1 Possible compatibility problems with earlier versions marked with '*'.
6 Attributes from multiple CCL fields may be OR'ed rather than merged
7 using directive "@field or". Fields are still merged by default -
8 equivalent to "@field merge".
10 XML reader for data1 (EXPAT).
12 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
15 Fixed bug in zget for parameter ExtendedServicesResponse.
21 Added PQF feature: '@attr type=value' may be written as '@type=value'.
23 Client displays USR.1:SearchResult-1 (hits per term).
25 Additional Search Info for search in Generic Frontend Server.
27 Fixed CCL parsing of "field=s".
29 WIN32 installer - using the excellent NSIS software from nullsoft.
31 Fixed CCL parsing of "field = - <number>".
33 Added function yaz_marc_decode that decodes MARC for line mode
34 display or XML (similar to that used by JZKit).
36 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
37 Z39.50. But ISO/ILL was, however.
39 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
40 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

47 New YAZ client features: Command completion and new commands:
48 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
49 Code provided by Jacob Poulsen.
51 New call oid_trav, that visits all registered OIDs via callback.
53 Function ZOOM_record_get now returns const char pointer rather than
54 void pointer. It saves a lot of type casts.
56 For YAZ client, command "auth" now allows you to set authentication
57 in IdPass style. It is enabled when three tokens are given - order
58 is user, group and password.
60 Fix memory leaks in MARC record handling for ZOOM.
62 New option for YAZ client, -k <kilobytes> that sets
63 maximum record size. Similar to -k option for generic frontend
66 More fixes for scan. Non-zero stepSize handled. OID's fixes.
68 Prefix query parser reports "fail" when bad attribute set is given.
70 Fix in MARC decoder. Proximity logging. Fix for attribute set
71 in scan handler for server. Patches by Shigeru Ishida.
73 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
76 Configure option --with-openssl=<dir> now works when a directory is
77 specified. Patch provided by Morten Bøgeskov.
79 New option for YAZ client, -u <auth>, that sets authentication.
81 ZOOM fix: error information was sometimes "missing", since error
82 was cleared/reset too when it shouldn't.
84 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
88 Scan for ZOOM API. New object ZOOM_scanset. New functions
89 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
92 New ZOOM function, ZOOM_connection_last_event, that returns type
93 of last event (such as "receive data", "send data", "apdu received",
96 New ZOOM option, schema, that specifies shema OID for retrieval.
98 New CCL feature. Qualifiers can be aliases for one or more
99 other qualifiers (if more than one is given, OR is used).
101 ZOOM uses named result sets if target supports it.
103 Two new YAZ client commands: . (dot, which sources a script of YAZ
104 client commands), and ! (to execute shell command.). Implemented
107 Working on Debian packages.
111 YAZ client enables named result sets only if target supports it.
113 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
115 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
116 with key="host" to get same result.
118 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
119 Function Z3950_resultset_record(s) returns references to records
120 "owned" by resultset. To become owner use Z3950_record_clone.
122 Function z_ext_record handles Extended Services. Thanks to
127 CCL Parser fix: ignore token comma when dealing with and-lists.
129 Documentation updates for COMSTACK.
131 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
132 Changed prototype Z3950_records. For some functions, int parameters
133 were changed to size_t.
135 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
138 New MARC decode/display function, marc_display_exl, which properly rejects
139 non-ISO2709 records. YAZ client uses it.
143 Fix bug: local attribute set wasn't set correctly in PQF strings.
147 * Old Z39.50 codecs no longer supported.
149 Added ZOOM C binding. See http://zoom.z3950.org/
151 Renamed states for COMSTACKs to avoid confusion with events.
153 Implemented cs_look and proper cs_rcvconnect.
155 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
157 Configure detects POSIX threads on OpenBSD.
159 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
160 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
162 When error is returned from present handler, non-surrogate diagnostic
163 is returned in present response (and fetch handler is no longer called).
165 * Minor adjustments to pquery parser (PQF). Token characters may be
166 escaped by using backslash (C-style).
168 PQF parser allows string attribute values to be specified. For @attr,
169 non-numeric characters after the equal-sign are treated as strings
170 (e.g. @attr 9=title).
172 CCL trunction character may be defined (@truncation in file)
174 * function zget_ExtendedServicesRequest sets waitAction to
175 waitIfPossible (was wait).
177 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
180 CCL operator names may be set in field definition files (CCL_bibset).
181 See ccl/bib1 for an example.
183 Fixes in ASN.1 compiler for C++ compatibility.
185 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
186 and "op_or" to avoid conflict with C++.
188 Fixed problem with GNU readline detection on Redhat 7.0.
190 Added step-size for Scan backend handler.
192 Fixed bug that made the frontend server crash when no attribute
193 set was specified for scan.
195 Front-end server automatically switches to original working directory
196 when installed as an NT service. Previously -w had to be specified to
199 Added extended attributes for retrieval module (data1), so that data1
200 records carry d1_readXML/SGML attributes. d1_read also supports
201 null-data rules ( <tag/>)
203 On UNIX when POSIX threads are available, a separate library libyazthread
204 is created. Programmers should link with that library and the yaz library
205 when using threads. The reason for the split was that some applications
206 on Linux, such as Apache, doesn't work well when using shared objects that
209 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
210 (or any frontend server) in SSL mode by specifying ssl: followed by
211 address. Only tested on UNIX.
213 Added feature for CCL module. Virtual structure s=al or s=ol generates
214 and-list and or-list respectively instead of phrase search.
218 * Added prefix "yaz_" for the functions log_init.., log_file.. and
219 log_mask_str. This was done to avoid name conflicts with other libraries
220 (such as other PHP extensions).
222 Added raw OID member for preferred record syntax (request_format_raw)
223 and returned record syntax (output_format_raw) for backend fetch method.
225 Config file yaz-config now accepts options so that it returns specific
226 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
228 Shared library support for UNIX using GNU libtool.
230 * Modified backend interface. Request/Response struct's replaced by
231 one read/write C struct. For example bend_fetchrequest and
232 bend_fetchresult have been replaced by single bend_fetch_rr struct.
233 Every handler - even search has to be registered in bend_init
234 handler. This means that the YAZ library no longer refers to
235 external functions and it makes it possible to make the whole
236 thing a single DLL/SO.
238 Added Segment handler for backend server.
240 Added Zmbol/Zebra administrative functions to YAZ client.
242 Threaded frontend server on UNIX (when POSIX Threads are available).
243 Starting the server with option -T enables multi-threading.
247 Added configure option --enable-comp/disable-comp to control use
248 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
249 located in sub directory asn.
251 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
252 in ${exec_prefix}/bin along with the other programs yaz-client and
255 GNU automake used to maintain makefiles.
259 Changed retrieval module so that we can load records with no abstract
260 syntax defined. Tagpaths in these records are fully composed of string
263 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
267 On UNIX, the generated makefile now supports a proper 'make install'.
268 The prefix can be set via GNU configure to set the install location
269 (default is /usr/local).
271 * YAZ programs client and ztest were renamed to yaz-client and
272 yaz-ztest to avoid conflicts when users install YAZ in "standard"
273 locations, such as /usr/bin,/usr/local/bin,etc.
275 * YAZ Header files were moved from include to include/yaz. YAZ Header
276 files are referred to as include <yaz/log.h> rather than <log.h>.
277 The YAZ include path (-I ..) is therefore the same as before. Programmers
278 should update their #include statements or use -Ipath/include/yaz
279 instead. The main motivation for doing this change is that YAZ header files
280 can be installed in "standard" locations /usr/include,/usr/local/include
281 without introducing conflicts, since ALL YAZ header files are stored
282 in subdirectory yaz (under /usr/include for example).
284 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
285 rather than project/workspace files. We switched because project files
286 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
289 Changed name of logging function, logf, to yaz_log, to prevent name
290 clash with some math-log functions. The YAZ header log.h defines logf
291 to yaz_log (#define) so there should be no incompatibilities by this
294 Added bend_start/bend_stop handlers for server. These handler are
295 called on start/stop of server. For windows they are called whenever
296 a service is started/stopped.
298 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
299 a fairly small ASN.1 compiler written in Tcl. The compiler is located
300 in util/yc.tcl. The auto-generated C code structures are, in a few
301 cases, incompatible with the old decoders. There are differences in the
302 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
303 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
304 The preprocessor variable ASN_COMPILED is defined when the compiled
305 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
306 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
307 wish to use the old encoders/decoders you can specify --disable-yc
310 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
311 version so that it supports both new - and old version of DB Update
313 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
314 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
315 change. The name parameter can be set to 0 in which no name is specified
316 for the construction. The macros odr_implicit and odr_explicit sets name
317 parameter to zero for the construction involved. New macros
318 odr_implicit_tag and odr_explicit_tag are similar to the others,
319 except that a name parameter is added. For programmers' that don't use
320 ODR they probably only need to change the call to z_APDU and z_External.
322 Added access control facility by interfacing the TCP wrapper library.
323 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
324 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
325 name of the daemon and enables the access control as specified in
326 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
328 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
329 den Dool <H.M.vdnDool@kub.nl>.
331 Added reference ID parameter to most functions in server API - refer
332 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
334 Changed name of ccl library to libccl.a (was ccl.a).
336 Fixed bug in decoder for Explain (Category TargetInfo).
338 Added support for GNU readline in client. Thanks to Jacob Poulsen
339 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
341 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
342 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
343 IMPLEMENTATION! This change was made to the development version before
344 the ZIG decided to retract the amendment. If any users MUST be
345 compatible with the original Update definition, PLEASE CONTACT US, and
346 we will include a separate definition corresponding to the old Update
347 ES. Note that because of the change to the ASN.1 of the
348 TaskPackageRecordStructure we cannot define a single structure that
349 will support both versions.
351 * Added const modifier to buffer parameter for some ODR/BER encoding
352 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
353 completeWAIS, odr_dumpBER.
355 Fixed bug in client.c which caused a crash when a scanResponse didn't
356 contain positionOfTerm.
358 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
359 * will cause an error in a client if a non-YAZ target sends both a
360 * list of Scan entries and non-surrogate diagnostics.
362 Retrieval module enhancements. Tag sets may be typed in the reference
363 to it. From the .abs-file the "tagset" directive takes a third optional
364 integer type for the tag set referenced. From a .tag-file the "include"
365 directive takes a third optional type as well. The old "type" directive
366 in the tag set itself is still recognized but acts as the default type
369 Backend interface change. Individual Scan terms returned from bend_scan
370 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
371 in include/backend.h.
373 Retrieval module enhancements. Multiple tag sets and attribute sets may
374 be specified in abstract syntax specs. Revised the error/warning for
375 logging messages reported by the retrieval module when reading the
378 Object Identifier system (oid_..) changed. The API is backwards
379 compatible but the oid-routines now allocates new OID's when needed.
380 Raw OID's may be specified in oid_getvalbyname.
382 YAZ now uses GNU configure to generate Makefile(s).
384 * Minor changes in some of the member names of DeleteResultSetRequest and
385 DeleteResultSetResponse. See include/proto.h.
387 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
388 and added member 'languages' in TargetInfo (which was missing).
390 Changed the way attribute sets are handled in the retrieval
391 module. These are now cached, just like the abstract syntaxes
394 Changed YAZ so that it links with compiled ASN.1.
396 Added Explain-schema definitions and mapping routines. The following
397 Explain categories have been implemented: AttributeDetails,
398 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
400 Fixed minor bug in Windows version of Server Library.
402 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
404 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
406 Added EXTERNAL: UNIverse Resource Report (non-standard).
408 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
409 ENUMERATED and SET OF.
411 * Added 'const' to some of the char pointer arguments for the
412 functions, data1_read_node, data1_getelementbytagname,
413 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
416 Fixed bug in data1_insert_taggeddata - the last_child member of
417 parent wasn't initialised.
419 * Changed data1_read_record and data1_read_node so that the supplied
420 "SGML"-buffer is read-only. In particular the resulting data1 - tree
421 doesn't refer to any parts of the "SGML"-buffer.
423 Fixed bug in server library (Windows version of statserv_remove).
425 * Changed code so that it compiles as C++. The type definition
426 of Odr_fun which is a member of Odr_arm was changed. The result is,
427 that an explicit typecast is needed for the fun pointer when
428 using Odr_arm - as in:
429 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
431 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
433 Implemented the new structured date and time definition as approved
434 by the ZIG. Added schemaId element to the specificTag in Espec-1
435 (also approved at the last ZIG). Thanks to RVDM.
437 Added some Object identifiers (RVDM).
439 Changed the Update Extended Service (RVDM).
441 Added command "refid" to client which specifies referenceId for
442 the following requests.
444 Implemented extended service handling for server. See ztest.c
445 for an example as well as backend.h. New handlers are registerd
448 * Changed interface for sort in server.
450 Added new members to statserv_options_block. It allows a server
451 to read options from another source than just the command line. Thanks
452 to Charles Woodfield.
454 * Changed definition of Z_Triple in file prt-grs.h - member boolean
455 renamed to zboolean. Some C++ compilers complained about the name.
457 Minor changes to gils.abs. Added index 's' (sort) on title
458 and date/time-last-modified.
462 Fixed bug in server library regarding inetd mode (-i). This bug
463 was introduced by release 1.4.
467 Added sort facility in client and backend server interface.
469 Fixed problem with dependencies in Makefile(s).
471 Fixed bugs for encoders/decoders of extended services and
474 Implemented sub-tree feature for schemas. Sub-trees are
475 referenced in *.abs-files. See explain.abs for an example
476 of the use of this feature.
478 Modified bib1.att; local attributes for ANY didn't include
479 ANY itself (only affects use of the retrieval module).
481 Fixed bug in plain SGML reader in function data1_read_node:
482 tags with prefix "var" was incorrectly interpreted as variants.
484 Added feature "sub-schemas" to enable references to - and definitions
485 of - group of elements.
487 * Removed member parent from type data1_element (in data1.h).
489 Implemented function odr_nullval() that returns the value of
492 * Removed member num_children from data1_node (in data1.h).
494 Made NT service interface part of the server library. The
495 function statserv_main uses the NT service when required and
496 calls the statserv_start / statserv_close routines.
498 Routine zget_SearchRequest and zget_PresentRequest fills
499 resultSetName/Id member with "default" instead of "Default".
501 Fixed memory leak in server. Request queue member wasn't freed.
503 Fixed nmem_exit so that memory is freed.
507 Revised the CCL parser utility to be thread safe.
509 Added function, oid_ent_to_oid, to replace the function
510 oid_getoidbyent, which is not thread safe.
512 * Added nmem_init and nmem_exit to initialize and release
513 NMEM resources. Function nmem_init should be called once in the
514 initial thread before NMEM/ODR is used. statserv.c and client.c
515 have been changed accordingly. The change was necessary to make
516 NMEM thread safe. The NMEM memory pool is shared amongst threads
517 in a process. Unix-based applications will still work fine without
520 Added NT Services interface for the the Z39.50 (statserv) Server.
521 Refer to the ztest.c source on the usage.
523 Windows 95/NT port using MSVC5.0. Project files are included in the
526 * Defined new 'global' handle for the retrieval (data1) system. The
527 new handled, data1_handle, describes the state of the data1 system.
528 This handle is passed as first argument to virtually all
529 data1 related routines. The functions data1_create and data1_destroy
530 creates and destroys a data1 handle respectively.
532 Added ODR encode stream member to all backend request structures
533 init, search, scan etc. This stream should be used to allocate all
534 memory used for the response when thread safe operation is needed.
536 Changed the comstack utility, cs_addstr, to be thread safe. The
537 returned hostname string returned by the function is now part the
540 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
541 function. The cs_straddr takes a COMSTACK handle as argument, so this
542 function must be used after cs_create and before bind/connect.
543 This function is thread safe.
545 Moved test server to 'ztest' directory - generic server code still
546 in 'server' directory.
548 Made prefix query (pquery.c) utility thread safe.
550 Added new function modifier YAZ_EXPORT to 'export' public DLL
551 functions when using windows (see include/yconfig.h).
553 Added definitions to the OID database (util/oid.c) (RVDM).
555 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
557 Added call to ccl_rpn_delete in client program.
559 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
560 release of RPN structure.
562 Added support for C++, headers uses extern "C" for public definitions.
563 With input from RVDM.
565 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
566 Thanks to Ronald van der Meer (RVDM).
568 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
570 Added support for private extensions to the OID database
571 (oid_setprivateoids()). Thanks to RVDM.
573 Added optional, physical ANY (key replication)
575 Fixed null-reference problem in GRS-1 output filter.
577 Proximity operator added to Prefix Query Format (PQF).
579 In test client command "base" accepts multiple databases.
581 Fixed bug in cs_close stack that caused trouble with WINSOCK.
585 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
587 Smallish bug-fixes in the new encoders/decoders (explain).
589 Bug fixed in DeleteRequest.
591 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
593 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
595 Added SOIF syntax (using private OID for now) to retrieval module and client.
597 Added Update extended service.
599 Added SearchResult-1 additional info structure.
601 Added optional CCL (ISO8777) interpreter as separate module. Available
604 --- 1.2 1996/6/10 (1st anniversary release)
606 Added Summary record syntax. Lightly tested.
608 Added OPAC record syntax. Untested.
610 Added ResourceReport service encoders/decoders. Untested.
612 Fixed bug in z_Unit - wrong tagging on unitSystem.
614 Fixed bug in the DiagRecs decoder.
616 Added options for max PDU size and session timeout to frontend-server.
618 Added documentation of query-language parsers and other supporting utilities.
620 [frontend-server] Added Attribute set to the bend_scanrequest API.
622 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
623 surrogate diagnostics were generated.
625 [retrieval] Allow multiple local values for attribute.
627 [retrieval] Allow multiple attributes per element in .abs files. index type.
629 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
633 Minor changes, mostly specific to Zebra's requirements (retrieval)
637 Repaired bug in frontend server when running multiple listening
638 endpoints in dynamic mode.
640 z_External() now won't break if a known, ASN.1 value comes encapsulated
641 in an octet-string. The value will pass through unmodified in an Odr_oct.
643 Added a bit of code to the demo client to decode & display
644 ASN.1-structured records represented in the octet-aligned branch of
645 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
647 Added z_ext_getentbyref() to the ASN module. Doc updated.
649 * Completed the SCAN definition in the ASN module. This may break SCAN
650 code based on older YAZ-versions at compile-time. The fix is easy -
653 * Added 'displayTerm' and OtherInformation to the TermInfo structure
654 under the SCAN definition. Remember to initialize this, server-people.
656 Comstack should now support the WAIS protocol in TCP/IP mode. Note
657 that this does not extend to ODR and ASN.
659 Comstack allows insertion of established socket (primarily for
660 inetd-operation of servers). Doc updated.
662 Front-end server can now start from the inetd in TCP mode. Doc
669 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
670 the rank and record number.
672 Adjustments to the frontend server.
674 Fixed diagnostic BER dumper. It ignored the file argument.
678 Various changes to retrieval module.
680 Changed the union discriminators of the protocol files from enums to
681 ints paired with #defines.
683 *Changed oident.class to oident.oclass to avoid a reserved word in C++
686 *Changed operator in the RPN structure to 'roperator', again to avoid a
689 Fixed problems in Explain decoders/encoders.
693 Memory bug in log module fixed.
697 Occasional malloc() of 0 bytes fixed in d1_espec.c.
699 Bug in Explain DatabaseInfo module fixed.
701 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
705 The shift to v1.0 signals that we now consider the *core* functionality
706 of YAZ reasonably stable (the core being more or less equivalent to
707 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
708 tested (Explain not at all - though that will happen soonish).
710 Minor changes to code to support Windows port.
712 Various minor changes after we're getting to use GRS-1 & co. more.
714 Added Espec-1 format.
716 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
717 of the protocol and it cannot be selected when encoding (maps into 'string'
718 when decoding). Needed to talk to some servers.
720 Demo client can request simple element set names.
722 Added Diagnostic Format encoders/decoders.
724 Added simple Close handling to frontend server (no hooks for resource
725 reporting yet), and demonstration client.
727 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
731 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
732 handled incorrectly when records were requested in the searchResponse. This
733 will only affect you if you use the frontend-server.
735 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
736 Test-client will ask for and print GRS1. Ztest will return dummy records
739 Added Explain encoders/decoders to the service-level API. Untested.
741 Added Extended Services: Item Order encoders and decoders to the Service-
742 level API. Untested. We could use a recent copy of the pertinent bits
743 of the ILL protocol to add those bits.
745 Added diagnostic format 1 encoders/decoders to the service-level API.
748 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
749 odr_cons.c, which causes a more correct output.
751 Fixed handling of searchRequest in frontend server. NextResultSetPosition
752 was always set to 0 when no records were requested in the searchRequest.
754 * Added better external-handling. This shouldn't harm old code that
755 *encodes* externals. It can break code that looks for a
756 'single-ASN1-type' representation, since those types that are known
757 are now decoded immediately. Look at the SUTRS sample code in
758 seshigh.c and client.c. Documentation updated.
760 Handling of structured records in bend_fetchresponse. Length -1 marks
761 structured record, type is deduced from format field.
764 Fairly quick maintenance release to add SUTRS support.
766 Fixed handling of SUTRS records in the demonstration client.
768 * Added format field to the bend_fetchrequest and bend_fetchresponce
769 structures of the backend API (frontend server). When the record is
770 returned, the value of the format field is mapped to an OID. The
771 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
772 of the record. The special value VAL_NONE in the bend_request means
773 that no specific format was requested by the client. Documentation
774 updated accordingly. Test server (ztest) will return a fixed dummy
775 SUTRS record if your client requests SUTRS.
777 Documentation updated accordingly.
779 You can now set external libraries and RANLIB support in the top-level
783 First public release.
