1 Possible compatibility problems with earlier versions marked with '*'.
5 Fixed ZOOM C record cache so that preferredRecordSyntax and
6 elementSetName is used to check for already fetched records.
10 Added three members in bend_initrequest structure to facilitate
11 character set negotiation.
13 Fixed a bug in frontend server that could cause indefinite
14 loops under rare conditions.
16 Revised character set utilities (charneg.h) so that encoding
17 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
19 For PQF, directive @term <type> sets term type for Scan/Search.
20 Here <type> is general, string, numeric, null. The term type
21 is inherited - just like @attr.
23 New call odr_set_charset that sets character set conversion for
24 international-strings on a ODR stream. Prototype is:
25 int odr_set_charset(ODR o, const char *to, const char *from);
26 The InternationalString is still represented as C string in YAZ
27 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
28 won't). On the protocol level, you can use any encoding.
30 Support for UNIX sockets in ZOOM.
32 Solaris recv sometimes returns errno == ENOENT. It is treated as
33 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
35 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
36 both client and server. Code by Morten Bøgeskov.
40 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
41 that they can be used directly from Visual Basic. You must recompile
42 your windows APP if you're using ZOOM.
44 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
45 Commands "lang" and "charset" sets language and character set respectively.
46 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
47 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
49 Attributes from multiple CCL fields may be OR'ed rather than merged
50 using directive "@field or". Fields are still merged by default -
51 equivalent to "@field merge".
53 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
56 Fixed bug in zget for parameter ExtendedServicesResponse.
62 Added PQF feature: '@attr type=value' may be written as '@type=value'.
64 Client displays USR.1:SearchResult-1 (hits per term).
66 Additional Search Info for search in Generic Frontend Server.
68 Fixed CCL parsing of "field=s".
70 WIN32 installer - using the excellent NSIS software from nullsoft.
72 Fixed CCL parsing of "field = - <number>".
74 Added function yaz_marc_decode that decodes MARC for line mode
75 display or XML (similar to that used by JZKit).
77 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
78 Z39.50. But ISO/ILL was, however.
80 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
81 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
83 http://lcweb.loc.gov/z3950/agency/amend/am2.html
84 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
88 New YAZ client features: Command completion and new commands:
89 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
90 Code provided by Jacob Poulsen.
92 New call oid_trav, that visits all registered OIDs via callback.
94 Function ZOOM_record_get now returns const char pointer rather than
95 void pointer. It saves a lot of type casts.
97 For YAZ client, command "auth" now allows you to set authentication
98 in IdPass style. It is enabled when three tokens are given - order
99 is user, group and password.
101 Fix memory leaks in MARC record handling for ZOOM.
103 New option for YAZ client, -k <kilobytes> that sets
104 maximum record size. Similar to -k option for generic frontend
105 server and yaz-ztest.
107 More fixes for scan. Non-zero stepSize handled. OID's fixes.
109 Prefix query parser reports "fail" when bad attribute set is given.
111 Fix in MARC decoder. Proximity logging. Fix for attribute set
112 in scan handler for server. Patches by Shigeru Ishida.
114 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
117 Configure option --with-openssl=<dir> now works when a directory is
118 specified. Patch provided by Morten Bøgeskov.
120 New option for YAZ client, -u <auth>, that sets authentication.
122 ZOOM fix: error information was sometimes "missing", since error
123 was cleared/reset too when it shouldn't.
125 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
129 Scan for ZOOM API. New object ZOOM_scanset. New functions
130 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
131 ZOOM_scanset_destroy.
133 New ZOOM function, ZOOM_connection_last_event, that returns type
134 of last event (such as "receive data", "send data", "apdu received",
137 New ZOOM option, schema, that specifies shema OID for retrieval.
139 New CCL feature. Qualifiers can be aliases for one or more
140 other qualifiers (if more than one is given, OR is used).
142 ZOOM uses named result sets if target supports it.
144 Two new YAZ client commands: . (dot, which sources a script of YAZ
145 client commands), and ! (to execute shell command.). Implemented
148 Working on Debian packages.
152 YAZ client enables named result sets only if target supports it.
154 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
156 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
157 with key="host" to get same result.
159 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
160 Function Z3950_resultset_record(s) returns references to records
161 "owned" by resultset. To become owner use Z3950_record_clone.
163 Function z_ext_record handles Extended Services. Thanks to
168 CCL Parser fix: ignore token comma when dealing with and-lists.
170 Documentation updates for COMSTACK.
172 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
173 Changed prototype Z3950_records. For some functions, int parameters
174 were changed to size_t.
176 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
179 New MARC decode/display function, marc_display_exl, which properly rejects
180 non-ISO2709 records. YAZ client uses it.
184 Fix bug: local attribute set wasn't set correctly in PQF strings.
188 * Old Z39.50 codecs no longer supported.
190 Added ZOOM C binding. See http://zoom.z3950.org/
192 Renamed states for COMSTACKs to avoid confusion with events.
194 Implemented cs_look and proper cs_rcvconnect.
196 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
198 Configure detects POSIX threads on OpenBSD.
200 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
201 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
203 When error is returned from present handler, non-surrogate diagnostic
204 is returned in present response (and fetch handler is no longer called).
206 * Minor adjustments to pquery parser (PQF). Token characters may be
207 escaped by using backslash (C-style).
209 PQF parser allows string attribute values to be specified. For @attr,
210 non-numeric characters after the equal-sign are treated as strings
211 (e.g. @attr 9=title).
213 CCL trunction character may be defined (@truncation in file)
215 * function zget_ExtendedServicesRequest sets waitAction to
216 waitIfPossible (was wait).
218 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
221 CCL operator names may be set in field definition files (CCL_bibset).
222 See ccl/bib1 for an example.
224 Fixes in ASN.1 compiler for C++ compatibility.
226 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
227 and "op_or" to avoid conflict with C++.
229 Fixed problem with GNU readline detection on Redhat 7.0.
231 Added step-size for Scan backend handler.
233 Fixed bug that made the frontend server crash when no attribute
234 set was specified for scan.
236 Front-end server automatically switches to original working directory
237 when installed as an NT service. Previously -w had to be specified to
240 Added extended attributes for retrieval module (data1), so that data1
241 records carry d1_readXML/SGML attributes. d1_read also supports
242 null-data rules ( <tag/>)
244 On UNIX when POSIX threads are available, a separate library libyazthread
245 is created. Programmers should link with that library and the yaz library
246 when using threads. The reason for the split was that some applications
247 on Linux, such as Apache, doesn't work well when using shared objects that
250 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
251 (or any frontend server) in SSL mode by specifying ssl: followed by
252 address. Only tested on UNIX.
254 Added feature for CCL module. Virtual structure s=al or s=ol generates
255 and-list and or-list respectively instead of phrase search.
259 * Added prefix "yaz_" for the functions log_init.., log_file.. and
260 log_mask_str. This was done to avoid name conflicts with other libraries
261 (such as other PHP extensions).
263 Added raw OID member for preferred record syntax (request_format_raw)
264 and returned record syntax (output_format_raw) for backend fetch method.
266 Config file yaz-config now accepts options so that it returns specific
267 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
269 Shared library support for UNIX using GNU libtool.
271 * Modified backend interface. Request/Response struct's replaced by
272 one read/write C struct. For example bend_fetchrequest and
273 bend_fetchresult have been replaced by single bend_fetch_rr struct.
274 Every handler - even search has to be registered in bend_init
275 handler. This means that the YAZ library no longer refers to
276 external functions and it makes it possible to make the whole
277 thing a single DLL/SO.
279 Added Segment handler for backend server.
281 Added Zmbol/Zebra administrative functions to YAZ client.
283 Threaded frontend server on UNIX (when POSIX Threads are available).
284 Starting the server with option -T enables multi-threading.
288 Added configure option --enable-comp/disable-comp to control use
289 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
290 located in sub directory asn.
292 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
293 in ${exec_prefix}/bin along with the other programs yaz-client and
296 GNU automake used to maintain makefiles.
300 Changed retrieval module so that we can load records with no abstract
301 syntax defined. Tagpaths in these records are fully composed of string
304 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
308 On UNIX, the generated makefile now supports a proper 'make install'.
309 The prefix can be set via GNU configure to set the install location
310 (default is /usr/local).
312 * YAZ programs client and ztest were renamed to yaz-client and
313 yaz-ztest to avoid conflicts when users install YAZ in "standard"
314 locations, such as /usr/bin,/usr/local/bin,etc.
316 * YAZ Header files were moved from include to include/yaz. YAZ Header
317 files are referred to as include <yaz/log.h> rather than <log.h>.
318 The YAZ include path (-I ..) is therefore the same as before. Programmers
319 should update their #include statements or use -Ipath/include/yaz
320 instead. The main motivation for doing this change is that YAZ header files
321 can be installed in "standard" locations /usr/include,/usr/local/include
322 without introducing conflicts, since ALL YAZ header files are stored
323 in subdirectory yaz (under /usr/include for example).
325 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
326 rather than project/workspace files. We switched because project files
327 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
330 Changed name of logging function, logf, to yaz_log, to prevent name
331 clash with some math-log functions. The YAZ header log.h defines logf
332 to yaz_log (#define) so there should be no incompatibilities by this
335 Added bend_start/bend_stop handlers for server. These handler are
336 called on start/stop of server. For windows they are called whenever
337 a service is started/stopped.
339 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
340 a fairly small ASN.1 compiler written in Tcl. The compiler is located
341 in util/yc.tcl. The auto-generated C code structures are, in a few
342 cases, incompatible with the old decoders. There are differences in the
343 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
344 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
345 The preprocessor variable ASN_COMPILED is defined when the compiled
346 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
347 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
348 wish to use the old encoders/decoders you can specify --disable-yc
351 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
352 version so that it supports both new - and old version of DB Update
354 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
355 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
356 change. The name parameter can be set to 0 in which no name is specified
357 for the construction. The macros odr_implicit and odr_explicit sets name
358 parameter to zero for the construction involved. New macros
359 odr_implicit_tag and odr_explicit_tag are similar to the others,
360 except that a name parameter is added. For programmers' that don't use
361 ODR they probably only need to change the call to z_APDU and z_External.
363 Added access control facility by interfacing the TCP wrapper library.
364 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
365 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
366 name of the daemon and enables the access control as specified in
367 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
369 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
370 den Dool <H.M.vdnDool@kub.nl>.
372 Added reference ID parameter to most functions in server API - refer
373 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
375 Changed name of ccl library to libccl.a (was ccl.a).
377 Fixed bug in decoder for Explain (Category TargetInfo).
379 Added support for GNU readline in client. Thanks to Jacob Poulsen
380 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
382 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
383 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
384 IMPLEMENTATION! This change was made to the development version before
385 the ZIG decided to retract the amendment. If any users MUST be
386 compatible with the original Update definition, PLEASE CONTACT US, and
387 we will include a separate definition corresponding to the old Update
388 ES. Note that because of the change to the ASN.1 of the
389 TaskPackageRecordStructure we cannot define a single structure that
390 will support both versions.
392 * Added const modifier to buffer parameter for some ODR/BER encoding
393 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
394 completeWAIS, odr_dumpBER.
396 Fixed bug in client.c which caused a crash when a scanResponse didn't
397 contain positionOfTerm.
399 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
400 * will cause an error in a client if a non-YAZ target sends both a
401 * list of Scan entries and non-surrogate diagnostics.
403 Retrieval module enhancements. Tag sets may be typed in the reference
404 to it. From the .abs-file the "tagset" directive takes a third optional
405 integer type for the tag set referenced. From a .tag-file the "include"
406 directive takes a third optional type as well. The old "type" directive
407 in the tag set itself is still recognized but acts as the default type
410 Backend interface change. Individual Scan terms returned from bend_scan
411 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
412 in include/backend.h.
414 Retrieval module enhancements. Multiple tag sets and attribute sets may
415 be specified in abstract syntax specs. Revised the error/warning for
416 logging messages reported by the retrieval module when reading the
419 Object Identifier system (oid_..) changed. The API is backwards
420 compatible but the oid-routines now allocates new OID's when needed.
421 Raw OID's may be specified in oid_getvalbyname.
423 YAZ now uses GNU configure to generate Makefile(s).
425 * Minor changes in some of the member names of DeleteResultSetRequest and
426 DeleteResultSetResponse. See include/proto.h.
428 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
429 and added member 'languages' in TargetInfo (which was missing).
431 Changed the way attribute sets are handled in the retrieval
432 module. These are now cached, just like the abstract syntaxes
435 Changed YAZ so that it links with compiled ASN.1.
437 Added Explain-schema definitions and mapping routines. The following
438 Explain categories have been implemented: AttributeDetails,
439 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
441 Fixed minor bug in Windows version of Server Library.
443 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
445 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
447 Added EXTERNAL: UNIverse Resource Report (non-standard).
449 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
450 ENUMERATED and SET OF.
452 * Added 'const' to some of the char pointer arguments for the
453 functions, data1_read_node, data1_getelementbytagname,
454 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
457 Fixed bug in data1_insert_taggeddata - the last_child member of
458 parent wasn't initialised.
460 * Changed data1_read_record and data1_read_node so that the supplied
461 "SGML"-buffer is read-only. In particular the resulting data1 - tree
462 doesn't refer to any parts of the "SGML"-buffer.
464 Fixed bug in server library (Windows version of statserv_remove).
466 * Changed code so that it compiles as C++. The type definition
467 of Odr_fun which is a member of Odr_arm was changed. The result is,
468 that an explicit typecast is needed for the fun pointer when
469 using Odr_arm - as in:
470 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
472 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
474 Implemented the new structured date and time definition as approved
475 by the ZIG. Added schemaId element to the specificTag in Espec-1
476 (also approved at the last ZIG). Thanks to RVDM.
478 Added some Object identifiers (RVDM).
480 Changed the Update Extended Service (RVDM).
482 Added command "refid" to client which specifies referenceId for
483 the following requests.
485 Implemented extended service handling for server. See ztest.c
486 for an example as well as backend.h. New handlers are registerd
489 * Changed interface for sort in server.
491 Added new members to statserv_options_block. It allows a server
492 to read options from another source than just the command line. Thanks
493 to Charles Woodfield.
495 * Changed definition of Z_Triple in file prt-grs.h - member boolean
496 renamed to zboolean. Some C++ compilers complained about the name.
498 Minor changes to gils.abs. Added index 's' (sort) on title
499 and date/time-last-modified.
503 Fixed bug in server library regarding inetd mode (-i). This bug
504 was introduced by release 1.4.
508 Added sort facility in client and backend server interface.
510 Fixed problem with dependencies in Makefile(s).
512 Fixed bugs for encoders/decoders of extended services and
515 Implemented sub-tree feature for schemas. Sub-trees are
516 referenced in *.abs-files. See explain.abs for an example
517 of the use of this feature.
519 Modified bib1.att; local attributes for ANY didn't include
520 ANY itself (only affects use of the retrieval module).
522 Fixed bug in plain SGML reader in function data1_read_node:
523 tags with prefix "var" was incorrectly interpreted as variants.
525 Added feature "sub-schemas" to enable references to - and definitions
526 of - group of elements.
528 * Removed member parent from type data1_element (in data1.h).
530 Implemented function odr_nullval() that returns the value of
533 * Removed member num_children from data1_node (in data1.h).
535 Made NT service interface part of the server library. The
536 function statserv_main uses the NT service when required and
537 calls the statserv_start / statserv_close routines.
539 Routine zget_SearchRequest and zget_PresentRequest fills
540 resultSetName/Id member with "default" instead of "Default".
542 Fixed memory leak in server. Request queue member wasn't freed.
544 Fixed nmem_exit so that memory is freed.
548 Revised the CCL parser utility to be thread safe.
550 Added function, oid_ent_to_oid, to replace the function
551 oid_getoidbyent, which is not thread safe.
553 * Added nmem_init and nmem_exit to initialize and release
554 NMEM resources. Function nmem_init should be called once in the
555 initial thread before NMEM/ODR is used. statserv.c and client.c
556 have been changed accordingly. The change was necessary to make
557 NMEM thread safe. The NMEM memory pool is shared amongst threads
558 in a process. Unix-based applications will still work fine without
561 Added NT Services interface for the the Z39.50 (statserv) Server.
562 Refer to the ztest.c source on the usage.
564 Windows 95/NT port using MSVC5.0. Project files are included in the
567 * Defined new 'global' handle for the retrieval (data1) system. The
568 new handled, data1_handle, describes the state of the data1 system.
569 This handle is passed as first argument to virtually all
570 data1 related routines. The functions data1_create and data1_destroy
571 creates and destroys a data1 handle respectively.
573 Added ODR encode stream member to all backend request structures
574 init, search, scan etc. This stream should be used to allocate all
575 memory used for the response when thread safe operation is needed.
577 Changed the comstack utility, cs_addstr, to be thread safe. The
578 returned hostname string returned by the function is now part the
581 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
582 function. The cs_straddr takes a COMSTACK handle as argument, so this
583 function must be used after cs_create and before bind/connect.
584 This function is thread safe.
586 Moved test server to 'ztest' directory - generic server code still
587 in 'server' directory.
589 Made prefix query (pquery.c) utility thread safe.
591 Added new function modifier YAZ_EXPORT to 'export' public DLL
592 functions when using windows (see include/yconfig.h).
594 Added definitions to the OID database (util/oid.c) (RVDM).
596 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
598 Added call to ccl_rpn_delete in client program.
600 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
601 release of RPN structure.
603 Added support for C++, headers uses extern "C" for public definitions.
604 With input from RVDM.
606 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
607 Thanks to Ronald van der Meer (RVDM).
609 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
611 Added support for private extensions to the OID database
612 (oid_setprivateoids()). Thanks to RVDM.
614 Added optional, physical ANY (key replication)
616 Fixed null-reference problem in GRS-1 output filter.
618 Proximity operator added to Prefix Query Format (PQF).
620 In test client command "base" accepts multiple databases.
622 Fixed bug in cs_close stack that caused trouble with WINSOCK.
626 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
628 Smallish bug-fixes in the new encoders/decoders (explain).
630 Bug fixed in DeleteRequest.
632 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
634 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
636 Added SOIF syntax (using private OID for now) to retrieval module and client.
638 Added Update extended service.
640 Added SearchResult-1 additional info structure.
642 Added optional CCL (ISO8777) interpreter as separate module. Available
645 --- 1.2 1996/6/10 (1st anniversary release)
647 Added Summary record syntax. Lightly tested.
649 Added OPAC record syntax. Untested.
651 Added ResourceReport service encoders/decoders. Untested.
653 Fixed bug in z_Unit - wrong tagging on unitSystem.
655 Fixed bug in the DiagRecs decoder.
657 Added options for max PDU size and session timeout to frontend-server.
659 Added documentation of query-language parsers and other supporting utilities.
661 [frontend-server] Added Attribute set to the bend_scanrequest API.
663 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
664 surrogate diagnostics were generated.
666 [retrieval] Allow multiple local values for attribute.
668 [retrieval] Allow multiple attributes per element in .abs files. index type.
670 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
674 Minor changes, mostly specific to Zebra's requirements (retrieval)
678 Repaired bug in frontend server when running multiple listening
679 endpoints in dynamic mode.
681 z_External() now won't break if a known, ASN.1 value comes encapsulated
682 in an octet-string. The value will pass through unmodified in an Odr_oct.
684 Added a bit of code to the demo client to decode & display
685 ASN.1-structured records represented in the octet-aligned branch of
686 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
688 Added z_ext_getentbyref() to the ASN module. Doc updated.
690 * Completed the SCAN definition in the ASN module. This may break SCAN
691 code based on older YAZ-versions at compile-time. The fix is easy -
694 * Added 'displayTerm' and OtherInformation to the TermInfo structure
695 under the SCAN definition. Remember to initialize this, server-people.
697 Comstack should now support the WAIS protocol in TCP/IP mode. Note
698 that this does not extend to ODR and ASN.
700 Comstack allows insertion of established socket (primarily for
701 inetd-operation of servers). Doc updated.
703 Front-end server can now start from the inetd in TCP mode. Doc
710 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
711 the rank and record number.
713 Adjustments to the frontend server.
715 Fixed diagnostic BER dumper. It ignored the file argument.
719 Various changes to retrieval module.
721 Changed the union discriminators of the protocol files from enums to
722 ints paired with #defines.
724 *Changed oident.class to oident.oclass to avoid a reserved word in C++
727 *Changed operator in the RPN structure to 'roperator', again to avoid a
730 Fixed problems in Explain decoders/encoders.
734 Memory bug in log module fixed.
738 Occasional malloc() of 0 bytes fixed in d1_espec.c.
740 Bug in Explain DatabaseInfo module fixed.
742 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
746 The shift to v1.0 signals that we now consider the *core* functionality
747 of YAZ reasonably stable (the core being more or less equivalent to
748 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
749 tested (Explain not at all - though that will happen soonish).
751 Minor changes to code to support Windows port.
753 Various minor changes after we're getting to use GRS-1 & co. more.
755 Added Espec-1 format.
757 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
758 of the protocol and it cannot be selected when encoding (maps into 'string'
759 when decoding). Needed to talk to some servers.
761 Demo client can request simple element set names.
763 Added Diagnostic Format encoders/decoders.
765 Added simple Close handling to frontend server (no hooks for resource
766 reporting yet), and demonstration client.
768 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
772 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
773 handled incorrectly when records were requested in the searchResponse. This
774 will only affect you if you use the frontend-server.
776 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
777 Test-client will ask for and print GRS1. Ztest will return dummy records
780 Added Explain encoders/decoders to the service-level API. Untested.
782 Added Extended Services: Item Order encoders and decoders to the Service-
783 level API. Untested. We could use a recent copy of the pertinent bits
784 of the ILL protocol to add those bits.
786 Added diagnostic format 1 encoders/decoders to the service-level API.
789 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
790 odr_cons.c, which causes a more correct output.
792 Fixed handling of searchRequest in frontend server. NextResultSetPosition
793 was always set to 0 when no records were requested in the searchRequest.
795 * Added better external-handling. This shouldn't harm old code that
796 *encodes* externals. It can break code that looks for a
797 'single-ASN1-type' representation, since those types that are known
798 are now decoded immediately. Look at the SUTRS sample code in
799 seshigh.c and client.c. Documentation updated.
801 Handling of structured records in bend_fetchresponse. Length -1 marks
802 structured record, type is deduced from format field.
805 Fairly quick maintenance release to add SUTRS support.
807 Fixed handling of SUTRS records in the demonstration client.
809 * Added format field to the bend_fetchrequest and bend_fetchresponce
810 structures of the backend API (frontend server). When the record is
811 returned, the value of the format field is mapped to an OID. The
812 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
813 of the record. The special value VAL_NONE in the bend_request means
814 that no specific format was requested by the client. Documentation
815 updated accordingly. Test server (ztest) will return a fixed dummy
816 SUTRS record if your client requests SUTRS.
818 Documentation updated accordingly.
820 You can now set external libraries and RANLIB support in the top-level
824 First public release.
