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. + +Added OPAC record syntax. Untested. + +Added ResourceReport service encoders/decoders. Untested. + +Fixed bug in z_Unit - wrong tagging on unitSystem. + +Fixed bug in the DiagRecs decoder. + +Added options for max PDU size and session timeout to frontend-server. + +Added documentation of query-language parsers and other supporting utilities. + +[frontend-server] Added Attribute set to the bend_scanrequest API. + +[frontend-server] NextResultSetPosition was sometimes set incorrectly when +surrogate diagnostics were generated. + +[retrieval] Allow multiple local values for attribute. + +[retrieval] Allow multiple attributes per element in .abs files. index type. + +[retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter. + +--- 1.1pl2 1996/4/10 + +Minor changes, mostly specific to Zebra's requirements (retrieval) + +--- 1.1 1996/2/20 + +Repaired bug in frontend server when running multiple listening +endpoints in dynamic mode. + +z_External() now won't break if a known, ASN.1 value comes encapsulated +in an octet-string. The value will pass through unmodified in an Odr_oct. + +Added a bit of code to the demo client to decode & display +ASN.1-structured records represented in the octet-aligned branch of +the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this. + +Added z_ext_getentbyref() to the ASN module. Doc updated. + +* Completed the SCAN definition in the ASN module. This may break SCAN +code based on older YAZ-versions at compile-time. The fix is easy - +look in proto.h. + +* Added 'displayTerm' and OtherInformation to the TermInfo structure +under the SCAN definition. Remember to initialize this, server-people. + +Comstack should now support the WAIS protocol in TCP/IP mode. Note +that this does not extend to ODR and ASN. + +Comstack allows insertion of established socket (primarily for +inetd-operation of servers). Doc updated. + +Front-end server can now start from the inetd in TCP mode. Doc +updated. + +--- 1.0pl4 1996/1/24 + +Added Sort PDU. + +Fixed small problem in SUTRS-filter. A newline was sometimes inserted before +the rank and record number. + +Adjustments to the frontend server. + +Fixed diagnostic BER dumper. It ignored the file argument. + +--- 1.0pl3 1996/1/2 + +Various changes to retrieval module. + +Changed the union discriminators of the protocol files from enums to +ints paired with #defines. + +*Changed oident.class to oident.oclass to avoid a reserved word in C++ + compilers. + +*Changed operator in the RPN structure to 'roperator', again to avoid a + conflict with C++. + +Fixed problems in Explain decoders/encoders. + +--- 1.0pl2 1995/12/6 + +Memory bug in log module fixed. + +--- 1.0pl1 1995/12/5 + +Occasional malloc() of 0 bytes fixed in d1_espec.c. + +Bug in Explain DatabaseInfo module fixed. + +Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows. + +--- 1.0 1995/11/28 + +The shift to v1.0 signals that we now consider the *core* functionality +of YAZ reasonably stable (the core being more or less equivalent to +Z39.50-1992). Some of the really nifty v3 stuff is still not heavily +tested (Explain not at all - though that will happen soonish). + +Minor changes to code to support Windows port. + +Various minor changes after we're getting to use GRS-1 & co. more.
