2 Zebra ignores "unsupported use attribute" for individual databases
3 when search multiple databases (unless all databases fail).
5 New filter grs.marcxml which works like grs.marc but produces MARCXML.
7 Added support for database deletion. It is possible to create/drop
8 a database from zebraidx utility.
10 Write zebrasrv.pid to lockdir.
12 Bug fix: result sets were not recovered correctly. Had to
13 add ODR handle for zebra_search_RPN in order to make it work.
15 Fixed a bug in regx filters that didn't do anchors (^) correctly.
17 Fixed a bug in searches with X-Path searches sometimes giving "extra"
20 Zebra server checks for zebrasrv.pid and refuses to start if it is already
21 locked by another (running) zebrasrv.
23 Fixed a bug with text being chunked in pieces for the grs.xml filter.
27 xelm code updates. xelm works regardless state of 'xpath enable/disable'
28 Avoid -L/usr/lib since that is already default library path.
30 Allow multiple updates within one transaction.
32 Fixed a bug with >2GB files (overflow in integer expression).
36 Fix linker error for Perl module.
38 Fix bug in and operation which in some cases could result in "extra"
39 hits. Bug was introduced in 1.3.5.
41 Fix bug in handling of schema conversion when producing numeric tags.
47 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
51 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
52 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
53 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
55 livrank: another experimental ranking algorithm. Source in livcode.c.
56 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
58 Contributed by Pete Mallinson, University of Liverpool.
60 Advanced MARC indexing. See doc/marc_indexing.xml
61 Oleg Kolobov <oleg at lib.tpu.ru>
63 Perl API updates and fixes.
64 Peter Popovics <pop at technomat.hu>
66 Fixed 'zebraidx delete'.
68 Implemented 'zebraidx clean'.
70 64-bit offsets for register files on WIN32 (no 2 GB limit).
72 Fixed a few memory leaks WRT sorting.
76 Fixed error handling : error code was not properly returned.
78 Support Truncation 104 (CCL).
82 Added missing source files for perl extension.
86 Implemented xelm directive.
88 Updated for newer version of YAZ (introduction of string schema).
90 Directory examples/zthes now part of distribution (was missing
93 New .abs directive, systag, that control where to put retrieval
94 information. The directive takes two arguments: system tag, element name.
95 System tag is one of : rank, sysno, size.
99 Perl Filter and Perl API. By Peter Popovics.
101 For zebra.cfg, if no profilePath is specified, directory
102 (prefix)/share/idzebra/tab
105 Zebra Examples in examples . Zebra tests in test.
107 Bug fix: sort index was not properly modified on
108 record updates/deletes.
110 Fix handling of character entities for sgml filter.
112 Move data1 to Zebra (used to be part of YAZ).
116 Fix character encoding of scan response terms.
118 Fix character decoding of scan request terms.
120 Fix ESpec handling (requires YAZ 1.9.1)
122 Fix searches for complete fields.
126 When name zebra is used in a filename or directory 'idzebra' is used
127 instead to avoid confusion with GNU zebra (routing software).
129 Zebra server stops with a fatal error if config file cannot be read.
131 New config setting, followLinks, that controls whether update of files
132 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
133 By default symbolic links are followed.
135 Fix MARC transfer . MARC fields had wrong data for multiple fields.
137 XML record reader moved from YAZ to Zebra, to make YAZ less
138 dependant on external libraries.
140 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
141 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
142 on systems that doesn't offer iconv.
144 XML record reader supports external system entities.
148 New .abs-directive "xpath" that takes one argument: "enable"
149 or "disable" to enable and disable XPath -indexing. If no "xpath"
150 direcive is found in .abs-file , XPath-indexing is disabled to ensure
151 backwards compatibility. For missing .abs-files XPath-indexing is
152 enabled so that such records are searchable.
154 Zebra warns about missing .abs-file only once (for each type).
156 Fixed a bug in file update where already-inserted files could
161 Zebra license changed to GNU GPL.
163 XPath-like queries used when RPN string attributes are used, eg.
164 @attr 1=/portal/title sometitle
165 @attr 1=/portal/title[@xml:lang=da] danishtitle
166 @attr 1=/portal/title/@xml:lang da
167 @attr 1=//title sometitle
169 Zebra uses UTF-8 internally:
170 1) New setting "encoding" for zebra.cfg that specifies encoding for
171 OCTET terms in queries and record encoding for most transfer syntaxes
172 (except those that use International Strings, such as GRS-1).
173 2) The encoding of International strings is UTF-8 by default. It
174 may be changed by character set negotiation. If character set
175 negotiation is in effect and if records are selected for conversion
176 these'll be converted to the selected character set - thus overriding
177 the encoding setting in zebra.cfg.
178 3) New directive "encoding" in .abs-files. This specifies the external
179 character encoding for files indexed by zebra. However, if records
180 themselves have an XML header that specifies and encoding that'll be used
183 XML filter (-t grs.xml).
185 Multiple registers. New setting in resource 'root' that holds base
186 directory for register(s). A group a databases may be put in separate
187 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
191 Fixes for Digital Unix
193 Implemented hits per term using USR:SearchResult-1.
195 New Zebra API. Locking system re-implemented.
197 --- 1.1.stable 2002/02/20
199 Rank weight can be controlled with attribute type 9. Default
200 value is 34. Recommended values between 1-36.
204 Updated for YAZ version 1.8.
206 Added support for termsets - a result set of terms matching
207 a given query. For @attr 8=<set> creates termset named <set>.
209 Added support for raw retrieval. Element Set Name R forces the
210 text filter which returns the record in its original form.
212 Added numerical sort - triggered by structure=numeric (4=109).
214 Remote record import using Z39.50 Extended Services and Segments.
216 Fixed bug where updating a database with user-defined attributes
217 could corrupt the register (bad storeKeys).
219 Multi-threaded version.
221 Fixed bug regarding proximity.
223 Documentation updates.
225 Fixed bug in record retrieval module that occured on 64-bit OSF
230 Fixed bug in makefile for WIN32.
232 Fixed bug in configure script - used bash-specific features.
236 Added support for multiple records in one file for filter grs.sgml.
238 Changed record index structure. New layout is incompatible with
239 previous releases. Added setting "recordcompression" to control
240 compression of records. Possible values are "none" (no
241 compression) and bzip2 (compression using libbz2).
243 Added XML transfer syntax support for retrieval of structured records.
244 Schema in CompSpec is recognised in retrieval of structured records.
246 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
247 that fails, the filter reads the file <filt>.flt (regx style filter).
249 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
250 Zebra's configure script automatically attempts to locate Tcl. For
251 manual Tcl configuration use option --with-tclconfig=<path> to specify
252 where Tcl's library files are located.
254 Implemented "compression" of Dictionary and ISAM system. Dictionary
257 Added "tagsysno" directive to zebra.cfg to control under which tag the
258 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
261 Added "tagrank" as above.
263 Changed file naming scheme for register files from <name>.mf.<no> to
266 Implemented "position"-flag for register type (as defined in
267 default.idx). When set to zero no position (or seqence number) is
268 saved in register for each word occurrence, thus saving some register
271 Implemented database mapping. Using mapdb one can specify a database
272 to be mapped to one or more physical databases. Usage:
273 mapdb <fromdb> <todb> ..
275 Added SOIF-filter. Thanks to Peter Valkenburg.
277 For the regx-filter "end element -record" may trigger a mark-of-record
278 if outer level is reached.
280 Tag sets may be typed in the reference to it. From the .abs-file the
281 "tagset" directive takes a third optional integer type for the tag set
282 referenced. From a .tag-file the "include" directive takes a third
283 optional type as well. The old "type" directive in the tag set itself
284 is still recognized but acts as the default type for the tag set.
286 Zebra supports the specification of arbitrary attributes sets, schemas
287 and tag sets, because of the change in YAZ' OID management system.
289 Fixed bug in Sort that caused it NOT to use character mapping as it
292 Zebra now uses GNU configure to generate Makefile(s).
294 Added un-optimised support for left and left/right truncation attributes.
296 Added support for relational operators on text when using RPN queries.
298 Added support for sort specifications in RPN queries. Type 7 specifies
299 'sort' where value 1=ascending, value 2=descending. The use attribute
300 specifies the field criteria as usual. The term specifies priority
301 where 0=first, 1=second, ...
303 Changed the way use attributes are specified in the recordId
306 Maximum number of databases in one Zebra register increased.
308 New setting, databasePath, which specifies that first directory during
309 update traversal is the database name (instead of a fixed one).
311 New setting, explainDatabase, which specifies that databases are
314 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
316 Implemented EXPLAIN database maintenance. Zebra automatically
317 generate - and update CategoryList, TargetInfo, DatabaseInfo,
318 AttributeSetInfo and AttributeDetails records at this stage. The
319 records may be transferred as GRS-1, SUTRS or Explain.
321 Fixed register spec so that colon isn't treated as size separator
322 unless followed by [0-9+-] in order to allow DOS drive specifications.
324 Fixed two bugs in ISAMC system.
326 Changed the way Zebra keeps its maintenance information about attribute
327 sets, available attributes, etc.. Records in "SGML" notation using an
328 EXPLAIN schema is now used when appropriate.
330 Bug fix: Index didn't handle update/insert/delete of the same record
331 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
332 first occurence of a record is considered.
334 Most searches now return correct number of hits.
336 New modular ranking system. Interested programmers are encouraged to
337 inspect rank1.c and improve the algorithm.
339 Bug fix: Lock files weren't removed as they should on NT.
341 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
342 specify a "sort register". Refer to the gils sample records which refer
343 to index type "s" which is specified as "sort" in the default.idx file.
344 Each sort criteria can either be Ascending or Descending and at most
345 three sort elements can be specified.
347 Bug fix: Character mapping didn't work for text files.
351 Simple ranked searches now return correct number of hits.
353 The test option (-s) only makes a read-lock on the index as well
354 as using read-only operations anywhere.
356 Moved towards generic character mapping. Configuration file default.idx
357 specifies character map files for register types w, p, u, etc.
359 Implemented "begin variant" for the sgml.regx - filter.
361 Fixed a few memory leaks.
363 Added support for C++, headers uses extern "C" for public definitions.
365 Bug fix: The show records facility (-s) only displayed information for
366 the first record in a file (and not for every record in the file).
368 Added option "-f <n>" to limit the logging of record operations. After
369 <n> records has been processed no logging is performed (unless errors
372 Bug fix: the compressed ISAM system didn't handle update operations
375 Added setting, "maxResultSetSize", to hold the number of records to
376 save in a result set.
378 Bug fix: Complete phrase did't work for search operations.
380 Bug fix: temporary result sets weren't deleted.
382 Reduced disk space for saved keys (storeKeys = 1).
384 Added optional, physical ANY (key replication)
386 Implemented proximity operator in search.
388 Bug fix: the path name buffers used by file match traversal routines
389 have been extended to support long file names.
391 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
392 configuration file. The resulting register without "storeKeys" is about
393 half the size, and the memory used by zebraidx during phase 2 (merge) is
394 reduced to a minimum.
396 Reworked the way Regexp-2 queries with error tolerance are handled and
397 specified. The documentation has been updated accordingly.
399 Bug fix: Zebrasrv didn't search correctly when queries contained masking
400 characters. This bug was introduced in 1.0a8.
402 Zebrasrv now tag records with the proper database name.
404 New settings, memMax and keyTmpDir.
406 Changed name of setting lockDir (previously called lockPath) and
407 setTmpDir (previously called tempSetPath).
409 Generalized and changed record type specifications. In short, there are:
411 grs.sgml structured, "SGML-like" syntax
412 grs.regx.<filter> structured, Regular expression filter
413 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
414 is the name of an abstract syntax file.
415 Bug fix: Result sets weren't sorted in operations involving boolean
416 operations with "ranked" operands.
420 Added national character-handling subsystem.
424 Small modifications to input filters and profiles.
426 Added support for SOIF syntax (with private OID).
430 Fixed buffer-size problem in indexing.
432 Added compression to temporary files for updating.
434 Added phrase registers.
436 Added dynamic mapping of search attribute to multiple termlists (ANY).
438 Scan support in multiple databases/registers.
440 Configuration settings are case-insensitive and single dash (-)
441 characters are ignored in comparisons.
443 The index processing ignores empty files - warning given.
445 New option to zebraidx (-V) displays version information.
449 Fixed problem in file-update system.
451 Fixed problem in shadow system; register was sometimes corrupted after
456 Fixed problems in the ISAM subsystem. Caused difficulties when updating
459 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
460 the rank and record number.
462 Fixed bug in the isam subsystem - caused a malfunction when accessing
463 words which occurred more than 10000 times.
465 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
468 Server can now run under inetd. Use option -i, and -w <directory> to
469 set working directory to desired location.
471 New zebraidx command: clean - removes temporary shadow files.
473 Fixed bug in ISAM system. Occurred rarely during register updates.
475 Logging during index merge phase is improved. The remaining running
478 Temporary files generated by zebraidx are removed after each run.
480 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
481 when doing scan operations in dictionaries with European characters.
485 A whole slew of updates, to make the first publicized release. Get the doc
490 Memory-problems in ISAM fixed. More blocktypes added to the default setup
491 to increase performance on larger databases.
493 Various minor changes in data management system.
497 A couple of portability-problems resolved.
499 Changed some malloc() to xmalloc().
