3 Fix nmem_strsplit_escape to substitute escape char properly.
5 New option for zoomsh -e , which makes it abort on first error and
6 return process exit code to indicate success/failure.
8 YAZ options utility supports special option -- which makes all it treat
9 all following arguments as non-options.
13 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
14 searched if absolute filename is given.
16 Fix conv_xslt() error-reporting when stylesheet is not found.
17 (The value of fullpath is meaningless in this situation.)
21 Fix problem in CQL sort node creation: un-initialized memory.
23 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
24 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
25 CQL sortby depending on whether Type-1 or CQL is actually sent to the
28 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
29 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
31 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
32 will make it possible to use both single-character mask (#) and wildcard (?)
33 in CCL . Throw diagnostic for left truncation because that is not supported
38 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
39 cases using escapes (\-sequences) and masking.
41 PQF parse fix: A trailing backslash followed by end-of-string (\0)
42 would result in a read one byte beyond string.
44 rpn2ccl may use Z39.50 masking for terms (t=z).
46 ICU check fix. Don't include library -lCrun on Solaris, unless present.
48 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
49 not --cppflags (which seeems like an error in icu-config).
51 -- 4.2.12 2011/08/27 RPM package only
53 cql2ccl: fix conversion of terms: operator characters were not
56 -- 4.2.11 2011/08/25 RPM package only
58 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
59 CCL parser will map both # and ? to their regular expression
60 quivalents (. and .*).
62 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
63 of reserved CQL characters.
65 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
66 is, so that they are passed through.
70 ZOOM SRU mode: more aggressive re-connect.
72 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
73 made available as a utility function, declared in <yaz/logrpn.h>
75 rpn2cql_structure() supports proximity nodes (except that the Type-1
76 proximity node's "exclusion" binary is ignored, as there is no way to
77 express that in CQL). Fixes bug #4564.
81 Fix SEGV that could occur if set command of zoomsh was given without
84 Fix SEGV that could occur if unsupported transport was given for
85 COMSTACK - say https (when SSL was unavailable).
87 Build yaz-url on Windows too.
91 New utility to get web content. Header is url.h. A command line tool
92 yaz-url is part of the distribution and packages.
94 Fixes for SSL COMSTACK (when gnutls is in use).
96 New functions yaz_base64{encode,decode}. Header is base64.h.
100 ZOOM C includes HTTP response buffer as additional info if it fails
101 to decode the SRU response.
103 Make wrbuf_json_puts available.
107 zoom: throw diagnostic for invalid value for option "sru". Before a
108 bad SRU request was sent.
110 Adding new utility wrbuf_vp_puts.
112 Add cclxmlconfig.obj to win/makefile. It was missing completely.
116 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
117 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
118 redirect was used at the same time.
120 MARC line mode decoding: be less picky about length given - first
121 5 digits of header that is.
123 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
125 Changes to decoding of SRU records: a record with recordPacking=xml is
126 modified with a new root element <yaz_record> if the recordData contains
127 multiple children elements. This is to make the record XML parseable
130 RPN to SOLR conversion: encode special characters.
132 Generic Frontend Server: fix uinitialized member, stepSize.
136 Fix a bug in SRU decoding of records.. The database records stored
137 had un-initialized memory, but it would only be seen with yaz_record_render
138 and type_spec="ext" .
140 Fix a bug in ccl_qual_dup introduced in 4.2.3.
144 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
148 Add new utilities to convert from CQL to CCL . These utilities have
149 prefix cql_to_ccl defined in cql.h.
151 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
152 lead to memory heap corruptions when ICU utilities were in use.
156 Make compilation work without Libxml2.
158 yaz-client: remove redundant blanks in display of searchResult-1 term
163 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
164 resulting CQL node (tree) in a new node CQL_NODE_SORT.
166 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
167 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
168 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
169 Note that the CQL sortby spec is only converted when the GFS is already
170 converting from CQL to RPN (cql2rpn element).
172 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
173 specify whether to collapse delimitors or not. The existing nmem_strsplit
174 do collapse (collapse parameter = 1).
176 Windows installer: For NSIS, set InstallDir depending on x86/x64.
178 Rename internal func yaz_use_attribute_create. While non-static, this
179 function is not declared in a public header.
183 Add -lCrun when linking with ICU on Solaris.
185 More quicks character set conversions for OPAC records.
189 fix problem with record_render: records were converted (character set
190 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
194 SRU: add methods for handling DADS SRU-proxy facets.
196 Separate OPAC record character set for ZOOM_record. yaz_record_render
197 allows a character set given as charset=from/opacfrom,to where 'from' is
198 the character set of a bibliographic record, 'opacfrom' is character set
199 of OPAC record and 'to' is the target character set.
203 yaz-client: show may XML format records. Command show followed by 'format'
204 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
207 src/stemmer.c: Avoid using unnamed union. It is not supported by some
210 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
213 Update yaz.spec to operate on both SLES11 / Centos 5.5.
215 RPM: Release includes 'indexdata' name. Use indexdata in release name so
216 this package can be distinguished from other vendors.
218 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
219 as determined by configure
221 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
223 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
224 returns no error and no record, the present request is considered
225 partial (only a subset of the records could be returned by backend), and
226 so it is appropriate to set Present Status to partial-4.
230 Move yaz-config man pages to section 1.
232 More documentation about SOLR.
234 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
235 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
236 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
237 peers on some Linux systems. However, in general that does not work
238 so YAZ can not rely on that to work. Debian changed behavior in this
239 respect from Debian lenny to Debian squeeze (still testing as of Oct
241 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
243 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
247 Fix yaz-config output: echo_source not set correctly by configure.
251 SOLR WebService support for yaz-client and ZOOM.
253 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
255 --- 4.0.12 2010/08/17
257 Z39.50 facet support. Facet specifications are passed for search in
258 other-information with ASN.1 as defined in facet.asn and OID
259 .10.1000.81.5 . Facets are expressed as an Attribute list as known
260 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
261 3 is limit (number of entries to get in response). yaz-ztest returns
262 dummy facets if a client asks for them.
264 --- 4.0.11 2010/07/09
266 CCL fixes: bug 2895 and bug 3539.
268 GR1-display: add comma in display - was removed by mistake in
271 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
273 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
275 --- 4.0.10 2010/06/18
277 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
278 result set from a connection. The result set will be on its own
279 thereafter; no operations on it will perform retrievals from a target.
280 Only cached copies are returned.
282 ZOOM C:fix case for HTTP servers responding with Connection:close.
283 Ensure that if there is a current task it is resumed (like fetching
284 more records in a result set) . Bug #3484.
286 PQF parser: use odr_atoi for Odr_int (not atoi)
288 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
289 values that contain any non-digits are treated as string attributes
290 (previously decoding only checked for leading character ([0-9]). PQF
291 encoding: attribute string values are not surrounded by double-quotes.
295 New utility for managing threads - thread_create.h.
297 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
298 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
299 but YAZ' implementation do.
301 Fixes for yaz_cond-functions on Windows 7.
303 DLL export more symbols.
305 zoomsh: show record do NOT render opac.
307 Remove *.la files from Debian and RPM packages.
311 Debian package libyaz-dev depends on libgnutls-dev again (was
312 removed in YAZ 4.0.6, but due to Libtool it is still needed
313 even though yaz-config do not list libgnutls libs).
315 ZOOM: Use only one WRBUF for returning string results for
316 ZOOM_resultset. Reduces memory usage for ZOOM in general.
318 ZOOM: ZOOM_connection do not use a shared pointer to
319 ZOOM_resultset after ZOOM_resultset is destructed by
320 user. Reverts to YAZ 4.0.4 behavior.
324 record-conv: fix problem with at least one XSL conversion -
325 due to probably incorrect usage of XML XSL documents.
329 Fix yaz-config for static mode and the use of SSL (gnutls).
333 Forward decl timeval struct in mutex.h and gettimeofday.h.
335 yaz-config: fix 'static' mode linking.
339 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
340 are wrappers for pthreads or Windows. For Windows these are put in
341 a separate DLL: yaz_cond4.
343 libyaz.la (whole source) is compiled with thread. If thread support
344 is enabled enabled, all source of YAZ is compiled with treading support.
345 This allows core utilities such as yaz_log to use thread facilities.
346 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
347 thread utilities. This commit moves mutex utilities (mutex.c) from
348 libyaz_server.la to libyaz.la.
350 yaz-json-parse displays leading text until error.
354 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
355 patch from Giannis Kosmas.
357 SRU: no longer URL encode SRU database. The URL for an SRU server is
358 a URL and such is alreeady encoded - at least when given with leading
359 http:// or https://. This reverts behavior to YAZ 3.0.50.
361 Support for new MARC XML notation TurboMARC which like MARCXML is a
362 complete representation of MARC/ISO2709.. This one, however, is more
363 compact and allows for faster processing with XSLT. TurboMARC can be
364 used in the marcdisp.h API, from the yaz-marcdump utility and from
367 yaz-ztest can be configured - via the database - to perform certain
368 delays when it performs operations search, present and single record
369 fetch. This allows testers to make yaz-ztest act as a real or even slow
370 Z39.50 server. Refer to the yaz-ztest man pages for details.
374 wrbuf_destroy allows NULL WRBUF passed to it.
376 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
378 Add ZOOM_connection_close.
380 No fixed size buffers for ZOOM shell - bug #3257.
382 tstodr: make it work on s390 platform.
384 New icu iterator-functions. The new icu_iter-functions makes it possible
385 to use ICU chains from many threads.
387 yaz-client: better syntax check for show command.
391 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
394 New simple local-file XML include facility which allows file glob-patterns.
395 Refer to yaz/xml_include.h.
397 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
400 ZOOM_record_get supports new parameter "format" which makes it format XML
403 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
404 JSONText in ECMA-262) is JSONValue, not JSONObject.
408 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
409 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
411 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
412 POSIX/Unix builds .so with major version 4.
414 Remove old LOG_-defines from log.h. They have been obsolete and
415 undefined by default for the last 5 years.
417 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
419 GFS: Remove socket (int *fd) from search_rr handler. The socket
420 descriptor ptr is a facility that allowed a search handler to supply
421 a socket which would serve as a callback - when search was complete.
422 This facility has now been in use for years.
424 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
425 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
426 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
427 returns 'const char *' rather than 'char *. The returned string is
428 read-only and should not be modified by applications. COMSTACK cs_close is
429 now a void function - it no longer returns int. No applications check for
430 the value and the implementations has always returned 0.
432 ZOOM: use size_t for scan hit counts and str size. Functions
433 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
434 occ (hit count) and len (string length) are now of type size_t pointer
435 rather than int pointer. This is to be able to represent large hit counts
436 and to also just to use the proper type for string length (strlen result).
438 New JSON parser. Refer to include/yaz/json.h .
440 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
441 Used to be int in some cases. Many wrbuf_-functions used to return an int
442 indicating some length.. These return values were never used. And so they
445 ODR: odr_malloc, odr_total now takes size_t for size.
447 clone_z_type: fix leak; occurred for encoding failures.
449 --- 3.0.52 2009/12/03
451 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
452 bug was introduced in 3.0.51.
454 --- 3.0.51 2009/12/02
456 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
458 tcpip comstack: fix leak for getaddrinfo.
460 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
461 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
462 Decoding of SRU "path" database is performed by private function
463 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
464 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
466 yaz-client: honor base command for SRU. Change when database setting
467 is applied for SRU and ensure it is kept when a connection is reset.
468 Change also the way errors are displayed or SRU (decoding of packages).
470 --- 3.0.50 2009/11/02
472 Add support for extra request / response data for SRU codecs and GFS.
473 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
474 for extra data response buffer and length. For the GFS, both request
475 and response data (XML) is carried in extra_args and extra_response_data
476 for the search handler. Patch by Ko van der Sloot.
478 ZOOM: For queries that cannot be converted to the specified rpnCharset,
479 ZOOM now returns a diagnostic on the client-side ('invalid query' /
480 10010). This fixes bug #2113.
482 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
483 cmdfile included a 'quit' command that would result in a memory violation.
485 --- 3.0.49 2009/10/01
487 Make a number of functions defined in xmlquery.c static. These have
488 never been declared in a public header file (yaz/xmlquery.h) and was
489 made public by mistake.
491 Improve speed of character conversions (iconv utilities). This makes
492 conversions from MARC-8 faster.
494 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
495 unless type desired is "raw". This will prevent type "xml" from
496 returning ISO2709 .. Which obviously can not be XML parsed.
498 Fix memory leak in ZOOM that would occur if option apdulog was used
499 on a re-used connection.
501 Frontend server logs HTTP requests.
503 Frontend server now sends Z39.50 close when it times out (sesssion has
504 been idle for too long). Versions 2.0.30 and earlier also sent close.
505 But due to a mistake this was disabled in all versions after that, i.e.
506 the server would just close the socket immediately.
508 yaz-client emits a better message when receiving an unrecognised
509 userInformationField.
511 Skip zero-length subfields when decoding ISO2709. This rare case happens
512 if a record has two FS characters in a sequence. Without this patch
513 there would be a reference beyond char array in using_code_len fragments
516 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
518 --- 3.0.48 2009/08/28
520 The show command offered by the zoomsh command now takes a 3d optional
521 parameter type which is what is passed to ZOOM_record. If the type
522 argument is omitted, "render" is used.
524 RPN to CQL conv may use USE string attributes (bug #2978).
526 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
528 --- 3.0.47 2009/07/08
530 Function yaz_xml2query allows a diagnostic element in the PQF XML
531 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
532 code and additional info respectively.
534 The BER BOOLEAN is now the integral type Odr_bool which still happens
535 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
536 typedef'd to Odr_int. This is still an integral 'int', but it may be
537 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
538 ASN-1 compiler as well as programs has been updated to use the new types.
540 --- 3.0.46 2009/06/08
542 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
543 only the bibliographic record was rendered. For type=opac, an OPAC
544 record is only returned if it is present.
546 iconv: small fix for encoding of advancegreek.
548 yaz-client: avoid double display of SRU/SRW records (bug #2798).
550 yaz-client: option auto_reconnect=on really reconnects.
552 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
554 server: avoid null ptr ref for for yaz_poll errors.
556 build: fix RPM build for RHEL 5.3.
558 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
560 --- 3.0.45 2009/03/31
562 Fixed bug #2709: TCP connect returns Invalid argument.
564 Fixed compilation for mingw.
566 Honor charset for raw records (ZOOM_record_get).
568 Fixed use of errno for threaded mode that was seen on Solaris 10.
570 Fixed argument passing with blanks in value for Windows Service.
572 Disable YAZ' own log rotate by default (no 1 GB limit).
573 The variable l_max_size which specifies the log file limit is set to 0
574 (DISABLED): This is due to the fact that YAZ is most often deployed using
575 logrotate. Also YAZ can not perform log rotate because of unsufficient
576 permissions (setuid).
578 --- 3.0.44 2009/02/17
580 List supported encodings in man page for yaz-iconv.
582 Fixed missing SSL libs for --libs output
584 Re-established OID record syntax application-xml. Nobody should use it
585 but we don't want to change soname because of this symbol being absent.
587 --- 3.0.42 2009/02/02
589 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
591 Added member named_result_sets for init handler struct for the GFS. This
592 allows a server to disable named result sets.
594 Removed OID record syntax application-xml.
596 Added support for rule-based transliterator for ICU wrapper of YAZ.
598 Fixed bug #1902: yaz-icu XML output.
600 Make YAZ checks Emacs friendly.
602 BITSTRING value shows value. Bug #2346.
604 ISO2709 decoding: skip control characters from indicator data.
606 Omit sort key by default in yaz-icu's output.
608 Allow combined single char options (again) for YAZ' options function.
610 Utility yaz-marcdump got option to display YAZ version (-V).
612 Allow YAZ to use ICU 3.4.
614 Added new ICU test case which illustrates removal of diacritics.
616 --- 3.0.41 2008/12/29
618 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
620 --- 3.0.40 2008/12/29
622 For configure, using option --without-xml2 also disables Libxslt/Libexslt
625 Fixed bug #2352: yaz-marcdump crashes for certain record.
627 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
629 Added support for Danmarc2 to UTF-8 conversion.
631 Added support for ISO5426 to UTF-8 conversion.
633 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
634 implementation version.
636 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
638 --- 3.0.38 2008/11/10
640 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
641 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
643 ZOOM C now interprets databaseName option for ZOOM connection as path
646 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
648 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
650 Dummy Libxml2 types no longer defined in headers of YAZ'.
652 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
655 --- 3.0.36 2008/09/26
657 Various ODR chapter fixes.
659 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
661 Added missing source for Windows compilation, mutex.c.
663 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
665 For SRU connections in ZOOM all records up to "count" are now fetched.
667 Fixed crash in generic frontend server (and yaz-ztest) which occurred
668 in Windows due to bad error handling for Libxml2.
670 Added facility for sending arbitrary records (ASN.1 any) using
671 ZOOM C's Extended service update. Patch by Sam Reynolds.
673 New options for ZOOM C's connection, logapdu which makes ZOOM log
676 --- 3.0.34 2008/06/18
678 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
680 --- 3.0.32 2008/06/12
682 Fixed memory violation that could occur when decoding UTF-8. This bug
683 was only present in 3.0.30 of YAZ.
685 --- 3.0.30 2008/06/06
687 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
688 GNU TLS is used by default (if found).
690 yaz-ztest returns OPAC records if a client asks for OPAC.
692 Improved speed of MARC-8 encoding.
694 Added support for lossy and loss-less MARC-8 encoding.
696 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
698 Added new Windows Service wrapper (sc).
700 yaz-client's itemorder command may now send a file.
702 Fixed yaz-marcdump to allow the use of NS prefix for record element.
704 Added new function yaz_log_xml_errors.
706 Allow (but warn) unknown XML attributes in MARCXML parsing.
708 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
710 The UTF-8 to MARC-8 conversion now uses a different set of characters
711 for Greek symbols. Bug #2120.
713 --- 3.0.26 2008/02/21
715 Added yaz_daemon (daemon.h).
717 Fixed bug #2068: pkg-config trouble
719 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
721 --- 3.0.24 2008/01/28
723 Document --with-xml2 option.
725 Added OPAC XML XSD (etc/opacxml.xsd).
727 Allow glob mask for name attribute in retrieval element for the
728 generic frontend server's retrieval facility.
730 Changed yaz_poll_poll to return yaz_poll_except for all returned events
731 except POLLIN/POLLOUT.
733 Fixed error handling in cs_listen. Bug #2037.
735 --- 3.0.22 2008/01/20
737 Fixed version in yaz/yaz-version.h.
739 Fixed bug #2027: Crash when closing connection.
741 Changed configure so that ICU support is only enabled if only ICU
742 and Libxml2 is available (because the ICU chain is XML based).
744 --- 3.0.20 2008/01/15
746 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
747 is built. Only this DLL depends on the ICU runtime.
749 yaz-ziffy is no longer part of YAZ. It is distributed separately by
750 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
752 Changed license of CCL module to 'Revised BSD'. After consultation with
753 remaining members of the original EUROPAGATE consortium, we are re-issuing
754 the CCL module without a separate license. The software was developed by
755 Index Data as part of a research project. The special license was included
756 to help feed usage information back to the project consortium to support
757 project evaluation. At this time, the project consortium has long-since
758 disbanded, and the majority of the original principals have retired. At the
759 same time, we have significantly modified the software during the following
760 years, to the point where very practically no original code remains. To
761 simplify re-use of the software, we have contacted those members of the
762 consortium who could be reached, and agreed to re-issue the module as a
763 proper part of the YAZ package.
765 Tcl scripts uses /usr/bin/tclsh as preferred shell.
767 CQL closer to being version 1.2 compliant. CQL also allows free-form
768 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
771 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
772 bug could make Extended services handling crash in the ZOOM layer. This
773 bug was only present in YAZ 3.0.18.
775 --- 3.0.18 2007/12/19
777 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
780 yaz-marcdump reads and writes collection wrapped records.
782 Handle OPAC for record conversion module.
784 Fixes for ICU wrapper.
786 Allow ICU libs to be controlled with --with-icu .
788 --- 3.0.16 2007/11/12
790 Added yaz_poll which is a wrapper for select/poll. When poll is available
791 and non-buggy, it is used, by yaz_poll . This allows more than 1024
792 sockets to be in use.
794 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
795 functionality through an XML based configuration (ICU chain). This system
796 is useful for search facilities such as Pazpar2 and Zebra that needs to
797 perform tokenization of indexed material. The ICU code in a separate
798 library libyaz3_icu.a.
800 Added HTTP tunnel facility for COMSTACK, bug #1752.
801 This is a facility that allows a Web proxy, such as squid, to tunnel
802 Z39.50 traffic. This facility is "transparent" to must applications
803 using YAZ. It's enabled by using pseudo transport connect: followed by
804 the proxy address, followed by command, then follwed by he regular
805 "virtual" addresss. For example,
806 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
808 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
810 --- 3.0.14 2007/09/21
812 Fixed bad memory reference in ZOOM_record - cuased by member not being
813 initialized. This was a problem only in YAZ 3.0.12.
815 Fixed bug in conversion from MARC to XML: Non-XML characters in control
816 fields were not removed.
818 Changed the way C code is generated from codetables.xml. Made a MARC-8
819 conversion trie for each characterSet section rather than codeTable.
820 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
821 of codetables.xml from Larry Dixson, LOC. Bug #1464.
823 --- 3.0.12 2007/09/12
825 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
826 from ZOOM_record_error).
828 ZOOM C function ZOOM_record_get returns record schema for type="schema".
830 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
832 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
834 Better SRW-to-Bib-1 diagnostic mapping.
836 ZOOM C and yaz-client announces SRU version 1.2 by default.
838 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
841 Fixed in yaz_sru_decode to allow other version than 1.1.
843 --- 3.0.10 2007/08/22
845 Added support for SRU scan for ZOOM.
847 Added support for the use of the older versions or Extended Service
848 Update in ZOOM. To faciliate this, an option "updateVersion" may be
849 set to the version , 1=first, 2=second, 3=third. The third version is
850 what ZOOM C has used so far. And that, obviously, is the default.
852 Added support for CCL queries in Z39.50 queries sent to the GFS (and
853 therefore in Zebra and in SimpleServer-based applications). The new
854 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
855 qualifier file used to transform incoming CCL queries into Type-1 RPN,
856 which is passed into the back-end search callback function.
858 Added support for HTTP Basic authentication in clients: the SRU/W
859 codec encodes the username/password elements of the PDU structure
860 appropriately, and these may be set using the "user" and "password"
861 options in ZOOM-C applications (the same options that are used for
862 Z39.50 authentication).
866 Fixed bug #1208: SSL appears to be broken in ZOOM.
868 Fixed bug #1206: Libxml2 include path weirdness.
870 Added oid_name_to_dotstring.
872 Allow elementSetName to be specified for ZOOM C record update.
874 Allow waitAction to be specified for ZOOM C based for Extended Services.
876 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
877 syntax OID. Bug introduced in YAZ 3 series.
879 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
883 Fixed bug #1157: yaz-client does not read .yazclientrc from current
884 directory. yaz-client now reads commands from file given by option -f
885 if specified; then tries to read .yazclientrc in current directory.
886 Failing that, it reads .yazclientrc from user's home directory.
888 Added support for correlationInfo Note and ID for Record Update via
891 Added yaz-client command querycharset which specifies character set for
892 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
893 (termListAndStartPoint).
895 Charset ISO5428:1984 is an alias for ISO5428-1984.
897 Implemented a way to perform scan in a result set using Z39.50. This
898 is achieved by attaching the result set name in the characterInfo
899 (type InternationalString) of OtherInformation in the Scan Request PDU.
900 The result set is identified in the otherinformation by the new OID:
901 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
902 This allows for scan in result set and faceted search . Zebra did some
903 of this in the APT term using attribute type 8 and value being result
904 set. Using the OtherInformation approach for this is cleaner and easier
905 to work with in proxies and the like. This facility can be used in
906 yaz-client using new command setscan which takes a result set as first
907 argument, start position (APT) as second.
909 Changed decoding of SRU XML packed records to deal with servers that
910 have recordData with XML data with multiple root nodes. Also make
911 comparison for recordPacking case insensitive. Again, one server
912 returns "XML" where others return "xml".
914 For SRU responses allow Content-Type application/xml as well as text/xml.
918 Fixed bug in character set conversion of BER strings. Bug introduced
923 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
925 For OID class, use oid_class consistently.
927 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
930 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
931 character set for bibliographic information interchange". By Giannis Kosmas.
933 Added documentation on new OID API.
937 Changes to generic frontend server interface: added new member
938 'query_charset' for bend_initrequest structure. A backend init handler
939 should set this member to its native character set for query terms.
940 When defined, the frontend server logic will announce this character set
941 to a client if the negotiationModel bit is set by the client. All server
942 implementors are encouraged to specify this. If a backend server does not
943 specify this a warning is issued using yaz_log(YLOG_WARN,..).
945 Added CCL utility to remove terms (stop words) from resulting RPN
946 tree. This is handled by functions with prefix ccl_stop_words_ .
948 New ZOOM C option, "rpnCharset", which allows client-side conversion of
949 terms in RPN queries.
951 Clean-up the CCL API. Moved some internal structures from ccl.h to
952 private header cclp.h. Changed ccl_parser_create so that a Bibset must
953 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
954 This is replaced by ccl_parser_find_str which takes a string instead.
956 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
957 libyaz.la is the core of YAZ except the generic frontend server and
958 does not depend on POSIX threads anymore. libyaz_server.la is the
959 generic frontend server facilities and uses POSIX thread functionality
960 if available. The libyaz.la no longer depends on POSIX threads because
961 the number of global structures is limited. NMEM no longer re-uses blocks
962 between threads ; it simply free's memory immediately but allocates in
963 "large" chunks as usual. We don't expect any performance penalties
964 because of this. The yaz_log system is still using a global log_level so
965 caution must be taken when modifying it with yaz_log_init_.. +
966 yaz_log_mask_str. This, however, should not cause any trouble because
967 these functions are called during initialization of application code
968 anyway. `yaz-config --libs server` returns libs for server applications;
969 `yaz-config --libs` returns libs for non-server applications.
971 New OID database - with public definitions in oid_db.h. Removed old OID
972 database including the head oid.h and definitions such as enum oid_value
973 and struct oident. The new OID database uses the same string names as
974 before but the 'protocol' is gone. There are now only two representations
975 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
976 converts from string to OID; functions with prefix yaz_oid_to_string
977 converts the other way.
979 Change to emit_term() in CQL-to-PQF query translation: when a term has
980 the /regexp relation modifier, do not process it for leading and
981 trailing "^" and "*", which have quite different meanings in regular
984 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
985 write handlers no longer carries a 'last' parameter. This will make
986 yaz_iconv flush "less" characters. A flush is performed by call to
987 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
989 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
990 removed, because function yaz_query_to_wrbuf does the same.
992 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
993 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
995 Deprecated MARC utility functions removed.
997 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1000 Branch split: YAZ_2_1_55_branch
1002 --- 2.1.54 2007/03/16
1004 Fix to ZOOM-C so that transparent reconnection is properly handled on
1005 connections that are in asynchronous mode.
1007 Fixed compilation on OpenBSD 4.0.
1009 Large strings in GRS-1 records are now properly displayed in yaz-client.
1011 Added character conversion support for "advancegreek"; based on patch from
1014 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1015 sequence is met. Before the error was not set so it would be unknown.
1017 Adjust yaz-marcdump MARC reader so that it skips until record separator
1020 --- 2.1.52 2007/03/07
1022 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1023 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1024 fd_set structure used as a bitmask for the FDs to be selected on.
1026 Using ACX_PTHREAD macro to check for POSIX threads.
1028 Fixed have-vsnprintf check.
1030 --- 2.1.50 2007/02/23
1032 Fixes for configure on BSD. Bug #900.
1034 Added snprintf/vsnprintf wrappers for systems that don't have
1035 limits (heavens forbid).
1037 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1038 created before all previous tasks were completed and removed from the
1039 task queue, the new task could be removed by a mistake.
1041 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1043 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1045 Fixed bug #832: Problem with MARC/charset in yaz-client.
1047 Fixed bug #668: save command line history for yaz-client.
1049 Fixed bug #830: pkg-config support.
1051 --- 2.1.48 2007/01/23
1053 Extended ZOOM result set options with two options that may be read by
1054 a client: resultSetStatus and presentStatus with values as specified for
1056 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1058 Fixed bug #827: Using SSL fails on Debian etch.
1060 Fixed bug #826: Weird looking chars for set of MARC records.
1062 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1063 that is treated as an ItemOrder with itemRequest being an XML document
1064 external. The value of "doc" is the content.
1066 Extended the GFS search facility. New member of bend_search_rr
1067 'estimated_hit_count' signals that hits is known to be an estmate
1068 (higher or lower than real hit count). New member 'partial_resultset'
1069 signals that the search was partial (hit count is lower or equal than
1070 real hit count). For Z39.50, the information is stored in resultSetStatus
1071 member of SearchResponse APDU. For SRU, the information is signalled
1072 via SRU diagnostic 59: "Result set created with valid partial results
1075 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1077 --- 2.1.46 2007/01/13
1079 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1081 Added ZOOM_connection_peek_event.
1083 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1084 the following new functions:
1085 ZOOM_event_nonblock, ZOOM_connection_process,
1086 ZOOM_connection_get_{socket,mask,timeout},
1087 ZOOM_connection_fire_event_{timeout,socket}.
1088 The existing blocking event handler, ZOOM_event, is a wrapper for the
1089 + blocking ZOOM_event_sys_{poll,select}.
1091 Implemented function ccl_xml_config which parses XML version of CCL
1092 configuration (bug #798).
1094 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1096 Added timings utility (yaz/timing.h)
1098 --- 2.1.44 2007/01/03
1100 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1103 Fixed bug #779: Rotation of apdu.log fails.
1105 Fixed for character set conversions:
1106 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1107 Honor G1 set in MARC-8 decoding.
1109 --- 2.1.42 2006/12/17
1111 Fixed bug #775: char conversion does not handle Alternative UTF-8
1114 Implemented function yaz_marc_read_line which parses MARC line format
1115 records. There is a wealth of formats out there. So far, this function
1116 reads line records produced by yaz_marc_write_line.
1118 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1119 more generic and easier to remember(!) options: -i format and -o format
1120 which specifies input format and output format respectively - where
1121 format is one of "marc", "marcxml", "line", "marcxchange".
1123 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1124 does not print anything except warnings for records.
1126 For yaz-marcdump, added support for MARC split into files (-s) with a given
1129 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1130 spec, at http://www.loc.gov/standards/sru/record-update/
1131 This has changed the binary layout of the following structs:
1132 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1133 bend_update_rr . Patch by Ko van der Sloot.
1135 Added GFS utility function bend_assoc_is_alive which returns 1 if
1136 association is still alive (client is connected); 0 otherwise (client
1137 closed connection). This allows busy servers to stop working for
1140 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1141 been a separate piece of software. This version of ziffy has been modified
1142 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1144 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1146 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1147 Client code may now interrogate options such as "init_opt_sort" to
1148 find out whether the server claims to support various options.
1150 --- 2.1.40 2006/11/27
1152 Added utilities yaz_{set,get}_esn to set/get element set name from
1155 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1156 of YAZ and has been so since YAZ 2.1.10.
1158 Implemented ZOOM_record_error which returns error information for
1159 record (surrogate diagnostic).
1161 --- 2.1.38 2006/10/31
1163 Updates for SRU Update by Ko van der Sloot:
1164 1. Changed name from "operation" to "action"
1165 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1166 versions in the code, marked as 'backward compatible'.
1167 3. Added diagnostics for SRU Update.
1169 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1171 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1173 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1175 For GFS, fixed problem with SRU diagnostic 'First record position out of
1176 range' being issued for 0 hits.
1178 zoomtst10 part of Windows Build.
1180 --- 2.1.36 2006/10/13
1182 Implemented yaz_filepath_comp which splits a path into file path
1183 components (required by Zebra 2.0.3+).
1185 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1186 BSD inspired license until now so this should not have any real impact on
1187 anybody. See http://www.opensource.org/licenses/bsd-license.php
1189 Fixed bug #687: Missing log lines.
1191 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1194 Fixed bug #689: SRU diagnostics to be added.
1196 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1197 whether a connection is idle (no more work do do).
1199 --- 2.1.34 2006/10/04
1201 Change type of optval from long to int for invocation of setsockopt with
1202 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1204 Added support for specifying the max log file size for the Generic
1205 Frontend Server. The size is given with option -r.
1207 --- 2.1.32 2006/09/21
1209 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1211 --- 2.1.30 2006/09/17
1213 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1216 Fixed bug in Generic Frontend Server that could cause a server to stop
1217 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1219 For the generic frontend server, the maximum record size is used as maximum
1220 size of incoming packages (SRU + Z39.50). The value until was previously
1221 only used in Z39.50 Init negotiation and, later, in a session controlled
1222 sizes of records returned. This is controlled using -k option. It can be
1223 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1225 --- 2.1.28 2006/09/04
1227 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1230 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1232 New option for yaz-marcdump -lpos=value which allows setting a portion
1233 of MARC header to a certain value.
1235 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1237 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1238 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1240 --- 2.1.26 2006/08/15
1242 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1245 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1247 --- 2.1.24 2006/08/08
1249 Fixed MARC ISO2709 encoding routines to deal with character set
1252 Minor changes to GFS logging. Database included in search request log
1255 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1256 cached/multiple records.
1258 Shared libraries are built by default on Unix+configure.
1260 Changed cql2pqf transformation to use a different evaluation order. The
1261 new order is: always, relation, structure, position, truncation, index
1262 and relationModifier. Old order was: always, relation, relationModifier,
1263 structure, index, position, truncation. Note that the the latter ones
1264 override former ones for identical attributes.. The new scheme means that
1265 it is possible to override any existing attribute with a relationModifier.
1266 And also that it is possible to override everything for the index rule
1267 (except the ones listed in relationModifier). No order is perfect but this
1268 one, we believe, covers more real cases.. The "always" should have been
1269 called "default", since the attributes there can be overridden with all
1272 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1273 compilation phase, but also for yaz-config --cflags output. This allows
1274 us to have public headers with Libxml2 stuff in them . It should also,
1275 eventually, make Libxml2 checks redundant in packages using YAZ, such
1278 --- 2.1.22 2006/06/15
1280 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1281 stored in uri, message and details.. Previously diagnostics were stored
1282 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1283 compatibility.. but he's probably the only one affected, so.
1285 Added support for CCL, compiled on the client side, in ZOOM-C. This
1286 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1287 input; the resulting query objects can be used for for searching with
1288 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1290 YAZ' configure searches for OpenSSL by default.
1292 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1293 SL_CTX_use_certificate_file. See
1294 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1295 for more info. Thanks to Ko van der Sloot.
1297 --- 2.1.20 2006/06/02
1299 Bug #600: SRU GET, POST support for yaz-client. Introduced
1300 command 'sru' which selects method SOAP/GET/POST.
1302 Allow missingValueAction to be specified for the sortspec string -
1303 function yaz_sort_spec. By default, the missing value action is null.
1304 Use ! to specify "abort". Use = followed by stringvalue to specify default
1307 Ensured that Present-handler (if defined) is called in GFS before any call to
1308 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1309 searchRetrieve requests.
1311 Documentation for YAZ is now based on the Docbook XML/XSLT using
1312 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1313 is no longer depending on jade/openjade or docbook-to-man scripts.
1314 PDF is no longer part of the distribution - but can optionally be
1315 made using DSSSL/jadetex or FOP.
1317 Added retrieval handling support in Generic Frontend Server to support
1318 conversion between MARC/XML as well as XSLTtransforms. See
1319 etc/yazgfs.xml for an example.
1321 Added Authentication support to Generic Frontend Server in SRU
1322 mode. Authentication using HTTP Basic is supported, as is the use
1323 of 'x-username' and 'x-password' parameters in the request itself.
1325 Added support for a new character set MARC8s identical to MARC8 except
1326 that it converts combined characters to single Unicode characters in the
1327 Latin-1 range (when possible).
1329 --- 2.1.18 2006/04/24
1331 ASN.1 compiler 0.4: generates brief Doxygen file header for
1332 generated .h/.c files.
1334 Utility yaz_iconv now supports conversion to MARC-8.
1336 New facilities for the MARC module. The reading - and writing of
1337 content are separate methods for the yaz_marc_t handle. The following
1338 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1339 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1340 format). Write functions have prefix yaz_marc_write_.. The existing
1341 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1342 available. Removed support for OAI-MARC and simplexml (not the
1343 simplexml from PHP5).
1345 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1346 to be returned for this connection.
1348 --- 2.1.16 2006/03/31
1350 Allow multiple languages and charsets to be specified with
1351 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1352 negcharset iso-8859-1,utf-8
1354 Translation of proximity nodes from CQL into PQF now works.
1356 Moved to automake 1.8, 1.9.
1358 Added function yaz_log_set_handler which allows a log handler to be
1359 installed. This handler will be called for all log messages. Output
1360 to file is also produced; but that can be disabled by passing NULL
1361 fname to yaz_log_init_file.
1363 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1365 For SRW (including GFS), accept application/soap+xml as content-type
1368 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1369 produces NO stylesheet reference even if a default stylesheet is specified
1372 --- 2.1.14 2006/03/14
1374 Updated Windows package to include yazd.dll + yazd.lib for the
1375 Development component.
1377 If the environment variable YAZ_LOG is set, then it is used as a
1378 string indicating the default level of logging to use if not
1379 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1380 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1381 used as before. So, for example, to omit warnings from YAZ logging,
1382 export YAZ_LOG=-warn
1384 cql_transform() now map structure and other attributes before indexes,
1385 so that index-specific structures and other attributes can override
1386 defaults. So now a combination of mapping specifications such as:
1388 index.dc.date = 1=date-modified 4=5
1389 does the right thing.
1391 cql_transform() now also respects the "always" mapping specification,
1392 which establishes an initial set of attributes to be used for all
1393 terms except where overridden by more specific attributes associated
1394 with the index, relation or modifier.
1396 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1397 which mode to use; one of "post", "get" or "soap" (SRW, default).
1399 Fixes for yaz_iconv routines: changed trie-based character set conversions
1400 to use only non-negative values for bit fields due to Sun's C compiler not
1401 supporting negative values.
1403 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1404 sequences where not read correctly. Fix by Rustam Usmanov.
1406 Updated win/makefile to use options, settings which makes things
1407 compile with VS C 2005.
1409 --- 2.1.12 2006/02/01
1411 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1413 In ZOOM socket code, use select instead of poll on MacOSX.
1415 ZOOM-C now support client-side compilation of CQL into RPN that is
1416 sent to the server, enabling CQL to be used against all Z39.50
1417 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1418 ZOOM_query object, and submit it using ZOOM_connection_search().
1419 The CQL-to-RPN translation uses a configuration file, the name of
1420 which must be specified in the Connection's "cqlfile" option.
1422 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1423 function, which takes as its start-term parameter a ZOOM_query object
1424 (which may have had either CQL or RPN set into it).
1427 --- 2.1.10 2005/11/29
1429 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1430 GFS to support this as well. Backend handler, bend_srw_update, does the
1431 update work. Code contributed by Ko van der Sloot.
1433 Allow retrieval of Search Result-1 information in ZOOM by the use of
1434 options that are attached to a result set. ZOOM documentation updated
1437 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1438 UTF-8 conversion. Patch by Raj Patel.
1440 Added option -m to GFS to control formatting of timestamps in log file.
1442 Added 'exit' as synonym for 'quit' in yaz-client
1444 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1445 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1446 for the new members. Patch by Ko van der Sloot.
1448 Added support for SRU POST. It is supported for content-type
1449 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1451 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1452 Instead make the library libyaz.la multi-threaded. Threading as a whole
1453 can still be disabled by configure option --disable-threads. Previosly,
1454 with older GLIBCs there were problems with MT libs under Apache. This
1455 has now been fixed a long time ago.
1457 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1460 CQL module modified to be case insensitive for relations/indexes/operations.
1462 Fixed bug in CQL transform code: incorrect value relationModifieder
1465 Added 'show all' command for yaz-client which retrieves all results
1468 Added new yaz-client, xmles, which takes a (private) OID and
1469 a document to be sent as an extended service request.
1471 Describe new yaz-client commands wait_response and set_auto_wait.
1473 Increase TCP/IP listener backlog from 3 (which I am guessing was
1474 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1475 that the socket will queue as many incoming connections as it's able
1476 to handle ongoing connections. In other words, it will never now
1477 refuse a connection that it would be able to handle merely because
1478 it's not got around to accepting() enough of the pending connections
1479 yet. This is the behaviour anyway under Linux, where the listen()
1480 argument is ignored; but not under BSD and on systems such as
1481 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1482 YAZ-based servers should now be uniform across operating systems in
1485 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1486 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1487 This allows yaz-marcdump to read large MARC batches (>2 GB).
1489 Modified all YAZ source files - except the source which is auto-generated
1490 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1493 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1494 corresponding to the existing *_setl() function. These allow option
1495 values containing arbitrary valuues.
1497 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1498 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1499 except that it returns an indicator of whether or not the sort
1500 criterion was accepted (0 for OK, -1 for invalid).
1502 --- 2.1.8 2005/06/07
1504 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1505 MARC output rather than returning "new" buffer.
1507 yaz-client warns about unknown init options.
1509 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1511 --- 2.1.6 2005/05/24
1513 Added support for SRW sort in Generic Frontend Server. Patch
1514 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1515 sortKeys - or NULL if none is provided.
1517 Fixed bug #307: It was impossible to specify indefinite/no timeout
1518 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1521 Added support for multiple languages and charsets to be specified in
1522 ZOOM. Each charset/language is separated by a blank. If negotiation is
1523 in effect in init-response, Option
1524 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1525 Code based on patch by Vasiliy Osadchuk.
1527 Fixed bug #306: infinite recursion that occurred when calling
1528 yaz_log_level_init as the first call (before other log level or
1531 Fixed bug in scan handling in front end server: if preferred-Position-In-
1532 Response was non-present, a NULL pointer referece was performed.
1534 --- 2.1.4 2005/04/26
1536 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1537 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1538 now defined for all those error codes. So instead of putting 109 in
1539 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1540 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1542 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1545 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1547 Program yaz-client now exits and produces an error message if multiple
1548 Z39.50 servers are specified on the command line (none or one allowed
1551 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1554 --- 2.1.2 2005/03/16
1556 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1558 Fixed bug #272: Preserve spacing for CCL terms.
1560 --- 2.1.0 2005/03/14
1562 Added support for virtual hosts and multiple backend servers for
1563 the YAZ frontend server. The configution is XML based and
1564 support specificition of CQL to RPN mappings and explain information.
1565 See section "Virtual Hosts" in the YAZ manual.
1567 Extended OPAC display utility. OPAC display utility renders
1568 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1569 to supplement yaz_marc_decode_wrbuf.
1571 Fixed a bug in MARC decoder that could caused it to crash for some
1572 invalid MARC records. More diagnostics and warnings where added in
1573 XML output (warnings, etc are stored in comments).
1575 --- 2.0.34 2005/02/08
1577 Fixes for UNIX domain sockets. Bug #261.
1579 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1581 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1582 Added yaz_marc_subfield_str which defines subfield lead string which is
1583 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1584 yaz_marc_endline_str which defines end of fields string used in
1585 YAZ_MARC_LINE format. Default string is newline.
1587 Experimental support for MarcXChange. This format can be produced
1588 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1589 http://www.bs.dk/standards/MarcXchange.xsd
1591 Added yaz-client commands scansize that sets maximum number of
1592 entries to be returned by scan.
1594 --- 2.0.32 2005/01/11
1596 Added support for SRW scan in yaz-client and Generic Frontend Server.
1598 * Added whereInList member to SRW Scan Term.
1600 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1602 Fixed NMEM system to return aligned blocks on the smallest boundaries
1603 that are suitably aligned for all possible types on the particular
1604 architecture YAZ is being built for.
1606 --- 2.0.30 2005/01/04
1608 Fixed numerious warnings that was issued with newer versions of GCC.
1610 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1611 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1614 Make YAZ Generic Frontend Server slightly faster.
1616 Enhance (and reduce) logging for Generic Frontend Server.
1618 Revert YAZ log system so that it flushes every write operation
1619 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1621 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1622 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1623 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1624 will effectively disable old definitions.
1626 --- 2.0.28 2004/11/09
1628 Added yaz_log_time_format which specifies log format using
1631 Added yaz_log_module_level which returns mask for a module. Value
1632 is non-zero mask a if module is enabled; zero if disabled.
1634 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1635 in include/yaz/cql.h.
1637 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1639 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1641 Fixed bug #172: RPM builds does not enable SSL.
1643 Doxyfile.in part of dist. Doxyfile generated by configure.
1645 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1646 are given and the corresponding component does not exist.
1648 Extend CCL documentation in YAZ reference. Describe r=r.
1650 --- 2.0.26 2004/10/01
1652 Fixed MARC->MARCXML conversion to properly deal with
1653 fields, subfields, indicators having non-ASCII characters.
1655 Fixed MARC->MARCXML conversion so that ASCII control characters
1656 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1659 Added YAZ GFS support for conversion from Z39.50 surrogate
1660 diagnostics to SRW surrogate diagnostics.
1662 Bug fix: YAZ GFS did not return schema in explainResponse.
1664 --- 2.0.25 2004/09/30
1666 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1667 now converts recordSchema to elementSetName as well as schema URI.
1669 Fixed bug in COMSTACK that prevented HTTP request packages from being
1672 --- 2.0.24 2004/09/29
1674 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1675 does not require white-space before and after the dash in a range, e.g.
1676 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1679 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1680 due to new GCC removing "redundant" code.
1682 Added yaz-client commands scanpos and scanstep that sets preferred
1683 position and step-size for scan.
1685 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1687 Added CCL utility ccl_qual_buf which parses one or more CCL
1688 spec lines in a buffer.
1690 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1691 of name and value - ignoring empty lines and comments.
1693 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1695 Added odr_get_element_path which returns current element path for an
1696 ODR handle. This utility is useful in error handling or user-defined
1699 Added ODR_PRINT utility odr_set_stream which is is a more generic
1700 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1701 to a write function and pointer to close function. The close function - if
1702 non-NULL - will be called during odr_destroy.
1704 Fixed bug in CCL parser where truncation char was not removed from
1705 right side when truncation=both was in effect.
1707 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1710 --- 2.0.23 2004/08/11
1712 Fix buffer overrun in CQL parser when dealing with proximity (%).
1714 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1715 to UTF-8/UCS conversion is now only based on codetables.xml.
1717 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1719 --- 2.0.22 2004/08/06
1721 Add support for more "commit changes" in ZOOM (uses Extended Services).
1723 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1726 Yet another small fix for configure of SSL.
1728 --- 2.0.21 2004/05/14
1730 Fix SSL libs for configure when --with-openssl=DIR is given.
1732 --- 2.0.20 2004/05/10
1734 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1736 SSL comstack now uses yaz.pem certificate file on server side
1737 by default. Certificate filename can be configured by calling
1738 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1740 Fix bug regarding multiple calls to ZOOM_connection_connect.
1742 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1744 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1745 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1747 ZOOM now allows inspection of X509 peer certificate for verification.
1748 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1750 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1751 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1752 as "modular" but it simplifies things.
1754 Added cs_get_peer_certificate to that returns peer X509 PEM.
1756 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1757 NULL if SSL is unavailable.
1759 Documentation about MARC decoding tools.
1761 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1763 --- 2.0.19 2004/03/30
1765 Rename CHANGELOG to NEWS to follow GNU style packing.
1767 Fix bug with missing initialization of member in init_diagnostics.
1768 This bug affects threaded version of GFS server.
1770 --- 2.0.18 2004/03/20
1772 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1775 Ensure zlib.dll is packed with Windows install.
1777 --- 2.0.17 2004/03/17
1779 Fix encoding of xsd:string to use text instead of CDATA.
1781 Fix endless loop in CQL parser with unbalanced ".
1783 Use a more compact way to store MARC-8 conversion tables.
1785 --- 2.0.16 2004/03/16 Debian only
1787 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1790 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1795 --- 2.0.15 2004/03/01
1797 Another fix for decoding of XML packed records.
1799 --- 2.0.14 2004/02/25
1801 Fixes for Chunked encoding. White space not ignored after length spec.
1803 Update NS and use default NS for SRW diagnostic elements.
1805 --- 2.0.13 2004/02/23
1807 Implement ZOOM_resultset_cache_reset which resets record cache.
1809 Implement ZOOM_resultset_sort which sorts a result set.
1811 Implement chunked HTTP transfer.
1813 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1815 --- 2.0.12 2004/02/16
1817 Added member 'schema' to bend_explain_rr structure so that backend
1818 can specify explain record identifier. Defaults to Zeerex 2.0.
1820 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1822 --- 2.0.11 2004/02/16
1824 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1827 Added init command for yaz-client which sends "extra" init request.
1829 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1830 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1832 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1834 Make ZOOM error code for "invalid query".
1836 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1838 --- 2.0.10 2004/02/05
1840 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1843 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1845 Added option -p <file> to make Generic Frontend Server to write PID file.
1847 Added option -D to put Generic Frontend Server in background on its own.
1849 Make ZOOM C recognize option "password". If unset, "pass" is used
1850 (for backwards compatibility).
1852 Fixed a bug in Generic Frontend Server that could make it crash if a
1853 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1856 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1857 Must be issued before open, in order to be in effect.
1859 --- 2.0.9-6 2004/01/12 Debian/Windows
1861 Make the SRU server more picky WRT unknown params, etc.
1863 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1865 New YAZ client command, options, that sets Z39.50 options.
1867 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1868 options from a string of tokens (one token for each option bit).
1870 Update SRW diagnostic code messages.
1872 --- 2.0.9-5 2004/01/07 Debian/Windows
1874 Handle user defined stylesheet for SRW/SRU.
1876 --- 2.0.9-4 2004/01/06 Debian/Windows
1878 Fix bug in decoding of Content-Length.
1880 --- 2.0.9-3 2004/01/06 Debian/Windows
1882 Fix a bug with decoding of XML packed records.
1884 --- 2.0.9-2 2004/01/05 Debian only
1886 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1888 Fix bug in SRW/SRU diagnostics decoding.
1890 --- 2.0.9 2004/01/05
1892 Fixed bug in Generic Frontend Server which could drop records exceeding
1893 preferred message size. Reported and fixed by Irina Dijour.
1895 Fixed calculation of package size for structured records in Generic
1896 Frontend Server. Reported and fixed by Irina Dijour.
1898 Fixed namespace for SRW/SRU diagnostics.
1900 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1902 --- 2.0.8 2003/12/22
1904 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1905 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1908 CQL changes to reflect recent changes to the specification:
1909 * Documentation talks about context sets instead of index sets.
1910 * Documentation talks about indexes instead of qualifiers.
1911 * The CQL-to-PQF transformer's configuration file now uses
1912 "index.set.name = <attributes>" instead of the old form
1913 "qualifier.set.name = <attributes>". (Both forms are still
1914 understood but the latter is deprecated.)
1915 * CQL terms with no explicit index specified are now interpreted as
1916 cql.serverChoice instead of srw.serverChoice (which of course
1917 behaves exactly the same.)
1919 --- 2.0.7 2003/12/16
1921 MARC conversion can now generate ISO2709 output in another
1922 character set. yaz-marcdump uses this facility if you invoke it
1925 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1926 functions from there can be used from C++.
1928 --- 2.0.6 2003/12/04
1930 Frontend server now transfers memory from decoded packages to stream
1933 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1934 references to show up.
1936 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1937 the ZOOM Abstract API. The older names for the same options are still
1938 also supported for the benefit of old applications.
1940 ZOOM-C supports "implementationId" and "implementationVersion" options
1941 to go along with "implementationName". These allow the user code to
1942 specify identification strings to be sent to servers.
1943 Add OID for the new ExtLite attribute set.
1945 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1946 as requested/supplid by Ere Maijala <ere@atp.fi>
1948 For generic frontend server, reverse the order of
1949 "toolkit-supplied / application-supplied" strings sent as implementationId,
1950 Name and Version. Also, remove the spaces around the slash. This brings
1951 the GFS in line with the behaviour of ZOOM-C on the client side.
1953 Add function ZOOM_scanset_display_term.
1955 yaz-client shows scan displayTerm if present.
1957 Utility yaz-iconv is now installed by default along with the man page
1960 Extend configure check for OpenSSL to use pkg-config where available (such
1963 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1964 server to specify uid/gid/mask for socket using the format
1965 unix:[user=uid,][group=gid,][umask=mask,]file=path
1966 If file= is omitted the existing format is assumed, e.g.
1968 in which case the mask is 0666 (rw for everybody).
1970 Major restructure of YAZ source. All source in libyaz is in src directory.
1971 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1972 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1974 Added man page for utility yaz-marcdump (used to be called marcdump).
1975 yaz-marcdump is installed by 'make install'.
1977 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1978 of incoming package failed.
1980 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1982 Change prototype of odr_perror: add const to message string.
1984 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1986 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1987 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1988 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1989 DNS lookup. There should not be any compatibility problems with this
1990 assuming that blocking=1 or 0 is used.
1992 Fix bad reference in UNIX comstack in function cs_addrstr.
1994 Fix for compilation on AIX.
1996 The generic front-end server (server/seshigh.c) now supports returning
1997 Init diagnostics to the client in User-information-field, in
1998 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2001 --- 2.0.4 2003/09/04
2003 Allow any CQL relation (not just all,any,exact,scr).
2005 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2006 that features the same UI.
2008 Implemented command update0 in YAZ client which is equivalent to
2009 update but uses old of Ext Update ASN.1.
2011 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2012 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2013 Previously no OID was used for this info.
2015 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2016 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2017 returns 'malformed search term' otherwise.
2019 SortResponse member resultCount now set to NULL in sort handler of
2022 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2025 Add three new utility functions for translating OIDs between various
2026 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2027 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2028 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2029 char *oid_to_dotstring(const int *oid, char *oidbuf);
2030 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2032 Reverted modifications for ES Update definition for z_IU0Update
2033 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2034 is back to YAZ 2.0.2.
2036 String value attributes for CCL parser.
2038 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2039 which their FirstSearch server returns in Init responses, sometimes
2040 carrying useful diagnostic information when Init fails. This has the
2041 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2042 "z39.50/oclcui.asn", where its definition is somewhat different from
2043 what OCLC document on their web-site, as required to interoperate with
2046 Support for anonymous authentication in yaz-client. Use the command
2049 * Fix the OID of the Index Data-local "admin" Extended Service from
2050 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2051 the 1000, which indicates a locally-defined OID, was a mistake.
2053 --- 2.0.3 2003/06/20
2055 Fix CCL directive @case handling so that it affects string match for
2056 both CCL keywords and qualifiers.
2058 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2059 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2060 Decoder has been updated with ASN.1 changes as listed in
2061 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2062 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2063 z_IUUpdate, remains unchanged.
2065 ZOOM_record_get may now return a record in a specific character set.
2066 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2067 "from" is the character set of record as returned by target. "to" is
2068 the character set to be returned. If omitted, "to" is UTF-8.
2070 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2072 New ODR utility, odr_getelement, which returns name of element for
2073 which encoding/decoding failed.
2075 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2076 in cases where a required element was omitted.
2078 Bug fix: some MARC8 sequences were not converted.
2080 New ZOOM option "step" which specifies number of records to be
2081 retrieved in one chunk. Used in conjunction with "start" and "count".
2083 SRW support for yaz-client. Use scheme http: to use it, e.g.
2086 yaz-client no longer does (un)intelligent character set conversions
2087 by default. Can be enabled with charset and marc_charset commands.
2089 xmalloc trace fix for 64-bit systems such as DEC alpha.
2091 Solaris 2.6 compile fix.
2093 New function, cql_strerror() translates SRW error codes, as returned
2094 by cql_transform_error(), into human-readable English strings. Used
2095 in yaz-client diagnostics when appropriate.
2097 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2098 converts it into a type-1 query which is sent to the server. This
2099 makes CQL available for use with all Z-servers, as opposed to the tiny
2100 minority that can handle CQL queries themselves.
2102 --- 2.0.2 2003/04/28
2104 New Debian package layout similar to the Redhat Package layout.
2106 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2107 and search result respectively.
2109 --- 2.0.1 2003/04/25
2111 Redhat package is now several packages: libyaz (runtime libraries),
2112 libyaz-devel (development and documentation, and yaz (utility programs).
2113 Package spec file by Morten Bogeskov.
2115 New member 'schema' in struct bend_fetch_rr which the name of requested
2116 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2117 handler MAY set this to reflect the schema of the returned record.
2119 New member 'display_term' in struct scan_entry. GFS now sets member entries
2120 and allocates scan entries to be filled by user scan handler. In previous
2121 version, entries member was allocated by the scan handler. That still works,
2122 but the GFS will ignore member display_term - assuming it was NOT set by
2123 the handler. The fact that the GFS now allocates the entries both allows
2124 for new members and makes a scan handler easier to write.
2126 Fix CQL lex buffer overflow.
2128 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2129 SRU default recordPacking is string.
2131 SRU protocol support for frontend server.
2133 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2135 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2137 Added scan for the ZOOM shell (zoomsh).
2141 * String Identifers for Schemas (Amendment 5).
2142 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2143 Old definition for schema
2144 Odr_oid *schema; /* OPT */
2149 Z_InternationalString *uri;
2150 #define Z_Schema_oid 1
2151 #define Z_Schema_uri 2
2154 * resultCount parameter to Sort Response (Amendment 1).
2155 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2157 Support for SRW 1.0 over HTTP. This is an optional feature and
2158 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2161 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2162 on the same port. SRW SearchRetrieveRequests are mapped
2163 to bend_init,bend_search,bend_fetch,bend_close.
2165 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2167 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2168 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2170 ZOOM connections are SRW based if schem http is used for hostname
2171 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2172 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2174 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2175 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2176 distance=n, order=true/false, relation=le, prox unit=word. If
2177 n is omitted, distance 1 is used.
2179 Fixed problem with C compiler include path in wrong order.
2181 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2182 on Solaris. Patch from Ko van der Sloot.
2184 New MARC decode API. All new functions operate on a yaz_marc_t
2185 handle. The most important new functions are: yaz_marc_create,
2186 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2187 decode and destroy respectively. Decoder can produce formats
2188 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2189 include/yaz/marcdisp.h.
2191 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2192 to UTF-8, UCS-32, wchar_t or Latin-1.
2194 * Prototypes for yaz_iconv_-functions moved to separate header
2195 include/yaz/yaz-iconv.h.
2197 Make a few private functions 'static' in unix.c. This prevents
2198 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2200 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2201 are set when Init Response is received.
2203 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2204 but returns diagnostic set as well.
2206 New function yaz_strerror which is a portable wrapper for
2207 strerror/strerror_r/GetLastMessage.
2209 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2210 is returned for MARC. If type is "oai", then OAI MARC is returned.
2212 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2215 --- 1.9.2 2002/11/26
2217 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2219 Fix bad race conditions on SIGTERM and terminate gracefully in
2222 Move retrieval (data1) module to Zebra since nobody seems to be
2225 Add GRS-1 render for ZOOM using same format as yaz-client.
2227 --- 1.9.1 2002/10/05
2229 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2231 Fix broken ESpec handling in data1 module.
2233 SGML reader parses comments and makes them part of the data1 tree.
2235 Added several type casts so that YAZ compiles as C++ code.
2237 ZOOM didn't handle PDU encoding failures properly.
2239 Added more Bib-1 diagnostics (approved extensions).
2241 GNU configure: better check for iconv.
2243 More portable use of accept, getpeername. Check for socklen_t. Use
2244 int/size_t if socklen_t is not defined.
2248 PQF parser rejects bad queries - including those with extra
2249 characters in them. PQF parser used to silently ignore that.
2250 Cleaner API for PQF added, which allows you to get detailed
2251 error information for bad queries (see yaz/pquery.h).
2253 Fixed bug in ZOOM_record_get for type "database".
2255 Implemented mini iconv library supporting conversions between
2256 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2258 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2260 --- 1.8.9 2002/08/20
2262 Fixed ZOOM C record cache so that preferredRecordSyntax and
2263 elementSetName is used to check for already fetched records.
2265 --- 1.8.8 2002/08/02
2267 Added three members in bend_initrequest structure to facilitate
2268 character set negotiation.
2270 Fixed a bug in frontend server that could cause indefinite
2271 loops under rare conditions.
2273 Revised character set utilities (charneg.h) so that encoding
2274 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2276 For PQF, directive @term <type> sets term type for Scan/Search.
2277 Here <type> is general, string, numeric, null. The term type
2278 is inherited - just like @attr.
2280 New call odr_set_charset that sets character set conversion for
2281 international-strings on a ODR stream. Prototype is:
2282 int odr_set_charset(ODR o, const char *to, const char *from);
2283 The InternationalString is still represented as C string in YAZ
2284 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2285 won't). On the protocol level, you can use any encoding.
2287 Support for UNIX sockets in ZOOM.
2289 Solaris recv sometimes returns errno == ENOENT. It is treated as
2290 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2292 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2293 both client and server. Code by Morten Bogeskov.
2295 --- 1.8.7 2002/05/22
2297 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2298 that they can be used directly from Visual Basic. You must recompile
2299 your windows APP if you're using ZOOM.
2301 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2302 Commands "lang" and "charset" sets language and character set respectively.
2303 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2304 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2306 Attributes from multiple CCL fields may be OR'ed rather than merged
2307 using directive "@field or". Fields are still merged by default -
2308 equivalent to "@field merge".
2310 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2313 Fixed bug in zget for parameter ExtendedServicesResponse.
2317 --- 1.8.6 2002/03/25
2319 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2321 Client displays USR.1:SearchResult-1 (hits per term).
2323 Additional Search Info for search in Generic Frontend Server.
2325 Fixed CCL parsing of "field=s".
2327 WIN32 installer - using the excellent NSIS software from nullsoft.
2329 Fixed CCL parsing of "field = - <number>".
2331 Added function yaz_marc_decode that decodes MARC for line mode
2332 display or XML (similar to that used by JZKit).
2334 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2335 Z39.50. But ISO/ILL was, however.
2337 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2338 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2340 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2341 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2343 --- 1.8.5 2002/02/03
2345 New YAZ client features: Command completion and new commands:
2346 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2347 Code provided by Jacob Poulsen.
2349 New call oid_trav, that visits all registered OIDs via callback.
2351 Function ZOOM_record_get now returns const char pointer rather than
2352 void pointer. It saves a lot of type casts.
2354 For YAZ client, command "auth" now allows you to set authentication
2355 in IdPass style. It is enabled when three tokens are given - order
2356 is user, group and password.
2358 Fix memory leaks in MARC record handling for ZOOM.
2360 New option for YAZ client, -k <kilobytes> that sets
2361 maximum record size. Similar to -k option for generic frontend
2362 server and yaz-ztest.
2364 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2366 Prefix query parser reports "fail" when bad attribute set is given.
2368 Fix in MARC decoder. Proximity logging. Fix for attribute set
2369 in scan handler for server. Patches by Shigeru Ishida.
2371 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2374 Configure option --with-openssl=<dir> now works when a directory is
2375 specified. Patch provided by Morten Bogeskov.
2377 New option for YAZ client, -u <auth>, that sets authentication.
2379 ZOOM fix: error information was sometimes "missing", since error
2380 was cleared/reset too when it shouldn't.
2382 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2384 --- 1.8.4 2002/01/04
2386 Scan for ZOOM API. New object ZOOM_scanset. New functions
2387 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2388 ZOOM_scanset_destroy.
2390 New ZOOM function, ZOOM_connection_last_event, that returns type
2391 of last event (such as "receive data", "send data", "apdu received",
2394 New ZOOM option, schema, that specifies schema for retrieval.
2396 New CCL feature. Qualifiers can be aliases for one or more
2397 other qualifiers (if more than one is given, OR is used).
2399 ZOOM uses named result sets if target supports it.
2401 Two new YAZ client commands: . (dot, which sources a script of YAZ
2402 client commands), and ! (to execute shell command.). Implemented
2405 Working on Debian packages.
2407 --- 1.8.3 2001/11/19
2409 YAZ client enables named result sets only if target supports it.
2411 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2413 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2414 with key="host" to get same result.
2416 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2417 Function Z3950_resultset_record(s) returns references to records
2418 "owned" by resultset. To become owner use Z3950_record_clone.
2420 Function z_ext_record handles Extended Services. Thanks to
2423 --- 1.8.2 2001/11/12
2425 CCL Parser fix: ignore token comma when dealing with and-lists.
2427 Documentation updates for COMSTACK.
2429 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2430 Changed prototype Z3950_records. For some functions, int parameters
2431 were changed to size_t.
2433 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2436 New MARC decode/display function, marc_display_exl, which properly rejects
2437 non-ISO2709 records. YAZ client uses it.
2439 --- 1.8.1 2001/10/29
2441 Fix bug: local attribute set wasn't set correctly in PQF strings.
2445 * Old Z39.50 codecs no longer supported.
2447 Added ZOOM C binding. See http://zoom.z3950.org/
2449 Renamed states for COMSTACKs to avoid confusion with events.
2451 Implemented cs_look and proper cs_rcvconnect.
2453 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2455 Configure detects POSIX threads on OpenBSD.
2457 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2458 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2460 When error is returned from present handler, non-surrogate diagnostic
2461 is returned in present response (and fetch handler is no longer called).
2463 * Minor adjustments to pquery parser (PQF). Token characters may be
2464 escaped by using backslash (C-style).
2466 PQF parser allows string attribute values to be specified. For @attr,
2467 non-numeric characters after the equal-sign are treated as strings
2468 (e.g. @attr 9=title).
2470 CCL trunction character may be defined (@truncation in file)
2472 * function zget_ExtendedServicesRequest sets waitAction to
2473 waitIfPossible (was wait).
2475 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2478 CCL operator names may be set in field definition files (CCL_bibset).
2479 See ccl/bib1 for an example.
2481 Fixes in ASN.1 compiler for C++ compatibility.
2483 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2484 and "op_or" to avoid conflict with C++.
2486 Fixed problem with GNU readline detection on Redhat 7.0.
2488 Added step-size for Scan backend handler.
2490 Fixed bug that made the frontend server crash when no attribute
2491 set was specified for scan.
2493 Front-end server automatically switches to original working directory
2494 when installed as an NT service. Previously -w had to be specified to
2497 Added extended attributes for retrieval module (data1), so that data1
2498 records carry d1_readXML/SGML attributes. d1_read also supports
2499 null-data rules ( <tag/>)
2501 On UNIX when POSIX threads are available, a separate library libyazthread
2502 is created. Programmers should link with that library and the yaz library
2503 when using threads. The reason for the split was that some applications
2504 on Linux, such as Apache, doesn't work well when using shared objects that
2507 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2508 (or any frontend server) in SSL mode by specifying ssl: followed by
2509 address. Only tested on UNIX.
2511 Added feature for CCL module. Virtual structure s=al or s=ol generates
2512 and-list and or-list respectively instead of phrase search.
2516 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2517 log_mask_str. This was done to avoid name conflicts with other libraries
2518 (such as other PHP extensions).
2520 Added raw OID member for preferred record syntax (request_format_raw)
2521 and returned record syntax (output_format_raw) for backend fetch method.
2523 Config file yaz-config now accepts options so that it returns specific
2524 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2526 Shared library support for UNIX using GNU libtool.
2528 * Modified backend interface. Request/Response struct's replaced by
2529 one read/write C struct. For example bend_fetchrequest and
2530 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2531 Every handler - even search has to be registered in bend_init
2532 handler. This means that the YAZ library no longer refers to
2533 external functions and it makes it possible to make the whole
2534 thing a single DLL/SO.
2536 Added Segment handler for backend server.
2538 Added Zmbol/Zebra administrative functions to YAZ client.
2540 Threaded frontend server on UNIX (when POSIX Threads are available).
2541 Starting the server with option -T enables multi-threading.
2545 Added configure option --enable-comp/disable-comp to control use
2546 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2547 located in sub directory asn.
2549 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2550 in ${exec_prefix}/bin along with the other programs yaz-client and
2553 GNU automake used to maintain makefiles.
2555 Added several OID's.
2557 Changed retrieval module so that we can load records with no abstract
2558 syntax defined. Tagpaths in these records are fully composed of string
2561 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2565 On UNIX, the generated makefile now supports a proper 'make install'.
2566 The prefix can be set via GNU configure to set the install location
2567 (default is /usr/local).
2569 * YAZ programs client and ztest were renamed to yaz-client and
2570 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2571 locations, such as /usr/bin,/usr/local/bin,etc.
2573 * YAZ Header files were moved from include to include/yaz. YAZ Header
2574 files are referred to as include <yaz/log.h> rather than <log.h>.
2575 The YAZ include path (-I ..) is therefore the same as before. Programmers
2576 should update their #include statements or use -Ipath/include/yaz
2577 instead. The main motivation for doing this change is that YAZ header files
2578 can be installed in "standard" locations /usr/include,/usr/local/include
2579 without introducing conflicts, since ALL YAZ header files are stored
2580 in subdirectory yaz (under /usr/include for example).
2582 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2583 rather than project/workspace files. We switched because project files
2584 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2587 Changed name of logging function, logf, to yaz_log, to prevent name
2588 clash with some math-log functions. The YAZ header log.h defines logf
2589 to yaz_log (#define) so there should be no incompatibilities by this
2592 Added bend_start/bend_stop handlers for server. These handler are
2593 called on start/stop of server. For windows they are called whenever
2594 a service is started/stopped.
2596 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2597 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2598 in util/yc.tcl. The auto-generated C code structures are, in a few
2599 cases, incompatible with the old decoders. There are differences in the
2600 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2601 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2602 The preprocessor variable ASN_COMPILED is defined when the compiled
2603 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2604 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2605 wish to use the old encoders/decoders you can specify --disable-yc
2608 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2609 version so that it supports both new - and old version of DB Update
2611 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2612 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2613 change. The name parameter can be set to 0 in which no name is specified
2614 for the construction. The macros odr_implicit and odr_explicit sets name
2615 parameter to zero for the construction involved. New macros
2616 odr_implicit_tag and odr_explicit_tag are similar to the others,
2617 except that a name parameter is added. For programmers' that don't use
2618 ODR they probably only need to change the call to z_APDU and z_External.
2620 Added access control facility by interfacing the TCP wrapper library.
2621 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2622 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2623 name of the daemon and enables the access control as specified in
2624 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2626 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2627 den Dool <H.M.vdnDool@kub.nl>.
2629 Added reference ID parameter to most functions in server API - refer
2630 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2632 Changed name of ccl library to libccl.a (was ccl.a).
2634 Fixed bug in decoder for Explain (Category TargetInfo).
2636 Added support for GNU readline in client. Thanks to Jacob Poulsen
2637 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2639 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2640 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2641 IMPLEMENTATION! This change was made to the development version before
2642 the ZIG decided to retract the amendment. If any users MUST be
2643 compatible with the original Update definition, PLEASE CONTACT US, and
2644 we will include a separate definition corresponding to the old Update
2645 ES. Note that because of the change to the ASN.1 of the
2646 TaskPackageRecordStructure we cannot define a single structure that
2647 will support both versions.
2649 * Added const modifier to buffer parameter for some ODR/BER encoding
2650 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2651 completeWAIS, odr_dumpBER.
2653 Fixed bug in client.c which caused a crash when a scanResponse didn't
2654 contain positionOfTerm.
2656 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2657 * will cause an error in a client if a non-YAZ target sends both a
2658 * list of Scan entries and non-surrogate diagnostics.
2660 Retrieval module enhancements. Tag sets may be typed in the reference
2661 to it. From the .abs-file the "tagset" directive takes a third optional
2662 integer type for the tag set referenced. From a .tag-file the "include"
2663 directive takes a third optional type as well. The old "type" directive
2664 in the tag set itself is still recognized but acts as the default type
2667 Backend interface change. Individual Scan terms returned from bend_scan
2668 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2669 in include/backend.h.
2671 Retrieval module enhancements. Multiple tag sets and attribute sets may
2672 be specified in abstract syntax specs. Revised the error/warning for
2673 logging messages reported by the retrieval module when reading the
2676 Object Identifier system (oid_..) changed. The API is backwards
2677 compatible but the oid-routines now allocates new OID's when needed.
2678 Raw OID's may be specified in oid_getvalbyname.
2680 YAZ now uses GNU configure to generate Makefile(s).
2682 * Minor changes in some of the member names of DeleteResultSetRequest and
2683 DeleteResultSetResponse. See include/proto.h.
2685 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2686 and added member 'languages' in TargetInfo (which was missing).
2688 Changed the way attribute sets are handled in the retrieval
2689 module. These are now cached, just like the abstract syntaxes
2692 Changed YAZ so that it links with compiled ASN.1.
2694 Added Explain-schema definitions and mapping routines. The following
2695 Explain categories have been implemented: AttributeDetails,
2696 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2698 Fixed minor bug in Windows version of Server Library.
2700 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2702 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2704 Added EXTERNAL: UNIverse Resource Report (non-standard).
2706 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2707 ENUMERATED and SET OF.
2709 * Added 'const' to some of the char pointer arguments for the
2710 functions, data1_read_node, data1_getelementbytagname,
2711 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2714 Fixed bug in data1_insert_taggeddata - the last_child member of
2715 parent wasn't initialised.
2717 * Changed data1_read_record and data1_read_node so that the supplied
2718 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2719 doesn't refer to any parts of the "SGML"-buffer.
2721 Fixed bug in server library (Windows version of statserv_remove).
2723 * Changed code so that it compiles as C++. The type definition
2724 of Odr_fun which is a member of Odr_arm was changed. The result is,
2725 that an explicit typecast is needed for the fun pointer when
2726 using Odr_arm - as in:
2727 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2729 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2731 Implemented the new structured date and time definition as approved
2732 by the ZIG. Added schemaId element to the specificTag in Espec-1
2733 (also approved at the last ZIG). Thanks to RVDM.
2735 Added some Object identifiers (RVDM).
2737 Changed the Update Extended Service (RVDM).
2739 Added command "refid" to client which specifies referenceId for
2740 the following requests.
2742 Implemented extended service handling for server. See ztest.c
2743 for an example as well as backend.h. New handlers are registerd
2744 in the Init handler.
2746 * Changed interface for sort in server.
2748 Added new members to statserv_options_block. It allows a server
2749 to read options from another source than just the command line. Thanks
2750 to Charles Woodfield.
2752 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2753 renamed to zboolean. Some C++ compilers complained about the name.
2755 Minor changes to gils.abs. Added index 's' (sort) on title
2756 and date/time-last-modified.
2758 --- 1.4pl2 1998/1/30
2760 Fixed bug in server library regarding inetd mode (-i). This bug
2761 was introduced by release 1.4.
2763 --- 1.4pl1 1998/1/29
2765 Added sort facility in client and backend server interface.
2767 Fixed problem with dependencies in Makefile(s).
2769 Fixed bugs for encoders/decoders of extended services and
2772 Implemented sub-tree feature for schemas. Sub-trees are
2773 referenced in *.abs-files. See explain.abs for an example
2774 of the use of this feature.
2776 Modified bib1.att; local attributes for ANY didn't include
2777 ANY itself (only affects use of the retrieval module).
2779 Fixed bug in plain SGML reader in function data1_read_node:
2780 tags with prefix "var" was incorrectly interpreted as variants.
2782 Added feature "sub-schemas" to enable references to - and definitions
2783 of - group of elements.
2785 * Removed member parent from type data1_element (in data1.h).
2787 Implemented function odr_nullval() that returns the value of
2790 * Removed member num_children from data1_node (in data1.h).
2792 Made NT service interface part of the server library. The
2793 function statserv_main uses the NT service when required and
2794 calls the statserv_start / statserv_close routines.
2796 Routine zget_SearchRequest and zget_PresentRequest fills
2797 resultSetName/Id member with "default" instead of "Default".
2799 Fixed memory leak in server. Request queue member wasn't freed.
2801 Fixed nmem_exit so that memory is freed.
2805 Revised the CCL parser utility to be thread safe.
2807 Added function, oid_ent_to_oid, to replace the function
2808 oid_getoidbyent, which is not thread safe.
2810 * Added nmem_init and nmem_exit to initialize and release
2811 NMEM resources. Function nmem_init should be called once in the
2812 initial thread before NMEM/ODR is used. statserv.c and client.c
2813 have been changed accordingly. The change was necessary to make
2814 NMEM thread safe. The NMEM memory pool is shared amongst threads
2815 in a process. Unix-based applications will still work fine without
2818 Added NT Services interface for the the Z39.50 (statserv) Server.
2819 Refer to the ztest.c source on the usage.
2821 Windows 95/NT port using MSVC5.0. Project files are included in the
2824 * Defined new 'global' handle for the retrieval (data1) system. The
2825 new handled, data1_handle, describes the state of the data1 system.
2826 This handle is passed as first argument to virtually all
2827 data1 related routines. The functions data1_create and data1_destroy
2828 creates and destroys a data1 handle respectively.
2830 Added ODR encode stream member to all backend request structures
2831 init, search, scan etc. This stream should be used to allocate all
2832 memory used for the response when thread safe operation is needed.
2834 Changed the comstack utility, cs_addstr, to be thread safe. The
2835 returned hostname string returned by the function is now part the
2838 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2839 function. The cs_straddr takes a COMSTACK handle as argument, so this
2840 function must be used after cs_create and before bind/connect.
2841 This function is thread safe.
2843 Moved test server to 'ztest' directory - generic server code still
2844 in 'server' directory.
2846 Made prefix query (pquery.c) utility thread safe.
2848 Added new function modifier YAZ_EXPORT to 'export' public DLL
2849 functions when using windows (see include/yconfig.h).
2851 Added definitions to the OID database (util/oid.c) (RVDM).
2853 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2855 Added call to ccl_rpn_delete in client program.
2857 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2858 release of RPN structure.
2860 Added support for C++, headers uses extern "C" for public definitions.
2861 With input from RVDM.
2863 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2864 Thanks to Ronald van der Meer (RVDM).
2866 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2868 Added support for private extensions to the OID database
2869 (oid_setprivateoids()). Thanks to RVDM.
2871 Added optional, physical ANY (key replication)
2873 Fixed null-reference problem in GRS-1 output filter.
2875 Proximity operator added to Prefix Query Format (PQF).
2877 In test client command "base" accepts multiple databases.
2879 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2883 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2885 Smallish bug-fixes in the new encoders/decoders (explain).
2887 Bug fixed in DeleteRequest.
2889 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2891 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2893 Added SOIF syntax (using private OID for now) to retrieval module and client.
2895 Added Update extended service.
2897 Added SearchResult-1 additional info structure.
2899 Added optional CCL (ISO8777) interpreter as separate module. Available
2902 --- 1.2 1996/6/10 (1st anniversary release)
2904 Added Summary record syntax. Lightly tested.
2906 Added OPAC record syntax. Untested.
2908 Added ResourceReport service encoders/decoders. Untested.
2910 Fixed bug in z_Unit - wrong tagging on unitSystem.
2912 Fixed bug in the DiagRecs decoder.
2914 Added options for max PDU size and session timeout to frontend-server.
2916 Added documentation of query-language parsers and other supporting utilities.
2918 [frontend-server] Added Attribute set to the bend_scanrequest API.
2920 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2921 surrogate diagnostics were generated.
2923 [retrieval] Allow multiple local values for attribute.
2925 [retrieval] Allow multiple attributes per element in .abs files. index type.
2927 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2929 --- 1.1pl2 1996/4/10
2931 Minor changes, mostly specific to Zebra's requirements (retrieval)
2935 Repaired bug in frontend server when running multiple listening
2936 endpoints in dynamic mode.
2938 z_External() now won't break if a known, ASN.1 value comes encapsulated
2939 in an octet-string. The value will pass through unmodified in an Odr_oct.
2941 Added a bit of code to the demo client to decode & display
2942 ASN.1-structured records represented in the octet-aligned branch of
2943 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2945 Added z_ext_getentbyref() to the ASN module. Doc updated.
2947 * Completed the SCAN definition in the ASN module. This may break SCAN
2948 code based on older YAZ-versions at compile-time. The fix is easy -
2951 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2952 under the SCAN definition. Remember to initialize this, server-people.
2954 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2955 that this does not extend to ODR and ASN.
2957 Comstack allows insertion of established socket (primarily for
2958 inetd-operation of servers). Doc updated.
2960 Front-end server can now start from the inetd in TCP mode. Doc
2963 --- 1.0pl4 1996/1/24
2967 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2968 the rank and record number.
2970 Adjustments to the frontend server.
2972 Fixed diagnostic BER dumper. It ignored the file argument.
2976 Various changes to retrieval module.
2978 Changed the union discriminators of the protocol files from enums to
2979 ints paired with #defines.
2981 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2984 *Changed operator in the RPN structure to 'roperator', again to avoid a
2987 Fixed problems in Explain decoders/encoders.
2989 --- 1.0pl2 1995/12/6
2991 Memory bug in log module fixed.
2993 --- 1.0pl1 1995/12/5
2995 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2997 Bug in Explain DatabaseInfo module fixed.
2999 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3003 The shift to v1.0 signals that we now consider the *core* functionality
3004 of YAZ reasonably stable (the core being more or less equivalent to
3005 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3006 tested (Explain not at all - though that will happen soonish).
3008 Minor changes to code to support Windows port.
3010 Various minor changes after we're getting to use GRS-1 & co. more.
3012 Added Espec-1 format.
3014 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3015 of the protocol and it cannot be selected when encoding (maps into 'string'
3016 when decoding). Needed to talk to some servers.
3018 Demo client can request simple element set names.
3020 Added Diagnostic Format encoders/decoders.
3022 Added simple Close handling to frontend server (no hooks for resource
3023 reporting yet), and demonstration client.
3025 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3027 --- 1.0b3 1995/08/24
3029 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3030 handled incorrectly when records were requested in the searchResponse. This
3031 will only affect you if you use the frontend-server.
3033 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3034 Test-client will ask for and print GRS1. Ztest will return dummy records
3037 Added Explain encoders/decoders to the service-level API. Untested.
3039 Added Extended Services: Item Order encoders and decoders to the Service-
3040 level API. Untested. We could use a recent copy of the pertinent bits
3041 of the ILL protocol to add those bits.
3043 Added diagnostic format 1 encoders/decoders to the service-level API.
3046 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3047 odr_cons.c, which causes a more correct output.
3049 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3050 was always set to 0 when no records were requested in the searchRequest.
3052 * Added better external-handling. This shouldn't harm old code that
3053 *encodes* externals. It can break code that looks for a
3054 'single-ASN1-type' representation, since those types that are known
3055 are now decoded immediately. Look at the SUTRS sample code in
3056 seshigh.c and client.c. Documentation updated.
3058 Handling of structured records in bend_fetchresponse. Length -1 marks
3059 structured record, type is deduced from format field.
3061 --- 1.0b2 1995/06/27
3062 Fairly quick maintenance release to add SUTRS support.
3064 Fixed handling of SUTRS records in the demonstration client.
3066 * Added format field to the bend_fetchrequest and bend_fetchresponce
3067 structures of the backend API (frontend server). When the record is
3068 returned, the value of the format field is mapped to an OID. The
3069 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3070 of the record. The special value VAL_NONE in the bend_request means
3071 that no specific format was requested by the client. Documentation
3072 updated accordingly. Test server (ztest) will return a fixed dummy
3073 SUTRS record if your client requests SUTRS.
3075 Documentation updated accordingly.
3077 You can now set external libraries and RANLIB support in the top-level
3081 First public release.
