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 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. + +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 +by the ZIG. Added schemaId element to the specificTag in Espec-1 +(also approved at the last ZIG). Thanks to RVDM. + +Added some Object identifiers (RVDM). + +Changed the Update Extended Service (RVDM). + +Added command "refid" to client which specifies referenceId for +the following requests. + +Implemented extended service handling for server. See ztest.c +for an example as well as backend.h. New handlers are registerd +in the Init handler. + +* Changed interface for sort in server. + +Added new members to statserv_options_block. It allows a server +to read options from another source than just the command line. Thanks +to Charles Woodfield. + +* Changed definition of Z_Triple in file prt-grs.h - member boolean +renamed to zboolean. Some C++ compilers complained about the name. + +Minor changes to gils.abs. Added index 's' (sort) on title +and date/time-last-modified. + +--- 1.4pl2 1998/1/30 + +Fixed bug in server library regarding inetd mode (-i). This bug +was introduced by release 1.4. + +--- 1.4pl1 1998/1/29 + +Added sort facility in client and backend server interface. + +Fixed problem with dependencies in Makefile(s). + +Fixed bugs for encoders/decoders of extended services and +SearchInfoReport. + +Implemented sub-tree feature for schemas. Sub-trees are +referenced in *.abs-files. See explain.abs for an example +of the use of this feature. + +Modified bib1.att; local attributes for ANY didn't include +ANY itself (only affects use of the retrieval module). + +Fixed bug in plain SGML reader in function data1_read_node: +tags with prefix "var" was incorrectly interpreted as variants. + +Added feature "sub-schemas" to enable references to - and definitions +of - group of elements. + +* Removed member parent from type data1_element (in data1.h). + +Implemented function odr_nullval() that returns the value of +ODR_NULLVAL. + +* Removed member num_children from data1_node (in data1.h). + +Made NT service interface part of the server library. The +function statserv_main uses the NT service when required and +calls the statserv_start / statserv_close routines. + +Routine zget_SearchRequest and zget_PresentRequest fills +resultSetName/Id member with "default" instead of "Default". + +Fixed memory leak in server. Request queue member wasn't freed. + +Fixed nmem_exit so that memory is freed. + +--- 1.4 1997/10/2 + +Revised the CCL parser utility to be thread safe. + +Added function, oid_ent_to_oid, to replace the function +oid_getoidbyent, which is not thread safe. + +* Added nmem_init and nmem_exit to initialize and release +NMEM resources. Function nmem_init should be called once in the +initial thread before NMEM/ODR is used. statserv.c and client.c +have been changed accordingly. The change was necessary to make +NMEM thread safe. The NMEM memory pool is shared amongst threads +in a process. Unix-based applications will still work fine without +calling this. + +Added NT Services interface for the the Z39.50 (statserv) Server. +Refer to the ztest.c source on the usage. + +Windows 95/NT port using MSVC5.0. Project files are included in the +distribution. + +* Defined new 'global' handle for the retrieval (data1) system. The +new handled, data1_handle, describes the state of the data1 system. +This handle is passed as first argument to virtually all +data1 related routines. The functions data1_create and data1_destroy +creates and destroys a data1 handle respectively. + +Added ODR encode stream member to all backend request structures +init, search, scan etc. This stream should be used to allocate all +memory used for the response when thread safe operation is needed. + +Changed the comstack utility, cs_addstr, to be thread safe. The +returned hostname string returned by the function is now part the +COMSTACK instance. + +Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr +function. The cs_straddr takes a COMSTACK handle as argument, so this +function must be used after cs_create and before bind/connect. +This function is thread safe. + +Moved test server to 'ztest' directory - generic server code still +in 'server' directory. + +Made prefix query (pquery.c) utility thread safe. + +Added new function modifier YAZ_EXPORT to 'export' public DLL +functions when using windows (see include/yconfig.h). + +Added definitions to the OID database (util/oid.c) (RVDM). + +Added new BIB-1 diagnostic messages to the handler diagbib1_str. + +Added call to ccl_rpn_delete in client program. + +Added ODR argument to ccl_rpn_query and ccl_scan_query to provide +release of RPN structure. + +Added support for C++, headers uses extern "C" for public definitions. +With input from RVDM. + +In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent. +Thanks to Ronald van der Meer (RVDM). + +Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM. + +Added support for private extensions to the OID database +(oid_setprivateoids()). Thanks to RVDM. + +Added optional, physical ANY (key replication) + +Fixed null-reference problem in GRS-1 output filter. + +Proximity operator added to Prefix Query Format (PQF). + +In test client command "base" accepts multiple databases. + +Fixed bug in cs_close stack that caused trouble with WINSOCK. + +--- 1.3 1996/10/11 Fixed tagging bug in ResourceReportResponse PDU encoder/decode. +Smallish bug-fixes in the new encoders/decoders (explain). + +Bug fixed in DeleteRequest. + +Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder. + +Fixed tagging bug in ResourceReportResponse PDU encoder/decode. + +Added SOIF syntax (using private OID for now) to retrieval module and client. + +Added Update extended service. + +Added SearchResult-1 additional info structure. + +Added optional CCL (ISO8777) interpreter as separate module. Available +in linemode client. + --- 1.2 1996/6/10 (1st anniversary release) Added Summary record syntax. Lightly tested.
