3 Forward decl timeval struct in mutex.h and gettimeofday.h.
5 yaz-config: fix 'static' mode linking.
9 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
10 are wrappers for pthreads or Windows. For Windows these are put in
11 a separate DLL: yaz_cond4.
13 libyaz.la (whole source) is compiled with thread. If thread support
14 is enabled enabled, all source of YAZ is compiled with treading support.
15 This allows core utilities such as yaz_log to use thread facilities.
16 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
17 thread utilities. This commit moves mutex utilities (mutex.c) from
18 libyaz_server.la to libyaz.la.
20 yaz-json-parse displays leading text until error.
24 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
25 patch from Giannis Kosmas.
27 SRU: no longer URL encode SRU database. The URL for an SRU server is
28 a URL and such is alreeady encoded - at least when given with leading
29 http:// or https://. This reverts behavior to YAZ 3.0.50.
31 Support for new MARC XML notation TurboMARC which like MARCXML is a
32 complete representation of MARC/ISO2709.. This one, however, is more
33 compact and allows for faster processing with XSLT. TurboMARC can be
34 used in the marcdisp.h API, from the yaz-marcdump utility and from
37 yaz-ztest can be configured - via the database - to perform certain
38 delays when it performs operations search, present and single record
39 fetch. This allows testers to make yaz-ztest act as a real or even slow
40 Z39.50 server. Refer to the yaz-ztest man pages for details.
44 wrbuf_destroy allows NULL WRBUF passed to it.
46 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
48 Add ZOOM_connection_close.
50 No fixed size buffers for ZOOM shell - bug #3257.
52 tstodr: make it work on s390 platform.
54 New icu iterator-functions. The new icu_iter-functions makes it possible
55 to use ICU chains from many threads.
57 yaz-client: better syntax check for show command.
61 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
64 New simple local-file XML include facility which allows file glob-patterns.
65 Refer to yaz/xml_include.h.
67 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
70 ZOOM_record_get supports new parameter "format" which makes it format XML
73 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
74 JSONText in ECMA-262) is JSONValue, not JSONObject.
78 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
79 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
81 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
82 POSIX/Unix builds .so with major version 4.
84 Remove old LOG_-defines from log.h. They have been obsolete and
85 undefined by default for the last 5 years.
87 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
89 GFS: Remove socket (int *fd) from search_rr handler. The socket
90 descriptor ptr is a facility that allowed a search handler to supply
91 a socket which would serve as a callback - when search was complete.
92 This facility has now been in use for years.
94 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
95 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
96 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
97 returns 'const char *' rather than 'char *. The returned string is
98 read-only and should not be modified by applications. COMSTACK cs_close is
99 now a void function - it no longer returns int. No applications check for
100 the value and the implementations has always returned 0.
102 ZOOM: use size_t for scan hit counts and str size. Functions
103 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
104 occ (hit count) and len (string length) are now of type size_t pointer
105 rather than int pointer. This is to be able to represent large hit counts
106 and to also just to use the proper type for string length (strlen result).
108 New JSON parser. Refer to include/yaz/json.h .
110 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
111 Used to be int in some cases. Many wrbuf_-functions used to return an int
112 indicating some length.. These return values were never used. And so they
115 ODR: odr_malloc, odr_total now takes size_t for size.
117 clone_z_type: fix leak; occurred for encoding failures.
119 --- 3.0.52 2009/12/03
121 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
122 bug was introduced in 3.0.51.
124 --- 3.0.51 2009/12/02
126 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
128 tcpip comstack: fix leak for getaddrinfo.
130 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
131 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
132 Decoding of SRU "path" database is performed by private function
133 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
134 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
136 yaz-client: honor base command for SRU. Change when database setting
137 is applied for SRU and ensure it is kept when a connection is reset.
138 Change also the way errors are displayed or SRU (decoding of packages).
140 --- 3.0.50 2009/11/02
142 Add support for extra request / response data for SRU codecs and GFS.
143 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
144 for extra data response buffer and length. For the GFS, both request
145 and response data (XML) is carried in extra_args and extra_response_data
146 for the search handler. Patch by Ko van der Sloot.
148 ZOOM: For queries that cannot be converted to the specified rpnCharset,
149 ZOOM now returns a diagnostic on the client-side ('invalid query' /
150 10010). This fixes bug #2113.
152 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
153 cmdfile included a 'quit' command that would result in a memory violation.
155 --- 3.0.49 2009/10/01
157 Make a number of functions defined in xmlquery.c static. These have
158 never been declared in a public header file (yaz/xmlquery.h) and was
159 made public by mistake.
161 Improve speed of character conversions (iconv utilities). This makes
162 conversions from MARC-8 faster.
164 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
165 unless type desired is "raw". This will prevent type "xml" from
166 returning ISO2709 .. Which obviously can not be XML parsed.
168 Fix memory leak in ZOOM that would occur if option apdulog was used
169 on a re-used connection.
171 Frontend server logs HTTP requests.
173 Frontend server now sends Z39.50 close when it times out (sesssion has
174 been idle for too long). Versions 2.0.30 and earlier also sent close.
175 But due to a mistake this was disabled in all versions after that, i.e.
176 the server would just close the socket immediately.
178 yaz-client emits a better message when receiving an unrecognised
179 userInformationField.
181 Skip zero-length subfields when decoding ISO2709. This rare case happens
182 if a record has two FS characters in a sequence. Without this patch
183 there would be a reference beyond char array in using_code_len fragments
186 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
188 --- 3.0.48 2009/08/28
190 The show command offered by the zoomsh command now takes a 3d optional
191 parameter type which is what is passed to ZOOM_record. If the type
192 argument is omitted, "render" is used.
194 RPN to CQL conv may use USE string attributes (bug #2978).
196 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
198 --- 3.0.47 2009/07/08
200 Function yaz_xml2query allows a diagnostic element in the PQF XML
201 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
202 code and additional info respectively.
204 The BER BOOLEAN is now the integral type Odr_bool which still happens
205 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
206 typedef'd to Odr_int. This is still an integral 'int', but it may be
207 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
208 ASN-1 compiler as well as programs has been updated to use the new types.
210 --- 3.0.46 2009/06/08
212 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
213 only the bibliographic record was rendered. For type=opac, an OPAC
214 record is only returned if it is present.
216 iconv: small fix for encoding of advancegreek.
218 yaz-client: avoid double display of SRU/SRW records (bug #2798).
220 yaz-client: option auto_reconnect=on really reconnects.
222 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
224 server: avoid null ptr ref for for yaz_poll errors.
226 build: fix RPM build for RHEL 5.3.
228 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
230 --- 3.0.45 2009/03/31
232 Fixed bug #2709: TCP connect returns Invalid argument.
234 Fixed compilation for mingw.
236 Honor charset for raw records (ZOOM_record_get).
238 Fixed use of errno for threaded mode that was seen on Solaris 10.
240 Fixed argument passing with blanks in value for Windows Service.
242 Disable YAZ' own log rotate by default (no 1 GB limit).
243 The variable l_max_size which specifies the log file limit is set to 0
244 (DISABLED): This is due to the fact that YAZ is most often deployed using
245 logrotate. Also YAZ can not perform log rotate because of unsufficient
246 permissions (setuid).
248 --- 3.0.44 2009/02/17
250 List supported encodings in man page for yaz-iconv.
252 Fixed missing SSL libs for --libs output
254 Re-established OID record syntax application-xml. Nobody should use it
255 but we don't want to change soname because of this symbol being absent.
257 --- 3.0.42 2009/02/02
259 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
261 Added member named_result_sets for init handler struct for the GFS. This
262 allows a server to disable named result sets.
264 Removed OID record syntax application-xml.
266 Added support for rule-based transliterator for ICU wrapper of YAZ.
268 Fixed bug #1902: yaz-icu XML output.
270 Make YAZ checks Emacs friendly.
272 BITSTRING value shows value. Bug #2346.
274 ISO2709 decoding: skip control characters from indicator data.
276 Omit sort key by default in yaz-icu's output.
278 Allow combined single char options (again) for YAZ' options function.
280 Utility yaz-marcdump got option to display YAZ version (-V).
282 Allow YAZ to use ICU 3.4.
284 Added new ICU test case which illustrates removal of diacritics.
286 --- 3.0.41 2008/12/29
288 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
290 --- 3.0.40 2008/12/29
292 For configure, using option --without-xml2 also disables Libxslt/Libexslt
295 Fixed bug #2352: yaz-marcdump crashes for certain record.
297 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
299 Added support for Danmarc2 to UTF-8 conversion.
301 Added support for ISO5426 to UTF-8 conversion.
303 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
304 implementation version.
306 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
308 --- 3.0.38 2008/11/10
310 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
311 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
313 ZOOM C now interprets databaseName option for ZOOM connection as path
316 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
318 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
320 Dummy Libxml2 types no longer defined in headers of YAZ'.
322 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
325 --- 3.0.36 2008/09/26
327 Various ODR chapter fixes.
329 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
331 Added missing source for Windows compilation, mutex.c.
333 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
335 For SRU connections in ZOOM all records up to "count" are now fetched.
337 Fixed crash in generic frontend server (and yaz-ztest) which occurred
338 in Windows due to bad error handling for Libxml2.
340 Added facility for sending arbitrary records (ASN.1 any) using
341 ZOOM C's Extended service update. Patch by Sam Reynolds.
343 New options for ZOOM C's connection, logapdu which makes ZOOM log
346 --- 3.0.34 2008/06/18
348 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
350 --- 3.0.32 2008/06/12
352 Fixed memory violation that could occur when decoding UTF-8. This bug
353 was only present in 3.0.30 of YAZ.
355 --- 3.0.30 2008/06/06
357 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
358 GNU TLS is used by default (if found).
360 yaz-ztest returns OPAC records if a client asks for OPAC.
362 Improved speed of MARC-8 encoding.
364 Added support for lossy and loss-less MARC-8 encoding.
366 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
368 Added new Windows Service wrapper (sc).
370 yaz-client's itemorder command may now send a file.
372 Fixed yaz-marcdump to allow the use of NS prefix for record element.
374 Added new function yaz_log_xml_errors.
376 Allow (but warn) unknown XML attributes in MARCXML parsing.
378 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
380 The UTF-8 to MARC-8 conversion now uses a different set of characters
381 for Greek symbols. Bug #2120.
383 --- 3.0.26 2008/02/21
385 Added yaz_daemon (daemon.h).
387 Fixed bug #2068: pkg-config trouble
389 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
391 --- 3.0.24 2008/01/28
393 Document --with-xml2 option.
395 Added OPAC XML XSD (etc/opacxml.xsd).
397 Allow glob mask for name attribute in retrieval element for the
398 generic frontend server's retrieval facility.
400 Changed yaz_poll_poll to return yaz_poll_except for all returned events
401 except POLLIN/POLLOUT.
403 Fixed error handling in cs_listen. Bug #2037.
405 --- 3.0.22 2008/01/20
407 Fixed version in yaz/yaz-version.h.
409 Fixed bug #2027: Crash when closing connection.
411 Changed configure so that ICU support is only enabled if only ICU
412 and Libxml2 is available (because the ICU chain is XML based).
414 --- 3.0.20 2008/01/15
416 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
417 is built. Only this DLL depends on the ICU runtime.
419 yaz-ziffy is no longer part of YAZ. It is distributed separately by
420 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
422 Changed license of CCL module to 'Revised BSD'. After consultation with
423 remaining members of the original EUROPAGATE consortium, we are re-issuing
424 the CCL module without a separate license. The software was developed by
425 Index Data as part of a research project. The special license was included
426 to help feed usage information back to the project consortium to support
427 project evaluation. At this time, the project consortium has long-since
428 disbanded, and the majority of the original principals have retired. At the
429 same time, we have significantly modified the software during the following
430 years, to the point where very practically no original code remains. To
431 simplify re-use of the software, we have contacted those members of the
432 consortium who could be reached, and agreed to re-issue the module as a
433 proper part of the YAZ package.
435 Tcl scripts uses /usr/bin/tclsh as preferred shell.
437 CQL closer to being version 1.2 compliant. CQL also allows free-form
438 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
441 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
442 bug could make Extended services handling crash in the ZOOM layer. This
443 bug was only present in YAZ 3.0.18.
445 --- 3.0.18 2007/12/19
447 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
450 yaz-marcdump reads and writes collection wrapped records.
452 Handle OPAC for record conversion module.
454 Fixes for ICU wrapper.
456 Allow ICU libs to be controlled with --with-icu .
458 --- 3.0.16 2007/11/12
460 Added yaz_poll which is a wrapper for select/poll. When poll is available
461 and non-buggy, it is used, by yaz_poll . This allows more than 1024
462 sockets to be in use.
464 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
465 functionality through an XML based configuration (ICU chain). This system
466 is useful for search facilities such as Pazpar2 and Zebra that needs to
467 perform tokenization of indexed material. The ICU code in a separate
468 library libyaz3_icu.a.
470 Added HTTP tunnel facility for COMSTACK, bug #1752.
471 This is a facility that allows a Web proxy, such as squid, to tunnel
472 Z39.50 traffic. This facility is "transparent" to must applications
473 using YAZ. It's enabled by using pseudo transport connect: followed by
474 the proxy address, followed by command, then follwed by he regular
475 "virtual" addresss. For example,
476 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
478 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
480 --- 3.0.14 2007/09/21
482 Fixed bad memory reference in ZOOM_record - cuased by member not being
483 initialized. This was a problem only in YAZ 3.0.12.
485 Fixed bug in conversion from MARC to XML: Non-XML characters in control
486 fields were not removed.
488 Changed the way C code is generated from codetables.xml. Made a MARC-8
489 conversion trie for each characterSet section rather than codeTable.
490 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
491 of codetables.xml from Larry Dixson, LOC. Bug #1464.
493 --- 3.0.12 2007/09/12
495 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
496 from ZOOM_record_error).
498 ZOOM C function ZOOM_record_get returns record schema for type="schema".
500 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
502 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
504 Better SRW-to-Bib-1 diagnostic mapping.
506 ZOOM C and yaz-client announces SRU version 1.2 by default.
508 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
511 Fixed in yaz_sru_decode to allow other version than 1.1.
513 --- 3.0.10 2007/08/22
515 Added support for SRU scan for ZOOM.
517 Added support for the use of the older versions or Extended Service
518 Update in ZOOM. To faciliate this, an option "updateVersion" may be
519 set to the version , 1=first, 2=second, 3=third. The third version is
520 what ZOOM C has used so far. And that, obviously, is the default.
522 Added support for CCL queries in Z39.50 queries sent to the GFS (and
523 therefore in Zebra and in SimpleServer-based applications). The new
524 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
525 qualifier file used to transform incoming CCL queries into Type-1 RPN,
526 which is passed into the back-end search callback function.
528 Added support for HTTP Basic authentication in clients: the SRU/W
529 codec encodes the username/password elements of the PDU structure
530 appropriately, and these may be set using the "user" and "password"
531 options in ZOOM-C applications (the same options that are used for
532 Z39.50 authentication).
536 Fixed bug #1208: SSL appears to be broken in ZOOM.
538 Fixed bug #1206: Libxml2 include path weirdness.
540 Added oid_name_to_dotstring.
542 Allow elementSetName to be specified for ZOOM C record update.
544 Allow waitAction to be specified for ZOOM C based for Extended Services.
546 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
547 syntax OID. Bug introduced in YAZ 3 series.
549 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
553 Fixed bug #1157: yaz-client does not read .yazclientrc from current
554 directory. yaz-client now reads commands from file given by option -f
555 if specified; then tries to read .yazclientrc in current directory.
556 Failing that, it reads .yazclientrc from user's home directory.
558 Added support for correlationInfo Note and ID for Record Update via
561 Added yaz-client command querycharset which specifies character set for
562 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
563 (termListAndStartPoint).
565 Charset ISO5428:1984 is an alias for ISO5428-1984.
567 Implemented a way to perform scan in a result set using Z39.50. This
568 is achieved by attaching the result set name in the characterInfo
569 (type InternationalString) of OtherInformation in the Scan Request PDU.
570 The result set is identified in the otherinformation by the new OID:
571 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
572 This allows for scan in result set and faceted search . Zebra did some
573 of this in the APT term using attribute type 8 and value being result
574 set. Using the OtherInformation approach for this is cleaner and easier
575 to work with in proxies and the like. This facility can be used in
576 yaz-client using new command setscan which takes a result set as first
577 argument, start position (APT) as second.
579 Changed decoding of SRU XML packed records to deal with servers that
580 have recordData with XML data with multiple root nodes. Also make
581 comparison for recordPacking case insensitive. Again, one server
582 returns "XML" where others return "xml".
584 For SRU responses allow Content-Type application/xml as well as text/xml.
588 Fixed bug in character set conversion of BER strings. Bug introduced
593 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
595 For OID class, use oid_class consistently.
597 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
600 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
601 character set for bibliographic information interchange". By Giannis Kosmas.
603 Added documentation on new OID API.
607 Changes to generic frontend server interface: added new member
608 'query_charset' for bend_initrequest structure. A backend init handler
609 should set this member to its native character set for query terms.
610 When defined, the frontend server logic will announce this character set
611 to a client if the negotiationModel bit is set by the client. All server
612 implementors are encouraged to specify this. If a backend server does not
613 specify this a warning is issued using yaz_log(YLOG_WARN,..).
615 Added CCL utility to remove terms (stop words) from resulting RPN
616 tree. This is handled by functions with prefix ccl_stop_words_ .
618 New ZOOM C option, "rpnCharset", which allows client-side conversion of
619 terms in RPN queries.
621 Clean-up the CCL API. Moved some internal structures from ccl.h to
622 private header cclp.h. Changed ccl_parser_create so that a Bibset must
623 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
624 This is replaced by ccl_parser_find_str which takes a string instead.
626 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
627 libyaz.la is the core of YAZ except the generic frontend server and
628 does not depend on POSIX threads anymore. libyaz_server.la is the
629 generic frontend server facilities and uses POSIX thread functionality
630 if available. The libyaz.la no longer depends on POSIX threads because
631 the number of global structures is limited. NMEM no longer re-uses blocks
632 between threads ; it simply free's memory immediately but allocates in
633 "large" chunks as usual. We don't expect any performance penalties
634 because of this. The yaz_log system is still using a global log_level so
635 caution must be taken when modifying it with yaz_log_init_.. +
636 yaz_log_mask_str. This, however, should not cause any trouble because
637 these functions are called during initialization of application code
638 anyway. `yaz-config --libs server` returns libs for server applications;
639 `yaz-config --libs` returns libs for non-server applications.
641 New OID database - with public definitions in oid_db.h. Removed old OID
642 database including the head oid.h and definitions such as enum oid_value
643 and struct oident. The new OID database uses the same string names as
644 before but the 'protocol' is gone. There are now only two representations
645 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
646 converts from string to OID; functions with prefix yaz_oid_to_string
647 converts the other way.
649 Change to emit_term() in CQL-to-PQF query translation: when a term has
650 the /regexp relation modifier, do not process it for leading and
651 trailing "^" and "*", which have quite different meanings in regular
654 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
655 write handlers no longer carries a 'last' parameter. This will make
656 yaz_iconv flush "less" characters. A flush is performed by call to
657 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
659 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
660 removed, because function yaz_query_to_wrbuf does the same.
662 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
663 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
665 Deprecated MARC utility functions removed.
667 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
670 Branch split: YAZ_2_1_55_branch
672 --- 2.1.54 2007/03/16
674 Fix to ZOOM-C so that transparent reconnection is properly handled on
675 connections that are in asynchronous mode.
677 Fixed compilation on OpenBSD 4.0.
679 Large strings in GRS-1 records are now properly displayed in yaz-client.
681 Added character conversion support for "advancegreek"; based on patch from
684 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
685 sequence is met. Before the error was not set so it would be unknown.
687 Adjust yaz-marcdump MARC reader so that it skips until record separator
690 --- 2.1.52 2007/03/07
692 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
693 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
694 fd_set structure used as a bitmask for the FDs to be selected on.
696 Using ACX_PTHREAD macro to check for POSIX threads.
698 Fixed have-vsnprintf check.
700 --- 2.1.50 2007/02/23
702 Fixes for configure on BSD. Bug #900.
704 Added snprintf/vsnprintf wrappers for systems that don't have
705 limits (heavens forbid).
707 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
708 created before all previous tasks were completed and removed from the
709 task queue, the new task could be removed by a mistake.
711 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
713 Implemented pass-through CQL-to-PQF conversions. Bug #861.
715 Fixed bug #832: Problem with MARC/charset in yaz-client.
717 Fixed bug #668: save command line history for yaz-client.
719 Fixed bug #830: pkg-config support.
721 --- 2.1.48 2007/01/23
723 Extended ZOOM result set options with two options that may be read by
724 a client: resultSetStatus and presentStatus with values as specified for
726 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
728 Fixed bug #827: Using SSL fails on Debian etch.
730 Fixed bug #826: Weird looking chars for set of MARC records.
732 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
733 that is treated as an ItemOrder with itemRequest being an XML document
734 external. The value of "doc" is the content.
736 Extended the GFS search facility. New member of bend_search_rr
737 'estimated_hit_count' signals that hits is known to be an estmate
738 (higher or lower than real hit count). New member 'partial_resultset'
739 signals that the search was partial (hit count is lower or equal than
740 real hit count). For Z39.50, the information is stored in resultSetStatus
741 member of SearchResponse APDU. For SRU, the information is signalled
742 via SRU diagnostic 59: "Result set created with valid partial results
745 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
747 --- 2.1.46 2007/01/13
749 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
751 Added ZOOM_connection_peek_event.
753 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
754 the following new functions:
755 ZOOM_event_nonblock, ZOOM_connection_process,
756 ZOOM_connection_get_{socket,mask,timeout},
757 ZOOM_connection_fire_event_{timeout,socket}.
758 The existing blocking event handler, ZOOM_event, is a wrapper for the
759 + blocking ZOOM_event_sys_{poll,select}.
761 Implemented function ccl_xml_config which parses XML version of CCL
762 configuration (bug #798).
764 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
766 Added timings utility (yaz/timing.h)
768 --- 2.1.44 2007/01/03
770 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
773 Fixed bug #779: Rotation of apdu.log fails.
775 Fixed for character set conversions:
776 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
777 Honor G1 set in MARC-8 decoding.
779 --- 2.1.42 2006/12/17
781 Fixed bug #775: char conversion does not handle Alternative UTF-8
784 Implemented function yaz_marc_read_line which parses MARC line format
785 records. There is a wealth of formats out there. So far, this function
786 reads line records produced by yaz_marc_write_line.
788 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
789 more generic and easier to remember(!) options: -i format and -o format
790 which specifies input format and output format respectively - where
791 format is one of "marc", "marcxml", "line", "marcxchange".
793 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
794 does not print anything except warnings for records.
796 For yaz-marcdump, added support for MARC split into files (-s) with a given
799 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
800 spec, at http://www.loc.gov/standards/sru/record-update/
801 This has changed the binary layout of the following structs:
802 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
803 bend_update_rr . Patch by Ko van der Sloot.
805 Added GFS utility function bend_assoc_is_alive which returns 1 if
806 association is still alive (client is connected); 0 otherwise (client
807 closed connection). This allows busy servers to stop working for
810 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
811 been a separate piece of software. This version of ziffy has been modified
812 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
814 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
816 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
817 Client code may now interrogate options such as "init_opt_sort" to
818 find out whether the server claims to support various options.
820 --- 2.1.40 2006/11/27
822 Added utilities yaz_{set,get}_esn to set/get element set name from
825 Removed the build of libyazthread.la. The libyaz.so is the threaded version
826 of YAZ and has been so since YAZ 2.1.10.
828 Implemented ZOOM_record_error which returns error information for
829 record (surrogate diagnostic).
831 --- 2.1.38 2006/10/31
833 Updates for SRU Update by Ko van der Sloot:
834 1. Changed name from "operation" to "action"
835 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
836 versions in the code, marked as 'backward compatible'.
837 3. Added diagnostics for SRU Update.
839 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
841 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
843 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
845 For GFS, fixed problem with SRU diagnostic 'First record position out of
846 range' being issued for 0 hits.
848 zoomtst10 part of Windows Build.
850 --- 2.1.36 2006/10/13
852 Implemented yaz_filepath_comp which splits a path into file path
853 components (required by Zebra 2.0.3+).
855 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
856 BSD inspired license until now so this should not have any real impact on
857 anybody. See http://www.opensource.org/licenses/bsd-license.php
859 Fixed bug #687: Missing log lines.
861 Fixed bug #678: CQL to PQF translation does not preserve double-quote
864 Fixed bug #689: SRU diagnostics to be added.
866 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
867 whether a connection is idle (no more work do do).
869 --- 2.1.34 2006/10/04
871 Change type of optval from long to int for invocation of setsockopt with
872 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
874 Added support for specifying the max log file size for the Generic
875 Frontend Server. The size is given with option -r.
877 --- 2.1.32 2006/09/21
879 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
881 --- 2.1.30 2006/09/17
883 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
886 Fixed bug in Generic Frontend Server that could cause a server to stop
887 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
889 For the generic frontend server, the maximum record size is used as maximum
890 size of incoming packages (SRU + Z39.50). The value until was previously
891 only used in Z39.50 Init negotiation and, later, in a session controlled
892 sizes of records returned. This is controlled using -k option. It can be
893 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
895 --- 2.1.28 2006/09/04
897 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
900 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
902 New option for yaz-marcdump -lpos=value which allows setting a portion
903 of MARC header to a certain value.
905 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
907 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
908 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
910 --- 2.1.26 2006/08/15
912 Fixed problem with SRU mode type (soap, get, post) for yaz-client
915 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
917 --- 2.1.24 2006/08/08
919 Fixed MARC ISO2709 encoding routines to deal with character set
922 Minor changes to GFS logging. Database included in search request log
925 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
926 cached/multiple records.
928 Shared libraries are built by default on Unix+configure.
930 Changed cql2pqf transformation to use a different evaluation order. The
931 new order is: always, relation, structure, position, truncation, index
932 and relationModifier. Old order was: always, relation, relationModifier,
933 structure, index, position, truncation. Note that the the latter ones
934 override former ones for identical attributes.. The new scheme means that
935 it is possible to override any existing attribute with a relationModifier.
936 And also that it is possible to override everything for the index rule
937 (except the ones listed in relationModifier). No order is perfect but this
938 one, we believe, covers more real cases.. The "always" should have been
939 called "default", since the attributes there can be overridden with all
942 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
943 compilation phase, but also for yaz-config --cflags output. This allows
944 us to have public headers with Libxml2 stuff in them . It should also,
945 eventually, make Libxml2 checks redundant in packages using YAZ, such
948 --- 2.1.22 2006/06/15
950 Changed SRU update structure bend_update_rr so that SRU diagnostics are
951 stored in uri, message and details.. Previously diagnostics were stored
952 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
953 compatibility.. but he's probably the only one affected, so.
955 Added support for CCL, compiled on the client side, in ZOOM-C. This
956 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
957 input; the resulting query objects can be used for for searching with
958 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
960 YAZ' configure searches for OpenSSL by default.
962 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
963 SL_CTX_use_certificate_file. See
964 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
965 for more info. Thanks to Ko van der Sloot.
967 --- 2.1.20 2006/06/02
969 Bug #600: SRU GET, POST support for yaz-client. Introduced
970 command 'sru' which selects method SOAP/GET/POST.
972 Allow missingValueAction to be specified for the sortspec string -
973 function yaz_sort_spec. By default, the missing value action is null.
974 Use ! to specify "abort". Use = followed by stringvalue to specify default
977 Ensured that Present-handler (if defined) is called in GFS before any call to
978 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
979 searchRetrieve requests.
981 Documentation for YAZ is now based on the Docbook XML/XSLT using
982 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
983 is no longer depending on jade/openjade or docbook-to-man scripts.
984 PDF is no longer part of the distribution - but can optionally be
985 made using DSSSL/jadetex or FOP.
987 Added retrieval handling support in Generic Frontend Server to support
988 conversion between MARC/XML as well as XSLTtransforms. See
989 etc/yazgfs.xml for an example.
991 Added Authentication support to Generic Frontend Server in SRU
992 mode. Authentication using HTTP Basic is supported, as is the use
993 of 'x-username' and 'x-password' parameters in the request itself.
995 Added support for a new character set MARC8s identical to MARC8 except
996 that it converts combined characters to single Unicode characters in the
997 Latin-1 range (when possible).
999 --- 2.1.18 2006/04/24
1001 ASN.1 compiler 0.4: generates brief Doxygen file header for
1002 generated .h/.c files.
1004 Utility yaz_iconv now supports conversion to MARC-8.
1006 New facilities for the MARC module. The reading - and writing of
1007 content are separate methods for the yaz_marc_t handle. The following
1008 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1009 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1010 format). Write functions have prefix yaz_marc_write_.. The existing
1011 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1012 available. Removed support for OAI-MARC and simplexml (not the
1013 simplexml from PHP5).
1015 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1016 to be returned for this connection.
1018 --- 2.1.16 2006/03/31
1020 Allow multiple languages and charsets to be specified with
1021 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1022 negcharset iso-8859-1,utf-8
1024 Translation of proximity nodes from CQL into PQF now works.
1026 Moved to automake 1.8, 1.9.
1028 Added function yaz_log_set_handler which allows a log handler to be
1029 installed. This handler will be called for all log messages. Output
1030 to file is also produced; but that can be disabled by passing NULL
1031 fname to yaz_log_init_file.
1033 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1035 For SRW (including GFS), accept application/soap+xml as content-type
1038 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1039 produces NO stylesheet reference even if a default stylesheet is specified
1042 --- 2.1.14 2006/03/14
1044 Updated Windows package to include yazd.dll + yazd.lib for the
1045 Development component.
1047 If the environment variable YAZ_LOG is set, then it is used as a
1048 string indicating the default level of logging to use if not
1049 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1050 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1051 used as before. So, for example, to omit warnings from YAZ logging,
1052 export YAZ_LOG=-warn
1054 cql_transform() now map structure and other attributes before indexes,
1055 so that index-specific structures and other attributes can override
1056 defaults. So now a combination of mapping specifications such as:
1058 index.dc.date = 1=date-modified 4=5
1059 does the right thing.
1061 cql_transform() now also respects the "always" mapping specification,
1062 which establishes an initial set of attributes to be used for all
1063 terms except where overridden by more specific attributes associated
1064 with the index, relation or modifier.
1066 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1067 which mode to use; one of "post", "get" or "soap" (SRW, default).
1069 Fixes for yaz_iconv routines: changed trie-based character set conversions
1070 to use only non-negative values for bit fields due to Sun's C compiler not
1071 supporting negative values.
1073 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1074 sequences where not read correctly. Fix by Rustam Usmanov.
1076 Updated win/makefile to use options, settings which makes things
1077 compile with VS C 2005.
1079 --- 2.1.12 2006/02/01
1081 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1083 In ZOOM socket code, use select instead of poll on MacOSX.
1085 ZOOM-C now support client-side compilation of CQL into RPN that is
1086 sent to the server, enabling CQL to be used against all Z39.50
1087 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1088 ZOOM_query object, and submit it using ZOOM_connection_search().
1089 The CQL-to-RPN translation uses a configuration file, the name of
1090 which must be specified in the Connection's "cqlfile" option.
1092 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1093 function, which takes as its start-term parameter a ZOOM_query object
1094 (which may have had either CQL or RPN set into it).
1097 --- 2.1.10 2005/11/29
1099 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1100 GFS to support this as well. Backend handler, bend_srw_update, does the
1101 update work. Code contributed by Ko van der Sloot.
1103 Allow retrieval of Search Result-1 information in ZOOM by the use of
1104 options that are attached to a result set. ZOOM documentation updated
1107 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1108 UTF-8 conversion. Patch by Raj Patel.
1110 Added option -m to GFS to control formatting of timestamps in log file.
1112 Added 'exit' as synonym for 'quit' in yaz-client
1114 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1115 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1116 for the new members. Patch by Ko van der Sloot.
1118 Added support for SRU POST. It is supported for content-type
1119 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1121 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1122 Instead make the library libyaz.la multi-threaded. Threading as a whole
1123 can still be disabled by configure option --disable-threads. Previosly,
1124 with older GLIBCs there were problems with MT libs under Apache. This
1125 has now been fixed a long time ago.
1127 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1130 CQL module modified to be case insensitive for relations/indexes/operations.
1132 Fixed bug in CQL transform code: incorrect value relationModifieder
1135 Added 'show all' command for yaz-client which retrieves all results
1138 Added new yaz-client, xmles, which takes a (private) OID and
1139 a document to be sent as an extended service request.
1141 Describe new yaz-client commands wait_response and set_auto_wait.
1143 Increase TCP/IP listener backlog from 3 (which I am guessing was
1144 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1145 that the socket will queue as many incoming connections as it's able
1146 to handle ongoing connections. In other words, it will never now
1147 refuse a connection that it would be able to handle merely because
1148 it's not got around to accepting() enough of the pending connections
1149 yet. This is the behaviour anyway under Linux, where the listen()
1150 argument is ignored; but not under BSD and on systems such as
1151 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1152 YAZ-based servers should now be uniform across operating systems in
1155 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1156 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1157 This allows yaz-marcdump to read large MARC batches (>2 GB).
1159 Modified all YAZ source files - except the source which is auto-generated
1160 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1163 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1164 corresponding to the existing *_setl() function. These allow option
1165 values containing arbitrary valuues.
1167 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1168 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1169 except that it returns an indicator of whether or not the sort
1170 criterion was accepted (0 for OK, -1 for invalid).
1172 --- 2.1.8 2005/06/07
1174 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1175 MARC output rather than returning "new" buffer.
1177 yaz-client warns about unknown init options.
1179 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1181 --- 2.1.6 2005/05/24
1183 Added support for SRW sort in Generic Frontend Server. Patch
1184 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1185 sortKeys - or NULL if none is provided.
1187 Fixed bug #307: It was impossible to specify indefinite/no timeout
1188 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1191 Added support for multiple languages and charsets to be specified in
1192 ZOOM. Each charset/language is separated by a blank. If negotiation is
1193 in effect in init-response, Option
1194 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1195 Code based on patch by Vasiliy Osadchuk.
1197 Fixed bug #306: infinite recursion that occurred when calling
1198 yaz_log_level_init as the first call (before other log level or
1201 Fixed bug in scan handling in front end server: if preferred-Position-In-
1202 Response was non-present, a NULL pointer referece was performed.
1204 --- 2.1.4 2005/04/26
1206 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1207 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1208 now defined for all those error codes. So instead of putting 109 in
1209 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1210 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1212 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1215 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1217 Program yaz-client now exits and produces an error message if multiple
1218 Z39.50 servers are specified on the command line (none or one allowed
1221 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1224 --- 2.1.2 2005/03/16
1226 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1228 Fixed bug #272: Preserve spacing for CCL terms.
1230 --- 2.1.0 2005/03/14
1232 Added support for virtual hosts and multiple backend servers for
1233 the YAZ frontend server. The configution is XML based and
1234 support specificition of CQL to RPN mappings and explain information.
1235 See section "Virtual Hosts" in the YAZ manual.
1237 Extended OPAC display utility. OPAC display utility renders
1238 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1239 to supplement yaz_marc_decode_wrbuf.
1241 Fixed a bug in MARC decoder that could caused it to crash for some
1242 invalid MARC records. More diagnostics and warnings where added in
1243 XML output (warnings, etc are stored in comments).
1245 --- 2.0.34 2005/02/08
1247 Fixes for UNIX domain sockets. Bug #261.
1249 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1251 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1252 Added yaz_marc_subfield_str which defines subfield lead string which is
1253 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1254 yaz_marc_endline_str which defines end of fields string used in
1255 YAZ_MARC_LINE format. Default string is newline.
1257 Experimental support for MarcXChange. This format can be produced
1258 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1259 http://www.bs.dk/standards/MarcXchange.xsd
1261 Added yaz-client commands scansize that sets maximum number of
1262 entries to be returned by scan.
1264 --- 2.0.32 2005/01/11
1266 Added support for SRW scan in yaz-client and Generic Frontend Server.
1268 * Added whereInList member to SRW Scan Term.
1270 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1272 Fixed NMEM system to return aligned blocks on the smallest boundaries
1273 that are suitably aligned for all possible types on the particular
1274 architecture YAZ is being built for.
1276 --- 2.0.30 2005/01/04
1278 Fixed numerious warnings that was issued with newer versions of GCC.
1280 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1281 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1284 Make YAZ Generic Frontend Server slightly faster.
1286 Enhance (and reduce) logging for Generic Frontend Server.
1288 Revert YAZ log system so that it flushes every write operation
1289 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1291 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1292 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1293 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1294 will effectively disable old definitions.
1296 --- 2.0.28 2004/11/09
1298 Added yaz_log_time_format which specifies log format using
1301 Added yaz_log_module_level which returns mask for a module. Value
1302 is non-zero mask a if module is enabled; zero if disabled.
1304 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1305 in include/yaz/cql.h.
1307 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1309 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1311 Fixed bug #172: RPM builds does not enable SSL.
1313 Doxyfile.in part of dist. Doxyfile generated by configure.
1315 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1316 are given and the corresponding component does not exist.
1318 Extend CCL documentation in YAZ reference. Describe r=r.
1320 --- 2.0.26 2004/10/01
1322 Fixed MARC->MARCXML conversion to properly deal with
1323 fields, subfields, indicators having non-ASCII characters.
1325 Fixed MARC->MARCXML conversion so that ASCII control characters
1326 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1329 Added YAZ GFS support for conversion from Z39.50 surrogate
1330 diagnostics to SRW surrogate diagnostics.
1332 Bug fix: YAZ GFS did not return schema in explainResponse.
1334 --- 2.0.25 2004/09/30
1336 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1337 now converts recordSchema to elementSetName as well as schema URI.
1339 Fixed bug in COMSTACK that prevented HTTP request packages from being
1342 --- 2.0.24 2004/09/29
1344 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1345 does not require white-space before and after the dash in a range, e.g.
1346 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1349 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1350 due to new GCC removing "redundant" code.
1352 Added yaz-client commands scanpos and scanstep that sets preferred
1353 position and step-size for scan.
1355 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1357 Added CCL utility ccl_qual_buf which parses one or more CCL
1358 spec lines in a buffer.
1360 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1361 of name and value - ignoring empty lines and comments.
1363 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1365 Added odr_get_element_path which returns current element path for an
1366 ODR handle. This utility is useful in error handling or user-defined
1369 Added ODR_PRINT utility odr_set_stream which is is a more generic
1370 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1371 to a write function and pointer to close function. The close function - if
1372 non-NULL - will be called during odr_destroy.
1374 Fixed bug in CCL parser where truncation char was not removed from
1375 right side when truncation=both was in effect.
1377 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1380 --- 2.0.23 2004/08/11
1382 Fix buffer overrun in CQL parser when dealing with proximity (%).
1384 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1385 to UTF-8/UCS conversion is now only based on codetables.xml.
1387 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1389 --- 2.0.22 2004/08/06
1391 Add support for more "commit changes" in ZOOM (uses Extended Services).
1393 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1396 Yet another small fix for configure of SSL.
1398 --- 2.0.21 2004/05/14
1400 Fix SSL libs for configure when --with-openssl=DIR is given.
1402 --- 2.0.20 2004/05/10
1404 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1406 SSL comstack now uses yaz.pem certificate file on server side
1407 by default. Certificate filename can be configured by calling
1408 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1410 Fix bug regarding multiple calls to ZOOM_connection_connect.
1412 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1414 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1415 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1417 ZOOM now allows inspection of X509 peer certificate for verification.
1418 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1420 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1421 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1422 as "modular" but it simplifies things.
1424 Added cs_get_peer_certificate to that returns peer X509 PEM.
1426 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1427 NULL if SSL is unavailable.
1429 Documentation about MARC decoding tools.
1431 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1433 --- 2.0.19 2004/03/30
1435 Rename CHANGELOG to NEWS to follow GNU style packing.
1437 Fix bug with missing initialization of member in init_diagnostics.
1438 This bug affects threaded version of GFS server.
1440 --- 2.0.18 2004/03/20
1442 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1445 Ensure zlib.dll is packed with Windows install.
1447 --- 2.0.17 2004/03/17
1449 Fix encoding of xsd:string to use text instead of CDATA.
1451 Fix endless loop in CQL parser with unbalanced ".
1453 Use a more compact way to store MARC-8 conversion tables.
1455 --- 2.0.16 2004/03/16 Debian only
1457 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1460 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1465 --- 2.0.15 2004/03/01
1467 Another fix for decoding of XML packed records.
1469 --- 2.0.14 2004/02/25
1471 Fixes for Chunked encoding. White space not ignored after length spec.
1473 Update NS and use default NS for SRW diagnostic elements.
1475 --- 2.0.13 2004/02/23
1477 Implement ZOOM_resultset_cache_reset which resets record cache.
1479 Implement ZOOM_resultset_sort which sorts a result set.
1481 Implement chunked HTTP transfer.
1483 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1485 --- 2.0.12 2004/02/16
1487 Added member 'schema' to bend_explain_rr structure so that backend
1488 can specify explain record identifier. Defaults to Zeerex 2.0.
1490 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1492 --- 2.0.11 2004/02/16
1494 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1497 Added init command for yaz-client which sends "extra" init request.
1499 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1500 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1502 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1504 Make ZOOM error code for "invalid query".
1506 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1508 --- 2.0.10 2004/02/05
1510 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1513 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1515 Added option -p <file> to make Generic Frontend Server to write PID file.
1517 Added option -D to put Generic Frontend Server in background on its own.
1519 Make ZOOM C recognize option "password". If unset, "pass" is used
1520 (for backwards compatibility).
1522 Fixed a bug in Generic Frontend Server that could make it crash if a
1523 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1526 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1527 Must be issued before open, in order to be in effect.
1529 --- 2.0.9-6 2004/01/12 Debian/Windows
1531 Make the SRU server more picky WRT unknown params, etc.
1533 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1535 New YAZ client command, options, that sets Z39.50 options.
1537 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1538 options from a string of tokens (one token for each option bit).
1540 Update SRW diagnostic code messages.
1542 --- 2.0.9-5 2004/01/07 Debian/Windows
1544 Handle user defined stylesheet for SRW/SRU.
1546 --- 2.0.9-4 2004/01/06 Debian/Windows
1548 Fix bug in decoding of Content-Length.
1550 --- 2.0.9-3 2004/01/06 Debian/Windows
1552 Fix a bug with decoding of XML packed records.
1554 --- 2.0.9-2 2004/01/05 Debian only
1556 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1558 Fix bug in SRW/SRU diagnostics decoding.
1560 --- 2.0.9 2004/01/05
1562 Fixed bug in Generic Frontend Server which could drop records exceeding
1563 preferred message size. Reported and fixed by Irina Dijour.
1565 Fixed calculation of package size for structured records in Generic
1566 Frontend Server. Reported and fixed by Irina Dijour.
1568 Fixed namespace for SRW/SRU diagnostics.
1570 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1572 --- 2.0.8 2003/12/22
1574 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1575 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1578 CQL changes to reflect recent changes to the specification:
1579 * Documentation talks about context sets instead of index sets.
1580 * Documentation talks about indexes instead of qualifiers.
1581 * The CQL-to-PQF transformer's configuration file now uses
1582 "index.set.name = <attributes>" instead of the old form
1583 "qualifier.set.name = <attributes>". (Both forms are still
1584 understood but the latter is deprecated.)
1585 * CQL terms with no explicit index specified are now interpreted as
1586 cql.serverChoice instead of srw.serverChoice (which of course
1587 behaves exactly the same.)
1589 --- 2.0.7 2003/12/16
1591 MARC conversion can now generate ISO2709 output in another
1592 character set. yaz-marcdump uses this facility if you invoke it
1595 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1596 functions from there can be used from C++.
1598 --- 2.0.6 2003/12/04
1600 Frontend server now transfers memory from decoded packages to stream
1603 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1604 references to show up.
1606 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1607 the ZOOM Abstract API. The older names for the same options are still
1608 also supported for the benefit of old applications.
1610 ZOOM-C supports "implementationId" and "implementationVersion" options
1611 to go along with "implementationName". These allow the user code to
1612 specify identification strings to be sent to servers.
1613 Add OID for the new ExtLite attribute set.
1615 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1616 as requested/supplid by Ere Maijala <ere@atp.fi>
1618 For generic frontend server, reverse the order of
1619 "toolkit-supplied / application-supplied" strings sent as implementationId,
1620 Name and Version. Also, remove the spaces around the slash. This brings
1621 the GFS in line with the behaviour of ZOOM-C on the client side.
1623 Add function ZOOM_scanset_display_term.
1625 yaz-client shows scan displayTerm if present.
1627 Utility yaz-iconv is now installed by default along with the man page
1630 Extend configure check for OpenSSL to use pkg-config where available (such
1633 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1634 server to specify uid/gid/mask for socket using the format
1635 unix:[user=uid,][group=gid,][umask=mask,]file=path
1636 If file= is omitted the existing format is assumed, e.g.
1638 in which case the mask is 0666 (rw for everybody).
1640 Major restructure of YAZ source. All source in libyaz is in src directory.
1641 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1642 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1644 Added man page for utility yaz-marcdump (used to be called marcdump).
1645 yaz-marcdump is installed by 'make install'.
1647 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1648 of incoming package failed.
1650 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1652 Change prototype of odr_perror: add const to message string.
1654 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1656 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1657 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1658 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1659 DNS lookup. There should not be any compatibility problems with this
1660 assuming that blocking=1 or 0 is used.
1662 Fix bad reference in UNIX comstack in function cs_addrstr.
1664 Fix for compilation on AIX.
1666 The generic front-end server (server/seshigh.c) now supports returning
1667 Init diagnostics to the client in User-information-field, in
1668 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1671 --- 2.0.4 2003/09/04
1673 Allow any CQL relation (not just all,any,exact,scr).
1675 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1676 that features the same UI.
1678 Implemented command update0 in YAZ client which is equivalent to
1679 update but uses old of Ext Update ASN.1.
1681 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1682 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1683 Previously no OID was used for this info.
1685 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1686 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1687 returns 'malformed search term' otherwise.
1689 SortResponse member resultCount now set to NULL in sort handler of
1692 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1695 Add three new utility functions for translating OIDs between various
1696 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1697 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1698 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1699 char *oid_to_dotstring(const int *oid, char *oidbuf);
1700 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1702 Reverted modifications for ES Update definition for z_IU0Update
1703 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1704 is back to YAZ 2.0.2.
1706 String value attributes for CCL parser.
1708 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1709 which their FirstSearch server returns in Init responses, sometimes
1710 carrying useful diagnostic information when Init fails. This has the
1711 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1712 "z39.50/oclcui.asn", where its definition is somewhat different from
1713 what OCLC document on their web-site, as required to interoperate with
1716 Support for anonymous authentication in yaz-client. Use the command
1719 * Fix the OID of the Index Data-local "admin" Extended Service from
1720 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1721 the 1000, which indicates a locally-defined OID, was a mistake.
1723 --- 2.0.3 2003/06/20
1725 Fix CCL directive @case handling so that it affects string match for
1726 both CCL keywords and qualifiers.
1728 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1729 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1730 Decoder has been updated with ASN.1 changes as listed in
1731 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1732 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1733 z_IUUpdate, remains unchanged.
1735 ZOOM_record_get may now return a record in a specific character set.
1736 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1737 "from" is the character set of record as returned by target. "to" is
1738 the character set to be returned. If omitted, "to" is UTF-8.
1740 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1742 New ODR utility, odr_getelement, which returns name of element for
1743 which encoding/decoding failed.
1745 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1746 in cases where a required element was omitted.
1748 Bug fix: some MARC8 sequences were not converted.
1750 New ZOOM option "step" which specifies number of records to be
1751 retrieved in one chunk. Used in conjunction with "start" and "count".
1753 SRW support for yaz-client. Use scheme http: to use it, e.g.
1756 yaz-client no longer does (un)intelligent character set conversions
1757 by default. Can be enabled with charset and marc_charset commands.
1759 xmalloc trace fix for 64-bit systems such as DEC alpha.
1761 Solaris 2.6 compile fix.
1763 New function, cql_strerror() translates SRW error codes, as returned
1764 by cql_transform_error(), into human-readable English strings. Used
1765 in yaz-client diagnostics when appropriate.
1767 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1768 converts it into a type-1 query which is sent to the server. This
1769 makes CQL available for use with all Z-servers, as opposed to the tiny
1770 minority that can handle CQL queries themselves.
1772 --- 2.0.2 2003/04/28
1774 New Debian package layout similar to the Redhat Package layout.
1776 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1777 and search result respectively.
1779 --- 2.0.1 2003/04/25
1781 Redhat package is now several packages: libyaz (runtime libraries),
1782 libyaz-devel (development and documentation, and yaz (utility programs).
1783 Package spec file by Morten Bogeskov.
1785 New member 'schema' in struct bend_fetch_rr which the name of requested
1786 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1787 handler MAY set this to reflect the schema of the returned record.
1789 New member 'display_term' in struct scan_entry. GFS now sets member entries
1790 and allocates scan entries to be filled by user scan handler. In previous
1791 version, entries member was allocated by the scan handler. That still works,
1792 but the GFS will ignore member display_term - assuming it was NOT set by
1793 the handler. The fact that the GFS now allocates the entries both allows
1794 for new members and makes a scan handler easier to write.
1796 Fix CQL lex buffer overflow.
1798 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1799 SRU default recordPacking is string.
1801 SRU protocol support for frontend server.
1803 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1805 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1807 Added scan for the ZOOM shell (zoomsh).
1811 * String Identifers for Schemas (Amendment 5).
1812 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1813 Old definition for schema
1814 Odr_oid *schema; /* OPT */
1819 Z_InternationalString *uri;
1820 #define Z_Schema_oid 1
1821 #define Z_Schema_uri 2
1824 * resultCount parameter to Sort Response (Amendment 1).
1825 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1827 Support for SRW 1.0 over HTTP. This is an optional feature and
1828 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1831 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1832 on the same port. SRW SearchRetrieveRequests are mapped
1833 to bend_init,bend_search,bend_fetch,bend_close.
1835 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1837 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1838 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1840 ZOOM connections are SRW based if schem http is used for hostname
1841 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1842 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1844 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1845 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1846 distance=n, order=true/false, relation=le, prox unit=word. If
1847 n is omitted, distance 1 is used.
1849 Fixed problem with C compiler include path in wrong order.
1851 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1852 on Solaris. Patch from Ko van der Sloot.
1854 New MARC decode API. All new functions operate on a yaz_marc_t
1855 handle. The most important new functions are: yaz_marc_create,
1856 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1857 decode and destroy respectively. Decoder can produce formats
1858 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1859 include/yaz/marcdisp.h.
1861 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1862 to UTF-8, UCS-32, wchar_t or Latin-1.
1864 * Prototypes for yaz_iconv_-functions moved to separate header
1865 include/yaz/yaz-iconv.h.
1867 Make a few private functions 'static' in unix.c. This prevents
1868 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1870 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1871 are set when Init Response is received.
1873 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1874 but returns diagnostic set as well.
1876 New function yaz_strerror which is a portable wrapper for
1877 strerror/strerror_r/GetLastMessage.
1879 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1880 is returned for MARC. If type is "oai", then OAI MARC is returned.
1882 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1885 --- 1.9.2 2002/11/26
1887 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1889 Fix bad race conditions on SIGTERM and terminate gracefully in
1892 Move retrieval (data1) module to Zebra since nobody seems to be
1895 Add GRS-1 render for ZOOM using same format as yaz-client.
1897 --- 1.9.1 2002/10/05
1899 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1901 Fix broken ESpec handling in data1 module.
1903 SGML reader parses comments and makes them part of the data1 tree.
1905 Added several type casts so that YAZ compiles as C++ code.
1907 ZOOM didn't handle PDU encoding failures properly.
1909 Added more Bib-1 diagnostics (approved extensions).
1911 GNU configure: better check for iconv.
1913 More portable use of accept, getpeername. Check for socklen_t. Use
1914 int/size_t if socklen_t is not defined.
1918 PQF parser rejects bad queries - including those with extra
1919 characters in them. PQF parser used to silently ignore that.
1920 Cleaner API for PQF added, which allows you to get detailed
1921 error information for bad queries (see yaz/pquery.h).
1923 Fixed bug in ZOOM_record_get for type "database".
1925 Implemented mini iconv library supporting conversions between
1926 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1928 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1930 --- 1.8.9 2002/08/20
1932 Fixed ZOOM C record cache so that preferredRecordSyntax and
1933 elementSetName is used to check for already fetched records.
1935 --- 1.8.8 2002/08/02
1937 Added three members in bend_initrequest structure to facilitate
1938 character set negotiation.
1940 Fixed a bug in frontend server that could cause indefinite
1941 loops under rare conditions.
1943 Revised character set utilities (charneg.h) so that encoding
1944 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1946 For PQF, directive @term <type> sets term type for Scan/Search.
1947 Here <type> is general, string, numeric, null. The term type
1948 is inherited - just like @attr.
1950 New call odr_set_charset that sets character set conversion for
1951 international-strings on a ODR stream. Prototype is:
1952 int odr_set_charset(ODR o, const char *to, const char *from);
1953 The InternationalString is still represented as C string in YAZ
1954 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1955 won't). On the protocol level, you can use any encoding.
1957 Support for UNIX sockets in ZOOM.
1959 Solaris recv sometimes returns errno == ENOENT. It is treated as
1960 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1962 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1963 both client and server. Code by Morten Bogeskov.
1965 --- 1.8.7 2002/05/22
1967 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1968 that they can be used directly from Visual Basic. You must recompile
1969 your windows APP if you're using ZOOM.
1971 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1972 Commands "lang" and "charset" sets language and character set respectively.
1973 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1974 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1976 Attributes from multiple CCL fields may be OR'ed rather than merged
1977 using directive "@field or". Fields are still merged by default -
1978 equivalent to "@field merge".
1980 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1983 Fixed bug in zget for parameter ExtendedServicesResponse.
1987 --- 1.8.6 2002/03/25
1989 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1991 Client displays USR.1:SearchResult-1 (hits per term).
1993 Additional Search Info for search in Generic Frontend Server.
1995 Fixed CCL parsing of "field=s".
1997 WIN32 installer - using the excellent NSIS software from nullsoft.
1999 Fixed CCL parsing of "field = - <number>".
2001 Added function yaz_marc_decode that decodes MARC for line mode
2002 display or XML (similar to that used by JZKit).
2004 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2005 Z39.50. But ISO/ILL was, however.
2007 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2008 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2010 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2011 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2013 --- 1.8.5 2002/02/03
2015 New YAZ client features: Command completion and new commands:
2016 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2017 Code provided by Jacob Poulsen.
2019 New call oid_trav, that visits all registered OIDs via callback.
2021 Function ZOOM_record_get now returns const char pointer rather than
2022 void pointer. It saves a lot of type casts.
2024 For YAZ client, command "auth" now allows you to set authentication
2025 in IdPass style. It is enabled when three tokens are given - order
2026 is user, group and password.
2028 Fix memory leaks in MARC record handling for ZOOM.
2030 New option for YAZ client, -k <kilobytes> that sets
2031 maximum record size. Similar to -k option for generic frontend
2032 server and yaz-ztest.
2034 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2036 Prefix query parser reports "fail" when bad attribute set is given.
2038 Fix in MARC decoder. Proximity logging. Fix for attribute set
2039 in scan handler for server. Patches by Shigeru Ishida.
2041 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2044 Configure option --with-openssl=<dir> now works when a directory is
2045 specified. Patch provided by Morten Bogeskov.
2047 New option for YAZ client, -u <auth>, that sets authentication.
2049 ZOOM fix: error information was sometimes "missing", since error
2050 was cleared/reset too when it shouldn't.
2052 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2054 --- 1.8.4 2002/01/04
2056 Scan for ZOOM API. New object ZOOM_scanset. New functions
2057 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2058 ZOOM_scanset_destroy.
2060 New ZOOM function, ZOOM_connection_last_event, that returns type
2061 of last event (such as "receive data", "send data", "apdu received",
2064 New ZOOM option, schema, that specifies schema for retrieval.
2066 New CCL feature. Qualifiers can be aliases for one or more
2067 other qualifiers (if more than one is given, OR is used).
2069 ZOOM uses named result sets if target supports it.
2071 Two new YAZ client commands: . (dot, which sources a script of YAZ
2072 client commands), and ! (to execute shell command.). Implemented
2075 Working on Debian packages.
2077 --- 1.8.3 2001/11/19
2079 YAZ client enables named result sets only if target supports it.
2081 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2083 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2084 with key="host" to get same result.
2086 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2087 Function Z3950_resultset_record(s) returns references to records
2088 "owned" by resultset. To become owner use Z3950_record_clone.
2090 Function z_ext_record handles Extended Services. Thanks to
2093 --- 1.8.2 2001/11/12
2095 CCL Parser fix: ignore token comma when dealing with and-lists.
2097 Documentation updates for COMSTACK.
2099 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2100 Changed prototype Z3950_records. For some functions, int parameters
2101 were changed to size_t.
2103 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2106 New MARC decode/display function, marc_display_exl, which properly rejects
2107 non-ISO2709 records. YAZ client uses it.
2109 --- 1.8.1 2001/10/29
2111 Fix bug: local attribute set wasn't set correctly in PQF strings.
2115 * Old Z39.50 codecs no longer supported.
2117 Added ZOOM C binding. See http://zoom.z3950.org/
2119 Renamed states for COMSTACKs to avoid confusion with events.
2121 Implemented cs_look and proper cs_rcvconnect.
2123 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2125 Configure detects POSIX threads on OpenBSD.
2127 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2128 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2130 When error is returned from present handler, non-surrogate diagnostic
2131 is returned in present response (and fetch handler is no longer called).
2133 * Minor adjustments to pquery parser (PQF). Token characters may be
2134 escaped by using backslash (C-style).
2136 PQF parser allows string attribute values to be specified. For @attr,
2137 non-numeric characters after the equal-sign are treated as strings
2138 (e.g. @attr 9=title).
2140 CCL trunction character may be defined (@truncation in file)
2142 * function zget_ExtendedServicesRequest sets waitAction to
2143 waitIfPossible (was wait).
2145 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2148 CCL operator names may be set in field definition files (CCL_bibset).
2149 See ccl/bib1 for an example.
2151 Fixes in ASN.1 compiler for C++ compatibility.
2153 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2154 and "op_or" to avoid conflict with C++.
2156 Fixed problem with GNU readline detection on Redhat 7.0.
2158 Added step-size for Scan backend handler.
2160 Fixed bug that made the frontend server crash when no attribute
2161 set was specified for scan.
2163 Front-end server automatically switches to original working directory
2164 when installed as an NT service. Previously -w had to be specified to
2167 Added extended attributes for retrieval module (data1), so that data1
2168 records carry d1_readXML/SGML attributes. d1_read also supports
2169 null-data rules ( <tag/>)
2171 On UNIX when POSIX threads are available, a separate library libyazthread
2172 is created. Programmers should link with that library and the yaz library
2173 when using threads. The reason for the split was that some applications
2174 on Linux, such as Apache, doesn't work well when using shared objects that
2177 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2178 (or any frontend server) in SSL mode by specifying ssl: followed by
2179 address. Only tested on UNIX.
2181 Added feature for CCL module. Virtual structure s=al or s=ol generates
2182 and-list and or-list respectively instead of phrase search.
2186 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2187 log_mask_str. This was done to avoid name conflicts with other libraries
2188 (such as other PHP extensions).
2190 Added raw OID member for preferred record syntax (request_format_raw)
2191 and returned record syntax (output_format_raw) for backend fetch method.
2193 Config file yaz-config now accepts options so that it returns specific
2194 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2196 Shared library support for UNIX using GNU libtool.
2198 * Modified backend interface. Request/Response struct's replaced by
2199 one read/write C struct. For example bend_fetchrequest and
2200 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2201 Every handler - even search has to be registered in bend_init
2202 handler. This means that the YAZ library no longer refers to
2203 external functions and it makes it possible to make the whole
2204 thing a single DLL/SO.
2206 Added Segment handler for backend server.
2208 Added Zmbol/Zebra administrative functions to YAZ client.
2210 Threaded frontend server on UNIX (when POSIX Threads are available).
2211 Starting the server with option -T enables multi-threading.
2215 Added configure option --enable-comp/disable-comp to control use
2216 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2217 located in sub directory asn.
2219 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2220 in ${exec_prefix}/bin along with the other programs yaz-client and
2223 GNU automake used to maintain makefiles.
2225 Added several OID's.
2227 Changed retrieval module so that we can load records with no abstract
2228 syntax defined. Tagpaths in these records are fully composed of string
2231 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2235 On UNIX, the generated makefile now supports a proper 'make install'.
2236 The prefix can be set via GNU configure to set the install location
2237 (default is /usr/local).
2239 * YAZ programs client and ztest were renamed to yaz-client and
2240 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2241 locations, such as /usr/bin,/usr/local/bin,etc.
2243 * YAZ Header files were moved from include to include/yaz. YAZ Header
2244 files are referred to as include <yaz/log.h> rather than <log.h>.
2245 The YAZ include path (-I ..) is therefore the same as before. Programmers
2246 should update their #include statements or use -Ipath/include/yaz
2247 instead. The main motivation for doing this change is that YAZ header files
2248 can be installed in "standard" locations /usr/include,/usr/local/include
2249 without introducing conflicts, since ALL YAZ header files are stored
2250 in subdirectory yaz (under /usr/include for example).
2252 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2253 rather than project/workspace files. We switched because project files
2254 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2257 Changed name of logging function, logf, to yaz_log, to prevent name
2258 clash with some math-log functions. The YAZ header log.h defines logf
2259 to yaz_log (#define) so there should be no incompatibilities by this
2262 Added bend_start/bend_stop handlers for server. These handler are
2263 called on start/stop of server. For windows they are called whenever
2264 a service is started/stopped.
2266 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2267 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2268 in util/yc.tcl. The auto-generated C code structures are, in a few
2269 cases, incompatible with the old decoders. There are differences in the
2270 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2271 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2272 The preprocessor variable ASN_COMPILED is defined when the compiled
2273 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2274 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2275 wish to use the old encoders/decoders you can specify --disable-yc
2278 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2279 version so that it supports both new - and old version of DB Update
2281 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2282 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2283 change. The name parameter can be set to 0 in which no name is specified
2284 for the construction. The macros odr_implicit and odr_explicit sets name
2285 parameter to zero for the construction involved. New macros
2286 odr_implicit_tag and odr_explicit_tag are similar to the others,
2287 except that a name parameter is added. For programmers' that don't use
2288 ODR they probably only need to change the call to z_APDU and z_External.
2290 Added access control facility by interfacing the TCP wrapper library.
2291 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2292 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2293 name of the daemon and enables the access control as specified in
2294 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2296 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2297 den Dool <H.M.vdnDool@kub.nl>.
2299 Added reference ID parameter to most functions in server API - refer
2300 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2302 Changed name of ccl library to libccl.a (was ccl.a).
2304 Fixed bug in decoder for Explain (Category TargetInfo).
2306 Added support for GNU readline in client. Thanks to Jacob Poulsen
2307 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2309 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2310 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2311 IMPLEMENTATION! This change was made to the development version before
2312 the ZIG decided to retract the amendment. If any users MUST be
2313 compatible with the original Update definition, PLEASE CONTACT US, and
2314 we will include a separate definition corresponding to the old Update
2315 ES. Note that because of the change to the ASN.1 of the
2316 TaskPackageRecordStructure we cannot define a single structure that
2317 will support both versions.
2319 * Added const modifier to buffer parameter for some ODR/BER encoding
2320 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2321 completeWAIS, odr_dumpBER.
2323 Fixed bug in client.c which caused a crash when a scanResponse didn't
2324 contain positionOfTerm.
2326 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2327 * will cause an error in a client if a non-YAZ target sends both a
2328 * list of Scan entries and non-surrogate diagnostics.
2330 Retrieval module enhancements. Tag sets may be typed in the reference
2331 to it. From the .abs-file the "tagset" directive takes a third optional
2332 integer type for the tag set referenced. From a .tag-file the "include"
2333 directive takes a third optional type as well. The old "type" directive
2334 in the tag set itself is still recognized but acts as the default type
2337 Backend interface change. Individual Scan terms returned from bend_scan
2338 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2339 in include/backend.h.
2341 Retrieval module enhancements. Multiple tag sets and attribute sets may
2342 be specified in abstract syntax specs. Revised the error/warning for
2343 logging messages reported by the retrieval module when reading the
2346 Object Identifier system (oid_..) changed. The API is backwards
2347 compatible but the oid-routines now allocates new OID's when needed.
2348 Raw OID's may be specified in oid_getvalbyname.
2350 YAZ now uses GNU configure to generate Makefile(s).
2352 * Minor changes in some of the member names of DeleteResultSetRequest and
2353 DeleteResultSetResponse. See include/proto.h.
2355 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2356 and added member 'languages' in TargetInfo (which was missing).
2358 Changed the way attribute sets are handled in the retrieval
2359 module. These are now cached, just like the abstract syntaxes
2362 Changed YAZ so that it links with compiled ASN.1.
2364 Added Explain-schema definitions and mapping routines. The following
2365 Explain categories have been implemented: AttributeDetails,
2366 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2368 Fixed minor bug in Windows version of Server Library.
2370 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2372 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2374 Added EXTERNAL: UNIverse Resource Report (non-standard).
2376 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2377 ENUMERATED and SET OF.
2379 * Added 'const' to some of the char pointer arguments for the
2380 functions, data1_read_node, data1_getelementbytagname,
2381 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2384 Fixed bug in data1_insert_taggeddata - the last_child member of
2385 parent wasn't initialised.
2387 * Changed data1_read_record and data1_read_node so that the supplied
2388 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2389 doesn't refer to any parts of the "SGML"-buffer.
2391 Fixed bug in server library (Windows version of statserv_remove).
2393 * Changed code so that it compiles as C++. The type definition
2394 of Odr_fun which is a member of Odr_arm was changed. The result is,
2395 that an explicit typecast is needed for the fun pointer when
2396 using Odr_arm - as in:
2397 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2399 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2401 Implemented the new structured date and time definition as approved
2402 by the ZIG. Added schemaId element to the specificTag in Espec-1
2403 (also approved at the last ZIG). Thanks to RVDM.
2405 Added some Object identifiers (RVDM).
2407 Changed the Update Extended Service (RVDM).
2409 Added command "refid" to client which specifies referenceId for
2410 the following requests.
2412 Implemented extended service handling for server. See ztest.c
2413 for an example as well as backend.h. New handlers are registerd
2414 in the Init handler.
2416 * Changed interface for sort in server.
2418 Added new members to statserv_options_block. It allows a server
2419 to read options from another source than just the command line. Thanks
2420 to Charles Woodfield.
2422 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2423 renamed to zboolean. Some C++ compilers complained about the name.
2425 Minor changes to gils.abs. Added index 's' (sort) on title
2426 and date/time-last-modified.
2428 --- 1.4pl2 1998/1/30
2430 Fixed bug in server library regarding inetd mode (-i). This bug
2431 was introduced by release 1.4.
2433 --- 1.4pl1 1998/1/29
2435 Added sort facility in client and backend server interface.
2437 Fixed problem with dependencies in Makefile(s).
2439 Fixed bugs for encoders/decoders of extended services and
2442 Implemented sub-tree feature for schemas. Sub-trees are
2443 referenced in *.abs-files. See explain.abs for an example
2444 of the use of this feature.
2446 Modified bib1.att; local attributes for ANY didn't include
2447 ANY itself (only affects use of the retrieval module).
2449 Fixed bug in plain SGML reader in function data1_read_node:
2450 tags with prefix "var" was incorrectly interpreted as variants.
2452 Added feature "sub-schemas" to enable references to - and definitions
2453 of - group of elements.
2455 * Removed member parent from type data1_element (in data1.h).
2457 Implemented function odr_nullval() that returns the value of
2460 * Removed member num_children from data1_node (in data1.h).
2462 Made NT service interface part of the server library. The
2463 function statserv_main uses the NT service when required and
2464 calls the statserv_start / statserv_close routines.
2466 Routine zget_SearchRequest and zget_PresentRequest fills
2467 resultSetName/Id member with "default" instead of "Default".
2469 Fixed memory leak in server. Request queue member wasn't freed.
2471 Fixed nmem_exit so that memory is freed.
2475 Revised the CCL parser utility to be thread safe.
2477 Added function, oid_ent_to_oid, to replace the function
2478 oid_getoidbyent, which is not thread safe.
2480 * Added nmem_init and nmem_exit to initialize and release
2481 NMEM resources. Function nmem_init should be called once in the
2482 initial thread before NMEM/ODR is used. statserv.c and client.c
2483 have been changed accordingly. The change was necessary to make
2484 NMEM thread safe. The NMEM memory pool is shared amongst threads
2485 in a process. Unix-based applications will still work fine without
2488 Added NT Services interface for the the Z39.50 (statserv) Server.
2489 Refer to the ztest.c source on the usage.
2491 Windows 95/NT port using MSVC5.0. Project files are included in the
2494 * Defined new 'global' handle for the retrieval (data1) system. The
2495 new handled, data1_handle, describes the state of the data1 system.
2496 This handle is passed as first argument to virtually all
2497 data1 related routines. The functions data1_create and data1_destroy
2498 creates and destroys a data1 handle respectively.
2500 Added ODR encode stream member to all backend request structures
2501 init, search, scan etc. This stream should be used to allocate all
2502 memory used for the response when thread safe operation is needed.
2504 Changed the comstack utility, cs_addstr, to be thread safe. The
2505 returned hostname string returned by the function is now part the
2508 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2509 function. The cs_straddr takes a COMSTACK handle as argument, so this
2510 function must be used after cs_create and before bind/connect.
2511 This function is thread safe.
2513 Moved test server to 'ztest' directory - generic server code still
2514 in 'server' directory.
2516 Made prefix query (pquery.c) utility thread safe.
2518 Added new function modifier YAZ_EXPORT to 'export' public DLL
2519 functions when using windows (see include/yconfig.h).
2521 Added definitions to the OID database (util/oid.c) (RVDM).
2523 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2525 Added call to ccl_rpn_delete in client program.
2527 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2528 release of RPN structure.
2530 Added support for C++, headers uses extern "C" for public definitions.
2531 With input from RVDM.
2533 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2534 Thanks to Ronald van der Meer (RVDM).
2536 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2538 Added support for private extensions to the OID database
2539 (oid_setprivateoids()). Thanks to RVDM.
2541 Added optional, physical ANY (key replication)
2543 Fixed null-reference problem in GRS-1 output filter.
2545 Proximity operator added to Prefix Query Format (PQF).
2547 In test client command "base" accepts multiple databases.
2549 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2553 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2555 Smallish bug-fixes in the new encoders/decoders (explain).
2557 Bug fixed in DeleteRequest.
2559 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2561 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2563 Added SOIF syntax (using private OID for now) to retrieval module and client.
2565 Added Update extended service.
2567 Added SearchResult-1 additional info structure.
2569 Added optional CCL (ISO8777) interpreter as separate module. Available
2572 --- 1.2 1996/6/10 (1st anniversary release)
2574 Added Summary record syntax. Lightly tested.
2576 Added OPAC record syntax. Untested.
2578 Added ResourceReport service encoders/decoders. Untested.
2580 Fixed bug in z_Unit - wrong tagging on unitSystem.
2582 Fixed bug in the DiagRecs decoder.
2584 Added options for max PDU size and session timeout to frontend-server.
2586 Added documentation of query-language parsers and other supporting utilities.
2588 [frontend-server] Added Attribute set to the bend_scanrequest API.
2590 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2591 surrogate diagnostics were generated.
2593 [retrieval] Allow multiple local values for attribute.
2595 [retrieval] Allow multiple attributes per element in .abs files. index type.
2597 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2599 --- 1.1pl2 1996/4/10
2601 Minor changes, mostly specific to Zebra's requirements (retrieval)
2605 Repaired bug in frontend server when running multiple listening
2606 endpoints in dynamic mode.
2608 z_External() now won't break if a known, ASN.1 value comes encapsulated
2609 in an octet-string. The value will pass through unmodified in an Odr_oct.
2611 Added a bit of code to the demo client to decode & display
2612 ASN.1-structured records represented in the octet-aligned branch of
2613 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2615 Added z_ext_getentbyref() to the ASN module. Doc updated.
2617 * Completed the SCAN definition in the ASN module. This may break SCAN
2618 code based on older YAZ-versions at compile-time. The fix is easy -
2621 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2622 under the SCAN definition. Remember to initialize this, server-people.
2624 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2625 that this does not extend to ODR and ASN.
2627 Comstack allows insertion of established socket (primarily for
2628 inetd-operation of servers). Doc updated.
2630 Front-end server can now start from the inetd in TCP mode. Doc
2633 --- 1.0pl4 1996/1/24
2637 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2638 the rank and record number.
2640 Adjustments to the frontend server.
2642 Fixed diagnostic BER dumper. It ignored the file argument.
2646 Various changes to retrieval module.
2648 Changed the union discriminators of the protocol files from enums to
2649 ints paired with #defines.
2651 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2654 *Changed operator in the RPN structure to 'roperator', again to avoid a
2657 Fixed problems in Explain decoders/encoders.
2659 --- 1.0pl2 1995/12/6
2661 Memory bug in log module fixed.
2663 --- 1.0pl1 1995/12/5
2665 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2667 Bug in Explain DatabaseInfo module fixed.
2669 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2673 The shift to v1.0 signals that we now consider the *core* functionality
2674 of YAZ reasonably stable (the core being more or less equivalent to
2675 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2676 tested (Explain not at all - though that will happen soonish).
2678 Minor changes to code to support Windows port.
2680 Various minor changes after we're getting to use GRS-1 & co. more.
2682 Added Espec-1 format.
2684 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2685 of the protocol and it cannot be selected when encoding (maps into 'string'
2686 when decoding). Needed to talk to some servers.
2688 Demo client can request simple element set names.
2690 Added Diagnostic Format encoders/decoders.
2692 Added simple Close handling to frontend server (no hooks for resource
2693 reporting yet), and demonstration client.
2695 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2697 --- 1.0b3 1995/08/24
2699 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2700 handled incorrectly when records were requested in the searchResponse. This
2701 will only affect you if you use the frontend-server.
2703 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2704 Test-client will ask for and print GRS1. Ztest will return dummy records
2707 Added Explain encoders/decoders to the service-level API. Untested.
2709 Added Extended Services: Item Order encoders and decoders to the Service-
2710 level API. Untested. We could use a recent copy of the pertinent bits
2711 of the ILL protocol to add those bits.
2713 Added diagnostic format 1 encoders/decoders to the service-level API.
2716 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2717 odr_cons.c, which causes a more correct output.
2719 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2720 was always set to 0 when no records were requested in the searchRequest.
2722 * Added better external-handling. This shouldn't harm old code that
2723 *encodes* externals. It can break code that looks for a
2724 'single-ASN1-type' representation, since those types that are known
2725 are now decoded immediately. Look at the SUTRS sample code in
2726 seshigh.c and client.c. Documentation updated.
2728 Handling of structured records in bend_fetchresponse. Length -1 marks
2729 structured record, type is deduced from format field.
2731 --- 1.0b2 1995/06/27
2732 Fairly quick maintenance release to add SUTRS support.
2734 Fixed handling of SUTRS records in the demonstration client.
2736 * Added format field to the bend_fetchrequest and bend_fetchresponce
2737 structures of the backend API (frontend server). When the record is
2738 returned, the value of the format field is mapped to an OID. The
2739 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2740 of the record. The special value VAL_NONE in the bend_request means
2741 that no specific format was requested by the client. Documentation
2742 updated accordingly. Test server (ztest) will return a fixed dummy
2743 SUTRS record if your client requests SUTRS.
2745 Documentation updated accordingly.
2747 You can now set external libraries and RANLIB support in the top-level
2751 First public release.
