1 Possible compatibility problems with earlier versions marked with '*'.
3 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
4 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
5 now defined for all those error codes. So instead of putting 109 in
6 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The
7 messages are now generated from a .csv - file. See src/bib1.csv and
10 Modified the yaz-marcdump utility to skip garbage bytes between MARC
13 Fixed bug - uinitialized memory - introduced by code introduced by
18 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
20 Fixed bug #272: Preserve spacing for CCL terms.
24 Added support for virtual hosts and multiple backend servers for
25 the YAZ frontend server. The configution is XML based and
26 support specificition of CQL to RPN mappings and explain information.
27 See section "Virtual Hosts" in the YAZ manual.
29 Extended OPAC display utility. OPAC display utility renders
30 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
31 to supplement yaz_marc_decode_wrbuf.
33 Fixed a bug in MARC decoder that could caused it to crash for some
34 invalid MARC records. More diagnostics and warnings where added in
35 XML output (warnings, etc are stored in comments).
39 Fixes for UNIX domain sockets. Bug #261.
41 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
43 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
44 Added yaz_marc_subfield_str which defines subfield lead string which is
45 used in YAZ_MARC_LINE format. Default string is blank+$. Added
46 yaz_marc_endline_str which defines end of fields string used in
47 YAZ_MARC_LINE format. Default string is newline.
49 Experimental support for MarcXChange. This format can be produced
50 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
51 http://www.bs.dk/standards/MarcXchange.xsd
53 Added yaz-client commands scansize that sets maximum number of
54 entries to be returned by scan.
58 Added support for SRW scan in yaz-client and Generic Frontend Server.
60 * Added whereInList member to SRW Scan Term.
62 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
64 Fixed NMEM system to return aligned blocks on the smallest boundaries
65 that are suitably aligned for all possible types on the particular
66 architecture YAZ is being built for.
70 Fixed numerious warnings that was issued with newer versions of GCC.
72 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
73 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
76 Make YAZ Generic Frontend Server slightly faster.
78 Enhance (and reduce) logging for Generic Frontend Server.
80 Revert YAZ log system so that it flushes every write operation
81 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
83 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
84 instead of LOG_, due to name clash with syslog(3). LOG_ are still
85 present. New applications should define YAZ_USE_NEW_LOG=1 - this
86 will effectively disable old definitions.
90 Added yaz_log_time_format which specifies log format using
93 Added yaz_log_module_level which returns mask for a module. Value
94 is non-zero mask a if module is enabled; zero if disabled.
96 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
99 Fixed bug #176: Dont throw diagnostics on empty SRU args.
101 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
103 Fixed bug #172: RPM builds does not enable SSL.
105 Doxyfile.in part of dist. Doxyfile generated by configure.
107 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
108 are given and the corresponding component does not exist.
110 Extend CCL documentation in YAZ reference. Describe r=r.
112 --- 2.0.26 2004/10/01
114 Fixed MARC->MARCXML conversion to properly deal with
115 fields, subfields, indicators having non-ASCII characters.
117 Fixed MARC->MARCXML conversion so that ASCII control characters
118 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
121 Added YAZ GFS support for conversion from Z39.50 surrogate
122 diagnostics to SRW surrogate diagnostics.
124 Bug fix: YAZ GFS did not return schema in explainResponse.
126 --- 2.0.25 2004/09/30
128 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
129 now converts recordSchema to elementSetName as well as schema URI.
131 Fixed bug in COMSTACK that prevented HTTP request packages from being
134 --- 2.0.24 2004/09/29
136 Added CCL facility r=r "range" which is similar to r=o "ordered" but
137 does not require white-space before and after the dash in a range, e.g.
138 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
141 Fixed a few AC_TRY_LINK configure tests that did not operate properly
142 due to new GCC removing "redundant" code.
144 Added yaz-client commands scanpos and scanstep that sets preferred
145 position and step-size for scan.
147 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
149 Added CCL utility ccl_qual_buf which parses one or more CCL
150 spec lines in a buffer.
152 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
153 of name and value - ignoring empty lines and comments.
155 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
157 Added odr_get_element_path which returns current element path for an
158 ODR handle. This utility is useful in error handling or user-defined
161 Added ODR_PRINT utility odr_set_stream which is is a more generic
162 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
163 to a write function and pointer to close function. The close function - if
164 non-NULL - will be called during odr_destroy.
166 Fixed bug in CCL parser where truncation char was not removed from
167 right side when truncation=both was in effect.
169 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
172 --- 2.0.23 2004/08/11
174 Fix buffer overrun in CQL parser when dealing with proximity (%).
176 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
177 to UTF-8/UCS conversion is now only based on codetables.xml.
179 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
181 --- 2.0.22 2004/08/06
183 Add support for more "commit changes" in ZOOM (uses Extended Services).
185 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
188 Yet another small fix for configure of SSL.
190 --- 2.0.21 2004/05/14
192 Fix SSL libs for configure when --with-openssl=DIR is given.
194 --- 2.0.20 2004/05/10
196 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
198 SSL comstack now uses yaz.pem certificate file on server side
199 by default. Certificate filename can be configured by calling
200 comstack function cs_set_ssl_certificate_file before cs_bind is used.
202 Fix bug regarding multiple calls to ZOOM_connection_connect.
204 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
206 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
207 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
209 ZOOM now allows inspection of X509 peer certificate for verification.
210 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
212 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
213 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
214 as "modular" but it simplifies things.
216 Added cs_get_peer_certificate to that returns peer X509 PEM.
218 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
219 NULL if SSL is unavailable.
221 Documentation about MARC decoding tools.
223 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
225 --- 2.0.19 2004/03/30
227 Rename CHANGELOG to NEWS to follow GNU style packing.
229 Fix bug with missing initialization of member in init_diagnostics.
230 This bug affects threaded version of GFS server.
232 --- 2.0.18 2004/03/20
234 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
237 Ensure zlib.dll is packed with Windows install.
239 --- 2.0.17 2004/03/17
241 Fix encoding of xsd:string to use text instead of CDATA.
243 Fix endless loop in CQL parser with unbalanced ".
245 Use a more compact way to store MARC-8 conversion tables.
247 --- 2.0.16 2004/03/16 Debian only
249 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
252 Update CQL parser to use new CQL 1.1 modifiers for booleans and
257 --- 2.0.15 2004/03/01
259 Another fix for decoding of XML packed records.
261 --- 2.0.14 2004/02/25
263 Fixes for Chunked encoding. White space not ignored after length spec.
265 Update NS and use default NS for SRW diagnostic elements.
267 --- 2.0.13 2004/02/23
269 Implement ZOOM_resultset_cache_reset which resets record cache.
271 Implement ZOOM_resultset_sort which sorts a result set.
273 Implement chunked HTTP transfer.
275 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
277 --- 2.0.12 2004/02/16
279 Added member 'schema' to bend_explain_rr structure so that backend
280 can specify explain record identifier. Defaults to Zeerex 2.0.
282 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
284 --- 2.0.11 2004/02/16
286 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
289 Added init command for yaz-client which sends "extra" init request.
291 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
292 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
294 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
296 Make ZOOM error code for "invalid query".
298 Fixed compilation for SSL which wasn't properly enabled for all platforms.
300 --- 2.0.10 2004/02/05
302 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
305 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
307 Added option -p <file> to make Generic Frontend Server to write PID file.
309 Added option -D to put Generic Frontend Server in background on its own.
311 Make ZOOM C recognize option "password". If unset, "pass" is used
312 (for backwards compatibility).
314 Fixed a bug in Generic Frontend Server that could make it crash if a
315 client sets characterSetNegotation bit, but didn't pass negotiation stuff
318 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
319 Must be issued before open, in order to be in effect.
321 --- 2.0.9-6 2004/01/12 Debian/Windows
323 Make the SRU server more picky WRT unknown params, etc.
325 Bug fix: ZOOM scan response didn't return displayTerm - when present.
327 New YAZ client command, options, that sets Z39.50 options.
329 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
330 options from a string of tokens (one token for each option bit).
332 Update SRW diagnostic code messages.
334 --- 2.0.9-5 2004/01/07 Debian/Windows
336 Handle user defined stylesheet for SRW/SRU.
338 --- 2.0.9-4 2004/01/06 Debian/Windows
340 Fix bug in decoding of Content-Length.
342 --- 2.0.9-3 2004/01/06 Debian/Windows
344 Fix a bug with decoding of XML packed records.
346 --- 2.0.9-2 2004/01/05 Debian only
348 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
350 Fix bug in SRW/SRU diagnostics decoding.
354 Fixed bug in Generic Frontend Server which could drop records exceeding
355 preferred message size. Reported and fixed by Irina Dijour.
357 Fixed calculation of package size for structured records in Generic
358 Frontend Server. Reported and fixed by Irina Dijour.
360 Fixed namespace for SRW/SRU diagnostics.
362 Fixed SEGV in yaz-client that occured for HTTP connection errors.
366 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
367 this version is incompatible with version 1.0 and older YAZ SRW/SRU
370 CQL changes to reflect recent changes to the specification:
371 * Documentation talks about context sets instead of index sets.
372 * Documentation talks about indexes instead of qualifiers.
373 * The CQL-to-PQF transformer's configuration file now uses
374 "index.set.name = <attributes>" instead of the old form
375 "qualifier.set.name = <attributes>". (Both forms are still
376 understood but the latter is deprecated.)
377 * CQL terms with no explicit index specified are now interpreted as
378 cql.serverChoice instead of srw.serverChoice (which of course
379 behaves exactly the same.)
383 MARC conversion can now generate ISO2709 output in another
384 character set. yaz-marcdump uses this facility if you invoke it
387 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
388 functions from there can be used from C++.
392 Frontend server now transfers memory from decoded packages to stream
395 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
396 references to show up.
398 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
399 the ZOOM Abstract API. The older names for the same options are still
400 also supported for the benefit of old applications.
402 ZOOM-C supports "implementationId" and "implementationVersion" options
403 to go along with "implementationName". These allow the user code to
404 specify identification strings to be sent to servers.
405 Add OID for the new ExtLite attribute set.
407 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
408 as requested/supplid by Ere Maijala <ere@atp.fi>
410 For generic frontend server, reverse the order of
411 "toolkit-supplied / application-supplied" strings sent as implementationId,
412 Name and Version. Also, remove the spaces around the slash. This brings
413 the GFS in line with the behaviour of ZOOM-C on the client side.
415 Add function ZOOM_scanset_display_term.
417 yaz-client shows scan displayTerm if present.
419 Utility yaz-iconv is now installed by default along with the man page
422 Extend configure check for OpenSSL to use pkg-config where available (such
425 Incorporate patch by Morten Bogeskov which allows a Unix file socket
426 server to specify uid/gid/mask for socket using the format
427 unix:[user=uid,][group=gid,][umask=mask,]file=path
428 If file= is omitted the existing format is assumed, e.g.
430 in which case the mask is 0666 (rw for everybody).
432 Major restructure of YAZ source. All source in libyaz is in src directory.
433 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
434 util (utility programs such as ASN.1 compiler, yaz-marcdump).
436 Added man page for utility yaz-marcdump (used to be called marcdump).
437 yaz-marcdump is installed by 'make install'.
439 Fixed a memory leak in Generic Frontend Server that occurred when decoding
440 of incoming package failed.
442 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
444 Change prototype of odr_perror: add const to message string.
446 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
448 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
449 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
450 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
451 DNS lookup. There should not be any compatibility problems with this
452 assuming that blocking=1 or 0 is used.
454 Fix bad reference in UNIX comstack in function cs_addrstr.
456 Fix for compilation on AIX.
458 The generic front-end server (server/seshigh.c) now supports returning
459 Init diagnostics to the client in User-information-field, in
460 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
465 Allow any CQL relation (not just all,any,exact,scr).
467 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
468 that features the same UI.
470 Implemented command update0 in YAZ client which is equivalent to
471 update but uses old of Ext Update ASN.1.
473 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
474 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
475 Previously no OID was used for this info.
477 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
478 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
479 returns 'malformed search term' otherwise.
481 SortResponse member resultCount now set to NULL in sort handler of
484 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
487 Add three new utility functions for translating OIDs between various
488 formats -- symbolic name such as "Usmarc", minus-1-terminated int
489 arrays and dotted strings such as "1.2.840.10003.9.5.1":
490 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
491 char *oid_to_dotstring(const int *oid, char *oidbuf);
492 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
494 Reverted modifications for ES Update definition for z_IU0Update
495 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
496 is back to YAZ 2.0.2.
498 String value attributes for CCL parser.
500 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
501 which their FirstSearch server returns in Init responses, sometimes
502 carrying useful diagnostic information when Init fails. This has the
503 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
504 "z39.50/oclcui.asn", where its definition is somewhat different from
505 what OCLC document on their web-site, as required to interoperate with
508 Support for anonymous authentication in yaz-client. Use the command
511 * Fix the OID of the Index Data-local "admin" Extended Service from
512 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
513 the 1000, which indicates a locally-defined OID, was a mistake.
517 Fix CCL directive @case handling so that it affects string match for
518 both CCL keywords and qualifiers.
520 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
521 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
522 Decoder has been updated with ASN.1 changes as listed in
523 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
524 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
525 z_IUUpdate, remains unchanged.
527 ZOOM_record_get may now return a record in a specific character set.
528 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
529 "from" is the character set of record as returned by target. "to" is
530 the character set to be returned. If omitted, "to" is UTF-8.
532 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
534 New ODR utility, odr_getelement, which returns name of element for
535 which encoding/decoding failed.
537 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
538 in cases where a required element was omitted.
540 Bug fix: some MARC8 sequences were not converted.
542 New ZOOM option "step" which specifies number of records to be
543 retrieved in one chunk. Used in conjunction with "start" and "count".
545 SRW support for yaz-client. Use scheme http: to use it, e.g.
548 yaz-client no longer does (un)intelligent character set conversions
549 by default. Can be enabled with charset and marc_charset commands.
551 xmalloc trace fix for 64-bit systems such as DEC alpha.
553 Solaris 2.6 compile fix.
555 New function, cql_strerror() translates SRW error codes, as returned
556 by cql_transform_error(), into human-readable English strings. Used
557 in yaz-client diagnostics when appropriate.
559 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
560 converts it into a type-1 query which is sent to the server. This
561 makes CQL available for use with all Z-servers, as opposed to the tiny
562 minority that can handle CQL queries themselves.
566 New Debian package layout similar to the Redhat Package layout.
568 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
569 and search result respectively.
573 Redhat package is now several packages: libyaz (runtime libraries),
574 libyaz-devel (development and documentation, and yaz (utility programs).
575 Package spec file by Morten Bøgeskov.
577 New member 'schema' in struct bend_fetch_rr which the name of requested
578 schema (SRW/SRU) for record (or NULL if none was given). The fetch
579 handler MAY set this to reflect the schema of the returned record.
581 New member 'display_term' in struct scan_entry. GFS now sets member entries
582 and allocates scan entries to be filled by user scan handler. In previous
583 version, entries member was allocated by the scan handler. That still works,
584 but the GFS will ignore member display_term - assuming it was NOT set by
585 the handler. The fact that the GFS now allocates the entries both allows
586 for new members and makes a scan handler easier to write.
588 Fix CQL lex buffer overflow.
590 SRW/SRU recordPacking. For SRW default recordPacking is string. For
591 SRU default recordPacking is string.
593 SRU protocol support for frontend server.
595 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
597 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
599 Added scan for the ZOOM shell (zoomsh).
603 * String Identifers for Schemas (Amendment 5).
604 http://lcweb.loc.gov/z3950/agency/amend/am5.html
605 Old definition for schema
606 Odr_oid *schema; /* OPT */
611 Z_InternationalString *uri;
612 #define Z_Schema_oid 1
613 #define Z_Schema_uri 2
616 * resultCount parameter to Sort Response (Amendment 1).
617 http://lcweb.loc.gov/z3950/agency/amend/am1.html
619 Support for SRW 1.0 over HTTP. This is an optional feature and
620 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
623 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
624 on the same port. SRW SearchRetrieveRequests are mapped
625 to bend_init,bend_search,bend_fetch,bend_close.
627 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
629 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
630 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
632 ZOOM connections are SRW based if schem http is used for hostname
633 in connect, e.g. z = ZOOM_connection_new("http://myserver");
634 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
636 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
637 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
638 distance=n, order=true/false, relation=le, prox unit=word. If
639 n is omitted, distance 1 is used.
641 Fixed problem with C compiler include path in wrong order.
643 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
644 on Solaris. Patch from Ko van der Sloot.
646 New MARC decode API. All new functions operate on a yaz_marc_t
647 handle. The most important new functions are: yaz_marc_create,
648 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
649 decode and destroy respectively. Decoder can produce formats
650 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
651 include/yaz/marcdisp.h.
653 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
654 to UTF-8, UCS-32, wchar_t or Latin-1.
656 * Prototypes for yaz_iconv_-functions moved to separate header
657 include/yaz/yaz-iconv.h.
659 Make a few private functions 'static' in unix.c. This prevents
660 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
662 For ZOOM connection, the options targetImplementation{Id,Name,Version}
663 are set when Init Response is received.
665 New function ZOOM_connection_error_x similar to ZOOM_connection_error
666 but returns diagnostic set as well.
668 New function yaz_strerror which is a portable wrapper for
669 strerror/strerror_r/GetLastMessage.
671 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
672 is returned for MARC. If type is "oai", then OAI MARC is returned.
674 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
679 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
681 Fix bad race conditions on SIGTERM and terminate gracefully in
684 Move retrieval (data1) module to Zebra since nobody seems to be
687 Add GRS-1 render for ZOOM using same format as yaz-client.
691 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
693 Fix broken ESpec handling in data1 module.
695 SGML reader parses comments and makes them part of the data1 tree.
697 Added several type casts so that YAZ compiles as C++ code.
699 ZOOM didn't handle PDU encoding failures properly.
701 Added more Bib-1 diagnostics (approved extensions).
703 GNU configure: better check for iconv.
705 More portable use of accept, getpeername. Check for socklen_t. Use
706 int/size_t if socklen_t is not defined.
710 PQF parser rejects bad queries - including those with extra
711 characters in them. PQF parser used to silently ignore that.
712 Cleaner API for PQF added, which allows you to get detailed
713 error information for bad queries (see yaz/pquery.h).
715 Fixed bug in ZOOM_record_get for type "database".
717 Implemented mini iconv library supporting conversions between
718 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
720 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
724 Fixed ZOOM C record cache so that preferredRecordSyntax and
725 elementSetName is used to check for already fetched records.
729 Added three members in bend_initrequest structure to facilitate
730 character set negotiation.
732 Fixed a bug in frontend server that could cause indefinite
733 loops under rare conditions.
735 Revised character set utilities (charneg.h) so that encoding
736 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
738 For PQF, directive @term <type> sets term type for Scan/Search.
739 Here <type> is general, string, numeric, null. The term type
740 is inherited - just like @attr.
742 New call odr_set_charset that sets character set conversion for
743 international-strings on a ODR stream. Prototype is:
744 int odr_set_charset(ODR o, const char *to, const char *from);
745 The InternationalString is still represented as C string in YAZ
746 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
747 won't). On the protocol level, you can use any encoding.
749 Support for UNIX sockets in ZOOM.
751 Solaris recv sometimes returns errno == ENOENT. It is treated as
752 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
754 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
755 both client and server. Code by Morten Bøgeskov.
759 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
760 that they can be used directly from Visual Basic. You must recompile
761 your windows APP if you're using ZOOM.
763 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
764 Commands "lang" and "charset" sets language and character set respectively.
765 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
766 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
768 Attributes from multiple CCL fields may be OR'ed rather than merged
769 using directive "@field or". Fields are still merged by default -
770 equivalent to "@field merge".
772 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
775 Fixed bug in zget for parameter ExtendedServicesResponse.
781 Added PQF feature: '@attr type=value' may be written as '@type=value'.
783 Client displays USR.1:SearchResult-1 (hits per term).
785 Additional Search Info for search in Generic Frontend Server.
787 Fixed CCL parsing of "field=s".
789 WIN32 installer - using the excellent NSIS software from nullsoft.
791 Fixed CCL parsing of "field = - <number>".
793 Added function yaz_marc_decode that decodes MARC for line mode
794 display or XML (similar to that used by JZKit).
796 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
797 Z39.50. But ISO/ILL was, however.
799 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
800 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
802 http://lcweb.loc.gov/z3950/agency/amend/am2.html
803 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
807 New YAZ client features: Command completion and new commands:
808 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
809 Code provided by Jacob Poulsen.
811 New call oid_trav, that visits all registered OIDs via callback.
813 Function ZOOM_record_get now returns const char pointer rather than
814 void pointer. It saves a lot of type casts.
816 For YAZ client, command "auth" now allows you to set authentication
817 in IdPass style. It is enabled when three tokens are given - order
818 is user, group and password.
820 Fix memory leaks in MARC record handling for ZOOM.
822 New option for YAZ client, -k <kilobytes> that sets
823 maximum record size. Similar to -k option for generic frontend
824 server and yaz-ztest.
826 More fixes for scan. Non-zero stepSize handled. OID's fixes.
828 Prefix query parser reports "fail" when bad attribute set is given.
830 Fix in MARC decoder. Proximity logging. Fix for attribute set
831 in scan handler for server. Patches by Shigeru Ishida.
833 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
836 Configure option --with-openssl=<dir> now works when a directory is
837 specified. Patch provided by Morten Bøgeskov.
839 New option for YAZ client, -u <auth>, that sets authentication.
841 ZOOM fix: error information was sometimes "missing", since error
842 was cleared/reset too when it shouldn't.
844 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
848 Scan for ZOOM API. New object ZOOM_scanset. New functions
849 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
850 ZOOM_scanset_destroy.
852 New ZOOM function, ZOOM_connection_last_event, that returns type
853 of last event (such as "receive data", "send data", "apdu received",
856 New ZOOM option, schema, that specifies schema for retrieval.
858 New CCL feature. Qualifiers can be aliases for one or more
859 other qualifiers (if more than one is given, OR is used).
861 ZOOM uses named result sets if target supports it.
863 Two new YAZ client commands: . (dot, which sources a script of YAZ
864 client commands), and ! (to execute shell command.). Implemented
867 Working on Debian packages.
871 YAZ client enables named result sets only if target supports it.
873 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
875 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
876 with key="host" to get same result.
878 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
879 Function Z3950_resultset_record(s) returns references to records
880 "owned" by resultset. To become owner use Z3950_record_clone.
882 Function z_ext_record handles Extended Services. Thanks to
887 CCL Parser fix: ignore token comma when dealing with and-lists.
889 Documentation updates for COMSTACK.
891 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
892 Changed prototype Z3950_records. For some functions, int parameters
893 were changed to size_t.
895 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
898 New MARC decode/display function, marc_display_exl, which properly rejects
899 non-ISO2709 records. YAZ client uses it.
903 Fix bug: local attribute set wasn't set correctly in PQF strings.
907 * Old Z39.50 codecs no longer supported.
909 Added ZOOM C binding. See http://zoom.z3950.org/
911 Renamed states for COMSTACKs to avoid confusion with events.
913 Implemented cs_look and proper cs_rcvconnect.
915 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
917 Configure detects POSIX threads on OpenBSD.
919 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
920 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
922 When error is returned from present handler, non-surrogate diagnostic
923 is returned in present response (and fetch handler is no longer called).
925 * Minor adjustments to pquery parser (PQF). Token characters may be
926 escaped by using backslash (C-style).
928 PQF parser allows string attribute values to be specified. For @attr,
929 non-numeric characters after the equal-sign are treated as strings
930 (e.g. @attr 9=title).
932 CCL trunction character may be defined (@truncation in file)
934 * function zget_ExtendedServicesRequest sets waitAction to
935 waitIfPossible (was wait).
937 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
940 CCL operator names may be set in field definition files (CCL_bibset).
941 See ccl/bib1 for an example.
943 Fixes in ASN.1 compiler for C++ compatibility.
945 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
946 and "op_or" to avoid conflict with C++.
948 Fixed problem with GNU readline detection on Redhat 7.0.
950 Added step-size for Scan backend handler.
952 Fixed bug that made the frontend server crash when no attribute
953 set was specified for scan.
955 Front-end server automatically switches to original working directory
956 when installed as an NT service. Previously -w had to be specified to
959 Added extended attributes for retrieval module (data1), so that data1
960 records carry d1_readXML/SGML attributes. d1_read also supports
961 null-data rules ( <tag/>)
963 On UNIX when POSIX threads are available, a separate library libyazthread
964 is created. Programmers should link with that library and the yaz library
965 when using threads. The reason for the split was that some applications
966 on Linux, such as Apache, doesn't work well when using shared objects that
969 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
970 (or any frontend server) in SSL mode by specifying ssl: followed by
971 address. Only tested on UNIX.
973 Added feature for CCL module. Virtual structure s=al or s=ol generates
974 and-list and or-list respectively instead of phrase search.
978 * Added prefix "yaz_" for the functions log_init.., log_file.. and
979 log_mask_str. This was done to avoid name conflicts with other libraries
980 (such as other PHP extensions).
982 Added raw OID member for preferred record syntax (request_format_raw)
983 and returned record syntax (output_format_raw) for backend fetch method.
985 Config file yaz-config now accepts options so that it returns specific
986 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
988 Shared library support for UNIX using GNU libtool.
990 * Modified backend interface. Request/Response struct's replaced by
991 one read/write C struct. For example bend_fetchrequest and
992 bend_fetchresult have been replaced by single bend_fetch_rr struct.
993 Every handler - even search has to be registered in bend_init
994 handler. This means that the YAZ library no longer refers to
995 external functions and it makes it possible to make the whole
996 thing a single DLL/SO.
998 Added Segment handler for backend server.
1000 Added Zmbol/Zebra administrative functions to YAZ client.
1002 Threaded frontend server on UNIX (when POSIX Threads are available).
1003 Starting the server with option -T enables multi-threading.
1007 Added configure option --enable-comp/disable-comp to control use
1008 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1009 located in sub directory asn.
1011 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1012 in ${exec_prefix}/bin along with the other programs yaz-client and
1015 GNU automake used to maintain makefiles.
1017 Added several OID's.
1019 Changed retrieval module so that we can load records with no abstract
1020 syntax defined. Tagpaths in these records are fully composed of string
1023 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1027 On UNIX, the generated makefile now supports a proper 'make install'.
1028 The prefix can be set via GNU configure to set the install location
1029 (default is /usr/local).
1031 * YAZ programs client and ztest were renamed to yaz-client and
1032 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1033 locations, such as /usr/bin,/usr/local/bin,etc.
1035 * YAZ Header files were moved from include to include/yaz. YAZ Header
1036 files are referred to as include <yaz/log.h> rather than <log.h>.
1037 The YAZ include path (-I ..) is therefore the same as before. Programmers
1038 should update their #include statements or use -Ipath/include/yaz
1039 instead. The main motivation for doing this change is that YAZ header files
1040 can be installed in "standard" locations /usr/include,/usr/local/include
1041 without introducing conflicts, since ALL YAZ header files are stored
1042 in subdirectory yaz (under /usr/include for example).
1044 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1045 rather than project/workspace files. We switched because project files
1046 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1049 Changed name of logging function, logf, to yaz_log, to prevent name
1050 clash with some math-log functions. The YAZ header log.h defines logf
1051 to yaz_log (#define) so there should be no incompatibilities by this
1054 Added bend_start/bend_stop handlers for server. These handler are
1055 called on start/stop of server. For windows they are called whenever
1056 a service is started/stopped.
1058 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1059 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1060 in util/yc.tcl. The auto-generated C code structures are, in a few
1061 cases, incompatible with the old decoders. There are differences in the
1062 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1063 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1064 The preprocessor variable ASN_COMPILED is defined when the compiled
1065 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1066 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1067 wish to use the old encoders/decoders you can specify --disable-yc
1070 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1071 version so that it supports both new - and old version of DB Update
1073 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1074 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1075 change. The name parameter can be set to 0 in which no name is specified
1076 for the construction. The macros odr_implicit and odr_explicit sets name
1077 parameter to zero for the construction involved. New macros
1078 odr_implicit_tag and odr_explicit_tag are similar to the others,
1079 except that a name parameter is added. For programmers' that don't use
1080 ODR they probably only need to change the call to z_APDU and z_External.
1082 Added access control facility by interfacing the TCP wrapper library.
1083 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1084 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1085 name of the daemon and enables the access control as specified in
1086 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1088 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1089 den Dool <H.M.vdnDool@kub.nl>.
1091 Added reference ID parameter to most functions in server API - refer
1092 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1094 Changed name of ccl library to libccl.a (was ccl.a).
1096 Fixed bug in decoder for Explain (Category TargetInfo).
1098 Added support for GNU readline in client. Thanks to Jacob Poulsen
1099 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1101 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1102 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1103 IMPLEMENTATION! This change was made to the development version before
1104 the ZIG decided to retract the amendment. If any users MUST be
1105 compatible with the original Update definition, PLEASE CONTACT US, and
1106 we will include a separate definition corresponding to the old Update
1107 ES. Note that because of the change to the ASN.1 of the
1108 TaskPackageRecordStructure we cannot define a single structure that
1109 will support both versions.
1111 * Added const modifier to buffer parameter for some ODR/BER encoding
1112 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1113 completeWAIS, odr_dumpBER.
1115 Fixed bug in client.c which caused a crash when a scanResponse didn't
1116 contain positionOfTerm.
1118 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1119 * will cause an error in a client if a non-YAZ target sends both a
1120 * list of Scan entries and non-surrogate diagnostics.
1122 Retrieval module enhancements. Tag sets may be typed in the reference
1123 to it. From the .abs-file the "tagset" directive takes a third optional
1124 integer type for the tag set referenced. From a .tag-file the "include"
1125 directive takes a third optional type as well. The old "type" directive
1126 in the tag set itself is still recognized but acts as the default type
1129 Backend interface change. Individual Scan terms returned from bend_scan
1130 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1131 in include/backend.h.
1133 Retrieval module enhancements. Multiple tag sets and attribute sets may
1134 be specified in abstract syntax specs. Revised the error/warning for
1135 logging messages reported by the retrieval module when reading the
1138 Object Identifier system (oid_..) changed. The API is backwards
1139 compatible but the oid-routines now allocates new OID's when needed.
1140 Raw OID's may be specified in oid_getvalbyname.
1142 YAZ now uses GNU configure to generate Makefile(s).
1144 * Minor changes in some of the member names of DeleteResultSetRequest and
1145 DeleteResultSetResponse. See include/proto.h.
1147 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1148 and added member 'languages' in TargetInfo (which was missing).
1150 Changed the way attribute sets are handled in the retrieval
1151 module. These are now cached, just like the abstract syntaxes
1154 Changed YAZ so that it links with compiled ASN.1.
1156 Added Explain-schema definitions and mapping routines. The following
1157 Explain categories have been implemented: AttributeDetails,
1158 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1160 Fixed minor bug in Windows version of Server Library.
1162 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1164 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1166 Added EXTERNAL: UNIverse Resource Report (non-standard).
1168 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1169 ENUMERATED and SET OF.
1171 * Added 'const' to some of the char pointer arguments for the
1172 functions, data1_read_node, data1_getelementbytagname,
1173 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1176 Fixed bug in data1_insert_taggeddata - the last_child member of
1177 parent wasn't initialised.
1179 * Changed data1_read_record and data1_read_node so that the supplied
1180 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1181 doesn't refer to any parts of the "SGML"-buffer.
1183 Fixed bug in server library (Windows version of statserv_remove).
1185 * Changed code so that it compiles as C++. The type definition
1186 of Odr_fun which is a member of Odr_arm was changed. The result is,
1187 that an explicit typecast is needed for the fun pointer when
1188 using Odr_arm - as in:
1189 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1191 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1193 Implemented the new structured date and time definition as approved
1194 by the ZIG. Added schemaId element to the specificTag in Espec-1
1195 (also approved at the last ZIG). Thanks to RVDM.
1197 Added some Object identifiers (RVDM).
1199 Changed the Update Extended Service (RVDM).
1201 Added command "refid" to client which specifies referenceId for
1202 the following requests.
1204 Implemented extended service handling for server. See ztest.c
1205 for an example as well as backend.h. New handlers are registerd
1206 in the Init handler.
1208 * Changed interface for sort in server.
1210 Added new members to statserv_options_block. It allows a server
1211 to read options from another source than just the command line. Thanks
1212 to Charles Woodfield.
1214 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1215 renamed to zboolean. Some C++ compilers complained about the name.
1217 Minor changes to gils.abs. Added index 's' (sort) on title
1218 and date/time-last-modified.
1220 --- 1.4pl2 1998/1/30
1222 Fixed bug in server library regarding inetd mode (-i). This bug
1223 was introduced by release 1.4.
1225 --- 1.4pl1 1998/1/29
1227 Added sort facility in client and backend server interface.
1229 Fixed problem with dependencies in Makefile(s).
1231 Fixed bugs for encoders/decoders of extended services and
1234 Implemented sub-tree feature for schemas. Sub-trees are
1235 referenced in *.abs-files. See explain.abs for an example
1236 of the use of this feature.
1238 Modified bib1.att; local attributes for ANY didn't include
1239 ANY itself (only affects use of the retrieval module).
1241 Fixed bug in plain SGML reader in function data1_read_node:
1242 tags with prefix "var" was incorrectly interpreted as variants.
1244 Added feature "sub-schemas" to enable references to - and definitions
1245 of - group of elements.
1247 * Removed member parent from type data1_element (in data1.h).
1249 Implemented function odr_nullval() that returns the value of
1252 * Removed member num_children from data1_node (in data1.h).
1254 Made NT service interface part of the server library. The
1255 function statserv_main uses the NT service when required and
1256 calls the statserv_start / statserv_close routines.
1258 Routine zget_SearchRequest and zget_PresentRequest fills
1259 resultSetName/Id member with "default" instead of "Default".
1261 Fixed memory leak in server. Request queue member wasn't freed.
1263 Fixed nmem_exit so that memory is freed.
1267 Revised the CCL parser utility to be thread safe.
1269 Added function, oid_ent_to_oid, to replace the function
1270 oid_getoidbyent, which is not thread safe.
1272 * Added nmem_init and nmem_exit to initialize and release
1273 NMEM resources. Function nmem_init should be called once in the
1274 initial thread before NMEM/ODR is used. statserv.c and client.c
1275 have been changed accordingly. The change was necessary to make
1276 NMEM thread safe. The NMEM memory pool is shared amongst threads
1277 in a process. Unix-based applications will still work fine without
1280 Added NT Services interface for the the Z39.50 (statserv) Server.
1281 Refer to the ztest.c source on the usage.
1283 Windows 95/NT port using MSVC5.0. Project files are included in the
1286 * Defined new 'global' handle for the retrieval (data1) system. The
1287 new handled, data1_handle, describes the state of the data1 system.
1288 This handle is passed as first argument to virtually all
1289 data1 related routines. The functions data1_create and data1_destroy
1290 creates and destroys a data1 handle respectively.
1292 Added ODR encode stream member to all backend request structures
1293 init, search, scan etc. This stream should be used to allocate all
1294 memory used for the response when thread safe operation is needed.
1296 Changed the comstack utility, cs_addstr, to be thread safe. The
1297 returned hostname string returned by the function is now part the
1300 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1301 function. The cs_straddr takes a COMSTACK handle as argument, so this
1302 function must be used after cs_create and before bind/connect.
1303 This function is thread safe.
1305 Moved test server to 'ztest' directory - generic server code still
1306 in 'server' directory.
1308 Made prefix query (pquery.c) utility thread safe.
1310 Added new function modifier YAZ_EXPORT to 'export' public DLL
1311 functions when using windows (see include/yconfig.h).
1313 Added definitions to the OID database (util/oid.c) (RVDM).
1315 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1317 Added call to ccl_rpn_delete in client program.
1319 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1320 release of RPN structure.
1322 Added support for C++, headers uses extern "C" for public definitions.
1323 With input from RVDM.
1325 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1326 Thanks to Ronald van der Meer (RVDM).
1328 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1330 Added support for private extensions to the OID database
1331 (oid_setprivateoids()). Thanks to RVDM.
1333 Added optional, physical ANY (key replication)
1335 Fixed null-reference problem in GRS-1 output filter.
1337 Proximity operator added to Prefix Query Format (PQF).
1339 In test client command "base" accepts multiple databases.
1341 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1345 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1347 Smallish bug-fixes in the new encoders/decoders (explain).
1349 Bug fixed in DeleteRequest.
1351 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1353 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1355 Added SOIF syntax (using private OID for now) to retrieval module and client.
1357 Added Update extended service.
1359 Added SearchResult-1 additional info structure.
1361 Added optional CCL (ISO8777) interpreter as separate module. Available
1364 --- 1.2 1996/6/10 (1st anniversary release)
1366 Added Summary record syntax. Lightly tested.
1368 Added OPAC record syntax. Untested.
1370 Added ResourceReport service encoders/decoders. Untested.
1372 Fixed bug in z_Unit - wrong tagging on unitSystem.
1374 Fixed bug in the DiagRecs decoder.
1376 Added options for max PDU size and session timeout to frontend-server.
1378 Added documentation of query-language parsers and other supporting utilities.
1380 [frontend-server] Added Attribute set to the bend_scanrequest API.
1382 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1383 surrogate diagnostics were generated.
1385 [retrieval] Allow multiple local values for attribute.
1387 [retrieval] Allow multiple attributes per element in .abs files. index type.
1389 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1391 --- 1.1pl2 1996/4/10
1393 Minor changes, mostly specific to Zebra's requirements (retrieval)
1397 Repaired bug in frontend server when running multiple listening
1398 endpoints in dynamic mode.
1400 z_External() now won't break if a known, ASN.1 value comes encapsulated
1401 in an octet-string. The value will pass through unmodified in an Odr_oct.
1403 Added a bit of code to the demo client to decode & display
1404 ASN.1-structured records represented in the octet-aligned branch of
1405 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1407 Added z_ext_getentbyref() to the ASN module. Doc updated.
1409 * Completed the SCAN definition in the ASN module. This may break SCAN
1410 code based on older YAZ-versions at compile-time. The fix is easy -
1413 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1414 under the SCAN definition. Remember to initialize this, server-people.
1416 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1417 that this does not extend to ODR and ASN.
1419 Comstack allows insertion of established socket (primarily for
1420 inetd-operation of servers). Doc updated.
1422 Front-end server can now start from the inetd in TCP mode. Doc
1425 --- 1.0pl4 1996/1/24
1429 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1430 the rank and record number.
1432 Adjustments to the frontend server.
1434 Fixed diagnostic BER dumper. It ignored the file argument.
1438 Various changes to retrieval module.
1440 Changed the union discriminators of the protocol files from enums to
1441 ints paired with #defines.
1443 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1446 *Changed operator in the RPN structure to 'roperator', again to avoid a
1449 Fixed problems in Explain decoders/encoders.
1451 --- 1.0pl2 1995/12/6
1453 Memory bug in log module fixed.
1455 --- 1.0pl1 1995/12/5
1457 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1459 Bug in Explain DatabaseInfo module fixed.
1461 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1465 The shift to v1.0 signals that we now consider the *core* functionality
1466 of YAZ reasonably stable (the core being more or less equivalent to
1467 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1468 tested (Explain not at all - though that will happen soonish).
1470 Minor changes to code to support Windows port.
1472 Various minor changes after we're getting to use GRS-1 & co. more.
1474 Added Espec-1 format.
1476 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1477 of the protocol and it cannot be selected when encoding (maps into 'string'
1478 when decoding). Needed to talk to some servers.
1480 Demo client can request simple element set names.
1482 Added Diagnostic Format encoders/decoders.
1484 Added simple Close handling to frontend server (no hooks for resource
1485 reporting yet), and demonstration client.
1487 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1489 --- 1.0b3 1995/08/24
1491 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1492 handled incorrectly when records were requested in the searchResponse. This
1493 will only affect you if you use the frontend-server.
1495 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1496 Test-client will ask for and print GRS1. Ztest will return dummy records
1499 Added Explain encoders/decoders to the service-level API. Untested.
1501 Added Extended Services: Item Order encoders and decoders to the Service-
1502 level API. Untested. We could use a recent copy of the pertinent bits
1503 of the ILL protocol to add those bits.
1505 Added diagnostic format 1 encoders/decoders to the service-level API.
1508 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1509 odr_cons.c, which causes a more correct output.
1511 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1512 was always set to 0 when no records were requested in the searchRequest.
1514 * Added better external-handling. This shouldn't harm old code that
1515 *encodes* externals. It can break code that looks for a
1516 'single-ASN1-type' representation, since those types that are known
1517 are now decoded immediately. Look at the SUTRS sample code in
1518 seshigh.c and client.c. Documentation updated.
1520 Handling of structured records in bend_fetchresponse. Length -1 marks
1521 structured record, type is deduced from format field.
1523 --- 1.0b2 1995/06/27
1524 Fairly quick maintenance release to add SUTRS support.
1526 Fixed handling of SUTRS records in the demonstration client.
1528 * Added format field to the bend_fetchrequest and bend_fetchresponce
1529 structures of the backend API (frontend server). When the record is
1530 returned, the value of the format field is mapped to an OID. The
1531 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1532 of the record. The special value VAL_NONE in the bend_request means
1533 that no specific format was requested by the client. Documentation
1534 updated accordingly. Test server (ztest) will return a fixed dummy
1535 SUTRS record if your client requests SUTRS.
1537 Documentation updated accordingly.
1539 You can now set external libraries and RANLIB support in the top-level
1543 First public release.
