1 Implemented the 'equivalent' directive for .chr-files.
3 Added zebra_get_bfs to get BFile handle for session.
5 Added 'melm' directive to absyn format to simplify config files
6 for MARC-style databases. See tab/marc21.abs for an example.
8 Added bath-compliant definition file marc21.abs for use with MARC databases.
10 Added autoconf utility idzebra.m4 which defines --with-idzebra .
12 Added mechanism to ignore leading articles when doing full-field indexing,
13 based on the character map files. See the manual for further discussion.
15 Fixed bug in record management. Releasing blocks could result in
18 Fixed bug in isam:b. A tree split could result in a lost item.
20 Remove isamd. It's not been in use for a long time and isamb is better
23 Change SYSNO to be zint. Change pointers in isamc and isamb to zint.
24 Change block number in bfile/cfile to zint. zint is a long integer
25 (64-bit). This change practially removes register limits for Zebra.
27 Implement int-list encoding for ISAMs.
29 Added facility to make attibutes in grs.regx and grs.tcl filter using the
30 data command with argument -attribute <name> . The content of data is
31 the value of the attribute. This command should be used inside a
32 begin element , end element section.
34 Update zebra.nsi to NSIS 2.
36 Added a new 'cut' directive to charmaps (.chr files) which specifies that
37 only characters after the cutting char should be indexed.
39 Update Perl internals so that it matches the current Zebra API.
40 The recordGroup structure is no longer available. A group of resources
41 can still be referenced by setting groupName=>.. in various methods.
43 Maximum number of records to be sorted in a result set can be
44 specified by setting "sortmax". Default is 1000.
46 Allow use of string use attributes for regular attribute sets. The
47 name matches the name given in the attribute set file. All strings
48 starting with / are considered X-Path as usual.
50 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
51 element for XML tree. It may only pop off if -record is given.
53 Added grs.danbib filter - for Danish Bibliographic Centre.
55 Rename CHANGELOG to NEWS.
57 For text filter, return only header if elementSetName=H . elementSetName=R
58 returns contents only. Other elementSetName returns both header+content.
60 Added test for charmap and rusmarc.
62 Added feature charmaps (.chr) so that characters may be specified in
65 Fixed problem with encoding directive for charmap(.chr) files.
67 Allow Remote insert/delete/replace/update with record, recordIdNumber
68 (sysno) and/or recordIdOpaque(user supplied record Id). If both
69 IDs are omitted internal record ID match is assumed (recordId: - in
74 Fix bug. X-Path attribute expressions with spaces in them now works.
76 Fix base address for MARC output.
80 Fix bug with shadow and result set handling.
82 Implement MARCXML to ISO2709 conversion.
86 Add missing examples for Windows install.
88 Fix bug in regx filter to make it "greedy" again. This bug appeared
95 Fix XML error handling. Stop XML parse immediately if XML parse error
96 occur (i.e. produce one error only).
98 Zebra ignores "unsupported use attribute" for individual databases
99 when search multiple databases (unless all databases fail).
101 New filter grs.marcxml which works like grs.marc but produces MARCXML.
103 Added support for database deletion. It is possible to create/drop
104 a database from zebraidx utility. Note: only for isam:b.
106 Write zebrasrv.pid to lockdir.
108 Bug fix: result sets were not recovered correctly. Had to
109 add ODR handle for zebra_search_RPN in order to make it work.
111 Fixed a bug in regx filters that didn't do anchors (^) correctly.
113 Fixed a bug in searches with X-Path searches sometimes giving "extra"
116 Zebra server checks for zebrasrv.pid and refuses to start if it is already
117 locked by another (running) zebrasrv.
119 Fixed a bug with text being chunked in pieces for the grs.xml filter.
121 --- 1.3.11 2003/04/25
123 xelm code updates. xelm works regardless state of 'xpath enable/disable'
124 Avoid -L/usr/lib since that is already default library path.
126 Allow multiple updates within one transaction.
128 Fixed a bug with >2GB files (overflow in integer expression).
130 --- 1.3.10 2003/04/01
132 Fix linker error for Perl module.
134 Fix bug in and operation which in some cases could result in "extra"
135 hits. Bug was introduced in 1.3.5.
137 Fix bug in handling of schema conversion when producing numeric tags.
143 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
147 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
148 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
149 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
151 livrank: another experimental ranking algorithm. Source in livcode.c.
152 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
154 Contributed by Pete Mallinson, University of Liverpool.
156 Advanced MARC indexing. See doc/marc_indexing.xml
157 Oleg Kolobov <oleg at lib.tpu.ru>
159 Perl API updates and fixes.
160 Peter Popovics <pop at technomat.hu>
162 Fixed 'zebraidx delete'.
164 Implemented 'zebraidx clean'.
166 64-bit offsets for register files on WIN32 (no 2 GB limit).
168 Fixed a few memory leaks WRT sorting.
172 Fixed error handling : error code was not properly returned.
174 Support Truncation 104 (CCL).
178 Added missing source files for perl extension.
182 Implemented xelm directive.
184 Updated for newer version of YAZ (introduction of string schema).
186 Directory examples/zthes now part of distribution (was missing
187 in previous release).
189 New .abs directive, systag, that control where to put retrieval
190 information. The directive takes two arguments: system tag, element name.
191 System tag is one of : rank, sysno, size.
195 Perl Filter and Perl API. By Peter Popovics.
197 For zebra.cfg, if no profilePath is specified, directory
198 (prefix)/share/idzebra/tab
201 Zebra Examples in examples . Zebra tests in test.
203 Bug fix: sort index was not properly modified on
204 record updates/deletes.
206 Fix handling of character entities for sgml filter.
208 Move data1 to Zebra (used to be part of YAZ).
212 Fix character encoding of scan response terms.
214 Fix character decoding of scan request terms.
216 Fix ESpec handling (requires YAZ 1.9.1)
218 Fix searches for complete fields.
222 When name zebra is used in a filename or directory 'idzebra' is used
223 instead to avoid confusion with GNU zebra (routing software).
225 Zebra server stops with a fatal error if config file cannot be read.
227 New config setting, followLinks, that controls whether update of files
228 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
229 By default symbolic links are followed.
231 Fix MARC transfer . MARC fields had wrong data for multiple fields.
233 XML record reader moved from YAZ to Zebra, to make YAZ less
234 dependant on external libraries.
236 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
237 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
238 on systems that doesn't offer iconv.
240 XML record reader supports external system entities.
244 New .abs-directive "xpath" that takes one argument: "enable"
245 or "disable" to enable and disable XPath -indexing. If no "xpath"
246 direcive is found in .abs-file , XPath-indexing is disabled to ensure
247 backwards compatibility. For missing .abs-files XPath-indexing is
248 enabled so that such records are searchable.
250 Zebra warns about missing .abs-file only once (for each type).
252 Fixed a bug in file update where already-inserted files could
257 Zebra license changed to GNU GPL.
259 XPath-like queries used when RPN string attributes are used, eg.
260 @attr 1=/portal/title sometitle
261 @attr 1=/portal/title[@xml:lang=da] danishtitle
262 @attr 1=/portal/title/@xml:lang da
263 @attr 1=//title sometitle
265 Zebra uses UTF-8 internally:
266 1) New setting "encoding" for zebra.cfg that specifies encoding for
267 OCTET terms in queries and record encoding for most transfer syntaxes
268 (except those that use International Strings, such as GRS-1).
269 2) The encoding of International strings is UTF-8 by default. It
270 may be changed by character set negotiation. If character set
271 negotiation is in effect and if records are selected for conversion
272 these'll be converted to the selected character set - thus overriding
273 the encoding setting in zebra.cfg.
274 3) New directive "encoding" in .abs-files. This specifies the external
275 character encoding for files indexed by zebra. However, if records
276 themselves have an XML header that specifies and encoding that'll be used
279 XML filter (-t grs.xml).
281 Multiple registers. New setting in resource 'root' that holds base
282 directory for register(s). A group a databases may be put in separate
283 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
287 Fixes for Digital Unix
289 Implemented hits per term using USR:SearchResult-1.
291 New Zebra API. Locking system re-implemented.
293 --- 1.1.stable 2002/02/20
295 Rank weight can be controlled with attribute type 9. Default
296 value is 34. Recommended values between 1-36.
300 Updated for YAZ version 1.8.
302 Added support for termsets - a result set of terms matching
303 a given query. For @attr 8=<set> creates termset named <set>.
305 Added support for raw retrieval. Element Set Name R forces the
306 text filter which returns the record in its original form.
308 Added numerical sort - triggered by structure=numeric (4=109).
310 Remote record import using Z39.50 Extended Services and Segments.
312 Fixed bug where updating a database with user-defined attributes
313 could corrupt the register (bad storeKeys).
315 Multi-threaded version.
317 Fixed bug regarding proximity.
319 Documentation updates.
321 Fixed bug in record retrieval module that occured on 64-bit OSF
326 Fixed bug in makefile for WIN32.
328 Fixed bug in configure script - used bash-specific features.
332 Added support for multiple records in one file for filter grs.sgml.
334 Changed record index structure. New layout is incompatible with
335 previous releases. Added setting "recordcompression" to control
336 compression of records. Possible values are "none" (no
337 compression) and bzip2 (compression using libbz2).
339 Added XML transfer syntax support for retrieval of structured records.
340 Schema in CompSpec is recognised in retrieval of structured records.
342 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
343 that fails, the filter reads the file <filt>.flt (regx style filter).
345 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
346 Zebra's configure script automatically attempts to locate Tcl. For
347 manual Tcl configuration use option --with-tclconfig=<path> to specify
348 where Tcl's library files are located.
350 Implemented "compression" of Dictionary and ISAM system. Dictionary
353 Added "tagsysno" directive to zebra.cfg to control under which tag the
354 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
357 Added "tagrank" as above.
359 Changed file naming scheme for register files from <name>.mf.<no> to
362 Implemented "position"-flag for register type (as defined in
363 default.idx). When set to zero no position (or seqence number) is
364 saved in register for each word occurrence, thus saving some register
367 Implemented database mapping. Using mapdb one can specify a database
368 to be mapped to one or more physical databases. Usage:
369 mapdb <fromdb> <todb> ..
371 Added SOIF-filter. Thanks to Peter Valkenburg.
373 For the regx-filter "end element -record" may trigger a mark-of-record
374 if outer level is reached.
376 Tag sets may be typed in the reference to it. From the .abs-file the
377 "tagset" directive takes a third optional integer type for the tag set
378 referenced. From a .tag-file the "include" directive takes a third
379 optional type as well. The old "type" directive in the tag set itself
380 is still recognized but acts as the default type for the tag set.
382 Zebra supports the specification of arbitrary attributes sets, schemas
383 and tag sets, because of the change in YAZ' OID management system.
385 Fixed bug in Sort that caused it NOT to use character mapping as it
388 Zebra now uses GNU configure to generate Makefile(s).
390 Added un-optimised support for left and left/right truncation attributes.
392 Added support for relational operators on text when using RPN queries.
394 Added support for sort specifications in RPN queries. Type 7 specifies
395 'sort' where value 1=ascending, value 2=descending. The use attribute
396 specifies the field criteria as usual. The term specifies priority
397 where 0=first, 1=second, ...
399 Changed the way use attributes are specified in the recordId
402 Maximum number of databases in one Zebra register increased.
404 New setting, databasePath, which specifies that first directory during
405 update traversal is the database name (instead of a fixed one).
407 New setting, explainDatabase, which specifies that databases are
410 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
412 Implemented EXPLAIN database maintenance. Zebra automatically
413 generate - and update CategoryList, TargetInfo, DatabaseInfo,
414 AttributeSetInfo and AttributeDetails records at this stage. The
415 records may be transferred as GRS-1, SUTRS or Explain.
417 Fixed register spec so that colon isn't treated as size separator
418 unless followed by [0-9+-] in order to allow DOS drive specifications.
420 Fixed two bugs in ISAMC system.
422 Changed the way Zebra keeps its maintenance information about attribute
423 sets, available attributes, etc.. Records in "SGML" notation using an
424 EXPLAIN schema is now used when appropriate.
426 Bug fix: Index didn't handle update/insert/delete of the same record
427 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
428 first occurence of a record is considered.
430 Most searches now return correct number of hits.
432 New modular ranking system. Interested programmers are encouraged to
433 inspect rank1.c and improve the algorithm.
435 Bug fix: Lock files weren't removed as they should on NT.
437 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
438 specify a "sort register". Refer to the gils sample records which refer
439 to index type "s" which is specified as "sort" in the default.idx file.
440 Each sort criteria can either be Ascending or Descending and at most
441 three sort elements can be specified.
443 Bug fix: Character mapping didn't work for text files.
447 Simple ranked searches now return correct number of hits.
449 The test option (-s) only makes a read-lock on the index as well
450 as using read-only operations anywhere.
452 Moved towards generic character mapping. Configuration file default.idx
453 specifies character map files for register types w, p, u, etc.
455 Implemented "begin variant" for the sgml.regx - filter.
457 Fixed a few memory leaks.
459 Added support for C++, headers uses extern "C" for public definitions.
461 Bug fix: The show records facility (-s) only displayed information for
462 the first record in a file (and not for every record in the file).
464 Added option "-f <n>" to limit the logging of record operations. After
465 <n> records has been processed no logging is performed (unless errors
468 Bug fix: the compressed ISAM system didn't handle update operations
471 Added setting, "maxResultSetSize", to hold the number of records to
472 save in a result set.
474 Bug fix: Complete phrase did't work for search operations.
476 Bug fix: temporary result sets weren't deleted.
478 Reduced disk space for saved keys (storeKeys = 1).
480 Added optional, physical ANY (key replication)
482 Implemented proximity operator in search.
484 Bug fix: the path name buffers used by file match traversal routines
485 have been extended to support long file names.
487 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
488 configuration file. The resulting register without "storeKeys" is about
489 half the size, and the memory used by zebraidx during phase 2 (merge) is
490 reduced to a minimum.
492 Reworked the way Regexp-2 queries with error tolerance are handled and
493 specified. The documentation has been updated accordingly.
495 Bug fix: Zebrasrv didn't search correctly when queries contained masking
496 characters. This bug was introduced in 1.0a8.
498 Zebrasrv now tag records with the proper database name.
500 New settings, memMax and keyTmpDir.
502 Changed name of setting lockDir (previously called lockPath) and
503 setTmpDir (previously called tempSetPath).
505 Generalized and changed record type specifications. In short, there are:
507 grs.sgml structured, "SGML-like" syntax
508 grs.regx.<filter> structured, Regular expression filter
509 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
510 is the name of an abstract syntax file.
511 Bug fix: Result sets weren't sorted in operations involving boolean
512 operations with "ranked" operands.
516 Added national character-handling subsystem.
520 Small modifications to input filters and profiles.
522 Added support for SOIF syntax (with private OID).
526 Fixed buffer-size problem in indexing.
528 Added compression to temporary files for updating.
530 Added phrase registers.
532 Added dynamic mapping of search attribute to multiple termlists (ANY).
534 Scan support in multiple databases/registers.
536 Configuration settings are case-insensitive and single dash (-)
537 characters are ignored in comparisons.
539 The index processing ignores empty files - warning given.
541 New option to zebraidx (-V) displays version information.
545 Fixed problem in file-update system.
547 Fixed problem in shadow system; register was sometimes corrupted after
552 Fixed problems in the ISAM subsystem. Caused difficulties when updating
555 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
556 the rank and record number.
558 Fixed bug in the isam subsystem - caused a malfunction when accessing
559 words which occurred more than 10000 times.
561 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
564 Server can now run under inetd. Use option -i, and -w <directory> to
565 set working directory to desired location.
567 New zebraidx command: clean - removes temporary shadow files.
569 Fixed bug in ISAM system. Occurred rarely during register updates.
571 Logging during index merge phase is improved. The remaining running
574 Temporary files generated by zebraidx are removed after each run.
576 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
577 when doing scan operations in dictionaries with European characters.
581 A whole slew of updates, to make the first publicized release. Get the doc
586 Memory-problems in ISAM fixed. More blocktypes added to the default setup
587 to increase performance on larger databases.
589 Various minor changes in data management system.
593 A couple of portability-problems resolved.
595 Changed some malloc() to xmalloc().
