1 Support for log levels on module logging. Call with MODULE_ID or'ed with log level.
2 Only log if log level is set. Still log if no log level is set.
6 New function for daemon utility, yaz_daemon_stop .
8 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
12 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
13 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
17 YAZ daemon utility relays SIGUSR1 to child process.
19 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
20 would result in en empty database list - which in turn would result in
21 encoding failure for search.
23 Fix reading beyond string in yaz_sort_spec.
27 Add two new SRU diagnostics:
28 236: Access to specified database denied
29 1015: Init/AC: Maximum number of simultaneous sessions for Userid
31 Document the very useful ZOOM-C option "apdulog".
33 CQL to RPN: term may be passed through verbatim. This is enabled with
34 truncation.cql . The assumption being that the term is already CQL.
38 record_conv: leader spec may be given for marc element.
39 The leader spec is given as attribute leaderspec for element marc.
40 For example to convert a MARC21 record from MARC-8 to UTF-8:
41 <marc inputformat="marc" outputformat="marc"
42 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
44 record_conv: allow user-XSLT params. For example:
45 <xslt stylesheet="MARC21slim2DC.xsl">
46 <param name="myparameter" value="myvalue"/>
47 <param name="otherparameter" value="othervalue"/>
50 record_conv: fix error handling for missing marc charsets.
52 CQL: fix extra terms in wrong order.
56 record_conv: modify new API for conversion types. The conversion types
57 may be passed in new functions yaz_record_conv_configure_t and
58 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
60 Avoid mixed statement/variable declare; fixes compilation with Visual
65 Add non-standard SRU diagnostic: 235: "Database does not exist".
66 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
67 Update SRU to Bib-1 diagnostic maps accordingly.
69 CCL: add two new diagnostics for unsupported masking. The new
70 diagnostics are: "Embedded truncation not supported" and
71 "Single charcacter mask not supported".
75 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
79 Build YAZ for Ubuntu Oneiric.
81 CCL: allow parantheses for proximity operands. For example CCL query
82 (a) % (b) is now allowed.
84 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
85 marked dead, rather then being destroyed. If not, the session memory is
86 being free'd before the search/scan handler is finished. Also destroy
87 'request' memory in request_release rather than in various places,
88 which resulted in leaks from time to time.
92 cql_sortby_to_sortkeys: honor sort prefix.
94 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
95 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
96 The rpn2cql family of functions now always returns quoted CQL terms.
98 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
100 --- 4.2.23 2011/12/15
102 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
103 sequence is treated as one. For example, &&a=b&&&c& is identical to
106 --- 4.2.22 2011/12/05
108 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
109 APDUs for a connection to a WRBUF.
111 --- 4.2.21 2011/11/23
113 Fix cql_sortby_to_sortkeys. Completely broken before.
115 Make CCL's @truncation work again.
117 --- 4.2.20 2011/11/09
119 New ZOOM connection setting: tproxy. It's like proxy, but does not
120 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
121 to set resolved address + port for a connection outside ZOOM itself.
123 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
125 --- 4.2.19 2011/11/07
127 Fix uninitialized variable in Solr spell support (could cause SEGV
128 for SRU response decoding).
130 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
131 back-end's addinfo through into the ZOOM response addinfo.
133 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
134 they are separated by a colon and a space rather than simply
137 --- 4.2.18 2011/10/28
139 Add support for Solr spell-checking/suggestions through ZOOM.
140 If a Solr target has been configured correctly for spelling-checking
141 and suggestions, these will now be returned on the ResultSet option
142 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
144 --- 4.2.17 2011/09/28
146 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
147 with a flag whether to substitute escape sequences or not.
149 --- 4.2.16 2011/09/22
151 Fix nmem_strsplit_escape to substitute escape char properly.
153 New option for zoomsh -e , which makes it abort on first error and
154 return process exit code to indicate success/failure.
156 YAZ options utility supports special option -- which makes all it treat
157 all following arguments as non-options.
159 --- 4.2.15 2011/09/16
161 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
162 searched if absolute filename is given.
164 Fix conv_xslt() error-reporting when stylesheet is not found.
165 (The value of fullpath is meaningless in this situation.)
167 --- 4.2.14 2011/09/07
169 Fix problem in CQL sort node creation: un-initialized memory.
171 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
172 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
173 CQL sortby depending on whether Type-1 or CQL is actually sent to the
176 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
177 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
179 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
180 will make it possible to use both single-character mask (#) and wildcard (?)
181 in CCL . Throw diagnostic for left truncation because that is not supported
184 --- 4.2.13 2011/09/01
186 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
187 cases using escapes (\-sequences) and masking.
189 PQF parse fix: A trailing backslash followed by end-of-string (\0)
190 would result in a read one byte beyond string.
192 rpn2ccl may use Z39.50 masking for terms (t=z).
194 ICU check fix. Don't include library -lCrun on Solaris, unless present.
196 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
197 not --cppflags (which seeems like an error in icu-config).
199 --- 4.2.12 2011/08/27 RPM package only
201 cql2ccl: fix conversion of terms: operator characters were not
204 --- 4.2.11 2011/08/25 RPM package only
206 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
207 CCL parser will map both # and ? to their regular expression
208 quivalents (. and .*).
210 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
211 of reserved CQL characters.
213 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
214 is, so that they are passed through.
216 --- 4.2.10 2011/08/24
218 ZOOM SRU mode: more aggressive re-connect.
220 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
221 made available as a utility function, declared in <yaz/logrpn.h>
223 rpn2cql_structure() supports proximity nodes (except that the Type-1
224 proximity node's "exclusion" binary is ignored, as there is no way to
225 express that in CQL). Fixes bug #4564.
229 Fix SEGV that could occur if set command of zoomsh was given without
230 value (2nd argument).
232 Fix SEGV that could occur if unsupported transport was given for
233 COMSTACK - say https (when SSL was unavailable).
235 Build yaz-url on Windows too.
239 New utility to get web content. Header is url.h. A command line tool
240 yaz-url is part of the distribution and packages.
242 Fixes for SSL COMSTACK (when gnutls is in use).
244 New functions yaz_base64{encode,decode}. Header is base64.h.
248 ZOOM C includes HTTP response buffer as additional info if it fails
249 to decode the SRU response.
251 Make wrbuf_json_puts available.
255 zoom: throw diagnostic for invalid value for option "sru". Before a
256 bad SRU request was sent.
258 Adding new utility wrbuf_vp_puts.
260 Add cclxmlconfig.obj to win/makefile. It was missing completely.
264 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
265 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
266 redirect was used at the same time.
268 MARC line mode decoding: be less picky about length given - first
269 5 digits of header that is.
271 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
273 Changes to decoding of SRU records: a record with recordPacking=xml is
274 modified with a new root element <yaz_record> if the recordData contains
275 multiple children elements. This is to make the record XML parseable
278 RPN to SOLR conversion: encode special characters.
280 Generic Frontend Server: fix uinitialized member, stepSize.
284 Fix a bug in SRU decoding of records.. The database records stored
285 had un-initialized memory, but it would only be seen with yaz_record_render
286 and type_spec="ext" .
288 Fix a bug in ccl_qual_dup introduced in 4.2.3.
292 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
296 Add new utilities to convert from CQL to CCL . These utilities have
297 prefix cql_to_ccl defined in cql.h.
299 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
300 lead to memory heap corruptions when ICU utilities were in use.
304 Make compilation work without Libxml2.
306 yaz-client: remove redundant blanks in display of searchResult-1 term
311 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
312 resulting CQL node (tree) in a new node CQL_NODE_SORT.
314 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
315 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
316 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
317 Note that the CQL sortby spec is only converted when the GFS is already
318 converting from CQL to RPN (cql2rpn element).
320 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
321 specify whether to collapse delimitors or not. The existing nmem_strsplit
322 do collapse (collapse parameter = 1).
324 Windows installer: For NSIS, set InstallDir depending on x86/x64.
326 Rename internal func yaz_use_attribute_create. While non-static, this
327 function is not declared in a public header.
331 Add -lCrun when linking with ICU on Solaris.
333 More quicks character set conversions for OPAC records.
337 fix problem with record_render: records were converted (character set
338 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
342 SRU: add methods for handling DADS SRU-proxy facets.
344 Separate OPAC record character set for ZOOM_record. yaz_record_render
345 allows a character set given as charset=from/opacfrom,to where 'from' is
346 the character set of a bibliographic record, 'opacfrom' is character set
347 of OPAC record and 'to' is the target character set.
351 yaz-client: show may XML format records. Command show followed by 'format'
352 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
355 src/stemmer.c: Avoid using unnamed union. It is not supported by some
358 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
361 Update yaz.spec to operate on both SLES11 / Centos 5.5.
363 RPM: Release includes 'indexdata' name. Use indexdata in release name so
364 this package can be distinguished from other vendors.
366 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
367 as determined by configure
369 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
371 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
372 returns no error and no record, the present request is considered
373 partial (only a subset of the records could be returned by backend), and
374 so it is appropriate to set Present Status to partial-4.
378 Move yaz-config man pages to section 1.
380 More documentation about SOLR.
382 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
383 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
384 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
385 peers on some Linux systems. However, in general that does not work
386 so YAZ can not rely on that to work. Debian changed behavior in this
387 respect from Debian lenny to Debian squeeze (still testing as of Oct
389 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
391 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
395 Fix yaz-config output: echo_source not set correctly by configure.
399 SOLR WebService support for yaz-client and ZOOM.
401 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
403 --- 4.0.12 2010/08/17
405 Z39.50 facet support. Facet specifications are passed for search in
406 other-information with ASN.1 as defined in facet.asn and OID
407 .10.1000.81.5 . Facets are expressed as an Attribute list as known
408 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
409 3 is limit (number of entries to get in response). yaz-ztest returns
410 dummy facets if a client asks for them.
412 --- 4.0.11 2010/07/09
414 CCL fixes: bug 2895 and bug 3539.
416 GR1-display: add comma in display - was removed by mistake in
419 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
421 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
423 --- 4.0.10 2010/06/18
425 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
426 result set from a connection. The result set will be on its own
427 thereafter; no operations on it will perform retrievals from a target.
428 Only cached copies are returned.
430 ZOOM C:fix case for HTTP servers responding with Connection:close.
431 Ensure that if there is a current task it is resumed (like fetching
432 more records in a result set) . Bug #3484.
434 PQF parser: use odr_atoi for Odr_int (not atoi)
436 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
437 values that contain any non-digits are treated as string attributes
438 (previously decoding only checked for leading character ([0-9]). PQF
439 encoding: attribute string values are not surrounded by double-quotes.
443 New utility for managing threads - thread_create.h.
445 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
446 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
447 but YAZ' implementation do.
449 Fixes for yaz_cond-functions on Windows 7.
451 DLL export more symbols.
453 zoomsh: show record do NOT render opac.
455 Remove *.la files from Debian and RPM packages.
459 Debian package libyaz-dev depends on libgnutls-dev again (was
460 removed in YAZ 4.0.6, but due to Libtool it is still needed
461 even though yaz-config do not list libgnutls libs).
463 ZOOM: Use only one WRBUF for returning string results for
464 ZOOM_resultset. Reduces memory usage for ZOOM in general.
466 ZOOM: ZOOM_connection do not use a shared pointer to
467 ZOOM_resultset after ZOOM_resultset is destructed by
468 user. Reverts to YAZ 4.0.4 behavior.
472 record-conv: fix problem with at least one XSL conversion -
473 due to probably incorrect usage of XML XSL documents.
477 Fix yaz-config for static mode and the use of SSL (gnutls).
481 Forward decl timeval struct in mutex.h and gettimeofday.h.
483 yaz-config: fix 'static' mode linking.
487 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
488 are wrappers for pthreads or Windows. For Windows these are put in
489 a separate DLL: yaz_cond4.
491 libyaz.la (whole source) is compiled with thread. If thread support
492 is enabled enabled, all source of YAZ is compiled with treading support.
493 This allows core utilities such as yaz_log to use thread facilities.
494 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
495 thread utilities. This commit moves mutex utilities (mutex.c) from
496 libyaz_server.la to libyaz.la.
498 yaz-json-parse displays leading text until error.
502 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
503 patch from Giannis Kosmas.
505 SRU: no longer URL encode SRU database. The URL for an SRU server is
506 a URL and such is alreeady encoded - at least when given with leading
507 http:// or https://. This reverts behavior to YAZ 3.0.50.
509 Support for new MARC XML notation TurboMARC which like MARCXML is a
510 complete representation of MARC/ISO2709.. This one, however, is more
511 compact and allows for faster processing with XSLT. TurboMARC can be
512 used in the marcdisp.h API, from the yaz-marcdump utility and from
515 yaz-ztest can be configured - via the database - to perform certain
516 delays when it performs operations search, present and single record
517 fetch. This allows testers to make yaz-ztest act as a real or even slow
518 Z39.50 server. Refer to the yaz-ztest man pages for details.
522 wrbuf_destroy allows NULL WRBUF passed to it.
524 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
526 Add ZOOM_connection_close.
528 No fixed size buffers for ZOOM shell - bug #3257.
530 tstodr: make it work on s390 platform.
532 New icu iterator-functions. The new icu_iter-functions makes it possible
533 to use ICU chains from many threads.
535 yaz-client: better syntax check for show command.
539 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
542 New simple local-file XML include facility which allows file glob-patterns.
543 Refer to yaz/xml_include.h.
545 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
548 ZOOM_record_get supports new parameter "format" which makes it format XML
551 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
552 JSONText in ECMA-262) is JSONValue, not JSONObject.
556 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
557 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
559 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
560 POSIX/Unix builds .so with major version 4.
562 Remove old LOG_-defines from log.h. They have been obsolete and
563 undefined by default for the last 5 years.
565 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
567 GFS: Remove socket (int *fd) from search_rr handler. The socket
568 descriptor ptr is a facility that allowed a search handler to supply
569 a socket which would serve as a callback - when search was complete.
570 This facility has now been in use for years.
572 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
573 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
574 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
575 returns 'const char *' rather than 'char *. The returned string is
576 read-only and should not be modified by applications. COMSTACK cs_close is
577 now a void function - it no longer returns int. No applications check for
578 the value and the implementations has always returned 0.
580 ZOOM: use size_t for scan hit counts and str size. Functions
581 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
582 occ (hit count) and len (string length) are now of type size_t pointer
583 rather than int pointer. This is to be able to represent large hit counts
584 and to also just to use the proper type for string length (strlen result).
586 New JSON parser. Refer to include/yaz/json.h .
588 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
589 Used to be int in some cases. Many wrbuf_-functions used to return an int
590 indicating some length.. These return values were never used. And so they
593 ODR: odr_malloc, odr_total now takes size_t for size.
595 clone_z_type: fix leak; occurred for encoding failures.
597 --- 3.0.52 2009/12/03
599 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
600 bug was introduced in 3.0.51.
602 --- 3.0.51 2009/12/02
604 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
606 tcpip comstack: fix leak for getaddrinfo.
608 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
609 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
610 Decoding of SRU "path" database is performed by private function
611 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
612 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
614 yaz-client: honor base command for SRU. Change when database setting
615 is applied for SRU and ensure it is kept when a connection is reset.
616 Change also the way errors are displayed or SRU (decoding of packages).
618 --- 3.0.50 2009/11/02
620 Add support for extra request / response data for SRU codecs and GFS.
621 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
622 for extra data response buffer and length. For the GFS, both request
623 and response data (XML) is carried in extra_args and extra_response_data
624 for the search handler. Patch by Ko van der Sloot.
626 ZOOM: For queries that cannot be converted to the specified rpnCharset,
627 ZOOM now returns a diagnostic on the client-side ('invalid query' /
628 10010). This fixes bug #2113.
630 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
631 cmdfile included a 'quit' command that would result in a memory violation.
633 --- 3.0.49 2009/10/01
635 Make a number of functions defined in xmlquery.c static. These have
636 never been declared in a public header file (yaz/xmlquery.h) and was
637 made public by mistake.
639 Improve speed of character conversions (iconv utilities). This makes
640 conversions from MARC-8 faster.
642 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
643 unless type desired is "raw". This will prevent type "xml" from
644 returning ISO2709 .. Which obviously can not be XML parsed.
646 Fix memory leak in ZOOM that would occur if option apdulog was used
647 on a re-used connection.
649 Frontend server logs HTTP requests.
651 Frontend server now sends Z39.50 close when it times out (sesssion has
652 been idle for too long). Versions 2.0.30 and earlier also sent close.
653 But due to a mistake this was disabled in all versions after that, i.e.
654 the server would just close the socket immediately.
656 yaz-client emits a better message when receiving an unrecognised
657 userInformationField.
659 Skip zero-length subfields when decoding ISO2709. This rare case happens
660 if a record has two FS characters in a sequence. Without this patch
661 there would be a reference beyond char array in using_code_len fragments
664 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
666 --- 3.0.48 2009/08/28
668 The show command offered by the zoomsh command now takes a 3d optional
669 parameter type which is what is passed to ZOOM_record. If the type
670 argument is omitted, "render" is used.
672 RPN to CQL conv may use USE string attributes (bug #2978).
674 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
676 --- 3.0.47 2009/07/08
678 Function yaz_xml2query allows a diagnostic element in the PQF XML
679 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
680 code and additional info respectively.
682 The BER BOOLEAN is now the integral type Odr_bool which still happens
683 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
684 typedef'd to Odr_int. This is still an integral 'int', but it may be
685 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
686 ASN-1 compiler as well as programs has been updated to use the new types.
688 --- 3.0.46 2009/06/08
690 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
691 only the bibliographic record was rendered. For type=opac, an OPAC
692 record is only returned if it is present.
694 iconv: small fix for encoding of advancegreek.
696 yaz-client: avoid double display of SRU/SRW records (bug #2798).
698 yaz-client: option auto_reconnect=on really reconnects.
700 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
702 server: avoid null ptr ref for for yaz_poll errors.
704 build: fix RPM build for RHEL 5.3.
706 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
708 --- 3.0.45 2009/03/31
710 Fixed bug #2709: TCP connect returns Invalid argument.
712 Fixed compilation for mingw.
714 Honor charset for raw records (ZOOM_record_get).
716 Fixed use of errno for threaded mode that was seen on Solaris 10.
718 Fixed argument passing with blanks in value for Windows Service.
720 Disable YAZ' own log rotate by default (no 1 GB limit).
721 The variable l_max_size which specifies the log file limit is set to 0
722 (DISABLED): This is due to the fact that YAZ is most often deployed using
723 logrotate. Also YAZ can not perform log rotate because of unsufficient
724 permissions (setuid).
726 --- 3.0.44 2009/02/17
728 List supported encodings in man page for yaz-iconv.
730 Fixed missing SSL libs for --libs output
732 Re-established OID record syntax application-xml. Nobody should use it
733 but we don't want to change soname because of this symbol being absent.
735 --- 3.0.42 2009/02/02
737 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
739 Added member named_result_sets for init handler struct for the GFS. This
740 allows a server to disable named result sets.
742 Removed OID record syntax application-xml.
744 Added support for rule-based transliterator for ICU wrapper of YAZ.
746 Fixed bug #1902: yaz-icu XML output.
748 Make YAZ checks Emacs friendly.
750 BITSTRING value shows value. Bug #2346.
752 ISO2709 decoding: skip control characters from indicator data.
754 Omit sort key by default in yaz-icu's output.
756 Allow combined single char options (again) for YAZ' options function.
758 Utility yaz-marcdump got option to display YAZ version (-V).
760 Allow YAZ to use ICU 3.4.
762 Added new ICU test case which illustrates removal of diacritics.
764 --- 3.0.41 2008/12/29
766 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
768 --- 3.0.40 2008/12/29
770 For configure, using option --without-xml2 also disables Libxslt/Libexslt
773 Fixed bug #2352: yaz-marcdump crashes for certain record.
775 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
777 Added support for Danmarc2 to UTF-8 conversion.
779 Added support for ISO5426 to UTF-8 conversion.
781 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
782 implementation version.
784 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
786 --- 3.0.38 2008/11/10
788 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
789 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
791 ZOOM C now interprets databaseName option for ZOOM connection as path
794 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
796 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
798 Dummy Libxml2 types no longer defined in headers of YAZ'.
800 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
803 --- 3.0.36 2008/09/26
805 Various ODR chapter fixes.
807 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
809 Added missing source for Windows compilation, mutex.c.
811 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
813 For SRU connections in ZOOM all records up to "count" are now fetched.
815 Fixed crash in generic frontend server (and yaz-ztest) which occurred
816 in Windows due to bad error handling for Libxml2.
818 Added facility for sending arbitrary records (ASN.1 any) using
819 ZOOM C's Extended service update. Patch by Sam Reynolds.
821 New options for ZOOM C's connection, logapdu which makes ZOOM log
824 --- 3.0.34 2008/06/18
826 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
828 --- 3.0.32 2008/06/12
830 Fixed memory violation that could occur when decoding UTF-8. This bug
831 was only present in 3.0.30 of YAZ.
833 --- 3.0.30 2008/06/06
835 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
836 GNU TLS is used by default (if found).
838 yaz-ztest returns OPAC records if a client asks for OPAC.
840 Improved speed of MARC-8 encoding.
842 Added support for lossy and loss-less MARC-8 encoding.
844 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
846 Added new Windows Service wrapper (sc).
848 yaz-client's itemorder command may now send a file.
850 Fixed yaz-marcdump to allow the use of NS prefix for record element.
852 Added new function yaz_log_xml_errors.
854 Allow (but warn) unknown XML attributes in MARCXML parsing.
856 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
858 The UTF-8 to MARC-8 conversion now uses a different set of characters
859 for Greek symbols. Bug #2120.
861 --- 3.0.26 2008/02/21
863 Added yaz_daemon (daemon.h).
865 Fixed bug #2068: pkg-config trouble
867 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
869 --- 3.0.24 2008/01/28
871 Document --with-xml2 option.
873 Added OPAC XML XSD (etc/opacxml.xsd).
875 Allow glob mask for name attribute in retrieval element for the
876 generic frontend server's retrieval facility.
878 Changed yaz_poll_poll to return yaz_poll_except for all returned events
879 except POLLIN/POLLOUT.
881 Fixed error handling in cs_listen. Bug #2037.
883 --- 3.0.22 2008/01/20
885 Fixed version in yaz/yaz-version.h.
887 Fixed bug #2027: Crash when closing connection.
889 Changed configure so that ICU support is only enabled if only ICU
890 and Libxml2 is available (because the ICU chain is XML based).
892 --- 3.0.20 2008/01/15
894 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
895 is built. Only this DLL depends on the ICU runtime.
897 yaz-ziffy is no longer part of YAZ. It is distributed separately by
898 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
900 Changed license of CCL module to 'Revised BSD'. After consultation with
901 remaining members of the original EUROPAGATE consortium, we are re-issuing
902 the CCL module without a separate license. The software was developed by
903 Index Data as part of a research project. The special license was included
904 to help feed usage information back to the project consortium to support
905 project evaluation. At this time, the project consortium has long-since
906 disbanded, and the majority of the original principals have retired. At the
907 same time, we have significantly modified the software during the following
908 years, to the point where very practically no original code remains. To
909 simplify re-use of the software, we have contacted those members of the
910 consortium who could be reached, and agreed to re-issue the module as a
911 proper part of the YAZ package.
913 Tcl scripts uses /usr/bin/tclsh as preferred shell.
915 CQL closer to being version 1.2 compliant. CQL also allows free-form
916 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
919 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
920 bug could make Extended services handling crash in the ZOOM layer. This
921 bug was only present in YAZ 3.0.18.
923 --- 3.0.18 2007/12/19
925 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
928 yaz-marcdump reads and writes collection wrapped records.
930 Handle OPAC for record conversion module.
932 Fixes for ICU wrapper.
934 Allow ICU libs to be controlled with --with-icu .
936 --- 3.0.16 2007/11/12
938 Added yaz_poll which is a wrapper for select/poll. When poll is available
939 and non-buggy, it is used, by yaz_poll . This allows more than 1024
940 sockets to be in use.
942 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
943 functionality through an XML based configuration (ICU chain). This system
944 is useful for search facilities such as Pazpar2 and Zebra that needs to
945 perform tokenization of indexed material. The ICU code in a separate
946 library libyaz3_icu.a.
948 Added HTTP tunnel facility for COMSTACK, bug #1752.
949 This is a facility that allows a Web proxy, such as squid, to tunnel
950 Z39.50 traffic. This facility is "transparent" to must applications
951 using YAZ. It's enabled by using pseudo transport connect: followed by
952 the proxy address, followed by command, then follwed by he regular
953 "virtual" addresss. For example,
954 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
956 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
958 --- 3.0.14 2007/09/21
960 Fixed bad memory reference in ZOOM_record - cuased by member not being
961 initialized. This was a problem only in YAZ 3.0.12.
963 Fixed bug in conversion from MARC to XML: Non-XML characters in control
964 fields were not removed.
966 Changed the way C code is generated from codetables.xml. Made a MARC-8
967 conversion trie for each characterSet section rather than codeTable.
968 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
969 of codetables.xml from Larry Dixson, LOC. Bug #1464.
971 --- 3.0.12 2007/09/12
973 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
974 from ZOOM_record_error).
976 ZOOM C function ZOOM_record_get returns record schema for type="schema".
978 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
980 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
982 Better SRW-to-Bib-1 diagnostic mapping.
984 ZOOM C and yaz-client announces SRU version 1.2 by default.
986 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
989 Fixed in yaz_sru_decode to allow other version than 1.1.
991 --- 3.0.10 2007/08/22
993 Added support for SRU scan for ZOOM.
995 Added support for the use of the older versions or Extended Service
996 Update in ZOOM. To faciliate this, an option "updateVersion" may be
997 set to the version , 1=first, 2=second, 3=third. The third version is
998 what ZOOM C has used so far. And that, obviously, is the default.
1000 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1001 therefore in Zebra and in SimpleServer-based applications). The new
1002 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1003 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1004 which is passed into the back-end search callback function.
1006 Added support for HTTP Basic authentication in clients: the SRU/W
1007 codec encodes the username/password elements of the PDU structure
1008 appropriately, and these may be set using the "user" and "password"
1009 options in ZOOM-C applications (the same options that are used for
1010 Z39.50 authentication).
1012 --- 3.0.8 2007/06/25
1014 Fixed bug #1208: SSL appears to be broken in ZOOM.
1016 Fixed bug #1206: Libxml2 include path weirdness.
1018 Added oid_name_to_dotstring.
1020 Allow elementSetName to be specified for ZOOM C record update.
1022 Allow waitAction to be specified for ZOOM C based for Extended Services.
1024 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1025 syntax OID. Bug introduced in YAZ 3 series.
1027 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1029 --- 3.0.6 2007/06/06
1031 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1032 directory. yaz-client now reads commands from file given by option -f
1033 if specified; then tries to read .yazclientrc in current directory.
1034 Failing that, it reads .yazclientrc from user's home directory.
1036 Added support for correlationInfo Note and ID for Record Update via
1039 Added yaz-client command querycharset which specifies character set for
1040 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1041 (termListAndStartPoint).
1043 Charset ISO5428:1984 is an alias for ISO5428-1984.
1045 Implemented a way to perform scan in a result set using Z39.50. This
1046 is achieved by attaching the result set name in the characterInfo
1047 (type InternationalString) of OtherInformation in the Scan Request PDU.
1048 The result set is identified in the otherinformation by the new OID:
1049 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1050 This allows for scan in result set and faceted search . Zebra did some
1051 of this in the APT term using attribute type 8 and value being result
1052 set. Using the OtherInformation approach for this is cleaner and easier
1053 to work with in proxies and the like. This facility can be used in
1054 yaz-client using new command setscan which takes a result set as first
1055 argument, start position (APT) as second.
1057 Changed decoding of SRU XML packed records to deal with servers that
1058 have recordData with XML data with multiple root nodes. Also make
1059 comparison for recordPacking case insensitive. Again, one server
1060 returns "XML" where others return "xml".
1062 For SRU responses allow Content-Type application/xml as well as text/xml.
1064 --- 3.0.4 2007/05/21
1066 Fixed bug in character set conversion of BER strings. Bug introduced
1069 --- 3.0.2 2007/05/08
1071 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1073 For OID class, use oid_class consistently.
1075 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1078 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1079 character set for bibliographic information interchange". By Giannis Kosmas.
1081 Added documentation on new OID API.
1083 --- 3.0.0 2007/05/02
1085 Changes to generic frontend server interface: added new member
1086 'query_charset' for bend_initrequest structure. A backend init handler
1087 should set this member to its native character set for query terms.
1088 When defined, the frontend server logic will announce this character set
1089 to a client if the negotiationModel bit is set by the client. All server
1090 implementors are encouraged to specify this. If a backend server does not
1091 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1093 Added CCL utility to remove terms (stop words) from resulting RPN
1094 tree. This is handled by functions with prefix ccl_stop_words_ .
1096 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1097 terms in RPN queries.
1099 Clean-up the CCL API. Moved some internal structures from ccl.h to
1100 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1101 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1102 This is replaced by ccl_parser_find_str which takes a string instead.
1104 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1105 libyaz.la is the core of YAZ except the generic frontend server and
1106 does not depend on POSIX threads anymore. libyaz_server.la is the
1107 generic frontend server facilities and uses POSIX thread functionality
1108 if available. The libyaz.la no longer depends on POSIX threads because
1109 the number of global structures is limited. NMEM no longer re-uses blocks
1110 between threads ; it simply free's memory immediately but allocates in
1111 "large" chunks as usual. We don't expect any performance penalties
1112 because of this. The yaz_log system is still using a global log_level so
1113 caution must be taken when modifying it with yaz_log_init_.. +
1114 yaz_log_mask_str. This, however, should not cause any trouble because
1115 these functions are called during initialization of application code
1116 anyway. `yaz-config --libs server` returns libs for server applications;
1117 `yaz-config --libs` returns libs for non-server applications.
1119 New OID database - with public definitions in oid_db.h. Removed old OID
1120 database including the head oid.h and definitions such as enum oid_value
1121 and struct oident. The new OID database uses the same string names as
1122 before but the 'protocol' is gone. There are now only two representations
1123 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1124 converts from string to OID; functions with prefix yaz_oid_to_string
1125 converts the other way.
1127 Change to emit_term() in CQL-to-PQF query translation: when a term has
1128 the /regexp relation modifier, do not process it for leading and
1129 trailing "^" and "*", which have quite different meanings in regular
1132 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1133 write handlers no longer carries a 'last' parameter. This will make
1134 yaz_iconv flush "less" characters. A flush is performed by call to
1135 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1137 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1138 removed, because function yaz_query_to_wrbuf does the same.
1140 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1141 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1143 Deprecated MARC utility functions removed.
1145 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1148 Branch split: YAZ_2_1_55_branch
1150 --- 2.1.54 2007/03/16
1152 Fix to ZOOM-C so that transparent reconnection is properly handled on
1153 connections that are in asynchronous mode.
1155 Fixed compilation on OpenBSD 4.0.
1157 Large strings in GRS-1 records are now properly displayed in yaz-client.
1159 Added character conversion support for "advancegreek"; based on patch from
1162 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1163 sequence is met. Before the error was not set so it would be unknown.
1165 Adjust yaz-marcdump MARC reader so that it skips until record separator
1168 --- 2.1.52 2007/03/07
1170 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1171 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1172 fd_set structure used as a bitmask for the FDs to be selected on.
1174 Using ACX_PTHREAD macro to check for POSIX threads.
1176 Fixed have-vsnprintf check.
1178 --- 2.1.50 2007/02/23
1180 Fixes for configure on BSD. Bug #900.
1182 Added snprintf/vsnprintf wrappers for systems that don't have
1183 limits (heavens forbid).
1185 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1186 created before all previous tasks were completed and removed from the
1187 task queue, the new task could be removed by a mistake.
1189 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1191 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1193 Fixed bug #832: Problem with MARC/charset in yaz-client.
1195 Fixed bug #668: save command line history for yaz-client.
1197 Fixed bug #830: pkg-config support.
1199 --- 2.1.48 2007/01/23
1201 Extended ZOOM result set options with two options that may be read by
1202 a client: resultSetStatus and presentStatus with values as specified for
1204 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1206 Fixed bug #827: Using SSL fails on Debian etch.
1208 Fixed bug #826: Weird looking chars for set of MARC records.
1210 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1211 that is treated as an ItemOrder with itemRequest being an XML document
1212 external. The value of "doc" is the content.
1214 Extended the GFS search facility. New member of bend_search_rr
1215 'estimated_hit_count' signals that hits is known to be an estmate
1216 (higher or lower than real hit count). New member 'partial_resultset'
1217 signals that the search was partial (hit count is lower or equal than
1218 real hit count). For Z39.50, the information is stored in resultSetStatus
1219 member of SearchResponse APDU. For SRU, the information is signalled
1220 via SRU diagnostic 59: "Result set created with valid partial results
1223 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1225 --- 2.1.46 2007/01/13
1227 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1229 Added ZOOM_connection_peek_event.
1231 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1232 the following new functions:
1233 ZOOM_event_nonblock, ZOOM_connection_process,
1234 ZOOM_connection_get_{socket,mask,timeout},
1235 ZOOM_connection_fire_event_{timeout,socket}.
1236 The existing blocking event handler, ZOOM_event, is a wrapper for the
1237 + blocking ZOOM_event_sys_{poll,select}.
1239 Implemented function ccl_xml_config which parses XML version of CCL
1240 configuration (bug #798).
1242 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1244 Added timings utility (yaz/timing.h)
1246 --- 2.1.44 2007/01/03
1248 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1251 Fixed bug #779: Rotation of apdu.log fails.
1253 Fixed for character set conversions:
1254 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1255 Honor G1 set in MARC-8 decoding.
1257 --- 2.1.42 2006/12/17
1259 Fixed bug #775: char conversion does not handle Alternative UTF-8
1262 Implemented function yaz_marc_read_line which parses MARC line format
1263 records. There is a wealth of formats out there. So far, this function
1264 reads line records produced by yaz_marc_write_line.
1266 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1267 more generic and easier to remember(!) options: -i format and -o format
1268 which specifies input format and output format respectively - where
1269 format is one of "marc", "marcxml", "line", "marcxchange".
1271 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1272 does not print anything except warnings for records.
1274 For yaz-marcdump, added support for MARC split into files (-s) with a given
1277 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1278 spec, at http://www.loc.gov/standards/sru/record-update/
1279 This has changed the binary layout of the following structs:
1280 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1281 bend_update_rr . Patch by Ko van der Sloot.
1283 Added GFS utility function bend_assoc_is_alive which returns 1 if
1284 association is still alive (client is connected); 0 otherwise (client
1285 closed connection). This allows busy servers to stop working for
1288 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1289 been a separate piece of software. This version of ziffy has been modified
1290 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1292 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1294 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1295 Client code may now interrogate options such as "init_opt_sort" to
1296 find out whether the server claims to support various options.
1298 --- 2.1.40 2006/11/27
1300 Added utilities yaz_{set,get}_esn to set/get element set name from
1303 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1304 of YAZ and has been so since YAZ 2.1.10.
1306 Implemented ZOOM_record_error which returns error information for
1307 record (surrogate diagnostic).
1309 --- 2.1.38 2006/10/31
1311 Updates for SRU Update by Ko van der Sloot:
1312 1. Changed name from "operation" to "action"
1313 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1314 versions in the code, marked as 'backward compatible'.
1315 3. Added diagnostics for SRU Update.
1317 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1319 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1321 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1323 For GFS, fixed problem with SRU diagnostic 'First record position out of
1324 range' being issued for 0 hits.
1326 zoomtst10 part of Windows Build.
1328 --- 2.1.36 2006/10/13
1330 Implemented yaz_filepath_comp which splits a path into file path
1331 components (required by Zebra 2.0.3+).
1333 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1334 BSD inspired license until now so this should not have any real impact on
1335 anybody. See http://www.opensource.org/licenses/bsd-license.php
1337 Fixed bug #687: Missing log lines.
1339 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1342 Fixed bug #689: SRU diagnostics to be added.
1344 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1345 whether a connection is idle (no more work do do).
1347 --- 2.1.34 2006/10/04
1349 Change type of optval from long to int for invocation of setsockopt with
1350 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1352 Added support for specifying the max log file size for the Generic
1353 Frontend Server. The size is given with option -r.
1355 --- 2.1.32 2006/09/21
1357 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1359 --- 2.1.30 2006/09/17
1361 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1364 Fixed bug in Generic Frontend Server that could cause a server to stop
1365 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1367 For the generic frontend server, the maximum record size is used as maximum
1368 size of incoming packages (SRU + Z39.50). The value until was previously
1369 only used in Z39.50 Init negotiation and, later, in a session controlled
1370 sizes of records returned. This is controlled using -k option. It can be
1371 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1373 --- 2.1.28 2006/09/04
1375 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1378 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1380 New option for yaz-marcdump -lpos=value which allows setting a portion
1381 of MARC header to a certain value.
1383 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1385 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1386 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1388 --- 2.1.26 2006/08/15
1390 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1393 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1395 --- 2.1.24 2006/08/08
1397 Fixed MARC ISO2709 encoding routines to deal with character set
1400 Minor changes to GFS logging. Database included in search request log
1403 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1404 cached/multiple records.
1406 Shared libraries are built by default on Unix+configure.
1408 Changed cql2pqf transformation to use a different evaluation order. The
1409 new order is: always, relation, structure, position, truncation, index
1410 and relationModifier. Old order was: always, relation, relationModifier,
1411 structure, index, position, truncation. Note that the the latter ones
1412 override former ones for identical attributes.. The new scheme means that
1413 it is possible to override any existing attribute with a relationModifier.
1414 And also that it is possible to override everything for the index rule
1415 (except the ones listed in relationModifier). No order is perfect but this
1416 one, we believe, covers more real cases.. The "always" should have been
1417 called "default", since the attributes there can be overridden with all
1420 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1421 compilation phase, but also for yaz-config --cflags output. This allows
1422 us to have public headers with Libxml2 stuff in them . It should also,
1423 eventually, make Libxml2 checks redundant in packages using YAZ, such
1426 --- 2.1.22 2006/06/15
1428 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1429 stored in uri, message and details.. Previously diagnostics were stored
1430 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1431 compatibility.. but he's probably the only one affected, so.
1433 Added support for CCL, compiled on the client side, in ZOOM-C. This
1434 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1435 input; the resulting query objects can be used for for searching with
1436 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1438 YAZ' configure searches for OpenSSL by default.
1440 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1441 SL_CTX_use_certificate_file. See
1442 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1443 for more info. Thanks to Ko van der Sloot.
1445 --- 2.1.20 2006/06/02
1447 Bug #600: SRU GET, POST support for yaz-client. Introduced
1448 command 'sru' which selects method SOAP/GET/POST.
1450 Allow missingValueAction to be specified for the sortspec string -
1451 function yaz_sort_spec. By default, the missing value action is null.
1452 Use ! to specify "abort". Use = followed by stringvalue to specify default
1455 Ensured that Present-handler (if defined) is called in GFS before any call to
1456 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1457 searchRetrieve requests.
1459 Documentation for YAZ is now based on the Docbook XML/XSLT using
1460 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1461 is no longer depending on jade/openjade or docbook-to-man scripts.
1462 PDF is no longer part of the distribution - but can optionally be
1463 made using DSSSL/jadetex or FOP.
1465 Added retrieval handling support in Generic Frontend Server to support
1466 conversion between MARC/XML as well as XSLTtransforms. See
1467 etc/yazgfs.xml for an example.
1469 Added Authentication support to Generic Frontend Server in SRU
1470 mode. Authentication using HTTP Basic is supported, as is the use
1471 of 'x-username' and 'x-password' parameters in the request itself.
1473 Added support for a new character set MARC8s identical to MARC8 except
1474 that it converts combined characters to single Unicode characters in the
1475 Latin-1 range (when possible).
1477 --- 2.1.18 2006/04/24
1479 ASN.1 compiler 0.4: generates brief Doxygen file header for
1480 generated .h/.c files.
1482 Utility yaz_iconv now supports conversion to MARC-8.
1484 New facilities for the MARC module. The reading - and writing of
1485 content are separate methods for the yaz_marc_t handle. The following
1486 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1487 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1488 format). Write functions have prefix yaz_marc_write_.. The existing
1489 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1490 available. Removed support for OAI-MARC and simplexml (not the
1491 simplexml from PHP5).
1493 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1494 to be returned for this connection.
1496 --- 2.1.16 2006/03/31
1498 Allow multiple languages and charsets to be specified with
1499 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1500 negcharset iso-8859-1,utf-8
1502 Translation of proximity nodes from CQL into PQF now works.
1504 Moved to automake 1.8, 1.9.
1506 Added function yaz_log_set_handler which allows a log handler to be
1507 installed. This handler will be called for all log messages. Output
1508 to file is also produced; but that can be disabled by passing NULL
1509 fname to yaz_log_init_file.
1511 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1513 For SRW (including GFS), accept application/soap+xml as content-type
1516 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1517 produces NO stylesheet reference even if a default stylesheet is specified
1520 --- 2.1.14 2006/03/14
1522 Updated Windows package to include yazd.dll + yazd.lib for the
1523 Development component.
1525 If the environment variable YAZ_LOG is set, then it is used as a
1526 string indicating the default level of logging to use if not
1527 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1528 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1529 used as before. So, for example, to omit warnings from YAZ logging,
1530 export YAZ_LOG=-warn
1532 cql_transform() now map structure and other attributes before indexes,
1533 so that index-specific structures and other attributes can override
1534 defaults. So now a combination of mapping specifications such as:
1536 index.dc.date = 1=date-modified 4=5
1537 does the right thing.
1539 cql_transform() now also respects the "always" mapping specification,
1540 which establishes an initial set of attributes to be used for all
1541 terms except where overridden by more specific attributes associated
1542 with the index, relation or modifier.
1544 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1545 which mode to use; one of "post", "get" or "soap" (SRW, default).
1547 Fixes for yaz_iconv routines: changed trie-based character set conversions
1548 to use only non-negative values for bit fields due to Sun's C compiler not
1549 supporting negative values.
1551 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1552 sequences where not read correctly. Fix by Rustam Usmanov.
1554 Updated win/makefile to use options, settings which makes things
1555 compile with VS C 2005.
1557 --- 2.1.12 2006/02/01
1559 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1561 In ZOOM socket code, use select instead of poll on MacOSX.
1563 ZOOM-C now support client-side compilation of CQL into RPN that is
1564 sent to the server, enabling CQL to be used against all Z39.50
1565 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1566 ZOOM_query object, and submit it using ZOOM_connection_search().
1567 The CQL-to-RPN translation uses a configuration file, the name of
1568 which must be specified in the Connection's "cqlfile" option.
1570 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1571 function, which takes as its start-term parameter a ZOOM_query object
1572 (which may have had either CQL or RPN set into it).
1575 --- 2.1.10 2005/11/29
1577 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1578 GFS to support this as well. Backend handler, bend_srw_update, does the
1579 update work. Code contributed by Ko van der Sloot.
1581 Allow retrieval of Search Result-1 information in ZOOM by the use of
1582 options that are attached to a result set. ZOOM documentation updated
1585 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1586 UTF-8 conversion. Patch by Raj Patel.
1588 Added option -m to GFS to control formatting of timestamps in log file.
1590 Added 'exit' as synonym for 'quit' in yaz-client
1592 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1593 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1594 for the new members. Patch by Ko van der Sloot.
1596 Added support for SRU POST. It is supported for content-type
1597 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1599 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1600 Instead make the library libyaz.la multi-threaded. Threading as a whole
1601 can still be disabled by configure option --disable-threads. Previosly,
1602 with older GLIBCs there were problems with MT libs under Apache. This
1603 has now been fixed a long time ago.
1605 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1608 CQL module modified to be case insensitive for relations/indexes/operations.
1610 Fixed bug in CQL transform code: incorrect value relationModifieder
1613 Added 'show all' command for yaz-client which retrieves all results
1616 Added new yaz-client, xmles, which takes a (private) OID and
1617 a document to be sent as an extended service request.
1619 Describe new yaz-client commands wait_response and set_auto_wait.
1621 Increase TCP/IP listener backlog from 3 (which I am guessing was
1622 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1623 that the socket will queue as many incoming connections as it's able
1624 to handle ongoing connections. In other words, it will never now
1625 refuse a connection that it would be able to handle merely because
1626 it's not got around to accepting() enough of the pending connections
1627 yet. This is the behaviour anyway under Linux, where the listen()
1628 argument is ignored; but not under BSD and on systems such as
1629 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1630 YAZ-based servers should now be uniform across operating systems in
1633 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1634 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1635 This allows yaz-marcdump to read large MARC batches (>2 GB).
1637 Modified all YAZ source files - except the source which is auto-generated
1638 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1641 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1642 corresponding to the existing *_setl() function. These allow option
1643 values containing arbitrary valuues.
1645 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1646 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1647 except that it returns an indicator of whether or not the sort
1648 criterion was accepted (0 for OK, -1 for invalid).
1650 --- 2.1.8 2005/06/07
1652 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1653 MARC output rather than returning "new" buffer.
1655 yaz-client warns about unknown init options.
1657 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1659 --- 2.1.6 2005/05/24
1661 Added support for SRW sort in Generic Frontend Server. Patch
1662 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1663 sortKeys - or NULL if none is provided.
1665 Fixed bug #307: It was impossible to specify indefinite/no timeout
1666 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1669 Added support for multiple languages and charsets to be specified in
1670 ZOOM. Each charset/language is separated by a blank. If negotiation is
1671 in effect in init-response, Option
1672 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1673 Code based on patch by Vasiliy Osadchuk.
1675 Fixed bug #306: infinite recursion that occurred when calling
1676 yaz_log_level_init as the first call (before other log level or
1679 Fixed bug in scan handling in front end server: if preferred-Position-In-
1680 Response was non-present, a NULL pointer referece was performed.
1682 --- 2.1.4 2005/04/26
1684 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1685 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1686 now defined for all those error codes. So instead of putting 109 in
1687 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1688 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1690 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1693 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1695 Program yaz-client now exits and produces an error message if multiple
1696 Z39.50 servers are specified on the command line (none or one allowed
1699 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1702 --- 2.1.2 2005/03/16
1704 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1706 Fixed bug #272: Preserve spacing for CCL terms.
1708 --- 2.1.0 2005/03/14
1710 Added support for virtual hosts and multiple backend servers for
1711 the YAZ frontend server. The configution is XML based and
1712 support specificition of CQL to RPN mappings and explain information.
1713 See section "Virtual Hosts" in the YAZ manual.
1715 Extended OPAC display utility. OPAC display utility renders
1716 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1717 to supplement yaz_marc_decode_wrbuf.
1719 Fixed a bug in MARC decoder that could caused it to crash for some
1720 invalid MARC records. More diagnostics and warnings where added in
1721 XML output (warnings, etc are stored in comments).
1723 --- 2.0.34 2005/02/08
1725 Fixes for UNIX domain sockets. Bug #261.
1727 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1729 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1730 Added yaz_marc_subfield_str which defines subfield lead string which is
1731 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1732 yaz_marc_endline_str which defines end of fields string used in
1733 YAZ_MARC_LINE format. Default string is newline.
1735 Experimental support for MarcXChange. This format can be produced
1736 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1737 http://www.bs.dk/standards/MarcXchange.xsd
1739 Added yaz-client commands scansize that sets maximum number of
1740 entries to be returned by scan.
1742 --- 2.0.32 2005/01/11
1744 Added support for SRW scan in yaz-client and Generic Frontend Server.
1746 * Added whereInList member to SRW Scan Term.
1748 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1750 Fixed NMEM system to return aligned blocks on the smallest boundaries
1751 that are suitably aligned for all possible types on the particular
1752 architecture YAZ is being built for.
1754 --- 2.0.30 2005/01/04
1756 Fixed numerious warnings that was issued with newer versions of GCC.
1758 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1759 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1762 Make YAZ Generic Frontend Server slightly faster.
1764 Enhance (and reduce) logging for Generic Frontend Server.
1766 Revert YAZ log system so that it flushes every write operation
1767 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1769 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1770 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1771 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1772 will effectively disable old definitions.
1774 --- 2.0.28 2004/11/09
1776 Added yaz_log_time_format which specifies log format using
1779 Added yaz_log_module_level which returns mask for a module. Value
1780 is non-zero mask a if module is enabled; zero if disabled.
1782 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1783 in include/yaz/cql.h.
1785 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1787 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1789 Fixed bug #172: RPM builds does not enable SSL.
1791 Doxyfile.in part of dist. Doxyfile generated by configure.
1793 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1794 are given and the corresponding component does not exist.
1796 Extend CCL documentation in YAZ reference. Describe r=r.
1798 --- 2.0.26 2004/10/01
1800 Fixed MARC->MARCXML conversion to properly deal with
1801 fields, subfields, indicators having non-ASCII characters.
1803 Fixed MARC->MARCXML conversion so that ASCII control characters
1804 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1807 Added YAZ GFS support for conversion from Z39.50 surrogate
1808 diagnostics to SRW surrogate diagnostics.
1810 Bug fix: YAZ GFS did not return schema in explainResponse.
1812 --- 2.0.25 2004/09/30
1814 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1815 now converts recordSchema to elementSetName as well as schema URI.
1817 Fixed bug in COMSTACK that prevented HTTP request packages from being
1820 --- 2.0.24 2004/09/29
1822 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1823 does not require white-space before and after the dash in a range, e.g.
1824 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1827 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1828 due to new GCC removing "redundant" code.
1830 Added yaz-client commands scanpos and scanstep that sets preferred
1831 position and step-size for scan.
1833 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1835 Added CCL utility ccl_qual_buf which parses one or more CCL
1836 spec lines in a buffer.
1838 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1839 of name and value - ignoring empty lines and comments.
1841 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1843 Added odr_get_element_path which returns current element path for an
1844 ODR handle. This utility is useful in error handling or user-defined
1847 Added ODR_PRINT utility odr_set_stream which is is a more generic
1848 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1849 to a write function and pointer to close function. The close function - if
1850 non-NULL - will be called during odr_destroy.
1852 Fixed bug in CCL parser where truncation char was not removed from
1853 right side when truncation=both was in effect.
1855 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1858 --- 2.0.23 2004/08/11
1860 Fix buffer overrun in CQL parser when dealing with proximity (%).
1862 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1863 to UTF-8/UCS conversion is now only based on codetables.xml.
1865 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1867 --- 2.0.22 2004/08/06
1869 Add support for more "commit changes" in ZOOM (uses Extended Services).
1871 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1874 Yet another small fix for configure of SSL.
1876 --- 2.0.21 2004/05/14
1878 Fix SSL libs for configure when --with-openssl=DIR is given.
1880 --- 2.0.20 2004/05/10
1882 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1884 SSL comstack now uses yaz.pem certificate file on server side
1885 by default. Certificate filename can be configured by calling
1886 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1888 Fix bug regarding multiple calls to ZOOM_connection_connect.
1890 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1892 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1893 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1895 ZOOM now allows inspection of X509 peer certificate for verification.
1896 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1898 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1899 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1900 as "modular" but it simplifies things.
1902 Added cs_get_peer_certificate to that returns peer X509 PEM.
1904 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1905 NULL if SSL is unavailable.
1907 Documentation about MARC decoding tools.
1909 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1911 --- 2.0.19 2004/03/30
1913 Rename CHANGELOG to NEWS to follow GNU style packing.
1915 Fix bug with missing initialization of member in init_diagnostics.
1916 This bug affects threaded version of GFS server.
1918 --- 2.0.18 2004/03/20
1920 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1923 Ensure zlib.dll is packed with Windows install.
1925 --- 2.0.17 2004/03/17
1927 Fix encoding of xsd:string to use text instead of CDATA.
1929 Fix endless loop in CQL parser with unbalanced ".
1931 Use a more compact way to store MARC-8 conversion tables.
1933 --- 2.0.16 2004/03/16 Debian only
1935 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1938 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1943 --- 2.0.15 2004/03/01
1945 Another fix for decoding of XML packed records.
1947 --- 2.0.14 2004/02/25
1949 Fixes for Chunked encoding. White space not ignored after length spec.
1951 Update NS and use default NS for SRW diagnostic elements.
1953 --- 2.0.13 2004/02/23
1955 Implement ZOOM_resultset_cache_reset which resets record cache.
1957 Implement ZOOM_resultset_sort which sorts a result set.
1959 Implement chunked HTTP transfer.
1961 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1963 --- 2.0.12 2004/02/16
1965 Added member 'schema' to bend_explain_rr structure so that backend
1966 can specify explain record identifier. Defaults to Zeerex 2.0.
1968 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1970 --- 2.0.11 2004/02/16
1972 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1975 Added init command for yaz-client which sends "extra" init request.
1977 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1978 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1980 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1982 Make ZOOM error code for "invalid query".
1984 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1986 --- 2.0.10 2004/02/05
1988 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1991 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1993 Added option -p <file> to make Generic Frontend Server to write PID file.
1995 Added option -D to put Generic Frontend Server in background on its own.
1997 Make ZOOM C recognize option "password". If unset, "pass" is used
1998 (for backwards compatibility).
2000 Fixed a bug in Generic Frontend Server that could make it crash if a
2001 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2004 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2005 Must be issued before open, in order to be in effect.
2007 --- 2.0.9-6 2004/01/12 Debian/Windows
2009 Make the SRU server more picky WRT unknown params, etc.
2011 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2013 New YAZ client command, options, that sets Z39.50 options.
2015 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2016 options from a string of tokens (one token for each option bit).
2018 Update SRW diagnostic code messages.
2020 --- 2.0.9-5 2004/01/07 Debian/Windows
2022 Handle user defined stylesheet for SRW/SRU.
2024 --- 2.0.9-4 2004/01/06 Debian/Windows
2026 Fix bug in decoding of Content-Length.
2028 --- 2.0.9-3 2004/01/06 Debian/Windows
2030 Fix a bug with decoding of XML packed records.
2032 --- 2.0.9-2 2004/01/05 Debian only
2034 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2036 Fix bug in SRW/SRU diagnostics decoding.
2038 --- 2.0.9 2004/01/05
2040 Fixed bug in Generic Frontend Server which could drop records exceeding
2041 preferred message size. Reported and fixed by Irina Dijour.
2043 Fixed calculation of package size for structured records in Generic
2044 Frontend Server. Reported and fixed by Irina Dijour.
2046 Fixed namespace for SRW/SRU diagnostics.
2048 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2050 --- 2.0.8 2003/12/22
2052 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2053 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2056 CQL changes to reflect recent changes to the specification:
2057 * Documentation talks about context sets instead of index sets.
2058 * Documentation talks about indexes instead of qualifiers.
2059 * The CQL-to-PQF transformer's configuration file now uses
2060 "index.set.name = <attributes>" instead of the old form
2061 "qualifier.set.name = <attributes>". (Both forms are still
2062 understood but the latter is deprecated.)
2063 * CQL terms with no explicit index specified are now interpreted as
2064 cql.serverChoice instead of srw.serverChoice (which of course
2065 behaves exactly the same.)
2067 --- 2.0.7 2003/12/16
2069 MARC conversion can now generate ISO2709 output in another
2070 character set. yaz-marcdump uses this facility if you invoke it
2073 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2074 functions from there can be used from C++.
2076 --- 2.0.6 2003/12/04
2078 Frontend server now transfers memory from decoded packages to stream
2081 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2082 references to show up.
2084 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2085 the ZOOM Abstract API. The older names for the same options are still
2086 also supported for the benefit of old applications.
2088 ZOOM-C supports "implementationId" and "implementationVersion" options
2089 to go along with "implementationName". These allow the user code to
2090 specify identification strings to be sent to servers.
2091 Add OID for the new ExtLite attribute set.
2093 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2094 as requested/supplid by Ere Maijala <ere@atp.fi>
2096 For generic frontend server, reverse the order of
2097 "toolkit-supplied / application-supplied" strings sent as implementationId,
2098 Name and Version. Also, remove the spaces around the slash. This brings
2099 the GFS in line with the behaviour of ZOOM-C on the client side.
2101 Add function ZOOM_scanset_display_term.
2103 yaz-client shows scan displayTerm if present.
2105 Utility yaz-iconv is now installed by default along with the man page
2108 Extend configure check for OpenSSL to use pkg-config where available (such
2111 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2112 server to specify uid/gid/mask for socket using the format
2113 unix:[user=uid,][group=gid,][umask=mask,]file=path
2114 If file= is omitted the existing format is assumed, e.g.
2116 in which case the mask is 0666 (rw for everybody).
2118 Major restructure of YAZ source. All source in libyaz is in src directory.
2119 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2120 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2122 Added man page for utility yaz-marcdump (used to be called marcdump).
2123 yaz-marcdump is installed by 'make install'.
2125 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2126 of incoming package failed.
2128 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2130 Change prototype of odr_perror: add const to message string.
2132 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2134 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2135 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2136 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2137 DNS lookup. There should not be any compatibility problems with this
2138 assuming that blocking=1 or 0 is used.
2140 Fix bad reference in UNIX comstack in function cs_addrstr.
2142 Fix for compilation on AIX.
2144 The generic front-end server (server/seshigh.c) now supports returning
2145 Init diagnostics to the client in User-information-field, in
2146 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2149 --- 2.0.4 2003/09/04
2151 Allow any CQL relation (not just all,any,exact,scr).
2153 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2154 that features the same UI.
2156 Implemented command update0 in YAZ client which is equivalent to
2157 update but uses old of Ext Update ASN.1.
2159 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2160 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2161 Previously no OID was used for this info.
2163 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2164 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2165 returns 'malformed search term' otherwise.
2167 SortResponse member resultCount now set to NULL in sort handler of
2170 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2173 Add three new utility functions for translating OIDs between various
2174 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2175 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2176 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2177 char *oid_to_dotstring(const int *oid, char *oidbuf);
2178 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2180 Reverted modifications for ES Update definition for z_IU0Update
2181 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2182 is back to YAZ 2.0.2.
2184 String value attributes for CCL parser.
2186 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2187 which their FirstSearch server returns in Init responses, sometimes
2188 carrying useful diagnostic information when Init fails. This has the
2189 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2190 "z39.50/oclcui.asn", where its definition is somewhat different from
2191 what OCLC document on their web-site, as required to interoperate with
2194 Support for anonymous authentication in yaz-client. Use the command
2197 * Fix the OID of the Index Data-local "admin" Extended Service from
2198 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2199 the 1000, which indicates a locally-defined OID, was a mistake.
2201 --- 2.0.3 2003/06/20
2203 Fix CCL directive @case handling so that it affects string match for
2204 both CCL keywords and qualifiers.
2206 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2207 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2208 Decoder has been updated with ASN.1 changes as listed in
2209 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2210 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2211 z_IUUpdate, remains unchanged.
2213 ZOOM_record_get may now return a record in a specific character set.
2214 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2215 "from" is the character set of record as returned by target. "to" is
2216 the character set to be returned. If omitted, "to" is UTF-8.
2218 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2220 New ODR utility, odr_getelement, which returns name of element for
2221 which encoding/decoding failed.
2223 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2224 in cases where a required element was omitted.
2226 Bug fix: some MARC8 sequences were not converted.
2228 New ZOOM option "step" which specifies number of records to be
2229 retrieved in one chunk. Used in conjunction with "start" and "count".
2231 SRW support for yaz-client. Use scheme http: to use it, e.g.
2234 yaz-client no longer does (un)intelligent character set conversions
2235 by default. Can be enabled with charset and marc_charset commands.
2237 xmalloc trace fix for 64-bit systems such as DEC alpha.
2239 Solaris 2.6 compile fix.
2241 New function, cql_strerror() translates SRW error codes, as returned
2242 by cql_transform_error(), into human-readable English strings. Used
2243 in yaz-client diagnostics when appropriate.
2245 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2246 converts it into a type-1 query which is sent to the server. This
2247 makes CQL available for use with all Z-servers, as opposed to the tiny
2248 minority that can handle CQL queries themselves.
2250 --- 2.0.2 2003/04/28
2252 New Debian package layout similar to the Redhat Package layout.
2254 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2255 and search result respectively.
2257 --- 2.0.1 2003/04/25
2259 Redhat package is now several packages: libyaz (runtime libraries),
2260 libyaz-devel (development and documentation, and yaz (utility programs).
2261 Package spec file by Morten Bogeskov.
2263 New member 'schema' in struct bend_fetch_rr which the name of requested
2264 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2265 handler MAY set this to reflect the schema of the returned record.
2267 New member 'display_term' in struct scan_entry. GFS now sets member entries
2268 and allocates scan entries to be filled by user scan handler. In previous
2269 version, entries member was allocated by the scan handler. That still works,
2270 but the GFS will ignore member display_term - assuming it was NOT set by
2271 the handler. The fact that the GFS now allocates the entries both allows
2272 for new members and makes a scan handler easier to write.
2274 Fix CQL lex buffer overflow.
2276 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2277 SRU default recordPacking is string.
2279 SRU protocol support for frontend server.
2281 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2283 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2285 Added scan for the ZOOM shell (zoomsh).
2289 * String Identifers for Schemas (Amendment 5).
2290 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2291 Old definition for schema
2292 Odr_oid *schema; /* OPT */
2297 Z_InternationalString *uri;
2298 #define Z_Schema_oid 1
2299 #define Z_Schema_uri 2
2302 * resultCount parameter to Sort Response (Amendment 1).
2303 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2305 Support for SRW 1.0 over HTTP. This is an optional feature and
2306 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2309 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2310 on the same port. SRW SearchRetrieveRequests are mapped
2311 to bend_init,bend_search,bend_fetch,bend_close.
2313 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2315 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2316 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2318 ZOOM connections are SRW based if schem http is used for hostname
2319 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2320 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2322 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2323 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2324 distance=n, order=true/false, relation=le, prox unit=word. If
2325 n is omitted, distance 1 is used.
2327 Fixed problem with C compiler include path in wrong order.
2329 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2330 on Solaris. Patch from Ko van der Sloot.
2332 New MARC decode API. All new functions operate on a yaz_marc_t
2333 handle. The most important new functions are: yaz_marc_create,
2334 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2335 decode and destroy respectively. Decoder can produce formats
2336 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2337 include/yaz/marcdisp.h.
2339 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2340 to UTF-8, UCS-32, wchar_t or Latin-1.
2342 * Prototypes for yaz_iconv_-functions moved to separate header
2343 include/yaz/yaz-iconv.h.
2345 Make a few private functions 'static' in unix.c. This prevents
2346 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2348 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2349 are set when Init Response is received.
2351 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2352 but returns diagnostic set as well.
2354 New function yaz_strerror which is a portable wrapper for
2355 strerror/strerror_r/GetLastMessage.
2357 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2358 is returned for MARC. If type is "oai", then OAI MARC is returned.
2360 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2363 --- 1.9.2 2002/11/26
2365 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2367 Fix bad race conditions on SIGTERM and terminate gracefully in
2370 Move retrieval (data1) module to Zebra since nobody seems to be
2373 Add GRS-1 render for ZOOM using same format as yaz-client.
2375 --- 1.9.1 2002/10/05
2377 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2379 Fix broken ESpec handling in data1 module.
2381 SGML reader parses comments and makes them part of the data1 tree.
2383 Added several type casts so that YAZ compiles as C++ code.
2385 ZOOM didn't handle PDU encoding failures properly.
2387 Added more Bib-1 diagnostics (approved extensions).
2389 GNU configure: better check for iconv.
2391 More portable use of accept, getpeername. Check for socklen_t. Use
2392 int/size_t if socklen_t is not defined.
2396 PQF parser rejects bad queries - including those with extra
2397 characters in them. PQF parser used to silently ignore that.
2398 Cleaner API for PQF added, which allows you to get detailed
2399 error information for bad queries (see yaz/pquery.h).
2401 Fixed bug in ZOOM_record_get for type "database".
2403 Implemented mini iconv library supporting conversions between
2404 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2406 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2408 --- 1.8.9 2002/08/20
2410 Fixed ZOOM C record cache so that preferredRecordSyntax and
2411 elementSetName is used to check for already fetched records.
2413 --- 1.8.8 2002/08/02
2415 Added three members in bend_initrequest structure to facilitate
2416 character set negotiation.
2418 Fixed a bug in frontend server that could cause indefinite
2419 loops under rare conditions.
2421 Revised character set utilities (charneg.h) so that encoding
2422 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2424 For PQF, directive @term <type> sets term type for Scan/Search.
2425 Here <type> is general, string, numeric, null. The term type
2426 is inherited - just like @attr.
2428 New call odr_set_charset that sets character set conversion for
2429 international-strings on a ODR stream. Prototype is:
2430 int odr_set_charset(ODR o, const char *to, const char *from);
2431 The InternationalString is still represented as C string in YAZ
2432 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2433 won't). On the protocol level, you can use any encoding.
2435 Support for UNIX sockets in ZOOM.
2437 Solaris recv sometimes returns errno == ENOENT. It is treated as
2438 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2440 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2441 both client and server. Code by Morten Bogeskov.
2443 --- 1.8.7 2002/05/22
2445 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2446 that they can be used directly from Visual Basic. You must recompile
2447 your windows APP if you're using ZOOM.
2449 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2450 Commands "lang" and "charset" sets language and character set respectively.
2451 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2452 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2454 Attributes from multiple CCL fields may be OR'ed rather than merged
2455 using directive "@field or". Fields are still merged by default -
2456 equivalent to "@field merge".
2458 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2461 Fixed bug in zget for parameter ExtendedServicesResponse.
2465 --- 1.8.6 2002/03/25
2467 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2469 Client displays USR.1:SearchResult-1 (hits per term).
2471 Additional Search Info for search in Generic Frontend Server.
2473 Fixed CCL parsing of "field=s".
2475 WIN32 installer - using the excellent NSIS software from nullsoft.
2477 Fixed CCL parsing of "field = - <number>".
2479 Added function yaz_marc_decode that decodes MARC for line mode
2480 display or XML (similar to that used by JZKit).
2482 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2483 Z39.50. But ISO/ILL was, however.
2485 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2486 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

2491 --- 1.8.5 2002/02/03
2493 New YAZ client features: Command completion and new commands:
2494 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2495 Code provided by Jacob Poulsen.
2497 New call oid_trav, that visits all registered OIDs via callback.
2499 Function ZOOM_record_get now returns const char pointer rather than
2500 void pointer. It saves a lot of type casts.
2502 For YAZ client, command "auth" now allows you to set authentication
2503 in IdPass style. It is enabled when three tokens are given - order
2504 is user, group and password.
2506 Fix memory leaks in MARC record handling for ZOOM.
2508 New option for YAZ client, -k <kilobytes> that sets
2509 maximum record size. Similar to -k option for generic frontend
2510 server and yaz-ztest.
2512 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2514 Prefix query parser reports "fail" when bad attribute set is given.
2516 Fix in MARC decoder. Proximity logging. Fix for attribute set
2517 in scan handler for server. Patches by Shigeru Ishida.
2519 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2522 Configure option --with-openssl=<dir> now works when a directory is
2523 specified. Patch provided by Morten Bogeskov.
2525 New option for YAZ client, -u <auth>, that sets authentication.
2527 ZOOM fix: error information was sometimes "missing", since error
2528 was cleared/reset too when it shouldn't.
2530 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2532 --- 1.8.4 2002/01/04
2534 Scan for ZOOM API. New object ZOOM_scanset. New functions
2535 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2536 ZOOM_scanset_destroy.
2538 New ZOOM function, ZOOM_connection_last_event, that returns type
2539 of last event (such as "receive data", "send data", "apdu received",
2542 New ZOOM option, schema, that specifies schema for retrieval.
2544 New CCL feature. Qualifiers can be aliases for one or more
2545 other qualifiers (if more than one is given, OR is used).
2547 ZOOM uses named result sets if target supports it.
2549 Two new YAZ client commands: . (dot, which sources a script of YAZ
2550 client commands), and ! (to execute shell command.). Implemented
2553 Working on Debian packages.
2555 --- 1.8.3 2001/11/19
2557 YAZ client enables named result sets only if target supports it.
2559 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2561 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2562 with key="host" to get same result.
2564 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2565 Function Z3950_resultset_record(s) returns references to records
2566 "owned" by resultset. To become owner use Z3950_record_clone.
2568 Function z_ext_record handles Extended Services. Thanks to
2571 --- 1.8.2 2001/11/12
2573 CCL Parser fix: ignore token comma when dealing with and-lists.
2575 Documentation updates for COMSTACK.
2577 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2578 Changed prototype Z3950_records. For some functions, int parameters
2579 were changed to size_t.
2581 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2584 New MARC decode/display function, marc_display_exl, which properly rejects
2585 non-ISO2709 records. YAZ client uses it.
2587 --- 1.8.1 2001/10/29
2589 Fix bug: local attribute set wasn't set correctly in PQF strings.
2593 * Old Z39.50 codecs no longer supported.
2595 Added ZOOM C binding. See http://zoom.z3950.org/
2597 Renamed states for COMSTACKs to avoid confusion with events.
2599 Implemented cs_look and proper cs_rcvconnect.
2601 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2603 Configure detects POSIX threads on OpenBSD.
2605 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2606 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2608 When error is returned from present handler, non-surrogate diagnostic
2609 is returned in present response (and fetch handler is no longer called).
2611 * Minor adjustments to pquery parser (PQF). Token characters may be
2612 escaped by using backslash (C-style).
2614 PQF parser allows string attribute values to be specified. For @attr,
2615 non-numeric characters after the equal-sign are treated as strings
2616 (e.g. @attr 9=title).
2618 CCL trunction character may be defined (@truncation in file)
2620 * function zget_ExtendedServicesRequest sets waitAction to
2621 waitIfPossible (was wait).
2623 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2626 CCL operator names may be set in field definition files (CCL_bibset).
2627 See ccl/bib1 for an example.
2629 Fixes in ASN.1 compiler for C++ compatibility.
2631 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2632 and "op_or" to avoid conflict with C++.
2634 Fixed problem with GNU readline detection on Redhat 7.0.
2636 Added step-size for Scan backend handler.
2638 Fixed bug that made the frontend server crash when no attribute
2639 set was specified for scan.
2641 Front-end server automatically switches to original working directory
2642 when installed as an NT service. Previously -w had to be specified to
2645 Added extended attributes for retrieval module (data1), so that data1
2646 records carry d1_readXML/SGML attributes. d1_read also supports
2647 null-data rules ( <tag/>)
2649 On UNIX when POSIX threads are available, a separate library libyazthread
2650 is created. Programmers should link with that library and the yaz library
2651 when using threads. The reason for the split was that some applications
2652 on Linux, such as Apache, doesn't work well when using shared objects that
2655 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2656 (or any frontend server) in SSL mode by specifying ssl: followed by
2657 address. Only tested on UNIX.
2659 Added feature for CCL module. Virtual structure s=al or s=ol generates
2660 and-list and or-list respectively instead of phrase search.
2664 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2665 log_mask_str. This was done to avoid name conflicts with other libraries
2666 (such as other PHP extensions).
2668 Added raw OID member for preferred record syntax (request_format_raw)
2669 and returned record syntax (output_format_raw) for backend fetch method.
2671 Config file yaz-config now accepts options so that it returns specific
2672 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2674 Shared library support for UNIX using GNU libtool.
2676 * Modified backend interface. Request/Response struct's replaced by
2677 one read/write C struct. For example bend_fetchrequest and
2678 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2679 Every handler - even search has to be registered in bend_init
2680 handler. This means that the YAZ library no longer refers to
2681 external functions and it makes it possible to make the whole
2682 thing a single DLL/SO.
2684 Added Segment handler for backend server.
2686 Added Zmbol/Zebra administrative functions to YAZ client.
2688 Threaded frontend server on UNIX (when POSIX Threads are available).
2689 Starting the server with option -T enables multi-threading.
2693 Added configure option --enable-comp/disable-comp to control use
2694 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2695 located in sub directory asn.
2697 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2698 in ${exec_prefix}/bin along with the other programs yaz-client and
2701 GNU automake used to maintain makefiles.
2703 Added several OID's.
2705 Changed retrieval module so that we can load records with no abstract
2706 syntax defined. Tagpaths in these records are fully composed of string
2709 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2713 On UNIX, the generated makefile now supports a proper 'make install'.
2714 The prefix can be set via GNU configure to set the install location
2715 (default is /usr/local).
2717 * YAZ programs client and ztest were renamed to yaz-client and
2718 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2719 locations, such as /usr/bin,/usr/local/bin,etc.
2721 * YAZ Header files were moved from include to include/yaz. YAZ Header
2722 files are referred to as include <yaz/log.h> rather than <log.h>.
2723 The YAZ include path (-I ..) is therefore the same as before. Programmers
2724 should update their #include statements or use -Ipath/include/yaz
2725 instead. The main motivation for doing this change is that YAZ header files
2726 can be installed in "standard" locations /usr/include,/usr/local/include
2727 without introducing conflicts, since ALL YAZ header files are stored
2728 in subdirectory yaz (under /usr/include for example).
2730 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2731 rather than project/workspace files. We switched because project files
2732 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2735 Changed name of logging function, logf, to yaz_log, to prevent name
2736 clash with some math-log functions. The YAZ header log.h defines logf
2737 to yaz_log (#define) so there should be no incompatibilities by this
2740 Added bend_start/bend_stop handlers for server. These handler are
2741 called on start/stop of server. For windows they are called whenever
2742 a service is started/stopped.
2744 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2745 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2746 in util/yc.tcl. The auto-generated C code structures are, in a few
2747 cases, incompatible with the old decoders. There are differences in the
2748 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2749 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2750 The preprocessor variable ASN_COMPILED is defined when the compiled
2751 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2752 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2753 wish to use the old encoders/decoders you can specify --disable-yc
2756 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2757 version so that it supports both new - and old version of DB Update
2759 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2760 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2761 change. The name parameter can be set to 0 in which no name is specified
2762 for the construction. The macros odr_implicit and odr_explicit sets name
2763 parameter to zero for the construction involved. New macros
2764 odr_implicit_tag and odr_explicit_tag are similar to the others,
2765 except that a name parameter is added. For programmers' that don't use
2766 ODR they probably only need to change the call to z_APDU and z_External.
2768 Added access control facility by interfacing the TCP wrapper library.
2769 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2770 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2771 name of the daemon and enables the access control as specified in
2772 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2774 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2775 den Dool <H.M.vdnDool@kub.nl>.
2777 Added reference ID parameter to most functions in server API - refer
2778 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2780 Changed name of ccl library to libccl.a (was ccl.a).
2782 Fixed bug in decoder for Explain (Category TargetInfo).
2784 Added support for GNU readline in client. Thanks to Jacob Poulsen
2785 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2787 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2788 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2789 IMPLEMENTATION! This change was made to the development version before
2790 the ZIG decided to retract the amendment. If any users MUST be
2791 compatible with the original Update definition, PLEASE CONTACT US, and
2792 we will include a separate definition corresponding to the old Update
2793 ES. Note that because of the change to the ASN.1 of the
2794 TaskPackageRecordStructure we cannot define a single structure that
2795 will support both versions.
2797 * Added const modifier to buffer parameter for some ODR/BER encoding
2798 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2799 completeWAIS, odr_dumpBER.
2801 Fixed bug in client.c which caused a crash when a scanResponse didn't
2802 contain positionOfTerm.
2804 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2805 * will cause an error in a client if a non-YAZ target sends both a
2806 * list of Scan entries and non-surrogate diagnostics.
2808 Retrieval module enhancements. Tag sets may be typed in the reference
2809 to it. From the .abs-file the "tagset" directive takes a third optional
2810 integer type for the tag set referenced. From a .tag-file the "include"
2811 directive takes a third optional type as well. The old "type" directive
2812 in the tag set itself is still recognized but acts as the default type
2815 Backend interface change. Individual Scan terms returned from bend_scan
2816 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2817 in include/backend.h.
2819 Retrieval module enhancements. Multiple tag sets and attribute sets may
2820 be specified in abstract syntax specs. Revised the error/warning for
2821 logging messages reported by the retrieval module when reading the
2824 Object Identifier system (oid_..) changed. The API is backwards
2825 compatible but the oid-routines now allocates new OID's when needed.
2826 Raw OID's may be specified in oid_getvalbyname.
2828 YAZ now uses GNU configure to generate Makefile(s).
2830 * Minor changes in some of the member names of DeleteResultSetRequest and
2831 DeleteResultSetResponse. See include/proto.h.
2833 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2834 and added member 'languages' in TargetInfo (which was missing).
2836 Changed the way attribute sets are handled in the retrieval
2837 module. These are now cached, just like the abstract syntaxes
2840 Changed YAZ so that it links with compiled ASN.1.
2842 Added Explain-schema definitions and mapping routines. The following
2843 Explain categories have been implemented: AttributeDetails,
2844 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2846 Fixed minor bug in Windows version of Server Library.
2848 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2850 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2852 Added EXTERNAL: UNIverse Resource Report (non-standard).
2854 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2855 ENUMERATED and SET OF.
2857 * Added 'const' to some of the char pointer arguments for the
2858 functions, data1_read_node, data1_getelementbytagname,
2859 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2862 Fixed bug in data1_insert_taggeddata - the last_child member of
2863 parent wasn't initialised.
2865 * Changed data1_read_record and data1_read_node so that the supplied
2866 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2867 doesn't refer to any parts of the "SGML"-buffer.
2869 Fixed bug in server library (Windows version of statserv_remove).
2871 * Changed code so that it compiles as C++. The type definition
2872 of Odr_fun which is a member of Odr_arm was changed. The result is,
2873 that an explicit typecast is needed for the fun pointer when
2874 using Odr_arm - as in:
2875 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2877 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2879 Implemented the new structured date and time definition as approved
2880 by the ZIG. Added schemaId element to the specificTag in Espec-1
2881 (also approved at the last ZIG). Thanks to RVDM.
2883 Added some Object identifiers (RVDM).
2885 Changed the Update Extended Service (RVDM).
2887 Added command "refid" to client which specifies referenceId for
2888 the following requests.
2890 Implemented extended service handling for server. See ztest.c
2891 for an example as well as backend.h. New handlers are registerd
2892 in the Init handler.
2894 * Changed interface for sort in server.
2896 Added new members to statserv_options_block. It allows a server
2897 to read options from another source than just the command line. Thanks
2898 to Charles Woodfield.
2900 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2901 renamed to zboolean. Some C++ compilers complained about the name.
2903 Minor changes to gils.abs. Added index 's' (sort) on title
2904 and date/time-last-modified.
2906 --- 1.4pl2 1998/1/30
2908 Fixed bug in server library regarding inetd mode (-i). This bug
2909 was introduced by release 1.4.
2911 --- 1.4pl1 1998/1/29
2913 Added sort facility in client and backend server interface.
2915 Fixed problem with dependencies in Makefile(s).
2917 Fixed bugs for encoders/decoders of extended services and
2920 Implemented sub-tree feature for schemas. Sub-trees are
2921 referenced in *.abs-files. See explain.abs for an example
2922 of the use of this feature.
2924 Modified bib1.att; local attributes for ANY didn't include
2925 ANY itself (only affects use of the retrieval module).
2927 Fixed bug in plain SGML reader in function data1_read_node:
2928 tags with prefix "var" was incorrectly interpreted as variants.
2930 Added feature "sub-schemas" to enable references to - and definitions
2931 of - group of elements.
2933 * Removed member parent from type data1_element (in data1.h).
2935 Implemented function odr_nullval() that returns the value of
2938 * Removed member num_children from data1_node (in data1.h).
2940 Made NT service interface part of the server library. The
2941 function statserv_main uses the NT service when required and
2942 calls the statserv_start / statserv_close routines.
2944 Routine zget_SearchRequest and zget_PresentRequest fills
2945 resultSetName/Id member with "default" instead of "Default".
2947 Fixed memory leak in server. Request queue member wasn't freed.
2949 Fixed nmem_exit so that memory is freed.
2953 Revised the CCL parser utility to be thread safe.
2955 Added function, oid_ent_to_oid, to replace the function
2956 oid_getoidbyent, which is not thread safe.
2958 * Added nmem_init and nmem_exit to initialize and release
2959 NMEM resources. Function nmem_init should be called once in the
2960 initial thread before NMEM/ODR is used. statserv.c and client.c
2961 have been changed accordingly. The change was necessary to make
2962 NMEM thread safe. The NMEM memory pool is shared amongst threads
2963 in a process. Unix-based applications will still work fine without
2966 Added NT Services interface for the the Z39.50 (statserv) Server.
2967 Refer to the ztest.c source on the usage.
2969 Windows 95/NT port using MSVC5.0. Project files are included in the
2972 * Defined new 'global' handle for the retrieval (data1) system. The
2973 new handled, data1_handle, describes the state of the data1 system.
2974 This handle is passed as first argument to virtually all
2975 data1 related routines. The functions data1_create and data1_destroy
2976 creates and destroys a data1 handle respectively.
2978 Added ODR encode stream member to all backend request structures
2979 init, search, scan etc. This stream should be used to allocate all
2980 memory used for the response when thread safe operation is needed.
2982 Changed the comstack utility, cs_addstr, to be thread safe. The
2983 returned hostname string returned by the function is now part the
2986 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2987 function. The cs_straddr takes a COMSTACK handle as argument, so this
2988 function must be used after cs_create and before bind/connect.
2989 This function is thread safe.
2991 Moved test server to 'ztest' directory - generic server code still
2992 in 'server' directory.
2994 Made prefix query (pquery.c) utility thread safe.
2996 Added new function modifier YAZ_EXPORT to 'export' public DLL
2997 functions when using windows (see include/yconfig.h).
2999 Added definitions to the OID database (util/oid.c) (RVDM).
3001 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3003 Added call to ccl_rpn_delete in client program.
3005 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3006 release of RPN structure.
3008 Added support for C++, headers uses extern "C" for public definitions.
3009 With input from RVDM.
3011 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3012 Thanks to Ronald van der Meer (RVDM).
3014 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3016 Added support for private extensions to the OID database
3017 (oid_setprivateoids()). Thanks to RVDM.
3019 Added optional, physical ANY (key replication)
3021 Fixed null-reference problem in GRS-1 output filter.
3023 Proximity operator added to Prefix Query Format (PQF).
3025 In test client command "base" accepts multiple databases.
3027 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3031 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3033 Smallish bug-fixes in the new encoders/decoders (explain).
3035 Bug fixed in DeleteRequest.
3037 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3039 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3041 Added SOIF syntax (using private OID for now) to retrieval module and client.
3043 Added Update extended service.
3045 Added SearchResult-1 additional info structure.
3047 Added optional CCL (ISO8777) interpreter as separate module. Available
3050 --- 1.2 1996/6/10 (1st anniversary release)
3052 Added Summary record syntax. Lightly tested.
3054 Added OPAC record syntax. Untested.
3056 Added ResourceReport service encoders/decoders. Untested.
3058 Fixed bug in z_Unit - wrong tagging on unitSystem.
3060 Fixed bug in the DiagRecs decoder.
3062 Added options for max PDU size and session timeout to frontend-server.
3064 Added documentation of query-language parsers and other supporting utilities.
3066 [frontend-server] Added Attribute set to the bend_scanrequest API.
3068 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3069 surrogate diagnostics were generated.
3071 [retrieval] Allow multiple local values for attribute.
3073 [retrieval] Allow multiple attributes per element in .abs files. index type.
3075 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3077 --- 1.1pl2 1996/4/10
3079 Minor changes, mostly specific to Zebra's requirements (retrieval)
3083 Repaired bug in frontend server when running multiple listening
3084 endpoints in dynamic mode.
3086 z_External() now won't break if a known, ASN.1 value comes encapsulated
3087 in an octet-string. The value will pass through unmodified in an Odr_oct.
3089 Added a bit of code to the demo client to decode & display
3090 ASN.1-structured records represented in the octet-aligned branch of
3091 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3093 Added z_ext_getentbyref() to the ASN module. Doc updated.
3095 * Completed the SCAN definition in the ASN module. This may break SCAN
3096 code based on older YAZ-versions at compile-time. The fix is easy -
3099 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3100 under the SCAN definition. Remember to initialize this, server-people.
3102 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3103 that this does not extend to ODR and ASN.
3105 Comstack allows insertion of established socket (primarily for
3106 inetd-operation of servers). Doc updated.
3108 Front-end server can now start from the inetd in TCP mode. Doc
3111 --- 1.0pl4 1996/1/24
3115 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3116 the rank and record number.
3118 Adjustments to the frontend server.
3120 Fixed diagnostic BER dumper. It ignored the file argument.
3124 Various changes to retrieval module.
3126 Changed the union discriminators of the protocol files from enums to
3127 ints paired with #defines.
3129 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3132 *Changed operator in the RPN structure to 'roperator', again to avoid a
3135 Fixed problems in Explain decoders/encoders.
3137 --- 1.0pl2 1995/12/6
3139 Memory bug in log module fixed.
3141 --- 1.0pl1 1995/12/5
3143 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3145 Bug in Explain DatabaseInfo module fixed.
3147 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3151 The shift to v1.0 signals that we now consider the *core* functionality
3152 of YAZ reasonably stable (the core being more or less equivalent to
3153 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3154 tested (Explain not at all - though that will happen soonish).
3156 Minor changes to code to support Windows port.
3158 Various minor changes after we're getting to use GRS-1 & co. more.
3160 Added Espec-1 format.
3162 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3163 of the protocol and it cannot be selected when encoding (maps into 'string'
3164 when decoding). Needed to talk to some servers.
3166 Demo client can request simple element set names.
3168 Added Diagnostic Format encoders/decoders.
3170 Added simple Close handling to frontend server (no hooks for resource
3171 reporting yet), and demonstration client.
3173 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3175 --- 1.0b3 1995/08/24
3177 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3178 handled incorrectly when records were requested in the searchResponse. This
3179 will only affect you if you use the frontend-server.
3181 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3182 Test-client will ask for and print GRS1. Ztest will return dummy records
3185 Added Explain encoders/decoders to the service-level API. Untested.
3187 Added Extended Services: Item Order encoders and decoders to the Service-
3188 level API. Untested. We could use a recent copy of the pertinent bits
3189 of the ILL protocol to add those bits.
3191 Added diagnostic format 1 encoders/decoders to the service-level API.
3194 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3195 odr_cons.c, which causes a more correct output.
3197 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3198 was always set to 0 when no records were requested in the searchRequest.
3200 * Added better external-handling. This shouldn't harm old code that
3201 *encodes* externals. It can break code that looks for a
3202 'single-ASN1-type' representation, since those types that are known
3203 are now decoded immediately. Look at the SUTRS sample code in
3204 seshigh.c and client.c. Documentation updated.
3206 Handling of structured records in bend_fetchresponse. Length -1 marks
3207 structured record, type is deduced from format field.
3209 --- 1.0b2 1995/06/27
3210 Fairly quick maintenance release to add SUTRS support.
3212 Fixed handling of SUTRS records in the demonstration client.
3214 * Added format field to the bend_fetchrequest and bend_fetchresponce
3215 structures of the backend API (frontend server). When the record is
3216 returned, the value of the format field is mapped to an OID. The
3217 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3218 of the record. The special value VAL_NONE in the bend_request means
3219 that no specific format was requested by the client. Documentation
3220 updated accordingly. Test server (ztest) will return a fixed dummy
3221 SUTRS record if your client requests SUTRS.
3223 Documentation updated accordingly.
3225 You can now set external libraries and RANLIB support in the top-level
3229 First public release.
