2 For SRW, accept application/soap+xml as content-type for SOAP msg.
6 Updated Windows package to include yazd.dll + yazd.lib for the
9 If the environment variable YAZ_LOG is set, then it is used as a
10 string indicating the default level of logging to use if not
11 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
12 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
13 used as before. So, for example, to omit warnings from YAZ logging,
16 cql_transform() now map structure and other attributes before indexes,
17 so that index-specific structures and other attributes can override
18 defaults. So now a combination of mapping specifications such as:
20 index.dc.date = 1=date-modified 4=5
23 cql_transform() now also respects the "always" mapping specification,
24 which establishes an initial set of attributes to be used for all
25 terms except where overridden by more specific attributes associated
26 with the index, relation or modifier.
28 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
29 which mode to use; one of "post", "get" or "soap" (SRW, default).
31 Fixes for yaz_iconv routines: changed trie-based character set conversions
32 to use only non-negative values for bit fields due to Sun's C compiler not
33 supporting negative values.
35 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
36 sequences where not read correctly. Fix by Rustam Usmanov.
38 Updated win/makefile to use options, settings which makes things
39 compile with VS C 2005.
43 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
45 In ZOOM socket code, use select instead of poll on MacOSX.
47 ZOOM-C now support client-side compilation of CQL into RPN that is
48 sent to the server, enabling CQL to be used against all Z39.50
49 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
50 ZOOM_query object, and submit it using ZOOM_connection_search().
51 The CQL-to-RPN translation uses a configuration file, the name of
52 which must be specified in the Connection's "cqlfile" option.
54 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
55 function, which takes as its start-term parameter a ZOOM_query object
56 (which may have had either CQL or RPN set into it).
61 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
62 GFS to support this as well. Backend handler, bend_srw_update, does the
63 update work. Code contributed by Ko van der Sloot.
65 Allow retrieval of Search Result-1 information in ZOOM by the use of
66 options that are attached to a result set. ZOOM documentation updated
69 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
70 UTF-8 conversion. Patch by Raj Patel.
72 Added option -m to GFS to control formatting of timestamps in log file.
74 Added 'exit' as synonym for 'quit' in yaz-client
76 Added support for specifying SRW resultSetId + resultSetIdleTime in a
77 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
78 for the new members. Patch by Ko van der Sloot.
80 Added support for SRU POST. It is supported for content-type
81 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
83 Do not build the separate Multi-threaded (MT) library libyazthread.la.
84 Instead make the library libyaz.la multi-threaded. Threading as a whole
85 can still be disabled by configure option --disable-threads. Previosly,
86 with older GLIBCs there were problems with MT libs under Apache. This
87 has now been fixed a long time ago.
89 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
92 CQL module modified to be case insensitive for relations/indexes/operations.
94 Fixed bug in CQL transform code: incorrect value relationModifieder
97 Added 'show all' command for yaz-client which retrieves all results
100 Added new yaz-client, xmles, which takes a (private) OID and
101 a document to be sent as an extended service request.
103 Describe new yaz-client commands wait_response and set_auto_wait.
105 Increase TCP/IP listener backlog from 3 (which I am guessing was
106 copied from the SunOS manual entry way back when) so SOMAXCONN, so
107 that the socket will queue as many incoming connections as it's able
108 to handle ongoing connections. In other words, it will never now
109 refuse a connection that it would be able to handle merely because
110 it's not got around to accepting() enough of the pending connections
111 yet. This is the behaviour anyway under Linux, where the listen()
112 argument is ignored; but not under BSD and on systems such as
113 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
114 YAZ-based servers should now be uniform across operating systems in
117 yaz-marcdump uses 64-bit file access on some systems. This is enabled
118 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
119 This allows yaz-marcdump to read large MARC batches (>2 GB).
121 Modified all YAZ source files - except the source which is auto-generated
122 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
125 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
126 corresponding to the existing *_setl() function. These allow option
127 values containing arbitrary valuues.
129 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
130 ZOOM_resultset_sort() in new applications. Its behaviour is identical
131 except that it returns an indicator of whether or not the sort
132 criterion was accepted (0 for OK, -1 for invalid).
136 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
137 MARC output rather than returning "new" buffer.
139 yaz-client warns about unknown init options.
141 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
145 Added support for SRW sort in Generic Frontend Server. Patch
146 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
147 sortKeys - or NULL if none is provided.
149 Fixed bug #307: It was impossible to specify indefinite/no timeout
150 for ZOOM_event. Special timeout value -1 now means indefinite timeout
153 Added support for multiple languages and charsets to be specified in
154 ZOOM. Each charset/language is separated by a blank. If negotiation is
155 in effect in init-response, Option
156 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
157 Code based on patch by Vasiliy Osadchuk.
159 Fixed bug #306: infinite recursion that occurred when calling
160 yaz_log_level_init as the first call (before other log level or
163 Fixed bug in scan handling in front end server: if preferred-Position-In-
164 Response was non-present, a NULL pointer referece was performed.
168 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
169 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
170 now defined for all those error codes. So instead of putting 109 in
171 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
172 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
174 Modified the yaz-marcdump utility to skip garbage bytes between MARC
177 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
179 Program yaz-client now exits and produces an error message if multiple
180 Z39.50 servers are specified on the command line (none or one allowed
183 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
188 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
190 Fixed bug #272: Preserve spacing for CCL terms.
194 Added support for virtual hosts and multiple backend servers for
195 the YAZ frontend server. The configution is XML based and
196 support specificition of CQL to RPN mappings and explain information.
197 See section "Virtual Hosts" in the YAZ manual.
199 Extended OPAC display utility. OPAC display utility renders
200 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
201 to supplement yaz_marc_decode_wrbuf.
203 Fixed a bug in MARC decoder that could caused it to crash for some
204 invalid MARC records. More diagnostics and warnings where added in
205 XML output (warnings, etc are stored in comments).
207 --- 2.0.34 2005/02/08
209 Fixes for UNIX domain sockets. Bug #261.
211 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
213 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
214 Added yaz_marc_subfield_str which defines subfield lead string which is
215 used in YAZ_MARC_LINE format. Default string is blank+$. Added
216 yaz_marc_endline_str which defines end of fields string used in
217 YAZ_MARC_LINE format. Default string is newline.
219 Experimental support for MarcXChange. This format can be produced
220 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
221 http://www.bs.dk/standards/MarcXchange.xsd
223 Added yaz-client commands scansize that sets maximum number of
224 entries to be returned by scan.
226 --- 2.0.32 2005/01/11
228 Added support for SRW scan in yaz-client and Generic Frontend Server.
230 * Added whereInList member to SRW Scan Term.
232 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
234 Fixed NMEM system to return aligned blocks on the smallest boundaries
235 that are suitably aligned for all possible types on the particular
236 architecture YAZ is being built for.
238 --- 2.0.30 2005/01/04
240 Fixed numerious warnings that was issued with newer versions of GCC.
242 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
243 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
246 Make YAZ Generic Frontend Server slightly faster.
248 Enhance (and reduce) logging for Generic Frontend Server.
250 Revert YAZ log system so that it flushes every write operation
251 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
253 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
254 instead of LOG_, due to name clash with syslog(3). LOG_ are still
255 present. New applications should define YAZ_USE_NEW_LOG=1 - this
256 will effectively disable old definitions.
258 --- 2.0.28 2004/11/09
260 Added yaz_log_time_format which specifies log format using
263 Added yaz_log_module_level which returns mask for a module. Value
264 is non-zero mask a if module is enabled; zero if disabled.
266 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
267 in include/yaz/cql.h.
269 Fixed bug #176: Dont throw diagnostics on empty SRU args.
271 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
273 Fixed bug #172: RPM builds does not enable SSL.
275 Doxyfile.in part of dist. Doxyfile generated by configure.
277 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
278 are given and the corresponding component does not exist.
280 Extend CCL documentation in YAZ reference. Describe r=r.
282 --- 2.0.26 2004/10/01
284 Fixed MARC->MARCXML conversion to properly deal with
285 fields, subfields, indicators having non-ASCII characters.
287 Fixed MARC->MARCXML conversion so that ASCII control characters
288 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
291 Added YAZ GFS support for conversion from Z39.50 surrogate
292 diagnostics to SRW surrogate diagnostics.
294 Bug fix: YAZ GFS did not return schema in explainResponse.
296 --- 2.0.25 2004/09/30
298 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
299 now converts recordSchema to elementSetName as well as schema URI.
301 Fixed bug in COMSTACK that prevented HTTP request packages from being
304 --- 2.0.24 2004/09/29
306 Added CCL facility r=r "range" which is similar to r=o "ordered" but
307 does not require white-space before and after the dash in a range, e.g.
308 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
311 Fixed a few AC_TRY_LINK configure tests that did not operate properly
312 due to new GCC removing "redundant" code.
314 Added yaz-client commands scanpos and scanstep that sets preferred
315 position and step-size for scan.
317 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
319 Added CCL utility ccl_qual_buf which parses one or more CCL
320 spec lines in a buffer.
322 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
323 of name and value - ignoring empty lines and comments.
325 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
327 Added odr_get_element_path which returns current element path for an
328 ODR handle. This utility is useful in error handling or user-defined
331 Added ODR_PRINT utility odr_set_stream which is is a more generic
332 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
333 to a write function and pointer to close function. The close function - if
334 non-NULL - will be called during odr_destroy.
336 Fixed bug in CCL parser where truncation char was not removed from
337 right side when truncation=both was in effect.
339 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
342 --- 2.0.23 2004/08/11
344 Fix buffer overrun in CQL parser when dealing with proximity (%).
346 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
347 to UTF-8/UCS conversion is now only based on codetables.xml.
349 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
351 --- 2.0.22 2004/08/06
353 Add support for more "commit changes" in ZOOM (uses Extended Services).
355 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
358 Yet another small fix for configure of SSL.
360 --- 2.0.21 2004/05/14
362 Fix SSL libs for configure when --with-openssl=DIR is given.
364 --- 2.0.20 2004/05/10
366 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
368 SSL comstack now uses yaz.pem certificate file on server side
369 by default. Certificate filename can be configured by calling
370 comstack function cs_set_ssl_certificate_file before cs_bind is used.
372 Fix bug regarding multiple calls to ZOOM_connection_connect.
374 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
376 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
377 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
379 ZOOM now allows inspection of X509 peer certificate for verification.
380 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
382 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
383 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
384 as "modular" but it simplifies things.
386 Added cs_get_peer_certificate to that returns peer X509 PEM.
388 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
389 NULL if SSL is unavailable.
391 Documentation about MARC decoding tools.
393 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
395 --- 2.0.19 2004/03/30
397 Rename CHANGELOG to NEWS to follow GNU style packing.
399 Fix bug with missing initialization of member in init_diagnostics.
400 This bug affects threaded version of GFS server.
402 --- 2.0.18 2004/03/20
404 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
407 Ensure zlib.dll is packed with Windows install.
409 --- 2.0.17 2004/03/17
411 Fix encoding of xsd:string to use text instead of CDATA.
413 Fix endless loop in CQL parser with unbalanced ".
415 Use a more compact way to store MARC-8 conversion tables.
417 --- 2.0.16 2004/03/16 Debian only
419 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
422 Update CQL parser to use new CQL 1.1 modifiers for booleans and
427 --- 2.0.15 2004/03/01
429 Another fix for decoding of XML packed records.
431 --- 2.0.14 2004/02/25
433 Fixes for Chunked encoding. White space not ignored after length spec.
435 Update NS and use default NS for SRW diagnostic elements.
437 --- 2.0.13 2004/02/23
439 Implement ZOOM_resultset_cache_reset which resets record cache.
441 Implement ZOOM_resultset_sort which sorts a result set.
443 Implement chunked HTTP transfer.
445 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
447 --- 2.0.12 2004/02/16
449 Added member 'schema' to bend_explain_rr structure so that backend
450 can specify explain record identifier. Defaults to Zeerex 2.0.
452 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
454 --- 2.0.11 2004/02/16
456 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
459 Added init command for yaz-client which sends "extra" init request.
461 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
462 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
464 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
466 Make ZOOM error code for "invalid query".
468 Fixed compilation for SSL which wasn't properly enabled for all platforms.
470 --- 2.0.10 2004/02/05
472 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
475 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
477 Added option -p <file> to make Generic Frontend Server to write PID file.
479 Added option -D to put Generic Frontend Server in background on its own.
481 Make ZOOM C recognize option "password". If unset, "pass" is used
482 (for backwards compatibility).
484 Fixed a bug in Generic Frontend Server that could make it crash if a
485 client sets characterSetNegotation bit, but didn't pass negotiation stuff
488 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
489 Must be issued before open, in order to be in effect.
491 --- 2.0.9-6 2004/01/12 Debian/Windows
493 Make the SRU server more picky WRT unknown params, etc.
495 Bug fix: ZOOM scan response didn't return displayTerm - when present.
497 New YAZ client command, options, that sets Z39.50 options.
499 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
500 options from a string of tokens (one token for each option bit).
502 Update SRW diagnostic code messages.
504 --- 2.0.9-5 2004/01/07 Debian/Windows
506 Handle user defined stylesheet for SRW/SRU.
508 --- 2.0.9-4 2004/01/06 Debian/Windows
510 Fix bug in decoding of Content-Length.
512 --- 2.0.9-3 2004/01/06 Debian/Windows
514 Fix a bug with decoding of XML packed records.
516 --- 2.0.9-2 2004/01/05 Debian only
518 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
520 Fix bug in SRW/SRU diagnostics decoding.
524 Fixed bug in Generic Frontend Server which could drop records exceeding
525 preferred message size. Reported and fixed by Irina Dijour.
527 Fixed calculation of package size for structured records in Generic
528 Frontend Server. Reported and fixed by Irina Dijour.
530 Fixed namespace for SRW/SRU diagnostics.
532 Fixed SEGV in yaz-client that occured for HTTP connection errors.
536 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
537 this version is incompatible with version 1.0 and older YAZ SRW/SRU
540 CQL changes to reflect recent changes to the specification:
541 * Documentation talks about context sets instead of index sets.
542 * Documentation talks about indexes instead of qualifiers.
543 * The CQL-to-PQF transformer's configuration file now uses
544 "index.set.name = <attributes>" instead of the old form
545 "qualifier.set.name = <attributes>". (Both forms are still
546 understood but the latter is deprecated.)
547 * CQL terms with no explicit index specified are now interpreted as
548 cql.serverChoice instead of srw.serverChoice (which of course
549 behaves exactly the same.)
553 MARC conversion can now generate ISO2709 output in another
554 character set. yaz-marcdump uses this facility if you invoke it
557 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
558 functions from there can be used from C++.
562 Frontend server now transfers memory from decoded packages to stream
565 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
566 references to show up.
568 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
569 the ZOOM Abstract API. The older names for the same options are still
570 also supported for the benefit of old applications.
572 ZOOM-C supports "implementationId" and "implementationVersion" options
573 to go along with "implementationName". These allow the user code to
574 specify identification strings to be sent to servers.
575 Add OID for the new ExtLite attribute set.
577 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
578 as requested/supplid by Ere Maijala <ere@atp.fi>
580 For generic frontend server, reverse the order of
581 "toolkit-supplied / application-supplied" strings sent as implementationId,
582 Name and Version. Also, remove the spaces around the slash. This brings
583 the GFS in line with the behaviour of ZOOM-C on the client side.
585 Add function ZOOM_scanset_display_term.
587 yaz-client shows scan displayTerm if present.
589 Utility yaz-iconv is now installed by default along with the man page
592 Extend configure check for OpenSSL to use pkg-config where available (such
595 Incorporate patch by Morten Bogeskov which allows a Unix file socket
596 server to specify uid/gid/mask for socket using the format
597 unix:[user=uid,][group=gid,][umask=mask,]file=path
598 If file= is omitted the existing format is assumed, e.g.
600 in which case the mask is 0666 (rw for everybody).
602 Major restructure of YAZ source. All source in libyaz is in src directory.
603 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
604 util (utility programs such as ASN.1 compiler, yaz-marcdump).
606 Added man page for utility yaz-marcdump (used to be called marcdump).
607 yaz-marcdump is installed by 'make install'.
609 Fixed a memory leak in Generic Frontend Server that occurred when decoding
610 of incoming package failed.
612 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
614 Change prototype of odr_perror: add const to message string.
616 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
618 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
619 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
620 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
621 DNS lookup. There should not be any compatibility problems with this
622 assuming that blocking=1 or 0 is used.
624 Fix bad reference in UNIX comstack in function cs_addrstr.
626 Fix for compilation on AIX.
628 The generic front-end server (server/seshigh.c) now supports returning
629 Init diagnostics to the client in User-information-field, in
630 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
635 Allow any CQL relation (not just all,any,exact,scr).
637 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
638 that features the same UI.
640 Implemented command update0 in YAZ client which is equivalent to
641 update but uses old of Ext Update ASN.1.
643 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
644 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
645 Previously no OID was used for this info.
647 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
648 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
649 returns 'malformed search term' otherwise.
651 SortResponse member resultCount now set to NULL in sort handler of
654 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
657 Add three new utility functions for translating OIDs between various
658 formats -- symbolic name such as "Usmarc", minus-1-terminated int
659 arrays and dotted strings such as "1.2.840.10003.9.5.1":
660 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
661 char *oid_to_dotstring(const int *oid, char *oidbuf);
662 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
664 Reverted modifications for ES Update definition for z_IU0Update
665 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
666 is back to YAZ 2.0.2.
668 String value attributes for CCL parser.
670 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
671 which their FirstSearch server returns in Init responses, sometimes
672 carrying useful diagnostic information when Init fails. This has the
673 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
674 "z39.50/oclcui.asn", where its definition is somewhat different from
675 what OCLC document on their web-site, as required to interoperate with
678 Support for anonymous authentication in yaz-client. Use the command
681 * Fix the OID of the Index Data-local "admin" Extended Service from
682 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
683 the 1000, which indicates a locally-defined OID, was a mistake.
687 Fix CCL directive @case handling so that it affects string match for
688 both CCL keywords and qualifiers.
690 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
691 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
692 Decoder has been updated with ASN.1 changes as listed in
693 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
694 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
695 z_IUUpdate, remains unchanged.
697 ZOOM_record_get may now return a record in a specific character set.
698 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
699 "from" is the character set of record as returned by target. "to" is
700 the character set to be returned. If omitted, "to" is UTF-8.
702 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
704 New ODR utility, odr_getelement, which returns name of element for
705 which encoding/decoding failed.
707 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
708 in cases where a required element was omitted.
710 Bug fix: some MARC8 sequences were not converted.
712 New ZOOM option "step" which specifies number of records to be
713 retrieved in one chunk. Used in conjunction with "start" and "count".
715 SRW support for yaz-client. Use scheme http: to use it, e.g.
718 yaz-client no longer does (un)intelligent character set conversions
719 by default. Can be enabled with charset and marc_charset commands.
721 xmalloc trace fix for 64-bit systems such as DEC alpha.
723 Solaris 2.6 compile fix.
725 New function, cql_strerror() translates SRW error codes, as returned
726 by cql_transform_error(), into human-readable English strings. Used
727 in yaz-client diagnostics when appropriate.
729 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
730 converts it into a type-1 query which is sent to the server. This
731 makes CQL available for use with all Z-servers, as opposed to the tiny
732 minority that can handle CQL queries themselves.
736 New Debian package layout similar to the Redhat Package layout.
738 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
739 and search result respectively.
743 Redhat package is now several packages: libyaz (runtime libraries),
744 libyaz-devel (development and documentation, and yaz (utility programs).
745 Package spec file by Morten Bøgeskov.
747 New member 'schema' in struct bend_fetch_rr which the name of requested
748 schema (SRW/SRU) for record (or NULL if none was given). The fetch
749 handler MAY set this to reflect the schema of the returned record.
751 New member 'display_term' in struct scan_entry. GFS now sets member entries
752 and allocates scan entries to be filled by user scan handler. In previous
753 version, entries member was allocated by the scan handler. That still works,
754 but the GFS will ignore member display_term - assuming it was NOT set by
755 the handler. The fact that the GFS now allocates the entries both allows
756 for new members and makes a scan handler easier to write.
758 Fix CQL lex buffer overflow.
760 SRW/SRU recordPacking. For SRW default recordPacking is string. For
761 SRU default recordPacking is string.
763 SRU protocol support for frontend server.
765 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
767 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
769 Added scan for the ZOOM shell (zoomsh).
773 * String Identifers for Schemas (Amendment 5).
774 http://lcweb.loc.gov/z3950/agency/amend/am5.html
775 Old definition for schema
776 Odr_oid *schema; /* OPT */
781 Z_InternationalString *uri;
782 #define Z_Schema_oid 1
783 #define Z_Schema_uri 2
786 * resultCount parameter to Sort Response (Amendment 1).
787 http://lcweb.loc.gov/z3950/agency/amend/am1.html
789 Support for SRW 1.0 over HTTP. This is an optional feature and
790 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
793 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
794 on the same port. SRW SearchRetrieveRequests are mapped
795 to bend_init,bend_search,bend_fetch,bend_close.
797 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
799 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
800 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
802 ZOOM connections are SRW based if schem http is used for hostname
803 in connect, e.g. z = ZOOM_connection_new("http://myserver");
804 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
806 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
807 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
808 distance=n, order=true/false, relation=le, prox unit=word. If
809 n is omitted, distance 1 is used.
811 Fixed problem with C compiler include path in wrong order.
813 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
814 on Solaris. Patch from Ko van der Sloot.
816 New MARC decode API. All new functions operate on a yaz_marc_t
817 handle. The most important new functions are: yaz_marc_create,
818 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
819 decode and destroy respectively. Decoder can produce formats
820 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
821 include/yaz/marcdisp.h.
823 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
824 to UTF-8, UCS-32, wchar_t or Latin-1.
826 * Prototypes for yaz_iconv_-functions moved to separate header
827 include/yaz/yaz-iconv.h.
829 Make a few private functions 'static' in unix.c. This prevents
830 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
832 For ZOOM connection, the options targetImplementation{Id,Name,Version}
833 are set when Init Response is received.
835 New function ZOOM_connection_error_x similar to ZOOM_connection_error
836 but returns diagnostic set as well.
838 New function yaz_strerror which is a portable wrapper for
839 strerror/strerror_r/GetLastMessage.
841 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
842 is returned for MARC. If type is "oai", then OAI MARC is returned.
844 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
849 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
851 Fix bad race conditions on SIGTERM and terminate gracefully in
854 Move retrieval (data1) module to Zebra since nobody seems to be
857 Add GRS-1 render for ZOOM using same format as yaz-client.
861 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
863 Fix broken ESpec handling in data1 module.
865 SGML reader parses comments and makes them part of the data1 tree.
867 Added several type casts so that YAZ compiles as C++ code.
869 ZOOM didn't handle PDU encoding failures properly.
871 Added more Bib-1 diagnostics (approved extensions).
873 GNU configure: better check for iconv.
875 More portable use of accept, getpeername. Check for socklen_t. Use
876 int/size_t if socklen_t is not defined.
880 PQF parser rejects bad queries - including those with extra
881 characters in them. PQF parser used to silently ignore that.
882 Cleaner API for PQF added, which allows you to get detailed
883 error information for bad queries (see yaz/pquery.h).
885 Fixed bug in ZOOM_record_get for type "database".
887 Implemented mini iconv library supporting conversions between
888 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
890 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
894 Fixed ZOOM C record cache so that preferredRecordSyntax and
895 elementSetName is used to check for already fetched records.
899 Added three members in bend_initrequest structure to facilitate
900 character set negotiation.
902 Fixed a bug in frontend server that could cause indefinite
903 loops under rare conditions.
905 Revised character set utilities (charneg.h) so that encoding
906 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
908 For PQF, directive @term <type> sets term type for Scan/Search.
909 Here <type> is general, string, numeric, null. The term type
910 is inherited - just like @attr.
912 New call odr_set_charset that sets character set conversion for
913 international-strings on a ODR stream. Prototype is:
914 int odr_set_charset(ODR o, const char *to, const char *from);
915 The InternationalString is still represented as C string in YAZ
916 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
917 won't). On the protocol level, you can use any encoding.
919 Support for UNIX sockets in ZOOM.
921 Solaris recv sometimes returns errno == ENOENT. It is treated as
922 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
924 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
925 both client and server. Code by Morten Bøgeskov.
929 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
930 that they can be used directly from Visual Basic. You must recompile
931 your windows APP if you're using ZOOM.
933 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
934 Commands "lang" and "charset" sets language and character set respectively.
935 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
936 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
938 Attributes from multiple CCL fields may be OR'ed rather than merged
939 using directive "@field or". Fields are still merged by default -
940 equivalent to "@field merge".
942 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
945 Fixed bug in zget for parameter ExtendedServicesResponse.
951 Added PQF feature: '@attr type=value' may be written as '@type=value'.
953 Client displays USR.1:SearchResult-1 (hits per term).
955 Additional Search Info for search in Generic Frontend Server.
957 Fixed CCL parsing of "field=s".
959 WIN32 installer - using the excellent NSIS software from nullsoft.
961 Fixed CCL parsing of "field = - <number>".
963 Added function yaz_marc_decode that decodes MARC for line mode
964 display or XML (similar to that used by JZKit).
966 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
967 Z39.50. But ISO/ILL was, however.
969 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
970 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
972 http://lcweb.loc.gov/z3950/agency/amend/am2.html
973 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
977 New YAZ client features: Command completion and new commands:
978 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
979 Code provided by Jacob Poulsen.
981 New call oid_trav, that visits all registered OIDs via callback.
983 Function ZOOM_record_get now returns const char pointer rather than
984 void pointer. It saves a lot of type casts.
986 For YAZ client, command "auth" now allows you to set authentication
987 in IdPass style. It is enabled when three tokens are given - order
988 is user, group and password.
990 Fix memory leaks in MARC record handling for ZOOM.
992 New option for YAZ client, -k <kilobytes> that sets
993 maximum record size. Similar to -k option for generic frontend
994 server and yaz-ztest.
996 More fixes for scan. Non-zero stepSize handled. OID's fixes.
998 Prefix query parser reports "fail" when bad attribute set is given.
1000 Fix in MARC decoder. Proximity logging. Fix for attribute set
1001 in scan handler for server. Patches by Shigeru Ishida.
1003 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1006 Configure option --with-openssl=<dir> now works when a directory is
1007 specified. Patch provided by Morten Bøgeskov.
1009 New option for YAZ client, -u <auth>, that sets authentication.
1011 ZOOM fix: error information was sometimes "missing", since error
1012 was cleared/reset too when it shouldn't.
1014 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1016 --- 1.8.4 2002/01/04
1018 Scan for ZOOM API. New object ZOOM_scanset. New functions
1019 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1020 ZOOM_scanset_destroy.
1022 New ZOOM function, ZOOM_connection_last_event, that returns type
1023 of last event (such as "receive data", "send data", "apdu received",
1026 New ZOOM option, schema, that specifies schema for retrieval.
1028 New CCL feature. Qualifiers can be aliases for one or more
1029 other qualifiers (if more than one is given, OR is used).
1031 ZOOM uses named result sets if target supports it.
1033 Two new YAZ client commands: . (dot, which sources a script of YAZ
1034 client commands), and ! (to execute shell command.). Implemented
1037 Working on Debian packages.
1039 --- 1.8.3 2001/11/19
1041 YAZ client enables named result sets only if target supports it.
1043 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1045 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1046 with key="host" to get same result.
1048 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1049 Function Z3950_resultset_record(s) returns references to records
1050 "owned" by resultset. To become owner use Z3950_record_clone.
1052 Function z_ext_record handles Extended Services. Thanks to
1055 --- 1.8.2 2001/11/12
1057 CCL Parser fix: ignore token comma when dealing with and-lists.
1059 Documentation updates for COMSTACK.
1061 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1062 Changed prototype Z3950_records. For some functions, int parameters
1063 were changed to size_t.
1065 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1068 New MARC decode/display function, marc_display_exl, which properly rejects
1069 non-ISO2709 records. YAZ client uses it.
1071 --- 1.8.1 2001/10/29
1073 Fix bug: local attribute set wasn't set correctly in PQF strings.
1077 * Old Z39.50 codecs no longer supported.
1079 Added ZOOM C binding. See http://zoom.z3950.org/
1081 Renamed states for COMSTACKs to avoid confusion with events.
1083 Implemented cs_look and proper cs_rcvconnect.
1085 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1087 Configure detects POSIX threads on OpenBSD.
1089 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1090 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1092 When error is returned from present handler, non-surrogate diagnostic
1093 is returned in present response (and fetch handler is no longer called).
1095 * Minor adjustments to pquery parser (PQF). Token characters may be
1096 escaped by using backslash (C-style).
1098 PQF parser allows string attribute values to be specified. For @attr,
1099 non-numeric characters after the equal-sign are treated as strings
1100 (e.g. @attr 9=title).
1102 CCL trunction character may be defined (@truncation in file)
1104 * function zget_ExtendedServicesRequest sets waitAction to
1105 waitIfPossible (was wait).
1107 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1110 CCL operator names may be set in field definition files (CCL_bibset).
1111 See ccl/bib1 for an example.
1113 Fixes in ASN.1 compiler for C++ compatibility.
1115 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1116 and "op_or" to avoid conflict with C++.
1118 Fixed problem with GNU readline detection on Redhat 7.0.
1120 Added step-size for Scan backend handler.
1122 Fixed bug that made the frontend server crash when no attribute
1123 set was specified for scan.
1125 Front-end server automatically switches to original working directory
1126 when installed as an NT service. Previously -w had to be specified to
1129 Added extended attributes for retrieval module (data1), so that data1
1130 records carry d1_readXML/SGML attributes. d1_read also supports
1131 null-data rules ( <tag/>)
1133 On UNIX when POSIX threads are available, a separate library libyazthread
1134 is created. Programmers should link with that library and the yaz library
1135 when using threads. The reason for the split was that some applications
1136 on Linux, such as Apache, doesn't work well when using shared objects that
1139 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1140 (or any frontend server) in SSL mode by specifying ssl: followed by
1141 address. Only tested on UNIX.
1143 Added feature for CCL module. Virtual structure s=al or s=ol generates
1144 and-list and or-list respectively instead of phrase search.
1148 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1149 log_mask_str. This was done to avoid name conflicts with other libraries
1150 (such as other PHP extensions).
1152 Added raw OID member for preferred record syntax (request_format_raw)
1153 and returned record syntax (output_format_raw) for backend fetch method.
1155 Config file yaz-config now accepts options so that it returns specific
1156 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1158 Shared library support for UNIX using GNU libtool.
1160 * Modified backend interface. Request/Response struct's replaced by
1161 one read/write C struct. For example bend_fetchrequest and
1162 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1163 Every handler - even search has to be registered in bend_init
1164 handler. This means that the YAZ library no longer refers to
1165 external functions and it makes it possible to make the whole
1166 thing a single DLL/SO.
1168 Added Segment handler for backend server.
1170 Added Zmbol/Zebra administrative functions to YAZ client.
1172 Threaded frontend server on UNIX (when POSIX Threads are available).
1173 Starting the server with option -T enables multi-threading.
1177 Added configure option --enable-comp/disable-comp to control use
1178 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1179 located in sub directory asn.
1181 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1182 in ${exec_prefix}/bin along with the other programs yaz-client and
1185 GNU automake used to maintain makefiles.
1187 Added several OID's.
1189 Changed retrieval module so that we can load records with no abstract
1190 syntax defined. Tagpaths in these records are fully composed of string
1193 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1197 On UNIX, the generated makefile now supports a proper 'make install'.
1198 The prefix can be set via GNU configure to set the install location
1199 (default is /usr/local).
1201 * YAZ programs client and ztest were renamed to yaz-client and
1202 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1203 locations, such as /usr/bin,/usr/local/bin,etc.
1205 * YAZ Header files were moved from include to include/yaz. YAZ Header
1206 files are referred to as include <yaz/log.h> rather than <log.h>.
1207 The YAZ include path (-I ..) is therefore the same as before. Programmers
1208 should update their #include statements or use -Ipath/include/yaz
1209 instead. The main motivation for doing this change is that YAZ header files
1210 can be installed in "standard" locations /usr/include,/usr/local/include
1211 without introducing conflicts, since ALL YAZ header files are stored
1212 in subdirectory yaz (under /usr/include for example).
1214 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1215 rather than project/workspace files. We switched because project files
1216 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1219 Changed name of logging function, logf, to yaz_log, to prevent name
1220 clash with some math-log functions. The YAZ header log.h defines logf
1221 to yaz_log (#define) so there should be no incompatibilities by this
1224 Added bend_start/bend_stop handlers for server. These handler are
1225 called on start/stop of server. For windows they are called whenever
1226 a service is started/stopped.
1228 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1229 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1230 in util/yc.tcl. The auto-generated C code structures are, in a few
1231 cases, incompatible with the old decoders. There are differences in the
1232 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1233 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1234 The preprocessor variable ASN_COMPILED is defined when the compiled
1235 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1236 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1237 wish to use the old encoders/decoders you can specify --disable-yc
1240 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1241 version so that it supports both new - and old version of DB Update
1243 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1244 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1245 change. The name parameter can be set to 0 in which no name is specified
1246 for the construction. The macros odr_implicit and odr_explicit sets name
1247 parameter to zero for the construction involved. New macros
1248 odr_implicit_tag and odr_explicit_tag are similar to the others,
1249 except that a name parameter is added. For programmers' that don't use
1250 ODR they probably only need to change the call to z_APDU and z_External.
1252 Added access control facility by interfacing the TCP wrapper library.
1253 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1254 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1255 name of the daemon and enables the access control as specified in
1256 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1258 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1259 den Dool <H.M.vdnDool@kub.nl>.
1261 Added reference ID parameter to most functions in server API - refer
1262 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1264 Changed name of ccl library to libccl.a (was ccl.a).
1266 Fixed bug in decoder for Explain (Category TargetInfo).
1268 Added support for GNU readline in client. Thanks to Jacob Poulsen
1269 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1271 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1272 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1273 IMPLEMENTATION! This change was made to the development version before
1274 the ZIG decided to retract the amendment. If any users MUST be
1275 compatible with the original Update definition, PLEASE CONTACT US, and
1276 we will include a separate definition corresponding to the old Update
1277 ES. Note that because of the change to the ASN.1 of the
1278 TaskPackageRecordStructure we cannot define a single structure that
1279 will support both versions.
1281 * Added const modifier to buffer parameter for some ODR/BER encoding
1282 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1283 completeWAIS, odr_dumpBER.
1285 Fixed bug in client.c which caused a crash when a scanResponse didn't
1286 contain positionOfTerm.
1288 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1289 * will cause an error in a client if a non-YAZ target sends both a
1290 * list of Scan entries and non-surrogate diagnostics.
1292 Retrieval module enhancements. Tag sets may be typed in the reference
1293 to it. From the .abs-file the "tagset" directive takes a third optional
1294 integer type for the tag set referenced. From a .tag-file the "include"
1295 directive takes a third optional type as well. The old "type" directive
1296 in the tag set itself is still recognized but acts as the default type
1299 Backend interface change. Individual Scan terms returned from bend_scan
1300 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1301 in include/backend.h.
1303 Retrieval module enhancements. Multiple tag sets and attribute sets may
1304 be specified in abstract syntax specs. Revised the error/warning for
1305 logging messages reported by the retrieval module when reading the
1308 Object Identifier system (oid_..) changed. The API is backwards
1309 compatible but the oid-routines now allocates new OID's when needed.
1310 Raw OID's may be specified in oid_getvalbyname.
1312 YAZ now uses GNU configure to generate Makefile(s).
1314 * Minor changes in some of the member names of DeleteResultSetRequest and
1315 DeleteResultSetResponse. See include/proto.h.
1317 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1318 and added member 'languages' in TargetInfo (which was missing).
1320 Changed the way attribute sets are handled in the retrieval
1321 module. These are now cached, just like the abstract syntaxes
1324 Changed YAZ so that it links with compiled ASN.1.
1326 Added Explain-schema definitions and mapping routines. The following
1327 Explain categories have been implemented: AttributeDetails,
1328 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1330 Fixed minor bug in Windows version of Server Library.
1332 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1334 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1336 Added EXTERNAL: UNIverse Resource Report (non-standard).
1338 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1339 ENUMERATED and SET OF.
1341 * Added 'const' to some of the char pointer arguments for the
1342 functions, data1_read_node, data1_getelementbytagname,
1343 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1346 Fixed bug in data1_insert_taggeddata - the last_child member of
1347 parent wasn't initialised.
1349 * Changed data1_read_record and data1_read_node so that the supplied
1350 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1351 doesn't refer to any parts of the "SGML"-buffer.
1353 Fixed bug in server library (Windows version of statserv_remove).
1355 * Changed code so that it compiles as C++. The type definition
1356 of Odr_fun which is a member of Odr_arm was changed. The result is,
1357 that an explicit typecast is needed for the fun pointer when
1358 using Odr_arm - as in:
1359 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1361 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1363 Implemented the new structured date and time definition as approved
1364 by the ZIG. Added schemaId element to the specificTag in Espec-1
1365 (also approved at the last ZIG). Thanks to RVDM.
1367 Added some Object identifiers (RVDM).
1369 Changed the Update Extended Service (RVDM).
1371 Added command "refid" to client which specifies referenceId for
1372 the following requests.
1374 Implemented extended service handling for server. See ztest.c
1375 for an example as well as backend.h. New handlers are registerd
1376 in the Init handler.
1378 * Changed interface for sort in server.
1380 Added new members to statserv_options_block. It allows a server
1381 to read options from another source than just the command line. Thanks
1382 to Charles Woodfield.
1384 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1385 renamed to zboolean. Some C++ compilers complained about the name.
1387 Minor changes to gils.abs. Added index 's' (sort) on title
1388 and date/time-last-modified.
1390 --- 1.4pl2 1998/1/30
1392 Fixed bug in server library regarding inetd mode (-i). This bug
1393 was introduced by release 1.4.
1395 --- 1.4pl1 1998/1/29
1397 Added sort facility in client and backend server interface.
1399 Fixed problem with dependencies in Makefile(s).
1401 Fixed bugs for encoders/decoders of extended services and
1404 Implemented sub-tree feature for schemas. Sub-trees are
1405 referenced in *.abs-files. See explain.abs for an example
1406 of the use of this feature.
1408 Modified bib1.att; local attributes for ANY didn't include
1409 ANY itself (only affects use of the retrieval module).
1411 Fixed bug in plain SGML reader in function data1_read_node:
1412 tags with prefix "var" was incorrectly interpreted as variants.
1414 Added feature "sub-schemas" to enable references to - and definitions
1415 of - group of elements.
1417 * Removed member parent from type data1_element (in data1.h).
1419 Implemented function odr_nullval() that returns the value of
1422 * Removed member num_children from data1_node (in data1.h).
1424 Made NT service interface part of the server library. The
1425 function statserv_main uses the NT service when required and
1426 calls the statserv_start / statserv_close routines.
1428 Routine zget_SearchRequest and zget_PresentRequest fills
1429 resultSetName/Id member with "default" instead of "Default".
1431 Fixed memory leak in server. Request queue member wasn't freed.
1433 Fixed nmem_exit so that memory is freed.
1437 Revised the CCL parser utility to be thread safe.
1439 Added function, oid_ent_to_oid, to replace the function
1440 oid_getoidbyent, which is not thread safe.
1442 * Added nmem_init and nmem_exit to initialize and release
1443 NMEM resources. Function nmem_init should be called once in the
1444 initial thread before NMEM/ODR is used. statserv.c and client.c
1445 have been changed accordingly. The change was necessary to make
1446 NMEM thread safe. The NMEM memory pool is shared amongst threads
1447 in a process. Unix-based applications will still work fine without
1450 Added NT Services interface for the the Z39.50 (statserv) Server.
1451 Refer to the ztest.c source on the usage.
1453 Windows 95/NT port using MSVC5.0. Project files are included in the
1456 * Defined new 'global' handle for the retrieval (data1) system. The
1457 new handled, data1_handle, describes the state of the data1 system.
1458 This handle is passed as first argument to virtually all
1459 data1 related routines. The functions data1_create and data1_destroy
1460 creates and destroys a data1 handle respectively.
1462 Added ODR encode stream member to all backend request structures
1463 init, search, scan etc. This stream should be used to allocate all
1464 memory used for the response when thread safe operation is needed.
1466 Changed the comstack utility, cs_addstr, to be thread safe. The
1467 returned hostname string returned by the function is now part the
1470 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1471 function. The cs_straddr takes a COMSTACK handle as argument, so this
1472 function must be used after cs_create and before bind/connect.
1473 This function is thread safe.
1475 Moved test server to 'ztest' directory - generic server code still
1476 in 'server' directory.
1478 Made prefix query (pquery.c) utility thread safe.
1480 Added new function modifier YAZ_EXPORT to 'export' public DLL
1481 functions when using windows (see include/yconfig.h).
1483 Added definitions to the OID database (util/oid.c) (RVDM).
1485 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1487 Added call to ccl_rpn_delete in client program.
1489 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1490 release of RPN structure.
1492 Added support for C++, headers uses extern "C" for public definitions.
1493 With input from RVDM.
1495 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1496 Thanks to Ronald van der Meer (RVDM).
1498 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1500 Added support for private extensions to the OID database
1501 (oid_setprivateoids()). Thanks to RVDM.
1503 Added optional, physical ANY (key replication)
1505 Fixed null-reference problem in GRS-1 output filter.
1507 Proximity operator added to Prefix Query Format (PQF).
1509 In test client command "base" accepts multiple databases.
1511 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1515 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1517 Smallish bug-fixes in the new encoders/decoders (explain).
1519 Bug fixed in DeleteRequest.
1521 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1523 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1525 Added SOIF syntax (using private OID for now) to retrieval module and client.
1527 Added Update extended service.
1529 Added SearchResult-1 additional info structure.
1531 Added optional CCL (ISO8777) interpreter as separate module. Available
1534 --- 1.2 1996/6/10 (1st anniversary release)
1536 Added Summary record syntax. Lightly tested.
1538 Added OPAC record syntax. Untested.
1540 Added ResourceReport service encoders/decoders. Untested.
1542 Fixed bug in z_Unit - wrong tagging on unitSystem.
1544 Fixed bug in the DiagRecs decoder.
1546 Added options for max PDU size and session timeout to frontend-server.
1548 Added documentation of query-language parsers and other supporting utilities.
1550 [frontend-server] Added Attribute set to the bend_scanrequest API.
1552 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1553 surrogate diagnostics were generated.
1555 [retrieval] Allow multiple local values for attribute.
1557 [retrieval] Allow multiple attributes per element in .abs files. index type.
1559 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1561 --- 1.1pl2 1996/4/10
1563 Minor changes, mostly specific to Zebra's requirements (retrieval)
1567 Repaired bug in frontend server when running multiple listening
1568 endpoints in dynamic mode.
1570 z_External() now won't break if a known, ASN.1 value comes encapsulated
1571 in an octet-string. The value will pass through unmodified in an Odr_oct.
1573 Added a bit of code to the demo client to decode & display
1574 ASN.1-structured records represented in the octet-aligned branch of
1575 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1577 Added z_ext_getentbyref() to the ASN module. Doc updated.
1579 * Completed the SCAN definition in the ASN module. This may break SCAN
1580 code based on older YAZ-versions at compile-time. The fix is easy -
1583 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1584 under the SCAN definition. Remember to initialize this, server-people.
1586 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1587 that this does not extend to ODR and ASN.
1589 Comstack allows insertion of established socket (primarily for
1590 inetd-operation of servers). Doc updated.
1592 Front-end server can now start from the inetd in TCP mode. Doc
1595 --- 1.0pl4 1996/1/24
1599 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1600 the rank and record number.
1602 Adjustments to the frontend server.
1604 Fixed diagnostic BER dumper. It ignored the file argument.
1608 Various changes to retrieval module.
1610 Changed the union discriminators of the protocol files from enums to
1611 ints paired with #defines.
1613 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1616 *Changed operator in the RPN structure to 'roperator', again to avoid a
1619 Fixed problems in Explain decoders/encoders.
1621 --- 1.0pl2 1995/12/6
1623 Memory bug in log module fixed.
1625 --- 1.0pl1 1995/12/5
1627 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1629 Bug in Explain DatabaseInfo module fixed.
1631 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1635 The shift to v1.0 signals that we now consider the *core* functionality
1636 of YAZ reasonably stable (the core being more or less equivalent to
1637 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1638 tested (Explain not at all - though that will happen soonish).
1640 Minor changes to code to support Windows port.
1642 Various minor changes after we're getting to use GRS-1 & co. more.
1644 Added Espec-1 format.
1646 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1647 of the protocol and it cannot be selected when encoding (maps into 'string'
1648 when decoding). Needed to talk to some servers.
1650 Demo client can request simple element set names.
1652 Added Diagnostic Format encoders/decoders.
1654 Added simple Close handling to frontend server (no hooks for resource
1655 reporting yet), and demonstration client.
1657 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1659 --- 1.0b3 1995/08/24
1661 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1662 handled incorrectly when records were requested in the searchResponse. This
1663 will only affect you if you use the frontend-server.
1665 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1666 Test-client will ask for and print GRS1. Ztest will return dummy records
1669 Added Explain encoders/decoders to the service-level API. Untested.
1671 Added Extended Services: Item Order encoders and decoders to the Service-
1672 level API. Untested. We could use a recent copy of the pertinent bits
1673 of the ILL protocol to add those bits.
1675 Added diagnostic format 1 encoders/decoders to the service-level API.
1678 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1679 odr_cons.c, which causes a more correct output.
1681 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1682 was always set to 0 when no records were requested in the searchRequest.
1684 * Added better external-handling. This shouldn't harm old code that
1685 *encodes* externals. It can break code that looks for a
1686 'single-ASN1-type' representation, since those types that are known
1687 are now decoded immediately. Look at the SUTRS sample code in
1688 seshigh.c and client.c. Documentation updated.
1690 Handling of structured records in bend_fetchresponse. Length -1 marks
1691 structured record, type is deduced from format field.
1693 --- 1.0b2 1995/06/27
1694 Fairly quick maintenance release to add SUTRS support.
1696 Fixed handling of SUTRS records in the demonstration client.
1698 * Added format field to the bend_fetchrequest and bend_fetchresponce
1699 structures of the backend API (frontend server). When the record is
1700 returned, the value of the format field is mapped to an OID. The
1701 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1702 of the record. The special value VAL_NONE in the bend_request means
1703 that no specific format was requested by the client. Documentation
1704 updated accordingly. Test server (ztest) will return a fixed dummy
1705 SUTRS record if your client requests SUTRS.
1707 Documentation updated accordingly.
1709 You can now set external libraries and RANLIB support in the top-level
1713 First public release.
