1 Possible compatibility problems with earlier versions marked with '*'.
5 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
8 Configure option --with-openssl=<dir> now works when a directory is
9 specified. Patch provided by Morten Bøgeskov.
11 New option for YAZ client, -u <auth>, that sets authentication.
13 ZOOM fix: error information only cleared for Bib-diagnostics (not
14 fatal errors, like connection failed, etc).
16 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
20 Scan for ZOOM API. New object ZOOM_scanset. New functions
21 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
24 New ZOOM function, ZOOM_connection_last_event, that returns type
25 of last event (such as "receive data", "send data", "apdu received",
28 New ZOOM option, schema, that specifies shema OID for retrieval.
30 New CCL feature. Qualifiers can be aliases for one or more
31 other qualifiers (if more than one is given, OR is used).
33 ZOOM uses named result sets if target supports it.
35 Two new YAZ client commands: . (dot, which sources a script of YAZ
36 client commands), and ! (to execute shell command.). Implemented
39 Working on Debian packages.
43 YAZ client enables named result sets only if target supports it.
45 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
47 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
48 with key="host" to get same result.
50 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
51 Function Z3950_resultset_record(s) returns references to records
52 "owned" by resultset. To become owner use Z3950_record_clone.
54 Function z_ext_record handles Extended Services. Thanks to
59 CCL Parser fix: ignore token comma when dealing with and-lists.
61 Documentation updates for COMSTACK.
63 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
64 Changed prototype Z3950_records. For some functions, int parameters
65 were changed to size_t.
67 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
70 New MARC decode/display function, marc_display_exl, which properly rejects
71 non-ISO2709 records. YAZ client uses it.
75 Fix bug: local attribute set wasn't set correctly in PQF strings.
79 * Old Z39.50 codecs no longer supported.
81 Added ZOOM C binding. See http://zoom.z3950.org/
83 Renamed states for COMSTACKs to avoid confusion with events.
85 Implemented cs_look and proper cs_rcvconnect.
87 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
89 Configure detects POSIX threads on OpenBSD.
91 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
92 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
94 When error is returned from present handler, non-surrogate diagnostic
95 is returned in present response (and fetch handler is no longer called).
97 * Minor adjustments to pquery parser (PQF). Token characters may be
98 escaped by using backslash (C-style).
100 PQF parser allows string attribute values to be specified. For @attr,
101 non-numeric characters after the equal-sign are treated as strings
102 (e.g. @attr 9=title).
104 CCL trunction character may be defined (@truncation in file)
106 * function zget_ExtendedServicesRequest sets waitAction to
107 waitIfPossible (was wait).
109 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
112 CCL operator names may be set in field definition files (CCL_bibset).
113 See ccl/bib1 for an example.
115 Fixes in ASN.1 compiler for C++ compatibility.
117 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
118 and "op_or" to avoid conflict with C++.
120 Fixed problem with GNU readline detection on Redhat 7.0.
122 Added step-size for Scan backend handler.
124 Fixed bug that made the frontend server crash when no attribute
125 set was specified for scan.
127 Front-end server automatically switches to original working directory
128 when installed as an NT service. Previously -w had to be specified to
131 Added extended attributes for retrieval module (data1), so that data1
132 records carry d1_readXML/SGML attributes. d1_read also supports
133 null-data rules ( <tag/>)
135 On UNIX when POSIX threads are available, a separate library libyazthread
136 is created. Programmers should link with that library and the yaz library
137 when using threads. The reason for the split was that some applications
138 on Linux, such as Apache, doesn't work well when using shared objects that
141 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
142 (or any frontend server) in SSL mode by specifying ssl: followed by
143 address. Only tested on UNIX.
145 Added feature for CCL module. Virtual structure s=al or s=ol generates
146 and-list and or-list respectively instead of phrase search.
150 * Added prefix "yaz_" for the functions log_init.., log_file.. and
151 log_mask_str. This was done to avoid name conflicts with other libraries
152 (such as other PHP extensions).
154 Added raw OID member for preferred record syntax (request_format_raw)
155 and returned record syntax (output_format_raw) for backend fetch method.
157 Config file yaz-config now accepts options so that it returns specific
158 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
160 Shared library support for UNIX using GNU libtool.
162 * Modified backend interface. Request/Response struct's replaced by
163 one read/write C struct. For example bend_fetchrequest and
164 bend_fetchresult have been replaced by single bend_fetch_rr struct.
165 Every handler - even search has to be registered in bend_init
166 handler. This means that the YAZ library no longer refers to
167 external functions and it makes it possible to make the whole
168 thing a single DLL/SO.
170 Added Segment handler for backend server.
172 Added Zmbol/Zebra administrative functions to YAZ client.
174 Threaded frontend server on UNIX (when POSIX Threads are available).
175 Starting the server with option -T enables multi-threading.
179 Added configure option --enable-comp/disable-comp to control use
180 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
181 located in sub directory asn.
183 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
184 in ${exec_prefix}/bin along with the other programs yaz-client and
187 GNU automake used to maintain makefiles.
191 Changed retrieval module so that we can load records with no abstract
192 syntax defined. Tagpaths in these records are fully composed of string
195 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
199 On UNIX, the generated makefile now supports a proper 'make install'.
200 The prefix can be set via GNU configure to set the install location
201 (default is /usr/local).
203 * YAZ programs client and ztest were renamed to yaz-client and
204 yaz-ztest to avoid conflicts when users install YAZ in "standard"
205 locations, such as /usr/bin,/usr/local/bin,etc.
207 * YAZ Header files were moved from include to include/yaz. YAZ Header
208 files are referred to as include <yaz/log.h> rather than <log.h>.
209 The YAZ include path (-I ..) is therefore the same as before. Programmers
210 should update their #include statements or use -Ipath/include/yaz
211 instead. The main motivation for doing this change is that YAZ header files
212 can be installed in "standard" locations /usr/include,/usr/local/include
213 without introducing conflicts, since ALL YAZ header files are stored
214 in subdirectory yaz (under /usr/include for example).
216 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
217 rather than project/workspace files. We switched because project files
218 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
221 Changed name of logging function, logf, to yaz_log, to prevent name
222 clash with some math-log functions. The YAZ header log.h defines logf
223 to yaz_log (#define) so there should be no incompatibilities by this
226 Added bend_start/bend_stop handlers for server. These handler are
227 called on start/stop of server. For windows they are called whenever
228 a service is started/stopped.
230 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
231 a fairly small ASN.1 compiler written in Tcl. The compiler is located
232 in util/yc.tcl. The auto-generated C code structures are, in a few
233 cases, incompatible with the old decoders. There are differences in the
234 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
235 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
236 The preprocessor variable ASN_COMPILED is defined when the compiled
237 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
238 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
239 wish to use the old encoders/decoders you can specify --disable-yc
242 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
243 version so that it supports both new - and old version of DB Update
245 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
246 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
247 change. The name parameter can be set to 0 in which no name is specified
248 for the construction. The macros odr_implicit and odr_explicit sets name
249 parameter to zero for the construction involved. New macros
250 odr_implicit_tag and odr_explicit_tag are similar to the others,
251 except that a name parameter is added. For programmers' that don't use
252 ODR they probably only need to change the call to z_APDU and z_External.
254 Added access control facility by interfacing the TCP wrapper library.
255 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
256 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
257 name of the daemon and enables the access control as specified in
258 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
260 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
261 den Dool <H.M.vdnDool@kub.nl>.
263 Added reference ID parameter to most functions in server API - refer
264 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
266 Changed name of ccl library to libccl.a (was ccl.a).
268 Fixed bug in decoder for Explain (Category TargetInfo).
270 Added support for GNU readline in client. Thanks to Jacob Poulsen
271 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
273 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
274 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
275 IMPLEMENTATION! This change was made to the development version before
276 the ZIG decided to retract the amendment. If any users MUST be
277 compatible with the original Update definition, PLEASE CONTACT US, and
278 we will include a separate definition corresponding to the old Update
279 ES. Note that because of the change to the ASN.1 of the
280 TaskPackageRecordStructure we cannot define a single structure that
281 will support both versions.
283 * Added const modifier to buffer parameter for some ODR/BER encoding
284 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
285 completeWAIS, odr_dumpBER.
287 Fixed bug in client.c which caused a crash when a scanResponse didn't
288 contain positionOfTerm.
290 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
291 * will cause an error in a client if a non-YAZ target sends both a
292 * list of Scan entries and non-surrogate diagnostics.
294 Retrieval module enhancements. Tag sets may be typed in the reference
295 to it. From the .abs-file the "tagset" directive takes a third optional
296 integer type for the tag set referenced. From a .tag-file the "include"
297 directive takes a third optional type as well. The old "type" directive
298 in the tag set itself is still recognized but acts as the default type
301 Backend interface change. Individual Scan terms returned from bend_scan
302 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
303 in include/backend.h.
305 Retrieval module enhancements. Multiple tag sets and attribute sets may
306 be specified in abstract syntax specs. Revised the error/warning for
307 logging messages reported by the retrieval module when reading the
310 Object Identifier system (oid_..) changed. The API is backwards
311 compatible but the oid-routines now allocates new OID's when needed.
312 Raw OID's may be specified in oid_getvalbyname.
314 YAZ now uses GNU configure to generate Makefile(s).
316 * Minor changes in some of the member names of DeleteResultSetRequest and
317 DeleteResultSetResponse. See include/proto.h.
319 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
320 and added member 'languages' in TargetInfo (which was missing).
322 Changed the way attribute sets are handled in the retrieval
323 module. These are now cached, just like the abstract syntaxes
326 Changed YAZ so that it links with compiled ASN.1.
328 Added Explain-schema definitions and mapping routines. The following
329 Explain categories have been implemented: AttributeDetails,
330 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
332 Fixed minor bug in Windows version of Server Library.
334 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
336 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
338 Added EXTERNAL: UNIverse Resource Report (non-standard).
340 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
341 ENUMERATED and SET OF.
343 * Added 'const' to some of the char pointer arguments for the
344 functions, data1_read_node, data1_getelementbytagname,
345 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
348 Fixed bug in data1_insert_taggeddata - the last_child member of
349 parent wasn't initialised.
351 * Changed data1_read_record and data1_read_node so that the supplied
352 "SGML"-buffer is read-only. In particular the resulting data1 - tree
353 doesn't refer to any parts of the "SGML"-buffer.
355 Fixed bug in server library (Windows version of statserv_remove).
357 * Changed code so that it compiles as C++. The type definition
358 of Odr_fun which is a member of Odr_arm was changed. The result is,
359 that an explicit typecast is needed for the fun pointer when
360 using Odr_arm - as in:
361 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
363 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
365 Implemented the new structured date and time definition as approved
366 by the ZIG. Added schemaId element to the specificTag in Espec-1
367 (also approved at the last ZIG). Thanks to RVDM.
369 Added some Object identifiers (RVDM).
371 Changed the Update Extended Service (RVDM).
373 Added command "refid" to client which specifies referenceId for
374 the following requests.
376 Implemented extended service handling for server. See ztest.c
377 for an example as well as backend.h. New handlers are registerd
380 * Changed interface for sort in server.
382 Added new members to statserv_options_block. It allows a server
383 to read options from another source than just the command line. Thanks
384 to Charles Woodfield.
386 * Changed definition of Z_Triple in file prt-grs.h - member boolean
387 renamed to zboolean. Some C++ compilers complained about the name.
389 Minor changes to gils.abs. Added index 's' (sort) on title
390 and date/time-last-modified.
394 Fixed bug in server library regarding inetd mode (-i). This bug
395 was introduced by release 1.4.
399 Added sort facility in client and backend server interface.
401 Fixed problem with dependencies in Makefile(s).
403 Fixed bugs for encoders/decoders of extended services and
406 Implemented sub-tree feature for schemas. Sub-trees are
407 referenced in *.abs-files. See explain.abs for an example
408 of the use of this feature.
410 Modified bib1.att; local attributes for ANY didn't include
411 ANY itself (only affects use of the retrieval module).
413 Fixed bug in plain SGML reader in function data1_read_node:
414 tags with prefix "var" was incorrectly interpreted as variants.
416 Added feature "sub-schemas" to enable references to - and definitions
417 of - group of elements.
419 * Removed member parent from type data1_element (in data1.h).
421 Implemented function odr_nullval() that returns the value of
424 * Removed member num_children from data1_node (in data1.h).
426 Made NT service interface part of the server library. The
427 function statserv_main uses the NT service when required and
428 calls the statserv_start / statserv_close routines.
430 Routine zget_SearchRequest and zget_PresentRequest fills
431 resultSetName/Id member with "default" instead of "Default".
433 Fixed memory leak in server. Request queue member wasn't freed.
435 Fixed nmem_exit so that memory is freed.
439 Revised the CCL parser utility to be thread safe.
441 Added function, oid_ent_to_oid, to replace the function
442 oid_getoidbyent, which is not thread safe.
444 * Added nmem_init and nmem_exit to initialize and release
445 NMEM resources. Function nmem_init should be called once in the
446 initial thread before NMEM/ODR is used. statserv.c and client.c
447 have been changed accordingly. The change was necessary to make
448 NMEM thread safe. The NMEM memory pool is shared amongst threads
449 in a process. Unix-based applications will still work fine without
452 Added NT Services interface for the the Z39.50 (statserv) Server.
453 Refer to the ztest.c source on the usage.
455 Windows 95/NT port using MSVC5.0. Project files are included in the
458 * Defined new 'global' handle for the retrieval (data1) system. The
459 new handled, data1_handle, describes the state of the data1 system.
460 This handle is passed as first argument to virtually all
461 data1 related routines. The functions data1_create and data1_destroy
462 creates and destroys a data1 handle respectively.
464 Added ODR encode stream member to all backend request structures
465 init, search, scan etc. This stream should be used to allocate all
466 memory used for the response when thread safe operation is needed.
468 Changed the comstack utility, cs_addstr, to be thread safe. The
469 returned hostname string returned by the function is now part the
472 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
473 function. The cs_straddr takes a COMSTACK handle as argument, so this
474 function must be used after cs_create and before bind/connect.
475 This function is thread safe.
477 Moved test server to 'ztest' directory - generic server code still
478 in 'server' directory.
480 Made prefix query (pquery.c) utility thread safe.
482 Added new function modifier YAZ_EXPORT to 'export' public DLL
483 functions when using windows (see include/yconfig.h).
485 Added definitions to the OID database (util/oid.c) (RVDM).
487 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
489 Added call to ccl_rpn_delete in client program.
491 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
492 release of RPN structure.
494 Added support for C++, headers uses extern "C" for public definitions.
495 With input from RVDM.
497 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
498 Thanks to Ronald van der Meer (RVDM).
500 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
502 Added support for private extensions to the OID database
503 (oid_setprivateoids()). Thanks to RVDM.
505 Added optional, physical ANY (key replication)
507 Fixed null-reference problem in GRS-1 output filter.
509 Proximity operator added to Prefix Query Format (PQF).
511 In test client command "base" accepts multiple databases.
513 Fixed bug in cs_close stack that caused trouble with WINSOCK.
517 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
519 Smallish bug-fixes in the new encoders/decoders (explain).
521 Bug fixed in DeleteRequest.
523 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
525 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
527 Added SOIF syntax (using private OID for now) to retrieval module and client.
529 Added Update extended service.
531 Added SearchResult-1 additional info structure.
533 Added optional CCL (ISO8777) interpreter as separate module. Available
536 --- 1.2 1996/6/10 (1st anniversary release)
538 Added Summary record syntax. Lightly tested.
540 Added OPAC record syntax. Untested.
542 Added ResourceReport service encoders/decoders. Untested.
544 Fixed bug in z_Unit - wrong tagging on unitSystem.
546 Fixed bug in the DiagRecs decoder.
548 Added options for max PDU size and session timeout to frontend-server.
550 Added documentation of query-language parsers and other supporting utilities.
552 [frontend-server] Added Attribute set to the bend_scanrequest API.
554 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
555 surrogate diagnostics were generated.
557 [retrieval] Allow multiple local values for attribute.
559 [retrieval] Allow multiple attributes per element in .abs files. index type.
561 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
565 Minor changes, mostly specific to Zebra's requirements (retrieval)
569 Repaired bug in frontend server when running multiple listening
570 endpoints in dynamic mode.
572 z_External() now won't break if a known, ASN.1 value comes encapsulated
573 in an octet-string. The value will pass through unmodified in an Odr_oct.
575 Added a bit of code to the demo client to decode & display
576 ASN.1-structured records represented in the octet-aligned branch of
577 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
579 Added z_ext_getentbyref() to the ASN module. Doc updated.
581 * Completed the SCAN definition in the ASN module. This may break SCAN
582 code based on older YAZ-versions at compile-time. The fix is easy -
585 * Added 'displayTerm' and OtherInformation to the TermInfo structure
586 under the SCAN definition. Remember to initialize this, server-people.
588 Comstack should now support the WAIS protocol in TCP/IP mode. Note
589 that this does not extend to ODR and ASN.
591 Comstack allows insertion of established socket (primarily for
592 inetd-operation of servers). Doc updated.
594 Front-end server can now start from the inetd in TCP mode. Doc
601 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
602 the rank and record number.
604 Adjustments to the frontend server.
606 Fixed diagnostic BER dumper. It ignored the file argument.
610 Various changes to retrieval module.
612 Changed the union discriminators of the protocol files from enums to
613 ints paired with #defines.
615 *Changed oident.class to oident.oclass to avoid a reserved word in C++
618 *Changed operator in the RPN structure to 'roperator', again to avoid a
621 Fixed problems in Explain decoders/encoders.
625 Memory bug in log module fixed.
629 Occasional malloc() of 0 bytes fixed in d1_espec.c.
631 Bug in Explain DatabaseInfo module fixed.
633 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
637 The shift to v1.0 signals that we now consider the *core* functionality
638 of YAZ reasonably stable (the core being more or less equivalent to
639 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
640 tested (Explain not at all - though that will happen soonish).
642 Minor changes to code to support Windows port.
644 Various minor changes after we're getting to use GRS-1 & co. more.
646 Added Espec-1 format.
648 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
649 of the protocol and it cannot be selected when encoding (maps into 'string'
650 when decoding). Needed to talk to some servers.
652 Demo client can request simple element set names.
654 Added Diagnostic Format encoders/decoders.
656 Added simple Close handling to frontend server (no hooks for resource
657 reporting yet), and demonstration client.
659 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
663 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
664 handled incorrectly when records were requested in the searchResponse. This
665 will only affect you if you use the frontend-server.
667 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
668 Test-client will ask for and print GRS1. Ztest will return dummy records
671 Added Explain encoders/decoders to the service-level API. Untested.
673 Added Extended Services: Item Order encoders and decoders to the Service-
674 level API. Untested. We could use a recent copy of the pertinent bits
675 of the ILL protocol to add those bits.
677 Added diagnostic format 1 encoders/decoders to the service-level API.
680 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
681 odr_cons.c, which causes a more correct output.
683 Fixed handling of searchRequest in frontend server. NextResultSetPosition
684 was always set to 0 when no records were requested in the searchRequest.
686 * Added better external-handling. This shouldn't harm old code that
687 *encodes* externals. It can break code that looks for a
688 'single-ASN1-type' representation, since those types that are known
689 are now decoded immediately. Look at the SUTRS sample code in
690 seshigh.c and client.c. Documentation updated.
692 Handling of structured records in bend_fetchresponse. Length -1 marks
693 structured record, type is deduced from format field.
696 Fairly quick maintenance release to add SUTRS support.
698 Fixed handling of SUTRS records in the demonstration client.
700 * Added format field to the bend_fetchrequest and bend_fetchresponce
701 structures of the backend API (frontend server). When the record is
702 returned, the value of the format field is mapped to an OID. The
703 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
704 of the record. The special value VAL_NONE in the bend_request means
