3 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
4 resulting CQL node (tree) in a new node CQL_NODE_SORT.
6 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
7 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
8 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
9 Note that the CQL sortby spec is only converted when the GFS is already
10 converting from CQL to RPN (cql2rpn element).
12 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
13 specify whether to collapse delimitors or not. The existing nmem_strsplit
14 do collapse (collapse parameter = 1).
16 Windows installer: For NSIS, set InstallDir depending on x86/x64.
18 Rename internal func yaz_use_attribute_create. While non-static, this
19 function is not declared in a public header.
23 Add -lCrun when linking with ICU on Solaris.
25 More quicks character set conversions for OPAC records.
29 fix problem with record_render: records were converted (character set
30 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
34 SRU: add methods for handling DADS SRU-proxy facets.
36 Separate OPAC record character set for ZOOM_record. yaz_record_render
37 allows a character set given as charset=from/opacfrom,to where 'from' is
38 the character set of a bibliographic record, 'opacfrom' is character set
39 of OPAC record and 'to' is the target character set.
43 yaz-client: show may XML format records. Command show followed by 'format'
44 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
47 src/stemmer.c: Avoid using unnamed union. It is not supported by some
50 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
53 Update yaz.spec to operate on both SLES11 / Centos 5.5.
55 RPM: Release includes 'indexdata' name. Use indexdata in release name so
56 this package can be distinguished from other vendors.
58 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
59 as determined by configure
61 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
63 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
64 returns no error and no record, the present request is considered
65 partial (only a subset of the records could be returned by backend), and
66 so it is appropriate to set Present Status to partial-4.
70 Move yaz-config man pages to section 1.
72 More documentation about SOLR.
74 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
75 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
76 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
77 peers on some Linux systems. However, in general that does not work
78 so YAZ can not rely on that to work. Debian changed behavior in this
79 respect from Debian lenny to Debian squeeze (still testing as of Oct
81 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
83 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
87 Fix yaz-config output: echo_source not set correctly by configure.
91 SOLR WebService support for yaz-client and ZOOM.
93 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
97 Z39.50 facet support. Facet specifications are passed for search in
98 other-information with ASN.1 as defined in facet.asn and OID
99 .10.1000.81.5 . Facets are expressed as an Attribute list as known
100 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
101 3 is limit (number of entries to get in response). yaz-ztest returns
102 dummy facets if a client asks for them.
104 --- 4.0.11 2010/07/09
106 CCL fixes: bug 2895 and bug 3539.
108 GR1-display: add comma in display - was removed by mistake in
111 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
113 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
115 --- 4.0.10 2010/06/18
117 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
118 result set from a connection. The result set will be on its own
119 thereafter; no operations on it will perform retrievals from a target.
120 Only cached copies are returned.
122 ZOOM C:fix case for HTTP servers responding with Connection:close.
123 Ensure that if there is a current task it is resumed (like fetching
124 more records in a result set) . Bug #3484.
126 PQF parser: use odr_atoi for Odr_int (not atoi)
128 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
129 values that contain any non-digits are treated as string attributes
130 (previously decoding only checked for leading character ([0-9]). PQF
131 encoding: attribute string values are not surrounded by double-quotes.
135 New utility for managing threads - thread_create.h.
137 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
138 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
139 but YAZ' implementation do.
141 Fixes for yaz_cond-functions on Windows 7.
143 DLL export more symbols.
145 zoomsh: show record do NOT render opac.
147 Remove *.la files from Debian and RPM packages.
151 Debian package libyaz-dev depends on libgnutls-dev again (was
152 removed in YAZ 4.0.6, but due to Libtool it is still needed
153 even though yaz-config do not list libgnutls libs).
155 ZOOM: Use only one WRBUF for returning string results for
156 ZOOM_resultset. Reduces memory usage for ZOOM in general.
158 ZOOM: ZOOM_connection do not use a shared pointer to
159 ZOOM_resultset after ZOOM_resultset is destructed by
160 user. Reverts to YAZ 4.0.4 behavior.
164 record-conv: fix problem with at least one XSL conversion -
165 due to probably incorrect usage of XML XSL documents.
169 Fix yaz-config for static mode and the use of SSL (gnutls).
173 Forward decl timeval struct in mutex.h and gettimeofday.h.
175 yaz-config: fix 'static' mode linking.
179 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
180 are wrappers for pthreads or Windows. For Windows these are put in
181 a separate DLL: yaz_cond4.
183 libyaz.la (whole source) is compiled with thread. If thread support
184 is enabled enabled, all source of YAZ is compiled with treading support.
185 This allows core utilities such as yaz_log to use thread facilities.
186 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
187 thread utilities. This commit moves mutex utilities (mutex.c) from
188 libyaz_server.la to libyaz.la.
190 yaz-json-parse displays leading text until error.
194 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
195 patch from Giannis Kosmas.
197 SRU: no longer URL encode SRU database. The URL for an SRU server is
198 a URL and such is alreeady encoded - at least when given with leading
199 http:// or https://. This reverts behavior to YAZ 3.0.50.
201 Support for new MARC XML notation TurboMARC which like MARCXML is a
202 complete representation of MARC/ISO2709.. This one, however, is more
203 compact and allows for faster processing with XSLT. TurboMARC can be
204 used in the marcdisp.h API, from the yaz-marcdump utility and from
207 yaz-ztest can be configured - via the database - to perform certain
208 delays when it performs operations search, present and single record
209 fetch. This allows testers to make yaz-ztest act as a real or even slow
210 Z39.50 server. Refer to the yaz-ztest man pages for details.
214 wrbuf_destroy allows NULL WRBUF passed to it.
216 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
218 Add ZOOM_connection_close.
220 No fixed size buffers for ZOOM shell - bug #3257.
222 tstodr: make it work on s390 platform.
224 New icu iterator-functions. The new icu_iter-functions makes it possible
225 to use ICU chains from many threads.
227 yaz-client: better syntax check for show command.
231 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
234 New simple local-file XML include facility which allows file glob-patterns.
235 Refer to yaz/xml_include.h.
237 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
240 ZOOM_record_get supports new parameter "format" which makes it format XML
243 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
244 JSONText in ECMA-262) is JSONValue, not JSONObject.
248 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
249 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
251 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
252 POSIX/Unix builds .so with major version 4.
254 Remove old LOG_-defines from log.h. They have been obsolete and
255 undefined by default for the last 5 years.
257 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
259 GFS: Remove socket (int *fd) from search_rr handler. The socket
260 descriptor ptr is a facility that allowed a search handler to supply
261 a socket which would serve as a callback - when search was complete.
262 This facility has now been in use for years.
264 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
265 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
266 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
267 returns 'const char *' rather than 'char *. The returned string is
268 read-only and should not be modified by applications. COMSTACK cs_close is
269 now a void function - it no longer returns int. No applications check for
270 the value and the implementations has always returned 0.
272 ZOOM: use size_t for scan hit counts and str size. Functions
273 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
274 occ (hit count) and len (string length) are now of type size_t pointer
275 rather than int pointer. This is to be able to represent large hit counts
276 and to also just to use the proper type for string length (strlen result).
278 New JSON parser. Refer to include/yaz/json.h .
280 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
281 Used to be int in some cases. Many wrbuf_-functions used to return an int
282 indicating some length.. These return values were never used. And so they
285 ODR: odr_malloc, odr_total now takes size_t for size.
287 clone_z_type: fix leak; occurred for encoding failures.
289 --- 3.0.52 2009/12/03
291 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
292 bug was introduced in 3.0.51.
294 --- 3.0.51 2009/12/02
296 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
298 tcpip comstack: fix leak for getaddrinfo.
300 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
301 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
302 Decoding of SRU "path" database is performed by private function
303 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
304 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
306 yaz-client: honor base command for SRU. Change when database setting
307 is applied for SRU and ensure it is kept when a connection is reset.
308 Change also the way errors are displayed or SRU (decoding of packages).
310 --- 3.0.50 2009/11/02
312 Add support for extra request / response data for SRU codecs and GFS.
313 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
314 for extra data response buffer and length. For the GFS, both request
315 and response data (XML) is carried in extra_args and extra_response_data
316 for the search handler. Patch by Ko van der Sloot.
318 ZOOM: For queries that cannot be converted to the specified rpnCharset,
319 ZOOM now returns a diagnostic on the client-side ('invalid query' /
320 10010). This fixes bug #2113.
322 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
323 cmdfile included a 'quit' command that would result in a memory violation.
325 --- 3.0.49 2009/10/01
327 Make a number of functions defined in xmlquery.c static. These have
328 never been declared in a public header file (yaz/xmlquery.h) and was
329 made public by mistake.
331 Improve speed of character conversions (iconv utilities). This makes
332 conversions from MARC-8 faster.
334 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
335 unless type desired is "raw". This will prevent type "xml" from
336 returning ISO2709 .. Which obviously can not be XML parsed.
338 Fix memory leak in ZOOM that would occur if option apdulog was used
339 on a re-used connection.
341 Frontend server logs HTTP requests.
343 Frontend server now sends Z39.50 close when it times out (sesssion has
344 been idle for too long). Versions 2.0.30 and earlier also sent close.
345 But due to a mistake this was disabled in all versions after that, i.e.
346 the server would just close the socket immediately.
348 yaz-client emits a better message when receiving an unrecognised
349 userInformationField.
351 Skip zero-length subfields when decoding ISO2709. This rare case happens
352 if a record has two FS characters in a sequence. Without this patch
353 there would be a reference beyond char array in using_code_len fragments
356 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
358 --- 3.0.48 2009/08/28
360 The show command offered by the zoomsh command now takes a 3d optional
361 parameter type which is what is passed to ZOOM_record. If the type
362 argument is omitted, "render" is used.
364 RPN to CQL conv may use USE string attributes (bug #2978).
366 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
368 --- 3.0.47 2009/07/08
370 Function yaz_xml2query allows a diagnostic element in the PQF XML
371 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
372 code and additional info respectively.
374 The BER BOOLEAN is now the integral type Odr_bool which still happens
375 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
376 typedef'd to Odr_int. This is still an integral 'int', but it may be
377 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
378 ASN-1 compiler as well as programs has been updated to use the new types.
380 --- 3.0.46 2009/06/08
382 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
383 only the bibliographic record was rendered. For type=opac, an OPAC
384 record is only returned if it is present.
386 iconv: small fix for encoding of advancegreek.
388 yaz-client: avoid double display of SRU/SRW records (bug #2798).
390 yaz-client: option auto_reconnect=on really reconnects.
392 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
394 server: avoid null ptr ref for for yaz_poll errors.
396 build: fix RPM build for RHEL 5.3.
398 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
400 --- 3.0.45 2009/03/31
402 Fixed bug #2709: TCP connect returns Invalid argument.
404 Fixed compilation for mingw.
406 Honor charset for raw records (ZOOM_record_get).
408 Fixed use of errno for threaded mode that was seen on Solaris 10.
410 Fixed argument passing with blanks in value for Windows Service.
412 Disable YAZ' own log rotate by default (no 1 GB limit).
413 The variable l_max_size which specifies the log file limit is set to 0
414 (DISABLED): This is due to the fact that YAZ is most often deployed using
415 logrotate. Also YAZ can not perform log rotate because of unsufficient
416 permissions (setuid).
418 --- 3.0.44 2009/02/17
420 List supported encodings in man page for yaz-iconv.
422 Fixed missing SSL libs for --libs output
424 Re-established OID record syntax application-xml. Nobody should use it
425 but we don't want to change soname because of this symbol being absent.
427 --- 3.0.42 2009/02/02
429 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
431 Added member named_result_sets for init handler struct for the GFS. This
432 allows a server to disable named result sets.
434 Removed OID record syntax application-xml.
436 Added support for rule-based transliterator for ICU wrapper of YAZ.
438 Fixed bug #1902: yaz-icu XML output.
440 Make YAZ checks Emacs friendly.
442 BITSTRING value shows value. Bug #2346.
444 ISO2709 decoding: skip control characters from indicator data.
446 Omit sort key by default in yaz-icu's output.
448 Allow combined single char options (again) for YAZ' options function.
450 Utility yaz-marcdump got option to display YAZ version (-V).
452 Allow YAZ to use ICU 3.4.
454 Added new ICU test case which illustrates removal of diacritics.
456 --- 3.0.41 2008/12/29
458 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
460 --- 3.0.40 2008/12/29
462 For configure, using option --without-xml2 also disables Libxslt/Libexslt
465 Fixed bug #2352: yaz-marcdump crashes for certain record.
467 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
469 Added support for Danmarc2 to UTF-8 conversion.
471 Added support for ISO5426 to UTF-8 conversion.
473 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
474 implementation version.
476 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
478 --- 3.0.38 2008/11/10
480 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
481 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
483 ZOOM C now interprets databaseName option for ZOOM connection as path
486 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
488 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
490 Dummy Libxml2 types no longer defined in headers of YAZ'.
492 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
495 --- 3.0.36 2008/09/26
497 Various ODR chapter fixes.
499 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
501 Added missing source for Windows compilation, mutex.c.
503 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
505 For SRU connections in ZOOM all records up to "count" are now fetched.
507 Fixed crash in generic frontend server (and yaz-ztest) which occurred
508 in Windows due to bad error handling for Libxml2.
510 Added facility for sending arbitrary records (ASN.1 any) using
511 ZOOM C's Extended service update. Patch by Sam Reynolds.
513 New options for ZOOM C's connection, logapdu which makes ZOOM log
516 --- 3.0.34 2008/06/18
518 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
520 --- 3.0.32 2008/06/12
522 Fixed memory violation that could occur when decoding UTF-8. This bug
523 was only present in 3.0.30 of YAZ.
525 --- 3.0.30 2008/06/06
527 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
528 GNU TLS is used by default (if found).
530 yaz-ztest returns OPAC records if a client asks for OPAC.
532 Improved speed of MARC-8 encoding.
534 Added support for lossy and loss-less MARC-8 encoding.
536 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
538 Added new Windows Service wrapper (sc).
540 yaz-client's itemorder command may now send a file.
542 Fixed yaz-marcdump to allow the use of NS prefix for record element.
544 Added new function yaz_log_xml_errors.
546 Allow (but warn) unknown XML attributes in MARCXML parsing.
548 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
550 The UTF-8 to MARC-8 conversion now uses a different set of characters
551 for Greek symbols. Bug #2120.
553 --- 3.0.26 2008/02/21
555 Added yaz_daemon (daemon.h).
557 Fixed bug #2068: pkg-config trouble
559 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
561 --- 3.0.24 2008/01/28
563 Document --with-xml2 option.
565 Added OPAC XML XSD (etc/opacxml.xsd).
567 Allow glob mask for name attribute in retrieval element for the
568 generic frontend server's retrieval facility.
570 Changed yaz_poll_poll to return yaz_poll_except for all returned events
571 except POLLIN/POLLOUT.
573 Fixed error handling in cs_listen. Bug #2037.
575 --- 3.0.22 2008/01/20
577 Fixed version in yaz/yaz-version.h.
579 Fixed bug #2027: Crash when closing connection.
581 Changed configure so that ICU support is only enabled if only ICU
582 and Libxml2 is available (because the ICU chain is XML based).
584 --- 3.0.20 2008/01/15
586 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
587 is built. Only this DLL depends on the ICU runtime.
589 yaz-ziffy is no longer part of YAZ. It is distributed separately by
590 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
592 Changed license of CCL module to 'Revised BSD'. After consultation with
593 remaining members of the original EUROPAGATE consortium, we are re-issuing
594 the CCL module without a separate license. The software was developed by
595 Index Data as part of a research project. The special license was included
596 to help feed usage information back to the project consortium to support
597 project evaluation. At this time, the project consortium has long-since
598 disbanded, and the majority of the original principals have retired. At the
599 same time, we have significantly modified the software during the following
600 years, to the point where very practically no original code remains. To
601 simplify re-use of the software, we have contacted those members of the
602 consortium who could be reached, and agreed to re-issue the module as a
603 proper part of the YAZ package.
605 Tcl scripts uses /usr/bin/tclsh as preferred shell.
607 CQL closer to being version 1.2 compliant. CQL also allows free-form
608 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
611 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
612 bug could make Extended services handling crash in the ZOOM layer. This
613 bug was only present in YAZ 3.0.18.
615 --- 3.0.18 2007/12/19
617 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
620 yaz-marcdump reads and writes collection wrapped records.
622 Handle OPAC for record conversion module.
624 Fixes for ICU wrapper.
626 Allow ICU libs to be controlled with --with-icu .
628 --- 3.0.16 2007/11/12
630 Added yaz_poll which is a wrapper for select/poll. When poll is available
631 and non-buggy, it is used, by yaz_poll . This allows more than 1024
632 sockets to be in use.
634 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
635 functionality through an XML based configuration (ICU chain). This system
636 is useful for search facilities such as Pazpar2 and Zebra that needs to
637 perform tokenization of indexed material. The ICU code in a separate
638 library libyaz3_icu.a.
640 Added HTTP tunnel facility for COMSTACK, bug #1752.
641 This is a facility that allows a Web proxy, such as squid, to tunnel
642 Z39.50 traffic. This facility is "transparent" to must applications
643 using YAZ. It's enabled by using pseudo transport connect: followed by
644 the proxy address, followed by command, then follwed by he regular
645 "virtual" addresss. For example,
646 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
648 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
650 --- 3.0.14 2007/09/21
652 Fixed bad memory reference in ZOOM_record - cuased by member not being
653 initialized. This was a problem only in YAZ 3.0.12.
655 Fixed bug in conversion from MARC to XML: Non-XML characters in control
656 fields were not removed.
658 Changed the way C code is generated from codetables.xml. Made a MARC-8
659 conversion trie for each characterSet section rather than codeTable.
660 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
661 of codetables.xml from Larry Dixson, LOC. Bug #1464.
663 --- 3.0.12 2007/09/12
665 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
666 from ZOOM_record_error).
668 ZOOM C function ZOOM_record_get returns record schema for type="schema".
670 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
672 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
674 Better SRW-to-Bib-1 diagnostic mapping.
676 ZOOM C and yaz-client announces SRU version 1.2 by default.
678 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
681 Fixed in yaz_sru_decode to allow other version than 1.1.
683 --- 3.0.10 2007/08/22
685 Added support for SRU scan for ZOOM.
687 Added support for the use of the older versions or Extended Service
688 Update in ZOOM. To faciliate this, an option "updateVersion" may be
689 set to the version , 1=first, 2=second, 3=third. The third version is
690 what ZOOM C has used so far. And that, obviously, is the default.
692 Added support for CCL queries in Z39.50 queries sent to the GFS (and
693 therefore in Zebra and in SimpleServer-based applications). The new
694 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
695 qualifier file used to transform incoming CCL queries into Type-1 RPN,
696 which is passed into the back-end search callback function.
698 Added support for HTTP Basic authentication in clients: the SRU/W
699 codec encodes the username/password elements of the PDU structure
700 appropriately, and these may be set using the "user" and "password"
701 options in ZOOM-C applications (the same options that are used for
702 Z39.50 authentication).
706 Fixed bug #1208: SSL appears to be broken in ZOOM.
708 Fixed bug #1206: Libxml2 include path weirdness.
710 Added oid_name_to_dotstring.
712 Allow elementSetName to be specified for ZOOM C record update.
714 Allow waitAction to be specified for ZOOM C based for Extended Services.
716 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
717 syntax OID. Bug introduced in YAZ 3 series.
719 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
723 Fixed bug #1157: yaz-client does not read .yazclientrc from current
724 directory. yaz-client now reads commands from file given by option -f
725 if specified; then tries to read .yazclientrc in current directory.
726 Failing that, it reads .yazclientrc from user's home directory.
728 Added support for correlationInfo Note and ID for Record Update via
731 Added yaz-client command querycharset which specifies character set for
732 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
733 (termListAndStartPoint).
735 Charset ISO5428:1984 is an alias for ISO5428-1984.
737 Implemented a way to perform scan in a result set using Z39.50. This
738 is achieved by attaching the result set name in the characterInfo
739 (type InternationalString) of OtherInformation in the Scan Request PDU.
740 The result set is identified in the otherinformation by the new OID:
741 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
742 This allows for scan in result set and faceted search . Zebra did some
743 of this in the APT term using attribute type 8 and value being result
744 set. Using the OtherInformation approach for this is cleaner and easier
745 to work with in proxies and the like. This facility can be used in
746 yaz-client using new command setscan which takes a result set as first
747 argument, start position (APT) as second.
749 Changed decoding of SRU XML packed records to deal with servers that
750 have recordData with XML data with multiple root nodes. Also make
751 comparison for recordPacking case insensitive. Again, one server
752 returns "XML" where others return "xml".
754 For SRU responses allow Content-Type application/xml as well as text/xml.
758 Fixed bug in character set conversion of BER strings. Bug introduced
763 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
765 For OID class, use oid_class consistently.
767 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
770 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
771 character set for bibliographic information interchange". By Giannis Kosmas.
773 Added documentation on new OID API.
777 Changes to generic frontend server interface: added new member
778 'query_charset' for bend_initrequest structure. A backend init handler
779 should set this member to its native character set for query terms.
780 When defined, the frontend server logic will announce this character set
781 to a client if the negotiationModel bit is set by the client. All server
782 implementors are encouraged to specify this. If a backend server does not
783 specify this a warning is issued using yaz_log(YLOG_WARN,..).
785 Added CCL utility to remove terms (stop words) from resulting RPN
786 tree. This is handled by functions with prefix ccl_stop_words_ .
788 New ZOOM C option, "rpnCharset", which allows client-side conversion of
789 terms in RPN queries.
791 Clean-up the CCL API. Moved some internal structures from ccl.h to
792 private header cclp.h. Changed ccl_parser_create so that a Bibset must
793 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
794 This is replaced by ccl_parser_find_str which takes a string instead.
796 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
797 libyaz.la is the core of YAZ except the generic frontend server and
798 does not depend on POSIX threads anymore. libyaz_server.la is the
799 generic frontend server facilities and uses POSIX thread functionality
800 if available. The libyaz.la no longer depends on POSIX threads because
801 the number of global structures is limited. NMEM no longer re-uses blocks
802 between threads ; it simply free's memory immediately but allocates in
803 "large" chunks as usual. We don't expect any performance penalties
804 because of this. The yaz_log system is still using a global log_level so
805 caution must be taken when modifying it with yaz_log_init_.. +
806 yaz_log_mask_str. This, however, should not cause any trouble because
807 these functions are called during initialization of application code
808 anyway. `yaz-config --libs server` returns libs for server applications;
809 `yaz-config --libs` returns libs for non-server applications.
811 New OID database - with public definitions in oid_db.h. Removed old OID
812 database including the head oid.h and definitions such as enum oid_value
813 and struct oident. The new OID database uses the same string names as
814 before but the 'protocol' is gone. There are now only two representations
815 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
816 converts from string to OID; functions with prefix yaz_oid_to_string
817 converts the other way.
819 Change to emit_term() in CQL-to-PQF query translation: when a term has
820 the /regexp relation modifier, do not process it for leading and
821 trailing "^" and "*", which have quite different meanings in regular
824 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
825 write handlers no longer carries a 'last' parameter. This will make
826 yaz_iconv flush "less" characters. A flush is performed by call to
827 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
829 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
830 removed, because function yaz_query_to_wrbuf does the same.
832 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
833 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
835 Deprecated MARC utility functions removed.
837 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
840 Branch split: YAZ_2_1_55_branch
842 --- 2.1.54 2007/03/16
844 Fix to ZOOM-C so that transparent reconnection is properly handled on
845 connections that are in asynchronous mode.
847 Fixed compilation on OpenBSD 4.0.
849 Large strings in GRS-1 records are now properly displayed in yaz-client.
851 Added character conversion support for "advancegreek"; based on patch from
854 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
855 sequence is met. Before the error was not set so it would be unknown.
857 Adjust yaz-marcdump MARC reader so that it skips until record separator
860 --- 2.1.52 2007/03/07
862 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
863 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
864 fd_set structure used as a bitmask for the FDs to be selected on.
866 Using ACX_PTHREAD macro to check for POSIX threads.
868 Fixed have-vsnprintf check.
870 --- 2.1.50 2007/02/23
872 Fixes for configure on BSD. Bug #900.
874 Added snprintf/vsnprintf wrappers for systems that don't have
875 limits (heavens forbid).
877 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
878 created before all previous tasks were completed and removed from the
879 task queue, the new task could be removed by a mistake.
881 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
883 Implemented pass-through CQL-to-PQF conversions. Bug #861.
885 Fixed bug #832: Problem with MARC/charset in yaz-client.
887 Fixed bug #668: save command line history for yaz-client.
889 Fixed bug #830: pkg-config support.
891 --- 2.1.48 2007/01/23
893 Extended ZOOM result set options with two options that may be read by
894 a client: resultSetStatus and presentStatus with values as specified for
896 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
898 Fixed bug #827: Using SSL fails on Debian etch.
900 Fixed bug #826: Weird looking chars for set of MARC records.
902 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
903 that is treated as an ItemOrder with itemRequest being an XML document
904 external. The value of "doc" is the content.
906 Extended the GFS search facility. New member of bend_search_rr
907 'estimated_hit_count' signals that hits is known to be an estmate
908 (higher or lower than real hit count). New member 'partial_resultset'
909 signals that the search was partial (hit count is lower or equal than
910 real hit count). For Z39.50, the information is stored in resultSetStatus
911 member of SearchResponse APDU. For SRU, the information is signalled
912 via SRU diagnostic 59: "Result set created with valid partial results
915 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
917 --- 2.1.46 2007/01/13
919 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
921 Added ZOOM_connection_peek_event.
923 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
924 the following new functions:
925 ZOOM_event_nonblock, ZOOM_connection_process,
926 ZOOM_connection_get_{socket,mask,timeout},
927 ZOOM_connection_fire_event_{timeout,socket}.
928 The existing blocking event handler, ZOOM_event, is a wrapper for the
929 + blocking ZOOM_event_sys_{poll,select}.
931 Implemented function ccl_xml_config which parses XML version of CCL
932 configuration (bug #798).
934 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
936 Added timings utility (yaz/timing.h)
938 --- 2.1.44 2007/01/03
940 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
943 Fixed bug #779: Rotation of apdu.log fails.
945 Fixed for character set conversions:
946 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
947 Honor G1 set in MARC-8 decoding.
949 --- 2.1.42 2006/12/17
951 Fixed bug #775: char conversion does not handle Alternative UTF-8
954 Implemented function yaz_marc_read_line which parses MARC line format
955 records. There is a wealth of formats out there. So far, this function
956 reads line records produced by yaz_marc_write_line.
958 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
959 more generic and easier to remember(!) options: -i format and -o format
960 which specifies input format and output format respectively - where
961 format is one of "marc", "marcxml", "line", "marcxchange".
963 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
964 does not print anything except warnings for records.
966 For yaz-marcdump, added support for MARC split into files (-s) with a given
969 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
970 spec, at http://www.loc.gov/standards/sru/record-update/
971 This has changed the binary layout of the following structs:
972 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
973 bend_update_rr . Patch by Ko van der Sloot.
975 Added GFS utility function bend_assoc_is_alive which returns 1 if
976 association is still alive (client is connected); 0 otherwise (client
977 closed connection). This allows busy servers to stop working for
980 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
981 been a separate piece of software. This version of ziffy has been modified
982 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
984 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
986 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
987 Client code may now interrogate options such as "init_opt_sort" to
988 find out whether the server claims to support various options.
990 --- 2.1.40 2006/11/27
992 Added utilities yaz_{set,get}_esn to set/get element set name from
995 Removed the build of libyazthread.la. The libyaz.so is the threaded version
996 of YAZ and has been so since YAZ 2.1.10.
998 Implemented ZOOM_record_error which returns error information for
999 record (surrogate diagnostic).
1001 --- 2.1.38 2006/10/31
1003 Updates for SRU Update by Ko van der Sloot:
1004 1. Changed name from "operation" to "action"
1005 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1006 versions in the code, marked as 'backward compatible'.
1007 3. Added diagnostics for SRU Update.
1009 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1011 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1013 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1015 For GFS, fixed problem with SRU diagnostic 'First record position out of
1016 range' being issued for 0 hits.
1018 zoomtst10 part of Windows Build.
1020 --- 2.1.36 2006/10/13
1022 Implemented yaz_filepath_comp which splits a path into file path
1023 components (required by Zebra 2.0.3+).
1025 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1026 BSD inspired license until now so this should not have any real impact on
1027 anybody. See http://www.opensource.org/licenses/bsd-license.php
1029 Fixed bug #687: Missing log lines.
1031 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1034 Fixed bug #689: SRU diagnostics to be added.
1036 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1037 whether a connection is idle (no more work do do).
1039 --- 2.1.34 2006/10/04
1041 Change type of optval from long to int for invocation of setsockopt with
1042 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1044 Added support for specifying the max log file size for the Generic
1045 Frontend Server. The size is given with option -r.
1047 --- 2.1.32 2006/09/21
1049 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1051 --- 2.1.30 2006/09/17
1053 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1056 Fixed bug in Generic Frontend Server that could cause a server to stop
1057 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1059 For the generic frontend server, the maximum record size is used as maximum
1060 size of incoming packages (SRU + Z39.50). The value until was previously
1061 only used in Z39.50 Init negotiation and, later, in a session controlled
1062 sizes of records returned. This is controlled using -k option. It can be
1063 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1065 --- 2.1.28 2006/09/04
1067 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1070 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1072 New option for yaz-marcdump -lpos=value which allows setting a portion
1073 of MARC header to a certain value.
1075 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1077 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1078 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1080 --- 2.1.26 2006/08/15
1082 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1085 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1087 --- 2.1.24 2006/08/08
1089 Fixed MARC ISO2709 encoding routines to deal with character set
1092 Minor changes to GFS logging. Database included in search request log
1095 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1096 cached/multiple records.
1098 Shared libraries are built by default on Unix+configure.
1100 Changed cql2pqf transformation to use a different evaluation order. The
1101 new order is: always, relation, structure, position, truncation, index
1102 and relationModifier. Old order was: always, relation, relationModifier,
1103 structure, index, position, truncation. Note that the the latter ones
1104 override former ones for identical attributes.. The new scheme means that
1105 it is possible to override any existing attribute with a relationModifier.
1106 And also that it is possible to override everything for the index rule
1107 (except the ones listed in relationModifier). No order is perfect but this
1108 one, we believe, covers more real cases.. The "always" should have been
1109 called "default", since the attributes there can be overridden with all
1112 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1113 compilation phase, but also for yaz-config --cflags output. This allows
1114 us to have public headers with Libxml2 stuff in them . It should also,
1115 eventually, make Libxml2 checks redundant in packages using YAZ, such
1118 --- 2.1.22 2006/06/15
1120 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1121 stored in uri, message and details.. Previously diagnostics were stored
1122 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1123 compatibility.. but he's probably the only one affected, so.
1125 Added support for CCL, compiled on the client side, in ZOOM-C. This
1126 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1127 input; the resulting query objects can be used for for searching with
1128 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1130 YAZ' configure searches for OpenSSL by default.
1132 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1133 SL_CTX_use_certificate_file. See
1134 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1135 for more info. Thanks to Ko van der Sloot.
1137 --- 2.1.20 2006/06/02
1139 Bug #600: SRU GET, POST support for yaz-client. Introduced
1140 command 'sru' which selects method SOAP/GET/POST.
1142 Allow missingValueAction to be specified for the sortspec string -
1143 function yaz_sort_spec. By default, the missing value action is null.
1144 Use ! to specify "abort". Use = followed by stringvalue to specify default
1147 Ensured that Present-handler (if defined) is called in GFS before any call to
1148 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1149 searchRetrieve requests.
1151 Documentation for YAZ is now based on the Docbook XML/XSLT using
1152 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1153 is no longer depending on jade/openjade or docbook-to-man scripts.
1154 PDF is no longer part of the distribution - but can optionally be
1155 made using DSSSL/jadetex or FOP.
1157 Added retrieval handling support in Generic Frontend Server to support
1158 conversion between MARC/XML as well as XSLTtransforms. See
1159 etc/yazgfs.xml for an example.
1161 Added Authentication support to Generic Frontend Server in SRU
1162 mode. Authentication using HTTP Basic is supported, as is the use
1163 of 'x-username' and 'x-password' parameters in the request itself.
1165 Added support for a new character set MARC8s identical to MARC8 except
1166 that it converts combined characters to single Unicode characters in the
1167 Latin-1 range (when possible).
1169 --- 2.1.18 2006/04/24
1171 ASN.1 compiler 0.4: generates brief Doxygen file header for
1172 generated .h/.c files.
1174 Utility yaz_iconv now supports conversion to MARC-8.
1176 New facilities for the MARC module. The reading - and writing of
1177 content are separate methods for the yaz_marc_t handle. The following
1178 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1179 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1180 format). Write functions have prefix yaz_marc_write_.. The existing
1181 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1182 available. Removed support for OAI-MARC and simplexml (not the
1183 simplexml from PHP5).
1185 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1186 to be returned for this connection.
1188 --- 2.1.16 2006/03/31
1190 Allow multiple languages and charsets to be specified with
1191 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1192 negcharset iso-8859-1,utf-8
1194 Translation of proximity nodes from CQL into PQF now works.
1196 Moved to automake 1.8, 1.9.
1198 Added function yaz_log_set_handler which allows a log handler to be
1199 installed. This handler will be called for all log messages. Output
1200 to file is also produced; but that can be disabled by passing NULL
1201 fname to yaz_log_init_file.
1203 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1205 For SRW (including GFS), accept application/soap+xml as content-type
1208 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1209 produces NO stylesheet reference even if a default stylesheet is specified
1212 --- 2.1.14 2006/03/14
1214 Updated Windows package to include yazd.dll + yazd.lib for the
1215 Development component.
1217 If the environment variable YAZ_LOG is set, then it is used as a
1218 string indicating the default level of logging to use if not
1219 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1220 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1221 used as before. So, for example, to omit warnings from YAZ logging,
1222 export YAZ_LOG=-warn
1224 cql_transform() now map structure and other attributes before indexes,
1225 so that index-specific structures and other attributes can override
1226 defaults. So now a combination of mapping specifications such as:
1228 index.dc.date = 1=date-modified 4=5
1229 does the right thing.
1231 cql_transform() now also respects the "always" mapping specification,
1232 which establishes an initial set of attributes to be used for all
1233 terms except where overridden by more specific attributes associated
1234 with the index, relation or modifier.
1236 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1237 which mode to use; one of "post", "get" or "soap" (SRW, default).
1239 Fixes for yaz_iconv routines: changed trie-based character set conversions
1240 to use only non-negative values for bit fields due to Sun's C compiler not
1241 supporting negative values.
1243 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1244 sequences where not read correctly. Fix by Rustam Usmanov.
1246 Updated win/makefile to use options, settings which makes things
1247 compile with VS C 2005.
1249 --- 2.1.12 2006/02/01
1251 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1253 In ZOOM socket code, use select instead of poll on MacOSX.
1255 ZOOM-C now support client-side compilation of CQL into RPN that is
1256 sent to the server, enabling CQL to be used against all Z39.50
1257 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1258 ZOOM_query object, and submit it using ZOOM_connection_search().
1259 The CQL-to-RPN translation uses a configuration file, the name of
1260 which must be specified in the Connection's "cqlfile" option.
1262 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1263 function, which takes as its start-term parameter a ZOOM_query object
1264 (which may have had either CQL or RPN set into it).
1267 --- 2.1.10 2005/11/29
1269 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1270 GFS to support this as well. Backend handler, bend_srw_update, does the
1271 update work. Code contributed by Ko van der Sloot.
1273 Allow retrieval of Search Result-1 information in ZOOM by the use of
1274 options that are attached to a result set. ZOOM documentation updated
1277 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1278 UTF-8 conversion. Patch by Raj Patel.
1280 Added option -m to GFS to control formatting of timestamps in log file.
1282 Added 'exit' as synonym for 'quit' in yaz-client
1284 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1285 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1286 for the new members. Patch by Ko van der Sloot.
1288 Added support for SRU POST. It is supported for content-type
1289 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1291 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1292 Instead make the library libyaz.la multi-threaded. Threading as a whole
1293 can still be disabled by configure option --disable-threads. Previosly,
1294 with older GLIBCs there were problems with MT libs under Apache. This
1295 has now been fixed a long time ago.
1297 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1300 CQL module modified to be case insensitive for relations/indexes/operations.
1302 Fixed bug in CQL transform code: incorrect value relationModifieder
1305 Added 'show all' command for yaz-client which retrieves all results
1308 Added new yaz-client, xmles, which takes a (private) OID and
1309 a document to be sent as an extended service request.
1311 Describe new yaz-client commands wait_response and set_auto_wait.
1313 Increase TCP/IP listener backlog from 3 (which I am guessing was
1314 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1315 that the socket will queue as many incoming connections as it's able
1316 to handle ongoing connections. In other words, it will never now
1317 refuse a connection that it would be able to handle merely because
1318 it's not got around to accepting() enough of the pending connections
1319 yet. This is the behaviour anyway under Linux, where the listen()
1320 argument is ignored; but not under BSD and on systems such as
1321 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1322 YAZ-based servers should now be uniform across operating systems in
1325 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1326 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1327 This allows yaz-marcdump to read large MARC batches (>2 GB).
1329 Modified all YAZ source files - except the source which is auto-generated
1330 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1333 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1334 corresponding to the existing *_setl() function. These allow option
1335 values containing arbitrary valuues.
1337 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1338 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1339 except that it returns an indicator of whether or not the sort
1340 criterion was accepted (0 for OK, -1 for invalid).
1342 --- 2.1.8 2005/06/07
1344 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1345 MARC output rather than returning "new" buffer.
1347 yaz-client warns about unknown init options.
1349 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1351 --- 2.1.6 2005/05/24
1353 Added support for SRW sort in Generic Frontend Server. Patch
1354 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1355 sortKeys - or NULL if none is provided.
1357 Fixed bug #307: It was impossible to specify indefinite/no timeout
1358 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1361 Added support for multiple languages and charsets to be specified in
1362 ZOOM. Each charset/language is separated by a blank. If negotiation is
1363 in effect in init-response, Option
1364 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1365 Code based on patch by Vasiliy Osadchuk.
1367 Fixed bug #306: infinite recursion that occurred when calling
1368 yaz_log_level_init as the first call (before other log level or
1371 Fixed bug in scan handling in front end server: if preferred-Position-In-
1372 Response was non-present, a NULL pointer referece was performed.
1374 --- 2.1.4 2005/04/26
1376 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1377 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1378 now defined for all those error codes. So instead of putting 109 in
1379 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1380 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1382 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1385 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1387 Program yaz-client now exits and produces an error message if multiple
1388 Z39.50 servers are specified on the command line (none or one allowed
1391 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1394 --- 2.1.2 2005/03/16
1396 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1398 Fixed bug #272: Preserve spacing for CCL terms.
1400 --- 2.1.0 2005/03/14
1402 Added support for virtual hosts and multiple backend servers for
1403 the YAZ frontend server. The configution is XML based and
1404 support specificition of CQL to RPN mappings and explain information.
1405 See section "Virtual Hosts" in the YAZ manual.
1407 Extended OPAC display utility. OPAC display utility renders
1408 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1409 to supplement yaz_marc_decode_wrbuf.
1411 Fixed a bug in MARC decoder that could caused it to crash for some
1412 invalid MARC records. More diagnostics and warnings where added in
1413 XML output (warnings, etc are stored in comments).
1415 --- 2.0.34 2005/02/08
1417 Fixes for UNIX domain sockets. Bug #261.
1419 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1421 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1422 Added yaz_marc_subfield_str which defines subfield lead string which is
1423 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1424 yaz_marc_endline_str which defines end of fields string used in
1425 YAZ_MARC_LINE format. Default string is newline.
1427 Experimental support for MarcXChange. This format can be produced
1428 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1429 http://www.bs.dk/standards/MarcXchange.xsd
1431 Added yaz-client commands scansize that sets maximum number of
1432 entries to be returned by scan.
1434 --- 2.0.32 2005/01/11
1436 Added support for SRW scan in yaz-client and Generic Frontend Server.
1438 * Added whereInList member to SRW Scan Term.
1440 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1442 Fixed NMEM system to return aligned blocks on the smallest boundaries
1443 that are suitably aligned for all possible types on the particular
1444 architecture YAZ is being built for.
1446 --- 2.0.30 2005/01/04
1448 Fixed numerious warnings that was issued with newer versions of GCC.
1450 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1451 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1454 Make YAZ Generic Frontend Server slightly faster.
1456 Enhance (and reduce) logging for Generic Frontend Server.
1458 Revert YAZ log system so that it flushes every write operation
1459 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1461 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1462 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1463 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1464 will effectively disable old definitions.
1466 --- 2.0.28 2004/11/09
1468 Added yaz_log_time_format which specifies log format using
1471 Added yaz_log_module_level which returns mask for a module. Value
1472 is non-zero mask a if module is enabled; zero if disabled.
1474 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1475 in include/yaz/cql.h.
1477 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1479 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1481 Fixed bug #172: RPM builds does not enable SSL.
1483 Doxyfile.in part of dist. Doxyfile generated by configure.
1485 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1486 are given and the corresponding component does not exist.
1488 Extend CCL documentation in YAZ reference. Describe r=r.
1490 --- 2.0.26 2004/10/01
1492 Fixed MARC->MARCXML conversion to properly deal with
1493 fields, subfields, indicators having non-ASCII characters.
1495 Fixed MARC->MARCXML conversion so that ASCII control characters
1496 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1499 Added YAZ GFS support for conversion from Z39.50 surrogate
1500 diagnostics to SRW surrogate diagnostics.
1502 Bug fix: YAZ GFS did not return schema in explainResponse.
1504 --- 2.0.25 2004/09/30
1506 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1507 now converts recordSchema to elementSetName as well as schema URI.
1509 Fixed bug in COMSTACK that prevented HTTP request packages from being
1512 --- 2.0.24 2004/09/29
1514 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1515 does not require white-space before and after the dash in a range, e.g.
1516 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1519 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1520 due to new GCC removing "redundant" code.
1522 Added yaz-client commands scanpos and scanstep that sets preferred
1523 position and step-size for scan.
1525 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1527 Added CCL utility ccl_qual_buf which parses one or more CCL
1528 spec lines in a buffer.
1530 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1531 of name and value - ignoring empty lines and comments.
1533 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1535 Added odr_get_element_path which returns current element path for an
1536 ODR handle. This utility is useful in error handling or user-defined
1539 Added ODR_PRINT utility odr_set_stream which is is a more generic
1540 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1541 to a write function and pointer to close function. The close function - if
1542 non-NULL - will be called during odr_destroy.
1544 Fixed bug in CCL parser where truncation char was not removed from
1545 right side when truncation=both was in effect.
1547 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1550 --- 2.0.23 2004/08/11
1552 Fix buffer overrun in CQL parser when dealing with proximity (%).
1554 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1555 to UTF-8/UCS conversion is now only based on codetables.xml.
1557 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1559 --- 2.0.22 2004/08/06
1561 Add support for more "commit changes" in ZOOM (uses Extended Services).
1563 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1566 Yet another small fix for configure of SSL.
1568 --- 2.0.21 2004/05/14
1570 Fix SSL libs for configure when --with-openssl=DIR is given.
1572 --- 2.0.20 2004/05/10
1574 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1576 SSL comstack now uses yaz.pem certificate file on server side
1577 by default. Certificate filename can be configured by calling
1578 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1580 Fix bug regarding multiple calls to ZOOM_connection_connect.
1582 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1584 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1585 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1587 ZOOM now allows inspection of X509 peer certificate for verification.
1588 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1590 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1591 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1592 as "modular" but it simplifies things.
1594 Added cs_get_peer_certificate to that returns peer X509 PEM.
1596 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1597 NULL if SSL is unavailable.
1599 Documentation about MARC decoding tools.
1601 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1603 --- 2.0.19 2004/03/30
1605 Rename CHANGELOG to NEWS to follow GNU style packing.
1607 Fix bug with missing initialization of member in init_diagnostics.
1608 This bug affects threaded version of GFS server.
1610 --- 2.0.18 2004/03/20
1612 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1615 Ensure zlib.dll is packed with Windows install.
1617 --- 2.0.17 2004/03/17
1619 Fix encoding of xsd:string to use text instead of CDATA.
1621 Fix endless loop in CQL parser with unbalanced ".
1623 Use a more compact way to store MARC-8 conversion tables.
1625 --- 2.0.16 2004/03/16 Debian only
1627 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1630 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1635 --- 2.0.15 2004/03/01
1637 Another fix for decoding of XML packed records.
1639 --- 2.0.14 2004/02/25
1641 Fixes for Chunked encoding. White space not ignored after length spec.
1643 Update NS and use default NS for SRW diagnostic elements.
1645 --- 2.0.13 2004/02/23
1647 Implement ZOOM_resultset_cache_reset which resets record cache.
1649 Implement ZOOM_resultset_sort which sorts a result set.
1651 Implement chunked HTTP transfer.
1653 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1655 --- 2.0.12 2004/02/16
1657 Added member 'schema' to bend_explain_rr structure so that backend
1658 can specify explain record identifier. Defaults to Zeerex 2.0.
1660 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1662 --- 2.0.11 2004/02/16
1664 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1667 Added init command for yaz-client which sends "extra" init request.
1669 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1670 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1672 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1674 Make ZOOM error code for "invalid query".
1676 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1678 --- 2.0.10 2004/02/05
1680 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1683 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1685 Added option -p <file> to make Generic Frontend Server to write PID file.
1687 Added option -D to put Generic Frontend Server in background on its own.
1689 Make ZOOM C recognize option "password". If unset, "pass" is used
1690 (for backwards compatibility).
1692 Fixed a bug in Generic Frontend Server that could make it crash if a
1693 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1696 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1697 Must be issued before open, in order to be in effect.
1699 --- 2.0.9-6 2004/01/12 Debian/Windows
1701 Make the SRU server more picky WRT unknown params, etc.
1703 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1705 New YAZ client command, options, that sets Z39.50 options.
1707 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1708 options from a string of tokens (one token for each option bit).
1710 Update SRW diagnostic code messages.
1712 --- 2.0.9-5 2004/01/07 Debian/Windows
1714 Handle user defined stylesheet for SRW/SRU.
1716 --- 2.0.9-4 2004/01/06 Debian/Windows
1718 Fix bug in decoding of Content-Length.
1720 --- 2.0.9-3 2004/01/06 Debian/Windows
1722 Fix a bug with decoding of XML packed records.
1724 --- 2.0.9-2 2004/01/05 Debian only
1726 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1728 Fix bug in SRW/SRU diagnostics decoding.
1730 --- 2.0.9 2004/01/05
1732 Fixed bug in Generic Frontend Server which could drop records exceeding
1733 preferred message size. Reported and fixed by Irina Dijour.
1735 Fixed calculation of package size for structured records in Generic
1736 Frontend Server. Reported and fixed by Irina Dijour.
1738 Fixed namespace for SRW/SRU diagnostics.
1740 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1742 --- 2.0.8 2003/12/22
1744 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1745 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1748 CQL changes to reflect recent changes to the specification:
1749 * Documentation talks about context sets instead of index sets.
1750 * Documentation talks about indexes instead of qualifiers.
1751 * The CQL-to-PQF transformer's configuration file now uses
1752 "index.set.name = <attributes>" instead of the old form
1753 "qualifier.set.name = <attributes>". (Both forms are still
1754 understood but the latter is deprecated.)
1755 * CQL terms with no explicit index specified are now interpreted as
1756 cql.serverChoice instead of srw.serverChoice (which of course
1757 behaves exactly the same.)
1759 --- 2.0.7 2003/12/16
1761 MARC conversion can now generate ISO2709 output in another
1762 character set. yaz-marcdump uses this facility if you invoke it
1765 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1766 functions from there can be used from C++.
1768 --- 2.0.6 2003/12/04
1770 Frontend server now transfers memory from decoded packages to stream
1773 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1774 references to show up.
1776 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1777 the ZOOM Abstract API. The older names for the same options are still
1778 also supported for the benefit of old applications.
1780 ZOOM-C supports "implementationId" and "implementationVersion" options
1781 to go along with "implementationName". These allow the user code to
1782 specify identification strings to be sent to servers.
1783 Add OID for the new ExtLite attribute set.
1785 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1786 as requested/supplid by Ere Maijala <ere@atp.fi>
1788 For generic frontend server, reverse the order of
1789 "toolkit-supplied / application-supplied" strings sent as implementationId,
1790 Name and Version. Also, remove the spaces around the slash. This brings
1791 the GFS in line with the behaviour of ZOOM-C on the client side.
1793 Add function ZOOM_scanset_display_term.
1795 yaz-client shows scan displayTerm if present.
1797 Utility yaz-iconv is now installed by default along with the man page
1800 Extend configure check for OpenSSL to use pkg-config where available (such
1803 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1804 server to specify uid/gid/mask for socket using the format
1805 unix:[user=uid,][group=gid,][umask=mask,]file=path
1806 If file= is omitted the existing format is assumed, e.g.
1808 in which case the mask is 0666 (rw for everybody).
1810 Major restructure of YAZ source. All source in libyaz is in src directory.
1811 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1812 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1814 Added man page for utility yaz-marcdump (used to be called marcdump).
1815 yaz-marcdump is installed by 'make install'.
1817 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1818 of incoming package failed.
1820 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1822 Change prototype of odr_perror: add const to message string.
1824 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1826 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1827 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1828 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1829 DNS lookup. There should not be any compatibility problems with this
1830 assuming that blocking=1 or 0 is used.
1832 Fix bad reference in UNIX comstack in function cs_addrstr.
1834 Fix for compilation on AIX.
1836 The generic front-end server (server/seshigh.c) now supports returning
1837 Init diagnostics to the client in User-information-field, in
1838 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1841 --- 2.0.4 2003/09/04
1843 Allow any CQL relation (not just all,any,exact,scr).
1845 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1846 that features the same UI.
1848 Implemented command update0 in YAZ client which is equivalent to
1849 update but uses old of Ext Update ASN.1.
1851 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1852 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1853 Previously no OID was used for this info.
1855 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1856 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1857 returns 'malformed search term' otherwise.
1859 SortResponse member resultCount now set to NULL in sort handler of
1862 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1865 Add three new utility functions for translating OIDs between various
1866 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1867 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1868 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1869 char *oid_to_dotstring(const int *oid, char *oidbuf);
1870 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1872 Reverted modifications for ES Update definition for z_IU0Update
1873 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1874 is back to YAZ 2.0.2.
1876 String value attributes for CCL parser.
1878 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1879 which their FirstSearch server returns in Init responses, sometimes
1880 carrying useful diagnostic information when Init fails. This has the
1881 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1882 "z39.50/oclcui.asn", where its definition is somewhat different from
1883 what OCLC document on their web-site, as required to interoperate with
1886 Support for anonymous authentication in yaz-client. Use the command
1889 * Fix the OID of the Index Data-local "admin" Extended Service from
1890 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1891 the 1000, which indicates a locally-defined OID, was a mistake.
1893 --- 2.0.3 2003/06/20
1895 Fix CCL directive @case handling so that it affects string match for
1896 both CCL keywords and qualifiers.
1898 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1899 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1900 Decoder has been updated with ASN.1 changes as listed in
1901 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1902 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1903 z_IUUpdate, remains unchanged.
1905 ZOOM_record_get may now return a record in a specific character set.
1906 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1907 "from" is the character set of record as returned by target. "to" is
1908 the character set to be returned. If omitted, "to" is UTF-8.
1910 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1912 New ODR utility, odr_getelement, which returns name of element for
1913 which encoding/decoding failed.
1915 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1916 in cases where a required element was omitted.
1918 Bug fix: some MARC8 sequences were not converted.
1920 New ZOOM option "step" which specifies number of records to be
1921 retrieved in one chunk. Used in conjunction with "start" and "count".
1923 SRW support for yaz-client. Use scheme http: to use it, e.g.
1926 yaz-client no longer does (un)intelligent character set conversions
1927 by default. Can be enabled with charset and marc_charset commands.
1929 xmalloc trace fix for 64-bit systems such as DEC alpha.
1931 Solaris 2.6 compile fix.
1933 New function, cql_strerror() translates SRW error codes, as returned
1934 by cql_transform_error(), into human-readable English strings. Used
1935 in yaz-client diagnostics when appropriate.
1937 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1938 converts it into a type-1 query which is sent to the server. This
1939 makes CQL available for use with all Z-servers, as opposed to the tiny
1940 minority that can handle CQL queries themselves.
1942 --- 2.0.2 2003/04/28
1944 New Debian package layout similar to the Redhat Package layout.
1946 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1947 and search result respectively.
1949 --- 2.0.1 2003/04/25
1951 Redhat package is now several packages: libyaz (runtime libraries),
1952 libyaz-devel (development and documentation, and yaz (utility programs).
1953 Package spec file by Morten Bogeskov.
1955 New member 'schema' in struct bend_fetch_rr which the name of requested
1956 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1957 handler MAY set this to reflect the schema of the returned record.
1959 New member 'display_term' in struct scan_entry. GFS now sets member entries
1960 and allocates scan entries to be filled by user scan handler. In previous
1961 version, entries member was allocated by the scan handler. That still works,
1962 but the GFS will ignore member display_term - assuming it was NOT set by
1963 the handler. The fact that the GFS now allocates the entries both allows
1964 for new members and makes a scan handler easier to write.
1966 Fix CQL lex buffer overflow.
1968 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1969 SRU default recordPacking is string.
1971 SRU protocol support for frontend server.
1973 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1975 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1977 Added scan for the ZOOM shell (zoomsh).
1981 * String Identifers for Schemas (Amendment 5).
1982 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1983 Old definition for schema
1984 Odr_oid *schema; /* OPT */
1989 Z_InternationalString *uri;
1990 #define Z_Schema_oid 1
1991 #define Z_Schema_uri 2
1994 * resultCount parameter to Sort Response (Amendment 1).
1995 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1997 Support for SRW 1.0 over HTTP. This is an optional feature and
1998 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2001 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2002 on the same port. SRW SearchRetrieveRequests are mapped
2003 to bend_init,bend_search,bend_fetch,bend_close.
2005 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2007 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2008 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2010 ZOOM connections are SRW based if schem http is used for hostname
2011 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2012 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2014 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2015 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2016 distance=n, order=true/false, relation=le, prox unit=word. If
2017 n is omitted, distance 1 is used.
2019 Fixed problem with C compiler include path in wrong order.
2021 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2022 on Solaris. Patch from Ko van der Sloot.
2024 New MARC decode API. All new functions operate on a yaz_marc_t
2025 handle. The most important new functions are: yaz_marc_create,
2026 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2027 decode and destroy respectively. Decoder can produce formats
2028 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2029 include/yaz/marcdisp.h.
2031 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2032 to UTF-8, UCS-32, wchar_t or Latin-1.
2034 * Prototypes for yaz_iconv_-functions moved to separate header
2035 include/yaz/yaz-iconv.h.
2037 Make a few private functions 'static' in unix.c. This prevents
2038 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2040 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2041 are set when Init Response is received.
2043 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2044 but returns diagnostic set as well.
2046 New function yaz_strerror which is a portable wrapper for
2047 strerror/strerror_r/GetLastMessage.
2049 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2050 is returned for MARC. If type is "oai", then OAI MARC is returned.
2052 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2055 --- 1.9.2 2002/11/26
2057 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2059 Fix bad race conditions on SIGTERM and terminate gracefully in
2062 Move retrieval (data1) module to Zebra since nobody seems to be
2065 Add GRS-1 render for ZOOM using same format as yaz-client.
2067 --- 1.9.1 2002/10/05
2069 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2071 Fix broken ESpec handling in data1 module.
2073 SGML reader parses comments and makes them part of the data1 tree.
2075 Added several type casts so that YAZ compiles as C++ code.
2077 ZOOM didn't handle PDU encoding failures properly.
2079 Added more Bib-1 diagnostics (approved extensions).
2081 GNU configure: better check for iconv.
2083 More portable use of accept, getpeername. Check for socklen_t. Use
2084 int/size_t if socklen_t is not defined.
2088 PQF parser rejects bad queries - including those with extra
2089 characters in them. PQF parser used to silently ignore that.
2090 Cleaner API for PQF added, which allows you to get detailed
2091 error information for bad queries (see yaz/pquery.h).
2093 Fixed bug in ZOOM_record_get for type "database".
2095 Implemented mini iconv library supporting conversions between
2096 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2098 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2100 --- 1.8.9 2002/08/20
2102 Fixed ZOOM C record cache so that preferredRecordSyntax and
2103 elementSetName is used to check for already fetched records.
2105 --- 1.8.8 2002/08/02
2107 Added three members in bend_initrequest structure to facilitate
2108 character set negotiation.
2110 Fixed a bug in frontend server that could cause indefinite
2111 loops under rare conditions.
2113 Revised character set utilities (charneg.h) so that encoding
2114 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2116 For PQF, directive @term <type> sets term type for Scan/Search.
2117 Here <type> is general, string, numeric, null. The term type
2118 is inherited - just like @attr.
2120 New call odr_set_charset that sets character set conversion for
2121 international-strings on a ODR stream. Prototype is:
2122 int odr_set_charset(ODR o, const char *to, const char *from);
2123 The InternationalString is still represented as C string in YAZ
2124 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2125 won't). On the protocol level, you can use any encoding.
2127 Support for UNIX sockets in ZOOM.
2129 Solaris recv sometimes returns errno == ENOENT. It is treated as
2130 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2132 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2133 both client and server. Code by Morten Bogeskov.
2135 --- 1.8.7 2002/05/22
2137 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2138 that they can be used directly from Visual Basic. You must recompile
2139 your windows APP if you're using ZOOM.
2141 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2142 Commands "lang" and "charset" sets language and character set respectively.
2143 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2144 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2146 Attributes from multiple CCL fields may be OR'ed rather than merged
2147 using directive "@field or". Fields are still merged by default -
2148 equivalent to "@field merge".
2150 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2153 Fixed bug in zget for parameter ExtendedServicesResponse.
2157 --- 1.8.6 2002/03/25
2159 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2161 Client displays USR.1:SearchResult-1 (hits per term).
2163 Additional Search Info for search in Generic Frontend Server.
2165 Fixed CCL parsing of "field=s".
2167 WIN32 installer - using the excellent NSIS software from nullsoft.
2169 Fixed CCL parsing of "field = - <number>".
2171 Added function yaz_marc_decode that decodes MARC for line mode
2172 display or XML (similar to that used by JZKit).
2174 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2175 Z39.50. But ISO/ILL was, however.
2177 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2178 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2180 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2181 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2183 --- 1.8.5 2002/02/03
2185 New YAZ client features: Command completion and new commands:
2186 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2187 Code provided by Jacob Poulsen.
2189 New call oid_trav, that visits all registered OIDs via callback.
2191 Function ZOOM_record_get now returns const char pointer rather than
2192 void pointer. It saves a lot of type casts.
2194 For YAZ client, command "auth" now allows you to set authentication
2195 in IdPass style. It is enabled when three tokens are given - order
2196 is user, group and password.
2198 Fix memory leaks in MARC record handling for ZOOM.
2200 New option for YAZ client, -k <kilobytes> that sets
2201 maximum record size. Similar to -k option for generic frontend
2202 server and yaz-ztest.
2204 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2206 Prefix query parser reports "fail" when bad attribute set is given.
2208 Fix in MARC decoder. Proximity logging. Fix for attribute set
2209 in scan handler for server. Patches by Shigeru Ishida.
2211 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2214 Configure option --with-openssl=<dir> now works when a directory is
2215 specified. Patch provided by Morten Bogeskov.
2217 New option for YAZ client, -u <auth>, that sets authentication.
2219 ZOOM fix: error information was sometimes "missing", since error
2220 was cleared/reset too when it shouldn't.
2222 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2224 --- 1.8.4 2002/01/04
2226 Scan for ZOOM API. New object ZOOM_scanset. New functions
2227 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2228 ZOOM_scanset_destroy.
2230 New ZOOM function, ZOOM_connection_last_event, that returns type
2231 of last event (such as "receive data", "send data", "apdu received",
2234 New ZOOM option, schema, that specifies schema for retrieval.
2236 New CCL feature. Qualifiers can be aliases for one or more
2237 other qualifiers (if more than one is given, OR is used).
2239 ZOOM uses named result sets if target supports it.
2241 Two new YAZ client commands: . (dot, which sources a script of YAZ
2242 client commands), and ! (to execute shell command.). Implemented
2245 Working on Debian packages.
2247 --- 1.8.3 2001/11/19
2249 YAZ client enables named result sets only if target supports it.
2251 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2253 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2254 with key="host" to get same result.
2256 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2257 Function Z3950_resultset_record(s) returns references to records
2258 "owned" by resultset. To become owner use Z3950_record_clone.
2260 Function z_ext_record handles Extended Services. Thanks to
2263 --- 1.8.2 2001/11/12
2265 CCL Parser fix: ignore token comma when dealing with and-lists.
2267 Documentation updates for COMSTACK.
2269 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2270 Changed prototype Z3950_records. For some functions, int parameters
2271 were changed to size_t.
2273 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2276 New MARC decode/display function, marc_display_exl, which properly rejects
2277 non-ISO2709 records. YAZ client uses it.
2279 --- 1.8.1 2001/10/29
2281 Fix bug: local attribute set wasn't set correctly in PQF strings.
2285 * Old Z39.50 codecs no longer supported.
2287 Added ZOOM C binding. See http://zoom.z3950.org/
2289 Renamed states for COMSTACKs to avoid confusion with events.
2291 Implemented cs_look and proper cs_rcvconnect.
2293 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2295 Configure detects POSIX threads on OpenBSD.
2297 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2298 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2300 When error is returned from present handler, non-surrogate diagnostic
2301 is returned in present response (and fetch handler is no longer called).
2303 * Minor adjustments to pquery parser (PQF). Token characters may be
2304 escaped by using backslash (C-style).
2306 PQF parser allows string attribute values to be specified. For @attr,
2307 non-numeric characters after the equal-sign are treated as strings
2308 (e.g. @attr 9=title).
2310 CCL trunction character may be defined (@truncation in file)
2312 * function zget_ExtendedServicesRequest sets waitAction to
2313 waitIfPossible (was wait).
2315 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2318 CCL operator names may be set in field definition files (CCL_bibset).
2319 See ccl/bib1 for an example.
2321 Fixes in ASN.1 compiler for C++ compatibility.
2323 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2324 and "op_or" to avoid conflict with C++.
2326 Fixed problem with GNU readline detection on Redhat 7.0.
2328 Added step-size for Scan backend handler.
2330 Fixed bug that made the frontend server crash when no attribute
2331 set was specified for scan.
2333 Front-end server automatically switches to original working directory
2334 when installed as an NT service. Previously -w had to be specified to
2337 Added extended attributes for retrieval module (data1), so that data1
2338 records carry d1_readXML/SGML attributes. d1_read also supports
2339 null-data rules ( <tag/>)
2341 On UNIX when POSIX threads are available, a separate library libyazthread
2342 is created. Programmers should link with that library and the yaz library
2343 when using threads. The reason for the split was that some applications
2344 on Linux, such as Apache, doesn't work well when using shared objects that
2347 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2348 (or any frontend server) in SSL mode by specifying ssl: followed by
2349 address. Only tested on UNIX.
2351 Added feature for CCL module. Virtual structure s=al or s=ol generates
2352 and-list and or-list respectively instead of phrase search.
2356 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2357 log_mask_str. This was done to avoid name conflicts with other libraries
2358 (such as other PHP extensions).
2360 Added raw OID member for preferred record syntax (request_format_raw)
2361 and returned record syntax (output_format_raw) for backend fetch method.
2363 Config file yaz-config now accepts options so that it returns specific
2364 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2366 Shared library support for UNIX using GNU libtool.
2368 * Modified backend interface. Request/Response struct's replaced by
2369 one read/write C struct. For example bend_fetchrequest and
2370 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2371 Every handler - even search has to be registered in bend_init
2372 handler. This means that the YAZ library no longer refers to
2373 external functions and it makes it possible to make the whole
2374 thing a single DLL/SO.
2376 Added Segment handler for backend server.
2378 Added Zmbol/Zebra administrative functions to YAZ client.
2380 Threaded frontend server on UNIX (when POSIX Threads are available).
2381 Starting the server with option -T enables multi-threading.
2385 Added configure option --enable-comp/disable-comp to control use
2386 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2387 located in sub directory asn.
2389 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2390 in ${exec_prefix}/bin along with the other programs yaz-client and
2393 GNU automake used to maintain makefiles.
2395 Added several OID's.
2397 Changed retrieval module so that we can load records with no abstract
2398 syntax defined. Tagpaths in these records are fully composed of string
2401 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2405 On UNIX, the generated makefile now supports a proper 'make install'.
2406 The prefix can be set via GNU configure to set the install location
2407 (default is /usr/local).
2409 * YAZ programs client and ztest were renamed to yaz-client and
2410 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2411 locations, such as /usr/bin,/usr/local/bin,etc.
2413 * YAZ Header files were moved from include to include/yaz. YAZ Header
2414 files are referred to as include <yaz/log.h> rather than <log.h>.
2415 The YAZ include path (-I ..) is therefore the same as before. Programmers
2416 should update their #include statements or use -Ipath/include/yaz
2417 instead. The main motivation for doing this change is that YAZ header files
2418 can be installed in "standard" locations /usr/include,/usr/local/include
2419 without introducing conflicts, since ALL YAZ header files are stored
2420 in subdirectory yaz (under /usr/include for example).
2422 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2423 rather than project/workspace files. We switched because project files
2424 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2427 Changed name of logging function, logf, to yaz_log, to prevent name
2428 clash with some math-log functions. The YAZ header log.h defines logf
2429 to yaz_log (#define) so there should be no incompatibilities by this
2432 Added bend_start/bend_stop handlers for server. These handler are
2433 called on start/stop of server. For windows they are called whenever
2434 a service is started/stopped.
2436 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2437 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2438 in util/yc.tcl. The auto-generated C code structures are, in a few
2439 cases, incompatible with the old decoders. There are differences in the
2440 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2441 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2442 The preprocessor variable ASN_COMPILED is defined when the compiled
2443 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2444 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2445 wish to use the old encoders/decoders you can specify --disable-yc
2448 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2449 version so that it supports both new - and old version of DB Update
2451 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2452 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2453 change. The name parameter can be set to 0 in which no name is specified
2454 for the construction. The macros odr_implicit and odr_explicit sets name
2455 parameter to zero for the construction involved. New macros
2456 odr_implicit_tag and odr_explicit_tag are similar to the others,
2457 except that a name parameter is added. For programmers' that don't use
2458 ODR they probably only need to change the call to z_APDU and z_External.
2460 Added access control facility by interfacing the TCP wrapper library.
2461 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2462 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2463 name of the daemon and enables the access control as specified in
2464 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2466 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2467 den Dool <H.M.vdnDool@kub.nl>.
2469 Added reference ID parameter to most functions in server API - refer
2470 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2472 Changed name of ccl library to libccl.a (was ccl.a).
2474 Fixed bug in decoder for Explain (Category TargetInfo).
2476 Added support for GNU readline in client. Thanks to Jacob Poulsen
2477 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2479 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2480 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2481 IMPLEMENTATION! This change was made to the development version before
2482 the ZIG decided to retract the amendment. If any users MUST be
2483 compatible with the original Update definition, PLEASE CONTACT US, and
2484 we will include a separate definition corresponding to the old Update
2485 ES. Note that because of the change to the ASN.1 of the
2486 TaskPackageRecordStructure we cannot define a single structure that
2487 will support both versions.
2489 * Added const modifier to buffer parameter for some ODR/BER encoding
2490 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2491 completeWAIS, odr_dumpBER.
2493 Fixed bug in client.c which caused a crash when a scanResponse didn't
2494 contain positionOfTerm.
2496 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2497 * will cause an error in a client if a non-YAZ target sends both a
2498 * list of Scan entries and non-surrogate diagnostics.
2500 Retrieval module enhancements. Tag sets may be typed in the reference
2501 to it. From the .abs-file the "tagset" directive takes a third optional
2502 integer type for the tag set referenced. From a .tag-file the "include"
2503 directive takes a third optional type as well. The old "type" directive
2504 in the tag set itself is still recognized but acts as the default type
2507 Backend interface change. Individual Scan terms returned from bend_scan
2508 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2509 in include/backend.h.
2511 Retrieval module enhancements. Multiple tag sets and attribute sets may
2512 be specified in abstract syntax specs. Revised the error/warning for
2513 logging messages reported by the retrieval module when reading the
2516 Object Identifier system (oid_..) changed. The API is backwards
2517 compatible but the oid-routines now allocates new OID's when needed.
2518 Raw OID's may be specified in oid_getvalbyname.
2520 YAZ now uses GNU configure to generate Makefile(s).
2522 * Minor changes in some of the member names of DeleteResultSetRequest and
2523 DeleteResultSetResponse. See include/proto.h.
2525 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2526 and added member 'languages' in TargetInfo (which was missing).
2528 Changed the way attribute sets are handled in the retrieval
2529 module. These are now cached, just like the abstract syntaxes
2532 Changed YAZ so that it links with compiled ASN.1.
2534 Added Explain-schema definitions and mapping routines. The following
2535 Explain categories have been implemented: AttributeDetails,
2536 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2538 Fixed minor bug in Windows version of Server Library.
2540 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2542 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2544 Added EXTERNAL: UNIverse Resource Report (non-standard).
2546 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2547 ENUMERATED and SET OF.
2549 * Added 'const' to some of the char pointer arguments for the
2550 functions, data1_read_node, data1_getelementbytagname,
2551 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2554 Fixed bug in data1_insert_taggeddata - the last_child member of
2555 parent wasn't initialised.
2557 * Changed data1_read_record and data1_read_node so that the supplied
2558 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2559 doesn't refer to any parts of the "SGML"-buffer.
2561 Fixed bug in server library (Windows version of statserv_remove).
2563 * Changed code so that it compiles as C++. The type definition
2564 of Odr_fun which is a member of Odr_arm was changed. The result is,
2565 that an explicit typecast is needed for the fun pointer when
2566 using Odr_arm - as in:
2567 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2569 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2571 Implemented the new structured date and time definition as approved
2572 by the ZIG. Added schemaId element to the specificTag in Espec-1
2573 (also approved at the last ZIG). Thanks to RVDM.
2575 Added some Object identifiers (RVDM).
2577 Changed the Update Extended Service (RVDM).
2579 Added command "refid" to client which specifies referenceId for
2580 the following requests.
2582 Implemented extended service handling for server. See ztest.c
2583 for an example as well as backend.h. New handlers are registerd
2584 in the Init handler.
2586 * Changed interface for sort in server.
2588 Added new members to statserv_options_block. It allows a server
2589 to read options from another source than just the command line. Thanks
2590 to Charles Woodfield.
2592 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2593 renamed to zboolean. Some C++ compilers complained about the name.
2595 Minor changes to gils.abs. Added index 's' (sort) on title
2596 and date/time-last-modified.
2598 --- 1.4pl2 1998/1/30
2600 Fixed bug in server library regarding inetd mode (-i). This bug
2601 was introduced by release 1.4.
2603 --- 1.4pl1 1998/1/29
2605 Added sort facility in client and backend server interface.
2607 Fixed problem with dependencies in Makefile(s).
2609 Fixed bugs for encoders/decoders of extended services and
2612 Implemented sub-tree feature for schemas. Sub-trees are
2613 referenced in *.abs-files. See explain.abs for an example
2614 of the use of this feature.
2616 Modified bib1.att; local attributes for ANY didn't include
2617 ANY itself (only affects use of the retrieval module).
2619 Fixed bug in plain SGML reader in function data1_read_node:
2620 tags with prefix "var" was incorrectly interpreted as variants.
2622 Added feature "sub-schemas" to enable references to - and definitions
2623 of - group of elements.
2625 * Removed member parent from type data1_element (in data1.h).
2627 Implemented function odr_nullval() that returns the value of
2630 * Removed member num_children from data1_node (in data1.h).
2632 Made NT service interface part of the server library. The
2633 function statserv_main uses the NT service when required and
2634 calls the statserv_start / statserv_close routines.
2636 Routine zget_SearchRequest and zget_PresentRequest fills
2637 resultSetName/Id member with "default" instead of "Default".
2639 Fixed memory leak in server. Request queue member wasn't freed.
2641 Fixed nmem_exit so that memory is freed.
2645 Revised the CCL parser utility to be thread safe.
2647 Added function, oid_ent_to_oid, to replace the function
2648 oid_getoidbyent, which is not thread safe.
2650 * Added nmem_init and nmem_exit to initialize and release
2651 NMEM resources. Function nmem_init should be called once in the
2652 initial thread before NMEM/ODR is used. statserv.c and client.c
2653 have been changed accordingly. The change was necessary to make
2654 NMEM thread safe. The NMEM memory pool is shared amongst threads
2655 in a process. Unix-based applications will still work fine without
2658 Added NT Services interface for the the Z39.50 (statserv) Server.
2659 Refer to the ztest.c source on the usage.
2661 Windows 95/NT port using MSVC5.0. Project files are included in the
2664 * Defined new 'global' handle for the retrieval (data1) system. The
2665 new handled, data1_handle, describes the state of the data1 system.
2666 This handle is passed as first argument to virtually all
2667 data1 related routines. The functions data1_create and data1_destroy
2668 creates and destroys a data1 handle respectively.
2670 Added ODR encode stream member to all backend request structures
2671 init, search, scan etc. This stream should be used to allocate all
2672 memory used for the response when thread safe operation is needed.
2674 Changed the comstack utility, cs_addstr, to be thread safe. The
2675 returned hostname string returned by the function is now part the
2678 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2679 function. The cs_straddr takes a COMSTACK handle as argument, so this
2680 function must be used after cs_create and before bind/connect.
2681 This function is thread safe.
2683 Moved test server to 'ztest' directory - generic server code still
2684 in 'server' directory.
2686 Made prefix query (pquery.c) utility thread safe.
2688 Added new function modifier YAZ_EXPORT to 'export' public DLL
2689 functions when using windows (see include/yconfig.h).
2691 Added definitions to the OID database (util/oid.c) (RVDM).
2693 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2695 Added call to ccl_rpn_delete in client program.
2697 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2698 release of RPN structure.
2700 Added support for C++, headers uses extern "C" for public definitions.
2701 With input from RVDM.
2703 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2704 Thanks to Ronald van der Meer (RVDM).
2706 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2708 Added support for private extensions to the OID database
2709 (oid_setprivateoids()). Thanks to RVDM.
2711 Added optional, physical ANY (key replication)
2713 Fixed null-reference problem in GRS-1 output filter.
2715 Proximity operator added to Prefix Query Format (PQF).
2717 In test client command "base" accepts multiple databases.
2719 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2723 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2725 Smallish bug-fixes in the new encoders/decoders (explain).
2727 Bug fixed in DeleteRequest.
2729 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2731 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2733 Added SOIF syntax (using private OID for now) to retrieval module and client.
2735 Added Update extended service.
2737 Added SearchResult-1 additional info structure.
2739 Added optional CCL (ISO8777) interpreter as separate module. Available
2742 --- 1.2 1996/6/10 (1st anniversary release)
2744 Added Summary record syntax. Lightly tested.
2746 Added OPAC record syntax. Untested.
2748 Added ResourceReport service encoders/decoders. Untested.
2750 Fixed bug in z_Unit - wrong tagging on unitSystem.
2752 Fixed bug in the DiagRecs decoder.
2754 Added options for max PDU size and session timeout to frontend-server.
2756 Added documentation of query-language parsers and other supporting utilities.
2758 [frontend-server] Added Attribute set to the bend_scanrequest API.
2760 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2761 surrogate diagnostics were generated.
2763 [retrieval] Allow multiple local values for attribute.
2765 [retrieval] Allow multiple attributes per element in .abs files. index type.
2767 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2769 --- 1.1pl2 1996/4/10
2771 Minor changes, mostly specific to Zebra's requirements (retrieval)
2775 Repaired bug in frontend server when running multiple listening
2776 endpoints in dynamic mode.
2778 z_External() now won't break if a known, ASN.1 value comes encapsulated
2779 in an octet-string. The value will pass through unmodified in an Odr_oct.
2781 Added a bit of code to the demo client to decode & display
2782 ASN.1-structured records represented in the octet-aligned branch of
2783 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2785 Added z_ext_getentbyref() to the ASN module. Doc updated.
2787 * Completed the SCAN definition in the ASN module. This may break SCAN
2788 code based on older YAZ-versions at compile-time. The fix is easy -
2791 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2792 under the SCAN definition. Remember to initialize this, server-people.
2794 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2795 that this does not extend to ODR and ASN.
2797 Comstack allows insertion of established socket (primarily for
2798 inetd-operation of servers). Doc updated.
2800 Front-end server can now start from the inetd in TCP mode. Doc
2803 --- 1.0pl4 1996/1/24
2807 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2808 the rank and record number.
2810 Adjustments to the frontend server.
2812 Fixed diagnostic BER dumper. It ignored the file argument.
2816 Various changes to retrieval module.
2818 Changed the union discriminators of the protocol files from enums to
2819 ints paired with #defines.
2821 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2824 *Changed operator in the RPN structure to 'roperator', again to avoid a
2827 Fixed problems in Explain decoders/encoders.
2829 --- 1.0pl2 1995/12/6
2831 Memory bug in log module fixed.
2833 --- 1.0pl1 1995/12/5
2835 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2837 Bug in Explain DatabaseInfo module fixed.
2839 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2843 The shift to v1.0 signals that we now consider the *core* functionality
2844 of YAZ reasonably stable (the core being more or less equivalent to
2845 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2846 tested (Explain not at all - though that will happen soonish).
2848 Minor changes to code to support Windows port.
2850 Various minor changes after we're getting to use GRS-1 & co. more.
2852 Added Espec-1 format.
2854 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2855 of the protocol and it cannot be selected when encoding (maps into 'string'
2856 when decoding). Needed to talk to some servers.
2858 Demo client can request simple element set names.
2860 Added Diagnostic Format encoders/decoders.
2862 Added simple Close handling to frontend server (no hooks for resource
2863 reporting yet), and demonstration client.
2865 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2867 --- 1.0b3 1995/08/24
2869 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2870 handled incorrectly when records were requested in the searchResponse. This
2871 will only affect you if you use the frontend-server.
2873 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2874 Test-client will ask for and print GRS1. Ztest will return dummy records
2877 Added Explain encoders/decoders to the service-level API. Untested.
2879 Added Extended Services: Item Order encoders and decoders to the Service-
2880 level API. Untested. We could use a recent copy of the pertinent bits
2881 of the ILL protocol to add those bits.
2883 Added diagnostic format 1 encoders/decoders to the service-level API.
2886 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2887 odr_cons.c, which causes a more correct output.
2889 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2890 was always set to 0 when no records were requested in the searchRequest.
2892 * Added better external-handling. This shouldn't harm old code that
2893 *encodes* externals. It can break code that looks for a
2894 'single-ASN1-type' representation, since those types that are known
2895 are now decoded immediately. Look at the SUTRS sample code in
2896 seshigh.c and client.c. Documentation updated.
2898 Handling of structured records in bend_fetchresponse. Length -1 marks
2899 structured record, type is deduced from format field.
2901 --- 1.0b2 1995/06/27
2902 Fairly quick maintenance release to add SUTRS support.
2904 Fixed handling of SUTRS records in the demonstration client.
2906 * Added format field to the bend_fetchrequest and bend_fetchresponce
2907 structures of the backend API (frontend server). When the record is
2908 returned, the value of the format field is mapped to an OID. The
2909 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2910 of the record. The special value VAL_NONE in the bend_request means
2911 that no specific format was requested by the client. Documentation
2912 updated accordingly. Test server (ztest) will return a fixed dummy
2913 SUTRS record if your client requests SUTRS.
2915 Documentation updated accordingly.
2917 You can now set external libraries and RANLIB support in the top-level
2921 First public release.
