3 Fixed bug in makefile for WIN32.
5 Fixed bug in configure script - used bash-specific features.
9 The software was split in two products Zebra (for testing,
10 non-profit use) and the commercial product Z'mbol. Zebra no
11 longer supports INDEX UPDATES, i.e. zebraidx should be invoked only
12 once for each register. Refer to LICENSE.zebra for more info.
14 Added support for multiple records in one file for filter grs.sgml.
16 Changed record index structure. New layout is incompatible with
17 previous releases. Added setting "recordcompression" to control
18 compression of records. Possible values are "none" (no
19 compression) and bzip2 (compression using libbz2).
21 Added XML transfer syntax support for retrieval of structured records.
22 Schema in CompSpec is recognised in retrieval of structured records.
24 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
25 that fails, the filter reads the file <filt>.flt (regx style filter).
27 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
28 Zebra's configure script automatically attempts to locate Tcl. For
29 manual Tcl configuration use option --with-tclconfig=<path> to specify
30 where Tcl's library files are located.
32 Implemented "compression" of Dictionary and ISAM system. Dictionary
35 Added "tagsysno" directive to zebra.cfg to control under which tag the
36 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
39 Added "tagrank" as above.
41 Changed file naming scheme for register files from <name>.mf.<no> to
44 Implemented "position"-flag for register type (as defined in
45 default.idx). When set to zero no position (or seqence number) is
46 saved in register for each word occurrence, thus saving some register
49 Implemented database mapping. Using mapdb one can specify a database
50 to be mapped to one or more physical databases. Usage:
51 mapdb <fromdb> <todb> ..
53 Added SOIF-filter. Thanks to Peter Valkenburg.
55 For the regx-filter "end element -record" may trigger a mark-of-record
56 if outer level is reached.
58 Tag sets may be typed in the reference to it. From the .abs-file the
59 "tagset" directive takes a third optional integer type for the tag set
60 referenced. From a .tag-file the "include" directive takes a third
61 optional type as well. The old "type" directive in the tag set itself
62 is still recognized but acts as the default type for the tag set.
64 Zebra supports the specification of arbitrary attributes sets, schemas
65 and tag sets, because of the change in YAZ' OID management system.
67 Fixed bug in Sort that caused it NOT to use character mapping as it
70 Zebra now uses GNU configure to generate Makefile(s).
72 Added un-optimised support for left and left/right truncation attributes.
74 Added support for relational operators on text when using RPN queries.
76 Added support for sort specifications in RPN queries. Type 7 specifies
77 'sort' where value 1=ascending, value 2=descending. The use attribute
78 specifies the field criteria as usual. The term specifies priority
79 where 0=first, 1=second, ...
81 Changed the way use attributes are specified in the recordId
84 Maximum number of databases in one Zebra register increased.
86 New setting, databasePath, which specifies that first directory during
87 update traversal is the database name (instead of a fixed one).
89 New setting, explainDatabase, which specifies that databases are
92 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
94 Implemented EXPLAIN database maintenance. Zebra automatically
95 generate - and update CategoryList, TargetInfo, DatabaseInfo,
96 AttributeSetInfo and AttributeDetails records at this stage. The
97 records may be transferred as GRS-1, SUTRS or Explain.
99 Fixed register spec so that colon isn't treated as size separator
100 unless followed by [0-9+-] in order to allow DOS drive specifications.
102 Fixed two bugs in ISAMC system.
104 Changed the way Zebra keeps its maintenance information about attribute
105 sets, available attributes, etc.. Records in "SGML" notation using an
106 EXPLAIN schema is now used when appropriate.
108 Bug fix: Index didn't handle update/insert/delete of the same record
109 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
110 first occurence of a record is considered.
112 Most searches now return correct number of hits.
114 New modular ranking system. Interested programmers are encouraged to
115 inspect rank1.c and improve the algorithm.
117 Bug fix: Lock files weren't removed as they should on NT.
119 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
120 specify a "sort register". Refer to the gils sample records which refer
121 to index type "s" which is specified as "sort" in the default.idx file.
122 Each sort criteria can either be Ascending or Descending and at most
123 three sort elements can be specified.
125 Bug fix: Character mapping didn't work for text files.
129 Simple ranked searches now return correct number of hits.
131 The test option (-s) only makes a read-lock on the index as well
132 as using read-only operations anywhere.
134 Moved towards generic character mapping. Configuration file default.idx
135 specifies character map files for register types w, p, u, etc.
137 Implemented "begin variant" for the sgml.regx - filter.
139 Fixed a few memory leaks.
141 Added support for C++, headers uses extern "C" for public definitions.
143 Bug fix: The show records facility (-s) only displayed information for
144 the first record in a file (and not for every record in the file).
146 Added option "-f <n>" to limit the logging of record operations. After
147 <n> records has been processed no logging is performed (unless errors
150 Bug fix: the compressed ISAM system didn't handle update operations
153 Added setting, "maxResultSetSize", to hold the number of records to
154 save in a result set.
156 Bug fix: Complete phrase did't work for search operations.
158 Bug fix: temporary result sets weren't deleted.
160 Reduced disk space for saved keys (storeKeys = 1).
162 Added optional, physical ANY (key replication)
164 Implemented proximity operator in search.
166 Bug fix: the path name buffers used by file match traversal routines
167 have been extended to support long file names.
169 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
170 configuration file. The resulting register without "storeKeys" is about
171 half the size, and the memory used by zebraidx during phase 2 (merge) is
172 reduced to a minimum.
174 Reworked the way Regexp-2 queries with error tolerance are handled and
175 specified. The documentation has been updated accordingly.
177 Bug fix: Zebrasrv didn't search correctly when queries contained masking
178 characters. This bug was introduced in 1.0a8.
180 Zebrasrv now tag records with the proper database name.
182 New settings, memMax and keyTmpDir.
184 Changed name of setting lockDir (previously called lockPath) and
185 setTmpDir (previously called tempSetPath).
187 Generalized and changed record type specifications. In short, there are:
189 grs.sgml structured, "SGML-like" syntax
190 grs.regx.<filter> structured, Regular expression filter
191 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
192 is the name of an abstract syntax file.
193 Bug fix: Result sets weren't sorted in operations involving boolean
194 operations with "ranked" operands.
198 Added national character-handling subsystem.
202 Small modifications to input filters and profiles.
204 Added support for SOIF syntax (with private OID).
208 Fixed buffer-size problem in indexing.
210 Added compression to temporary files for updating.
212 Added phrase registers.
214 Added dynamic mapping of search attribute to multiple termlists (ANY).
216 Scan support in multiple databases/registers.
218 Configuration settings are case-insensitive and single dash (-)
219 characters are ignored in comparisons.
221 The index processing ignores empty files - warning given.
223 New option to zebraidx (-V) displays version information.
227 Fixed problem in file-update system.
229 Fixed problem in shadow system; register was sometimes corrupted after
234 Fixed problems in the ISAM subsystem. Caused difficulties when updating
237 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
238 the rank and record number.
240 Fixed bug in the isam subsystem - caused a malfunction when accessing
241 words which occurred more than 10000 times.
243 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
246 Server can now run under inetd. Use option -i, and -w <directory> to
247 set working directory to desired location.
249 New zebraidx command: clean - removes temporary shadow files.
251 Fixed bug in ISAM system. Occurred rarely during register updates.
253 Logging during index merge phase is improved. The remaining running
256 Temporary files generated by zebraidx are removed after each run.
258 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
259 when doing scan operations in dictionaries with European characters.
263 A whole slew of updates, to make the first publicized release. Get the doc
268 Memory-problems in ISAM fixed. More blocktypes added to the default setup
269 to increase performance on larger databases.
271 Various minor changes in data management system.
275 A couple of portability-problems resolved.
277 Changed some malloc() to xmalloc().
