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

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