2 Translation of proximity nodes from CQL into PQF now works.
4 For SRW, accept application/soap+xml as content-type for SOAP msg.
8 Updated Windows package to include yazd.dll + yazd.lib for the
11 If the environment variable YAZ_LOG is set, then it is used as a
12 string indicating the default level of logging to use if not
13 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
14 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
15 used as before. So, for example, to omit warnings from YAZ logging,
18 cql_transform() now map structure and other attributes before indexes,
19 so that index-specific structures and other attributes can override
20 defaults. So now a combination of mapping specifications such as:
22 index.dc.date = 1=date-modified 4=5
25 cql_transform() now also respects the "always" mapping specification,
26 which establishes an initial set of attributes to be used for all
27 terms except where overridden by more specific attributes associated
28 with the index, relation or modifier.
30 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
31 which mode to use; one of "post", "get" or "soap" (SRW, default).
33 Fixes for yaz_iconv routines: changed trie-based character set conversions
34 to use only non-negative values for bit fields due to Sun's C compiler not
35 supporting negative values.
37 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
38 sequences where not read correctly. Fix by Rustam Usmanov.
40 Updated win/makefile to use options, settings which makes things
41 compile with VS C 2005.
45 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
47 In ZOOM socket code, use select instead of poll on MacOSX.
49 ZOOM-C now support client-side compilation of CQL into RPN that is
50 sent to the server, enabling CQL to be used against all Z39.50
51 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
52 ZOOM_query object, and submit it using ZOOM_connection_search().
53 The CQL-to-RPN translation uses a configuration file, the name of
54 which must be specified in the Connection's "cqlfile" option.
56 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
57 function, which takes as its start-term parameter a ZOOM_query object
58 (which may have had either CQL or RPN set into it).
63 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
64 GFS to support this as well. Backend handler, bend_srw_update, does the
65 update work. Code contributed by Ko van der Sloot.
67 Allow retrieval of Search Result-1 information in ZOOM by the use of
68 options that are attached to a result set. ZOOM documentation updated
71 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
72 UTF-8 conversion. Patch by Raj Patel.
74 Added option -m to GFS to control formatting of timestamps in log file.
76 Added 'exit' as synonym for 'quit' in yaz-client
78 Added support for specifying SRW resultSetId + resultSetIdleTime in a
79 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
80 for the new members. Patch by Ko van der Sloot.
82 Added support for SRU POST. It is supported for content-type
83 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
85 Do not build the separate Multi-threaded (MT) library libyazthread.la.
86 Instead make the library libyaz.la multi-threaded. Threading as a whole
87 can still be disabled by configure option --disable-threads. Previosly,
88 with older GLIBCs there were problems with MT libs under Apache. This
89 has now been fixed a long time ago.
91 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
94 CQL module modified to be case insensitive for relations/indexes/operations.
96 Fixed bug in CQL transform code: incorrect value relationModifieder
99 Added 'show all' command for yaz-client which retrieves all results
102 Added new yaz-client, xmles, which takes a (private) OID and
103 a document to be sent as an extended service request.
105 Describe new yaz-client commands wait_response and set_auto_wait.
107 Increase TCP/IP listener backlog from 3 (which I am guessing was
108 copied from the SunOS manual entry way back when) so SOMAXCONN, so
109 that the socket will queue as many incoming connections as it's able
110 to handle ongoing connections. In other words, it will never now
111 refuse a connection that it would be able to handle merely because
112 it's not got around to accepting() enough of the pending connections
113 yet. This is the behaviour anyway under Linux, where the listen()
114 argument is ignored; but not under BSD and on systems such as
115 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
116 YAZ-based servers should now be uniform across operating systems in
119 yaz-marcdump uses 64-bit file access on some systems. This is enabled
120 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
121 This allows yaz-marcdump to read large MARC batches (>2 GB).
123 Modified all YAZ source files - except the source which is auto-generated
124 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
127 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
128 corresponding to the existing *_setl() function. These allow option
129 values containing arbitrary valuues.
131 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
132 ZOOM_resultset_sort() in new applications. Its behaviour is identical
133 except that it returns an indicator of whether or not the sort
134 criterion was accepted (0 for OK, -1 for invalid).
138 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
139 MARC output rather than returning "new" buffer.
141 yaz-client warns about unknown init options.
143 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
147 Added support for SRW sort in Generic Frontend Server. Patch
148 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
149 sortKeys - or NULL if none is provided.
151 Fixed bug #307: It was impossible to specify indefinite/no timeout
152 for ZOOM_event. Special timeout value -1 now means indefinite timeout
155 Added support for multiple languages and charsets to be specified in
156 ZOOM. Each charset/language is separated by a blank. If negotiation is
157 in effect in init-response, Option
158 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
159 Code based on patch by Vasiliy Osadchuk.
161 Fixed bug #306: infinite recursion that occurred when calling
162 yaz_log_level_init as the first call (before other log level or
165 Fixed bug in scan handling in front end server: if preferred-Position-In-
166 Response was non-present, a NULL pointer referece was performed.
170 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
171 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
172 now defined for all those error codes. So instead of putting 109 in
173 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
174 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
176 Modified the yaz-marcdump utility to skip garbage bytes between MARC
179 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
181 Program yaz-client now exits and produces an error message if multiple
182 Z39.50 servers are specified on the command line (none or one allowed
185 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
190 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
192 Fixed bug #272: Preserve spacing for CCL terms.
196 Added support for virtual hosts and multiple backend servers for
197 the YAZ frontend server. The configution is XML based and
198 support specificition of CQL to RPN mappings and explain information.
199 See section "Virtual Hosts" in the YAZ manual.
201 Extended OPAC display utility. OPAC display utility renders
202 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
203 to supplement yaz_marc_decode_wrbuf.
205 Fixed a bug in MARC decoder that could caused it to crash for some
206 invalid MARC records. More diagnostics and warnings where added in
207 XML output (warnings, etc are stored in comments).
209 --- 2.0.34 2005/02/08
211 Fixes for UNIX domain sockets. Bug #261.
213 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
215 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
216 Added yaz_marc_subfield_str which defines subfield lead string which is
217 used in YAZ_MARC_LINE format. Default string is blank+$. Added
218 yaz_marc_endline_str which defines end of fields string used in
219 YAZ_MARC_LINE format. Default string is newline.
221 Experimental support for MarcXChange. This format can be produced
222 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
223 http://www.bs.dk/standards/MarcXchange.xsd
225 Added yaz-client commands scansize that sets maximum number of
226 entries to be returned by scan.
228 --- 2.0.32 2005/01/11
230 Added support for SRW scan in yaz-client and Generic Frontend Server.
232 * Added whereInList member to SRW Scan Term.
234 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
236 Fixed NMEM system to return aligned blocks on the smallest boundaries
237 that are suitably aligned for all possible types on the particular
238 architecture YAZ is being built for.
240 --- 2.0.30 2005/01/04
242 Fixed numerious warnings that was issued with newer versions of GCC.
244 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
245 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
248 Make YAZ Generic Frontend Server slightly faster.
250 Enhance (and reduce) logging for Generic Frontend Server.
252 Revert YAZ log system so that it flushes every write operation
253 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
255 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
256 instead of LOG_, due to name clash with syslog(3). LOG_ are still
257 present. New applications should define YAZ_USE_NEW_LOG=1 - this
258 will effectively disable old definitions.
260 --- 2.0.28 2004/11/09
262 Added yaz_log_time_format which specifies log format using
265 Added yaz_log_module_level which returns mask for a module. Value
266 is non-zero mask a if module is enabled; zero if disabled.
268 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
269 in include/yaz/cql.h.
271 Fixed bug #176: Dont throw diagnostics on empty SRU args.
273 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
275 Fixed bug #172: RPM builds does not enable SSL.
277 Doxyfile.in part of dist. Doxyfile generated by configure.
279 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
280 are given and the corresponding component does not exist.
282 Extend CCL documentation in YAZ reference. Describe r=r.
284 --- 2.0.26 2004/10/01
286 Fixed MARC->MARCXML conversion to properly deal with
287 fields, subfields, indicators having non-ASCII characters.
289 Fixed MARC->MARCXML conversion so that ASCII control characters
290 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
293 Added YAZ GFS support for conversion from Z39.50 surrogate
294 diagnostics to SRW surrogate diagnostics.
296 Bug fix: YAZ GFS did not return schema in explainResponse.
298 --- 2.0.25 2004/09/30
300 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
301 now converts recordSchema to elementSetName as well as schema URI.
303 Fixed bug in COMSTACK that prevented HTTP request packages from being
306 --- 2.0.24 2004/09/29
308 Added CCL facility r=r "range" which is similar to r=o "ordered" but
309 does not require white-space before and after the dash in a range, e.g.
310 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
313 Fixed a few AC_TRY_LINK configure tests that did not operate properly
314 due to new GCC removing "redundant" code.
316 Added yaz-client commands scanpos and scanstep that sets preferred
317 position and step-size for scan.
319 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
321 Added CCL utility ccl_qual_buf which parses one or more CCL
322 spec lines in a buffer.
324 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
325 of name and value - ignoring empty lines and comments.
327 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
329 Added odr_get_element_path which returns current element path for an
330 ODR handle. This utility is useful in error handling or user-defined
333 Added ODR_PRINT utility odr_set_stream which is is a more generic
334 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
335 to a write function and pointer to close function. The close function - if
336 non-NULL - will be called during odr_destroy.
338 Fixed bug in CCL parser where truncation char was not removed from
339 right side when truncation=both was in effect.
341 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
344 --- 2.0.23 2004/08/11
346 Fix buffer overrun in CQL parser when dealing with proximity (%).
348 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
349 to UTF-8/UCS conversion is now only based on codetables.xml.
351 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
353 --- 2.0.22 2004/08/06
355 Add support for more "commit changes" in ZOOM (uses Extended Services).
357 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
360 Yet another small fix for configure of SSL.
362 --- 2.0.21 2004/05/14
364 Fix SSL libs for configure when --with-openssl=DIR is given.
366 --- 2.0.20 2004/05/10
368 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
370 SSL comstack now uses yaz.pem certificate file on server side
371 by default. Certificate filename can be configured by calling
372 comstack function cs_set_ssl_certificate_file before cs_bind is used.
374 Fix bug regarding multiple calls to ZOOM_connection_connect.
376 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
378 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
379 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
381 ZOOM now allows inspection of X509 peer certificate for verification.
382 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
384 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
385 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
386 as "modular" but it simplifies things.
388 Added cs_get_peer_certificate to that returns peer X509 PEM.
390 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
391 NULL if SSL is unavailable.
393 Documentation about MARC decoding tools.
395 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
397 --- 2.0.19 2004/03/30
399 Rename CHANGELOG to NEWS to follow GNU style packing.
401 Fix bug with missing initialization of member in init_diagnostics.
402 This bug affects threaded version of GFS server.
404 --- 2.0.18 2004/03/20
406 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
409 Ensure zlib.dll is packed with Windows install.
411 --- 2.0.17 2004/03/17
413 Fix encoding of xsd:string to use text instead of CDATA.
415 Fix endless loop in CQL parser with unbalanced ".
417 Use a more compact way to store MARC-8 conversion tables.
419 --- 2.0.16 2004/03/16 Debian only
421 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
424 Update CQL parser to use new CQL 1.1 modifiers for booleans and
429 --- 2.0.15 2004/03/01
431 Another fix for decoding of XML packed records.
433 --- 2.0.14 2004/02/25
435 Fixes for Chunked encoding. White space not ignored after length spec.
437 Update NS and use default NS for SRW diagnostic elements.
439 --- 2.0.13 2004/02/23
441 Implement ZOOM_resultset_cache_reset which resets record cache.
443 Implement ZOOM_resultset_sort which sorts a result set.
445 Implement chunked HTTP transfer.
447 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
449 --- 2.0.12 2004/02/16
451 Added member 'schema' to bend_explain_rr structure so that backend
452 can specify explain record identifier. Defaults to Zeerex 2.0.
454 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
456 --- 2.0.11 2004/02/16
458 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
461 Added init command for yaz-client which sends "extra" init request.
463 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
464 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
466 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
468 Make ZOOM error code for "invalid query".
470 Fixed compilation for SSL which wasn't properly enabled for all platforms.
472 --- 2.0.10 2004/02/05
474 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
477 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
479 Added option -p <file> to make Generic Frontend Server to write PID file.
481 Added option -D to put Generic Frontend Server in background on its own.
483 Make ZOOM C recognize option "password". If unset, "pass" is used
484 (for backwards compatibility).
486 Fixed a bug in Generic Frontend Server that could make it crash if a
487 client sets characterSetNegotation bit, but didn't pass negotiation stuff
490 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
491 Must be issued before open, in order to be in effect.
493 --- 2.0.9-6 2004/01/12 Debian/Windows
495 Make the SRU server more picky WRT unknown params, etc.
497 Bug fix: ZOOM scan response didn't return displayTerm - when present.
499 New YAZ client command, options, that sets Z39.50 options.
501 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
502 options from a string of tokens (one token for each option bit).
504 Update SRW diagnostic code messages.
506 --- 2.0.9-5 2004/01/07 Debian/Windows
508 Handle user defined stylesheet for SRW/SRU.
510 --- 2.0.9-4 2004/01/06 Debian/Windows
512 Fix bug in decoding of Content-Length.
514 --- 2.0.9-3 2004/01/06 Debian/Windows
516 Fix a bug with decoding of XML packed records.
518 --- 2.0.9-2 2004/01/05 Debian only
520 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
522 Fix bug in SRW/SRU diagnostics decoding.
526 Fixed bug in Generic Frontend Server which could drop records exceeding
527 preferred message size. Reported and fixed by Irina Dijour.
529 Fixed calculation of package size for structured records in Generic
530 Frontend Server. Reported and fixed by Irina Dijour.
532 Fixed namespace for SRW/SRU diagnostics.
534 Fixed SEGV in yaz-client that occured for HTTP connection errors.
538 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
539 this version is incompatible with version 1.0 and older YAZ SRW/SRU
542 CQL changes to reflect recent changes to the specification:
543 * Documentation talks about context sets instead of index sets.
544 * Documentation talks about indexes instead of qualifiers.
545 * The CQL-to-PQF transformer's configuration file now uses
546 "index.set.name = <attributes>" instead of the old form
547 "qualifier.set.name = <attributes>". (Both forms are still
548 understood but the latter is deprecated.)
549 * CQL terms with no explicit index specified are now interpreted as
550 cql.serverChoice instead of srw.serverChoice (which of course
551 behaves exactly the same.)
555 MARC conversion can now generate ISO2709 output in another
556 character set. yaz-marcdump uses this facility if you invoke it
559 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
560 functions from there can be used from C++.
564 Frontend server now transfers memory from decoded packages to stream
567 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
568 references to show up.
570 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
571 the ZOOM Abstract API. The older names for the same options are still
572 also supported for the benefit of old applications.
574 ZOOM-C supports "implementationId" and "implementationVersion" options
575 to go along with "implementationName". These allow the user code to
576 specify identification strings to be sent to servers.
577 Add OID for the new ExtLite attribute set.
579 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
580 as requested/supplid by Ere Maijala <ere@atp.fi>
582 For generic frontend server, reverse the order of
583 "toolkit-supplied / application-supplied" strings sent as implementationId,
584 Name and Version. Also, remove the spaces around the slash. This brings
585 the GFS in line with the behaviour of ZOOM-C on the client side.
587 Add function ZOOM_scanset_display_term.
589 yaz-client shows scan displayTerm if present.
591 Utility yaz-iconv is now installed by default along with the man page
594 Extend configure check for OpenSSL to use pkg-config where available (such
597 Incorporate patch by Morten Bogeskov which allows a Unix file socket
598 server to specify uid/gid/mask for socket using the format
599 unix:[user=uid,][group=gid,][umask=mask,]file=path
600 If file= is omitted the existing format is assumed, e.g.
602 in which case the mask is 0666 (rw for everybody).
604 Major restructure of YAZ source. All source in libyaz is in src directory.
605 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
606 util (utility programs such as ASN.1 compiler, yaz-marcdump).
608 Added man page for utility yaz-marcdump (used to be called marcdump).
609 yaz-marcdump is installed by 'make install'.
611 Fixed a memory leak in Generic Frontend Server that occurred when decoding
612 of incoming package failed.
614 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
616 Change prototype of odr_perror: add const to message string.
618 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
620 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
621 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
622 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
623 DNS lookup. There should not be any compatibility problems with this
624 assuming that blocking=1 or 0 is used.
626 Fix bad reference in UNIX comstack in function cs_addrstr.
628 Fix for compilation on AIX.
630 The generic front-end server (server/seshigh.c) now supports returning
631 Init diagnostics to the client in User-information-field, in
632 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
637 Allow any CQL relation (not just all,any,exact,scr).
639 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
640 that features the same UI.
642 Implemented command update0 in YAZ client which is equivalent to
643 update but uses old of Ext Update ASN.1.
645 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
646 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
647 Previously no OID was used for this info.
649 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
650 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
651 returns 'malformed search term' otherwise.
653 SortResponse member resultCount now set to NULL in sort handler of
656 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
659 Add three new utility functions for translating OIDs between various
660 formats -- symbolic name such as "Usmarc", minus-1-terminated int
661 arrays and dotted strings such as "1.2.840.10003.9.5.1":
662 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
663 char *oid_to_dotstring(const int *oid, char *oidbuf);
664 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
666 Reverted modifications for ES Update definition for z_IU0Update
667 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
668 is back to YAZ 2.0.2.
670 String value attributes for CCL parser.
672 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
673 which their FirstSearch server returns in Init responses, sometimes
674 carrying useful diagnostic information when Init fails. This has the
675 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
676 "z39.50/oclcui.asn", where its definition is somewhat different from
677 what OCLC document on their web-site, as required to interoperate with
680 Support for anonymous authentication in yaz-client. Use the command
683 * Fix the OID of the Index Data-local "admin" Extended Service from
684 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
685 the 1000, which indicates a locally-defined OID, was a mistake.
689 Fix CCL directive @case handling so that it affects string match for
690 both CCL keywords and qualifiers.
692 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
693 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
694 Decoder has been updated with ASN.1 changes as listed in
695 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
696 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
697 z_IUUpdate, remains unchanged.
699 ZOOM_record_get may now return a record in a specific character set.
700 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
701 "from" is the character set of record as returned by target. "to" is
702 the character set to be returned. If omitted, "to" is UTF-8.
704 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
706 New ODR utility, odr_getelement, which returns name of element for
707 which encoding/decoding failed.
709 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
710 in cases where a required element was omitted.
712 Bug fix: some MARC8 sequences were not converted.
714 New ZOOM option "step" which specifies number of records to be
715 retrieved in one chunk. Used in conjunction with "start" and "count".
717 SRW support for yaz-client. Use scheme http: to use it, e.g.
720 yaz-client no longer does (un)intelligent character set conversions
721 by default. Can be enabled with charset and marc_charset commands.
723 xmalloc trace fix for 64-bit systems such as DEC alpha.
725 Solaris 2.6 compile fix.
727 New function, cql_strerror() translates SRW error codes, as returned
728 by cql_transform_error(), into human-readable English strings. Used
729 in yaz-client diagnostics when appropriate.
731 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
732 converts it into a type-1 query which is sent to the server. This
733 makes CQL available for use with all Z-servers, as opposed to the tiny
734 minority that can handle CQL queries themselves.
738 New Debian package layout similar to the Redhat Package layout.
740 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
741 and search result respectively.
745 Redhat package is now several packages: libyaz (runtime libraries),
746 libyaz-devel (development and documentation, and yaz (utility programs).
747 Package spec file by Morten Bøgeskov.
749 New member 'schema' in struct bend_fetch_rr which the name of requested
750 schema (SRW/SRU) for record (or NULL if none was given). The fetch
751 handler MAY set this to reflect the schema of the returned record.
753 New member 'display_term' in struct scan_entry. GFS now sets member entries
754 and allocates scan entries to be filled by user scan handler. In previous
755 version, entries member was allocated by the scan handler. That still works,
756 but the GFS will ignore member display_term - assuming it was NOT set by
757 the handler. The fact that the GFS now allocates the entries both allows
758 for new members and makes a scan handler easier to write.
760 Fix CQL lex buffer overflow.
762 SRW/SRU recordPacking. For SRW default recordPacking is string. For
763 SRU default recordPacking is string.
765 SRU protocol support for frontend server.
767 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
769 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
771 Added scan for the ZOOM shell (zoomsh).
775 * String Identifers for Schemas (Amendment 5).
776 http://lcweb.loc.gov/z3950/agency/amend/am5.html
777 Old definition for schema
778 Odr_oid *schema; /* OPT */
783 Z_InternationalString *uri;
784 #define Z_Schema_oid 1
785 #define Z_Schema_uri 2
788 * resultCount parameter to Sort Response (Amendment 1).
789 http://lcweb.loc.gov/z3950/agency/amend/am1.html
791 Support for SRW 1.0 over HTTP. This is an optional feature and
792 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
795 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
796 on the same port. SRW SearchRetrieveRequests are mapped
797 to bend_init,bend_search,bend_fetch,bend_close.
799 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
801 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
802 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
804 ZOOM connections are SRW based if schem http is used for hostname
805 in connect, e.g. z = ZOOM_connection_new("http://myserver");
806 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
808 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
809 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
810 distance=n, order=true/false, relation=le, prox unit=word. If
811 n is omitted, distance 1 is used.
813 Fixed problem with C compiler include path in wrong order.
815 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
816 on Solaris. Patch from Ko van der Sloot.
818 New MARC decode API. All new functions operate on a yaz_marc_t
819 handle. The most important new functions are: yaz_marc_create,
820 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
821 decode and destroy respectively. Decoder can produce formats
822 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
823 include/yaz/marcdisp.h.
825 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
826 to UTF-8, UCS-32, wchar_t or Latin-1.
828 * Prototypes for yaz_iconv_-functions moved to separate header
829 include/yaz/yaz-iconv.h.
831 Make a few private functions 'static' in unix.c. This prevents
832 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
834 For ZOOM connection, the options targetImplementation{Id,Name,Version}
835 are set when Init Response is received.
837 New function ZOOM_connection_error_x similar to ZOOM_connection_error
838 but returns diagnostic set as well.
840 New function yaz_strerror which is a portable wrapper for
841 strerror/strerror_r/GetLastMessage.
843 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
844 is returned for MARC. If type is "oai", then OAI MARC is returned.
846 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
851 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
853 Fix bad race conditions on SIGTERM and terminate gracefully in
856 Move retrieval (data1) module to Zebra since nobody seems to be
859 Add GRS-1 render for ZOOM using same format as yaz-client.
863 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
865 Fix broken ESpec handling in data1 module.
867 SGML reader parses comments and makes them part of the data1 tree.
869 Added several type casts so that YAZ compiles as C++ code.
871 ZOOM didn't handle PDU encoding failures properly.
873 Added more Bib-1 diagnostics (approved extensions).
875 GNU configure: better check for iconv.
877 More portable use of accept, getpeername. Check for socklen_t. Use
878 int/size_t if socklen_t is not defined.
882 PQF parser rejects bad queries - including those with extra
883 characters in them. PQF parser used to silently ignore that.
884 Cleaner API for PQF added, which allows you to get detailed
885 error information for bad queries (see yaz/pquery.h).
887 Fixed bug in ZOOM_record_get for type "database".
889 Implemented mini iconv library supporting conversions between
890 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
892 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
896 Fixed ZOOM C record cache so that preferredRecordSyntax and
897 elementSetName is used to check for already fetched records.
901 Added three members in bend_initrequest structure to facilitate
902 character set negotiation.
904 Fixed a bug in frontend server that could cause indefinite
905 loops under rare conditions.
907 Revised character set utilities (charneg.h) so that encoding
908 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
910 For PQF, directive @term <type> sets term type for Scan/Search.
911 Here <type> is general, string, numeric, null. The term type
912 is inherited - just like @attr.
914 New call odr_set_charset that sets character set conversion for
915 international-strings on a ODR stream. Prototype is:
916 int odr_set_charset(ODR o, const char *to, const char *from);
917 The InternationalString is still represented as C string in YAZ
918 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
919 won't). On the protocol level, you can use any encoding.
921 Support for UNIX sockets in ZOOM.
923 Solaris recv sometimes returns errno == ENOENT. It is treated as
924 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
926 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
927 both client and server. Code by Morten Bøgeskov.
931 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
932 that they can be used directly from Visual Basic. You must recompile
933 your windows APP if you're using ZOOM.
935 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
936 Commands "lang" and "charset" sets language and character set respectively.
937 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
938 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
940 Attributes from multiple CCL fields may be OR'ed rather than merged
941 using directive "@field or". Fields are still merged by default -
942 equivalent to "@field merge".
944 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
947 Fixed bug in zget for parameter ExtendedServicesResponse.
953 Added PQF feature: '@attr type=value' may be written as '@type=value'.
955 Client displays USR.1:SearchResult-1 (hits per term).
957 Additional Search Info for search in Generic Frontend Server.
959 Fixed CCL parsing of "field=s".
961 WIN32 installer - using the excellent NSIS software from nullsoft.
963 Fixed CCL parsing of "field = - <number>".
965 Added function yaz_marc_decode that decodes MARC for line mode
966 display or XML (similar to that used by JZKit).
968 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
969 Z39.50. But ISO/ILL was, however.
971 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
972 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
974 http://lcweb.loc.gov/z3950/agency/amend/am2.html
975 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
979 New YAZ client features: Command completion and new commands:
980 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
981 Code provided by Jacob Poulsen.
983 New call oid_trav, that visits all registered OIDs via callback.
985 Function ZOOM_record_get now returns const char pointer rather than
986 void pointer. It saves a lot of type casts.
988 For YAZ client, command "auth" now allows you to set authentication
989 in IdPass style. It is enabled when three tokens are given - order
990 is user, group and password.
992 Fix memory leaks in MARC record handling for ZOOM.
994 New option for YAZ client, -k <kilobytes> that sets
995 maximum record size. Similar to -k option for generic frontend
996 server and yaz-ztest.
998 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1000 Prefix query parser reports "fail" when bad attribute set is given.
1002 Fix in MARC decoder. Proximity logging. Fix for attribute set
1003 in scan handler for server. Patches by Shigeru Ishida.
1005 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1008 Configure option --with-openssl=<dir> now works when a directory is
1009 specified. Patch provided by Morten Bøgeskov.
1011 New option for YAZ client, -u <auth>, that sets authentication.
1013 ZOOM fix: error information was sometimes "missing", since error
1014 was cleared/reset too when it shouldn't.
1016 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1018 --- 1.8.4 2002/01/04
1020 Scan for ZOOM API. New object ZOOM_scanset. New functions
1021 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1022 ZOOM_scanset_destroy.
1024 New ZOOM function, ZOOM_connection_last_event, that returns type
1025 of last event (such as "receive data", "send data", "apdu received",
1028 New ZOOM option, schema, that specifies schema for retrieval.
1030 New CCL feature. Qualifiers can be aliases for one or more
1031 other qualifiers (if more than one is given, OR is used).
1033 ZOOM uses named result sets if target supports it.
1035 Two new YAZ client commands: . (dot, which sources a script of YAZ
1036 client commands), and ! (to execute shell command.). Implemented
1039 Working on Debian packages.
1041 --- 1.8.3 2001/11/19
1043 YAZ client enables named result sets only if target supports it.
1045 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1047 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1048 with key="host" to get same result.
1050 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1051 Function Z3950_resultset_record(s) returns references to records
1052 "owned" by resultset. To become owner use Z3950_record_clone.
1054 Function z_ext_record handles Extended Services. Thanks to
1057 --- 1.8.2 2001/11/12
1059 CCL Parser fix: ignore token comma when dealing with and-lists.
1061 Documentation updates for COMSTACK.
1063 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1064 Changed prototype Z3950_records. For some functions, int parameters
1065 were changed to size_t.
1067 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1070 New MARC decode/display function, marc_display_exl, which properly rejects
1071 non-ISO2709 records. YAZ client uses it.
1073 --- 1.8.1 2001/10/29
1075 Fix bug: local attribute set wasn't set correctly in PQF strings.
1079 * Old Z39.50 codecs no longer supported.
1081 Added ZOOM C binding. See http://zoom.z3950.org/
1083 Renamed states for COMSTACKs to avoid confusion with events.
1085 Implemented cs_look and proper cs_rcvconnect.
1087 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1089 Configure detects POSIX threads on OpenBSD.
1091 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1092 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1094 When error is returned from present handler, non-surrogate diagnostic
1095 is returned in present response (and fetch handler is no longer called).
1097 * Minor adjustments to pquery parser (PQF). Token characters may be
1098 escaped by using backslash (C-style).
1100 PQF parser allows string attribute values to be specified. For @attr,
1101 non-numeric characters after the equal-sign are treated as strings
1102 (e.g. @attr 9=title).
1104 CCL trunction character may be defined (@truncation in file)
1106 * function zget_ExtendedServicesRequest sets waitAction to
1107 waitIfPossible (was wait).
1109 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1112 CCL operator names may be set in field definition files (CCL_bibset).
1113 See ccl/bib1 for an example.
1115 Fixes in ASN.1 compiler for C++ compatibility.
1117 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1118 and "op_or" to avoid conflict with C++.
1120 Fixed problem with GNU readline detection on Redhat 7.0.
1122 Added step-size for Scan backend handler.
1124 Fixed bug that made the frontend server crash when no attribute
1125 set was specified for scan.
1127 Front-end server automatically switches to original working directory
1128 when installed as an NT service. Previously -w had to be specified to
1131 Added extended attributes for retrieval module (data1), so that data1
1132 records carry d1_readXML/SGML attributes. d1_read also supports
1133 null-data rules ( <tag/>)
1135 On UNIX when POSIX threads are available, a separate library libyazthread
1136 is created. Programmers should link with that library and the yaz library
1137 when using threads. The reason for the split was that some applications
1138 on Linux, such as Apache, doesn't work well when using shared objects that
1141 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1142 (or any frontend server) in SSL mode by specifying ssl: followed by
1143 address. Only tested on UNIX.
1145 Added feature for CCL module. Virtual structure s=al or s=ol generates
1146 and-list and or-list respectively instead of phrase search.
1150 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1151 log_mask_str. This was done to avoid name conflicts with other libraries
1152 (such as other PHP extensions).
1154 Added raw OID member for preferred record syntax (request_format_raw)
1155 and returned record syntax (output_format_raw) for backend fetch method.
1157 Config file yaz-config now accepts options so that it returns specific
1158 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1160 Shared library support for UNIX using GNU libtool.
1162 * Modified backend interface. Request/Response struct's replaced by
1163 one read/write C struct. For example bend_fetchrequest and
1164 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1165 Every handler - even search has to be registered in bend_init
1166 handler. This means that the YAZ library no longer refers to
1167 external functions and it makes it possible to make the whole
1168 thing a single DLL/SO.
1170 Added Segment handler for backend server.
1172 Added Zmbol/Zebra administrative functions to YAZ client.
1174 Threaded frontend server on UNIX (when POSIX Threads are available).
1175 Starting the server with option -T enables multi-threading.
1179 Added configure option --enable-comp/disable-comp to control use
1180 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1181 located in sub directory asn.
1183 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1184 in ${exec_prefix}/bin along with the other programs yaz-client and
1187 GNU automake used to maintain makefiles.
1189 Added several OID's.
1191 Changed retrieval module so that we can load records with no abstract
1192 syntax defined. Tagpaths in these records are fully composed of string
1195 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1199 On UNIX, the generated makefile now supports a proper 'make install'.
1200 The prefix can be set via GNU configure to set the install location
1201 (default is /usr/local).
1203 * YAZ programs client and ztest were renamed to yaz-client and
1204 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1205 locations, such as /usr/bin,/usr/local/bin,etc.
1207 * YAZ Header files were moved from include to include/yaz. YAZ Header
1208 files are referred to as include <yaz/log.h> rather than <log.h>.
1209 The YAZ include path (-I ..) is therefore the same as before. Programmers
1210 should update their #include statements or use -Ipath/include/yaz
1211 instead. The main motivation for doing this change is that YAZ header files
1212 can be installed in "standard" locations /usr/include,/usr/local/include
1213 without introducing conflicts, since ALL YAZ header files are stored
1214 in subdirectory yaz (under /usr/include for example).
1216 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1217 rather than project/workspace files. We switched because project files
1218 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1221 Changed name of logging function, logf, to yaz_log, to prevent name
1222 clash with some math-log functions. The YAZ header log.h defines logf
1223 to yaz_log (#define) so there should be no incompatibilities by this
1226 Added bend_start/bend_stop handlers for server. These handler are
1227 called on start/stop of server. For windows they are called whenever
1228 a service is started/stopped.
1230 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1231 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1232 in util/yc.tcl. The auto-generated C code structures are, in a few
1233 cases, incompatible with the old decoders. There are differences in the
1234 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1235 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1236 The preprocessor variable ASN_COMPILED is defined when the compiled
1237 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1238 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1239 wish to use the old encoders/decoders you can specify --disable-yc
1242 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1243 version so that it supports both new - and old version of DB Update
1245 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1246 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1247 change. The name parameter can be set to 0 in which no name is specified
1248 for the construction. The macros odr_implicit and odr_explicit sets name
1249 parameter to zero for the construction involved. New macros
1250 odr_implicit_tag and odr_explicit_tag are similar to the others,
1251 except that a name parameter is added. For programmers' that don't use
1252 ODR they probably only need to change the call to z_APDU and z_External.
1254 Added access control facility by interfacing the TCP wrapper library.
1255 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1256 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1257 name of the daemon and enables the access control as specified in
1258 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1260 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1261 den Dool <H.M.vdnDool@kub.nl>.
1263 Added reference ID parameter to most functions in server API - refer
1264 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1266 Changed name of ccl library to libccl.a (was ccl.a).
1268 Fixed bug in decoder for Explain (Category TargetInfo).
1270 Added support for GNU readline in client. Thanks to Jacob Poulsen
1271 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1273 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1274 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1275 IMPLEMENTATION! This change was made to the development version before
1276 the ZIG decided to retract the amendment. If any users MUST be
1277 compatible with the original Update definition, PLEASE CONTACT US, and
1278 we will include a separate definition corresponding to the old Update
1279 ES. Note that because of the change to the ASN.1 of the
1280 TaskPackageRecordStructure we cannot define a single structure that
1281 will support both versions.
1283 * Added const modifier to buffer parameter for some ODR/BER encoding
1284 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1285 completeWAIS, odr_dumpBER.
1287 Fixed bug in client.c which caused a crash when a scanResponse didn't
1288 contain positionOfTerm.
1290 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1291 * will cause an error in a client if a non-YAZ target sends both a
1292 * list of Scan entries and non-surrogate diagnostics.
1294 Retrieval module enhancements. Tag sets may be typed in the reference
1295 to it. From the .abs-file the "tagset" directive takes a third optional
1296 integer type for the tag set referenced. From a .tag-file the "include"
1297 directive takes a third optional type as well. The old "type" directive
1298 in the tag set itself is still recognized but acts as the default type
1301 Backend interface change. Individual Scan terms returned from bend_scan
1302 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1303 in include/backend.h.
1305 Retrieval module enhancements. Multiple tag sets and attribute sets may
1306 be specified in abstract syntax specs. Revised the error/warning for
1307 logging messages reported by the retrieval module when reading the
1310 Object Identifier system (oid_..) changed. The API is backwards
1311 compatible but the oid-routines now allocates new OID's when needed.
1312 Raw OID's may be specified in oid_getvalbyname.
1314 YAZ now uses GNU configure to generate Makefile(s).
1316 * Minor changes in some of the member names of DeleteResultSetRequest and
1317 DeleteResultSetResponse. See include/proto.h.
1319 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1320 and added member 'languages' in TargetInfo (which was missing).
1322 Changed the way attribute sets are handled in the retrieval
1323 module. These are now cached, just like the abstract syntaxes
1326 Changed YAZ so that it links with compiled ASN.1.
1328 Added Explain-schema definitions and mapping routines. The following
1329 Explain categories have been implemented: AttributeDetails,
1330 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1332 Fixed minor bug in Windows version of Server Library.
1334 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1336 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1338 Added EXTERNAL: UNIverse Resource Report (non-standard).
1340 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1341 ENUMERATED and SET OF.
1343 * Added 'const' to some of the char pointer arguments for the
1344 functions, data1_read_node, data1_getelementbytagname,
1345 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1348 Fixed bug in data1_insert_taggeddata - the last_child member of
1349 parent wasn't initialised.
1351 * Changed data1_read_record and data1_read_node so that the supplied
1352 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1353 doesn't refer to any parts of the "SGML"-buffer.
1355 Fixed bug in server library (Windows version of statserv_remove).
1357 * Changed code so that it compiles as C++. The type definition
1358 of Odr_fun which is a member of Odr_arm was changed. The result is,
1359 that an explicit typecast is needed for the fun pointer when
1360 using Odr_arm - as in:
1361 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1363 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1365 Implemented the new structured date and time definition as approved
1366 by the ZIG. Added schemaId element to the specificTag in Espec-1
1367 (also approved at the last ZIG). Thanks to RVDM.
1369 Added some Object identifiers (RVDM).
1371 Changed the Update Extended Service (RVDM).
1373 Added command "refid" to client which specifies referenceId for
1374 the following requests.
1376 Implemented extended service handling for server. See ztest.c
1377 for an example as well as backend.h. New handlers are registerd
1378 in the Init handler.
1380 * Changed interface for sort in server.
1382 Added new members to statserv_options_block. It allows a server
1383 to read options from another source than just the command line. Thanks
1384 to Charles Woodfield.
1386 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1387 renamed to zboolean. Some C++ compilers complained about the name.
1389 Minor changes to gils.abs. Added index 's' (sort) on title
1390 and date/time-last-modified.
1392 --- 1.4pl2 1998/1/30
1394 Fixed bug in server library regarding inetd mode (-i). This bug
1395 was introduced by release 1.4.
1397 --- 1.4pl1 1998/1/29
1399 Added sort facility in client and backend server interface.
1401 Fixed problem with dependencies in Makefile(s).
1403 Fixed bugs for encoders/decoders of extended services and
1406 Implemented sub-tree feature for schemas. Sub-trees are
1407 referenced in *.abs-files. See explain.abs for an example
1408 of the use of this feature.
1410 Modified bib1.att; local attributes for ANY didn't include
1411 ANY itself (only affects use of the retrieval module).
1413 Fixed bug in plain SGML reader in function data1_read_node:
1414 tags with prefix "var" was incorrectly interpreted as variants.
1416 Added feature "sub-schemas" to enable references to - and definitions
1417 of - group of elements.
1419 * Removed member parent from type data1_element (in data1.h).
1421 Implemented function odr_nullval() that returns the value of
1424 * Removed member num_children from data1_node (in data1.h).
1426 Made NT service interface part of the server library. The
1427 function statserv_main uses the NT service when required and
1428 calls the statserv_start / statserv_close routines.
1430 Routine zget_SearchRequest and zget_PresentRequest fills
1431 resultSetName/Id member with "default" instead of "Default".
1433 Fixed memory leak in server. Request queue member wasn't freed.
1435 Fixed nmem_exit so that memory is freed.
1439 Revised the CCL parser utility to be thread safe.
1441 Added function, oid_ent_to_oid, to replace the function
1442 oid_getoidbyent, which is not thread safe.
1444 * Added nmem_init and nmem_exit to initialize and release
1445 NMEM resources. Function nmem_init should be called once in the
1446 initial thread before NMEM/ODR is used. statserv.c and client.c
1447 have been changed accordingly. The change was necessary to make
1448 NMEM thread safe. The NMEM memory pool is shared amongst threads
1449 in a process. Unix-based applications will still work fine without
1452 Added NT Services interface for the the Z39.50 (statserv) Server.
1453 Refer to the ztest.c source on the usage.
1455 Windows 95/NT port using MSVC5.0. Project files are included in the
1458 * Defined new 'global' handle for the retrieval (data1) system. The
1459 new handled, data1_handle, describes the state of the data1 system.
1460 This handle is passed as first argument to virtually all
1461 data1 related routines. The functions data1_create and data1_destroy
1462 creates and destroys a data1 handle respectively.
1464 Added ODR encode stream member to all backend request structures
1465 init, search, scan etc. This stream should be used to allocate all
1466 memory used for the response when thread safe operation is needed.
1468 Changed the comstack utility, cs_addstr, to be thread safe. The
1469 returned hostname string returned by the function is now part the
1472 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1473 function. The cs_straddr takes a COMSTACK handle as argument, so this
1474 function must be used after cs_create and before bind/connect.
1475 This function is thread safe.
1477 Moved test server to 'ztest' directory - generic server code still
1478 in 'server' directory.
1480 Made prefix query (pquery.c) utility thread safe.
1482 Added new function modifier YAZ_EXPORT to 'export' public DLL
1483 functions when using windows (see include/yconfig.h).
1485 Added definitions to the OID database (util/oid.c) (RVDM).
1487 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1489 Added call to ccl_rpn_delete in client program.
1491 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1492 release of RPN structure.
1494 Added support for C++, headers uses extern "C" for public definitions.
1495 With input from RVDM.
1497 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1498 Thanks to Ronald van der Meer (RVDM).
1500 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1502 Added support for private extensions to the OID database
1503 (oid_setprivateoids()). Thanks to RVDM.
1505 Added optional, physical ANY (key replication)
1507 Fixed null-reference problem in GRS-1 output filter.
1509 Proximity operator added to Prefix Query Format (PQF).
1511 In test client command "base" accepts multiple databases.
1513 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1517 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1519 Smallish bug-fixes in the new encoders/decoders (explain).
1521 Bug fixed in DeleteRequest.
1523 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1525 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1527 Added SOIF syntax (using private OID for now) to retrieval module and client.
1529 Added Update extended service.
1531 Added SearchResult-1 additional info structure.
1533 Added optional CCL (ISO8777) interpreter as separate module. Available
1536 --- 1.2 1996/6/10 (1st anniversary release)
1538 Added Summary record syntax. Lightly tested.
1540 Added OPAC record syntax. Untested.
1542 Added ResourceReport service encoders/decoders. Untested.
1544 Fixed bug in z_Unit - wrong tagging on unitSystem.
1546 Fixed bug in the DiagRecs decoder.
1548 Added options for max PDU size and session timeout to frontend-server.
1550 Added documentation of query-language parsers and other supporting utilities.
1552 [frontend-server] Added Attribute set to the bend_scanrequest API.
1554 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1555 surrogate diagnostics were generated.
1557 [retrieval] Allow multiple local values for attribute.
1559 [retrieval] Allow multiple attributes per element in .abs files. index type.
1561 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1563 --- 1.1pl2 1996/4/10
1565 Minor changes, mostly specific to Zebra's requirements (retrieval)
1569 Repaired bug in frontend server when running multiple listening
1570 endpoints in dynamic mode.
1572 z_External() now won't break if a known, ASN.1 value comes encapsulated
1573 in an octet-string. The value will pass through unmodified in an Odr_oct.
1575 Added a bit of code to the demo client to decode & display
1576 ASN.1-structured records represented in the octet-aligned branch of
1577 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1579 Added z_ext_getentbyref() to the ASN module. Doc updated.
1581 * Completed the SCAN definition in the ASN module. This may break SCAN
1582 code based on older YAZ-versions at compile-time. The fix is easy -
1585 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1586 under the SCAN definition. Remember to initialize this, server-people.
1588 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1589 that this does not extend to ODR and ASN.
1591 Comstack allows insertion of established socket (primarily for
1592 inetd-operation of servers). Doc updated.
1594 Front-end server can now start from the inetd in TCP mode. Doc
1597 --- 1.0pl4 1996/1/24
1601 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1602 the rank and record number.
1604 Adjustments to the frontend server.
1606 Fixed diagnostic BER dumper. It ignored the file argument.
1610 Various changes to retrieval module.
1612 Changed the union discriminators of the protocol files from enums to
1613 ints paired with #defines.
1615 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1618 *Changed operator in the RPN structure to 'roperator', again to avoid a
1621 Fixed problems in Explain decoders/encoders.
1623 --- 1.0pl2 1995/12/6
1625 Memory bug in log module fixed.
1627 --- 1.0pl1 1995/12/5
1629 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1631 Bug in Explain DatabaseInfo module fixed.
1633 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1637 The shift to v1.0 signals that we now consider the *core* functionality
1638 of YAZ reasonably stable (the core being more or less equivalent to
1639 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1640 tested (Explain not at all - though that will happen soonish).
1642 Minor changes to code to support Windows port.
1644 Various minor changes after we're getting to use GRS-1 & co. more.
1646 Added Espec-1 format.
1648 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1649 of the protocol and it cannot be selected when encoding (maps into 'string'
1650 when decoding). Needed to talk to some servers.
1652 Demo client can request simple element set names.
1654 Added Diagnostic Format encoders/decoders.
1656 Added simple Close handling to frontend server (no hooks for resource
1657 reporting yet), and demonstration client.
1659 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1661 --- 1.0b3 1995/08/24
1663 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1664 handled incorrectly when records were requested in the searchResponse. This
1665 will only affect you if you use the frontend-server.
1667 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1668 Test-client will ask for and print GRS1. Ztest will return dummy records
1671 Added Explain encoders/decoders to the service-level API. Untested.
1673 Added Extended Services: Item Order encoders and decoders to the Service-
1674 level API. Untested. We could use a recent copy of the pertinent bits
1675 of the ILL protocol to add those bits.
1677 Added diagnostic format 1 encoders/decoders to the service-level API.
1680 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1681 odr_cons.c, which causes a more correct output.
1683 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1684 was always set to 0 when no records were requested in the searchRequest.
1686 * Added better external-handling. This shouldn't harm old code that
1687 *encodes* externals. It can break code that looks for a
1688 'single-ASN1-type' representation, since those types that are known
1689 are now decoded immediately. Look at the SUTRS sample code in
1690 seshigh.c and client.c. Documentation updated.
1692 Handling of structured records in bend_fetchresponse. Length -1 marks
1693 structured record, type is deduced from format field.
1695 --- 1.0b2 1995/06/27
1696 Fairly quick maintenance release to add SUTRS support.
1698 Fixed handling of SUTRS records in the demonstration client.
1700 * Added format field to the bend_fetchrequest and bend_fetchresponce
1701 structures of the backend API (frontend server). When the record is
1702 returned, the value of the format field is mapped to an OID. The
1703 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1704 of the record. The special value VAL_NONE in the bend_request means
1705 that no specific format was requested by the client. Documentation
1706 updated accordingly. Test server (ztest) will return a fixed dummy
1707 SUTRS record if your client requests SUTRS.
1709 Documentation updated accordingly.
1711 You can now set external libraries and RANLIB support in the top-level
1715 First public release.
