3 Add missing examples for Windows install.
5 Fix bug in regx filter to make it "greedy" again. This bug appeared
12 Fix XML error handling. Stop XML parse immediately if XML parse error
13 occur (i.e. produce one error only).
15 Zebra ignores "unsupported use attribute" for individual databases
16 when search multiple databases (unless all databases fail).
18 New filter grs.marcxml which works like grs.marc but produces MARCXML.
20 Added support for database deletion. It is possible to create/drop
21 a database from zebraidx utility. Note: only for isam:b.
23 Write zebrasrv.pid to lockdir.
25 Bug fix: result sets were not recovered correctly. Had to
26 add ODR handle for zebra_search_RPN in order to make it work.
28 Fixed a bug in regx filters that didn't do anchors (^) correctly.
30 Fixed a bug in searches with X-Path searches sometimes giving "extra"
33 Zebra server checks for zebrasrv.pid and refuses to start if it is already
34 locked by another (running) zebrasrv.
36 Fixed a bug with text being chunked in pieces for the grs.xml filter.
40 xelm code updates. xelm works regardless state of 'xpath enable/disable'
41 Avoid -L/usr/lib since that is already default library path.
43 Allow multiple updates within one transaction.
45 Fixed a bug with >2GB files (overflow in integer expression).
49 Fix linker error for Perl module.
51 Fix bug in and operation which in some cases could result in "extra"
52 hits. Bug was introduced in 1.3.5.
54 Fix bug in handling of schema conversion when producing numeric tags.
60 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
64 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
65 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
66 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
68 livrank: another experimental ranking algorithm. Source in livcode.c.
69 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
71 Contributed by Pete Mallinson, University of Liverpool.
73 Advanced MARC indexing. See doc/marc_indexing.xml
74 Oleg Kolobov <oleg at lib.tpu.ru>
76 Perl API updates and fixes.
77 Peter Popovics <pop at technomat.hu>
79 Fixed 'zebraidx delete'.
81 Implemented 'zebraidx clean'.
83 64-bit offsets for register files on WIN32 (no 2 GB limit).
85 Fixed a few memory leaks WRT sorting.
89 Fixed error handling : error code was not properly returned.
91 Support Truncation 104 (CCL).
95 Added missing source files for perl extension.
99 Implemented xelm directive.
101 Updated for newer version of YAZ (introduction of string schema).
103 Directory examples/zthes now part of distribution (was missing
104 in previous release).
106 New .abs directive, systag, that control where to put retrieval
107 information. The directive takes two arguments: system tag, element name.
108 System tag is one of : rank, sysno, size.
112 Perl Filter and Perl API. By Peter Popovics.
114 For zebra.cfg, if no profilePath is specified, directory
115 (prefix)/share/idzebra/tab
118 Zebra Examples in examples . Zebra tests in test.
120 Bug fix: sort index was not properly modified on
121 record updates/deletes.
123 Fix handling of character entities for sgml filter.
125 Move data1 to Zebra (used to be part of YAZ).
129 Fix character encoding of scan response terms.
131 Fix character decoding of scan request terms.
133 Fix ESpec handling (requires YAZ 1.9.1)
135 Fix searches for complete fields.
139 When name zebra is used in a filename or directory 'idzebra' is used
140 instead to avoid confusion with GNU zebra (routing software).
142 Zebra server stops with a fatal error if config file cannot be read.
144 New config setting, followLinks, that controls whether update of files
145 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
146 By default symbolic links are followed.
148 Fix MARC transfer . MARC fields had wrong data for multiple fields.
150 XML record reader moved from YAZ to Zebra, to make YAZ less
151 dependant on external libraries.
153 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
154 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
155 on systems that doesn't offer iconv.
157 XML record reader supports external system entities.
161 New .abs-directive "xpath" that takes one argument: "enable"
162 or "disable" to enable and disable XPath -indexing. If no "xpath"
163 direcive is found in .abs-file , XPath-indexing is disabled to ensure
164 backwards compatibility. For missing .abs-files XPath-indexing is
165 enabled so that such records are searchable.
167 Zebra warns about missing .abs-file only once (for each type).
169 Fixed a bug in file update where already-inserted files could
174 Zebra license changed to GNU GPL.
176 XPath-like queries used when RPN string attributes are used, eg.
177 @attr 1=/portal/title sometitle
178 @attr 1=/portal/title[@xml:lang=da] danishtitle
179 @attr 1=/portal/title/@xml:lang da
180 @attr 1=//title sometitle
182 Zebra uses UTF-8 internally:
183 1) New setting "encoding" for zebra.cfg that specifies encoding for
184 OCTET terms in queries and record encoding for most transfer syntaxes
185 (except those that use International Strings, such as GRS-1).
186 2) The encoding of International strings is UTF-8 by default. It
187 may be changed by character set negotiation. If character set
188 negotiation is in effect and if records are selected for conversion
189 these'll be converted to the selected character set - thus overriding
190 the encoding setting in zebra.cfg.
191 3) New directive "encoding" in .abs-files. This specifies the external
192 character encoding for files indexed by zebra. However, if records
193 themselves have an XML header that specifies and encoding that'll be used
196 XML filter (-t grs.xml).
198 Multiple registers. New setting in resource 'root' that holds base
199 directory for register(s). A group a databases may be put in separate
200 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
204 Fixes for Digital Unix
206 Implemented hits per term using USR:SearchResult-1.
208 New Zebra API. Locking system re-implemented.
210 --- 1.1.stable 2002/02/20
212 Rank weight can be controlled with attribute type 9. Default
213 value is 34. Recommended values between 1-36.
217 Updated for YAZ version 1.8.
219 Added support for termsets - a result set of terms matching
220 a given query. For @attr 8=<set> creates termset named <set>.
222 Added support for raw retrieval. Element Set Name R forces the
223 text filter which returns the record in its original form.
225 Added numerical sort - triggered by structure=numeric (4=109).
227 Remote record import using Z39.50 Extended Services and Segments.
229 Fixed bug where updating a database with user-defined attributes
230 could corrupt the register (bad storeKeys).
232 Multi-threaded version.
234 Fixed bug regarding proximity.
236 Documentation updates.
238 Fixed bug in record retrieval module that occured on 64-bit OSF
243 Fixed bug in makefile for WIN32.
245 Fixed bug in configure script - used bash-specific features.
249 Added support for multiple records in one file for filter grs.sgml.
251 Changed record index structure. New layout is incompatible with
252 previous releases. Added setting "recordcompression" to control
253 compression of records. Possible values are "none" (no
254 compression) and bzip2 (compression using libbz2).
256 Added XML transfer syntax support for retrieval of structured records.
257 Schema in CompSpec is recognised in retrieval of structured records.
259 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
260 that fails, the filter reads the file <filt>.flt (regx style filter).
262 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
263 Zebra's configure script automatically attempts to locate Tcl. For
264 manual Tcl configuration use option --with-tclconfig=<path> to specify
265 where Tcl's library files are located.
267 Implemented "compression" of Dictionary and ISAM system. Dictionary
270 Added "tagsysno" directive to zebra.cfg to control under which tag the
271 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
274 Added "tagrank" as above.
276 Changed file naming scheme for register files from <name>.mf.<no> to
279 Implemented "position"-flag for register type (as defined in
280 default.idx). When set to zero no position (or seqence number) is
281 saved in register for each word occurrence, thus saving some register
284 Implemented database mapping. Using mapdb one can specify a database
285 to be mapped to one or more physical databases. Usage:
286 mapdb <fromdb> <todb> ..
288 Added SOIF-filter. Thanks to Peter Valkenburg.
290 For the regx-filter "end element -record" may trigger a mark-of-record
291 if outer level is reached.
293 Tag sets may be typed in the reference to it. From the .abs-file the
294 "tagset" directive takes a third optional integer type for the tag set
295 referenced. From a .tag-file the "include" directive takes a third
296 optional type as well. The old "type" directive in the tag set itself
297 is still recognized but acts as the default type for the tag set.
299 Zebra supports the specification of arbitrary attributes sets, schemas
300 and tag sets, because of the change in YAZ' OID management system.
302 Fixed bug in Sort that caused it NOT to use character mapping as it
305 Zebra now uses GNU configure to generate Makefile(s).
307 Added un-optimised support for left and left/right truncation attributes.
309 Added support for relational operators on text when using RPN queries.
311 Added support for sort specifications in RPN queries. Type 7 specifies
312 'sort' where value 1=ascending, value 2=descending. The use attribute
313 specifies the field criteria as usual. The term specifies priority
314 where 0=first, 1=second, ...
316 Changed the way use attributes are specified in the recordId
319 Maximum number of databases in one Zebra register increased.
321 New setting, databasePath, which specifies that first directory during
322 update traversal is the database name (instead of a fixed one).
324 New setting, explainDatabase, which specifies that databases are
327 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
329 Implemented EXPLAIN database maintenance. Zebra automatically
330 generate - and update CategoryList, TargetInfo, DatabaseInfo,
331 AttributeSetInfo and AttributeDetails records at this stage. The
332 records may be transferred as GRS-1, SUTRS or Explain.
334 Fixed register spec so that colon isn't treated as size separator
335 unless followed by [0-9+-] in order to allow DOS drive specifications.
337 Fixed two bugs in ISAMC system.
339 Changed the way Zebra keeps its maintenance information about attribute
340 sets, available attributes, etc.. Records in "SGML" notation using an
341 EXPLAIN schema is now used when appropriate.
343 Bug fix: Index didn't handle update/insert/delete of the same record
344 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
345 first occurence of a record is considered.
347 Most searches now return correct number of hits.
349 New modular ranking system. Interested programmers are encouraged to
350 inspect rank1.c and improve the algorithm.
352 Bug fix: Lock files weren't removed as they should on NT.
354 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
355 specify a "sort register". Refer to the gils sample records which refer
356 to index type "s" which is specified as "sort" in the default.idx file.
357 Each sort criteria can either be Ascending or Descending and at most
358 three sort elements can be specified.
360 Bug fix: Character mapping didn't work for text files.
364 Simple ranked searches now return correct number of hits.
366 The test option (-s) only makes a read-lock on the index as well
367 as using read-only operations anywhere.
369 Moved towards generic character mapping. Configuration file default.idx
370 specifies character map files for register types w, p, u, etc.
372 Implemented "begin variant" for the sgml.regx - filter.
374 Fixed a few memory leaks.
376 Added support for C++, headers uses extern "C" for public definitions.
378 Bug fix: The show records facility (-s) only displayed information for
379 the first record in a file (and not for every record in the file).
381 Added option "-f <n>" to limit the logging of record operations. After
382 <n> records has been processed no logging is performed (unless errors
385 Bug fix: the compressed ISAM system didn't handle update operations
388 Added setting, "maxResultSetSize", to hold the number of records to
389 save in a result set.
391 Bug fix: Complete phrase did't work for search operations.
393 Bug fix: temporary result sets weren't deleted.
395 Reduced disk space for saved keys (storeKeys = 1).
397 Added optional, physical ANY (key replication)
399 Implemented proximity operator in search.
401 Bug fix: the path name buffers used by file match traversal routines
402 have been extended to support long file names.
404 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
405 configuration file. The resulting register without "storeKeys" is about
406 half the size, and the memory used by zebraidx during phase 2 (merge) is
407 reduced to a minimum.
409 Reworked the way Regexp-2 queries with error tolerance are handled and
410 specified. The documentation has been updated accordingly.
412 Bug fix: Zebrasrv didn't search correctly when queries contained masking
413 characters. This bug was introduced in 1.0a8.
415 Zebrasrv now tag records with the proper database name.
417 New settings, memMax and keyTmpDir.
419 Changed name of setting lockDir (previously called lockPath) and
420 setTmpDir (previously called tempSetPath).
422 Generalized and changed record type specifications. In short, there are:
424 grs.sgml structured, "SGML-like" syntax
425 grs.regx.<filter> structured, Regular expression filter
426 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
427 is the name of an abstract syntax file.
428 Bug fix: Result sets weren't sorted in operations involving boolean
429 operations with "ranked" operands.
433 Added national character-handling subsystem.
437 Small modifications to input filters and profiles.
439 Added support for SOIF syntax (with private OID).
443 Fixed buffer-size problem in indexing.
445 Added compression to temporary files for updating.
447 Added phrase registers.
449 Added dynamic mapping of search attribute to multiple termlists (ANY).
451 Scan support in multiple databases/registers.
453 Configuration settings are case-insensitive and single dash (-)
454 characters are ignored in comparisons.
456 The index processing ignores empty files - warning given.
458 New option to zebraidx (-V) displays version information.
462 Fixed problem in file-update system.
464 Fixed problem in shadow system; register was sometimes corrupted after
469 Fixed problems in the ISAM subsystem. Caused difficulties when updating
472 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
473 the rank and record number.
475 Fixed bug in the isam subsystem - caused a malfunction when accessing
476 words which occurred more than 10000 times.
478 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
481 Server can now run under inetd. Use option -i, and -w <directory> to
482 set working directory to desired location.
484 New zebraidx command: clean - removes temporary shadow files.
486 Fixed bug in ISAM system. Occurred rarely during register updates.
488 Logging during index merge phase is improved. The remaining running
491 Temporary files generated by zebraidx are removed after each run.
493 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
494 when doing scan operations in dictionaries with European characters.
498 A whole slew of updates, to make the first publicized release. Get the doc
503 Memory-problems in ISAM fixed. More blocktypes added to the default setup
504 to increase performance on larger databases.
506 Various minor changes in data management system.
510 A couple of portability-problems resolved.
512 Changed some malloc() to xmalloc().
