2 64-bit offsets for register files on WIN32.
6 Fixed error handling : error code was not properly returned.
8 Support Truncation 104 (CCL).
12 Added missing source files for perl extension.
16 Implemented xelm directive.
18 Updated for newer version of YAZ (introduction of string schema).
20 Directory examples/zthes now part of distribution (was missing
23 New .abs directive, systag, that control where to put retrieval
24 information. The directive takes two arguments: system tag, element name.
25 System tag is one of : rank, sysno, size.
29 Perl Filter and Perl API. By Peter Popovics.
31 For zebra.cfg, if no profilePath is specified, directory
32 (prefix)/share/idzebra/tab
35 Zebra Examples in examples . Zebra tests in test.
37 Bug fix: sort index was not properly modified on
38 record updates/deletes.
40 Fix handling of character entities for sgml filter.
42 Move data1 to Zebra (used to be part of YAZ).
46 Fix character encoding of scan response terms.
48 Fix character decoding of scan request terms.
50 Fix ESpec handling (requires YAZ 1.9.1)
52 Fix searches for complete fields.
56 When name zebra is used in a filename or directory 'idzebra' is used
57 instead to avoid confusion with GNU zebra (routing software).
59 Zebra server stops with a fatal error if config file cannot be read.
61 New config setting, followLinks, that controls whether update of files
62 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
63 By default symbolic links are followed.
65 Fix MARC transfer . MARC fields had wrong data for multiple fields.
67 XML record reader moved from YAZ to Zebra, to make YAZ less
68 dependant on external libraries.
70 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
71 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
72 on systems that doesn't offer iconv.
74 XML record reader supports external system entities.
78 New .abs-directive "xpath" that takes one argument: "enable"
79 or "disable" to enable and disable XPath -indexing. If no "xpath"
80 direcive is found in .abs-file , XPath-indexing is disabled to ensure
81 backwards compatibility. For missing .abs-files XPath-indexing is
82 enabled so that such records are searchable.
84 Zebra warns about missing .abs-file only once (for each type).
86 Fixed a bug in file update where already-inserted files could
91 Zebra license changed to GNU GPL.
93 XPath-like queries used when RPN string attributes are used, eg.
94 @attr 1=/portal/title sometitle
95 @attr 1=/portal/title[@xml:lang=da] danishtitle
96 @attr 1=/portal/title/@xml:lang da
97 @attr 1=//title sometitle
99 Zebra uses UTF-8 internally:
100 1) New setting "encoding" for zebra.cfg that specifies encoding for
101 OCTET terms in queries and record encoding for most transfer syntaxes
102 (except those that use International Strings, such as GRS-1).
103 2) The encoding of International strings is UTF-8 by default. It
104 may be changed by character set negotiation. If character set
105 negotiation is in effect and if records are selected for conversion
106 these'll be converted to the selected character set - thus overriding
107 the encoding setting in zebra.cfg.
108 3) New directive "encoding" in .abs-files. This specifies the external
109 character encoding for files indexed by zebra. However, if records
110 themselves have an XML header that specifies and encoding that'll be used
113 XML filter (-t grs.xml).
115 Multiple registers. New setting in resource 'root' that holds base
116 directory for register(s). A group a databases may be put in separate
117 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
121 Fixes for Digital Unix
123 Implemented hits per term using USR:SearchResult-1.
125 New Zebra API. Locking system re-implemented.
127 --- 1.1.stable 2002/02/20
129 Rank weight can be controlled with attribute type 9. Default
130 value is 34. Recommended values between 1-36.
134 Updated for YAZ version 1.8.
136 Added support for termsets - a result set of terms matching
137 a given query. For @attr 8=<set> creates termset named <set>.
139 Added support for raw retrieval. Element Set Name R forces the
140 text filter which returns the record in its original form.
142 Added numerical sort - triggered by structure=numeric (4=109).
144 Remote record import using Z39.50 Extended Services and Segments.
146 Fixed bug where updating a database with user-defined attributes
147 could corrupt the register (bad storeKeys).
149 Multi-threaded version.
151 Fixed bug regarding proximity.
153 Documentation updates.
155 Fixed bug in record retrieval module that occured on 64-bit OSF
160 Fixed bug in makefile for WIN32.
162 Fixed bug in configure script - used bash-specific features.
166 Added support for multiple records in one file for filter grs.sgml.
168 Changed record index structure. New layout is incompatible with
169 previous releases. Added setting "recordcompression" to control
170 compression of records. Possible values are "none" (no
171 compression) and bzip2 (compression using libbz2).
173 Added XML transfer syntax support for retrieval of structured records.
174 Schema in CompSpec is recognised in retrieval of structured records.
176 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
177 that fails, the filter reads the file <filt>.flt (regx style filter).
179 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
180 Zebra's configure script automatically attempts to locate Tcl. For
181 manual Tcl configuration use option --with-tclconfig=<path> to specify
182 where Tcl's library files are located.
184 Implemented "compression" of Dictionary and ISAM system. Dictionary
187 Added "tagsysno" directive to zebra.cfg to control under which tag the
188 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
191 Added "tagrank" as above.
193 Changed file naming scheme for register files from <name>.mf.<no> to
196 Implemented "position"-flag for register type (as defined in
197 default.idx). When set to zero no position (or seqence number) is
198 saved in register for each word occurrence, thus saving some register
201 Implemented database mapping. Using mapdb one can specify a database
202 to be mapped to one or more physical databases. Usage:
203 mapdb <fromdb> <todb> ..
205 Added SOIF-filter. Thanks to Peter Valkenburg.
207 For the regx-filter "end element -record" may trigger a mark-of-record
208 if outer level is reached.
210 Tag sets may be typed in the reference to it. From the .abs-file the
211 "tagset" directive takes a third optional integer type for the tag set
212 referenced. From a .tag-file the "include" directive takes a third
213 optional type as well. The old "type" directive in the tag set itself
214 is still recognized but acts as the default type for the tag set.
216 Zebra supports the specification of arbitrary attributes sets, schemas
217 and tag sets, because of the change in YAZ' OID management system.
219 Fixed bug in Sort that caused it NOT to use character mapping as it
222 Zebra now uses GNU configure to generate Makefile(s).
224 Added un-optimised support for left and left/right truncation attributes.
226 Added support for relational operators on text when using RPN queries.
228 Added support for sort specifications in RPN queries. Type 7 specifies
229 'sort' where value 1=ascending, value 2=descending. The use attribute
230 specifies the field criteria as usual. The term specifies priority
231 where 0=first, 1=second, ...
233 Changed the way use attributes are specified in the recordId
236 Maximum number of databases in one Zebra register increased.
238 New setting, databasePath, which specifies that first directory during
239 update traversal is the database name (instead of a fixed one).
241 New setting, explainDatabase, which specifies that databases are
244 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
246 Implemented EXPLAIN database maintenance. Zebra automatically
247 generate - and update CategoryList, TargetInfo, DatabaseInfo,
248 AttributeSetInfo and AttributeDetails records at this stage. The
249 records may be transferred as GRS-1, SUTRS or Explain.
251 Fixed register spec so that colon isn't treated as size separator
252 unless followed by [0-9+-] in order to allow DOS drive specifications.
254 Fixed two bugs in ISAMC system.
256 Changed the way Zebra keeps its maintenance information about attribute
257 sets, available attributes, etc.. Records in "SGML" notation using an
258 EXPLAIN schema is now used when appropriate.
260 Bug fix: Index didn't handle update/insert/delete of the same record
261 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
262 first occurence of a record is considered.
264 Most searches now return correct number of hits.
266 New modular ranking system. Interested programmers are encouraged to
267 inspect rank1.c and improve the algorithm.
269 Bug fix: Lock files weren't removed as they should on NT.
271 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
272 specify a "sort register". Refer to the gils sample records which refer
273 to index type "s" which is specified as "sort" in the default.idx file.
274 Each sort criteria can either be Ascending or Descending and at most
275 three sort elements can be specified.
277 Bug fix: Character mapping didn't work for text files.
281 Simple ranked searches now return correct number of hits.
283 The test option (-s) only makes a read-lock on the index as well
284 as using read-only operations anywhere.
286 Moved towards generic character mapping. Configuration file default.idx
287 specifies character map files for register types w, p, u, etc.
289 Implemented "begin variant" for the sgml.regx - filter.
291 Fixed a few memory leaks.
293 Added support for C++, headers uses extern "C" for public definitions.
295 Bug fix: The show records facility (-s) only displayed information for
296 the first record in a file (and not for every record in the file).
298 Added option "-f <n>" to limit the logging of record operations. After
299 <n> records has been processed no logging is performed (unless errors
302 Bug fix: the compressed ISAM system didn't handle update operations
305 Added setting, "maxResultSetSize", to hold the number of records to
306 save in a result set.
308 Bug fix: Complete phrase did't work for search operations.
310 Bug fix: temporary result sets weren't deleted.
312 Reduced disk space for saved keys (storeKeys = 1).
314 Added optional, physical ANY (key replication)
316 Implemented proximity operator in search.
318 Bug fix: the path name buffers used by file match traversal routines
319 have been extended to support long file names.
321 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
322 configuration file. The resulting register without "storeKeys" is about
323 half the size, and the memory used by zebraidx during phase 2 (merge) is
324 reduced to a minimum.
326 Reworked the way Regexp-2 queries with error tolerance are handled and
327 specified. The documentation has been updated accordingly.
329 Bug fix: Zebrasrv didn't search correctly when queries contained masking
330 characters. This bug was introduced in 1.0a8.
332 Zebrasrv now tag records with the proper database name.
334 New settings, memMax and keyTmpDir.
336 Changed name of setting lockDir (previously called lockPath) and
337 setTmpDir (previously called tempSetPath).
339 Generalized and changed record type specifications. In short, there are:
341 grs.sgml structured, "SGML-like" syntax
342 grs.regx.<filter> structured, Regular expression filter
343 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
344 is the name of an abstract syntax file.
345 Bug fix: Result sets weren't sorted in operations involving boolean
346 operations with "ranked" operands.
350 Added national character-handling subsystem.
354 Small modifications to input filters and profiles.
356 Added support for SOIF syntax (with private OID).
360 Fixed buffer-size problem in indexing.
362 Added compression to temporary files for updating.
364 Added phrase registers.
366 Added dynamic mapping of search attribute to multiple termlists (ANY).
368 Scan support in multiple databases/registers.
370 Configuration settings are case-insensitive and single dash (-)
371 characters are ignored in comparisons.
373 The index processing ignores empty files - warning given.
375 New option to zebraidx (-V) displays version information.
379 Fixed problem in file-update system.
381 Fixed problem in shadow system; register was sometimes corrupted after
386 Fixed problems in the ISAM subsystem. Caused difficulties when updating
389 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
390 the rank and record number.
392 Fixed bug in the isam subsystem - caused a malfunction when accessing
393 words which occurred more than 10000 times.
395 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
398 Server can now run under inetd. Use option -i, and -w <directory> to
399 set working directory to desired location.
401 New zebraidx command: clean - removes temporary shadow files.
403 Fixed bug in ISAM system. Occurred rarely during register updates.
405 Logging during index merge phase is improved. The remaining running
408 Temporary files generated by zebraidx are removed after each run.
410 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
411 when doing scan operations in dictionaries with European characters.
415 A whole slew of updates, to make the first publicized release. Get the doc
420 Memory-problems in ISAM fixed. More blocktypes added to the default setup
421 to increase performance on larger databases.
423 Various minor changes in data management system.
427 A couple of portability-problems resolved.
429 Changed some malloc() to xmalloc().
