1 Possible compatibility problems with earlier versions marked with '*'.
7 Added three members in bend_initrequest structure to facilitate
8 character set negotiation.
10 Fixed a bug in frontend server that could cause indefinite
11 loops under rare conditions.
13 Revised character set utilities (charneg.h) so that encoding
14 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
16 For PQF, directive @term <type> sets term type for Scan/Search.
17 Here <type> is general, string, numeric, null. The term type
18 is inherited - just like @attr.
20 New call odr_set_charset that sets character set conversion for
21 international-strings on a ODR stream. Prototype is:
22 int odr_set_charset(ODR o, const char *to, const char *from);
23 The InternationalString is still represented as C string in YAZ
24 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
25 won't). On the protocol level, you can use any encoding.
27 Support for UNIX sockets in ZOOM.
29 Solaris recv sometimes returns errno == ENOENT. It is treated as
30 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
32 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
33 both client and server. Code by Morten Bøgeskov.
37 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
38 that they can be used directly from Visual Basic. You must recompile
39 your windows APP if you're using ZOOM.
41 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
42 Commands "lang" and "charset" sets language and character set respectively.
43 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
44 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
46 Attributes from multiple CCL fields may be OR'ed rather than merged
47 using directive "@field or". Fields are still merged by default -
48 equivalent to "@field merge".
50 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
53 Fixed bug in zget for parameter ExtendedServicesResponse.
59 Added PQF feature: '@attr type=value' may be written as '@type=value'.
61 Client displays USR.1:SearchResult-1 (hits per term).
63 Additional Search Info for search in Generic Frontend Server.
65 Fixed CCL parsing of "field=s".
67 WIN32 installer - using the excellent NSIS software from nullsoft.
69 Fixed CCL parsing of "field = - <number>".
71 Added function yaz_marc_decode that decodes MARC for line mode
72 display or XML (similar to that used by JZKit).
74 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
75 Z39.50. But ISO/ILL was, however.
77 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
78 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

81 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
85 New YAZ client features: Command completion and new commands:
86 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
87 Code provided by Jacob Poulsen.
89 New call oid_trav, that visits all registered OIDs via callback.
91 Function ZOOM_record_get now returns const char pointer rather than
92 void pointer. It saves a lot of type casts.
94 For YAZ client, command "auth" now allows you to set authentication
95 in IdPass style. It is enabled when three tokens are given - order
96 is user, group and password.
98 Fix memory leaks in MARC record handling for ZOOM.
100 New option for YAZ client, -k <kilobytes> that sets
101 maximum record size. Similar to -k option for generic frontend
102 server and yaz-ztest.
104 More fixes for scan. Non-zero stepSize handled. OID's fixes.
106 Prefix query parser reports "fail" when bad attribute set is given.
108 Fix in MARC decoder. Proximity logging. Fix for attribute set
109 in scan handler for server. Patches by Shigeru Ishida.
111 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
114 Configure option --with-openssl=<dir> now works when a directory is
115 specified. Patch provided by Morten Bøgeskov.
117 New option for YAZ client, -u <auth>, that sets authentication.
119 ZOOM fix: error information was sometimes "missing", since error
120 was cleared/reset too when it shouldn't.
122 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
126 Scan for ZOOM API. New object ZOOM_scanset. New functions
127 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
128 ZOOM_scanset_destroy.
130 New ZOOM function, ZOOM_connection_last_event, that returns type
131 of last event (such as "receive data", "send data", "apdu received",
134 New ZOOM option, schema, that specifies shema OID for retrieval.
136 New CCL feature. Qualifiers can be aliases for one or more
137 other qualifiers (if more than one is given, OR is used).
139 ZOOM uses named result sets if target supports it.
141 Two new YAZ client commands: . (dot, which sources a script of YAZ
142 client commands), and ! (to execute shell command.). Implemented
145 Working on Debian packages.
149 YAZ client enables named result sets only if target supports it.
151 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
153 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
154 with key="host" to get same result.
156 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
157 Function Z3950_resultset_record(s) returns references to records
158 "owned" by resultset. To become owner use Z3950_record_clone.
160 Function z_ext_record handles Extended Services. Thanks to
165 CCL Parser fix: ignore token comma when dealing with and-lists.
167 Documentation updates for COMSTACK.
169 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
170 Changed prototype Z3950_records. For some functions, int parameters
171 were changed to size_t.
173 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
176 New MARC decode/display function, marc_display_exl, which properly rejects
177 non-ISO2709 records. YAZ client uses it.
181 Fix bug: local attribute set wasn't set correctly in PQF strings.
185 * Old Z39.50 codecs no longer supported.
187 Added ZOOM C binding. See http://zoom.z3950.org/
189 Renamed states for COMSTACKs to avoid confusion with events.
191 Implemented cs_look and proper cs_rcvconnect.
193 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
195 Configure detects POSIX threads on OpenBSD.
197 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
198 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
200 When error is returned from present handler, non-surrogate diagnostic
201 is returned in present response (and fetch handler is no longer called).
203 * Minor adjustments to pquery parser (PQF). Token characters may be
204 escaped by using backslash (C-style).
206 PQF parser allows string attribute values to be specified. For @attr,
207 non-numeric characters after the equal-sign are treated as strings
208 (e.g. @attr 9=title).
210 CCL trunction character may be defined (@truncation in file)
212 * function zget_ExtendedServicesRequest sets waitAction to
213 waitIfPossible (was wait).
215 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
218 CCL operator names may be set in field definition files (CCL_bibset).
219 See ccl/bib1 for an example.
221 Fixes in ASN.1 compiler for C++ compatibility.
223 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
224 and "op_or" to avoid conflict with C++.
226 Fixed problem with GNU readline detection on Redhat 7.0.
228 Added step-size for Scan backend handler.
230 Fixed bug that made the frontend server crash when no attribute
231 set was specified for scan.
233 Front-end server automatically switches to original working directory
234 when installed as an NT service. Previously -w had to be specified to
237 Added extended attributes for retrieval module (data1), so that data1
238 records carry d1_readXML/SGML attributes. d1_read also supports
239 null-data rules ( <tag/>)
241 On UNIX when POSIX threads are available, a separate library libyazthread
242 is created. Programmers should link with that library and the yaz library
243 when using threads. The reason for the split was that some applications
244 on Linux, such as Apache, doesn't work well when using shared objects that
247 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
248 (or any frontend server) in SSL mode by specifying ssl: followed by
249 address. Only tested on UNIX.
251 Added feature for CCL module. Virtual structure s=al or s=ol generates
252 and-list and or-list respectively instead of phrase search.
256 * Added prefix "yaz_" for the functions log_init.., log_file.. and
257 log_mask_str. This was done to avoid name conflicts with other libraries
258 (such as other PHP extensions).
260 Added raw OID member for preferred record syntax (request_format_raw)
261 and returned record syntax (output_format_raw) for backend fetch method.
263 Config file yaz-config now accepts options so that it returns specific
264 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
266 Shared library support for UNIX using GNU libtool.
268 * Modified backend interface. Request/Response struct's replaced by
269 one read/write C struct. For example bend_fetchrequest and
270 bend_fetchresult have been replaced by single bend_fetch_rr struct.
271 Every handler - even search has to be registered in bend_init
272 handler. This means that the YAZ library no longer refers to
273 external functions and it makes it possible to make the whole
274 thing a single DLL/SO.
276 Added Segment handler for backend server.
278 Added Zmbol/Zebra administrative functions to YAZ client.
280 Threaded frontend server on UNIX (when POSIX Threads are available).
281 Starting the server with option -T enables multi-threading.
285 Added configure option --enable-comp/disable-comp to control use
286 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
287 located in sub directory asn.
289 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
290 in ${exec_prefix}/bin along with the other programs yaz-client and
293 GNU automake used to maintain makefiles.
297 Changed retrieval module so that we can load records with no abstract
298 syntax defined. Tagpaths in these records are fully composed of string
301 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
305 On UNIX, the generated makefile now supports a proper 'make install'.
306 The prefix can be set via GNU configure to set the install location
307 (default is /usr/local).
309 * YAZ programs client and ztest were renamed to yaz-client and
310 yaz-ztest to avoid conflicts when users install YAZ in "standard"
311 locations, such as /usr/bin,/usr/local/bin,etc.
313 * YAZ Header files were moved from include to include/yaz. YAZ Header
314 files are referred to as include <yaz/log.h> rather than <log.h>.
315 The YAZ include path (-I ..) is therefore the same as before. Programmers
316 should update their #include statements or use -Ipath/include/yaz
317 instead. The main motivation for doing this change is that YAZ header files
318 can be installed in "standard" locations /usr/include,/usr/local/include
319 without introducing conflicts, since ALL YAZ header files are stored
320 in subdirectory yaz (under /usr/include for example).
322 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
323 rather than project/workspace files. We switched because project files
324 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
327 Changed name of logging function, logf, to yaz_log, to prevent name
328 clash with some math-log functions. The YAZ header log.h defines logf
329 to yaz_log (#define) so there should be no incompatibilities by this
332 Added bend_start/bend_stop handlers for server. These handler are
333 called on start/stop of server. For windows they are called whenever
334 a service is started/stopped.
336 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
337 a fairly small ASN.1 compiler written in Tcl. The compiler is located
338 in util/yc.tcl. The auto-generated C code structures are, in a few
339 cases, incompatible with the old decoders. There are differences in the
340 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
341 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
342 The preprocessor variable ASN_COMPILED is defined when the compiled
343 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
344 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
345 wish to use the old encoders/decoders you can specify --disable-yc
348 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
349 version so that it supports both new - and old version of DB Update
351 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
352 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
353 change. The name parameter can be set to 0 in which no name is specified
354 for the construction. The macros odr_implicit and odr_explicit sets name
355 parameter to zero for the construction involved. New macros
356 odr_implicit_tag and odr_explicit_tag are similar to the others,
357 except that a name parameter is added. For programmers' that don't use
358 ODR they probably only need to change the call to z_APDU and z_External.
360 Added access control facility by interfacing the TCP wrapper library.
361 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
362 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
363 name of the daemon and enables the access control as specified in
364 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
366 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
367 den Dool <H.M.vdnDool@kub.nl>.
369 Added reference ID parameter to most functions in server API - refer
370 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
372 Changed name of ccl library to libccl.a (was ccl.a).
374 Fixed bug in decoder for Explain (Category TargetInfo).
376 Added support for GNU readline in client. Thanks to Jacob Poulsen
377 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
379 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
380 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
381 IMPLEMENTATION! This change was made to the development version before
382 the ZIG decided to retract the amendment. If any users MUST be
383 compatible with the original Update definition, PLEASE CONTACT US, and
384 we will include a separate definition corresponding to the old Update
385 ES. Note that because of the change to the ASN.1 of the
386 TaskPackageRecordStructure we cannot define a single structure that
387 will support both versions.
389 * Added const modifier to buffer parameter for some ODR/BER encoding
390 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
391 completeWAIS, odr_dumpBER.
393 Fixed bug in client.c which caused a crash when a scanResponse didn't
394 contain positionOfTerm.
396 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
397 * will cause an error in a client if a non-YAZ target sends both a
398 * list of Scan entries and non-surrogate diagnostics.
400 Retrieval module enhancements. Tag sets may be typed in the reference
401 to it. From the .abs-file the "tagset" directive takes a third optional
402 integer type for the tag set referenced. From a .tag-file the "include"
403 directive takes a third optional type as well. The old "type" directive
404 in the tag set itself is still recognized but acts as the default type
407 Backend interface change. Individual Scan terms returned from bend_scan
408 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
409 in include/backend.h.
411 Retrieval module enhancements. Multiple tag sets and attribute sets may
412 be specified in abstract syntax specs. Revised the error/warning for
413 logging messages reported by the retrieval module when reading the
416 Object Identifier system (oid_..) changed. The API is backwards
417 compatible but the oid-routines now allocates new OID's when needed.
418 Raw OID's may be specified in oid_getvalbyname.
420 YAZ now uses GNU configure to generate Makefile(s).
422 * Minor changes in some of the member names of DeleteResultSetRequest and
423 DeleteResultSetResponse. See include/proto.h.
425 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
426 and added member 'languages' in TargetInfo (which was missing).
428 Changed the way attribute sets are handled in the retrieval
429 module. These are now cached, just like the abstract syntaxes
432 Changed YAZ so that it links with compiled ASN.1.
434 Added Explain-schema definitions and mapping routines. The following
435 Explain categories have been implemented: AttributeDetails,
436 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
438 Fixed minor bug in Windows version of Server Library.
440 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
442 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
444 Added EXTERNAL: UNIverse Resource Report (non-standard).
446 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
447 ENUMERATED and SET OF.
449 * Added 'const' to some of the char pointer arguments for the
450 functions, data1_read_node, data1_getelementbytagname,
451 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
454 Fixed bug in data1_insert_taggeddata - the last_child member of
455 parent wasn't initialised.
457 * Changed data1_read_record and data1_read_node so that the supplied
458 "SGML"-buffer is read-only. In particular the resulting data1 - tree
459 doesn't refer to any parts of the "SGML"-buffer.
461 Fixed bug in server library (Windows version of statserv_remove).
463 * Changed code so that it compiles as C++. The type definition
464 of Odr_fun which is a member of Odr_arm was changed. The result is,
465 that an explicit typecast is needed for the fun pointer when
466 using Odr_arm - as in:
467 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
469 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
471 Implemented the new structured date and time definition as approved
472 by the ZIG. Added schemaId element to the specificTag in Espec-1
473 (also approved at the last ZIG). Thanks to RVDM.
475 Added some Object identifiers (RVDM).
477 Changed the Update Extended Service (RVDM).
479 Added command "refid" to client which specifies referenceId for
480 the following requests.
482 Implemented extended service handling for server. See ztest.c
483 for an example as well as backend.h. New handlers are registerd
486 * Changed interface for sort in server.
488 Added new members to statserv_options_block. It allows a server
489 to read options from another source than just the command line. Thanks
490 to Charles Woodfield.
492 * Changed definition of Z_Triple in file prt-grs.h - member boolean
493 renamed to zboolean. Some C++ compilers complained about the name.
495 Minor changes to gils.abs. Added index 's' (sort) on title
496 and date/time-last-modified.
500 Fixed bug in server library regarding inetd mode (-i). This bug
501 was introduced by release 1.4.
505 Added sort facility in client and backend server interface.
507 Fixed problem with dependencies in Makefile(s).
509 Fixed bugs for encoders/decoders of extended services and
512 Implemented sub-tree feature for schemas. Sub-trees are
513 referenced in *.abs-files. See explain.abs for an example
514 of the use of this feature.
516 Modified bib1.att; local attributes for ANY didn't include
517 ANY itself (only affects use of the retrieval module).
519 Fixed bug in plain SGML reader in function data1_read_node:
520 tags with prefix "var" was incorrectly interpreted as variants.
522 Added feature "sub-schemas" to enable references to - and definitions
523 of - group of elements.
525 * Removed member parent from type data1_element (in data1.h).
527 Implemented function odr_nullval() that returns the value of
530 * Removed member num_children from data1_node (in data1.h).
532 Made NT service interface part of the server library. The
533 function statserv_main uses the NT service when required and
534 calls the statserv_start / statserv_close routines.
536 Routine zget_SearchRequest and zget_PresentRequest fills
537 resultSetName/Id member with "default" instead of "Default".
539 Fixed memory leak in server. Request queue member wasn't freed.
541 Fixed nmem_exit so that memory is freed.
545 Revised the CCL parser utility to be thread safe.
547 Added function, oid_ent_to_oid, to replace the function
548 oid_getoidbyent, which is not thread safe.
550 * Added nmem_init and nmem_exit to initialize and release
551 NMEM resources. Function nmem_init should be called once in the
552 initial thread before NMEM/ODR is used. statserv.c and client.c
553 have been changed accordingly. The change was necessary to make
554 NMEM thread safe. The NMEM memory pool is shared amongst threads
555 in a process. Unix-based applications will still work fine without
558 Added NT Services interface for the the Z39.50 (statserv) Server.
559 Refer to the ztest.c source on the usage.
561 Windows 95/NT port using MSVC5.0. Project files are included in the
564 * Defined new 'global' handle for the retrieval (data1) system. The
565 new handled, data1_handle, describes the state of the data1 system.
566 This handle is passed as first argument to virtually all
567 data1 related routines. The functions data1_create and data1_destroy
568 creates and destroys a data1 handle respectively.
570 Added ODR encode stream member to all backend request structures
571 init, search, scan etc. This stream should be used to allocate all
572 memory used for the response when thread safe operation is needed.
574 Changed the comstack utility, cs_addstr, to be thread safe. The
575 returned hostname string returned by the function is now part the
578 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
579 function. The cs_straddr takes a COMSTACK handle as argument, so this
580 function must be used after cs_create and before bind/connect.
581 This function is thread safe.
583 Moved test server to 'ztest' directory - generic server code still
584 in 'server' directory.
586 Made prefix query (pquery.c) utility thread safe.
588 Added new function modifier YAZ_EXPORT to 'export' public DLL
589 functions when using windows (see include/yconfig.h).
591 Added definitions to the OID database (util/oid.c) (RVDM).
593 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
595 Added call to ccl_rpn_delete in client program.
597 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
598 release of RPN structure.
600 Added support for C++, headers uses extern "C" for public definitions.
601 With input from RVDM.
603 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
604 Thanks to Ronald van der Meer (RVDM).
606 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
608 Added support for private extensions to the OID database
609 (oid_setprivateoids()). Thanks to RVDM.
611 Added optional, physical ANY (key replication)
613 Fixed null-reference problem in GRS-1 output filter.
615 Proximity operator added to Prefix Query Format (PQF).
617 In test client command "base" accepts multiple databases.
619 Fixed bug in cs_close stack that caused trouble with WINSOCK.
623 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
625 Smallish bug-fixes in the new encoders/decoders (explain).
627 Bug fixed in DeleteRequest.
629 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
631 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
633 Added SOIF syntax (using private OID for now) to retrieval module and client.
635 Added Update extended service.
637 Added SearchResult-1 additional info structure.
639 Added optional CCL (ISO8777) interpreter as separate module. Available
642 --- 1.2 1996/6/10 (1st anniversary release)
644 Added Summary record syntax. Lightly tested.
646 Added OPAC record syntax. Untested.
648 Added ResourceReport service encoders/decoders. Untested.
650 Fixed bug in z_Unit - wrong tagging on unitSystem.
652 Fixed bug in the DiagRecs decoder.
654 Added options for max PDU size and session timeout to frontend-server.
656 Added documentation of query-language parsers and other supporting utilities.
658 [frontend-server] Added Attribute set to the bend_scanrequest API.
660 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
661 surrogate diagnostics were generated.
663 [retrieval] Allow multiple local values for attribute.
665 [retrieval] Allow multiple attributes per element in .abs files. index type.
667 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
671 Minor changes, mostly specific to Zebra's requirements (retrieval)
675 Repaired bug in frontend server when running multiple listening
676 endpoints in dynamic mode.
678 z_External() now won't break if a known, ASN.1 value comes encapsulated
679 in an octet-string. The value will pass through unmodified in an Odr_oct.
681 Added a bit of code to the demo client to decode & display
682 ASN.1-structured records represented in the octet-aligned branch of
683 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
685 Added z_ext_getentbyref() to the ASN module. Doc updated.
687 * Completed the SCAN definition in the ASN module. This may break SCAN
688 code based on older YAZ-versions at compile-time. The fix is easy -
691 * Added 'displayTerm' and OtherInformation to the TermInfo structure
692 under the SCAN definition. Remember to initialize this, server-people.
694 Comstack should now support the WAIS protocol in TCP/IP mode. Note
695 that this does not extend to ODR and ASN.
697 Comstack allows insertion of established socket (primarily for
698 inetd-operation of servers). Doc updated.
700 Front-end server can now start from the inetd in TCP mode. Doc
707 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
708 the rank and record number.
710 Adjustments to the frontend server.
712 Fixed diagnostic BER dumper. It ignored the file argument.
716 Various changes to retrieval module.
718 Changed the union discriminators of the protocol files from enums to
719 ints paired with #defines.
721 *Changed oident.class to oident.oclass to avoid a reserved word in C++
724 *Changed operator in the RPN structure to 'roperator', again to avoid a
727 Fixed problems in Explain decoders/encoders.
731 Memory bug in log module fixed.
735 Occasional malloc() of 0 bytes fixed in d1_espec.c.
737 Bug in Explain DatabaseInfo module fixed.
739 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
743 The shift to v1.0 signals that we now consider the *core* functionality
744 of YAZ reasonably stable (the core being more or less equivalent to
745 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
746 tested (Explain not at all - though that will happen soonish).
748 Minor changes to code to support Windows port.
750 Various minor changes after we're getting to use GRS-1 & co. more.
752 Added Espec-1 format.
754 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
755 of the protocol and it cannot be selected when encoding (maps into 'string'
756 when decoding). Needed to talk to some servers.
758 Demo client can request simple element set names.
760 Added Diagnostic Format encoders/decoders.
762 Added simple Close handling to frontend server (no hooks for resource
763 reporting yet), and demonstration client.
765 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
769 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
770 handled incorrectly when records were requested in the searchResponse. This
771 will only affect you if you use the frontend-server.
773 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
774 Test-client will ask for and print GRS1. Ztest will return dummy records
777 Added Explain encoders/decoders to the service-level API. Untested.
779 Added Extended Services: Item Order encoders and decoders to the Service-
780 level API. Untested. We could use a recent copy of the pertinent bits
781 of the ILL protocol to add those bits.
783 Added diagnostic format 1 encoders/decoders to the service-level API.
786 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
787 odr_cons.c, which causes a more correct output.
789 Fixed handling of searchRequest in frontend server. NextResultSetPosition
790 was always set to 0 when no records were requested in the searchRequest.
792 * Added better external-handling. This shouldn't harm old code that
793 *encodes* externals. It can break code that looks for a
794 'single-ASN1-type' representation, since those types that are known
795 are now decoded immediately. Look at the SUTRS sample code in
796 seshigh.c and client.c. Documentation updated.
798 Handling of structured records in bend_fetchresponse. Length -1 marks
799 structured record, type is deduced from format field.
802 Fairly quick maintenance release to add SUTRS support.
804 Fixed handling of SUTRS records in the demonstration client.
806 * Added format field to the bend_fetchrequest and bend_fetchresponce
807 structures of the backend API (frontend server). When the record is
808 returned, the value of the format field is mapped to an OID. The
809 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
810 of the record. The special value VAL_NONE in the bend_request means
811 that no specific format was requested by the client. Documentation
812 updated accordingly. Test server (ztest) will return a fixed dummy
813 SUTRS record if your client requests SUTRS.
815 Documentation updated accordingly.
817 You can now set external libraries and RANLIB support in the top-level
821 First public release.
