1 New function for daemon utility, yaz_daemon_stop .
3 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
7 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
8 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
12 YAZ daemon utility relays SIGUSR1 to child process.
14 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
15 would result in en empty database list - which in turn would result in
16 encoding failure for search.
18 Fix reading beyond string in yaz_sort_spec.
22 Add two new SRU diagnostics:
23 236: Access to specified database denied
24 1015: Init/AC: Maximum number of simultaneous sessions for Userid
26 Document the very useful ZOOM-C option "apdulog".
28 CQL to RPN: term may be passed through verbatim. This is enabled with
29 truncation.cql . The assumption being that the term is already CQL.
33 record_conv: leader spec may be given for marc element.
34 The leader spec is given as attribute leaderspec for element marc.
35 For example to convert a MARC21 record from MARC-8 to UTF-8:
36 <marc inputformat="marc" outputformat="marc"
37 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
39 record_conv: allow user-XSLT params. For example:
40 <xslt stylesheet="MARC21slim2DC.xsl">
41 <param name="myparameter" value="myvalue"/>
42 <param name="otherparameter" value="othervalue"/>
45 record_conv: fix error handling for missing marc charsets.
47 CQL: fix extra terms in wrong order.
51 record_conv: modify new API for conversion types. The conversion types
52 may be passed in new functions yaz_record_conv_configure_t and
53 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
55 Avoid mixed statement/variable declare; fixes compilation with Visual
60 Add non-standard SRU diagnostic: 235: "Database does not exist".
61 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
62 Update SRU to Bib-1 diagnostic maps accordingly.
64 CCL: add two new diagnostics for unsupported masking. The new
65 diagnostics are: "Embedded truncation not supported" and
66 "Single charcacter mask not supported".
70 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
74 Build YAZ for Ubuntu Oneiric.
76 CCL: allow parantheses for proximity operands. For example CCL query
77 (a) % (b) is now allowed.
79 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
80 marked dead, rather then being destroyed. If not, the session memory is
81 being free'd before the search/scan handler is finished. Also destroy
82 'request' memory in request_release rather than in various places,
83 which resulted in leaks from time to time.
87 cql_sortby_to_sortkeys: honor sort prefix.
89 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
90 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
91 The rpn2cql family of functions now always returns quoted CQL terms.
93 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
97 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
98 sequence is treated as one. For example, &&a=b&&&c& is identical to
101 --- 4.2.22 2011/12/05
103 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
104 APDUs for a connection to a WRBUF.
106 --- 4.2.21 2011/11/23
108 Fix cql_sortby_to_sortkeys. Completely broken before.
110 Make CCL's @truncation work again.
112 --- 4.2.20 2011/11/09
114 New ZOOM connection setting: tproxy. It's like proxy, but does not
115 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
116 to set resolved address + port for a connection outside ZOOM itself.
118 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
120 --- 4.2.19 2011/11/07
122 Fix uninitialized variable in Solr spell support (could cause SEGV
123 for SRU response decoding).
125 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
126 back-end's addinfo through into the ZOOM response addinfo.
128 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
129 they are separated by a colon and a space rather than simply
132 --- 4.2.18 2011/10/28
134 Add support for Solr spell-checking/suggestions through ZOOM.
135 If a Solr target has been configured correctly for spelling-checking
136 and suggestions, these will now be returned on the ResultSet option
137 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
139 --- 4.2.17 2011/09/28
141 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
142 with a flag whether to substitute escape sequences or not.
144 --- 4.2.16 2011/09/22
146 Fix nmem_strsplit_escape to substitute escape char properly.
148 New option for zoomsh -e , which makes it abort on first error and
149 return process exit code to indicate success/failure.
151 YAZ options utility supports special option -- which makes all it treat
152 all following arguments as non-options.
154 --- 4.2.15 2011/09/16
156 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
157 searched if absolute filename is given.
159 Fix conv_xslt() error-reporting when stylesheet is not found.
160 (The value of fullpath is meaningless in this situation.)
162 --- 4.2.14 2011/09/07
164 Fix problem in CQL sort node creation: un-initialized memory.
166 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
167 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
168 CQL sortby depending on whether Type-1 or CQL is actually sent to the
171 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
172 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
174 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
175 will make it possible to use both single-character mask (#) and wildcard (?)
176 in CCL . Throw diagnostic for left truncation because that is not supported
179 --- 4.2.13 2011/09/01
181 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
182 cases using escapes (\-sequences) and masking.
184 PQF parse fix: A trailing backslash followed by end-of-string (\0)
185 would result in a read one byte beyond string.
187 rpn2ccl may use Z39.50 masking for terms (t=z).
189 ICU check fix. Don't include library -lCrun on Solaris, unless present.
191 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
192 not --cppflags (which seeems like an error in icu-config).
194 --- 4.2.12 2011/08/27 RPM package only
196 cql2ccl: fix conversion of terms: operator characters were not
199 --- 4.2.11 2011/08/25 RPM package only
201 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
202 CCL parser will map both # and ? to their regular expression
203 quivalents (. and .*).
205 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
206 of reserved CQL characters.
208 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
209 is, so that they are passed through.
211 --- 4.2.10 2011/08/24
213 ZOOM SRU mode: more aggressive re-connect.
215 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
216 made available as a utility function, declared in <yaz/logrpn.h>
218 rpn2cql_structure() supports proximity nodes (except that the Type-1
219 proximity node's "exclusion" binary is ignored, as there is no way to
220 express that in CQL). Fixes bug #4564.
224 Fix SEGV that could occur if set command of zoomsh was given without
225 value (2nd argument).
227 Fix SEGV that could occur if unsupported transport was given for
228 COMSTACK - say https (when SSL was unavailable).
230 Build yaz-url on Windows too.
234 New utility to get web content. Header is url.h. A command line tool
235 yaz-url is part of the distribution and packages.
237 Fixes for SSL COMSTACK (when gnutls is in use).
239 New functions yaz_base64{encode,decode}. Header is base64.h.
243 ZOOM C includes HTTP response buffer as additional info if it fails
244 to decode the SRU response.
246 Make wrbuf_json_puts available.
250 zoom: throw diagnostic for invalid value for option "sru". Before a
251 bad SRU request was sent.
253 Adding new utility wrbuf_vp_puts.
255 Add cclxmlconfig.obj to win/makefile. It was missing completely.
259 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
260 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
261 redirect was used at the same time.
263 MARC line mode decoding: be less picky about length given - first
264 5 digits of header that is.
266 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
268 Changes to decoding of SRU records: a record with recordPacking=xml is
269 modified with a new root element <yaz_record> if the recordData contains
270 multiple children elements. This is to make the record XML parseable
273 RPN to SOLR conversion: encode special characters.
275 Generic Frontend Server: fix uinitialized member, stepSize.
279 Fix a bug in SRU decoding of records.. The database records stored
280 had un-initialized memory, but it would only be seen with yaz_record_render
281 and type_spec="ext" .
283 Fix a bug in ccl_qual_dup introduced in 4.2.3.
287 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
291 Add new utilities to convert from CQL to CCL . These utilities have
292 prefix cql_to_ccl defined in cql.h.
294 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
295 lead to memory heap corruptions when ICU utilities were in use.
299 Make compilation work without Libxml2.
301 yaz-client: remove redundant blanks in display of searchResult-1 term
306 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
307 resulting CQL node (tree) in a new node CQL_NODE_SORT.
309 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
310 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
311 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
312 Note that the CQL sortby spec is only converted when the GFS is already
313 converting from CQL to RPN (cql2rpn element).
315 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
316 specify whether to collapse delimitors or not. The existing nmem_strsplit
317 do collapse (collapse parameter = 1).
319 Windows installer: For NSIS, set InstallDir depending on x86/x64.
321 Rename internal func yaz_use_attribute_create. While non-static, this
322 function is not declared in a public header.
326 Add -lCrun when linking with ICU on Solaris.
328 More quicks character set conversions for OPAC records.
332 fix problem with record_render: records were converted (character set
333 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
337 SRU: add methods for handling DADS SRU-proxy facets.
339 Separate OPAC record character set for ZOOM_record. yaz_record_render
340 allows a character set given as charset=from/opacfrom,to where 'from' is
341 the character set of a bibliographic record, 'opacfrom' is character set
342 of OPAC record and 'to' is the target character set.
346 yaz-client: show may XML format records. Command show followed by 'format'
347 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
350 src/stemmer.c: Avoid using unnamed union. It is not supported by some
353 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
356 Update yaz.spec to operate on both SLES11 / Centos 5.5.
358 RPM: Release includes 'indexdata' name. Use indexdata in release name so
359 this package can be distinguished from other vendors.
361 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
362 as determined by configure
364 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
366 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
367 returns no error and no record, the present request is considered
368 partial (only a subset of the records could be returned by backend), and
369 so it is appropriate to set Present Status to partial-4.
373 Move yaz-config man pages to section 1.
375 More documentation about SOLR.
377 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
378 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
379 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
380 peers on some Linux systems. However, in general that does not work
381 so YAZ can not rely on that to work. Debian changed behavior in this
382 respect from Debian lenny to Debian squeeze (still testing as of Oct
384 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
386 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
390 Fix yaz-config output: echo_source not set correctly by configure.
394 SOLR WebService support for yaz-client and ZOOM.
396 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
398 --- 4.0.12 2010/08/17
400 Z39.50 facet support. Facet specifications are passed for search in
401 other-information with ASN.1 as defined in facet.asn and OID
402 .10.1000.81.5 . Facets are expressed as an Attribute list as known
403 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
404 3 is limit (number of entries to get in response). yaz-ztest returns
405 dummy facets if a client asks for them.
407 --- 4.0.11 2010/07/09
409 CCL fixes: bug 2895 and bug 3539.
411 GR1-display: add comma in display - was removed by mistake in
414 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
416 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
418 --- 4.0.10 2010/06/18
420 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
421 result set from a connection. The result set will be on its own
422 thereafter; no operations on it will perform retrievals from a target.
423 Only cached copies are returned.
425 ZOOM C:fix case for HTTP servers responding with Connection:close.
426 Ensure that if there is a current task it is resumed (like fetching
427 more records in a result set) . Bug #3484.
429 PQF parser: use odr_atoi for Odr_int (not atoi)
431 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
432 values that contain any non-digits are treated as string attributes
433 (previously decoding only checked for leading character ([0-9]). PQF
434 encoding: attribute string values are not surrounded by double-quotes.
438 New utility for managing threads - thread_create.h.
440 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
441 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
442 but YAZ' implementation do.
444 Fixes for yaz_cond-functions on Windows 7.
446 DLL export more symbols.
448 zoomsh: show record do NOT render opac.
450 Remove *.la files from Debian and RPM packages.
454 Debian package libyaz-dev depends on libgnutls-dev again (was
455 removed in YAZ 4.0.6, but due to Libtool it is still needed
456 even though yaz-config do not list libgnutls libs).
458 ZOOM: Use only one WRBUF for returning string results for
459 ZOOM_resultset. Reduces memory usage for ZOOM in general.
461 ZOOM: ZOOM_connection do not use a shared pointer to
462 ZOOM_resultset after ZOOM_resultset is destructed by
463 user. Reverts to YAZ 4.0.4 behavior.
467 record-conv: fix problem with at least one XSL conversion -
468 due to probably incorrect usage of XML XSL documents.
472 Fix yaz-config for static mode and the use of SSL (gnutls).
476 Forward decl timeval struct in mutex.h and gettimeofday.h.
478 yaz-config: fix 'static' mode linking.
482 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
483 are wrappers for pthreads or Windows. For Windows these are put in
484 a separate DLL: yaz_cond4.
486 libyaz.la (whole source) is compiled with thread. If thread support
487 is enabled enabled, all source of YAZ is compiled with treading support.
488 This allows core utilities such as yaz_log to use thread facilities.
489 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
490 thread utilities. This commit moves mutex utilities (mutex.c) from
491 libyaz_server.la to libyaz.la.
493 yaz-json-parse displays leading text until error.
497 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
498 patch from Giannis Kosmas.
500 SRU: no longer URL encode SRU database. The URL for an SRU server is
501 a URL and such is alreeady encoded - at least when given with leading
502 http:// or https://. This reverts behavior to YAZ 3.0.50.
504 Support for new MARC XML notation TurboMARC which like MARCXML is a
505 complete representation of MARC/ISO2709.. This one, however, is more
506 compact and allows for faster processing with XSLT. TurboMARC can be
507 used in the marcdisp.h API, from the yaz-marcdump utility and from
510 yaz-ztest can be configured - via the database - to perform certain
511 delays when it performs operations search, present and single record
512 fetch. This allows testers to make yaz-ztest act as a real or even slow
513 Z39.50 server. Refer to the yaz-ztest man pages for details.
517 wrbuf_destroy allows NULL WRBUF passed to it.
519 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
521 Add ZOOM_connection_close.
523 No fixed size buffers for ZOOM shell - bug #3257.
525 tstodr: make it work on s390 platform.
527 New icu iterator-functions. The new icu_iter-functions makes it possible
528 to use ICU chains from many threads.
530 yaz-client: better syntax check for show command.
534 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
537 New simple local-file XML include facility which allows file glob-patterns.
538 Refer to yaz/xml_include.h.
540 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
543 ZOOM_record_get supports new parameter "format" which makes it format XML
546 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
547 JSONText in ECMA-262) is JSONValue, not JSONObject.
551 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
552 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
554 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
555 POSIX/Unix builds .so with major version 4.
557 Remove old LOG_-defines from log.h. They have been obsolete and
558 undefined by default for the last 5 years.
560 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
562 GFS: Remove socket (int *fd) from search_rr handler. The socket
563 descriptor ptr is a facility that allowed a search handler to supply
564 a socket which would serve as a callback - when search was complete.
565 This facility has now been in use for years.
567 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
568 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
569 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
570 returns 'const char *' rather than 'char *. The returned string is
571 read-only and should not be modified by applications. COMSTACK cs_close is
572 now a void function - it no longer returns int. No applications check for
573 the value and the implementations has always returned 0.
575 ZOOM: use size_t for scan hit counts and str size. Functions
576 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
577 occ (hit count) and len (string length) are now of type size_t pointer
578 rather than int pointer. This is to be able to represent large hit counts
579 and to also just to use the proper type for string length (strlen result).
581 New JSON parser. Refer to include/yaz/json.h .
583 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
584 Used to be int in some cases. Many wrbuf_-functions used to return an int
585 indicating some length.. These return values were never used. And so they
588 ODR: odr_malloc, odr_total now takes size_t for size.
590 clone_z_type: fix leak; occurred for encoding failures.
592 --- 3.0.52 2009/12/03
594 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
595 bug was introduced in 3.0.51.
597 --- 3.0.51 2009/12/02
599 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
601 tcpip comstack: fix leak for getaddrinfo.
603 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
604 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
605 Decoding of SRU "path" database is performed by private function
606 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
607 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
609 yaz-client: honor base command for SRU. Change when database setting
610 is applied for SRU and ensure it is kept when a connection is reset.
611 Change also the way errors are displayed or SRU (decoding of packages).
613 --- 3.0.50 2009/11/02
615 Add support for extra request / response data for SRU codecs and GFS.
616 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
617 for extra data response buffer and length. For the GFS, both request
618 and response data (XML) is carried in extra_args and extra_response_data
619 for the search handler. Patch by Ko van der Sloot.
621 ZOOM: For queries that cannot be converted to the specified rpnCharset,
622 ZOOM now returns a diagnostic on the client-side ('invalid query' /
623 10010). This fixes bug #2113.
625 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
626 cmdfile included a 'quit' command that would result in a memory violation.
628 --- 3.0.49 2009/10/01
630 Make a number of functions defined in xmlquery.c static. These have
631 never been declared in a public header file (yaz/xmlquery.h) and was
632 made public by mistake.
634 Improve speed of character conversions (iconv utilities). This makes
635 conversions from MARC-8 faster.
637 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
638 unless type desired is "raw". This will prevent type "xml" from
639 returning ISO2709 .. Which obviously can not be XML parsed.
641 Fix memory leak in ZOOM that would occur if option apdulog was used
642 on a re-used connection.
644 Frontend server logs HTTP requests.
646 Frontend server now sends Z39.50 close when it times out (sesssion has
647 been idle for too long). Versions 2.0.30 and earlier also sent close.
648 But due to a mistake this was disabled in all versions after that, i.e.
649 the server would just close the socket immediately.
651 yaz-client emits a better message when receiving an unrecognised
652 userInformationField.
654 Skip zero-length subfields when decoding ISO2709. This rare case happens
655 if a record has two FS characters in a sequence. Without this patch
656 there would be a reference beyond char array in using_code_len fragments
659 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
661 --- 3.0.48 2009/08/28
663 The show command offered by the zoomsh command now takes a 3d optional
664 parameter type which is what is passed to ZOOM_record. If the type
665 argument is omitted, "render" is used.
667 RPN to CQL conv may use USE string attributes (bug #2978).
669 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
671 --- 3.0.47 2009/07/08
673 Function yaz_xml2query allows a diagnostic element in the PQF XML
674 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
675 code and additional info respectively.
677 The BER BOOLEAN is now the integral type Odr_bool which still happens
678 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
679 typedef'd to Odr_int. This is still an integral 'int', but it may be
680 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
681 ASN-1 compiler as well as programs has been updated to use the new types.
683 --- 3.0.46 2009/06/08
685 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
686 only the bibliographic record was rendered. For type=opac, an OPAC
687 record is only returned if it is present.
689 iconv: small fix for encoding of advancegreek.
691 yaz-client: avoid double display of SRU/SRW records (bug #2798).
693 yaz-client: option auto_reconnect=on really reconnects.
695 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
697 server: avoid null ptr ref for for yaz_poll errors.
699 build: fix RPM build for RHEL 5.3.
701 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
703 --- 3.0.45 2009/03/31
705 Fixed bug #2709: TCP connect returns Invalid argument.
707 Fixed compilation for mingw.
709 Honor charset for raw records (ZOOM_record_get).
711 Fixed use of errno for threaded mode that was seen on Solaris 10.
713 Fixed argument passing with blanks in value for Windows Service.
715 Disable YAZ' own log rotate by default (no 1 GB limit).
716 The variable l_max_size which specifies the log file limit is set to 0
717 (DISABLED): This is due to the fact that YAZ is most often deployed using
718 logrotate. Also YAZ can not perform log rotate because of unsufficient
719 permissions (setuid).
721 --- 3.0.44 2009/02/17
723 List supported encodings in man page for yaz-iconv.
725 Fixed missing SSL libs for --libs output
727 Re-established OID record syntax application-xml. Nobody should use it
728 but we don't want to change soname because of this symbol being absent.
730 --- 3.0.42 2009/02/02
732 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
734 Added member named_result_sets for init handler struct for the GFS. This
735 allows a server to disable named result sets.
737 Removed OID record syntax application-xml.
739 Added support for rule-based transliterator for ICU wrapper of YAZ.
741 Fixed bug #1902: yaz-icu XML output.
743 Make YAZ checks Emacs friendly.
745 BITSTRING value shows value. Bug #2346.
747 ISO2709 decoding: skip control characters from indicator data.
749 Omit sort key by default in yaz-icu's output.
751 Allow combined single char options (again) for YAZ' options function.
753 Utility yaz-marcdump got option to display YAZ version (-V).
755 Allow YAZ to use ICU 3.4.
757 Added new ICU test case which illustrates removal of diacritics.
759 --- 3.0.41 2008/12/29
761 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
763 --- 3.0.40 2008/12/29
765 For configure, using option --without-xml2 also disables Libxslt/Libexslt
768 Fixed bug #2352: yaz-marcdump crashes for certain record.
770 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
772 Added support for Danmarc2 to UTF-8 conversion.
774 Added support for ISO5426 to UTF-8 conversion.
776 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
777 implementation version.
779 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
781 --- 3.0.38 2008/11/10
783 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
784 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
786 ZOOM C now interprets databaseName option for ZOOM connection as path
789 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
791 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
793 Dummy Libxml2 types no longer defined in headers of YAZ'.
795 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
798 --- 3.0.36 2008/09/26
800 Various ODR chapter fixes.
802 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
804 Added missing source for Windows compilation, mutex.c.
806 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
808 For SRU connections in ZOOM all records up to "count" are now fetched.
810 Fixed crash in generic frontend server (and yaz-ztest) which occurred
811 in Windows due to bad error handling for Libxml2.
813 Added facility for sending arbitrary records (ASN.1 any) using
814 ZOOM C's Extended service update. Patch by Sam Reynolds.
816 New options for ZOOM C's connection, logapdu which makes ZOOM log
819 --- 3.0.34 2008/06/18
821 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
823 --- 3.0.32 2008/06/12
825 Fixed memory violation that could occur when decoding UTF-8. This bug
826 was only present in 3.0.30 of YAZ.
828 --- 3.0.30 2008/06/06
830 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
831 GNU TLS is used by default (if found).
833 yaz-ztest returns OPAC records if a client asks for OPAC.
835 Improved speed of MARC-8 encoding.
837 Added support for lossy and loss-less MARC-8 encoding.
839 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
841 Added new Windows Service wrapper (sc).
843 yaz-client's itemorder command may now send a file.
845 Fixed yaz-marcdump to allow the use of NS prefix for record element.
847 Added new function yaz_log_xml_errors.
849 Allow (but warn) unknown XML attributes in MARCXML parsing.
851 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
853 The UTF-8 to MARC-8 conversion now uses a different set of characters
854 for Greek symbols. Bug #2120.
856 --- 3.0.26 2008/02/21
858 Added yaz_daemon (daemon.h).
860 Fixed bug #2068: pkg-config trouble
862 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
864 --- 3.0.24 2008/01/28
866 Document --with-xml2 option.
868 Added OPAC XML XSD (etc/opacxml.xsd).
870 Allow glob mask for name attribute in retrieval element for the
871 generic frontend server's retrieval facility.
873 Changed yaz_poll_poll to return yaz_poll_except for all returned events
874 except POLLIN/POLLOUT.
876 Fixed error handling in cs_listen. Bug #2037.
878 --- 3.0.22 2008/01/20
880 Fixed version in yaz/yaz-version.h.
882 Fixed bug #2027: Crash when closing connection.
884 Changed configure so that ICU support is only enabled if only ICU
885 and Libxml2 is available (because the ICU chain is XML based).
887 --- 3.0.20 2008/01/15
889 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
890 is built. Only this DLL depends on the ICU runtime.
892 yaz-ziffy is no longer part of YAZ. It is distributed separately by
893 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
895 Changed license of CCL module to 'Revised BSD'. After consultation with
896 remaining members of the original EUROPAGATE consortium, we are re-issuing
897 the CCL module without a separate license. The software was developed by
898 Index Data as part of a research project. The special license was included
899 to help feed usage information back to the project consortium to support
900 project evaluation. At this time, the project consortium has long-since
901 disbanded, and the majority of the original principals have retired. At the
902 same time, we have significantly modified the software during the following
903 years, to the point where very practically no original code remains. To
904 simplify re-use of the software, we have contacted those members of the
905 consortium who could be reached, and agreed to re-issue the module as a
906 proper part of the YAZ package.
908 Tcl scripts uses /usr/bin/tclsh as preferred shell.
910 CQL closer to being version 1.2 compliant. CQL also allows free-form
911 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
914 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
915 bug could make Extended services handling crash in the ZOOM layer. This
916 bug was only present in YAZ 3.0.18.
918 --- 3.0.18 2007/12/19
920 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
923 yaz-marcdump reads and writes collection wrapped records.
925 Handle OPAC for record conversion module.
927 Fixes for ICU wrapper.
929 Allow ICU libs to be controlled with --with-icu .
931 --- 3.0.16 2007/11/12
933 Added yaz_poll which is a wrapper for select/poll. When poll is available
934 and non-buggy, it is used, by yaz_poll . This allows more than 1024
935 sockets to be in use.
937 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
938 functionality through an XML based configuration (ICU chain). This system
939 is useful for search facilities such as Pazpar2 and Zebra that needs to
940 perform tokenization of indexed material. The ICU code in a separate
941 library libyaz3_icu.a.
943 Added HTTP tunnel facility for COMSTACK, bug #1752.
944 This is a facility that allows a Web proxy, such as squid, to tunnel
945 Z39.50 traffic. This facility is "transparent" to must applications
946 using YAZ. It's enabled by using pseudo transport connect: followed by
947 the proxy address, followed by command, then follwed by he regular
948 "virtual" addresss. For example,
949 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
951 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
953 --- 3.0.14 2007/09/21
955 Fixed bad memory reference in ZOOM_record - cuased by member not being
956 initialized. This was a problem only in YAZ 3.0.12.
958 Fixed bug in conversion from MARC to XML: Non-XML characters in control
959 fields were not removed.
961 Changed the way C code is generated from codetables.xml. Made a MARC-8
962 conversion trie for each characterSet section rather than codeTable.
963 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
964 of codetables.xml from Larry Dixson, LOC. Bug #1464.
966 --- 3.0.12 2007/09/12
968 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
969 from ZOOM_record_error).
971 ZOOM C function ZOOM_record_get returns record schema for type="schema".
973 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
975 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
977 Better SRW-to-Bib-1 diagnostic mapping.
979 ZOOM C and yaz-client announces SRU version 1.2 by default.
981 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
984 Fixed in yaz_sru_decode to allow other version than 1.1.
986 --- 3.0.10 2007/08/22
988 Added support for SRU scan for ZOOM.
990 Added support for the use of the older versions or Extended Service
991 Update in ZOOM. To faciliate this, an option "updateVersion" may be
992 set to the version , 1=first, 2=second, 3=third. The third version is
993 what ZOOM C has used so far. And that, obviously, is the default.
995 Added support for CCL queries in Z39.50 queries sent to the GFS (and
996 therefore in Zebra and in SimpleServer-based applications). The new
997 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
998 qualifier file used to transform incoming CCL queries into Type-1 RPN,
999 which is passed into the back-end search callback function.
1001 Added support for HTTP Basic authentication in clients: the SRU/W
1002 codec encodes the username/password elements of the PDU structure
1003 appropriately, and these may be set using the "user" and "password"
1004 options in ZOOM-C applications (the same options that are used for
1005 Z39.50 authentication).
1007 --- 3.0.8 2007/06/25
1009 Fixed bug #1208: SSL appears to be broken in ZOOM.
1011 Fixed bug #1206: Libxml2 include path weirdness.
1013 Added oid_name_to_dotstring.
1015 Allow elementSetName to be specified for ZOOM C record update.
1017 Allow waitAction to be specified for ZOOM C based for Extended Services.
1019 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1020 syntax OID. Bug introduced in YAZ 3 series.
1022 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1024 --- 3.0.6 2007/06/06
1026 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1027 directory. yaz-client now reads commands from file given by option -f
1028 if specified; then tries to read .yazclientrc in current directory.
1029 Failing that, it reads .yazclientrc from user's home directory.
1031 Added support for correlationInfo Note and ID for Record Update via
1034 Added yaz-client command querycharset which specifies character set for
1035 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1036 (termListAndStartPoint).
1038 Charset ISO5428:1984 is an alias for ISO5428-1984.
1040 Implemented a way to perform scan in a result set using Z39.50. This
1041 is achieved by attaching the result set name in the characterInfo
1042 (type InternationalString) of OtherInformation in the Scan Request PDU.
1043 The result set is identified in the otherinformation by the new OID:
1044 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1045 This allows for scan in result set and faceted search . Zebra did some
1046 of this in the APT term using attribute type 8 and value being result
1047 set. Using the OtherInformation approach for this is cleaner and easier
1048 to work with in proxies and the like. This facility can be used in
1049 yaz-client using new command setscan which takes a result set as first
1050 argument, start position (APT) as second.
1052 Changed decoding of SRU XML packed records to deal with servers that
1053 have recordData with XML data with multiple root nodes. Also make
1054 comparison for recordPacking case insensitive. Again, one server
1055 returns "XML" where others return "xml".
1057 For SRU responses allow Content-Type application/xml as well as text/xml.
1059 --- 3.0.4 2007/05/21
1061 Fixed bug in character set conversion of BER strings. Bug introduced
1064 --- 3.0.2 2007/05/08
1066 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1068 For OID class, use oid_class consistently.
1070 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1073 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1074 character set for bibliographic information interchange". By Giannis Kosmas.
1076 Added documentation on new OID API.
1078 --- 3.0.0 2007/05/02
1080 Changes to generic frontend server interface: added new member
1081 'query_charset' for bend_initrequest structure. A backend init handler
1082 should set this member to its native character set for query terms.
1083 When defined, the frontend server logic will announce this character set
1084 to a client if the negotiationModel bit is set by the client. All server
1085 implementors are encouraged to specify this. If a backend server does not
1086 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1088 Added CCL utility to remove terms (stop words) from resulting RPN
1089 tree. This is handled by functions with prefix ccl_stop_words_ .
1091 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1092 terms in RPN queries.
1094 Clean-up the CCL API. Moved some internal structures from ccl.h to
1095 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1096 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1097 This is replaced by ccl_parser_find_str which takes a string instead.
1099 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1100 libyaz.la is the core of YAZ except the generic frontend server and
1101 does not depend on POSIX threads anymore. libyaz_server.la is the
1102 generic frontend server facilities and uses POSIX thread functionality
1103 if available. The libyaz.la no longer depends on POSIX threads because
1104 the number of global structures is limited. NMEM no longer re-uses blocks
1105 between threads ; it simply free's memory immediately but allocates in
1106 "large" chunks as usual. We don't expect any performance penalties
1107 because of this. The yaz_log system is still using a global log_level so
1108 caution must be taken when modifying it with yaz_log_init_.. +
1109 yaz_log_mask_str. This, however, should not cause any trouble because
1110 these functions are called during initialization of application code
1111 anyway. `yaz-config --libs server` returns libs for server applications;
1112 `yaz-config --libs` returns libs for non-server applications.
1114 New OID database - with public definitions in oid_db.h. Removed old OID
1115 database including the head oid.h and definitions such as enum oid_value
1116 and struct oident. The new OID database uses the same string names as
1117 before but the 'protocol' is gone. There are now only two representations
1118 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1119 converts from string to OID; functions with prefix yaz_oid_to_string
1120 converts the other way.
1122 Change to emit_term() in CQL-to-PQF query translation: when a term has
1123 the /regexp relation modifier, do not process it for leading and
1124 trailing "^" and "*", which have quite different meanings in regular
1127 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1128 write handlers no longer carries a 'last' parameter. This will make
1129 yaz_iconv flush "less" characters. A flush is performed by call to
1130 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1132 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1133 removed, because function yaz_query_to_wrbuf does the same.
1135 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1136 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1138 Deprecated MARC utility functions removed.
1140 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1143 Branch split: YAZ_2_1_55_branch
1145 --- 2.1.54 2007/03/16
1147 Fix to ZOOM-C so that transparent reconnection is properly handled on
1148 connections that are in asynchronous mode.
1150 Fixed compilation on OpenBSD 4.0.
1152 Large strings in GRS-1 records are now properly displayed in yaz-client.
1154 Added character conversion support for "advancegreek"; based on patch from
1157 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1158 sequence is met. Before the error was not set so it would be unknown.
1160 Adjust yaz-marcdump MARC reader so that it skips until record separator
1163 --- 2.1.52 2007/03/07
1165 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1166 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1167 fd_set structure used as a bitmask for the FDs to be selected on.
1169 Using ACX_PTHREAD macro to check for POSIX threads.
1171 Fixed have-vsnprintf check.
1173 --- 2.1.50 2007/02/23
1175 Fixes for configure on BSD. Bug #900.
1177 Added snprintf/vsnprintf wrappers for systems that don't have
1178 limits (heavens forbid).
1180 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1181 created before all previous tasks were completed and removed from the
1182 task queue, the new task could be removed by a mistake.
1184 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1186 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1188 Fixed bug #832: Problem with MARC/charset in yaz-client.
1190 Fixed bug #668: save command line history for yaz-client.
1192 Fixed bug #830: pkg-config support.
1194 --- 2.1.48 2007/01/23
1196 Extended ZOOM result set options with two options that may be read by
1197 a client: resultSetStatus and presentStatus with values as specified for
1199 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1201 Fixed bug #827: Using SSL fails on Debian etch.
1203 Fixed bug #826: Weird looking chars for set of MARC records.
1205 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1206 that is treated as an ItemOrder with itemRequest being an XML document
1207 external. The value of "doc" is the content.
1209 Extended the GFS search facility. New member of bend_search_rr
1210 'estimated_hit_count' signals that hits is known to be an estmate
1211 (higher or lower than real hit count). New member 'partial_resultset'
1212 signals that the search was partial (hit count is lower or equal than
1213 real hit count). For Z39.50, the information is stored in resultSetStatus
1214 member of SearchResponse APDU. For SRU, the information is signalled
1215 via SRU diagnostic 59: "Result set created with valid partial results
1218 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1220 --- 2.1.46 2007/01/13
1222 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1224 Added ZOOM_connection_peek_event.
1226 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1227 the following new functions:
1228 ZOOM_event_nonblock, ZOOM_connection_process,
1229 ZOOM_connection_get_{socket,mask,timeout},
1230 ZOOM_connection_fire_event_{timeout,socket}.
1231 The existing blocking event handler, ZOOM_event, is a wrapper for the
1232 + blocking ZOOM_event_sys_{poll,select}.
1234 Implemented function ccl_xml_config which parses XML version of CCL
1235 configuration (bug #798).
1237 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1239 Added timings utility (yaz/timing.h)
1241 --- 2.1.44 2007/01/03
1243 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1246 Fixed bug #779: Rotation of apdu.log fails.
1248 Fixed for character set conversions:
1249 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1250 Honor G1 set in MARC-8 decoding.
1252 --- 2.1.42 2006/12/17
1254 Fixed bug #775: char conversion does not handle Alternative UTF-8
1257 Implemented function yaz_marc_read_line which parses MARC line format
1258 records. There is a wealth of formats out there. So far, this function
1259 reads line records produced by yaz_marc_write_line.
1261 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1262 more generic and easier to remember(!) options: -i format and -o format
1263 which specifies input format and output format respectively - where
1264 format is one of "marc", "marcxml", "line", "marcxchange".
1266 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1267 does not print anything except warnings for records.
1269 For yaz-marcdump, added support for MARC split into files (-s) with a given
1272 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1273 spec, at http://www.loc.gov/standards/sru/record-update/
1274 This has changed the binary layout of the following structs:
1275 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1276 bend_update_rr . Patch by Ko van der Sloot.
1278 Added GFS utility function bend_assoc_is_alive which returns 1 if
1279 association is still alive (client is connected); 0 otherwise (client
1280 closed connection). This allows busy servers to stop working for
1283 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1284 been a separate piece of software. This version of ziffy has been modified
1285 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1287 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1289 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1290 Client code may now interrogate options such as "init_opt_sort" to
1291 find out whether the server claims to support various options.
1293 --- 2.1.40 2006/11/27
1295 Added utilities yaz_{set,get}_esn to set/get element set name from
1298 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1299 of YAZ and has been so since YAZ 2.1.10.
1301 Implemented ZOOM_record_error which returns error information for
1302 record (surrogate diagnostic).
1304 --- 2.1.38 2006/10/31
1306 Updates for SRU Update by Ko van der Sloot:
1307 1. Changed name from "operation" to "action"
1308 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1309 versions in the code, marked as 'backward compatible'.
1310 3. Added diagnostics for SRU Update.
1312 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1314 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1316 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1318 For GFS, fixed problem with SRU diagnostic 'First record position out of
1319 range' being issued for 0 hits.
1321 zoomtst10 part of Windows Build.
1323 --- 2.1.36 2006/10/13
1325 Implemented yaz_filepath_comp which splits a path into file path
1326 components (required by Zebra 2.0.3+).
1328 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1329 BSD inspired license until now so this should not have any real impact on
1330 anybody. See http://www.opensource.org/licenses/bsd-license.php
1332 Fixed bug #687: Missing log lines.
1334 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1337 Fixed bug #689: SRU diagnostics to be added.
1339 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1340 whether a connection is idle (no more work do do).
1342 --- 2.1.34 2006/10/04
1344 Change type of optval from long to int for invocation of setsockopt with
1345 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1347 Added support for specifying the max log file size for the Generic
1348 Frontend Server. The size is given with option -r.
1350 --- 2.1.32 2006/09/21
1352 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1354 --- 2.1.30 2006/09/17
1356 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1359 Fixed bug in Generic Frontend Server that could cause a server to stop
1360 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1362 For the generic frontend server, the maximum record size is used as maximum
1363 size of incoming packages (SRU + Z39.50). The value until was previously
1364 only used in Z39.50 Init negotiation and, later, in a session controlled
1365 sizes of records returned. This is controlled using -k option. It can be
1366 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1368 --- 2.1.28 2006/09/04
1370 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1373 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1375 New option for yaz-marcdump -lpos=value which allows setting a portion
1376 of MARC header to a certain value.
1378 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1380 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1381 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1383 --- 2.1.26 2006/08/15
1385 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1388 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1390 --- 2.1.24 2006/08/08
1392 Fixed MARC ISO2709 encoding routines to deal with character set
1395 Minor changes to GFS logging. Database included in search request log
1398 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1399 cached/multiple records.
1401 Shared libraries are built by default on Unix+configure.
1403 Changed cql2pqf transformation to use a different evaluation order. The
1404 new order is: always, relation, structure, position, truncation, index
1405 and relationModifier. Old order was: always, relation, relationModifier,
1406 structure, index, position, truncation. Note that the the latter ones
1407 override former ones for identical attributes.. The new scheme means that
1408 it is possible to override any existing attribute with a relationModifier.
1409 And also that it is possible to override everything for the index rule
1410 (except the ones listed in relationModifier). No order is perfect but this
1411 one, we believe, covers more real cases.. The "always" should have been
1412 called "default", since the attributes there can be overridden with all
1415 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1416 compilation phase, but also for yaz-config --cflags output. This allows
1417 us to have public headers with Libxml2 stuff in them . It should also,
1418 eventually, make Libxml2 checks redundant in packages using YAZ, such
1421 --- 2.1.22 2006/06/15
1423 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1424 stored in uri, message and details.. Previously diagnostics were stored
1425 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1426 compatibility.. but he's probably the only one affected, so.
1428 Added support for CCL, compiled on the client side, in ZOOM-C. This
1429 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1430 input; the resulting query objects can be used for for searching with
1431 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1433 YAZ' configure searches for OpenSSL by default.
1435 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1436 SL_CTX_use_certificate_file. See
1437 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1438 for more info. Thanks to Ko van der Sloot.
1440 --- 2.1.20 2006/06/02
1442 Bug #600: SRU GET, POST support for yaz-client. Introduced
1443 command 'sru' which selects method SOAP/GET/POST.
1445 Allow missingValueAction to be specified for the sortspec string -
1446 function yaz_sort_spec. By default, the missing value action is null.
1447 Use ! to specify "abort". Use = followed by stringvalue to specify default
1450 Ensured that Present-handler (if defined) is called in GFS before any call to
1451 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1452 searchRetrieve requests.
1454 Documentation for YAZ is now based on the Docbook XML/XSLT using
1455 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1456 is no longer depending on jade/openjade or docbook-to-man scripts.
1457 PDF is no longer part of the distribution - but can optionally be
1458 made using DSSSL/jadetex or FOP.
1460 Added retrieval handling support in Generic Frontend Server to support
1461 conversion between MARC/XML as well as XSLTtransforms. See
1462 etc/yazgfs.xml for an example.
1464 Added Authentication support to Generic Frontend Server in SRU
1465 mode. Authentication using HTTP Basic is supported, as is the use
1466 of 'x-username' and 'x-password' parameters in the request itself.
1468 Added support for a new character set MARC8s identical to MARC8 except
1469 that it converts combined characters to single Unicode characters in the
1470 Latin-1 range (when possible).
1472 --- 2.1.18 2006/04/24
1474 ASN.1 compiler 0.4: generates brief Doxygen file header for
1475 generated .h/.c files.
1477 Utility yaz_iconv now supports conversion to MARC-8.
1479 New facilities for the MARC module. The reading - and writing of
1480 content are separate methods for the yaz_marc_t handle. The following
1481 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1482 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1483 format). Write functions have prefix yaz_marc_write_.. The existing
1484 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1485 available. Removed support for OAI-MARC and simplexml (not the
1486 simplexml from PHP5).
1488 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1489 to be returned for this connection.
1491 --- 2.1.16 2006/03/31
1493 Allow multiple languages and charsets to be specified with
1494 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1495 negcharset iso-8859-1,utf-8
1497 Translation of proximity nodes from CQL into PQF now works.
1499 Moved to automake 1.8, 1.9.
1501 Added function yaz_log_set_handler which allows a log handler to be
1502 installed. This handler will be called for all log messages. Output
1503 to file is also produced; but that can be disabled by passing NULL
1504 fname to yaz_log_init_file.
1506 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1508 For SRW (including GFS), accept application/soap+xml as content-type
1511 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1512 produces NO stylesheet reference even if a default stylesheet is specified
1515 --- 2.1.14 2006/03/14
1517 Updated Windows package to include yazd.dll + yazd.lib for the
1518 Development component.
1520 If the environment variable YAZ_LOG is set, then it is used as a
1521 string indicating the default level of logging to use if not
1522 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1523 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1524 used as before. So, for example, to omit warnings from YAZ logging,
1525 export YAZ_LOG=-warn
1527 cql_transform() now map structure and other attributes before indexes,
1528 so that index-specific structures and other attributes can override
1529 defaults. So now a combination of mapping specifications such as:
1531 index.dc.date = 1=date-modified 4=5
1532 does the right thing.
1534 cql_transform() now also respects the "always" mapping specification,
1535 which establishes an initial set of attributes to be used for all
1536 terms except where overridden by more specific attributes associated
1537 with the index, relation or modifier.
1539 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1540 which mode to use; one of "post", "get" or "soap" (SRW, default).
1542 Fixes for yaz_iconv routines: changed trie-based character set conversions
1543 to use only non-negative values for bit fields due to Sun's C compiler not
1544 supporting negative values.
1546 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1547 sequences where not read correctly. Fix by Rustam Usmanov.
1549 Updated win/makefile to use options, settings which makes things
1550 compile with VS C 2005.
1552 --- 2.1.12 2006/02/01
1554 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1556 In ZOOM socket code, use select instead of poll on MacOSX.
1558 ZOOM-C now support client-side compilation of CQL into RPN that is
1559 sent to the server, enabling CQL to be used against all Z39.50
1560 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1561 ZOOM_query object, and submit it using ZOOM_connection_search().
1562 The CQL-to-RPN translation uses a configuration file, the name of
1563 which must be specified in the Connection's "cqlfile" option.
1565 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1566 function, which takes as its start-term parameter a ZOOM_query object
1567 (which may have had either CQL or RPN set into it).
1570 --- 2.1.10 2005/11/29
1572 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1573 GFS to support this as well. Backend handler, bend_srw_update, does the
1574 update work. Code contributed by Ko van der Sloot.
1576 Allow retrieval of Search Result-1 information in ZOOM by the use of
1577 options that are attached to a result set. ZOOM documentation updated
1580 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1581 UTF-8 conversion. Patch by Raj Patel.
1583 Added option -m to GFS to control formatting of timestamps in log file.
1585 Added 'exit' as synonym for 'quit' in yaz-client
1587 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1588 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1589 for the new members. Patch by Ko van der Sloot.
1591 Added support for SRU POST. It is supported for content-type
1592 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1594 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1595 Instead make the library libyaz.la multi-threaded. Threading as a whole
1596 can still be disabled by configure option --disable-threads. Previosly,
1597 with older GLIBCs there were problems with MT libs under Apache. This
1598 has now been fixed a long time ago.
1600 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1603 CQL module modified to be case insensitive for relations/indexes/operations.
1605 Fixed bug in CQL transform code: incorrect value relationModifieder
1608 Added 'show all' command for yaz-client which retrieves all results
1611 Added new yaz-client, xmles, which takes a (private) OID and
1612 a document to be sent as an extended service request.
1614 Describe new yaz-client commands wait_response and set_auto_wait.
1616 Increase TCP/IP listener backlog from 3 (which I am guessing was
1617 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1618 that the socket will queue as many incoming connections as it's able
1619 to handle ongoing connections. In other words, it will never now
1620 refuse a connection that it would be able to handle merely because
1621 it's not got around to accepting() enough of the pending connections
1622 yet. This is the behaviour anyway under Linux, where the listen()
1623 argument is ignored; but not under BSD and on systems such as
1624 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1625 YAZ-based servers should now be uniform across operating systems in
1628 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1629 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1630 This allows yaz-marcdump to read large MARC batches (>2 GB).
1632 Modified all YAZ source files - except the source which is auto-generated
1633 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1636 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1637 corresponding to the existing *_setl() function. These allow option
1638 values containing arbitrary valuues.
1640 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1641 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1642 except that it returns an indicator of whether or not the sort
1643 criterion was accepted (0 for OK, -1 for invalid).
1645 --- 2.1.8 2005/06/07
1647 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1648 MARC output rather than returning "new" buffer.
1650 yaz-client warns about unknown init options.
1652 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1654 --- 2.1.6 2005/05/24
1656 Added support for SRW sort in Generic Frontend Server. Patch
1657 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1658 sortKeys - or NULL if none is provided.
1660 Fixed bug #307: It was impossible to specify indefinite/no timeout
1661 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1664 Added support for multiple languages and charsets to be specified in
1665 ZOOM. Each charset/language is separated by a blank. If negotiation is
1666 in effect in init-response, Option
1667 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1668 Code based on patch by Vasiliy Osadchuk.
1670 Fixed bug #306: infinite recursion that occurred when calling
1671 yaz_log_level_init as the first call (before other log level or
1674 Fixed bug in scan handling in front end server: if preferred-Position-In-
1675 Response was non-present, a NULL pointer referece was performed.
1677 --- 2.1.4 2005/04/26
1679 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1680 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1681 now defined for all those error codes. So instead of putting 109 in
1682 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1683 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1685 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1688 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1690 Program yaz-client now exits and produces an error message if multiple
1691 Z39.50 servers are specified on the command line (none or one allowed
1694 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1697 --- 2.1.2 2005/03/16
1699 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1701 Fixed bug #272: Preserve spacing for CCL terms.
1703 --- 2.1.0 2005/03/14
1705 Added support for virtual hosts and multiple backend servers for
1706 the YAZ frontend server. The configution is XML based and
1707 support specificition of CQL to RPN mappings and explain information.
1708 See section "Virtual Hosts" in the YAZ manual.
1710 Extended OPAC display utility. OPAC display utility renders
1711 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1712 to supplement yaz_marc_decode_wrbuf.
1714 Fixed a bug in MARC decoder that could caused it to crash for some
1715 invalid MARC records. More diagnostics and warnings where added in
1716 XML output (warnings, etc are stored in comments).
1718 --- 2.0.34 2005/02/08
1720 Fixes for UNIX domain sockets. Bug #261.
1722 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1724 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1725 Added yaz_marc_subfield_str which defines subfield lead string which is
1726 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1727 yaz_marc_endline_str which defines end of fields string used in
1728 YAZ_MARC_LINE format. Default string is newline.
1730 Experimental support for MarcXChange. This format can be produced
1731 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1732 http://www.bs.dk/standards/MarcXchange.xsd
1734 Added yaz-client commands scansize that sets maximum number of
1735 entries to be returned by scan.
1737 --- 2.0.32 2005/01/11
1739 Added support for SRW scan in yaz-client and Generic Frontend Server.
1741 * Added whereInList member to SRW Scan Term.
1743 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1745 Fixed NMEM system to return aligned blocks on the smallest boundaries
1746 that are suitably aligned for all possible types on the particular
1747 architecture YAZ is being built for.
1749 --- 2.0.30 2005/01/04
1751 Fixed numerious warnings that was issued with newer versions of GCC.
1753 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1754 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1757 Make YAZ Generic Frontend Server slightly faster.
1759 Enhance (and reduce) logging for Generic Frontend Server.
1761 Revert YAZ log system so that it flushes every write operation
1762 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1764 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1765 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1766 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1767 will effectively disable old definitions.
1769 --- 2.0.28 2004/11/09
1771 Added yaz_log_time_format which specifies log format using
1774 Added yaz_log_module_level which returns mask for a module. Value
1775 is non-zero mask a if module is enabled; zero if disabled.
1777 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1778 in include/yaz/cql.h.
1780 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1782 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1784 Fixed bug #172: RPM builds does not enable SSL.
1786 Doxyfile.in part of dist. Doxyfile generated by configure.
1788 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1789 are given and the corresponding component does not exist.
1791 Extend CCL documentation in YAZ reference. Describe r=r.
1793 --- 2.0.26 2004/10/01
1795 Fixed MARC->MARCXML conversion to properly deal with
1796 fields, subfields, indicators having non-ASCII characters.
1798 Fixed MARC->MARCXML conversion so that ASCII control characters
1799 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1802 Added YAZ GFS support for conversion from Z39.50 surrogate
1803 diagnostics to SRW surrogate diagnostics.
1805 Bug fix: YAZ GFS did not return schema in explainResponse.
1807 --- 2.0.25 2004/09/30
1809 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1810 now converts recordSchema to elementSetName as well as schema URI.
1812 Fixed bug in COMSTACK that prevented HTTP request packages from being
1815 --- 2.0.24 2004/09/29
1817 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1818 does not require white-space before and after the dash in a range, e.g.
1819 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1822 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1823 due to new GCC removing "redundant" code.
1825 Added yaz-client commands scanpos and scanstep that sets preferred
1826 position and step-size for scan.
1828 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1830 Added CCL utility ccl_qual_buf which parses one or more CCL
1831 spec lines in a buffer.
1833 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1834 of name and value - ignoring empty lines and comments.
1836 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1838 Added odr_get_element_path which returns current element path for an
1839 ODR handle. This utility is useful in error handling or user-defined
1842 Added ODR_PRINT utility odr_set_stream which is is a more generic
1843 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1844 to a write function and pointer to close function. The close function - if
1845 non-NULL - will be called during odr_destroy.
1847 Fixed bug in CCL parser where truncation char was not removed from
1848 right side when truncation=both was in effect.
1850 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1853 --- 2.0.23 2004/08/11
1855 Fix buffer overrun in CQL parser when dealing with proximity (%).
1857 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1858 to UTF-8/UCS conversion is now only based on codetables.xml.
1860 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1862 --- 2.0.22 2004/08/06
1864 Add support for more "commit changes" in ZOOM (uses Extended Services).
1866 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1869 Yet another small fix for configure of SSL.
1871 --- 2.0.21 2004/05/14
1873 Fix SSL libs for configure when --with-openssl=DIR is given.
1875 --- 2.0.20 2004/05/10
1877 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1879 SSL comstack now uses yaz.pem certificate file on server side
1880 by default. Certificate filename can be configured by calling
1881 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1883 Fix bug regarding multiple calls to ZOOM_connection_connect.
1885 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1887 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1888 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1890 ZOOM now allows inspection of X509 peer certificate for verification.
1891 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1893 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1894 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1895 as "modular" but it simplifies things.
1897 Added cs_get_peer_certificate to that returns peer X509 PEM.
1899 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1900 NULL if SSL is unavailable.
1902 Documentation about MARC decoding tools.
1904 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1906 --- 2.0.19 2004/03/30
1908 Rename CHANGELOG to NEWS to follow GNU style packing.
1910 Fix bug with missing initialization of member in init_diagnostics.
1911 This bug affects threaded version of GFS server.
1913 --- 2.0.18 2004/03/20
1915 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1918 Ensure zlib.dll is packed with Windows install.
1920 --- 2.0.17 2004/03/17
1922 Fix encoding of xsd:string to use text instead of CDATA.
1924 Fix endless loop in CQL parser with unbalanced ".
1926 Use a more compact way to store MARC-8 conversion tables.
1928 --- 2.0.16 2004/03/16 Debian only
1930 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1933 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1938 --- 2.0.15 2004/03/01
1940 Another fix for decoding of XML packed records.
1942 --- 2.0.14 2004/02/25
1944 Fixes for Chunked encoding. White space not ignored after length spec.
1946 Update NS and use default NS for SRW diagnostic elements.
1948 --- 2.0.13 2004/02/23
1950 Implement ZOOM_resultset_cache_reset which resets record cache.
1952 Implement ZOOM_resultset_sort which sorts a result set.
1954 Implement chunked HTTP transfer.
1956 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1958 --- 2.0.12 2004/02/16
1960 Added member 'schema' to bend_explain_rr structure so that backend
1961 can specify explain record identifier. Defaults to Zeerex 2.0.
1963 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1965 --- 2.0.11 2004/02/16
1967 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1970 Added init command for yaz-client which sends "extra" init request.
1972 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1973 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1975 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1977 Make ZOOM error code for "invalid query".
1979 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1981 --- 2.0.10 2004/02/05
1983 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1986 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1988 Added option -p <file> to make Generic Frontend Server to write PID file.
1990 Added option -D to put Generic Frontend Server in background on its own.
1992 Make ZOOM C recognize option "password". If unset, "pass" is used
1993 (for backwards compatibility).
1995 Fixed a bug in Generic Frontend Server that could make it crash if a
1996 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1999 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2000 Must be issued before open, in order to be in effect.
2002 --- 2.0.9-6 2004/01/12 Debian/Windows
2004 Make the SRU server more picky WRT unknown params, etc.
2006 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2008 New YAZ client command, options, that sets Z39.50 options.
2010 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2011 options from a string of tokens (one token for each option bit).
2013 Update SRW diagnostic code messages.
2015 --- 2.0.9-5 2004/01/07 Debian/Windows
2017 Handle user defined stylesheet for SRW/SRU.
2019 --- 2.0.9-4 2004/01/06 Debian/Windows
2021 Fix bug in decoding of Content-Length.
2023 --- 2.0.9-3 2004/01/06 Debian/Windows
2025 Fix a bug with decoding of XML packed records.
2027 --- 2.0.9-2 2004/01/05 Debian only
2029 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2031 Fix bug in SRW/SRU diagnostics decoding.
2033 --- 2.0.9 2004/01/05
2035 Fixed bug in Generic Frontend Server which could drop records exceeding
2036 preferred message size. Reported and fixed by Irina Dijour.
2038 Fixed calculation of package size for structured records in Generic
2039 Frontend Server. Reported and fixed by Irina Dijour.
2041 Fixed namespace for SRW/SRU diagnostics.
2043 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2045 --- 2.0.8 2003/12/22
2047 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2048 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2051 CQL changes to reflect recent changes to the specification:
2052 * Documentation talks about context sets instead of index sets.
2053 * Documentation talks about indexes instead of qualifiers.
2054 * The CQL-to-PQF transformer's configuration file now uses
2055 "index.set.name = <attributes>" instead of the old form
2056 "qualifier.set.name = <attributes>". (Both forms are still
2057 understood but the latter is deprecated.)
2058 * CQL terms with no explicit index specified are now interpreted as
2059 cql.serverChoice instead of srw.serverChoice (which of course
2060 behaves exactly the same.)
2062 --- 2.0.7 2003/12/16
2064 MARC conversion can now generate ISO2709 output in another
2065 character set. yaz-marcdump uses this facility if you invoke it
2068 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2069 functions from there can be used from C++.
2071 --- 2.0.6 2003/12/04
2073 Frontend server now transfers memory from decoded packages to stream
2076 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2077 references to show up.
2079 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2080 the ZOOM Abstract API. The older names for the same options are still
2081 also supported for the benefit of old applications.
2083 ZOOM-C supports "implementationId" and "implementationVersion" options
2084 to go along with "implementationName". These allow the user code to
2085 specify identification strings to be sent to servers.
2086 Add OID for the new ExtLite attribute set.
2088 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2089 as requested/supplid by Ere Maijala <ere@atp.fi>
2091 For generic frontend server, reverse the order of
2092 "toolkit-supplied / application-supplied" strings sent as implementationId,
2093 Name and Version. Also, remove the spaces around the slash. This brings
2094 the GFS in line with the behaviour of ZOOM-C on the client side.
2096 Add function ZOOM_scanset_display_term.
2098 yaz-client shows scan displayTerm if present.
2100 Utility yaz-iconv is now installed by default along with the man page
2103 Extend configure check for OpenSSL to use pkg-config where available (such
2106 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2107 server to specify uid/gid/mask for socket using the format
2108 unix:[user=uid,][group=gid,][umask=mask,]file=path
2109 If file= is omitted the existing format is assumed, e.g.
2111 in which case the mask is 0666 (rw for everybody).
2113 Major restructure of YAZ source. All source in libyaz is in src directory.
2114 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2115 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2117 Added man page for utility yaz-marcdump (used to be called marcdump).
2118 yaz-marcdump is installed by 'make install'.
2120 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2121 of incoming package failed.
2123 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2125 Change prototype of odr_perror: add const to message string.
2127 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2129 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2130 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2131 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2132 DNS lookup. There should not be any compatibility problems with this
2133 assuming that blocking=1 or 0 is used.
2135 Fix bad reference in UNIX comstack in function cs_addrstr.
2137 Fix for compilation on AIX.
2139 The generic front-end server (server/seshigh.c) now supports returning
2140 Init diagnostics to the client in User-information-field, in
2141 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2144 --- 2.0.4 2003/09/04
2146 Allow any CQL relation (not just all,any,exact,scr).
2148 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2149 that features the same UI.
2151 Implemented command update0 in YAZ client which is equivalent to
2152 update but uses old of Ext Update ASN.1.
2154 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2155 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2156 Previously no OID was used for this info.
2158 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2159 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2160 returns 'malformed search term' otherwise.
2162 SortResponse member resultCount now set to NULL in sort handler of
2165 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2168 Add three new utility functions for translating OIDs between various
2169 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2170 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2171 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2172 char *oid_to_dotstring(const int *oid, char *oidbuf);
2173 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2175 Reverted modifications for ES Update definition for z_IU0Update
2176 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2177 is back to YAZ 2.0.2.
2179 String value attributes for CCL parser.
2181 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2182 which their FirstSearch server returns in Init responses, sometimes
2183 carrying useful diagnostic information when Init fails. This has the
2184 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2185 "z39.50/oclcui.asn", where its definition is somewhat different from
2186 what OCLC document on their web-site, as required to interoperate with
2189 Support for anonymous authentication in yaz-client. Use the command
2192 * Fix the OID of the Index Data-local "admin" Extended Service from
2193 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2194 the 1000, which indicates a locally-defined OID, was a mistake.
2196 --- 2.0.3 2003/06/20
2198 Fix CCL directive @case handling so that it affects string match for
2199 both CCL keywords and qualifiers.
2201 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2202 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2203 Decoder has been updated with ASN.1 changes as listed in
2204 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2205 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2206 z_IUUpdate, remains unchanged.
2208 ZOOM_record_get may now return a record in a specific character set.
2209 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2210 "from" is the character set of record as returned by target. "to" is
2211 the character set to be returned. If omitted, "to" is UTF-8.
2213 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2215 New ODR utility, odr_getelement, which returns name of element for
2216 which encoding/decoding failed.
2218 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2219 in cases where a required element was omitted.
2221 Bug fix: some MARC8 sequences were not converted.
2223 New ZOOM option "step" which specifies number of records to be
2224 retrieved in one chunk. Used in conjunction with "start" and "count".
2226 SRW support for yaz-client. Use scheme http: to use it, e.g.
2229 yaz-client no longer does (un)intelligent character set conversions
2230 by default. Can be enabled with charset and marc_charset commands.
2232 xmalloc trace fix for 64-bit systems such as DEC alpha.
2234 Solaris 2.6 compile fix.
2236 New function, cql_strerror() translates SRW error codes, as returned
2237 by cql_transform_error(), into human-readable English strings. Used
2238 in yaz-client diagnostics when appropriate.
2240 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2241 converts it into a type-1 query which is sent to the server. This
2242 makes CQL available for use with all Z-servers, as opposed to the tiny
2243 minority that can handle CQL queries themselves.
2245 --- 2.0.2 2003/04/28
2247 New Debian package layout similar to the Redhat Package layout.
2249 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2250 and search result respectively.
2252 --- 2.0.1 2003/04/25
2254 Redhat package is now several packages: libyaz (runtime libraries),
2255 libyaz-devel (development and documentation, and yaz (utility programs).
2256 Package spec file by Morten Bogeskov.
2258 New member 'schema' in struct bend_fetch_rr which the name of requested
2259 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2260 handler MAY set this to reflect the schema of the returned record.
2262 New member 'display_term' in struct scan_entry. GFS now sets member entries
2263 and allocates scan entries to be filled by user scan handler. In previous
2264 version, entries member was allocated by the scan handler. That still works,
2265 but the GFS will ignore member display_term - assuming it was NOT set by
2266 the handler. The fact that the GFS now allocates the entries both allows
2267 for new members and makes a scan handler easier to write.
2269 Fix CQL lex buffer overflow.
2271 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2272 SRU default recordPacking is string.
2274 SRU protocol support for frontend server.
2276 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2278 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2280 Added scan for the ZOOM shell (zoomsh).
2284 * String Identifers for Schemas (Amendment 5).
2285 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2286 Old definition for schema
2287 Odr_oid *schema; /* OPT */
2292 Z_InternationalString *uri;
2293 #define Z_Schema_oid 1
2294 #define Z_Schema_uri 2
2297 * resultCount parameter to Sort Response (Amendment 1).
2298 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2300 Support for SRW 1.0 over HTTP. This is an optional feature and
2301 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2304 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2305 on the same port. SRW SearchRetrieveRequests are mapped
2306 to bend_init,bend_search,bend_fetch,bend_close.
2308 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2310 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2311 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2313 ZOOM connections are SRW based if schem http is used for hostname
2314 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2315 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2317 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2318 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2319 distance=n, order=true/false, relation=le, prox unit=word. If
2320 n is omitted, distance 1 is used.
2322 Fixed problem with C compiler include path in wrong order.
2324 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2325 on Solaris. Patch from Ko van der Sloot.
2327 New MARC decode API. All new functions operate on a yaz_marc_t
2328 handle. The most important new functions are: yaz_marc_create,
2329 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2330 decode and destroy respectively. Decoder can produce formats
2331 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2332 include/yaz/marcdisp.h.
2334 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2335 to UTF-8, UCS-32, wchar_t or Latin-1.
2337 * Prototypes for yaz_iconv_-functions moved to separate header
2338 include/yaz/yaz-iconv.h.
2340 Make a few private functions 'static' in unix.c. This prevents
2341 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2343 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2344 are set when Init Response is received.
2346 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2347 but returns diagnostic set as well.
2349 New function yaz_strerror which is a portable wrapper for
2350 strerror/strerror_r/GetLastMessage.
2352 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2353 is returned for MARC. If type is "oai", then OAI MARC is returned.
2355 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2358 --- 1.9.2 2002/11/26
2360 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2362 Fix bad race conditions on SIGTERM and terminate gracefully in
2365 Move retrieval (data1) module to Zebra since nobody seems to be
2368 Add GRS-1 render for ZOOM using same format as yaz-client.
2370 --- 1.9.1 2002/10/05
2372 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2374 Fix broken ESpec handling in data1 module.
2376 SGML reader parses comments and makes them part of the data1 tree.
2378 Added several type casts so that YAZ compiles as C++ code.
2380 ZOOM didn't handle PDU encoding failures properly.
2382 Added more Bib-1 diagnostics (approved extensions).
2384 GNU configure: better check for iconv.
2386 More portable use of accept, getpeername. Check for socklen_t. Use
2387 int/size_t if socklen_t is not defined.
2391 PQF parser rejects bad queries - including those with extra
2392 characters in them. PQF parser used to silently ignore that.
2393 Cleaner API for PQF added, which allows you to get detailed
2394 error information for bad queries (see yaz/pquery.h).
2396 Fixed bug in ZOOM_record_get for type "database".
2398 Implemented mini iconv library supporting conversions between
2399 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2401 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2403 --- 1.8.9 2002/08/20
2405 Fixed ZOOM C record cache so that preferredRecordSyntax and
2406 elementSetName is used to check for already fetched records.
2408 --- 1.8.8 2002/08/02
2410 Added three members in bend_initrequest structure to facilitate
2411 character set negotiation.
2413 Fixed a bug in frontend server that could cause indefinite
2414 loops under rare conditions.
2416 Revised character set utilities (charneg.h) so that encoding
2417 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2419 For PQF, directive @term <type> sets term type for Scan/Search.
2420 Here <type> is general, string, numeric, null. The term type
2421 is inherited - just like @attr.
2423 New call odr_set_charset that sets character set conversion for
2424 international-strings on a ODR stream. Prototype is:
2425 int odr_set_charset(ODR o, const char *to, const char *from);
2426 The InternationalString is still represented as C string in YAZ
2427 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2428 won't). On the protocol level, you can use any encoding.
2430 Support for UNIX sockets in ZOOM.
2432 Solaris recv sometimes returns errno == ENOENT. It is treated as
2433 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2435 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2436 both client and server. Code by Morten Bogeskov.
2438 --- 1.8.7 2002/05/22
2440 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2441 that they can be used directly from Visual Basic. You must recompile
2442 your windows APP if you're using ZOOM.
2444 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2445 Commands "lang" and "charset" sets language and character set respectively.
2446 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2447 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2449 Attributes from multiple CCL fields may be OR'ed rather than merged
2450 using directive "@field or". Fields are still merged by default -
2451 equivalent to "@field merge".
2453 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2456 Fixed bug in zget for parameter ExtendedServicesResponse.
2460 --- 1.8.6 2002/03/25
2462 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2464 Client displays USR.1:SearchResult-1 (hits per term).
2466 Additional Search Info for search in Generic Frontend Server.
2468 Fixed CCL parsing of "field=s".
2470 WIN32 installer - using the excellent NSIS software from nullsoft.
2472 Fixed CCL parsing of "field = - <number>".
2474 Added function yaz_marc_decode that decodes MARC for line mode
2475 display or XML (similar to that used by JZKit).
2477 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2478 Z39.50. But ISO/ILL was, however.
2480 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2481 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

2486 --- 1.8.5 2002/02/03
2488 New YAZ client features: Command completion and new commands:
2489 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2490 Code provided by Jacob Poulsen.
2492 New call oid_trav, that visits all registered OIDs via callback.
2494 Function ZOOM_record_get now returns const char pointer rather than
2495 void pointer. It saves a lot of type casts.
2497 For YAZ client, command "auth" now allows you to set authentication
2498 in IdPass style. It is enabled when three tokens are given - order
2499 is user, group and password.
2501 Fix memory leaks in MARC record handling for ZOOM.
2503 New option for YAZ client, -k <kilobytes> that sets
2504 maximum record size. Similar to -k option for generic frontend
2505 server and yaz-ztest.
2507 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2509 Prefix query parser reports "fail" when bad attribute set is given.
2511 Fix in MARC decoder. Proximity logging. Fix for attribute set
2512 in scan handler for server. Patches by Shigeru Ishida.
2514 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2517 Configure option --with-openssl=<dir> now works when a directory is
2518 specified. Patch provided by Morten Bogeskov.
2520 New option for YAZ client, -u <auth>, that sets authentication.
2522 ZOOM fix: error information was sometimes "missing", since error
2523 was cleared/reset too when it shouldn't.
2525 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2527 --- 1.8.4 2002/01/04
2529 Scan for ZOOM API. New object ZOOM_scanset. New functions
2530 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2531 ZOOM_scanset_destroy.
2533 New ZOOM function, ZOOM_connection_last_event, that returns type
2534 of last event (such as "receive data", "send data", "apdu received",
2537 New ZOOM option, schema, that specifies schema for retrieval.
2539 New CCL feature. Qualifiers can be aliases for one or more
2540 other qualifiers (if more than one is given, OR is used).
2542 ZOOM uses named result sets if target supports it.
2544 Two new YAZ client commands: . (dot, which sources a script of YAZ
2545 client commands), and ! (to execute shell command.). Implemented
2548 Working on Debian packages.
2550 --- 1.8.3 2001/11/19
2552 YAZ client enables named result sets only if target supports it.
2554 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2556 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2557 with key="host" to get same result.
2559 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2560 Function Z3950_resultset_record(s) returns references to records
2561 "owned" by resultset. To become owner use Z3950_record_clone.
2563 Function z_ext_record handles Extended Services. Thanks to
2566 --- 1.8.2 2001/11/12
2568 CCL Parser fix: ignore token comma when dealing with and-lists.
2570 Documentation updates for COMSTACK.
2572 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2573 Changed prototype Z3950_records. For some functions, int parameters
2574 were changed to size_t.
2576 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2579 New MARC decode/display function, marc_display_exl, which properly rejects
2580 non-ISO2709 records. YAZ client uses it.
2582 --- 1.8.1 2001/10/29
2584 Fix bug: local attribute set wasn't set correctly in PQF strings.
2588 * Old Z39.50 codecs no longer supported.
2590 Added ZOOM C binding. See http://zoom.z3950.org/
2592 Renamed states for COMSTACKs to avoid confusion with events.
2594 Implemented cs_look and proper cs_rcvconnect.
2596 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2598 Configure detects POSIX threads on OpenBSD.
2600 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2601 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2603 When error is returned from present handler, non-surrogate diagnostic
2604 is returned in present response (and fetch handler is no longer called).
2606 * Minor adjustments to pquery parser (PQF). Token characters may be
2607 escaped by using backslash (C-style).
2609 PQF parser allows string attribute values to be specified. For @attr,
2610 non-numeric characters after the equal-sign are treated as strings
2611 (e.g. @attr 9=title).
2613 CCL trunction character may be defined (@truncation in file)
2615 * function zget_ExtendedServicesRequest sets waitAction to
2616 waitIfPossible (was wait).
2618 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2621 CCL operator names may be set in field definition files (CCL_bibset).
2622 See ccl/bib1 for an example.
2624 Fixes in ASN.1 compiler for C++ compatibility.
2626 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2627 and "op_or" to avoid conflict with C++.
2629 Fixed problem with GNU readline detection on Redhat 7.0.
2631 Added step-size for Scan backend handler.
2633 Fixed bug that made the frontend server crash when no attribute
2634 set was specified for scan.
2636 Front-end server automatically switches to original working directory
2637 when installed as an NT service. Previously -w had to be specified to
2640 Added extended attributes for retrieval module (data1), so that data1
2641 records carry d1_readXML/SGML attributes. d1_read also supports
2642 null-data rules ( <tag/>)
2644 On UNIX when POSIX threads are available, a separate library libyazthread
2645 is created. Programmers should link with that library and the yaz library
2646 when using threads. The reason for the split was that some applications
2647 on Linux, such as Apache, doesn't work well when using shared objects that
2650 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2651 (or any frontend server) in SSL mode by specifying ssl: followed by
2652 address. Only tested on UNIX.
2654 Added feature for CCL module. Virtual structure s=al or s=ol generates
2655 and-list and or-list respectively instead of phrase search.
2659 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2660 log_mask_str. This was done to avoid name conflicts with other libraries
2661 (such as other PHP extensions).
2663 Added raw OID member for preferred record syntax (request_format_raw)
2664 and returned record syntax (output_format_raw) for backend fetch method.
2666 Config file yaz-config now accepts options so that it returns specific
2667 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2669 Shared library support for UNIX using GNU libtool.
2671 * Modified backend interface. Request/Response struct's replaced by
2672 one read/write C struct. For example bend_fetchrequest and
2673 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2674 Every handler - even search has to be registered in bend_init
2675 handler. This means that the YAZ library no longer refers to
2676 external functions and it makes it possible to make the whole
2677 thing a single DLL/SO.
2679 Added Segment handler for backend server.
2681 Added Zmbol/Zebra administrative functions to YAZ client.
2683 Threaded frontend server on UNIX (when POSIX Threads are available).
2684 Starting the server with option -T enables multi-threading.
2688 Added configure option --enable-comp/disable-comp to control use
2689 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2690 located in sub directory asn.
2692 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2693 in ${exec_prefix}/bin along with the other programs yaz-client and
2696 GNU automake used to maintain makefiles.
2698 Added several OID's.
2700 Changed retrieval module so that we can load records with no abstract
2701 syntax defined. Tagpaths in these records are fully composed of string
2704 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2708 On UNIX, the generated makefile now supports a proper 'make install'.
2709 The prefix can be set via GNU configure to set the install location
2710 (default is /usr/local).
2712 * YAZ programs client and ztest were renamed to yaz-client and
2713 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2714 locations, such as /usr/bin,/usr/local/bin,etc.
2716 * YAZ Header files were moved from include to include/yaz. YAZ Header
2717 files are referred to as include <yaz/log.h> rather than <log.h>.
2718 The YAZ include path (-I ..) is therefore the same as before. Programmers
2719 should update their #include statements or use -Ipath/include/yaz
2720 instead. The main motivation for doing this change is that YAZ header files
2721 can be installed in "standard" locations /usr/include,/usr/local/include
2722 without introducing conflicts, since ALL YAZ header files are stored
2723 in subdirectory yaz (under /usr/include for example).
2725 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2726 rather than project/workspace files. We switched because project files
2727 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2730 Changed name of logging function, logf, to yaz_log, to prevent name
2731 clash with some math-log functions. The YAZ header log.h defines logf
2732 to yaz_log (#define) so there should be no incompatibilities by this
2735 Added bend_start/bend_stop handlers for server. These handler are
2736 called on start/stop of server. For windows they are called whenever
2737 a service is started/stopped.
2739 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2740 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2741 in util/yc.tcl. The auto-generated C code structures are, in a few
2742 cases, incompatible with the old decoders. There are differences in the
2743 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2744 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2745 The preprocessor variable ASN_COMPILED is defined when the compiled
2746 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2747 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2748 wish to use the old encoders/decoders you can specify --disable-yc
2751 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2752 version so that it supports both new - and old version of DB Update
2754 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2755 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2756 change. The name parameter can be set to 0 in which no name is specified
2757 for the construction. The macros odr_implicit and odr_explicit sets name
2758 parameter to zero for the construction involved. New macros
2759 odr_implicit_tag and odr_explicit_tag are similar to the others,
2760 except that a name parameter is added. For programmers' that don't use
2761 ODR they probably only need to change the call to z_APDU and z_External.
2763 Added access control facility by interfacing the TCP wrapper library.
2764 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2765 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2766 name of the daemon and enables the access control as specified in
2767 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2769 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2770 den Dool <H.M.vdnDool@kub.nl>.
2772 Added reference ID parameter to most functions in server API - refer
2773 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2775 Changed name of ccl library to libccl.a (was ccl.a).
2777 Fixed bug in decoder for Explain (Category TargetInfo).
2779 Added support for GNU readline in client. Thanks to Jacob Poulsen
2780 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2782 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2783 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2784 IMPLEMENTATION! This change was made to the development version before
2785 the ZIG decided to retract the amendment. If any users MUST be
2786 compatible with the original Update definition, PLEASE CONTACT US, and
2787 we will include a separate definition corresponding to the old Update
2788 ES. Note that because of the change to the ASN.1 of the
2789 TaskPackageRecordStructure we cannot define a single structure that
2790 will support both versions.
2792 * Added const modifier to buffer parameter for some ODR/BER encoding
2793 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2794 completeWAIS, odr_dumpBER.
2796 Fixed bug in client.c which caused a crash when a scanResponse didn't
2797 contain positionOfTerm.
2799 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2800 * will cause an error in a client if a non-YAZ target sends both a
2801 * list of Scan entries and non-surrogate diagnostics.
2803 Retrieval module enhancements. Tag sets may be typed in the reference
2804 to it. From the .abs-file the "tagset" directive takes a third optional
2805 integer type for the tag set referenced. From a .tag-file the "include"
2806 directive takes a third optional type as well. The old "type" directive
2807 in the tag set itself is still recognized but acts as the default type
2810 Backend interface change. Individual Scan terms returned from bend_scan
2811 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2812 in include/backend.h.
2814 Retrieval module enhancements. Multiple tag sets and attribute sets may
2815 be specified in abstract syntax specs. Revised the error/warning for
2816 logging messages reported by the retrieval module when reading the
2819 Object Identifier system (oid_..) changed. The API is backwards
2820 compatible but the oid-routines now allocates new OID's when needed.
2821 Raw OID's may be specified in oid_getvalbyname.
2823 YAZ now uses GNU configure to generate Makefile(s).
2825 * Minor changes in some of the member names of DeleteResultSetRequest and
2826 DeleteResultSetResponse. See include/proto.h.
2828 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2829 and added member 'languages' in TargetInfo (which was missing).
2831 Changed the way attribute sets are handled in the retrieval
2832 module. These are now cached, just like the abstract syntaxes
2835 Changed YAZ so that it links with compiled ASN.1.
2837 Added Explain-schema definitions and mapping routines. The following
2838 Explain categories have been implemented: AttributeDetails,
2839 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2841 Fixed minor bug in Windows version of Server Library.
2843 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2845 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2847 Added EXTERNAL: UNIverse Resource Report (non-standard).
2849 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2850 ENUMERATED and SET OF.
2852 * Added 'const' to some of the char pointer arguments for the
2853 functions, data1_read_node, data1_getelementbytagname,
2854 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2857 Fixed bug in data1_insert_taggeddata - the last_child member of
2858 parent wasn't initialised.
2860 * Changed data1_read_record and data1_read_node so that the supplied
2861 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2862 doesn't refer to any parts of the "SGML"-buffer.
2864 Fixed bug in server library (Windows version of statserv_remove).
2866 * Changed code so that it compiles as C++. The type definition
2867 of Odr_fun which is a member of Odr_arm was changed. The result is,
2868 that an explicit typecast is needed for the fun pointer when
2869 using Odr_arm - as in:
2870 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2872 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2874 Implemented the new structured date and time definition as approved
2875 by the ZIG. Added schemaId element to the specificTag in Espec-1
2876 (also approved at the last ZIG). Thanks to RVDM.
2878 Added some Object identifiers (RVDM).
2880 Changed the Update Extended Service (RVDM).
2882 Added command "refid" to client which specifies referenceId for
2883 the following requests.
2885 Implemented extended service handling for server. See ztest.c
2886 for an example as well as backend.h. New handlers are registerd
2887 in the Init handler.
2889 * Changed interface for sort in server.
2891 Added new members to statserv_options_block. It allows a server
2892 to read options from another source than just the command line. Thanks
2893 to Charles Woodfield.
2895 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2896 renamed to zboolean. Some C++ compilers complained about the name.
2898 Minor changes to gils.abs. Added index 's' (sort) on title
2899 and date/time-last-modified.
2901 --- 1.4pl2 1998/1/30
2903 Fixed bug in server library regarding inetd mode (-i). This bug
2904 was introduced by release 1.4.
2906 --- 1.4pl1 1998/1/29
2908 Added sort facility in client and backend server interface.
2910 Fixed problem with dependencies in Makefile(s).
2912 Fixed bugs for encoders/decoders of extended services and
2915 Implemented sub-tree feature for schemas. Sub-trees are
2916 referenced in *.abs-files. See explain.abs for an example
2917 of the use of this feature.
2919 Modified bib1.att; local attributes for ANY didn't include
2920 ANY itself (only affects use of the retrieval module).
2922 Fixed bug in plain SGML reader in function data1_read_node:
2923 tags with prefix "var" was incorrectly interpreted as variants.
2925 Added feature "sub-schemas" to enable references to - and definitions
2926 of - group of elements.
2928 * Removed member parent from type data1_element (in data1.h).
2930 Implemented function odr_nullval() that returns the value of
2933 * Removed member num_children from data1_node (in data1.h).
2935 Made NT service interface part of the server library. The
2936 function statserv_main uses the NT service when required and
2937 calls the statserv_start / statserv_close routines.
2939 Routine zget_SearchRequest and zget_PresentRequest fills
2940 resultSetName/Id member with "default" instead of "Default".
2942 Fixed memory leak in server. Request queue member wasn't freed.
2944 Fixed nmem_exit so that memory is freed.
2948 Revised the CCL parser utility to be thread safe.
2950 Added function, oid_ent_to_oid, to replace the function
2951 oid_getoidbyent, which is not thread safe.
2953 * Added nmem_init and nmem_exit to initialize and release
2954 NMEM resources. Function nmem_init should be called once in the
2955 initial thread before NMEM/ODR is used. statserv.c and client.c
2956 have been changed accordingly. The change was necessary to make
2957 NMEM thread safe. The NMEM memory pool is shared amongst threads
2958 in a process. Unix-based applications will still work fine without
2961 Added NT Services interface for the the Z39.50 (statserv) Server.
2962 Refer to the ztest.c source on the usage.
2964 Windows 95/NT port using MSVC5.0. Project files are included in the
2967 * Defined new 'global' handle for the retrieval (data1) system. The
2968 new handled, data1_handle, describes the state of the data1 system.
2969 This handle is passed as first argument to virtually all
2970 data1 related routines. The functions data1_create and data1_destroy
2971 creates and destroys a data1 handle respectively.
2973 Added ODR encode stream member to all backend request structures
2974 init, search, scan etc. This stream should be used to allocate all
2975 memory used for the response when thread safe operation is needed.
2977 Changed the comstack utility, cs_addstr, to be thread safe. The
2978 returned hostname string returned by the function is now part the
2981 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2982 function. The cs_straddr takes a COMSTACK handle as argument, so this
2983 function must be used after cs_create and before bind/connect.
2984 This function is thread safe.
2986 Moved test server to 'ztest' directory - generic server code still
2987 in 'server' directory.
2989 Made prefix query (pquery.c) utility thread safe.
2991 Added new function modifier YAZ_EXPORT to 'export' public DLL
2992 functions when using windows (see include/yconfig.h).
2994 Added definitions to the OID database (util/oid.c) (RVDM).
2996 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2998 Added call to ccl_rpn_delete in client program.
3000 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3001 release of RPN structure.
3003 Added support for C++, headers uses extern "C" for public definitions.
3004 With input from RVDM.
3006 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3007 Thanks to Ronald van der Meer (RVDM).
3009 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3011 Added support for private extensions to the OID database
3012 (oid_setprivateoids()). Thanks to RVDM.
3014 Added optional, physical ANY (key replication)
3016 Fixed null-reference problem in GRS-1 output filter.
3018 Proximity operator added to Prefix Query Format (PQF).
3020 In test client command "base" accepts multiple databases.
3022 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3026 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3028 Smallish bug-fixes in the new encoders/decoders (explain).
3030 Bug fixed in DeleteRequest.
3032 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3034 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3036 Added SOIF syntax (using private OID for now) to retrieval module and client.
3038 Added Update extended service.
3040 Added SearchResult-1 additional info structure.
3042 Added optional CCL (ISO8777) interpreter as separate module. Available
3045 --- 1.2 1996/6/10 (1st anniversary release)
3047 Added Summary record syntax. Lightly tested.
3049 Added OPAC record syntax. Untested.
3051 Added ResourceReport service encoders/decoders. Untested.
3053 Fixed bug in z_Unit - wrong tagging on unitSystem.
3055 Fixed bug in the DiagRecs decoder.
3057 Added options for max PDU size and session timeout to frontend-server.
3059 Added documentation of query-language parsers and other supporting utilities.
3061 [frontend-server] Added Attribute set to the bend_scanrequest API.
3063 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3064 surrogate diagnostics were generated.
3066 [retrieval] Allow multiple local values for attribute.
3068 [retrieval] Allow multiple attributes per element in .abs files. index type.
3070 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3072 --- 1.1pl2 1996/4/10
3074 Minor changes, mostly specific to Zebra's requirements (retrieval)
3078 Repaired bug in frontend server when running multiple listening
3079 endpoints in dynamic mode.
3081 z_External() now won't break if a known, ASN.1 value comes encapsulated
3082 in an octet-string. The value will pass through unmodified in an Odr_oct.
3084 Added a bit of code to the demo client to decode & display
3085 ASN.1-structured records represented in the octet-aligned branch of
3086 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3088 Added z_ext_getentbyref() to the ASN module. Doc updated.
3090 * Completed the SCAN definition in the ASN module. This may break SCAN
3091 code based on older YAZ-versions at compile-time. The fix is easy -
3094 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3095 under the SCAN definition. Remember to initialize this, server-people.
3097 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3098 that this does not extend to ODR and ASN.
3100 Comstack allows insertion of established socket (primarily for
3101 inetd-operation of servers). Doc updated.
3103 Front-end server can now start from the inetd in TCP mode. Doc
3106 --- 1.0pl4 1996/1/24
3110 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3111 the rank and record number.
3113 Adjustments to the frontend server.
3115 Fixed diagnostic BER dumper. It ignored the file argument.
3119 Various changes to retrieval module.
3121 Changed the union discriminators of the protocol files from enums to
3122 ints paired with #defines.
3124 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3127 *Changed operator in the RPN structure to 'roperator', again to avoid a
3130 Fixed problems in Explain decoders/encoders.
3132 --- 1.0pl2 1995/12/6
3134 Memory bug in log module fixed.
3136 --- 1.0pl1 1995/12/5
3138 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3140 Bug in Explain DatabaseInfo module fixed.
3142 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3146 The shift to v1.0 signals that we now consider the *core* functionality
3147 of YAZ reasonably stable (the core being more or less equivalent to
3148 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3149 tested (Explain not at all - though that will happen soonish).
3151 Minor changes to code to support Windows port.
3153 Various minor changes after we're getting to use GRS-1 & co. more.
3155 Added Espec-1 format.
3157 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3158 of the protocol and it cannot be selected when encoding (maps into 'string'
3159 when decoding). Needed to talk to some servers.
3161 Demo client can request simple element set names.
3163 Added Diagnostic Format encoders/decoders.
3165 Added simple Close handling to frontend server (no hooks for resource
3166 reporting yet), and demonstration client.
3168 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3170 --- 1.0b3 1995/08/24
3172 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3173 handled incorrectly when records were requested in the searchResponse. This
3174 will only affect you if you use the frontend-server.
3176 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3177 Test-client will ask for and print GRS1. Ztest will return dummy records
3180 Added Explain encoders/decoders to the service-level API. Untested.
3182 Added Extended Services: Item Order encoders and decoders to the Service-
3183 level API. Untested. We could use a recent copy of the pertinent bits
3184 of the ILL protocol to add those bits.
3186 Added diagnostic format 1 encoders/decoders to the service-level API.
3189 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3190 odr_cons.c, which causes a more correct output.
3192 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3193 was always set to 0 when no records were requested in the searchRequest.
3195 * Added better external-handling. This shouldn't harm old code that
3196 *encodes* externals. It can break code that looks for a
3197 'single-ASN1-type' representation, since those types that are known
3198 are now decoded immediately. Look at the SUTRS sample code in
3199 seshigh.c and client.c. Documentation updated.
3201 Handling of structured records in bend_fetchresponse. Length -1 marks
3202 structured record, type is deduced from format field.
3204 --- 1.0b2 1995/06/27
3205 Fairly quick maintenance release to add SUTRS support.
3207 Fixed handling of SUTRS records in the demonstration client.
3209 * Added format field to the bend_fetchrequest and bend_fetchresponce
3210 structures of the backend API (frontend server). When the record is
3211 returned, the value of the format field is mapped to an OID. The
3212 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3213 of the record. The special value VAL_NONE in the bend_request means
3214 that no specific format was requested by the client. Documentation
3215 updated accordingly. Test server (ztest) will return a fixed dummy
3216 SUTRS record if your client requests SUTRS.
3218 Documentation updated accordingly.
3220 You can now set external libraries and RANLIB support in the top-level
3224 First public release.
