz_iconv_-functions moved to separate header
2216 include/yaz/yaz-iconv.h.
2218 Make a few private functions 'static' in unix.c. This prevents
2219 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2221 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2222 are set when Init Response is received.
2224 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2225 but returns diagnostic set as well.
2227 New function yaz_strerror which is a portable wrapper for
2228 strerror/strerror_r/GetLastMessage.
2230 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2231 is returned for MARC. If type is "oai", then OAI MARC is returned.
2233 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2236 --- 1.9.2 2002/11/26
2238 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2240 Fix bad race conditions on SIGTERM and terminate gracefully in
2243 Move retrieval (data1) module to Zebra since nobody seems to be
2246 Add GRS-1 render for ZOOM using same format as yaz-client.
2248 --- 1.9.1 2002/10/05
2250 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2252 Fix broken ESpec handling in data1 module.
2254 SGML reader parses comments and makes them part of the data1 tree.
2256 Added several type casts so that YAZ compiles as C++ code.
2258 ZOOM didn't handle PDU encoding failures properly.
2260 Added more Bib-1 diagnostics (approved extensions).
2262 GNU configure: better check for iconv.
2264 More portable use of accept, getpeername. Check for socklen_t. Use
2265 int/size_t if socklen_t is not defined.
2269 PQF parser rejects bad queries - including those with extra
2270 characters in them. PQF parser used to silently ignore that.
2271 Cleaner API for PQF added, which allows you to get detailed
2272 error information for bad queries (see yaz/pquery.h).
2274 Fixed bug in ZOOM_record_get for type "database".
2276 Implemented mini iconv library supporting conversions between
2277 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2279 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2281 --- 1.8.9 2002/08/20
2283 Fixed ZOOM C record cache so that preferredRecordSyntax and
2284 elementSetName is used to check for already fetched records.
2286 --- 1.8.8 2002/08/02
2288 Added three members in bend_initrequest structure to facilitate
2289 character set negotiation.
2291 Fixed a bug in frontend server that could cause indefinite
2292 loops under rare conditions.
2294 Revised character set utilities (charneg.h) so that encoding
2295 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2297 For PQF, directive @term <type> sets term type for Scan/Search.
2298 Here <type> is general, string, numeric, null. The term type
2299 is inherited - just like @attr.
2301 New call odr_set_charset that sets character set conversion for
2302 international-strings on a ODR stream. Prototype is:
2303 int odr_set_charset(ODR o, const char *to, const char *from);
2304 The InternationalString is still represented as C string in YAZ
2305 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2306 won't). On the protocol level, you can use any encoding.
2308 Support for UNIX sockets in ZOOM.
2310 Solaris recv sometimes returns errno == ENOENT. It is treated as
2311 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2313 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2314 both client and server. Code by Morten Bogeskov.
2316 --- 1.8.7 2002/05/22
2318 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2319 that they can be used directly from Visual Basic. You must recompile
2320 your windows APP if you're using ZOOM.
2322 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2323 Commands "lang" and "charset" sets language and character set respectively.
2324 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2325 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2327 Attributes from multiple CCL fields may be OR'ed rather than merged
2328 using directive "@field or". Fields are still merged by default -
2329 equivalent to "@field merge".
2331 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2334 Fixed bug in zget for parameter ExtendedServicesResponse.
2338 --- 1.8.6 2002/03/25
2340 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2342 Client displays USR.1:SearchResult-1 (hits per term).
2344 Additional Search Info for search in Generic Frontend Server.
2346 Fixed CCL parsing of "field=s".
2348 WIN32 installer - using the excellent NSIS software from nullsoft.
2350 Fixed CCL parsing of "field = - <number>".
2352 Added function yaz_marc_decode that decodes MARC for line mode
2353 display or XML (similar to that used by JZKit).
2355 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2356 Z39.50. But ISO/ILL was, however.
2358 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2359 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2361 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2362 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2364 --- 1.8.5 2002/02/03
2366 New YAZ client features: Command completion and new commands:
2367 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2368 Code provided by Jacob Poulsen.
2370 New call oid_trav, that visits all registered OIDs via callback.
2372 Function ZOOM_record_get now returns const char pointer rather than
2373 void pointer. It saves a lot of type casts.
2375 For YAZ client, command "auth" now allows you to set authentication
2376 in IdPass style. It is enabled when three tokens are given - order
2377 is user, group and password.
2379 Fix memory leaks in MARC record handling for ZOOM.
2381 New option for YAZ client, -k <kilobytes> that sets
2382 maximum record size. Similar to -k option for generic frontend
2383 server and yaz-ztest.
2385 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2387 Prefix query parser reports "fail" when bad attribute set is given.
2389 Fix in MARC decoder. Proximity logging. Fix for attribute set
2390 in scan handler for server. Patches by Shigeru Ishida.
2392 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2395 Configure option --with-openssl=<dir> now works when a directory is
2396 specified. Patch provided by Morten Bogeskov.
2398 New option for YAZ client, -u <auth>, that sets authentication.
2400 ZOOM fix: error information was sometimes "missing", since error
2401 was cleared/reset too when it shouldn't.
2403 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2405 --- 1.8.4 2002/01/04
2407 Scan for ZOOM API. New object ZOOM_scanset. New functions
2408 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2409 ZOOM_scanset_destroy.
2411 New ZOOM function, ZOOM_connection_last_event, that returns type
2412 of last event (such as "receive data", "send data", "apdu received",
2415 New ZOOM option, schema, that specifies schema for retrieval.
2417 New CCL feature. Qualifiers can be aliases for one or more
2418 other qualifiers (if more than one is given, OR is used).
2420 ZOOM uses named result sets if target supports it.
2422 Two new YAZ client commands: . (dot, which sources a script of YAZ
2423 client commands), and ! (to execute shell command.). Implemented
2426 Working on Debian packages.
2428 --- 1.8.3 2001/11/19
2430 YAZ client enables named result sets only if target supports it.
2432 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2434 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2435 with key="host" to get same result.
2437 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2438 Function Z3950_resultset_record(s) returns references to records
2439 "owned" by resultset. To become owner use Z3950_record_clone.
2441 Function z_ext_record handles Extended Services. Thanks to
2444 --- 1.8.2 2001/11/12
2446 CCL Parser fix: ignore token comma when dealing with and-lists.
2448 Documentation updates for COMSTACK.
2450 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2451 Changed prototype Z3950_records. For some functions, int parameters
2452 were changed to size_t.
2454 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2457 New MARC decode/display function, marc_display_exl, which properly rejects
2458 non-ISO2709 records. YAZ client uses it.
2460 --- 1.8.1 2001/10/29
2462 Fix bug: local attribute set wasn't set correctly in PQF strings.
2466 * Old Z39.50 codecs no longer supported.
2468 Added ZOOM C binding. See http://zoom.z3950.org/
2470 Renamed states for COMSTACKs to avoid confusion with events.
2472 Implemented cs_look and proper cs_rcvconnect.
2474 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2476 Configure detects POSIX threads on OpenBSD.
2478 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2479 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2481 When error is returned from present handler, non-surrogate diagnostic
2482 is returned in present response (and fetch handler is no longer called).
2484 * Minor adjustments to pquery parser (PQF). Token characters may be
2485 escaped by using backslash (C-style).
2487 PQF parser allows string attribute values to be specified. For @attr,
2488 non-numeric characters after the equal-sign are treated as strings
2489 (e.g. @attr 9=title).
2491 CCL trunction character may be defined (@truncation in file)
2493 * function zget_ExtendedServicesRequest sets waitAction to
2494 waitIfPossible (was wait).
2496 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2499 CCL operator names may be set in field definition files (CCL_bibset).
2500 See ccl/bib1 for an example.
2502 Fixes in ASN.1 compiler for C++ compatibility.
2504 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2505 and "op_or" to avoid conflict with C++.
2507 Fixed problem with GNU readline detection on Redhat 7.0.
2509 Added step-size for Scan backend handler.
2511 Fixed bug that made the frontend server crash when no attribute
2512 set was specified for scan.
2514 Front-end server automatically switches to original working directory
2515 when installed as an NT service. Previously -w had to be specified to
2518 Added extended attributes for retrieval module (data1), so that data1
2519 records carry d1_readXML/SGML attributes. d1_read also supports
2520 null-data rules ( <tag/>)
2522 On UNIX when POSIX threads are available, a separate library libyazthread
2523 is created. Programmers should link with that library and the yaz library
2524 when using threads. The reason for the split was that some applications
2525 on Linux, such as Apache, doesn't work well when using shared objects that
2528 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2529 (or any frontend server) in SSL mode by specifying ssl: followed by
2530 address. Only tested on UNIX.
2532 Added feature for CCL module. Virtual structure s=al or s=ol generates
2533 and-list and or-list respectively instead of phrase search.
2537 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2538 log_mask_str. This was done to avoid name conflicts with other libraries
2539 (such as other PHP extensions).
2541 Added raw OID member for preferred record syntax (request_format_raw)
2542 and returned record syntax (output_format_raw) for backend fetch method.
2544 Config file yaz-config now accepts options so that it returns specific
2545 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2547 Shared library support for UNIX using GNU libtool.
2549 * Modified backend interface. Request/Response struct's replaced by
2550 one read/write C struct. For example bend_fetchrequest and
2551 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2552 Every handler - even search has to be registered in bend_init
2553 handler. This means that the YAZ library no longer refers to
2554 external functions and it makes it possible to make the whole
2555 thing a single DLL/SO.
2557 Added Segment handler for backend server.
2559 Added Zmbol/Zebra administrative functions to YAZ client.
2561 Threaded frontend server on UNIX (when POSIX Threads are available).
2562 Starting the server with option -T enables multi-threading.
2566 Added configure option --enable-comp/disable-comp to control use
2567 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2568 located in sub directory asn.
2570 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2571 in ${exec_prefix}/bin along with the other programs yaz-client and
2574 GNU automake used to maintain makefiles.
2576 Added several OID's.
2578 Changed retrieval module so that we can load records with no abstract
2579 syntax defined. Tagpaths in these records are fully composed of string
2582 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2586 On UNIX, the generated makefile now supports a proper 'make install'.
2587 The prefix can be set via GNU configure to set the install location
2588 (default is /usr/local).
2590 * YAZ programs client and ztest were renamed to yaz-client and
2591 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2592 locations, such as /usr/bin,/usr/local/bin,etc.
2594 * YAZ Header files were moved from include to include/yaz. YAZ Header
2595 files are referred to as include <yaz/log.h> rather than <log.h>.
2596 The YAZ include path (-I ..) is therefore the same as before. Programmers
2597 should update their #include statements or use -Ipath/include/yaz
2598 instead. The main motivation for doing this change is that YAZ header files
2599 can be installed in "standard" locations /usr/include,/usr/local/include
2600 without introducing conflicts, since ALL YAZ header files are stored
2601 in subdirectory yaz (under /usr/include for example).
2603 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2604 rather than project/workspace files. We switched because project files
2605 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2608 Changed name of logging function, logf, to yaz_log, to prevent name
2609 clash with some math-log functions. The YAZ header log.h defines logf
2610 to yaz_log (#define) so there should be no incompatibilities by this
2613 Added bend_start/bend_stop handlers for server. These handler are
2614 called on start/stop of server. For windows they are called whenever
2615 a service is started/stopped.
2617 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2618 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2619 in util/yc.tcl. The auto-generated C code structures are, in a few
2620 cases, incompatible with the old decoders. There are differences in the
2621 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2622 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2623 The preprocessor variable ASN_COMPILED is defined when the compiled
2624 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2625 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2626 wish to use the old encoders/decoders you can specify --disable-yc
2629 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2630 version so that it supports both new - and old version of DB Update
2632 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2633 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2634 change. The name parameter can be set to 0 in which no name is specified
2635 for the construction. The macros odr_implicit and odr_explicit sets name
2636 parameter to zero for the construction involved. New macros
2637 odr_implicit_tag and odr_explicit_tag are similar to the others,
2638 except that a name parameter is added. For programmers' that don't use
2639 ODR they probably only need to change the call to z_APDU and z_External.
2641 Added access control facility by interfacing the TCP wrapper library.
2642 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2643 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2644 name of the daemon and enables the access control as specified in
2645 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2647 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2648 den Dool <H.M.vdnDool@kub.nl>.
2650 Added reference ID parameter to most functions in server API - refer
2651 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2653 Changed name of ccl library to libccl.a (was ccl.a).
2655 Fixed bug in decoder for Explain (Category TargetInfo).
2657 Added support for GNU readline in client. Thanks to Jacob Poulsen
2658 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2660 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2661 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2662 IMPLEMENTATION! This change was made to the development version before
2663 the ZIG decided to retract the amendment. If any users MUST be
2664 compatible with the original Update definition, PLEASE CONTACT US, and
2665 we will include a separate definition corresponding to the old Update
2666 ES. Note that because of the change to the ASN.1 of the
2667 TaskPackageRecordStructure we cannot define a single structure that
2668 will support both versions.
2670 * Added const modifier to buffer parameter for some ODR/BER encoding
2671 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2672 completeWAIS, odr_dumpBER.
2674 Fixed bug in client.c which caused a crash when a scanResponse didn't
2675 contain positionOfTerm.
2677 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2678 * will cause an error in a client if a non-YAZ target sends both a
2679 * list of Scan entries and non-surrogate diagnostics.
2681 Retrieval module enhancements. Tag sets may be typed in the reference
2682 to it. From the .abs-file the "tagset" directive takes a third optional
2683 integer type for the tag set referenced. From a .tag-file the "include"
2684 directive takes a third optional type as well. The old "type" directive
2685 in the tag set itself is still recognized but acts as the default type
2688 Backend interface change. Individual Scan terms returned from bend_scan
2689 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2690 in include/backend.h.
2692 Retrieval module enhancements. Multiple tag sets and attribute sets may
2693 be specified in abstract syntax specs. Revised the error/warning for
2694 logging messages reported by the retrieval module when reading the
2697 Object Identifier system (oid_..) changed. The API is backwards
2698 compatible but the oid-routines now allocates new OID's when needed.
2699 Raw OID's may be specified in oid_getvalbyname.
2701 YAZ now uses GNU configure to generate Makefile(s).
2703 * Minor changes in some of the member names of DeleteResultSetRequest and
2704 DeleteResultSetResponse. See include/proto.h.
2706 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2707 and added member 'languages' in TargetInfo (which was missing).
2709 Changed the way attribute sets are handled in the retrieval
2710 module. These are now cached, just like the abstract syntaxes
2713 Changed YAZ so that it links with compiled ASN.1.
2715 Added Explain-schema definitions and mapping routines. The following
2716 Explain categories have been implemented: AttributeDetails,
2717 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2719 Fixed minor bug in Windows version of Server Library.
2721 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2723 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2725 Added EXTERNAL: UNIverse Resource Report (non-standard).
2727 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2728 ENUMERATED and SET OF.
2730 * Added 'const' to some of the char pointer arguments for the
2731 functions, data1_read_node, data1_getelementbytagname,
2732 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2735 Fixed bug in data1_insert_taggeddata - the last_child member of
2736 parent wasn't initialised.
2738 * Changed data1_read_record and data1_read_node so that the supplied
2739 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2740 doesn't refer to any parts of the "SGML"-buffer.
2742 Fixed bug in server library (Windows version of statserv_remove).
2744 * Changed code so that it compiles as C++. The type definition
2745 of Odr_fun which is a member of Odr_arm was changed. The result is,
2746 that an explicit typecast is needed for the fun pointer when
2747 using Odr_arm - as in:
2748 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2750 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2752 Implemented the new structured date and time definition as approved
2753 by the ZIG. Added schemaId element to the specificTag in Espec-1
2754 (also approved at the last ZIG). Thanks to RVDM.
2756 Added some Object identifiers (RVDM).
2758 Changed the Update Extended Service (RVDM).
2760 Added command "refid" to client which specifies referenceId for
2761 the following requests.
2763 Implemented extended service handling for server. See ztest.c
2764 for an example as well as backend.h. New handlers are registerd
2765 in the Init handler.
2767 * Changed interface for sort in server.
2769 Added new members to statserv_options_block. It allows a server
2770 to read options from another source than just the command line. Thanks
2771 to Charles Woodfield.
2773 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2774 renamed to zboolean. Some C++ compilers complained about the name.
2776 Minor changes to gils.abs. Added index 's' (sort) on title
2777 and date/time-last-modified.
2779 --- 1.4pl2 1998/1/30
2781 Fixed bug in server library regarding inetd mode (-i). This bug
2782 was introduced by release 1.4.
2784 --- 1.4pl1 1998/1/29
2786 Added sort facility in client and backend server interface.
2788 Fixed problem with dependencies in Makefile(s).
2790 Fixed bugs for encoders/decoders of extended services and
2793 Implemented sub-tree feature for schemas. Sub-trees are
2794 referenced in *.abs-files. See explain.abs for an example
2795 of the use of this feature.
2797 Modified bib1.att; local attributes for ANY didn't include
2798 ANY itself (only affects use of the retrieval module).
2800 Fixed bug in plain SGML reader in function data1_read_node:
2801 tags with prefix "var" was incorrectly interpreted as variants.
2803 Added feature "sub-schemas" to enable references to - and definitions
2804 of - group of elements.
2806 * Removed member parent from type data1_element (in data1.h).
2808 Implemented function odr_nullval() that returns the value of
2811 * Removed member num_children from data1_node (in data1.h).
2813 Made NT service interface part of the server library. The
2814 function statserv_main uses the NT service when required and
2815 calls the statserv_start / statserv_close routines.
2817 Routine zget_SearchRequest and zget_PresentRequest fills
2818 resultSetName/Id member with "default" instead of "Default".
2820 Fixed memory leak in server. Request queue member wasn't freed.
2822 Fixed nmem_exit so that memory is freed.
2826 Revised the CCL parser utility to be thread safe.
2828 Added function, oid_ent_to_oid, to replace the function
2829 oid_getoidbyent, which is not thread safe.
2831 * Added nmem_init and nmem_exit to initialize and release
2832 NMEM resources. Function nmem_init should be called once in the
2833 initial thread before NMEM/ODR is used. statserv.c and client.c
2834 have been changed accordingly. The change was necessary to make
2835 NMEM thread safe. The NMEM memory pool is shared amongst threads
2836 in a process. Unix-based applications will still work fine without
2839 Added NT Services interface for the the Z39.50 (statserv) Server.
2840 Refer to the ztest.c source on the usage.
2842 Windows 95/NT port using MSVC5.0. Project files are included in the
2845 * Defined new 'global' handle for the retrieval (data1) system. The
2846 new handled, data1_handle, describes the state of the data1 system.
2847 This handle is passed as first argument to virtually all
2848 data1 related routines. The functions data1_create and data1_destroy
2849 creates and destroys a data1 handle respectively.
2851 Added ODR encode stream member to all backend request structures
2852 init, search, scan etc. This stream should be used to allocate all
2853 memory used for the response when thread safe operation is needed.
2855 Changed the comstack utility, cs_addstr, to be thread safe. The
2856 returned hostname string returned by the function is now part the
2859 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2860 function. The cs_straddr takes a COMSTACK handle as argument, so this
2861 function must be used after cs_create and before bind/connect.
2862 This function is thread safe.
2864 Moved test server to 'ztest' directory - generic server code still
2865 in 'server' directory.
2867 Made prefix query (pquery.c) utility thread safe.
2869 Added new function modifier YAZ_EXPORT to 'export' public DLL
2870 functions when using windows (see include/yconfig.h).
2872 Added definitions to the OID database (util/oid.c) (RVDM).
2874 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2876 Added call to ccl_rpn_delete in client program.
2878 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2879 release of RPN structure.
2881 Added support for C++, headers uses extern "C" for public definitions.
2882 With input from RVDM.
2884 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2885 Thanks to Ronald van der Meer (RVDM).
2887 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2889 Added support for private extensions to the OID database
2890 (oid_setprivateoids()). Thanks to RVDM.
2892 Added optional, physical ANY (key replication)
2894 Fixed null-reference problem in GRS-1 output filter.
2896 Proximity operator added to Prefix Query Format (PQF).
2898 In test client command "base" accepts multiple databases.
2900 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2904 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2906 Smallish bug-fixes in the new encoders/decoders (explain).
2908 Bug fixed in DeleteRequest.
2910 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2912 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2914 Added SOIF syntax (using private OID for now) to retrieval module and client.
2916 Added Update extended service.
2918 Added SearchResult-1 additional info structure.
2920 Added optional CCL (ISO8777) interpreter as separate module. Available
2923 --- 1.2 1996/6/10 (1st anniversary release)
2925 Added Summary record syntax. Lightly tested.
2927 Added OPAC record syntax. Untested.
2929 Added ResourceReport service encoders/decoders. Untested.
2931 Fixed bug in z_Unit - wrong tagging on unitSystem.
2933 Fixed bug in the DiagRecs decoder.
2935 Added options for max PDU size and session timeout to frontend-server.
2937 Added documentation of query-language parsers and other supporting utilities.
2939 [frontend-server] Added Attribute set to the bend_scanrequest API.
2941 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2942 surrogate diagnostics were generated.
2944 [retrieval] Allow multiple local values for attribute.
2946 [retrieval] Allow multiple attributes per element in .abs files. index type.
2948 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2950 --- 1.1pl2 1996/4/10
2952 Minor changes, mostly specific to Zebra's requirements (retrieval)
2956 Repaired bug in frontend server when running multiple listening
2957 endpoints in dynamic mode.
2959 z_External() now won't break if a known, ASN.1 value comes encapsulated
2960 in an octet-string. The value will pass through unmodified in an Odr_oct.
2962 Added a bit of code to the demo client to decode & display
2963 ASN.1-structured records represented in the octet-aligned branch of
2964 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2966 Added z_ext_getentbyref() to the ASN module. Doc updated.
2968 * Completed the SCAN definition in the ASN module. This may break SCAN
2969 code based on older YAZ-versions at compile-time. The fix is easy -
2972 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2973 under the SCAN definition. Remember to initialize this, server-people.
2975 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2976 that this does not extend to ODR and ASN.
2978 Comstack allows insertion of established socket (primarily for
2979 inetd-operation of servers). Doc updated.
2981 Front-end server can now start from the inetd in TCP mode. Doc
2984 --- 1.0pl4 1996/1/24
2988 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2989 the rank and record number.
2991 Adjustments to the frontend server.
2993 Fixed diagnostic BER dumper. It ignored the file argument.
2997 Various changes to retrieval module.
2999 Changed the union discriminators of the protocol files from enums to
3000 ints paired with #defines.
3002 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3005 *Changed operator in the RPN structure to 'roperator', again to avoid a
3008 Fixed problems in Explain decoders/encoders.
3010 --- 1.0pl2 1995/12/6
3012 Memory bug in log module fixed.
3014 --- 1.0pl1 1995/12/5
3016 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3018 Bug in Explain DatabaseInfo module fixed.
3020 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3024 The shift to v1.0 signals that we now consider the *core* functionality
3025 of YAZ reasonably stable (the core being more or less equivalent to
3026 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3027 tested (Explain not at all - though that will happen soonish).
3029 Minor changes to code to support Windows port.
3031 Various minor changes after we're getting to use GRS-1 & co. more.
3033 Added Espec-1 format.
3035 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3036 of the protocol and it cannot be selected when encoding (maps into 'string'
3037 when decoding). Needed to talk to some servers.
3039 Demo client can request simple element set names.
3041 Added Diagnostic Format encoders/decoders.
3043 Added simple Close handling to frontend server (no hooks for resource
3044 reporting yet), and demonstration client.
3046 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3048 --- 1.0b3 1995/08/24
3050 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3051 handled incorrectly when records were requested in the searchResponse. This
3052 will only affect you if you use the frontend-server.
3054 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3055 Test-client will ask for and print GRS1. Ztest will return dummy records
3058 Added Explain encoders/decoders to the service-level API. Untested.
3060 Added Extended Services: Item Order encoders and decoders to the Service-
3061 level API. Untested. We could use a recent copy of the pertinent bits
3062 of the ILL protocol to add those bits.
3064 Added diagnostic format 1 encoders/decoders to the service-level API.
3067 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3068 odr_cons.c, which causes a more correct output.
3070 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3071 was always set to 0 when no records were requested in the searchRequest.
3073 * Added better external-handling. This shouldn't harm old code that
3074 *encodes* externals. It can break code that looks for a
3075 'single-ASN1-type' representation, since those types that are known
3076 are now decoded immediately. Look at the SUTRS sample code in
3077 seshigh.c and client.c. Documentation updated.
3079 Handling of structured records in bend_fetchresponse. Length -1 marks
3080 structured record, type is deduced from format field.
3082 --- 1.0b2 1995/06/27
3083 Fairly quick maintenance release to add SUTRS support.
3085 Fixed handling of SUTRS records in the demonstration client.
3087 * Added format field to the bend_fetchrequest and bend_fetchresponce
3088 structures of the backend API (frontend server). When the record is
3089 returned, the value of the format field is mapped to an OID. The
3090 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3091 of the record. The special value VAL_NONE in the bend_request means
3092 that no specific format was requested by the client. Documentation
3093 updated accordingly. Test server (ztest) will return a fixed dummy
3094 SUTRS record if your client requests SUTRS.
3096 Documentation updated accordingly.
3098 You can now set external libraries and RANLIB support in the top-level
3102 First public release.
