1 CCL: allow parantheses for proximity operands. For example CCL query
2 (a) % (b) is now allowed.
4 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
5 marked dead, rather then being destroyed. If not, the session memory is
6 being free'd before the search/scan handler is finished. Also destroy
7 'request' memory in request_release rather than in various places,
8 which resulted in leaks from time to time.
12 cql_sortby_to_sortkeys: honor sort prefix.
14 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
15 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
16 The rpn2cql family of functions now always returns quoted CQL terms.
18 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
22 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
23 sequence is treated as one. For example, &&a=b&&&c& is identical to
28 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
29 APDUs for a connection to a WRBUF.
33 Fix cql_sortby_to_sortkeys. Completely broken before.
35 Make CCL's @truncation work again.
39 New ZOOM connection setting: tproxy. It's like proxy, but does not
40 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
41 to set resolved address + port for a connection outside ZOOM itself.
43 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
47 Fix uninitialized variable in Solr spell support (could cause SEGV
48 for SRU response decoding).
50 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
51 back-end's addinfo through into the ZOOM response addinfo.
53 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
54 they are separated by a colon and a space rather than simply
59 Add support for Solr spell-checking/suggestions through ZOOM.
60 If a Solr target has been configured correctly for spelling-checking
61 and suggestions, these will now be returned on the ResultSet option
62 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
66 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
67 with a flag whether to substitute escape sequences or not.
71 Fix nmem_strsplit_escape to substitute escape char properly.
73 New option for zoomsh -e , which makes it abort on first error and
74 return process exit code to indicate success/failure.
76 YAZ options utility supports special option -- which makes all it treat
77 all following arguments as non-options.
81 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
82 searched if absolute filename is given.
84 Fix conv_xslt() error-reporting when stylesheet is not found.
85 (The value of fullpath is meaningless in this situation.)
89 Fix problem in CQL sort node creation: un-initialized memory.
91 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
92 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
93 CQL sortby depending on whether Type-1 or CQL is actually sent to the
96 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
97 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
99 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
100 will make it possible to use both single-character mask (#) and wildcard (?)
101 in CCL . Throw diagnostic for left truncation because that is not supported
104 --- 4.2.13 2011/09/01
106 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
107 cases using escapes (\-sequences) and masking.
109 PQF parse fix: A trailing backslash followed by end-of-string (\0)
110 would result in a read one byte beyond string.
112 rpn2ccl may use Z39.50 masking for terms (t=z).
114 ICU check fix. Don't include library -lCrun on Solaris, unless present.
116 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
117 not --cppflags (which seeems like an error in icu-config).
119 --- 4.2.12 2011/08/27 RPM package only
121 cql2ccl: fix conversion of terms: operator characters were not
124 --- 4.2.11 2011/08/25 RPM package only
126 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
127 CCL parser will map both # and ? to their regular expression
128 quivalents (. and .*).
130 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
131 of reserved CQL characters.
133 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
134 is, so that they are passed through.
136 --- 4.2.10 2011/08/24
138 ZOOM SRU mode: more aggressive re-connect.
140 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
141 made available as a utility function, declared in <yaz/logrpn.h>
143 rpn2cql_structure() supports proximity nodes (except that the Type-1
144 proximity node's "exclusion" binary is ignored, as there is no way to
145 express that in CQL). Fixes bug #4564.
149 Fix SEGV that could occur if set command of zoomsh was given without
150 value (2nd argument).
152 Fix SEGV that could occur if unsupported transport was given for
153 COMSTACK - say https (when SSL was unavailable).
155 Build yaz-url on Windows too.
159 New utility to get web content. Header is url.h. A command line tool
160 yaz-url is part of the distribution and packages.
162 Fixes for SSL COMSTACK (when gnutls is in use).
164 New functions yaz_base64{encode,decode}. Header is base64.h.
168 ZOOM C includes HTTP response buffer as additional info if it fails
169 to decode the SRU response.
171 Make wrbuf_json_puts available.
175 zoom: throw diagnostic for invalid value for option "sru". Before a
176 bad SRU request was sent.
178 Adding new utility wrbuf_vp_puts.
180 Add cclxmlconfig.obj to win/makefile. It was missing completely.
184 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
185 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
186 redirect was used at the same time.
188 MARC line mode decoding: be less picky about length given - first
189 5 digits of header that is.
191 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
193 Changes to decoding of SRU records: a record with recordPacking=xml is
194 modified with a new root element <yaz_record> if the recordData contains
195 multiple children elements. This is to make the record XML parseable
198 RPN to SOLR conversion: encode special characters.
200 Generic Frontend Server: fix uinitialized member, stepSize.
204 Fix a bug in SRU decoding of records.. The database records stored
205 had un-initialized memory, but it would only be seen with yaz_record_render
206 and type_spec="ext" .
208 Fix a bug in ccl_qual_dup introduced in 4.2.3.
212 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
216 Add new utilities to convert from CQL to CCL . These utilities have
217 prefix cql_to_ccl defined in cql.h.
219 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
220 lead to memory heap corruptions when ICU utilities were in use.
224 Make compilation work without Libxml2.
226 yaz-client: remove redundant blanks in display of searchResult-1 term
231 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
232 resulting CQL node (tree) in a new node CQL_NODE_SORT.
234 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
235 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
236 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
237 Note that the CQL sortby spec is only converted when the GFS is already
238 converting from CQL to RPN (cql2rpn element).
240 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
241 specify whether to collapse delimitors or not. The existing nmem_strsplit
242 do collapse (collapse parameter = 1).
244 Windows installer: For NSIS, set InstallDir depending on x86/x64.
246 Rename internal func yaz_use_attribute_create. While non-static, this
247 function is not declared in a public header.
251 Add -lCrun when linking with ICU on Solaris.
253 More quicks character set conversions for OPAC records.
257 fix problem with record_render: records were converted (character set
258 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
262 SRU: add methods for handling DADS SRU-proxy facets.
264 Separate OPAC record character set for ZOOM_record. yaz_record_render
265 allows a character set given as charset=from/opacfrom,to where 'from' is
266 the character set of a bibliographic record, 'opacfrom' is character set
267 of OPAC record and 'to' is the target character set.
271 yaz-client: show may XML format records. Command show followed by 'format'
272 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
275 src/stemmer.c: Avoid using unnamed union. It is not supported by some
278 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
281 Update yaz.spec to operate on both SLES11 / Centos 5.5.
283 RPM: Release includes 'indexdata' name. Use indexdata in release name so
284 this package can be distinguished from other vendors.
286 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
287 as determined by configure
289 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
291 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
292 returns no error and no record, the present request is considered
293 partial (only a subset of the records could be returned by backend), and
294 so it is appropriate to set Present Status to partial-4.
298 Move yaz-config man pages to section 1.
300 More documentation about SOLR.
302 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
303 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
304 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
305 peers on some Linux systems. However, in general that does not work
306 so YAZ can not rely on that to work. Debian changed behavior in this
307 respect from Debian lenny to Debian squeeze (still testing as of Oct
309 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
311 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
315 Fix yaz-config output: echo_source not set correctly by configure.
319 SOLR WebService support for yaz-client and ZOOM.
321 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
323 --- 4.0.12 2010/08/17
325 Z39.50 facet support. Facet specifications are passed for search in
326 other-information with ASN.1 as defined in facet.asn and OID
327 .10.1000.81.5 . Facets are expressed as an Attribute list as known
328 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
329 3 is limit (number of entries to get in response). yaz-ztest returns
330 dummy facets if a client asks for them.
332 --- 4.0.11 2010/07/09
334 CCL fixes: bug 2895 and bug 3539.
336 GR1-display: add comma in display - was removed by mistake in
339 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
341 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
343 --- 4.0.10 2010/06/18
345 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
346 result set from a connection. The result set will be on its own
347 thereafter; no operations on it will perform retrievals from a target.
348 Only cached copies are returned.
350 ZOOM C:fix case for HTTP servers responding with Connection:close.
351 Ensure that if there is a current task it is resumed (like fetching
352 more records in a result set) . Bug #3484.
354 PQF parser: use odr_atoi for Odr_int (not atoi)
356 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
357 values that contain any non-digits are treated as string attributes
358 (previously decoding only checked for leading character ([0-9]). PQF
359 encoding: attribute string values are not surrounded by double-quotes.
363 New utility for managing threads - thread_create.h.
365 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
366 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
367 but YAZ' implementation do.
369 Fixes for yaz_cond-functions on Windows 7.
371 DLL export more symbols.
373 zoomsh: show record do NOT render opac.
375 Remove *.la files from Debian and RPM packages.
379 Debian package libyaz-dev depends on libgnutls-dev again (was
380 removed in YAZ 4.0.6, but due to Libtool it is still needed
381 even though yaz-config do not list libgnutls libs).
383 ZOOM: Use only one WRBUF for returning string results for
384 ZOOM_resultset. Reduces memory usage for ZOOM in general.
386 ZOOM: ZOOM_connection do not use a shared pointer to
387 ZOOM_resultset after ZOOM_resultset is destructed by
388 user. Reverts to YAZ 4.0.4 behavior.
392 record-conv: fix problem with at least one XSL conversion -
393 due to probably incorrect usage of XML XSL documents.
397 Fix yaz-config for static mode and the use of SSL (gnutls).
401 Forward decl timeval struct in mutex.h and gettimeofday.h.
403 yaz-config: fix 'static' mode linking.
407 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
408 are wrappers for pthreads or Windows. For Windows these are put in
409 a separate DLL: yaz_cond4.
411 libyaz.la (whole source) is compiled with thread. If thread support
412 is enabled enabled, all source of YAZ is compiled with treading support.
413 This allows core utilities such as yaz_log to use thread facilities.
414 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
415 thread utilities. This commit moves mutex utilities (mutex.c) from
416 libyaz_server.la to libyaz.la.
418 yaz-json-parse displays leading text until error.
422 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
423 patch from Giannis Kosmas.
425 SRU: no longer URL encode SRU database. The URL for an SRU server is
426 a URL and such is alreeady encoded - at least when given with leading
427 http:// or https://. This reverts behavior to YAZ 3.0.50.
429 Support for new MARC XML notation TurboMARC which like MARCXML is a
430 complete representation of MARC/ISO2709.. This one, however, is more
431 compact and allows for faster processing with XSLT. TurboMARC can be
432 used in the marcdisp.h API, from the yaz-marcdump utility and from
435 yaz-ztest can be configured - via the database - to perform certain
436 delays when it performs operations search, present and single record
437 fetch. This allows testers to make yaz-ztest act as a real or even slow
438 Z39.50 server. Refer to the yaz-ztest man pages for details.
442 wrbuf_destroy allows NULL WRBUF passed to it.
444 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
446 Add ZOOM_connection_close.
448 No fixed size buffers for ZOOM shell - bug #3257.
450 tstodr: make it work on s390 platform.
452 New icu iterator-functions. The new icu_iter-functions makes it possible
453 to use ICU chains from many threads.
455 yaz-client: better syntax check for show command.
459 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
462 New simple local-file XML include facility which allows file glob-patterns.
463 Refer to yaz/xml_include.h.
465 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
468 ZOOM_record_get supports new parameter "format" which makes it format XML
471 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
472 JSONText in ECMA-262) is JSONValue, not JSONObject.
476 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
477 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
479 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
480 POSIX/Unix builds .so with major version 4.
482 Remove old LOG_-defines from log.h. They have been obsolete and
483 undefined by default for the last 5 years.
485 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
487 GFS: Remove socket (int *fd) from search_rr handler. The socket
488 descriptor ptr is a facility that allowed a search handler to supply
489 a socket which would serve as a callback - when search was complete.
490 This facility has now been in use for years.
492 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
493 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
494 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
495 returns 'const char *' rather than 'char *. The returned string is
496 read-only and should not be modified by applications. COMSTACK cs_close is
497 now a void function - it no longer returns int. No applications check for
498 the value and the implementations has always returned 0.
500 ZOOM: use size_t for scan hit counts and str size. Functions
501 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
502 occ (hit count) and len (string length) are now of type size_t pointer
503 rather than int pointer. This is to be able to represent large hit counts
504 and to also just to use the proper type for string length (strlen result).
506 New JSON parser. Refer to include/yaz/json.h .
508 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
509 Used to be int in some cases. Many wrbuf_-functions used to return an int
510 indicating some length.. These return values were never used. And so they
513 ODR: odr_malloc, odr_total now takes size_t for size.
515 clone_z_type: fix leak; occurred for encoding failures.
517 --- 3.0.52 2009/12/03
519 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
520 bug was introduced in 3.0.51.
522 --- 3.0.51 2009/12/02
524 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
526 tcpip comstack: fix leak for getaddrinfo.
528 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
529 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
530 Decoding of SRU "path" database is performed by private function
531 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
532 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
534 yaz-client: honor base command for SRU. Change when database setting
535 is applied for SRU and ensure it is kept when a connection is reset.
536 Change also the way errors are displayed or SRU (decoding of packages).
538 --- 3.0.50 2009/11/02
540 Add support for extra request / response data for SRU codecs and GFS.
541 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
542 for extra data response buffer and length. For the GFS, both request
543 and response data (XML) is carried in extra_args and extra_response_data
544 for the search handler. Patch by Ko van der Sloot.
546 ZOOM: For queries that cannot be converted to the specified rpnCharset,
547 ZOOM now returns a diagnostic on the client-side ('invalid query' /
548 10010). This fixes bug #2113.
550 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
551 cmdfile included a 'quit' command that would result in a memory violation.
553 --- 3.0.49 2009/10/01
555 Make a number of functions defined in xmlquery.c static. These have
556 never been declared in a public header file (yaz/xmlquery.h) and was
557 made public by mistake.
559 Improve speed of character conversions (iconv utilities). This makes
560 conversions from MARC-8 faster.
562 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
563 unless type desired is "raw". This will prevent type "xml" from
564 returning ISO2709 .. Which obviously can not be XML parsed.
566 Fix memory leak in ZOOM that would occur if option apdulog was used
567 on a re-used connection.
569 Frontend server logs HTTP requests.
571 Frontend server now sends Z39.50 close when it times out (sesssion has
572 been idle for too long). Versions 2.0.30 and earlier also sent close.
573 But due to a mistake this was disabled in all versions after that, i.e.
574 the server would just close the socket immediately.
576 yaz-client emits a better message when receiving an unrecognised
577 userInformationField.
579 Skip zero-length subfields when decoding ISO2709. This rare case happens
580 if a record has two FS characters in a sequence. Without this patch
581 there would be a reference beyond char array in using_code_len fragments
584 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
586 --- 3.0.48 2009/08/28
588 The show command offered by the zoomsh command now takes a 3d optional
589 parameter type which is what is passed to ZOOM_record. If the type
590 argument is omitted, "render" is used.
592 RPN to CQL conv may use USE string attributes (bug #2978).
594 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
596 --- 3.0.47 2009/07/08
598 Function yaz_xml2query allows a diagnostic element in the PQF XML
599 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
600 code and additional info respectively.
602 The BER BOOLEAN is now the integral type Odr_bool which still happens
603 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
604 typedef'd to Odr_int. This is still an integral 'int', but it may be
605 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
606 ASN-1 compiler as well as programs has been updated to use the new types.
608 --- 3.0.46 2009/06/08
610 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
611 only the bibliographic record was rendered. For type=opac, an OPAC
612 record is only returned if it is present.
614 iconv: small fix for encoding of advancegreek.
616 yaz-client: avoid double display of SRU/SRW records (bug #2798).
618 yaz-client: option auto_reconnect=on really reconnects.
620 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
622 server: avoid null ptr ref for for yaz_poll errors.
624 build: fix RPM build for RHEL 5.3.
626 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
628 --- 3.0.45 2009/03/31
630 Fixed bug #2709: TCP connect returns Invalid argument.
632 Fixed compilation for mingw.
634 Honor charset for raw records (ZOOM_record_get).
636 Fixed use of errno for threaded mode that was seen on Solaris 10.
638 Fixed argument passing with blanks in value for Windows Service.
640 Disable YAZ' own log rotate by default (no 1 GB limit).
641 The variable l_max_size which specifies the log file limit is set to 0
642 (DISABLED): This is due to the fact that YAZ is most often deployed using
643 logrotate. Also YAZ can not perform log rotate because of unsufficient
644 permissions (setuid).
646 --- 3.0.44 2009/02/17
648 List supported encodings in man page for yaz-iconv.
650 Fixed missing SSL libs for --libs output
652 Re-established OID record syntax application-xml. Nobody should use it
653 but we don't want to change soname because of this symbol being absent.
655 --- 3.0.42 2009/02/02
657 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
659 Added member named_result_sets for init handler struct for the GFS. This
660 allows a server to disable named result sets.
662 Removed OID record syntax application-xml.
664 Added support for rule-based transliterator for ICU wrapper of YAZ.
666 Fixed bug #1902: yaz-icu XML output.
668 Make YAZ checks Emacs friendly.
670 BITSTRING value shows value. Bug #2346.
672 ISO2709 decoding: skip control characters from indicator data.
674 Omit sort key by default in yaz-icu's output.
676 Allow combined single char options (again) for YAZ' options function.
678 Utility yaz-marcdump got option to display YAZ version (-V).
680 Allow YAZ to use ICU 3.4.
682 Added new ICU test case which illustrates removal of diacritics.
684 --- 3.0.41 2008/12/29
686 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
688 --- 3.0.40 2008/12/29
690 For configure, using option --without-xml2 also disables Libxslt/Libexslt
693 Fixed bug #2352: yaz-marcdump crashes for certain record.
695 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
697 Added support for Danmarc2 to UTF-8 conversion.
699 Added support for ISO5426 to UTF-8 conversion.
701 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
702 implementation version.
704 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
706 --- 3.0.38 2008/11/10
708 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
709 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
711 ZOOM C now interprets databaseName option for ZOOM connection as path
714 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
716 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
718 Dummy Libxml2 types no longer defined in headers of YAZ'.
720 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
723 --- 3.0.36 2008/09/26
725 Various ODR chapter fixes.
727 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
729 Added missing source for Windows compilation, mutex.c.
731 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
733 For SRU connections in ZOOM all records up to "count" are now fetched.
735 Fixed crash in generic frontend server (and yaz-ztest) which occurred
736 in Windows due to bad error handling for Libxml2.
738 Added facility for sending arbitrary records (ASN.1 any) using
739 ZOOM C's Extended service update. Patch by Sam Reynolds.
741 New options for ZOOM C's connection, logapdu which makes ZOOM log
744 --- 3.0.34 2008/06/18
746 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
748 --- 3.0.32 2008/06/12
750 Fixed memory violation that could occur when decoding UTF-8. This bug
751 was only present in 3.0.30 of YAZ.
753 --- 3.0.30 2008/06/06
755 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
756 GNU TLS is used by default (if found).
758 yaz-ztest returns OPAC records if a client asks for OPAC.
760 Improved speed of MARC-8 encoding.
762 Added support for lossy and loss-less MARC-8 encoding.
764 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
766 Added new Windows Service wrapper (sc).
768 yaz-client's itemorder command may now send a file.
770 Fixed yaz-marcdump to allow the use of NS prefix for record element.
772 Added new function yaz_log_xml_errors.
774 Allow (but warn) unknown XML attributes in MARCXML parsing.
776 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
778 The UTF-8 to MARC-8 conversion now uses a different set of characters
779 for Greek symbols. Bug #2120.
781 --- 3.0.26 2008/02/21
783 Added yaz_daemon (daemon.h).
785 Fixed bug #2068: pkg-config trouble
787 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
789 --- 3.0.24 2008/01/28
791 Document --with-xml2 option.
793 Added OPAC XML XSD (etc/opacxml.xsd).
795 Allow glob mask for name attribute in retrieval element for the
796 generic frontend server's retrieval facility.
798 Changed yaz_poll_poll to return yaz_poll_except for all returned events
799 except POLLIN/POLLOUT.
801 Fixed error handling in cs_listen. Bug #2037.
803 --- 3.0.22 2008/01/20
805 Fixed version in yaz/yaz-version.h.
807 Fixed bug #2027: Crash when closing connection.
809 Changed configure so that ICU support is only enabled if only ICU
810 and Libxml2 is available (because the ICU chain is XML based).
812 --- 3.0.20 2008/01/15
814 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
815 is built. Only this DLL depends on the ICU runtime.
817 yaz-ziffy is no longer part of YAZ. It is distributed separately by
818 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
820 Changed license of CCL module to 'Revised BSD'. After consultation with
821 remaining members of the original EUROPAGATE consortium, we are re-issuing
822 the CCL module without a separate license. The software was developed by
823 Index Data as part of a research project. The special license was included
824 to help feed usage information back to the project consortium to support
825 project evaluation. At this time, the project consortium has long-since
826 disbanded, and the majority of the original principals have retired. At the
827 same time, we have significantly modified the software during the following
828 years, to the point where very practically no original code remains. To
829 simplify re-use of the software, we have contacted those members of the
830 consortium who could be reached, and agreed to re-issue the module as a
831 proper part of the YAZ package.
833 Tcl scripts uses /usr/bin/tclsh as preferred shell.
835 CQL closer to being version 1.2 compliant. CQL also allows free-form
836 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
839 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
840 bug could make Extended services handling crash in the ZOOM layer. This
841 bug was only present in YAZ 3.0.18.
843 --- 3.0.18 2007/12/19
845 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
848 yaz-marcdump reads and writes collection wrapped records.
850 Handle OPAC for record conversion module.
852 Fixes for ICU wrapper.
854 Allow ICU libs to be controlled with --with-icu .
856 --- 3.0.16 2007/11/12
858 Added yaz_poll which is a wrapper for select/poll. When poll is available
859 and non-buggy, it is used, by yaz_poll . This allows more than 1024
860 sockets to be in use.
862 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
863 functionality through an XML based configuration (ICU chain). This system
864 is useful for search facilities such as Pazpar2 and Zebra that needs to
865 perform tokenization of indexed material. The ICU code in a separate
866 library libyaz3_icu.a.
868 Added HTTP tunnel facility for COMSTACK, bug #1752.
869 This is a facility that allows a Web proxy, such as squid, to tunnel
870 Z39.50 traffic. This facility is "transparent" to must applications
871 using YAZ. It's enabled by using pseudo transport connect: followed by
872 the proxy address, followed by command, then follwed by he regular
873 "virtual" addresss. For example,
874 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
876 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
878 --- 3.0.14 2007/09/21
880 Fixed bad memory reference in ZOOM_record - cuased by member not being
881 initialized. This was a problem only in YAZ 3.0.12.
883 Fixed bug in conversion from MARC to XML: Non-XML characters in control
884 fields were not removed.
886 Changed the way C code is generated from codetables.xml. Made a MARC-8
887 conversion trie for each characterSet section rather than codeTable.
888 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
889 of codetables.xml from Larry Dixson, LOC. Bug #1464.
891 --- 3.0.12 2007/09/12
893 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
894 from ZOOM_record_error).
896 ZOOM C function ZOOM_record_get returns record schema for type="schema".
898 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
900 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
902 Better SRW-to-Bib-1 diagnostic mapping.
904 ZOOM C and yaz-client announces SRU version 1.2 by default.
906 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
909 Fixed in yaz_sru_decode to allow other version than 1.1.
911 --- 3.0.10 2007/08/22
913 Added support for SRU scan for ZOOM.
915 Added support for the use of the older versions or Extended Service
916 Update in ZOOM. To faciliate this, an option "updateVersion" may be
917 set to the version , 1=first, 2=second, 3=third. The third version is
918 what ZOOM C has used so far. And that, obviously, is the default.
920 Added support for CCL queries in Z39.50 queries sent to the GFS (and
921 therefore in Zebra and in SimpleServer-based applications). The new
922 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
923 qualifier file used to transform incoming CCL queries into Type-1 RPN,
924 which is passed into the back-end search callback function.
926 Added support for HTTP Basic authentication in clients: the SRU/W
927 codec encodes the username/password elements of the PDU structure
928 appropriately, and these may be set using the "user" and "password"
929 options in ZOOM-C applications (the same options that are used for
930 Z39.50 authentication).
934 Fixed bug #1208: SSL appears to be broken in ZOOM.
936 Fixed bug #1206: Libxml2 include path weirdness.
938 Added oid_name_to_dotstring.
940 Allow elementSetName to be specified for ZOOM C record update.
942 Allow waitAction to be specified for ZOOM C based for Extended Services.
944 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
945 syntax OID. Bug introduced in YAZ 3 series.
947 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
951 Fixed bug #1157: yaz-client does not read .yazclientrc from current
952 directory. yaz-client now reads commands from file given by option -f
953 if specified; then tries to read .yazclientrc in current directory.
954 Failing that, it reads .yazclientrc from user's home directory.
956 Added support for correlationInfo Note and ID for Record Update via
959 Added yaz-client command querycharset which specifies character set for
960 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
961 (termListAndStartPoint).
963 Charset ISO5428:1984 is an alias for ISO5428-1984.
965 Implemented a way to perform scan in a result set using Z39.50. This
966 is achieved by attaching the result set name in the characterInfo
967 (type InternationalString) of OtherInformation in the Scan Request PDU.
968 The result set is identified in the otherinformation by the new OID:
969 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
970 This allows for scan in result set and faceted search . Zebra did some
971 of this in the APT term using attribute type 8 and value being result
972 set. Using the OtherInformation approach for this is cleaner and easier
973 to work with in proxies and the like. This facility can be used in
974 yaz-client using new command setscan which takes a result set as first
975 argument, start position (APT) as second.
977 Changed decoding of SRU XML packed records to deal with servers that
978 have recordData with XML data with multiple root nodes. Also make
979 comparison for recordPacking case insensitive. Again, one server
980 returns "XML" where others return "xml".
982 For SRU responses allow Content-Type application/xml as well as text/xml.
986 Fixed bug in character set conversion of BER strings. Bug introduced
991 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
993 For OID class, use oid_class consistently.
995 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
998 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
999 character set for bibliographic information interchange". By Giannis Kosmas.
1001 Added documentation on new OID API.
1003 --- 3.0.0 2007/05/02
1005 Changes to generic frontend server interface: added new member
1006 'query_charset' for bend_initrequest structure. A backend init handler
1007 should set this member to its native character set for query terms.
1008 When defined, the frontend server logic will announce this character set
1009 to a client if the negotiationModel bit is set by the client. All server
1010 implementors are encouraged to specify this. If a backend server does not
1011 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1013 Added CCL utility to remove terms (stop words) from resulting RPN
1014 tree. This is handled by functions with prefix ccl_stop_words_ .
1016 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1017 terms in RPN queries.
1019 Clean-up the CCL API. Moved some internal structures from ccl.h to
1020 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1021 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1022 This is replaced by ccl_parser_find_str which takes a string instead.
1024 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1025 libyaz.la is the core of YAZ except the generic frontend server and
1026 does not depend on POSIX threads anymore. libyaz_server.la is the
1027 generic frontend server facilities and uses POSIX thread functionality
1028 if available. The libyaz.la no longer depends on POSIX threads because
1029 the number of global structures is limited. NMEM no longer re-uses blocks
1030 between threads ; it simply free's memory immediately but allocates in
1031 "large" chunks as usual. We don't expect any performance penalties
1032 because of this. The yaz_log system is still using a global log_level so
1033 caution must be taken when modifying it with yaz_log_init_.. +
1034 yaz_log_mask_str. This, however, should not cause any trouble because
1035 these functions are called during initialization of application code
1036 anyway. `yaz-config --libs server` returns libs for server applications;
1037 `yaz-config --libs` returns libs for non-server applications.
1039 New OID database - with public definitions in oid_db.h. Removed old OID
1040 database including the head oid.h and definitions such as enum oid_value
1041 and struct oident. The new OID database uses the same string names as
1042 before but the 'protocol' is gone. There are now only two representations
1043 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1044 converts from string to OID; functions with prefix yaz_oid_to_string
1045 converts the other way.
1047 Change to emit_term() in CQL-to-PQF query translation: when a term has
1048 the /regexp relation modifier, do not process it for leading and
1049 trailing "^" and "*", which have quite different meanings in regular
1052 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1053 write handlers no longer carries a 'last' parameter. This will make
1054 yaz_iconv flush "less" characters. A flush is performed by call to
1055 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1057 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1058 removed, because function yaz_query_to_wrbuf does the same.
1060 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1061 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1063 Deprecated MARC utility functions removed.
1065 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1068 Branch split: YAZ_2_1_55_branch
1070 --- 2.1.54 2007/03/16
1072 Fix to ZOOM-C so that transparent reconnection is properly handled on
1073 connections that are in asynchronous mode.
1075 Fixed compilation on OpenBSD 4.0.
1077 Large strings in GRS-1 records are now properly displayed in yaz-client.
1079 Added character conversion support for "advancegreek"; based on patch from
1082 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1083 sequence is met. Before the error was not set so it would be unknown.
1085 Adjust yaz-marcdump MARC reader so that it skips until record separator
1088 --- 2.1.52 2007/03/07
1090 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1091 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1092 fd_set structure used as a bitmask for the FDs to be selected on.
1094 Using ACX_PTHREAD macro to check for POSIX threads.
1096 Fixed have-vsnprintf check.
1098 --- 2.1.50 2007/02/23
1100 Fixes for configure on BSD. Bug #900.
1102 Added snprintf/vsnprintf wrappers for systems that don't have
1103 limits (heavens forbid).
1105 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1106 created before all previous tasks were completed and removed from the
1107 task queue, the new task could be removed by a mistake.
1109 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1111 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1113 Fixed bug #832: Problem with MARC/charset in yaz-client.
1115 Fixed bug #668: save command line history for yaz-client.
1117 Fixed bug #830: pkg-config support.
1119 --- 2.1.48 2007/01/23
1121 Extended ZOOM result set options with two options that may be read by
1122 a client: resultSetStatus and presentStatus with values as specified for
1124 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1126 Fixed bug #827: Using SSL fails on Debian etch.
1128 Fixed bug #826: Weird looking chars for set of MARC records.
1130 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1131 that is treated as an ItemOrder with itemRequest being an XML document
1132 external. The value of "doc" is the content.
1134 Extended the GFS search facility. New member of bend_search_rr
1135 'estimated_hit_count' signals that hits is known to be an estmate
1136 (higher or lower than real hit count). New member 'partial_resultset'
1137 signals that the search was partial (hit count is lower or equal than
1138 real hit count). For Z39.50, the information is stored in resultSetStatus
1139 member of SearchResponse APDU. For SRU, the information is signalled
1140 via SRU diagnostic 59: "Result set created with valid partial results
1143 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1145 --- 2.1.46 2007/01/13
1147 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1149 Added ZOOM_connection_peek_event.
1151 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1152 the following new functions:
1153 ZOOM_event_nonblock, ZOOM_connection_process,
1154 ZOOM_connection_get_{socket,mask,timeout},
1155 ZOOM_connection_fire_event_{timeout,socket}.
1156 The existing blocking event handler, ZOOM_event, is a wrapper for the
1157 + blocking ZOOM_event_sys_{poll,select}.
1159 Implemented function ccl_xml_config which parses XML version of CCL
1160 configuration (bug #798).
1162 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1164 Added timings utility (yaz/timing.h)
1166 --- 2.1.44 2007/01/03
1168 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1171 Fixed bug #779: Rotation of apdu.log fails.
1173 Fixed for character set conversions:
1174 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1175 Honor G1 set in MARC-8 decoding.
1177 --- 2.1.42 2006/12/17
1179 Fixed bug #775: char conversion does not handle Alternative UTF-8
1182 Implemented function yaz_marc_read_line which parses MARC line format
1183 records. There is a wealth of formats out there. So far, this function
1184 reads line records produced by yaz_marc_write_line.
1186 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1187 more generic and easier to remember(!) options: -i format and -o format
1188 which specifies input format and output format respectively - where
1189 format is one of "marc", "marcxml", "line", "marcxchange".
1191 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1192 does not print anything except warnings for records.
1194 For yaz-marcdump, added support for MARC split into files (-s) with a given
1197 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1198 spec, at http://www.loc.gov/standards/sru/record-update/
1199 This has changed the binary layout of the following structs:
1200 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1201 bend_update_rr . Patch by Ko van der Sloot.
1203 Added GFS utility function bend_assoc_is_alive which returns 1 if
1204 association is still alive (client is connected); 0 otherwise (client
1205 closed connection). This allows busy servers to stop working for
1208 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1209 been a separate piece of software. This version of ziffy has been modified
1210 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1212 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1214 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1215 Client code may now interrogate options such as "init_opt_sort" to
1216 find out whether the server claims to support various options.
1218 --- 2.1.40 2006/11/27
1220 Added utilities yaz_{set,get}_esn to set/get element set name from
1223 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1224 of YAZ and has been so since YAZ 2.1.10.
1226 Implemented ZOOM_record_error which returns error information for
1227 record (surrogate diagnostic).
1229 --- 2.1.38 2006/10/31
1231 Updates for SRU Update by Ko van der Sloot:
1232 1. Changed name from "operation" to "action"
1233 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1234 versions in the code, marked as 'backward compatible'.
1235 3. Added diagnostics for SRU Update.
1237 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1239 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1241 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1243 For GFS, fixed problem with SRU diagnostic 'First record position out of
1244 range' being issued for 0 hits.
1246 zoomtst10 part of Windows Build.
1248 --- 2.1.36 2006/10/13
1250 Implemented yaz_filepath_comp which splits a path into file path
1251 components (required by Zebra 2.0.3+).
1253 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1254 BSD inspired license until now so this should not have any real impact on
1255 anybody. See http://www.opensource.org/licenses/bsd-license.php
1257 Fixed bug #687: Missing log lines.
1259 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1262 Fixed bug #689: SRU diagnostics to be added.
1264 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1265 whether a connection is idle (no more work do do).
1267 --- 2.1.34 2006/10/04
1269 Change type of optval from long to int for invocation of setsockopt with
1270 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1272 Added support for specifying the max log file size for the Generic
1273 Frontend Server. The size is given with option -r.
1275 --- 2.1.32 2006/09/21
1277 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1279 --- 2.1.30 2006/09/17
1281 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1284 Fixed bug in Generic Frontend Server that could cause a server to stop
1285 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1287 For the generic frontend server, the maximum record size is used as maximum
1288 size of incoming packages (SRU + Z39.50). The value until was previously
1289 only used in Z39.50 Init negotiation and, later, in a session controlled
1290 sizes of records returned. This is controlled using -k option. It can be
1291 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1293 --- 2.1.28 2006/09/04
1295 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1298 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1300 New option for yaz-marcdump -lpos=value which allows setting a portion
1301 of MARC header to a certain value.
1303 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1305 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1306 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1308 --- 2.1.26 2006/08/15
1310 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1313 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1315 --- 2.1.24 2006/08/08
1317 Fixed MARC ISO2709 encoding routines to deal with character set
1320 Minor changes to GFS logging. Database included in search request log
1323 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1324 cached/multiple records.
1326 Shared libraries are built by default on Unix+configure.
1328 Changed cql2pqf transformation to use a different evaluation order. The
1329 new order is: always, relation, structure, position, truncation, index
1330 and relationModifier. Old order was: always, relation, relationModifier,
1331 structure, index, position, truncation. Note that the the latter ones
1332 override former ones for identical attributes.. The new scheme means that
1333 it is possible to override any existing attribute with a relationModifier.
1334 And also that it is possible to override everything for the index rule
1335 (except the ones listed in relationModifier). No order is perfect but this
1336 one, we believe, covers more real cases.. The "always" should have been
1337 called "default", since the attributes there can be overridden with all
1340 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1341 compilation phase, but also for yaz-config --cflags output. This allows
1342 us to have public headers with Libxml2 stuff in them . It should also,
1343 eventually, make Libxml2 checks redundant in packages using YAZ, such
1346 --- 2.1.22 2006/06/15
1348 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1349 stored in uri, message and details.. Previously diagnostics were stored
1350 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1351 compatibility.. but he's probably the only one affected, so.
1353 Added support for CCL, compiled on the client side, in ZOOM-C. This
1354 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1355 input; the resulting query objects can be used for for searching with
1356 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1358 YAZ' configure searches for OpenSSL by default.
1360 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1361 SL_CTX_use_certificate_file. See
1362 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1363 for more info. Thanks to Ko van der Sloot.
1365 --- 2.1.20 2006/06/02
1367 Bug #600: SRU GET, POST support for yaz-client. Introduced
1368 command 'sru' which selects method SOAP/GET/POST.
1370 Allow missingValueAction to be specified for the sortspec string -
1371 function yaz_sort_spec. By default, the missing value action is null.
1372 Use ! to specify "abort". Use = followed by stringvalue to specify default
1375 Ensured that Present-handler (if defined) is called in GFS before any call to
1376 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1377 searchRetrieve requests.
1379 Documentation for YAZ is now based on the Docbook XML/XSLT using
1380 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1381 is no longer depending on jade/openjade or docbook-to-man scripts.
1382 PDF is no longer part of the distribution - but can optionally be
1383 made using DSSSL/jadetex or FOP.
1385 Added retrieval handling support in Generic Frontend Server to support
1386 conversion between MARC/XML as well as XSLTtransforms. See
1387 etc/yazgfs.xml for an example.
1389 Added Authentication support to Generic Frontend Server in SRU
1390 mode. Authentication using HTTP Basic is supported, as is the use
1391 of 'x-username' and 'x-password' parameters in the request itself.
1393 Added support for a new character set MARC8s identical to MARC8 except
1394 that it converts combined characters to single Unicode characters in the
1395 Latin-1 range (when possible).
1397 --- 2.1.18 2006/04/24
1399 ASN.1 compiler 0.4: generates brief Doxygen file header for
1400 generated .h/.c files.
1402 Utility yaz_iconv now supports conversion to MARC-8.
1404 New facilities for the MARC module. The reading - and writing of
1405 content are separate methods for the yaz_marc_t handle. The following
1406 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1407 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1408 format). Write functions have prefix yaz_marc_write_.. The existing
1409 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1410 available. Removed support for OAI-MARC and simplexml (not the
1411 simplexml from PHP5).
1413 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1414 to be returned for this connection.
1416 --- 2.1.16 2006/03/31
1418 Allow multiple languages and charsets to be specified with
1419 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1420 negcharset iso-8859-1,utf-8
1422 Translation of proximity nodes from CQL into PQF now works.
1424 Moved to automake 1.8, 1.9.
1426 Added function yaz_log_set_handler which allows a log handler to be
1427 installed. This handler will be called for all log messages. Output
1428 to file is also produced; but that can be disabled by passing NULL
1429 fname to yaz_log_init_file.
1431 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1433 For SRW (including GFS), accept application/soap+xml as content-type
1436 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1437 produces NO stylesheet reference even if a default stylesheet is specified
1440 --- 2.1.14 2006/03/14
1442 Updated Windows package to include yazd.dll + yazd.lib for the
1443 Development component.
1445 If the environment variable YAZ_LOG is set, then it is used as a
1446 string indicating the default level of logging to use if not
1447 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1448 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1449 used as before. So, for example, to omit warnings from YAZ logging,
1450 export YAZ_LOG=-warn
1452 cql_transform() now map structure and other attributes before indexes,
1453 so that index-specific structures and other attributes can override
1454 defaults. So now a combination of mapping specifications such as:
1456 index.dc.date = 1=date-modified 4=5
1457 does the right thing.
1459 cql_transform() now also respects the "always" mapping specification,
1460 which establishes an initial set of attributes to be used for all
1461 terms except where overridden by more specific attributes associated
1462 with the index, relation or modifier.
1464 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1465 which mode to use; one of "post", "get" or "soap" (SRW, default).
1467 Fixes for yaz_iconv routines: changed trie-based character set conversions
1468 to use only non-negative values for bit fields due to Sun's C compiler not
1469 supporting negative values.
1471 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1472 sequences where not read correctly. Fix by Rustam Usmanov.
1474 Updated win/makefile to use options, settings which makes things
1475 compile with VS C 2005.
1477 --- 2.1.12 2006/02/01
1479 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1481 In ZOOM socket code, use select instead of poll on MacOSX.
1483 ZOOM-C now support client-side compilation of CQL into RPN that is
1484 sent to the server, enabling CQL to be used against all Z39.50
1485 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1486 ZOOM_query object, and submit it using ZOOM_connection_search().
1487 The CQL-to-RPN translation uses a configuration file, the name of
1488 which must be specified in the Connection's "cqlfile" option.
1490 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1491 function, which takes as its start-term parameter a ZOOM_query object
1492 (which may have had either CQL or RPN set into it).
1495 --- 2.1.10 2005/11/29
1497 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1498 GFS to support this as well. Backend handler, bend_srw_update, does the
1499 update work. Code contributed by Ko van der Sloot.
1501 Allow retrieval of Search Result-1 information in ZOOM by the use of
1502 options that are attached to a result set. ZOOM documentation updated
1505 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1506 UTF-8 conversion. Patch by Raj Patel.
1508 Added option -m to GFS to control formatting of timestamps in log file.
1510 Added 'exit' as synonym for 'quit' in yaz-client
1512 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1513 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1514 for the new members. Patch by Ko van der Sloot.
1516 Added support for SRU POST. It is supported for content-type
1517 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1519 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1520 Instead make the library libyaz.la multi-threaded. Threading as a whole
1521 can still be disabled by configure option --disable-threads. Previosly,
1522 with older GLIBCs there were problems with MT libs under Apache. This
1523 has now been fixed a long time ago.
1525 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1528 CQL module modified to be case insensitive for relations/indexes/operations.
1530 Fixed bug in CQL transform code: incorrect value relationModifieder
1533 Added 'show all' command for yaz-client which retrieves all results
1536 Added new yaz-client, xmles, which takes a (private) OID and
1537 a document to be sent as an extended service request.
1539 Describe new yaz-client commands wait_response and set_auto_wait.
1541 Increase TCP/IP listener backlog from 3 (which I am guessing was
1542 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1543 that the socket will queue as many incoming connections as it's able
1544 to handle ongoing connections. In other words, it will never now
1545 refuse a connection that it would be able to handle merely because
1546 it's not got around to accepting() enough of the pending connections
1547 yet. This is the behaviour anyway under Linux, where the listen()
1548 argument is ignored; but not under BSD and on systems such as
1549 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1550 YAZ-based servers should now be uniform across operating systems in
1553 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1554 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1555 This allows yaz-marcdump to read large MARC batches (>2 GB).
1557 Modified all YAZ source files - except the source which is auto-generated
1558 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1561 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1562 corresponding to the existing *_setl() function. These allow option
1563 values containing arbitrary valuues.
1565 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1566 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1567 except that it returns an indicator of whether or not the sort
1568 criterion was accepted (0 for OK, -1 for invalid).
1570 --- 2.1.8 2005/06/07
1572 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1573 MARC output rather than returning "new" buffer.
1575 yaz-client warns about unknown init options.
1577 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1579 --- 2.1.6 2005/05/24
1581 Added support for SRW sort in Generic Frontend Server. Patch
1582 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1583 sortKeys - or NULL if none is provided.
1585 Fixed bug #307: It was impossible to specify indefinite/no timeout
1586 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1589 Added support for multiple languages and charsets to be specified in
1590 ZOOM. Each charset/language is separated by a blank. If negotiation is
1591 in effect in init-response, Option
1592 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1593 Code based on patch by Vasiliy Osadchuk.
1595 Fixed bug #306: infinite recursion that occurred when calling
1596 yaz_log_level_init as the first call (before other log level or
1599 Fixed bug in scan handling in front end server: if preferred-Position-In-
1600 Response was non-present, a NULL pointer referece was performed.
1602 --- 2.1.4 2005/04/26
1604 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1605 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1606 now defined for all those error codes. So instead of putting 109 in
1607 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1608 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1610 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1613 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1615 Program yaz-client now exits and produces an error message if multiple
1616 Z39.50 servers are specified on the command line (none or one allowed
1619 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1622 --- 2.1.2 2005/03/16
1624 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1626 Fixed bug #272: Preserve spacing for CCL terms.
1628 --- 2.1.0 2005/03/14
1630 Added support for virtual hosts and multiple backend servers for
1631 the YAZ frontend server. The configution is XML based and
1632 support specificition of CQL to RPN mappings and explain information.
1633 See section "Virtual Hosts" in the YAZ manual.
1635 Extended OPAC display utility. OPAC display utility renders
1636 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1637 to supplement yaz_marc_decode_wrbuf.
1639 Fixed a bug in MARC decoder that could caused it to crash for some
1640 invalid MARC records. More diagnostics and warnings where added in
1641 XML output (warnings, etc are stored in comments).
1643 --- 2.0.34 2005/02/08
1645 Fixes for UNIX domain sockets. Bug #261.
1647 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1649 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1650 Added yaz_marc_subfield_str which defines subfield lead string which is
1651 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1652 yaz_marc_endline_str which defines end of fields string used in
1653 YAZ_MARC_LINE format. Default string is newline.
1655 Experimental support for MarcXChange. This format can be produced
1656 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1657 http://www.bs.dk/standards/MarcXchange.xsd
1659 Added yaz-client commands scansize that sets maximum number of
1660 entries to be returned by scan.
1662 --- 2.0.32 2005/01/11
1664 Added support for SRW scan in yaz-client and Generic Frontend Server.
1666 * Added whereInList member to SRW Scan Term.
1668 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1670 Fixed NMEM system to return aligned blocks on the smallest boundaries
1671 that are suitably aligned for all possible types on the particular
1672 architecture YAZ is being built for.
1674 --- 2.0.30 2005/01/04
1676 Fixed numerious warnings that was issued with newer versions of GCC.
1678 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1679 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1682 Make YAZ Generic Frontend Server slightly faster.
1684 Enhance (and reduce) logging for Generic Frontend Server.
1686 Revert YAZ log system so that it flushes every write operation
1687 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1689 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1690 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1691 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1692 will effectively disable old definitions.
1694 --- 2.0.28 2004/11/09
1696 Added yaz_log_time_format which specifies log format using
1699 Added yaz_log_module_level which returns mask for a module. Value
1700 is non-zero mask a if module is enabled; zero if disabled.
1702 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1703 in include/yaz/cql.h.
1705 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1707 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1709 Fixed bug #172: RPM builds does not enable SSL.
1711 Doxyfile.in part of dist. Doxyfile generated by configure.
1713 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1714 are given and the corresponding component does not exist.
1716 Extend CCL documentation in YAZ reference. Describe r=r.
1718 --- 2.0.26 2004/10/01
1720 Fixed MARC->MARCXML conversion to properly deal with
1721 fields, subfields, indicators having non-ASCII characters.
1723 Fixed MARC->MARCXML conversion so that ASCII control characters
1724 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1727 Added YAZ GFS support for conversion from Z39.50 surrogate
1728 diagnostics to SRW surrogate diagnostics.
1730 Bug fix: YAZ GFS did not return schema in explainResponse.
1732 --- 2.0.25 2004/09/30
1734 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1735 now converts recordSchema to elementSetName as well as schema URI.
1737 Fixed bug in COMSTACK that prevented HTTP request packages from being
1740 --- 2.0.24 2004/09/29
1742 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1743 does not require white-space before and after the dash in a range, e.g.
1744 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1747 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1748 due to new GCC removing "redundant" code.
1750 Added yaz-client commands scanpos and scanstep that sets preferred
1751 position and step-size for scan.
1753 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1755 Added CCL utility ccl_qual_buf which parses one or more CCL
1756 spec lines in a buffer.
1758 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1759 of name and value - ignoring empty lines and comments.
1761 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1763 Added odr_get_element_path which returns current element path for an
1764 ODR handle. This utility is useful in error handling or user-defined
1767 Added ODR_PRINT utility odr_set_stream which is is a more generic
1768 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1769 to a write function and pointer to close function. The close function - if
1770 non-NULL - will be called during odr_destroy.
1772 Fixed bug in CCL parser where truncation char was not removed from
1773 right side when truncation=both was in effect.
1775 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1778 --- 2.0.23 2004/08/11
1780 Fix buffer overrun in CQL parser when dealing with proximity (%).
1782 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1783 to UTF-8/UCS conversion is now only based on codetables.xml.
1785 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1787 --- 2.0.22 2004/08/06
1789 Add support for more "commit changes" in ZOOM (uses Extended Services).
1791 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1794 Yet another small fix for configure of SSL.
1796 --- 2.0.21 2004/05/14
1798 Fix SSL libs for configure when --with-openssl=DIR is given.
1800 --- 2.0.20 2004/05/10
1802 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1804 SSL comstack now uses yaz.pem certificate file on server side
1805 by default. Certificate filename can be configured by calling
1806 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1808 Fix bug regarding multiple calls to ZOOM_connection_connect.
1810 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1812 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1813 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1815 ZOOM now allows inspection of X509 peer certificate for verification.
1816 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1818 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1819 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1820 as "modular" but it simplifies things.
1822 Added cs_get_peer_certificate to that returns peer X509 PEM.
1824 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1825 NULL if SSL is unavailable.
1827 Documentation about MARC decoding tools.
1829 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1831 --- 2.0.19 2004/03/30
1833 Rename CHANGELOG to NEWS to follow GNU style packing.
1835 Fix bug with missing initialization of member in init_diagnostics.
1836 This bug affects threaded version of GFS server.
1838 --- 2.0.18 2004/03/20
1840 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1843 Ensure zlib.dll is packed with Windows install.
1845 --- 2.0.17 2004/03/17
1847 Fix encoding of xsd:string to use text instead of CDATA.
1849 Fix endless loop in CQL parser with unbalanced ".
1851 Use a more compact way to store MARC-8 conversion tables.
1853 --- 2.0.16 2004/03/16 Debian only
1855 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1858 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1863 --- 2.0.15 2004/03/01
1865 Another fix for decoding of XML packed records.
1867 --- 2.0.14 2004/02/25
1869 Fixes for Chunked encoding. White space not ignored after length spec.
1871 Update NS and use default NS for SRW diagnostic elements.
1873 --- 2.0.13 2004/02/23
1875 Implement ZOOM_resultset_cache_reset which resets record cache.
1877 Implement ZOOM_resultset_sort which sorts a result set.
1879 Implement chunked HTTP transfer.
1881 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1883 --- 2.0.12 2004/02/16
1885 Added member 'schema' to bend_explain_rr structure so that backend
1886 can specify explain record identifier. Defaults to Zeerex 2.0.
1888 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1890 --- 2.0.11 2004/02/16
1892 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1895 Added init command for yaz-client which sends "extra" init request.
1897 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1898 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1900 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1902 Make ZOOM error code for "invalid query".
1904 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1906 --- 2.0.10 2004/02/05
1908 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1911 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1913 Added option -p <file> to make Generic Frontend Server to write PID file.
1915 Added option -D to put Generic Frontend Server in background on its own.
1917 Make ZOOM C recognize option "password". If unset, "pass" is used
1918 (for backwards compatibility).
1920 Fixed a bug in Generic Frontend Server that could make it crash if a
1921 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1924 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1925 Must be issued before open, in order to be in effect.
1927 --- 2.0.9-6 2004/01/12 Debian/Windows
1929 Make the SRU server more picky WRT unknown params, etc.
1931 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1933 New YAZ client command, options, that sets Z39.50 options.
1935 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1936 options from a string of tokens (one token for each option bit).
1938 Update SRW diagnostic code messages.
1940 --- 2.0.9-5 2004/01/07 Debian/Windows
1942 Handle user defined stylesheet for SRW/SRU.
1944 --- 2.0.9-4 2004/01/06 Debian/Windows
1946 Fix bug in decoding of Content-Length.
1948 --- 2.0.9-3 2004/01/06 Debian/Windows
1950 Fix a bug with decoding of XML packed records.
1952 --- 2.0.9-2 2004/01/05 Debian only
1954 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1956 Fix bug in SRW/SRU diagnostics decoding.
1958 --- 2.0.9 2004/01/05
1960 Fixed bug in Generic Frontend Server which could drop records exceeding
1961 preferred message size. Reported and fixed by Irina Dijour.
1963 Fixed calculation of package size for structured records in Generic
1964 Frontend Server. Reported and fixed by Irina Dijour.
1966 Fixed namespace for SRW/SRU diagnostics.
1968 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1970 --- 2.0.8 2003/12/22
1972 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1973 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1976 CQL changes to reflect recent changes to the specification:
1977 * Documentation talks about context sets instead of index sets.
1978 * Documentation talks about indexes instead of qualifiers.
1979 * The CQL-to-PQF transformer's configuration file now uses
1980 "index.set.name = <attributes>" instead of the old form
1981 "qualifier.set.name = <attributes>". (Both forms are still
1982 understood but the latter is deprecated.)
1983 * CQL terms with no explicit index specified are now interpreted as
1984 cql.serverChoice instead of srw.serverChoice (which of course
1985 behaves exactly the same.)
1987 --- 2.0.7 2003/12/16
1989 MARC conversion can now generate ISO2709 output in another
1990 character set. yaz-marcdump uses this facility if you invoke it
1993 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1994 functions from there can be used from C++.
1996 --- 2.0.6 2003/12/04
1998 Frontend server now transfers memory from decoded packages to stream
2001 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2002 references to show up.
2004 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2005 the ZOOM Abstract API. The older names for the same options are still
2006 also supported for the benefit of old applications.
2008 ZOOM-C supports "implementationId" and "implementationVersion" options
2009 to go along with "implementationName". These allow the user code to
2010 specify identification strings to be sent to servers.
2011 Add OID for the new ExtLite attribute set.
2013 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2014 as requested/supplid by Ere Maijala <ere@atp.fi>
2016 For generic frontend server, reverse the order of
2017 "toolkit-supplied / application-supplied" strings sent as implementationId,
2018 Name and Version. Also, remove the spaces around the slash. This brings
2019 the GFS in line with the behaviour of ZOOM-C on the client side.
2021 Add function ZOOM_scanset_display_term.
2023 yaz-client shows scan displayTerm if present.
2025 Utility yaz-iconv is now installed by default along with the man page
2028 Extend configure check for OpenSSL to use pkg-config where available (such
2031 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2032 server to specify uid/gid/mask for socket using the format
2033 unix:[user=uid,][group=gid,][umask=mask,]file=path
2034 If file= is omitted the existing format is assumed, e.g.
2036 in which case the mask is 0666 (rw for everybody).
2038 Major restructure of YAZ source. All source in libyaz is in src directory.
2039 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2040 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2042 Added man page for utility yaz-marcdump (used to be called marcdump).
2043 yaz-marcdump is installed by 'make install'.
2045 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2046 of incoming package failed.
2048 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2050 Change prototype of odr_perror: add const to message string.
2052 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2054 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2055 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2056 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2057 DNS lookup. There should not be any compatibility problems with this
2058 assuming that blocking=1 or 0 is used.
2060 Fix bad reference in UNIX comstack in function cs_addrstr.
2062 Fix for compilation on AIX.
2064 The generic front-end server (server/seshigh.c) now supports returning
2065 Init diagnostics to the client in User-information-field, in
2066 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2069 --- 2.0.4 2003/09/04
2071 Allow any CQL relation (not just all,any,exact,scr).
2073 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2074 that features the same UI.
2076 Implemented command update0 in YAZ client which is equivalent to
2077 update but uses old of Ext Update ASN.1.
2079 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2080 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2081 Previously no OID was used for this info.
2083 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2084 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2085 returns 'malformed search term' otherwise.
2087 SortResponse member resultCount now set to NULL in sort handler of
2090 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2093 Add three new utility functions for translating OIDs between various
2094 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2095 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2096 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2097 char *oid_to_dotstring(const int *oid, char *oidbuf);
2098 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2100 Reverted modifications for ES Update definition for z_IU0Update
2101 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2102 is back to YAZ 2.0.2.
2104 String value attributes for CCL parser.
2106 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2107 which their FirstSearch server returns in Init responses, sometimes
2108 carrying useful diagnostic information when Init fails. This has the
2109 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2110 "z39.50/oclcui.asn", where its definition is somewhat different from
2111 what OCLC document on their web-site, as required to interoperate with
2114 Support for anonymous authentication in yaz-client. Use the command
2117 * Fix the OID of the Index Data-local "admin" Extended Service from
2118 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2119 the 1000, which indicates a locally-defined OID, was a mistake.
2121 --- 2.0.3 2003/06/20
2123 Fix CCL directive @case handling so that it affects string match for
2124 both CCL keywords and qualifiers.
2126 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2127 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2128 Decoder has been updated with ASN.1 changes as listed in
2129 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2130 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2131 z_IUUpdate, remains unchanged.
2133 ZOOM_record_get may now return a record in a specific character set.
2134 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2135 "from" is the character set of record as returned by target. "to" is
2136 the character set to be returned. If omitted, "to" is UTF-8.
2138 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2140 New ODR utility, odr_getelement, which returns name of element for
2141 which encoding/decoding failed.
2143 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2144 in cases where a required element was omitted.
2146 Bug fix: some MARC8 sequences were not converted.
2148 New ZOOM option "step" which specifies number of records to be
2149 retrieved in one chunk. Used in conjunction with "start" and "count".
2151 SRW support for yaz-client. Use scheme http: to use it, e.g.
2154 yaz-client no longer does (un)intelligent character set conversions
2155 by default. Can be enabled with charset and marc_charset commands.
2157 xmalloc trace fix for 64-bit systems such as DEC alpha.
2159 Solaris 2.6 compile fix.
2161 New function, cql_strerror() translates SRW error codes, as returned
2162 by cql_transform_error(), into human-readable English strings. Used
2163 in yaz-client diagnostics when appropriate.
2165 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2166 converts it into a type-1 query which is sent to the server. This
2167 makes CQL available for use with all Z-servers, as opposed to the tiny
2168 minority that can handle CQL queries themselves.
2170 --- 2.0.2 2003/04/28
2172 New Debian package layout similar to the Redhat Package layout.
2174 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2175 and search result respectively.
2177 --- 2.0.1 2003/04/25
2179 Redhat package is now several packages: libyaz (runtime libraries),
2180 libyaz-devel (development and documentation, and yaz (utility programs).
2181 Package spec file by Morten Bogeskov.
2183 New member 'schema' in struct bend_fetch_rr which the name of requested
2184 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2185 handler MAY set this to reflect the schema of the returned record.
2187 New member 'display_term' in struct scan_entry. GFS now sets member entries
2188 and allocates scan entries to be filled by user scan handler. In previous
2189 version, entries member was allocated by the scan handler. That still works,
2190 but the GFS will ignore member display_term - assuming it was NOT set by
2191 the handler. The fact that the GFS now allocates the entries both allows
2192 for new members and makes a scan handler easier to write.
2194 Fix CQL lex buffer overflow.
2196 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2197 SRU default recordPacking is string.
2199 SRU protocol support for frontend server.
2201 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2203 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2205 Added scan for the ZOOM shell (zoomsh).
2209 * String Identifers for Schemas (Amendment 5).
2210 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2211 Old definition for schema
2212 Odr_oid *schema; /* OPT */
2217 Z_InternationalString *uri;
2218 #define Z_Schema_oid 1
2219 #define Z_Schema_uri 2
2222 * resultCount parameter to Sort Response (Amendment 1).
2223 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2225 Support for SRW 1.0 over HTTP. This is an optional feature and
2226 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2229 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2230 on the same port. SRW SearchRetrieveRequests are mapped
2231 to bend_init,bend_search,bend_fetch,bend_close.
2233 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2235 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2236 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2238 ZOOM connections are SRW based if schem http is used for hostname
2239 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2240 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2242 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2243 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2244 distance=n, order=true/false, relation=le, prox unit=word. If
2245 n is omitted, distance 1 is used.
2247 Fixed problem with C compiler include path in wrong order.
2249 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2250 on Solaris. Patch from Ko van der Sloot.
2252 New MARC decode API. All new functions operate on a yaz_marc_t
2253 handle. The most important new functions are: yaz_marc_create,
2254 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2255 decode and destroy respectively. Decoder can produce formats
2256 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2257 include/yaz/marcdisp.h.
2259 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2260 to UTF-8, UCS-32, wchar_t or Latin-1.
2262 * Prototypes for yaz_iconv_-functions moved to separate header
2263 include/yaz/yaz-iconv.h.
2265 Make a few private functions 'static' in unix.c. This prevents
2266 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2268 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2269 are set when Init Response is received.
2271 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2272 but returns diagnostic set as well.
2274 New function yaz_strerror which is a portable wrapper for
2275 strerror/strerror_r/GetLastMessage.
2277 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2278 is returned for MARC. If type is "oai", then OAI MARC is returned.
2280 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2283 --- 1.9.2 2002/11/26
2285 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2287 Fix bad race conditions on SIGTERM and terminate gracefully in
2290 Move retrieval (data1) module to Zebra since nobody seems to be
2293 Add GRS-1 render for ZOOM using same format as yaz-client.
2295 --- 1.9.1 2002/10/05
2297 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2299 Fix broken ESpec handling in data1 module.
2301 SGML reader parses comments and makes them part of the data1 tree.
2303 Added several type casts so that YAZ compiles as C++ code.
2305 ZOOM didn't handle PDU encoding failures properly.
2307 Added more Bib-1 diagnostics (approved extensions).
2309 GNU configure: better check for iconv.
2311 More portable use of accept, getpeername. Check for socklen_t. Use
2312 int/size_t if socklen_t is not defined.
2316 PQF parser rejects bad queries - including those with extra
2317 characters in them. PQF parser used to silently ignore that.
2318 Cleaner API for PQF added, which allows you to get detailed
2319 error information for bad queries (see yaz/pquery.h).
2321 Fixed bug in ZOOM_record_get for type "database".
2323 Implemented mini iconv library supporting conversions between
2324 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2326 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2328 --- 1.8.9 2002/08/20
2330 Fixed ZOOM C record cache so that preferredRecordSyntax and
2331 elementSetName is used to check for already fetched records.
2333 --- 1.8.8 2002/08/02
2335 Added three members in bend_initrequest structure to facilitate
2336 character set negotiation.
2338 Fixed a bug in frontend server that could cause indefinite
2339 loops under rare conditions.
2341 Revised character set utilities (charneg.h) so that encoding
2342 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2344 For PQF, directive @term <type> sets term type for Scan/Search.
2345 Here <type> is general, string, numeric, null. The term type
2346 is inherited - just like @attr.
2348 New call odr_set_charset that sets character set conversion for
2349 international-strings on a ODR stream. Prototype is:
2350 int odr_set_charset(ODR o, const char *to, const char *from);
2351 The InternationalString is still represented as C string in YAZ
2352 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2353 won't). On the protocol level, you can use any encoding.
2355 Support for UNIX sockets in ZOOM.
2357 Solaris recv sometimes returns errno == ENOENT. It is treated as
2358 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2360 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2361 both client and server. Code by Morten Bogeskov.
2363 --- 1.8.7 2002/05/22
2365 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2366 that they can be used directly from Visual Basic. You must recompile
2367 your windows APP if you're using ZOOM.
2369 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2370 Commands "lang" and "charset" sets language and character set respectively.
2371 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2372 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2374 Attributes from multiple CCL fields may be OR'ed rather than merged
2375 using directive "@field or". Fields are still merged by default -
2376 equivalent to "@field merge".
2378 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2381 Fixed bug in zget for parameter ExtendedServicesResponse.
2385 --- 1.8.6 2002/03/25
2387 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2389 Client displays USR.1:SearchResult-1 (hits per term).
2391 Additional Search Info for search in Generic Frontend Server.
2393 Fixed CCL parsing of "field=s".
2395 WIN32 installer - using the excellent NSIS software from nullsoft.
2397 Fixed CCL parsing of "field = - <number>".
2399 Added function yaz_marc_decode that decodes MARC for line mode
2400 display or XML (similar to that used by JZKit).
2402 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2403 Z39.50. But ISO/ILL was, however.
2405 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2406 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2408 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2409 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2411 --- 1.8.5 2002/02/03
2413 New YAZ client features: Command completion and new commands:
2414 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2415 Code provided by Jacob Poulsen.
2417 New call oid_trav, that visits all registered OIDs via callback.
2419 Function ZOOM_record_get now returns const char pointer rather than
2420 void pointer. It saves a lot of type casts.
2422 For YAZ client, command "auth" now allows you to set authentication
2423 in IdPass style. It is enabled when three tokens are given - order
2424 is user, group and password.
2426 Fix memory leaks in MARC record handling for ZOOM.
2428 New option for YAZ client, -k <kilobytes> that sets
2429 maximum record size. Similar to -k option for generic frontend
2430 server and yaz-ztest.
2432 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2434 Prefix query parser reports "fail" when bad attribute set is given.
2436 Fix in MARC decoder. Proximity logging. Fix for attribute set
2437 in scan handler for server. Patches by Shigeru Ishida.
2439 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2442 Configure option --with-openssl=<dir> now works when a directory is
2443 specified. Patch provided by Morten Bogeskov.
2445 New option for YAZ client, -u <auth>, that sets authentication.
2447 ZOOM fix: error information was sometimes "missing", since error
2448 was cleared/reset too when it shouldn't.
2450 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2452 --- 1.8.4 2002/01/04
2454 Scan for ZOOM API. New object ZOOM_scanset. New functions
2455 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2456 ZOOM_scanset_destroy.
2458 New ZOOM function, ZOOM_connection_last_event, that returns type
2459 of last event (such as "receive data", "send data", "apdu received",
2462 New ZOOM option, schema, that specifies schema for retrieval.
2464 New CCL feature. Qualifiers can be aliases for one or more
2465 other qualifiers (if more than one is given, OR is used).
2467 ZOOM uses named result sets if target supports it.
2469 Two new YAZ client commands: . (dot, which sources a script of YAZ
2470 client commands), and ! (to execute shell command.). Implemented
2473 Working on Debian packages.
2475 --- 1.8.3 2001/11/19
2477 YAZ client enables named result sets only if target supports it.
2479 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2481 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2482 with key="host" to get same result.
2484 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2485 Function Z3950_resultset_record(s) returns references to records
2486 "owned" by resultset. To become owner use Z3950_record_clone.
2488 Function z_ext_record handles Extended Services. Thanks to
2491 --- 1.8.2 2001/11/12
2493 CCL Parser fix: ignore token comma when dealing with and-lists.
2495 Documentation updates for COMSTACK.
2497 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2498 Changed prototype Z3950_records. For some functions, int parameters
2499 were changed to size_t.
2501 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2504 New MARC decode/display function, marc_display_exl, which properly rejects
2505 non-ISO2709 records. YAZ client uses it.
2507 --- 1.8.1 2001/10/29
2509 Fix bug: local attribute set wasn't set correctly in PQF strings.
2513 * Old Z39.50 codecs no longer supported.
2515 Added ZOOM C binding. See http://zoom.z3950.org/
2517 Renamed states for COMSTACKs to avoid confusion with events.
2519 Implemented cs_look and proper cs_rcvconnect.
2521 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2523 Configure detects POSIX threads on OpenBSD.
2525 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2526 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2528 When error is returned from present handler, non-surrogate diagnostic
2529 is returned in present response (and fetch handler is no longer called).
2531 * Minor adjustments to pquery parser (PQF). Token characters may be
2532 escaped by using backslash (C-style).
2534 PQF parser allows string attribute values to be specified. For @attr,
2535 non-numeric characters after the equal-sign are treated as strings
2536 (e.g. @attr 9=title).
2538 CCL trunction character may be defined (@truncation in file)
2540 * function zget_ExtendedServicesRequest sets waitAction to
2541 waitIfPossible (was wait).
2543 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2546 CCL operator names may be set in field definition files (CCL_bibset).
2547 See ccl/bib1 for an example.
2549 Fixes in ASN.1 compiler for C++ compatibility.
2551 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2552 and "op_or" to avoid conflict with C++.
2554 Fixed problem with GNU readline detection on Redhat 7.0.
2556 Added step-size for Scan backend handler.
2558 Fixed bug that made the frontend server crash when no attribute
2559 set was specified for scan.
2561 Front-end server automatically switches to original working directory
2562 when installed as an NT service. Previously -w had to be specified to
2565 Added extended attributes for retrieval module (data1), so that data1
2566 records carry d1_readXML/SGML attributes. d1_read also supports
2567 null-data rules ( <tag/>)
2569 On UNIX when POSIX threads are available, a separate library libyazthread
2570 is created. Programmers should link with that library and the yaz library
2571 when using threads. The reason for the split was that some applications
2572 on Linux, such as Apache, doesn't work well when using shared objects that
2575 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2576 (or any frontend server) in SSL mode by specifying ssl: followed by
2577 address. Only tested on UNIX.
2579 Added feature for CCL module. Virtual structure s=al or s=ol generates
2580 and-list and or-list respectively instead of phrase search.
2584 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2585 log_mask_str. This was done to avoid name conflicts with other libraries
2586 (such as other PHP extensions).
2588 Added raw OID member for preferred record syntax (request_format_raw)
2589 and returned record syntax (output_format_raw) for backend fetch method.
2591 Config file yaz-config now accepts options so that it returns specific
2592 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2594 Shared library support for UNIX using GNU libtool.
2596 * Modified backend interface. Request/Response struct's replaced by
2597 one read/write C struct. For example bend_fetchrequest and
2598 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2599 Every handler - even search has to be registered in bend_init
2600 handler. This means that the YAZ library no longer refers to
2601 external functions and it makes it possible to make the whole
2602 thing a single DLL/SO.
2604 Added Segment handler for backend server.
2606 Added Zmbol/Zebra administrative functions to YAZ client.
2608 Threaded frontend server on UNIX (when POSIX Threads are available).
2609 Starting the server with option -T enables multi-threading.
2613 Added configure option --enable-comp/disable-comp to control use
2614 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2615 located in sub directory asn.
2617 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2618 in ${exec_prefix}/bin along with the other programs yaz-client and
2621 GNU automake used to maintain makefiles.
2623 Added several OID's.
2625 Changed retrieval module so that we can load records with no abstract
2626 syntax defined. Tagpaths in these records are fully composed of string
2629 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2633 On UNIX, the generated makefile now supports a proper 'make install'.
2634 The prefix can be set via GNU configure to set the install location
2635 (default is /usr/local).
2637 * YAZ programs client and ztest were renamed to yaz-client and
2638 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2639 locations, such as /usr/bin,/usr/local/bin,etc.
2641 * YAZ Header files were moved from include to include/yaz. YAZ Header
2642 files are referred to as include <yaz/log.h> rather than <log.h>.
2643 The YAZ include path (-I ..) is therefore the same as before. Programmers
2644 should update their #include statements or use -Ipath/include/yaz
2645 instead. The main motivation for doing this change is that YAZ header files
2646 can be installed in "standard" locations /usr/include,/usr/local/include
2647 without introducing conflicts, since ALL YAZ header files are stored
2648 in subdirectory yaz (under /usr/include for example).
2650 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2651 rather than project/workspace files. We switched because project files
2652 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2655 Changed name of logging function, logf, to yaz_log, to prevent name
2656 clash with some math-log functions. The YAZ header log.h defines logf
2657 to yaz_log (#define) so there should be no incompatibilities by this
2660 Added bend_start/bend_stop handlers for server. These handler are
2661 called on start/stop of server. For windows they are called whenever
2662 a service is started/stopped.
2664 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2665 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2666 in util/yc.tcl. The auto-generated C code structures are, in a few
2667 cases, incompatible with the old decoders. There are differences in the
2668 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2669 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2670 The preprocessor variable ASN_COMPILED is defined when the compiled
2671 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2672 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2673 wish to use the old encoders/decoders you can specify --disable-yc
2676 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2677 version so that it supports both new - and old version of DB Update
2679 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2680 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2681 change. The name parameter can be set to 0 in which no name is specified
2682 for the construction. The macros odr_implicit and odr_explicit sets name
2683 parameter to zero for the construction involved. New macros
2684 odr_implicit_tag and odr_explicit_tag are similar to the others,
2685 except that a name parameter is added. For programmers' that don't use
2686 ODR they probably only need to change the call to z_APDU and z_External.
2688 Added access control facility by interfacing the TCP wrapper library.
2689 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2690 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2691 name of the daemon and enables the access control as specified in
2692 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2694 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2695 den Dool <H.M.vdnDool@kub.nl>.
2697 Added reference ID parameter to most functions in server API - refer
2698 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2700 Changed name of ccl library to libccl.a (was ccl.a).
2702 Fixed bug in decoder for Explain (Category TargetInfo).
2704 Added support for GNU readline in client. Thanks to Jacob Poulsen
2705 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2707 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2708 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2709 IMPLEMENTATION! This change was made to the development version before
2710 the ZIG decided to retract the amendment. If any users MUST be
2711 compatible with the original Update definition, PLEASE CONTACT US, and
2712 we will include a separate definition corresponding to the old Update
2713 ES. Note that because of the change to the ASN.1 of the
2714 TaskPackageRecordStructure we cannot define a single structure that
2715 will support both versions.
2717 * Added const modifier to buffer parameter for some ODR/BER encoding
2718 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2719 completeWAIS, odr_dumpBER.
2721 Fixed bug in client.c which caused a crash when a scanResponse didn't
2722 contain positionOfTerm.
2724 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2725 * will cause an error in a client if a non-YAZ target sends both a
2726 * list of Scan entries and non-surrogate diagnostics.
2728 Retrieval module enhancements. Tag sets may be typed in the reference
2729 to it. From the .abs-file the "tagset" directive takes a third optional
2730 integer type for the tag set referenced. From a .tag-file the "include"
2731 directive takes a third optional type as well. The old "type" directive
2732 in the tag set itself is still recognized but acts as the default type
2735 Backend interface change. Individual Scan terms returned from bend_scan
2736 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2737 in include/backend.h.
2739 Retrieval module enhancements. Multiple tag sets and attribute sets may
2740 be specified in abstract syntax specs. Revised the error/warning for
2741 logging messages reported by the retrieval module when reading the
2744 Object Identifier system (oid_..) changed. The API is backwards
2745 compatible but the oid-routines now allocates new OID's when needed.
2746 Raw OID's may be specified in oid_getvalbyname.
2748 YAZ now uses GNU configure to generate Makefile(s).
2750 * Minor changes in some of the member names of DeleteResultSetRequest and
2751 DeleteResultSetResponse. See include/proto.h.
2753 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2754 and added member 'languages' in TargetInfo (which was missing).
2756 Changed the way attribute sets are handled in the retrieval
2757 module. These are now cached, just like the abstract syntaxes
2760 Changed YAZ so that it links with compiled ASN.1.
2762 Added Explain-schema definitions and mapping routines. The following
2763 Explain categories have been implemented: AttributeDetails,
2764 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2766 Fixed minor bug in Windows version of Server Library.
2768 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2770 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2772 Added EXTERNAL: UNIverse Resource Report (non-standard).
2774 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2775 ENUMERATED and SET OF.
2777 * Added 'const' to some of the char pointer arguments for the
2778 functions, data1_read_node, data1_getelementbytagname,
2779 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2782 Fixed bug in data1_insert_taggeddata - the last_child member of
2783 parent wasn't initialised.
2785 * Changed data1_read_record and data1_read_node so that the supplied
2786 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2787 doesn't refer to any parts of the "SGML"-buffer.
2789 Fixed bug in server library (Windows version of statserv_remove).
2791 * Changed code so that it compiles as C++. The type definition
2792 of Odr_fun which is a member of Odr_arm was changed. The result is,
2793 that an explicit typecast is needed for the fun pointer when
2794 using Odr_arm - as in:
2795 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2797 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2799 Implemented the new structured date and time definition as approved
2800 by the ZIG. Added schemaId element to the specificTag in Espec-1
2801 (also approved at the last ZIG). Thanks to RVDM.
2803 Added some Object identifiers (RVDM).
2805 Changed the Update Extended Service (RVDM).
2807 Added command "refid" to client which specifies referenceId for
2808 the following requests.
2810 Implemented extended service handling for server. See ztest.c
2811 for an example as well as backend.h. New handlers are registerd
2812 in the Init handler.
2814 * Changed interface for sort in server.
2816 Added new members to statserv_options_block. It allows a server
2817 to read options from another source than just the command line. Thanks
2818 to Charles Woodfield.
2820 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2821 renamed to zboolean. Some C++ compilers complained about the name.
2823 Minor changes to gils.abs. Added index 's' (sort) on title
2824 and date/time-last-modified.
2826 --- 1.4pl2 1998/1/30
2828 Fixed bug in server library regarding inetd mode (-i). This bug
2829 was introduced by release 1.4.
2831 --- 1.4pl1 1998/1/29
2833 Added sort facility in client and backend server interface.
2835 Fixed problem with dependencies in Makefile(s).
2837 Fixed bugs for encoders/decoders of extended services and
2840 Implemented sub-tree feature for schemas. Sub-trees are
2841 referenced in *.abs-files. See explain.abs for an example
2842 of the use of this feature.
2844 Modified bib1.att; local attributes for ANY didn't include
2845 ANY itself (only affects use of the retrieval module).
2847 Fixed bug in plain SGML reader in function data1_read_node:
2848 tags with prefix "var" was incorrectly interpreted as variants.
2850 Added feature "sub-schemas" to enable references to - and definitions
2851 of - group of elements.
2853 * Removed member parent from type data1_element (in data1.h).
2855 Implemented function odr_nullval() that returns the value of
2858 * Removed member num_children from data1_node (in data1.h).
2860 Made NT service interface part of the server library. The
2861 function statserv_main uses the NT service when required and
2862 calls the statserv_start / statserv_close routines.
2864 Routine zget_SearchRequest and zget_PresentRequest fills
2865 resultSetName/Id member with "default" instead of "Default".
2867 Fixed memory leak in server. Request queue member wasn't freed.
2869 Fixed nmem_exit so that memory is freed.
2873 Revised the CCL parser utility to be thread safe.
2875 Added function, oid_ent_to_oid, to replace the function
2876 oid_getoidbyent, which is not thread safe.
2878 * Added nmem_init and nmem_exit to initialize and release
2879 NMEM resources. Function nmem_init should be called once in the
2880 initial thread before NMEM/ODR is used. statserv.c and client.c
2881 have been changed accordingly. The change was necessary to make
2882 NMEM thread safe. The NMEM memory pool is shared amongst threads
2883 in a process. Unix-based applications will still work fine without
2886 Added NT Services interface for the the Z39.50 (statserv) Server.
2887 Refer to the ztest.c source on the usage.
2889 Windows 95/NT port using MSVC5.0. Project files are included in the
2892 * Defined new 'global' handle for the retrieval (data1) system. The
2893 new handled, data1_handle, describes the state of the data1 system.
2894 This handle is passed as first argument to virtually all
2895 data1 related routines. The functions data1_create and data1_destroy
2896 creates and destroys a data1 handle respectively.
2898 Added ODR encode stream member to all backend request structures
2899 init, search, scan etc. This stream should be used to allocate all
2900 memory used for the response when thread safe operation is needed.
2902 Changed the comstack utility, cs_addstr, to be thread safe. The
2903 returned hostname string returned by the function is now part the
2906 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2907 function. The cs_straddr takes a COMSTACK handle as argument, so this
2908 function must be used after cs_create and before bind/connect.
2909 This function is thread safe.
2911 Moved test server to 'ztest' directory - generic server code still
2912 in 'server' directory.
2914 Made prefix query (pquery.c) utility thread safe.
2916 Added new function modifier YAZ_EXPORT to 'export' public DLL
2917 functions when using windows (see include/yconfig.h).
2919 Added definitions to the OID database (util/oid.c) (RVDM).
2921 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2923 Added call to ccl_rpn_delete in client program.
2925 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2926 release of RPN structure.
2928 Added support for C++, headers uses extern "C" for public definitions.
2929 With input from RVDM.
2931 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2932 Thanks to Ronald van der Meer (RVDM).
2934 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2936 Added support for private extensions to the OID database
2937 (oid_setprivateoids()). Thanks to RVDM.
2939 Added optional, physical ANY (key replication)
2941 Fixed null-reference problem in GRS-1 output filter.
2943 Proximity operator added to Prefix Query Format (PQF).
2945 In test client command "base" accepts multiple databases.
2947 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2951 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2953 Smallish bug-fixes in the new encoders/decoders (explain).
2955 Bug fixed in DeleteRequest.
2957 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2959 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2961 Added SOIF syntax (using private OID for now) to retrieval module and client.
2963 Added Update extended service.
2965 Added SearchResult-1 additional info structure.
2967 Added optional CCL (ISO8777) interpreter as separate module. Available
2970 --- 1.2 1996/6/10 (1st anniversary release)
2972 Added Summary record syntax. Lightly tested.
2974 Added OPAC record syntax. Untested.
2976 Added ResourceReport service encoders/decoders. Untested.
2978 Fixed bug in z_Unit - wrong tagging on unitSystem.
2980 Fixed bug in the DiagRecs decoder.
2982 Added options for max PDU size and session timeout to frontend-server.
2984 Added documentation of query-language parsers and other supporting utilities.
2986 [frontend-server] Added Attribute set to the bend_scanrequest API.
2988 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2989 surrogate diagnostics were generated.
2991 [retrieval] Allow multiple local values for attribute.
2993 [retrieval] Allow multiple attributes per element in .abs files. index type.
2995 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2997 --- 1.1pl2 1996/4/10
2999 Minor changes, mostly specific to Zebra's requirements (retrieval)
3003 Repaired bug in frontend server when running multiple listening
3004 endpoints in dynamic mode.
3006 z_External() now won't break if a known, ASN.1 value comes encapsulated
3007 in an octet-string. The value will pass through unmodified in an Odr_oct.
3009 Added a bit of code to the demo client to decode & display
3010 ASN.1-structured records represented in the octet-aligned branch of
3011 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3013 Added z_ext_getentbyref() to the ASN module. Doc updated.
3015 * Completed the SCAN definition in the ASN module. This may break SCAN
3016 code based on older YAZ-versions at compile-time. The fix is easy -
3019 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3020 under the SCAN definition. Remember to initialize this, server-people.
3022 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3023 that this does not extend to ODR and ASN.
3025 Comstack allows insertion of established socket (primarily for
3026 inetd-operation of servers). Doc updated.
3028 Front-end server can now start from the inetd in TCP mode. Doc
3031 --- 1.0pl4 1996/1/24
3035 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3036 the rank and record number.
3038 Adjustments to the frontend server.
3040 Fixed diagnostic BER dumper. It ignored the file argument.
3044 Various changes to retrieval module.
3046 Changed the union discriminators of the protocol files from enums to
3047 ints paired with #defines.
3049 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3052 *Changed operator in the RPN structure to 'roperator', again to avoid a
3055 Fixed problems in Explain decoders/encoders.
3057 --- 1.0pl2 1995/12/6
3059 Memory bug in log module fixed.
3061 --- 1.0pl1 1995/12/5
3063 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3065 Bug in Explain DatabaseInfo module fixed.
3067 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3071 The shift to v1.0 signals that we now consider the *core* functionality
3072 of YAZ reasonably stable (the core being more or less equivalent to
3073 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3074 tested (Explain not at all - though that will happen soonish).
3076 Minor changes to code to support Windows port.
3078 Various minor changes after we're getting to use GRS-1 & co. more.
3080 Added Espec-1 format.
3082 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3083 of the protocol and it cannot be selected when encoding (maps into 'string'
3084 when decoding). Needed to talk to some servers.
3086 Demo client can request simple element set names.
3088 Added Diagnostic Format encoders/decoders.
3090 Added simple Close handling to frontend server (no hooks for resource
3091 reporting yet), and demonstration client.
3093 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3095 --- 1.0b3 1995/08/24
3097 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3098 handled incorrectly when records were requested in the searchResponse. This
3099 will only affect you if you use the frontend-server.
3101 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3102 Test-client will ask for and print GRS1. Ztest will return dummy records
3105 Added Explain encoders/decoders to the service-level API. Untested.
3107 Added Extended Services: Item Order encoders and decoders to the Service-
3108 level API. Untested. We could use a recent copy of the pertinent bits
3109 of the ILL protocol to add those bits.
3111 Added diagnostic format 1 encoders/decoders to the service-level API.
3114 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3115 odr_cons.c, which causes a more correct output.
3117 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3118 was always set to 0 when no records were requested in the searchRequest.
3120 * Added better external-handling. This shouldn't harm old code that
3121 *encodes* externals. It can break code that looks for a
3122 'single-ASN1-type' representation, since those types that are known
3123 are now decoded immediately. Look at the SUTRS sample code in
3124 seshigh.c and client.c. Documentation updated.
3126 Handling of structured records in bend_fetchresponse. Length -1 marks
3127 structured record, type is deduced from format field.
3129 --- 1.0b2 1995/06/27
3130 Fairly quick maintenance release to add SUTRS support.
3132 Fixed handling of SUTRS records in the demonstration client.
3134 * Added format field to the bend_fetchrequest and bend_fetchresponce
3135 structures of the backend API (frontend server). When the record is
3136 returned, the value of the format field is mapped to an OID. The
3137 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3138 of the record. The special value VAL_NONE in the bend_request means
3139 that no specific format was requested by the client. Documentation
3140 updated accordingly. Test server (ztest) will return a fixed dummy
3141 SUTRS record if your client requests SUTRS.
3143 Documentation updated accordingly.
3145 You can now set external libraries and RANLIB support in the top-level
3149 First public release.
