3 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
4 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
5 redirect was used at the same time.
7 MARC line mode decoding: be less picky about length given - first
8 5 digits of header that is.
10 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
12 Changes to decoding of SRU records: a record with recordPacking=xml is
13 modified with a new root element <yaz_record> if the recordData contains
14 multiple children elements. This is to make the record XML parseable
17 RPN to SOLR conversion: encode special characters.
19 Generic Frontend Server: fix uinitialized member, stepSize.
23 Fix a bug in SRU decoding of records.. The database records stored
24 had un-initialized memory, but it would only be seen with yaz_record_render
27 Fix a bug in ccl_qual_dup introduced in 4.2.3.
31 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
35 Add new utilities to convert from CQL to CCL . These utilities have
36 prefix cql_to_ccl defined in cql.h.
38 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
39 lead to memory heap corruptions when ICU utilities were in use.
43 Make compilation work without Libxml2.
45 yaz-client: remove redundant blanks in display of searchResult-1 term
50 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
51 resulting CQL node (tree) in a new node CQL_NODE_SORT.
53 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
54 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
55 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
56 Note that the CQL sortby spec is only converted when the GFS is already
57 converting from CQL to RPN (cql2rpn element).
59 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
60 specify whether to collapse delimitors or not. The existing nmem_strsplit
61 do collapse (collapse parameter = 1).
63 Windows installer: For NSIS, set InstallDir depending on x86/x64.
65 Rename internal func yaz_use_attribute_create. While non-static, this
66 function is not declared in a public header.
70 Add -lCrun when linking with ICU on Solaris.
72 More quicks character set conversions for OPAC records.
76 fix problem with record_render: records were converted (character set
77 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
81 SRU: add methods for handling DADS SRU-proxy facets.
83 Separate OPAC record character set for ZOOM_record. yaz_record_render
84 allows a character set given as charset=from/opacfrom,to where 'from' is
85 the character set of a bibliographic record, 'opacfrom' is character set
86 of OPAC record and 'to' is the target character set.
90 yaz-client: show may XML format records. Command show followed by 'format'
91 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
94 src/stemmer.c: Avoid using unnamed union. It is not supported by some
97 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
100 Update yaz.spec to operate on both SLES11 / Centos 5.5.
102 RPM: Release includes 'indexdata' name. Use indexdata in release name so
103 this package can be distinguished from other vendors.
105 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
106 as determined by configure
108 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
110 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
111 returns no error and no record, the present request is considered
112 partial (only a subset of the records could be returned by backend), and
113 so it is appropriate to set Present Status to partial-4.
117 Move yaz-config man pages to section 1.
119 More documentation about SOLR.
121 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
122 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
123 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
124 peers on some Linux systems. However, in general that does not work
125 so YAZ can not rely on that to work. Debian changed behavior in this
126 respect from Debian lenny to Debian squeeze (still testing as of Oct
128 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
130 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
134 Fix yaz-config output: echo_source not set correctly by configure.
138 SOLR WebService support for yaz-client and ZOOM.
140 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
142 --- 4.0.12 2010/08/17
144 Z39.50 facet support. Facet specifications are passed for search in
145 other-information with ASN.1 as defined in facet.asn and OID
146 .10.1000.81.5 . Facets are expressed as an Attribute list as known
147 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
148 3 is limit (number of entries to get in response). yaz-ztest returns
149 dummy facets if a client asks for them.
151 --- 4.0.11 2010/07/09
153 CCL fixes: bug 2895 and bug 3539.
155 GR1-display: add comma in display - was removed by mistake in
158 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
160 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
162 --- 4.0.10 2010/06/18
164 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
165 result set from a connection. The result set will be on its own
166 thereafter; no operations on it will perform retrievals from a target.
167 Only cached copies are returned.
169 ZOOM C:fix case for HTTP servers responding with Connection:close.
170 Ensure that if there is a current task it is resumed (like fetching
171 more records in a result set) . Bug #3484.
173 PQF parser: use odr_atoi for Odr_int (not atoi)
175 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
176 values that contain any non-digits are treated as string attributes
177 (previously decoding only checked for leading character ([0-9]). PQF
178 encoding: attribute string values are not surrounded by double-quotes.
182 New utility for managing threads - thread_create.h.
184 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
185 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
186 but YAZ' implementation do.
188 Fixes for yaz_cond-functions on Windows 7.
190 DLL export more symbols.
192 zoomsh: show record do NOT render opac.
194 Remove *.la files from Debian and RPM packages.
198 Debian package libyaz-dev depends on libgnutls-dev again (was
199 removed in YAZ 4.0.6, but due to Libtool it is still needed
200 even though yaz-config do not list libgnutls libs).
202 ZOOM: Use only one WRBUF for returning string results for
203 ZOOM_resultset. Reduces memory usage for ZOOM in general.
205 ZOOM: ZOOM_connection do not use a shared pointer to
206 ZOOM_resultset after ZOOM_resultset is destructed by
207 user. Reverts to YAZ 4.0.4 behavior.
211 record-conv: fix problem with at least one XSL conversion -
212 due to probably incorrect usage of XML XSL documents.
216 Fix yaz-config for static mode and the use of SSL (gnutls).
220 Forward decl timeval struct in mutex.h and gettimeofday.h.
222 yaz-config: fix 'static' mode linking.
226 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
227 are wrappers for pthreads or Windows. For Windows these are put in
228 a separate DLL: yaz_cond4.
230 libyaz.la (whole source) is compiled with thread. If thread support
231 is enabled enabled, all source of YAZ is compiled with treading support.
232 This allows core utilities such as yaz_log to use thread facilities.
233 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
234 thread utilities. This commit moves mutex utilities (mutex.c) from
235 libyaz_server.la to libyaz.la.
237 yaz-json-parse displays leading text until error.
241 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
242 patch from Giannis Kosmas.
244 SRU: no longer URL encode SRU database. The URL for an SRU server is
245 a URL and such is alreeady encoded - at least when given with leading
246 http:// or https://. This reverts behavior to YAZ 3.0.50.
248 Support for new MARC XML notation TurboMARC which like MARCXML is a
249 complete representation of MARC/ISO2709.. This one, however, is more
250 compact and allows for faster processing with XSLT. TurboMARC can be
251 used in the marcdisp.h API, from the yaz-marcdump utility and from
254 yaz-ztest can be configured - via the database - to perform certain
255 delays when it performs operations search, present and single record
256 fetch. This allows testers to make yaz-ztest act as a real or even slow
257 Z39.50 server. Refer to the yaz-ztest man pages for details.
261 wrbuf_destroy allows NULL WRBUF passed to it.
263 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
265 Add ZOOM_connection_close.
267 No fixed size buffers for ZOOM shell - bug #3257.
269 tstodr: make it work on s390 platform.
271 New icu iterator-functions. The new icu_iter-functions makes it possible
272 to use ICU chains from many threads.
274 yaz-client: better syntax check for show command.
278 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
281 New simple local-file XML include facility which allows file glob-patterns.
282 Refer to yaz/xml_include.h.
284 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
287 ZOOM_record_get supports new parameter "format" which makes it format XML
290 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
291 JSONText in ECMA-262) is JSONValue, not JSONObject.
295 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
296 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
298 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
299 POSIX/Unix builds .so with major version 4.
301 Remove old LOG_-defines from log.h. They have been obsolete and
302 undefined by default for the last 5 years.
304 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
306 GFS: Remove socket (int *fd) from search_rr handler. The socket
307 descriptor ptr is a facility that allowed a search handler to supply
308 a socket which would serve as a callback - when search was complete.
309 This facility has now been in use for years.
311 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
312 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
313 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
314 returns 'const char *' rather than 'char *. The returned string is
315 read-only and should not be modified by applications. COMSTACK cs_close is
316 now a void function - it no longer returns int. No applications check for
317 the value and the implementations has always returned 0.
319 ZOOM: use size_t for scan hit counts and str size. Functions
320 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
321 occ (hit count) and len (string length) are now of type size_t pointer
322 rather than int pointer. This is to be able to represent large hit counts
323 and to also just to use the proper type for string length (strlen result).
325 New JSON parser. Refer to include/yaz/json.h .
327 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
328 Used to be int in some cases. Many wrbuf_-functions used to return an int
329 indicating some length.. These return values were never used. And so they
332 ODR: odr_malloc, odr_total now takes size_t for size.
334 clone_z_type: fix leak; occurred for encoding failures.
336 --- 3.0.52 2009/12/03
338 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
339 bug was introduced in 3.0.51.
341 --- 3.0.51 2009/12/02
343 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
345 tcpip comstack: fix leak for getaddrinfo.
347 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
348 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
349 Decoding of SRU "path" database is performed by private function
350 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
351 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
353 yaz-client: honor base command for SRU. Change when database setting
354 is applied for SRU and ensure it is kept when a connection is reset.
355 Change also the way errors are displayed or SRU (decoding of packages).
357 --- 3.0.50 2009/11/02
359 Add support for extra request / response data for SRU codecs and GFS.
360 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
361 for extra data response buffer and length. For the GFS, both request
362 and response data (XML) is carried in extra_args and extra_response_data
363 for the search handler. Patch by Ko van der Sloot.
365 ZOOM: For queries that cannot be converted to the specified rpnCharset,
366 ZOOM now returns a diagnostic on the client-side ('invalid query' /
367 10010). This fixes bug #2113.
369 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
370 cmdfile included a 'quit' command that would result in a memory violation.
372 --- 3.0.49 2009/10/01
374 Make a number of functions defined in xmlquery.c static. These have
375 never been declared in a public header file (yaz/xmlquery.h) and was
376 made public by mistake.
378 Improve speed of character conversions (iconv utilities). This makes
379 conversions from MARC-8 faster.
381 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
382 unless type desired is "raw". This will prevent type "xml" from
383 returning ISO2709 .. Which obviously can not be XML parsed.
385 Fix memory leak in ZOOM that would occur if option apdulog was used
386 on a re-used connection.
388 Frontend server logs HTTP requests.
390 Frontend server now sends Z39.50 close when it times out (sesssion has
391 been idle for too long). Versions 2.0.30 and earlier also sent close.
392 But due to a mistake this was disabled in all versions after that, i.e.
393 the server would just close the socket immediately.
395 yaz-client emits a better message when receiving an unrecognised
396 userInformationField.
398 Skip zero-length subfields when decoding ISO2709. This rare case happens
399 if a record has two FS characters in a sequence. Without this patch
400 there would be a reference beyond char array in using_code_len fragments
403 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
405 --- 3.0.48 2009/08/28
407 The show command offered by the zoomsh command now takes a 3d optional
408 parameter type which is what is passed to ZOOM_record. If the type
409 argument is omitted, "render" is used.
411 RPN to CQL conv may use USE string attributes (bug #2978).
413 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
415 --- 3.0.47 2009/07/08
417 Function yaz_xml2query allows a diagnostic element in the PQF XML
418 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
419 code and additional info respectively.
421 The BER BOOLEAN is now the integral type Odr_bool which still happens
422 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
423 typedef'd to Odr_int. This is still an integral 'int', but it may be
424 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
425 ASN-1 compiler as well as programs has been updated to use the new types.
427 --- 3.0.46 2009/06/08
429 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
430 only the bibliographic record was rendered. For type=opac, an OPAC
431 record is only returned if it is present.
433 iconv: small fix for encoding of advancegreek.
435 yaz-client: avoid double display of SRU/SRW records (bug #2798).
437 yaz-client: option auto_reconnect=on really reconnects.
439 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
441 server: avoid null ptr ref for for yaz_poll errors.
443 build: fix RPM build for RHEL 5.3.
445 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
447 --- 3.0.45 2009/03/31
449 Fixed bug #2709: TCP connect returns Invalid argument.
451 Fixed compilation for mingw.
453 Honor charset for raw records (ZOOM_record_get).
455 Fixed use of errno for threaded mode that was seen on Solaris 10.
457 Fixed argument passing with blanks in value for Windows Service.
459 Disable YAZ' own log rotate by default (no 1 GB limit).
460 The variable l_max_size which specifies the log file limit is set to 0
461 (DISABLED): This is due to the fact that YAZ is most often deployed using
462 logrotate. Also YAZ can not perform log rotate because of unsufficient
463 permissions (setuid).
465 --- 3.0.44 2009/02/17
467 List supported encodings in man page for yaz-iconv.
469 Fixed missing SSL libs for --libs output
471 Re-established OID record syntax application-xml. Nobody should use it
472 but we don't want to change soname because of this symbol being absent.
474 --- 3.0.42 2009/02/02
476 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
478 Added member named_result_sets for init handler struct for the GFS. This
479 allows a server to disable named result sets.
481 Removed OID record syntax application-xml.
483 Added support for rule-based transliterator for ICU wrapper of YAZ.
485 Fixed bug #1902: yaz-icu XML output.
487 Make YAZ checks Emacs friendly.
489 BITSTRING value shows value. Bug #2346.
491 ISO2709 decoding: skip control characters from indicator data.
493 Omit sort key by default in yaz-icu's output.
495 Allow combined single char options (again) for YAZ' options function.
497 Utility yaz-marcdump got option to display YAZ version (-V).
499 Allow YAZ to use ICU 3.4.
501 Added new ICU test case which illustrates removal of diacritics.
503 --- 3.0.41 2008/12/29
505 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
507 --- 3.0.40 2008/12/29
509 For configure, using option --without-xml2 also disables Libxslt/Libexslt
512 Fixed bug #2352: yaz-marcdump crashes for certain record.
514 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
516 Added support for Danmarc2 to UTF-8 conversion.
518 Added support for ISO5426 to UTF-8 conversion.
520 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
521 implementation version.
523 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
525 --- 3.0.38 2008/11/10
527 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
528 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
530 ZOOM C now interprets databaseName option for ZOOM connection as path
533 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
535 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
537 Dummy Libxml2 types no longer defined in headers of YAZ'.
539 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
542 --- 3.0.36 2008/09/26
544 Various ODR chapter fixes.
546 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
548 Added missing source for Windows compilation, mutex.c.
550 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
552 For SRU connections in ZOOM all records up to "count" are now fetched.
554 Fixed crash in generic frontend server (and yaz-ztest) which occurred
555 in Windows due to bad error handling for Libxml2.
557 Added facility for sending arbitrary records (ASN.1 any) using
558 ZOOM C's Extended service update. Patch by Sam Reynolds.
560 New options for ZOOM C's connection, logapdu which makes ZOOM log
563 --- 3.0.34 2008/06/18
565 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
567 --- 3.0.32 2008/06/12
569 Fixed memory violation that could occur when decoding UTF-8. This bug
570 was only present in 3.0.30 of YAZ.
572 --- 3.0.30 2008/06/06
574 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
575 GNU TLS is used by default (if found).
577 yaz-ztest returns OPAC records if a client asks for OPAC.
579 Improved speed of MARC-8 encoding.
581 Added support for lossy and loss-less MARC-8 encoding.
583 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
585 Added new Windows Service wrapper (sc).
587 yaz-client's itemorder command may now send a file.
589 Fixed yaz-marcdump to allow the use of NS prefix for record element.
591 Added new function yaz_log_xml_errors.
593 Allow (but warn) unknown XML attributes in MARCXML parsing.
595 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
597 The UTF-8 to MARC-8 conversion now uses a different set of characters
598 for Greek symbols. Bug #2120.
600 --- 3.0.26 2008/02/21
602 Added yaz_daemon (daemon.h).
604 Fixed bug #2068: pkg-config trouble
606 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
608 --- 3.0.24 2008/01/28
610 Document --with-xml2 option.
612 Added OPAC XML XSD (etc/opacxml.xsd).
614 Allow glob mask for name attribute in retrieval element for the
615 generic frontend server's retrieval facility.
617 Changed yaz_poll_poll to return yaz_poll_except for all returned events
618 except POLLIN/POLLOUT.
620 Fixed error handling in cs_listen. Bug #2037.
622 --- 3.0.22 2008/01/20
624 Fixed version in yaz/yaz-version.h.
626 Fixed bug #2027: Crash when closing connection.
628 Changed configure so that ICU support is only enabled if only ICU
629 and Libxml2 is available (because the ICU chain is XML based).
631 --- 3.0.20 2008/01/15
633 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
634 is built. Only this DLL depends on the ICU runtime.
636 yaz-ziffy is no longer part of YAZ. It is distributed separately by
637 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
639 Changed license of CCL module to 'Revised BSD'. After consultation with
640 remaining members of the original EUROPAGATE consortium, we are re-issuing
641 the CCL module without a separate license. The software was developed by
642 Index Data as part of a research project. The special license was included
643 to help feed usage information back to the project consortium to support
644 project evaluation. At this time, the project consortium has long-since
645 disbanded, and the majority of the original principals have retired. At the
646 same time, we have significantly modified the software during the following
647 years, to the point where very practically no original code remains. To
648 simplify re-use of the software, we have contacted those members of the
649 consortium who could be reached, and agreed to re-issue the module as a
650 proper part of the YAZ package.
652 Tcl scripts uses /usr/bin/tclsh as preferred shell.
654 CQL closer to being version 1.2 compliant. CQL also allows free-form
655 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
658 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
659 bug could make Extended services handling crash in the ZOOM layer. This
660 bug was only present in YAZ 3.0.18.
662 --- 3.0.18 2007/12/19
664 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
667 yaz-marcdump reads and writes collection wrapped records.
669 Handle OPAC for record conversion module.
671 Fixes for ICU wrapper.
673 Allow ICU libs to be controlled with --with-icu .
675 --- 3.0.16 2007/11/12
677 Added yaz_poll which is a wrapper for select/poll. When poll is available
678 and non-buggy, it is used, by yaz_poll . This allows more than 1024
679 sockets to be in use.
681 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
682 functionality through an XML based configuration (ICU chain). This system
683 is useful for search facilities such as Pazpar2 and Zebra that needs to
684 perform tokenization of indexed material. The ICU code in a separate
685 library libyaz3_icu.a.
687 Added HTTP tunnel facility for COMSTACK, bug #1752.
688 This is a facility that allows a Web proxy, such as squid, to tunnel
689 Z39.50 traffic. This facility is "transparent" to must applications
690 using YAZ. It's enabled by using pseudo transport connect: followed by
691 the proxy address, followed by command, then follwed by he regular
692 "virtual" addresss. For example,
693 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
695 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
697 --- 3.0.14 2007/09/21
699 Fixed bad memory reference in ZOOM_record - cuased by member not being
700 initialized. This was a problem only in YAZ 3.0.12.
702 Fixed bug in conversion from MARC to XML: Non-XML characters in control
703 fields were not removed.
705 Changed the way C code is generated from codetables.xml. Made a MARC-8
706 conversion trie for each characterSet section rather than codeTable.
707 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
708 of codetables.xml from Larry Dixson, LOC. Bug #1464.
710 --- 3.0.12 2007/09/12
712 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
713 from ZOOM_record_error).
715 ZOOM C function ZOOM_record_get returns record schema for type="schema".
717 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
719 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
721 Better SRW-to-Bib-1 diagnostic mapping.
723 ZOOM C and yaz-client announces SRU version 1.2 by default.
725 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
728 Fixed in yaz_sru_decode to allow other version than 1.1.
730 --- 3.0.10 2007/08/22
732 Added support for SRU scan for ZOOM.
734 Added support for the use of the older versions or Extended Service
735 Update in ZOOM. To faciliate this, an option "updateVersion" may be
736 set to the version , 1=first, 2=second, 3=third. The third version is
737 what ZOOM C has used so far. And that, obviously, is the default.
739 Added support for CCL queries in Z39.50 queries sent to the GFS (and
740 therefore in Zebra and in SimpleServer-based applications). The new
741 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
742 qualifier file used to transform incoming CCL queries into Type-1 RPN,
743 which is passed into the back-end search callback function.
745 Added support for HTTP Basic authentication in clients: the SRU/W
746 codec encodes the username/password elements of the PDU structure
747 appropriately, and these may be set using the "user" and "password"
748 options in ZOOM-C applications (the same options that are used for
749 Z39.50 authentication).
753 Fixed bug #1208: SSL appears to be broken in ZOOM.
755 Fixed bug #1206: Libxml2 include path weirdness.
757 Added oid_name_to_dotstring.
759 Allow elementSetName to be specified for ZOOM C record update.
761 Allow waitAction to be specified for ZOOM C based for Extended Services.
763 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
764 syntax OID. Bug introduced in YAZ 3 series.
766 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
770 Fixed bug #1157: yaz-client does not read .yazclientrc from current
771 directory. yaz-client now reads commands from file given by option -f
772 if specified; then tries to read .yazclientrc in current directory.
773 Failing that, it reads .yazclientrc from user's home directory.
775 Added support for correlationInfo Note and ID for Record Update via
778 Added yaz-client command querycharset which specifies character set for
779 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
780 (termListAndStartPoint).
782 Charset ISO5428:1984 is an alias for ISO5428-1984.
784 Implemented a way to perform scan in a result set using Z39.50. This
785 is achieved by attaching the result set name in the characterInfo
786 (type InternationalString) of OtherInformation in the Scan Request PDU.
787 The result set is identified in the otherinformation by the new OID:
788 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
789 This allows for scan in result set and faceted search . Zebra did some
790 of this in the APT term using attribute type 8 and value being result
791 set. Using the OtherInformation approach for this is cleaner and easier
792 to work with in proxies and the like. This facility can be used in
793 yaz-client using new command setscan which takes a result set as first
794 argument, start position (APT) as second.
796 Changed decoding of SRU XML packed records to deal with servers that
797 have recordData with XML data with multiple root nodes. Also make
798 comparison for recordPacking case insensitive. Again, one server
799 returns "XML" where others return "xml".
801 For SRU responses allow Content-Type application/xml as well as text/xml.
805 Fixed bug in character set conversion of BER strings. Bug introduced
810 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
812 For OID class, use oid_class consistently.
814 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
817 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
818 character set for bibliographic information interchange". By Giannis Kosmas.
820 Added documentation on new OID API.
824 Changes to generic frontend server interface: added new member
825 'query_charset' for bend_initrequest structure. A backend init handler
826 should set this member to its native character set for query terms.
827 When defined, the frontend server logic will announce this character set
828 to a client if the negotiationModel bit is set by the client. All server
829 implementors are encouraged to specify this. If a backend server does not
830 specify this a warning is issued using yaz_log(YLOG_WARN,..).
832 Added CCL utility to remove terms (stop words) from resulting RPN
833 tree. This is handled by functions with prefix ccl_stop_words_ .
835 New ZOOM C option, "rpnCharset", which allows client-side conversion of
836 terms in RPN queries.
838 Clean-up the CCL API. Moved some internal structures from ccl.h to
839 private header cclp.h. Changed ccl_parser_create so that a Bibset must
840 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
841 This is replaced by ccl_parser_find_str which takes a string instead.
843 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
844 libyaz.la is the core of YAZ except the generic frontend server and
845 does not depend on POSIX threads anymore. libyaz_server.la is the
846 generic frontend server facilities and uses POSIX thread functionality
847 if available. The libyaz.la no longer depends on POSIX threads because
848 the number of global structures is limited. NMEM no longer re-uses blocks
849 between threads ; it simply free's memory immediately but allocates in
850 "large" chunks as usual. We don't expect any performance penalties
851 because of this. The yaz_log system is still using a global log_level so
852 caution must be taken when modifying it with yaz_log_init_.. +
853 yaz_log_mask_str. This, however, should not cause any trouble because
854 these functions are called during initialization of application code
855 anyway. `yaz-config --libs server` returns libs for server applications;
856 `yaz-config --libs` returns libs for non-server applications.
858 New OID database - with public definitions in oid_db.h. Removed old OID
859 database including the head oid.h and definitions such as enum oid_value
860 and struct oident. The new OID database uses the same string names as
861 before but the 'protocol' is gone. There are now only two representations
862 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
863 converts from string to OID; functions with prefix yaz_oid_to_string
864 converts the other way.
866 Change to emit_term() in CQL-to-PQF query translation: when a term has
867 the /regexp relation modifier, do not process it for leading and
868 trailing "^" and "*", which have quite different meanings in regular
871 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
872 write handlers no longer carries a 'last' parameter. This will make
873 yaz_iconv flush "less" characters. A flush is performed by call to
874 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
876 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
877 removed, because function yaz_query_to_wrbuf does the same.
879 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
880 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
882 Deprecated MARC utility functions removed.
884 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
887 Branch split: YAZ_2_1_55_branch
889 --- 2.1.54 2007/03/16
891 Fix to ZOOM-C so that transparent reconnection is properly handled on
892 connections that are in asynchronous mode.
894 Fixed compilation on OpenBSD 4.0.
896 Large strings in GRS-1 records are now properly displayed in yaz-client.
898 Added character conversion support for "advancegreek"; based on patch from
901 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
902 sequence is met. Before the error was not set so it would be unknown.
904 Adjust yaz-marcdump MARC reader so that it skips until record separator
907 --- 2.1.52 2007/03/07
909 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
910 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
911 fd_set structure used as a bitmask for the FDs to be selected on.
913 Using ACX_PTHREAD macro to check for POSIX threads.
915 Fixed have-vsnprintf check.
917 --- 2.1.50 2007/02/23
919 Fixes for configure on BSD. Bug #900.
921 Added snprintf/vsnprintf wrappers for systems that don't have
922 limits (heavens forbid).
924 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
925 created before all previous tasks were completed and removed from the
926 task queue, the new task could be removed by a mistake.
928 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
930 Implemented pass-through CQL-to-PQF conversions. Bug #861.
932 Fixed bug #832: Problem with MARC/charset in yaz-client.
934 Fixed bug #668: save command line history for yaz-client.
936 Fixed bug #830: pkg-config support.
938 --- 2.1.48 2007/01/23
940 Extended ZOOM result set options with two options that may be read by
941 a client: resultSetStatus and presentStatus with values as specified for
943 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
945 Fixed bug #827: Using SSL fails on Debian etch.
947 Fixed bug #826: Weird looking chars for set of MARC records.
949 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
950 that is treated as an ItemOrder with itemRequest being an XML document
951 external. The value of "doc" is the content.
953 Extended the GFS search facility. New member of bend_search_rr
954 'estimated_hit_count' signals that hits is known to be an estmate
955 (higher or lower than real hit count). New member 'partial_resultset'
956 signals that the search was partial (hit count is lower or equal than
957 real hit count). For Z39.50, the information is stored in resultSetStatus
958 member of SearchResponse APDU. For SRU, the information is signalled
959 via SRU diagnostic 59: "Result set created with valid partial results
962 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
964 --- 2.1.46 2007/01/13
966 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
968 Added ZOOM_connection_peek_event.
970 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
971 the following new functions:
972 ZOOM_event_nonblock, ZOOM_connection_process,
973 ZOOM_connection_get_{socket,mask,timeout},
974 ZOOM_connection_fire_event_{timeout,socket}.
975 The existing blocking event handler, ZOOM_event, is a wrapper for the
976 + blocking ZOOM_event_sys_{poll,select}.
978 Implemented function ccl_xml_config which parses XML version of CCL
979 configuration (bug #798).
981 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
983 Added timings utility (yaz/timing.h)
985 --- 2.1.44 2007/01/03
987 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
990 Fixed bug #779: Rotation of apdu.log fails.
992 Fixed for character set conversions:
993 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
994 Honor G1 set in MARC-8 decoding.
996 --- 2.1.42 2006/12/17
998 Fixed bug #775: char conversion does not handle Alternative UTF-8
1001 Implemented function yaz_marc_read_line which parses MARC line format
1002 records. There is a wealth of formats out there. So far, this function
1003 reads line records produced by yaz_marc_write_line.
1005 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1006 more generic and easier to remember(!) options: -i format and -o format
1007 which specifies input format and output format respectively - where
1008 format is one of "marc", "marcxml", "line", "marcxchange".
1010 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1011 does not print anything except warnings for records.
1013 For yaz-marcdump, added support for MARC split into files (-s) with a given
1016 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1017 spec, at http://www.loc.gov/standards/sru/record-update/
1018 This has changed the binary layout of the following structs:
1019 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1020 bend_update_rr . Patch by Ko van der Sloot.
1022 Added GFS utility function bend_assoc_is_alive which returns 1 if
1023 association is still alive (client is connected); 0 otherwise (client
1024 closed connection). This allows busy servers to stop working for
1027 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1028 been a separate piece of software. This version of ziffy has been modified
1029 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1031 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1033 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1034 Client code may now interrogate options such as "init_opt_sort" to
1035 find out whether the server claims to support various options.
1037 --- 2.1.40 2006/11/27
1039 Added utilities yaz_{set,get}_esn to set/get element set name from
1042 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1043 of YAZ and has been so since YAZ 2.1.10.
1045 Implemented ZOOM_record_error which returns error information for
1046 record (surrogate diagnostic).
1048 --- 2.1.38 2006/10/31
1050 Updates for SRU Update by Ko van der Sloot:
1051 1. Changed name from "operation" to "action"
1052 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1053 versions in the code, marked as 'backward compatible'.
1054 3. Added diagnostics for SRU Update.
1056 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1058 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1060 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1062 For GFS, fixed problem with SRU diagnostic 'First record position out of
1063 range' being issued for 0 hits.
1065 zoomtst10 part of Windows Build.
1067 --- 2.1.36 2006/10/13
1069 Implemented yaz_filepath_comp which splits a path into file path
1070 components (required by Zebra 2.0.3+).
1072 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1073 BSD inspired license until now so this should not have any real impact on
1074 anybody. See http://www.opensource.org/licenses/bsd-license.php
1076 Fixed bug #687: Missing log lines.
1078 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1081 Fixed bug #689: SRU diagnostics to be added.
1083 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1084 whether a connection is idle (no more work do do).
1086 --- 2.1.34 2006/10/04
1088 Change type of optval from long to int for invocation of setsockopt with
1089 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1091 Added support for specifying the max log file size for the Generic
1092 Frontend Server. The size is given with option -r.
1094 --- 2.1.32 2006/09/21
1096 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1098 --- 2.1.30 2006/09/17
1100 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1103 Fixed bug in Generic Frontend Server that could cause a server to stop
1104 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1106 For the generic frontend server, the maximum record size is used as maximum
1107 size of incoming packages (SRU + Z39.50). The value until was previously
1108 only used in Z39.50 Init negotiation and, later, in a session controlled
1109 sizes of records returned. This is controlled using -k option. It can be
1110 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1112 --- 2.1.28 2006/09/04
1114 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1117 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1119 New option for yaz-marcdump -lpos=value which allows setting a portion
1120 of MARC header to a certain value.
1122 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1124 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1125 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1127 --- 2.1.26 2006/08/15
1129 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1132 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1134 --- 2.1.24 2006/08/08
1136 Fixed MARC ISO2709 encoding routines to deal with character set
1139 Minor changes to GFS logging. Database included in search request log
1142 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1143 cached/multiple records.
1145 Shared libraries are built by default on Unix+configure.
1147 Changed cql2pqf transformation to use a different evaluation order. The
1148 new order is: always, relation, structure, position, truncation, index
1149 and relationModifier. Old order was: always, relation, relationModifier,
1150 structure, index, position, truncation. Note that the the latter ones
1151 override former ones for identical attributes.. The new scheme means that
1152 it is possible to override any existing attribute with a relationModifier.
1153 And also that it is possible to override everything for the index rule
1154 (except the ones listed in relationModifier). No order is perfect but this
1155 one, we believe, covers more real cases.. The "always" should have been
1156 called "default", since the attributes there can be overridden with all
1159 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1160 compilation phase, but also for yaz-config --cflags output. This allows
1161 us to have public headers with Libxml2 stuff in them . It should also,
1162 eventually, make Libxml2 checks redundant in packages using YAZ, such
1165 --- 2.1.22 2006/06/15
1167 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1168 stored in uri, message and details.. Previously diagnostics were stored
1169 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1170 compatibility.. but he's probably the only one affected, so.
1172 Added support for CCL, compiled on the client side, in ZOOM-C. This
1173 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1174 input; the resulting query objects can be used for for searching with
1175 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1177 YAZ' configure searches for OpenSSL by default.
1179 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1180 SL_CTX_use_certificate_file. See
1181 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1182 for more info. Thanks to Ko van der Sloot.
1184 --- 2.1.20 2006/06/02
1186 Bug #600: SRU GET, POST support for yaz-client. Introduced
1187 command 'sru' which selects method SOAP/GET/POST.
1189 Allow missingValueAction to be specified for the sortspec string -
1190 function yaz_sort_spec. By default, the missing value action is null.
1191 Use ! to specify "abort". Use = followed by stringvalue to specify default
1194 Ensured that Present-handler (if defined) is called in GFS before any call to
1195 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1196 searchRetrieve requests.
1198 Documentation for YAZ is now based on the Docbook XML/XSLT using
1199 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1200 is no longer depending on jade/openjade or docbook-to-man scripts.
1201 PDF is no longer part of the distribution - but can optionally be
1202 made using DSSSL/jadetex or FOP.
1204 Added retrieval handling support in Generic Frontend Server to support
1205 conversion between MARC/XML as well as XSLTtransforms. See
1206 etc/yazgfs.xml for an example.
1208 Added Authentication support to Generic Frontend Server in SRU
1209 mode. Authentication using HTTP Basic is supported, as is the use
1210 of 'x-username' and 'x-password' parameters in the request itself.
1212 Added support for a new character set MARC8s identical to MARC8 except
1213 that it converts combined characters to single Unicode characters in the
1214 Latin-1 range (when possible).
1216 --- 2.1.18 2006/04/24
1218 ASN.1 compiler 0.4: generates brief Doxygen file header for
1219 generated .h/.c files.
1221 Utility yaz_iconv now supports conversion to MARC-8.
1223 New facilities for the MARC module. The reading - and writing of
1224 content are separate methods for the yaz_marc_t handle. The following
1225 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1226 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1227 format). Write functions have prefix yaz_marc_write_.. The existing
1228 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1229 available. Removed support for OAI-MARC and simplexml (not the
1230 simplexml from PHP5).
1232 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1233 to be returned for this connection.
1235 --- 2.1.16 2006/03/31
1237 Allow multiple languages and charsets to be specified with
1238 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1239 negcharset iso-8859-1,utf-8
1241 Translation of proximity nodes from CQL into PQF now works.
1243 Moved to automake 1.8, 1.9.
1245 Added function yaz_log_set_handler which allows a log handler to be
1246 installed. This handler will be called for all log messages. Output
1247 to file is also produced; but that can be disabled by passing NULL
1248 fname to yaz_log_init_file.
1250 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1252 For SRW (including GFS), accept application/soap+xml as content-type
1255 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1256 produces NO stylesheet reference even if a default stylesheet is specified
1259 --- 2.1.14 2006/03/14
1261 Updated Windows package to include yazd.dll + yazd.lib for the
1262 Development component.
1264 If the environment variable YAZ_LOG is set, then it is used as a
1265 string indicating the default level of logging to use if not
1266 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1267 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1268 used as before. So, for example, to omit warnings from YAZ logging,
1269 export YAZ_LOG=-warn
1271 cql_transform() now map structure and other attributes before indexes,
1272 so that index-specific structures and other attributes can override
1273 defaults. So now a combination of mapping specifications such as:
1275 index.dc.date = 1=date-modified 4=5
1276 does the right thing.
1278 cql_transform() now also respects the "always" mapping specification,
1279 which establishes an initial set of attributes to be used for all
1280 terms except where overridden by more specific attributes associated
1281 with the index, relation or modifier.
1283 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1284 which mode to use; one of "post", "get" or "soap" (SRW, default).
1286 Fixes for yaz_iconv routines: changed trie-based character set conversions
1287 to use only non-negative values for bit fields due to Sun's C compiler not
1288 supporting negative values.
1290 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1291 sequences where not read correctly. Fix by Rustam Usmanov.
1293 Updated win/makefile to use options, settings which makes things
1294 compile with VS C 2005.
1296 --- 2.1.12 2006/02/01
1298 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1300 In ZOOM socket code, use select instead of poll on MacOSX.
1302 ZOOM-C now support client-side compilation of CQL into RPN that is
1303 sent to the server, enabling CQL to be used against all Z39.50
1304 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1305 ZOOM_query object, and submit it using ZOOM_connection_search().
1306 The CQL-to-RPN translation uses a configuration file, the name of
1307 which must be specified in the Connection's "cqlfile" option.
1309 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1310 function, which takes as its start-term parameter a ZOOM_query object
1311 (which may have had either CQL or RPN set into it).
1314 --- 2.1.10 2005/11/29
1316 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1317 GFS to support this as well. Backend handler, bend_srw_update, does the
1318 update work. Code contributed by Ko van der Sloot.
1320 Allow retrieval of Search Result-1 information in ZOOM by the use of
1321 options that are attached to a result set. ZOOM documentation updated
1324 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1325 UTF-8 conversion. Patch by Raj Patel.
1327 Added option -m to GFS to control formatting of timestamps in log file.
1329 Added 'exit' as synonym for 'quit' in yaz-client
1331 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1332 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1333 for the new members. Patch by Ko van der Sloot.
1335 Added support for SRU POST. It is supported for content-type
1336 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1338 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1339 Instead make the library libyaz.la multi-threaded. Threading as a whole
1340 can still be disabled by configure option --disable-threads. Previosly,
1341 with older GLIBCs there were problems with MT libs under Apache. This
1342 has now been fixed a long time ago.
1344 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1347 CQL module modified to be case insensitive for relations/indexes/operations.
1349 Fixed bug in CQL transform code: incorrect value relationModifieder
1352 Added 'show all' command for yaz-client which retrieves all results
1355 Added new yaz-client, xmles, which takes a (private) OID and
1356 a document to be sent as an extended service request.
1358 Describe new yaz-client commands wait_response and set_auto_wait.
1360 Increase TCP/IP listener backlog from 3 (which I am guessing was
1361 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1362 that the socket will queue as many incoming connections as it's able
1363 to handle ongoing connections. In other words, it will never now
1364 refuse a connection that it would be able to handle merely because
1365 it's not got around to accepting() enough of the pending connections
1366 yet. This is the behaviour anyway under Linux, where the listen()
1367 argument is ignored; but not under BSD and on systems such as
1368 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1369 YAZ-based servers should now be uniform across operating systems in
1372 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1373 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1374 This allows yaz-marcdump to read large MARC batches (>2 GB).
1376 Modified all YAZ source files - except the source which is auto-generated
1377 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1380 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1381 corresponding to the existing *_setl() function. These allow option
1382 values containing arbitrary valuues.
1384 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1385 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1386 except that it returns an indicator of whether or not the sort
1387 criterion was accepted (0 for OK, -1 for invalid).
1389 --- 2.1.8 2005/06/07
1391 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1392 MARC output rather than returning "new" buffer.
1394 yaz-client warns about unknown init options.
1396 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1398 --- 2.1.6 2005/05/24
1400 Added support for SRW sort in Generic Frontend Server. Patch
1401 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1402 sortKeys - or NULL if none is provided.
1404 Fixed bug #307: It was impossible to specify indefinite/no timeout
1405 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1408 Added support for multiple languages and charsets to be specified in
1409 ZOOM. Each charset/language is separated by a blank. If negotiation is
1410 in effect in init-response, Option
1411 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1412 Code based on patch by Vasiliy Osadchuk.
1414 Fixed bug #306: infinite recursion that occurred when calling
1415 yaz_log_level_init as the first call (before other log level or
1418 Fixed bug in scan handling in front end server: if preferred-Position-In-
1419 Response was non-present, a NULL pointer referece was performed.
1421 --- 2.1.4 2005/04/26
1423 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1424 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1425 now defined for all those error codes. So instead of putting 109 in
1426 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1427 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1429 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1432 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1434 Program yaz-client now exits and produces an error message if multiple
1435 Z39.50 servers are specified on the command line (none or one allowed
1438 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1441 --- 2.1.2 2005/03/16
1443 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1445 Fixed bug #272: Preserve spacing for CCL terms.
1447 --- 2.1.0 2005/03/14
1449 Added support for virtual hosts and multiple backend servers for
1450 the YAZ frontend server. The configution is XML based and
1451 support specificition of CQL to RPN mappings and explain information.
1452 See section "Virtual Hosts" in the YAZ manual.
1454 Extended OPAC display utility. OPAC display utility renders
1455 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1456 to supplement yaz_marc_decode_wrbuf.
1458 Fixed a bug in MARC decoder that could caused it to crash for some
1459 invalid MARC records. More diagnostics and warnings where added in
1460 XML output (warnings, etc are stored in comments).
1462 --- 2.0.34 2005/02/08
1464 Fixes for UNIX domain sockets. Bug #261.
1466 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1468 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1469 Added yaz_marc_subfield_str which defines subfield lead string which is
1470 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1471 yaz_marc_endline_str which defines end of fields string used in
1472 YAZ_MARC_LINE format. Default string is newline.
1474 Experimental support for MarcXChange. This format can be produced
1475 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1476 http://www.bs.dk/standards/MarcXchange.xsd
1478 Added yaz-client commands scansize that sets maximum number of
1479 entries to be returned by scan.
1481 --- 2.0.32 2005/01/11
1483 Added support for SRW scan in yaz-client and Generic Frontend Server.
1485 * Added whereInList member to SRW Scan Term.
1487 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1489 Fixed NMEM system to return aligned blocks on the smallest boundaries
1490 that are suitably aligned for all possible types on the particular
1491 architecture YAZ is being built for.
1493 --- 2.0.30 2005/01/04
1495 Fixed numerious warnings that was issued with newer versions of GCC.
1497 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1498 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1501 Make YAZ Generic Frontend Server slightly faster.
1503 Enhance (and reduce) logging for Generic Frontend Server.
1505 Revert YAZ log system so that it flushes every write operation
1506 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1508 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1509 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1510 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1511 will effectively disable old definitions.
1513 --- 2.0.28 2004/11/09
1515 Added yaz_log_time_format which specifies log format using
1518 Added yaz_log_module_level which returns mask for a module. Value
1519 is non-zero mask a if module is enabled; zero if disabled.
1521 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1522 in include/yaz/cql.h.
1524 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1526 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1528 Fixed bug #172: RPM builds does not enable SSL.
1530 Doxyfile.in part of dist. Doxyfile generated by configure.
1532 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1533 are given and the corresponding component does not exist.
1535 Extend CCL documentation in YAZ reference. Describe r=r.
1537 --- 2.0.26 2004/10/01
1539 Fixed MARC->MARCXML conversion to properly deal with
1540 fields, subfields, indicators having non-ASCII characters.
1542 Fixed MARC->MARCXML conversion so that ASCII control characters
1543 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1546 Added YAZ GFS support for conversion from Z39.50 surrogate
1547 diagnostics to SRW surrogate diagnostics.
1549 Bug fix: YAZ GFS did not return schema in explainResponse.
1551 --- 2.0.25 2004/09/30
1553 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1554 now converts recordSchema to elementSetName as well as schema URI.
1556 Fixed bug in COMSTACK that prevented HTTP request packages from being
1559 --- 2.0.24 2004/09/29
1561 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1562 does not require white-space before and after the dash in a range, e.g.
1563 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1566 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1567 due to new GCC removing "redundant" code.
1569 Added yaz-client commands scanpos and scanstep that sets preferred
1570 position and step-size for scan.
1572 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1574 Added CCL utility ccl_qual_buf which parses one or more CCL
1575 spec lines in a buffer.
1577 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1578 of name and value - ignoring empty lines and comments.
1580 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1582 Added odr_get_element_path which returns current element path for an
1583 ODR handle. This utility is useful in error handling or user-defined
1586 Added ODR_PRINT utility odr_set_stream which is is a more generic
1587 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1588 to a write function and pointer to close function. The close function - if
1589 non-NULL - will be called during odr_destroy.
1591 Fixed bug in CCL parser where truncation char was not removed from
1592 right side when truncation=both was in effect.
1594 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1597 --- 2.0.23 2004/08/11
1599 Fix buffer overrun in CQL parser when dealing with proximity (%).
1601 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1602 to UTF-8/UCS conversion is now only based on codetables.xml.
1604 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1606 --- 2.0.22 2004/08/06
1608 Add support for more "commit changes" in ZOOM (uses Extended Services).
1610 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1613 Yet another small fix for configure of SSL.
1615 --- 2.0.21 2004/05/14
1617 Fix SSL libs for configure when --with-openssl=DIR is given.
1619 --- 2.0.20 2004/05/10
1621 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1623 SSL comstack now uses yaz.pem certificate file on server side
1624 by default. Certificate filename can be configured by calling
1625 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1627 Fix bug regarding multiple calls to ZOOM_connection_connect.
1629 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1631 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1632 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1634 ZOOM now allows inspection of X509 peer certificate for verification.
1635 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1637 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1638 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1639 as "modular" but it simplifies things.
1641 Added cs_get_peer_certificate to that returns peer X509 PEM.
1643 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1644 NULL if SSL is unavailable.
1646 Documentation about MARC decoding tools.
1648 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1650 --- 2.0.19 2004/03/30
1652 Rename CHANGELOG to NEWS to follow GNU style packing.
1654 Fix bug with missing initialization of member in init_diagnostics.
1655 This bug affects threaded version of GFS server.
1657 --- 2.0.18 2004/03/20
1659 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1662 Ensure zlib.dll is packed with Windows install.
1664 --- 2.0.17 2004/03/17
1666 Fix encoding of xsd:string to use text instead of CDATA.
1668 Fix endless loop in CQL parser with unbalanced ".
1670 Use a more compact way to store MARC-8 conversion tables.
1672 --- 2.0.16 2004/03/16 Debian only
1674 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1677 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1682 --- 2.0.15 2004/03/01
1684 Another fix for decoding of XML packed records.
1686 --- 2.0.14 2004/02/25
1688 Fixes for Chunked encoding. White space not ignored after length spec.
1690 Update NS and use default NS for SRW diagnostic elements.
1692 --- 2.0.13 2004/02/23
1694 Implement ZOOM_resultset_cache_reset which resets record cache.
1696 Implement ZOOM_resultset_sort which sorts a result set.
1698 Implement chunked HTTP transfer.
1700 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1702 --- 2.0.12 2004/02/16
1704 Added member 'schema' to bend_explain_rr structure so that backend
1705 can specify explain record identifier. Defaults to Zeerex 2.0.
1707 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1709 --- 2.0.11 2004/02/16
1711 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1714 Added init command for yaz-client which sends "extra" init request.
1716 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1717 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1719 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1721 Make ZOOM error code for "invalid query".
1723 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1725 --- 2.0.10 2004/02/05
1727 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1730 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1732 Added option -p <file> to make Generic Frontend Server to write PID file.
1734 Added option -D to put Generic Frontend Server in background on its own.
1736 Make ZOOM C recognize option "password". If unset, "pass" is used
1737 (for backwards compatibility).
1739 Fixed a bug in Generic Frontend Server that could make it crash if a
1740 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1743 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1744 Must be issued before open, in order to be in effect.
1746 --- 2.0.9-6 2004/01/12 Debian/Windows
1748 Make the SRU server more picky WRT unknown params, etc.
1750 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1752 New YAZ client command, options, that sets Z39.50 options.
1754 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1755 options from a string of tokens (one token for each option bit).
1757 Update SRW diagnostic code messages.
1759 --- 2.0.9-5 2004/01/07 Debian/Windows
1761 Handle user defined stylesheet for SRW/SRU.
1763 --- 2.0.9-4 2004/01/06 Debian/Windows
1765 Fix bug in decoding of Content-Length.
1767 --- 2.0.9-3 2004/01/06 Debian/Windows
1769 Fix a bug with decoding of XML packed records.
1771 --- 2.0.9-2 2004/01/05 Debian only
1773 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1775 Fix bug in SRW/SRU diagnostics decoding.
1777 --- 2.0.9 2004/01/05
1779 Fixed bug in Generic Frontend Server which could drop records exceeding
1780 preferred message size. Reported and fixed by Irina Dijour.
1782 Fixed calculation of package size for structured records in Generic
1783 Frontend Server. Reported and fixed by Irina Dijour.
1785 Fixed namespace for SRW/SRU diagnostics.
1787 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1789 --- 2.0.8 2003/12/22
1791 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1792 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1795 CQL changes to reflect recent changes to the specification:
1796 * Documentation talks about context sets instead of index sets.
1797 * Documentation talks about indexes instead of qualifiers.
1798 * The CQL-to-PQF transformer's configuration file now uses
1799 "index.set.name = <attributes>" instead of the old form
1800 "qualifier.set.name = <attributes>". (Both forms are still
1801 understood but the latter is deprecated.)
1802 * CQL terms with no explicit index specified are now interpreted as
1803 cql.serverChoice instead of srw.serverChoice (which of course
1804 behaves exactly the same.)
1806 --- 2.0.7 2003/12/16
1808 MARC conversion can now generate ISO2709 output in another
1809 character set. yaz-marcdump uses this facility if you invoke it
1812 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1813 functions from there can be used from C++.
1815 --- 2.0.6 2003/12/04
1817 Frontend server now transfers memory from decoded packages to stream
1820 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1821 references to show up.
1823 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1824 the ZOOM Abstract API. The older names for the same options are still
1825 also supported for the benefit of old applications.
1827 ZOOM-C supports "implementationId" and "implementationVersion" options
1828 to go along with "implementationName". These allow the user code to
1829 specify identification strings to be sent to servers.
1830 Add OID for the new ExtLite attribute set.
1832 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1833 as requested/supplid by Ere Maijala <ere@atp.fi>
1835 For generic frontend server, reverse the order of
1836 "toolkit-supplied / application-supplied" strings sent as implementationId,
1837 Name and Version. Also, remove the spaces around the slash. This brings
1838 the GFS in line with the behaviour of ZOOM-C on the client side.
1840 Add function ZOOM_scanset_display_term.
1842 yaz-client shows scan displayTerm if present.
1844 Utility yaz-iconv is now installed by default along with the man page
1847 Extend configure check for OpenSSL to use pkg-config where available (such
1850 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1851 server to specify uid/gid/mask for socket using the format
1852 unix:[user=uid,][group=gid,][umask=mask,]file=path
1853 If file= is omitted the existing format is assumed, e.g.
1855 in which case the mask is 0666 (rw for everybody).
1857 Major restructure of YAZ source. All source in libyaz is in src directory.
1858 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1859 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1861 Added man page for utility yaz-marcdump (used to be called marcdump).
1862 yaz-marcdump is installed by 'make install'.
1864 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1865 of incoming package failed.
1867 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1869 Change prototype of odr_perror: add const to message string.
1871 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1873 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1874 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1875 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1876 DNS lookup. There should not be any compatibility problems with this
1877 assuming that blocking=1 or 0 is used.
1879 Fix bad reference in UNIX comstack in function cs_addrstr.
1881 Fix for compilation on AIX.
1883 The generic front-end server (server/seshigh.c) now supports returning
1884 Init diagnostics to the client in User-information-field, in
1885 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1888 --- 2.0.4 2003/09/04
1890 Allow any CQL relation (not just all,any,exact,scr).
1892 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1893 that features the same UI.
1895 Implemented command update0 in YAZ client which is equivalent to
1896 update but uses old of Ext Update ASN.1.
1898 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1899 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1900 Previously no OID was used for this info.
1902 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1903 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1904 returns 'malformed search term' otherwise.
1906 SortResponse member resultCount now set to NULL in sort handler of
1909 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1912 Add three new utility functions for translating OIDs between various
1913 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1914 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1915 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1916 char *oid_to_dotstring(const int *oid, char *oidbuf);
1917 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1919 Reverted modifications for ES Update definition for z_IU0Update
1920 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1921 is back to YAZ 2.0.2.
1923 String value attributes for CCL parser.
1925 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1926 which their FirstSearch server returns in Init responses, sometimes
1927 carrying useful diagnostic information when Init fails. This has the
1928 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1929 "z39.50/oclcui.asn", where its definition is somewhat different from
1930 what OCLC document on their web-site, as required to interoperate with
1933 Support for anonymous authentication in yaz-client. Use the command
1936 * Fix the OID of the Index Data-local "admin" Extended Service from
1937 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1938 the 1000, which indicates a locally-defined OID, was a mistake.
1940 --- 2.0.3 2003/06/20
1942 Fix CCL directive @case handling so that it affects string match for
1943 both CCL keywords and qualifiers.
1945 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1946 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1947 Decoder has been updated with ASN.1 changes as listed in
1948 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1949 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1950 z_IUUpdate, remains unchanged.
1952 ZOOM_record_get may now return a record in a specific character set.
1953 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1954 "from" is the character set of record as returned by target. "to" is
1955 the character set to be returned. If omitted, "to" is UTF-8.
1957 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1959 New ODR utility, odr_getelement, which returns name of element for
1960 which encoding/decoding failed.
1962 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1963 in cases where a required element was omitted.
1965 Bug fix: some MARC8 sequences were not converted.
1967 New ZOOM option "step" which specifies number of records to be
1968 retrieved in one chunk. Used in conjunction with "start" and "count".
1970 SRW support for yaz-client. Use scheme http: to use it, e.g.
1973 yaz-client no longer does (un)intelligent character set conversions
1974 by default. Can be enabled with charset and marc_charset commands.
1976 xmalloc trace fix for 64-bit systems such as DEC alpha.
1978 Solaris 2.6 compile fix.
1980 New function, cql_strerror() translates SRW error codes, as returned
1981 by cql_transform_error(), into human-readable English strings. Used
1982 in yaz-client diagnostics when appropriate.
1984 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1985 converts it into a type-1 query which is sent to the server. This
1986 makes CQL available for use with all Z-servers, as opposed to the tiny
1987 minority that can handle CQL queries themselves.
1989 --- 2.0.2 2003/04/28
1991 New Debian package layout similar to the Redhat Package layout.
1993 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1994 and search result respectively.
1996 --- 2.0.1 2003/04/25
1998 Redhat package is now several packages: libyaz (runtime libraries),
1999 libyaz-devel (development and documentation, and yaz (utility programs).
2000 Package spec file by Morten Bogeskov.
2002 New member 'schema' in struct bend_fetch_rr which the name of requested
2003 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2004 handler MAY set this to reflect the schema of the returned record.
2006 New member 'display_term' in struct scan_entry. GFS now sets member entries
2007 and allocates scan entries to be filled by user scan handler. In previous
2008 version, entries member was allocated by the scan handler. That still works,
2009 but the GFS will ignore member display_term - assuming it was NOT set by
2010 the handler. The fact that the GFS now allocates the entries both allows
2011 for new members and makes a scan handler easier to write.
2013 Fix CQL lex buffer overflow.
2015 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2016 SRU default recordPacking is string.
2018 SRU protocol support for frontend server.
2020 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2022 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2024 Added scan for the ZOOM shell (zoomsh).
2028 * String Identifers for Schemas (Amendment 5).
2029 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2030 Old definition for schema
2031 Odr_oid *schema; /* OPT */
2036 Z_InternationalString *uri;
2037 #define Z_Schema_oid 1
2038 #define Z_Schema_uri 2
2041 * resultCount parameter to Sort Response (Amendment 1).
2042 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2044 Support for SRW 1.0 over HTTP. This is an optional feature and
2045 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2048 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2049 on the same port. SRW SearchRetrieveRequests are mapped
2050 to bend_init,bend_search,bend_fetch,bend_close.
2052 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2054 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2055 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2057 ZOOM connections are SRW based if schem http is used for hostname
2058 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2059 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2061 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2062 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2063 distance=n, order=true/false, relation=le, prox unit=word. If
2064 n is omitted, distance 1 is used.
2066 Fixed problem with C compiler include path in wrong order.
2068 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2069 on Solaris. Patch from Ko van der Sloot.
2071 New MARC decode API. All new functions operate on a yaz_marc_t
2072 handle. The most important new functions are: yaz_marc_create,
2073 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2074 decode and destroy respectively. Decoder can produce formats
2075 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2076 include/yaz/marcdisp.h.
2078 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2079 to UTF-8, UCS-32, wchar_t or Latin-1.
2081 * Prototypes for yaz_iconv_-functions moved to separate header
2082 include/yaz/yaz-iconv.h.
2084 Make a few private functions 'static' in unix.c. This prevents
2085 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2087 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2088 are set when Init Response is received.
2090 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2091 but returns diagnostic set as well.
2093 New function yaz_strerror which is a portable wrapper for
2094 strerror/strerror_r/GetLastMessage.
2096 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2097 is returned for MARC. If type is "oai", then OAI MARC is returned.
2099 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2102 --- 1.9.2 2002/11/26
2104 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2106 Fix bad race conditions on SIGTERM and terminate gracefully in
2109 Move retrieval (data1) module to Zebra since nobody seems to be
2112 Add GRS-1 render for ZOOM using same format as yaz-client.
2114 --- 1.9.1 2002/10/05
2116 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2118 Fix broken ESpec handling in data1 module.
2120 SGML reader parses comments and makes them part of the data1 tree.
2122 Added several type casts so that YAZ compiles as C++ code.
2124 ZOOM didn't handle PDU encoding failures properly.
2126 Added more Bib-1 diagnostics (approved extensions).
2128 GNU configure: better check for iconv.
2130 More portable use of accept, getpeername. Check for socklen_t. Use
2131 int/size_t if socklen_t is not defined.
2135 PQF parser rejects bad queries - including those with extra
2136 characters in them. PQF parser used to silently ignore that.
2137 Cleaner API for PQF added, which allows you to get detailed
2138 error information for bad queries (see yaz/pquery.h).
2140 Fixed bug in ZOOM_record_get for type "database".
2142 Implemented mini iconv library supporting conversions between
2143 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2145 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2147 --- 1.8.9 2002/08/20
2149 Fixed ZOOM C record cache so that preferredRecordSyntax and
2150 elementSetName is used to check for already fetched records.
2152 --- 1.8.8 2002/08/02
2154 Added three members in bend_initrequest structure to facilitate
2155 character set negotiation.
2157 Fixed a bug in frontend server that could cause indefinite
2158 loops under rare conditions.
2160 Revised character set utilities (charneg.h) so that encoding
2161 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2163 For PQF, directive @term <type> sets term type for Scan/Search.
2164 Here <type> is general, string, numeric, null. The term type
2165 is inherited - just like @attr.
2167 New call odr_set_charset that sets character set conversion for
2168 international-strings on a ODR stream. Prototype is:
2169 int odr_set_charset(ODR o, const char *to, const char *from);
2170 The InternationalString is still represented as C string in YAZ
2171 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2172 won't). On the protocol level, you can use any encoding.
2174 Support for UNIX sockets in ZOOM.
2176 Solaris recv sometimes returns errno == ENOENT. It is treated as
2177 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2179 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2180 both client and server. Code by Morten Bogeskov.
2182 --- 1.8.7 2002/05/22
2184 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2185 that they can be used directly from Visual Basic. You must recompile
2186 your windows APP if you're using ZOOM.
2188 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2189 Commands "lang" and "charset" sets language and character set respectively.
2190 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2191 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2193 Attributes from multiple CCL fields may be OR'ed rather than merged
2194 using directive "@field or". Fields are still merged by default -
2195 equivalent to "@field merge".
2197 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2200 Fixed bug in zget for parameter ExtendedServicesResponse.
2204 --- 1.8.6 2002/03/25
2206 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2208 Client displays USR.1:SearchResult-1 (hits per term).
2210 Additional Search Info for search in Generic Frontend Server.
2212 Fixed CCL parsing of "field=s".
2214 WIN32 installer - using the excellent NSIS software from nullsoft.
2216 Fixed CCL parsing of "field = - <number>".
2218 Added function yaz_marc_decode that decodes MARC for line mode
2219 display or XML (similar to that used by JZKit).
2221 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2222 Z39.50. But ISO/ILL was, however.
2224 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2225 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2227 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2228 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2230 --- 1.8.5 2002/02/03
2232 New YAZ client features: Command completion and new commands:
2233 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2234 Code provided by Jacob Poulsen.
2236 New call oid_trav, that visits all registered OIDs via callback.
2238 Function ZOOM_record_get now returns const char pointer rather than
2239 void pointer. It saves a lot of type casts.
2241 For YAZ client, command "auth" now allows you to set authentication
2242 in IdPass style. It is enabled when three tokens are given - order
2243 is user, group and password.
2245 Fix memory leaks in MARC record handling for ZOOM.
2247 New option for YAZ client, -k <kilobytes> that sets
2248 maximum record size. Similar to -k option for generic frontend
2249 server and yaz-ztest.
2251 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2253 Prefix query parser reports "fail" when bad attribute set is given.
2255 Fix in MARC decoder. Proximity logging. Fix for attribute set
2256 in scan handler for server. Patches by Shigeru Ishida.
2258 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2261 Configure option --with-openssl=<dir> now works when a directory is
2262 specified. Patch provided by Morten Bogeskov.
2264 New option for YAZ client, -u <auth>, that sets authentication.
2266 ZOOM fix: error information was sometimes "missing", since error
2267 was cleared/reset too when it shouldn't.
2269 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2271 --- 1.8.4 2002/01/04
2273 Scan for ZOOM API. New object ZOOM_scanset. New functions
2274 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2275 ZOOM_scanset_destroy.
2277 New ZOOM function, ZOOM_connection_last_event, that returns type
2278 of last event (such as "receive data", "send data", "apdu received",
2281 New ZOOM option, schema, that specifies schema for retrieval.
2283 New CCL feature. Qualifiers can be aliases for one or more
2284 other qualifiers (if more than one is given, OR is used).
2286 ZOOM uses named result sets if target supports it.
2288 Two new YAZ client commands: . (dot, which sources a script of YAZ
2289 client commands), and ! (to execute shell command.). Implemented
2292 Working on Debian packages.
2294 --- 1.8.3 2001/11/19
2296 YAZ client enables named result sets only if target supports it.
2298 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2300 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2301 with key="host" to get same result.
2303 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2304 Function Z3950_resultset_record(s) returns references to records
2305 "owned" by resultset. To become owner use Z3950_record_clone.
2307 Function z_ext_record handles Extended Services. Thanks to
2310 --- 1.8.2 2001/11/12
2312 CCL Parser fix: ignore token comma when dealing with and-lists.
2314 Documentation updates for COMSTACK.
2316 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2317 Changed prototype Z3950_records. For some functions, int parameters
2318 were changed to size_t.
2320 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2323 New MARC decode/display function, marc_display_exl, which properly rejects
2324 non-ISO2709 records. YAZ client uses it.
2326 --- 1.8.1 2001/10/29
2328 Fix bug: local attribute set wasn't set correctly in PQF strings.
2332 * Old Z39.50 codecs no longer supported.
2334 Added ZOOM C binding. See http://zoom.z3950.org/
2336 Renamed states for COMSTACKs to avoid confusion with events.
2338 Implemented cs_look and proper cs_rcvconnect.
2340 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2342 Configure detects POSIX threads on OpenBSD.
2344 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2345 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2347 When error is returned from present handler, non-surrogate diagnostic
2348 is returned in present response (and fetch handler is no longer called).
2350 * Minor adjustments to pquery parser (PQF). Token characters may be
2351 escaped by using backslash (C-style).
2353 PQF parser allows string attribute values to be specified. For @attr,
2354 non-numeric characters after the equal-sign are treated as strings
2355 (e.g. @attr 9=title).
2357 CCL trunction character may be defined (@truncation in file)
2359 * function zget_ExtendedServicesRequest sets waitAction to
2360 waitIfPossible (was wait).
2362 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2365 CCL operator names may be set in field definition files (CCL_bibset).
2366 See ccl/bib1 for an example.
2368 Fixes in ASN.1 compiler for C++ compatibility.
2370 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2371 and "op_or" to avoid conflict with C++.
2373 Fixed problem with GNU readline detection on Redhat 7.0.
2375 Added step-size for Scan backend handler.
2377 Fixed bug that made the frontend server crash when no attribute
2378 set was specified for scan.
2380 Front-end server automatically switches to original working directory
2381 when installed as an NT service. Previously -w had to be specified to
2384 Added extended attributes for retrieval module (data1), so that data1
2385 records carry d1_readXML/SGML attributes. d1_read also supports
2386 null-data rules ( <tag/>)
2388 On UNIX when POSIX threads are available, a separate library libyazthread
2389 is created. Programmers should link with that library and the yaz library
2390 when using threads. The reason for the split was that some applications
2391 on Linux, such as Apache, doesn't work well when using shared objects that
2394 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2395 (or any frontend server) in SSL mode by specifying ssl: followed by
2396 address. Only tested on UNIX.
2398 Added feature for CCL module. Virtual structure s=al or s=ol generates
2399 and-list and or-list respectively instead of phrase search.
2403 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2404 log_mask_str. This was done to avoid name conflicts with other libraries
2405 (such as other PHP extensions).
2407 Added raw OID member for preferred record syntax (request_format_raw)
2408 and returned record syntax (output_format_raw) for backend fetch method.
2410 Config file yaz-config now accepts options so that it returns specific
2411 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2413 Shared library support for UNIX using GNU libtool.
2415 * Modified backend interface. Request/Response struct's replaced by
2416 one read/write C struct. For example bend_fetchrequest and
2417 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2418 Every handler - even search has to be registered in bend_init
2419 handler. This means that the YAZ library no longer refers to
2420 external functions and it makes it possible to make the whole
2421 thing a single DLL/SO.
2423 Added Segment handler for backend server.
2425 Added Zmbol/Zebra administrative functions to YAZ client.
2427 Threaded frontend server on UNIX (when POSIX Threads are available).
2428 Starting the server with option -T enables multi-threading.
2432 Added configure option --enable-comp/disable-comp to control use
2433 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2434 located in sub directory asn.
2436 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2437 in ${exec_prefix}/bin along with the other programs yaz-client and
2440 GNU automake used to maintain makefiles.
2442 Added several OID's.
2444 Changed retrieval module so that we can load records with no abstract
2445 syntax defined. Tagpaths in these records are fully composed of string
2448 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2452 On UNIX, the generated makefile now supports a proper 'make install'.
2453 The prefix can be set via GNU configure to set the install location
2454 (default is /usr/local).
2456 * YAZ programs client and ztest were renamed to yaz-client and
2457 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2458 locations, such as /usr/bin,/usr/local/bin,etc.
2460 * YAZ Header files were moved from include to include/yaz. YAZ Header
2461 files are referred to as include <yaz/log.h> rather than <log.h>.
2462 The YAZ include path (-I ..) is therefore the same as before. Programmers
2463 should update their #include statements or use -Ipath/include/yaz
2464 instead. The main motivation for doing this change is that YAZ header files
2465 can be installed in "standard" locations /usr/include,/usr/local/include
2466 without introducing conflicts, since ALL YAZ header files are stored
2467 in subdirectory yaz (under /usr/include for example).
2469 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2470 rather than project/workspace files. We switched because project files
2471 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2474 Changed name of logging function, logf, to yaz_log, to prevent name
2475 clash with some math-log functions. The YAZ header log.h defines logf
2476 to yaz_log (#define) so there should be no incompatibilities by this
2479 Added bend_start/bend_stop handlers for server. These handler are
2480 called on start/stop of server. For windows they are called whenever
2481 a service is started/stopped.
2483 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2484 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2485 in util/yc.tcl. The auto-generated C code structures are, in a few
2486 cases, incompatible with the old decoders. There are differences in the
2487 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2488 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2489 The preprocessor variable ASN_COMPILED is defined when the compiled
2490 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2491 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2492 wish to use the old encoders/decoders you can specify --disable-yc
2495 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2496 version so that it supports both new - and old version of DB Update
2498 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2499 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2500 change. The name parameter can be set to 0 in which no name is specified
2501 for the construction. The macros odr_implicit and odr_explicit sets name
2502 parameter to zero for the construction involved. New macros
2503 odr_implicit_tag and odr_explicit_tag are similar to the others,
2504 except that a name parameter is added. For programmers' that don't use
2505 ODR they probably only need to change the call to z_APDU and z_External.
2507 Added access control facility by interfacing the TCP wrapper library.
2508 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2509 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2510 name of the daemon and enables the access control as specified in
2511 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2513 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2514 den Dool <H.M.vdnDool@kub.nl>.
2516 Added reference ID parameter to most functions in server API - refer
2517 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2519 Changed name of ccl library to libccl.a (was ccl.a).
2521 Fixed bug in decoder for Explain (Category TargetInfo).
2523 Added support for GNU readline in client. Thanks to Jacob Poulsen
2524 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2526 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2527 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2528 IMPLEMENTATION! This change was made to the development version before
2529 the ZIG decided to retract the amendment. If any users MUST be
2530 compatible with the original Update definition, PLEASE CONTACT US, and
2531 we will include a separate definition corresponding to the old Update
2532 ES. Note that because of the change to the ASN.1 of the
2533 TaskPackageRecordStructure we cannot define a single structure that
2534 will support both versions.
2536 * Added const modifier to buffer parameter for some ODR/BER encoding
2537 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2538 completeWAIS, odr_dumpBER.
2540 Fixed bug in client.c which caused a crash when a scanResponse didn't
2541 contain positionOfTerm.
2543 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2544 * will cause an error in a client if a non-YAZ target sends both a
2545 * list of Scan entries and non-surrogate diagnostics.
2547 Retrieval module enhancements. Tag sets may be typed in the reference
2548 to it. From the .abs-file the "tagset" directive takes a third optional
2549 integer type for the tag set referenced. From a .tag-file the "include"
2550 directive takes a third optional type as well. The old "type" directive
2551 in the tag set itself is still recognized but acts as the default type
2554 Backend interface change. Individual Scan terms returned from bend_scan
2555 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2556 in include/backend.h.
2558 Retrieval module enhancements. Multiple tag sets and attribute sets may
2559 be specified in abstract syntax specs. Revised the error/warning for
2560 logging messages reported by the retrieval module when reading the
2563 Object Identifier system (oid_..) changed. The API is backwards
2564 compatible but the oid-routines now allocates new OID's when needed.
2565 Raw OID's may be specified in oid_getvalbyname.
2567 YAZ now uses GNU configure to generate Makefile(s).
2569 * Minor changes in some of the member names of DeleteResultSetRequest and
2570 DeleteResultSetResponse. See include/proto.h.
2572 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2573 and added member 'languages' in TargetInfo (which was missing).
2575 Changed the way attribute sets are handled in the retrieval
2576 module. These are now cached, just like the abstract syntaxes
2579 Changed YAZ so that it links with compiled ASN.1.
2581 Added Explain-schema definitions and mapping routines. The following
2582 Explain categories have been implemented: AttributeDetails,
2583 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2585 Fixed minor bug in Windows version of Server Library.
2587 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2589 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2591 Added EXTERNAL: UNIverse Resource Report (non-standard).
2593 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2594 ENUMERATED and SET OF.
2596 * Added 'const' to some of the char pointer arguments for the
2597 functions, data1_read_node, data1_getelementbytagname,
2598 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2601 Fixed bug in data1_insert_taggeddata - the last_child member of
2602 parent wasn't initialised.
2604 * Changed data1_read_record and data1_read_node so that the supplied
2605 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2606 doesn't refer to any parts of the "SGML"-buffer.
2608 Fixed bug in server library (Windows version of statserv_remove).
2610 * Changed code so that it compiles as C++. The type definition
2611 of Odr_fun which is a member of Odr_arm was changed. The result is,
2612 that an explicit typecast is needed for the fun pointer when
2613 using Odr_arm - as in:
2614 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2616 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2618 Implemented the new structured date and time definition as approved
2619 by the ZIG. Added schemaId element to the specificTag in Espec-1
2620 (also approved at the last ZIG). Thanks to RVDM.
2622 Added some Object identifiers (RVDM).
2624 Changed the Update Extended Service (RVDM).
2626 Added command "refid" to client which specifies referenceId for
2627 the following requests.
2629 Implemented extended service handling for server. See ztest.c
2630 for an example as well as backend.h. New handlers are registerd
2631 in the Init handler.
2633 * Changed interface for sort in server.
2635 Added new members to statserv_options_block. It allows a server
2636 to read options from another source than just the command line. Thanks
2637 to Charles Woodfield.
2639 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2640 renamed to zboolean. Some C++ compilers complained about the name.
2642 Minor changes to gils.abs. Added index 's' (sort) on title
2643 and date/time-last-modified.
2645 --- 1.4pl2 1998/1/30
2647 Fixed bug in server library regarding inetd mode (-i). This bug
2648 was introduced by release 1.4.
2650 --- 1.4pl1 1998/1/29
2652 Added sort facility in client and backend server interface.
2654 Fixed problem with dependencies in Makefile(s).
2656 Fixed bugs for encoders/decoders of extended services and
2659 Implemented sub-tree feature for schemas. Sub-trees are
2660 referenced in *.abs-files. See explain.abs for an example
2661 of the use of this feature.
2663 Modified bib1.att; local attributes for ANY didn't include
2664 ANY itself (only affects use of the retrieval module).
2666 Fixed bug in plain SGML reader in function data1_read_node:
2667 tags with prefix "var" was incorrectly interpreted as variants.
2669 Added feature "sub-schemas" to enable references to - and definitions
2670 of - group of elements.
2672 * Removed member parent from type data1_element (in data1.h).
2674 Implemented function odr_nullval() that returns the value of
2677 * Removed member num_children from data1_node (in data1.h).
2679 Made NT service interface part of the server library. The
2680 function statserv_main uses the NT service when required and
2681 calls the statserv_start / statserv_close routines.
2683 Routine zget_SearchRequest and zget_PresentRequest fills
2684 resultSetName/Id member with "default" instead of "Default".
2686 Fixed memory leak in server. Request queue member wasn't freed.
2688 Fixed nmem_exit so that memory is freed.
2692 Revised the CCL parser utility to be thread safe.
2694 Added function, oid_ent_to_oid, to replace the function
2695 oid_getoidbyent, which is not thread safe.
2697 * Added nmem_init and nmem_exit to initialize and release
2698 NMEM resources. Function nmem_init should be called once in the
2699 initial thread before NMEM/ODR is used. statserv.c and client.c
2700 have been changed accordingly. The change was necessary to make
2701 NMEM thread safe. The NMEM memory pool is shared amongst threads
2702 in a process. Unix-based applications will still work fine without
2705 Added NT Services interface for the the Z39.50 (statserv) Server.
2706 Refer to the ztest.c source on the usage.
2708 Windows 95/NT port using MSVC5.0. Project files are included in the
2711 * Defined new 'global' handle for the retrieval (data1) system. The
2712 new handled, data1_handle, describes the state of the data1 system.
2713 This handle is passed as first argument to virtually all
2714 data1 related routines. The functions data1_create and data1_destroy
2715 creates and destroys a data1 handle respectively.
2717 Added ODR encode stream member to all backend request structures
2718 init, search, scan etc. This stream should be used to allocate all
2719 memory used for the response when thread safe operation is needed.
2721 Changed the comstack utility, cs_addstr, to be thread safe. The
2722 returned hostname string returned by the function is now part the
2725 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2726 function. The cs_straddr takes a COMSTACK handle as argument, so this
2727 function must be used after cs_create and before bind/connect.
2728 This function is thread safe.
2730 Moved test server to 'ztest' directory - generic server code still
2731 in 'server' directory.
2733 Made prefix query (pquery.c) utility thread safe.
2735 Added new function modifier YAZ_EXPORT to 'export' public DLL
2736 functions when using windows (see include/yconfig.h).
2738 Added definitions to the OID database (util/oid.c) (RVDM).
2740 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2742 Added call to ccl_rpn_delete in client program.
2744 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2745 release of RPN structure.
2747 Added support for C++, headers uses extern "C" for public definitions.
2748 With input from RVDM.
2750 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2751 Thanks to Ronald van der Meer (RVDM).
2753 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2755 Added support for private extensions to the OID database
2756 (oid_setprivateoids()). Thanks to RVDM.
2758 Added optional, physical ANY (key replication)
2760 Fixed null-reference problem in GRS-1 output filter.
2762 Proximity operator added to Prefix Query Format (PQF).
2764 In test client command "base" accepts multiple databases.
2766 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2770 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2772 Smallish bug-fixes in the new encoders/decoders (explain).
2774 Bug fixed in DeleteRequest.
2776 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2778 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2780 Added SOIF syntax (using private OID for now) to retrieval module and client.
2782 Added Update extended service.
2784 Added SearchResult-1 additional info structure.
2786 Added optional CCL (ISO8777) interpreter as separate module. Available
2789 --- 1.2 1996/6/10 (1st anniversary release)
2791 Added Summary record syntax. Lightly tested.
2793 Added OPAC record syntax. Untested.
2795 Added ResourceReport service encoders/decoders. Untested.
2797 Fixed bug in z_Unit - wrong tagging on unitSystem.
2799 Fixed bug in the DiagRecs decoder.
2801 Added options for max PDU size and session timeout to frontend-server.
2803 Added documentation of query-language parsers and other supporting utilities.
2805 [frontend-server] Added Attribute set to the bend_scanrequest API.
2807 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2808 surrogate diagnostics were generated.
2810 [retrieval] Allow multiple local values for attribute.
2812 [retrieval] Allow multiple attributes per element in .abs files. index type.
2814 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2816 --- 1.1pl2 1996/4/10
2818 Minor changes, mostly specific to Zebra's requirements (retrieval)
2822 Repaired bug in frontend server when running multiple listening
2823 endpoints in dynamic mode.
2825 z_External() now won't break if a known, ASN.1 value comes encapsulated
2826 in an octet-string. The value will pass through unmodified in an Odr_oct.
2828 Added a bit of code to the demo client to decode & display
2829 ASN.1-structured records represented in the octet-aligned branch of
2830 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2832 Added z_ext_getentbyref() to the ASN module. Doc updated.
2834 * Completed the SCAN definition in the ASN module. This may break SCAN
2835 code based on older YAZ-versions at compile-time. The fix is easy -
2838 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2839 under the SCAN definition. Remember to initialize this, server-people.
2841 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2842 that this does not extend to ODR and ASN.
2844 Comstack allows insertion of established socket (primarily for
2845 inetd-operation of servers). Doc updated.
2847 Front-end server can now start from the inetd in TCP mode. Doc
2850 --- 1.0pl4 1996/1/24
2854 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2855 the rank and record number.
2857 Adjustments to the frontend server.
2859 Fixed diagnostic BER dumper. It ignored the file argument.
2863 Various changes to retrieval module.
2865 Changed the union discriminators of the protocol files from enums to
2866 ints paired with #defines.
2868 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2871 *Changed operator in the RPN structure to 'roperator', again to avoid a
2874 Fixed problems in Explain decoders/encoders.
2876 --- 1.0pl2 1995/12/6
2878 Memory bug in log module fixed.
2880 --- 1.0pl1 1995/12/5
2882 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2884 Bug in Explain DatabaseInfo module fixed.
2886 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2890 The shift to v1.0 signals that we now consider the *core* functionality
2891 of YAZ reasonably stable (the core being more or less equivalent to
2892 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2893 tested (Explain not at all - though that will happen soonish).
2895 Minor changes to code to support Windows port.
2897 Various minor changes after we're getting to use GRS-1 & co. more.
2899 Added Espec-1 format.
2901 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2902 of the protocol and it cannot be selected when encoding (maps into 'string'
2903 when decoding). Needed to talk to some servers.
2905 Demo client can request simple element set names.
2907 Added Diagnostic Format encoders/decoders.
2909 Added simple Close handling to frontend server (no hooks for resource
2910 reporting yet), and demonstration client.
2912 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2914 --- 1.0b3 1995/08/24
2916 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2917 handled incorrectly when records were requested in the searchResponse. This
2918 will only affect you if you use the frontend-server.
2920 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2921 Test-client will ask for and print GRS1. Ztest will return dummy records
2924 Added Explain encoders/decoders to the service-level API. Untested.
2926 Added Extended Services: Item Order encoders and decoders to the Service-
2927 level API. Untested. We could use a recent copy of the pertinent bits
2928 of the ILL protocol to add those bits.
2930 Added diagnostic format 1 encoders/decoders to the service-level API.
2933 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2934 odr_cons.c, which causes a more correct output.
2936 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2937 was always set to 0 when no records were requested in the searchRequest.
2939 * Added better external-handling. This shouldn't harm old code that
2940 *encodes* externals. It can break code that looks for a
2941 'single-ASN1-type' representation, since those types that are known
2942 are now decoded immediately. Look at the SUTRS sample code in
2943 seshigh.c and client.c. Documentation updated.
2945 Handling of structured records in bend_fetchresponse. Length -1 marks
2946 structured record, type is deduced from format field.
2948 --- 1.0b2 1995/06/27
2949 Fairly quick maintenance release to add SUTRS support.
2951 Fixed handling of SUTRS records in the demonstration client.
2953 * Added format field to the bend_fetchrequest and bend_fetchresponce
2954 structures of the backend API (frontend server). When the record is
2955 returned, the value of the format field is mapped to an OID. The
2956 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2957 of the record. The special value VAL_NONE in the bend_request means
2958 that no specific format was requested by the client. Documentation
2959 updated accordingly. Test server (ztest) will return a fixed dummy
2960 SUTRS record if your client requests SUTRS.
2962 Documentation updated accordingly.
2964 You can now set external libraries and RANLIB support in the top-level
2968 First public release.
