1 Possible compatibility problems with earlier versions marked with '*'.
3 Implemented mini iconv library supporting conversions between
4 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
6 Removed XML reader (d1_expat.c). It's part of Zebra instead.
10 Fixed ZOOM C record cache so that preferredRecordSyntax and
11 elementSetName is used to check for already fetched records.
15 Added three members in bend_initrequest structure to facilitate
16 character set negotiation.
18 Fixed a bug in frontend server that could cause indefinite
19 loops under rare conditions.
21 Revised character set utilities (charneg.h) so that encoding
22 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
24 For PQF, directive @term <type> sets term type for Scan/Search.
25 Here <type> is general, string, numeric, null. The term type
26 is inherited - just like @attr.
28 New call odr_set_charset that sets character set conversion for
29 international-strings on a ODR stream. Prototype is:
30 int odr_set_charset(ODR o, const char *to, const char *from);
31 The InternationalString is still represented as C string in YAZ
32 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
33 won't). On the protocol level, you can use any encoding.
35 Support for UNIX sockets in ZOOM.
37 Solaris recv sometimes returns errno == ENOENT. It is treated as
38 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
40 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
41 both client and server. Code by Morten Bøgeskov.
45 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
46 that they can be used directly from Visual Basic. You must recompile
47 your windows APP if you're using ZOOM.
49 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
50 Commands "lang" and "charset" sets language and character set respectively.
51 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
52 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
54 Attributes from multiple CCL fields may be OR'ed rather than merged
55 using directive "@field or". Fields are still merged by default -
56 equivalent to "@field merge".
58 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
61 Fixed bug in zget for parameter ExtendedServicesResponse.
67 Added PQF feature: '@attr type=value' may be written as '@type=value'.
69 Client displays USR.1:SearchResult-1 (hits per term).
71 Additional Search Info for search in Generic Frontend Server.
73 Fixed CCL parsing of "field=s".
75 WIN32 installer - using the excellent NSIS software from nullsoft.
77 Fixed CCL parsing of "field = - <number>".
79 Added function yaz_marc_decode that decodes MARC for line mode
80 display or XML (similar to that used by JZKit).
82 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
83 Z39.50. But ISO/ILL was, however.
85 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
86 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
88 http://lcweb.loc.gov/z3950/agency/amend/am2.html
89 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
93 New YAZ client features: Command completion and new commands:
94 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
95 Code provided by Jacob Poulsen.
97 New call oid_trav, that visits all registered OIDs via callback.
99 Function ZOOM_record_get now returns const char pointer rather than
100 void pointer. It saves a lot of type casts.
102 For YAZ client, command "auth" now allows you to set authentication
103 in IdPass style. It is enabled when three tokens are given - order
104 is user, group and password.
106 Fix memory leaks in MARC record handling for ZOOM.
108 New option for YAZ client, -k <kilobytes> that sets
109 maximum record size. Similar to -k option for generic frontend
110 server and yaz-ztest.
112 More fixes for scan. Non-zero stepSize handled. OID's fixes.
114 Prefix query parser reports "fail" when bad attribute set is given.
116 Fix in MARC decoder. Proximity logging. Fix for attribute set
117 in scan handler for server. Patches by Shigeru Ishida.
119 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
122 Configure option --with-openssl=<dir> now works when a directory is
123 specified. Patch provided by Morten Bøgeskov.
125 New option for YAZ client, -u <auth>, that sets authentication.
127 ZOOM fix: error information was sometimes "missing", since error
128 was cleared/reset too when it shouldn't.
130 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
134 Scan for ZOOM API. New object ZOOM_scanset. New functions
135 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
136 ZOOM_scanset_destroy.
138 New ZOOM function, ZOOM_connection_last_event, that returns type
139 of last event (such as "receive data", "send data", "apdu received",
142 New ZOOM option, schema, that specifies shema OID for retrieval.
144 New CCL feature. Qualifiers can be aliases for one or more
145 other qualifiers (if more than one is given, OR is used).
147 ZOOM uses named result sets if target supports it.
149 Two new YAZ client commands: . (dot, which sources a script of YAZ
150 client commands), and ! (to execute shell command.). Implemented
153 Working on Debian packages.
157 YAZ client enables named result sets only if target supports it.
159 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
161 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
162 with key="host" to get same result.
164 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
165 Function Z3950_resultset_record(s) returns references to records
166 "owned" by resultset. To become owner use Z3950_record_clone.
168 Function z_ext_record handles Extended Services. Thanks to
173 CCL Parser fix: ignore token comma when dealing with and-lists.
175 Documentation updates for COMSTACK.
177 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
178 Changed prototype Z3950_records. For some functions, int parameters
179 were changed to size_t.
181 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
184 New MARC decode/display function, marc_display_exl, which properly rejects
185 non-ISO2709 records. YAZ client uses it.
189 Fix bug: local attribute set wasn't set correctly in PQF strings.
193 * Old Z39.50 codecs no longer supported.
195 Added ZOOM C binding. See http://zoom.z3950.org/
197 Renamed states for COMSTACKs to avoid confusion with events.
199 Implemented cs_look and proper cs_rcvconnect.
201 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
203 Configure detects POSIX threads on OpenBSD.
205 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
206 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
208 When error is returned from present handler, non-surrogate diagnostic
209 is returned in present response (and fetch handler is no longer called).
211 * Minor adjustments to pquery parser (PQF). Token characters may be
212 escaped by using backslash (C-style).
214 PQF parser allows string attribute values to be specified. For @attr,
215 non-numeric characters after the equal-sign are treated as strings
216 (e.g. @attr 9=title).
218 CCL trunction character may be defined (@truncation in file)
220 * function zget_ExtendedServicesRequest sets waitAction to
221 waitIfPossible (was wait).
223 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
226 CCL operator names may be set in field definition files (CCL_bibset).
227 See ccl/bib1 for an example.
229 Fixes in ASN.1 compiler for C++ compatibility.
231 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
232 and "op_or" to avoid conflict with C++.
234 Fixed problem with GNU readline detection on Redhat 7.0.
236 Added step-size for Scan backend handler.
238 Fixed bug that made the frontend server crash when no attribute
239 set was specified for scan.
241 Front-end server automatically switches to original working directory
242 when installed as an NT service. Previously -w had to be specified to
245 Added extended attributes for retrieval module (data1), so that data1
246 records carry d1_readXML/SGML attributes. d1_read also supports
247 null-data rules ( <tag/>)
249 On UNIX when POSIX threads are available, a separate library libyazthread
250 is created. Programmers should link with that library and the yaz library
251 when using threads. The reason for the split was that some applications
252 on Linux, such as Apache, doesn't work well when using shared objects that
255 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
256 (or any frontend server) in SSL mode by specifying ssl: followed by
257 address. Only tested on UNIX.
259 Added feature for CCL module. Virtual structure s=al or s=ol generates
260 and-list and or-list respectively instead of phrase search.
264 * Added prefix "yaz_" for the functions log_init.., log_file.. and
265 log_mask_str. This was done to avoid name conflicts with other libraries
266 (such as other PHP extensions).
268 Added raw OID member for preferred record syntax (request_format_raw)
269 and returned record syntax (output_format_raw) for backend fetch method.
271 Config file yaz-config now accepts options so that it returns specific
272 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
274 Shared library support for UNIX using GNU libtool.
276 * Modified backend interface. Request/Response struct's replaced by
277 one read/write C struct. For example bend_fetchrequest and
278 bend_fetchresult have been replaced by single bend_fetch_rr struct.
279 Every handler - even search has to be registered in bend_init
280 handler. This means that the YAZ library no longer refers to
281 external functions and it makes it possible to make the whole
282 thing a single DLL/SO.
284 Added Segment handler for backend server.
286 Added Zmbol/Zebra administrative functions to YAZ client.
288 Threaded frontend server on UNIX (when POSIX Threads are available).
289 Starting the server with option -T enables multi-threading.
293 Added configure option --enable-comp/disable-comp to control use
294 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
295 located in sub directory asn.
297 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
298 in ${exec_prefix}/bin along with the other programs yaz-client and
301 GNU automake used to maintain makefiles.
305 Changed retrieval module so that we can load records with no abstract
306 syntax defined. Tagpaths in these records are fully composed of string
309 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
313 On UNIX, the generated makefile now supports a proper 'make install'.
314 The prefix can be set via GNU configure to set the install location
315 (default is /usr/local).
317 * YAZ programs client and ztest were renamed to yaz-client and
318 yaz-ztest to avoid conflicts when users install YAZ in "standard"
319 locations, such as /usr/bin,/usr/local/bin,etc.
321 * YAZ Header files were moved from include to include/yaz. YAZ Header
322 files are referred to as include <yaz/log.h> rather than <log.h>.
323 The YAZ include path (-I ..) is therefore the same as before. Programmers
324 should update their #include statements or use -Ipath/include/yaz
325 instead. The main motivation for doing this change is that YAZ header files
326 can be installed in "standard" locations /usr/include,/usr/local/include
327 without introducing conflicts, since ALL YAZ header files are stored
328 in subdirectory yaz (under /usr/include for example).
330 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
331 rather than project/workspace files. We switched because project files
332 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
335 Changed name of logging function, logf, to yaz_log, to prevent name
336 clash with some math-log functions. The YAZ header log.h defines logf
337 to yaz_log (#define) so there should be no incompatibilities by this
340 Added bend_start/bend_stop handlers for server. These handler are
341 called on start/stop of server. For windows they are called whenever
342 a service is started/stopped.
344 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
345 a fairly small ASN.1 compiler written in Tcl. The compiler is located
346 in util/yc.tcl. The auto-generated C code structures are, in a few
347 cases, incompatible with the old decoders. There are differences in the
348 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
349 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
350 The preprocessor variable ASN_COMPILED is defined when the compiled
351 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
352 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
353 wish to use the old encoders/decoders you can specify --disable-yc
356 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
357 version so that it supports both new - and old version of DB Update
359 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
360 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
361 change. The name parameter can be set to 0 in which no name is specified
362 for the construction. The macros odr_implicit and odr_explicit sets name
363 parameter to zero for the construction involved. New macros
364 odr_implicit_tag and odr_explicit_tag are similar to the others,
365 except that a name parameter is added. For programmers' that don't use
366 ODR they probably only need to change the call to z_APDU and z_External.
368 Added access control facility by interfacing the TCP wrapper library.
369 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
370 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
371 name of the daemon and enables the access control as specified in
372 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
374 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
375 den Dool <H.M.vdnDool@kub.nl>.
377 Added reference ID parameter to most functions in server API - refer
378 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
380 Changed name of ccl library to libccl.a (was ccl.a).
382 Fixed bug in decoder for Explain (Category TargetInfo).
384 Added support for GNU readline in client. Thanks to Jacob Poulsen
385 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
387 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
388 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
389 IMPLEMENTATION! This change was made to the development version before
390 the ZIG decided to retract the amendment. If any users MUST be
391 compatible with the original Update definition, PLEASE CONTACT US, and
392 we will include a separate definition corresponding to the old Update
393 ES. Note that because of the change to the ASN.1 of the
394 TaskPackageRecordStructure we cannot define a single structure that
395 will support both versions.
397 * Added const modifier to buffer parameter for some ODR/BER encoding
398 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
399 completeWAIS, odr_dumpBER.
401 Fixed bug in client.c which caused a crash when a scanResponse didn't
402 contain positionOfTerm.
404 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
405 * will cause an error in a client if a non-YAZ target sends both a
406 * list of Scan entries and non-surrogate diagnostics.
408 Retrieval module enhancements. Tag sets may be typed in the reference
409 to it. From the .abs-file the "tagset" directive takes a third optional
410 integer type for the tag set referenced. From a .tag-file the "include"
411 directive takes a third optional type as well. The old "type" directive
412 in the tag set itself is still recognized but acts as the default type
415 Backend interface change. Individual Scan terms returned from bend_scan
416 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
417 in include/backend.h.
419 Retrieval module enhancements. Multiple tag sets and attribute sets may
420 be specified in abstract syntax specs. Revised the error/warning for
421 logging messages reported by the retrieval module when reading the
424 Object Identifier system (oid_..) changed. The API is backwards
425 compatible but the oid-routines now allocates new OID's when needed.
426 Raw OID's may be specified in oid_getvalbyname.
428 YAZ now uses GNU configure to generate Makefile(s).
430 * Minor changes in some of the member names of DeleteResultSetRequest and
431 DeleteResultSetResponse. See include/proto.h.
433 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
434 and added member 'languages' in TargetInfo (which was missing).
436 Changed the way attribute sets are handled in the retrieval
437 module. These are now cached, just like the abstract syntaxes
440 Changed YAZ so that it links with compiled ASN.1.
442 Added Explain-schema definitions and mapping routines. The following
443 Explain categories have been implemented: AttributeDetails,
444 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
446 Fixed minor bug in Windows version of Server Library.
448 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
450 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
452 Added EXTERNAL: UNIverse Resource Report (non-standard).
454 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
455 ENUMERATED and SET OF.
457 * Added 'const' to some of the char pointer arguments for the
458 functions, data1_read_node, data1_getelementbytagname,
459 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
462 Fixed bug in data1_insert_taggeddata - the last_child member of
463 parent wasn't initialised.
465 * Changed data1_read_record and data1_read_node so that the supplied
466 "SGML"-buffer is read-only. In particular the resulting data1 - tree
467 doesn't refer to any parts of the "SGML"-buffer.
469 Fixed bug in server library (Windows version of statserv_remove).
471 * Changed code so that it compiles as C++. The type definition
472 of Odr_fun which is a member of Odr_arm was changed. The result is,
473 that an explicit typecast is needed for the fun pointer when
474 using Odr_arm - as in:
475 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
477 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
479 Implemented the new structured date and time definition as approved
480 by the ZIG. Added schemaId element to the specificTag in Espec-1
481 (also approved at the last ZIG). Thanks to RVDM.
483 Added some Object identifiers (RVDM).
485 Changed the Update Extended Service (RVDM).
487 Added command "refid" to client which specifies referenceId for
488 the following requests.
490 Implemented extended service handling for server. See ztest.c
491 for an example as well as backend.h. New handlers are registerd
494 * Changed interface for sort in server.
496 Added new members to statserv_options_block. It allows a server
497 to read options from another source than just the command line. Thanks
498 to Charles Woodfield.
500 * Changed definition of Z_Triple in file prt-grs.h - member boolean
501 renamed to zboolean. Some C++ compilers complained about the name.
503 Minor changes to gils.abs. Added index 's' (sort) on title
504 and date/time-last-modified.
508 Fixed bug in server library regarding inetd mode (-i). This bug
509 was introduced by release 1.4.
513 Added sort facility in client and backend server interface.
515 Fixed problem with dependencies in Makefile(s).
517 Fixed bugs for encoders/decoders of extended services and
520 Implemented sub-tree feature for schemas. Sub-trees are
521 referenced in *.abs-files. See explain.abs for an example
522 of the use of this feature.
524 Modified bib1.att; local attributes for ANY didn't include
525 ANY itself (only affects use of the retrieval module).
527 Fixed bug in plain SGML reader in function data1_read_node:
528 tags with prefix "var" was incorrectly interpreted as variants.
530 Added feature "sub-schemas" to enable references to - and definitions
531 of - group of elements.
533 * Removed member parent from type data1_element (in data1.h).
535 Implemented function odr_nullval() that returns the value of
538 * Removed member num_children from data1_node (in data1.h).
540 Made NT service interface part of the server library. The
541 function statserv_main uses the NT service when required and
542 calls the statserv_start / statserv_close routines.
544 Routine zget_SearchRequest and zget_PresentRequest fills
545 resultSetName/Id member with "default" instead of "Default".
547 Fixed memory leak in server. Request queue member wasn't freed.
549 Fixed nmem_exit so that memory is freed.
553 Revised the CCL parser utility to be thread safe.
555 Added function, oid_ent_to_oid, to replace the function
556 oid_getoidbyent, which is not thread safe.
558 * Added nmem_init and nmem_exit to initialize and release
559 NMEM resources. Function nmem_init should be called once in the
560 initial thread before NMEM/ODR is used. statserv.c and client.c
561 have been changed accordingly. The change was necessary to make
562 NMEM thread safe. The NMEM memory pool is shared amongst threads
563 in a process. Unix-based applications will still work fine without
566 Added NT Services interface for the the Z39.50 (statserv) Server.
567 Refer to the ztest.c source on the usage.
569 Windows 95/NT port using MSVC5.0. Project files are included in the
572 * Defined new 'global' handle for the retrieval (data1) system. The
573 new handled, data1_handle, describes the state of the data1 system.
574 This handle is passed as first argument to virtually all
575 data1 related routines. The functions data1_create and data1_destroy
576 creates and destroys a data1 handle respectively.
578 Added ODR encode stream member to all backend request structures
579 init, search, scan etc. This stream should be used to allocate all
580 memory used for the response when thread safe operation is needed.
582 Changed the comstack utility, cs_addstr, to be thread safe. The
583 returned hostname string returned by the function is now part the
586 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
587 function. The cs_straddr takes a COMSTACK handle as argument, so this
588 function must be used after cs_create and before bind/connect.
589 This function is thread safe.
591 Moved test server to 'ztest' directory - generic server code still
592 in 'server' directory.
594 Made prefix query (pquery.c) utility thread safe.
596 Added new function modifier YAZ_EXPORT to 'export' public DLL
597 functions when using windows (see include/yconfig.h).
599 Added definitions to the OID database (util/oid.c) (RVDM).
601 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
603 Added call to ccl_rpn_delete in client program.
605 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
606 release of RPN structure.
608 Added support for C++, headers uses extern "C" for public definitions.
609 With input from RVDM.
611 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
612 Thanks to Ronald van der Meer (RVDM).
614 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
616 Added support for private extensions to the OID database
617 (oid_setprivateoids()). Thanks to RVDM.
619 Added optional, physical ANY (key replication)
621 Fixed null-reference problem in GRS-1 output filter.
623 Proximity operator added to Prefix Query Format (PQF).
625 In test client command "base" accepts multiple databases.
627 Fixed bug in cs_close stack that caused trouble with WINSOCK.
631 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
633 Smallish bug-fixes in the new encoders/decoders (explain).
635 Bug fixed in DeleteRequest.
637 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
639 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
641 Added SOIF syntax (using private OID for now) to retrieval module and client.
643 Added Update extended service.
645 Added SearchResult-1 additional info structure.
647 Added optional CCL (ISO8777) interpreter as separate module. Available
650 --- 1.2 1996/6/10 (1st anniversary release)
652 Added Summary record syntax. Lightly tested.
654 Added OPAC record syntax. Untested.
656 Added ResourceReport service encoders/decoders. Untested.
658 Fixed bug in z_Unit - wrong tagging on unitSystem.
660 Fixed bug in the DiagRecs decoder.
662 Added options for max PDU size and session timeout to frontend-server.
664 Added documentation of query-language parsers and other supporting utilities.
666 [frontend-server] Added Attribute set to the bend_scanrequest API.
668 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
669 surrogate diagnostics were generated.
671 [retrieval] Allow multiple local values for attribute.
673 [retrieval] Allow multiple attributes per element in .abs files. index type.
675 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
679 Minor changes, mostly specific to Zebra's requirements (retrieval)
683 Repaired bug in frontend server when running multiple listening
684 endpoints in dynamic mode.
686 z_External() now won't break if a known, ASN.1 value comes encapsulated
687 in an octet-string. The value will pass through unmodified in an Odr_oct.
689 Added a bit of code to the demo client to decode & display
690 ASN.1-structured records represented in the octet-aligned branch of
691 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
693 Added z_ext_getentbyref() to the ASN module. Doc updated.
695 * Completed the SCAN definition in the ASN module. This may break SCAN
696 code based on older YAZ-versions at compile-time. The fix is easy -
699 * Added 'displayTerm' and OtherInformation to the TermInfo structure
700 under the SCAN definition. Remember to initialize this, server-people.
702 Comstack should now support the WAIS protocol in TCP/IP mode. Note
703 that this does not extend to ODR and ASN.
705 Comstack allows insertion of established socket (primarily for
706 inetd-operation of servers). Doc updated.
708 Front-end server can now start from the inetd in TCP mode. Doc
715 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
716 the rank and record number.
718 Adjustments to the frontend server.
720 Fixed diagnostic BER dumper. It ignored the file argument.
724 Various changes to retrieval module.
726 Changed the union discriminators of the protocol files from enums to
727 ints paired with #defines.
729 *Changed oident.class to oident.oclass to avoid a reserved word in C++
732 *Changed operator in the RPN structure to 'roperator', again to avoid a
735 Fixed problems in Explain decoders/encoders.
739 Memory bug in log module fixed.
743 Occasional malloc() of 0 bytes fixed in d1_espec.c.
745 Bug in Explain DatabaseInfo module fixed.
747 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
751 The shift to v1.0 signals that we now consider the *core* functionality
752 of YAZ reasonably stable (the core being more or less equivalent to
753 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
754 tested (Explain not at all - though that will happen soonish).
756 Minor changes to code to support Windows port.
758 Various minor changes after we're getting to use GRS-1 & co. more.
760 Added Espec-1 format.
762 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
763 of the protocol and it cannot be selected when encoding (maps into 'string'
764 when decoding). Needed to talk to some servers.
766 Demo client can request simple element set names.
768 Added Diagnostic Format encoders/decoders.
770 Added simple Close handling to frontend server (no hooks for resource
771 reporting yet), and demonstration client.
773 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
777 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
778 handled incorrectly when records were requested in the searchResponse. This
779 will only affect you if you use the frontend-server.
781 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
782 Test-client will ask for and print GRS1. Ztest will return dummy records
785 Added Explain encoders/decoders to the service-level API. Untested.
787 Added Extended Services: Item Order encoders and decoders to the Service-
788 level API. Untested. We could use a recent copy of the pertinent bits
789 of the ILL protocol to add those bits.
791 Added diagnostic format 1 encoders/decoders to the service-level API.
794 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
795 odr_cons.c, which causes a more correct output.
797 Fixed handling of searchRequest in frontend server. NextResultSetPosition
798 was always set to 0 when no records were requested in the searchRequest.
800 * Added better external-handling. This shouldn't harm old code that
801 *encodes* externals. It can break code that looks for a
802 'single-ASN1-type' representation, since those types that are known
803 are now decoded immediately. Look at the SUTRS sample code in
804 seshigh.c and client.c. Documentation updated.
806 Handling of structured records in bend_fetchresponse. Length -1 marks
807 structured record, type is deduced from format field.
810 Fairly quick maintenance release to add SUTRS support.
812 Fixed handling of SUTRS records in the demonstration client.
814 * Added format field to the bend_fetchrequest and bend_fetchresponce
815 structures of the backend API (frontend server). When the record is
816 returned, the value of the format field is mapped to an OID. The
817 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
818 of the record. The special value VAL_NONE in the bend_request means
819 that no specific format was requested by the client. Documentation
820 updated accordingly. Test server (ztest) will return a fixed dummy
821 SUTRS record if your client requests SUTRS.
823 Documentation updated accordingly.
825 You can now set external libraries and RANLIB support in the top-level
829 First public release.
