1 Possible compatibility problems with earlier versions marked with '*'.
3 --- 2.0.9-6 2004/01/12 Debian/Windows
5 Make the SRU server more picky WRT unknown params, etc.
7 Bug fix: ZOOM scan response didn't return displayTerm - when present.
9 New YAZ client command, options, that sets Z39.50 options.
11 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
12 options from a string of tokens (one token for each option bit).
14 Update SRW diagnostic code messages.
16 --- 2.0.9-5 2004/01/07 Debian/Windows
18 Handle user defined stylesheet for SRW/SRU.
20 --- 2.0.9-4 2004/01/06 Debian/Windows
22 Fix bug in decoding of Content-Length.
24 --- 2.0.9-3 2004/01/06 Debian/Windows
26 Fix a bug with decoding of XML packed records.
28 --- 2.0.9-2 2004/01/05 Debian only
30 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
32 Fix bug in SRW/SRU diagnostics decoding.
36 Fixed bug in Generic Frontend Server which could drop records exceeding
37 preferred message size. Reported and fixed by Irina Dijour.
39 Fixed calculation of package size for structured records in Generic
40 Frontend Server. Reported and fixed by Irina Dijour.
42 Fixed namespace for SRW/SRU diagnostics.
44 Fixed SEGV in yaz-client that occured for HTTP connection errors.
48 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
49 this version is incompatible with version 1.0 and older YAZ SRW/SRU
52 CQL changes to reflect recent changes to the specification:
53 * Documentation talks about context sets instead of index sets.
54 * Documentation talks about indexes instead of qualifiers.
55 * The CQL-to-PQF transformer's configuration file now uses
56 "index.set.name = <attributes>" instead of the old form
57 "qualifier.set.name = <attributes>". (Both forms are still
58 understood but the latter is deprecated.)
59 * CQL terms with no explicit index specified are now interpreted as
60 cql.serverChoice instead of srw.serverChoice (which of course
61 behaves exactly the same.)
65 MARC conversion can now generate ISO2709 output in another
66 character set. yaz-marcdump uses this facility if you invoke it
69 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
70 functions from there can be used from C++.
74 Frontend server now transfers memory from decoded packages to stream
77 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
78 references to show up.
80 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
81 the ZOOM Abstract API. The older names for the same options are still
82 also supported for the benefit of old applications.
84 ZOOM-C supports "implementationId" and "implementationVersion" options
85 to go along with "implementationName". These allow the user code to
86 specify identification strings to be sent to servers.
87 Add OID for the new ExtLite attribute set.
89 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
90 as requested/supplid by Ere Maijala <ere@atp.fi>
92 For generic frontend server, reverse the order of
93 "toolkit-supplied / application-supplied" strings sent as implementationId,
94 Name and Version. Also, remove the spaces around the slash. This brings
95 the GFS in line with the behaviour of ZOOM-C on the client side.
97 Add function ZOOM_scanset_display_term.
99 yaz-client shows scan displayTerm if present.
101 Utility yaz-iconv is now installed by default along with the man page
104 Extend configure check for OpenSSL to use pkg-config where available (such
107 Incorporate patch by Morten Bogeskov which allows a Unix file socket
108 server to specify uid/gid/mask for socket using the format
109 unix:[user=uid,][group=gid,][umask=mask,]file=path
110 If file= is omitted the existing format is assumed, e.g.
112 in which case the mask is 0666 (rw for everybody).
114 Major restructure of YAZ source. All source in libyaz is in src directory.
115 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
116 util (utility programs such as ASN.1 compiler, yaz-marcdump).
118 Added man page for utility yaz-marcdump (used to be called marcdump).
119 yaz-marcdump is installed by 'make install'.
121 Fixed a memory leak in Generic Frontend Server that occurred when decoding
122 of incoming package failed.
124 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
126 Change prototype of odr_perror: add const to message string.
128 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
130 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
131 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
132 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
133 DNS lookup. There should not be any compatibility problems with this
134 assuming that blocking=1 or 0 is used.
136 Fix bad reference in UNIX comstack in function cs_addrstr.
138 Fix for compilation on AIX.
140 The generic front-end server (server/seshigh.c) now supports returning
141 Init diagnostics to the client in User-information-field, in
142 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
147 Allow any CQL relation (not just all,any,exact,scr).
149 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
150 that features the same UI.
152 Implemented command update0 in YAZ client which is equivalent to
153 update but uses old of Ext Update ASN.1.
155 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
156 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
157 Previously no OID was used for this info.
159 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
160 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
161 returns 'malformed search term' otherwise.
163 SortResponse member resultCount now set to NULL in sort handler of
166 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
169 Add three new utility functions for translating OIDs between various
170 formats -- symbolic name such as "Usmarc", minus-1-terminated int
171 arrays and dotted strings such as "1.2.840.10003.9.5.1":
172 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
173 char *oid_to_dotstring(const int *oid, char *oidbuf);
174 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
176 Reverted modifications for ES Update definition for z_IU0Update
177 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
178 is back to YAZ 2.0.2.
180 String value attributes for CCL parser.
182 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
183 which their FirstSearch server returns in Init responses, sometimes
184 carrying useful diagnostic information when Init fails. This has the
185 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
186 "z39.50/oclcui.asn", where its definition is somewhat different from
187 what OCLC document on their web-site, as required to interoperate with
190 Support for anonymous authentication in yaz-client. Use the command
193 * Fix the OID of the Index Data-local "admin" Extended Service from
194 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
195 the 1000, which indicates a locally-defined OID, was a mistake.
199 Fix CCL directive @case handling so that it affects string match for
200 both CCL keywords and qualifiers.
202 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
203 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
204 Decoder has been updated with ASN.1 changes as listed in
205 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
206 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
207 z_IUUpdate, remains unchanged.
209 ZOOM_record_get may now return a record in a specific character set.
210 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
211 "from" is the character set of record as returned by target. "to" is
212 the character set to be returned. If omitted, "to" is UTF-8.
214 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
216 New ODR utility, odr_getelement, which returns name of element for
217 which encoding/decoding failed.
219 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
220 in cases where a required element was omitted.
222 Bug fix: some MARC8 sequences were not converted.
224 New ZOOM option "step" which specifies number of records to be
225 retrieved in one chunk. Used in conjunction with "start" and "count".
227 SRW support for yaz-client. Use scheme http: to use it, e.g.
230 yaz-client no longer does (un)intelligent character set conversions
231 by default. Can be enabled with charset and marc_charset commands.
233 xmalloc trace fix for 64-bit systems such as DEC alpha.
235 Solaris 2.6 compile fix.
237 New function, cql_strerror() translates SRW error codes, as returned
238 by cql_transform_error(), into human-readable English strings. Used
239 in yaz-client diagnostics when appropriate.
241 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
242 converts it into a type-1 query which is sent to the server. This
243 makes CQL available for use with all Z-servers, as opposed to the tiny
244 minority that can handle CQL queries themselves.
248 New Debian package layout similar to the Redhat Package layout.
250 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
251 and search result respectively.
255 Redhat package is now several packages: libyaz (runtime libraries),
256 libyaz-devel (development and documentation, and yaz (utility programs).
257 Package spec file by Morten Bøgeskov.
259 New member 'schema' in struct bend_fetch_rr which the name of requested
260 schema (SRW/SRU) for record (or NULL if none was given). The fetch
261 handler MAY set this to reflect the schema of the returned record.
263 New member 'display_term' in struct scan_entry. GFS now sets member entries
264 and allocates scan entries to be filled by user scan handler. In previous
265 version, entries member was allocated by the scan handler. That still works,
266 but the GFS will ignore member display_term - assuming it was NOT set by
267 the handler. The fact that the GFS now allocates the entries both allows
268 for new members and makes a scan handler easier to write.
270 Fix CQL lex buffer overflow.
272 SRW/SRU recordPacking. For SRW default recordPacking is string. For
273 SRU default recordPacking is string.
275 SRU protocol support for frontend server.
277 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
279 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
281 Added scan for the ZOOM shell (zoomsh).
285 * String Identifers for Schemas (Amendment 5).
286 http://lcweb.loc.gov/z3950/agency/amend/am5.html
287 Old definition for schema
288 Odr_oid *schema; /* OPT */
293 Z_InternationalString *uri;
294 #define Z_Schema_oid 1
295 #define Z_Schema_uri 2
298 * resultCount parameter to Sort Response (Amendment 1).
299 http://lcweb.loc.gov/z3950/agency/amend/am1.html
301 Support for SRW 1.0 over HTTP. This is an optional feature and
302 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
305 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
306 on the same port. SRW SearchRetrieveRequests are mapped
307 to bend_init,bend_search,bend_fetch,bend_close.
309 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
311 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
312 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
314 ZOOM connections are SRW based if schem http is used for hostname
315 in connect, e.g. z = ZOOM_connection_new("http://myserver");
316 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
318 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
319 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
320 distance=n, order=true/false, relation=le, prox unit=word. If
321 n is omitted, distance 1 is used.
323 Fixed problem with C compiler include path in wrong order.
325 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
326 on Solaris. Patch from Ko van der Sloot.
328 New MARC decode API. All new functions operate on a yaz_marc_t
329 handle. The most important new functions are: yaz_marc_create,
330 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
331 decode and destroy respectively. Decoder can produce formats
332 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
333 include/yaz/marcdisp.h.
335 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
336 to UTF-8, UCS-32, wchar_t or Latin-1.
338 * Prototypes for yaz_iconv_-functions moved to separate header
339 include/yaz/yaz-iconv.h.
341 Make a few private functions 'static' in unix.c. This prevents
342 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
344 For ZOOM connection, the options targetImplementation{Id,Name,Version}
345 are set when Init Response is received.
347 New function ZOOM_connection_error_x similar to ZOOM_connection_error
348 but returns diagnostic set as well.
350 New function yaz_strerror which is a portable wrapper for
351 strerror/strerror_r/GetLastMessage.
353 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
354 is returned for MARC. If type is "oai", then OAI MARC is returned.
356 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
361 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
363 Fix bad race conditions on SIGTERM and terminate gracefully in
366 Move retrieval (data1) module to Zebra since nobody seems to be
369 Add GRS-1 render for ZOOM using same format as yaz-client.
373 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
375 Fix broken ESpec handling in data1 module.
377 SGML reader parses comments and makes them part of the data1 tree.
379 Added several type casts so that YAZ compiles as C++ code.
381 ZOOM didn't handle PDU encoding failures properly.
383 Added more Bib-1 diagnostics (approved extensions).
385 GNU configure: better check for iconv.
387 More portable use of accept, getpeername. Check for socklen_t. Use
388 int/size_t if socklen_t is not defined.
392 PQF parser rejects bad queries - including those with extra
393 characters in them. PQF parser used to silently ignore that.
394 Cleaner API for PQF added, which allows you to get detailed
395 error information for bad queries (see yaz/pquery.h).
397 Fixed bug in ZOOM_record_get for type "database".
399 Implemented mini iconv library supporting conversions between
400 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
402 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
406 Fixed ZOOM C record cache so that preferredRecordSyntax and
407 elementSetName is used to check for already fetched records.
411 Added three members in bend_initrequest structure to facilitate
412 character set negotiation.
414 Fixed a bug in frontend server that could cause indefinite
415 loops under rare conditions.
417 Revised character set utilities (charneg.h) so that encoding
418 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
420 For PQF, directive @term <type> sets term type for Scan/Search.
421 Here <type> is general, string, numeric, null. The term type
422 is inherited - just like @attr.
424 New call odr_set_charset that sets character set conversion for
425 international-strings on a ODR stream. Prototype is:
426 int odr_set_charset(ODR o, const char *to, const char *from);
427 The InternationalString is still represented as C string in YAZ
428 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
429 won't). On the protocol level, you can use any encoding.
431 Support for UNIX sockets in ZOOM.
433 Solaris recv sometimes returns errno == ENOENT. It is treated as
434 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
436 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
437 both client and server. Code by Morten Bøgeskov.
441 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
442 that they can be used directly from Visual Basic. You must recompile
443 your windows APP if you're using ZOOM.
445 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
446 Commands "lang" and "charset" sets language and character set respectively.
447 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
448 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
450 Attributes from multiple CCL fields may be OR'ed rather than merged
451 using directive "@field or". Fields are still merged by default -
452 equivalent to "@field merge".
454 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
457 Fixed bug in zget for parameter ExtendedServicesResponse.
463 Added PQF feature: '@attr type=value' may be written as '@type=value'.
465 Client displays USR.1:SearchResult-1 (hits per term).
467 Additional Search Info for search in Generic Frontend Server.
469 Fixed CCL parsing of "field=s".
471 WIN32 installer - using the excellent NSIS software from nullsoft.
473 Fixed CCL parsing of "field = - <number>".
475 Added function yaz_marc_decode that decodes MARC for line mode
476 display or XML (similar to that used by JZKit).
478 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
479 Z39.50. But ISO/ILL was, however.
481 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
482 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
484 http://lcweb.loc.gov/z3950/agency/amend/am2.html
485 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
489 New YAZ client features: Command completion and new commands:
490 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
491 Code provided by Jacob Poulsen.
493 New call oid_trav, that visits all registered OIDs via callback.
495 Function ZOOM_record_get now returns const char pointer rather than
496 void pointer. It saves a lot of type casts.
498 For YAZ client, command "auth" now allows you to set authentication
499 in IdPass style. It is enabled when three tokens are given - order
500 is user, group and password.
502 Fix memory leaks in MARC record handling for ZOOM.
504 New option for YAZ client, -k <kilobytes> that sets
505 maximum record size. Similar to -k option for generic frontend
506 server and yaz-ztest.
508 More fixes for scan. Non-zero stepSize handled. OID's fixes.
510 Prefix query parser reports "fail" when bad attribute set is given.
512 Fix in MARC decoder. Proximity logging. Fix for attribute set
513 in scan handler for server. Patches by Shigeru Ishida.
515 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
518 Configure option --with-openssl=<dir> now works when a directory is
519 specified. Patch provided by Morten Bøgeskov.
521 New option for YAZ client, -u <auth>, that sets authentication.
523 ZOOM fix: error information was sometimes "missing", since error
524 was cleared/reset too when it shouldn't.
526 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
530 Scan for ZOOM API. New object ZOOM_scanset. New functions
531 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
532 ZOOM_scanset_destroy.
534 New ZOOM function, ZOOM_connection_last_event, that returns type
535 of last event (such as "receive data", "send data", "apdu received",
538 New ZOOM option, schema, that specifies schema for retrieval.
540 New CCL feature. Qualifiers can be aliases for one or more
541 other qualifiers (if more than one is given, OR is used).
543 ZOOM uses named result sets if target supports it.
545 Two new YAZ client commands: . (dot, which sources a script of YAZ
546 client commands), and ! (to execute shell command.). Implemented
549 Working on Debian packages.
553 YAZ client enables named result sets only if target supports it.
555 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
557 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
558 with key="host" to get same result.
560 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
561 Function Z3950_resultset_record(s) returns references to records
562 "owned" by resultset. To become owner use Z3950_record_clone.
564 Function z_ext_record handles Extended Services. Thanks to
569 CCL Parser fix: ignore token comma when dealing with and-lists.
571 Documentation updates for COMSTACK.
573 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
574 Changed prototype Z3950_records. For some functions, int parameters
575 were changed to size_t.
577 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
580 New MARC decode/display function, marc_display_exl, which properly rejects
581 non-ISO2709 records. YAZ client uses it.
585 Fix bug: local attribute set wasn't set correctly in PQF strings.
589 * Old Z39.50 codecs no longer supported.
591 Added ZOOM C binding. See http://zoom.z3950.org/
593 Renamed states for COMSTACKs to avoid confusion with events.
595 Implemented cs_look and proper cs_rcvconnect.
597 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
599 Configure detects POSIX threads on OpenBSD.
601 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
602 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
604 When error is returned from present handler, non-surrogate diagnostic
605 is returned in present response (and fetch handler is no longer called).
607 * Minor adjustments to pquery parser (PQF). Token characters may be
608 escaped by using backslash (C-style).
610 PQF parser allows string attribute values to be specified. For @attr,
611 non-numeric characters after the equal-sign are treated as strings
612 (e.g. @attr 9=title).
614 CCL trunction character may be defined (@truncation in file)
616 * function zget_ExtendedServicesRequest sets waitAction to
617 waitIfPossible (was wait).
619 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
622 CCL operator names may be set in field definition files (CCL_bibset).
623 See ccl/bib1 for an example.
625 Fixes in ASN.1 compiler for C++ compatibility.
627 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
628 and "op_or" to avoid conflict with C++.
630 Fixed problem with GNU readline detection on Redhat 7.0.
632 Added step-size for Scan backend handler.
634 Fixed bug that made the frontend server crash when no attribute
635 set was specified for scan.
637 Front-end server automatically switches to original working directory
638 when installed as an NT service. Previously -w had to be specified to
641 Added extended attributes for retrieval module (data1), so that data1
642 records carry d1_readXML/SGML attributes. d1_read also supports
643 null-data rules ( <tag/>)
645 On UNIX when POSIX threads are available, a separate library libyazthread
646 is created. Programmers should link with that library and the yaz library
647 when using threads. The reason for the split was that some applications
648 on Linux, such as Apache, doesn't work well when using shared objects that
651 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
652 (or any frontend server) in SSL mode by specifying ssl: followed by
653 address. Only tested on UNIX.
655 Added feature for CCL module. Virtual structure s=al or s=ol generates
656 and-list and or-list respectively instead of phrase search.
660 * Added prefix "yaz_" for the functions log_init.., log_file.. and
661 log_mask_str. This was done to avoid name conflicts with other libraries
662 (such as other PHP extensions).
664 Added raw OID member for preferred record syntax (request_format_raw)
665 and returned record syntax (output_format_raw) for backend fetch method.
667 Config file yaz-config now accepts options so that it returns specific
668 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
670 Shared library support for UNIX using GNU libtool.
672 * Modified backend interface. Request/Response struct's replaced by
673 one read/write C struct. For example bend_fetchrequest and
674 bend_fetchresult have been replaced by single bend_fetch_rr struct.
675 Every handler - even search has to be registered in bend_init
676 handler. This means that the YAZ library no longer refers to
677 external functions and it makes it possible to make the whole
678 thing a single DLL/SO.
680 Added Segment handler for backend server.
682 Added Zmbol/Zebra administrative functions to YAZ client.
684 Threaded frontend server on UNIX (when POSIX Threads are available).
685 Starting the server with option -T enables multi-threading.
689 Added configure option --enable-comp/disable-comp to control use
690 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
691 located in sub directory asn.
693 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
694 in ${exec_prefix}/bin along with the other programs yaz-client and
697 GNU automake used to maintain makefiles.
701 Changed retrieval module so that we can load records with no abstract
702 syntax defined. Tagpaths in these records are fully composed of string
705 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
709 On UNIX, the generated makefile now supports a proper 'make install'.
710 The prefix can be set via GNU configure to set the install location
711 (default is /usr/local).
713 * YAZ programs client and ztest were renamed to yaz-client and
714 yaz-ztest to avoid conflicts when users install YAZ in "standard"
715 locations, such as /usr/bin,/usr/local/bin,etc.
717 * YAZ Header files were moved from include to include/yaz. YAZ Header
718 files are referred to as include <yaz/log.h> rather than <log.h>.
719 The YAZ include path (-I ..) is therefore the same as before. Programmers
720 should update their #include statements or use -Ipath/include/yaz
721 instead. The main motivation for doing this change is that YAZ header files
722 can be installed in "standard" locations /usr/include,/usr/local/include
723 without introducing conflicts, since ALL YAZ header files are stored
724 in subdirectory yaz (under /usr/include for example).
726 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
727 rather than project/workspace files. We switched because project files
728 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
731 Changed name of logging function, logf, to yaz_log, to prevent name
732 clash with some math-log functions. The YAZ header log.h defines logf
733 to yaz_log (#define) so there should be no incompatibilities by this
736 Added bend_start/bend_stop handlers for server. These handler are
737 called on start/stop of server. For windows they are called whenever
738 a service is started/stopped.
740 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
741 a fairly small ASN.1 compiler written in Tcl. The compiler is located
742 in util/yc.tcl. The auto-generated C code structures are, in a few
743 cases, incompatible with the old decoders. There are differences in the
744 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
745 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
746 The preprocessor variable ASN_COMPILED is defined when the compiled
747 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
748 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
749 wish to use the old encoders/decoders you can specify --disable-yc
752 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
753 version so that it supports both new - and old version of DB Update
755 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
756 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
757 change. The name parameter can be set to 0 in which no name is specified
758 for the construction. The macros odr_implicit and odr_explicit sets name
759 parameter to zero for the construction involved. New macros
760 odr_implicit_tag and odr_explicit_tag are similar to the others,
761 except that a name parameter is added. For programmers' that don't use
762 ODR they probably only need to change the call to z_APDU and z_External.
764 Added access control facility by interfacing the TCP wrapper library.
765 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
766 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
767 name of the daemon and enables the access control as specified in
768 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
770 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
771 den Dool <H.M.vdnDool@kub.nl>.
773 Added reference ID parameter to most functions in server API - refer
774 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
776 Changed name of ccl library to libccl.a (was ccl.a).
778 Fixed bug in decoder for Explain (Category TargetInfo).
780 Added support for GNU readline in client. Thanks to Jacob Poulsen
781 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
783 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
784 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
785 IMPLEMENTATION! This change was made to the development version before
786 the ZIG decided to retract the amendment. If any users MUST be
787 compatible with the original Update definition, PLEASE CONTACT US, and
788 we will include a separate definition corresponding to the old Update
789 ES. Note that because of the change to the ASN.1 of the
790 TaskPackageRecordStructure we cannot define a single structure that
791 will support both versions.
793 * Added const modifier to buffer parameter for some ODR/BER encoding
794 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
795 completeWAIS, odr_dumpBER.
797 Fixed bug in client.c which caused a crash when a scanResponse didn't
798 contain positionOfTerm.
800 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
801 * will cause an error in a client if a non-YAZ target sends both a
802 * list of Scan entries and non-surrogate diagnostics.
804 Retrieval module enhancements. Tag sets may be typed in the reference
805 to it. From the .abs-file the "tagset" directive takes a third optional
806 integer type for the tag set referenced. From a .tag-file the "include"
807 directive takes a third optional type as well. The old "type" directive
808 in the tag set itself is still recognized but acts as the default type
811 Backend interface change. Individual Scan terms returned from bend_scan
812 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
813 in include/backend.h.
815 Retrieval module enhancements. Multiple tag sets and attribute sets may
816 be specified in abstract syntax specs. Revised the error/warning for
817 logging messages reported by the retrieval module when reading the
820 Object Identifier system (oid_..) changed. The API is backwards
821 compatible but the oid-routines now allocates new OID's when needed.
822 Raw OID's may be specified in oid_getvalbyname.
824 YAZ now uses GNU configure to generate Makefile(s).
826 * Minor changes in some of the member names of DeleteResultSetRequest and
827 DeleteResultSetResponse. See include/proto.h.
829 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
830 and added member 'languages' in TargetInfo (which was missing).
832 Changed the way attribute sets are handled in the retrieval
833 module. These are now cached, just like the abstract syntaxes
836 Changed YAZ so that it links with compiled ASN.1.
838 Added Explain-schema definitions and mapping routines. The following
839 Explain categories have been implemented: AttributeDetails,
840 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
842 Fixed minor bug in Windows version of Server Library.
844 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
846 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
848 Added EXTERNAL: UNIverse Resource Report (non-standard).
850 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
851 ENUMERATED and SET OF.
853 * Added 'const' to some of the char pointer arguments for the
854 functions, data1_read_node, data1_getelementbytagname,
855 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
858 Fixed bug in data1_insert_taggeddata - the last_child member of
859 parent wasn't initialised.
861 * Changed data1_read_record and data1_read_node so that the supplied
862 "SGML"-buffer is read-only. In particular the resulting data1 - tree
863 doesn't refer to any parts of the "SGML"-buffer.
865 Fixed bug in server library (Windows version of statserv_remove).
867 * Changed code so that it compiles as C++. The type definition
868 of Odr_fun which is a member of Odr_arm was changed. The result is,
869 that an explicit typecast is needed for the fun pointer when
870 using Odr_arm - as in:
871 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
873 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
875 Implemented the new structured date and time definition as approved
876 by the ZIG. Added schemaId element to the specificTag in Espec-1
877 (also approved at the last ZIG). Thanks to RVDM.
879 Added some Object identifiers (RVDM).
881 Changed the Update Extended Service (RVDM).
883 Added command "refid" to client which specifies referenceId for
884 the following requests.
886 Implemented extended service handling for server. See ztest.c
887 for an example as well as backend.h. New handlers are registerd
890 * Changed interface for sort in server.
892 Added new members to statserv_options_block. It allows a server
893 to read options from another source than just the command line. Thanks
894 to Charles Woodfield.
896 * Changed definition of Z_Triple in file prt-grs.h - member boolean
897 renamed to zboolean. Some C++ compilers complained about the name.
899 Minor changes to gils.abs. Added index 's' (sort) on title
900 and date/time-last-modified.
904 Fixed bug in server library regarding inetd mode (-i). This bug
905 was introduced by release 1.4.
909 Added sort facility in client and backend server interface.
911 Fixed problem with dependencies in Makefile(s).
913 Fixed bugs for encoders/decoders of extended services and
916 Implemented sub-tree feature for schemas. Sub-trees are
917 referenced in *.abs-files. See explain.abs for an example
918 of the use of this feature.
920 Modified bib1.att; local attributes for ANY didn't include
921 ANY itself (only affects use of the retrieval module).
923 Fixed bug in plain SGML reader in function data1_read_node:
924 tags with prefix "var" was incorrectly interpreted as variants.
926 Added feature "sub-schemas" to enable references to - and definitions
927 of - group of elements.
929 * Removed member parent from type data1_element (in data1.h).
931 Implemented function odr_nullval() that returns the value of
934 * Removed member num_children from data1_node (in data1.h).
936 Made NT service interface part of the server library. The
937 function statserv_main uses the NT service when required and
938 calls the statserv_start / statserv_close routines.
940 Routine zget_SearchRequest and zget_PresentRequest fills
941 resultSetName/Id member with "default" instead of "Default".
943 Fixed memory leak in server. Request queue member wasn't freed.
945 Fixed nmem_exit so that memory is freed.
949 Revised the CCL parser utility to be thread safe.
951 Added function, oid_ent_to_oid, to replace the function
952 oid_getoidbyent, which is not thread safe.
954 * Added nmem_init and nmem_exit to initialize and release
955 NMEM resources. Function nmem_init should be called once in the
956 initial thread before NMEM/ODR is used. statserv.c and client.c
957 have been changed accordingly. The change was necessary to make
958 NMEM thread safe. The NMEM memory pool is shared amongst threads
959 in a process. Unix-based applications will still work fine without
962 Added NT Services interface for the the Z39.50 (statserv) Server.
963 Refer to the ztest.c source on the usage.
965 Windows 95/NT port using MSVC5.0. Project files are included in the
968 * Defined new 'global' handle for the retrieval (data1) system. The
969 new handled, data1_handle, describes the state of the data1 system.
970 This handle is passed as first argument to virtually all
971 data1 related routines. The functions data1_create and data1_destroy
972 creates and destroys a data1 handle respectively.
974 Added ODR encode stream member to all backend request structures
975 init, search, scan etc. This stream should be used to allocate all
976 memory used for the response when thread safe operation is needed.
978 Changed the comstack utility, cs_addstr, to be thread safe. The
979 returned hostname string returned by the function is now part the
982 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
983 function. The cs_straddr takes a COMSTACK handle as argument, so this
984 function must be used after cs_create and before bind/connect.
985 This function is thread safe.
987 Moved test server to 'ztest' directory - generic server code still
988 in 'server' directory.
990 Made prefix query (pquery.c) utility thread safe.
992 Added new function modifier YAZ_EXPORT to 'export' public DLL
993 functions when using windows (see include/yconfig.h).
995 Added definitions to the OID database (util/oid.c) (RVDM).
997 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
999 Added call to ccl_rpn_delete in client program.
1001 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1002 release of RPN structure.
1004 Added support for C++, headers uses extern "C" for public definitions.
1005 With input from RVDM.
1007 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1008 Thanks to Ronald van der Meer (RVDM).
1010 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1012 Added support for private extensions to the OID database
1013 (oid_setprivateoids()). Thanks to RVDM.
1015 Added optional, physical ANY (key replication)
1017 Fixed null-reference problem in GRS-1 output filter.
1019 Proximity operator added to Prefix Query Format (PQF).
1021 In test client command "base" accepts multiple databases.
1023 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1027 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1029 Smallish bug-fixes in the new encoders/decoders (explain).
1031 Bug fixed in DeleteRequest.
1033 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1035 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1037 Added SOIF syntax (using private OID for now) to retrieval module and client.
1039 Added Update extended service.
1041 Added SearchResult-1 additional info structure.
1043 Added optional CCL (ISO8777) interpreter as separate module. Available
1046 --- 1.2 1996/6/10 (1st anniversary release)
1048 Added Summary record syntax. Lightly tested.
1050 Added OPAC record syntax. Untested.
1052 Added ResourceReport service encoders/decoders. Untested.
1054 Fixed bug in z_Unit - wrong tagging on unitSystem.
1056 Fixed bug in the DiagRecs decoder.
1058 Added options for max PDU size and session timeout to frontend-server.
1060 Added documentation of query-language parsers and other supporting utilities.
1062 [frontend-server] Added Attribute set to the bend_scanrequest API.
1064 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1065 surrogate diagnostics were generated.
1067 [retrieval] Allow multiple local values for attribute.
1069 [retrieval] Allow multiple attributes per element in .abs files. index type.
1071 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1073 --- 1.1pl2 1996/4/10
1075 Minor changes, mostly specific to Zebra's requirements (retrieval)
1079 Repaired bug in frontend server when running multiple listening
1080 endpoints in dynamic mode.
1082 z_External() now won't break if a known, ASN.1 value comes encapsulated
1083 in an octet-string. The value will pass through unmodified in an Odr_oct.
1085 Added a bit of code to the demo client to decode & display
1086 ASN.1-structured records represented in the octet-aligned branch of
1087 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1089 Added z_ext_getentbyref() to the ASN module. Doc updated.
1091 * Completed the SCAN definition in the ASN module. This may break SCAN
1092 code based on older YAZ-versions at compile-time. The fix is easy -
1095 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1096 under the SCAN definition. Remember to initialize this, server-people.
1098 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1099 that this does not extend to ODR and ASN.
1101 Comstack allows insertion of established socket (primarily for
1102 inetd-operation of servers). Doc updated.
1104 Front-end server can now start from the inetd in TCP mode. Doc
1107 --- 1.0pl4 1996/1/24
1111 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1112 the rank and record number.
1114 Adjustments to the frontend server.
1116 Fixed diagnostic BER dumper. It ignored the file argument.
1120 Various changes to retrieval module.
1122 Changed the union discriminators of the protocol files from enums to
1123 ints paired with #defines.
1125 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1128 *Changed operator in the RPN structure to 'roperator', again to avoid a
1131 Fixed problems in Explain decoders/encoders.
1133 --- 1.0pl2 1995/12/6
1135 Memory bug in log module fixed.
1137 --- 1.0pl1 1995/12/5
1139 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1141 Bug in Explain DatabaseInfo module fixed.
1143 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1147 The shift to v1.0 signals that we now consider the *core* functionality
1148 of YAZ reasonably stable (the core being more or less equivalent to
1149 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1150 tested (Explain not at all - though that will happen soonish).
1152 Minor changes to code to support Windows port.
1154 Various minor changes after we're getting to use GRS-1 & co. more.
1156 Added Espec-1 format.
1158 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1159 of the protocol and it cannot be selected when encoding (maps into 'string'
1160 when decoding). Needed to talk to some servers.
1162 Demo client can request simple element set names.
1164 Added Diagnostic Format encoders/decoders.
1166 Added simple Close handling to frontend server (no hooks for resource
1167 reporting yet), and demonstration client.
1169 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1171 --- 1.0b3 1995/08/24
1173 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1174 handled incorrectly when records were requested in the searchResponse. This
1175 will only affect you if you use the frontend-server.
1177 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1178 Test-client will ask for and print GRS1. Ztest will return dummy records
1181 Added Explain encoders/decoders to the service-level API. Untested.
1183 Added Extended Services: Item Order encoders and decoders to the Service-
1184 level API. Untested. We could use a recent copy of the pertinent bits
1185 of the ILL protocol to add those bits.
1187 Added diagnostic format 1 encoders/decoders to the service-level API.
1190 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1191 odr_cons.c, which causes a more correct output.
1193 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1194 was always set to 0 when no records were requested in the searchRequest.
1196 * Added better external-handling. This shouldn't harm old code that
1197 *encodes* externals. It can break code that looks for a
1198 'single-ASN1-type' representation, since those types that are known
1199 are now decoded immediately. Look at the SUTRS sample code in
1200 seshigh.c and client.c. Documentation updated.
1202 Handling of structured records in bend_fetchresponse. Length -1 marks
1203 structured record, type is deduced from format field.
1205 --- 1.0b2 1995/06/27
1206 Fairly quick maintenance release to add SUTRS support.
1208 Fixed handling of SUTRS records in the demonstration client.
1210 * Added format field to the bend_fetchrequest and bend_fetchresponce
1211 structures of the backend API (frontend server). When the record is
1212 returned, the value of the format field is mapped to an OID. The
1213 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1214 of the record. The special value VAL_NONE in the bend_request means
1215 that no specific format was requested by the client. Documentation
1216 updated accordingly. Test server (ztest) will return a fixed dummy
1217 SUTRS record if your client requests SUTRS.
1219 Documentation updated accordingly.
1221 You can now set external libraries and RANLIB support in the top-level
1225 First public release.
