1 Add support for Solr spell-checking/suggestions through ZOOM.
2 If a Solr target has been configured correctly for spelling-checking
3 and suggestions, these will now be returned on the ResultSet option
4 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
8 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
9 with a flag whether to substitute escape sequences or not.
13 Fix nmem_strsplit_escape to substitute escape char properly.
15 New option for zoomsh -e , which makes it abort on first error and
16 return process exit code to indicate success/failure.
18 YAZ options utility supports special option -- which makes all it treat
19 all following arguments as non-options.
23 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
24 searched if absolute filename is given.
26 Fix conv_xslt() error-reporting when stylesheet is not found.
27 (The value of fullpath is meaningless in this situation.)
31 Fix problem in CQL sort node creation: un-initialized memory.
33 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
34 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
35 CQL sortby depending on whether Type-1 or CQL is actually sent to the
38 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
39 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
41 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
42 will make it possible to use both single-character mask (#) and wildcard (?)
43 in CCL . Throw diagnostic for left truncation because that is not supported
48 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
49 cases using escapes (\-sequences) and masking.
51 PQF parse fix: A trailing backslash followed by end-of-string (\0)
52 would result in a read one byte beyond string.
54 rpn2ccl may use Z39.50 masking for terms (t=z).
56 ICU check fix. Don't include library -lCrun on Solaris, unless present.
58 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
59 not --cppflags (which seeems like an error in icu-config).
61 -- 4.2.12 2011/08/27 RPM package only
63 cql2ccl: fix conversion of terms: operator characters were not
66 -- 4.2.11 2011/08/25 RPM package only
68 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
69 CCL parser will map both # and ? to their regular expression
70 quivalents (. and .*).
72 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
73 of reserved CQL characters.
75 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
76 is, so that they are passed through.
80 ZOOM SRU mode: more aggressive re-connect.
82 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
83 made available as a utility function, declared in <yaz/logrpn.h>
85 rpn2cql_structure() supports proximity nodes (except that the Type-1
86 proximity node's "exclusion" binary is ignored, as there is no way to
87 express that in CQL). Fixes bug #4564.
91 Fix SEGV that could occur if set command of zoomsh was given without
94 Fix SEGV that could occur if unsupported transport was given for
95 COMSTACK - say https (when SSL was unavailable).
97 Build yaz-url on Windows too.
101 New utility to get web content. Header is url.h. A command line tool
102 yaz-url is part of the distribution and packages.
104 Fixes for SSL COMSTACK (when gnutls is in use).
106 New functions yaz_base64{encode,decode}. Header is base64.h.
110 ZOOM C includes HTTP response buffer as additional info if it fails
111 to decode the SRU response.
113 Make wrbuf_json_puts available.
117 zoom: throw diagnostic for invalid value for option "sru". Before a
118 bad SRU request was sent.
120 Adding new utility wrbuf_vp_puts.
122 Add cclxmlconfig.obj to win/makefile. It was missing completely.
126 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
127 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
128 redirect was used at the same time.
130 MARC line mode decoding: be less picky about length given - first
131 5 digits of header that is.
133 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
135 Changes to decoding of SRU records: a record with recordPacking=xml is
136 modified with a new root element <yaz_record> if the recordData contains
137 multiple children elements. This is to make the record XML parseable
140 RPN to SOLR conversion: encode special characters.
142 Generic Frontend Server: fix uinitialized member, stepSize.
146 Fix a bug in SRU decoding of records.. The database records stored
147 had un-initialized memory, but it would only be seen with yaz_record_render
148 and type_spec="ext" .
150 Fix a bug in ccl_qual_dup introduced in 4.2.3.
154 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
158 Add new utilities to convert from CQL to CCL . These utilities have
159 prefix cql_to_ccl defined in cql.h.
161 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
162 lead to memory heap corruptions when ICU utilities were in use.
166 Make compilation work without Libxml2.
168 yaz-client: remove redundant blanks in display of searchResult-1 term
173 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
174 resulting CQL node (tree) in a new node CQL_NODE_SORT.
176 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
177 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
178 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
179 Note that the CQL sortby spec is only converted when the GFS is already
180 converting from CQL to RPN (cql2rpn element).
182 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
183 specify whether to collapse delimitors or not. The existing nmem_strsplit
184 do collapse (collapse parameter = 1).
186 Windows installer: For NSIS, set InstallDir depending on x86/x64.
188 Rename internal func yaz_use_attribute_create. While non-static, this
189 function is not declared in a public header.
193 Add -lCrun when linking with ICU on Solaris.
195 More quicks character set conversions for OPAC records.
199 fix problem with record_render: records were converted (character set
200 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
204 SRU: add methods for handling DADS SRU-proxy facets.
206 Separate OPAC record character set for ZOOM_record. yaz_record_render
207 allows a character set given as charset=from/opacfrom,to where 'from' is
208 the character set of a bibliographic record, 'opacfrom' is character set
209 of OPAC record and 'to' is the target character set.
213 yaz-client: show may XML format records. Command show followed by 'format'
214 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
217 src/stemmer.c: Avoid using unnamed union. It is not supported by some
220 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
223 Update yaz.spec to operate on both SLES11 / Centos 5.5.
225 RPM: Release includes 'indexdata' name. Use indexdata in release name so
226 this package can be distinguished from other vendors.
228 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
229 as determined by configure
231 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
233 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
234 returns no error and no record, the present request is considered
235 partial (only a subset of the records could be returned by backend), and
236 so it is appropriate to set Present Status to partial-4.
240 Move yaz-config man pages to section 1.
242 More documentation about SOLR.
244 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
245 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
246 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
247 peers on some Linux systems. However, in general that does not work
248 so YAZ can not rely on that to work. Debian changed behavior in this
249 respect from Debian lenny to Debian squeeze (still testing as of Oct
251 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
253 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
257 Fix yaz-config output: echo_source not set correctly by configure.
261 SOLR WebService support for yaz-client and ZOOM.
263 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
265 --- 4.0.12 2010/08/17
267 Z39.50 facet support. Facet specifications are passed for search in
268 other-information with ASN.1 as defined in facet.asn and OID
269 .10.1000.81.5 . Facets are expressed as an Attribute list as known
270 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
271 3 is limit (number of entries to get in response). yaz-ztest returns
272 dummy facets if a client asks for them.
274 --- 4.0.11 2010/07/09
276 CCL fixes: bug 2895 and bug 3539.
278 GR1-display: add comma in display - was removed by mistake in
281 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
283 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
285 --- 4.0.10 2010/06/18
287 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
288 result set from a connection. The result set will be on its own
289 thereafter; no operations on it will perform retrievals from a target.
290 Only cached copies are returned.
292 ZOOM C:fix case for HTTP servers responding with Connection:close.
293 Ensure that if there is a current task it is resumed (like fetching
294 more records in a result set) . Bug #3484.
296 PQF parser: use odr_atoi for Odr_int (not atoi)
298 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
299 values that contain any non-digits are treated as string attributes
300 (previously decoding only checked for leading character ([0-9]). PQF
301 encoding: attribute string values are not surrounded by double-quotes.
305 New utility for managing threads - thread_create.h.
307 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
308 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
309 but YAZ' implementation do.
311 Fixes for yaz_cond-functions on Windows 7.
313 DLL export more symbols.
315 zoomsh: show record do NOT render opac.
317 Remove *.la files from Debian and RPM packages.
321 Debian package libyaz-dev depends on libgnutls-dev again (was
322 removed in YAZ 4.0.6, but due to Libtool it is still needed
323 even though yaz-config do not list libgnutls libs).
325 ZOOM: Use only one WRBUF for returning string results for
326 ZOOM_resultset. Reduces memory usage for ZOOM in general.
328 ZOOM: ZOOM_connection do not use a shared pointer to
329 ZOOM_resultset after ZOOM_resultset is destructed by
330 user. Reverts to YAZ 4.0.4 behavior.
334 record-conv: fix problem with at least one XSL conversion -
335 due to probably incorrect usage of XML XSL documents.
339 Fix yaz-config for static mode and the use of SSL (gnutls).
343 Forward decl timeval struct in mutex.h and gettimeofday.h.
345 yaz-config: fix 'static' mode linking.
349 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
350 are wrappers for pthreads or Windows. For Windows these are put in
351 a separate DLL: yaz_cond4.
353 libyaz.la (whole source) is compiled with thread. If thread support
354 is enabled enabled, all source of YAZ is compiled with treading support.
355 This allows core utilities such as yaz_log to use thread facilities.
356 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
357 thread utilities. This commit moves mutex utilities (mutex.c) from
358 libyaz_server.la to libyaz.la.
360 yaz-json-parse displays leading text until error.
364 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
365 patch from Giannis Kosmas.
367 SRU: no longer URL encode SRU database. The URL for an SRU server is
368 a URL and such is alreeady encoded - at least when given with leading
369 http:// or https://. This reverts behavior to YAZ 3.0.50.
371 Support for new MARC XML notation TurboMARC which like MARCXML is a
372 complete representation of MARC/ISO2709.. This one, however, is more
373 compact and allows for faster processing with XSLT. TurboMARC can be
374 used in the marcdisp.h API, from the yaz-marcdump utility and from
377 yaz-ztest can be configured - via the database - to perform certain
378 delays when it performs operations search, present and single record
379 fetch. This allows testers to make yaz-ztest act as a real or even slow
380 Z39.50 server. Refer to the yaz-ztest man pages for details.
384 wrbuf_destroy allows NULL WRBUF passed to it.
386 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
388 Add ZOOM_connection_close.
390 No fixed size buffers for ZOOM shell - bug #3257.
392 tstodr: make it work on s390 platform.
394 New icu iterator-functions. The new icu_iter-functions makes it possible
395 to use ICU chains from many threads.
397 yaz-client: better syntax check for show command.
401 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
404 New simple local-file XML include facility which allows file glob-patterns.
405 Refer to yaz/xml_include.h.
407 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
410 ZOOM_record_get supports new parameter "format" which makes it format XML
413 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
414 JSONText in ECMA-262) is JSONValue, not JSONObject.
418 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
419 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
421 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
422 POSIX/Unix builds .so with major version 4.
424 Remove old LOG_-defines from log.h. They have been obsolete and
425 undefined by default for the last 5 years.
427 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
429 GFS: Remove socket (int *fd) from search_rr handler. The socket
430 descriptor ptr is a facility that allowed a search handler to supply
431 a socket which would serve as a callback - when search was complete.
432 This facility has now been in use for years.
434 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
435 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
436 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
437 returns 'const char *' rather than 'char *. The returned string is
438 read-only and should not be modified by applications. COMSTACK cs_close is
439 now a void function - it no longer returns int. No applications check for
440 the value and the implementations has always returned 0.
442 ZOOM: use size_t for scan hit counts and str size. Functions
443 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
444 occ (hit count) and len (string length) are now of type size_t pointer
445 rather than int pointer. This is to be able to represent large hit counts
446 and to also just to use the proper type for string length (strlen result).
448 New JSON parser. Refer to include/yaz/json.h .
450 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
451 Used to be int in some cases. Many wrbuf_-functions used to return an int
452 indicating some length.. These return values were never used. And so they
455 ODR: odr_malloc, odr_total now takes size_t for size.
457 clone_z_type: fix leak; occurred for encoding failures.
459 --- 3.0.52 2009/12/03
461 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
462 bug was introduced in 3.0.51.
464 --- 3.0.51 2009/12/02
466 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
468 tcpip comstack: fix leak for getaddrinfo.
470 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
471 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
472 Decoding of SRU "path" database is performed by private function
473 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
474 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
476 yaz-client: honor base command for SRU. Change when database setting
477 is applied for SRU and ensure it is kept when a connection is reset.
478 Change also the way errors are displayed or SRU (decoding of packages).
480 --- 3.0.50 2009/11/02
482 Add support for extra request / response data for SRU codecs and GFS.
483 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
484 for extra data response buffer and length. For the GFS, both request
485 and response data (XML) is carried in extra_args and extra_response_data
486 for the search handler. Patch by Ko van der Sloot.
488 ZOOM: For queries that cannot be converted to the specified rpnCharset,
489 ZOOM now returns a diagnostic on the client-side ('invalid query' /
490 10010). This fixes bug #2113.
492 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
493 cmdfile included a 'quit' command that would result in a memory violation.
495 --- 3.0.49 2009/10/01
497 Make a number of functions defined in xmlquery.c static. These have
498 never been declared in a public header file (yaz/xmlquery.h) and was
499 made public by mistake.
501 Improve speed of character conversions (iconv utilities). This makes
502 conversions from MARC-8 faster.
504 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
505 unless type desired is "raw". This will prevent type "xml" from
506 returning ISO2709 .. Which obviously can not be XML parsed.
508 Fix memory leak in ZOOM that would occur if option apdulog was used
509 on a re-used connection.
511 Frontend server logs HTTP requests.
513 Frontend server now sends Z39.50 close when it times out (sesssion has
514 been idle for too long). Versions 2.0.30 and earlier also sent close.
515 But due to a mistake this was disabled in all versions after that, i.e.
516 the server would just close the socket immediately.
518 yaz-client emits a better message when receiving an unrecognised
519 userInformationField.
521 Skip zero-length subfields when decoding ISO2709. This rare case happens
522 if a record has two FS characters in a sequence. Without this patch
523 there would be a reference beyond char array in using_code_len fragments
526 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
528 --- 3.0.48 2009/08/28
530 The show command offered by the zoomsh command now takes a 3d optional
531 parameter type which is what is passed to ZOOM_record. If the type
532 argument is omitted, "render" is used.
534 RPN to CQL conv may use USE string attributes (bug #2978).
536 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
538 --- 3.0.47 2009/07/08
540 Function yaz_xml2query allows a diagnostic element in the PQF XML
541 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
542 code and additional info respectively.
544 The BER BOOLEAN is now the integral type Odr_bool which still happens
545 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
546 typedef'd to Odr_int. This is still an integral 'int', but it may be
547 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
548 ASN-1 compiler as well as programs has been updated to use the new types.
550 --- 3.0.46 2009/06/08
552 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
553 only the bibliographic record was rendered. For type=opac, an OPAC
554 record is only returned if it is present.
556 iconv: small fix for encoding of advancegreek.
558 yaz-client: avoid double display of SRU/SRW records (bug #2798).
560 yaz-client: option auto_reconnect=on really reconnects.
562 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
564 server: avoid null ptr ref for for yaz_poll errors.
566 build: fix RPM build for RHEL 5.3.
568 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
570 --- 3.0.45 2009/03/31
572 Fixed bug #2709: TCP connect returns Invalid argument.
574 Fixed compilation for mingw.
576 Honor charset for raw records (ZOOM_record_get).
578 Fixed use of errno for threaded mode that was seen on Solaris 10.
580 Fixed argument passing with blanks in value for Windows Service.
582 Disable YAZ' own log rotate by default (no 1 GB limit).
583 The variable l_max_size which specifies the log file limit is set to 0
584 (DISABLED): This is due to the fact that YAZ is most often deployed using
585 logrotate. Also YAZ can not perform log rotate because of unsufficient
586 permissions (setuid).
588 --- 3.0.44 2009/02/17
590 List supported encodings in man page for yaz-iconv.
592 Fixed missing SSL libs for --libs output
594 Re-established OID record syntax application-xml. Nobody should use it
595 but we don't want to change soname because of this symbol being absent.
597 --- 3.0.42 2009/02/02
599 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
601 Added member named_result_sets for init handler struct for the GFS. This
602 allows a server to disable named result sets.
604 Removed OID record syntax application-xml.
606 Added support for rule-based transliterator for ICU wrapper of YAZ.
608 Fixed bug #1902: yaz-icu XML output.
610 Make YAZ checks Emacs friendly.
612 BITSTRING value shows value. Bug #2346.
614 ISO2709 decoding: skip control characters from indicator data.
616 Omit sort key by default in yaz-icu's output.
618 Allow combined single char options (again) for YAZ' options function.
620 Utility yaz-marcdump got option to display YAZ version (-V).
622 Allow YAZ to use ICU 3.4.
624 Added new ICU test case which illustrates removal of diacritics.
626 --- 3.0.41 2008/12/29
628 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
630 --- 3.0.40 2008/12/29
632 For configure, using option --without-xml2 also disables Libxslt/Libexslt
635 Fixed bug #2352: yaz-marcdump crashes for certain record.
637 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
639 Added support for Danmarc2 to UTF-8 conversion.
641 Added support for ISO5426 to UTF-8 conversion.
643 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
644 implementation version.
646 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
648 --- 3.0.38 2008/11/10
650 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
651 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
653 ZOOM C now interprets databaseName option for ZOOM connection as path
656 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
658 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
660 Dummy Libxml2 types no longer defined in headers of YAZ'.
662 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
665 --- 3.0.36 2008/09/26
667 Various ODR chapter fixes.
669 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
671 Added missing source for Windows compilation, mutex.c.
673 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
675 For SRU connections in ZOOM all records up to "count" are now fetched.
677 Fixed crash in generic frontend server (and yaz-ztest) which occurred
678 in Windows due to bad error handling for Libxml2.
680 Added facility for sending arbitrary records (ASN.1 any) using
681 ZOOM C's Extended service update. Patch by Sam Reynolds.
683 New options for ZOOM C's connection, logapdu which makes ZOOM log
686 --- 3.0.34 2008/06/18
688 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
690 --- 3.0.32 2008/06/12
692 Fixed memory violation that could occur when decoding UTF-8. This bug
693 was only present in 3.0.30 of YAZ.
695 --- 3.0.30 2008/06/06
697 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
698 GNU TLS is used by default (if found).
700 yaz-ztest returns OPAC records if a client asks for OPAC.
702 Improved speed of MARC-8 encoding.
704 Added support for lossy and loss-less MARC-8 encoding.
706 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
708 Added new Windows Service wrapper (sc).
710 yaz-client's itemorder command may now send a file.
712 Fixed yaz-marcdump to allow the use of NS prefix for record element.
714 Added new function yaz_log_xml_errors.
716 Allow (but warn) unknown XML attributes in MARCXML parsing.
718 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
720 The UTF-8 to MARC-8 conversion now uses a different set of characters
721 for Greek symbols. Bug #2120.
723 --- 3.0.26 2008/02/21
725 Added yaz_daemon (daemon.h).
727 Fixed bug #2068: pkg-config trouble
729 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
731 --- 3.0.24 2008/01/28
733 Document --with-xml2 option.
735 Added OPAC XML XSD (etc/opacxml.xsd).
737 Allow glob mask for name attribute in retrieval element for the
738 generic frontend server's retrieval facility.
740 Changed yaz_poll_poll to return yaz_poll_except for all returned events
741 except POLLIN/POLLOUT.
743 Fixed error handling in cs_listen. Bug #2037.
745 --- 3.0.22 2008/01/20
747 Fixed version in yaz/yaz-version.h.
749 Fixed bug #2027: Crash when closing connection.
751 Changed configure so that ICU support is only enabled if only ICU
752 and Libxml2 is available (because the ICU chain is XML based).
754 --- 3.0.20 2008/01/15
756 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
757 is built. Only this DLL depends on the ICU runtime.
759 yaz-ziffy is no longer part of YAZ. It is distributed separately by
760 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
762 Changed license of CCL module to 'Revised BSD'. After consultation with
763 remaining members of the original EUROPAGATE consortium, we are re-issuing
764 the CCL module without a separate license. The software was developed by
765 Index Data as part of a research project. The special license was included
766 to help feed usage information back to the project consortium to support
767 project evaluation. At this time, the project consortium has long-since
768 disbanded, and the majority of the original principals have retired. At the
769 same time, we have significantly modified the software during the following
770 years, to the point where very practically no original code remains. To
771 simplify re-use of the software, we have contacted those members of the
772 consortium who could be reached, and agreed to re-issue the module as a
773 proper part of the YAZ package.
775 Tcl scripts uses /usr/bin/tclsh as preferred shell.
777 CQL closer to being version 1.2 compliant. CQL also allows free-form
778 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
781 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
782 bug could make Extended services handling crash in the ZOOM layer. This
783 bug was only present in YAZ 3.0.18.
785 --- 3.0.18 2007/12/19
787 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
790 yaz-marcdump reads and writes collection wrapped records.
792 Handle OPAC for record conversion module.
794 Fixes for ICU wrapper.
796 Allow ICU libs to be controlled with --with-icu .
798 --- 3.0.16 2007/11/12
800 Added yaz_poll which is a wrapper for select/poll. When poll is available
801 and non-buggy, it is used, by yaz_poll . This allows more than 1024
802 sockets to be in use.
804 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
805 functionality through an XML based configuration (ICU chain). This system
806 is useful for search facilities such as Pazpar2 and Zebra that needs to
807 perform tokenization of indexed material. The ICU code in a separate
808 library libyaz3_icu.a.
810 Added HTTP tunnel facility for COMSTACK, bug #1752.
811 This is a facility that allows a Web proxy, such as squid, to tunnel
812 Z39.50 traffic. This facility is "transparent" to must applications
813 using YAZ. It's enabled by using pseudo transport connect: followed by
814 the proxy address, followed by command, then follwed by he regular
815 "virtual" addresss. For example,
816 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
818 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
820 --- 3.0.14 2007/09/21
822 Fixed bad memory reference in ZOOM_record - cuased by member not being
823 initialized. This was a problem only in YAZ 3.0.12.
825 Fixed bug in conversion from MARC to XML: Non-XML characters in control
826 fields were not removed.
828 Changed the way C code is generated from codetables.xml. Made a MARC-8
829 conversion trie for each characterSet section rather than codeTable.
830 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
831 of codetables.xml from Larry Dixson, LOC. Bug #1464.
833 --- 3.0.12 2007/09/12
835 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
836 from ZOOM_record_error).
838 ZOOM C function ZOOM_record_get returns record schema for type="schema".
840 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
842 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
844 Better SRW-to-Bib-1 diagnostic mapping.
846 ZOOM C and yaz-client announces SRU version 1.2 by default.
848 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
851 Fixed in yaz_sru_decode to allow other version than 1.1.
853 --- 3.0.10 2007/08/22
855 Added support for SRU scan for ZOOM.
857 Added support for the use of the older versions or Extended Service
858 Update in ZOOM. To faciliate this, an option "updateVersion" may be
859 set to the version , 1=first, 2=second, 3=third. The third version is
860 what ZOOM C has used so far. And that, obviously, is the default.
862 Added support for CCL queries in Z39.50 queries sent to the GFS (and
863 therefore in Zebra and in SimpleServer-based applications). The new
864 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
865 qualifier file used to transform incoming CCL queries into Type-1 RPN,
866 which is passed into the back-end search callback function.
868 Added support for HTTP Basic authentication in clients: the SRU/W
869 codec encodes the username/password elements of the PDU structure
870 appropriately, and these may be set using the "user" and "password"
871 options in ZOOM-C applications (the same options that are used for
872 Z39.50 authentication).
876 Fixed bug #1208: SSL appears to be broken in ZOOM.
878 Fixed bug #1206: Libxml2 include path weirdness.
880 Added oid_name_to_dotstring.
882 Allow elementSetName to be specified for ZOOM C record update.
884 Allow waitAction to be specified for ZOOM C based for Extended Services.
886 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
887 syntax OID. Bug introduced in YAZ 3 series.
889 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
893 Fixed bug #1157: yaz-client does not read .yazclientrc from current
894 directory. yaz-client now reads commands from file given by option -f
895 if specified; then tries to read .yazclientrc in current directory.
896 Failing that, it reads .yazclientrc from user's home directory.
898 Added support for correlationInfo Note and ID for Record Update via
901 Added yaz-client command querycharset which specifies character set for
902 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
903 (termListAndStartPoint).
905 Charset ISO5428:1984 is an alias for ISO5428-1984.
907 Implemented a way to perform scan in a result set using Z39.50. This
908 is achieved by attaching the result set name in the characterInfo
909 (type InternationalString) of OtherInformation in the Scan Request PDU.
910 The result set is identified in the otherinformation by the new OID:
911 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
912 This allows for scan in result set and faceted search . Zebra did some
913 of this in the APT term using attribute type 8 and value being result
914 set. Using the OtherInformation approach for this is cleaner and easier
915 to work with in proxies and the like. This facility can be used in
916 yaz-client using new command setscan which takes a result set as first
917 argument, start position (APT) as second.
919 Changed decoding of SRU XML packed records to deal with servers that
920 have recordData with XML data with multiple root nodes. Also make
921 comparison for recordPacking case insensitive. Again, one server
922 returns "XML" where others return "xml".
924 For SRU responses allow Content-Type application/xml as well as text/xml.
928 Fixed bug in character set conversion of BER strings. Bug introduced
933 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
935 For OID class, use oid_class consistently.
937 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
940 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
941 character set for bibliographic information interchange". By Giannis Kosmas.
943 Added documentation on new OID API.
947 Changes to generic frontend server interface: added new member
948 'query_charset' for bend_initrequest structure. A backend init handler
949 should set this member to its native character set for query terms.
950 When defined, the frontend server logic will announce this character set
951 to a client if the negotiationModel bit is set by the client. All server
952 implementors are encouraged to specify this. If a backend server does not
953 specify this a warning is issued using yaz_log(YLOG_WARN,..).
955 Added CCL utility to remove terms (stop words) from resulting RPN
956 tree. This is handled by functions with prefix ccl_stop_words_ .
958 New ZOOM C option, "rpnCharset", which allows client-side conversion of
959 terms in RPN queries.
961 Clean-up the CCL API. Moved some internal structures from ccl.h to
962 private header cclp.h. Changed ccl_parser_create so that a Bibset must
963 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
964 This is replaced by ccl_parser_find_str which takes a string instead.
966 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
967 libyaz.la is the core of YAZ except the generic frontend server and
968 does not depend on POSIX threads anymore. libyaz_server.la is the
969 generic frontend server facilities and uses POSIX thread functionality
970 if available. The libyaz.la no longer depends on POSIX threads because
971 the number of global structures is limited. NMEM no longer re-uses blocks
972 between threads ; it simply free's memory immediately but allocates in
973 "large" chunks as usual. We don't expect any performance penalties
974 because of this. The yaz_log system is still using a global log_level so
975 caution must be taken when modifying it with yaz_log_init_.. +
976 yaz_log_mask_str. This, however, should not cause any trouble because
977 these functions are called during initialization of application code
978 anyway. `yaz-config --libs server` returns libs for server applications;
979 `yaz-config --libs` returns libs for non-server applications.
981 New OID database - with public definitions in oid_db.h. Removed old OID
982 database including the head oid.h and definitions such as enum oid_value
983 and struct oident. The new OID database uses the same string names as
984 before but the 'protocol' is gone. There are now only two representations
985 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
986 converts from string to OID; functions with prefix yaz_oid_to_string
987 converts the other way.
989 Change to emit_term() in CQL-to-PQF query translation: when a term has
990 the /regexp relation modifier, do not process it for leading and
991 trailing "^" and "*", which have quite different meanings in regular
994 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
995 write handlers no longer carries a 'last' parameter. This will make
996 yaz_iconv flush "less" characters. A flush is performed by call to
997 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
999 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1000 removed, because function yaz_query_to_wrbuf does the same.
1002 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1003 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1005 Deprecated MARC utility functions removed.
1007 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1010 Branch split: YAZ_2_1_55_branch
1012 --- 2.1.54 2007/03/16
1014 Fix to ZOOM-C so that transparent reconnection is properly handled on
1015 connections that are in asynchronous mode.
1017 Fixed compilation on OpenBSD 4.0.
1019 Large strings in GRS-1 records are now properly displayed in yaz-client.
1021 Added character conversion support for "advancegreek"; based on patch from
1024 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1025 sequence is met. Before the error was not set so it would be unknown.
1027 Adjust yaz-marcdump MARC reader so that it skips until record separator
1030 --- 2.1.52 2007/03/07
1032 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1033 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1034 fd_set structure used as a bitmask for the FDs to be selected on.
1036 Using ACX_PTHREAD macro to check for POSIX threads.
1038 Fixed have-vsnprintf check.
1040 --- 2.1.50 2007/02/23
1042 Fixes for configure on BSD. Bug #900.
1044 Added snprintf/vsnprintf wrappers for systems that don't have
1045 limits (heavens forbid).
1047 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1048 created before all previous tasks were completed and removed from the
1049 task queue, the new task could be removed by a mistake.
1051 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1053 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1055 Fixed bug #832: Problem with MARC/charset in yaz-client.
1057 Fixed bug #668: save command line history for yaz-client.
1059 Fixed bug #830: pkg-config support.
1061 --- 2.1.48 2007/01/23
1063 Extended ZOOM result set options with two options that may be read by
1064 a client: resultSetStatus and presentStatus with values as specified for
1066 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1068 Fixed bug #827: Using SSL fails on Debian etch.
1070 Fixed bug #826: Weird looking chars for set of MARC records.
1072 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1073 that is treated as an ItemOrder with itemRequest being an XML document
1074 external. The value of "doc" is the content.
1076 Extended the GFS search facility. New member of bend_search_rr
1077 'estimated_hit_count' signals that hits is known to be an estmate
1078 (higher or lower than real hit count). New member 'partial_resultset'
1079 signals that the search was partial (hit count is lower or equal than
1080 real hit count). For Z39.50, the information is stored in resultSetStatus
1081 member of SearchResponse APDU. For SRU, the information is signalled
1082 via SRU diagnostic 59: "Result set created with valid partial results
1085 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1087 --- 2.1.46 2007/01/13
1089 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1091 Added ZOOM_connection_peek_event.
1093 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1094 the following new functions:
1095 ZOOM_event_nonblock, ZOOM_connection_process,
1096 ZOOM_connection_get_{socket,mask,timeout},
1097 ZOOM_connection_fire_event_{timeout,socket}.
1098 The existing blocking event handler, ZOOM_event, is a wrapper for the
1099 + blocking ZOOM_event_sys_{poll,select}.
1101 Implemented function ccl_xml_config which parses XML version of CCL
1102 configuration (bug #798).
1104 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1106 Added timings utility (yaz/timing.h)
1108 --- 2.1.44 2007/01/03
1110 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1113 Fixed bug #779: Rotation of apdu.log fails.
1115 Fixed for character set conversions:
1116 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1117 Honor G1 set in MARC-8 decoding.
1119 --- 2.1.42 2006/12/17
1121 Fixed bug #775: char conversion does not handle Alternative UTF-8
1124 Implemented function yaz_marc_read_line which parses MARC line format
1125 records. There is a wealth of formats out there. So far, this function
1126 reads line records produced by yaz_marc_write_line.
1128 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1129 more generic and easier to remember(!) options: -i format and -o format
1130 which specifies input format and output format respectively - where
1131 format is one of "marc", "marcxml", "line", "marcxchange".
1133 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1134 does not print anything except warnings for records.
1136 For yaz-marcdump, added support for MARC split into files (-s) with a given
1139 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1140 spec, at http://www.loc.gov/standards/sru/record-update/
1141 This has changed the binary layout of the following structs:
1142 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1143 bend_update_rr . Patch by Ko van der Sloot.
1145 Added GFS utility function bend_assoc_is_alive which returns 1 if
1146 association is still alive (client is connected); 0 otherwise (client
1147 closed connection). This allows busy servers to stop working for
1150 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1151 been a separate piece of software. This version of ziffy has been modified
1152 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1154 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1156 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1157 Client code may now interrogate options such as "init_opt_sort" to
1158 find out whether the server claims to support various options.
1160 --- 2.1.40 2006/11/27
1162 Added utilities yaz_{set,get}_esn to set/get element set name from
1165 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1166 of YAZ and has been so since YAZ 2.1.10.
1168 Implemented ZOOM_record_error which returns error information for
1169 record (surrogate diagnostic).
1171 --- 2.1.38 2006/10/31
1173 Updates for SRU Update by Ko van der Sloot:
1174 1. Changed name from "operation" to "action"
1175 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1176 versions in the code, marked as 'backward compatible'.
1177 3. Added diagnostics for SRU Update.
1179 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1181 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1183 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1185 For GFS, fixed problem with SRU diagnostic 'First record position out of
1186 range' being issued for 0 hits.
1188 zoomtst10 part of Windows Build.
1190 --- 2.1.36 2006/10/13
1192 Implemented yaz_filepath_comp which splits a path into file path
1193 components (required by Zebra 2.0.3+).
1195 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1196 BSD inspired license until now so this should not have any real impact on
1197 anybody. See http://www.opensource.org/licenses/bsd-license.php
1199 Fixed bug #687: Missing log lines.
1201 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1204 Fixed bug #689: SRU diagnostics to be added.
1206 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1207 whether a connection is idle (no more work do do).
1209 --- 2.1.34 2006/10/04
1211 Change type of optval from long to int for invocation of setsockopt with
1212 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1214 Added support for specifying the max log file size for the Generic
1215 Frontend Server. The size is given with option -r.
1217 --- 2.1.32 2006/09/21
1219 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1221 --- 2.1.30 2006/09/17
1223 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1226 Fixed bug in Generic Frontend Server that could cause a server to stop
1227 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1229 For the generic frontend server, the maximum record size is used as maximum
1230 size of incoming packages (SRU + Z39.50). The value until was previously
1231 only used in Z39.50 Init negotiation and, later, in a session controlled
1232 sizes of records returned. This is controlled using -k option. It can be
1233 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1235 --- 2.1.28 2006/09/04
1237 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1240 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1242 New option for yaz-marcdump -lpos=value which allows setting a portion
1243 of MARC header to a certain value.
1245 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1247 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1248 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1250 --- 2.1.26 2006/08/15
1252 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1255 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1257 --- 2.1.24 2006/08/08
1259 Fixed MARC ISO2709 encoding routines to deal with character set
1262 Minor changes to GFS logging. Database included in search request log
1265 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1266 cached/multiple records.
1268 Shared libraries are built by default on Unix+configure.
1270 Changed cql2pqf transformation to use a different evaluation order. The
1271 new order is: always, relation, structure, position, truncation, index
1272 and relationModifier. Old order was: always, relation, relationModifier,
1273 structure, index, position, truncation. Note that the the latter ones
1274 override former ones for identical attributes.. The new scheme means that
1275 it is possible to override any existing attribute with a relationModifier.
1276 And also that it is possible to override everything for the index rule
1277 (except the ones listed in relationModifier). No order is perfect but this
1278 one, we believe, covers more real cases.. The "always" should have been
1279 called "default", since the attributes there can be overridden with all
1282 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1283 compilation phase, but also for yaz-config --cflags output. This allows
1284 us to have public headers with Libxml2 stuff in them . It should also,
1285 eventually, make Libxml2 checks redundant in packages using YAZ, such
1288 --- 2.1.22 2006/06/15
1290 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1291 stored in uri, message and details.. Previously diagnostics were stored
1292 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1293 compatibility.. but he's probably the only one affected, so.
1295 Added support for CCL, compiled on the client side, in ZOOM-C. This
1296 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1297 input; the resulting query objects can be used for for searching with
1298 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1300 YAZ' configure searches for OpenSSL by default.
1302 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1303 SL_CTX_use_certificate_file. See
1304 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1305 for more info. Thanks to Ko van der Sloot.
1307 --- 2.1.20 2006/06/02
1309 Bug #600: SRU GET, POST support for yaz-client. Introduced
1310 command 'sru' which selects method SOAP/GET/POST.
1312 Allow missingValueAction to be specified for the sortspec string -
1313 function yaz_sort_spec. By default, the missing value action is null.
1314 Use ! to specify "abort". Use = followed by stringvalue to specify default
1317 Ensured that Present-handler (if defined) is called in GFS before any call to
1318 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1319 searchRetrieve requests.
1321 Documentation for YAZ is now based on the Docbook XML/XSLT using
1322 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1323 is no longer depending on jade/openjade or docbook-to-man scripts.
1324 PDF is no longer part of the distribution - but can optionally be
1325 made using DSSSL/jadetex or FOP.
1327 Added retrieval handling support in Generic Frontend Server to support
1328 conversion between MARC/XML as well as XSLTtransforms. See
1329 etc/yazgfs.xml for an example.
1331 Added Authentication support to Generic Frontend Server in SRU
1332 mode. Authentication using HTTP Basic is supported, as is the use
1333 of 'x-username' and 'x-password' parameters in the request itself.
1335 Added support for a new character set MARC8s identical to MARC8 except
1336 that it converts combined characters to single Unicode characters in the
1337 Latin-1 range (when possible).
1339 --- 2.1.18 2006/04/24
1341 ASN.1 compiler 0.4: generates brief Doxygen file header for
1342 generated .h/.c files.
1344 Utility yaz_iconv now supports conversion to MARC-8.
1346 New facilities for the MARC module. The reading - and writing of
1347 content are separate methods for the yaz_marc_t handle. The following
1348 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1349 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1350 format). Write functions have prefix yaz_marc_write_.. The existing
1351 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1352 available. Removed support for OAI-MARC and simplexml (not the
1353 simplexml from PHP5).
1355 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1356 to be returned for this connection.
1358 --- 2.1.16 2006/03/31
1360 Allow multiple languages and charsets to be specified with
1361 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1362 negcharset iso-8859-1,utf-8
1364 Translation of proximity nodes from CQL into PQF now works.
1366 Moved to automake 1.8, 1.9.
1368 Added function yaz_log_set_handler which allows a log handler to be
1369 installed. This handler will be called for all log messages. Output
1370 to file is also produced; but that can be disabled by passing NULL
1371 fname to yaz_log_init_file.
1373 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1375 For SRW (including GFS), accept application/soap+xml as content-type
1378 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1379 produces NO stylesheet reference even if a default stylesheet is specified
1382 --- 2.1.14 2006/03/14
1384 Updated Windows package to include yazd.dll + yazd.lib for the
1385 Development component.
1387 If the environment variable YAZ_LOG is set, then it is used as a
1388 string indicating the default level of logging to use if not
1389 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1390 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1391 used as before. So, for example, to omit warnings from YAZ logging,
1392 export YAZ_LOG=-warn
1394 cql_transform() now map structure and other attributes before indexes,
1395 so that index-specific structures and other attributes can override
1396 defaults. So now a combination of mapping specifications such as:
1398 index.dc.date = 1=date-modified 4=5
1399 does the right thing.
1401 cql_transform() now also respects the "always" mapping specification,
1402 which establishes an initial set of attributes to be used for all
1403 terms except where overridden by more specific attributes associated
1404 with the index, relation or modifier.
1406 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1407 which mode to use; one of "post", "get" or "soap" (SRW, default).
1409 Fixes for yaz_iconv routines: changed trie-based character set conversions
1410 to use only non-negative values for bit fields due to Sun's C compiler not
1411 supporting negative values.
1413 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1414 sequences where not read correctly. Fix by Rustam Usmanov.
1416 Updated win/makefile to use options, settings which makes things
1417 compile with VS C 2005.
1419 --- 2.1.12 2006/02/01
1421 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1423 In ZOOM socket code, use select instead of poll on MacOSX.
1425 ZOOM-C now support client-side compilation of CQL into RPN that is
1426 sent to the server, enabling CQL to be used against all Z39.50
1427 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1428 ZOOM_query object, and submit it using ZOOM_connection_search().
1429 The CQL-to-RPN translation uses a configuration file, the name of
1430 which must be specified in the Connection's "cqlfile" option.
1432 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1433 function, which takes as its start-term parameter a ZOOM_query object
1434 (which may have had either CQL or RPN set into it).
1437 --- 2.1.10 2005/11/29
1439 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1440 GFS to support this as well. Backend handler, bend_srw_update, does the
1441 update work. Code contributed by Ko van der Sloot.
1443 Allow retrieval of Search Result-1 information in ZOOM by the use of
1444 options that are attached to a result set. ZOOM documentation updated
1447 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1448 UTF-8 conversion. Patch by Raj Patel.
1450 Added option -m to GFS to control formatting of timestamps in log file.
1452 Added 'exit' as synonym for 'quit' in yaz-client
1454 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1455 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1456 for the new members. Patch by Ko van der Sloot.
1458 Added support for SRU POST. It is supported for content-type
1459 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1461 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1462 Instead make the library libyaz.la multi-threaded. Threading as a whole
1463 can still be disabled by configure option --disable-threads. Previosly,
1464 with older GLIBCs there were problems with MT libs under Apache. This
1465 has now been fixed a long time ago.
1467 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1470 CQL module modified to be case insensitive for relations/indexes/operations.
1472 Fixed bug in CQL transform code: incorrect value relationModifieder
1475 Added 'show all' command for yaz-client which retrieves all results
1478 Added new yaz-client, xmles, which takes a (private) OID and
1479 a document to be sent as an extended service request.
1481 Describe new yaz-client commands wait_response and set_auto_wait.
1483 Increase TCP/IP listener backlog from 3 (which I am guessing was
1484 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1485 that the socket will queue as many incoming connections as it's able
1486 to handle ongoing connections. In other words, it will never now
1487 refuse a connection that it would be able to handle merely because
1488 it's not got around to accepting() enough of the pending connections
1489 yet. This is the behaviour anyway under Linux, where the listen()
1490 argument is ignored; but not under BSD and on systems such as
1491 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1492 YAZ-based servers should now be uniform across operating systems in
1495 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1496 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1497 This allows yaz-marcdump to read large MARC batches (>2 GB).
1499 Modified all YAZ source files - except the source which is auto-generated
1500 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1503 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1504 corresponding to the existing *_setl() function. These allow option
1505 values containing arbitrary valuues.
1507 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1508 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1509 except that it returns an indicator of whether or not the sort
1510 criterion was accepted (0 for OK, -1 for invalid).
1512 --- 2.1.8 2005/06/07
1514 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1515 MARC output rather than returning "new" buffer.
1517 yaz-client warns about unknown init options.
1519 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1521 --- 2.1.6 2005/05/24
1523 Added support for SRW sort in Generic Frontend Server. Patch
1524 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1525 sortKeys - or NULL if none is provided.
1527 Fixed bug #307: It was impossible to specify indefinite/no timeout
1528 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1531 Added support for multiple languages and charsets to be specified in
1532 ZOOM. Each charset/language is separated by a blank. If negotiation is
1533 in effect in init-response, Option
1534 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1535 Code based on patch by Vasiliy Osadchuk.
1537 Fixed bug #306: infinite recursion that occurred when calling
1538 yaz_log_level_init as the first call (before other log level or
1541 Fixed bug in scan handling in front end server: if preferred-Position-In-
1542 Response was non-present, a NULL pointer referece was performed.
1544 --- 2.1.4 2005/04/26
1546 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1547 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1548 now defined for all those error codes. So instead of putting 109 in
1549 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1550 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1552 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1555 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1557 Program yaz-client now exits and produces an error message if multiple
1558 Z39.50 servers are specified on the command line (none or one allowed
1561 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1564 --- 2.1.2 2005/03/16
1566 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1568 Fixed bug #272: Preserve spacing for CCL terms.
1570 --- 2.1.0 2005/03/14
1572 Added support for virtual hosts and multiple backend servers for
1573 the YAZ frontend server. The configution is XML based and
1574 support specificition of CQL to RPN mappings and explain information.
1575 See section "Virtual Hosts" in the YAZ manual.
1577 Extended OPAC display utility. OPAC display utility renders
1578 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1579 to supplement yaz_marc_decode_wrbuf.
1581 Fixed a bug in MARC decoder that could caused it to crash for some
1582 invalid MARC records. More diagnostics and warnings where added in
1583 XML output (warnings, etc are stored in comments).
1585 --- 2.0.34 2005/02/08
1587 Fixes for UNIX domain sockets. Bug #261.
1589 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1591 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1592 Added yaz_marc_subfield_str which defines subfield lead string which is
1593 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1594 yaz_marc_endline_str which defines end of fields string used in
1595 YAZ_MARC_LINE format. Default string is newline.
1597 Experimental support for MarcXChange. This format can be produced
1598 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1599 http://www.bs.dk/standards/MarcXchange.xsd
1601 Added yaz-client commands scansize that sets maximum number of
1602 entries to be returned by scan.
1604 --- 2.0.32 2005/01/11
1606 Added support for SRW scan in yaz-client and Generic Frontend Server.
1608 * Added whereInList member to SRW Scan Term.
1610 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1612 Fixed NMEM system to return aligned blocks on the smallest boundaries
1613 that are suitably aligned for all possible types on the particular
1614 architecture YAZ is being built for.
1616 --- 2.0.30 2005/01/04
1618 Fixed numerious warnings that was issued with newer versions of GCC.
1620 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1621 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1624 Make YAZ Generic Frontend Server slightly faster.
1626 Enhance (and reduce) logging for Generic Frontend Server.
1628 Revert YAZ log system so that it flushes every write operation
1629 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1631 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1632 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1633 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1634 will effectively disable old definitions.
1636 --- 2.0.28 2004/11/09
1638 Added yaz_log_time_format which specifies log format using
1641 Added yaz_log_module_level which returns mask for a module. Value
1642 is non-zero mask a if module is enabled; zero if disabled.
1644 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1645 in include/yaz/cql.h.
1647 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1649 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1651 Fixed bug #172: RPM builds does not enable SSL.
1653 Doxyfile.in part of dist. Doxyfile generated by configure.
1655 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1656 are given and the corresponding component does not exist.
1658 Extend CCL documentation in YAZ reference. Describe r=r.
1660 --- 2.0.26 2004/10/01
1662 Fixed MARC->MARCXML conversion to properly deal with
1663 fields, subfields, indicators having non-ASCII characters.
1665 Fixed MARC->MARCXML conversion so that ASCII control characters
1666 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1669 Added YAZ GFS support for conversion from Z39.50 surrogate
1670 diagnostics to SRW surrogate diagnostics.
1672 Bug fix: YAZ GFS did not return schema in explainResponse.
1674 --- 2.0.25 2004/09/30
1676 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1677 now converts recordSchema to elementSetName as well as schema URI.
1679 Fixed bug in COMSTACK that prevented HTTP request packages from being
1682 --- 2.0.24 2004/09/29
1684 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1685 does not require white-space before and after the dash in a range, e.g.
1686 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1689 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1690 due to new GCC removing "redundant" code.
1692 Added yaz-client commands scanpos and scanstep that sets preferred
1693 position and step-size for scan.
1695 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1697 Added CCL utility ccl_qual_buf which parses one or more CCL
1698 spec lines in a buffer.
1700 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1701 of name and value - ignoring empty lines and comments.
1703 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1705 Added odr_get_element_path which returns current element path for an
1706 ODR handle. This utility is useful in error handling or user-defined
1709 Added ODR_PRINT utility odr_set_stream which is is a more generic
1710 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1711 to a write function and pointer to close function. The close function - if
1712 non-NULL - will be called during odr_destroy.
1714 Fixed bug in CCL parser where truncation char was not removed from
1715 right side when truncation=both was in effect.
1717 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1720 --- 2.0.23 2004/08/11
1722 Fix buffer overrun in CQL parser when dealing with proximity (%).
1724 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1725 to UTF-8/UCS conversion is now only based on codetables.xml.
1727 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1729 --- 2.0.22 2004/08/06
1731 Add support for more "commit changes" in ZOOM (uses Extended Services).
1733 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1736 Yet another small fix for configure of SSL.
1738 --- 2.0.21 2004/05/14
1740 Fix SSL libs for configure when --with-openssl=DIR is given.
1742 --- 2.0.20 2004/05/10
1744 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1746 SSL comstack now uses yaz.pem certificate file on server side
1747 by default. Certificate filename can be configured by calling
1748 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1750 Fix bug regarding multiple calls to ZOOM_connection_connect.
1752 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1754 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1755 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1757 ZOOM now allows inspection of X509 peer certificate for verification.
1758 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1760 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1761 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1762 as "modular" but it simplifies things.
1764 Added cs_get_peer_certificate to that returns peer X509 PEM.
1766 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1767 NULL if SSL is unavailable.
1769 Documentation about MARC decoding tools.
1771 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1773 --- 2.0.19 2004/03/30
1775 Rename CHANGELOG to NEWS to follow GNU style packing.
1777 Fix bug with missing initialization of member in init_diagnostics.
1778 This bug affects threaded version of GFS server.
1780 --- 2.0.18 2004/03/20
1782 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1785 Ensure zlib.dll is packed with Windows install.
1787 --- 2.0.17 2004/03/17
1789 Fix encoding of xsd:string to use text instead of CDATA.
1791 Fix endless loop in CQL parser with unbalanced ".
1793 Use a more compact way to store MARC-8 conversion tables.
1795 --- 2.0.16 2004/03/16 Debian only
1797 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1800 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1805 --- 2.0.15 2004/03/01
1807 Another fix for decoding of XML packed records.
1809 --- 2.0.14 2004/02/25
1811 Fixes for Chunked encoding. White space not ignored after length spec.
1813 Update NS and use default NS for SRW diagnostic elements.
1815 --- 2.0.13 2004/02/23
1817 Implement ZOOM_resultset_cache_reset which resets record cache.
1819 Implement ZOOM_resultset_sort which sorts a result set.
1821 Implement chunked HTTP transfer.
1823 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1825 --- 2.0.12 2004/02/16
1827 Added member 'schema' to bend_explain_rr structure so that backend
1828 can specify explain record identifier. Defaults to Zeerex 2.0.
1830 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1832 --- 2.0.11 2004/02/16
1834 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1837 Added init command for yaz-client which sends "extra" init request.
1839 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1840 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1842 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1844 Make ZOOM error code for "invalid query".
1846 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1848 --- 2.0.10 2004/02/05
1850 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1853 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1855 Added option -p <file> to make Generic Frontend Server to write PID file.
1857 Added option -D to put Generic Frontend Server in background on its own.
1859 Make ZOOM C recognize option "password". If unset, "pass" is used
1860 (for backwards compatibility).
1862 Fixed a bug in Generic Frontend Server that could make it crash if a
1863 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1866 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1867 Must be issued before open, in order to be in effect.
1869 --- 2.0.9-6 2004/01/12 Debian/Windows
1871 Make the SRU server more picky WRT unknown params, etc.
1873 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1875 New YAZ client command, options, that sets Z39.50 options.
1877 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1878 options from a string of tokens (one token for each option bit).
1880 Update SRW diagnostic code messages.
1882 --- 2.0.9-5 2004/01/07 Debian/Windows
1884 Handle user defined stylesheet for SRW/SRU.
1886 --- 2.0.9-4 2004/01/06 Debian/Windows
1888 Fix bug in decoding of Content-Length.
1890 --- 2.0.9-3 2004/01/06 Debian/Windows
1892 Fix a bug with decoding of XML packed records.
1894 --- 2.0.9-2 2004/01/05 Debian only
1896 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1898 Fix bug in SRW/SRU diagnostics decoding.
1900 --- 2.0.9 2004/01/05
1902 Fixed bug in Generic Frontend Server which could drop records exceeding
1903 preferred message size. Reported and fixed by Irina Dijour.
1905 Fixed calculation of package size for structured records in Generic
1906 Frontend Server. Reported and fixed by Irina Dijour.
1908 Fixed namespace for SRW/SRU diagnostics.
1910 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1912 --- 2.0.8 2003/12/22
1914 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1915 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1918 CQL changes to reflect recent changes to the specification:
1919 * Documentation talks about context sets instead of index sets.
1920 * Documentation talks about indexes instead of qualifiers.
1921 * The CQL-to-PQF transformer's configuration file now uses
1922 "index.set.name = <attributes>" instead of the old form
1923 "qualifier.set.name = <attributes>". (Both forms are still
1924 understood but the latter is deprecated.)
1925 * CQL terms with no explicit index specified are now interpreted as
1926 cql.serverChoice instead of srw.serverChoice (which of course
1927 behaves exactly the same.)
1929 --- 2.0.7 2003/12/16
1931 MARC conversion can now generate ISO2709 output in another
1932 character set. yaz-marcdump uses this facility if you invoke it
1935 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1936 functions from there can be used from C++.
1938 --- 2.0.6 2003/12/04
1940 Frontend server now transfers memory from decoded packages to stream
1943 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1944 references to show up.
1946 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1947 the ZOOM Abstract API. The older names for the same options are still
1948 also supported for the benefit of old applications.
1950 ZOOM-C supports "implementationId" and "implementationVersion" options
1951 to go along with "implementationName". These allow the user code to
1952 specify identification strings to be sent to servers.
1953 Add OID for the new ExtLite attribute set.
1955 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1956 as requested/supplid by Ere Maijala <ere@atp.fi>
1958 For generic frontend server, reverse the order of
1959 "toolkit-supplied / application-supplied" strings sent as implementationId,
1960 Name and Version. Also, remove the spaces around the slash. This brings
1961 the GFS in line with the behaviour of ZOOM-C on the client side.
1963 Add function ZOOM_scanset_display_term.
1965 yaz-client shows scan displayTerm if present.
1967 Utility yaz-iconv is now installed by default along with the man page
1970 Extend configure check for OpenSSL to use pkg-config where available (such
1973 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1974 server to specify uid/gid/mask for socket using the format
1975 unix:[user=uid,][group=gid,][umask=mask,]file=path
1976 If file= is omitted the existing format is assumed, e.g.
1978 in which case the mask is 0666 (rw for everybody).
1980 Major restructure of YAZ source. All source in libyaz is in src directory.
1981 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1982 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1984 Added man page for utility yaz-marcdump (used to be called marcdump).
1985 yaz-marcdump is installed by 'make install'.
1987 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1988 of incoming package failed.
1990 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1992 Change prototype of odr_perror: add const to message string.
1994 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1996 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1997 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1998 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1999 DNS lookup. There should not be any compatibility problems with this
2000 assuming that blocking=1 or 0 is used.
2002 Fix bad reference in UNIX comstack in function cs_addrstr.
2004 Fix for compilation on AIX.
2006 The generic front-end server (server/seshigh.c) now supports returning
2007 Init diagnostics to the client in User-information-field, in
2008 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2011 --- 2.0.4 2003/09/04
2013 Allow any CQL relation (not just all,any,exact,scr).
2015 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2016 that features the same UI.
2018 Implemented command update0 in YAZ client which is equivalent to
2019 update but uses old of Ext Update ASN.1.
2021 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2022 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2023 Previously no OID was used for this info.
2025 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2026 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2027 returns 'malformed search term' otherwise.
2029 SortResponse member resultCount now set to NULL in sort handler of
2032 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2035 Add three new utility functions for translating OIDs between various
2036 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2037 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2038 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2039 char *oid_to_dotstring(const int *oid, char *oidbuf);
2040 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2042 Reverted modifications for ES Update definition for z_IU0Update
2043 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2044 is back to YAZ 2.0.2.
2046 String value attributes for CCL parser.
2048 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2049 which their FirstSearch server returns in Init responses, sometimes
2050 carrying useful diagnostic information when Init fails. This has the
2051 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2052 "z39.50/oclcui.asn", where its definition is somewhat different from
2053 what OCLC document on their web-site, as required to interoperate with
2056 Support for anonymous authentication in yaz-client. Use the command
2059 * Fix the OID of the Index Data-local "admin" Extended Service from
2060 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2061 the 1000, which indicates a locally-defined OID, was a mistake.
2063 --- 2.0.3 2003/06/20
2065 Fix CCL directive @case handling so that it affects string match for
2066 both CCL keywords and qualifiers.
2068 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2069 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2070 Decoder has been updated with ASN.1 changes as listed in
2071 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2072 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2073 z_IUUpdate, remains unchanged.
2075 ZOOM_record_get may now return a record in a specific character set.
2076 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2077 "from" is the character set of record as returned by target. "to" is
2078 the character set to be returned. If omitted, "to" is UTF-8.
2080 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2082 New ODR utility, odr_getelement, which returns name of element for
2083 which encoding/decoding failed.
2085 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2086 in cases where a required element was omitted.
2088 Bug fix: some MARC8 sequences were not converted.
2090 New ZOOM option "step" which specifies number of records to be
2091 retrieved in one chunk. Used in conjunction with "start" and "count".
2093 SRW support for yaz-client. Use scheme http: to use it, e.g.
2096 yaz-client no longer does (un)intelligent character set conversions
2097 by default. Can be enabled with charset and marc_charset commands.
2099 xmalloc trace fix for 64-bit systems such as DEC alpha.
2101 Solaris 2.6 compile fix.
2103 New function, cql_strerror() translates SRW error codes, as returned
2104 by cql_transform_error(), into human-readable English strings. Used
2105 in yaz-client diagnostics when appropriate.
2107 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2108 converts it into a type-1 query which is sent to the server. This
2109 makes CQL available for use with all Z-servers, as opposed to the tiny
2110 minority that can handle CQL queries themselves.
2112 --- 2.0.2 2003/04/28
2114 New Debian package layout similar to the Redhat Package layout.
2116 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2117 and search result respectively.
2119 --- 2.0.1 2003/04/25
2121 Redhat package is now several packages: libyaz (runtime libraries),
2122 libyaz-devel (development and documentation, and yaz (utility programs).
2123 Package spec file by Morten Bogeskov.
2125 New member 'schema' in struct bend_fetch_rr which the name of requested
2126 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2127 handler MAY set this to reflect the schema of the returned record.
2129 New member 'display_term' in struct scan_entry. GFS now sets member entries
2130 and allocates scan entries to be filled by user scan handler. In previous
2131 version, entries member was allocated by the scan handler. That still works,
2132 but the GFS will ignore member display_term - assuming it was NOT set by
2133 the handler. The fact that the GFS now allocates the entries both allows
2134 for new members and makes a scan handler easier to write.
2136 Fix CQL lex buffer overflow.
2138 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2139 SRU default recordPacking is string.
2141 SRU protocol support for frontend server.
2143 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2145 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2147 Added scan for the ZOOM shell (zoomsh).
2151 * String Identifers for Schemas (Amendment 5).
2152 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2153 Old definition for schema
2154 Odr_oid *schema; /* OPT */
2159 Z_InternationalString *uri;
2160 #define Z_Schema_oid 1
2161 #define Z_Schema_uri 2
2164 * resultCount parameter to Sort Response (Amendment 1).
2165 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2167 Support for SRW 1.0 over HTTP. This is an optional feature and
2168 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2171 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2172 on the same port. SRW SearchRetrieveRequests are mapped
2173 to bend_init,bend_search,bend_fetch,bend_close.
2175 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2177 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2178 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2180 ZOOM connections are SRW based if schem http is used for hostname
2181 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2182 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2184 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2185 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2186 distance=n, order=true/false, relation=le, prox unit=word. If
2187 n is omitted, distance 1 is used.
2189 Fixed problem with C compiler include path in wrong order.
2191 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2192 on Solaris. Patch from Ko van der Sloot.
2194 New MARC decode API. All new functions operate on a yaz_marc_t
2195 handle. The most important new functions are: yaz_marc_create,
2196 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2197 decode and destroy respectively. Decoder can produce formats
2198 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2199 include/yaz/marcdisp.h.
2201 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2202 to UTF-8, UCS-32, wchar_t or Latin-1.
2204 * Prototypes for yaz_iconv_-functions moved to separate header
2205 include/yaz/yaz-iconv.h.
2207 Make a few private functions 'static' in unix.c. This prevents
2208 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2210 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2211 are set when Init Response is received.
2213 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2214 but returns diagnostic set as well.
2216 New function yaz_strerror which is a portable wrapper for
2217 strerror/strerror_r/GetLastMessage.
2219 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2220 is returned for MARC. If type is "oai", then OAI MARC is returned.
2222 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2225 --- 1.9.2 2002/11/26
2227 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2229 Fix bad race conditions on SIGTERM and terminate gracefully in
2232 Move retrieval (data1) module to Zebra since nobody seems to be
2235 Add GRS-1 render for ZOOM using same format as yaz-client.
2237 --- 1.9.1 2002/10/05
2239 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2241 Fix broken ESpec handling in data1 module.
2243 SGML reader parses comments and makes them part of the data1 tree.
2245 Added several type casts so that YAZ compiles as C++ code.
2247 ZOOM didn't handle PDU encoding failures properly.
2249 Added more Bib-1 diagnostics (approved extensions).
2251 GNU configure: better check for iconv.
2253 More portable use of accept, getpeername. Check for socklen_t. Use
2254 int/size_t if socklen_t is not defined.
2258 PQF parser rejects bad queries - including those with extra
2259 characters in them. PQF parser used to silently ignore that.
2260 Cleaner API for PQF added, which allows you to get detailed
2261 error information for bad queries (see yaz/pquery.h).
2263 Fixed bug in ZOOM_record_get for type "database".
2265 Implemented mini iconv library supporting conversions between
2266 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2268 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2270 --- 1.8.9 2002/08/20
2272 Fixed ZOOM C record cache so that preferredRecordSyntax and
2273 elementSetName is used to check for already fetched records.
2275 --- 1.8.8 2002/08/02
2277 Added three members in bend_initrequest structure to facilitate
2278 character set negotiation.
2280 Fixed a bug in frontend server that could cause indefinite
2281 loops under rare conditions.
2283 Revised character set utilities (charneg.h) so that encoding
2284 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2286 For PQF, directive @term <type> sets term type for Scan/Search.
2287 Here <type> is general, string, numeric, null. The term type
2288 is inherited - just like @attr.
2290 New call odr_set_charset that sets character set conversion for
2291 international-strings on a ODR stream. Prototype is:
2292 int odr_set_charset(ODR o, const char *to, const char *from);
2293 The InternationalString is still represented as C string in YAZ
2294 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2295 won't). On the protocol level, you can use any encoding.
2297 Support for UNIX sockets in ZOOM.
2299 Solaris recv sometimes returns errno == ENOENT. It is treated as
2300 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2302 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2303 both client and server. Code by Morten Bogeskov.
2305 --- 1.8.7 2002/05/22
2307 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2308 that they can be used directly from Visual Basic. You must recompile
2309 your windows APP if you're using ZOOM.
2311 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2312 Commands "lang" and "charset" sets language and character set respectively.
2313 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2314 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2316 Attributes from multiple CCL fields may be OR'ed rather than merged
2317 using directive "@field or". Fields are still merged by default -
2318 equivalent to "@field merge".
2320 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2323 Fixed bug in zget for parameter ExtendedServicesResponse.
2327 --- 1.8.6 2002/03/25
2329 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2331 Client displays USR.1:SearchResult-1 (hits per term).
2333 Additional Search Info for search in Generic Frontend Server.
2335 Fixed CCL parsing of "field=s".
2337 WIN32 installer - using the excellent NSIS software from nullsoft.
2339 Fixed CCL parsing of "field = - <number>".
2341 Added function yaz_marc_decode that decodes MARC for line mode
2342 display or XML (similar to that used by JZKit).
2344 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2345 Z39.50. But ISO/ILL was, however.
2347 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2348 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2350 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2351 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2353 --- 1.8.5 2002/02/03
2355 New YAZ client features: Command completion and new commands:
2356 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2357 Code provided by Jacob Poulsen.
2359 New call oid_trav, that visits all registered OIDs via callback.
2361 Function ZOOM_record_get now returns const char pointer rather than
2362 void pointer. It saves a lot of type casts.
2364 For YAZ client, command "auth" now allows you to set authentication
2365 in IdPass style. It is enabled when three tokens are given - order
2366 is user, group and password.
2368 Fix memory leaks in MARC record handling for ZOOM.
2370 New option for YAZ client, -k <kilobytes> that sets
2371 maximum record size. Similar to -k option for generic frontend
2372 server and yaz-ztest.
2374 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2376 Prefix query parser reports "fail" when bad attribute set is given.
2378 Fix in MARC decoder. Proximity logging. Fix for attribute set
2379 in scan handler for server. Patches by Shigeru Ishida.
2381 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2384 Configure option --with-openssl=<dir> now works when a directory is
2385 specified. Patch provided by Morten Bogeskov.
2387 New option for YAZ client, -u <auth>, that sets authentication.
2389 ZOOM fix: error information was sometimes "missing", since error
2390 was cleared/reset too when it shouldn't.
2392 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2394 --- 1.8.4 2002/01/04
2396 Scan for ZOOM API. New object ZOOM_scanset. New functions
2397 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2398 ZOOM_scanset_destroy.
2400 New ZOOM function, ZOOM_connection_last_event, that returns type
2401 of last event (such as "receive data", "send data", "apdu received",
2404 New ZOOM option, schema, that specifies schema for retrieval.
2406 New CCL feature. Qualifiers can be aliases for one or more
2407 other qualifiers (if more than one is given, OR is used).
2409 ZOOM uses named result sets if target supports it.
2411 Two new YAZ client commands: . (dot, which sources a script of YAZ
2412 client commands), and ! (to execute shell command.). Implemented
2415 Working on Debian packages.
2417 --- 1.8.3 2001/11/19
2419 YAZ client enables named result sets only if target supports it.
2421 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2423 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2424 with key="host" to get same result.
2426 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2427 Function Z3950_resultset_record(s) returns references to records
2428 "owned" by resultset. To become owner use Z3950_record_clone.
2430 Function z_ext_record handles Extended Services. Thanks to
2433 --- 1.8.2 2001/11/12
2435 CCL Parser fix: ignore token comma when dealing with and-lists.
2437 Documentation updates for COMSTACK.
2439 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2440 Changed prototype Z3950_records. For some functions, int parameters
2441 were changed to size_t.
2443 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2446 New MARC decode/display function, marc_display_exl, which properly rejects
2447 non-ISO2709 records. YAZ client uses it.
2449 --- 1.8.1 2001/10/29
2451 Fix bug: local attribute set wasn't set correctly in PQF strings.
2455 * Old Z39.50 codecs no longer supported.
2457 Added ZOOM C binding. See http://zoom.z3950.org/
2459 Renamed states for COMSTACKs to avoid confusion with events.
2461 Implemented cs_look and proper cs_rcvconnect.
2463 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2465 Configure detects POSIX threads on OpenBSD.
2467 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2468 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2470 When error is returned from present handler, non-surrogate diagnostic
2471 is returned in present response (and fetch handler is no longer called).
2473 * Minor adjustments to pquery parser (PQF). Token characters may be
2474 escaped by using backslash (C-style).
2476 PQF parser allows string attribute values to be specified. For @attr,
2477 non-numeric characters after the equal-sign are treated as strings
2478 (e.g. @attr 9=title).
2480 CCL trunction character may be defined (@truncation in file)
2482 * function zget_ExtendedServicesRequest sets waitAction to
2483 waitIfPossible (was wait).
2485 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2488 CCL operator names may be set in field definition files (CCL_bibset).
2489 See ccl/bib1 for an example.
2491 Fixes in ASN.1 compiler for C++ compatibility.
2493 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2494 and "op_or" to avoid conflict with C++.
2496 Fixed problem with GNU readline detection on Redhat 7.0.
2498 Added step-size for Scan backend handler.
2500 Fixed bug that made the frontend server crash when no attribute
2501 set was specified for scan.
2503 Front-end server automatically switches to original working directory
2504 when installed as an NT service. Previously -w had to be specified to
2507 Added extended attributes for retrieval module (data1), so that data1
2508 records carry d1_readXML/SGML attributes. d1_read also supports
2509 null-data rules ( <tag/>)
2511 On UNIX when POSIX threads are available, a separate library libyazthread
2512 is created. Programmers should link with that library and the yaz library
2513 when using threads. The reason for the split was that some applications
2514 on Linux, such as Apache, doesn't work well when using shared objects that
2517 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2518 (or any frontend server) in SSL mode by specifying ssl: followed by
2519 address. Only tested on UNIX.
2521 Added feature for CCL module. Virtual structure s=al or s=ol generates
2522 and-list and or-list respectively instead of phrase search.
2526 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2527 log_mask_str. This was done to avoid name conflicts with other libraries
2528 (such as other PHP extensions).
2530 Added raw OID member for preferred record syntax (request_format_raw)
2531 and returned record syntax (output_format_raw) for backend fetch method.
2533 Config file yaz-config now accepts options so that it returns specific
2534 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2536 Shared library support for UNIX using GNU libtool.
2538 * Modified backend interface. Request/Response struct's replaced by
2539 one read/write C struct. For example bend_fetchrequest and
2540 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2541 Every handler - even search has to be registered in bend_init
2542 handler. This means that the YAZ library no longer refers to
2543 external functions and it makes it possible to make the whole
2544 thing a single DLL/SO.
2546 Added Segment handler for backend server.
2548 Added Zmbol/Zebra administrative functions to YAZ client.
2550 Threaded frontend server on UNIX (when POSIX Threads are available).
2551 Starting the server with option -T enables multi-threading.
2555 Added configure option --enable-comp/disable-comp to control use
2556 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2557 located in sub directory asn.
2559 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2560 in ${exec_prefix}/bin along with the other programs yaz-client and
2563 GNU automake used to maintain makefiles.
2565 Added several OID's.
2567 Changed retrieval module so that we can load records with no abstract
2568 syntax defined. Tagpaths in these records are fully composed of string
2571 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2575 On UNIX, the generated makefile now supports a proper 'make install'.
2576 The prefix can be set via GNU configure to set the install location
2577 (default is /usr/local).
2579 * YAZ programs client and ztest were renamed to yaz-client and
2580 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2581 locations, such as /usr/bin,/usr/local/bin,etc.
2583 * YAZ Header files were moved from include to include/yaz. YAZ Header
2584 files are referred to as include <yaz/log.h> rather than <log.h>.
2585 The YAZ include path (-I ..) is therefore the same as before. Programmers
2586 should update their #include statements or use -Ipath/include/yaz
2587 instead. The main motivation for doing this change is that YAZ header files
2588 can be installed in "standard" locations /usr/include,/usr/local/include
2589 without introducing conflicts, since ALL YAZ header files are stored
2590 in subdirectory yaz (under /usr/include for example).
2592 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2593 rather than project/workspace files. We switched because project files
2594 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2597 Changed name of logging function, logf, to yaz_log, to prevent name
2598 clash with some math-log functions. The YAZ header log.h defines logf
2599 to yaz_log (#define) so there should be no incompatibilities by this
2602 Added bend_start/bend_stop handlers for server. These handler are
2603 called on start/stop of server. For windows they are called whenever
2604 a service is started/stopped.
2606 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2607 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2608 in util/yc.tcl. The auto-generated C code structures are, in a few
2609 cases, incompatible with the old decoders. There are differences in the
2610 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2611 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2612 The preprocessor variable ASN_COMPILED is defined when the compiled
2613 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2614 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2615 wish to use the old encoders/decoders you can specify --disable-yc
2618 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2619 version so that it supports both new - and old version of DB Update
2621 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2622 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2623 change. The name parameter can be set to 0 in which no name is specified
2624 for the construction. The macros odr_implicit and odr_explicit sets name
2625 parameter to zero for the construction involved. New macros
2626 odr_implicit_tag and odr_explicit_tag are similar to the others,
2627 except that a name parameter is added. For programmers' that don't use
2628 ODR they probably only need to change the call to z_APDU and z_External.
2630 Added access control facility by interfacing the TCP wrapper library.
2631 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2632 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2633 name of the daemon and enables the access control as specified in
2634 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2636 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2637 den Dool <H.M.vdnDool@kub.nl>.
2639 Added reference ID parameter to most functions in server API - refer
2640 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2642 Changed name of ccl library to libccl.a (was ccl.a).
2644 Fixed bug in decoder for Explain (Category TargetInfo).
2646 Added support for GNU readline in client. Thanks to Jacob Poulsen
2647 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2649 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2650 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2651 IMPLEMENTATION! This change was made to the development version before
2652 the ZIG decided to retract the amendment. If any users MUST be
2653 compatible with the original Update definition, PLEASE CONTACT US, and
2654 we will include a separate definition corresponding to the old Update
2655 ES. Note that because of the change to the ASN.1 of the
2656 TaskPackageRecordStructure we cannot define a single structure that
2657 will support both versions.
2659 * Added const modifier to buffer parameter for some ODR/BER encoding
2660 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2661 completeWAIS, odr_dumpBER.
2663 Fixed bug in client.c which caused a crash when a scanResponse didn't
2664 contain positionOfTerm.
2666 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2667 * will cause an error in a client if a non-YAZ target sends both a
2668 * list of Scan entries and non-surrogate diagnostics.
2670 Retrieval module enhancements. Tag sets may be typed in the reference
2671 to it. From the .abs-file the "tagset" directive takes a third optional
2672 integer type for the tag set referenced. From a .tag-file the "include"
2673 directive takes a third optional type as well. The old "type" directive
2674 in the tag set itself is still recognized but acts as the default type
2677 Backend interface change. Individual Scan terms returned from bend_scan
2678 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2679 in include/backend.h.
2681 Retrieval module enhancements. Multiple tag sets and attribute sets may
2682 be specified in abstract syntax specs. Revised the error/warning for
2683 logging messages reported by the retrieval module when reading the
2686 Object Identifier system (oid_..) changed. The API is backwards
2687 compatible but the oid-routines now allocates new OID's when needed.
2688 Raw OID's may be specified in oid_getvalbyname.
2690 YAZ now uses GNU configure to generate Makefile(s).
2692 * Minor changes in some of the member names of DeleteResultSetRequest and
2693 DeleteResultSetResponse. See include/proto.h.
2695 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2696 and added member 'languages' in TargetInfo (which was missing).
2698 Changed the way attribute sets are handled in the retrieval
2699 module. These are now cached, just like the abstract syntaxes
2702 Changed YAZ so that it links with compiled ASN.1.
2704 Added Explain-schema definitions and mapping routines. The following
2705 Explain categories have been implemented: AttributeDetails,
2706 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2708 Fixed minor bug in Windows version of Server Library.
2710 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2712 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2714 Added EXTERNAL: UNIverse Resource Report (non-standard).
2716 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2717 ENUMERATED and SET OF.
2719 * Added 'const' to some of the char pointer arguments for the
2720 functions, data1_read_node, data1_getelementbytagname,
2721 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2724 Fixed bug in data1_insert_taggeddata - the last_child member of
2725 parent wasn't initialised.
2727 * Changed data1_read_record and data1_read_node so that the supplied
2728 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2729 doesn't refer to any parts of the "SGML"-buffer.
2731 Fixed bug in server library (Windows version of statserv_remove).
2733 * Changed code so that it compiles as C++. The type definition
2734 of Odr_fun which is a member of Odr_arm was changed. The result is,
2735 that an explicit typecast is needed for the fun pointer when
2736 using Odr_arm - as in:
2737 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2739 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2741 Implemented the new structured date and time definition as approved
2742 by the ZIG. Added schemaId element to the specificTag in Espec-1
2743 (also approved at the last ZIG). Thanks to RVDM.
2745 Added some Object identifiers (RVDM).
2747 Changed the Update Extended Service (RVDM).
2749 Added command "refid" to client which specifies referenceId for
2750 the following requests.
2752 Implemented extended service handling for server. See ztest.c
2753 for an example as well as backend.h. New handlers are registerd
2754 in the Init handler.
2756 * Changed interface for sort in server.
2758 Added new members to statserv_options_block. It allows a server
2759 to read options from another source than just the command line. Thanks
2760 to Charles Woodfield.
2762 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2763 renamed to zboolean. Some C++ compilers complained about the name.
2765 Minor changes to gils.abs. Added index 's' (sort) on title
2766 and date/time-last-modified.
2768 --- 1.4pl2 1998/1/30
2770 Fixed bug in server library regarding inetd mode (-i). This bug
2771 was introduced by release 1.4.
2773 --- 1.4pl1 1998/1/29
2775 Added sort facility in client and backend server interface.
2777 Fixed problem with dependencies in Makefile(s).
2779 Fixed bugs for encoders/decoders of extended services and
2782 Implemented sub-tree feature for schemas. Sub-trees are
2783 referenced in *.abs-files. See explain.abs for an example
2784 of the use of this feature.
2786 Modified bib1.att; local attributes for ANY didn't include
2787 ANY itself (only affects use of the retrieval module).
2789 Fixed bug in plain SGML reader in function data1_read_node:
2790 tags with prefix "var" was incorrectly interpreted as variants.
2792 Added feature "sub-schemas" to enable references to - and definitions
2793 of - group of elements.
2795 * Removed member parent from type data1_element (in data1.h).
2797 Implemented function odr_nullval() that returns the value of
2800 * Removed member num_children from data1_node (in data1.h).
2802 Made NT service interface part of the server library. The
2803 function statserv_main uses the NT service when required and
2804 calls the statserv_start / statserv_close routines.
2806 Routine zget_SearchRequest and zget_PresentRequest fills
2807 resultSetName/Id member with "default" instead of "Default".
2809 Fixed memory leak in server. Request queue member wasn't freed.
2811 Fixed nmem_exit so that memory is freed.
2815 Revised the CCL parser utility to be thread safe.
2817 Added function, oid_ent_to_oid, to replace the function
2818 oid_getoidbyent, which is not thread safe.
2820 * Added nmem_init and nmem_exit to initialize and release
2821 NMEM resources. Function nmem_init should be called once in the
2822 initial thread before NMEM/ODR is used. statserv.c and client.c
2823 have been changed accordingly. The change was necessary to make
2824 NMEM thread safe. The NMEM memory pool is shared amongst threads
2825 in a process. Unix-based applications will still work fine without
2828 Added NT Services interface for the the Z39.50 (statserv) Server.
2829 Refer to the ztest.c source on the usage.
2831 Windows 95/NT port using MSVC5.0. Project files are included in the
2834 * Defined new 'global' handle for the retrieval (data1) system. The
2835 new handled, data1_handle, describes the state of the data1 system.
2836 This handle is passed as first argument to virtually all
2837 data1 related routines. The functions data1_create and data1_destroy
2838 creates and destroys a data1 handle respectively.
2840 Added ODR encode stream member to all backend request structures
2841 init, search, scan etc. This stream should be used to allocate all
2842 memory used for the response when thread safe operation is needed.
2844 Changed the comstack utility, cs_addstr, to be thread safe. The
2845 returned hostname string returned by the function is now part the
2848 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2849 function. The cs_straddr takes a COMSTACK handle as argument, so this
2850 function must be used after cs_create and before bind/connect.
2851 This function is thread safe.
2853 Moved test server to 'ztest' directory - generic server code still
2854 in 'server' directory.
2856 Made prefix query (pquery.c) utility thread safe.
2858 Added new function modifier YAZ_EXPORT to 'export' public DLL
2859 functions when using windows (see include/yconfig.h).
2861 Added definitions to the OID database (util/oid.c) (RVDM).
2863 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2865 Added call to ccl_rpn_delete in client program.
2867 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2868 release of RPN structure.
2870 Added support for C++, headers uses extern "C" for public definitions.
2871 With input from RVDM.
2873 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2874 Thanks to Ronald van der Meer (RVDM).
2876 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2878 Added support for private extensions to the OID database
2879 (oid_setprivateoids()). Thanks to RVDM.
2881 Added optional, physical ANY (key replication)
2883 Fixed null-reference problem in GRS-1 output filter.
2885 Proximity operator added to Prefix Query Format (PQF).
2887 In test client command "base" accepts multiple databases.
2889 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2893 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2895 Smallish bug-fixes in the new encoders/decoders (explain).
2897 Bug fixed in DeleteRequest.
2899 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2901 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2903 Added SOIF syntax (using private OID for now) to retrieval module and client.
2905 Added Update extended service.
2907 Added SearchResult-1 additional info structure.
2909 Added optional CCL (ISO8777) interpreter as separate module. Available
2912 --- 1.2 1996/6/10 (1st anniversary release)
2914 Added Summary record syntax. Lightly tested.
2916 Added OPAC record syntax. Untested.
2918 Added ResourceReport service encoders/decoders. Untested.
2920 Fixed bug in z_Unit - wrong tagging on unitSystem.
2922 Fixed bug in the DiagRecs decoder.
2924 Added options for max PDU size and session timeout to frontend-server.
2926 Added documentation of query-language parsers and other supporting utilities.
2928 [frontend-server] Added Attribute set to the bend_scanrequest API.
2930 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2931 surrogate diagnostics were generated.
2933 [retrieval] Allow multiple local values for attribute.
2935 [retrieval] Allow multiple attributes per element in .abs files. index type.
2937 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2939 --- 1.1pl2 1996/4/10
2941 Minor changes, mostly specific to Zebra's requirements (retrieval)
2945 Repaired bug in frontend server when running multiple listening
2946 endpoints in dynamic mode.
2948 z_External() now won't break if a known, ASN.1 value comes encapsulated
2949 in an octet-string. The value will pass through unmodified in an Odr_oct.
2951 Added a bit of code to the demo client to decode & display
2952 ASN.1-structured records represented in the octet-aligned branch of
2953 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2955 Added z_ext_getentbyref() to the ASN module. Doc updated.
2957 * Completed the SCAN definition in the ASN module. This may break SCAN
2958 code based on older YAZ-versions at compile-time. The fix is easy -
2961 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2962 under the SCAN definition. Remember to initialize this, server-people.
2964 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2965 that this does not extend to ODR and ASN.
2967 Comstack allows insertion of established socket (primarily for
2968 inetd-operation of servers). Doc updated.
2970 Front-end server can now start from the inetd in TCP mode. Doc
2973 --- 1.0pl4 1996/1/24
2977 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2978 the rank and record number.
2980 Adjustments to the frontend server.
2982 Fixed diagnostic BER dumper. It ignored the file argument.
2986 Various changes to retrieval module.
2988 Changed the union discriminators of the protocol files from enums to
2989 ints paired with #defines.
2991 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2994 *Changed operator in the RPN structure to 'roperator', again to avoid a
2997 Fixed problems in Explain decoders/encoders.
2999 --- 1.0pl2 1995/12/6
3001 Memory bug in log module fixed.
3003 --- 1.0pl1 1995/12/5
3005 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3007 Bug in Explain DatabaseInfo module fixed.
3009 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3013 The shift to v1.0 signals that we now consider the *core* functionality
3014 of YAZ reasonably stable (the core being more or less equivalent to
3015 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3016 tested (Explain not at all - though that will happen soonish).
3018 Minor changes to code to support Windows port.
3020 Various minor changes after we're getting to use GRS-1 & co. more.
3022 Added Espec-1 format.
3024 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3025 of the protocol and it cannot be selected when encoding (maps into 'string'
3026 when decoding). Needed to talk to some servers.
3028 Demo client can request simple element set names.
3030 Added Diagnostic Format encoders/decoders.
3032 Added simple Close handling to frontend server (no hooks for resource
3033 reporting yet), and demonstration client.
3035 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3037 --- 1.0b3 1995/08/24
3039 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3040 handled incorrectly when records were requested in the searchResponse. This
3041 will only affect you if you use the frontend-server.
3043 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3044 Test-client will ask for and print GRS1. Ztest will return dummy records
3047 Added Explain encoders/decoders to the service-level API. Untested.
3049 Added Extended Services: Item Order encoders and decoders to the Service-
3050 level API. Untested. We could use a recent copy of the pertinent bits
3051 of the ILL protocol to add those bits.
3053 Added diagnostic format 1 encoders/decoders to the service-level API.
3056 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3057 odr_cons.c, which causes a more correct output.
3059 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3060 was always set to 0 when no records were requested in the searchRequest.
3062 * Added better external-handling. This shouldn't harm old code that
3063 *encodes* externals. It can break code that looks for a
3064 'single-ASN1-type' representation, since those types that are known
3065 are now decoded immediately. Look at the SUTRS sample code in
3066 seshigh.c and client.c. Documentation updated.
3068 Handling of structured records in bend_fetchresponse. Length -1 marks
3069 structured record, type is deduced from format field.
3071 --- 1.0b2 1995/06/27
3072 Fairly quick maintenance release to add SUTRS support.
3074 Fixed handling of SUTRS records in the demonstration client.
3076 * Added format field to the bend_fetchrequest and bend_fetchresponce
3077 structures of the backend API (frontend server). When the record is
3078 returned, the value of the format field is mapped to an OID. The
3079 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3080 of the record. The special value VAL_NONE in the bend_request means
3081 that no specific format was requested by the client. Documentation
3082 updated accordingly. Test server (ztest) will return a fixed dummy
3083 SUTRS record if your client requests SUTRS.
3085 Documentation updated accordingly.
3087 You can now set external libraries and RANLIB support in the top-level
3091 First public release.
