Possible compatibility problems with earlier versions marked with '*'. --- Added documentation of query-language parsers and other utilities. Added Attribute set to the bend_scanrequest API. [retrieval] Allow multiple local values for attribute. [retrieval} Allow multiple attributes per element in .abs files. index type. --- 1.1pl2 1996/4/10 Minor changes, mostly specific to Zebra --- 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. Added Espec-1 format. Added VisibleString field body type to GRS-1. It is illegal acc. to my copy of the protocol and it cannot be selected when encoding (maps into 'string' when decoding). Needed to talk to some servers. Demo client can request simple element set names. Added Diagnostic Format encoders/decoders. Added simple Close handling to frontend server (no hooks for resource reporting yet), and demonstration client. Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address. --- 1.0b3 1995/08/24 Fixed bug in the frontend-server. The numberOfRecordsReturned field was handled incorrectly when records were requested in the searchResponse. This will only affect you if you use the frontend-server. Added GRS-1 encoders/decoders to the service-level API. Lightly tested. Test-client will ask for and print GRS1. Ztest will return dummy records on request. Added Explain encoders/decoders to the service-level API. Untested. Added Extended Services: Item Order encoders and decoders to the Service- level API. Untested. We could use a recent copy of the pertinent bits of the ILL protocol to add those bits. Added diagnostic format 1 encoders/decoders to the service-level API. Untested. Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to odr_cons.c, which causes a more correct output. Fixed handling of searchRequest in frontend server. NextResultSetPosition was always set to 0 when no records were requested in the searchRequest. * Added better external-handling. This shouldn't harm old code that *encodes* externals. It can break code that looks for a 'single-ASN1-type' representation, since those types that are known are now decoded immediately. Look at the SUTRS sample code in seshigh.c and client.c. Documentation updated. Handling of structured records in bend_fetchresponse. Length -1 marks structured record, type is deduced from format field. --- 1.0b2 1995/06/27 Fairly quick maintenance release to add SUTRS support. Fixed handling of SUTRS records in the demonstration client. * Added format field to the bend_fetchrequest and bend_fetchresponce structures of the backend API (frontend server). When the record is returned, the value of the format field is mapped to an OID. The value VAL_SUTRS will also cause a slightly different ASN.1 packaging of the record. The special value VAL_NONE in the bend_request means that no specific format was requested by the client. Documentation updated accordingly. Test server (ztest) will return a fixed dummy SUTRS record if your client requests SUTRS. Documentation updated accordingly. You can now set external libraries and RANLIB support in the top-level Makefile. --- 1.0b 1995/06/19 First public release.
