3 Fix cql_sortby_to_sortkeys. Completely broken before.
5 Make CCL's @truncation work again.
9 New ZOOM connection setting: tproxy. It's like proxy, but does not
10 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
11 to set resolved address + port for a connection outside ZOOM itself.
13 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
17 Fix uninitialized variable in Solr spell support (could cause SEGV
18 for SRU response decoding).
20 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
21 back-end's addinfo through into the ZOOM response addinfo.
23 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
24 they are separated by a colon and a space rather than simply
29 Add support for Solr spell-checking/suggestions through ZOOM.
30 If a Solr target has been configured correctly for spelling-checking
31 and suggestions, these will now be returned on the ResultSet option
32 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
36 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
37 with a flag whether to substitute escape sequences or not.
41 Fix nmem_strsplit_escape to substitute escape char properly.
43 New option for zoomsh -e , which makes it abort on first error and
44 return process exit code to indicate success/failure.
46 YAZ options utility supports special option -- which makes all it treat
47 all following arguments as non-options.
51 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
52 searched if absolute filename is given.
54 Fix conv_xslt() error-reporting when stylesheet is not found.
55 (The value of fullpath is meaningless in this situation.)
59 Fix problem in CQL sort node creation: un-initialized memory.
61 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
62 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
63 CQL sortby depending on whether Type-1 or CQL is actually sent to the
66 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
67 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
69 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
70 will make it possible to use both single-character mask (#) and wildcard (?)
71 in CCL . Throw diagnostic for left truncation because that is not supported
76 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
77 cases using escapes (\-sequences) and masking.
79 PQF parse fix: A trailing backslash followed by end-of-string (\0)
80 would result in a read one byte beyond string.
82 rpn2ccl may use Z39.50 masking for terms (t=z).
84 ICU check fix. Don't include library -lCrun on Solaris, unless present.
86 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
87 not --cppflags (which seeems like an error in icu-config).
89 -- 4.2.12 2011/08/27 RPM package only
91 cql2ccl: fix conversion of terms: operator characters were not
94 -- 4.2.11 2011/08/25 RPM package only
96 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
97 CCL parser will map both # and ? to their regular expression
98 quivalents (. and .*).
100 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
101 of reserved CQL characters.
103 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
104 is, so that they are passed through.
108 ZOOM SRU mode: more aggressive re-connect.
110 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
111 made available as a utility function, declared in <yaz/logrpn.h>
113 rpn2cql_structure() supports proximity nodes (except that the Type-1
114 proximity node's "exclusion" binary is ignored, as there is no way to
115 express that in CQL). Fixes bug #4564.
119 Fix SEGV that could occur if set command of zoomsh was given without
120 value (2nd argument).
122 Fix SEGV that could occur if unsupported transport was given for
123 COMSTACK - say https (when SSL was unavailable).
125 Build yaz-url on Windows too.
129 New utility to get web content. Header is url.h. A command line tool
130 yaz-url is part of the distribution and packages.
132 Fixes for SSL COMSTACK (when gnutls is in use).
134 New functions yaz_base64{encode,decode}. Header is base64.h.
138 ZOOM C includes HTTP response buffer as additional info if it fails
139 to decode the SRU response.
141 Make wrbuf_json_puts available.
145 zoom: throw diagnostic for invalid value for option "sru". Before a
146 bad SRU request was sent.
148 Adding new utility wrbuf_vp_puts.
150 Add cclxmlconfig.obj to win/makefile. It was missing completely.
154 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
155 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
156 redirect was used at the same time.
158 MARC line mode decoding: be less picky about length given - first
159 5 digits of header that is.
161 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
163 Changes to decoding of SRU records: a record with recordPacking=xml is
164 modified with a new root element <yaz_record> if the recordData contains
165 multiple children elements. This is to make the record XML parseable
168 RPN to SOLR conversion: encode special characters.
170 Generic Frontend Server: fix uinitialized member, stepSize.
174 Fix a bug in SRU decoding of records.. The database records stored
175 had un-initialized memory, but it would only be seen with yaz_record_render
176 and type_spec="ext" .
178 Fix a bug in ccl_qual_dup introduced in 4.2.3.
182 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
186 Add new utilities to convert from CQL to CCL . These utilities have
187 prefix cql_to_ccl defined in cql.h.
189 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
190 lead to memory heap corruptions when ICU utilities were in use.
194 Make compilation work without Libxml2.
196 yaz-client: remove redundant blanks in display of searchResult-1 term
201 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
202 resulting CQL node (tree) in a new node CQL_NODE_SORT.
204 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
205 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
206 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
207 Note that the CQL sortby spec is only converted when the GFS is already
208 converting from CQL to RPN (cql2rpn element).
210 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
211 specify whether to collapse delimitors or not. The existing nmem_strsplit
212 do collapse (collapse parameter = 1).
214 Windows installer: For NSIS, set InstallDir depending on x86/x64.
216 Rename internal func yaz_use_attribute_create. While non-static, this
217 function is not declared in a public header.
221 Add -lCrun when linking with ICU on Solaris.
223 More quicks character set conversions for OPAC records.
227 fix problem with record_render: records were converted (character set
228 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
232 SRU: add methods for handling DADS SRU-proxy facets.
234 Separate OPAC record character set for ZOOM_record. yaz_record_render
235 allows a character set given as charset=from/opacfrom,to where 'from' is
236 the character set of a bibliographic record, 'opacfrom' is character set
237 of OPAC record and 'to' is the target character set.
241 yaz-client: show may XML format records. Command show followed by 'format'
242 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
245 src/stemmer.c: Avoid using unnamed union. It is not supported by some
248 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
251 Update yaz.spec to operate on both SLES11 / Centos 5.5.
253 RPM: Release includes 'indexdata' name. Use indexdata in release name so
254 this package can be distinguished from other vendors.
256 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
257 as determined by configure
259 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
261 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
262 returns no error and no record, the present request is considered
263 partial (only a subset of the records could be returned by backend), and
264 so it is appropriate to set Present Status to partial-4.
268 Move yaz-config man pages to section 1.
270 More documentation about SOLR.
272 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
273 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
274 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
275 peers on some Linux systems. However, in general that does not work
276 so YAZ can not rely on that to work. Debian changed behavior in this
277 respect from Debian lenny to Debian squeeze (still testing as of Oct
279 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
281 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
285 Fix yaz-config output: echo_source not set correctly by configure.
289 SOLR WebService support for yaz-client and ZOOM.
291 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
293 --- 4.0.12 2010/08/17
295 Z39.50 facet support. Facet specifications are passed for search in
296 other-information with ASN.1 as defined in facet.asn and OID
297 .10.1000.81.5 . Facets are expressed as an Attribute list as known
298 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
299 3 is limit (number of entries to get in response). yaz-ztest returns
300 dummy facets if a client asks for them.
302 --- 4.0.11 2010/07/09
304 CCL fixes: bug 2895 and bug 3539.
306 GR1-display: add comma in display - was removed by mistake in
309 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
311 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
313 --- 4.0.10 2010/06/18
315 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
316 result set from a connection. The result set will be on its own
317 thereafter; no operations on it will perform retrievals from a target.
318 Only cached copies are returned.
320 ZOOM C:fix case for HTTP servers responding with Connection:close.
321 Ensure that if there is a current task it is resumed (like fetching
322 more records in a result set) . Bug #3484.
324 PQF parser: use odr_atoi for Odr_int (not atoi)
326 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
327 values that contain any non-digits are treated as string attributes
328 (previously decoding only checked for leading character ([0-9]). PQF
329 encoding: attribute string values are not surrounded by double-quotes.
333 New utility for managing threads - thread_create.h.
335 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
336 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
337 but YAZ' implementation do.
339 Fixes for yaz_cond-functions on Windows 7.
341 DLL export more symbols.
343 zoomsh: show record do NOT render opac.
345 Remove *.la files from Debian and RPM packages.
349 Debian package libyaz-dev depends on libgnutls-dev again (was
350 removed in YAZ 4.0.6, but due to Libtool it is still needed
351 even though yaz-config do not list libgnutls libs).
353 ZOOM: Use only one WRBUF for returning string results for
354 ZOOM_resultset. Reduces memory usage for ZOOM in general.
356 ZOOM: ZOOM_connection do not use a shared pointer to
357 ZOOM_resultset after ZOOM_resultset is destructed by
358 user. Reverts to YAZ 4.0.4 behavior.
362 record-conv: fix problem with at least one XSL conversion -
363 due to probably incorrect usage of XML XSL documents.
367 Fix yaz-config for static mode and the use of SSL (gnutls).
371 Forward decl timeval struct in mutex.h and gettimeofday.h.
373 yaz-config: fix 'static' mode linking.
377 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
378 are wrappers for pthreads or Windows. For Windows these are put in
379 a separate DLL: yaz_cond4.
381 libyaz.la (whole source) is compiled with thread. If thread support
382 is enabled enabled, all source of YAZ is compiled with treading support.
383 This allows core utilities such as yaz_log to use thread facilities.
384 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
385 thread utilities. This commit moves mutex utilities (mutex.c) from
386 libyaz_server.la to libyaz.la.
388 yaz-json-parse displays leading text until error.
392 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
393 patch from Giannis Kosmas.
395 SRU: no longer URL encode SRU database. The URL for an SRU server is
396 a URL and such is alreeady encoded - at least when given with leading
397 http:// or https://. This reverts behavior to YAZ 3.0.50.
399 Support for new MARC XML notation TurboMARC which like MARCXML is a
400 complete representation of MARC/ISO2709.. This one, however, is more
401 compact and allows for faster processing with XSLT. TurboMARC can be
402 used in the marcdisp.h API, from the yaz-marcdump utility and from
405 yaz-ztest can be configured - via the database - to perform certain
406 delays when it performs operations search, present and single record
407 fetch. This allows testers to make yaz-ztest act as a real or even slow
408 Z39.50 server. Refer to the yaz-ztest man pages for details.
412 wrbuf_destroy allows NULL WRBUF passed to it.
414 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
416 Add ZOOM_connection_close.
418 No fixed size buffers for ZOOM shell - bug #3257.
420 tstodr: make it work on s390 platform.
422 New icu iterator-functions. The new icu_iter-functions makes it possible
423 to use ICU chains from many threads.
425 yaz-client: better syntax check for show command.
429 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
432 New simple local-file XML include facility which allows file glob-patterns.
433 Refer to yaz/xml_include.h.
435 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
438 ZOOM_record_get supports new parameter "format" which makes it format XML
441 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
442 JSONText in ECMA-262) is JSONValue, not JSONObject.
446 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
447 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
449 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
450 POSIX/Unix builds .so with major version 4.
452 Remove old LOG_-defines from log.h. They have been obsolete and
453 undefined by default for the last 5 years.
455 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
457 GFS: Remove socket (int *fd) from search_rr handler. The socket
458 descriptor ptr is a facility that allowed a search handler to supply
459 a socket which would serve as a callback - when search was complete.
460 This facility has now been in use for years.
462 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
463 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
464 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
465 returns 'const char *' rather than 'char *. The returned string is
466 read-only and should not be modified by applications. COMSTACK cs_close is
467 now a void function - it no longer returns int. No applications check for
468 the value and the implementations has always returned 0.
470 ZOOM: use size_t for scan hit counts and str size. Functions
471 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
472 occ (hit count) and len (string length) are now of type size_t pointer
473 rather than int pointer. This is to be able to represent large hit counts
474 and to also just to use the proper type for string length (strlen result).
476 New JSON parser. Refer to include/yaz/json.h .
478 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
479 Used to be int in some cases. Many wrbuf_-functions used to return an int
480 indicating some length.. These return values were never used. And so they
483 ODR: odr_malloc, odr_total now takes size_t for size.
485 clone_z_type: fix leak; occurred for encoding failures.
487 --- 3.0.52 2009/12/03
489 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
490 bug was introduced in 3.0.51.
492 --- 3.0.51 2009/12/02
494 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
496 tcpip comstack: fix leak for getaddrinfo.
498 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
499 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
500 Decoding of SRU "path" database is performed by private function
501 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
502 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
504 yaz-client: honor base command for SRU. Change when database setting
505 is applied for SRU and ensure it is kept when a connection is reset.
506 Change also the way errors are displayed or SRU (decoding of packages).
508 --- 3.0.50 2009/11/02
510 Add support for extra request / response data for SRU codecs and GFS.
511 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
512 for extra data response buffer and length. For the GFS, both request
513 and response data (XML) is carried in extra_args and extra_response_data
514 for the search handler. Patch by Ko van der Sloot.
516 ZOOM: For queries that cannot be converted to the specified rpnCharset,
517 ZOOM now returns a diagnostic on the client-side ('invalid query' /
518 10010). This fixes bug #2113.
520 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
521 cmdfile included a 'quit' command that would result in a memory violation.
523 --- 3.0.49 2009/10/01
525 Make a number of functions defined in xmlquery.c static. These have
526 never been declared in a public header file (yaz/xmlquery.h) and was
527 made public by mistake.
529 Improve speed of character conversions (iconv utilities). This makes
530 conversions from MARC-8 faster.
532 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
533 unless type desired is "raw". This will prevent type "xml" from
534 returning ISO2709 .. Which obviously can not be XML parsed.
536 Fix memory leak in ZOOM that would occur if option apdulog was used
537 on a re-used connection.
539 Frontend server logs HTTP requests.
541 Frontend server now sends Z39.50 close when it times out (sesssion has
542 been idle for too long). Versions 2.0.30 and earlier also sent close.
543 But due to a mistake this was disabled in all versions after that, i.e.
544 the server would just close the socket immediately.
546 yaz-client emits a better message when receiving an unrecognised
547 userInformationField.
549 Skip zero-length subfields when decoding ISO2709. This rare case happens
550 if a record has two FS characters in a sequence. Without this patch
551 there would be a reference beyond char array in using_code_len fragments
554 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
556 --- 3.0.48 2009/08/28
558 The show command offered by the zoomsh command now takes a 3d optional
559 parameter type which is what is passed to ZOOM_record. If the type
560 argument is omitted, "render" is used.
562 RPN to CQL conv may use USE string attributes (bug #2978).
564 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
566 --- 3.0.47 2009/07/08
568 Function yaz_xml2query allows a diagnostic element in the PQF XML
569 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
570 code and additional info respectively.
572 The BER BOOLEAN is now the integral type Odr_bool which still happens
573 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
574 typedef'd to Odr_int. This is still an integral 'int', but it may be
575 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
576 ASN-1 compiler as well as programs has been updated to use the new types.
578 --- 3.0.46 2009/06/08
580 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
581 only the bibliographic record was rendered. For type=opac, an OPAC
582 record is only returned if it is present.
584 iconv: small fix for encoding of advancegreek.
586 yaz-client: avoid double display of SRU/SRW records (bug #2798).
588 yaz-client: option auto_reconnect=on really reconnects.
590 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
592 server: avoid null ptr ref for for yaz_poll errors.
594 build: fix RPM build for RHEL 5.3.
596 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
598 --- 3.0.45 2009/03/31
600 Fixed bug #2709: TCP connect returns Invalid argument.
602 Fixed compilation for mingw.
604 Honor charset for raw records (ZOOM_record_get).
606 Fixed use of errno for threaded mode that was seen on Solaris 10.
608 Fixed argument passing with blanks in value for Windows Service.
610 Disable YAZ' own log rotate by default (no 1 GB limit).
611 The variable l_max_size which specifies the log file limit is set to 0
612 (DISABLED): This is due to the fact that YAZ is most often deployed using
613 logrotate. Also YAZ can not perform log rotate because of unsufficient
614 permissions (setuid).
616 --- 3.0.44 2009/02/17
618 List supported encodings in man page for yaz-iconv.
620 Fixed missing SSL libs for --libs output
622 Re-established OID record syntax application-xml. Nobody should use it
623 but we don't want to change soname because of this symbol being absent.
625 --- 3.0.42 2009/02/02
627 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
629 Added member named_result_sets for init handler struct for the GFS. This
630 allows a server to disable named result sets.
632 Removed OID record syntax application-xml.
634 Added support for rule-based transliterator for ICU wrapper of YAZ.
636 Fixed bug #1902: yaz-icu XML output.
638 Make YAZ checks Emacs friendly.
640 BITSTRING value shows value. Bug #2346.
642 ISO2709 decoding: skip control characters from indicator data.
644 Omit sort key by default in yaz-icu's output.
646 Allow combined single char options (again) for YAZ' options function.
648 Utility yaz-marcdump got option to display YAZ version (-V).
650 Allow YAZ to use ICU 3.4.
652 Added new ICU test case which illustrates removal of diacritics.
654 --- 3.0.41 2008/12/29
656 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
658 --- 3.0.40 2008/12/29
660 For configure, using option --without-xml2 also disables Libxslt/Libexslt
663 Fixed bug #2352: yaz-marcdump crashes for certain record.
665 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
667 Added support for Danmarc2 to UTF-8 conversion.
669 Added support for ISO5426 to UTF-8 conversion.
671 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
672 implementation version.
674 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
676 --- 3.0.38 2008/11/10
678 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
679 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
681 ZOOM C now interprets databaseName option for ZOOM connection as path
684 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
686 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
688 Dummy Libxml2 types no longer defined in headers of YAZ'.
690 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
693 --- 3.0.36 2008/09/26
695 Various ODR chapter fixes.
697 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
699 Added missing source for Windows compilation, mutex.c.
701 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
703 For SRU connections in ZOOM all records up to "count" are now fetched.
705 Fixed crash in generic frontend server (and yaz-ztest) which occurred
706 in Windows due to bad error handling for Libxml2.
708 Added facility for sending arbitrary records (ASN.1 any) using
709 ZOOM C's Extended service update. Patch by Sam Reynolds.
711 New options for ZOOM C's connection, logapdu which makes ZOOM log
714 --- 3.0.34 2008/06/18
716 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
718 --- 3.0.32 2008/06/12
720 Fixed memory violation that could occur when decoding UTF-8. This bug
721 was only present in 3.0.30 of YAZ.
723 --- 3.0.30 2008/06/06
725 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
726 GNU TLS is used by default (if found).
728 yaz-ztest returns OPAC records if a client asks for OPAC.
730 Improved speed of MARC-8 encoding.
732 Added support for lossy and loss-less MARC-8 encoding.
734 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
736 Added new Windows Service wrapper (sc).
738 yaz-client's itemorder command may now send a file.
740 Fixed yaz-marcdump to allow the use of NS prefix for record element.
742 Added new function yaz_log_xml_errors.
744 Allow (but warn) unknown XML attributes in MARCXML parsing.
746 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
748 The UTF-8 to MARC-8 conversion now uses a different set of characters
749 for Greek symbols. Bug #2120.
751 --- 3.0.26 2008/02/21
753 Added yaz_daemon (daemon.h).
755 Fixed bug #2068: pkg-config trouble
757 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
759 --- 3.0.24 2008/01/28
761 Document --with-xml2 option.
763 Added OPAC XML XSD (etc/opacxml.xsd).
765 Allow glob mask for name attribute in retrieval element for the
766 generic frontend server's retrieval facility.
768 Changed yaz_poll_poll to return yaz_poll_except for all returned events
769 except POLLIN/POLLOUT.
771 Fixed error handling in cs_listen. Bug #2037.
773 --- 3.0.22 2008/01/20
775 Fixed version in yaz/yaz-version.h.
777 Fixed bug #2027: Crash when closing connection.
779 Changed configure so that ICU support is only enabled if only ICU
780 and Libxml2 is available (because the ICU chain is XML based).
782 --- 3.0.20 2008/01/15
784 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
785 is built. Only this DLL depends on the ICU runtime.
787 yaz-ziffy is no longer part of YAZ. It is distributed separately by
788 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
790 Changed license of CCL module to 'Revised BSD'. After consultation with
791 remaining members of the original EUROPAGATE consortium, we are re-issuing
792 the CCL module without a separate license. The software was developed by
793 Index Data as part of a research project. The special license was included
794 to help feed usage information back to the project consortium to support
795 project evaluation. At this time, the project consortium has long-since
796 disbanded, and the majority of the original principals have retired. At the
797 same time, we have significantly modified the software during the following
798 years, to the point where very practically no original code remains. To
799 simplify re-use of the software, we have contacted those members of the
800 consortium who could be reached, and agreed to re-issue the module as a
801 proper part of the YAZ package.
803 Tcl scripts uses /usr/bin/tclsh as preferred shell.
805 CQL closer to being version 1.2 compliant. CQL also allows free-form
806 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
809 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
810 bug could make Extended services handling crash in the ZOOM layer. This
811 bug was only present in YAZ 3.0.18.
813 --- 3.0.18 2007/12/19
815 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
818 yaz-marcdump reads and writes collection wrapped records.
820 Handle OPAC for record conversion module.
822 Fixes for ICU wrapper.
824 Allow ICU libs to be controlled with --with-icu .
826 --- 3.0.16 2007/11/12
828 Added yaz_poll which is a wrapper for select/poll. When poll is available
829 and non-buggy, it is used, by yaz_poll . This allows more than 1024
830 sockets to be in use.
832 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
833 functionality through an XML based configuration (ICU chain). This system
834 is useful for search facilities such as Pazpar2 and Zebra that needs to
835 perform tokenization of indexed material. The ICU code in a separate
836 library libyaz3_icu.a.
838 Added HTTP tunnel facility for COMSTACK, bug #1752.
839 This is a facility that allows a Web proxy, such as squid, to tunnel
840 Z39.50 traffic. This facility is "transparent" to must applications
841 using YAZ. It's enabled by using pseudo transport connect: followed by
842 the proxy address, followed by command, then follwed by he regular
843 "virtual" addresss. For example,
844 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
846 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
848 --- 3.0.14 2007/09/21
850 Fixed bad memory reference in ZOOM_record - cuased by member not being
851 initialized. This was a problem only in YAZ 3.0.12.
853 Fixed bug in conversion from MARC to XML: Non-XML characters in control
854 fields were not removed.
856 Changed the way C code is generated from codetables.xml. Made a MARC-8
857 conversion trie for each characterSet section rather than codeTable.
858 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
859 of codetables.xml from Larry Dixson, LOC. Bug #1464.
861 --- 3.0.12 2007/09/12
863 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
864 from ZOOM_record_error).
866 ZOOM C function ZOOM_record_get returns record schema for type="schema".
868 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
870 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
872 Better SRW-to-Bib-1 diagnostic mapping.
874 ZOOM C and yaz-client announces SRU version 1.2 by default.
876 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
879 Fixed in yaz_sru_decode to allow other version than 1.1.
881 --- 3.0.10 2007/08/22
883 Added support for SRU scan for ZOOM.
885 Added support for the use of the older versions or Extended Service
886 Update in ZOOM. To faciliate this, an option "updateVersion" may be
887 set to the version , 1=first, 2=second, 3=third. The third version is
888 what ZOOM C has used so far. And that, obviously, is the default.
890 Added support for CCL queries in Z39.50 queries sent to the GFS (and
891 therefore in Zebra and in SimpleServer-based applications). The new
892 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
893 qualifier file used to transform incoming CCL queries into Type-1 RPN,
894 which is passed into the back-end search callback function.
896 Added support for HTTP Basic authentication in clients: the SRU/W
897 codec encodes the username/password elements of the PDU structure
898 appropriately, and these may be set using the "user" and "password"
899 options in ZOOM-C applications (the same options that are used for
900 Z39.50 authentication).
904 Fixed bug #1208: SSL appears to be broken in ZOOM.
906 Fixed bug #1206: Libxml2 include path weirdness.
908 Added oid_name_to_dotstring.
910 Allow elementSetName to be specified for ZOOM C record update.
912 Allow waitAction to be specified for ZOOM C based for Extended Services.
914 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
915 syntax OID. Bug introduced in YAZ 3 series.
917 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
921 Fixed bug #1157: yaz-client does not read .yazclientrc from current
922 directory. yaz-client now reads commands from file given by option -f
923 if specified; then tries to read .yazclientrc in current directory.
924 Failing that, it reads .yazclientrc from user's home directory.
926 Added support for correlationInfo Note and ID for Record Update via
929 Added yaz-client command querycharset which specifies character set for
930 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
931 (termListAndStartPoint).
933 Charset ISO5428:1984 is an alias for ISO5428-1984.
935 Implemented a way to perform scan in a result set using Z39.50. This
936 is achieved by attaching the result set name in the characterInfo
937 (type InternationalString) of OtherInformation in the Scan Request PDU.
938 The result set is identified in the otherinformation by the new OID:
939 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
940 This allows for scan in result set and faceted search . Zebra did some
941 of this in the APT term using attribute type 8 and value being result
942 set. Using the OtherInformation approach for this is cleaner and easier
943 to work with in proxies and the like. This facility can be used in
944 yaz-client using new command setscan which takes a result set as first
945 argument, start position (APT) as second.
947 Changed decoding of SRU XML packed records to deal with servers that
948 have recordData with XML data with multiple root nodes. Also make
949 comparison for recordPacking case insensitive. Again, one server
950 returns "XML" where others return "xml".
952 For SRU responses allow Content-Type application/xml as well as text/xml.
956 Fixed bug in character set conversion of BER strings. Bug introduced
961 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
963 For OID class, use oid_class consistently.
965 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
968 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
969 character set for bibliographic information interchange". By Giannis Kosmas.
971 Added documentation on new OID API.
975 Changes to generic frontend server interface: added new member
976 'query_charset' for bend_initrequest structure. A backend init handler
977 should set this member to its native character set for query terms.
978 When defined, the frontend server logic will announce this character set
979 to a client if the negotiationModel bit is set by the client. All server
980 implementors are encouraged to specify this. If a backend server does not
981 specify this a warning is issued using yaz_log(YLOG_WARN,..).
983 Added CCL utility to remove terms (stop words) from resulting RPN
984 tree. This is handled by functions with prefix ccl_stop_words_ .
986 New ZOOM C option, "rpnCharset", which allows client-side conversion of
987 terms in RPN queries.
989 Clean-up the CCL API. Moved some internal structures from ccl.h to
990 private header cclp.h. Changed ccl_parser_create so that a Bibset must
991 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
992 This is replaced by ccl_parser_find_str which takes a string instead.
994 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
995 libyaz.la is the core of YAZ except the generic frontend server and
996 does not depend on POSIX threads anymore. libyaz_server.la is the
997 generic frontend server facilities and uses POSIX thread functionality
998 if available. The libyaz.la no longer depends on POSIX threads because
999 the number of global structures is limited. NMEM no longer re-uses blocks
1000 between threads ; it simply free's memory immediately but allocates in
1001 "large" chunks as usual. We don't expect any performance penalties
1002 because of this. The yaz_log system is still using a global log_level so
1003 caution must be taken when modifying it with yaz_log_init_.. +
1004 yaz_log_mask_str. This, however, should not cause any trouble because
1005 these functions are called during initialization of application code
1006 anyway. `yaz-config --libs server` returns libs for server applications;
1007 `yaz-config --libs` returns libs for non-server applications.
1009 New OID database - with public definitions in oid_db.h. Removed old OID
1010 database including the head oid.h and definitions such as enum oid_value
1011 and struct oident. The new OID database uses the same string names as
1012 before but the 'protocol' is gone. There are now only two representations
1013 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1014 converts from string to OID; functions with prefix yaz_oid_to_string
1015 converts the other way.
1017 Change to emit_term() in CQL-to-PQF query translation: when a term has
1018 the /regexp relation modifier, do not process it for leading and
1019 trailing "^" and "*", which have quite different meanings in regular
1022 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1023 write handlers no longer carries a 'last' parameter. This will make
1024 yaz_iconv flush "less" characters. A flush is performed by call to
1025 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1027 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1028 removed, because function yaz_query_to_wrbuf does the same.
1030 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1031 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1033 Deprecated MARC utility functions removed.
1035 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1038 Branch split: YAZ_2_1_55_branch
1040 --- 2.1.54 2007/03/16
1042 Fix to ZOOM-C so that transparent reconnection is properly handled on
1043 connections that are in asynchronous mode.
1045 Fixed compilation on OpenBSD 4.0.
1047 Large strings in GRS-1 records are now properly displayed in yaz-client.
1049 Added character conversion support for "advancegreek"; based on patch from
1052 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1053 sequence is met. Before the error was not set so it would be unknown.
1055 Adjust yaz-marcdump MARC reader so that it skips until record separator
1058 --- 2.1.52 2007/03/07
1060 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1061 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1062 fd_set structure used as a bitmask for the FDs to be selected on.
1064 Using ACX_PTHREAD macro to check for POSIX threads.
1066 Fixed have-vsnprintf check.
1068 --- 2.1.50 2007/02/23
1070 Fixes for configure on BSD. Bug #900.
1072 Added snprintf/vsnprintf wrappers for systems that don't have
1073 limits (heavens forbid).
1075 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1076 created before all previous tasks were completed and removed from the
1077 task queue, the new task could be removed by a mistake.
1079 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1081 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1083 Fixed bug #832: Problem with MARC/charset in yaz-client.
1085 Fixed bug #668: save command line history for yaz-client.
1087 Fixed bug #830: pkg-config support.
1089 --- 2.1.48 2007/01/23
1091 Extended ZOOM result set options with two options that may be read by
1092 a client: resultSetStatus and presentStatus with values as specified for
1094 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1096 Fixed bug #827: Using SSL fails on Debian etch.
1098 Fixed bug #826: Weird looking chars for set of MARC records.
1100 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1101 that is treated as an ItemOrder with itemRequest being an XML document
1102 external. The value of "doc" is the content.
1104 Extended the GFS search facility. New member of bend_search_rr
1105 'estimated_hit_count' signals that hits is known to be an estmate
1106 (higher or lower than real hit count). New member 'partial_resultset'
1107 signals that the search was partial (hit count is lower or equal than
1108 real hit count). For Z39.50, the information is stored in resultSetStatus
1109 member of SearchResponse APDU. For SRU, the information is signalled
1110 via SRU diagnostic 59: "Result set created with valid partial results
1113 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1115 --- 2.1.46 2007/01/13
1117 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1119 Added ZOOM_connection_peek_event.
1121 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1122 the following new functions:
1123 ZOOM_event_nonblock, ZOOM_connection_process,
1124 ZOOM_connection_get_{socket,mask,timeout},
1125 ZOOM_connection_fire_event_{timeout,socket}.
1126 The existing blocking event handler, ZOOM_event, is a wrapper for the
1127 + blocking ZOOM_event_sys_{poll,select}.
1129 Implemented function ccl_xml_config which parses XML version of CCL
1130 configuration (bug #798).
1132 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1134 Added timings utility (yaz/timing.h)
1136 --- 2.1.44 2007/01/03
1138 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1141 Fixed bug #779: Rotation of apdu.log fails.
1143 Fixed for character set conversions:
1144 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1145 Honor G1 set in MARC-8 decoding.
1147 --- 2.1.42 2006/12/17
1149 Fixed bug #775: char conversion does not handle Alternative UTF-8
1152 Implemented function yaz_marc_read_line which parses MARC line format
1153 records. There is a wealth of formats out there. So far, this function
1154 reads line records produced by yaz_marc_write_line.
1156 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1157 more generic and easier to remember(!) options: -i format and -o format
1158 which specifies input format and output format respectively - where
1159 format is one of "marc", "marcxml", "line", "marcxchange".
1161 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1162 does not print anything except warnings for records.
1164 For yaz-marcdump, added support for MARC split into files (-s) with a given
1167 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1168 spec, at http://www.loc.gov/standards/sru/record-update/
1169 This has changed the binary layout of the following structs:
1170 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1171 bend_update_rr . Patch by Ko van der Sloot.
1173 Added GFS utility function bend_assoc_is_alive which returns 1 if
1174 association is still alive (client is connected); 0 otherwise (client
1175 closed connection). This allows busy servers to stop working for
1178 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1179 been a separate piece of software. This version of ziffy has been modified
1180 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1182 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1184 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1185 Client code may now interrogate options such as "init_opt_sort" to
1186 find out whether the server claims to support various options.
1188 --- 2.1.40 2006/11/27
1190 Added utilities yaz_{set,get}_esn to set/get element set name from
1193 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1194 of YAZ and has been so since YAZ 2.1.10.
1196 Implemented ZOOM_record_error which returns error information for
1197 record (surrogate diagnostic).
1199 --- 2.1.38 2006/10/31
1201 Updates for SRU Update by Ko van der Sloot:
1202 1. Changed name from "operation" to "action"
1203 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1204 versions in the code, marked as 'backward compatible'.
1205 3. Added diagnostics for SRU Update.
1207 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1209 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1211 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1213 For GFS, fixed problem with SRU diagnostic 'First record position out of
1214 range' being issued for 0 hits.
1216 zoomtst10 part of Windows Build.
1218 --- 2.1.36 2006/10/13
1220 Implemented yaz_filepath_comp which splits a path into file path
1221 components (required by Zebra 2.0.3+).
1223 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1224 BSD inspired license until now so this should not have any real impact on
1225 anybody. See http://www.opensource.org/licenses/bsd-license.php
1227 Fixed bug #687: Missing log lines.
1229 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1232 Fixed bug #689: SRU diagnostics to be added.
1234 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1235 whether a connection is idle (no more work do do).
1237 --- 2.1.34 2006/10/04
1239 Change type of optval from long to int for invocation of setsockopt with
1240 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1242 Added support for specifying the max log file size for the Generic
1243 Frontend Server. The size is given with option -r.
1245 --- 2.1.32 2006/09/21
1247 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1249 --- 2.1.30 2006/09/17
1251 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1254 Fixed bug in Generic Frontend Server that could cause a server to stop
1255 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1257 For the generic frontend server, the maximum record size is used as maximum
1258 size of incoming packages (SRU + Z39.50). The value until was previously
1259 only used in Z39.50 Init negotiation and, later, in a session controlled
1260 sizes of records returned. This is controlled using -k option. It can be
1261 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1263 --- 2.1.28 2006/09/04
1265 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1268 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1270 New option for yaz-marcdump -lpos=value which allows setting a portion
1271 of MARC header to a certain value.
1273 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1275 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1276 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1278 --- 2.1.26 2006/08/15
1280 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1283 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1285 --- 2.1.24 2006/08/08
1287 Fixed MARC ISO2709 encoding routines to deal with character set
1290 Minor changes to GFS logging. Database included in search request log
1293 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1294 cached/multiple records.
1296 Shared libraries are built by default on Unix+configure.
1298 Changed cql2pqf transformation to use a different evaluation order. The
1299 new order is: always, relation, structure, position, truncation, index
1300 and relationModifier. Old order was: always, relation, relationModifier,
1301 structure, index, position, truncation. Note that the the latter ones
1302 override former ones for identical attributes.. The new scheme means that
1303 it is possible to override any existing attribute with a relationModifier.
1304 And also that it is possible to override everything for the index rule
1305 (except the ones listed in relationModifier). No order is perfect but this
1306 one, we believe, covers more real cases.. The "always" should have been
1307 called "default", since the attributes there can be overridden with all
1310 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1311 compilation phase, but also for yaz-config --cflags output. This allows
1312 us to have public headers with Libxml2 stuff in them . It should also,
1313 eventually, make Libxml2 checks redundant in packages using YAZ, such
1316 --- 2.1.22 2006/06/15
1318 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1319 stored in uri, message and details.. Previously diagnostics were stored
1320 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1321 compatibility.. but he's probably the only one affected, so.
1323 Added support for CCL, compiled on the client side, in ZOOM-C. This
1324 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1325 input; the resulting query objects can be used for for searching with
1326 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1328 YAZ' configure searches for OpenSSL by default.
1330 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1331 SL_CTX_use_certificate_file. See
1332 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1333 for more info. Thanks to Ko van der Sloot.
1335 --- 2.1.20 2006/06/02
1337 Bug #600: SRU GET, POST support for yaz-client. Introduced
1338 command 'sru' which selects method SOAP/GET/POST.
1340 Allow missingValueAction to be specified for the sortspec string -
1341 function yaz_sort_spec. By default, the missing value action is null.
1342 Use ! to specify "abort". Use = followed by stringvalue to specify default
1345 Ensured that Present-handler (if defined) is called in GFS before any call to
1346 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1347 searchRetrieve requests.
1349 Documentation for YAZ is now based on the Docbook XML/XSLT using
1350 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1351 is no longer depending on jade/openjade or docbook-to-man scripts.
1352 PDF is no longer part of the distribution - but can optionally be
1353 made using DSSSL/jadetex or FOP.
1355 Added retrieval handling support in Generic Frontend Server to support
1356 conversion between MARC/XML as well as XSLTtransforms. See
1357 etc/yazgfs.xml for an example.
1359 Added Authentication support to Generic Frontend Server in SRU
1360 mode. Authentication using HTTP Basic is supported, as is the use
1361 of 'x-username' and 'x-password' parameters in the request itself.
1363 Added support for a new character set MARC8s identical to MARC8 except
1364 that it converts combined characters to single Unicode characters in the
1365 Latin-1 range (when possible).
1367 --- 2.1.18 2006/04/24
1369 ASN.1 compiler 0.4: generates brief Doxygen file header for
1370 generated .h/.c files.
1372 Utility yaz_iconv now supports conversion to MARC-8.
1374 New facilities for the MARC module. The reading - and writing of
1375 content are separate methods for the yaz_marc_t handle. The following
1376 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1377 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1378 format). Write functions have prefix yaz_marc_write_.. The existing
1379 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1380 available. Removed support for OAI-MARC and simplexml (not the
1381 simplexml from PHP5).
1383 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1384 to be returned for this connection.
1386 --- 2.1.16 2006/03/31
1388 Allow multiple languages and charsets to be specified with
1389 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1390 negcharset iso-8859-1,utf-8
1392 Translation of proximity nodes from CQL into PQF now works.
1394 Moved to automake 1.8, 1.9.
1396 Added function yaz_log_set_handler which allows a log handler to be
1397 installed. This handler will be called for all log messages. Output
1398 to file is also produced; but that can be disabled by passing NULL
1399 fname to yaz_log_init_file.
1401 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1403 For SRW (including GFS), accept application/soap+xml as content-type
1406 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1407 produces NO stylesheet reference even if a default stylesheet is specified
1410 --- 2.1.14 2006/03/14
1412 Updated Windows package to include yazd.dll + yazd.lib for the
1413 Development component.
1415 If the environment variable YAZ_LOG is set, then it is used as a
1416 string indicating the default level of logging to use if not
1417 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1418 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1419 used as before. So, for example, to omit warnings from YAZ logging,
1420 export YAZ_LOG=-warn
1422 cql_transform() now map structure and other attributes before indexes,
1423 so that index-specific structures and other attributes can override
1424 defaults. So now a combination of mapping specifications such as:
1426 index.dc.date = 1=date-modified 4=5
1427 does the right thing.
1429 cql_transform() now also respects the "always" mapping specification,
1430 which establishes an initial set of attributes to be used for all
1431 terms except where overridden by more specific attributes associated
1432 with the index, relation or modifier.
1434 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1435 which mode to use; one of "post", "get" or "soap" (SRW, default).
1437 Fixes for yaz_iconv routines: changed trie-based character set conversions
1438 to use only non-negative values for bit fields due to Sun's C compiler not
1439 supporting negative values.
1441 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1442 sequences where not read correctly. Fix by Rustam Usmanov.
1444 Updated win/makefile to use options, settings which makes things
1445 compile with VS C 2005.
1447 --- 2.1.12 2006/02/01
1449 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1451 In ZOOM socket code, use select instead of poll on MacOSX.
1453 ZOOM-C now support client-side compilation of CQL into RPN that is
1454 sent to the server, enabling CQL to be used against all Z39.50
1455 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1456 ZOOM_query object, and submit it using ZOOM_connection_search().
1457 The CQL-to-RPN translation uses a configuration file, the name of
1458 which must be specified in the Connection's "cqlfile" option.
1460 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1461 function, which takes as its start-term parameter a ZOOM_query object
1462 (which may have had either CQL or RPN set into it).
1465 --- 2.1.10 2005/11/29
1467 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1468 GFS to support this as well. Backend handler, bend_srw_update, does the
1469 update work. Code contributed by Ko van der Sloot.
1471 Allow retrieval of Search Result-1 information in ZOOM by the use of
1472 options that are attached to a result set. ZOOM documentation updated
1475 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1476 UTF-8 conversion. Patch by Raj Patel.
1478 Added option -m to GFS to control formatting of timestamps in log file.
1480 Added 'exit' as synonym for 'quit' in yaz-client
1482 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1483 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1484 for the new members. Patch by Ko van der Sloot.
1486 Added support for SRU POST. It is supported for content-type
1487 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1489 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1490 Instead make the library libyaz.la multi-threaded. Threading as a whole
1491 can still be disabled by configure option --disable-threads. Previosly,
1492 with older GLIBCs there were problems with MT libs under Apache. This
1493 has now been fixed a long time ago.
1495 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1498 CQL module modified to be case insensitive for relations/indexes/operations.
1500 Fixed bug in CQL transform code: incorrect value relationModifieder
1503 Added 'show all' command for yaz-client which retrieves all results
1506 Added new yaz-client, xmles, which takes a (private) OID and
1507 a document to be sent as an extended service request.
1509 Describe new yaz-client commands wait_response and set_auto_wait.
1511 Increase TCP/IP listener backlog from 3 (which I am guessing was
1512 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1513 that the socket will queue as many incoming connections as it's able
1514 to handle ongoing connections. In other words, it will never now
1515 refuse a connection that it would be able to handle merely because
1516 it's not got around to accepting() enough of the pending connections
1517 yet. This is the behaviour anyway under Linux, where the listen()
1518 argument is ignored; but not under BSD and on systems such as
1519 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1520 YAZ-based servers should now be uniform across operating systems in
1523 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1524 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1525 This allows yaz-marcdump to read large MARC batches (>2 GB).
1527 Modified all YAZ source files - except the source which is auto-generated
1528 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1531 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1532 corresponding to the existing *_setl() function. These allow option
1533 values containing arbitrary valuues.
1535 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1536 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1537 except that it returns an indicator of whether or not the sort
1538 criterion was accepted (0 for OK, -1 for invalid).
1540 --- 2.1.8 2005/06/07
1542 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1543 MARC output rather than returning "new" buffer.
1545 yaz-client warns about unknown init options.
1547 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1549 --- 2.1.6 2005/05/24
1551 Added support for SRW sort in Generic Frontend Server. Patch
1552 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1553 sortKeys - or NULL if none is provided.
1555 Fixed bug #307: It was impossible to specify indefinite/no timeout
1556 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1559 Added support for multiple languages and charsets to be specified in
1560 ZOOM. Each charset/language is separated by a blank. If negotiation is
1561 in effect in init-response, Option
1562 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1563 Code based on patch by Vasiliy Osadchuk.
1565 Fixed bug #306: infinite recursion that occurred when calling
1566 yaz_log_level_init as the first call (before other log level or
1569 Fixed bug in scan handling in front end server: if preferred-Position-In-
1570 Response was non-present, a NULL pointer referece was performed.
1572 --- 2.1.4 2005/04/26
1574 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1575 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1576 now defined for all those error codes. So instead of putting 109 in
1577 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1578 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1580 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1583 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1585 Program yaz-client now exits and produces an error message if multiple
1586 Z39.50 servers are specified on the command line (none or one allowed
1589 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1592 --- 2.1.2 2005/03/16
1594 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1596 Fixed bug #272: Preserve spacing for CCL terms.
1598 --- 2.1.0 2005/03/14
1600 Added support for virtual hosts and multiple backend servers for
1601 the YAZ frontend server. The configution is XML based and
1602 support specificition of CQL to RPN mappings and explain information.
1603 See section "Virtual Hosts" in the YAZ manual.
1605 Extended OPAC display utility. OPAC display utility renders
1606 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1607 to supplement yaz_marc_decode_wrbuf.
1609 Fixed a bug in MARC decoder that could caused it to crash for some
1610 invalid MARC records. More diagnostics and warnings where added in
1611 XML output (warnings, etc are stored in comments).
1613 --- 2.0.34 2005/02/08
1615 Fixes for UNIX domain sockets. Bug #261.
1617 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1619 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1620 Added yaz_marc_subfield_str which defines subfield lead string which is
1621 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1622 yaz_marc_endline_str which defines end of fields string used in
1623 YAZ_MARC_LINE format. Default string is newline.
1625 Experimental support for MarcXChange. This format can be produced
1626 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1627 http://www.bs.dk/standards/MarcXchange.xsd
1629 Added yaz-client commands scansize that sets maximum number of
1630 entries to be returned by scan.
1632 --- 2.0.32 2005/01/11
1634 Added support for SRW scan in yaz-client and Generic Frontend Server.
1636 * Added whereInList member to SRW Scan Term.
1638 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1640 Fixed NMEM system to return aligned blocks on the smallest boundaries
1641 that are suitably aligned for all possible types on the particular
1642 architecture YAZ is being built for.
1644 --- 2.0.30 2005/01/04
1646 Fixed numerious warnings that was issued with newer versions of GCC.
1648 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1649 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1652 Make YAZ Generic Frontend Server slightly faster.
1654 Enhance (and reduce) logging for Generic Frontend Server.
1656 Revert YAZ log system so that it flushes every write operation
1657 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1659 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1660 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1661 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1662 will effectively disable old definitions.
1664 --- 2.0.28 2004/11/09
1666 Added yaz_log_time_format which specifies log format using
1669 Added yaz_log_module_level which returns mask for a module. Value
1670 is non-zero mask a if module is enabled; zero if disabled.
1672 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1673 in include/yaz/cql.h.
1675 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1677 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1679 Fixed bug #172: RPM builds does not enable SSL.
1681 Doxyfile.in part of dist. Doxyfile generated by configure.
1683 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1684 are given and the corresponding component does not exist.
1686 Extend CCL documentation in YAZ reference. Describe r=r.
1688 --- 2.0.26 2004/10/01
1690 Fixed MARC->MARCXML conversion to properly deal with
1691 fields, subfields, indicators having non-ASCII characters.
1693 Fixed MARC->MARCXML conversion so that ASCII control characters
1694 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1697 Added YAZ GFS support for conversion from Z39.50 surrogate
1698 diagnostics to SRW surrogate diagnostics.
1700 Bug fix: YAZ GFS did not return schema in explainResponse.
1702 --- 2.0.25 2004/09/30
1704 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1705 now converts recordSchema to elementSetName as well as schema URI.
1707 Fixed bug in COMSTACK that prevented HTTP request packages from being
1710 --- 2.0.24 2004/09/29
1712 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1713 does not require white-space before and after the dash in a range, e.g.
1714 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1717 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1718 due to new GCC removing "redundant" code.
1720 Added yaz-client commands scanpos and scanstep that sets preferred
1721 position and step-size for scan.
1723 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1725 Added CCL utility ccl_qual_buf which parses one or more CCL
1726 spec lines in a buffer.
1728 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1729 of name and value - ignoring empty lines and comments.
1731 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1733 Added odr_get_element_path which returns current element path for an
1734 ODR handle. This utility is useful in error handling or user-defined
1737 Added ODR_PRINT utility odr_set_stream which is is a more generic
1738 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1739 to a write function and pointer to close function. The close function - if
1740 non-NULL - will be called during odr_destroy.
1742 Fixed bug in CCL parser where truncation char was not removed from
1743 right side when truncation=both was in effect.
1745 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1748 --- 2.0.23 2004/08/11
1750 Fix buffer overrun in CQL parser when dealing with proximity (%).
1752 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1753 to UTF-8/UCS conversion is now only based on codetables.xml.
1755 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1757 --- 2.0.22 2004/08/06
1759 Add support for more "commit changes" in ZOOM (uses Extended Services).
1761 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1764 Yet another small fix for configure of SSL.
1766 --- 2.0.21 2004/05/14
1768 Fix SSL libs for configure when --with-openssl=DIR is given.
1770 --- 2.0.20 2004/05/10
1772 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1774 SSL comstack now uses yaz.pem certificate file on server side
1775 by default. Certificate filename can be configured by calling
1776 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1778 Fix bug regarding multiple calls to ZOOM_connection_connect.
1780 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1782 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1783 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1785 ZOOM now allows inspection of X509 peer certificate for verification.
1786 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1788 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1789 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1790 as "modular" but it simplifies things.
1792 Added cs_get_peer_certificate to that returns peer X509 PEM.
1794 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1795 NULL if SSL is unavailable.
1797 Documentation about MARC decoding tools.
1799 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1801 --- 2.0.19 2004/03/30
1803 Rename CHANGELOG to NEWS to follow GNU style packing.
1805 Fix bug with missing initialization of member in init_diagnostics.
1806 This bug affects threaded version of GFS server.
1808 --- 2.0.18 2004/03/20
1810 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1813 Ensure zlib.dll is packed with Windows install.
1815 --- 2.0.17 2004/03/17
1817 Fix encoding of xsd:string to use text instead of CDATA.
1819 Fix endless loop in CQL parser with unbalanced ".
1821 Use a more compact way to store MARC-8 conversion tables.
1823 --- 2.0.16 2004/03/16 Debian only
1825 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1828 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1833 --- 2.0.15 2004/03/01
1835 Another fix for decoding of XML packed records.
1837 --- 2.0.14 2004/02/25
1839 Fixes for Chunked encoding. White space not ignored after length spec.
1841 Update NS and use default NS for SRW diagnostic elements.
1843 --- 2.0.13 2004/02/23
1845 Implement ZOOM_resultset_cache_reset which resets record cache.
1847 Implement ZOOM_resultset_sort which sorts a result set.
1849 Implement chunked HTTP transfer.
1851 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1853 --- 2.0.12 2004/02/16
1855 Added member 'schema' to bend_explain_rr structure so that backend
1856 can specify explain record identifier. Defaults to Zeerex 2.0.
1858 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1860 --- 2.0.11 2004/02/16
1862 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1865 Added init command for yaz-client which sends "extra" init request.
1867 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1868 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1870 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1872 Make ZOOM error code for "invalid query".
1874 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1876 --- 2.0.10 2004/02/05
1878 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1881 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1883 Added option -p <file> to make Generic Frontend Server to write PID file.
1885 Added option -D to put Generic Frontend Server in background on its own.
1887 Make ZOOM C recognize option "password". If unset, "pass" is used
1888 (for backwards compatibility).
1890 Fixed a bug in Generic Frontend Server that could make it crash if a
1891 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1894 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1895 Must be issued before open, in order to be in effect.
1897 --- 2.0.9-6 2004/01/12 Debian/Windows
1899 Make the SRU server more picky WRT unknown params, etc.
1901 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1903 New YAZ client command, options, that sets Z39.50 options.
1905 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1906 options from a string of tokens (one token for each option bit).
1908 Update SRW diagnostic code messages.
1910 --- 2.0.9-5 2004/01/07 Debian/Windows
1912 Handle user defined stylesheet for SRW/SRU.
1914 --- 2.0.9-4 2004/01/06 Debian/Windows
1916 Fix bug in decoding of Content-Length.
1918 --- 2.0.9-3 2004/01/06 Debian/Windows
1920 Fix a bug with decoding of XML packed records.
1922 --- 2.0.9-2 2004/01/05 Debian only
1924 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1926 Fix bug in SRW/SRU diagnostics decoding.
1928 --- 2.0.9 2004/01/05
1930 Fixed bug in Generic Frontend Server which could drop records exceeding
1931 preferred message size. Reported and fixed by Irina Dijour.
1933 Fixed calculation of package size for structured records in Generic
1934 Frontend Server. Reported and fixed by Irina Dijour.
1936 Fixed namespace for SRW/SRU diagnostics.
1938 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1940 --- 2.0.8 2003/12/22
1942 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1943 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1946 CQL changes to reflect recent changes to the specification:
1947 * Documentation talks about context sets instead of index sets.
1948 * Documentation talks about indexes instead of qualifiers.
1949 * The CQL-to-PQF transformer's configuration file now uses
1950 "index.set.name = <attributes>" instead of the old form
1951 "qualifier.set.name = <attributes>". (Both forms are still
1952 understood but the latter is deprecated.)
1953 * CQL terms with no explicit index specified are now interpreted as
1954 cql.serverChoice instead of srw.serverChoice (which of course
1955 behaves exactly the same.)
1957 --- 2.0.7 2003/12/16
1959 MARC conversion can now generate ISO2709 output in another
1960 character set. yaz-marcdump uses this facility if you invoke it
1963 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1964 functions from there can be used from C++.
1966 --- 2.0.6 2003/12/04
1968 Frontend server now transfers memory from decoded packages to stream
1971 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1972 references to show up.
1974 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1975 the ZOOM Abstract API. The older names for the same options are still
1976 also supported for the benefit of old applications.
1978 ZOOM-C supports "implementationId" and "implementationVersion" options
1979 to go along with "implementationName". These allow the user code to
1980 specify identification strings to be sent to servers.
1981 Add OID for the new ExtLite attribute set.
1983 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1984 as requested/supplid by Ere Maijala <ere@atp.fi>
1986 For generic frontend server, reverse the order of
1987 "toolkit-supplied / application-supplied" strings sent as implementationId,
1988 Name and Version. Also, remove the spaces around the slash. This brings
1989 the GFS in line with the behaviour of ZOOM-C on the client side.
1991 Add function ZOOM_scanset_display_term.
1993 yaz-client shows scan displayTerm if present.
1995 Utility yaz-iconv is now installed by default along with the man page
1998 Extend configure check for OpenSSL to use pkg-config where available (such
2001 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2002 server to specify uid/gid/mask for socket using the format
2003 unix:[user=uid,][group=gid,][umask=mask,]file=path
2004 If file= is omitted the existing format is assumed, e.g.
2006 in which case the mask is 0666 (rw for everybody).
2008 Major restructure of YAZ source. All source in libyaz is in src directory.
2009 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2010 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2012 Added man page for utility yaz-marcdump (used to be called marcdump).
2013 yaz-marcdump is installed by 'make install'.
2015 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2016 of incoming package failed.
2018 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2020 Change prototype of odr_perror: add const to message string.
2022 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2024 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2025 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2026 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2027 DNS lookup. There should not be any compatibility problems with this
2028 assuming that blocking=1 or 0 is used.
2030 Fix bad reference in UNIX comstack in function cs_addrstr.
2032 Fix for compilation on AIX.
2034 The generic front-end server (server/seshigh.c) now supports returning
2035 Init diagnostics to the client in User-information-field, in
2036 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2039 --- 2.0.4 2003/09/04
2041 Allow any CQL relation (not just all,any,exact,scr).
2043 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2044 that features the same UI.
2046 Implemented command update0 in YAZ client which is equivalent to
2047 update but uses old of Ext Update ASN.1.
2049 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2050 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2051 Previously no OID was used for this info.
2053 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2054 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2055 returns 'malformed search term' otherwise.
2057 SortResponse member resultCount now set to NULL in sort handler of
2060 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2063 Add three new utility functions for translating OIDs between various
2064 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2065 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2066 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2067 char *oid_to_dotstring(const int *oid, char *oidbuf);
2068 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2070 Reverted modifications for ES Update definition for z_IU0Update
2071 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2072 is back to YAZ 2.0.2.
2074 String value attributes for CCL parser.
2076 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2077 which their FirstSearch server returns in Init responses, sometimes
2078 carrying useful diagnostic information when Init fails. This has the
2079 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2080 "z39.50/oclcui.asn", where its definition is somewhat different from
2081 what OCLC document on their web-site, as required to interoperate with
2084 Support for anonymous authentication in yaz-client. Use the command
2087 * Fix the OID of the Index Data-local "admin" Extended Service from
2088 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2089 the 1000, which indicates a locally-defined OID, was a mistake.
2091 --- 2.0.3 2003/06/20
2093 Fix CCL directive @case handling so that it affects string match for
2094 both CCL keywords and qualifiers.
2096 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2097 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2098 Decoder has been updated with ASN.1 changes as listed in
2099 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2100 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2101 z_IUUpdate, remains unchanged.
2103 ZOOM_record_get may now return a record in a specific character set.
2104 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2105 "from" is the character set of record as returned by target. "to" is
2106 the character set to be returned. If omitted, "to" is UTF-8.
2108 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2110 New ODR utility, odr_getelement, which returns name of element for
2111 which encoding/decoding failed.
2113 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2114 in cases where a required element was omitted.
2116 Bug fix: some MARC8 sequences were not converted.
2118 New ZOOM option "step" which specifies number of records to be
2119 retrieved in one chunk. Used in conjunction with "start" and "count".
2121 SRW support for yaz-client. Use scheme http: to use it, e.g.
2124 yaz-client no longer does (un)intelligent character set conversions
2125 by default. Can be enabled with charset and marc_charset commands.
2127 xmalloc trace fix for 64-bit systems such as DEC alpha.
2129 Solaris 2.6 compile fix.
2131 New function, cql_strerror() translates SRW error codes, as returned
2132 by cql_transform_error(), into human-readable English strings. Used
2133 in yaz-client diagnostics when appropriate.
2135 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2136 converts it into a type-1 query which is sent to the server. This
2137 makes CQL available for use with all Z-servers, as opposed to the tiny
2138 minority that can handle CQL queries themselves.
2140 --- 2.0.2 2003/04/28
2142 New Debian package layout similar to the Redhat Package layout.
2144 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2145 and search result respectively.
2147 --- 2.0.1 2003/04/25
2149 Redhat package is now several packages: libyaz (runtime libraries),
2150 libyaz-devel (development and documentation, and yaz (utility programs).
2151 Package spec file by Morten Bogeskov.
2153 New member 'schema' in struct bend_fetch_rr which the name of requested
2154 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2155 handler MAY set this to reflect the schema of the returned record.
2157 New member 'display_term' in struct scan_entry. GFS now sets member entries
2158 and allocates scan entries to be filled by user scan handler. In previous
2159 version, entries member was allocated by the scan handler. That still works,
2160 but the GFS will ignore member display_term - assuming it was NOT set by
2161 the handler. The fact that the GFS now allocates the entries both allows
2162 for new members and makes a scan handler easier to write.
2164 Fix CQL lex buffer overflow.
2166 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2167 SRU default recordPacking is string.
2169 SRU protocol support for frontend server.
2171 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2173 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2175 Added scan for the ZOOM shell (zoomsh).
2179 * String Identifers for Schemas (Amendment 5).
2180 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2181 Old definition for schema
2182 Odr_oid *schema; /* OPT */
2187 Z_InternationalString *uri;
2188 #define Z_Schema_oid 1
2189 #define Z_Schema_uri 2
2192 * resultCount parameter to Sort Response (Amendment 1).
2193 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2195 Support for SRW 1.0 over HTTP. This is an optional feature and
2196 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2199 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2200 on the same port. SRW SearchRetrieveRequests are mapped
2201 to bend_init,bend_search,bend_fetch,bend_close.
2203 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2205 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2206 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2208 ZOOM connections are SRW based if schem http is used for hostname
2209 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2210 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2212 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2213 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2214 distance=n, order=true/false, relation=le, prox unit=word. If
2215 n is omitted, distance 1 is used.
2217 Fixed problem with C compiler include path in wrong order.
2219 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2220 on Solaris. Patch from Ko van der Sloot.
2222 New MARC decode API. All new functions operate on a yaz_marc_t
2223 handle. The most important new functions are: yaz_marc_create,
2224 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2225 decode and destroy respectively. Decoder can produce formats
2226 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2227 include/yaz/marcdisp.h.
2229 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2230 to UTF-8, UCS-32, wchar_t or Latin-1.
2232 * Prototypes for yaz_iconv_-functions moved to separate header
2233 include/yaz/yaz-iconv.h.
2235 Make a few private functions 'static' in unix.c. This prevents
2236 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2238 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2239 are set when Init Response is received.
2241 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2242 but returns diagnostic set as well.
2244 New function yaz_strerror which is a portable wrapper for
2245 strerror/strerror_r/GetLastMessage.
2247 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2248 is returned for MARC. If type is "oai", then OAI MARC is returned.
2250 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2253 --- 1.9.2 2002/11/26
2255 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2257 Fix bad race conditions on SIGTERM and terminate gracefully in
2260 Move retrieval (data1) module to Zebra since nobody seems to be
2263 Add GRS-1 render for ZOOM using same format as yaz-client.
2265 --- 1.9.1 2002/10/05
2267 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2269 Fix broken ESpec handling in data1 module.
2271 SGML reader parses comments and makes them part of the data1 tree.
2273 Added several type casts so that YAZ compiles as C++ code.
2275 ZOOM didn't handle PDU encoding failures properly.
2277 Added more Bib-1 diagnostics (approved extensions).
2279 GNU configure: better check for iconv.
2281 More portable use of accept, getpeername. Check for socklen_t. Use
2282 int/size_t if socklen_t is not defined.
2286 PQF parser rejects bad queries - including those with extra
2287 characters in them. PQF parser used to silently ignore that.
2288 Cleaner API for PQF added, which allows you to get detailed
2289 error information for bad queries (see yaz/pquery.h).
2291 Fixed bug in ZOOM_record_get for type "database".
2293 Implemented mini iconv library supporting conversions between
2294 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2296 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2298 --- 1.8.9 2002/08/20
2300 Fixed ZOOM C record cache so that preferredRecordSyntax and
2301 elementSetName is used to check for already fetched records.
2303 --- 1.8.8 2002/08/02
2305 Added three members in bend_initrequest structure to facilitate
2306 character set negotiation.
2308 Fixed a bug in frontend server that could cause indefinite
2309 loops under rare conditions.
2311 Revised character set utilities (charneg.h) so that encoding
2312 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2314 For PQF, directive @term <type> sets term type for Scan/Search.
2315 Here <type> is general, string, numeric, null. The term type
2316 is inherited - just like @attr.
2318 New call odr_set_charset that sets character set conversion for
2319 international-strings on a ODR stream. Prototype is:
2320 int odr_set_charset(ODR o, const char *to, const char *from);
2321 The InternationalString is still represented as C string in YAZ
2322 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2323 won't). On the protocol level, you can use any encoding.
2325 Support for UNIX sockets in ZOOM.
2327 Solaris recv sometimes returns errno == ENOENT. It is treated as
2328 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2330 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2331 both client and server. Code by Morten Bogeskov.
2333 --- 1.8.7 2002/05/22
2335 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2336 that they can be used directly from Visual Basic. You must recompile
2337 your windows APP if you're using ZOOM.
2339 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2340 Commands "lang" and "charset" sets language and character set respectively.
2341 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2342 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2344 Attributes from multiple CCL fields may be OR'ed rather than merged
2345 using directive "@field or". Fields are still merged by default -
2346 equivalent to "@field merge".
2348 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2351 Fixed bug in zget for parameter ExtendedServicesResponse.
2355 --- 1.8.6 2002/03/25
2357 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2359 Client displays USR.1:SearchResult-1 (hits per term).
2361 Additional Search Info for search in Generic Frontend Server.
2363 Fixed CCL parsing of "field=s".
2365 WIN32 installer - using the excellent NSIS software from nullsoft.
2367 Fixed CCL parsing of "field = - <number>".
2369 Added function yaz_marc_decode that decodes MARC for line mode
2370 display or XML (similar to that used by JZKit).
2372 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2373 Z39.50. But ISO/ILL was, however.
2375 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2376 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2378 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2379 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2381 --- 1.8.5 2002/02/03
2383 New YAZ client features: Command completion and new commands:
2384 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2385 Code provided by Jacob Poulsen.
2387 New call oid_trav, that visits all registered OIDs via callback.
2389 Function ZOOM_record_get now returns const char pointer rather than
2390 void pointer. It saves a lot of type casts.
2392 For YAZ client, command "auth" now allows you to set authentication
2393 in IdPass style. It is enabled when three tokens are given - order
2394 is user, group and password.
2396 Fix memory leaks in MARC record handling for ZOOM.
2398 New option for YAZ client, -k <kilobytes> that sets
2399 maximum record size. Similar to -k option for generic frontend
2400 server and yaz-ztest.
2402 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2404 Prefix query parser reports "fail" when bad attribute set is given.
2406 Fix in MARC decoder. Proximity logging. Fix for attribute set
2407 in scan handler for server. Patches by Shigeru Ishida.
2409 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2412 Configure option --with-openssl=<dir> now works when a directory is
2413 specified. Patch provided by Morten Bogeskov.
2415 New option for YAZ client, -u <auth>, that sets authentication.
2417 ZOOM fix: error information was sometimes "missing", since error
2418 was cleared/reset too when it shouldn't.
2420 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2422 --- 1.8.4 2002/01/04
2424 Scan for ZOOM API. New object ZOOM_scanset. New functions
2425 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2426 ZOOM_scanset_destroy.
2428 New ZOOM function, ZOOM_connection_last_event, that returns type
2429 of last event (such as "receive data", "send data", "apdu received",
2432 New ZOOM option, schema, that specifies schema for retrieval.
2434 New CCL feature. Qualifiers can be aliases for one or more
2435 other qualifiers (if more than one is given, OR is used).
2437 ZOOM uses named result sets if target supports it.
2439 Two new YAZ client commands: . (dot, which sources a script of YAZ
2440 client commands), and ! (to execute shell command.). Implemented
2443 Working on Debian packages.
2445 --- 1.8.3 2001/11/19
2447 YAZ client enables named result sets only if target supports it.
2449 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2451 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2452 with key="host" to get same result.
2454 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2455 Function Z3950_resultset_record(s) returns references to records
2456 "owned" by resultset. To become owner use Z3950_record_clone.
2458 Function z_ext_record handles Extended Services. Thanks to
2461 --- 1.8.2 2001/11/12
2463 CCL Parser fix: ignore token comma when dealing with and-lists.
2465 Documentation updates for COMSTACK.
2467 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2468 Changed prototype Z3950_records. For some functions, int parameters
2469 were changed to size_t.
2471 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2474 New MARC decode/display function, marc_display_exl, which properly rejects
2475 non-ISO2709 records. YAZ client uses it.
2477 --- 1.8.1 2001/10/29
2479 Fix bug: local attribute set wasn't set correctly in PQF strings.
2483 * Old Z39.50 codecs no longer supported.
2485 Added ZOOM C binding. See http://zoom.z3950.org/
2487 Renamed states for COMSTACKs to avoid confusion with events.
2489 Implemented cs_look and proper cs_rcvconnect.
2491 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2493 Configure detects POSIX threads on OpenBSD.
2495 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2496 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2498 When error is returned from present handler, non-surrogate diagnostic
2499 is returned in present response (and fetch handler is no longer called).
2501 * Minor adjustments to pquery parser (PQF). Token characters may be
2502 escaped by using backslash (C-style).
2504 PQF parser allows string attribute values to be specified. For @attr,
2505 non-numeric characters after the equal-sign are treated as strings
2506 (e.g. @attr 9=title).
2508 CCL trunction character may be defined (@truncation in file)
2510 * function zget_ExtendedServicesRequest sets waitAction to
2511 waitIfPossible (was wait).
2513 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2516 CCL operator names may be set in field definition files (CCL_bibset).
2517 See ccl/bib1 for an example.
2519 Fixes in ASN.1 compiler for C++ compatibility.
2521 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2522 and "op_or" to avoid conflict with C++.
2524 Fixed problem with GNU readline detection on Redhat 7.0.
2526 Added step-size for Scan backend handler.
2528 Fixed bug that made the frontend server crash when no attribute
2529 set was specified for scan.
2531 Front-end server automatically switches to original working directory
2532 when installed as an NT service. Previously -w had to be specified to
2535 Added extended attributes for retrieval module (data1), so that data1
2536 records carry d1_readXML/SGML attributes. d1_read also supports
2537 null-data rules ( <tag/>)
2539 On UNIX when POSIX threads are available, a separate library libyazthread
2540 is created. Programmers should link with that library and the yaz library
2541 when using threads. The reason for the split was that some applications
2542 on Linux, such as Apache, doesn't work well when using shared objects that
2545 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2546 (or any frontend server) in SSL mode by specifying ssl: followed by
2547 address. Only tested on UNIX.
2549 Added feature for CCL module. Virtual structure s=al or s=ol generates
2550 and-list and or-list respectively instead of phrase search.
2554 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2555 log_mask_str. This was done to avoid name conflicts with other libraries
2556 (such as other PHP extensions).
2558 Added raw OID member for preferred record syntax (request_format_raw)
2559 and returned record syntax (output_format_raw) for backend fetch method.
2561 Config file yaz-config now accepts options so that it returns specific
2562 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2564 Shared library support for UNIX using GNU libtool.
2566 * Modified backend interface. Request/Response struct's replaced by
2567 one read/write C struct. For example bend_fetchrequest and
2568 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2569 Every handler - even search has to be registered in bend_init
2570 handler. This means that the YAZ library no longer refers to
2571 external functions and it makes it possible to make the whole
2572 thing a single DLL/SO.
2574 Added Segment handler for backend server.
2576 Added Zmbol/Zebra administrative functions to YAZ client.
2578 Threaded frontend server on UNIX (when POSIX Threads are available).
2579 Starting the server with option -T enables multi-threading.
2583 Added configure option --enable-comp/disable-comp to control use
2584 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2585 located in sub directory asn.
2587 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2588 in ${exec_prefix}/bin along with the other programs yaz-client and
2591 GNU automake used to maintain makefiles.
2593 Added several OID's.
2595 Changed retrieval module so that we can load records with no abstract
2596 syntax defined. Tagpaths in these records are fully composed of string
2599 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2603 On UNIX, the generated makefile now supports a proper 'make install'.
2604 The prefix can be set via GNU configure to set the install location
2605 (default is /usr/local).
2607 * YAZ programs client and ztest were renamed to yaz-client and
2608 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2609 locations, such as /usr/bin,/usr/local/bin,etc.
2611 * YAZ Header files were moved from include to include/yaz. YAZ Header
2612 files are referred to as include <yaz/log.h> rather than <log.h>.
2613 The YAZ include path (-I ..) is therefore the same as before. Programmers
2614 should update their #include statements or use -Ipath/include/yaz
2615 instead. The main motivation for doing this change is that YAZ header files
2616 can be installed in "standard" locations /usr/include,/usr/local/include
2617 without introducing conflicts, since ALL YAZ header files are stored
2618 in subdirectory yaz (under /usr/include for example).
2620 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2621 rather than project/workspace files. We switched because project files
2622 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2625 Changed name of logging function, logf, to yaz_log, to prevent name
2626 clash with some math-log functions. The YAZ header log.h defines logf
2627 to yaz_log (#define) so there should be no incompatibilities by this
2630 Added bend_start/bend_stop handlers for server. These handler are
2631 called on start/stop of server. For windows they are called whenever
2632 a service is started/stopped.
2634 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2635 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2636 in util/yc.tcl. The auto-generated C code structures are, in a few
2637 cases, incompatible with the old decoders. There are differences in the
2638 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2639 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2640 The preprocessor variable ASN_COMPILED is defined when the compiled
2641 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2642 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2643 wish to use the old encoders/decoders you can specify --disable-yc
2646 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2647 version so that it supports both new - and old version of DB Update
2649 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2650 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2651 change. The name parameter can be set to 0 in which no name is specified
2652 for the construction. The macros odr_implicit and odr_explicit sets name
2653 parameter to zero for the construction involved. New macros
2654 odr_implicit_tag and odr_explicit_tag are similar to the others,
2655 except that a name parameter is added. For programmers' that don't use
2656 ODR they probably only need to change the call to z_APDU and z_External.
2658 Added access control facility by interfacing the TCP wrapper library.
2659 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2660 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2661 name of the daemon and enables the access control as specified in
2662 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2664 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2665 den Dool <H.M.vdnDool@kub.nl>.
2667 Added reference ID parameter to most functions in server API - refer
2668 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2670 Changed name of ccl library to libccl.a (was ccl.a).
2672 Fixed bug in decoder for Explain (Category TargetInfo).
2674 Added support for GNU readline in client. Thanks to Jacob Poulsen
2675 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2677 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2678 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2679 IMPLEMENTATION! This change was made to the development version before
2680 the ZIG decided to retract the amendment. If any users MUST be
2681 compatible with the original Update definition, PLEASE CONTACT US, and
2682 we will include a separate definition corresponding to the old Update
2683 ES. Note that because of the change to the ASN.1 of the
2684 TaskPackageRecordStructure we cannot define a single structure that
2685 will support both versions.
2687 * Added const modifier to buffer parameter for some ODR/BER encoding
2688 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2689 completeWAIS, odr_dumpBER.
2691 Fixed bug in client.c which caused a crash when a scanResponse didn't
2692 contain positionOfTerm.
2694 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2695 * will cause an error in a client if a non-YAZ target sends both a
2696 * list of Scan entries and non-surrogate diagnostics.
2698 Retrieval module enhancements. Tag sets may be typed in the reference
2699 to it. From the .abs-file the "tagset" directive takes a third optional
2700 integer type for the tag set referenced. From a .tag-file the "include"
2701 directive takes a third optional type as well. The old "type" directive
2702 in the tag set itself is still recognized but acts as the default type
2705 Backend interface change. Individual Scan terms returned from bend_scan
2706 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2707 in include/backend.h.
2709 Retrieval module enhancements. Multiple tag sets and attribute sets may
2710 be specified in abstract syntax specs. Revised the error/warning for
2711 logging messages reported by the retrieval module when reading the
2714 Object Identifier system (oid_..) changed. The API is backwards
2715 compatible but the oid-routines now allocates new OID's when needed.
2716 Raw OID's may be specified in oid_getvalbyname.
2718 YAZ now uses GNU configure to generate Makefile(s).
2720 * Minor changes in some of the member names of DeleteResultSetRequest and
2721 DeleteResultSetResponse. See include/proto.h.
2723 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2724 and added member 'languages' in TargetInfo (which was missing).
2726 Changed the way attribute sets are handled in the retrieval
2727 module. These are now cached, just like the abstract syntaxes
2730 Changed YAZ so that it links with compiled ASN.1.
2732 Added Explain-schema definitions and mapping routines. The following
2733 Explain categories have been implemented: AttributeDetails,
2734 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2736 Fixed minor bug in Windows version of Server Library.
2738 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2740 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2742 Added EXTERNAL: UNIverse Resource Report (non-standard).
2744 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2745 ENUMERATED and SET OF.
2747 * Added 'const' to some of the char pointer arguments for the
2748 functions, data1_read_node, data1_getelementbytagname,
2749 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2752 Fixed bug in data1_insert_taggeddata - the last_child member of
2753 parent wasn't initialised.
2755 * Changed data1_read_record and data1_read_node so that the supplied
2756 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2757 doesn't refer to any parts of the "SGML"-buffer.
2759 Fixed bug in server library (Windows version of statserv_remove).
2761 * Changed code so that it compiles as C++. The type definition
2762 of Odr_fun which is a member of Odr_arm was changed. The result is,
2763 that an explicit typecast is needed for the fun pointer when
2764 using Odr_arm - as in:
2765 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2767 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2769 Implemented the new structured date and time definition as approved
2770 by the ZIG. Added schemaId element to the specificTag in Espec-1
2771 (also approved at the last ZIG). Thanks to RVDM.
2773 Added some Object identifiers (RVDM).
2775 Changed the Update Extended Service (RVDM).
2777 Added command "refid" to client which specifies referenceId for
2778 the following requests.
2780 Implemented extended service handling for server. See ztest.c
2781 for an example as well as backend.h. New handlers are registerd
2782 in the Init handler.
2784 * Changed interface for sort in server.
2786 Added new members to statserv_options_block. It allows a server
2787 to read options from another source than just the command line. Thanks
2788 to Charles Woodfield.
2790 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2791 renamed to zboolean. Some C++ compilers complained about the name.
2793 Minor changes to gils.abs. Added index 's' (sort) on title
2794 and date/time-last-modified.
2796 --- 1.4pl2 1998/1/30
2798 Fixed bug in server library regarding inetd mode (-i). This bug
2799 was introduced by release 1.4.
2801 --- 1.4pl1 1998/1/29
2803 Added sort facility in client and backend server interface.
2805 Fixed problem with dependencies in Makefile(s).
2807 Fixed bugs for encoders/decoders of extended services and
2810 Implemented sub-tree feature for schemas. Sub-trees are
2811 referenced in *.abs-files. See explain.abs for an example
2812 of the use of this feature.
2814 Modified bib1.att; local attributes for ANY didn't include
2815 ANY itself (only affects use of the retrieval module).
2817 Fixed bug in plain SGML reader in function data1_read_node:
2818 tags with prefix "var" was incorrectly interpreted as variants.
2820 Added feature "sub-schemas" to enable references to - and definitions
2821 of - group of elements.
2823 * Removed member parent from type data1_element (in data1.h).
2825 Implemented function odr_nullval() that returns the value of
2828 * Removed member num_children from data1_node (in data1.h).
2830 Made NT service interface part of the server library. The
2831 function statserv_main uses the NT service when required and
2832 calls the statserv_start / statserv_close routines.
2834 Routine zget_SearchRequest and zget_PresentRequest fills
2835 resultSetName/Id member with "default" instead of "Default".
2837 Fixed memory leak in server. Request queue member wasn't freed.
2839 Fixed nmem_exit so that memory is freed.
2843 Revised the CCL parser utility to be thread safe.
2845 Added function, oid_ent_to_oid, to replace the function
2846 oid_getoidbyent, which is not thread safe.
2848 * Added nmem_init and nmem_exit to initialize and release
2849 NMEM resources. Function nmem_init should be called once in the
2850 initial thread before NMEM/ODR is used. statserv.c and client.c
2851 have been changed accordingly. The change was necessary to make
2852 NMEM thread safe. The NMEM memory pool is shared amongst threads
2853 in a process. Unix-based applications will still work fine without
2856 Added NT Services interface for the the Z39.50 (statserv) Server.
2857 Refer to the ztest.c source on the usage.
2859 Windows 95/NT port using MSVC5.0. Project files are included in the
2862 * Defined new 'global' handle for the retrieval (data1) system. The
2863 new handled, data1_handle, describes the state of the data1 system.
2864 This handle is passed as first argument to virtually all
2865 data1 related routines. The functions data1_create and data1_destroy
2866 creates and destroys a data1 handle respectively.
2868 Added ODR encode stream member to all backend request structures
2869 init, search, scan etc. This stream should be used to allocate all
2870 memory used for the response when thread safe operation is needed.
2872 Changed the comstack utility, cs_addstr, to be thread safe. The
2873 returned hostname string returned by the function is now part the
2876 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2877 function. The cs_straddr takes a COMSTACK handle as argument, so this
2878 function must be used after cs_create and before bind/connect.
2879 This function is thread safe.
2881 Moved test server to 'ztest' directory - generic server code still
2882 in 'server' directory.
2884 Made prefix query (pquery.c) utility thread safe.
2886 Added new function modifier YAZ_EXPORT to 'export' public DLL
2887 functions when using windows (see include/yconfig.h).
2889 Added definitions to the OID database (util/oid.c) (RVDM).
2891 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2893 Added call to ccl_rpn_delete in client program.
2895 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2896 release of RPN structure.
2898 Added support for C++, headers uses extern "C" for public definitions.
2899 With input from RVDM.
2901 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2902 Thanks to Ronald van der Meer (RVDM).
2904 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2906 Added support for private extensions to the OID database
2907 (oid_setprivateoids()). Thanks to RVDM.
2909 Added optional, physical ANY (key replication)
2911 Fixed null-reference problem in GRS-1 output filter.
2913 Proximity operator added to Prefix Query Format (PQF).
2915 In test client command "base" accepts multiple databases.
2917 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2921 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2923 Smallish bug-fixes in the new encoders/decoders (explain).
2925 Bug fixed in DeleteRequest.
2927 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2929 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2931 Added SOIF syntax (using private OID for now) to retrieval module and client.
2933 Added Update extended service.
2935 Added SearchResult-1 additional info structure.
2937 Added optional CCL (ISO8777) interpreter as separate module. Available
2940 --- 1.2 1996/6/10 (1st anniversary release)
2942 Added Summary record syntax. Lightly tested.
2944 Added OPAC record syntax. Untested.
2946 Added ResourceReport service encoders/decoders. Untested.
2948 Fixed bug in z_Unit - wrong tagging on unitSystem.
2950 Fixed bug in the DiagRecs decoder.
2952 Added options for max PDU size and session timeout to frontend-server.
2954 Added documentation of query-language parsers and other supporting utilities.
2956 [frontend-server] Added Attribute set to the bend_scanrequest API.
2958 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2959 surrogate diagnostics were generated.
2961 [retrieval] Allow multiple local values for attribute.
2963 [retrieval] Allow multiple attributes per element in .abs files. index type.
2965 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2967 --- 1.1pl2 1996/4/10
2969 Minor changes, mostly specific to Zebra's requirements (retrieval)
2973 Repaired bug in frontend server when running multiple listening
2974 endpoints in dynamic mode.
2976 z_External() now won't break if a known, ASN.1 value comes encapsulated
2977 in an octet-string. The value will pass through unmodified in an Odr_oct.
2979 Added a bit of code to the demo client to decode & display
2980 ASN.1-structured records represented in the octet-aligned branch of
2981 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2983 Added z_ext_getentbyref() to the ASN module. Doc updated.
2985 * Completed the SCAN definition in the ASN module. This may break SCAN
2986 code based on older YAZ-versions at compile-time. The fix is easy -
2989 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2990 under the SCAN definition. Remember to initialize this, server-people.
2992 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2993 that this does not extend to ODR and ASN.
2995 Comstack allows insertion of established socket (primarily for
2996 inetd-operation of servers). Doc updated.
2998 Front-end server can now start from the inetd in TCP mode. Doc
3001 --- 1.0pl4 1996/1/24
3005 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3006 the rank and record number.
3008 Adjustments to the frontend server.
3010 Fixed diagnostic BER dumper. It ignored the file argument.
3014 Various changes to retrieval module.
3016 Changed the union discriminators of the protocol files from enums to
3017 ints paired with #defines.
3019 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3022 *Changed operator in the RPN structure to 'roperator', again to avoid a
3025 Fixed problems in Explain decoders/encoders.
3027 --- 1.0pl2 1995/12/6
3029 Memory bug in log module fixed.
3031 --- 1.0pl1 1995/12/5
3033 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3035 Bug in Explain DatabaseInfo module fixed.
3037 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3041 The shift to v1.0 signals that we now consider the *core* functionality
3042 of YAZ reasonably stable (the core being more or less equivalent to
3043 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3044 tested (Explain not at all - though that will happen soonish).
3046 Minor changes to code to support Windows port.
3048 Various minor changes after we're getting to use GRS-1 & co. more.
3050 Added Espec-1 format.
3052 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3053 of the protocol and it cannot be selected when encoding (maps into 'string'
3054 when decoding). Needed to talk to some servers.
3056 Demo client can request simple element set names.
3058 Added Diagnostic Format encoders/decoders.
3060 Added simple Close handling to frontend server (no hooks for resource
3061 reporting yet), and demonstration client.
3063 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3065 --- 1.0b3 1995/08/24
3067 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3068 handled incorrectly when records were requested in the searchResponse. This
3069 will only affect you if you use the frontend-server.
3071 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3072 Test-client will ask for and print GRS1. Ztest will return dummy records
3075 Added Explain encoders/decoders to the service-level API. Untested.
3077 Added Extended Services: Item Order encoders and decoders to the Service-
3078 level API. Untested. We could use a recent copy of the pertinent bits
3079 of the ILL protocol to add those bits.
3081 Added diagnostic format 1 encoders/decoders to the service-level API.
3084 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3085 odr_cons.c, which causes a more correct output.
3087 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3088 was always set to 0 when no records were requested in the searchRequest.
3090 * Added better external-handling. This shouldn't harm old code that
3091 *encodes* externals. It can break code that looks for a
3092 'single-ASN1-type' representation, since those types that are known
3093 are now decoded immediately. Look at the SUTRS sample code in
3094 seshigh.c and client.c. Documentation updated.
3096 Handling of structured records in bend_fetchresponse. Length -1 marks
3097 structured record, type is deduced from format field.
3099 --- 1.0b2 1995/06/27
3100 Fairly quick maintenance release to add SUTRS support.
3102 Fixed handling of SUTRS records in the demonstration client.
3104 * Added format field to the bend_fetchrequest and bend_fetchresponce
3105 structures of the backend API (frontend server). When the record is
3106 returned, the value of the format field is mapped to an OID. The
3107 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3108 of the record. The special value VAL_NONE in the bend_request means
3109 that no specific format was requested by the client. Documentation
3110 updated accordingly. Test server (ztest) will return a fixed dummy
3111 SUTRS record if your client requests SUTRS.
3113 Documentation updated accordingly.
3115 You can now set external libraries and RANLIB support in the top-level
3119 First public release.
