1 cql_sortby_to_sortkeys: honor sort prefix.
3 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
4 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
5 The rpn2cql family of functions now always returns quoted CQL terms.
7 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
11 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
12 sequence is treated as one. For example, &&a=b&&&c& is identical to
17 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
18 APDUs for a connection to a WRBUF.
22 Fix cql_sortby_to_sortkeys. Completely broken before.
24 Make CCL's @truncation work again.
28 New ZOOM connection setting: tproxy. It's like proxy, but does not
29 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
30 to set resolved address + port for a connection outside ZOOM itself.
32 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
36 Fix uninitialized variable in Solr spell support (could cause SEGV
37 for SRU response decoding).
39 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
40 back-end's addinfo through into the ZOOM response addinfo.
42 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
43 they are separated by a colon and a space rather than simply
48 Add support for Solr spell-checking/suggestions through ZOOM.
49 If a Solr target has been configured correctly for spelling-checking
50 and suggestions, these will now be returned on the ResultSet option
51 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
55 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
56 with a flag whether to substitute escape sequences or not.
60 Fix nmem_strsplit_escape to substitute escape char properly.
62 New option for zoomsh -e , which makes it abort on first error and
63 return process exit code to indicate success/failure.
65 YAZ options utility supports special option -- which makes all it treat
66 all following arguments as non-options.
70 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
71 searched if absolute filename is given.
73 Fix conv_xslt() error-reporting when stylesheet is not found.
74 (The value of fullpath is meaningless in this situation.)
78 Fix problem in CQL sort node creation: un-initialized memory.
80 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
81 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
82 CQL sortby depending on whether Type-1 or CQL is actually sent to the
85 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
86 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
88 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
89 will make it possible to use both single-character mask (#) and wildcard (?)
90 in CCL . Throw diagnostic for left truncation because that is not supported
95 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
96 cases using escapes (\-sequences) and masking.
98 PQF parse fix: A trailing backslash followed by end-of-string (\0)
99 would result in a read one byte beyond string.
101 rpn2ccl may use Z39.50 masking for terms (t=z).
103 ICU check fix. Don't include library -lCrun on Solaris, unless present.
105 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
106 not --cppflags (which seeems like an error in icu-config).
108 --- 4.2.12 2011/08/27 RPM package only
110 cql2ccl: fix conversion of terms: operator characters were not
113 --- 4.2.11 2011/08/25 RPM package only
115 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
116 CCL parser will map both # and ? to their regular expression
117 quivalents (. and .*).
119 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
120 of reserved CQL characters.
122 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
123 is, so that they are passed through.
125 --- 4.2.10 2011/08/24
127 ZOOM SRU mode: more aggressive re-connect.
129 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
130 made available as a utility function, declared in <yaz/logrpn.h>
132 rpn2cql_structure() supports proximity nodes (except that the Type-1
133 proximity node's "exclusion" binary is ignored, as there is no way to
134 express that in CQL). Fixes bug #4564.
138 Fix SEGV that could occur if set command of zoomsh was given without
139 value (2nd argument).
141 Fix SEGV that could occur if unsupported transport was given for
142 COMSTACK - say https (when SSL was unavailable).
144 Build yaz-url on Windows too.
148 New utility to get web content. Header is url.h. A command line tool
149 yaz-url is part of the distribution and packages.
151 Fixes for SSL COMSTACK (when gnutls is in use).
153 New functions yaz_base64{encode,decode}. Header is base64.h.
157 ZOOM C includes HTTP response buffer as additional info if it fails
158 to decode the SRU response.
160 Make wrbuf_json_puts available.
164 zoom: throw diagnostic for invalid value for option "sru". Before a
165 bad SRU request was sent.
167 Adding new utility wrbuf_vp_puts.
169 Add cclxmlconfig.obj to win/makefile. It was missing completely.
173 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
174 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
175 redirect was used at the same time.
177 MARC line mode decoding: be less picky about length given - first
178 5 digits of header that is.
180 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
182 Changes to decoding of SRU records: a record with recordPacking=xml is
183 modified with a new root element <yaz_record> if the recordData contains
184 multiple children elements. This is to make the record XML parseable
187 RPN to SOLR conversion: encode special characters.
189 Generic Frontend Server: fix uinitialized member, stepSize.
193 Fix a bug in SRU decoding of records.. The database records stored
194 had un-initialized memory, but it would only be seen with yaz_record_render
195 and type_spec="ext" .
197 Fix a bug in ccl_qual_dup introduced in 4.2.3.
201 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
205 Add new utilities to convert from CQL to CCL . These utilities have
206 prefix cql_to_ccl defined in cql.h.
208 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
209 lead to memory heap corruptions when ICU utilities were in use.
213 Make compilation work without Libxml2.
215 yaz-client: remove redundant blanks in display of searchResult-1 term
220 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
221 resulting CQL node (tree) in a new node CQL_NODE_SORT.
223 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
224 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
225 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
226 Note that the CQL sortby spec is only converted when the GFS is already
227 converting from CQL to RPN (cql2rpn element).
229 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
230 specify whether to collapse delimitors or not. The existing nmem_strsplit
231 do collapse (collapse parameter = 1).
233 Windows installer: For NSIS, set InstallDir depending on x86/x64.
235 Rename internal func yaz_use_attribute_create. While non-static, this
236 function is not declared in a public header.
240 Add -lCrun when linking with ICU on Solaris.
242 More quicks character set conversions for OPAC records.
246 fix problem with record_render: records were converted (character set
247 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
251 SRU: add methods for handling DADS SRU-proxy facets.
253 Separate OPAC record character set for ZOOM_record. yaz_record_render
254 allows a character set given as charset=from/opacfrom,to where 'from' is
255 the character set of a bibliographic record, 'opacfrom' is character set
256 of OPAC record and 'to' is the target character set.
260 yaz-client: show may XML format records. Command show followed by 'format'
261 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
264 src/stemmer.c: Avoid using unnamed union. It is not supported by some
267 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
270 Update yaz.spec to operate on both SLES11 / Centos 5.5.
272 RPM: Release includes 'indexdata' name. Use indexdata in release name so
273 this package can be distinguished from other vendors.
275 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
276 as determined by configure
278 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
280 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
281 returns no error and no record, the present request is considered
282 partial (only a subset of the records could be returned by backend), and
283 so it is appropriate to set Present Status to partial-4.
287 Move yaz-config man pages to section 1.
289 More documentation about SOLR.
291 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
292 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
293 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
294 peers on some Linux systems. However, in general that does not work
295 so YAZ can not rely on that to work. Debian changed behavior in this
296 respect from Debian lenny to Debian squeeze (still testing as of Oct
298 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
300 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
304 Fix yaz-config output: echo_source not set correctly by configure.
308 SOLR WebService support for yaz-client and ZOOM.
310 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
312 --- 4.0.12 2010/08/17
314 Z39.50 facet support. Facet specifications are passed for search in
315 other-information with ASN.1 as defined in facet.asn and OID
316 .10.1000.81.5 . Facets are expressed as an Attribute list as known
317 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
318 3 is limit (number of entries to get in response). yaz-ztest returns
319 dummy facets if a client asks for them.
321 --- 4.0.11 2010/07/09
323 CCL fixes: bug 2895 and bug 3539.
325 GR1-display: add comma in display - was removed by mistake in
328 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
330 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
332 --- 4.0.10 2010/06/18
334 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
335 result set from a connection. The result set will be on its own
336 thereafter; no operations on it will perform retrievals from a target.
337 Only cached copies are returned.
339 ZOOM C:fix case for HTTP servers responding with Connection:close.
340 Ensure that if there is a current task it is resumed (like fetching
341 more records in a result set) . Bug #3484.
343 PQF parser: use odr_atoi for Odr_int (not atoi)
345 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
346 values that contain any non-digits are treated as string attributes
347 (previously decoding only checked for leading character ([0-9]). PQF
348 encoding: attribute string values are not surrounded by double-quotes.
352 New utility for managing threads - thread_create.h.
354 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
355 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
356 but YAZ' implementation do.
358 Fixes for yaz_cond-functions on Windows 7.
360 DLL export more symbols.
362 zoomsh: show record do NOT render opac.
364 Remove *.la files from Debian and RPM packages.
368 Debian package libyaz-dev depends on libgnutls-dev again (was
369 removed in YAZ 4.0.6, but due to Libtool it is still needed
370 even though yaz-config do not list libgnutls libs).
372 ZOOM: Use only one WRBUF for returning string results for
373 ZOOM_resultset. Reduces memory usage for ZOOM in general.
375 ZOOM: ZOOM_connection do not use a shared pointer to
376 ZOOM_resultset after ZOOM_resultset is destructed by
377 user. Reverts to YAZ 4.0.4 behavior.
381 record-conv: fix problem with at least one XSL conversion -
382 due to probably incorrect usage of XML XSL documents.
386 Fix yaz-config for static mode and the use of SSL (gnutls).
390 Forward decl timeval struct in mutex.h and gettimeofday.h.
392 yaz-config: fix 'static' mode linking.
396 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
397 are wrappers for pthreads or Windows. For Windows these are put in
398 a separate DLL: yaz_cond4.
400 libyaz.la (whole source) is compiled with thread. If thread support
401 is enabled enabled, all source of YAZ is compiled with treading support.
402 This allows core utilities such as yaz_log to use thread facilities.
403 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
404 thread utilities. This commit moves mutex utilities (mutex.c) from
405 libyaz_server.la to libyaz.la.
407 yaz-json-parse displays leading text until error.
411 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
412 patch from Giannis Kosmas.
414 SRU: no longer URL encode SRU database. The URL for an SRU server is
415 a URL and such is alreeady encoded - at least when given with leading
416 http:// or https://. This reverts behavior to YAZ 3.0.50.
418 Support for new MARC XML notation TurboMARC which like MARCXML is a
419 complete representation of MARC/ISO2709.. This one, however, is more
420 compact and allows for faster processing with XSLT. TurboMARC can be
421 used in the marcdisp.h API, from the yaz-marcdump utility and from
424 yaz-ztest can be configured - via the database - to perform certain
425 delays when it performs operations search, present and single record
426 fetch. This allows testers to make yaz-ztest act as a real or even slow
427 Z39.50 server. Refer to the yaz-ztest man pages for details.
431 wrbuf_destroy allows NULL WRBUF passed to it.
433 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
435 Add ZOOM_connection_close.
437 No fixed size buffers for ZOOM shell - bug #3257.
439 tstodr: make it work on s390 platform.
441 New icu iterator-functions. The new icu_iter-functions makes it possible
442 to use ICU chains from many threads.
444 yaz-client: better syntax check for show command.
448 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
451 New simple local-file XML include facility which allows file glob-patterns.
452 Refer to yaz/xml_include.h.
454 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
457 ZOOM_record_get supports new parameter "format" which makes it format XML
460 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
461 JSONText in ECMA-262) is JSONValue, not JSONObject.
465 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
466 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
468 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
469 POSIX/Unix builds .so with major version 4.
471 Remove old LOG_-defines from log.h. They have been obsolete and
472 undefined by default for the last 5 years.
474 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
476 GFS: Remove socket (int *fd) from search_rr handler. The socket
477 descriptor ptr is a facility that allowed a search handler to supply
478 a socket which would serve as a callback - when search was complete.
479 This facility has now been in use for years.
481 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
482 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
483 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
484 returns 'const char *' rather than 'char *. The returned string is
485 read-only and should not be modified by applications. COMSTACK cs_close is
486 now a void function - it no longer returns int. No applications check for
487 the value and the implementations has always returned 0.
489 ZOOM: use size_t for scan hit counts and str size. Functions
490 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
491 occ (hit count) and len (string length) are now of type size_t pointer
492 rather than int pointer. This is to be able to represent large hit counts
493 and to also just to use the proper type for string length (strlen result).
495 New JSON parser. Refer to include/yaz/json.h .
497 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
498 Used to be int in some cases. Many wrbuf_-functions used to return an int
499 indicating some length.. These return values were never used. And so they
502 ODR: odr_malloc, odr_total now takes size_t for size.
504 clone_z_type: fix leak; occurred for encoding failures.
506 --- 3.0.52 2009/12/03
508 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
509 bug was introduced in 3.0.51.
511 --- 3.0.51 2009/12/02
513 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
515 tcpip comstack: fix leak for getaddrinfo.
517 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
518 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
519 Decoding of SRU "path" database is performed by private function
520 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
521 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
523 yaz-client: honor base command for SRU. Change when database setting
524 is applied for SRU and ensure it is kept when a connection is reset.
525 Change also the way errors are displayed or SRU (decoding of packages).
527 --- 3.0.50 2009/11/02
529 Add support for extra request / response data for SRU codecs and GFS.
530 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
531 for extra data response buffer and length. For the GFS, both request
532 and response data (XML) is carried in extra_args and extra_response_data
533 for the search handler. Patch by Ko van der Sloot.
535 ZOOM: For queries that cannot be converted to the specified rpnCharset,
536 ZOOM now returns a diagnostic on the client-side ('invalid query' /
537 10010). This fixes bug #2113.
539 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
540 cmdfile included a 'quit' command that would result in a memory violation.
542 --- 3.0.49 2009/10/01
544 Make a number of functions defined in xmlquery.c static. These have
545 never been declared in a public header file (yaz/xmlquery.h) and was
546 made public by mistake.
548 Improve speed of character conversions (iconv utilities). This makes
549 conversions from MARC-8 faster.
551 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
552 unless type desired is "raw". This will prevent type "xml" from
553 returning ISO2709 .. Which obviously can not be XML parsed.
555 Fix memory leak in ZOOM that would occur if option apdulog was used
556 on a re-used connection.
558 Frontend server logs HTTP requests.
560 Frontend server now sends Z39.50 close when it times out (sesssion has
561 been idle for too long). Versions 2.0.30 and earlier also sent close.
562 But due to a mistake this was disabled in all versions after that, i.e.
563 the server would just close the socket immediately.
565 yaz-client emits a better message when receiving an unrecognised
566 userInformationField.
568 Skip zero-length subfields when decoding ISO2709. This rare case happens
569 if a record has two FS characters in a sequence. Without this patch
570 there would be a reference beyond char array in using_code_len fragments
573 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
575 --- 3.0.48 2009/08/28
577 The show command offered by the zoomsh command now takes a 3d optional
578 parameter type which is what is passed to ZOOM_record. If the type
579 argument is omitted, "render" is used.
581 RPN to CQL conv may use USE string attributes (bug #2978).
583 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
585 --- 3.0.47 2009/07/08
587 Function yaz_xml2query allows a diagnostic element in the PQF XML
588 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
589 code and additional info respectively.
591 The BER BOOLEAN is now the integral type Odr_bool which still happens
592 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
593 typedef'd to Odr_int. This is still an integral 'int', but it may be
594 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
595 ASN-1 compiler as well as programs has been updated to use the new types.
597 --- 3.0.46 2009/06/08
599 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
600 only the bibliographic record was rendered. For type=opac, an OPAC
601 record is only returned if it is present.
603 iconv: small fix for encoding of advancegreek.
605 yaz-client: avoid double display of SRU/SRW records (bug #2798).
607 yaz-client: option auto_reconnect=on really reconnects.
609 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
611 server: avoid null ptr ref for for yaz_poll errors.
613 build: fix RPM build for RHEL 5.3.
615 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
617 --- 3.0.45 2009/03/31
619 Fixed bug #2709: TCP connect returns Invalid argument.
621 Fixed compilation for mingw.
623 Honor charset for raw records (ZOOM_record_get).
625 Fixed use of errno for threaded mode that was seen on Solaris 10.
627 Fixed argument passing with blanks in value for Windows Service.
629 Disable YAZ' own log rotate by default (no 1 GB limit).
630 The variable l_max_size which specifies the log file limit is set to 0
631 (DISABLED): This is due to the fact that YAZ is most often deployed using
632 logrotate. Also YAZ can not perform log rotate because of unsufficient
633 permissions (setuid).
635 --- 3.0.44 2009/02/17
637 List supported encodings in man page for yaz-iconv.
639 Fixed missing SSL libs for --libs output
641 Re-established OID record syntax application-xml. Nobody should use it
642 but we don't want to change soname because of this symbol being absent.
644 --- 3.0.42 2009/02/02
646 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
648 Added member named_result_sets for init handler struct for the GFS. This
649 allows a server to disable named result sets.
651 Removed OID record syntax application-xml.
653 Added support for rule-based transliterator for ICU wrapper of YAZ.
655 Fixed bug #1902: yaz-icu XML output.
657 Make YAZ checks Emacs friendly.
659 BITSTRING value shows value. Bug #2346.
661 ISO2709 decoding: skip control characters from indicator data.
663 Omit sort key by default in yaz-icu's output.
665 Allow combined single char options (again) for YAZ' options function.
667 Utility yaz-marcdump got option to display YAZ version (-V).
669 Allow YAZ to use ICU 3.4.
671 Added new ICU test case which illustrates removal of diacritics.
673 --- 3.0.41 2008/12/29
675 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
677 --- 3.0.40 2008/12/29
679 For configure, using option --without-xml2 also disables Libxslt/Libexslt
682 Fixed bug #2352: yaz-marcdump crashes for certain record.
684 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
686 Added support for Danmarc2 to UTF-8 conversion.
688 Added support for ISO5426 to UTF-8 conversion.
690 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
691 implementation version.
693 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
695 --- 3.0.38 2008/11/10
697 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
698 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
700 ZOOM C now interprets databaseName option for ZOOM connection as path
703 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
705 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
707 Dummy Libxml2 types no longer defined in headers of YAZ'.
709 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
712 --- 3.0.36 2008/09/26
714 Various ODR chapter fixes.
716 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
718 Added missing source for Windows compilation, mutex.c.
720 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
722 For SRU connections in ZOOM all records up to "count" are now fetched.
724 Fixed crash in generic frontend server (and yaz-ztest) which occurred
725 in Windows due to bad error handling for Libxml2.
727 Added facility for sending arbitrary records (ASN.1 any) using
728 ZOOM C's Extended service update. Patch by Sam Reynolds.
730 New options for ZOOM C's connection, logapdu which makes ZOOM log
733 --- 3.0.34 2008/06/18
735 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
737 --- 3.0.32 2008/06/12
739 Fixed memory violation that could occur when decoding UTF-8. This bug
740 was only present in 3.0.30 of YAZ.
742 --- 3.0.30 2008/06/06
744 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
745 GNU TLS is used by default (if found).
747 yaz-ztest returns OPAC records if a client asks for OPAC.
749 Improved speed of MARC-8 encoding.
751 Added support for lossy and loss-less MARC-8 encoding.
753 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
755 Added new Windows Service wrapper (sc).
757 yaz-client's itemorder command may now send a file.
759 Fixed yaz-marcdump to allow the use of NS prefix for record element.
761 Added new function yaz_log_xml_errors.
763 Allow (but warn) unknown XML attributes in MARCXML parsing.
765 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
767 The UTF-8 to MARC-8 conversion now uses a different set of characters
768 for Greek symbols. Bug #2120.
770 --- 3.0.26 2008/02/21
772 Added yaz_daemon (daemon.h).
774 Fixed bug #2068: pkg-config trouble
776 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
778 --- 3.0.24 2008/01/28
780 Document --with-xml2 option.
782 Added OPAC XML XSD (etc/opacxml.xsd).
784 Allow glob mask for name attribute in retrieval element for the
785 generic frontend server's retrieval facility.
787 Changed yaz_poll_poll to return yaz_poll_except for all returned events
788 except POLLIN/POLLOUT.
790 Fixed error handling in cs_listen. Bug #2037.
792 --- 3.0.22 2008/01/20
794 Fixed version in yaz/yaz-version.h.
796 Fixed bug #2027: Crash when closing connection.
798 Changed configure so that ICU support is only enabled if only ICU
799 and Libxml2 is available (because the ICU chain is XML based).
801 --- 3.0.20 2008/01/15
803 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
804 is built. Only this DLL depends on the ICU runtime.
806 yaz-ziffy is no longer part of YAZ. It is distributed separately by
807 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
809 Changed license of CCL module to 'Revised BSD'. After consultation with
810 remaining members of the original EUROPAGATE consortium, we are re-issuing
811 the CCL module without a separate license. The software was developed by
812 Index Data as part of a research project. The special license was included
813 to help feed usage information back to the project consortium to support
814 project evaluation. At this time, the project consortium has long-since
815 disbanded, and the majority of the original principals have retired. At the
816 same time, we have significantly modified the software during the following
817 years, to the point where very practically no original code remains. To
818 simplify re-use of the software, we have contacted those members of the
819 consortium who could be reached, and agreed to re-issue the module as a
820 proper part of the YAZ package.
822 Tcl scripts uses /usr/bin/tclsh as preferred shell.
824 CQL closer to being version 1.2 compliant. CQL also allows free-form
825 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
828 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
829 bug could make Extended services handling crash in the ZOOM layer. This
830 bug was only present in YAZ 3.0.18.
832 --- 3.0.18 2007/12/19
834 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
837 yaz-marcdump reads and writes collection wrapped records.
839 Handle OPAC for record conversion module.
841 Fixes for ICU wrapper.
843 Allow ICU libs to be controlled with --with-icu .
845 --- 3.0.16 2007/11/12
847 Added yaz_poll which is a wrapper for select/poll. When poll is available
848 and non-buggy, it is used, by yaz_poll . This allows more than 1024
849 sockets to be in use.
851 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
852 functionality through an XML based configuration (ICU chain). This system
853 is useful for search facilities such as Pazpar2 and Zebra that needs to
854 perform tokenization of indexed material. The ICU code in a separate
855 library libyaz3_icu.a.
857 Added HTTP tunnel facility for COMSTACK, bug #1752.
858 This is a facility that allows a Web proxy, such as squid, to tunnel
859 Z39.50 traffic. This facility is "transparent" to must applications
860 using YAZ. It's enabled by using pseudo transport connect: followed by
861 the proxy address, followed by command, then follwed by he regular
862 "virtual" addresss. For example,
863 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
865 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
867 --- 3.0.14 2007/09/21
869 Fixed bad memory reference in ZOOM_record - cuased by member not being
870 initialized. This was a problem only in YAZ 3.0.12.
872 Fixed bug in conversion from MARC to XML: Non-XML characters in control
873 fields were not removed.
875 Changed the way C code is generated from codetables.xml. Made a MARC-8
876 conversion trie for each characterSet section rather than codeTable.
877 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
878 of codetables.xml from Larry Dixson, LOC. Bug #1464.
880 --- 3.0.12 2007/09/12
882 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
883 from ZOOM_record_error).
885 ZOOM C function ZOOM_record_get returns record schema for type="schema".
887 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
889 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
891 Better SRW-to-Bib-1 diagnostic mapping.
893 ZOOM C and yaz-client announces SRU version 1.2 by default.
895 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
898 Fixed in yaz_sru_decode to allow other version than 1.1.
900 --- 3.0.10 2007/08/22
902 Added support for SRU scan for ZOOM.
904 Added support for the use of the older versions or Extended Service
905 Update in ZOOM. To faciliate this, an option "updateVersion" may be
906 set to the version , 1=first, 2=second, 3=third. The third version is
907 what ZOOM C has used so far. And that, obviously, is the default.
909 Added support for CCL queries in Z39.50 queries sent to the GFS (and
910 therefore in Zebra and in SimpleServer-based applications). The new
911 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
912 qualifier file used to transform incoming CCL queries into Type-1 RPN,
913 which is passed into the back-end search callback function.
915 Added support for HTTP Basic authentication in clients: the SRU/W
916 codec encodes the username/password elements of the PDU structure
917 appropriately, and these may be set using the "user" and "password"
918 options in ZOOM-C applications (the same options that are used for
919 Z39.50 authentication).
923 Fixed bug #1208: SSL appears to be broken in ZOOM.
925 Fixed bug #1206: Libxml2 include path weirdness.
927 Added oid_name_to_dotstring.
929 Allow elementSetName to be specified for ZOOM C record update.
931 Allow waitAction to be specified for ZOOM C based for Extended Services.
933 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
934 syntax OID. Bug introduced in YAZ 3 series.
936 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
940 Fixed bug #1157: yaz-client does not read .yazclientrc from current
941 directory. yaz-client now reads commands from file given by option -f
942 if specified; then tries to read .yazclientrc in current directory.
943 Failing that, it reads .yazclientrc from user's home directory.
945 Added support for correlationInfo Note and ID for Record Update via
948 Added yaz-client command querycharset which specifies character set for
949 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
950 (termListAndStartPoint).
952 Charset ISO5428:1984 is an alias for ISO5428-1984.
954 Implemented a way to perform scan in a result set using Z39.50. This
955 is achieved by attaching the result set name in the characterInfo
956 (type InternationalString) of OtherInformation in the Scan Request PDU.
957 The result set is identified in the otherinformation by the new OID:
958 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
959 This allows for scan in result set and faceted search . Zebra did some
960 of this in the APT term using attribute type 8 and value being result
961 set. Using the OtherInformation approach for this is cleaner and easier
962 to work with in proxies and the like. This facility can be used in
963 yaz-client using new command setscan which takes a result set as first
964 argument, start position (APT) as second.
966 Changed decoding of SRU XML packed records to deal with servers that
967 have recordData with XML data with multiple root nodes. Also make
968 comparison for recordPacking case insensitive. Again, one server
969 returns "XML" where others return "xml".
971 For SRU responses allow Content-Type application/xml as well as text/xml.
975 Fixed bug in character set conversion of BER strings. Bug introduced
980 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
982 For OID class, use oid_class consistently.
984 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
987 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
988 character set for bibliographic information interchange". By Giannis Kosmas.
990 Added documentation on new OID API.
994 Changes to generic frontend server interface: added new member
995 'query_charset' for bend_initrequest structure. A backend init handler
996 should set this member to its native character set for query terms.
997 When defined, the frontend server logic will announce this character set
998 to a client if the negotiationModel bit is set by the client. All server
999 implementors are encouraged to specify this. If a backend server does not
1000 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1002 Added CCL utility to remove terms (stop words) from resulting RPN
1003 tree. This is handled by functions with prefix ccl_stop_words_ .
1005 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1006 terms in RPN queries.
1008 Clean-up the CCL API. Moved some internal structures from ccl.h to
1009 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1010 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1011 This is replaced by ccl_parser_find_str which takes a string instead.
1013 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1014 libyaz.la is the core of YAZ except the generic frontend server and
1015 does not depend on POSIX threads anymore. libyaz_server.la is the
1016 generic frontend server facilities and uses POSIX thread functionality
1017 if available. The libyaz.la no longer depends on POSIX threads because
1018 the number of global structures is limited. NMEM no longer re-uses blocks
1019 between threads ; it simply free's memory immediately but allocates in
1020 "large" chunks as usual. We don't expect any performance penalties
1021 because of this. The yaz_log system is still using a global log_level so
1022 caution must be taken when modifying it with yaz_log_init_.. +
1023 yaz_log_mask_str. This, however, should not cause any trouble because
1024 these functions are called during initialization of application code
1025 anyway. `yaz-config --libs server` returns libs for server applications;
1026 `yaz-config --libs` returns libs for non-server applications.
1028 New OID database - with public definitions in oid_db.h. Removed old OID
1029 database including the head oid.h and definitions such as enum oid_value
1030 and struct oident. The new OID database uses the same string names as
1031 before but the 'protocol' is gone. There are now only two representations
1032 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1033 converts from string to OID; functions with prefix yaz_oid_to_string
1034 converts the other way.
1036 Change to emit_term() in CQL-to-PQF query translation: when a term has
1037 the /regexp relation modifier, do not process it for leading and
1038 trailing "^" and "*", which have quite different meanings in regular
1041 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1042 write handlers no longer carries a 'last' parameter. This will make
1043 yaz_iconv flush "less" characters. A flush is performed by call to
1044 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1046 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1047 removed, because function yaz_query_to_wrbuf does the same.
1049 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1050 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1052 Deprecated MARC utility functions removed.
1054 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1057 Branch split: YAZ_2_1_55_branch
1059 --- 2.1.54 2007/03/16
1061 Fix to ZOOM-C so that transparent reconnection is properly handled on
1062 connections that are in asynchronous mode.
1064 Fixed compilation on OpenBSD 4.0.
1066 Large strings in GRS-1 records are now properly displayed in yaz-client.
1068 Added character conversion support for "advancegreek"; based on patch from
1071 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1072 sequence is met. Before the error was not set so it would be unknown.
1074 Adjust yaz-marcdump MARC reader so that it skips until record separator
1077 --- 2.1.52 2007/03/07
1079 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1080 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1081 fd_set structure used as a bitmask for the FDs to be selected on.
1083 Using ACX_PTHREAD macro to check for POSIX threads.
1085 Fixed have-vsnprintf check.
1087 --- 2.1.50 2007/02/23
1089 Fixes for configure on BSD. Bug #900.
1091 Added snprintf/vsnprintf wrappers for systems that don't have
1092 limits (heavens forbid).
1094 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1095 created before all previous tasks were completed and removed from the
1096 task queue, the new task could be removed by a mistake.
1098 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1100 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1102 Fixed bug #832: Problem with MARC/charset in yaz-client.
1104 Fixed bug #668: save command line history for yaz-client.
1106 Fixed bug #830: pkg-config support.
1108 --- 2.1.48 2007/01/23
1110 Extended ZOOM result set options with two options that may be read by
1111 a client: resultSetStatus and presentStatus with values as specified for
1113 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1115 Fixed bug #827: Using SSL fails on Debian etch.
1117 Fixed bug #826: Weird looking chars for set of MARC records.
1119 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1120 that is treated as an ItemOrder with itemRequest being an XML document
1121 external. The value of "doc" is the content.
1123 Extended the GFS search facility. New member of bend_search_rr
1124 'estimated_hit_count' signals that hits is known to be an estmate
1125 (higher or lower than real hit count). New member 'partial_resultset'
1126 signals that the search was partial (hit count is lower or equal than
1127 real hit count). For Z39.50, the information is stored in resultSetStatus
1128 member of SearchResponse APDU. For SRU, the information is signalled
1129 via SRU diagnostic 59: "Result set created with valid partial results
1132 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1134 --- 2.1.46 2007/01/13
1136 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1138 Added ZOOM_connection_peek_event.
1140 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1141 the following new functions:
1142 ZOOM_event_nonblock, ZOOM_connection_process,
1143 ZOOM_connection_get_{socket,mask,timeout},
1144 ZOOM_connection_fire_event_{timeout,socket}.
1145 The existing blocking event handler, ZOOM_event, is a wrapper for the
1146 + blocking ZOOM_event_sys_{poll,select}.
1148 Implemented function ccl_xml_config which parses XML version of CCL
1149 configuration (bug #798).
1151 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1153 Added timings utility (yaz/timing.h)
1155 --- 2.1.44 2007/01/03
1157 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1160 Fixed bug #779: Rotation of apdu.log fails.
1162 Fixed for character set conversions:
1163 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1164 Honor G1 set in MARC-8 decoding.
1166 --- 2.1.42 2006/12/17
1168 Fixed bug #775: char conversion does not handle Alternative UTF-8
1171 Implemented function yaz_marc_read_line which parses MARC line format
1172 records. There is a wealth of formats out there. So far, this function
1173 reads line records produced by yaz_marc_write_line.
1175 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1176 more generic and easier to remember(!) options: -i format and -o format
1177 which specifies input format and output format respectively - where
1178 format is one of "marc", "marcxml", "line", "marcxchange".
1180 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1181 does not print anything except warnings for records.
1183 For yaz-marcdump, added support for MARC split into files (-s) with a given
1186 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1187 spec, at http://www.loc.gov/standards/sru/record-update/
1188 This has changed the binary layout of the following structs:
1189 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1190 bend_update_rr . Patch by Ko van der Sloot.
1192 Added GFS utility function bend_assoc_is_alive which returns 1 if
1193 association is still alive (client is connected); 0 otherwise (client
1194 closed connection). This allows busy servers to stop working for
1197 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1198 been a separate piece of software. This version of ziffy has been modified
1199 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1201 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1203 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1204 Client code may now interrogate options such as "init_opt_sort" to
1205 find out whether the server claims to support various options.
1207 --- 2.1.40 2006/11/27
1209 Added utilities yaz_{set,get}_esn to set/get element set name from
1212 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1213 of YAZ and has been so since YAZ 2.1.10.
1215 Implemented ZOOM_record_error which returns error information for
1216 record (surrogate diagnostic).
1218 --- 2.1.38 2006/10/31
1220 Updates for SRU Update by Ko van der Sloot:
1221 1. Changed name from "operation" to "action"
1222 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1223 versions in the code, marked as 'backward compatible'.
1224 3. Added diagnostics for SRU Update.
1226 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1228 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1230 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1232 For GFS, fixed problem with SRU diagnostic 'First record position out of
1233 range' being issued for 0 hits.
1235 zoomtst10 part of Windows Build.
1237 --- 2.1.36 2006/10/13
1239 Implemented yaz_filepath_comp which splits a path into file path
1240 components (required by Zebra 2.0.3+).
1242 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1243 BSD inspired license until now so this should not have any real impact on
1244 anybody. See http://www.opensource.org/licenses/bsd-license.php
1246 Fixed bug #687: Missing log lines.
1248 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1251 Fixed bug #689: SRU diagnostics to be added.
1253 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1254 whether a connection is idle (no more work do do).
1256 --- 2.1.34 2006/10/04
1258 Change type of optval from long to int for invocation of setsockopt with
1259 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1261 Added support for specifying the max log file size for the Generic
1262 Frontend Server. The size is given with option -r.
1264 --- 2.1.32 2006/09/21
1266 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1268 --- 2.1.30 2006/09/17
1270 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1273 Fixed bug in Generic Frontend Server that could cause a server to stop
1274 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1276 For the generic frontend server, the maximum record size is used as maximum
1277 size of incoming packages (SRU + Z39.50). The value until was previously
1278 only used in Z39.50 Init negotiation and, later, in a session controlled
1279 sizes of records returned. This is controlled using -k option. It can be
1280 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1282 --- 2.1.28 2006/09/04
1284 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1287 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1289 New option for yaz-marcdump -lpos=value which allows setting a portion
1290 of MARC header to a certain value.
1292 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1294 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1295 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1297 --- 2.1.26 2006/08/15
1299 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1302 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1304 --- 2.1.24 2006/08/08
1306 Fixed MARC ISO2709 encoding routines to deal with character set
1309 Minor changes to GFS logging. Database included in search request log
1312 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1313 cached/multiple records.
1315 Shared libraries are built by default on Unix+configure.
1317 Changed cql2pqf transformation to use a different evaluation order. The
1318 new order is: always, relation, structure, position, truncation, index
1319 and relationModifier. Old order was: always, relation, relationModifier,
1320 structure, index, position, truncation. Note that the the latter ones
1321 override former ones for identical attributes.. The new scheme means that
1322 it is possible to override any existing attribute with a relationModifier.
1323 And also that it is possible to override everything for the index rule
1324 (except the ones listed in relationModifier). No order is perfect but this
1325 one, we believe, covers more real cases.. The "always" should have been
1326 called "default", since the attributes there can be overridden with all
1329 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1330 compilation phase, but also for yaz-config --cflags output. This allows
1331 us to have public headers with Libxml2 stuff in them . It should also,
1332 eventually, make Libxml2 checks redundant in packages using YAZ, such
1335 --- 2.1.22 2006/06/15
1337 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1338 stored in uri, message and details.. Previously diagnostics were stored
1339 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1340 compatibility.. but he's probably the only one affected, so.
1342 Added support for CCL, compiled on the client side, in ZOOM-C. This
1343 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1344 input; the resulting query objects can be used for for searching with
1345 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1347 YAZ' configure searches for OpenSSL by default.
1349 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1350 SL_CTX_use_certificate_file. See
1351 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1352 for more info. Thanks to Ko van der Sloot.
1354 --- 2.1.20 2006/06/02
1356 Bug #600: SRU GET, POST support for yaz-client. Introduced
1357 command 'sru' which selects method SOAP/GET/POST.
1359 Allow missingValueAction to be specified for the sortspec string -
1360 function yaz_sort_spec. By default, the missing value action is null.
1361 Use ! to specify "abort". Use = followed by stringvalue to specify default
1364 Ensured that Present-handler (if defined) is called in GFS before any call to
1365 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1366 searchRetrieve requests.
1368 Documentation for YAZ is now based on the Docbook XML/XSLT using
1369 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1370 is no longer depending on jade/openjade or docbook-to-man scripts.
1371 PDF is no longer part of the distribution - but can optionally be
1372 made using DSSSL/jadetex or FOP.
1374 Added retrieval handling support in Generic Frontend Server to support
1375 conversion between MARC/XML as well as XSLTtransforms. See
1376 etc/yazgfs.xml for an example.
1378 Added Authentication support to Generic Frontend Server in SRU
1379 mode. Authentication using HTTP Basic is supported, as is the use
1380 of 'x-username' and 'x-password' parameters in the request itself.
1382 Added support for a new character set MARC8s identical to MARC8 except
1383 that it converts combined characters to single Unicode characters in the
1384 Latin-1 range (when possible).
1386 --- 2.1.18 2006/04/24
1388 ASN.1 compiler 0.4: generates brief Doxygen file header for
1389 generated .h/.c files.
1391 Utility yaz_iconv now supports conversion to MARC-8.
1393 New facilities for the MARC module. The reading - and writing of
1394 content are separate methods for the yaz_marc_t handle. The following
1395 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1396 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1397 format). Write functions have prefix yaz_marc_write_.. The existing
1398 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1399 available. Removed support for OAI-MARC and simplexml (not the
1400 simplexml from PHP5).
1402 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1403 to be returned for this connection.
1405 --- 2.1.16 2006/03/31
1407 Allow multiple languages and charsets to be specified with
1408 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1409 negcharset iso-8859-1,utf-8
1411 Translation of proximity nodes from CQL into PQF now works.
1413 Moved to automake 1.8, 1.9.
1415 Added function yaz_log_set_handler which allows a log handler to be
1416 installed. This handler will be called for all log messages. Output
1417 to file is also produced; but that can be disabled by passing NULL
1418 fname to yaz_log_init_file.
1420 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1422 For SRW (including GFS), accept application/soap+xml as content-type
1425 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1426 produces NO stylesheet reference even if a default stylesheet is specified
1429 --- 2.1.14 2006/03/14
1431 Updated Windows package to include yazd.dll + yazd.lib for the
1432 Development component.
1434 If the environment variable YAZ_LOG is set, then it is used as a
1435 string indicating the default level of logging to use if not
1436 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1437 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1438 used as before. So, for example, to omit warnings from YAZ logging,
1439 export YAZ_LOG=-warn
1441 cql_transform() now map structure and other attributes before indexes,
1442 so that index-specific structures and other attributes can override
1443 defaults. So now a combination of mapping specifications such as:
1445 index.dc.date = 1=date-modified 4=5
1446 does the right thing.
1448 cql_transform() now also respects the "always" mapping specification,
1449 which establishes an initial set of attributes to be used for all
1450 terms except where overridden by more specific attributes associated
1451 with the index, relation or modifier.
1453 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1454 which mode to use; one of "post", "get" or "soap" (SRW, default).
1456 Fixes for yaz_iconv routines: changed trie-based character set conversions
1457 to use only non-negative values for bit fields due to Sun's C compiler not
1458 supporting negative values.
1460 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1461 sequences where not read correctly. Fix by Rustam Usmanov.
1463 Updated win/makefile to use options, settings which makes things
1464 compile with VS C 2005.
1466 --- 2.1.12 2006/02/01
1468 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1470 In ZOOM socket code, use select instead of poll on MacOSX.
1472 ZOOM-C now support client-side compilation of CQL into RPN that is
1473 sent to the server, enabling CQL to be used against all Z39.50
1474 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1475 ZOOM_query object, and submit it using ZOOM_connection_search().
1476 The CQL-to-RPN translation uses a configuration file, the name of
1477 which must be specified in the Connection's "cqlfile" option.
1479 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1480 function, which takes as its start-term parameter a ZOOM_query object
1481 (which may have had either CQL or RPN set into it).
1484 --- 2.1.10 2005/11/29
1486 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1487 GFS to support this as well. Backend handler, bend_srw_update, does the
1488 update work. Code contributed by Ko van der Sloot.
1490 Allow retrieval of Search Result-1 information in ZOOM by the use of
1491 options that are attached to a result set. ZOOM documentation updated
1494 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1495 UTF-8 conversion. Patch by Raj Patel.
1497 Added option -m to GFS to control formatting of timestamps in log file.
1499 Added 'exit' as synonym for 'quit' in yaz-client
1501 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1502 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1503 for the new members. Patch by Ko van der Sloot.
1505 Added support for SRU POST. It is supported for content-type
1506 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1508 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1509 Instead make the library libyaz.la multi-threaded. Threading as a whole
1510 can still be disabled by configure option --disable-threads. Previosly,
1511 with older GLIBCs there were problems with MT libs under Apache. This
1512 has now been fixed a long time ago.
1514 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1517 CQL module modified to be case insensitive for relations/indexes/operations.
1519 Fixed bug in CQL transform code: incorrect value relationModifieder
1522 Added 'show all' command for yaz-client which retrieves all results
1525 Added new yaz-client, xmles, which takes a (private) OID and
1526 a document to be sent as an extended service request.
1528 Describe new yaz-client commands wait_response and set_auto_wait.
1530 Increase TCP/IP listener backlog from 3 (which I am guessing was
1531 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1532 that the socket will queue as many incoming connections as it's able
1533 to handle ongoing connections. In other words, it will never now
1534 refuse a connection that it would be able to handle merely because
1535 it's not got around to accepting() enough of the pending connections
1536 yet. This is the behaviour anyway under Linux, where the listen()
1537 argument is ignored; but not under BSD and on systems such as
1538 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1539 YAZ-based servers should now be uniform across operating systems in
1542 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1543 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1544 This allows yaz-marcdump to read large MARC batches (>2 GB).
1546 Modified all YAZ source files - except the source which is auto-generated
1547 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1550 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1551 corresponding to the existing *_setl() function. These allow option
1552 values containing arbitrary valuues.
1554 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1555 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1556 except that it returns an indicator of whether or not the sort
1557 criterion was accepted (0 for OK, -1 for invalid).
1559 --- 2.1.8 2005/06/07
1561 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1562 MARC output rather than returning "new" buffer.
1564 yaz-client warns about unknown init options.
1566 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1568 --- 2.1.6 2005/05/24
1570 Added support for SRW sort in Generic Frontend Server. Patch
1571 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1572 sortKeys - or NULL if none is provided.
1574 Fixed bug #307: It was impossible to specify indefinite/no timeout
1575 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1578 Added support for multiple languages and charsets to be specified in
1579 ZOOM. Each charset/language is separated by a blank. If negotiation is
1580 in effect in init-response, Option
1581 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1582 Code based on patch by Vasiliy Osadchuk.
1584 Fixed bug #306: infinite recursion that occurred when calling
1585 yaz_log_level_init as the first call (before other log level or
1588 Fixed bug in scan handling in front end server: if preferred-Position-In-
1589 Response was non-present, a NULL pointer referece was performed.
1591 --- 2.1.4 2005/04/26
1593 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1594 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1595 now defined for all those error codes. So instead of putting 109 in
1596 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1597 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1599 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1602 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1604 Program yaz-client now exits and produces an error message if multiple
1605 Z39.50 servers are specified on the command line (none or one allowed
1608 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1611 --- 2.1.2 2005/03/16
1613 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1615 Fixed bug #272: Preserve spacing for CCL terms.
1617 --- 2.1.0 2005/03/14
1619 Added support for virtual hosts and multiple backend servers for
1620 the YAZ frontend server. The configution is XML based and
1621 support specificition of CQL to RPN mappings and explain information.
1622 See section "Virtual Hosts" in the YAZ manual.
1624 Extended OPAC display utility. OPAC display utility renders
1625 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1626 to supplement yaz_marc_decode_wrbuf.
1628 Fixed a bug in MARC decoder that could caused it to crash for some
1629 invalid MARC records. More diagnostics and warnings where added in
1630 XML output (warnings, etc are stored in comments).
1632 --- 2.0.34 2005/02/08
1634 Fixes for UNIX domain sockets. Bug #261.
1636 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1638 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1639 Added yaz_marc_subfield_str which defines subfield lead string which is
1640 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1641 yaz_marc_endline_str which defines end of fields string used in
1642 YAZ_MARC_LINE format. Default string is newline.
1644 Experimental support for MarcXChange. This format can be produced
1645 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1646 http://www.bs.dk/standards/MarcXchange.xsd
1648 Added yaz-client commands scansize that sets maximum number of
1649 entries to be returned by scan.
1651 --- 2.0.32 2005/01/11
1653 Added support for SRW scan in yaz-client and Generic Frontend Server.
1655 * Added whereInList member to SRW Scan Term.
1657 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1659 Fixed NMEM system to return aligned blocks on the smallest boundaries
1660 that are suitably aligned for all possible types on the particular
1661 architecture YAZ is being built for.
1663 --- 2.0.30 2005/01/04
1665 Fixed numerious warnings that was issued with newer versions of GCC.
1667 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1668 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1671 Make YAZ Generic Frontend Server slightly faster.
1673 Enhance (and reduce) logging for Generic Frontend Server.
1675 Revert YAZ log system so that it flushes every write operation
1676 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1678 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1679 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1680 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1681 will effectively disable old definitions.
1683 --- 2.0.28 2004/11/09
1685 Added yaz_log_time_format which specifies log format using
1688 Added yaz_log_module_level which returns mask for a module. Value
1689 is non-zero mask a if module is enabled; zero if disabled.
1691 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1692 in include/yaz/cql.h.
1694 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1696 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1698 Fixed bug #172: RPM builds does not enable SSL.
1700 Doxyfile.in part of dist. Doxyfile generated by configure.
1702 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1703 are given and the corresponding component does not exist.
1705 Extend CCL documentation in YAZ reference. Describe r=r.
1707 --- 2.0.26 2004/10/01
1709 Fixed MARC->MARCXML conversion to properly deal with
1710 fields, subfields, indicators having non-ASCII characters.
1712 Fixed MARC->MARCXML conversion so that ASCII control characters
1713 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1716 Added YAZ GFS support for conversion from Z39.50 surrogate
1717 diagnostics to SRW surrogate diagnostics.
1719 Bug fix: YAZ GFS did not return schema in explainResponse.
1721 --- 2.0.25 2004/09/30
1723 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1724 now converts recordSchema to elementSetName as well as schema URI.
1726 Fixed bug in COMSTACK that prevented HTTP request packages from being
1729 --- 2.0.24 2004/09/29
1731 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1732 does not require white-space before and after the dash in a range, e.g.
1733 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1736 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1737 due to new GCC removing "redundant" code.
1739 Added yaz-client commands scanpos and scanstep that sets preferred
1740 position and step-size for scan.
1742 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1744 Added CCL utility ccl_qual_buf which parses one or more CCL
1745 spec lines in a buffer.
1747 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1748 of name and value - ignoring empty lines and comments.
1750 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1752 Added odr_get_element_path which returns current element path for an
1753 ODR handle. This utility is useful in error handling or user-defined
1756 Added ODR_PRINT utility odr_set_stream which is is a more generic
1757 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1758 to a write function and pointer to close function. The close function - if
1759 non-NULL - will be called during odr_destroy.
1761 Fixed bug in CCL parser where truncation char was not removed from
1762 right side when truncation=both was in effect.
1764 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1767 --- 2.0.23 2004/08/11
1769 Fix buffer overrun in CQL parser when dealing with proximity (%).
1771 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1772 to UTF-8/UCS conversion is now only based on codetables.xml.
1774 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1776 --- 2.0.22 2004/08/06
1778 Add support for more "commit changes" in ZOOM (uses Extended Services).
1780 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1783 Yet another small fix for configure of SSL.
1785 --- 2.0.21 2004/05/14
1787 Fix SSL libs for configure when --with-openssl=DIR is given.
1789 --- 2.0.20 2004/05/10
1791 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1793 SSL comstack now uses yaz.pem certificate file on server side
1794 by default. Certificate filename can be configured by calling
1795 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1797 Fix bug regarding multiple calls to ZOOM_connection_connect.
1799 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1801 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1802 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1804 ZOOM now allows inspection of X509 peer certificate for verification.
1805 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1807 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1808 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1809 as "modular" but it simplifies things.
1811 Added cs_get_peer_certificate to that returns peer X509 PEM.
1813 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1814 NULL if SSL is unavailable.
1816 Documentation about MARC decoding tools.
1818 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1820 --- 2.0.19 2004/03/30
1822 Rename CHANGELOG to NEWS to follow GNU style packing.
1824 Fix bug with missing initialization of member in init_diagnostics.
1825 This bug affects threaded version of GFS server.
1827 --- 2.0.18 2004/03/20
1829 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1832 Ensure zlib.dll is packed with Windows install.
1834 --- 2.0.17 2004/03/17
1836 Fix encoding of xsd:string to use text instead of CDATA.
1838 Fix endless loop in CQL parser with unbalanced ".
1840 Use a more compact way to store MARC-8 conversion tables.
1842 --- 2.0.16 2004/03/16 Debian only
1844 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1847 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1852 --- 2.0.15 2004/03/01
1854 Another fix for decoding of XML packed records.
1856 --- 2.0.14 2004/02/25
1858 Fixes for Chunked encoding. White space not ignored after length spec.
1860 Update NS and use default NS for SRW diagnostic elements.
1862 --- 2.0.13 2004/02/23
1864 Implement ZOOM_resultset_cache_reset which resets record cache.
1866 Implement ZOOM_resultset_sort which sorts a result set.
1868 Implement chunked HTTP transfer.
1870 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1872 --- 2.0.12 2004/02/16
1874 Added member 'schema' to bend_explain_rr structure so that backend
1875 can specify explain record identifier. Defaults to Zeerex 2.0.
1877 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1879 --- 2.0.11 2004/02/16
1881 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1884 Added init command for yaz-client which sends "extra" init request.
1886 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1887 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1889 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1891 Make ZOOM error code for "invalid query".
1893 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1895 --- 2.0.10 2004/02/05
1897 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1900 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1902 Added option -p <file> to make Generic Frontend Server to write PID file.
1904 Added option -D to put Generic Frontend Server in background on its own.
1906 Make ZOOM C recognize option "password". If unset, "pass" is used
1907 (for backwards compatibility).
1909 Fixed a bug in Generic Frontend Server that could make it crash if a
1910 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1913 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1914 Must be issued before open, in order to be in effect.
1916 --- 2.0.9-6 2004/01/12 Debian/Windows
1918 Make the SRU server more picky WRT unknown params, etc.
1920 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1922 New YAZ client command, options, that sets Z39.50 options.
1924 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1925 options from a string of tokens (one token for each option bit).
1927 Update SRW diagnostic code messages.
1929 --- 2.0.9-5 2004/01/07 Debian/Windows
1931 Handle user defined stylesheet for SRW/SRU.
1933 --- 2.0.9-4 2004/01/06 Debian/Windows
1935 Fix bug in decoding of Content-Length.
1937 --- 2.0.9-3 2004/01/06 Debian/Windows
1939 Fix a bug with decoding of XML packed records.
1941 --- 2.0.9-2 2004/01/05 Debian only
1943 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1945 Fix bug in SRW/SRU diagnostics decoding.
1947 --- 2.0.9 2004/01/05
1949 Fixed bug in Generic Frontend Server which could drop records exceeding
1950 preferred message size. Reported and fixed by Irina Dijour.
1952 Fixed calculation of package size for structured records in Generic
1953 Frontend Server. Reported and fixed by Irina Dijour.
1955 Fixed namespace for SRW/SRU diagnostics.
1957 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1959 --- 2.0.8 2003/12/22
1961 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1962 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1965 CQL changes to reflect recent changes to the specification:
1966 * Documentation talks about context sets instead of index sets.
1967 * Documentation talks about indexes instead of qualifiers.
1968 * The CQL-to-PQF transformer's configuration file now uses
1969 "index.set.name = <attributes>" instead of the old form
1970 "qualifier.set.name = <attributes>". (Both forms are still
1971 understood but the latter is deprecated.)
1972 * CQL terms with no explicit index specified are now interpreted as
1973 cql.serverChoice instead of srw.serverChoice (which of course
1974 behaves exactly the same.)
1976 --- 2.0.7 2003/12/16
1978 MARC conversion can now generate ISO2709 output in another
1979 character set. yaz-marcdump uses this facility if you invoke it
1982 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1983 functions from there can be used from C++.
1985 --- 2.0.6 2003/12/04
1987 Frontend server now transfers memory from decoded packages to stream
1990 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1991 references to show up.
1993 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1994 the ZOOM Abstract API. The older names for the same options are still
1995 also supported for the benefit of old applications.
1997 ZOOM-C supports "implementationId" and "implementationVersion" options
1998 to go along with "implementationName". These allow the user code to
1999 specify identification strings to be sent to servers.
2000 Add OID for the new ExtLite attribute set.
2002 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2003 as requested/supplid by Ere Maijala <ere@atp.fi>
2005 For generic frontend server, reverse the order of
2006 "toolkit-supplied / application-supplied" strings sent as implementationId,
2007 Name and Version. Also, remove the spaces around the slash. This brings
2008 the GFS in line with the behaviour of ZOOM-C on the client side.
2010 Add function ZOOM_scanset_display_term.
2012 yaz-client shows scan displayTerm if present.
2014 Utility yaz-iconv is now installed by default along with the man page
2017 Extend configure check for OpenSSL to use pkg-config where available (such
2020 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2021 server to specify uid/gid/mask for socket using the format
2022 unix:[user=uid,][group=gid,][umask=mask,]file=path
2023 If file= is omitted the existing format is assumed, e.g.
2025 in which case the mask is 0666 (rw for everybody).
2027 Major restructure of YAZ source. All source in libyaz is in src directory.
2028 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2029 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2031 Added man page for utility yaz-marcdump (used to be called marcdump).
2032 yaz-marcdump is installed by 'make install'.
2034 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2035 of incoming package failed.
2037 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2039 Change prototype of odr_perror: add const to message string.
2041 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2043 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2044 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2045 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2046 DNS lookup. There should not be any compatibility problems with this
2047 assuming that blocking=1 or 0 is used.
2049 Fix bad reference in UNIX comstack in function cs_addrstr.
2051 Fix for compilation on AIX.
2053 The generic front-end server (server/seshigh.c) now supports returning
2054 Init diagnostics to the client in User-information-field, in
2055 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2058 --- 2.0.4 2003/09/04
2060 Allow any CQL relation (not just all,any,exact,scr).
2062 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2063 that features the same UI.
2065 Implemented command update0 in YAZ client which is equivalent to
2066 update but uses old of Ext Update ASN.1.
2068 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2069 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2070 Previously no OID was used for this info.
2072 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2073 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2074 returns 'malformed search term' otherwise.
2076 SortResponse member resultCount now set to NULL in sort handler of
2079 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2082 Add three new utility functions for translating OIDs between various
2083 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2084 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2085 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2086 char *oid_to_dotstring(const int *oid, char *oidbuf);
2087 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2089 Reverted modifications for ES Update definition for z_IU0Update
2090 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2091 is back to YAZ 2.0.2.
2093 String value attributes for CCL parser.
2095 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2096 which their FirstSearch server returns in Init responses, sometimes
2097 carrying useful diagnostic information when Init fails. This has the
2098 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2099 "z39.50/oclcui.asn", where its definition is somewhat different from
2100 what OCLC document on their web-site, as required to interoperate with
2103 Support for anonymous authentication in yaz-client. Use the command
2106 * Fix the OID of the Index Data-local "admin" Extended Service from
2107 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2108 the 1000, which indicates a locally-defined OID, was a mistake.
2110 --- 2.0.3 2003/06/20
2112 Fix CCL directive @case handling so that it affects string match for
2113 both CCL keywords and qualifiers.
2115 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2116 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2117 Decoder has been updated with ASN.1 changes as listed in
2118 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2119 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2120 z_IUUpdate, remains unchanged.
2122 ZOOM_record_get may now return a record in a specific character set.
2123 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2124 "from" is the character set of record as returned by target. "to" is
2125 the character set to be returned. If omitted, "to" is UTF-8.
2127 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2129 New ODR utility, odr_getelement, which returns name of element for
2130 which encoding/decoding failed.
2132 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2133 in cases where a required element was omitted.
2135 Bug fix: some MARC8 sequences were not converted.
2137 New ZOOM option "step" which specifies number of records to be
2138 retrieved in one chunk. Used in conjunction with "start" and "count".
2140 SRW support for yaz-client. Use scheme http: to use it, e.g.
2143 yaz-client no longer does (un)intelligent character set conversions
2144 by default. Can be enabled with charset and marc_charset commands.
2146 xmalloc trace fix for 64-bit systems such as DEC alpha.
2148 Solaris 2.6 compile fix.
2150 New function, cql_strerror() translates SRW error codes, as returned
2151 by cql_transform_error(), into human-readable English strings. Used
2152 in yaz-client diagnostics when appropriate.
2154 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2155 converts it into a type-1 query which is sent to the server. This
2156 makes CQL available for use with all Z-servers, as opposed to the tiny
2157 minority that can handle CQL queries themselves.
2159 --- 2.0.2 2003/04/28
2161 New Debian package layout similar to the Redhat Package layout.
2163 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2164 and search result respectively.
2166 --- 2.0.1 2003/04/25
2168 Redhat package is now several packages: libyaz (runtime libraries),
2169 libyaz-devel (development and documentation, and yaz (utility programs).
2170 Package spec file by Morten Bogeskov.
2172 New member 'schema' in struct bend_fetch_rr which the name of requested
2173 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2174 handler MAY set this to reflect the schema of the returned record.
2176 New member 'display_term' in struct scan_entry. GFS now sets member entries
2177 and allocates scan entries to be filled by user scan handler. In previous
2178 version, entries member was allocated by the scan handler. That still works,
2179 but the GFS will ignore member display_term - assuming it was NOT set by
2180 the handler. The fact that the GFS now allocates the entries both allows
2181 for new members and makes a scan handler easier to write.
2183 Fix CQL lex buffer overflow.
2185 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2186 SRU default recordPacking is string.
2188 SRU protocol support for frontend server.
2190 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2192 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2194 Added scan for the ZOOM shell (zoomsh).
2198 * String Identifers for Schemas (Amendment 5).
2199 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2200 Old definition for schema
2201 Odr_oid *schema; /* OPT */
2206 Z_InternationalString *uri;
2207 #define Z_Schema_oid 1
2208 #define Z_Schema_uri 2
2211 * resultCount parameter to Sort Response (Amendment 1).
2212 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2214 Support for SRW 1.0 over HTTP. This is an optional feature and
2215 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2218 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2219 on the same port. SRW SearchRetrieveRequests are mapped
2220 to bend_init,bend_search,bend_fetch,bend_close.
2222 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2224 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2225 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2227 ZOOM connections are SRW based if schem http is used for hostname
2228 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2229 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2231 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2232 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2233 distance=n, order=true/false, relation=le, prox unit=word. If
2234 n is omitted, distance 1 is used.
2236 Fixed problem with C compiler include path in wrong order.
2238 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2239 on Solaris. Patch from Ko van der Sloot.
2241 New MARC decode API. All new functions operate on a yaz_marc_t
2242 handle. The most important new functions are: yaz_marc_create,
2243 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2244 decode and destroy respectively. Decoder can produce formats
2245 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2246 include/yaz/marcdisp.h.
2248 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2249 to UTF-8, UCS-32, wchar_t or Latin-1.
2251 * Prototypes for yaz_iconv_-functions moved to separate header
2252 include/yaz/yaz-iconv.h.
2254 Make a few private functions 'static' in unix.c. This prevents
2255 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2257 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2258 are set when Init Response is received.
2260 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2261 but returns diagnostic set as well.
2263 New function yaz_strerror which is a portable wrapper for
2264 strerror/strerror_r/GetLastMessage.
2266 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2267 is returned for MARC. If type is "oai", then OAI MARC is returned.
2269 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2272 --- 1.9.2 2002/11/26
2274 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2276 Fix bad race conditions on SIGTERM and terminate gracefully in
2279 Move retrieval (data1) module to Zebra since nobody seems to be
2282 Add GRS-1 render for ZOOM using same format as yaz-client.
2284 --- 1.9.1 2002/10/05
2286 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2288 Fix broken ESpec handling in data1 module.
2290 SGML reader parses comments and makes them part of the data1 tree.
2292 Added several type casts so that YAZ compiles as C++ code.
2294 ZOOM didn't handle PDU encoding failures properly.
2296 Added more Bib-1 diagnostics (approved extensions).
2298 GNU configure: better check for iconv.
2300 More portable use of accept, getpeername. Check for socklen_t. Use
2301 int/size_t if socklen_t is not defined.
2305 PQF parser rejects bad queries - including those with extra
2306 characters in them. PQF parser used to silently ignore that.
2307 Cleaner API for PQF added, which allows you to get detailed
2308 error information for bad queries (see yaz/pquery.h).
2310 Fixed bug in ZOOM_record_get for type "database".
2312 Implemented mini iconv library supporting conversions between
2313 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2315 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2317 --- 1.8.9 2002/08/20
2319 Fixed ZOOM C record cache so that preferredRecordSyntax and
2320 elementSetName is used to check for already fetched records.
2322 --- 1.8.8 2002/08/02
2324 Added three members in bend_initrequest structure to facilitate
2325 character set negotiation.
2327 Fixed a bug in frontend server that could cause indefinite
2328 loops under rare conditions.
2330 Revised character set utilities (charneg.h) so that encoding
2331 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2333 For PQF, directive @term <type> sets term type for Scan/Search.
2334 Here <type> is general, string, numeric, null. The term type
2335 is inherited - just like @attr.
2337 New call odr_set_charset that sets character set conversion for
2338 international-strings on a ODR stream. Prototype is:
2339 int odr_set_charset(ODR o, const char *to, const char *from);
2340 The InternationalString is still represented as C string in YAZ
2341 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2342 won't). On the protocol level, you can use any encoding.
2344 Support for UNIX sockets in ZOOM.
2346 Solaris recv sometimes returns errno == ENOENT. It is treated as
2347 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2349 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2350 both client and server. Code by Morten Bogeskov.
2352 --- 1.8.7 2002/05/22
2354 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2355 that they can be used directly from Visual Basic. You must recompile
2356 your windows APP if you're using ZOOM.
2358 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2359 Commands "lang" and "charset" sets language and character set respectively.
2360 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2361 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2363 Attributes from multiple CCL fields may be OR'ed rather than merged
2364 using directive "@field or". Fields are still merged by default -
2365 equivalent to "@field merge".
2367 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2370 Fixed bug in zget for parameter ExtendedServicesResponse.
2374 --- 1.8.6 2002/03/25
2376 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2378 Client displays USR.1:SearchResult-1 (hits per term).
2380 Additional Search Info for search in Generic Frontend Server.
2382 Fixed CCL parsing of "field=s".
2384 WIN32 installer - using the excellent NSIS software from nullsoft.
2386 Fixed CCL parsing of "field = - <number>".
2388 Added function yaz_marc_decode that decodes MARC for line mode
2389 display or XML (similar to that used by JZKit).
2391 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2392 Z39.50. But ISO/ILL was, however.
2394 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2395 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2397 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2398 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2400 --- 1.8.5 2002/02/03
2402 New YAZ client features: Command completion and new commands:
2403 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2404 Code provided by Jacob Poulsen.
2406 New call oid_trav, that visits all registered OIDs via callback.
2408 Function ZOOM_record_get now returns const char pointer rather than
2409 void pointer. It saves a lot of type casts.
2411 For YAZ client, command "auth" now allows you to set authentication
2412 in IdPass style. It is enabled when three tokens are given - order
2413 is user, group and password.
2415 Fix memory leaks in MARC record handling for ZOOM.
2417 New option for YAZ client, -k <kilobytes> that sets
2418 maximum record size. Similar to -k option for generic frontend
2419 server and yaz-ztest.
2421 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2423 Prefix query parser reports "fail" when bad attribute set is given.
2425 Fix in MARC decoder. Proximity logging. Fix for attribute set
2426 in scan handler for server. Patches by Shigeru Ishida.
2428 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2431 Configure option --with-openssl=<dir> now works when a directory is
2432 specified. Patch provided by Morten Bogeskov.
2434 New option for YAZ client, -u <auth>, that sets authentication.
2436 ZOOM fix: error information was sometimes "missing", since error
2437 was cleared/reset too when it shouldn't.
2439 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2441 --- 1.8.4 2002/01/04
2443 Scan for ZOOM API. New object ZOOM_scanset. New functions
2444 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2445 ZOOM_scanset_destroy.
2447 New ZOOM function, ZOOM_connection_last_event, that returns type
2448 of last event (such as "receive data", "send data", "apdu received",
2451 New ZOOM option, schema, that specifies schema for retrieval.
2453 New CCL feature. Qualifiers can be aliases for one or more
2454 other qualifiers (if more than one is given, OR is used).
2456 ZOOM uses named result sets if target supports it.
2458 Two new YAZ client commands: . (dot, which sources a script of YAZ
2459 client commands), and ! (to execute shell command.). Implemented
2462 Working on Debian packages.
2464 --- 1.8.3 2001/11/19
2466 YAZ client enables named result sets only if target supports it.
2468 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2470 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2471 with key="host" to get same result.
2473 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2474 Function Z3950_resultset_record(s) returns references to records
2475 "owned" by resultset. To become owner use Z3950_record_clone.
2477 Function z_ext_record handles Extended Services. Thanks to
2480 --- 1.8.2 2001/11/12
2482 CCL Parser fix: ignore token comma when dealing with and-lists.
2484 Documentation updates for COMSTACK.
2486 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2487 Changed prototype Z3950_records. For some functions, int parameters
2488 were changed to size_t.
2490 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2493 New MARC decode/display function, marc_display_exl, which properly rejects
2494 non-ISO2709 records. YAZ client uses it.
2496 --- 1.8.1 2001/10/29
2498 Fix bug: local attribute set wasn't set correctly in PQF strings.
2502 * Old Z39.50 codecs no longer supported.
2504 Added ZOOM C binding. See http://zoom.z3950.org/
2506 Renamed states for COMSTACKs to avoid confusion with events.
2508 Implemented cs_look and proper cs_rcvconnect.
2510 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2512 Configure detects POSIX threads on OpenBSD.
2514 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2515 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2517 When error is returned from present handler, non-surrogate diagnostic
2518 is returned in present response (and fetch handler is no longer called).
2520 * Minor adjustments to pquery parser (PQF). Token characters may be
2521 escaped by using backslash (C-style).
2523 PQF parser allows string attribute values to be specified. For @attr,
2524 non-numeric characters after the equal-sign are treated as strings
2525 (e.g. @attr 9=title).
2527 CCL trunction character may be defined (@truncation in file)
2529 * function zget_ExtendedServicesRequest sets waitAction to
2530 waitIfPossible (was wait).
2532 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2535 CCL operator names may be set in field definition files (CCL_bibset).
2536 See ccl/bib1 for an example.
2538 Fixes in ASN.1 compiler for C++ compatibility.
2540 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2541 and "op_or" to avoid conflict with C++.
2543 Fixed problem with GNU readline detection on Redhat 7.0.
2545 Added step-size for Scan backend handler.
2547 Fixed bug that made the frontend server crash when no attribute
2548 set was specified for scan.
2550 Front-end server automatically switches to original working directory
2551 when installed as an NT service. Previously -w had to be specified to
2554 Added extended attributes for retrieval module (data1), so that data1
2555 records carry d1_readXML/SGML attributes. d1_read also supports
2556 null-data rules ( <tag/>)
2558 On UNIX when POSIX threads are available, a separate library libyazthread
2559 is created. Programmers should link with that library and the yaz library
2560 when using threads. The reason for the split was that some applications
2561 on Linux, such as Apache, doesn't work well when using shared objects that
2564 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2565 (or any frontend server) in SSL mode by specifying ssl: followed by
2566 address. Only tested on UNIX.
2568 Added feature for CCL module. Virtual structure s=al or s=ol generates
2569 and-list and or-list respectively instead of phrase search.
2573 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2574 log_mask_str. This was done to avoid name conflicts with other libraries
2575 (such as other PHP extensions).
2577 Added raw OID member for preferred record syntax (request_format_raw)
2578 and returned record syntax (output_format_raw) for backend fetch method.
2580 Config file yaz-config now accepts options so that it returns specific
2581 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2583 Shared library support for UNIX using GNU libtool.
2585 * Modified backend interface. Request/Response struct's replaced by
2586 one read/write C struct. For example bend_fetchrequest and
2587 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2588 Every handler - even search has to be registered in bend_init
2589 handler. This means that the YAZ library no longer refers to
2590 external functions and it makes it possible to make the whole
2591 thing a single DLL/SO.
2593 Added Segment handler for backend server.
2595 Added Zmbol/Zebra administrative functions to YAZ client.
2597 Threaded frontend server on UNIX (when POSIX Threads are available).
2598 Starting the server with option -T enables multi-threading.
2602 Added configure option --enable-comp/disable-comp to control use
2603 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2604 located in sub directory asn.
2606 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2607 in ${exec_prefix}/bin along with the other programs yaz-client and
2610 GNU automake used to maintain makefiles.
2612 Added several OID's.
2614 Changed retrieval module so that we can load records with no abstract
2615 syntax defined. Tagpaths in these records are fully composed of string
2618 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2622 On UNIX, the generated makefile now supports a proper 'make install'.
2623 The prefix can be set via GNU configure to set the install location
2624 (default is /usr/local).
2626 * YAZ programs client and ztest were renamed to yaz-client and
2627 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2628 locations, such as /usr/bin,/usr/local/bin,etc.
2630 * YAZ Header files were moved from include to include/yaz. YAZ Header
2631 files are referred to as include <yaz/log.h> rather than <log.h>.
2632 The YAZ include path (-I ..) is therefore the same as before. Programmers
2633 should update their #include statements or use -Ipath/include/yaz
2634 instead. The main motivation for doing this change is that YAZ header files
2635 can be installed in "standard" locations /usr/include,/usr/local/include
2636 without introducing conflicts, since ALL YAZ header files are stored
2637 in subdirectory yaz (under /usr/include for example).
2639 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2640 rather than project/workspace files. We switched because project files
2641 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2644 Changed name of logging function, logf, to yaz_log, to prevent name
2645 clash with some math-log functions. The YAZ header log.h defines logf
2646 to yaz_log (#define) so there should be no incompatibilities by this
2649 Added bend_start/bend_stop handlers for server. These handler are
2650 called on start/stop of server. For windows they are called whenever
2651 a service is started/stopped.
2653 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2654 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2655 in util/yc.tcl. The auto-generated C code structures are, in a few
2656 cases, incompatible with the old decoders. There are differences in the
2657 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2658 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2659 The preprocessor variable ASN_COMPILED is defined when the compiled
2660 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2661 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2662 wish to use the old encoders/decoders you can specify --disable-yc
2665 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2666 version so that it supports both new - and old version of DB Update
2668 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2669 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2670 change. The name parameter can be set to 0 in which no name is specified
2671 for the construction. The macros odr_implicit and odr_explicit sets name
2672 parameter to zero for the construction involved. New macros
2673 odr_implicit_tag and odr_explicit_tag are similar to the others,
2674 except that a name parameter is added. For programmers' that don't use
2675 ODR they probably only need to change the call to z_APDU and z_External.
2677 Added access control facility by interfacing the TCP wrapper library.
2678 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2679 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2680 name of the daemon and enables the access control as specified in
2681 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2683 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2684 den Dool <H.M.vdnDool@kub.nl>.
2686 Added reference ID parameter to most functions in server API - refer
2687 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2689 Changed name of ccl library to libccl.a (was ccl.a).
2691 Fixed bug in decoder for Explain (Category TargetInfo).
2693 Added support for GNU readline in client. Thanks to Jacob Poulsen
2694 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2696 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2697 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2698 IMPLEMENTATION! This change was made to the development version before
2699 the ZIG decided to retract the amendment. If any users MUST be
2700 compatible with the original Update definition, PLEASE CONTACT US, and
2701 we will include a separate definition corresponding to the old Update
2702 ES. Note that because of the change to the ASN.1 of the
2703 TaskPackageRecordStructure we cannot define a single structure that
2704 will support both versions.
2706 * Added const modifier to buffer parameter for some ODR/BER encoding
2707 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2708 completeWAIS, odr_dumpBER.
2710 Fixed bug in client.c which caused a crash when a scanResponse didn't
2711 contain positionOfTerm.
2713 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2714 * will cause an error in a client if a non-YAZ target sends both a
2715 * list of Scan entries and non-surrogate diagnostics.
2717 Retrieval module enhancements. Tag sets may be typed in the reference
2718 to it. From the .abs-file the "tagset" directive takes a third optional
2719 integer type for the tag set referenced. From a .tag-file the "include"
2720 directive takes a third optional type as well. The old "type" directive
2721 in the tag set itself is still recognized but acts as the default type
2724 Backend interface change. Individual Scan terms returned from bend_scan
2725 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2726 in include/backend.h.
2728 Retrieval module enhancements. Multiple tag sets and attribute sets may
2729 be specified in abstract syntax specs. Revised the error/warning for
2730 logging messages reported by the retrieval module when reading the
2733 Object Identifier system (oid_..) changed. The API is backwards
2734 compatible but the oid-routines now allocates new OID's when needed.
2735 Raw OID's may be specified in oid_getvalbyname.
2737 YAZ now uses GNU configure to generate Makefile(s).
2739 * Minor changes in some of the member names of DeleteResultSetRequest and
2740 DeleteResultSetResponse. See include/proto.h.
2742 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2743 and added member 'languages' in TargetInfo (which was missing).
2745 Changed the way attribute sets are handled in the retrieval
2746 module. These are now cached, just like the abstract syntaxes
2749 Changed YAZ so that it links with compiled ASN.1.
2751 Added Explain-schema definitions and mapping routines. The following
2752 Explain categories have been implemented: AttributeDetails,
2753 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2755 Fixed minor bug in Windows version of Server Library.
2757 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2759 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2761 Added EXTERNAL: UNIverse Resource Report (non-standard).
2763 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2764 ENUMERATED and SET OF.
2766 * Added 'const' to some of the char pointer arguments for the
2767 functions, data1_read_node, data1_getelementbytagname,
2768 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2771 Fixed bug in data1_insert_taggeddata - the last_child member of
2772 parent wasn't initialised.
2774 * Changed data1_read_record and data1_read_node so that the supplied
2775 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2776 doesn't refer to any parts of the "SGML"-buffer.
2778 Fixed bug in server library (Windows version of statserv_remove).
2780 * Changed code so that it compiles as C++. The type definition
2781 of Odr_fun which is a member of Odr_arm was changed. The result is,
2782 that an explicit typecast is needed for the fun pointer when
2783 using Odr_arm - as in:
2784 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2786 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2788 Implemented the new structured date and time definition as approved
2789 by the ZIG. Added schemaId element to the specificTag in Espec-1
2790 (also approved at the last ZIG). Thanks to RVDM.
2792 Added some Object identifiers (RVDM).
2794 Changed the Update Extended Service (RVDM).
2796 Added command "refid" to client which specifies referenceId for
2797 the following requests.
2799 Implemented extended service handling for server. See ztest.c
2800 for an example as well as backend.h. New handlers are registerd
2801 in the Init handler.
2803 * Changed interface for sort in server.
2805 Added new members to statserv_options_block. It allows a server
2806 to read options from another source than just the command line. Thanks
2807 to Charles Woodfield.
2809 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2810 renamed to zboolean. Some C++ compilers complained about the name.
2812 Minor changes to gils.abs. Added index 's' (sort) on title
2813 and date/time-last-modified.
2815 --- 1.4pl2 1998/1/30
2817 Fixed bug in server library regarding inetd mode (-i). This bug
2818 was introduced by release 1.4.
2820 --- 1.4pl1 1998/1/29
2822 Added sort facility in client and backend server interface.
2824 Fixed problem with dependencies in Makefile(s).
2826 Fixed bugs for encoders/decoders of extended services and
2829 Implemented sub-tree feature for schemas. Sub-trees are
2830 referenced in *.abs-files. See explain.abs for an example
2831 of the use of this feature.
2833 Modified bib1.att; local attributes for ANY didn't include
2834 ANY itself (only affects use of the retrieval module).
2836 Fixed bug in plain SGML reader in function data1_read_node:
2837 tags with prefix "var" was incorrectly interpreted as variants.
2839 Added feature "sub-schemas" to enable references to - and definitions
2840 of - group of elements.
2842 * Removed member parent from type data1_element (in data1.h).
2844 Implemented function odr_nullval() that returns the value of
2847 * Removed member num_children from data1_node (in data1.h).
2849 Made NT service interface part of the server library. The
2850 function statserv_main uses the NT service when required and
2851 calls the statserv_start / statserv_close routines.
2853 Routine zget_SearchRequest and zget_PresentRequest fills
2854 resultSetName/Id member with "default" instead of "Default".
2856 Fixed memory leak in server. Request queue member wasn't freed.
2858 Fixed nmem_exit so that memory is freed.
2862 Revised the CCL parser utility to be thread safe.
2864 Added function, oid_ent_to_oid, to replace the function
2865 oid_getoidbyent, which is not thread safe.
2867 * Added nmem_init and nmem_exit to initialize and release
2868 NMEM resources. Function nmem_init should be called once in the
2869 initial thread before NMEM/ODR is used. statserv.c and client.c
2870 have been changed accordingly. The change was necessary to make
2871 NMEM thread safe. The NMEM memory pool is shared amongst threads
2872 in a process. Unix-based applications will still work fine without
2875 Added NT Services interface for the the Z39.50 (statserv) Server.
2876 Refer to the ztest.c source on the usage.
2878 Windows 95/NT port using MSVC5.0. Project files are included in the
2881 * Defined new 'global' handle for the retrieval (data1) system. The
2882 new handled, data1_handle, describes the state of the data1 system.
2883 This handle is passed as first argument to virtually all
2884 data1 related routines. The functions data1_create and data1_destroy
2885 creates and destroys a data1 handle respectively.
2887 Added ODR encode stream member to all backend request structures
2888 init, search, scan etc. This stream should be used to allocate all
2889 memory used for the response when thread safe operation is needed.
2891 Changed the comstack utility, cs_addstr, to be thread safe. The
2892 returned hostname string returned by the function is now part the
2895 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2896 function. The cs_straddr takes a COMSTACK handle as argument, so this
2897 function must be used after cs_create and before bind/connect.
2898 This function is thread safe.
2900 Moved test server to 'ztest' directory - generic server code still
2901 in 'server' directory.
2903 Made prefix query (pquery.c) utility thread safe.
2905 Added new function modifier YAZ_EXPORT to 'export' public DLL
2906 functions when using windows (see include/yconfig.h).
2908 Added definitions to the OID database (util/oid.c) (RVDM).
2910 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2912 Added call to ccl_rpn_delete in client program.
2914 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2915 release of RPN structure.
2917 Added support for C++, headers uses extern "C" for public definitions.
2918 With input from RVDM.
2920 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2921 Thanks to Ronald van der Meer (RVDM).
2923 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2925 Added support for private extensions to the OID database
2926 (oid_setprivateoids()). Thanks to RVDM.
2928 Added optional, physical ANY (key replication)
2930 Fixed null-reference problem in GRS-1 output filter.
2932 Proximity operator added to Prefix Query Format (PQF).
2934 In test client command "base" accepts multiple databases.
2936 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2940 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2942 Smallish bug-fixes in the new encoders/decoders (explain).
2944 Bug fixed in DeleteRequest.
2946 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2948 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2950 Added SOIF syntax (using private OID for now) to retrieval module and client.
2952 Added Update extended service.
2954 Added SearchResult-1 additional info structure.
2956 Added optional CCL (ISO8777) interpreter as separate module. Available
2959 --- 1.2 1996/6/10 (1st anniversary release)
2961 Added Summary record syntax. Lightly tested.
2963 Added OPAC record syntax. Untested.
2965 Added ResourceReport service encoders/decoders. Untested.
2967 Fixed bug in z_Unit - wrong tagging on unitSystem.
2969 Fixed bug in the DiagRecs decoder.
2971 Added options for max PDU size and session timeout to frontend-server.
2973 Added documentation of query-language parsers and other supporting utilities.
2975 [frontend-server] Added Attribute set to the bend_scanrequest API.
2977 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2978 surrogate diagnostics were generated.
2980 [retrieval] Allow multiple local values for attribute.
2982 [retrieval] Allow multiple attributes per element in .abs files. index type.
2984 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2986 --- 1.1pl2 1996/4/10
2988 Minor changes, mostly specific to Zebra's requirements (retrieval)
2992 Repaired bug in frontend server when running multiple listening
2993 endpoints in dynamic mode.
2995 z_External() now won't break if a known, ASN.1 value comes encapsulated
2996 in an octet-string. The value will pass through unmodified in an Odr_oct.
2998 Added a bit of code to the demo client to decode & display
2999 ASN.1-structured records represented in the octet-aligned branch of
3000 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3002 Added z_ext_getentbyref() to the ASN module. Doc updated.
3004 * Completed the SCAN definition in the ASN module. This may break SCAN
3005 code based on older YAZ-versions at compile-time. The fix is easy -
3008 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3009 under the SCAN definition. Remember to initialize this, server-people.
3011 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3012 that this does not extend to ODR and ASN.
3014 Comstack allows insertion of established socket (primarily for
3015 inetd-operation of servers). Doc updated.
3017 Front-end server can now start from the inetd in TCP mode. Doc
3020 --- 1.0pl4 1996/1/24
3024 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3025 the rank and record number.
3027 Adjustments to the frontend server.
3029 Fixed diagnostic BER dumper. It ignored the file argument.
3033 Various changes to retrieval module.
3035 Changed the union discriminators of the protocol files from enums to
3036 ints paired with #defines.
3038 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3041 *Changed operator in the RPN structure to 'roperator', again to avoid a
3044 Fixed problems in Explain decoders/encoders.
3046 --- 1.0pl2 1995/12/6
3048 Memory bug in log module fixed.
3050 --- 1.0pl1 1995/12/5
3052 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3054 Bug in Explain DatabaseInfo module fixed.
3056 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3060 The shift to v1.0 signals that we now consider the *core* functionality
3061 of YAZ reasonably stable (the core being more or less equivalent to
3062 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3063 tested (Explain not at all - though that will happen soonish).
3065 Minor changes to code to support Windows port.
3067 Various minor changes after we're getting to use GRS-1 & co. more.
3069 Added Espec-1 format.
3071 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3072 of the protocol and it cannot be selected when encoding (maps into 'string'
3073 when decoding). Needed to talk to some servers.
3075 Demo client can request simple element set names.
3077 Added Diagnostic Format encoders/decoders.
3079 Added simple Close handling to frontend server (no hooks for resource
3080 reporting yet), and demonstration client.
3082 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3084 --- 1.0b3 1995/08/24
3086 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3087 handled incorrectly when records were requested in the searchResponse. This
3088 will only affect you if you use the frontend-server.
3090 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3091 Test-client will ask for and print GRS1. Ztest will return dummy records
3094 Added Explain encoders/decoders to the service-level API. Untested.
3096 Added Extended Services: Item Order encoders and decoders to the Service-
3097 level API. Untested. We could use a recent copy of the pertinent bits
3098 of the ILL protocol to add those bits.
3100 Added diagnostic format 1 encoders/decoders to the service-level API.
3103 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3104 odr_cons.c, which causes a more correct output.
3106 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3107 was always set to 0 when no records were requested in the searchRequest.
3109 * Added better external-handling. This shouldn't harm old code that
3110 *encodes* externals. It can break code that looks for a
3111 'single-ASN1-type' representation, since those types that are known
3112 are now decoded immediately. Look at the SUTRS sample code in
3113 seshigh.c and client.c. Documentation updated.
3115 Handling of structured records in bend_fetchresponse. Length -1 marks
3116 structured record, type is deduced from format field.
3118 --- 1.0b2 1995/06/27
3119 Fairly quick maintenance release to add SUTRS support.
3121 Fixed handling of SUTRS records in the demonstration client.
3123 * Added format field to the bend_fetchrequest and bend_fetchresponce
3124 structures of the backend API (frontend server). When the record is
3125 returned, the value of the format field is mapped to an OID. The
3126 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3127 of the record. The special value VAL_NONE in the bend_request means
3128 that no specific format was requested by the client. Documentation
3129 updated accordingly. Test server (ztest) will return a fixed dummy
3130 SUTRS record if your client requests SUTRS.
3132 Documentation updated accordingly.
3134 You can now set external libraries and RANLIB support in the top-level
3138 First public release.
