7 Using busy wait for file locking on NT.
11 64 bit NT file system support.
13 --- 1.1.1 2002/09/04 (branch for stable version)
15 Fix XML attributes for MARC reader.
17 Rank weight can be controlled with attribute type 9. Default
18 value is 34. Recommended values between 1-36.
22 Updated for YAZ version 1.8.
24 Added support for termsets - a result set of terms matching
25 a given query. For @attr 8=<set> creates termset named <set>.
27 Added support for raw retrieval. Element Set Name R forces the
28 text filter which returns the record in its original form.
30 Added numerical sort - triggered by structure=numeric (4=109).
32 Remote record import using Z39.50 Extended Services and Segments.
34 Fixed bug where updating a database with user-defined attributes
35 could corrupt the register (bad storeKeys).
37 Multi-threaded version.
39 Fixed bug regarding proximity.
41 Documentation updates.
43 Fixed bug in record retrieval module that occured on 64-bit OSF
48 Fixed bug in makefile for WIN32.
50 Fixed bug in configure script - used bash-specific features.
54 The software was split in two products Zebra (for testing,
55 non-profit use) and the commercial product Z'mbol. Zebra no
56 longer supports INDEX UPDATES, i.e. zebraidx should be invoked only
57 once for each register. Refer to LICENSE.zebra for more info.
59 Added support for multiple records in one file for filter grs.sgml.
61 Changed record index structure. New layout is incompatible with
62 previous releases. Added setting "recordcompression" to control
63 compression of records. Possible values are "none" (no
64 compression) and bzip2 (compression using libbz2).
66 Added XML transfer syntax support for retrieval of structured records.
67 Schema in CompSpec is recognised in retrieval of structured records.
69 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
70 that fails, the filter reads the file <filt>.flt (regx style filter).
72 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
73 Zebra's configure script automatically attempts to locate Tcl. For
74 manual Tcl configuration use option --with-tclconfig=<path> to specify
75 where Tcl's library files are located.
77 Implemented "compression" of Dictionary and ISAM system. Dictionary
80 Added "tagsysno" directive to zebra.cfg to control under which tag the
81 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
84 Added "tagrank" as above.
86 Changed file naming scheme for register files from <name>.mf.<no> to
89 Implemented "position"-flag for register type (as defined in
90 default.idx). When set to zero no position (or seqence number) is
91 saved in register for each word occurrence, thus saving some register
94 Implemented database mapping. Using mapdb one can specify a database
95 to be mapped to one or more physical databases. Usage:
96 mapdb <fromdb> <todb> ..
98 Added SOIF-filter. Thanks to Peter Valkenburg.
100 For the regx-filter "end element -record" may trigger a mark-of-record
101 if outer level is reached.
103 Tag sets may be typed in the reference to it. From the .abs-file the
104 "tagset" directive takes a third optional integer type for the tag set
105 referenced. From a .tag-file the "include" directive takes a third
106 optional type as well. The old "type" directive in the tag set itself
107 is still recognized but acts as the default type for the tag set.
109 Zebra supports the specification of arbitrary attributes sets, schemas
110 and tag sets, because of the change in YAZ' OID management system.
112 Fixed bug in Sort that caused it NOT to use character mapping as it
115 Zebra now uses GNU configure to generate Makefile(s).
117 Added un-optimised support for left and left/right truncation attributes.
119 Added support for relational operators on text when using RPN queries.
121 Added support for sort specifications in RPN queries. Type 7 specifies
122 'sort' where value 1=ascending, value 2=descending. The use attribute
123 specifies the field criteria as usual. The term specifies priority
124 where 0=first, 1=second, ...
126 Changed the way use attributes are specified in the recordId
129 Maximum number of databases in one Zebra register increased.
131 New setting, databasePath, which specifies that first directory during
132 update traversal is the database name (instead of a fixed one).
134 New setting, explainDatabase, which specifies that databases are
137 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
139 Implemented EXPLAIN database maintenance. Zebra automatically
140 generate - and update CategoryList, TargetInfo, DatabaseInfo,
141 AttributeSetInfo and AttributeDetails records at this stage. The
142 records may be transferred as GRS-1, SUTRS or Explain.
144 Fixed register spec so that colon isn't treated as size separator
145 unless followed by [0-9+-] in order to allow DOS drive specifications.
147 Fixed two bugs in ISAMC system.
149 Changed the way Zebra keeps its maintenance information about attribute
150 sets, available attributes, etc.. Records in "SGML" notation using an
151 EXPLAIN schema is now used when appropriate.
153 Bug fix: Index didn't handle update/insert/delete of the same record
154 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
155 first occurence of a record is considered.
157 Most searches now return correct number of hits.
159 New modular ranking system. Interested programmers are encouraged to
160 inspect rank1.c and improve the algorithm.
162 Bug fix: Lock files weren't removed as they should on NT.
164 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
165 specify a "sort register". Refer to the gils sample records which refer
166 to index type "s" which is specified as "sort" in the default.idx file.
167 Each sort criteria can either be Ascending or Descending and at most
168 three sort elements can be specified.
170 Bug fix: Character mapping didn't work for text files.
174 Simple ranked searches now return correct number of hits.
176 The test option (-s) only makes a read-lock on the index as well
177 as using read-only operations anywhere.
179 Moved towards generic character mapping. Configuration file default.idx
180 specifies character map files for register types w, p, u, etc.
182 Implemented "begin variant" for the sgml.regx - filter.
184 Fixed a few memory leaks.
186 Added support for C++, headers uses extern "C" for public definitions.
188 Bug fix: The show records facility (-s) only displayed information for
189 the first record in a file (and not for every record in the file).
191 Added option "-f <n>" to limit the logging of record operations. After
192 <n> records has been processed no logging is performed (unless errors
195 Bug fix: the compressed ISAM system didn't handle update operations
198 Added setting, "maxResultSetSize", to hold the number of records to
199 save in a result set.
201 Bug fix: Complete phrase did't work for search operations.
203 Bug fix: temporary result sets weren't deleted.
205 Reduced disk space for saved keys (storeKeys = 1).
207 Added optional, physical ANY (key replication)
209 Implemented proximity operator in search.
211 Bug fix: the path name buffers used by file match traversal routines
212 have been extended to support long file names.
214 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
215 configuration file. The resulting register without "storeKeys" is about
216 half the size, and the memory used by zebraidx during phase 2 (merge) is
217 reduced to a minimum.
219 Reworked the way Regexp-2 queries with error tolerance are handled and
220 specified. The documentation has been updated accordingly.
222 Bug fix: Zebrasrv didn't search correctly when queries contained masking
223 characters. This bug was introduced in 1.0a8.
225 Zebrasrv now tag records with the proper database name.
227 New settings, memMax and keyTmpDir.
229 Changed name of setting lockDir (previously called lockPath) and
230 setTmpDir (previously called tempSetPath).
232 Generalized and changed record type specifications. In short, there are:
234 grs.sgml structured, "SGML-like" syntax
235 grs.regx.<filter> structured, Regular expression filter
236 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
237 is the name of an abstract syntax file.
238 Bug fix: Result sets weren't sorted in operations involving boolean
239 operations with "ranked" operands.
243 Added national character-handling subsystem.
247 Small modifications to input filters and profiles.
249 Added support for SOIF syntax (with private OID).
253 Fixed buffer-size problem in indexing.
255 Added compression to temporary files for updating.
257 Added phrase registers.
259 Added dynamic mapping of search attribute to multiple termlists (ANY).
261 Scan support in multiple databases/registers.
263 Configuration settings are case-insensitive and single dash (-)
264 characters are ignored in comparisons.
266 The index processing ignores empty files - warning given.
268 New option to zebraidx (-V) displays version information.
272 Fixed problem in file-update system.
274 Fixed problem in shadow system; register was sometimes corrupted after
279 Fixed problems in the ISAM subsystem. Caused difficulties when updating
282 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
283 the rank and record number.
285 Fixed bug in the isam subsystem - caused a malfunction when accessing
286 words which occurred more than 10000 times.
288 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
291 Server can now run under inetd. Use option -i, and -w <directory> to
292 set working directory to desired location.
294 New zebraidx command: clean - removes temporary shadow files.
296 Fixed bug in ISAM system. Occurred rarely during register updates.
298 Logging during index merge phase is improved. The remaining running
301 Temporary files generated by zebraidx are removed after each run.
303 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
304 when doing scan operations in dictionaries with European characters.
308 A whole slew of updates, to make the first publicized release. Get the doc
313 Memory-problems in ISAM fixed. More blocktypes added to the default setup
314 to increase performance on larger databases.
316 Various minor changes in data management system.
320 A couple of portability-problems resolved.
322 Changed some malloc() to xmalloc().
