1 Possible compatibility problems with earlier versions marked with '*'.
5 Solaris recv sometimes returns errno == ENOENT. It is treated as
6 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
8 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
9 both client and server. Code by Morten Bøgeskov.
13 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
14 that they can be used directly from Visual Basic. You must recompile
15 your windows APP if you're using ZOOM.
17 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
18 Commands "lang" and "charset" sets language and character set respectively.
19 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
20 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
22 Attributes from multiple CCL fields may be OR'ed rather than merged
23 using directive "@field or". Fields are still merged by default -
24 equivalent to "@field merge".
26 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
29 Fixed bug in zget for parameter ExtendedServicesResponse.
35 Added PQF feature: '@attr type=value' may be written as '@type=value'.
37 Client displays USR.1:SearchResult-1 (hits per term).
39 Additional Search Info for search in Generic Frontend Server.
41 Fixed CCL parsing of "field=s".
43 WIN32 installer - using the excellent NSIS software from nullsoft.
45 Fixed CCL parsing of "field = - <number>".
47 Added function yaz_marc_decode that decodes MARC for line mode
48 display or XML (similar to that used by JZKit).
50 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
51 Z39.50. But ISO/ILL was, however.
53 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
54 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

61 New YAZ client features: Command completion and new commands:
62 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
63 Code provided by Jacob Poulsen.
65 New call oid_trav, that visits all registered OIDs via callback.
67 Function ZOOM_record_get now returns const char pointer rather than
68 void pointer. It saves a lot of type casts.
70 For YAZ client, command "auth" now allows you to set authentication
71 in IdPass style. It is enabled when three tokens are given - order
72 is user, group and password.
74 Fix memory leaks in MARC record handling for ZOOM.
76 New option for YAZ client, -k <kilobytes> that sets
77 maximum record size. Similar to -k option for generic frontend
80 More fixes for scan. Non-zero stepSize handled. OID's fixes.
82 Prefix query parser reports "fail" when bad attribute set is given.
84 Fix in MARC decoder. Proximity logging. Fix for attribute set
85 in scan handler for server. Patches by Shigeru Ishida.
87 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
90 Configure option --with-openssl=<dir> now works when a directory is
91 specified. Patch provided by Morten Bøgeskov.
93 New option for YAZ client, -u <auth>, that sets authentication.
95 ZOOM fix: error information was sometimes "missing", since error
96 was cleared/reset too when it shouldn't.
98 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
102 Scan for ZOOM API. New object ZOOM_scanset. New functions
103 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
104 ZOOM_scanset_destroy.
106 New ZOOM function, ZOOM_connection_last_event, that returns type
107 of last event (such as "receive data", "send data", "apdu received",
110 New ZOOM option, schema, that specifies shema OID for retrieval.
112 New CCL feature. Qualifiers can be aliases for one or more
113 other qualifiers (if more than one is given, OR is used).
115 ZOOM uses named result sets if target supports it.
117 Two new YAZ client commands: . (dot, which sources a script of YAZ
118 client commands), and ! (to execute shell command.). Implemented
121 Working on Debian packages.
125 YAZ client enables named result sets only if target supports it.
127 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
129 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
130 with key="host" to get same result.
132 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
133 Function Z3950_resultset_record(s) returns references to records
134 "owned" by resultset. To become owner use Z3950_record_clone.
136 Function z_ext_record handles Extended Services. Thanks to
141 CCL Parser fix: ignore token comma when dealing with and-lists.
143 Documentation updates for COMSTACK.
145 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
146 Changed prototype Z3950_records. For some functions, int parameters
147 were changed to size_t.
149 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
152 New MARC decode/display function, marc_display_exl, which properly rejects
153 non-ISO2709 records. YAZ client uses it.
157 Fix bug: local attribute set wasn't set correctly in PQF strings.
161 * Old Z39.50 codecs no longer supported.
163 Added ZOOM C binding. See http://zoom.z3950.org/
165 Renamed states for COMSTACKs to avoid confusion with events.
167 Implemented cs_look and proper cs_rcvconnect.
169 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
171 Configure detects POSIX threads on OpenBSD.
173 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
174 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
176 When error is returned from present handler, non-surrogate diagnostic
177 is returned in present response (and fetch handler is no longer called).
179 * Minor adjustments to pquery parser (PQF). Token characters may be
180 escaped by using backslash (C-style).
182 PQF parser allows string attribute values to be specified. For @attr,
183 non-numeric characters after the equal-sign are treated as strings
184 (e.g. @attr 9=title).
186 CCL trunction character may be defined (@truncation in file)
188 * function zget_ExtendedServicesRequest sets waitAction to
189 waitIfPossible (was wait).
191 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
194 CCL operator names may be set in field definition files (CCL_bibset).
195 See ccl/bib1 for an example.
197 Fixes in ASN.1 compiler for C++ compatibility.
199 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
200 and "op_or" to avoid conflict with C++.
202 Fixed problem with GNU readline detection on Redhat 7.0.
204 Added step-size for Scan backend handler.
206 Fixed bug that made the frontend server crash when no attribute
207 set was specified for scan.
209 Front-end server automatically switches to original working directory
210 when installed as an NT service. Previously -w had to be specified to
213 Added extended attributes for retrieval module (data1), so that data1
214 records carry d1_readXML/SGML attributes. d1_read also supports
215 null-data rules ( <tag/>)
217 On UNIX when POSIX threads are available, a separate library libyazthread
218 is created. Programmers should link with that library and the yaz library
219 when using threads. The reason for the split was that some applications
220 on Linux, such as Apache, doesn't work well when using shared objects that
223 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
224 (or any frontend server) in SSL mode by specifying ssl: followed by
225 address. Only tested on UNIX.
227 Added feature for CCL module. Virtual structure s=al or s=ol generates
228 and-list and or-list respectively instead of phrase search.
232 * Added prefix "yaz_" for the functions log_init.., log_file.. and
233 log_mask_str. This was done to avoid name conflicts with other libraries
234 (such as other PHP extensions).
236 Added raw OID member for preferred record syntax (request_format_raw)
237 and returned record syntax (output_format_raw) for backend fetch method.
239 Config file yaz-config now accepts options so that it returns specific
240 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
242 Shared library support for UNIX using GNU libtool.
244 * Modified backend interface. Request/Response struct's replaced by
245 one read/write C struct. For example bend_fetchrequest and
246 bend_fetchresult have been replaced by single bend_fetch_rr struct.
247 Every handler - even search has to be registered in bend_init
248 handler. This means that the YAZ library no longer refers to
249 external functions and it makes it possible to make the whole
250 thing a single DLL/SO.
252 Added Segment handler for backend server.
254 Added Zmbol/Zebra administrative functions to YAZ client.
256 Threaded frontend server on UNIX (when POSIX Threads are available).
257 Starting the server with option -T enables multi-threading.
261 Added configure option --enable-comp/disable-comp to control use
262 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
263 located in sub directory asn.
265 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
266 in ${exec_prefix}/bin along with the other programs yaz-client and
269 GNU automake used to maintain makefiles.
273 Changed retrieval module so that we can load records with no abstract
274 syntax defined. Tagpaths in these records are fully composed of string
277 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
281 On UNIX, the generated makefile now supports a proper 'make install'.
282 The prefix can be set via GNU configure to set the install location
283 (default is /usr/local).
285 * YAZ programs client and ztest were renamed to yaz-client and
286 yaz-ztest to avoid conflicts when users install YAZ in "standard"
287 locations, such as /usr/bin,/usr/local/bin,etc.
289 * YAZ Header files were moved from include to include/yaz. YAZ Header
290 files are referred to as include <yaz/log.h> rather than <log.h>.
291 The YAZ include path (-I ..) is therefore the same as before. Programmers
292 should update their #include statements or use -Ipath/include/yaz
293 instead. The main motivation for doing this change is that YAZ header files
294 can be installed in "standard" locations /usr/include,/usr/local/include
295 without introducing conflicts, since ALL YAZ header files are stored
296 in subdirectory yaz (under /usr/include for example).
298 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
299 rather than project/workspace files. We switched because project files
300 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
303 Changed name of logging function, logf, to yaz_log, to prevent name
304 clash with some math-log functions. The YAZ header log.h defines logf
305 to yaz_log (#define) so there should be no incompatibilities by this
308 Added bend_start/bend_stop handlers for server. These handler are
309 called on start/stop of server. For windows they are called whenever
310 a service is started/stopped.
312 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
313 a fairly small ASN.1 compiler written in Tcl. The compiler is located
314 in util/yc.tcl. The auto-generated C code structures are, in a few
315 cases, incompatible with the old decoders. There are differences in the
316 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
317 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
318 The preprocessor variable ASN_COMPILED is defined when the compiled
319 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
320 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
321 wish to use the old encoders/decoders you can specify --disable-yc
324 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
325 version so that it supports both new - and old version of DB Update
327 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
328 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
329 change. The name parameter can be set to 0 in which no name is specified
330 for the construction. The macros odr_implicit and odr_explicit sets name
331 parameter to zero for the construction involved. New macros
332 odr_implicit_tag and odr_explicit_tag are similar to the others,
333 except that a name parameter is added. For programmers' that don't use
334 ODR they probably only need to change the call to z_APDU and z_External.
336 Added access control facility by interfacing the TCP wrapper library.
337 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
338 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
339 name of the daemon and enables the access control as specified in
340 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
342 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
343 den Dool <H.M.vdnDool@kub.nl>.
345 Added reference ID parameter to most functions in server API - refer
346 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
348 Changed name of ccl library to libccl.a (was ccl.a).
350 Fixed bug in decoder for Explain (Category TargetInfo).
352 Added support for GNU readline in client. Thanks to Jacob Poulsen
353 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
355 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
356 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
357 IMPLEMENTATION! This change was made to the development version before
358 the ZIG decided to retract the amendment. If any users MUST be
359 compatible with the original Update definition, PLEASE CONTACT US, and
360 we will include a separate definition corresponding to the old Update
361 ES. Note that because of the change to the ASN.1 of the
362 TaskPackageRecordStructure we cannot define a single structure that
363 will support both versions.
365 * Added const modifier to buffer parameter for some ODR/BER encoding
366 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
367 completeWAIS, odr_dumpBER.
369 Fixed bug in client.c which caused a crash when a scanResponse didn't
370 contain positionOfTerm.
372 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
373 * will cause an error in a client if a non-YAZ target sends both a
374 * list of Scan entries and non-surrogate diagnostics.
376 Retrieval module enhancements. Tag sets may be typed in the reference
377 to it. From the .abs-file the "tagset" directive takes a third optional
378 integer type for the tag set referenced. From a .tag-file the "include"
379 directive takes a third optional type as well. The old "type" directive
380 in the tag set itself is still recognized but acts as the default type
383 Backend interface change. Individual Scan terms returned from bend_scan
384 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
385 in include/backend.h.
387 Retrieval module enhancements. Multiple tag sets and attribute sets may
388 be specified in abstract syntax specs. Revised the error/warning for
389 logging messages reported by the retrieval module when reading the
392 Object Identifier system (oid_..) changed. The API is backwards
393 compatible but the oid-routines now allocates new OID's when needed.
394 Raw OID's may be specified in oid_getvalbyname.
396 YAZ now uses GNU configure to generate Makefile(s).
398 * Minor changes in some of the member names of DeleteResultSetRequest and
399 DeleteResultSetResponse. See include/proto.h.
401 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
402 and added member 'languages' in TargetInfo (which was missing).
404 Changed the way attribute sets are handled in the retrieval
405 module. These are now cached, just like the abstract syntaxes
408 Changed YAZ so that it links with compiled ASN.1.
410 Added Explain-schema definitions and mapping routines. The following
411 Explain categories have been implemented: AttributeDetails,
412 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
414 Fixed minor bug in Windows version of Server Library.
416 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
418 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
420 Added EXTERNAL: UNIverse Resource Report (non-standard).
422 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
423 ENUMERATED and SET OF.
425 * Added 'const' to some of the char pointer arguments for the
426 functions, data1_read_node, data1_getelementbytagname,
427 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
430 Fixed bug in data1_insert_taggeddata - the last_child member of
431 parent wasn't initialised.
433 * Changed data1_read_record and data1_read_node so that the supplied
434 "SGML"-buffer is read-only. In particular the resulting data1 - tree
435 doesn't refer to any parts of the "SGML"-buffer.
437 Fixed bug in server library (Windows version of statserv_remove).
439 * Changed code so that it compiles as C++. The type definition
440 of Odr_fun which is a member of Odr_arm was changed. The result is,
441 that an explicit typecast is needed for the fun pointer when
442 using Odr_arm - as in:
443 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
445 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
447 Implemented the new structured date and time definition as approved
448 by the ZIG. Added schemaId element to the specificTag in Espec-1
449 (also approved at the last ZIG). Thanks to RVDM.
451 Added some Object identifiers (RVDM).
453 Changed the Update Extended Service (RVDM).
455 Added command "refid" to client which specifies referenceId for
456 the following requests.
458 Implemented extended service handling for server. See ztest.c
459 for an example as well as backend.h. New handlers are registerd
462 * Changed interface for sort in server.
464 Added new members to statserv_options_block. It allows a server
465 to read options from another source than just the command line. Thanks
466 to Charles Woodfield.
468 * Changed definition of Z_Triple in file prt-grs.h - member boolean
469 renamed to zboolean. Some C++ compilers complained about the name.
471 Minor changes to gils.abs. Added index 's' (sort) on title
472 and date/time-last-modified.
476 Fixed bug in server library regarding inetd mode (-i). This bug
477 was introduced by release 1.4.
481 Added sort facility in client and backend server interface.
483 Fixed problem with dependencies in Makefile(s).
485 Fixed bugs for encoders/decoders of extended services and
488 Implemented sub-tree feature for schemas. Sub-trees are
489 referenced in *.abs-files. See explain.abs for an example
490 of the use of this feature.
492 Modified bib1.att; local attributes for ANY didn't include
493 ANY itself (only affects use of the retrieval module).
495 Fixed bug in plain SGML reader in function data1_read_node:
496 tags with prefix "var" was incorrectly interpreted as variants.
498 Added feature "sub-schemas" to enable references to - and definitions
499 of - group of elements.
501 * Removed member parent from type data1_element (in data1.h).
503 Implemented function odr_nullval() that returns the value of
506 * Removed member num_children from data1_node (in data1.h).
508 Made NT service interface part of the server library. The
509 function statserv_main uses the NT service when required and
510 calls the statserv_start / statserv_close routines.
512 Routine zget_SearchRequest and zget_PresentRequest fills
513 resultSetName/Id member with "default" instead of "Default".
515 Fixed memory leak in server. Request queue member wasn't freed.
517 Fixed nmem_exit so that memory is freed.
521 Revised the CCL parser utility to be thread safe.
523 Added function, oid_ent_to_oid, to replace the function
524 oid_getoidbyent, which is not thread safe.
526 * Added nmem_init and nmem_exit to initialize and release
527 NMEM resources. Function nmem_init should be called once in the
528 initial thread before NMEM/ODR is used. statserv.c and client.c
529 have been changed accordingly. The change was necessary to make
530 NMEM thread safe. The NMEM memory pool is shared amongst threads
531 in a process. Unix-based applications will still work fine without
534 Added NT Services interface for the the Z39.50 (statserv) Server.
535 Refer to the ztest.c source on the usage.
537 Windows 95/NT port using MSVC5.0. Project files are included in the
540 * Defined new 'global' handle for the retrieval (data1) system. The
541 new handled, data1_handle, describes the state of the data1 system.
542 This handle is passed as first argument to virtually all
543 data1 related routines. The functions data1_create and data1_destroy
544 creates and destroys a data1 handle respectively.
546 Added ODR encode stream member to all backend request structures
547 init, search, scan etc. This stream should be used to allocate all
548 memory used for the response when thread safe operation is needed.
550 Changed the comstack utility, cs_addstr, to be thread safe. The
551 returned hostname string returned by the function is now part the
554 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
555 function. The cs_straddr takes a COMSTACK handle as argument, so this
556 function must be used after cs_create and before bind/connect.
557 This function is thread safe.
559 Moved test server to 'ztest' directory - generic server code still
560 in 'server' directory.
562 Made prefix query (pquery.c) utility thread safe.
564 Added new function modifier YAZ_EXPORT to 'export' public DLL
565 functions when using windows (see include/yconfig.h).
567 Added definitions to the OID database (util/oid.c) (RVDM).
569 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
571 Added call to ccl_rpn_delete in client program.
573 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
574 release of RPN structure.
576 Added support for C++, headers uses extern "C" for public definitions.
577 With input from RVDM.
579 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
580 Thanks to Ronald van der Meer (RVDM).
582 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
584 Added support for private extensions to the OID database
585 (oid_setprivateoids()). Thanks to RVDM.
587 Added optional, physical ANY (key replication)
589 Fixed null-reference problem in GRS-1 output filter.
591 Proximity operator added to Prefix Query Format (PQF).
593 In test client command "base" accepts multiple databases.
595 Fixed bug in cs_close stack that caused trouble with WINSOCK.
599 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
601 Smallish bug-fixes in the new encoders/decoders (explain).
603 Bug fixed in DeleteRequest.
605 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
607 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
609 Added SOIF syntax (using private OID for now) to retrieval module and client.
611 Added Update extended service.
613 Added SearchResult-1 additional info structure.
615 Added optional CCL (ISO8777) interpreter as separate module. Available
618 --- 1.2 1996/6/10 (1st anniversary release)
620 Added Summary record syntax. Lightly tested.
622 Added OPAC record syntax. Untested.
624 Added ResourceReport service encoders/decoders. Untested.
626 Fixed bug in z_Unit - wrong tagging on unitSystem.
628 Fixed bug in the DiagRecs decoder.
630 Added options for max PDU size and session timeout to frontend-server.
632 Added documentation of query-language parsers and other supporting utilities.
634 [frontend-server] Added Attribute set to the bend_scanrequest API.
636 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
637 surrogate diagnostics were generated.
639 [retrieval] Allow multiple local values for attribute.
641 [retrieval] Allow multiple attributes per element in .abs files. index type.
643 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
647 Minor changes, mostly specific to Zebra's requirements (retrieval)
651 Repaired bug in frontend server when running multiple listening
652 endpoints in dynamic mode.
654 z_External() now won't break if a known, ASN.1 value comes encapsulated
655 in an octet-string. The value will pass through unmodified in an Odr_oct.
657 Added a bit of code to the demo client to decode & display
658 ASN.1-structured records represented in the octet-aligned branch of
659 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
661 Added z_ext_getentbyref() to the ASN module. Doc updated.
663 * Completed the SCAN definition in the ASN module. This may break SCAN
664 code based on older YAZ-versions at compile-time. The fix is easy -
667 * Added 'displayTerm' and OtherInformation to the TermInfo structure
668 under the SCAN definition. Remember to initialize this, server-people.
670 Comstack should now support the WAIS protocol in TCP/IP mode. Note
671 that this does not extend to ODR and ASN.
673 Comstack allows insertion of established socket (primarily for
674 inetd-operation of servers). Doc updated.
676 Front-end server can now start from the inetd in TCP mode. Doc
683 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
684 the rank and record number.
686 Adjustments to the frontend server.
688 Fixed diagnostic BER dumper. It ignored the file argument.
692 Various changes to retrieval module.
694 Changed the union discriminators of the protocol files from enums to
695 ints paired with #defines.
697 *Changed oident.class to oident.oclass to avoid a reserved word in C++
700 *Changed operator in the RPN structure to 'roperator', again to avoid a
703 Fixed problems in Explain decoders/encoders.
707 Memory bug in log module fixed.
711 Occasional malloc() of 0 bytes fixed in d1_espec.c.
713 Bug in Explain DatabaseInfo module fixed.
715 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
719 The shift to v1.0 signals that we now consider the *core* functionality
720 of YAZ reasonably stable (the core being more or less equivalent to
721 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
722 tested (Explain not at all - though that will happen soonish).
724 Minor changes to code to support Windows port.
726 Various minor changes after we're getting to use GRS-1 & co. more.
728 Added Espec-1 format.
730 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
731 of the protocol and it cannot be selected when encoding (maps into 'string'
732 when decoding). Needed to talk to some servers.
734 Demo client can request simple element set names.
736 Added Diagnostic Format encoders/decoders.
738 Added simple Close handling to frontend server (no hooks for resource
739 reporting yet), and demonstration client.
741 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
745 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
746 handled incorrectly when records were requested in the searchResponse. This
747 will only affect you if you use the frontend-server.
749 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
750 Test-client will ask for and print GRS1. Ztest will return dummy records
753 Added Explain encoders/decoders to the service-level API. Untested.
755 Added Extended Services: Item Order encoders and decoders to the Service-
756 level API. Untested. We could use a recent copy of the pertinent bits
757 of the ILL protocol to add those bits.
759 Added diagnostic format 1 encoders/decoders to the service-level API.
762 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
763 odr_cons.c, which causes a more correct output.
765 Fixed handling of searchRequest in frontend server. NextResultSetPosition
766 was always set to 0 when no records were requested in the searchRequest.
768 * Added better external-handling. This shouldn't harm old code that
769 *encodes* externals. It can break code that looks for a
770 'single-ASN1-type' representation, since those types that are known
771 are now decoded immediately. Look at the SUTRS sample code in
772 seshigh.c and client.c. Documentation updated.
774 Handling of structured records in bend_fetchresponse. Length -1 marks
775 structured record, type is deduced from format field.
778 Fairly quick maintenance release to add SUTRS support.
780 Fixed handling of SUTRS records in the demonstration client.
782 * Added format field to the bend_fetchrequest and bend_fetchresponce
783 structures of the backend API (frontend server). When the record is
784 returned, the value of the format field is mapped to an OID. The
785 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
786 of the record. The special value VAL_NONE in the bend_request means
787 that no specific format was requested by the client. Documentation
788 updated accordingly. Test server (ztest) will return a fixed dummy
789 SUTRS record if your client requests SUTRS.
791 Documentation updated accordingly.
793 You can now set external libraries and RANLIB support in the top-level
797 First public release.
