1 Possible compatibility problems with earlier versions marked with '*'.
3 MARC conversion can now generate ISO2709 output in another
4 character set. yaz-marcdump uses this facility if you invoke it
7 Added missing C decl macros for include/yaz/{soap.h,srw.h}, so that
8 functions from there can be used from C++.
12 Frontend server now transfers memory from decoded packages to stream
15 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
16 references to show up.
18 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
19 the ZOOM Abstract API. The older names for the same options are still
20 also supported for the benefit of old applications.
22 ZOOM-C supports "implementationId" and "implementationVersion" options
23 to go along with "implementationName". These allow the user code to
24 specify identification strings to be sent to servers.
25 Add OID for the new ExtLite attribute set.
27 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
28 as requested/supplid by Ere Maijala <ere@atp.fi>
30 For generic frontend server, reverse the order of
31 "toolkit-supplied / application-supplied" strings sent as implementationId,
32 Name and Version. Also, remove the spaces around the slash. This brings
33 the GFS in line with the behaviour of ZOOM-C on the client side.
35 Add function ZOOM_scanset_display_term.
37 yaz-client shows scan displayTerm if present.
39 Utility yaz-iconv is now installed by default along with the man page
42 Extend configure check for OpenSSL to use pkg-config where available (such
45 Incorporate patch by Morten Bogeskov which allows a Unix file socket
46 server to specify uid/gid/mask for socket using the format
47 unix:[user=uid,][group=gid,][umask=mask,]file=path
48 If file= is omitted the existing format is assumed, e.g.
50 in which case the mask is 0666 (rw for everybody).
52 Major restructure of YAZ source. All source in libyaz is in src directory.
53 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
54 util (utility programs such as ASN.1 compiler, yaz-marcdump).
56 Added man page for utility yaz-marcdump (used to be called marcdump).
57 yaz-marcdump is installed by 'make install'.
59 Fixed a memory leak in Generic Frontend Server that occurred when decoding
60 of incoming package failed.
62 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
64 Change prototype of odr_perror: add const to message string.
66 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
68 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
69 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
70 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
71 DNS lookup. There should not be any compatibility problems with this
72 assuming that blocking=1 or 0 is used.
74 Fix bad reference in UNIX comstack in function cs_addrstr.
76 Fix for compilation on AIX.
78 The generic front-end server (server/seshigh.c) now supports returning
79 Init diagnostics to the client in User-information-field, in
80 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
85 Allow any CQL relation (not just all,any,exact,scr).
87 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
88 that features the same UI.
90 Implemented command update0 in YAZ client which is equivalent to
91 update but uses old of Ext Update ASN.1.
93 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
94 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
95 Previously no OID was used for this info.
97 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
98 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
99 returns 'malformed search term' otherwise.
101 SortResponse member resultCount now set to NULL in sort handler of
104 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
107 Add three new utility functions for translating OIDs between various
108 formats -- symbolic name such as "Usmarc", minus-1-terminated int
109 arrays and dotted strings such as "1.2.840.10003.9.5.1":
110 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
111 char *oid_to_dotstring(const int *oid, char *oidbuf);
112 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
114 Reverted modifications for ES Update definition for z_IU0Update
115 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
116 is back to YAZ 2.0.2.
118 String value attributes for CCL parser.
120 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
121 which their FirstSearch server returns in Init responses, sometimes
122 carrying useful diagnostic information when Init fails. This has the
123 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
124 "z39.50/oclcui.asn", where its definition is somewhat different from
125 what OCLC document on their web-site, as required to interoperate with
128 Support for anonymous authentication in yaz-client. Use the command
131 * Fix the OID of the Index Data-local "admin" Extended Service from
132 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
133 the 1000, which indicates a locally-defined OID, was a mistake.
137 Fix CCL directive @case handling so that it affects string match for
138 both CCL keywords and qualifiers.
140 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
141 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
142 Decoder has been updated with ASN.1 changes as listed in
143 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
144 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
145 z_IUUpdate, remains unchanged.
147 ZOOM_record_get may now return a record in a specific character set.
148 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
149 "from" is the character set of record as returned by target. "to" is
150 the character set to be returned. If omitted, "to" is UTF-8.
152 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
154 New ODR utility, odr_getelement, which returns name of element for
155 which encoding/decoding failed.
157 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
158 in cases where a required element was omitted.
160 Bug fix: some MARC8 sequences were not converted.
162 New ZOOM option "step" which specifies number of records to be
163 retrieved in one chunk. Used in conjunction with "start" and "count".
165 SRW support for yaz-client. Use scheme http: to use it, e.g.
168 yaz-client no longer does (un)intelligent character set conversions
169 by default. Can be enabled with charset and marc_charset commands.
171 xmalloc trace fix for 64-bit systems such as DEC alpha.
173 Solaris 2.6 compile fix.
175 New function, cql_strerror() translates SRW error codes, as returned
176 by cql_transform_error(), into human-readable English strings. Used
177 in yaz-client diagnostics when appropriate.
179 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
180 converts it into a type-1 query which is sent to the server. This
181 makes CQL available for use with all Z-servers, as opposed to the tiny
182 minority that can handle CQL queries themselves.
186 New Debian package layout similar to the Redhat Package layout.
188 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
189 and search result respectively.
193 Redhat package is now several packages: libyaz (runtime libraries),
194 libyaz-devel (development and documentation, and yaz (utility programs).
195 Package spec file by Morten Bøgeskov.
197 New member 'schema' in struct bend_fetch_rr which the name of requested
198 schema (SRW/SRU) for record (or NULL if none was given). The fetch
199 handler MAY set this to reflect the schema of the returned record.
201 New member 'display_term' in struct scan_entry. GFS now sets member entries
202 and allocates scan entries to be filled by user scan handler. In previous
203 version, entries member was allocated by the scan handler. That still works,
204 but the GFS will ignore member display_term - assuming it was NOT set by
205 the handler. The fact that the GFS now allocates the entries both allows
206 for new members and makes a scan handler easier to write.
208 Fix CQL lex buffer overflow.
210 SRW/SRU recordPacking. For SRW default recordPacking is string. For
211 SRU default recordPacking is string.
213 SRU protocol support for frontend server.
215 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
217 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
219 Added scan for the ZOOM shell (zoomsh).
223 * String Identifers for Schemas (Amendment 5).
224 http://lcweb.loc.gov/z3950/agency/amend/am5.html
225 Old definition for schema
226 Odr_oid *schema; /* OPT */
231 Z_InternationalString *uri;
232 #define Z_Schema_oid 1
233 #define Z_Schema_uri 2
236 * resultCount parameter to Sort Response (Amendment 1).
237 http://lcweb.loc.gov/z3950/agency/amend/am1.html
239 Support for SRW 1.0 over HTTP. This is an optional feature and
240 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
243 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
244 on the same port. SRW SearchRetrieveRequests are mapped
245 to bend_init,bend_search,bend_fetch,bend_close.
247 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
249 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
250 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
252 ZOOM connections are SRW based if schem http is used for hostname
253 in connect, e.g. z = ZOOM_connection_new("http://myserver");
254 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
256 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
257 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
258 distance=n, order=true/false, relation=le, prox unit=word. If
259 n is omitted, distance 1 is used.
261 Fixed problem with C compiler include path in wrong order.
263 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
264 on Solaris. Patch from Ko van der Sloot.
266 New MARC decode API. All new functions operate on a yaz_marc_t
267 handle. The most important new functions are: yaz_marc_create,
268 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
269 decode and destroy respectively. Decoder can produce formats
270 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
271 include/yaz/marcdisp.h.
273 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
274 to UTF-8, UCS-32, wchar_t or Latin-1.
276 * Prototypes for yaz_iconv_-functions moved to separate header
277 include/yaz/yaz-iconv.h.
279 Make a few private functions 'static' in unix.c. This prevents
280 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
282 For ZOOM connection, the options targetImplementation{Id,Name,Version}
283 are set when Init Response is received.
285 New function ZOOM_connection_error_x similar to ZOOM_connection_error
286 but returns diagnostic set as well.
288 New function yaz_strerror which is a portable wrapper for
289 strerror/strerror_r/GetLastMessage.
291 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
292 is returned for MARC. If type is "oai", then OAI MARC is returned.
294 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
299 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
301 Fix bad race conditions on SIGTERM and terminate gracefully in
304 Move retrieval (data1) module to Zebra since nobody seems to be
307 Add GRS-1 render for ZOOM using same format as yaz-client.
311 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
313 Fix broken ESpec handling in data1 module.
315 SGML reader parses comments and makes them part of the data1 tree.
317 Added several type casts so that YAZ compiles as C++ code.
319 ZOOM didn't handle PDU encoding failures properly.
321 Added more Bib-1 diagnostics (approved extensions).
323 GNU configure: better check for iconv.
325 More portable use of accept, getpeername. Check for socklen_t. Use
326 int/size_t if socklen_t is not defined.
330 PQF parser rejects bad queries - including those with extra
331 characters in them. PQF parser used to silently ignore that.
332 Cleaner API for PQF added, which allows you to get detailed
333 error information for bad queries (see yaz/pquery.h).
335 Fixed bug in ZOOM_record_get for type "database".
337 Implemented mini iconv library supporting conversions between
338 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
340 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
344 Fixed ZOOM C record cache so that preferredRecordSyntax and
345 elementSetName is used to check for already fetched records.
349 Added three members in bend_initrequest structure to facilitate
350 character set negotiation.
352 Fixed a bug in frontend server that could cause indefinite
353 loops under rare conditions.
355 Revised character set utilities (charneg.h) so that encoding
356 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
358 For PQF, directive @term <type> sets term type for Scan/Search.
359 Here <type> is general, string, numeric, null. The term type
360 is inherited - just like @attr.
362 New call odr_set_charset that sets character set conversion for
363 international-strings on a ODR stream. Prototype is:
364 int odr_set_charset(ODR o, const char *to, const char *from);
365 The InternationalString is still represented as C string in YAZ
366 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
367 won't). On the protocol level, you can use any encoding.
369 Support for UNIX sockets in ZOOM.
371 Solaris recv sometimes returns errno == ENOENT. It is treated as
372 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
374 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
375 both client and server. Code by Morten Bøgeskov.
379 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
380 that they can be used directly from Visual Basic. You must recompile
381 your windows APP if you're using ZOOM.
383 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
384 Commands "lang" and "charset" sets language and character set respectively.
385 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
386 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
388 Attributes from multiple CCL fields may be OR'ed rather than merged
389 using directive "@field or". Fields are still merged by default -
390 equivalent to "@field merge".
392 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
395 Fixed bug in zget for parameter ExtendedServicesResponse.
401 Added PQF feature: '@attr type=value' may be written as '@type=value'.
403 Client displays USR.1:SearchResult-1 (hits per term).
405 Additional Search Info for search in Generic Frontend Server.
407 Fixed CCL parsing of "field=s".
409 WIN32 installer - using the excellent NSIS software from nullsoft.
411 Fixed CCL parsing of "field = - <number>".
413 Added function yaz_marc_decode that decodes MARC for line mode
414 display or XML (similar to that used by JZKit).
416 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
417 Z39.50. But ISO/ILL was, however.
419 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
420 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
422 http://lcweb.loc.gov/z3950/agency/amend/am2.html
423 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
427 New YAZ client features: Command completion and new commands:
428 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
429 Code provided by Jacob Poulsen.
431 New call oid_trav, that visits all registered OIDs via callback.
433 Function ZOOM_record_get now returns const char pointer rather than
434 void pointer. It saves a lot of type casts.
436 For YAZ client, command "auth" now allows you to set authentication
437 in IdPass style. It is enabled when three tokens are given - order
438 is user, group and password.
440 Fix memory leaks in MARC record handling for ZOOM.
442 New option for YAZ client, -k <kilobytes> that sets
443 maximum record size. Similar to -k option for generic frontend
444 server and yaz-ztest.
446 More fixes for scan. Non-zero stepSize handled. OID's fixes.
448 Prefix query parser reports "fail" when bad attribute set is given.
450 Fix in MARC decoder. Proximity logging. Fix for attribute set
451 in scan handler for server. Patches by Shigeru Ishida.
453 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
456 Configure option --with-openssl=<dir> now works when a directory is
457 specified. Patch provided by Morten Bøgeskov.
459 New option for YAZ client, -u <auth>, that sets authentication.
461 ZOOM fix: error information was sometimes "missing", since error
462 was cleared/reset too when it shouldn't.
464 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
468 Scan for ZOOM API. New object ZOOM_scanset. New functions
469 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
470 ZOOM_scanset_destroy.
472 New ZOOM function, ZOOM_connection_last_event, that returns type
473 of last event (such as "receive data", "send data", "apdu received",
476 New ZOOM option, schema, that specifies schema for retrieval.
478 New CCL feature. Qualifiers can be aliases for one or more
479 other qualifiers (if more than one is given, OR is used).
481 ZOOM uses named result sets if target supports it.
483 Two new YAZ client commands: . (dot, which sources a script of YAZ
484 client commands), and ! (to execute shell command.). Implemented
487 Working on Debian packages.
491 YAZ client enables named result sets only if target supports it.
493 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
495 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
496 with key="host" to get same result.
498 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
499 Function Z3950_resultset_record(s) returns references to records
500 "owned" by resultset. To become owner use Z3950_record_clone.
502 Function z_ext_record handles Extended Services. Thanks to
507 CCL Parser fix: ignore token comma when dealing with and-lists.
509 Documentation updates for COMSTACK.
511 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
512 Changed prototype Z3950_records. For some functions, int parameters
513 were changed to size_t.
515 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
518 New MARC decode/display function, marc_display_exl, which properly rejects
519 non-ISO2709 records. YAZ client uses it.
523 Fix bug: local attribute set wasn't set correctly in PQF strings.
527 * Old Z39.50 codecs no longer supported.
529 Added ZOOM C binding. See http://zoom.z3950.org/
531 Renamed states for COMSTACKs to avoid confusion with events.
533 Implemented cs_look and proper cs_rcvconnect.
535 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
537 Configure detects POSIX threads on OpenBSD.
539 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
540 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
542 When error is returned from present handler, non-surrogate diagnostic
543 is returned in present response (and fetch handler is no longer called).
545 * Minor adjustments to pquery parser (PQF). Token characters may be
546 escaped by using backslash (C-style).
548 PQF parser allows string attribute values to be specified. For @attr,
549 non-numeric characters after the equal-sign are treated as strings
550 (e.g. @attr 9=title).
552 CCL trunction character may be defined (@truncation in file)
554 * function zget_ExtendedServicesRequest sets waitAction to
555 waitIfPossible (was wait).
557 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
560 CCL operator names may be set in field definition files (CCL_bibset).
561 See ccl/bib1 for an example.
563 Fixes in ASN.1 compiler for C++ compatibility.
565 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
566 and "op_or" to avoid conflict with C++.
568 Fixed problem with GNU readline detection on Redhat 7.0.
570 Added step-size for Scan backend handler.
572 Fixed bug that made the frontend server crash when no attribute
573 set was specified for scan.
575 Front-end server automatically switches to original working directory
576 when installed as an NT service. Previously -w had to be specified to
579 Added extended attributes for retrieval module (data1), so that data1
580 records carry d1_readXML/SGML attributes. d1_read also supports
581 null-data rules ( <tag/>)
583 On UNIX when POSIX threads are available, a separate library libyazthread
584 is created. Programmers should link with that library and the yaz library
585 when using threads. The reason for the split was that some applications
586 on Linux, such as Apache, doesn't work well when using shared objects that
589 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
590 (or any frontend server) in SSL mode by specifying ssl: followed by
591 address. Only tested on UNIX.
593 Added feature for CCL module. Virtual structure s=al or s=ol generates
594 and-list and or-list respectively instead of phrase search.
598 * Added prefix "yaz_" for the functions log_init.., log_file.. and
599 log_mask_str. This was done to avoid name conflicts with other libraries
600 (such as other PHP extensions).
602 Added raw OID member for preferred record syntax (request_format_raw)
603 and returned record syntax (output_format_raw) for backend fetch method.
605 Config file yaz-config now accepts options so that it returns specific
606 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
608 Shared library support for UNIX using GNU libtool.
610 * Modified backend interface. Request/Response struct's replaced by
611 one read/write C struct. For example bend_fetchrequest and
612 bend_fetchresult have been replaced by single bend_fetch_rr struct.
613 Every handler - even search has to be registered in bend_init
614 handler. This means that the YAZ library no longer refers to
615 external functions and it makes it possible to make the whole
616 thing a single DLL/SO.
618 Added Segment handler for backend server.
620 Added Zmbol/Zebra administrative functions to YAZ client.
622 Threaded frontend server on UNIX (when POSIX Threads are available).
623 Starting the server with option -T enables multi-threading.
627 Added configure option --enable-comp/disable-comp to control use
628 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
629 located in sub directory asn.
631 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
632 in ${exec_prefix}/bin along with the other programs yaz-client and
635 GNU automake used to maintain makefiles.
639 Changed retrieval module so that we can load records with no abstract
640 syntax defined. Tagpaths in these records are fully composed of string
643 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
647 On UNIX, the generated makefile now supports a proper 'make install'.
648 The prefix can be set via GNU configure to set the install location
649 (default is /usr/local).
651 * YAZ programs client and ztest were renamed to yaz-client and
652 yaz-ztest to avoid conflicts when users install YAZ in "standard"
653 locations, such as /usr/bin,/usr/local/bin,etc.
655 * YAZ Header files were moved from include to include/yaz. YAZ Header
656 files are referred to as include <yaz/log.h> rather than <log.h>.
657 The YAZ include path (-I ..) is therefore the same as before. Programmers
658 should update their #include statements or use -Ipath/include/yaz
659 instead. The main motivation for doing this change is that YAZ header files
660 can be installed in "standard" locations /usr/include,/usr/local/include
661 without introducing conflicts, since ALL YAZ header files are stored
662 in subdirectory yaz (under /usr/include for example).
664 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
665 rather than project/workspace files. We switched because project files
666 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
669 Changed name of logging function, logf, to yaz_log, to prevent name
670 clash with some math-log functions. The YAZ header log.h defines logf
671 to yaz_log (#define) so there should be no incompatibilities by this
674 Added bend_start/bend_stop handlers for server. These handler are
675 called on start/stop of server. For windows they are called whenever
676 a service is started/stopped.
678 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
679 a fairly small ASN.1 compiler written in Tcl. The compiler is located
680 in util/yc.tcl. The auto-generated C code structures are, in a few
681 cases, incompatible with the old decoders. There are differences in the
682 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
683 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
684 The preprocessor variable ASN_COMPILED is defined when the compiled
685 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
686 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
687 wish to use the old encoders/decoders you can specify --disable-yc
690 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
691 version so that it supports both new - and old version of DB Update
693 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
694 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
695 change. The name parameter can be set to 0 in which no name is specified
696 for the construction. The macros odr_implicit and odr_explicit sets name
697 parameter to zero for the construction involved. New macros
698 odr_implicit_tag and odr_explicit_tag are similar to the others,
699 except that a name parameter is added. For programmers' that don't use
700 ODR they probably only need to change the call to z_APDU and z_External.
702 Added access control facility by interfacing the TCP wrapper library.
703 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
704 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
705 name of the daemon and enables the access control as specified in
706 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
708 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
709 den Dool <H.M.vdnDool@kub.nl>.
711 Added reference ID parameter to most functions in server API - refer
712 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
714 Changed name of ccl library to libccl.a (was ccl.a).
716 Fixed bug in decoder for Explain (Category TargetInfo).
718 Added support for GNU readline in client. Thanks to Jacob Poulsen
719 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
721 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
722 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
723 IMPLEMENTATION! This change was made to the development version before
724 the ZIG decided to retract the amendment. If any users MUST be
725 compatible with the original Update definition, PLEASE CONTACT US, and
726 we will include a separate definition corresponding to the old Update
727 ES. Note that because of the change to the ASN.1 of the
728 TaskPackageRecordStructure we cannot define a single structure that
729 will support both versions.
731 * Added const modifier to buffer parameter for some ODR/BER encoding
732 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
733 completeWAIS, odr_dumpBER.
735 Fixed bug in client.c which caused a crash when a scanResponse didn't
736 contain positionOfTerm.
738 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
739 * will cause an error in a client if a non-YAZ target sends both a
740 * list of Scan entries and non-surrogate diagnostics.
742 Retrieval module enhancements. Tag sets may be typed in the reference
743 to it. From the .abs-file the "tagset" directive takes a third optional
744 integer type for the tag set referenced. From a .tag-file the "include"
745 directive takes a third optional type as well. The old "type" directive
746 in the tag set itself is still recognized but acts as the default type
749 Backend interface change. Individual Scan terms returned from bend_scan
750 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
751 in include/backend.h.
753 Retrieval module enhancements. Multiple tag sets and attribute sets may
754 be specified in abstract syntax specs. Revised the error/warning for
755 logging messages reported by the retrieval module when reading the
758 Object Identifier system (oid_..) changed. The API is backwards
759 compatible but the oid-routines now allocates new OID's when needed.
760 Raw OID's may be specified in oid_getvalbyname.
762 YAZ now uses GNU configure to generate Makefile(s).
764 * Minor changes in some of the member names of DeleteResultSetRequest and
765 DeleteResultSetResponse. See include/proto.h.
767 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
768 and added member 'languages' in TargetInfo (which was missing).
770 Changed the way attribute sets are handled in the retrieval
771 module. These are now cached, just like the abstract syntaxes
774 Changed YAZ so that it links with compiled ASN.1.
776 Added Explain-schema definitions and mapping routines. The following
777 Explain categories have been implemented: AttributeDetails,
778 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
780 Fixed minor bug in Windows version of Server Library.
782 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
784 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
786 Added EXTERNAL: UNIverse Resource Report (non-standard).
788 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
789 ENUMERATED and SET OF.
791 * Added 'const' to some of the char pointer arguments for the
792 functions, data1_read_node, data1_getelementbytagname,
793 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
796 Fixed bug in data1_insert_taggeddata - the last_child member of
797 parent wasn't initialised.
799 * Changed data1_read_record and data1_read_node so that the supplied
800 "SGML"-buffer is read-only. In particular the resulting data1 - tree
801 doesn't refer to any parts of the "SGML"-buffer.
803 Fixed bug in server library (Windows version of statserv_remove).
805 * Changed code so that it compiles as C++. The type definition
806 of Odr_fun which is a member of Odr_arm was changed. The result is,
807 that an explicit typecast is needed for the fun pointer when
808 using Odr_arm - as in:
809 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
811 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
813 Implemented the new structured date and time definition as approved
814 by the ZIG. Added schemaId element to the specificTag in Espec-1
815 (also approved at the last ZIG). Thanks to RVDM.
817 Added some Object identifiers (RVDM).
819 Changed the Update Extended Service (RVDM).
821 Added command "refid" to client which specifies referenceId for
822 the following requests.
824 Implemented extended service handling for server. See ztest.c
825 for an example as well as backend.h. New handlers are registerd
828 * Changed interface for sort in server.
830 Added new members to statserv_options_block. It allows a server
831 to read options from another source than just the command line. Thanks
832 to Charles Woodfield.
834 * Changed definition of Z_Triple in file prt-grs.h - member boolean
835 renamed to zboolean. Some C++ compilers complained about the name.
837 Minor changes to gils.abs. Added index 's' (sort) on title
838 and date/time-last-modified.
842 Fixed bug in server library regarding inetd mode (-i). This bug
843 was introduced by release 1.4.
847 Added sort facility in client and backend server interface.
849 Fixed problem with dependencies in Makefile(s).
851 Fixed bugs for encoders/decoders of extended services and
854 Implemented sub-tree feature for schemas. Sub-trees are
855 referenced in *.abs-files. See explain.abs for an example
856 of the use of this feature.
858 Modified bib1.att; local attributes for ANY didn't include
859 ANY itself (only affects use of the retrieval module).
861 Fixed bug in plain SGML reader in function data1_read_node:
862 tags with prefix "var" was incorrectly interpreted as variants.
864 Added feature "sub-schemas" to enable references to - and definitions
865 of - group of elements.
867 * Removed member parent from type data1_element (in data1.h).
869 Implemented function odr_nullval() that returns the value of
872 * Removed member num_children from data1_node (in data1.h).
874 Made NT service interface part of the server library. The
875 function statserv_main uses the NT service when required and
876 calls the statserv_start / statserv_close routines.
878 Routine zget_SearchRequest and zget_PresentRequest fills
879 resultSetName/Id member with "default" instead of "Default".
881 Fixed memory leak in server. Request queue member wasn't freed.
883 Fixed nmem_exit so that memory is freed.
887 Revised the CCL parser utility to be thread safe.
889 Added function, oid_ent_to_oid, to replace the function
890 oid_getoidbyent, which is not thread safe.
892 * Added nmem_init and nmem_exit to initialize and release
893 NMEM resources. Function nmem_init should be called once in the
894 initial thread before NMEM/ODR is used. statserv.c and client.c
895 have been changed accordingly. The change was necessary to make
896 NMEM thread safe. The NMEM memory pool is shared amongst threads
897 in a process. Unix-based applications will still work fine without
900 Added NT Services interface for the the Z39.50 (statserv) Server.
901 Refer to the ztest.c source on the usage.
903 Windows 95/NT port using MSVC5.0. Project files are included in the
906 * Defined new 'global' handle for the retrieval (data1) system. The
907 new handled, data1_handle, describes the state of the data1 system.
908 This handle is passed as first argument to virtually all
909 data1 related routines. The functions data1_create and data1_destroy
910 creates and destroys a data1 handle respectively.
912 Added ODR encode stream member to all backend request structures
913 init, search, scan etc. This stream should be used to allocate all
914 memory used for the response when thread safe operation is needed.
916 Changed the comstack utility, cs_addstr, to be thread safe. The
917 returned hostname string returned by the function is now part the
920 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
921 function. The cs_straddr takes a COMSTACK handle as argument, so this
922 function must be used after cs_create and before bind/connect.
923 This function is thread safe.
925 Moved test server to 'ztest' directory - generic server code still
926 in 'server' directory.
928 Made prefix query (pquery.c) utility thread safe.
930 Added new function modifier YAZ_EXPORT to 'export' public DLL
931 functions when using windows (see include/yconfig.h).
933 Added definitions to the OID database (util/oid.c) (RVDM).
935 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
937 Added call to ccl_rpn_delete in client program.
939 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
940 release of RPN structure.
942 Added support for C++, headers uses extern "C" for public definitions.
943 With input from RVDM.
945 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
946 Thanks to Ronald van der Meer (RVDM).
948 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
950 Added support for private extensions to the OID database
951 (oid_setprivateoids()). Thanks to RVDM.
953 Added optional, physical ANY (key replication)
955 Fixed null-reference problem in GRS-1 output filter.
957 Proximity operator added to Prefix Query Format (PQF).
959 In test client command "base" accepts multiple databases.
961 Fixed bug in cs_close stack that caused trouble with WINSOCK.
965 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
967 Smallish bug-fixes in the new encoders/decoders (explain).
969 Bug fixed in DeleteRequest.
971 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
973 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
975 Added SOIF syntax (using private OID for now) to retrieval module and client.
977 Added Update extended service.
979 Added SearchResult-1 additional info structure.
981 Added optional CCL (ISO8777) interpreter as separate module. Available
984 --- 1.2 1996/6/10 (1st anniversary release)
986 Added Summary record syntax. Lightly tested.
988 Added OPAC record syntax. Untested.
990 Added ResourceReport service encoders/decoders. Untested.
992 Fixed bug in z_Unit - wrong tagging on unitSystem.
994 Fixed bug in the DiagRecs decoder.
996 Added options for max PDU size and session timeout to frontend-server.
998 Added documentation of query-language parsers and other supporting utilities.
1000 [frontend-server] Added Attribute set to the bend_scanrequest API.
1002 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1003 surrogate diagnostics were generated.
1005 [retrieval] Allow multiple local values for attribute.
1007 [retrieval] Allow multiple attributes per element in .abs files. index type.
1009 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1011 --- 1.1pl2 1996/4/10
1013 Minor changes, mostly specific to Zebra's requirements (retrieval)
1017 Repaired bug in frontend server when running multiple listening
1018 endpoints in dynamic mode.
1020 z_External() now won't break if a known, ASN.1 value comes encapsulated
1021 in an octet-string. The value will pass through unmodified in an Odr_oct.
1023 Added a bit of code to the demo client to decode & display
1024 ASN.1-structured records represented in the octet-aligned branch of
1025 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1027 Added z_ext_getentbyref() to the ASN module. Doc updated.
1029 * Completed the SCAN definition in the ASN module. This may break SCAN
1030 code based on older YAZ-versions at compile-time. The fix is easy -
1033 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1034 under the SCAN definition. Remember to initialize this, server-people.
1036 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1037 that this does not extend to ODR and ASN.
1039 Comstack allows insertion of established socket (primarily for
1040 inetd-operation of servers). Doc updated.
1042 Front-end server can now start from the inetd in TCP mode. Doc
1045 --- 1.0pl4 1996/1/24
1049 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1050 the rank and record number.
1052 Adjustments to the frontend server.
1054 Fixed diagnostic BER dumper. It ignored the file argument.
1058 Various changes to retrieval module.
1060 Changed the union discriminators of the protocol files from enums to
1061 ints paired with #defines.
1063 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1066 *Changed operator in the RPN structure to 'roperator', again to avoid a
1069 Fixed problems in Explain decoders/encoders.
1071 --- 1.0pl2 1995/12/6
1073 Memory bug in log module fixed.
1075 --- 1.0pl1 1995/12/5
1077 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1079 Bug in Explain DatabaseInfo module fixed.
1081 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1085 The shift to v1.0 signals that we now consider the *core* functionality
1086 of YAZ reasonably stable (the core being more or less equivalent to
1087 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1088 tested (Explain not at all - though that will happen soonish).
1090 Minor changes to code to support Windows port.
1092 Various minor changes after we're getting to use GRS-1 & co. more.
1094 Added Espec-1 format.
1096 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1097 of the protocol and it cannot be selected when encoding (maps into 'string'
1098 when decoding). Needed to talk to some servers.
1100 Demo client can request simple element set names.
1102 Added Diagnostic Format encoders/decoders.
1104 Added simple Close handling to frontend server (no hooks for resource
1105 reporting yet), and demonstration client.
1107 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1109 --- 1.0b3 1995/08/24
1111 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1112 handled incorrectly when records were requested in the searchResponse. This
1113 will only affect you if you use the frontend-server.
1115 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1116 Test-client will ask for and print GRS1. Ztest will return dummy records
1119 Added Explain encoders/decoders to the service-level API. Untested.
1121 Added Extended Services: Item Order encoders and decoders to the Service-
1122 level API. Untested. We could use a recent copy of the pertinent bits
1123 of the ILL protocol to add those bits.
1125 Added diagnostic format 1 encoders/decoders to the service-level API.
1128 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1129 odr_cons.c, which causes a more correct output.
1131 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1132 was always set to 0 when no records were requested in the searchRequest.
1134 * Added better external-handling. This shouldn't harm old code that
1135 *encodes* externals. It can break code that looks for a
1136 'single-ASN1-type' representation, since those types that are known
1137 are now decoded immediately. Look at the SUTRS sample code in
1138 seshigh.c and client.c. Documentation updated.
1140 Handling of structured records in bend_fetchresponse. Length -1 marks
1141 structured record, type is deduced from format field.
1143 --- 1.0b2 1995/06/27
1144 Fairly quick maintenance release to add SUTRS support.
1146 Fixed handling of SUTRS records in the demonstration client.
1148 * Added format field to the bend_fetchrequest and bend_fetchresponce
1149 structures of the backend API (frontend server). When the record is
1150 returned, the value of the format field is mapped to an OID. The
1151 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1152 of the record. The special value VAL_NONE in the bend_request means
1153 that no specific format was requested by the client. Documentation
1154 updated accordingly. Test server (ztest) will return a fixed dummy
1155 SUTRS record if your client requests SUTRS.
1157 Documentation updated accordingly.
1159 You can now set external libraries and RANLIB support in the top-level
1163 First public release.
