1 Possible compatibility problems with earlier versions marked with '*'.
3 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
7 Added member 'schema' to bend_explain_rr structure so that backend
8 can specify explain record identifier. Defaults to Zeerex 2.0.
10 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
14 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
17 Added init command for yaz-client which sends "extra" init request.
19 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
20 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
22 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
24 Make ZOOM error code for "invalid query".
26 Fixed compilation for SSL which wasn't properly enabled for all platforms.
30 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
33 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
35 Added option -p <file> to make Generic Frontend Server to write PID file.
37 Added option -D to put Generic Frontend Server in background on its own.
39 Make ZOOM C recognize option "password". If unset, "pass" is used
40 (for backwards compatibility).
42 Fixed a bug in Generic Frontend Server that could make it crash if a
43 client sets characterSetNegotation bit, but didn't pass negotiation stuff
46 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
47 Must be issued before open, in order to be in effect.
49 --- 2.0.9-6 2004/01/12 Debian/Windows
51 Make the SRU server more picky WRT unknown params, etc.
53 Bug fix: ZOOM scan response didn't return displayTerm - when present.
55 New YAZ client command, options, that sets Z39.50 options.
57 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
58 options from a string of tokens (one token for each option bit).
60 Update SRW diagnostic code messages.
62 --- 2.0.9-5 2004/01/07 Debian/Windows
64 Handle user defined stylesheet for SRW/SRU.
66 --- 2.0.9-4 2004/01/06 Debian/Windows
68 Fix bug in decoding of Content-Length.
70 --- 2.0.9-3 2004/01/06 Debian/Windows
72 Fix a bug with decoding of XML packed records.
74 --- 2.0.9-2 2004/01/05 Debian only
76 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
78 Fix bug in SRW/SRU diagnostics decoding.
82 Fixed bug in Generic Frontend Server which could drop records exceeding
83 preferred message size. Reported and fixed by Irina Dijour.
85 Fixed calculation of package size for structured records in Generic
86 Frontend Server. Reported and fixed by Irina Dijour.
88 Fixed namespace for SRW/SRU diagnostics.
90 Fixed SEGV in yaz-client that occured for HTTP connection errors.
94 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
95 this version is incompatible with version 1.0 and older YAZ SRW/SRU
98 CQL changes to reflect recent changes to the specification:
99 * Documentation talks about context sets instead of index sets.
100 * Documentation talks about indexes instead of qualifiers.
101 * The CQL-to-PQF transformer's configuration file now uses
102 "index.set.name = <attributes>" instead of the old form
103 "qualifier.set.name = <attributes>". (Both forms are still
104 understood but the latter is deprecated.)
105 * CQL terms with no explicit index specified are now interpreted as
106 cql.serverChoice instead of srw.serverChoice (which of course
107 behaves exactly the same.)
111 MARC conversion can now generate ISO2709 output in another
112 character set. yaz-marcdump uses this facility if you invoke it
115 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
116 functions from there can be used from C++.
120 Frontend server now transfers memory from decoded packages to stream
123 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
124 references to show up.
126 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
127 the ZOOM Abstract API. The older names for the same options are still
128 also supported for the benefit of old applications.
130 ZOOM-C supports "implementationId" and "implementationVersion" options
131 to go along with "implementationName". These allow the user code to
132 specify identification strings to be sent to servers.
133 Add OID for the new ExtLite attribute set.
135 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
136 as requested/supplid by Ere Maijala <ere@atp.fi>
138 For generic frontend server, reverse the order of
139 "toolkit-supplied / application-supplied" strings sent as implementationId,
140 Name and Version. Also, remove the spaces around the slash. This brings
141 the GFS in line with the behaviour of ZOOM-C on the client side.
143 Add function ZOOM_scanset_display_term.
145 yaz-client shows scan displayTerm if present.
147 Utility yaz-iconv is now installed by default along with the man page
150 Extend configure check for OpenSSL to use pkg-config where available (such
153 Incorporate patch by Morten Bogeskov which allows a Unix file socket
154 server to specify uid/gid/mask for socket using the format
155 unix:[user=uid,][group=gid,][umask=mask,]file=path
156 If file= is omitted the existing format is assumed, e.g.
158 in which case the mask is 0666 (rw for everybody).
160 Major restructure of YAZ source. All source in libyaz is in src directory.
161 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
162 util (utility programs such as ASN.1 compiler, yaz-marcdump).
164 Added man page for utility yaz-marcdump (used to be called marcdump).
165 yaz-marcdump is installed by 'make install'.
167 Fixed a memory leak in Generic Frontend Server that occurred when decoding
168 of incoming package failed.
170 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
172 Change prototype of odr_perror: add const to message string.
174 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
176 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
177 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
178 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
179 DNS lookup. There should not be any compatibility problems with this
180 assuming that blocking=1 or 0 is used.
182 Fix bad reference in UNIX comstack in function cs_addrstr.
184 Fix for compilation on AIX.
186 The generic front-end server (server/seshigh.c) now supports returning
187 Init diagnostics to the client in User-information-field, in
188 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
193 Allow any CQL relation (not just all,any,exact,scr).
195 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
196 that features the same UI.
198 Implemented command update0 in YAZ client which is equivalent to
199 update but uses old of Ext Update ASN.1.
201 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
202 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
203 Previously no OID was used for this info.
205 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
206 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
207 returns 'malformed search term' otherwise.
209 SortResponse member resultCount now set to NULL in sort handler of
212 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
215 Add three new utility functions for translating OIDs between various
216 formats -- symbolic name such as "Usmarc", minus-1-terminated int
217 arrays and dotted strings such as "1.2.840.10003.9.5.1":
218 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
219 char *oid_to_dotstring(const int *oid, char *oidbuf);
220 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
222 Reverted modifications for ES Update definition for z_IU0Update
223 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
224 is back to YAZ 2.0.2.
226 String value attributes for CCL parser.
228 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
229 which their FirstSearch server returns in Init responses, sometimes
230 carrying useful diagnostic information when Init fails. This has the
231 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
232 "z39.50/oclcui.asn", where its definition is somewhat different from
233 what OCLC document on their web-site, as required to interoperate with
236 Support for anonymous authentication in yaz-client. Use the command
239 * Fix the OID of the Index Data-local "admin" Extended Service from
240 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
241 the 1000, which indicates a locally-defined OID, was a mistake.
245 Fix CCL directive @case handling so that it affects string match for
246 both CCL keywords and qualifiers.
248 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
249 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
250 Decoder has been updated with ASN.1 changes as listed in
251 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
252 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
253 z_IUUpdate, remains unchanged.
255 ZOOM_record_get may now return a record in a specific character set.
256 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
257 "from" is the character set of record as returned by target. "to" is
258 the character set to be returned. If omitted, "to" is UTF-8.
260 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
262 New ODR utility, odr_getelement, which returns name of element for
263 which encoding/decoding failed.
265 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
266 in cases where a required element was omitted.
268 Bug fix: some MARC8 sequences were not converted.
270 New ZOOM option "step" which specifies number of records to be
271 retrieved in one chunk. Used in conjunction with "start" and "count".
273 SRW support for yaz-client. Use scheme http: to use it, e.g.
276 yaz-client no longer does (un)intelligent character set conversions
277 by default. Can be enabled with charset and marc_charset commands.
279 xmalloc trace fix for 64-bit systems such as DEC alpha.
281 Solaris 2.6 compile fix.
283 New function, cql_strerror() translates SRW error codes, as returned
284 by cql_transform_error(), into human-readable English strings. Used
285 in yaz-client diagnostics when appropriate.
287 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
288 converts it into a type-1 query which is sent to the server. This
289 makes CQL available for use with all Z-servers, as opposed to the tiny
290 minority that can handle CQL queries themselves.
294 New Debian package layout similar to the Redhat Package layout.
296 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
297 and search result respectively.
301 Redhat package is now several packages: libyaz (runtime libraries),
302 libyaz-devel (development and documentation, and yaz (utility programs).
303 Package spec file by Morten Bøgeskov.
305 New member 'schema' in struct bend_fetch_rr which the name of requested
306 schema (SRW/SRU) for record (or NULL if none was given). The fetch
307 handler MAY set this to reflect the schema of the returned record.
309 New member 'display_term' in struct scan_entry. GFS now sets member entries
310 and allocates scan entries to be filled by user scan handler. In previous
311 version, entries member was allocated by the scan handler. That still works,
312 but the GFS will ignore member display_term - assuming it was NOT set by
313 the handler. The fact that the GFS now allocates the entries both allows
314 for new members and makes a scan handler easier to write.
316 Fix CQL lex buffer overflow.
318 SRW/SRU recordPacking. For SRW default recordPacking is string. For
319 SRU default recordPacking is string.
321 SRU protocol support for frontend server.
323 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
325 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
327 Added scan for the ZOOM shell (zoomsh).
331 * String Identifers for Schemas (Amendment 5).
332 http://lcweb.loc.gov/z3950/agency/amend/am5.html
333 Old definition for schema
334 Odr_oid *schema; /* OPT */
339 Z_InternationalString *uri;
340 #define Z_Schema_oid 1
341 #define Z_Schema_uri 2
344 * resultCount parameter to Sort Response (Amendment 1).
345 http://lcweb.loc.gov/z3950/agency/amend/am1.html
347 Support for SRW 1.0 over HTTP. This is an optional feature and
348 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
351 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
352 on the same port. SRW SearchRetrieveRequests are mapped
353 to bend_init,bend_search,bend_fetch,bend_close.
355 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
357 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
358 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
360 ZOOM connections are SRW based if schem http is used for hostname
361 in connect, e.g. z = ZOOM_connection_new("http://myserver");
362 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
364 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
365 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
366 distance=n, order=true/false, relation=le, prox unit=word. If
367 n is omitted, distance 1 is used.
369 Fixed problem with C compiler include path in wrong order.
371 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
372 on Solaris. Patch from Ko van der Sloot.
374 New MARC decode API. All new functions operate on a yaz_marc_t
375 handle. The most important new functions are: yaz_marc_create,
376 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
377 decode and destroy respectively. Decoder can produce formats
378 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
379 include/yaz/marcdisp.h.
381 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
382 to UTF-8, UCS-32, wchar_t or Latin-1.
384 * Prototypes for yaz_iconv_-functions moved to separate header
385 include/yaz/yaz-iconv.h.
387 Make a few private functions 'static' in unix.c. This prevents
388 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
390 For ZOOM connection, the options targetImplementation{Id,Name,Version}
391 are set when Init Response is received.
393 New function ZOOM_connection_error_x similar to ZOOM_connection_error
394 but returns diagnostic set as well.
396 New function yaz_strerror which is a portable wrapper for
397 strerror/strerror_r/GetLastMessage.
399 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
400 is returned for MARC. If type is "oai", then OAI MARC is returned.
402 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
407 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
409 Fix bad race conditions on SIGTERM and terminate gracefully in
412 Move retrieval (data1) module to Zebra since nobody seems to be
415 Add GRS-1 render for ZOOM using same format as yaz-client.
419 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
421 Fix broken ESpec handling in data1 module.
423 SGML reader parses comments and makes them part of the data1 tree.
425 Added several type casts so that YAZ compiles as C++ code.
427 ZOOM didn't handle PDU encoding failures properly.
429 Added more Bib-1 diagnostics (approved extensions).
431 GNU configure: better check for iconv.
433 More portable use of accept, getpeername. Check for socklen_t. Use
434 int/size_t if socklen_t is not defined.
438 PQF parser rejects bad queries - including those with extra
439 characters in them. PQF parser used to silently ignore that.
440 Cleaner API for PQF added, which allows you to get detailed
441 error information for bad queries (see yaz/pquery.h).
443 Fixed bug in ZOOM_record_get for type "database".
445 Implemented mini iconv library supporting conversions between
446 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
448 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
452 Fixed ZOOM C record cache so that preferredRecordSyntax and
453 elementSetName is used to check for already fetched records.
457 Added three members in bend_initrequest structure to facilitate
458 character set negotiation.
460 Fixed a bug in frontend server that could cause indefinite
461 loops under rare conditions.
463 Revised character set utilities (charneg.h) so that encoding
464 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
466 For PQF, directive @term <type> sets term type for Scan/Search.
467 Here <type> is general, string, numeric, null. The term type
468 is inherited - just like @attr.
470 New call odr_set_charset that sets character set conversion for
471 international-strings on a ODR stream. Prototype is:
472 int odr_set_charset(ODR o, const char *to, const char *from);
473 The InternationalString is still represented as C string in YAZ
474 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
475 won't). On the protocol level, you can use any encoding.
477 Support for UNIX sockets in ZOOM.
479 Solaris recv sometimes returns errno == ENOENT. It is treated as
480 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
482 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
483 both client and server. Code by Morten Bøgeskov.
487 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
488 that they can be used directly from Visual Basic. You must recompile
489 your windows APP if you're using ZOOM.
491 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
492 Commands "lang" and "charset" sets language and character set respectively.
493 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
494 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
496 Attributes from multiple CCL fields may be OR'ed rather than merged
497 using directive "@field or". Fields are still merged by default -
498 equivalent to "@field merge".
500 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
503 Fixed bug in zget for parameter ExtendedServicesResponse.
509 Added PQF feature: '@attr type=value' may be written as '@type=value'.
511 Client displays USR.1:SearchResult-1 (hits per term).
513 Additional Search Info for search in Generic Frontend Server.
515 Fixed CCL parsing of "field=s".
517 WIN32 installer - using the excellent NSIS software from nullsoft.
519 Fixed CCL parsing of "field = - <number>".
521 Added function yaz_marc_decode that decodes MARC for line mode
522 display or XML (similar to that used by JZKit).
524 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
525 Z39.50. But ISO/ILL was, however.
527 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
528 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
530 http://lcweb.loc.gov/z3950/agency/amend/am2.html
531 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
535 New YAZ client features: Command completion and new commands:
536 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
537 Code provided by Jacob Poulsen.
539 New call oid_trav, that visits all registered OIDs via callback.
541 Function ZOOM_record_get now returns const char pointer rather than
542 void pointer. It saves a lot of type casts.
544 For YAZ client, command "auth" now allows you to set authentication
545 in IdPass style. It is enabled when three tokens are given - order
546 is user, group and password.
548 Fix memory leaks in MARC record handling for ZOOM.
550 New option for YAZ client, -k <kilobytes> that sets
551 maximum record size. Similar to -k option for generic frontend
552 server and yaz-ztest.
554 More fixes for scan. Non-zero stepSize handled. OID's fixes.
556 Prefix query parser reports "fail" when bad attribute set is given.
558 Fix in MARC decoder. Proximity logging. Fix for attribute set
559 in scan handler for server. Patches by Shigeru Ishida.
561 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
564 Configure option --with-openssl=<dir> now works when a directory is
565 specified. Patch provided by Morten Bøgeskov.
567 New option for YAZ client, -u <auth>, that sets authentication.
569 ZOOM fix: error information was sometimes "missing", since error
570 was cleared/reset too when it shouldn't.
572 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
576 Scan for ZOOM API. New object ZOOM_scanset. New functions
577 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
578 ZOOM_scanset_destroy.
580 New ZOOM function, ZOOM_connection_last_event, that returns type
581 of last event (such as "receive data", "send data", "apdu received",
584 New ZOOM option, schema, that specifies schema for retrieval.
586 New CCL feature. Qualifiers can be aliases for one or more
587 other qualifiers (if more than one is given, OR is used).
589 ZOOM uses named result sets if target supports it.
591 Two new YAZ client commands: . (dot, which sources a script of YAZ
592 client commands), and ! (to execute shell command.). Implemented
595 Working on Debian packages.
599 YAZ client enables named result sets only if target supports it.
601 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
603 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
604 with key="host" to get same result.
606 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
607 Function Z3950_resultset_record(s) returns references to records
608 "owned" by resultset. To become owner use Z3950_record_clone.
610 Function z_ext_record handles Extended Services. Thanks to
615 CCL Parser fix: ignore token comma when dealing with and-lists.
617 Documentation updates for COMSTACK.
619 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
620 Changed prototype Z3950_records. For some functions, int parameters
621 were changed to size_t.
623 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
626 New MARC decode/display function, marc_display_exl, which properly rejects
627 non-ISO2709 records. YAZ client uses it.
631 Fix bug: local attribute set wasn't set correctly in PQF strings.
635 * Old Z39.50 codecs no longer supported.
637 Added ZOOM C binding. See http://zoom.z3950.org/
639 Renamed states for COMSTACKs to avoid confusion with events.
641 Implemented cs_look and proper cs_rcvconnect.
643 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
645 Configure detects POSIX threads on OpenBSD.
647 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
648 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
650 When error is returned from present handler, non-surrogate diagnostic
651 is returned in present response (and fetch handler is no longer called).
653 * Minor adjustments to pquery parser (PQF). Token characters may be
654 escaped by using backslash (C-style).
656 PQF parser allows string attribute values to be specified. For @attr,
657 non-numeric characters after the equal-sign are treated as strings
658 (e.g. @attr 9=title).
660 CCL trunction character may be defined (@truncation in file)
662 * function zget_ExtendedServicesRequest sets waitAction to
663 waitIfPossible (was wait).
665 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
668 CCL operator names may be set in field definition files (CCL_bibset).
669 See ccl/bib1 for an example.
671 Fixes in ASN.1 compiler for C++ compatibility.
673 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
674 and "op_or" to avoid conflict with C++.
676 Fixed problem with GNU readline detection on Redhat 7.0.
678 Added step-size for Scan backend handler.
680 Fixed bug that made the frontend server crash when no attribute
681 set was specified for scan.
683 Front-end server automatically switches to original working directory
684 when installed as an NT service. Previously -w had to be specified to
687 Added extended attributes for retrieval module (data1), so that data1
688 records carry d1_readXML/SGML attributes. d1_read also supports
689 null-data rules ( <tag/>)
691 On UNIX when POSIX threads are available, a separate library libyazthread
692 is created. Programmers should link with that library and the yaz library
693 when using threads. The reason for the split was that some applications
694 on Linux, such as Apache, doesn't work well when using shared objects that
697 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
698 (or any frontend server) in SSL mode by specifying ssl: followed by
699 address. Only tested on UNIX.
701 Added feature for CCL module. Virtual structure s=al or s=ol generates
702 and-list and or-list respectively instead of phrase search.
706 * Added prefix "yaz_" for the functions log_init.., log_file.. and
707 log_mask_str. This was done to avoid name conflicts with other libraries
708 (such as other PHP extensions).
710 Added raw OID member for preferred record syntax (request_format_raw)
711 and returned record syntax (output_format_raw) for backend fetch method.
713 Config file yaz-config now accepts options so that it returns specific
714 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
716 Shared library support for UNIX using GNU libtool.
718 * Modified backend interface. Request/Response struct's replaced by
719 one read/write C struct. For example bend_fetchrequest and
720 bend_fetchresult have been replaced by single bend_fetch_rr struct.
721 Every handler - even search has to be registered in bend_init
722 handler. This means that the YAZ library no longer refers to
723 external functions and it makes it possible to make the whole
724 thing a single DLL/SO.
726 Added Segment handler for backend server.
728 Added Zmbol/Zebra administrative functions to YAZ client.
730 Threaded frontend server on UNIX (when POSIX Threads are available).
731 Starting the server with option -T enables multi-threading.
735 Added configure option --enable-comp/disable-comp to control use
736 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
737 located in sub directory asn.
739 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
740 in ${exec_prefix}/bin along with the other programs yaz-client and
743 GNU automake used to maintain makefiles.
747 Changed retrieval module so that we can load records with no abstract
748 syntax defined. Tagpaths in these records are fully composed of string
751 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
755 On UNIX, the generated makefile now supports a proper 'make install'.
756 The prefix can be set via GNU configure to set the install location
757 (default is /usr/local).
759 * YAZ programs client and ztest were renamed to yaz-client and
760 yaz-ztest to avoid conflicts when users install YAZ in "standard"
761 locations, such as /usr/bin,/usr/local/bin,etc.
763 * YAZ Header files were moved from include to include/yaz. YAZ Header
764 files are referred to as include <yaz/log.h> rather than <log.h>.
765 The YAZ include path (-I ..) is therefore the same as before. Programmers
766 should update their #include statements or use -Ipath/include/yaz
767 instead. The main motivation for doing this change is that YAZ header files
768 can be installed in "standard" locations /usr/include,/usr/local/include
769 without introducing conflicts, since ALL YAZ header files are stored
770 in subdirectory yaz (under /usr/include for example).
772 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
773 rather than project/workspace files. We switched because project files
774 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
777 Changed name of logging function, logf, to yaz_log, to prevent name
778 clash with some math-log functions. The YAZ header log.h defines logf
779 to yaz_log (#define) so there should be no incompatibilities by this
782 Added bend_start/bend_stop handlers for server. These handler are
783 called on start/stop of server. For windows they are called whenever
784 a service is started/stopped.
786 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
787 a fairly small ASN.1 compiler written in Tcl. The compiler is located
788 in util/yc.tcl. The auto-generated C code structures are, in a few
789 cases, incompatible with the old decoders. There are differences in the
790 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
791 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
792 The preprocessor variable ASN_COMPILED is defined when the compiled
793 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
794 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
795 wish to use the old encoders/decoders you can specify --disable-yc
798 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
799 version so that it supports both new - and old version of DB Update
801 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
802 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
803 change. The name parameter can be set to 0 in which no name is specified
804 for the construction. The macros odr_implicit and odr_explicit sets name
805 parameter to zero for the construction involved. New macros
806 odr_implicit_tag and odr_explicit_tag are similar to the others,
807 except that a name parameter is added. For programmers' that don't use
808 ODR they probably only need to change the call to z_APDU and z_External.
810 Added access control facility by interfacing the TCP wrapper library.
811 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
812 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
813 name of the daemon and enables the access control as specified in
814 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
816 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
817 den Dool <H.M.vdnDool@kub.nl>.
819 Added reference ID parameter to most functions in server API - refer
820 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
822 Changed name of ccl library to libccl.a (was ccl.a).
824 Fixed bug in decoder for Explain (Category TargetInfo).
826 Added support for GNU readline in client. Thanks to Jacob Poulsen
827 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
829 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
830 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
831 IMPLEMENTATION! This change was made to the development version before
832 the ZIG decided to retract the amendment. If any users MUST be
833 compatible with the original Update definition, PLEASE CONTACT US, and
834 we will include a separate definition corresponding to the old Update
835 ES. Note that because of the change to the ASN.1 of the
836 TaskPackageRecordStructure we cannot define a single structure that
837 will support both versions.
839 * Added const modifier to buffer parameter for some ODR/BER encoding
840 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
841 completeWAIS, odr_dumpBER.
843 Fixed bug in client.c which caused a crash when a scanResponse didn't
844 contain positionOfTerm.
846 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
847 * will cause an error in a client if a non-YAZ target sends both a
848 * list of Scan entries and non-surrogate diagnostics.
850 Retrieval module enhancements. Tag sets may be typed in the reference
851 to it. From the .abs-file the "tagset" directive takes a third optional
852 integer type for the tag set referenced. From a .tag-file the "include"
853 directive takes a third optional type as well. The old "type" directive
854 in the tag set itself is still recognized but acts as the default type
857 Backend interface change. Individual Scan terms returned from bend_scan
858 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
859 in include/backend.h.
861 Retrieval module enhancements. Multiple tag sets and attribute sets may
862 be specified in abstract syntax specs. Revised the error/warning for
863 logging messages reported by the retrieval module when reading the
866 Object Identifier system (oid_..) changed. The API is backwards
867 compatible but the oid-routines now allocates new OID's when needed.
868 Raw OID's may be specified in oid_getvalbyname.
870 YAZ now uses GNU configure to generate Makefile(s).
872 * Minor changes in some of the member names of DeleteResultSetRequest and
873 DeleteResultSetResponse. See include/proto.h.
875 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
876 and added member 'languages' in TargetInfo (which was missing).
878 Changed the way attribute sets are handled in the retrieval
879 module. These are now cached, just like the abstract syntaxes
882 Changed YAZ so that it links with compiled ASN.1.
884 Added Explain-schema definitions and mapping routines. The following
885 Explain categories have been implemented: AttributeDetails,
886 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
888 Fixed minor bug in Windows version of Server Library.
890 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
892 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
894 Added EXTERNAL: UNIverse Resource Report (non-standard).
896 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
897 ENUMERATED and SET OF.
899 * Added 'const' to some of the char pointer arguments for the
900 functions, data1_read_node, data1_getelementbytagname,
901 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
904 Fixed bug in data1_insert_taggeddata - the last_child member of
905 parent wasn't initialised.
907 * Changed data1_read_record and data1_read_node so that the supplied
908 "SGML"-buffer is read-only. In particular the resulting data1 - tree
909 doesn't refer to any parts of the "SGML"-buffer.
911 Fixed bug in server library (Windows version of statserv_remove).
913 * Changed code so that it compiles as C++. The type definition
914 of Odr_fun which is a member of Odr_arm was changed. The result is,
915 that an explicit typecast is needed for the fun pointer when
916 using Odr_arm - as in:
917 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
919 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
921 Implemented the new structured date and time definition as approved
922 by the ZIG. Added schemaId element to the specificTag in Espec-1
923 (also approved at the last ZIG). Thanks to RVDM.
925 Added some Object identifiers (RVDM).
927 Changed the Update Extended Service (RVDM).
929 Added command "refid" to client which specifies referenceId for
930 the following requests.
932 Implemented extended service handling for server. See ztest.c
933 for an example as well as backend.h. New handlers are registerd
936 * Changed interface for sort in server.
938 Added new members to statserv_options_block. It allows a server
939 to read options from another source than just the command line. Thanks
940 to Charles Woodfield.
942 * Changed definition of Z_Triple in file prt-grs.h - member boolean
943 renamed to zboolean. Some C++ compilers complained about the name.
945 Minor changes to gils.abs. Added index 's' (sort) on title
946 and date/time-last-modified.
950 Fixed bug in server library regarding inetd mode (-i). This bug
951 was introduced by release 1.4.
955 Added sort facility in client and backend server interface.
957 Fixed problem with dependencies in Makefile(s).
959 Fixed bugs for encoders/decoders of extended services and
962 Implemented sub-tree feature for schemas. Sub-trees are
963 referenced in *.abs-files. See explain.abs for an example
964 of the use of this feature.
966 Modified bib1.att; local attributes for ANY didn't include
967 ANY itself (only affects use of the retrieval module).
969 Fixed bug in plain SGML reader in function data1_read_node:
970 tags with prefix "var" was incorrectly interpreted as variants.
972 Added feature "sub-schemas" to enable references to - and definitions
973 of - group of elements.
975 * Removed member parent from type data1_element (in data1.h).
977 Implemented function odr_nullval() that returns the value of
980 * Removed member num_children from data1_node (in data1.h).
982 Made NT service interface part of the server library. The
983 function statserv_main uses the NT service when required and
984 calls the statserv_start / statserv_close routines.
986 Routine zget_SearchRequest and zget_PresentRequest fills
987 resultSetName/Id member with "default" instead of "Default".
989 Fixed memory leak in server. Request queue member wasn't freed.
991 Fixed nmem_exit so that memory is freed.
995 Revised the CCL parser utility to be thread safe.
997 Added function, oid_ent_to_oid, to replace the function
998 oid_getoidbyent, which is not thread safe.
1000 * Added nmem_init and nmem_exit to initialize and release
1001 NMEM resources. Function nmem_init should be called once in the
1002 initial thread before NMEM/ODR is used. statserv.c and client.c
1003 have been changed accordingly. The change was necessary to make
1004 NMEM thread safe. The NMEM memory pool is shared amongst threads
1005 in a process. Unix-based applications will still work fine without
1008 Added NT Services interface for the the Z39.50 (statserv) Server.
1009 Refer to the ztest.c source on the usage.
1011 Windows 95/NT port using MSVC5.0. Project files are included in the
1014 * Defined new 'global' handle for the retrieval (data1) system. The
1015 new handled, data1_handle, describes the state of the data1 system.
1016 This handle is passed as first argument to virtually all
1017 data1 related routines. The functions data1_create and data1_destroy
1018 creates and destroys a data1 handle respectively.
1020 Added ODR encode stream member to all backend request structures
1021 init, search, scan etc. This stream should be used to allocate all
1022 memory used for the response when thread safe operation is needed.
1024 Changed the comstack utility, cs_addstr, to be thread safe. The
1025 returned hostname string returned by the function is now part the
1028 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1029 function. The cs_straddr takes a COMSTACK handle as argument, so this
1030 function must be used after cs_create and before bind/connect.
1031 This function is thread safe.
1033 Moved test server to 'ztest' directory - generic server code still
1034 in 'server' directory.
1036 Made prefix query (pquery.c) utility thread safe.
1038 Added new function modifier YAZ_EXPORT to 'export' public DLL
1039 functions when using windows (see include/yconfig.h).
1041 Added definitions to the OID database (util/oid.c) (RVDM).
1043 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1045 Added call to ccl_rpn_delete in client program.
1047 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1048 release of RPN structure.
1050 Added support for C++, headers uses extern "C" for public definitions.
1051 With input from RVDM.
1053 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1054 Thanks to Ronald van der Meer (RVDM).
1056 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1058 Added support for private extensions to the OID database
1059 (oid_setprivateoids()). Thanks to RVDM.
1061 Added optional, physical ANY (key replication)
1063 Fixed null-reference problem in GRS-1 output filter.
1065 Proximity operator added to Prefix Query Format (PQF).
1067 In test client command "base" accepts multiple databases.
1069 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1073 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1075 Smallish bug-fixes in the new encoders/decoders (explain).
1077 Bug fixed in DeleteRequest.
1079 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1081 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1083 Added SOIF syntax (using private OID for now) to retrieval module and client.
1085 Added Update extended service.
1087 Added SearchResult-1 additional info structure.
1089 Added optional CCL (ISO8777) interpreter as separate module. Available
1092 --- 1.2 1996/6/10 (1st anniversary release)
1094 Added Summary record syntax. Lightly tested.
1096 Added OPAC record syntax. Untested.
1098 Added ResourceReport service encoders/decoders. Untested.
1100 Fixed bug in z_Unit - wrong tagging on unitSystem.
1102 Fixed bug in the DiagRecs decoder.
1104 Added options for max PDU size and session timeout to frontend-server.
1106 Added documentation of query-language parsers and other supporting utilities.
1108 [frontend-server] Added Attribute set to the bend_scanrequest API.
1110 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1111 surrogate diagnostics were generated.
1113 [retrieval] Allow multiple local values for attribute.
1115 [retrieval] Allow multiple attributes per element in .abs files. index type.
1117 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1119 --- 1.1pl2 1996/4/10
1121 Minor changes, mostly specific to Zebra's requirements (retrieval)
1125 Repaired bug in frontend server when running multiple listening
1126 endpoints in dynamic mode.
1128 z_External() now won't break if a known, ASN.1 value comes encapsulated
1129 in an octet-string. The value will pass through unmodified in an Odr_oct.
1131 Added a bit of code to the demo client to decode & display
1132 ASN.1-structured records represented in the octet-aligned branch of
1133 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1135 Added z_ext_getentbyref() to the ASN module. Doc updated.
1137 * Completed the SCAN definition in the ASN module. This may break SCAN
1138 code based on older YAZ-versions at compile-time. The fix is easy -
1141 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1142 under the SCAN definition. Remember to initialize this, server-people.
1144 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1145 that this does not extend to ODR and ASN.
1147 Comstack allows insertion of established socket (primarily for
1148 inetd-operation of servers). Doc updated.
1150 Front-end server can now start from the inetd in TCP mode. Doc
1153 --- 1.0pl4 1996/1/24
1157 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1158 the rank and record number.
1160 Adjustments to the frontend server.
1162 Fixed diagnostic BER dumper. It ignored the file argument.
1166 Various changes to retrieval module.
1168 Changed the union discriminators of the protocol files from enums to
1169 ints paired with #defines.
1171 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1174 *Changed operator in the RPN structure to 'roperator', again to avoid a
1177 Fixed problems in Explain decoders/encoders.
1179 --- 1.0pl2 1995/12/6
1181 Memory bug in log module fixed.
1183 --- 1.0pl1 1995/12/5
1185 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1187 Bug in Explain DatabaseInfo module fixed.
1189 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1193 The shift to v1.0 signals that we now consider the *core* functionality
1194 of YAZ reasonably stable (the core being more or less equivalent to
1195 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1196 tested (Explain not at all - though that will happen soonish).
1198 Minor changes to code to support Windows port.
1200 Various minor changes after we're getting to use GRS-1 & co. more.
1202 Added Espec-1 format.
1204 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1205 of the protocol and it cannot be selected when encoding (maps into 'string'
1206 when decoding). Needed to talk to some servers.
1208 Demo client can request simple element set names.
1210 Added Diagnostic Format encoders/decoders.
1212 Added simple Close handling to frontend server (no hooks for resource
1213 reporting yet), and demonstration client.
1215 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1217 --- 1.0b3 1995/08/24
1219 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1220 handled incorrectly when records were requested in the searchResponse. This
1221 will only affect you if you use the frontend-server.
1223 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1224 Test-client will ask for and print GRS1. Ztest will return dummy records
1227 Added Explain encoders/decoders to the service-level API. Untested.
1229 Added Extended Services: Item Order encoders and decoders to the Service-
1230 level API. Untested. We could use a recent copy of the pertinent bits
1231 of the ILL protocol to add those bits.
1233 Added diagnostic format 1 encoders/decoders to the service-level API.
1236 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1237 odr_cons.c, which causes a more correct output.
1239 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1240 was always set to 0 when no records were requested in the searchRequest.
1242 * Added better external-handling. This shouldn't harm old code that
1243 *encodes* externals. It can break code that looks for a
1244 'single-ASN1-type' representation, since those types that are known
1245 are now decoded immediately. Look at the SUTRS sample code in
1246 seshigh.c and client.c. Documentation updated.
1248 Handling of structured records in bend_fetchresponse. Length -1 marks
1249 structured record, type is deduced from format field.
1251 --- 1.0b2 1995/06/27
1252 Fairly quick maintenance release to add SUTRS support.
1254 Fixed handling of SUTRS records in the demonstration client.
1256 * Added format field to the bend_fetchrequest and bend_fetchresponce
1257 structures of the backend API (frontend server). When the record is
1258 returned, the value of the format field is mapped to an OID. The
1259 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1260 of the record. The special value VAL_NONE in the bend_request means
1261 that no specific format was requested by the client. Documentation
1262 updated accordingly. Test server (ztest) will return a fixed dummy
1263 SUTRS record if your client requests SUTRS.
1265 Documentation updated accordingly.
1267 You can now set external libraries and RANLIB support in the top-level
1271 First public release.
