1 ZOOM_record_get supports new parameter "format" which makes it format
6 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
7 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
9 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
10 POSIX/Unix builds .so with major version 4.
12 Remove old LOG_-defines from log.h. They have been obsolete and
13 undefined by default for the last 5 years.
15 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
17 GFS: Remove socket (int *fd) from search_rr handler. The socket
18 descriptor ptr is a facility that allowed a search handler to supply
19 a socket which would serve as a callback - when search was complete.
20 This facility has now been in use for years.
22 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
23 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
24 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
25 returns 'const char *' rather than 'char *. The returned string is
26 read-only and should not be modified by applications. COMSTACK cs_close is
27 now a void function - it no longer returns int. No applications check for
28 the value and the implementations has always returned 0.
30 ZOOM: use size_t for scan hit counts and str size. Functions
31 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
32 occ (hit count) and len (string length) are now of type size_t pointer
33 rather than int pointer. This is to be able to represent large hit counts
34 and to also just to use the proper type for string length (strlen result).
36 New JSON parser. Refer to include/yaz/json.h .
38 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
39 Used to be int in some cases. Many wrbuf_-functions used to return an int
40 indicating some length.. These return values were never used. And so they
43 ODR: odr_malloc, odr_total now takes size_t for size.
45 clone_z_type: fix leak; occurred for encoding failures.
49 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
50 bug was introduced in 3.0.51.
54 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
56 tcpip comstack: fix leak for getaddrinfo.
58 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
59 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
60 Decoding of SRU "path" database is performed by private function
61 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
62 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
64 yaz-client: honor base command for SRU. Change when database setting
65 is applied for SRU and ensure it is kept when a connection is reset.
66 Change also the way errors are displayed or SRU (decoding of packages).
70 Add support for extra request / response data for SRU codecs and GFS.
71 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
72 for extra data response buffer and length. For the GFS, both request
73 and response data (XML) is carried in extra_args and extra_response_data
74 for the search handler. Patch by Ko van der Sloot.
76 ZOOM: For queries that cannot be converted to the specified rpnCharset,
77 ZOOM now returns a diagnostic on the client-side ('invalid query' /
78 10010). This fixes bug #2113.
80 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
81 cmdfile included a 'quit' command that would result in a memory violation.
85 Make a number of functions defined in xmlquery.c static. These have
86 never been declared in a public header file (yaz/xmlquery.h) and was
87 made public by mistake.
89 Improve speed of character conversions (iconv utilities). This makes
90 conversions from MARC-8 faster.
92 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
93 unless type desired is "raw". This will prevent type "xml" from
94 returning ISO2709 .. Which obviously can not be XML parsed.
96 Fix memory leak in ZOOM that would occur if option apdulog was used
97 on a re-used connection.
99 Frontend server logs HTTP requests.
101 Frontend server now sends Z39.50 close when it times out (sesssion has
102 been idle for too long). Versions 2.0.30 and earlier also sent close.
103 But due to a mistake this was disabled in all versions after that, i.e.
104 the server would just close the socket immediately.
106 yaz-client emits a better message when receiving an unrecognised
107 userInformationField.
109 Skip zero-length subfields when decoding ISO2709. This rare case happens
110 if a record has two FS characters in a sequence. Without this patch
111 there would be a reference beyond char array in using_code_len fragments
114 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
116 --- 3.0.48 2009/08/28
118 The show command offered by the zoomsh command now takes a 3d optional
119 parameter type which is what is passed to ZOOM_record. If the type
120 argument is omitted, "render" is used.
122 RPN to CQL conv may use USE string attributes (bug #2978).
124 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
126 --- 3.0.47 2009/07/08
128 Function yaz_xml2query allows a diagnostic element in the PQF XML
129 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
130 code and additional info respectively.
132 The BER BOOLEAN is now the integral type Odr_bool which still happens
133 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
134 typedef'd to Odr_int. This is still an integral 'int', but it may be
135 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
136 ASN-1 compiler as well as programs has been updated to use the new types.
138 --- 3.0.46 2009/06/08
140 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
141 only the bibliographic record was rendered. For type=opac, an OPAC
142 record is only returned if it is present.
144 iconv: small fix for encoding of advancegreek.
146 yaz-client: avoid double display of SRU/SRW records (bug #2798).
148 yaz-client: option auto_reconnect=on really reconnects.
150 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
152 server: avoid null ptr ref for for yaz_poll errors.
154 build: fix RPM build for RHEL 5.3.
156 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
158 --- 3.0.45 2009/03/31
160 Fixed bug #2709: TCP connect returns Invalid argument.
162 Fixed compilation for mingw.
164 Honor charset for raw records (ZOOM_record_get).
166 Fixed use of errno for threaded mode that was seen on Solaris 10.
168 Fixed argument passing with blanks in value for Windows Service.
170 Disable YAZ' own log rotate by default (no 1 GB limit).
171 The variable l_max_size which specifies the log file limit is set to 0
172 (DISABLED): This is due to the fact that YAZ is most often deployed using
173 logrotate. Also YAZ can not perform log rotate because of unsufficient
174 permissions (setuid).
176 --- 3.0.44 2009/02/17
178 List supported encodings in man page for yaz-iconv.
180 Fixed missing SSL libs for --libs output
182 Re-established OID record syntax application-xml. Nobody should use it
183 but we don't want to change soname because of this symbol being absent.
185 --- 3.0.42 2009/02/02
187 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
189 Added member named_result_sets for init handler struct for the GFS. This
190 allows a server to disable named result sets.
192 Removed OID record syntax application-xml.
194 Added support for rule-based transliterator for ICU wrapper of YAZ.
196 Fixed bug #1902: yaz-icu XML output.
198 Make YAZ checks Emacs friendly.
200 BITSTRING value shows value. Bug #2346.
202 ISO2709 decoding: skip control characters from indicator data.
204 Omit sort key by default in yaz-icu's output.
206 Allow combined single char options (again) for YAZ' options function.
208 Utility yaz-marcdump got option to display YAZ version (-V).
210 Allow YAZ to use ICU 3.4.
212 Added new ICU test case which illustrates removal of diacritics.
214 --- 3.0.41 2008/12/29
216 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
218 --- 3.0.40 2008/12/29
220 For configure, using option --without-xml2 also disables Libxslt/Libexslt
223 Fixed bug #2352: yaz-marcdump crashes for certain record.
225 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
227 Added support for Danmarc2 to UTF-8 conversion.
229 Added support for ISO5426 to UTF-8 conversion.
231 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
232 implementation version.
234 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
236 --- 3.0.38 2008/11/10
238 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
239 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
241 ZOOM C now interprets databaseName option for ZOOM connection as path
244 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
246 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
248 Dummy Libxml2 types no longer defined in headers of YAZ'.
250 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
253 --- 3.0.36 2008/09/26
255 Various ODR chapter fixes.
257 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
259 Added missing source for Windows compilation, mutex.c.
261 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
263 For SRU connections in ZOOM all records up to "count" are now fetched.
265 Fixed crash in generic frontend server (and yaz-ztest) which occurred
266 in Windows due to bad error handling for Libxml2.
268 Added facility for sending arbitrary records (ASN.1 any) using
269 ZOOM C's Extended service update. Patch by Sam Reynolds.
271 New options for ZOOM C's connection, logapdu which makes ZOOM log
274 --- 3.0.34 2008/06/18
276 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
278 --- 3.0.32 2008/06/12
280 Fixed memory violation that could occur when decoding UTF-8. This bug
281 was only present in 3.0.30 of YAZ.
283 --- 3.0.30 2008/06/06
285 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
286 GNU TLS is used by default (if found).
288 yaz-ztest returns OPAC records if a client asks for OPAC.
290 Improved speed of MARC-8 encoding.
292 Added support for lossy and loss-less MARC-8 encoding.
294 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
296 Added new Windows Service wrapper (sc).
298 yaz-client's itemorder command may now send a file.
300 Fixed yaz-marcdump to allow the use of NS prefix for record element.
302 Added new function yaz_log_xml_errors.
304 Allow (but warn) unknown XML attributes in MARCXML parsing.
306 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
308 The UTF-8 to MARC-8 conversion now uses a different set of characters
309 for Greek symbols. Bug #2120.
311 --- 3.0.26 2008/02/21
313 Added yaz_daemon (daemon.h).
315 Fixed bug #2068: pkg-config trouble
317 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
319 --- 3.0.24 2008/01/28
321 Document --with-xml2 option.
323 Added OPAC XML XSD (etc/opacxml.xsd).
325 Allow glob mask for name attribute in retrieval element for the
326 generic frontend server's retrieval facility.
328 Changed yaz_poll_poll to return yaz_poll_except for all returned events
329 except POLLIN/POLLOUT.
331 Fixed error handling in cs_listen. Bug #2037.
333 --- 3.0.22 2008/01/20
335 Fixed version in yaz/yaz-version.h.
337 Fixed bug #2027: Crash when closing connection.
339 Changed configure so that ICU support is only enabled if only ICU
340 and Libxml2 is available (because the ICU chain is XML based).
342 --- 3.0.20 2008/01/15
344 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
345 is built. Only this DLL depends on the ICU runtime.
347 yaz-ziffy is no longer part of YAZ. It is distributed separately by
348 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
350 Changed license of CCL module to 'Revised BSD'. After consultation with
351 remaining members of the original EUROPAGATE consortium, we are re-issuing
352 the CCL module without a separate license. The software was developed by
353 Index Data as part of a research project. The special license was included
354 to help feed usage information back to the project consortium to support
355 project evaluation. At this time, the project consortium has long-since
356 disbanded, and the majority of the original principals have retired. At the
357 same time, we have significantly modified the software during the following
358 years, to the point where very practically no original code remains. To
359 simplify re-use of the software, we have contacted those members of the
360 consortium who could be reached, and agreed to re-issue the module as a
361 proper part of the YAZ package.
363 Tcl scripts uses /usr/bin/tclsh as preferred shell.
365 CQL closer to being version 1.2 compliant. CQL also allows free-form
366 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
369 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
370 bug could make Extended services handling crash in the ZOOM layer. This
371 bug was only present in YAZ 3.0.18.
373 --- 3.0.18 2007/12/19
375 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
378 yaz-marcdump reads and writes collection wrapped records.
380 Handle OPAC for record conversion module.
382 Fixes for ICU wrapper.
384 Allow ICU libs to be controlled with --with-icu .
386 --- 3.0.16 2007/11/12
388 Added yaz_poll which is a wrapper for select/poll. When poll is available
389 and non-buggy, it is used, by yaz_poll . This allows more than 1024
390 sockets to be in use.
392 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
393 functionality through an XML based configuration (ICU chain). This system
394 is useful for search facilities such as Pazpar2 and Zebra that needs to
395 perform tokenization of indexed material. The ICU code in a separate
396 library libyaz3_icu.a.
398 Added HTTP tunnel facility for COMSTACK, bug #1752.
399 This is a facility that allows a Web proxy, such as squid, to tunnel
400 Z39.50 traffic. This facility is "transparent" to must applications
401 using YAZ. It's enabled by using pseudo transport connect: followed by
402 the proxy address, followed by command, then follwed by he regular
403 "virtual" addresss. For example,
404 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
406 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
408 --- 3.0.14 2007/09/21
410 Fixed bad memory reference in ZOOM_record - cuased by member not being
411 initialized. This was a problem only in YAZ 3.0.12.
413 Fixed bug in conversion from MARC to XML: Non-XML characters in control
414 fields were not removed.
416 Changed the way C code is generated from codetables.xml. Made a MARC-8
417 conversion trie for each characterSet section rather than codeTable.
418 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
419 of codetables.xml from Larry Dixson, LOC. Bug #1464.
421 --- 3.0.12 2007/09/12
423 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
424 from ZOOM_record_error).
426 ZOOM C function ZOOM_record_get returns record schema for type="schema".
428 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
430 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
432 Better SRW-to-Bib-1 diagnostic mapping.
434 ZOOM C and yaz-client announces SRU version 1.2 by default.
436 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
439 Fixed in yaz_sru_decode to allow other version than 1.1.
441 --- 3.0.10 2007/08/22
443 Added support for SRU scan for ZOOM.
445 Added support for the use of the older versions or Extended Service
446 Update in ZOOM. To faciliate this, an option "updateVersion" may be
447 set to the version , 1=first, 2=second, 3=third. The third version is
448 what ZOOM C has used so far. And that, obviously, is the default.
450 Added support for CCL queries in Z39.50 queries sent to the GFS (and
451 therefore in Zebra and in SimpleServer-based applications). The new
452 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
453 qualifier file used to transform incoming CCL queries into Type-1 RPN,
454 which is passed into the back-end search callback function.
456 Added support for HTTP Basic authentication in clients: the SRU/W
457 codec encodes the username/password elements of the PDU structure
458 appropriately, and these may be set using the "user" and "password"
459 options in ZOOM-C applications (the same options that are used for
460 Z39.50 authentication).
464 Fixed bug #1208: SSL appears to be broken in ZOOM.
466 Fixed bug #1206: Libxml2 include path weirdness.
468 Added oid_name_to_dotstring.
470 Allow elementSetName to be specified for ZOOM C record update.
472 Allow waitAction to be specified for ZOOM C based for Extended Services.
474 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
475 syntax OID. Bug introduced in YAZ 3 series.
477 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
481 Fixed bug #1157: yaz-client does not read .yazclientrc from current
482 directory. yaz-client now reads commands from file given by option -f
483 if specified; then tries to read .yazclientrc in current directory.
484 Failing that, it reads .yazclientrc from user's home directory.
486 Added support for correlationInfo Note and ID for Record Update via
489 Added yaz-client command querycharset which specifies character set for
490 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
491 (termListAndStartPoint).
493 Charset ISO5428:1984 is an alias for ISO5428-1984.
495 Implemented a way to perform scan in a result set using Z39.50. This
496 is achieved by attaching the result set name in the characterInfo
497 (type InternationalString) of OtherInformation in the Scan Request PDU.
498 The result set is identified in the otherinformation by the new OID:
499 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
500 This allows for scan in result set and faceted search . Zebra did some
501 of this in the APT term using attribute type 8 and value being result
502 set. Using the OtherInformation approach for this is cleaner and easier
503 to work with in proxies and the like. This facility can be used in
504 yaz-client using new command setscan which takes a result set as first
505 argument, start position (APT) as second.
507 Changed decoding of SRU XML packed records to deal with servers that
508 have recordData with XML data with multiple root nodes. Also make
509 comparison for recordPacking case insensitive. Again, one server
510 returns "XML" where others return "xml".
512 For SRU responses allow Content-Type application/xml as well as text/xml.
516 Fixed bug in character set conversion of BER strings. Bug introduced
521 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
523 For OID class, use oid_class consistently.
525 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
528 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
529 character set for bibliographic information interchange". By Giannis Kosmas.
531 Added documentation on new OID API.
535 Changes to generic frontend server interface: added new member
536 'query_charset' for bend_initrequest structure. A backend init handler
537 should set this member to its native character set for query terms.
538 When defined, the frontend server logic will announce this character set
539 to a client if the negotiationModel bit is set by the client. All server
540 implementors are encouraged to specify this. If a backend server does not
541 specify this a warning is issued using yaz_log(YLOG_WARN,..).
543 Added CCL utility to remove terms (stop words) from resulting RPN
544 tree. This is handled by functions with prefix ccl_stop_words_ .
546 New ZOOM C option, "rpnCharset", which allows client-side conversion of
547 terms in RPN queries.
549 Clean-up the CCL API. Moved some internal structures from ccl.h to
550 private header cclp.h. Changed ccl_parser_create so that a Bibset must
551 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
552 This is replaced by ccl_parser_find_str which takes a string instead.
554 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
555 libyaz.la is the core of YAZ except the generic frontend server and
556 does not depend on POSIX threads anymore. libyaz_server.la is the
557 generic frontend server facilities and uses POSIX thread functionality
558 if available. The libyaz.la no longer depends on POSIX threads because
559 the number of global structures is limited. NMEM no longer re-uses blocks
560 between threads ; it simply free's memory immediately but allocates in
561 "large" chunks as usual. We don't expect any performance penalties
562 because of this. The yaz_log system is still using a global log_level so
563 caution must be taken when modifying it with yaz_log_init_.. +
564 yaz_log_mask_str. This, however, should not cause any trouble because
565 these functions are called during initialization of application code
566 anyway. `yaz-config --libs server` returns libs for server applications;
567 `yaz-config --libs` returns libs for non-server applications.
569 New OID database - with public definitions in oid_db.h. Removed old OID
570 database including the head oid.h and definitions such as enum oid_value
571 and struct oident. The new OID database uses the same string names as
572 before but the 'protocol' is gone. There are now only two representations
573 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
574 converts from string to OID; functions with prefix yaz_oid_to_string
575 converts the other way.
577 Change to emit_term() in CQL-to-PQF query translation: when a term has
578 the /regexp relation modifier, do not process it for leading and
579 trailing "^" and "*", which have quite different meanings in regular
582 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
583 write handlers no longer carries a 'last' parameter. This will make
584 yaz_iconv flush "less" characters. A flush is performed by call to
585 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
587 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
588 removed, because function yaz_query_to_wrbuf does the same.
590 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
591 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
593 Deprecated MARC utility functions removed.
595 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
598 Branch split: YAZ_2_1_55_branch
600 --- 2.1.54 2007/03/16
602 Fix to ZOOM-C so that transparent reconnection is properly handled on
603 connections that are in asynchronous mode.
605 Fixed compilation on OpenBSD 4.0.
607 Large strings in GRS-1 records are now properly displayed in yaz-client.
609 Added character conversion support for "advancegreek"; based on patch from
612 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
613 sequence is met. Before the error was not set so it would be unknown.
615 Adjust yaz-marcdump MARC reader so that it skips until record separator
618 --- 2.1.52 2007/03/07
620 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
621 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
622 fd_set structure used as a bitmask for the FDs to be selected on.
624 Using ACX_PTHREAD macro to check for POSIX threads.
626 Fixed have-vsnprintf check.
628 --- 2.1.50 2007/02/23
630 Fixes for configure on BSD. Bug #900.
632 Added snprintf/vsnprintf wrappers for systems that don't have
633 limits (heavens forbid).
635 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
636 created before all previous tasks were completed and removed from the
637 task queue, the new task could be removed by a mistake.
639 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
641 Implemented pass-through CQL-to-PQF conversions. Bug #861.
643 Fixed bug #832: Problem with MARC/charset in yaz-client.
645 Fixed bug #668: save command line history for yaz-client.
647 Fixed bug #830: pkg-config support.
649 --- 2.1.48 2007/01/23
651 Extended ZOOM result set options with two options that may be read by
652 a client: resultSetStatus and presentStatus with values as specified for
654 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
656 Fixed bug #827: Using SSL fails on Debian etch.
658 Fixed bug #826: Weird looking chars for set of MARC records.
660 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
661 that is treated as an ItemOrder with itemRequest being an XML document
662 external. The value of "doc" is the content.
664 Extended the GFS search facility. New member of bend_search_rr
665 'estimated_hit_count' signals that hits is known to be an estmate
666 (higher or lower than real hit count). New member 'partial_resultset'
667 signals that the search was partial (hit count is lower or equal than
668 real hit count). For Z39.50, the information is stored in resultSetStatus
669 member of SearchResponse APDU. For SRU, the information is signalled
670 via SRU diagnostic 59: "Result set created with valid partial results
673 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
675 --- 2.1.46 2007/01/13
677 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
679 Added ZOOM_connection_peek_event.
681 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
682 the following new functions:
683 ZOOM_event_nonblock, ZOOM_connection_process,
684 ZOOM_connection_get_{socket,mask,timeout},
685 ZOOM_connection_fire_event_{timeout,socket}.
686 The existing blocking event handler, ZOOM_event, is a wrapper for the
687 + blocking ZOOM_event_sys_{poll,select}.
689 Implemented function ccl_xml_config which parses XML version of CCL
690 configuration (bug #798).
692 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
694 Added timings utility (yaz/timing.h)
696 --- 2.1.44 2007/01/03
698 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
701 Fixed bug #779: Rotation of apdu.log fails.
703 Fixed for character set conversions:
704 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
705 Honor G1 set in MARC-8 decoding.
707 --- 2.1.42 2006/12/17
709 Fixed bug #775: char conversion does not handle Alternative UTF-8
712 Implemented function yaz_marc_read_line which parses MARC line format
713 records. There is a wealth of formats out there. So far, this function
714 reads line records produced by yaz_marc_write_line.
716 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
717 more generic and easier to remember(!) options: -i format and -o format
718 which specifies input format and output format respectively - where
719 format is one of "marc", "marcxml", "line", "marcxchange".
721 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
722 does not print anything except warnings for records.
724 For yaz-marcdump, added support for MARC split into files (-s) with a given
727 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
728 spec, at http://www.loc.gov/standards/sru/record-update/
729 This has changed the binary layout of the following structs:
730 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
731 bend_update_rr . Patch by Ko van der Sloot.
733 Added GFS utility function bend_assoc_is_alive which returns 1 if
734 association is still alive (client is connected); 0 otherwise (client
735 closed connection). This allows busy servers to stop working for
738 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
739 been a separate piece of software. This version of ziffy has been modified
740 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
742 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
744 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
745 Client code may now interrogate options such as "init_opt_sort" to
746 find out whether the server claims to support various options.
748 --- 2.1.40 2006/11/27
750 Added utilities yaz_{set,get}_esn to set/get element set name from
753 Removed the build of libyazthread.la. The libyaz.so is the threaded version
754 of YAZ and has been so since YAZ 2.1.10.
756 Implemented ZOOM_record_error which returns error information for
757 record (surrogate diagnostic).
759 --- 2.1.38 2006/10/31
761 Updates for SRU Update by Ko van der Sloot:
762 1. Changed name from "operation" to "action"
763 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
764 versions in the code, marked as 'backward compatible'.
765 3. Added diagnostics for SRU Update.
767 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
769 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
771 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
773 For GFS, fixed problem with SRU diagnostic 'First record position out of
774 range' being issued for 0 hits.
776 zoomtst10 part of Windows Build.
778 --- 2.1.36 2006/10/13
780 Implemented yaz_filepath_comp which splits a path into file path
781 components (required by Zebra 2.0.3+).
783 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
784 BSD inspired license until now so this should not have any real impact on
785 anybody. See http://www.opensource.org/licenses/bsd-license.php
787 Fixed bug #687: Missing log lines.
789 Fixed bug #678: CQL to PQF translation does not preserve double-quote
792 Fixed bug #689: SRU diagnostics to be added.
794 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
795 whether a connection is idle (no more work do do).
797 --- 2.1.34 2006/10/04
799 Change type of optval from long to int for invocation of setsockopt with
800 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
802 Added support for specifying the max log file size for the Generic
803 Frontend Server. The size is given with option -r.
805 --- 2.1.32 2006/09/21
807 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
809 --- 2.1.30 2006/09/17
811 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
814 Fixed bug in Generic Frontend Server that could cause a server to stop
815 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
817 For the generic frontend server, the maximum record size is used as maximum
818 size of incoming packages (SRU + Z39.50). The value until was previously
819 only used in Z39.50 Init negotiation and, later, in a session controlled
820 sizes of records returned. This is controlled using -k option. It can be
821 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
823 --- 2.1.28 2006/09/04
825 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
828 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
830 New option for yaz-marcdump -lpos=value which allows setting a portion
831 of MARC header to a certain value.
833 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
835 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
836 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
838 --- 2.1.26 2006/08/15
840 Fixed problem with SRU mode type (soap, get, post) for yaz-client
843 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
845 --- 2.1.24 2006/08/08
847 Fixed MARC ISO2709 encoding routines to deal with character set
850 Minor changes to GFS logging. Database included in search request log
853 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
854 cached/multiple records.
856 Shared libraries are built by default on Unix+configure.
858 Changed cql2pqf transformation to use a different evaluation order. The
859 new order is: always, relation, structure, position, truncation, index
860 and relationModifier. Old order was: always, relation, relationModifier,
861 structure, index, position, truncation. Note that the the latter ones
862 override former ones for identical attributes.. The new scheme means that
863 it is possible to override any existing attribute with a relationModifier.
864 And also that it is possible to override everything for the index rule
865 (except the ones listed in relationModifier). No order is perfect but this
866 one, we believe, covers more real cases.. The "always" should have been
867 called "default", since the attributes there can be overridden with all
870 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
871 compilation phase, but also for yaz-config --cflags output. This allows
872 us to have public headers with Libxml2 stuff in them . It should also,
873 eventually, make Libxml2 checks redundant in packages using YAZ, such
876 --- 2.1.22 2006/06/15
878 Changed SRU update structure bend_update_rr so that SRU diagnostics are
879 stored in uri, message and details.. Previously diagnostics were stored
880 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
881 compatibility.. but he's probably the only one affected, so.
883 Added support for CCL, compiled on the client side, in ZOOM-C. This
884 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
885 input; the resulting query objects can be used for for searching with
886 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
888 YAZ' configure searches for OpenSSL by default.
890 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
891 SL_CTX_use_certificate_file. See
892 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
893 for more info. Thanks to Ko van der Sloot.
895 --- 2.1.20 2006/06/02
897 Bug #600: SRU GET, POST support for yaz-client. Introduced
898 command 'sru' which selects method SOAP/GET/POST.
900 Allow missingValueAction to be specified for the sortspec string -
901 function yaz_sort_spec. By default, the missing value action is null.
902 Use ! to specify "abort". Use = followed by stringvalue to specify default
905 Ensured that Present-handler (if defined) is called in GFS before any call to
906 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
907 searchRetrieve requests.
909 Documentation for YAZ is now based on the Docbook XML/XSLT using
910 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
911 is no longer depending on jade/openjade or docbook-to-man scripts.
912 PDF is no longer part of the distribution - but can optionally be
913 made using DSSSL/jadetex or FOP.
915 Added retrieval handling support in Generic Frontend Server to support
916 conversion between MARC/XML as well as XSLTtransforms. See
917 etc/yazgfs.xml for an example.
919 Added Authentication support to Generic Frontend Server in SRU
920 mode. Authentication using HTTP Basic is supported, as is the use
921 of 'x-username' and 'x-password' parameters in the request itself.
923 Added support for a new character set MARC8s identical to MARC8 except
924 that it converts combined characters to single Unicode characters in the
925 Latin-1 range (when possible).
927 --- 2.1.18 2006/04/24
929 ASN.1 compiler 0.4: generates brief Doxygen file header for
930 generated .h/.c files.
932 Utility yaz_iconv now supports conversion to MARC-8.
934 New facilities for the MARC module. The reading - and writing of
935 content are separate methods for the yaz_marc_t handle. The following
936 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
937 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
938 format). Write functions have prefix yaz_marc_write_.. The existing
939 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
940 available. Removed support for OAI-MARC and simplexml (not the
941 simplexml from PHP5).
943 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
944 to be returned for this connection.
946 --- 2.1.16 2006/03/31
948 Allow multiple languages and charsets to be specified with
949 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
950 negcharset iso-8859-1,utf-8
952 Translation of proximity nodes from CQL into PQF now works.
954 Moved to automake 1.8, 1.9.
956 Added function yaz_log_set_handler which allows a log handler to be
957 installed. This handler will be called for all log messages. Output
958 to file is also produced; but that can be disabled by passing NULL
959 fname to yaz_log_init_file.
961 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
963 For SRW (including GFS), accept application/soap+xml as content-type
966 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
967 produces NO stylesheet reference even if a default stylesheet is specified
970 --- 2.1.14 2006/03/14
972 Updated Windows package to include yazd.dll + yazd.lib for the
973 Development component.
975 If the environment variable YAZ_LOG is set, then it is used as a
976 string indicating the default level of logging to use if not
977 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
978 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
979 used as before. So, for example, to omit warnings from YAZ logging,
982 cql_transform() now map structure and other attributes before indexes,
983 so that index-specific structures and other attributes can override
984 defaults. So now a combination of mapping specifications such as:
986 index.dc.date = 1=date-modified 4=5
987 does the right thing.
989 cql_transform() now also respects the "always" mapping specification,
990 which establishes an initial set of attributes to be used for all
991 terms except where overridden by more specific attributes associated
992 with the index, relation or modifier.
994 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
995 which mode to use; one of "post", "get" or "soap" (SRW, default).
997 Fixes for yaz_iconv routines: changed trie-based character set conversions
998 to use only non-negative values for bit fields due to Sun's C compiler not
999 supporting negative values.
1001 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1002 sequences where not read correctly. Fix by Rustam Usmanov.
1004 Updated win/makefile to use options, settings which makes things
1005 compile with VS C 2005.
1007 --- 2.1.12 2006/02/01
1009 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1011 In ZOOM socket code, use select instead of poll on MacOSX.
1013 ZOOM-C now support client-side compilation of CQL into RPN that is
1014 sent to the server, enabling CQL to be used against all Z39.50
1015 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1016 ZOOM_query object, and submit it using ZOOM_connection_search().
1017 The CQL-to-RPN translation uses a configuration file, the name of
1018 which must be specified in the Connection's "cqlfile" option.
1020 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1021 function, which takes as its start-term parameter a ZOOM_query object
1022 (which may have had either CQL or RPN set into it).
1025 --- 2.1.10 2005/11/29
1027 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1028 GFS to support this as well. Backend handler, bend_srw_update, does the
1029 update work. Code contributed by Ko van der Sloot.
1031 Allow retrieval of Search Result-1 information in ZOOM by the use of
1032 options that are attached to a result set. ZOOM documentation updated
1035 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1036 UTF-8 conversion. Patch by Raj Patel.
1038 Added option -m to GFS to control formatting of timestamps in log file.
1040 Added 'exit' as synonym for 'quit' in yaz-client
1042 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1043 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1044 for the new members. Patch by Ko van der Sloot.
1046 Added support for SRU POST. It is supported for content-type
1047 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1049 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1050 Instead make the library libyaz.la multi-threaded. Threading as a whole
1051 can still be disabled by configure option --disable-threads. Previosly,
1052 with older GLIBCs there were problems with MT libs under Apache. This
1053 has now been fixed a long time ago.
1055 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1058 CQL module modified to be case insensitive for relations/indexes/operations.
1060 Fixed bug in CQL transform code: incorrect value relationModifieder
1063 Added 'show all' command for yaz-client which retrieves all results
1066 Added new yaz-client, xmles, which takes a (private) OID and
1067 a document to be sent as an extended service request.
1069 Describe new yaz-client commands wait_response and set_auto_wait.
1071 Increase TCP/IP listener backlog from 3 (which I am guessing was
1072 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1073 that the socket will queue as many incoming connections as it's able
1074 to handle ongoing connections. In other words, it will never now
1075 refuse a connection that it would be able to handle merely because
1076 it's not got around to accepting() enough of the pending connections
1077 yet. This is the behaviour anyway under Linux, where the listen()
1078 argument is ignored; but not under BSD and on systems such as
1079 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1080 YAZ-based servers should now be uniform across operating systems in
1083 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1084 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1085 This allows yaz-marcdump to read large MARC batches (>2 GB).
1087 Modified all YAZ source files - except the source which is auto-generated
1088 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1091 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1092 corresponding to the existing *_setl() function. These allow option
1093 values containing arbitrary valuues.
1095 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1096 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1097 except that it returns an indicator of whether or not the sort
1098 criterion was accepted (0 for OK, -1 for invalid).
1100 --- 2.1.8 2005/06/07
1102 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1103 MARC output rather than returning "new" buffer.
1105 yaz-client warns about unknown init options.
1107 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1109 --- 2.1.6 2005/05/24
1111 Added support for SRW sort in Generic Frontend Server. Patch
1112 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1113 sortKeys - or NULL if none is provided.
1115 Fixed bug #307: It was impossible to specify indefinite/no timeout
1116 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1119 Added support for multiple languages and charsets to be specified in
1120 ZOOM. Each charset/language is separated by a blank. If negotiation is
1121 in effect in init-response, Option
1122 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1123 Code based on patch by Vasiliy Osadchuk.
1125 Fixed bug #306: infinite recursion that occurred when calling
1126 yaz_log_level_init as the first call (before other log level or
1129 Fixed bug in scan handling in front end server: if preferred-Position-In-
1130 Response was non-present, a NULL pointer referece was performed.
1132 --- 2.1.4 2005/04/26
1134 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1135 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1136 now defined for all those error codes. So instead of putting 109 in
1137 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1138 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1140 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1143 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1145 Program yaz-client now exits and produces an error message if multiple
1146 Z39.50 servers are specified on the command line (none or one allowed
1149 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1152 --- 2.1.2 2005/03/16
1154 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1156 Fixed bug #272: Preserve spacing for CCL terms.
1158 --- 2.1.0 2005/03/14
1160 Added support for virtual hosts and multiple backend servers for
1161 the YAZ frontend server. The configution is XML based and
1162 support specificition of CQL to RPN mappings and explain information.
1163 See section "Virtual Hosts" in the YAZ manual.
1165 Extended OPAC display utility. OPAC display utility renders
1166 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1167 to supplement yaz_marc_decode_wrbuf.
1169 Fixed a bug in MARC decoder that could caused it to crash for some
1170 invalid MARC records. More diagnostics and warnings where added in
1171 XML output (warnings, etc are stored in comments).
1173 --- 2.0.34 2005/02/08
1175 Fixes for UNIX domain sockets. Bug #261.
1177 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1179 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1180 Added yaz_marc_subfield_str which defines subfield lead string which is
1181 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1182 yaz_marc_endline_str which defines end of fields string used in
1183 YAZ_MARC_LINE format. Default string is newline.
1185 Experimental support for MarcXChange. This format can be produced
1186 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1187 http://www.bs.dk/standards/MarcXchange.xsd
1189 Added yaz-client commands scansize that sets maximum number of
1190 entries to be returned by scan.
1192 --- 2.0.32 2005/01/11
1194 Added support for SRW scan in yaz-client and Generic Frontend Server.
1196 * Added whereInList member to SRW Scan Term.
1198 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1200 Fixed NMEM system to return aligned blocks on the smallest boundaries
1201 that are suitably aligned for all possible types on the particular
1202 architecture YAZ is being built for.
1204 --- 2.0.30 2005/01/04
1206 Fixed numerious warnings that was issued with newer versions of GCC.
1208 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1209 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1212 Make YAZ Generic Frontend Server slightly faster.
1214 Enhance (and reduce) logging for Generic Frontend Server.
1216 Revert YAZ log system so that it flushes every write operation
1217 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1219 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1220 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1221 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1222 will effectively disable old definitions.
1224 --- 2.0.28 2004/11/09
1226 Added yaz_log_time_format which specifies log format using
1229 Added yaz_log_module_level which returns mask for a module. Value
1230 is non-zero mask a if module is enabled; zero if disabled.
1232 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1233 in include/yaz/cql.h.
1235 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1237 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1239 Fixed bug #172: RPM builds does not enable SSL.
1241 Doxyfile.in part of dist. Doxyfile generated by configure.
1243 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1244 are given and the corresponding component does not exist.
1246 Extend CCL documentation in YAZ reference. Describe r=r.
1248 --- 2.0.26 2004/10/01
1250 Fixed MARC->MARCXML conversion to properly deal with
1251 fields, subfields, indicators having non-ASCII characters.
1253 Fixed MARC->MARCXML conversion so that ASCII control characters
1254 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1257 Added YAZ GFS support for conversion from Z39.50 surrogate
1258 diagnostics to SRW surrogate diagnostics.
1260 Bug fix: YAZ GFS did not return schema in explainResponse.
1262 --- 2.0.25 2004/09/30
1264 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1265 now converts recordSchema to elementSetName as well as schema URI.
1267 Fixed bug in COMSTACK that prevented HTTP request packages from being
1270 --- 2.0.24 2004/09/29
1272 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1273 does not require white-space before and after the dash in a range, e.g.
1274 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1277 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1278 due to new GCC removing "redundant" code.
1280 Added yaz-client commands scanpos and scanstep that sets preferred
1281 position and step-size for scan.
1283 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1285 Added CCL utility ccl_qual_buf which parses one or more CCL
1286 spec lines in a buffer.
1288 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1289 of name and value - ignoring empty lines and comments.
1291 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1293 Added odr_get_element_path which returns current element path for an
1294 ODR handle. This utility is useful in error handling or user-defined
1297 Added ODR_PRINT utility odr_set_stream which is is a more generic
1298 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1299 to a write function and pointer to close function. The close function - if
1300 non-NULL - will be called during odr_destroy.
1302 Fixed bug in CCL parser where truncation char was not removed from
1303 right side when truncation=both was in effect.
1305 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1308 --- 2.0.23 2004/08/11
1310 Fix buffer overrun in CQL parser when dealing with proximity (%).
1312 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1313 to UTF-8/UCS conversion is now only based on codetables.xml.
1315 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1317 --- 2.0.22 2004/08/06
1319 Add support for more "commit changes" in ZOOM (uses Extended Services).
1321 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1324 Yet another small fix for configure of SSL.
1326 --- 2.0.21 2004/05/14
1328 Fix SSL libs for configure when --with-openssl=DIR is given.
1330 --- 2.0.20 2004/05/10
1332 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1334 SSL comstack now uses yaz.pem certificate file on server side
1335 by default. Certificate filename can be configured by calling
1336 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1338 Fix bug regarding multiple calls to ZOOM_connection_connect.
1340 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1342 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1343 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1345 ZOOM now allows inspection of X509 peer certificate for verification.
1346 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1348 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1349 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1350 as "modular" but it simplifies things.
1352 Added cs_get_peer_certificate to that returns peer X509 PEM.
1354 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1355 NULL if SSL is unavailable.
1357 Documentation about MARC decoding tools.
1359 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1361 --- 2.0.19 2004/03/30
1363 Rename CHANGELOG to NEWS to follow GNU style packing.
1365 Fix bug with missing initialization of member in init_diagnostics.
1366 This bug affects threaded version of GFS server.
1368 --- 2.0.18 2004/03/20
1370 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1373 Ensure zlib.dll is packed with Windows install.
1375 --- 2.0.17 2004/03/17
1377 Fix encoding of xsd:string to use text instead of CDATA.
1379 Fix endless loop in CQL parser with unbalanced ".
1381 Use a more compact way to store MARC-8 conversion tables.
1383 --- 2.0.16 2004/03/16 Debian only
1385 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1388 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1393 --- 2.0.15 2004/03/01
1395 Another fix for decoding of XML packed records.
1397 --- 2.0.14 2004/02/25
1399 Fixes for Chunked encoding. White space not ignored after length spec.
1401 Update NS and use default NS for SRW diagnostic elements.
1403 --- 2.0.13 2004/02/23
1405 Implement ZOOM_resultset_cache_reset which resets record cache.
1407 Implement ZOOM_resultset_sort which sorts a result set.
1409 Implement chunked HTTP transfer.
1411 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1413 --- 2.0.12 2004/02/16
1415 Added member 'schema' to bend_explain_rr structure so that backend
1416 can specify explain record identifier. Defaults to Zeerex 2.0.
1418 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1420 --- 2.0.11 2004/02/16
1422 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1425 Added init command for yaz-client which sends "extra" init request.
1427 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1428 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1430 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1432 Make ZOOM error code for "invalid query".
1434 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1436 --- 2.0.10 2004/02/05
1438 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1441 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1443 Added option -p <file> to make Generic Frontend Server to write PID file.
1445 Added option -D to put Generic Frontend Server in background on its own.
1447 Make ZOOM C recognize option "password". If unset, "pass" is used
1448 (for backwards compatibility).
1450 Fixed a bug in Generic Frontend Server that could make it crash if a
1451 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1454 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1455 Must be issued before open, in order to be in effect.
1457 --- 2.0.9-6 2004/01/12 Debian/Windows
1459 Make the SRU server more picky WRT unknown params, etc.
1461 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1463 New YAZ client command, options, that sets Z39.50 options.
1465 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1466 options from a string of tokens (one token for each option bit).
1468 Update SRW diagnostic code messages.
1470 --- 2.0.9-5 2004/01/07 Debian/Windows
1472 Handle user defined stylesheet for SRW/SRU.
1474 --- 2.0.9-4 2004/01/06 Debian/Windows
1476 Fix bug in decoding of Content-Length.
1478 --- 2.0.9-3 2004/01/06 Debian/Windows
1480 Fix a bug with decoding of XML packed records.
1482 --- 2.0.9-2 2004/01/05 Debian only
1484 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1486 Fix bug in SRW/SRU diagnostics decoding.
1488 --- 2.0.9 2004/01/05
1490 Fixed bug in Generic Frontend Server which could drop records exceeding
1491 preferred message size. Reported and fixed by Irina Dijour.
1493 Fixed calculation of package size for structured records in Generic
1494 Frontend Server. Reported and fixed by Irina Dijour.
1496 Fixed namespace for SRW/SRU diagnostics.
1498 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1500 --- 2.0.8 2003/12/22
1502 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1503 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1506 CQL changes to reflect recent changes to the specification:
1507 * Documentation talks about context sets instead of index sets.
1508 * Documentation talks about indexes instead of qualifiers.
1509 * The CQL-to-PQF transformer's configuration file now uses
1510 "index.set.name = <attributes>" instead of the old form
1511 "qualifier.set.name = <attributes>". (Both forms are still
1512 understood but the latter is deprecated.)
1513 * CQL terms with no explicit index specified are now interpreted as
1514 cql.serverChoice instead of srw.serverChoice (which of course
1515 behaves exactly the same.)
1517 --- 2.0.7 2003/12/16
1519 MARC conversion can now generate ISO2709 output in another
1520 character set. yaz-marcdump uses this facility if you invoke it
1523 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1524 functions from there can be used from C++.
1526 --- 2.0.6 2003/12/04
1528 Frontend server now transfers memory from decoded packages to stream
1531 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1532 references to show up.
1534 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1535 the ZOOM Abstract API. The older names for the same options are still
1536 also supported for the benefit of old applications.
1538 ZOOM-C supports "implementationId" and "implementationVersion" options
1539 to go along with "implementationName". These allow the user code to
1540 specify identification strings to be sent to servers.
1541 Add OID for the new ExtLite attribute set.
1543 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1544 as requested/supplid by Ere Maijala <ere@atp.fi>
1546 For generic frontend server, reverse the order of
1547 "toolkit-supplied / application-supplied" strings sent as implementationId,
1548 Name and Version. Also, remove the spaces around the slash. This brings
1549 the GFS in line with the behaviour of ZOOM-C on the client side.
1551 Add function ZOOM_scanset_display_term.
1553 yaz-client shows scan displayTerm if present.
1555 Utility yaz-iconv is now installed by default along with the man page
1558 Extend configure check for OpenSSL to use pkg-config where available (such
1561 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1562 server to specify uid/gid/mask for socket using the format
1563 unix:[user=uid,][group=gid,][umask=mask,]file=path
1564 If file= is omitted the existing format is assumed, e.g.
1566 in which case the mask is 0666 (rw for everybody).
1568 Major restructure of YAZ source. All source in libyaz is in src directory.
1569 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1570 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1572 Added man page for utility yaz-marcdump (used to be called marcdump).
1573 yaz-marcdump is installed by 'make install'.
1575 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1576 of incoming package failed.
1578 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1580 Change prototype of odr_perror: add const to message string.
1582 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1584 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1585 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1586 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1587 DNS lookup. There should not be any compatibility problems with this
1588 assuming that blocking=1 or 0 is used.
1590 Fix bad reference in UNIX comstack in function cs_addrstr.
1592 Fix for compilation on AIX.
1594 The generic front-end server (server/seshigh.c) now supports returning
1595 Init diagnostics to the client in User-information-field, in
1596 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1599 --- 2.0.4 2003/09/04
1601 Allow any CQL relation (not just all,any,exact,scr).
1603 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1604 that features the same UI.
1606 Implemented command update0 in YAZ client which is equivalent to
1607 update but uses old of Ext Update ASN.1.
1609 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1610 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1611 Previously no OID was used for this info.
1613 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1614 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1615 returns 'malformed search term' otherwise.
1617 SortResponse member resultCount now set to NULL in sort handler of
1620 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1623 Add three new utility functions for translating OIDs between various
1624 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1625 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1626 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1627 char *oid_to_dotstring(const int *oid, char *oidbuf);
1628 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1630 Reverted modifications for ES Update definition for z_IU0Update
1631 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1632 is back to YAZ 2.0.2.
1634 String value attributes for CCL parser.
1636 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1637 which their FirstSearch server returns in Init responses, sometimes
1638 carrying useful diagnostic information when Init fails. This has the
1639 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1640 "z39.50/oclcui.asn", where its definition is somewhat different from
1641 what OCLC document on their web-site, as required to interoperate with
1644 Support for anonymous authentication in yaz-client. Use the command
1647 * Fix the OID of the Index Data-local "admin" Extended Service from
1648 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1649 the 1000, which indicates a locally-defined OID, was a mistake.
1651 --- 2.0.3 2003/06/20
1653 Fix CCL directive @case handling so that it affects string match for
1654 both CCL keywords and qualifiers.
1656 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1657 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1658 Decoder has been updated with ASN.1 changes as listed in
1659 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1660 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1661 z_IUUpdate, remains unchanged.
1663 ZOOM_record_get may now return a record in a specific character set.
1664 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1665 "from" is the character set of record as returned by target. "to" is
1666 the character set to be returned. If omitted, "to" is UTF-8.
1668 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1670 New ODR utility, odr_getelement, which returns name of element for
1671 which encoding/decoding failed.
1673 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1674 in cases where a required element was omitted.
1676 Bug fix: some MARC8 sequences were not converted.
1678 New ZOOM option "step" which specifies number of records to be
1679 retrieved in one chunk. Used in conjunction with "start" and "count".
1681 SRW support for yaz-client. Use scheme http: to use it, e.g.
1684 yaz-client no longer does (un)intelligent character set conversions
1685 by default. Can be enabled with charset and marc_charset commands.
1687 xmalloc trace fix for 64-bit systems such as DEC alpha.
1689 Solaris 2.6 compile fix.
1691 New function, cql_strerror() translates SRW error codes, as returned
1692 by cql_transform_error(), into human-readable English strings. Used
1693 in yaz-client diagnostics when appropriate.
1695 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1696 converts it into a type-1 query which is sent to the server. This
1697 makes CQL available for use with all Z-servers, as opposed to the tiny
1698 minority that can handle CQL queries themselves.
1700 --- 2.0.2 2003/04/28
1702 New Debian package layout similar to the Redhat Package layout.
1704 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1705 and search result respectively.
1707 --- 2.0.1 2003/04/25
1709 Redhat package is now several packages: libyaz (runtime libraries),
1710 libyaz-devel (development and documentation, and yaz (utility programs).
1711 Package spec file by Morten Bogeskov.
1713 New member 'schema' in struct bend_fetch_rr which the name of requested
1714 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1715 handler MAY set this to reflect the schema of the returned record.
1717 New member 'display_term' in struct scan_entry. GFS now sets member entries
1718 and allocates scan entries to be filled by user scan handler. In previous
1719 version, entries member was allocated by the scan handler. That still works,
1720 but the GFS will ignore member display_term - assuming it was NOT set by
1721 the handler. The fact that the GFS now allocates the entries both allows
1722 for new members and makes a scan handler easier to write.
1724 Fix CQL lex buffer overflow.
1726 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1727 SRU default recordPacking is string.
1729 SRU protocol support for frontend server.
1731 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1733 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1735 Added scan for the ZOOM shell (zoomsh).
1739 * String Identifers for Schemas (Amendment 5).
1740 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1741 Old definition for schema
1742 Odr_oid *schema; /* OPT */
1747 Z_InternationalString *uri;
1748 #define Z_Schema_oid 1
1749 #define Z_Schema_uri 2
1752 * resultCount parameter to Sort Response (Amendment 1).
1753 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1755 Support for SRW 1.0 over HTTP. This is an optional feature and
1756 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1759 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1760 on the same port. SRW SearchRetrieveRequests are mapped
1761 to bend_init,bend_search,bend_fetch,bend_close.
1763 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1765 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1766 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1768 ZOOM connections are SRW based if schem http is used for hostname
1769 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1770 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1772 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1773 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1774 distance=n, order=true/false, relation=le, prox unit=word. If
1775 n is omitted, distance 1 is used.
1777 Fixed problem with C compiler include path in wrong order.
1779 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1780 on Solaris. Patch from Ko van der Sloot.
1782 New MARC decode API. All new functions operate on a yaz_marc_t
1783 handle. The most important new functions are: yaz_marc_create,
1784 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1785 decode and destroy respectively. Decoder can produce formats
1786 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1787 include/yaz/marcdisp.h.
1789 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1790 to UTF-8, UCS-32, wchar_t or Latin-1.
1792 * Prototypes for yaz_iconv_-functions moved to separate header
1793 include/yaz/yaz-iconv.h.
1795 Make a few private functions 'static' in unix.c. This prevents
1796 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1798 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1799 are set when Init Response is received.
1801 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1802 but returns diagnostic set as well.
1804 New function yaz_strerror which is a portable wrapper for
1805 strerror/strerror_r/GetLastMessage.
1807 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1808 is returned for MARC. If type is "oai", then OAI MARC is returned.
1810 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1813 --- 1.9.2 2002/11/26
1815 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1817 Fix bad race conditions on SIGTERM and terminate gracefully in
1820 Move retrieval (data1) module to Zebra since nobody seems to be
1823 Add GRS-1 render for ZOOM using same format as yaz-client.
1825 --- 1.9.1 2002/10/05
1827 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1829 Fix broken ESpec handling in data1 module.
1831 SGML reader parses comments and makes them part of the data1 tree.
1833 Added several type casts so that YAZ compiles as C++ code.
1835 ZOOM didn't handle PDU encoding failures properly.
1837 Added more Bib-1 diagnostics (approved extensions).
1839 GNU configure: better check for iconv.
1841 More portable use of accept, getpeername. Check for socklen_t. Use
1842 int/size_t if socklen_t is not defined.
1846 PQF parser rejects bad queries - including those with extra
1847 characters in them. PQF parser used to silently ignore that.
1848 Cleaner API for PQF added, which allows you to get detailed
1849 error information for bad queries (see yaz/pquery.h).
1851 Fixed bug in ZOOM_record_get for type "database".
1853 Implemented mini iconv library supporting conversions between
1854 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1856 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1858 --- 1.8.9 2002/08/20
1860 Fixed ZOOM C record cache so that preferredRecordSyntax and
1861 elementSetName is used to check for already fetched records.
1863 --- 1.8.8 2002/08/02
1865 Added three members in bend_initrequest structure to facilitate
1866 character set negotiation.
1868 Fixed a bug in frontend server that could cause indefinite
1869 loops under rare conditions.
1871 Revised character set utilities (charneg.h) so that encoding
1872 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1874 For PQF, directive @term <type> sets term type for Scan/Search.
1875 Here <type> is general, string, numeric, null. The term type
1876 is inherited - just like @attr.
1878 New call odr_set_charset that sets character set conversion for
1879 international-strings on a ODR stream. Prototype is:
1880 int odr_set_charset(ODR o, const char *to, const char *from);
1881 The InternationalString is still represented as C string in YAZ
1882 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1883 won't). On the protocol level, you can use any encoding.
1885 Support for UNIX sockets in ZOOM.
1887 Solaris recv sometimes returns errno == ENOENT. It is treated as
1888 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1890 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1891 both client and server. Code by Morten Bogeskov.
1893 --- 1.8.7 2002/05/22
1895 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1896 that they can be used directly from Visual Basic. You must recompile
1897 your windows APP if you're using ZOOM.
1899 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1900 Commands "lang" and "charset" sets language and character set respectively.
1901 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1902 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1904 Attributes from multiple CCL fields may be OR'ed rather than merged
1905 using directive "@field or". Fields are still merged by default -
1906 equivalent to "@field merge".
1908 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1911 Fixed bug in zget for parameter ExtendedServicesResponse.
1915 --- 1.8.6 2002/03/25
1917 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1919 Client displays USR.1:SearchResult-1 (hits per term).
1921 Additional Search Info for search in Generic Frontend Server.
1923 Fixed CCL parsing of "field=s".
1925 WIN32 installer - using the excellent NSIS software from nullsoft.
1927 Fixed CCL parsing of "field = - <number>".
1929 Added function yaz_marc_decode that decodes MARC for line mode
1930 display or XML (similar to that used by JZKit).
1932 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1933 Z39.50. But ISO/ILL was, however.
1935 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1936 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1938 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1939 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1941 --- 1.8.5 2002/02/03
1943 New YAZ client features: Command completion and new commands:
1944 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1945 Code provided by Jacob Poulsen.
1947 New call oid_trav, that visits all registered OIDs via callback.
1949 Function ZOOM_record_get now returns const char pointer rather than
1950 void pointer. It saves a lot of type casts.
1952 For YAZ client, command "auth" now allows you to set authentication
1953 in IdPass style. It is enabled when three tokens are given - order
1954 is user, group and password.
1956 Fix memory leaks in MARC record handling for ZOOM.
1958 New option for YAZ client, -k <kilobytes> that sets
1959 maximum record size. Similar to -k option for generic frontend
1960 server and yaz-ztest.
1962 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1964 Prefix query parser reports "fail" when bad attribute set is given.
1966 Fix in MARC decoder. Proximity logging. Fix for attribute set
1967 in scan handler for server. Patches by Shigeru Ishida.
1969 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1972 Configure option --with-openssl=<dir> now works when a directory is
1973 specified. Patch provided by Morten Bogeskov.
1975 New option for YAZ client, -u <auth>, that sets authentication.
1977 ZOOM fix: error information was sometimes "missing", since error
1978 was cleared/reset too when it shouldn't.
1980 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1982 --- 1.8.4 2002/01/04
1984 Scan for ZOOM API. New object ZOOM_scanset. New functions
1985 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1986 ZOOM_scanset_destroy.
1988 New ZOOM function, ZOOM_connection_last_event, that returns type
1989 of last event (such as "receive data", "send data", "apdu received",
1992 New ZOOM option, schema, that specifies schema for retrieval.
1994 New CCL feature. Qualifiers can be aliases for one or more
1995 other qualifiers (if more than one is given, OR is used).
1997 ZOOM uses named result sets if target supports it.
1999 Two new YAZ client commands: . (dot, which sources a script of YAZ
2000 client commands), and ! (to execute shell command.). Implemented
2003 Working on Debian packages.
2005 --- 1.8.3 2001/11/19
2007 YAZ client enables named result sets only if target supports it.
2009 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2011 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2012 with key="host" to get same result.
2014 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2015 Function Z3950_resultset_record(s) returns references to records
2016 "owned" by resultset. To become owner use Z3950_record_clone.
2018 Function z_ext_record handles Extended Services. Thanks to
2021 --- 1.8.2 2001/11/12
2023 CCL Parser fix: ignore token comma when dealing with and-lists.
2025 Documentation updates for COMSTACK.
2027 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2028 Changed prototype Z3950_records. For some functions, int parameters
2029 were changed to size_t.
2031 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2034 New MARC decode/display function, marc_display_exl, which properly rejects
2035 non-ISO2709 records. YAZ client uses it.
2037 --- 1.8.1 2001/10/29
2039 Fix bug: local attribute set wasn't set correctly in PQF strings.
2043 * Old Z39.50 codecs no longer supported.
2045 Added ZOOM C binding. See http://zoom.z3950.org/
2047 Renamed states for COMSTACKs to avoid confusion with events.
2049 Implemented cs_look and proper cs_rcvconnect.
2051 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2053 Configure detects POSIX threads on OpenBSD.
2055 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2056 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2058 When error is returned from present handler, non-surrogate diagnostic
2059 is returned in present response (and fetch handler is no longer called).
2061 * Minor adjustments to pquery parser (PQF). Token characters may be
2062 escaped by using backslash (C-style).
2064 PQF parser allows string attribute values to be specified. For @attr,
2065 non-numeric characters after the equal-sign are treated as strings
2066 (e.g. @attr 9=title).
2068 CCL trunction character may be defined (@truncation in file)
2070 * function zget_ExtendedServicesRequest sets waitAction to
2071 waitIfPossible (was wait).
2073 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2076 CCL operator names may be set in field definition files (CCL_bibset).
2077 See ccl/bib1 for an example.
2079 Fixes in ASN.1 compiler for C++ compatibility.
2081 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2082 and "op_or" to avoid conflict with C++.
2084 Fixed problem with GNU readline detection on Redhat 7.0.
2086 Added step-size for Scan backend handler.
2088 Fixed bug that made the frontend server crash when no attribute
2089 set was specified for scan.
2091 Front-end server automatically switches to original working directory
2092 when installed as an NT service. Previously -w had to be specified to
2095 Added extended attributes for retrieval module (data1), so that data1
2096 records carry d1_readXML/SGML attributes. d1_read also supports
2097 null-data rules ( <tag/>)
2099 On UNIX when POSIX threads are available, a separate library libyazthread
2100 is created. Programmers should link with that library and the yaz library
2101 when using threads. The reason for the split was that some applications
2102 on Linux, such as Apache, doesn't work well when using shared objects that
2105 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2106 (or any frontend server) in SSL mode by specifying ssl: followed by
2107 address. Only tested on UNIX.
2109 Added feature for CCL module. Virtual structure s=al or s=ol generates
2110 and-list and or-list respectively instead of phrase search.
2114 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2115 log_mask_str. This was done to avoid name conflicts with other libraries
2116 (such as other PHP extensions).
2118 Added raw OID member for preferred record syntax (request_format_raw)
2119 and returned record syntax (output_format_raw) for backend fetch method.
2121 Config file yaz-config now accepts options so that it returns specific
2122 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2124 Shared library support for UNIX using GNU libtool.
2126 * Modified backend interface. Request/Response struct's replaced by
2127 one read/write C struct. For example bend_fetchrequest and
2128 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2129 Every handler - even search has to be registered in bend_init
2130 handler. This means that the YAZ library no longer refers to
2131 external functions and it makes it possible to make the whole
2132 thing a single DLL/SO.
2134 Added Segment handler for backend server.
2136 Added Zmbol/Zebra administrative functions to YAZ client.
2138 Threaded frontend server on UNIX (when POSIX Threads are available).
2139 Starting the server with option -T enables multi-threading.
2143 Added configure option --enable-comp/disable-comp to control use
2144 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2145 located in sub directory asn.
2147 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2148 in ${exec_prefix}/bin along with the other programs yaz-client and
2151 GNU automake used to maintain makefiles.
2153 Added several OID's.
2155 Changed retrieval module so that we can load records with no abstract
2156 syntax defined. Tagpaths in these records are fully composed of string
2159 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2163 On UNIX, the generated makefile now supports a proper 'make install'.
2164 The prefix can be set via GNU configure to set the install location
2165 (default is /usr/local).
2167 * YAZ programs client and ztest were renamed to yaz-client and
2168 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2169 locations, such as /usr/bin,/usr/local/bin,etc.
2171 * YAZ Header files were moved from include to include/yaz. YAZ Header
2172 files are referred to as include <yaz/log.h> rather than <log.h>.
2173 The YAZ include path (-I ..) is therefore the same as before. Programmers
2174 should update their #include statements or use -Ipath/include/yaz
2175 instead. The main motivation for doing this change is that YAZ header files
2176 can be installed in "standard" locations /usr/include,/usr/local/include
2177 without introducing conflicts, since ALL YAZ header files are stored
2178 in subdirectory yaz (under /usr/include for example).
2180 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2181 rather than project/workspace files. We switched because project files
2182 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2185 Changed name of logging function, logf, to yaz_log, to prevent name
2186 clash with some math-log functions. The YAZ header log.h defines logf
2187 to yaz_log (#define) so there should be no incompatibilities by this
2190 Added bend_start/bend_stop handlers for server. These handler are
2191 called on start/stop of server. For windows they are called whenever
2192 a service is started/stopped.
2194 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2195 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2196 in util/yc.tcl. The auto-generated C code structures are, in a few
2197 cases, incompatible with the old decoders. There are differences in the
2198 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2199 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2200 The preprocessor variable ASN_COMPILED is defined when the compiled
2201 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2202 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2203 wish to use the old encoders/decoders you can specify --disable-yc
2206 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2207 version so that it supports both new - and old version of DB Update
2209 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2210 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2211 change. The name parameter can be set to 0 in which no name is specified
2212 for the construction. The macros odr_implicit and odr_explicit sets name
2213 parameter to zero for the construction involved. New macros
2214 odr_implicit_tag and odr_explicit_tag are similar to the others,
2215 except that a name parameter is added. For programmers' that don't use
2216 ODR they probably only need to change the call to z_APDU and z_External.
2218 Added access control facility by interfacing the TCP wrapper library.
2219 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2220 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2221 name of the daemon and enables the access control as specified in
2222 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2224 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2225 den Dool <H.M.vdnDool@kub.nl>.
2227 Added reference ID parameter to most functions in server API - refer
2228 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2230 Changed name of ccl library to libccl.a (was ccl.a).
2232 Fixed bug in decoder for Explain (Category TargetInfo).
2234 Added support for GNU readline in client. Thanks to Jacob Poulsen
2235 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2237 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2238 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2239 IMPLEMENTATION! This change was made to the development version before
2240 the ZIG decided to retract the amendment. If any users MUST be
2241 compatible with the original Update definition, PLEASE CONTACT US, and
2242 we will include a separate definition corresponding to the old Update
2243 ES. Note that because of the change to the ASN.1 of the
2244 TaskPackageRecordStructure we cannot define a single structure that
2245 will support both versions.
2247 * Added const modifier to buffer parameter for some ODR/BER encoding
2248 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2249 completeWAIS, odr_dumpBER.
2251 Fixed bug in client.c which caused a crash when a scanResponse didn't
2252 contain positionOfTerm.
2254 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2255 * will cause an error in a client if a non-YAZ target sends both a
2256 * list of Scan entries and non-surrogate diagnostics.
2258 Retrieval module enhancements. Tag sets may be typed in the reference
2259 to it. From the .abs-file the "tagset" directive takes a third optional
2260 integer type for the tag set referenced. From a .tag-file the "include"
2261 directive takes a third optional type as well. The old "type" directive
2262 in the tag set itself is still recognized but acts as the default type
2265 Backend interface change. Individual Scan terms returned from bend_scan
2266 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2267 in include/backend.h.
2269 Retrieval module enhancements. Multiple tag sets and attribute sets may
2270 be specified in abstract syntax specs. Revised the error/warning for
2271 logging messages reported by the retrieval module when reading the
2274 Object Identifier system (oid_..) changed. The API is backwards
2275 compatible but the oid-routines now allocates new OID's when needed.
2276 Raw OID's may be specified in oid_getvalbyname.
2278 YAZ now uses GNU configure to generate Makefile(s).
2280 * Minor changes in some of the member names of DeleteResultSetRequest and
2281 DeleteResultSetResponse. See include/proto.h.
2283 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2284 and added member 'languages' in TargetInfo (which was missing).
2286 Changed the way attribute sets are handled in the retrieval
2287 module. These are now cached, just like the abstract syntaxes
2290 Changed YAZ so that it links with compiled ASN.1.
2292 Added Explain-schema definitions and mapping routines. The following
2293 Explain categories have been implemented: AttributeDetails,
2294 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2296 Fixed minor bug in Windows version of Server Library.
2298 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2300 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2302 Added EXTERNAL: UNIverse Resource Report (non-standard).
2304 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2305 ENUMERATED and SET OF.
2307 * Added 'const' to some of the char pointer arguments for the
2308 functions, data1_read_node, data1_getelementbytagname,
2309 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2312 Fixed bug in data1_insert_taggeddata - the last_child member of
2313 parent wasn't initialised.
2315 * Changed data1_read_record and data1_read_node so that the supplied
2316 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2317 doesn't refer to any parts of the "SGML"-buffer.
2319 Fixed bug in server library (Windows version of statserv_remove).
2321 * Changed code so that it compiles as C++. The type definition
2322 of Odr_fun which is a member of Odr_arm was changed. The result is,
2323 that an explicit typecast is needed for the fun pointer when
2324 using Odr_arm - as in:
2325 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2327 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2329 Implemented the new structured date and time definition as approved
2330 by the ZIG. Added schemaId element to the specificTag in Espec-1
2331 (also approved at the last ZIG). Thanks to RVDM.
2333 Added some Object identifiers (RVDM).
2335 Changed the Update Extended Service (RVDM).
2337 Added command "refid" to client which specifies referenceId for
2338 the following requests.
2340 Implemented extended service handling for server. See ztest.c
2341 for an example as well as backend.h. New handlers are registerd
2342 in the Init handler.
2344 * Changed interface for sort in server.
2346 Added new members to statserv_options_block. It allows a server
2347 to read options from another source than just the command line. Thanks
2348 to Charles Woodfield.
2350 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2351 renamed to zboolean. Some C++ compilers complained about the name.
2353 Minor changes to gils.abs. Added index 's' (sort) on title
2354 and date/time-last-modified.
2356 --- 1.4pl2 1998/1/30
2358 Fixed bug in server library regarding inetd mode (-i). This bug
2359 was introduced by release 1.4.
2361 --- 1.4pl1 1998/1/29
2363 Added sort facility in client and backend server interface.
2365 Fixed problem with dependencies in Makefile(s).
2367 Fixed bugs for encoders/decoders of extended services and
2370 Implemented sub-tree feature for schemas. Sub-trees are
2371 referenced in *.abs-files. See explain.abs for an example
2372 of the use of this feature.
2374 Modified bib1.att; local attributes for ANY didn't include
2375 ANY itself (only affects use of the retrieval module).
2377 Fixed bug in plain SGML reader in function data1_read_node:
2378 tags with prefix "var" was incorrectly interpreted as variants.
2380 Added feature "sub-schemas" to enable references to - and definitions
2381 of - group of elements.
2383 * Removed member parent from type data1_element (in data1.h).
2385 Implemented function odr_nullval() that returns the value of
2388 * Removed member num_children from data1_node (in data1.h).
2390 Made NT service interface part of the server library. The
2391 function statserv_main uses the NT service when required and
2392 calls the statserv_start / statserv_close routines.
2394 Routine zget_SearchRequest and zget_PresentRequest fills
2395 resultSetName/Id member with "default" instead of "Default".
2397 Fixed memory leak in server. Request queue member wasn't freed.
2399 Fixed nmem_exit so that memory is freed.
2403 Revised the CCL parser utility to be thread safe.
2405 Added function, oid_ent_to_oid, to replace the function
2406 oid_getoidbyent, which is not thread safe.
2408 * Added nmem_init and nmem_exit to initialize and release
2409 NMEM resources. Function nmem_init should be called once in the
2410 initial thread before NMEM/ODR is used. statserv.c and client.c
2411 have been changed accordingly. The change was necessary to make
2412 NMEM thread safe. The NMEM memory pool is shared amongst threads
2413 in a process. Unix-based applications will still work fine without
2416 Added NT Services interface for the the Z39.50 (statserv) Server.
2417 Refer to the ztest.c source on the usage.
2419 Windows 95/NT port using MSVC5.0. Project files are included in the
2422 * Defined new 'global' handle for the retrieval (data1) system. The
2423 new handled, data1_handle, describes the state of the data1 system.
2424 This handle is passed as first argument to virtually all
2425 data1 related routines. The functions data1_create and data1_destroy
2426 creates and destroys a data1 handle respectively.
2428 Added ODR encode stream member to all backend request structures
2429 init, search, scan etc. This stream should be used to allocate all
2430 memory used for the response when thread safe operation is needed.
2432 Changed the comstack utility, cs_addstr, to be thread safe. The
2433 returned hostname string returned by the function is now part the
2436 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2437 function. The cs_straddr takes a COMSTACK handle as argument, so this
2438 function must be used after cs_create and before bind/connect.
2439 This function is thread safe.
2441 Moved test server to 'ztest' directory - generic server code still
2442 in 'server' directory.
2444 Made prefix query (pquery.c) utility thread safe.
2446 Added new function modifier YAZ_EXPORT to 'export' public DLL
2447 functions when using windows (see include/yconfig.h).
2449 Added definitions to the OID database (util/oid.c) (RVDM).
2451 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2453 Added call to ccl_rpn_delete in client program.
2455 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2456 release of RPN structure.
2458 Added support for C++, headers uses extern "C" for public definitions.
2459 With input from RVDM.
2461 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2462 Thanks to Ronald van der Meer (RVDM).
2464 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2466 Added support for private extensions to the OID database
2467 (oid_setprivateoids()). Thanks to RVDM.
2469 Added optional, physical ANY (key replication)
2471 Fixed null-reference problem in GRS-1 output filter.
2473 Proximity operator added to Prefix Query Format (PQF).
2475 In test client command "base" accepts multiple databases.
2477 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2481 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2483 Smallish bug-fixes in the new encoders/decoders (explain).
2485 Bug fixed in DeleteRequest.
2487 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2489 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2491 Added SOIF syntax (using private OID for now) to retrieval module and client.
2493 Added Update extended service.
2495 Added SearchResult-1 additional info structure.
2497 Added optional CCL (ISO8777) interpreter as separate module. Available
2500 --- 1.2 1996/6/10 (1st anniversary release)
2502 Added Summary record syntax. Lightly tested.
2504 Added OPAC record syntax. Untested.
2506 Added ResourceReport service encoders/decoders. Untested.
2508 Fixed bug in z_Unit - wrong tagging on unitSystem.
2510 Fixed bug in the DiagRecs decoder.
2512 Added options for max PDU size and session timeout to frontend-server.
2514 Added documentation of query-language parsers and other supporting utilities.
2516 [frontend-server] Added Attribute set to the bend_scanrequest API.
2518 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2519 surrogate diagnostics were generated.
2521 [retrieval] Allow multiple local values for attribute.
2523 [retrieval] Allow multiple attributes per element in .abs files. index type.
2525 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2527 --- 1.1pl2 1996/4/10
2529 Minor changes, mostly specific to Zebra's requirements (retrieval)
2533 Repaired bug in frontend server when running multiple listening
2534 endpoints in dynamic mode.
2536 z_External() now won't break if a known, ASN.1 value comes encapsulated
2537 in an octet-string. The value will pass through unmodified in an Odr_oct.
2539 Added a bit of code to the demo client to decode & display
2540 ASN.1-structured records represented in the octet-aligned branch of
2541 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2543 Added z_ext_getentbyref() to the ASN module. Doc updated.
2545 * Completed the SCAN definition in the ASN module. This may break SCAN
2546 code based on older YAZ-versions at compile-time. The fix is easy -
2549 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2550 under the SCAN definition. Remember to initialize this, server-people.
2552 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2553 that this does not extend to ODR and ASN.
2555 Comstack allows insertion of established socket (primarily for
2556 inetd-operation of servers). Doc updated.
2558 Front-end server can now start from the inetd in TCP mode. Doc
2561 --- 1.0pl4 1996/1/24
2565 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2566 the rank and record number.
2568 Adjustments to the frontend server.
2570 Fixed diagnostic BER dumper. It ignored the file argument.
2574 Various changes to retrieval module.
2576 Changed the union discriminators of the protocol files from enums to
2577 ints paired with #defines.
2579 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2582 *Changed operator in the RPN structure to 'roperator', again to avoid a
2585 Fixed problems in Explain decoders/encoders.
2587 --- 1.0pl2 1995/12/6
2589 Memory bug in log module fixed.
2591 --- 1.0pl1 1995/12/5
2593 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2595 Bug in Explain DatabaseInfo module fixed.
2597 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2601 The shift to v1.0 signals that we now consider the *core* functionality
2602 of YAZ reasonably stable (the core being more or less equivalent to
2603 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2604 tested (Explain not at all - though that will happen soonish).
2606 Minor changes to code to support Windows port.
2608 Various minor changes after we're getting to use GRS-1 & co. more.
2610 Added Espec-1 format.
2612 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2613 of the protocol and it cannot be selected when encoding (maps into 'string'
2614 when decoding). Needed to talk to some servers.
2616 Demo client can request simple element set names.
2618 Added Diagnostic Format encoders/decoders.
2620 Added simple Close handling to frontend server (no hooks for resource
2621 reporting yet), and demonstration client.
2623 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2625 --- 1.0b3 1995/08/24
2627 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2628 handled incorrectly when records were requested in the searchResponse. This
2629 will only affect you if you use the frontend-server.
2631 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2632 Test-client will ask for and print GRS1. Ztest will return dummy records
2635 Added Explain encoders/decoders to the service-level API. Untested.
2637 Added Extended Services: Item Order encoders and decoders to the Service-
2638 level API. Untested. We could use a recent copy of the pertinent bits
2639 of the ILL protocol to add those bits.
2641 Added diagnostic format 1 encoders/decoders to the service-level API.
2644 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2645 odr_cons.c, which causes a more correct output.
2647 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2648 was always set to 0 when no records were requested in the searchRequest.
2650 * Added better external-handling. This shouldn't harm old code that
2651 *encodes* externals. It can break code that looks for a
2652 'single-ASN1-type' representation, since those types that are known
2653 are now decoded immediately. Look at the SUTRS sample code in
2654 seshigh.c and client.c. Documentation updated.
2656 Handling of structured records in bend_fetchresponse. Length -1 marks
2657 structured record, type is deduced from format field.
2659 --- 1.0b2 1995/06/27
2660 Fairly quick maintenance release to add SUTRS support.
2662 Fixed handling of SUTRS records in the demonstration client.
2664 * Added format field to the bend_fetchrequest and bend_fetchresponce
2665 structures of the backend API (frontend server). When the record is
2666 returned, the value of the format field is mapped to an OID. The
2667 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2668 of the record. The special value VAL_NONE in the bend_request means
2669 that no specific format was requested by the client. Documentation
2670 updated accordingly. Test server (ztest) will return a fixed dummy
2671 SUTRS record if your client requests SUTRS.
2673 Documentation updated accordingly.
2675 You can now set external libraries and RANLIB support in the top-level
2679 First public release.
