1 Possible compatibility problems with earlier versions marked with '*'.
3 Added support for SRW scan in yaz-client and Generic Frontend Server.
5 * Added whereInList member to SRW Scan Term.
7 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
9 Fixed NMEM system to return aligned blocks on the smallest boundaries
10 that are suitably aligned for all possible types on the particular
11 architecture YAZ is being built for.
15 Fixed numerious warnings that was issued with newer versions of GCC.
17 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
18 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
21 Make YAZ Generic Frontend Server slightly faster.
23 Enhance (and reduce) logging for Generic Frontend Server.
25 Revert YAZ log system so that it flushes every write operation
26 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
28 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
29 instead of LOG_, due to name clash with syslog(3). LOG_ are still
30 present. New applications should define YAZ_USE_NEW_LOG=1 - this
31 will effectively disable old definitions.
35 Added yaz_log_time_format which specifies log format using
38 Added yaz_log_module_level which returns mask for a module. Value
39 is non-zero mask a if module is enabled; zero if disabled.
41 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
44 Fixed bug #176: Dont throw diagnostics on empty SRU args.
46 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
48 Fixed bug #172: RPM builds does not enable SSL.
50 Doxyfile.in part of dist. Doxyfile generated by configure.
52 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
53 are given and the corresponding component does not exist.
55 Extend CCL documentation in YAZ reference. Describe r=r.
59 Fixed MARC->MARCXML conversion to properly deal with
60 fields, subfields, indicators having non-ASCII characters.
62 Fixed MARC->MARCXML conversion so that ASCII control characters
63 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
66 Added YAZ GFS support for conversion from Z39.50 surrogate
67 diagnostics to SRW surrogate diagnostics.
69 Bug fix: YAZ GFS did not return schema in explainResponse.
73 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
74 now converts recordSchema to elementSetName as well as schema URI.
76 Fixed bug in COMSTACK that prevented HTTP request packages from being
81 Added CCL facility r=r "range" which is similar to r=o "ordered" but
82 does not require white-space before and after the dash in a range, e.g.
83 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
86 Fixed a few AC_TRY_LINK configure tests that did not operate properly
87 due to new GCC removing "redundant" code.
89 Added yaz-client commands scanpos and scanstep that sets preferred
90 position and step-size for scan.
92 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
94 Added CCL utility ccl_qual_buf which parses one or more CCL
95 spec lines in a buffer.
97 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
98 of name and value - ignoring empty lines and comments.
100 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
102 Added odr_get_element_path which returns current element path for an
103 ODR handle. This utility is useful in error handling or user-defined
106 Added ODR_PRINT utility odr_set_stream which is is a more generic
107 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
108 to a write function and pointer to close function. The close function - if
109 non-NULL - will be called during odr_destroy.
111 Fixed bug in CCL parser where truncation char was not removed from
112 right side when truncation=both was in effect.
114 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
117 --- 2.0.23 2004/08/11
119 Fix buffer overrun in CQL parser when dealing with proximity (%).
121 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
122 to UTF-8/UCS conversion is now only based on codetables.xml.
124 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
126 --- 2.0.22 2004/08/06
128 Add support for more "commit changes" in ZOOM (uses Extended Services).
130 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
133 Yet another small fix for configure of SSL.
135 --- 2.0.21 2004/05/14
137 Fix SSL libs for configure when --with-openssl=DIR is given.
139 --- 2.0.20 2004/05/10
141 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
143 SSL comstack now uses yaz.pem certificate file on server side
144 by default. Certificate filename can be configured by calling
145 comstack function cs_set_ssl_certificate_file before cs_bind is used.
147 Fix bug regarding multiple calls to ZOOM_connection_connect.
149 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
151 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
152 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
154 ZOOM now allows inspection of X509 peer certificate for verification.
155 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
157 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
158 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
159 as "modular" but it simplifies things.
161 Added cs_get_peer_certificate to that returns peer X509 PEM.
163 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
164 NULL if SSL is unavailable.
166 Documentation about MARC decoding tools.
168 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
170 --- 2.0.19 2004/03/30
172 Rename CHANGELOG to NEWS to follow GNU style packing.
174 Fix bug with missing initialization of member in init_diagnostics.
175 This bug affects threaded version of GFS server.
177 --- 2.0.18 2004/03/20
179 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
182 Ensure zlib.dll is packed with Windows install.
184 --- 2.0.17 2004/03/17
186 Fix encoding of xsd:string to use text instead of CDATA.
188 Fix endless loop in CQL parser with unbalanced ".
190 Use a more compact way to store MARC-8 conversion tables.
192 --- 2.0.16 2004/03/16 Debian only
194 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
197 Update CQL parser to use new CQL 1.1 modifiers for booleans and
202 --- 2.0.15 2004/03/01
204 Another fix for decoding of XML packed records.
206 --- 2.0.14 2004/02/25
208 Fixes for Chunked encoding. White space not ignored after length spec.
210 Update NS and use default NS for SRW diagnostic elements.
212 --- 2.0.13 2004/02/23
214 Implement ZOOM_resultset_cache_reset which resets record cache.
216 Implement ZOOM_resultset_sort which sorts a result set.
218 Implement chunked HTTP transfer.
220 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
222 --- 2.0.12 2004/02/16
224 Added member 'schema' to bend_explain_rr structure so that backend
225 can specify explain record identifier. Defaults to Zeerex 2.0.
227 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
229 --- 2.0.11 2004/02/16
231 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
234 Added init command for yaz-client which sends "extra" init request.
236 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
237 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
239 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
241 Make ZOOM error code for "invalid query".
243 Fixed compilation for SSL which wasn't properly enabled for all platforms.
245 --- 2.0.10 2004/02/05
247 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
250 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
252 Added option -p <file> to make Generic Frontend Server to write PID file.
254 Added option -D to put Generic Frontend Server in background on its own.
256 Make ZOOM C recognize option "password". If unset, "pass" is used
257 (for backwards compatibility).
259 Fixed a bug in Generic Frontend Server that could make it crash if a
260 client sets characterSetNegotation bit, but didn't pass negotiation stuff
263 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
264 Must be issued before open, in order to be in effect.
266 --- 2.0.9-6 2004/01/12 Debian/Windows
268 Make the SRU server more picky WRT unknown params, etc.
270 Bug fix: ZOOM scan response didn't return displayTerm - when present.
272 New YAZ client command, options, that sets Z39.50 options.
274 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
275 options from a string of tokens (one token for each option bit).
277 Update SRW diagnostic code messages.
279 --- 2.0.9-5 2004/01/07 Debian/Windows
281 Handle user defined stylesheet for SRW/SRU.
283 --- 2.0.9-4 2004/01/06 Debian/Windows
285 Fix bug in decoding of Content-Length.
287 --- 2.0.9-3 2004/01/06 Debian/Windows
289 Fix a bug with decoding of XML packed records.
291 --- 2.0.9-2 2004/01/05 Debian only
293 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
295 Fix bug in SRW/SRU diagnostics decoding.
299 Fixed bug in Generic Frontend Server which could drop records exceeding
300 preferred message size. Reported and fixed by Irina Dijour.
302 Fixed calculation of package size for structured records in Generic
303 Frontend Server. Reported and fixed by Irina Dijour.
305 Fixed namespace for SRW/SRU diagnostics.
307 Fixed SEGV in yaz-client that occured for HTTP connection errors.
311 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
312 this version is incompatible with version 1.0 and older YAZ SRW/SRU
315 CQL changes to reflect recent changes to the specification:
316 * Documentation talks about context sets instead of index sets.
317 * Documentation talks about indexes instead of qualifiers.
318 * The CQL-to-PQF transformer's configuration file now uses
319 "index.set.name = <attributes>" instead of the old form
320 "qualifier.set.name = <attributes>". (Both forms are still
321 understood but the latter is deprecated.)
322 * CQL terms with no explicit index specified are now interpreted as
323 cql.serverChoice instead of srw.serverChoice (which of course
324 behaves exactly the same.)
328 MARC conversion can now generate ISO2709 output in another
329 character set. yaz-marcdump uses this facility if you invoke it
332 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
333 functions from there can be used from C++.
337 Frontend server now transfers memory from decoded packages to stream
340 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
341 references to show up.
343 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
344 the ZOOM Abstract API. The older names for the same options are still
345 also supported for the benefit of old applications.
347 ZOOM-C supports "implementationId" and "implementationVersion" options
348 to go along with "implementationName". These allow the user code to
349 specify identification strings to be sent to servers.
350 Add OID for the new ExtLite attribute set.
352 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
353 as requested/supplid by Ere Maijala <ere@atp.fi>
355 For generic frontend server, reverse the order of
356 "toolkit-supplied / application-supplied" strings sent as implementationId,
357 Name and Version. Also, remove the spaces around the slash. This brings
358 the GFS in line with the behaviour of ZOOM-C on the client side.
360 Add function ZOOM_scanset_display_term.
362 yaz-client shows scan displayTerm if present.
364 Utility yaz-iconv is now installed by default along with the man page
367 Extend configure check for OpenSSL to use pkg-config where available (such
370 Incorporate patch by Morten Bogeskov which allows a Unix file socket
371 server to specify uid/gid/mask for socket using the format
372 unix:[user=uid,][group=gid,][umask=mask,]file=path
373 If file= is omitted the existing format is assumed, e.g.
375 in which case the mask is 0666 (rw for everybody).
377 Major restructure of YAZ source. All source in libyaz is in src directory.
378 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
379 util (utility programs such as ASN.1 compiler, yaz-marcdump).
381 Added man page for utility yaz-marcdump (used to be called marcdump).
382 yaz-marcdump is installed by 'make install'.
384 Fixed a memory leak in Generic Frontend Server that occurred when decoding
385 of incoming package failed.
387 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
389 Change prototype of odr_perror: add const to message string.
391 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
393 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
394 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
395 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
396 DNS lookup. There should not be any compatibility problems with this
397 assuming that blocking=1 or 0 is used.
399 Fix bad reference in UNIX comstack in function cs_addrstr.
401 Fix for compilation on AIX.
403 The generic front-end server (server/seshigh.c) now supports returning
404 Init diagnostics to the client in User-information-field, in
405 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
410 Allow any CQL relation (not just all,any,exact,scr).
412 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
413 that features the same UI.
415 Implemented command update0 in YAZ client which is equivalent to
416 update but uses old of Ext Update ASN.1.
418 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
419 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
420 Previously no OID was used for this info.
422 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
423 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
424 returns 'malformed search term' otherwise.
426 SortResponse member resultCount now set to NULL in sort handler of
429 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
432 Add three new utility functions for translating OIDs between various
433 formats -- symbolic name such as "Usmarc", minus-1-terminated int
434 arrays and dotted strings such as "1.2.840.10003.9.5.1":
435 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
436 char *oid_to_dotstring(const int *oid, char *oidbuf);
437 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
439 Reverted modifications for ES Update definition for z_IU0Update
440 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
441 is back to YAZ 2.0.2.
443 String value attributes for CCL parser.
445 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
446 which their FirstSearch server returns in Init responses, sometimes
447 carrying useful diagnostic information when Init fails. This has the
448 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
449 "z39.50/oclcui.asn", where its definition is somewhat different from
450 what OCLC document on their web-site, as required to interoperate with
453 Support for anonymous authentication in yaz-client. Use the command
456 * Fix the OID of the Index Data-local "admin" Extended Service from
457 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
458 the 1000, which indicates a locally-defined OID, was a mistake.
462 Fix CCL directive @case handling so that it affects string match for
463 both CCL keywords and qualifiers.
465 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
466 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
467 Decoder has been updated with ASN.1 changes as listed in
468 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
469 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
470 z_IUUpdate, remains unchanged.
472 ZOOM_record_get may now return a record in a specific character set.
473 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
474 "from" is the character set of record as returned by target. "to" is
475 the character set to be returned. If omitted, "to" is UTF-8.
477 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
479 New ODR utility, odr_getelement, which returns name of element for
480 which encoding/decoding failed.
482 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
483 in cases where a required element was omitted.
485 Bug fix: some MARC8 sequences were not converted.
487 New ZOOM option "step" which specifies number of records to be
488 retrieved in one chunk. Used in conjunction with "start" and "count".
490 SRW support for yaz-client. Use scheme http: to use it, e.g.
493 yaz-client no longer does (un)intelligent character set conversions
494 by default. Can be enabled with charset and marc_charset commands.
496 xmalloc trace fix for 64-bit systems such as DEC alpha.
498 Solaris 2.6 compile fix.
500 New function, cql_strerror() translates SRW error codes, as returned
501 by cql_transform_error(), into human-readable English strings. Used
502 in yaz-client diagnostics when appropriate.
504 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
505 converts it into a type-1 query which is sent to the server. This
506 makes CQL available for use with all Z-servers, as opposed to the tiny
507 minority that can handle CQL queries themselves.
511 New Debian package layout similar to the Redhat Package layout.
513 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
514 and search result respectively.
518 Redhat package is now several packages: libyaz (runtime libraries),
519 libyaz-devel (development and documentation, and yaz (utility programs).
520 Package spec file by Morten Bøgeskov.
522 New member 'schema' in struct bend_fetch_rr which the name of requested
523 schema (SRW/SRU) for record (or NULL if none was given). The fetch
524 handler MAY set this to reflect the schema of the returned record.
526 New member 'display_term' in struct scan_entry. GFS now sets member entries
527 and allocates scan entries to be filled by user scan handler. In previous
528 version, entries member was allocated by the scan handler. That still works,
529 but the GFS will ignore member display_term - assuming it was NOT set by
530 the handler. The fact that the GFS now allocates the entries both allows
531 for new members and makes a scan handler easier to write.
533 Fix CQL lex buffer overflow.
535 SRW/SRU recordPacking. For SRW default recordPacking is string. For
536 SRU default recordPacking is string.
538 SRU protocol support for frontend server.
540 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
542 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
544 Added scan for the ZOOM shell (zoomsh).
548 * String Identifers for Schemas (Amendment 5).
549 http://lcweb.loc.gov/z3950/agency/amend/am5.html
550 Old definition for schema
551 Odr_oid *schema; /* OPT */
556 Z_InternationalString *uri;
557 #define Z_Schema_oid 1
558 #define Z_Schema_uri 2
561 * resultCount parameter to Sort Response (Amendment 1).
562 http://lcweb.loc.gov/z3950/agency/amend/am1.html
564 Support for SRW 1.0 over HTTP. This is an optional feature and
565 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
568 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
569 on the same port. SRW SearchRetrieveRequests are mapped
570 to bend_init,bend_search,bend_fetch,bend_close.
572 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
574 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
575 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
577 ZOOM connections are SRW based if schem http is used for hostname
578 in connect, e.g. z = ZOOM_connection_new("http://myserver");
579 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
581 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
582 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
583 distance=n, order=true/false, relation=le, prox unit=word. If
584 n is omitted, distance 1 is used.
586 Fixed problem with C compiler include path in wrong order.
588 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
589 on Solaris. Patch from Ko van der Sloot.
591 New MARC decode API. All new functions operate on a yaz_marc_t
592 handle. The most important new functions are: yaz_marc_create,
593 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
594 decode and destroy respectively. Decoder can produce formats
595 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
596 include/yaz/marcdisp.h.
598 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
599 to UTF-8, UCS-32, wchar_t or Latin-1.
601 * Prototypes for yaz_iconv_-functions moved to separate header
602 include/yaz/yaz-iconv.h.
604 Make a few private functions 'static' in unix.c. This prevents
605 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
607 For ZOOM connection, the options targetImplementation{Id,Name,Version}
608 are set when Init Response is received.
610 New function ZOOM_connection_error_x similar to ZOOM_connection_error
611 but returns diagnostic set as well.
613 New function yaz_strerror which is a portable wrapper for
614 strerror/strerror_r/GetLastMessage.
616 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
617 is returned for MARC. If type is "oai", then OAI MARC is returned.
619 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
624 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
626 Fix bad race conditions on SIGTERM and terminate gracefully in
629 Move retrieval (data1) module to Zebra since nobody seems to be
632 Add GRS-1 render for ZOOM using same format as yaz-client.
636 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
638 Fix broken ESpec handling in data1 module.
640 SGML reader parses comments and makes them part of the data1 tree.
642 Added several type casts so that YAZ compiles as C++ code.
644 ZOOM didn't handle PDU encoding failures properly.
646 Added more Bib-1 diagnostics (approved extensions).
648 GNU configure: better check for iconv.
650 More portable use of accept, getpeername. Check for socklen_t. Use
651 int/size_t if socklen_t is not defined.
655 PQF parser rejects bad queries - including those with extra
656 characters in them. PQF parser used to silently ignore that.
657 Cleaner API for PQF added, which allows you to get detailed
658 error information for bad queries (see yaz/pquery.h).
660 Fixed bug in ZOOM_record_get for type "database".
662 Implemented mini iconv library supporting conversions between
663 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
665 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
669 Fixed ZOOM C record cache so that preferredRecordSyntax and
670 elementSetName is used to check for already fetched records.
674 Added three members in bend_initrequest structure to facilitate
675 character set negotiation.
677 Fixed a bug in frontend server that could cause indefinite
678 loops under rare conditions.
680 Revised character set utilities (charneg.h) so that encoding
681 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
683 For PQF, directive @term <type> sets term type for Scan/Search.
684 Here <type> is general, string, numeric, null. The term type
685 is inherited - just like @attr.
687 New call odr_set_charset that sets character set conversion for
688 international-strings on a ODR stream. Prototype is:
689 int odr_set_charset(ODR o, const char *to, const char *from);
690 The InternationalString is still represented as C string in YAZ
691 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
692 won't). On the protocol level, you can use any encoding.
694 Support for UNIX sockets in ZOOM.
696 Solaris recv sometimes returns errno == ENOENT. It is treated as
697 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
699 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
700 both client and server. Code by Morten Bøgeskov.
704 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
705 that they can be used directly from Visual Basic. You must recompile
706 your windows APP if you're using ZOOM.
708 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
709 Commands "lang" and "charset" sets language and character set respectively.
710 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
711 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
713 Attributes from multiple CCL fields may be OR'ed rather than merged
714 using directive "@field or". Fields are still merged by default -
715 equivalent to "@field merge".
717 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
720 Fixed bug in zget for parameter ExtendedServicesResponse.
726 Added PQF feature: '@attr type=value' may be written as '@type=value'.
728 Client displays USR.1:SearchResult-1 (hits per term).
730 Additional Search Info for search in Generic Frontend Server.
732 Fixed CCL parsing of "field=s".
734 WIN32 installer - using the excellent NSIS software from nullsoft.
736 Fixed CCL parsing of "field = - <number>".
738 Added function yaz_marc_decode that decodes MARC for line mode
739 display or XML (similar to that used by JZKit).
741 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
742 Z39.50. But ISO/ILL was, however.
744 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
745 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

748 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
752 New YAZ client features: Command completion and new commands:
753 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
754 Code provided by Jacob Poulsen.
756 New call oid_trav, that visits all registered OIDs via callback.
758 Function ZOOM_record_get now returns const char pointer rather than
759 void pointer. It saves a lot of type casts.
761 For YAZ client, command "auth" now allows you to set authentication
762 in IdPass style. It is enabled when three tokens are given - order
763 is user, group and password.
765 Fix memory leaks in MARC record handling for ZOOM.
767 New option for YAZ client, -k <kilobytes> that sets
768 maximum record size. Similar to -k option for generic frontend
769 server and yaz-ztest.
771 More fixes for scan. Non-zero stepSize handled. OID's fixes.
773 Prefix query parser reports "fail" when bad attribute set is given.
775 Fix in MARC decoder. Proximity logging. Fix for attribute set
776 in scan handler for server. Patches by Shigeru Ishida.
778 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
781 Configure option --with-openssl=<dir> now works when a directory is
782 specified. Patch provided by Morten Bøgeskov.
784 New option for YAZ client, -u <auth>, that sets authentication.
786 ZOOM fix: error information was sometimes "missing", since error
787 was cleared/reset too when it shouldn't.
789 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
793 Scan for ZOOM API. New object ZOOM_scanset. New functions
794 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
795 ZOOM_scanset_destroy.
797 New ZOOM function, ZOOM_connection_last_event, that returns type
798 of last event (such as "receive data", "send data", "apdu received",
801 New ZOOM option, schema, that specifies schema for retrieval.
803 New CCL feature. Qualifiers can be aliases for one or more
804 other qualifiers (if more than one is given, OR is used).
806 ZOOM uses named result sets if target supports it.
808 Two new YAZ client commands: . (dot, which sources a script of YAZ
809 client commands), and ! (to execute shell command.). Implemented
812 Working on Debian packages.
816 YAZ client enables named result sets only if target supports it.
818 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
820 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
821 with key="host" to get same result.
823 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
824 Function Z3950_resultset_record(s) returns references to records
825 "owned" by resultset. To become owner use Z3950_record_clone.
827 Function z_ext_record handles Extended Services. Thanks to
832 CCL Parser fix: ignore token comma when dealing with and-lists.
834 Documentation updates for COMSTACK.
836 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
837 Changed prototype Z3950_records. For some functions, int parameters
838 were changed to size_t.
840 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
843 New MARC decode/display function, marc_display_exl, which properly rejects
844 non-ISO2709 records. YAZ client uses it.
848 Fix bug: local attribute set wasn't set correctly in PQF strings.
852 * Old Z39.50 codecs no longer supported.
854 Added ZOOM C binding. See http://zoom.z3950.org/
856 Renamed states for COMSTACKs to avoid confusion with events.
858 Implemented cs_look and proper cs_rcvconnect.
860 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
862 Configure detects POSIX threads on OpenBSD.
864 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
865 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
867 When error is returned from present handler, non-surrogate diagnostic
868 is returned in present response (and fetch handler is no longer called).
870 * Minor adjustments to pquery parser (PQF). Token characters may be
871 escaped by using backslash (C-style).
873 PQF parser allows string attribute values to be specified. For @attr,
874 non-numeric characters after the equal-sign are treated as strings
875 (e.g. @attr 9=title).
877 CCL trunction character may be defined (@truncation in file)
879 * function zget_ExtendedServicesRequest sets waitAction to
880 waitIfPossible (was wait).
882 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
885 CCL operator names may be set in field definition files (CCL_bibset).
886 See ccl/bib1 for an example.
888 Fixes in ASN.1 compiler for C++ compatibility.
890 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
891 and "op_or" to avoid conflict with C++.
893 Fixed problem with GNU readline detection on Redhat 7.0.
895 Added step-size for Scan backend handler.
897 Fixed bug that made the frontend server crash when no attribute
898 set was specified for scan.
900 Front-end server automatically switches to original working directory
901 when installed as an NT service. Previously -w had to be specified to
904 Added extended attributes for retrieval module (data1), so that data1
905 records carry d1_readXML/SGML attributes. d1_read also supports
906 null-data rules ( <tag/>)
908 On UNIX when POSIX threads are available, a separate library libyazthread
909 is created. Programmers should link with that library and the yaz library
910 when using threads. The reason for the split was that some applications
911 on Linux, such as Apache, doesn't work well when using shared objects that
914 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
915 (or any frontend server) in SSL mode by specifying ssl: followed by
916 address. Only tested on UNIX.
918 Added feature for CCL module. Virtual structure s=al or s=ol generates
919 and-list and or-list respectively instead of phrase search.
923 * Added prefix "yaz_" for the functions log_init.., log_file.. and
924 log_mask_str. This was done to avoid name conflicts with other libraries
925 (such as other PHP extensions).
927 Added raw OID member for preferred record syntax (request_format_raw)
928 and returned record syntax (output_format_raw) for backend fetch method.
930 Config file yaz-config now accepts options so that it returns specific
931 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
933 Shared library support for UNIX using GNU libtool.
935 * Modified backend interface. Request/Response struct's replaced by
936 one read/write C struct. For example bend_fetchrequest and
937 bend_fetchresult have been replaced by single bend_fetch_rr struct.
938 Every handler - even search has to be registered in bend_init
939 handler. This means that the YAZ library no longer refers to
940 external functions and it makes it possible to make the whole
941 thing a single DLL/SO.
943 Added Segment handler for backend server.
945 Added Zmbol/Zebra administrative functions to YAZ client.
947 Threaded frontend server on UNIX (when POSIX Threads are available).
948 Starting the server with option -T enables multi-threading.
952 Added configure option --enable-comp/disable-comp to control use
953 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
954 located in sub directory asn.
956 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
957 in ${exec_prefix}/bin along with the other programs yaz-client and
960 GNU automake used to maintain makefiles.
964 Changed retrieval module so that we can load records with no abstract
965 syntax defined. Tagpaths in these records are fully composed of string
968 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
972 On UNIX, the generated makefile now supports a proper 'make install'.
973 The prefix can be set via GNU configure to set the install location
974 (default is /usr/local).
976 * YAZ programs client and ztest were renamed to yaz-client and
977 yaz-ztest to avoid conflicts when users install YAZ in "standard"
978 locations, such as /usr/bin,/usr/local/bin,etc.
980 * YAZ Header files were moved from include to include/yaz. YAZ Header
981 files are referred to as include <yaz/log.h> rather than <log.h>.
982 The YAZ include path (-I ..) is therefore the same as before. Programmers
983 should update their #include statements or use -Ipath/include/yaz
984 instead. The main motivation for doing this change is that YAZ header files
985 can be installed in "standard" locations /usr/include,/usr/local/include
986 without introducing conflicts, since ALL YAZ header files are stored
987 in subdirectory yaz (under /usr/include for example).
989 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
990 rather than project/workspace files. We switched because project files
991 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
994 Changed name of logging function, logf, to yaz_log, to prevent name
995 clash with some math-log functions. The YAZ header log.h defines logf
996 to yaz_log (#define) so there should be no incompatibilities by this
999 Added bend_start/bend_stop handlers for server. These handler are
1000 called on start/stop of server. For windows they are called whenever
1001 a service is started/stopped.
1003 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1004 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1005 in util/yc.tcl. The auto-generated C code structures are, in a few
1006 cases, incompatible with the old decoders. There are differences in the
1007 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1008 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1009 The preprocessor variable ASN_COMPILED is defined when the compiled
1010 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1011 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1012 wish to use the old encoders/decoders you can specify --disable-yc
1015 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1016 version so that it supports both new - and old version of DB Update
1018 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1019 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1020 change. The name parameter can be set to 0 in which no name is specified
1021 for the construction. The macros odr_implicit and odr_explicit sets name
1022 parameter to zero for the construction involved. New macros
1023 odr_implicit_tag and odr_explicit_tag are similar to the others,
1024 except that a name parameter is added. For programmers' that don't use
1025 ODR they probably only need to change the call to z_APDU and z_External.
1027 Added access control facility by interfacing the TCP wrapper library.
1028 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1029 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1030 name of the daemon and enables the access control as specified in
1031 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1033 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1034 den Dool <H.M.vdnDool@kub.nl>.
1036 Added reference ID parameter to most functions in server API - refer
1037 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1039 Changed name of ccl library to libccl.a (was ccl.a).
1041 Fixed bug in decoder for Explain (Category TargetInfo).
1043 Added support for GNU readline in client. Thanks to Jacob Poulsen
1044 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1046 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1047 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1048 IMPLEMENTATION! This change was made to the development version before
1049 the ZIG decided to retract the amendment. If any users MUST be
1050 compatible with the original Update definition, PLEASE CONTACT US, and
1051 we will include a separate definition corresponding to the old Update
1052 ES. Note that because of the change to the ASN.1 of the
1053 TaskPackageRecordStructure we cannot define a single structure that
1054 will support both versions.
1056 * Added const modifier to buffer parameter for some ODR/BER encoding
1057 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1058 completeWAIS, odr_dumpBER.
1060 Fixed bug in client.c which caused a crash when a scanResponse didn't
1061 contain positionOfTerm.
1063 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1064 * will cause an error in a client if a non-YAZ target sends both a
1065 * list of Scan entries and non-surrogate diagnostics.
1067 Retrieval module enhancements. Tag sets may be typed in the reference
1068 to it. From the .abs-file the "tagset" directive takes a third optional
1069 integer type for the tag set referenced. From a .tag-file the "include"
1070 directive takes a third optional type as well. The old "type" directive
1071 in the tag set itself is still recognized but acts as the default type
1074 Backend interface change. Individual Scan terms returned from bend_scan
1075 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1076 in include/backend.h.
1078 Retrieval module enhancements. Multiple tag sets and attribute sets may
1079 be specified in abstract syntax specs. Revised the error/warning for
1080 logging messages reported by the retrieval module when reading the
1083 Object Identifier system (oid_..) changed. The API is backwards
1084 compatible but the oid-routines now allocates new OID's when needed.
1085 Raw OID's may be specified in oid_getvalbyname.
1087 YAZ now uses GNU configure to generate Makefile(s).
1089 * Minor changes in some of the member names of DeleteResultSetRequest and
1090 DeleteResultSetResponse. See include/proto.h.
1092 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1093 and added member 'languages' in TargetInfo (which was missing).
1095 Changed the way attribute sets are handled in the retrieval
1096 module. These are now cached, just like the abstract syntaxes
1099 Changed YAZ so that it links with compiled ASN.1.
1101 Added Explain-schema definitions and mapping routines. The following
1102 Explain categories have been implemented: AttributeDetails,
1103 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1105 Fixed minor bug in Windows version of Server Library.
1107 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1109 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1111 Added EXTERNAL: UNIverse Resource Report (non-standard).
1113 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1114 ENUMERATED and SET OF.
1116 * Added 'const' to some of the char pointer arguments for the
1117 functions, data1_read_node, data1_getelementbytagname,
1118 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1121 Fixed bug in data1_insert_taggeddata - the last_child member of
1122 parent wasn't initialised.
1124 * Changed data1_read_record and data1_read_node so that the supplied
1125 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1126 doesn't refer to any parts of the "SGML"-buffer.
1128 Fixed bug in server library (Windows version of statserv_remove).
1130 * Changed code so that it compiles as C++. The type definition
1131 of Odr_fun which is a member of Odr_arm was changed. The result is,
1132 that an explicit typecast is needed for the fun pointer when
1133 using Odr_arm - as in:
1134 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1136 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1138 Implemented the new structured date and time definition as approved
1139 by the ZIG. Added schemaId element to the specificTag in Espec-1
1140 (also approved at the last ZIG). Thanks to RVDM.
1142 Added some Object identifiers (RVDM).
1144 Changed the Update Extended Service (RVDM).
1146 Added command "refid" to client which specifies referenceId for
1147 the following requests.
1149 Implemented extended service handling for server. See ztest.c
1150 for an example as well as backend.h. New handlers are registerd
1151 in the Init handler.
1153 * Changed interface for sort in server.
1155 Added new members to statserv_options_block. It allows a server
1156 to read options from another source than just the command line. Thanks
1157 to Charles Woodfield.
1159 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1160 renamed to zboolean. Some C++ compilers complained about the name.
1162 Minor changes to gils.abs. Added index 's' (sort) on title
1163 and date/time-last-modified.
1165 --- 1.4pl2 1998/1/30
1167 Fixed bug in server library regarding inetd mode (-i). This bug
1168 was introduced by release 1.4.
1170 --- 1.4pl1 1998/1/29
1172 Added sort facility in client and backend server interface.
1174 Fixed problem with dependencies in Makefile(s).
1176 Fixed bugs for encoders/decoders of extended services and
1179 Implemented sub-tree feature for schemas. Sub-trees are
1180 referenced in *.abs-files. See explain.abs for an example
1181 of the use of this feature.
1183 Modified bib1.att; local attributes for ANY didn't include
1184 ANY itself (only affects use of the retrieval module).
1186 Fixed bug in plain SGML reader in function data1_read_node:
1187 tags with prefix "var" was incorrectly interpreted as variants.
1189 Added feature "sub-schemas" to enable references to - and definitions
1190 of - group of elements.
1192 * Removed member parent from type data1_element (in data1.h).
1194 Implemented function odr_nullval() that returns the value of
1197 * Removed member num_children from data1_node (in data1.h).
1199 Made NT service interface part of the server library. The
1200 function statserv_main uses the NT service when required and
1201 calls the statserv_start / statserv_close routines.
1203 Routine zget_SearchRequest and zget_PresentRequest fills
1204 resultSetName/Id member with "default" instead of "Default".
1206 Fixed memory leak in server. Request queue member wasn't freed.
1208 Fixed nmem_exit so that memory is freed.
1212 Revised the CCL parser utility to be thread safe.
1214 Added function, oid_ent_to_oid, to replace the function
1215 oid_getoidbyent, which is not thread safe.
1217 * Added nmem_init and nmem_exit to initialize and release
1218 NMEM resources. Function nmem_init should be called once in the
1219 initial thread before NMEM/ODR is used. statserv.c and client.c
1220 have been changed accordingly. The change was necessary to make
1221 NMEM thread safe. The NMEM memory pool is shared amongst threads
1222 in a process. Unix-based applications will still work fine without
1225 Added NT Services interface for the the Z39.50 (statserv) Server.
1226 Refer to the ztest.c source on the usage.
1228 Windows 95/NT port using MSVC5.0. Project files are included in the
1231 * Defined new 'global' handle for the retrieval (data1) system. The
1232 new handled, data1_handle, describes the state of the data1 system.
1233 This handle is passed as first argument to virtually all
1234 data1 related routines. The functions data1_create and data1_destroy
1235 creates and destroys a data1 handle respectively.
1237 Added ODR encode stream member to all backend request structures
1238 init, search, scan etc. This stream should be used to allocate all
1239 memory used for the response when thread safe operation is needed.
1241 Changed the comstack utility, cs_addstr, to be thread safe. The
1242 returned hostname string returned by the function is now part the
1245 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1246 function. The cs_straddr takes a COMSTACK handle as argument, so this
1247 function must be used after cs_create and before bind/connect.
1248 This function is thread safe.
1250 Moved test server to 'ztest' directory - generic server code still
1251 in 'server' directory.
1253 Made prefix query (pquery.c) utility thread safe.
1255 Added new function modifier YAZ_EXPORT to 'export' public DLL
1256 functions when using windows (see include/yconfig.h).
1258 Added definitions to the OID database (util/oid.c) (RVDM).
1260 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1262 Added call to ccl_rpn_delete in client program.
1264 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1265 release of RPN structure.
1267 Added support for C++, headers uses extern "C" for public definitions.
1268 With input from RVDM.
1270 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1271 Thanks to Ronald van der Meer (RVDM).
1273 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1275 Added support for private extensions to the OID database
1276 (oid_setprivateoids()). Thanks to RVDM.
1278 Added optional, physical ANY (key replication)
1280 Fixed null-reference problem in GRS-1 output filter.
1282 Proximity operator added to Prefix Query Format (PQF).
1284 In test client command "base" accepts multiple databases.
1286 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1290 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1292 Smallish bug-fixes in the new encoders/decoders (explain).
1294 Bug fixed in DeleteRequest.
1296 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1298 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1300 Added SOIF syntax (using private OID for now) to retrieval module and client.
1302 Added Update extended service.
1304 Added SearchResult-1 additional info structure.
1306 Added optional CCL (ISO8777) interpreter as separate module. Available
1309 --- 1.2 1996/6/10 (1st anniversary release)
1311 Added Summary record syntax. Lightly tested.
1313 Added OPAC record syntax. Untested.
1315 Added ResourceReport service encoders/decoders. Untested.
1317 Fixed bug in z_Unit - wrong tagging on unitSystem.
1319 Fixed bug in the DiagRecs decoder.
1321 Added options for max PDU size and session timeout to frontend-server.
1323 Added documentation of query-language parsers and other supporting utilities.
1325 [frontend-server] Added Attribute set to the bend_scanrequest API.
1327 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1328 surrogate diagnostics were generated.
1330 [retrieval] Allow multiple local values for attribute.
1332 [retrieval] Allow multiple attributes per element in .abs files. index type.
1334 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1336 --- 1.1pl2 1996/4/10
1338 Minor changes, mostly specific to Zebra's requirements (retrieval)
1342 Repaired bug in frontend server when running multiple listening
1343 endpoints in dynamic mode.
1345 z_External() now won't break if a known, ASN.1 value comes encapsulated
1346 in an octet-string. The value will pass through unmodified in an Odr_oct.
1348 Added a bit of code to the demo client to decode & display
1349 ASN.1-structured records represented in the octet-aligned branch of
1350 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1352 Added z_ext_getentbyref() to the ASN module. Doc updated.
1354 * Completed the SCAN definition in the ASN module. This may break SCAN
1355 code based on older YAZ-versions at compile-time. The fix is easy -
1358 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1359 under the SCAN definition. Remember to initialize this, server-people.
1361 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1362 that this does not extend to ODR and ASN.
1364 Comstack allows insertion of established socket (primarily for
1365 inetd-operation of servers). Doc updated.
1367 Front-end server can now start from the inetd in TCP mode. Doc
1370 --- 1.0pl4 1996/1/24
1374 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1375 the rank and record number.
1377 Adjustments to the frontend server.
1379 Fixed diagnostic BER dumper. It ignored the file argument.
1383 Various changes to retrieval module.
1385 Changed the union discriminators of the protocol files from enums to
1386 ints paired with #defines.
1388 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1391 *Changed operator in the RPN structure to 'roperator', again to avoid a
1394 Fixed problems in Explain decoders/encoders.
1396 --- 1.0pl2 1995/12/6
1398 Memory bug in log module fixed.
1400 --- 1.0pl1 1995/12/5
1402 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1404 Bug in Explain DatabaseInfo module fixed.
1406 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1410 The shift to v1.0 signals that we now consider the *core* functionality
1411 of YAZ reasonably stable (the core being more or less equivalent to
1412 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1413 tested (Explain not at all - though that will happen soonish).
1415 Minor changes to code to support Windows port.
1417 Various minor changes after we're getting to use GRS-1 & co. more.
1419 Added Espec-1 format.
1421 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1422 of the protocol and it cannot be selected when encoding (maps into 'string'
1423 when decoding). Needed to talk to some servers.
1425 Demo client can request simple element set names.
1427 Added Diagnostic Format encoders/decoders.
1429 Added simple Close handling to frontend server (no hooks for resource
1430 reporting yet), and demonstration client.
1432 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1434 --- 1.0b3 1995/08/24
1436 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1437 handled incorrectly when records were requested in the searchResponse. This
1438 will only affect you if you use the frontend-server.
1440 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1441 Test-client will ask for and print GRS1. Ztest will return dummy records
1444 Added Explain encoders/decoders to the service-level API. Untested.
1446 Added Extended Services: Item Order encoders and decoders to the Service-
1447 level API. Untested. We could use a recent copy of the pertinent bits
1448 of the ILL protocol to add those bits.
1450 Added diagnostic format 1 encoders/decoders to the service-level API.
1453 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1454 odr_cons.c, which causes a more correct output.
1456 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1457 was always set to 0 when no records were requested in the searchRequest.
1459 * Added better external-handling. This shouldn't harm old code that
1460 *encodes* externals. It can break code that looks for a
1461 'single-ASN1-type' representation, since those types that are known
1462 are now decoded immediately. Look at the SUTRS sample code in
1463 seshigh.c and client.c. Documentation updated.
1465 Handling of structured records in bend_fetchresponse. Length -1 marks
1466 structured record, type is deduced from format field.
1468 --- 1.0b2 1995/06/27
1469 Fairly quick maintenance release to add SUTRS support.
1471 Fixed handling of SUTRS records in the demonstration client.
1473 * Added format field to the bend_fetchrequest and bend_fetchresponce
1474 structures of the backend API (frontend server). When the record is
1475 returned, the value of the format field is mapped to an OID. The
1476 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1477 of the record. The special value VAL_NONE in the bend_request means
1478 that no specific format was requested by the client. Documentation
1479 updated accordingly. Test server (ztest) will return a fixed dummy
1480 SUTRS record if your client requests SUTRS.
1482 Documentation updated accordingly.
1484 You can now set external libraries and RANLIB support in the top-level
1488 First public release.
