1 Possible compatibility problems with earlier versions marked with '*'.
5 Revised the CCL parser utility to be thread safe.
7 Added function, oid_ent_to_oid, to replace the function
8 oid_getoidbyent, which is not thread safe.
10 * Added nmem_init and nmem_exit to initialize and release
11 NMEM resources. Function nmem_init should be called once in the
12 initial thread before NMEM/ODR is used. statserv.c and client.c
13 have been changed accordingly. The change was necessary to make
14 NMEM thread safe. The NMEM memory pool is shared amongst threads
17 Added NT Services interface for the the Z39.50 (statserv) Server.
18 Refer to the ztest.c source on the usage.
20 Windows 95/NT port using MSV5.0. Project files are included in the
23 * Defined new 'global' handle for the retrieval (data1) system. The
24 new handled, data1_handle, describes the state of the data1 system.
25 This handle is passed as first argument to virtually all
26 data1 related routines. The functions data1_create and data1_destroy
27 creates and destroys a data1 handle respectively.
29 Added ODR encode stream member to all backend request structures
30 init, search, scan etc. This stream should be used to allocate all
31 memory used for the response when thread safe operation is needed.
33 Changed the comstack utility, cs_addstr, to be thread safe. The
34 returned hostname string returned by the function is now part the
37 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
38 function. The cs_straddr takes a COMSTACK handle as argument, so this
39 function must be used after cs_create and before bind/connect.
40 This function is thread safe.
42 Moved test server to 'ztest' directory - generic server code still
43 in 'server' directory.
45 Made prefix query (pquery.c) utility thread safe.
47 Added new function modifier YAZ_EXPORT to 'export' public DLL
48 functions when using windows (see include/yconfig.h).
50 Added definitions to the OID database (util/oid.c) (RVDM).
52 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
54 Added call to ccl_rpn_delete in client program.
56 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
57 release of RPN structure.
59 Added support for C++, headers uses extern "C" for public definitions.
62 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
63 Thanks to Ronald van der Meer (RVDM).
65 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
67 Added support for private extensions to the OID database
68 (oid_setprivateoids()). Thanks to RVDM.
70 Added optional, physical ANY (key replication)
72 Fixed null-reference problem in GRS-1 output filter.
74 Proximity operator added to Prefix Query Format (PQF).
76 In test client command "base" accepts multiple databases.
78 Fixed bug in cs_close stack that caused trouble with WINSOCK.
82 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
84 Smallish bug-fixes in the new encoders/decoders (explain).
86 Bug fixed in DeleteRequest.
88 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
90 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
92 Added SOIF syntax (using private OID for now) to retrieval module and client.
94 Added Update extended service.
96 Added SearchResult-1 additional info structure.
98 Added optional CCL (ISO8777) interpreter as separate module. Available
101 --- 1.2 1996/6/10 (1st anniversary release)
103 Added Summary record syntax. Lightly tested.
105 Added OPAC record syntax. Untested.
107 Added ResourceReport service encoders/decoders. Untested.
109 Fixed bug in z_Unit - wrong tagging on unitSystem.
111 Fixed bug in the DiagRecs decoder.
113 Added options for max PDU size and session timeout to frontend-server.
115 Added documentation of query-language parsers and other supporting utilities.
117 [frontend-server] Added Attribute set to the bend_scanrequest API.
119 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
120 surrogate diagnostics were generated.
122 [retrieval] Allow multiple local values for attribute.
124 [retrieval] Allow multiple attributes per element in .abs files. index type.
126 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
130 Minor changes, mostly specific to Zebra's requirements (retrieval)
134 Repaired bug in frontend server when running multiple listening
135 endpoints in dynamic mode.
137 z_External() now won't break if a known, ASN.1 value comes encapsulated
138 in an octet-string. The value will pass through unmodified in an Odr_oct.
140 Added a bit of code to the demo client to decode & display
141 ASN.1-structured records represented in the octet-aligned branch of
142 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
144 Added z_ext_getentbyref() to the ASN module. Doc updated.
146 * Completed the SCAN definition in the ASN module. This may break SCAN
147 code based on older YAZ-versions at compile-time. The fix is easy -
150 * Added 'displayTerm' and OtherInformation to the TermInfo structure
151 under the SCAN definition. Remember to initialize this, server-people.
153 Comstack should now support the WAIS protocol in TCP/IP mode. Note
154 that this does not extend to ODR and ASN.
156 Comstack allows insertion of established socket (primarily for
157 inetd-operation of servers). Doc updated.
159 Front-end server can now start from the inetd in TCP mode. Doc
166 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
167 the rank and record number.
169 Adjustments to the frontend server.
171 Fixed diagnostic BER dumper. It ignored the file argument.
175 Various changes to retrieval module.
177 Changed the union discriminators of the protocol files from enums to
178 ints paired with #defines.
180 *Changed oident.class to oident.oclass to avoid a reserved word in C++
183 *Changed operator in the RPN structure to 'roperator', again to avoid a
186 Fixed problems in Explain decoders/encoders.
190 Memory bug in log module fixed.
194 Occasional malloc() of 0 bytes fixed in d1_espec.c.
196 Bug in Explain DatabaseInfo module fixed.
198 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
202 The shift to v1.0 signals that we now consider the *core* functionality
203 of YAZ reasonably stable (the core being more or less equivalent to
204 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
205 tested (Explain not at all - though that will happen soonish).
207 Minor changes to code to support Windows port.
209 Various minor changes after we're getting to use GRS-1 & co. more.
211 Added Espec-1 format.
213 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
214 of the protocol and it cannot be selected when encoding (maps into 'string'
215 when decoding). Needed to talk to some servers.
217 Demo client can request simple element set names.
219 Added Diagnostic Format encoders/decoders.
221 Added simple Close handling to frontend server (no hooks for resource
222 reporting yet), and demonstration client.
224 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
228 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
229 handled incorrectly when records were requested in the searchResponse. This
230 will only affect you if you use the frontend-server.
232 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
233 Test-client will ask for and print GRS1. Ztest will return dummy records
236 Added Explain encoders/decoders to the service-level API. Untested.
238 Added Extended Services: Item Order encoders and decoders to the Service-
239 level API. Untested. We could use a recent copy of the pertinent bits
240 of the ILL protocol to add those bits.
242 Added diagnostic format 1 encoders/decoders to the service-level API.
245 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
246 odr_cons.c, which causes a more correct output.
248 Fixed handling of searchRequest in frontend server. NextResultSetPosition
249 was always set to 0 when no records were requested in the searchRequest.
251 * Added better external-handling. This shouldn't harm old code that
252 *encodes* externals. It can break code that looks for a
253 'single-ASN1-type' representation, since those types that are known
254 are now decoded immediately. Look at the SUTRS sample code in
255 seshigh.c and client.c. Documentation updated.
257 Handling of structured records in bend_fetchresponse. Length -1 marks
258 structured record, type is deduced from format field.
261 Fairly quick maintenance release to add SUTRS support.
263 Fixed handling of SUTRS records in the demonstration client.
265 * Added format field to the bend_fetchrequest and bend_fetchresponce
266 structures of the backend API (frontend server). When the record is
267 returned, the value of the format field is mapped to an OID. The
268 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
269 of the record. The special value VAL_NONE in the bend_request means
270 that no specific format was requested by the client. Documentation
271 updated accordingly. Test server (ztest) will return a fixed dummy
272 SUTRS record if your client requests SUTRS.
274 Documentation updated accordingly.
276 You can now set external libraries and RANLIB support in the top-level
280 First public release.
