1 Possible compatibility problems with earlier versions marked with '*'.
8 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
9 that they can be used directly from Visual Basic. You must recompile
10 your windows APP if you're using ZOOM.
12 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
13 Commands "lang" and "charset" sets language and character set respectively.
14 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
15 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
17 Attributes from multiple CCL fields may be OR'ed rather than merged
18 using directive "@field or". Fields are still merged by default -
19 equivalent to "@field merge".
21 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
24 Fixed bug in zget for parameter ExtendedServicesResponse.
30 Added PQF feature: '@attr type=value' may be written as '@type=value'.
32 Client displays USR.1:SearchResult-1 (hits per term).
34 Additional Search Info for search in Generic Frontend Server.
36 Fixed CCL parsing of "field=s".
38 WIN32 installer - using the excellent NSIS software from nullsoft.
40 Fixed CCL parsing of "field = - <number>".
42 Added function yaz_marc_decode that decodes MARC for line mode
43 display or XML (similar to that used by JZKit).
45 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
46 Z39.50. But ISO/ILL was, however.
48 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
49 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

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