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