1 Possible compatibility problems with earlier versions marked with '*'.
3 CQL module modified to be case insensitive for relations/indexes/operations.
5 Fixed bug in CQL transform code: incorrect value relationModifieder
8 Added 'show all' command for yaz-client which retrieves all results
11 Added new yaz-client, xmles, which takes a (private) OID and
12 a document to be sent as an extended service request.
14 Describe new yaz-client commands wait_response and set_auto_wait.
16 Increase TCP/IP listener backlog from 3 (which I am guessing was
17 copied from the SunOS manual entry way back when) so SOMAXCONN, so
18 that the socket will queue as many incoming connections as it's able
19 to handle ongoing connections. In other words, it will never now
20 refuse a connection that it would be able to handle merely because
21 it's not got around to accepting() enough of the pending connections
22 yet. This is the behaviour anyway under Linux, where the listen()
23 argument is ignored; but not under BSD and on systems such as
24 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
25 YAZ-based servers should now be uniform across operating systems in
28 yaz-marcdump uses 64-bit file access on some systems. This is enabled
29 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
30 This allows yaz-marcdump to read large MARC batches (>2 GB).
32 Modified all YAZ source files - except the source which is auto-generated
33 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
38 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
39 MARC output rather than returning "new" buffer.
41 yaz-client warns about unknown init options.
43 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
47 Added support for SRW sort in Generic Frontend Server. Patch
48 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
49 sortKeys - or NULL if none is provided.
51 Fixed bug #307: It was impossible to specify indefinite/no timeout
52 for ZOOM_event. Special timeout value -1 now means indefinite timeout
55 Added support for multiple languages and charsets to be specified in
56 ZOOM. Each charset/language is separated by a blank. If negotiation is
57 in effect in init-response, Option
58 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
59 Code based on patch by Vasiliy Osadchuk.
61 Fixed bug #306: infinite recursion that occurred when calling
62 yaz_log_level_init as the first call (before other log level or
65 Fixed bug in scan handling in front end server: if preferred-Position-In-
66 Response was non-present, a NULL pointer referece was performed.
70 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
71 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
72 now defined for all those error codes. So instead of putting 109 in
73 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
74 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
76 Modified the yaz-marcdump utility to skip garbage bytes between MARC
79 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
81 Program yaz-client now exits and produces an error message if multiple
82 Z39.50 servers are specified on the command line (none or one allowed
85 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
90 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
92 Fixed bug #272: Preserve spacing for CCL terms.
96 Added support for virtual hosts and multiple backend servers for
97 the YAZ frontend server. The configution is XML based and
98 support specificition of CQL to RPN mappings and explain information.
99 See section "Virtual Hosts" in the YAZ manual.
101 Extended OPAC display utility. OPAC display utility renders
102 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
103 to supplement yaz_marc_decode_wrbuf.
105 Fixed a bug in MARC decoder that could caused it to crash for some
106 invalid MARC records. More diagnostics and warnings where added in
107 XML output (warnings, etc are stored in comments).
109 --- 2.0.34 2005/02/08
111 Fixes for UNIX domain sockets. Bug #261.
113 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
115 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
116 Added yaz_marc_subfield_str which defines subfield lead string which is
117 used in YAZ_MARC_LINE format. Default string is blank+$. Added
118 yaz_marc_endline_str which defines end of fields string used in
119 YAZ_MARC_LINE format. Default string is newline.
121 Experimental support for MarcXChange. This format can be produced
122 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
123 http://www.bs.dk/standards/MarcXchange.xsd
125 Added yaz-client commands scansize that sets maximum number of
126 entries to be returned by scan.
128 --- 2.0.32 2005/01/11
130 Added support for SRW scan in yaz-client and Generic Frontend Server.
132 * Added whereInList member to SRW Scan Term.
134 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
136 Fixed NMEM system to return aligned blocks on the smallest boundaries
137 that are suitably aligned for all possible types on the particular
138 architecture YAZ is being built for.
140 --- 2.0.30 2005/01/04
142 Fixed numerious warnings that was issued with newer versions of GCC.
144 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
145 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
148 Make YAZ Generic Frontend Server slightly faster.
150 Enhance (and reduce) logging for Generic Frontend Server.
152 Revert YAZ log system so that it flushes every write operation
153 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
155 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
156 instead of LOG_, due to name clash with syslog(3). LOG_ are still
157 present. New applications should define YAZ_USE_NEW_LOG=1 - this
158 will effectively disable old definitions.
160 --- 2.0.28 2004/11/09
162 Added yaz_log_time_format which specifies log format using
165 Added yaz_log_module_level which returns mask for a module. Value
166 is non-zero mask a if module is enabled; zero if disabled.
168 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
169 in include/yaz/cql.h.
171 Fixed bug #176: Dont throw diagnostics on empty SRU args.
173 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
175 Fixed bug #172: RPM builds does not enable SSL.
177 Doxyfile.in part of dist. Doxyfile generated by configure.
179 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
180 are given and the corresponding component does not exist.
182 Extend CCL documentation in YAZ reference. Describe r=r.
184 --- 2.0.26 2004/10/01
186 Fixed MARC->MARCXML conversion to properly deal with
187 fields, subfields, indicators having non-ASCII characters.
189 Fixed MARC->MARCXML conversion so that ASCII control characters
190 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
193 Added YAZ GFS support for conversion from Z39.50 surrogate
194 diagnostics to SRW surrogate diagnostics.
196 Bug fix: YAZ GFS did not return schema in explainResponse.
198 --- 2.0.25 2004/09/30
200 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
201 now converts recordSchema to elementSetName as well as schema URI.
203 Fixed bug in COMSTACK that prevented HTTP request packages from being
206 --- 2.0.24 2004/09/29
208 Added CCL facility r=r "range" which is similar to r=o "ordered" but
209 does not require white-space before and after the dash in a range, e.g.
210 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
213 Fixed a few AC_TRY_LINK configure tests that did not operate properly
214 due to new GCC removing "redundant" code.
216 Added yaz-client commands scanpos and scanstep that sets preferred
217 position and step-size for scan.
219 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
221 Added CCL utility ccl_qual_buf which parses one or more CCL
222 spec lines in a buffer.
224 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
225 of name and value - ignoring empty lines and comments.
227 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
229 Added odr_get_element_path which returns current element path for an
230 ODR handle. This utility is useful in error handling or user-defined
233 Added ODR_PRINT utility odr_set_stream which is is a more generic
234 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
235 to a write function and pointer to close function. The close function - if
236 non-NULL - will be called during odr_destroy.
238 Fixed bug in CCL parser where truncation char was not removed from
239 right side when truncation=both was in effect.
241 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
244 --- 2.0.23 2004/08/11
246 Fix buffer overrun in CQL parser when dealing with proximity (%).
248 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
249 to UTF-8/UCS conversion is now only based on codetables.xml.
251 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
253 --- 2.0.22 2004/08/06
255 Add support for more "commit changes" in ZOOM (uses Extended Services).
257 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
260 Yet another small fix for configure of SSL.
262 --- 2.0.21 2004/05/14
264 Fix SSL libs for configure when --with-openssl=DIR is given.
266 --- 2.0.20 2004/05/10
268 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
270 SSL comstack now uses yaz.pem certificate file on server side
271 by default. Certificate filename can be configured by calling
272 comstack function cs_set_ssl_certificate_file before cs_bind is used.
274 Fix bug regarding multiple calls to ZOOM_connection_connect.
276 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
278 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
279 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
281 ZOOM now allows inspection of X509 peer certificate for verification.
282 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
284 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
285 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
286 as "modular" but it simplifies things.
288 Added cs_get_peer_certificate to that returns peer X509 PEM.
290 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
291 NULL if SSL is unavailable.
293 Documentation about MARC decoding tools.
295 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
297 --- 2.0.19 2004/03/30
299 Rename CHANGELOG to NEWS to follow GNU style packing.
301 Fix bug with missing initialization of member in init_diagnostics.
302 This bug affects threaded version of GFS server.
304 --- 2.0.18 2004/03/20
306 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
309 Ensure zlib.dll is packed with Windows install.
311 --- 2.0.17 2004/03/17
313 Fix encoding of xsd:string to use text instead of CDATA.
315 Fix endless loop in CQL parser with unbalanced ".
317 Use a more compact way to store MARC-8 conversion tables.
319 --- 2.0.16 2004/03/16 Debian only
321 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
324 Update CQL parser to use new CQL 1.1 modifiers for booleans and
329 --- 2.0.15 2004/03/01
331 Another fix for decoding of XML packed records.
333 --- 2.0.14 2004/02/25
335 Fixes for Chunked encoding. White space not ignored after length spec.
337 Update NS and use default NS for SRW diagnostic elements.
339 --- 2.0.13 2004/02/23
341 Implement ZOOM_resultset_cache_reset which resets record cache.
343 Implement ZOOM_resultset_sort which sorts a result set.
345 Implement chunked HTTP transfer.
347 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
349 --- 2.0.12 2004/02/16
351 Added member 'schema' to bend_explain_rr structure so that backend
352 can specify explain record identifier. Defaults to Zeerex 2.0.
354 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
356 --- 2.0.11 2004/02/16
358 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
361 Added init command for yaz-client which sends "extra" init request.
363 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
364 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
366 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
368 Make ZOOM error code for "invalid query".
370 Fixed compilation for SSL which wasn't properly enabled for all platforms.
372 --- 2.0.10 2004/02/05
374 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
377 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
379 Added option -p <file> to make Generic Frontend Server to write PID file.
381 Added option -D to put Generic Frontend Server in background on its own.
383 Make ZOOM C recognize option "password". If unset, "pass" is used
384 (for backwards compatibility).
386 Fixed a bug in Generic Frontend Server that could make it crash if a
387 client sets characterSetNegotation bit, but didn't pass negotiation stuff
390 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
391 Must be issued before open, in order to be in effect.
393 --- 2.0.9-6 2004/01/12 Debian/Windows
395 Make the SRU server more picky WRT unknown params, etc.
397 Bug fix: ZOOM scan response didn't return displayTerm - when present.
399 New YAZ client command, options, that sets Z39.50 options.
401 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
402 options from a string of tokens (one token for each option bit).
404 Update SRW diagnostic code messages.
406 --- 2.0.9-5 2004/01/07 Debian/Windows
408 Handle user defined stylesheet for SRW/SRU.
410 --- 2.0.9-4 2004/01/06 Debian/Windows
412 Fix bug in decoding of Content-Length.
414 --- 2.0.9-3 2004/01/06 Debian/Windows
416 Fix a bug with decoding of XML packed records.
418 --- 2.0.9-2 2004/01/05 Debian only
420 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
422 Fix bug in SRW/SRU diagnostics decoding.
426 Fixed bug in Generic Frontend Server which could drop records exceeding
427 preferred message size. Reported and fixed by Irina Dijour.
429 Fixed calculation of package size for structured records in Generic
430 Frontend Server. Reported and fixed by Irina Dijour.
432 Fixed namespace for SRW/SRU diagnostics.
434 Fixed SEGV in yaz-client that occured for HTTP connection errors.
438 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
439 this version is incompatible with version 1.0 and older YAZ SRW/SRU
442 CQL changes to reflect recent changes to the specification:
443 * Documentation talks about context sets instead of index sets.
444 * Documentation talks about indexes instead of qualifiers.
445 * The CQL-to-PQF transformer's configuration file now uses
446 "index.set.name = <attributes>" instead of the old form
447 "qualifier.set.name = <attributes>". (Both forms are still
448 understood but the latter is deprecated.)
449 * CQL terms with no explicit index specified are now interpreted as
450 cql.serverChoice instead of srw.serverChoice (which of course
451 behaves exactly the same.)
455 MARC conversion can now generate ISO2709 output in another
456 character set. yaz-marcdump uses this facility if you invoke it
459 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
460 functions from there can be used from C++.
464 Frontend server now transfers memory from decoded packages to stream
467 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
468 references to show up.
470 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
471 the ZOOM Abstract API. The older names for the same options are still
472 also supported for the benefit of old applications.
474 ZOOM-C supports "implementationId" and "implementationVersion" options
475 to go along with "implementationName". These allow the user code to
476 specify identification strings to be sent to servers.
477 Add OID for the new ExtLite attribute set.
479 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
480 as requested/supplid by Ere Maijala <ere@atp.fi>
482 For generic frontend server, reverse the order of
483 "toolkit-supplied / application-supplied" strings sent as implementationId,
484 Name and Version. Also, remove the spaces around the slash. This brings
485 the GFS in line with the behaviour of ZOOM-C on the client side.
487 Add function ZOOM_scanset_display_term.
489 yaz-client shows scan displayTerm if present.
491 Utility yaz-iconv is now installed by default along with the man page
494 Extend configure check for OpenSSL to use pkg-config where available (such
497 Incorporate patch by Morten Bogeskov which allows a Unix file socket
498 server to specify uid/gid/mask for socket using the format
499 unix:[user=uid,][group=gid,][umask=mask,]file=path
500 If file= is omitted the existing format is assumed, e.g.
502 in which case the mask is 0666 (rw for everybody).
504 Major restructure of YAZ source. All source in libyaz is in src directory.
505 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
506 util (utility programs such as ASN.1 compiler, yaz-marcdump).
508 Added man page for utility yaz-marcdump (used to be called marcdump).
509 yaz-marcdump is installed by 'make install'.
511 Fixed a memory leak in Generic Frontend Server that occurred when decoding
512 of incoming package failed.
514 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
516 Change prototype of odr_perror: add const to message string.
518 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
520 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
521 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
522 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
523 DNS lookup. There should not be any compatibility problems with this
524 assuming that blocking=1 or 0 is used.
526 Fix bad reference in UNIX comstack in function cs_addrstr.
528 Fix for compilation on AIX.
530 The generic front-end server (server/seshigh.c) now supports returning
531 Init diagnostics to the client in User-information-field, in
532 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
537 Allow any CQL relation (not just all,any,exact,scr).
539 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
540 that features the same UI.
542 Implemented command update0 in YAZ client which is equivalent to
543 update but uses old of Ext Update ASN.1.
545 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
546 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
547 Previously no OID was used for this info.
549 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
550 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
551 returns 'malformed search term' otherwise.
553 SortResponse member resultCount now set to NULL in sort handler of
556 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
559 Add three new utility functions for translating OIDs between various
560 formats -- symbolic name such as "Usmarc", minus-1-terminated int
561 arrays and dotted strings such as "1.2.840.10003.9.5.1":
562 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
563 char *oid_to_dotstring(const int *oid, char *oidbuf);
564 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
566 Reverted modifications for ES Update definition for z_IU0Update
567 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
568 is back to YAZ 2.0.2.
570 String value attributes for CCL parser.
572 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
573 which their FirstSearch server returns in Init responses, sometimes
574 carrying useful diagnostic information when Init fails. This has the
575 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
576 "z39.50/oclcui.asn", where its definition is somewhat different from
577 what OCLC document on their web-site, as required to interoperate with
580 Support for anonymous authentication in yaz-client. Use the command
583 * Fix the OID of the Index Data-local "admin" Extended Service from
584 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
585 the 1000, which indicates a locally-defined OID, was a mistake.
589 Fix CCL directive @case handling so that it affects string match for
590 both CCL keywords and qualifiers.
592 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
593 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
594 Decoder has been updated with ASN.1 changes as listed in
595 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
596 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
597 z_IUUpdate, remains unchanged.
599 ZOOM_record_get may now return a record in a specific character set.
600 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
601 "from" is the character set of record as returned by target. "to" is
602 the character set to be returned. If omitted, "to" is UTF-8.
604 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
606 New ODR utility, odr_getelement, which returns name of element for
607 which encoding/decoding failed.
609 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
610 in cases where a required element was omitted.
612 Bug fix: some MARC8 sequences were not converted.
614 New ZOOM option "step" which specifies number of records to be
615 retrieved in one chunk. Used in conjunction with "start" and "count".
617 SRW support for yaz-client. Use scheme http: to use it, e.g.
620 yaz-client no longer does (un)intelligent character set conversions
621 by default. Can be enabled with charset and marc_charset commands.
623 xmalloc trace fix for 64-bit systems such as DEC alpha.
625 Solaris 2.6 compile fix.
627 New function, cql_strerror() translates SRW error codes, as returned
628 by cql_transform_error(), into human-readable English strings. Used
629 in yaz-client diagnostics when appropriate.
631 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
632 converts it into a type-1 query which is sent to the server. This
633 makes CQL available for use with all Z-servers, as opposed to the tiny
634 minority that can handle CQL queries themselves.
638 New Debian package layout similar to the Redhat Package layout.
640 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
641 and search result respectively.
645 Redhat package is now several packages: libyaz (runtime libraries),
646 libyaz-devel (development and documentation, and yaz (utility programs).
647 Package spec file by Morten Bøgeskov.
649 New member 'schema' in struct bend_fetch_rr which the name of requested
650 schema (SRW/SRU) for record (or NULL if none was given). The fetch
651 handler MAY set this to reflect the schema of the returned record.
653 New member 'display_term' in struct scan_entry. GFS now sets member entries
654 and allocates scan entries to be filled by user scan handler. In previous
655 version, entries member was allocated by the scan handler. That still works,
656 but the GFS will ignore member display_term - assuming it was NOT set by
657 the handler. The fact that the GFS now allocates the entries both allows
658 for new members and makes a scan handler easier to write.
660 Fix CQL lex buffer overflow.
662 SRW/SRU recordPacking. For SRW default recordPacking is string. For
663 SRU default recordPacking is string.
665 SRU protocol support for frontend server.
667 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
669 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
671 Added scan for the ZOOM shell (zoomsh).
675 * String Identifers for Schemas (Amendment 5).
676 http://lcweb.loc.gov/z3950/agency/amend/am5.html
677 Old definition for schema
678 Odr_oid *schema; /* OPT */
683 Z_InternationalString *uri;
684 #define Z_Schema_oid 1
685 #define Z_Schema_uri 2
688 * resultCount parameter to Sort Response (Amendment 1).
689 http://lcweb.loc.gov/z3950/agency/amend/am1.html
691 Support for SRW 1.0 over HTTP. This is an optional feature and
692 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
695 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
696 on the same port. SRW SearchRetrieveRequests are mapped
697 to bend_init,bend_search,bend_fetch,bend_close.
699 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
701 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
702 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
704 ZOOM connections are SRW based if schem http is used for hostname
705 in connect, e.g. z = ZOOM_connection_new("http://myserver");
706 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
708 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
709 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
710 distance=n, order=true/false, relation=le, prox unit=word. If
711 n is omitted, distance 1 is used.
713 Fixed problem with C compiler include path in wrong order.
715 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
716 on Solaris. Patch from Ko van der Sloot.
718 New MARC decode API. All new functions operate on a yaz_marc_t
719 handle. The most important new functions are: yaz_marc_create,
720 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
721 decode and destroy respectively. Decoder can produce formats
722 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
723 include/yaz/marcdisp.h.
725 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
726 to UTF-8, UCS-32, wchar_t or Latin-1.
728 * Prototypes for yaz_iconv_-functions moved to separate header
729 include/yaz/yaz-iconv.h.
731 Make a few private functions 'static' in unix.c. This prevents
732 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
734 For ZOOM connection, the options targetImplementation{Id,Name,Version}
735 are set when Init Response is received.
737 New function ZOOM_connection_error_x similar to ZOOM_connection_error
738 but returns diagnostic set as well.
740 New function yaz_strerror which is a portable wrapper for
741 strerror/strerror_r/GetLastMessage.
743 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
744 is returned for MARC. If type is "oai", then OAI MARC is returned.
746 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
751 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
753 Fix bad race conditions on SIGTERM and terminate gracefully in
756 Move retrieval (data1) module to Zebra since nobody seems to be
759 Add GRS-1 render for ZOOM using same format as yaz-client.
763 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
765 Fix broken ESpec handling in data1 module.
767 SGML reader parses comments and makes them part of the data1 tree.
769 Added several type casts so that YAZ compiles as C++ code.
771 ZOOM didn't handle PDU encoding failures properly.
773 Added more Bib-1 diagnostics (approved extensions).
775 GNU configure: better check for iconv.
777 More portable use of accept, getpeername. Check for socklen_t. Use
778 int/size_t if socklen_t is not defined.
782 PQF parser rejects bad queries - including those with extra
783 characters in them. PQF parser used to silently ignore that.
784 Cleaner API for PQF added, which allows you to get detailed
785 error information for bad queries (see yaz/pquery.h).
787 Fixed bug in ZOOM_record_get for type "database".
789 Implemented mini iconv library supporting conversions between
790 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
792 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
796 Fixed ZOOM C record cache so that preferredRecordSyntax and
797 elementSetName is used to check for already fetched records.
801 Added three members in bend_initrequest structure to facilitate
802 character set negotiation.
804 Fixed a bug in frontend server that could cause indefinite
805 loops under rare conditions.
807 Revised character set utilities (charneg.h) so that encoding
808 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
810 For PQF, directive @term <type> sets term type for Scan/Search.
811 Here <type> is general, string, numeric, null. The term type
812 is inherited - just like @attr.
814 New call odr_set_charset that sets character set conversion for
815 international-strings on a ODR stream. Prototype is:
816 int odr_set_charset(ODR o, const char *to, const char *from);
817 The InternationalString is still represented as C string in YAZ
818 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
819 won't). On the protocol level, you can use any encoding.
821 Support for UNIX sockets in ZOOM.
823 Solaris recv sometimes returns errno == ENOENT. It is treated as
824 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
826 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
827 both client and server. Code by Morten Bøgeskov.
831 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
832 that they can be used directly from Visual Basic. You must recompile
833 your windows APP if you're using ZOOM.
835 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
836 Commands "lang" and "charset" sets language and character set respectively.
837 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
838 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
840 Attributes from multiple CCL fields may be OR'ed rather than merged
841 using directive "@field or". Fields are still merged by default -
842 equivalent to "@field merge".
844 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
847 Fixed bug in zget for parameter ExtendedServicesResponse.
853 Added PQF feature: '@attr type=value' may be written as '@type=value'.
855 Client displays USR.1:SearchResult-1 (hits per term).
857 Additional Search Info for search in Generic Frontend Server.
859 Fixed CCL parsing of "field=s".
861 WIN32 installer - using the excellent NSIS software from nullsoft.
863 Fixed CCL parsing of "field = - <number>".
865 Added function yaz_marc_decode that decodes MARC for line mode
866 display or XML (similar to that used by JZKit).
868 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
869 Z39.50. But ISO/ILL was, however.
871 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
872 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
874 http://lcweb.loc.gov/z3950/agency/amend/am2.html
875 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
879 New YAZ client features: Command completion and new commands:
880 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
881 Code provided by Jacob Poulsen.
883 New call oid_trav, that visits all registered OIDs via callback.
885 Function ZOOM_record_get now returns const char pointer rather than
886 void pointer. It saves a lot of type casts.
888 For YAZ client, command "auth" now allows you to set authentication
889 in IdPass style. It is enabled when three tokens are given - order
890 is user, group and password.
892 Fix memory leaks in MARC record handling for ZOOM.
894 New option for YAZ client, -k <kilobytes> that sets
895 maximum record size. Similar to -k option for generic frontend
896 server and yaz-ztest.
898 More fixes for scan. Non-zero stepSize handled. OID's fixes.
900 Prefix query parser reports "fail" when bad attribute set is given.
902 Fix in MARC decoder. Proximity logging. Fix for attribute set
903 in scan handler for server. Patches by Shigeru Ishida.
905 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
908 Configure option --with-openssl=<dir> now works when a directory is
909 specified. Patch provided by Morten Bøgeskov.
911 New option for YAZ client, -u <auth>, that sets authentication.
913 ZOOM fix: error information was sometimes "missing", since error
914 was cleared/reset too when it shouldn't.
916 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
920 Scan for ZOOM API. New object ZOOM_scanset. New functions
921 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
922 ZOOM_scanset_destroy.
924 New ZOOM function, ZOOM_connection_last_event, that returns type
925 of last event (such as "receive data", "send data", "apdu received",
928 New ZOOM option, schema, that specifies schema for retrieval.
930 New CCL feature. Qualifiers can be aliases for one or more
931 other qualifiers (if more than one is given, OR is used).
933 ZOOM uses named result sets if target supports it.
935 Two new YAZ client commands: . (dot, which sources a script of YAZ
936 client commands), and ! (to execute shell command.). Implemented
939 Working on Debian packages.
943 YAZ client enables named result sets only if target supports it.
945 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
947 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
948 with key="host" to get same result.
950 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
951 Function Z3950_resultset_record(s) returns references to records
952 "owned" by resultset. To become owner use Z3950_record_clone.
954 Function z_ext_record handles Extended Services. Thanks to
959 CCL Parser fix: ignore token comma when dealing with and-lists.
961 Documentation updates for COMSTACK.
963 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
964 Changed prototype Z3950_records. For some functions, int parameters
965 were changed to size_t.
967 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
970 New MARC decode/display function, marc_display_exl, which properly rejects
971 non-ISO2709 records. YAZ client uses it.
975 Fix bug: local attribute set wasn't set correctly in PQF strings.
979 * Old Z39.50 codecs no longer supported.
981 Added ZOOM C binding. See http://zoom.z3950.org/
983 Renamed states for COMSTACKs to avoid confusion with events.
985 Implemented cs_look and proper cs_rcvconnect.
987 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
989 Configure detects POSIX threads on OpenBSD.
991 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
992 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
994 When error is returned from present handler, non-surrogate diagnostic
995 is returned in present response (and fetch handler is no longer called).
997 * Minor adjustments to pquery parser (PQF). Token characters may be
998 escaped by using backslash (C-style).
1000 PQF parser allows string attribute values to be specified. For @attr,
1001 non-numeric characters after the equal-sign are treated as strings
1002 (e.g. @attr 9=title).
1004 CCL trunction character may be defined (@truncation in file)
1006 * function zget_ExtendedServicesRequest sets waitAction to
1007 waitIfPossible (was wait).
1009 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1012 CCL operator names may be set in field definition files (CCL_bibset).
1013 See ccl/bib1 for an example.
1015 Fixes in ASN.1 compiler for C++ compatibility.
1017 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1018 and "op_or" to avoid conflict with C++.
1020 Fixed problem with GNU readline detection on Redhat 7.0.
1022 Added step-size for Scan backend handler.
1024 Fixed bug that made the frontend server crash when no attribute
1025 set was specified for scan.
1027 Front-end server automatically switches to original working directory
1028 when installed as an NT service. Previously -w had to be specified to
1031 Added extended attributes for retrieval module (data1), so that data1
1032 records carry d1_readXML/SGML attributes. d1_read also supports
1033 null-data rules ( <tag/>)
1035 On UNIX when POSIX threads are available, a separate library libyazthread
1036 is created. Programmers should link with that library and the yaz library
1037 when using threads. The reason for the split was that some applications
1038 on Linux, such as Apache, doesn't work well when using shared objects that
1041 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1042 (or any frontend server) in SSL mode by specifying ssl: followed by
1043 address. Only tested on UNIX.
1045 Added feature for CCL module. Virtual structure s=al or s=ol generates
1046 and-list and or-list respectively instead of phrase search.
1050 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1051 log_mask_str. This was done to avoid name conflicts with other libraries
1052 (such as other PHP extensions).
1054 Added raw OID member for preferred record syntax (request_format_raw)
1055 and returned record syntax (output_format_raw) for backend fetch method.
1057 Config file yaz-config now accepts options so that it returns specific
1058 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1060 Shared library support for UNIX using GNU libtool.
1062 * Modified backend interface. Request/Response struct's replaced by
1063 one read/write C struct. For example bend_fetchrequest and
1064 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1065 Every handler - even search has to be registered in bend_init
1066 handler. This means that the YAZ library no longer refers to
1067 external functions and it makes it possible to make the whole
1068 thing a single DLL/SO.
1070 Added Segment handler for backend server.
1072 Added Zmbol/Zebra administrative functions to YAZ client.
1074 Threaded frontend server on UNIX (when POSIX Threads are available).
1075 Starting the server with option -T enables multi-threading.
1079 Added configure option --enable-comp/disable-comp to control use
1080 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1081 located in sub directory asn.
1083 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1084 in ${exec_prefix}/bin along with the other programs yaz-client and
1087 GNU automake used to maintain makefiles.
1089 Added several OID's.
1091 Changed retrieval module so that we can load records with no abstract
1092 syntax defined. Tagpaths in these records are fully composed of string
1095 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1099 On UNIX, the generated makefile now supports a proper 'make install'.
1100 The prefix can be set via GNU configure to set the install location
1101 (default is /usr/local).
1103 * YAZ programs client and ztest were renamed to yaz-client and
1104 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1105 locations, such as /usr/bin,/usr/local/bin,etc.
1107 * YAZ Header files were moved from include to include/yaz. YAZ Header
1108 files are referred to as include <yaz/log.h> rather than <log.h>.
1109 The YAZ include path (-I ..) is therefore the same as before. Programmers
1110 should update their #include statements or use -Ipath/include/yaz
1111 instead. The main motivation for doing this change is that YAZ header files
1112 can be installed in "standard" locations /usr/include,/usr/local/include
1113 without introducing conflicts, since ALL YAZ header files are stored
1114 in subdirectory yaz (under /usr/include for example).
1116 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1117 rather than project/workspace files. We switched because project files
1118 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1121 Changed name of logging function, logf, to yaz_log, to prevent name
1122 clash with some math-log functions. The YAZ header log.h defines logf
1123 to yaz_log (#define) so there should be no incompatibilities by this
1126 Added bend_start/bend_stop handlers for server. These handler are
1127 called on start/stop of server. For windows they are called whenever
1128 a service is started/stopped.
1130 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1131 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1132 in util/yc.tcl. The auto-generated C code structures are, in a few
1133 cases, incompatible with the old decoders. There are differences in the
1134 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1135 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1136 The preprocessor variable ASN_COMPILED is defined when the compiled
1137 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1138 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1139 wish to use the old encoders/decoders you can specify --disable-yc
1142 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1143 version so that it supports both new - and old version of DB Update
1145 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1146 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1147 change. The name parameter can be set to 0 in which no name is specified
1148 for the construction. The macros odr_implicit and odr_explicit sets name
1149 parameter to zero for the construction involved. New macros
1150 odr_implicit_tag and odr_explicit_tag are similar to the others,
1151 except that a name parameter is added. For programmers' that don't use
1152 ODR they probably only need to change the call to z_APDU and z_External.
1154 Added access control facility by interfacing the TCP wrapper library.
1155 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1156 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1157 name of the daemon and enables the access control as specified in
1158 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1160 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1161 den Dool <H.M.vdnDool@kub.nl>.
1163 Added reference ID parameter to most functions in server API - refer
1164 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1166 Changed name of ccl library to libccl.a (was ccl.a).
1168 Fixed bug in decoder for Explain (Category TargetInfo).
1170 Added support for GNU readline in client. Thanks to Jacob Poulsen
1171 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1173 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1174 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1175 IMPLEMENTATION! This change was made to the development version before
1176 the ZIG decided to retract the amendment. If any users MUST be
1177 compatible with the original Update definition, PLEASE CONTACT US, and
1178 we will include a separate definition corresponding to the old Update
1179 ES. Note that because of the change to the ASN.1 of the
1180 TaskPackageRecordStructure we cannot define a single structure that
1181 will support both versions.
1183 * Added const modifier to buffer parameter for some ODR/BER encoding
1184 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1185 completeWAIS, odr_dumpBER.
1187 Fixed bug in client.c which caused a crash when a scanResponse didn't
1188 contain positionOfTerm.
1190 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1191 * will cause an error in a client if a non-YAZ target sends both a
1192 * list of Scan entries and non-surrogate diagnostics.
1194 Retrieval module enhancements. Tag sets may be typed in the reference
1195 to it. From the .abs-file the "tagset" directive takes a third optional
1196 integer type for the tag set referenced. From a .tag-file the "include"
1197 directive takes a third optional type as well. The old "type" directive
1198 in the tag set itself is still recognized but acts as the default type
1201 Backend interface change. Individual Scan terms returned from bend_scan
1202 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1203 in include/backend.h.
1205 Retrieval module enhancements. Multiple tag sets and attribute sets may
1206 be specified in abstract syntax specs. Revised the error/warning for
1207 logging messages reported by the retrieval module when reading the
1210 Object Identifier system (oid_..) changed. The API is backwards
1211 compatible but the oid-routines now allocates new OID's when needed.
1212 Raw OID's may be specified in oid_getvalbyname.
1214 YAZ now uses GNU configure to generate Makefile(s).
1216 * Minor changes in some of the member names of DeleteResultSetRequest and
1217 DeleteResultSetResponse. See include/proto.h.
1219 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1220 and added member 'languages' in TargetInfo (which was missing).
1222 Changed the way attribute sets are handled in the retrieval
1223 module. These are now cached, just like the abstract syntaxes
1226 Changed YAZ so that it links with compiled ASN.1.
1228 Added Explain-schema definitions and mapping routines. The following
1229 Explain categories have been implemented: AttributeDetails,
1230 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1232 Fixed minor bug in Windows version of Server Library.
1234 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1236 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1238 Added EXTERNAL: UNIverse Resource Report (non-standard).
1240 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1241 ENUMERATED and SET OF.
1243 * Added 'const' to some of the char pointer arguments for the
1244 functions, data1_read_node, data1_getelementbytagname,
1245 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1248 Fixed bug in data1_insert_taggeddata - the last_child member of
1249 parent wasn't initialised.
1251 * Changed data1_read_record and data1_read_node so that the supplied
1252 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1253 doesn't refer to any parts of the "SGML"-buffer.
1255 Fixed bug in server library (Windows version of statserv_remove).
1257 * Changed code so that it compiles as C++. The type definition
1258 of Odr_fun which is a member of Odr_arm was changed. The result is,
1259 that an explicit typecast is needed for the fun pointer when
1260 using Odr_arm - as in:
1261 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1263 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1265 Implemented the new structured date and time definition as approved
1266 by the ZIG. Added schemaId element to the specificTag in Espec-1
1267 (also approved at the last ZIG). Thanks to RVDM.
1269 Added some Object identifiers (RVDM).
1271 Changed the Update Extended Service (RVDM).
1273 Added command "refid" to client which specifies referenceId for
1274 the following requests.
1276 Implemented extended service handling for server. See ztest.c
1277 for an example as well as backend.h. New handlers are registerd
1278 in the Init handler.
1280 * Changed interface for sort in server.
1282 Added new members to statserv_options_block. It allows a server
1283 to read options from another source than just the command line. Thanks
1284 to Charles Woodfield.
1286 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1287 renamed to zboolean. Some C++ compilers complained about the name.
1289 Minor changes to gils.abs. Added index 's' (sort) on title
1290 and date/time-last-modified.
1292 --- 1.4pl2 1998/1/30
1294 Fixed bug in server library regarding inetd mode (-i). This bug
1295 was introduced by release 1.4.
1297 --- 1.4pl1 1998/1/29
1299 Added sort facility in client and backend server interface.
1301 Fixed problem with dependencies in Makefile(s).
1303 Fixed bugs for encoders/decoders of extended services and
1306 Implemented sub-tree feature for schemas. Sub-trees are
1307 referenced in *.abs-files. See explain.abs for an example
1308 of the use of this feature.
1310 Modified bib1.att; local attributes for ANY didn't include
1311 ANY itself (only affects use of the retrieval module).
1313 Fixed bug in plain SGML reader in function data1_read_node:
1314 tags with prefix "var" was incorrectly interpreted as variants.
1316 Added feature "sub-schemas" to enable references to - and definitions
1317 of - group of elements.
1319 * Removed member parent from type data1_element (in data1.h).
1321 Implemented function odr_nullval() that returns the value of
1324 * Removed member num_children from data1_node (in data1.h).
1326 Made NT service interface part of the server library. The
1327 function statserv_main uses the NT service when required and
1328 calls the statserv_start / statserv_close routines.
1330 Routine zget_SearchRequest and zget_PresentRequest fills
1331 resultSetName/Id member with "default" instead of "Default".
1333 Fixed memory leak in server. Request queue member wasn't freed.
1335 Fixed nmem_exit so that memory is freed.
1339 Revised the CCL parser utility to be thread safe.
1341 Added function, oid_ent_to_oid, to replace the function
1342 oid_getoidbyent, which is not thread safe.
1344 * Added nmem_init and nmem_exit to initialize and release
1345 NMEM resources. Function nmem_init should be called once in the
1346 initial thread before NMEM/ODR is used. statserv.c and client.c
1347 have been changed accordingly. The change was necessary to make
1348 NMEM thread safe. The NMEM memory pool is shared amongst threads
1349 in a process. Unix-based applications will still work fine without
1352 Added NT Services interface for the the Z39.50 (statserv) Server.
1353 Refer to the ztest.c source on the usage.
1355 Windows 95/NT port using MSVC5.0. Project files are included in the
1358 * Defined new 'global' handle for the retrieval (data1) system. The
1359 new handled, data1_handle, describes the state of the data1 system.
1360 This handle is passed as first argument to virtually all
1361 data1 related routines. The functions data1_create and data1_destroy
1362 creates and destroys a data1 handle respectively.
1364 Added ODR encode stream member to all backend request structures
1365 init, search, scan etc. This stream should be used to allocate all
1366 memory used for the response when thread safe operation is needed.
1368 Changed the comstack utility, cs_addstr, to be thread safe. The
1369 returned hostname string returned by the function is now part the
1372 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1373 function. The cs_straddr takes a COMSTACK handle as argument, so this
1374 function must be used after cs_create and before bind/connect.
1375 This function is thread safe.
1377 Moved test server to 'ztest' directory - generic server code still
1378 in 'server' directory.
1380 Made prefix query (pquery.c) utility thread safe.
1382 Added new function modifier YAZ_EXPORT to 'export' public DLL
1383 functions when using windows (see include/yconfig.h).
1385 Added definitions to the OID database (util/oid.c) (RVDM).
1387 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1389 Added call to ccl_rpn_delete in client program.
1391 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1392 release of RPN structure.
1394 Added support for C++, headers uses extern "C" for public definitions.
1395 With input from RVDM.
1397 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1398 Thanks to Ronald van der Meer (RVDM).
1400 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1402 Added support for private extensions to the OID database
1403 (oid_setprivateoids()). Thanks to RVDM.
1405 Added optional, physical ANY (key replication)
1407 Fixed null-reference problem in GRS-1 output filter.
1409 Proximity operator added to Prefix Query Format (PQF).
1411 In test client command "base" accepts multiple databases.
1413 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1417 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1419 Smallish bug-fixes in the new encoders/decoders (explain).
1421 Bug fixed in DeleteRequest.
1423 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1425 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1427 Added SOIF syntax (using private OID for now) to retrieval module and client.
1429 Added Update extended service.
1431 Added SearchResult-1 additional info structure.
1433 Added optional CCL (ISO8777) interpreter as separate module. Available
1436 --- 1.2 1996/6/10 (1st anniversary release)
1438 Added Summary record syntax. Lightly tested.
1440 Added OPAC record syntax. Untested.
1442 Added ResourceReport service encoders/decoders. Untested.
1444 Fixed bug in z_Unit - wrong tagging on unitSystem.
1446 Fixed bug in the DiagRecs decoder.
1448 Added options for max PDU size and session timeout to frontend-server.
1450 Added documentation of query-language parsers and other supporting utilities.
1452 [frontend-server] Added Attribute set to the bend_scanrequest API.
1454 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1455 surrogate diagnostics were generated.
1457 [retrieval] Allow multiple local values for attribute.
1459 [retrieval] Allow multiple attributes per element in .abs files. index type.
1461 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1463 --- 1.1pl2 1996/4/10
1465 Minor changes, mostly specific to Zebra's requirements (retrieval)
1469 Repaired bug in frontend server when running multiple listening
1470 endpoints in dynamic mode.
1472 z_External() now won't break if a known, ASN.1 value comes encapsulated
1473 in an octet-string. The value will pass through unmodified in an Odr_oct.
1475 Added a bit of code to the demo client to decode & display
1476 ASN.1-structured records represented in the octet-aligned branch of
1477 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1479 Added z_ext_getentbyref() to the ASN module. Doc updated.
1481 * Completed the SCAN definition in the ASN module. This may break SCAN
1482 code based on older YAZ-versions at compile-time. The fix is easy -
1485 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1486 under the SCAN definition. Remember to initialize this, server-people.
1488 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1489 that this does not extend to ODR and ASN.
1491 Comstack allows insertion of established socket (primarily for
1492 inetd-operation of servers). Doc updated.
1494 Front-end server can now start from the inetd in TCP mode. Doc
1497 --- 1.0pl4 1996/1/24
1501 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1502 the rank and record number.
1504 Adjustments to the frontend server.
1506 Fixed diagnostic BER dumper. It ignored the file argument.
1510 Various changes to retrieval module.
1512 Changed the union discriminators of the protocol files from enums to
1513 ints paired with #defines.
1515 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1518 *Changed operator in the RPN structure to 'roperator', again to avoid a
1521 Fixed problems in Explain decoders/encoders.
1523 --- 1.0pl2 1995/12/6
1525 Memory bug in log module fixed.
1527 --- 1.0pl1 1995/12/5
1529 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1531 Bug in Explain DatabaseInfo module fixed.
1533 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1537 The shift to v1.0 signals that we now consider the *core* functionality
1538 of YAZ reasonably stable (the core being more or less equivalent to
1539 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1540 tested (Explain not at all - though that will happen soonish).
1542 Minor changes to code to support Windows port.
1544 Various minor changes after we're getting to use GRS-1 & co. more.
1546 Added Espec-1 format.
1548 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1549 of the protocol and it cannot be selected when encoding (maps into 'string'
1550 when decoding). Needed to talk to some servers.
1552 Demo client can request simple element set names.
1554 Added Diagnostic Format encoders/decoders.
1556 Added simple Close handling to frontend server (no hooks for resource
1557 reporting yet), and demonstration client.
1559 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1561 --- 1.0b3 1995/08/24
1563 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1564 handled incorrectly when records were requested in the searchResponse. This
1565 will only affect you if you use the frontend-server.
1567 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1568 Test-client will ask for and print GRS1. Ztest will return dummy records
1571 Added Explain encoders/decoders to the service-level API. Untested.
1573 Added Extended Services: Item Order encoders and decoders to the Service-
1574 level API. Untested. We could use a recent copy of the pertinent bits
1575 of the ILL protocol to add those bits.
1577 Added diagnostic format 1 encoders/decoders to the service-level API.
1580 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1581 odr_cons.c, which causes a more correct output.
1583 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1584 was always set to 0 when no records were requested in the searchRequest.
1586 * Added better external-handling. This shouldn't harm old code that
1587 *encodes* externals. It can break code that looks for a
1588 'single-ASN1-type' representation, since those types that are known
1589 are now decoded immediately. Look at the SUTRS sample code in
1590 seshigh.c and client.c. Documentation updated.
1592 Handling of structured records in bend_fetchresponse. Length -1 marks
1593 structured record, type is deduced from format field.
1595 --- 1.0b2 1995/06/27
1596 Fairly quick maintenance release to add SUTRS support.
1598 Fixed handling of SUTRS records in the demonstration client.
1600 * Added format field to the bend_fetchrequest and bend_fetchresponce
1601 structures of the backend API (frontend server). When the record is
1602 returned, the value of the format field is mapped to an OID. The
1603 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1604 of the record. The special value VAL_NONE in the bend_request means
1605 that no specific format was requested by the client. Documentation
1606 updated accordingly. Test server (ztest) will return a fixed dummy
1607 SUTRS record if your client requests SUTRS.
1609 Documentation updated accordingly.
1611 You can now set external libraries and RANLIB support in the top-level
1615 First public release.
