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