3 New function for daemon utility, yaz_daemon_stop .
5 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
9 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
10 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
14 YAZ daemon utility relays SIGUSR1 to child process.
16 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
17 would result in en empty database list - which in turn would result in
18 encoding failure for search.
20 Fix reading beyond string in yaz_sort_spec.
24 Add two new SRU diagnostics:
25 236: Access to specified database denied
26 1015: Init/AC: Maximum number of simultaneous sessions for Userid
28 Document the very useful ZOOM-C option "apdulog".
30 CQL to RPN: term may be passed through verbatim. This is enabled with
31 truncation.cql . The assumption being that the term is already CQL.
35 record_conv: leader spec may be given for marc element.
36 The leader spec is given as attribute leaderspec for element marc.
37 For example to convert a MARC21 record from MARC-8 to UTF-8:
38 <marc inputformat="marc" outputformat="marc"
39 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
41 record_conv: allow user-XSLT params. For example:
42 <xslt stylesheet="MARC21slim2DC.xsl">
43 <param name="myparameter" value="myvalue"/>
44 <param name="otherparameter" value="othervalue"/>
47 record_conv: fix error handling for missing marc charsets.
49 CQL: fix extra terms in wrong order.
53 record_conv: modify new API for conversion types. The conversion types
54 may be passed in new functions yaz_record_conv_configure_t and
55 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
57 Avoid mixed statement/variable declare; fixes compilation with Visual
62 Add non-standard SRU diagnostic: 235: "Database does not exist".
63 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
64 Update SRU to Bib-1 diagnostic maps accordingly.
66 CCL: add two new diagnostics for unsupported masking. The new
67 diagnostics are: "Embedded truncation not supported" and
68 "Single charcacter mask not supported".
72 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
76 Build YAZ for Ubuntu Oneiric.
78 CCL: allow parantheses for proximity operands. For example CCL query
79 (a) % (b) is now allowed.
81 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
82 marked dead, rather then being destroyed. If not, the session memory is
83 being free'd before the search/scan handler is finished. Also destroy
84 'request' memory in request_release rather than in various places,
85 which resulted in leaks from time to time.
89 cql_sortby_to_sortkeys: honor sort prefix.
91 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
92 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
93 The rpn2cql family of functions now always returns quoted CQL terms.
95 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
99 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
100 sequence is treated as one. For example, &&a=b&&&c& is identical to
103 --- 4.2.22 2011/12/05
105 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
106 APDUs for a connection to a WRBUF.
108 --- 4.2.21 2011/11/23
110 Fix cql_sortby_to_sortkeys. Completely broken before.
112 Make CCL's @truncation work again.
114 --- 4.2.20 2011/11/09
116 New ZOOM connection setting: tproxy. It's like proxy, but does not
117 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
118 to set resolved address + port for a connection outside ZOOM itself.
120 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
122 --- 4.2.19 2011/11/07
124 Fix uninitialized variable in Solr spell support (could cause SEGV
125 for SRU response decoding).
127 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
128 back-end's addinfo through into the ZOOM response addinfo.
130 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
131 they are separated by a colon and a space rather than simply
134 --- 4.2.18 2011/10/28
136 Add support for Solr spell-checking/suggestions through ZOOM.
137 If a Solr target has been configured correctly for spelling-checking
138 and suggestions, these will now be returned on the ResultSet option
139 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
141 --- 4.2.17 2011/09/28
143 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
144 with a flag whether to substitute escape sequences or not.
146 --- 4.2.16 2011/09/22
148 Fix nmem_strsplit_escape to substitute escape char properly.
150 New option for zoomsh -e , which makes it abort on first error and
151 return process exit code to indicate success/failure.
153 YAZ options utility supports special option -- which makes all it treat
154 all following arguments as non-options.
156 --- 4.2.15 2011/09/16
158 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
159 searched if absolute filename is given.
161 Fix conv_xslt() error-reporting when stylesheet is not found.
162 (The value of fullpath is meaningless in this situation.)
164 --- 4.2.14 2011/09/07
166 Fix problem in CQL sort node creation: un-initialized memory.
168 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
169 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
170 CQL sortby depending on whether Type-1 or CQL is actually sent to the
173 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
174 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
176 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
177 will make it possible to use both single-character mask (#) and wildcard (?)
178 in CCL . Throw diagnostic for left truncation because that is not supported
181 --- 4.2.13 2011/09/01
183 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
184 cases using escapes (\-sequences) and masking.
186 PQF parse fix: A trailing backslash followed by end-of-string (\0)
187 would result in a read one byte beyond string.
189 rpn2ccl may use Z39.50 masking for terms (t=z).
191 ICU check fix. Don't include library -lCrun on Solaris, unless present.
193 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
194 not --cppflags (which seeems like an error in icu-config).
196 --- 4.2.12 2011/08/27 RPM package only
198 cql2ccl: fix conversion of terms: operator characters were not
201 --- 4.2.11 2011/08/25 RPM package only
203 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
204 CCL parser will map both # and ? to their regular expression
205 quivalents (. and .*).
207 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
208 of reserved CQL characters.
210 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
211 is, so that they are passed through.
213 --- 4.2.10 2011/08/24
215 ZOOM SRU mode: more aggressive re-connect.
217 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
218 made available as a utility function, declared in <yaz/logrpn.h>
220 rpn2cql_structure() supports proximity nodes (except that the Type-1
221 proximity node's "exclusion" binary is ignored, as there is no way to
222 express that in CQL). Fixes bug #4564.
226 Fix SEGV that could occur if set command of zoomsh was given without
227 value (2nd argument).
229 Fix SEGV that could occur if unsupported transport was given for
230 COMSTACK - say https (when SSL was unavailable).
232 Build yaz-url on Windows too.
236 New utility to get web content. Header is url.h. A command line tool
237 yaz-url is part of the distribution and packages.
239 Fixes for SSL COMSTACK (when gnutls is in use).
241 New functions yaz_base64{encode,decode}. Header is base64.h.
245 ZOOM C includes HTTP response buffer as additional info if it fails
246 to decode the SRU response.
248 Make wrbuf_json_puts available.
252 zoom: throw diagnostic for invalid value for option "sru". Before a
253 bad SRU request was sent.
255 Adding new utility wrbuf_vp_puts.
257 Add cclxmlconfig.obj to win/makefile. It was missing completely.
261 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
262 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
263 redirect was used at the same time.
265 MARC line mode decoding: be less picky about length given - first
266 5 digits of header that is.
268 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
270 Changes to decoding of SRU records: a record with recordPacking=xml is
271 modified with a new root element <yaz_record> if the recordData contains
272 multiple children elements. This is to make the record XML parseable
275 RPN to SOLR conversion: encode special characters.
277 Generic Frontend Server: fix uinitialized member, stepSize.
281 Fix a bug in SRU decoding of records.. The database records stored
282 had un-initialized memory, but it would only be seen with yaz_record_render
283 and type_spec="ext" .
285 Fix a bug in ccl_qual_dup introduced in 4.2.3.
289 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
293 Add new utilities to convert from CQL to CCL . These utilities have
294 prefix cql_to_ccl defined in cql.h.
296 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
297 lead to memory heap corruptions when ICU utilities were in use.
301 Make compilation work without Libxml2.
303 yaz-client: remove redundant blanks in display of searchResult-1 term
308 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
309 resulting CQL node (tree) in a new node CQL_NODE_SORT.
311 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
312 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
313 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
314 Note that the CQL sortby spec is only converted when the GFS is already
315 converting from CQL to RPN (cql2rpn element).
317 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
318 specify whether to collapse delimitors or not. The existing nmem_strsplit
319 do collapse (collapse parameter = 1).
321 Windows installer: For NSIS, set InstallDir depending on x86/x64.
323 Rename internal func yaz_use_attribute_create. While non-static, this
324 function is not declared in a public header.
328 Add -lCrun when linking with ICU on Solaris.
330 More quicks character set conversions for OPAC records.
334 fix problem with record_render: records were converted (character set
335 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
339 SRU: add methods for handling DADS SRU-proxy facets.
341 Separate OPAC record character set for ZOOM_record. yaz_record_render
342 allows a character set given as charset=from/opacfrom,to where 'from' is
343 the character set of a bibliographic record, 'opacfrom' is character set
344 of OPAC record and 'to' is the target character set.
348 yaz-client: show may XML format records. Command show followed by 'format'
349 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
352 src/stemmer.c: Avoid using unnamed union. It is not supported by some
355 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
358 Update yaz.spec to operate on both SLES11 / Centos 5.5.
360 RPM: Release includes 'indexdata' name. Use indexdata in release name so
361 this package can be distinguished from other vendors.
363 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
364 as determined by configure
366 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
368 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
369 returns no error and no record, the present request is considered
370 partial (only a subset of the records could be returned by backend), and
371 so it is appropriate to set Present Status to partial-4.
375 Move yaz-config man pages to section 1.
377 More documentation about SOLR.
379 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
380 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
381 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
382 peers on some Linux systems. However, in general that does not work
383 so YAZ can not rely on that to work. Debian changed behavior in this
384 respect from Debian lenny to Debian squeeze (still testing as of Oct
386 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
388 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
392 Fix yaz-config output: echo_source not set correctly by configure.
396 SOLR WebService support for yaz-client and ZOOM.
398 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
400 --- 4.0.12 2010/08/17
402 Z39.50 facet support. Facet specifications are passed for search in
403 other-information with ASN.1 as defined in facet.asn and OID
404 .10.1000.81.5 . Facets are expressed as an Attribute list as known
405 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
406 3 is limit (number of entries to get in response). yaz-ztest returns
407 dummy facets if a client asks for them.
409 --- 4.0.11 2010/07/09
411 CCL fixes: bug 2895 and bug 3539.
413 GR1-display: add comma in display - was removed by mistake in
416 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
418 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
420 --- 4.0.10 2010/06/18
422 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
423 result set from a connection. The result set will be on its own
424 thereafter; no operations on it will perform retrievals from a target.
425 Only cached copies are returned.
427 ZOOM C:fix case for HTTP servers responding with Connection:close.
428 Ensure that if there is a current task it is resumed (like fetching
429 more records in a result set) . Bug #3484.
431 PQF parser: use odr_atoi for Odr_int (not atoi)
433 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
434 values that contain any non-digits are treated as string attributes
435 (previously decoding only checked for leading character ([0-9]). PQF
436 encoding: attribute string values are not surrounded by double-quotes.
440 New utility for managing threads - thread_create.h.
442 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
443 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
444 but YAZ' implementation do.
446 Fixes for yaz_cond-functions on Windows 7.
448 DLL export more symbols.
450 zoomsh: show record do NOT render opac.
452 Remove *.la files from Debian and RPM packages.
456 Debian package libyaz-dev depends on libgnutls-dev again (was
457 removed in YAZ 4.0.6, but due to Libtool it is still needed
458 even though yaz-config do not list libgnutls libs).
460 ZOOM: Use only one WRBUF for returning string results for
461 ZOOM_resultset. Reduces memory usage for ZOOM in general.
463 ZOOM: ZOOM_connection do not use a shared pointer to
464 ZOOM_resultset after ZOOM_resultset is destructed by
465 user. Reverts to YAZ 4.0.4 behavior.
469 record-conv: fix problem with at least one XSL conversion -
470 due to probably incorrect usage of XML XSL documents.
474 Fix yaz-config for static mode and the use of SSL (gnutls).
478 Forward decl timeval struct in mutex.h and gettimeofday.h.
480 yaz-config: fix 'static' mode linking.
484 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
485 are wrappers for pthreads or Windows. For Windows these are put in
486 a separate DLL: yaz_cond4.
488 libyaz.la (whole source) is compiled with thread. If thread support
489 is enabled enabled, all source of YAZ is compiled with treading support.
490 This allows core utilities such as yaz_log to use thread facilities.
491 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
492 thread utilities. This commit moves mutex utilities (mutex.c) from
493 libyaz_server.la to libyaz.la.
495 yaz-json-parse displays leading text until error.
499 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
500 patch from Giannis Kosmas.
502 SRU: no longer URL encode SRU database. The URL for an SRU server is
503 a URL and such is alreeady encoded - at least when given with leading
504 http:// or https://. This reverts behavior to YAZ 3.0.50.
506 Support for new MARC XML notation TurboMARC which like MARCXML is a
507 complete representation of MARC/ISO2709.. This one, however, is more
508 compact and allows for faster processing with XSLT. TurboMARC can be
509 used in the marcdisp.h API, from the yaz-marcdump utility and from
512 yaz-ztest can be configured - via the database - to perform certain
513 delays when it performs operations search, present and single record
514 fetch. This allows testers to make yaz-ztest act as a real or even slow
515 Z39.50 server. Refer to the yaz-ztest man pages for details.
519 wrbuf_destroy allows NULL WRBUF passed to it.
521 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
523 Add ZOOM_connection_close.
525 No fixed size buffers for ZOOM shell - bug #3257.
527 tstodr: make it work on s390 platform.
529 New icu iterator-functions. The new icu_iter-functions makes it possible
530 to use ICU chains from many threads.
532 yaz-client: better syntax check for show command.
536 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
539 New simple local-file XML include facility which allows file glob-patterns.
540 Refer to yaz/xml_include.h.
542 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
545 ZOOM_record_get supports new parameter "format" which makes it format XML
548 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
549 JSONText in ECMA-262) is JSONValue, not JSONObject.
553 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
554 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
556 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
557 POSIX/Unix builds .so with major version 4.
559 Remove old LOG_-defines from log.h. They have been obsolete and
560 undefined by default for the last 5 years.
562 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
564 GFS: Remove socket (int *fd) from search_rr handler. The socket
565 descriptor ptr is a facility that allowed a search handler to supply
566 a socket which would serve as a callback - when search was complete.
567 This facility has now been in use for years.
569 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
570 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
571 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
572 returns 'const char *' rather than 'char *. The returned string is
573 read-only and should not be modified by applications. COMSTACK cs_close is
574 now a void function - it no longer returns int. No applications check for
575 the value and the implementations has always returned 0.
577 ZOOM: use size_t for scan hit counts and str size. Functions
578 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
579 occ (hit count) and len (string length) are now of type size_t pointer
580 rather than int pointer. This is to be able to represent large hit counts
581 and to also just to use the proper type for string length (strlen result).
583 New JSON parser. Refer to include/yaz/json.h .
585 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
586 Used to be int in some cases. Many wrbuf_-functions used to return an int
587 indicating some length.. These return values were never used. And so they
590 ODR: odr_malloc, odr_total now takes size_t for size.
592 clone_z_type: fix leak; occurred for encoding failures.
594 --- 3.0.52 2009/12/03
596 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
597 bug was introduced in 3.0.51.
599 --- 3.0.51 2009/12/02
601 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
603 tcpip comstack: fix leak for getaddrinfo.
605 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
606 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
607 Decoding of SRU "path" database is performed by private function
608 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
609 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
611 yaz-client: honor base command for SRU. Change when database setting
612 is applied for SRU and ensure it is kept when a connection is reset.
613 Change also the way errors are displayed or SRU (decoding of packages).
615 --- 3.0.50 2009/11/02
617 Add support for extra request / response data for SRU codecs and GFS.
618 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
619 for extra data response buffer and length. For the GFS, both request
620 and response data (XML) is carried in extra_args and extra_response_data
621 for the search handler. Patch by Ko van der Sloot.
623 ZOOM: For queries that cannot be converted to the specified rpnCharset,
624 ZOOM now returns a diagnostic on the client-side ('invalid query' /
625 10010). This fixes bug #2113.
627 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
628 cmdfile included a 'quit' command that would result in a memory violation.
630 --- 3.0.49 2009/10/01
632 Make a number of functions defined in xmlquery.c static. These have
633 never been declared in a public header file (yaz/xmlquery.h) and was
634 made public by mistake.
636 Improve speed of character conversions (iconv utilities). This makes
637 conversions from MARC-8 faster.
639 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
640 unless type desired is "raw". This will prevent type "xml" from
641 returning ISO2709 .. Which obviously can not be XML parsed.
643 Fix memory leak in ZOOM that would occur if option apdulog was used
644 on a re-used connection.
646 Frontend server logs HTTP requests.
648 Frontend server now sends Z39.50 close when it times out (sesssion has
649 been idle for too long). Versions 2.0.30 and earlier also sent close.
650 But due to a mistake this was disabled in all versions after that, i.e.
651 the server would just close the socket immediately.
653 yaz-client emits a better message when receiving an unrecognised
654 userInformationField.
656 Skip zero-length subfields when decoding ISO2709. This rare case happens
657 if a record has two FS characters in a sequence. Without this patch
658 there would be a reference beyond char array in using_code_len fragments
661 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
663 --- 3.0.48 2009/08/28
665 The show command offered by the zoomsh command now takes a 3d optional
666 parameter type which is what is passed to ZOOM_record. If the type
667 argument is omitted, "render" is used.
669 RPN to CQL conv may use USE string attributes (bug #2978).
671 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
673 --- 3.0.47 2009/07/08
675 Function yaz_xml2query allows a diagnostic element in the PQF XML
676 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
677 code and additional info respectively.
679 The BER BOOLEAN is now the integral type Odr_bool which still happens
680 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
681 typedef'd to Odr_int. This is still an integral 'int', but it may be
682 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
683 ASN-1 compiler as well as programs has been updated to use the new types.
685 --- 3.0.46 2009/06/08
687 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
688 only the bibliographic record was rendered. For type=opac, an OPAC
689 record is only returned if it is present.
691 iconv: small fix for encoding of advancegreek.
693 yaz-client: avoid double display of SRU/SRW records (bug #2798).
695 yaz-client: option auto_reconnect=on really reconnects.
697 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
699 server: avoid null ptr ref for for yaz_poll errors.
701 build: fix RPM build for RHEL 5.3.
703 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
705 --- 3.0.45 2009/03/31
707 Fixed bug #2709: TCP connect returns Invalid argument.
709 Fixed compilation for mingw.
711 Honor charset for raw records (ZOOM_record_get).
713 Fixed use of errno for threaded mode that was seen on Solaris 10.
715 Fixed argument passing with blanks in value for Windows Service.
717 Disable YAZ' own log rotate by default (no 1 GB limit).
718 The variable l_max_size which specifies the log file limit is set to 0
719 (DISABLED): This is due to the fact that YAZ is most often deployed using
720 logrotate. Also YAZ can not perform log rotate because of unsufficient
721 permissions (setuid).
723 --- 3.0.44 2009/02/17
725 List supported encodings in man page for yaz-iconv.
727 Fixed missing SSL libs for --libs output
729 Re-established OID record syntax application-xml. Nobody should use it
730 but we don't want to change soname because of this symbol being absent.
732 --- 3.0.42 2009/02/02
734 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
736 Added member named_result_sets for init handler struct for the GFS. This
737 allows a server to disable named result sets.
739 Removed OID record syntax application-xml.
741 Added support for rule-based transliterator for ICU wrapper of YAZ.
743 Fixed bug #1902: yaz-icu XML output.
745 Make YAZ checks Emacs friendly.
747 BITSTRING value shows value. Bug #2346.
749 ISO2709 decoding: skip control characters from indicator data.
751 Omit sort key by default in yaz-icu's output.
753 Allow combined single char options (again) for YAZ' options function.
755 Utility yaz-marcdump got option to display YAZ version (-V).
757 Allow YAZ to use ICU 3.4.
759 Added new ICU test case which illustrates removal of diacritics.
761 --- 3.0.41 2008/12/29
763 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
765 --- 3.0.40 2008/12/29
767 For configure, using option --without-xml2 also disables Libxslt/Libexslt
770 Fixed bug #2352: yaz-marcdump crashes for certain record.
772 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
774 Added support for Danmarc2 to UTF-8 conversion.
776 Added support for ISO5426 to UTF-8 conversion.
778 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
779 implementation version.
781 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
783 --- 3.0.38 2008/11/10
785 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
786 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
788 ZOOM C now interprets databaseName option for ZOOM connection as path
791 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
793 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
795 Dummy Libxml2 types no longer defined in headers of YAZ'.
797 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
800 --- 3.0.36 2008/09/26
802 Various ODR chapter fixes.
804 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
806 Added missing source for Windows compilation, mutex.c.
808 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
810 For SRU connections in ZOOM all records up to "count" are now fetched.
812 Fixed crash in generic frontend server (and yaz-ztest) which occurred
813 in Windows due to bad error handling for Libxml2.
815 Added facility for sending arbitrary records (ASN.1 any) using
816 ZOOM C's Extended service update. Patch by Sam Reynolds.
818 New options for ZOOM C's connection, logapdu which makes ZOOM log
821 --- 3.0.34 2008/06/18
823 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
825 --- 3.0.32 2008/06/12
827 Fixed memory violation that could occur when decoding UTF-8. This bug
828 was only present in 3.0.30 of YAZ.
830 --- 3.0.30 2008/06/06
832 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
833 GNU TLS is used by default (if found).
835 yaz-ztest returns OPAC records if a client asks for OPAC.
837 Improved speed of MARC-8 encoding.
839 Added support for lossy and loss-less MARC-8 encoding.
841 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
843 Added new Windows Service wrapper (sc).
845 yaz-client's itemorder command may now send a file.
847 Fixed yaz-marcdump to allow the use of NS prefix for record element.
849 Added new function yaz_log_xml_errors.
851 Allow (but warn) unknown XML attributes in MARCXML parsing.
853 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
855 The UTF-8 to MARC-8 conversion now uses a different set of characters
856 for Greek symbols. Bug #2120.
858 --- 3.0.26 2008/02/21
860 Added yaz_daemon (daemon.h).
862 Fixed bug #2068: pkg-config trouble
864 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
866 --- 3.0.24 2008/01/28
868 Document --with-xml2 option.
870 Added OPAC XML XSD (etc/opacxml.xsd).
872 Allow glob mask for name attribute in retrieval element for the
873 generic frontend server's retrieval facility.
875 Changed yaz_poll_poll to return yaz_poll_except for all returned events
876 except POLLIN/POLLOUT.
878 Fixed error handling in cs_listen. Bug #2037.
880 --- 3.0.22 2008/01/20
882 Fixed version in yaz/yaz-version.h.
884 Fixed bug #2027: Crash when closing connection.
886 Changed configure so that ICU support is only enabled if only ICU
887 and Libxml2 is available (because the ICU chain is XML based).
889 --- 3.0.20 2008/01/15
891 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
892 is built. Only this DLL depends on the ICU runtime.
894 yaz-ziffy is no longer part of YAZ. It is distributed separately by
895 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
897 Changed license of CCL module to 'Revised BSD'. After consultation with
898 remaining members of the original EUROPAGATE consortium, we are re-issuing
899 the CCL module without a separate license. The software was developed by
900 Index Data as part of a research project. The special license was included
901 to help feed usage information back to the project consortium to support
902 project evaluation. At this time, the project consortium has long-since
903 disbanded, and the majority of the original principals have retired. At the
904 same time, we have significantly modified the software during the following
905 years, to the point where very practically no original code remains. To
906 simplify re-use of the software, we have contacted those members of the
907 consortium who could be reached, and agreed to re-issue the module as a
908 proper part of the YAZ package.
910 Tcl scripts uses /usr/bin/tclsh as preferred shell.
912 CQL closer to being version 1.2 compliant. CQL also allows free-form
913 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
916 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
917 bug could make Extended services handling crash in the ZOOM layer. This
918 bug was only present in YAZ 3.0.18.
920 --- 3.0.18 2007/12/19
922 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
925 yaz-marcdump reads and writes collection wrapped records.
927 Handle OPAC for record conversion module.
929 Fixes for ICU wrapper.
931 Allow ICU libs to be controlled with --with-icu .
933 --- 3.0.16 2007/11/12
935 Added yaz_poll which is a wrapper for select/poll. When poll is available
936 and non-buggy, it is used, by yaz_poll . This allows more than 1024
937 sockets to be in use.
939 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
940 functionality through an XML based configuration (ICU chain). This system
941 is useful for search facilities such as Pazpar2 and Zebra that needs to
942 perform tokenization of indexed material. The ICU code in a separate
943 library libyaz3_icu.a.
945 Added HTTP tunnel facility for COMSTACK, bug #1752.
946 This is a facility that allows a Web proxy, such as squid, to tunnel
947 Z39.50 traffic. This facility is "transparent" to must applications
948 using YAZ. It's enabled by using pseudo transport connect: followed by
949 the proxy address, followed by command, then follwed by he regular
950 "virtual" addresss. For example,
951 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
953 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
955 --- 3.0.14 2007/09/21
957 Fixed bad memory reference in ZOOM_record - cuased by member not being
958 initialized. This was a problem only in YAZ 3.0.12.
960 Fixed bug in conversion from MARC to XML: Non-XML characters in control
961 fields were not removed.
963 Changed the way C code is generated from codetables.xml. Made a MARC-8
964 conversion trie for each characterSet section rather than codeTable.
965 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
966 of codetables.xml from Larry Dixson, LOC. Bug #1464.
968 --- 3.0.12 2007/09/12
970 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
971 from ZOOM_record_error).
973 ZOOM C function ZOOM_record_get returns record schema for type="schema".
975 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
977 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
979 Better SRW-to-Bib-1 diagnostic mapping.
981 ZOOM C and yaz-client announces SRU version 1.2 by default.
983 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
986 Fixed in yaz_sru_decode to allow other version than 1.1.
988 --- 3.0.10 2007/08/22
990 Added support for SRU scan for ZOOM.
992 Added support for the use of the older versions or Extended Service
993 Update in ZOOM. To faciliate this, an option "updateVersion" may be
994 set to the version , 1=first, 2=second, 3=third. The third version is
995 what ZOOM C has used so far. And that, obviously, is the default.
997 Added support for CCL queries in Z39.50 queries sent to the GFS (and
998 therefore in Zebra and in SimpleServer-based applications). The new
999 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1000 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1001 which is passed into the back-end search callback function.
1003 Added support for HTTP Basic authentication in clients: the SRU/W
1004 codec encodes the username/password elements of the PDU structure
1005 appropriately, and these may be set using the "user" and "password"
1006 options in ZOOM-C applications (the same options that are used for
1007 Z39.50 authentication).
1009 --- 3.0.8 2007/06/25
1011 Fixed bug #1208: SSL appears to be broken in ZOOM.
1013 Fixed bug #1206: Libxml2 include path weirdness.
1015 Added oid_name_to_dotstring.
1017 Allow elementSetName to be specified for ZOOM C record update.
1019 Allow waitAction to be specified for ZOOM C based for Extended Services.
1021 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1022 syntax OID. Bug introduced in YAZ 3 series.
1024 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1026 --- 3.0.6 2007/06/06
1028 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1029 directory. yaz-client now reads commands from file given by option -f
1030 if specified; then tries to read .yazclientrc in current directory.
1031 Failing that, it reads .yazclientrc from user's home directory.
1033 Added support for correlationInfo Note and ID for Record Update via
1036 Added yaz-client command querycharset which specifies character set for
1037 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1038 (termListAndStartPoint).
1040 Charset ISO5428:1984 is an alias for ISO5428-1984.
1042 Implemented a way to perform scan in a result set using Z39.50. This
1043 is achieved by attaching the result set name in the characterInfo
1044 (type InternationalString) of OtherInformation in the Scan Request PDU.
1045 The result set is identified in the otherinformation by the new OID:
1046 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1047 This allows for scan in result set and faceted search . Zebra did some
1048 of this in the APT term using attribute type 8 and value being result
1049 set. Using the OtherInformation approach for this is cleaner and easier
1050 to work with in proxies and the like. This facility can be used in
1051 yaz-client using new command setscan which takes a result set as first
1052 argument, start position (APT) as second.
1054 Changed decoding of SRU XML packed records to deal with servers that
1055 have recordData with XML data with multiple root nodes. Also make
1056 comparison for recordPacking case insensitive. Again, one server
1057 returns "XML" where others return "xml".
1059 For SRU responses allow Content-Type application/xml as well as text/xml.
1061 --- 3.0.4 2007/05/21
1063 Fixed bug in character set conversion of BER strings. Bug introduced
1066 --- 3.0.2 2007/05/08
1068 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1070 For OID class, use oid_class consistently.
1072 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1075 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1076 character set for bibliographic information interchange". By Giannis Kosmas.
1078 Added documentation on new OID API.
1080 --- 3.0.0 2007/05/02
1082 Changes to generic frontend server interface: added new member
1083 'query_charset' for bend_initrequest structure. A backend init handler
1084 should set this member to its native character set for query terms.
1085 When defined, the frontend server logic will announce this character set
1086 to a client if the negotiationModel bit is set by the client. All server
1087 implementors are encouraged to specify this. If a backend server does not
1088 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1090 Added CCL utility to remove terms (stop words) from resulting RPN
1091 tree. This is handled by functions with prefix ccl_stop_words_ .
1093 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1094 terms in RPN queries.
1096 Clean-up the CCL API. Moved some internal structures from ccl.h to
1097 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1098 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1099 This is replaced by ccl_parser_find_str which takes a string instead.
1101 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1102 libyaz.la is the core of YAZ except the generic frontend server and
1103 does not depend on POSIX threads anymore. libyaz_server.la is the
1104 generic frontend server facilities and uses POSIX thread functionality
1105 if available. The libyaz.la no longer depends on POSIX threads because
1106 the number of global structures is limited. NMEM no longer re-uses blocks
1107 between threads ; it simply free's memory immediately but allocates in
1108 "large" chunks as usual. We don't expect any performance penalties
1109 because of this. The yaz_log system is still using a global log_level so
1110 caution must be taken when modifying it with yaz_log_init_.. +
1111 yaz_log_mask_str. This, however, should not cause any trouble because
1112 these functions are called during initialization of application code
1113 anyway. `yaz-config --libs server` returns libs for server applications;
1114 `yaz-config --libs` returns libs for non-server applications.
1116 New OID database - with public definitions in oid_db.h. Removed old OID
1117 database including the head oid.h and definitions such as enum oid_value
1118 and struct oident. The new OID database uses the same string names as
1119 before but the 'protocol' is gone. There are now only two representations
1120 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1121 converts from string to OID; functions with prefix yaz_oid_to_string
1122 converts the other way.
1124 Change to emit_term() in CQL-to-PQF query translation: when a term has
1125 the /regexp relation modifier, do not process it for leading and
1126 trailing "^" and "*", which have quite different meanings in regular
1129 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1130 write handlers no longer carries a 'last' parameter. This will make
1131 yaz_iconv flush "less" characters. A flush is performed by call to
1132 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1134 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1135 removed, because function yaz_query_to_wrbuf does the same.
1137 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1138 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1140 Deprecated MARC utility functions removed.
1142 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1145 Branch split: YAZ_2_1_55_branch
1147 --- 2.1.54 2007/03/16
1149 Fix to ZOOM-C so that transparent reconnection is properly handled on
1150 connections that are in asynchronous mode.
1152 Fixed compilation on OpenBSD 4.0.
1154 Large strings in GRS-1 records are now properly displayed in yaz-client.
1156 Added character conversion support for "advancegreek"; based on patch from
1159 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1160 sequence is met. Before the error was not set so it would be unknown.
1162 Adjust yaz-marcdump MARC reader so that it skips until record separator
1165 --- 2.1.52 2007/03/07
1167 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1168 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1169 fd_set structure used as a bitmask for the FDs to be selected on.
1171 Using ACX_PTHREAD macro to check for POSIX threads.
1173 Fixed have-vsnprintf check.
1175 --- 2.1.50 2007/02/23
1177 Fixes for configure on BSD. Bug #900.
1179 Added snprintf/vsnprintf wrappers for systems that don't have
1180 limits (heavens forbid).
1182 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1183 created before all previous tasks were completed and removed from the
1184 task queue, the new task could be removed by a mistake.
1186 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1188 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1190 Fixed bug #832: Problem with MARC/charset in yaz-client.
1192 Fixed bug #668: save command line history for yaz-client.
1194 Fixed bug #830: pkg-config support.
1196 --- 2.1.48 2007/01/23
1198 Extended ZOOM result set options with two options that may be read by
1199 a client: resultSetStatus and presentStatus with values as specified for
1201 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1203 Fixed bug #827: Using SSL fails on Debian etch.
1205 Fixed bug #826: Weird looking chars for set of MARC records.
1207 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1208 that is treated as an ItemOrder with itemRequest being an XML document
1209 external. The value of "doc" is the content.
1211 Extended the GFS search facility. New member of bend_search_rr
1212 'estimated_hit_count' signals that hits is known to be an estmate
1213 (higher or lower than real hit count). New member 'partial_resultset'
1214 signals that the search was partial (hit count is lower or equal than
1215 real hit count). For Z39.50, the information is stored in resultSetStatus
1216 member of SearchResponse APDU. For SRU, the information is signalled
1217 via SRU diagnostic 59: "Result set created with valid partial results
1220 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1222 --- 2.1.46 2007/01/13
1224 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1226 Added ZOOM_connection_peek_event.
1228 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1229 the following new functions:
1230 ZOOM_event_nonblock, ZOOM_connection_process,
1231 ZOOM_connection_get_{socket,mask,timeout},
1232 ZOOM_connection_fire_event_{timeout,socket}.
1233 The existing blocking event handler, ZOOM_event, is a wrapper for the
1234 + blocking ZOOM_event_sys_{poll,select}.
1236 Implemented function ccl_xml_config which parses XML version of CCL
1237 configuration (bug #798).
1239 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1241 Added timings utility (yaz/timing.h)
1243 --- 2.1.44 2007/01/03
1245 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1248 Fixed bug #779: Rotation of apdu.log fails.
1250 Fixed for character set conversions:
1251 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1252 Honor G1 set in MARC-8 decoding.
1254 --- 2.1.42 2006/12/17
1256 Fixed bug #775: char conversion does not handle Alternative UTF-8
1259 Implemented function yaz_marc_read_line which parses MARC line format
1260 records. There is a wealth of formats out there. So far, this function
1261 reads line records produced by yaz_marc_write_line.
1263 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1264 more generic and easier to remember(!) options: -i format and -o format
1265 which specifies input format and output format respectively - where
1266 format is one of "marc", "marcxml", "line", "marcxchange".
1268 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1269 does not print anything except warnings for records.
1271 For yaz-marcdump, added support for MARC split into files (-s) with a given
1274 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1275 spec, at http://www.loc.gov/standards/sru/record-update/
1276 This has changed the binary layout of the following structs:
1277 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1278 bend_update_rr . Patch by Ko van der Sloot.
1280 Added GFS utility function bend_assoc_is_alive which returns 1 if
1281 association is still alive (client is connected); 0 otherwise (client
1282 closed connection). This allows busy servers to stop working for
1285 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1286 been a separate piece of software. This version of ziffy has been modified
1287 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1289 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1291 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1292 Client code may now interrogate options such as "init_opt_sort" to
1293 find out whether the server claims to support various options.
1295 --- 2.1.40 2006/11/27
1297 Added utilities yaz_{set,get}_esn to set/get element set name from
1300 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1301 of YAZ and has been so since YAZ 2.1.10.
1303 Implemented ZOOM_record_error which returns error information for
1304 record (surrogate diagnostic).
1306 --- 2.1.38 2006/10/31
1308 Updates for SRU Update by Ko van der Sloot:
1309 1. Changed name from "operation" to "action"
1310 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1311 versions in the code, marked as 'backward compatible'.
1312 3. Added diagnostics for SRU Update.
1314 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1316 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1318 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1320 For GFS, fixed problem with SRU diagnostic 'First record position out of
1321 range' being issued for 0 hits.
1323 zoomtst10 part of Windows Build.
1325 --- 2.1.36 2006/10/13
1327 Implemented yaz_filepath_comp which splits a path into file path
1328 components (required by Zebra 2.0.3+).
1330 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1331 BSD inspired license until now so this should not have any real impact on
1332 anybody. See http://www.opensource.org/licenses/bsd-license.php
1334 Fixed bug #687: Missing log lines.
1336 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1339 Fixed bug #689: SRU diagnostics to be added.
1341 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1342 whether a connection is idle (no more work do do).
1344 --- 2.1.34 2006/10/04
1346 Change type of optval from long to int for invocation of setsockopt with
1347 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1349 Added support for specifying the max log file size for the Generic
1350 Frontend Server. The size is given with option -r.
1352 --- 2.1.32 2006/09/21
1354 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1356 --- 2.1.30 2006/09/17
1358 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1361 Fixed bug in Generic Frontend Server that could cause a server to stop
1362 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1364 For the generic frontend server, the maximum record size is used as maximum
1365 size of incoming packages (SRU + Z39.50). The value until was previously
1366 only used in Z39.50 Init negotiation and, later, in a session controlled
1367 sizes of records returned. This is controlled using -k option. It can be
1368 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1370 --- 2.1.28 2006/09/04
1372 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1375 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1377 New option for yaz-marcdump -lpos=value which allows setting a portion
1378 of MARC header to a certain value.
1380 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1382 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1383 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1385 --- 2.1.26 2006/08/15
1387 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1390 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1392 --- 2.1.24 2006/08/08
1394 Fixed MARC ISO2709 encoding routines to deal with character set
1397 Minor changes to GFS logging. Database included in search request log
1400 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1401 cached/multiple records.
1403 Shared libraries are built by default on Unix+configure.
1405 Changed cql2pqf transformation to use a different evaluation order. The
1406 new order is: always, relation, structure, position, truncation, index
1407 and relationModifier. Old order was: always, relation, relationModifier,
1408 structure, index, position, truncation. Note that the the latter ones
1409 override former ones for identical attributes.. The new scheme means that
1410 it is possible to override any existing attribute with a relationModifier.
1411 And also that it is possible to override everything for the index rule
1412 (except the ones listed in relationModifier). No order is perfect but this
1413 one, we believe, covers more real cases.. The "always" should have been
1414 called "default", since the attributes there can be overridden with all
1417 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1418 compilation phase, but also for yaz-config --cflags output. This allows
1419 us to have public headers with Libxml2 stuff in them . It should also,
1420 eventually, make Libxml2 checks redundant in packages using YAZ, such
1423 --- 2.1.22 2006/06/15
1425 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1426 stored in uri, message and details.. Previously diagnostics were stored
1427 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1428 compatibility.. but he's probably the only one affected, so.
1430 Added support for CCL, compiled on the client side, in ZOOM-C. This
1431 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1432 input; the resulting query objects can be used for for searching with
1433 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1435 YAZ' configure searches for OpenSSL by default.
1437 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1438 SL_CTX_use_certificate_file. See
1439 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1440 for more info. Thanks to Ko van der Sloot.
1442 --- 2.1.20 2006/06/02
1444 Bug #600: SRU GET, POST support for yaz-client. Introduced
1445 command 'sru' which selects method SOAP/GET/POST.
1447 Allow missingValueAction to be specified for the sortspec string -
1448 function yaz_sort_spec. By default, the missing value action is null.
1449 Use ! to specify "abort". Use = followed by stringvalue to specify default
1452 Ensured that Present-handler (if defined) is called in GFS before any call to
1453 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1454 searchRetrieve requests.
1456 Documentation for YAZ is now based on the Docbook XML/XSLT using
1457 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1458 is no longer depending on jade/openjade or docbook-to-man scripts.
1459 PDF is no longer part of the distribution - but can optionally be
1460 made using DSSSL/jadetex or FOP.
1462 Added retrieval handling support in Generic Frontend Server to support
1463 conversion between MARC/XML as well as XSLTtransforms. See
1464 etc/yazgfs.xml for an example.
1466 Added Authentication support to Generic Frontend Server in SRU
1467 mode. Authentication using HTTP Basic is supported, as is the use
1468 of 'x-username' and 'x-password' parameters in the request itself.
1470 Added support for a new character set MARC8s identical to MARC8 except
1471 that it converts combined characters to single Unicode characters in the
1472 Latin-1 range (when possible).
1474 --- 2.1.18 2006/04/24
1476 ASN.1 compiler 0.4: generates brief Doxygen file header for
1477 generated .h/.c files.
1479 Utility yaz_iconv now supports conversion to MARC-8.
1481 New facilities for the MARC module. The reading - and writing of
1482 content are separate methods for the yaz_marc_t handle. The following
1483 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1484 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1485 format). Write functions have prefix yaz_marc_write_.. The existing
1486 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1487 available. Removed support for OAI-MARC and simplexml (not the
1488 simplexml from PHP5).
1490 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1491 to be returned for this connection.
1493 --- 2.1.16 2006/03/31
1495 Allow multiple languages and charsets to be specified with
1496 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1497 negcharset iso-8859-1,utf-8
1499 Translation of proximity nodes from CQL into PQF now works.
1501 Moved to automake 1.8, 1.9.
1503 Added function yaz_log_set_handler which allows a log handler to be
1504 installed. This handler will be called for all log messages. Output
1505 to file is also produced; but that can be disabled by passing NULL
1506 fname to yaz_log_init_file.
1508 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1510 For SRW (including GFS), accept application/soap+xml as content-type
1513 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1514 produces NO stylesheet reference even if a default stylesheet is specified
1517 --- 2.1.14 2006/03/14
1519 Updated Windows package to include yazd.dll + yazd.lib for the
1520 Development component.
1522 If the environment variable YAZ_LOG is set, then it is used as a
1523 string indicating the default level of logging to use if not
1524 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1525 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1526 used as before. So, for example, to omit warnings from YAZ logging,
1527 export YAZ_LOG=-warn
1529 cql_transform() now map structure and other attributes before indexes,
1530 so that index-specific structures and other attributes can override
1531 defaults. So now a combination of mapping specifications such as:
1533 index.dc.date = 1=date-modified 4=5
1534 does the right thing.
1536 cql_transform() now also respects the "always" mapping specification,
1537 which establishes an initial set of attributes to be used for all
1538 terms except where overridden by more specific attributes associated
1539 with the index, relation or modifier.
1541 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1542 which mode to use; one of "post", "get" or "soap" (SRW, default).
1544 Fixes for yaz_iconv routines: changed trie-based character set conversions
1545 to use only non-negative values for bit fields due to Sun's C compiler not
1546 supporting negative values.
1548 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1549 sequences where not read correctly. Fix by Rustam Usmanov.
1551 Updated win/makefile to use options, settings which makes things
1552 compile with VS C 2005.
1554 --- 2.1.12 2006/02/01
1556 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1558 In ZOOM socket code, use select instead of poll on MacOSX.
1560 ZOOM-C now support client-side compilation of CQL into RPN that is
1561 sent to the server, enabling CQL to be used against all Z39.50
1562 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1563 ZOOM_query object, and submit it using ZOOM_connection_search().
1564 The CQL-to-RPN translation uses a configuration file, the name of
1565 which must be specified in the Connection's "cqlfile" option.
1567 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1568 function, which takes as its start-term parameter a ZOOM_query object
1569 (which may have had either CQL or RPN set into it).
1572 --- 2.1.10 2005/11/29
1574 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1575 GFS to support this as well. Backend handler, bend_srw_update, does the
1576 update work. Code contributed by Ko van der Sloot.
1578 Allow retrieval of Search Result-1 information in ZOOM by the use of
1579 options that are attached to a result set. ZOOM documentation updated
1582 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1583 UTF-8 conversion. Patch by Raj Patel.
1585 Added option -m to GFS to control formatting of timestamps in log file.
1587 Added 'exit' as synonym for 'quit' in yaz-client
1589 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1590 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1591 for the new members. Patch by Ko van der Sloot.
1593 Added support for SRU POST. It is supported for content-type
1594 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1596 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1597 Instead make the library libyaz.la multi-threaded. Threading as a whole
1598 can still be disabled by configure option --disable-threads. Previosly,
1599 with older GLIBCs there were problems with MT libs under Apache. This
1600 has now been fixed a long time ago.
1602 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1605 CQL module modified to be case insensitive for relations/indexes/operations.
1607 Fixed bug in CQL transform code: incorrect value relationModifieder
1610 Added 'show all' command for yaz-client which retrieves all results
1613 Added new yaz-client, xmles, which takes a (private) OID and
1614 a document to be sent as an extended service request.
1616 Describe new yaz-client commands wait_response and set_auto_wait.
1618 Increase TCP/IP listener backlog from 3 (which I am guessing was
1619 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1620 that the socket will queue as many incoming connections as it's able
1621 to handle ongoing connections. In other words, it will never now
1622 refuse a connection that it would be able to handle merely because
1623 it's not got around to accepting() enough of the pending connections
1624 yet. This is the behaviour anyway under Linux, where the listen()
1625 argument is ignored; but not under BSD and on systems such as
1626 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1627 YAZ-based servers should now be uniform across operating systems in
1630 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1631 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1632 This allows yaz-marcdump to read large MARC batches (>2 GB).
1634 Modified all YAZ source files - except the source which is auto-generated
1635 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1638 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1639 corresponding to the existing *_setl() function. These allow option
1640 values containing arbitrary valuues.
1642 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1643 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1644 except that it returns an indicator of whether or not the sort
1645 criterion was accepted (0 for OK, -1 for invalid).
1647 --- 2.1.8 2005/06/07
1649 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1650 MARC output rather than returning "new" buffer.
1652 yaz-client warns about unknown init options.
1654 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1656 --- 2.1.6 2005/05/24
1658 Added support for SRW sort in Generic Frontend Server. Patch
1659 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1660 sortKeys - or NULL if none is provided.
1662 Fixed bug #307: It was impossible to specify indefinite/no timeout
1663 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1666 Added support for multiple languages and charsets to be specified in
1667 ZOOM. Each charset/language is separated by a blank. If negotiation is
1668 in effect in init-response, Option
1669 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1670 Code based on patch by Vasiliy Osadchuk.
1672 Fixed bug #306: infinite recursion that occurred when calling
1673 yaz_log_level_init as the first call (before other log level or
1676 Fixed bug in scan handling in front end server: if preferred-Position-In-
1677 Response was non-present, a NULL pointer referece was performed.
1679 --- 2.1.4 2005/04/26
1681 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1682 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1683 now defined for all those error codes. So instead of putting 109 in
1684 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1685 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1687 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1690 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1692 Program yaz-client now exits and produces an error message if multiple
1693 Z39.50 servers are specified on the command line (none or one allowed
1696 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1699 --- 2.1.2 2005/03/16
1701 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1703 Fixed bug #272: Preserve spacing for CCL terms.
1705 --- 2.1.0 2005/03/14
1707 Added support for virtual hosts and multiple backend servers for
1708 the YAZ frontend server. The configution is XML based and
1709 support specificition of CQL to RPN mappings and explain information.
1710 See section "Virtual Hosts" in the YAZ manual.
1712 Extended OPAC display utility. OPAC display utility renders
1713 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1714 to supplement yaz_marc_decode_wrbuf.
1716 Fixed a bug in MARC decoder that could caused it to crash for some
1717 invalid MARC records. More diagnostics and warnings where added in
1718 XML output (warnings, etc are stored in comments).
1720 --- 2.0.34 2005/02/08
1722 Fixes for UNIX domain sockets. Bug #261.
1724 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1726 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1727 Added yaz_marc_subfield_str which defines subfield lead string which is
1728 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1729 yaz_marc_endline_str which defines end of fields string used in
1730 YAZ_MARC_LINE format. Default string is newline.
1732 Experimental support for MarcXChange. This format can be produced
1733 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1734 http://www.bs.dk/standards/MarcXchange.xsd
1736 Added yaz-client commands scansize that sets maximum number of
1737 entries to be returned by scan.
1739 --- 2.0.32 2005/01/11
1741 Added support for SRW scan in yaz-client and Generic Frontend Server.
1743 * Added whereInList member to SRW Scan Term.
1745 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1747 Fixed NMEM system to return aligned blocks on the smallest boundaries
1748 that are suitably aligned for all possible types on the particular
1749 architecture YAZ is being built for.
1751 --- 2.0.30 2005/01/04
1753 Fixed numerious warnings that was issued with newer versions of GCC.
1755 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1756 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1759 Make YAZ Generic Frontend Server slightly faster.
1761 Enhance (and reduce) logging for Generic Frontend Server.
1763 Revert YAZ log system so that it flushes every write operation
1764 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1766 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1767 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1768 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1769 will effectively disable old definitions.
1771 --- 2.0.28 2004/11/09
1773 Added yaz_log_time_format which specifies log format using
1776 Added yaz_log_module_level which returns mask for a module. Value
1777 is non-zero mask a if module is enabled; zero if disabled.
1779 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1780 in include/yaz/cql.h.
1782 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1784 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1786 Fixed bug #172: RPM builds does not enable SSL.
1788 Doxyfile.in part of dist. Doxyfile generated by configure.
1790 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1791 are given and the corresponding component does not exist.
1793 Extend CCL documentation in YAZ reference. Describe r=r.
1795 --- 2.0.26 2004/10/01
1797 Fixed MARC->MARCXML conversion to properly deal with
1798 fields, subfields, indicators having non-ASCII characters.
1800 Fixed MARC->MARCXML conversion so that ASCII control characters
1801 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1804 Added YAZ GFS support for conversion from Z39.50 surrogate
1805 diagnostics to SRW surrogate diagnostics.
1807 Bug fix: YAZ GFS did not return schema in explainResponse.
1809 --- 2.0.25 2004/09/30
1811 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1812 now converts recordSchema to elementSetName as well as schema URI.
1814 Fixed bug in COMSTACK that prevented HTTP request packages from being
1817 --- 2.0.24 2004/09/29
1819 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1820 does not require white-space before and after the dash in a range, e.g.
1821 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1824 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1825 due to new GCC removing "redundant" code.
1827 Added yaz-client commands scanpos and scanstep that sets preferred
1828 position and step-size for scan.
1830 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1832 Added CCL utility ccl_qual_buf which parses one or more CCL
1833 spec lines in a buffer.
1835 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1836 of name and value - ignoring empty lines and comments.
1838 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1840 Added odr_get_element_path which returns current element path for an
1841 ODR handle. This utility is useful in error handling or user-defined
1844 Added ODR_PRINT utility odr_set_stream which is is a more generic
1845 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1846 to a write function and pointer to close function. The close function - if
1847 non-NULL - will be called during odr_destroy.
1849 Fixed bug in CCL parser where truncation char was not removed from
1850 right side when truncation=both was in effect.
1852 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1855 --- 2.0.23 2004/08/11
1857 Fix buffer overrun in CQL parser when dealing with proximity (%).
1859 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1860 to UTF-8/UCS conversion is now only based on codetables.xml.
1862 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1864 --- 2.0.22 2004/08/06
1866 Add support for more "commit changes" in ZOOM (uses Extended Services).
1868 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1871 Yet another small fix for configure of SSL.
1873 --- 2.0.21 2004/05/14
1875 Fix SSL libs for configure when --with-openssl=DIR is given.
1877 --- 2.0.20 2004/05/10
1879 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1881 SSL comstack now uses yaz.pem certificate file on server side
1882 by default. Certificate filename can be configured by calling
1883 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1885 Fix bug regarding multiple calls to ZOOM_connection_connect.
1887 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1889 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1890 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1892 ZOOM now allows inspection of X509 peer certificate for verification.
1893 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1895 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1896 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1897 as "modular" but it simplifies things.
1899 Added cs_get_peer_certificate to that returns peer X509 PEM.
1901 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1902 NULL if SSL is unavailable.
1904 Documentation about MARC decoding tools.
1906 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1908 --- 2.0.19 2004/03/30
1910 Rename CHANGELOG to NEWS to follow GNU style packing.
1912 Fix bug with missing initialization of member in init_diagnostics.
1913 This bug affects threaded version of GFS server.
1915 --- 2.0.18 2004/03/20
1917 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1920 Ensure zlib.dll is packed with Windows install.
1922 --- 2.0.17 2004/03/17
1924 Fix encoding of xsd:string to use text instead of CDATA.
1926 Fix endless loop in CQL parser with unbalanced ".
1928 Use a more compact way to store MARC-8 conversion tables.
1930 --- 2.0.16 2004/03/16 Debian only
1932 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1935 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1940 --- 2.0.15 2004/03/01
1942 Another fix for decoding of XML packed records.
1944 --- 2.0.14 2004/02/25
1946 Fixes for Chunked encoding. White space not ignored after length spec.
1948 Update NS and use default NS for SRW diagnostic elements.
1950 --- 2.0.13 2004/02/23
1952 Implement ZOOM_resultset_cache_reset which resets record cache.
1954 Implement ZOOM_resultset_sort which sorts a result set.
1956 Implement chunked HTTP transfer.
1958 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1960 --- 2.0.12 2004/02/16
1962 Added member 'schema' to bend_explain_rr structure so that backend
1963 can specify explain record identifier. Defaults to Zeerex 2.0.
1965 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1967 --- 2.0.11 2004/02/16
1969 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1972 Added init command for yaz-client which sends "extra" init request.
1974 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1975 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1977 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1979 Make ZOOM error code for "invalid query".
1981 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1983 --- 2.0.10 2004/02/05
1985 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1988 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1990 Added option -p <file> to make Generic Frontend Server to write PID file.
1992 Added option -D to put Generic Frontend Server in background on its own.
1994 Make ZOOM C recognize option "password". If unset, "pass" is used
1995 (for backwards compatibility).
1997 Fixed a bug in Generic Frontend Server that could make it crash if a
1998 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2001 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2002 Must be issued before open, in order to be in effect.
2004 --- 2.0.9-6 2004/01/12 Debian/Windows
2006 Make the SRU server more picky WRT unknown params, etc.
2008 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2010 New YAZ client command, options, that sets Z39.50 options.
2012 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2013 options from a string of tokens (one token for each option bit).
2015 Update SRW diagnostic code messages.
2017 --- 2.0.9-5 2004/01/07 Debian/Windows
2019 Handle user defined stylesheet for SRW/SRU.
2021 --- 2.0.9-4 2004/01/06 Debian/Windows
2023 Fix bug in decoding of Content-Length.
2025 --- 2.0.9-3 2004/01/06 Debian/Windows
2027 Fix a bug with decoding of XML packed records.
2029 --- 2.0.9-2 2004/01/05 Debian only
2031 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2033 Fix bug in SRW/SRU diagnostics decoding.
2035 --- 2.0.9 2004/01/05
2037 Fixed bug in Generic Frontend Server which could drop records exceeding
2038 preferred message size. Reported and fixed by Irina Dijour.
2040 Fixed calculation of package size for structured records in Generic
2041 Frontend Server. Reported and fixed by Irina Dijour.
2043 Fixed namespace for SRW/SRU diagnostics.
2045 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2047 --- 2.0.8 2003/12/22
2049 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2050 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2053 CQL changes to reflect recent changes to the specification:
2054 * Documentation talks about context sets instead of index sets.
2055 * Documentation talks about indexes instead of qualifiers.
2056 * The CQL-to-PQF transformer's configuration file now uses
2057 "index.set.name = <attributes>" instead of the old form
2058 "qualifier.set.name = <attributes>". (Both forms are still
2059 understood but the latter is deprecated.)
2060 * CQL terms with no explicit index specified are now interpreted as
2061 cql.serverChoice instead of srw.serverChoice (which of course
2062 behaves exactly the same.)
2064 --- 2.0.7 2003/12/16
2066 MARC conversion can now generate ISO2709 output in another
2067 character set. yaz-marcdump uses this facility if you invoke it
2070 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2071 functions from there can be used from C++.
2073 --- 2.0.6 2003/12/04
2075 Frontend server now transfers memory from decoded packages to stream
2078 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2079 references to show up.
2081 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2082 the ZOOM Abstract API. The older names for the same options are still
2083 also supported for the benefit of old applications.
2085 ZOOM-C supports "implementationId" and "implementationVersion" options
2086 to go along with "implementationName". These allow the user code to
2087 specify identification strings to be sent to servers.
2088 Add OID for the new ExtLite attribute set.
2090 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2091 as requested/supplid by Ere Maijala <ere@atp.fi>
2093 For generic frontend server, reverse the order of
2094 "toolkit-supplied / application-supplied" strings sent as implementationId,
2095 Name and Version. Also, remove the spaces around the slash. This brings
2096 the GFS in line with the behaviour of ZOOM-C on the client side.
2098 Add function ZOOM_scanset_display_term.
2100 yaz-client shows scan displayTerm if present.
2102 Utility yaz-iconv is now installed by default along with the man page
2105 Extend configure check for OpenSSL to use pkg-config where available (such
2108 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2109 server to specify uid/gid/mask for socket using the format
2110 unix:[user=uid,][group=gid,][umask=mask,]file=path
2111 If file= is omitted the existing format is assumed, e.g.
2113 in which case the mask is 0666 (rw for everybody).
2115 Major restructure of YAZ source. All source in libyaz is in src directory.
2116 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2117 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2119 Added man page for utility yaz-marcdump (used to be called marcdump).
2120 yaz-marcdump is installed by 'make install'.
2122 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2123 of incoming package failed.
2125 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2127 Change prototype of odr_perror: add const to message string.
2129 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2131 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2132 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2133 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2134 DNS lookup. There should not be any compatibility problems with this
2135 assuming that blocking=1 or 0 is used.
2137 Fix bad reference in UNIX comstack in function cs_addrstr.
2139 Fix for compilation on AIX.
2141 The generic front-end server (server/seshigh.c) now supports returning
2142 Init diagnostics to the client in User-information-field, in
2143 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2146 --- 2.0.4 2003/09/04
2148 Allow any CQL relation (not just all,any,exact,scr).
2150 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2151 that features the same UI.
2153 Implemented command update0 in YAZ client which is equivalent to
2154 update but uses old of Ext Update ASN.1.
2156 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2157 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2158 Previously no OID was used for this info.
2160 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2161 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2162 returns 'malformed search term' otherwise.
2164 SortResponse member resultCount now set to NULL in sort handler of
2167 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2170 Add three new utility functions for translating OIDs between various
2171 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2172 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2173 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2174 char *oid_to_dotstring(const int *oid, char *oidbuf);
2175 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2177 Reverted modifications for ES Update definition for z_IU0Update
2178 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2179 is back to YAZ 2.0.2.
2181 String value attributes for CCL parser.
2183 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2184 which their FirstSearch server returns in Init responses, sometimes
2185 carrying useful diagnostic information when Init fails. This has the
2186 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2187 "z39.50/oclcui.asn", where its definition is somewhat different from
2188 what OCLC document on their web-site, as required to interoperate with
2191 Support for anonymous authentication in yaz-client. Use the command
2194 * Fix the OID of the Index Data-local "admin" Extended Service from
2195 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2196 the 1000, which indicates a locally-defined OID, was a mistake.
2198 --- 2.0.3 2003/06/20
2200 Fix CCL directive @case handling so that it affects string match for
2201 both CCL keywords and qualifiers.
2203 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2204 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2205 Decoder has been updated with ASN.1 changes as listed in
2206 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2207 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2208 z_IUUpdate, remains unchanged.
2210 ZOOM_record_get may now return a record in a specific character set.
2211 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2212 "from" is the character set of record as returned by target. "to" is
2213 the character set to be returned. If omitted, "to" is UTF-8.
2215 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2217 New ODR utility, odr_getelement, which returns name of element for
2218 which encoding/decoding failed.
2220 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2221 in cases where a required element was omitted.
2223 Bug fix: some MARC8 sequences were not converted.
2225 New ZOOM option "step" which specifies number of records to be
2226 retrieved in one chunk. Used in conjunction with "start" and "count".
2228 SRW support for yaz-client. Use scheme http: to use it, e.g.
2231 yaz-client no longer does (un)intelligent character set conversions
2232 by default. Can be enabled with charset and marc_charset commands.
2234 xmalloc trace fix for 64-bit systems such as DEC alpha.
2236 Solaris 2.6 compile fix.
2238 New function, cql_strerror() translates SRW error codes, as returned
2239 by cql_transform_error(), into human-readable English strings. Used
2240 in yaz-client diagnostics when appropriate.
2242 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2243 converts it into a type-1 query which is sent to the server. This
2244 makes CQL available for use with all Z-servers, as opposed to the tiny
2245 minority that can handle CQL queries themselves.
2247 --- 2.0.2 2003/04/28
2249 New Debian package layout similar to the Redhat Package layout.
2251 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2252 and search result respectively.
2254 --- 2.0.1 2003/04/25
2256 Redhat package is now several packages: libyaz (runtime libraries),
2257 libyaz-devel (development and documentation, and yaz (utility programs).
2258 Package spec file by Morten Bogeskov.
2260 New member 'schema' in struct bend_fetch_rr which the name of requested
2261 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2262 handler MAY set this to reflect the schema of the returned record.
2264 New member 'display_term' in struct scan_entry. GFS now sets member entries
2265 and allocates scan entries to be filled by user scan handler. In previous
2266 version, entries member was allocated by the scan handler. That still works,
2267 but the GFS will ignore member display_term - assuming it was NOT set by
2268 the handler. The fact that the GFS now allocates the entries both allows
2269 for new members and makes a scan handler easier to write.
2271 Fix CQL lex buffer overflow.
2273 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2274 SRU default recordPacking is string.
2276 SRU protocol support for frontend server.
2278 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2280 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2282 Added scan for the ZOOM shell (zoomsh).
2286 * String Identifers for Schemas (Amendment 5).
2287 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2288 Old definition for schema
2289 Odr_oid *schema; /* OPT */
2294 Z_InternationalString *uri;
2295 #define Z_Schema_oid 1
2296 #define Z_Schema_uri 2
2299 * resultCount parameter to Sort Response (Amendment 1).
2300 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2302 Support for SRW 1.0 over HTTP. This is an optional feature and
2303 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2306 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2307 on the same port. SRW SearchRetrieveRequests are mapped
2308 to bend_init,bend_search,bend_fetch,bend_close.
2310 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2312 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2313 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2315 ZOOM connections are SRW based if schem http is used for hostname
2316 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2317 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2319 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2320 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2321 distance=n, order=true/false, relation=le, prox unit=word. If
2322 n is omitted, distance 1 is used.
2324 Fixed problem with C compiler include path in wrong order.
2326 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2327 on Solaris. Patch from Ko van der Sloot.
2329 New MARC decode API. All new functions operate on a yaz_marc_t
2330 handle. The most important new functions are: yaz_marc_create,
2331 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2332 decode and destroy respectively. Decoder can produce formats
2333 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2334 include/yaz/marcdisp.h.
2336 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2337 to UTF-8, UCS-32, wchar_t or Latin-1.
2339 * Prototypes for yaz_iconv_-functions moved to separate header
2340 include/yaz/yaz-iconv.h.
2342 Make a few private functions 'static' in unix.c. This prevents
2343 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2345 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2346 are set when Init Response is received.
2348 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2349 but returns diagnostic set as well.
2351 New function yaz_strerror which is a portable wrapper for
2352 strerror/strerror_r/GetLastMessage.
2354 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2355 is returned for MARC. If type is "oai", then OAI MARC is returned.
2357 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2360 --- 1.9.2 2002/11/26
2362 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2364 Fix bad race conditions on SIGTERM and terminate gracefully in
2367 Move retrieval (data1) module to Zebra since nobody seems to be
2370 Add GRS-1 render for ZOOM using same format as yaz-client.
2372 --- 1.9.1 2002/10/05
2374 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2376 Fix broken ESpec handling in data1 module.
2378 SGML reader parses comments and makes them part of the data1 tree.
2380 Added several type casts so that YAZ compiles as C++ code.
2382 ZOOM didn't handle PDU encoding failures properly.
2384 Added more Bib-1 diagnostics (approved extensions).
2386 GNU configure: better check for iconv.
2388 More portable use of accept, getpeername. Check for socklen_t. Use
2389 int/size_t if socklen_t is not defined.
2393 PQF parser rejects bad queries - including those with extra
2394 characters in them. PQF parser used to silently ignore that.
2395 Cleaner API for PQF added, which allows you to get detailed
2396 error information for bad queries (see yaz/pquery.h).
2398 Fixed bug in ZOOM_record_get for type "database".
2400 Implemented mini iconv library supporting conversions between
2401 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2403 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2405 --- 1.8.9 2002/08/20
2407 Fixed ZOOM C record cache so that preferredRecordSyntax and
2408 elementSetName is used to check for already fetched records.
2410 --- 1.8.8 2002/08/02
2412 Added three members in bend_initrequest structure to facilitate
2413 character set negotiation.
2415 Fixed a bug in frontend server that could cause indefinite
2416 loops under rare conditions.
2418 Revised character set utilities (charneg.h) so that encoding
2419 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2421 For PQF, directive @term <type> sets term type for Scan/Search.
2422 Here <type> is general, string, numeric, null. The term type
2423 is inherited - just like @attr.
2425 New call odr_set_charset that sets character set conversion for
2426 international-strings on a ODR stream. Prototype is:
2427 int odr_set_charset(ODR o, const char *to, const char *from);
2428 The InternationalString is still represented as C string in YAZ
2429 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2430 won't). On the protocol level, you can use any encoding.
2432 Support for UNIX sockets in ZOOM.
2434 Solaris recv sometimes returns errno == ENOENT. It is treated as
2435 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2437 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2438 both client and server. Code by Morten Bogeskov.
2440 --- 1.8.7 2002/05/22
2442 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2443 that they can be used directly from Visual Basic. You must recompile
2444 your windows APP if you're using ZOOM.
2446 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2447 Commands "lang" and "charset" sets language and character set respectively.
2448 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2449 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2451 Attributes from multiple CCL fields may be OR'ed rather than merged
2452 using directive "@field or". Fields are still merged by default -
2453 equivalent to "@field merge".
2455 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2458 Fixed bug in zget for parameter ExtendedServicesResponse.
2462 --- 1.8.6 2002/03/25
2464 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2466 Client displays USR.1:SearchResult-1 (hits per term).
2468 Additional Search Info for search in Generic Frontend Server.
2470 Fixed CCL parsing of "field=s".
2472 WIN32 installer - using the excellent NSIS software from nullsoft.
2474 Fixed CCL parsing of "field = - <number>".
2476 Added function yaz_marc_decode that decodes MARC for line mode
2477 display or XML (similar to that used by JZKit).
2479 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2480 Z39.50. But ISO/ILL was, however.
2482 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2483 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

2488 --- 1.8.5 2002/02/03
2490 New YAZ client features: Command completion and new commands:
2491 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2492 Code provided by Jacob Poulsen.
2494 New call oid_trav, that visits all registered OIDs via callback.
2496 Function ZOOM_record_get now returns const char pointer rather than
2497 void pointer. It saves a lot of type casts.
2499 For YAZ client, command "auth" now allows you to set authentication
2500 in IdPass style. It is enabled when three tokens are given - order
2501 is user, group and password.
2503 Fix memory leaks in MARC record handling for ZOOM.
2505 New option for YAZ client, -k <kilobytes> that sets
2506 maximum record size. Similar to -k option for generic frontend
2507 server and yaz-ztest.
2509 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2511 Prefix query parser reports "fail" when bad attribute set is given.
2513 Fix in MARC decoder. Proximity logging. Fix for attribute set
2514 in scan handler for server. Patches by Shigeru Ishida.
2516 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2519 Configure option --with-openssl=<dir> now works when a directory is
2520 specified. Patch provided by Morten Bogeskov.
2522 New option for YAZ client, -u <auth>, that sets authentication.
2524 ZOOM fix: error information was sometimes "missing", since error
2525 was cleared/reset too when it shouldn't.
2527 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2529 --- 1.8.4 2002/01/04
2531 Scan for ZOOM API. New object ZOOM_scanset. New functions
2532 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2533 ZOOM_scanset_destroy.
2535 New ZOOM function, ZOOM_connection_last_event, that returns type
2536 of last event (such as "receive data", "send data", "apdu received",
2539 New ZOOM option, schema, that specifies schema for retrieval.
2541 New CCL feature. Qualifiers can be aliases for one or more
2542 other qualifiers (if more than one is given, OR is used).
2544 ZOOM uses named result sets if target supports it.
2546 Two new YAZ client commands: . (dot, which sources a script of YAZ
2547 client commands), and ! (to execute shell command.). Implemented
2550 Working on Debian packages.
2552 --- 1.8.3 2001/11/19
2554 YAZ client enables named result sets only if target supports it.
2556 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2558 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2559 with key="host" to get same result.
2561 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2562 Function Z3950_resultset_record(s) returns references to records
2563 "owned" by resultset. To become owner use Z3950_record_clone.
2565 Function z_ext_record handles Extended Services. Thanks to
2568 --- 1.8.2 2001/11/12
2570 CCL Parser fix: ignore token comma when dealing with and-lists.
2572 Documentation updates for COMSTACK.
2574 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2575 Changed prototype Z3950_records. For some functions, int parameters
2576 were changed to size_t.
2578 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2581 New MARC decode/display function, marc_display_exl, which properly rejects
2582 non-ISO2709 records. YAZ client uses it.
2584 --- 1.8.1 2001/10/29
2586 Fix bug: local attribute set wasn't set correctly in PQF strings.
2590 * Old Z39.50 codecs no longer supported.
2592 Added ZOOM C binding. See http://zoom.z3950.org/
2594 Renamed states for COMSTACKs to avoid confusion with events.
2596 Implemented cs_look and proper cs_rcvconnect.
2598 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2600 Configure detects POSIX threads on OpenBSD.
2602 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2603 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2605 When error is returned from present handler, non-surrogate diagnostic
2606 is returned in present response (and fetch handler is no longer called).
2608 * Minor adjustments to pquery parser (PQF). Token characters may be
2609 escaped by using backslash (C-style).
2611 PQF parser allows string attribute values to be specified. For @attr,
2612 non-numeric characters after the equal-sign are treated as strings
2613 (e.g. @attr 9=title).
2615 CCL trunction character may be defined (@truncation in file)
2617 * function zget_ExtendedServicesRequest sets waitAction to
2618 waitIfPossible (was wait).
2620 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2623 CCL operator names may be set in field definition files (CCL_bibset).
2624 See ccl/bib1 for an example.
2626 Fixes in ASN.1 compiler for C++ compatibility.
2628 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2629 and "op_or" to avoid conflict with C++.
2631 Fixed problem with GNU readline detection on Redhat 7.0.
2633 Added step-size for Scan backend handler.
2635 Fixed bug that made the frontend server crash when no attribute
2636 set was specified for scan.
2638 Front-end server automatically switches to original working directory
2639 when installed as an NT service. Previously -w had to be specified to
2642 Added extended attributes for retrieval module (data1), so that data1
2643 records carry d1_readXML/SGML attributes. d1_read also supports
2644 null-data rules ( <tag/>)
2646 On UNIX when POSIX threads are available, a separate library libyazthread
2647 is created. Programmers should link with that library and the yaz library
2648 when using threads. The reason for the split was that some applications
2649 on Linux, such as Apache, doesn't work well when using shared objects that
2652 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2653 (or any frontend server) in SSL mode by specifying ssl: followed by
2654 address. Only tested on UNIX.
2656 Added feature for CCL module. Virtual structure s=al or s=ol generates
2657 and-list and or-list respectively instead of phrase search.
2661 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2662 log_mask_str. This was done to avoid name conflicts with other libraries
2663 (such as other PHP extensions).
2665 Added raw OID member for preferred record syntax (request_format_raw)
2666 and returned record syntax (output_format_raw) for backend fetch method.
2668 Config file yaz-config now accepts options so that it returns specific
2669 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2671 Shared library support for UNIX using GNU libtool.
2673 * Modified backend interface. Request/Response struct's replaced by
2674 one read/write C struct. For example bend_fetchrequest and
2675 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2676 Every handler - even search has to be registered in bend_init
2677 handler. This means that the YAZ library no longer refers to
2678 external functions and it makes it possible to make the whole
2679 thing a single DLL/SO.
2681 Added Segment handler for backend server.
2683 Added Zmbol/Zebra administrative functions to YAZ client.
2685 Threaded frontend server on UNIX (when POSIX Threads are available).
2686 Starting the server with option -T enables multi-threading.
2690 Added configure option --enable-comp/disable-comp to control use
2691 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2692 located in sub directory asn.
2694 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2695 in ${exec_prefix}/bin along with the other programs yaz-client and
2698 GNU automake used to maintain makefiles.
2700 Added several OID's.
2702 Changed retrieval module so that we can load records with no abstract
2703 syntax defined. Tagpaths in these records are fully composed of string
2706 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2710 On UNIX, the generated makefile now supports a proper 'make install'.
2711 The prefix can be set via GNU configure to set the install location
2712 (default is /usr/local).
2714 * YAZ programs client and ztest were renamed to yaz-client and
2715 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2716 locations, such as /usr/bin,/usr/local/bin,etc.
2718 * YAZ Header files were moved from include to include/yaz. YAZ Header
2719 files are referred to as include <yaz/log.h> rather than <log.h>.
2720 The YAZ include path (-I ..) is therefore the same as before. Programmers
2721 should update their #include statements or use -Ipath/include/yaz
2722 instead. The main motivation for doing this change is that YAZ header files
2723 can be installed in "standard" locations /usr/include,/usr/local/include
2724 without introducing conflicts, since ALL YAZ header files are stored
2725 in subdirectory yaz (under /usr/include for example).
2727 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2728 rather than project/workspace files. We switched because project files
2729 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2732 Changed name of logging function, logf, to yaz_log, to prevent name
2733 clash with some math-log functions. The YAZ header log.h defines logf
2734 to yaz_log (#define) so there should be no incompatibilities by this
2737 Added bend_start/bend_stop handlers for server. These handler are
2738 called on start/stop of server. For windows they are called whenever
2739 a service is started/stopped.
2741 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2742 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2743 in util/yc.tcl. The auto-generated C code structures are, in a few
2744 cases, incompatible with the old decoders. There are differences in the
2745 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2746 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2747 The preprocessor variable ASN_COMPILED is defined when the compiled
2748 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2749 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2750 wish to use the old encoders/decoders you can specify --disable-yc
2753 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2754 version so that it supports both new - and old version of DB Update
2756 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2757 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2758 change. The name parameter can be set to 0 in which no name is specified
2759 for the construction. The macros odr_implicit and odr_explicit sets name
2760 parameter to zero for the construction involved. New macros
2761 odr_implicit_tag and odr_explicit_tag are similar to the others,
2762 except that a name parameter is added. For programmers' that don't use
2763 ODR they probably only need to change the call to z_APDU and z_External.
2765 Added access control facility by interfacing the TCP wrapper library.
2766 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2767 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2768 name of the daemon and enables the access control as specified in
2769 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2771 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2772 den Dool <H.M.vdnDool@kub.nl>.
2774 Added reference ID parameter to most functions in server API - refer
2775 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2777 Changed name of ccl library to libccl.a (was ccl.a).
2779 Fixed bug in decoder for Explain (Category TargetInfo).
2781 Added support for GNU readline in client. Thanks to Jacob Poulsen
2782 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2784 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2785 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2786 IMPLEMENTATION! This change was made to the development version before
2787 the ZIG decided to retract the amendment. If any users MUST be
2788 compatible with the original Update definition, PLEASE CONTACT US, and
2789 we will include a separate definition corresponding to the old Update
2790 ES. Note that because of the change to the ASN.1 of the
2791 TaskPackageRecordStructure we cannot define a single structure that
2792 will support both versions.
2794 * Added const modifier to buffer parameter for some ODR/BER encoding
2795 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2796 completeWAIS, odr_dumpBER.
2798 Fixed bug in client.c which caused a crash when a scanResponse didn't
2799 contain positionOfTerm.
2801 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2802 * will cause an error in a client if a non-YAZ target sends both a
2803 * list of Scan entries and non-surrogate diagnostics.
2805 Retrieval module enhancements. Tag sets may be typed in the reference
2806 to it. From the .abs-file the "tagset" directive takes a third optional
2807 integer type for the tag set referenced. From a .tag-file the "include"
2808 directive takes a third optional type as well. The old "type" directive
2809 in the tag set itself is still recognized but acts as the default type
2812 Backend interface change. Individual Scan terms returned from bend_scan
2813 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2814 in include/backend.h.
2816 Retrieval module enhancements. Multiple tag sets and attribute sets may
2817 be specified in abstract syntax specs. Revised the error/warning for
2818 logging messages reported by the retrieval module when reading the
2821 Object Identifier system (oid_..) changed. The API is backwards
2822 compatible but the oid-routines now allocates new OID's when needed.
2823 Raw OID's may be specified in oid_getvalbyname.
2825 YAZ now uses GNU configure to generate Makefile(s).
2827 * Minor changes in some of the member names of DeleteResultSetRequest and
2828 DeleteResultSetResponse. See include/proto.h.
2830 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2831 and added member 'languages' in TargetInfo (which was missing).
2833 Changed the way attribute sets are handled in the retrieval
2834 module. These are now cached, just like the abstract syntaxes
2837 Changed YAZ so that it links with compiled ASN.1.
2839 Added Explain-schema definitions and mapping routines. The following
2840 Explain categories have been implemented: AttributeDetails,
2841 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2843 Fixed minor bug in Windows version of Server Library.
2845 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2847 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2849 Added EXTERNAL: UNIverse Resource Report (non-standard).
2851 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2852 ENUMERATED and SET OF.
2854 * Added 'const' to some of the char pointer arguments for the
2855 functions, data1_read_node, data1_getelementbytagname,
2856 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2859 Fixed bug in data1_insert_taggeddata - the last_child member of
2860 parent wasn't initialised.
2862 * Changed data1_read_record and data1_read_node so that the supplied
2863 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2864 doesn't refer to any parts of the "SGML"-buffer.
2866 Fixed bug in server library (Windows version of statserv_remove).
2868 * Changed code so that it compiles as C++. The type definition
2869 of Odr_fun which is a member of Odr_arm was changed. The result is,
2870 that an explicit typecast is needed for the fun pointer when
2871 using Odr_arm - as in:
2872 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2874 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2876 Implemented the new structured date and time definition as approved
2877 by the ZIG. Added schemaId element to the specificTag in Espec-1
2878 (also approved at the last ZIG). Thanks to RVDM.
2880 Added some Object identifiers (RVDM).
2882 Changed the Update Extended Service (RVDM).
2884 Added command "refid" to client which specifies referenceId for
2885 the following requests.
2887 Implemented extended service handling for server. See ztest.c
2888 for an example as well as backend.h. New handlers are registerd
2889 in the Init handler.
2891 * Changed interface for sort in server.
2893 Added new members to statserv_options_block. It allows a server
2894 to read options from another source than just the command line. Thanks
2895 to Charles Woodfield.
2897 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2898 renamed to zboolean. Some C++ compilers complained about the name.
2900 Minor changes to gils.abs. Added index 's' (sort) on title
2901 and date/time-last-modified.
2903 --- 1.4pl2 1998/1/30
2905 Fixed bug in server library regarding inetd mode (-i). This bug
2906 was introduced by release 1.4.
2908 --- 1.4pl1 1998/1/29
2910 Added sort facility in client and backend server interface.
2912 Fixed problem with dependencies in Makefile(s).
2914 Fixed bugs for encoders/decoders of extended services and
2917 Implemented sub-tree feature for schemas. Sub-trees are
2918 referenced in *.abs-files. See explain.abs for an example
2919 of the use of this feature.
2921 Modified bib1.att; local attributes for ANY didn't include
2922 ANY itself (only affects use of the retrieval module).
2924 Fixed bug in plain SGML reader in function data1_read_node:
2925 tags with prefix "var" was incorrectly interpreted as variants.
2927 Added feature "sub-schemas" to enable references to - and definitions
2928 of - group of elements.
2930 * Removed member parent from type data1_element (in data1.h).
2932 Implemented function odr_nullval() that returns the value of
2935 * Removed member num_children from data1_node (in data1.h).
2937 Made NT service interface part of the server library. The
2938 function statserv_main uses the NT service when required and
2939 calls the statserv_start / statserv_close routines.
2941 Routine zget_SearchRequest and zget_PresentRequest fills
2942 resultSetName/Id member with "default" instead of "Default".
2944 Fixed memory leak in server. Request queue member wasn't freed.
2946 Fixed nmem_exit so that memory is freed.
2950 Revised the CCL parser utility to be thread safe.
2952 Added function, oid_ent_to_oid, to replace the function
2953 oid_getoidbyent, which is not thread safe.
2955 * Added nmem_init and nmem_exit to initialize and release
2956 NMEM resources. Function nmem_init should be called once in the
2957 initial thread before NMEM/ODR is used. statserv.c and client.c
2958 have been changed accordingly. The change was necessary to make
2959 NMEM thread safe. The NMEM memory pool is shared amongst threads
2960 in a process. Unix-based applications will still work fine without
2963 Added NT Services interface for the the Z39.50 (statserv) Server.
2964 Refer to the ztest.c source on the usage.
2966 Windows 95/NT port using MSVC5.0. Project files are included in the
2969 * Defined new 'global' handle for the retrieval (data1) system. The
2970 new handled, data1_handle, describes the state of the data1 system.
2971 This handle is passed as first argument to virtually all
2972 data1 related routines. The functions data1_create and data1_destroy
2973 creates and destroys a data1 handle respectively.
2975 Added ODR encode stream member to all backend request structures
2976 init, search, scan etc. This stream should be used to allocate all
2977 memory used for the response when thread safe operation is needed.
2979 Changed the comstack utility, cs_addstr, to be thread safe. The
2980 returned hostname string returned by the function is now part the
2983 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2984 function. The cs_straddr takes a COMSTACK handle as argument, so this
2985 function must be used after cs_create and before bind/connect.
2986 This function is thread safe.
2988 Moved test server to 'ztest' directory - generic server code still
2989 in 'server' directory.
2991 Made prefix query (pquery.c) utility thread safe.
2993 Added new function modifier YAZ_EXPORT to 'export' public DLL
2994 functions when using windows (see include/yconfig.h).
2996 Added definitions to the OID database (util/oid.c) (RVDM).
2998 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3000 Added call to ccl_rpn_delete in client program.
3002 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3003 release of RPN structure.
3005 Added support for C++, headers uses extern "C" for public definitions.
3006 With input from RVDM.
3008 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3009 Thanks to Ronald van der Meer (RVDM).
3011 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3013 Added support for private extensions to the OID database
3014 (oid_setprivateoids()). Thanks to RVDM.
3016 Added optional, physical ANY (key replication)
3018 Fixed null-reference problem in GRS-1 output filter.
3020 Proximity operator added to Prefix Query Format (PQF).
3022 In test client command "base" accepts multiple databases.
3024 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3028 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3030 Smallish bug-fixes in the new encoders/decoders (explain).
3032 Bug fixed in DeleteRequest.
3034 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3036 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3038 Added SOIF syntax (using private OID for now) to retrieval module and client.
3040 Added Update extended service.
3042 Added SearchResult-1 additional info structure.
3044 Added optional CCL (ISO8777) interpreter as separate module. Available
3047 --- 1.2 1996/6/10 (1st anniversary release)
3049 Added Summary record syntax. Lightly tested.
3051 Added OPAC record syntax. Untested.
3053 Added ResourceReport service encoders/decoders. Untested.
3055 Fixed bug in z_Unit - wrong tagging on unitSystem.
3057 Fixed bug in the DiagRecs decoder.
3059 Added options for max PDU size and session timeout to frontend-server.
3061 Added documentation of query-language parsers and other supporting utilities.
3063 [frontend-server] Added Attribute set to the bend_scanrequest API.
3065 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3066 surrogate diagnostics were generated.
3068 [retrieval] Allow multiple local values for attribute.
3070 [retrieval] Allow multiple attributes per element in .abs files. index type.
3072 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3074 --- 1.1pl2 1996/4/10
3076 Minor changes, mostly specific to Zebra's requirements (retrieval)
3080 Repaired bug in frontend server when running multiple listening
3081 endpoints in dynamic mode.
3083 z_External() now won't break if a known, ASN.1 value comes encapsulated
3084 in an octet-string. The value will pass through unmodified in an Odr_oct.
3086 Added a bit of code to the demo client to decode & display
3087 ASN.1-structured records represented in the octet-aligned branch of
3088 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3090 Added z_ext_getentbyref() to the ASN module. Doc updated.
3092 * Completed the SCAN definition in the ASN module. This may break SCAN
3093 code based on older YAZ-versions at compile-time. The fix is easy -
3096 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3097 under the SCAN definition. Remember to initialize this, server-people.
3099 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3100 that this does not extend to ODR and ASN.
3102 Comstack allows insertion of established socket (primarily for
3103 inetd-operation of servers). Doc updated.
3105 Front-end server can now start from the inetd in TCP mode. Doc
3108 --- 1.0pl4 1996/1/24
3112 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3113 the rank and record number.
3115 Adjustments to the frontend server.
3117 Fixed diagnostic BER dumper. It ignored the file argument.
3121 Various changes to retrieval module.
3123 Changed the union discriminators of the protocol files from enums to
3124 ints paired with #defines.
3126 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3129 *Changed operator in the RPN structure to 'roperator', again to avoid a
3132 Fixed problems in Explain decoders/encoders.
3134 --- 1.0pl2 1995/12/6
3136 Memory bug in log module fixed.
3138 --- 1.0pl1 1995/12/5
3140 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3142 Bug in Explain DatabaseInfo module fixed.
3144 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3148 The shift to v1.0 signals that we now consider the *core* functionality
3149 of YAZ reasonably stable (the core being more or less equivalent to
3150 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3151 tested (Explain not at all - though that will happen soonish).
3153 Minor changes to code to support Windows port.
3155 Various minor changes after we're getting to use GRS-1 & co. more.
3157 Added Espec-1 format.
3159 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3160 of the protocol and it cannot be selected when encoding (maps into 'string'
3161 when decoding). Needed to talk to some servers.
3163 Demo client can request simple element set names.
3165 Added Diagnostic Format encoders/decoders.
3167 Added simple Close handling to frontend server (no hooks for resource
3168 reporting yet), and demonstration client.
3170 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3172 --- 1.0b3 1995/08/24
3174 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3175 handled incorrectly when records were requested in the searchResponse. This
3176 will only affect you if you use the frontend-server.
3178 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3179 Test-client will ask for and print GRS1. Ztest will return dummy records
3182 Added Explain encoders/decoders to the service-level API. Untested.
3184 Added Extended Services: Item Order encoders and decoders to the Service-
3185 level API. Untested. We could use a recent copy of the pertinent bits
3186 of the ILL protocol to add those bits.
3188 Added diagnostic format 1 encoders/decoders to the service-level API.
3191 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3192 odr_cons.c, which causes a more correct output.
3194 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3195 was always set to 0 when no records were requested in the searchRequest.
3197 * Added better external-handling. This shouldn't harm old code that
3198 *encodes* externals. It can break code that looks for a
3199 'single-ASN1-type' representation, since those types that are known
3200 are now decoded immediately. Look at the SUTRS sample code in
3201 seshigh.c and client.c. Documentation updated.
3203 Handling of structured records in bend_fetchresponse. Length -1 marks
3204 structured record, type is deduced from format field.
3206 --- 1.0b2 1995/06/27
3207 Fairly quick maintenance release to add SUTRS support.
3209 Fixed handling of SUTRS records in the demonstration client.
3211 * Added format field to the bend_fetchrequest and bend_fetchresponce
3212 structures of the backend API (frontend server). When the record is
3213 returned, the value of the format field is mapped to an OID. The
3214 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3215 of the record. The special value VAL_NONE in the bend_request means
3216 that no specific format was requested by the client. Documentation
3217 updated accordingly. Test server (ztest) will return a fixed dummy
3218 SUTRS record if your client requests SUTRS.
3220 Documentation updated accordingly.
3222 You can now set external libraries and RANLIB support in the top-level
3226 First public release.
