1 Possible compatibility problems with earlier versions marked with '*'.
5 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
7 Added SOIF syntax (using private OID for now) to retrieval module and client.
9 --- 1.2 1996/6/10 (1st anniversary release)
11 Added Summary record syntax. Lightly tested.
13 Added OPAC record syntax. Untested.
15 Added ResourceReport service encoders/decoders. Untested.
17 Fixed bug in z_Unit - wrong tagging on unitSystem.
19 Fixed bug in the DiagRecs decoder.
21 Added options for max PDU size and session timeout to frontend-server.
23 Added documentation of query-language parsers and other supporting utilities.
25 [frontend-server] Added Attribute set to the bend_scanrequest API.
27 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
28 surrogate diagnostics were generated.
30 [retrieval] Allow multiple local values for attribute.
32 [retrieval] Allow multiple attributes per element in .abs files. index type.
34 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
38 Minor changes, mostly specific to Zebra's requirements (retrieval)
42 Repaired bug in frontend server when running multiple listening
43 endpoints in dynamic mode.
45 z_External() now won't break if a known, ASN.1 value comes encapsulated
46 in an octet-string. The value will pass through unmodified in an Odr_oct.
48 Added a bit of code to the demo client to decode & display
49 ASN.1-structured records represented in the octet-aligned branch of
50 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
52 Added z_ext_getentbyref() to the ASN module. Doc updated.
54 * Completed the SCAN definition in the ASN module. This may break SCAN
55 code based on older YAZ-versions at compile-time. The fix is easy -
58 * Added 'displayTerm' and OtherInformation to the TermInfo structure
59 under the SCAN definition. Remember to initialize this, server-people.
61 Comstack should now support the WAIS protocol in TCP/IP mode. Note
62 that this does not extend to ODR and ASN.
64 Comstack allows insertion of established socket (primarily for
65 inetd-operation of servers). Doc updated.
67 Front-end server can now start from the inetd in TCP mode. Doc
74 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
75 the rank and record number.
77 Adjustments to the frontend server.
79 Fixed diagnostic BER dumper. It ignored the file argument.
83 Various changes to retrieval module.
85 Changed the union discriminators of the protocol files from enums to
86 ints paired with #defines.
88 *Changed oident.class to oident.oclass to avoid a reserved word in C++
91 *Changed operator in the RPN structure to 'roperator', again to avoid a
94 Fixed problems in Explain decoders/encoders.
98 Memory bug in log module fixed.
102 Occasional malloc() of 0 bytes fixed in d1_espec.c.
104 Bug in Explain DatabaseInfo module fixed.
106 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
110 The shift to v1.0 signals that we now consider the *core* functionality
111 of YAZ reasonably stable (the core being more or less equivalent to
112 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
113 tested (Explain not at all - though that will happen soonish).
115 Minor changes to code to support Windows port.
117 Various minor changes after we're getting to use GRS-1 & co. more.
119 Added Espec-1 format.
121 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
122 of the protocol and it cannot be selected when encoding (maps into 'string'
123 when decoding). Needed to talk to some servers.
125 Demo client can request simple element set names.
127 Added Diagnostic Format encoders/decoders.
129 Added simple Close handling to frontend server (no hooks for resource
130 reporting yet), and demonstration client.
132 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
136 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
137 handled incorrectly when records were requested in the searchResponse. This
138 will only affect you if you use the frontend-server.
140 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
141 Test-client will ask for and print GRS1. Ztest will return dummy records
144 Added Explain encoders/decoders to the service-level API. Untested.
146 Added Extended Services: Item Order encoders and decoders to the Service-
147 level API. Untested. We could use a recent copy of the pertinent bits
148 of the ILL protocol to add those bits.
150 Added diagnostic format 1 encoders/decoders to the service-level API.
153 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
154 odr_cons.c, which causes a more correct output.
156 Fixed handling of searchRequest in frontend server. NextResultSetPosition
157 was always set to 0 when no records were requested in the searchRequest.
159 * Added better external-handling. This shouldn't harm old code that
160 *encodes* externals. It can break code that looks for a
161 'single-ASN1-type' representation, since those types that are known
162 are now decoded immediately. Look at the SUTRS sample code in
163 seshigh.c and client.c. Documentation updated.
165 Handling of structured records in bend_fetchresponse. Length -1 marks
166 structured record, type is deduced from format field.
169 Fairly quick maintenance release to add SUTRS support.
171 Fixed handling of SUTRS records in the demonstration client.
173 * Added format field to the bend_fetchrequest and bend_fetchresponce
174 structures of the backend API (frontend server). When the record is
175 returned, the value of the format field is mapped to an OID. The
176 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
177 of the record. The special value VAL_NONE in the bend_request means
178 that no specific format was requested by the client. Documentation
179 updated accordingly. Test server (ztest) will return a fixed dummy
180 SUTRS record if your client requests SUTRS.
182 Documentation updated accordingly.
184 You can now set external libraries and RANLIB support in the top-level
188 First public release.
