4 Fixed bug in record management. Releasing blocks could result in
7 Fixed bug in isam:b. A tree split could result in a lost item.
11 Add IDZebra.i to dist so that Perl extension builds again.
15 Added facility to make attibutes in grs.regx and grs.tcl filter using the
16 data command with argument -attribute <name> . The content of data is
17 the value of the attribute. This command should be used inside a
18 begin element , end element section.
20 Update zebra.nsi to NSIS 2.
22 Added a new 'cut' directive to charmaps (.chr files) which specifies that
23 only characters after the cutting char should be indexed.
25 Update Perl internals so that it matches the current Zebra API.
26 The recordGroup structure is no longer available. A group of resources
27 can still be referenced by setting groupName=>.. in various methods.
29 Maximum number of records to be sorted in a result set can be
30 specified by setting "sortmax". Default is 1000.
32 Allow use of string use attributes for regular attribute sets. The
33 name matches the name given in the attribute set file. All strings
34 starting with / are considered X-Path as usual.
36 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
37 element for XML tree. It may only pop off if -record is given.
39 Added grs.danbib filter - for Danish Bibliographic Centre.
41 Rename CHANGELOG to NEWS.
43 For text filter, return only header if elementSetName=H . elementSetName=R
44 returns contents only. Other elementSetName returns both header+content.
46 Added test for charmap and rusmarc.
48 Added feature charmaps (.chr) so that characters may be specified in
51 Fixed problem with encoding directive for charmap(.chr) files.
53 Allow Remote insert/delete/replace/update with record, recordIdNumber
54 (sysno) and/or recordIdOpaque(user supplied record Id). If both
55 IDs are omitted internal record ID match is assumed (recordId: - in
60 Fix bug. X-Path attribute expressions with spaces in them now works.
62 Fix base address for MARC output.
66 Fix bug with shadow and result set handling.
68 Implement MARCXML to ISO2709 conversion.
72 Add missing examples for Windows install.
74 Fix bug in regx filter to make it "greedy" again. This bug appeared
81 Fix XML error handling. Stop XML parse immediately if XML parse error
82 occur (i.e. produce one error only).
84 Zebra ignores "unsupported use attribute" for individual databases
85 when search multiple databases (unless all databases fail).
87 New filter grs.marcxml which works like grs.marc but produces MARCXML.
89 Added support for database deletion. It is possible to create/drop
90 a database from zebraidx utility. Note: only for isam:b.
92 Write zebrasrv.pid to lockdir.
94 Bug fix: result sets were not recovered correctly. Had to
95 add ODR handle for zebra_search_RPN in order to make it work.
97 Fixed a bug in regx filters that didn't do anchors (^) correctly.
99 Fixed a bug in searches with X-Path searches sometimes giving "extra"
102 Zebra server checks for zebrasrv.pid and refuses to start if it is already
103 locked by another (running) zebrasrv.
105 Fixed a bug with text being chunked in pieces for the grs.xml filter.
107 --- 1.3.11 2003/04/25
109 xelm code updates. xelm works regardless state of 'xpath enable/disable'
110 Avoid -L/usr/lib since that is already default library path.
112 Allow multiple updates within one transaction.
114 Fixed a bug with >2GB files (overflow in integer expression).
116 --- 1.3.10 2003/04/01
118 Fix linker error for Perl module.
120 Fix bug in and operation which in some cases could result in "extra"
121 hits. Bug was introduced in 1.3.5.
123 Fix bug in handling of schema conversion when producing numeric tags.
129 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
133 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
134 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
135 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
137 livrank: another experimental ranking algorithm. Source in livcode.c.
138 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
140 Contributed by Pete Mallinson, University of Liverpool.
142 Advanced MARC indexing. See doc/marc_indexing.xml
143 Oleg Kolobov <oleg at lib.tpu.ru>
145 Perl API updates and fixes.
146 Peter Popovics <pop at technomat.hu>
148 Fixed 'zebraidx delete'.
150 Implemented 'zebraidx clean'.
152 64-bit offsets for register files on WIN32 (no 2 GB limit).
154 Fixed a few memory leaks WRT sorting.
158 Fixed error handling : error code was not properly returned.
160 Support Truncation 104 (CCL).
164 Added missing source files for perl extension.
168 Implemented xelm directive.
170 Updated for newer version of YAZ (introduction of string schema).
172 Directory examples/zthes now part of distribution (was missing
173 in previous release).
175 New .abs directive, systag, that control where to put retrieval
176 information. The directive takes two arguments: system tag, element name.
177 System tag is one of : rank, sysno, size.
181 Perl Filter and Perl API. By Peter Popovics.
183 For zebra.cfg, if no profilePath is specified, directory
184 (prefix)/share/idzebra/tab
187 Zebra Examples in examples . Zebra tests in test.
189 Bug fix: sort index was not properly modified on
190 record updates/deletes.
192 Fix handling of character entities for sgml filter.
194 Move data1 to Zebra (used to be part of YAZ).
198 Fix character encoding of scan response terms.
200 Fix character decoding of scan request terms.
202 Fix ESpec handling (requires YAZ 1.9.1)
204 Fix searches for complete fields.
208 When name zebra is used in a filename or directory 'idzebra' is used
209 instead to avoid confusion with GNU zebra (routing software).
211 Zebra server stops with a fatal error if config file cannot be read.
213 New config setting, followLinks, that controls whether update of files
214 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
215 By default symbolic links are followed.
217 Fix MARC transfer . MARC fields had wrong data for multiple fields.
219 XML record reader moved from YAZ to Zebra, to make YAZ less
220 dependant on external libraries.
222 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
223 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
224 on systems that doesn't offer iconv.
226 XML record reader supports external system entities.
230 New .abs-directive "xpath" that takes one argument: "enable"
231 or "disable" to enable and disable XPath -indexing. If no "xpath"
232 direcive is found in .abs-file , XPath-indexing is disabled to ensure
233 backwards compatibility. For missing .abs-files XPath-indexing is
234 enabled so that such records are searchable.
236 Zebra warns about missing .abs-file only once (for each type).
238 Fixed a bug in file update where already-inserted files could
243 Zebra license changed to GNU GPL.
245 XPath-like queries used when RPN string attributes are used, eg.
246 @attr 1=/portal/title sometitle
247 @attr 1=/portal/title[@xml:lang=da] danishtitle
248 @attr 1=/portal/title/@xml:lang da
249 @attr 1=//title sometitle
251 Zebra uses UTF-8 internally:
252 1) New setting "encoding" for zebra.cfg that specifies encoding for
253 OCTET terms in queries and record encoding for most transfer syntaxes
254 (except those that use International Strings, such as GRS-1).
255 2) The encoding of International strings is UTF-8 by default. It
256 may be changed by character set negotiation. If character set
257 negotiation is in effect and if records are selected for conversion
258 these'll be converted to the selected character set - thus overriding
259 the encoding setting in zebra.cfg.
260 3) New directive "encoding" in .abs-files. This specifies the external
261 character encoding for files indexed by zebra. However, if records
262 themselves have an XML header that specifies and encoding that'll be used
265 XML filter (-t grs.xml).
267 Multiple registers. New setting in resource 'root' that holds base
268 directory for register(s). A group a databases may be put in separate
269 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
273 Fixes for Digital Unix
275 Implemented hits per term using USR:SearchResult-1.
277 New Zebra API. Locking system re-implemented.
279 --- 1.1.stable 2002/02/20
281 Rank weight can be controlled with attribute type 9. Default
282 value is 34. Recommended values between 1-36.
286 Updated for YAZ version 1.8.
288 Added support for termsets - a result set of terms matching
289 a given query. For @attr 8=<set> creates termset named <set>.
291 Added support for raw retrieval. Element Set Name R forces the
292 text filter which returns the record in its original form.
294 Added numerical sort - triggered by structure=numeric (4=109).
296 Remote record import using Z39.50 Extended Services and Segments.
298 Fixed bug where updating a database with user-defined attributes
299 could corrupt the register (bad storeKeys).
301 Multi-threaded version.
303 Fixed bug regarding proximity.
305 Documentation updates.
307 Fixed bug in record retrieval module that occured on 64-bit OSF
312 Fixed bug in makefile for WIN32.
314 Fixed bug in configure script - used bash-specific features.
318 Added support for multiple records in one file for filter grs.sgml.
320 Changed record index structure. New layout is incompatible with
321 previous releases. Added setting "recordcompression" to control
322 compression of records. Possible values are "none" (no
323 compression) and bzip2 (compression using libbz2).
325 Added XML transfer syntax support for retrieval of structured records.
326 Schema in CompSpec is recognised in retrieval of structured records.
328 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
329 that fails, the filter reads the file <filt>.flt (regx style filter).
331 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
332 Zebra's configure script automatically attempts to locate Tcl. For
333 manual Tcl configuration use option --with-tclconfig=<path> to specify
334 where Tcl's library files are located.
336 Implemented "compression" of Dictionary and ISAM system. Dictionary
339 Added "tagsysno" directive to zebra.cfg to control under which tag the
340 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
343 Added "tagrank" as above.
345 Changed file naming scheme for register files from <name>.mf.<no> to
348 Implemented "position"-flag for register type (as defined in
349 default.idx). When set to zero no position (or seqence number) is
350 saved in register for each word occurrence, thus saving some register
353 Implemented database mapping. Using mapdb one can specify a database
354 to be mapped to one or more physical databases. Usage:
355 mapdb <fromdb> <todb> ..
357 Added SOIF-filter. Thanks to Peter Valkenburg.
359 For the regx-filter "end element -record" may trigger a mark-of-record
360 if outer level is reached.
362 Tag sets may be typed in the reference to it. From the .abs-file the
363 "tagset" directive takes a third optional integer type for the tag set
364 referenced. From a .tag-file the "include" directive takes a third
365 optional type as well. The old "type" directive in the tag set itself
366 is still recognized but acts as the default type for the tag set.
368 Zebra supports the specification of arbitrary attributes sets, schemas
369 and tag sets, because of the change in YAZ' OID management system.
371 Fixed bug in Sort that caused it NOT to use character mapping as it
374 Zebra now uses GNU configure to generate Makefile(s).
376 Added un-optimised support for left and left/right truncation attributes.
378 Added support for relational operators on text when using RPN queries.
380 Added support for sort specifications in RPN queries. Type 7 specifies
381 'sort' where value 1=ascending, value 2=descending. The use attribute
382 specifies the field criteria as usual. The term specifies priority
383 where 0=first, 1=second, ...
385 Changed the way use attributes are specified in the recordId
388 Maximum number of databases in one Zebra register increased.
390 New setting, databasePath, which specifies that first directory during
391 update traversal is the database name (instead of a fixed one).
393 New setting, explainDatabase, which specifies that databases are
396 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
398 Implemented EXPLAIN database maintenance. Zebra automatically
399 generate - and update CategoryList, TargetInfo, DatabaseInfo,
400 AttributeSetInfo and AttributeDetails records at this stage. The
401 records may be transferred as GRS-1, SUTRS or Explain.
403 Fixed register spec so that colon isn't treated as size separator
404 unless followed by [0-9+-] in order to allow DOS drive specifications.
406 Fixed two bugs in ISAMC system.
408 Changed the way Zebra keeps its maintenance information about attribute
409 sets, available attributes, etc.. Records in "SGML" notation using an
410 EXPLAIN schema is now used when appropriate.
412 Bug fix: Index didn't handle update/insert/delete of the same record
413 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
414 first occurence of a record is considered.
416 Most searches now return correct number of hits.
418 New modular ranking system. Interested programmers are encouraged to
419 inspect rank1.c and improve the algorithm.
421 Bug fix: Lock files weren't removed as they should on NT.
423 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
424 specify a "sort register". Refer to the gils sample records which refer
425 to index type "s" which is specified as "sort" in the default.idx file.
426 Each sort criteria can either be Ascending or Descending and at most
427 three sort elements can be specified.
429 Bug fix: Character mapping didn't work for text files.
433 Simple ranked searches now return correct number of hits.
435 The test option (-s) only makes a read-lock on the index as well
436 as using read-only operations anywhere.
438 Moved towards generic character mapping. Configuration file default.idx
439 specifies character map files for register types w, p, u, etc.
441 Implemented "begin variant" for the sgml.regx - filter.
443 Fixed a few memory leaks.
445 Added support for C++, headers uses extern "C" for public definitions.
447 Bug fix: The show records facility (-s) only displayed information for
448 the first record in a file (and not for every record in the file).
450 Added option "-f <n>" to limit the logging of record operations. After
451 <n> records has been processed no logging is performed (unless errors
454 Bug fix: the compressed ISAM system didn't handle update operations
457 Added setting, "maxResultSetSize", to hold the number of records to
458 save in a result set.
460 Bug fix: Complete phrase did't work for search operations.
462 Bug fix: temporary result sets weren't deleted.
464 Reduced disk space for saved keys (storeKeys = 1).
466 Added optional, physical ANY (key replication)
468 Implemented proximity operator in search.
470 Bug fix: the path name buffers used by file match traversal routines
471 have been extended to support long file names.
473 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
474 configuration file. The resulting register without "storeKeys" is about
475 half the size, and the memory used by zebraidx during phase 2 (merge) is
476 reduced to a minimum.
478 Reworked the way Regexp-2 queries with error tolerance are handled and
479 specified. The documentation has been updated accordingly.
481 Bug fix: Zebrasrv didn't search correctly when queries contained masking
482 characters. This bug was introduced in 1.0a8.
484 Zebrasrv now tag records with the proper database name.
486 New settings, memMax and keyTmpDir.
488 Changed name of setting lockDir (previously called lockPath) and
489 setTmpDir (previously called tempSetPath).
491 Generalized and changed record type specifications. In short, there are:
493 grs.sgml structured, "SGML-like" syntax
494 grs.regx.<filter> structured, Regular expression filter
495 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
496 is the name of an abstract syntax file.
497 Bug fix: Result sets weren't sorted in operations involving boolean
498 operations with "ranked" operands.
502 Added national character-handling subsystem.
506 Small modifications to input filters and profiles.
508 Added support for SOIF syntax (with private OID).
512 Fixed buffer-size problem in indexing.
514 Added compression to temporary files for updating.
516 Added phrase registers.
518 Added dynamic mapping of search attribute to multiple termlists (ANY).
520 Scan support in multiple databases/registers.
522 Configuration settings are case-insensitive and single dash (-)
523 characters are ignored in comparisons.
525 The index processing ignores empty files - warning given.
527 New option to zebraidx (-V) displays version information.
531 Fixed problem in file-update system.
533 Fixed problem in shadow system; register was sometimes corrupted after
538 Fixed problems in the ISAM subsystem. Caused difficulties when updating
541 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
542 the rank and record number.
544 Fixed bug in the isam subsystem - caused a malfunction when accessing
545 words which occurred more than 10000 times.
547 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
550 Server can now run under inetd. Use option -i, and -w <directory> to
551 set working directory to desired location.
553 New zebraidx command: clean - removes temporary shadow files.
555 Fixed bug in ISAM system. Occurred rarely during register updates.
557 Logging during index merge phase is improved. The remaining running
560 Temporary files generated by zebraidx are removed after each run.
562 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
563 when doing scan operations in dictionaries with European characters.
567 A whole slew of updates, to make the first publicized release. Get the doc
572 Memory-problems in ISAM fixed. More blocktypes added to the default setup
573 to increase performance on larger databases.
575 Various minor changes in data management system.
579 A couple of portability-problems resolved.
581 Changed some malloc() to xmalloc().
