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. -Possible compatibility problems with earlier versions marked with '*'. - -Routine zget_SearchRequest fills resultSetName member with "default" -instead of "Default". +Routine zget_SearchRequest and zget_PresentRequest fills +resultSetName/Id member with "default" instead of "Default".
