3 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
4 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
8 YAZ daemon utility relays SIGUSR1 to child process.
10 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
11 would result in en empty database list - which in turn would result in
12 encoding failure for search.
14 Fix reading beyond string in yaz_sort_spec.
18 Add two new SRU diagnostics:
19 236: Access to specified database denied
20 1015: Init/AC: Maximum number of simultaneous sessions for Userid
22 Document the very useful ZOOM-C option "apdulog".
24 CQL to RPN: term may be passed through verbatim. This is enabled with
25 truncation.cql . The assumption being that the term is already CQL.
29 record_conv: leader spec may be given for marc element.
30 The leader spec is given as attribute leaderspec for element marc.
31 For example to convert a MARC21 record from MARC-8 to UTF-8:
32 <marc inputformat="marc" outputformat="marc"
33 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
35 record_conv: allow user-XSLT params. For example:
36 <xslt stylesheet="MARC21slim2DC.xsl">
37 <param name="myparameter" value="myvalue"/>
38 <param name="otherparameter" value="othervalue"/>
41 record_conv: fix error handling for missing marc charsets.
43 CQL: fix extra terms in wrong order.
47 record_conv: modify new API for conversion types. The conversion types
48 may be passed in new functions yaz_record_conv_configure_t and
49 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
51 Avoid mixed statement/variable declare; fixes compilation with Visual
56 Add non-standard SRU diagnostic: 235: "Database does not exist".
57 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
58 Update SRU to Bib-1 diagnostic maps accordingly.
60 CCL: add two new diagnostics for unsupported masking. The new
61 diagnostics are: "Embedded truncation not supported" and
62 "Single charcacter mask not supported".
66 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
70 Build YAZ for Ubuntu Oneiric.
72 CCL: allow parantheses for proximity operands. For example CCL query
73 (a) % (b) is now allowed.
75 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
76 marked dead, rather then being destroyed. If not, the session memory is
77 being free'd before the search/scan handler is finished. Also destroy
78 'request' memory in request_release rather than in various places,
79 which resulted in leaks from time to time.
83 cql_sortby_to_sortkeys: honor sort prefix.
85 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
86 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
87 The rpn2cql family of functions now always returns quoted CQL terms.
89 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
93 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
94 sequence is treated as one. For example, &&a=b&&&c& is identical to
99 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
100 APDUs for a connection to a WRBUF.
102 --- 4.2.21 2011/11/23
104 Fix cql_sortby_to_sortkeys. Completely broken before.
106 Make CCL's @truncation work again.
108 --- 4.2.20 2011/11/09
110 New ZOOM connection setting: tproxy. It's like proxy, but does not
111 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
112 to set resolved address + port for a connection outside ZOOM itself.
114 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
116 --- 4.2.19 2011/11/07
118 Fix uninitialized variable in Solr spell support (could cause SEGV
119 for SRU response decoding).
121 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
122 back-end's addinfo through into the ZOOM response addinfo.
124 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
125 they are separated by a colon and a space rather than simply
128 --- 4.2.18 2011/10/28
130 Add support for Solr spell-checking/suggestions through ZOOM.
131 If a Solr target has been configured correctly for spelling-checking
132 and suggestions, these will now be returned on the ResultSet option
133 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
135 --- 4.2.17 2011/09/28
137 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
138 with a flag whether to substitute escape sequences or not.
140 --- 4.2.16 2011/09/22
142 Fix nmem_strsplit_escape to substitute escape char properly.
144 New option for zoomsh -e , which makes it abort on first error and
145 return process exit code to indicate success/failure.
147 YAZ options utility supports special option -- which makes all it treat
148 all following arguments as non-options.
150 --- 4.2.15 2011/09/16
152 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
153 searched if absolute filename is given.
155 Fix conv_xslt() error-reporting when stylesheet is not found.
156 (The value of fullpath is meaningless in this situation.)
158 --- 4.2.14 2011/09/07
160 Fix problem in CQL sort node creation: un-initialized memory.
162 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
163 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
164 CQL sortby depending on whether Type-1 or CQL is actually sent to the
167 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
168 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
170 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
171 will make it possible to use both single-character mask (#) and wildcard (?)
172 in CCL . Throw diagnostic for left truncation because that is not supported
175 --- 4.2.13 2011/09/01
177 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
178 cases using escapes (\-sequences) and masking.
180 PQF parse fix: A trailing backslash followed by end-of-string (\0)
181 would result in a read one byte beyond string.
183 rpn2ccl may use Z39.50 masking for terms (t=z).
185 ICU check fix. Don't include library -lCrun on Solaris, unless present.
187 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
188 not --cppflags (which seeems like an error in icu-config).
190 --- 4.2.12 2011/08/27 RPM package only
192 cql2ccl: fix conversion of terms: operator characters were not
195 --- 4.2.11 2011/08/25 RPM package only
197 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
198 CCL parser will map both # and ? to their regular expression
199 quivalents (. and .*).
201 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
202 of reserved CQL characters.
204 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
205 is, so that they are passed through.
207 --- 4.2.10 2011/08/24
209 ZOOM SRU mode: more aggressive re-connect.
211 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
212 made available as a utility function, declared in <yaz/logrpn.h>
214 rpn2cql_structure() supports proximity nodes (except that the Type-1
215 proximity node's "exclusion" binary is ignored, as there is no way to
216 express that in CQL). Fixes bug #4564.
220 Fix SEGV that could occur if set command of zoomsh was given without
221 value (2nd argument).
223 Fix SEGV that could occur if unsupported transport was given for
224 COMSTACK - say https (when SSL was unavailable).
226 Build yaz-url on Windows too.
230 New utility to get web content. Header is url.h. A command line tool
231 yaz-url is part of the distribution and packages.
233 Fixes for SSL COMSTACK (when gnutls is in use).
235 New functions yaz_base64{encode,decode}. Header is base64.h.
239 ZOOM C includes HTTP response buffer as additional info if it fails
240 to decode the SRU response.
242 Make wrbuf_json_puts available.
246 zoom: throw diagnostic for invalid value for option "sru". Before a
247 bad SRU request was sent.
249 Adding new utility wrbuf_vp_puts.
251 Add cclxmlconfig.obj to win/makefile. It was missing completely.
255 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
256 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
257 redirect was used at the same time.
259 MARC line mode decoding: be less picky about length given - first
260 5 digits of header that is.
262 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
264 Changes to decoding of SRU records: a record with recordPacking=xml is
265 modified with a new root element <yaz_record> if the recordData contains
266 multiple children elements. This is to make the record XML parseable
269 RPN to SOLR conversion: encode special characters.
271 Generic Frontend Server: fix uinitialized member, stepSize.
275 Fix a bug in SRU decoding of records.. The database records stored
276 had un-initialized memory, but it would only be seen with yaz_record_render
277 and type_spec="ext" .
279 Fix a bug in ccl_qual_dup introduced in 4.2.3.
283 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
287 Add new utilities to convert from CQL to CCL . These utilities have
288 prefix cql_to_ccl defined in cql.h.
290 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
291 lead to memory heap corruptions when ICU utilities were in use.
295 Make compilation work without Libxml2.
297 yaz-client: remove redundant blanks in display of searchResult-1 term
302 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
303 resulting CQL node (tree) in a new node CQL_NODE_SORT.
305 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
306 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
307 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
308 Note that the CQL sortby spec is only converted when the GFS is already
309 converting from CQL to RPN (cql2rpn element).
311 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
312 specify whether to collapse delimitors or not. The existing nmem_strsplit
313 do collapse (collapse parameter = 1).
315 Windows installer: For NSIS, set InstallDir depending on x86/x64.
317 Rename internal func yaz_use_attribute_create. While non-static, this
318 function is not declared in a public header.
322 Add -lCrun when linking with ICU on Solaris.
324 More quicks character set conversions for OPAC records.
328 fix problem with record_render: records were converted (character set
329 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
333 SRU: add methods for handling DADS SRU-proxy facets.
335 Separate OPAC record character set for ZOOM_record. yaz_record_render
336 allows a character set given as charset=from/opacfrom,to where 'from' is
337 the character set of a bibliographic record, 'opacfrom' is character set
338 of OPAC record and 'to' is the target character set.
342 yaz-client: show may XML format records. Command show followed by 'format'
343 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
346 src/stemmer.c: Avoid using unnamed union. It is not supported by some
349 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
352 Update yaz.spec to operate on both SLES11 / Centos 5.5.
354 RPM: Release includes 'indexdata' name. Use indexdata in release name so
355 this package can be distinguished from other vendors.
357 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
358 as determined by configure
360 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
362 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
363 returns no error and no record, the present request is considered
364 partial (only a subset of the records could be returned by backend), and
365 so it is appropriate to set Present Status to partial-4.
369 Move yaz-config man pages to section 1.
371 More documentation about SOLR.
373 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
374 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
375 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
376 peers on some Linux systems. However, in general that does not work
377 so YAZ can not rely on that to work. Debian changed behavior in this
378 respect from Debian lenny to Debian squeeze (still testing as of Oct
380 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
382 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
386 Fix yaz-config output: echo_source not set correctly by configure.
390 SOLR WebService support for yaz-client and ZOOM.
392 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
394 --- 4.0.12 2010/08/17
396 Z39.50 facet support. Facet specifications are passed for search in
397 other-information with ASN.1 as defined in facet.asn and OID
398 .10.1000.81.5 . Facets are expressed as an Attribute list as known
399 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
400 3 is limit (number of entries to get in response). yaz-ztest returns
401 dummy facets if a client asks for them.
403 --- 4.0.11 2010/07/09
405 CCL fixes: bug 2895 and bug 3539.
407 GR1-display: add comma in display - was removed by mistake in
410 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
412 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
414 --- 4.0.10 2010/06/18
416 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
417 result set from a connection. The result set will be on its own
418 thereafter; no operations on it will perform retrievals from a target.
419 Only cached copies are returned.
421 ZOOM C:fix case for HTTP servers responding with Connection:close.
422 Ensure that if there is a current task it is resumed (like fetching
423 more records in a result set) . Bug #3484.
425 PQF parser: use odr_atoi for Odr_int (not atoi)
427 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
428 values that contain any non-digits are treated as string attributes
429 (previously decoding only checked for leading character ([0-9]). PQF
430 encoding: attribute string values are not surrounded by double-quotes.
434 New utility for managing threads - thread_create.h.
436 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
437 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
438 but YAZ' implementation do.
440 Fixes for yaz_cond-functions on Windows 7.
442 DLL export more symbols.
444 zoomsh: show record do NOT render opac.
446 Remove *.la files from Debian and RPM packages.
450 Debian package libyaz-dev depends on libgnutls-dev again (was
451 removed in YAZ 4.0.6, but due to Libtool it is still needed
452 even though yaz-config do not list libgnutls libs).
454 ZOOM: Use only one WRBUF for returning string results for
455 ZOOM_resultset. Reduces memory usage for ZOOM in general.
457 ZOOM: ZOOM_connection do not use a shared pointer to
458 ZOOM_resultset after ZOOM_resultset is destructed by
459 user. Reverts to YAZ 4.0.4 behavior.
463 record-conv: fix problem with at least one XSL conversion -
464 due to probably incorrect usage of XML XSL documents.
468 Fix yaz-config for static mode and the use of SSL (gnutls).
472 Forward decl timeval struct in mutex.h and gettimeofday.h.
474 yaz-config: fix 'static' mode linking.
478 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
479 are wrappers for pthreads or Windows. For Windows these are put in
480 a separate DLL: yaz_cond4.
482 libyaz.la (whole source) is compiled with thread. If thread support
483 is enabled enabled, all source of YAZ is compiled with treading support.
484 This allows core utilities such as yaz_log to use thread facilities.
485 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
486 thread utilities. This commit moves mutex utilities (mutex.c) from
487 libyaz_server.la to libyaz.la.
489 yaz-json-parse displays leading text until error.
493 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
494 patch from Giannis Kosmas.
496 SRU: no longer URL encode SRU database. The URL for an SRU server is
497 a URL and such is alreeady encoded - at least when given with leading
498 http:// or https://. This reverts behavior to YAZ 3.0.50.
500 Support for new MARC XML notation TurboMARC which like MARCXML is a
501 complete representation of MARC/ISO2709.. This one, however, is more
502 compact and allows for faster processing with XSLT. TurboMARC can be
503 used in the marcdisp.h API, from the yaz-marcdump utility and from
506 yaz-ztest can be configured - via the database - to perform certain
507 delays when it performs operations search, present and single record
508 fetch. This allows testers to make yaz-ztest act as a real or even slow
509 Z39.50 server. Refer to the yaz-ztest man pages for details.
513 wrbuf_destroy allows NULL WRBUF passed to it.
515 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
517 Add ZOOM_connection_close.
519 No fixed size buffers for ZOOM shell - bug #3257.
521 tstodr: make it work on s390 platform.
523 New icu iterator-functions. The new icu_iter-functions makes it possible
524 to use ICU chains from many threads.
526 yaz-client: better syntax check for show command.
530 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
533 New simple local-file XML include facility which allows file glob-patterns.
534 Refer to yaz/xml_include.h.
536 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
539 ZOOM_record_get supports new parameter "format" which makes it format XML
542 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
543 JSONText in ECMA-262) is JSONValue, not JSONObject.
547 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
548 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
550 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
551 POSIX/Unix builds .so with major version 4.
553 Remove old LOG_-defines from log.h. They have been obsolete and
554 undefined by default for the last 5 years.
556 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
558 GFS: Remove socket (int *fd) from search_rr handler. The socket
559 descriptor ptr is a facility that allowed a search handler to supply
560 a socket which would serve as a callback - when search was complete.
561 This facility has now been in use for years.
563 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
564 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
565 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
566 returns 'const char *' rather than 'char *. The returned string is
567 read-only and should not be modified by applications. COMSTACK cs_close is
568 now a void function - it no longer returns int. No applications check for
569 the value and the implementations has always returned 0.
571 ZOOM: use size_t for scan hit counts and str size. Functions
572 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
573 occ (hit count) and len (string length) are now of type size_t pointer
574 rather than int pointer. This is to be able to represent large hit counts
575 and to also just to use the proper type for string length (strlen result).
577 New JSON parser. Refer to include/yaz/json.h .
579 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
580 Used to be int in some cases. Many wrbuf_-functions used to return an int
581 indicating some length.. These return values were never used. And so they
584 ODR: odr_malloc, odr_total now takes size_t for size.
586 clone_z_type: fix leak; occurred for encoding failures.
588 --- 3.0.52 2009/12/03
590 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
591 bug was introduced in 3.0.51.
593 --- 3.0.51 2009/12/02
595 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
597 tcpip comstack: fix leak for getaddrinfo.
599 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
600 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
601 Decoding of SRU "path" database is performed by private function
602 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
603 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
605 yaz-client: honor base command for SRU. Change when database setting
606 is applied for SRU and ensure it is kept when a connection is reset.
607 Change also the way errors are displayed or SRU (decoding of packages).
609 --- 3.0.50 2009/11/02
611 Add support for extra request / response data for SRU codecs and GFS.
612 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
613 for extra data response buffer and length. For the GFS, both request
614 and response data (XML) is carried in extra_args and extra_response_data
615 for the search handler. Patch by Ko van der Sloot.
617 ZOOM: For queries that cannot be converted to the specified rpnCharset,
618 ZOOM now returns a diagnostic on the client-side ('invalid query' /
619 10010). This fixes bug #2113.
621 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
622 cmdfile included a 'quit' command that would result in a memory violation.
624 --- 3.0.49 2009/10/01
626 Make a number of functions defined in xmlquery.c static. These have
627 never been declared in a public header file (yaz/xmlquery.h) and was
628 made public by mistake.
630 Improve speed of character conversions (iconv utilities). This makes
631 conversions from MARC-8 faster.
633 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
634 unless type desired is "raw". This will prevent type "xml" from
635 returning ISO2709 .. Which obviously can not be XML parsed.
637 Fix memory leak in ZOOM that would occur if option apdulog was used
638 on a re-used connection.
640 Frontend server logs HTTP requests.
642 Frontend server now sends Z39.50 close when it times out (sesssion has
643 been idle for too long). Versions 2.0.30 and earlier also sent close.
644 But due to a mistake this was disabled in all versions after that, i.e.
645 the server would just close the socket immediately.
647 yaz-client emits a better message when receiving an unrecognised
648 userInformationField.
650 Skip zero-length subfields when decoding ISO2709. This rare case happens
651 if a record has two FS characters in a sequence. Without this patch
652 there would be a reference beyond char array in using_code_len fragments
655 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
657 --- 3.0.48 2009/08/28
659 The show command offered by the zoomsh command now takes a 3d optional
660 parameter type which is what is passed to ZOOM_record. If the type
661 argument is omitted, "render" is used.
663 RPN to CQL conv may use USE string attributes (bug #2978).
665 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
667 --- 3.0.47 2009/07/08
669 Function yaz_xml2query allows a diagnostic element in the PQF XML
670 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
671 code and additional info respectively.
673 The BER BOOLEAN is now the integral type Odr_bool which still happens
674 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
675 typedef'd to Odr_int. This is still an integral 'int', but it may be
676 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
677 ASN-1 compiler as well as programs has been updated to use the new types.
679 --- 3.0.46 2009/06/08
681 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
682 only the bibliographic record was rendered. For type=opac, an OPAC
683 record is only returned if it is present.
685 iconv: small fix for encoding of advancegreek.
687 yaz-client: avoid double display of SRU/SRW records (bug #2798).
689 yaz-client: option auto_reconnect=on really reconnects.
691 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
693 server: avoid null ptr ref for for yaz_poll errors.
695 build: fix RPM build for RHEL 5.3.
697 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
699 --- 3.0.45 2009/03/31
701 Fixed bug #2709: TCP connect returns Invalid argument.
703 Fixed compilation for mingw.
705 Honor charset for raw records (ZOOM_record_get).
707 Fixed use of errno for threaded mode that was seen on Solaris 10.
709 Fixed argument passing with blanks in value for Windows Service.
711 Disable YAZ' own log rotate by default (no 1 GB limit).
712 The variable l_max_size which specifies the log file limit is set to 0
713 (DISABLED): This is due to the fact that YAZ is most often deployed using
714 logrotate. Also YAZ can not perform log rotate because of unsufficient
715 permissions (setuid).
717 --- 3.0.44 2009/02/17
719 List supported encodings in man page for yaz-iconv.
721 Fixed missing SSL libs for --libs output
723 Re-established OID record syntax application-xml. Nobody should use it
724 but we don't want to change soname because of this symbol being absent.
726 --- 3.0.42 2009/02/02
728 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
730 Added member named_result_sets for init handler struct for the GFS. This
731 allows a server to disable named result sets.
733 Removed OID record syntax application-xml.
735 Added support for rule-based transliterator for ICU wrapper of YAZ.
737 Fixed bug #1902: yaz-icu XML output.
739 Make YAZ checks Emacs friendly.
741 BITSTRING value shows value. Bug #2346.
743 ISO2709 decoding: skip control characters from indicator data.
745 Omit sort key by default in yaz-icu's output.
747 Allow combined single char options (again) for YAZ' options function.
749 Utility yaz-marcdump got option to display YAZ version (-V).
751 Allow YAZ to use ICU 3.4.
753 Added new ICU test case which illustrates removal of diacritics.
755 --- 3.0.41 2008/12/29
757 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
759 --- 3.0.40 2008/12/29
761 For configure, using option --without-xml2 also disables Libxslt/Libexslt
764 Fixed bug #2352: yaz-marcdump crashes for certain record.
766 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
768 Added support for Danmarc2 to UTF-8 conversion.
770 Added support for ISO5426 to UTF-8 conversion.
772 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
773 implementation version.
775 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
777 --- 3.0.38 2008/11/10
779 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
780 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
782 ZOOM C now interprets databaseName option for ZOOM connection as path
785 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
787 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
789 Dummy Libxml2 types no longer defined in headers of YAZ'.
791 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
794 --- 3.0.36 2008/09/26
796 Various ODR chapter fixes.
798 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
800 Added missing source for Windows compilation, mutex.c.
802 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
804 For SRU connections in ZOOM all records up to "count" are now fetched.
806 Fixed crash in generic frontend server (and yaz-ztest) which occurred
807 in Windows due to bad error handling for Libxml2.
809 Added facility for sending arbitrary records (ASN.1 any) using
810 ZOOM C's Extended service update. Patch by Sam Reynolds.
812 New options for ZOOM C's connection, logapdu which makes ZOOM log
815 --- 3.0.34 2008/06/18
817 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
819 --- 3.0.32 2008/06/12
821 Fixed memory violation that could occur when decoding UTF-8. This bug
822 was only present in 3.0.30 of YAZ.
824 --- 3.0.30 2008/06/06
826 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
827 GNU TLS is used by default (if found).
829 yaz-ztest returns OPAC records if a client asks for OPAC.
831 Improved speed of MARC-8 encoding.
833 Added support for lossy and loss-less MARC-8 encoding.
835 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
837 Added new Windows Service wrapper (sc).
839 yaz-client's itemorder command may now send a file.
841 Fixed yaz-marcdump to allow the use of NS prefix for record element.
843 Added new function yaz_log_xml_errors.
845 Allow (but warn) unknown XML attributes in MARCXML parsing.
847 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
849 The UTF-8 to MARC-8 conversion now uses a different set of characters
850 for Greek symbols. Bug #2120.
852 --- 3.0.26 2008/02/21
854 Added yaz_daemon (daemon.h).
856 Fixed bug #2068: pkg-config trouble
858 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
860 --- 3.0.24 2008/01/28
862 Document --with-xml2 option.
864 Added OPAC XML XSD (etc/opacxml.xsd).
866 Allow glob mask for name attribute in retrieval element for the
867 generic frontend server's retrieval facility.
869 Changed yaz_poll_poll to return yaz_poll_except for all returned events
870 except POLLIN/POLLOUT.
872 Fixed error handling in cs_listen. Bug #2037.
874 --- 3.0.22 2008/01/20
876 Fixed version in yaz/yaz-version.h.
878 Fixed bug #2027: Crash when closing connection.
880 Changed configure so that ICU support is only enabled if only ICU
881 and Libxml2 is available (because the ICU chain is XML based).
883 --- 3.0.20 2008/01/15
885 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
886 is built. Only this DLL depends on the ICU runtime.
888 yaz-ziffy is no longer part of YAZ. It is distributed separately by
889 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
891 Changed license of CCL module to 'Revised BSD'. After consultation with
892 remaining members of the original EUROPAGATE consortium, we are re-issuing
893 the CCL module without a separate license. The software was developed by
894 Index Data as part of a research project. The special license was included
895 to help feed usage information back to the project consortium to support
896 project evaluation. At this time, the project consortium has long-since
897 disbanded, and the majority of the original principals have retired. At the
898 same time, we have significantly modified the software during the following
899 years, to the point where very practically no original code remains. To
900 simplify re-use of the software, we have contacted those members of the
901 consortium who could be reached, and agreed to re-issue the module as a
902 proper part of the YAZ package.
904 Tcl scripts uses /usr/bin/tclsh as preferred shell.
906 CQL closer to being version 1.2 compliant. CQL also allows free-form
907 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
910 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
911 bug could make Extended services handling crash in the ZOOM layer. This
912 bug was only present in YAZ 3.0.18.
914 --- 3.0.18 2007/12/19
916 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
919 yaz-marcdump reads and writes collection wrapped records.
921 Handle OPAC for record conversion module.
923 Fixes for ICU wrapper.
925 Allow ICU libs to be controlled with --with-icu .
927 --- 3.0.16 2007/11/12
929 Added yaz_poll which is a wrapper for select/poll. When poll is available
930 and non-buggy, it is used, by yaz_poll . This allows more than 1024
931 sockets to be in use.
933 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
934 functionality through an XML based configuration (ICU chain). This system
935 is useful for search facilities such as Pazpar2 and Zebra that needs to
936 perform tokenization of indexed material. The ICU code in a separate
937 library libyaz3_icu.a.
939 Added HTTP tunnel facility for COMSTACK, bug #1752.
940 This is a facility that allows a Web proxy, such as squid, to tunnel
941 Z39.50 traffic. This facility is "transparent" to must applications
942 using YAZ. It's enabled by using pseudo transport connect: followed by
943 the proxy address, followed by command, then follwed by he regular
944 "virtual" addresss. For example,
945 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
947 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
949 --- 3.0.14 2007/09/21
951 Fixed bad memory reference in ZOOM_record - cuased by member not being
952 initialized. This was a problem only in YAZ 3.0.12.
954 Fixed bug in conversion from MARC to XML: Non-XML characters in control
955 fields were not removed.
957 Changed the way C code is generated from codetables.xml. Made a MARC-8
958 conversion trie for each characterSet section rather than codeTable.
959 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
960 of codetables.xml from Larry Dixson, LOC. Bug #1464.
962 --- 3.0.12 2007/09/12
964 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
965 from ZOOM_record_error).
967 ZOOM C function ZOOM_record_get returns record schema for type="schema".
969 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
971 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
973 Better SRW-to-Bib-1 diagnostic mapping.
975 ZOOM C and yaz-client announces SRU version 1.2 by default.
977 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
980 Fixed in yaz_sru_decode to allow other version than 1.1.
982 --- 3.0.10 2007/08/22
984 Added support for SRU scan for ZOOM.
986 Added support for the use of the older versions or Extended Service
987 Update in ZOOM. To faciliate this, an option "updateVersion" may be
988 set to the version , 1=first, 2=second, 3=third. The third version is
989 what ZOOM C has used so far. And that, obviously, is the default.
991 Added support for CCL queries in Z39.50 queries sent to the GFS (and
992 therefore in Zebra and in SimpleServer-based applications). The new
993 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
994 qualifier file used to transform incoming CCL queries into Type-1 RPN,
995 which is passed into the back-end search callback function.
997 Added support for HTTP Basic authentication in clients: the SRU/W
998 codec encodes the username/password elements of the PDU structure
999 appropriately, and these may be set using the "user" and "password"
1000 options in ZOOM-C applications (the same options that are used for
1001 Z39.50 authentication).
1003 --- 3.0.8 2007/06/25
1005 Fixed bug #1208: SSL appears to be broken in ZOOM.
1007 Fixed bug #1206: Libxml2 include path weirdness.
1009 Added oid_name_to_dotstring.
1011 Allow elementSetName to be specified for ZOOM C record update.
1013 Allow waitAction to be specified for ZOOM C based for Extended Services.
1015 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1016 syntax OID. Bug introduced in YAZ 3 series.
1018 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1020 --- 3.0.6 2007/06/06
1022 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1023 directory. yaz-client now reads commands from file given by option -f
1024 if specified; then tries to read .yazclientrc in current directory.
1025 Failing that, it reads .yazclientrc from user's home directory.
1027 Added support for correlationInfo Note and ID for Record Update via
1030 Added yaz-client command querycharset which specifies character set for
1031 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1032 (termListAndStartPoint).
1034 Charset ISO5428:1984 is an alias for ISO5428-1984.
1036 Implemented a way to perform scan in a result set using Z39.50. This
1037 is achieved by attaching the result set name in the characterInfo
1038 (type InternationalString) of OtherInformation in the Scan Request PDU.
1039 The result set is identified in the otherinformation by the new OID:
1040 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1041 This allows for scan in result set and faceted search . Zebra did some
1042 of this in the APT term using attribute type 8 and value being result
1043 set. Using the OtherInformation approach for this is cleaner and easier
1044 to work with in proxies and the like. This facility can be used in
1045 yaz-client using new command setscan which takes a result set as first
1046 argument, start position (APT) as second.
1048 Changed decoding of SRU XML packed records to deal with servers that
1049 have recordData with XML data with multiple root nodes. Also make
1050 comparison for recordPacking case insensitive. Again, one server
1051 returns "XML" where others return "xml".
1053 For SRU responses allow Content-Type application/xml as well as text/xml.
1055 --- 3.0.4 2007/05/21
1057 Fixed bug in character set conversion of BER strings. Bug introduced
1060 --- 3.0.2 2007/05/08
1062 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1064 For OID class, use oid_class consistently.
1066 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1069 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1070 character set for bibliographic information interchange". By Giannis Kosmas.
1072 Added documentation on new OID API.
1074 --- 3.0.0 2007/05/02
1076 Changes to generic frontend server interface: added new member
1077 'query_charset' for bend_initrequest structure. A backend init handler
1078 should set this member to its native character set for query terms.
1079 When defined, the frontend server logic will announce this character set
1080 to a client if the negotiationModel bit is set by the client. All server
1081 implementors are encouraged to specify this. If a backend server does not
1082 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1084 Added CCL utility to remove terms (stop words) from resulting RPN
1085 tree. This is handled by functions with prefix ccl_stop_words_ .
1087 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1088 terms in RPN queries.
1090 Clean-up the CCL API. Moved some internal structures from ccl.h to
1091 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1092 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1093 This is replaced by ccl_parser_find_str which takes a string instead.
1095 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1096 libyaz.la is the core of YAZ except the generic frontend server and
1097 does not depend on POSIX threads anymore. libyaz_server.la is the
1098 generic frontend server facilities and uses POSIX thread functionality
1099 if available. The libyaz.la no longer depends on POSIX threads because
1100 the number of global structures is limited. NMEM no longer re-uses blocks
1101 between threads ; it simply free's memory immediately but allocates in
1102 "large" chunks as usual. We don't expect any performance penalties
1103 because of this. The yaz_log system is still using a global log_level so
1104 caution must be taken when modifying it with yaz_log_init_.. +
1105 yaz_log_mask_str. This, however, should not cause any trouble because
1106 these functions are called during initialization of application code
1107 anyway. `yaz-config --libs server` returns libs for server applications;
1108 `yaz-config --libs` returns libs for non-server applications.
1110 New OID database - with public definitions in oid_db.h. Removed old OID
1111 database including the head oid.h and definitions such as enum oid_value
1112 and struct oident. The new OID database uses the same string names as
1113 before but the 'protocol' is gone. There are now only two representations
1114 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1115 converts from string to OID; functions with prefix yaz_oid_to_string
1116 converts the other way.
1118 Change to emit_term() in CQL-to-PQF query translation: when a term has
1119 the /regexp relation modifier, do not process it for leading and
1120 trailing "^" and "*", which have quite different meanings in regular
1123 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1124 write handlers no longer carries a 'last' parameter. This will make
1125 yaz_iconv flush "less" characters. A flush is performed by call to
1126 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1128 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1129 removed, because function yaz_query_to_wrbuf does the same.
1131 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1132 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1134 Deprecated MARC utility functions removed.
1136 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1139 Branch split: YAZ_2_1_55_branch
1141 --- 2.1.54 2007/03/16
1143 Fix to ZOOM-C so that transparent reconnection is properly handled on
1144 connections that are in asynchronous mode.
1146 Fixed compilation on OpenBSD 4.0.
1148 Large strings in GRS-1 records are now properly displayed in yaz-client.
1150 Added character conversion support for "advancegreek"; based on patch from
1153 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1154 sequence is met. Before the error was not set so it would be unknown.
1156 Adjust yaz-marcdump MARC reader so that it skips until record separator
1159 --- 2.1.52 2007/03/07
1161 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1162 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1163 fd_set structure used as a bitmask for the FDs to be selected on.
1165 Using ACX_PTHREAD macro to check for POSIX threads.
1167 Fixed have-vsnprintf check.
1169 --- 2.1.50 2007/02/23
1171 Fixes for configure on BSD. Bug #900.
1173 Added snprintf/vsnprintf wrappers for systems that don't have
1174 limits (heavens forbid).
1176 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1177 created before all previous tasks were completed and removed from the
1178 task queue, the new task could be removed by a mistake.
1180 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1182 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1184 Fixed bug #832: Problem with MARC/charset in yaz-client.
1186 Fixed bug #668: save command line history for yaz-client.
1188 Fixed bug #830: pkg-config support.
1190 --- 2.1.48 2007/01/23
1192 Extended ZOOM result set options with two options that may be read by
1193 a client: resultSetStatus and presentStatus with values as specified for
1195 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1197 Fixed bug #827: Using SSL fails on Debian etch.
1199 Fixed bug #826: Weird looking chars for set of MARC records.
1201 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1202 that is treated as an ItemOrder with itemRequest being an XML document
1203 external. The value of "doc" is the content.
1205 Extended the GFS search facility. New member of bend_search_rr
1206 'estimated_hit_count' signals that hits is known to be an estmate
1207 (higher or lower than real hit count). New member 'partial_resultset'
1208 signals that the search was partial (hit count is lower or equal than
1209 real hit count). For Z39.50, the information is stored in resultSetStatus
1210 member of SearchResponse APDU. For SRU, the information is signalled
1211 via SRU diagnostic 59: "Result set created with valid partial results
1214 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1216 --- 2.1.46 2007/01/13
1218 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1220 Added ZOOM_connection_peek_event.
1222 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1223 the following new functions:
1224 ZOOM_event_nonblock, ZOOM_connection_process,
1225 ZOOM_connection_get_{socket,mask,timeout},
1226 ZOOM_connection_fire_event_{timeout,socket}.
1227 The existing blocking event handler, ZOOM_event, is a wrapper for the
1228 + blocking ZOOM_event_sys_{poll,select}.
1230 Implemented function ccl_xml_config which parses XML version of CCL
1231 configuration (bug #798).
1233 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1235 Added timings utility (yaz/timing.h)
1237 --- 2.1.44 2007/01/03
1239 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1242 Fixed bug #779: Rotation of apdu.log fails.
1244 Fixed for character set conversions:
1245 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1246 Honor G1 set in MARC-8 decoding.
1248 --- 2.1.42 2006/12/17
1250 Fixed bug #775: char conversion does not handle Alternative UTF-8
1253 Implemented function yaz_marc_read_line which parses MARC line format
1254 records. There is a wealth of formats out there. So far, this function
1255 reads line records produced by yaz_marc_write_line.
1257 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1258 more generic and easier to remember(!) options: -i format and -o format
1259 which specifies input format and output format respectively - where
1260 format is one of "marc", "marcxml", "line", "marcxchange".
1262 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1263 does not print anything except warnings for records.
1265 For yaz-marcdump, added support for MARC split into files (-s) with a given
1268 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1269 spec, at http://www.loc.gov/standards/sru/record-update/
1270 This has changed the binary layout of the following structs:
1271 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1272 bend_update_rr . Patch by Ko van der Sloot.
1274 Added GFS utility function bend_assoc_is_alive which returns 1 if
1275 association is still alive (client is connected); 0 otherwise (client
1276 closed connection). This allows busy servers to stop working for
1279 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1280 been a separate piece of software. This version of ziffy has been modified
1281 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1283 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1285 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1286 Client code may now interrogate options such as "init_opt_sort" to
1287 find out whether the server claims to support various options.
1289 --- 2.1.40 2006/11/27
1291 Added utilities yaz_{set,get}_esn to set/get element set name from
1294 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1295 of YAZ and has been so since YAZ 2.1.10.
1297 Implemented ZOOM_record_error which returns error information for
1298 record (surrogate diagnostic).
1300 --- 2.1.38 2006/10/31
1302 Updates for SRU Update by Ko van der Sloot:
1303 1. Changed name from "operation" to "action"
1304 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1305 versions in the code, marked as 'backward compatible'.
1306 3. Added diagnostics for SRU Update.
1308 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1310 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1312 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1314 For GFS, fixed problem with SRU diagnostic 'First record position out of
1315 range' being issued for 0 hits.
1317 zoomtst10 part of Windows Build.
1319 --- 2.1.36 2006/10/13
1321 Implemented yaz_filepath_comp which splits a path into file path
1322 components (required by Zebra 2.0.3+).
1324 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1325 BSD inspired license until now so this should not have any real impact on
1326 anybody. See http://www.opensource.org/licenses/bsd-license.php
1328 Fixed bug #687: Missing log lines.
1330 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1333 Fixed bug #689: SRU diagnostics to be added.
1335 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1336 whether a connection is idle (no more work do do).
1338 --- 2.1.34 2006/10/04
1340 Change type of optval from long to int for invocation of setsockopt with
1341 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1343 Added support for specifying the max log file size for the Generic
1344 Frontend Server. The size is given with option -r.
1346 --- 2.1.32 2006/09/21
1348 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1350 --- 2.1.30 2006/09/17
1352 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1355 Fixed bug in Generic Frontend Server that could cause a server to stop
1356 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1358 For the generic frontend server, the maximum record size is used as maximum
1359 size of incoming packages (SRU + Z39.50). The value until was previously
1360 only used in Z39.50 Init negotiation and, later, in a session controlled
1361 sizes of records returned. This is controlled using -k option. It can be
1362 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1364 --- 2.1.28 2006/09/04
1366 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1369 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1371 New option for yaz-marcdump -lpos=value which allows setting a portion
1372 of MARC header to a certain value.
1374 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1376 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1377 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1379 --- 2.1.26 2006/08/15
1381 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1384 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1386 --- 2.1.24 2006/08/08
1388 Fixed MARC ISO2709 encoding routines to deal with character set
1391 Minor changes to GFS logging. Database included in search request log
1394 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1395 cached/multiple records.
1397 Shared libraries are built by default on Unix+configure.
1399 Changed cql2pqf transformation to use a different evaluation order. The
1400 new order is: always, relation, structure, position, truncation, index
1401 and relationModifier. Old order was: always, relation, relationModifier,
1402 structure, index, position, truncation. Note that the the latter ones
1403 override former ones for identical attributes.. The new scheme means that
1404 it is possible to override any existing attribute with a relationModifier.
1405 And also that it is possible to override everything for the index rule
1406 (except the ones listed in relationModifier). No order is perfect but this
1407 one, we believe, covers more real cases.. The "always" should have been
1408 called "default", since the attributes there can be overridden with all
1411 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1412 compilation phase, but also for yaz-config --cflags output. This allows
1413 us to have public headers with Libxml2 stuff in them . It should also,
1414 eventually, make Libxml2 checks redundant in packages using YAZ, such
1417 --- 2.1.22 2006/06/15
1419 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1420 stored in uri, message and details.. Previously diagnostics were stored
1421 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1422 compatibility.. but he's probably the only one affected, so.
1424 Added support for CCL, compiled on the client side, in ZOOM-C. This
1425 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1426 input; the resulting query objects can be used for for searching with
1427 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1429 YAZ' configure searches for OpenSSL by default.
1431 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1432 SL_CTX_use_certificate_file. See
1433 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1434 for more info. Thanks to Ko van der Sloot.
1436 --- 2.1.20 2006/06/02
1438 Bug #600: SRU GET, POST support for yaz-client. Introduced
1439 command 'sru' which selects method SOAP/GET/POST.
1441 Allow missingValueAction to be specified for the sortspec string -
1442 function yaz_sort_spec. By default, the missing value action is null.
1443 Use ! to specify "abort". Use = followed by stringvalue to specify default
1446 Ensured that Present-handler (if defined) is called in GFS before any call to
1447 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1448 searchRetrieve requests.
1450 Documentation for YAZ is now based on the Docbook XML/XSLT using
1451 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1452 is no longer depending on jade/openjade or docbook-to-man scripts.
1453 PDF is no longer part of the distribution - but can optionally be
1454 made using DSSSL/jadetex or FOP.
1456 Added retrieval handling support in Generic Frontend Server to support
1457 conversion between MARC/XML as well as XSLTtransforms. See
1458 etc/yazgfs.xml for an example.
1460 Added Authentication support to Generic Frontend Server in SRU
1461 mode. Authentication using HTTP Basic is supported, as is the use
1462 of 'x-username' and 'x-password' parameters in the request itself.
1464 Added support for a new character set MARC8s identical to MARC8 except
1465 that it converts combined characters to single Unicode characters in the
1466 Latin-1 range (when possible).
1468 --- 2.1.18 2006/04/24
1470 ASN.1 compiler 0.4: generates brief Doxygen file header for
1471 generated .h/.c files.
1473 Utility yaz_iconv now supports conversion to MARC-8.
1475 New facilities for the MARC module. The reading - and writing of
1476 content are separate methods for the yaz_marc_t handle. The following
1477 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1478 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1479 format). Write functions have prefix yaz_marc_write_.. The existing
1480 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1481 available. Removed support for OAI-MARC and simplexml (not the
1482 simplexml from PHP5).
1484 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1485 to be returned for this connection.
1487 --- 2.1.16 2006/03/31
1489 Allow multiple languages and charsets to be specified with
1490 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1491 negcharset iso-8859-1,utf-8
1493 Translation of proximity nodes from CQL into PQF now works.
1495 Moved to automake 1.8, 1.9.
1497 Added function yaz_log_set_handler which allows a log handler to be
1498 installed. This handler will be called for all log messages. Output
1499 to file is also produced; but that can be disabled by passing NULL
1500 fname to yaz_log_init_file.
1502 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1504 For SRW (including GFS), accept application/soap+xml as content-type
1507 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1508 produces NO stylesheet reference even if a default stylesheet is specified
1511 --- 2.1.14 2006/03/14
1513 Updated Windows package to include yazd.dll + yazd.lib for the
1514 Development component.
1516 If the environment variable YAZ_LOG is set, then it is used as a
1517 string indicating the default level of logging to use if not
1518 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1519 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1520 used as before. So, for example, to omit warnings from YAZ logging,
1521 export YAZ_LOG=-warn
1523 cql_transform() now map structure and other attributes before indexes,
1524 so that index-specific structures and other attributes can override
1525 defaults. So now a combination of mapping specifications such as:
1527 index.dc.date = 1=date-modified 4=5
1528 does the right thing.
1530 cql_transform() now also respects the "always" mapping specification,
1531 which establishes an initial set of attributes to be used for all
1532 terms except where overridden by more specific attributes associated
1533 with the index, relation or modifier.
1535 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1536 which mode to use; one of "post", "get" or "soap" (SRW, default).
1538 Fixes for yaz_iconv routines: changed trie-based character set conversions
1539 to use only non-negative values for bit fields due to Sun's C compiler not
1540 supporting negative values.
1542 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1543 sequences where not read correctly. Fix by Rustam Usmanov.
1545 Updated win/makefile to use options, settings which makes things
1546 compile with VS C 2005.
1548 --- 2.1.12 2006/02/01
1550 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1552 In ZOOM socket code, use select instead of poll on MacOSX.
1554 ZOOM-C now support client-side compilation of CQL into RPN that is
1555 sent to the server, enabling CQL to be used against all Z39.50
1556 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1557 ZOOM_query object, and submit it using ZOOM_connection_search().
1558 The CQL-to-RPN translation uses a configuration file, the name of
1559 which must be specified in the Connection's "cqlfile" option.
1561 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1562 function, which takes as its start-term parameter a ZOOM_query object
1563 (which may have had either CQL or RPN set into it).
1566 --- 2.1.10 2005/11/29
1568 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1569 GFS to support this as well. Backend handler, bend_srw_update, does the
1570 update work. Code contributed by Ko van der Sloot.
1572 Allow retrieval of Search Result-1 information in ZOOM by the use of
1573 options that are attached to a result set. ZOOM documentation updated
1576 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1577 UTF-8 conversion. Patch by Raj Patel.
1579 Added option -m to GFS to control formatting of timestamps in log file.
1581 Added 'exit' as synonym for 'quit' in yaz-client
1583 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1584 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1585 for the new members. Patch by Ko van der Sloot.
1587 Added support for SRU POST. It is supported for content-type
1588 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1590 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1591 Instead make the library libyaz.la multi-threaded. Threading as a whole
1592 can still be disabled by configure option --disable-threads. Previosly,
1593 with older GLIBCs there were problems with MT libs under Apache. This
1594 has now been fixed a long time ago.
1596 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1599 CQL module modified to be case insensitive for relations/indexes/operations.
1601 Fixed bug in CQL transform code: incorrect value relationModifieder
1604 Added 'show all' command for yaz-client which retrieves all results
1607 Added new yaz-client, xmles, which takes a (private) OID and
1608 a document to be sent as an extended service request.
1610 Describe new yaz-client commands wait_response and set_auto_wait.
1612 Increase TCP/IP listener backlog from 3 (which I am guessing was
1613 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1614 that the socket will queue as many incoming connections as it's able
1615 to handle ongoing connections. In other words, it will never now
1616 refuse a connection that it would be able to handle merely because
1617 it's not got around to accepting() enough of the pending connections
1618 yet. This is the behaviour anyway under Linux, where the listen()
1619 argument is ignored; but not under BSD and on systems such as
1620 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1621 YAZ-based servers should now be uniform across operating systems in
1624 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1625 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1626 This allows yaz-marcdump to read large MARC batches (>2 GB).
1628 Modified all YAZ source files - except the source which is auto-generated
1629 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1632 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1633 corresponding to the existing *_setl() function. These allow option
1634 values containing arbitrary valuues.
1636 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1637 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1638 except that it returns an indicator of whether or not the sort
1639 criterion was accepted (0 for OK, -1 for invalid).
1641 --- 2.1.8 2005/06/07
1643 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1644 MARC output rather than returning "new" buffer.
1646 yaz-client warns about unknown init options.
1648 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1650 --- 2.1.6 2005/05/24
1652 Added support for SRW sort in Generic Frontend Server. Patch
1653 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1654 sortKeys - or NULL if none is provided.
1656 Fixed bug #307: It was impossible to specify indefinite/no timeout
1657 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1660 Added support for multiple languages and charsets to be specified in
1661 ZOOM. Each charset/language is separated by a blank. If negotiation is
1662 in effect in init-response, Option
1663 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1664 Code based on patch by Vasiliy Osadchuk.
1666 Fixed bug #306: infinite recursion that occurred when calling
1667 yaz_log_level_init as the first call (before other log level or
1670 Fixed bug in scan handling in front end server: if preferred-Position-In-
1671 Response was non-present, a NULL pointer referece was performed.
1673 --- 2.1.4 2005/04/26
1675 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1676 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1677 now defined for all those error codes. So instead of putting 109 in
1678 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1679 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1681 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1684 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1686 Program yaz-client now exits and produces an error message if multiple
1687 Z39.50 servers are specified on the command line (none or one allowed
1690 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1693 --- 2.1.2 2005/03/16
1695 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1697 Fixed bug #272: Preserve spacing for CCL terms.
1699 --- 2.1.0 2005/03/14
1701 Added support for virtual hosts and multiple backend servers for
1702 the YAZ frontend server. The configution is XML based and
1703 support specificition of CQL to RPN mappings and explain information.
1704 See section "Virtual Hosts" in the YAZ manual.
1706 Extended OPAC display utility. OPAC display utility renders
1707 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1708 to supplement yaz_marc_decode_wrbuf.
1710 Fixed a bug in MARC decoder that could caused it to crash for some
1711 invalid MARC records. More diagnostics and warnings where added in
1712 XML output (warnings, etc are stored in comments).
1714 --- 2.0.34 2005/02/08
1716 Fixes for UNIX domain sockets. Bug #261.
1718 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1720 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1721 Added yaz_marc_subfield_str which defines subfield lead string which is
1722 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1723 yaz_marc_endline_str which defines end of fields string used in
1724 YAZ_MARC_LINE format. Default string is newline.
1726 Experimental support for MarcXChange. This format can be produced
1727 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1728 http://www.bs.dk/standards/MarcXchange.xsd
1730 Added yaz-client commands scansize that sets maximum number of
1731 entries to be returned by scan.
1733 --- 2.0.32 2005/01/11
1735 Added support for SRW scan in yaz-client and Generic Frontend Server.
1737 * Added whereInList member to SRW Scan Term.
1739 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1741 Fixed NMEM system to return aligned blocks on the smallest boundaries
1742 that are suitably aligned for all possible types on the particular
1743 architecture YAZ is being built for.
1745 --- 2.0.30 2005/01/04
1747 Fixed numerious warnings that was issued with newer versions of GCC.
1749 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1750 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1753 Make YAZ Generic Frontend Server slightly faster.
1755 Enhance (and reduce) logging for Generic Frontend Server.
1757 Revert YAZ log system so that it flushes every write operation
1758 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1760 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1761 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1762 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1763 will effectively disable old definitions.
1765 --- 2.0.28 2004/11/09
1767 Added yaz_log_time_format which specifies log format using
1770 Added yaz_log_module_level which returns mask for a module. Value
1771 is non-zero mask a if module is enabled; zero if disabled.
1773 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1774 in include/yaz/cql.h.
1776 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1778 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1780 Fixed bug #172: RPM builds does not enable SSL.
1782 Doxyfile.in part of dist. Doxyfile generated by configure.
1784 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1785 are given and the corresponding component does not exist.
1787 Extend CCL documentation in YAZ reference. Describe r=r.
1789 --- 2.0.26 2004/10/01
1791 Fixed MARC->MARCXML conversion to properly deal with
1792 fields, subfields, indicators having non-ASCII characters.
1794 Fixed MARC->MARCXML conversion so that ASCII control characters
1795 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1798 Added YAZ GFS support for conversion from Z39.50 surrogate
1799 diagnostics to SRW surrogate diagnostics.
1801 Bug fix: YAZ GFS did not return schema in explainResponse.
1803 --- 2.0.25 2004/09/30
1805 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1806 now converts recordSchema to elementSetName as well as schema URI.
1808 Fixed bug in COMSTACK that prevented HTTP request packages from being
1811 --- 2.0.24 2004/09/29
1813 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1814 does not require white-space before and after the dash in a range, e.g.
1815 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1818 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1819 due to new GCC removing "redundant" code.
1821 Added yaz-client commands scanpos and scanstep that sets preferred
1822 position and step-size for scan.
1824 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1826 Added CCL utility ccl_qual_buf which parses one or more CCL
1827 spec lines in a buffer.
1829 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1830 of name and value - ignoring empty lines and comments.
1832 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1834 Added odr_get_element_path which returns current element path for an
1835 ODR handle. This utility is useful in error handling or user-defined
1838 Added ODR_PRINT utility odr_set_stream which is is a more generic
1839 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1840 to a write function and pointer to close function. The close function - if
1841 non-NULL - will be called during odr_destroy.
1843 Fixed bug in CCL parser where truncation char was not removed from
1844 right side when truncation=both was in effect.
1846 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1849 --- 2.0.23 2004/08/11
1851 Fix buffer overrun in CQL parser when dealing with proximity (%).
1853 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1854 to UTF-8/UCS conversion is now only based on codetables.xml.
1856 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1858 --- 2.0.22 2004/08/06
1860 Add support for more "commit changes" in ZOOM (uses Extended Services).
1862 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1865 Yet another small fix for configure of SSL.
1867 --- 2.0.21 2004/05/14
1869 Fix SSL libs for configure when --with-openssl=DIR is given.
1871 --- 2.0.20 2004/05/10
1873 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1875 SSL comstack now uses yaz.pem certificate file on server side
1876 by default. Certificate filename can be configured by calling
1877 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1879 Fix bug regarding multiple calls to ZOOM_connection_connect.
1881 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1883 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1884 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1886 ZOOM now allows inspection of X509 peer certificate for verification.
1887 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1889 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1890 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1891 as "modular" but it simplifies things.
1893 Added cs_get_peer_certificate to that returns peer X509 PEM.
1895 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1896 NULL if SSL is unavailable.
1898 Documentation about MARC decoding tools.
1900 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1902 --- 2.0.19 2004/03/30
1904 Rename CHANGELOG to NEWS to follow GNU style packing.
1906 Fix bug with missing initialization of member in init_diagnostics.
1907 This bug affects threaded version of GFS server.
1909 --- 2.0.18 2004/03/20
1911 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1914 Ensure zlib.dll is packed with Windows install.
1916 --- 2.0.17 2004/03/17
1918 Fix encoding of xsd:string to use text instead of CDATA.
1920 Fix endless loop in CQL parser with unbalanced ".
1922 Use a more compact way to store MARC-8 conversion tables.
1924 --- 2.0.16 2004/03/16 Debian only
1926 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1929 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1934 --- 2.0.15 2004/03/01
1936 Another fix for decoding of XML packed records.
1938 --- 2.0.14 2004/02/25
1940 Fixes for Chunked encoding. White space not ignored after length spec.
1942 Update NS and use default NS for SRW diagnostic elements.
1944 --- 2.0.13 2004/02/23
1946 Implement ZOOM_resultset_cache_reset which resets record cache.
1948 Implement ZOOM_resultset_sort which sorts a result set.
1950 Implement chunked HTTP transfer.
1952 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1954 --- 2.0.12 2004/02/16
1956 Added member 'schema' to bend_explain_rr structure so that backend
1957 can specify explain record identifier. Defaults to Zeerex 2.0.
1959 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1961 --- 2.0.11 2004/02/16
1963 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1966 Added init command for yaz-client which sends "extra" init request.
1968 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1969 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1971 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1973 Make ZOOM error code for "invalid query".
1975 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1977 --- 2.0.10 2004/02/05
1979 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1982 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1984 Added option -p <file> to make Generic Frontend Server to write PID file.
1986 Added option -D to put Generic Frontend Server in background on its own.
1988 Make ZOOM C recognize option "password". If unset, "pass" is used
1989 (for backwards compatibility).
1991 Fixed a bug in Generic Frontend Server that could make it crash if a
1992 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1995 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1996 Must be issued before open, in order to be in effect.
1998 --- 2.0.9-6 2004/01/12 Debian/Windows
2000 Make the SRU server more picky WRT unknown params, etc.
2002 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2004 New YAZ client command, options, that sets Z39.50 options.
2006 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2007 options from a string of tokens (one token for each option bit).
2009 Update SRW diagnostic code messages.
2011 --- 2.0.9-5 2004/01/07 Debian/Windows
2013 Handle user defined stylesheet for SRW/SRU.
2015 --- 2.0.9-4 2004/01/06 Debian/Windows
2017 Fix bug in decoding of Content-Length.
2019 --- 2.0.9-3 2004/01/06 Debian/Windows
2021 Fix a bug with decoding of XML packed records.
2023 --- 2.0.9-2 2004/01/05 Debian only
2025 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2027 Fix bug in SRW/SRU diagnostics decoding.
2029 --- 2.0.9 2004/01/05
2031 Fixed bug in Generic Frontend Server which could drop records exceeding
2032 preferred message size. Reported and fixed by Irina Dijour.
2034 Fixed calculation of package size for structured records in Generic
2035 Frontend Server. Reported and fixed by Irina Dijour.
2037 Fixed namespace for SRW/SRU diagnostics.
2039 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2041 --- 2.0.8 2003/12/22
2043 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2044 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2047 CQL changes to reflect recent changes to the specification:
2048 * Documentation talks about context sets instead of index sets.
2049 * Documentation talks about indexes instead of qualifiers.
2050 * The CQL-to-PQF transformer's configuration file now uses
2051 "index.set.name = <attributes>" instead of the old form
2052 "qualifier.set.name = <attributes>". (Both forms are still
2053 understood but the latter is deprecated.)
2054 * CQL terms with no explicit index specified are now interpreted as
2055 cql.serverChoice instead of srw.serverChoice (which of course
2056 behaves exactly the same.)
2058 --- 2.0.7 2003/12/16
2060 MARC conversion can now generate ISO2709 output in another
2061 character set. yaz-marcdump uses this facility if you invoke it
2064 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2065 functions from there can be used from C++.
2067 --- 2.0.6 2003/12/04
2069 Frontend server now transfers memory from decoded packages to stream
2072 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2073 references to show up.
2075 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2076 the ZOOM Abstract API. The older names for the same options are still
2077 also supported for the benefit of old applications.
2079 ZOOM-C supports "implementationId" and "implementationVersion" options
2080 to go along with "implementationName". These allow the user code to
2081 specify identification strings to be sent to servers.
2082 Add OID for the new ExtLite attribute set.
2084 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2085 as requested/supplid by Ere Maijala <ere@atp.fi>
2087 For generic frontend server, reverse the order of
2088 "toolkit-supplied / application-supplied" strings sent as implementationId,
2089 Name and Version. Also, remove the spaces around the slash. This brings
2090 the GFS in line with the behaviour of ZOOM-C on the client side.
2092 Add function ZOOM_scanset_display_term.
2094 yaz-client shows scan displayTerm if present.
2096 Utility yaz-iconv is now installed by default along with the man page
2099 Extend configure check for OpenSSL to use pkg-config where available (such
2102 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2103 server to specify uid/gid/mask for socket using the format
2104 unix:[user=uid,][group=gid,][umask=mask,]file=path
2105 If file= is omitted the existing format is assumed, e.g.
2107 in which case the mask is 0666 (rw for everybody).
2109 Major restructure of YAZ source. All source in libyaz is in src directory.
2110 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2111 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2113 Added man page for utility yaz-marcdump (used to be called marcdump).
2114 yaz-marcdump is installed by 'make install'.
2116 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2117 of incoming package failed.
2119 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2121 Change prototype of odr_perror: add const to message string.
2123 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2125 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2126 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2127 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2128 DNS lookup. There should not be any compatibility problems with this
2129 assuming that blocking=1 or 0 is used.
2131 Fix bad reference in UNIX comstack in function cs_addrstr.
2133 Fix for compilation on AIX.
2135 The generic front-end server (server/seshigh.c) now supports returning
2136 Init diagnostics to the client in User-information-field, in
2137 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2140 --- 2.0.4 2003/09/04
2142 Allow any CQL relation (not just all,any,exact,scr).
2144 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2145 that features the same UI.
2147 Implemented command update0 in YAZ client which is equivalent to
2148 update but uses old of Ext Update ASN.1.
2150 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2151 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2152 Previously no OID was used for this info.
2154 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2155 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2156 returns 'malformed search term' otherwise.
2158 SortResponse member resultCount now set to NULL in sort handler of
2161 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2164 Add three new utility functions for translating OIDs between various
2165 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2166 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2167 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2168 char *oid_to_dotstring(const int *oid, char *oidbuf);
2169 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2171 Reverted modifications for ES Update definition for z_IU0Update
2172 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2173 is back to YAZ 2.0.2.
2175 String value attributes for CCL parser.
2177 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2178 which their FirstSearch server returns in Init responses, sometimes
2179 carrying useful diagnostic information when Init fails. This has the
2180 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2181 "z39.50/oclcui.asn", where its definition is somewhat different from
2182 what OCLC document on their web-site, as required to interoperate with
2185 Support for anonymous authentication in yaz-client. Use the command
2188 * Fix the OID of the Index Data-local "admin" Extended Service from
2189 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2190 the 1000, which indicates a locally-defined OID, was a mistake.
2192 --- 2.0.3 2003/06/20
2194 Fix CCL directive @case handling so that it affects string match for
2195 both CCL keywords and qualifiers.
2197 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2198 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2199 Decoder has been updated with ASN.1 changes as listed in
2200 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2201 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2202 z_IUUpdate, remains unchanged.
2204 ZOOM_record_get may now return a record in a specific character set.
2205 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2206 "from" is the character set of record as returned by target. "to" is
2207 the character set to be returned. If omitted, "to" is UTF-8.
2209 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2211 New ODR utility, odr_getelement, which returns name of element for
2212 which encoding/decoding failed.
2214 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2215 in cases where a required element was omitted.
2217 Bug fix: some MARC8 sequences were not converted.
2219 New ZOOM option "step" which specifies number of records to be
2220 retrieved in one chunk. Used in conjunction with "start" and "count".
2222 SRW support for yaz-client. Use scheme http: to use it, e.g.
2225 yaz-client no longer does (un)intelligent character set conversions
2226 by default. Can be enabled with charset and marc_charset commands.
2228 xmalloc trace fix for 64-bit systems such as DEC alpha.
2230 Solaris 2.6 compile fix.
2232 New function, cql_strerror() translates SRW error codes, as returned
2233 by cql_transform_error(), into human-readable English strings. Used
2234 in yaz-client diagnostics when appropriate.
2236 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2237 converts it into a type-1 query which is sent to the server. This
2238 makes CQL available for use with all Z-servers, as opposed to the tiny
2239 minority that can handle CQL queries themselves.
2241 --- 2.0.2 2003/04/28
2243 New Debian package layout similar to the Redhat Package layout.
2245 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2246 and search result respectively.
2248 --- 2.0.1 2003/04/25
2250 Redhat package is now several packages: libyaz (runtime libraries),
2251 libyaz-devel (development and documentation, and yaz (utility programs).
2252 Package spec file by Morten Bogeskov.
2254 New member 'schema' in struct bend_fetch_rr which the name of requested
2255 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2256 handler MAY set this to reflect the schema of the returned record.
2258 New member 'display_term' in struct scan_entry. GFS now sets member entries
2259 and allocates scan entries to be filled by user scan handler. In previous
2260 version, entries member was allocated by the scan handler. That still works,
2261 but the GFS will ignore member display_term - assuming it was NOT set by
2262 the handler. The fact that the GFS now allocates the entries both allows
2263 for new members and makes a scan handler easier to write.
2265 Fix CQL lex buffer overflow.
2267 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2268 SRU default recordPacking is string.
2270 SRU protocol support for frontend server.
2272 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2274 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2276 Added scan for the ZOOM shell (zoomsh).
2280 * String Identifers for Schemas (Amendment 5).
2281 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2282 Old definition for schema
2283 Odr_oid *schema; /* OPT */
2288 Z_InternationalString *uri;
2289 #define Z_Schema_oid 1
2290 #define Z_Schema_uri 2
2293 * resultCount parameter to Sort Response (Amendment 1).
2294 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2296 Support for SRW 1.0 over HTTP. This is an optional feature and
2297 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2300 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2301 on the same port. SRW SearchRetrieveRequests are mapped
2302 to bend_init,bend_search,bend_fetch,bend_close.
2304 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2306 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2307 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2309 ZOOM connections are SRW based if schem http is used for hostname
2310 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2311 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2313 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2314 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2315 distance=n, order=true/false, relation=le, prox unit=word. If
2316 n is omitted, distance 1 is used.
2318 Fixed problem with C compiler include path in wrong order.
2320 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2321 on Solaris. Patch from Ko van der Sloot.
2323 New MARC decode API. All new functions operate on a yaz_marc_t
2324 handle. The most important new functions are: yaz_marc_create,
2325 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2326 decode and destroy respectively. Decoder can produce formats
2327 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2328 include/yaz/marcdisp.h.
2330 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2331 to UTF-8, UCS-32, wchar_t or Latin-1.
2333 * Prototypes for yaz_iconv_-functions moved to separate header
2334 include/yaz/yaz-iconv.h.
2336 Make a few private functions 'static' in unix.c. This prevents
2337 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2339 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2340 are set when Init Response is received.
2342 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2343 but returns diagnostic set as well.
2345 New function yaz_strerror which is a portable wrapper for
2346 strerror/strerror_r/GetLastMessage.
2348 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2349 is returned for MARC. If type is "oai", then OAI MARC is returned.
2351 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2354 --- 1.9.2 2002/11/26
2356 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2358 Fix bad race conditions on SIGTERM and terminate gracefully in
2361 Move retrieval (data1) module to Zebra since nobody seems to be
2364 Add GRS-1 render for ZOOM using same format as yaz-client.
2366 --- 1.9.1 2002/10/05
2368 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2370 Fix broken ESpec handling in data1 module.
2372 SGML reader parses comments and makes them part of the data1 tree.
2374 Added several type casts so that YAZ compiles as C++ code.
2376 ZOOM didn't handle PDU encoding failures properly.
2378 Added more Bib-1 diagnostics (approved extensions).
2380 GNU configure: better check for iconv.
2382 More portable use of accept, getpeername. Check for socklen_t. Use
2383 int/size_t if socklen_t is not defined.
2387 PQF parser rejects bad queries - including those with extra
2388 characters in them. PQF parser used to silently ignore that.
2389 Cleaner API for PQF added, which allows you to get detailed
2390 error information for bad queries (see yaz/pquery.h).
2392 Fixed bug in ZOOM_record_get for type "database".
2394 Implemented mini iconv library supporting conversions between
2395 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2397 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2399 --- 1.8.9 2002/08/20
2401 Fixed ZOOM C record cache so that preferredRecordSyntax and
2402 elementSetName is used to check for already fetched records.
2404 --- 1.8.8 2002/08/02
2406 Added three members in bend_initrequest structure to facilitate
2407 character set negotiation.
2409 Fixed a bug in frontend server that could cause indefinite
2410 loops under rare conditions.
2412 Revised character set utilities (charneg.h) so that encoding
2413 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2415 For PQF, directive @term <type> sets term type for Scan/Search.
2416 Here <type> is general, string, numeric, null. The term type
2417 is inherited - just like @attr.
2419 New call odr_set_charset that sets character set conversion for
2420 international-strings on a ODR stream. Prototype is:
2421 int odr_set_charset(ODR o, const char *to, const char *from);
2422 The InternationalString is still represented as C string in YAZ
2423 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2424 won't). On the protocol level, you can use any encoding.
2426 Support for UNIX sockets in ZOOM.
2428 Solaris recv sometimes returns errno == ENOENT. It is treated as
2429 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2431 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2432 both client and server. Code by Morten Bogeskov.
2434 --- 1.8.7 2002/05/22
2436 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2437 that they can be used directly from Visual Basic. You must recompile
2438 your windows APP if you're using ZOOM.
2440 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2441 Commands "lang" and "charset" sets language and character set respectively.
2442 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2443 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2445 Attributes from multiple CCL fields may be OR'ed rather than merged
2446 using directive "@field or". Fields are still merged by default -
2447 equivalent to "@field merge".
2449 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2452 Fixed bug in zget for parameter ExtendedServicesResponse.
2456 --- 1.8.6 2002/03/25
2458 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2460 Client displays USR.1:SearchResult-1 (hits per term).
2462 Additional Search Info for search in Generic Frontend Server.
2464 Fixed CCL parsing of "field=s".
2466 WIN32 installer - using the excellent NSIS software from nullsoft.
2468 Fixed CCL parsing of "field = - <number>".
2470 Added function yaz_marc_decode that decodes MARC for line mode
2471 display or XML (similar to that used by JZKit).
2473 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2474 Z39.50. But ISO/ILL was, however.
2476 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2477 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

2482 --- 1.8.5 2002/02/03
2484 New YAZ client features: Command completion and new commands:
2485 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2486 Code provided by Jacob Poulsen.
2488 New call oid_trav, that visits all registered OIDs via callback.
2490 Function ZOOM_record_get now returns const char pointer rather than
2491 void pointer. It saves a lot of type casts.
2493 For YAZ client, command "auth" now allows you to set authentication
2494 in IdPass style. It is enabled when three tokens are given - order
2495 is user, group and password.
2497 Fix memory leaks in MARC record handling for ZOOM.
2499 New option for YAZ client, -k <kilobytes> that sets
2500 maximum record size. Similar to -k option for generic frontend
2501 server and yaz-ztest.
2503 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2505 Prefix query parser reports "fail" when bad attribute set is given.
2507 Fix in MARC decoder. Proximity logging. Fix for attribute set
2508 in scan handler for server. Patches by Shigeru Ishida.
2510 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2513 Configure option --with-openssl=<dir> now works when a directory is
2514 specified. Patch provided by Morten Bogeskov.
2516 New option for YAZ client, -u <auth>, that sets authentication.
2518 ZOOM fix: error information was sometimes "missing", since error
2519 was cleared/reset too when it shouldn't.
2521 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2523 --- 1.8.4 2002/01/04
2525 Scan for ZOOM API. New object ZOOM_scanset. New functions
2526 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2527 ZOOM_scanset_destroy.
2529 New ZOOM function, ZOOM_connection_last_event, that returns type
2530 of last event (such as "receive data", "send data", "apdu received",
2533 New ZOOM option, schema, that specifies schema for retrieval.
2535 New CCL feature. Qualifiers can be aliases for one or more
2536 other qualifiers (if more than one is given, OR is used).
2538 ZOOM uses named result sets if target supports it.
2540 Two new YAZ client commands: . (dot, which sources a script of YAZ
2541 client commands), and ! (to execute shell command.). Implemented
2544 Working on Debian packages.
2546 --- 1.8.3 2001/11/19
2548 YAZ client enables named result sets only if target supports it.
2550 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2552 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2553 with key="host" to get same result.
2555 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2556 Function Z3950_resultset_record(s) returns references to records
2557 "owned" by resultset. To become owner use Z3950_record_clone.
2559 Function z_ext_record handles Extended Services. Thanks to
2562 --- 1.8.2 2001/11/12
2564 CCL Parser fix: ignore token comma when dealing with and-lists.
2566 Documentation updates for COMSTACK.
2568 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2569 Changed prototype Z3950_records. For some functions, int parameters
2570 were changed to size_t.
2572 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2575 New MARC decode/display function, marc_display_exl, which properly rejects
2576 non-ISO2709 records. YAZ client uses it.
2578 --- 1.8.1 2001/10/29
2580 Fix bug: local attribute set wasn't set correctly in PQF strings.
2584 * Old Z39.50 codecs no longer supported.
2586 Added ZOOM C binding. See http://zoom.z3950.org/
2588 Renamed states for COMSTACKs to avoid confusion with events.
2590 Implemented cs_look and proper cs_rcvconnect.
2592 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2594 Configure detects POSIX threads on OpenBSD.
2596 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2597 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2599 When error is returned from present handler, non-surrogate diagnostic
2600 is returned in present response (and fetch handler is no longer called).
2602 * Minor adjustments to pquery parser (PQF). Token characters may be
2603 escaped by using backslash (C-style).
2605 PQF parser allows string attribute values to be specified. For @attr,
2606 non-numeric characters after the equal-sign are treated as strings
2607 (e.g. @attr 9=title).
2609 CCL trunction character may be defined (@truncation in file)
2611 * function zget_ExtendedServicesRequest sets waitAction to
2612 waitIfPossible (was wait).
2614 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2617 CCL operator names may be set in field definition files (CCL_bibset).
2618 See ccl/bib1 for an example.
2620 Fixes in ASN.1 compiler for C++ compatibility.
2622 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2623 and "op_or" to avoid conflict with C++.
2625 Fixed problem with GNU readline detection on Redhat 7.0.
2627 Added step-size for Scan backend handler.
2629 Fixed bug that made the frontend server crash when no attribute
2630 set was specified for scan.
2632 Front-end server automatically switches to original working directory
2633 when installed as an NT service. Previously -w had to be specified to
2636 Added extended attributes for retrieval module (data1), so that data1
2637 records carry d1_readXML/SGML attributes. d1_read also supports
2638 null-data rules ( <tag/>)
2640 On UNIX when POSIX threads are available, a separate library libyazthread
2641 is created. Programmers should link with that library and the yaz library
2642 when using threads. The reason for the split was that some applications
2643 on Linux, such as Apache, doesn't work well when using shared objects that
2646 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2647 (or any frontend server) in SSL mode by specifying ssl: followed by
2648 address. Only tested on UNIX.
2650 Added feature for CCL module. Virtual structure s=al or s=ol generates
2651 and-list and or-list respectively instead of phrase search.
2655 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2656 log_mask_str. This was done to avoid name conflicts with other libraries
2657 (such as other PHP extensions).
2659 Added raw OID member for preferred record syntax (request_format_raw)
2660 and returned record syntax (output_format_raw) for backend fetch method.
2662 Config file yaz-config now accepts options so that it returns specific
2663 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2665 Shared library support for UNIX using GNU libtool.
2667 * Modified backend interface. Request/Response struct's replaced by
2668 one read/write C struct. For example bend_fetchrequest and
2669 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2670 Every handler - even search has to be registered in bend_init
2671 handler. This means that the YAZ library no longer refers to
2672 external functions and it makes it possible to make the whole
2673 thing a single DLL/SO.
2675 Added Segment handler for backend server.
2677 Added Zmbol/Zebra administrative functions to YAZ client.
2679 Threaded frontend server on UNIX (when POSIX Threads are available).
2680 Starting the server with option -T enables multi-threading.
2684 Added configure option --enable-comp/disable-comp to control use
2685 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2686 located in sub directory asn.
2688 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2689 in ${exec_prefix}/bin along with the other programs yaz-client and
2692 GNU automake used to maintain makefiles.
2694 Added several OID's.
2696 Changed retrieval module so that we can load records with no abstract
2697 syntax defined. Tagpaths in these records are fully composed of string
2700 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2704 On UNIX, the generated makefile now supports a proper 'make install'.
2705 The prefix can be set via GNU configure to set the install location
2706 (default is /usr/local).
2708 * YAZ programs client and ztest were renamed to yaz-client and
2709 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2710 locations, such as /usr/bin,/usr/local/bin,etc.
2712 * YAZ Header files were moved from include to include/yaz. YAZ Header
2713 files are referred to as include <yaz/log.h> rather than <log.h>.
2714 The YAZ include path (-I ..) is therefore the same as before. Programmers
2715 should update their #include statements or use -Ipath/include/yaz
2716 instead. The main motivation for doing this change is that YAZ header files
2717 can be installed in "standard" locations /usr/include,/usr/local/include
2718 without introducing conflicts, since ALL YAZ header files are stored
2719 in subdirectory yaz (under /usr/include for example).
2721 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2722 rather than project/workspace files. We switched because project files
2723 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2726 Changed name of logging function, logf, to yaz_log, to prevent name
2727 clash with some math-log functions. The YAZ header log.h defines logf
2728 to yaz_log (#define) so there should be no incompatibilities by this
2731 Added bend_start/bend_stop handlers for server. These handler are
2732 called on start/stop of server. For windows they are called whenever
2733 a service is started/stopped.
2735 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2736 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2737 in util/yc.tcl. The auto-generated C code structures are, in a few
2738 cases, incompatible with the old decoders. There are differences in the
2739 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2740 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2741 The preprocessor variable ASN_COMPILED is defined when the compiled
2742 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2743 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2744 wish to use the old encoders/decoders you can specify --disable-yc
2747 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2748 version so that it supports both new - and old version of DB Update
2750 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2751 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2752 change. The name parameter can be set to 0 in which no name is specified
2753 for the construction. The macros odr_implicit and odr_explicit sets name
2754 parameter to zero for the construction involved. New macros
2755 odr_implicit_tag and odr_explicit_tag are similar to the others,
2756 except that a name parameter is added. For programmers' that don't use
2757 ODR they probably only need to change the call to z_APDU and z_External.
2759 Added access control facility by interfacing the TCP wrapper library.
2760 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2761 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2762 name of the daemon and enables the access control as specified in
2763 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2765 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2766 den Dool <H.M.vdnDool@kub.nl>.
2768 Added reference ID parameter to most functions in server API - refer
2769 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2771 Changed name of ccl library to libccl.a (was ccl.a).
2773 Fixed bug in decoder for Explain (Category TargetInfo).
2775 Added support for GNU readline in client. Thanks to Jacob Poulsen
2776 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2778 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2779 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2780 IMPLEMENTATION! This change was made to the development version before
2781 the ZIG decided to retract the amendment. If any users MUST be
2782 compatible with the original Update definition, PLEASE CONTACT US, and
2783 we will include a separate definition corresponding to the old Update
2784 ES. Note that because of the change to the ASN.1 of the
2785 TaskPackageRecordStructure we cannot define a single structure that
2786 will support both versions.
2788 * Added const modifier to buffer parameter for some ODR/BER encoding
2789 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2790 completeWAIS, odr_dumpBER.
2792 Fixed bug in client.c which caused a crash when a scanResponse didn't
2793 contain positionOfTerm.
2795 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2796 * will cause an error in a client if a non-YAZ target sends both a
2797 * list of Scan entries and non-surrogate diagnostics.
2799 Retrieval module enhancements. Tag sets may be typed in the reference
2800 to it. From the .abs-file the "tagset" directive takes a third optional
2801 integer type for the tag set referenced. From a .tag-file the "include"
2802 directive takes a third optional type as well. The old "type" directive
2803 in the tag set itself is still recognized but acts as the default type
2806 Backend interface change. Individual Scan terms returned from bend_scan
2807 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2808 in include/backend.h.
2810 Retrieval module enhancements. Multiple tag sets and attribute sets may
2811 be specified in abstract syntax specs. Revised the error/warning for
2812 logging messages reported by the retrieval module when reading the
2815 Object Identifier system (oid_..) changed. The API is backwards
2816 compatible but the oid-routines now allocates new OID's when needed.
2817 Raw OID's may be specified in oid_getvalbyname.
2819 YAZ now uses GNU configure to generate Makefile(s).
2821 * Minor changes in some of the member names of DeleteResultSetRequest and
2822 DeleteResultSetResponse. See include/proto.h.
2824 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2825 and added member 'languages' in TargetInfo (which was missing).
2827 Changed the way attribute sets are handled in the retrieval
2828 module. These are now cached, just like the abstract syntaxes
2831 Changed YAZ so that it links with compiled ASN.1.
2833 Added Explain-schema definitions and mapping routines. The following
2834 Explain categories have been implemented: AttributeDetails,
2835 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2837 Fixed minor bug in Windows version of Server Library.
2839 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2841 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2843 Added EXTERNAL: UNIverse Resource Report (non-standard).
2845 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2846 ENUMERATED and SET OF.
2848 * Added 'const' to some of the char pointer arguments for the
2849 functions, data1_read_node, data1_getelementbytagname,
2850 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2853 Fixed bug in data1_insert_taggeddata - the last_child member of
2854 parent wasn't initialised.
2856 * Changed data1_read_record and data1_read_node so that the supplied
2857 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2858 doesn't refer to any parts of the "SGML"-buffer.
2860 Fixed bug in server library (Windows version of statserv_remove).
2862 * Changed code so that it compiles as C++. The type definition
2863 of Odr_fun which is a member of Odr_arm was changed. The result is,
2864 that an explicit typecast is needed for the fun pointer when
2865 using Odr_arm - as in:
2866 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2868 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2870 Implemented the new structured date and time definition as approved
2871 by the ZIG. Added schemaId element to the specificTag in Espec-1
2872 (also approved at the last ZIG). Thanks to RVDM.
2874 Added some Object identifiers (RVDM).
2876 Changed the Update Extended Service (RVDM).
2878 Added command "refid" to client which specifies referenceId for
2879 the following requests.
2881 Implemented extended service handling for server. See ztest.c
2882 for an example as well as backend.h. New handlers are registerd
2883 in the Init handler.
2885 * Changed interface for sort in server.
2887 Added new members to statserv_options_block. It allows a server
2888 to read options from another source than just the command line. Thanks
2889 to Charles Woodfield.
2891 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2892 renamed to zboolean. Some C++ compilers complained about the name.
2894 Minor changes to gils.abs. Added index 's' (sort) on title
2895 and date/time-last-modified.
2897 --- 1.4pl2 1998/1/30
2899 Fixed bug in server library regarding inetd mode (-i). This bug
2900 was introduced by release 1.4.
2902 --- 1.4pl1 1998/1/29
2904 Added sort facility in client and backend server interface.
2906 Fixed problem with dependencies in Makefile(s).
2908 Fixed bugs for encoders/decoders of extended services and
2911 Implemented sub-tree feature for schemas. Sub-trees are
2912 referenced in *.abs-files. See explain.abs for an example
2913 of the use of this feature.
2915 Modified bib1.att; local attributes for ANY didn't include
2916 ANY itself (only affects use of the retrieval module).
2918 Fixed bug in plain SGML reader in function data1_read_node:
2919 tags with prefix "var" was incorrectly interpreted as variants.
2921 Added feature "sub-schemas" to enable references to - and definitions
2922 of - group of elements.
2924 * Removed member parent from type data1_element (in data1.h).
2926 Implemented function odr_nullval() that returns the value of
2929 * Removed member num_children from data1_node (in data1.h).
2931 Made NT service interface part of the server library. The
2932 function statserv_main uses the NT service when required and
2933 calls the statserv_start / statserv_close routines.
2935 Routine zget_SearchRequest and zget_PresentRequest fills
2936 resultSetName/Id member with "default" instead of "Default".
2938 Fixed memory leak in server. Request queue member wasn't freed.
2940 Fixed nmem_exit so that memory is freed.
2944 Revised the CCL parser utility to be thread safe.
2946 Added function, oid_ent_to_oid, to replace the function
2947 oid_getoidbyent, which is not thread safe.
2949 * Added nmem_init and nmem_exit to initialize and release
2950 NMEM resources. Function nmem_init should be called once in the
2951 initial thread before NMEM/ODR is used. statserv.c and client.c
2952 have been changed accordingly. The change was necessary to make
2953 NMEM thread safe. The NMEM memory pool is shared amongst threads
2954 in a process. Unix-based applications will still work fine without
2957 Added NT Services interface for the the Z39.50 (statserv) Server.
2958 Refer to the ztest.c source on the usage.
2960 Windows 95/NT port using MSVC5.0. Project files are included in the
2963 * Defined new 'global' handle for the retrieval (data1) system. The
2964 new handled, data1_handle, describes the state of the data1 system.
2965 This handle is passed as first argument to virtually all
2966 data1 related routines. The functions data1_create and data1_destroy
2967 creates and destroys a data1 handle respectively.
2969 Added ODR encode stream member to all backend request structures
2970 init, search, scan etc. This stream should be used to allocate all
2971 memory used for the response when thread safe operation is needed.
2973 Changed the comstack utility, cs_addstr, to be thread safe. The
2974 returned hostname string returned by the function is now part the
2977 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2978 function. The cs_straddr takes a COMSTACK handle as argument, so this
2979 function must be used after cs_create and before bind/connect.
2980 This function is thread safe.
2982 Moved test server to 'ztest' directory - generic server code still
2983 in 'server' directory.
2985 Made prefix query (pquery.c) utility thread safe.
2987 Added new function modifier YAZ_EXPORT to 'export' public DLL
2988 functions when using windows (see include/yconfig.h).
2990 Added definitions to the OID database (util/oid.c) (RVDM).
2992 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2994 Added call to ccl_rpn_delete in client program.
2996 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2997 release of RPN structure.
2999 Added support for C++, headers uses extern "C" for public definitions.
3000 With input from RVDM.
3002 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3003 Thanks to Ronald van der Meer (RVDM).
3005 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3007 Added support for private extensions to the OID database
3008 (oid_setprivateoids()). Thanks to RVDM.
3010 Added optional, physical ANY (key replication)
3012 Fixed null-reference problem in GRS-1 output filter.
3014 Proximity operator added to Prefix Query Format (PQF).
3016 In test client command "base" accepts multiple databases.
3018 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3022 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3024 Smallish bug-fixes in the new encoders/decoders (explain).
3026 Bug fixed in DeleteRequest.
3028 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3030 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3032 Added SOIF syntax (using private OID for now) to retrieval module and client.
3034 Added Update extended service.
3036 Added SearchResult-1 additional info structure.
3038 Added optional CCL (ISO8777) interpreter as separate module. Available
3041 --- 1.2 1996/6/10 (1st anniversary release)
3043 Added Summary record syntax. Lightly tested.
3045 Added OPAC record syntax. Untested.
3047 Added ResourceReport service encoders/decoders. Untested.
3049 Fixed bug in z_Unit - wrong tagging on unitSystem.
3051 Fixed bug in the DiagRecs decoder.
3053 Added options for max PDU size and session timeout to frontend-server.
3055 Added documentation of query-language parsers and other supporting utilities.
3057 [frontend-server] Added Attribute set to the bend_scanrequest API.
3059 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3060 surrogate diagnostics were generated.
3062 [retrieval] Allow multiple local values for attribute.
3064 [retrieval] Allow multiple attributes per element in .abs files. index type.
3066 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3068 --- 1.1pl2 1996/4/10
3070 Minor changes, mostly specific to Zebra's requirements (retrieval)
3074 Repaired bug in frontend server when running multiple listening
3075 endpoints in dynamic mode.
3077 z_External() now won't break if a known, ASN.1 value comes encapsulated
3078 in an octet-string. The value will pass through unmodified in an Odr_oct.
3080 Added a bit of code to the demo client to decode & display
3081 ASN.1-structured records represented in the octet-aligned branch of
3082 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3084 Added z_ext_getentbyref() to the ASN module. Doc updated.
3086 * Completed the SCAN definition in the ASN module. This may break SCAN
3087 code based on older YAZ-versions at compile-time. The fix is easy -
3090 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3091 under the SCAN definition. Remember to initialize this, server-people.
3093 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3094 that this does not extend to ODR and ASN.
3096 Comstack allows insertion of established socket (primarily for
3097 inetd-operation of servers). Doc updated.
3099 Front-end server can now start from the inetd in TCP mode. Doc
3102 --- 1.0pl4 1996/1/24
3106 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3107 the rank and record number.
3109 Adjustments to the frontend server.
3111 Fixed diagnostic BER dumper. It ignored the file argument.
3115 Various changes to retrieval module.
3117 Changed the union discriminators of the protocol files from enums to
3118 ints paired with #defines.
3120 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3123 *Changed operator in the RPN structure to 'roperator', again to avoid a
3126 Fixed problems in Explain decoders/encoders.
3128 --- 1.0pl2 1995/12/6
3130 Memory bug in log module fixed.
3132 --- 1.0pl1 1995/12/5
3134 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3136 Bug in Explain DatabaseInfo module fixed.
3138 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3142 The shift to v1.0 signals that we now consider the *core* functionality
3143 of YAZ reasonably stable (the core being more or less equivalent to
3144 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3145 tested (Explain not at all - though that will happen soonish).
3147 Minor changes to code to support Windows port.
3149 Various minor changes after we're getting to use GRS-1 & co. more.
3151 Added Espec-1 format.
3153 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3154 of the protocol and it cannot be selected when encoding (maps into 'string'
3155 when decoding). Needed to talk to some servers.
3157 Demo client can request simple element set names.
3159 Added Diagnostic Format encoders/decoders.
3161 Added simple Close handling to frontend server (no hooks for resource
3162 reporting yet), and demonstration client.
3164 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3166 --- 1.0b3 1995/08/24
3168 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3169 handled incorrectly when records were requested in the searchResponse. This
3170 will only affect you if you use the frontend-server.
3172 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3173 Test-client will ask for and print GRS1. Ztest will return dummy records
3176 Added Explain encoders/decoders to the service-level API. Untested.
3178 Added Extended Services: Item Order encoders and decoders to the Service-
3179 level API. Untested. We could use a recent copy of the pertinent bits
3180 of the ILL protocol to add those bits.
3182 Added diagnostic format 1 encoders/decoders to the service-level API.
3185 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3186 odr_cons.c, which causes a more correct output.
3188 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3189 was always set to 0 when no records were requested in the searchRequest.
3191 * Added better external-handling. This shouldn't harm old code that
3192 *encodes* externals. It can break code that looks for a
3193 'single-ASN1-type' representation, since those types that are known
3194 are now decoded immediately. Look at the SUTRS sample code in
3195 seshigh.c and client.c. Documentation updated.
3197 Handling of structured records in bend_fetchresponse. Length -1 marks
3198 structured record, type is deduced from format field.
3200 --- 1.0b2 1995/06/27
3201 Fairly quick maintenance release to add SUTRS support.
3203 Fixed handling of SUTRS records in the demonstration client.
3205 * Added format field to the bend_fetchrequest and bend_fetchresponce
3206 structures of the backend API (frontend server). When the record is
3207 returned, the value of the format field is mapped to an OID. The
3208 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3209 of the record. The special value VAL_NONE in the bend_request means
3210 that no specific format was requested by the client. Documentation
3211 updated accordingly. Test server (ztest) will return a fixed dummy
3212 SUTRS record if your client requests SUTRS.
3214 Documentation updated accordingly.
3216 You can now set external libraries and RANLIB support in the top-level
3220 First public release.
