3 New utility for managing threads - thread_create.h.
5 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
6 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
7 but YAZ' implementation do.
9 Fixes for yaz_cond-functions on Windows 7.
11 DLL export more symbols.
13 zoomsh: show record do NOT render opac.
15 Remove *.la files from Debian and RPM packages.
19 Debian package libyaz-dev depends on libgnutls-dev again (was
20 removed in YAZ 4.0.6, but due to Libtool it is still needed
21 even though yaz-config do not list libgnutls libs).
23 ZOOM: Use only one WRBUF for returning string results for
24 ZOOM_resultset. Reduces memory usage for ZOOM in general.
26 ZOOM: ZOOM_connection do not use a shared pointer to
27 ZOOM_resultset after ZOOM_resultset is destructed by
28 user. Reverts to YAZ 4.0.4 behavior.
32 record-conv: fix problem with at least one XSL conversion -
33 due to probably incorrect usage of XML XSL documents.
37 Fix yaz-config for static mode and the use of SSL (gnutls).
41 Forward decl timeval struct in mutex.h and gettimeofday.h.
43 yaz-config: fix 'static' mode linking.
47 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
48 are wrappers for pthreads or Windows. For Windows these are put in
49 a separate DLL: yaz_cond4.
51 libyaz.la (whole source) is compiled with thread. If thread support
52 is enabled enabled, all source of YAZ is compiled with treading support.
53 This allows core utilities such as yaz_log to use thread facilities.
54 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
55 thread utilities. This commit moves mutex utilities (mutex.c) from
56 libyaz_server.la to libyaz.la.
58 yaz-json-parse displays leading text until error.
62 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
63 patch from Giannis Kosmas.
65 SRU: no longer URL encode SRU database. The URL for an SRU server is
66 a URL and such is alreeady encoded - at least when given with leading
67 http:// or https://. This reverts behavior to YAZ 3.0.50.
69 Support for new MARC XML notation TurboMARC which like MARCXML is a
70 complete representation of MARC/ISO2709.. This one, however, is more
71 compact and allows for faster processing with XSLT. TurboMARC can be
72 used in the marcdisp.h API, from the yaz-marcdump utility and from
75 yaz-ztest can be configured - via the database - to perform certain
76 delays when it performs operations search, present and single record
77 fetch. This allows testers to make yaz-ztest act as a real or even slow
78 Z39.50 server. Refer to the yaz-ztest man pages for details.
82 wrbuf_destroy allows NULL WRBUF passed to it.
84 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
86 Add ZOOM_connection_close.
88 No fixed size buffers for ZOOM shell - bug #3257.
90 tstodr: make it work on s390 platform.
92 New icu iterator-functions. The new icu_iter-functions makes it possible
93 to use ICU chains from many threads.
95 yaz-client: better syntax check for show command.
99 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
102 New simple local-file XML include facility which allows file glob-patterns.
103 Refer to yaz/xml_include.h.
105 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
108 ZOOM_record_get supports new parameter "format" which makes it format XML
111 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
112 JSONText in ECMA-262) is JSONValue, not JSONObject.
116 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
117 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
119 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
120 POSIX/Unix builds .so with major version 4.
122 Remove old LOG_-defines from log.h. They have been obsolete and
123 undefined by default for the last 5 years.
125 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
127 GFS: Remove socket (int *fd) from search_rr handler. The socket
128 descriptor ptr is a facility that allowed a search handler to supply
129 a socket which would serve as a callback - when search was complete.
130 This facility has now been in use for years.
132 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
133 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
134 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
135 returns 'const char *' rather than 'char *. The returned string is
136 read-only and should not be modified by applications. COMSTACK cs_close is
137 now a void function - it no longer returns int. No applications check for
138 the value and the implementations has always returned 0.
140 ZOOM: use size_t for scan hit counts and str size. Functions
141 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
142 occ (hit count) and len (string length) are now of type size_t pointer
143 rather than int pointer. This is to be able to represent large hit counts
144 and to also just to use the proper type for string length (strlen result).
146 New JSON parser. Refer to include/yaz/json.h .
148 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
149 Used to be int in some cases. Many wrbuf_-functions used to return an int
150 indicating some length.. These return values were never used. And so they
153 ODR: odr_malloc, odr_total now takes size_t for size.
155 clone_z_type: fix leak; occurred for encoding failures.
157 --- 3.0.52 2009/12/03
159 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
160 bug was introduced in 3.0.51.
162 --- 3.0.51 2009/12/02
164 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
166 tcpip comstack: fix leak for getaddrinfo.
168 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
169 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
170 Decoding of SRU "path" database is performed by private function
171 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
172 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
174 yaz-client: honor base command for SRU. Change when database setting
175 is applied for SRU and ensure it is kept when a connection is reset.
176 Change also the way errors are displayed or SRU (decoding of packages).
178 --- 3.0.50 2009/11/02
180 Add support for extra request / response data for SRU codecs and GFS.
181 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
182 for extra data response buffer and length. For the GFS, both request
183 and response data (XML) is carried in extra_args and extra_response_data
184 for the search handler. Patch by Ko van der Sloot.
186 ZOOM: For queries that cannot be converted to the specified rpnCharset,
187 ZOOM now returns a diagnostic on the client-side ('invalid query' /
188 10010). This fixes bug #2113.
190 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
191 cmdfile included a 'quit' command that would result in a memory violation.
193 --- 3.0.49 2009/10/01
195 Make a number of functions defined in xmlquery.c static. These have
196 never been declared in a public header file (yaz/xmlquery.h) and was
197 made public by mistake.
199 Improve speed of character conversions (iconv utilities). This makes
200 conversions from MARC-8 faster.
202 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
203 unless type desired is "raw". This will prevent type "xml" from
204 returning ISO2709 .. Which obviously can not be XML parsed.
206 Fix memory leak in ZOOM that would occur if option apdulog was used
207 on a re-used connection.
209 Frontend server logs HTTP requests.
211 Frontend server now sends Z39.50 close when it times out (sesssion has
212 been idle for too long). Versions 2.0.30 and earlier also sent close.
213 But due to a mistake this was disabled in all versions after that, i.e.
214 the server would just close the socket immediately.
216 yaz-client emits a better message when receiving an unrecognised
217 userInformationField.
219 Skip zero-length subfields when decoding ISO2709. This rare case happens
220 if a record has two FS characters in a sequence. Without this patch
221 there would be a reference beyond char array in using_code_len fragments
224 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
226 --- 3.0.48 2009/08/28
228 The show command offered by the zoomsh command now takes a 3d optional
229 parameter type which is what is passed to ZOOM_record. If the type
230 argument is omitted, "render" is used.
232 RPN to CQL conv may use USE string attributes (bug #2978).
234 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
236 --- 3.0.47 2009/07/08
238 Function yaz_xml2query allows a diagnostic element in the PQF XML
239 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
240 code and additional info respectively.
242 The BER BOOLEAN is now the integral type Odr_bool which still happens
243 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
244 typedef'd to Odr_int. This is still an integral 'int', but it may be
245 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
246 ASN-1 compiler as well as programs has been updated to use the new types.
248 --- 3.0.46 2009/06/08
250 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
251 only the bibliographic record was rendered. For type=opac, an OPAC
252 record is only returned if it is present.
254 iconv: small fix for encoding of advancegreek.
256 yaz-client: avoid double display of SRU/SRW records (bug #2798).
258 yaz-client: option auto_reconnect=on really reconnects.
260 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
262 server: avoid null ptr ref for for yaz_poll errors.
264 build: fix RPM build for RHEL 5.3.
266 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
268 --- 3.0.45 2009/03/31
270 Fixed bug #2709: TCP connect returns Invalid argument.
272 Fixed compilation for mingw.
274 Honor charset for raw records (ZOOM_record_get).
276 Fixed use of errno for threaded mode that was seen on Solaris 10.
278 Fixed argument passing with blanks in value for Windows Service.
280 Disable YAZ' own log rotate by default (no 1 GB limit).
281 The variable l_max_size which specifies the log file limit is set to 0
282 (DISABLED): This is due to the fact that YAZ is most often deployed using
283 logrotate. Also YAZ can not perform log rotate because of unsufficient
284 permissions (setuid).
286 --- 3.0.44 2009/02/17
288 List supported encodings in man page for yaz-iconv.
290 Fixed missing SSL libs for --libs output
292 Re-established OID record syntax application-xml. Nobody should use it
293 but we don't want to change soname because of this symbol being absent.
295 --- 3.0.42 2009/02/02
297 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
299 Added member named_result_sets for init handler struct for the GFS. This
300 allows a server to disable named result sets.
302 Removed OID record syntax application-xml.
304 Added support for rule-based transliterator for ICU wrapper of YAZ.
306 Fixed bug #1902: yaz-icu XML output.
308 Make YAZ checks Emacs friendly.
310 BITSTRING value shows value. Bug #2346.
312 ISO2709 decoding: skip control characters from indicator data.
314 Omit sort key by default in yaz-icu's output.
316 Allow combined single char options (again) for YAZ' options function.
318 Utility yaz-marcdump got option to display YAZ version (-V).
320 Allow YAZ to use ICU 3.4.
322 Added new ICU test case which illustrates removal of diacritics.
324 --- 3.0.41 2008/12/29
326 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
328 --- 3.0.40 2008/12/29
330 For configure, using option --without-xml2 also disables Libxslt/Libexslt
333 Fixed bug #2352: yaz-marcdump crashes for certain record.
335 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
337 Added support for Danmarc2 to UTF-8 conversion.
339 Added support for ISO5426 to UTF-8 conversion.
341 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
342 implementation version.
344 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
346 --- 3.0.38 2008/11/10
348 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
349 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
351 ZOOM C now interprets databaseName option for ZOOM connection as path
354 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
356 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
358 Dummy Libxml2 types no longer defined in headers of YAZ'.
360 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
363 --- 3.0.36 2008/09/26
365 Various ODR chapter fixes.
367 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
369 Added missing source for Windows compilation, mutex.c.
371 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
373 For SRU connections in ZOOM all records up to "count" are now fetched.
375 Fixed crash in generic frontend server (and yaz-ztest) which occurred
376 in Windows due to bad error handling for Libxml2.
378 Added facility for sending arbitrary records (ASN.1 any) using
379 ZOOM C's Extended service update. Patch by Sam Reynolds.
381 New options for ZOOM C's connection, logapdu which makes ZOOM log
384 --- 3.0.34 2008/06/18
386 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
388 --- 3.0.32 2008/06/12
390 Fixed memory violation that could occur when decoding UTF-8. This bug
391 was only present in 3.0.30 of YAZ.
393 --- 3.0.30 2008/06/06
395 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
396 GNU TLS is used by default (if found).
398 yaz-ztest returns OPAC records if a client asks for OPAC.
400 Improved speed of MARC-8 encoding.
402 Added support for lossy and loss-less MARC-8 encoding.
404 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
406 Added new Windows Service wrapper (sc).
408 yaz-client's itemorder command may now send a file.
410 Fixed yaz-marcdump to allow the use of NS prefix for record element.
412 Added new function yaz_log_xml_errors.
414 Allow (but warn) unknown XML attributes in MARCXML parsing.
416 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
418 The UTF-8 to MARC-8 conversion now uses a different set of characters
419 for Greek symbols. Bug #2120.
421 --- 3.0.26 2008/02/21
423 Added yaz_daemon (daemon.h).
425 Fixed bug #2068: pkg-config trouble
427 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
429 --- 3.0.24 2008/01/28
431 Document --with-xml2 option.
433 Added OPAC XML XSD (etc/opacxml.xsd).
435 Allow glob mask for name attribute in retrieval element for the
436 generic frontend server's retrieval facility.
438 Changed yaz_poll_poll to return yaz_poll_except for all returned events
439 except POLLIN/POLLOUT.
441 Fixed error handling in cs_listen. Bug #2037.
443 --- 3.0.22 2008/01/20
445 Fixed version in yaz/yaz-version.h.
447 Fixed bug #2027: Crash when closing connection.
449 Changed configure so that ICU support is only enabled if only ICU
450 and Libxml2 is available (because the ICU chain is XML based).
452 --- 3.0.20 2008/01/15
454 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
455 is built. Only this DLL depends on the ICU runtime.
457 yaz-ziffy is no longer part of YAZ. It is distributed separately by
458 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
460 Changed license of CCL module to 'Revised BSD'. After consultation with
461 remaining members of the original EUROPAGATE consortium, we are re-issuing
462 the CCL module without a separate license. The software was developed by
463 Index Data as part of a research project. The special license was included
464 to help feed usage information back to the project consortium to support
465 project evaluation. At this time, the project consortium has long-since
466 disbanded, and the majority of the original principals have retired. At the
467 same time, we have significantly modified the software during the following
468 years, to the point where very practically no original code remains. To
469 simplify re-use of the software, we have contacted those members of the
470 consortium who could be reached, and agreed to re-issue the module as a
471 proper part of the YAZ package.
473 Tcl scripts uses /usr/bin/tclsh as preferred shell.
475 CQL closer to being version 1.2 compliant. CQL also allows free-form
476 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
479 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
480 bug could make Extended services handling crash in the ZOOM layer. This
481 bug was only present in YAZ 3.0.18.
483 --- 3.0.18 2007/12/19
485 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
488 yaz-marcdump reads and writes collection wrapped records.
490 Handle OPAC for record conversion module.
492 Fixes for ICU wrapper.
494 Allow ICU libs to be controlled with --with-icu .
496 --- 3.0.16 2007/11/12
498 Added yaz_poll which is a wrapper for select/poll. When poll is available
499 and non-buggy, it is used, by yaz_poll . This allows more than 1024
500 sockets to be in use.
502 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
503 functionality through an XML based configuration (ICU chain). This system
504 is useful for search facilities such as Pazpar2 and Zebra that needs to
505 perform tokenization of indexed material. The ICU code in a separate
506 library libyaz3_icu.a.
508 Added HTTP tunnel facility for COMSTACK, bug #1752.
509 This is a facility that allows a Web proxy, such as squid, to tunnel
510 Z39.50 traffic. This facility is "transparent" to must applications
511 using YAZ. It's enabled by using pseudo transport connect: followed by
512 the proxy address, followed by command, then follwed by he regular
513 "virtual" addresss. For example,
514 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
516 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
518 --- 3.0.14 2007/09/21
520 Fixed bad memory reference in ZOOM_record - cuased by member not being
521 initialized. This was a problem only in YAZ 3.0.12.
523 Fixed bug in conversion from MARC to XML: Non-XML characters in control
524 fields were not removed.
526 Changed the way C code is generated from codetables.xml. Made a MARC-8
527 conversion trie for each characterSet section rather than codeTable.
528 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
529 of codetables.xml from Larry Dixson, LOC. Bug #1464.
531 --- 3.0.12 2007/09/12
533 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
534 from ZOOM_record_error).
536 ZOOM C function ZOOM_record_get returns record schema for type="schema".
538 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
540 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
542 Better SRW-to-Bib-1 diagnostic mapping.
544 ZOOM C and yaz-client announces SRU version 1.2 by default.
546 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
549 Fixed in yaz_sru_decode to allow other version than 1.1.
551 --- 3.0.10 2007/08/22
553 Added support for SRU scan for ZOOM.
555 Added support for the use of the older versions or Extended Service
556 Update in ZOOM. To faciliate this, an option "updateVersion" may be
557 set to the version , 1=first, 2=second, 3=third. The third version is
558 what ZOOM C has used so far. And that, obviously, is the default.
560 Added support for CCL queries in Z39.50 queries sent to the GFS (and
561 therefore in Zebra and in SimpleServer-based applications). The new
562 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
563 qualifier file used to transform incoming CCL queries into Type-1 RPN,
564 which is passed into the back-end search callback function.
566 Added support for HTTP Basic authentication in clients: the SRU/W
567 codec encodes the username/password elements of the PDU structure
568 appropriately, and these may be set using the "user" and "password"
569 options in ZOOM-C applications (the same options that are used for
570 Z39.50 authentication).
574 Fixed bug #1208: SSL appears to be broken in ZOOM.
576 Fixed bug #1206: Libxml2 include path weirdness.
578 Added oid_name_to_dotstring.
580 Allow elementSetName to be specified for ZOOM C record update.
582 Allow waitAction to be specified for ZOOM C based for Extended Services.
584 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
585 syntax OID. Bug introduced in YAZ 3 series.
587 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
591 Fixed bug #1157: yaz-client does not read .yazclientrc from current
592 directory. yaz-client now reads commands from file given by option -f
593 if specified; then tries to read .yazclientrc in current directory.
594 Failing that, it reads .yazclientrc from user's home directory.
596 Added support for correlationInfo Note and ID for Record Update via
599 Added yaz-client command querycharset which specifies character set for
600 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
601 (termListAndStartPoint).
603 Charset ISO5428:1984 is an alias for ISO5428-1984.
605 Implemented a way to perform scan in a result set using Z39.50. This
606 is achieved by attaching the result set name in the characterInfo
607 (type InternationalString) of OtherInformation in the Scan Request PDU.
608 The result set is identified in the otherinformation by the new OID:
609 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
610 This allows for scan in result set and faceted search . Zebra did some
611 of this in the APT term using attribute type 8 and value being result
612 set. Using the OtherInformation approach for this is cleaner and easier
613 to work with in proxies and the like. This facility can be used in
614 yaz-client using new command setscan which takes a result set as first
615 argument, start position (APT) as second.
617 Changed decoding of SRU XML packed records to deal with servers that
618 have recordData with XML data with multiple root nodes. Also make
619 comparison for recordPacking case insensitive. Again, one server
620 returns "XML" where others return "xml".
622 For SRU responses allow Content-Type application/xml as well as text/xml.
626 Fixed bug in character set conversion of BER strings. Bug introduced
631 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
633 For OID class, use oid_class consistently.
635 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
638 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
639 character set for bibliographic information interchange". By Giannis Kosmas.
641 Added documentation on new OID API.
645 Changes to generic frontend server interface: added new member
646 'query_charset' for bend_initrequest structure. A backend init handler
647 should set this member to its native character set for query terms.
648 When defined, the frontend server logic will announce this character set
649 to a client if the negotiationModel bit is set by the client. All server
650 implementors are encouraged to specify this. If a backend server does not
651 specify this a warning is issued using yaz_log(YLOG_WARN,..).
653 Added CCL utility to remove terms (stop words) from resulting RPN
654 tree. This is handled by functions with prefix ccl_stop_words_ .
656 New ZOOM C option, "rpnCharset", which allows client-side conversion of
657 terms in RPN queries.
659 Clean-up the CCL API. Moved some internal structures from ccl.h to
660 private header cclp.h. Changed ccl_parser_create so that a Bibset must
661 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
662 This is replaced by ccl_parser_find_str which takes a string instead.
664 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
665 libyaz.la is the core of YAZ except the generic frontend server and
666 does not depend on POSIX threads anymore. libyaz_server.la is the
667 generic frontend server facilities and uses POSIX thread functionality
668 if available. The libyaz.la no longer depends on POSIX threads because
669 the number of global structures is limited. NMEM no longer re-uses blocks
670 between threads ; it simply free's memory immediately but allocates in
671 "large" chunks as usual. We don't expect any performance penalties
672 because of this. The yaz_log system is still using a global log_level so
673 caution must be taken when modifying it with yaz_log_init_.. +
674 yaz_log_mask_str. This, however, should not cause any trouble because
675 these functions are called during initialization of application code
676 anyway. `yaz-config --libs server` returns libs for server applications;
677 `yaz-config --libs` returns libs for non-server applications.
679 New OID database - with public definitions in oid_db.h. Removed old OID
680 database including the head oid.h and definitions such as enum oid_value
681 and struct oident. The new OID database uses the same string names as
682 before but the 'protocol' is gone. There are now only two representations
683 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
684 converts from string to OID; functions with prefix yaz_oid_to_string
685 converts the other way.
687 Change to emit_term() in CQL-to-PQF query translation: when a term has
688 the /regexp relation modifier, do not process it for leading and
689 trailing "^" and "*", which have quite different meanings in regular
692 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
693 write handlers no longer carries a 'last' parameter. This will make
694 yaz_iconv flush "less" characters. A flush is performed by call to
695 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
697 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
698 removed, because function yaz_query_to_wrbuf does the same.
700 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
701 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
703 Deprecated MARC utility functions removed.
705 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
708 Branch split: YAZ_2_1_55_branch
710 --- 2.1.54 2007/03/16
712 Fix to ZOOM-C so that transparent reconnection is properly handled on
713 connections that are in asynchronous mode.
715 Fixed compilation on OpenBSD 4.0.
717 Large strings in GRS-1 records are now properly displayed in yaz-client.
719 Added character conversion support for "advancegreek"; based on patch from
722 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
723 sequence is met. Before the error was not set so it would be unknown.
725 Adjust yaz-marcdump MARC reader so that it skips until record separator
728 --- 2.1.52 2007/03/07
730 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
731 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
732 fd_set structure used as a bitmask for the FDs to be selected on.
734 Using ACX_PTHREAD macro to check for POSIX threads.
736 Fixed have-vsnprintf check.
738 --- 2.1.50 2007/02/23
740 Fixes for configure on BSD. Bug #900.
742 Added snprintf/vsnprintf wrappers for systems that don't have
743 limits (heavens forbid).
745 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
746 created before all previous tasks were completed and removed from the
747 task queue, the new task could be removed by a mistake.
749 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
751 Implemented pass-through CQL-to-PQF conversions. Bug #861.
753 Fixed bug #832: Problem with MARC/charset in yaz-client.
755 Fixed bug #668: save command line history for yaz-client.
757 Fixed bug #830: pkg-config support.
759 --- 2.1.48 2007/01/23
761 Extended ZOOM result set options with two options that may be read by
762 a client: resultSetStatus and presentStatus with values as specified for
764 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
766 Fixed bug #827: Using SSL fails on Debian etch.
768 Fixed bug #826: Weird looking chars for set of MARC records.
770 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
771 that is treated as an ItemOrder with itemRequest being an XML document
772 external. The value of "doc" is the content.
774 Extended the GFS search facility. New member of bend_search_rr
775 'estimated_hit_count' signals that hits is known to be an estmate
776 (higher or lower than real hit count). New member 'partial_resultset'
777 signals that the search was partial (hit count is lower or equal than
778 real hit count). For Z39.50, the information is stored in resultSetStatus
779 member of SearchResponse APDU. For SRU, the information is signalled
780 via SRU diagnostic 59: "Result set created with valid partial results
783 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
785 --- 2.1.46 2007/01/13
787 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
789 Added ZOOM_connection_peek_event.
791 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
792 the following new functions:
793 ZOOM_event_nonblock, ZOOM_connection_process,
794 ZOOM_connection_get_{socket,mask,timeout},
795 ZOOM_connection_fire_event_{timeout,socket}.
796 The existing blocking event handler, ZOOM_event, is a wrapper for the
797 + blocking ZOOM_event_sys_{poll,select}.
799 Implemented function ccl_xml_config which parses XML version of CCL
800 configuration (bug #798).
802 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
804 Added timings utility (yaz/timing.h)
806 --- 2.1.44 2007/01/03
808 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
811 Fixed bug #779: Rotation of apdu.log fails.
813 Fixed for character set conversions:
814 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
815 Honor G1 set in MARC-8 decoding.
817 --- 2.1.42 2006/12/17
819 Fixed bug #775: char conversion does not handle Alternative UTF-8
822 Implemented function yaz_marc_read_line which parses MARC line format
823 records. There is a wealth of formats out there. So far, this function
824 reads line records produced by yaz_marc_write_line.
826 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
827 more generic and easier to remember(!) options: -i format and -o format
828 which specifies input format and output format respectively - where
829 format is one of "marc", "marcxml", "line", "marcxchange".
831 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
832 does not print anything except warnings for records.
834 For yaz-marcdump, added support for MARC split into files (-s) with a given
837 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
838 spec, at http://www.loc.gov/standards/sru/record-update/
839 This has changed the binary layout of the following structs:
840 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
841 bend_update_rr . Patch by Ko van der Sloot.
843 Added GFS utility function bend_assoc_is_alive which returns 1 if
844 association is still alive (client is connected); 0 otherwise (client
845 closed connection). This allows busy servers to stop working for
848 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
849 been a separate piece of software. This version of ziffy has been modified
850 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
852 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
854 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
855 Client code may now interrogate options such as "init_opt_sort" to
856 find out whether the server claims to support various options.
858 --- 2.1.40 2006/11/27
860 Added utilities yaz_{set,get}_esn to set/get element set name from
863 Removed the build of libyazthread.la. The libyaz.so is the threaded version
864 of YAZ and has been so since YAZ 2.1.10.
866 Implemented ZOOM_record_error which returns error information for
867 record (surrogate diagnostic).
869 --- 2.1.38 2006/10/31
871 Updates for SRU Update by Ko van der Sloot:
872 1. Changed name from "operation" to "action"
873 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
874 versions in the code, marked as 'backward compatible'.
875 3. Added diagnostics for SRU Update.
877 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
879 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
881 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
883 For GFS, fixed problem with SRU diagnostic 'First record position out of
884 range' being issued for 0 hits.
886 zoomtst10 part of Windows Build.
888 --- 2.1.36 2006/10/13
890 Implemented yaz_filepath_comp which splits a path into file path
891 components (required by Zebra 2.0.3+).
893 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
894 BSD inspired license until now so this should not have any real impact on
895 anybody. See http://www.opensource.org/licenses/bsd-license.php
897 Fixed bug #687: Missing log lines.
899 Fixed bug #678: CQL to PQF translation does not preserve double-quote
902 Fixed bug #689: SRU diagnostics to be added.
904 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
905 whether a connection is idle (no more work do do).
907 --- 2.1.34 2006/10/04
909 Change type of optval from long to int for invocation of setsockopt with
910 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
912 Added support for specifying the max log file size for the Generic
913 Frontend Server. The size is given with option -r.
915 --- 2.1.32 2006/09/21
917 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
919 --- 2.1.30 2006/09/17
921 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
924 Fixed bug in Generic Frontend Server that could cause a server to stop
925 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
927 For the generic frontend server, the maximum record size is used as maximum
928 size of incoming packages (SRU + Z39.50). The value until was previously
929 only used in Z39.50 Init negotiation and, later, in a session controlled
930 sizes of records returned. This is controlled using -k option. It can be
931 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
933 --- 2.1.28 2006/09/04
935 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
938 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
940 New option for yaz-marcdump -lpos=value which allows setting a portion
941 of MARC header to a certain value.
943 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
945 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
946 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
948 --- 2.1.26 2006/08/15
950 Fixed problem with SRU mode type (soap, get, post) for yaz-client
953 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
955 --- 2.1.24 2006/08/08
957 Fixed MARC ISO2709 encoding routines to deal with character set
960 Minor changes to GFS logging. Database included in search request log
963 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
964 cached/multiple records.
966 Shared libraries are built by default on Unix+configure.
968 Changed cql2pqf transformation to use a different evaluation order. The
969 new order is: always, relation, structure, position, truncation, index
970 and relationModifier. Old order was: always, relation, relationModifier,
971 structure, index, position, truncation. Note that the the latter ones
972 override former ones for identical attributes.. The new scheme means that
973 it is possible to override any existing attribute with a relationModifier.
974 And also that it is possible to override everything for the index rule
975 (except the ones listed in relationModifier). No order is perfect but this
976 one, we believe, covers more real cases.. The "always" should have been
977 called "default", since the attributes there can be overridden with all
980 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
981 compilation phase, but also for yaz-config --cflags output. This allows
982 us to have public headers with Libxml2 stuff in them . It should also,
983 eventually, make Libxml2 checks redundant in packages using YAZ, such
986 --- 2.1.22 2006/06/15
988 Changed SRU update structure bend_update_rr so that SRU diagnostics are
989 stored in uri, message and details.. Previously diagnostics were stored
990 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
991 compatibility.. but he's probably the only one affected, so.
993 Added support for CCL, compiled on the client side, in ZOOM-C. This
994 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
995 input; the resulting query objects can be used for for searching with
996 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
998 YAZ' configure searches for OpenSSL by default.
1000 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1001 SL_CTX_use_certificate_file. See
1002 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1003 for more info. Thanks to Ko van der Sloot.
1005 --- 2.1.20 2006/06/02
1007 Bug #600: SRU GET, POST support for yaz-client. Introduced
1008 command 'sru' which selects method SOAP/GET/POST.
1010 Allow missingValueAction to be specified for the sortspec string -
1011 function yaz_sort_spec. By default, the missing value action is null.
1012 Use ! to specify "abort". Use = followed by stringvalue to specify default
1015 Ensured that Present-handler (if defined) is called in GFS before any call to
1016 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1017 searchRetrieve requests.
1019 Documentation for YAZ is now based on the Docbook XML/XSLT using
1020 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1021 is no longer depending on jade/openjade or docbook-to-man scripts.
1022 PDF is no longer part of the distribution - but can optionally be
1023 made using DSSSL/jadetex or FOP.
1025 Added retrieval handling support in Generic Frontend Server to support
1026 conversion between MARC/XML as well as XSLTtransforms. See
1027 etc/yazgfs.xml for an example.
1029 Added Authentication support to Generic Frontend Server in SRU
1030 mode. Authentication using HTTP Basic is supported, as is the use
1031 of 'x-username' and 'x-password' parameters in the request itself.
1033 Added support for a new character set MARC8s identical to MARC8 except
1034 that it converts combined characters to single Unicode characters in the
1035 Latin-1 range (when possible).
1037 --- 2.1.18 2006/04/24
1039 ASN.1 compiler 0.4: generates brief Doxygen file header for
1040 generated .h/.c files.
1042 Utility yaz_iconv now supports conversion to MARC-8.
1044 New facilities for the MARC module. The reading - and writing of
1045 content are separate methods for the yaz_marc_t handle. The following
1046 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1047 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1048 format). Write functions have prefix yaz_marc_write_.. The existing
1049 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1050 available. Removed support for OAI-MARC and simplexml (not the
1051 simplexml from PHP5).
1053 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1054 to be returned for this connection.
1056 --- 2.1.16 2006/03/31
1058 Allow multiple languages and charsets to be specified with
1059 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1060 negcharset iso-8859-1,utf-8
1062 Translation of proximity nodes from CQL into PQF now works.
1064 Moved to automake 1.8, 1.9.
1066 Added function yaz_log_set_handler which allows a log handler to be
1067 installed. This handler will be called for all log messages. Output
1068 to file is also produced; but that can be disabled by passing NULL
1069 fname to yaz_log_init_file.
1071 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1073 For SRW (including GFS), accept application/soap+xml as content-type
1076 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1077 produces NO stylesheet reference even if a default stylesheet is specified
1080 --- 2.1.14 2006/03/14
1082 Updated Windows package to include yazd.dll + yazd.lib for the
1083 Development component.
1085 If the environment variable YAZ_LOG is set, then it is used as a
1086 string indicating the default level of logging to use if not
1087 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1088 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1089 used as before. So, for example, to omit warnings from YAZ logging,
1090 export YAZ_LOG=-warn
1092 cql_transform() now map structure and other attributes before indexes,
1093 so that index-specific structures and other attributes can override
1094 defaults. So now a combination of mapping specifications such as:
1096 index.dc.date = 1=date-modified 4=5
1097 does the right thing.
1099 cql_transform() now also respects the "always" mapping specification,
1100 which establishes an initial set of attributes to be used for all
1101 terms except where overridden by more specific attributes associated
1102 with the index, relation or modifier.
1104 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1105 which mode to use; one of "post", "get" or "soap" (SRW, default).
1107 Fixes for yaz_iconv routines: changed trie-based character set conversions
1108 to use only non-negative values for bit fields due to Sun's C compiler not
1109 supporting negative values.
1111 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1112 sequences where not read correctly. Fix by Rustam Usmanov.
1114 Updated win/makefile to use options, settings which makes things
1115 compile with VS C 2005.
1117 --- 2.1.12 2006/02/01
1119 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1121 In ZOOM socket code, use select instead of poll on MacOSX.
1123 ZOOM-C now support client-side compilation of CQL into RPN that is
1124 sent to the server, enabling CQL to be used against all Z39.50
1125 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1126 ZOOM_query object, and submit it using ZOOM_connection_search().
1127 The CQL-to-RPN translation uses a configuration file, the name of
1128 which must be specified in the Connection's "cqlfile" option.
1130 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1131 function, which takes as its start-term parameter a ZOOM_query object
1132 (which may have had either CQL or RPN set into it).
1135 --- 2.1.10 2005/11/29
1137 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1138 GFS to support this as well. Backend handler, bend_srw_update, does the
1139 update work. Code contributed by Ko van der Sloot.
1141 Allow retrieval of Search Result-1 information in ZOOM by the use of
1142 options that are attached to a result set. ZOOM documentation updated
1145 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1146 UTF-8 conversion. Patch by Raj Patel.
1148 Added option -m to GFS to control formatting of timestamps in log file.
1150 Added 'exit' as synonym for 'quit' in yaz-client
1152 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1153 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1154 for the new members. Patch by Ko van der Sloot.
1156 Added support for SRU POST. It is supported for content-type
1157 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1159 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1160 Instead make the library libyaz.la multi-threaded. Threading as a whole
1161 can still be disabled by configure option --disable-threads. Previosly,
1162 with older GLIBCs there were problems with MT libs under Apache. This
1163 has now been fixed a long time ago.
1165 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1168 CQL module modified to be case insensitive for relations/indexes/operations.
1170 Fixed bug in CQL transform code: incorrect value relationModifieder
1173 Added 'show all' command for yaz-client which retrieves all results
1176 Added new yaz-client, xmles, which takes a (private) OID and
1177 a document to be sent as an extended service request.
1179 Describe new yaz-client commands wait_response and set_auto_wait.
1181 Increase TCP/IP listener backlog from 3 (which I am guessing was
1182 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1183 that the socket will queue as many incoming connections as it's able
1184 to handle ongoing connections. In other words, it will never now
1185 refuse a connection that it would be able to handle merely because
1186 it's not got around to accepting() enough of the pending connections
1187 yet. This is the behaviour anyway under Linux, where the listen()
1188 argument is ignored; but not under BSD and on systems such as
1189 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1190 YAZ-based servers should now be uniform across operating systems in
1193 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1194 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1195 This allows yaz-marcdump to read large MARC batches (>2 GB).
1197 Modified all YAZ source files - except the source which is auto-generated
1198 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1201 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1202 corresponding to the existing *_setl() function. These allow option
1203 values containing arbitrary valuues.
1205 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1206 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1207 except that it returns an indicator of whether or not the sort
1208 criterion was accepted (0 for OK, -1 for invalid).
1210 --- 2.1.8 2005/06/07
1212 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1213 MARC output rather than returning "new" buffer.
1215 yaz-client warns about unknown init options.
1217 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1219 --- 2.1.6 2005/05/24
1221 Added support for SRW sort in Generic Frontend Server. Patch
1222 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1223 sortKeys - or NULL if none is provided.
1225 Fixed bug #307: It was impossible to specify indefinite/no timeout
1226 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1229 Added support for multiple languages and charsets to be specified in
1230 ZOOM. Each charset/language is separated by a blank. If negotiation is
1231 in effect in init-response, Option
1232 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1233 Code based on patch by Vasiliy Osadchuk.
1235 Fixed bug #306: infinite recursion that occurred when calling
1236 yaz_log_level_init as the first call (before other log level or
1239 Fixed bug in scan handling in front end server: if preferred-Position-In-
1240 Response was non-present, a NULL pointer referece was performed.
1242 --- 2.1.4 2005/04/26
1244 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1245 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1246 now defined for all those error codes. So instead of putting 109 in
1247 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1248 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1250 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1253 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1255 Program yaz-client now exits and produces an error message if multiple
1256 Z39.50 servers are specified on the command line (none or one allowed
1259 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1262 --- 2.1.2 2005/03/16
1264 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1266 Fixed bug #272: Preserve spacing for CCL terms.
1268 --- 2.1.0 2005/03/14
1270 Added support for virtual hosts and multiple backend servers for
1271 the YAZ frontend server. The configution is XML based and
1272 support specificition of CQL to RPN mappings and explain information.
1273 See section "Virtual Hosts" in the YAZ manual.
1275 Extended OPAC display utility. OPAC display utility renders
1276 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1277 to supplement yaz_marc_decode_wrbuf.
1279 Fixed a bug in MARC decoder that could caused it to crash for some
1280 invalid MARC records. More diagnostics and warnings where added in
1281 XML output (warnings, etc are stored in comments).
1283 --- 2.0.34 2005/02/08
1285 Fixes for UNIX domain sockets. Bug #261.
1287 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1289 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1290 Added yaz_marc_subfield_str which defines subfield lead string which is
1291 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1292 yaz_marc_endline_str which defines end of fields string used in
1293 YAZ_MARC_LINE format. Default string is newline.
1295 Experimental support for MarcXChange. This format can be produced
1296 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1297 http://www.bs.dk/standards/MarcXchange.xsd
1299 Added yaz-client commands scansize that sets maximum number of
1300 entries to be returned by scan.
1302 --- 2.0.32 2005/01/11
1304 Added support for SRW scan in yaz-client and Generic Frontend Server.
1306 * Added whereInList member to SRW Scan Term.
1308 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1310 Fixed NMEM system to return aligned blocks on the smallest boundaries
1311 that are suitably aligned for all possible types on the particular
1312 architecture YAZ is being built for.
1314 --- 2.0.30 2005/01/04
1316 Fixed numerious warnings that was issued with newer versions of GCC.
1318 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1319 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1322 Make YAZ Generic Frontend Server slightly faster.
1324 Enhance (and reduce) logging for Generic Frontend Server.
1326 Revert YAZ log system so that it flushes every write operation
1327 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1329 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1330 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1331 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1332 will effectively disable old definitions.
1334 --- 2.0.28 2004/11/09
1336 Added yaz_log_time_format which specifies log format using
1339 Added yaz_log_module_level which returns mask for a module. Value
1340 is non-zero mask a if module is enabled; zero if disabled.
1342 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1343 in include/yaz/cql.h.
1345 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1347 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1349 Fixed bug #172: RPM builds does not enable SSL.
1351 Doxyfile.in part of dist. Doxyfile generated by configure.
1353 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1354 are given and the corresponding component does not exist.
1356 Extend CCL documentation in YAZ reference. Describe r=r.
1358 --- 2.0.26 2004/10/01
1360 Fixed MARC->MARCXML conversion to properly deal with
1361 fields, subfields, indicators having non-ASCII characters.
1363 Fixed MARC->MARCXML conversion so that ASCII control characters
1364 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1367 Added YAZ GFS support for conversion from Z39.50 surrogate
1368 diagnostics to SRW surrogate diagnostics.
1370 Bug fix: YAZ GFS did not return schema in explainResponse.
1372 --- 2.0.25 2004/09/30
1374 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1375 now converts recordSchema to elementSetName as well as schema URI.
1377 Fixed bug in COMSTACK that prevented HTTP request packages from being
1380 --- 2.0.24 2004/09/29
1382 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1383 does not require white-space before and after the dash in a range, e.g.
1384 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1387 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1388 due to new GCC removing "redundant" code.
1390 Added yaz-client commands scanpos and scanstep that sets preferred
1391 position and step-size for scan.
1393 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1395 Added CCL utility ccl_qual_buf which parses one or more CCL
1396 spec lines in a buffer.
1398 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1399 of name and value - ignoring empty lines and comments.
1401 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1403 Added odr_get_element_path which returns current element path for an
1404 ODR handle. This utility is useful in error handling or user-defined
1407 Added ODR_PRINT utility odr_set_stream which is is a more generic
1408 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1409 to a write function and pointer to close function. The close function - if
1410 non-NULL - will be called during odr_destroy.
1412 Fixed bug in CCL parser where truncation char was not removed from
1413 right side when truncation=both was in effect.
1415 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1418 --- 2.0.23 2004/08/11
1420 Fix buffer overrun in CQL parser when dealing with proximity (%).
1422 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1423 to UTF-8/UCS conversion is now only based on codetables.xml.
1425 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1427 --- 2.0.22 2004/08/06
1429 Add support for more "commit changes" in ZOOM (uses Extended Services).
1431 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1434 Yet another small fix for configure of SSL.
1436 --- 2.0.21 2004/05/14
1438 Fix SSL libs for configure when --with-openssl=DIR is given.
1440 --- 2.0.20 2004/05/10
1442 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1444 SSL comstack now uses yaz.pem certificate file on server side
1445 by default. Certificate filename can be configured by calling
1446 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1448 Fix bug regarding multiple calls to ZOOM_connection_connect.
1450 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1452 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1453 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1455 ZOOM now allows inspection of X509 peer certificate for verification.
1456 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1458 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1459 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1460 as "modular" but it simplifies things.
1462 Added cs_get_peer_certificate to that returns peer X509 PEM.
1464 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1465 NULL if SSL is unavailable.
1467 Documentation about MARC decoding tools.
1469 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1471 --- 2.0.19 2004/03/30
1473 Rename CHANGELOG to NEWS to follow GNU style packing.
1475 Fix bug with missing initialization of member in init_diagnostics.
1476 This bug affects threaded version of GFS server.
1478 --- 2.0.18 2004/03/20
1480 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1483 Ensure zlib.dll is packed with Windows install.
1485 --- 2.0.17 2004/03/17
1487 Fix encoding of xsd:string to use text instead of CDATA.
1489 Fix endless loop in CQL parser with unbalanced ".
1491 Use a more compact way to store MARC-8 conversion tables.
1493 --- 2.0.16 2004/03/16 Debian only
1495 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1498 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1503 --- 2.0.15 2004/03/01
1505 Another fix for decoding of XML packed records.
1507 --- 2.0.14 2004/02/25
1509 Fixes for Chunked encoding. White space not ignored after length spec.
1511 Update NS and use default NS for SRW diagnostic elements.
1513 --- 2.0.13 2004/02/23
1515 Implement ZOOM_resultset_cache_reset which resets record cache.
1517 Implement ZOOM_resultset_sort which sorts a result set.
1519 Implement chunked HTTP transfer.
1521 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1523 --- 2.0.12 2004/02/16
1525 Added member 'schema' to bend_explain_rr structure so that backend
1526 can specify explain record identifier. Defaults to Zeerex 2.0.
1528 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1530 --- 2.0.11 2004/02/16
1532 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1535 Added init command for yaz-client which sends "extra" init request.
1537 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1538 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1540 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1542 Make ZOOM error code for "invalid query".
1544 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1546 --- 2.0.10 2004/02/05
1548 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1551 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1553 Added option -p <file> to make Generic Frontend Server to write PID file.
1555 Added option -D to put Generic Frontend Server in background on its own.
1557 Make ZOOM C recognize option "password". If unset, "pass" is used
1558 (for backwards compatibility).
1560 Fixed a bug in Generic Frontend Server that could make it crash if a
1561 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1564 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1565 Must be issued before open, in order to be in effect.
1567 --- 2.0.9-6 2004/01/12 Debian/Windows
1569 Make the SRU server more picky WRT unknown params, etc.
1571 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1573 New YAZ client command, options, that sets Z39.50 options.
1575 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1576 options from a string of tokens (one token for each option bit).
1578 Update SRW diagnostic code messages.
1580 --- 2.0.9-5 2004/01/07 Debian/Windows
1582 Handle user defined stylesheet for SRW/SRU.
1584 --- 2.0.9-4 2004/01/06 Debian/Windows
1586 Fix bug in decoding of Content-Length.
1588 --- 2.0.9-3 2004/01/06 Debian/Windows
1590 Fix a bug with decoding of XML packed records.
1592 --- 2.0.9-2 2004/01/05 Debian only
1594 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1596 Fix bug in SRW/SRU diagnostics decoding.
1598 --- 2.0.9 2004/01/05
1600 Fixed bug in Generic Frontend Server which could drop records exceeding
1601 preferred message size. Reported and fixed by Irina Dijour.
1603 Fixed calculation of package size for structured records in Generic
1604 Frontend Server. Reported and fixed by Irina Dijour.
1606 Fixed namespace for SRW/SRU diagnostics.
1608 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1610 --- 2.0.8 2003/12/22
1612 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1613 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1616 CQL changes to reflect recent changes to the specification:
1617 * Documentation talks about context sets instead of index sets.
1618 * Documentation talks about indexes instead of qualifiers.
1619 * The CQL-to-PQF transformer's configuration file now uses
1620 "index.set.name = <attributes>" instead of the old form
1621 "qualifier.set.name = <attributes>". (Both forms are still
1622 understood but the latter is deprecated.)
1623 * CQL terms with no explicit index specified are now interpreted as
1624 cql.serverChoice instead of srw.serverChoice (which of course
1625 behaves exactly the same.)
1627 --- 2.0.7 2003/12/16
1629 MARC conversion can now generate ISO2709 output in another
1630 character set. yaz-marcdump uses this facility if you invoke it
1633 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1634 functions from there can be used from C++.
1636 --- 2.0.6 2003/12/04
1638 Frontend server now transfers memory from decoded packages to stream
1641 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1642 references to show up.
1644 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1645 the ZOOM Abstract API. The older names for the same options are still
1646 also supported for the benefit of old applications.
1648 ZOOM-C supports "implementationId" and "implementationVersion" options
1649 to go along with "implementationName". These allow the user code to
1650 specify identification strings to be sent to servers.
1651 Add OID for the new ExtLite attribute set.
1653 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1654 as requested/supplid by Ere Maijala <ere@atp.fi>
1656 For generic frontend server, reverse the order of
1657 "toolkit-supplied / application-supplied" strings sent as implementationId,
1658 Name and Version. Also, remove the spaces around the slash. This brings
1659 the GFS in line with the behaviour of ZOOM-C on the client side.
1661 Add function ZOOM_scanset_display_term.
1663 yaz-client shows scan displayTerm if present.
1665 Utility yaz-iconv is now installed by default along with the man page
1668 Extend configure check for OpenSSL to use pkg-config where available (such
1671 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1672 server to specify uid/gid/mask for socket using the format
1673 unix:[user=uid,][group=gid,][umask=mask,]file=path
1674 If file= is omitted the existing format is assumed, e.g.
1676 in which case the mask is 0666 (rw for everybody).
1678 Major restructure of YAZ source. All source in libyaz is in src directory.
1679 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1680 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1682 Added man page for utility yaz-marcdump (used to be called marcdump).
1683 yaz-marcdump is installed by 'make install'.
1685 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1686 of incoming package failed.
1688 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1690 Change prototype of odr_perror: add const to message string.
1692 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1694 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1695 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1696 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1697 DNS lookup. There should not be any compatibility problems with this
1698 assuming that blocking=1 or 0 is used.
1700 Fix bad reference in UNIX comstack in function cs_addrstr.
1702 Fix for compilation on AIX.
1704 The generic front-end server (server/seshigh.c) now supports returning
1705 Init diagnostics to the client in User-information-field, in
1706 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1709 --- 2.0.4 2003/09/04
1711 Allow any CQL relation (not just all,any,exact,scr).
1713 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1714 that features the same UI.
1716 Implemented command update0 in YAZ client which is equivalent to
1717 update but uses old of Ext Update ASN.1.
1719 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1720 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1721 Previously no OID was used for this info.
1723 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1724 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1725 returns 'malformed search term' otherwise.
1727 SortResponse member resultCount now set to NULL in sort handler of
1730 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1733 Add three new utility functions for translating OIDs between various
1734 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1735 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1736 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1737 char *oid_to_dotstring(const int *oid, char *oidbuf);
1738 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1740 Reverted modifications for ES Update definition for z_IU0Update
1741 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1742 is back to YAZ 2.0.2.
1744 String value attributes for CCL parser.
1746 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1747 which their FirstSearch server returns in Init responses, sometimes
1748 carrying useful diagnostic information when Init fails. This has the
1749 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1750 "z39.50/oclcui.asn", where its definition is somewhat different from
1751 what OCLC document on their web-site, as required to interoperate with
1754 Support for anonymous authentication in yaz-client. Use the command
1757 * Fix the OID of the Index Data-local "admin" Extended Service from
1758 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1759 the 1000, which indicates a locally-defined OID, was a mistake.
1761 --- 2.0.3 2003/06/20
1763 Fix CCL directive @case handling so that it affects string match for
1764 both CCL keywords and qualifiers.
1766 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1767 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1768 Decoder has been updated with ASN.1 changes as listed in
1769 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1770 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1771 z_IUUpdate, remains unchanged.
1773 ZOOM_record_get may now return a record in a specific character set.
1774 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1775 "from" is the character set of record as returned by target. "to" is
1776 the character set to be returned. If omitted, "to" is UTF-8.
1778 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1780 New ODR utility, odr_getelement, which returns name of element for
1781 which encoding/decoding failed.
1783 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1784 in cases where a required element was omitted.
1786 Bug fix: some MARC8 sequences were not converted.
1788 New ZOOM option "step" which specifies number of records to be
1789 retrieved in one chunk. Used in conjunction with "start" and "count".
1791 SRW support for yaz-client. Use scheme http: to use it, e.g.
1794 yaz-client no longer does (un)intelligent character set conversions
1795 by default. Can be enabled with charset and marc_charset commands.
1797 xmalloc trace fix for 64-bit systems such as DEC alpha.
1799 Solaris 2.6 compile fix.
1801 New function, cql_strerror() translates SRW error codes, as returned
1802 by cql_transform_error(), into human-readable English strings. Used
1803 in yaz-client diagnostics when appropriate.
1805 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1806 converts it into a type-1 query which is sent to the server. This
1807 makes CQL available for use with all Z-servers, as opposed to the tiny
1808 minority that can handle CQL queries themselves.
1810 --- 2.0.2 2003/04/28
1812 New Debian package layout similar to the Redhat Package layout.
1814 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1815 and search result respectively.
1817 --- 2.0.1 2003/04/25
1819 Redhat package is now several packages: libyaz (runtime libraries),
1820 libyaz-devel (development and documentation, and yaz (utility programs).
1821 Package spec file by Morten Bogeskov.
1823 New member 'schema' in struct bend_fetch_rr which the name of requested
1824 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1825 handler MAY set this to reflect the schema of the returned record.
1827 New member 'display_term' in struct scan_entry. GFS now sets member entries
1828 and allocates scan entries to be filled by user scan handler. In previous
1829 version, entries member was allocated by the scan handler. That still works,
1830 but the GFS will ignore member display_term - assuming it was NOT set by
1831 the handler. The fact that the GFS now allocates the entries both allows
1832 for new members and makes a scan handler easier to write.
1834 Fix CQL lex buffer overflow.
1836 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1837 SRU default recordPacking is string.
1839 SRU protocol support for frontend server.
1841 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1843 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1845 Added scan for the ZOOM shell (zoomsh).
1849 * String Identifers for Schemas (Amendment 5).
1850 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1851 Old definition for schema
1852 Odr_oid *schema; /* OPT */
1857 Z_InternationalString *uri;
1858 #define Z_Schema_oid 1
1859 #define Z_Schema_uri 2
1862 * resultCount parameter to Sort Response (Amendment 1).
1863 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1865 Support for SRW 1.0 over HTTP. This is an optional feature and
1866 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1869 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1870 on the same port. SRW SearchRetrieveRequests are mapped
1871 to bend_init,bend_search,bend_fetch,bend_close.
1873 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1875 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1876 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1878 ZOOM connections are SRW based if schem http is used for hostname
1879 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1880 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1882 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1883 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1884 distance=n, order=true/false, relation=le, prox unit=word. If
1885 n is omitted, distance 1 is used.
1887 Fixed problem with C compiler include path in wrong order.
1889 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1890 on Solaris. Patch from Ko van der Sloot.
1892 New MARC decode API. All new functions operate on a yaz_marc_t
1893 handle. The most important new functions are: yaz_marc_create,
1894 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1895 decode and destroy respectively. Decoder can produce formats
1896 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1897 include/yaz/marcdisp.h.
1899 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1900 to UTF-8, UCS-32, wchar_t or Latin-1.
1902 * Prototypes for yaz_iconv_-functions moved to separate header
1903 include/yaz/yaz-iconv.h.
1905 Make a few private functions 'static' in unix.c. This prevents
1906 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1908 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1909 are set when Init Response is received.
1911 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1912 but returns diagnostic set as well.
1914 New function yaz_strerror which is a portable wrapper for
1915 strerror/strerror_r/GetLastMessage.
1917 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1918 is returned for MARC. If type is "oai", then OAI MARC is returned.
1920 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1923 --- 1.9.2 2002/11/26
1925 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1927 Fix bad race conditions on SIGTERM and terminate gracefully in
1930 Move retrieval (data1) module to Zebra since nobody seems to be
1933 Add GRS-1 render for ZOOM using same format as yaz-client.
1935 --- 1.9.1 2002/10/05
1937 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1939 Fix broken ESpec handling in data1 module.
1941 SGML reader parses comments and makes them part of the data1 tree.
1943 Added several type casts so that YAZ compiles as C++ code.
1945 ZOOM didn't handle PDU encoding failures properly.
1947 Added more Bib-1 diagnostics (approved extensions).
1949 GNU configure: better check for iconv.
1951 More portable use of accept, getpeername. Check for socklen_t. Use
1952 int/size_t if socklen_t is not defined.
1956 PQF parser rejects bad queries - including those with extra
1957 characters in them. PQF parser used to silently ignore that.
1958 Cleaner API for PQF added, which allows you to get detailed
1959 error information for bad queries (see yaz/pquery.h).
1961 Fixed bug in ZOOM_record_get for type "database".
1963 Implemented mini iconv library supporting conversions between
1964 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1966 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1968 --- 1.8.9 2002/08/20
1970 Fixed ZOOM C record cache so that preferredRecordSyntax and
1971 elementSetName is used to check for already fetched records.
1973 --- 1.8.8 2002/08/02
1975 Added three members in bend_initrequest structure to facilitate
1976 character set negotiation.
1978 Fixed a bug in frontend server that could cause indefinite
1979 loops under rare conditions.
1981 Revised character set utilities (charneg.h) so that encoding
1982 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1984 For PQF, directive @term <type> sets term type for Scan/Search.
1985 Here <type> is general, string, numeric, null. The term type
1986 is inherited - just like @attr.
1988 New call odr_set_charset that sets character set conversion for
1989 international-strings on a ODR stream. Prototype is:
1990 int odr_set_charset(ODR o, const char *to, const char *from);
1991 The InternationalString is still represented as C string in YAZ
1992 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1993 won't). On the protocol level, you can use any encoding.
1995 Support for UNIX sockets in ZOOM.
1997 Solaris recv sometimes returns errno == ENOENT. It is treated as
1998 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2000 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2001 both client and server. Code by Morten Bogeskov.
2003 --- 1.8.7 2002/05/22
2005 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2006 that they can be used directly from Visual Basic. You must recompile
2007 your windows APP if you're using ZOOM.
2009 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2010 Commands "lang" and "charset" sets language and character set respectively.
2011 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2012 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2014 Attributes from multiple CCL fields may be OR'ed rather than merged
2015 using directive "@field or". Fields are still merged by default -
2016 equivalent to "@field merge".
2018 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2021 Fixed bug in zget for parameter ExtendedServicesResponse.
2025 --- 1.8.6 2002/03/25
2027 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2029 Client displays USR.1:SearchResult-1 (hits per term).
2031 Additional Search Info for search in Generic Frontend Server.
2033 Fixed CCL parsing of "field=s".
2035 WIN32 installer - using the excellent NSIS software from nullsoft.
2037 Fixed CCL parsing of "field = - <number>".
2039 Added function yaz_marc_decode that decodes MARC for line mode
2040 display or XML (similar to that used by JZKit).
2042 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2043 Z39.50. But ISO/ILL was, however.
2045 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2046 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2048 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2049 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2051 --- 1.8.5 2002/02/03
2053 New YAZ client features: Command completion and new commands:
2054 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2055 Code provided by Jacob Poulsen.
2057 New call oid_trav, that visits all registered OIDs via callback.
2059 Function ZOOM_record_get now returns const char pointer rather than
2060 void pointer. It saves a lot of type casts.
2062 For YAZ client, command "auth" now allows you to set authentication
2063 in IdPass style. It is enabled when three tokens are given - order
2064 is user, group and password.
2066 Fix memory leaks in MARC record handling for ZOOM.
2068 New option for YAZ client, -k <kilobytes> that sets
2069 maximum record size. Similar to -k option for generic frontend
2070 server and yaz-ztest.
2072 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2074 Prefix query parser reports "fail" when bad attribute set is given.
2076 Fix in MARC decoder. Proximity logging. Fix for attribute set
2077 in scan handler for server. Patches by Shigeru Ishida.
2079 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2082 Configure option --with-openssl=<dir> now works when a directory is
2083 specified. Patch provided by Morten Bogeskov.
2085 New option for YAZ client, -u <auth>, that sets authentication.
2087 ZOOM fix: error information was sometimes "missing", since error
2088 was cleared/reset too when it shouldn't.
2090 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2092 --- 1.8.4 2002/01/04
2094 Scan for ZOOM API. New object ZOOM_scanset. New functions
2095 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2096 ZOOM_scanset_destroy.
2098 New ZOOM function, ZOOM_connection_last_event, that returns type
2099 of last event (such as "receive data", "send data", "apdu received",
2102 New ZOOM option, schema, that specifies schema for retrieval.
2104 New CCL feature. Qualifiers can be aliases for one or more
2105 other qualifiers (if more than one is given, OR is used).
2107 ZOOM uses named result sets if target supports it.
2109 Two new YAZ client commands: . (dot, which sources a script of YAZ
2110 client commands), and ! (to execute shell command.). Implemented
2113 Working on Debian packages.
2115 --- 1.8.3 2001/11/19
2117 YAZ client enables named result sets only if target supports it.
2119 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2121 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2122 with key="host" to get same result.
2124 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2125 Function Z3950_resultset_record(s) returns references to records
2126 "owned" by resultset. To become owner use Z3950_record_clone.
2128 Function z_ext_record handles Extended Services. Thanks to
2131 --- 1.8.2 2001/11/12
2133 CCL Parser fix: ignore token comma when dealing with and-lists.
2135 Documentation updates for COMSTACK.
2137 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2138 Changed prototype Z3950_records. For some functions, int parameters
2139 were changed to size_t.
2141 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2144 New MARC decode/display function, marc_display_exl, which properly rejects
2145 non-ISO2709 records. YAZ client uses it.
2147 --- 1.8.1 2001/10/29
2149 Fix bug: local attribute set wasn't set correctly in PQF strings.
2153 * Old Z39.50 codecs no longer supported.
2155 Added ZOOM C binding. See http://zoom.z3950.org/
2157 Renamed states for COMSTACKs to avoid confusion with events.
2159 Implemented cs_look and proper cs_rcvconnect.
2161 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2163 Configure detects POSIX threads on OpenBSD.
2165 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2166 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2168 When error is returned from present handler, non-surrogate diagnostic
2169 is returned in present response (and fetch handler is no longer called).
2171 * Minor adjustments to pquery parser (PQF). Token characters may be
2172 escaped by using backslash (C-style).
2174 PQF parser allows string attribute values to be specified. For @attr,
2175 non-numeric characters after the equal-sign are treated as strings
2176 (e.g. @attr 9=title).
2178 CCL trunction character may be defined (@truncation in file)
2180 * function zget_ExtendedServicesRequest sets waitAction to
2181 waitIfPossible (was wait).
2183 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2186 CCL operator names may be set in field definition files (CCL_bibset).
2187 See ccl/bib1 for an example.
2189 Fixes in ASN.1 compiler for C++ compatibility.
2191 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2192 and "op_or" to avoid conflict with C++.
2194 Fixed problem with GNU readline detection on Redhat 7.0.
2196 Added step-size for Scan backend handler.
2198 Fixed bug that made the frontend server crash when no attribute
2199 set was specified for scan.
2201 Front-end server automatically switches to original working directory
2202 when installed as an NT service. Previously -w had to be specified to
2205 Added extended attributes for retrieval module (data1), so that data1
2206 records carry d1_readXML/SGML attributes. d1_read also supports
2207 null-data rules ( <tag/>)
2209 On UNIX when POSIX threads are available, a separate library libyazthread
2210 is created. Programmers should link with that library and the yaz library
2211 when using threads. The reason for the split was that some applications
2212 on Linux, such as Apache, doesn't work well when using shared objects that
2215 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2216 (or any frontend server) in SSL mode by specifying ssl: followed by
2217 address. Only tested on UNIX.
2219 Added feature for CCL module. Virtual structure s=al or s=ol generates
2220 and-list and or-list respectively instead of phrase search.
2224 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2225 log_mask_str. This was done to avoid name conflicts with other libraries
2226 (such as other PHP extensions).
2228 Added raw OID member for preferred record syntax (request_format_raw)
2229 and returned record syntax (output_format_raw) for backend fetch method.
2231 Config file yaz-config now accepts options so that it returns specific
2232 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2234 Shared library support for UNIX using GNU libtool.
2236 * Modified backend interface. Request/Response struct's replaced by
2237 one read/write C struct. For example bend_fetchrequest and
2238 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2239 Every handler - even search has to be registered in bend_init
2240 handler. This means that the YAZ library no longer refers to
2241 external functions and it makes it possible to make the whole
2242 thing a single DLL/SO.
2244 Added Segment handler for backend server.
2246 Added Zmbol/Zebra administrative functions to YAZ client.
2248 Threaded frontend server on UNIX (when POSIX Threads are available).
2249 Starting the server with option -T enables multi-threading.
2253 Added configure option --enable-comp/disable-comp to control use
2254 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2255 located in sub directory asn.
2257 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2258 in ${exec_prefix}/bin along with the other programs yaz-client and
2261 GNU automake used to maintain makefiles.
2263 Added several OID's.
2265 Changed retrieval module so that we can load records with no abstract
2266 syntax defined. Tagpaths in these records are fully composed of string
2269 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2273 On UNIX, the generated makefile now supports a proper 'make install'.
2274 The prefix can be set via GNU configure to set the install location
2275 (default is /usr/local).
2277 * YAZ programs client and ztest were renamed to yaz-client and
2278 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2279 locations, such as /usr/bin,/usr/local/bin,etc.
2281 * YAZ Header files were moved from include to include/yaz. YAZ Header
2282 files are referred to as include <yaz/log.h> rather than <log.h>.
2283 The YAZ include path (-I ..) is therefore the same as before. Programmers
2284 should update their #include statements or use -Ipath/include/yaz
2285 instead. The main motivation for doing this change is that YAZ header files
2286 can be installed in "standard" locations /usr/include,/usr/local/include
2287 without introducing conflicts, since ALL YAZ header files are stored
2288 in subdirectory yaz (under /usr/include for example).
2290 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2291 rather than project/workspace files. We switched because project files
2292 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2295 Changed name of logging function, logf, to yaz_log, to prevent name
2296 clash with some math-log functions. The YAZ header log.h defines logf
2297 to yaz_log (#define) so there should be no incompatibilities by this
2300 Added bend_start/bend_stop handlers for server. These handler are
2301 called on start/stop of server. For windows they are called whenever
2302 a service is started/stopped.
2304 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2305 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2306 in util/yc.tcl. The auto-generated C code structures are, in a few
2307 cases, incompatible with the old decoders. There are differences in the
2308 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2309 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2310 The preprocessor variable ASN_COMPILED is defined when the compiled
2311 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2312 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2313 wish to use the old encoders/decoders you can specify --disable-yc
2316 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2317 version so that it supports both new - and old version of DB Update
2319 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2320 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2321 change. The name parameter can be set to 0 in which no name is specified
2322 for the construction. The macros odr_implicit and odr_explicit sets name
2323 parameter to zero for the construction involved. New macros
2324 odr_implicit_tag and odr_explicit_tag are similar to the others,
2325 except that a name parameter is added. For programmers' that don't use
2326 ODR they probably only need to change the call to z_APDU and z_External.
2328 Added access control facility by interfacing the TCP wrapper library.
2329 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2330 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2331 name of the daemon and enables the access control as specified in
2332 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2334 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2335 den Dool <H.M.vdnDool@kub.nl>.
2337 Added reference ID parameter to most functions in server API - refer
2338 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2340 Changed name of ccl library to libccl.a (was ccl.a).
2342 Fixed bug in decoder for Explain (Category TargetInfo).
2344 Added support for GNU readline in client. Thanks to Jacob Poulsen
2345 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2347 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2348 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2349 IMPLEMENTATION! This change was made to the development version before
2350 the ZIG decided to retract the amendment. If any users MUST be
2351 compatible with the original Update definition, PLEASE CONTACT US, and
2352 we will include a separate definition corresponding to the old Update
2353 ES. Note that because of the change to the ASN.1 of the
2354 TaskPackageRecordStructure we cannot define a single structure that
2355 will support both versions.
2357 * Added const modifier to buffer parameter for some ODR/BER encoding
2358 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2359 completeWAIS, odr_dumpBER.
2361 Fixed bug in client.c which caused a crash when a scanResponse didn't
2362 contain positionOfTerm.
2364 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2365 * will cause an error in a client if a non-YAZ target sends both a
2366 * list of Scan entries and non-surrogate diagnostics.
2368 Retrieval module enhancements. Tag sets may be typed in the reference
2369 to it. From the .abs-file the "tagset" directive takes a third optional
2370 integer type for the tag set referenced. From a .tag-file the "include"
2371 directive takes a third optional type as well. The old "type" directive
2372 in the tag set itself is still recognized but acts as the default type
2375 Backend interface change. Individual Scan terms returned from bend_scan
2376 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2377 in include/backend.h.
2379 Retrieval module enhancements. Multiple tag sets and attribute sets may
2380 be specified in abstract syntax specs. Revised the error/warning for
2381 logging messages reported by the retrieval module when reading the
2384 Object Identifier system (oid_..) changed. The API is backwards
2385 compatible but the oid-routines now allocates new OID's when needed.
2386 Raw OID's may be specified in oid_getvalbyname.
2388 YAZ now uses GNU configure to generate Makefile(s).
2390 * Minor changes in some of the member names of DeleteResultSetRequest and
2391 DeleteResultSetResponse. See include/proto.h.
2393 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2394 and added member 'languages' in TargetInfo (which was missing).
2396 Changed the way attribute sets are handled in the retrieval
2397 module. These are now cached, just like the abstract syntaxes
2400 Changed YAZ so that it links with compiled ASN.1.
2402 Added Explain-schema definitions and mapping routines. The following
2403 Explain categories have been implemented: AttributeDetails,
2404 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2406 Fixed minor bug in Windows version of Server Library.
2408 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2410 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2412 Added EXTERNAL: UNIverse Resource Report (non-standard).
2414 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2415 ENUMERATED and SET OF.
2417 * Added 'const' to some of the char pointer arguments for the
2418 functions, data1_read_node, data1_getelementbytagname,
2419 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2422 Fixed bug in data1_insert_taggeddata - the last_child member of
2423 parent wasn't initialised.
2425 * Changed data1_read_record and data1_read_node so that the supplied
2426 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2427 doesn't refer to any parts of the "SGML"-buffer.
2429 Fixed bug in server library (Windows version of statserv_remove).
2431 * Changed code so that it compiles as C++. The type definition
2432 of Odr_fun which is a member of Odr_arm was changed. The result is,
2433 that an explicit typecast is needed for the fun pointer when
2434 using Odr_arm - as in:
2435 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2437 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2439 Implemented the new structured date and time definition as approved
2440 by the ZIG. Added schemaId element to the specificTag in Espec-1
2441 (also approved at the last ZIG). Thanks to RVDM.
2443 Added some Object identifiers (RVDM).
2445 Changed the Update Extended Service (RVDM).
2447 Added command "refid" to client which specifies referenceId for
2448 the following requests.
2450 Implemented extended service handling for server. See ztest.c
2451 for an example as well as backend.h. New handlers are registerd
2452 in the Init handler.
2454 * Changed interface for sort in server.
2456 Added new members to statserv_options_block. It allows a server
2457 to read options from another source than just the command line. Thanks
2458 to Charles Woodfield.
2460 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2461 renamed to zboolean. Some C++ compilers complained about the name.
2463 Minor changes to gils.abs. Added index 's' (sort) on title
2464 and date/time-last-modified.
2466 --- 1.4pl2 1998/1/30
2468 Fixed bug in server library regarding inetd mode (-i). This bug
2469 was introduced by release 1.4.
2471 --- 1.4pl1 1998/1/29
2473 Added sort facility in client and backend server interface.
2475 Fixed problem with dependencies in Makefile(s).
2477 Fixed bugs for encoders/decoders of extended services and
2480 Implemented sub-tree feature for schemas. Sub-trees are
2481 referenced in *.abs-files. See explain.abs for an example
2482 of the use of this feature.
2484 Modified bib1.att; local attributes for ANY didn't include
2485 ANY itself (only affects use of the retrieval module).
2487 Fixed bug in plain SGML reader in function data1_read_node:
2488 tags with prefix "var" was incorrectly interpreted as variants.
2490 Added feature "sub-schemas" to enable references to - and definitions
2491 of - group of elements.
2493 * Removed member parent from type data1_element (in data1.h).
2495 Implemented function odr_nullval() that returns the value of
2498 * Removed member num_children from data1_node (in data1.h).
2500 Made NT service interface part of the server library. The
2501 function statserv_main uses the NT service when required and
2502 calls the statserv_start / statserv_close routines.
2504 Routine zget_SearchRequest and zget_PresentRequest fills
2505 resultSetName/Id member with "default" instead of "Default".
2507 Fixed memory leak in server. Request queue member wasn't freed.
2509 Fixed nmem_exit so that memory is freed.
2513 Revised the CCL parser utility to be thread safe.
2515 Added function, oid_ent_to_oid, to replace the function
2516 oid_getoidbyent, which is not thread safe.
2518 * Added nmem_init and nmem_exit to initialize and release
2519 NMEM resources. Function nmem_init should be called once in the
2520 initial thread before NMEM/ODR is used. statserv.c and client.c
2521 have been changed accordingly. The change was necessary to make
2522 NMEM thread safe. The NMEM memory pool is shared amongst threads
2523 in a process. Unix-based applications will still work fine without
2526 Added NT Services interface for the the Z39.50 (statserv) Server.
2527 Refer to the ztest.c source on the usage.
2529 Windows 95/NT port using MSVC5.0. Project files are included in the
2532 * Defined new 'global' handle for the retrieval (data1) system. The
2533 new handled, data1_handle, describes the state of the data1 system.
2534 This handle is passed as first argument to virtually all
2535 data1 related routines. The functions data1_create and data1_destroy
2536 creates and destroys a data1 handle respectively.
2538 Added ODR encode stream member to all backend request structures
2539 init, search, scan etc. This stream should be used to allocate all
2540 memory used for the response when thread safe operation is needed.
2542 Changed the comstack utility, cs_addstr, to be thread safe. The
2543 returned hostname string returned by the function is now part the
2546 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2547 function. The cs_straddr takes a COMSTACK handle as argument, so this
2548 function must be used after cs_create and before bind/connect.
2549 This function is thread safe.
2551 Moved test server to 'ztest' directory - generic server code still
2552 in 'server' directory.
2554 Made prefix query (pquery.c) utility thread safe.
2556 Added new function modifier YAZ_EXPORT to 'export' public DLL
2557 functions when using windows (see include/yconfig.h).
2559 Added definitions to the OID database (util/oid.c) (RVDM).
2561 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2563 Added call to ccl_rpn_delete in client program.
2565 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2566 release of RPN structure.
2568 Added support for C++, headers uses extern "C" for public definitions.
2569 With input from RVDM.
2571 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2572 Thanks to Ronald van der Meer (RVDM).
2574 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2576 Added support for private extensions to the OID database
2577 (oid_setprivateoids()). Thanks to RVDM.
2579 Added optional, physical ANY (key replication)
2581 Fixed null-reference problem in GRS-1 output filter.
2583 Proximity operator added to Prefix Query Format (PQF).
2585 In test client command "base" accepts multiple databases.
2587 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2591 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2593 Smallish bug-fixes in the new encoders/decoders (explain).
2595 Bug fixed in DeleteRequest.
2597 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2599 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2601 Added SOIF syntax (using private OID for now) to retrieval module and client.
2603 Added Update extended service.
2605 Added SearchResult-1 additional info structure.
2607 Added optional CCL (ISO8777) interpreter as separate module. Available
2610 --- 1.2 1996/6/10 (1st anniversary release)
2612 Added Summary record syntax. Lightly tested.
2614 Added OPAC record syntax. Untested.
2616 Added ResourceReport service encoders/decoders. Untested.
2618 Fixed bug in z_Unit - wrong tagging on unitSystem.
2620 Fixed bug in the DiagRecs decoder.
2622 Added options for max PDU size and session timeout to frontend-server.
2624 Added documentation of query-language parsers and other supporting utilities.
2626 [frontend-server] Added Attribute set to the bend_scanrequest API.
2628 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2629 surrogate diagnostics were generated.
2631 [retrieval] Allow multiple local values for attribute.
2633 [retrieval] Allow multiple attributes per element in .abs files. index type.
2635 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2637 --- 1.1pl2 1996/4/10
2639 Minor changes, mostly specific to Zebra's requirements (retrieval)
2643 Repaired bug in frontend server when running multiple listening
2644 endpoints in dynamic mode.
2646 z_External() now won't break if a known, ASN.1 value comes encapsulated
2647 in an octet-string. The value will pass through unmodified in an Odr_oct.
2649 Added a bit of code to the demo client to decode & display
2650 ASN.1-structured records represented in the octet-aligned branch of
2651 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2653 Added z_ext_getentbyref() to the ASN module. Doc updated.
2655 * Completed the SCAN definition in the ASN module. This may break SCAN
2656 code based on older YAZ-versions at compile-time. The fix is easy -
2659 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2660 under the SCAN definition. Remember to initialize this, server-people.
2662 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2663 that this does not extend to ODR and ASN.
2665 Comstack allows insertion of established socket (primarily for
2666 inetd-operation of servers). Doc updated.
2668 Front-end server can now start from the inetd in TCP mode. Doc
2671 --- 1.0pl4 1996/1/24
2675 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2676 the rank and record number.
2678 Adjustments to the frontend server.
2680 Fixed diagnostic BER dumper. It ignored the file argument.
2684 Various changes to retrieval module.
2686 Changed the union discriminators of the protocol files from enums to
2687 ints paired with #defines.
2689 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2692 *Changed operator in the RPN structure to 'roperator', again to avoid a
2695 Fixed problems in Explain decoders/encoders.
2697 --- 1.0pl2 1995/12/6
2699 Memory bug in log module fixed.
2701 --- 1.0pl1 1995/12/5
2703 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2705 Bug in Explain DatabaseInfo module fixed.
2707 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2711 The shift to v1.0 signals that we now consider the *core* functionality
2712 of YAZ reasonably stable (the core being more or less equivalent to
2713 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2714 tested (Explain not at all - though that will happen soonish).
2716 Minor changes to code to support Windows port.
2718 Various minor changes after we're getting to use GRS-1 & co. more.
2720 Added Espec-1 format.
2722 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2723 of the protocol and it cannot be selected when encoding (maps into 'string'
2724 when decoding). Needed to talk to some servers.
2726 Demo client can request simple element set names.
2728 Added Diagnostic Format encoders/decoders.
2730 Added simple Close handling to frontend server (no hooks for resource
2731 reporting yet), and demonstration client.
2733 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2735 --- 1.0b3 1995/08/24
2737 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2738 handled incorrectly when records were requested in the searchResponse. This
2739 will only affect you if you use the frontend-server.
2741 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2742 Test-client will ask for and print GRS1. Ztest will return dummy records
2745 Added Explain encoders/decoders to the service-level API. Untested.
2747 Added Extended Services: Item Order encoders and decoders to the Service-
2748 level API. Untested. We could use a recent copy of the pertinent bits
2749 of the ILL protocol to add those bits.
2751 Added diagnostic format 1 encoders/decoders to the service-level API.
2754 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2755 odr_cons.c, which causes a more correct output.
2757 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2758 was always set to 0 when no records were requested in the searchRequest.
2760 * Added better external-handling. This shouldn't harm old code that
2761 *encodes* externals. It can break code that looks for a
2762 'single-ASN1-type' representation, since those types that are known
2763 are now decoded immediately. Look at the SUTRS sample code in
2764 seshigh.c and client.c. Documentation updated.
2766 Handling of structured records in bend_fetchresponse. Length -1 marks
2767 structured record, type is deduced from format field.
2769 --- 1.0b2 1995/06/27
2770 Fairly quick maintenance release to add SUTRS support.
2772 Fixed handling of SUTRS records in the demonstration client.
2774 * Added format field to the bend_fetchrequest and bend_fetchresponce
2775 structures of the backend API (frontend server). When the record is
2776 returned, the value of the format field is mapped to an OID. The
2777 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2778 of the record. The special value VAL_NONE in the bend_request means
2779 that no specific format was requested by the client. Documentation
2780 updated accordingly. Test server (ztest) will return a fixed dummy
2781 SUTRS record if your client requests SUTRS.
2783 Documentation updated accordingly.
2785 You can now set external libraries and RANLIB support in the top-level
2789 First public release.
