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