3 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
4 sequence is treated as one. For example, &&a=b&&&c& is identical to
9 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
10 APDUs for a connection to a WRBUF.
14 Fix cql_sortby_to_sortkeys. Completely broken before.
16 Make CCL's @truncation work again.
20 New ZOOM connection setting: tproxy. It's like proxy, but does not
21 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
22 to set resolved address + port for a connection outside ZOOM itself.
24 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
28 Fix uninitialized variable in Solr spell support (could cause SEGV
29 for SRU response decoding).
31 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
32 back-end's addinfo through into the ZOOM response addinfo.
34 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
35 they are separated by a colon and a space rather than simply
40 Add support for Solr spell-checking/suggestions through ZOOM.
41 If a Solr target has been configured correctly for spelling-checking
42 and suggestions, these will now be returned on the ResultSet option
43 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
47 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
48 with a flag whether to substitute escape sequences or not.
52 Fix nmem_strsplit_escape to substitute escape char properly.
54 New option for zoomsh -e , which makes it abort on first error and
55 return process exit code to indicate success/failure.
57 YAZ options utility supports special option -- which makes all it treat
58 all following arguments as non-options.
62 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
63 searched if absolute filename is given.
65 Fix conv_xslt() error-reporting when stylesheet is not found.
66 (The value of fullpath is meaningless in this situation.)
70 Fix problem in CQL sort node creation: un-initialized memory.
72 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
73 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
74 CQL sortby depending on whether Type-1 or CQL is actually sent to the
77 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
78 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
80 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
81 will make it possible to use both single-character mask (#) and wildcard (?)
82 in CCL . Throw diagnostic for left truncation because that is not supported
87 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
88 cases using escapes (\-sequences) and masking.
90 PQF parse fix: A trailing backslash followed by end-of-string (\0)
91 would result in a read one byte beyond string.
93 rpn2ccl may use Z39.50 masking for terms (t=z).
95 ICU check fix. Don't include library -lCrun on Solaris, unless present.
97 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
98 not --cppflags (which seeems like an error in icu-config).
100 --- 4.2.12 2011/08/27 RPM package only
102 cql2ccl: fix conversion of terms: operator characters were not
105 --- 4.2.11 2011/08/25 RPM package only
107 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
108 CCL parser will map both # and ? to their regular expression
109 quivalents (. and .*).
111 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
112 of reserved CQL characters.
114 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
115 is, so that they are passed through.
117 --- 4.2.10 2011/08/24
119 ZOOM SRU mode: more aggressive re-connect.
121 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
122 made available as a utility function, declared in <yaz/logrpn.h>
124 rpn2cql_structure() supports proximity nodes (except that the Type-1
125 proximity node's "exclusion" binary is ignored, as there is no way to
126 express that in CQL). Fixes bug #4564.
130 Fix SEGV that could occur if set command of zoomsh was given without
131 value (2nd argument).
133 Fix SEGV that could occur if unsupported transport was given for
134 COMSTACK - say https (when SSL was unavailable).
136 Build yaz-url on Windows too.
140 New utility to get web content. Header is url.h. A command line tool
141 yaz-url is part of the distribution and packages.
143 Fixes for SSL COMSTACK (when gnutls is in use).
145 New functions yaz_base64{encode,decode}. Header is base64.h.
149 ZOOM C includes HTTP response buffer as additional info if it fails
150 to decode the SRU response.
152 Make wrbuf_json_puts available.
156 zoom: throw diagnostic for invalid value for option "sru". Before a
157 bad SRU request was sent.
159 Adding new utility wrbuf_vp_puts.
161 Add cclxmlconfig.obj to win/makefile. It was missing completely.
165 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
166 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
167 redirect was used at the same time.
169 MARC line mode decoding: be less picky about length given - first
170 5 digits of header that is.
172 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
174 Changes to decoding of SRU records: a record with recordPacking=xml is
175 modified with a new root element <yaz_record> if the recordData contains
176 multiple children elements. This is to make the record XML parseable
179 RPN to SOLR conversion: encode special characters.
181 Generic Frontend Server: fix uinitialized member, stepSize.
185 Fix a bug in SRU decoding of records.. The database records stored
186 had un-initialized memory, but it would only be seen with yaz_record_render
187 and type_spec="ext" .
189 Fix a bug in ccl_qual_dup introduced in 4.2.3.
193 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
197 Add new utilities to convert from CQL to CCL . These utilities have
198 prefix cql_to_ccl defined in cql.h.
200 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
201 lead to memory heap corruptions when ICU utilities were in use.
205 Make compilation work without Libxml2.
207 yaz-client: remove redundant blanks in display of searchResult-1 term
212 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
213 resulting CQL node (tree) in a new node CQL_NODE_SORT.
215 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
216 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
217 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
218 Note that the CQL sortby spec is only converted when the GFS is already
219 converting from CQL to RPN (cql2rpn element).
221 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
222 specify whether to collapse delimitors or not. The existing nmem_strsplit
223 do collapse (collapse parameter = 1).
225 Windows installer: For NSIS, set InstallDir depending on x86/x64.
227 Rename internal func yaz_use_attribute_create. While non-static, this
228 function is not declared in a public header.
232 Add -lCrun when linking with ICU on Solaris.
234 More quicks character set conversions for OPAC records.
238 fix problem with record_render: records were converted (character set
239 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
243 SRU: add methods for handling DADS SRU-proxy facets.
245 Separate OPAC record character set for ZOOM_record. yaz_record_render
246 allows a character set given as charset=from/opacfrom,to where 'from' is
247 the character set of a bibliographic record, 'opacfrom' is character set
248 of OPAC record and 'to' is the target character set.
252 yaz-client: show may XML format records. Command show followed by 'format'
253 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
256 src/stemmer.c: Avoid using unnamed union. It is not supported by some
259 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
262 Update yaz.spec to operate on both SLES11 / Centos 5.5.
264 RPM: Release includes 'indexdata' name. Use indexdata in release name so
265 this package can be distinguished from other vendors.
267 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
268 as determined by configure
270 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
272 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
273 returns no error and no record, the present request is considered
274 partial (only a subset of the records could be returned by backend), and
275 so it is appropriate to set Present Status to partial-4.
279 Move yaz-config man pages to section 1.
281 More documentation about SOLR.
283 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
284 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
285 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
286 peers on some Linux systems. However, in general that does not work
287 so YAZ can not rely on that to work. Debian changed behavior in this
288 respect from Debian lenny to Debian squeeze (still testing as of Oct
290 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
292 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
296 Fix yaz-config output: echo_source not set correctly by configure.
300 SOLR WebService support for yaz-client and ZOOM.
302 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
304 --- 4.0.12 2010/08/17
306 Z39.50 facet support. Facet specifications are passed for search in
307 other-information with ASN.1 as defined in facet.asn and OID
308 .10.1000.81.5 . Facets are expressed as an Attribute list as known
309 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
310 3 is limit (number of entries to get in response). yaz-ztest returns
311 dummy facets if a client asks for them.
313 --- 4.0.11 2010/07/09
315 CCL fixes: bug 2895 and bug 3539.
317 GR1-display: add comma in display - was removed by mistake in
320 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
322 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
324 --- 4.0.10 2010/06/18
326 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
327 result set from a connection. The result set will be on its own
328 thereafter; no operations on it will perform retrievals from a target.
329 Only cached copies are returned.
331 ZOOM C:fix case for HTTP servers responding with Connection:close.
332 Ensure that if there is a current task it is resumed (like fetching
333 more records in a result set) . Bug #3484.
335 PQF parser: use odr_atoi for Odr_int (not atoi)
337 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
338 values that contain any non-digits are treated as string attributes
339 (previously decoding only checked for leading character ([0-9]). PQF
340 encoding: attribute string values are not surrounded by double-quotes.
344 New utility for managing threads - thread_create.h.
346 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
347 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
348 but YAZ' implementation do.
350 Fixes for yaz_cond-functions on Windows 7.
352 DLL export more symbols.
354 zoomsh: show record do NOT render opac.
356 Remove *.la files from Debian and RPM packages.
360 Debian package libyaz-dev depends on libgnutls-dev again (was
361 removed in YAZ 4.0.6, but due to Libtool it is still needed
362 even though yaz-config do not list libgnutls libs).
364 ZOOM: Use only one WRBUF for returning string results for
365 ZOOM_resultset. Reduces memory usage for ZOOM in general.
367 ZOOM: ZOOM_connection do not use a shared pointer to
368 ZOOM_resultset after ZOOM_resultset is destructed by
369 user. Reverts to YAZ 4.0.4 behavior.
373 record-conv: fix problem with at least one XSL conversion -
374 due to probably incorrect usage of XML XSL documents.
378 Fix yaz-config for static mode and the use of SSL (gnutls).
382 Forward decl timeval struct in mutex.h and gettimeofday.h.
384 yaz-config: fix 'static' mode linking.
388 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
389 are wrappers for pthreads or Windows. For Windows these are put in
390 a separate DLL: yaz_cond4.
392 libyaz.la (whole source) is compiled with thread. If thread support
393 is enabled enabled, all source of YAZ is compiled with treading support.
394 This allows core utilities such as yaz_log to use thread facilities.
395 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
396 thread utilities. This commit moves mutex utilities (mutex.c) from
397 libyaz_server.la to libyaz.la.
399 yaz-json-parse displays leading text until error.
403 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
404 patch from Giannis Kosmas.
406 SRU: no longer URL encode SRU database. The URL for an SRU server is
407 a URL and such is alreeady encoded - at least when given with leading
408 http:// or https://. This reverts behavior to YAZ 3.0.50.
410 Support for new MARC XML notation TurboMARC which like MARCXML is a
411 complete representation of MARC/ISO2709.. This one, however, is more
412 compact and allows for faster processing with XSLT. TurboMARC can be
413 used in the marcdisp.h API, from the yaz-marcdump utility and from
416 yaz-ztest can be configured - via the database - to perform certain
417 delays when it performs operations search, present and single record
418 fetch. This allows testers to make yaz-ztest act as a real or even slow
419 Z39.50 server. Refer to the yaz-ztest man pages for details.
423 wrbuf_destroy allows NULL WRBUF passed to it.
425 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
427 Add ZOOM_connection_close.
429 No fixed size buffers for ZOOM shell - bug #3257.
431 tstodr: make it work on s390 platform.
433 New icu iterator-functions. The new icu_iter-functions makes it possible
434 to use ICU chains from many threads.
436 yaz-client: better syntax check for show command.
440 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
443 New simple local-file XML include facility which allows file glob-patterns.
444 Refer to yaz/xml_include.h.
446 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
449 ZOOM_record_get supports new parameter "format" which makes it format XML
452 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
453 JSONText in ECMA-262) is JSONValue, not JSONObject.
457 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
458 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
460 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
461 POSIX/Unix builds .so with major version 4.
463 Remove old LOG_-defines from log.h. They have been obsolete and
464 undefined by default for the last 5 years.
466 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
468 GFS: Remove socket (int *fd) from search_rr handler. The socket
469 descriptor ptr is a facility that allowed a search handler to supply
470 a socket which would serve as a callback - when search was complete.
471 This facility has now been in use for years.
473 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
474 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
475 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
476 returns 'const char *' rather than 'char *. The returned string is
477 read-only and should not be modified by applications. COMSTACK cs_close is
478 now a void function - it no longer returns int. No applications check for
479 the value and the implementations has always returned 0.
481 ZOOM: use size_t for scan hit counts and str size. Functions
482 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
483 occ (hit count) and len (string length) are now of type size_t pointer
484 rather than int pointer. This is to be able to represent large hit counts
485 and to also just to use the proper type for string length (strlen result).
487 New JSON parser. Refer to include/yaz/json.h .
489 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
490 Used to be int in some cases. Many wrbuf_-functions used to return an int
491 indicating some length.. These return values were never used. And so they
494 ODR: odr_malloc, odr_total now takes size_t for size.
496 clone_z_type: fix leak; occurred for encoding failures.
498 --- 3.0.52 2009/12/03
500 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
501 bug was introduced in 3.0.51.
503 --- 3.0.51 2009/12/02
505 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
507 tcpip comstack: fix leak for getaddrinfo.
509 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
510 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
511 Decoding of SRU "path" database is performed by private function
512 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
513 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
515 yaz-client: honor base command for SRU. Change when database setting
516 is applied for SRU and ensure it is kept when a connection is reset.
517 Change also the way errors are displayed or SRU (decoding of packages).
519 --- 3.0.50 2009/11/02
521 Add support for extra request / response data for SRU codecs and GFS.
522 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
523 for extra data response buffer and length. For the GFS, both request
524 and response data (XML) is carried in extra_args and extra_response_data
525 for the search handler. Patch by Ko van der Sloot.
527 ZOOM: For queries that cannot be converted to the specified rpnCharset,
528 ZOOM now returns a diagnostic on the client-side ('invalid query' /
529 10010). This fixes bug #2113.
531 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
532 cmdfile included a 'quit' command that would result in a memory violation.
534 --- 3.0.49 2009/10/01
536 Make a number of functions defined in xmlquery.c static. These have
537 never been declared in a public header file (yaz/xmlquery.h) and was
538 made public by mistake.
540 Improve speed of character conversions (iconv utilities). This makes
541 conversions from MARC-8 faster.
543 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
544 unless type desired is "raw". This will prevent type "xml" from
545 returning ISO2709 .. Which obviously can not be XML parsed.
547 Fix memory leak in ZOOM that would occur if option apdulog was used
548 on a re-used connection.
550 Frontend server logs HTTP requests.
552 Frontend server now sends Z39.50 close when it times out (sesssion has
553 been idle for too long). Versions 2.0.30 and earlier also sent close.
554 But due to a mistake this was disabled in all versions after that, i.e.
555 the server would just close the socket immediately.
557 yaz-client emits a better message when receiving an unrecognised
558 userInformationField.
560 Skip zero-length subfields when decoding ISO2709. This rare case happens
561 if a record has two FS characters in a sequence. Without this patch
562 there would be a reference beyond char array in using_code_len fragments
565 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
567 --- 3.0.48 2009/08/28
569 The show command offered by the zoomsh command now takes a 3d optional
570 parameter type which is what is passed to ZOOM_record. If the type
571 argument is omitted, "render" is used.
573 RPN to CQL conv may use USE string attributes (bug #2978).
575 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
577 --- 3.0.47 2009/07/08
579 Function yaz_xml2query allows a diagnostic element in the PQF XML
580 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
581 code and additional info respectively.
583 The BER BOOLEAN is now the integral type Odr_bool which still happens
584 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
585 typedef'd to Odr_int. This is still an integral 'int', but it may be
586 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
587 ASN-1 compiler as well as programs has been updated to use the new types.
589 --- 3.0.46 2009/06/08
591 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
592 only the bibliographic record was rendered. For type=opac, an OPAC
593 record is only returned if it is present.
595 iconv: small fix for encoding of advancegreek.
597 yaz-client: avoid double display of SRU/SRW records (bug #2798).
599 yaz-client: option auto_reconnect=on really reconnects.
601 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
603 server: avoid null ptr ref for for yaz_poll errors.
605 build: fix RPM build for RHEL 5.3.
607 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
609 --- 3.0.45 2009/03/31
611 Fixed bug #2709: TCP connect returns Invalid argument.
613 Fixed compilation for mingw.
615 Honor charset for raw records (ZOOM_record_get).
617 Fixed use of errno for threaded mode that was seen on Solaris 10.
619 Fixed argument passing with blanks in value for Windows Service.
621 Disable YAZ' own log rotate by default (no 1 GB limit).
622 The variable l_max_size which specifies the log file limit is set to 0
623 (DISABLED): This is due to the fact that YAZ is most often deployed using
624 logrotate. Also YAZ can not perform log rotate because of unsufficient
625 permissions (setuid).
627 --- 3.0.44 2009/02/17
629 List supported encodings in man page for yaz-iconv.
631 Fixed missing SSL libs for --libs output
633 Re-established OID record syntax application-xml. Nobody should use it
634 but we don't want to change soname because of this symbol being absent.
636 --- 3.0.42 2009/02/02
638 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
640 Added member named_result_sets for init handler struct for the GFS. This
641 allows a server to disable named result sets.
643 Removed OID record syntax application-xml.
645 Added support for rule-based transliterator for ICU wrapper of YAZ.
647 Fixed bug #1902: yaz-icu XML output.
649 Make YAZ checks Emacs friendly.
651 BITSTRING value shows value. Bug #2346.
653 ISO2709 decoding: skip control characters from indicator data.
655 Omit sort key by default in yaz-icu's output.
657 Allow combined single char options (again) for YAZ' options function.
659 Utility yaz-marcdump got option to display YAZ version (-V).
661 Allow YAZ to use ICU 3.4.
663 Added new ICU test case which illustrates removal of diacritics.
665 --- 3.0.41 2008/12/29
667 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
669 --- 3.0.40 2008/12/29
671 For configure, using option --without-xml2 also disables Libxslt/Libexslt
674 Fixed bug #2352: yaz-marcdump crashes for certain record.
676 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
678 Added support for Danmarc2 to UTF-8 conversion.
680 Added support for ISO5426 to UTF-8 conversion.
682 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
683 implementation version.
685 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
687 --- 3.0.38 2008/11/10
689 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
690 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
692 ZOOM C now interprets databaseName option for ZOOM connection as path
695 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
697 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
699 Dummy Libxml2 types no longer defined in headers of YAZ'.
701 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
704 --- 3.0.36 2008/09/26
706 Various ODR chapter fixes.
708 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
710 Added missing source for Windows compilation, mutex.c.
712 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
714 For SRU connections in ZOOM all records up to "count" are now fetched.
716 Fixed crash in generic frontend server (and yaz-ztest) which occurred
717 in Windows due to bad error handling for Libxml2.
719 Added facility for sending arbitrary records (ASN.1 any) using
720 ZOOM C's Extended service update. Patch by Sam Reynolds.
722 New options for ZOOM C's connection, logapdu which makes ZOOM log
725 --- 3.0.34 2008/06/18
727 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
729 --- 3.0.32 2008/06/12
731 Fixed memory violation that could occur when decoding UTF-8. This bug
732 was only present in 3.0.30 of YAZ.
734 --- 3.0.30 2008/06/06
736 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
737 GNU TLS is used by default (if found).
739 yaz-ztest returns OPAC records if a client asks for OPAC.
741 Improved speed of MARC-8 encoding.
743 Added support for lossy and loss-less MARC-8 encoding.
745 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
747 Added new Windows Service wrapper (sc).
749 yaz-client's itemorder command may now send a file.
751 Fixed yaz-marcdump to allow the use of NS prefix for record element.
753 Added new function yaz_log_xml_errors.
755 Allow (but warn) unknown XML attributes in MARCXML parsing.
757 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
759 The UTF-8 to MARC-8 conversion now uses a different set of characters
760 for Greek symbols. Bug #2120.
762 --- 3.0.26 2008/02/21
764 Added yaz_daemon (daemon.h).
766 Fixed bug #2068: pkg-config trouble
768 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
770 --- 3.0.24 2008/01/28
772 Document --with-xml2 option.
774 Added OPAC XML XSD (etc/opacxml.xsd).
776 Allow glob mask for name attribute in retrieval element for the
777 generic frontend server's retrieval facility.
779 Changed yaz_poll_poll to return yaz_poll_except for all returned events
780 except POLLIN/POLLOUT.
782 Fixed error handling in cs_listen. Bug #2037.
784 --- 3.0.22 2008/01/20
786 Fixed version in yaz/yaz-version.h.
788 Fixed bug #2027: Crash when closing connection.
790 Changed configure so that ICU support is only enabled if only ICU
791 and Libxml2 is available (because the ICU chain is XML based).
793 --- 3.0.20 2008/01/15
795 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
796 is built. Only this DLL depends on the ICU runtime.
798 yaz-ziffy is no longer part of YAZ. It is distributed separately by
799 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
801 Changed license of CCL module to 'Revised BSD'. After consultation with
802 remaining members of the original EUROPAGATE consortium, we are re-issuing
803 the CCL module without a separate license. The software was developed by
804 Index Data as part of a research project. The special license was included
805 to help feed usage information back to the project consortium to support
806 project evaluation. At this time, the project consortium has long-since
807 disbanded, and the majority of the original principals have retired. At the
808 same time, we have significantly modified the software during the following
809 years, to the point where very practically no original code remains. To
810 simplify re-use of the software, we have contacted those members of the
811 consortium who could be reached, and agreed to re-issue the module as a
812 proper part of the YAZ package.
814 Tcl scripts uses /usr/bin/tclsh as preferred shell.
816 CQL closer to being version 1.2 compliant. CQL also allows free-form
817 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
820 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
821 bug could make Extended services handling crash in the ZOOM layer. This
822 bug was only present in YAZ 3.0.18.
824 --- 3.0.18 2007/12/19
826 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
829 yaz-marcdump reads and writes collection wrapped records.
831 Handle OPAC for record conversion module.
833 Fixes for ICU wrapper.
835 Allow ICU libs to be controlled with --with-icu .
837 --- 3.0.16 2007/11/12
839 Added yaz_poll which is a wrapper for select/poll. When poll is available
840 and non-buggy, it is used, by yaz_poll . This allows more than 1024
841 sockets to be in use.
843 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
844 functionality through an XML based configuration (ICU chain). This system
845 is useful for search facilities such as Pazpar2 and Zebra that needs to
846 perform tokenization of indexed material. The ICU code in a separate
847 library libyaz3_icu.a.
849 Added HTTP tunnel facility for COMSTACK, bug #1752.
850 This is a facility that allows a Web proxy, such as squid, to tunnel
851 Z39.50 traffic. This facility is "transparent" to must applications
852 using YAZ. It's enabled by using pseudo transport connect: followed by
853 the proxy address, followed by command, then follwed by he regular
854 "virtual" addresss. For example,
855 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
857 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
859 --- 3.0.14 2007/09/21
861 Fixed bad memory reference in ZOOM_record - cuased by member not being
862 initialized. This was a problem only in YAZ 3.0.12.
864 Fixed bug in conversion from MARC to XML: Non-XML characters in control
865 fields were not removed.
867 Changed the way C code is generated from codetables.xml. Made a MARC-8
868 conversion trie for each characterSet section rather than codeTable.
869 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
870 of codetables.xml from Larry Dixson, LOC. Bug #1464.
872 --- 3.0.12 2007/09/12
874 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
875 from ZOOM_record_error).
877 ZOOM C function ZOOM_record_get returns record schema for type="schema".
879 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
881 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
883 Better SRW-to-Bib-1 diagnostic mapping.
885 ZOOM C and yaz-client announces SRU version 1.2 by default.
887 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
890 Fixed in yaz_sru_decode to allow other version than 1.1.
892 --- 3.0.10 2007/08/22
894 Added support for SRU scan for ZOOM.
896 Added support for the use of the older versions or Extended Service
897 Update in ZOOM. To faciliate this, an option "updateVersion" may be
898 set to the version , 1=first, 2=second, 3=third. The third version is
899 what ZOOM C has used so far. And that, obviously, is the default.
901 Added support for CCL queries in Z39.50 queries sent to the GFS (and
902 therefore in Zebra and in SimpleServer-based applications). The new
903 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
904 qualifier file used to transform incoming CCL queries into Type-1 RPN,
905 which is passed into the back-end search callback function.
907 Added support for HTTP Basic authentication in clients: the SRU/W
908 codec encodes the username/password elements of the PDU structure
909 appropriately, and these may be set using the "user" and "password"
910 options in ZOOM-C applications (the same options that are used for
911 Z39.50 authentication).
915 Fixed bug #1208: SSL appears to be broken in ZOOM.
917 Fixed bug #1206: Libxml2 include path weirdness.
919 Added oid_name_to_dotstring.
921 Allow elementSetName to be specified for ZOOM C record update.
923 Allow waitAction to be specified for ZOOM C based for Extended Services.
925 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
926 syntax OID. Bug introduced in YAZ 3 series.
928 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
932 Fixed bug #1157: yaz-client does not read .yazclientrc from current
933 directory. yaz-client now reads commands from file given by option -f
934 if specified; then tries to read .yazclientrc in current directory.
935 Failing that, it reads .yazclientrc from user's home directory.
937 Added support for correlationInfo Note and ID for Record Update via
940 Added yaz-client command querycharset which specifies character set for
941 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
942 (termListAndStartPoint).
944 Charset ISO5428:1984 is an alias for ISO5428-1984.
946 Implemented a way to perform scan in a result set using Z39.50. This
947 is achieved by attaching the result set name in the characterInfo
948 (type InternationalString) of OtherInformation in the Scan Request PDU.
949 The result set is identified in the otherinformation by the new OID:
950 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
951 This allows for scan in result set and faceted search . Zebra did some
952 of this in the APT term using attribute type 8 and value being result
953 set. Using the OtherInformation approach for this is cleaner and easier
954 to work with in proxies and the like. This facility can be used in
955 yaz-client using new command setscan which takes a result set as first
956 argument, start position (APT) as second.
958 Changed decoding of SRU XML packed records to deal with servers that
959 have recordData with XML data with multiple root nodes. Also make
960 comparison for recordPacking case insensitive. Again, one server
961 returns "XML" where others return "xml".
963 For SRU responses allow Content-Type application/xml as well as text/xml.
967 Fixed bug in character set conversion of BER strings. Bug introduced
972 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
974 For OID class, use oid_class consistently.
976 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
979 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
980 character set for bibliographic information interchange". By Giannis Kosmas.
982 Added documentation on new OID API.
986 Changes to generic frontend server interface: added new member
987 'query_charset' for bend_initrequest structure. A backend init handler
988 should set this member to its native character set for query terms.
989 When defined, the frontend server logic will announce this character set
990 to a client if the negotiationModel bit is set by the client. All server
991 implementors are encouraged to specify this. If a backend server does not
992 specify this a warning is issued using yaz_log(YLOG_WARN,..).
994 Added CCL utility to remove terms (stop words) from resulting RPN
995 tree. This is handled by functions with prefix ccl_stop_words_ .
997 New ZOOM C option, "rpnCharset", which allows client-side conversion of
998 terms in RPN queries.
1000 Clean-up the CCL API. Moved some internal structures from ccl.h to
1001 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1002 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1003 This is replaced by ccl_parser_find_str which takes a string instead.
1005 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1006 libyaz.la is the core of YAZ except the generic frontend server and
1007 does not depend on POSIX threads anymore. libyaz_server.la is the
1008 generic frontend server facilities and uses POSIX thread functionality
1009 if available. The libyaz.la no longer depends on POSIX threads because
1010 the number of global structures is limited. NMEM no longer re-uses blocks
1011 between threads ; it simply free's memory immediately but allocates in
1012 "large" chunks as usual. We don't expect any performance penalties
1013 because of this. The yaz_log system is still using a global log_level so
1014 caution must be taken when modifying it with yaz_log_init_.. +
1015 yaz_log_mask_str. This, however, should not cause any trouble because
1016 these functions are called during initialization of application code
1017 anyway. `yaz-config --libs server` returns libs for server applications;
1018 `yaz-config --libs` returns libs for non-server applications.
1020 New OID database - with public definitions in oid_db.h. Removed old OID
1021 database including the head oid.h and definitions such as enum oid_value
1022 and struct oident. The new OID database uses the same string names as
1023 before but the 'protocol' is gone. There are now only two representations
1024 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1025 converts from string to OID; functions with prefix yaz_oid_to_string
1026 converts the other way.
1028 Change to emit_term() in CQL-to-PQF query translation: when a term has
1029 the /regexp relation modifier, do not process it for leading and
1030 trailing "^" and "*", which have quite different meanings in regular
1033 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1034 write handlers no longer carries a 'last' parameter. This will make
1035 yaz_iconv flush "less" characters. A flush is performed by call to
1036 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1038 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1039 removed, because function yaz_query_to_wrbuf does the same.
1041 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1042 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1044 Deprecated MARC utility functions removed.
1046 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1049 Branch split: YAZ_2_1_55_branch
1051 --- 2.1.54 2007/03/16
1053 Fix to ZOOM-C so that transparent reconnection is properly handled on
1054 connections that are in asynchronous mode.
1056 Fixed compilation on OpenBSD 4.0.
1058 Large strings in GRS-1 records are now properly displayed in yaz-client.
1060 Added character conversion support for "advancegreek"; based on patch from
1063 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1064 sequence is met. Before the error was not set so it would be unknown.
1066 Adjust yaz-marcdump MARC reader so that it skips until record separator
1069 --- 2.1.52 2007/03/07
1071 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1072 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1073 fd_set structure used as a bitmask for the FDs to be selected on.
1075 Using ACX_PTHREAD macro to check for POSIX threads.
1077 Fixed have-vsnprintf check.
1079 --- 2.1.50 2007/02/23
1081 Fixes for configure on BSD. Bug #900.
1083 Added snprintf/vsnprintf wrappers for systems that don't have
1084 limits (heavens forbid).
1086 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1087 created before all previous tasks were completed and removed from the
1088 task queue, the new task could be removed by a mistake.
1090 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1092 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1094 Fixed bug #832: Problem with MARC/charset in yaz-client.
1096 Fixed bug #668: save command line history for yaz-client.
1098 Fixed bug #830: pkg-config support.
1100 --- 2.1.48 2007/01/23
1102 Extended ZOOM result set options with two options that may be read by
1103 a client: resultSetStatus and presentStatus with values as specified for
1105 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1107 Fixed bug #827: Using SSL fails on Debian etch.
1109 Fixed bug #826: Weird looking chars for set of MARC records.
1111 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1112 that is treated as an ItemOrder with itemRequest being an XML document
1113 external. The value of "doc" is the content.
1115 Extended the GFS search facility. New member of bend_search_rr
1116 'estimated_hit_count' signals that hits is known to be an estmate
1117 (higher or lower than real hit count). New member 'partial_resultset'
1118 signals that the search was partial (hit count is lower or equal than
1119 real hit count). For Z39.50, the information is stored in resultSetStatus
1120 member of SearchResponse APDU. For SRU, the information is signalled
1121 via SRU diagnostic 59: "Result set created with valid partial results
1124 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1126 --- 2.1.46 2007/01/13
1128 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1130 Added ZOOM_connection_peek_event.
1132 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1133 the following new functions:
1134 ZOOM_event_nonblock, ZOOM_connection_process,
1135 ZOOM_connection_get_{socket,mask,timeout},
1136 ZOOM_connection_fire_event_{timeout,socket}.
1137 The existing blocking event handler, ZOOM_event, is a wrapper for the
1138 + blocking ZOOM_event_sys_{poll,select}.
1140 Implemented function ccl_xml_config which parses XML version of CCL
1141 configuration (bug #798).
1143 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1145 Added timings utility (yaz/timing.h)
1147 --- 2.1.44 2007/01/03
1149 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1152 Fixed bug #779: Rotation of apdu.log fails.
1154 Fixed for character set conversions:
1155 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1156 Honor G1 set in MARC-8 decoding.
1158 --- 2.1.42 2006/12/17
1160 Fixed bug #775: char conversion does not handle Alternative UTF-8
1163 Implemented function yaz_marc_read_line which parses MARC line format
1164 records. There is a wealth of formats out there. So far, this function
1165 reads line records produced by yaz_marc_write_line.
1167 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1168 more generic and easier to remember(!) options: -i format and -o format
1169 which specifies input format and output format respectively - where
1170 format is one of "marc", "marcxml", "line", "marcxchange".
1172 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1173 does not print anything except warnings for records.
1175 For yaz-marcdump, added support for MARC split into files (-s) with a given
1178 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1179 spec, at http://www.loc.gov/standards/sru/record-update/
1180 This has changed the binary layout of the following structs:
1181 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1182 bend_update_rr . Patch by Ko van der Sloot.
1184 Added GFS utility function bend_assoc_is_alive which returns 1 if
1185 association is still alive (client is connected); 0 otherwise (client
1186 closed connection). This allows busy servers to stop working for
1189 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1190 been a separate piece of software. This version of ziffy has been modified
1191 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1193 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1195 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1196 Client code may now interrogate options such as "init_opt_sort" to
1197 find out whether the server claims to support various options.
1199 --- 2.1.40 2006/11/27
1201 Added utilities yaz_{set,get}_esn to set/get element set name from
1204 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1205 of YAZ and has been so since YAZ 2.1.10.
1207 Implemented ZOOM_record_error which returns error information for
1208 record (surrogate diagnostic).
1210 --- 2.1.38 2006/10/31
1212 Updates for SRU Update by Ko van der Sloot:
1213 1. Changed name from "operation" to "action"
1214 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1215 versions in the code, marked as 'backward compatible'.
1216 3. Added diagnostics for SRU Update.
1218 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1220 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1222 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1224 For GFS, fixed problem with SRU diagnostic 'First record position out of
1225 range' being issued for 0 hits.
1227 zoomtst10 part of Windows Build.
1229 --- 2.1.36 2006/10/13
1231 Implemented yaz_filepath_comp which splits a path into file path
1232 components (required by Zebra 2.0.3+).
1234 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1235 BSD inspired license until now so this should not have any real impact on
1236 anybody. See http://www.opensource.org/licenses/bsd-license.php
1238 Fixed bug #687: Missing log lines.
1240 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1243 Fixed bug #689: SRU diagnostics to be added.
1245 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1246 whether a connection is idle (no more work do do).
1248 --- 2.1.34 2006/10/04
1250 Change type of optval from long to int for invocation of setsockopt with
1251 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1253 Added support for specifying the max log file size for the Generic
1254 Frontend Server. The size is given with option -r.
1256 --- 2.1.32 2006/09/21
1258 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1260 --- 2.1.30 2006/09/17
1262 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1265 Fixed bug in Generic Frontend Server that could cause a server to stop
1266 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1268 For the generic frontend server, the maximum record size is used as maximum
1269 size of incoming packages (SRU + Z39.50). The value until was previously
1270 only used in Z39.50 Init negotiation and, later, in a session controlled
1271 sizes of records returned. This is controlled using -k option. It can be
1272 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1274 --- 2.1.28 2006/09/04
1276 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1279 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1281 New option for yaz-marcdump -lpos=value which allows setting a portion
1282 of MARC header to a certain value.
1284 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1286 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1287 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1289 --- 2.1.26 2006/08/15
1291 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1294 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1296 --- 2.1.24 2006/08/08
1298 Fixed MARC ISO2709 encoding routines to deal with character set
1301 Minor changes to GFS logging. Database included in search request log
1304 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1305 cached/multiple records.
1307 Shared libraries are built by default on Unix+configure.
1309 Changed cql2pqf transformation to use a different evaluation order. The
1310 new order is: always, relation, structure, position, truncation, index
1311 and relationModifier. Old order was: always, relation, relationModifier,
1312 structure, index, position, truncation. Note that the the latter ones
1313 override former ones for identical attributes.. The new scheme means that
1314 it is possible to override any existing attribute with a relationModifier.
1315 And also that it is possible to override everything for the index rule
1316 (except the ones listed in relationModifier). No order is perfect but this
1317 one, we believe, covers more real cases.. The "always" should have been
1318 called "default", since the attributes there can be overridden with all
1321 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1322 compilation phase, but also for yaz-config --cflags output. This allows
1323 us to have public headers with Libxml2 stuff in them . It should also,
1324 eventually, make Libxml2 checks redundant in packages using YAZ, such
1327 --- 2.1.22 2006/06/15
1329 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1330 stored in uri, message and details.. Previously diagnostics were stored
1331 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1332 compatibility.. but he's probably the only one affected, so.
1334 Added support for CCL, compiled on the client side, in ZOOM-C. This
1335 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1336 input; the resulting query objects can be used for for searching with
1337 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1339 YAZ' configure searches for OpenSSL by default.
1341 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1342 SL_CTX_use_certificate_file. See
1343 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1344 for more info. Thanks to Ko van der Sloot.
1346 --- 2.1.20 2006/06/02
1348 Bug #600: SRU GET, POST support for yaz-client. Introduced
1349 command 'sru' which selects method SOAP/GET/POST.
1351 Allow missingValueAction to be specified for the sortspec string -
1352 function yaz_sort_spec. By default, the missing value action is null.
1353 Use ! to specify "abort". Use = followed by stringvalue to specify default
1356 Ensured that Present-handler (if defined) is called in GFS before any call to
1357 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1358 searchRetrieve requests.
1360 Documentation for YAZ is now based on the Docbook XML/XSLT using
1361 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1362 is no longer depending on jade/openjade or docbook-to-man scripts.
1363 PDF is no longer part of the distribution - but can optionally be
1364 made using DSSSL/jadetex or FOP.
1366 Added retrieval handling support in Generic Frontend Server to support
1367 conversion between MARC/XML as well as XSLTtransforms. See
1368 etc/yazgfs.xml for an example.
1370 Added Authentication support to Generic Frontend Server in SRU
1371 mode. Authentication using HTTP Basic is supported, as is the use
1372 of 'x-username' and 'x-password' parameters in the request itself.
1374 Added support for a new character set MARC8s identical to MARC8 except
1375 that it converts combined characters to single Unicode characters in the
1376 Latin-1 range (when possible).
1378 --- 2.1.18 2006/04/24
1380 ASN.1 compiler 0.4: generates brief Doxygen file header for
1381 generated .h/.c files.
1383 Utility yaz_iconv now supports conversion to MARC-8.
1385 New facilities for the MARC module. The reading - and writing of
1386 content are separate methods for the yaz_marc_t handle. The following
1387 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1388 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1389 format). Write functions have prefix yaz_marc_write_.. The existing
1390 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1391 available. Removed support for OAI-MARC and simplexml (not the
1392 simplexml from PHP5).
1394 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1395 to be returned for this connection.
1397 --- 2.1.16 2006/03/31
1399 Allow multiple languages and charsets to be specified with
1400 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1401 negcharset iso-8859-1,utf-8
1403 Translation of proximity nodes from CQL into PQF now works.
1405 Moved to automake 1.8, 1.9.
1407 Added function yaz_log_set_handler which allows a log handler to be
1408 installed. This handler will be called for all log messages. Output
1409 to file is also produced; but that can be disabled by passing NULL
1410 fname to yaz_log_init_file.
1412 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1414 For SRW (including GFS), accept application/soap+xml as content-type
1417 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1418 produces NO stylesheet reference even if a default stylesheet is specified
1421 --- 2.1.14 2006/03/14
1423 Updated Windows package to include yazd.dll + yazd.lib for the
1424 Development component.
1426 If the environment variable YAZ_LOG is set, then it is used as a
1427 string indicating the default level of logging to use if not
1428 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1429 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1430 used as before. So, for example, to omit warnings from YAZ logging,
1431 export YAZ_LOG=-warn
1433 cql_transform() now map structure and other attributes before indexes,
1434 so that index-specific structures and other attributes can override
1435 defaults. So now a combination of mapping specifications such as:
1437 index.dc.date = 1=date-modified 4=5
1438 does the right thing.
1440 cql_transform() now also respects the "always" mapping specification,
1441 which establishes an initial set of attributes to be used for all
1442 terms except where overridden by more specific attributes associated
1443 with the index, relation or modifier.
1445 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1446 which mode to use; one of "post", "get" or "soap" (SRW, default).
1448 Fixes for yaz_iconv routines: changed trie-based character set conversions
1449 to use only non-negative values for bit fields due to Sun's C compiler not
1450 supporting negative values.
1452 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1453 sequences where not read correctly. Fix by Rustam Usmanov.
1455 Updated win/makefile to use options, settings which makes things
1456 compile with VS C 2005.
1458 --- 2.1.12 2006/02/01
1460 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1462 In ZOOM socket code, use select instead of poll on MacOSX.
1464 ZOOM-C now support client-side compilation of CQL into RPN that is
1465 sent to the server, enabling CQL to be used against all Z39.50
1466 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1467 ZOOM_query object, and submit it using ZOOM_connection_search().
1468 The CQL-to-RPN translation uses a configuration file, the name of
1469 which must be specified in the Connection's "cqlfile" option.
1471 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1472 function, which takes as its start-term parameter a ZOOM_query object
1473 (which may have had either CQL or RPN set into it).
1476 --- 2.1.10 2005/11/29
1478 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1479 GFS to support this as well. Backend handler, bend_srw_update, does the
1480 update work. Code contributed by Ko van der Sloot.
1482 Allow retrieval of Search Result-1 information in ZOOM by the use of
1483 options that are attached to a result set. ZOOM documentation updated
1486 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1487 UTF-8 conversion. Patch by Raj Patel.
1489 Added option -m to GFS to control formatting of timestamps in log file.
1491 Added 'exit' as synonym for 'quit' in yaz-client
1493 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1494 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1495 for the new members. Patch by Ko van der Sloot.
1497 Added support for SRU POST. It is supported for content-type
1498 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1500 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1501 Instead make the library libyaz.la multi-threaded. Threading as a whole
1502 can still be disabled by configure option --disable-threads. Previosly,
1503 with older GLIBCs there were problems with MT libs under Apache. This
1504 has now been fixed a long time ago.
1506 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1509 CQL module modified to be case insensitive for relations/indexes/operations.
1511 Fixed bug in CQL transform code: incorrect value relationModifieder
1514 Added 'show all' command for yaz-client which retrieves all results
1517 Added new yaz-client, xmles, which takes a (private) OID and
1518 a document to be sent as an extended service request.
1520 Describe new yaz-client commands wait_response and set_auto_wait.
1522 Increase TCP/IP listener backlog from 3 (which I am guessing was
1523 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1524 that the socket will queue as many incoming connections as it's able
1525 to handle ongoing connections. In other words, it will never now
1526 refuse a connection that it would be able to handle merely because
1527 it's not got around to accepting() enough of the pending connections
1528 yet. This is the behaviour anyway under Linux, where the listen()
1529 argument is ignored; but not under BSD and on systems such as
1530 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1531 YAZ-based servers should now be uniform across operating systems in
1534 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1535 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1536 This allows yaz-marcdump to read large MARC batches (>2 GB).
1538 Modified all YAZ source files - except the source which is auto-generated
1539 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1542 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1543 corresponding to the existing *_setl() function. These allow option
1544 values containing arbitrary valuues.
1546 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1547 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1548 except that it returns an indicator of whether or not the sort
1549 criterion was accepted (0 for OK, -1 for invalid).
1551 --- 2.1.8 2005/06/07
1553 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1554 MARC output rather than returning "new" buffer.
1556 yaz-client warns about unknown init options.
1558 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1560 --- 2.1.6 2005/05/24
1562 Added support for SRW sort in Generic Frontend Server. Patch
1563 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1564 sortKeys - or NULL if none is provided.
1566 Fixed bug #307: It was impossible to specify indefinite/no timeout
1567 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1570 Added support for multiple languages and charsets to be specified in
1571 ZOOM. Each charset/language is separated by a blank. If negotiation is
1572 in effect in init-response, Option
1573 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1574 Code based on patch by Vasiliy Osadchuk.
1576 Fixed bug #306: infinite recursion that occurred when calling
1577 yaz_log_level_init as the first call (before other log level or
1580 Fixed bug in scan handling in front end server: if preferred-Position-In-
1581 Response was non-present, a NULL pointer referece was performed.
1583 --- 2.1.4 2005/04/26
1585 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1586 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1587 now defined for all those error codes. So instead of putting 109 in
1588 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1589 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1591 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1594 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1596 Program yaz-client now exits and produces an error message if multiple
1597 Z39.50 servers are specified on the command line (none or one allowed
1600 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1603 --- 2.1.2 2005/03/16
1605 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1607 Fixed bug #272: Preserve spacing for CCL terms.
1609 --- 2.1.0 2005/03/14
1611 Added support for virtual hosts and multiple backend servers for
1612 the YAZ frontend server. The configution is XML based and
1613 support specificition of CQL to RPN mappings and explain information.
1614 See section "Virtual Hosts" in the YAZ manual.
1616 Extended OPAC display utility. OPAC display utility renders
1617 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1618 to supplement yaz_marc_decode_wrbuf.
1620 Fixed a bug in MARC decoder that could caused it to crash for some
1621 invalid MARC records. More diagnostics and warnings where added in
1622 XML output (warnings, etc are stored in comments).
1624 --- 2.0.34 2005/02/08
1626 Fixes for UNIX domain sockets. Bug #261.
1628 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1630 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1631 Added yaz_marc_subfield_str which defines subfield lead string which is
1632 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1633 yaz_marc_endline_str which defines end of fields string used in
1634 YAZ_MARC_LINE format. Default string is newline.
1636 Experimental support for MarcXChange. This format can be produced
1637 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1638 http://www.bs.dk/standards/MarcXchange.xsd
1640 Added yaz-client commands scansize that sets maximum number of
1641 entries to be returned by scan.
1643 --- 2.0.32 2005/01/11
1645 Added support for SRW scan in yaz-client and Generic Frontend Server.
1647 * Added whereInList member to SRW Scan Term.
1649 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1651 Fixed NMEM system to return aligned blocks on the smallest boundaries
1652 that are suitably aligned for all possible types on the particular
1653 architecture YAZ is being built for.
1655 --- 2.0.30 2005/01/04
1657 Fixed numerious warnings that was issued with newer versions of GCC.
1659 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1660 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1663 Make YAZ Generic Frontend Server slightly faster.
1665 Enhance (and reduce) logging for Generic Frontend Server.
1667 Revert YAZ log system so that it flushes every write operation
1668 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1670 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1671 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1672 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1673 will effectively disable old definitions.
1675 --- 2.0.28 2004/11/09
1677 Added yaz_log_time_format which specifies log format using
1680 Added yaz_log_module_level which returns mask for a module. Value
1681 is non-zero mask a if module is enabled; zero if disabled.
1683 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1684 in include/yaz/cql.h.
1686 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1688 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1690 Fixed bug #172: RPM builds does not enable SSL.
1692 Doxyfile.in part of dist. Doxyfile generated by configure.
1694 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1695 are given and the corresponding component does not exist.
1697 Extend CCL documentation in YAZ reference. Describe r=r.
1699 --- 2.0.26 2004/10/01
1701 Fixed MARC->MARCXML conversion to properly deal with
1702 fields, subfields, indicators having non-ASCII characters.
1704 Fixed MARC->MARCXML conversion so that ASCII control characters
1705 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1708 Added YAZ GFS support for conversion from Z39.50 surrogate
1709 diagnostics to SRW surrogate diagnostics.
1711 Bug fix: YAZ GFS did not return schema in explainResponse.
1713 --- 2.0.25 2004/09/30
1715 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1716 now converts recordSchema to elementSetName as well as schema URI.
1718 Fixed bug in COMSTACK that prevented HTTP request packages from being
1721 --- 2.0.24 2004/09/29
1723 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1724 does not require white-space before and after the dash in a range, e.g.
1725 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1728 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1729 due to new GCC removing "redundant" code.
1731 Added yaz-client commands scanpos and scanstep that sets preferred
1732 position and step-size for scan.
1734 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1736 Added CCL utility ccl_qual_buf which parses one or more CCL
1737 spec lines in a buffer.
1739 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1740 of name and value - ignoring empty lines and comments.
1742 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1744 Added odr_get_element_path which returns current element path for an
1745 ODR handle. This utility is useful in error handling or user-defined
1748 Added ODR_PRINT utility odr_set_stream which is is a more generic
1749 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1750 to a write function and pointer to close function. The close function - if
1751 non-NULL - will be called during odr_destroy.
1753 Fixed bug in CCL parser where truncation char was not removed from
1754 right side when truncation=both was in effect.
1756 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1759 --- 2.0.23 2004/08/11
1761 Fix buffer overrun in CQL parser when dealing with proximity (%).
1763 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1764 to UTF-8/UCS conversion is now only based on codetables.xml.
1766 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1768 --- 2.0.22 2004/08/06
1770 Add support for more "commit changes" in ZOOM (uses Extended Services).
1772 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1775 Yet another small fix for configure of SSL.
1777 --- 2.0.21 2004/05/14
1779 Fix SSL libs for configure when --with-openssl=DIR is given.
1781 --- 2.0.20 2004/05/10
1783 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1785 SSL comstack now uses yaz.pem certificate file on server side
1786 by default. Certificate filename can be configured by calling
1787 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1789 Fix bug regarding multiple calls to ZOOM_connection_connect.
1791 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1793 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1794 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1796 ZOOM now allows inspection of X509 peer certificate for verification.
1797 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1799 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1800 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1801 as "modular" but it simplifies things.
1803 Added cs_get_peer_certificate to that returns peer X509 PEM.
1805 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1806 NULL if SSL is unavailable.
1808 Documentation about MARC decoding tools.
1810 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1812 --- 2.0.19 2004/03/30
1814 Rename CHANGELOG to NEWS to follow GNU style packing.
1816 Fix bug with missing initialization of member in init_diagnostics.
1817 This bug affects threaded version of GFS server.
1819 --- 2.0.18 2004/03/20
1821 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1824 Ensure zlib.dll is packed with Windows install.
1826 --- 2.0.17 2004/03/17
1828 Fix encoding of xsd:string to use text instead of CDATA.
1830 Fix endless loop in CQL parser with unbalanced ".
1832 Use a more compact way to store MARC-8 conversion tables.
1834 --- 2.0.16 2004/03/16 Debian only
1836 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1839 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1844 --- 2.0.15 2004/03/01
1846 Another fix for decoding of XML packed records.
1848 --- 2.0.14 2004/02/25
1850 Fixes for Chunked encoding. White space not ignored after length spec.
1852 Update NS and use default NS for SRW diagnostic elements.
1854 --- 2.0.13 2004/02/23
1856 Implement ZOOM_resultset_cache_reset which resets record cache.
1858 Implement ZOOM_resultset_sort which sorts a result set.
1860 Implement chunked HTTP transfer.
1862 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1864 --- 2.0.12 2004/02/16
1866 Added member 'schema' to bend_explain_rr structure so that backend
1867 can specify explain record identifier. Defaults to Zeerex 2.0.
1869 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1871 --- 2.0.11 2004/02/16
1873 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1876 Added init command for yaz-client which sends "extra" init request.
1878 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1879 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1881 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1883 Make ZOOM error code for "invalid query".
1885 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1887 --- 2.0.10 2004/02/05
1889 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1892 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1894 Added option -p <file> to make Generic Frontend Server to write PID file.
1896 Added option -D to put Generic Frontend Server in background on its own.
1898 Make ZOOM C recognize option "password". If unset, "pass" is used
1899 (for backwards compatibility).
1901 Fixed a bug in Generic Frontend Server that could make it crash if a
1902 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1905 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1906 Must be issued before open, in order to be in effect.
1908 --- 2.0.9-6 2004/01/12 Debian/Windows
1910 Make the SRU server more picky WRT unknown params, etc.
1912 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1914 New YAZ client command, options, that sets Z39.50 options.
1916 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1917 options from a string of tokens (one token for each option bit).
1919 Update SRW diagnostic code messages.
1921 --- 2.0.9-5 2004/01/07 Debian/Windows
1923 Handle user defined stylesheet for SRW/SRU.
1925 --- 2.0.9-4 2004/01/06 Debian/Windows
1927 Fix bug in decoding of Content-Length.
1929 --- 2.0.9-3 2004/01/06 Debian/Windows
1931 Fix a bug with decoding of XML packed records.
1933 --- 2.0.9-2 2004/01/05 Debian only
1935 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1937 Fix bug in SRW/SRU diagnostics decoding.
1939 --- 2.0.9 2004/01/05
1941 Fixed bug in Generic Frontend Server which could drop records exceeding
1942 preferred message size. Reported and fixed by Irina Dijour.
1944 Fixed calculation of package size for structured records in Generic
1945 Frontend Server. Reported and fixed by Irina Dijour.
1947 Fixed namespace for SRW/SRU diagnostics.
1949 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1951 --- 2.0.8 2003/12/22
1953 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1954 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1957 CQL changes to reflect recent changes to the specification:
1958 * Documentation talks about context sets instead of index sets.
1959 * Documentation talks about indexes instead of qualifiers.
1960 * The CQL-to-PQF transformer's configuration file now uses
1961 "index.set.name = <attributes>" instead of the old form
1962 "qualifier.set.name = <attributes>". (Both forms are still
1963 understood but the latter is deprecated.)
1964 * CQL terms with no explicit index specified are now interpreted as
1965 cql.serverChoice instead of srw.serverChoice (which of course
1966 behaves exactly the same.)
1968 --- 2.0.7 2003/12/16
1970 MARC conversion can now generate ISO2709 output in another
1971 character set. yaz-marcdump uses this facility if you invoke it
1974 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1975 functions from there can be used from C++.
1977 --- 2.0.6 2003/12/04
1979 Frontend server now transfers memory from decoded packages to stream
1982 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1983 references to show up.
1985 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1986 the ZOOM Abstract API. The older names for the same options are still
1987 also supported for the benefit of old applications.
1989 ZOOM-C supports "implementationId" and "implementationVersion" options
1990 to go along with "implementationName". These allow the user code to
1991 specify identification strings to be sent to servers.
1992 Add OID for the new ExtLite attribute set.
1994 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1995 as requested/supplid by Ere Maijala <ere@atp.fi>
1997 For generic frontend server, reverse the order of
1998 "toolkit-supplied / application-supplied" strings sent as implementationId,
1999 Name and Version. Also, remove the spaces around the slash. This brings
2000 the GFS in line with the behaviour of ZOOM-C on the client side.
2002 Add function ZOOM_scanset_display_term.
2004 yaz-client shows scan displayTerm if present.
2006 Utility yaz-iconv is now installed by default along with the man page
2009 Extend configure check for OpenSSL to use pkg-config where available (such
2012 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2013 server to specify uid/gid/mask for socket using the format
2014 unix:[user=uid,][group=gid,][umask=mask,]file=path
2015 If file= is omitted the existing format is assumed, e.g.
2017 in which case the mask is 0666 (rw for everybody).
2019 Major restructure of YAZ source. All source in libyaz is in src directory.
2020 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2021 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2023 Added man page for utility yaz-marcdump (used to be called marcdump).
2024 yaz-marcdump is installed by 'make install'.
2026 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2027 of incoming package failed.
2029 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2031 Change prototype of odr_perror: add const to message string.
2033 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2035 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2036 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2037 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2038 DNS lookup. There should not be any compatibility problems with this
2039 assuming that blocking=1 or 0 is used.
2041 Fix bad reference in UNIX comstack in function cs_addrstr.
2043 Fix for compilation on AIX.
2045 The generic front-end server (server/seshigh.c) now supports returning
2046 Init diagnostics to the client in User-information-field, in
2047 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2050 --- 2.0.4 2003/09/04
2052 Allow any CQL relation (not just all,any,exact,scr).
2054 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2055 that features the same UI.
2057 Implemented command update0 in YAZ client which is equivalent to
2058 update but uses old of Ext Update ASN.1.
2060 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2061 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2062 Previously no OID was used for this info.
2064 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2065 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2066 returns 'malformed search term' otherwise.
2068 SortResponse member resultCount now set to NULL in sort handler of
2071 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2074 Add three new utility functions for translating OIDs between various
2075 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2076 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2077 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2078 char *oid_to_dotstring(const int *oid, char *oidbuf);
2079 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2081 Reverted modifications for ES Update definition for z_IU0Update
2082 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2083 is back to YAZ 2.0.2.
2085 String value attributes for CCL parser.
2087 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2088 which their FirstSearch server returns in Init responses, sometimes
2089 carrying useful diagnostic information when Init fails. This has the
2090 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2091 "z39.50/oclcui.asn", where its definition is somewhat different from
2092 what OCLC document on their web-site, as required to interoperate with
2095 Support for anonymous authentication in yaz-client. Use the command
2098 * Fix the OID of the Index Data-local "admin" Extended Service from
2099 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2100 the 1000, which indicates a locally-defined OID, was a mistake.
2102 --- 2.0.3 2003/06/20
2104 Fix CCL directive @case handling so that it affects string match for
2105 both CCL keywords and qualifiers.
2107 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2108 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2109 Decoder has been updated with ASN.1 changes as listed in
2110 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2111 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2112 z_IUUpdate, remains unchanged.
2114 ZOOM_record_get may now return a record in a specific character set.
2115 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2116 "from" is the character set of record as returned by target. "to" is
2117 the character set to be returned. If omitted, "to" is UTF-8.
2119 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2121 New ODR utility, odr_getelement, which returns name of element for
2122 which encoding/decoding failed.
2124 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2125 in cases where a required element was omitted.
2127 Bug fix: some MARC8 sequences were not converted.
2129 New ZOOM option "step" which specifies number of records to be
2130 retrieved in one chunk. Used in conjunction with "start" and "count".
2132 SRW support for yaz-client. Use scheme http: to use it, e.g.
2135 yaz-client no longer does (un)intelligent character set conversions
2136 by default. Can be enabled with charset and marc_charset commands.
2138 xmalloc trace fix for 64-bit systems such as DEC alpha.
2140 Solaris 2.6 compile fix.
2142 New function, cql_strerror() translates SRW error codes, as returned
2143 by cql_transform_error(), into human-readable English strings. Used
2144 in yaz-client diagnostics when appropriate.
2146 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2147 converts it into a type-1 query which is sent to the server. This
2148 makes CQL available for use with all Z-servers, as opposed to the tiny
2149 minority that can handle CQL queries themselves.
2151 --- 2.0.2 2003/04/28
2153 New Debian package layout similar to the Redhat Package layout.
2155 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2156 and search result respectively.
2158 --- 2.0.1 2003/04/25
2160 Redhat package is now several packages: libyaz (runtime libraries),
2161 libyaz-devel (development and documentation, and yaz (utility programs).
2162 Package spec file by Morten Bogeskov.
2164 New member 'schema' in struct bend_fetch_rr which the name of requested
2165 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2166 handler MAY set this to reflect the schema of the returned record.
2168 New member 'display_term' in struct scan_entry. GFS now sets member entries
2169 and allocates scan entries to be filled by user scan handler. In previous
2170 version, entries member was allocated by the scan handler. That still works,
2171 but the GFS will ignore member display_term - assuming it was NOT set by
2172 the handler. The fact that the GFS now allocates the entries both allows
2173 for new members and makes a scan handler easier to write.
2175 Fix CQL lex buffer overflow.
2177 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2178 SRU default recordPacking is string.
2180 SRU protocol support for frontend server.
2182 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2184 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2186 Added scan for the ZOOM shell (zoomsh).
2190 * String Identifers for Schemas (Amendment 5).
2191 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2192 Old definition for schema
2193 Odr_oid *schema; /* OPT */
2198 Z_InternationalString *uri;
2199 #define Z_Schema_oid 1
2200 #define Z_Schema_uri 2
2203 * resultCount parameter to Sort Response (Amendment 1).
2204 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2206 Support for SRW 1.0 over HTTP. This is an optional feature and
2207 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2210 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2211 on the same port. SRW SearchRetrieveRequests are mapped
2212 to bend_init,bend_search,bend_fetch,bend_close.
2214 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2216 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2217 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2219 ZOOM connections are SRW based if schem http is used for hostname
2220 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2221 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2223 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2224 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2225 distance=n, order=true/false, relation=le, prox unit=word. If
2226 n is omitted, distance 1 is used.
2228 Fixed problem with C compiler include path in wrong order.
2230 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2231 on Solaris. Patch from Ko van der Sloot.
2233 New MARC decode API. All new functions operate on a yaz_marc_t
2234 handle. The most important new functions are: yaz_marc_create,
2235 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2236 decode and destroy respectively. Decoder can produce formats
2237 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2238 include/yaz/marcdisp.h.
2240 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2241 to UTF-8, UCS-32, wchar_t or Latin-1.
2243 * Prototypes for yaz_iconv_-functions moved to separate header
2244 include/yaz/yaz-iconv.h.
2246 Make a few private functions 'static' in unix.c. This prevents
2247 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2249 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2250 are set when Init Response is received.
2252 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2253 but returns diagnostic set as well.
2255 New function yaz_strerror which is a portable wrapper for
2256 strerror/strerror_r/GetLastMessage.
2258 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2259 is returned for MARC. If type is "oai", then OAI MARC is returned.
2261 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2264 --- 1.9.2 2002/11/26
2266 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2268 Fix bad race conditions on SIGTERM and terminate gracefully in
2271 Move retrieval (data1) module to Zebra since nobody seems to be
2274 Add GRS-1 render for ZOOM using same format as yaz-client.
2276 --- 1.9.1 2002/10/05
2278 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2280 Fix broken ESpec handling in data1 module.
2282 SGML reader parses comments and makes them part of the data1 tree.
2284 Added several type casts so that YAZ compiles as C++ code.
2286 ZOOM didn't handle PDU encoding failures properly.
2288 Added more Bib-1 diagnostics (approved extensions).
2290 GNU configure: better check for iconv.
2292 More portable use of accept, getpeername. Check for socklen_t. Use
2293 int/size_t if socklen_t is not defined.
2297 PQF parser rejects bad queries - including those with extra
2298 characters in them. PQF parser used to silently ignore that.
2299 Cleaner API for PQF added, which allows you to get detailed
2300 error information for bad queries (see yaz/pquery.h).
2302 Fixed bug in ZOOM_record_get for type "database".
2304 Implemented mini iconv library supporting conversions between
2305 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2307 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2309 --- 1.8.9 2002/08/20
2311 Fixed ZOOM C record cache so that preferredRecordSyntax and
2312 elementSetName is used to check for already fetched records.
2314 --- 1.8.8 2002/08/02
2316 Added three members in bend_initrequest structure to facilitate
2317 character set negotiation.
2319 Fixed a bug in frontend server that could cause indefinite
2320 loops under rare conditions.
2322 Revised character set utilities (charneg.h) so that encoding
2323 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2325 For PQF, directive @term <type> sets term type for Scan/Search.
2326 Here <type> is general, string, numeric, null. The term type
2327 is inherited - just like @attr.
2329 New call odr_set_charset that sets character set conversion for
2330 international-strings on a ODR stream. Prototype is:
2331 int odr_set_charset(ODR o, const char *to, const char *from);
2332 The InternationalString is still represented as C string in YAZ
2333 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2334 won't). On the protocol level, you can use any encoding.
2336 Support for UNIX sockets in ZOOM.
2338 Solaris recv sometimes returns errno == ENOENT. It is treated as
2339 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2341 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2342 both client and server. Code by Morten Bogeskov.
2344 --- 1.8.7 2002/05/22
2346 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2347 that they can be used directly from Visual Basic. You must recompile
2348 your windows APP if you're using ZOOM.
2350 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2351 Commands "lang" and "charset" sets language and character set respectively.
2352 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2353 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2355 Attributes from multiple CCL fields may be OR'ed rather than merged
2356 using directive "@field or". Fields are still merged by default -
2357 equivalent to "@field merge".
2359 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2362 Fixed bug in zget for parameter ExtendedServicesResponse.
2366 --- 1.8.6 2002/03/25
2368 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2370 Client displays USR.1:SearchResult-1 (hits per term).
2372 Additional Search Info for search in Generic Frontend Server.
2374 Fixed CCL parsing of "field=s".
2376 WIN32 installer - using the excellent NSIS software from nullsoft.
2378 Fixed CCL parsing of "field = - <number>".
2380 Added function yaz_marc_decode that decodes MARC for line mode
2381 display or XML (similar to that used by JZKit).
2383 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2384 Z39.50. But ISO/ILL was, however.
2386 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2387 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2389 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2390 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2392 --- 1.8.5 2002/02/03
2394 New YAZ client features: Command completion and new commands:
2395 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2396 Code provided by Jacob Poulsen.
2398 New call oid_trav, that visits all registered OIDs via callback.
2400 Function ZOOM_record_get now returns const char pointer rather than
2401 void pointer. It saves a lot of type casts.
2403 For YAZ client, command "auth" now allows you to set authentication
2404 in IdPass style. It is enabled when three tokens are given - order
2405 is user, group and password.
2407 Fix memory leaks in MARC record handling for ZOOM.
2409 New option for YAZ client, -k <kilobytes> that sets
2410 maximum record size. Similar to -k option for generic frontend
2411 server and yaz-ztest.
2413 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2415 Prefix query parser reports "fail" when bad attribute set is given.
2417 Fix in MARC decoder. Proximity logging. Fix for attribute set
2418 in scan handler for server. Patches by Shigeru Ishida.
2420 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2423 Configure option --with-openssl=<dir> now works when a directory is
2424 specified. Patch provided by Morten Bogeskov.
2426 New option for YAZ client, -u <auth>, that sets authentication.
2428 ZOOM fix: error information was sometimes "missing", since error
2429 was cleared/reset too when it shouldn't.
2431 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2433 --- 1.8.4 2002/01/04
2435 Scan for ZOOM API. New object ZOOM_scanset. New functions
2436 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2437 ZOOM_scanset_destroy.
2439 New ZOOM function, ZOOM_connection_last_event, that returns type
2440 of last event (such as "receive data", "send data", "apdu received",
2443 New ZOOM option, schema, that specifies schema for retrieval.
2445 New CCL feature. Qualifiers can be aliases for one or more
2446 other qualifiers (if more than one is given, OR is used).
2448 ZOOM uses named result sets if target supports it.
2450 Two new YAZ client commands: . (dot, which sources a script of YAZ
2451 client commands), and ! (to execute shell command.). Implemented
2454 Working on Debian packages.
2456 --- 1.8.3 2001/11/19
2458 YAZ client enables named result sets only if target supports it.
2460 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2462 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2463 with key="host" to get same result.
2465 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2466 Function Z3950_resultset_record(s) returns references to records
2467 "owned" by resultset. To become owner use Z3950_record_clone.
2469 Function z_ext_record handles Extended Services. Thanks to
2472 --- 1.8.2 2001/11/12
2474 CCL Parser fix: ignore token comma when dealing with and-lists.
2476 Documentation updates for COMSTACK.
2478 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2479 Changed prototype Z3950_records. For some functions, int parameters
2480 were changed to size_t.
2482 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2485 New MARC decode/display function, marc_display_exl, which properly rejects
2486 non-ISO2709 records. YAZ client uses it.
2488 --- 1.8.1 2001/10/29
2490 Fix bug: local attribute set wasn't set correctly in PQF strings.
2494 * Old Z39.50 codecs no longer supported.
2496 Added ZOOM C binding. See http://zoom.z3950.org/
2498 Renamed states for COMSTACKs to avoid confusion with events.
2500 Implemented cs_look and proper cs_rcvconnect.
2502 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2504 Configure detects POSIX threads on OpenBSD.
2506 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2507 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2509 When error is returned from present handler, non-surrogate diagnostic
2510 is returned in present response (and fetch handler is no longer called).
2512 * Minor adjustments to pquery parser (PQF). Token characters may be
2513 escaped by using backslash (C-style).
2515 PQF parser allows string attribute values to be specified. For @attr,
2516 non-numeric characters after the equal-sign are treated as strings
2517 (e.g. @attr 9=title).
2519 CCL trunction character may be defined (@truncation in file)
2521 * function zget_ExtendedServicesRequest sets waitAction to
2522 waitIfPossible (was wait).
2524 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2527 CCL operator names may be set in field definition files (CCL_bibset).
2528 See ccl/bib1 for an example.
2530 Fixes in ASN.1 compiler for C++ compatibility.
2532 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2533 and "op_or" to avoid conflict with C++.
2535 Fixed problem with GNU readline detection on Redhat 7.0.
2537 Added step-size for Scan backend handler.
2539 Fixed bug that made the frontend server crash when no attribute
2540 set was specified for scan.
2542 Front-end server automatically switches to original working directory
2543 when installed as an NT service. Previously -w had to be specified to
2546 Added extended attributes for retrieval module (data1), so that data1
2547 records carry d1_readXML/SGML attributes. d1_read also supports
2548 null-data rules ( <tag/>)
2550 On UNIX when POSIX threads are available, a separate library libyazthread
2551 is created. Programmers should link with that library and the yaz library
2552 when using threads. The reason for the split was that some applications
2553 on Linux, such as Apache, doesn't work well when using shared objects that
2556 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2557 (or any frontend server) in SSL mode by specifying ssl: followed by
2558 address. Only tested on UNIX.
2560 Added feature for CCL module. Virtual structure s=al or s=ol generates
2561 and-list and or-list respectively instead of phrase search.
2565 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2566 log_mask_str. This was done to avoid name conflicts with other libraries
2567 (such as other PHP extensions).
2569 Added raw OID member for preferred record syntax (request_format_raw)
2570 and returned record syntax (output_format_raw) for backend fetch method.
2572 Config file yaz-config now accepts options so that it returns specific
2573 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2575 Shared library support for UNIX using GNU libtool.
2577 * Modified backend interface. Request/Response struct's replaced by
2578 one read/write C struct. For example bend_fetchrequest and
2579 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2580 Every handler - even search has to be registered in bend_init
2581 handler. This means that the YAZ library no longer refers to
2582 external functions and it makes it possible to make the whole
2583 thing a single DLL/SO.
2585 Added Segment handler for backend server.
2587 Added Zmbol/Zebra administrative functions to YAZ client.
2589 Threaded frontend server on UNIX (when POSIX Threads are available).
2590 Starting the server with option -T enables multi-threading.
2594 Added configure option --enable-comp/disable-comp to control use
2595 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2596 located in sub directory asn.
2598 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2599 in ${exec_prefix}/bin along with the other programs yaz-client and
2602 GNU automake used to maintain makefiles.
2604 Added several OID's.
2606 Changed retrieval module so that we can load records with no abstract
2607 syntax defined. Tagpaths in these records are fully composed of string
2610 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2614 On UNIX, the generated makefile now supports a proper 'make install'.
2615 The prefix can be set via GNU configure to set the install location
2616 (default is /usr/local).
2618 * YAZ programs client and ztest were renamed to yaz-client and
2619 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2620 locations, such as /usr/bin,/usr/local/bin,etc.
2622 * YAZ Header files were moved from include to include/yaz. YAZ Header
2623 files are referred to as include <yaz/log.h> rather than <log.h>.
2624 The YAZ include path (-I ..) is therefore the same as before. Programmers
2625 should update their #include statements or use -Ipath/include/yaz
2626 instead. The main motivation for doing this change is that YAZ header files
2627 can be installed in "standard" locations /usr/include,/usr/local/include
2628 without introducing conflicts, since ALL YAZ header files are stored
2629 in subdirectory yaz (under /usr/include for example).
2631 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2632 rather than project/workspace files. We switched because project files
2633 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2636 Changed name of logging function, logf, to yaz_log, to prevent name
2637 clash with some math-log functions. The YAZ header log.h defines logf
2638 to yaz_log (#define) so there should be no incompatibilities by this
2641 Added bend_start/bend_stop handlers for server. These handler are
2642 called on start/stop of server. For windows they are called whenever
2643 a service is started/stopped.
2645 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2646 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2647 in util/yc.tcl. The auto-generated C code structures are, in a few
2648 cases, incompatible with the old decoders. There are differences in the
2649 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2650 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2651 The preprocessor variable ASN_COMPILED is defined when the compiled
2652 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2653 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2654 wish to use the old encoders/decoders you can specify --disable-yc
2657 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2658 version so that it supports both new - and old version of DB Update
2660 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2661 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2662 change. The name parameter can be set to 0 in which no name is specified
2663 for the construction. The macros odr_implicit and odr_explicit sets name
2664 parameter to zero for the construction involved. New macros
2665 odr_implicit_tag and odr_explicit_tag are similar to the others,
2666 except that a name parameter is added. For programmers' that don't use
2667 ODR they probably only need to change the call to z_APDU and z_External.
2669 Added access control facility by interfacing the TCP wrapper library.
2670 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2671 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2672 name of the daemon and enables the access control as specified in
2673 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2675 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2676 den Dool <H.M.vdnDool@kub.nl>.
2678 Added reference ID parameter to most functions in server API - refer
2679 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2681 Changed name of ccl library to libccl.a (was ccl.a).
2683 Fixed bug in decoder for Explain (Category TargetInfo).
2685 Added support for GNU readline in client. Thanks to Jacob Poulsen
2686 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2688 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2689 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2690 IMPLEMENTATION! This change was made to the development version before
2691 the ZIG decided to retract the amendment. If any users MUST be
2692 compatible with the original Update definition, PLEASE CONTACT US, and
2693 we will include a separate definition corresponding to the old Update
2694 ES. Note that because of the change to the ASN.1 of the
2695 TaskPackageRecordStructure we cannot define a single structure that
2696 will support both versions.
2698 * Added const modifier to buffer parameter for some ODR/BER encoding
2699 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2700 completeWAIS, odr_dumpBER.
2702 Fixed bug in client.c which caused a crash when a scanResponse didn't
2703 contain positionOfTerm.
2705 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2706 * will cause an error in a client if a non-YAZ target sends both a
2707 * list of Scan entries and non-surrogate diagnostics.
2709 Retrieval module enhancements. Tag sets may be typed in the reference
2710 to it. From the .abs-file the "tagset" directive takes a third optional
2711 integer type for the tag set referenced. From a .tag-file the "include"
2712 directive takes a third optional type as well. The old "type" directive
2713 in the tag set itself is still recognized but acts as the default type
2716 Backend interface change. Individual Scan terms returned from bend_scan
2717 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2718 in include/backend.h.
2720 Retrieval module enhancements. Multiple tag sets and attribute sets may
2721 be specified in abstract syntax specs. Revised the error/warning for
2722 logging messages reported by the retrieval module when reading the
2725 Object Identifier system (oid_..) changed. The API is backwards
2726 compatible but the oid-routines now allocates new OID's when needed.
2727 Raw OID's may be specified in oid_getvalbyname.
2729 YAZ now uses GNU configure to generate Makefile(s).
2731 * Minor changes in some of the member names of DeleteResultSetRequest and
2732 DeleteResultSetResponse. See include/proto.h.
2734 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2735 and added member 'languages' in TargetInfo (which was missing).
2737 Changed the way attribute sets are handled in the retrieval
2738 module. These are now cached, just like the abstract syntaxes
2741 Changed YAZ so that it links with compiled ASN.1.
2743 Added Explain-schema definitions and mapping routines. The following
2744 Explain categories have been implemented: AttributeDetails,
2745 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2747 Fixed minor bug in Windows version of Server Library.
2749 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2751 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2753 Added EXTERNAL: UNIverse Resource Report (non-standard).
2755 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2756 ENUMERATED and SET OF.
2758 * Added 'const' to some of the char pointer arguments for the
2759 functions, data1_read_node, data1_getelementbytagname,
2760 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2763 Fixed bug in data1_insert_taggeddata - the last_child member of
2764 parent wasn't initialised.
2766 * Changed data1_read_record and data1_read_node so that the supplied
2767 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2768 doesn't refer to any parts of the "SGML"-buffer.
2770 Fixed bug in server library (Windows version of statserv_remove).
2772 * Changed code so that it compiles as C++. The type definition
2773 of Odr_fun which is a member of Odr_arm was changed. The result is,
2774 that an explicit typecast is needed for the fun pointer when
2775 using Odr_arm - as in:
2776 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2778 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2780 Implemented the new structured date and time definition as approved
2781 by the ZIG. Added schemaId element to the specificTag in Espec-1
2782 (also approved at the last ZIG). Thanks to RVDM.
2784 Added some Object identifiers (RVDM).
2786 Changed the Update Extended Service (RVDM).
2788 Added command "refid" to client which specifies referenceId for
2789 the following requests.
2791 Implemented extended service handling for server. See ztest.c
2792 for an example as well as backend.h. New handlers are registerd
2793 in the Init handler.
2795 * Changed interface for sort in server.
2797 Added new members to statserv_options_block. It allows a server
2798 to read options from another source than just the command line. Thanks
2799 to Charles Woodfield.
2801 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2802 renamed to zboolean. Some C++ compilers complained about the name.
2804 Minor changes to gils.abs. Added index 's' (sort) on title
2805 and date/time-last-modified.
2807 --- 1.4pl2 1998/1/30
2809 Fixed bug in server library regarding inetd mode (-i). This bug
2810 was introduced by release 1.4.
2812 --- 1.4pl1 1998/1/29
2814 Added sort facility in client and backend server interface.
2816 Fixed problem with dependencies in Makefile(s).
2818 Fixed bugs for encoders/decoders of extended services and
2821 Implemented sub-tree feature for schemas. Sub-trees are
2822 referenced in *.abs-files. See explain.abs for an example
2823 of the use of this feature.
2825 Modified bib1.att; local attributes for ANY didn't include
2826 ANY itself (only affects use of the retrieval module).
2828 Fixed bug in plain SGML reader in function data1_read_node:
2829 tags with prefix "var" was incorrectly interpreted as variants.
2831 Added feature "sub-schemas" to enable references to - and definitions
2832 of - group of elements.
2834 * Removed member parent from type data1_element (in data1.h).
2836 Implemented function odr_nullval() that returns the value of
2839 * Removed member num_children from data1_node (in data1.h).
2841 Made NT service interface part of the server library. The
2842 function statserv_main uses the NT service when required and
2843 calls the statserv_start / statserv_close routines.
2845 Routine zget_SearchRequest and zget_PresentRequest fills
2846 resultSetName/Id member with "default" instead of "Default".
2848 Fixed memory leak in server. Request queue member wasn't freed.
2850 Fixed nmem_exit so that memory is freed.
2854 Revised the CCL parser utility to be thread safe.
2856 Added function, oid_ent_to_oid, to replace the function
2857 oid_getoidbyent, which is not thread safe.
2859 * Added nmem_init and nmem_exit to initialize and release
2860 NMEM resources. Function nmem_init should be called once in the
2861 initial thread before NMEM/ODR is used. statserv.c and client.c
2862 have been changed accordingly. The change was necessary to make
2863 NMEM thread safe. The NMEM memory pool is shared amongst threads
2864 in a process. Unix-based applications will still work fine without
2867 Added NT Services interface for the the Z39.50 (statserv) Server.
2868 Refer to the ztest.c source on the usage.
2870 Windows 95/NT port using MSVC5.0. Project files are included in the
2873 * Defined new 'global' handle for the retrieval (data1) system. The
2874 new handled, data1_handle, describes the state of the data1 system.
2875 This handle is passed as first argument to virtually all
2876 data1 related routines. The functions data1_create and data1_destroy
2877 creates and destroys a data1 handle respectively.
2879 Added ODR encode stream member to all backend request structures
2880 init, search, scan etc. This stream should be used to allocate all
2881 memory used for the response when thread safe operation is needed.
2883 Changed the comstack utility, cs_addstr, to be thread safe. The
2884 returned hostname string returned by the function is now part the
2887 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2888 function. The cs_straddr takes a COMSTACK handle as argument, so this
2889 function must be used after cs_create and before bind/connect.
2890 This function is thread safe.
2892 Moved test server to 'ztest' directory - generic server code still
2893 in 'server' directory.
2895 Made prefix query (pquery.c) utility thread safe.
2897 Added new function modifier YAZ_EXPORT to 'export' public DLL
2898 functions when using windows (see include/yconfig.h).
2900 Added definitions to the OID database (util/oid.c) (RVDM).
2902 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2904 Added call to ccl_rpn_delete in client program.
2906 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2907 release of RPN structure.
2909 Added support for C++, headers uses extern "C" for public definitions.
2910 With input from RVDM.
2912 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2913 Thanks to Ronald van der Meer (RVDM).
2915 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2917 Added support for private extensions to the OID database
2918 (oid_setprivateoids()). Thanks to RVDM.
2920 Added optional, physical ANY (key replication)
2922 Fixed null-reference problem in GRS-1 output filter.
2924 Proximity operator added to Prefix Query Format (PQF).
2926 In test client command "base" accepts multiple databases.
2928 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2932 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2934 Smallish bug-fixes in the new encoders/decoders (explain).
2936 Bug fixed in DeleteRequest.
2938 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2940 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2942 Added SOIF syntax (using private OID for now) to retrieval module and client.
2944 Added Update extended service.
2946 Added SearchResult-1 additional info structure.
2948 Added optional CCL (ISO8777) interpreter as separate module. Available
2951 --- 1.2 1996/6/10 (1st anniversary release)
2953 Added Summary record syntax. Lightly tested.
2955 Added OPAC record syntax. Untested.
2957 Added ResourceReport service encoders/decoders. Untested.
2959 Fixed bug in z_Unit - wrong tagging on unitSystem.
2961 Fixed bug in the DiagRecs decoder.
2963 Added options for max PDU size and session timeout to frontend-server.
2965 Added documentation of query-language parsers and other supporting utilities.
2967 [frontend-server] Added Attribute set to the bend_scanrequest API.
2969 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2970 surrogate diagnostics were generated.
2972 [retrieval] Allow multiple local values for attribute.
2974 [retrieval] Allow multiple attributes per element in .abs files. index type.
2976 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2978 --- 1.1pl2 1996/4/10
2980 Minor changes, mostly specific to Zebra's requirements (retrieval)
2984 Repaired bug in frontend server when running multiple listening
2985 endpoints in dynamic mode.
2987 z_External() now won't break if a known, ASN.1 value comes encapsulated
2988 in an octet-string. The value will pass through unmodified in an Odr_oct.
2990 Added a bit of code to the demo client to decode & display
2991 ASN.1-structured records represented in the octet-aligned branch of
2992 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2994 Added z_ext_getentbyref() to the ASN module. Doc updated.
2996 * Completed the SCAN definition in the ASN module. This may break SCAN
2997 code based on older YAZ-versions at compile-time. The fix is easy -
3000 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3001 under the SCAN definition. Remember to initialize this, server-people.
3003 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3004 that this does not extend to ODR and ASN.
3006 Comstack allows insertion of established socket (primarily for
3007 inetd-operation of servers). Doc updated.
3009 Front-end server can now start from the inetd in TCP mode. Doc
3012 --- 1.0pl4 1996/1/24
3016 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3017 the rank and record number.
3019 Adjustments to the frontend server.
3021 Fixed diagnostic BER dumper. It ignored the file argument.
3025 Various changes to retrieval module.
3027 Changed the union discriminators of the protocol files from enums to
3028 ints paired with #defines.
3030 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3033 *Changed operator in the RPN structure to 'roperator', again to avoid a
3036 Fixed problems in Explain decoders/encoders.
3038 --- 1.0pl2 1995/12/6
3040 Memory bug in log module fixed.
3042 --- 1.0pl1 1995/12/5
3044 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3046 Bug in Explain DatabaseInfo module fixed.
3048 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3052 The shift to v1.0 signals that we now consider the *core* functionality
3053 of YAZ reasonably stable (the core being more or less equivalent to
3054 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3055 tested (Explain not at all - though that will happen soonish).
3057 Minor changes to code to support Windows port.
3059 Various minor changes after we're getting to use GRS-1 & co. more.
3061 Added Espec-1 format.
3063 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3064 of the protocol and it cannot be selected when encoding (maps into 'string'
3065 when decoding). Needed to talk to some servers.
3067 Demo client can request simple element set names.
3069 Added Diagnostic Format encoders/decoders.
3071 Added simple Close handling to frontend server (no hooks for resource
3072 reporting yet), and demonstration client.
3074 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3076 --- 1.0b3 1995/08/24
3078 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3079 handled incorrectly when records were requested in the searchResponse. This
3080 will only affect you if you use the frontend-server.
3082 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3083 Test-client will ask for and print GRS1. Ztest will return dummy records
3086 Added Explain encoders/decoders to the service-level API. Untested.
3088 Added Extended Services: Item Order encoders and decoders to the Service-
3089 level API. Untested. We could use a recent copy of the pertinent bits
3090 of the ILL protocol to add those bits.
3092 Added diagnostic format 1 encoders/decoders to the service-level API.
3095 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3096 odr_cons.c, which causes a more correct output.
3098 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3099 was always set to 0 when no records were requested in the searchRequest.
3101 * Added better external-handling. This shouldn't harm old code that
3102 *encodes* externals. It can break code that looks for a
3103 'single-ASN1-type' representation, since those types that are known
3104 are now decoded immediately. Look at the SUTRS sample code in
3105 seshigh.c and client.c. Documentation updated.
3107 Handling of structured records in bend_fetchresponse. Length -1 marks
3108 structured record, type is deduced from format field.
3110 --- 1.0b2 1995/06/27
3111 Fairly quick maintenance release to add SUTRS support.
3113 Fixed handling of SUTRS records in the demonstration client.
3115 * Added format field to the bend_fetchrequest and bend_fetchresponce
3116 structures of the backend API (frontend server). When the record is
