1 Possible compatibility problems with earlier versions marked with '*'.
5 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
6 surrogate diagnostics were generated.
8 Fixed bug in the DiagRecs decoder
10 Added options for max PDU size and session timeout to frontend-server.
12 Added documentation of query-language parsers and other utilities.
14 Added Attribute set to the bend_scanrequest API.
16 [retrieval] Allow multiple local values for attribute.
18 [retrieval] Allow multiple attributes per element in .abs files. index type.
22 Minor changes, mostly specific to Zebra
26 Repaired bug in frontend server when running multiple listening
27 endpoints in dynamic mode.
29 z_External() now won't break if a known, ASN.1 value comes encapsulated
30 in an octet-string. The value will pass through unmodified in an Odr_oct.
32 Added a bit of code to the demo client to decode & display
33 ASN.1-structured records represented in the octet-aligned branch of
34 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
36 Added z_ext_getentbyref() to the ASN module. Doc updated.
38 * Completed the SCAN definition in the ASN module. This may break SCAN
39 code based on older YAZ-versions at compile-time. The fix is easy -
42 * Added 'displayTerm' and OtherInformation to the TermInfo structure
43 under the SCAN definition. Remember to initialize this, server-people.
45 Comstack should now support the WAIS protocol in TCP/IP mode. Note
46 that this does not extend to ODR and ASN.
48 Comstack allows insertion of established socket (primarily for
49 inetd-operation of servers). Doc updated.
51 Front-end server can now start from the inetd in TCP mode. Doc
58 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
59 the rank and record number.
61 Adjustments to the frontend server.
63 Fixed diagnostic BER dumper. It ignored the file argument.
67 Various changes to retrieval module.
69 Changed the union discriminators of the protocol files from enums to
70 ints paired with #defines.
72 *Changed oident.class to oident.oclass to avoid a reserved word in C++
75 *Changed operator in the RPN structure to 'roperator', again to avoid a
78 Fixed problems in Explain decoders/encoders.
82 Memory bug in log module fixed.
86 Occasional malloc() of 0 bytes fixed in d1_espec.c.
88 Bug in Explain DatabaseInfo module fixed.
90 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
94 The shift to v1.0 signals that we now consider the *core* functionality
95 of YAZ reasonably stable (the core being more or less equivalent to
96 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
97 tested (Explain not at all - though that will happen soonish).
99 Minor changes to code to support Windows port.
101 Various minor changes after we're getting to use GRS-1 & co. more.
103 Added Espec-1 format.
105 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
106 of the protocol and it cannot be selected when encoding (maps into 'string'
107 when decoding). Needed to talk to some servers.
109 Demo client can request simple element set names.
111 Added Diagnostic Format encoders/decoders.
113 Added simple Close handling to frontend server (no hooks for resource
114 reporting yet), and demonstration client.
116 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
120 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
121 handled incorrectly when records were requested in the searchResponse. This
122 will only affect you if you use the frontend-server.
124 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
125 Test-client will ask for and print GRS1. Ztest will return dummy records
128 Added Explain encoders/decoders to the service-level API. Untested.
130 Added Extended Services: Item Order encoders and decoders to the Service-
131 level API. Untested. We could use a recent copy of the pertinent bits
132 of the ILL protocol to add those bits.
134 Added diagnostic format 1 encoders/decoders to the service-level API.
137 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
138 odr_cons.c, which causes a more correct output.
140 Fixed handling of searchRequest in frontend server. NextResultSetPosition
141 was always set to 0 when no records were requested in the searchRequest.
143 * Added better external-handling. This shouldn't harm old code that
144 *encodes* externals. It can break code that looks for a
145 'single-ASN1-type' representation, since those types that are known
146 are now decoded immediately. Look at the SUTRS sample code in
147 seshigh.c and client.c. Documentation updated.
149 Handling of structured records in bend_fetchresponse. Length -1 marks
150 structured record, type is deduced from format field.
153 Fairly quick maintenance release to add SUTRS support.
155 Fixed handling of SUTRS records in the demonstration client.
157 * Added format field to the bend_fetchrequest and bend_fetchresponce
158 structures of the backend API (frontend server). When the record is
159 returned, the value of the format field is mapped to an OID. The
160 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
161 of the record. The special value VAL_NONE in the bend_request means
162 that no specific format was requested by the client. Documentation
163 updated accordingly. Test server (ztest) will return a fixed dummy
164 SUTRS record if your client requests SUTRS.
166 Documentation updated accordingly.
168 You can now set external libraries and RANLIB support in the top-level
172 First public release.
