3 record_conv: leader spec may be given for marc element.
4 The leader spec is given as attribute leaderspec for element marc.
5 For example to convert a MARC21 record from MARC-8 to UTF-8:
6 <marc inputformat="marc" outputformat="marc"
7 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
9 record_conv: allow user-XSLT params. For example:
10 <xslt stylesheet="MARC21slim2DC.xsl">
11 <param name="myparameter" value="myvalue"/>
12 <param name="otherparameter" value="othervalue"/>
15 record_conv: fix error handling for missing marc charsets.
17 CQL: fix extra terms in wrong order.
21 record_conv: modify new API for conversion types. The conversion types
22 may be passed in new functions yaz_record_conv_configure_t and
23 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
25 Avoid mixed statement/variable declare; fixes compilation with Visual
30 Add non-standard SRU diagnostic: 235: "Database does not exist".
31 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
32 Update SRU to Bib-1 diagnostic maps accordingly.
34 CCL: add two new diagnostics for unsupported masking. The new
35 diagnostics are: "Embedded truncation not supported" and
36 "Single charcacter mask not supported".
40 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
44 Build YAZ for Ubuntu Oneiric.
46 CCL: allow parantheses for proximity operands. For example CCL query
47 (a) % (b) is now allowed.
49 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
50 marked dead, rather then being destroyed. If not, the session memory is
51 being free'd before the search/scan handler is finished. Also destroy
52 'request' memory in request_release rather than in various places,
53 which resulted in leaks from time to time.
57 cql_sortby_to_sortkeys: honor sort prefix.
59 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
60 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
61 The rpn2cql family of functions now always returns quoted CQL terms.
63 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
67 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
68 sequence is treated as one. For example, &&a=b&&&c& is identical to
73 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
74 APDUs for a connection to a WRBUF.
78 Fix cql_sortby_to_sortkeys. Completely broken before.
80 Make CCL's @truncation work again.
84 New ZOOM connection setting: tproxy. It's like proxy, but does not
85 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
86 to set resolved address + port for a connection outside ZOOM itself.
88 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
92 Fix uninitialized variable in Solr spell support (could cause SEGV
93 for SRU response decoding).
95 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
96 back-end's addinfo through into the ZOOM response addinfo.
98 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
99 they are separated by a colon and a space rather than simply
102 --- 4.2.18 2011/10/28
104 Add support for Solr spell-checking/suggestions through ZOOM.
105 If a Solr target has been configured correctly for spelling-checking
106 and suggestions, these will now be returned on the ResultSet option
107 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
109 --- 4.2.17 2011/09/28
111 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
112 with a flag whether to substitute escape sequences or not.
114 --- 4.2.16 2011/09/22
116 Fix nmem_strsplit_escape to substitute escape char properly.
118 New option for zoomsh -e , which makes it abort on first error and
119 return process exit code to indicate success/failure.
121 YAZ options utility supports special option -- which makes all it treat
122 all following arguments as non-options.
124 --- 4.2.15 2011/09/16
126 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
127 searched if absolute filename is given.
129 Fix conv_xslt() error-reporting when stylesheet is not found.
130 (The value of fullpath is meaningless in this situation.)
132 --- 4.2.14 2011/09/07
134 Fix problem in CQL sort node creation: un-initialized memory.
136 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
137 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
138 CQL sortby depending on whether Type-1 or CQL is actually sent to the
141 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
142 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
144 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
145 will make it possible to use both single-character mask (#) and wildcard (?)
146 in CCL . Throw diagnostic for left truncation because that is not supported
149 --- 4.2.13 2011/09/01
151 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
152 cases using escapes (\-sequences) and masking.
154 PQF parse fix: A trailing backslash followed by end-of-string (\0)
155 would result in a read one byte beyond string.
157 rpn2ccl may use Z39.50 masking for terms (t=z).
159 ICU check fix. Don't include library -lCrun on Solaris, unless present.
161 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
162 not --cppflags (which seeems like an error in icu-config).
164 --- 4.2.12 2011/08/27 RPM package only
166 cql2ccl: fix conversion of terms: operator characters were not
169 --- 4.2.11 2011/08/25 RPM package only
171 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
172 CCL parser will map both # and ? to their regular expression
173 quivalents (. and .*).
175 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
176 of reserved CQL characters.
178 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
179 is, so that they are passed through.
181 --- 4.2.10 2011/08/24
183 ZOOM SRU mode: more aggressive re-connect.
185 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
186 made available as a utility function, declared in <yaz/logrpn.h>
188 rpn2cql_structure() supports proximity nodes (except that the Type-1
189 proximity node's "exclusion" binary is ignored, as there is no way to
190 express that in CQL). Fixes bug #4564.
194 Fix SEGV that could occur if set command of zoomsh was given without
195 value (2nd argument).
197 Fix SEGV that could occur if unsupported transport was given for
198 COMSTACK - say https (when SSL was unavailable).
200 Build yaz-url on Windows too.
204 New utility to get web content. Header is url.h. A command line tool
205 yaz-url is part of the distribution and packages.
207 Fixes for SSL COMSTACK (when gnutls is in use).
209 New functions yaz_base64{encode,decode}. Header is base64.h.
213 ZOOM C includes HTTP response buffer as additional info if it fails
214 to decode the SRU response.
216 Make wrbuf_json_puts available.
220 zoom: throw diagnostic for invalid value for option "sru". Before a
221 bad SRU request was sent.
223 Adding new utility wrbuf_vp_puts.
225 Add cclxmlconfig.obj to win/makefile. It was missing completely.
229 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
230 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
231 redirect was used at the same time.
233 MARC line mode decoding: be less picky about length given - first
234 5 digits of header that is.
236 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
238 Changes to decoding of SRU records: a record with recordPacking=xml is
239 modified with a new root element <yaz_record> if the recordData contains
240 multiple children elements. This is to make the record XML parseable
243 RPN to SOLR conversion: encode special characters.
245 Generic Frontend Server: fix uinitialized member, stepSize.
249 Fix a bug in SRU decoding of records.. The database records stored
250 had un-initialized memory, but it would only be seen with yaz_record_render
251 and type_spec="ext" .
253 Fix a bug in ccl_qual_dup introduced in 4.2.3.
257 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
261 Add new utilities to convert from CQL to CCL . These utilities have
262 prefix cql_to_ccl defined in cql.h.
264 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
265 lead to memory heap corruptions when ICU utilities were in use.
269 Make compilation work without Libxml2.
271 yaz-client: remove redundant blanks in display of searchResult-1 term
276 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
277 resulting CQL node (tree) in a new node CQL_NODE_SORT.
279 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
280 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
281 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
282 Note that the CQL sortby spec is only converted when the GFS is already
283 converting from CQL to RPN (cql2rpn element).
285 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
286 specify whether to collapse delimitors or not. The existing nmem_strsplit
287 do collapse (collapse parameter = 1).
289 Windows installer: For NSIS, set InstallDir depending on x86/x64.
291 Rename internal func yaz_use_attribute_create. While non-static, this
292 function is not declared in a public header.
296 Add -lCrun when linking with ICU on Solaris.
298 More quicks character set conversions for OPAC records.
302 fix problem with record_render: records were converted (character set
303 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
307 SRU: add methods for handling DADS SRU-proxy facets.
309 Separate OPAC record character set for ZOOM_record. yaz_record_render
310 allows a character set given as charset=from/opacfrom,to where 'from' is
311 the character set of a bibliographic record, 'opacfrom' is character set
312 of OPAC record and 'to' is the target character set.
316 yaz-client: show may XML format records. Command show followed by 'format'
317 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
320 src/stemmer.c: Avoid using unnamed union. It is not supported by some
323 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
326 Update yaz.spec to operate on both SLES11 / Centos 5.5.
328 RPM: Release includes 'indexdata' name. Use indexdata in release name so
329 this package can be distinguished from other vendors.
331 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
332 as determined by configure
334 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
336 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
337 returns no error and no record, the present request is considered
338 partial (only a subset of the records could be returned by backend), and
339 so it is appropriate to set Present Status to partial-4.
343 Move yaz-config man pages to section 1.
345 More documentation about SOLR.
347 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
348 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
349 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
350 peers on some Linux systems. However, in general that does not work
351 so YAZ can not rely on that to work. Debian changed behavior in this
352 respect from Debian lenny to Debian squeeze (still testing as of Oct
354 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
356 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
360 Fix yaz-config output: echo_source not set correctly by configure.
364 SOLR WebService support for yaz-client and ZOOM.
366 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
368 --- 4.0.12 2010/08/17
370 Z39.50 facet support. Facet specifications are passed for search in
371 other-information with ASN.1 as defined in facet.asn and OID
372 .10.1000.81.5 . Facets are expressed as an Attribute list as known
373 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
374 3 is limit (number of entries to get in response). yaz-ztest returns
375 dummy facets if a client asks for them.
377 --- 4.0.11 2010/07/09
379 CCL fixes: bug 2895 and bug 3539.
381 GR1-display: add comma in display - was removed by mistake in
384 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
386 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
388 --- 4.0.10 2010/06/18
390 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
391 result set from a connection. The result set will be on its own
392 thereafter; no operations on it will perform retrievals from a target.
393 Only cached copies are returned.
395 ZOOM C:fix case for HTTP servers responding with Connection:close.
396 Ensure that if there is a current task it is resumed (like fetching
397 more records in a result set) . Bug #3484.
399 PQF parser: use odr_atoi for Odr_int (not atoi)
401 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
402 values that contain any non-digits are treated as string attributes
403 (previously decoding only checked for leading character ([0-9]). PQF
404 encoding: attribute string values are not surrounded by double-quotes.
408 New utility for managing threads - thread_create.h.
410 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
411 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
412 but YAZ' implementation do.
414 Fixes for yaz_cond-functions on Windows 7.
416 DLL export more symbols.
418 zoomsh: show record do NOT render opac.
420 Remove *.la files from Debian and RPM packages.
424 Debian package libyaz-dev depends on libgnutls-dev again (was
425 removed in YAZ 4.0.6, but due to Libtool it is still needed
426 even though yaz-config do not list libgnutls libs).
428 ZOOM: Use only one WRBUF for returning string results for
429 ZOOM_resultset. Reduces memory usage for ZOOM in general.
431 ZOOM: ZOOM_connection do not use a shared pointer to
432 ZOOM_resultset after ZOOM_resultset is destructed by
433 user. Reverts to YAZ 4.0.4 behavior.
437 record-conv: fix problem with at least one XSL conversion -
438 due to probably incorrect usage of XML XSL documents.
442 Fix yaz-config for static mode and the use of SSL (gnutls).
446 Forward decl timeval struct in mutex.h and gettimeofday.h.
448 yaz-config: fix 'static' mode linking.
452 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
453 are wrappers for pthreads or Windows. For Windows these are put in
454 a separate DLL: yaz_cond4.
456 libyaz.la (whole source) is compiled with thread. If thread support
457 is enabled enabled, all source of YAZ is compiled with treading support.
458 This allows core utilities such as yaz_log to use thread facilities.
459 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
460 thread utilities. This commit moves mutex utilities (mutex.c) from
461 libyaz_server.la to libyaz.la.
463 yaz-json-parse displays leading text until error.
467 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
468 patch from Giannis Kosmas.
470 SRU: no longer URL encode SRU database. The URL for an SRU server is
471 a URL and such is alreeady encoded - at least when given with leading
472 http:// or https://. This reverts behavior to YAZ 3.0.50.
474 Support for new MARC XML notation TurboMARC which like MARCXML is a
475 complete representation of MARC/ISO2709.. This one, however, is more
476 compact and allows for faster processing with XSLT. TurboMARC can be
477 used in the marcdisp.h API, from the yaz-marcdump utility and from
480 yaz-ztest can be configured - via the database - to perform certain
481 delays when it performs operations search, present and single record
482 fetch. This allows testers to make yaz-ztest act as a real or even slow
483 Z39.50 server. Refer to the yaz-ztest man pages for details.
487 wrbuf_destroy allows NULL WRBUF passed to it.
489 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
491 Add ZOOM_connection_close.
493 No fixed size buffers for ZOOM shell - bug #3257.
495 tstodr: make it work on s390 platform.
497 New icu iterator-functions. The new icu_iter-functions makes it possible
498 to use ICU chains from many threads.
500 yaz-client: better syntax check for show command.
504 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
507 New simple local-file XML include facility which allows file glob-patterns.
508 Refer to yaz/xml_include.h.
510 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
513 ZOOM_record_get supports new parameter "format" which makes it format XML
516 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
517 JSONText in ECMA-262) is JSONValue, not JSONObject.
521 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
522 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
524 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
525 POSIX/Unix builds .so with major version 4.
527 Remove old LOG_-defines from log.h. They have been obsolete and
528 undefined by default for the last 5 years.
530 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
532 GFS: Remove socket (int *fd) from search_rr handler. The socket
533 descriptor ptr is a facility that allowed a search handler to supply
534 a socket which would serve as a callback - when search was complete.
535 This facility has now been in use for years.
537 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
538 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
539 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
540 returns 'const char *' rather than 'char *. The returned string is
541 read-only and should not be modified by applications. COMSTACK cs_close is
542 now a void function - it no longer returns int. No applications check for
543 the value and the implementations has always returned 0.
545 ZOOM: use size_t for scan hit counts and str size. Functions
546 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
547 occ (hit count) and len (string length) are now of type size_t pointer
548 rather than int pointer. This is to be able to represent large hit counts
549 and to also just to use the proper type for string length (strlen result).
551 New JSON parser. Refer to include/yaz/json.h .
553 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
554 Used to be int in some cases. Many wrbuf_-functions used to return an int
555 indicating some length.. These return values were never used. And so they
558 ODR: odr_malloc, odr_total now takes size_t for size.
560 clone_z_type: fix leak; occurred for encoding failures.
562 --- 3.0.52 2009/12/03
564 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
565 bug was introduced in 3.0.51.
567 --- 3.0.51 2009/12/02
569 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
571 tcpip comstack: fix leak for getaddrinfo.
573 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
574 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
575 Decoding of SRU "path" database is performed by private function
576 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
577 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
579 yaz-client: honor base command for SRU. Change when database setting
580 is applied for SRU and ensure it is kept when a connection is reset.
581 Change also the way errors are displayed or SRU (decoding of packages).
583 --- 3.0.50 2009/11/02
585 Add support for extra request / response data for SRU codecs and GFS.
586 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
587 for extra data response buffer and length. For the GFS, both request
588 and response data (XML) is carried in extra_args and extra_response_data
589 for the search handler. Patch by Ko van der Sloot.
591 ZOOM: For queries that cannot be converted to the specified rpnCharset,
592 ZOOM now returns a diagnostic on the client-side ('invalid query' /
593 10010). This fixes bug #2113.
595 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
596 cmdfile included a 'quit' command that would result in a memory violation.
598 --- 3.0.49 2009/10/01
600 Make a number of functions defined in xmlquery.c static. These have
601 never been declared in a public header file (yaz/xmlquery.h) and was
602 made public by mistake.
604 Improve speed of character conversions (iconv utilities). This makes
605 conversions from MARC-8 faster.
607 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
608 unless type desired is "raw". This will prevent type "xml" from
609 returning ISO2709 .. Which obviously can not be XML parsed.
611 Fix memory leak in ZOOM that would occur if option apdulog was used
612 on a re-used connection.
614 Frontend server logs HTTP requests.
616 Frontend server now sends Z39.50 close when it times out (sesssion has
617 been idle for too long). Versions 2.0.30 and earlier also sent close.
618 But due to a mistake this was disabled in all versions after that, i.e.
619 the server would just close the socket immediately.
621 yaz-client emits a better message when receiving an unrecognised
622 userInformationField.
624 Skip zero-length subfields when decoding ISO2709. This rare case happens
625 if a record has two FS characters in a sequence. Without this patch
626 there would be a reference beyond char array in using_code_len fragments
629 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
631 --- 3.0.48 2009/08/28
633 The show command offered by the zoomsh command now takes a 3d optional
634 parameter type which is what is passed to ZOOM_record. If the type
635 argument is omitted, "render" is used.
637 RPN to CQL conv may use USE string attributes (bug #2978).
639 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
641 --- 3.0.47 2009/07/08
643 Function yaz_xml2query allows a diagnostic element in the PQF XML
644 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
645 code and additional info respectively.
647 The BER BOOLEAN is now the integral type Odr_bool which still happens
648 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
649 typedef'd to Odr_int. This is still an integral 'int', but it may be
650 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
651 ASN-1 compiler as well as programs has been updated to use the new types.
653 --- 3.0.46 2009/06/08
655 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
656 only the bibliographic record was rendered. For type=opac, an OPAC
657 record is only returned if it is present.
659 iconv: small fix for encoding of advancegreek.
661 yaz-client: avoid double display of SRU/SRW records (bug #2798).
663 yaz-client: option auto_reconnect=on really reconnects.
665 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
667 server: avoid null ptr ref for for yaz_poll errors.
669 build: fix RPM build for RHEL 5.3.
671 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
673 --- 3.0.45 2009/03/31
675 Fixed bug #2709: TCP connect returns Invalid argument.
677 Fixed compilation for mingw.
679 Honor charset for raw records (ZOOM_record_get).
681 Fixed use of errno for threaded mode that was seen on Solaris 10.
683 Fixed argument passing with blanks in value for Windows Service.
685 Disable YAZ' own log rotate by default (no 1 GB limit).
686 The variable l_max_size which specifies the log file limit is set to 0
687 (DISABLED): This is due to the fact that YAZ is most often deployed using
688 logrotate. Also YAZ can not perform log rotate because of unsufficient
689 permissions (setuid).
691 --- 3.0.44 2009/02/17
693 List supported encodings in man page for yaz-iconv.
695 Fixed missing SSL libs for --libs output
697 Re-established OID record syntax application-xml. Nobody should use it
698 but we don't want to change soname because of this symbol being absent.
700 --- 3.0.42 2009/02/02
702 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
704 Added member named_result_sets for init handler struct for the GFS. This
705 allows a server to disable named result sets.
707 Removed OID record syntax application-xml.
709 Added support for rule-based transliterator for ICU wrapper of YAZ.
711 Fixed bug #1902: yaz-icu XML output.
713 Make YAZ checks Emacs friendly.
715 BITSTRING value shows value. Bug #2346.
717 ISO2709 decoding: skip control characters from indicator data.
719 Omit sort key by default in yaz-icu's output.
721 Allow combined single char options (again) for YAZ' options function.
723 Utility yaz-marcdump got option to display YAZ version (-V).
725 Allow YAZ to use ICU 3.4.
727 Added new ICU test case which illustrates removal of diacritics.
729 --- 3.0.41 2008/12/29
731 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
733 --- 3.0.40 2008/12/29
735 For configure, using option --without-xml2 also disables Libxslt/Libexslt
738 Fixed bug #2352: yaz-marcdump crashes for certain record.
740 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
742 Added support for Danmarc2 to UTF-8 conversion.
744 Added support for ISO5426 to UTF-8 conversion.
746 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
747 implementation version.
749 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
751 --- 3.0.38 2008/11/10
753 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
754 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
756 ZOOM C now interprets databaseName option for ZOOM connection as path
759 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
761 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
763 Dummy Libxml2 types no longer defined in headers of YAZ'.
765 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
768 --- 3.0.36 2008/09/26
770 Various ODR chapter fixes.
772 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
774 Added missing source for Windows compilation, mutex.c.
776 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
778 For SRU connections in ZOOM all records up to "count" are now fetched.
780 Fixed crash in generic frontend server (and yaz-ztest) which occurred
781 in Windows due to bad error handling for Libxml2.
783 Added facility for sending arbitrary records (ASN.1 any) using
784 ZOOM C's Extended service update. Patch by Sam Reynolds.
786 New options for ZOOM C's connection, logapdu which makes ZOOM log
789 --- 3.0.34 2008/06/18
791 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
793 --- 3.0.32 2008/06/12
795 Fixed memory violation that could occur when decoding UTF-8. This bug
796 was only present in 3.0.30 of YAZ.
798 --- 3.0.30 2008/06/06
800 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
801 GNU TLS is used by default (if found).
803 yaz-ztest returns OPAC records if a client asks for OPAC.
805 Improved speed of MARC-8 encoding.
807 Added support for lossy and loss-less MARC-8 encoding.
809 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
811 Added new Windows Service wrapper (sc).
813 yaz-client's itemorder command may now send a file.
815 Fixed yaz-marcdump to allow the use of NS prefix for record element.
817 Added new function yaz_log_xml_errors.
819 Allow (but warn) unknown XML attributes in MARCXML parsing.
821 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
823 The UTF-8 to MARC-8 conversion now uses a different set of characters
824 for Greek symbols. Bug #2120.
826 --- 3.0.26 2008/02/21
828 Added yaz_daemon (daemon.h).
830 Fixed bug #2068: pkg-config trouble
832 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
834 --- 3.0.24 2008/01/28
836 Document --with-xml2 option.
838 Added OPAC XML XSD (etc/opacxml.xsd).
840 Allow glob mask for name attribute in retrieval element for the
841 generic frontend server's retrieval facility.
843 Changed yaz_poll_poll to return yaz_poll_except for all returned events
844 except POLLIN/POLLOUT.
846 Fixed error handling in cs_listen. Bug #2037.
848 --- 3.0.22 2008/01/20
850 Fixed version in yaz/yaz-version.h.
852 Fixed bug #2027: Crash when closing connection.
854 Changed configure so that ICU support is only enabled if only ICU
855 and Libxml2 is available (because the ICU chain is XML based).
857 --- 3.0.20 2008/01/15
859 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
860 is built. Only this DLL depends on the ICU runtime.
862 yaz-ziffy is no longer part of YAZ. It is distributed separately by
863 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
865 Changed license of CCL module to 'Revised BSD'. After consultation with
866 remaining members of the original EUROPAGATE consortium, we are re-issuing
867 the CCL module without a separate license. The software was developed by
868 Index Data as part of a research project. The special license was included
869 to help feed usage information back to the project consortium to support
870 project evaluation. At this time, the project consortium has long-since
871 disbanded, and the majority of the original principals have retired. At the
872 same time, we have significantly modified the software during the following
873 years, to the point where very practically no original code remains. To
874 simplify re-use of the software, we have contacted those members of the
875 consortium who could be reached, and agreed to re-issue the module as a
876 proper part of the YAZ package.
878 Tcl scripts uses /usr/bin/tclsh as preferred shell.
880 CQL closer to being version 1.2 compliant. CQL also allows free-form
881 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
884 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
885 bug could make Extended services handling crash in the ZOOM layer. This
886 bug was only present in YAZ 3.0.18.
888 --- 3.0.18 2007/12/19
890 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
893 yaz-marcdump reads and writes collection wrapped records.
895 Handle OPAC for record conversion module.
897 Fixes for ICU wrapper.
899 Allow ICU libs to be controlled with --with-icu .
901 --- 3.0.16 2007/11/12
903 Added yaz_poll which is a wrapper for select/poll. When poll is available
904 and non-buggy, it is used, by yaz_poll . This allows more than 1024
905 sockets to be in use.
907 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
908 functionality through an XML based configuration (ICU chain). This system
909 is useful for search facilities such as Pazpar2 and Zebra that needs to
910 perform tokenization of indexed material. The ICU code in a separate
911 library libyaz3_icu.a.
913 Added HTTP tunnel facility for COMSTACK, bug #1752.
914 This is a facility that allows a Web proxy, such as squid, to tunnel
915 Z39.50 traffic. This facility is "transparent" to must applications
916 using YAZ. It's enabled by using pseudo transport connect: followed by
917 the proxy address, followed by command, then follwed by he regular
918 "virtual" addresss. For example,
919 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
921 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
923 --- 3.0.14 2007/09/21
925 Fixed bad memory reference in ZOOM_record - cuased by member not being
926 initialized. This was a problem only in YAZ 3.0.12.
928 Fixed bug in conversion from MARC to XML: Non-XML characters in control
929 fields were not removed.
931 Changed the way C code is generated from codetables.xml. Made a MARC-8
932 conversion trie for each characterSet section rather than codeTable.
933 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
934 of codetables.xml from Larry Dixson, LOC. Bug #1464.
936 --- 3.0.12 2007/09/12
938 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
939 from ZOOM_record_error).
941 ZOOM C function ZOOM_record_get returns record schema for type="schema".
943 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
945 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
947 Better SRW-to-Bib-1 diagnostic mapping.
949 ZOOM C and yaz-client announces SRU version 1.2 by default.
951 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
954 Fixed in yaz_sru_decode to allow other version than 1.1.
956 --- 3.0.10 2007/08/22
958 Added support for SRU scan for ZOOM.
960 Added support for the use of the older versions or Extended Service
961 Update in ZOOM. To faciliate this, an option "updateVersion" may be
962 set to the version , 1=first, 2=second, 3=third. The third version is
963 what ZOOM C has used so far. And that, obviously, is the default.
965 Added support for CCL queries in Z39.50 queries sent to the GFS (and
966 therefore in Zebra and in SimpleServer-based applications). The new
967 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
968 qualifier file used to transform incoming CCL queries into Type-1 RPN,
969 which is passed into the back-end search callback function.
971 Added support for HTTP Basic authentication in clients: the SRU/W
972 codec encodes the username/password elements of the PDU structure
973 appropriately, and these may be set using the "user" and "password"
974 options in ZOOM-C applications (the same options that are used for
975 Z39.50 authentication).
979 Fixed bug #1208: SSL appears to be broken in ZOOM.
981 Fixed bug #1206: Libxml2 include path weirdness.
983 Added oid_name_to_dotstring.
985 Allow elementSetName to be specified for ZOOM C record update.
987 Allow waitAction to be specified for ZOOM C based for Extended Services.
989 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
990 syntax OID. Bug introduced in YAZ 3 series.
992 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
996 Fixed bug #1157: yaz-client does not read .yazclientrc from current
997 directory. yaz-client now reads commands from file given by option -f
998 if specified; then tries to read .yazclientrc in current directory.
999 Failing that, it reads .yazclientrc from user's home directory.
1001 Added support for correlationInfo Note and ID for Record Update via
1004 Added yaz-client command querycharset which specifies character set for
1005 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1006 (termListAndStartPoint).
1008 Charset ISO5428:1984 is an alias for ISO5428-1984.
1010 Implemented a way to perform scan in a result set using Z39.50. This
1011 is achieved by attaching the result set name in the characterInfo
1012 (type InternationalString) of OtherInformation in the Scan Request PDU.
1013 The result set is identified in the otherinformation by the new OID:
1014 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1015 This allows for scan in result set and faceted search . Zebra did some
1016 of this in the APT term using attribute type 8 and value being result
1017 set. Using the OtherInformation approach for this is cleaner and easier
1018 to work with in proxies and the like. This facility can be used in
1019 yaz-client using new command setscan which takes a result set as first
1020 argument, start position (APT) as second.
1022 Changed decoding of SRU XML packed records to deal with servers that
1023 have recordData with XML data with multiple root nodes. Also make
1024 comparison for recordPacking case insensitive. Again, one server
1025 returns "XML" where others return "xml".
1027 For SRU responses allow Content-Type application/xml as well as text/xml.
1029 --- 3.0.4 2007/05/21
1031 Fixed bug in character set conversion of BER strings. Bug introduced
1034 --- 3.0.2 2007/05/08
1036 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1038 For OID class, use oid_class consistently.
1040 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1043 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1044 character set for bibliographic information interchange". By Giannis Kosmas.
1046 Added documentation on new OID API.
1048 --- 3.0.0 2007/05/02
1050 Changes to generic frontend server interface: added new member
1051 'query_charset' for bend_initrequest structure. A backend init handler
1052 should set this member to its native character set for query terms.
1053 When defined, the frontend server logic will announce this character set
1054 to a client if the negotiationModel bit is set by the client. All server
1055 implementors are encouraged to specify this. If a backend server does not
1056 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1058 Added CCL utility to remove terms (stop words) from resulting RPN
1059 tree. This is handled by functions with prefix ccl_stop_words_ .
1061 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1062 terms in RPN queries.
1064 Clean-up the CCL API. Moved some internal structures from ccl.h to
1065 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1066 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1067 This is replaced by ccl_parser_find_str which takes a string instead.
1069 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1070 libyaz.la is the core of YAZ except the generic frontend server and
1071 does not depend on POSIX threads anymore. libyaz_server.la is the
1072 generic frontend server facilities and uses POSIX thread functionality
1073 if available. The libyaz.la no longer depends on POSIX threads because
1074 the number of global structures is limited. NMEM no longer re-uses blocks
1075 between threads ; it simply free's memory immediately but allocates in
1076 "large" chunks as usual. We don't expect any performance penalties
1077 because of this. The yaz_log system is still using a global log_level so
1078 caution must be taken when modifying it with yaz_log_init_.. +
1079 yaz_log_mask_str. This, however, should not cause any trouble because
1080 these functions are called during initialization of application code
1081 anyway. `yaz-config --libs server` returns libs for server applications;
1082 `yaz-config --libs` returns libs for non-server applications.
1084 New OID database - with public definitions in oid_db.h. Removed old OID
1085 database including the head oid.h and definitions such as enum oid_value
1086 and struct oident. The new OID database uses the same string names as
1087 before but the 'protocol' is gone. There are now only two representations
1088 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1089 converts from string to OID; functions with prefix yaz_oid_to_string
1090 converts the other way.
1092 Change to emit_term() in CQL-to-PQF query translation: when a term has
1093 the /regexp relation modifier, do not process it for leading and
1094 trailing "^" and "*", which have quite different meanings in regular
1097 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1098 write handlers no longer carries a 'last' parameter. This will make
1099 yaz_iconv flush "less" characters. A flush is performed by call to
1100 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1102 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1103 removed, because function yaz_query_to_wrbuf does the same.
1105 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1106 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1108 Deprecated MARC utility functions removed.
1110 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1113 Branch split: YAZ_2_1_55_branch
1115 --- 2.1.54 2007/03/16
1117 Fix to ZOOM-C so that transparent reconnection is properly handled on
1118 connections that are in asynchronous mode.
1120 Fixed compilation on OpenBSD 4.0.
1122 Large strings in GRS-1 records are now properly displayed in yaz-client.
1124 Added character conversion support for "advancegreek"; based on patch from
1127 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1128 sequence is met. Before the error was not set so it would be unknown.
1130 Adjust yaz-marcdump MARC reader so that it skips until record separator
1133 --- 2.1.52 2007/03/07
1135 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1136 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1137 fd_set structure used as a bitmask for the FDs to be selected on.
1139 Using ACX_PTHREAD macro to check for POSIX threads.
1141 Fixed have-vsnprintf check.
1143 --- 2.1.50 2007/02/23
1145 Fixes for configure on BSD. Bug #900.
1147 Added snprintf/vsnprintf wrappers for systems that don't have
1148 limits (heavens forbid).
1150 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1151 created before all previous tasks were completed and removed from the
1152 task queue, the new task could be removed by a mistake.
1154 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1156 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1158 Fixed bug #832: Problem with MARC/charset in yaz-client.
1160 Fixed bug #668: save command line history for yaz-client.
1162 Fixed bug #830: pkg-config support.
1164 --- 2.1.48 2007/01/23
1166 Extended ZOOM result set options with two options that may be read by
1167 a client: resultSetStatus and presentStatus with values as specified for
1169 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1171 Fixed bug #827: Using SSL fails on Debian etch.
1173 Fixed bug #826: Weird looking chars for set of MARC records.
1175 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1176 that is treated as an ItemOrder with itemRequest being an XML document
1177 external. The value of "doc" is the content.
1179 Extended the GFS search facility. New member of bend_search_rr
1180 'estimated_hit_count' signals that hits is known to be an estmate
1181 (higher or lower than real hit count). New member 'partial_resultset'
1182 signals that the search was partial (hit count is lower or equal than
1183 real hit count). For Z39.50, the information is stored in resultSetStatus
1184 member of SearchResponse APDU. For SRU, the information is signalled
1185 via SRU diagnostic 59: "Result set created with valid partial results
1188 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1190 --- 2.1.46 2007/01/13
1192 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1194 Added ZOOM_connection_peek_event.
1196 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1197 the following new functions:
1198 ZOOM_event_nonblock, ZOOM_connection_process,
1199 ZOOM_connection_get_{socket,mask,timeout},
1200 ZOOM_connection_fire_event_{timeout,socket}.
1201 The existing blocking event handler, ZOOM_event, is a wrapper for the
1202 + blocking ZOOM_event_sys_{poll,select}.
1204 Implemented function ccl_xml_config which parses XML version of CCL
1205 configuration (bug #798).
1207 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1209 Added timings utility (yaz/timing.h)
1211 --- 2.1.44 2007/01/03
1213 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1216 Fixed bug #779: Rotation of apdu.log fails.
1218 Fixed for character set conversions:
1219 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1220 Honor G1 set in MARC-8 decoding.
1222 --- 2.1.42 2006/12/17
1224 Fixed bug #775: char conversion does not handle Alternative UTF-8
1227 Implemented function yaz_marc_read_line which parses MARC line format
1228 records. There is a wealth of formats out there. So far, this function
1229 reads line records produced by yaz_marc_write_line.
1231 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1232 more generic and easier to remember(!) options: -i format and -o format
1233 which specifies input format and output format respectively - where
1234 format is one of "marc", "marcxml", "line", "marcxchange".
1236 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1237 does not print anything except warnings for records.
1239 For yaz-marcdump, added support for MARC split into files (-s) with a given
1242 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1243 spec, at http://www.loc.gov/standards/sru/record-update/
1244 This has changed the binary layout of the following structs:
1245 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1246 bend_update_rr . Patch by Ko van der Sloot.
1248 Added GFS utility function bend_assoc_is_alive which returns 1 if
1249 association is still alive (client is connected); 0 otherwise (client
1250 closed connection). This allows busy servers to stop working for
1253 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1254 been a separate piece of software. This version of ziffy has been modified
1255 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1257 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1259 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1260 Client code may now interrogate options such as "init_opt_sort" to
1261 find out whether the server claims to support various options.
1263 --- 2.1.40 2006/11/27
1265 Added utilities yaz_{set,get}_esn to set/get element set name from
1268 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1269 of YAZ and has been so since YAZ 2.1.10.
1271 Implemented ZOOM_record_error which returns error information for
1272 record (surrogate diagnostic).
1274 --- 2.1.38 2006/10/31
1276 Updates for SRU Update by Ko van der Sloot:
1277 1. Changed name from "operation" to "action"
1278 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1279 versions in the code, marked as 'backward compatible'.
1280 3. Added diagnostics for SRU Update.
1282 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1284 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1286 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1288 For GFS, fixed problem with SRU diagnostic 'First record position out of
1289 range' being issued for 0 hits.
1291 zoomtst10 part of Windows Build.
1293 --- 2.1.36 2006/10/13
1295 Implemented yaz_filepath_comp which splits a path into file path
1296 components (required by Zebra 2.0.3+).
1298 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1299 BSD inspired license until now so this should not have any real impact on
1300 anybody. See http://www.opensource.org/licenses/bsd-license.php
1302 Fixed bug #687: Missing log lines.
1304 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1307 Fixed bug #689: SRU diagnostics to be added.
1309 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1310 whether a connection is idle (no more work do do).
1312 --- 2.1.34 2006/10/04
1314 Change type of optval from long to int for invocation of setsockopt with
1315 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1317 Added support for specifying the max log file size for the Generic
1318 Frontend Server. The size is given with option -r.
1320 --- 2.1.32 2006/09/21
1322 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1324 --- 2.1.30 2006/09/17
1326 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1329 Fixed bug in Generic Frontend Server that could cause a server to stop
1330 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1332 For the generic frontend server, the maximum record size is used as maximum
1333 size of incoming packages (SRU + Z39.50). The value until was previously
1334 only used in Z39.50 Init negotiation and, later, in a session controlled
1335 sizes of records returned. This is controlled using -k option. It can be
1336 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1338 --- 2.1.28 2006/09/04
1340 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1343 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1345 New option for yaz-marcdump -lpos=value which allows setting a portion
1346 of MARC header to a certain value.
1348 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1350 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1351 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1353 --- 2.1.26 2006/08/15
1355 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1358 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1360 --- 2.1.24 2006/08/08
1362 Fixed MARC ISO2709 encoding routines to deal with character set
1365 Minor changes to GFS logging. Database included in search request log
1368 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1369 cached/multiple records.
1371 Shared libraries are built by default on Unix+configure.
1373 Changed cql2pqf transformation to use a different evaluation order. The
1374 new order is: always, relation, structure, position, truncation, index
1375 and relationModifier. Old order was: always, relation, relationModifier,
1376 structure, index, position, truncation. Note that the the latter ones
1377 override former ones for identical attributes.. The new scheme means that
1378 it is possible to override any existing attribute with a relationModifier.
1379 And also that it is possible to override everything for the index rule
1380 (except the ones listed in relationModifier). No order is perfect but this
1381 one, we believe, covers more real cases.. The "always" should have been
1382 called "default", since the attributes there can be overridden with all
1385 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1386 compilation phase, but also for yaz-config --cflags output. This allows
1387 us to have public headers with Libxml2 stuff in them . It should also,
1388 eventually, make Libxml2 checks redundant in packages using YAZ, such
1391 --- 2.1.22 2006/06/15
1393 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1394 stored in uri, message and details.. Previously diagnostics were stored
1395 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1396 compatibility.. but he's probably the only one affected, so.
1398 Added support for CCL, compiled on the client side, in ZOOM-C. This
1399 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1400 input; the resulting query objects can be used for for searching with
1401 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1403 YAZ' configure searches for OpenSSL by default.
1405 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1406 SL_CTX_use_certificate_file. See
1407 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1408 for more info. Thanks to Ko van der Sloot.
1410 --- 2.1.20 2006/06/02
1412 Bug #600: SRU GET, POST support for yaz-client. Introduced
1413 command 'sru' which selects method SOAP/GET/POST.
1415 Allow missingValueAction to be specified for the sortspec string -
1416 function yaz_sort_spec. By default, the missing value action is null.
1417 Use ! to specify "abort". Use = followed by stringvalue to specify default
1420 Ensured that Present-handler (if defined) is called in GFS before any call to
1421 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1422 searchRetrieve requests.
1424 Documentation for YAZ is now based on the Docbook XML/XSLT using
1425 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1426 is no longer depending on jade/openjade or docbook-to-man scripts.
1427 PDF is no longer part of the distribution - but can optionally be
1428 made using DSSSL/jadetex or FOP.
1430 Added retrieval handling support in Generic Frontend Server to support
1431 conversion between MARC/XML as well as XSLTtransforms. See
1432 etc/yazgfs.xml for an example.
1434 Added Authentication support to Generic Frontend Server in SRU
1435 mode. Authentication using HTTP Basic is supported, as is the use
1436 of 'x-username' and 'x-password' parameters in the request itself.
1438 Added support for a new character set MARC8s identical to MARC8 except
1439 that it converts combined characters to single Unicode characters in the
1440 Latin-1 range (when possible).
1442 --- 2.1.18 2006/04/24
1444 ASN.1 compiler 0.4: generates brief Doxygen file header for
1445 generated .h/.c files.
1447 Utility yaz_iconv now supports conversion to MARC-8.
1449 New facilities for the MARC module. The reading - and writing of
1450 content are separate methods for the yaz_marc_t handle. The following
1451 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1452 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1453 format). Write functions have prefix yaz_marc_write_.. The existing
1454 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1455 available. Removed support for OAI-MARC and simplexml (not the
1456 simplexml from PHP5).
1458 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1459 to be returned for this connection.
1461 --- 2.1.16 2006/03/31
1463 Allow multiple languages and charsets to be specified with
1464 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1465 negcharset iso-8859-1,utf-8
1467 Translation of proximity nodes from CQL into PQF now works.
1469 Moved to automake 1.8, 1.9.
1471 Added function yaz_log_set_handler which allows a log handler to be
1472 installed. This handler will be called for all log messages. Output
1473 to file is also produced; but that can be disabled by passing NULL
1474 fname to yaz_log_init_file.
1476 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1478 For SRW (including GFS), accept application/soap+xml as content-type
1481 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1482 produces NO stylesheet reference even if a default stylesheet is specified
1485 --- 2.1.14 2006/03/14
1487 Updated Windows package to include yazd.dll + yazd.lib for the
1488 Development component.
1490 If the environment variable YAZ_LOG is set, then it is used as a
1491 string indicating the default level of logging to use if not
1492 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1493 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1494 used as before. So, for example, to omit warnings from YAZ logging,
1495 export YAZ_LOG=-warn
1497 cql_transform() now map structure and other attributes before indexes,
1498 so that index-specific structures and other attributes can override
1499 defaults. So now a combination of mapping specifications such as:
1501 index.dc.date = 1=date-modified 4=5
1502 does the right thing.
1504 cql_transform() now also respects the "always" mapping specification,
1505 which establishes an initial set of attributes to be used for all
1506 terms except where overridden by more specific attributes associated
1507 with the index, relation or modifier.
1509 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1510 which mode to use; one of "post", "get" or "soap" (SRW, default).
1512 Fixes for yaz_iconv routines: changed trie-based character set conversions
1513 to use only non-negative values for bit fields due to Sun's C compiler not
1514 supporting negative values.
1516 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1517 sequences where not read correctly. Fix by Rustam Usmanov.
1519 Updated win/makefile to use options, settings which makes things
1520 compile with VS C 2005.
1522 --- 2.1.12 2006/02/01
1524 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1526 In ZOOM socket code, use select instead of poll on MacOSX.
1528 ZOOM-C now support client-side compilation of CQL into RPN that is
1529 sent to the server, enabling CQL to be used against all Z39.50
1530 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1531 ZOOM_query object, and submit it using ZOOM_connection_search().
1532 The CQL-to-RPN translation uses a configuration file, the name of
1533 which must be specified in the Connection's "cqlfile" option.
1535 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1536 function, which takes as its start-term parameter a ZOOM_query object
1537 (which may have had either CQL or RPN set into it).
1540 --- 2.1.10 2005/11/29
1542 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1543 GFS to support this as well. Backend handler, bend_srw_update, does the
1544 update work. Code contributed by Ko van der Sloot.
1546 Allow retrieval of Search Result-1 information in ZOOM by the use of
1547 options that are attached to a result set. ZOOM documentation updated
1550 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1551 UTF-8 conversion. Patch by Raj Patel.
1553 Added option -m to GFS to control formatting of timestamps in log file.
1555 Added 'exit' as synonym for 'quit' in yaz-client
1557 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1558 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1559 for the new members. Patch by Ko van der Sloot.
1561 Added support for SRU POST. It is supported for content-type
1562 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1564 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1565 Instead make the library libyaz.la multi-threaded. Threading as a whole
1566 can still be disabled by configure option --disable-threads. Previosly,
1567 with older GLIBCs there were problems with MT libs under Apache. This
1568 has now been fixed a long time ago.
1570 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1573 CQL module modified to be case insensitive for relations/indexes/operations.
1575 Fixed bug in CQL transform code: incorrect value relationModifieder
1578 Added 'show all' command for yaz-client which retrieves all results
1581 Added new yaz-client, xmles, which takes a (private) OID and
1582 a document to be sent as an extended service request.
1584 Describe new yaz-client commands wait_response and set_auto_wait.
1586 Increase TCP/IP listener backlog from 3 (which I am guessing was
1587 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1588 that the socket will queue as many incoming connections as it's able
1589 to handle ongoing connections. In other words, it will never now
1590 refuse a connection that it would be able to handle merely because
1591 it's not got around to accepting() enough of the pending connections
1592 yet. This is the behaviour anyway under Linux, where the listen()
1593 argument is ignored; but not under BSD and on systems such as
1594 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1595 YAZ-based servers should now be uniform across operating systems in
1598 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1599 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1600 This allows yaz-marcdump to read large MARC batches (>2 GB).
1602 Modified all YAZ source files - except the source which is auto-generated
1603 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1606 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1607 corresponding to the existing *_setl() function. These allow option
1608 values containing arbitrary valuues.
1610 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1611 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1612 except that it returns an indicator of whether or not the sort
1613 criterion was accepted (0 for OK, -1 for invalid).
1615 --- 2.1.8 2005/06/07
1617 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1618 MARC output rather than returning "new" buffer.
1620 yaz-client warns about unknown init options.
1622 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1624 --- 2.1.6 2005/05/24
1626 Added support for SRW sort in Generic Frontend Server. Patch
1627 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1628 sortKeys - or NULL if none is provided.
1630 Fixed bug #307: It was impossible to specify indefinite/no timeout
1631 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1634 Added support for multiple languages and charsets to be specified in
1635 ZOOM. Each charset/language is separated by a blank. If negotiation is
1636 in effect in init-response, Option
1637 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1638 Code based on patch by Vasiliy Osadchuk.
1640 Fixed bug #306: infinite recursion that occurred when calling
1641 yaz_log_level_init as the first call (before other log level or
1644 Fixed bug in scan handling in front end server: if preferred-Position-In-
1645 Response was non-present, a NULL pointer referece was performed.
1647 --- 2.1.4 2005/04/26
1649 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1650 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1651 now defined for all those error codes. So instead of putting 109 in
1652 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1653 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1655 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1658 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1660 Program yaz-client now exits and produces an error message if multiple
1661 Z39.50 servers are specified on the command line (none or one allowed
1664 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1667 --- 2.1.2 2005/03/16
1669 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1671 Fixed bug #272: Preserve spacing for CCL terms.
1673 --- 2.1.0 2005/03/14
1675 Added support for virtual hosts and multiple backend servers for
1676 the YAZ frontend server. The configution is XML based and
1677 support specificition of CQL to RPN mappings and explain information.
1678 See section "Virtual Hosts" in the YAZ manual.
1680 Extended OPAC display utility. OPAC display utility renders
1681 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1682 to supplement yaz_marc_decode_wrbuf.
1684 Fixed a bug in MARC decoder that could caused it to crash for some
1685 invalid MARC records. More diagnostics and warnings where added in
1686 XML output (warnings, etc are stored in comments).
1688 --- 2.0.34 2005/02/08
1690 Fixes for UNIX domain sockets. Bug #261.
1692 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1694 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1695 Added yaz_marc_subfield_str which defines subfield lead string which is
1696 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1697 yaz_marc_endline_str which defines end of fields string used in
1698 YAZ_MARC_LINE format. Default string is newline.
1700 Experimental support for MarcXChange. This format can be produced
1701 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1702 http://www.bs.dk/standards/MarcXchange.xsd
1704 Added yaz-client commands scansize that sets maximum number of
1705 entries to be returned by scan.
1707 --- 2.0.32 2005/01/11
1709 Added support for SRW scan in yaz-client and Generic Frontend Server.
1711 * Added whereInList member to SRW Scan Term.
1713 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1715 Fixed NMEM system to return aligned blocks on the smallest boundaries
1716 that are suitably aligned for all possible types on the particular
1717 architecture YAZ is being built for.
1719 --- 2.0.30 2005/01/04
1721 Fixed numerious warnings that was issued with newer versions of GCC.
1723 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1724 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1727 Make YAZ Generic Frontend Server slightly faster.
1729 Enhance (and reduce) logging for Generic Frontend Server.
1731 Revert YAZ log system so that it flushes every write operation
1732 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1734 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1735 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1736 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1737 will effectively disable old definitions.
1739 --- 2.0.28 2004/11/09
1741 Added yaz_log_time_format which specifies log format using
1744 Added yaz_log_module_level which returns mask for a module. Value
1745 is non-zero mask a if module is enabled; zero if disabled.
1747 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1748 in include/yaz/cql.h.
1750 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1752 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1754 Fixed bug #172: RPM builds does not enable SSL.
1756 Doxyfile.in part of dist. Doxyfile generated by configure.
1758 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1759 are given and the corresponding component does not exist.
1761 Extend CCL documentation in YAZ reference. Describe r=r.
1763 --- 2.0.26 2004/10/01
1765 Fixed MARC->MARCXML conversion to properly deal with
1766 fields, subfields, indicators having non-ASCII characters.
1768 Fixed MARC->MARCXML conversion so that ASCII control characters
1769 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1772 Added YAZ GFS support for conversion from Z39.50 surrogate
1773 diagnostics to SRW surrogate diagnostics.
1775 Bug fix: YAZ GFS did not return schema in explainResponse.
1777 --- 2.0.25 2004/09/30
1779 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1780 now converts recordSchema to elementSetName as well as schema URI.
1782 Fixed bug in COMSTACK that prevented HTTP request packages from being
1785 --- 2.0.24 2004/09/29
1787 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1788 does not require white-space before and after the dash in a range, e.g.
1789 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1792 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1793 due to new GCC removing "redundant" code.
1795 Added yaz-client commands scanpos and scanstep that sets preferred
1796 position and step-size for scan.
1798 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1800 Added CCL utility ccl_qual_buf which parses one or more CCL
1801 spec lines in a buffer.
1803 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1804 of name and value - ignoring empty lines and comments.
1806 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1808 Added odr_get_element_path which returns current element path for an
1809 ODR handle. This utility is useful in error handling or user-defined
1812 Added ODR_PRINT utility odr_set_stream which is is a more generic
1813 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1814 to a write function and pointer to close function. The close function - if
1815 non-NULL - will be called during odr_destroy.
1817 Fixed bug in CCL parser where truncation char was not removed from
1818 right side when truncation=both was in effect.
1820 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1823 --- 2.0.23 2004/08/11
1825 Fix buffer overrun in CQL parser when dealing with proximity (%).
1827 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1828 to UTF-8/UCS conversion is now only based on codetables.xml.
1830 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1832 --- 2.0.22 2004/08/06
1834 Add support for more "commit changes" in ZOOM (uses Extended Services).
1836 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1839 Yet another small fix for configure of SSL.
1841 --- 2.0.21 2004/05/14
1843 Fix SSL libs for configure when --with-openssl=DIR is given.
1845 --- 2.0.20 2004/05/10
1847 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1849 SSL comstack now uses yaz.pem certificate file on server side
1850 by default. Certificate filename can be configured by calling
1851 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1853 Fix bug regarding multiple calls to ZOOM_connection_connect.
1855 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1857 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1858 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1860 ZOOM now allows inspection of X509 peer certificate for verification.
1861 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1863 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1864 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1865 as "modular" but it simplifies things.
1867 Added cs_get_peer_certificate to that returns peer X509 PEM.
1869 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1870 NULL if SSL is unavailable.
1872 Documentation about MARC decoding tools.
1874 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1876 --- 2.0.19 2004/03/30
1878 Rename CHANGELOG to NEWS to follow GNU style packing.
1880 Fix bug with missing initialization of member in init_diagnostics.
1881 This bug affects threaded version of GFS server.
1883 --- 2.0.18 2004/03/20
1885 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1888 Ensure zlib.dll is packed with Windows install.
1890 --- 2.0.17 2004/03/17
1892 Fix encoding of xsd:string to use text instead of CDATA.
1894 Fix endless loop in CQL parser with unbalanced ".
1896 Use a more compact way to store MARC-8 conversion tables.
1898 --- 2.0.16 2004/03/16 Debian only
1900 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1903 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1908 --- 2.0.15 2004/03/01
1910 Another fix for decoding of XML packed records.
1912 --- 2.0.14 2004/02/25
1914 Fixes for Chunked encoding. White space not ignored after length spec.
1916 Update NS and use default NS for SRW diagnostic elements.
1918 --- 2.0.13 2004/02/23
1920 Implement ZOOM_resultset_cache_reset which resets record cache.
1922 Implement ZOOM_resultset_sort which sorts a result set.
1924 Implement chunked HTTP transfer.
1926 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1928 --- 2.0.12 2004/02/16
1930 Added member 'schema' to bend_explain_rr structure so that backend
1931 can specify explain record identifier. Defaults to Zeerex 2.0.
1933 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1935 --- 2.0.11 2004/02/16
1937 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1940 Added init command for yaz-client which sends "extra" init request.
1942 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1943 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1945 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1947 Make ZOOM error code for "invalid query".
1949 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1951 --- 2.0.10 2004/02/05
1953 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1956 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1958 Added option -p <file> to make Generic Frontend Server to write PID file.
1960 Added option -D to put Generic Frontend Server in background on its own.
1962 Make ZOOM C recognize option "password". If unset, "pass" is used
1963 (for backwards compatibility).
1965 Fixed a bug in Generic Frontend Server that could make it crash if a
1966 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1969 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1970 Must be issued before open, in order to be in effect.
1972 --- 2.0.9-6 2004/01/12 Debian/Windows
1974 Make the SRU server more picky WRT unknown params, etc.
1976 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1978 New YAZ client command, options, that sets Z39.50 options.
1980 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1981 options from a string of tokens (one token for each option bit).
1983 Update SRW diagnostic code messages.
1985 --- 2.0.9-5 2004/01/07 Debian/Windows
1987 Handle user defined stylesheet for SRW/SRU.
1989 --- 2.0.9-4 2004/01/06 Debian/Windows
1991 Fix bug in decoding of Content-Length.
1993 --- 2.0.9-3 2004/01/06 Debian/Windows
1995 Fix a bug with decoding of XML packed records.
1997 --- 2.0.9-2 2004/01/05 Debian only
1999 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2001 Fix bug in SRW/SRU diagnostics decoding.
2003 --- 2.0.9 2004/01/05
2005 Fixed bug in Generic Frontend Server which could drop records exceeding
2006 preferred message size. Reported and fixed by Irina Dijour.
2008 Fixed calculation of package size for structured records in Generic
2009 Frontend Server. Reported and fixed by Irina Dijour.
2011 Fixed namespace for SRW/SRU diagnostics.
2013 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2015 --- 2.0.8 2003/12/22
2017 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2018 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2021 CQL changes to reflect recent changes to the specification:
2022 * Documentation talks about context sets instead of index sets.
2023 * Documentation talks about indexes instead of qualifiers.
2024 * The CQL-to-PQF transformer's configuration file now uses
2025 "index.set.name = <attributes>" instead of the old form
2026 "qualifier.set.name = <attributes>". (Both forms are still
2027 understood but the latter is deprecated.)
2028 * CQL terms with no explicit index specified are now interpreted as
2029 cql.serverChoice instead of srw.serverChoice (which of course
2030 behaves exactly the same.)
2032 --- 2.0.7 2003/12/16
2034 MARC conversion can now generate ISO2709 output in another
2035 character set. yaz-marcdump uses this facility if you invoke it
2038 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2039 functions from there can be used from C++.
2041 --- 2.0.6 2003/12/04
2043 Frontend server now transfers memory from decoded packages to stream
2046 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2047 references to show up.
2049 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2050 the ZOOM Abstract API. The older names for the same options are still
2051 also supported for the benefit of old applications.
2053 ZOOM-C supports "implementationId" and "implementationVersion" options
2054 to go along with "implementationName". These allow the user code to
2055 specify identification strings to be sent to servers.
2056 Add OID for the new ExtLite attribute set.
2058 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2059 as requested/supplid by Ere Maijala <ere@atp.fi>
2061 For generic frontend server, reverse the order of
2062 "toolkit-supplied / application-supplied" strings sent as implementationId,
2063 Name and Version. Also, remove the spaces around the slash. This brings
2064 the GFS in line with the behaviour of ZOOM-C on the client side.
2066 Add function ZOOM_scanset_display_term.
2068 yaz-client shows scan displayTerm if present.
2070 Utility yaz-iconv is now installed by default along with the man page
2073 Extend configure check for OpenSSL to use pkg-config where available (such
2076 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2077 server to specify uid/gid/mask for socket using the format
2078 unix:[user=uid,][group=gid,][umask=mask,]file=path
2079 If file= is omitted the existing format is assumed, e.g.
2081 in which case the mask is 0666 (rw for everybody).
2083 Major restructure of YAZ source. All source in libyaz is in src directory.
2084 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2085 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2087 Added man page for utility yaz-marcdump (used to be called marcdump).
2088 yaz-marcdump is installed by 'make install'.
2090 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2091 of incoming package failed.
2093 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2095 Change prototype of odr_perror: add const to message string.
2097 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2099 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2100 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2101 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2102 DNS lookup. There should not be any compatibility problems with this
2103 assuming that blocking=1 or 0 is used.
2105 Fix bad reference in UNIX comstack in function cs_addrstr.
2107 Fix for compilation on AIX.
2109 The generic front-end server (server/seshigh.c) now supports returning
2110 Init diagnostics to the client in User-information-field, in
2111 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2114 --- 2.0.4 2003/09/04
2116 Allow any CQL relation (not just all,any,exact,scr).
2118 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2119 that features the same UI.
2121 Implemented command update0 in YAZ client which is equivalent to
2122 update but uses old of Ext Update ASN.1.
2124 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2125 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2126 Previously no OID was used for this info.
2128 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2129 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2130 returns 'malformed search term' otherwise.
2132 SortResponse member resultCount now set to NULL in sort handler of
2135 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2138 Add three new utility functions for translating OIDs between various
2139 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2140 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2141 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2142 char *oid_to_dotstring(const int *oid, char *oidbuf);
2143 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2145 Reverted modifications for ES Update definition for z_IU0Update
2146 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2147 is back to YAZ 2.0.2.
2149 String value attributes for CCL parser.
2151 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2152 which their FirstSearch server returns in Init responses, sometimes
2153 carrying useful diagnostic information when Init fails. This has the
2154 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2155 "z39.50/oclcui.asn", where its definition is somewhat different from
2156 what OCLC document on their web-site, as required to interoperate with
2159 Support for anonymous authentication in yaz-client. Use the command
2162 * Fix the OID of the Index Data-local "admin" Extended Service from
2163 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2164 the 1000, which indicates a locally-defined OID, was a mistake.
2166 --- 2.0.3 2003/06/20
2168 Fix CCL directive @case handling so that it affects string match for
2169 both CCL keywords and qualifiers.
2171 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2172 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2173 Decoder has been updated with ASN.1 changes as listed in
2174 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2175 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2176 z_IUUpdate, remains unchanged.
2178 ZOOM_record_get may now return a record in a specific character set.
2179 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2180 "from" is the character set of record as returned by target. "to" is
2181 the character set to be returned. If omitted, "to" is UTF-8.
2183 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2185 New ODR utility, odr_getelement, which returns name of element for
2186 which encoding/decoding failed.
2188 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2189 in cases where a required element was omitted.
2191 Bug fix: some MARC8 sequences were not converted.
2193 New ZOOM option "step" which specifies number of records to be
2194 retrieved in one chunk. Used in conjunction with "start" and "count".
2196 SRW support for yaz-client. Use scheme http: to use it, e.g.
2199 yaz-client no longer does (un)intelligent character set conversions
2200 by default. Can be enabled with charset and marc_charset commands.
2202 xmalloc trace fix for 64-bit systems such as DEC alpha.
2204 Solaris 2.6 compile fix.
2206 New function, cql_strerror() translates SRW error codes, as returned
2207 by cql_transform_error(), into human-readable English strings. Used
2208 in yaz-client diagnostics when appropriate.
2210 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2211 converts it into a type-1 query which is sent to the server. This
2212 makes CQL available for use with all Z-servers, as opposed to the tiny
2213 minority that can handle CQL queries themselves.
2215 --- 2.0.2 2003/04/28
2217 New Debian package layout similar to the Redhat Package layout.
2219 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2220 and search result respectively.
2222 --- 2.0.1 2003/04/25
2224 Redhat package is now several packages: libyaz (runtime libraries),
2225 libyaz-devel (development and documentation, and yaz (utility programs).
2226 Package spec file by Morten Bogeskov.
2228 New member 'schema' in struct bend_fetch_rr which the name of requested
2229 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2230 handler MAY set this to reflect the schema of the returned record.
2232 New member 'display_term' in struct scan_entry. GFS now sets member entries
2233 and allocates scan entries to be filled by user scan handler. In previous
2234 version, entries member was allocated by the scan handler. That still works,
2235 but the GFS will ignore member display_term - assuming it was NOT set by
2236 the handler. The fact that the GFS now allocates the entries both allows
2237 for new members and makes a scan handler easier to write.
2239 Fix CQL lex buffer overflow.
2241 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2242 SRU default recordPacking is string.
2244 SRU protocol support for frontend server.
2246 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2248 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2250 Added scan for the ZOOM shell (zoomsh).
2254 * String Identifers for Schemas (Amendment 5).
2255 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2256 Old definition for schema
2257 Odr_oid *schema; /* OPT */
2262 Z_InternationalString *uri;
2263 #define Z_Schema_oid 1
2264 #define Z_Schema_uri 2
2267 * resultCount parameter to Sort Response (Amendment 1).
2268 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2270 Support for SRW 1.0 over HTTP. This is an optional feature and
2271 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2274 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2275 on the same port. SRW SearchRetrieveRequests are mapped
2276 to bend_init,bend_search,bend_fetch,bend_close.
2278 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2280 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2281 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2283 ZOOM connections are SRW based if schem http is used for hostname
2284 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2285 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2287 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2288 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2289 distance=n, order=true/false, relation=le, prox unit=word. If
2290 n is omitted, distance 1 is used.
2292 Fixed problem with C compiler include path in wrong order.
2294 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2295 on Solaris. Patch from Ko van der Sloot.
2297 New MARC decode API. All new functions operate on a yaz_marc_t
2298 handle. The most important new functions are: yaz_marc_create,
2299 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2300 decode and destroy respectively. Decoder can produce formats
2301 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2302 include/yaz/marcdisp.h.
2304 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2305 to UTF-8, UCS-32, wchar_t or Latin-1.
2307 * Prototypes for yaz_iconv_-functions moved to separate header
2308 include/yaz/yaz-iconv.h.
2310 Make a few private functions 'static' in unix.c. This prevents
2311 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2313 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2314 are set when Init Response is received.
2316 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2317 but returns diagnostic set as well.
2319 New function yaz_strerror which is a portable wrapper for
2320 strerror/strerror_r/GetLastMessage.
2322 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2323 is returned for MARC. If type is "oai", then OAI MARC is returned.
2325 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2328 --- 1.9.2 2002/11/26
2330 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2332 Fix bad race conditions on SIGTERM and terminate gracefully in
2335 Move retrieval (data1) module to Zebra since nobody seems to be
2338 Add GRS-1 render for ZOOM using same format as yaz-client.
2340 --- 1.9.1 2002/10/05
2342 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2344 Fix broken ESpec handling in data1 module.
2346 SGML reader parses comments and makes them part of the data1 tree.
2348 Added several type casts so that YAZ compiles as C++ code.
2350 ZOOM didn't handle PDU encoding failures properly.
2352 Added more Bib-1 diagnostics (approved extensions).
2354 GNU configure: better check for iconv.
2356 More portable use of accept, getpeername. Check for socklen_t. Use
2357 int/size_t if socklen_t is not defined.
2361 PQF parser rejects bad queries - including those with extra
2362 characters in them. PQF parser used to silently ignore that.
2363 Cleaner API for PQF added, which allows you to get detailed
2364 error information for bad queries (see yaz/pquery.h).
2366 Fixed bug in ZOOM_record_get for type "database".
2368 Implemented mini iconv library supporting conversions between
2369 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2371 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2373 --- 1.8.9 2002/08/20
2375 Fixed ZOOM C record cache so that preferredRecordSyntax and
2376 elementSetName is used to check for already fetched records.
2378 --- 1.8.8 2002/08/02
2380 Added three members in bend_initrequest structure to facilitate
2381 character set negotiation.
2383 Fixed a bug in frontend server that could cause indefinite
2384 loops under rare conditions.
2386 Revised character set utilities (charneg.h) so that encoding
2387 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2389 For PQF, directive @term <type> sets term type for Scan/Search.
2390 Here <type> is general, string, numeric, null. The term type
2391 is inherited - just like @attr.
2393 New call odr_set_charset that sets character set conversion for
2394 international-strings on a ODR stream. Prototype is:
2395 int odr_set_charset(ODR o, const char *to, const char *from);
2396 The InternationalString is still represented as C string in YAZ
2397 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2398 won't). On the protocol level, you can use any encoding.
2400 Support for UNIX sockets in ZOOM.
2402 Solaris recv sometimes returns errno == ENOENT. It is treated as
2403 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2405 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2406 both client and server. Code by Morten Bogeskov.
2408 --- 1.8.7 2002/05/22
2410 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2411 that they can be used directly from Visual Basic. You must recompile
2412 your windows APP if you're using ZOOM.
2414 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2415 Commands "lang" and "charset" sets language and character set respectively.
2416 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2417 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2419 Attributes from multiple CCL fields may be OR'ed rather than merged
2420 using directive "@field or". Fields are still merged by default -
2421 equivalent to "@field merge".
2423 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2426 Fixed bug in zget for parameter ExtendedServicesResponse.
2430 --- 1.8.6 2002/03/25
2432 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2434 Client displays USR.1:SearchResult-1 (hits per term).
2436 Additional Search Info for search in Generic Frontend Server.
2438 Fixed CCL parsing of "field=s".
2440 WIN32 installer - using the excellent NSIS software from nullsoft.
2442 Fixed CCL parsing of "field = - <number>".
2444 Added function yaz_marc_decode that decodes MARC for line mode
2445 display or XML (similar to that used by JZKit).
2447 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2448 Z39.50. But ISO/ILL was, however.
2450 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2451 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2453 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2454 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2456 --- 1.8.5 2002/02/03
2458 New YAZ client features: Command completion and new commands:
2459 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2460 Code provided by Jacob Poulsen.
2462 New call oid_trav, that visits all registered OIDs via callback.
2464 Function ZOOM_record_get now returns const char pointer rather than
2465 void pointer. It saves a lot of type casts.
2467 For YAZ client, command "auth" now allows you to set authentication
2468 in IdPass style. It is enabled when three tokens are given - order
2469 is user, group and password.
2471 Fix memory leaks in MARC record handling for ZOOM.
2473 New option for YAZ client, -k <kilobytes> that sets
2474 maximum record size. Similar to -k option for generic frontend
2475 server and yaz-ztest.
2477 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2479 Prefix query parser reports "fail" when bad attribute set is given.
2481 Fix in MARC decoder. Proximity logging. Fix for attribute set
2482 in scan handler for server. Patches by Shigeru Ishida.
2484 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2487 Configure option --with-openssl=<dir> now works when a directory is
2488 specified. Patch provided by Morten Bogeskov.
2490 New option for YAZ client, -u <auth>, that sets authentication.
2492 ZOOM fix: error information was sometimes "missing", since error
2493 was cleared/reset too when it shouldn't.
2495 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2497 --- 1.8.4 2002/01/04
2499 Scan for ZOOM API. New object ZOOM_scanset. New functions
2500 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2501 ZOOM_scanset_destroy.
2503 New ZOOM function, ZOOM_connection_last_event, that returns type
2504 of last event (such as "receive data", "send data", "apdu received",
2507 New ZOOM option, schema, that specifies schema for retrieval.
2509 New CCL feature. Qualifiers can be aliases for one or more
2510 other qualifiers (if more than one is given, OR is used).
2512 ZOOM uses named result sets if target supports it.
2514 Two new YAZ client commands: . (dot, which sources a script of YAZ
2515 client commands), and ! (to execute shell command.). Implemented
2518 Working on Debian packages.
2520 --- 1.8.3 2001/11/19
2522 YAZ client enables named result sets only if target supports it.
2524 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2526 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2527 with key="host" to get same result.
2529 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2530 Function Z3950_resultset_record(s) returns references to records
2531 "owned" by resultset. To become owner use Z3950_record_clone.
2533 Function z_ext_record handles Extended Services. Thanks to
2536 --- 1.8.2 2001/11/12
2538 CCL Parser fix: ignore token comma when dealing with and-lists.
2540 Documentation updates for COMSTACK.
2542 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2543 Changed prototype Z3950_records. For some functions, int parameters
2544 were changed to size_t.
2546 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2549 New MARC decode/display function, marc_display_exl, which properly rejects
2550 non-ISO2709 records. YAZ client uses it.
2552 --- 1.8.1 2001/10/29
2554 Fix bug: local attribute set wasn't set correctly in PQF strings.
2558 * Old Z39.50 codecs no longer supported.
2560 Added ZOOM C binding. See http://zoom.z3950.org/
2562 Renamed states for COMSTACKs to avoid confusion with events.
2564 Implemented cs_look and proper cs_rcvconnect.
2566 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2568 Configure detects POSIX threads on OpenBSD.
2570 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2571 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2573 When error is returned from present handler, non-surrogate diagnostic
2574 is returned in present response (and fetch handler is no longer called).
2576 * Minor adjustments to pquery parser (PQF). Token characters may be
2577 escaped by using backslash (C-style).
2579 PQF parser allows string attribute values to be specified. For @attr,
2580 non-numeric characters after the equal-sign are treated as strings
2581 (e.g. @attr 9=title).
2583 CCL trunction character may be defined (@truncation in file)
2585 * function zget_ExtendedServicesRequest sets waitAction to
2586 waitIfPossible (was wait).
2588 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2591 CCL operator names may be set in field definition files (CCL_bibset).
2592 See ccl/bib1 for an example.
2594 Fixes in ASN.1 compiler for C++ compatibility.
2596 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2597 and "op_or" to avoid conflict with C++.
2599 Fixed problem with GNU readline detection on Redhat 7.0.
2601 Added step-size for Scan backend handler.
2603 Fixed bug that made the frontend server crash when no attribute
2604 set was specified for scan.
2606 Front-end server automatically switches to original working directory
2607 when installed as an NT service. Previously -w had to be specified to
2610 Added extended attributes for retrieval module (data1), so that data1
2611 records carry d1_readXML/SGML attributes. d1_read also supports
2612 null-data rules ( <tag/>)
2614 On UNIX when POSIX threads are available, a separate library libyazthread
2615 is created. Programmers should link with that library and the yaz library
2616 when using threads. The reason for the split was that some applications
2617 on Linux, such as Apache, doesn't work well when using shared objects that
2620 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2621 (or any frontend server) in SSL mode by specifying ssl: followed by
2622 address. Only tested on UNIX.
2624 Added feature for CCL module. Virtual structure s=al or s=ol generates
2625 and-list and or-list respectively instead of phrase search.
2629 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2630 log_mask_str. This was done to avoid name conflicts with other libraries
2631 (such as other PHP extensions).
2633 Added raw OID member for preferred record syntax (request_format_raw)
2634 and returned record syntax (output_format_raw) for backend fetch method.
2636 Config file yaz-config now accepts options so that it returns specific
2637 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2639 Shared library support for UNIX using GNU libtool.
2641 * Modified backend interface. Request/Response struct's replaced by
2642 one read/write C struct. For example bend_fetchrequest and
2643 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2644 Every handler - even search has to be registered in bend_init
2645 handler. This means that the YAZ library no longer refers to
2646 external functions and it makes it possible to make the whole
2647 thing a single DLL/SO.
2649 Added Segment handler for backend server.
2651 Added Zmbol/Zebra administrative functions to YAZ client.
2653 Threaded frontend server on UNIX (when POSIX Threads are available).
2654 Starting the server with option -T enables multi-threading.
2658 Added configure option --enable-comp/disable-comp to control use
2659 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2660 located in sub directory asn.
2662 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2663 in ${exec_prefix}/bin along with the other programs yaz-client and
2666 GNU automake used to maintain makefiles.
2668 Added several OID's.
2670 Changed retrieval module so that we can load records with no abstract
2671 syntax defined. Tagpaths in these records are fully composed of string
2674 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2678 On UNIX, the generated makefile now supports a proper 'make install'.
2679 The prefix can be set via GNU configure to set the install location
2680 (default is /usr/local).
2682 * YAZ programs client and ztest were renamed to yaz-client and
2683 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2684 locations, such as /usr/bin,/usr/local/bin,etc.
2686 * YAZ Header files were moved from include to include/yaz. YAZ Header
2687 files are referred to as include <yaz/log.h> rather than <log.h>.
2688 The YAZ include path (-I ..) is therefore the same as before. Programmers
2689 should update their #include statements or use -Ipath/include/yaz
2690 instead. The main motivation for doing this change is that YAZ header files
2691 can be installed in "standard" locations /usr/include,/usr/local/include
2692 without introducing conflicts, since ALL YAZ header files are stored
2693 in subdirectory yaz (under /usr/include for example).
2695 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2696 rather than project/workspace files. We switched because project files
2697 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2700 Changed name of logging function, logf, to yaz_log, to prevent name
2701 clash with some math-log functions. The YAZ header log.h defines logf
2702 to yaz_log (#define) so there should be no incompatibilities by this
2705 Added bend_start/bend_stop handlers for server. These handler are
2706 called on start/stop of server. For windows they are called whenever
2707 a service is started/stopped.
2709 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2710 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2711 in util/yc.tcl. The auto-generated C code structures are, in a few
2712 cases, incompatible with the old decoders. There are differences in the
2713 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2714 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2715 The preprocessor variable ASN_COMPILED is defined when the compiled
2716 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2717 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2718 wish to use the old encoders/decoders you can specify --disable-yc
2721 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2722 version so that it supports both new - and old version of DB Update
2724 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2725 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2726 change. The name parameter can be set to 0 in which no name is specified
2727 for the construction. The macros odr_implicit and odr_explicit sets name
2728 parameter to zero for the construction involved. New macros
2729 odr_implicit_tag and odr_explicit_tag are similar to the others,
2730 except that a name parameter is added. For programmers' that don't use
2731 ODR they probably only need to change the call to z_APDU and z_External.
2733 Added access control facility by interfacing the TCP wrapper library.
2734 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2735 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2736 name of the daemon and enables the access control as specified in
2737 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2739 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2740 den Dool <H.M.vdnDool@kub.nl>.
2742 Added reference ID parameter to most functions in server API - refer
2743 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2745 Changed name of ccl library to libccl.a (was ccl.a).
2747 Fixed bug in decoder for Explain (Category TargetInfo).
2749 Added support for GNU readline in client. Thanks to Jacob Poulsen
2750 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2752 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2753 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2754 IMPLEMENTATION! This change was made to the development version before
2755 the ZIG decided to retract the amendment. If any users MUST be
2756 compatible with the original Update definition, PLEASE CONTACT US, and
2757 we will include a separate definition corresponding to the old Update
2758 ES. Note that because of the change to the ASN.1 of the
2759 TaskPackageRecordStructure we cannot define a single structure that
2760 will support both versions.
2762 * Added const modifier to buffer parameter for some ODR/BER encoding
2763 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2764 completeWAIS, odr_dumpBER.
2766 Fixed bug in client.c which caused a crash when a scanResponse didn't
2767 contain positionOfTerm.
2769 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2770 * will cause an error in a client if a non-YAZ target sends both a
2771 * list of Scan entries and non-surrogate diagnostics.
2773 Retrieval module enhancements. Tag sets may be typed in the reference
2774 to it. From the .abs-file the "tagset" directive takes a third optional
2775 integer type for the tag set referenced. From a .tag-file the "include"
2776 directive takes a third optional type as well. The old "type" directive
2777 in the tag set itself is still recognized but acts as the default type
2780 Backend interface change. Individual Scan terms returned from bend_scan
2781 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2782 in include/backend.h.
2784 Retrieval module enhancements. Multiple tag sets and attribute sets may
2785 be specified in abstract syntax specs. Revised the error/warning for
2786 logging messages reported by the retrieval module when reading the
2789 Object Identifier system (oid_..) changed. The API is backwards
2790 compatible but the oid-routines now allocates new OID's when needed.
2791 Raw OID's may be specified in oid_getvalbyname.
2793 YAZ now uses GNU configure to generate Makefile(s).
2795 * Minor changes in some of the member names of DeleteResultSetRequest and
2796 DeleteResultSetResponse. See include/proto.h.
2798 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2799 and added member 'languages' in TargetInfo (which was missing).
2801 Changed the way attribute sets are handled in the retrieval
2802 module. These are now cached, just like the abstract syntaxes
2805 Changed YAZ so that it links with compiled ASN.1.
2807 Added Explain-schema definitions and mapping routines. The following
2808 Explain categories have been implemented: AttributeDetails,
2809 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2811 Fixed minor bug in Windows version of Server Library.
2813 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2815 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2817 Added EXTERNAL: UNIverse Resource Report (non-standard).
2819 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2820 ENUMERATED and SET OF.
2822 * Added 'const' to some of the char pointer arguments for the
2823 functions, data1_read_node, data1_getelementbytagname,
2824 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2827 Fixed bug in data1_insert_taggeddata - the last_child member of
2828 parent wasn't initialised.
2830 * Changed data1_read_record and data1_read_node so that the supplied
2831 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2832 doesn't refer to any parts of the "SGML"-buffer.
2834 Fixed bug in server library (Windows version of statserv_remove).
2836 * Changed code so that it compiles as C++. The type definition
2837 of Odr_fun which is a member of Odr_arm was changed. The result is,
2838 that an explicit typecast is needed for the fun pointer when
2839 using Odr_arm - as in:
2840 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2842 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2844 Implemented the new structured date and time definition as approved
2845 by the ZIG. Added schemaId element to the specificTag in Espec-1
2846 (also approved at the last ZIG). Thanks to RVDM.
2848 Added some Object identifiers (RVDM).
2850 Changed the Update Extended Service (RVDM).
2852 Added command "refid" to client which specifies referenceId for
2853 the following requests.
2855 Implemented extended service handling for server. See ztest.c
2856 for an example as well as backend.h. New handlers are registerd
2857 in the Init handler.
2859 * Changed interface for sort in server.
2861 Added new members to statserv_options_block. It allows a server
2862 to read options from another source than just the command line. Thanks
2863 to Charles Woodfield.
2865 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2866 renamed to zboolean. Some C++ compilers complained about the name.
2868 Minor changes to gils.abs. Added index 's' (sort) on title
2869 and date/time-last-modified.
2871 --- 1.4pl2 1998/1/30
2873 Fixed bug in server library regarding inetd mode (-i). This bug
2874 was introduced by release 1.4.
2876 --- 1.4pl1 1998/1/29
2878 Added sort facility in client and backend server interface.
2880 Fixed problem with dependencies in Makefile(s).
2882 Fixed bugs for encoders/decoders of extended services and
2885 Implemented sub-tree feature for schemas. Sub-trees are
2886 referenced in *.abs-files. See explain.abs for an example
2887 of the use of this feature.
2889 Modified bib1.att; local attributes for ANY didn't include
2890 ANY itself (only affects use of the retrieval module).
2892 Fixed bug in plain SGML reader in function data1_read_node:
2893 tags with prefix "var" was incorrectly interpreted as variants.
2895 Added feature "sub-schemas" to enable references to - and definitions
2896 of - group of elements.
2898 * Removed member parent from type data1_element (in data1.h).
2900 Implemented function odr_nullval() that returns the value of
2903 * Removed member num_children from data1_node (in data1.h).
2905 Made NT service interface part of the server library. The
2906 function statserv_main uses the NT service when required and
2907 calls the statserv_start / statserv_close routines.
2909 Routine zget_SearchRequest and zget_PresentRequest fills
2910 resultSetName/Id member with "default" instead of "Default".
2912 Fixed memory leak in server. Request queue member wasn't freed.
2914 Fixed nmem_exit so that memory is freed.
2918 Revised the CCL parser utility to be thread safe.
2920 Added function, oid_ent_to_oid, to replace the function
2921 oid_getoidbyent, which is not thread safe.
2923 * Added nmem_init and nmem_exit to initialize and release
2924 NMEM resources. Function nmem_init should be called once in the
2925 initial thread before NMEM/ODR is used. statserv.c and client.c
2926 have been changed accordingly. The change was necessary to make
2927 NMEM thread safe. The NMEM memory pool is shared amongst threads
2928 in a process. Unix-based applications will still work fine without
2931 Added NT Services interface for the the Z39.50 (statserv) Server.
2932 Refer to the ztest.c source on the usage.
2934 Windows 95/NT port using MSVC5.0. Project files are included in the
2937 * Defined new 'global' handle for the retrieval (data1) system. The
2938 new handled, data1_handle, describes the state of the data1 system.
2939 This handle is passed as first argument to virtually all
2940 data1 related routines. The functions data1_create and data1_destroy
2941 creates and destroys a data1 handle respectively.
2943 Added ODR encode stream member to all backend request structures
2944 init, search, scan etc. This stream should be used to allocate all
2945 memory used for the response when thread safe operation is needed.
2947 Changed the comstack utility, cs_addstr, to be thread safe. The
2948 returned hostname string returned by the function is now part the
2951 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2952 function. The cs_straddr takes a COMSTACK handle as argument, so this
2953 function must be used after cs_create and before bind/connect.
2954 This function is thread safe.
2956 Moved test server to 'ztest' directory - generic server code still
2957 in 'server' directory.
2959 Made prefix query (pquery.c) utility thread safe.
2961 Added new function modifier YAZ_EXPORT to 'export' public DLL
2962 functions when using windows (see include/yconfig.h).
2964 Added definitions to the OID database (util/oid.c) (RVDM).
2966 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2968 Added call to ccl_rpn_delete in client program.
2970 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2971 release of RPN structure.
2973 Added support for C++, headers uses extern "C" for public definitions.
2974 With input from RVDM.
2976 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2977 Thanks to Ronald van der Meer (RVDM).
2979 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2981 Added support for private extensions to the OID database
2982 (oid_setprivateoids()). Thanks to RVDM.
2984 Added optional, physical ANY (key replication)
2986 Fixed null-reference problem in GRS-1 output filter.
2988 Proximity operator added to Prefix Query Format (PQF).
2990 In test client command "base" accepts multiple databases.
2992 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2996 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2998 Smallish bug-fixes in the new encoders/decoders (explain).
3000 Bug fixed in DeleteRequest.
3002 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3004 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3006 Added SOIF syntax (using private OID for now) to retrieval module and client.
3008 Added Update extended service.
3010 Added SearchResult-1 additional info structure.
3012 Added optional CCL (ISO8777) interpreter as separate module. Available
3015 --- 1.2 1996/6/10 (1st anniversary release)
3017 Added Summary record syntax. Lightly tested.
3019 Added OPAC record syntax. Untested.
3021 Added ResourceReport service encoders/decoders. Untested.
3023 Fixed bug in z_Unit - wrong tagging on unitSystem.
3025 Fixed bug in the DiagRecs decoder.
3027 Added options for max PDU size and session timeout to frontend-server.
3029 Added documentation of query-language parsers and other supporting utilities.
3031 [frontend-server] Added Attribute set to the bend_scanrequest API.
3033 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3034 surrogate diagnostics were generated.
3036 [retrieval] Allow multiple local values for attribute.
3038 [retrieval] Allow multiple attributes per element in .abs files. index type.
3040 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3042 --- 1.1pl2 1996/4/10
3044 Minor changes, mostly specific to Zebra's requirements (retrieval)
3048 Repaired bug in frontend server when running multiple listening
3049 endpoints in dynamic mode.
3051 z_External() now won't break if a known, ASN.1 value comes encapsulated
3052 in an octet-string. The value will pass through unmodified in an Odr_oct.
3054 Added a bit of code to the demo client to decode & display
3055 ASN.1-structured records represented in the octet-aligned branch of
3056 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3058 Added z_ext_getentbyref() to the ASN module. Doc updated.
3060 * Completed the SCAN definition in the ASN module. This may break SCAN
3061 code based on older YAZ-versions at compile-time. The fix is easy -
3064 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3065 under the SCAN definition. Remember to initialize this, server-people.
3067 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3068 that this does not extend to ODR and ASN.
3070 Comstack allows insertion of established socket (primarily for
3071 inetd-operation of servers). Doc updated.
3073 Front-end server can now start from the inetd in TCP mode. Doc
3076 --- 1.0pl4 1996/1/24
3080 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3081 the rank and record number.
3083 Adjustments to the frontend server.
3085 Fixed diagnostic BER dumper. It ignored the file argument.
3089 Various changes to retrieval module.
3091 Changed the union discriminators of the protocol files from enums to
3092 ints paired with #defines.
3094 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3097 *Changed operator in the RPN structure to 'roperator', again to avoid a
3100 Fixed problems in Explain decoders/encoders.
3102 --- 1.0pl2 1995/12/6
3104 Memory bug in log module fixed.
3106 --- 1.0pl1 1995/12/5
3108 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3110 Bug in Explain DatabaseInfo module fixed.
3112 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3116 The shift to v1.0 signals that we now consider the *core* functionality
3117 of YAZ reasonably stable (the core being more or less equivalent to
3118 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3119 tested (Explain not at all - though that will happen soonish).
3121 Minor changes to code to support Windows port.
3123 Various minor changes after we're getting to use GRS-1 & co. more.
3125 Added Espec-1 format.
3127 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3128 of the protocol and it cannot be selected when encoding (maps into 'string'
3129 when decoding). Needed to talk to some servers.
3131 Demo client can request simple element set names.
3133 Added Diagnostic Format encoders/decoders.
3135 Added simple Close handling to frontend server (no hooks for resource
3136 reporting yet), and demonstration client.
3138 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3140 --- 1.0b3 1995/08/24
3142 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3143 handled incorrectly when records were requested in the searchResponse. This
3144 will only affect you if you use the frontend-server.
3146 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3147 Test-client will ask for and print GRS1. Ztest will return dummy records
3150 Added Explain encoders/decoders to the service-level API. Untested.
3152 Added Extended Services: Item Order encoders and decoders to the Service-
3153 level API. Untested. We could use a recent copy of the pertinent bits
3154 of the ILL protocol to add those bits.
3156 Added diagnostic format 1 encoders/decoders to the service-level API.
3159 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3160 odr_cons.c, which causes a more correct output.
3162 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3163 was always set to 0 when no records were requested in the searchRequest.
3165 * Added better external-handling. This shouldn't harm old code that
3166 *encodes* externals. It can break code that looks for a
3167 'single-ASN1-type' representation, since those types that are known
3168 are now decoded immediately. Look at the SUTRS sample code in
3169 seshigh.c and client.c. Documentation updated.
3171 Handling of structured records in bend_fetchresponse. Length -1 marks
3172 structured record, type is deduced from format field.
3174 --- 1.0b2 1995/06/27
3175 Fairly quick maintenance release to add SUTRS support.
3177 Fixed handling of SUTRS records in the demonstration client.
3179 * Added format field to the bend_fetchrequest and bend_fetchresponce
3180 structures of the backend API (frontend server). When the record is
3181 returned, the value of the format field is mapped to an OID. The
3182 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3183 of the record. The special value VAL_NONE in the bend_request means
3184 that no specific format was requested by the client. Documentation
3185 updated accordingly. Test server (ztest) will return a fixed dummy
3186 SUTRS record if your client requests SUTRS.
3188 Documentation updated accordingly.
3190 You can now set external libraries and RANLIB support in the top-level
3194 First public release.
