1 Possible compatibility problems with earlier versions marked with '*'.
7 PQF parser rejects bad queries - including those with extra
8 characters in them. PQF parser used to silently ignore that.
9 Cleaner API for PQF added, which allows you to get detailed
10 error information for bad queries (see yaz/pquery.h).
12 Fixed bug in ZOOM_record_get for type "database".
14 Implemented mini iconv library supporting conversions between
15 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
17 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
21 Fixed ZOOM C record cache so that preferredRecordSyntax and
22 elementSetName is used to check for already fetched records.
26 Added three members in bend_initrequest structure to facilitate
27 character set negotiation.
29 Fixed a bug in frontend server that could cause indefinite
30 loops under rare conditions.
32 Revised character set utilities (charneg.h) so that encoding
33 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
35 For PQF, directive @term <type> sets term type for Scan/Search.
36 Here <type> is general, string, numeric, null. The term type
37 is inherited - just like @attr.
39 New call odr_set_charset that sets character set conversion for
40 international-strings on a ODR stream. Prototype is:
41 int odr_set_charset(ODR o, const char *to, const char *from);
42 The InternationalString is still represented as C string in YAZ
43 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
44 won't). On the protocol level, you can use any encoding.
46 Support for UNIX sockets in ZOOM.
48 Solaris recv sometimes returns errno == ENOENT. It is treated as
49 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
51 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
52 both client and server. Code by Morten Bøgeskov.
56 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
57 that they can be used directly from Visual Basic. You must recompile
58 your windows APP if you're using ZOOM.
60 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
61 Commands "lang" and "charset" sets language and character set respectively.
62 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
63 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
65 Attributes from multiple CCL fields may be OR'ed rather than merged
66 using directive "@field or". Fields are still merged by default -
67 equivalent to "@field merge".
69 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
72 Fixed bug in zget for parameter ExtendedServicesResponse.
78 Added PQF feature: '@attr type=value' may be written as '@type=value'.
80 Client displays USR.1:SearchResult-1 (hits per term).
82 Additional Search Info for search in Generic Frontend Server.
84 Fixed CCL parsing of "field=s".
86 WIN32 installer - using the excellent NSIS software from nullsoft.
88 Fixed CCL parsing of "field = - <number>".
90 Added function yaz_marc_decode that decodes MARC for line mode
91 display or XML (similar to that used by JZKit).
93 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
94 Z39.50. But ISO/ILL was, however.
96 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
97 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

100 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
104 New YAZ client features: Command completion and new commands:
105 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
106 Code provided by Jacob Poulsen.
108 New call oid_trav, that visits all registered OIDs via callback.
110 Function ZOOM_record_get now returns const char pointer rather than
111 void pointer. It saves a lot of type casts.
113 For YAZ client, command "auth" now allows you to set authentication
114 in IdPass style. It is enabled when three tokens are given - order
115 is user, group and password.
117 Fix memory leaks in MARC record handling for ZOOM.
119 New option for YAZ client, -k <kilobytes> that sets
120 maximum record size. Similar to -k option for generic frontend
121 server and yaz-ztest.
123 More fixes for scan. Non-zero stepSize handled. OID's fixes.
125 Prefix query parser reports "fail" when bad attribute set is given.
127 Fix in MARC decoder. Proximity logging. Fix for attribute set
128 in scan handler for server. Patches by Shigeru Ishida.
130 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
133 Configure option --with-openssl=<dir> now works when a directory is
134 specified. Patch provided by Morten Bøgeskov.
136 New option for YAZ client, -u <auth>, that sets authentication.
138 ZOOM fix: error information was sometimes "missing", since error
139 was cleared/reset too when it shouldn't.
141 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
145 Scan for ZOOM API. New object ZOOM_scanset. New functions
146 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
147 ZOOM_scanset_destroy.
149 New ZOOM function, ZOOM_connection_last_event, that returns type
150 of last event (such as "receive data", "send data", "apdu received",
153 New ZOOM option, schema, that specifies shema OID for retrieval.
155 New CCL feature. Qualifiers can be aliases for one or more
156 other qualifiers (if more than one is given, OR is used).
158 ZOOM uses named result sets if target supports it.
160 Two new YAZ client commands: . (dot, which sources a script of YAZ
161 client commands), and ! (to execute shell command.). Implemented
164 Working on Debian packages.
168 YAZ client enables named result sets only if target supports it.
170 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
172 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
173 with key="host" to get same result.
175 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
176 Function Z3950_resultset_record(s) returns references to records
177 "owned" by resultset. To become owner use Z3950_record_clone.
179 Function z_ext_record handles Extended Services. Thanks to
184 CCL Parser fix: ignore token comma when dealing with and-lists.
186 Documentation updates for COMSTACK.
188 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
189 Changed prototype Z3950_records. For some functions, int parameters
190 were changed to size_t.
192 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
195 New MARC decode/display function, marc_display_exl, which properly rejects
196 non-ISO2709 records. YAZ client uses it.
200 Fix bug: local attribute set wasn't set correctly in PQF strings.
204 * Old Z39.50 codecs no longer supported.
206 Added ZOOM C binding. See http://zoom.z3950.org/
208 Renamed states for COMSTACKs to avoid confusion with events.
210 Implemented cs_look and proper cs_rcvconnect.
212 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
214 Configure detects POSIX threads on OpenBSD.
216 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
217 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
219 When error is returned from present handler, non-surrogate diagnostic
220 is returned in present response (and fetch handler is no longer called).
222 * Minor adjustments to pquery parser (PQF). Token characters may be
223 escaped by using backslash (C-style).
225 PQF parser allows string attribute values to be specified. For @attr,
226 non-numeric characters after the equal-sign are treated as strings
227 (e.g. @attr 9=title).
229 CCL trunction character may be defined (@truncation in file)
231 * function zget_ExtendedServicesRequest sets waitAction to
232 waitIfPossible (was wait).
234 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
237 CCL operator names may be set in field definition files (CCL_bibset).
238 See ccl/bib1 for an example.
240 Fixes in ASN.1 compiler for C++ compatibility.
242 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
243 and "op_or" to avoid conflict with C++.
245 Fixed problem with GNU readline detection on Redhat 7.0.
247 Added step-size for Scan backend handler.
249 Fixed bug that made the frontend server crash when no attribute
250 set was specified for scan.
252 Front-end server automatically switches to original working directory
253 when installed as an NT service. Previously -w had to be specified to
256 Added extended attributes for retrieval module (data1), so that data1
257 records carry d1_readXML/SGML attributes. d1_read also supports
258 null-data rules ( <tag/>)
260 On UNIX when POSIX threads are available, a separate library libyazthread
261 is created. Programmers should link with that library and the yaz library
262 when using threads. The reason for the split was that some applications
263 on Linux, such as Apache, doesn't work well when using shared objects that
266 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
267 (or any frontend server) in SSL mode by specifying ssl: followed by
268 address. Only tested on UNIX.
270 Added feature for CCL module. Virtual structure s=al or s=ol generates
271 and-list and or-list respectively instead of phrase search.
275 * Added prefix "yaz_" for the functions log_init.., log_file.. and
276 log_mask_str. This was done to avoid name conflicts with other libraries
277 (such as other PHP extensions).
279 Added raw OID member for preferred record syntax (request_format_raw)
280 and returned record syntax (output_format_raw) for backend fetch method.
282 Config file yaz-config now accepts options so that it returns specific
283 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
285 Shared library support for UNIX using GNU libtool.
287 * Modified backend interface. Request/Response struct's replaced by
288 one read/write C struct. For example bend_fetchrequest and
289 bend_fetchresult have been replaced by single bend_fetch_rr struct.
290 Every handler - even search has to be registered in bend_init
291 handler. This means that the YAZ library no longer refers to
292 external functions and it makes it possible to make the whole
293 thing a single DLL/SO.
295 Added Segment handler for backend server.
297 Added Zmbol/Zebra administrative functions to YAZ client.
299 Threaded frontend server on UNIX (when POSIX Threads are available).
300 Starting the server with option -T enables multi-threading.
304 Added configure option --enable-comp/disable-comp to control use
305 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
306 located in sub directory asn.
308 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
309 in ${exec_prefix}/bin along with the other programs yaz-client and
312 GNU automake used to maintain makefiles.
316 Changed retrieval module so that we can load records with no abstract
317 syntax defined. Tagpaths in these records are fully composed of string
320 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
324 On UNIX, the generated makefile now supports a proper 'make install'.
325 The prefix can be set via GNU configure to set the install location
326 (default is /usr/local).
328 * YAZ programs client and ztest were renamed to yaz-client and
329 yaz-ztest to avoid conflicts when users install YAZ in "standard"
330 locations, such as /usr/bin,/usr/local/bin,etc.
332 * YAZ Header files were moved from include to include/yaz. YAZ Header
333 files are referred to as include <yaz/log.h> rather than <log.h>.
334 The YAZ include path (-I ..) is therefore the same as before. Programmers
335 should update their #include statements or use -Ipath/include/yaz
336 instead. The main motivation for doing this change is that YAZ header files
337 can be installed in "standard" locations /usr/include,/usr/local/include
338 without introducing conflicts, since ALL YAZ header files are stored
339 in subdirectory yaz (under /usr/include for example).
341 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
342 rather than project/workspace files. We switched because project files
343 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
346 Changed name of logging function, logf, to yaz_log, to prevent name
347 clash with some math-log functions. The YAZ header log.h defines logf
348 to yaz_log (#define) so there should be no incompatibilities by this
351 Added bend_start/bend_stop handlers for server. These handler are
352 called on start/stop of server. For windows they are called whenever
353 a service is started/stopped.
355 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
356 a fairly small ASN.1 compiler written in Tcl. The compiler is located
357 in util/yc.tcl. The auto-generated C code structures are, in a few
358 cases, incompatible with the old decoders. There are differences in the
359 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
360 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
361 The preprocessor variable ASN_COMPILED is defined when the compiled
362 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
363 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
364 wish to use the old encoders/decoders you can specify --disable-yc
367 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
368 version so that it supports both new - and old version of DB Update
370 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
371 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
372 change. The name parameter can be set to 0 in which no name is specified
373 for the construction. The macros odr_implicit and odr_explicit sets name
374 parameter to zero for the construction involved. New macros
375 odr_implicit_tag and odr_explicit_tag are similar to the others,
376 except that a name parameter is added. For programmers' that don't use
377 ODR they probably only need to change the call to z_APDU and z_External.
379 Added access control facility by interfacing the TCP wrapper library.
380 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
381 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
382 name of the daemon and enables the access control as specified in
383 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
385 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
386 den Dool <H.M.vdnDool@kub.nl>.
388 Added reference ID parameter to most functions in server API - refer
389 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
391 Changed name of ccl library to libccl.a (was ccl.a).
393 Fixed bug in decoder for Explain (Category TargetInfo).
395 Added support for GNU readline in client. Thanks to Jacob Poulsen
396 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
398 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
399 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
400 IMPLEMENTATION! This change was made to the development version before
401 the ZIG decided to retract the amendment. If any users MUST be
402 compatible with the original Update definition, PLEASE CONTACT US, and
403 we will include a separate definition corresponding to the old Update
404 ES. Note that because of the change to the ASN.1 of the
405 TaskPackageRecordStructure we cannot define a single structure that
406 will support both versions.
408 * Added const modifier to buffer parameter for some ODR/BER encoding
409 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
410 completeWAIS, odr_dumpBER.
412 Fixed bug in client.c which caused a crash when a scanResponse didn't
413 contain positionOfTerm.
415 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
416 * will cause an error in a client if a non-YAZ target sends both a
417 * list of Scan entries and non-surrogate diagnostics.
419 Retrieval module enhancements. Tag sets may be typed in the reference
420 to it. From the .abs-file the "tagset" directive takes a third optional
421 integer type for the tag set referenced. From a .tag-file the "include"
422 directive takes a third optional type as well. The old "type" directive
423 in the tag set itself is still recognized but acts as the default type
426 Backend interface change. Individual Scan terms returned from bend_scan
427 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
428 in include/backend.h.
430 Retrieval module enhancements. Multiple tag sets and attribute sets may
431 be specified in abstract syntax specs. Revised the error/warning for
432 logging messages reported by the retrieval module when reading the
435 Object Identifier system (oid_..) changed. The API is backwards
436 compatible but the oid-routines now allocates new OID's when needed.
437 Raw OID's may be specified in oid_getvalbyname.
439 YAZ now uses GNU configure to generate Makefile(s).
441 * Minor changes in some of the member names of DeleteResultSetRequest and
442 DeleteResultSetResponse. See include/proto.h.
444 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
445 and added member 'languages' in TargetInfo (which was missing).
447 Changed the way attribute sets are handled in the retrieval
448 module. These are now cached, just like the abstract syntaxes
451 Changed YAZ so that it links with compiled ASN.1.
453 Added Explain-schema definitions and mapping routines. The following
454 Explain categories have been implemented: AttributeDetails,
455 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
457 Fixed minor bug in Windows version of Server Library.
459 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
461 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
463 Added EXTERNAL: UNIverse Resource Report (non-standard).
465 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
466 ENUMERATED and SET OF.
468 * Added 'const' to some of the char pointer arguments for the
469 functions, data1_read_node, data1_getelementbytagname,
470 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
473 Fixed bug in data1_insert_taggeddata - the last_child member of
474 parent wasn't initialised.
476 * Changed data1_read_record and data1_read_node so that the supplied
477 "SGML"-buffer is read-only. In particular the resulting data1 - tree
478 doesn't refer to any parts of the "SGML"-buffer.
480 Fixed bug in server library (Windows version of statserv_remove).
482 * Changed code so that it compiles as C++. The type definition
483 of Odr_fun which is a member of Odr_arm was changed. The result is,
484 that an explicit typecast is needed for the fun pointer when
485 using Odr_arm - as in:
486 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
488 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
490 Implemented the new structured date and time definition as approved
491 by the ZIG. Added schemaId element to the specificTag in Espec-1
492 (also approved at the last ZIG). Thanks to RVDM.
494 Added some Object identifiers (RVDM).
496 Changed the Update Extended Service (RVDM).
498 Added command "refid" to client which specifies referenceId for
499 the following requests.
501 Implemented extended service handling for server. See ztest.c
502 for an example as well as backend.h. New handlers are registerd
505 * Changed interface for sort in server.
507 Added new members to statserv_options_block. It allows a server
508 to read options from another source than just the command line. Thanks
509 to Charles Woodfield.
511 * Changed definition of Z_Triple in file prt-grs.h - member boolean
512 renamed to zboolean. Some C++ compilers complained about the name.
514 Minor changes to gils.abs. Added index 's' (sort) on title
515 and date/time-last-modified.
519 Fixed bug in server library regarding inetd mode (-i). This bug
520 was introduced by release 1.4.
524 Added sort facility in client and backend server interface.
526 Fixed problem with dependencies in Makefile(s).
528 Fixed bugs for encoders/decoders of extended services and
531 Implemented sub-tree feature for schemas. Sub-trees are
532 referenced in *.abs-files. See explain.abs for an example
533 of the use of this feature.
535 Modified bib1.att; local attributes for ANY didn't include
536 ANY itself (only affects use of the retrieval module).
538 Fixed bug in plain SGML reader in function data1_read_node:
539 tags with prefix "var" was incorrectly interpreted as variants.
541 Added feature "sub-schemas" to enable references to - and definitions
542 of - group of elements.
544 * Removed member parent from type data1_element (in data1.h).
546 Implemented function odr_nullval() that returns the value of
549 * Removed member num_children from data1_node (in data1.h).
551 Made NT service interface part of the server library. The
552 function statserv_main uses the NT service when required and
553 calls the statserv_start / statserv_close routines.
555 Routine zget_SearchRequest and zget_PresentRequest fills
556 resultSetName/Id member with "default" instead of "Default".
558 Fixed memory leak in server. Request queue member wasn't freed.
560 Fixed nmem_exit so that memory is freed.
564 Revised the CCL parser utility to be thread safe.
566 Added function, oid_ent_to_oid, to replace the function
567 oid_getoidbyent, which is not thread safe.
569 * Added nmem_init and nmem_exit to initialize and release
570 NMEM resources. Function nmem_init should be called once in the
571 initial thread before NMEM/ODR is used. statserv.c and client.c
572 have been changed accordingly. The change was necessary to make
573 NMEM thread safe. The NMEM memory pool is shared amongst threads
574 in a process. Unix-based applications will still work fine without
577 Added NT Services interface for the the Z39.50 (statserv) Server.
578 Refer to the ztest.c source on the usage.
580 Windows 95/NT port using MSVC5.0. Project files are included in the
583 * Defined new 'global' handle for the retrieval (data1) system. The
584 new handled, data1_handle, describes the state of the data1 system.
585 This handle is passed as first argument to virtually all
586 data1 related routines. The functions data1_create and data1_destroy
587 creates and destroys a data1 handle respectively.
589 Added ODR encode stream member to all backend request structures
590 init, search, scan etc. This stream should be used to allocate all
591 memory used for the response when thread safe operation is needed.
593 Changed the comstack utility, cs_addstr, to be thread safe. The
594 returned hostname string returned by the function is now part the
597 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
598 function. The cs_straddr takes a COMSTACK handle as argument, so this
599 function must be used after cs_create and before bind/connect.
600 This function is thread safe.
602 Moved test server to 'ztest' directory - generic server code still
603 in 'server' directory.
605 Made prefix query (pquery.c) utility thread safe.
607 Added new function modifier YAZ_EXPORT to 'export' public DLL
608 functions when using windows (see include/yconfig.h).
610 Added definitions to the OID database (util/oid.c) (RVDM).
612 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
614 Added call to ccl_rpn_delete in client program.
616 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
617 release of RPN structure.
619 Added support for C++, headers uses extern "C" for public definitions.
620 With input from RVDM.
622 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
623 Thanks to Ronald van der Meer (RVDM).
625 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
627 Added support for private extensions to the OID database
628 (oid_setprivateoids()). Thanks to RVDM.
630 Added optional, physical ANY (key replication)
632 Fixed null-reference problem in GRS-1 output filter.
634 Proximity operator added to Prefix Query Format (PQF).
636 In test client command "base" accepts multiple databases.
638 Fixed bug in cs_close stack that caused trouble with WINSOCK.
642 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
644 Smallish bug-fixes in the new encoders/decoders (explain).
646 Bug fixed in DeleteRequest.
648 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
650 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
652 Added SOIF syntax (using private OID for now) to retrieval module and client.
654 Added Update extended service.
656 Added SearchResult-1 additional info structure.
658 Added optional CCL (ISO8777) interpreter as separate module. Available
661 --- 1.2 1996/6/10 (1st anniversary release)
663 Added Summary record syntax. Lightly tested.
665 Added OPAC record syntax. Untested.
667 Added ResourceReport service encoders/decoders. Untested.
669 Fixed bug in z_Unit - wrong tagging on unitSystem.
671 Fixed bug in the DiagRecs decoder.
673 Added options for max PDU size and session timeout to frontend-server.
675 Added documentation of query-language parsers and other supporting utilities.
677 [frontend-server] Added Attribute set to the bend_scanrequest API.
679 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
680 surrogate diagnostics were generated.
682 [retrieval] Allow multiple local values for attribute.
684 [retrieval] Allow multiple attributes per element in .abs files. index type.
686 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
690 Minor changes, mostly specific to Zebra's requirements (retrieval)
694 Repaired bug in frontend server when running multiple listening
695 endpoints in dynamic mode.
697 z_External() now won't break if a known, ASN.1 value comes encapsulated
698 in an octet-string. The value will pass through unmodified in an Odr_oct.
700 Added a bit of code to the demo client to decode & display
701 ASN.1-structured records represented in the octet-aligned branch of
702 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
704 Added z_ext_getentbyref() to the ASN module. Doc updated.
706 * Completed the SCAN definition in the ASN module. This may break SCAN
707 code based on older YAZ-versions at compile-time. The fix is easy -
710 * Added 'displayTerm' and OtherInformation to the TermInfo structure
711 under the SCAN definition. Remember to initialize this, server-people.
713 Comstack should now support the WAIS protocol in TCP/IP mode. Note
714 that this does not extend to ODR and ASN.
716 Comstack allows insertion of established socket (primarily for
717 inetd-operation of servers). Doc updated.
719 Front-end server can now start from the inetd in TCP mode. Doc
726 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
727 the rank and record number.
729 Adjustments to the frontend server.
731 Fixed diagnostic BER dumper. It ignored the file argument.
735 Various changes to retrieval module.
737 Changed the union discriminators of the protocol files from enums to
738 ints paired with #defines.
740 *Changed oident.class to oident.oclass to avoid a reserved word in C++
743 *Changed operator in the RPN structure to 'roperator', again to avoid a
746 Fixed problems in Explain decoders/encoders.
750 Memory bug in log module fixed.
754 Occasional malloc() of 0 bytes fixed in d1_espec.c.
756 Bug in Explain DatabaseInfo module fixed.
758 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
762 The shift to v1.0 signals that we now consider the *core* functionality
763 of YAZ reasonably stable (the core being more or less equivalent to
764 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
765 tested (Explain not at all - though that will happen soonish).
767 Minor changes to code to support Windows port.
769 Various minor changes after we're getting to use GRS-1 & co. more.
771 Added Espec-1 format.
773 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
774 of the protocol and it cannot be selected when encoding (maps into 'string'
775 when decoding). Needed to talk to some servers.
777 Demo client can request simple element set names.
779 Added Diagnostic Format encoders/decoders.
781 Added simple Close handling to frontend server (no hooks for resource
782 reporting yet), and demonstration client.
784 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
788 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
789 handled incorrectly when records were requested in the searchResponse. This
790 will only affect you if you use the frontend-server.
792 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
793 Test-client will ask for and print GRS1. Ztest will return dummy records
796 Added Explain encoders/decoders to the service-level API. Untested.
798 Added Extended Services: Item Order encoders and decoders to the Service-
799 level API. Untested. We could use a recent copy of the pertinent bits
800 of the ILL protocol to add those bits.
802 Added diagnostic format 1 encoders/decoders to the service-level API.
805 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
806 odr_cons.c, which causes a more correct output.
808 Fixed handling of searchRequest in frontend server. NextResultSetPosition
809 was always set to 0 when no records were requested in the searchRequest.
811 * Added better external-handling. This shouldn't harm old code that
812 *encodes* externals. It can break code that looks for a
813 'single-ASN1-type' representation, since those types that are known
814 are now decoded immediately. Look at the SUTRS sample code in
815 seshigh.c and client.c. Documentation updated.
817 Handling of structured records in bend_fetchresponse. Length -1 marks
818 structured record, type is deduced from format field.
821 Fairly quick maintenance release to add SUTRS support.
823 Fixed handling of SUTRS records in the demonstration client.
825 * Added format field to the bend_fetchrequest and bend_fetchresponce
826 structures of the backend API (frontend server). When the record is
827 returned, the value of the format field is mapped to an OID. The
828 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
829 of the record. The special value VAL_NONE in the bend_request means
830 that no specific format was requested by the client. Documentation
831 updated accordingly. Test server (ztest) will return a fixed dummy
832 SUTRS record if your client requests SUTRS.
834 Documentation updated accordingly.
836 You can now set external libraries and RANLIB support in the top-level
840 First public release.
