Thanks +to Matthew Carey. + +CCL operator names may be set in field definition files (CCL_bibset). +See ccl/bib1 for an example. + +Fixes in ASN.1 compiler for C++ compatibility. + +* Renamed members "and" and "or" in struct Z_Operator to "op_and" +and "op_or" to avoid conflict with C++. + +Fixed problem with GNU readline detection on Redhat 7.0. + +Added step-size for Scan backend handler. + +Fixed bug that made the frontend server crash when no attribute +set was specified for scan. + +Front-end server automatically switches to original working directory +when installed as an NT service. Previously -w had to be specified to +make it work. + +Added extended attributes for retrieval module (data1), so that data1 +records carry d1_readXML/SGML attributes. d1_read also supports +null-data rules ( ) + +On UNIX when POSIX threads are available, a separate library libyazthread +is created. Programmers should link with that library and the yaz library +when using threads. The reason for the split was that some applications +on Linux, such as Apache, doesn't work well when using shared objects that +relies on threads. + +Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest +(or any frontend server) in SSL mode by specifying ssl: followed by +address. Only tested on UNIX. + +Added feature for CCL module. Virtual structure s=al or s=ol generates +and-list and or-list respectively instead of phrase search. + +Added some OID's. + +* Added prefix "yaz_" for the functions log_init.., log_file.. and +log_mask_str. This was done to avoid name conflicts with other libraries +(such as other PHP extensions). + +Added raw OID member for preferred record syntax (request_format_raw) +and returned record syntax (output_format_raw) for backend fetch method. + +Config file yaz-config now accepts options so that it returns specific +compile settings, etc. Thanks to Morten Bøgeskov + +Shared library support for UNIX using GNU libtool. + +* Modified backend interface. Request/Response struct's replaced by +one read/write C struct. For example bend_fetchrequest and +bend_fetchresult have been replaced by single bend_fetch_rr struct. +Every handler - even search has to be registered in bend_init +handler. This means that the YAZ library no longer refers to +external functions and it makes it possible to make the whole +thing a single DLL/SO. + +Added Segment handler for backend server. + +Added Zmbol/Zebra administrative functions to YAZ client. + +Threaded frontend server on UNIX (when POSIX Threads are available). +Starting the server with option -T enables multi-threading. + +--- 1.6 2000/03/03 + +Added configure option --enable-comp/disable-comp to control use +of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders +located in sub directory asn. + +YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed +in ${exec_prefix}/bin along with the other programs yaz-client and +yaz-ztest. + +GNU automake used to maintain makefiles. + +Added several OID's. + +Changed retrieval module so that we can load records with no abstract +syntax defined. Tagpaths in these records are fully composed of string +tags. + +Implemented ISO ILL protocol. Refer to stuff in sub directory ill. + +--- 1.5 1999/12/10 + +On UNIX, the generated makefile now supports a proper 'make install'. +The prefix can be set via GNU configure to set the install location +(default is /usr/local). + +* YAZ programs client and ztest were renamed to yaz-client and +yaz-ztest to avoid conflicts when users install YAZ in "standard" +locations, such as /usr/bin,/usr/local/bin,etc. + +* YAZ Header files were moved from include to include/yaz. YAZ Header +files are referred to as include rather than . +The YAZ include path (-I ..) is therefore the same as before. Programmers +should update their #include statements or use -Ipath/include/yaz +instead. The main motivation for doing this change is that YAZ header files +can be installed in "standard" locations /usr/include,/usr/local/include +without introducing conflicts, since ALL YAZ header files are stored +in subdirectory yaz (under /usr/include for example). + +Compilation of YAZ for WIN32 is now handled by an nmake-style makefile +rather than project/workspace files. We switched because project files +are incompatible between Visual C++ 5 and 6. Refer to windows.txt for +details. + +Changed name of logging function, logf, to yaz_log, to prevent name +clash with some math-log functions. The YAZ header log.h defines logf +to yaz_log (#define) so there should be no incompatibilities by this +modification. + +Added bend_start/bend_stop handlers for server. These handler are +called on start/stop of server. For windows they are called whenever +a service is started/stopped. + +* YAZ now auto-generates decoders/encoders for the Z39.50 protocol using +a fairly small ASN.1 compiler written in Tcl. The compiler is located +in util/yc.tcl. The auto-generated C code structures are, in a few +cases, incompatible with the old decoders. There are differences in the +following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse, +Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat. +The preprocessor variable ASN_COMPILED is defined when the compiled +ASN.1 is being used. Encoder/decoder routines as well as the Z39.50 +protocol ASN.1 is located sub directory z39.50. If you +wish to use the old encoders/decoders you can specify --disable-yc +for configure. + +Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled +version so that it supports both new - and old version of DB Update + +* Added 'name' parameter to ODR encoder/decoder routines to facilitate +pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the +change. The name parameter can be set to 0 in which no name is specified +for the construction. The macros odr_implicit and odr_explicit sets name +parameter to zero for the construction involved. New macros +odr_implicit_tag and odr_explicit_tag are similar to the others, +except that a name parameter is added. For programmers' that don't use +ODR they probably only need to change the call to z_APDU and z_External. + +Added access control facility by interfacing the TCP wrapper library. +YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and +tcpd.h on Unix systems. For the server, option -d specifies the +name of the daemon and enables the access control as specified in +hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5). + +Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van +den Dool . + +Added reference ID parameter to most functions in server API - refer +to backend.h. Thanks to Hans van den Dool . + +Changed name of ccl library to libccl.a (was ccl.a). + +Fixed bug in decoder for Explain (Category TargetInfo). + +Added support for GNU readline in client. Thanks to Jacob Poulsen +. GNU configure attempts to detect if readline is available. + +* CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the +new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE +IMPLEMENTATION! This change was made to the development version before +the ZIG decided to retract the amendment. If any users MUST be +compatible with the original Update definition, PLEASE CONTACT US, and +we will include a separate definition corresponding to the old Update +ES. Note that because of the change to the ASN.1 of the +TaskPackageRecordStructure we cannot define a single structure that +will support both versions. + +* Added const modifier to buffer parameter for some ODR/BER encoding +routines: ber_dectag, ber_declen, odp_more_chunks, completeBER, +completeWAIS, odr_dumpBER. + +Fixed bug in client.c which caused a crash when a scanResponse didn't +contain positionOfTerm. + +* Fixed inconsistency in the ScanResponse/ListEntries protocol. This +* will cause an error in a client if a non-YAZ target sends both a +* list of Scan entries and non-surrogate diagnostics. + +Retrieval module enhancements. Tag sets may be typed in the reference +to it. From the .abs-file the "tagset" directive takes a third optional +integer type for the tag set referenced. From a .tag-file the "include" +directive takes a third optional type as well. The old "type" directive +in the tag set itself is still recognized but acts as the default type +for the tag set. + +Backend interface change. Individual Scan terms returned from bend_scan +may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry +in include/backend.h. + +Retrieval module enhancements. Multiple tag sets and attribute sets may +be specified in abstract syntax specs. Revised the error/warning for +logging messages reported by the retrieval module when reading the +various spec files. + +Object Identifier system (oid_..) changed. The API is backwards +compatible but the oid-routines now allocates new OID's when needed. +Raw OID's may be specified in oid_getvalbyname. + +YAZ now uses GNU configure to generate Makefile(s). + +* Minor changes in some of the member names of DeleteResultSetRequest and +DeleteResultSetResponse. See include/proto.h. + +* Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h) +and added member 'languages' in TargetInfo (which was missing). + +Changed the way attribute sets are handled in the retrieval +module. These are now cached, just like the abstract syntaxes +(schemas). + +Changed YAZ so that it links with compiled ASN.1. + +Added Explain-schema definitions and mapping routines. The following +Explain categories have been implemented: AttributeDetails, +AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo. + +Fixed minor bug in Windows version of Server Library. + +--- 1.4pl2+ 1998/4/17 (Released with Zebra) + +Added Extended Services to server (backend.h). Thanks to Charles Woodfield. + +Added EXTERNAL: UNIverse Resource Report (non-standard). + +Implemened odr_enum and odr_set_of functions to handle ASN.1 types +ENUMERATED and SET OF. + +* Added 'const' to some of the char pointer arguments for the +functions, data1_read_node, data1_getelementbytagname, +data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname, +data1_get_absyn. + +Fixed bug in data1_insert_taggeddata - the last_child member of +parent wasn't initialised. + +* Changed data1_read_record and data1_read_node so that the supplied +"SGML"-buffer is read-only. In particular the resulting data1 - tree +doesn't refer to any parts of the "SGML"-buffer. + +Fixed bug in server library (Windows version of statserv_remove). + +* Changed code so that it compiles as C++. The type definition +of Odr_fun which is a member of Odr_arm was changed. The result is, +that an explicit typecast is needed for the fun pointer when +using Odr_arm - as in: + {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass}, + Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag). Implemented the new structured date and time definition as approved
