3 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
4 are wrappers for pthreads or Windows. For Windows these are put in
5 a separate DLL: yaz_cond4.
7 libyaz.la (whole source) is compiled with thread. If thread support
8 is enabled enabled, all source of YAZ is compiled with treading support.
9 This allows core utilities such as yaz_log to use thread facilities.
10 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
11 thread utilities. This commit moves mutex utilities (mutex.c) from
12 libyaz_server.la to libyaz.la.
14 yaz-json-parse displays leading text until error.
18 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
19 patch from Giannis Kosmas.
21 SRU: no longer URL encode SRU database. The URL for an SRU server is
22 a URL and such is alreeady encoded - at least when given with leading
23 http:// or https://. This reverts behavior to YAZ 3.0.50.
25 Support for new MARC XML notation TurboMARC which like MARCXML is a
26 complete representation of MARC/ISO2709.. This one, however, is more
27 compact and allows for faster processing with XSLT. TurboMARC can be
28 used in the marcdisp.h API, from the yaz-marcdump utility and from
31 yaz-ztest can be configured - via the database - to perform certain
32 delays when it performs operations search, present and single record
33 fetch. This allows testers to make yaz-ztest act as a real or even slow
34 Z39.50 server. Refer to the yaz-ztest man pages for details.
38 wrbuf_destroy allows NULL WRBUF passed to it.
40 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
42 Add ZOOM_connection_close.
44 No fixed size buffers for ZOOM shell - bug #3257.
46 tstodr: make it work on s390 platform.
48 New icu iterator-functions. The new icu_iter-functions makes it possible
49 to use ICU chains from many threads.
51 yaz-client: better syntax check for show command.
55 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
58 New simple local-file XML include facility which allows file glob-patterns.
59 Refer to yaz/xml_include.h.
61 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
64 ZOOM_record_get supports new parameter "format" which makes it format XML
67 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
68 JSONText in ECMA-262) is JSONValue, not JSONObject.
72 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
73 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
75 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
76 POSIX/Unix builds .so with major version 4.
78 Remove old LOG_-defines from log.h. They have been obsolete and
79 undefined by default for the last 5 years.
81 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
83 GFS: Remove socket (int *fd) from search_rr handler. The socket
84 descriptor ptr is a facility that allowed a search handler to supply
85 a socket which would serve as a callback - when search was complete.
86 This facility has now been in use for years.
88 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
89 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
90 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
91 returns 'const char *' rather than 'char *. The returned string is
92 read-only and should not be modified by applications. COMSTACK cs_close is
93 now a void function - it no longer returns int. No applications check for
94 the value and the implementations has always returned 0.
96 ZOOM: use size_t for scan hit counts and str size. Functions
97 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
98 occ (hit count) and len (string length) are now of type size_t pointer
99 rather than int pointer. This is to be able to represent large hit counts
100 and to also just to use the proper type for string length (strlen result).
102 New JSON parser. Refer to include/yaz/json.h .
104 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
105 Used to be int in some cases. Many wrbuf_-functions used to return an int
106 indicating some length.. These return values were never used. And so they
109 ODR: odr_malloc, odr_total now takes size_t for size.
111 clone_z_type: fix leak; occurred for encoding failures.
113 --- 3.0.52 2009/12/03
115 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
116 bug was introduced in 3.0.51.
118 --- 3.0.51 2009/12/02
120 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
122 tcpip comstack: fix leak for getaddrinfo.
124 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
125 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
126 Decoding of SRU "path" database is performed by private function
127 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
128 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
130 yaz-client: honor base command for SRU. Change when database setting
131 is applied for SRU and ensure it is kept when a connection is reset.
132 Change also the way errors are displayed or SRU (decoding of packages).
134 --- 3.0.50 2009/11/02
136 Add support for extra request / response data for SRU codecs and GFS.
137 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
138 for extra data response buffer and length. For the GFS, both request
139 and response data (XML) is carried in extra_args and extra_response_data
140 for the search handler. Patch by Ko van der Sloot.
142 ZOOM: For queries that cannot be converted to the specified rpnCharset,
143 ZOOM now returns a diagnostic on the client-side ('invalid query' /
144 10010). This fixes bug #2113.
146 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
147 cmdfile included a 'quit' command that would result in a memory violation.
149 --- 3.0.49 2009/10/01
151 Make a number of functions defined in xmlquery.c static. These have
152 never been declared in a public header file (yaz/xmlquery.h) and was
153 made public by mistake.
155 Improve speed of character conversions (iconv utilities). This makes
156 conversions from MARC-8 faster.
158 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
159 unless type desired is "raw". This will prevent type "xml" from
160 returning ISO2709 .. Which obviously can not be XML parsed.
162 Fix memory leak in ZOOM that would occur if option apdulog was used
163 on a re-used connection.
165 Frontend server logs HTTP requests.
167 Frontend server now sends Z39.50 close when it times out (sesssion has
168 been idle for too long). Versions 2.0.30 and earlier also sent close.
169 But due to a mistake this was disabled in all versions after that, i.e.
170 the server would just close the socket immediately.
172 yaz-client emits a better message when receiving an unrecognised
173 userInformationField.
175 Skip zero-length subfields when decoding ISO2709. This rare case happens
176 if a record has two FS characters in a sequence. Without this patch
177 there would be a reference beyond char array in using_code_len fragments
180 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
182 --- 3.0.48 2009/08/28
184 The show command offered by the zoomsh command now takes a 3d optional
185 parameter type which is what is passed to ZOOM_record. If the type
186 argument is omitted, "render" is used.
188 RPN to CQL conv may use USE string attributes (bug #2978).
190 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
192 --- 3.0.47 2009/07/08
194 Function yaz_xml2query allows a diagnostic element in the PQF XML
195 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
196 code and additional info respectively.
198 The BER BOOLEAN is now the integral type Odr_bool which still happens
199 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
200 typedef'd to Odr_int. This is still an integral 'int', but it may be
201 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
202 ASN-1 compiler as well as programs has been updated to use the new types.
204 --- 3.0.46 2009/06/08
206 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
207 only the bibliographic record was rendered. For type=opac, an OPAC
208 record is only returned if it is present.
210 iconv: small fix for encoding of advancegreek.
212 yaz-client: avoid double display of SRU/SRW records (bug #2798).
214 yaz-client: option auto_reconnect=on really reconnects.
216 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
218 server: avoid null ptr ref for for yaz_poll errors.
220 build: fix RPM build for RHEL 5.3.
222 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
224 --- 3.0.45 2009/03/31
226 Fixed bug #2709: TCP connect returns Invalid argument.
228 Fixed compilation for mingw.
230 Honor charset for raw records (ZOOM_record_get).
232 Fixed use of errno for threaded mode that was seen on Solaris 10.
234 Fixed argument passing with blanks in value for Windows Service.
236 Disable YAZ' own log rotate by default (no 1 GB limit).
237 The variable l_max_size which specifies the log file limit is set to 0
238 (DISABLED): This is due to the fact that YAZ is most often deployed using
239 logrotate. Also YAZ can not perform log rotate because of unsufficient
240 permissions (setuid).
242 --- 3.0.44 2009/02/17
244 List supported encodings in man page for yaz-iconv.
246 Fixed missing SSL libs for --libs output
248 Re-established OID record syntax application-xml. Nobody should use it
249 but we don't want to change soname because of this symbol being absent.
251 --- 3.0.42 2009/02/02
253 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
255 Added member named_result_sets for init handler struct for the GFS. This
256 allows a server to disable named result sets.
258 Removed OID record syntax application-xml.
260 Added support for rule-based transliterator for ICU wrapper of YAZ.
262 Fixed bug #1902: yaz-icu XML output.
264 Make YAZ checks Emacs friendly.
266 BITSTRING value shows value. Bug #2346.
268 ISO2709 decoding: skip control characters from indicator data.
270 Omit sort key by default in yaz-icu's output.
272 Allow combined single char options (again) for YAZ' options function.
274 Utility yaz-marcdump got option to display YAZ version (-V).
276 Allow YAZ to use ICU 3.4.
278 Added new ICU test case which illustrates removal of diacritics.
280 --- 3.0.41 2008/12/29
282 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
284 --- 3.0.40 2008/12/29
286 For configure, using option --without-xml2 also disables Libxslt/Libexslt
289 Fixed bug #2352: yaz-marcdump crashes for certain record.
291 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
293 Added support for Danmarc2 to UTF-8 conversion.
295 Added support for ISO5426 to UTF-8 conversion.
297 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
298 implementation version.
300 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
302 --- 3.0.38 2008/11/10
304 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
305 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
307 ZOOM C now interprets databaseName option for ZOOM connection as path
310 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
312 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
314 Dummy Libxml2 types no longer defined in headers of YAZ'.
316 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
319 --- 3.0.36 2008/09/26
321 Various ODR chapter fixes.
323 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
325 Added missing source for Windows compilation, mutex.c.
327 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
329 For SRU connections in ZOOM all records up to "count" are now fetched.
331 Fixed crash in generic frontend server (and yaz-ztest) which occurred
332 in Windows due to bad error handling for Libxml2.
334 Added facility for sending arbitrary records (ASN.1 any) using
335 ZOOM C's Extended service update. Patch by Sam Reynolds.
337 New options for ZOOM C's connection, logapdu which makes ZOOM log
340 --- 3.0.34 2008/06/18
342 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
344 --- 3.0.32 2008/06/12
346 Fixed memory violation that could occur when decoding UTF-8. This bug
347 was only present in 3.0.30 of YAZ.
349 --- 3.0.30 2008/06/06
351 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
352 GNU TLS is used by default (if found).
354 yaz-ztest returns OPAC records if a client asks for OPAC.
356 Improved speed of MARC-8 encoding.
358 Added support for lossy and loss-less MARC-8 encoding.
360 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
362 Added new Windows Service wrapper (sc).
364 yaz-client's itemorder command may now send a file.
366 Fixed yaz-marcdump to allow the use of NS prefix for record element.
368 Added new function yaz_log_xml_errors.
370 Allow (but warn) unknown XML attributes in MARCXML parsing.
372 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
374 The UTF-8 to MARC-8 conversion now uses a different set of characters
375 for Greek symbols. Bug #2120.
377 --- 3.0.26 2008/02/21
379 Added yaz_daemon (daemon.h).
381 Fixed bug #2068: pkg-config trouble
383 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
385 --- 3.0.24 2008/01/28
387 Document --with-xml2 option.
389 Added OPAC XML XSD (etc/opacxml.xsd).
391 Allow glob mask for name attribute in retrieval element for the
392 generic frontend server's retrieval facility.
394 Changed yaz_poll_poll to return yaz_poll_except for all returned events
395 except POLLIN/POLLOUT.
397 Fixed error handling in cs_listen. Bug #2037.
399 --- 3.0.22 2008/01/20
401 Fixed version in yaz/yaz-version.h.
403 Fixed bug #2027: Crash when closing connection.
405 Changed configure so that ICU support is only enabled if only ICU
406 and Libxml2 is available (because the ICU chain is XML based).
408 --- 3.0.20 2008/01/15
410 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
411 is built. Only this DLL depends on the ICU runtime.
413 yaz-ziffy is no longer part of YAZ. It is distributed separately by
414 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
416 Changed license of CCL module to 'Revised BSD'. After consultation with
417 remaining members of the original EUROPAGATE consortium, we are re-issuing
418 the CCL module without a separate license. The software was developed by
419 Index Data as part of a research project. The special license was included
420 to help feed usage information back to the project consortium to support
421 project evaluation. At this time, the project consortium has long-since
422 disbanded, and the majority of the original principals have retired. At the
423 same time, we have significantly modified the software during the following
424 years, to the point where very practically no original code remains. To
425 simplify re-use of the software, we have contacted those members of the
426 consortium who could be reached, and agreed to re-issue the module as a
427 proper part of the YAZ package.
429 Tcl scripts uses /usr/bin/tclsh as preferred shell.
431 CQL closer to being version 1.2 compliant. CQL also allows free-form
432 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
435 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
436 bug could make Extended services handling crash in the ZOOM layer. This
437 bug was only present in YAZ 3.0.18.
439 --- 3.0.18 2007/12/19
441 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
444 yaz-marcdump reads and writes collection wrapped records.
446 Handle OPAC for record conversion module.
448 Fixes for ICU wrapper.
450 Allow ICU libs to be controlled with --with-icu .
452 --- 3.0.16 2007/11/12
454 Added yaz_poll which is a wrapper for select/poll. When poll is available
455 and non-buggy, it is used, by yaz_poll . This allows more than 1024
456 sockets to be in use.
458 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
459 functionality through an XML based configuration (ICU chain). This system
460 is useful for search facilities such as Pazpar2 and Zebra that needs to
461 perform tokenization of indexed material. The ICU code in a separate
462 library libyaz3_icu.a.
464 Added HTTP tunnel facility for COMSTACK, bug #1752.
465 This is a facility that allows a Web proxy, such as squid, to tunnel
466 Z39.50 traffic. This facility is "transparent" to must applications
467 using YAZ. It's enabled by using pseudo transport connect: followed by
468 the proxy address, followed by command, then follwed by he regular
469 "virtual" addresss. For example,
470 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
472 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
474 --- 3.0.14 2007/09/21
476 Fixed bad memory reference in ZOOM_record - cuased by member not being
477 initialized. This was a problem only in YAZ 3.0.12.
479 Fixed bug in conversion from MARC to XML: Non-XML characters in control
480 fields were not removed.
482 Changed the way C code is generated from codetables.xml. Made a MARC-8
483 conversion trie for each characterSet section rather than codeTable.
484 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
485 of codetables.xml from Larry Dixson, LOC. Bug #1464.
487 --- 3.0.12 2007/09/12
489 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
490 from ZOOM_record_error).
492 ZOOM C function ZOOM_record_get returns record schema for type="schema".
494 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
496 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
498 Better SRW-to-Bib-1 diagnostic mapping.
500 ZOOM C and yaz-client announces SRU version 1.2 by default.
502 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
505 Fixed in yaz_sru_decode to allow other version than 1.1.
507 --- 3.0.10 2007/08/22
509 Added support for SRU scan for ZOOM.
511 Added support for the use of the older versions or Extended Service
512 Update in ZOOM. To faciliate this, an option "updateVersion" may be
513 set to the version , 1=first, 2=second, 3=third. The third version is
514 what ZOOM C has used so far. And that, obviously, is the default.
516 Added support for CCL queries in Z39.50 queries sent to the GFS (and
517 therefore in Zebra and in SimpleServer-based applications). The new
518 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
519 qualifier file used to transform incoming CCL queries into Type-1 RPN,
520 which is passed into the back-end search callback function.
522 Added support for HTTP Basic authentication in clients: the SRU/W
523 codec encodes the username/password elements of the PDU structure
524 appropriately, and these may be set using the "user" and "password"
525 options in ZOOM-C applications (the same options that are used for
526 Z39.50 authentication).
530 Fixed bug #1208: SSL appears to be broken in ZOOM.
532 Fixed bug #1206: Libxml2 include path weirdness.
534 Added oid_name_to_dotstring.
536 Allow elementSetName to be specified for ZOOM C record update.
538 Allow waitAction to be specified for ZOOM C based for Extended Services.
540 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
541 syntax OID. Bug introduced in YAZ 3 series.
543 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
547 Fixed bug #1157: yaz-client does not read .yazclientrc from current
548 directory. yaz-client now reads commands from file given by option -f
549 if specified; then tries to read .yazclientrc in current directory.
550 Failing that, it reads .yazclientrc from user's home directory.
552 Added support for correlationInfo Note and ID for Record Update via
555 Added yaz-client command querycharset which specifies character set for
556 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
557 (termListAndStartPoint).
559 Charset ISO5428:1984 is an alias for ISO5428-1984.
561 Implemented a way to perform scan in a result set using Z39.50. This
562 is achieved by attaching the result set name in the characterInfo
563 (type InternationalString) of OtherInformation in the Scan Request PDU.
564 The result set is identified in the otherinformation by the new OID:
565 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
566 This allows for scan in result set and faceted search . Zebra did some
567 of this in the APT term using attribute type 8 and value being result
568 set. Using the OtherInformation approach for this is cleaner and easier
569 to work with in proxies and the like. This facility can be used in
570 yaz-client using new command setscan which takes a result set as first
571 argument, start position (APT) as second.
573 Changed decoding of SRU XML packed records to deal with servers that
574 have recordData with XML data with multiple root nodes. Also make
575 comparison for recordPacking case insensitive. Again, one server
576 returns "XML" where others return "xml".
578 For SRU responses allow Content-Type application/xml as well as text/xml.
582 Fixed bug in character set conversion of BER strings. Bug introduced
587 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
589 For OID class, use oid_class consistently.
591 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
594 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
595 character set for bibliographic information interchange". By Giannis Kosmas.
597 Added documentation on new OID API.
601 Changes to generic frontend server interface: added new member
602 'query_charset' for bend_initrequest structure. A backend init handler
603 should set this member to its native character set for query terms.
604 When defined, the frontend server logic will announce this character set
605 to a client if the negotiationModel bit is set by the client. All server
606 implementors are encouraged to specify this. If a backend server does not
607 specify this a warning is issued using yaz_log(YLOG_WARN,..).
609 Added CCL utility to remove terms (stop words) from resulting RPN
610 tree. This is handled by functions with prefix ccl_stop_words_ .
612 New ZOOM C option, "rpnCharset", which allows client-side conversion of
613 terms in RPN queries.
615 Clean-up the CCL API. Moved some internal structures from ccl.h to
616 private header cclp.h. Changed ccl_parser_create so that a Bibset must
617 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
618 This is replaced by ccl_parser_find_str which takes a string instead.
620 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
621 libyaz.la is the core of YAZ except the generic frontend server and
622 does not depend on POSIX threads anymore. libyaz_server.la is the
623 generic frontend server facilities and uses POSIX thread functionality
624 if available. The libyaz.la no longer depends on POSIX threads because
625 the number of global structures is limited. NMEM no longer re-uses blocks
626 between threads ; it simply free's memory immediately but allocates in
627 "large" chunks as usual. We don't expect any performance penalties
628 because of this. The yaz_log system is still using a global log_level so
629 caution must be taken when modifying it with yaz_log_init_.. +
630 yaz_log_mask_str. This, however, should not cause any trouble because
631 these functions are called during initialization of application code
632 anyway. `yaz-config --libs server` returns libs for server applications;
633 `yaz-config --libs` returns libs for non-server applications.
635 New OID database - with public definitions in oid_db.h. Removed old OID
636 database including the head oid.h and definitions such as enum oid_value
637 and struct oident. The new OID database uses the same string names as
638 before but the 'protocol' is gone. There are now only two representations
639 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
640 converts from string to OID; functions with prefix yaz_oid_to_string
641 converts the other way.
643 Change to emit_term() in CQL-to-PQF query translation: when a term has
644 the /regexp relation modifier, do not process it for leading and
645 trailing "^" and "*", which have quite different meanings in regular
648 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
649 write handlers no longer carries a 'last' parameter. This will make
650 yaz_iconv flush "less" characters. A flush is performed by call to
651 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
653 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
654 removed, because function yaz_query_to_wrbuf does the same.
656 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
657 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
659 Deprecated MARC utility functions removed.
661 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
664 Branch split: YAZ_2_1_55_branch
666 --- 2.1.54 2007/03/16
668 Fix to ZOOM-C so that transparent reconnection is properly handled on
669 connections that are in asynchronous mode.
671 Fixed compilation on OpenBSD 4.0.
673 Large strings in GRS-1 records are now properly displayed in yaz-client.
675 Added character conversion support for "advancegreek"; based on patch from
678 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
679 sequence is met. Before the error was not set so it would be unknown.
681 Adjust yaz-marcdump MARC reader so that it skips until record separator
684 --- 2.1.52 2007/03/07
686 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
687 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
688 fd_set structure used as a bitmask for the FDs to be selected on.
690 Using ACX_PTHREAD macro to check for POSIX threads.
692 Fixed have-vsnprintf check.
694 --- 2.1.50 2007/02/23
696 Fixes for configure on BSD. Bug #900.
698 Added snprintf/vsnprintf wrappers for systems that don't have
699 limits (heavens forbid).
701 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
702 created before all previous tasks were completed and removed from the
703 task queue, the new task could be removed by a mistake.
705 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
707 Implemented pass-through CQL-to-PQF conversions. Bug #861.
709 Fixed bug #832: Problem with MARC/charset in yaz-client.
711 Fixed bug #668: save command line history for yaz-client.
713 Fixed bug #830: pkg-config support.
715 --- 2.1.48 2007/01/23
717 Extended ZOOM result set options with two options that may be read by
718 a client: resultSetStatus and presentStatus with values as specified for
720 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
722 Fixed bug #827: Using SSL fails on Debian etch.
724 Fixed bug #826: Weird looking chars for set of MARC records.
726 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
727 that is treated as an ItemOrder with itemRequest being an XML document
728 external. The value of "doc" is the content.
730 Extended the GFS search facility. New member of bend_search_rr
731 'estimated_hit_count' signals that hits is known to be an estmate
732 (higher or lower than real hit count). New member 'partial_resultset'
733 signals that the search was partial (hit count is lower or equal than
734 real hit count). For Z39.50, the information is stored in resultSetStatus
735 member of SearchResponse APDU. For SRU, the information is signalled
736 via SRU diagnostic 59: "Result set created with valid partial results
739 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
741 --- 2.1.46 2007/01/13
743 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
745 Added ZOOM_connection_peek_event.
747 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
748 the following new functions:
749 ZOOM_event_nonblock, ZOOM_connection_process,
750 ZOOM_connection_get_{socket,mask,timeout},
751 ZOOM_connection_fire_event_{timeout,socket}.
752 The existing blocking event handler, ZOOM_event, is a wrapper for the
753 + blocking ZOOM_event_sys_{poll,select}.
755 Implemented function ccl_xml_config which parses XML version of CCL
756 configuration (bug #798).
758 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
760 Added timings utility (yaz/timing.h)
762 --- 2.1.44 2007/01/03
764 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
767 Fixed bug #779: Rotation of apdu.log fails.
769 Fixed for character set conversions:
770 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
771 Honor G1 set in MARC-8 decoding.
773 --- 2.1.42 2006/12/17
775 Fixed bug #775: char conversion does not handle Alternative UTF-8
778 Implemented function yaz_marc_read_line which parses MARC line format
779 records. There is a wealth of formats out there. So far, this function
780 reads line records produced by yaz_marc_write_line.
782 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
783 more generic and easier to remember(!) options: -i format and -o format
784 which specifies input format and output format respectively - where
785 format is one of "marc", "marcxml", "line", "marcxchange".
787 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
788 does not print anything except warnings for records.
790 For yaz-marcdump, added support for MARC split into files (-s) with a given
793 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
794 spec, at http://www.loc.gov/standards/sru/record-update/
795 This has changed the binary layout of the following structs:
796 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
797 bend_update_rr . Patch by Ko van der Sloot.
799 Added GFS utility function bend_assoc_is_alive which returns 1 if
800 association is still alive (client is connected); 0 otherwise (client
801 closed connection). This allows busy servers to stop working for
804 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
805 been a separate piece of software. This version of ziffy has been modified
806 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
808 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
810 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
811 Client code may now interrogate options such as "init_opt_sort" to
812 find out whether the server claims to support various options.
814 --- 2.1.40 2006/11/27
816 Added utilities yaz_{set,get}_esn to set/get element set name from
819 Removed the build of libyazthread.la. The libyaz.so is the threaded version
820 of YAZ and has been so since YAZ 2.1.10.
822 Implemented ZOOM_record_error which returns error information for
823 record (surrogate diagnostic).
825 --- 2.1.38 2006/10/31
827 Updates for SRU Update by Ko van der Sloot:
828 1. Changed name from "operation" to "action"
829 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
830 versions in the code, marked as 'backward compatible'.
831 3. Added diagnostics for SRU Update.
833 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
835 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
837 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
839 For GFS, fixed problem with SRU diagnostic 'First record position out of
840 range' being issued for 0 hits.
842 zoomtst10 part of Windows Build.
844 --- 2.1.36 2006/10/13
846 Implemented yaz_filepath_comp which splits a path into file path
847 components (required by Zebra 2.0.3+).
849 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
850 BSD inspired license until now so this should not have any real impact on
851 anybody. See http://www.opensource.org/licenses/bsd-license.php
853 Fixed bug #687: Missing log lines.
855 Fixed bug #678: CQL to PQF translation does not preserve double-quote
858 Fixed bug #689: SRU diagnostics to be added.
860 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
861 whether a connection is idle (no more work do do).
863 --- 2.1.34 2006/10/04
865 Change type of optval from long to int for invocation of setsockopt with
866 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
868 Added support for specifying the max log file size for the Generic
869 Frontend Server. The size is given with option -r.
871 --- 2.1.32 2006/09/21
873 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
875 --- 2.1.30 2006/09/17
877 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
880 Fixed bug in Generic Frontend Server that could cause a server to stop
881 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
883 For the generic frontend server, the maximum record size is used as maximum
884 size of incoming packages (SRU + Z39.50). The value until was previously
885 only used in Z39.50 Init negotiation and, later, in a session controlled
886 sizes of records returned. This is controlled using -k option. It can be
887 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
889 --- 2.1.28 2006/09/04
891 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
894 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
896 New option for yaz-marcdump -lpos=value which allows setting a portion
897 of MARC header to a certain value.
899 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
901 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
902 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
904 --- 2.1.26 2006/08/15
906 Fixed problem with SRU mode type (soap, get, post) for yaz-client
909 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
911 --- 2.1.24 2006/08/08
913 Fixed MARC ISO2709 encoding routines to deal with character set
916 Minor changes to GFS logging. Database included in search request log
919 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
920 cached/multiple records.
922 Shared libraries are built by default on Unix+configure.
924 Changed cql2pqf transformation to use a different evaluation order. The
925 new order is: always, relation, structure, position, truncation, index
926 and relationModifier. Old order was: always, relation, relationModifier,
927 structure, index, position, truncation. Note that the the latter ones
928 override former ones for identical attributes.. The new scheme means that
929 it is possible to override any existing attribute with a relationModifier.
930 And also that it is possible to override everything for the index rule
931 (except the ones listed in relationModifier). No order is perfect but this
932 one, we believe, covers more real cases.. The "always" should have been
933 called "default", since the attributes there can be overridden with all
936 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
937 compilation phase, but also for yaz-config --cflags output. This allows
938 us to have public headers with Libxml2 stuff in them . It should also,
939 eventually, make Libxml2 checks redundant in packages using YAZ, such
942 --- 2.1.22 2006/06/15
944 Changed SRU update structure bend_update_rr so that SRU diagnostics are
945 stored in uri, message and details.. Previously diagnostics were stored
946 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
947 compatibility.. but he's probably the only one affected, so.
949 Added support for CCL, compiled on the client side, in ZOOM-C. This
950 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
951 input; the resulting query objects can be used for for searching with
952 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
954 YAZ' configure searches for OpenSSL by default.
956 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
957 SL_CTX_use_certificate_file. See
958 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
959 for more info. Thanks to Ko van der Sloot.
961 --- 2.1.20 2006/06/02
963 Bug #600: SRU GET, POST support for yaz-client. Introduced
964 command 'sru' which selects method SOAP/GET/POST.
966 Allow missingValueAction to be specified for the sortspec string -
967 function yaz_sort_spec. By default, the missing value action is null.
968 Use ! to specify "abort". Use = followed by stringvalue to specify default
971 Ensured that Present-handler (if defined) is called in GFS before any call to
972 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
973 searchRetrieve requests.
975 Documentation for YAZ is now based on the Docbook XML/XSLT using
976 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
977 is no longer depending on jade/openjade or docbook-to-man scripts.
978 PDF is no longer part of the distribution - but can optionally be
979 made using DSSSL/jadetex or FOP.
981 Added retrieval handling support in Generic Frontend Server to support
982 conversion between MARC/XML as well as XSLTtransforms. See
983 etc/yazgfs.xml for an example.
985 Added Authentication support to Generic Frontend Server in SRU
986 mode. Authentication using HTTP Basic is supported, as is the use
987 of 'x-username' and 'x-password' parameters in the request itself.
989 Added support for a new character set MARC8s identical to MARC8 except
990 that it converts combined characters to single Unicode characters in the
991 Latin-1 range (when possible).
993 --- 2.1.18 2006/04/24
995 ASN.1 compiler 0.4: generates brief Doxygen file header for
996 generated .h/.c files.
998 Utility yaz_iconv now supports conversion to MARC-8.
1000 New facilities for the MARC module. The reading - and writing of
1001 content are separate methods for the yaz_marc_t handle. The following
1002 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1003 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1004 format). Write functions have prefix yaz_marc_write_.. The existing
1005 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1006 available. Removed support for OAI-MARC and simplexml (not the
1007 simplexml from PHP5).
1009 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1010 to be returned for this connection.
1012 --- 2.1.16 2006/03/31
1014 Allow multiple languages and charsets to be specified with
1015 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1016 negcharset iso-8859-1,utf-8
1018 Translation of proximity nodes from CQL into PQF now works.
1020 Moved to automake 1.8, 1.9.
1022 Added function yaz_log_set_handler which allows a log handler to be
1023 installed. This handler will be called for all log messages. Output
1024 to file is also produced; but that can be disabled by passing NULL
1025 fname to yaz_log_init_file.
1027 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1029 For SRW (including GFS), accept application/soap+xml as content-type
1032 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1033 produces NO stylesheet reference even if a default stylesheet is specified
1036 --- 2.1.14 2006/03/14
1038 Updated Windows package to include yazd.dll + yazd.lib for the
1039 Development component.
1041 If the environment variable YAZ_LOG is set, then it is used as a
1042 string indicating the default level of logging to use if not
1043 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1044 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1045 used as before. So, for example, to omit warnings from YAZ logging,
1046 export YAZ_LOG=-warn
1048 cql_transform() now map structure and other attributes before indexes,
1049 so that index-specific structures and other attributes can override
1050 defaults. So now a combination of mapping specifications such as:
1052 index.dc.date = 1=date-modified 4=5
1053 does the right thing.
1055 cql_transform() now also respects the "always" mapping specification,
1056 which establishes an initial set of attributes to be used for all
1057 terms except where overridden by more specific attributes associated
1058 with the index, relation or modifier.
1060 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1061 which mode to use; one of "post", "get" or "soap" (SRW, default).
1063 Fixes for yaz_iconv routines: changed trie-based character set conversions
1064 to use only non-negative values for bit fields due to Sun's C compiler not
1065 supporting negative values.
1067 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1068 sequences where not read correctly. Fix by Rustam Usmanov.
1070 Updated win/makefile to use options, settings which makes things
1071 compile with VS C 2005.
1073 --- 2.1.12 2006/02/01
1075 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1077 In ZOOM socket code, use select instead of poll on MacOSX.
1079 ZOOM-C now support client-side compilation of CQL into RPN that is
1080 sent to the server, enabling CQL to be used against all Z39.50
1081 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1082 ZOOM_query object, and submit it using ZOOM_connection_search().
1083 The CQL-to-RPN translation uses a configuration file, the name of
1084 which must be specified in the Connection's "cqlfile" option.
1086 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1087 function, which takes as its start-term parameter a ZOOM_query object
1088 (which may have had either CQL or RPN set into it).
1091 --- 2.1.10 2005/11/29
1093 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1094 GFS to support this as well. Backend handler, bend_srw_update, does the
1095 update work. Code contributed by Ko van der Sloot.
1097 Allow retrieval of Search Result-1 information in ZOOM by the use of
1098 options that are attached to a result set. ZOOM documentation updated
1101 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1102 UTF-8 conversion. Patch by Raj Patel.
1104 Added option -m to GFS to control formatting of timestamps in log file.
1106 Added 'exit' as synonym for 'quit' in yaz-client
1108 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1109 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1110 for the new members. Patch by Ko van der Sloot.
1112 Added support for SRU POST. It is supported for content-type
1113 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1115 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1116 Instead make the library libyaz.la multi-threaded. Threading as a whole
1117 can still be disabled by configure option --disable-threads. Previosly,
1118 with older GLIBCs there were problems with MT libs under Apache. This
1119 has now been fixed a long time ago.
1121 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1124 CQL module modified to be case insensitive for relations/indexes/operations.
1126 Fixed bug in CQL transform code: incorrect value relationModifieder
1129 Added 'show all' command for yaz-client which retrieves all results
1132 Added new yaz-client, xmles, which takes a (private) OID and
1133 a document to be sent as an extended service request.
1135 Describe new yaz-client commands wait_response and set_auto_wait.
1137 Increase TCP/IP listener backlog from 3 (which I am guessing was
1138 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1139 that the socket will queue as many incoming connections as it's able
1140 to handle ongoing connections. In other words, it will never now
1141 refuse a connection that it would be able to handle merely because
1142 it's not got around to accepting() enough of the pending connections
1143 yet. This is the behaviour anyway under Linux, where the listen()
1144 argument is ignored; but not under BSD and on systems such as
1145 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1146 YAZ-based servers should now be uniform across operating systems in
1149 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1150 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1151 This allows yaz-marcdump to read large MARC batches (>2 GB).
1153 Modified all YAZ source files - except the source which is auto-generated
1154 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1157 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1158 corresponding to the existing *_setl() function. These allow option
1159 values containing arbitrary valuues.
1161 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1162 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1163 except that it returns an indicator of whether or not the sort
1164 criterion was accepted (0 for OK, -1 for invalid).
1166 --- 2.1.8 2005/06/07
1168 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1169 MARC output rather than returning "new" buffer.
1171 yaz-client warns about unknown init options.
1173 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1175 --- 2.1.6 2005/05/24
1177 Added support for SRW sort in Generic Frontend Server. Patch
1178 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1179 sortKeys - or NULL if none is provided.
1181 Fixed bug #307: It was impossible to specify indefinite/no timeout
1182 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1185 Added support for multiple languages and charsets to be specified in
1186 ZOOM. Each charset/language is separated by a blank. If negotiation is
1187 in effect in init-response, Option
1188 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1189 Code based on patch by Vasiliy Osadchuk.
1191 Fixed bug #306: infinite recursion that occurred when calling
1192 yaz_log_level_init as the first call (before other log level or
1195 Fixed bug in scan handling in front end server: if preferred-Position-In-
1196 Response was non-present, a NULL pointer referece was performed.
1198 --- 2.1.4 2005/04/26
1200 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1201 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1202 now defined for all those error codes. So instead of putting 109 in
1203 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1204 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1206 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1209 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1211 Program yaz-client now exits and produces an error message if multiple
1212 Z39.50 servers are specified on the command line (none or one allowed
1215 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1218 --- 2.1.2 2005/03/16
1220 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1222 Fixed bug #272: Preserve spacing for CCL terms.
1224 --- 2.1.0 2005/03/14
1226 Added support for virtual hosts and multiple backend servers for
1227 the YAZ frontend server. The configution is XML based and
1228 support specificition of CQL to RPN mappings and explain information.
1229 See section "Virtual Hosts" in the YAZ manual.
1231 Extended OPAC display utility. OPAC display utility renders
1232 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1233 to supplement yaz_marc_decode_wrbuf.
1235 Fixed a bug in MARC decoder that could caused it to crash for some
1236 invalid MARC records. More diagnostics and warnings where added in
1237 XML output (warnings, etc are stored in comments).
1239 --- 2.0.34 2005/02/08
1241 Fixes for UNIX domain sockets. Bug #261.
1243 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1245 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1246 Added yaz_marc_subfield_str which defines subfield lead string which is
1247 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1248 yaz_marc_endline_str which defines end of fields string used in
1249 YAZ_MARC_LINE format. Default string is newline.
1251 Experimental support for MarcXChange. This format can be produced
1252 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1253 http://www.bs.dk/standards/MarcXchange.xsd
1255 Added yaz-client commands scansize that sets maximum number of
1256 entries to be returned by scan.
1258 --- 2.0.32 2005/01/11
1260 Added support for SRW scan in yaz-client and Generic Frontend Server.
1262 * Added whereInList member to SRW Scan Term.
1264 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1266 Fixed NMEM system to return aligned blocks on the smallest boundaries
1267 that are suitably aligned for all possible types on the particular
1268 architecture YAZ is being built for.
1270 --- 2.0.30 2005/01/04
1272 Fixed numerious warnings that was issued with newer versions of GCC.
1274 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1275 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1278 Make YAZ Generic Frontend Server slightly faster.
1280 Enhance (and reduce) logging for Generic Frontend Server.
1282 Revert YAZ log system so that it flushes every write operation
1283 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1285 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1286 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1287 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1288 will effectively disable old definitions.
1290 --- 2.0.28 2004/11/09
1292 Added yaz_log_time_format which specifies log format using
1295 Added yaz_log_module_level which returns mask for a module. Value
1296 is non-zero mask a if module is enabled; zero if disabled.
1298 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1299 in include/yaz/cql.h.
1301 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1303 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1305 Fixed bug #172: RPM builds does not enable SSL.
1307 Doxyfile.in part of dist. Doxyfile generated by configure.
1309 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1310 are given and the corresponding component does not exist.
1312 Extend CCL documentation in YAZ reference. Describe r=r.
1314 --- 2.0.26 2004/10/01
1316 Fixed MARC->MARCXML conversion to properly deal with
1317 fields, subfields, indicators having non-ASCII characters.
1319 Fixed MARC->MARCXML conversion so that ASCII control characters
1320 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1323 Added YAZ GFS support for conversion from Z39.50 surrogate
1324 diagnostics to SRW surrogate diagnostics.
1326 Bug fix: YAZ GFS did not return schema in explainResponse.
1328 --- 2.0.25 2004/09/30
1330 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1331 now converts recordSchema to elementSetName as well as schema URI.
1333 Fixed bug in COMSTACK that prevented HTTP request packages from being
1336 --- 2.0.24 2004/09/29
1338 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1339 does not require white-space before and after the dash in a range, e.g.
1340 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1343 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1344 due to new GCC removing "redundant" code.
1346 Added yaz-client commands scanpos and scanstep that sets preferred
1347 position and step-size for scan.
1349 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1351 Added CCL utility ccl_qual_buf which parses one or more CCL
1352 spec lines in a buffer.
1354 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1355 of name and value - ignoring empty lines and comments.
1357 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1359 Added odr_get_element_path which returns current element path for an
1360 ODR handle. This utility is useful in error handling or user-defined
1363 Added ODR_PRINT utility odr_set_stream which is is a more generic
1364 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1365 to a write function and pointer to close function. The close function - if
1366 non-NULL - will be called during odr_destroy.
1368 Fixed bug in CCL parser where truncation char was not removed from
1369 right side when truncation=both was in effect.
1371 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1374 --- 2.0.23 2004/08/11
1376 Fix buffer overrun in CQL parser when dealing with proximity (%).
1378 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1379 to UTF-8/UCS conversion is now only based on codetables.xml.
1381 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1383 --- 2.0.22 2004/08/06
1385 Add support for more "commit changes" in ZOOM (uses Extended Services).
1387 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1390 Yet another small fix for configure of SSL.
1392 --- 2.0.21 2004/05/14
1394 Fix SSL libs for configure when --with-openssl=DIR is given.
1396 --- 2.0.20 2004/05/10
1398 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1400 SSL comstack now uses yaz.pem certificate file on server side
1401 by default. Certificate filename can be configured by calling
1402 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1404 Fix bug regarding multiple calls to ZOOM_connection_connect.
1406 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1408 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1409 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1411 ZOOM now allows inspection of X509 peer certificate for verification.
1412 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1414 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1415 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1416 as "modular" but it simplifies things.
1418 Added cs_get_peer_certificate to that returns peer X509 PEM.
1420 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1421 NULL if SSL is unavailable.
1423 Documentation about MARC decoding tools.
1425 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1427 --- 2.0.19 2004/03/30
1429 Rename CHANGELOG to NEWS to follow GNU style packing.
1431 Fix bug with missing initialization of member in init_diagnostics.
1432 This bug affects threaded version of GFS server.
1434 --- 2.0.18 2004/03/20
1436 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1439 Ensure zlib.dll is packed with Windows install.
1441 --- 2.0.17 2004/03/17
1443 Fix encoding of xsd:string to use text instead of CDATA.
1445 Fix endless loop in CQL parser with unbalanced ".
1447 Use a more compact way to store MARC-8 conversion tables.
1449 --- 2.0.16 2004/03/16 Debian only
1451 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1454 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1459 --- 2.0.15 2004/03/01
1461 Another fix for decoding of XML packed records.
1463 --- 2.0.14 2004/02/25
1465 Fixes for Chunked encoding. White space not ignored after length spec.
1467 Update NS and use default NS for SRW diagnostic elements.
1469 --- 2.0.13 2004/02/23
1471 Implement ZOOM_resultset_cache_reset which resets record cache.
1473 Implement ZOOM_resultset_sort which sorts a result set.
1475 Implement chunked HTTP transfer.
1477 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1479 --- 2.0.12 2004/02/16
1481 Added member 'schema' to bend_explain_rr structure so that backend
1482 can specify explain record identifier. Defaults to Zeerex 2.0.
1484 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1486 --- 2.0.11 2004/02/16
1488 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1491 Added init command for yaz-client which sends "extra" init request.
1493 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1494 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1496 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1498 Make ZOOM error code for "invalid query".
1500 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1502 --- 2.0.10 2004/02/05
1504 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1507 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1509 Added option -p <file> to make Generic Frontend Server to write PID file.
1511 Added option -D to put Generic Frontend Server in background on its own.
1513 Make ZOOM C recognize option "password". If unset, "pass" is used
1514 (for backwards compatibility).
1516 Fixed a bug in Generic Frontend Server that could make it crash if a
1517 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1520 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1521 Must be issued before open, in order to be in effect.
1523 --- 2.0.9-6 2004/01/12 Debian/Windows
1525 Make the SRU server more picky WRT unknown params, etc.
1527 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1529 New YAZ client command, options, that sets Z39.50 options.
1531 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1532 options from a string of tokens (one token for each option bit).
1534 Update SRW diagnostic code messages.
1536 --- 2.0.9-5 2004/01/07 Debian/Windows
1538 Handle user defined stylesheet for SRW/SRU.
1540 --- 2.0.9-4 2004/01/06 Debian/Windows
1542 Fix bug in decoding of Content-Length.
1544 --- 2.0.9-3 2004/01/06 Debian/Windows
1546 Fix a bug with decoding of XML packed records.
1548 --- 2.0.9-2 2004/01/05 Debian only
1550 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1552 Fix bug in SRW/SRU diagnostics decoding.
1554 --- 2.0.9 2004/01/05
1556 Fixed bug in Generic Frontend Server which could drop records exceeding
1557 preferred message size. Reported and fixed by Irina Dijour.
1559 Fixed calculation of package size for structured records in Generic
1560 Frontend Server. Reported and fixed by Irina Dijour.
1562 Fixed namespace for SRW/SRU diagnostics.
1564 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1566 --- 2.0.8 2003/12/22
1568 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1569 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1572 CQL changes to reflect recent changes to the specification:
1573 * Documentation talks about context sets instead of index sets.
1574 * Documentation talks about indexes instead of qualifiers.
1575 * The CQL-to-PQF transformer's configuration file now uses
1576 "index.set.name = <attributes>" instead of the old form
1577 "qualifier.set.name = <attributes>". (Both forms are still
1578 understood but the latter is deprecated.)
1579 * CQL terms with no explicit index specified are now interpreted as
1580 cql.serverChoice instead of srw.serverChoice (which of course
1581 behaves exactly the same.)
1583 --- 2.0.7 2003/12/16
1585 MARC conversion can now generate ISO2709 output in another
1586 character set. yaz-marcdump uses this facility if you invoke it
1589 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1590 functions from there can be used from C++.
1592 --- 2.0.6 2003/12/04
1594 Frontend server now transfers memory from decoded packages to stream
1597 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1598 references to show up.
1600 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1601 the ZOOM Abstract API. The older names for the same options are still
1602 also supported for the benefit of old applications.
1604 ZOOM-C supports "implementationId" and "implementationVersion" options
1605 to go along with "implementationName". These allow the user code to
1606 specify identification strings to be sent to servers.
1607 Add OID for the new ExtLite attribute set.
1609 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1610 as requested/supplid by Ere Maijala <ere@atp.fi>
1612 For generic frontend server, reverse the order of
1613 "toolkit-supplied / application-supplied" strings sent as implementationId,
1614 Name and Version. Also, remove the spaces around the slash. This brings
1615 the GFS in line with the behaviour of ZOOM-C on the client side.
1617 Add function ZOOM_scanset_display_term.
1619 yaz-client shows scan displayTerm if present.
1621 Utility yaz-iconv is now installed by default along with the man page
1624 Extend configure check for OpenSSL to use pkg-config where available (such
1627 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1628 server to specify uid/gid/mask for socket using the format
1629 unix:[user=uid,][group=gid,][umask=mask,]file=path
1630 If file= is omitted the existing format is assumed, e.g.
1632 in which case the mask is 0666 (rw for everybody).
1634 Major restructure of YAZ source. All source in libyaz is in src directory.
1635 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1636 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1638 Added man page for utility yaz-marcdump (used to be called marcdump).
1639 yaz-marcdump is installed by 'make install'.
1641 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1642 of incoming package failed.
1644 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1646 Change prototype of odr_perror: add const to message string.
1648 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1650 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1651 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1652 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1653 DNS lookup. There should not be any compatibility problems with this
1654 assuming that blocking=1 or 0 is used.
1656 Fix bad reference in UNIX comstack in function cs_addrstr.
1658 Fix for compilation on AIX.
1660 The generic front-end server (server/seshigh.c) now supports returning
1661 Init diagnostics to the client in User-information-field, in
1662 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1665 --- 2.0.4 2003/09/04
1667 Allow any CQL relation (not just all,any,exact,scr).
1669 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1670 that features the same UI.
1672 Implemented command update0 in YAZ client which is equivalent to
1673 update but uses old of Ext Update ASN.1.
1675 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1676 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1677 Previously no OID was used for this info.
1679 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1680 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1681 returns 'malformed search term' otherwise.
1683 SortResponse member resultCount now set to NULL in sort handler of
1686 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1689 Add three new utility functions for translating OIDs between various
1690 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1691 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1692 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1693 char *oid_to_dotstring(const int *oid, char *oidbuf);
1694 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1696 Reverted modifications for ES Update definition for z_IU0Update
1697 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1698 is back to YAZ 2.0.2.
1700 String value attributes for CCL parser.
1702 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1703 which their FirstSearch server returns in Init responses, sometimes
1704 carrying useful diagnostic information when Init fails. This has the
1705 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1706 "z39.50/oclcui.asn", where its definition is somewhat different from
1707 what OCLC document on their web-site, as required to interoperate with
1710 Support for anonymous authentication in yaz-client. Use the command
1713 * Fix the OID of the Index Data-local "admin" Extended Service from
1714 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1715 the 1000, which indicates a locally-defined OID, was a mistake.
1717 --- 2.0.3 2003/06/20
1719 Fix CCL directive @case handling so that it affects string match for
1720 both CCL keywords and qualifiers.
1722 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1723 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1724 Decoder has been updated with ASN.1 changes as listed in
1725 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1726 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1727 z_IUUpdate, remains unchanged.
1729 ZOOM_record_get may now return a record in a specific character set.
1730 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1731 "from" is the character set of record as returned by target. "to" is
1732 the character set to be returned. If omitted, "to" is UTF-8.
1734 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1736 New ODR utility, odr_getelement, which returns name of element for
1737 which encoding/decoding failed.
1739 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1740 in cases where a required element was omitted.
1742 Bug fix: some MARC8 sequences were not converted.
1744 New ZOOM option "step" which specifies number of records to be
1745 retrieved in one chunk. Used in conjunction with "start" and "count".
1747 SRW support for yaz-client. Use scheme http: to use it, e.g.
1750 yaz-client no longer does (un)intelligent character set conversions
1751 by default. Can be enabled with charset and marc_charset commands.
1753 xmalloc trace fix for 64-bit systems such as DEC alpha.
1755 Solaris 2.6 compile fix.
1757 New function, cql_strerror() translates SRW error codes, as returned
1758 by cql_transform_error(), into human-readable English strings. Used
1759 in yaz-client diagnostics when appropriate.
1761 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1762 converts it into a type-1 query which is sent to the server. This
1763 makes CQL available for use with all Z-servers, as opposed to the tiny
1764 minority that can handle CQL queries themselves.
1766 --- 2.0.2 2003/04/28
1768 New Debian package layout similar to the Redhat Package layout.
1770 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1771 and search result respectively.
1773 --- 2.0.1 2003/04/25
1775 Redhat package is now several packages: libyaz (runtime libraries),
1776 libyaz-devel (development and documentation, and yaz (utility programs).
1777 Package spec file by Morten Bogeskov.
1779 New member 'schema' in struct bend_fetch_rr which the name of requested
1780 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1781 handler MAY set this to reflect the schema of the returned record.
1783 New member 'display_term' in struct scan_entry. GFS now sets member entries
1784 and allocates scan entries to be filled by user scan handler. In previous
1785 version, entries member was allocated by the scan handler. That still works,
1786 but the GFS will ignore member display_term - assuming it was NOT set by
1787 the handler. The fact that the GFS now allocates the entries both allows
1788 for new members and makes a scan handler easier to write.
1790 Fix CQL lex buffer overflow.
1792 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1793 SRU default recordPacking is string.
1795 SRU protocol support for frontend server.
1797 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1799 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1801 Added scan for the ZOOM shell (zoomsh).
1805 * String Identifers for Schemas (Amendment 5).
1806 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1807 Old definition for schema
1808 Odr_oid *schema; /* OPT */
1813 Z_InternationalString *uri;
1814 #define Z_Schema_oid 1
1815 #define Z_Schema_uri 2
1818 * resultCount parameter to Sort Response (Amendment 1).
1819 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1821 Support for SRW 1.0 over HTTP. This is an optional feature and
1822 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1825 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1826 on the same port. SRW SearchRetrieveRequests are mapped
1827 to bend_init,bend_search,bend_fetch,bend_close.
1829 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1831 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1832 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1834 ZOOM connections are SRW based if schem http is used for hostname
1835 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1836 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1838 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1839 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1840 distance=n, order=true/false, relation=le, prox unit=word. If
1841 n is omitted, distance 1 is used.
1843 Fixed problem with C compiler include path in wrong order.
1845 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1846 on Solaris. Patch from Ko van der Sloot.
1848 New MARC decode API. All new functions operate on a yaz_marc_t
1849 handle. The most important new functions are: yaz_marc_create,
1850 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1851 decode and destroy respectively. Decoder can produce formats
1852 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1853 include/yaz/marcdisp.h.
1855 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1856 to UTF-8, UCS-32, wchar_t or Latin-1.
1858 * Prototypes for yaz_iconv_-functions moved to separate header
1859 include/yaz/yaz-iconv.h.
1861 Make a few private functions 'static' in unix.c. This prevents
1862 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1864 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1865 are set when Init Response is received.
1867 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1868 but returns diagnostic set as well.
1870 New function yaz_strerror which is a portable wrapper for
1871 strerror/strerror_r/GetLastMessage.
1873 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1874 is returned for MARC. If type is "oai", then OAI MARC is returned.
1876 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1879 --- 1.9.2 2002/11/26
1881 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1883 Fix bad race conditions on SIGTERM and terminate gracefully in
1886 Move retrieval (data1) module to Zebra since nobody seems to be
1889 Add GRS-1 render for ZOOM using same format as yaz-client.
1891 --- 1.9.1 2002/10/05
1893 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1895 Fix broken ESpec handling in data1 module.
1897 SGML reader parses comments and makes them part of the data1 tree.
1899 Added several type casts so that YAZ compiles as C++ code.
1901 ZOOM didn't handle PDU encoding failures properly.
1903 Added more Bib-1 diagnostics (approved extensions).
1905 GNU configure: better check for iconv.
1907 More portable use of accept, getpeername. Check for socklen_t. Use
1908 int/size_t if socklen_t is not defined.
1912 PQF parser rejects bad queries - including those with extra
1913 characters in them. PQF parser used to silently ignore that.
1914 Cleaner API for PQF added, which allows you to get detailed
1915 error information for bad queries (see yaz/pquery.h).
1917 Fixed bug in ZOOM_record_get for type "database".
1919 Implemented mini iconv library supporting conversions between
1920 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1922 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1924 --- 1.8.9 2002/08/20
1926 Fixed ZOOM C record cache so that preferredRecordSyntax and
1927 elementSetName is used to check for already fetched records.
1929 --- 1.8.8 2002/08/02
1931 Added three members in bend_initrequest structure to facilitate
1932 character set negotiation.
1934 Fixed a bug in frontend server that could cause indefinite
1935 loops under rare conditions.
1937 Revised character set utilities (charneg.h) so that encoding
1938 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1940 For PQF, directive @term <type> sets term type for Scan/Search.
1941 Here <type> is general, string, numeric, null. The term type
1942 is inherited - just like @attr.
1944 New call odr_set_charset that sets character set conversion for
1945 international-strings on a ODR stream. Prototype is:
1946 int odr_set_charset(ODR o, const char *to, const char *from);
1947 The InternationalString is still represented as C string in YAZ
1948 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1949 won't). On the protocol level, you can use any encoding.
1951 Support for UNIX sockets in ZOOM.
1953 Solaris recv sometimes returns errno == ENOENT. It is treated as
1954 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1956 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1957 both client and server. Code by Morten Bogeskov.
1959 --- 1.8.7 2002/05/22
1961 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1962 that they can be used directly from Visual Basic. You must recompile
1963 your windows APP if you're using ZOOM.
1965 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1966 Commands "lang" and "charset" sets language and character set respectively.
1967 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1968 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1970 Attributes from multiple CCL fields may be OR'ed rather than merged
1971 using directive "@field or". Fields are still merged by default -
1972 equivalent to "@field merge".
1974 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1977 Fixed bug in zget for parameter ExtendedServicesResponse.
1981 --- 1.8.6 2002/03/25
1983 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1985 Client displays USR.1:SearchResult-1 (hits per term).
1987 Additional Search Info for search in Generic Frontend Server.
1989 Fixed CCL parsing of "field=s".
1991 WIN32 installer - using the excellent NSIS software from nullsoft.
1993 Fixed CCL parsing of "field = - <number>".
1995 Added function yaz_marc_decode that decodes MARC for line mode
1996 display or XML (similar to that used by JZKit).
1998 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1999 Z39.50. But ISO/ILL was, however.
2001 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2002 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

2005 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2007 --- 1.8.5 2002/02/03
2009 New YAZ client features: Command completion and new commands:
2010 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2011 Code provided by Jacob Poulsen.
2013 New call oid_trav, that visits all registered OIDs via callback.
2015 Function ZOOM_record_get now returns const char pointer rather than
2016 void pointer. It saves a lot of type casts.
2018 For YAZ client, command "auth" now allows you to set authentication
2019 in IdPass style. It is enabled when three tokens are given - order
2020 is user, group and password.
2022 Fix memory leaks in MARC record handling for ZOOM.
2024 New option for YAZ client, -k <kilobytes> that sets
2025 maximum record size. Similar to -k option for generic frontend
2026 server and yaz-ztest.
2028 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2030 Prefix query parser reports "fail" when bad attribute set is given.
2032 Fix in MARC decoder. Proximity logging. Fix for attribute set
2033 in scan handler for server. Patches by Shigeru Ishida.
2035 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2038 Configure option --with-openssl=<dir> now works when a directory is
2039 specified. Patch provided by Morten Bogeskov.
2041 New option for YAZ client, -u <auth>, that sets authentication.
2043 ZOOM fix: error information was sometimes "missing", since error
2044 was cleared/reset too when it shouldn't.
2046 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2048 --- 1.8.4 2002/01/04
2050 Scan for ZOOM API. New object ZOOM_scanset. New functions
2051 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2052 ZOOM_scanset_destroy.
2054 New ZOOM function, ZOOM_connection_last_event, that returns type
2055 of last event (such as "receive data", "send data", "apdu received",
2058 New ZOOM option, schema, that specifies schema for retrieval.
2060 New CCL feature. Qualifiers can be aliases for one or more
2061 other qualifiers (if more than one is given, OR is used).
2063 ZOOM uses named result sets if target supports it.
2065 Two new YAZ client commands: . (dot, which sources a script of YAZ
2066 client commands), and ! (to execute shell command.). Implemented
2069 Working on Debian packages.
2071 --- 1.8.3 2001/11/19
2073 YAZ client enables named result sets only if target supports it.
2075 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2077 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2078 with key="host" to get same result.
2080 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2081 Function Z3950_resultset_record(s) returns references to records
2082 "owned" by resultset. To become owner use Z3950_record_clone.
2084 Function z_ext_record handles Extended Services. Thanks to
2087 --- 1.8.2 2001/11/12
2089 CCL Parser fix: ignore token comma when dealing with and-lists.
2091 Documentation updates for COMSTACK.
2093 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2094 Changed prototype Z3950_records. For some functions, int parameters
2095 were changed to size_t.
2097 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2100 New MARC decode/display function, marc_display_exl, which properly rejects
2101 non-ISO2709 records. YAZ client uses it.
2103 --- 1.8.1 2001/10/29
2105 Fix bug: local attribute set wasn't set correctly in PQF strings.
2109 * Old Z39.50 codecs no longer supported.
2111 Added ZOOM C binding. See http://zoom.z3950.org/
2113 Renamed states for COMSTACKs to avoid confusion with events.
2115 Implemented cs_look and proper cs_rcvconnect.
2117 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2119 Configure detects POSIX threads on OpenBSD.
2121 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2122 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2124 When error is returned from present handler, non-surrogate diagnostic
2125 is returned in present response (and fetch handler is no longer called).
2127 * Minor adjustments to pquery parser (PQF). Token characters may be
2128 escaped by using backslash (C-style).
2130 PQF parser allows string attribute values to be specified. For @attr,
2131 non-numeric characters after the equal-sign are treated as strings
2132 (e.g. @attr 9=title).
2134 CCL trunction character may be defined (@truncation in file)
2136 * function zget_ExtendedServicesRequest sets waitAction to
2137 waitIfPossible (was wait).
2139 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2142 CCL operator names may be set in field definition files (CCL_bibset).
2143 See ccl/bib1 for an example.
2145 Fixes in ASN.1 compiler for C++ compatibility.
2147 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2148 and "op_or" to avoid conflict with C++.
2150 Fixed problem with GNU readline detection on Redhat 7.0.
2152 Added step-size for Scan backend handler.
2154 Fixed bug that made the frontend server crash when no attribute
2155 set was specified for scan.
2157 Front-end server automatically switches to original working directory
2158 when installed as an NT service. Previously -w had to be specified to
2161 Added extended attributes for retrieval module (data1), so that data1
2162 records carry d1_readXML/SGML attributes. d1_read also supports
2163 null-data rules ( <tag/>)
2165 On UNIX when POSIX threads are available, a separate library libyazthread
2166 is created. Programmers should link with that library and the yaz library
2167 when using threads. The reason for the split was that some applications
2168 on Linux, such as Apache, doesn't work well when using shared objects that
2171 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2172 (or any frontend server) in SSL mode by specifying ssl: followed by
2173 address. Only tested on UNIX.
2175 Added feature for CCL module. Virtual structure s=al or s=ol generates
2176 and-list and or-list respectively instead of phrase search.
2180 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2181 log_mask_str. This was done to avoid name conflicts with other libraries
2182 (such as other PHP extensions).
2184 Added raw OID member for preferred record syntax (request_format_raw)
2185 and returned record syntax (output_format_raw) for backend fetch method.
2187 Config file yaz-config now accepts options so that it returns specific
2188 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2190 Shared library support for UNIX using GNU libtool.
2192 * Modified backend interface. Request/Response struct's replaced by
2193 one read/write C struct. For example bend_fetchrequest and
2194 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2195 Every handler - even search has to be registered in bend_init
2196 handler. This means that the YAZ library no longer refers to
2197 external functions and it makes it possible to make the whole
2198 thing a single DLL/SO.
2200 Added Segment handler for backend server.
2202 Added Zmbol/Zebra administrative functions to YAZ client.
2204 Threaded frontend server on UNIX (when POSIX Threads are available).
2205 Starting the server with option -T enables multi-threading.
2209 Added configure option --enable-comp/disable-comp to control use
2210 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2211 located in sub directory asn.
2213 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2214 in ${exec_prefix}/bin along with the other programs yaz-client and
2217 GNU automake used to maintain makefiles.
2219 Added several OID's.
2221 Changed retrieval module so that we can load records with no abstract
2222 syntax defined. Tagpaths in these records are fully composed of string
2225 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2229 On UNIX, the generated makefile now supports a proper 'make install'.
2230 The prefix can be set via GNU configure to set the install location
2231 (default is /usr/local).
2233 * YAZ programs client and ztest were renamed to yaz-client and
2234 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2235 locations, such as /usr/bin,/usr/local/bin,etc.
2237 * YAZ Header files were moved from include to include/yaz. YAZ Header
2238 files are referred to as include <yaz/log.h> rather than <log.h>.
2239 The YAZ include path (-I ..) is therefore the same as before. Programmers
2240 should update their #include statements or use -Ipath/include/yaz
2241 instead. The main motivation for doing this change is that YAZ header files
2242 can be installed in "standard" locations /usr/include,/usr/local/include
2243 without introducing conflicts, since ALL YAZ header files are stored
2244 in subdirectory yaz (under /usr/include for example).
2246 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2247 rather than project/workspace files. We switched because project files
2248 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2251 Changed name of logging function, logf, to yaz_log, to prevent name
2252 clash with some math-log functions. The YAZ header log.h defines logf
2253 to yaz_log (#define) so there should be no incompatibilities by this
2256 Added bend_start/bend_stop handlers for server. These handler are
2257 called on start/stop of server. For windows they are called whenever
2258 a service is started/stopped.
2260 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2261 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2262 in util/yc.tcl. The auto-generated C code structures are, in a few
2263 cases, incompatible with the old decoders. There are differences in the
2264 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2265 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2266 The preprocessor variable ASN_COMPILED is defined when the compiled
2267 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2268 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2269 wish to use the old encoders/decoders you can specify --disable-yc
2272 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2273 version so that it supports both new - and old version of DB Update
2275 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2276 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2277 change. The name parameter can be set to 0 in which no name is specified
2278 for the construction. The macros odr_implicit and odr_explicit sets name
2279 parameter to zero for the construction involved. New macros
2280 odr_implicit_tag and odr_explicit_tag are similar to the others,
2281 except that a name parameter is added. For programmers' that don't use
2282 ODR they probably only need to change the call to z_APDU and z_External.
2284 Added access control facility by interfacing the TCP wrapper library.
2285 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2286 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2287 name of the daemon and enables the access control as specified in
2288 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2290 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2291 den Dool <H.M.vdnDool@kub.nl>.
2293 Added reference ID parameter to most functions in server API - refer
2294 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2296 Changed name of ccl library to libccl.a (was ccl.a).
2298 Fixed bug in decoder for Explain (Category TargetInfo).
2300 Added support for GNU readline in client. Thanks to Jacob Poulsen
2301 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2303 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2304 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2305 IMPLEMENTATION! This change was made to the development version before
2306 the ZIG decided to retract the amendment. If any users MUST be
2307 compatible with the original Update definition, PLEASE CONTACT US, and
2308 we will include a separate definition corresponding to the old Update
2309 ES. Note that because of the change to the ASN.1 of the
2310 TaskPackageRecordStructure we cannot define a single structure that
2311 will support both versions.
2313 * Added const modifier to buffer parameter for some ODR/BER encoding
2314 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2315 completeWAIS, odr_dumpBER.
2317 Fixed bug in client.c which caused a crash when a scanResponse didn't
2318 contain positionOfTerm.
2320 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2321 * will cause an error in a client if a non-YAZ target sends both a
2322 * list of Scan entries and non-surrogate diagnostics.
2324 Retrieval module enhancements. Tag sets may be typed in the reference
2325 to it. From the .abs-file the "tagset" directive takes a third optional
2326 integer type for the tag set referenced. From a .tag-file the "include"
2327 directive takes a third optional type as well. The old "type" directive
2328 in the tag set itself is still recognized but acts as the default type
2331 Backend interface change. Individual Scan terms returned from bend_scan
2332 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2333 in include/backend.h.
2335 Retrieval module enhancements. Multiple tag sets and attribute sets may
2336 be specified in abstract syntax specs. Revised the error/warning for
2337 logging messages reported by the retrieval module when reading the
2340 Object Identifier system (oid_..) changed. The API is backwards
2341 compatible but the oid-routines now allocates new OID's when needed.
2342 Raw OID's may be specified in oid_getvalbyname.
2344 YAZ now uses GNU configure to generate Makefile(s).
2346 * Minor changes in some of the member names of DeleteResultSetRequest and
2347 DeleteResultSetResponse. See include/proto.h.
2349 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2350 and added member 'languages' in TargetInfo (which was missing).
2352 Changed the way attribute sets are handled in the retrieval
2353 module. These are now cached, just like the abstract syntaxes
2356 Changed YAZ so that it links with compiled ASN.1.
2358 Added Explain-schema definitions and mapping routines. The following
2359 Explain categories have been implemented: AttributeDetails,
2360 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2362 Fixed minor bug in Windows version of Server Library.
2364 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2366 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2368 Added EXTERNAL: UNIverse Resource Report (non-standard).
2370 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2371 ENUMERATED and SET OF.
2373 * Added 'const' to some of the char pointer arguments for the
2374 functions, data1_read_node, data1_getelementbytagname,
2375 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2378 Fixed bug in data1_insert_taggeddata - the last_child member of
2379 parent wasn't initialised.
2381 * Changed data1_read_record and data1_read_node so that the supplied
2382 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2383 doesn't refer to any parts of the "SGML"-buffer.
2385 Fixed bug in server library (Windows version of statserv_remove).
2387 * Changed code so that it compiles as C++. The type definition
2388 of Odr_fun which is a member of Odr_arm was changed. The result is,
2389 that an explicit typecast is needed for the fun pointer when
2390 using Odr_arm - as in:
2391 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2393 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2395 Implemented the new structured date and time definition as approved
2396 by the ZIG. Added schemaId element to the specificTag in Espec-1
2397 (also approved at the last ZIG). Thanks to RVDM.
2399 Added some Object identifiers (RVDM).
2401 Changed the Update Extended Service (RVDM).
2403 Added command "refid" to client which specifies referenceId for
2404 the following requests.
2406 Implemented extended service handling for server. See ztest.c
2407 for an example as well as backend.h. New handlers are registerd
2408 in the Init handler.
2410 * Changed interface for sort in server.
2412 Added new members to statserv_options_block. It allows a server
2413 to read options from another source than just the command line. Thanks
2414 to Charles Woodfield.
2416 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2417 renamed to zboolean. Some C++ compilers complained about the name.
2419 Minor changes to gils.abs. Added index 's' (sort) on title
2420 and date/time-last-modified.
2422 --- 1.4pl2 1998/1/30
2424 Fixed bug in server library regarding inetd mode (-i). This bug
2425 was introduced by release 1.4.
2427 --- 1.4pl1 1998/1/29
2429 Added sort facility in client and backend server interface.
2431 Fixed problem with dependencies in Makefile(s).
2433 Fixed bugs for encoders/decoders of extended services and
2436 Implemented sub-tree feature for schemas. Sub-trees are
2437 referenced in *.abs-files. See explain.abs for an example
2438 of the use of this feature.
2440 Modified bib1.att; local attributes for ANY didn't include
2441 ANY itself (only affects use of the retrieval module).
2443 Fixed bug in plain SGML reader in function data1_read_node:
2444 tags with prefix "var" was incorrectly interpreted as variants.
2446 Added feature "sub-schemas" to enable references to - and definitions
2447 of - group of elements.
2449 * Removed member parent from type data1_element (in data1.h).
2451 Implemented function odr_nullval() that returns the value of
2454 * Removed member num_children from data1_node (in data1.h).
2456 Made NT service interface part of the server library. The
2457 function statserv_main uses the NT service when required and
2458 calls the statserv_start / statserv_close routines.
2460 Routine zget_SearchRequest and zget_PresentRequest fills
2461 resultSetName/Id member with "default" instead of "Default".
2463 Fixed memory leak in server. Request queue member wasn't freed.
2465 Fixed nmem_exit so that memory is freed.
2469 Revised the CCL parser utility to be thread safe.
2471 Added function, oid_ent_to_oid, to replace the function
2472 oid_getoidbyent, which is not thread safe.
2474 * Added nmem_init and nmem_exit to initialize and release
2475 NMEM resources. Function nmem_init should be called once in the
2476 initial thread before NMEM/ODR is used. statserv.c and client.c
2477 have been changed accordingly. The change was necessary to make
2478 NMEM thread safe. The NMEM memory pool is shared amongst threads
2479 in a process. Unix-based applications will still work fine without
2482 Added NT Services interface for the the Z39.50 (statserv) Server.
2483 Refer to the ztest.c source on the usage.
2485 Windows 95/NT port using MSVC5.0. Project files are included in the
2488 * Defined new 'global' handle for the retrieval (data1) system. The
2489 new handled, data1_handle, describes the state of the data1 system.
2490 This handle is passed as first argument to virtually all
2491 data1 related routines. The functions data1_create and data1_destroy
2492 creates and destroys a data1 handle respectively.
2494 Added ODR encode stream member to all backend request structures
2495 init, search, scan etc. This stream should be used to allocate all
2496 memory used for the response when thread safe operation is needed.
2498 Changed the comstack utility, cs_addstr, to be thread safe. The
2499 returned hostname string returned by the function is now part the
2502 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2503 function. The cs_straddr takes a COMSTACK handle as argument, so this
2504 function must be used after cs_create and before bind/connect.
2505 This function is thread safe.
2507 Moved test server to 'ztest' directory - generic server code still
2508 in 'server' directory.
2510 Made prefix query (pquery.c) utility thread safe.
2512 Added new function modifier YAZ_EXPORT to 'export' public DLL
2513 functions when using windows (see include/yconfig.h).
2515 Added definitions to the OID database (util/oid.c) (RVDM).
2517 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2519 Added call to ccl_rpn_delete in client program.
2521 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2522 release of RPN structure.
2524 Added support for C++, headers uses extern "C" for public definitions.
2525 With input from RVDM.
2527 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2528 Thanks to Ronald van der Meer (RVDM).
2530 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2532 Added support for private extensions to the OID database
2533 (oid_setprivateoids()). Thanks to RVDM.
2535 Added optional, physical ANY (key replication)
2537 Fixed null-reference problem in GRS-1 output filter.
2539 Proximity operator added to Prefix Query Format (PQF).
2541 In test client command "base" accepts multiple databases.
2543 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2547 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2549 Smallish bug-fixes in the new encoders/decoders (explain).
2551 Bug fixed in DeleteRequest.
2553 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2555 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2557 Added SOIF syntax (using private OID for now) to retrieval module and client.
2559 Added Update extended service.
2561 Added SearchResult-1 additional info structure.
2563 Added optional CCL (ISO8777) interpreter as separate module. Available
2566 --- 1.2 1996/6/10 (1st anniversary release)
2568 Added Summary record syntax. Lightly tested.
2570 Added OPAC record syntax. Untested.
2572 Added ResourceReport service encoders/decoders. Untested.
2574 Fixed bug in z_Unit - wrong tagging on unitSystem.
2576 Fixed bug in the DiagRecs decoder.
2578 Added options for max PDU size and session timeout to frontend-server.
2580 Added documentation of query-language parsers and other supporting utilities.
2582 [frontend-server] Added Attribute set to the bend_scanrequest API.
2584 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2585 surrogate diagnostics were generated.
2587 [retrieval] Allow multiple local values for attribute.
2589 [retrieval] Allow multiple attributes per element in .abs files. index type.
2591 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2593 --- 1.1pl2 1996/4/10
2595 Minor changes, mostly specific to Zebra's requirements (retrieval)
2599 Repaired bug in frontend server when running multiple listening
2600 endpoints in dynamic mode.
2602 z_External() now won't break if a known, ASN.1 value comes encapsulated
2603 in an octet-string. The value will pass through unmodified in an Odr_oct.
2605 Added a bit of code to the demo client to decode & display
2606 ASN.1-structured records represented in the octet-aligned branch of
2607 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2609 Added z_ext_getentbyref() to the ASN module. Doc updated.
2611 * Completed the SCAN definition in the ASN module. This may break SCAN
2612 code based on older YAZ-versions at compile-time. The fix is easy -
2615 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2616 under the SCAN definition. Remember to initialize this, server-people.
2618 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2619 that this does not extend to ODR and ASN.
2621 Comstack allows insertion of established socket (primarily for
2622 inetd-operation of servers). Doc updated.
2624 Front-end server can now start from the inetd in TCP mode. Doc
2627 --- 1.0pl4 1996/1/24
2631 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2632 the rank and record number.
2634 Adjustments to the frontend server.
2636 Fixed diagnostic BER dumper. It ignored the file argument.
2640 Various changes to retrieval module.
2642 Changed the union discriminators of the protocol files from enums to
2643 ints paired with #defines.
2645 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2648 *Changed operator in the RPN structure to 'roperator', again to avoid a
2651 Fixed problems in Explain decoders/encoders.
2653 --- 1.0pl2 1995/12/6
2655 Memory bug in log module fixed.
2657 --- 1.0pl1 1995/12/5
2659 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2661 Bug in Explain DatabaseInfo module fixed.
2663 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2667 The shift to v1.0 signals that we now consider the *core* functionality
2668 of YAZ reasonably stable (the core being more or less equivalent to
2669 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2670 tested (Explain not at all - though that will happen soonish).
2672 Minor changes to code to support Windows port.
2674 Various minor changes after we're getting to use GRS-1 & co. more.
2676 Added Espec-1 format.
2678 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2679 of the protocol and it cannot be selected when encoding (maps into 'string'
2680 when decoding). Needed to talk to some servers.
2682 Demo client can request simple element set names.
2684 Added Diagnostic Format encoders/decoders.
2686 Added simple Close handling to frontend server (no hooks for resource
2687 reporting yet), and demonstration client.
2689 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2691 --- 1.0b3 1995/08/24
2693 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2694 handled incorrectly when records were requested in the searchResponse. This
2695 will only affect you if you use the frontend-server.
2697 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2698 Test-client will ask for and print GRS1. Ztest will return dummy records
2701 Added Explain encoders/decoders to the service-level API. Untested.
2703 Added Extended Services: Item Order encoders and decoders to the Service-
2704 level API. Untested. We could use a recent copy of the pertinent bits
2705 of the ILL protocol to add those bits.
2707 Added diagnostic format 1 encoders/decoders to the service-level API.
2710 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2711 odr_cons.c, which causes a more correct output.
2713 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2714 was always set to 0 when no records were requested in the searchRequest.
2716 * Added better external-handling. This shouldn't harm old code that
2717 *encodes* externals. It can break code that looks for a
2718 'single-ASN1-type' representation, since those types that are known
2719 are now decoded immediately. Look at the SUTRS sample code in
2720 seshigh.c and client.c. Documentation updated.
2722 Handling of structured records in bend_fetchresponse. Length -1 marks
2723 structured record, type is deduced from format field.
2725 --- 1.0b2 1995/06/27
2726 Fairly quick maintenance release to add SUTRS support.
2728 Fixed handling of SUTRS records in the demonstration client.
2730 * Added format field to the bend_fetchrequest and bend_fetchresponce
2731 structures of the backend API (frontend server). When the record is
2732 returned, the value of the format field is mapped to an OID. The
2733 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2734 of the record. The special value VAL_NONE in the bend_request means
2735 that no specific format was requested by the client. Documentation
2736 updated accordingly. Test server (ztest) will return a fixed dummy
2737 SUTRS record if your client requests SUTRS.
2739 Documentation updated accordingly.
2741 You can now set external libraries and RANLIB support in the top-level
2745 First public release.
