1 Added 'dbperms' setting to zebra.cfg. Names file with lines of
2 format username: db1+...dbn, listing databases that user has access to.
3 Database-specific access control only happens for searching, at present.
5 Added zebra_set_approx_limit for a ZebraHandle (session). Results
6 will be approximate if hit count is greater than the limit specified.
8 Added support for term hit counts. This was not in place for earlier
9 1.4 versions, but is present in the 1.3 series. Bug #124.
11 Implemented the 'equivalent' directive for .chr-files.
13 Added zebra_get_bfs to get BFile handle for session.
15 Added 'melm' directive to absyn format to simplify config files
16 for MARC-style databases. See tab/marc21.abs for an example.
18 Added bath-compliant definition file marc21.abs for use with MARC databases.
20 Added autoconf utility idzebra.m4 which defines --with-idzebra .
22 Added mechanism to ignore leading articles when doing full-field indexing,
23 based on the character map files. See the manual for further discussion.
25 Fixed bug in record management. Releasing blocks could result in
28 Fixed bug in isam:b. A tree split could result in a lost item.
30 Remove isamd. It's not been in use for a long time and isamb is better
33 Change SYSNO to be zint. Change pointers in isamc and isamb to zint.
34 Change block number in bfile/cfile to zint. zint is a long integer
35 (64-bit). This change practially removes register limits for Zebra.
37 Implement int-list encoding for ISAMs.
39 Added facility to make attibutes in grs.regx and grs.tcl filter using the
40 data command with argument -attribute <name> . The content of data is
41 the value of the attribute. This command should be used inside a
42 begin element , end element section.
44 Update zebra.nsi to NSIS 2.
46 Added a new 'cut' directive to charmaps (.chr files) which specifies that
47 only characters after the cutting char should be indexed.
49 Update Perl internals so that it matches the current Zebra API.
50 The recordGroup structure is no longer available. A group of resources
51 can still be referenced by setting groupName=>.. in various methods.
53 Maximum number of records to be sorted in a result set can be
54 specified by setting "sortmax". Default is 1000.
56 Allow use of string use attributes for regular attribute sets. The
57 name matches the name given in the attribute set file. All strings
58 starting with / are considered X-Path as usual.
60 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
61 element for XML tree. It may only pop off if -record is given.
63 Added grs.danbib filter - for Danish Bibliographic Centre.
65 Rename CHANGELOG to NEWS.
67 For text filter, return only header if elementSetName=H . elementSetName=R
68 returns contents only. Other elementSetName returns both header+content.
70 Added test for charmap and rusmarc.
72 Added feature charmaps (.chr) so that characters may be specified in
75 Fixed problem with encoding directive for charmap(.chr) files.
77 Allow Remote insert/delete/replace/update with record, recordIdNumber
78 (sysno) and/or recordIdOpaque(user supplied record Id). If both
79 IDs are omitted internal record ID match is assumed (recordId: - in
84 Fix bug. X-Path attribute expressions with spaces in them now works.
86 Fix base address for MARC output.
90 Fix bug with shadow and result set handling.
92 Implement MARCXML to ISO2709 conversion.
96 Add missing examples for Windows install.
98 Fix bug in regx filter to make it "greedy" again. This bug appeared
103 --- 1.3.12 2003/09/08
105 Fix XML error handling. Stop XML parse immediately if XML parse error
106 occur (i.e. produce one error only).
108 Zebra ignores "unsupported use attribute" for individual databases
109 when search multiple databases (unless all databases fail).
111 New filter grs.marcxml which works like grs.marc but produces MARCXML.
113 Added support for database deletion. It is possible to create/drop
114 a database from zebraidx utility. Note: only for isam:b.
116 Write zebrasrv.pid to lockdir.
118 Bug fix: result sets were not recovered correctly. Had to
119 add ODR handle for zebra_search_RPN in order to make it work.
121 Fixed a bug in regx filters that didn't do anchors (^) correctly.
123 Fixed a bug in searches with X-Path searches sometimes giving "extra"
126 Zebra server checks for zebrasrv.pid and refuses to start if it is already
127 locked by another (running) zebrasrv.
129 Fixed a bug with text being chunked in pieces for the grs.xml filter.
131 --- 1.3.11 2003/04/25
133 xelm code updates. xelm works regardless state of 'xpath enable/disable'
134 Avoid -L/usr/lib since that is already default library path.
136 Allow multiple updates within one transaction.
138 Fixed a bug with >2GB files (overflow in integer expression).
140 --- 1.3.10 2003/04/01
142 Fix linker error for Perl module.
144 Fix bug in and operation which in some cases could result in "extra"
145 hits. Bug was introduced in 1.3.5.
147 Fix bug in handling of schema conversion when producing numeric tags.
153 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
157 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
158 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
159 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
161 livrank: another experimental ranking algorithm. Source in livcode.c.
162 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
164 Contributed by Pete Mallinson, University of Liverpool.
166 Advanced MARC indexing. See doc/marc_indexing.xml
167 Oleg Kolobov <oleg at lib.tpu.ru>
169 Perl API updates and fixes.
170 Peter Popovics <pop at technomat.hu>
172 Fixed 'zebraidx delete'.
174 Implemented 'zebraidx clean'.
176 64-bit offsets for register files on WIN32 (no 2 GB limit).
178 Fixed a few memory leaks WRT sorting.
182 Fixed error handling : error code was not properly returned.
184 Support Truncation 104 (CCL).
188 Added missing source files for perl extension.
192 Implemented xelm directive.
194 Updated for newer version of YAZ (introduction of string schema).
196 Directory examples/zthes now part of distribution (was missing
197 in previous release).
199 New .abs directive, systag, that control where to put retrieval
200 information. The directive takes two arguments: system tag, element name.
201 System tag is one of : rank, sysno, size.
205 Perl Filter and Perl API. By Peter Popovics.
207 For zebra.cfg, if no profilePath is specified, directory
208 (prefix)/share/idzebra/tab
211 Zebra Examples in examples . Zebra tests in test.
213 Bug fix: sort index was not properly modified on
214 record updates/deletes.
216 Fix handling of character entities for sgml filter.
218 Move data1 to Zebra (used to be part of YAZ).
222 Fix character encoding of scan response terms.
224 Fix character decoding of scan request terms.
226 Fix ESpec handling (requires YAZ 1.9.1)
228 Fix searches for complete fields.
232 When name zebra is used in a filename or directory 'idzebra' is used
233 instead to avoid confusion with GNU zebra (routing software).
235 Zebra server stops with a fatal error if config file cannot be read.
237 New config setting, followLinks, that controls whether update of files
238 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
239 By default symbolic links are followed.
241 Fix MARC transfer . MARC fields had wrong data for multiple fields.
243 XML record reader moved from YAZ to Zebra, to make YAZ less
244 dependant on external libraries.
246 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
247 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
248 on systems that doesn't offer iconv.
250 XML record reader supports external system entities.
254 New .abs-directive "xpath" that takes one argument: "enable"
255 or "disable" to enable and disable XPath -indexing. If no "xpath"
256 direcive is found in .abs-file , XPath-indexing is disabled to ensure
257 backwards compatibility. For missing .abs-files XPath-indexing is
258 enabled so that such records are searchable.
260 Zebra warns about missing .abs-file only once (for each type).
262 Fixed a bug in file update where already-inserted files could
267 Zebra license changed to GNU GPL.
269 XPath-like queries used when RPN string attributes are used, eg.
270 @attr 1=/portal/title sometitle
271 @attr 1=/portal/title[@xml:lang=da] danishtitle
272 @attr 1=/portal/title/@xml:lang da
273 @attr 1=//title sometitle
275 Zebra uses UTF-8 internally:
276 1) New setting "encoding" for zebra.cfg that specifies encoding for
277 OCTET terms in queries and record encoding for most transfer syntaxes
278 (except those that use International Strings, such as GRS-1).
279 2) The encoding of International strings is UTF-8 by default. It
280 may be changed by character set negotiation. If character set
281 negotiation is in effect and if records are selected for conversion
282 these'll be converted to the selected character set - thus overriding
283 the encoding setting in zebra.cfg.
284 3) New directive "encoding" in .abs-files. This specifies the external
285 character encoding for files indexed by zebra. However, if records
286 themselves have an XML header that specifies and encoding that'll be used
289 XML filter (-t grs.xml).
291 Multiple registers. New setting in resource 'root' that holds base
292 directory for register(s). A group a databases may be put in separate
293 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
297 Fixes for Digital Unix
299 Implemented hits per term using USR:SearchResult-1.
301 New Zebra API. Locking system re-implemented.
303 --- 1.1.stable 2002/02/20
305 Rank weight can be controlled with attribute type 9. Default
306 value is 34. Recommended values between 1-36.
310 Updated for YAZ version 1.8.
312 Added support for termsets - a result set of terms matching
313 a given query. For @attr 8=<set> creates termset named <set>.
315 Added support for raw retrieval. Element Set Name R forces the
316 text filter which returns the record in its original form.
318 Added numerical sort - triggered by structure=numeric (4=109).
320 Remote record import using Z39.50 Extended Services and Segments.
322 Fixed bug where updating a database with user-defined attributes
323 could corrupt the register (bad storeKeys).
325 Multi-threaded version.
327 Fixed bug regarding proximity.
329 Documentation updates.
331 Fixed bug in record retrieval module that occured on 64-bit OSF
336 Fixed bug in makefile for WIN32.
338 Fixed bug in configure script - used bash-specific features.
342 Added support for multiple records in one file for filter grs.sgml.
344 Changed record index structure. New layout is incompatible with
345 previous releases. Added setting "recordcompression" to control
346 compression of records. Possible values are "none" (no
347 compression) and bzip2 (compression using libbz2).
349 Added XML transfer syntax support for retrieval of structured records.
350 Schema in CompSpec is recognised in retrieval of structured records.
352 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
353 that fails, the filter reads the file <filt>.flt (regx style filter).
355 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
356 Zebra's configure script automatically attempts to locate Tcl. For
357 manual Tcl configuration use option --with-tclconfig=<path> to specify
358 where Tcl's library files are located.
360 Implemented "compression" of Dictionary and ISAM system. Dictionary
363 Added "tagsysno" directive to zebra.cfg to control under which tag the
364 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
367 Added "tagrank" as above.
369 Changed file naming scheme for register files from <name>.mf.<no> to
372 Implemented "position"-flag for register type (as defined in
373 default.idx). When set to zero no position (or seqence number) is
374 saved in register for each word occurrence, thus saving some register
377 Implemented database mapping. Using mapdb one can specify a database
378 to be mapped to one or more physical databases. Usage:
379 mapdb <fromdb> <todb> ..
381 Added SOIF-filter. Thanks to Peter Valkenburg.
383 For the regx-filter "end element -record" may trigger a mark-of-record
384 if outer level is reached.
386 Tag sets may be typed in the reference to it. From the .abs-file the
387 "tagset" directive takes a third optional integer type for the tag set
388 referenced. From a .tag-file the "include" directive takes a third
389 optional type as well. The old "type" directive in the tag set itself
390 is still recognized but acts as the default type for the tag set.
392 Zebra supports the specification of arbitrary attributes sets, schemas
393 and tag sets, because of the change in YAZ' OID management system.
395 Fixed bug in Sort that caused it NOT to use character mapping as it
398 Zebra now uses GNU configure to generate Makefile(s).
400 Added un-optimised support for left and left/right truncation attributes.
402 Added support for relational operators on text when using RPN queries.
404 Added support for sort specifications in RPN queries. Type 7 specifies
405 'sort' where value 1=ascending, value 2=descending. The use attribute
406 specifies the field criteria as usual. The term specifies priority
407 where 0=first, 1=second, ...
409 Changed the way use attributes are specified in the recordId
412 Maximum number of databases in one Zebra register increased.
414 New setting, databasePath, which specifies that first directory during
415 update traversal is the database name (instead of a fixed one).
417 New setting, explainDatabase, which specifies that databases are
420 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
422 Implemented EXPLAIN database maintenance. Zebra automatically
423 generate - and update CategoryList, TargetInfo, DatabaseInfo,
424 AttributeSetInfo and AttributeDetails records at this stage. The
425 records may be transferred as GRS-1, SUTRS or Explain.
427 Fixed register spec so that colon isn't treated as size separator
428 unless followed by [0-9+-] in order to allow DOS drive specifications.
430 Fixed two bugs in ISAMC system.
432 Changed the way Zebra keeps its maintenance information about attribute
433 sets, available attributes, etc.. Records in "SGML" notation using an
434 EXPLAIN schema is now used when appropriate.
436 Bug fix: Index didn't handle update/insert/delete of the same record
437 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
438 first occurence of a record is considered.
440 Most searches now return correct number of hits.
442 New modular ranking system. Interested programmers are encouraged to
443 inspect rank1.c and improve the algorithm.
445 Bug fix: Lock files weren't removed as they should on NT.
447 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
448 specify a "sort register". Refer to the gils sample records which refer
449 to index type "s" which is specified as "sort" in the default.idx file.
450 Each sort criteria can either be Ascending or Descending and at most
451 three sort elements can be specified.
453 Bug fix: Character mapping didn't work for text files.
457 Simple ranked searches now return correct number of hits.
459 The test option (-s) only makes a read-lock on the index as well
460 as using read-only operations anywhere.
462 Moved towards generic character mapping. Configuration file default.idx
463 specifies character map files for register types w, p, u, etc.
465 Implemented "begin variant" for the sgml.regx - filter.
467 Fixed a few memory leaks.
469 Added support for C++, headers uses extern "C" for public definitions.
471 Bug fix: The show records facility (-s) only displayed information for
472 the first record in a file (and not for every record in the file).
474 Added option "-f <n>" to limit the logging of record operations. After
475 <n> records has been processed no logging is performed (unless errors
478 Bug fix: the compressed ISAM system didn't handle update operations
481 Added setting, "maxResultSetSize", to hold the number of records to
482 save in a result set.
484 Bug fix: Complete phrase did't work for search operations.
486 Bug fix: temporary result sets weren't deleted.
488 Reduced disk space for saved keys (storeKeys = 1).
490 Added optional, physical ANY (key replication)
492 Implemented proximity operator in search.
494 Bug fix: the path name buffers used by file match traversal routines
495 have been extended to support long file names.
497 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
498 configuration file. The resulting register without "storeKeys" is about
499 half the size, and the memory used by zebraidx during phase 2 (merge) is
500 reduced to a minimum.
502 Reworked the way Regexp-2 queries with error tolerance are handled and
503 specified. The documentation has been updated accordingly.
505 Bug fix: Zebrasrv didn't search correctly when queries contained masking
506 characters. This bug was introduced in 1.0a8.
508 Zebrasrv now tag records with the proper database name.
510 New settings, memMax and keyTmpDir.
512 Changed name of setting lockDir (previously called lockPath) and
513 setTmpDir (previously called tempSetPath).
515 Generalized and changed record type specifications. In short, there are:
517 grs.sgml structured, "SGML-like" syntax
518 grs.regx.<filter> structured, Regular expression filter
519 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
520 is the name of an abstract syntax file.
521 Bug fix: Result sets weren't sorted in operations involving boolean
522 operations with "ranked" operands.
526 Added national character-handling subsystem.
530 Small modifications to input filters and profiles.
532 Added support for SOIF syntax (with private OID).
536 Fixed buffer-size problem in indexing.
538 Added compression to temporary files for updating.
540 Added phrase registers.
542 Added dynamic mapping of search attribute to multiple termlists (ANY).
544 Scan support in multiple databases/registers.
546 Configuration settings are case-insensitive and single dash (-)
547 characters are ignored in comparisons.
549 The index processing ignores empty files - warning given.
551 New option to zebraidx (-V) displays version information.
555 Fixed problem in file-update system.
557 Fixed problem in shadow system; register was sometimes corrupted after
562 Fixed problems in the ISAM subsystem. Caused difficulties when updating
565 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
566 the rank and record number.
568 Fixed bug in the isam subsystem - caused a malfunction when accessing
569 words which occurred more than 10000 times.
571 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
574 Server can now run under inetd. Use option -i, and -w <directory> to
575 set working directory to desired location.
577 New zebraidx command: clean - removes temporary shadow files.
579 Fixed bug in ISAM system. Occurred rarely during register updates.
581 Logging during index merge phase is improved. The remaining running
584 Temporary files generated by zebraidx are removed after each run.
586 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
587 when doing scan operations in dictionaries with European characters.
591 A whole slew of updates, to make the first publicized release. Get the doc
596 Memory-problems in ISAM fixed. More blocktypes added to the default setup
597 to increase performance on larger databases.
599 Various minor changes in data management system.
603 A couple of portability-problems resolved.
605 Changed some malloc() to xmalloc().
