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

103 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
107 New YAZ client features: Command completion and new commands:
108 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
109 Code provided by Jacob Poulsen.
111 New call oid_trav, that visits all registered OIDs via callback.
113 Function ZOOM_record_get now returns const char pointer rather than
114 void pointer. It saves a lot of type casts.
116 For YAZ client, command "auth" now allows you to set authentication
117 in IdPass style. It is enabled when three tokens are given - order
118 is user, group and password.
120 Fix memory leaks in MARC record handling for ZOOM.
122 New option for YAZ client, -k <kilobytes> that sets
123 maximum record size. Similar to -k option for generic frontend
124 server and yaz-ztest.
126 More fixes for scan. Non-zero stepSize handled. OID's fixes.
128 Prefix query parser reports "fail" when bad attribute set is given.
130 Fix in MARC decoder. Proximity logging. Fix for attribute set
131 in scan handler for server. Patches by Shigeru Ishida.
133 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
136 Configure option --with-openssl=<dir> now works when a directory is
137 specified. Patch provided by Morten Bøgeskov.
139 New option for YAZ client, -u <auth>, that sets authentication.
141 ZOOM fix: error information was sometimes "missing", since error
142 was cleared/reset too when it shouldn't.
144 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
148 Scan for ZOOM API. New object ZOOM_scanset. New functions
149 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
150 ZOOM_scanset_destroy.
152 New ZOOM function, ZOOM_connection_last_event, that returns type
153 of last event (such as "receive data", "send data", "apdu received",
156 New ZOOM option, schema, that specifies shema OID for retrieval.
158 New CCL feature. Qualifiers can be aliases for one or more
159 other qualifiers (if more than one is given, OR is used).
161 ZOOM uses named result sets if target supports it.
163 Two new YAZ client commands: . (dot, which sources a script of YAZ
164 client commands), and ! (to execute shell command.). Implemented
167 Working on Debian packages.
171 YAZ client enables named result sets only if target supports it.
173 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
175 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
176 with key="host" to get same result.
178 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
179 Function Z3950_resultset_record(s) returns references to records
180 "owned" by resultset. To become owner use Z3950_record_clone.
182 Function z_ext_record handles Extended Services. Thanks to
187 CCL Parser fix: ignore token comma when dealing with and-lists.
189 Documentation updates for COMSTACK.
191 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
192 Changed prototype Z3950_records. For some functions, int parameters
193 were changed to size_t.
195 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
198 New MARC decode/display function, marc_display_exl, which properly rejects
199 non-ISO2709 records. YAZ client uses it.
203 Fix bug: local attribute set wasn't set correctly in PQF strings.
207 * Old Z39.50 codecs no longer supported.
209 Added ZOOM C binding. See http://zoom.z3950.org/
211 Renamed states for COMSTACKs to avoid confusion with events.
213 Implemented cs_look and proper cs_rcvconnect.
215 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
217 Configure detects POSIX threads on OpenBSD.
219 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
220 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
222 When error is returned from present handler, non-surrogate diagnostic
223 is returned in present response (and fetch handler is no longer called).
225 * Minor adjustments to pquery parser (PQF). Token characters may be
226 escaped by using backslash (C-style).
228 PQF parser allows string attribute values to be specified. For @attr,
229 non-numeric characters after the equal-sign are treated as strings
230 (e.g. @attr 9=title).
232 CCL trunction character may be defined (@truncation in file)
234 * function zget_ExtendedServicesRequest sets waitAction to
235 waitIfPossible (was wait).
237 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
240 CCL operator names may be set in field definition files (CCL_bibset).
241 See ccl/bib1 for an example.
243 Fixes in ASN.1 compiler for C++ compatibility.
245 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
246 and "op_or" to avoid conflict with C++.
248 Fixed problem with GNU readline detection on Redhat 7.0.
250 Added step-size for Scan backend handler.
252 Fixed bug that made the frontend server crash when no attribute
253 set was specified for scan.
255 Front-end server automatically switches to original working directory
256 when installed as an NT service. Previously -w had to be specified to
259 Added extended attributes for retrieval module (data1), so that data1
260 records carry d1_readXML/SGML attributes. d1_read also supports
261 null-data rules ( <tag/>)
263 On UNIX when POSIX threads are available, a separate library libyazthread
264 is created. Programmers should link with that library and the yaz library
265 when using threads. The reason for the split was that some applications
266 on Linux, such as Apache, doesn't work well when using shared objects that
269 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
270 (or any frontend server) in SSL mode by specifying ssl: followed by
271 address. Only tested on UNIX.
273 Added feature for CCL module. Virtual structure s=al or s=ol generates
274 and-list and or-list respectively instead of phrase search.
278 * Added prefix "yaz_" for the functions log_init.., log_file.. and
279 log_mask_str. This was done to avoid name conflicts with other libraries
280 (such as other PHP extensions).
282 Added raw OID member for preferred record syntax (request_format_raw)
283 and returned record syntax (output_format_raw) for backend fetch method.
285 Config file yaz-config now accepts options so that it returns specific
286 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
288 Shared library support for UNIX using GNU libtool.
290 * Modified backend interface. Request/Response struct's replaced by
291 one read/write C struct. For example bend_fetchrequest and
292 bend_fetchresult have been replaced by single bend_fetch_rr struct.
293 Every handler - even search has to be registered in bend_init
294 handler. This means that the YAZ library no longer refers to
295 external functions and it makes it possible to make the whole
296 thing a single DLL/SO.
298 Added Segment handler for backend server.
300 Added Zmbol/Zebra administrative functions to YAZ client.
302 Threaded frontend server on UNIX (when POSIX Threads are available).
303 Starting the server with option -T enables multi-threading.
307 Added configure option --enable-comp/disable-comp to control use
308 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
309 located in sub directory asn.
311 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
312 in ${exec_prefix}/bin along with the other programs yaz-client and
315 GNU automake used to maintain makefiles.
319 Changed retrieval module so that we can load records with no abstract
320 syntax defined. Tagpaths in these records are fully composed of string
323 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
327 On UNIX, the generated makefile now supports a proper 'make install'.
328 The prefix can be set via GNU configure to set the install location
329 (default is /usr/local).
331 * YAZ programs client and ztest were renamed to yaz-client and
332 yaz-ztest to avoid conflicts when users install YAZ in "standard"
333 locations, such as /usr/bin,/usr/local/bin,etc.
335 * YAZ Header files were moved from include to include/yaz. YAZ Header
336 files are referred to as include <yaz/log.h> rather than <log.h>.
337 The YAZ include path (-I ..) is therefore the same as before. Programmers
338 should update their #include statements or use -Ipath/include/yaz
339 instead. The main motivation for doing this change is that YAZ header files
340 can be installed in "standard" locations /usr/include,/usr/local/include
341 without introducing conflicts, since ALL YAZ header files are stored
342 in subdirectory yaz (under /usr/include for example).
344 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
345 rather than project/workspace files. We switched because project files
346 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
349 Changed name of logging function, logf, to yaz_log, to prevent name
350 clash with some math-log functions. The YAZ header log.h defines logf
351 to yaz_log (#define) so there should be no incompatibilities by this
354 Added bend_start/bend_stop handlers for server. These handler are
355 called on start/stop of server. For windows they are called whenever
356 a service is started/stopped.
358 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
359 a fairly small ASN.1 compiler written in Tcl. The compiler is located
360 in util/yc.tcl. The auto-generated C code structures are, in a few
361 cases, incompatible with the old decoders. There are differences in the
362 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
363 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
364 The preprocessor variable ASN_COMPILED is defined when the compiled
365 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
366 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
367 wish to use the old encoders/decoders you can specify --disable-yc
370 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
371 version so that it supports both new - and old version of DB Update
373 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
374 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
375 change. The name parameter can be set to 0 in which no name is specified
376 for the construction. The macros odr_implicit and odr_explicit sets name
377 parameter to zero for the construction involved. New macros
378 odr_implicit_tag and odr_explicit_tag are similar to the others,
379 except that a name parameter is added. For programmers' that don't use
380 ODR they probably only need to change the call to z_APDU and z_External.
382 Added access control facility by interfacing the TCP wrapper library.
383 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
384 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
385 name of the daemon and enables the access control as specified in
386 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
388 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
389 den Dool <H.M.vdnDool@kub.nl>.
391 Added reference ID parameter to most functions in server API - refer
392 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
394 Changed name of ccl library to libccl.a (was ccl.a).
396 Fixed bug in decoder for Explain (Category TargetInfo).
398 Added support for GNU readline in client. Thanks to Jacob Poulsen
399 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
401 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
402 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
403 IMPLEMENTATION! This change was made to the development version before
404 the ZIG decided to retract the amendment. If any users MUST be
405 compatible with the original Update definition, PLEASE CONTACT US, and
406 we will include a separate definition corresponding to the old Update
407 ES. Note that because of the change to the ASN.1 of the
408 TaskPackageRecordStructure we cannot define a single structure that
409 will support both versions.
411 * Added const modifier to buffer parameter for some ODR/BER encoding
412 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
413 completeWAIS, odr_dumpBER.
415 Fixed bug in client.c which caused a crash when a scanResponse didn't
416 contain positionOfTerm.
418 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
419 * will cause an error in a client if a non-YAZ target sends both a
420 * list of Scan entries and non-surrogate diagnostics.
422 Retrieval module enhancements. Tag sets may be typed in the reference
423 to it. From the .abs-file the "tagset" directive takes a third optional
424 integer type for the tag set referenced. From a .tag-file the "include"
425 directive takes a third optional type as well. The old "type" directive
426 in the tag set itself is still recognized but acts as the default type
429 Backend interface change. Individual Scan terms returned from bend_scan
430 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
431 in include/backend.h.
433 Retrieval module enhancements. Multiple tag sets and attribute sets may
434 be specified in abstract syntax specs. Revised the error/warning for
435 logging messages reported by the retrieval module when reading the
438 Object Identifier system (oid_..) changed. The API is backwards
439 compatible but the oid-routines now allocates new OID's when needed.
440 Raw OID's may be specified in oid_getvalbyname.
442 YAZ now uses GNU configure to generate Makefile(s).
444 * Minor changes in some of the member names of DeleteResultSetRequest and
445 DeleteResultSetResponse. See include/proto.h.
447 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
448 and added member 'languages' in TargetInfo (which was missing).
450 Changed the way attribute sets are handled in the retrieval
451 module. These are now cached, just like the abstract syntaxes
454 Changed YAZ so that it links with compiled ASN.1.
456 Added Explain-schema definitions and mapping routines. The following
457 Explain categories have been implemented: AttributeDetails,
458 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
460 Fixed minor bug in Windows version of Server Library.
462 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
464 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
466 Added EXTERNAL: UNIverse Resource Report (non-standard).
468 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
469 ENUMERATED and SET OF.
471 * Added 'const' to some of the char pointer arguments for the
472 functions, data1_read_node, data1_getelementbytagname,
473 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
476 Fixed bug in data1_insert_taggeddata - the last_child member of
477 parent wasn't initialised.
479 * Changed data1_read_record and data1_read_node so that the supplied
480 "SGML"-buffer is read-only. In particular the resulting data1 - tree
481 doesn't refer to any parts of the "SGML"-buffer.
483 Fixed bug in server library (Windows version of statserv_remove).
485 * Changed code so that it compiles as C++. The type definition
486 of Odr_fun which is a member of Odr_arm was changed. The result is,
487 that an explicit typecast is needed for the fun pointer when
488 using Odr_arm - as in:
489 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
491 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
493 Implemented the new structured date and time definition as approved
494 by the ZIG. Added schemaId element to the specificTag in Espec-1
495 (also approved at the last ZIG). Thanks to RVDM.
497 Added some Object identifiers (RVDM).
499 Changed the Update Extended Service (RVDM).
501 Added command "refid" to client which specifies referenceId for
502 the following requests.
504 Implemented extended service handling for server. See ztest.c
505 for an example as well as backend.h. New handlers are registerd
508 * Changed interface for sort in server.
510 Added new members to statserv_options_block. It allows a server
511 to read options from another source than just the command line. Thanks
512 to Charles Woodfield.
514 * Changed definition of Z_Triple in file prt-grs.h - member boolean
515 renamed to zboolean. Some C++ compilers complained about the name.
517 Minor changes to gils.abs. Added index 's' (sort) on title
518 and date/time-last-modified.
522 Fixed bug in server library regarding inetd mode (-i). This bug
523 was introduced by release 1.4.
527 Added sort facility in client and backend server interface.
529 Fixed problem with dependencies in Makefile(s).
531 Fixed bugs for encoders/decoders of extended services and
534 Implemented sub-tree feature for schemas. Sub-trees are
535 referenced in *.abs-files. See explain.abs for an example
536 of the use of this feature.
538 Modified bib1.att; local attributes for ANY didn't include
539 ANY itself (only affects use of the retrieval module).
541 Fixed bug in plain SGML reader in function data1_read_node:
542 tags with prefix "var" was incorrectly interpreted as variants.
544 Added feature "sub-schemas" to enable references to - and definitions
545 of - group of elements.
547 * Removed member parent from type data1_element (in data1.h).
549 Implemented function odr_nullval() that returns the value of
552 * Removed member num_children from data1_node (in data1.h).
554 Made NT service interface part of the server library. The
555 function statserv_main uses the NT service when required and
556 calls the statserv_start / statserv_close routines.
558 Routine zget_SearchRequest and zget_PresentRequest fills
559 resultSetName/Id member with "default" instead of "Default".
561 Fixed memory leak in server. Request queue member wasn't freed.
563 Fixed nmem_exit so that memory is freed.
567 Revised the CCL parser utility to be thread safe.
569 Added function, oid_ent_to_oid, to replace the function
570 oid_getoidbyent, which is not thread safe.
572 * Added nmem_init and nmem_exit to initialize and release
573 NMEM resources. Function nmem_init should be called once in the
574 initial thread before NMEM/ODR is used. statserv.c and client.c
575 have been changed accordingly. The change was necessary to make
576 NMEM thread safe. The NMEM memory pool is shared amongst threads
577 in a process. Unix-based applications will still work fine without
580 Added NT Services interface for the the Z39.50 (statserv) Server.
581 Refer to the ztest.c source on the usage.
583 Windows 95/NT port using MSVC5.0. Project files are included in the
586 * Defined new 'global' handle for the retrieval (data1) system. The
587 new handled, data1_handle, describes the state of the data1 system.
588 This handle is passed as first argument to virtually all
589 data1 related routines. The functions data1_create and data1_destroy
590 creates and destroys a data1 handle respectively.
592 Added ODR encode stream member to all backend request structures
593 init, search, scan etc. This stream should be used to allocate all
594 memory used for the response when thread safe operation is needed.
596 Changed the comstack utility, cs_addstr, to be thread safe. The
597 returned hostname string returned by the function is now part the
600 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
601 function. The cs_straddr takes a COMSTACK handle as argument, so this
602 function must be used after cs_create and before bind/connect.
603 This function is thread safe.
605 Moved test server to 'ztest' directory - generic server code still
606 in 'server' directory.
608 Made prefix query (pquery.c) utility thread safe.
610 Added new function modifier YAZ_EXPORT to 'export' public DLL
611 functions when using windows (see include/yconfig.h).
613 Added definitions to the OID database (util/oid.c) (RVDM).
615 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
617 Added call to ccl_rpn_delete in client program.
619 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
620 release of RPN structure.
622 Added support for C++, headers uses extern "C" for public definitions.
623 With input from RVDM.
625 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
626 Thanks to Ronald van der Meer (RVDM).
628 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
630 Added support for private extensions to the OID database
631 (oid_setprivateoids()). Thanks to RVDM.
633 Added optional, physical ANY (key replication)
635 Fixed null-reference problem in GRS-1 output filter.
637 Proximity operator added to Prefix Query Format (PQF).
639 In test client command "base" accepts multiple databases.
641 Fixed bug in cs_close stack that caused trouble with WINSOCK.
645 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
647 Smallish bug-fixes in the new encoders/decoders (explain).
649 Bug fixed in DeleteRequest.
651 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
653 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
655 Added SOIF syntax (using private OID for now) to retrieval module and client.
657 Added Update extended service.
659 Added SearchResult-1 additional info structure.
661 Added optional CCL (ISO8777) interpreter as separate module. Available
664 --- 1.2 1996/6/10 (1st anniversary release)
666 Added Summary record syntax. Lightly tested.
668 Added OPAC record syntax. Untested.
670 Added ResourceReport service encoders/decoders. Untested.
672 Fixed bug in z_Unit - wrong tagging on unitSystem.
674 Fixed bug in the DiagRecs decoder.
676 Added options for max PDU size and session timeout to frontend-server.
678 Added documentation of query-language parsers and other supporting utilities.
680 [frontend-server] Added Attribute set to the bend_scanrequest API.
682 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
683 surrogate diagnostics were generated.
685 [retrieval] Allow multiple local values for attribute.
687 [retrieval] Allow multiple attributes per element in .abs files. index type.
689 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
693 Minor changes, mostly specific to Zebra's requirements (retrieval)
697 Repaired bug in frontend server when running multiple listening
698 endpoints in dynamic mode.
700 z_External() now won't break if a known, ASN.1 value comes encapsulated
701 in an octet-string. The value will pass through unmodified in an Odr_oct.
703 Added a bit of code to the demo client to decode & display
704 ASN.1-structured records represented in the octet-aligned branch of
705 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
707 Added z_ext_getentbyref() to the ASN module. Doc updated.
709 * Completed the SCAN definition in the ASN module. This may break SCAN
710 code based on older YAZ-versions at compile-time. The fix is easy -
713 * Added 'displayTerm' and OtherInformation to the TermInfo structure
714 under the SCAN definition. Remember to initialize this, server-people.
716 Comstack should now support the WAIS protocol in TCP/IP mode. Note
717 that this does not extend to ODR and ASN.
719 Comstack allows insertion of established socket (primarily for
720 inetd-operation of servers). Doc updated.
722 Front-end server can now start from the inetd in TCP mode. Doc
729 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
730 the rank and record number.
732 Adjustments to the frontend server.
734 Fixed diagnostic BER dumper. It ignored the file argument.
738 Various changes to retrieval module.
740 Changed the union discriminators of the protocol files from enums to
741 ints paired with #defines.
743 *Changed oident.class to oident.oclass to avoid a reserved word in C++
746 *Changed operator in the RPN structure to 'roperator', again to avoid a
749 Fixed problems in Explain decoders/encoders.
753 Memory bug in log module fixed.
757 Occasional malloc() of 0 bytes fixed in d1_espec.c.
759 Bug in Explain DatabaseInfo module fixed.
761 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
765 The shift to v1.0 signals that we now consider the *core* functionality
766 of YAZ reasonably stable (the core being more or less equivalent to
767 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
768 tested (Explain not at all - though that will happen soonish).
770 Minor changes to code to support Windows port.
772 Various minor changes after we're getting to use GRS-1 & co. more.
774 Added Espec-1 format.
776 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
777 of the protocol and it cannot be selected when encoding (maps into 'string'
778 when decoding). Needed to talk to some servers.
780 Demo client can request simple element set names.
782 Added Diagnostic Format encoders/decoders.
784 Added simple Close handling to frontend server (no hooks for resource
785 reporting yet), and demonstration client.
787 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
791 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
792 handled incorrectly when records were requested in the searchResponse. This
793 will only affect you if you use the frontend-server.
795 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
796 Test-client will ask for and print GRS1. Ztest will return dummy records
799 Added Explain encoders/decoders to the service-level API. Untested.
801 Added Extended Services: Item Order encoders and decoders to the Service-
802 level API. Untested. We could use a recent copy of the pertinent bits
803 of the ILL protocol to add those bits.
805 Added diagnostic format 1 encoders/decoders to the service-level API.
808 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
809 odr_cons.c, which causes a more correct output.
811 Fixed handling of searchRequest in frontend server. NextResultSetPosition
812 was always set to 0 when no records were requested in the searchRequest.
814 * Added better external-handling. This shouldn't harm old code that
815 *encodes* externals. It can break code that looks for a
816 'single-ASN1-type' representation, since those types that are known
817 are now decoded immediately. Look at the SUTRS sample code in
818 seshigh.c and client.c. Documentation updated.
820 Handling of structured records in bend_fetchresponse. Length -1 marks
821 structured record, type is deduced from format field.
824 Fairly quick maintenance release to add SUTRS support.
826 Fixed handling of SUTRS records in the demonstration client.
828 * Added format field to the bend_fetchrequest and bend_fetchresponce
829 structures of the backend API (frontend server). When the record is
830 returned, the value of the format field is mapped to an OID. The
831 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
832 of the record. The special value VAL_NONE in the bend_request means
833 that no specific format was requested by the client. Documentation
834 updated accordingly. Test server (ztest) will return a fixed dummy
835 SUTRS record if your client requests SUTRS.
837 Documentation updated accordingly.
839 You can now set external libraries and RANLIB support in the top-level
843 First public release.
