1 zoom/record_render: add support for Base64 decoding fo MARC records
2 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
3 which will decode base64 + ISO2709 marc-8 encoded material from text node
8 Add missing definitions ZOOM_resultset_get_facet_field_by_index
9 and ZOOM_resultset_facets_names.
11 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
14 Change APDU dump printing to avoid long leading blanks. For levels 16
15 or larger the level is shown and the indentation is truncated but
16 recursed with modula 8. This makes it still reasonable easy to read
17 - even for nested BER dumps.
19 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
20 return 0 (incomplete package) in case where the BER package was
21 considered too nested (return value of -2).
23 dumpber: lines of level 15 are not indented further. Two spaces per
24 indentation; indentation 15 or more is indented to a fixed indentation
25 and augmented with a level=<no> indication.
27 zoomsh: increase max size of command+args
29 GFS: No limit in RPN buf size in CQL to RPN conversion.
33 New function for daemon utility, yaz_daemon_stop .
35 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
39 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
40 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
44 YAZ daemon utility relays SIGUSR1 to child process.
46 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
47 would result in en empty database list - which in turn would result in
48 encoding failure for search.
50 Fix reading beyond string in yaz_sort_spec.
54 Add two new SRU diagnostics:
55 236: Access to specified database denied
56 1015: Init/AC: Maximum number of simultaneous sessions for Userid
58 Document the very useful ZOOM-C option "apdulog".
60 CQL to RPN: term may be passed through verbatim. This is enabled with
61 truncation.cql . The assumption being that the term is already CQL.
65 record_conv: leader spec may be given for marc element.
66 The leader spec is given as attribute leaderspec for element marc.
67 For example to convert a MARC21 record from MARC-8 to UTF-8:
68 <marc inputformat="marc" outputformat="marc"
69 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
71 record_conv: allow user-XSLT params. For example:
72 <xslt stylesheet="MARC21slim2DC.xsl">
73 <param name="myparameter" value="myvalue"/>
74 <param name="otherparameter" value="othervalue"/>
77 record_conv: fix error handling for missing marc charsets.
79 CQL: fix extra terms in wrong order.
83 record_conv: modify new API for conversion types. The conversion types
84 may be passed in new functions yaz_record_conv_configure_t and
85 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
87 Avoid mixed statement/variable declare; fixes compilation with Visual
92 Add non-standard SRU diagnostic: 235: "Database does not exist".
93 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
94 Update SRU to Bib-1 diagnostic maps accordingly.
96 CCL: add two new diagnostics for unsupported masking. The new
97 diagnostics are: "Embedded truncation not supported" and
98 "Single charcacter mask not supported".
100 --- 4.2.26 2012/02/23
102 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
104 --- 4.2.25 2012/01/11
106 Build YAZ for Ubuntu Oneiric.
108 CCL: allow parantheses for proximity operands. For example CCL query
109 (a) % (b) is now allowed.
111 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
112 marked dead, rather then being destroyed. If not, the session memory is
113 being free'd before the search/scan handler is finished. Also destroy
114 'request' memory in request_release rather than in various places,
115 which resulted in leaks from time to time.
117 --- 4.2.24 2011/12/21
119 cql_sortby_to_sortkeys: honor sort prefix.
121 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
122 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
123 The rpn2cql family of functions now always returns quoted CQL terms.
125 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
127 --- 4.2.23 2011/12/15
129 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
130 sequence is treated as one. For example, &&a=b&&&c& is identical to
133 --- 4.2.22 2011/12/05
135 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
136 APDUs for a connection to a WRBUF.
138 --- 4.2.21 2011/11/23
140 Fix cql_sortby_to_sortkeys. Completely broken before.
142 Make CCL's @truncation work again.
144 --- 4.2.20 2011/11/09
146 New ZOOM connection setting: tproxy. It's like proxy, but does not
147 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
148 to set resolved address + port for a connection outside ZOOM itself.
150 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
152 --- 4.2.19 2011/11/07
154 Fix uninitialized variable in Solr spell support (could cause SEGV
155 for SRU response decoding).
157 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
158 back-end's addinfo through into the ZOOM response addinfo.
160 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
161 they are separated by a colon and a space rather than simply
164 --- 4.2.18 2011/10/28
166 Add support for Solr spell-checking/suggestions through ZOOM.
167 If a Solr target has been configured correctly for spelling-checking
168 and suggestions, these will now be returned on the ResultSet option
169 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
171 --- 4.2.17 2011/09/28
173 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
174 with a flag whether to substitute escape sequences or not.
176 --- 4.2.16 2011/09/22
178 Fix nmem_strsplit_escape to substitute escape char properly.
180 New option for zoomsh -e , which makes it abort on first error and
181 return process exit code to indicate success/failure.
183 YAZ options utility supports special option -- which makes all it treat
184 all following arguments as non-options.
186 --- 4.2.15 2011/09/16
188 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
189 searched if absolute filename is given.
191 Fix conv_xslt() error-reporting when stylesheet is not found.
192 (The value of fullpath is meaningless in this situation.)
194 --- 4.2.14 2011/09/07
196 Fix problem in CQL sort node creation: un-initialized memory.
198 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
199 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
200 CQL sortby depending on whether Type-1 or CQL is actually sent to the
203 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
204 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
206 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
207 will make it possible to use both single-character mask (#) and wildcard (?)
208 in CCL . Throw diagnostic for left truncation because that is not supported
211 --- 4.2.13 2011/09/01
213 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
214 cases using escapes (\-sequences) and masking.
216 PQF parse fix: A trailing backslash followed by end-of-string (\0)
217 would result in a read one byte beyond string.
219 rpn2ccl may use Z39.50 masking for terms (t=z).
221 ICU check fix. Don't include library -lCrun on Solaris, unless present.
223 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
224 not --cppflags (which seeems like an error in icu-config).
226 --- 4.2.12 2011/08/27 RPM package only
228 cql2ccl: fix conversion of terms: operator characters were not
231 --- 4.2.11 2011/08/25 RPM package only
233 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
234 CCL parser will map both # and ? to their regular expression
235 quivalents (. and .*).
237 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
238 of reserved CQL characters.
240 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
241 is, so that they are passed through.
243 --- 4.2.10 2011/08/24
245 ZOOM SRU mode: more aggressive re-connect.
247 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
248 made available as a utility function, declared in <yaz/logrpn.h>
250 rpn2cql_structure() supports proximity nodes (except that the Type-1
251 proximity node's "exclusion" binary is ignored, as there is no way to
252 express that in CQL). Fixes bug #4564.
256 Fix SEGV that could occur if set command of zoomsh was given without
257 value (2nd argument).
259 Fix SEGV that could occur if unsupported transport was given for
260 COMSTACK - say https (when SSL was unavailable).
262 Build yaz-url on Windows too.
266 New utility to get web content. Header is url.h. A command line tool
267 yaz-url is part of the distribution and packages.
269 Fixes for SSL COMSTACK (when gnutls is in use).
271 New functions yaz_base64{encode,decode}. Header is base64.h.
275 ZOOM C includes HTTP response buffer as additional info if it fails
276 to decode the SRU response.
278 Make wrbuf_json_puts available.
282 zoom: throw diagnostic for invalid value for option "sru". Before a
283 bad SRU request was sent.
285 Adding new utility wrbuf_vp_puts.
287 Add cclxmlconfig.obj to win/makefile. It was missing completely.
291 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
292 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
293 redirect was used at the same time.
295 MARC line mode decoding: be less picky about length given - first
296 5 digits of header that is.
298 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
300 Changes to decoding of SRU records: a record with recordPacking=xml is
301 modified with a new root element <yaz_record> if the recordData contains
302 multiple children elements. This is to make the record XML parseable
305 RPN to SOLR conversion: encode special characters.
307 Generic Frontend Server: fix uinitialized member, stepSize.
311 Fix a bug in SRU decoding of records.. The database records stored
312 had un-initialized memory, but it would only be seen with yaz_record_render
313 and type_spec="ext" .
315 Fix a bug in ccl_qual_dup introduced in 4.2.3.
319 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
323 Add new utilities to convert from CQL to CCL . These utilities have
324 prefix cql_to_ccl defined in cql.h.
326 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
327 lead to memory heap corruptions when ICU utilities were in use.
331 Make compilation work without Libxml2.
333 yaz-client: remove redundant blanks in display of searchResult-1 term
338 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
339 resulting CQL node (tree) in a new node CQL_NODE_SORT.
341 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
342 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
343 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
344 Note that the CQL sortby spec is only converted when the GFS is already
345 converting from CQL to RPN (cql2rpn element).
347 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
348 specify whether to collapse delimitors or not. The existing nmem_strsplit
349 do collapse (collapse parameter = 1).
351 Windows installer: For NSIS, set InstallDir depending on x86/x64.
353 Rename internal func yaz_use_attribute_create. While non-static, this
354 function is not declared in a public header.
358 Add -lCrun when linking with ICU on Solaris.
360 More quicks character set conversions for OPAC records.
364 fix problem with record_render: records were converted (character set
365 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
369 SRU: add methods for handling DADS SRU-proxy facets.
371 Separate OPAC record character set for ZOOM_record. yaz_record_render
372 allows a character set given as charset=from/opacfrom,to where 'from' is
373 the character set of a bibliographic record, 'opacfrom' is character set
374 of OPAC record and 'to' is the target character set.
378 yaz-client: show may XML format records. Command show followed by 'format'
379 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
382 src/stemmer.c: Avoid using unnamed union. It is not supported by some
385 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
388 Update yaz.spec to operate on both SLES11 / Centos 5.5.
390 RPM: Release includes 'indexdata' name. Use indexdata in release name so
391 this package can be distinguished from other vendors.
393 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
394 as determined by configure
396 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
398 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
399 returns no error and no record, the present request is considered
400 partial (only a subset of the records could be returned by backend), and
401 so it is appropriate to set Present Status to partial-4.
405 Move yaz-config man pages to section 1.
407 More documentation about SOLR.
409 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
410 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
411 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
412 peers on some Linux systems. However, in general that does not work
413 so YAZ can not rely on that to work. Debian changed behavior in this
414 respect from Debian lenny to Debian squeeze (still testing as of Oct
416 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
418 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
422 Fix yaz-config output: echo_source not set correctly by configure.
426 SOLR WebService support for yaz-client and ZOOM.
428 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
430 --- 4.0.12 2010/08/17
432 Z39.50 facet support. Facet specifications are passed for search in
433 other-information with ASN.1 as defined in facet.asn and OID
434 .10.1000.81.5 . Facets are expressed as an Attribute list as known
435 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
436 3 is limit (number of entries to get in response). yaz-ztest returns
437 dummy facets if a client asks for them.
439 --- 4.0.11 2010/07/09
441 CCL fixes: bug 2895 and bug 3539.
443 GR1-display: add comma in display - was removed by mistake in
446 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
448 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
450 --- 4.0.10 2010/06/18
452 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
453 result set from a connection. The result set will be on its own
454 thereafter; no operations on it will perform retrievals from a target.
455 Only cached copies are returned.
457 ZOOM C:fix case for HTTP servers responding with Connection:close.
458 Ensure that if there is a current task it is resumed (like fetching
459 more records in a result set) . Bug #3484.
461 PQF parser: use odr_atoi for Odr_int (not atoi)
463 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
464 values that contain any non-digits are treated as string attributes
465 (previously decoding only checked for leading character ([0-9]). PQF
466 encoding: attribute string values are not surrounded by double-quotes.
470 New utility for managing threads - thread_create.h.
472 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
473 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
474 but YAZ' implementation do.
476 Fixes for yaz_cond-functions on Windows 7.
478 DLL export more symbols.
480 zoomsh: show record do NOT render opac.
482 Remove *.la files from Debian and RPM packages.
486 Debian package libyaz-dev depends on libgnutls-dev again (was
487 removed in YAZ 4.0.6, but due to Libtool it is still needed
488 even though yaz-config do not list libgnutls libs).
490 ZOOM: Use only one WRBUF for returning string results for
491 ZOOM_resultset. Reduces memory usage for ZOOM in general.
493 ZOOM: ZOOM_connection do not use a shared pointer to
494 ZOOM_resultset after ZOOM_resultset is destructed by
495 user. Reverts to YAZ 4.0.4 behavior.
499 record-conv: fix problem with at least one XSL conversion -
500 due to probably incorrect usage of XML XSL documents.
504 Fix yaz-config for static mode and the use of SSL (gnutls).
508 Forward decl timeval struct in mutex.h and gettimeofday.h.
510 yaz-config: fix 'static' mode linking.
514 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
515 are wrappers for pthreads or Windows. For Windows these are put in
516 a separate DLL: yaz_cond4.
518 libyaz.la (whole source) is compiled with thread. If thread support
519 is enabled enabled, all source of YAZ is compiled with treading support.
520 This allows core utilities such as yaz_log to use thread facilities.
521 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
522 thread utilities. This commit moves mutex utilities (mutex.c) from
523 libyaz_server.la to libyaz.la.
525 yaz-json-parse displays leading text until error.
529 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
530 patch from Giannis Kosmas.
532 SRU: no longer URL encode SRU database. The URL for an SRU server is
533 a URL and such is alreeady encoded - at least when given with leading
534 http:// or https://. This reverts behavior to YAZ 3.0.50.
536 Support for new MARC XML notation TurboMARC which like MARCXML is a
537 complete representation of MARC/ISO2709.. This one, however, is more
538 compact and allows for faster processing with XSLT. TurboMARC can be
539 used in the marcdisp.h API, from the yaz-marcdump utility and from
542 yaz-ztest can be configured - via the database - to perform certain
543 delays when it performs operations search, present and single record
544 fetch. This allows testers to make yaz-ztest act as a real or even slow
545 Z39.50 server. Refer to the yaz-ztest man pages for details.
549 wrbuf_destroy allows NULL WRBUF passed to it.
551 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
553 Add ZOOM_connection_close.
555 No fixed size buffers for ZOOM shell - bug #3257.
557 tstodr: make it work on s390 platform.
559 New icu iterator-functions. The new icu_iter-functions makes it possible
560 to use ICU chains from many threads.
562 yaz-client: better syntax check for show command.
566 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
569 New simple local-file XML include facility which allows file glob-patterns.
570 Refer to yaz/xml_include.h.
572 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
575 ZOOM_record_get supports new parameter "format" which makes it format XML
578 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
579 JSONText in ECMA-262) is JSONValue, not JSONObject.
583 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
584 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
586 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
587 POSIX/Unix builds .so with major version 4.
589 Remove old LOG_-defines from log.h. They have been obsolete and
590 undefined by default for the last 5 years.
592 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
594 GFS: Remove socket (int *fd) from search_rr handler. The socket
595 descriptor ptr is a facility that allowed a search handler to supply
596 a socket which would serve as a callback - when search was complete.
597 This facility has now been in use for years.
599 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
600 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
601 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
602 returns 'const char *' rather than 'char *. The returned string is
603 read-only and should not be modified by applications. COMSTACK cs_close is
604 now a void function - it no longer returns int. No applications check for
605 the value and the implementations has always returned 0.
607 ZOOM: use size_t for scan hit counts and str size. Functions
608 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
609 occ (hit count) and len (string length) are now of type size_t pointer
610 rather than int pointer. This is to be able to represent large hit counts
611 and to also just to use the proper type for string length (strlen result).
613 New JSON parser. Refer to include/yaz/json.h .
615 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
616 Used to be int in some cases. Many wrbuf_-functions used to return an int
617 indicating some length.. These return values were never used. And so they
620 ODR: odr_malloc, odr_total now takes size_t for size.
622 clone_z_type: fix leak; occurred for encoding failures.
624 --- 3.0.52 2009/12/03
626 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
627 bug was introduced in 3.0.51.
629 --- 3.0.51 2009/12/02
631 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
633 tcpip comstack: fix leak for getaddrinfo.
635 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
636 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
637 Decoding of SRU "path" database is performed by private function
638 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
639 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
641 yaz-client: honor base command for SRU. Change when database setting
642 is applied for SRU and ensure it is kept when a connection is reset.
643 Change also the way errors are displayed or SRU (decoding of packages).
645 --- 3.0.50 2009/11/02
647 Add support for extra request / response data for SRU codecs and GFS.
648 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
649 for extra data response buffer and length. For the GFS, both request
650 and response data (XML) is carried in extra_args and extra_response_data
651 for the search handler. Patch by Ko van der Sloot.
653 ZOOM: For queries that cannot be converted to the specified rpnCharset,
654 ZOOM now returns a diagnostic on the client-side ('invalid query' /
655 10010). This fixes bug #2113.
657 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
658 cmdfile included a 'quit' command that would result in a memory violation.
660 --- 3.0.49 2009/10/01
662 Make a number of functions defined in xmlquery.c static. These have
663 never been declared in a public header file (yaz/xmlquery.h) and was
664 made public by mistake.
666 Improve speed of character conversions (iconv utilities). This makes
667 conversions from MARC-8 faster.
669 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
670 unless type desired is "raw". This will prevent type "xml" from
671 returning ISO2709 .. Which obviously can not be XML parsed.
673 Fix memory leak in ZOOM that would occur if option apdulog was used
674 on a re-used connection.
676 Frontend server logs HTTP requests.
678 Frontend server now sends Z39.50 close when it times out (sesssion has
679 been idle for too long). Versions 2.0.30 and earlier also sent close.
680 But due to a mistake this was disabled in all versions after that, i.e.
681 the server would just close the socket immediately.
683 yaz-client emits a better message when receiving an unrecognised
684 userInformationField.
686 Skip zero-length subfields when decoding ISO2709. This rare case happens
687 if a record has two FS characters in a sequence. Without this patch
688 there would be a reference beyond char array in using_code_len fragments
691 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
693 --- 3.0.48 2009/08/28
695 The show command offered by the zoomsh command now takes a 3d optional
696 parameter type which is what is passed to ZOOM_record. If the type
697 argument is omitted, "render" is used.
699 RPN to CQL conv may use USE string attributes (bug #2978).
701 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
703 --- 3.0.47 2009/07/08
705 Function yaz_xml2query allows a diagnostic element in the PQF XML
706 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
707 code and additional info respectively.
709 The BER BOOLEAN is now the integral type Odr_bool which still happens
710 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
711 typedef'd to Odr_int. This is still an integral 'int', but it may be
712 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
713 ASN-1 compiler as well as programs has been updated to use the new types.
715 --- 3.0.46 2009/06/08
717 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
718 only the bibliographic record was rendered. For type=opac, an OPAC
719 record is only returned if it is present.
721 iconv: small fix for encoding of advancegreek.
723 yaz-client: avoid double display of SRU/SRW records (bug #2798).
725 yaz-client: option auto_reconnect=on really reconnects.
727 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
729 server: avoid null ptr ref for for yaz_poll errors.
731 build: fix RPM build for RHEL 5.3.
733 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
735 --- 3.0.45 2009/03/31
737 Fixed bug #2709: TCP connect returns Invalid argument.
739 Fixed compilation for mingw.
741 Honor charset for raw records (ZOOM_record_get).
743 Fixed use of errno for threaded mode that was seen on Solaris 10.
745 Fixed argument passing with blanks in value for Windows Service.
747 Disable YAZ' own log rotate by default (no 1 GB limit).
748 The variable l_max_size which specifies the log file limit is set to 0
749 (DISABLED): This is due to the fact that YAZ is most often deployed using
750 logrotate. Also YAZ can not perform log rotate because of unsufficient
751 permissions (setuid).
753 --- 3.0.44 2009/02/17
755 List supported encodings in man page for yaz-iconv.
757 Fixed missing SSL libs for --libs output
759 Re-established OID record syntax application-xml. Nobody should use it
760 but we don't want to change soname because of this symbol being absent.
762 --- 3.0.42 2009/02/02
764 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
766 Added member named_result_sets for init handler struct for the GFS. This
767 allows a server to disable named result sets.
769 Removed OID record syntax application-xml.
771 Added support for rule-based transliterator for ICU wrapper of YAZ.
773 Fixed bug #1902: yaz-icu XML output.
775 Make YAZ checks Emacs friendly.
777 BITSTRING value shows value. Bug #2346.
779 ISO2709 decoding: skip control characters from indicator data.
781 Omit sort key by default in yaz-icu's output.
783 Allow combined single char options (again) for YAZ' options function.
785 Utility yaz-marcdump got option to display YAZ version (-V).
787 Allow YAZ to use ICU 3.4.
789 Added new ICU test case which illustrates removal of diacritics.
791 --- 3.0.41 2008/12/29
793 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
795 --- 3.0.40 2008/12/29
797 For configure, using option --without-xml2 also disables Libxslt/Libexslt
800 Fixed bug #2352: yaz-marcdump crashes for certain record.
802 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
804 Added support for Danmarc2 to UTF-8 conversion.
806 Added support for ISO5426 to UTF-8 conversion.
808 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
809 implementation version.
811 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
813 --- 3.0.38 2008/11/10
815 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
816 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
818 ZOOM C now interprets databaseName option for ZOOM connection as path
821 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
823 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
825 Dummy Libxml2 types no longer defined in headers of YAZ'.
827 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
830 --- 3.0.36 2008/09/26
832 Various ODR chapter fixes.
834 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
836 Added missing source for Windows compilation, mutex.c.
838 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
840 For SRU connections in ZOOM all records up to "count" are now fetched.
842 Fixed crash in generic frontend server (and yaz-ztest) which occurred
843 in Windows due to bad error handling for Libxml2.
845 Added facility for sending arbitrary records (ASN.1 any) using
846 ZOOM C's Extended service update. Patch by Sam Reynolds.
848 New options for ZOOM C's connection, logapdu which makes ZOOM log
851 --- 3.0.34 2008/06/18
853 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
855 --- 3.0.32 2008/06/12
857 Fixed memory violation that could occur when decoding UTF-8. This bug
858 was only present in 3.0.30 of YAZ.
860 --- 3.0.30 2008/06/06
862 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
863 GNU TLS is used by default (if found).
865 yaz-ztest returns OPAC records if a client asks for OPAC.
867 Improved speed of MARC-8 encoding.
869 Added support for lossy and loss-less MARC-8 encoding.
871 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
873 Added new Windows Service wrapper (sc).
875 yaz-client's itemorder command may now send a file.
877 Fixed yaz-marcdump to allow the use of NS prefix for record element.
879 Added new function yaz_log_xml_errors.
881 Allow (but warn) unknown XML attributes in MARCXML parsing.
883 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
885 The UTF-8 to MARC-8 conversion now uses a different set of characters
886 for Greek symbols. Bug #2120.
888 --- 3.0.26 2008/02/21
890 Added yaz_daemon (daemon.h).
892 Fixed bug #2068: pkg-config trouble
894 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
896 --- 3.0.24 2008/01/28
898 Document --with-xml2 option.
900 Added OPAC XML XSD (etc/opacxml.xsd).
902 Allow glob mask for name attribute in retrieval element for the
903 generic frontend server's retrieval facility.
905 Changed yaz_poll_poll to return yaz_poll_except for all returned events
906 except POLLIN/POLLOUT.
908 Fixed error handling in cs_listen. Bug #2037.
910 --- 3.0.22 2008/01/20
912 Fixed version in yaz/yaz-version.h.
914 Fixed bug #2027: Crash when closing connection.
916 Changed configure so that ICU support is only enabled if only ICU
917 and Libxml2 is available (because the ICU chain is XML based).
919 --- 3.0.20 2008/01/15
921 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
922 is built. Only this DLL depends on the ICU runtime.
924 yaz-ziffy is no longer part of YAZ. It is distributed separately by
925 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
927 Changed license of CCL module to 'Revised BSD'. After consultation with
928 remaining members of the original EUROPAGATE consortium, we are re-issuing
929 the CCL module without a separate license. The software was developed by
930 Index Data as part of a research project. The special license was included
931 to help feed usage information back to the project consortium to support
932 project evaluation. At this time, the project consortium has long-since
933 disbanded, and the majority of the original principals have retired. At the
934 same time, we have significantly modified the software during the following
935 years, to the point where very practically no original code remains. To
936 simplify re-use of the software, we have contacted those members of the
937 consortium who could be reached, and agreed to re-issue the module as a
938 proper part of the YAZ package.
940 Tcl scripts uses /usr/bin/tclsh as preferred shell.
942 CQL closer to being version 1.2 compliant. CQL also allows free-form
943 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
946 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
947 bug could make Extended services handling crash in the ZOOM layer. This
948 bug was only present in YAZ 3.0.18.
950 --- 3.0.18 2007/12/19
952 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
955 yaz-marcdump reads and writes collection wrapped records.
957 Handle OPAC for record conversion module.
959 Fixes for ICU wrapper.
961 Allow ICU libs to be controlled with --with-icu .
963 --- 3.0.16 2007/11/12
965 Added yaz_poll which is a wrapper for select/poll. When poll is available
966 and non-buggy, it is used, by yaz_poll . This allows more than 1024
967 sockets to be in use.
969 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
970 functionality through an XML based configuration (ICU chain). This system
971 is useful for search facilities such as Pazpar2 and Zebra that needs to
972 perform tokenization of indexed material. The ICU code in a separate
973 library libyaz3_icu.a.
975 Added HTTP tunnel facility for COMSTACK, bug #1752.
976 This is a facility that allows a Web proxy, such as squid, to tunnel
977 Z39.50 traffic. This facility is "transparent" to must applications
978 using YAZ. It's enabled by using pseudo transport connect: followed by
979 the proxy address, followed by command, then follwed by he regular
980 "virtual" addresss. For example,
981 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
983 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
985 --- 3.0.14 2007/09/21
987 Fixed bad memory reference in ZOOM_record - cuased by member not being
988 initialized. This was a problem only in YAZ 3.0.12.
990 Fixed bug in conversion from MARC to XML: Non-XML characters in control
991 fields were not removed.
993 Changed the way C code is generated from codetables.xml. Made a MARC-8
994 conversion trie for each characterSet section rather than codeTable.
995 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
996 of codetables.xml from Larry Dixson, LOC. Bug #1464.
998 --- 3.0.12 2007/09/12
1000 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1001 from ZOOM_record_error).
1003 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1005 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1007 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1009 Better SRW-to-Bib-1 diagnostic mapping.
1011 ZOOM C and yaz-client announces SRU version 1.2 by default.
1013 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1016 Fixed in yaz_sru_decode to allow other version than 1.1.
1018 --- 3.0.10 2007/08/22
1020 Added support for SRU scan for ZOOM.
1022 Added support for the use of the older versions or Extended Service
1023 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1024 set to the version , 1=first, 2=second, 3=third. The third version is
1025 what ZOOM C has used so far. And that, obviously, is the default.
1027 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1028 therefore in Zebra and in SimpleServer-based applications). The new
1029 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1030 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1031 which is passed into the back-end search callback function.
1033 Added support for HTTP Basic authentication in clients: the SRU/W
1034 codec encodes the username/password elements of the PDU structure
1035 appropriately, and these may be set using the "user" and "password"
1036 options in ZOOM-C applications (the same options that are used for
1037 Z39.50 authentication).
1039 --- 3.0.8 2007/06/25
1041 Fixed bug #1208: SSL appears to be broken in ZOOM.
1043 Fixed bug #1206: Libxml2 include path weirdness.
1045 Added oid_name_to_dotstring.
1047 Allow elementSetName to be specified for ZOOM C record update.
1049 Allow waitAction to be specified for ZOOM C based for Extended Services.
1051 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1052 syntax OID. Bug introduced in YAZ 3 series.
1054 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1056 --- 3.0.6 2007/06/06
1058 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1059 directory. yaz-client now reads commands from file given by option -f
1060 if specified; then tries to read .yazclientrc in current directory.
1061 Failing that, it reads .yazclientrc from user's home directory.
1063 Added support for correlationInfo Note and ID for Record Update via
1066 Added yaz-client command querycharset which specifies character set for
1067 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1068 (termListAndStartPoint).
1070 Charset ISO5428:1984 is an alias for ISO5428-1984.
1072 Implemented a way to perform scan in a result set using Z39.50. This
1073 is achieved by attaching the result set name in the characterInfo
1074 (type InternationalString) of OtherInformation in the Scan Request PDU.
1075 The result set is identified in the otherinformation by the new OID:
1076 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1077 This allows for scan in result set and faceted search . Zebra did some
1078 of this in the APT term using attribute type 8 and value being result
1079 set. Using the OtherInformation approach for this is cleaner and easier
1080 to work with in proxies and the like. This facility can be used in
1081 yaz-client using new command setscan which takes a result set as first
1082 argument, start position (APT) as second.
1084 Changed decoding of SRU XML packed records to deal with servers that
1085 have recordData with XML data with multiple root nodes. Also make
1086 comparison for recordPacking case insensitive. Again, one server
1087 returns "XML" where others return "xml".
1089 For SRU responses allow Content-Type application/xml as well as text/xml.
1091 --- 3.0.4 2007/05/21
1093 Fixed bug in character set conversion of BER strings. Bug introduced
1096 --- 3.0.2 2007/05/08
1098 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1100 For OID class, use oid_class consistently.
1102 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1105 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1106 character set for bibliographic information interchange". By Giannis Kosmas.
1108 Added documentation on new OID API.
1110 --- 3.0.0 2007/05/02
1112 Changes to generic frontend server interface: added new member
1113 'query_charset' for bend_initrequest structure. A backend init handler
1114 should set this member to its native character set for query terms.
1115 When defined, the frontend server logic will announce this character set
1116 to a client if the negotiationModel bit is set by the client. All server
1117 implementors are encouraged to specify this. If a backend server does not
1118 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1120 Added CCL utility to remove terms (stop words) from resulting RPN
1121 tree. This is handled by functions with prefix ccl_stop_words_ .
1123 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1124 terms in RPN queries.
1126 Clean-up the CCL API. Moved some internal structures from ccl.h to
1127 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1128 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1129 This is replaced by ccl_parser_find_str which takes a string instead.
1131 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1132 libyaz.la is the core of YAZ except the generic frontend server and
1133 does not depend on POSIX threads anymore. libyaz_server.la is the
1134 generic frontend server facilities and uses POSIX thread functionality
1135 if available. The libyaz.la no longer depends on POSIX threads because
1136 the number of global structures is limited. NMEM no longer re-uses blocks
1137 between threads ; it simply free's memory immediately but allocates in
1138 "large" chunks as usual. We don't expect any performance penalties
1139 because of this. The yaz_log system is still using a global log_level so
1140 caution must be taken when modifying it with yaz_log_init_.. +
1141 yaz_log_mask_str. This, however, should not cause any trouble because
1142 these functions are called during initialization of application code
1143 anyway. `yaz-config --libs server` returns libs for server applications;
1144 `yaz-config --libs` returns libs for non-server applications.
1146 New OID database - with public definitions in oid_db.h. Removed old OID
1147 database including the head oid.h and definitions such as enum oid_value
1148 and struct oident. The new OID database uses the same string names as
1149 before but the 'protocol' is gone. There are now only two representations
1150 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1151 converts from string to OID; functions with prefix yaz_oid_to_string
1152 converts the other way.
1154 Change to emit_term() in CQL-to-PQF query translation: when a term has
1155 the /regexp relation modifier, do not process it for leading and
1156 trailing "^" and "*", which have quite different meanings in regular
1159 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1160 write handlers no longer carries a 'last' parameter. This will make
1161 yaz_iconv flush "less" characters. A flush is performed by call to
1162 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1164 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1165 removed, because function yaz_query_to_wrbuf does the same.
1167 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1168 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1170 Deprecated MARC utility functions removed.
1172 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1175 Branch split: YAZ_2_1_55_branch
1177 --- 2.1.54 2007/03/16
1179 Fix to ZOOM-C so that transparent reconnection is properly handled on
1180 connections that are in asynchronous mode.
1182 Fixed compilation on OpenBSD 4.0.
1184 Large strings in GRS-1 records are now properly displayed in yaz-client.
1186 Added character conversion support for "advancegreek"; based on patch from
1189 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1190 sequence is met. Before the error was not set so it would be unknown.
1192 Adjust yaz-marcdump MARC reader so that it skips until record separator
1195 --- 2.1.52 2007/03/07
1197 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1198 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1199 fd_set structure used as a bitmask for the FDs to be selected on.
1201 Using ACX_PTHREAD macro to check for POSIX threads.
1203 Fixed have-vsnprintf check.
1205 --- 2.1.50 2007/02/23
1207 Fixes for configure on BSD. Bug #900.
1209 Added snprintf/vsnprintf wrappers for systems that don't have
1210 limits (heavens forbid).
1212 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1213 created before all previous tasks were completed and removed from the
1214 task queue, the new task could be removed by a mistake.
1216 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1218 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1220 Fixed bug #832: Problem with MARC/charset in yaz-client.
1222 Fixed bug #668: save command line history for yaz-client.
1224 Fixed bug #830: pkg-config support.
1226 --- 2.1.48 2007/01/23
1228 Extended ZOOM result set options with two options that may be read by
1229 a client: resultSetStatus and presentStatus with values as specified for
1231 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1233 Fixed bug #827: Using SSL fails on Debian etch.
1235 Fixed bug #826: Weird looking chars for set of MARC records.
1237 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1238 that is treated as an ItemOrder with itemRequest being an XML document
1239 external. The value of "doc" is the content.
1241 Extended the GFS search facility. New member of bend_search_rr
1242 'estimated_hit_count' signals that hits is known to be an estmate
1243 (higher or lower than real hit count). New member 'partial_resultset'
1244 signals that the search was partial (hit count is lower or equal than
1245 real hit count). For Z39.50, the information is stored in resultSetStatus
1246 member of SearchResponse APDU. For SRU, the information is signalled
1247 via SRU diagnostic 59: "Result set created with valid partial results
1250 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1252 --- 2.1.46 2007/01/13
1254 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1256 Added ZOOM_connection_peek_event.
1258 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1259 the following new functions:
1260 ZOOM_event_nonblock, ZOOM_connection_process,
1261 ZOOM_connection_get_{socket,mask,timeout},
1262 ZOOM_connection_fire_event_{timeout,socket}.
1263 The existing blocking event handler, ZOOM_event, is a wrapper for the
1264 + blocking ZOOM_event_sys_{poll,select}.
1266 Implemented function ccl_xml_config which parses XML version of CCL
1267 configuration (bug #798).
1269 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1271 Added timings utility (yaz/timing.h)
1273 --- 2.1.44 2007/01/03
1275 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1278 Fixed bug #779: Rotation of apdu.log fails.
1280 Fixed for character set conversions:
1281 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1282 Honor G1 set in MARC-8 decoding.
1284 --- 2.1.42 2006/12/17
1286 Fixed bug #775: char conversion does not handle Alternative UTF-8
1289 Implemented function yaz_marc_read_line which parses MARC line format
1290 records. There is a wealth of formats out there. So far, this function
1291 reads line records produced by yaz_marc_write_line.
1293 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1294 more generic and easier to remember(!) options: -i format and -o format
1295 which specifies input format and output format respectively - where
1296 format is one of "marc", "marcxml", "line", "marcxchange".
1298 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1299 does not print anything except warnings for records.
1301 For yaz-marcdump, added support for MARC split into files (-s) with a given
1304 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1305 spec, at http://www.loc.gov/standards/sru/record-update/
1306 This has changed the binary layout of the following structs:
1307 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1308 bend_update_rr . Patch by Ko van der Sloot.
1310 Added GFS utility function bend_assoc_is_alive which returns 1 if
1311 association is still alive (client is connected); 0 otherwise (client
1312 closed connection). This allows busy servers to stop working for
1315 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1316 been a separate piece of software. This version of ziffy has been modified
1317 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1319 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1321 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1322 Client code may now interrogate options such as "init_opt_sort" to
1323 find out whether the server claims to support various options.
1325 --- 2.1.40 2006/11/27
1327 Added utilities yaz_{set,get}_esn to set/get element set name from
1330 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1331 of YAZ and has been so since YAZ 2.1.10.
1333 Implemented ZOOM_record_error which returns error information for
1334 record (surrogate diagnostic).
1336 --- 2.1.38 2006/10/31
1338 Updates for SRU Update by Ko van der Sloot:
1339 1. Changed name from "operation" to "action"
1340 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1341 versions in the code, marked as 'backward compatible'.
1342 3. Added diagnostics for SRU Update.
1344 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1346 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1348 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1350 For GFS, fixed problem with SRU diagnostic 'First record position out of
1351 range' being issued for 0 hits.
1353 zoomtst10 part of Windows Build.
1355 --- 2.1.36 2006/10/13
1357 Implemented yaz_filepath_comp which splits a path into file path
1358 components (required by Zebra 2.0.3+).
1360 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1361 BSD inspired license until now so this should not have any real impact on
1362 anybody. See http://www.opensource.org/licenses/bsd-license.php
1364 Fixed bug #687: Missing log lines.
1366 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1369 Fixed bug #689: SRU diagnostics to be added.
1371 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1372 whether a connection is idle (no more work do do).
1374 --- 2.1.34 2006/10/04
1376 Change type of optval from long to int for invocation of setsockopt with
1377 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1379 Added support for specifying the max log file size for the Generic
1380 Frontend Server. The size is given with option -r.
1382 --- 2.1.32 2006/09/21
1384 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1386 --- 2.1.30 2006/09/17
1388 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1391 Fixed bug in Generic Frontend Server that could cause a server to stop
1392 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1394 For the generic frontend server, the maximum record size is used as maximum
1395 size of incoming packages (SRU + Z39.50). The value until was previously
1396 only used in Z39.50 Init negotiation and, later, in a session controlled
1397 sizes of records returned. This is controlled using -k option. It can be
1398 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1400 --- 2.1.28 2006/09/04
1402 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1405 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1407 New option for yaz-marcdump -lpos=value which allows setting a portion
1408 of MARC header to a certain value.
1410 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1412 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1413 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1415 --- 2.1.26 2006/08/15
1417 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1420 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1422 --- 2.1.24 2006/08/08
1424 Fixed MARC ISO2709 encoding routines to deal with character set
1427 Minor changes to GFS logging. Database included in search request log
1430 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1431 cached/multiple records.
1433 Shared libraries are built by default on Unix+configure.
1435 Changed cql2pqf transformation to use a different evaluation order. The
1436 new order is: always, relation, structure, position, truncation, index
1437 and relationModifier. Old order was: always, relation, relationModifier,
1438 structure, index, position, truncation. Note that the the latter ones
1439 override former ones for identical attributes.. The new scheme means that
1440 it is possible to override any existing attribute with a relationModifier.
1441 And also that it is possible to override everything for the index rule
1442 (except the ones listed in relationModifier). No order is perfect but this
1443 one, we believe, covers more real cases.. The "always" should have been
1444 called "default", since the attributes there can be overridden with all
1447 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1448 compilation phase, but also for yaz-config --cflags output. This allows
1449 us to have public headers with Libxml2 stuff in them . It should also,
1450 eventually, make Libxml2 checks redundant in packages using YAZ, such
1453 --- 2.1.22 2006/06/15
1455 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1456 stored in uri, message and details.. Previously diagnostics were stored
1457 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1458 compatibility.. but he's probably the only one affected, so.
1460 Added support for CCL, compiled on the client side, in ZOOM-C. This
1461 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1462 input; the resulting query objects can be used for for searching with
1463 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1465 YAZ' configure searches for OpenSSL by default.
1467 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1468 SL_CTX_use_certificate_file. See
1469 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1470 for more info. Thanks to Ko van der Sloot.
1472 --- 2.1.20 2006/06/02
1474 Bug #600: SRU GET, POST support for yaz-client. Introduced
1475 command 'sru' which selects method SOAP/GET/POST.
1477 Allow missingValueAction to be specified for the sortspec string -
1478 function yaz_sort_spec. By default, the missing value action is null.
1479 Use ! to specify "abort". Use = followed by stringvalue to specify default
1482 Ensured that Present-handler (if defined) is called in GFS before any call to
1483 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1484 searchRetrieve requests.
1486 Documentation for YAZ is now based on the Docbook XML/XSLT using
1487 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1488 is no longer depending on jade/openjade or docbook-to-man scripts.
1489 PDF is no longer part of the distribution - but can optionally be
1490 made using DSSSL/jadetex or FOP.
1492 Added retrieval handling support in Generic Frontend Server to support
1493 conversion between MARC/XML as well as XSLTtransforms. See
1494 etc/yazgfs.xml for an example.
1496 Added Authentication support to Generic Frontend Server in SRU
1497 mode. Authentication using HTTP Basic is supported, as is the use
1498 of 'x-username' and 'x-password' parameters in the request itself.
1500 Added support for a new character set MARC8s identical to MARC8 except
1501 that it converts combined characters to single Unicode characters in the
1502 Latin-1 range (when possible).
1504 --- 2.1.18 2006/04/24
1506 ASN.1 compiler 0.4: generates brief Doxygen file header for
1507 generated .h/.c files.
1509 Utility yaz_iconv now supports conversion to MARC-8.
1511 New facilities for the MARC module. The reading - and writing of
1512 content are separate methods for the yaz_marc_t handle. The following
1513 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1514 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1515 format). Write functions have prefix yaz_marc_write_.. The existing
1516 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1517 available. Removed support for OAI-MARC and simplexml (not the
1518 simplexml from PHP5).
1520 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1521 to be returned for this connection.
1523 --- 2.1.16 2006/03/31
1525 Allow multiple languages and charsets to be specified with
1526 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1527 negcharset iso-8859-1,utf-8
1529 Translation of proximity nodes from CQL into PQF now works.
1531 Moved to automake 1.8, 1.9.
1533 Added function yaz_log_set_handler which allows a log handler to be
1534 installed. This handler will be called for all log messages. Output
1535 to file is also produced; but that can be disabled by passing NULL
1536 fname to yaz_log_init_file.
1538 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1540 For SRW (including GFS), accept application/soap+xml as content-type
1543 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1544 produces NO stylesheet reference even if a default stylesheet is specified
1547 --- 2.1.14 2006/03/14
1549 Updated Windows package to include yazd.dll + yazd.lib for the
1550 Development component.
1552 If the environment variable YAZ_LOG is set, then it is used as a
1553 string indicating the default level of logging to use if not
1554 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1555 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1556 used as before. So, for example, to omit warnings from YAZ logging,
1557 export YAZ_LOG=-warn
1559 cql_transform() now map structure and other attributes before indexes,
1560 so that index-specific structures and other attributes can override
1561 defaults. So now a combination of mapping specifications such as:
1563 index.dc.date = 1=date-modified 4=5
1564 does the right thing.
1566 cql_transform() now also respects the "always" mapping specification,
1567 which establishes an initial set of attributes to be used for all
1568 terms except where overridden by more specific attributes associated
1569 with the index, relation or modifier.
1571 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1572 which mode to use; one of "post", "get" or "soap" (SRW, default).
1574 Fixes for yaz_iconv routines: changed trie-based character set conversions
1575 to use only non-negative values for bit fields due to Sun's C compiler not
1576 supporting negative values.
1578 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1579 sequences where not read correctly. Fix by Rustam Usmanov.
1581 Updated win/makefile to use options, settings which makes things
1582 compile with VS C 2005.
1584 --- 2.1.12 2006/02/01
1586 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1588 In ZOOM socket code, use select instead of poll on MacOSX.
1590 ZOOM-C now support client-side compilation of CQL into RPN that is
1591 sent to the server, enabling CQL to be used against all Z39.50
1592 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1593 ZOOM_query object, and submit it using ZOOM_connection_search().
1594 The CQL-to-RPN translation uses a configuration file, the name of
1595 which must be specified in the Connection's "cqlfile" option.
1597 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1598 function, which takes as its start-term parameter a ZOOM_query object
1599 (which may have had either CQL or RPN set into it).
1602 --- 2.1.10 2005/11/29
1604 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1605 GFS to support this as well. Backend handler, bend_srw_update, does the
1606 update work. Code contributed by Ko van der Sloot.
1608 Allow retrieval of Search Result-1 information in ZOOM by the use of
1609 options that are attached to a result set. ZOOM documentation updated
1612 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1613 UTF-8 conversion. Patch by Raj Patel.
1615 Added option -m to GFS to control formatting of timestamps in log file.
1617 Added 'exit' as synonym for 'quit' in yaz-client
1619 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1620 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1621 for the new members. Patch by Ko van der Sloot.
1623 Added support for SRU POST. It is supported for content-type
1624 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1626 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1627 Instead make the library libyaz.la multi-threaded. Threading as a whole
1628 can still be disabled by configure option --disable-threads. Previosly,
1629 with older GLIBCs there were problems with MT libs under Apache. This
1630 has now been fixed a long time ago.
1632 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1635 CQL module modified to be case insensitive for relations/indexes/operations.
1637 Fixed bug in CQL transform code: incorrect value relationModifieder
1640 Added 'show all' command for yaz-client which retrieves all results
1643 Added new yaz-client, xmles, which takes a (private) OID and
1644 a document to be sent as an extended service request.
1646 Describe new yaz-client commands wait_response and set_auto_wait.
1648 Increase TCP/IP listener backlog from 3 (which I am guessing was
1649 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1650 that the socket will queue as many incoming connections as it's able
1651 to handle ongoing connections. In other words, it will never now
1652 refuse a connection that it would be able to handle merely because
1653 it's not got around to accepting() enough of the pending connections
1654 yet. This is the behaviour anyway under Linux, where the listen()
1655 argument is ignored; but not under BSD and on systems such as
1656 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1657 YAZ-based servers should now be uniform across operating systems in
1660 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1661 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1662 This allows yaz-marcdump to read large MARC batches (>2 GB).
1664 Modified all YAZ source files - except the source which is auto-generated
1665 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1668 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1669 corresponding to the existing *_setl() function. These allow option
1670 values containing arbitrary valuues.
1672 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1673 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1674 except that it returns an indicator of whether or not the sort
1675 criterion was accepted (0 for OK, -1 for invalid).
1677 --- 2.1.8 2005/06/07
1679 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1680 MARC output rather than returning "new" buffer.
1682 yaz-client warns about unknown init options.
1684 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1686 --- 2.1.6 2005/05/24
1688 Added support for SRW sort in Generic Frontend Server. Patch
1689 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1690 sortKeys - or NULL if none is provided.
1692 Fixed bug #307: It was impossible to specify indefinite/no timeout
1693 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1696 Added support for multiple languages and charsets to be specified in
1697 ZOOM. Each charset/language is separated by a blank. If negotiation is
1698 in effect in init-response, Option
1699 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1700 Code based on patch by Vasiliy Osadchuk.
1702 Fixed bug #306: infinite recursion that occurred when calling
1703 yaz_log_level_init as the first call (before other log level or
1706 Fixed bug in scan handling in front end server: if preferred-Position-In-
1707 Response was non-present, a NULL pointer referece was performed.
1709 --- 2.1.4 2005/04/26
1711 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1712 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1713 now defined for all those error codes. So instead of putting 109 in
1714 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1715 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1717 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1720 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1722 Program yaz-client now exits and produces an error message if multiple
1723 Z39.50 servers are specified on the command line (none or one allowed
1726 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1729 --- 2.1.2 2005/03/16
1731 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1733 Fixed bug #272: Preserve spacing for CCL terms.
1735 --- 2.1.0 2005/03/14
1737 Added support for virtual hosts and multiple backend servers for
1738 the YAZ frontend server. The configution is XML based and
1739 support specificition of CQL to RPN mappings and explain information.
1740 See section "Virtual Hosts" in the YAZ manual.
1742 Extended OPAC display utility. OPAC display utility renders
1743 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1744 to supplement yaz_marc_decode_wrbuf.
1746 Fixed a bug in MARC decoder that could caused it to crash for some
1747 invalid MARC records. More diagnostics and warnings where added in
1748 XML output (warnings, etc are stored in comments).
1750 --- 2.0.34 2005/02/08
1752 Fixes for UNIX domain sockets. Bug #261.
1754 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1756 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1757 Added yaz_marc_subfield_str which defines subfield lead string which is
1758 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1759 yaz_marc_endline_str which defines end of fields string used in
1760 YAZ_MARC_LINE format. Default string is newline.
1762 Experimental support for MarcXChange. This format can be produced
1763 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1764 http://www.bs.dk/standards/MarcXchange.xsd
1766 Added yaz-client commands scansize that sets maximum number of
1767 entries to be returned by scan.
1769 --- 2.0.32 2005/01/11
1771 Added support for SRW scan in yaz-client and Generic Frontend Server.
1773 * Added whereInList member to SRW Scan Term.
1775 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1777 Fixed NMEM system to return aligned blocks on the smallest boundaries
1778 that are suitably aligned for all possible types on the particular
1779 architecture YAZ is being built for.
1781 --- 2.0.30 2005/01/04
1783 Fixed numerious warnings that was issued with newer versions of GCC.
1785 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1786 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1789 Make YAZ Generic Frontend Server slightly faster.
1791 Enhance (and reduce) logging for Generic Frontend Server.
1793 Revert YAZ log system so that it flushes every write operation
1794 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1796 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1797 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1798 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1799 will effectively disable old definitions.
1801 --- 2.0.28 2004/11/09
1803 Added yaz_log_time_format which specifies log format using
1806 Added yaz_log_module_level which returns mask for a module. Value
1807 is non-zero mask a if module is enabled; zero if disabled.
1809 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1810 in include/yaz/cql.h.
1812 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1814 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1816 Fixed bug #172: RPM builds does not enable SSL.
1818 Doxyfile.in part of dist. Doxyfile generated by configure.
1820 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1821 are given and the corresponding component does not exist.
1823 Extend CCL documentation in YAZ reference. Describe r=r.
1825 --- 2.0.26 2004/10/01
1827 Fixed MARC->MARCXML conversion to properly deal with
1828 fields, subfields, indicators having non-ASCII characters.
1830 Fixed MARC->MARCXML conversion so that ASCII control characters
1831 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1834 Added YAZ GFS support for conversion from Z39.50 surrogate
1835 diagnostics to SRW surrogate diagnostics.
1837 Bug fix: YAZ GFS did not return schema in explainResponse.
1839 --- 2.0.25 2004/09/30
1841 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1842 now converts recordSchema to elementSetName as well as schema URI.
1844 Fixed bug in COMSTACK that prevented HTTP request packages from being
1847 --- 2.0.24 2004/09/29
1849 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1850 does not require white-space before and after the dash in a range, e.g.
1851 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1854 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1855 due to new GCC removing "redundant" code.
1857 Added yaz-client commands scanpos and scanstep that sets preferred
1858 position and step-size for scan.
1860 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1862 Added CCL utility ccl_qual_buf which parses one or more CCL
1863 spec lines in a buffer.
1865 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1866 of name and value - ignoring empty lines and comments.
1868 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1870 Added odr_get_element_path which returns current element path for an
1871 ODR handle. This utility is useful in error handling or user-defined
1874 Added ODR_PRINT utility odr_set_stream which is is a more generic
1875 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1876 to a write function and pointer to close function. The close function - if
1877 non-NULL - will be called during odr_destroy.
1879 Fixed bug in CCL parser where truncation char was not removed from
1880 right side when truncation=both was in effect.
1882 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1885 --- 2.0.23 2004/08/11
1887 Fix buffer overrun in CQL parser when dealing with proximity (%).
1889 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1890 to UTF-8/UCS conversion is now only based on codetables.xml.
1892 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1894 --- 2.0.22 2004/08/06
1896 Add support for more "commit changes" in ZOOM (uses Extended Services).
1898 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1901 Yet another small fix for configure of SSL.
1903 --- 2.0.21 2004/05/14
1905 Fix SSL libs for configure when --with-openssl=DIR is given.
1907 --- 2.0.20 2004/05/10
1909 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1911 SSL comstack now uses yaz.pem certificate file on server side
1912 by default. Certificate filename can be configured by calling
1913 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1915 Fix bug regarding multiple calls to ZOOM_connection_connect.
1917 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1919 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1920 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1922 ZOOM now allows inspection of X509 peer certificate for verification.
1923 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1925 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1926 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1927 as "modular" but it simplifies things.
1929 Added cs_get_peer_certificate to that returns peer X509 PEM.
1931 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1932 NULL if SSL is unavailable.
1934 Documentation about MARC decoding tools.
1936 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1938 --- 2.0.19 2004/03/30
1940 Rename CHANGELOG to NEWS to follow GNU style packing.
1942 Fix bug with missing initialization of member in init_diagnostics.
1943 This bug affects threaded version of GFS server.
1945 --- 2.0.18 2004/03/20
1947 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1950 Ensure zlib.dll is packed with Windows install.
1952 --- 2.0.17 2004/03/17
1954 Fix encoding of xsd:string to use text instead of CDATA.
1956 Fix endless loop in CQL parser with unbalanced ".
1958 Use a more compact way to store MARC-8 conversion tables.
1960 --- 2.0.16 2004/03/16 Debian only
1962 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1965 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1970 --- 2.0.15 2004/03/01
1972 Another fix for decoding of XML packed records.
1974 --- 2.0.14 2004/02/25
1976 Fixes for Chunked encoding. White space not ignored after length spec.
1978 Update NS and use default NS for SRW diagnostic elements.
1980 --- 2.0.13 2004/02/23
1982 Implement ZOOM_resultset_cache_reset which resets record cache.
1984 Implement ZOOM_resultset_sort which sorts a result set.
1986 Implement chunked HTTP transfer.
1988 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1990 --- 2.0.12 2004/02/16
1992 Added member 'schema' to bend_explain_rr structure so that backend
1993 can specify explain record identifier. Defaults to Zeerex 2.0.
1995 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1997 --- 2.0.11 2004/02/16
1999 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2002 Added init command for yaz-client which sends "extra" init request.
2004 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2005 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2007 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2009 Make ZOOM error code for "invalid query".
2011 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2013 --- 2.0.10 2004/02/05
2015 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2018 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2020 Added option -p <file> to make Generic Frontend Server to write PID file.
2022 Added option -D to put Generic Frontend Server in background on its own.
2024 Make ZOOM C recognize option "password". If unset, "pass" is used
2025 (for backwards compatibility).
2027 Fixed a bug in Generic Frontend Server that could make it crash if a
2028 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2031 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2032 Must be issued before open, in order to be in effect.
2034 --- 2.0.9-6 2004/01/12 Debian/Windows
2036 Make the SRU server more picky WRT unknown params, etc.
2038 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2040 New YAZ client command, options, that sets Z39.50 options.
2042 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2043 options from a string of tokens (one token for each option bit).
2045 Update SRW diagnostic code messages.
2047 --- 2.0.9-5 2004/01/07 Debian/Windows
2049 Handle user defined stylesheet for SRW/SRU.
2051 --- 2.0.9-4 2004/01/06 Debian/Windows
2053 Fix bug in decoding of Content-Length.
2055 --- 2.0.9-3 2004/01/06 Debian/Windows
2057 Fix a bug with decoding of XML packed records.
2059 --- 2.0.9-2 2004/01/05 Debian only
2061 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2063 Fix bug in SRW/SRU diagnostics decoding.
2065 --- 2.0.9 2004/01/05
2067 Fixed bug in Generic Frontend Server which could drop records exceeding
2068 preferred message size. Reported and fixed by Irina Dijour.
2070 Fixed calculation of package size for structured records in Generic
2071 Frontend Server. Reported and fixed by Irina Dijour.
2073 Fixed namespace for SRW/SRU diagnostics.
2075 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2077 --- 2.0.8 2003/12/22
2079 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2080 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2083 CQL changes to reflect recent changes to the specification:
2084 * Documentation talks about context sets instead of index sets.
2085 * Documentation talks about indexes instead of qualifiers.
2086 * The CQL-to-PQF transformer's configuration file now uses
2087 "index.set.name = <attributes>" instead of the old form
2088 "qualifier.set.name = <attributes>". (Both forms are still
2089 understood but the latter is deprecated.)
2090 * CQL terms with no explicit index specified are now interpreted as
2091 cql.serverChoice instead of srw.serverChoice (which of course
2092 behaves exactly the same.)
2094 --- 2.0.7 2003/12/16
2096 MARC conversion can now generate ISO2709 output in another
2097 character set. yaz-marcdump uses this facility if you invoke it
2100 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2101 functions from there can be used from C++.
2103 --- 2.0.6 2003/12/04
2105 Frontend server now transfers memory from decoded packages to stream
2108 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2109 references to show up.
2111 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2112 the ZOOM Abstract API. The older names for the same options are still
2113 also supported for the benefit of old applications.
2115 ZOOM-C supports "implementationId" and "implementationVersion" options
2116 to go along with "implementationName". These allow the user code to
2117 specify identification strings to be sent to servers.
2118 Add OID for the new ExtLite attribute set.
2120 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2121 as requested/supplid by Ere Maijala <ere@atp.fi>
2123 For generic frontend server, reverse the order of
2124 "toolkit-supplied / application-supplied" strings sent as implementationId,
2125 Name and Version. Also, remove the spaces around the slash. This brings
2126 the GFS in line with the behaviour of ZOOM-C on the client side.
2128 Add function ZOOM_scanset_display_term.
2130 yaz-client shows scan displayTerm if present.
2132 Utility yaz-iconv is now installed by default along with the man page
2135 Extend configure check for OpenSSL to use pkg-config where available (such
2138 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2139 server to specify uid/gid/mask for socket using the format
2140 unix:[user=uid,][group=gid,][umask=mask,]file=path
2141 If file= is omitted the existing format is assumed, e.g.
2143 in which case the mask is 0666 (rw for everybody).
2145 Major restructure of YAZ source. All source in libyaz is in src directory.
2146 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2147 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2149 Added man page for utility yaz-marcdump (used to be called marcdump).
2150 yaz-marcdump is installed by 'make install'.
2152 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2153 of incoming package failed.
2155 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2157 Change prototype of odr_perror: add const to message string.
2159 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2161 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2162 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2163 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2164 DNS lookup. There should not be any compatibility problems with this
2165 assuming that blocking=1 or 0 is used.
2167 Fix bad reference in UNIX comstack in function cs_addrstr.
2169 Fix for compilation on AIX.
2171 The generic front-end server (server/seshigh.c) now supports returning
2172 Init diagnostics to the client in User-information-field, in
2173 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2176 --- 2.0.4 2003/09/04
2178 Allow any CQL relation (not just all,any,exact,scr).
2180 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2181 that features the same UI.
2183 Implemented command update0 in YAZ client which is equivalent to
2184 update but uses old of Ext Update ASN.1.
2186 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2187 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2188 Previously no OID was used for this info.
2190 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2191 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2192 returns 'malformed search term' otherwise.
2194 SortResponse member resultCount now set to NULL in sort handler of
2197 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2200 Add three new utility functions for translating OIDs between various
2201 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2202 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2203 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2204 char *oid_to_dotstring(const int *oid, char *oidbuf);
2205 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2207 Reverted modifications for ES Update definition for z_IU0Update
2208 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2209 is back to YAZ 2.0.2.
2211 String value attributes for CCL parser.
2213 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2214 which their FirstSearch server returns in Init responses, sometimes
2215 carrying useful diagnostic information when Init fails. This has the
2216 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2217 "z39.50/oclcui.asn", where its definition is somewhat different from
2218 what OCLC document on their web-site, as required to interoperate with
2221 Support for anonymous authentication in yaz-client. Use the command
2224 * Fix the OID of the Index Data-local "admin" Extended Service from
2225 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2226 the 1000, which indicates a locally-defined OID, was a mistake.
2228 --- 2.0.3 2003/06/20
2230 Fix CCL directive @case handling so that it affects string match for
2231 both CCL keywords and qualifiers.
2233 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2234 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2235 Decoder has been updated with ASN.1 changes as listed in
2236 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2237 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2238 z_IUUpdate, remains unchanged.
2240 ZOOM_record_get may now return a record in a specific character set.
2241 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2242 "from" is the character set of record as returned by target. "to" is
2243 the character set to be returned. If omitted, "to" is UTF-8.
2245 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2247 New ODR utility, odr_getelement, which returns name of element for
2248 which encoding/decoding failed.
2250 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2251 in cases where a required element was omitted.
2253 Bug fix: some MARC8 sequences were not converted.
2255 New ZOOM option "step" which specifies number of records to be
2256 retrieved in one chunk. Used in conjunction with "start" and "count".
2258 SRW support for yaz-client. Use scheme http: to use it, e.g.
2261 yaz-client no longer does (un)intelligent character set conversions
2262 by default. Can be enabled with charset and marc_charset commands.
2264 xmalloc trace fix for 64-bit systems such as DEC alpha.
2266 Solaris 2.6 compile fix.
2268 New function, cql_strerror() translates SRW error codes, as returned
2269 by cql_transform_error(), into human-readable English strings. Used
2270 in yaz-client diagnostics when appropriate.
2272 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2273 converts it into a type-1 query which is sent to the server. This
2274 makes CQL available for use with all Z-servers, as opposed to the tiny
2275 minority that can handle CQL queries themselves.
2277 --- 2.0.2 2003/04/28
2279 New Debian package layout similar to the Redhat Package layout.
2281 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2282 and search result respectively.
2284 --- 2.0.1 2003/04/25
2286 Redhat package is now several packages: libyaz (runtime libraries),
2287 libyaz-devel (development and documentation, and yaz (utility programs).
2288 Package spec file by Morten Bogeskov.
2290 New member 'schema' in struct bend_fetch_rr which the name of requested
2291 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2292 handler MAY set this to reflect the schema of the returned record.
2294 New member 'display_term' in struct scan_entry. GFS now sets member entries
2295 and allocates scan entries to be filled by user scan handler. In previous
2296 version, entries member was allocated by the scan handler. That still works,
2297 but the GFS will ignore member display_term - assuming it was NOT set by
2298 the handler. The fact that the GFS now allocates the entries both allows
2299 for new members and makes a scan handler easier to write.
2301 Fix CQL lex buffer overflow.
2303 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2304 SRU default recordPacking is string.
2306 SRU protocol support for frontend server.
2308 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2310 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2312 Added scan for the ZOOM shell (zoomsh).
2316 * String Identifers for Schemas (Amendment 5).
2317 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2318 Old definition for schema
2319 Odr_oid *schema; /* OPT */
2324 Z_InternationalString *uri;
2325 #define Z_Schema_oid 1
2326 #define Z_Schema_uri 2
2329 * resultCount parameter to Sort Response (Amendment 1).
2330 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2332 Support for SRW 1.0 over HTTP. This is an optional feature and
2333 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2336 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2337 on the same port. SRW SearchRetrieveRequests are mapped
2338 to bend_init,bend_search,bend_fetch,bend_close.
2340 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2342 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2343 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2345 ZOOM connections are SRW based if schem http is used for hostname
2346 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2347 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2349 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2350 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2351 distance=n, order=true/false, relation=le, prox unit=word. If
2352 n is omitted, distance 1 is used.
2354 Fixed problem with C compiler include path in wrong order.
2356 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2357 on Solaris. Patch from Ko van der Sloot.
2359 New MARC decode API. All new functions operate on a yaz_marc_t
2360 handle. The most important new functions are: yaz_marc_create,
2361 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2362 decode and destroy respectively. Decoder can produce formats
2363 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2364 include/yaz/marcdisp.h.
2366 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2367 to UTF-8, UCS-32, wchar_t or Latin-1.
2369 * Prototypes for yaz_iconv_-functions moved to separate header
2370 include/yaz/yaz-iconv.h.
2372 Make a few private functions 'static' in unix.c. This prevents
2373 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2375 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2376 are set when Init Response is received.
2378 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2379 but returns diagnostic set as well.
2381 New function yaz_strerror which is a portable wrapper for
2382 strerror/strerror_r/GetLastMessage.
2384 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2385 is returned for MARC. If type is "oai", then OAI MARC is returned.
2387 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2390 --- 1.9.2 2002/11/26
2392 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2394 Fix bad race conditions on SIGTERM and terminate gracefully in
2397 Move retrieval (data1) module to Zebra since nobody seems to be
2400 Add GRS-1 render for ZOOM using same format as yaz-client.
2402 --- 1.9.1 2002/10/05
2404 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2406 Fix broken ESpec handling in data1 module.
2408 SGML reader parses comments and makes them part of the data1 tree.
2410 Added several type casts so that YAZ compiles as C++ code.
2412 ZOOM didn't handle PDU encoding failures properly.
2414 Added more Bib-1 diagnostics (approved extensions).
2416 GNU configure: better check for iconv.
2418 More portable use of accept, getpeername. Check for socklen_t. Use
2419 int/size_t if socklen_t is not defined.
2423 PQF parser rejects bad queries - including those with extra
2424 characters in them. PQF parser used to silently ignore that.
2425 Cleaner API for PQF added, which allows you to get detailed
2426 error information for bad queries (see yaz/pquery.h).
2428 Fixed bug in ZOOM_record_get for type "database".
2430 Implemented mini iconv library supporting conversions between
2431 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2433 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2435 --- 1.8.9 2002/08/20
2437 Fixed ZOOM C record cache so that preferredRecordSyntax and
2438 elementSetName is used to check for already fetched records.
2440 --- 1.8.8 2002/08/02
2442 Added three members in bend_initrequest structure to facilitate
2443 character set negotiation.
2445 Fixed a bug in frontend server that could cause indefinite
2446 loops under rare conditions.
2448 Revised character set utilities (charneg.h) so that encoding
2449 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2451 For PQF, directive @term <type> sets term type for Scan/Search.
2452 Here <type> is general, string, numeric, null. The term type
2453 is inherited - just like @attr.
2455 New call odr_set_charset that sets character set conversion for
2456 international-strings on a ODR stream. Prototype is:
2457 int odr_set_charset(ODR o, const char *to, const char *from);
2458 The InternationalString is still represented as C string in YAZ
2459 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2460 won't). On the protocol level, you can use any encoding.
2462 Support for UNIX sockets in ZOOM.
2464 Solaris recv sometimes returns errno == ENOENT. It is treated as
2465 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2467 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2468 both client and server. Code by Morten Bogeskov.
2470 --- 1.8.7 2002/05/22
2472 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2473 that they can be used directly from Visual Basic. You must recompile
2474 your windows APP if you're using ZOOM.
2476 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2477 Commands "lang" and "charset" sets language and character set respectively.
2478 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2479 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2481 Attributes from multiple CCL fields may be OR'ed rather than merged
2482 using directive "@field or". Fields are still merged by default -
2483 equivalent to "@field merge".
2485 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2488 Fixed bug in zget for parameter ExtendedServicesResponse.
2492 --- 1.8.6 2002/03/25
2494 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2496 Client displays USR.1:SearchResult-1 (hits per term).
2498 Additional Search Info for search in Generic Frontend Server.
2500 Fixed CCL parsing of "field=s".
2502 WIN32 installer - using the excellent NSIS software from nullsoft.
2504 Fixed CCL parsing of "field = - <number>".
2506 Added function yaz_marc_decode that decodes MARC for line mode
2507 display or XML (similar to that used by JZKit).
2509 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2510 Z39.50. But ISO/ILL was, however.
2512 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2513 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

2518 --- 1.8.5 2002/02/03
2520 New YAZ client features: Command completion and new commands:
2521 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2522 Code provided by Jacob Poulsen.
2524 New call oid_trav, that visits all registered OIDs via callback.
2526 Function ZOOM_record_get now returns const char pointer rather than
2527 void pointer. It saves a lot of type casts.
2529 For YAZ client, command "auth" now allows you to set authentication
2530 in IdPass style. It is enabled when three tokens are given - order
2531 is user, group and password.
2533 Fix memory leaks in MARC record handling for ZOOM.
2535 New option for YAZ client, -k <kilobytes> that sets
2536 maximum record size. Similar to -k option for generic frontend
2537 server and yaz-ztest.
2539 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2541 Prefix query parser reports "fail" when bad attribute set is given.
2543 Fix in MARC decoder. Proximity logging. Fix for attribute set
2544 in scan handler for server. Patches by Shigeru Ishida.
2546 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2549 Configure option --with-openssl=<dir> now works when a directory is
2550 specified. Patch provided by Morten Bogeskov.
2552 New option for YAZ client, -u <auth>, that sets authentication.
2554 ZOOM fix: error information was sometimes "missing", since error
2555 was cleared/reset too when it shouldn't.
2557 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2559 --- 1.8.4 2002/01/04
2561 Scan for ZOOM API. New object ZOOM_scanset. New functions
2562 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2563 ZOOM_scanset_destroy.
2565 New ZOOM function, ZOOM_connection_last_event, that returns type
2566 of last event (such as "receive data", "send data", "apdu received",
2569 New ZOOM option, schema, that specifies schema for retrieval.
2571 New CCL feature. Qualifiers can be aliases for one or more
2572 other qualifiers (if more than one is given, OR is used).
2574 ZOOM uses named result sets if target supports it.
2576 Two new YAZ client commands: . (dot, which sources a script of YAZ
2577 client commands), and ! (to execute shell command.). Implemented
2580 Working on Debian packages.
2582 --- 1.8.3 2001/11/19
2584 YAZ client enables named result sets only if target supports it.
2586 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2588 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2589 with key="host" to get same result.
2591 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2592 Function Z3950_resultset_record(s) returns references to records
2593 "owned" by resultset. To become owner use Z3950_record_clone.
2595 Function z_ext_record handles Extended Services. Thanks to
2598 --- 1.8.2 2001/11/12
2600 CCL Parser fix: ignore token comma when dealing with and-lists.
2602 Documentation updates for COMSTACK.
2604 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2605 Changed prototype Z3950_records. For some functions, int parameters
2606 were changed to size_t.
2608 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2611 New MARC decode/display function, marc_display_exl, which properly rejects
2612 non-ISO2709 records. YAZ client uses it.
2614 --- 1.8.1 2001/10/29
2616 Fix bug: local attribute set wasn't set correctly in PQF strings.
2620 * Old Z39.50 codecs no longer supported.
2622 Added ZOOM C binding. See http://zoom.z3950.org/
2624 Renamed states for COMSTACKs to avoid confusion with events.
2626 Implemented cs_look and proper cs_rcvconnect.
2628 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2630 Configure detects POSIX threads on OpenBSD.
2632 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2633 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2635 When error is returned from present handler, non-surrogate diagnostic
2636 is returned in present response (and fetch handler is no longer called).
2638 * Minor adjustments to pquery parser (PQF). Token characters may be
2639 escaped by using backslash (C-style).
2641 PQF parser allows string attribute values to be specified. For @attr,
2642 non-numeric characters after the equal-sign are treated as strings
2643 (e.g. @attr 9=title).
2645 CCL trunction character may be defined (@truncation in file)
2647 * function zget_ExtendedServicesRequest sets waitAction to
2648 waitIfPossible (was wait).
2650 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2653 CCL operator names may be set in field definition files (CCL_bibset).
2654 See ccl/bib1 for an example.
2656 Fixes in ASN.1 compiler for C++ compatibility.
2658 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2659 and "op_or" to avoid conflict with C++.
2661 Fixed problem with GNU readline detection on Redhat 7.0.
2663 Added step-size for Scan backend handler.
2665 Fixed bug that made the frontend server crash when no attribute
2666 set was specified for scan.
2668 Front-end server automatically switches to original working directory
2669 when installed as an NT service. Previously -w had to be specified to
2672 Added extended attributes for retrieval module (data1), so that data1
2673 records carry d1_readXML/SGML attributes. d1_read also supports
2674 null-data rules ( <tag/>)
2676 On UNIX when POSIX threads are available, a separate library libyazthread
2677 is created. Programmers should link with that library and the yaz library
2678 when using threads. The reason for the split was that some applications
2679 on Linux, such as Apache, doesn't work well when using shared objects that
2682 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2683 (or any frontend server) in SSL mode by specifying ssl: followed by
2684 address. Only tested on UNIX.
2686 Added feature for CCL module. Virtual structure s=al or s=ol generates
2687 and-list and or-list respectively instead of phrase search.
2691 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2692 log_mask_str. This was done to avoid name conflicts with other libraries
2693 (such as other PHP extensions).
2695 Added raw OID member for preferred record syntax (request_format_raw)
2696 and returned record syntax (output_format_raw) for backend fetch method.
2698 Config file yaz-config now accepts options so that it returns specific
2699 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2701 Shared library support for UNIX using GNU libtool.
2703 * Modified backend interface. Request/Response struct's replaced by
2704 one read/write C struct. For example bend_fetchrequest and
2705 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2706 Every handler - even search has to be registered in bend_init
2707 handler. This means that the YAZ library no longer refers to
2708 external functions and it makes it possible to make the whole
2709 thing a single DLL/SO.
2711 Added Segment handler for backend server.
2713 Added Zmbol/Zebra administrative functions to YAZ client.
2715 Threaded frontend server on UNIX (when POSIX Threads are available).
2716 Starting the server with option -T enables multi-threading.
2720 Added configure option --enable-comp/disable-comp to control use
2721 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2722 located in sub directory asn.
2724 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2725 in ${exec_prefix}/bin along with the other programs yaz-client and
2728 GNU automake used to maintain makefiles.
2730 Added several OID's.
2732 Changed retrieval module so that we can load records with no abstract
2733 syntax defined. Tagpaths in these records are fully composed of string
2736 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2740 On UNIX, the generated makefile now supports a proper 'make install'.
2741 The prefix can be set via GNU configure to set the install location
2742 (default is /usr/local).
2744 * YAZ programs client and ztest were renamed to yaz-client and
2745 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2746 locations, such as /usr/bin,/usr/local/bin,etc.
2748 * YAZ Header files were moved from include to include/yaz. YAZ Header
2749 files are referred to as include <yaz/log.h> rather than <log.h>.
2750 The YAZ include path (-I ..) is therefore the same as before. Programmers
2751 should update their #include statements or use -Ipath/include/yaz
2752 instead. The main motivation for doing this change is that YAZ header files
2753 can be installed in "standard" locations /usr/include,/usr/local/include
2754 without introducing conflicts, since ALL YAZ header files are stored
2755 in subdirectory yaz (under /usr/include for example).
2757 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2758 rather than project/workspace files. We switched because project files
2759 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2762 Changed name of logging function, logf, to yaz_log, to prevent name
2763 clash with some math-log functions. The YAZ header log.h defines logf
2764 to yaz_log (#define) so there should be no incompatibilities by this
2767 Added bend_start/bend_stop handlers for server. These handler are
2768 called on start/stop of server. For windows they are called whenever
2769 a service is started/stopped.
2771 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2772 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2773 in util/yc.tcl. The auto-generated C code structures are, in a few
2774 cases, incompatible with the old decoders. There are differences in the
2775 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2776 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2777 The preprocessor variable ASN_COMPILED is defined when the compiled
2778 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2779 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2780 wish to use the old encoders/decoders you can specify --disable-yc
2783 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2784 version so that it supports both new - and old version of DB Update
2786 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2787 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2788 change. The name parameter can be set to 0 in which no name is specified
2789 for the construction. The macros odr_implicit and odr_explicit sets name
2790 parameter to zero for the construction involved. New macros
2791 odr_implicit_tag and odr_explicit_tag are similar to the others,
2792 except that a name parameter is added. For programmers' that don't use
2793 ODR they probably only need to change the call to z_APDU and z_External.
2795 Added access control facility by interfacing the TCP wrapper library.
2796 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2797 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2798 name of the daemon and enables the access control as specified in
2799 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2801 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2802 den Dool <H.M.vdnDool@kub.nl>.
2804 Added reference ID parameter to most functions in server API - refer
2805 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2807 Changed name of ccl library to libccl.a (was ccl.a).
2809 Fixed bug in decoder for Explain (Category TargetInfo).
2811 Added support for GNU readline in client. Thanks to Jacob Poulsen
2812 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2814 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2815 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2816 IMPLEMENTATION! This change was made to the development version before
2817 the ZIG decided to retract the amendment. If any users MUST be
2818 compatible with the original Update definition, PLEASE CONTACT US, and
2819 we will include a separate definition corresponding to the old Update
2820 ES. Note that because of the change to the ASN.1 of the
2821 TaskPackageRecordStructure we cannot define a single structure that
2822 will support both versions.
2824 * Added const modifier to buffer parameter for some ODR/BER encoding
2825 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2826 completeWAIS, odr_dumpBER.
2828 Fixed bug in client.c which caused a crash when a scanResponse didn't
2829 contain positionOfTerm.
2831 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2832 * will cause an error in a client if a non-YAZ target sends both a
2833 * list of Scan entries and non-surrogate diagnostics.
2835 Retrieval module enhancements. Tag sets may be typed in the reference
2836 to it. From the .abs-file the "tagset" directive takes a third optional
2837 integer type for the tag set referenced. From a .tag-file the "include"
2838 directive takes a third optional type as well. The old "type" directive
2839 in the tag set itself is still recognized but acts as the default type
2842 Backend interface change. Individual Scan terms returned from bend_scan
2843 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2844 in include/backend.h.
2846 Retrieval module enhancements. Multiple tag sets and attribute sets may
2847 be specified in abstract syntax specs. Revised the error/warning for
2848 logging messages reported by the retrieval module when reading the
2851 Object Identifier system (oid_..) changed. The API is backwards
2852 compatible but the oid-routines now allocates new OID's when needed.
2853 Raw OID's may be specified in oid_getvalbyname.
2855 YAZ now uses GNU configure to generate Makefile(s).
2857 * Minor changes in some of the member names of DeleteResultSetRequest and
2858 DeleteResultSetResponse. See include/proto.h.
2860 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2861 and added member 'languages' in TargetInfo (which was missing).
2863 Changed the way attribute sets are handled in the retrieval
2864 module. These are now cached, just like the abstract syntaxes
2867 Changed YAZ so that it links with compiled ASN.1.
2869 Added Explain-schema definitions and mapping routines. The following
2870 Explain categories have been implemented: AttributeDetails,
2871 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2873 Fixed minor bug in Windows version of Server Library.
2875 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2877 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2879 Added EXTERNAL: UNIverse Resource Report (non-standard).
2881 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2882 ENUMERATED and SET OF.
2884 * Added 'const' to some of the char pointer arguments for the
2885 functions, data1_read_node, data1_getelementbytagname,
2886 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2889 Fixed bug in data1_insert_taggeddata - the last_child member of
2890 parent wasn't initialised.
2892 * Changed data1_read_record and data1_read_node so that the supplied
2893 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2894 doesn't refer to any parts of the "SGML"-buffer.
2896 Fixed bug in server library (Windows version of statserv_remove).
2898 * Changed code so that it compiles as C++. The type definition
2899 of Odr_fun which is a member of Odr_arm was changed. The result is,
2900 that an explicit typecast is needed for the fun pointer when
2901 using Odr_arm - as in:
2902 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2904 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2906 Implemented the new structured date and time definition as approved
2907 by the ZIG. Added schemaId element to the specificTag in Espec-1
2908 (also approved at the last ZIG). Thanks to RVDM.
2910 Added some Object identifiers (RVDM).
2912 Changed the Update Extended Service (RVDM).
2914 Added command "refid" to client which specifies referenceId for
2915 the following requests.
2917 Implemented extended service handling for server. See ztest.c
2918 for an example as well as backend.h. New handlers are registerd
2919 in the Init handler.
2921 * Changed interface for sort in server.
2923 Added new members to statserv_options_block. It allows a server
2924 to read options from another source than just the command line. Thanks
2925 to Charles Woodfield.
2927 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2928 renamed to zboolean. Some C++ compilers complained about the name.
2930 Minor changes to gils.abs. Added index 's' (sort) on title
2931 and date/time-last-modified.
2933 --- 1.4pl2 1998/1/30
2935 Fixed bug in server library regarding inetd mode (-i). This bug
2936 was introduced by release 1.4.
2938 --- 1.4pl1 1998/1/29
2940 Added sort facility in client and backend server interface.
2942 Fixed problem with dependencies in Makefile(s).
2944 Fixed bugs for encoders/decoders of extended services and
2947 Implemented sub-tree feature for schemas. Sub-trees are
2948 referenced in *.abs-files. See explain.abs for an example
2949 of the use of this feature.
2951 Modified bib1.att; local attributes for ANY didn't include
2952 ANY itself (only affects use of the retrieval module).
2954 Fixed bug in plain SGML reader in function data1_read_node:
2955 tags with prefix "var" was incorrectly interpreted as variants.
2957 Added feature "sub-schemas" to enable references to - and definitions
2958 of - group of elements.
2960 * Removed member parent from type data1_element (in data1.h).
2962 Implemented function odr_nullval() that returns the value of
2965 * Removed member num_children from data1_node (in data1.h).
2967 Made NT service interface part of the server library. The
2968 function statserv_main uses the NT service when required and
2969 calls the statserv_start / statserv_close routines.
2971 Routine zget_SearchRequest and zget_PresentRequest fills
2972 resultSetName/Id member with "default" instead of "Default".
2974 Fixed memory leak in server. Request queue member wasn't freed.
2976 Fixed nmem_exit so that memory is freed.
2980 Revised the CCL parser utility to be thread safe.
2982 Added function, oid_ent_to_oid, to replace the function
2983 oid_getoidbyent, which is not thread safe.
2985 * Added nmem_init and nmem_exit to initialize and release
2986 NMEM resources. Function nmem_init should be called once in the
2987 initial thread before NMEM/ODR is used. statserv.c and client.c
2988 have been changed accordingly. The change was necessary to make
2989 NMEM thread safe. The NMEM memory pool is shared amongst threads
2990 in a process. Unix-based applications will still work fine without
2993 Added NT Services interface for the the Z39.50 (statserv) Server.
2994 Refer to the ztest.c source on the usage.
2996 Windows 95/NT port using MSVC5.0. Project files are included in the
2999 * Defined new 'global' handle for the retrieval (data1) system. The
3000 new handled, data1_handle, describes the state of the data1 system.
3001 This handle is passed as first argument to virtually all
3002 data1 related routines. The functions data1_create and data1_destroy
3003 creates and destroys a data1 handle respectively.
3005 Added ODR encode stream member to all backend request structures
3006 init, search, scan etc. This stream should be used to allocate all
3007 memory used for the response when thread safe operation is needed.
3009 Changed the comstack utility, cs_addstr, to be thread safe. The
3010 returned hostname string returned by the function is now part the
3013 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3014 function. The cs_straddr takes a COMSTACK handle as argument, so this
3015 function must be used after cs_create and before bind/connect.
3016 This function is thread safe.
3018 Moved test server to 'ztest' directory - generic server code still
3019 in 'server' directory.
3021 Made prefix query (pquery.c) utility thread safe.
3023 Added new function modifier YAZ_EXPORT to 'export' public DLL
3024 functions when using windows (see include/yconfig.h).
3026 Added definitions to the OID database (util/oid.c) (RVDM).
3028 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3030 Added call to ccl_rpn_delete in client program.
3032 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3033 release of RPN structure.
3035 Added support for C++, headers uses extern "C" for public definitions.
3036 With input from RVDM.
3038 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3039 Thanks to Ronald van der Meer (RVDM).
3041 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3043 Added support for private extensions to the OID database
3044 (oid_setprivateoids()). Thanks to RVDM.
3046 Added optional, physical ANY (key replication)
3048 Fixed null-reference problem in GRS-1 output filter.
3050 Proximity operator added to Prefix Query Format (PQF).
3052 In test client command "base" accepts multiple databases.
3054 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3058 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3060 Smallish bug-fixes in the new encoders/decoders (explain).
3062 Bug fixed in DeleteRequest.
3064 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3066 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3068 Added SOIF syntax (using private OID for now) to retrieval module and client.
3070 Added Update extended service.
3072 Added SearchResult-1 additional info structure.
3074 Added optional CCL (ISO8777) interpreter as separate module. Available
3077 --- 1.2 1996/6/10 (1st anniversary release)
3079 Added Summary record syntax. Lightly tested.
3081 Added OPAC record syntax. Untested.
3083 Added ResourceReport service encoders/decoders. Untested.
3085 Fixed bug in z_Unit - wrong tagging on unitSystem.
3087 Fixed bug in the DiagRecs decoder.
3089 Added options for max PDU size and session timeout to frontend-server.
3091 Added documentation of query-language parsers and other supporting utilities.
3093 [frontend-server] Added Attribute set to the bend_scanrequest API.
3095 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3096 surrogate diagnostics were generated.
3098 [retrieval] Allow multiple local values for attribute.
3100 [retrieval] Allow multiple attributes per element in .abs files. index type.
3102 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3104 --- 1.1pl2 1996/4/10
3106 Minor changes, mostly specific to Zebra's requirements (retrieval)
3110 Repaired bug in frontend server when running multiple listening
3111 endpoints in dynamic mode.
3113 z_External() now won't break if a known, ASN.1 value comes encapsulated
3114 in an octet-string. The value will pass through unmodified in an Odr_oct.
3116 Added a bit of code to the demo client to decode & display
3117 ASN.1-structured records represented in the octet-aligned branch of
3118 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3120 Added z_ext_getentbyref() to the ASN module. Doc updated.
3122 * Completed the SCAN definition in the ASN module. This may break SCAN
3123 code based on older YAZ-versions at compile-time. The fix is easy -
3126 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3127 under the SCAN definition. Remember to initialize this, server-people.
3129 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3130 that this does not extend to ODR and ASN.
3132 Comstack allows insertion of established socket (primarily for
3133 inetd-operation of servers). Doc updated.
3135 Front-end server can now start from the inetd in TCP mode. Doc
3138 --- 1.0pl4 1996/1/24
3142 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3143 the rank and record number.
3145 Adjustments to the frontend server.
3147 Fixed diagnostic BER dumper. It ignored the file argument.
3151 Various changes to retrieval module.
3153 Changed the union discriminators of the protocol files from enums to
3154 ints paired with #defines.
3156 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3159 *Changed operator in the RPN structure to 'roperator', again to avoid a
3162 Fixed problems in Explain decoders/encoders.
3164 --- 1.0pl2 1995/12/6
3166 Memory bug in log module fixed.
3168 --- 1.0pl1 1995/12/5
3170 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3172 Bug in Explain DatabaseInfo module fixed.
3174 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3178 The shift to v1.0 signals that we now consider the *core* functionality
3179 of YAZ reasonably stable (the core being more or less equivalent to
3180 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3181 tested (Explain not at all - though that will happen soonish).
3183 Minor changes to code to support Windows port.
3185 Various minor changes after we're getting to use GRS-1 & co. more.
3187 Added Espec-1 format.
3189 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3190 of the protocol and it cannot be selected when encoding (maps into 'string'
3191 when decoding). Needed to talk to some servers.
3193 Demo client can request simple element set names.
3195 Added Diagnostic Format encoders/decoders.
3197 Added simple Close handling to frontend server (no hooks for resource
3198 reporting yet), and demonstration client.
3200 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3202 --- 1.0b3 1995/08/24
3204 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3205 handled incorrectly when records were requested in the searchResponse. This
3206 will only affect you if you use the frontend-server.
3208 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3209 Test-client will ask for and print GRS1. Ztest will return dummy records
3212 Added Explain encoders/decoders to the service-level API. Untested.
3214 Added Extended Services: Item Order encoders and decoders to the Service-
3215 level API. Untested. We could use a recent copy of the pertinent bits
3216 of the ILL protocol to add those bits.
3218 Added diagnostic format 1 encoders/decoders to the service-level API.
3221 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3222 odr_cons.c, which causes a more correct output.
3224 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3225 was always set to 0 when no records were requested in the searchRequest.
3227 * Added better external-handling. This shouldn't harm old code that
3228 *encodes* externals. It can break code that looks for a
3229 'single-ASN1-type' representation, since those types that are known
3230 are now decoded immediately. Look at the SUTRS sample code in
3231 seshigh.c and client.c. Documentation updated.
3233 Handling of structured records in bend_fetchresponse. Length -1 marks
3234 structured record, type is deduced from format field.
3236 --- 1.0b2 1995/06/27
3237 Fairly quick maintenance release to add SUTRS support.
3239 Fixed handling of SUTRS records in the demonstration client.
3241 * Added format field to the bend_fetchrequest and bend_fetchresponce
3242 structures of the backend API (frontend server). When the record is
3243 returned, the value of the format field is mapped to an OID. The
3244 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3245 of the record. The special value VAL_NONE in the bend_request means
3246 that no specific format was requested by the client. Documentation
3247 updated accordingly. Test server (ztest) will return a fixed dummy
3248 SUTRS record if your client requests SUTRS.
3250 Documentation updated accordingly.
3252 You can now set external libraries and RANLIB support in the top-level
3256 First public release.
