3 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
4 APDUs for a connection to a WRBUF.
8 Fix cql_sortby_to_sortkeys. Completely broken before.
10 Make CCL's @truncation work again.
14 New ZOOM connection setting: tproxy. It's like proxy, but does not
15 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
16 to set resolved address + port for a connection outside ZOOM itself.
18 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
22 Fix uninitialized variable in Solr spell support (could cause SEGV
23 for SRU response decoding).
25 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
26 back-end's addinfo through into the ZOOM response addinfo.
28 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
29 they are separated by a colon and a space rather than simply
34 Add support for Solr spell-checking/suggestions through ZOOM.
35 If a Solr target has been configured correctly for spelling-checking
36 and suggestions, these will now be returned on the ResultSet option
37 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
41 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
42 with a flag whether to substitute escape sequences or not.
46 Fix nmem_strsplit_escape to substitute escape char properly.
48 New option for zoomsh -e , which makes it abort on first error and
49 return process exit code to indicate success/failure.
51 YAZ options utility supports special option -- which makes all it treat
52 all following arguments as non-options.
56 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
57 searched if absolute filename is given.
59 Fix conv_xslt() error-reporting when stylesheet is not found.
60 (The value of fullpath is meaningless in this situation.)
64 Fix problem in CQL sort node creation: un-initialized memory.
66 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
67 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
68 CQL sortby depending on whether Type-1 or CQL is actually sent to the
71 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
72 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
74 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
75 will make it possible to use both single-character mask (#) and wildcard (?)
76 in CCL . Throw diagnostic for left truncation because that is not supported
81 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
82 cases using escapes (\-sequences) and masking.
84 PQF parse fix: A trailing backslash followed by end-of-string (\0)
85 would result in a read one byte beyond string.
87 rpn2ccl may use Z39.50 masking for terms (t=z).
89 ICU check fix. Don't include library -lCrun on Solaris, unless present.
91 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
92 not --cppflags (which seeems like an error in icu-config).
94 -- 4.2.12 2011/08/27 RPM package only
96 cql2ccl: fix conversion of terms: operator characters were not
99 -- 4.2.11 2011/08/25 RPM package only
101 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
102 CCL parser will map both # and ? to their regular expression
103 quivalents (. and .*).
105 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
106 of reserved CQL characters.
108 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
109 is, so that they are passed through.
113 ZOOM SRU mode: more aggressive re-connect.
115 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
116 made available as a utility function, declared in <yaz/logrpn.h>
118 rpn2cql_structure() supports proximity nodes (except that the Type-1
119 proximity node's "exclusion" binary is ignored, as there is no way to
120 express that in CQL). Fixes bug #4564.
124 Fix SEGV that could occur if set command of zoomsh was given without
125 value (2nd argument).
127 Fix SEGV that could occur if unsupported transport was given for
128 COMSTACK - say https (when SSL was unavailable).
130 Build yaz-url on Windows too.
134 New utility to get web content. Header is url.h. A command line tool
135 yaz-url is part of the distribution and packages.
137 Fixes for SSL COMSTACK (when gnutls is in use).
139 New functions yaz_base64{encode,decode}. Header is base64.h.
143 ZOOM C includes HTTP response buffer as additional info if it fails
144 to decode the SRU response.
146 Make wrbuf_json_puts available.
150 zoom: throw diagnostic for invalid value for option "sru". Before a
151 bad SRU request was sent.
153 Adding new utility wrbuf_vp_puts.
155 Add cclxmlconfig.obj to win/makefile. It was missing completely.
159 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
160 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
161 redirect was used at the same time.
163 MARC line mode decoding: be less picky about length given - first
164 5 digits of header that is.
166 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
168 Changes to decoding of SRU records: a record with recordPacking=xml is
169 modified with a new root element <yaz_record> if the recordData contains
170 multiple children elements. This is to make the record XML parseable
173 RPN to SOLR conversion: encode special characters.
175 Generic Frontend Server: fix uinitialized member, stepSize.
179 Fix a bug in SRU decoding of records.. The database records stored
180 had un-initialized memory, but it would only be seen with yaz_record_render
181 and type_spec="ext" .
183 Fix a bug in ccl_qual_dup introduced in 4.2.3.
187 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
191 Add new utilities to convert from CQL to CCL . These utilities have
192 prefix cql_to_ccl defined in cql.h.
194 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
195 lead to memory heap corruptions when ICU utilities were in use.
199 Make compilation work without Libxml2.
201 yaz-client: remove redundant blanks in display of searchResult-1 term
206 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
207 resulting CQL node (tree) in a new node CQL_NODE_SORT.
209 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
210 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
211 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
212 Note that the CQL sortby spec is only converted when the GFS is already
213 converting from CQL to RPN (cql2rpn element).
215 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
216 specify whether to collapse delimitors or not. The existing nmem_strsplit
217 do collapse (collapse parameter = 1).
219 Windows installer: For NSIS, set InstallDir depending on x86/x64.
221 Rename internal func yaz_use_attribute_create. While non-static, this
222 function is not declared in a public header.
226 Add -lCrun when linking with ICU on Solaris.
228 More quicks character set conversions for OPAC records.
232 fix problem with record_render: records were converted (character set
233 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
237 SRU: add methods for handling DADS SRU-proxy facets.
239 Separate OPAC record character set for ZOOM_record. yaz_record_render
240 allows a character set given as charset=from/opacfrom,to where 'from' is
241 the character set of a bibliographic record, 'opacfrom' is character set
242 of OPAC record and 'to' is the target character set.
246 yaz-client: show may XML format records. Command show followed by 'format'
247 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
250 src/stemmer.c: Avoid using unnamed union. It is not supported by some
253 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
256 Update yaz.spec to operate on both SLES11 / Centos 5.5.
258 RPM: Release includes 'indexdata' name. Use indexdata in release name so
259 this package can be distinguished from other vendors.
261 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
262 as determined by configure
264 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
266 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
267 returns no error and no record, the present request is considered
268 partial (only a subset of the records could be returned by backend), and
269 so it is appropriate to set Present Status to partial-4.
273 Move yaz-config man pages to section 1.
275 More documentation about SOLR.
277 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
278 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
279 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
280 peers on some Linux systems. However, in general that does not work
281 so YAZ can not rely on that to work. Debian changed behavior in this
282 respect from Debian lenny to Debian squeeze (still testing as of Oct
284 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
286 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
290 Fix yaz-config output: echo_source not set correctly by configure.
294 SOLR WebService support for yaz-client and ZOOM.
296 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
298 --- 4.0.12 2010/08/17
300 Z39.50 facet support. Facet specifications are passed for search in
301 other-information with ASN.1 as defined in facet.asn and OID
302 .10.1000.81.5 . Facets are expressed as an Attribute list as known
303 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
304 3 is limit (number of entries to get in response). yaz-ztest returns
305 dummy facets if a client asks for them.
307 --- 4.0.11 2010/07/09
309 CCL fixes: bug 2895 and bug 3539.
311 GR1-display: add comma in display - was removed by mistake in
314 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
316 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
318 --- 4.0.10 2010/06/18
320 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
321 result set from a connection. The result set will be on its own
322 thereafter; no operations on it will perform retrievals from a target.
323 Only cached copies are returned.
325 ZOOM C:fix case for HTTP servers responding with Connection:close.
326 Ensure that if there is a current task it is resumed (like fetching
327 more records in a result set) . Bug #3484.
329 PQF parser: use odr_atoi for Odr_int (not atoi)
331 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
332 values that contain any non-digits are treated as string attributes
333 (previously decoding only checked for leading character ([0-9]). PQF
334 encoding: attribute string values are not surrounded by double-quotes.
338 New utility for managing threads - thread_create.h.
340 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
341 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
342 but YAZ' implementation do.
344 Fixes for yaz_cond-functions on Windows 7.
346 DLL export more symbols.
348 zoomsh: show record do NOT render opac.
350 Remove *.la files from Debian and RPM packages.
354 Debian package libyaz-dev depends on libgnutls-dev again (was
355 removed in YAZ 4.0.6, but due to Libtool it is still needed
356 even though yaz-config do not list libgnutls libs).
358 ZOOM: Use only one WRBUF for returning string results for
359 ZOOM_resultset. Reduces memory usage for ZOOM in general.
361 ZOOM: ZOOM_connection do not use a shared pointer to
362 ZOOM_resultset after ZOOM_resultset is destructed by
363 user. Reverts to YAZ 4.0.4 behavior.
367 record-conv: fix problem with at least one XSL conversion -
368 due to probably incorrect usage of XML XSL documents.
372 Fix yaz-config for static mode and the use of SSL (gnutls).
376 Forward decl timeval struct in mutex.h and gettimeofday.h.
378 yaz-config: fix 'static' mode linking.
382 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
383 are wrappers for pthreads or Windows. For Windows these are put in
384 a separate DLL: yaz_cond4.
386 libyaz.la (whole source) is compiled with thread. If thread support
387 is enabled enabled, all source of YAZ is compiled with treading support.
388 This allows core utilities such as yaz_log to use thread facilities.
389 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
390 thread utilities. This commit moves mutex utilities (mutex.c) from
391 libyaz_server.la to libyaz.la.
393 yaz-json-parse displays leading text until error.
397 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
398 patch from Giannis Kosmas.
400 SRU: no longer URL encode SRU database. The URL for an SRU server is
401 a URL and such is alreeady encoded - at least when given with leading
402 http:// or https://. This reverts behavior to YAZ 3.0.50.
404 Support for new MARC XML notation TurboMARC which like MARCXML is a
405 complete representation of MARC/ISO2709.. This one, however, is more
406 compact and allows for faster processing with XSLT. TurboMARC can be
407 used in the marcdisp.h API, from the yaz-marcdump utility and from
410 yaz-ztest can be configured - via the database - to perform certain
411 delays when it performs operations search, present and single record
412 fetch. This allows testers to make yaz-ztest act as a real or even slow
413 Z39.50 server. Refer to the yaz-ztest man pages for details.
417 wrbuf_destroy allows NULL WRBUF passed to it.
419 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
421 Add ZOOM_connection_close.
423 No fixed size buffers for ZOOM shell - bug #3257.
425 tstodr: make it work on s390 platform.
427 New icu iterator-functions. The new icu_iter-functions makes it possible
428 to use ICU chains from many threads.
430 yaz-client: better syntax check for show command.
434 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
437 New simple local-file XML include facility which allows file glob-patterns.
438 Refer to yaz/xml_include.h.
440 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
443 ZOOM_record_get supports new parameter "format" which makes it format XML
446 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
447 JSONText in ECMA-262) is JSONValue, not JSONObject.
451 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
452 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
454 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
455 POSIX/Unix builds .so with major version 4.
457 Remove old LOG_-defines from log.h. They have been obsolete and
458 undefined by default for the last 5 years.
460 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
462 GFS: Remove socket (int *fd) from search_rr handler. The socket
463 descriptor ptr is a facility that allowed a search handler to supply
464 a socket which would serve as a callback - when search was complete.
465 This facility has now been in use for years.
467 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
468 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
469 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
470 returns 'const char *' rather than 'char *. The returned string is
471 read-only and should not be modified by applications. COMSTACK cs_close is
472 now a void function - it no longer returns int. No applications check for
473 the value and the implementations has always returned 0.
475 ZOOM: use size_t for scan hit counts and str size. Functions
476 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
477 occ (hit count) and len (string length) are now of type size_t pointer
478 rather than int pointer. This is to be able to represent large hit counts
479 and to also just to use the proper type for string length (strlen result).
481 New JSON parser. Refer to include/yaz/json.h .
483 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
484 Used to be int in some cases. Many wrbuf_-functions used to return an int
485 indicating some length.. These return values were never used. And so they
488 ODR: odr_malloc, odr_total now takes size_t for size.
490 clone_z_type: fix leak; occurred for encoding failures.
492 --- 3.0.52 2009/12/03
494 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
495 bug was introduced in 3.0.51.
497 --- 3.0.51 2009/12/02
499 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
501 tcpip comstack: fix leak for getaddrinfo.
503 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
504 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
505 Decoding of SRU "path" database is performed by private function
506 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
507 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
509 yaz-client: honor base command for SRU. Change when database setting
510 is applied for SRU and ensure it is kept when a connection is reset.
511 Change also the way errors are displayed or SRU (decoding of packages).
513 --- 3.0.50 2009/11/02
515 Add support for extra request / response data for SRU codecs and GFS.
516 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
517 for extra data response buffer and length. For the GFS, both request
518 and response data (XML) is carried in extra_args and extra_response_data
519 for the search handler. Patch by Ko van der Sloot.
521 ZOOM: For queries that cannot be converted to the specified rpnCharset,
522 ZOOM now returns a diagnostic on the client-side ('invalid query' /
523 10010). This fixes bug #2113.
525 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
526 cmdfile included a 'quit' command that would result in a memory violation.
528 --- 3.0.49 2009/10/01
530 Make a number of functions defined in xmlquery.c static. These have
531 never been declared in a public header file (yaz/xmlquery.h) and was
532 made public by mistake.
534 Improve speed of character conversions (iconv utilities). This makes
535 conversions from MARC-8 faster.
537 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
538 unless type desired is "raw". This will prevent type "xml" from
539 returning ISO2709 .. Which obviously can not be XML parsed.
541 Fix memory leak in ZOOM that would occur if option apdulog was used
542 on a re-used connection.
544 Frontend server logs HTTP requests.
546 Frontend server now sends Z39.50 close when it times out (sesssion has
547 been idle for too long). Versions 2.0.30 and earlier also sent close.
548 But due to a mistake this was disabled in all versions after that, i.e.
549 the server would just close the socket immediately.
551 yaz-client emits a better message when receiving an unrecognised
552 userInformationField.
554 Skip zero-length subfields when decoding ISO2709. This rare case happens
555 if a record has two FS characters in a sequence. Without this patch
556 there would be a reference beyond char array in using_code_len fragments
559 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
561 --- 3.0.48 2009/08/28
563 The show command offered by the zoomsh command now takes a 3d optional
564 parameter type which is what is passed to ZOOM_record. If the type
565 argument is omitted, "render" is used.
567 RPN to CQL conv may use USE string attributes (bug #2978).
569 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
571 --- 3.0.47 2009/07/08
573 Function yaz_xml2query allows a diagnostic element in the PQF XML
574 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
575 code and additional info respectively.
577 The BER BOOLEAN is now the integral type Odr_bool which still happens
578 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
579 typedef'd to Odr_int. This is still an integral 'int', but it may be
580 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
581 ASN-1 compiler as well as programs has been updated to use the new types.
583 --- 3.0.46 2009/06/08
585 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
586 only the bibliographic record was rendered. For type=opac, an OPAC
587 record is only returned if it is present.
589 iconv: small fix for encoding of advancegreek.
591 yaz-client: avoid double display of SRU/SRW records (bug #2798).
593 yaz-client: option auto_reconnect=on really reconnects.
595 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
597 server: avoid null ptr ref for for yaz_poll errors.
599 build: fix RPM build for RHEL 5.3.
601 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
603 --- 3.0.45 2009/03/31
605 Fixed bug #2709: TCP connect returns Invalid argument.
607 Fixed compilation for mingw.
609 Honor charset for raw records (ZOOM_record_get).
611 Fixed use of errno for threaded mode that was seen on Solaris 10.
613 Fixed argument passing with blanks in value for Windows Service.
615 Disable YAZ' own log rotate by default (no 1 GB limit).
616 The variable l_max_size which specifies the log file limit is set to 0
617 (DISABLED): This is due to the fact that YAZ is most often deployed using
618 logrotate. Also YAZ can not perform log rotate because of unsufficient
619 permissions (setuid).
621 --- 3.0.44 2009/02/17
623 List supported encodings in man page for yaz-iconv.
625 Fixed missing SSL libs for --libs output
627 Re-established OID record syntax application-xml. Nobody should use it
628 but we don't want to change soname because of this symbol being absent.
630 --- 3.0.42 2009/02/02
632 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
634 Added member named_result_sets for init handler struct for the GFS. This
635 allows a server to disable named result sets.
637 Removed OID record syntax application-xml.
639 Added support for rule-based transliterator for ICU wrapper of YAZ.
641 Fixed bug #1902: yaz-icu XML output.
643 Make YAZ checks Emacs friendly.
645 BITSTRING value shows value. Bug #2346.
647 ISO2709 decoding: skip control characters from indicator data.
649 Omit sort key by default in yaz-icu's output.
651 Allow combined single char options (again) for YAZ' options function.
653 Utility yaz-marcdump got option to display YAZ version (-V).
655 Allow YAZ to use ICU 3.4.
657 Added new ICU test case which illustrates removal of diacritics.
659 --- 3.0.41 2008/12/29
661 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
663 --- 3.0.40 2008/12/29
665 For configure, using option --without-xml2 also disables Libxslt/Libexslt
668 Fixed bug #2352: yaz-marcdump crashes for certain record.
670 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
672 Added support for Danmarc2 to UTF-8 conversion.
674 Added support for ISO5426 to UTF-8 conversion.
676 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
677 implementation version.
679 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
681 --- 3.0.38 2008/11/10
683 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
684 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
686 ZOOM C now interprets databaseName option for ZOOM connection as path
689 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
691 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
693 Dummy Libxml2 types no longer defined in headers of YAZ'.
695 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
698 --- 3.0.36 2008/09/26
700 Various ODR chapter fixes.
702 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
704 Added missing source for Windows compilation, mutex.c.
706 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
708 For SRU connections in ZOOM all records up to "count" are now fetched.
710 Fixed crash in generic frontend server (and yaz-ztest) which occurred
711 in Windows due to bad error handling for Libxml2.
713 Added facility for sending arbitrary records (ASN.1 any) using
714 ZOOM C's Extended service update. Patch by Sam Reynolds.
716 New options for ZOOM C's connection, logapdu which makes ZOOM log
719 --- 3.0.34 2008/06/18
721 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
723 --- 3.0.32 2008/06/12
725 Fixed memory violation that could occur when decoding UTF-8. This bug
726 was only present in 3.0.30 of YAZ.
728 --- 3.0.30 2008/06/06
730 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
731 GNU TLS is used by default (if found).
733 yaz-ztest returns OPAC records if a client asks for OPAC.
735 Improved speed of MARC-8 encoding.
737 Added support for lossy and loss-less MARC-8 encoding.
739 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
741 Added new Windows Service wrapper (sc).
743 yaz-client's itemorder command may now send a file.
745 Fixed yaz-marcdump to allow the use of NS prefix for record element.
747 Added new function yaz_log_xml_errors.
749 Allow (but warn) unknown XML attributes in MARCXML parsing.
751 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
753 The UTF-8 to MARC-8 conversion now uses a different set of characters
754 for Greek symbols. Bug #2120.
756 --- 3.0.26 2008/02/21
758 Added yaz_daemon (daemon.h).
760 Fixed bug #2068: pkg-config trouble
762 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
764 --- 3.0.24 2008/01/28
766 Document --with-xml2 option.
768 Added OPAC XML XSD (etc/opacxml.xsd).
770 Allow glob mask for name attribute in retrieval element for the
771 generic frontend server's retrieval facility.
773 Changed yaz_poll_poll to return yaz_poll_except for all returned events
774 except POLLIN/POLLOUT.
776 Fixed error handling in cs_listen. Bug #2037.
778 --- 3.0.22 2008/01/20
780 Fixed version in yaz/yaz-version.h.
782 Fixed bug #2027: Crash when closing connection.
784 Changed configure so that ICU support is only enabled if only ICU
785 and Libxml2 is available (because the ICU chain is XML based).
787 --- 3.0.20 2008/01/15
789 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
790 is built. Only this DLL depends on the ICU runtime.
792 yaz-ziffy is no longer part of YAZ. It is distributed separately by
793 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
795 Changed license of CCL module to 'Revised BSD'. After consultation with
796 remaining members of the original EUROPAGATE consortium, we are re-issuing
797 the CCL module without a separate license. The software was developed by
798 Index Data as part of a research project. The special license was included
799 to help feed usage information back to the project consortium to support
800 project evaluation. At this time, the project consortium has long-since
801 disbanded, and the majority of the original principals have retired. At the
802 same time, we have significantly modified the software during the following
803 years, to the point where very practically no original code remains. To
804 simplify re-use of the software, we have contacted those members of the
805 consortium who could be reached, and agreed to re-issue the module as a
806 proper part of the YAZ package.
808 Tcl scripts uses /usr/bin/tclsh as preferred shell.
810 CQL closer to being version 1.2 compliant. CQL also allows free-form
811 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
814 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
815 bug could make Extended services handling crash in the ZOOM layer. This
816 bug was only present in YAZ 3.0.18.
818 --- 3.0.18 2007/12/19
820 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
823 yaz-marcdump reads and writes collection wrapped records.
825 Handle OPAC for record conversion module.
827 Fixes for ICU wrapper.
829 Allow ICU libs to be controlled with --with-icu .
831 --- 3.0.16 2007/11/12
833 Added yaz_poll which is a wrapper for select/poll. When poll is available
834 and non-buggy, it is used, by yaz_poll . This allows more than 1024
835 sockets to be in use.
837 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
838 functionality through an XML based configuration (ICU chain). This system
839 is useful for search facilities such as Pazpar2 and Zebra that needs to
840 perform tokenization of indexed material. The ICU code in a separate
841 library libyaz3_icu.a.
843 Added HTTP tunnel facility for COMSTACK, bug #1752.
844 This is a facility that allows a Web proxy, such as squid, to tunnel
845 Z39.50 traffic. This facility is "transparent" to must applications
846 using YAZ. It's enabled by using pseudo transport connect: followed by
847 the proxy address, followed by command, then follwed by he regular
848 "virtual" addresss. For example,
849 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
851 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
853 --- 3.0.14 2007/09/21
855 Fixed bad memory reference in ZOOM_record - cuased by member not being
856 initialized. This was a problem only in YAZ 3.0.12.
858 Fixed bug in conversion from MARC to XML: Non-XML characters in control
859 fields were not removed.
861 Changed the way C code is generated from codetables.xml. Made a MARC-8
862 conversion trie for each characterSet section rather than codeTable.
863 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
864 of codetables.xml from Larry Dixson, LOC. Bug #1464.
866 --- 3.0.12 2007/09/12
868 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
869 from ZOOM_record_error).
871 ZOOM C function ZOOM_record_get returns record schema for type="schema".
873 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
875 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
877 Better SRW-to-Bib-1 diagnostic mapping.
879 ZOOM C and yaz-client announces SRU version 1.2 by default.
881 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
884 Fixed in yaz_sru_decode to allow other version than 1.1.
886 --- 3.0.10 2007/08/22
888 Added support for SRU scan for ZOOM.
890 Added support for the use of the older versions or Extended Service
891 Update in ZOOM. To faciliate this, an option "updateVersion" may be
892 set to the version , 1=first, 2=second, 3=third. The third version is
893 what ZOOM C has used so far. And that, obviously, is the default.
895 Added support for CCL queries in Z39.50 queries sent to the GFS (and
896 therefore in Zebra and in SimpleServer-based applications). The new
897 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
898 qualifier file used to transform incoming CCL queries into Type-1 RPN,
899 which is passed into the back-end search callback function.
901 Added support for HTTP Basic authentication in clients: the SRU/W
902 codec encodes the username/password elements of the PDU structure
903 appropriately, and these may be set using the "user" and "password"
904 options in ZOOM-C applications (the same options that are used for
905 Z39.50 authentication).
909 Fixed bug #1208: SSL appears to be broken in ZOOM.
911 Fixed bug #1206: Libxml2 include path weirdness.
913 Added oid_name_to_dotstring.
915 Allow elementSetName to be specified for ZOOM C record update.
917 Allow waitAction to be specified for ZOOM C based for Extended Services.
919 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
920 syntax OID. Bug introduced in YAZ 3 series.
922 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
926 Fixed bug #1157: yaz-client does not read .yazclientrc from current
927 directory. yaz-client now reads commands from file given by option -f
928 if specified; then tries to read .yazclientrc in current directory.
929 Failing that, it reads .yazclientrc from user's home directory.
931 Added support for correlationInfo Note and ID for Record Update via
934 Added yaz-client command querycharset which specifies character set for
935 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
936 (termListAndStartPoint).
938 Charset ISO5428:1984 is an alias for ISO5428-1984.
940 Implemented a way to perform scan in a result set using Z39.50. This
941 is achieved by attaching the result set name in the characterInfo
942 (type InternationalString) of OtherInformation in the Scan Request PDU.
943 The result set is identified in the otherinformation by the new OID:
944 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
945 This allows for scan in result set and faceted search . Zebra did some
946 of this in the APT term using attribute type 8 and value being result
947 set. Using the OtherInformation approach for this is cleaner and easier
948 to work with in proxies and the like. This facility can be used in
949 yaz-client using new command setscan which takes a result set as first
950 argument, start position (APT) as second.
952 Changed decoding of SRU XML packed records to deal with servers that
953 have recordData with XML data with multiple root nodes. Also make
954 comparison for recordPacking case insensitive. Again, one server
955 returns "XML" where others return "xml".
957 For SRU responses allow Content-Type application/xml as well as text/xml.
961 Fixed bug in character set conversion of BER strings. Bug introduced
966 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
968 For OID class, use oid_class consistently.
970 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
973 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
974 character set for bibliographic information interchange". By Giannis Kosmas.
976 Added documentation on new OID API.
980 Changes to generic frontend server interface: added new member
981 'query_charset' for bend_initrequest structure. A backend init handler
982 should set this member to its native character set for query terms.
983 When defined, the frontend server logic will announce this character set
984 to a client if the negotiationModel bit is set by the client. All server
985 implementors are encouraged to specify this. If a backend server does not
986 specify this a warning is issued using yaz_log(YLOG_WARN,..).
988 Added CCL utility to remove terms (stop words) from resulting RPN
989 tree. This is handled by functions with prefix ccl_stop_words_ .
991 New ZOOM C option, "rpnCharset", which allows client-side conversion of
992 terms in RPN queries.
994 Clean-up the CCL API. Moved some internal structures from ccl.h to
995 private header cclp.h. Changed ccl_parser_create so that a Bibset must
996 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
997 This is replaced by ccl_parser_find_str which takes a string instead.
999 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1000 libyaz.la is the core of YAZ except the generic frontend server and
1001 does not depend on POSIX threads anymore. libyaz_server.la is the
1002 generic frontend server facilities and uses POSIX thread functionality
1003 if available. The libyaz.la no longer depends on POSIX threads because
1004 the number of global structures is limited. NMEM no longer re-uses blocks
1005 between threads ; it simply free's memory immediately but allocates in
1006 "large" chunks as usual. We don't expect any performance penalties
1007 because of this. The yaz_log system is still using a global log_level so
1008 caution must be taken when modifying it with yaz_log_init_.. +
1009 yaz_log_mask_str. This, however, should not cause any trouble because
1010 these functions are called during initialization of application code
1011 anyway. `yaz-config --libs server` returns libs for server applications;
1012 `yaz-config --libs` returns libs for non-server applications.
1014 New OID database - with public definitions in oid_db.h. Removed old OID
1015 database including the head oid.h and definitions such as enum oid_value
1016 and struct oident. The new OID database uses the same string names as
1017 before but the 'protocol' is gone. There are now only two representations
1018 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1019 converts from string to OID; functions with prefix yaz_oid_to_string
1020 converts the other way.
1022 Change to emit_term() in CQL-to-PQF query translation: when a term has
1023 the /regexp relation modifier, do not process it for leading and
1024 trailing "^" and "*", which have quite different meanings in regular
1027 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1028 write handlers no longer carries a 'last' parameter. This will make
1029 yaz_iconv flush "less" characters. A flush is performed by call to
1030 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1032 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1033 removed, because function yaz_query_to_wrbuf does the same.
1035 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1036 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1038 Deprecated MARC utility functions removed.
1040 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1043 Branch split: YAZ_2_1_55_branch
1045 --- 2.1.54 2007/03/16
1047 Fix to ZOOM-C so that transparent reconnection is properly handled on
1048 connections that are in asynchronous mode.
1050 Fixed compilation on OpenBSD 4.0.
1052 Large strings in GRS-1 records are now properly displayed in yaz-client.
1054 Added character conversion support for "advancegreek"; based on patch from
1057 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1058 sequence is met. Before the error was not set so it would be unknown.
1060 Adjust yaz-marcdump MARC reader so that it skips until record separator
1063 --- 2.1.52 2007/03/07
1065 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1066 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1067 fd_set structure used as a bitmask for the FDs to be selected on.
1069 Using ACX_PTHREAD macro to check for POSIX threads.
1071 Fixed have-vsnprintf check.
1073 --- 2.1.50 2007/02/23
1075 Fixes for configure on BSD. Bug #900.
1077 Added snprintf/vsnprintf wrappers for systems that don't have
1078 limits (heavens forbid).
1080 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1081 created before all previous tasks were completed and removed from the
1082 task queue, the new task could be removed by a mistake.
1084 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1086 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1088 Fixed bug #832: Problem with MARC/charset in yaz-client.
1090 Fixed bug #668: save command line history for yaz-client.
1092 Fixed bug #830: pkg-config support.
1094 --- 2.1.48 2007/01/23
1096 Extended ZOOM result set options with two options that may be read by
1097 a client: resultSetStatus and presentStatus with values as specified for
1099 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1101 Fixed bug #827: Using SSL fails on Debian etch.
1103 Fixed bug #826: Weird looking chars for set of MARC records.
1105 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1106 that is treated as an ItemOrder with itemRequest being an XML document
1107 external. The value of "doc" is the content.
1109 Extended the GFS search facility. New member of bend_search_rr
1110 'estimated_hit_count' signals that hits is known to be an estmate
1111 (higher or lower than real hit count). New member 'partial_resultset'
1112 signals that the search was partial (hit count is lower or equal than
1113 real hit count). For Z39.50, the information is stored in resultSetStatus
1114 member of SearchResponse APDU. For SRU, the information is signalled
1115 via SRU diagnostic 59: "Result set created with valid partial results
1118 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1120 --- 2.1.46 2007/01/13
1122 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1124 Added ZOOM_connection_peek_event.
1126 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1127 the following new functions:
1128 ZOOM_event_nonblock, ZOOM_connection_process,
1129 ZOOM_connection_get_{socket,mask,timeout},
1130 ZOOM_connection_fire_event_{timeout,socket}.
1131 The existing blocking event handler, ZOOM_event, is a wrapper for the
1132 + blocking ZOOM_event_sys_{poll,select}.
1134 Implemented function ccl_xml_config which parses XML version of CCL
1135 configuration (bug #798).
1137 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1139 Added timings utility (yaz/timing.h)
1141 --- 2.1.44 2007/01/03
1143 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1146 Fixed bug #779: Rotation of apdu.log fails.
1148 Fixed for character set conversions:
1149 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1150 Honor G1 set in MARC-8 decoding.
1152 --- 2.1.42 2006/12/17
1154 Fixed bug #775: char conversion does not handle Alternative UTF-8
1157 Implemented function yaz_marc_read_line which parses MARC line format
1158 records. There is a wealth of formats out there. So far, this function
1159 reads line records produced by yaz_marc_write_line.
1161 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1162 more generic and easier to remember(!) options: -i format and -o format
1163 which specifies input format and output format respectively - where
1164 format is one of "marc", "marcxml", "line", "marcxchange".
1166 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1167 does not print anything except warnings for records.
1169 For yaz-marcdump, added support for MARC split into files (-s) with a given
1172 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1173 spec, at http://www.loc.gov/standards/sru/record-update/
1174 This has changed the binary layout of the following structs:
1175 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1176 bend_update_rr . Patch by Ko van der Sloot.
1178 Added GFS utility function bend_assoc_is_alive which returns 1 if
1179 association is still alive (client is connected); 0 otherwise (client
1180 closed connection). This allows busy servers to stop working for
1183 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1184 been a separate piece of software. This version of ziffy has been modified
1185 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1187 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1189 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1190 Client code may now interrogate options such as "init_opt_sort" to
1191 find out whether the server claims to support various options.
1193 --- 2.1.40 2006/11/27
1195 Added utilities yaz_{set,get}_esn to set/get element set name from
1198 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1199 of YAZ and has been so since YAZ 2.1.10.
1201 Implemented ZOOM_record_error which returns error information for
1202 record (surrogate diagnostic).
1204 --- 2.1.38 2006/10/31
1206 Updates for SRU Update by Ko van der Sloot:
1207 1. Changed name from "operation" to "action"
1208 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1209 versions in the code, marked as 'backward compatible'.
1210 3. Added diagnostics for SRU Update.
1212 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1214 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1216 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1218 For GFS, fixed problem with SRU diagnostic 'First record position out of
1219 range' being issued for 0 hits.
1221 zoomtst10 part of Windows Build.
1223 --- 2.1.36 2006/10/13
1225 Implemented yaz_filepath_comp which splits a path into file path
1226 components (required by Zebra 2.0.3+).
1228 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1229 BSD inspired license until now so this should not have any real impact on
1230 anybody. See http://www.opensource.org/licenses/bsd-license.php
1232 Fixed bug #687: Missing log lines.
1234 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1237 Fixed bug #689: SRU diagnostics to be added.
1239 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1240 whether a connection is idle (no more work do do).
1242 --- 2.1.34 2006/10/04
1244 Change type of optval from long to int for invocation of setsockopt with
1245 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1247 Added support for specifying the max log file size for the Generic
1248 Frontend Server. The size is given with option -r.
1250 --- 2.1.32 2006/09/21
1252 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1254 --- 2.1.30 2006/09/17
1256 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1259 Fixed bug in Generic Frontend Server that could cause a server to stop
1260 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1262 For the generic frontend server, the maximum record size is used as maximum
1263 size of incoming packages (SRU + Z39.50). The value until was previously
1264 only used in Z39.50 Init negotiation and, later, in a session controlled
1265 sizes of records returned. This is controlled using -k option. It can be
1266 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1268 --- 2.1.28 2006/09/04
1270 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1273 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1275 New option for yaz-marcdump -lpos=value which allows setting a portion
1276 of MARC header to a certain value.
1278 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1280 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1281 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1283 --- 2.1.26 2006/08/15
1285 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1288 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1290 --- 2.1.24 2006/08/08
1292 Fixed MARC ISO2709 encoding routines to deal with character set
1295 Minor changes to GFS logging. Database included in search request log
1298 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1299 cached/multiple records.
1301 Shared libraries are built by default on Unix+configure.
1303 Changed cql2pqf transformation to use a different evaluation order. The
1304 new order is: always, relation, structure, position, truncation, index
1305 and relationModifier. Old order was: always, relation, relationModifier,
1306 structure, index, position, truncation. Note that the the latter ones
1307 override former ones for identical attributes.. The new scheme means that
1308 it is possible to override any existing attribute with a relationModifier.
1309 And also that it is possible to override everything for the index rule
1310 (except the ones listed in relationModifier). No order is perfect but this
1311 one, we believe, covers more real cases.. The "always" should have been
1312 called "default", since the attributes there can be overridden with all
1315 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1316 compilation phase, but also for yaz-config --cflags output. This allows
1317 us to have public headers with Libxml2 stuff in them . It should also,
1318 eventually, make Libxml2 checks redundant in packages using YAZ, such
1321 --- 2.1.22 2006/06/15
1323 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1324 stored in uri, message and details.. Previously diagnostics were stored
1325 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1326 compatibility.. but he's probably the only one affected, so.
1328 Added support for CCL, compiled on the client side, in ZOOM-C. This
1329 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1330 input; the resulting query objects can be used for for searching with
1331 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1333 YAZ' configure searches for OpenSSL by default.
1335 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1336 SL_CTX_use_certificate_file. See
1337 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1338 for more info. Thanks to Ko van der Sloot.
1340 --- 2.1.20 2006/06/02
1342 Bug #600: SRU GET, POST support for yaz-client. Introduced
1343 command 'sru' which selects method SOAP/GET/POST.
1345 Allow missingValueAction to be specified for the sortspec string -
1346 function yaz_sort_spec. By default, the missing value action is null.
1347 Use ! to specify "abort". Use = followed by stringvalue to specify default
1350 Ensured that Present-handler (if defined) is called in GFS before any call to
1351 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1352 searchRetrieve requests.
1354 Documentation for YAZ is now based on the Docbook XML/XSLT using
1355 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1356 is no longer depending on jade/openjade or docbook-to-man scripts.
1357 PDF is no longer part of the distribution - but can optionally be
1358 made using DSSSL/jadetex or FOP.
1360 Added retrieval handling support in Generic Frontend Server to support
1361 conversion between MARC/XML as well as XSLTtransforms. See
1362 etc/yazgfs.xml for an example.
1364 Added Authentication support to Generic Frontend Server in SRU
1365 mode. Authentication using HTTP Basic is supported, as is the use
1366 of 'x-username' and 'x-password' parameters in the request itself.
1368 Added support for a new character set MARC8s identical to MARC8 except
1369 that it converts combined characters to single Unicode characters in the
1370 Latin-1 range (when possible).
1372 --- 2.1.18 2006/04/24
1374 ASN.1 compiler 0.4: generates brief Doxygen file header for
1375 generated .h/.c files.
1377 Utility yaz_iconv now supports conversion to MARC-8.
1379 New facilities for the MARC module. The reading - and writing of
1380 content are separate methods for the yaz_marc_t handle. The following
1381 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1382 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1383 format). Write functions have prefix yaz_marc_write_.. The existing
1384 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1385 available. Removed support for OAI-MARC and simplexml (not the
1386 simplexml from PHP5).
1388 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1389 to be returned for this connection.
1391 --- 2.1.16 2006/03/31
1393 Allow multiple languages and charsets to be specified with
1394 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1395 negcharset iso-8859-1,utf-8
1397 Translation of proximity nodes from CQL into PQF now works.
1399 Moved to automake 1.8, 1.9.
1401 Added function yaz_log_set_handler which allows a log handler to be
1402 installed. This handler will be called for all log messages. Output
1403 to file is also produced; but that can be disabled by passing NULL
1404 fname to yaz_log_init_file.
1406 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1408 For SRW (including GFS), accept application/soap+xml as content-type
1411 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1412 produces NO stylesheet reference even if a default stylesheet is specified
1415 --- 2.1.14 2006/03/14
1417 Updated Windows package to include yazd.dll + yazd.lib for the
1418 Development component.
1420 If the environment variable YAZ_LOG is set, then it is used as a
1421 string indicating the default level of logging to use if not
1422 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1423 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1424 used as before. So, for example, to omit warnings from YAZ logging,
1425 export YAZ_LOG=-warn
1427 cql_transform() now map structure and other attributes before indexes,
1428 so that index-specific structures and other attributes can override
1429 defaults. So now a combination of mapping specifications such as:
1431 index.dc.date = 1=date-modified 4=5
1432 does the right thing.
1434 cql_transform() now also respects the "always" mapping specification,
1435 which establishes an initial set of attributes to be used for all
1436 terms except where overridden by more specific attributes associated
1437 with the index, relation or modifier.
1439 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1440 which mode to use; one of "post", "get" or "soap" (SRW, default).
1442 Fixes for yaz_iconv routines: changed trie-based character set conversions
1443 to use only non-negative values for bit fields due to Sun's C compiler not
1444 supporting negative values.
1446 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1447 sequences where not read correctly. Fix by Rustam Usmanov.
1449 Updated win/makefile to use options, settings which makes things
1450 compile with VS C 2005.
1452 --- 2.1.12 2006/02/01
1454 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1456 In ZOOM socket code, use select instead of poll on MacOSX.
1458 ZOOM-C now support client-side compilation of CQL into RPN that is
1459 sent to the server, enabling CQL to be used against all Z39.50
1460 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1461 ZOOM_query object, and submit it using ZOOM_connection_search().
1462 The CQL-to-RPN translation uses a configuration file, the name of
1463 which must be specified in the Connection's "cqlfile" option.
1465 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1466 function, which takes as its start-term parameter a ZOOM_query object
1467 (which may have had either CQL or RPN set into it).
1470 --- 2.1.10 2005/11/29
1472 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1473 GFS to support this as well. Backend handler, bend_srw_update, does the
1474 update work. Code contributed by Ko van der Sloot.
1476 Allow retrieval of Search Result-1 information in ZOOM by the use of
1477 options that are attached to a result set. ZOOM documentation updated
1480 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1481 UTF-8 conversion. Patch by Raj Patel.
1483 Added option -m to GFS to control formatting of timestamps in log file.
1485 Added 'exit' as synonym for 'quit' in yaz-client
1487 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1488 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1489 for the new members. Patch by Ko van der Sloot.
1491 Added support for SRU POST. It is supported for content-type
1492 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1494 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1495 Instead make the library libyaz.la multi-threaded. Threading as a whole
1496 can still be disabled by configure option --disable-threads. Previosly,
1497 with older GLIBCs there were problems with MT libs under Apache. This
1498 has now been fixed a long time ago.
1500 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1503 CQL module modified to be case insensitive for relations/indexes/operations.
1505 Fixed bug in CQL transform code: incorrect value relationModifieder
1508 Added 'show all' command for yaz-client which retrieves all results
1511 Added new yaz-client, xmles, which takes a (private) OID and
1512 a document to be sent as an extended service request.
1514 Describe new yaz-client commands wait_response and set_auto_wait.
1516 Increase TCP/IP listener backlog from 3 (which I am guessing was
1517 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1518 that the socket will queue as many incoming connections as it's able
1519 to handle ongoing connections. In other words, it will never now
1520 refuse a connection that it would be able to handle merely because
1521 it's not got around to accepting() enough of the pending connections
1522 yet. This is the behaviour anyway under Linux, where the listen()
1523 argument is ignored; but not under BSD and on systems such as
1524 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1525 YAZ-based servers should now be uniform across operating systems in
1528 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1529 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1530 This allows yaz-marcdump to read large MARC batches (>2 GB).
1532 Modified all YAZ source files - except the source which is auto-generated
1533 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1536 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1537 corresponding to the existing *_setl() function. These allow option
1538 values containing arbitrary valuues.
1540 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1541 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1542 except that it returns an indicator of whether or not the sort
1543 criterion was accepted (0 for OK, -1 for invalid).
1545 --- 2.1.8 2005/06/07
1547 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1548 MARC output rather than returning "new" buffer.
1550 yaz-client warns about unknown init options.
1552 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1554 --- 2.1.6 2005/05/24
1556 Added support for SRW sort in Generic Frontend Server. Patch
1557 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1558 sortKeys - or NULL if none is provided.
1560 Fixed bug #307: It was impossible to specify indefinite/no timeout
1561 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1564 Added support for multiple languages and charsets to be specified in
1565 ZOOM. Each charset/language is separated by a blank. If negotiation is
1566 in effect in init-response, Option
1567 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1568 Code based on patch by Vasiliy Osadchuk.
1570 Fixed bug #306: infinite recursion that occurred when calling
1571 yaz_log_level_init as the first call (before other log level or
1574 Fixed bug in scan handling in front end server: if preferred-Position-In-
1575 Response was non-present, a NULL pointer referece was performed.
1577 --- 2.1.4 2005/04/26
1579 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1580 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1581 now defined for all those error codes. So instead of putting 109 in
1582 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1583 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1585 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1588 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1590 Program yaz-client now exits and produces an error message if multiple
1591 Z39.50 servers are specified on the command line (none or one allowed
1594 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1597 --- 2.1.2 2005/03/16
1599 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1601 Fixed bug #272: Preserve spacing for CCL terms.
1603 --- 2.1.0 2005/03/14
1605 Added support for virtual hosts and multiple backend servers for
1606 the YAZ frontend server. The configution is XML based and
1607 support specificition of CQL to RPN mappings and explain information.
1608 See section "Virtual Hosts" in the YAZ manual.
1610 Extended OPAC display utility. OPAC display utility renders
1611 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1612 to supplement yaz_marc_decode_wrbuf.
1614 Fixed a bug in MARC decoder that could caused it to crash for some
1615 invalid MARC records. More diagnostics and warnings where added in
1616 XML output (warnings, etc are stored in comments).
1618 --- 2.0.34 2005/02/08
1620 Fixes for UNIX domain sockets. Bug #261.
1622 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1624 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1625 Added yaz_marc_subfield_str which defines subfield lead string which is
1626 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1627 yaz_marc_endline_str which defines end of fields string used in
1628 YAZ_MARC_LINE format. Default string is newline.
1630 Experimental support for MarcXChange. This format can be produced
1631 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1632 http://www.bs.dk/standards/MarcXchange.xsd
1634 Added yaz-client commands scansize that sets maximum number of
1635 entries to be returned by scan.
1637 --- 2.0.32 2005/01/11
1639 Added support for SRW scan in yaz-client and Generic Frontend Server.
1641 * Added whereInList member to SRW Scan Term.
1643 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1645 Fixed NMEM system to return aligned blocks on the smallest boundaries
1646 that are suitably aligned for all possible types on the particular
1647 architecture YAZ is being built for.
1649 --- 2.0.30 2005/01/04
1651 Fixed numerious warnings that was issued with newer versions of GCC.
1653 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1654 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1657 Make YAZ Generic Frontend Server slightly faster.
1659 Enhance (and reduce) logging for Generic Frontend Server.
1661 Revert YAZ log system so that it flushes every write operation
1662 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1664 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1665 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1666 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1667 will effectively disable old definitions.
1669 --- 2.0.28 2004/11/09
1671 Added yaz_log_time_format which specifies log format using
1674 Added yaz_log_module_level which returns mask for a module. Value
1675 is non-zero mask a if module is enabled; zero if disabled.
1677 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1678 in include/yaz/cql.h.
1680 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1682 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1684 Fixed bug #172: RPM builds does not enable SSL.
1686 Doxyfile.in part of dist. Doxyfile generated by configure.
1688 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1689 are given and the corresponding component does not exist.
1691 Extend CCL documentation in YAZ reference. Describe r=r.
1693 --- 2.0.26 2004/10/01
1695 Fixed MARC->MARCXML conversion to properly deal with
1696 fields, subfields, indicators having non-ASCII characters.
1698 Fixed MARC->MARCXML conversion so that ASCII control characters
1699 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1702 Added YAZ GFS support for conversion from Z39.50 surrogate
1703 diagnostics to SRW surrogate diagnostics.
1705 Bug fix: YAZ GFS did not return schema in explainResponse.
1707 --- 2.0.25 2004/09/30
1709 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1710 now converts recordSchema to elementSetName as well as schema URI.
1712 Fixed bug in COMSTACK that prevented HTTP request packages from being
1715 --- 2.0.24 2004/09/29
1717 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1718 does not require white-space before and after the dash in a range, e.g.
1719 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1722 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1723 due to new GCC removing "redundant" code.
1725 Added yaz-client commands scanpos and scanstep that sets preferred
1726 position and step-size for scan.
1728 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1730 Added CCL utility ccl_qual_buf which parses one or more CCL
1731 spec lines in a buffer.
1733 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1734 of name and value - ignoring empty lines and comments.
1736 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1738 Added odr_get_element_path which returns current element path for an
1739 ODR handle. This utility is useful in error handling or user-defined
1742 Added ODR_PRINT utility odr_set_stream which is is a more generic
1743 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1744 to a write function and pointer to close function. The close function - if
1745 non-NULL - will be called during odr_destroy.
1747 Fixed bug in CCL parser where truncation char was not removed from
1748 right side when truncation=both was in effect.
1750 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1753 --- 2.0.23 2004/08/11
1755 Fix buffer overrun in CQL parser when dealing with proximity (%).
1757 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1758 to UTF-8/UCS conversion is now only based on codetables.xml.
1760 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1762 --- 2.0.22 2004/08/06
1764 Add support for more "commit changes" in ZOOM (uses Extended Services).
1766 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1769 Yet another small fix for configure of SSL.
1771 --- 2.0.21 2004/05/14
1773 Fix SSL libs for configure when --with-openssl=DIR is given.
1775 --- 2.0.20 2004/05/10
1777 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1779 SSL comstack now uses yaz.pem certificate file on server side
1780 by default. Certificate filename can be configured by calling
1781 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1783 Fix bug regarding multiple calls to ZOOM_connection_connect.
1785 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1787 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1788 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1790 ZOOM now allows inspection of X509 peer certificate for verification.
1791 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1793 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1794 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1795 as "modular" but it simplifies things.
1797 Added cs_get_peer_certificate to that returns peer X509 PEM.
1799 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1800 NULL if SSL is unavailable.
1802 Documentation about MARC decoding tools.
1804 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1806 --- 2.0.19 2004/03/30
1808 Rename CHANGELOG to NEWS to follow GNU style packing.
1810 Fix bug with missing initialization of member in init_diagnostics.
1811 This bug affects threaded version of GFS server.
1813 --- 2.0.18 2004/03/20
1815 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1818 Ensure zlib.dll is packed with Windows install.
1820 --- 2.0.17 2004/03/17
1822 Fix encoding of xsd:string to use text instead of CDATA.
1824 Fix endless loop in CQL parser with unbalanced ".
1826 Use a more compact way to store MARC-8 conversion tables.
1828 --- 2.0.16 2004/03/16 Debian only
1830 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1833 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1838 --- 2.0.15 2004/03/01
1840 Another fix for decoding of XML packed records.
1842 --- 2.0.14 2004/02/25
1844 Fixes for Chunked encoding. White space not ignored after length spec.
1846 Update NS and use default NS for SRW diagnostic elements.
1848 --- 2.0.13 2004/02/23
1850 Implement ZOOM_resultset_cache_reset which resets record cache.
1852 Implement ZOOM_resultset_sort which sorts a result set.
1854 Implement chunked HTTP transfer.
1856 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1858 --- 2.0.12 2004/02/16
1860 Added member 'schema' to bend_explain_rr structure so that backend
1861 can specify explain record identifier. Defaults to Zeerex 2.0.
1863 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1865 --- 2.0.11 2004/02/16
1867 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1870 Added init command for yaz-client which sends "extra" init request.
1872 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1873 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1875 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1877 Make ZOOM error code for "invalid query".
1879 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1881 --- 2.0.10 2004/02/05
1883 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1886 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1888 Added option -p <file> to make Generic Frontend Server to write PID file.
1890 Added option -D to put Generic Frontend Server in background on its own.
1892 Make ZOOM C recognize option "password". If unset, "pass" is used
1893 (for backwards compatibility).
1895 Fixed a bug in Generic Frontend Server that could make it crash if a
1896 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1899 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1900 Must be issued before open, in order to be in effect.
1902 --- 2.0.9-6 2004/01/12 Debian/Windows
1904 Make the SRU server more picky WRT unknown params, etc.
1906 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1908 New YAZ client command, options, that sets Z39.50 options.
1910 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1911 options from a string of tokens (one token for each option bit).
1913 Update SRW diagnostic code messages.
1915 --- 2.0.9-5 2004/01/07 Debian/Windows
1917 Handle user defined stylesheet for SRW/SRU.
1919 --- 2.0.9-4 2004/01/06 Debian/Windows
1921 Fix bug in decoding of Content-Length.
1923 --- 2.0.9-3 2004/01/06 Debian/Windows
1925 Fix a bug with decoding of XML packed records.
1927 --- 2.0.9-2 2004/01/05 Debian only
1929 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1931 Fix bug in SRW/SRU diagnostics decoding.
1933 --- 2.0.9 2004/01/05
1935 Fixed bug in Generic Frontend Server which could drop records exceeding
1936 preferred message size. Reported and fixed by Irina Dijour.
1938 Fixed calculation of package size for structured records in Generic
1939 Frontend Server. Reported and fixed by Irina Dijour.
1941 Fixed namespace for SRW/SRU diagnostics.
1943 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1945 --- 2.0.8 2003/12/22
1947 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1948 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1951 CQL changes to reflect recent changes to the specification:
1952 * Documentation talks about context sets instead of index sets.
1953 * Documentation talks about indexes instead of qualifiers.
1954 * The CQL-to-PQF transformer's configuration file now uses
1955 "index.set.name = <attributes>" instead of the old form
1956 "qualifier.set.name = <attributes>". (Both forms are still
1957 understood but the latter is deprecated.)
1958 * CQL terms with no explicit index specified are now interpreted as
1959 cql.serverChoice instead of srw.serverChoice (which of course
1960 behaves exactly the same.)
1962 --- 2.0.7 2003/12/16
1964 MARC conversion can now generate ISO2709 output in another
1965 character set. yaz-marcdump uses this facility if you invoke it
1968 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1969 functions from there can be used from C++.
1971 --- 2.0.6 2003/12/04
1973 Frontend server now transfers memory from decoded packages to stream
1976 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1977 references to show up.
1979 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1980 the ZOOM Abstract API. The older names for the same options are still
1981 also supported for the benefit of old applications.
1983 ZOOM-C supports "implementationId" and "implementationVersion" options
1984 to go along with "implementationName". These allow the user code to
1985 specify identification strings to be sent to servers.
1986 Add OID for the new ExtLite attribute set.
1988 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1989 as requested/supplid by Ere Maijala <ere@atp.fi>
1991 For generic frontend server, reverse the order of
1992 "toolkit-supplied / application-supplied" strings sent as implementationId,
1993 Name and Version. Also, remove the spaces around the slash. This brings
1994 the GFS in line with the behaviour of ZOOM-C on the client side.
1996 Add function ZOOM_scanset_display_term.
1998 yaz-client shows scan displayTerm if present.
2000 Utility yaz-iconv is now installed by default along with the man page
2003 Extend configure check for OpenSSL to use pkg-config where available (such
2006 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2007 server to specify uid/gid/mask for socket using the format
2008 unix:[user=uid,][group=gid,][umask=mask,]file=path
2009 If file= is omitted the existing format is assumed, e.g.
2011 in which case the mask is 0666 (rw for everybody).
2013 Major restructure of YAZ source. All source in libyaz is in src directory.
2014 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2015 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2017 Added man page for utility yaz-marcdump (used to be called marcdump).
2018 yaz-marcdump is installed by 'make install'.
2020 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2021 of incoming package failed.
2023 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2025 Change prototype of odr_perror: add const to message string.
2027 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2029 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2030 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2031 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2032 DNS lookup. There should not be any compatibility problems with this
2033 assuming that blocking=1 or 0 is used.
2035 Fix bad reference in UNIX comstack in function cs_addrstr.
2037 Fix for compilation on AIX.
2039 The generic front-end server (server/seshigh.c) now supports returning
2040 Init diagnostics to the client in User-information-field, in
2041 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2044 --- 2.0.4 2003/09/04
2046 Allow any CQL relation (not just all,any,exact,scr).
2048 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2049 that features the same UI.
2051 Implemented command update0 in YAZ client which is equivalent to
2052 update but uses old of Ext Update ASN.1.
2054 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2055 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2056 Previously no OID was used for this info.
2058 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2059 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2060 returns 'malformed search term' otherwise.
2062 SortResponse member resultCount now set to NULL in sort handler of
2065 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2068 Add three new utility functions for translating OIDs between various
2069 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2070 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2071 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2072 char *oid_to_dotstring(const int *oid, char *oidbuf);
2073 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2075 Reverted modifications for ES Update definition for z_IU0Update
2076 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2077 is back to YAZ 2.0.2.
2079 String value attributes for CCL parser.
2081 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2082 which their FirstSearch server returns in Init responses, sometimes
2083 carrying useful diagnostic information when Init fails. This has the
2084 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2085 "z39.50/oclcui.asn", where its definition is somewhat different from
2086 what OCLC document on their web-site, as required to interoperate with
2089 Support for anonymous authentication in yaz-client. Use the command
2092 * Fix the OID of the Index Data-local "admin" Extended Service from
2093 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2094 the 1000, which indicates a locally-defined OID, was a mistake.
2096 --- 2.0.3 2003/06/20
2098 Fix CCL directive @case handling so that it affects string match for
2099 both CCL keywords and qualifiers.
2101 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2102 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2103 Decoder has been updated with ASN.1 changes as listed in
2104 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2105 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2106 z_IUUpdate, remains unchanged.
2108 ZOOM_record_get may now return a record in a specific character set.
2109 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2110 "from" is the character set of record as returned by target. "to" is
2111 the character set to be returned. If omitted, "to" is UTF-8.
2113 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2115 New ODR utility, odr_getelement, which returns name of element for
2116 which encoding/decoding failed.
2118 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2119 in cases where a required element was omitted.
2121 Bug fix: some MARC8 sequences were not converted.
2123 New ZOOM option "step" which specifies number of records to be
2124 retrieved in one chunk. Used in conjunction with "start" and "count".
2126 SRW support for yaz-client. Use scheme http: to use it, e.g.
2129 yaz-client no longer does (un)intelligent character set conversions
2130 by default. Can be enabled with charset and marc_charset commands.
2132 xmalloc trace fix for 64-bit systems such as DEC alpha.
2134 Solaris 2.6 compile fix.
2136 New function, cql_strerror() translates SRW error codes, as returned
2137 by cql_transform_error(), into human-readable English strings. Used
2138 in yaz-client diagnostics when appropriate.
2140 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2141 converts it into a type-1 query which is sent to the server. This
2142 makes CQL available for use with all Z-servers, as opposed to the tiny
2143 minority that can handle CQL queries themselves.
2145 --- 2.0.2 2003/04/28
2147 New Debian package layout similar to the Redhat Package layout.
2149 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2150 and search result respectively.
2152 --- 2.0.1 2003/04/25
2154 Redhat package is now several packages: libyaz (runtime libraries),
2155 libyaz-devel (development and documentation, and yaz (utility programs).
2156 Package spec file by Morten Bogeskov.
2158 New member 'schema' in struct bend_fetch_rr which the name of requested
2159 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2160 handler MAY set this to reflect the schema of the returned record.
2162 New member 'display_term' in struct scan_entry. GFS now sets member entries
2163 and allocates scan entries to be filled by user scan handler. In previous
2164 version, entries member was allocated by the scan handler. That still works,
2165 but the GFS will ignore member display_term - assuming it was NOT set by
2166 the handler. The fact that the GFS now allocates the entries both allows
2167 for new members and makes a scan handler easier to write.
2169 Fix CQL lex buffer overflow.
2171 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2172 SRU default recordPacking is string.
2174 SRU protocol support for frontend server.
2176 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2178 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2180 Added scan for the ZOOM shell (zoomsh).
2184 * String Identifers for Schemas (Amendment 5).
2185 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2186 Old definition for schema
2187 Odr_oid *schema; /* OPT */
2192 Z_InternationalString *uri;
2193 #define Z_Schema_oid 1
2194 #define Z_Schema_uri 2
2197 * resultCount parameter to Sort Response (Amendment 1).
2198 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2200 Support for SRW 1.0 over HTTP. This is an optional feature and
2201 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2204 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2205 on the same port. SRW SearchRetrieveRequests are mapped
2206 to bend_init,bend_search,bend_fetch,bend_close.
2208 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2210 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2211 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2213 ZOOM connections are SRW based if schem http is used for hostname
2214 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2215 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2217 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2218 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2219 distance=n, order=true/false, relation=le, prox unit=word. If
2220 n is omitted, distance 1 is used.
2222 Fixed problem with C compiler include path in wrong order.
2224 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2225 on Solaris. Patch from Ko van der Sloot.
2227 New MARC decode API. All new functions operate on a yaz_marc_t
2228 handle. The most important new functions are: yaz_marc_create,
2229 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2230 decode and destroy respectively. Decoder can produce formats
2231 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2232 include/yaz/marcdisp.h.
2234 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2235 to UTF-8, UCS-32, wchar_t or Latin-1.
2237 * Prototypes for yaz_iconv_-functions moved to separate header
2238 include/yaz/yaz-iconv.h.
2240 Make a few private functions 'static' in unix.c. This prevents
2241 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2243 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2244 are set when Init Response is received.
2246 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2247 but returns diagnostic set as well.
2249 New function yaz_strerror which is a portable wrapper for
2250 strerror/strerror_r/GetLastMessage.
2252 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2253 is returned for MARC. If type is "oai", then OAI MARC is returned.
2255 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2258 --- 1.9.2 2002/11/26
2260 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2262 Fix bad race conditions on SIGTERM and terminate gracefully in
2265 Move retrieval (data1) module to Zebra since nobody seems to be
2268 Add GRS-1 render for ZOOM using same format as yaz-client.
2270 --- 1.9.1 2002/10/05
2272 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2274 Fix broken ESpec handling in data1 module.
2276 SGML reader parses comments and makes them part of the data1 tree.
2278 Added several type casts so that YAZ compiles as C++ code.
2280 ZOOM didn't handle PDU encoding failures properly.
2282 Added more Bib-1 diagnostics (approved extensions).
2284 GNU configure: better check for iconv.
2286 More portable use of accept, getpeername. Check for socklen_t. Use
2287 int/size_t if socklen_t is not defined.
2291 PQF parser rejects bad queries - including those with extra
2292 characters in them. PQF parser used to silently ignore that.
2293 Cleaner API for PQF added, which allows you to get detailed
2294 error information for bad queries (see yaz/pquery.h).
2296 Fixed bug in ZOOM_record_get for type "database".
2298 Implemented mini iconv library supporting conversions between
2299 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2301 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2303 --- 1.8.9 2002/08/20
2305 Fixed ZOOM C record cache so that preferredRecordSyntax and
2306 elementSetName is used to check for already fetched records.
2308 --- 1.8.8 2002/08/02
2310 Added three members in bend_initrequest structure to facilitate
2311 character set negotiation.
2313 Fixed a bug in frontend server that could cause indefinite
2314 loops under rare conditions.
2316 Revised character set utilities (charneg.h) so that encoding
2317 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2319 For PQF, directive @term <type> sets term type for Scan/Search.
2320 Here <type> is general, string, numeric, null. The term type
2321 is inherited - just like @attr.
2323 New call odr_set_charset that sets character set conversion for
2324 international-strings on a ODR stream. Prototype is:
2325 int odr_set_charset(ODR o, const char *to, const char *from);
2326 The InternationalString is still represented as C string in YAZ
2327 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2328 won't). On the protocol level, you can use any encoding.
2330 Support for UNIX sockets in ZOOM.
2332 Solaris recv sometimes returns errno == ENOENT. It is treated as
2333 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2335 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2336 both client and server. Code by Morten Bogeskov.
2338 --- 1.8.7 2002/05/22
2340 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2341 that they can be used directly from Visual Basic. You must recompile
2342 your windows APP if you're using ZOOM.
2344 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2345 Commands "lang" and "charset" sets language and character set respectively.
2346 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2347 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2349 Attributes from multiple CCL fields may be OR'ed rather than merged
2350 using directive "@field or". Fields are still merged by default -
2351 equivalent to "@field merge".
2353 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2356 Fixed bug in zget for parameter ExtendedServicesResponse.
2360 --- 1.8.6 2002/03/25
2362 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2364 Client displays USR.1:SearchResult-1 (hits per term).
2366 Additional Search Info for search in Generic Frontend Server.
2368 Fixed CCL parsing of "field=s".
2370 WIN32 installer - using the excellent NSIS software from nullsoft.
2372 Fixed CCL parsing of "field = - <number>".
2374 Added function yaz_marc_decode that decodes MARC for line mode
2375 display or XML (similar to that used by JZKit).
2377 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2378 Z39.50. But ISO/ILL was, however.
2380 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2381 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2383 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2384 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2386 --- 1.8.5 2002/02/03
2388 New YAZ client features: Command completion and new commands:
2389 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2390 Code provided by Jacob Poulsen.
2392 New call oid_trav, that visits all registered OIDs via callback.
2394 Function ZOOM_record_get now returns const char pointer rather than
2395 void pointer. It saves a lot of type casts.
2397 For YAZ client, command "auth" now allows you to set authentication
2398 in IdPass style. It is enabled when three tokens are given - order
2399 is user, group and password.
2401 Fix memory leaks in MARC record handling for ZOOM.
2403 New option for YAZ client, -k <kilobytes> that sets
2404 maximum record size. Similar to -k option for generic frontend
2405 server and yaz-ztest.
2407 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2409 Prefix query parser reports "fail" when bad attribute set is given.
2411 Fix in MARC decoder. Proximity logging. Fix for attribute set
2412 in scan handler for server. Patches by Shigeru Ishida.
2414 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2417 Configure option --with-openssl=<dir> now works when a directory is
2418 specified. Patch provided by Morten Bogeskov.
2420 New option for YAZ client, -u <auth>, that sets authentication.
2422 ZOOM fix: error information was sometimes "missing", since error
2423 was cleared/reset too when it shouldn't.
2425 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2427 --- 1.8.4 2002/01/04
2429 Scan for ZOOM API. New object ZOOM_scanset. New functions
2430 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2431 ZOOM_scanset_destroy.
2433 New ZOOM function, ZOOM_connection_last_event, that returns type
2434 of last event (such as "receive data", "send data", "apdu received",
2437 New ZOOM option, schema, that specifies schema for retrieval.
2439 New CCL feature. Qualifiers can be aliases for one or more
2440 other qualifiers (if more than one is given, OR is used).
2442 ZOOM uses named result sets if target supports it.
2444 Two new YAZ client commands: . (dot, which sources a script of YAZ
2445 client commands), and ! (to execute shell command.). Implemented
2448 Working on Debian packages.
2450 --- 1.8.3 2001/11/19
2452 YAZ client enables named result sets only if target supports it.
2454 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2456 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2457 with key="host" to get same result.
2459 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2460 Function Z3950_resultset_record(s) returns references to records
2461 "owned" by resultset. To become owner use Z3950_record_clone.
2463 Function z_ext_record handles Extended Services. Thanks to
2466 --- 1.8.2 2001/11/12
2468 CCL Parser fix: ignore token comma when dealing with and-lists.
2470 Documentation updates for COMSTACK.
2472 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2473 Changed prototype Z3950_records. For some functions, int parameters
2474 were changed to size_t.
2476 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2479 New MARC decode/display function, marc_display_exl, which properly rejects
2480 non-ISO2709 records. YAZ client uses it.
2482 --- 1.8.1 2001/10/29
2484 Fix bug: local attribute set wasn't set correctly in PQF strings.
2488 * Old Z39.50 codecs no longer supported.
2490 Added ZOOM C binding. See http://zoom.z3950.org/
2492 Renamed states for COMSTACKs to avoid confusion with events.
2494 Implemented cs_look and proper cs_rcvconnect.
2496 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2498 Configure detects POSIX threads on OpenBSD.
2500 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2501 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2503 When error is returned from present handler, non-surrogate diagnostic
2504 is returned in present response (and fetch handler is no longer called).
2506 * Minor adjustments to pquery parser (PQF). Token characters may be
2507 escaped by using backslash (C-style).
2509 PQF parser allows string attribute values to be specified. For @attr,
2510 non-numeric characters after the equal-sign are treated as strings
2511 (e.g. @attr 9=title).
2513 CCL trunction character may be defined (@truncation in file)
2515 * function zget_ExtendedServicesRequest sets waitAction to
2516 waitIfPossible (was wait).
2518 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2521 CCL operator names may be set in field definition files (CCL_bibset).
2522 See ccl/bib1 for an example.
2524 Fixes in ASN.1 compiler for C++ compatibility.
2526 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2527 and "op_or" to avoid conflict with C++.
2529 Fixed problem with GNU readline detection on Redhat 7.0.
2531 Added step-size for Scan backend handler.
2533 Fixed bug that made the frontend server crash when no attribute
2534 set was specified for scan.
2536 Front-end server automatically switches to original working directory
2537 when installed as an NT service. Previously -w had to be specified to
2540 Added extended attributes for retrieval module (data1), so that data1
2541 records carry d1_readXML/SGML attributes. d1_read also supports
2542 null-data rules ( <tag/>)
2544 On UNIX when POSIX threads are available, a separate library libyazthread
2545 is created. Programmers should link with that library and the yaz library
2546 when using threads. The reason for the split was that some applications
2547 on Linux, such as Apache, doesn't work well when using shared objects that
2550 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2551 (or any frontend server) in SSL mode by specifying ssl: followed by
2552 address. Only tested on UNIX.
2554 Added feature for CCL module. Virtual structure s=al or s=ol generates
2555 and-list and or-list respectively instead of phrase search.
2559 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2560 log_mask_str. This was done to avoid name conflicts with other libraries
2561 (such as other PHP extensions).
2563 Added raw OID member for preferred record syntax (request_format_raw)
2564 and returned record syntax (output_format_raw) for backend fetch method.
2566 Config file yaz-config now accepts options so that it returns specific
2567 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2569 Shared library support for UNIX using GNU libtool.
2571 * Modified backend interface. Request/Response struct's replaced by
2572 one read/write C struct. For example bend_fetchrequest and
2573 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2574 Every handler - even search has to be registered in bend_init
2575 handler. This means that the YAZ library no longer refers to
2576 external functions and it makes it possible to make the whole
2577 thing a single DLL/SO.
2579 Added Segment handler for backend server.
2581 Added Zmbol/Zebra administrative functions to YAZ client.
2583 Threaded frontend server on UNIX (when POSIX Threads are available).
2584 Starting the server with option -T enables multi-threading.
2588 Added configure option --enable-comp/disable-comp to control use
2589 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2590 located in sub directory asn.
2592 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2593 in ${exec_prefix}/bin along with the other programs yaz-client and
2596 GNU automake used to maintain makefiles.
2598 Added several OID's.
2600 Changed retrieval module so that we can load records with no abstract
2601 syntax defined. Tagpaths in these records are fully composed of string
2604 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2608 On UNIX, the generated makefile now supports a proper 'make install'.
2609 The prefix can be set via GNU configure to set the install location
2610 (default is /usr/local).
2612 * YAZ programs client and ztest were renamed to yaz-client and
2613 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2614 locations, such as /usr/bin,/usr/local/bin,etc.
2616 * YAZ Header files were moved from include to include/yaz. YAZ Header
2617 files are referred to as include <yaz/log.h> rather than <log.h>.
2618 The YAZ include path (-I ..) is therefore the same as before. Programmers
2619 should update their #include statements or use -Ipath/include/yaz
2620 instead. The main motivation for doing this change is that YAZ header files
2621 can be installed in "standard" locations /usr/include,/usr/local/include
2622 without introducing conflicts, since ALL YAZ header files are stored
2623 in subdirectory yaz (under /usr/include for example).
2625 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2626 rather than project/workspace files. We switched because project files
2627 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2630 Changed name of logging function, logf, to yaz_log, to prevent name
2631 clash with some math-log functions. The YAZ header log.h defines logf
2632 to yaz_log (#define) so there should be no incompatibilities by this
2635 Added bend_start/bend_stop handlers for server. These handler are
2636 called on start/stop of server. For windows they are called whenever
2637 a service is started/stopped.
2639 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2640 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2641 in util/yc.tcl. The auto-generated C code structures are, in a few
2642 cases, incompatible with the old decoders. There are differences in the
2643 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2644 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2645 The preprocessor variable ASN_COMPILED is defined when the compiled
2646 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2647 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2648 wish to use the old encoders/decoders you can specify --disable-yc
2651 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2652 version so that it supports both new - and old version of DB Update
2654 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2655 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2656 change. The name parameter can be set to 0 in which no name is specified
2657 for the construction. The macros odr_implicit and odr_explicit sets name
2658 parameter to zero for the construction involved. New macros
2659 odr_implicit_tag and odr_explicit_tag are similar to the others,
2660 except that a name parameter is added. For programmers' that don't use
2661 ODR they probably only need to change the call to z_APDU and z_External.
2663 Added access control facility by interfacing the TCP wrapper library.
2664 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2665 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2666 name of the daemon and enables the access control as specified in
2667 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2669 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2670 den Dool <H.M.vdnDool@kub.nl>.
2672 Added reference ID parameter to most functions in server API - refer
2673 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2675 Changed name of ccl library to libccl.a (was ccl.a).
2677 Fixed bug in decoder for Explain (Category TargetInfo).
2679 Added support for GNU readline in client. Thanks to Jacob Poulsen
2680 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2682 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2683 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2684 IMPLEMENTATION! This change was made to the development version before
2685 the ZIG decided to retract the amendment. If any users MUST be
2686 compatible with the original Update definition, PLEASE CONTACT US, and
2687 we will include a separate definition corresponding to the old Update
2688 ES. Note that because of the change to the ASN.1 of the
2689 TaskPackageRecordStructure we cannot define a single structure that
2690 will support both versions.
2692 * Added const modifier to buffer parameter for some ODR/BER encoding
2693 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2694 completeWAIS, odr_dumpBER.
2696 Fixed bug in client.c which caused a crash when a scanResponse didn't
2697 contain positionOfTerm.
2699 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2700 * will cause an error in a client if a non-YAZ target sends both a
2701 * list of Scan entries and non-surrogate diagnostics.
2703 Retrieval module enhancements. Tag sets may be typed in the reference
2704 to it. From the .abs-file the "tagset" directive takes a third optional
2705 integer type for the tag set referenced. From a .tag-file the "include"
2706 directive takes a third optional type as well. The old "type" directive
2707 in the tag set itself is still recognized but acts as the default type
2710 Backend interface change. Individual Scan terms returned from bend_scan
2711 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2712 in include/backend.h.
2714 Retrieval module enhancements. Multiple tag sets and attribute sets may
2715 be specified in abstract syntax specs. Revised the error/warning for
2716 logging messages reported by the retrieval module when reading the
2719 Object Identifier system (oid_..) changed. The API is backwards
2720 compatible but the oid-routines now allocates new OID's when needed.
2721 Raw OID's may be specified in oid_getvalbyname.
2723 YAZ now uses GNU configure to generate Makefile(s).
2725 * Minor changes in some of the member names of DeleteResultSetRequest and
2726 DeleteResultSetResponse. See include/proto.h.
2728 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2729 and added member 'languages' in TargetInfo (which was missing).
2731 Changed the way attribute sets are handled in the retrieval
2732 module. These are now cached, just like the abstract syntaxes
2735 Changed YAZ so that it links with compiled ASN.1.
2737 Added Explain-schema definitions and mapping routines. The following
2738 Explain categories have been implemented: AttributeDetails,
2739 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2741 Fixed minor bug in Windows version of Server Library.
2743 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2745 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2747 Added EXTERNAL: UNIverse Resource Report (non-standard).
2749 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2750 ENUMERATED and SET OF.
2752 * Added 'const' to some of the char pointer arguments for the
2753 functions, data1_read_node, data1_getelementbytagname,
2754 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2757 Fixed bug in data1_insert_taggeddata - the last_child member of
2758 parent wasn't initialised.
2760 * Changed data1_read_record and data1_read_node so that the supplied
2761 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2762 doesn't refer to any parts of the "SGML"-buffer.
2764 Fixed bug in server library (Windows version of statserv_remove).
2766 * Changed code so that it compiles as C++. The type definition
2767 of Odr_fun which is a member of Odr_arm was changed. The result is,
2768 that an explicit typecast is needed for the fun pointer when
2769 using Odr_arm - as in:
2770 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2772 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2774 Implemented the new structured date and time definition as approved
2775 by the ZIG. Added schemaId element to the specificTag in Espec-1
2776 (also approved at the last ZIG). Thanks to RVDM.
2778 Added some Object identifiers (RVDM).
2780 Changed the Update Extended Service (RVDM).
2782 Added command "refid" to client which specifies referenceId for
2783 the following requests.
2785 Implemented extended service handling for server. See ztest.c
2786 for an example as well as backend.h. New handlers are registerd
2787 in the Init handler.
2789 * Changed interface for sort in server.
2791 Added new members to statserv_options_block. It allows a server
2792 to read options from another source than just the command line. Thanks
2793 to Charles Woodfield.
2795 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2796 renamed to zboolean. Some C++ compilers complained about the name.
2798 Minor changes to gils.abs. Added index 's' (sort) on title
2799 and date/time-last-modified.
2801 --- 1.4pl2 1998/1/30
2803 Fixed bug in server library regarding inetd mode (-i). This bug
2804 was introduced by release 1.4.
2806 --- 1.4pl1 1998/1/29
2808 Added sort facility in client and backend server interface.
2810 Fixed problem with dependencies in Makefile(s).
2812 Fixed bugs for encoders/decoders of extended services and
2815 Implemented sub-tree feature for schemas. Sub-trees are
2816 referenced in *.abs-files. See explain.abs for an example
2817 of the use of this feature.
2819 Modified bib1.att; local attributes for ANY didn't include
2820 ANY itself (only affects use of the retrieval module).
2822 Fixed bug in plain SGML reader in function data1_read_node:
2823 tags with prefix "var" was incorrectly interpreted as variants.
2825 Added feature "sub-schemas" to enable references to - and definitions
2826 of - group of elements.
2828 * Removed member parent from type data1_element (in data1.h).
2830 Implemented function odr_nullval() that returns the value of
2833 * Removed member num_children from data1_node (in data1.h).
2835 Made NT service interface part of the server library. The
2836 function statserv_main uses the NT service when required and
2837 calls the statserv_start / statserv_close routines.
2839 Routine zget_SearchRequest and zget_PresentRequest fills
2840 resultSetName/Id member with "default" instead of "Default".
2842 Fixed memory leak in server. Request queue member wasn't freed.
2844 Fixed nmem_exit so that memory is freed.
2848 Revised the CCL parser utility to be thread safe.
2850 Added function, oid_ent_to_oid, to replace the function
2851 oid_getoidbyent, which is not thread safe.
2853 * Added nmem_init and nmem_exit to initialize and release
2854 NMEM resources. Function nmem_init should be called once in the
2855 initial thread before NMEM/ODR is used. statserv.c and client.c
2856 have been changed accordingly. The change was necessary to make
2857 NMEM thread safe. The NMEM memory pool is shared amongst threads
2858 in a process. Unix-based applications will still work fine without
2861 Added NT Services interface for the the Z39.50 (statserv) Server.
2862 Refer to the ztest.c source on the usage.
2864 Windows 95/NT port using MSVC5.0. Project files are included in the
2867 * Defined new 'global' handle for the retrieval (data1) system. The
2868 new handled, data1_handle, describes the state of the data1 system.
2869 This handle is passed as first argument to virtually all
2870 data1 related routines. The functions data1_create and data1_destroy
2871 creates and destroys a data1 handle respectively.
2873 Added ODR encode stream member to all backend request structures
2874 init, search, scan etc. This stream should be used to allocate all
2875 memory used for the response when thread safe operation is needed.
2877 Changed the comstack utility, cs_addstr, to be thread safe. The
2878 returned hostname string returned by the function is now part the
2881 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2882 function. The cs_straddr takes a COMSTACK handle as argument, so this
2883 function must be used after cs_create and before bind/connect.
2884 This function is thread safe.
2886 Moved test server to 'ztest' directory - generic server code still
2887 in 'server' directory.
2889 Made prefix query (pquery.c) utility thread safe.
2891 Added new function modifier YAZ_EXPORT to 'export' public DLL
2892 functions when using windows (see include/yconfig.h).
2894 Added definitions to the OID database (util/oid.c) (RVDM).
2896 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2898 Added call to ccl_rpn_delete in client program.
2900 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2901 release of RPN structure.
2903 Added support for C++, headers uses extern "C" for public definitions.
2904 With input from RVDM.
2906 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2907 Thanks to Ronald van der Meer (RVDM).
2909 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2911 Added support for private extensions to the OID database
2912 (oid_setprivateoids()). Thanks to RVDM.
2914 Added optional, physical ANY (key replication)
2916 Fixed null-reference problem in GRS-1 output filter.
2918 Proximity operator added to Prefix Query Format (PQF).
2920 In test client command "base" accepts multiple databases.
2922 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2926 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2928 Smallish bug-fixes in the new encoders/decoders (explain).
2930 Bug fixed in DeleteRequest.
2932 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2934 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2936 Added SOIF syntax (using private OID for now) to retrieval module and client.
2938 Added Update extended service.
2940 Added SearchResult-1 additional info structure.
2942 Added optional CCL (ISO8777) interpreter as separate module. Available
2945 --- 1.2 1996/6/10 (1st anniversary release)
2947 Added Summary record syntax. Lightly tested.
2949 Added OPAC record syntax. Untested.
2951 Added ResourceReport service encoders/decoders. Untested.
2953 Fixed bug in z_Unit - wrong tagging on unitSystem.
2955 Fixed bug in the DiagRecs decoder.
2957 Added options for max PDU size and session timeout to frontend-server.
2959 Added documentation of query-language parsers and other supporting utilities.
2961 [frontend-server] Added Attribute set to the bend_scanrequest API.
2963 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2964 surrogate diagnostics were generated.
2966 [retrieval] Allow multiple local values for attribute.
2968 [retrieval] Allow multiple attributes per element in .abs files. index type.
2970 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2972 --- 1.1pl2 1996/4/10
2974 Minor changes, mostly specific to Zebra's requirements (retrieval)
2978 Repaired bug in frontend server when running multiple listening
2979 endpoints in dynamic mode.
2981 z_External() now won't break if a known, ASN.1 value comes encapsulated
2982 in an octet-string. The value will pass through unmodified in an Odr_oct.
2984 Added a bit of code to the demo client to decode & display
2985 ASN.1-structured records represented in the octet-aligned branch of
2986 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2988 Added z_ext_getentbyref() to the ASN module. Doc updated.
2990 * Completed the SCAN definition in the ASN module. This may break SCAN
2991 code based on older YAZ-versions at compile-time. The fix is easy -
2994 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2995 under the SCAN definition. Remember to initialize this, server-people.
2997 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2998 that this does not extend to ODR and ASN.
3000 Comstack allows insertion of established socket (primarily for
3001 inetd-operation of servers). Doc updated.
3003 Front-end server can now start from the inetd in TCP mode. Doc
3006 --- 1.0pl4 1996/1/24
3010 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3011 the rank and record number.
3013 Adjustments to the frontend server.
3015 Fixed diagnostic BER dumper. It ignored the file argument.
3019 Various changes to retrieval module.
3021 Changed the union discriminators of the protocol files from enums to
3022 ints paired with #defines.
3024 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3027 *Changed operator in the RPN structure to 'roperator', again to avoid a
3030 Fixed problems in Explain decoders/encoders.
3032 --- 1.0pl2 1995/12/6
3034 Memory bug in log module fixed.
3036 --- 1.0pl1 1995/12/5
3038 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3040 Bug in Explain DatabaseInfo module fixed.
3042 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3046 The shift to v1.0 signals that we now consider the *core* functionality
3047 of YAZ reasonably stable (the core being more or less equivalent to
3048 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3049 tested (Explain not at all - though that will happen soonish).
3051 Minor changes to code to support Windows port.
3053 Various minor changes after we're getting to use GRS-1 & co. more.
3055 Added Espec-1 format.
3057 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3058 of the protocol and it cannot be selected when encoding (maps into 'string'
3059 when decoding). Needed to talk to some servers.
3061 Demo client can request simple element set names.
3063 Added Diagnostic Format encoders/decoders.
3065 Added simple Close handling to frontend server (no hooks for resource
3066 reporting yet), and demonstration client.
3068 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3070 --- 1.0b3 1995/08/24
3072 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3073 handled incorrectly when records were requested in the searchResponse. This
3074 will only affect you if you use the frontend-server.
3076 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3077 Test-client will ask for and print GRS1. Ztest will return dummy records
3080 Added Explain encoders/decoders to the service-level API. Untested.
3082 Added Extended Services: Item Order encoders and decoders to the Service-
3083 level API. Untested. We could use a recent copy of the pertinent bits
3084 of the ILL protocol to add those bits.
3086 Added diagnostic format 1 encoders/decoders to the service-level API.
3089 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3090 odr_cons.c, which causes a more correct output.
3092 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3093 was always set to 0 when no records were requested in the searchRequest.
3095 * Added better external-handling. This shouldn't harm old code that
3096 *encodes* externals. It can break code that looks for a
3097 'single-ASN1-type' representation, since those types that are known
3098 are now decoded immediately. Look at the SUTRS sample code in
3099 seshigh.c and client.c. Documentation updated.
3101 Handling of structured records in bend_fetchresponse. Length -1 marks
3102 structured record, type is deduced from format field.
3104 --- 1.0b2 1995/06/27
3105 Fairly quick maintenance release to add SUTRS support.
3107 Fixed handling of SUTRS records in the demonstration client.
3109 * Added format field to the bend_fetchrequest and bend_fetchresponce
3110 structures of the backend API (frontend server). When the record is
3111 returned, the value of the format field is mapped to an OID. The
3112 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
