3 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
4 with a flag whether to substitute escape sequences or not.
8 Fix nmem_strsplit_escape to substitute escape char properly.
10 New option for zoomsh -e , which makes it abort on first error and
11 return process exit code to indicate success/failure.
13 YAZ options utility supports special option -- which makes all it treat
14 all following arguments as non-options.
18 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
19 searched if absolute filename is given.
21 Fix conv_xslt() error-reporting when stylesheet is not found.
22 (The value of fullpath is meaningless in this situation.)
26 Fix problem in CQL sort node creation: un-initialized memory.
28 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
29 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
30 CQL sortby depending on whether Type-1 or CQL is actually sent to the
33 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
34 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
36 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
37 will make it possible to use both single-character mask (#) and wildcard (?)
38 in CCL . Throw diagnostic for left truncation because that is not supported
43 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
44 cases using escapes (\-sequences) and masking.
46 PQF parse fix: A trailing backslash followed by end-of-string (\0)
47 would result in a read one byte beyond string.
49 rpn2ccl may use Z39.50 masking for terms (t=z).
51 ICU check fix. Don't include library -lCrun on Solaris, unless present.
53 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
54 not --cppflags (which seeems like an error in icu-config).
56 -- 4.2.12 2011/08/27 RPM package only
58 cql2ccl: fix conversion of terms: operator characters were not
61 -- 4.2.11 2011/08/25 RPM package only
63 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
64 CCL parser will map both # and ? to their regular expression
65 quivalents (. and .*).
67 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
68 of reserved CQL characters.
70 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
71 is, so that they are passed through.
75 ZOOM SRU mode: more aggressive re-connect.
77 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
78 made available as a utility function, declared in <yaz/logrpn.h>
80 rpn2cql_structure() supports proximity nodes (except that the Type-1
81 proximity node's "exclusion" binary is ignored, as there is no way to
82 express that in CQL). Fixes bug #4564.
86 Fix SEGV that could occur if set command of zoomsh was given without
89 Fix SEGV that could occur if unsupported transport was given for
90 COMSTACK - say https (when SSL was unavailable).
92 Build yaz-url on Windows too.
96 New utility to get web content. Header is url.h. A command line tool
97 yaz-url is part of the distribution and packages.
99 Fixes for SSL COMSTACK (when gnutls is in use).
101 New functions yaz_base64{encode,decode}. Header is base64.h.
105 ZOOM C includes HTTP response buffer as additional info if it fails
106 to decode the SRU response.
108 Make wrbuf_json_puts available.
112 zoom: throw diagnostic for invalid value for option "sru". Before a
113 bad SRU request was sent.
115 Adding new utility wrbuf_vp_puts.
117 Add cclxmlconfig.obj to win/makefile. It was missing completely.
121 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
122 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
123 redirect was used at the same time.
125 MARC line mode decoding: be less picky about length given - first
126 5 digits of header that is.
128 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
130 Changes to decoding of SRU records: a record with recordPacking=xml is
131 modified with a new root element <yaz_record> if the recordData contains
132 multiple children elements. This is to make the record XML parseable
135 RPN to SOLR conversion: encode special characters.
137 Generic Frontend Server: fix uinitialized member, stepSize.
141 Fix a bug in SRU decoding of records.. The database records stored
142 had un-initialized memory, but it would only be seen with yaz_record_render
143 and type_spec="ext" .
145 Fix a bug in ccl_qual_dup introduced in 4.2.3.
149 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
153 Add new utilities to convert from CQL to CCL . These utilities have
154 prefix cql_to_ccl defined in cql.h.
156 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
157 lead to memory heap corruptions when ICU utilities were in use.
161 Make compilation work without Libxml2.
163 yaz-client: remove redundant blanks in display of searchResult-1 term
168 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
169 resulting CQL node (tree) in a new node CQL_NODE_SORT.
171 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
172 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
173 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
174 Note that the CQL sortby spec is only converted when the GFS is already
175 converting from CQL to RPN (cql2rpn element).
177 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
178 specify whether to collapse delimitors or not. The existing nmem_strsplit
179 do collapse (collapse parameter = 1).
181 Windows installer: For NSIS, set InstallDir depending on x86/x64.
183 Rename internal func yaz_use_attribute_create. While non-static, this
184 function is not declared in a public header.
188 Add -lCrun when linking with ICU on Solaris.
190 More quicks character set conversions for OPAC records.
194 fix problem with record_render: records were converted (character set
195 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
199 SRU: add methods for handling DADS SRU-proxy facets.
201 Separate OPAC record character set for ZOOM_record. yaz_record_render
202 allows a character set given as charset=from/opacfrom,to where 'from' is
203 the character set of a bibliographic record, 'opacfrom' is character set
204 of OPAC record and 'to' is the target character set.
208 yaz-client: show may XML format records. Command show followed by 'format'
209 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
212 src/stemmer.c: Avoid using unnamed union. It is not supported by some
215 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
218 Update yaz.spec to operate on both SLES11 / Centos 5.5.
220 RPM: Release includes 'indexdata' name. Use indexdata in release name so
221 this package can be distinguished from other vendors.
223 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
224 as determined by configure
226 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
228 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
229 returns no error and no record, the present request is considered
230 partial (only a subset of the records could be returned by backend), and
231 so it is appropriate to set Present Status to partial-4.
235 Move yaz-config man pages to section 1.
237 More documentation about SOLR.
239 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
240 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
241 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
242 peers on some Linux systems. However, in general that does not work
243 so YAZ can not rely on that to work. Debian changed behavior in this
244 respect from Debian lenny to Debian squeeze (still testing as of Oct
246 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
248 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
252 Fix yaz-config output: echo_source not set correctly by configure.
256 SOLR WebService support for yaz-client and ZOOM.
258 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
260 --- 4.0.12 2010/08/17
262 Z39.50 facet support. Facet specifications are passed for search in
263 other-information with ASN.1 as defined in facet.asn and OID
264 .10.1000.81.5 . Facets are expressed as an Attribute list as known
265 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
266 3 is limit (number of entries to get in response). yaz-ztest returns
267 dummy facets if a client asks for them.
269 --- 4.0.11 2010/07/09
271 CCL fixes: bug 2895 and bug 3539.
273 GR1-display: add comma in display - was removed by mistake in
276 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
278 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
280 --- 4.0.10 2010/06/18
282 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
283 result set from a connection. The result set will be on its own
284 thereafter; no operations on it will perform retrievals from a target.
285 Only cached copies are returned.
287 ZOOM C:fix case for HTTP servers responding with Connection:close.
288 Ensure that if there is a current task it is resumed (like fetching
289 more records in a result set) . Bug #3484.
291 PQF parser: use odr_atoi for Odr_int (not atoi)
293 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
294 values that contain any non-digits are treated as string attributes
295 (previously decoding only checked for leading character ([0-9]). PQF
296 encoding: attribute string values are not surrounded by double-quotes.
300 New utility for managing threads - thread_create.h.
302 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
303 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
304 but YAZ' implementation do.
306 Fixes for yaz_cond-functions on Windows 7.
308 DLL export more symbols.
310 zoomsh: show record do NOT render opac.
312 Remove *.la files from Debian and RPM packages.
316 Debian package libyaz-dev depends on libgnutls-dev again (was
317 removed in YAZ 4.0.6, but due to Libtool it is still needed
318 even though yaz-config do not list libgnutls libs).
320 ZOOM: Use only one WRBUF for returning string results for
321 ZOOM_resultset. Reduces memory usage for ZOOM in general.
323 ZOOM: ZOOM_connection do not use a shared pointer to
324 ZOOM_resultset after ZOOM_resultset is destructed by
325 user. Reverts to YAZ 4.0.4 behavior.
329 record-conv: fix problem with at least one XSL conversion -
330 due to probably incorrect usage of XML XSL documents.
334 Fix yaz-config for static mode and the use of SSL (gnutls).
338 Forward decl timeval struct in mutex.h and gettimeofday.h.
340 yaz-config: fix 'static' mode linking.
344 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
345 are wrappers for pthreads or Windows. For Windows these are put in
346 a separate DLL: yaz_cond4.
348 libyaz.la (whole source) is compiled with thread. If thread support
349 is enabled enabled, all source of YAZ is compiled with treading support.
350 This allows core utilities such as yaz_log to use thread facilities.
351 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
352 thread utilities. This commit moves mutex utilities (mutex.c) from
353 libyaz_server.la to libyaz.la.
355 yaz-json-parse displays leading text until error.
359 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
360 patch from Giannis Kosmas.
362 SRU: no longer URL encode SRU database. The URL for an SRU server is
363 a URL and such is alreeady encoded - at least when given with leading
364 http:// or https://. This reverts behavior to YAZ 3.0.50.
366 Support for new MARC XML notation TurboMARC which like MARCXML is a
367 complete representation of MARC/ISO2709.. This one, however, is more
368 compact and allows for faster processing with XSLT. TurboMARC can be
369 used in the marcdisp.h API, from the yaz-marcdump utility and from
372 yaz-ztest can be configured - via the database - to perform certain
373 delays when it performs operations search, present and single record
374 fetch. This allows testers to make yaz-ztest act as a real or even slow
375 Z39.50 server. Refer to the yaz-ztest man pages for details.
379 wrbuf_destroy allows NULL WRBUF passed to it.
381 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
383 Add ZOOM_connection_close.
385 No fixed size buffers for ZOOM shell - bug #3257.
387 tstodr: make it work on s390 platform.
389 New icu iterator-functions. The new icu_iter-functions makes it possible
390 to use ICU chains from many threads.
392 yaz-client: better syntax check for show command.
396 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
399 New simple local-file XML include facility which allows file glob-patterns.
400 Refer to yaz/xml_include.h.
402 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
405 ZOOM_record_get supports new parameter "format" which makes it format XML
408 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
409 JSONText in ECMA-262) is JSONValue, not JSONObject.
413 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
414 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
416 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
417 POSIX/Unix builds .so with major version 4.
419 Remove old LOG_-defines from log.h. They have been obsolete and
420 undefined by default for the last 5 years.
422 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
424 GFS: Remove socket (int *fd) from search_rr handler. The socket
425 descriptor ptr is a facility that allowed a search handler to supply
426 a socket which would serve as a callback - when search was complete.
427 This facility has now been in use for years.
429 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
430 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
431 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
432 returns 'const char *' rather than 'char *. The returned string is
433 read-only and should not be modified by applications. COMSTACK cs_close is
434 now a void function - it no longer returns int. No applications check for
435 the value and the implementations has always returned 0.
437 ZOOM: use size_t for scan hit counts and str size. Functions
438 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
439 occ (hit count) and len (string length) are now of type size_t pointer
440 rather than int pointer. This is to be able to represent large hit counts
441 and to also just to use the proper type for string length (strlen result).
443 New JSON parser. Refer to include/yaz/json.h .
445 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
446 Used to be int in some cases. Many wrbuf_-functions used to return an int
447 indicating some length.. These return values were never used. And so they
450 ODR: odr_malloc, odr_total now takes size_t for size.
452 clone_z_type: fix leak; occurred for encoding failures.
454 --- 3.0.52 2009/12/03
456 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
457 bug was introduced in 3.0.51.
459 --- 3.0.51 2009/12/02
461 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
463 tcpip comstack: fix leak for getaddrinfo.
465 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
466 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
467 Decoding of SRU "path" database is performed by private function
468 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
469 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
471 yaz-client: honor base command for SRU. Change when database setting
472 is applied for SRU and ensure it is kept when a connection is reset.
473 Change also the way errors are displayed or SRU (decoding of packages).
475 --- 3.0.50 2009/11/02
477 Add support for extra request / response data for SRU codecs and GFS.
478 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
479 for extra data response buffer and length. For the GFS, both request
480 and response data (XML) is carried in extra_args and extra_response_data
481 for the search handler. Patch by Ko van der Sloot.
483 ZOOM: For queries that cannot be converted to the specified rpnCharset,
484 ZOOM now returns a diagnostic on the client-side ('invalid query' /
485 10010). This fixes bug #2113.
487 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
488 cmdfile included a 'quit' command that would result in a memory violation.
490 --- 3.0.49 2009/10/01
492 Make a number of functions defined in xmlquery.c static. These have
493 never been declared in a public header file (yaz/xmlquery.h) and was
494 made public by mistake.
496 Improve speed of character conversions (iconv utilities). This makes
497 conversions from MARC-8 faster.
499 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
500 unless type desired is "raw". This will prevent type "xml" from
501 returning ISO2709 .. Which obviously can not be XML parsed.
503 Fix memory leak in ZOOM that would occur if option apdulog was used
504 on a re-used connection.
506 Frontend server logs HTTP requests.
508 Frontend server now sends Z39.50 close when it times out (sesssion has
509 been idle for too long). Versions 2.0.30 and earlier also sent close.
510 But due to a mistake this was disabled in all versions after that, i.e.
511 the server would just close the socket immediately.
513 yaz-client emits a better message when receiving an unrecognised
514 userInformationField.
516 Skip zero-length subfields when decoding ISO2709. This rare case happens
517 if a record has two FS characters in a sequence. Without this patch
518 there would be a reference beyond char array in using_code_len fragments
521 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
523 --- 3.0.48 2009/08/28
525 The show command offered by the zoomsh command now takes a 3d optional
526 parameter type which is what is passed to ZOOM_record. If the type
527 argument is omitted, "render" is used.
529 RPN to CQL conv may use USE string attributes (bug #2978).
531 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
533 --- 3.0.47 2009/07/08
535 Function yaz_xml2query allows a diagnostic element in the PQF XML
536 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
537 code and additional info respectively.
539 The BER BOOLEAN is now the integral type Odr_bool which still happens
540 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
541 typedef'd to Odr_int. This is still an integral 'int', but it may be
542 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
543 ASN-1 compiler as well as programs has been updated to use the new types.
545 --- 3.0.46 2009/06/08
547 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
548 only the bibliographic record was rendered. For type=opac, an OPAC
549 record is only returned if it is present.
551 iconv: small fix for encoding of advancegreek.
553 yaz-client: avoid double display of SRU/SRW records (bug #2798).
555 yaz-client: option auto_reconnect=on really reconnects.
557 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
559 server: avoid null ptr ref for for yaz_poll errors.
561 build: fix RPM build for RHEL 5.3.
563 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
565 --- 3.0.45 2009/03/31
567 Fixed bug #2709: TCP connect returns Invalid argument.
569 Fixed compilation for mingw.
571 Honor charset for raw records (ZOOM_record_get).
573 Fixed use of errno for threaded mode that was seen on Solaris 10.
575 Fixed argument passing with blanks in value for Windows Service.
577 Disable YAZ' own log rotate by default (no 1 GB limit).
578 The variable l_max_size which specifies the log file limit is set to 0
579 (DISABLED): This is due to the fact that YAZ is most often deployed using
580 logrotate. Also YAZ can not perform log rotate because of unsufficient
581 permissions (setuid).
583 --- 3.0.44 2009/02/17
585 List supported encodings in man page for yaz-iconv.
587 Fixed missing SSL libs for --libs output
589 Re-established OID record syntax application-xml. Nobody should use it
590 but we don't want to change soname because of this symbol being absent.
592 --- 3.0.42 2009/02/02
594 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
596 Added member named_result_sets for init handler struct for the GFS. This
597 allows a server to disable named result sets.
599 Removed OID record syntax application-xml.
601 Added support for rule-based transliterator for ICU wrapper of YAZ.
603 Fixed bug #1902: yaz-icu XML output.
605 Make YAZ checks Emacs friendly.
607 BITSTRING value shows value. Bug #2346.
609 ISO2709 decoding: skip control characters from indicator data.
611 Omit sort key by default in yaz-icu's output.
613 Allow combined single char options (again) for YAZ' options function.
615 Utility yaz-marcdump got option to display YAZ version (-V).
617 Allow YAZ to use ICU 3.4.
619 Added new ICU test case which illustrates removal of diacritics.
621 --- 3.0.41 2008/12/29
623 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
625 --- 3.0.40 2008/12/29
627 For configure, using option --without-xml2 also disables Libxslt/Libexslt
630 Fixed bug #2352: yaz-marcdump crashes for certain record.
632 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
634 Added support for Danmarc2 to UTF-8 conversion.
636 Added support for ISO5426 to UTF-8 conversion.
638 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
639 implementation version.
641 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
643 --- 3.0.38 2008/11/10
645 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
646 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
648 ZOOM C now interprets databaseName option for ZOOM connection as path
651 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
653 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
655 Dummy Libxml2 types no longer defined in headers of YAZ'.
657 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
660 --- 3.0.36 2008/09/26
662 Various ODR chapter fixes.
664 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
666 Added missing source for Windows compilation, mutex.c.
668 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
670 For SRU connections in ZOOM all records up to "count" are now fetched.
672 Fixed crash in generic frontend server (and yaz-ztest) which occurred
673 in Windows due to bad error handling for Libxml2.
675 Added facility for sending arbitrary records (ASN.1 any) using
676 ZOOM C's Extended service update. Patch by Sam Reynolds.
678 New options for ZOOM C's connection, logapdu which makes ZOOM log
681 --- 3.0.34 2008/06/18
683 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
685 --- 3.0.32 2008/06/12
687 Fixed memory violation that could occur when decoding UTF-8. This bug
688 was only present in 3.0.30 of YAZ.
690 --- 3.0.30 2008/06/06
692 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
693 GNU TLS is used by default (if found).
695 yaz-ztest returns OPAC records if a client asks for OPAC.
697 Improved speed of MARC-8 encoding.
699 Added support for lossy and loss-less MARC-8 encoding.
701 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
703 Added new Windows Service wrapper (sc).
705 yaz-client's itemorder command may now send a file.
707 Fixed yaz-marcdump to allow the use of NS prefix for record element.
709 Added new function yaz_log_xml_errors.
711 Allow (but warn) unknown XML attributes in MARCXML parsing.
713 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
715 The UTF-8 to MARC-8 conversion now uses a different set of characters
716 for Greek symbols. Bug #2120.
718 --- 3.0.26 2008/02/21
720 Added yaz_daemon (daemon.h).
722 Fixed bug #2068: pkg-config trouble
724 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
726 --- 3.0.24 2008/01/28
728 Document --with-xml2 option.
730 Added OPAC XML XSD (etc/opacxml.xsd).
732 Allow glob mask for name attribute in retrieval element for the
733 generic frontend server's retrieval facility.
735 Changed yaz_poll_poll to return yaz_poll_except for all returned events
736 except POLLIN/POLLOUT.
738 Fixed error handling in cs_listen. Bug #2037.
740 --- 3.0.22 2008/01/20
742 Fixed version in yaz/yaz-version.h.
744 Fixed bug #2027: Crash when closing connection.
746 Changed configure so that ICU support is only enabled if only ICU
747 and Libxml2 is available (because the ICU chain is XML based).
749 --- 3.0.20 2008/01/15
751 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
752 is built. Only this DLL depends on the ICU runtime.
754 yaz-ziffy is no longer part of YAZ. It is distributed separately by
755 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
757 Changed license of CCL module to 'Revised BSD'. After consultation with
758 remaining members of the original EUROPAGATE consortium, we are re-issuing
759 the CCL module without a separate license. The software was developed by
760 Index Data as part of a research project. The special license was included
761 to help feed usage information back to the project consortium to support
762 project evaluation. At this time, the project consortium has long-since
763 disbanded, and the majority of the original principals have retired. At the
764 same time, we have significantly modified the software during the following
765 years, to the point where very practically no original code remains. To
766 simplify re-use of the software, we have contacted those members of the
767 consortium who could be reached, and agreed to re-issue the module as a
768 proper part of the YAZ package.
770 Tcl scripts uses /usr/bin/tclsh as preferred shell.
772 CQL closer to being version 1.2 compliant. CQL also allows free-form
773 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
776 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
777 bug could make Extended services handling crash in the ZOOM layer. This
778 bug was only present in YAZ 3.0.18.
780 --- 3.0.18 2007/12/19
782 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
785 yaz-marcdump reads and writes collection wrapped records.
787 Handle OPAC for record conversion module.
789 Fixes for ICU wrapper.
791 Allow ICU libs to be controlled with --with-icu .
793 --- 3.0.16 2007/11/12
795 Added yaz_poll which is a wrapper for select/poll. When poll is available
796 and non-buggy, it is used, by yaz_poll . This allows more than 1024
797 sockets to be in use.
799 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
800 functionality through an XML based configuration (ICU chain). This system
801 is useful for search facilities such as Pazpar2 and Zebra that needs to
802 perform tokenization of indexed material. The ICU code in a separate
803 library libyaz3_icu.a.
805 Added HTTP tunnel facility for COMSTACK, bug #1752.
806 This is a facility that allows a Web proxy, such as squid, to tunnel
807 Z39.50 traffic. This facility is "transparent" to must applications
808 using YAZ. It's enabled by using pseudo transport connect: followed by
809 the proxy address, followed by command, then follwed by he regular
810 "virtual" addresss. For example,
811 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
813 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
815 --- 3.0.14 2007/09/21
817 Fixed bad memory reference in ZOOM_record - cuased by member not being
818 initialized. This was a problem only in YAZ 3.0.12.
820 Fixed bug in conversion from MARC to XML: Non-XML characters in control
821 fields were not removed.
823 Changed the way C code is generated from codetables.xml. Made a MARC-8
824 conversion trie for each characterSet section rather than codeTable.
825 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
826 of codetables.xml from Larry Dixson, LOC. Bug #1464.
828 --- 3.0.12 2007/09/12
830 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
831 from ZOOM_record_error).
833 ZOOM C function ZOOM_record_get returns record schema for type="schema".
835 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
837 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
839 Better SRW-to-Bib-1 diagnostic mapping.
841 ZOOM C and yaz-client announces SRU version 1.2 by default.
843 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
846 Fixed in yaz_sru_decode to allow other version than 1.1.
848 --- 3.0.10 2007/08/22
850 Added support for SRU scan for ZOOM.
852 Added support for the use of the older versions or Extended Service
853 Update in ZOOM. To faciliate this, an option "updateVersion" may be
854 set to the version , 1=first, 2=second, 3=third. The third version is
855 what ZOOM C has used so far. And that, obviously, is the default.
857 Added support for CCL queries in Z39.50 queries sent to the GFS (and
858 therefore in Zebra and in SimpleServer-based applications). The new
859 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
860 qualifier file used to transform incoming CCL queries into Type-1 RPN,
861 which is passed into the back-end search callback function.
863 Added support for HTTP Basic authentication in clients: the SRU/W
864 codec encodes the username/password elements of the PDU structure
865 appropriately, and these may be set using the "user" and "password"
866 options in ZOOM-C applications (the same options that are used for
867 Z39.50 authentication).
871 Fixed bug #1208: SSL appears to be broken in ZOOM.
873 Fixed bug #1206: Libxml2 include path weirdness.
875 Added oid_name_to_dotstring.
877 Allow elementSetName to be specified for ZOOM C record update.
879 Allow waitAction to be specified for ZOOM C based for Extended Services.
881 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
882 syntax OID. Bug introduced in YAZ 3 series.
884 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
888 Fixed bug #1157: yaz-client does not read .yazclientrc from current
889 directory. yaz-client now reads commands from file given by option -f
890 if specified; then tries to read .yazclientrc in current directory.
891 Failing that, it reads .yazclientrc from user's home directory.
893 Added support for correlationInfo Note and ID for Record Update via
896 Added yaz-client command querycharset which specifies character set for
897 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
898 (termListAndStartPoint).
900 Charset ISO5428:1984 is an alias for ISO5428-1984.
902 Implemented a way to perform scan in a result set using Z39.50. This
903 is achieved by attaching the result set name in the characterInfo
904 (type InternationalString) of OtherInformation in the Scan Request PDU.
905 The result set is identified in the otherinformation by the new OID:
906 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
907 This allows for scan in result set and faceted search . Zebra did some
908 of this in the APT term using attribute type 8 and value being result
909 set. Using the OtherInformation approach for this is cleaner and easier
910 to work with in proxies and the like. This facility can be used in
911 yaz-client using new command setscan which takes a result set as first
912 argument, start position (APT) as second.
914 Changed decoding of SRU XML packed records to deal with servers that
915 have recordData with XML data with multiple root nodes. Also make
916 comparison for recordPacking case insensitive. Again, one server
917 returns "XML" where others return "xml".
919 For SRU responses allow Content-Type application/xml as well as text/xml.
923 Fixed bug in character set conversion of BER strings. Bug introduced
928 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
930 For OID class, use oid_class consistently.
932 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
935 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
936 character set for bibliographic information interchange". By Giannis Kosmas.
938 Added documentation on new OID API.
942 Changes to generic frontend server interface: added new member
943 'query_charset' for bend_initrequest structure. A backend init handler
944 should set this member to its native character set for query terms.
945 When defined, the frontend server logic will announce this character set
946 to a client if the negotiationModel bit is set by the client. All server
947 implementors are encouraged to specify this. If a backend server does not
948 specify this a warning is issued using yaz_log(YLOG_WARN,..).
950 Added CCL utility to remove terms (stop words) from resulting RPN
951 tree. This is handled by functions with prefix ccl_stop_words_ .
953 New ZOOM C option, "rpnCharset", which allows client-side conversion of
954 terms in RPN queries.
956 Clean-up the CCL API. Moved some internal structures from ccl.h to
957 private header cclp.h. Changed ccl_parser_create so that a Bibset must
958 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
959 This is replaced by ccl_parser_find_str which takes a string instead.
961 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
962 libyaz.la is the core of YAZ except the generic frontend server and
963 does not depend on POSIX threads anymore. libyaz_server.la is the
964 generic frontend server facilities and uses POSIX thread functionality
965 if available. The libyaz.la no longer depends on POSIX threads because
966 the number of global structures is limited. NMEM no longer re-uses blocks
967 between threads ; it simply free's memory immediately but allocates in
968 "large" chunks as usual. We don't expect any performance penalties
969 because of this. The yaz_log system is still using a global log_level so
970 caution must be taken when modifying it with yaz_log_init_.. +
971 yaz_log_mask_str. This, however, should not cause any trouble because
972 these functions are called during initialization of application code
973 anyway. `yaz-config --libs server` returns libs for server applications;
974 `yaz-config --libs` returns libs for non-server applications.
976 New OID database - with public definitions in oid_db.h. Removed old OID
977 database including the head oid.h and definitions such as enum oid_value
978 and struct oident. The new OID database uses the same string names as
979 before but the 'protocol' is gone. There are now only two representations
980 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
981 converts from string to OID; functions with prefix yaz_oid_to_string
982 converts the other way.
984 Change to emit_term() in CQL-to-PQF query translation: when a term has
985 the /regexp relation modifier, do not process it for leading and
986 trailing "^" and "*", which have quite different meanings in regular
989 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
990 write handlers no longer carries a 'last' parameter. This will make
991 yaz_iconv flush "less" characters. A flush is performed by call to
992 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
994 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
995 removed, because function yaz_query_to_wrbuf does the same.
997 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
998 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1000 Deprecated MARC utility functions removed.
1002 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1005 Branch split: YAZ_2_1_55_branch
1007 --- 2.1.54 2007/03/16
1009 Fix to ZOOM-C so that transparent reconnection is properly handled on
1010 connections that are in asynchronous mode.
1012 Fixed compilation on OpenBSD 4.0.
1014 Large strings in GRS-1 records are now properly displayed in yaz-client.
1016 Added character conversion support for "advancegreek"; based on patch from
1019 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1020 sequence is met. Before the error was not set so it would be unknown.
1022 Adjust yaz-marcdump MARC reader so that it skips until record separator
1025 --- 2.1.52 2007/03/07
1027 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1028 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1029 fd_set structure used as a bitmask for the FDs to be selected on.
1031 Using ACX_PTHREAD macro to check for POSIX threads.
1033 Fixed have-vsnprintf check.
1035 --- 2.1.50 2007/02/23
1037 Fixes for configure on BSD. Bug #900.
1039 Added snprintf/vsnprintf wrappers for systems that don't have
1040 limits (heavens forbid).
1042 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1043 created before all previous tasks were completed and removed from the
1044 task queue, the new task could be removed by a mistake.
1046 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1048 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1050 Fixed bug #832: Problem with MARC/charset in yaz-client.
1052 Fixed bug #668: save command line history for yaz-client.
1054 Fixed bug #830: pkg-config support.
1056 --- 2.1.48 2007/01/23
1058 Extended ZOOM result set options with two options that may be read by
1059 a client: resultSetStatus and presentStatus with values as specified for
1061 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1063 Fixed bug #827: Using SSL fails on Debian etch.
1065 Fixed bug #826: Weird looking chars for set of MARC records.
1067 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1068 that is treated as an ItemOrder with itemRequest being an XML document
1069 external. The value of "doc" is the content.
1071 Extended the GFS search facility. New member of bend_search_rr
1072 'estimated_hit_count' signals that hits is known to be an estmate
1073 (higher or lower than real hit count). New member 'partial_resultset'
1074 signals that the search was partial (hit count is lower or equal than
1075 real hit count). For Z39.50, the information is stored in resultSetStatus
1076 member of SearchResponse APDU. For SRU, the information is signalled
1077 via SRU diagnostic 59: "Result set created with valid partial results
1080 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1082 --- 2.1.46 2007/01/13
1084 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1086 Added ZOOM_connection_peek_event.
1088 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1089 the following new functions:
1090 ZOOM_event_nonblock, ZOOM_connection_process,
1091 ZOOM_connection_get_{socket,mask,timeout},
1092 ZOOM_connection_fire_event_{timeout,socket}.
1093 The existing blocking event handler, ZOOM_event, is a wrapper for the
1094 + blocking ZOOM_event_sys_{poll,select}.
1096 Implemented function ccl_xml_config which parses XML version of CCL
1097 configuration (bug #798).
1099 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1101 Added timings utility (yaz/timing.h)
1103 --- 2.1.44 2007/01/03
1105 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1108 Fixed bug #779: Rotation of apdu.log fails.
1110 Fixed for character set conversions:
1111 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1112 Honor G1 set in MARC-8 decoding.
1114 --- 2.1.42 2006/12/17
1116 Fixed bug #775: char conversion does not handle Alternative UTF-8
1119 Implemented function yaz_marc_read_line which parses MARC line format
1120 records. There is a wealth of formats out there. So far, this function
1121 reads line records produced by yaz_marc_write_line.
1123 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1124 more generic and easier to remember(!) options: -i format and -o format
1125 which specifies input format and output format respectively - where
1126 format is one of "marc", "marcxml", "line", "marcxchange".
1128 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1129 does not print anything except warnings for records.
1131 For yaz-marcdump, added support for MARC split into files (-s) with a given
1134 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1135 spec, at http://www.loc.gov/standards/sru/record-update/
1136 This has changed the binary layout of the following structs:
1137 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1138 bend_update_rr . Patch by Ko van der Sloot.
1140 Added GFS utility function bend_assoc_is_alive which returns 1 if
1141 association is still alive (client is connected); 0 otherwise (client
1142 closed connection). This allows busy servers to stop working for
1145 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1146 been a separate piece of software. This version of ziffy has been modified
1147 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1149 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1151 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1152 Client code may now interrogate options such as "init_opt_sort" to
1153 find out whether the server claims to support various options.
1155 --- 2.1.40 2006/11/27
1157 Added utilities yaz_{set,get}_esn to set/get element set name from
1160 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1161 of YAZ and has been so since YAZ 2.1.10.
1163 Implemented ZOOM_record_error which returns error information for
1164 record (surrogate diagnostic).
1166 --- 2.1.38 2006/10/31
1168 Updates for SRU Update by Ko van der Sloot:
1169 1. Changed name from "operation" to "action"
1170 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1171 versions in the code, marked as 'backward compatible'.
1172 3. Added diagnostics for SRU Update.
1174 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1176 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1178 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1180 For GFS, fixed problem with SRU diagnostic 'First record position out of
1181 range' being issued for 0 hits.
1183 zoomtst10 part of Windows Build.
1185 --- 2.1.36 2006/10/13
1187 Implemented yaz_filepath_comp which splits a path into file path
1188 components (required by Zebra 2.0.3+).
1190 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1191 BSD inspired license until now so this should not have any real impact on
1192 anybody. See http://www.opensource.org/licenses/bsd-license.php
1194 Fixed bug #687: Missing log lines.
1196 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1199 Fixed bug #689: SRU diagnostics to be added.
1201 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1202 whether a connection is idle (no more work do do).
1204 --- 2.1.34 2006/10/04
1206 Change type of optval from long to int for invocation of setsockopt with
1207 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1209 Added support for specifying the max log file size for the Generic
1210 Frontend Server. The size is given with option -r.
1212 --- 2.1.32 2006/09/21
1214 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1216 --- 2.1.30 2006/09/17
1218 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1221 Fixed bug in Generic Frontend Server that could cause a server to stop
1222 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1224 For the generic frontend server, the maximum record size is used as maximum
1225 size of incoming packages (SRU + Z39.50). The value until was previously
1226 only used in Z39.50 Init negotiation and, later, in a session controlled
1227 sizes of records returned. This is controlled using -k option. It can be
1228 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1230 --- 2.1.28 2006/09/04
1232 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1235 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1237 New option for yaz-marcdump -lpos=value which allows setting a portion
1238 of MARC header to a certain value.
1240 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1242 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1243 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1245 --- 2.1.26 2006/08/15
1247 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1250 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1252 --- 2.1.24 2006/08/08
1254 Fixed MARC ISO2709 encoding routines to deal with character set
1257 Minor changes to GFS logging. Database included in search request log
1260 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1261 cached/multiple records.
1263 Shared libraries are built by default on Unix+configure.
1265 Changed cql2pqf transformation to use a different evaluation order. The
1266 new order is: always, relation, structure, position, truncation, index
1267 and relationModifier. Old order was: always, relation, relationModifier,
1268 structure, index, position, truncation. Note that the the latter ones
1269 override former ones for identical attributes.. The new scheme means that
1270 it is possible to override any existing attribute with a relationModifier.
1271 And also that it is possible to override everything for the index rule
1272 (except the ones listed in relationModifier). No order is perfect but this
1273 one, we believe, covers more real cases.. The "always" should have been
1274 called "default", since the attributes there can be overridden with all
1277 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1278 compilation phase, but also for yaz-config --cflags output. This allows
1279 us to have public headers with Libxml2 stuff in them . It should also,
1280 eventually, make Libxml2 checks redundant in packages using YAZ, such
1283 --- 2.1.22 2006/06/15
1285 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1286 stored in uri, message and details.. Previously diagnostics were stored
1287 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1288 compatibility.. but he's probably the only one affected, so.
1290 Added support for CCL, compiled on the client side, in ZOOM-C. This
1291 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1292 input; the resulting query objects can be used for for searching with
1293 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1295 YAZ' configure searches for OpenSSL by default.
1297 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1298 SL_CTX_use_certificate_file. See
1299 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1300 for more info. Thanks to Ko van der Sloot.
1302 --- 2.1.20 2006/06/02
1304 Bug #600: SRU GET, POST support for yaz-client. Introduced
1305 command 'sru' which selects method SOAP/GET/POST.
1307 Allow missingValueAction to be specified for the sortspec string -
1308 function yaz_sort_spec. By default, the missing value action is null.
1309 Use ! to specify "abort". Use = followed by stringvalue to specify default
1312 Ensured that Present-handler (if defined) is called in GFS before any call to
1313 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1314 searchRetrieve requests.
1316 Documentation for YAZ is now based on the Docbook XML/XSLT using
1317 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1318 is no longer depending on jade/openjade or docbook-to-man scripts.
1319 PDF is no longer part of the distribution - but can optionally be
1320 made using DSSSL/jadetex or FOP.
1322 Added retrieval handling support in Generic Frontend Server to support
1323 conversion between MARC/XML as well as XSLTtransforms. See
1324 etc/yazgfs.xml for an example.
1326 Added Authentication support to Generic Frontend Server in SRU
1327 mode. Authentication using HTTP Basic is supported, as is the use
1328 of 'x-username' and 'x-password' parameters in the request itself.
1330 Added support for a new character set MARC8s identical to MARC8 except
1331 that it converts combined characters to single Unicode characters in the
1332 Latin-1 range (when possible).
1334 --- 2.1.18 2006/04/24
1336 ASN.1 compiler 0.4: generates brief Doxygen file header for
1337 generated .h/.c files.
1339 Utility yaz_iconv now supports conversion to MARC-8.
1341 New facilities for the MARC module. The reading - and writing of
1342 content are separate methods for the yaz_marc_t handle. The following
1343 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1344 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1345 format). Write functions have prefix yaz_marc_write_.. The existing
1346 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1347 available. Removed support for OAI-MARC and simplexml (not the
1348 simplexml from PHP5).
1350 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1351 to be returned for this connection.
1353 --- 2.1.16 2006/03/31
1355 Allow multiple languages and charsets to be specified with
1356 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1357 negcharset iso-8859-1,utf-8
1359 Translation of proximity nodes from CQL into PQF now works.
1361 Moved to automake 1.8, 1.9.
1363 Added function yaz_log_set_handler which allows a log handler to be
1364 installed. This handler will be called for all log messages. Output
1365 to file is also produced; but that can be disabled by passing NULL
1366 fname to yaz_log_init_file.
1368 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1370 For SRW (including GFS), accept application/soap+xml as content-type
1373 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1374 produces NO stylesheet reference even if a default stylesheet is specified
1377 --- 2.1.14 2006/03/14
1379 Updated Windows package to include yazd.dll + yazd.lib for the
1380 Development component.
1382 If the environment variable YAZ_LOG is set, then it is used as a
1383 string indicating the default level of logging to use if not
1384 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1385 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1386 used as before. So, for example, to omit warnings from YAZ logging,
1387 export YAZ_LOG=-warn
1389 cql_transform() now map structure and other attributes before indexes,
1390 so that index-specific structures and other attributes can override
1391 defaults. So now a combination of mapping specifications such as:
1393 index.dc.date = 1=date-modified 4=5
1394 does the right thing.
1396 cql_transform() now also respects the "always" mapping specification,
1397 which establishes an initial set of attributes to be used for all
1398 terms except where overridden by more specific attributes associated
1399 with the index, relation or modifier.
1401 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1402 which mode to use; one of "post", "get" or "soap" (SRW, default).
1404 Fixes for yaz_iconv routines: changed trie-based character set conversions
1405 to use only non-negative values for bit fields due to Sun's C compiler not
1406 supporting negative values.
1408 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1409 sequences where not read correctly. Fix by Rustam Usmanov.
1411 Updated win/makefile to use options, settings which makes things
1412 compile with VS C 2005.
1414 --- 2.1.12 2006/02/01
1416 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1418 In ZOOM socket code, use select instead of poll on MacOSX.
1420 ZOOM-C now support client-side compilation of CQL into RPN that is
1421 sent to the server, enabling CQL to be used against all Z39.50
1422 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1423 ZOOM_query object, and submit it using ZOOM_connection_search().
1424 The CQL-to-RPN translation uses a configuration file, the name of
1425 which must be specified in the Connection's "cqlfile" option.
1427 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1428 function, which takes as its start-term parameter a ZOOM_query object
1429 (which may have had either CQL or RPN set into it).
1432 --- 2.1.10 2005/11/29
1434 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1435 GFS to support this as well. Backend handler, bend_srw_update, does the
1436 update work. Code contributed by Ko van der Sloot.
1438 Allow retrieval of Search Result-1 information in ZOOM by the use of
1439 options that are attached to a result set. ZOOM documentation updated
1442 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1443 UTF-8 conversion. Patch by Raj Patel.
1445 Added option -m to GFS to control formatting of timestamps in log file.
1447 Added 'exit' as synonym for 'quit' in yaz-client
1449 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1450 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1451 for the new members. Patch by Ko van der Sloot.
1453 Added support for SRU POST. It is supported for content-type
1454 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1456 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1457 Instead make the library libyaz.la multi-threaded. Threading as a whole
1458 can still be disabled by configure option --disable-threads. Previosly,
1459 with older GLIBCs there were problems with MT libs under Apache. This
1460 has now been fixed a long time ago.
1462 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1465 CQL module modified to be case insensitive for relations/indexes/operations.
1467 Fixed bug in CQL transform code: incorrect value relationModifieder
1470 Added 'show all' command for yaz-client which retrieves all results
1473 Added new yaz-client, xmles, which takes a (private) OID and
1474 a document to be sent as an extended service request.
1476 Describe new yaz-client commands wait_response and set_auto_wait.
1478 Increase TCP/IP listener backlog from 3 (which I am guessing was
1479 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1480 that the socket will queue as many incoming connections as it's able
1481 to handle ongoing connections. In other words, it will never now
1482 refuse a connection that it would be able to handle merely because
1483 it's not got around to accepting() enough of the pending connections
1484 yet. This is the behaviour anyway under Linux, where the listen()
1485 argument is ignored; but not under BSD and on systems such as
1486 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1487 YAZ-based servers should now be uniform across operating systems in
1490 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1491 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1492 This allows yaz-marcdump to read large MARC batches (>2 GB).
1494 Modified all YAZ source files - except the source which is auto-generated
1495 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1498 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1499 corresponding to the existing *_setl() function. These allow option
1500 values containing arbitrary valuues.
1502 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1503 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1504 except that it returns an indicator of whether or not the sort
1505 criterion was accepted (0 for OK, -1 for invalid).
1507 --- 2.1.8 2005/06/07
1509 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1510 MARC output rather than returning "new" buffer.
1512 yaz-client warns about unknown init options.
1514 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1516 --- 2.1.6 2005/05/24
1518 Added support for SRW sort in Generic Frontend Server. Patch
1519 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1520 sortKeys - or NULL if none is provided.
1522 Fixed bug #307: It was impossible to specify indefinite/no timeout
1523 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1526 Added support for multiple languages and charsets to be specified in
1527 ZOOM. Each charset/language is separated by a blank. If negotiation is
1528 in effect in init-response, Option
1529 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1530 Code based on patch by Vasiliy Osadchuk.
1532 Fixed bug #306: infinite recursion that occurred when calling
1533 yaz_log_level_init as the first call (before other log level or
1536 Fixed bug in scan handling in front end server: if preferred-Position-In-
1537 Response was non-present, a NULL pointer referece was performed.
1539 --- 2.1.4 2005/04/26
1541 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1542 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1543 now defined for all those error codes. So instead of putting 109 in
1544 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1545 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1547 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1550 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1552 Program yaz-client now exits and produces an error message if multiple
1553 Z39.50 servers are specified on the command line (none or one allowed
1556 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1559 --- 2.1.2 2005/03/16
1561 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1563 Fixed bug #272: Preserve spacing for CCL terms.
1565 --- 2.1.0 2005/03/14
1567 Added support for virtual hosts and multiple backend servers for
1568 the YAZ frontend server. The configution is XML based and
1569 support specificition of CQL to RPN mappings and explain information.
1570 See section "Virtual Hosts" in the YAZ manual.
1572 Extended OPAC display utility. OPAC display utility renders
1573 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1574 to supplement yaz_marc_decode_wrbuf.
1576 Fixed a bug in MARC decoder that could caused it to crash for some
1577 invalid MARC records. More diagnostics and warnings where added in
1578 XML output (warnings, etc are stored in comments).
1580 --- 2.0.34 2005/02/08
1582 Fixes for UNIX domain sockets. Bug #261.
1584 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1586 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1587 Added yaz_marc_subfield_str which defines subfield lead string which is
1588 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1589 yaz_marc_endline_str which defines end of fields string used in
1590 YAZ_MARC_LINE format. Default string is newline.
1592 Experimental support for MarcXChange. This format can be produced
1593 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1594 http://www.bs.dk/standards/MarcXchange.xsd
1596 Added yaz-client commands scansize that sets maximum number of
1597 entries to be returned by scan.
1599 --- 2.0.32 2005/01/11
1601 Added support for SRW scan in yaz-client and Generic Frontend Server.
1603 * Added whereInList member to SRW Scan Term.
1605 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1607 Fixed NMEM system to return aligned blocks on the smallest boundaries
1608 that are suitably aligned for all possible types on the particular
1609 architecture YAZ is being built for.
1611 --- 2.0.30 2005/01/04
1613 Fixed numerious warnings that was issued with newer versions of GCC.
1615 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1616 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1619 Make YAZ Generic Frontend Server slightly faster.
1621 Enhance (and reduce) logging for Generic Frontend Server.
1623 Revert YAZ log system so that it flushes every write operation
1624 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1626 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1627 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1628 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1629 will effectively disable old definitions.
1631 --- 2.0.28 2004/11/09
1633 Added yaz_log_time_format which specifies log format using
1636 Added yaz_log_module_level which returns mask for a module. Value
1637 is non-zero mask a if module is enabled; zero if disabled.
1639 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1640 in include/yaz/cql.h.
1642 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1644 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1646 Fixed bug #172: RPM builds does not enable SSL.
1648 Doxyfile.in part of dist. Doxyfile generated by configure.
1650 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1651 are given and the corresponding component does not exist.
1653 Extend CCL documentation in YAZ reference. Describe r=r.
1655 --- 2.0.26 2004/10/01
1657 Fixed MARC->MARCXML conversion to properly deal with
1658 fields, subfields, indicators having non-ASCII characters.
1660 Fixed MARC->MARCXML conversion so that ASCII control characters
1661 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1664 Added YAZ GFS support for conversion from Z39.50 surrogate
1665 diagnostics to SRW surrogate diagnostics.
1667 Bug fix: YAZ GFS did not return schema in explainResponse.
1669 --- 2.0.25 2004/09/30
1671 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1672 now converts recordSchema to elementSetName as well as schema URI.
1674 Fixed bug in COMSTACK that prevented HTTP request packages from being
1677 --- 2.0.24 2004/09/29
1679 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1680 does not require white-space before and after the dash in a range, e.g.
1681 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1684 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1685 due to new GCC removing "redundant" code.
1687 Added yaz-client commands scanpos and scanstep that sets preferred
1688 position and step-size for scan.
1690 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1692 Added CCL utility ccl_qual_buf which parses one or more CCL
1693 spec lines in a buffer.
1695 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1696 of name and value - ignoring empty lines and comments.
1698 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1700 Added odr_get_element_path which returns current element path for an
1701 ODR handle. This utility is useful in error handling or user-defined
1704 Added ODR_PRINT utility odr_set_stream which is is a more generic
1705 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1706 to a write function and pointer to close function. The close function - if
1707 non-NULL - will be called during odr_destroy.
1709 Fixed bug in CCL parser where truncation char was not removed from
1710 right side when truncation=both was in effect.
1712 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1715 --- 2.0.23 2004/08/11
1717 Fix buffer overrun in CQL parser when dealing with proximity (%).
1719 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1720 to UTF-8/UCS conversion is now only based on codetables.xml.
1722 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1724 --- 2.0.22 2004/08/06
1726 Add support for more "commit changes" in ZOOM (uses Extended Services).
1728 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1731 Yet another small fix for configure of SSL.
1733 --- 2.0.21 2004/05/14
1735 Fix SSL libs for configure when --with-openssl=DIR is given.
1737 --- 2.0.20 2004/05/10
1739 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1741 SSL comstack now uses yaz.pem certificate file on server side
1742 by default. Certificate filename can be configured by calling
1743 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1745 Fix bug regarding multiple calls to ZOOM_connection_connect.
1747 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1749 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1750 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1752 ZOOM now allows inspection of X509 peer certificate for verification.
1753 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1755 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1756 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1757 as "modular" but it simplifies things.
1759 Added cs_get_peer_certificate to that returns peer X509 PEM.
1761 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1762 NULL if SSL is unavailable.
1764 Documentation about MARC decoding tools.
1766 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1768 --- 2.0.19 2004/03/30
1770 Rename CHANGELOG to NEWS to follow GNU style packing.
1772 Fix bug with missing initialization of member in init_diagnostics.
1773 This bug affects threaded version of GFS server.
1775 --- 2.0.18 2004/03/20
1777 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1780 Ensure zlib.dll is packed with Windows install.
1782 --- 2.0.17 2004/03/17
1784 Fix encoding of xsd:string to use text instead of CDATA.
1786 Fix endless loop in CQL parser with unbalanced ".
1788 Use a more compact way to store MARC-8 conversion tables.
1790 --- 2.0.16 2004/03/16 Debian only
1792 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1795 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1800 --- 2.0.15 2004/03/01
1802 Another fix for decoding of XML packed records.
1804 --- 2.0.14 2004/02/25
1806 Fixes for Chunked encoding. White space not ignored after length spec.
1808 Update NS and use default NS for SRW diagnostic elements.
1810 --- 2.0.13 2004/02/23
1812 Implement ZOOM_resultset_cache_reset which resets record cache.
1814 Implement ZOOM_resultset_sort which sorts a result set.
1816 Implement chunked HTTP transfer.
1818 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1820 --- 2.0.12 2004/02/16
1822 Added member 'schema' to bend_explain_rr structure so that backend
1823 can specify explain record identifier. Defaults to Zeerex 2.0.
1825 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1827 --- 2.0.11 2004/02/16
1829 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1832 Added init command for yaz-client which sends "extra" init request.
1834 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1835 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1837 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1839 Make ZOOM error code for "invalid query".
1841 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1843 --- 2.0.10 2004/02/05
1845 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1848 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1850 Added option -p <file> to make Generic Frontend Server to write PID file.
1852 Added option -D to put Generic Frontend Server in background on its own.
1854 Make ZOOM C recognize option "password". If unset, "pass" is used
1855 (for backwards compatibility).
1857 Fixed a bug in Generic Frontend Server that could make it crash if a
1858 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1861 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1862 Must be issued before open, in order to be in effect.
1864 --- 2.0.9-6 2004/01/12 Debian/Windows
1866 Make the SRU server more picky WRT unknown params, etc.
1868 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1870 New YAZ client command, options, that sets Z39.50 options.
1872 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1873 options from a string of tokens (one token for each option bit).
1875 Update SRW diagnostic code messages.
1877 --- 2.0.9-5 2004/01/07 Debian/Windows
1879 Handle user defined stylesheet for SRW/SRU.
1881 --- 2.0.9-4 2004/01/06 Debian/Windows
1883 Fix bug in decoding of Content-Length.
1885 --- 2.0.9-3 2004/01/06 Debian/Windows
1887 Fix a bug with decoding of XML packed records.
1889 --- 2.0.9-2 2004/01/05 Debian only
1891 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1893 Fix bug in SRW/SRU diagnostics decoding.
1895 --- 2.0.9 2004/01/05
1897 Fixed bug in Generic Frontend Server which could drop records exceeding
1898 preferred message size. Reported and fixed by Irina Dijour.
1900 Fixed calculation of package size for structured records in Generic
1901 Frontend Server. Reported and fixed by Irina Dijour.
1903 Fixed namespace for SRW/SRU diagnostics.
1905 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1907 --- 2.0.8 2003/12/22
1909 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1910 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1913 CQL changes to reflect recent changes to the specification:
1914 * Documentation talks about context sets instead of index sets.
1915 * Documentation talks about indexes instead of qualifiers.
1916 * The CQL-to-PQF transformer's configuration file now uses
1917 "index.set.name = <attributes>" instead of the old form
1918 "qualifier.set.name = <attributes>". (Both forms are still
1919 understood but the latter is deprecated.)
1920 * CQL terms with no explicit index specified are now interpreted as
1921 cql.serverChoice instead of srw.serverChoice (which of course
1922 behaves exactly the same.)
1924 --- 2.0.7 2003/12/16
1926 MARC conversion can now generate ISO2709 output in another
1927 character set. yaz-marcdump uses this facility if you invoke it
1930 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1931 functions from there can be used from C++.
1933 --- 2.0.6 2003/12/04
1935 Frontend server now transfers memory from decoded packages to stream
1938 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1939 references to show up.
1941 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1942 the ZOOM Abstract API. The older names for the same options are still
1943 also supported for the benefit of old applications.
1945 ZOOM-C supports "implementationId" and "implementationVersion" options
1946 to go along with "implementationName". These allow the user code to
1947 specify identification strings to be sent to servers.
1948 Add OID for the new ExtLite attribute set.
1950 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1951 as requested/supplid by Ere Maijala <ere@atp.fi>
1953 For generic frontend server, reverse the order of
1954 "toolkit-supplied / application-supplied" strings sent as implementationId,
1955 Name and Version. Also, remove the spaces around the slash. This brings
1956 the GFS in line with the behaviour of ZOOM-C on the client side.
1958 Add function ZOOM_scanset_display_term.
1960 yaz-client shows scan displayTerm if present.
1962 Utility yaz-iconv is now installed by default along with the man page
1965 Extend configure check for OpenSSL to use pkg-config where available (such
1968 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1969 server to specify uid/gid/mask for socket using the format
1970 unix:[user=uid,][group=gid,][umask=mask,]file=path
1971 If file= is omitted the existing format is assumed, e.g.
1973 in which case the mask is 0666 (rw for everybody).
1975 Major restructure of YAZ source. All source in libyaz is in src directory.
1976 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1977 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1979 Added man page for utility yaz-marcdump (used to be called marcdump).
1980 yaz-marcdump is installed by 'make install'.
1982 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1983 of incoming package failed.
1985 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1987 Change prototype of odr_perror: add const to message string.
1989 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1991 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1992 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1993 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1994 DNS lookup. There should not be any compatibility problems with this
1995 assuming that blocking=1 or 0 is used.
1997 Fix bad reference in UNIX comstack in function cs_addrstr.
1999 Fix for compilation on AIX.
2001 The generic front-end server (server/seshigh.c) now supports returning
2002 Init diagnostics to the client in User-information-field, in
2003 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2006 --- 2.0.4 2003/09/04
2008 Allow any CQL relation (not just all,any,exact,scr).
2010 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2011 that features the same UI.
2013 Implemented command update0 in YAZ client which is equivalent to
2014 update but uses old of Ext Update ASN.1.
2016 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2017 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2018 Previously no OID was used for this info.
2020 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2021 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2022 returns 'malformed search term' otherwise.
2024 SortResponse member resultCount now set to NULL in sort handler of
2027 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2030 Add three new utility functions for translating OIDs between various
2031 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2032 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2033 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2034 char *oid_to_dotstring(const int *oid, char *oidbuf);
2035 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2037 Reverted modifications for ES Update definition for z_IU0Update
2038 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2039 is back to YAZ 2.0.2.
2041 String value attributes for CCL parser.
2043 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2044 which their FirstSearch server returns in Init responses, sometimes
2045 carrying useful diagnostic information when Init fails. This has the
2046 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2047 "z39.50/oclcui.asn", where its definition is somewhat different from
2048 what OCLC document on their web-site, as required to interoperate with
2051 Support for anonymous authentication in yaz-client. Use the command
2054 * Fix the OID of the Index Data-local "admin" Extended Service from
2055 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2056 the 1000, which indicates a locally-defined OID, was a mistake.
2058 --- 2.0.3 2003/06/20
2060 Fix CCL directive @case handling so that it affects string match for
2061 both CCL keywords and qualifiers.
2063 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2064 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2065 Decoder has been updated with ASN.1 changes as listed in
2066 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2067 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2068 z_IUUpdate, remains unchanged.
2070 ZOOM_record_get may now return a record in a specific character set.
2071 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2072 "from" is the character set of record as returned by target. "to" is
2073 the character set to be returned. If omitted, "to" is UTF-8.
2075 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2077 New ODR utility, odr_getelement, which returns name of element for
2078 which encoding/decoding failed.
2080 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2081 in cases where a required element was omitted.
2083 Bug fix: some MARC8 sequences were not converted.
2085 New ZOOM option "step" which specifies number of records to be
2086 retrieved in one chunk. Used in conjunction with "start" and "count".
2088 SRW support for yaz-client. Use scheme http: to use it, e.g.
2091 yaz-client no longer does (un)intelligent character set conversions
2092 by default. Can be enabled with charset and marc_charset commands.
2094 xmalloc trace fix for 64-bit systems such as DEC alpha.
2096 Solaris 2.6 compile fix.
2098 New function, cql_strerror() translates SRW error codes, as returned
2099 by cql_transform_error(), into human-readable English strings. Used
2100 in yaz-client diagnostics when appropriate.
2102 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2103 converts it into a type-1 query which is sent to the server. This
2104 makes CQL available for use with all Z-servers, as opposed to the tiny
2105 minority that can handle CQL queries themselves.
2107 --- 2.0.2 2003/04/28
2109 New Debian package layout similar to the Redhat Package layout.
2111 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2112 and search result respectively.
2114 --- 2.0.1 2003/04/25
2116 Redhat package is now several packages: libyaz (runtime libraries),
2117 libyaz-devel (development and documentation, and yaz (utility programs).
2118 Package spec file by Morten Bogeskov.
2120 New member 'schema' in struct bend_fetch_rr which the name of requested
2121 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2122 handler MAY set this to reflect the schema of the returned record.
2124 New member 'display_term' in struct scan_entry. GFS now sets member entries
2125 and allocates scan entries to be filled by user scan handler. In previous
2126 version, entries member was allocated by the scan handler. That still works,
2127 but the GFS will ignore member display_term - assuming it was NOT set by
2128 the handler. The fact that the GFS now allocates the entries both allows
2129 for new members and makes a scan handler easier to write.
2131 Fix CQL lex buffer overflow.
2133 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2134 SRU default recordPacking is string.
2136 SRU protocol support for frontend server.
2138 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2140 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2142 Added scan for the ZOOM shell (zoomsh).
2146 * String Identifers for Schemas (Amendment 5).
2147 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2148 Old definition for schema
2149 Odr_oid *schema; /* OPT */
2154 Z_InternationalString *uri;
2155 #define Z_Schema_oid 1
2156 #define Z_Schema_uri 2
2159 * resultCount parameter to Sort Response (Amendment 1).
2160 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2162 Support for SRW 1.0 over HTTP. This is an optional feature and
2163 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2166 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2167 on the same port. SRW SearchRetrieveRequests are mapped
2168 to bend_init,bend_search,bend_fetch,bend_close.
2170 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2172 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2173 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2175 ZOOM connections are SRW based if schem http is used for hostname
2176 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2177 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2179 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2180 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2181 distance=n, order=true/false, relation=le, prox unit=word. If
2182 n is omitted, distance 1 is used.
2184 Fixed problem with C compiler include path in wrong order.
2186 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2187 on Solaris. Patch from Ko van der Sloot.
2189 New MARC decode API. All new functions operate on a yaz_marc_t
2190 handle. The most important new functions are: yaz_marc_create,
2191 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2192 decode and destroy respectively. Decoder can produce formats
2193 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2194 include/yaz/marcdisp.h.
2196 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2197 to UTF-8, UCS-32, wchar_t or Latin-1.
2199 * Prototypes for yaz_iconv_-functions moved to separate header
2200 include/yaz/yaz-iconv.h.
2202 Make a few private functions 'static' in unix.c. This prevents
2203 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2205 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2206 are set when Init Response is received.
2208 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2209 but returns diagnostic set as well.
2211 New function yaz_strerror which is a portable wrapper for
2212 strerror/strerror_r/GetLastMessage.
2214 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2215 is returned for MARC. If type is "oai", then OAI MARC is returned.
2217 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2220 --- 1.9.2 2002/11/26
2222 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2224 Fix bad race conditions on SIGTERM and terminate gracefully in
2227 Move retrieval (data1) module to Zebra since nobody seems to be
2230 Add GRS-1 render for ZOOM using same format as yaz-client.
2232 --- 1.9.1 2002/10/05
2234 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2236 Fix broken ESpec handling in data1 module.
2238 SGML reader parses comments and makes them part of the data1 tree.
2240 Added several type casts so that YAZ compiles as C++ code.
2242 ZOOM didn't handle PDU encoding failures properly.
2244 Added more Bib-1 diagnostics (approved extensions).
2246 GNU configure: better check for iconv.
2248 More portable use of accept, getpeername. Check for socklen_t. Use
2249 int/size_t if socklen_t is not defined.
2253 PQF parser rejects bad queries - including those with extra
2254 characters in them. PQF parser used to silently ignore that.
2255 Cleaner API for PQF added, which allows you to get detailed
2256 error information for bad queries (see yaz/pquery.h).
2258 Fixed bug in ZOOM_record_get for type "database".
2260 Implemented mini iconv library supporting conversions between
2261 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2263 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2265 --- 1.8.9 2002/08/20
2267 Fixed ZOOM C record cache so that preferredRecordSyntax and
2268 elementSetName is used to check for already fetched records.
2270 --- 1.8.8 2002/08/02
2272 Added three members in bend_initrequest structure to facilitate
2273 character set negotiation.
2275 Fixed a bug in frontend server that could cause indefinite
2276 loops under rare conditions.
2278 Revised character set utilities (charneg.h) so that encoding
2279 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2281 For PQF, directive @term <type> sets term type for Scan/Search.
2282 Here <type> is general, string, numeric, null. The term type
2283 is inherited - just like @attr.
2285 New call odr_set_charset that sets character set conversion for
2286 international-strings on a ODR stream. Prototype is:
2287 int odr_set_charset(ODR o, const char *to, const char *from);
2288 The InternationalString is still represented as C string in YAZ
2289 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2290 won't). On the protocol level, you can use any encoding.
2292 Support for UNIX sockets in ZOOM.
2294 Solaris recv sometimes returns errno == ENOENT. It is treated as
2295 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2297 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2298 both client and server. Code by Morten Bogeskov.
2300 --- 1.8.7 2002/05/22
2302 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2303 that they can be used directly from Visual Basic. You must recompile
2304 your windows APP if you're using ZOOM.
2306 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2307 Commands "lang" and "charset" sets language and character set respectively.
2308 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2309 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2311 Attributes from multiple CCL fields may be OR'ed rather than merged
2312 using directive "@field or". Fields are still merged by default -
2313 equivalent to "@field merge".
2315 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2318 Fixed bug in zget for parameter ExtendedServicesResponse.
2322 --- 1.8.6 2002/03/25
2324 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2326 Client displays USR.1:SearchResult-1 (hits per term).
2328 Additional Search Info for search in Generic Frontend Server.
2330 Fixed CCL parsing of "field=s".
2332 WIN32 installer - using the excellent NSIS software from nullsoft.
2334 Fixed CCL parsing of "field = - <number>".
2336 Added function yaz_marc_decode that decodes MARC for line mode
2337 display or XML (similar to that used by JZKit).
2339 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2340 Z39.50. But ISO/ILL was, however.
2342 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2343 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2345 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2346 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2348 --- 1.8.5 2002/02/03
2350 New YAZ client features: Command completion and new commands:
2351 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2352 Code provided by Jacob Poulsen.
2354 New call oid_trav, that visits all registered OIDs via callback.
2356 Function ZOOM_record_get now returns const char pointer rather than
2357 void pointer. It saves a lot of type casts.
2359 For YAZ client, command "auth" now allows you to set authentication
2360 in IdPass style. It is enabled when three tokens are given - order
2361 is user, group and password.
2363 Fix memory leaks in MARC record handling for ZOOM.
2365 New option for YAZ client, -k <kilobytes> that sets
2366 maximum record size. Similar to -k option for generic frontend
2367 server and yaz-ztest.
2369 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2371 Prefix query parser reports "fail" when bad attribute set is given.
2373 Fix in MARC decoder. Proximity logging. Fix for attribute set
2374 in scan handler for server. Patches by Shigeru Ishida.
2376 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2379 Configure option --with-openssl=<dir> now works when a directory is
2380 specified. Patch provided by Morten Bogeskov.
2382 New option for YAZ client, -u <auth>, that sets authentication.
2384 ZOOM fix: error information was sometimes "missing", since error
2385 was cleared/reset too when it shouldn't.
2387 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2389 --- 1.8.4 2002/01/04
2391 Scan for ZOOM API. New object ZOOM_scanset. New functions
2392 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2393 ZOOM_scanset_destroy.
2395 New ZOOM function, ZOOM_connection_last_event, that returns type
2396 of last event (such as "receive data", "send data", "apdu received",
2399 New ZOOM option, schema, that specifies schema for retrieval.
2401 New CCL feature. Qualifiers can be aliases for one or more
2402 other qualifiers (if more than one is given, OR is used).
2404 ZOOM uses named result sets if target supports it.
2406 Two new YAZ client commands: . (dot, which sources a script of YAZ
2407 client commands), and ! (to execute shell command.). Implemented
2410 Working on Debian packages.
2412 --- 1.8.3 2001/11/19
2414 YAZ client enables named result sets only if target supports it.
2416 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2418 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2419 with key="host" to get same result.
2421 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2422 Function Z3950_resultset_record(s) returns references to records
2423 "owned" by resultset. To become owner use Z3950_record_clone.
2425 Function z_ext_record handles Extended Services. Thanks to
2428 --- 1.8.2 2001/11/12
2430 CCL Parser fix: ignore token comma when dealing with and-lists.
2432 Documentation updates for COMSTACK.
2434 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2435 Changed prototype Z3950_records. For some functions, int parameters
2436 were changed to size_t.
2438 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2441 New MARC decode/display function, marc_display_exl, which properly rejects
2442 non-ISO2709 records. YAZ client uses it.
2444 --- 1.8.1 2001/10/29
2446 Fix bug: local attribute set wasn't set correctly in PQF strings.
2450 * Old Z39.50 codecs no longer supported.
2452 Added ZOOM C binding. See http://zoom.z3950.org/
2454 Renamed states for COMSTACKs to avoid confusion with events.
2456 Implemented cs_look and proper cs_rcvconnect.
2458 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2460 Configure detects POSIX threads on OpenBSD.
2462 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2463 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2465 When error is returned from present handler, non-surrogate diagnostic
2466 is returned in present response (and fetch handler is no longer called).
2468 * Minor adjustments to pquery parser (PQF). Token characters may be
2469 escaped by using backslash (C-style).
2471 PQF parser allows string attribute values to be specified. For @attr,
2472 non-numeric characters after the equal-sign are treated as strings
2473 (e.g. @attr 9=title).
2475 CCL trunction character may be defined (@truncation in file)
2477 * function zget_ExtendedServicesRequest sets waitAction to
2478 waitIfPossible (was wait).
2480 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2483 CCL operator names may be set in field definition files (CCL_bibset).
2484 See ccl/bib1 for an example.
2486 Fixes in ASN.1 compiler for C++ compatibility.
2488 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2489 and "op_or" to avoid conflict with C++.
2491 Fixed problem with GNU readline detection on Redhat 7.0.
2493 Added step-size for Scan backend handler.
2495 Fixed bug that made the frontend server crash when no attribute
2496 set was specified for scan.
2498 Front-end server automatically switches to original working directory
2499 when installed as an NT service. Previously -w had to be specified to
2502 Added extended attributes for retrieval module (data1), so that data1
2503 records carry d1_readXML/SGML attributes. d1_read also supports
2504 null-data rules ( <tag/>)
2506 On UNIX when POSIX threads are available, a separate library libyazthread
2507 is created. Programmers should link with that library and the yaz library
2508 when using threads. The reason for the split was that some applications
2509 on Linux, such as Apache, doesn't work well when using shared objects that
2512 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2513 (or any frontend server) in SSL mode by specifying ssl: followed by
2514 address. Only tested on UNIX.
2516 Added feature for CCL module. Virtual structure s=al or s=ol generates
2517 and-list and or-list respectively instead of phrase search.
2521 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2522 log_mask_str. This was done to avoid name conflicts with other libraries
2523 (such as other PHP extensions).
2525 Added raw OID member for preferred record syntax (request_format_raw)
2526 and returned record syntax (output_format_raw) for backend fetch method.
2528 Config file yaz-config now accepts options so that it returns specific
2529 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2531 Shared library support for UNIX using GNU libtool.
2533 * Modified backend interface. Request/Response struct's replaced by
2534 one read/write C struct. For example bend_fetchrequest and
2535 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2536 Every handler - even search has to be registered in bend_init
2537 handler. This means that the YAZ library no longer refers to
2538 external functions and it makes it possible to make the whole
2539 thing a single DLL/SO.
2541 Added Segment handler for backend server.
2543 Added Zmbol/Zebra administrative functions to YAZ client.
2545 Threaded frontend server on UNIX (when POSIX Threads are available).
2546 Starting the server with option -T enables multi-threading.
2550 Added configure option --enable-comp/disable-comp to control use
2551 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2552 located in sub directory asn.
2554 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2555 in ${exec_prefix}/bin along with the other programs yaz-client and
2558 GNU automake used to maintain makefiles.
2560 Added several OID's.
2562 Changed retrieval module so that we can load records with no abstract
2563 syntax defined. Tagpaths in these records are fully composed of string
2566 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2570 On UNIX, the generated makefile now supports a proper 'make install'.
2571 The prefix can be set via GNU configure to set the install location
2572 (default is /usr/local).
2574 * YAZ programs client and ztest were renamed to yaz-client and
2575 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2576 locations, such as /usr/bin,/usr/local/bin,etc.
2578 * YAZ Header files were moved from include to include/yaz. YAZ Header
2579 files are referred to as include <yaz/log.h> rather than <log.h>.
2580 The YAZ include path (-I ..) is therefore the same as before. Programmers
2581 should update their #include statements or use -Ipath/include/yaz
2582 instead. The main motivation for doing this change is that YAZ header files
2583 can be installed in "standard" locations /usr/include,/usr/local/include
2584 without introducing conflicts, since ALL YAZ header files are stored
2585 in subdirectory yaz (under /usr/include for example).
2587 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2588 rather than project/workspace files. We switched because project files
2589 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2592 Changed name of logging function, logf, to yaz_log, to prevent name
2593 clash with some math-log functions. The YAZ header log.h defines logf
2594 to yaz_log (#define) so there should be no incompatibilities by this
2597 Added bend_start/bend_stop handlers for server. These handler are
2598 called on start/stop of server. For windows they are called whenever
2599 a service is started/stopped.
2601 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2602 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2603 in util/yc.tcl. The auto-generated C code structures are, in a few
2604 cases, incompatible with the old decoders. There are differences in the
2605 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2606 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2607 The preprocessor variable ASN_COMPILED is defined when the compiled
2608 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2609 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2610 wish to use the old encoders/decoders you can specify --disable-yc
2613 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2614 version so that it supports both new - and old version of DB Update
2616 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2617 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2618 change. The name parameter can be set to 0 in which no name is specified
2619 for the construction. The macros odr_implicit and odr_explicit sets name
2620 parameter to zero for the construction involved. New macros
2621 odr_implicit_tag and odr_explicit_tag are similar to the others,
2622 except that a name parameter is added. For programmers' that don't use
2623 ODR they probably only need to change the call to z_APDU and z_External.
2625 Added access control facility by interfacing the TCP wrapper library.
2626 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2627 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2628 name of the daemon and enables the access control as specified in
2629 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2631 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2632 den Dool <H.M.vdnDool@kub.nl>.
2634 Added reference ID parameter to most functions in server API - refer
2635 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2637 Changed name of ccl library to libccl.a (was ccl.a).
2639 Fixed bug in decoder for Explain (Category TargetInfo).
2641 Added support for GNU readline in client. Thanks to Jacob Poulsen
2642 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2644 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2645 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2646 IMPLEMENTATION! This change was made to the development version before
2647 the ZIG decided to retract the amendment. If any users MUST be
2648 compatible with the original Update definition, PLEASE CONTACT US, and
2649 we will include a separate definition corresponding to the old Update
2650 ES. Note that because of the change to the ASN.1 of the
2651 TaskPackageRecordStructure we cannot define a single structure that
2652 will support both versions.
2654 * Added const modifier to buffer parameter for some ODR/BER encoding
2655 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2656 completeWAIS, odr_dumpBER.
2658 Fixed bug in client.c which caused a crash when a scanResponse didn't
2659 contain positionOfTerm.
2661 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2662 * will cause an error in a client if a non-YAZ target sends both a
2663 * list of Scan entries and non-surrogate diagnostics.
2665 Retrieval module enhancements. Tag sets may be typed in the reference
2666 to it. From the .abs-file the "tagset" directive takes a third optional
2667 integer type for the tag set referenced. From a .tag-file the "include"
2668 directive takes a third optional type as well. The old "type" directive
2669 in the tag set itself is still recognized but acts as the default type
2672 Backend interface change. Individual Scan terms returned from bend_scan
2673 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2674 in include/backend.h.
2676 Retrieval module enhancements. Multiple tag sets and attribute sets may
2677 be specified in abstract syntax specs. Revised the error/warning for
2678 logging messages reported by the retrieval module when reading the
2681 Object Identifier system (oid_..) changed. The API is backwards
2682 compatible but the oid-routines now allocates new OID's when needed.
2683 Raw OID's may be specified in oid_getvalbyname.
2685 YAZ now uses GNU configure to generate Makefile(s).
2687 * Minor changes in some of the member names of DeleteResultSetRequest and
2688 DeleteResultSetResponse. See include/proto.h.
2690 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2691 and added member 'languages' in TargetInfo (which was missing).
2693 Changed the way attribute sets are handled in the retrieval
2694 module. These are now cached, just like the abstract syntaxes
2697 Changed YAZ so that it links with compiled ASN.1.
2699 Added Explain-schema definitions and mapping routines. The following
2700 Explain categories have been implemented: AttributeDetails,
2701 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2703 Fixed minor bug in Windows version of Server Library.
2705 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2707 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2709 Added EXTERNAL: UNIverse Resource Report (non-standard).
2711 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2712 ENUMERATED and SET OF.
2714 * Added 'const' to some of the char pointer arguments for the
2715 functions, data1_read_node, data1_getelementbytagname,
2716 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2719 Fixed bug in data1_insert_taggeddata - the last_child member of
2720 parent wasn't initialised.
2722 * Changed data1_read_record and data1_read_node so that the supplied
2723 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2724 doesn't refer to any parts of the "SGML"-buffer.
2726 Fixed bug in server library (Windows version of statserv_remove).
2728 * Changed code so that it compiles as C++. The type definition
2729 of Odr_fun which is a member of Odr_arm was changed. The result is,
2730 that an explicit typecast is needed for the fun pointer when
2731 using Odr_arm - as in:
2732 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2734 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2736 Implemented the new structured date and time definition as approved
2737 by the ZIG. Added schemaId element to the specificTag in Espec-1
2738 (also approved at the last ZIG). Thanks to RVDM.
2740 Added some Object identifiers (RVDM).
2742 Changed the Update Extended Service (RVDM).
2744 Added command "refid" to client which specifies referenceId for
2745 the following requests.
2747 Implemented extended service handling for server. See ztest.c
2748 for an example as well as backend.h. New handlers are registerd
2749 in the Init handler.
2751 * Changed interface for sort in server.
2753 Added new members to statserv_options_block. It allows a server
2754 to read options from another source than just the command line. Thanks
2755 to Charles Woodfield.
2757 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2758 renamed to zboolean. Some C++ compilers complained about the name.
2760 Minor changes to gils.abs. Added index 's' (sort) on title
2761 and date/time-last-modified.
2763 --- 1.4pl2 1998/1/30
2765 Fixed bug in server library regarding inetd mode (-i). This bug
2766 was introduced by release 1.4.
2768 --- 1.4pl1 1998/1/29
2770 Added sort facility in client and backend server interface.
2772 Fixed problem with dependencies in Makefile(s).
2774 Fixed bugs for encoders/decoders of extended services and
2777 Implemented sub-tree feature for schemas. Sub-trees are
2778 referenced in *.abs-files. See explain.abs for an example
2779 of the use of this feature.
2781 Modified bib1.att; local attributes for ANY didn't include
2782 ANY itself (only affects use of the retrieval module).
2784 Fixed bug in plain SGML reader in function data1_read_node:
2785 tags with prefix "var" was incorrectly interpreted as variants.
2787 Added feature "sub-schemas" to enable references to - and definitions
2788 of - group of elements.
2790 * Removed member parent from type data1_element (in data1.h).
2792 Implemented function odr_nullval() that returns the value of
2795 * Removed member num_children from data1_node (in data1.h).
2797 Made NT service interface part of the server library. The
2798 function statserv_main uses the NT service when required and
2799 calls the statserv_start / statserv_close routines.
2801 Routine zget_SearchRequest and zget_PresentRequest fills
2802 resultSetName/Id member with "default" instead of "Default".
2804 Fixed memory leak in server. Request queue member wasn't freed.
2806 Fixed nmem_exit so that memory is freed.
2810 Revised the CCL parser utility to be thread safe.
2812 Added function, oid_ent_to_oid, to replace the function
2813 oid_getoidbyent, which is not thread safe.
2815 * Added nmem_init and nmem_exit to initialize and release
2816 NMEM resources. Function nmem_init should be called once in the
2817 initial thread before NMEM/ODR is used. statserv.c and client.c
2818 have been changed accordingly. The change was necessary to make
2819 NMEM thread safe. The NMEM memory pool is shared amongst threads
2820 in a process. Unix-based applications will still work fine without
2823 Added NT Services interface for the the Z39.50 (statserv) Server.
2824 Refer to the ztest.c source on the usage.
2826 Windows 95/NT port using MSVC5.0. Project files are included in the
2829 * Defined new 'global' handle for the retrieval (data1) system. The
2830 new handled, data1_handle, describes the state of the data1 system.
2831 This handle is passed as first argument to virtually all
2832 data1 related routines. The functions data1_create and data1_destroy
2833 creates and destroys a data1 handle respectively.
2835 Added ODR encode stream member to all backend request structures
2836 init, search, scan etc. This stream should be used to allocate all
2837 memory used for the response when thread safe operation is needed.
2839 Changed the comstack utility, cs_addstr, to be thread safe. The
2840 returned hostname string returned by the function is now part the
2843 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2844 function. The cs_straddr takes a COMSTACK handle as argument, so this
2845 function must be used after cs_create and before bind/connect.
2846 This function is thread safe.
2848 Moved test server to 'ztest' directory - generic server code still
2849 in 'server' directory.
2851 Made prefix query (pquery.c) utility thread safe.
2853 Added new function modifier YAZ_EXPORT to 'export' public DLL
2854 functions when using windows (see include/yconfig.h).
2856 Added definitions to the OID database (util/oid.c) (RVDM).
2858 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2860 Added call to ccl_rpn_delete in client program.
2862 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2863 release of RPN structure.
2865 Added support for C++, headers uses extern "C" for public definitions.
2866 With input from RVDM.
2868 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2869 Thanks to Ronald van der Meer (RVDM).
2871 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2873 Added support for private extensions to the OID database
2874 (oid_setprivateoids()). Thanks to RVDM.
2876 Added optional, physical ANY (key replication)
2878 Fixed null-reference problem in GRS-1 output filter.
2880 Proximity operator added to Prefix Query Format (PQF).
2882 In test client command "base" accepts multiple databases.
2884 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2888 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2890 Smallish bug-fixes in the new encoders/decoders (explain).
2892 Bug fixed in DeleteRequest.
2894 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2896 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2898 Added SOIF syntax (using private OID for now) to retrieval module and client.
2900 Added Update extended service.
2902 Added SearchResult-1 additional info structure.
2904 Added optional CCL (ISO8777) interpreter as separate module. Available
2907 --- 1.2 1996/6/10 (1st anniversary release)
2909 Added Summary record syntax. Lightly tested.
2911 Added OPAC record syntax. Untested.
2913 Added ResourceReport service encoders/decoders. Untested.
2915 Fixed bug in z_Unit - wrong tagging on unitSystem.
2917 Fixed bug in the DiagRecs decoder.
2919 Added options for max PDU size and session timeout to frontend-server.
2921 Added documentation of query-language parsers and other supporting utilities.
2923 [frontend-server] Added Attribute set to the bend_scanrequest API.
2925 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2926 surrogate diagnostics were generated.
2928 [retrieval] Allow multiple local values for attribute.
2930 [retrieval] Allow multiple attributes per element in .abs files. index type.
2932 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2934 --- 1.1pl2 1996/4/10
2936 Minor changes, mostly specific to Zebra's requirements (retrieval)
2940 Repaired bug in frontend server when running multiple listening
2941 endpoints in dynamic mode.
2943 z_External() now won't break if a known, ASN.1 value comes encapsulated
2944 in an octet-string. The value will pass through unmodified in an Odr_oct.
2946 Added a bit of code to the demo client to decode & display
2947 ASN.1-structured records represented in the octet-aligned branch of
2948 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2950 Added z_ext_getentbyref() to the ASN module. Doc updated.
2952 * Completed the SCAN definition in the ASN module. This may break SCAN
2953 code based on older YAZ-versions at compile-time. The fix is easy -
2956 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2957 under the SCAN definition. Remember to initialize this, server-people.
2959 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2960 that this does not extend to ODR and ASN.
2962 Comstack allows insertion of established socket (primarily for
2963 inetd-operation of servers). Doc updated.
2965 Front-end server can now start from the inetd in TCP mode. Doc
2968 --- 1.0pl4 1996/1/24
2972 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2973 the rank and record number.
2975 Adjustments to the frontend server.
2977 Fixed diagnostic BER dumper. It ignored the file argument.
2981 Various changes to retrieval module.
2983 Changed the union discriminators of the protocol files from enums to
2984 ints paired with #defines.
2986 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2989 *Changed operator in the RPN structure to 'roperator', again to avoid a
2992 Fixed problems in Explain decoders/encoders.
2994 --- 1.0pl2 1995/12/6
2996 Memory bug in log module fixed.
2998 --- 1.0pl1 1995/12/5
3000 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3002 Bug in Explain DatabaseInfo module fixed.
3004 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3008 The shift to v1.0 signals that we now consider the *core* functionality
3009 of YAZ reasonably stable (the core being more or less equivalent to
3010 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3011 tested (Explain not at all - though that will happen soonish).
3013 Minor changes to code to support Windows port.
3015 Various minor changes after we're getting to use GRS-1 & co. more.
3017 Added Espec-1 format.
3019 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3020 of the protocol and it cannot be selected when encoding (maps into 'string'
3021 when decoding). Needed to talk to some servers.
3023 Demo client can request simple element set names.
3025 Added Diagnostic Format encoders/decoders.
3027 Added simple Close handling to frontend server (no hooks for resource
3028 reporting yet), and demonstration client.
3030 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3032 --- 1.0b3 1995/08/24
3034 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3035 handled incorrectly when records were requested in the searchResponse. This
3036 will only affect you if you use the frontend-server.
3038 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3039 Test-client will ask for and print GRS1. Ztest will return dummy records
3042 Added Explain encoders/decoders to the service-level API. Untested.
3044 Added Extended Services: Item Order encoders and decoders to the Service-
3045 level API. Untested. We could use a recent copy of the pertinent bits
3046 of the ILL protocol to add those bits.
3048 Added diagnostic format 1 encoders/decoders to the service-level API.
3051 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3052 odr_cons.c, which causes a more correct output.
3054 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3055 was always set to 0 when no records were requested in the searchRequest.
3057 * Added better external-handling. This shouldn't harm old code that
3058 *encodes* externals. It can break code that looks for a
3059 'single-ASN1-type' representation, since those types that are known
3060 are now decoded immediately. Look at the SUTRS sample code in
3061 seshigh.c and client.c. Documentation updated.
3063 Handling of structured records in bend_fetchresponse. Length -1 marks
3064 structured record, type is deduced from format field.
3066 --- 1.0b2 1995/06/27
3067 Fairly quick maintenance release to add SUTRS support.
3069 Fixed handling of SUTRS records in the demonstration client.
3071 * Added format field to the bend_fetchrequest and bend_fetchresponce
3072 structures of the backend API (frontend server). When the record is
3073 returned, the value of the format field is mapped to an OID. The
3074 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3075 of the record. The special value VAL_NONE in the bend_request means
3076 that no specific format was requested by the client. Documentation
3077 updated accordingly. Test server (ztest) will return a fixed dummy
3078 SUTRS record if your client requests SUTRS.
3080 Documentation updated accordingly.
3082 You can now set external libraries and RANLIB support in the top-level
3086 First public release.
