1 Possible compatibility problems with earlier versions marked with '*'.
5 Added PQF feature: '@attr type=value' may be written as '@type=value'.
7 Client displays USR.1:SearchResult-1 (hits per term).
9 Additional Search Info for search in Generic Frontend Server.
11 Fixed CCL parsing of "field=s".
13 WIN32 installer - using the excellent NSIS software from nullsoft.
15 Fixed CCL parsing of "field = - <number>".
17 Added function yaz_marc_decode that decodes MARC for line mode
18 display or XML (similar to that used by JZKit).
20 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
21 Z39.50. But ISO/ILL was, however.
23 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
24 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

31 New YAZ client features: Command completion and new commands:
32 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
33 Code provided by Jacob Poulsen.
35 New call oid_trav, that visits all registered OIDs via callback.
37 Function ZOOM_record_get now returns const char pointer rather than
38 void pointer. It saves a lot of type casts.
40 For YAZ client, command "auth" now allows you to set authentication
41 in IdPass style. It is enabled when three tokens are given - order
42 is user, group and password.
44 Fix memory leaks in MARC record handling for ZOOM.
46 New option for YAZ client, -k <kilobytes> that sets
47 maximum record size. Similar to -k option for generic frontend
50 More fixes for scan. Non-zero stepSize handled. OID's fixes.
52 Prefix query parser reports "fail" when bad attribute set is given.
54 Fix in MARC decoder. Proximity logging. Fix for attribute set
55 in scan handler for server. Patches by Shigeru Ishida.
57 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
60 Configure option --with-openssl=<dir> now works when a directory is
61 specified. Patch provided by Morten Bøgeskov.
63 New option for YAZ client, -u <auth>, that sets authentication.
65 ZOOM fix: error information was sometimes "missing", since error
66 was cleared/reset too when it shouldn't.
68 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
72 Scan for ZOOM API. New object ZOOM_scanset. New functions
73 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
76 New ZOOM function, ZOOM_connection_last_event, that returns type
77 of last event (such as "receive data", "send data", "apdu received",
80 New ZOOM option, schema, that specifies shema OID for retrieval.
82 New CCL feature. Qualifiers can be aliases for one or more
83 other qualifiers (if more than one is given, OR is used).
85 ZOOM uses named result sets if target supports it.
87 Two new YAZ client commands: . (dot, which sources a script of YAZ
88 client commands), and ! (to execute shell command.). Implemented
91 Working on Debian packages.
95 YAZ client enables named result sets only if target supports it.
97 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
99 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
100 with key="host" to get same result.
102 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
103 Function Z3950_resultset_record(s) returns references to records
104 "owned" by resultset. To become owner use Z3950_record_clone.
106 Function z_ext_record handles Extended Services. Thanks to
111 CCL Parser fix: ignore token comma when dealing with and-lists.
113 Documentation updates for COMSTACK.
115 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
116 Changed prototype Z3950_records. For some functions, int parameters
117 were changed to size_t.
119 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
122 New MARC decode/display function, marc_display_exl, which properly rejects
123 non-ISO2709 records. YAZ client uses it.
127 Fix bug: local attribute set wasn't set correctly in PQF strings.
131 * Old Z39.50 codecs no longer supported.
133 Added ZOOM C binding. See http://zoom.z3950.org/
135 Renamed states for COMSTACKs to avoid confusion with events.
137 Implemented cs_look and proper cs_rcvconnect.
139 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
141 Configure detects POSIX threads on OpenBSD.
143 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
144 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
146 When error is returned from present handler, non-surrogate diagnostic
147 is returned in present response (and fetch handler is no longer called).
149 * Minor adjustments to pquery parser (PQF). Token characters may be
150 escaped by using backslash (C-style).
152 PQF parser allows string attribute values to be specified. For @attr,
153 non-numeric characters after the equal-sign are treated as strings
154 (e.g. @attr 9=title).
156 CCL trunction character may be defined (@truncation in file)
158 * function zget_ExtendedServicesRequest sets waitAction to
159 waitIfPossible (was wait).
161 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
164 CCL operator names may be set in field definition files (CCL_bibset).
165 See ccl/bib1 for an example.
167 Fixes in ASN.1 compiler for C++ compatibility.
169 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
170 and "op_or" to avoid conflict with C++.
172 Fixed problem with GNU readline detection on Redhat 7.0.
174 Added step-size for Scan backend handler.
176 Fixed bug that made the frontend server crash when no attribute
177 set was specified for scan.
179 Front-end server automatically switches to original working directory
180 when installed as an NT service. Previously -w had to be specified to
183 Added extended attributes for retrieval module (data1), so that data1
184 records carry d1_readXML/SGML attributes. d1_read also supports
185 null-data rules ( <tag/>)
187 On UNIX when POSIX threads are available, a separate library libyazthread
188 is created. Programmers should link with that library and the yaz library
189 when using threads. The reason for the split was that some applications
190 on Linux, such as Apache, doesn't work well when using shared objects that
193 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
194 (or any frontend server) in SSL mode by specifying ssl: followed by
195 address. Only tested on UNIX.
197 Added feature for CCL module. Virtual structure s=al or s=ol generates
198 and-list and or-list respectively instead of phrase search.
202 * Added prefix "yaz_" for the functions log_init.., log_file.. and
203 log_mask_str. This was done to avoid name conflicts with other libraries
204 (such as other PHP extensions).
206 Added raw OID member for preferred record syntax (request_format_raw)
207 and returned record syntax (output_format_raw) for backend fetch method.
209 Config file yaz-config now accepts options so that it returns specific
210 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
212 Shared library support for UNIX using GNU libtool.
214 * Modified backend interface. Request/Response struct's replaced by
215 one read/write C struct. For example bend_fetchrequest and
216 bend_fetchresult have been replaced by single bend_fetch_rr struct.
217 Every handler - even search has to be registered in bend_init
218 handler. This means that the YAZ library no longer refers to
219 external functions and it makes it possible to make the whole
220 thing a single DLL/SO.
222 Added Segment handler for backend server.
224 Added Zmbol/Zebra administrative functions to YAZ client.
226 Threaded frontend server on UNIX (when POSIX Threads are available).
227 Starting the server with option -T enables multi-threading.
231 Added configure option --enable-comp/disable-comp to control use
232 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
233 located in sub directory asn.
235 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
236 in ${exec_prefix}/bin along with the other programs yaz-client and
239 GNU automake used to maintain makefiles.
243 Changed retrieval module so that we can load records with no abstract
244 syntax defined. Tagpaths in these records are fully composed of string
247 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
251 On UNIX, the generated makefile now supports a proper 'make install'.
252 The prefix can be set via GNU configure to set the install location
253 (default is /usr/local).
255 * YAZ programs client and ztest were renamed to yaz-client and
256 yaz-ztest to avoid conflicts when users install YAZ in "standard"
257 locations, such as /usr/bin,/usr/local/bin,etc.
259 * YAZ Header files were moved from include to include/yaz. YAZ Header
260 files are referred to as include <yaz/log.h> rather than <log.h>.
261 The YAZ include path (-I ..) is therefore the same as before. Programmers
262 should update their #include statements or use -Ipath/include/yaz
263 instead. The main motivation for doing this change is that YAZ header files
264 can be installed in "standard" locations /usr/include,/usr/local/include
265 without introducing conflicts, since ALL YAZ header files are stored
266 in subdirectory yaz (under /usr/include for example).
268 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
269 rather than project/workspace files. We switched because project files
270 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
273 Changed name of logging function, logf, to yaz_log, to prevent name
274 clash with some math-log functions. The YAZ header log.h defines logf
275 to yaz_log (#define) so there should be no incompatibilities by this
278 Added bend_start/bend_stop handlers for server. These handler are
279 called on start/stop of server. For windows they are called whenever
280 a service is started/stopped.
282 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
283 a fairly small ASN.1 compiler written in Tcl. The compiler is located
284 in util/yc.tcl. The auto-generated C code structures are, in a few
285 cases, incompatible with the old decoders. There are differences in the
286 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
287 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
288 The preprocessor variable ASN_COMPILED is defined when the compiled
289 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
290 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
291 wish to use the old encoders/decoders you can specify --disable-yc
294 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
295 version so that it supports both new - and old version of DB Update
297 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
298 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
299 change. The name parameter can be set to 0 in which no name is specified
300 for the construction. The macros odr_implicit and odr_explicit sets name
301 parameter to zero for the construction involved. New macros
302 odr_implicit_tag and odr_explicit_tag are similar to the others,
303 except that a name parameter is added. For programmers' that don't use
304 ODR they probably only need to change the call to z_APDU and z_External.
306 Added access control facility by interfacing the TCP wrapper library.
307 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
308 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
309 name of the daemon and enables the access control as specified in
310 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
312 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
313 den Dool <H.M.vdnDool@kub.nl>.
315 Added reference ID parameter to most functions in server API - refer
316 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
318 Changed name of ccl library to libccl.a (was ccl.a).
320 Fixed bug in decoder for Explain (Category TargetInfo).
322 Added support for GNU readline in client. Thanks to Jacob Poulsen
323 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
325 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
326 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
327 IMPLEMENTATION! This change was made to the development version before
328 the ZIG decided to retract the amendment. If any users MUST be
329 compatible with the original Update definition, PLEASE CONTACT US, and
330 we will include a separate definition corresponding to the old Update
331 ES. Note that because of the change to the ASN.1 of the
332 TaskPackageRecordStructure we cannot define a single structure that
333 will support both versions.
335 * Added const modifier to buffer parameter for some ODR/BER encoding
336 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
337 completeWAIS, odr_dumpBER.
339 Fixed bug in client.c which caused a crash when a scanResponse didn't
340 contain positionOfTerm.
342 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
343 * will cause an error in a client if a non-YAZ target sends both a
344 * list of Scan entries and non-surrogate diagnostics.
346 Retrieval module enhancements. Tag sets may be typed in the reference
347 to it. From the .abs-file the "tagset" directive takes a third optional
348 integer type for the tag set referenced. From a .tag-file the "include"
349 directive takes a third optional type as well. The old "type" directive
350 in the tag set itself is still recognized but acts as the default type
353 Backend interface change. Individual Scan terms returned from bend_scan
354 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
355 in include/backend.h.
357 Retrieval module enhancements. Multiple tag sets and attribute sets may
358 be specified in abstract syntax specs. Revised the error/warning for
359 logging messages reported by the retrieval module when reading the
362 Object Identifier system (oid_..) changed. The API is backwards
363 compatible but the oid-routines now allocates new OID's when needed.
364 Raw OID's may be specified in oid_getvalbyname.
366 YAZ now uses GNU configure to generate Makefile(s).
368 * Minor changes in some of the member names of DeleteResultSetRequest and
369 DeleteResultSetResponse. See include/proto.h.
371 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
372 and added member 'languages' in TargetInfo (which was missing).
374 Changed the way attribute sets are handled in the retrieval
375 module. These are now cached, just like the abstract syntaxes
378 Changed YAZ so that it links with compiled ASN.1.
380 Added Explain-schema definitions and mapping routines. The following
381 Explain categories have been implemented: AttributeDetails,
382 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
384 Fixed minor bug in Windows version of Server Library.
386 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
388 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
390 Added EXTERNAL: UNIverse Resource Report (non-standard).
392 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
393 ENUMERATED and SET OF.
395 * Added 'const' to some of the char pointer arguments for the
396 functions, data1_read_node, data1_getelementbytagname,
397 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
400 Fixed bug in data1_insert_taggeddata - the last_child member of
401 parent wasn't initialised.
403 * Changed data1_read_record and data1_read_node so that the supplied
404 "SGML"-buffer is read-only. In particular the resulting data1 - tree
405 doesn't refer to any parts of the "SGML"-buffer.
407 Fixed bug in server library (Windows version of statserv_remove).
409 * Changed code so that it compiles as C++. The type definition
410 of Odr_fun which is a member of Odr_arm was changed. The result is,
411 that an explicit typecast is needed for the fun pointer when
412 using Odr_arm - as in:
413 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
415 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
417 Implemented the new structured date and time definition as approved
418 by the ZIG. Added schemaId element to the specificTag in Espec-1
419 (also approved at the last ZIG). Thanks to RVDM.
421 Added some Object identifiers (RVDM).
423 Changed the Update Extended Service (RVDM).
425 Added command "refid" to client which specifies referenceId for
426 the following requests.
428 Implemented extended service handling for server. See ztest.c
429 for an example as well as backend.h. New handlers are registerd
432 * Changed interface for sort in server.
434 Added new members to statserv_options_block. It allows a server
435 to read options from another source than just the command line. Thanks
436 to Charles Woodfield.
438 * Changed definition of Z_Triple in file prt-grs.h - member boolean
439 renamed to zboolean. Some C++ compilers complained about the name.
441 Minor changes to gils.abs. Added index 's' (sort) on title
442 and date/time-last-modified.
446 Fixed bug in server library regarding inetd mode (-i). This bug
447 was introduced by release 1.4.
451 Added sort facility in client and backend server interface.
453 Fixed problem with dependencies in Makefile(s).
455 Fixed bugs for encoders/decoders of extended services and
458 Implemented sub-tree feature for schemas. Sub-trees are
459 referenced in *.abs-files. See explain.abs for an example
460 of the use of this feature.
462 Modified bib1.att; local attributes for ANY didn't include
463 ANY itself (only affects use of the retrieval module).
465 Fixed bug in plain SGML reader in function data1_read_node:
466 tags with prefix "var" was incorrectly interpreted as variants.
468 Added feature "sub-schemas" to enable references to - and definitions
469 of - group of elements.
471 * Removed member parent from type data1_element (in data1.h).
473 Implemented function odr_nullval() that returns the value of
476 * Removed member num_children from data1_node (in data1.h).
478 Made NT service interface part of the server library. The
479 function statserv_main uses the NT service when required and
480 calls the statserv_start / statserv_close routines.
482 Routine zget_SearchRequest and zget_PresentRequest fills
483 resultSetName/Id member with "default" instead of "Default".
485 Fixed memory leak in server. Request queue member wasn't freed.
487 Fixed nmem_exit so that memory is freed.
491 Revised the CCL parser utility to be thread safe.
493 Added function, oid_ent_to_oid, to replace the function
494 oid_getoidbyent, which is not thread safe.
496 * Added nmem_init and nmem_exit to initialize and release
497 NMEM resources. Function nmem_init should be called once in the
498 initial thread before NMEM/ODR is used. statserv.c and client.c
499 have been changed accordingly. The change was necessary to make
500 NMEM thread safe. The NMEM memory pool is shared amongst threads
501 in a process. Unix-based applications will still work fine without
504 Added NT Services interface for the the Z39.50 (statserv) Server.
505 Refer to the ztest.c source on the usage.
507 Windows 95/NT port using MSVC5.0. Project files are included in the
510 * Defined new 'global' handle for the retrieval (data1) system. The
511 new handled, data1_handle, describes the state of the data1 system.
512 This handle is passed as first argument to virtually all
513 data1 related routines. The functions data1_create and data1_destroy
514 creates and destroys a data1 handle respectively.
516 Added ODR encode stream member to all backend request structures
517 init, search, scan etc. This stream should be used to allocate all
518 memory used for the response when thread safe operation is needed.
520 Changed the comstack utility, cs_addstr, to be thread safe. The
521 returned hostname string returned by the function is now part the
524 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
525 function. The cs_straddr takes a COMSTACK handle as argument, so this
526 function must be used after cs_create and before bind/connect.
527 This function is thread safe.
529 Moved test server to 'ztest' directory - generic server code still
530 in 'server' directory.
532 Made prefix query (pquery.c) utility thread safe.
534 Added new function modifier YAZ_EXPORT to 'export' public DLL
535 functions when using windows (see include/yconfig.h).
537 Added definitions to the OID database (util/oid.c) (RVDM).
539 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
541 Added call to ccl_rpn_delete in client program.
543 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
544 release of RPN structure.
546 Added support for C++, headers uses extern "C" for public definitions.
547 With input from RVDM.
549 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
550 Thanks to Ronald van der Meer (RVDM).
552 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
554 Added support for private extensions to the OID database
555 (oid_setprivateoids()). Thanks to RVDM.
557 Added optional, physical ANY (key replication)
559 Fixed null-reference problem in GRS-1 output filter.
561 Proximity operator added to Prefix Query Format (PQF).
563 In test client command "base" accepts multiple databases.
565 Fixed bug in cs_close stack that caused trouble with WINSOCK.
569 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
571 Smallish bug-fixes in the new encoders/decoders (explain).
573 Bug fixed in DeleteRequest.
575 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
577 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
579 Added SOIF syntax (using private OID for now) to retrieval module and client.
581 Added Update extended service.
583 Added SearchResult-1 additional info structure.
585 Added optional CCL (ISO8777) interpreter as separate module. Available
588 --- 1.2 1996/6/10 (1st anniversary release)
590 Added Summary record syntax. Lightly tested.
592 Added OPAC record syntax. Untested.
594 Added ResourceReport service encoders/decoders. Untested.
596 Fixed bug in z_Unit - wrong tagging on unitSystem.
598 Fixed bug in the DiagRecs decoder.
600 Added options for max PDU size and session timeout to frontend-server.
602 Added documentation of query-language parsers and other supporting utilities.
604 [frontend-server] Added Attribute set to the bend_scanrequest API.
606 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
607 surrogate diagnostics were generated.
609 [retrieval] Allow multiple local values for attribute.
611 [retrieval] Allow multiple attributes per element in .abs files. index type.
613 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
617 Minor changes, mostly specific to Zebra's requirements (retrieval)
621 Repaired bug in frontend server when running multiple listening
622 endpoints in dynamic mode.
624 z_External() now won't break if a known, ASN.1 value comes encapsulated
625 in an octet-string. The value will pass through unmodified in an Odr_oct.
627 Added a bit of code to the demo client to decode & display
628 ASN.1-structured records represented in the octet-aligned branch of
629 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
631 Added z_ext_getentbyref() to the ASN module. Doc updated.
633 * Completed the SCAN definition in the ASN module. This may break SCAN
634 code based on older YAZ-versions at compile-time. The fix is easy -
637 * Added 'displayTerm' and OtherInformation to the TermInfo structure
638 under the SCAN definition. Remember to initialize this, server-people.
640 Comstack should now support the WAIS protocol in TCP/IP mode. Note
641 that this does not extend to ODR and ASN.
643 Comstack allows insertion of established socket (primarily for
644 inetd-operation of servers). Doc updated.
646 Front-end server can now start from the inetd in TCP mode. Doc
653 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
654 the rank and record number.
656 Adjustments to the frontend server.
658 Fixed diagnostic BER dumper. It ignored the file argument.
662 Various changes to retrieval module.
664 Changed the union discriminators of the protocol files from enums to
665 ints paired with #defines.
667 *Changed oident.class to oident.oclass to avoid a reserved word in C++
670 *Changed operator in the RPN structure to 'roperator', again to avoid a
673 Fixed problems in Explain decoders/encoders.
677 Memory bug in log module fixed.
681 Occasional malloc() of 0 bytes fixed in d1_espec.c.
683 Bug in Explain DatabaseInfo module fixed.
685 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
689 The shift to v1.0 signals that we now consider the *core* functionality
690 of YAZ reasonably stable (the core being more or less equivalent to
691 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
692 tested (Explain not at all - though that will happen soonish).
694 Minor changes to code to support Windows port.
696 Various minor changes after we're getting to use GRS-1 & co. more.
698 Added Espec-1 format.
700 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
701 of the protocol and it cannot be selected when encoding (maps into 'string'
702 when decoding). Needed to talk to some servers.
704 Demo client can request simple element set names.
706 Added Diagnostic Format encoders/decoders.
708 Added simple Close handling to frontend server (no hooks for resource
709 reporting yet), and demonstration client.
711 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
715 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
716 handled incorrectly when records were requested in the searchResponse. This
717 will only affect you if you use the frontend-server.
719 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
720 Test-client will ask for and print GRS1. Ztest will return dummy records
723 Added Explain encoders/decoders to the service-level API. Untested.
725 Added Extended Services: Item Order encoders and decoders to the Service-
726 level API. Untested. We could use a recent copy of the pertinent bits
727 of the ILL protocol to add those bits.
729 Added diagnostic format 1 encoders/decoders to the service-level API.
732 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
733 odr_cons.c, which causes a more correct output.
735 Fixed handling of searchRequest in frontend server. NextResultSetPosition
736 was always set to 0 when no records were requested in the searchRequest.
738 * Added better external-handling. This shouldn't harm old code that
739 *encodes* externals. It can break code that looks for a
740 'single-ASN1-type' representation, since those types that are known
741 are now decoded immediately. Look at the SUTRS sample code in
742 seshigh.c and client.c. Documentation updated.
744 Handling of structured records in bend_fetchresponse. Length -1 marks
745 structured record, type is deduced from format field.
748 Fairly quick maintenance release to add SUTRS support.
750 Fixed handling of SUTRS records in the demonstration client.
752 * Added format field to the bend_fetchrequest and bend_fetchresponce
753 structures of the backend API (frontend server). When the record is
754 returned, the value of the format field is mapped to an OID. The
755 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
756 of the record. The special value VAL_NONE in the bend_request means
757 that no specific format was requested by the client. Documentation
758 updated accordingly. Test server (ztest) will return a fixed dummy
759 SUTRS record if your client requests SUTRS.
761 Documentation updated accordingly.
763 You can now set external libraries and RANLIB support in the top-level
767 First public release.
