1 Possible compatibility problems with earlier versions marked with '*'.
3 PQF parser rejects bad queries - including those with extra
4 characters in them. PQF parser used to silently ignore that.
5 Cleaner API for PQF added, which allows you to get detailed
6 error information for bad queries (see yaz/pquery.h).
8 Implemented mini iconv library supporting conversions between
9 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
11 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
15 Fixed ZOOM C record cache so that preferredRecordSyntax and
16 elementSetName is used to check for already fetched records.
20 Added three members in bend_initrequest structure to facilitate
21 character set negotiation.
23 Fixed a bug in frontend server that could cause indefinite
24 loops under rare conditions.
26 Revised character set utilities (charneg.h) so that encoding
27 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
29 For PQF, directive @term <type> sets term type for Scan/Search.
30 Here <type> is general, string, numeric, null. The term type
31 is inherited - just like @attr.
33 New call odr_set_charset that sets character set conversion for
34 international-strings on a ODR stream. Prototype is:
35 int odr_set_charset(ODR o, const char *to, const char *from);
36 The InternationalString is still represented as C string in YAZ
37 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
38 won't). On the protocol level, you can use any encoding.
40 Support for UNIX sockets in ZOOM.
42 Solaris recv sometimes returns errno == ENOENT. It is treated as
43 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
45 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
46 both client and server. Code by Morten Bøgeskov.
50 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
51 that they can be used directly from Visual Basic. You must recompile
52 your windows APP if you're using ZOOM.
54 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
55 Commands "lang" and "charset" sets language and character set respectively.
56 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
57 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
59 Attributes from multiple CCL fields may be OR'ed rather than merged
60 using directive "@field or". Fields are still merged by default -
61 equivalent to "@field merge".
63 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
66 Fixed bug in zget for parameter ExtendedServicesResponse.
72 Added PQF feature: '@attr type=value' may be written as '@type=value'.
74 Client displays USR.1:SearchResult-1 (hits per term).
76 Additional Search Info for search in Generic Frontend Server.
78 Fixed CCL parsing of "field=s".
80 WIN32 installer - using the excellent NSIS software from nullsoft.
82 Fixed CCL parsing of "field = - <number>".
84 Added function yaz_marc_decode that decodes MARC for line mode
85 display or XML (similar to that used by JZKit).
87 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
88 Z39.50. But ISO/ILL was, however.
90 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
91 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

94 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
98 New YAZ client features: Command completion and new commands:
99 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
100 Code provided by Jacob Poulsen.
102 New call oid_trav, that visits all registered OIDs via callback.
104 Function ZOOM_record_get now returns const char pointer rather than
105 void pointer. It saves a lot of type casts.
107 For YAZ client, command "auth" now allows you to set authentication
108 in IdPass style. It is enabled when three tokens are given - order
109 is user, group and password.
111 Fix memory leaks in MARC record handling for ZOOM.
113 New option for YAZ client, -k <kilobytes> that sets
114 maximum record size. Similar to -k option for generic frontend
115 server and yaz-ztest.
117 More fixes for scan. Non-zero stepSize handled. OID's fixes.
119 Prefix query parser reports "fail" when bad attribute set is given.
121 Fix in MARC decoder. Proximity logging. Fix for attribute set
122 in scan handler for server. Patches by Shigeru Ishida.
124 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
127 Configure option --with-openssl=<dir> now works when a directory is
128 specified. Patch provided by Morten Bøgeskov.
130 New option for YAZ client, -u <auth>, that sets authentication.
132 ZOOM fix: error information was sometimes "missing", since error
133 was cleared/reset too when it shouldn't.
135 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
139 Scan for ZOOM API. New object ZOOM_scanset. New functions
140 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
141 ZOOM_scanset_destroy.
143 New ZOOM function, ZOOM_connection_last_event, that returns type
144 of last event (such as "receive data", "send data", "apdu received",
147 New ZOOM option, schema, that specifies shema OID for retrieval.
149 New CCL feature. Qualifiers can be aliases for one or more
150 other qualifiers (if more than one is given, OR is used).
152 ZOOM uses named result sets if target supports it.
154 Two new YAZ client commands: . (dot, which sources a script of YAZ
155 client commands), and ! (to execute shell command.). Implemented
158 Working on Debian packages.
162 YAZ client enables named result sets only if target supports it.
164 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
166 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
167 with key="host" to get same result.
169 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
170 Function Z3950_resultset_record(s) returns references to records
171 "owned" by resultset. To become owner use Z3950_record_clone.
173 Function z_ext_record handles Extended Services. Thanks to
178 CCL Parser fix: ignore token comma when dealing with and-lists.
180 Documentation updates for COMSTACK.
182 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
183 Changed prototype Z3950_records. For some functions, int parameters
184 were changed to size_t.
186 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
189 New MARC decode/display function, marc_display_exl, which properly rejects
190 non-ISO2709 records. YAZ client uses it.
194 Fix bug: local attribute set wasn't set correctly in PQF strings.
198 * Old Z39.50 codecs no longer supported.
200 Added ZOOM C binding. See http://zoom.z3950.org/
202 Renamed states for COMSTACKs to avoid confusion with events.
204 Implemented cs_look and proper cs_rcvconnect.
206 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
208 Configure detects POSIX threads on OpenBSD.
210 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
211 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
213 When error is returned from present handler, non-surrogate diagnostic
214 is returned in present response (and fetch handler is no longer called).
216 * Minor adjustments to pquery parser (PQF). Token characters may be
217 escaped by using backslash (C-style).
219 PQF parser allows string attribute values to be specified. For @attr,
220 non-numeric characters after the equal-sign are treated as strings
221 (e.g. @attr 9=title).
223 CCL trunction character may be defined (@truncation in file)
225 * function zget_ExtendedServicesRequest sets waitAction to
226 waitIfPossible (was wait).
228 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
231 CCL operator names may be set in field definition files (CCL_bibset).
232 See ccl/bib1 for an example.
234 Fixes in ASN.1 compiler for C++ compatibility.
236 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
237 and "op_or" to avoid conflict with C++.
239 Fixed problem with GNU readline detection on Redhat 7.0.
241 Added step-size for Scan backend handler.
243 Fixed bug that made the frontend server crash when no attribute
244 set was specified for scan.
246 Front-end server automatically switches to original working directory
247 when installed as an NT service. Previously -w had to be specified to
250 Added extended attributes for retrieval module (data1), so that data1
251 records carry d1_readXML/SGML attributes. d1_read also supports
252 null-data rules ( <tag/>)
254 On UNIX when POSIX threads are available, a separate library libyazthread
255 is created. Programmers should link with that library and the yaz library
256 when using threads. The reason for the split was that some applications
257 on Linux, such as Apache, doesn't work well when using shared objects that
260 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
261 (or any frontend server) in SSL mode by specifying ssl: followed by
262 address. Only tested on UNIX.
264 Added feature for CCL module. Virtual structure s=al or s=ol generates
265 and-list and or-list respectively instead of phrase search.
269 * Added prefix "yaz_" for the functions log_init.., log_file.. and
270 log_mask_str. This was done to avoid name conflicts with other libraries
271 (such as other PHP extensions).
273 Added raw OID member for preferred record syntax (request_format_raw)
274 and returned record syntax (output_format_raw) for backend fetch method.
276 Config file yaz-config now accepts options so that it returns specific
277 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
279 Shared library support for UNIX using GNU libtool.
281 * Modified backend interface. Request/Response struct's replaced by
282 one read/write C struct. For example bend_fetchrequest and
283 bend_fetchresult have been replaced by single bend_fetch_rr struct.
284 Every handler - even search has to be registered in bend_init
285 handler. This means that the YAZ library no longer refers to
286 external functions and it makes it possible to make the whole
287 thing a single DLL/SO.
289 Added Segment handler for backend server.
291 Added Zmbol/Zebra administrative functions to YAZ client.
293 Threaded frontend server on UNIX (when POSIX Threads are available).
294 Starting the server with option -T enables multi-threading.
298 Added configure option --enable-comp/disable-comp to control use
299 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
300 located in sub directory asn.
302 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
303 in ${exec_prefix}/bin along with the other programs yaz-client and
306 GNU automake used to maintain makefiles.
310 Changed retrieval module so that we can load records with no abstract
311 syntax defined. Tagpaths in these records are fully composed of string
314 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
318 On UNIX, the generated makefile now supports a proper 'make install'.
319 The prefix can be set via GNU configure to set the install location
320 (default is /usr/local).
322 * YAZ programs client and ztest were renamed to yaz-client and
323 yaz-ztest to avoid conflicts when users install YAZ in "standard"
324 locations, such as /usr/bin,/usr/local/bin,etc.
326 * YAZ Header files were moved from include to include/yaz. YAZ Header
327 files are referred to as include <yaz/log.h> rather than <log.h>.
328 The YAZ include path (-I ..) is therefore the same as before. Programmers
329 should update their #include statements or use -Ipath/include/yaz
330 instead. The main motivation for doing this change is that YAZ header files
331 can be installed in "standard" locations /usr/include,/usr/local/include
332 without introducing conflicts, since ALL YAZ header files are stored
333 in subdirectory yaz (under /usr/include for example).
335 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
336 rather than project/workspace files. We switched because project files
337 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
340 Changed name of logging function, logf, to yaz_log, to prevent name
341 clash with some math-log functions. The YAZ header log.h defines logf
342 to yaz_log (#define) so there should be no incompatibilities by this
345 Added bend_start/bend_stop handlers for server. These handler are
346 called on start/stop of server. For windows they are called whenever
347 a service is started/stopped.
349 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
350 a fairly small ASN.1 compiler written in Tcl. The compiler is located
351 in util/yc.tcl. The auto-generated C code structures are, in a few
352 cases, incompatible with the old decoders. There are differences in the
353 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
354 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
355 The preprocessor variable ASN_COMPILED is defined when the compiled
356 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
357 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
358 wish to use the old encoders/decoders you can specify --disable-yc
361 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
362 version so that it supports both new - and old version of DB Update
364 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
365 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
366 change. The name parameter can be set to 0 in which no name is specified
367 for the construction. The macros odr_implicit and odr_explicit sets name
368 parameter to zero for the construction involved. New macros
369 odr_implicit_tag and odr_explicit_tag are similar to the others,
370 except that a name parameter is added. For programmers' that don't use
371 ODR they probably only need to change the call to z_APDU and z_External.
373 Added access control facility by interfacing the TCP wrapper library.
374 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
375 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
376 name of the daemon and enables the access control as specified in
377 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
379 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
380 den Dool <H.M.vdnDool@kub.nl>.
382 Added reference ID parameter to most functions in server API - refer
383 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
385 Changed name of ccl library to libccl.a (was ccl.a).
387 Fixed bug in decoder for Explain (Category TargetInfo).
389 Added support for GNU readline in client. Thanks to Jacob Poulsen
390 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
392 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
393 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
394 IMPLEMENTATION! This change was made to the development version before
395 the ZIG decided to retract the amendment. If any users MUST be
396 compatible with the original Update definition, PLEASE CONTACT US, and
397 we will include a separate definition corresponding to the old Update
398 ES. Note that because of the change to the ASN.1 of the
399 TaskPackageRecordStructure we cannot define a single structure that
400 will support both versions.
402 * Added const modifier to buffer parameter for some ODR/BER encoding
403 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
404 completeWAIS, odr_dumpBER.
406 Fixed bug in client.c which caused a crash when a scanResponse didn't
407 contain positionOfTerm.
409 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
410 * will cause an error in a client if a non-YAZ target sends both a
411 * list of Scan entries and non-surrogate diagnostics.
413 Retrieval module enhancements. Tag sets may be typed in the reference
414 to it. From the .abs-file the "tagset" directive takes a third optional
415 integer type for the tag set referenced. From a .tag-file the "include"
416 directive takes a third optional type as well. The old "type" directive
417 in the tag set itself is still recognized but acts as the default type
420 Backend interface change. Individual Scan terms returned from bend_scan
421 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
422 in include/backend.h.
424 Retrieval module enhancements. Multiple tag sets and attribute sets may
425 be specified in abstract syntax specs. Revised the error/warning for
426 logging messages reported by the retrieval module when reading the
429 Object Identifier system (oid_..) changed. The API is backwards
430 compatible but the oid-routines now allocates new OID's when needed.
431 Raw OID's may be specified in oid_getvalbyname.
433 YAZ now uses GNU configure to generate Makefile(s).
435 * Minor changes in some of the member names of DeleteResultSetRequest and
436 DeleteResultSetResponse. See include/proto.h.
438 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
439 and added member 'languages' in TargetInfo (which was missing).
441 Changed the way attribute sets are handled in the retrieval
442 module. These are now cached, just like the abstract syntaxes
445 Changed YAZ so that it links with compiled ASN.1.
447 Added Explain-schema definitions and mapping routines. The following
448 Explain categories have been implemented: AttributeDetails,
449 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
451 Fixed minor bug in Windows version of Server Library.
453 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
455 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
457 Added EXTERNAL: UNIverse Resource Report (non-standard).
459 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
460 ENUMERATED and SET OF.
462 * Added 'const' to some of the char pointer arguments for the
463 functions, data1_read_node, data1_getelementbytagname,
464 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
467 Fixed bug in data1_insert_taggeddata - the last_child member of
468 parent wasn't initialised.
470 * Changed data1_read_record and data1_read_node so that the supplied
471 "SGML"-buffer is read-only. In particular the resulting data1 - tree
472 doesn't refer to any parts of the "SGML"-buffer.
474 Fixed bug in server library (Windows version of statserv_remove).
476 * Changed code so that it compiles as C++. The type definition
477 of Odr_fun which is a member of Odr_arm was changed. The result is,
478 that an explicit typecast is needed for the fun pointer when
479 using Odr_arm - as in:
480 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
482 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
484 Implemented the new structured date and time definition as approved
485 by the ZIG. Added schemaId element to the specificTag in Espec-1
486 (also approved at the last ZIG). Thanks to RVDM.
488 Added some Object identifiers (RVDM).
490 Changed the Update Extended Service (RVDM).
492 Added command "refid" to client which specifies referenceId for
493 the following requests.
495 Implemented extended service handling for server. See ztest.c
496 for an example as well as backend.h. New handlers are registerd
499 * Changed interface for sort in server.
501 Added new members to statserv_options_block. It allows a server
502 to read options from another source than just the command line. Thanks
503 to Charles Woodfield.
505 * Changed definition of Z_Triple in file prt-grs.h - member boolean
506 renamed to zboolean. Some C++ compilers complained about the name.
508 Minor changes to gils.abs. Added index 's' (sort) on title
509 and date/time-last-modified.
513 Fixed bug in server library regarding inetd mode (-i). This bug
514 was introduced by release 1.4.
518 Added sort facility in client and backend server interface.
520 Fixed problem with dependencies in Makefile(s).
522 Fixed bugs for encoders/decoders of extended services and
525 Implemented sub-tree feature for schemas. Sub-trees are
526 referenced in *.abs-files. See explain.abs for an example
527 of the use of this feature.
529 Modified bib1.att; local attributes for ANY didn't include
530 ANY itself (only affects use of the retrieval module).
532 Fixed bug in plain SGML reader in function data1_read_node:
533 tags with prefix "var" was incorrectly interpreted as variants.
535 Added feature "sub-schemas" to enable references to - and definitions
536 of - group of elements.
538 * Removed member parent from type data1_element (in data1.h).
540 Implemented function odr_nullval() that returns the value of
543 * Removed member num_children from data1_node (in data1.h).
545 Made NT service interface part of the server library. The
546 function statserv_main uses the NT service when required and
547 calls the statserv_start / statserv_close routines.
549 Routine zget_SearchRequest and zget_PresentRequest fills
550 resultSetName/Id member with "default" instead of "Default".
552 Fixed memory leak in server. Request queue member wasn't freed.
554 Fixed nmem_exit so that memory is freed.
558 Revised the CCL parser utility to be thread safe.
560 Added function, oid_ent_to_oid, to replace the function
561 oid_getoidbyent, which is not thread safe.
563 * Added nmem_init and nmem_exit to initialize and release
564 NMEM resources. Function nmem_init should be called once in the
565 initial thread before NMEM/ODR is used. statserv.c and client.c
566 have been changed accordingly. The change was necessary to make
567 NMEM thread safe. The NMEM memory pool is shared amongst threads
568 in a process. Unix-based applications will still work fine without
571 Added NT Services interface for the the Z39.50 (statserv) Server.
572 Refer to the ztest.c source on the usage.
574 Windows 95/NT port using MSVC5.0. Project files are included in the
577 * Defined new 'global' handle for the retrieval (data1) system. The
578 new handled, data1_handle, describes the state of the data1 system.
579 This handle is passed as first argument to virtually all
580 data1 related routines. The functions data1_create and data1_destroy
581 creates and destroys a data1 handle respectively.
583 Added ODR encode stream member to all backend request structures
584 init, search, scan etc. This stream should be used to allocate all
585 memory used for the response when thread safe operation is needed.
587 Changed the comstack utility, cs_addstr, to be thread safe. The
588 returned hostname string returned by the function is now part the
591 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
592 function. The cs_straddr takes a COMSTACK handle as argument, so this
593 function must be used after cs_create and before bind/connect.
594 This function is thread safe.
596 Moved test server to 'ztest' directory - generic server code still
597 in 'server' directory.
599 Made prefix query (pquery.c) utility thread safe.
601 Added new function modifier YAZ_EXPORT to 'export' public DLL
602 functions when using windows (see include/yconfig.h).
604 Added definitions to the OID database (util/oid.c) (RVDM).
606 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
608 Added call to ccl_rpn_delete in client program.
610 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
611 release of RPN structure.
613 Added support for C++, headers uses extern "C" for public definitions.
614 With input from RVDM.
616 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
617 Thanks to Ronald van der Meer (RVDM).
619 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
621 Added support for private extensions to the OID database
622 (oid_setprivateoids()). Thanks to RVDM.
624 Added optional, physical ANY (key replication)
626 Fixed null-reference problem in GRS-1 output filter.
628 Proximity operator added to Prefix Query Format (PQF).
630 In test client command "base" accepts multiple databases.
632 Fixed bug in cs_close stack that caused trouble with WINSOCK.
636 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
638 Smallish bug-fixes in the new encoders/decoders (explain).
640 Bug fixed in DeleteRequest.
642 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
644 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
646 Added SOIF syntax (using private OID for now) to retrieval module and client.
648 Added Update extended service.
650 Added SearchResult-1 additional info structure.
652 Added optional CCL (ISO8777) interpreter as separate module. Available
655 --- 1.2 1996/6/10 (1st anniversary release)
657 Added Summary record syntax. Lightly tested.
659 Added OPAC record syntax. Untested.
661 Added ResourceReport service encoders/decoders. Untested.
663 Fixed bug in z_Unit - wrong tagging on unitSystem.
665 Fixed bug in the DiagRecs decoder.
667 Added options for max PDU size and session timeout to frontend-server.
669 Added documentation of query-language parsers and other supporting utilities.
671 [frontend-server] Added Attribute set to the bend_scanrequest API.
673 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
674 surrogate diagnostics were generated.
676 [retrieval] Allow multiple local values for attribute.
678 [retrieval] Allow multiple attributes per element in .abs files. index type.
680 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
684 Minor changes, mostly specific to Zebra's requirements (retrieval)
688 Repaired bug in frontend server when running multiple listening
689 endpoints in dynamic mode.
691 z_External() now won't break if a known, ASN.1 value comes encapsulated
692 in an octet-string. The value will pass through unmodified in an Odr_oct.
694 Added a bit of code to the demo client to decode & display
695 ASN.1-structured records represented in the octet-aligned branch of
696 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
698 Added z_ext_getentbyref() to the ASN module. Doc updated.
700 * Completed the SCAN definition in the ASN module. This may break SCAN
701 code based on older YAZ-versions at compile-time. The fix is easy -
704 * Added 'displayTerm' and OtherInformation to the TermInfo structure
705 under the SCAN definition. Remember to initialize this, server-people.
707 Comstack should now support the WAIS protocol in TCP/IP mode. Note
708 that this does not extend to ODR and ASN.
710 Comstack allows insertion of established socket (primarily for
711 inetd-operation of servers). Doc updated.
713 Front-end server can now start from the inetd in TCP mode. Doc
720 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
721 the rank and record number.
723 Adjustments to the frontend server.
725 Fixed diagnostic BER dumper. It ignored the file argument.
729 Various changes to retrieval module.
731 Changed the union discriminators of the protocol files from enums to
732 ints paired with #defines.
734 *Changed oident.class to oident.oclass to avoid a reserved word in C++
737 *Changed operator in the RPN structure to 'roperator', again to avoid a
740 Fixed problems in Explain decoders/encoders.
744 Memory bug in log module fixed.
748 Occasional malloc() of 0 bytes fixed in d1_espec.c.
750 Bug in Explain DatabaseInfo module fixed.
752 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
756 The shift to v1.0 signals that we now consider the *core* functionality
757 of YAZ reasonably stable (the core being more or less equivalent to
758 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
759 tested (Explain not at all - though that will happen soonish).
761 Minor changes to code to support Windows port.
763 Various minor changes after we're getting to use GRS-1 & co. more.
765 Added Espec-1 format.
767 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
768 of the protocol and it cannot be selected when encoding (maps into 'string'
769 when decoding). Needed to talk to some servers.
771 Demo client can request simple element set names.
773 Added Diagnostic Format encoders/decoders.
775 Added simple Close handling to frontend server (no hooks for resource
776 reporting yet), and demonstration client.
778 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
782 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
783 handled incorrectly when records were requested in the searchResponse. This
784 will only affect you if you use the frontend-server.
786 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
787 Test-client will ask for and print GRS1. Ztest will return dummy records
790 Added Explain encoders/decoders to the service-level API. Untested.
792 Added Extended Services: Item Order encoders and decoders to the Service-
793 level API. Untested. We could use a recent copy of the pertinent bits
794 of the ILL protocol to add those bits.
796 Added diagnostic format 1 encoders/decoders to the service-level API.
799 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
800 odr_cons.c, which causes a more correct output.
802 Fixed handling of searchRequest in frontend server. NextResultSetPosition
803 was always set to 0 when no records were requested in the searchRequest.
805 * Added better external-handling. This shouldn't harm old code that
806 *encodes* externals. It can break code that looks for a
807 'single-ASN1-type' representation, since those types that are known
808 are now decoded immediately. Look at the SUTRS sample code in
809 seshigh.c and client.c. Documentation updated.
811 Handling of structured records in bend_fetchresponse. Length -1 marks
812 structured record, type is deduced from format field.
815 Fairly quick maintenance release to add SUTRS support.
817 Fixed handling of SUTRS records in the demonstration client.
819 * Added format field to the bend_fetchrequest and bend_fetchresponce
820 structures of the backend API (frontend server). When the record is
821 returned, the value of the format field is mapped to an OID. The
822 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
823 of the record. The special value VAL_NONE in the bend_request means
824 that no specific format was requested by the client. Documentation
825 updated accordingly. Test server (ztest) will return a fixed dummy
826 SUTRS record if your client requests SUTRS.
828 Documentation updated accordingly.
830 You can now set external libraries and RANLIB support in the top-level
834 First public release.
