1 Added support for a new character set MARC8s identical to MARC8 except
2 that it converts combined characters to single Unicode characters in the
3 Latin-1 range (when possible).
7 ASN.1 compiler 0.4: generates brief Doxygen file header for
10 Utility yaz_iconv now supports conversion to MARC-8.
12 New facilities for the MARC module. The reading - and writing of
13 content are separate methods for the yaz_marc_t handle. The following
14 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
15 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
16 format). Write functions have prefix yaz_marc_write_.. The existing
17 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
18 available. Removed support for OAI-MARC and simplexml (not the
21 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
22 to be returned for this connection.
26 Allow multiple languages and charsets to be specified with
27 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
28 negcharset iso-8859-1,utf-8
30 Translation of proximity nodes from CQL into PQF now works.
32 Moved to automake 1.8, 1.9.
34 Added function yaz_log_set_handler which allows a log handler to be
35 installed. This handler will be called for all log messages. Output
36 to file is also produced; but that can be disabled by passing NULL
37 fname to yaz_log_init_file.
39 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
41 For SRW (including GFS), accept application/soap+xml as content-type
44 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
45 produces NO stylesheet reference even if a default stylesheet is specified
50 Updated Windows package to include yazd.dll + yazd.lib for the
51 Development component.
53 If the environment variable YAZ_LOG is set, then it is used as a
54 string indicating the default level of logging to use if not
55 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
56 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
57 used as before. So, for example, to omit warnings from YAZ logging,
60 cql_transform() now map structure and other attributes before indexes,
61 so that index-specific structures and other attributes can override
62 defaults. So now a combination of mapping specifications such as:
64 index.dc.date = 1=date-modified 4=5
67 cql_transform() now also respects the "always" mapping specification,
68 which establishes an initial set of attributes to be used for all
69 terms except where overridden by more specific attributes associated
70 with the index, relation or modifier.
72 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
73 which mode to use; one of "post", "get" or "soap" (SRW, default).
75 Fixes for yaz_iconv routines: changed trie-based character set conversions
76 to use only non-negative values for bit fields due to Sun's C compiler not
77 supporting negative values.
79 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
80 sequences where not read correctly. Fix by Rustam Usmanov.
82 Updated win/makefile to use options, settings which makes things
83 compile with VS C 2005.
87 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
89 In ZOOM socket code, use select instead of poll on MacOSX.
91 ZOOM-C now support client-side compilation of CQL into RPN that is
92 sent to the server, enabling CQL to be used against all Z39.50
93 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
94 ZOOM_query object, and submit it using ZOOM_connection_search().
95 The CQL-to-RPN translation uses a configuration file, the name of
96 which must be specified in the Connection's "cqlfile" option.
98 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
99 function, which takes as its start-term parameter a ZOOM_query object
100 (which may have had either CQL or RPN set into it).
103 --- 2.1.10 2005/11/29
105 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
106 GFS to support this as well. Backend handler, bend_srw_update, does the
107 update work. Code contributed by Ko van der Sloot.
109 Allow retrieval of Search Result-1 information in ZOOM by the use of
110 options that are attached to a result set. ZOOM documentation updated
113 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
114 UTF-8 conversion. Patch by Raj Patel.
116 Added option -m to GFS to control formatting of timestamps in log file.
118 Added 'exit' as synonym for 'quit' in yaz-client
120 Added support for specifying SRW resultSetId + resultSetIdleTime in a
121 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
122 for the new members. Patch by Ko van der Sloot.
124 Added support for SRU POST. It is supported for content-type
125 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
127 Do not build the separate Multi-threaded (MT) library libyazthread.la.
128 Instead make the library libyaz.la multi-threaded. Threading as a whole
129 can still be disabled by configure option --disable-threads. Previosly,
130 with older GLIBCs there were problems with MT libs under Apache. This
131 has now been fixed a long time ago.
133 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
136 CQL module modified to be case insensitive for relations/indexes/operations.
138 Fixed bug in CQL transform code: incorrect value relationModifieder
141 Added 'show all' command for yaz-client which retrieves all results
144 Added new yaz-client, xmles, which takes a (private) OID and
145 a document to be sent as an extended service request.
147 Describe new yaz-client commands wait_response and set_auto_wait.
149 Increase TCP/IP listener backlog from 3 (which I am guessing was
150 copied from the SunOS manual entry way back when) so SOMAXCONN, so
151 that the socket will queue as many incoming connections as it's able
152 to handle ongoing connections. In other words, it will never now
153 refuse a connection that it would be able to handle merely because
154 it's not got around to accepting() enough of the pending connections
155 yet. This is the behaviour anyway under Linux, where the listen()
156 argument is ignored; but not under BSD and on systems such as
157 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
158 YAZ-based servers should now be uniform across operating systems in
161 yaz-marcdump uses 64-bit file access on some systems. This is enabled
162 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
163 This allows yaz-marcdump to read large MARC batches (>2 GB).
165 Modified all YAZ source files - except the source which is auto-generated
166 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
169 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
170 corresponding to the existing *_setl() function. These allow option
171 values containing arbitrary valuues.
173 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
174 ZOOM_resultset_sort() in new applications. Its behaviour is identical
175 except that it returns an indicator of whether or not the sort
176 criterion was accepted (0 for OK, -1 for invalid).
180 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
181 MARC output rather than returning "new" buffer.
183 yaz-client warns about unknown init options.
185 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
189 Added support for SRW sort in Generic Frontend Server. Patch
190 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
191 sortKeys - or NULL if none is provided.
193 Fixed bug #307: It was impossible to specify indefinite/no timeout
194 for ZOOM_event. Special timeout value -1 now means indefinite timeout
197 Added support for multiple languages and charsets to be specified in
198 ZOOM. Each charset/language is separated by a blank. If negotiation is
199 in effect in init-response, Option
200 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
201 Code based on patch by Vasiliy Osadchuk.
203 Fixed bug #306: infinite recursion that occurred when calling
204 yaz_log_level_init as the first call (before other log level or
207 Fixed bug in scan handling in front end server: if preferred-Position-In-
208 Response was non-present, a NULL pointer referece was performed.
212 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
213 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
214 now defined for all those error codes. So instead of putting 109 in
215 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
216 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
218 Modified the yaz-marcdump utility to skip garbage bytes between MARC
221 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
223 Program yaz-client now exits and produces an error message if multiple
224 Z39.50 servers are specified on the command line (none or one allowed
227 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
232 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
234 Fixed bug #272: Preserve spacing for CCL terms.
238 Added support for virtual hosts and multiple backend servers for
239 the YAZ frontend server. The configution is XML based and
240 support specificition of CQL to RPN mappings and explain information.
241 See section "Virtual Hosts" in the YAZ manual.
243 Extended OPAC display utility. OPAC display utility renders
244 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
245 to supplement yaz_marc_decode_wrbuf.
247 Fixed a bug in MARC decoder that could caused it to crash for some
248 invalid MARC records. More diagnostics and warnings where added in
249 XML output (warnings, etc are stored in comments).
251 --- 2.0.34 2005/02/08
253 Fixes for UNIX domain sockets. Bug #261.
255 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
257 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
258 Added yaz_marc_subfield_str which defines subfield lead string which is
259 used in YAZ_MARC_LINE format. Default string is blank+$. Added
260 yaz_marc_endline_str which defines end of fields string used in
261 YAZ_MARC_LINE format. Default string is newline.
263 Experimental support for MarcXChange. This format can be produced
264 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
265 http://www.bs.dk/standards/MarcXchange.xsd
267 Added yaz-client commands scansize that sets maximum number of
268 entries to be returned by scan.
270 --- 2.0.32 2005/01/11
272 Added support for SRW scan in yaz-client and Generic Frontend Server.
274 * Added whereInList member to SRW Scan Term.
276 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
278 Fixed NMEM system to return aligned blocks on the smallest boundaries
279 that are suitably aligned for all possible types on the particular
280 architecture YAZ is being built for.
282 --- 2.0.30 2005/01/04
284 Fixed numerious warnings that was issued with newer versions of GCC.
286 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
287 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
290 Make YAZ Generic Frontend Server slightly faster.
292 Enhance (and reduce) logging for Generic Frontend Server.
294 Revert YAZ log system so that it flushes every write operation
295 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
297 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
298 instead of LOG_, due to name clash with syslog(3). LOG_ are still
299 present. New applications should define YAZ_USE_NEW_LOG=1 - this
300 will effectively disable old definitions.
302 --- 2.0.28 2004/11/09
304 Added yaz_log_time_format which specifies log format using
307 Added yaz_log_module_level which returns mask for a module. Value
308 is non-zero mask a if module is enabled; zero if disabled.
310 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
311 in include/yaz/cql.h.
313 Fixed bug #176: Dont throw diagnostics on empty SRU args.
315 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
317 Fixed bug #172: RPM builds does not enable SSL.
319 Doxyfile.in part of dist. Doxyfile generated by configure.
321 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
322 are given and the corresponding component does not exist.
324 Extend CCL documentation in YAZ reference. Describe r=r.
326 --- 2.0.26 2004/10/01
328 Fixed MARC->MARCXML conversion to properly deal with
329 fields, subfields, indicators having non-ASCII characters.
331 Fixed MARC->MARCXML conversion so that ASCII control characters
332 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
335 Added YAZ GFS support for conversion from Z39.50 surrogate
336 diagnostics to SRW surrogate diagnostics.
338 Bug fix: YAZ GFS did not return schema in explainResponse.
340 --- 2.0.25 2004/09/30
342 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
343 now converts recordSchema to elementSetName as well as schema URI.
345 Fixed bug in COMSTACK that prevented HTTP request packages from being
348 --- 2.0.24 2004/09/29
350 Added CCL facility r=r "range" which is similar to r=o "ordered" but
351 does not require white-space before and after the dash in a range, e.g.
352 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
355 Fixed a few AC_TRY_LINK configure tests that did not operate properly
356 due to new GCC removing "redundant" code.
358 Added yaz-client commands scanpos and scanstep that sets preferred
359 position and step-size for scan.
361 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
363 Added CCL utility ccl_qual_buf which parses one or more CCL
364 spec lines in a buffer.
366 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
367 of name and value - ignoring empty lines and comments.
369 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
371 Added odr_get_element_path which returns current element path for an
372 ODR handle. This utility is useful in error handling or user-defined
375 Added ODR_PRINT utility odr_set_stream which is is a more generic
376 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
377 to a write function and pointer to close function. The close function - if
378 non-NULL - will be called during odr_destroy.
380 Fixed bug in CCL parser where truncation char was not removed from
381 right side when truncation=both was in effect.
383 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
386 --- 2.0.23 2004/08/11
388 Fix buffer overrun in CQL parser when dealing with proximity (%).
390 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
391 to UTF-8/UCS conversion is now only based on codetables.xml.
393 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
395 --- 2.0.22 2004/08/06
397 Add support for more "commit changes" in ZOOM (uses Extended Services).
399 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
402 Yet another small fix for configure of SSL.
404 --- 2.0.21 2004/05/14
406 Fix SSL libs for configure when --with-openssl=DIR is given.
408 --- 2.0.20 2004/05/10
410 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
412 SSL comstack now uses yaz.pem certificate file on server side
413 by default. Certificate filename can be configured by calling
414 comstack function cs_set_ssl_certificate_file before cs_bind is used.
416 Fix bug regarding multiple calls to ZOOM_connection_connect.
418 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
420 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
421 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
423 ZOOM now allows inspection of X509 peer certificate for verification.
424 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
426 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
427 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
428 as "modular" but it simplifies things.
430 Added cs_get_peer_certificate to that returns peer X509 PEM.
432 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
433 NULL if SSL is unavailable.
435 Documentation about MARC decoding tools.
437 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
439 --- 2.0.19 2004/03/30
441 Rename CHANGELOG to NEWS to follow GNU style packing.
443 Fix bug with missing initialization of member in init_diagnostics.
444 This bug affects threaded version of GFS server.
446 --- 2.0.18 2004/03/20
448 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
451 Ensure zlib.dll is packed with Windows install.
453 --- 2.0.17 2004/03/17
455 Fix encoding of xsd:string to use text instead of CDATA.
457 Fix endless loop in CQL parser with unbalanced ".
459 Use a more compact way to store MARC-8 conversion tables.
461 --- 2.0.16 2004/03/16 Debian only
463 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
466 Update CQL parser to use new CQL 1.1 modifiers for booleans and
471 --- 2.0.15 2004/03/01
473 Another fix for decoding of XML packed records.
475 --- 2.0.14 2004/02/25
477 Fixes for Chunked encoding. White space not ignored after length spec.
479 Update NS and use default NS for SRW diagnostic elements.
481 --- 2.0.13 2004/02/23
483 Implement ZOOM_resultset_cache_reset which resets record cache.
485 Implement ZOOM_resultset_sort which sorts a result set.
487 Implement chunked HTTP transfer.
489 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
491 --- 2.0.12 2004/02/16
493 Added member 'schema' to bend_explain_rr structure so that backend
494 can specify explain record identifier. Defaults to Zeerex 2.0.
496 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
498 --- 2.0.11 2004/02/16
500 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
503 Added init command for yaz-client which sends "extra" init request.
505 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
506 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
508 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
510 Make ZOOM error code for "invalid query".
512 Fixed compilation for SSL which wasn't properly enabled for all platforms.
514 --- 2.0.10 2004/02/05
516 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
519 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
521 Added option -p <file> to make Generic Frontend Server to write PID file.
523 Added option -D to put Generic Frontend Server in background on its own.
525 Make ZOOM C recognize option "password". If unset, "pass" is used
526 (for backwards compatibility).
528 Fixed a bug in Generic Frontend Server that could make it crash if a
529 client sets characterSetNegotation bit, but didn't pass negotiation stuff
532 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
533 Must be issued before open, in order to be in effect.
535 --- 2.0.9-6 2004/01/12 Debian/Windows
537 Make the SRU server more picky WRT unknown params, etc.
539 Bug fix: ZOOM scan response didn't return displayTerm - when present.
541 New YAZ client command, options, that sets Z39.50 options.
543 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
544 options from a string of tokens (one token for each option bit).
546 Update SRW diagnostic code messages.
548 --- 2.0.9-5 2004/01/07 Debian/Windows
550 Handle user defined stylesheet for SRW/SRU.
552 --- 2.0.9-4 2004/01/06 Debian/Windows
554 Fix bug in decoding of Content-Length.
556 --- 2.0.9-3 2004/01/06 Debian/Windows
558 Fix a bug with decoding of XML packed records.
560 --- 2.0.9-2 2004/01/05 Debian only
562 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
564 Fix bug in SRW/SRU diagnostics decoding.
568 Fixed bug in Generic Frontend Server which could drop records exceeding
569 preferred message size. Reported and fixed by Irina Dijour.
571 Fixed calculation of package size for structured records in Generic
572 Frontend Server. Reported and fixed by Irina Dijour.
574 Fixed namespace for SRW/SRU diagnostics.
576 Fixed SEGV in yaz-client that occured for HTTP connection errors.
580 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
581 this version is incompatible with version 1.0 and older YAZ SRW/SRU
584 CQL changes to reflect recent changes to the specification:
585 * Documentation talks about context sets instead of index sets.
586 * Documentation talks about indexes instead of qualifiers.
587 * The CQL-to-PQF transformer's configuration file now uses
588 "index.set.name = <attributes>" instead of the old form
589 "qualifier.set.name = <attributes>". (Both forms are still
590 understood but the latter is deprecated.)
591 * CQL terms with no explicit index specified are now interpreted as
592 cql.serverChoice instead of srw.serverChoice (which of course
593 behaves exactly the same.)
597 MARC conversion can now generate ISO2709 output in another
598 character set. yaz-marcdump uses this facility if you invoke it
601 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
602 functions from there can be used from C++.
606 Frontend server now transfers memory from decoded packages to stream
609 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
610 references to show up.
612 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
613 the ZOOM Abstract API. The older names for the same options are still
614 also supported for the benefit of old applications.
616 ZOOM-C supports "implementationId" and "implementationVersion" options
617 to go along with "implementationName". These allow the user code to
618 specify identification strings to be sent to servers.
619 Add OID for the new ExtLite attribute set.
621 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
622 as requested/supplid by Ere Maijala <ere@atp.fi>
624 For generic frontend server, reverse the order of
625 "toolkit-supplied / application-supplied" strings sent as implementationId,
626 Name and Version. Also, remove the spaces around the slash. This brings
627 the GFS in line with the behaviour of ZOOM-C on the client side.
629 Add function ZOOM_scanset_display_term.
631 yaz-client shows scan displayTerm if present.
633 Utility yaz-iconv is now installed by default along with the man page
636 Extend configure check for OpenSSL to use pkg-config where available (such
639 Incorporate patch by Morten Bogeskov which allows a Unix file socket
640 server to specify uid/gid/mask for socket using the format
641 unix:[user=uid,][group=gid,][umask=mask,]file=path
642 If file= is omitted the existing format is assumed, e.g.
644 in which case the mask is 0666 (rw for everybody).
646 Major restructure of YAZ source. All source in libyaz is in src directory.
647 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
648 util (utility programs such as ASN.1 compiler, yaz-marcdump).
650 Added man page for utility yaz-marcdump (used to be called marcdump).
651 yaz-marcdump is installed by 'make install'.
653 Fixed a memory leak in Generic Frontend Server that occurred when decoding
654 of incoming package failed.
656 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
658 Change prototype of odr_perror: add const to message string.
660 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
662 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
663 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
664 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
665 DNS lookup. There should not be any compatibility problems with this
666 assuming that blocking=1 or 0 is used.
668 Fix bad reference in UNIX comstack in function cs_addrstr.
670 Fix for compilation on AIX.
672 The generic front-end server (server/seshigh.c) now supports returning
673 Init diagnostics to the client in User-information-field, in
674 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
679 Allow any CQL relation (not just all,any,exact,scr).
681 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
682 that features the same UI.
684 Implemented command update0 in YAZ client which is equivalent to
685 update but uses old of Ext Update ASN.1.
687 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
688 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
689 Previously no OID was used for this info.
691 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
692 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
693 returns 'malformed search term' otherwise.
695 SortResponse member resultCount now set to NULL in sort handler of
698 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
701 Add three new utility functions for translating OIDs between various
702 formats -- symbolic name such as "Usmarc", minus-1-terminated int
703 arrays and dotted strings such as "1.2.840.10003.9.5.1":
704 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
705 char *oid_to_dotstring(const int *oid, char *oidbuf);
706 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
708 Reverted modifications for ES Update definition for z_IU0Update
709 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
710 is back to YAZ 2.0.2.
712 String value attributes for CCL parser.
714 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
715 which their FirstSearch server returns in Init responses, sometimes
716 carrying useful diagnostic information when Init fails. This has the
717 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
718 "z39.50/oclcui.asn", where its definition is somewhat different from
719 what OCLC document on their web-site, as required to interoperate with
722 Support for anonymous authentication in yaz-client. Use the command
725 * Fix the OID of the Index Data-local "admin" Extended Service from
726 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
727 the 1000, which indicates a locally-defined OID, was a mistake.
731 Fix CCL directive @case handling so that it affects string match for
732 both CCL keywords and qualifiers.
734 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
735 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
736 Decoder has been updated with ASN.1 changes as listed in
737 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
738 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
739 z_IUUpdate, remains unchanged.
741 ZOOM_record_get may now return a record in a specific character set.
742 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
743 "from" is the character set of record as returned by target. "to" is
744 the character set to be returned. If omitted, "to" is UTF-8.
746 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
748 New ODR utility, odr_getelement, which returns name of element for
749 which encoding/decoding failed.
751 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
752 in cases where a required element was omitted.
754 Bug fix: some MARC8 sequences were not converted.
756 New ZOOM option "step" which specifies number of records to be
757 retrieved in one chunk. Used in conjunction with "start" and "count".
759 SRW support for yaz-client. Use scheme http: to use it, e.g.
762 yaz-client no longer does (un)intelligent character set conversions
763 by default. Can be enabled with charset and marc_charset commands.
765 xmalloc trace fix for 64-bit systems such as DEC alpha.
767 Solaris 2.6 compile fix.
769 New function, cql_strerror() translates SRW error codes, as returned
770 by cql_transform_error(), into human-readable English strings. Used
771 in yaz-client diagnostics when appropriate.
773 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
774 converts it into a type-1 query which is sent to the server. This
775 makes CQL available for use with all Z-servers, as opposed to the tiny
776 minority that can handle CQL queries themselves.
780 New Debian package layout similar to the Redhat Package layout.
782 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
783 and search result respectively.
787 Redhat package is now several packages: libyaz (runtime libraries),
788 libyaz-devel (development and documentation, and yaz (utility programs).
789 Package spec file by Morten Bøgeskov.
791 New member 'schema' in struct bend_fetch_rr which the name of requested
792 schema (SRW/SRU) for record (or NULL if none was given). The fetch
793 handler MAY set this to reflect the schema of the returned record.
795 New member 'display_term' in struct scan_entry. GFS now sets member entries
796 and allocates scan entries to be filled by user scan handler. In previous
797 version, entries member was allocated by the scan handler. That still works,
798 but the GFS will ignore member display_term - assuming it was NOT set by
799 the handler. The fact that the GFS now allocates the entries both allows
800 for new members and makes a scan handler easier to write.
802 Fix CQL lex buffer overflow.
804 SRW/SRU recordPacking. For SRW default recordPacking is string. For
805 SRU default recordPacking is string.
807 SRU protocol support for frontend server.
809 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
811 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
813 Added scan for the ZOOM shell (zoomsh).
817 * String Identifers for Schemas (Amendment 5).
818 http://lcweb.loc.gov/z3950/agency/amend/am5.html
819 Old definition for schema
820 Odr_oid *schema; /* OPT */
825 Z_InternationalString *uri;
826 #define Z_Schema_oid 1
827 #define Z_Schema_uri 2
830 * resultCount parameter to Sort Response (Amendment 1).
831 http://lcweb.loc.gov/z3950/agency/amend/am1.html
833 Support for SRW 1.0 over HTTP. This is an optional feature and
834 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
837 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
838 on the same port. SRW SearchRetrieveRequests are mapped
839 to bend_init,bend_search,bend_fetch,bend_close.
841 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
843 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
844 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
846 ZOOM connections are SRW based if schem http is used for hostname
847 in connect, e.g. z = ZOOM_connection_new("http://myserver");
848 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
850 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
851 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
852 distance=n, order=true/false, relation=le, prox unit=word. If
853 n is omitted, distance 1 is used.
855 Fixed problem with C compiler include path in wrong order.
857 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
858 on Solaris. Patch from Ko van der Sloot.
860 New MARC decode API. All new functions operate on a yaz_marc_t
861 handle. The most important new functions are: yaz_marc_create,
862 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
863 decode and destroy respectively. Decoder can produce formats
864 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
865 include/yaz/marcdisp.h.
867 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
868 to UTF-8, UCS-32, wchar_t or Latin-1.
870 * Prototypes for yaz_iconv_-functions moved to separate header
871 include/yaz/yaz-iconv.h.
873 Make a few private functions 'static' in unix.c. This prevents
874 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
876 For ZOOM connection, the options targetImplementation{Id,Name,Version}
877 are set when Init Response is received.
879 New function ZOOM_connection_error_x similar to ZOOM_connection_error
880 but returns diagnostic set as well.
882 New function yaz_strerror which is a portable wrapper for
883 strerror/strerror_r/GetLastMessage.
885 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
886 is returned for MARC. If type is "oai", then OAI MARC is returned.
888 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
893 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
895 Fix bad race conditions on SIGTERM and terminate gracefully in
898 Move retrieval (data1) module to Zebra since nobody seems to be
901 Add GRS-1 render for ZOOM using same format as yaz-client.
905 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
907 Fix broken ESpec handling in data1 module.
909 SGML reader parses comments and makes them part of the data1 tree.
911 Added several type casts so that YAZ compiles as C++ code.
913 ZOOM didn't handle PDU encoding failures properly.
915 Added more Bib-1 diagnostics (approved extensions).
917 GNU configure: better check for iconv.
919 More portable use of accept, getpeername. Check for socklen_t. Use
920 int/size_t if socklen_t is not defined.
924 PQF parser rejects bad queries - including those with extra
925 characters in them. PQF parser used to silently ignore that.
926 Cleaner API for PQF added, which allows you to get detailed
927 error information for bad queries (see yaz/pquery.h).
929 Fixed bug in ZOOM_record_get for type "database".
931 Implemented mini iconv library supporting conversions between
932 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
934 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
938 Fixed ZOOM C record cache so that preferredRecordSyntax and
939 elementSetName is used to check for already fetched records.
943 Added three members in bend_initrequest structure to facilitate
944 character set negotiation.
946 Fixed a bug in frontend server that could cause indefinite
947 loops under rare conditions.
949 Revised character set utilities (charneg.h) so that encoding
950 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
952 For PQF, directive @term <type> sets term type for Scan/Search.
953 Here <type> is general, string, numeric, null. The term type
954 is inherited - just like @attr.
956 New call odr_set_charset that sets character set conversion for
957 international-strings on a ODR stream. Prototype is:
958 int odr_set_charset(ODR o, const char *to, const char *from);
959 The InternationalString is still represented as C string in YAZ
960 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
961 won't). On the protocol level, you can use any encoding.
963 Support for UNIX sockets in ZOOM.
965 Solaris recv sometimes returns errno == ENOENT. It is treated as
966 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
968 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
969 both client and server. Code by Morten Bøgeskov.
973 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
974 that they can be used directly from Visual Basic. You must recompile
975 your windows APP if you're using ZOOM.
977 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
978 Commands "lang" and "charset" sets language and character set respectively.
979 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
980 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
982 Attributes from multiple CCL fields may be OR'ed rather than merged
983 using directive "@field or". Fields are still merged by default -
984 equivalent to "@field merge".
986 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
989 Fixed bug in zget for parameter ExtendedServicesResponse.
995 Added PQF feature: '@attr type=value' may be written as '@type=value'.
997 Client displays USR.1:SearchResult-1 (hits per term).
999 Additional Search Info for search in Generic Frontend Server.
1001 Fixed CCL parsing of "field=s".
1003 WIN32 installer - using the excellent NSIS software from nullsoft.
1005 Fixed CCL parsing of "field = - <number>".
1007 Added function yaz_marc_decode that decodes MARC for line mode
1008 display or XML (similar to that used by JZKit).
1010 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1011 Z39.50. But ISO/ILL was, however.
1013 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1014 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

1017 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1019 --- 1.8.5 2002/02/03
1021 New YAZ client features: Command completion and new commands:
1022 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1023 Code provided by Jacob Poulsen.
1025 New call oid_trav, that visits all registered OIDs via callback.
1027 Function ZOOM_record_get now returns const char pointer rather than
1028 void pointer. It saves a lot of type casts.
1030 For YAZ client, command "auth" now allows you to set authentication
1031 in IdPass style. It is enabled when three tokens are given - order
1032 is user, group and password.
1034 Fix memory leaks in MARC record handling for ZOOM.
1036 New option for YAZ client, -k <kilobytes> that sets
1037 maximum record size. Similar to -k option for generic frontend
1038 server and yaz-ztest.
1040 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1042 Prefix query parser reports "fail" when bad attribute set is given.
1044 Fix in MARC decoder. Proximity logging. Fix for attribute set
1045 in scan handler for server. Patches by Shigeru Ishida.
1047 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1050 Configure option --with-openssl=<dir> now works when a directory is
1051 specified. Patch provided by Morten Bøgeskov.
1053 New option for YAZ client, -u <auth>, that sets authentication.
1055 ZOOM fix: error information was sometimes "missing", since error
1056 was cleared/reset too when it shouldn't.
1058 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1060 --- 1.8.4 2002/01/04
1062 Scan for ZOOM API. New object ZOOM_scanset. New functions
1063 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1064 ZOOM_scanset_destroy.
1066 New ZOOM function, ZOOM_connection_last_event, that returns type
1067 of last event (such as "receive data", "send data", "apdu received",
1070 New ZOOM option, schema, that specifies schema for retrieval.
1072 New CCL feature. Qualifiers can be aliases for one or more
1073 other qualifiers (if more than one is given, OR is used).
1075 ZOOM uses named result sets if target supports it.
1077 Two new YAZ client commands: . (dot, which sources a script of YAZ
1078 client commands), and ! (to execute shell command.). Implemented
1081 Working on Debian packages.
1083 --- 1.8.3 2001/11/19
1085 YAZ client enables named result sets only if target supports it.
1087 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1089 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1090 with key="host" to get same result.
1092 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1093 Function Z3950_resultset_record(s) returns references to records
1094 "owned" by resultset. To become owner use Z3950_record_clone.
1096 Function z_ext_record handles Extended Services. Thanks to
1099 --- 1.8.2 2001/11/12
1101 CCL Parser fix: ignore token comma when dealing with and-lists.
1103 Documentation updates for COMSTACK.
1105 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1106 Changed prototype Z3950_records. For some functions, int parameters
1107 were changed to size_t.
1109 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1112 New MARC decode/display function, marc_display_exl, which properly rejects
1113 non-ISO2709 records. YAZ client uses it.
1115 --- 1.8.1 2001/10/29
1117 Fix bug: local attribute set wasn't set correctly in PQF strings.
1121 * Old Z39.50 codecs no longer supported.
1123 Added ZOOM C binding. See http://zoom.z3950.org/
1125 Renamed states for COMSTACKs to avoid confusion with events.
1127 Implemented cs_look and proper cs_rcvconnect.
1129 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1131 Configure detects POSIX threads on OpenBSD.
1133 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1134 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1136 When error is returned from present handler, non-surrogate diagnostic
1137 is returned in present response (and fetch handler is no longer called).
1139 * Minor adjustments to pquery parser (PQF). Token characters may be
1140 escaped by using backslash (C-style).
1142 PQF parser allows string attribute values to be specified. For @attr,
1143 non-numeric characters after the equal-sign are treated as strings
1144 (e.g. @attr 9=title).
1146 CCL trunction character may be defined (@truncation in file)
1148 * function zget_ExtendedServicesRequest sets waitAction to
1149 waitIfPossible (was wait).
1151 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1154 CCL operator names may be set in field definition files (CCL_bibset).
1155 See ccl/bib1 for an example.
1157 Fixes in ASN.1 compiler for C++ compatibility.
1159 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1160 and "op_or" to avoid conflict with C++.
1162 Fixed problem with GNU readline detection on Redhat 7.0.
1164 Added step-size for Scan backend handler.
1166 Fixed bug that made the frontend server crash when no attribute
1167 set was specified for scan.
1169 Front-end server automatically switches to original working directory
1170 when installed as an NT service. Previously -w had to be specified to
1173 Added extended attributes for retrieval module (data1), so that data1
1174 records carry d1_readXML/SGML attributes. d1_read also supports
1175 null-data rules ( <tag/>)
1177 On UNIX when POSIX threads are available, a separate library libyazthread
1178 is created. Programmers should link with that library and the yaz library
1179 when using threads. The reason for the split was that some applications
1180 on Linux, such as Apache, doesn't work well when using shared objects that
1183 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1184 (or any frontend server) in SSL mode by specifying ssl: followed by
1185 address. Only tested on UNIX.
1187 Added feature for CCL module. Virtual structure s=al or s=ol generates
1188 and-list and or-list respectively instead of phrase search.
1192 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1193 log_mask_str. This was done to avoid name conflicts with other libraries
1194 (such as other PHP extensions).
1196 Added raw OID member for preferred record syntax (request_format_raw)
1197 and returned record syntax (output_format_raw) for backend fetch method.
1199 Config file yaz-config now accepts options so that it returns specific
1200 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1202 Shared library support for UNIX using GNU libtool.
1204 * Modified backend interface. Request/Response struct's replaced by
1205 one read/write C struct. For example bend_fetchrequest and
1206 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1207 Every handler - even search has to be registered in bend_init
1208 handler. This means that the YAZ library no longer refers to
1209 external functions and it makes it possible to make the whole
1210 thing a single DLL/SO.
1212 Added Segment handler for backend server.
1214 Added Zmbol/Zebra administrative functions to YAZ client.
1216 Threaded frontend server on UNIX (when POSIX Threads are available).
1217 Starting the server with option -T enables multi-threading.
1221 Added configure option --enable-comp/disable-comp to control use
1222 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1223 located in sub directory asn.
1225 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1226 in ${exec_prefix}/bin along with the other programs yaz-client and
1229 GNU automake used to maintain makefiles.
1231 Added several OID's.
1233 Changed retrieval module so that we can load records with no abstract
1234 syntax defined. Tagpaths in these records are fully composed of string
1237 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1241 On UNIX, the generated makefile now supports a proper 'make install'.
1242 The prefix can be set via GNU configure to set the install location
1243 (default is /usr/local).
1245 * YAZ programs client and ztest were renamed to yaz-client and
1246 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1247 locations, such as /usr/bin,/usr/local/bin,etc.
1249 * YAZ Header files were moved from include to include/yaz. YAZ Header
1250 files are referred to as include <yaz/log.h> rather than <log.h>.
1251 The YAZ include path (-I ..) is therefore the same as before. Programmers
1252 should update their #include statements or use -Ipath/include/yaz
1253 instead. The main motivation for doing this change is that YAZ header files
1254 can be installed in "standard" locations /usr/include,/usr/local/include
1255 without introducing conflicts, since ALL YAZ header files are stored
1256 in subdirectory yaz (under /usr/include for example).
1258 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1259 rather than project/workspace files. We switched because project files
1260 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1263 Changed name of logging function, logf, to yaz_log, to prevent name
1264 clash with some math-log functions. The YAZ header log.h defines logf
1265 to yaz_log (#define) so there should be no incompatibilities by this
1268 Added bend_start/bend_stop handlers for server. These handler are
1269 called on start/stop of server. For windows they are called whenever
1270 a service is started/stopped.
1272 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1273 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1274 in util/yc.tcl. The auto-generated C code structures are, in a few
1275 cases, incompatible with the old decoders. There are differences in the
1276 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1277 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1278 The preprocessor variable ASN_COMPILED is defined when the compiled
1279 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1280 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1281 wish to use the old encoders/decoders you can specify --disable-yc
1284 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1285 version so that it supports both new - and old version of DB Update
1287 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1288 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1289 change. The name parameter can be set to 0 in which no name is specified
1290 for the construction. The macros odr_implicit and odr_explicit sets name
1291 parameter to zero for the construction involved. New macros
1292 odr_implicit_tag and odr_explicit_tag are similar to the others,
1293 except that a name parameter is added. For programmers' that don't use
1294 ODR they probably only need to change the call to z_APDU and z_External.
1296 Added access control facility by interfacing the TCP wrapper library.
1297 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1298 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1299 name of the daemon and enables the access control as specified in
1300 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1302 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1303 den Dool <H.M.vdnDool@kub.nl>.
1305 Added reference ID parameter to most functions in server API - refer
1306 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1308 Changed name of ccl library to libccl.a (was ccl.a).
1310 Fixed bug in decoder for Explain (Category TargetInfo).
1312 Added support for GNU readline in client. Thanks to Jacob Poulsen
1313 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1315 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1316 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1317 IMPLEMENTATION! This change was made to the development version before
1318 the ZIG decided to retract the amendment. If any users MUST be
1319 compatible with the original Update definition, PLEASE CONTACT US, and
1320 we will include a separate definition corresponding to the old Update
1321 ES. Note that because of the change to the ASN.1 of the
1322 TaskPackageRecordStructure we cannot define a single structure that
1323 will support both versions.
1325 * Added const modifier to buffer parameter for some ODR/BER encoding
1326 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1327 completeWAIS, odr_dumpBER.
1329 Fixed bug in client.c which caused a crash when a scanResponse didn't
1330 contain positionOfTerm.
1332 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1333 * will cause an error in a client if a non-YAZ target sends both a
1334 * list of Scan entries and non-surrogate diagnostics.
1336 Retrieval module enhancements. Tag sets may be typed in the reference
1337 to it. From the .abs-file the "tagset" directive takes a third optional
1338 integer type for the tag set referenced. From a .tag-file the "include"
1339 directive takes a third optional type as well. The old "type" directive
1340 in the tag set itself is still recognized but acts as the default type
1343 Backend interface change. Individual Scan terms returned from bend_scan
1344 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1345 in include/backend.h.
1347 Retrieval module enhancements. Multiple tag sets and attribute sets may
1348 be specified in abstract syntax specs. Revised the error/warning for
1349 logging messages reported by the retrieval module when reading the
1352 Object Identifier system (oid_..) changed. The API is backwards
1353 compatible but the oid-routines now allocates new OID's when needed.
1354 Raw OID's may be specified in oid_getvalbyname.
1356 YAZ now uses GNU configure to generate Makefile(s).
1358 * Minor changes in some of the member names of DeleteResultSetRequest and
1359 DeleteResultSetResponse. See include/proto.h.
1361 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1362 and added member 'languages' in TargetInfo (which was missing).
1364 Changed the way attribute sets are handled in the retrieval
1365 module. These are now cached, just like the abstract syntaxes
1368 Changed YAZ so that it links with compiled ASN.1.
1370 Added Explain-schema definitions and mapping routines. The following
1371 Explain categories have been implemented: AttributeDetails,
1372 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1374 Fixed minor bug in Windows version of Server Library.
1376 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1378 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1380 Added EXTERNAL: UNIverse Resource Report (non-standard).
1382 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1383 ENUMERATED and SET OF.
1385 * Added 'const' to some of the char pointer arguments for the
1386 functions, data1_read_node, data1_getelementbytagname,
1387 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1390 Fixed bug in data1_insert_taggeddata - the last_child member of
1391 parent wasn't initialised.
1393 * Changed data1_read_record and data1_read_node so that the supplied
1394 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1395 doesn't refer to any parts of the "SGML"-buffer.
1397 Fixed bug in server library (Windows version of statserv_remove).
1399 * Changed code so that it compiles as C++. The type definition
1400 of Odr_fun which is a member of Odr_arm was changed. The result is,
1401 that an explicit typecast is needed for the fun pointer when
1402 using Odr_arm - as in:
1403 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1405 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1407 Implemented the new structured date and time definition as approved
1408 by the ZIG. Added schemaId element to the specificTag in Espec-1
1409 (also approved at the last ZIG). Thanks to RVDM.
1411 Added some Object identifiers (RVDM).
1413 Changed the Update Extended Service (RVDM).
1415 Added command "refid" to client which specifies referenceId for
1416 the following requests.
1418 Implemented extended service handling for server. See ztest.c
1419 for an example as well as backend.h. New handlers are registerd
1420 in the Init handler.
1422 * Changed interface for sort in server.
1424 Added new members to statserv_options_block. It allows a server
1425 to read options from another source than just the command line. Thanks
1426 to Charles Woodfield.
1428 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1429 renamed to zboolean. Some C++ compilers complained about the name.
1431 Minor changes to gils.abs. Added index 's' (sort) on title
1432 and date/time-last-modified.
1434 --- 1.4pl2 1998/1/30
1436 Fixed bug in server library regarding inetd mode (-i). This bug
1437 was introduced by release 1.4.
1439 --- 1.4pl1 1998/1/29
1441 Added sort facility in client and backend server interface.
1443 Fixed problem with dependencies in Makefile(s).
1445 Fixed bugs for encoders/decoders of extended services and
1448 Implemented sub-tree feature for schemas. Sub-trees are
1449 referenced in *.abs-files. See explain.abs for an example
1450 of the use of this feature.
1452 Modified bib1.att; local attributes for ANY didn't include
1453 ANY itself (only affects use of the retrieval module).
1455 Fixed bug in plain SGML reader in function data1_read_node:
1456 tags with prefix "var" was incorrectly interpreted as variants.
1458 Added feature "sub-schemas" to enable references to - and definitions
1459 of - group of elements.
1461 * Removed member parent from type data1_element (in data1.h).
1463 Implemented function odr_nullval() that returns the value of
1466 * Removed member num_children from data1_node (in data1.h).
1468 Made NT service interface part of the server library. The
1469 function statserv_main uses the NT service when required and
1470 calls the statserv_start / statserv_close routines.
1472 Routine zget_SearchRequest and zget_PresentRequest fills
1473 resultSetName/Id member with "default" instead of "Default".
1475 Fixed memory leak in server. Request queue member wasn't freed.
1477 Fixed nmem_exit so that memory is freed.
1481 Revised the CCL parser utility to be thread safe.
1483 Added function, oid_ent_to_oid, to replace the function
1484 oid_getoidbyent, which is not thread safe.
1486 * Added nmem_init and nmem_exit to initialize and release
1487 NMEM resources. Function nmem_init should be called once in the
1488 initial thread before NMEM/ODR is used. statserv.c and client.c
1489 have been changed accordingly. The change was necessary to make
1490 NMEM thread safe. The NMEM memory pool is shared amongst threads
1491 in a process. Unix-based applications will still work fine without
1494 Added NT Services interface for the the Z39.50 (statserv) Server.
1495 Refer to the ztest.c source on the usage.
1497 Windows 95/NT port using MSVC5.0. Project files are included in the
1500 * Defined new 'global' handle for the retrieval (data1) system. The
1501 new handled, data1_handle, describes the state of the data1 system.
1502 This handle is passed as first argument to virtually all
1503 data1 related routines. The functions data1_create and data1_destroy
1504 creates and destroys a data1 handle respectively.
1506 Added ODR encode stream member to all backend request structures
1507 init, search, scan etc. This stream should be used to allocate all
1508 memory used for the response when thread safe operation is needed.
1510 Changed the comstack utility, cs_addstr, to be thread safe. The
1511 returned hostname string returned by the function is now part the
1514 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1515 function. The cs_straddr takes a COMSTACK handle as argument, so this
1516 function must be used after cs_create and before bind/connect.
1517 This function is thread safe.
1519 Moved test server to 'ztest' directory - generic server code still
1520 in 'server' directory.
1522 Made prefix query (pquery.c) utility thread safe.
1524 Added new function modifier YAZ_EXPORT to 'export' public DLL
1525 functions when using windows (see include/yconfig.h).
1527 Added definitions to the OID database (util/oid.c) (RVDM).
1529 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1531 Added call to ccl_rpn_delete in client program.
1533 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1534 release of RPN structure.
1536 Added support for C++, headers uses extern "C" for public definitions.
1537 With input from RVDM.
1539 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1540 Thanks to Ronald van der Meer (RVDM).
1542 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1544 Added support for private extensions to the OID database
1545 (oid_setprivateoids()). Thanks to RVDM.
1547 Added optional, physical ANY (key replication)
1549 Fixed null-reference problem in GRS-1 output filter.
1551 Proximity operator added to Prefix Query Format (PQF).
1553 In test client command "base" accepts multiple databases.
1555 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1559 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1561 Smallish bug-fixes in the new encoders/decoders (explain).
1563 Bug fixed in DeleteRequest.
1565 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1567 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1569 Added SOIF syntax (using private OID for now) to retrieval module and client.
1571 Added Update extended service.
1573 Added SearchResult-1 additional info structure.
1575 Added optional CCL (ISO8777) interpreter as separate module. Available
1578 --- 1.2 1996/6/10 (1st anniversary release)
1580 Added Summary record syntax. Lightly tested.
1582 Added OPAC record syntax. Untested.
1584 Added ResourceReport service encoders/decoders. Untested.
1586 Fixed bug in z_Unit - wrong tagging on unitSystem.
1588 Fixed bug in the DiagRecs decoder.
1590 Added options for max PDU size and session timeout to frontend-server.
1592 Added documentation of query-language parsers and other supporting utilities.
1594 [frontend-server] Added Attribute set to the bend_scanrequest API.
1596 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1597 surrogate diagnostics were generated.
1599 [retrieval] Allow multiple local values for attribute.
1601 [retrieval] Allow multiple attributes per element in .abs files. index type.
1603 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1605 --- 1.1pl2 1996/4/10
1607 Minor changes, mostly specific to Zebra's requirements (retrieval)
1611 Repaired bug in frontend server when running multiple listening
1612 endpoints in dynamic mode.
1614 z_External() now won't break if a known, ASN.1 value comes encapsulated
1615 in an octet-string. The value will pass through unmodified in an Odr_oct.
1617 Added a bit of code to the demo client to decode & display
1618 ASN.1-structured records represented in the octet-aligned branch of
1619 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1621 Added z_ext_getentbyref() to the ASN module. Doc updated.
1623 * Completed the SCAN definition in the ASN module. This may break SCAN
1624 code based on older YAZ-versions at compile-time. The fix is easy -
1627 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1628 under the SCAN definition. Remember to initialize this, server-people.
1630 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1631 that this does not extend to ODR and ASN.
1633 Comstack allows insertion of established socket (primarily for
1634 inetd-operation of servers). Doc updated.
1636 Front-end server can now start from the inetd in TCP mode. Doc
1639 --- 1.0pl4 1996/1/24
1643 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1644 the rank and record number.
1646 Adjustments to the frontend server.
1648 Fixed diagnostic BER dumper. It ignored the file argument.
1652 Various changes to retrieval module.
1654 Changed the union discriminators of the protocol files from enums to
1655 ints paired with #defines.
1657 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1660 *Changed operator in the RPN structure to 'roperator', again to avoid a
1663 Fixed problems in Explain decoders/encoders.
1665 --- 1.0pl2 1995/12/6
1667 Memory bug in log module fixed.
1669 --- 1.0pl1 1995/12/5
1671 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1673 Bug in Explain DatabaseInfo module fixed.
1675 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1679 The shift to v1.0 signals that we now consider the *core* functionality
1680 of YAZ reasonably stable (the core being more or less equivalent to
1681 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1682 tested (Explain not at all - though that will happen soonish).
1684 Minor changes to code to support Windows port.
1686 Various minor changes after we're getting to use GRS-1 & co. more.
1688 Added Espec-1 format.
1690 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1691 of the protocol and it cannot be selected when encoding (maps into 'string'
1692 when decoding). Needed to talk to some servers.
1694 Demo client can request simple element set names.
1696 Added Diagnostic Format encoders/decoders.
1698 Added simple Close handling to frontend server (no hooks for resource
1699 reporting yet), and demonstration client.
1701 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1703 --- 1.0b3 1995/08/24
1705 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1706 handled incorrectly when records were requested in the searchResponse. This
1707 will only affect you if you use the frontend-server.
1709 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1710 Test-client will ask for and print GRS1. Ztest will return dummy records
1713 Added Explain encoders/decoders to the service-level API. Untested.
1715 Added Extended Services: Item Order encoders and decoders to the Service-
1716 level API. Untested. We could use a recent copy of the pertinent bits
1717 of the ILL protocol to add those bits.
1719 Added diagnostic format 1 encoders/decoders to the service-level API.
1722 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1723 odr_cons.c, which causes a more correct output.
1725 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1726 was always set to 0 when no records were requested in the searchRequest.
1728 * Added better external-handling. This shouldn't harm old code that
1729 *encodes* externals. It can break code that looks for a
1730 'single-ASN1-type' representation, since those types that are known
1731 are now decoded immediately. Look at the SUTRS sample code in
1732 seshigh.c and client.c. Documentation updated.
1734 Handling of structured records in bend_fetchresponse. Length -1 marks
1735 structured record, type is deduced from format field.
1737 --- 1.0b2 1995/06/27
1738 Fairly quick maintenance release to add SUTRS support.
1740 Fixed handling of SUTRS records in the demonstration client.
1742 * Added format field to the bend_fetchrequest and bend_fetchresponce
1743 structures of the backend API (frontend server). When the record is
1744 returned, the value of the format field is mapped to an OID. The
1745 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1746 of the record. The special value VAL_NONE in the bend_request means
1747 that no specific format was requested by the client. Documentation
1748 updated accordingly. Test server (ztest) will return a fixed dummy
1749 SUTRS record if your client requests SUTRS.
1751 Documentation updated accordingly.
1753 You can now set external libraries and RANLIB support in the top-level
1757 First public release.
