1 Possible compatibility problems with earlier versions marked with '*'.
3 * Removed member num_children from data1_node (in data1.h).
5 Made NT service interface part of the server library. The
6 function statserv_main uses the NT service when required and
7 calls the statserv_start / statserv_close routines.
10 Routine zget_SearchRequest fills resultSetName member with "default"
13 Fixed memory leak in server. Request queue member wasn't freed.
15 Fixed nmem_exit so that memory is freed.
19 Revised the CCL parser utility to be thread safe.
21 Added function, oid_ent_to_oid, to replace the function
22 oid_getoidbyent, which is not thread safe.
24 * Added nmem_init and nmem_exit to initialize and release
25 NMEM resources. Function nmem_init should be called once in the
26 initial thread before NMEM/ODR is used. statserv.c and client.c
27 have been changed accordingly. The change was necessary to make
28 NMEM thread safe. The NMEM memory pool is shared amongst threads
29 in a process. Unix-based applications will still work fine without
32 Added NT Services interface for the the Z39.50 (statserv) Server.
33 Refer to the ztest.c source on the usage.
35 Windows 95/NT port using MSV5.0. Project files are included in the
38 * Defined new 'global' handle for the retrieval (data1) system. The
39 new handled, data1_handle, describes the state of the data1 system.
40 This handle is passed as first argument to virtually all
41 data1 related routines. The functions data1_create and data1_destroy
42 creates and destroys a data1 handle respectively.
44 Added ODR encode stream member to all backend request structures
45 init, search, scan etc. This stream should be used to allocate all
46 memory used for the response when thread safe operation is needed.
48 Changed the comstack utility, cs_addstr, to be thread safe. The
49 returned hostname string returned by the function is now part the
52 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
53 function. The cs_straddr takes a COMSTACK handle as argument, so this
54 function must be used after cs_create and before bind/connect.
55 This function is thread safe.
57 Moved test server to 'ztest' directory - generic server code still
58 in 'server' directory.
60 Made prefix query (pquery.c) utility thread safe.
62 Added new function modifier YAZ_EXPORT to 'export' public DLL
63 functions when using windows (see include/yconfig.h).
65 Added definitions to the OID database (util/oid.c) (RVDM).
67 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
69 Added call to ccl_rpn_delete in client program.
71 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
72 release of RPN structure.
74 Added support for C++, headers uses extern "C" for public definitions.
77 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
78 Thanks to Ronald van der Meer (RVDM).
80 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
82 Added support for private extensions to the OID database
83 (oid_setprivateoids()). Thanks to RVDM.
85 Added optional, physical ANY (key replication)
87 Fixed null-reference problem in GRS-1 output filter.
89 Proximity operator added to Prefix Query Format (PQF).
91 In test client command "base" accepts multiple databases.
93 Fixed bug in cs_close stack that caused trouble with WINSOCK.
97 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
99 Smallish bug-fixes in the new encoders/decoders (explain).
101 Bug fixed in DeleteRequest.
103 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
105 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
107 Added SOIF syntax (using private OID for now) to retrieval module and client.
109 Added Update extended service.
111 Added SearchResult-1 additional info structure.
113 Added optional CCL (ISO8777) interpreter as separate module. Available
116 --- 1.2 1996/6/10 (1st anniversary release)
118 Added Summary record syntax. Lightly tested.
120 Added OPAC record syntax. Untested.
122 Added ResourceReport service encoders/decoders. Untested.
124 Fixed bug in z_Unit - wrong tagging on unitSystem.
126 Fixed bug in the DiagRecs decoder.
128 Added options for max PDU size and session timeout to frontend-server.
130 Added documentation of query-language parsers and other supporting utilities.
132 [frontend-server] Added Attribute set to the bend_scanrequest API.
134 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
135 surrogate diagnostics were generated.
137 [retrieval] Allow multiple local values for attribute.
139 [retrieval] Allow multiple attributes per element in .abs files. index type.
141 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
145 Minor changes, mostly specific to Zebra's requirements (retrieval)
149 Repaired bug in frontend server when running multiple listening
150 endpoints in dynamic mode.
152 z_External() now won't break if a known, ASN.1 value comes encapsulated
153 in an octet-string. The value will pass through unmodified in an Odr_oct.
155 Added a bit of code to the demo client to decode & display
156 ASN.1-structured records represented in the octet-aligned branch of
157 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
159 Added z_ext_getentbyref() to the ASN module. Doc updated.
161 * Completed the SCAN definition in the ASN module. This may break SCAN
162 code based on older YAZ-versions at compile-time. The fix is easy -
165 * Added 'displayTerm' and OtherInformation to the TermInfo structure
166 under the SCAN definition. Remember to initialize this, server-people.
168 Comstack should now support the WAIS protocol in TCP/IP mode. Note
169 that this does not extend to ODR and ASN.
171 Comstack allows insertion of established socket (primarily for
172 inetd-operation of servers). Doc updated.
174 Front-end server can now start from the inetd in TCP mode. Doc
181 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
182 the rank and record number.
184 Adjustments to the frontend server.
186 Fixed diagnostic BER dumper. It ignored the file argument.
190 Various changes to retrieval module.
192 Changed the union discriminators of the protocol files from enums to
193 ints paired with #defines.
195 *Changed oident.class to oident.oclass to avoid a reserved word in C++
198 *Changed operator in the RPN structure to 'roperator', again to avoid a
201 Fixed problems in Explain decoders/encoders.
205 Memory bug in log module fixed.
209 Occasional malloc() of 0 bytes fixed in d1_espec.c.
211 Bug in Explain DatabaseInfo module fixed.
213 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
217 The shift to v1.0 signals that we now consider the *core* functionality
218 of YAZ reasonably stable (the core being more or less equivalent to
219 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
220 tested (Explain not at all - though that will happen soonish).
222 Minor changes to code to support Windows port.
224 Various minor changes after we're getting to use GRS-1 & co. more.
226 Added Espec-1 format.
228 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
229 of the protocol and it cannot be selected when encoding (maps into 'string'
230 when decoding). Needed to talk to some servers.
232 Demo client can request simple element set names.
234 Added Diagnostic Format encoders/decoders.
236 Added simple Close handling to frontend server (no hooks for resource
237 reporting yet), and demonstration client.
239 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
243 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
244 handled incorrectly when records were requested in the searchResponse. This
245 will only affect you if you use the frontend-server.
247 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
248 Test-client will ask for and print GRS1. Ztest will return dummy records
251 Added Explain encoders/decoders to the service-level API. Untested.
253 Added Extended Services: Item Order encoders and decoders to the Service-
254 level API. Untested. We could use a recent copy of the pertinent bits
255 of the ILL protocol to add those bits.
257 Added diagnostic format 1 encoders/decoders to the service-level API.
260 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
261 odr_cons.c, which causes a more correct output.
263 Fixed handling of searchRequest in frontend server. NextResultSetPosition
264 was always set to 0 when no records were requested in the searchRequest.
266 * Added better external-handling. This shouldn't harm old code that
267 *encodes* externals. It can break code that looks for a
268 'single-ASN1-type' representation, since those types that are known
269 are now decoded immediately. Look at the SUTRS sample code in
270 seshigh.c and client.c. Documentation updated.
272 Handling of structured records in bend_fetchresponse. Length -1 marks
273 structured record, type is deduced from format field.
276 Fairly quick maintenance release to add SUTRS support.
278 Fixed handling of SUTRS records in the demonstration client.
280 * Added format field to the bend_fetchrequest and bend_fetchresponce
281 structures of the backend API (frontend server). When the record is
282 returned, the value of the format field is mapped to an OID. The
283 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
284 of the record. The special value VAL_NONE in the bend_request means
285 that no specific format was requested by the client. Documentation
286 updated accordingly. Test server (ztest) will return a fixed dummy
287 SUTRS record if your client requests SUTRS.
289 Documentation updated accordingly.
291 You can now set external libraries and RANLIB support in the top-level
295 First public release.
