4 Fixed bug #248: hit counts in combinatoric (and) searches in specific ..
6 Fixed bug #245: Time for getting records changes a lot based on record
9 Fixed bug #235: weird x-path results.
11 Avoid crash in ISAMB when isamb_pp_open gets ISAMB_POS = 0. In
12 this case EOF (no entries) is signalled. It fixes problem with
13 terms being deleted. See bug #109.
15 Fixed bug #169: Phrase term counts does not work. The bug exists in
18 Added mechanism to ignore leading articles when doing full-field indexing,
19 based on the character map files. See the manual for further discussion.
23 Fixed bug in record management. Releasing blocks could result in
26 Fixed bug in isam:b. A tree split could result in a lost item.
30 Add IDZebra.i to dist so that Perl extension builds again.
34 Added facility to make attibutes in grs.regx and grs.tcl filter using the
35 data command with argument -attribute <name> . The content of data is
36 the value of the attribute. This command should be used inside a
37 begin element , end element section.
39 Update zebra.nsi to NSIS 2.
41 Added a new 'cut' directive to charmaps (.chr files) which specifies that
42 only characters after the cutting char should be indexed.
44 Update Perl internals so that it matches the current Zebra API.
45 The recordGroup structure is no longer available. A group of resources
46 can still be referenced by setting groupName=>.. in various methods.
48 Maximum number of records to be sorted in a result set can be
49 specified by setting "sortmax". Default is 1000.
51 Allow use of string use attributes for regular attribute sets. The
52 name matches the name given in the attribute set file. All strings
53 starting with / are considered X-Path as usual.
55 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
56 element for XML tree. It may only pop off if -record is given.
58 Added grs.danbib filter - for Danish Bibliographic Centre.
60 Rename CHANGELOG to NEWS.
62 For text filter, return only header if elementSetName=H . elementSetName=R
63 returns contents only. Other elementSetName returns both header+content.
65 Added test for charmap and rusmarc.
67 Added feature charmaps (.chr) so that characters may be specified in
70 Fixed problem with encoding directive for charmap(.chr) files.
72 Allow Remote insert/delete/replace/update with record, recordIdNumber
73 (sysno) and/or recordIdOpaque(user supplied record Id). If both
74 IDs are omitted internal record ID match is assumed (recordId: - in
79 Fix bug. X-Path attribute expressions with spaces in them now works.
81 Fix base address for MARC output.
85 Fix bug with shadow and result set handling.
87 Implement MARCXML to ISO2709 conversion.
91 Add missing examples for Windows install.
93 Fix bug in regx filter to make it "greedy" again. This bug appeared
100 Fix XML error handling. Stop XML parse immediately if XML parse error
101 occur (i.e. produce one error only).
103 Zebra ignores "unsupported use attribute" for individual databases
104 when search multiple databases (unless all databases fail).
106 New filter grs.marcxml which works like grs.marc but produces MARCXML.
108 Added support for database deletion. It is possible to create/drop
109 a database from zebraidx utility. Note: only for isam:b.
111 Write zebrasrv.pid to lockdir.
113 Bug fix: result sets were not recovered correctly. Had to
114 add ODR handle for zebra_search_RPN in order to make it work.
116 Fixed a bug in regx filters that didn't do anchors (^) correctly.
118 Fixed a bug in searches with X-Path searches sometimes giving "extra"
121 Zebra server checks for zebrasrv.pid and refuses to start if it is already
122 locked by another (running) zebrasrv.
124 Fixed a bug with text being chunked in pieces for the grs.xml filter.
126 --- 1.3.11 2003/04/25
128 xelm code updates. xelm works regardless state of 'xpath enable/disable'
129 Avoid -L/usr/lib since that is already default library path.
131 Allow multiple updates within one transaction.
133 Fixed a bug with >2GB files (overflow in integer expression).
135 --- 1.3.10 2003/04/01
137 Fix linker error for Perl module.
139 Fix bug in and operation which in some cases could result in "extra"
140 hits. Bug was introduced in 1.3.5.
142 Fix bug in handling of schema conversion when producing numeric tags.
148 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
152 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
153 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
154 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
156 livrank: another experimental ranking algorithm. Source in livcode.c.
157 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
159 Contributed by Pete Mallinson, University of Liverpool.
161 Advanced MARC indexing. See doc/marc_indexing.xml
162 Oleg Kolobov <oleg at lib.tpu.ru>
164 Perl API updates and fixes.
165 Peter Popovics <pop at technomat.hu>
167 Fixed 'zebraidx delete'.
169 Implemented 'zebraidx clean'.
171 64-bit offsets for register files on WIN32 (no 2 GB limit).
173 Fixed a few memory leaks WRT sorting.
177 Fixed error handling : error code was not properly returned.
179 Support Truncation 104 (CCL).
183 Added missing source files for perl extension.
187 Implemented xelm directive.
189 Updated for newer version of YAZ (introduction of string schema).
191 Directory examples/zthes now part of distribution (was missing
192 in previous release).
194 New .abs directive, systag, that control where to put retrieval
195 information. The directive takes two arguments: system tag, element name.
196 System tag is one of : rank, sysno, size.
200 Perl Filter and Perl API. By Peter Popovics.
202 For zebra.cfg, if no profilePath is specified, directory
203 (prefix)/share/idzebra/tab
206 Zebra Examples in examples . Zebra tests in test.
208 Bug fix: sort index was not properly modified on
209 record updates/deletes.
211 Fix handling of character entities for sgml filter.
213 Move data1 to Zebra (used to be part of YAZ).
217 Fix character encoding of scan response terms.
219 Fix character decoding of scan request terms.
221 Fix ESpec handling (requires YAZ 1.9.1)
223 Fix searches for complete fields.
227 When name zebra is used in a filename or directory 'idzebra' is used
228 instead to avoid confusion with GNU zebra (routing software).
230 Zebra server stops with a fatal error if config file cannot be read.
232 New config setting, followLinks, that controls whether update of files
233 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
234 By default symbolic links are followed.
236 Fix MARC transfer . MARC fields had wrong data for multiple fields.
238 XML record reader moved from YAZ to Zebra, to make YAZ less
239 dependant on external libraries.
241 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
242 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
243 on systems that doesn't offer iconv.
245 XML record reader supports external system entities.
249 New .abs-directive "xpath" that takes one argument: "enable"
250 or "disable" to enable and disable XPath -indexing. If no "xpath"
251 direcive is found in .abs-file , XPath-indexing is disabled to ensure
252 backwards compatibility. For missing .abs-files XPath-indexing is
253 enabled so that such records are searchable.
255 Zebra warns about missing .abs-file only once (for each type).
257 Fixed a bug in file update where already-inserted files could
262 Zebra license changed to GNU GPL.
264 XPath-like queries used when RPN string attributes are used, eg.
265 @attr 1=/portal/title sometitle
266 @attr 1=/portal/title[@xml:lang=da] danishtitle
267 @attr 1=/portal/title/@xml:lang da
268 @attr 1=//title sometitle
270 Zebra uses UTF-8 internally:
271 1) New setting "encoding" for zebra.cfg that specifies encoding for
272 OCTET terms in queries and record encoding for most transfer syntaxes
273 (except those that use International Strings, such as GRS-1).
274 2) The encoding of International strings is UTF-8 by default. It
275 may be changed by character set negotiation. If character set
276 negotiation is in effect and if records are selected for conversion
277 these'll be converted to the selected character set - thus overriding
278 the encoding setting in zebra.cfg.
279 3) New directive "encoding" in .abs-files. This specifies the external
280 character encoding for files indexed by zebra. However, if records
281 themselves have an XML header that specifies and encoding that'll be used
284 XML filter (-t grs.xml).
286 Multiple registers. New setting in resource 'root' that holds base
287 directory for register(s). A group a databases may be put in separate
288 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
292 Fixes for Digital Unix
294 Implemented hits per term using USR:SearchResult-1.
296 New Zebra API. Locking system re-implemented.
298 --- 1.1.stable 2002/02/20
300 Rank weight can be controlled with attribute type 9. Default
301 value is 34. Recommended values between 1-36.
305 Updated for YAZ version 1.8.
307 Added support for termsets - a result set of terms matching
308 a given query. For @attr 8=<set> creates termset named <set>.
310 Added support for raw retrieval. Element Set Name R forces the
311 text filter which returns the record in its original form.
313 Added numerical sort - triggered by structure=numeric (4=109).
315 Remote record import using Z39.50 Extended Services and Segments.
317 Fixed bug where updating a database with user-defined attributes
318 could corrupt the register (bad storeKeys).
320 Multi-threaded version.
322 Fixed bug regarding proximity.
324 Documentation updates.
326 Fixed bug in record retrieval module that occured on 64-bit OSF
331 Fixed bug in makefile for WIN32.
333 Fixed bug in configure script - used bash-specific features.
337 Added support for multiple records in one file for filter grs.sgml.
339 Changed record index structure. New layout is incompatible with
340 previous releases. Added setting "recordcompression" to control
341 compression of records. Possible values are "none" (no
342 compression) and bzip2 (compression using libbz2).
344 Added XML transfer syntax support for retrieval of structured records.
345 Schema in CompSpec is recognised in retrieval of structured records.
347 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
348 that fails, the filter reads the file <filt>.flt (regx style filter).
350 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
351 Zebra's configure script automatically attempts to locate Tcl. For
352 manual Tcl configuration use option --with-tclconfig=<path> to specify
353 where Tcl's library files are located.
355 Implemented "compression" of Dictionary and ISAM system. Dictionary
358 Added "tagsysno" directive to zebra.cfg to control under which tag the
359 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
362 Added "tagrank" as above.
364 Changed file naming scheme for register files from <name>.mf.<no> to
367 Implemented "position"-flag for register type (as defined in
368 default.idx). When set to zero no position (or seqence number) is
369 saved in register for each word occurrence, thus saving some register
372 Implemented database mapping. Using mapdb one can specify a database
373 to be mapped to one or more physical databases. Usage:
374 mapdb <fromdb> <todb> ..
376 Added SOIF-filter. Thanks to Peter Valkenburg.
378 For the regx-filter "end element -record" may trigger a mark-of-record
379 if outer level is reached.
381 Tag sets may be typed in the reference to it. From the .abs-file the
382 "tagset" directive takes a third optional integer type for the tag set
383 referenced. From a .tag-file the "include" directive takes a third
384 optional type as well. The old "type" directive in the tag set itself
385 is still recognized but acts as the default type for the tag set.
387 Zebra supports the specification of arbitrary attributes sets, schemas
388 and tag sets, because of the change in YAZ' OID management system.
390 Fixed bug in Sort that caused it NOT to use character mapping as it
393 Zebra now uses GNU configure to generate Makefile(s).
395 Added un-optimised support for left and left/right truncation attributes.
397 Added support for relational operators on text when using RPN queries.
399 Added support for sort specifications in RPN queries. Type 7 specifies
400 'sort' where value 1=ascending, value 2=descending. The use attribute
401 specifies the field criteria as usual. The term specifies priority
402 where 0=first, 1=second, ...
404 Changed the way use attributes are specified in the recordId
407 Maximum number of databases in one Zebra register increased.
409 New setting, databasePath, which specifies that first directory during
410 update traversal is the database name (instead of a fixed one).
412 New setting, explainDatabase, which specifies that databases are
415 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
417 Implemented EXPLAIN database maintenance. Zebra automatically
418 generate - and update CategoryList, TargetInfo, DatabaseInfo,
419 AttributeSetInfo and AttributeDetails records at this stage. The
420 records may be transferred as GRS-1, SUTRS or Explain.
422 Fixed register spec so that colon isn't treated as size separator
423 unless followed by [0-9+-] in order to allow DOS drive specifications.
425 Fixed two bugs in ISAMC system.
427 Changed the way Zebra keeps its maintenance information about attribute
428 sets, available attributes, etc.. Records in "SGML" notation using an
429 EXPLAIN schema is now used when appropriate.
431 Bug fix: Index didn't handle update/insert/delete of the same record
432 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
433 first occurence of a record is considered.
435 Most searches now return correct number of hits.
437 New modular ranking system. Interested programmers are encouraged to
438 inspect rank1.c and improve the algorithm.
440 Bug fix: Lock files weren't removed as they should on NT.
442 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
443 specify a "sort register". Refer to the gils sample records which refer
444 to index type "s" which is specified as "sort" in the default.idx file.
445 Each sort criteria can either be Ascending or Descending and at most
446 three sort elements can be specified.
448 Bug fix: Character mapping didn't work for text files.
452 Simple ranked searches now return correct number of hits.
454 The test option (-s) only makes a read-lock on the index as well
455 as using read-only operations anywhere.
457 Moved towards generic character mapping. Configuration file default.idx
458 specifies character map files for register types w, p, u, etc.
460 Implemented "begin variant" for the sgml.regx - filter.
462 Fixed a few memory leaks.
464 Added support for C++, headers uses extern "C" for public definitions.
466 Bug fix: The show records facility (-s) only displayed information for
467 the first record in a file (and not for every record in the file).
469 Added option "-f <n>" to limit the logging of record operations. After
470 <n> records has been processed no logging is performed (unless errors
473 Bug fix: the compressed ISAM system didn't handle update operations
476 Added setting, "maxResultSetSize", to hold the number of records to
477 save in a result set.
479 Bug fix: Complete phrase did't work for search operations.
481 Bug fix: temporary result sets weren't deleted.
483 Reduced disk space for saved keys (storeKeys = 1).
485 Added optional, physical ANY (key replication)
487 Implemented proximity operator in search.
489 Bug fix: the path name buffers used by file match traversal routines
490 have been extended to support long file names.
492 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
493 configuration file. The resulting register without "storeKeys" is about
494 half the size, and the memory used by zebraidx during phase 2 (merge) is
495 reduced to a minimum.
497 Reworked the way Regexp-2 queries with error tolerance are handled and
498 specified. The documentation has been updated accordingly.
500 Bug fix: Zebrasrv didn't search correctly when queries contained masking
501 characters. This bug was introduced in 1.0a8.
503 Zebrasrv now tag records with the proper database name.
505 New settings, memMax and keyTmpDir.
507 Changed name of setting lockDir (previously called lockPath) and
508 setTmpDir (previously called tempSetPath).
510 Generalized and changed record type specifications. In short, there are:
512 grs.sgml structured, "SGML-like" syntax
513 grs.regx.<filter> structured, Regular expression filter
514 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
515 is the name of an abstract syntax file.
516 Bug fix: Result sets weren't sorted in operations involving boolean
517 operations with "ranked" operands.
521 Added national character-handling subsystem.
525 Small modifications to input filters and profiles.
527 Added support for SOIF syntax (with private OID).
531 Fixed buffer-size problem in indexing.
533 Added compression to temporary files for updating.
535 Added phrase registers.
537 Added dynamic mapping of search attribute to multiple termlists (ANY).
539 Scan support in multiple databases/registers.
541 Configuration settings are case-insensitive and single dash (-)
542 characters are ignored in comparisons.
544 The index processing ignores empty files - warning given.
546 New option to zebraidx (-V) displays version information.
550 Fixed problem in file-update system.
552 Fixed problem in shadow system; register was sometimes corrupted after
557 Fixed problems in the ISAM subsystem. Caused difficulties when updating
560 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
561 the rank and record number.
563 Fixed bug in the isam subsystem - caused a malfunction when accessing
564 words which occurred more than 10000 times.
566 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
569 Server can now run under inetd. Use option -i, and -w <directory> to
570 set working directory to desired location.
572 New zebraidx command: clean - removes temporary shadow files.
574 Fixed bug in ISAM system. Occurred rarely during register updates.
576 Logging during index merge phase is improved. The remaining running
579 Temporary files generated by zebraidx are removed after each run.
581 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
582 when doing scan operations in dictionaries with European characters.
586 A whole slew of updates, to make the first publicized release. Get the doc
591 Memory-problems in ISAM fixed. More blocktypes added to the default setup
592 to increase performance on larger databases.
594 Various minor changes in data management system.
598 A couple of portability-problems resolved.
600 Changed some malloc() to xmalloc().
