3 record_conv: modify new API for conversion types. The conversion types
4 may be passed in new functions yaz_record_conv_configure_t and
5 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
7 Avoid mixed statement/variable declare; fixes compilation with Visual
12 Add non-standard SRU diagnostic: 235: "Database does not exist".
13 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
14 Update SRU to Bib-1 diagnostic maps accordingly.
16 CCL: add two new diagnostics for unsupported masking. The new
17 diagnostics are: "Embedded truncation not supported" and
18 "Single charcacter mask not supported".
22 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
26 Build YAZ for Ubuntu Oneiric.
28 CCL: allow parantheses for proximity operands. For example CCL query
29 (a) % (b) is now allowed.
31 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
32 marked dead, rather then being destroyed. If not, the session memory is
33 being free'd before the search/scan handler is finished. Also destroy
34 'request' memory in request_release rather than in various places,
35 which resulted in leaks from time to time.
39 cql_sortby_to_sortkeys: honor sort prefix.
41 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
42 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
43 The rpn2cql family of functions now always returns quoted CQL terms.
45 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
49 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
50 sequence is treated as one. For example, &&a=b&&&c& is identical to
55 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
56 APDUs for a connection to a WRBUF.
60 Fix cql_sortby_to_sortkeys. Completely broken before.
62 Make CCL's @truncation work again.
66 New ZOOM connection setting: tproxy. It's like proxy, but does not
67 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
68 to set resolved address + port for a connection outside ZOOM itself.
70 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
74 Fix uninitialized variable in Solr spell support (could cause SEGV
75 for SRU response decoding).
77 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
78 back-end's addinfo through into the ZOOM response addinfo.
80 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
81 they are separated by a colon and a space rather than simply
86 Add support for Solr spell-checking/suggestions through ZOOM.
87 If a Solr target has been configured correctly for spelling-checking
88 and suggestions, these will now be returned on the ResultSet option
89 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
93 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
94 with a flag whether to substitute escape sequences or not.
98 Fix nmem_strsplit_escape to substitute escape char properly.
100 New option for zoomsh -e , which makes it abort on first error and
101 return process exit code to indicate success/failure.
103 YAZ options utility supports special option -- which makes all it treat
104 all following arguments as non-options.
106 --- 4.2.15 2011/09/16
108 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
109 searched if absolute filename is given.
111 Fix conv_xslt() error-reporting when stylesheet is not found.
112 (The value of fullpath is meaningless in this situation.)
114 --- 4.2.14 2011/09/07
116 Fix problem in CQL sort node creation: un-initialized memory.
118 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
119 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
120 CQL sortby depending on whether Type-1 or CQL is actually sent to the
123 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
124 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
126 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
127 will make it possible to use both single-character mask (#) and wildcard (?)
128 in CCL . Throw diagnostic for left truncation because that is not supported
131 --- 4.2.13 2011/09/01
133 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
134 cases using escapes (\-sequences) and masking.
136 PQF parse fix: A trailing backslash followed by end-of-string (\0)
137 would result in a read one byte beyond string.
139 rpn2ccl may use Z39.50 masking for terms (t=z).
141 ICU check fix. Don't include library -lCrun on Solaris, unless present.
143 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
144 not --cppflags (which seeems like an error in icu-config).
146 --- 4.2.12 2011/08/27 RPM package only
148 cql2ccl: fix conversion of terms: operator characters were not
151 --- 4.2.11 2011/08/25 RPM package only
153 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
154 CCL parser will map both # and ? to their regular expression
155 quivalents (. and .*).
157 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
158 of reserved CQL characters.
160 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
161 is, so that they are passed through.
163 --- 4.2.10 2011/08/24
165 ZOOM SRU mode: more aggressive re-connect.
167 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
168 made available as a utility function, declared in <yaz/logrpn.h>
170 rpn2cql_structure() supports proximity nodes (except that the Type-1
171 proximity node's "exclusion" binary is ignored, as there is no way to
172 express that in CQL). Fixes bug #4564.
176 Fix SEGV that could occur if set command of zoomsh was given without
177 value (2nd argument).
179 Fix SEGV that could occur if unsupported transport was given for
180 COMSTACK - say https (when SSL was unavailable).
182 Build yaz-url on Windows too.
186 New utility to get web content. Header is url.h. A command line tool
187 yaz-url is part of the distribution and packages.
189 Fixes for SSL COMSTACK (when gnutls is in use).
191 New functions yaz_base64{encode,decode}. Header is base64.h.
195 ZOOM C includes HTTP response buffer as additional info if it fails
196 to decode the SRU response.
198 Make wrbuf_json_puts available.
202 zoom: throw diagnostic for invalid value for option "sru". Before a
203 bad SRU request was sent.
205 Adding new utility wrbuf_vp_puts.
207 Add cclxmlconfig.obj to win/makefile. It was missing completely.
211 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
212 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
213 redirect was used at the same time.
215 MARC line mode decoding: be less picky about length given - first
216 5 digits of header that is.
218 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
220 Changes to decoding of SRU records: a record with recordPacking=xml is
221 modified with a new root element <yaz_record> if the recordData contains
222 multiple children elements. This is to make the record XML parseable
225 RPN to SOLR conversion: encode special characters.
227 Generic Frontend Server: fix uinitialized member, stepSize.
231 Fix a bug in SRU decoding of records.. The database records stored
232 had un-initialized memory, but it would only be seen with yaz_record_render
233 and type_spec="ext" .
235 Fix a bug in ccl_qual_dup introduced in 4.2.3.
239 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
243 Add new utilities to convert from CQL to CCL . These utilities have
244 prefix cql_to_ccl defined in cql.h.
246 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
247 lead to memory heap corruptions when ICU utilities were in use.
251 Make compilation work without Libxml2.
253 yaz-client: remove redundant blanks in display of searchResult-1 term
258 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
259 resulting CQL node (tree) in a new node CQL_NODE_SORT.
261 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
262 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
263 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
264 Note that the CQL sortby spec is only converted when the GFS is already
265 converting from CQL to RPN (cql2rpn element).
267 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
268 specify whether to collapse delimitors or not. The existing nmem_strsplit
269 do collapse (collapse parameter = 1).
271 Windows installer: For NSIS, set InstallDir depending on x86/x64.
273 Rename internal func yaz_use_attribute_create. While non-static, this
274 function is not declared in a public header.
278 Add -lCrun when linking with ICU on Solaris.
280 More quicks character set conversions for OPAC records.
284 fix problem with record_render: records were converted (character set
285 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
289 SRU: add methods for handling DADS SRU-proxy facets.
291 Separate OPAC record character set for ZOOM_record. yaz_record_render
292 allows a character set given as charset=from/opacfrom,to where 'from' is
293 the character set of a bibliographic record, 'opacfrom' is character set
294 of OPAC record and 'to' is the target character set.
298 yaz-client: show may XML format records. Command show followed by 'format'
299 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
302 src/stemmer.c: Avoid using unnamed union. It is not supported by some
305 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
308 Update yaz.spec to operate on both SLES11 / Centos 5.5.
310 RPM: Release includes 'indexdata' name. Use indexdata in release name so
311 this package can be distinguished from other vendors.
313 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
314 as determined by configure
316 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
318 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
319 returns no error and no record, the present request is considered
320 partial (only a subset of the records could be returned by backend), and
321 so it is appropriate to set Present Status to partial-4.
325 Move yaz-config man pages to section 1.
327 More documentation about SOLR.
329 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
330 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
331 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
332 peers on some Linux systems. However, in general that does not work
333 so YAZ can not rely on that to work. Debian changed behavior in this
334 respect from Debian lenny to Debian squeeze (still testing as of Oct
336 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
338 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
342 Fix yaz-config output: echo_source not set correctly by configure.
346 SOLR WebService support for yaz-client and ZOOM.
348 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
350 --- 4.0.12 2010/08/17
352 Z39.50 facet support. Facet specifications are passed for search in
353 other-information with ASN.1 as defined in facet.asn and OID
354 .10.1000.81.5 . Facets are expressed as an Attribute list as known
355 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
356 3 is limit (number of entries to get in response). yaz-ztest returns
357 dummy facets if a client asks for them.
359 --- 4.0.11 2010/07/09
361 CCL fixes: bug 2895 and bug 3539.
363 GR1-display: add comma in display - was removed by mistake in
366 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
368 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
370 --- 4.0.10 2010/06/18
372 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
373 result set from a connection. The result set will be on its own
374 thereafter; no operations on it will perform retrievals from a target.
375 Only cached copies are returned.
377 ZOOM C:fix case for HTTP servers responding with Connection:close.
378 Ensure that if there is a current task it is resumed (like fetching
379 more records in a result set) . Bug #3484.
381 PQF parser: use odr_atoi for Odr_int (not atoi)
383 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
384 values that contain any non-digits are treated as string attributes
385 (previously decoding only checked for leading character ([0-9]). PQF
386 encoding: attribute string values are not surrounded by double-quotes.
390 New utility for managing threads - thread_create.h.
392 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
393 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
394 but YAZ' implementation do.
396 Fixes for yaz_cond-functions on Windows 7.
398 DLL export more symbols.
400 zoomsh: show record do NOT render opac.
402 Remove *.la files from Debian and RPM packages.
406 Debian package libyaz-dev depends on libgnutls-dev again (was
407 removed in YAZ 4.0.6, but due to Libtool it is still needed
408 even though yaz-config do not list libgnutls libs).
410 ZOOM: Use only one WRBUF for returning string results for
411 ZOOM_resultset. Reduces memory usage for ZOOM in general.
413 ZOOM: ZOOM_connection do not use a shared pointer to
414 ZOOM_resultset after ZOOM_resultset is destructed by
415 user. Reverts to YAZ 4.0.4 behavior.
419 record-conv: fix problem with at least one XSL conversion -
420 due to probably incorrect usage of XML XSL documents.
424 Fix yaz-config for static mode and the use of SSL (gnutls).
428 Forward decl timeval struct in mutex.h and gettimeofday.h.
430 yaz-config: fix 'static' mode linking.
434 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
435 are wrappers for pthreads or Windows. For Windows these are put in
436 a separate DLL: yaz_cond4.
438 libyaz.la (whole source) is compiled with thread. If thread support
439 is enabled enabled, all source of YAZ is compiled with treading support.
440 This allows core utilities such as yaz_log to use thread facilities.
441 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
442 thread utilities. This commit moves mutex utilities (mutex.c) from
443 libyaz_server.la to libyaz.la.
445 yaz-json-parse displays leading text until error.
449 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
450 patch from Giannis Kosmas.
452 SRU: no longer URL encode SRU database. The URL for an SRU server is
453 a URL and such is alreeady encoded - at least when given with leading
454 http:// or https://. This reverts behavior to YAZ 3.0.50.
456 Support for new MARC XML notation TurboMARC which like MARCXML is a
457 complete representation of MARC/ISO2709.. This one, however, is more
458 compact and allows for faster processing with XSLT. TurboMARC can be
459 used in the marcdisp.h API, from the yaz-marcdump utility and from
462 yaz-ztest can be configured - via the database - to perform certain
463 delays when it performs operations search, present and single record
464 fetch. This allows testers to make yaz-ztest act as a real or even slow
465 Z39.50 server. Refer to the yaz-ztest man pages for details.
469 wrbuf_destroy allows NULL WRBUF passed to it.
471 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
473 Add ZOOM_connection_close.
475 No fixed size buffers for ZOOM shell - bug #3257.
477 tstodr: make it work on s390 platform.
479 New icu iterator-functions. The new icu_iter-functions makes it possible
480 to use ICU chains from many threads.
482 yaz-client: better syntax check for show command.
486 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
489 New simple local-file XML include facility which allows file glob-patterns.
490 Refer to yaz/xml_include.h.
492 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
495 ZOOM_record_get supports new parameter "format" which makes it format XML
498 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
499 JSONText in ECMA-262) is JSONValue, not JSONObject.
503 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
504 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
506 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
507 POSIX/Unix builds .so with major version 4.
509 Remove old LOG_-defines from log.h. They have been obsolete and
510 undefined by default for the last 5 years.
512 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
514 GFS: Remove socket (int *fd) from search_rr handler. The socket
515 descriptor ptr is a facility that allowed a search handler to supply
516 a socket which would serve as a callback - when search was complete.
517 This facility has now been in use for years.
519 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
520 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
521 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
522 returns 'const char *' rather than 'char *. The returned string is
523 read-only and should not be modified by applications. COMSTACK cs_close is
524 now a void function - it no longer returns int. No applications check for
525 the value and the implementations has always returned 0.
527 ZOOM: use size_t for scan hit counts and str size. Functions
528 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
529 occ (hit count) and len (string length) are now of type size_t pointer
530 rather than int pointer. This is to be able to represent large hit counts
531 and to also just to use the proper type for string length (strlen result).
533 New JSON parser. Refer to include/yaz/json.h .
535 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
536 Used to be int in some cases. Many wrbuf_-functions used to return an int
537 indicating some length.. These return values were never used. And so they
540 ODR: odr_malloc, odr_total now takes size_t for size.
542 clone_z_type: fix leak; occurred for encoding failures.
544 --- 3.0.52 2009/12/03
546 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
547 bug was introduced in 3.0.51.
549 --- 3.0.51 2009/12/02
551 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
553 tcpip comstack: fix leak for getaddrinfo.
555 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
556 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
557 Decoding of SRU "path" database is performed by private function
558 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
559 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
561 yaz-client: honor base command for SRU. Change when database setting
562 is applied for SRU and ensure it is kept when a connection is reset.
563 Change also the way errors are displayed or SRU (decoding of packages).
565 --- 3.0.50 2009/11/02
567 Add support for extra request / response data for SRU codecs and GFS.
568 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
569 for extra data response buffer and length. For the GFS, both request
570 and response data (XML) is carried in extra_args and extra_response_data
571 for the search handler. Patch by Ko van der Sloot.
573 ZOOM: For queries that cannot be converted to the specified rpnCharset,
574 ZOOM now returns a diagnostic on the client-side ('invalid query' /
575 10010). This fixes bug #2113.
577 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
578 cmdfile included a 'quit' command that would result in a memory violation.
580 --- 3.0.49 2009/10/01
582 Make a number of functions defined in xmlquery.c static. These have
583 never been declared in a public header file (yaz/xmlquery.h) and was
584 made public by mistake.
586 Improve speed of character conversions (iconv utilities). This makes
587 conversions from MARC-8 faster.
589 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
590 unless type desired is "raw". This will prevent type "xml" from
591 returning ISO2709 .. Which obviously can not be XML parsed.
593 Fix memory leak in ZOOM that would occur if option apdulog was used
594 on a re-used connection.
596 Frontend server logs HTTP requests.
598 Frontend server now sends Z39.50 close when it times out (sesssion has
599 been idle for too long). Versions 2.0.30 and earlier also sent close.
600 But due to a mistake this was disabled in all versions after that, i.e.
601 the server would just close the socket immediately.
603 yaz-client emits a better message when receiving an unrecognised
604 userInformationField.
606 Skip zero-length subfields when decoding ISO2709. This rare case happens
607 if a record has two FS characters in a sequence. Without this patch
608 there would be a reference beyond char array in using_code_len fragments
611 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
613 --- 3.0.48 2009/08/28
615 The show command offered by the zoomsh command now takes a 3d optional
616 parameter type which is what is passed to ZOOM_record. If the type
617 argument is omitted, "render" is used.
619 RPN to CQL conv may use USE string attributes (bug #2978).
621 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
623 --- 3.0.47 2009/07/08
625 Function yaz_xml2query allows a diagnostic element in the PQF XML
626 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
627 code and additional info respectively.
629 The BER BOOLEAN is now the integral type Odr_bool which still happens
630 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
631 typedef'd to Odr_int. This is still an integral 'int', but it may be
632 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
633 ASN-1 compiler as well as programs has been updated to use the new types.
635 --- 3.0.46 2009/06/08
637 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
638 only the bibliographic record was rendered. For type=opac, an OPAC
639 record is only returned if it is present.
641 iconv: small fix for encoding of advancegreek.
643 yaz-client: avoid double display of SRU/SRW records (bug #2798).
645 yaz-client: option auto_reconnect=on really reconnects.
647 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
649 server: avoid null ptr ref for for yaz_poll errors.
651 build: fix RPM build for RHEL 5.3.
653 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
655 --- 3.0.45 2009/03/31
657 Fixed bug #2709: TCP connect returns Invalid argument.
659 Fixed compilation for mingw.
661 Honor charset for raw records (ZOOM_record_get).
663 Fixed use of errno for threaded mode that was seen on Solaris 10.
665 Fixed argument passing with blanks in value for Windows Service.
667 Disable YAZ' own log rotate by default (no 1 GB limit).
668 The variable l_max_size which specifies the log file limit is set to 0
669 (DISABLED): This is due to the fact that YAZ is most often deployed using
670 logrotate. Also YAZ can not perform log rotate because of unsufficient
671 permissions (setuid).
673 --- 3.0.44 2009/02/17
675 List supported encodings in man page for yaz-iconv.
677 Fixed missing SSL libs for --libs output
679 Re-established OID record syntax application-xml. Nobody should use it
680 but we don't want to change soname because of this symbol being absent.
682 --- 3.0.42 2009/02/02
684 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
686 Added member named_result_sets for init handler struct for the GFS. This
687 allows a server to disable named result sets.

711 --- 3.0.41 2008/12/29
713 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
715 --- 3.0.40 2008/12/29
717 For configure, using option --without-xml2 also disables Libxslt/Libexslt
720 Fixed bug #2352: yaz-marcdump crashes for certain record.
722 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
724 Added support for Danmarc2 to UTF-8 conversion.
726 Added support for ISO5426 to UTF-8 conversion.
728 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
729 implementation version.
731 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
733 --- 3.0.38 2008/11/10
735 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
736 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
738 ZOOM C now interprets databaseName option for ZOOM connection as path
741 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
743 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
745 Dummy Libxml2 types no longer defined in headers of YAZ'.
747 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
750 --- 3.0.36 2008/09/26
752 Various ODR chapter fixes.
754 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
756 Added missing source for Windows compilation, mutex.c.
758 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
760 For SRU connections in ZOOM all records up to "count" are now fetched.
762 Fixed crash in generic frontend server (and yaz-ztest) which occurred
763 in Windows due to bad error handling for Libxml2.
765 Added facility for sending arbitrary records (ASN.1 any) using
766 ZOOM C's Extended service update. Patch by Sam Reynolds.
768 New options for ZOOM C's connection, logapdu which makes ZOOM log
771 --- 3.0.34 2008/06/18
773 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
775 --- 3.0.32 2008/06/12
777 Fixed memory violation that could occur when decoding UTF-8. This bug
778 was only present in 3.0.30 of YAZ.
780 --- 3.0.30 2008/06/06
782 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
783 GNU TLS is used by default (if found).
785 yaz-ztest returns OPAC records if a client asks for OPAC.
787 Improved speed of MARC-8 encoding.
789 Added support for lossy and loss-less MARC-8 encoding.
791 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
793 Added new Windows Service wrapper (sc).
795 yaz-client's itemorder command may now send a file.
797 Fixed yaz-marcdump to allow the use of NS prefix for record element.
799 Added new function yaz_log_xml_errors.
801 Allow (but warn) unknown XML attributes in MARCXML parsing.
803 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
805 The UTF-8 to MARC-8 conversion now uses a different set of characters
806 for Greek symbols. Bug #2120.
808 --- 3.0.26 2008/02/21
810 Added yaz_daemon (daemon.h).
812 Fixed bug #2068: pkg-config trouble
814 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
816 --- 3.0.24 2008/01/28
818 Document --with-xml2 option.
820 Added OPAC XML XSD (etc/opacxml.xsd).
822 Allow glob mask for name attribute in retrieval element for the
823 generic frontend server's retrieval facility.
825 Changed yaz_poll_poll to return yaz_poll_except for all returned events
826 except POLLIN/POLLOUT.
828 Fixed error handling in cs_listen. Bug #2037.
830 --- 3.0.22 2008/01/20
832 Fixed version in yaz/yaz-version.h.
834 Fixed bug #2027: Crash when closing connection.
836 Changed configure so that ICU support is only enabled if only ICU
837 and Libxml2 is available (because the ICU chain is XML based).
839 --- 3.0.20 2008/01/15
841 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
842 is built. Only this DLL depends on the ICU runtime.
844 yaz-ziffy is no longer part of YAZ. It is distributed separately by
845 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
847 Changed license of CCL module to 'Revised BSD'. After consultation with
848 remaining members of the original EUROPAGATE consortium, we are re-issuing
849 the CCL module without a separate license. The software was developed by
850 Index Data as part of a research project. The special license was included
851 to help feed usage information back to the project consortium to support
852 project evaluation. At this time, the project consortium has long-since
853 disbanded, and the majority of the original principals have retired. At the
854 same time, we have significantly modified the software during the following
855 years, to the point where very practically no original code remains. To
856 simplify re-use of the software, we have contacted those members of the
857 consortium who could be reached, and agreed to re-issue the module as a
858 proper part of the YAZ package.
860 Tcl scripts uses /usr/bin/tclsh as preferred shell.
862 CQL closer to being version 1.2 compliant. CQL also allows free-form
863 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
866 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
867 bug could make Extended services handling crash in the ZOOM layer. This
868 bug was only present in YAZ 3.0.18.
870 --- 3.0.18 2007/12/19
872 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
875 yaz-marcdump reads and writes collection wrapped records.
877 Handle OPAC for record conversion module.
879 Fixes for ICU wrapper.
881 Allow ICU libs to be controlled with --with-icu .
883 --- 3.0.16 2007/11/12
885 Added yaz_poll which is a wrapper for select/poll. When poll is available
886 and non-buggy, it is used, by yaz_poll . This allows more than 1024
887 sockets to be in use.
889 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
890 functionality through an XML based configuration (ICU chain). This system
891 is useful for search facilities such as Pazpar2 and Zebra that needs to
892 perform tokenization of indexed material. The ICU code in a separate
893 library libyaz3_icu.a.
895 Added HTTP tunnel facility for COMSTACK, bug #1752.
896 This is a facility that allows a Web proxy, such as squid, to tunnel
897 Z39.50 traffic. This facility is "transparent" to must applications
898 using YAZ. It's enabled by using pseudo transport connect: followed by
899 the proxy address, followed by command, then follwed by he regular
900 "virtual" addresss. For example,
901 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
903 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
905 --- 3.0.14 2007/09/21
907 Fixed bad memory reference in ZOOM_record - cuased by member not being
908 initialized. This was a problem only in YAZ 3.0.12.
910 Fixed bug in conversion from MARC to XML: Non-XML characters in control
911 fields were not removed.
913 Changed the way C code is generated from codetables.xml. Made a MARC-8
914 conversion trie for each characterSet section rather than codeTable.
915 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
916 of codetables.xml from Larry Dixson, LOC. Bug #1464.
918 --- 3.0.12 2007/09/12
920 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
921 from ZOOM_record_error).
923 ZOOM C function ZOOM_record_get returns record schema for type="schema".
925 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
927 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
929 Better SRW-to-Bib-1 diagnostic mapping.
931 ZOOM C and yaz-client announces SRU version 1.2 by default.
933 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
936 Fixed in yaz_sru_decode to allow other version than 1.1.
938 --- 3.0.10 2007/08/22
940 Added support for SRU scan for ZOOM.
942 Added support for the use of the older versions or Extended Service
943 Update in ZOOM. To faciliate this, an option "updateVersion" may be
944 set to the version , 1=first, 2=second, 3=third. The third version is
945 what ZOOM C has used so far. And that, obviously, is the default.
947 Added support for CCL queries in Z39.50 queries sent to the GFS (and
948 therefore in Zebra and in SimpleServer-based applications). The new
949 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
950 qualifier file used to transform incoming CCL queries into Type-1 RPN,
951 which is passed into the back-end search callback function.
953 Added support for HTTP Basic authentication in clients: the SRU/W
954 codec encodes the username/password elements of the PDU structure
955 appropriately, and these may be set using the "user" and "password"
956 options in ZOOM-C applications (the same options that are used for
957 Z39.50 authentication).
961 Fixed bug #1208: SSL appears to be broken in ZOOM.
963 Fixed bug #1206: Libxml2 include path weirdness.
965 Added oid_name_to_dotstring.
967 Allow elementSetName to be specified for ZOOM C record update.
969 Allow waitAction to be specified for ZOOM C based for Extended Services.
971 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
972 syntax OID. Bug introduced in YAZ 3 series.
974 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
978 Fixed bug #1157: yaz-client does not read .yazclientrc from current
979 directory. yaz-client now reads commands from file given by option -f
980 if specified; then tries to read .yazclientrc in current directory.
981 Failing that, it reads .yazclientrc from user's home directory.
983 Added support for correlationInfo Note and ID for Record Update via
986 Added yaz-client command querycharset which specifies character set for
987 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
988 (termListAndStartPoint).
990 Charset ISO5428:1984 is an alias for ISO5428-1984.
992 Implemented a way to perform scan in a result set using Z39.50. This
993 is achieved by attaching the result set name in the characterInfo
994 (type InternationalString) of OtherInformation in the Scan Request PDU.
995 The result set is identified in the otherinformation by the new OID:
996 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
997 This allows for scan in result set and faceted search . Zebra did some
998 of this in the APT term using attribute type 8 and value being result
999 set. Using the OtherInformation approach for this is cleaner and easier
1000 to work with in proxies and the like. This facility can be used in
1001 yaz-client using new command setscan which takes a result set as first
1002 argument, start position (APT) as second.
1004 Changed decoding of SRU XML packed records to deal with servers that
1005 have recordData with XML data with multiple root nodes. Also make
1006 comparison for recordPacking case insensitive. Again, one server
1007 returns "XML" where others return "xml".
1009 For SRU responses allow Content-Type application/xml as well as text/xml.
1011 --- 3.0.4 2007/05/21
1013 Fixed bug in character set conversion of BER strings. Bug introduced
1016 --- 3.0.2 2007/05/08
1018 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1020 For OID class, use oid_class consistently.
1022 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1025 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1026 character set for bibliographic information interchange". By Giannis Kosmas.
1028 Added documentation on new OID API.
1030 --- 3.0.0 2007/05/02
1032 Changes to generic frontend server interface: added new member
1033 'query_charset' for bend_initrequest structure. A backend init handler
1034 should set this member to its native character set for query terms.
1035 When defined, the frontend server logic will announce this character set
1036 to a client if the negotiationModel bit is set by the client. All server
1037 implementors are encouraged to specify this. If a backend server does not
1038 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1040 Added CCL utility to remove terms (stop words) from resulting RPN
1041 tree. This is handled by functions with prefix ccl_stop_words_ .
1043 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1044 terms in RPN queries.
1046 Clean-up the CCL API. Moved some internal structures from ccl.h to
1047 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1048 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1049 This is replaced by ccl_parser_find_str which takes a string instead.
1051 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1052 libyaz.la is the core of YAZ except the generic frontend server and
1053 does not depend on POSIX threads anymore. libyaz_server.la is the
1054 generic frontend server facilities and uses POSIX thread functionality
1055 if available. The libyaz.la no longer depends on POSIX threads because
1056 the number of global structures is limited. NMEM no longer re-uses blocks
1057 between threads ; it simply free's memory immediately but allocates in
1058 "large" chunks as usual. We don't expect any performance penalties
1059 because of this. The yaz_log system is still using a global log_level so
1060 caution must be taken when modifying it with yaz_log_init_.. +
1061 yaz_log_mask_str. This, however, should not cause any trouble because
1062 these functions are called during initialization of application code
1063 anyway. `yaz-config --libs server` returns libs for server applications;
1064 `yaz-config --libs` returns libs for non-server applications.
1066 New OID database - with public definitions in oid_db.h. Removed old OID
1067 database including the head oid.h and definitions such as enum oid_value
1068 and struct oident. The new OID database uses the same string names as
1069 before but the 'protocol' is gone. There are now only two representations
1070 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1071 converts from string to OID; functions with prefix yaz_oid_to_string
1072 converts the other way.
1074 Change to emit_term() in CQL-to-PQF query translation: when a term has
1075 the /regexp relation modifier, do not process it for leading and
1076 trailing "^" and "*", which have quite different meanings in regular
1079 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1080 write handlers no longer carries a 'last' parameter. This will make
1081 yaz_iconv flush "less" characters. A flush is performed by call to
1082 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1084 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1085 removed, because function yaz_query_to_wrbuf does the same.
1087 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1088 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1090 Deprecated MARC utility functions removed.
1092 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1095 Branch split: YAZ_2_1_55_branch
1097 --- 2.1.54 2007/03/16
1099 Fix to ZOOM-C so that transparent reconnection is properly handled on
1100 connections that are in asynchronous mode.
1102 Fixed compilation on OpenBSD 4.0.
1104 Large strings in GRS-1 records are now properly displayed in yaz-client.
1106 Added character conversion support for "advancegreek"; based on patch from
1109 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1110 sequence is met. Before the error was not set so it would be unknown.
1112 Adjust yaz-marcdump MARC reader so that it skips until record separator
1115 --- 2.1.52 2007/03/07
1117 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1118 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1119 fd_set structure used as a bitmask for the FDs to be selected on.
1121 Using ACX_PTHREAD macro to check for POSIX threads.
1123 Fixed have-vsnprintf check.
1125 --- 2.1.50 2007/02/23
1127 Fixes for configure on BSD. Bug #900.
1129 Added snprintf/vsnprintf wrappers for systems that don't have
1130 limits (heavens forbid).
1132 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1133 created before all previous tasks were completed and removed from the
1134 task queue, the new task could be removed by a mistake.
1136 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1138 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1140 Fixed bug #832: Problem with MARC/charset in yaz-client.
1142 Fixed bug #668: save command line history for yaz-client.
1144 Fixed bug #830: pkg-config support.
1146 --- 2.1.48 2007/01/23
1148 Extended ZOOM result set options with two options that may be read by
1149 a client: resultSetStatus and presentStatus with values as specified for
1151 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1153 Fixed bug #827: Using SSL fails on Debian etch.
1155 Fixed bug #826: Weird looking chars for set of MARC records.
1157 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1158 that is treated as an ItemOrder with itemRequest being an XML document
1159 external. The value of "doc" is the content.
1161 Extended the GFS search facility. New member of bend_search_rr
1162 'estimated_hit_count' signals that hits is known to be an estmate
1163 (higher or lower than real hit count). New member 'partial_resultset'
1164 signals that the search was partial (hit count is lower or equal than
1165 real hit count). For Z39.50, the information is stored in resultSetStatus
1166 member of SearchResponse APDU. For SRU, the information is signalled
1167 via SRU diagnostic 59: "Result set created with valid partial results
1170 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1172 --- 2.1.46 2007/01/13
1174 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1176 Added ZOOM_connection_peek_event.
1178 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1179 the following new functions:
1180 ZOOM_event_nonblock, ZOOM_connection_process,
1181 ZOOM_connection_get_{socket,mask,timeout},
1182 ZOOM_connection_fire_event_{timeout,socket}.
1183 The existing blocking event handler, ZOOM_event, is a wrapper for the
1184 + blocking ZOOM_event_sys_{poll,select}.
1186 Implemented function ccl_xml_config which parses XML version of CCL
1187 configuration (bug #798).
1189 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1191 Added timings utility (yaz/timing.h)
1193 --- 2.1.44 2007/01/03
1195 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1198 Fixed bug #779: Rotation of apdu.log fails.
1200 Fixed for character set conversions:
1201 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1202 Honor G1 set in MARC-8 decoding.
1204 --- 2.1.42 2006/12/17
1206 Fixed bug #775: char conversion does not handle Alternative UTF-8
1209 Implemented function yaz_marc_read_line which parses MARC line format
1210 records. There is a wealth of formats out there. So far, this function
1211 reads line records produced by yaz_marc_write_line.
1213 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1214 more generic and easier to remember(!) options: -i format and -o format
1215 which specifies input format and output format respectively - where
1216 format is one of "marc", "marcxml", "line", "marcxchange".
1218 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1219 does not print anything except warnings for records.
1221 For yaz-marcdump, added support for MARC split into files (-s) with a given
1224 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1225 spec, at http://www.loc.gov/standards/sru/record-update/
1226 This has changed the binary layout of the following structs:
1227 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1228 bend_update_rr . Patch by Ko van der Sloot.
1230 Added GFS utility function bend_assoc_is_alive which returns 1 if
1231 association is still alive (client is connected); 0 otherwise (client
1232 closed connection). This allows busy servers to stop working for
1235 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1236 been a separate piece of software. This version of ziffy has been modified
1237 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1239 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1241 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1242 Client code may now interrogate options such as "init_opt_sort" to
1243 find out whether the server claims to support various options.
1245 --- 2.1.40 2006/11/27
1247 Added utilities yaz_{set,get}_esn to set/get element set name from
1250 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1251 of YAZ and has been so since YAZ 2.1.10.
1253 Implemented ZOOM_record_error which returns error information for
1254 record (surrogate diagnostic).
1256 --- 2.1.38 2006/10/31
1258 Updates for SRU Update by Ko van der Sloot:
1259 1. Changed name from "operation" to "action"
1260 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1261 versions in the code, marked as 'backward compatible'.
1262 3. Added diagnostics for SRU Update.
1264 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1266 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1268 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1270 For GFS, fixed problem with SRU diagnostic 'First record position out of
1271 range' being issued for 0 hits.
1273 zoomtst10 part of Windows Build.
1275 --- 2.1.36 2006/10/13
1277 Implemented yaz_filepath_comp which splits a path into file path
1278 components (required by Zebra 2.0.3+).
1280 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1281 BSD inspired license until now so this should not have any real impact on
1282 anybody. See http://www.opensource.org/licenses/bsd-license.php
1284 Fixed bug #687: Missing log lines.
1286 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1289 Fixed bug #689: SRU diagnostics to be added.
1291 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1292 whether a connection is idle (no more work do do).
1294 --- 2.1.34 2006/10/04
1296 Change type of optval from long to int for invocation of setsockopt with
1297 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1299 Added support for specifying the max log file size for the Generic
1300 Frontend Server. The size is given with option -r.
1302 --- 2.1.32 2006/09/21
1304 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1306 --- 2.1.30 2006/09/17
1308 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1311 Fixed bug in Generic Frontend Server that could cause a server to stop
1312 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1314 For the generic frontend server, the maximum record size is used as maximum
1315 size of incoming packages (SRU + Z39.50). The value until was previously
1316 only used in Z39.50 Init negotiation and, later, in a session controlled
1317 sizes of records returned. This is controlled using -k option. It can be
1318 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1320 --- 2.1.28 2006/09/04
1322 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1325 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1327 New option for yaz-marcdump -lpos=value which allows setting a portion
1328 of MARC header to a certain value.
1330 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1332 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1333 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1335 --- 2.1.26 2006/08/15
1337 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1340 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1342 --- 2.1.24 2006/08/08
1344 Fixed MARC ISO2709 encoding routines to deal with character set
1347 Minor changes to GFS logging. Database included in search request log
1350 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1351 cached/multiple records.
1353 Shared libraries are built by default on Unix+configure.
1355 Changed cql2pqf transformation to use a different evaluation order. The
1356 new order is: always, relation, structure, position, truncation, index
1357 and relationModifier. Old order was: always, relation, relationModifier,
1358 structure, index, position, truncation. Note that the the latter ones
1359 override former ones for identical attributes.. The new scheme means that
1360 it is possible to override any existing attribute with a relationModifier.
1361 And also that it is possible to override everything for the index rule
1362 (except the ones listed in relationModifier). No order is perfect but this
1363 one, we believe, covers more real cases.. The "always" should have been
1364 called "default", since the attributes there can be overridden with all
1367 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1368 compilation phase, but also for yaz-config --cflags output. This allows
1369 us to have public headers with Libxml2 stuff in them . It should also,
1370 eventually, make Libxml2 checks redundant in packages using YAZ, such
1373 --- 2.1.22 2006/06/15
1375 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1376 stored in uri, message and details.. Previously diagnostics were stored
1377 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1378 compatibility.. but he's probably the only one affected, so.
1380 Added support for CCL, compiled on the client side, in ZOOM-C. This
1381 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1382 input; the resulting query objects can be used for for searching with
1383 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1385 YAZ' configure searches for OpenSSL by default.
1387 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1388 SL_CTX_use_certificate_file. See
1389 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1390 for more info. Thanks to Ko van der Sloot.
1392 --- 2.1.20 2006/06/02
1394 Bug #600: SRU GET, POST support for yaz-client. Introduced
1395 command 'sru' which selects method SOAP/GET/POST.
1397 Allow missingValueAction to be specified for the sortspec string -
1398 function yaz_sort_spec. By default, the missing value action is null.
1399 Use ! to specify "abort". Use = followed by stringvalue to specify default
1402 Ensured that Present-handler (if defined) is called in GFS before any call to
1403 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1404 searchRetrieve requests.
1406 Documentation for YAZ is now based on the Docbook XML/XSLT using
1407 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1408 is no longer depending on jade/openjade or docbook-to-man scripts.
1409 PDF is no longer part of the distribution - but can optionally be
1410 made using DSSSL/jadetex or FOP.
1412 Added retrieval handling support in Generic Frontend Server to support
1413 conversion between MARC/XML as well as XSLTtransforms. See
1414 etc/yazgfs.xml for an example.
1416 Added Authentication support to Generic Frontend Server in SRU
1417 mode. Authentication using HTTP Basic is supported, as is the use
1418 of 'x-username' and 'x-password' parameters in the request itself.
1420 Added support for a new character set MARC8s identical to MARC8 except
1421 that it converts combined characters to single Unicode characters in the
1422 Latin-1 range (when possible).
1424 --- 2.1.18 2006/04/24
1426 ASN.1 compiler 0.4: generates brief Doxygen file header for
1427 generated .h/.c files.
1429 Utility yaz_iconv now supports conversion to MARC-8.
1431 New facilities for the MARC module. The reading - and writing of
1432 content are separate methods for the yaz_marc_t handle. The following
1433 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1434 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1435 format). Write functions have prefix yaz_marc_write_.. The existing
1436 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1437 available. Removed support for OAI-MARC and simplexml (not the
1438 simplexml from PHP5).
1440 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1441 to be returned for this connection.
1443 --- 2.1.16 2006/03/31
1445 Allow multiple languages and charsets to be specified with
1446 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1447 negcharset iso-8859-1,utf-8
1449 Translation of proximity nodes from CQL into PQF now works.
1451 Moved to automake 1.8, 1.9.
1453 Added function yaz_log_set_handler which allows a log handler to be
1454 installed. This handler will be called for all log messages. Output
1455 to file is also produced; but that can be disabled by passing NULL
1456 fname to yaz_log_init_file.
1458 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1460 For SRW (including GFS), accept application/soap+xml as content-type
1463 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1464 produces NO stylesheet reference even if a default stylesheet is specified
1467 --- 2.1.14 2006/03/14
1469 Updated Windows package to include yazd.dll + yazd.lib for the
1470 Development component.
1472 If the environment variable YAZ_LOG is set, then it is used as a
1473 string indicating the default level of logging to use if not
1474 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1475 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1476 used as before. So, for example, to omit warnings from YAZ logging,
1477 export YAZ_LOG=-warn
1479 cql_transform() now map structure and other attributes before indexes,
1480 so that index-specific structures and other attributes can override
1481 defaults. So now a combination of mapping specifications such as:
1483 index.dc.date = 1=date-modified 4=5
1484 does the right thing.
1486 cql_transform() now also respects the "always" mapping specification,
1487 which establishes an initial set of attributes to be used for all
1488 terms except where overridden by more specific attributes associated
1489 with the index, relation or modifier.
1491 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1492 which mode to use; one of "post", "get" or "soap" (SRW, default).
1494 Fixes for yaz_iconv routines: changed trie-based character set conversions
1495 to use only non-negative values for bit fields due to Sun's C compiler not
1496 supporting negative values.
1498 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1499 sequences where not read correctly. Fix by Rustam Usmanov.
1501 Updated win/makefile to use options, settings which makes things
1502 compile with VS C 2005.
1504 --- 2.1.12 2006/02/01
1506 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1508 In ZOOM socket code, use select instead of poll on MacOSX.
1510 ZOOM-C now support client-side compilation of CQL into RPN that is
1511 sent to the server, enabling CQL to be used against all Z39.50
1512 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1513 ZOOM_query object, and submit it using ZOOM_connection_search().
1514 The CQL-to-RPN translation uses a configuration file, the name of
1515 which must be specified in the Connection's "cqlfile" option.
1517 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1518 function, which takes as its start-term parameter a ZOOM_query object
1519 (which may have had either CQL or RPN set into it).
1522 --- 2.1.10 2005/11/29
1524 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1525 GFS to support this as well. Backend handler, bend_srw_update, does the
1526 update work. Code contributed by Ko van der Sloot.
1528 Allow retrieval of Search Result-1 information in ZOOM by the use of
1529 options that are attached to a result set. ZOOM documentation updated
1532 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1533 UTF-8 conversion. Patch by Raj Patel.
1535 Added option -m to GFS to control formatting of timestamps in log file.
1537 Added 'exit' as synonym for 'quit' in yaz-client
1539 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1540 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1541 for the new members. Patch by Ko van der Sloot.
1543 Added support for SRU POST. It is supported for content-type
1544 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1546 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1547 Instead make the library libyaz.la multi-threaded. Threading as a whole
1548 can still be disabled by configure option --disable-threads. Previosly,
1549 with older GLIBCs there were problems with MT libs under Apache. This
1550 has now been fixed a long time ago.
1552 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1555 CQL module modified to be case insensitive for relations/indexes/operations.
1557 Fixed bug in CQL transform code: incorrect value relationModifieder
1560 Added 'show all' command for yaz-client which retrieves all results
1563 Added new yaz-client, xmles, which takes a (private) OID and
1564 a document to be sent as an extended service request.
1566 Describe new yaz-client commands wait_response and set_auto_wait.
1568 Increase TCP/IP listener backlog from 3 (which I am guessing was
1569 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1570 that the socket will queue as many incoming connections as it's able
1571 to handle ongoing connections. In other words, it will never now
1572 refuse a connection that it would be able to handle merely because
1573 it's not got around to accepting() enough of the pending connections
1574 yet. This is the behaviour anyway under Linux, where the listen()
1575 argument is ignored; but not under BSD and on systems such as
1576 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1577 YAZ-based servers should now be uniform across operating systems in
1580 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1581 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1582 This allows yaz-marcdump to read large MARC batches (>2 GB).
1584 Modified all YAZ source files - except the source which is auto-generated
1585 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1588 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1589 corresponding to the existing *_setl() function. These allow option
1590 values containing arbitrary valuues.
1592 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1593 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1594 except that it returns an indicator of whether or not the sort
1595 criterion was accepted (0 for OK, -1 for invalid).
1597 --- 2.1.8 2005/06/07
1599 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1600 MARC output rather than returning "new" buffer.
1602 yaz-client warns about unknown init options.
1604 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1606 --- 2.1.6 2005/05/24
1608 Added support for SRW sort in Generic Frontend Server. Patch
1609 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1610 sortKeys - or NULL if none is provided.
1612 Fixed bug #307: It was impossible to specify indefinite/no timeout
1613 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1616 Added support for multiple languages and charsets to be specified in
1617 ZOOM. Each charset/language is separated by a blank. If negotiation is
1618 in effect in init-response, Option
1619 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1620 Code based on patch by Vasiliy Osadchuk.
1622 Fixed bug #306: infinite recursion that occurred when calling
1623 yaz_log_level_init as the first call (before other log level or
1626 Fixed bug in scan handling in front end server: if preferred-Position-In-
1627 Response was non-present, a NULL pointer referece was performed.
1629 --- 2.1.4 2005/04/26
1631 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1632 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1633 now defined for all those error codes. So instead of putting 109 in
1634 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1635 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1637 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1640 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1642 Program yaz-client now exits and produces an error message if multiple
1643 Z39.50 servers are specified on the command line (none or one allowed
1646 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1649 --- 2.1.2 2005/03/16
1651 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1653 Fixed bug #272: Preserve spacing for CCL terms.
1655 --- 2.1.0 2005/03/14
1657 Added support for virtual hosts and multiple backend servers for
1658 the YAZ frontend server. The configution is XML based and
1659 support specificition of CQL to RPN mappings and explain information.
1660 See section "Virtual Hosts" in the YAZ manual.
1662 Extended OPAC display utility. OPAC display utility renders
1663 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1664 to supplement yaz_marc_decode_wrbuf.
1666 Fixed a bug in MARC decoder that could caused it to crash for some
1667 invalid MARC records. More diagnostics and warnings where added in
1668 XML output (warnings, etc are stored in comments).
1670 --- 2.0.34 2005/02/08
1672 Fixes for UNIX domain sockets. Bug #261.
1674 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1676 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1677 Added yaz_marc_subfield_str which defines subfield lead string which is
1678 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1679 yaz_marc_endline_str which defines end of fields string used in
1680 YAZ_MARC_LINE format. Default string is newline.
1682 Experimental support for MarcXChange. This format can be produced
1683 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1684 http://www.bs.dk/standards/MarcXchange.xsd
1686 Added yaz-client commands scansize that sets maximum number of
1687 entries to be returned by scan.
1689 --- 2.0.32 2005/01/11
1691 Added support for SRW scan in yaz-client and Generic Frontend Server.
1693 * Added whereInList member to SRW Scan Term.
1695 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1697 Fixed NMEM system to return aligned blocks on the smallest boundaries
1698 that are suitably aligned for all possible types on the particular
1699 architecture YAZ is being built for.
1701 --- 2.0.30 2005/01/04
1703 Fixed numerious warnings that was issued with newer versions of GCC.
1705 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1706 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1709 Make YAZ Generic Frontend Server slightly faster.
1711 Enhance (and reduce) logging for Generic Frontend Server.
1713 Revert YAZ log system so that it flushes every write operation
1714 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1716 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1717 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1718 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1719 will effectively disable old definitions.
1721 --- 2.0.28 2004/11/09
1723 Added yaz_log_time_format which specifies log format using
1726 Added yaz_log_module_level which returns mask for a module. Value
1727 is non-zero mask a if module is enabled; zero if disabled.
1729 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1730 in include/yaz/cql.h.
1732 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1734 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1736 Fixed bug #172: RPM builds does not enable SSL.
1738 Doxyfile.in part of dist. Doxyfile generated by configure.
1740 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1741 are given and the corresponding component does not exist.
1743 Extend CCL documentation in YAZ reference. Describe r=r.
1745 --- 2.0.26 2004/10/01
1747 Fixed MARC->MARCXML conversion to properly deal with
1748 fields, subfields, indicators having non-ASCII characters.
1750 Fixed MARC->MARCXML conversion so that ASCII control characters
1751 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1754 Added YAZ GFS support for conversion from Z39.50 surrogate
1755 diagnostics to SRW surrogate diagnostics.
1757 Bug fix: YAZ GFS did not return schema in explainResponse.
1759 --- 2.0.25 2004/09/30
1761 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1762 now converts recordSchema to elementSetName as well as schema URI.
1764 Fixed bug in COMSTACK that prevented HTTP request packages from being
1767 --- 2.0.24 2004/09/29
1769 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1770 does not require white-space before and after the dash in a range, e.g.
1771 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1774 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1775 due to new GCC removing "redundant" code.
1777 Added yaz-client commands scanpos and scanstep that sets preferred
1778 position and step-size for scan.
1780 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1782 Added CCL utility ccl_qual_buf which parses one or more CCL
1783 spec lines in a buffer.
1785 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1786 of name and value - ignoring empty lines and comments.
1788 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1790 Added odr_get_element_path which returns current element path for an
1791 ODR handle. This utility is useful in error handling or user-defined
1794 Added ODR_PRINT utility odr_set_stream which is is a more generic
1795 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1796 to a write function and pointer to close function. The close function - if
1797 non-NULL - will be called during odr_destroy.
1799 Fixed bug in CCL parser where truncation char was not removed from
1800 right side when truncation=both was in effect.
1802 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1805 --- 2.0.23 2004/08/11
1807 Fix buffer overrun in CQL parser when dealing with proximity (%).
1809 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1810 to UTF-8/UCS conversion is now only based on codetables.xml.
1812 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1814 --- 2.0.22 2004/08/06
1816 Add support for more "commit changes" in ZOOM (uses Extended Services).
1818 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1821 Yet another small fix for configure of SSL.
1823 --- 2.0.21 2004/05/14
1825 Fix SSL libs for configure when --with-openssl=DIR is given.
1827 --- 2.0.20 2004/05/10
1829 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1831 SSL comstack now uses yaz.pem certificate file on server side
1832 by default. Certificate filename can be configured by calling
1833 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1835 Fix bug regarding multiple calls to ZOOM_connection_connect.
1837 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1839 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1840 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1842 ZOOM now allows inspection of X509 peer certificate for verification.
1843 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1845 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1846 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1847 as "modular" but it simplifies things.
1849 Added cs_get_peer_certificate to that returns peer X509 PEM.
1851 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1852 NULL if SSL is unavailable.
1854 Documentation about MARC decoding tools.
1856 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1858 --- 2.0.19 2004/03/30
1860 Rename CHANGELOG to NEWS to follow GNU style packing.
1862 Fix bug with missing initialization of member in init_diagnostics.
1863 This bug affects threaded version of GFS server.
1865 --- 2.0.18 2004/03/20
1867 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1870 Ensure zlib.dll is packed with Windows install.
1872 --- 2.0.17 2004/03/17
1874 Fix encoding of xsd:string to use text instead of CDATA.
1876 Fix endless loop in CQL parser with unbalanced ".
1878 Use a more compact way to store MARC-8 conversion tables.
1880 --- 2.0.16 2004/03/16 Debian only
1882 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1885 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1890 --- 2.0.15 2004/03/01
1892 Another fix for decoding of XML packed records.
1894 --- 2.0.14 2004/02/25
1896 Fixes for Chunked encoding. White space not ignored after length spec.
1898 Update NS and use default NS for SRW diagnostic elements.
1900 --- 2.0.13 2004/02/23
1902 Implement ZOOM_resultset_cache_reset which resets record cache.
1904 Implement ZOOM_resultset_sort which sorts a result set.
1906 Implement chunked HTTP transfer.
1908 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1910 --- 2.0.12 2004/02/16
1912 Added member 'schema' to bend_explain_rr structure so that backend
1913 can specify explain record identifier. Defaults to Zeerex 2.0.
1915 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1917 --- 2.0.11 2004/02/16
1919 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1922 Added init command for yaz-client which sends "extra" init request.
1924 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1925 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1927 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1929 Make ZOOM error code for "invalid query".
1931 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1933 --- 2.0.10 2004/02/05
1935 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1938 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1940 Added option -p <file> to make Generic Frontend Server to write PID file.
1942 Added option -D to put Generic Frontend Server in background on its own.
1944 Make ZOOM C recognize option "password". If unset, "pass" is used
1945 (for backwards compatibility).
1947 Fixed a bug in Generic Frontend Server that could make it crash if a
1948 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1951 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1952 Must be issued before open, in order to be in effect.
1954 --- 2.0.9-6 2004/01/12 Debian/Windows
1956 Make the SRU server more picky WRT unknown params, etc.
1958 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1960 New YAZ client command, options, that sets Z39.50 options.
1962 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1963 options from a string of tokens (one token for each option bit).
1965 Update SRW diagnostic code messages.
1967 --- 2.0.9-5 2004/01/07 Debian/Windows
1969 Handle user defined stylesheet for SRW/SRU.
1971 --- 2.0.9-4 2004/01/06 Debian/Windows
1973 Fix bug in decoding of Content-Length.
1975 --- 2.0.9-3 2004/01/06 Debian/Windows
1977 Fix a bug with decoding of XML packed records.
1979 --- 2.0.9-2 2004/01/05 Debian only
1981 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1983 Fix bug in SRW/SRU diagnostics decoding.
1985 --- 2.0.9 2004/01/05
1987 Fixed bug in Generic Frontend Server which could drop records exceeding
1988 preferred message size. Reported and fixed by Irina Dijour.
1990 Fixed calculation of package size for structured records in Generic
1991 Frontend Server. Reported and fixed by Irina Dijour.
1993 Fixed namespace for SRW/SRU diagnostics.
1995 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1997 --- 2.0.8 2003/12/22
1999 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2000 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2003 CQL changes to reflect recent changes to the specification:
2004 * Documentation talks about context sets instead of index sets.
2005 * Documentation talks about indexes instead of qualifiers.
2006 * The CQL-to-PQF transformer's configuration file now uses
2007 "index.set.name = <attributes>" instead of the old form
2008 "qualifier.set.name = <attributes>". (Both forms are still
2009 understood but the latter is deprecated.)
2010 * CQL terms with no explicit index specified are now interpreted as
2011 cql.serverChoice instead of srw.serverChoice (which of course
2012 behaves exactly the same.)
2014 --- 2.0.7 2003/12/16
2016 MARC conversion can now generate ISO2709 output in another
2017 character set. yaz-marcdump uses this facility if you invoke it
2020 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2021 functions from there can be used from C++.
2023 --- 2.0.6 2003/12/04
2025 Frontend server now transfers memory from decoded packages to stream
2028 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2029 references to show up.
2031 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2032 the ZOOM Abstract API. The older names for the same options are still
2033 also supported for the benefit of old applications.
2035 ZOOM-C supports "implementationId" and "implementationVersion" options
2036 to go along with "implementationName". These allow the user code to
2037 specify identification strings to be sent to servers.
2038 Add OID for the new ExtLite attribute set.
2040 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2041 as requested/supplid by Ere Maijala <ere@atp.fi>
2043 For generic frontend server, reverse the order of
2044 "toolkit-supplied / application-supplied" strings sent as implementationId,
2045 Name and Version. Also, remove the spaces around the slash. This brings
2046 the GFS in line with the behaviour of ZOOM-C on the client side.
2048 Add function ZOOM_scanset_display_term.
2050 yaz-client shows scan displayTerm if present.
2052 Utility yaz-iconv is now installed by default along with the man page
2055 Extend configure check for OpenSSL to use pkg-config where available (such
2058 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2059 server to specify uid/gid/mask for socket using the format
2060 unix:[user=uid,][group=gid,][umask=mask,]file=path
2061 If file= is omitted the existing format is assumed, e.g.
2063 in which case the mask is 0666 (rw for everybody).
2065 Major restructure of YAZ source. All source in libyaz is in src directory.
2066 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2067 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2069 Added man page for utility yaz-marcdump (used to be called marcdump).
2070 yaz-marcdump is installed by 'make install'.
2072 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2073 of incoming package failed.
2075 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2077 Change prototype of odr_perror: add const to message string.
2079 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2081 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2082 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2083 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2084 DNS lookup. There should not be any compatibility problems with this
2085 assuming that blocking=1 or 0 is used.
2087 Fix bad reference in UNIX comstack in function cs_addrstr.
2089 Fix for compilation on AIX.
2091 The generic front-end server (server/seshigh.c) now supports returning
2092 Init diagnostics to the client in User-information-field, in
2093 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2096 --- 2.0.4 2003/09/04
2098 Allow any CQL relation (not just all,any,exact,scr).
2100 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2101 that features the same UI.
2103 Implemented command update0 in YAZ client which is equivalent to
2104 update but uses old of Ext Update ASN.1.
2106 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2107 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2108 Previously no OID was used for this info.
2110 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2111 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2112 returns 'malformed search term' otherwise.
2114 SortResponse member resultCount now set to NULL in sort handler of
2117 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2120 Add three new utility functions for translating OIDs between various
2121 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2122 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2123 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2124 char *oid_to_dotstring(const int *oid, char *oidbuf);
2125 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2127 Reverted modifications for ES Update definition for z_IU0Update
2128 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2129 is back to YAZ 2.0.2.
2131 String value attributes for CCL parser.
2133 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2134 which their FirstSearch server returns in Init responses, sometimes
2135 carrying useful diagnostic information when Init fails. This has the
2136 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2137 "z39.50/oclcui.asn", where its definition is somewhat different from
2138 what OCLC document on their web-site, as required to interoperate with
2141 Support for anonymous authentication in yaz-client. Use the command
2144 * Fix the OID of the Index Data-local "admin" Extended Service from
2145 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2146 the 1000, which indicates a locally-defined OID, was a mistake.
2148 --- 2.0.3 2003/06/20
2150 Fix CCL directive @case handling so that it affects string match for
2151 both CCL keywords and qualifiers.
2153 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2154 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2155 Decoder has been updated with ASN.1 changes as listed in
2156 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2157 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2158 z_IUUpdate, remains unchanged.
2160 ZOOM_record_get may now return a record in a specific character set.
2161 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2162 "from" is the character set of record as returned by target. "to" is
2163 the character set to be returned. If omitted, "to" is UTF-8.
2165 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2167 New ODR utility, odr_getelement, which returns name of element for
2168 which encoding/decoding failed.
2170 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2171 in cases where a required element was omitted.
2173 Bug fix: some MARC8 sequences were not converted.
2175 New ZOOM option "step" which specifies number of records to be
2176 retrieved in one chunk. Used in conjunction with "start" and "count".
2178 SRW support for yaz-client. Use scheme http: to use it, e.g.
2181 yaz-client no longer does (un)intelligent character set conversions
2182 by default. Can be enabled with charset and marc_charset commands.
2184 xmalloc trace fix for 64-bit systems such as DEC alpha.
2186 Solaris 2.6 compile fix.
2188 New function, cql_strerror() translates SRW error codes, as returned
2189 by cql_transform_error(), into human-readable English strings. Used
2190 in yaz-client diagnostics when appropriate.
2192 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2193 converts it into a type-1 query which is sent to the server. This
2194 makes CQL available for use with all Z-servers, as opposed to the tiny
2195 minority that can handle CQL queries themselves.
2197 --- 2.0.2 2003/04/28
2199 New Debian package layout similar to the Redhat Package layout.
2201 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2202 and search result respectively.
2204 --- 2.0.1 2003/04/25
2206 Redhat package is now several packages: libyaz (runtime libraries),
2207 libyaz-devel (development and documentation, and yaz (utility programs).
2208 Package spec file by Morten Bogeskov.
2210 New member 'schema' in struct bend_fetch_rr which the name of requested
2211 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2212 handler MAY set this to reflect the schema of the returned record.
2214 New member 'display_term' in struct scan_entry. GFS now sets member entries
2215 and allocates scan entries to be filled by user scan handler. In previous
2216 version, entries member was allocated by the scan handler. That still works,
2217 but the GFS will ignore member display_term - assuming it was NOT set by
2218 the handler. The fact that the GFS now allocates the entries both allows
2219 for new members and makes a scan handler easier to write.
2221 Fix CQL lex buffer overflow.
2223 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2224 SRU default recordPacking is string.
2226 SRU protocol support for frontend server.
2228 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2230 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2232 Added scan for the ZOOM shell (zoomsh).
2236 * String Identifers for Schemas (Amendment 5).
2237 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2238 Old definition for schema
2239 Odr_oid *schema; /* OPT */
2244 Z_InternationalString *uri;
2245 #define Z_Schema_oid 1
2246 #define Z_Schema_uri 2
2249 * resultCount parameter to Sort Response (Amendment 1).
2250 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2252 Support for SRW 1.0 over HTTP. This is an optional feature and
2253 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2256 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2257 on the same port. SRW SearchRetrieveRequests are mapped
2258 to bend_init,bend_search,bend_fetch,bend_close.
2260 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2262 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2263 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2265 ZOOM connections are SRW based if schem http is used for hostname
2266 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2267 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2269 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2270 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2271 distance=n, order=true/false, relation=le, prox unit=word. If
2272 n is omitted, distance 1 is used.
2274 Fixed problem with C compiler include path in wrong order.
2276 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2277 on Solaris. Patch from Ko van der Sloot.
2279 New MARC decode API. All new functions operate on a yaz_marc_t
2280 handle. The most important new functions are: yaz_marc_create,
2281 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2282 decode and destroy respectively. Decoder can produce formats
2283 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2284 include/yaz/marcdisp.h.
2286 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2287 to UTF-8, UCS-32, wchar_t or Latin-1.
2289 * Prototypes for yaz_iconv_-functions moved to separate header
2290 include/yaz/yaz-iconv.h.
2292 Make a few private functions 'static' in unix.c. This prevents
2293 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2295 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2296 are set when Init Response is received.
2298 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2299 but returns diagnostic set as well.
2301 New function yaz_strerror which is a portable wrapper for
2302 strerror/strerror_r/GetLastMessage.
2304 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2305 is returned for MARC. If type is "oai", then OAI MARC is returned.
2307 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2310 --- 1.9.2 2002/11/26
2312 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2314 Fix bad race conditions on SIGTERM and terminate gracefully in
2317 Move retrieval (data1) module to Zebra since nobody seems to be
2320 Add GRS-1 render for ZOOM using same format as yaz-client.
2322 --- 1.9.1 2002/10/05
2324 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2326 Fix broken ESpec handling in data1 module.
2328 SGML reader parses comments and makes them part of the data1 tree.
2330 Added several type casts so that YAZ compiles as C++ code.
2332 ZOOM didn't handle PDU encoding failures properly.
2334 Added more Bib-1 diagnostics (approved extensions).
2336 GNU configure: better check for iconv.
2338 More portable use of accept, getpeername. Check for socklen_t. Use
2339 int/size_t if socklen_t is not defined.
2343 PQF parser rejects bad queries - including those with extra
2344 characters in them. PQF parser used to silently ignore that.
2345 Cleaner API for PQF added, which allows you to get detailed
2346 error information for bad queries (see yaz/pquery.h).
2348 Fixed bug in ZOOM_record_get for type "database".
2350 Implemented mini iconv library supporting conversions between
2351 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2353 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2355 --- 1.8.9 2002/08/20
2357 Fixed ZOOM C record cache so that preferredRecordSyntax and
2358 elementSetName is used to check for already fetched records.
2360 --- 1.8.8 2002/08/02
2362 Added three members in bend_initrequest structure to facilitate
2363 character set negotiation.
2365 Fixed a bug in frontend server that could cause indefinite
2366 loops under rare conditions.
2368 Revised character set utilities (charneg.h) so that encoding
2369 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2371 For PQF, directive @term <type> sets term type for Scan/Search.
2372 Here <type> is general, string, numeric, null. The term type
2373 is inherited - just like @attr.
2375 New call odr_set_charset that sets character set conversion for
2376 international-strings on a ODR stream. Prototype is:
2377 int odr_set_charset(ODR o, const char *to, const char *from);
2378 The InternationalString is still represented as C string in YAZ
2379 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2380 won't). On the protocol level, you can use any encoding.
2382 Support for UNIX sockets in ZOOM.
2384 Solaris recv sometimes returns errno == ENOENT. It is treated as
2385 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2387 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2388 both client and server. Code by Morten Bogeskov.
2390 --- 1.8.7 2002/05/22
2392 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2393 that they can be used directly from Visual Basic. You must recompile
2394 your windows APP if you're using ZOOM.
2396 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2397 Commands "lang" and "charset" sets language and character set respectively.
2398 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2399 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2401 Attributes from multiple CCL fields may be OR'ed rather than merged
2402 using directive "@field or". Fields are still merged by default -
2403 equivalent to "@field merge".
2405 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2408 Fixed bug in zget for parameter ExtendedServicesResponse.
2412 --- 1.8.6 2002/03/25
2414 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2416 Client displays USR.1:SearchResult-1 (hits per term).
2418 Additional Search Info for search in Generic Frontend Server.
2420 Fixed CCL parsing of "field=s".
2422 WIN32 installer - using the excellent NSIS software from nullsoft.
2424 Fixed CCL parsing of "field = - <number>".
2426 Added function yaz_marc_decode that decodes MARC for line mode
2427 display or XML (similar to that used by JZKit).
2429 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2430 Z39.50. But ISO/ILL was, however.
2432 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2433 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2435 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2436 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2438 --- 1.8.5 2002/02/03
2440 New YAZ client features: Command completion and new commands:
2441 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2442 Code provided by Jacob Poulsen.
2444 New call oid_trav, that visits all registered OIDs via callback.
2446 Function ZOOM_record_get now returns const char pointer rather than
2447 void pointer. It saves a lot of type casts.
2449 For YAZ client, command "auth" now allows you to set authentication
2450 in IdPass style. It is enabled when three tokens are given - order
2451 is user, group and password.
2453 Fix memory leaks in MARC record handling for ZOOM.
2455 New option for YAZ client, -k <kilobytes> that sets
2456 maximum record size. Similar to -k option for generic frontend
2457 server and yaz-ztest.
2459 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2461 Prefix query parser reports "fail" when bad attribute set is given.
2463 Fix in MARC decoder. Proximity logging. Fix for attribute set
2464 in scan handler for server. Patches by Shigeru Ishida.
2466 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2469 Configure option --with-openssl=<dir> now works when a directory is
2470 specified. Patch provided by Morten Bogeskov.
2472 New option for YAZ client, -u <auth>, that sets authentication.
2474 ZOOM fix: error information was sometimes "missing", since error
2475 was cleared/reset too when it shouldn't.
2477 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2479 --- 1.8.4 2002/01/04
2481 Scan for ZOOM API. New object ZOOM_scanset. New functions
2482 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2483 ZOOM_scanset_destroy.
2485 New ZOOM function, ZOOM_connection_last_event, that returns type
2486 of last event (such as "receive data", "send data", "apdu received",
2489 New ZOOM option, schema, that specifies schema for retrieval.
2491 New CCL feature. Qualifiers can be aliases for one or more
2492 other qualifiers (if more than one is given, OR is used).
2494 ZOOM uses named result sets if target supports it.
2496 Two new YAZ client commands: . (dot, which sources a script of YAZ
2497 client commands), and ! (to execute shell command.). Implemented
2500 Working on Debian packages.
2502 --- 1.8.3 2001/11/19
2504 YAZ client enables named result sets only if target supports it.
2506 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2508 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2509 with key="host" to get same result.
2511 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2512 Function Z3950_resultset_record(s) returns references to records
2513 "owned" by resultset. To become owner use Z3950_record_clone.
2515 Function z_ext_record handles Extended Services. Thanks to
2518 --- 1.8.2 2001/11/12
2520 CCL Parser fix: ignore token comma when dealing with and-lists.
2522 Documentation updates for COMSTACK.
2524 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2525 Changed prototype Z3950_records. For some functions, int parameters
2526 were changed to size_t.
2528 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2531 New MARC decode/display function, marc_display_exl, which properly rejects
2532 non-ISO2709 records. YAZ client uses it.
2534 --- 1.8.1 2001/10/29
2536 Fix bug: local attribute set wasn't set correctly in PQF strings.
2540 * Old Z39.50 codecs no longer supported.
2542 Added ZOOM C binding. See http://zoom.z3950.org/
2544 Renamed states for COMSTACKs to avoid confusion with events.
2546 Implemented cs_look and proper cs_rcvconnect.
2548 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2550 Configure detects POSIX threads on OpenBSD.
2552 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2553 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2555 When error is returned from present handler, non-surrogate diagnostic
2556 is returned in present response (and fetch handler is no longer called).
2558 * Minor adjustments to pquery parser (PQF). Token characters may be
2559 escaped by using backslash (C-style).
2561 PQF parser allows string attribute values to be specified. For @attr,
2562 non-numeric characters after the equal-sign are treated as strings
2563 (e.g. @attr 9=title).
2565 CCL trunction character may be defined (@truncation in file)
2567 * function zget_ExtendedServicesRequest sets waitAction to
2568 waitIfPossible (was wait).
2570 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2573 CCL operator names may be set in field definition files (CCL_bibset).
2574 See ccl/bib1 for an example.
2576 Fixes in ASN.1 compiler for C++ compatibility.
2578 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2579 and "op_or" to avoid conflict with C++.
2581 Fixed problem with GNU readline detection on Redhat 7.0.
2583 Added step-size for Scan backend handler.
2585 Fixed bug that made the frontend server crash when no attribute
2586 set was specified for scan.
2588 Front-end server automatically switches to original working directory
2589 when installed as an NT service. Previously -w had to be specified to
2592 Added extended attributes for retrieval module (data1), so that data1
2593 records carry d1_readXML/SGML attributes. d1_read also supports
2594 null-data rules ( <tag/>)
2596 On UNIX when POSIX threads are available, a separate library libyazthread
2597 is created. Programmers should link with that library and the yaz library
2598 when using threads. The reason for the split was that some applications
2599 on Linux, such as Apache, doesn't work well when using shared objects that
2602 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2603 (or any frontend server) in SSL mode by specifying ssl: followed by
2604 address. Only tested on UNIX.
2606 Added feature for CCL module. Virtual structure s=al or s=ol generates
2607 and-list and or-list respectively instead of phrase search.
2611 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2612 log_mask_str. This was done to avoid name conflicts with other libraries
2613 (such as other PHP extensions).
2615 Added raw OID member for preferred record syntax (request_format_raw)
2616 and returned record syntax (output_format_raw) for backend fetch method.
2618 Config file yaz-config now accepts options so that it returns specific
2619 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2621 Shared library support for UNIX using GNU libtool.
2623 * Modified backend interface. Request/Response struct's replaced by
2624 one read/write C struct. For example bend_fetchrequest and
2625 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2626 Every handler - even search has to be registered in bend_init
2627 handler. This means that the YAZ library no longer refers to
2628 external functions and it makes it possible to make the whole
2629 thing a single DLL/SO.
2631 Added Segment handler for backend server.
2633 Added Zmbol/Zebra administrative functions to YAZ client.
2635 Threaded frontend server on UNIX (when POSIX Threads are available).
2636 Starting the server with option -T enables multi-threading.
2640 Added configure option --enable-comp/disable-comp to control use
2641 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2642 located in sub directory asn.
2644 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2645 in ${exec_prefix}/bin along with the other programs yaz-client and
2648 GNU automake used to maintain makefiles.
2650 Added several OID's.
2652 Changed retrieval module so that we can load records with no abstract
2653 syntax defined. Tagpaths in these records are fully composed of string
2656 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2660 On UNIX, the generated makefile now supports a proper 'make install'.
2661 The prefix can be set via GNU configure to set the install location
2662 (default is /usr/local).
2664 * YAZ programs client and ztest were renamed to yaz-client and
2665 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2666 locations, such as /usr/bin,/usr/local/bin,etc.
2668 * YAZ Header files were moved from include to include/yaz. YAZ Header
2669 files are referred to as include <yaz/log.h> rather than <log.h>.
2670 The YAZ include path (-I ..) is therefore the same as before. Programmers
2671 should update their #include statements or use -Ipath/include/yaz
2672 instead. The main motivation for doing this change is that YAZ header files
2673 can be installed in "standard" locations /usr/include,/usr/local/include
2674 without introducing conflicts, since ALL YAZ header files are stored
2675 in subdirectory yaz (under /usr/include for example).
2677 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2678 rather than project/workspace files. We switched because project files
2679 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2682 Changed name of logging function, logf, to yaz_log, to prevent name
2683 clash with some math-log functions. The YAZ header log.h defines logf
2684 to yaz_log (#define) so there should be no incompatibilities by this
2687 Added bend_start/bend_stop handlers for server. These handler are
2688 called on start/stop of server. For windows they are called whenever
2689 a service is started/stopped.
2691 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2692 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2693 in util/yc.tcl. The auto-generated C code structures are, in a few
2694 cases, incompatible with the old decoders. There are differences in the
2695 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2696 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2697 The preprocessor variable ASN_COMPILED is defined when the compiled
2698 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2699 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2700 wish to use the old encoders/decoders you can specify --disable-yc
2703 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2704 version so that it supports both new - and old version of DB Update
2706 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2707 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2708 change. The name parameter can be set to 0 in which no name is specified
2709 for the construction. The macros odr_implicit and odr_explicit sets name
2710 parameter to zero for the construction involved. New macros
2711 odr_implicit_tag and odr_explicit_tag are similar to the others,
2712 except that a name parameter is added. For programmers' that don't use
2713 ODR they probably only need to change the call to z_APDU and z_External.
2715 Added access control facility by interfacing the TCP wrapper library.
2716 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2717 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2718 name of the daemon and enables the access control as specified in
2719 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2721 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2722 den Dool <H.M.vdnDool@kub.nl>.
2724 Added reference ID parameter to most functions in server API - refer
2725 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2727 Changed name of ccl library to libccl.a (was ccl.a).
2729 Fixed bug in decoder for Explain (Category TargetInfo).
2731 Added support for GNU readline in client. Thanks to Jacob Poulsen
2732 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2734 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2735 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2736 IMPLEMENTATION! This change was made to the development version before
2737 the ZIG decided to retract the amendment. If any users MUST be
2738 compatible with the original Update definition, PLEASE CONTACT US, and
2739 we will include a separate definition corresponding to the old Update
2740 ES. Note that because of the change to the ASN.1 of the
2741 TaskPackageRecordStructure we cannot define a single structure that
2742 will support both versions.
2744 * Added const modifier to buffer parameter for some ODR/BER encoding
2745 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2746 completeWAIS, odr_dumpBER.
2748 Fixed bug in client.c which caused a crash when a scanResponse didn't
2749 contain positionOfTerm.
2751 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2752 * will cause an error in a client if a non-YAZ target sends both a
2753 * list of Scan entries and non-surrogate diagnostics.
2755 Retrieval module enhancements. Tag sets may be typed in the reference
2756 to it. From the .abs-file the "tagset" directive takes a third optional
2757 integer type for the tag set referenced. From a .tag-file the "include"
2758 directive takes a third optional type as well. The old "type" directive
2759 in the tag set itself is still recognized but acts as the default type
2762 Backend interface change. Individual Scan terms returned from bend_scan
2763 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2764 in include/backend.h.
2766 Retrieval module enhancements. Multiple tag sets and attribute sets may
2767 be specified in abstract syntax specs. Revised the error/warning for
2768 logging messages reported by the retrieval module when reading the
2771 Object Identifier system (oid_..) changed. The API is backwards
2772 compatible but the oid-routines now allocates new OID's when needed.
2773 Raw OID's may be specified in oid_getvalbyname.
2775 YAZ now uses GNU configure to generate Makefile(s).
2777 * Minor changes in some of the member names of DeleteResultSetRequest and
2778 DeleteResultSetResponse. See include/proto.h.
2780 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2781 and added member 'languages' in TargetInfo (which was missing).
2783 Changed the way attribute sets are handled in the retrieval
2784 module. These are now cached, just like the abstract syntaxes
2787 Changed YAZ so that it links with compiled ASN.1.
2789 Added Explain-schema definitions and mapping routines. The following
2790 Explain categories have been implemented: AttributeDetails,
2791 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2793 Fixed minor bug in Windows version of Server Library.
2795 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2797 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2799 Added EXTERNAL: UNIverse Resource Report (non-standard).
2801 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2802 ENUMERATED and SET OF.
2804 * Added 'const' to some of the char pointer arguments for the
2805 functions, data1_read_node, data1_getelementbytagname,
2806 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2809 Fixed bug in data1_insert_taggeddata - the last_child member of
2810 parent wasn't initialised.
2812 * Changed data1_read_record and data1_read_node so that the supplied
2813 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2814 doesn't refer to any parts of the "SGML"-buffer.
2816 Fixed bug in server library (Windows version of statserv_remove).
2818 * Changed code so that it compiles as C++. The type definition
2819 of Odr_fun which is a member of Odr_arm was changed. The result is,
2820 that an explicit typecast is needed for the fun pointer when
2821 using Odr_arm - as in:
2822 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2824 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2826 Implemented the new structured date and time definition as approved
2827 by the ZIG. Added schemaId element to the specificTag in Espec-1
2828 (also approved at the last ZIG). Thanks to RVDM.
2830 Added some Object identifiers (RVDM).
2832 Changed the Update Extended Service (RVDM).
2834 Added command "refid" to client which specifies referenceId for
2835 the following requests.
2837 Implemented extended service handling for server. See ztest.c
2838 for an example as well as backend.h. New handlers are registerd
2839 in the Init handler.
2841 * Changed interface for sort in server.
2843 Added new members to statserv_options_block. It allows a server
2844 to read options from another source than just the command line. Thanks
2845 to Charles Woodfield.
2847 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2848 renamed to zboolean. Some C++ compilers complained about the name.
2850 Minor changes to gils.abs. Added index 's' (sort) on title
2851 and date/time-last-modified.
2853 --- 1.4pl2 1998/1/30
2855 Fixed bug in server library regarding inetd mode (-i). This bug
2856 was introduced by release 1.4.
2858 --- 1.4pl1 1998/1/29
2860 Added sort facility in client and backend server interface.
2862 Fixed problem with dependencies in Makefile(s).
2864 Fixed bugs for encoders/decoders of extended services and
2867 Implemented sub-tree feature for schemas. Sub-trees are
2868 referenced in *.abs-files. See explain.abs for an example
2869 of the use of this feature.
2871 Modified bib1.att; local attributes for ANY didn't include
2872 ANY itself (only affects use of the retrieval module).
2874 Fixed bug in plain SGML reader in function data1_read_node:
2875 tags with prefix "var" was incorrectly interpreted as variants.
2877 Added feature "sub-schemas" to enable references to - and definitions
2878 of - group of elements.
2880 * Removed member parent from type data1_element (in data1.h).
2882 Implemented function odr_nullval() that returns the value of
2885 * Removed member num_children from data1_node (in data1.h).
2887 Made NT service interface part of the server library. The
2888 function statserv_main uses the NT service when required and
2889 calls the statserv_start / statserv_close routines.
2891 Routine zget_SearchRequest and zget_PresentRequest fills
2892 resultSetName/Id member with "default" instead of "Default".
2894 Fixed memory leak in server. Request queue member wasn't freed.
2896 Fixed nmem_exit so that memory is freed.
2900 Revised the CCL parser utility to be thread safe.
2902 Added function, oid_ent_to_oid, to replace the function
2903 oid_getoidbyent, which is not thread safe.
2905 * Added nmem_init and nmem_exit to initialize and release
2906 NMEM resources. Function nmem_init should be called once in the
2907 initial thread before NMEM/ODR is used. statserv.c and client.c
2908 have been changed accordingly. The change was necessary to make
2909 NMEM thread safe. The NMEM memory pool is shared amongst threads
2910 in a process. Unix-based applications will still work fine without
2913 Added NT Services interface for the the Z39.50 (statserv) Server.
2914 Refer to the ztest.c source on the usage.
2916 Windows 95/NT port using MSVC5.0. Project files are included in the
2919 * Defined new 'global' handle for the retrieval (data1) system. The
2920 new handled, data1_handle, describes the state of the data1 system.
2921 This handle is passed as first argument to virtually all
2922 data1 related routines. The functions data1_create and data1_destroy
2923 creates and destroys a data1 handle respectively.
2925 Added ODR encode stream member to all backend request structures
2926 init, search, scan etc. This stream should be used to allocate all
2927 memory used for the response when thread safe operation is needed.
2929 Changed the comstack utility, cs_addstr, to be thread safe. The
2930 returned hostname string returned by the function is now part the
2933 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2934 function. The cs_straddr takes a COMSTACK handle as argument, so this
2935 function must be used after cs_create and before bind/connect.
2936 This function is thread safe.
2938 Moved test server to 'ztest' directory - generic server code still
2939 in 'server' directory.
2941 Made prefix query (pquery.c) utility thread safe.
2943 Added new function modifier YAZ_EXPORT to 'export' public DLL
2944 functions when using windows (see include/yconfig.h).
2946 Added definitions to the OID database (util/oid.c) (RVDM).
2948 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2950 Added call to ccl_rpn_delete in client program.
2952 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2953 release of RPN structure.
2955 Added support for C++, headers uses extern "C" for public definitions.
2956 With input from RVDM.
2958 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2959 Thanks to Ronald van der Meer (RVDM).
2961 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2963 Added support for private extensions to the OID database
2964 (oid_setprivateoids()). Thanks to RVDM.
2966 Added optional, physical ANY (key replication)
2968 Fixed null-reference problem in GRS-1 output filter.
2970 Proximity operator added to Prefix Query Format (PQF).
2972 In test client command "base" accepts multiple databases.
2974 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2978 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2980 Smallish bug-fixes in the new encoders/decoders (explain).
2982 Bug fixed in DeleteRequest.
2984 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2986 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2988 Added SOIF syntax (using private OID for now) to retrieval module and client.
2990 Added Update extended service.
2992 Added SearchResult-1 additional info structure.
2994 Added optional CCL (ISO8777) interpreter as separate module. Available
2997 --- 1.2 1996/6/10 (1st anniversary release)
2999 Added Summary record syntax. Lightly tested.
3001 Added OPAC record syntax. Untested.
3003 Added ResourceReport service encoders/decoders. Untested.
3005 Fixed bug in z_Unit - wrong tagging on unitSystem.
3007 Fixed bug in the DiagRecs decoder.
3009 Added options for max PDU size and session timeout to frontend-server.
3011 Added documentation of query-language parsers and other supporting utilities.
3013 [frontend-server] Added Attribute set to the bend_scanrequest API.
3015 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3016 surrogate diagnostics were generated.
3018 [retrieval] Allow multiple local values for attribute.
3020 [retrieval] Allow multiple attributes per element in .abs files. index type.
3022 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3024 --- 1.1pl2 1996/4/10
3026 Minor changes, mostly specific to Zebra's requirements (retrieval)
3030 Repaired bug in frontend server when running multiple listening
3031 endpoints in dynamic mode.
3033 z_External() now won't break if a known, ASN.1 value comes encapsulated
3034 in an octet-string. The value will pass through unmodified in an Odr_oct.
3036 Added a bit of code to the demo client to decode & display
3037 ASN.1-structured records represented in the octet-aligned branch of
3038 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3040 Added z_ext_getentbyref() to the ASN module. Doc updated.
3042 * Completed the SCAN definition in the ASN module. This may break SCAN
3043 code based on older YAZ-versions at compile-time. The fix is easy -
3046 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3047 under the SCAN definition. Remember to initialize this, server-people.
3049 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3050 that this does not extend to ODR and ASN.
3052 Comstack allows insertion of established socket (primarily for
3053 inetd-operation of servers). Doc updated.
3055 Front-end server can now start from the inetd in TCP mode. Doc
3058 --- 1.0pl4 1996/1/24
3062 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3063 the rank and record number.
3065 Adjustments to the frontend server.
3067 Fixed diagnostic BER dumper. It ignored the file argument.
3071 Various changes to retrieval module.
3073 Changed the union discriminators of the protocol files from enums to
3074 ints paired with #defines.
3076 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3079 *Changed operator in the RPN structure to 'roperator', again to avoid a
3082 Fixed problems in Explain decoders/encoders.
3084 --- 1.0pl2 1995/12/6
3086 Memory bug in log module fixed.
3088 --- 1.0pl1 1995/12/5
3090 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3092 Bug in Explain DatabaseInfo module fixed.
3094 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3098 The shift to v1.0 signals that we now consider the *core* functionality
3099 of YAZ reasonably stable (the core being more or less equivalent to
3100 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3101 tested (Explain not at all - though that will happen soonish).
3103 Minor changes to code to support Windows port.
3105 Various minor changes after we're getting to use GRS-1 & co. more.
3107 Added Espec-1 format.
3109 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3110 of the protocol and it cannot be selected when encoding (maps into 'string'
3111 when decoding). Needed to talk to some servers.
3113 Demo client can request simple element set names.
3115 Added Diagnostic Format encoders/decoders.
3117 Added simple Close handling to frontend server (no hooks for resource
3118 reporting yet), and demonstration client.
3120 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3122 --- 1.0b3 1995/08/24
3124 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3125 handled incorrectly when records were requested in the searchResponse. This
3126 will only affect you if you use the frontend-server.
3128 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3129 Test-client will ask for and print GRS1. Ztest will return dummy records
3132 Added Explain encoders/decoders to the service-level API. Untested.
3134 Added Extended Services: Item Order encoders and decoders to the Service-
3135 level API. Untested. We could use a recent copy of the pertinent bits
3136 of the ILL protocol to add those bits.
3138 Added diagnostic format 1 encoders/decoders to the service-level API.
3141 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3142 odr_cons.c, which causes a more correct output.
3144 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3145 was always set to 0 when no records were requested in the searchRequest.
3147 * Added better external-handling. This shouldn't harm old code that
3148 *encodes* externals. It can break code that looks for a
3149 'single-ASN1-type' representation, since those types that are known
3150 are now decoded immediately. Look at the SUTRS sample code in
3151 seshigh.c and client.c. Documentation updated.
3153 Handling of structured records in bend_fetchresponse. Length -1 marks
3154 structured record, type is deduced from format field.
3156 --- 1.0b2 1995/06/27
3157 Fairly quick maintenance release to add SUTRS support.
3159 Fixed handling of SUTRS records in the demonstration client.
3161 * Added format field to the bend_fetchrequest and bend_fetchresponce
3162 structures of the backend API (frontend server). When the record is
3163 returned, the value of the format field is mapped to an OID. The
3164 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3165 of the record. The special value VAL_NONE in the bend_request means
3166 that no specific format was requested by the client. Documentation
3167 updated accordingly. Test server (ztest) will return a fixed dummy
3168 SUTRS record if your client requests SUTRS.
3170 Documentation updated accordingly.
3172 You can now set external libraries and RANLIB support in the top-level
3176 First public release.
