1 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
2 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
3 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
4 peers on some Linux systems. However, in general that does not work
5 so YAZ can not rely on that to work. Debian changed behavior in this
6 respect from Debian lenny to Debian squeeze (still testing as of Oct
8 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
12 Fix yaz-config output: echo_source not set correctly by configure.
16 SOLR WebService support for yaz-client and ZOOM.
18 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
22 Z39.50 facet support. Facet specifications are passed for search in
23 other-information with ASN.1 as defined in facet.asn and OID
24 .10.1000.81.5 . Facets are expressed as an Attribute list as known
25 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
26 3 is limit (number of entries to get in response). yaz-ztest returns
27 dummy facets if a client asks for them.
31 CCL fixes: bug 2895 and bug 3539.
33 GR1-display: add comma in display - was removed by mistake in
36 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
38 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
42 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
43 result set from a connection. The result set will be on its own
44 thereafter; no operations on it will perform retrievals from a target.
45 Only cached copies are returned.
47 ZOOM C:fix case for HTTP servers responding with Connection:close.
48 Ensure that if there is a current task it is resumed (like fetching
49 more records in a result set) . Bug #3484.
51 PQF parser: use odr_atoi for Odr_int (not atoi)
53 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
54 values that contain any non-digits are treated as string attributes
55 (previously decoding only checked for leading character ([0-9]). PQF
56 encoding: attribute string values are not surrounded by double-quotes.
60 New utility for managing threads - thread_create.h.
62 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
63 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
64 but YAZ' implementation do.
66 Fixes for yaz_cond-functions on Windows 7.
68 DLL export more symbols.
70 zoomsh: show record do NOT render opac.
72 Remove *.la files from Debian and RPM packages.
76 Debian package libyaz-dev depends on libgnutls-dev again (was
77 removed in YAZ 4.0.6, but due to Libtool it is still needed
78 even though yaz-config do not list libgnutls libs).
80 ZOOM: Use only one WRBUF for returning string results for
81 ZOOM_resultset. Reduces memory usage for ZOOM in general.
83 ZOOM: ZOOM_connection do not use a shared pointer to
84 ZOOM_resultset after ZOOM_resultset is destructed by
85 user. Reverts to YAZ 4.0.4 behavior.
89 record-conv: fix problem with at least one XSL conversion -
90 due to probably incorrect usage of XML XSL documents.
94 Fix yaz-config for static mode and the use of SSL (gnutls).
98 Forward decl timeval struct in mutex.h and gettimeofday.h.
100 yaz-config: fix 'static' mode linking.
104 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
105 are wrappers for pthreads or Windows. For Windows these are put in
106 a separate DLL: yaz_cond4.
108 libyaz.la (whole source) is compiled with thread. If thread support
109 is enabled enabled, all source of YAZ is compiled with treading support.
110 This allows core utilities such as yaz_log to use thread facilities.
111 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
112 thread utilities. This commit moves mutex utilities (mutex.c) from
113 libyaz_server.la to libyaz.la.
115 yaz-json-parse displays leading text until error.
119 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
120 patch from Giannis Kosmas.
122 SRU: no longer URL encode SRU database. The URL for an SRU server is
123 a URL and such is alreeady encoded - at least when given with leading
124 http:// or https://. This reverts behavior to YAZ 3.0.50.
126 Support for new MARC XML notation TurboMARC which like MARCXML is a
127 complete representation of MARC/ISO2709.. This one, however, is more
128 compact and allows for faster processing with XSLT. TurboMARC can be
129 used in the marcdisp.h API, from the yaz-marcdump utility and from
132 yaz-ztest can be configured - via the database - to perform certain
133 delays when it performs operations search, present and single record
134 fetch. This allows testers to make yaz-ztest act as a real or even slow
135 Z39.50 server. Refer to the yaz-ztest man pages for details.
139 wrbuf_destroy allows NULL WRBUF passed to it.
141 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
143 Add ZOOM_connection_close.
145 No fixed size buffers for ZOOM shell - bug #3257.
147 tstodr: make it work on s390 platform.
149 New icu iterator-functions. The new icu_iter-functions makes it possible
150 to use ICU chains from many threads.
152 yaz-client: better syntax check for show command.
156 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
159 New simple local-file XML include facility which allows file glob-patterns.
160 Refer to yaz/xml_include.h.
162 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
165 ZOOM_record_get supports new parameter "format" which makes it format XML
168 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
169 JSONText in ECMA-262) is JSONValue, not JSONObject.
173 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
174 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
176 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
177 POSIX/Unix builds .so with major version 4.
179 Remove old LOG_-defines from log.h. They have been obsolete and
180 undefined by default for the last 5 years.
182 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
184 GFS: Remove socket (int *fd) from search_rr handler. The socket
185 descriptor ptr is a facility that allowed a search handler to supply
186 a socket which would serve as a callback - when search was complete.
187 This facility has now been in use for years.
189 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
190 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
191 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
192 returns 'const char *' rather than 'char *. The returned string is
193 read-only and should not be modified by applications. COMSTACK cs_close is
194 now a void function - it no longer returns int. No applications check for
195 the value and the implementations has always returned 0.
197 ZOOM: use size_t for scan hit counts and str size. Functions
198 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
199 occ (hit count) and len (string length) are now of type size_t pointer
200 rather than int pointer. This is to be able to represent large hit counts
201 and to also just to use the proper type for string length (strlen result).
203 New JSON parser. Refer to include/yaz/json.h .
205 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
206 Used to be int in some cases. Many wrbuf_-functions used to return an int
207 indicating some length.. These return values were never used. And so they
210 ODR: odr_malloc, odr_total now takes size_t for size.
212 clone_z_type: fix leak; occurred for encoding failures.
214 --- 3.0.52 2009/12/03
216 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
217 bug was introduced in 3.0.51.
219 --- 3.0.51 2009/12/02
221 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
223 tcpip comstack: fix leak for getaddrinfo.
225 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
226 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
227 Decoding of SRU "path" database is performed by private function
228 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
229 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
231 yaz-client: honor base command for SRU. Change when database setting
232 is applied for SRU and ensure it is kept when a connection is reset.
233 Change also the way errors are displayed or SRU (decoding of packages).
235 --- 3.0.50 2009/11/02
237 Add support for extra request / response data for SRU codecs and GFS.
238 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
239 for extra data response buffer and length. For the GFS, both request
240 and response data (XML) is carried in extra_args and extra_response_data
241 for the search handler. Patch by Ko van der Sloot.
243 ZOOM: For queries that cannot be converted to the specified rpnCharset,
244 ZOOM now returns a diagnostic on the client-side ('invalid query' /
245 10010). This fixes bug #2113.
247 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
248 cmdfile included a 'quit' command that would result in a memory violation.
250 --- 3.0.49 2009/10/01
252 Make a number of functions defined in xmlquery.c static. These have
253 never been declared in a public header file (yaz/xmlquery.h) and was
254 made public by mistake.
256 Improve speed of character conversions (iconv utilities). This makes
257 conversions from MARC-8 faster.
259 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
260 unless type desired is "raw". This will prevent type "xml" from
261 returning ISO2709 .. Which obviously can not be XML parsed.
263 Fix memory leak in ZOOM that would occur if option apdulog was used
264 on a re-used connection.
266 Frontend server logs HTTP requests.
268 Frontend server now sends Z39.50 close when it times out (sesssion has
269 been idle for too long). Versions 2.0.30 and earlier also sent close.
270 But due to a mistake this was disabled in all versions after that, i.e.
271 the server would just close the socket immediately.
273 yaz-client emits a better message when receiving an unrecognised
274 userInformationField.
276 Skip zero-length subfields when decoding ISO2709. This rare case happens
277 if a record has two FS characters in a sequence. Without this patch
278 there would be a reference beyond char array in using_code_len fragments
281 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
283 --- 3.0.48 2009/08/28
285 The show command offered by the zoomsh command now takes a 3d optional
286 parameter type which is what is passed to ZOOM_record. If the type
287 argument is omitted, "render" is used.
289 RPN to CQL conv may use USE string attributes (bug #2978).
291 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
293 --- 3.0.47 2009/07/08
295 Function yaz_xml2query allows a diagnostic element in the PQF XML
296 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
297 code and additional info respectively.
299 The BER BOOLEAN is now the integral type Odr_bool which still happens
300 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
301 typedef'd to Odr_int. This is still an integral 'int', but it may be
302 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
303 ASN-1 compiler as well as programs has been updated to use the new types.
305 --- 3.0.46 2009/06/08
307 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
308 only the bibliographic record was rendered. For type=opac, an OPAC
309 record is only returned if it is present.
311 iconv: small fix for encoding of advancegreek.
313 yaz-client: avoid double display of SRU/SRW records (bug #2798).
315 yaz-client: option auto_reconnect=on really reconnects.
317 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
319 server: avoid null ptr ref for for yaz_poll errors.
321 build: fix RPM build for RHEL 5.3.
323 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
325 --- 3.0.45 2009/03/31
327 Fixed bug #2709: TCP connect returns Invalid argument.
329 Fixed compilation for mingw.
331 Honor charset for raw records (ZOOM_record_get).
333 Fixed use of errno for threaded mode that was seen on Solaris 10.
335 Fixed argument passing with blanks in value for Windows Service.
337 Disable YAZ' own log rotate by default (no 1 GB limit).
338 The variable l_max_size which specifies the log file limit is set to 0
339 (DISABLED): This is due to the fact that YAZ is most often deployed using
340 logrotate. Also YAZ can not perform log rotate because of unsufficient
341 permissions (setuid).
343 --- 3.0.44 2009/02/17
345 List supported encodings in man page for yaz-iconv.
347 Fixed missing SSL libs for --libs output
349 Re-established OID record syntax application-xml. Nobody should use it
350 but we don't want to change soname because of this symbol being absent.
352 --- 3.0.42 2009/02/02
354 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
356 Added member named_result_sets for init handler struct for the GFS. This
357 allows a server to disable named result sets.
359 Removed OID record syntax application-xml.
361 Added support for rule-based transliterator for ICU wrapper of YAZ.
363 Fixed bug #1902: yaz-icu XML output.
365 Make YAZ checks Emacs friendly.
367 BITSTRING value shows value. Bug #2346.
369 ISO2709 decoding: skip control characters from indicator data.
371 Omit sort key by default in yaz-icu's output.
373 Allow combined single char options (again) for YAZ' options function.
375 Utility yaz-marcdump got option to display YAZ version (-V).
377 Allow YAZ to use ICU 3.4.
379 Added new ICU test case which illustrates removal of diacritics.
381 --- 3.0.41 2008/12/29
383 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
385 --- 3.0.40 2008/12/29
387 For configure, using option --without-xml2 also disables Libxslt/Libexslt
390 Fixed bug #2352: yaz-marcdump crashes for certain record.
392 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
394 Added support for Danmarc2 to UTF-8 conversion.
396 Added support for ISO5426 to UTF-8 conversion.
398 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
399 implementation version.
401 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
403 --- 3.0.38 2008/11/10
405 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
406 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
408 ZOOM C now interprets databaseName option for ZOOM connection as path
411 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
413 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
415 Dummy Libxml2 types no longer defined in headers of YAZ'.
417 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
420 --- 3.0.36 2008/09/26
422 Various ODR chapter fixes.
424 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
426 Added missing source for Windows compilation, mutex.c.
428 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
430 For SRU connections in ZOOM all records up to "count" are now fetched.
432 Fixed crash in generic frontend server (and yaz-ztest) which occurred
433 in Windows due to bad error handling for Libxml2.
435 Added facility for sending arbitrary records (ASN.1 any) using
436 ZOOM C's Extended service update. Patch by Sam Reynolds.
438 New options for ZOOM C's connection, logapdu which makes ZOOM log
441 --- 3.0.34 2008/06/18
443 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
445 --- 3.0.32 2008/06/12
447 Fixed memory violation that could occur when decoding UTF-8. This bug
448 was only present in 3.0.30 of YAZ.
450 --- 3.0.30 2008/06/06
452 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
453 GNU TLS is used by default (if found).
455 yaz-ztest returns OPAC records if a client asks for OPAC.
457 Improved speed of MARC-8 encoding.
459 Added support for lossy and loss-less MARC-8 encoding.
461 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
463 Added new Windows Service wrapper (sc).
465 yaz-client's itemorder command may now send a file.
467 Fixed yaz-marcdump to allow the use of NS prefix for record element.
469 Added new function yaz_log_xml_errors.
471 Allow (but warn) unknown XML attributes in MARCXML parsing.
473 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
475 The UTF-8 to MARC-8 conversion now uses a different set of characters
476 for Greek symbols. Bug #2120.
478 --- 3.0.26 2008/02/21
480 Added yaz_daemon (daemon.h).
482 Fixed bug #2068: pkg-config trouble
484 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
486 --- 3.0.24 2008/01/28
488 Document --with-xml2 option.
490 Added OPAC XML XSD (etc/opacxml.xsd).
492 Allow glob mask for name attribute in retrieval element for the
493 generic frontend server's retrieval facility.
495 Changed yaz_poll_poll to return yaz_poll_except for all returned events
496 except POLLIN/POLLOUT.
498 Fixed error handling in cs_listen. Bug #2037.
500 --- 3.0.22 2008/01/20
502 Fixed version in yaz/yaz-version.h.
504 Fixed bug #2027: Crash when closing connection.
506 Changed configure so that ICU support is only enabled if only ICU
507 and Libxml2 is available (because the ICU chain is XML based).
509 --- 3.0.20 2008/01/15
511 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
512 is built. Only this DLL depends on the ICU runtime.
514 yaz-ziffy is no longer part of YAZ. It is distributed separately by
515 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
517 Changed license of CCL module to 'Revised BSD'. After consultation with
518 remaining members of the original EUROPAGATE consortium, we are re-issuing
519 the CCL module without a separate license. The software was developed by
520 Index Data as part of a research project. The special license was included
521 to help feed usage information back to the project consortium to support
522 project evaluation. At this time, the project consortium has long-since
523 disbanded, and the majority of the original principals have retired. At the
524 same time, we have significantly modified the software during the following
525 years, to the point where very practically no original code remains. To
526 simplify re-use of the software, we have contacted those members of the
527 consortium who could be reached, and agreed to re-issue the module as a
528 proper part of the YAZ package.
530 Tcl scripts uses /usr/bin/tclsh as preferred shell.
532 CQL closer to being version 1.2 compliant. CQL also allows free-form
533 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
536 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
537 bug could make Extended services handling crash in the ZOOM layer. This
538 bug was only present in YAZ 3.0.18.
540 --- 3.0.18 2007/12/19
542 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
545 yaz-marcdump reads and writes collection wrapped records.
547 Handle OPAC for record conversion module.
549 Fixes for ICU wrapper.
551 Allow ICU libs to be controlled with --with-icu .
553 --- 3.0.16 2007/11/12
555 Added yaz_poll which is a wrapper for select/poll. When poll is available
556 and non-buggy, it is used, by yaz_poll . This allows more than 1024
557 sockets to be in use.
559 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
560 functionality through an XML based configuration (ICU chain). This system
561 is useful for search facilities such as Pazpar2 and Zebra that needs to
562 perform tokenization of indexed material. The ICU code in a separate
563 library libyaz3_icu.a.
565 Added HTTP tunnel facility for COMSTACK, bug #1752.
566 This is a facility that allows a Web proxy, such as squid, to tunnel
567 Z39.50 traffic. This facility is "transparent" to must applications
568 using YAZ. It's enabled by using pseudo transport connect: followed by
569 the proxy address, followed by command, then follwed by he regular
570 "virtual" addresss. For example,
571 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
573 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
575 --- 3.0.14 2007/09/21
577 Fixed bad memory reference in ZOOM_record - cuased by member not being
578 initialized. This was a problem only in YAZ 3.0.12.
580 Fixed bug in conversion from MARC to XML: Non-XML characters in control
581 fields were not removed.
583 Changed the way C code is generated from codetables.xml. Made a MARC-8
584 conversion trie for each characterSet section rather than codeTable.
585 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
586 of codetables.xml from Larry Dixson, LOC. Bug #1464.
588 --- 3.0.12 2007/09/12
590 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
591 from ZOOM_record_error).
593 ZOOM C function ZOOM_record_get returns record schema for type="schema".
595 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
597 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
599 Better SRW-to-Bib-1 diagnostic mapping.
601 ZOOM C and yaz-client announces SRU version 1.2 by default.
603 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
606 Fixed in yaz_sru_decode to allow other version than 1.1.
608 --- 3.0.10 2007/08/22
610 Added support for SRU scan for ZOOM.
612 Added support for the use of the older versions or Extended Service
613 Update in ZOOM. To faciliate this, an option "updateVersion" may be
614 set to the version , 1=first, 2=second, 3=third. The third version is
615 what ZOOM C has used so far. And that, obviously, is the default.
617 Added support for CCL queries in Z39.50 queries sent to the GFS (and
618 therefore in Zebra and in SimpleServer-based applications). The new
619 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
620 qualifier file used to transform incoming CCL queries into Type-1 RPN,
621 which is passed into the back-end search callback function.
623 Added support for HTTP Basic authentication in clients: the SRU/W
624 codec encodes the username/password elements of the PDU structure
625 appropriately, and these may be set using the "user" and "password"
626 options in ZOOM-C applications (the same options that are used for
627 Z39.50 authentication).
631 Fixed bug #1208: SSL appears to be broken in ZOOM.
633 Fixed bug #1206: Libxml2 include path weirdness.
635 Added oid_name_to_dotstring.
637 Allow elementSetName to be specified for ZOOM C record update.
639 Allow waitAction to be specified for ZOOM C based for Extended Services.
641 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
642 syntax OID. Bug introduced in YAZ 3 series.
644 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
648 Fixed bug #1157: yaz-client does not read .yazclientrc from current
649 directory. yaz-client now reads commands from file given by option -f
650 if specified; then tries to read .yazclientrc in current directory.
651 Failing that, it reads .yazclientrc from user's home directory.
653 Added support for correlationInfo Note and ID for Record Update via
656 Added yaz-client command querycharset which specifies character set for
657 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
658 (termListAndStartPoint).
660 Charset ISO5428:1984 is an alias for ISO5428-1984.
662 Implemented a way to perform scan in a result set using Z39.50. This
663 is achieved by attaching the result set name in the characterInfo
664 (type InternationalString) of OtherInformation in the Scan Request PDU.
665 The result set is identified in the otherinformation by the new OID:
666 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
667 This allows for scan in result set and faceted search . Zebra did some
668 of this in the APT term using attribute type 8 and value being result
669 set. Using the OtherInformation approach for this is cleaner and easier
670 to work with in proxies and the like. This facility can be used in
671 yaz-client using new command setscan which takes a result set as first
672 argument, start position (APT) as second.
674 Changed decoding of SRU XML packed records to deal with servers that
675 have recordData with XML data with multiple root nodes. Also make
676 comparison for recordPacking case insensitive. Again, one server
677 returns "XML" where others return "xml".
679 For SRU responses allow Content-Type application/xml as well as text/xml.
683 Fixed bug in character set conversion of BER strings. Bug introduced
688 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
690 For OID class, use oid_class consistently.
692 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
695 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
696 character set for bibliographic information interchange". By Giannis Kosmas.
698 Added documentation on new OID API.
702 Changes to generic frontend server interface: added new member
703 'query_charset' for bend_initrequest structure. A backend init handler
704 should set this member to its native character set for query terms.
705 When defined, the frontend server logic will announce this character set
706 to a client if the negotiationModel bit is set by the client. All server
707 implementors are encouraged to specify this. If a backend server does not
708 specify this a warning is issued using yaz_log(YLOG_WARN,..).
710 Added CCL utility to remove terms (stop words) from resulting RPN
711 tree. This is handled by functions with prefix ccl_stop_words_ .
713 New ZOOM C option, "rpnCharset", which allows client-side conversion of
714 terms in RPN queries.
716 Clean-up the CCL API. Moved some internal structures from ccl.h to
717 private header cclp.h. Changed ccl_parser_create so that a Bibset must
718 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
719 This is replaced by ccl_parser_find_str which takes a string instead.
721 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
722 libyaz.la is the core of YAZ except the generic frontend server and
723 does not depend on POSIX threads anymore. libyaz_server.la is the
724 generic frontend server facilities and uses POSIX thread functionality
725 if available. The libyaz.la no longer depends on POSIX threads because
726 the number of global structures is limited. NMEM no longer re-uses blocks
727 between threads ; it simply free's memory immediately but allocates in
728 "large" chunks as usual. We don't expect any performance penalties
729 because of this. The yaz_log system is still using a global log_level so
730 caution must be taken when modifying it with yaz_log_init_.. +
731 yaz_log_mask_str. This, however, should not cause any trouble because
732 these functions are called during initialization of application code
733 anyway. `yaz-config --libs server` returns libs for server applications;
734 `yaz-config --libs` returns libs for non-server applications.
736 New OID database - with public definitions in oid_db.h. Removed old OID
737 database including the head oid.h and definitions such as enum oid_value
738 and struct oident. The new OID database uses the same string names as
739 before but the 'protocol' is gone. There are now only two representations
740 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
741 converts from string to OID; functions with prefix yaz_oid_to_string
742 converts the other way.
744 Change to emit_term() in CQL-to-PQF query translation: when a term has
745 the /regexp relation modifier, do not process it for leading and
746 trailing "^" and "*", which have quite different meanings in regular
749 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
750 write handlers no longer carries a 'last' parameter. This will make
751 yaz_iconv flush "less" characters. A flush is performed by call to
752 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
754 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
755 removed, because function yaz_query_to_wrbuf does the same.
757 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
758 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
760 Deprecated MARC utility functions removed.
762 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
765 Branch split: YAZ_2_1_55_branch
767 --- 2.1.54 2007/03/16
769 Fix to ZOOM-C so that transparent reconnection is properly handled on
770 connections that are in asynchronous mode.
772 Fixed compilation on OpenBSD 4.0.
774 Large strings in GRS-1 records are now properly displayed in yaz-client.
776 Added character conversion support for "advancegreek"; based on patch from
779 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
780 sequence is met. Before the error was not set so it would be unknown.
782 Adjust yaz-marcdump MARC reader so that it skips until record separator
785 --- 2.1.52 2007/03/07
787 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
788 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
789 fd_set structure used as a bitmask for the FDs to be selected on.
791 Using ACX_PTHREAD macro to check for POSIX threads.
793 Fixed have-vsnprintf check.
795 --- 2.1.50 2007/02/23
797 Fixes for configure on BSD. Bug #900.
799 Added snprintf/vsnprintf wrappers for systems that don't have
800 limits (heavens forbid).
802 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
803 created before all previous tasks were completed and removed from the
804 task queue, the new task could be removed by a mistake.
806 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
808 Implemented pass-through CQL-to-PQF conversions. Bug #861.
810 Fixed bug #832: Problem with MARC/charset in yaz-client.
812 Fixed bug #668: save command line history for yaz-client.
814 Fixed bug #830: pkg-config support.
816 --- 2.1.48 2007/01/23
818 Extended ZOOM result set options with two options that may be read by
819 a client: resultSetStatus and presentStatus with values as specified for
821 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
823 Fixed bug #827: Using SSL fails on Debian etch.
825 Fixed bug #826: Weird looking chars for set of MARC records.
827 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
828 that is treated as an ItemOrder with itemRequest being an XML document
829 external. The value of "doc" is the content.
831 Extended the GFS search facility. New member of bend_search_rr
832 'estimated_hit_count' signals that hits is known to be an estmate
833 (higher or lower than real hit count). New member 'partial_resultset'
834 signals that the search was partial (hit count is lower or equal than
835 real hit count). For Z39.50, the information is stored in resultSetStatus
836 member of SearchResponse APDU. For SRU, the information is signalled
837 via SRU diagnostic 59: "Result set created with valid partial results
840 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
842 --- 2.1.46 2007/01/13
844 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
846 Added ZOOM_connection_peek_event.
848 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
849 the following new functions:
850 ZOOM_event_nonblock, ZOOM_connection_process,
851 ZOOM_connection_get_{socket,mask,timeout},
852 ZOOM_connection_fire_event_{timeout,socket}.
853 The existing blocking event handler, ZOOM_event, is a wrapper for the
854 + blocking ZOOM_event_sys_{poll,select}.
856 Implemented function ccl_xml_config which parses XML version of CCL
857 configuration (bug #798).
859 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
861 Added timings utility (yaz/timing.h)
863 --- 2.1.44 2007/01/03
865 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
868 Fixed bug #779: Rotation of apdu.log fails.
870 Fixed for character set conversions:
871 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
872 Honor G1 set in MARC-8 decoding.
874 --- 2.1.42 2006/12/17
876 Fixed bug #775: char conversion does not handle Alternative UTF-8
879 Implemented function yaz_marc_read_line which parses MARC line format
880 records. There is a wealth of formats out there. So far, this function
881 reads line records produced by yaz_marc_write_line.
883 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
884 more generic and easier to remember(!) options: -i format and -o format
885 which specifies input format and output format respectively - where
886 format is one of "marc", "marcxml", "line", "marcxchange".
888 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
889 does not print anything except warnings for records.
891 For yaz-marcdump, added support for MARC split into files (-s) with a given
894 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
895 spec, at http://www.loc.gov/standards/sru/record-update/
896 This has changed the binary layout of the following structs:
897 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
898 bend_update_rr . Patch by Ko van der Sloot.
900 Added GFS utility function bend_assoc_is_alive which returns 1 if
901 association is still alive (client is connected); 0 otherwise (client
902 closed connection). This allows busy servers to stop working for
905 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
906 been a separate piece of software. This version of ziffy has been modified
907 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
909 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
911 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
912 Client code may now interrogate options such as "init_opt_sort" to
913 find out whether the server claims to support various options.
915 --- 2.1.40 2006/11/27
917 Added utilities yaz_{set,get}_esn to set/get element set name from
920 Removed the build of libyazthread.la. The libyaz.so is the threaded version
921 of YAZ and has been so since YAZ 2.1.10.
923 Implemented ZOOM_record_error which returns error information for
924 record (surrogate diagnostic).
926 --- 2.1.38 2006/10/31
928 Updates for SRU Update by Ko van der Sloot:
929 1. Changed name from "operation" to "action"
930 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
931 versions in the code, marked as 'backward compatible'.
932 3. Added diagnostics for SRU Update.
934 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
936 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
938 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
940 For GFS, fixed problem with SRU diagnostic 'First record position out of
941 range' being issued for 0 hits.
943 zoomtst10 part of Windows Build.
945 --- 2.1.36 2006/10/13
947 Implemented yaz_filepath_comp which splits a path into file path
948 components (required by Zebra 2.0.3+).
950 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
951 BSD inspired license until now so this should not have any real impact on
952 anybody. See http://www.opensource.org/licenses/bsd-license.php
954 Fixed bug #687: Missing log lines.
956 Fixed bug #678: CQL to PQF translation does not preserve double-quote
959 Fixed bug #689: SRU diagnostics to be added.
961 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
962 whether a connection is idle (no more work do do).
964 --- 2.1.34 2006/10/04
966 Change type of optval from long to int for invocation of setsockopt with
967 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
969 Added support for specifying the max log file size for the Generic
970 Frontend Server. The size is given with option -r.
972 --- 2.1.32 2006/09/21
974 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
976 --- 2.1.30 2006/09/17
978 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
981 Fixed bug in Generic Frontend Server that could cause a server to stop
982 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
984 For the generic frontend server, the maximum record size is used as maximum
985 size of incoming packages (SRU + Z39.50). The value until was previously
986 only used in Z39.50 Init negotiation and, later, in a session controlled
987 sizes of records returned. This is controlled using -k option. It can be
988 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
990 --- 2.1.28 2006/09/04
992 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
995 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
997 New option for yaz-marcdump -lpos=value which allows setting a portion
998 of MARC header to a certain value.
1000 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1002 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1003 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1005 --- 2.1.26 2006/08/15
1007 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1010 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1012 --- 2.1.24 2006/08/08
1014 Fixed MARC ISO2709 encoding routines to deal with character set
1017 Minor changes to GFS logging. Database included in search request log
1020 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1021 cached/multiple records.
1023 Shared libraries are built by default on Unix+configure.
1025 Changed cql2pqf transformation to use a different evaluation order. The
1026 new order is: always, relation, structure, position, truncation, index
1027 and relationModifier. Old order was: always, relation, relationModifier,
1028 structure, index, position, truncation. Note that the the latter ones
1029 override former ones for identical attributes.. The new scheme means that
1030 it is possible to override any existing attribute with a relationModifier.
1031 And also that it is possible to override everything for the index rule
1032 (except the ones listed in relationModifier). No order is perfect but this
1033 one, we believe, covers more real cases.. The "always" should have been
1034 called "default", since the attributes there can be overridden with all
1037 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1038 compilation phase, but also for yaz-config --cflags output. This allows
1039 us to have public headers with Libxml2 stuff in them . It should also,
1040 eventually, make Libxml2 checks redundant in packages using YAZ, such
1043 --- 2.1.22 2006/06/15
1045 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1046 stored in uri, message and details.. Previously diagnostics were stored
1047 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1048 compatibility.. but he's probably the only one affected, so.
1050 Added support for CCL, compiled on the client side, in ZOOM-C. This
1051 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1052 input; the resulting query objects can be used for for searching with
1053 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1055 YAZ' configure searches for OpenSSL by default.
1057 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1058 SL_CTX_use_certificate_file. See
1059 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1060 for more info. Thanks to Ko van der Sloot.
1062 --- 2.1.20 2006/06/02
1064 Bug #600: SRU GET, POST support for yaz-client. Introduced
1065 command 'sru' which selects method SOAP/GET/POST.
1067 Allow missingValueAction to be specified for the sortspec string -
1068 function yaz_sort_spec. By default, the missing value action is null.
1069 Use ! to specify "abort". Use = followed by stringvalue to specify default
1072 Ensured that Present-handler (if defined) is called in GFS before any call to
1073 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1074 searchRetrieve requests.
1076 Documentation for YAZ is now based on the Docbook XML/XSLT using
1077 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1078 is no longer depending on jade/openjade or docbook-to-man scripts.
1079 PDF is no longer part of the distribution - but can optionally be
1080 made using DSSSL/jadetex or FOP.
1082 Added retrieval handling support in Generic Frontend Server to support
1083 conversion between MARC/XML as well as XSLTtransforms. See
1084 etc/yazgfs.xml for an example.
1086 Added Authentication support to Generic Frontend Server in SRU
1087 mode. Authentication using HTTP Basic is supported, as is the use
1088 of 'x-username' and 'x-password' parameters in the request itself.
1090 Added support for a new character set MARC8s identical to MARC8 except
1091 that it converts combined characters to single Unicode characters in the
1092 Latin-1 range (when possible).
1094 --- 2.1.18 2006/04/24
1096 ASN.1 compiler 0.4: generates brief Doxygen file header for
1097 generated .h/.c files.
1099 Utility yaz_iconv now supports conversion to MARC-8.
1101 New facilities for the MARC module. The reading - and writing of
1102 content are separate methods for the yaz_marc_t handle. The following
1103 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1104 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1105 format). Write functions have prefix yaz_marc_write_.. The existing
1106 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1107 available. Removed support for OAI-MARC and simplexml (not the
1108 simplexml from PHP5).
1110 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1111 to be returned for this connection.
1113 --- 2.1.16 2006/03/31
1115 Allow multiple languages and charsets to be specified with
1116 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1117 negcharset iso-8859-1,utf-8
1119 Translation of proximity nodes from CQL into PQF now works.
1121 Moved to automake 1.8, 1.9.
1123 Added function yaz_log_set_handler which allows a log handler to be
1124 installed. This handler will be called for all log messages. Output
1125 to file is also produced; but that can be disabled by passing NULL
1126 fname to yaz_log_init_file.
1128 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1130 For SRW (including GFS), accept application/soap+xml as content-type
1133 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1134 produces NO stylesheet reference even if a default stylesheet is specified
1137 --- 2.1.14 2006/03/14
1139 Updated Windows package to include yazd.dll + yazd.lib for the
1140 Development component.
1142 If the environment variable YAZ_LOG is set, then it is used as a
1143 string indicating the default level of logging to use if not
1144 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1145 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1146 used as before. So, for example, to omit warnings from YAZ logging,
1147 export YAZ_LOG=-warn
1149 cql_transform() now map structure and other attributes before indexes,
1150 so that index-specific structures and other attributes can override
1151 defaults. So now a combination of mapping specifications such as:
1153 index.dc.date = 1=date-modified 4=5
1154 does the right thing.
1156 cql_transform() now also respects the "always" mapping specification,
1157 which establishes an initial set of attributes to be used for all
1158 terms except where overridden by more specific attributes associated
1159 with the index, relation or modifier.
1161 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1162 which mode to use; one of "post", "get" or "soap" (SRW, default).
1164 Fixes for yaz_iconv routines: changed trie-based character set conversions
1165 to use only non-negative values for bit fields due to Sun's C compiler not
1166 supporting negative values.
1168 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1169 sequences where not read correctly. Fix by Rustam Usmanov.
1171 Updated win/makefile to use options, settings which makes things
1172 compile with VS C 2005.
1174 --- 2.1.12 2006/02/01
1176 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1178 In ZOOM socket code, use select instead of poll on MacOSX.
1180 ZOOM-C now support client-side compilation of CQL into RPN that is
1181 sent to the server, enabling CQL to be used against all Z39.50
1182 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1183 ZOOM_query object, and submit it using ZOOM_connection_search().
1184 The CQL-to-RPN translation uses a configuration file, the name of
1185 which must be specified in the Connection's "cqlfile" option.
1187 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1188 function, which takes as its start-term parameter a ZOOM_query object
1189 (which may have had either CQL or RPN set into it).
1192 --- 2.1.10 2005/11/29
1194 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1195 GFS to support this as well. Backend handler, bend_srw_update, does the
1196 update work. Code contributed by Ko van der Sloot.
1198 Allow retrieval of Search Result-1 information in ZOOM by the use of
1199 options that are attached to a result set. ZOOM documentation updated
1202 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1203 UTF-8 conversion. Patch by Raj Patel.
1205 Added option -m to GFS to control formatting of timestamps in log file.
1207 Added 'exit' as synonym for 'quit' in yaz-client
1209 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1210 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1211 for the new members. Patch by Ko van der Sloot.
1213 Added support for SRU POST. It is supported for content-type
1214 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1216 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1217 Instead make the library libyaz.la multi-threaded. Threading as a whole
1218 can still be disabled by configure option --disable-threads. Previosly,
1219 with older GLIBCs there were problems with MT libs under Apache. This
1220 has now been fixed a long time ago.
1222 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1225 CQL module modified to be case insensitive for relations/indexes/operations.
1227 Fixed bug in CQL transform code: incorrect value relationModifieder
1230 Added 'show all' command for yaz-client which retrieves all results
1233 Added new yaz-client, xmles, which takes a (private) OID and
1234 a document to be sent as an extended service request.
1236 Describe new yaz-client commands wait_response and set_auto_wait.
1238 Increase TCP/IP listener backlog from 3 (which I am guessing was
1239 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1240 that the socket will queue as many incoming connections as it's able
1241 to handle ongoing connections. In other words, it will never now
1242 refuse a connection that it would be able to handle merely because
1243 it's not got around to accepting() enough of the pending connections
1244 yet. This is the behaviour anyway under Linux, where the listen()
1245 argument is ignored; but not under BSD and on systems such as
1246 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1247 YAZ-based servers should now be uniform across operating systems in
1250 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1251 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1252 This allows yaz-marcdump to read large MARC batches (>2 GB).
1254 Modified all YAZ source files - except the source which is auto-generated
1255 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1258 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1259 corresponding to the existing *_setl() function. These allow option
1260 values containing arbitrary valuues.
1262 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1263 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1264 except that it returns an indicator of whether or not the sort
1265 criterion was accepted (0 for OK, -1 for invalid).
1267 --- 2.1.8 2005/06/07
1269 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1270 MARC output rather than returning "new" buffer.
1272 yaz-client warns about unknown init options.
1274 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1276 --- 2.1.6 2005/05/24
1278 Added support for SRW sort in Generic Frontend Server. Patch
1279 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1280 sortKeys - or NULL if none is provided.
1282 Fixed bug #307: It was impossible to specify indefinite/no timeout
1283 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1286 Added support for multiple languages and charsets to be specified in
1287 ZOOM. Each charset/language is separated by a blank. If negotiation is
1288 in effect in init-response, Option
1289 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1290 Code based on patch by Vasiliy Osadchuk.
1292 Fixed bug #306: infinite recursion that occurred when calling
1293 yaz_log_level_init as the first call (before other log level or
1296 Fixed bug in scan handling in front end server: if preferred-Position-In-
1297 Response was non-present, a NULL pointer referece was performed.
1299 --- 2.1.4 2005/04/26
1301 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1302 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1303 now defined for all those error codes. So instead of putting 109 in
1304 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1305 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1307 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1310 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1312 Program yaz-client now exits and produces an error message if multiple
1313 Z39.50 servers are specified on the command line (none or one allowed
1316 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1319 --- 2.1.2 2005/03/16
1321 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1323 Fixed bug #272: Preserve spacing for CCL terms.
1325 --- 2.1.0 2005/03/14
1327 Added support for virtual hosts and multiple backend servers for
1328 the YAZ frontend server. The configution is XML based and
1329 support specificition of CQL to RPN mappings and explain information.
1330 See section "Virtual Hosts" in the YAZ manual.
1332 Extended OPAC display utility. OPAC display utility renders
1333 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1334 to supplement yaz_marc_decode_wrbuf.
1336 Fixed a bug in MARC decoder that could caused it to crash for some
1337 invalid MARC records. More diagnostics and warnings where added in
1338 XML output (warnings, etc are stored in comments).
1340 --- 2.0.34 2005/02/08
1342 Fixes for UNIX domain sockets. Bug #261.
1344 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1346 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1347 Added yaz_marc_subfield_str which defines subfield lead string which is
1348 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1349 yaz_marc_endline_str which defines end of fields string used in
1350 YAZ_MARC_LINE format. Default string is newline.
1352 Experimental support for MarcXChange. This format can be produced
1353 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1354 http://www.bs.dk/standards/MarcXchange.xsd
1356 Added yaz-client commands scansize that sets maximum number of
1357 entries to be returned by scan.
1359 --- 2.0.32 2005/01/11
1361 Added support for SRW scan in yaz-client and Generic Frontend Server.
1363 * Added whereInList member to SRW Scan Term.
1365 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1367 Fixed NMEM system to return aligned blocks on the smallest boundaries
1368 that are suitably aligned for all possible types on the particular
1369 architecture YAZ is being built for.
1371 --- 2.0.30 2005/01/04
1373 Fixed numerious warnings that was issued with newer versions of GCC.
1375 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1376 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1379 Make YAZ Generic Frontend Server slightly faster.
1381 Enhance (and reduce) logging for Generic Frontend Server.
1383 Revert YAZ log system so that it flushes every write operation
1384 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1386 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1387 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1388 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1389 will effectively disable old definitions.
1391 --- 2.0.28 2004/11/09
1393 Added yaz_log_time_format which specifies log format using
1396 Added yaz_log_module_level which returns mask for a module. Value
1397 is non-zero mask a if module is enabled; zero if disabled.
1399 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1400 in include/yaz/cql.h.
1402 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1404 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1406 Fixed bug #172: RPM builds does not enable SSL.
1408 Doxyfile.in part of dist. Doxyfile generated by configure.
1410 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1411 are given and the corresponding component does not exist.
1413 Extend CCL documentation in YAZ reference. Describe r=r.
1415 --- 2.0.26 2004/10/01
1417 Fixed MARC->MARCXML conversion to properly deal with
1418 fields, subfields, indicators having non-ASCII characters.
1420 Fixed MARC->MARCXML conversion so that ASCII control characters
1421 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1424 Added YAZ GFS support for conversion from Z39.50 surrogate
1425 diagnostics to SRW surrogate diagnostics.
1427 Bug fix: YAZ GFS did not return schema in explainResponse.
1429 --- 2.0.25 2004/09/30
1431 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1432 now converts recordSchema to elementSetName as well as schema URI.
1434 Fixed bug in COMSTACK that prevented HTTP request packages from being
1437 --- 2.0.24 2004/09/29
1439 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1440 does not require white-space before and after the dash in a range, e.g.
1441 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1444 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1445 due to new GCC removing "redundant" code.
1447 Added yaz-client commands scanpos and scanstep that sets preferred
1448 position and step-size for scan.
1450 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1452 Added CCL utility ccl_qual_buf which parses one or more CCL
1453 spec lines in a buffer.
1455 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1456 of name and value - ignoring empty lines and comments.
1458 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1460 Added odr_get_element_path which returns current element path for an
1461 ODR handle. This utility is useful in error handling or user-defined
1464 Added ODR_PRINT utility odr_set_stream which is is a more generic
1465 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1466 to a write function and pointer to close function. The close function - if
1467 non-NULL - will be called during odr_destroy.
1469 Fixed bug in CCL parser where truncation char was not removed from
1470 right side when truncation=both was in effect.
1472 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1475 --- 2.0.23 2004/08/11
1477 Fix buffer overrun in CQL parser when dealing with proximity (%).
1479 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1480 to UTF-8/UCS conversion is now only based on codetables.xml.
1482 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1484 --- 2.0.22 2004/08/06
1486 Add support for more "commit changes" in ZOOM (uses Extended Services).
1488 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1491 Yet another small fix for configure of SSL.
1493 --- 2.0.21 2004/05/14
1495 Fix SSL libs for configure when --with-openssl=DIR is given.
1497 --- 2.0.20 2004/05/10
1499 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1501 SSL comstack now uses yaz.pem certificate file on server side
1502 by default. Certificate filename can be configured by calling
1503 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1505 Fix bug regarding multiple calls to ZOOM_connection_connect.
1507 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1509 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1510 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1512 ZOOM now allows inspection of X509 peer certificate for verification.
1513 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1515 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1516 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1517 as "modular" but it simplifies things.
1519 Added cs_get_peer_certificate to that returns peer X509 PEM.
1521 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1522 NULL if SSL is unavailable.
1524 Documentation about MARC decoding tools.
1526 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1528 --- 2.0.19 2004/03/30
1530 Rename CHANGELOG to NEWS to follow GNU style packing.
1532 Fix bug with missing initialization of member in init_diagnostics.
1533 This bug affects threaded version of GFS server.
1535 --- 2.0.18 2004/03/20
1537 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1540 Ensure zlib.dll is packed with Windows install.
1542 --- 2.0.17 2004/03/17
1544 Fix encoding of xsd:string to use text instead of CDATA.
1546 Fix endless loop in CQL parser with unbalanced ".
1548 Use a more compact way to store MARC-8 conversion tables.
1550 --- 2.0.16 2004/03/16 Debian only
1552 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1555 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1560 --- 2.0.15 2004/03/01
1562 Another fix for decoding of XML packed records.
1564 --- 2.0.14 2004/02/25
1566 Fixes for Chunked encoding. White space not ignored after length spec.
1568 Update NS and use default NS for SRW diagnostic elements.
1570 --- 2.0.13 2004/02/23
1572 Implement ZOOM_resultset_cache_reset which resets record cache.
1574 Implement ZOOM_resultset_sort which sorts a result set.
1576 Implement chunked HTTP transfer.
1578 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1580 --- 2.0.12 2004/02/16
1582 Added member 'schema' to bend_explain_rr structure so that backend
1583 can specify explain record identifier. Defaults to Zeerex 2.0.
1585 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1587 --- 2.0.11 2004/02/16
1589 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1592 Added init command for yaz-client which sends "extra" init request.
1594 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1595 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1597 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1599 Make ZOOM error code for "invalid query".
1601 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1603 --- 2.0.10 2004/02/05
1605 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1608 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1610 Added option -p <file> to make Generic Frontend Server to write PID file.
1612 Added option -D to put Generic Frontend Server in background on its own.
1614 Make ZOOM C recognize option "password". If unset, "pass" is used
1615 (for backwards compatibility).
1617 Fixed a bug in Generic Frontend Server that could make it crash if a
1618 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1621 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1622 Must be issued before open, in order to be in effect.
1624 --- 2.0.9-6 2004/01/12 Debian/Windows
1626 Make the SRU server more picky WRT unknown params, etc.
1628 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1630 New YAZ client command, options, that sets Z39.50 options.
1632 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1633 options from a string of tokens (one token for each option bit).
1635 Update SRW diagnostic code messages.
1637 --- 2.0.9-5 2004/01/07 Debian/Windows
1639 Handle user defined stylesheet for SRW/SRU.
1641 --- 2.0.9-4 2004/01/06 Debian/Windows
1643 Fix bug in decoding of Content-Length.
1645 --- 2.0.9-3 2004/01/06 Debian/Windows
1647 Fix a bug with decoding of XML packed records.
1649 --- 2.0.9-2 2004/01/05 Debian only
1651 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1653 Fix bug in SRW/SRU diagnostics decoding.
1655 --- 2.0.9 2004/01/05
1657 Fixed bug in Generic Frontend Server which could drop records exceeding
1658 preferred message size. Reported and fixed by Irina Dijour.
1660 Fixed calculation of package size for structured records in Generic
1661 Frontend Server. Reported and fixed by Irina Dijour.
1663 Fixed namespace for SRW/SRU diagnostics.
1665 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1667 --- 2.0.8 2003/12/22
1669 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1670 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1673 CQL changes to reflect recent changes to the specification:
1674 * Documentation talks about context sets instead of index sets.
1675 * Documentation talks about indexes instead of qualifiers.
1676 * The CQL-to-PQF transformer's configuration file now uses
1677 "index.set.name = <attributes>" instead of the old form
1678 "qualifier.set.name = <attributes>". (Both forms are still
1679 understood but the latter is deprecated.)
1680 * CQL terms with no explicit index specified are now interpreted as
1681 cql.serverChoice instead of srw.serverChoice (which of course
1682 behaves exactly the same.)
1684 --- 2.0.7 2003/12/16
1686 MARC conversion can now generate ISO2709 output in another
1687 character set. yaz-marcdump uses this facility if you invoke it
1690 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1691 functions from there can be used from C++.
1693 --- 2.0.6 2003/12/04
1695 Frontend server now transfers memory from decoded packages to stream
1698 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1699 references to show up.
1701 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1702 the ZOOM Abstract API. The older names for the same options are still
1703 also supported for the benefit of old applications.
1705 ZOOM-C supports "implementationId" and "implementationVersion" options
1706 to go along with "implementationName". These allow the user code to
1707 specify identification strings to be sent to servers.
1708 Add OID for the new ExtLite attribute set.
1710 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1711 as requested/supplid by Ere Maijala <ere@atp.fi>
1713 For generic frontend server, reverse the order of
1714 "toolkit-supplied / application-supplied" strings sent as implementationId,
1715 Name and Version. Also, remove the spaces around the slash. This brings
1716 the GFS in line with the behaviour of ZOOM-C on the client side.
1718 Add function ZOOM_scanset_display_term.
1720 yaz-client shows scan displayTerm if present.
1722 Utility yaz-iconv is now installed by default along with the man page
1725 Extend configure check for OpenSSL to use pkg-config where available (such
1728 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1729 server to specify uid/gid/mask for socket using the format
1730 unix:[user=uid,][group=gid,][umask=mask,]file=path
1731 If file= is omitted the existing format is assumed, e.g.
1733 in which case the mask is 0666 (rw for everybody).
1735 Major restructure of YAZ source. All source in libyaz is in src directory.
1736 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1737 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1739 Added man page for utility yaz-marcdump (used to be called marcdump).
1740 yaz-marcdump is installed by 'make install'.
1742 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1743 of incoming package failed.
1745 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1747 Change prototype of odr_perror: add const to message string.
1749 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1751 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1752 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1753 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1754 DNS lookup. There should not be any compatibility problems with this
1755 assuming that blocking=1 or 0 is used.
1757 Fix bad reference in UNIX comstack in function cs_addrstr.
1759 Fix for compilation on AIX.
1761 The generic front-end server (server/seshigh.c) now supports returning
1762 Init diagnostics to the client in User-information-field, in
1763 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1766 --- 2.0.4 2003/09/04
1768 Allow any CQL relation (not just all,any,exact,scr).
1770 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1771 that features the same UI.
1773 Implemented command update0 in YAZ client which is equivalent to
1774 update but uses old of Ext Update ASN.1.
1776 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1777 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1778 Previously no OID was used for this info.
1780 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1781 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1782 returns 'malformed search term' otherwise.
1784 SortResponse member resultCount now set to NULL in sort handler of
1787 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1790 Add three new utility functions for translating OIDs between various
1791 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1792 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1793 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1794 char *oid_to_dotstring(const int *oid, char *oidbuf);
1795 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1797 Reverted modifications for ES Update definition for z_IU0Update
1798 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1799 is back to YAZ 2.0.2.
1801 String value attributes for CCL parser.
1803 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1804 which their FirstSearch server returns in Init responses, sometimes
1805 carrying useful diagnostic information when Init fails. This has the
1806 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1807 "z39.50/oclcui.asn", where its definition is somewhat different from
1808 what OCLC document on their web-site, as required to interoperate with
1811 Support for anonymous authentication in yaz-client. Use the command
1814 * Fix the OID of the Index Data-local "admin" Extended Service from
1815 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1816 the 1000, which indicates a locally-defined OID, was a mistake.
1818 --- 2.0.3 2003/06/20
1820 Fix CCL directive @case handling so that it affects string match for
1821 both CCL keywords and qualifiers.
1823 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1824 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1825 Decoder has been updated with ASN.1 changes as listed in
1826 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1827 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1828 z_IUUpdate, remains unchanged.
1830 ZOOM_record_get may now return a record in a specific character set.
1831 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1832 "from" is the character set of record as returned by target. "to" is
1833 the character set to be returned. If omitted, "to" is UTF-8.
1835 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1837 New ODR utility, odr_getelement, which returns name of element for
1838 which encoding/decoding failed.
1840 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1841 in cases where a required element was omitted.
1843 Bug fix: some MARC8 sequences were not converted.
1845 New ZOOM option "step" which specifies number of records to be
1846 retrieved in one chunk. Used in conjunction with "start" and "count".
1848 SRW support for yaz-client. Use scheme http: to use it, e.g.
1851 yaz-client no longer does (un)intelligent character set conversions
1852 by default. Can be enabled with charset and marc_charset commands.
1854 xmalloc trace fix for 64-bit systems such as DEC alpha.
1856 Solaris 2.6 compile fix.
1858 New function, cql_strerror() translates SRW error codes, as returned
1859 by cql_transform_error(), into human-readable English strings. Used
1860 in yaz-client diagnostics when appropriate.
1862 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1863 converts it into a type-1 query which is sent to the server. This
1864 makes CQL available for use with all Z-servers, as opposed to the tiny
1865 minority that can handle CQL queries themselves.
1867 --- 2.0.2 2003/04/28
1869 New Debian package layout similar to the Redhat Package layout.
1871 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1872 and search result respectively.
1874 --- 2.0.1 2003/04/25
1876 Redhat package is now several packages: libyaz (runtime libraries),
1877 libyaz-devel (development and documentation, and yaz (utility programs).
1878 Package spec file by Morten Bogeskov.
1880 New member 'schema' in struct bend_fetch_rr which the name of requested
1881 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1882 handler MAY set this to reflect the schema of the returned record.
1884 New member 'display_term' in struct scan_entry. GFS now sets member entries
1885 and allocates scan entries to be filled by user scan handler. In previous
1886 version, entries member was allocated by the scan handler. That still works,
1887 but the GFS will ignore member display_term - assuming it was NOT set by
1888 the handler. The fact that the GFS now allocates the entries both allows
1889 for new members and makes a scan handler easier to write.
1891 Fix CQL lex buffer overflow.
1893 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1894 SRU default recordPacking is string.
1896 SRU protocol support for frontend server.
1898 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1900 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1902 Added scan for the ZOOM shell (zoomsh).
1906 * String Identifers for Schemas (Amendment 5).
1907 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1908 Old definition for schema
1909 Odr_oid *schema; /* OPT */
1914 Z_InternationalString *uri;
1915 #define Z_Schema_oid 1
1916 #define Z_Schema_uri 2
1919 * resultCount parameter to Sort Response (Amendment 1).
1920 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1922 Support for SRW 1.0 over HTTP. This is an optional feature and
1923 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1926 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1927 on the same port. SRW SearchRetrieveRequests are mapped
1928 to bend_init,bend_search,bend_fetch,bend_close.
1930 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1932 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1933 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1935 ZOOM connections are SRW based if schem http is used for hostname
1936 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1937 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1939 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1940 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1941 distance=n, order=true/false, relation=le, prox unit=word. If
1942 n is omitted, distance 1 is used.
1944 Fixed problem with C compiler include path in wrong order.
1946 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1947 on Solaris. Patch from Ko van der Sloot.
1949 New MARC decode API. All new functions operate on a yaz_marc_t
1950 handle. The most important new functions are: yaz_marc_create,
1951 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1952 decode and destroy respectively. Decoder can produce formats
1953 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1954 include/yaz/marcdisp.h.
1956 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1957 to UTF-8, UCS-32, wchar_t or Latin-1.
1959 * Prototypes for yaz_iconv_-functions moved to separate header
1960 include/yaz/yaz-iconv.h.
1962 Make a few private functions 'static' in unix.c. This prevents
1963 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1965 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1966 are set when Init Response is received.
1968 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1969 but returns diagnostic set as well.
1971 New function yaz_strerror which is a portable wrapper for
1972 strerror/strerror_r/GetLastMessage.
1974 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1975 is returned for MARC. If type is "oai", then OAI MARC is returned.
1977 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1980 --- 1.9.2 2002/11/26
1982 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1984 Fix bad race conditions on SIGTERM and terminate gracefully in
1987 Move retrieval (data1) module to Zebra since nobody seems to be
1990 Add GRS-1 render for ZOOM using same format as yaz-client.
1992 --- 1.9.1 2002/10/05
1994 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1996 Fix broken ESpec handling in data1 module.
1998 SGML reader parses comments and makes them part of the data1 tree.
2000 Added several type casts so that YAZ compiles as C++ code.
2002 ZOOM didn't handle PDU encoding failures properly.
2004 Added more Bib-1 diagnostics (approved extensions).
2006 GNU configure: better check for iconv.
2008 More portable use of accept, getpeername. Check for socklen_t. Use
2009 int/size_t if socklen_t is not defined.
2013 PQF parser rejects bad queries - including those with extra
2014 characters in them. PQF parser used to silently ignore that.
2015 Cleaner API for PQF added, which allows you to get detailed
2016 error information for bad queries (see yaz/pquery.h).
2018 Fixed bug in ZOOM_record_get for type "database".
2020 Implemented mini iconv library supporting conversions between
2021 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2023 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2025 --- 1.8.9 2002/08/20
2027 Fixed ZOOM C record cache so that preferredRecordSyntax and
2028 elementSetName is used to check for already fetched records.
2030 --- 1.8.8 2002/08/02
2032 Added three members in bend_initrequest structure to facilitate
2033 character set negotiation.
2035 Fixed a bug in frontend server that could cause indefinite
2036 loops under rare conditions.
2038 Revised character set utilities (charneg.h) so that encoding
2039 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2041 For PQF, directive @term <type> sets term type for Scan/Search.
2042 Here <type> is general, string, numeric, null. The term type
2043 is inherited - just like @attr.
2045 New call odr_set_charset that sets character set conversion for
2046 international-strings on a ODR stream. Prototype is:
2047 int odr_set_charset(ODR o, const char *to, const char *from);
2048 The InternationalString is still represented as C string in YAZ
2049 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2050 won't). On the protocol level, you can use any encoding.
2052 Support for UNIX sockets in ZOOM.
2054 Solaris recv sometimes returns errno == ENOENT. It is treated as
2055 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2057 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2058 both client and server. Code by Morten Bogeskov.
2060 --- 1.8.7 2002/05/22
2062 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2063 that they can be used directly from Visual Basic. You must recompile
2064 your windows APP if you're using ZOOM.
2066 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2067 Commands "lang" and "charset" sets language and character set respectively.
2068 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2069 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2071 Attributes from multiple CCL fields may be OR'ed rather than merged
2072 using directive "@field or". Fields are still merged by default -
2073 equivalent to "@field merge".
2075 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2078 Fixed bug in zget for parameter ExtendedServicesResponse.
2082 --- 1.8.6 2002/03/25
2084 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2086 Client displays USR.1:SearchResult-1 (hits per term).
2088 Additional Search Info for search in Generic Frontend Server.
2090 Fixed CCL parsing of "field=s".
2092 WIN32 installer - using the excellent NSIS software from nullsoft.
2094 Fixed CCL parsing of "field = - <number>".
2096 Added function yaz_marc_decode that decodes MARC for line mode
2097 display or XML (similar to that used by JZKit).
2099 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2100 Z39.50. But ISO/ILL was, however.
2102 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2103 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2105 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2106 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2108 --- 1.8.5 2002/02/03
2110 New YAZ client features: Command completion and new commands:
2111 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2112 Code provided by Jacob Poulsen.
2114 New call oid_trav, that visits all registered OIDs via callback.
2116 Function ZOOM_record_get now returns const char pointer rather than
2117 void pointer. It saves a lot of type casts.
2119 For YAZ client, command "auth" now allows you to set authentication
2120 in IdPass style. It is enabled when three tokens are given - order
2121 is user, group and password.
2123 Fix memory leaks in MARC record handling for ZOOM.
2125 New option for YAZ client, -k <kilobytes> that sets
2126 maximum record size. Similar to -k option for generic frontend
2127 server and yaz-ztest.
2129 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2131 Prefix query parser reports "fail" when bad attribute set is given.
2133 Fix in MARC decoder. Proximity logging. Fix for attribute set
2134 in scan handler for server. Patches by Shigeru Ishida.
2136 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2139 Configure option --with-openssl=<dir> now works when a directory is
2140 specified. Patch provided by Morten Bogeskov.
2142 New option for YAZ client, -u <auth>, that sets authentication.
2144 ZOOM fix: error information was sometimes "missing", since error
2145 was cleared/reset too when it shouldn't.
2147 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2149 --- 1.8.4 2002/01/04
2151 Scan for ZOOM API. New object ZOOM_scanset. New functions
2152 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2153 ZOOM_scanset_destroy.
2155 New ZOOM function, ZOOM_connection_last_event, that returns type
2156 of last event (such as "receive data", "send data", "apdu received",
2159 New ZOOM option, schema, that specifies schema for retrieval.
2161 New CCL feature. Qualifiers can be aliases for one or more
2162 other qualifiers (if more than one is given, OR is used).
2164 ZOOM uses named result sets if target supports it.
2166 Two new YAZ client commands: . (dot, which sources a script of YAZ
2167 client commands), and ! (to execute shell command.). Implemented
2170 Working on Debian packages.
2172 --- 1.8.3 2001/11/19
2174 YAZ client enables named result sets only if target supports it.
2176 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2178 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2179 with key="host" to get same result.
2181 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2182 Function Z3950_resultset_record(s) returns references to records
2183 "owned" by resultset. To become owner use Z3950_record_clone.
2185 Function z_ext_record handles Extended Services. Thanks to
2188 --- 1.8.2 2001/11/12
2190 CCL Parser fix: ignore token comma when dealing with and-lists.
2192 Documentation updates for COMSTACK.
2194 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2195 Changed prototype Z3950_records. For some functions, int parameters
2196 were changed to size_t.
2198 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2201 New MARC decode/display function, marc_display_exl, which properly rejects
2202 non-ISO2709 records. YAZ client uses it.
2204 --- 1.8.1 2001/10/29
2206 Fix bug: local attribute set wasn't set correctly in PQF strings.
2210 * Old Z39.50 codecs no longer supported.
2212 Added ZOOM C binding. See http://zoom.z3950.org/
2214 Renamed states for COMSTACKs to avoid confusion with events.
2216 Implemented cs_look and proper cs_rcvconnect.
2218 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2220 Configure detects POSIX threads on OpenBSD.
2222 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2223 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2225 When error is returned from present handler, non-surrogate diagnostic
2226 is returned in present response (and fetch handler is no longer called).
2228 * Minor adjustments to pquery parser (PQF). Token characters may be
2229 escaped by using backslash (C-style).
2231 PQF parser allows string attribute values to be specified. For @attr,
2232 non-numeric characters after the equal-sign are treated as strings
2233 (e.g. @attr 9=title).
2235 CCL trunction character may be defined (@truncation in file)
2237 * function zget_ExtendedServicesRequest sets waitAction to
2238 waitIfPossible (was wait).
2240 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2243 CCL operator names may be set in field definition files (CCL_bibset).
2244 See ccl/bib1 for an example.
2246 Fixes in ASN.1 compiler for C++ compatibility.
2248 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2249 and "op_or" to avoid conflict with C++.
2251 Fixed problem with GNU readline detection on Redhat 7.0.
2253 Added step-size for Scan backend handler.
2255 Fixed bug that made the frontend server crash when no attribute
2256 set was specified for scan.
2258 Front-end server automatically switches to original working directory
2259 when installed as an NT service. Previously -w had to be specified to
2262 Added extended attributes for retrieval module (data1), so that data1
2263 records carry d1_readXML/SGML attributes. d1_read also supports
2264 null-data rules ( <tag/>)
2266 On UNIX when POSIX threads are available, a separate library libyazthread
2267 is created. Programmers should link with that library and the yaz library
2268 when using threads. The reason for the split was that some applications
2269 on Linux, such as Apache, doesn't work well when using shared objects that
2272 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2273 (or any frontend server) in SSL mode by specifying ssl: followed by
2274 address. Only tested on UNIX.
2276 Added feature for CCL module. Virtual structure s=al or s=ol generates
2277 and-list and or-list respectively instead of phrase search.
2281 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2282 log_mask_str. This was done to avoid name conflicts with other libraries
2283 (such as other PHP extensions).
2285 Added raw OID member for preferred record syntax (request_format_raw)
2286 and returned record syntax (output_format_raw) for backend fetch method.
2288 Config file yaz-config now accepts options so that it returns specific
2289 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2291 Shared library support for UNIX using GNU libtool.
2293 * Modified backend interface. Request/Response struct's replaced by
2294 one read/write C struct. For example bend_fetchrequest and
2295 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2296 Every handler - even search has to be registered in bend_init
2297 handler. This means that the YAZ library no longer refers to
2298 external functions and it makes it possible to make the whole
2299 thing a single DLL/SO.
2301 Added Segment handler for backend server.
2303 Added Zmbol/Zebra administrative functions to YAZ client.
2305 Threaded frontend server on UNIX (when POSIX Threads are available).
2306 Starting the server with option -T enables multi-threading.
2310 Added configure option --enable-comp/disable-comp to control use
2311 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2312 located in sub directory asn.
2314 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2315 in ${exec_prefix}/bin along with the other programs yaz-client and
2318 GNU automake used to maintain makefiles.
2320 Added several OID's.
2322 Changed retrieval module so that we can load records with no abstract
2323 syntax defined. Tagpaths in these records are fully composed of string
2326 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2330 On UNIX, the generated makefile now supports a proper 'make install'.
2331 The prefix can be set via GNU configure to set the install location
2332 (default is /usr/local).
2334 * YAZ programs client and ztest were renamed to yaz-client and
2335 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2336 locations, such as /usr/bin,/usr/local/bin,etc.
2338 * YAZ Header files were moved from include to include/yaz. YAZ Header
2339 files are referred to as include <yaz/log.h> rather than <log.h>.
2340 The YAZ include path (-I ..) is therefore the same as before. Programmers
2341 should update their #include statements or use -Ipath/include/yaz
2342 instead. The main motivation for doing this change is that YAZ header files
2343 can be installed in "standard" locations /usr/include,/usr/local/include
2344 without introducing conflicts, since ALL YAZ header files are stored
2345 in subdirectory yaz (under /usr/include for example).
2347 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2348 rather than project/workspace files. We switched because project files
2349 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2352 Changed name of logging function, logf, to yaz_log, to prevent name
2353 clash with some math-log functions. The YAZ header log.h defines logf
2354 to yaz_log (#define) so there should be no incompatibilities by this
2357 Added bend_start/bend_stop handlers for server. These handler are
2358 called on start/stop of server. For windows they are called whenever
2359 a service is started/stopped.
2361 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2362 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2363 in util/yc.tcl. The auto-generated C code structures are, in a few
2364 cases, incompatible with the old decoders. There are differences in the
2365 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2366 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2367 The preprocessor variable ASN_COMPILED is defined when the compiled
2368 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2369 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2370 wish to use the old encoders/decoders you can specify --disable-yc
2373 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2374 version so that it supports both new - and old version of DB Update
2376 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2377 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2378 change. The name parameter can be set to 0 in which no name is specified
2379 for the construction. The macros odr_implicit and odr_explicit sets name
2380 parameter to zero for the construction involved. New macros
2381 odr_implicit_tag and odr_explicit_tag are similar to the others,
2382 except that a name parameter is added. For programmers' that don't use
2383 ODR they probably only need to change the call to z_APDU and z_External.
2385 Added access control facility by interfacing the TCP wrapper library.
2386 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2387 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2388 name of the daemon and enables the access control as specified in
2389 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2391 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2392 den Dool <H.M.vdnDool@kub.nl>.
2394 Added reference ID parameter to most functions in server API - refer
2395 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2397 Changed name of ccl library to libccl.a (was ccl.a).
2399 Fixed bug in decoder for Explain (Category TargetInfo).
2401 Added support for GNU readline in client. Thanks to Jacob Poulsen
2402 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2404 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2405 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2406 IMPLEMENTATION! This change was made to the development version before
2407 the ZIG decided to retract the amendment. If any users MUST be
2408 compatible with the original Update definition, PLEASE CONTACT US, and
2409 we will include a separate definition corresponding to the old Update
2410 ES. Note that because of the change to the ASN.1 of the
2411 TaskPackageRecordStructure we cannot define a single structure that
2412 will support both versions.
2414 * Added const modifier to buffer parameter for some ODR/BER encoding
2415 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2416 completeWAIS, odr_dumpBER.
2418 Fixed bug in client.c which caused a crash when a scanResponse didn't
2419 contain positionOfTerm.
2421 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2422 * will cause an error in a client if a non-YAZ target sends both a
2423 * list of Scan entries and non-surrogate diagnostics.
2425 Retrieval module enhancements. Tag sets may be typed in the reference
2426 to it. From the .abs-file the "tagset" directive takes a third optional
2427 integer type for the tag set referenced. From a .tag-file the "include"
2428 directive takes a third optional type as well. The old "type" directive
2429 in the tag set itself is still recognized but acts as the default type
2432 Backend interface change. Individual Scan terms returned from bend_scan
2433 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2434 in include/backend.h.
2436 Retrieval module enhancements. Multiple tag sets and attribute sets may
2437 be specified in abstract syntax specs. Revised the error/warning for
2438 logging messages reported by the retrieval module when reading the
2441 Object Identifier system (oid_..) changed. The API is backwards
2442 compatible but the oid-routines now allocates new OID's when needed.
2443 Raw OID's may be specified in oid_getvalbyname.
2445 YAZ now uses GNU configure to generate Makefile(s).
2447 * Minor changes in some of the member names of DeleteResultSetRequest and
2448 DeleteResultSetResponse. See include/proto.h.
2450 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2451 and added member 'languages' in TargetInfo (which was missing).
2453 Changed the way attribute sets are handled in the retrieval
2454 module. These are now cached, just like the abstract syntaxes
2457 Changed YAZ so that it links with compiled ASN.1.
2459 Added Explain-schema definitions and mapping routines. The following
2460 Explain categories have been implemented: AttributeDetails,
2461 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2463 Fixed minor bug in Windows version of Server Library.
2465 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2467 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2469 Added EXTERNAL: UNIverse Resource Report (non-standard).
2471 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2472 ENUMERATED and SET OF.
2474 * Added 'const' to some of the char pointer arguments for the
2475 functions, data1_read_node, data1_getelementbytagname,
2476 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2479 Fixed bug in data1_insert_taggeddata - the last_child member of
2480 parent wasn't initialised.
2482 * Changed data1_read_record and data1_read_node so that the supplied
2483 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2484 doesn't refer to any parts of the "SGML"-buffer.
2486 Fixed bug in server library (Windows version of statserv_remove).
2488 * Changed code so that it compiles as C++. The type definition
2489 of Odr_fun which is a member of Odr_arm was changed. The result is,
2490 that an explicit typecast is needed for the fun pointer when
2491 using Odr_arm - as in:
2492 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2494 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2496 Implemented the new structured date and time definition as approved
2497 by the ZIG. Added schemaId element to the specificTag in Espec-1
2498 (also approved at the last ZIG). Thanks to RVDM.
2500 Added some Object identifiers (RVDM).
2502 Changed the Update Extended Service (RVDM).
2504 Added command "refid" to client which specifies referenceId for
2505 the following requests.
2507 Implemented extended service handling for server. See ztest.c
2508 for an example as well as backend.h. New handlers are registerd
2509 in the Init handler.
2511 * Changed interface for sort in server.
2513 Added new members to statserv_options_block. It allows a server
2514 to read options from another source than just the command line. Thanks
2515 to Charles Woodfield.
2517 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2518 renamed to zboolean. Some C++ compilers complained about the name.
2520 Minor changes to gils.abs. Added index 's' (sort) on title
2521 and date/time-last-modified.
2523 --- 1.4pl2 1998/1/30
2525 Fixed bug in server library regarding inetd mode (-i). This bug
2526 was introduced by release 1.4.
2528 --- 1.4pl1 1998/1/29
2530 Added sort facility in client and backend server interface.
2532 Fixed problem with dependencies in Makefile(s).
2534 Fixed bugs for encoders/decoders of extended services and
2537 Implemented sub-tree feature for schemas. Sub-trees are
2538 referenced in *.abs-files. See explain.abs for an example
2539 of the use of this feature.
2541 Modified bib1.att; local attributes for ANY didn't include
2542 ANY itself (only affects use of the retrieval module).
2544 Fixed bug in plain SGML reader in function data1_read_node:
2545 tags with prefix "var" was incorrectly interpreted as variants.
2547 Added feature "sub-schemas" to enable references to - and definitions
2548 of - group of elements.
2550 * Removed member parent from type data1_element (in data1.h).
2552 Implemented function odr_nullval() that returns the value of
2555 * Removed member num_children from data1_node (in data1.h).
2557 Made NT service interface part of the server library. The
2558 function statserv_main uses the NT service when required and
2559 calls the statserv_start / statserv_close routines.
2561 Routine zget_SearchRequest and zget_PresentRequest fills
2562 resultSetName/Id member with "default" instead of "Default".
2564 Fixed memory leak in server. Request queue member wasn't freed.
2566 Fixed nmem_exit so that memory is freed.
2570 Revised the CCL parser utility to be thread safe.
2572 Added function, oid_ent_to_oid, to replace the function
2573 oid_getoidbyent, which is not thread safe.
2575 * Added nmem_init and nmem_exit to initialize and release
2576 NMEM resources. Function nmem_init should be called once in the
2577 initial thread before NMEM/ODR is used. statserv.c and client.c
2578 have been changed accordingly. The change was necessary to make
2579 NMEM thread safe. The NMEM memory pool is shared amongst threads
2580 in a process. Unix-based applications will still work fine without
2583 Added NT Services interface for the the Z39.50 (statserv) Server.
2584 Refer to the ztest.c source on the usage.
2586 Windows 95/NT port using MSVC5.0. Project files are included in the
2589 * Defined new 'global' handle for the retrieval (data1) system. The
2590 new handled, data1_handle, describes the state of the data1 system.
2591 This handle is passed as first argument to virtually all
2592 data1 related routines. The functions data1_create and data1_destroy
2593 creates and destroys a data1 handle respectively.
2595 Added ODR encode stream member to all backend request structures
2596 init, search, scan etc. This stream should be used to allocate all
2597 memory used for the response when thread safe operation is needed.
2599 Changed the comstack utility, cs_addstr, to be thread safe. The
2600 returned hostname string returned by the function is now part the
2603 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2604 function. The cs_straddr takes a COMSTACK handle as argument, so this
2605 function must be used after cs_create and before bind/connect.
2606 This function is thread safe.
2608 Moved test server to 'ztest' directory - generic server code still
2609 in 'server' directory.
2611 Made prefix query (pquery.c) utility thread safe.
2613 Added new function modifier YAZ_EXPORT to 'export' public DLL
2614 functions when using windows (see include/yconfig.h).
2616 Added definitions to the OID database (util/oid.c) (RVDM).
2618 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2620 Added call to ccl_rpn_delete in client program.
2622 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2623 release of RPN structure.
2625 Added support for C++, headers uses extern "C" for public definitions.
2626 With input from RVDM.
2628 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2629 Thanks to Ronald van der Meer (RVDM).
2631 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2633 Added support for private extensions to the OID database
2634 (oid_setprivateoids()). Thanks to RVDM.
2636 Added optional, physical ANY (key replication)
2638 Fixed null-reference problem in GRS-1 output filter.
2640 Proximity operator added to Prefix Query Format (PQF).
2642 In test client command "base" accepts multiple databases.
2644 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2648 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2650 Smallish bug-fixes in the new encoders/decoders (explain).
2652 Bug fixed in DeleteRequest.
2654 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2656 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2658 Added SOIF syntax (using private OID for now) to retrieval module and client.
2660 Added Update extended service.
2662 Added SearchResult-1 additional info structure.
2664 Added optional CCL (ISO8777) interpreter as separate module. Available
2667 --- 1.2 1996/6/10 (1st anniversary release)
2669 Added Summary record syntax. Lightly tested.
2671 Added OPAC record syntax. Untested.
2673 Added ResourceReport service encoders/decoders. Untested.
2675 Fixed bug in z_Unit - wrong tagging on unitSystem.
2677 Fixed bug in the DiagRecs decoder.
2679 Added options for max PDU size and session timeout to frontend-server.
2681 Added documentation of query-language parsers and other supporting utilities.
2683 [frontend-server] Added Attribute set to the bend_scanrequest API.
2685 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2686 surrogate diagnostics were generated.
2688 [retrieval] Allow multiple local values for attribute.
2690 [retrieval] Allow multiple attributes per element in .abs files. index type.
2692 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2694 --- 1.1pl2 1996/4/10
2696 Minor changes, mostly specific to Zebra's requirements (retrieval)
2700 Repaired bug in frontend server when running multiple listening
2701 endpoints in dynamic mode.
2703 z_External() now won't break if a known, ASN.1 value comes encapsulated
2704 in an octet-string. The value will pass through unmodified in an Odr_oct.
2706 Added a bit of code to the demo client to decode & display
2707 ASN.1-structured records represented in the octet-aligned branch of
2708 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2710 Added z_ext_getentbyref() to the ASN module. Doc updated.
2712 * Completed the SCAN definition in the ASN module. This may break SCAN
2713 code based on older YAZ-versions at compile-time. The fix is easy -
2716 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2717 under the SCAN definition. Remember to initialize this, server-people.
2719 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2720 that this does not extend to ODR and ASN.
2722 Comstack allows insertion of established socket (primarily for
2723 inetd-operation of servers). Doc updated.
2725 Front-end server can now start from the inetd in TCP mode. Doc
2728 --- 1.0pl4 1996/1/24
2732 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2733 the rank and record number.
2735 Adjustments to the frontend server.
2737 Fixed diagnostic BER dumper. It ignored the file argument.
2741 Various changes to retrieval module.
2743 Changed the union discriminators of the protocol files from enums to
2744 ints paired with #defines.
2746 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2749 *Changed operator in the RPN structure to 'roperator', again to avoid a
2752 Fixed problems in Explain decoders/encoders.
2754 --- 1.0pl2 1995/12/6
2756 Memory bug in log module fixed.
2758 --- 1.0pl1 1995/12/5
2760 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2762 Bug in Explain DatabaseInfo module fixed.
2764 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2768 The shift to v1.0 signals that we now consider the *core* functionality
2769 of YAZ reasonably stable (the core being more or less equivalent to
2770 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2771 tested (Explain not at all - though that will happen soonish).
2773 Minor changes to code to support Windows port.
2775 Various minor changes after we're getting to use GRS-1 & co. more.
2777 Added Espec-1 format.
2779 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2780 of the protocol and it cannot be selected when encoding (maps into 'string'
2781 when decoding). Needed to talk to some servers.
2783 Demo client can request simple element set names.
2785 Added Diagnostic Format encoders/decoders.
2787 Added simple Close handling to frontend server (no hooks for resource
2788 reporting yet), and demonstration client.
2790 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2792 --- 1.0b3 1995/08/24
2794 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2795 handled incorrectly when records were requested in the searchResponse. This
2796 will only affect you if you use the frontend-server.
2798 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2799 Test-client will ask for and print GRS1. Ztest will return dummy records
2802 Added Explain encoders/decoders to the service-level API. Untested.
2804 Added Extended Services: Item Order encoders and decoders to the Service-
2805 level API. Untested. We could use a recent copy of the pertinent bits
2806 of the ILL protocol to add those bits.
2808 Added diagnostic format 1 encoders/decoders to the service-level API.
2811 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2812 odr_cons.c, which causes a more correct output.
2814 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2815 was always set to 0 when no records were requested in the searchRequest.
2817 * Added better external-handling. This shouldn't harm old code that
2818 *encodes* externals. It can break code that looks for a
2819 'single-ASN1-type' representation, since those types that are known
2820 are now decoded immediately. Look at the SUTRS sample code in
2821 seshigh.c and client.c. Documentation updated.
2823 Handling of structured records in bend_fetchresponse. Length -1 marks
2824 structured record, type is deduced from format field.
2826 --- 1.0b2 1995/06/27
2827 Fairly quick maintenance release to add SUTRS support.
2829 Fixed handling of SUTRS records in the demonstration client.
2831 * Added format field to the bend_fetchrequest and bend_fetchresponce
2832 structures of the backend API (frontend server). When the record is
2833 returned, the value of the format field is mapped to an OID. The
2834 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2835 of the record. The special value VAL_NONE in the bend_request means
2836 that no specific format was requested by the client. Documentation
2837 updated accordingly. Test server (ztest) will return a fixed dummy
2838 SUTRS record if your client requests SUTRS.
2840 Documentation updated accordingly.
2842 You can now set external libraries and RANLIB support in the top-level
2846 First public release.
