1 Possible compatibility problems with earlier versions marked with '*'.
5 Fixed problem with C compiler include path in wrong order.
7 Support for SRW 1.0 over HTTP. This is an optional feature and
8 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
11 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
13 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
14 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
16 ZOOM connections are SRW based if host/port is specified
17 as http. e.g. z = ZOOM_connection_new("http://myserver");
18 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
20 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
21 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
22 distance=n, order=true/false, relation=le, prox unit=word. If
23 n is omitted, distance 1 is used.
25 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
26 on Solaris. Patch from Ko van der Sloot.
28 New MARC decode API. All new functions operate on a yaz_marc_t
29 handle. The most important new functions are: yaz_marc_create,
30 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
31 decode and destroy respectively. Decoder can produce formats
32 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
33 include/yaz/marcdisp.h.
35 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
36 to UTF-8, UCS-32, wchar_t or Latin-1.
38 * Prototypes for yaz_iconv_-functions moved to separate header
39 include/yaz/yaz-iconv.h.
41 Make a few private functions 'static' in unix.c. This prevents
42 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
44 For ZOOM connection, the options targetImplementation{Id,Name,Version}
45 are set when Init Response is received.
47 New function ZOOM_connection_error_x similar to ZOOM_connection_error
48 but returns diagnostic set as well.
50 New function yaz_strerror which is a portable wrapper for
51 strerror/strerror_r/GetLastMessage.
53 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
54 is returned for MARC. If type is "oai", then OAI MARC is returned.
56 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
61 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
63 Fix bad race conditions on SIGTERM and terminate gracefully in
66 Move retrieval (data1) module to Zebra since nobody seems to be
69 Add GRS-1 render for ZOOM using same format as yaz-client.
73 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
75 Fix broken ESpec handling in data1 module.
77 SGML reader parses comments and makes them part of the data1 tree.
79 Added several type casts so that YAZ compiles as C++ code.
81 ZOOM didn't handle PDU encoding failures properly.
83 Added more Bib-1 diagnostics (approved extensions).
85 GNU configure: better check for iconv.
87 More portable use of accept, getpeername. Check for socklen_t. Use
88 int/size_t if socklen_t is not defined.
92 PQF parser rejects bad queries - including those with extra
93 characters in them. PQF parser used to silently ignore that.
94 Cleaner API for PQF added, which allows you to get detailed
95 error information for bad queries (see yaz/pquery.h).
97 Fixed bug in ZOOM_record_get for type "database".
99 Implemented mini iconv library supporting conversions between
100 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
102 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
106 Fixed ZOOM C record cache so that preferredRecordSyntax and
107 elementSetName is used to check for already fetched records.
111 Added three members in bend_initrequest structure to facilitate
112 character set negotiation.
114 Fixed a bug in frontend server that could cause indefinite
115 loops under rare conditions.
117 Revised character set utilities (charneg.h) so that encoding
118 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
120 For PQF, directive @term <type> sets term type for Scan/Search.
121 Here <type> is general, string, numeric, null. The term type
122 is inherited - just like @attr.
124 New call odr_set_charset that sets character set conversion for
125 international-strings on a ODR stream. Prototype is:
126 int odr_set_charset(ODR o, const char *to, const char *from);
127 The InternationalString is still represented as C string in YAZ
128 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
129 won't). On the protocol level, you can use any encoding.
131 Support for UNIX sockets in ZOOM.
133 Solaris recv sometimes returns errno == ENOENT. It is treated as
134 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
136 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
137 both client and server. Code by Morten Bøgeskov.
141 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
142 that they can be used directly from Visual Basic. You must recompile
143 your windows APP if you're using ZOOM.
145 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
146 Commands "lang" and "charset" sets language and character set respectively.
147 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
148 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
150 Attributes from multiple CCL fields may be OR'ed rather than merged
151 using directive "@field or". Fields are still merged by default -
152 equivalent to "@field merge".
154 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
157 Fixed bug in zget for parameter ExtendedServicesResponse.
163 Added PQF feature: '@attr type=value' may be written as '@type=value'.
165 Client displays USR.1:SearchResult-1 (hits per term).
167 Additional Search Info for search in Generic Frontend Server.
169 Fixed CCL parsing of "field=s".
171 WIN32 installer - using the excellent NSIS software from nullsoft.
173 Fixed CCL parsing of "field = - <number>".
175 Added function yaz_marc_decode that decodes MARC for line mode
176 display or XML (similar to that used by JZKit).
178 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
179 Z39.50. But ISO/ILL was, however.
181 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
182 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
184 http://lcweb.loc.gov/z3950/agency/amend/am2.html
185 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
189 New YAZ client features: Command completion and new commands:
190 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
191 Code provided by Jacob Poulsen.
193 New call oid_trav, that visits all registered OIDs via callback.
195 Function ZOOM_record_get now returns const char pointer rather than
196 void pointer. It saves a lot of type casts.
198 For YAZ client, command "auth" now allows you to set authentication
199 in IdPass style. It is enabled when three tokens are given - order
200 is user, group and password.
202 Fix memory leaks in MARC record handling for ZOOM.
204 New option for YAZ client, -k <kilobytes> that sets
205 maximum record size. Similar to -k option for generic frontend
206 server and yaz-ztest.
208 More fixes for scan. Non-zero stepSize handled. OID's fixes.
210 Prefix query parser reports "fail" when bad attribute set is given.
212 Fix in MARC decoder. Proximity logging. Fix for attribute set
213 in scan handler for server. Patches by Shigeru Ishida.
215 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
218 Configure option --with-openssl=<dir> now works when a directory is
219 specified. Patch provided by Morten Bøgeskov.
221 New option for YAZ client, -u <auth>, that sets authentication.
223 ZOOM fix: error information was sometimes "missing", since error
224 was cleared/reset too when it shouldn't.
226 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
230 Scan for ZOOM API. New object ZOOM_scanset. New functions
231 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
232 ZOOM_scanset_destroy.
234 New ZOOM function, ZOOM_connection_last_event, that returns type
235 of last event (such as "receive data", "send data", "apdu received",
238 New ZOOM option, schema, that specifies shema OID for retrieval.
240 New CCL feature. Qualifiers can be aliases for one or more
241 other qualifiers (if more than one is given, OR is used).
243 ZOOM uses named result sets if target supports it.
245 Two new YAZ client commands: . (dot, which sources a script of YAZ
246 client commands), and ! (to execute shell command.). Implemented
249 Working on Debian packages.
253 YAZ client enables named result sets only if target supports it.
255 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
257 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
258 with key="host" to get same result.
260 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
261 Function Z3950_resultset_record(s) returns references to records
262 "owned" by resultset. To become owner use Z3950_record_clone.
264 Function z_ext_record handles Extended Services. Thanks to
269 CCL Parser fix: ignore token comma when dealing with and-lists.
271 Documentation updates for COMSTACK.
273 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
274 Changed prototype Z3950_records. For some functions, int parameters
275 were changed to size_t.
277 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
280 New MARC decode/display function, marc_display_exl, which properly rejects
281 non-ISO2709 records. YAZ client uses it.
285 Fix bug: local attribute set wasn't set correctly in PQF strings.
289 * Old Z39.50 codecs no longer supported.
291 Added ZOOM C binding. See http://zoom.z3950.org/
293 Renamed states for COMSTACKs to avoid confusion with events.
295 Implemented cs_look and proper cs_rcvconnect.
297 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
299 Configure detects POSIX threads on OpenBSD.
301 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
302 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
304 When error is returned from present handler, non-surrogate diagnostic
305 is returned in present response (and fetch handler is no longer called).
307 * Minor adjustments to pquery parser (PQF). Token characters may be
308 escaped by using backslash (C-style).
310 PQF parser allows string attribute values to be specified. For @attr,
311 non-numeric characters after the equal-sign are treated as strings
312 (e.g. @attr 9=title).
314 CCL trunction character may be defined (@truncation in file)
316 * function zget_ExtendedServicesRequest sets waitAction to
317 waitIfPossible (was wait).
319 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
322 CCL operator names may be set in field definition files (CCL_bibset).
323 See ccl/bib1 for an example.
325 Fixes in ASN.1 compiler for C++ compatibility.
327 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
328 and "op_or" to avoid conflict with C++.
330 Fixed problem with GNU readline detection on Redhat 7.0.
332 Added step-size for Scan backend handler.
334 Fixed bug that made the frontend server crash when no attribute
335 set was specified for scan.
337 Front-end server automatically switches to original working directory
338 when installed as an NT service. Previously -w had to be specified to
341 Added extended attributes for retrieval module (data1), so that data1
342 records carry d1_readXML/SGML attributes. d1_read also supports
343 null-data rules ( <tag/>)
345 On UNIX when POSIX threads are available, a separate library libyazthread
346 is created. Programmers should link with that library and the yaz library
347 when using threads. The reason for the split was that some applications
348 on Linux, such as Apache, doesn't work well when using shared objects that
351 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
352 (or any frontend server) in SSL mode by specifying ssl: followed by
353 address. Only tested on UNIX.
355 Added feature for CCL module. Virtual structure s=al or s=ol generates
356 and-list and or-list respectively instead of phrase search.
360 * Added prefix "yaz_" for the functions log_init.., log_file.. and
361 log_mask_str. This was done to avoid name conflicts with other libraries
362 (such as other PHP extensions).
364 Added raw OID member for preferred record syntax (request_format_raw)
365 and returned record syntax (output_format_raw) for backend fetch method.
367 Config file yaz-config now accepts options so that it returns specific
368 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
370 Shared library support for UNIX using GNU libtool.
372 * Modified backend interface. Request/Response struct's replaced by
373 one read/write C struct. For example bend_fetchrequest and
374 bend_fetchresult have been replaced by single bend_fetch_rr struct.
375 Every handler - even search has to be registered in bend_init
376 handler. This means that the YAZ library no longer refers to
377 external functions and it makes it possible to make the whole
378 thing a single DLL/SO.
380 Added Segment handler for backend server.
382 Added Zmbol/Zebra administrative functions to YAZ client.
384 Threaded frontend server on UNIX (when POSIX Threads are available).
385 Starting the server with option -T enables multi-threading.
389 Added configure option --enable-comp/disable-comp to control use
390 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
391 located in sub directory asn.
393 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
394 in ${exec_prefix}/bin along with the other programs yaz-client and
397 GNU automake used to maintain makefiles.
401 Changed retrieval module so that we can load records with no abstract
402 syntax defined. Tagpaths in these records are fully composed of string
405 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
409 On UNIX, the generated makefile now supports a proper 'make install'.
410 The prefix can be set via GNU configure to set the install location
411 (default is /usr/local).
413 * YAZ programs client and ztest were renamed to yaz-client and
414 yaz-ztest to avoid conflicts when users install YAZ in "standard"
415 locations, such as /usr/bin,/usr/local/bin,etc.
417 * YAZ Header files were moved from include to include/yaz. YAZ Header
418 files are referred to as include <yaz/log.h> rather than <log.h>.
419 The YAZ include path (-I ..) is therefore the same as before. Programmers
420 should update their #include statements or use -Ipath/include/yaz
421 instead. The main motivation for doing this change is that YAZ header files
422 can be installed in "standard" locations /usr/include,/usr/local/include
423 without introducing conflicts, since ALL YAZ header files are stored
424 in subdirectory yaz (under /usr/include for example).
426 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
427 rather than project/workspace files. We switched because project files
428 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
431 Changed name of logging function, logf, to yaz_log, to prevent name
432 clash with some math-log functions. The YAZ header log.h defines logf
433 to yaz_log (#define) so there should be no incompatibilities by this
436 Added bend_start/bend_stop handlers for server. These handler are
437 called on start/stop of server. For windows they are called whenever
438 a service is started/stopped.
440 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
441 a fairly small ASN.1 compiler written in Tcl. The compiler is located
442 in util/yc.tcl. The auto-generated C code structures are, in a few
443 cases, incompatible with the old decoders. There are differences in the
444 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
445 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
446 The preprocessor variable ASN_COMPILED is defined when the compiled
447 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
448 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
449 wish to use the old encoders/decoders you can specify --disable-yc
452 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
453 version so that it supports both new - and old version of DB Update
455 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
456 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
457 change. The name parameter can be set to 0 in which no name is specified
458 for the construction. The macros odr_implicit and odr_explicit sets name
459 parameter to zero for the construction involved. New macros
460 odr_implicit_tag and odr_explicit_tag are similar to the others,
461 except that a name parameter is added. For programmers' that don't use
462 ODR they probably only need to change the call to z_APDU and z_External.
464 Added access control facility by interfacing the TCP wrapper library.
465 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
466 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
467 name of the daemon and enables the access control as specified in
468 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
470 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
471 den Dool <H.M.vdnDool@kub.nl>.
473 Added reference ID parameter to most functions in server API - refer
474 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
476 Changed name of ccl library to libccl.a (was ccl.a).
478 Fixed bug in decoder for Explain (Category TargetInfo).
480 Added support for GNU readline in client. Thanks to Jacob Poulsen
481 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
483 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
484 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
485 IMPLEMENTATION! This change was made to the development version before
486 the ZIG decided to retract the amendment. If any users MUST be
487 compatible with the original Update definition, PLEASE CONTACT US, and
488 we will include a separate definition corresponding to the old Update
489 ES. Note that because of the change to the ASN.1 of the
490 TaskPackageRecordStructure we cannot define a single structure that
491 will support both versions.
493 * Added const modifier to buffer parameter for some ODR/BER encoding
494 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
495 completeWAIS, odr_dumpBER.
497 Fixed bug in client.c which caused a crash when a scanResponse didn't
498 contain positionOfTerm.
500 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
501 * will cause an error in a client if a non-YAZ target sends both a
502 * list of Scan entries and non-surrogate diagnostics.
504 Retrieval module enhancements. Tag sets may be typed in the reference
505 to it. From the .abs-file the "tagset" directive takes a third optional
506 integer type for the tag set referenced. From a .tag-file the "include"
507 directive takes a third optional type as well. The old "type" directive
508 in the tag set itself is still recognized but acts as the default type
511 Backend interface change. Individual Scan terms returned from bend_scan
512 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
513 in include/backend.h.
515 Retrieval module enhancements. Multiple tag sets and attribute sets may
516 be specified in abstract syntax specs. Revised the error/warning for
517 logging messages reported by the retrieval module when reading the
520 Object Identifier system (oid_..) changed. The API is backwards
521 compatible but the oid-routines now allocates new OID's when needed.
522 Raw OID's may be specified in oid_getvalbyname.
524 YAZ now uses GNU configure to generate Makefile(s).
526 * Minor changes in some of the member names of DeleteResultSetRequest and
527 DeleteResultSetResponse. See include/proto.h.
529 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
530 and added member 'languages' in TargetInfo (which was missing).
532 Changed the way attribute sets are handled in the retrieval
533 module. These are now cached, just like the abstract syntaxes
536 Changed YAZ so that it links with compiled ASN.1.
538 Added Explain-schema definitions and mapping routines. The following
539 Explain categories have been implemented: AttributeDetails,
540 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
542 Fixed minor bug in Windows version of Server Library.
544 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
546 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
548 Added EXTERNAL: UNIverse Resource Report (non-standard).
550 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
551 ENUMERATED and SET OF.
553 * Added 'const' to some of the char pointer arguments for the
554 functions, data1_read_node, data1_getelementbytagname,
555 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
558 Fixed bug in data1_insert_taggeddata - the last_child member of
559 parent wasn't initialised.
561 * Changed data1_read_record and data1_read_node so that the supplied
562 "SGML"-buffer is read-only. In particular the resulting data1 - tree
563 doesn't refer to any parts of the "SGML"-buffer.
565 Fixed bug in server library (Windows version of statserv_remove).
567 * Changed code so that it compiles as C++. The type definition
568 of Odr_fun which is a member of Odr_arm was changed. The result is,
569 that an explicit typecast is needed for the fun pointer when
570 using Odr_arm - as in:
571 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
573 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
575 Implemented the new structured date and time definition as approved
576 by the ZIG. Added schemaId element to the specificTag in Espec-1
577 (also approved at the last ZIG). Thanks to RVDM.
579 Added some Object identifiers (RVDM).
581 Changed the Update Extended Service (RVDM).
583 Added command "refid" to client which specifies referenceId for
584 the following requests.
586 Implemented extended service handling for server. See ztest.c
587 for an example as well as backend.h. New handlers are registerd
590 * Changed interface for sort in server.
592 Added new members to statserv_options_block. It allows a server
593 to read options from another source than just the command line. Thanks
594 to Charles Woodfield.
596 * Changed definition of Z_Triple in file prt-grs.h - member boolean
597 renamed to zboolean. Some C++ compilers complained about the name.
599 Minor changes to gils.abs. Added index 's' (sort) on title
600 and date/time-last-modified.
604 Fixed bug in server library regarding inetd mode (-i). This bug
605 was introduced by release 1.4.
609 Added sort facility in client and backend server interface.
611 Fixed problem with dependencies in Makefile(s).
613 Fixed bugs for encoders/decoders of extended services and
616 Implemented sub-tree feature for schemas. Sub-trees are
617 referenced in *.abs-files. See explain.abs for an example
618 of the use of this feature.
620 Modified bib1.att; local attributes for ANY didn't include
621 ANY itself (only affects use of the retrieval module).
623 Fixed bug in plain SGML reader in function data1_read_node:
624 tags with prefix "var" was incorrectly interpreted as variants.
626 Added feature "sub-schemas" to enable references to - and definitions
627 of - group of elements.
629 * Removed member parent from type data1_element (in data1.h).
631 Implemented function odr_nullval() that returns the value of
634 * Removed member num_children from data1_node (in data1.h).
636 Made NT service interface part of the server library. The
637 function statserv_main uses the NT service when required and
638 calls the statserv_start / statserv_close routines.
640 Routine zget_SearchRequest and zget_PresentRequest fills
641 resultSetName/Id member with "default" instead of "Default".
643 Fixed memory leak in server. Request queue member wasn't freed.
645 Fixed nmem_exit so that memory is freed.
649 Revised the CCL parser utility to be thread safe.
651 Added function, oid_ent_to_oid, to replace the function
652 oid_getoidbyent, which is not thread safe.
654 * Added nmem_init and nmem_exit to initialize and release
655 NMEM resources. Function nmem_init should be called once in the
656 initial thread before NMEM/ODR is used. statserv.c and client.c
657 have been changed accordingly. The change was necessary to make
658 NMEM thread safe. The NMEM memory pool is shared amongst threads
659 in a process. Unix-based applications will still work fine without
662 Added NT Services interface for the the Z39.50 (statserv) Server.
663 Refer to the ztest.c source on the usage.
665 Windows 95/NT port using MSVC5.0. Project files are included in the
668 * Defined new 'global' handle for the retrieval (data1) system. The
669 new handled, data1_handle, describes the state of the data1 system.
670 This handle is passed as first argument to virtually all
671 data1 related routines. The functions data1_create and data1_destroy
672 creates and destroys a data1 handle respectively.
674 Added ODR encode stream member to all backend request structures
675 init, search, scan etc. This stream should be used to allocate all
676 memory used for the response when thread safe operation is needed.
678 Changed the comstack utility, cs_addstr, to be thread safe. The
679 returned hostname string returned by the function is now part the
682 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
683 function. The cs_straddr takes a COMSTACK handle as argument, so this
684 function must be used after cs_create and before bind/connect.
685 This function is thread safe.
687 Moved test server to 'ztest' directory - generic server code still
688 in 'server' directory.
690 Made prefix query (pquery.c) utility thread safe.
692 Added new function modifier YAZ_EXPORT to 'export' public DLL
693 functions when using windows (see include/yconfig.h).
695 Added definitions to the OID database (util/oid.c) (RVDM).
697 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
699 Added call to ccl_rpn_delete in client program.
701 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
702 release of RPN structure.
704 Added support for C++, headers uses extern "C" for public definitions.
705 With input from RVDM.
707 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
708 Thanks to Ronald van der Meer (RVDM).
710 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
712 Added support for private extensions to the OID database
713 (oid_setprivateoids()). Thanks to RVDM.
715 Added optional, physical ANY (key replication)
717 Fixed null-reference problem in GRS-1 output filter.
719 Proximity operator added to Prefix Query Format (PQF).
721 In test client command "base" accepts multiple databases.
723 Fixed bug in cs_close stack that caused trouble with WINSOCK.
727 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
729 Smallish bug-fixes in the new encoders/decoders (explain).
731 Bug fixed in DeleteRequest.
733 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
735 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
737 Added SOIF syntax (using private OID for now) to retrieval module and client.
739 Added Update extended service.
741 Added SearchResult-1 additional info structure.
743 Added optional CCL (ISO8777) interpreter as separate module. Available
746 --- 1.2 1996/6/10 (1st anniversary release)
748 Added Summary record syntax. Lightly tested.
750 Added OPAC record syntax. Untested.
752 Added ResourceReport service encoders/decoders. Untested.
754 Fixed bug in z_Unit - wrong tagging on unitSystem.
756 Fixed bug in the DiagRecs decoder.
758 Added options for max PDU size and session timeout to frontend-server.
760 Added documentation of query-language parsers and other supporting utilities.
762 [frontend-server] Added Attribute set to the bend_scanrequest API.
764 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
765 surrogate diagnostics were generated.
767 [retrieval] Allow multiple local values for attribute.
769 [retrieval] Allow multiple attributes per element in .abs files. index type.
771 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
775 Minor changes, mostly specific to Zebra's requirements (retrieval)
779 Repaired bug in frontend server when running multiple listening
780 endpoints in dynamic mode.
782 z_External() now won't break if a known, ASN.1 value comes encapsulated
783 in an octet-string. The value will pass through unmodified in an Odr_oct.
785 Added a bit of code to the demo client to decode & display
786 ASN.1-structured records represented in the octet-aligned branch of
787 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
789 Added z_ext_getentbyref() to the ASN module. Doc updated.
791 * Completed the SCAN definition in the ASN module. This may break SCAN
792 code based on older YAZ-versions at compile-time. The fix is easy -
795 * Added 'displayTerm' and OtherInformation to the TermInfo structure
796 under the SCAN definition. Remember to initialize this, server-people.
798 Comstack should now support the WAIS protocol in TCP/IP mode. Note
799 that this does not extend to ODR and ASN.
801 Comstack allows insertion of established socket (primarily for
802 inetd-operation of servers). Doc updated.
804 Front-end server can now start from the inetd in TCP mode. Doc
811 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
812 the rank and record number.
814 Adjustments to the frontend server.
816 Fixed diagnostic BER dumper. It ignored the file argument.
820 Various changes to retrieval module.
822 Changed the union discriminators of the protocol files from enums to
823 ints paired with #defines.
825 *Changed oident.class to oident.oclass to avoid a reserved word in C++
828 *Changed operator in the RPN structure to 'roperator', again to avoid a
831 Fixed problems in Explain decoders/encoders.
835 Memory bug in log module fixed.
839 Occasional malloc() of 0 bytes fixed in d1_espec.c.
841 Bug in Explain DatabaseInfo module fixed.
843 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
847 The shift to v1.0 signals that we now consider the *core* functionality
848 of YAZ reasonably stable (the core being more or less equivalent to
849 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
850 tested (Explain not at all - though that will happen soonish).
852 Minor changes to code to support Windows port.
854 Various minor changes after we're getting to use GRS-1 & co. more.
856 Added Espec-1 format.
858 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
859 of the protocol and it cannot be selected when encoding (maps into 'string'
860 when decoding). Needed to talk to some servers.
862 Demo client can request simple element set names.
864 Added Diagnostic Format encoders/decoders.
866 Added simple Close handling to frontend server (no hooks for resource
867 reporting yet), and demonstration client.
869 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
873 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
874 handled incorrectly when records were requested in the searchResponse. This
875 will only affect you if you use the frontend-server.
877 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
878 Test-client will ask for and print GRS1. Ztest will return dummy records
881 Added Explain encoders/decoders to the service-level API. Untested.
883 Added Extended Services: Item Order encoders and decoders to the Service-
884 level API. Untested. We could use a recent copy of the pertinent bits
885 of the ILL protocol to add those bits.
887 Added diagnostic format 1 encoders/decoders to the service-level API.
890 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
891 odr_cons.c, which causes a more correct output.
893 Fixed handling of searchRequest in frontend server. NextResultSetPosition
894 was always set to 0 when no records were requested in the searchRequest.
896 * Added better external-handling. This shouldn't harm old code that
897 *encodes* externals. It can break code that looks for a
898 'single-ASN1-type' representation, since those types that are known
899 are now decoded immediately. Look at the SUTRS sample code in
900 seshigh.c and client.c. Documentation updated.
902 Handling of structured records in bend_fetchresponse. Length -1 marks
903 structured record, type is deduced from format field.
906 Fairly quick maintenance release to add SUTRS support.
908 Fixed handling of SUTRS records in the demonstration client.
910 * Added format field to the bend_fetchrequest and bend_fetchresponce
911 structures of the backend API (frontend server). When the record is
912 returned, the value of the format field is mapped to an OID. The
913 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
914 of the record. The special value VAL_NONE in the bend_request means
915 that no specific format was requested by the client. Documentation
916 updated accordingly. Test server (ztest) will return a fixed dummy
917 SUTRS record if your client requests SUTRS.
919 Documentation updated accordingly.
921 You can now set external libraries and RANLIB support in the top-level
925 First public release.
