1 Possible compatibility problems with earlier versions marked with '*'.
3 Added new yaz-client, xmles, which takes a (private) OID and
4 a document to be sent as an extended service request.
6 Describe new yaz-client commands wait_response and set_auto_wait.
8 Increase TCP/IP listener backlog from 3 (which I am guessing was
9 copied from the SunOS manual entry way back when) so SOMAXCONN, so
10 that the socket will queue as many incoming connections as it's able
11 to handle ongoing connections. In other words, it will never now
12 refuse a connection that it would be able to handle merely because
13 it's not got around to accepting() enough of the pending connections
14 yet. This is the behaviour anyway under Linux, where the listen()
15 argument is ignored; but not under BSD and on systems such as
16 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
17 YAZ-based servers should now be uniform across operating systems in
22 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
23 MARC output rather than returning "new" buffer.
25 yaz-client warns about unknown init options.
27 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
31 Added support for SRW sort in Generic Frontend Server. Patch
32 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
33 sortKeys - or NULL if none is provided.
35 Fixed bug #307: It was impossible to specify indefinite/no timeout
36 for ZOOM_event. Special timeout value -1 now means indefinite timeout
39 Added support for multiple languages and charsets to be specified in
40 ZOOM. Each charset/language is separated by a blank. If negotiation is
41 in effect in init-response, Option
42 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
43 Code based on patch by Vasiliy Osadchuk.
45 Fixed bug #306: infinite recursion that occurred when calling
46 yaz_log_level_init as the first call (before other log level or
49 Fixed bug in scan handling in front end server: if preferred-Position-In-
50 Response was non-present, a NULL pointer referece was performed.
54 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
55 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
56 now defined for all those error codes. So instead of putting 109 in
57 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
58 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
60 Modified the yaz-marcdump utility to skip garbage bytes between MARC
63 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
65 Program yaz-client now exits and produces an error message if multiple
66 Z39.50 servers are specified on the command line (none or one allowed
69 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
74 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
76 Fixed bug #272: Preserve spacing for CCL terms.
80 Added support for virtual hosts and multiple backend servers for
81 the YAZ frontend server. The configution is XML based and
82 support specificition of CQL to RPN mappings and explain information.
83 See section "Virtual Hosts" in the YAZ manual.
85 Extended OPAC display utility. OPAC display utility renders
86 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
87 to supplement yaz_marc_decode_wrbuf.
89 Fixed a bug in MARC decoder that could caused it to crash for some
90 invalid MARC records. More diagnostics and warnings where added in
91 XML output (warnings, etc are stored in comments).
95 Fixes for UNIX domain sockets. Bug #261.
97 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
99 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
100 Added yaz_marc_subfield_str which defines subfield lead string which is
101 used in YAZ_MARC_LINE format. Default string is blank+$. Added
102 yaz_marc_endline_str which defines end of fields string used in
103 YAZ_MARC_LINE format. Default string is newline.
105 Experimental support for MarcXChange. This format can be produced
106 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
107 http://www.bs.dk/standards/MarcXchange.xsd
109 Added yaz-client commands scansize that sets maximum number of
110 entries to be returned by scan.
112 --- 2.0.32 2005/01/11
114 Added support for SRW scan in yaz-client and Generic Frontend Server.
116 * Added whereInList member to SRW Scan Term.
118 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
120 Fixed NMEM system to return aligned blocks on the smallest boundaries
121 that are suitably aligned for all possible types on the particular
122 architecture YAZ is being built for.
124 --- 2.0.30 2005/01/04
126 Fixed numerious warnings that was issued with newer versions of GCC.
128 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
129 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
132 Make YAZ Generic Frontend Server slightly faster.
134 Enhance (and reduce) logging for Generic Frontend Server.
136 Revert YAZ log system so that it flushes every write operation
137 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
139 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
140 instead of LOG_, due to name clash with syslog(3). LOG_ are still
141 present. New applications should define YAZ_USE_NEW_LOG=1 - this
142 will effectively disable old definitions.
144 --- 2.0.28 2004/11/09
146 Added yaz_log_time_format which specifies log format using
149 Added yaz_log_module_level which returns mask for a module. Value
150 is non-zero mask a if module is enabled; zero if disabled.
152 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
153 in include/yaz/cql.h.
155 Fixed bug #176: Dont throw diagnostics on empty SRU args.
157 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
159 Fixed bug #172: RPM builds does not enable SSL.
161 Doxyfile.in part of dist. Doxyfile generated by configure.
163 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
164 are given and the corresponding component does not exist.
166 Extend CCL documentation in YAZ reference. Describe r=r.
168 --- 2.0.26 2004/10/01
170 Fixed MARC->MARCXML conversion to properly deal with
171 fields, subfields, indicators having non-ASCII characters.
173 Fixed MARC->MARCXML conversion so that ASCII control characters
174 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
177 Added YAZ GFS support for conversion from Z39.50 surrogate
178 diagnostics to SRW surrogate diagnostics.
180 Bug fix: YAZ GFS did not return schema in explainResponse.
182 --- 2.0.25 2004/09/30
184 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
185 now converts recordSchema to elementSetName as well as schema URI.
187 Fixed bug in COMSTACK that prevented HTTP request packages from being
190 --- 2.0.24 2004/09/29
192 Added CCL facility r=r "range" which is similar to r=o "ordered" but
193 does not require white-space before and after the dash in a range, e.g.
194 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
197 Fixed a few AC_TRY_LINK configure tests that did not operate properly
198 due to new GCC removing "redundant" code.
200 Added yaz-client commands scanpos and scanstep that sets preferred
201 position and step-size for scan.
203 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
205 Added CCL utility ccl_qual_buf which parses one or more CCL
206 spec lines in a buffer.
208 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
209 of name and value - ignoring empty lines and comments.
211 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
213 Added odr_get_element_path which returns current element path for an
214 ODR handle. This utility is useful in error handling or user-defined
217 Added ODR_PRINT utility odr_set_stream which is is a more generic
218 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
219 to a write function and pointer to close function. The close function - if
220 non-NULL - will be called during odr_destroy.
222 Fixed bug in CCL parser where truncation char was not removed from
223 right side when truncation=both was in effect.
225 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
228 --- 2.0.23 2004/08/11
230 Fix buffer overrun in CQL parser when dealing with proximity (%).
232 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
233 to UTF-8/UCS conversion is now only based on codetables.xml.
235 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
237 --- 2.0.22 2004/08/06
239 Add support for more "commit changes" in ZOOM (uses Extended Services).
241 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
244 Yet another small fix for configure of SSL.
246 --- 2.0.21 2004/05/14
248 Fix SSL libs for configure when --with-openssl=DIR is given.
250 --- 2.0.20 2004/05/10
252 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
254 SSL comstack now uses yaz.pem certificate file on server side
255 by default. Certificate filename can be configured by calling
256 comstack function cs_set_ssl_certificate_file before cs_bind is used.
258 Fix bug regarding multiple calls to ZOOM_connection_connect.
260 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
262 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
263 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
265 ZOOM now allows inspection of X509 peer certificate for verification.
266 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
268 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
269 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
270 as "modular" but it simplifies things.
272 Added cs_get_peer_certificate to that returns peer X509 PEM.
274 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
275 NULL if SSL is unavailable.
277 Documentation about MARC decoding tools.
279 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
281 --- 2.0.19 2004/03/30
283 Rename CHANGELOG to NEWS to follow GNU style packing.
285 Fix bug with missing initialization of member in init_diagnostics.
286 This bug affects threaded version of GFS server.
288 --- 2.0.18 2004/03/20
290 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
293 Ensure zlib.dll is packed with Windows install.
295 --- 2.0.17 2004/03/17
297 Fix encoding of xsd:string to use text instead of CDATA.
299 Fix endless loop in CQL parser with unbalanced ".
301 Use a more compact way to store MARC-8 conversion tables.
303 --- 2.0.16 2004/03/16 Debian only
305 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
308 Update CQL parser to use new CQL 1.1 modifiers for booleans and
313 --- 2.0.15 2004/03/01
315 Another fix for decoding of XML packed records.
317 --- 2.0.14 2004/02/25
319 Fixes for Chunked encoding. White space not ignored after length spec.
321 Update NS and use default NS for SRW diagnostic elements.
323 --- 2.0.13 2004/02/23
325 Implement ZOOM_resultset_cache_reset which resets record cache.
327 Implement ZOOM_resultset_sort which sorts a result set.
329 Implement chunked HTTP transfer.
331 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
333 --- 2.0.12 2004/02/16
335 Added member 'schema' to bend_explain_rr structure so that backend
336 can specify explain record identifier. Defaults to Zeerex 2.0.
338 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
340 --- 2.0.11 2004/02/16
342 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
345 Added init command for yaz-client which sends "extra" init request.
347 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
348 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
350 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
352 Make ZOOM error code for "invalid query".
354 Fixed compilation for SSL which wasn't properly enabled for all platforms.
356 --- 2.0.10 2004/02/05
358 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
361 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
363 Added option -p <file> to make Generic Frontend Server to write PID file.
365 Added option -D to put Generic Frontend Server in background on its own.
367 Make ZOOM C recognize option "password". If unset, "pass" is used
368 (for backwards compatibility).
370 Fixed a bug in Generic Frontend Server that could make it crash if a
371 client sets characterSetNegotation bit, but didn't pass negotiation stuff
374 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
375 Must be issued before open, in order to be in effect.
377 --- 2.0.9-6 2004/01/12 Debian/Windows
379 Make the SRU server more picky WRT unknown params, etc.
381 Bug fix: ZOOM scan response didn't return displayTerm - when present.
383 New YAZ client command, options, that sets Z39.50 options.
385 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
386 options from a string of tokens (one token for each option bit).
388 Update SRW diagnostic code messages.
390 --- 2.0.9-5 2004/01/07 Debian/Windows
392 Handle user defined stylesheet for SRW/SRU.
394 --- 2.0.9-4 2004/01/06 Debian/Windows
396 Fix bug in decoding of Content-Length.
398 --- 2.0.9-3 2004/01/06 Debian/Windows
400 Fix a bug with decoding of XML packed records.
402 --- 2.0.9-2 2004/01/05 Debian only
404 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
406 Fix bug in SRW/SRU diagnostics decoding.
410 Fixed bug in Generic Frontend Server which could drop records exceeding
411 preferred message size. Reported and fixed by Irina Dijour.
413 Fixed calculation of package size for structured records in Generic
414 Frontend Server. Reported and fixed by Irina Dijour.
416 Fixed namespace for SRW/SRU diagnostics.
418 Fixed SEGV in yaz-client that occured for HTTP connection errors.
422 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
423 this version is incompatible with version 1.0 and older YAZ SRW/SRU
426 CQL changes to reflect recent changes to the specification:
427 * Documentation talks about context sets instead of index sets.
428 * Documentation talks about indexes instead of qualifiers.
429 * The CQL-to-PQF transformer's configuration file now uses
430 "index.set.name = <attributes>" instead of the old form
431 "qualifier.set.name = <attributes>". (Both forms are still
432 understood but the latter is deprecated.)
433 * CQL terms with no explicit index specified are now interpreted as
434 cql.serverChoice instead of srw.serverChoice (which of course
435 behaves exactly the same.)
439 MARC conversion can now generate ISO2709 output in another
440 character set. yaz-marcdump uses this facility if you invoke it
443 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
444 functions from there can be used from C++.
448 Frontend server now transfers memory from decoded packages to stream
451 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
452 references to show up.
454 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
455 the ZOOM Abstract API. The older names for the same options are still
456 also supported for the benefit of old applications.
458 ZOOM-C supports "implementationId" and "implementationVersion" options
459 to go along with "implementationName". These allow the user code to
460 specify identification strings to be sent to servers.
461 Add OID for the new ExtLite attribute set.
463 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
464 as requested/supplid by Ere Maijala <ere@atp.fi>
466 For generic frontend server, reverse the order of
467 "toolkit-supplied / application-supplied" strings sent as implementationId,
468 Name and Version. Also, remove the spaces around the slash. This brings
469 the GFS in line with the behaviour of ZOOM-C on the client side.
471 Add function ZOOM_scanset_display_term.
473 yaz-client shows scan displayTerm if present.
475 Utility yaz-iconv is now installed by default along with the man page
478 Extend configure check for OpenSSL to use pkg-config where available (such
481 Incorporate patch by Morten Bogeskov which allows a Unix file socket
482 server to specify uid/gid/mask for socket using the format
483 unix:[user=uid,][group=gid,][umask=mask,]file=path
484 If file= is omitted the existing format is assumed, e.g.
486 in which case the mask is 0666 (rw for everybody).
488 Major restructure of YAZ source. All source in libyaz is in src directory.
489 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
490 util (utility programs such as ASN.1 compiler, yaz-marcdump).
492 Added man page for utility yaz-marcdump (used to be called marcdump).
493 yaz-marcdump is installed by 'make install'.
495 Fixed a memory leak in Generic Frontend Server that occurred when decoding
496 of incoming package failed.
498 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
500 Change prototype of odr_perror: add const to message string.
502 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
504 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
505 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
506 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
507 DNS lookup. There should not be any compatibility problems with this
508 assuming that blocking=1 or 0 is used.
510 Fix bad reference in UNIX comstack in function cs_addrstr.
512 Fix for compilation on AIX.
514 The generic front-end server (server/seshigh.c) now supports returning
515 Init diagnostics to the client in User-information-field, in
516 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
521 Allow any CQL relation (not just all,any,exact,scr).
523 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
524 that features the same UI.
526 Implemented command update0 in YAZ client which is equivalent to
527 update but uses old of Ext Update ASN.1.
529 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
530 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
531 Previously no OID was used for this info.
533 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
534 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
535 returns 'malformed search term' otherwise.
537 SortResponse member resultCount now set to NULL in sort handler of
540 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
543 Add three new utility functions for translating OIDs between various
544 formats -- symbolic name such as "Usmarc", minus-1-terminated int
545 arrays and dotted strings such as "1.2.840.10003.9.5.1":
546 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
547 char *oid_to_dotstring(const int *oid, char *oidbuf);
548 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
550 Reverted modifications for ES Update definition for z_IU0Update
551 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
552 is back to YAZ 2.0.2.
554 String value attributes for CCL parser.
556 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
557 which their FirstSearch server returns in Init responses, sometimes
558 carrying useful diagnostic information when Init fails. This has the
559 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
560 "z39.50/oclcui.asn", where its definition is somewhat different from
561 what OCLC document on their web-site, as required to interoperate with
564 Support for anonymous authentication in yaz-client. Use the command
567 * Fix the OID of the Index Data-local "admin" Extended Service from
568 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
569 the 1000, which indicates a locally-defined OID, was a mistake.
573 Fix CCL directive @case handling so that it affects string match for
574 both CCL keywords and qualifiers.
576 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
577 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
578 Decoder has been updated with ASN.1 changes as listed in
579 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
580 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
581 z_IUUpdate, remains unchanged.
583 ZOOM_record_get may now return a record in a specific character set.
584 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
585 "from" is the character set of record as returned by target. "to" is
586 the character set to be returned. If omitted, "to" is UTF-8.
588 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
590 New ODR utility, odr_getelement, which returns name of element for
591 which encoding/decoding failed.
593 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
594 in cases where a required element was omitted.
596 Bug fix: some MARC8 sequences were not converted.
598 New ZOOM option "step" which specifies number of records to be
599 retrieved in one chunk. Used in conjunction with "start" and "count".
601 SRW support for yaz-client. Use scheme http: to use it, e.g.
604 yaz-client no longer does (un)intelligent character set conversions
605 by default. Can be enabled with charset and marc_charset commands.
607 xmalloc trace fix for 64-bit systems such as DEC alpha.
609 Solaris 2.6 compile fix.
611 New function, cql_strerror() translates SRW error codes, as returned
612 by cql_transform_error(), into human-readable English strings. Used
613 in yaz-client diagnostics when appropriate.
615 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
616 converts it into a type-1 query which is sent to the server. This
617 makes CQL available for use with all Z-servers, as opposed to the tiny
618 minority that can handle CQL queries themselves.
622 New Debian package layout similar to the Redhat Package layout.
624 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
625 and search result respectively.
629 Redhat package is now several packages: libyaz (runtime libraries),
630 libyaz-devel (development and documentation, and yaz (utility programs).
631 Package spec file by Morten Bøgeskov.
633 New member 'schema' in struct bend_fetch_rr which the name of requested
634 schema (SRW/SRU) for record (or NULL if none was given). The fetch
635 handler MAY set this to reflect the schema of the returned record.
637 New member 'display_term' in struct scan_entry. GFS now sets member entries
638 and allocates scan entries to be filled by user scan handler. In previous
639 version, entries member was allocated by the scan handler. That still works,
640 but the GFS will ignore member display_term - assuming it was NOT set by
641 the handler. The fact that the GFS now allocates the entries both allows
642 for new members and makes a scan handler easier to write.
644 Fix CQL lex buffer overflow.
646 SRW/SRU recordPacking. For SRW default recordPacking is string. For
647 SRU default recordPacking is string.
649 SRU protocol support for frontend server.
651 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
653 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
655 Added scan for the ZOOM shell (zoomsh).
659 * String Identifers for Schemas (Amendment 5).
660 http://lcweb.loc.gov/z3950/agency/amend/am5.html
661 Old definition for schema
662 Odr_oid *schema; /* OPT */
667 Z_InternationalString *uri;
668 #define Z_Schema_oid 1
669 #define Z_Schema_uri 2
672 * resultCount parameter to Sort Response (Amendment 1).
673 http://lcweb.loc.gov/z3950/agency/amend/am1.html
675 Support for SRW 1.0 over HTTP. This is an optional feature and
676 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
679 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
680 on the same port. SRW SearchRetrieveRequests are mapped
681 to bend_init,bend_search,bend_fetch,bend_close.
683 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
685 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
686 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
688 ZOOM connections are SRW based if schem http is used for hostname
689 in connect, e.g. z = ZOOM_connection_new("http://myserver");
690 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
692 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
693 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
694 distance=n, order=true/false, relation=le, prox unit=word. If
695 n is omitted, distance 1 is used.
697 Fixed problem with C compiler include path in wrong order.
699 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
700 on Solaris. Patch from Ko van der Sloot.
702 New MARC decode API. All new functions operate on a yaz_marc_t
703 handle. The most important new functions are: yaz_marc_create,
704 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
705 decode and destroy respectively. Decoder can produce formats
706 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
707 include/yaz/marcdisp.h.
709 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
710 to UTF-8, UCS-32, wchar_t or Latin-1.
712 * Prototypes for yaz_iconv_-functions moved to separate header
713 include/yaz/yaz-iconv.h.
715 Make a few private functions 'static' in unix.c. This prevents
716 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
718 For ZOOM connection, the options targetImplementation{Id,Name,Version}
719 are set when Init Response is received.
721 New function ZOOM_connection_error_x similar to ZOOM_connection_error
722 but returns diagnostic set as well.
724 New function yaz_strerror which is a portable wrapper for
725 strerror/strerror_r/GetLastMessage.
727 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
728 is returned for MARC. If type is "oai", then OAI MARC is returned.
730 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
735 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
737 Fix bad race conditions on SIGTERM and terminate gracefully in
740 Move retrieval (data1) module to Zebra since nobody seems to be
743 Add GRS-1 render for ZOOM using same format as yaz-client.
747 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
749 Fix broken ESpec handling in data1 module.
751 SGML reader parses comments and makes them part of the data1 tree.
753 Added several type casts so that YAZ compiles as C++ code.
755 ZOOM didn't handle PDU encoding failures properly.
757 Added more Bib-1 diagnostics (approved extensions).
759 GNU configure: better check for iconv.
761 More portable use of accept, getpeername. Check for socklen_t. Use
762 int/size_t if socklen_t is not defined.
766 PQF parser rejects bad queries - including those with extra
767 characters in them. PQF parser used to silently ignore that.
768 Cleaner API for PQF added, which allows you to get detailed
769 error information for bad queries (see yaz/pquery.h).
771 Fixed bug in ZOOM_record_get for type "database".
773 Implemented mini iconv library supporting conversions between
774 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
776 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
780 Fixed ZOOM C record cache so that preferredRecordSyntax and
781 elementSetName is used to check for already fetched records.
785 Added three members in bend_initrequest structure to facilitate
786 character set negotiation.
788 Fixed a bug in frontend server that could cause indefinite
789 loops under rare conditions.
791 Revised character set utilities (charneg.h) so that encoding
792 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
794 For PQF, directive @term <type> sets term type for Scan/Search.
795 Here <type> is general, string, numeric, null. The term type
796 is inherited - just like @attr.
798 New call odr_set_charset that sets character set conversion for
799 international-strings on a ODR stream. Prototype is:
800 int odr_set_charset(ODR o, const char *to, const char *from);
801 The InternationalString is still represented as C string in YAZ
802 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
803 won't). On the protocol level, you can use any encoding.
805 Support for UNIX sockets in ZOOM.
807 Solaris recv sometimes returns errno == ENOENT. It is treated as
808 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
810 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
811 both client and server. Code by Morten Bøgeskov.
815 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
816 that they can be used directly from Visual Basic. You must recompile
817 your windows APP if you're using ZOOM.
819 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
820 Commands "lang" and "charset" sets language and character set respectively.
821 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
822 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
824 Attributes from multiple CCL fields may be OR'ed rather than merged
825 using directive "@field or". Fields are still merged by default -
826 equivalent to "@field merge".
828 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
831 Fixed bug in zget for parameter ExtendedServicesResponse.
837 Added PQF feature: '@attr type=value' may be written as '@type=value'.
839 Client displays USR.1:SearchResult-1 (hits per term).
841 Additional Search Info for search in Generic Frontend Server.
843 Fixed CCL parsing of "field=s".
845 WIN32 installer - using the excellent NSIS software from nullsoft.
847 Fixed CCL parsing of "field = - <number>".
849 Added function yaz_marc_decode that decodes MARC for line mode
850 display or XML (similar to that used by JZKit).
852 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
853 Z39.50. But ISO/ILL was, however.
855 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
856 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
858 http://lcweb.loc.gov/z3950/agency/amend/am2.html
859 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
863 New YAZ client features: Command completion and new commands:
864 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
865 Code provided by Jacob Poulsen.
867 New call oid_trav, that visits all registered OIDs via callback.
869 Function ZOOM_record_get now returns const char pointer rather than
870 void pointer. It saves a lot of type casts.
872 For YAZ client, command "auth" now allows you to set authentication
873 in IdPass style. It is enabled when three tokens are given - order
874 is user, group and password.
876 Fix memory leaks in MARC record handling for ZOOM.
878 New option for YAZ client, -k <kilobytes> that sets
879 maximum record size. Similar to -k option for generic frontend
880 server and yaz-ztest.
882 More fixes for scan. Non-zero stepSize handled. OID's fixes.
884 Prefix query parser reports "fail" when bad attribute set is given.
886 Fix in MARC decoder. Proximity logging. Fix for attribute set
887 in scan handler for server. Patches by Shigeru Ishida.
889 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
892 Configure option --with-openssl=<dir> now works when a directory is
893 specified. Patch provided by Morten Bøgeskov.
895 New option for YAZ client, -u <auth>, that sets authentication.
897 ZOOM fix: error information was sometimes "missing", since error
898 was cleared/reset too when it shouldn't.
900 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
904 Scan for ZOOM API. New object ZOOM_scanset. New functions
905 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
906 ZOOM_scanset_destroy.
908 New ZOOM function, ZOOM_connection_last_event, that returns type
909 of last event (such as "receive data", "send data", "apdu received",
912 New ZOOM option, schema, that specifies schema for retrieval.
914 New CCL feature. Qualifiers can be aliases for one or more
915 other qualifiers (if more than one is given, OR is used).
917 ZOOM uses named result sets if target supports it.
919 Two new YAZ client commands: . (dot, which sources a script of YAZ
920 client commands), and ! (to execute shell command.). Implemented
923 Working on Debian packages.
927 YAZ client enables named result sets only if target supports it.
929 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
931 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
932 with key="host" to get same result.
934 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
935 Function Z3950_resultset_record(s) returns references to records
936 "owned" by resultset. To become owner use Z3950_record_clone.
938 Function z_ext_record handles Extended Services. Thanks to
943 CCL Parser fix: ignore token comma when dealing with and-lists.
945 Documentation updates for COMSTACK.
947 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
948 Changed prototype Z3950_records. For some functions, int parameters
949 were changed to size_t.
951 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
954 New MARC decode/display function, marc_display_exl, which properly rejects
955 non-ISO2709 records. YAZ client uses it.
959 Fix bug: local attribute set wasn't set correctly in PQF strings.
963 * Old Z39.50 codecs no longer supported.
965 Added ZOOM C binding. See http://zoom.z3950.org/
967 Renamed states for COMSTACKs to avoid confusion with events.
969 Implemented cs_look and proper cs_rcvconnect.
971 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
973 Configure detects POSIX threads on OpenBSD.
975 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
976 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
978 When error is returned from present handler, non-surrogate diagnostic
979 is returned in present response (and fetch handler is no longer called).
981 * Minor adjustments to pquery parser (PQF). Token characters may be
982 escaped by using backslash (C-style).
984 PQF parser allows string attribute values to be specified. For @attr,
985 non-numeric characters after the equal-sign are treated as strings
986 (e.g. @attr 9=title).
988 CCL trunction character may be defined (@truncation in file)
990 * function zget_ExtendedServicesRequest sets waitAction to
991 waitIfPossible (was wait).
993 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
996 CCL operator names may be set in field definition files (CCL_bibset).
997 See ccl/bib1 for an example.
999 Fixes in ASN.1 compiler for C++ compatibility.
1001 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1002 and "op_or" to avoid conflict with C++.
1004 Fixed problem with GNU readline detection on Redhat 7.0.
1006 Added step-size for Scan backend handler.
1008 Fixed bug that made the frontend server crash when no attribute
1009 set was specified for scan.
1011 Front-end server automatically switches to original working directory
1012 when installed as an NT service. Previously -w had to be specified to
1015 Added extended attributes for retrieval module (data1), so that data1
1016 records carry d1_readXML/SGML attributes. d1_read also supports
1017 null-data rules ( <tag/>)
1019 On UNIX when POSIX threads are available, a separate library libyazthread
1020 is created. Programmers should link with that library and the yaz library
1021 when using threads. The reason for the split was that some applications
1022 on Linux, such as Apache, doesn't work well when using shared objects that
1025 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1026 (or any frontend server) in SSL mode by specifying ssl: followed by
1027 address. Only tested on UNIX.
1029 Added feature for CCL module. Virtual structure s=al or s=ol generates
1030 and-list and or-list respectively instead of phrase search.
1034 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1035 log_mask_str. This was done to avoid name conflicts with other libraries
1036 (such as other PHP extensions).
1038 Added raw OID member for preferred record syntax (request_format_raw)
1039 and returned record syntax (output_format_raw) for backend fetch method.
1041 Config file yaz-config now accepts options so that it returns specific
1042 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1044 Shared library support for UNIX using GNU libtool.
1046 * Modified backend interface. Request/Response struct's replaced by
1047 one read/write C struct. For example bend_fetchrequest and
1048 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1049 Every handler - even search has to be registered in bend_init
1050 handler. This means that the YAZ library no longer refers to
1051 external functions and it makes it possible to make the whole
1052 thing a single DLL/SO.
1054 Added Segment handler for backend server.
1056 Added Zmbol/Zebra administrative functions to YAZ client.
1058 Threaded frontend server on UNIX (when POSIX Threads are available).
1059 Starting the server with option -T enables multi-threading.
1063 Added configure option --enable-comp/disable-comp to control use
1064 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1065 located in sub directory asn.
1067 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1068 in ${exec_prefix}/bin along with the other programs yaz-client and
1071 GNU automake used to maintain makefiles.
1073 Added several OID's.
1075 Changed retrieval module so that we can load records with no abstract
1076 syntax defined. Tagpaths in these records are fully composed of string
1079 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1083 On UNIX, the generated makefile now supports a proper 'make install'.
1084 The prefix can be set via GNU configure to set the install location
1085 (default is /usr/local).
1087 * YAZ programs client and ztest were renamed to yaz-client and
1088 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1089 locations, such as /usr/bin,/usr/local/bin,etc.
1091 * YAZ Header files were moved from include to include/yaz. YAZ Header
1092 files are referred to as include <yaz/log.h> rather than <log.h>.
1093 The YAZ include path (-I ..) is therefore the same as before. Programmers
1094 should update their #include statements or use -Ipath/include/yaz
1095 instead. The main motivation for doing this change is that YAZ header files
1096 can be installed in "standard" locations /usr/include,/usr/local/include
1097 without introducing conflicts, since ALL YAZ header files are stored
1098 in subdirectory yaz (under /usr/include for example).
1100 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1101 rather than project/workspace files. We switched because project files
1102 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1105 Changed name of logging function, logf, to yaz_log, to prevent name
1106 clash with some math-log functions. The YAZ header log.h defines logf
1107 to yaz_log (#define) so there should be no incompatibilities by this
1110 Added bend_start/bend_stop handlers for server. These handler are
1111 called on start/stop of server. For windows they are called whenever
1112 a service is started/stopped.
1114 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1115 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1116 in util/yc.tcl. The auto-generated C code structures are, in a few
1117 cases, incompatible with the old decoders. There are differences in the
1118 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1119 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1120 The preprocessor variable ASN_COMPILED is defined when the compiled
1121 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1122 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1123 wish to use the old encoders/decoders you can specify --disable-yc
1126 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1127 version so that it supports both new - and old version of DB Update
1129 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1130 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1131 change. The name parameter can be set to 0 in which no name is specified
1132 for the construction. The macros odr_implicit and odr_explicit sets name
1133 parameter to zero for the construction involved. New macros
1134 odr_implicit_tag and odr_explicit_tag are similar to the others,
1135 except that a name parameter is added. For programmers' that don't use
1136 ODR they probably only need to change the call to z_APDU and z_External.
1138 Added access control facility by interfacing the TCP wrapper library.
1139 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1140 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1141 name of the daemon and enables the access control as specified in
1142 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1144 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1145 den Dool <H.M.vdnDool@kub.nl>.
1147 Added reference ID parameter to most functions in server API - refer
1148 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1150 Changed name of ccl library to libccl.a (was ccl.a).
1152 Fixed bug in decoder for Explain (Category TargetInfo).
1154 Added support for GNU readline in client. Thanks to Jacob Poulsen
1155 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1157 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1158 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1159 IMPLEMENTATION! This change was made to the development version before
1160 the ZIG decided to retract the amendment. If any users MUST be
1161 compatible with the original Update definition, PLEASE CONTACT US, and
1162 we will include a separate definition corresponding to the old Update
1163 ES. Note that because of the change to the ASN.1 of the
1164 TaskPackageRecordStructure we cannot define a single structure that
1165 will support both versions.
1167 * Added const modifier to buffer parameter for some ODR/BER encoding
1168 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1169 completeWAIS, odr_dumpBER.
1171 Fixed bug in client.c which caused a crash when a scanResponse didn't
1172 contain positionOfTerm.
1174 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1175 * will cause an error in a client if a non-YAZ target sends both a
1176 * list of Scan entries and non-surrogate diagnostics.
1178 Retrieval module enhancements. Tag sets may be typed in the reference
1179 to it. From the .abs-file the "tagset" directive takes a third optional
1180 integer type for the tag set referenced. From a .tag-file the "include"
1181 directive takes a third optional type as well. The old "type" directive
1182 in the tag set itself is still recognized but acts as the default type
1185 Backend interface change. Individual Scan terms returned from bend_scan
1186 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1187 in include/backend.h.
1189 Retrieval module enhancements. Multiple tag sets and attribute sets may
1190 be specified in abstract syntax specs. Revised the error/warning for
1191 logging messages reported by the retrieval module when reading the
1194 Object Identifier system (oid_..) changed. The API is backwards
1195 compatible but the oid-routines now allocates new OID's when needed.
1196 Raw OID's may be specified in oid_getvalbyname.
1198 YAZ now uses GNU configure to generate Makefile(s).
1200 * Minor changes in some of the member names of DeleteResultSetRequest and
1201 DeleteResultSetResponse. See include/proto.h.
1203 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1204 and added member 'languages' in TargetInfo (which was missing).
1206 Changed the way attribute sets are handled in the retrieval
1207 module. These are now cached, just like the abstract syntaxes
1210 Changed YAZ so that it links with compiled ASN.1.
1212 Added Explain-schema definitions and mapping routines. The following
1213 Explain categories have been implemented: AttributeDetails,
1214 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1216 Fixed minor bug in Windows version of Server Library.
1218 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1220 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1222 Added EXTERNAL: UNIverse Resource Report (non-standard).
1224 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1225 ENUMERATED and SET OF.
1227 * Added 'const' to some of the char pointer arguments for the
1228 functions, data1_read_node, data1_getelementbytagname,
1229 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1232 Fixed bug in data1_insert_taggeddata - the last_child member of
1233 parent wasn't initialised.
1235 * Changed data1_read_record and data1_read_node so that the supplied
1236 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1237 doesn't refer to any parts of the "SGML"-buffer.
1239 Fixed bug in server library (Windows version of statserv_remove).
1241 * Changed code so that it compiles as C++. The type definition
1242 of Odr_fun which is a member of Odr_arm was changed. The result is,
1243 that an explicit typecast is needed for the fun pointer when
1244 using Odr_arm - as in:
1245 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1247 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1249 Implemented the new structured date and time definition as approved
1250 by the ZIG. Added schemaId element to the specificTag in Espec-1
1251 (also approved at the last ZIG). Thanks to RVDM.
1253 Added some Object identifiers (RVDM).
1255 Changed the Update Extended Service (RVDM).
1257 Added command "refid" to client which specifies referenceId for
1258 the following requests.
1260 Implemented extended service handling for server. See ztest.c
1261 for an example as well as backend.h. New handlers are registerd
1262 in the Init handler.
1264 * Changed interface for sort in server.
1266 Added new members to statserv_options_block. It allows a server
1267 to read options from another source than just the command line. Thanks
1268 to Charles Woodfield.
1270 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1271 renamed to zboolean. Some C++ compilers complained about the name.
1273 Minor changes to gils.abs. Added index 's' (sort) on title
1274 and date/time-last-modified.
1276 --- 1.4pl2 1998/1/30
1278 Fixed bug in server library regarding inetd mode (-i). This bug
1279 was introduced by release 1.4.
1281 --- 1.4pl1 1998/1/29
1283 Added sort facility in client and backend server interface.
1285 Fixed problem with dependencies in Makefile(s).
1287 Fixed bugs for encoders/decoders of extended services and
1290 Implemented sub-tree feature for schemas. Sub-trees are
1291 referenced in *.abs-files. See explain.abs for an example
1292 of the use of this feature.
1294 Modified bib1.att; local attributes for ANY didn't include
1295 ANY itself (only affects use of the retrieval module).
1297 Fixed bug in plain SGML reader in function data1_read_node:
1298 tags with prefix "var" was incorrectly interpreted as variants.
1300 Added feature "sub-schemas" to enable references to - and definitions
1301 of - group of elements.
1303 * Removed member parent from type data1_element (in data1.h).
1305 Implemented function odr_nullval() that returns the value of
1308 * Removed member num_children from data1_node (in data1.h).
1310 Made NT service interface part of the server library. The
1311 function statserv_main uses the NT service when required and
1312 calls the statserv_start / statserv_close routines.
1314 Routine zget_SearchRequest and zget_PresentRequest fills
1315 resultSetName/Id member with "default" instead of "Default".
1317 Fixed memory leak in server. Request queue member wasn't freed.
1319 Fixed nmem_exit so that memory is freed.
1323 Revised the CCL parser utility to be thread safe.
1325 Added function, oid_ent_to_oid, to replace the function
1326 oid_getoidbyent, which is not thread safe.
1328 * Added nmem_init and nmem_exit to initialize and release
1329 NMEM resources. Function nmem_init should be called once in the
1330 initial thread before NMEM/ODR is used. statserv.c and client.c
1331 have been changed accordingly. The change was necessary to make
1332 NMEM thread safe. The NMEM memory pool is shared amongst threads
1333 in a process. Unix-based applications will still work fine without
1336 Added NT Services interface for the the Z39.50 (statserv) Server.
1337 Refer to the ztest.c source on the usage.
1339 Windows 95/NT port using MSVC5.0. Project files are included in the
1342 * Defined new 'global' handle for the retrieval (data1) system. The
1343 new handled, data1_handle, describes the state of the data1 system.
1344 This handle is passed as first argument to virtually all
1345 data1 related routines. The functions data1_create and data1_destroy
1346 creates and destroys a data1 handle respectively.
1348 Added ODR encode stream member to all backend request structures
1349 init, search, scan etc. This stream should be used to allocate all
1350 memory used for the response when thread safe operation is needed.
1352 Changed the comstack utility, cs_addstr, to be thread safe. The
1353 returned hostname string returned by the function is now part the
1356 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1357 function. The cs_straddr takes a COMSTACK handle as argument, so this
1358 function must be used after cs_create and before bind/connect.
1359 This function is thread safe.
1361 Moved test server to 'ztest' directory - generic server code still
1362 in 'server' directory.
1364 Made prefix query (pquery.c) utility thread safe.
1366 Added new function modifier YAZ_EXPORT to 'export' public DLL
1367 functions when using windows (see include/yconfig.h).
1369 Added definitions to the OID database (util/oid.c) (RVDM).
1371 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1373 Added call to ccl_rpn_delete in client program.
1375 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1376 release of RPN structure.
1378 Added support for C++, headers uses extern "C" for public definitions.
1379 With input from RVDM.
1381 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1382 Thanks to Ronald van der Meer (RVDM).
1384 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1386 Added support for private extensions to the OID database
1387 (oid_setprivateoids()). Thanks to RVDM.
1389 Added optional, physical ANY (key replication)
1391 Fixed null-reference problem in GRS-1 output filter.
1393 Proximity operator added to Prefix Query Format (PQF).
1395 In test client command "base" accepts multiple databases.
1397 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1401 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1403 Smallish bug-fixes in the new encoders/decoders (explain).
1405 Bug fixed in DeleteRequest.
1407 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1409 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1411 Added SOIF syntax (using private OID for now) to retrieval module and client.
1413 Added Update extended service.
1415 Added SearchResult-1 additional info structure.
1417 Added optional CCL (ISO8777) interpreter as separate module. Available
1420 --- 1.2 1996/6/10 (1st anniversary release)
1422 Added Summary record syntax. Lightly tested.
1424 Added OPAC record syntax. Untested.
1426 Added ResourceReport service encoders/decoders. Untested.
1428 Fixed bug in z_Unit - wrong tagging on unitSystem.
1430 Fixed bug in the DiagRecs decoder.
1432 Added options for max PDU size and session timeout to frontend-server.
1434 Added documentation of query-language parsers and other supporting utilities.
1436 [frontend-server] Added Attribute set to the bend_scanrequest API.
1438 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1439 surrogate diagnostics were generated.
1441 [retrieval] Allow multiple local values for attribute.
1443 [retrieval] Allow multiple attributes per element in .abs files. index type.
1445 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1447 --- 1.1pl2 1996/4/10
1449 Minor changes, mostly specific to Zebra's requirements (retrieval)
1453 Repaired bug in frontend server when running multiple listening
1454 endpoints in dynamic mode.
1456 z_External() now won't break if a known, ASN.1 value comes encapsulated
1457 in an octet-string. The value will pass through unmodified in an Odr_oct.
1459 Added a bit of code to the demo client to decode & display
1460 ASN.1-structured records represented in the octet-aligned branch of
1461 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1463 Added z_ext_getentbyref() to the ASN module. Doc updated.
1465 * Completed the SCAN definition in the ASN module. This may break SCAN
1466 code based on older YAZ-versions at compile-time. The fix is easy -
1469 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1470 under the SCAN definition. Remember to initialize this, server-people.
1472 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1473 that this does not extend to ODR and ASN.
1475 Comstack allows insertion of established socket (primarily for
1476 inetd-operation of servers). Doc updated.
1478 Front-end server can now start from the inetd in TCP mode. Doc
1481 --- 1.0pl4 1996/1/24
1485 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1486 the rank and record number.
1488 Adjustments to the frontend server.
1490 Fixed diagnostic BER dumper. It ignored the file argument.
1494 Various changes to retrieval module.
1496 Changed the union discriminators of the protocol files from enums to
1497 ints paired with #defines.
1499 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1502 *Changed operator in the RPN structure to 'roperator', again to avoid a
1505 Fixed problems in Explain decoders/encoders.
1507 --- 1.0pl2 1995/12/6
1509 Memory bug in log module fixed.
1511 --- 1.0pl1 1995/12/5
1513 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1515 Bug in Explain DatabaseInfo module fixed.
1517 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1521 The shift to v1.0 signals that we now consider the *core* functionality
1522 of YAZ reasonably stable (the core being more or less equivalent to
1523 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1524 tested (Explain not at all - though that will happen soonish).
1526 Minor changes to code to support Windows port.
1528 Various minor changes after we're getting to use GRS-1 & co. more.
1530 Added Espec-1 format.
1532 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1533 of the protocol and it cannot be selected when encoding (maps into 'string'
1534 when decoding). Needed to talk to some servers.
1536 Demo client can request simple element set names.
1538 Added Diagnostic Format encoders/decoders.
1540 Added simple Close handling to frontend server (no hooks for resource
1541 reporting yet), and demonstration client.
1543 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1545 --- 1.0b3 1995/08/24
1547 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1548 handled incorrectly when records were requested in the searchResponse. This
1549 will only affect you if you use the frontend-server.
1551 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1552 Test-client will ask for and print GRS1. Ztest will return dummy records
1555 Added Explain encoders/decoders to the service-level API. Untested.
1557 Added Extended Services: Item Order encoders and decoders to the Service-
1558 level API. Untested. We could use a recent copy of the pertinent bits
1559 of the ILL protocol to add those bits.
1561 Added diagnostic format 1 encoders/decoders to the service-level API.
1564 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1565 odr_cons.c, which causes a more correct output.
1567 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1568 was always set to 0 when no records were requested in the searchRequest.
1570 * Added better external-handling. This shouldn't harm old code that
1571 *encodes* externals. It can break code that looks for a
1572 'single-ASN1-type' representation, since those types that are known
1573 are now decoded immediately. Look at the SUTRS sample code in
1574 seshigh.c and client.c. Documentation updated.
1576 Handling of structured records in bend_fetchresponse. Length -1 marks
1577 structured record, type is deduced from format field.
1579 --- 1.0b2 1995/06/27
1580 Fairly quick maintenance release to add SUTRS support.
1582 Fixed handling of SUTRS records in the demonstration client.
1584 * Added format field to the bend_fetchrequest and bend_fetchresponce
1585 structures of the backend API (frontend server). When the record is
1586 returned, the value of the format field is mapped to an OID. The
1587 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1588 of the record. The special value VAL_NONE in the bend_request means
1589 that no specific format was requested by the client. Documentation
1590 updated accordingly. Test server (ztest) will return a fixed dummy
1591 SUTRS record if your client requests SUTRS.
1593 Documentation updated accordingly.
1595 You can now set external libraries and RANLIB support in the top-level
1599 First public release.
