42 --- 1.2 1996/6/10 (1st anniversary release)

60 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
61 surrogate diagnostics were generated.
63 [retrieval] Allow multiple local values for attribute.
65 [retrieval] Allow multiple attributes per element in .abs files. index type.
67 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
71 Minor changes, mostly specific to Zebra's requirements (retrieval)
75 Repaired bug in frontend server when running multiple listening
76 endpoints in dynamic mode.
78 z_External() now won't break if a known, ASN.1 value comes encapsulated
79 in an octet-string. The value will pass through unmodified in an Odr_oct.
81 Added a bit of code to the demo client to decode & display
82 ASN.1-structured records represented in the octet-aligned branch of
83 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
85 Added z_ext_getentbyref() to the ASN module. Doc updated.
87 * Completed the SCAN definition in the ASN module. This may break SCAN
88 code based on older YAZ-versions at compile-time. The fix is easy -
91 * Added 'displayTerm' and OtherInformation to the TermInfo structure
92 under the SCAN definition. Remember to initialize this, server-people.
94 Comstack should now support the WAIS protocol in TCP/IP mode. Note
95 that this does not extend to ODR and ASN.
97 Comstack allows insertion of established socket (primarily for
98 inetd-operation of servers). Doc updated.
100 Front-end server can now start from the inetd in TCP mode. Doc
107 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
108 the rank and record number.
110 Adjustments to the frontend server.
112 Fixed diagnostic BER dumper. It ignored the file argument.
116 Various changes to retrieval module.
118 Changed the union discriminators of the protocol files from enums to
119 ints paired with #defines.
121 *Changed oident.class to oident.oclass to avoid a reserved word in C++
124 *Changed operator in the RPN structure to 'roperator', again to avoid a
127 Fixed problems in Explain decoders/encoders.
131 Memory bug in log module fixed.
135 Occasional malloc() of 0 bytes fixed in d1_espec.c.
137 Bug in Explain DatabaseInfo module fixed.
139 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
143 The shift to v1.0 signals that we now consider the *core* functionality
144 of YAZ reasonably stable (the core being more or less equivalent to
145 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
146 tested (Explain not at all - though that will happen soonish).
148 Minor changes to code to support Windows port.
150 Various minor changes after we're getting to use GRS-1 & co. more.
152 Added Espec-1 format.
154 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
155 of the protocol and it cannot be selected when encoding (maps into 'string'
156 when decoding). Needed to talk to some servers.
158 Demo client can request simple element set names.
160 Added Diagnostic Format encoders/decoders.
162 Added simple Close handling to frontend server (no hooks for resource
163 reporting yet), and demonstration client.
165 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
169 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
170 handled incorrectly when records were requested in the searchResponse. This
171 will only affect you if you use the frontend-server.
173 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
174 Test-client will ask for and print GRS1. Ztest will return dummy records
177 Added Explain encoders/decoders to the service-level API. Untested.
179 Added Extended Services: Item Order encoders and decoders to the Service-
180 level API. Untested. We could use a recent copy of the pertinent bits
181 of the ILL protocol to add those bits.
183 Added diagnostic format 1 encoders/decoders to the service-level API.
186 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
187 odr_cons.c, which causes a more correct output.
189 Fixed handling of searchRequest in frontend server. NextResultSetPosition
190 was always set to 0 when no records were requested in the searchRequest.
192 * Added better external-handling. This shouldn't harm old code that
193 *encodes* externals. It can break code that looks for a
194 'single-ASN1-type' representation, since those types that are known
195 are now decoded immediately. Look at the SUTRS sample code in
196 seshigh.c and client.c. Documentation updated.
198 Handling of structured records in bend_fetchresponse. Length -1 marks
199 structured record, type is deduced from format field.
202 Fairly quick maintenance release to add SUTRS support.
204 Fixed handling of SUTRS records in the demonstration client.
206 * Added format field to the bend_fetchrequest and bend_fetchresponce
207 structures of the backend API (frontend server). When the record is
208 returned, the value of the format field is mapped to an OID. The
209 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
210 of the record. The special value VAL_NONE in the bend_request means
211 that no specific format was requested by the client. Documentation
212 updated accordingly. Test server (ztest) will return a fixed dummy
213 SUTRS record if your client requests SUTRS.
215 Documentation updated accordingly.
217 You can now set external libraries and RANLIB support in the top-level
221 First public release.
