3 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
4 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
6 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
7 POSIX/Unix builds .so with major version 4.
9 Remove old LOG_-defines from log.h. They have been obsolete and
10 undefined by default for the last 5 years.
12 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
14 GFS: Remove socket (int *fd) from search_rr handler. The socket
15 descriptor ptr is a facility that allowed a search handler to supply
16 a socket which would serve as a callback - when search was complete.
17 This facility has now been in use for years.
19 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
20 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
21 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
22 returns 'const char *' rather than 'char *. The returned string is
23 read-only and should not be modified by applications. COMSTACK cs_close is
24 now a void function - it no longer returns int. No applications check for
25 the value and the implementations has always returned 0.
27 ZOOM: use size_t for scan hit counts and str size. Functions
28 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
29 occ (hit count) and len (string length) are now of type size_t pointer
30 rather than int pointer. This is to be able to represent large hit counts
31 and to also just to use the proper type for string length (strlen result).
33 New JSON parser. Refer to include/yaz/json.h .
35 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
36 Used to be int in some cases. Many wrbuf_-functions used to return an int
37 indicating some length.. These return values were never used. And so they
40 ODR: odr_malloc, odr_total now takes size_t for size.
42 clone_z_type: fix leak; occurred for encoding failures.
46 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
47 bug was introduced in 3.0.51.
51 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
53 tcpip comstack: fix leak for getaddrinfo.
55 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
56 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
57 Decoding of SRU "path" database is performed by private function
58 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
59 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
61 yaz-client: honor base command for SRU. Change when database setting
62 is applied for SRU and ensure it is kept when a connection is reset.
63 Change also the way errors are displayed or SRU (decoding of packages).
67 Add support for extra request / response data for SRU codecs and GFS.
68 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
69 for extra data response buffer and length. For the GFS, both request
70 and response data (XML) is carried in extra_args and extra_response_data
71 for the search handler. Patch by Ko van der Sloot.
73 ZOOM: For queries that cannot be converted to the specified rpnCharset,
74 ZOOM now returns a diagnostic on the client-side ('invalid query' /
75 10010). This fixes bug #2113.
77 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
78 cmdfile included a 'quit' command that would result in a memory violation.
82 Make a number of functions defined in xmlquery.c static. These have
83 never been declared in a public header file (yaz/xmlquery.h) and was
84 made public by mistake.
86 Improve speed of character conversions (iconv utilities). This makes
87 conversions from MARC-8 faster.
89 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
90 unless type desired is "raw". This will prevent type "xml" from
91 returning ISO2709 .. Which obviously can not be XML parsed.
93 Fix memory leak in ZOOM that would occur if option apdulog was used
94 on a re-used connection.
96 Frontend server logs HTTP requests.
98 Frontend server now sends Z39.50 close when it times out (sesssion has
99 been idle for too long). Versions 2.0.30 and earlier also sent close.
100 But due to a mistake this was disabled in all versions after that, i.e.
101 the server would just close the socket immediately.
103 yaz-client emits a better message when receiving an unrecognised
104 userInformationField.
106 Skip zero-length subfields when decoding ISO2709. This rare case happens
107 if a record has two FS characters in a sequence. Without this patch
108 there would be a reference beyond char array in using_code_len fragments
111 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
113 --- 3.0.48 2009/08/28
115 The show command offered by the zoomsh command now takes a 3d optional
116 parameter type which is what is passed to ZOOM_record. If the type
117 argument is omitted, "render" is used.
119 RPN to CQL conv may use USE string attributes (bug #2978).
121 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
123 --- 3.0.47 2009/07/08
125 Function yaz_xml2query allows a diagnostic element in the PQF XML
126 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
127 code and additional info respectively.
129 The BER BOOLEAN is now the integral type Odr_bool which still happens
130 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
131 typedef'd to Odr_int. This is still an integral 'int', but it may be
132 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
133 ASN-1 compiler as well as programs has been updated to use the new types.
135 --- 3.0.46 2009/06/08
137 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
138 only the bibliographic record was rendered. For type=opac, an OPAC
139 record is only returned if it is present.
141 iconv: small fix for encoding of advancegreek.
143 yaz-client: avoid double display of SRU/SRW records (bug #2798).
145 yaz-client: option auto_reconnect=on really reconnects.
147 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
149 server: avoid null ptr ref for for yaz_poll errors.
151 build: fix RPM build for RHEL 5.3.
153 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
155 --- 3.0.45 2009/03/31
157 Fixed bug #2709: TCP connect returns Invalid argument.
159 Fixed compilation for mingw.
161 Honor charset for raw records (ZOOM_record_get).
163 Fixed use of errno for threaded mode that was seen on Solaris 10.
165 Fixed argument passing with blanks in value for Windows Service.
167 Disable YAZ' own log rotate by default (no 1 GB limit).
168 The variable l_max_size which specifies the log file limit is set to 0
169 (DISABLED): This is due to the fact that YAZ is most often deployed using
170 logrotate. Also YAZ can not perform log rotate because of unsufficient
171 permissions (setuid).
173 --- 3.0.44 2009/02/17
175 List supported encodings in man page for yaz-iconv.
177 Fixed missing SSL libs for --libs output
179 Re-established OID record syntax application-xml. Nobody should use it
180 but we don't want to change soname because of this symbol being absent.
182 --- 3.0.42 2009/02/02
184 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
186 Added member named_result_sets for init handler struct for the GFS. This
187 allows a server to disable named result sets.
189 Removed OID record syntax application-xml.
191 Added support for rule-based transliterator for ICU wrapper of YAZ.
193 Fixed bug #1902: yaz-icu XML output.
195 Make YAZ checks Emacs friendly.
197 BITSTRING value shows value. Bug #2346.
199 ISO2709 decoding: skip control characters from indicator data.
201 Omit sort key by default in yaz-icu's output.
203 Allow combined single char options (again) for YAZ' options function.
205 Utility yaz-marcdump got option to display YAZ version (-V).
207 Allow YAZ to use ICU 3.4.
209 Added new ICU test case which illustrates removal of diacritics.
211 --- 3.0.41 2008/12/29
213 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
215 --- 3.0.40 2008/12/29
217 For configure, using option --without-xml2 also disables Libxslt/Libexslt
220 Fixed bug #2352: yaz-marcdump crashes for certain record.
222 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
224 Added support for Danmarc2 to UTF-8 conversion.
226 Added support for ISO5426 to UTF-8 conversion.
228 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
229 implementation version.
231 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
233 --- 3.0.38 2008/11/10
235 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
236 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
238 ZOOM C now interprets databaseName option for ZOOM connection as path
241 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
243 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
245 Dummy Libxml2 types no longer defined in headers of YAZ'.
247 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
250 --- 3.0.36 2008/09/26
252 Various ODR chapter fixes.
254 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
256 Added missing source for Windows compilation, mutex.c.
258 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
260 For SRU connections in ZOOM all records up to "count" are now fetched.
262 Fixed crash in generic frontend server (and yaz-ztest) which occurred
263 in Windows due to bad error handling for Libxml2.
265 Added facility for sending arbitrary records (ASN.1 any) using
266 ZOOM C's Extended service update. Patch by Sam Reynolds.
268 New options for ZOOM C's connection, logapdu which makes ZOOM log
271 --- 3.0.34 2008/06/18
273 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
275 --- 3.0.32 2008/06/12
277 Fixed memory violation that could occur when decoding UTF-8. This bug
278 was only present in 3.0.30 of YAZ.
280 --- 3.0.30 2008/06/06
282 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
283 GNU TLS is used by default (if found).
285 yaz-ztest returns OPAC records if a client asks for OPAC.
287 Improved speed of MARC-8 encoding.
289 Added support for lossy and loss-less MARC-8 encoding.
291 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
293 Added new Windows Service wrapper (sc).
295 yaz-client's itemorder command may now send a file.
297 Fixed yaz-marcdump to allow the use of NS prefix for record element.
299 Added new function yaz_log_xml_errors.
301 Allow (but warn) unknown XML attributes in MARCXML parsing.
303 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
305 The UTF-8 to MARC-8 conversion now uses a different set of characters
306 for Greek symbols. Bug #2120.
308 --- 3.0.26 2008/02/21
310 Added yaz_daemon (daemon.h).
312 Fixed bug #2068: pkg-config trouble
314 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
316 --- 3.0.24 2008/01/28
318 Document --with-xml2 option.
320 Added OPAC XML XSD (etc/opacxml.xsd).
322 Allow glob mask for name attribute in retrieval element for the
323 generic frontend server's retrieval facility.
325 Changed yaz_poll_poll to return yaz_poll_except for all returned events
326 except POLLIN/POLLOUT.
328 Fixed error handling in cs_listen. Bug #2037.
330 --- 3.0.22 2008/01/20
332 Fixed version in yaz/yaz-version.h.
334 Fixed bug #2027: Crash when closing connection.
336 Changed configure so that ICU support is only enabled if only ICU
337 and Libxml2 is available (because the ICU chain is XML based).
339 --- 3.0.20 2008/01/15
341 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
342 is built. Only this DLL depends on the ICU runtime.
344 yaz-ziffy is no longer part of YAZ. It is distributed separately by
345 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
347 Changed license of CCL module to 'Revised BSD'. After consultation with
348 remaining members of the original EUROPAGATE consortium, we are re-issuing
349 the CCL module without a separate license. The software was developed by
350 Index Data as part of a research project. The special license was included
351 to help feed usage information back to the project consortium to support
352 project evaluation. At this time, the project consortium has long-since
353 disbanded, and the majority of the original principals have retired. At the
354 same time, we have significantly modified the software during the following
355 years, to the point where very practically no original code remains. To
356 simplify re-use of the software, we have contacted those members of the
357 consortium who could be reached, and agreed to re-issue the module as a
358 proper part of the YAZ package.
360 Tcl scripts uses /usr/bin/tclsh as preferred shell.
362 CQL closer to being version 1.2 compliant. CQL also allows free-form
363 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
366 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
367 bug could make Extended services handling crash in the ZOOM layer. This
368 bug was only present in YAZ 3.0.18.
370 --- 3.0.18 2007/12/19
372 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
375 yaz-marcdump reads and writes collection wrapped records.
377 Handle OPAC for record conversion module.
379 Fixes for ICU wrapper.
381 Allow ICU libs to be controlled with --with-icu .
383 --- 3.0.16 2007/11/12
385 Added yaz_poll which is a wrapper for select/poll. When poll is available
386 and non-buggy, it is used, by yaz_poll . This allows more than 1024
387 sockets to be in use.
389 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
390 functionality through an XML based configuration (ICU chain). This system
391 is useful for search facilities such as Pazpar2 and Zebra that needs to
392 perform tokenization of indexed material. The ICU code in a separate
393 library libyaz3_icu.a.
395 Added HTTP tunnel facility for COMSTACK, bug #1752.
396 This is a facility that allows a Web proxy, such as squid, to tunnel
397 Z39.50 traffic. This facility is "transparent" to must applications
398 using YAZ. It's enabled by using pseudo transport connect: followed by
399 the proxy address, followed by command, then follwed by he regular
400 "virtual" addresss. For example,
401 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
403 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
405 --- 3.0.14 2007/09/21
407 Fixed bad memory reference in ZOOM_record - cuased by member not being
408 initialized. This was a problem only in YAZ 3.0.12.
410 Fixed bug in conversion from MARC to XML: Non-XML characters in control
411 fields were not removed.
413 Changed the way C code is generated from codetables.xml. Made a MARC-8
414 conversion trie for each characterSet section rather than codeTable.
415 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
416 of codetables.xml from Larry Dixson, LOC. Bug #1464.
418 --- 3.0.12 2007/09/12
420 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
421 from ZOOM_record_error).
423 ZOOM C function ZOOM_record_get returns record schema for type="schema".
425 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
427 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
429 Better SRW-to-Bib-1 diagnostic mapping.
431 ZOOM C and yaz-client announces SRU version 1.2 by default.
433 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
436 Fixed in yaz_sru_decode to allow other version than 1.1.
438 --- 3.0.10 2007/08/22
440 Added support for SRU scan for ZOOM.
442 Added support for the use of the older versions or Extended Service
443 Update in ZOOM. To faciliate this, an option "updateVersion" may be
444 set to the version , 1=first, 2=second, 3=third. The third version is
445 what ZOOM C has used so far. And that, obviously, is the default.
447 Added support for CCL queries in Z39.50 queries sent to the GFS (and
448 therefore in Zebra and in SimpleServer-based applications). The new
449 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
450 qualifier file used to transform incoming CCL queries into Type-1 RPN,
451 which is passed into the back-end search callback function.
453 Added support for HTTP Basic authentication in clients: the SRU/W
454 codec encodes the username/password elements of the PDU structure
455 appropriately, and these may be set using the "user" and "password"
456 options in ZOOM-C applications (the same options that are used for
457 Z39.50 authentication).
461 Fixed bug #1208: SSL appears to be broken in ZOOM.
463 Fixed bug #1206: Libxml2 include path weirdness.
465 Added oid_name_to_dotstring.
467 Allow elementSetName to be specified for ZOOM C record update.
469 Allow waitAction to be specified for ZOOM C based for Extended Services.
471 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
472 syntax OID. Bug introduced in YAZ 3 series.
474 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
478 Fixed bug #1157: yaz-client does not read .yazclientrc from current
479 directory. yaz-client now reads commands from file given by option -f
480 if specified; then tries to read .yazclientrc in current directory.
481 Failing that, it reads .yazclientrc from user's home directory.
483 Added support for correlationInfo Note and ID for Record Update via
486 Added yaz-client command querycharset which specifies character set for
487 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
488 (termListAndStartPoint).
490 Charset ISO5428:1984 is an alias for ISO5428-1984.
492 Implemented a way to perform scan in a result set using Z39.50. This
493 is achieved by attaching the result set name in the characterInfo
494 (type InternationalString) of OtherInformation in the Scan Request PDU.
495 The result set is identified in the otherinformation by the new OID:
496 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
497 This allows for scan in result set and faceted search . Zebra did some
498 of this in the APT term using attribute type 8 and value being result
499 set. Using the OtherInformation approach for this is cleaner and easier
500 to work with in proxies and the like. This facility can be used in
501 yaz-client using new command setscan which takes a result set as first
502 argument, start position (APT) as second.
504 Changed decoding of SRU XML packed records to deal with servers that
505 have recordData with XML data with multiple root nodes. Also make
506 comparison for recordPacking case insensitive. Again, one server
507 returns "XML" where others return "xml".
509 For SRU responses allow Content-Type application/xml as well as text/xml.
513 Fixed bug in character set conversion of BER strings. Bug introduced
518 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
520 For OID class, use oid_class consistently.
522 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
525 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
526 character set for bibliographic information interchange". By Giannis Kosmas.
528 Added documentation on new OID API.
532 Changes to generic frontend server interface: added new member
533 'query_charset' for bend_initrequest structure. A backend init handler
534 should set this member to its native character set for query terms.
535 When defined, the frontend server logic will announce this character set
536 to a client if the negotiationModel bit is set by the client. All server
537 implementors are encouraged to specify this. If a backend server does not
538 specify this a warning is issued using yaz_log(YLOG_WARN,..).
540 Added CCL utility to remove terms (stop words) from resulting RPN
541 tree. This is handled by functions with prefix ccl_stop_words_ .
543 New ZOOM C option, "rpnCharset", which allows client-side conversion of
544 terms in RPN queries.
546 Clean-up the CCL API. Moved some internal structures from ccl.h to
547 private header cclp.h. Changed ccl_parser_create so that a Bibset must
548 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
549 This is replaced by ccl_parser_find_str which takes a string instead.
551 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
552 libyaz.la is the core of YAZ except the generic frontend server and
553 does not depend on POSIX threads anymore. libyaz_server.la is the
554 generic frontend server facilities and uses POSIX thread functionality
555 if available. The libyaz.la no longer depends on POSIX threads because
556 the number of global structures is limited. NMEM no longer re-uses blocks
557 between threads ; it simply free's memory immediately but allocates in
558 "large" chunks as usual. We don't expect any performance penalties
559 because of this. The yaz_log system is still using a global log_level so
560 caution must be taken when modifying it with yaz_log_init_.. +
561 yaz_log_mask_str. This, however, should not cause any trouble because
562 these functions are called during initialization of application code
563 anyway. `yaz-config --libs server` returns libs for server applications;
564 `yaz-config --libs` returns libs for non-server applications.
566 New OID database - with public definitions in oid_db.h. Removed old OID
567 database including the head oid.h and definitions such as enum oid_value
568 and struct oident. The new OID database uses the same string names as
569 before but the 'protocol' is gone. There are now only two representations
570 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
571 converts from string to OID; functions with prefix yaz_oid_to_string
572 converts the other way.
574 Change to emit_term() in CQL-to-PQF query translation: when a term has
575 the /regexp relation modifier, do not process it for leading and
576 trailing "^" and "*", which have quite different meanings in regular
579 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
580 write handlers no longer carries a 'last' parameter. This will make
581 yaz_iconv flush "less" characters. A flush is performed by call to
582 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
584 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
585 removed, because function yaz_query_to_wrbuf does the same.
587 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
588 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
590 Deprecated MARC utility functions removed.
592 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
595 Branch split: YAZ_2_1_55_branch
597 --- 2.1.54 2007/03/16
599 Fix to ZOOM-C so that transparent reconnection is properly handled on
600 connections that are in asynchronous mode.
602 Fixed compilation on OpenBSD 4.0.
604 Large strings in GRS-1 records are now properly displayed in yaz-client.
606 Added character conversion support for "advancegreek"; based on patch from
609 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
610 sequence is met. Before the error was not set so it would be unknown.
612 Adjust yaz-marcdump MARC reader so that it skips until record separator
615 --- 2.1.52 2007/03/07
617 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
618 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
619 fd_set structure used as a bitmask for the FDs to be selected on.
621 Using ACX_PTHREAD macro to check for POSIX threads.
623 Fixed have-vsnprintf check.
625 --- 2.1.50 2007/02/23
627 Fixes for configure on BSD. Bug #900.
629 Added snprintf/vsnprintf wrappers for systems that don't have
630 limits (heavens forbid).
632 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
633 created before all previous tasks were completed and removed from the
634 task queue, the new task could be removed by a mistake.
636 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
638 Implemented pass-through CQL-to-PQF conversions. Bug #861.
640 Fixed bug #832: Problem with MARC/charset in yaz-client.
642 Fixed bug #668: save command line history for yaz-client.
644 Fixed bug #830: pkg-config support.
646 --- 2.1.48 2007/01/23
648 Extended ZOOM result set options with two options that may be read by
649 a client: resultSetStatus and presentStatus with values as specified for
651 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
653 Fixed bug #827: Using SSL fails on Debian etch.
655 Fixed bug #826: Weird looking chars for set of MARC records.
657 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
658 that is treated as an ItemOrder with itemRequest being an XML document
659 external. The value of "doc" is the content.
661 Extended the GFS search facility. New member of bend_search_rr
662 'estimated_hit_count' signals that hits is known to be an estmate
663 (higher or lower than real hit count). New member 'partial_resultset'
664 signals that the search was partial (hit count is lower or equal than
665 real hit count). For Z39.50, the information is stored in resultSetStatus
666 member of SearchResponse APDU. For SRU, the information is signalled
667 via SRU diagnostic 59: "Result set created with valid partial results
670 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
672 --- 2.1.46 2007/01/13
674 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
676 Added ZOOM_connection_peek_event.
678 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
679 the following new functions:
680 ZOOM_event_nonblock, ZOOM_connection_process,
681 ZOOM_connection_get_{socket,mask,timeout},
682 ZOOM_connection_fire_event_{timeout,socket}.
683 The existing blocking event handler, ZOOM_event, is a wrapper for the
684 + blocking ZOOM_event_sys_{poll,select}.
686 Implemented function ccl_xml_config which parses XML version of CCL
687 configuration (bug #798).
689 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
691 Added timings utility (yaz/timing.h)
693 --- 2.1.44 2007/01/03
695 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
698 Fixed bug #779: Rotation of apdu.log fails.
700 Fixed for character set conversions:
701 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
702 Honor G1 set in MARC-8 decoding.
704 --- 2.1.42 2006/12/17
706 Fixed bug #775: char conversion does not handle Alternative UTF-8
709 Implemented function yaz_marc_read_line which parses MARC line format
710 records. There is a wealth of formats out there. So far, this function
711 reads line records produced by yaz_marc_write_line.
713 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
714 more generic and easier to remember(!) options: -i format and -o format
715 which specifies input format and output format respectively - where
716 format is one of "marc", "marcxml", "line", "marcxchange".
718 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
719 does not print anything except warnings for records.
721 For yaz-marcdump, added support for MARC split into files (-s) with a given
724 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
725 spec, at http://www.loc.gov/standards/sru/record-update/
726 This has changed the binary layout of the following structs:
727 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
728 bend_update_rr . Patch by Ko van der Sloot.
730 Added GFS utility function bend_assoc_is_alive which returns 1 if
731 association is still alive (client is connected); 0 otherwise (client
732 closed connection). This allows busy servers to stop working for
735 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
736 been a separate piece of software. This version of ziffy has been modified
737 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
739 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
741 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
742 Client code may now interrogate options such as "init_opt_sort" to
743 find out whether the server claims to support various options.
745 --- 2.1.40 2006/11/27
747 Added utilities yaz_{set,get}_esn to set/get element set name from
750 Removed the build of libyazthread.la. The libyaz.so is the threaded version
751 of YAZ and has been so since YAZ 2.1.10.
753 Implemented ZOOM_record_error which returns error information for
754 record (surrogate diagnostic).
756 --- 2.1.38 2006/10/31
758 Updates for SRU Update by Ko van der Sloot:
759 1. Changed name from "operation" to "action"
760 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
761 versions in the code, marked as 'backward compatible'.
762 3. Added diagnostics for SRU Update.
764 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
766 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
768 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
770 For GFS, fixed problem with SRU diagnostic 'First record position out of
771 range' being issued for 0 hits.
773 zoomtst10 part of Windows Build.
775 --- 2.1.36 2006/10/13
777 Implemented yaz_filepath_comp which splits a path into file path
778 components (required by Zebra 2.0.3+).
780 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
781 BSD inspired license until now so this should not have any real impact on
782 anybody. See http://www.opensource.org/licenses/bsd-license.php
784 Fixed bug #687: Missing log lines.
786 Fixed bug #678: CQL to PQF translation does not preserve double-quote
789 Fixed bug #689: SRU diagnostics to be added.
791 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
792 whether a connection is idle (no more work do do).
794 --- 2.1.34 2006/10/04
796 Change type of optval from long to int for invocation of setsockopt with
797 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
799 Added support for specifying the max log file size for the Generic
800 Frontend Server. The size is given with option -r.
802 --- 2.1.32 2006/09/21
804 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
806 --- 2.1.30 2006/09/17
808 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
811 Fixed bug in Generic Frontend Server that could cause a server to stop
812 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
814 For the generic frontend server, the maximum record size is used as maximum
815 size of incoming packages (SRU + Z39.50). The value until was previously
816 only used in Z39.50 Init negotiation and, later, in a session controlled
817 sizes of records returned. This is controlled using -k option. It can be
818 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
820 --- 2.1.28 2006/09/04
822 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
825 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
827 New option for yaz-marcdump -lpos=value which allows setting a portion
828 of MARC header to a certain value.
830 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
832 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
833 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
835 --- 2.1.26 2006/08/15
837 Fixed problem with SRU mode type (soap, get, post) for yaz-client
840 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
842 --- 2.1.24 2006/08/08
844 Fixed MARC ISO2709 encoding routines to deal with character set
847 Minor changes to GFS logging. Database included in search request log
850 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
851 cached/multiple records.
853 Shared libraries are built by default on Unix+configure.
855 Changed cql2pqf transformation to use a different evaluation order. The
856 new order is: always, relation, structure, position, truncation, index
857 and relationModifier. Old order was: always, relation, relationModifier,
858 structure, index, position, truncation. Note that the the latter ones
859 override former ones for identical attributes.. The new scheme means that
860 it is possible to override any existing attribute with a relationModifier.
861 And also that it is possible to override everything for the index rule
862 (except the ones listed in relationModifier). No order is perfect but this
863 one, we believe, covers more real cases.. The "always" should have been
864 called "default", since the attributes there can be overridden with all
867 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
868 compilation phase, but also for yaz-config --cflags output. This allows
869 us to have public headers with Libxml2 stuff in them . It should also,
870 eventually, make Libxml2 checks redundant in packages using YAZ, such
873 --- 2.1.22 2006/06/15
875 Changed SRU update structure bend_update_rr so that SRU diagnostics are
876 stored in uri, message and details.. Previously diagnostics were stored
877 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
878 compatibility.. but he's probably the only one affected, so.
880 Added support for CCL, compiled on the client side, in ZOOM-C. This
881 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
882 input; the resulting query objects can be used for for searching with
883 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
885 YAZ' configure searches for OpenSSL by default.
887 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
888 SL_CTX_use_certificate_file. See
889 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
890 for more info. Thanks to Ko van der Sloot.
892 --- 2.1.20 2006/06/02
894 Bug #600: SRU GET, POST support for yaz-client. Introduced
895 command 'sru' which selects method SOAP/GET/POST.
897 Allow missingValueAction to be specified for the sortspec string -
898 function yaz_sort_spec. By default, the missing value action is null.
899 Use ! to specify "abort". Use = followed by stringvalue to specify default
902 Ensured that Present-handler (if defined) is called in GFS before any call to
903 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
904 searchRetrieve requests.
906 Documentation for YAZ is now based on the Docbook XML/XSLT using
907 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
908 is no longer depending on jade/openjade or docbook-to-man scripts.
909 PDF is no longer part of the distribution - but can optionally be
910 made using DSSSL/jadetex or FOP.
912 Added retrieval handling support in Generic Frontend Server to support
913 conversion between MARC/XML as well as XSLTtransforms. See
914 etc/yazgfs.xml for an example.
916 Added Authentication support to Generic Frontend Server in SRU
917 mode. Authentication using HTTP Basic is supported, as is the use
918 of 'x-username' and 'x-password' parameters in the request itself.
920 Added support for a new character set MARC8s identical to MARC8 except
921 that it converts combined characters to single Unicode characters in the
922 Latin-1 range (when possible).
924 --- 2.1.18 2006/04/24
926 ASN.1 compiler 0.4: generates brief Doxygen file header for
927 generated .h/.c files.
929 Utility yaz_iconv now supports conversion to MARC-8.
931 New facilities for the MARC module. The reading - and writing of
932 content are separate methods for the yaz_marc_t handle. The following
933 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
934 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
935 format). Write functions have prefix yaz_marc_write_.. The existing
936 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
937 available. Removed support for OAI-MARC and simplexml (not the
938 simplexml from PHP5).
940 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
941 to be returned for this connection.
943 --- 2.1.16 2006/03/31
945 Allow multiple languages and charsets to be specified with
946 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
947 negcharset iso-8859-1,utf-8
949 Translation of proximity nodes from CQL into PQF now works.
951 Moved to automake 1.8, 1.9.
953 Added function yaz_log_set_handler which allows a log handler to be
954 installed. This handler will be called for all log messages. Output
955 to file is also produced; but that can be disabled by passing NULL
956 fname to yaz_log_init_file.
958 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
960 For SRW (including GFS), accept application/soap+xml as content-type
963 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
964 produces NO stylesheet reference even if a default stylesheet is specified
967 --- 2.1.14 2006/03/14
969 Updated Windows package to include yazd.dll + yazd.lib for the
970 Development component.
972 If the environment variable YAZ_LOG is set, then it is used as a
973 string indicating the default level of logging to use if not
974 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
975 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
976 used as before. So, for example, to omit warnings from YAZ logging,
979 cql_transform() now map structure and other attributes before indexes,
980 so that index-specific structures and other attributes can override
981 defaults. So now a combination of mapping specifications such as:
983 index.dc.date = 1=date-modified 4=5
984 does the right thing.
986 cql_transform() now also respects the "always" mapping specification,
987 which establishes an initial set of attributes to be used for all
988 terms except where overridden by more specific attributes associated
989 with the index, relation or modifier.
991 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
992 which mode to use; one of "post", "get" or "soap" (SRW, default).
994 Fixes for yaz_iconv routines: changed trie-based character set conversions
995 to use only non-negative values for bit fields due to Sun's C compiler not
996 supporting negative values.
998 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
999 sequences where not read correctly. Fix by Rustam Usmanov.
1001 Updated win/makefile to use options, settings which makes things
1002 compile with VS C 2005.
1004 --- 2.1.12 2006/02/01
1006 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1008 In ZOOM socket code, use select instead of poll on MacOSX.
1010 ZOOM-C now support client-side compilation of CQL into RPN that is
1011 sent to the server, enabling CQL to be used against all Z39.50
1012 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1013 ZOOM_query object, and submit it using ZOOM_connection_search().
1014 The CQL-to-RPN translation uses a configuration file, the name of
1015 which must be specified in the Connection's "cqlfile" option.
1017 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1018 function, which takes as its start-term parameter a ZOOM_query object
1019 (which may have had either CQL or RPN set into it).
1022 --- 2.1.10 2005/11/29
1024 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1025 GFS to support this as well. Backend handler, bend_srw_update, does the
1026 update work. Code contributed by Ko van der Sloot.
1028 Allow retrieval of Search Result-1 information in ZOOM by the use of
1029 options that are attached to a result set. ZOOM documentation updated
1032 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1033 UTF-8 conversion. Patch by Raj Patel.
1035 Added option -m to GFS to control formatting of timestamps in log file.
1037 Added 'exit' as synonym for 'quit' in yaz-client
1039 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1040 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1041 for the new members. Patch by Ko van der Sloot.
1043 Added support for SRU POST. It is supported for content-type
1044 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1046 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1047 Instead make the library libyaz.la multi-threaded. Threading as a whole
1048 can still be disabled by configure option --disable-threads. Previosly,
1049 with older GLIBCs there were problems with MT libs under Apache. This
1050 has now been fixed a long time ago.
1052 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1055 CQL module modified to be case insensitive for relations/indexes/operations.
1057 Fixed bug in CQL transform code: incorrect value relationModifieder
1060 Added 'show all' command for yaz-client which retrieves all results
1063 Added new yaz-client, xmles, which takes a (private) OID and
1064 a document to be sent as an extended service request.
1066 Describe new yaz-client commands wait_response and set_auto_wait.
1068 Increase TCP/IP listener backlog from 3 (which I am guessing was
1069 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1070 that the socket will queue as many incoming connections as it's able
1071 to handle ongoing connections. In other words, it will never now
1072 refuse a connection that it would be able to handle merely because
1073 it's not got around to accepting() enough of the pending connections
1074 yet. This is the behaviour anyway under Linux, where the listen()
1075 argument is ignored; but not under BSD and on systems such as
1076 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1077 YAZ-based servers should now be uniform across operating systems in
1080 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1081 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1082 This allows yaz-marcdump to read large MARC batches (>2 GB).
1084 Modified all YAZ source files - except the source which is auto-generated
1085 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1088 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1089 corresponding to the existing *_setl() function. These allow option
1090 values containing arbitrary valuues.
1092 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1093 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1094 except that it returns an indicator of whether or not the sort
1095 criterion was accepted (0 for OK, -1 for invalid).
1097 --- 2.1.8 2005/06/07
1099 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1100 MARC output rather than returning "new" buffer.
1102 yaz-client warns about unknown init options.
1104 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1106 --- 2.1.6 2005/05/24
1108 Added support for SRW sort in Generic Frontend Server. Patch
1109 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1110 sortKeys - or NULL if none is provided.
1112 Fixed bug #307: It was impossible to specify indefinite/no timeout
1113 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1116 Added support for multiple languages and charsets to be specified in
1117 ZOOM. Each charset/language is separated by a blank. If negotiation is
1118 in effect in init-response, Option
1119 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1120 Code based on patch by Vasiliy Osadchuk.
1122 Fixed bug #306: infinite recursion that occurred when calling
1123 yaz_log_level_init as the first call (before other log level or
1126 Fixed bug in scan handling in front end server: if preferred-Position-In-
1127 Response was non-present, a NULL pointer referece was performed.
1129 --- 2.1.4 2005/04/26
1131 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1132 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1133 now defined for all those error codes. So instead of putting 109 in
1134 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1135 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1137 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1140 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1142 Program yaz-client now exits and produces an error message if multiple
1143 Z39.50 servers are specified on the command line (none or one allowed
1146 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1149 --- 2.1.2 2005/03/16
1151 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1153 Fixed bug #272: Preserve spacing for CCL terms.
1155 --- 2.1.0 2005/03/14
1157 Added support for virtual hosts and multiple backend servers for
1158 the YAZ frontend server. The configution is XML based and
1159 support specificition of CQL to RPN mappings and explain information.
1160 See section "Virtual Hosts" in the YAZ manual.
1162 Extended OPAC display utility. OPAC display utility renders
1163 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1164 to supplement yaz_marc_decode_wrbuf.
1166 Fixed a bug in MARC decoder that could caused it to crash for some
1167 invalid MARC records. More diagnostics and warnings where added in
1168 XML output (warnings, etc are stored in comments).
1170 --- 2.0.34 2005/02/08
1172 Fixes for UNIX domain sockets. Bug #261.
1174 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1176 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1177 Added yaz_marc_subfield_str which defines subfield lead string which is
1178 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1179 yaz_marc_endline_str which defines end of fields string used in
1180 YAZ_MARC_LINE format. Default string is newline.
1182 Experimental support for MarcXChange. This format can be produced
1183 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1184 http://www.bs.dk/standards/MarcXchange.xsd
1186 Added yaz-client commands scansize that sets maximum number of
1187 entries to be returned by scan.
1189 --- 2.0.32 2005/01/11
1191 Added support for SRW scan in yaz-client and Generic Frontend Server.
1193 * Added whereInList member to SRW Scan Term.
1195 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1197 Fixed NMEM system to return aligned blocks on the smallest boundaries
1198 that are suitably aligned for all possible types on the particular
1199 architecture YAZ is being built for.
1201 --- 2.0.30 2005/01/04
1203 Fixed numerious warnings that was issued with newer versions of GCC.
1205 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1206 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1209 Make YAZ Generic Frontend Server slightly faster.
1211 Enhance (and reduce) logging for Generic Frontend Server.
1213 Revert YAZ log system so that it flushes every write operation
1214 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1216 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1217 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1218 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1219 will effectively disable old definitions.
1221 --- 2.0.28 2004/11/09
1223 Added yaz_log_time_format which specifies log format using
1226 Added yaz_log_module_level which returns mask for a module. Value
1227 is non-zero mask a if module is enabled; zero if disabled.
1229 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1230 in include/yaz/cql.h.
1232 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1234 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1236 Fixed bug #172: RPM builds does not enable SSL.
1238 Doxyfile.in part of dist. Doxyfile generated by configure.
1240 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1241 are given and the corresponding component does not exist.
1243 Extend CCL documentation in YAZ reference. Describe r=r.
1245 --- 2.0.26 2004/10/01
1247 Fixed MARC->MARCXML conversion to properly deal with
1248 fields, subfields, indicators having non-ASCII characters.
1250 Fixed MARC->MARCXML conversion so that ASCII control characters
1251 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1254 Added YAZ GFS support for conversion from Z39.50 surrogate
1255 diagnostics to SRW surrogate diagnostics.
1257 Bug fix: YAZ GFS did not return schema in explainResponse.
1259 --- 2.0.25 2004/09/30
1261 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1262 now converts recordSchema to elementSetName as well as schema URI.
1264 Fixed bug in COMSTACK that prevented HTTP request packages from being
1267 --- 2.0.24 2004/09/29
1269 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1270 does not require white-space before and after the dash in a range, e.g.
1271 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1274 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1275 due to new GCC removing "redundant" code.
1277 Added yaz-client commands scanpos and scanstep that sets preferred
1278 position and step-size for scan.
1280 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1282 Added CCL utility ccl_qual_buf which parses one or more CCL
1283 spec lines in a buffer.
1285 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1286 of name and value - ignoring empty lines and comments.
1288 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1290 Added odr_get_element_path which returns current element path for an
1291 ODR handle. This utility is useful in error handling or user-defined
1294 Added ODR_PRINT utility odr_set_stream which is is a more generic
1295 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1296 to a write function and pointer to close function. The close function - if
1297 non-NULL - will be called during odr_destroy.
1299 Fixed bug in CCL parser where truncation char was not removed from
1300 right side when truncation=both was in effect.
1302 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1305 --- 2.0.23 2004/08/11
1307 Fix buffer overrun in CQL parser when dealing with proximity (%).
1309 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1310 to UTF-8/UCS conversion is now only based on codetables.xml.
1312 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1314 --- 2.0.22 2004/08/06
1316 Add support for more "commit changes" in ZOOM (uses Extended Services).
1318 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1321 Yet another small fix for configure of SSL.
1323 --- 2.0.21 2004/05/14
1325 Fix SSL libs for configure when --with-openssl=DIR is given.
1327 --- 2.0.20 2004/05/10
1329 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1331 SSL comstack now uses yaz.pem certificate file on server side
1332 by default. Certificate filename can be configured by calling
1333 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1335 Fix bug regarding multiple calls to ZOOM_connection_connect.
1337 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1339 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1340 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1342 ZOOM now allows inspection of X509 peer certificate for verification.
1343 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1345 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1346 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1347 as "modular" but it simplifies things.
1349 Added cs_get_peer_certificate to that returns peer X509 PEM.
1351 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1352 NULL if SSL is unavailable.
1354 Documentation about MARC decoding tools.
1356 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1358 --- 2.0.19 2004/03/30
1360 Rename CHANGELOG to NEWS to follow GNU style packing.
1362 Fix bug with missing initialization of member in init_diagnostics.
1363 This bug affects threaded version of GFS server.
1365 --- 2.0.18 2004/03/20
1367 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1370 Ensure zlib.dll is packed with Windows install.
1372 --- 2.0.17 2004/03/17
1374 Fix encoding of xsd:string to use text instead of CDATA.
1376 Fix endless loop in CQL parser with unbalanced ".
1378 Use a more compact way to store MARC-8 conversion tables.
1380 --- 2.0.16 2004/03/16 Debian only
1382 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1385 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1390 --- 2.0.15 2004/03/01
1392 Another fix for decoding of XML packed records.
1394 --- 2.0.14 2004/02/25
1396 Fixes for Chunked encoding. White space not ignored after length spec.
1398 Update NS and use default NS for SRW diagnostic elements.
1400 --- 2.0.13 2004/02/23
1402 Implement ZOOM_resultset_cache_reset which resets record cache.
1404 Implement ZOOM_resultset_sort which sorts a result set.
1406 Implement chunked HTTP transfer.
1408 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1410 --- 2.0.12 2004/02/16
1412 Added member 'schema' to bend_explain_rr structure so that backend
1413 can specify explain record identifier. Defaults to Zeerex 2.0.
1415 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1417 --- 2.0.11 2004/02/16
1419 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1422 Added init command for yaz-client which sends "extra" init request.
1424 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1425 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1427 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1429 Make ZOOM error code for "invalid query".
1431 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1433 --- 2.0.10 2004/02/05
1435 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1438 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1440 Added option -p <file> to make Generic Frontend Server to write PID file.
1442 Added option -D to put Generic Frontend Server in background on its own.
1444 Make ZOOM C recognize option "password". If unset, "pass" is used
1445 (for backwards compatibility).
1447 Fixed a bug in Generic Frontend Server that could make it crash if a
1448 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1451 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1452 Must be issued before open, in order to be in effect.
1454 --- 2.0.9-6 2004/01/12 Debian/Windows
1456 Make the SRU server more picky WRT unknown params, etc.
1458 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1460 New YAZ client command, options, that sets Z39.50 options.
1462 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1463 options from a string of tokens (one token for each option bit).
1465 Update SRW diagnostic code messages.
1467 --- 2.0.9-5 2004/01/07 Debian/Windows
1469 Handle user defined stylesheet for SRW/SRU.
1471 --- 2.0.9-4 2004/01/06 Debian/Windows
1473 Fix bug in decoding of Content-Length.
1475 --- 2.0.9-3 2004/01/06 Debian/Windows
1477 Fix a bug with decoding of XML packed records.
1479 --- 2.0.9-2 2004/01/05 Debian only
1481 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1483 Fix bug in SRW/SRU diagnostics decoding.
1485 --- 2.0.9 2004/01/05
1487 Fixed bug in Generic Frontend Server which could drop records exceeding
1488 preferred message size. Reported and fixed by Irina Dijour.
1490 Fixed calculation of package size for structured records in Generic
1491 Frontend Server. Reported and fixed by Irina Dijour.
1493 Fixed namespace for SRW/SRU diagnostics.
1495 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1497 --- 2.0.8 2003/12/22
1499 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1500 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1503 CQL changes to reflect recent changes to the specification:
1504 * Documentation talks about context sets instead of index sets.
1505 * Documentation talks about indexes instead of qualifiers.
1506 * The CQL-to-PQF transformer's configuration file now uses
1507 "index.set.name = <attributes>" instead of the old form
1508 "qualifier.set.name = <attributes>". (Both forms are still
1509 understood but the latter is deprecated.)
1510 * CQL terms with no explicit index specified are now interpreted as
1511 cql.serverChoice instead of srw.serverChoice (which of course
1512 behaves exactly the same.)
1514 --- 2.0.7 2003/12/16
1516 MARC conversion can now generate ISO2709 output in another
1517 character set. yaz-marcdump uses this facility if you invoke it
1520 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1521 functions from there can be used from C++.
1523 --- 2.0.6 2003/12/04
1525 Frontend server now transfers memory from decoded packages to stream
1528 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1529 references to show up.
1531 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1532 the ZOOM Abstract API. The older names for the same options are still
1533 also supported for the benefit of old applications.
1535 ZOOM-C supports "implementationId" and "implementationVersion" options
1536 to go along with "implementationName". These allow the user code to
1537 specify identification strings to be sent to servers.
1538 Add OID for the new ExtLite attribute set.
1540 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1541 as requested/supplid by Ere Maijala <ere@atp.fi>
1543 For generic frontend server, reverse the order of
1544 "toolkit-supplied / application-supplied" strings sent as implementationId,
1545 Name and Version. Also, remove the spaces around the slash. This brings
1546 the GFS in line with the behaviour of ZOOM-C on the client side.
1548 Add function ZOOM_scanset_display_term.
1550 yaz-client shows scan displayTerm if present.
1552 Utility yaz-iconv is now installed by default along with the man page
1555 Extend configure check for OpenSSL to use pkg-config where available (such
1558 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1559 server to specify uid/gid/mask for socket using the format
1560 unix:[user=uid,][group=gid,][umask=mask,]file=path
1561 If file= is omitted the existing format is assumed, e.g.
1563 in which case the mask is 0666 (rw for everybody).
1565 Major restructure of YAZ source. All source in libyaz is in src directory.
1566 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1567 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1569 Added man page for utility yaz-marcdump (used to be called marcdump).
1570 yaz-marcdump is installed by 'make install'.
1572 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1573 of incoming package failed.
1575 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1577 Change prototype of odr_perror: add const to message string.
1579 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1581 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1582 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1583 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1584 DNS lookup. There should not be any compatibility problems with this
1585 assuming that blocking=1 or 0 is used.
1587 Fix bad reference in UNIX comstack in function cs_addrstr.
1589 Fix for compilation on AIX.
1591 The generic front-end server (server/seshigh.c) now supports returning
1592 Init diagnostics to the client in User-information-field, in
1593 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1596 --- 2.0.4 2003/09/04
1598 Allow any CQL relation (not just all,any,exact,scr).
1600 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1601 that features the same UI.
1603 Implemented command update0 in YAZ client which is equivalent to
1604 update but uses old of Ext Update ASN.1.
1606 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1607 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1608 Previously no OID was used for this info.
1610 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1611 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1612 returns 'malformed search term' otherwise.
1614 SortResponse member resultCount now set to NULL in sort handler of
1617 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1620 Add three new utility functions for translating OIDs between various
1621 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1622 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1623 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1624 char *oid_to_dotstring(const int *oid, char *oidbuf);
1625 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1627 Reverted modifications for ES Update definition for z_IU0Update
1628 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1629 is back to YAZ 2.0.2.
1631 String value attributes for CCL parser.
1633 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1634 which their FirstSearch server returns in Init responses, sometimes
1635 carrying useful diagnostic information when Init fails. This has the
1636 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1637 "z39.50/oclcui.asn", where its definition is somewhat different from
1638 what OCLC document on their web-site, as required to interoperate with
1641 Support for anonymous authentication in yaz-client. Use the command
1644 * Fix the OID of the Index Data-local "admin" Extended Service from
1645 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1646 the 1000, which indicates a locally-defined OID, was a mistake.
1648 --- 2.0.3 2003/06/20
1650 Fix CCL directive @case handling so that it affects string match for
1651 both CCL keywords and qualifiers.
1653 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1654 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1655 Decoder has been updated with ASN.1 changes as listed in
1656 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1657 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1658 z_IUUpdate, remains unchanged.
1660 ZOOM_record_get may now return a record in a specific character set.
1661 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1662 "from" is the character set of record as returned by target. "to" is
1663 the character set to be returned. If omitted, "to" is UTF-8.
1665 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1667 New ODR utility, odr_getelement, which returns name of element for
1668 which encoding/decoding failed.
1670 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1671 in cases where a required element was omitted.
1673 Bug fix: some MARC8 sequences were not converted.
1675 New ZOOM option "step" which specifies number of records to be
1676 retrieved in one chunk. Used in conjunction with "start" and "count".
1678 SRW support for yaz-client. Use scheme http: to use it, e.g.
1681 yaz-client no longer does (un)intelligent character set conversions
1682 by default. Can be enabled with charset and marc_charset commands.
1684 xmalloc trace fix for 64-bit systems such as DEC alpha.
1686 Solaris 2.6 compile fix.
1688 New function, cql_strerror() translates SRW error codes, as returned
1689 by cql_transform_error(), into human-readable English strings. Used
1690 in yaz-client diagnostics when appropriate.
1692 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1693 converts it into a type-1 query which is sent to the server. This
1694 makes CQL available for use with all Z-servers, as opposed to the tiny
1695 minority that can handle CQL queries themselves.
1697 --- 2.0.2 2003/04/28
1699 New Debian package layout similar to the Redhat Package layout.
1701 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1702 and search result respectively.
1704 --- 2.0.1 2003/04/25
1706 Redhat package is now several packages: libyaz (runtime libraries),
1707 libyaz-devel (development and documentation, and yaz (utility programs).
1708 Package spec file by Morten Bogeskov.
1710 New member 'schema' in struct bend_fetch_rr which the name of requested
1711 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1712 handler MAY set this to reflect the schema of the returned record.
1714 New member 'display_term' in struct scan_entry. GFS now sets member entries
1715 and allocates scan entries to be filled by user scan handler. In previous
1716 version, entries member was allocated by the scan handler. That still works,
1717 but the GFS will ignore member display_term - assuming it was NOT set by
1718 the handler. The fact that the GFS now allocates the entries both allows
1719 for new members and makes a scan handler easier to write.
1721 Fix CQL lex buffer overflow.
1723 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1724 SRU default recordPacking is string.
1726 SRU protocol support for frontend server.
1728 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1730 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1732 Added scan for the ZOOM shell (zoomsh).
1736 * String Identifers for Schemas (Amendment 5).
1737 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1738 Old definition for schema
1739 Odr_oid *schema; /* OPT */
1744 Z_InternationalString *uri;
1745 #define Z_Schema_oid 1
1746 #define Z_Schema_uri 2
1749 * resultCount parameter to Sort Response (Amendment 1).
1750 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1752 Support for SRW 1.0 over HTTP. This is an optional feature and
1753 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1756 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1757 on the same port. SRW SearchRetrieveRequests are mapped
1758 to bend_init,bend_search,bend_fetch,bend_close.
1760 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1762 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1763 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1765 ZOOM connections are SRW based if schem http is used for hostname
1766 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1767 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1769 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1770 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1771 distance=n, order=true/false, relation=le, prox unit=word. If
1772 n is omitted, distance 1 is used.
1774 Fixed problem with C compiler include path in wrong order.
1776 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1777 on Solaris. Patch from Ko van der Sloot.
1779 New MARC decode API. All new functions operate on a yaz_marc_t
1780 handle. The most important new functions are: yaz_marc_create,
1781 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1782 decode and destroy respectively. Decoder can produce formats
1783 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1784 include/yaz/marcdisp.h.
1786 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1787 to UTF-8, UCS-32, wchar_t or Latin-1.
1789 * Prototypes for yaz_iconv_-functions moved to separate header
1790 include/yaz/yaz-iconv.h.
1792 Make a few private functions 'static' in unix.c. This prevents
1793 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1795 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1796 are set when Init Response is received.
1798 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1799 but returns diagnostic set as well.
1801 New function yaz_strerror which is a portable wrapper for
1802 strerror/strerror_r/GetLastMessage.
1804 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1805 is returned for MARC. If type is "oai", then OAI MARC is returned.
1807 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1810 --- 1.9.2 2002/11/26
1812 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1814 Fix bad race conditions on SIGTERM and terminate gracefully in
1817 Move retrieval (data1) module to Zebra since nobody seems to be
1820 Add GRS-1 render for ZOOM using same format as yaz-client.
1822 --- 1.9.1 2002/10/05
1824 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1826 Fix broken ESpec handling in data1 module.
1828 SGML reader parses comments and makes them part of the data1 tree.
1830 Added several type casts so that YAZ compiles as C++ code.
1832 ZOOM didn't handle PDU encoding failures properly.
1834 Added more Bib-1 diagnostics (approved extensions).
1836 GNU configure: better check for iconv.
1838 More portable use of accept, getpeername. Check for socklen_t. Use
1839 int/size_t if socklen_t is not defined.
1843 PQF parser rejects bad queries - including those with extra
1844 characters in them. PQF parser used to silently ignore that.
1845 Cleaner API for PQF added, which allows you to get detailed
1846 error information for bad queries (see yaz/pquery.h).
1848 Fixed bug in ZOOM_record_get for type "database".
1850 Implemented mini iconv library supporting conversions between
1851 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1853 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1855 --- 1.8.9 2002/08/20
1857 Fixed ZOOM C record cache so that preferredRecordSyntax and
1858 elementSetName is used to check for already fetched records.
1860 --- 1.8.8 2002/08/02
1862 Added three members in bend_initrequest structure to facilitate
1863 character set negotiation.
1865 Fixed a bug in frontend server that could cause indefinite
1866 loops under rare conditions.
1868 Revised character set utilities (charneg.h) so that encoding
1869 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1871 For PQF, directive @term <type> sets term type for Scan/Search.
1872 Here <type> is general, string, numeric, null. The term type
1873 is inherited - just like @attr.
1875 New call odr_set_charset that sets character set conversion for
1876 international-strings on a ODR stream. Prototype is:
1877 int odr_set_charset(ODR o, const char *to, const char *from);
1878 The InternationalString is still represented as C string in YAZ
1879 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1880 won't). On the protocol level, you can use any encoding.
1882 Support for UNIX sockets in ZOOM.
1884 Solaris recv sometimes returns errno == ENOENT. It is treated as
1885 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1887 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1888 both client and server. Code by Morten Bogeskov.
1890 --- 1.8.7 2002/05/22
1892 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1893 that they can be used directly from Visual Basic. You must recompile
1894 your windows APP if you're using ZOOM.
1896 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1897 Commands "lang" and "charset" sets language and character set respectively.
1898 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1899 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1901 Attributes from multiple CCL fields may be OR'ed rather than merged
1902 using directive "@field or". Fields are still merged by default -
1903 equivalent to "@field merge".
1905 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1908 Fixed bug in zget for parameter ExtendedServicesResponse.
1912 --- 1.8.6 2002/03/25
1914 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1916 Client displays USR.1:SearchResult-1 (hits per term).
1918 Additional Search Info for search in Generic Frontend Server.
1920 Fixed CCL parsing of "field=s".
1922 WIN32 installer - using the excellent NSIS software from nullsoft.
1924 Fixed CCL parsing of "field = - <number>".
1926 Added function yaz_marc_decode that decodes MARC for line mode
1927 display or XML (similar to that used by JZKit).
1929 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1930 Z39.50. But ISO/ILL was, however.
1932 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1933 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1936 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1938 --- 1.8.5 2002/02/03
1940 New YAZ client features: Command completion and new commands:
1941 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1942 Code provided by Jacob Poulsen.
1944 New call oid_trav, that visits all registered OIDs via callback.
1946 Function ZOOM_record_get now returns const char pointer rather than
1947 void pointer. It saves a lot of type casts.
1949 For YAZ client, command "auth" now allows you to set authentication
1950 in IdPass style. It is enabled when three tokens are given - order
1951 is user, group and password.
1953 Fix memory leaks in MARC record handling for ZOOM.
1955 New option for YAZ client, -k <kilobytes> that sets
1956 maximum record size. Similar to -k option for generic frontend
1957 server and yaz-ztest.
1959 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1961 Prefix query parser reports "fail" when bad attribute set is given.
1963 Fix in MARC decoder. Proximity logging. Fix for attribute set
1964 in scan handler for server. Patches by Shigeru Ishida.
1966 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1969 Configure option --with-openssl=<dir> now works when a directory is
1970 specified. Patch provided by Morten Bogeskov.
1972 New option for YAZ client, -u <auth>, that sets authentication.
1974 ZOOM fix: error information was sometimes "missing", since error
1975 was cleared/reset too when it shouldn't.
1977 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1979 --- 1.8.4 2002/01/04
1981 Scan for ZOOM API. New object ZOOM_scanset. New functions
1982 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1983 ZOOM_scanset_destroy.
1985 New ZOOM function, ZOOM_connection_last_event, that returns type
1986 of last event (such as "receive data", "send data", "apdu received",
1989 New ZOOM option, schema, that specifies schema for retrieval.
1991 New CCL feature. Qualifiers can be aliases for one or more
1992 other qualifiers (if more than one is given, OR is used).
1994 ZOOM uses named result sets if target supports it.
1996 Two new YAZ client commands: . (dot, which sources a script of YAZ
1997 client commands), and ! (to execute shell command.). Implemented
2000 Working on Debian packages.
2002 --- 1.8.3 2001/11/19
2004 YAZ client enables named result sets only if target supports it.
2006 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2008 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2009 with key="host" to get same result.
2011 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2012 Function Z3950_resultset_record(s) returns references to records
2013 "owned" by resultset. To become owner use Z3950_record_clone.
2015 Function z_ext_record handles Extended Services. Thanks to
2018 --- 1.8.2 2001/11/12
2020 CCL Parser fix: ignore token comma when dealing with and-lists.
2022 Documentation updates for COMSTACK.
2024 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2025 Changed prototype Z3950_records. For some functions, int parameters
2026 were changed to size_t.
2028 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2031 New MARC decode/display function, marc_display_exl, which properly rejects
2032 non-ISO2709 records. YAZ client uses it.
2034 --- 1.8.1 2001/10/29
2036 Fix bug: local attribute set wasn't set correctly in PQF strings.
2040 * Old Z39.50 codecs no longer supported.
2042 Added ZOOM C binding. See http://zoom.z3950.org/
2044 Renamed states for COMSTACKs to avoid confusion with events.
2046 Implemented cs_look and proper cs_rcvconnect.
2048 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2050 Configure detects POSIX threads on OpenBSD.
2052 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2053 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2055 When error is returned from present handler, non-surrogate diagnostic
2056 is returned in present response (and fetch handler is no longer called).
2058 * Minor adjustments to pquery parser (PQF). Token characters may be
2059 escaped by using backslash (C-style).
2061 PQF parser allows string attribute values to be specified. For @attr,
2062 non-numeric characters after the equal-sign are treated as strings
2063 (e.g. @attr 9=title).
2065 CCL trunction character may be defined (@truncation in file)
2067 * function zget_ExtendedServicesRequest sets waitAction to
2068 waitIfPossible (was wait).
2070 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2073 CCL operator names may be set in field definition files (CCL_bibset).
2074 See ccl/bib1 for an example.
2076 Fixes in ASN.1 compiler for C++ compatibility.
2078 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2079 and "op_or" to avoid conflict with C++.
2081 Fixed problem with GNU readline detection on Redhat 7.0.
2083 Added step-size for Scan backend handler.
2085 Fixed bug that made the frontend server crash when no attribute
2086 set was specified for scan.
2088 Front-end server automatically switches to original working directory
2089 when installed as an NT service. Previously -w had to be specified to
2092 Added extended attributes for retrieval module (data1), so that data1
2093 records carry d1_readXML/SGML attributes. d1_read also supports
2094 null-data rules ( <tag/>)
2096 On UNIX when POSIX threads are available, a separate library libyazthread
2097 is created. Programmers should link with that library and the yaz library
2098 when using threads. The reason for the split was that some applications
2099 on Linux, such as Apache, doesn't work well when using shared objects that
2102 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2103 (or any frontend server) in SSL mode by specifying ssl: followed by
2104 address. Only tested on UNIX.
2106 Added feature for CCL module. Virtual structure s=al or s=ol generates
2107 and-list and or-list respectively instead of phrase search.
2111 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2112 log_mask_str. This was done to avoid name conflicts with other libraries
2113 (such as other PHP extensions).
2115 Added raw OID member for preferred record syntax (request_format_raw)
2116 and returned record syntax (output_format_raw) for backend fetch method.
2118 Config file yaz-config now accepts options so that it returns specific
2119 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2121 Shared library support for UNIX using GNU libtool.
2123 * Modified backend interface. Request/Response struct's replaced by
2124 one read/write C struct. For example bend_fetchrequest and
2125 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2126 Every handler - even search has to be registered in bend_init
2127 handler. This means that the YAZ library no longer refers to
2128 external functions and it makes it possible to make the whole
2129 thing a single DLL/SO.
2131 Added Segment handler for backend server.
2133 Added Zmbol/Zebra administrative functions to YAZ client.
2135 Threaded frontend server on UNIX (when POSIX Threads are available).
2136 Starting the server with option -T enables multi-threading.
2140 Added configure option --enable-comp/disable-comp to control use
2141 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2142 located in sub directory asn.
2144 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2145 in ${exec_prefix}/bin along with the other programs yaz-client and
2148 GNU automake used to maintain makefiles.
2150 Added several OID's.
2152 Changed retrieval module so that we can load records with no abstract
2153 syntax defined. Tagpaths in these records are fully composed of string
2156 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2160 On UNIX, the generated makefile now supports a proper 'make install'.
2161 The prefix can be set via GNU configure to set the install location
2162 (default is /usr/local).
2164 * YAZ programs client and ztest were renamed to yaz-client and
2165 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2166 locations, such as /usr/bin,/usr/local/bin,etc.
2168 * YAZ Header files were moved from include to include/yaz. YAZ Header
2169 files are referred to as include <yaz/log.h> rather than <log.h>.
2170 The YAZ include path (-I ..) is therefore the same as before. Programmers
2171 should update their #include statements or use -Ipath/include/yaz
2172 instead. The main motivation for doing this change is that YAZ header files
2173 can be installed in "standard" locations /usr/include,/usr/local/include
2174 without introducing conflicts, since ALL YAZ header files are stored
2175 in subdirectory yaz (under /usr/include for example).
2177 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2178 rather than project/workspace files. We switched because project files
2179 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2182 Changed name of logging function, logf, to yaz_log, to prevent name
2183 clash with some math-log functions. The YAZ header log.h defines logf
2184 to yaz_log (#define) so there should be no incompatibilities by this
2187 Added bend_start/bend_stop handlers for server. These handler are
2188 called on start/stop of server. For windows they are called whenever
2189 a service is started/stopped.
2191 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2192 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2193 in util/yc.tcl. The auto-generated C code structures are, in a few
2194 cases, incompatible with the old decoders. There are differences in the
2195 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2196 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2197 The preprocessor variable ASN_COMPILED is defined when the compiled
2198 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2199 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2200 wish to use the old encoders/decoders you can specify --disable-yc
2203 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2204 version so that it supports both new - and old version of DB Update
2206 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2207 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2208 change. The name parameter can be set to 0 in which no name is specified
2209 for the construction. The macros odr_implicit and odr_explicit sets name
2210 parameter to zero for the construction involved. New macros
2211 odr_implicit_tag and odr_explicit_tag are similar to the others,
2212 except that a name parameter is added. For programmers' that don't use
2213 ODR they probably only need to change the call to z_APDU and z_External.
2215 Added access control facility by interfacing the TCP wrapper library.
2216 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2217 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2218 name of the daemon and enables the access control as specified in
2219 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2221 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2222 den Dool <H.M.vdnDool@kub.nl>.
2224 Added reference ID parameter to most functions in server API - refer
2225 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2227 Changed name of ccl library to libccl.a (was ccl.a).
2229 Fixed bug in decoder for Explain (Category TargetInfo).
2231 Added support for GNU readline in client. Thanks to Jacob Poulsen
2232 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2234 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2235 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2236 IMPLEMENTATION! This change was made to the development version before
2237 the ZIG decided to retract the amendment. If any users MUST be
2238 compatible with the original Update definition, PLEASE CONTACT US, and
2239 we will include a separate definition corresponding to the old Update
2240 ES. Note that because of the change to the ASN.1 of the
2241 TaskPackageRecordStructure we cannot define a single structure that
2242 will support both versions.
2244 * Added const modifier to buffer parameter for some ODR/BER encoding
2245 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2246 completeWAIS, odr_dumpBER.
2248 Fixed bug in client.c which caused a crash when a scanResponse didn't
2249 contain positionOfTerm.
2251 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2252 * will cause an error in a client if a non-YAZ target sends both a
2253 * list of Scan entries and non-surrogate diagnostics.
2255 Retrieval module enhancements. Tag sets may be typed in the reference
2256 to it. From the .abs-file the "tagset" directive takes a third optional
2257 integer type for the tag set referenced. From a .tag-file the "include"
2258 directive takes a third optional type as well. The old "type" directive
2259 in the tag set itself is still recognized but acts as the default type
2262 Backend interface change. Individual Scan terms returned from bend_scan
2263 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2264 in include/backend.h.
2266 Retrieval module enhancements. Multiple tag sets and attribute sets may
2267 be specified in abstract syntax specs. Revised the error/warning for
2268 logging messages reported by the retrieval module when reading the
2271 Object Identifier system (oid_..) changed. The API is backwards
2272 compatible but the oid-routines now allocates new OID's when needed.
2273 Raw OID's may be specified in oid_getvalbyname.
2275 YAZ now uses GNU configure to generate Makefile(s).
2277 * Minor changes in some of the member names of DeleteResultSetRequest and
2278 DeleteResultSetResponse. See include/proto.h.
2280 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2281 and added member 'languages' in TargetInfo (which was missing).
2283 Changed the way attribute sets are handled in the retrieval
2284 module. These are now cached, just like the abstract syntaxes
2287 Changed YAZ so that it links with compiled ASN.1.
2289 Added Explain-schema definitions and mapping routines. The following
2290 Explain categories have been implemented: AttributeDetails,
2291 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2293 Fixed minor bug in Windows version of Server Library.
2295 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2297 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2299 Added EXTERNAL: UNIverse Resource Report (non-standard).
2301 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2302 ENUMERATED and SET OF.
2304 * Added 'const' to some of the char pointer arguments for the
2305 functions, data1_read_node, data1_getelementbytagname,
2306 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2309 Fixed bug in data1_insert_taggeddata - the last_child member of
2310 parent wasn't initialised.
2312 * Changed data1_read_record and data1_read_node so that the supplied
2313 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2314 doesn't refer to any parts of the "SGML"-buffer.
2316 Fixed bug in server library (Windows version of statserv_remove).
2318 * Changed code so that it compiles as C++. The type definition
2319 of Odr_fun which is a member of Odr_arm was changed. The result is,
2320 that an explicit typecast is needed for the fun pointer when
2321 using Odr_arm - as in:
2322 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2324 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2326 Implemented the new structured date and time definition as approved
2327 by the ZIG. Added schemaId element to the specificTag in Espec-1
2328 (also approved at the last ZIG). Thanks to RVDM.
2330 Added some Object identifiers (RVDM).
2332 Changed the Update Extended Service (RVDM).
2334 Added command "refid" to client which specifies referenceId for
2335 the following requests.
2337 Implemented extended service handling for server. See ztest.c
2338 for an example as well as backend.h. New handlers are registerd
2339 in the Init handler.
2341 * Changed interface for sort in server.
2343 Added new members to statserv_options_block. It allows a server
2344 to read options from another source than just the command line. Thanks
2345 to Charles Woodfield.
2347 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2348 renamed to zboolean. Some C++ compilers complained about the name.
2350 Minor changes to gils.abs. Added index 's' (sort) on title
2351 and date/time-last-modified.
2353 --- 1.4pl2 1998/1/30
2355 Fixed bug in server library regarding inetd mode (-i). This bug
2356 was introduced by release 1.4.
2358 --- 1.4pl1 1998/1/29
2360 Added sort facility in client and backend server interface.
2362 Fixed problem with dependencies in Makefile(s).
2364 Fixed bugs for encoders/decoders of extended services and
2367 Implemented sub-tree feature for schemas. Sub-trees are
2368 referenced in *.abs-files. See explain.abs for an example
2369 of the use of this feature.
2371 Modified bib1.att; local attributes for ANY didn't include
2372 ANY itself (only affects use of the retrieval module).
2374 Fixed bug in plain SGML reader in function data1_read_node:
2375 tags with prefix "var" was incorrectly interpreted as variants.
2377 Added feature "sub-schemas" to enable references to - and definitions
2378 of - group of elements.
2380 * Removed member parent from type data1_element (in data1.h).
2382 Implemented function odr_nullval() that returns the value of
2385 * Removed member num_children from data1_node (in data1.h).
2387 Made NT service interface part of the server library. The
2388 function statserv_main uses the NT service when required and
2389 calls the statserv_start / statserv_close routines.
2391 Routine zget_SearchRequest and zget_PresentRequest fills
2392 resultSetName/Id member with "default" instead of "Default".
2394 Fixed memory leak in server. Request queue member wasn't freed.
2396 Fixed nmem_exit so that memory is freed.
2400 Revised the CCL parser utility to be thread safe.
2402 Added function, oid_ent_to_oid, to replace the function
2403 oid_getoidbyent, which is not thread safe.
2405 * Added nmem_init and nmem_exit to initialize and release
2406 NMEM resources. Function nmem_init should be called once in the
2407 initial thread before NMEM/ODR is used. statserv.c and client.c
2408 have been changed accordingly. The change was necessary to make
2409 NMEM thread safe. The NMEM memory pool is shared amongst threads
2410 in a process. Unix-based applications will still work fine without
2413 Added NT Services interface for the the Z39.50 (statserv) Server.
2414 Refer to the ztest.c source on the usage.
2416 Windows 95/NT port using MSVC5.0. Project files are included in the
2419 * Defined new 'global' handle for the retrieval (data1) system. The
2420 new handled, data1_handle, describes the state of the data1 system.
2421 This handle is passed as first argument to virtually all
2422 data1 related routines. The functions data1_create and data1_destroy
2423 creates and destroys a data1 handle respectively.
2425 Added ODR encode stream member to all backend request structures
2426 init, search, scan etc. This stream should be used to allocate all
2427 memory used for the response when thread safe operation is needed.
2429 Changed the comstack utility, cs_addstr, to be thread safe. The
2430 returned hostname string returned by the function is now part the
2433 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2434 function. The cs_straddr takes a COMSTACK handle as argument, so this
2435 function must be used after cs_create and before bind/connect.
2436 This function is thread safe.
2438 Moved test server to 'ztest' directory - generic server code still
2439 in 'server' directory.
2441 Made prefix query (pquery.c) utility thread safe.
2443 Added new function modifier YAZ_EXPORT to 'export' public DLL
2444 functions when using windows (see include/yconfig.h).
2446 Added definitions to the OID database (util/oid.c) (RVDM).
2448 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2450 Added call to ccl_rpn_delete in client program.
2452 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2453 release of RPN structure.
2455 Added support for C++, headers uses extern "C" for public definitions.
2456 With input from RVDM.
2458 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2459 Thanks to Ronald van der Meer (RVDM).
2461 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2463 Added support for private extensions to the OID database
2464 (oid_setprivateoids()). Thanks to RVDM.
2466 Added optional, physical ANY (key replication)
2468 Fixed null-reference problem in GRS-1 output filter.
2470 Proximity operator added to Prefix Query Format (PQF).
2472 In test client command "base" accepts multiple databases.
2474 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2478 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2480 Smallish bug-fixes in the new encoders/decoders (explain).
2482 Bug fixed in DeleteRequest.
2484 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2486 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2488 Added SOIF syntax (using private OID for now) to retrieval module and client.
2490 Added Update extended service.
2492 Added SearchResult-1 additional info structure.
2494 Added optional CCL (ISO8777) interpreter as separate module. Available
2497 --- 1.2 1996/6/10 (1st anniversary release)
2499 Added Summary record syntax. Lightly tested.
2501 Added OPAC record syntax. Untested.
2503 Added ResourceReport service encoders/decoders. Untested.
2505 Fixed bug in z_Unit - wrong tagging on unitSystem.
2507 Fixed bug in the DiagRecs decoder.
2509 Added options for max PDU size and session timeout to frontend-server.
2511 Added documentation of query-language parsers and other supporting utilities.
2513 [frontend-server] Added Attribute set to the bend_scanrequest API.
2515 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2516 surrogate diagnostics were generated.
2518 [retrieval] Allow multiple local values for attribute.
2520 [retrieval] Allow multiple attributes per element in .abs files. index type.
2522 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2524 --- 1.1pl2 1996/4/10
2526 Minor changes, mostly specific to Zebra's requirements (retrieval)
2530 Repaired bug in frontend server when running multiple listening
2531 endpoints in dynamic mode.
2533 z_External() now won't break if a known, ASN.1 value comes encapsulated
2534 in an octet-string. The value will pass through unmodified in an Odr_oct.
2536 Added a bit of code to the demo client to decode & display
2537 ASN.1-structured records represented in the octet-aligned branch of
2538 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2540 Added z_ext_getentbyref() to the ASN module. Doc updated.
2542 * Completed the SCAN definition in the ASN module. This may break SCAN
2543 code based on older YAZ-versions at compile-time. The fix is easy -
2546 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2547 under the SCAN definition. Remember to initialize this, server-people.
2549 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2550 that this does not extend to ODR and ASN.
2552 Comstack allows insertion of established socket (primarily for
2553 inetd-operation of servers). Doc updated.
2555 Front-end server can now start from the inetd in TCP mode. Doc
2558 --- 1.0pl4 1996/1/24
2562 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2563 the rank and record number.
2565 Adjustments to the frontend server.
2567 Fixed diagnostic BER dumper. It ignored the file argument.
2571 Various changes to retrieval module.
2573 Changed the union discriminators of the protocol files from enums to
2574 ints paired with #defines.
2576 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2579 *Changed operator in the RPN structure to 'roperator', again to avoid a
2582 Fixed problems in Explain decoders/encoders.
2584 --- 1.0pl2 1995/12/6
2586 Memory bug in log module fixed.
2588 --- 1.0pl1 1995/12/5
2590 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2592 Bug in Explain DatabaseInfo module fixed.
2594 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2598 The shift to v1.0 signals that we now consider the *core* functionality
2599 of YAZ reasonably stable (the core being more or less equivalent to
2600 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2601 tested (Explain not at all - though that will happen soonish).
2603 Minor changes to code to support Windows port.
2605 Various minor changes after we're getting to use GRS-1 & co. more.
2607 Added Espec-1 format.
2609 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2610 of the protocol and it cannot be selected when encoding (maps into 'string'
2611 when decoding). Needed to talk to some servers.
2613 Demo client can request simple element set names.
2615 Added Diagnostic Format encoders/decoders.
2617 Added simple Close handling to frontend server (no hooks for resource
2618 reporting yet), and demonstration client.
2620 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2622 --- 1.0b3 1995/08/24
2624 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2625 handled incorrectly when records were requested in the searchResponse. This
2626 will only affect you if you use the frontend-server.
2628 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2629 Test-client will ask for and print GRS1. Ztest will return dummy records
2632 Added Explain encoders/decoders to the service-level API. Untested.
2634 Added Extended Services: Item Order encoders and decoders to the Service-
2635 level API. Untested. We could use a recent copy of the pertinent bits
2636 of the ILL protocol to add those bits.
2638 Added diagnostic format 1 encoders/decoders to the service-level API.
2641 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2642 odr_cons.c, which causes a more correct output.
2644 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2645 was always set to 0 when no records were requested in the searchRequest.
2647 * Added better external-handling. This shouldn't harm old code that
2648 *encodes* externals. It can break code that looks for a
2649 'single-ASN1-type' representation, since those types that are known
2650 are now decoded immediately. Look at the SUTRS sample code in
2651 seshigh.c and client.c. Documentation updated.
2653 Handling of structured records in bend_fetchresponse. Length -1 marks
2654 structured record, type is deduced from format field.
2656 --- 1.0b2 1995/06/27
2657 Fairly quick maintenance release to add SUTRS support.
2659 Fixed handling of SUTRS records in the demonstration client.
2661 * Added format field to the bend_fetchrequest and bend_fetchresponce
2662 structures of the backend API (frontend server). When the record is
2663 returned, the value of the format field is mapped to an OID. The
2664 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2665 of the record. The special value VAL_NONE in the bend_request means
2666 that no specific format was requested by the client. Documentation
2667 updated accordingly. Test server (ztest) will return a fixed dummy
2668 SUTRS record if your client requests SUTRS.
2670 Documentation updated accordingly.
2672 You can now set external libraries and RANLIB support in the top-level
2676 First public release.
