41 Added support for special slement set _sysno_ which returns a
42 record ID for a record packed as a SUTRS record.
46 Documented authentication facility in Zebra. Added zebra.cfg directive
47 'passwd.c' which specifies user accounts file with encrypted passwords. The
48 directive 'passwd' specifies user accounts file with clear-text passwords.
49 The previous version of Zebra used plain/clear text depending on
50 configuration automatically. That caused upgrade trouble. Bug #356.
54 Depend on YAZ 2.0.18 or later in configure.
56 Fixed crash that could occur if ES update transaction failed.
58 Configure enables the use of the crypt API - if available.
60 Fixed bug #304: Fuzzy search regExpr-2 did not use proper error distance
63 Fixed bug #305: Scan now handles negative preferred-position-in-response.
65 Implemented the 'equivalent' directive for .chr-files.
69 For configure, support threading again. It was removed by mistake

89 Fixed bug #235: weird x-path results.
91 Avoid crash in ISAMB when isamb_pp_open gets ISAMB_POS = 0. In
92 this case EOF (no entries) is signalled. It fixes problem with
93 terms being deleted. See bug #109.
95 Fixed bug #169: Phrase term counts does not work. The bug exists in
98 Added mechanism to ignore leading articles when doing full-field indexing,
99 based on the character map files. See the manual for further discussion.
101 --- 1.3.18 2004/08/20
103 Fixed bug in record management. Releasing blocks could result in
106 Fixed bug in isam:b. A tree split could result in a lost item.
108 --- 1.3.17 2004/08/17
110 Add IDZebra.i to dist so that Perl extension builds again.
112 --- 1.3.16 2004/08/16
114 Added facility to make attibutes in grs.regx and grs.tcl filter using the
115 data command with argument -attribute <name> . The content of data is
116 the value of the attribute. This command should be used inside a
117 begin element , end element section.
119 Update zebra.nsi to NSIS 2.
121 Added a new 'cut' directive to charmaps (.chr files) which specifies that
122 only characters after the cutting char should be indexed.
124 Update Perl internals so that it matches the current Zebra API.
125 The recordGroup structure is no longer available. A group of resources
126 can still be referenced by setting groupName=>.. in various methods.
128 Maximum number of records to be sorted in a result set can be
129 specified by setting "sortmax". Default is 1000.
131 Allow use of string use attributes for regular attribute sets. The
132 name matches the name given in the attribute set file. All strings
133 starting with / are considered X-Path as usual.
135 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
136 element for XML tree. It may only pop off if -record is given.
138 Added grs.danbib filter - for Danish Bibliographic Centre.
140 Rename CHANGELOG to NEWS.
142 For text filter, return only header if elementSetName=H . elementSetName=R
143 returns contents only. Other elementSetName returns both header+content.
145 Added test for charmap and rusmarc.
147 Added feature charmaps (.chr) so that characters may be specified in
150 Fixed problem with encoding directive for charmap(.chr) files.
152 Allow Remote insert/delete/replace/update with record, recordIdNumber
153 (sysno) and/or recordIdOpaque(user supplied record Id). If both
154 IDs are omitted internal record ID match is assumed (recordId: - in
157 --- 1.3.15 2004/01/15

169 --- 1.3.13 2003/09/26
171 Add missing examples for Windows install.
173 Fix bug in regx filter to make it "greedy" again. This bug appeared
178 --- 1.3.12 2003/09/08
180 Fix XML error handling. Stop XML parse immediately if XML parse error
181 occur (i.e. produce one error only).
183 Zebra ignores "unsupported use attribute" for individual databases
184 when search multiple databases (unless all databases fail).
186 New filter grs.marcxml which works like grs.marc but produces MARCXML.
188 Added support for database deletion. It is possible to create/drop
189 a database from zebraidx utility. Note: only for isam:b.
191 Write zebrasrv.pid to lockdir.
193 Bug fix: result sets were not recovered correctly. Had to
194 add ODR handle for zebra_search_RPN in order to make it work.
196 Fixed a bug in regx filters that didn't do anchors (^) correctly.
198 Fixed a bug in searches with X-Path searches sometimes giving "extra"
201 Zebra server checks for zebrasrv.pid and refuses to start if it is already
202 locked by another (running) zebrasrv.
204 Fixed a bug with text being chunked in pieces for the grs.xml filter.
206 --- 1.3.11 2003/04/25
208 xelm code updates. xelm works regardless state of 'xpath enable/disable'
209 Avoid -L/usr/lib since that is already default library path.
211 Allow multiple updates within one transaction.

215 --- 1.3.10 2003/04/01
217 Fix linker error for Perl module.
219 Fix bug in and operation which in some cases could result in "extra"
220 hits. Bug was introduced in 1.3.5.
222 Fix bug in handling of schema conversion when producing numeric tags.
228 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
232 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
233 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
234 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
236 livrank: another experimental ranking algorithm. Source in livcode.c.
237 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
239 Contributed by Pete Mallinson, University of Liverpool.
241 Advanced MARC indexing. See doc/marc_indexing.xml
242 Oleg Kolobov <oleg at lib.tpu.ru>
244 Perl API updates and fixes.
245 Peter Popovics <pop at technomat.hu>
247 Fixed 'zebraidx delete'.
249 Implemented 'zebraidx clean'.
251 64-bit offsets for register files on WIN32 (no 2 GB limit).
253 Fixed a few memory leaks WRT sorting.
257 Fixed error handling : error code was not properly returned.
259 Support Truncation 104 (CCL).
263 Added missing source files for perl extension.
267 Implemented xelm directive.
269 Updated for newer version of YAZ (introduction of string schema).
271 Directory examples/zthes now part of distribution (was missing
272 in previous release).
274 New .abs directive, systag, that control where to put retrieval
275 information. The directive takes two arguments: system tag, element name.
276 System tag is one of : rank, sysno, size.
280 Perl Filter and Perl API. By Peter Popovics.
282 For zebra.cfg, if no profilePath is specified, directory
283 (prefix)/share/idzebra/tab
286 Zebra Examples in examples . Zebra tests in test.
288 Bug fix: sort index was not properly modified on
289 record updates/deletes.
291 Fix handling of character entities for sgml filter.
293 Move data1 to Zebra (used to be part of YAZ).
297 Fix character encoding of scan response terms.
299 Fix character decoding of scan request terms.
301 Fix ESpec handling (requires YAZ 1.9.1)
303 Fix searches for complete fields.
307 When name zebra is used in a filename or directory 'idzebra' is used
308 instead to avoid confusion with GNU zebra (routing software).
310 Zebra server stops with a fatal error if config file cannot be read.
312 New config setting, followLinks, that controls whether update of files
313 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
314 By default symbolic links are followed.
316 Fix MARC transfer . MARC fields had wrong data for multiple fields.
318 XML record reader moved from YAZ to Zebra, to make YAZ less
319 dependant on external libraries.
321 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
322 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
323 on systems that doesn't offer iconv.
325 XML record reader supports external system entities.
329 New .abs-directive "xpath" that takes one argument: "enable"
330 or "disable" to enable and disable XPath -indexing. If no "xpath"
331 direcive is found in .abs-file , XPath-indexing is disabled to ensure
332 backwards compatibility. For missing .abs-files XPath-indexing is
333 enabled so that such records are searchable.
335 Zebra warns about missing .abs-file only once (for each type).
337 Fixed a bug in file update where already-inserted files could
342 Zebra license changed to GNU GPL.
344 XPath-like queries used when RPN string attributes are used, eg.
345 @attr 1=/portal/title sometitle
346 @attr 1=/portal/title[@xml:lang=da] danishtitle
347 @attr 1=/portal/title/@xml:lang da
348 @attr 1=//title sometitle
350 Zebra uses UTF-8 internally:
351 1) New setting "encoding" for zebra.cfg that specifies encoding for
352 OCTET terms in queries and record encoding for most transfer syntaxes
353 (except those that use International Strings, such as GRS-1).
354 2) The encoding of International strings is UTF-8 by default. It
355 may be changed by character set negotiation. If character set
356 negotiation is in effect and if records are selected for conversion
357 these'll be converted to the selected character set - thus overriding
358 the encoding setting in zebra.cfg.
359 3) New directive "encoding" in .abs-files. This specifies the external
360 character encoding for files indexed by zebra. However, if records
361 themselves have an XML header that specifies and encoding that'll be used
364 XML filter (-t grs.xml).
366 Multiple registers. New setting in resource 'root' that holds base
367 directory for register(s). A group a databases may be put in separate
368 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
372 Fixes for Digital Unix
374 Implemented hits per term using USR:SearchResult-1.
376 New Zebra API. Locking system re-implemented.
378 --- 1.1.stable 2002/02/20
380 Rank weight can be controlled with attribute type 9. Default
381 value is 34. Recommended values between 1-36.
385 Updated for YAZ version 1.8.
387 Added support for termsets - a result set of terms matching
388 a given query. For @attr 8=<set> creates termset named <set>.
390 Added support for raw retrieval. Element Set Name R forces the
391 text filter which returns the record in its original form.
393 Added numerical sort - triggered by structure=numeric (4=109).
395 Remote record import using Z39.50 Extended Services and Segments.
397 Fixed bug where updating a database with user-defined attributes
398 could corrupt the register (bad storeKeys).
400 Multi-threaded version.
402 Fixed bug regarding proximity.
404 Documentation updates.
406 Fixed bug in record retrieval module that occured on 64-bit OSF
411 Fixed bug in makefile for WIN32.
413 Fixed bug in configure script - used bash-specific features.
417 Added support for multiple records in one file for filter grs.sgml.
419 Changed record index structure. New layout is incompatible with
420 previous releases. Added setting "recordcompression" to control
421 compression of records. Possible values are "none" (no
422 compression) and bzip2 (compression using libbz2).
424 Added XML transfer syntax support for retrieval of structured records.
425 Schema in CompSpec is recognised in retrieval of structured records.
427 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
428 that fails, the filter reads the file <filt>.flt (regx style filter).
430 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
431 Zebra's configure script automatically attempts to locate Tcl. For
432 manual Tcl configuration use option --with-tclconfig=<path> to specify
433 where Tcl's library files are located.
435 Implemented "compression" of Dictionary and ISAM system. Dictionary
438 Added "tagsysno" directive to zebra.cfg to control under which tag the
439 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
442 Added "tagrank" as above.
444 Changed file naming scheme for register files from <name>.mf.<no> to
447 Implemented "position"-flag for register type (as defined in
448 default.idx). When set to zero no position (or seqence number) is
449 saved in register for each word occurrence, thus saving some register
452 Implemented database mapping. Using mapdb one can specify a database
453 to be mapped to one or more physical databases. Usage:
454 mapdb <fromdb> <todb> ..
456 Added SOIF-filter. Thanks to Peter Valkenburg.
458 For the regx-filter "end element -record" may trigger a mark-of-record
459 if outer level is reached.
461 Tag sets may be typed in the reference to it. From the .abs-file the
462 "tagset" directive takes a third optional integer type for the tag set
463 referenced. From a .tag-file the "include" directive takes a third
464 optional type as well. The old "type" directive in the tag set itself
465 is still recognized but acts as the default type for the tag set.
467 Zebra supports the specification of arbitrary attributes sets, schemas
468 and tag sets, because of the change in YAZ' OID management system.
470 Fixed bug in Sort that caused it NOT to use character mapping as it
473 Zebra now uses GNU configure to generate Makefile(s).
475 Added un-optimised support for left and left/right truncation attributes.
477 Added support for relational operators on text when using RPN queries.
479 Added support for sort specifications in RPN queries. Type 7 specifies
480 'sort' where value 1=ascending, value 2=descending. The use attribute
481 specifies the field criteria as usual. The term specifies priority
482 where 0=first, 1=second, ...
484 Changed the way use attributes are specified in the recordId
487 Maximum number of databases in one Zebra register increased.
489 New setting, databasePath, which specifies that first directory during
490 update traversal is the database name (instead of a fixed one).
492 New setting, explainDatabase, which specifies that databases are
495 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
497 Implemented EXPLAIN database maintenance. Zebra automatically
498 generate - and update CategoryList, TargetInfo, DatabaseInfo,
499 AttributeSetInfo and AttributeDetails records at this stage. The
500 records may be transferred as GRS-1, SUTRS or Explain.
502 Fixed register spec so that colon isn't treated as size separator
503 unless followed by [0-9+-] in order to allow DOS drive specifications.
505 Fixed two bugs in ISAMC system.
507 Changed the way Zebra keeps its maintenance information about attribute
508 sets, available attributes, etc.. Records in "SGML" notation using an
509 EXPLAIN schema is now used when appropriate.
511 Bug fix: Index didn't handle update/insert/delete of the same record
512 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
513 first occurence of a record is considered.
515 Most searches now return correct number of hits.
517 New modular ranking system. Interested programmers are encouraged to
518 inspect rank1.c and improve the algorithm.
520 Bug fix: Lock files weren't removed as they should on NT.
522 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
523 specify a "sort register". Refer to the gils sample records which refer
524 to index type "s" which is specified as "sort" in the default.idx file.
525 Each sort criteria can either be Ascending or Descending and at most
526 three sort elements can be specified.
528 Bug fix: Character mapping didn't work for text files.
532 Simple ranked searches now return correct number of hits.
534 The test option (-s) only makes a read-lock on the index as well
535 as using read-only operations anywhere.
537 Moved towards generic character mapping. Configuration file default.idx
538 specifies character map files for register types w, p, u, etc.
540 Implemented "begin variant" for the sgml.regx - filter.
542 Fixed a few memory leaks.
544 Added support for C++, headers uses extern "C" for public definitions.
546 Bug fix: The show records facility (-s) only displayed information for
547 the first record in a file (and not for every record in the file).
549 Added option "-f <n>" to limit the logging of record operations. After
550 <n> records has been processed no logging is performed (unless errors
553 Bug fix: the compressed ISAM system didn't handle update operations
556 Added setting, "maxResultSetSize", to hold the number of records to
557 save in a result set.
559 Bug fix: Complete phrase did't work for search operations.
561 Bug fix: temporary result sets weren't deleted.
563 Reduced disk space for saved keys (storeKeys = 1).
565 Added optional, physical ANY (key replication)
567 Implemented proximity operator in search.
569 Bug fix: the path name buffers used by file match traversal routines
570 have been extended to support long file names.
572 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
573 configuration file. The resulting register without "storeKeys" is about
574 half the size, and the memory used by zebraidx during phase 2 (merge) is
575 reduced to a minimum.
577 Reworked the way Regexp-2 queries with error tolerance are handled and
578 specified. The documentation has been updated accordingly.
580 Bug fix: Zebrasrv didn't search correctly when queries contained masking
581 characters. This bug was introduced in 1.0a8.
583 Zebrasrv now tag records with the proper database name.
585 New settings, memMax and keyTmpDir.
587 Changed name of setting lockDir (previously called lockPath) and
588 setTmpDir (previously called tempSetPath).
590 Generalized and changed record type specifications. In short, there are:
592 grs.sgml structured, "SGML-like" syntax
593 grs.regx.<filter> structured, Regular expression filter
594 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
595 is the name of an abstract syntax file.
596 Bug fix: Result sets weren't sorted in operations involving boolean
597 operations with "ranked" operands.
601 Added national character-handling subsystem.
605 Small modifications to input filters and profiles.
607 Added support for SOIF syntax (with private OID).
611 Fixed buffer-size problem in indexing.
613 Added compression to temporary files for updating.
615 Added phrase registers.
617 Added dynamic mapping of search attribute to multiple termlists (ANY).
619 Scan support in multiple databases/registers.
621 Configuration settings are case-insensitive and single dash (-)
622 characters are ignored in comparisons.
624 The index processing ignores empty files - warning given.
626 New option to zebraidx (-V) displays version information.
630 Fixed problem in file-update system.
632 Fixed problem in shadow system; register was sometimes corrupted after
637 Fixed problems in the ISAM subsystem. Caused difficulties when updating
640 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
641 the rank and record number.
643 Fixed bug in the isam subsystem - caused a malfunction when accessing
644 words which occurred more than 10000 times.
646 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
649 Server can now run under inetd. Use option -i, and -w <directory> to
650 set working directory to desired location.
652 New zebraidx command: clean - removes temporary shadow files.
654 Fixed bug in ISAM system. Occurred rarely during register updates.
656 Logging during index merge phase is improved. The remaining running
659 Temporary files generated by zebraidx are removed after each run.
661 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
662 when doing scan operations in dictionaries with European characters.
666 A whole slew of updates, to make the first publicized release. Get the doc
671 Memory-problems in ISAM fixed. More blocktypes added to the default setup
672 to increase performance on larger databases.
674 Various minor changes in data management system.
678 A couple of portability-problems resolved.
680 Changed some malloc() to xmalloc().
