1 Fixed bug #47: Commit needs to check for roll-back.
3 Fixed bug #672: Trailing characters in password are ignored
5 Added extra presence check for tcl.h, because some systems have
6 tclConfig.sh installed even though Tcl C headers are missing.
10 Optimized melm performance.
12 Do not use sync(2) during commit (but rely on sync'd individual files).
16 Updated Debian package to use sym links for zebraidx, zebrasrv.
18 Fixed bug in isamb (isam:b) regarding ISAM tree splitting.
20 Fixed problem with file locking during commit phase. This error was

26 of 0, gets incorrect term count
28 Fixed bug #597: Support null missing key for sort.
32 Fixed bug #465: dup fields in ISO2709 retrieval.
34 Another fix for X-Path indexing. The previous fix, unfortunately, indexed
39 Fix X-Path attribute indexing. Bug #431.
43 Fixed bug #415: Strange truncation behavior.
45 Added 'melm' directive to absyn format to simplify config files
46 for MARC-style databases. See tab/marc21.abs for an example.
48 Added support for special slement set _sysno_ which returns a
49 record ID for a record packed as a SUTRS record.
53 Documented authentication facility in Zebra. Added zebra.cfg directive
54 'passwd.c' which specifies user accounts file with encrypted passwords. The
55 directive 'passwd' specifies user accounts file with clear-text passwords.
56 The previous version of Zebra used plain/clear text depending on
57 configuration automatically. That caused upgrade trouble. Bug #356.
61 Depend on YAZ 2.0.18 or later in configure.
63 Fixed crash that could occur if ES update transaction failed.
65 Configure enables the use of the crypt API - if available.
67 Fixed bug #304: Fuzzy search regExpr-2 did not use proper error distance
70 Fixed bug #305: Scan now handles negative preferred-position-in-response.
72 Implemented the 'equivalent' directive for .chr-files.
76 For configure, support threading again. It was removed by mistake
79 Fixed bug #262: spaces in control fields in MARC returned.

93 Fixed bug #245: Time for getting records changes a lot based on record
96 Fixed bug #235: weird x-path results.
98 Avoid crash in ISAMB when isamb_pp_open gets ISAMB_POS = 0. In
99 this case EOF (no entries) is signalled. It fixes problem with
100 terms being deleted. See bug #109.
102 Fixed bug #169: Phrase term counts does not work. The bug exists in
105 Added mechanism to ignore leading articles when doing full-field indexing,
106 based on the character map files. See the manual for further discussion.
108 --- 1.3.18 2004/08/20
110 Fixed bug in record management. Releasing blocks could result in
113 Fixed bug in isam:b. A tree split could result in a lost item.
115 --- 1.3.17 2004/08/17
117 Add IDZebra.i to dist so that Perl extension builds again.
119 --- 1.3.16 2004/08/16
121 Added facility to make attibutes in grs.regx and grs.tcl filter using the
122 data command with argument -attribute <name> . The content of data is
123 the value of the attribute. This command should be used inside a
124 begin element , end element section.
126 Update zebra.nsi to NSIS 2.
128 Added a new 'cut' directive to charmaps (.chr files) which specifies that
129 only characters after the cutting char should be indexed.
131 Update Perl internals so that it matches the current Zebra API.
132 The recordGroup structure is no longer available. A group of resources
133 can still be referenced by setting groupName=>.. in various methods.
135 Maximum number of records to be sorted in a result set can be
136 specified by setting "sortmax". Default is 1000.
138 Allow use of string use attributes for regular attribute sets. The
139 name matches the name given in the attribute set file. All strings
140 starting with / are considered X-Path as usual.
142 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
143 element for XML tree. It may only pop off if -record is given.
145 Added grs.danbib filter - for Danish Bibliographic Centre.
147 Rename CHANGELOG to NEWS.
149 For text filter, return only header if elementSetName=H . elementSetName=R
150 returns contents only. Other elementSetName returns both header+content.
152 Added test for charmap and rusmarc.
154 Added feature charmaps (.chr) so that characters may be specified in
157 Fixed problem with encoding directive for charmap(.chr) files.
159 Allow Remote insert/delete/replace/update with record, recordIdNumber
160 (sysno) and/or recordIdOpaque(user supplied record Id). If both
161 IDs are omitted internal record ID match is assumed (recordId: - in
164 --- 1.3.15 2004/01/15

170 --- 1.3.14 2003/11/29
172 Fix bug with shadow and result set handling.
174 Implement MARCXML to ISO2709 conversion.
176 --- 1.3.13 2003/09/26
178 Add missing examples for Windows install.
180 Fix bug in regx filter to make it "greedy" again. This bug appeared
185 --- 1.3.12 2003/09/08
187 Fix XML error handling. Stop XML parse immediately if XML parse error
188 occur (i.e. produce one error only).
190 Zebra ignores "unsupported use attribute" for individual databases
191 when search multiple databases (unless all databases fail).
193 New filter grs.marcxml which works like grs.marc but produces MARCXML.
195 Added support for database deletion. It is possible to create/drop
196 a database from zebraidx utility. Note: only for isam:b.
198 Write zebrasrv.pid to lockdir.
200 Bug fix: result sets were not recovered correctly. Had to
201 add ODR handle for zebra_search_RPN in order to make it work.
203 Fixed a bug in regx filters that didn't do anchors (^) correctly.
205 Fixed a bug in searches with X-Path searches sometimes giving "extra"
208 Zebra server checks for zebrasrv.pid and refuses to start if it is already
209 locked by another (running) zebrasrv.
211 Fixed a bug with text being chunked in pieces for the grs.xml filter.
213 --- 1.3.11 2003/04/25
215 xelm code updates. xelm works regardless state of 'xpath enable/disable'
216 Avoid -L/usr/lib since that is already default library path.
218 Allow multiple updates within one transaction.
220 Fixed a bug with >2GB files (overflow in integer expression).
222 --- 1.3.10 2003/04/01
224 Fix linker error for Perl module.
226 Fix bug in and operation which in some cases could result in "extra"
227 hits. Bug was introduced in 1.3.5.
229 Fix bug in handling of schema conversion when producing numeric tags.
235 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
239 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
240 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
241 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
243 livrank: another experimental ranking algorithm. Source in livcode.c.
244 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
246 Contributed by Pete Mallinson, University of Liverpool.
248 Advanced MARC indexing. See doc/marc_indexing.xml
249 Oleg Kolobov <oleg at lib.tpu.ru>
251 Perl API updates and fixes.
252 Peter Popovics <pop at technomat.hu>
254 Fixed 'zebraidx delete'.
256 Implemented 'zebraidx clean'.
258 64-bit offsets for register files on WIN32 (no 2 GB limit).
260 Fixed a few memory leaks WRT sorting.
264 Fixed error handling : error code was not properly returned.
266 Support Truncation 104 (CCL).
270 Added missing source files for perl extension.
274 Implemented xelm directive.
276 Updated for newer version of YAZ (introduction of string schema).
278 Directory examples/zthes now part of distribution (was missing
279 in previous release).
281 New .abs directive, systag, that control where to put retrieval
282 information. The directive takes two arguments: system tag, element name.
283 System tag is one of : rank, sysno, size.
287 Perl Filter and Perl API. By Peter Popovics.
289 For zebra.cfg, if no profilePath is specified, directory
290 (prefix)/share/idzebra/tab
293 Zebra Examples in examples . Zebra tests in test.
295 Bug fix: sort index was not properly modified on
296 record updates/deletes.
298 Fix handling of character entities for sgml filter.
300 Move data1 to Zebra (used to be part of YAZ).
304 Fix character encoding of scan response terms.
306 Fix character decoding of scan request terms.
308 Fix ESpec handling (requires YAZ 1.9.1)
310 Fix searches for complete fields.
314 When name zebra is used in a filename or directory 'idzebra' is used
315 instead to avoid confusion with GNU zebra (routing software).
317 Zebra server stops with a fatal error if config file cannot be read.
319 New config setting, followLinks, that controls whether update of files
320 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
321 By default symbolic links are followed.
323 Fix MARC transfer . MARC fields had wrong data for multiple fields.
325 XML record reader moved from YAZ to Zebra, to make YAZ less
326 dependant on external libraries.
328 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
329 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
330 on systems that doesn't offer iconv.
332 XML record reader supports external system entities.
336 New .abs-directive "xpath" that takes one argument: "enable"
337 or "disable" to enable and disable XPath -indexing. If no "xpath"
338 direcive is found in .abs-file , XPath-indexing is disabled to ensure
339 backwards compatibility. For missing .abs-files XPath-indexing is
340 enabled so that such records are searchable.
342 Zebra warns about missing .abs-file only once (for each type).
344 Fixed a bug in file update where already-inserted files could
349 Zebra license changed to GNU GPL.
351 XPath-like queries used when RPN string attributes are used, eg.
352 @attr 1=/portal/title sometitle
353 @attr 1=/portal/title[@xml:lang=da] danishtitle
354 @attr 1=/portal/title/@xml:lang da
355 @attr 1=//title sometitle
357 Zebra uses UTF-8 internally:
358 1) New setting "encoding" for zebra.cfg that specifies encoding for
359 OCTET terms in queries and record encoding for most transfer syntaxes
360 (except those that use International Strings, such as GRS-1).
361 2) The encoding of International strings is UTF-8 by default. It
362 may be changed by character set negotiation. If character set
363 negotiation is in effect and if records are selected for conversion
364 these'll be converted to the selected character set - thus overriding
365 the encoding setting in zebra.cfg.
366 3) New directive "encoding" in .abs-files. This specifies the external
367 character encoding for files indexed by zebra. However, if records
368 themselves have an XML header that specifies and encoding that'll be used
371 XML filter (-t grs.xml).
373 Multiple registers. New setting in resource 'root' that holds base
374 directory for register(s). A group a databases may be put in separate
375 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
379 Fixes for Digital Unix
381 Implemented hits per term using USR:SearchResult-1.
383 New Zebra API. Locking system re-implemented.
385 --- 1.1.stable 2002/02/20
387 Rank weight can be controlled with attribute type 9. Default
388 value is 34. Recommended values between 1-36.
392 Updated for YAZ version 1.8.
394 Added support for termsets - a result set of terms matching
395 a given query. For @attr 8=<set> creates termset named <set>.
397 Added support for raw retrieval. Element Set Name R forces the
398 text filter which returns the record in its original form.
400 Added numerical sort - triggered by structure=numeric (4=109).
402 Remote record import using Z39.50 Extended Services and Segments.
404 Fixed bug where updating a database with user-defined attributes
405 could corrupt the register (bad storeKeys).
407 Multi-threaded version.
409 Fixed bug regarding proximity.
411 Documentation updates.
413 Fixed bug in record retrieval module that occured on 64-bit OSF
418 Fixed bug in makefile for WIN32.
420 Fixed bug in configure script - used bash-specific features.
424 Added support for multiple records in one file for filter grs.sgml.
426 Changed record index structure. New layout is incompatible with
427 previous releases. Added setting "recordcompression" to control
428 compression of records. Possible values are "none" (no
429 compression) and bzip2 (compression using libbz2).
431 Added XML transfer syntax support for retrieval of structured records.
432 Schema in CompSpec is recognised in retrieval of structured records.
434 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
435 that fails, the filter reads the file <filt>.flt (regx style filter).
437 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
438 Zebra's configure script automatically attempts to locate Tcl. For
439 manual Tcl configuration use option --with-tclconfig=<path> to specify
440 where Tcl's library files are located.
442 Implemented "compression" of Dictionary and ISAM system. Dictionary
445 Added "tagsysno" directive to zebra.cfg to control under which tag the
446 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
449 Added "tagrank" as above.
451 Changed file naming scheme for register files from <name>.mf.<no> to
454 Implemented "position"-flag for register type (as defined in
455 default.idx). When set to zero no position (or seqence number) is
456 saved in register for each word occurrence, thus saving some register
459 Implemented database mapping. Using mapdb one can specify a database
460 to be mapped to one or more physical databases. Usage:
461 mapdb <fromdb> <todb> ..
463 Added SOIF-filter. Thanks to Peter Valkenburg.
465 For the regx-filter "end element -record" may trigger a mark-of-record
466 if outer level is reached.
468 Tag sets may be typed in the reference to it. From the .abs-file the
469 "tagset" directive takes a third optional integer type for the tag set
470 referenced. From a .tag-file the "include" directive takes a third
471 optional type as well. The old "type" directive in the tag set itself
472 is still recognized but acts as the default type for the tag set.
474 Zebra supports the specification of arbitrary attributes sets, schemas
475 and tag sets, because of the change in YAZ' OID management system.
477 Fixed bug in Sort that caused it NOT to use character mapping as it
480 Zebra now uses GNU configure to generate Makefile(s).
482 Added un-optimised support for left and left/right truncation attributes.
484 Added support for relational operators on text when using RPN queries.
486 Added support for sort specifications in RPN queries. Type 7 specifies
487 'sort' where value 1=ascending, value 2=descending. The use attribute
488 specifies the field criteria as usual. The term specifies priority
489 where 0=first, 1=second, ...
491 Changed the way use attributes are specified in the recordId
494 Maximum number of databases in one Zebra register increased.
496 New setting, databasePath, which specifies that first directory during
497 update traversal is the database name (instead of a fixed one).
499 New setting, explainDatabase, which specifies that databases are
502 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
504 Implemented EXPLAIN database maintenance. Zebra automatically
505 generate - and update CategoryList, TargetInfo, DatabaseInfo,
506 AttributeSetInfo and AttributeDetails records at this stage. The
507 records may be transferred as GRS-1, SUTRS or Explain.
509 Fixed register spec so that colon isn't treated as size separator
510 unless followed by [0-9+-] in order to allow DOS drive specifications.
512 Fixed two bugs in ISAMC system.
514 Changed the way Zebra keeps its maintenance information about attribute
515 sets, available attributes, etc.. Records in "SGML" notation using an
516 EXPLAIN schema is now used when appropriate.
518 Bug fix: Index didn't handle update/insert/delete of the same record
519 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
520 first occurence of a record is considered.
522 Most searches now return correct number of hits.
524 New modular ranking system. Interested programmers are encouraged to
525 inspect rank1.c and improve the algorithm.
527 Bug fix: Lock files weren't removed as they should on NT.
529 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
530 specify a "sort register". Refer to the gils sample records which refer
531 to index type "s" which is specified as "sort" in the default.idx file.
532 Each sort criteria can either be Ascending or Descending and at most
533 three sort elements can be specified.
535 Bug fix: Character mapping didn't work for text files.
539 Simple ranked searches now return correct number of hits.
541 The test option (-s) only makes a read-lock on the index as well
542 as using read-only operations anywhere.
544 Moved towards generic character mapping. Configuration file default.idx
545 specifies character map files for register types w, p, u, etc.
547 Implemented "begin variant" for the sgml.regx - filter.
549 Fixed a few memory leaks.
551 Added support for C++, headers uses extern "C" for public definitions.
553 Bug fix: The show records facility (-s) only displayed information for
554 the first record in a file (and not for every record in the file).
556 Added option "-f <n>" to limit the logging of record operations. After
557 <n> records has been processed no logging is performed (unless errors
560 Bug fix: the compressed ISAM system didn't handle update operations
563 Added setting, "maxResultSetSize", to hold the number of records to
564 save in a result set.
566 Bug fix: Complete phrase did't work for search operations.
568 Bug fix: temporary result sets weren't deleted.
570 Reduced disk space for saved keys (storeKeys = 1).
572 Added optional, physical ANY (key replication)
574 Implemented proximity operator in search.
576 Bug fix: the path name buffers used by file match traversal routines
577 have been extended to support long file names.
579 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
580 configuration file. The resulting register without "storeKeys" is about
581 half the size, and the memory used by zebraidx during phase 2 (merge) is
582 reduced to a minimum.
584 Reworked the way Regexp-2 queries with error tolerance are handled and
585 specified. The documentation has been updated accordingly.
587 Bug fix: Zebrasrv didn't search correctly when queries contained masking
588 characters. This bug was introduced in 1.0a8.
590 Zebrasrv now tag records with the proper database name.
592 New settings, memMax and keyTmpDir.
594 Changed name of setting lockDir (previously called lockPath) and
595 setTmpDir (previously called tempSetPath).
597 Generalized and changed record type specifications. In short, there are:
599 grs.sgml structured, "SGML-like" syntax
600 grs.regx.<filter> structured, Regular expression filter
601 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
602 is the name of an abstract syntax file.
603 Bug fix: Result sets weren't sorted in operations involving boolean
604 operations with "ranked" operands.
608 Added national character-handling subsystem.
612 Small modifications to input filters and profiles.
614 Added support for SOIF syntax (with private OID).
618 Fixed buffer-size problem in indexing.
620 Added compression to temporary files for updating.
622 Added phrase registers.
624 Added dynamic mapping of search attribute to multiple termlists (ANY).
626 Scan support in multiple databases/registers.
628 Configuration settings are case-insensitive and single dash (-)
629 characters are ignored in comparisons.
631 The index processing ignores empty files - warning given.
633 New option to zebraidx (-V) displays version information.
637 Fixed problem in file-update system.
639 Fixed problem in shadow system; register was sometimes corrupted after
644 Fixed problems in the ISAM subsystem. Caused difficulties when updating
647 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
648 the rank and record number.
650 Fixed bug in the isam subsystem - caused a malfunction when accessing
651 words which occurred more than 10000 times.
653 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
656 Server can now run under inetd. Use option -i, and -w <directory> to
657 set working directory to desired location.
659 New zebraidx command: clean - removes temporary shadow files.
661 Fixed bug in ISAM system. Occurred rarely during register updates.
663 Logging during index merge phase is improved. The remaining running
666 Temporary files generated by zebraidx are removed after each run.
668 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
669 when doing scan operations in dictionaries with European characters.
673 A whole slew of updates, to make the first publicized release. Get the doc
678 Memory-problems in ISAM fixed. More blocktypes added to the default setup
679 to increase performance on larger databases.
681 Various minor changes in data management system.
685 A couple of portability-problems resolved.
687 Changed some malloc() to xmalloc().
