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

53 New YAZ client features: Command completion and new commands:
54 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
55 Code provided by Jacob Poulsen.
57 New call oid_trav, that visits all registered OIDs via callback.
59 Function ZOOM_record_get now returns const char pointer rather than
60 void pointer. It saves a lot of type casts.
62 For YAZ client, command "auth" now allows you to set authentication
63 in IdPass style. It is enabled when three tokens are given - order
64 is user, group and password.
66 Fix memory leaks in MARC record handling for ZOOM.
68 New option for YAZ client, -k <kilobytes> that sets
69 maximum record size. Similar to -k option for generic frontend
72 More fixes for scan. Non-zero stepSize handled. OID's fixes.
74 Prefix query parser reports "fail" when bad attribute set is given.
76 Fix in MARC decoder. Proximity logging. Fix for attribute set
77 in scan handler for server. Patches by Shigeru Ishida.
79 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
82 Configure option --with-openssl=<dir> now works when a directory is
83 specified. Patch provided by Morten Bøgeskov.
85 New option for YAZ client, -u <auth>, that sets authentication.
87 ZOOM fix: error information was sometimes "missing", since error
88 was cleared/reset too when it shouldn't.
90 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
94 Scan for ZOOM API. New object ZOOM_scanset. New functions
95 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
98 New ZOOM function, ZOOM_connection_last_event, that returns type
99 of last event (such as "receive data", "send data", "apdu received",
102 New ZOOM option, schema, that specifies shema OID for retrieval.
104 New CCL feature. Qualifiers can be aliases for one or more
105 other qualifiers (if more than one is given, OR is used).
107 ZOOM uses named result sets if target supports it.
109 Two new YAZ client commands: . (dot, which sources a script of YAZ
110 client commands), and ! (to execute shell command.). Implemented
113 Working on Debian packages.
117 YAZ client enables named result sets only if target supports it.
119 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
121 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
122 with key="host" to get same result.
124 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
125 Function Z3950_resultset_record(s) returns references to records
126 "owned" by resultset. To become owner use Z3950_record_clone.
128 Function z_ext_record handles Extended Services. Thanks to
133 CCL Parser fix: ignore token comma when dealing with and-lists.
135 Documentation updates for COMSTACK.
137 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
138 Changed prototype Z3950_records. For some functions, int parameters
139 were changed to size_t.
141 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
144 New MARC decode/display function, marc_display_exl, which properly rejects
145 non-ISO2709 records. YAZ client uses it.
149 Fix bug: local attribute set wasn't set correctly in PQF strings.
153 * Old Z39.50 codecs no longer supported.
155 Added ZOOM C binding. See http://zoom.z3950.org/
157 Renamed states for COMSTACKs to avoid confusion with events.
159 Implemented cs_look and proper cs_rcvconnect.
161 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
163 Configure detects POSIX threads on OpenBSD.
165 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
166 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
168 When error is returned from present handler, non-surrogate diagnostic
169 is returned in present response (and fetch handler is no longer called).
171 * Minor adjustments to pquery parser (PQF). Token characters may be
172 escaped by using backslash (C-style).
174 PQF parser allows string attribute values to be specified. For @attr,
175 non-numeric characters after the equal-sign are treated as strings
176 (e.g. @attr 9=title).
178 CCL trunction character may be defined (@truncation in file)
180 * function zget_ExtendedServicesRequest sets waitAction to
181 waitIfPossible (was wait).
183 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
186 CCL operator names may be set in field definition files (CCL_bibset).
187 See ccl/bib1 for an example.
189 Fixes in ASN.1 compiler for C++ compatibility.
191 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
192 and "op_or" to avoid conflict with C++.
194 Fixed problem with GNU readline detection on Redhat 7.0.
196 Added step-size for Scan backend handler.
198 Fixed bug that made the frontend server crash when no attribute
199 set was specified for scan.
201 Front-end server automatically switches to original working directory
202 when installed as an NT service. Previously -w had to be specified to
205 Added extended attributes for retrieval module (data1), so that data1
206 records carry d1_readXML/SGML attributes. d1_read also supports
207 null-data rules ( <tag/>)
209 On UNIX when POSIX threads are available, a separate library libyazthread
210 is created. Programmers should link with that library and the yaz library
211 when using threads. The reason for the split was that some applications
212 on Linux, such as Apache, doesn't work well when using shared objects that
215 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
216 (or any frontend server) in SSL mode by specifying ssl: followed by
217 address. Only tested on UNIX.
219 Added feature for CCL module. Virtual structure s=al or s=ol generates
220 and-list and or-list respectively instead of phrase search.
224 * Added prefix "yaz_" for the functions log_init.., log_file.. and
225 log_mask_str. This was done to avoid name conflicts with other libraries
226 (such as other PHP extensions).
228 Added raw OID member for preferred record syntax (request_format_raw)
229 and returned record syntax (output_format_raw) for backend fetch method.
231 Config file yaz-config now accepts options so that it returns specific
232 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
234 Shared library support for UNIX using GNU libtool.
236 * Modified backend interface. Request/Response struct's replaced by
237 one read/write C struct. For example bend_fetchrequest and
238 bend_fetchresult have been replaced by single bend_fetch_rr struct.
239 Every handler - even search has to be registered in bend_init
240 handler. This means that the YAZ library no longer refers to
241 external functions and it makes it possible to make the whole
242 thing a single DLL/SO.
244 Added Segment handler for backend server.
246 Added Zmbol/Zebra administrative functions to YAZ client.
248 Threaded frontend server on UNIX (when POSIX Threads are available).
249 Starting the server with option -T enables multi-threading.
253 Added configure option --enable-comp/disable-comp to control use
254 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
255 located in sub directory asn.
257 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
258 in ${exec_prefix}/bin along with the other programs yaz-client and
261 GNU automake used to maintain makefiles.
265 Changed retrieval module so that we can load records with no abstract
266 syntax defined. Tagpaths in these records are fully composed of string
269 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
273 On UNIX, the generated makefile now supports a proper 'make install'.
274 The prefix can be set via GNU configure to set the install location
275 (default is /usr/local).
277 * YAZ programs client and ztest were renamed to yaz-client and
278 yaz-ztest to avoid conflicts when users install YAZ in "standard"
279 locations, such as /usr/bin,/usr/local/bin,etc.
281 * YAZ Header files were moved from include to include/yaz. YAZ Header
282 files are referred to as include <yaz/log.h> rather than <log.h>.
283 The YAZ include path (-I ..) is therefore the same as before. Programmers
284 should update their #include statements or use -Ipath/include/yaz
285 instead. The main motivation for doing this change is that YAZ header files
286 can be installed in "standard" locations /usr/include,/usr/local/include
287 without introducing conflicts, since ALL YAZ header files are stored
288 in subdirectory yaz (under /usr/include for example).
290 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
291 rather than project/workspace files. We switched because project files
292 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
295 Changed name of logging function, logf, to yaz_log, to prevent name
296 clash with some math-log functions. The YAZ header log.h defines logf
297 to yaz_log (#define) so there should be no incompatibilities by this
300 Added bend_start/bend_stop handlers for server. These handler are
301 called on start/stop of server. For windows they are called whenever
302 a service is started/stopped.
304 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
305 a fairly small ASN.1 compiler written in Tcl. The compiler is located
306 in util/yc.tcl. The auto-generated C code structures are, in a few
307 cases, incompatible with the old decoders. There are differences in the
308 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
309 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
310 The preprocessor variable ASN_COMPILED is defined when the compiled
311 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
312 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
313 wish to use the old encoders/decoders you can specify --disable-yc
316 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
317 version so that it supports both new - and old version of DB Update
319 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
320 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
321 change. The name parameter can be set to 0 in which no name is specified
322 for the construction. The macros odr_implicit and odr_explicit sets name
323 parameter to zero for the construction involved. New macros
324 odr_implicit_tag and odr_explicit_tag are similar to the others,
325 except that a name parameter is added. For programmers' that don't use
326 ODR they probably only need to change the call to z_APDU and z_External.
328 Added access control facility by interfacing the TCP wrapper library.
329 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
330 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
331 name of the daemon and enables the access control as specified in
332 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
334 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
335 den Dool <H.M.vdnDool@kub.nl>.
337 Added reference ID parameter to most functions in server API - refer
338 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
340 Changed name of ccl library to libccl.a (was ccl.a).
342 Fixed bug in decoder for Explain (Category TargetInfo).
344 Added support for GNU readline in client. Thanks to Jacob Poulsen
345 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
347 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
348 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
349 IMPLEMENTATION! This change was made to the development version before
350 the ZIG decided to retract the amendment. If any users MUST be
351 compatible with the original Update definition, PLEASE CONTACT US, and
352 we will include a separate definition corresponding to the old Update
353 ES. Note that because of the change to the ASN.1 of the
354 TaskPackageRecordStructure we cannot define a single structure that
355 will support both versions.
357 * Added const modifier to buffer parameter for some ODR/BER encoding
358 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
359 completeWAIS, odr_dumpBER.
361 Fixed bug in client.c which caused a crash when a scanResponse didn't
362 contain positionOfTerm.
364 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
365 * will cause an error in a client if a non-YAZ target sends both a
366 * list of Scan entries and non-surrogate diagnostics.
368 Retrieval module enhancements. Tag sets may be typed in the reference
369 to it. From the .abs-file the "tagset" directive takes a third optional
370 integer type for the tag set referenced. From a .tag-file the "include"
371 directive takes a third optional type as well. The old "type" directive
372 in the tag set itself is still recognized but acts as the default type
375 Backend interface change. Individual Scan terms returned from bend_scan
376 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
377 in include/backend.h.
379 Retrieval module enhancements. Multiple tag sets and attribute sets may
380 be specified in abstract syntax specs. Revised the error/warning for
381 logging messages reported by the retrieval module when reading the
384 Object Identifier system (oid_..) changed. The API is backwards
385 compatible but the oid-routines now allocates new OID's when needed.
386 Raw OID's may be specified in oid_getvalbyname.
388 YAZ now uses GNU configure to generate Makefile(s).
390 * Minor changes in some of the member names of DeleteResultSetRequest and
391 DeleteResultSetResponse. See include/proto.h.
393 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
394 and added member 'languages' in TargetInfo (which was missing).
396 Changed the way attribute sets are handled in the retrieval
397 module. These are now cached, just like the abstract syntaxes
400 Changed YAZ so that it links with compiled ASN.1.
402 Added Explain-schema definitions and mapping routines. The following
403 Explain categories have been implemented: AttributeDetails,
404 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
406 Fixed minor bug in Windows version of Server Library.
408 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
410 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
412 Added EXTERNAL: UNIverse Resource Report (non-standard).
414 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
415 ENUMERATED and SET OF.
417 * Added 'const' to some of the char pointer arguments for the
418 functions, data1_read_node, data1_getelementbytagname,
419 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
422 Fixed bug in data1_insert_taggeddata - the last_child member of
423 parent wasn't initialised.
425 * Changed data1_read_record and data1_read_node so that the supplied
426 "SGML"-buffer is read-only. In particular the resulting data1 - tree
427 doesn't refer to any parts of the "SGML"-buffer.
429 Fixed bug in server library (Windows version of statserv_remove).
431 * Changed code so that it compiles as C++. The type definition
432 of Odr_fun which is a member of Odr_arm was changed. The result is,
433 that an explicit typecast is needed for the fun pointer when
434 using Odr_arm - as in:
435 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
437 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
439 Implemented the new structured date and time definition as approved
440 by the ZIG. Added schemaId element to the specificTag in Espec-1
441 (also approved at the last ZIG). Thanks to RVDM.
443 Added some Object identifiers (RVDM).
445 Changed the Update Extended Service (RVDM).
447 Added command "refid" to client which specifies referenceId for
448 the following requests.
450 Implemented extended service handling for server. See ztest.c
451 for an example as well as backend.h. New handlers are registerd
454 * Changed interface for sort in server.
456 Added new members to statserv_options_block. It allows a server
457 to read options from another source than just the command line. Thanks
458 to Charles Woodfield.
460 * Changed definition of Z_Triple in file prt-grs.h - member boolean
461 renamed to zboolean. Some C++ compilers complained about the name.
463 Minor changes to gils.abs. Added index 's' (sort) on title
464 and date/time-last-modified.
468 Fixed bug in server library regarding inetd mode (-i). This bug
469 was introduced by release 1.4.
473 Added sort facility in client and backend server interface.
475 Fixed problem with dependencies in Makefile(s).
477 Fixed bugs for encoders/decoders of extended services and
480 Implemented sub-tree feature for schemas. Sub-trees are
481 referenced in *.abs-files. See explain.abs for an example
482 of the use of this feature.
484 Modified bib1.att; local attributes for ANY didn't include
485 ANY itself (only affects use of the retrieval module).
487 Fixed bug in plain SGML reader in function data1_read_node:
488 tags with prefix "var" was incorrectly interpreted as variants.
490 Added feature "sub-schemas" to enable references to - and definitions
491 of - group of elements.
493 * Removed member parent from type data1_element (in data1.h).
495 Implemented function odr_nullval() that returns the value of
498 * Removed member num_children from data1_node (in data1.h).
500 Made NT service interface part of the server library. The
501 function statserv_main uses the NT service when required and
502 calls the statserv_start / statserv_close routines.
504 Routine zget_SearchRequest and zget_PresentRequest fills
505 resultSetName/Id member with "default" instead of "Default".
507 Fixed memory leak in server. Request queue member wasn't freed.
509 Fixed nmem_exit so that memory is freed.
513 Revised the CCL parser utility to be thread safe.
515 Added function, oid_ent_to_oid, to replace the function
516 oid_getoidbyent, which is not thread safe.
518 * Added nmem_init and nmem_exit to initialize and release
519 NMEM resources. Function nmem_init should be called once in the
520 initial thread before NMEM/ODR is used. statserv.c and client.c
521 have been changed accordingly. The change was necessary to make
522 NMEM thread safe. The NMEM memory pool is shared amongst threads
523 in a process. Unix-based applications will still work fine without
526 Added NT Services interface for the the Z39.50 (statserv) Server.
527 Refer to the ztest.c source on the usage.
529 Windows 95/NT port using MSVC5.0. Project files are included in the
532 * Defined new 'global' handle for the retrieval (data1) system. The
533 new handled, data1_handle, describes the state of the data1 system.
534 This handle is passed as first argument to virtually all
535 data1 related routines. The functions data1_create and data1_destroy
536 creates and destroys a data1 handle respectively.
538 Added ODR encode stream member to all backend request structures
539 init, search, scan etc. This stream should be used to allocate all
540 memory used for the response when thread safe operation is needed.
542 Changed the comstack utility, cs_addstr, to be thread safe. The
543 returned hostname string returned by the function is now part the
546 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
547 function. The cs_straddr takes a COMSTACK handle as argument, so this
548 function must be used after cs_create and before bind/connect.
549 This function is thread safe.
551 Moved test server to 'ztest' directory - generic server code still
552 in 'server' directory.
554 Made prefix query (pquery.c) utility thread safe.
556 Added new function modifier YAZ_EXPORT to 'export' public DLL
557 functions when using windows (see include/yconfig.h).
559 Added definitions to the OID database (util/oid.c) (RVDM).
561 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
563 Added call to ccl_rpn_delete in client program.
565 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
566 release of RPN structure.
568 Added support for C++, headers uses extern "C" for public definitions.
569 With input from RVDM.
571 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
572 Thanks to Ronald van der Meer (RVDM).
574 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
576 Added support for private extensions to the OID database
577 (oid_setprivateoids()). Thanks to RVDM.
579 Added optional, physical ANY (key replication)
581 Fixed null-reference problem in GRS-1 output filter.
583 Proximity operator added to Prefix Query Format (PQF).
585 In test client command "base" accepts multiple databases.
587 Fixed bug in cs_close stack that caused trouble with WINSOCK.
591 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
593 Smallish bug-fixes in the new encoders/decoders (explain).
595 Bug fixed in DeleteRequest.
597 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
599 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
601 Added SOIF syntax (using private OID for now) to retrieval module and client.
603 Added Update extended service.
605 Added SearchResult-1 additional info structure.
607 Added optional CCL (ISO8777) interpreter as separate module. Available
610 --- 1.2 1996/6/10 (1st anniversary release)
612 Added Summary record syntax. Lightly tested.
614 Added OPAC record syntax. Untested.
616 Added ResourceReport service encoders/decoders. Untested.
618 Fixed bug in z_Unit - wrong tagging on unitSystem.
620 Fixed bug in the DiagRecs decoder.
622 Added options for max PDU size and session timeout to frontend-server.
624 Added documentation of query-language parsers and other supporting utilities.
626 [frontend-server] Added Attribute set to the bend_scanrequest API.
628 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
629 surrogate diagnostics were generated.
631 [retrieval] Allow multiple local values for attribute.
633 [retrieval] Allow multiple attributes per element in .abs files. index type.
635 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
639 Minor changes, mostly specific to Zebra's requirements (retrieval)
643 Repaired bug in frontend server when running multiple listening
644 endpoints in dynamic mode.
646 z_External() now won't break if a known, ASN.1 value comes encapsulated
647 in an octet-string. The value will pass through unmodified in an Odr_oct.
649 Added a bit of code to the demo client to decode & display
650 ASN.1-structured records represented in the octet-aligned branch of
651 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
653 Added z_ext_getentbyref() to the ASN module. Doc updated.
655 * Completed the SCAN definition in the ASN module. This may break SCAN
656 code based on older YAZ-versions at compile-time. The fix is easy -
659 * Added 'displayTerm' and OtherInformation to the TermInfo structure
660 under the SCAN definition. Remember to initialize this, server-people.
662 Comstack should now support the WAIS protocol in TCP/IP mode. Note
663 that this does not extend to ODR and ASN.
665 Comstack allows insertion of established socket (primarily for
666 inetd-operation of servers). Doc updated.
668 Front-end server can now start from the inetd in TCP mode. Doc
675 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
676 the rank and record number.
678 Adjustments to the frontend server.
680 Fixed diagnostic BER dumper. It ignored the file argument.
684 Various changes to retrieval module.
686 Changed the union discriminators of the protocol files from enums to
687 ints paired with #defines.
689 *Changed oident.class to oident.oclass to avoid a reserved word in C++
692 *Changed operator in the RPN structure to 'roperator', again to avoid a
695 Fixed problems in Explain decoders/encoders.
699 Memory bug in log module fixed.
703 Occasional malloc() of 0 bytes fixed in d1_espec.c.
705 Bug in Explain DatabaseInfo module fixed.
707 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
711 The shift to v1.0 signals that we now consider the *core* functionality
712 of YAZ reasonably stable (the core being more or less equivalent to
713 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
714 tested (Explain not at all - though that will happen soonish).
716 Minor changes to code to support Windows port.
718 Various minor changes after we're getting to use GRS-1 & co. more.
720 Added Espec-1 format.
722 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
723 of the protocol and it cannot be selected when encoding (maps into 'string'
724 when decoding). Needed to talk to some servers.
726 Demo client can request simple element set names.
728 Added Diagnostic Format encoders/decoders.
730 Added simple Close handling to frontend server (no hooks for resource
731 reporting yet), and demonstration client.
733 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
737 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
738 handled incorrectly when records were requested in the searchResponse. This
739 will only affect you if you use the frontend-server.
741 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
742 Test-client will ask for and print GRS1. Ztest will return dummy records
745 Added Explain encoders/decoders to the service-level API. Untested.
747 Added Extended Services: Item Order encoders and decoders to the Service-
748 level API. Untested. We could use a recent copy of the pertinent bits
749 of the ILL protocol to add those bits.
751 Added diagnostic format 1 encoders/decoders to the service-level API.
754 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
755 odr_cons.c, which causes a more correct output.
757 Fixed handling of searchRequest in frontend server. NextResultSetPosition
758 was always set to 0 when no records were requested in the searchRequest.
760 * Added better external-handling. This shouldn't harm old code that
761 *encodes* externals. It can break code that looks for a
762 'single-ASN1-type' representation, since those types that are known
763 are now decoded immediately. Look at the SUTRS sample code in
764 seshigh.c and client.c. Documentation updated.
766 Handling of structured records in bend_fetchresponse. Length -1 marks
767 structured record, type is deduced from format field.
770 Fairly quick maintenance release to add SUTRS support.
772 Fixed handling of SUTRS records in the demonstration client.
774 * Added format field to the bend_fetchrequest and bend_fetchresponce
775 structures of the backend API (frontend server). When the record is
776 returned, the value of the format field is mapped to an OID. The
777 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
778 of the record. The special value VAL_NONE in the bend_request means
779 that no specific format was requested by the client. Documentation
780 updated accordingly. Test server (ztest) will return a fixed dummy
781 SUTRS record if your client requests SUTRS.
783 Documentation updated accordingly.
785 You can now set external libraries and RANLIB support in the top-level
789 First public release.
