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

41 Fix X-Path attribute indexing. Bug #431.
45 Fixed bug #415: Strange truncation behavior.
47 Added 'melm' directive to absyn format to simplify config files
48 for MARC-style databases. See tab/marc21.abs for an example.
50 Added support for special slement set _sysno_ which returns a
51 record ID for a record packed as a SUTRS record.
55 Documented authentication facility in Zebra. Added zebra.cfg directive
56 'passwd.c' which specifies user accounts file with encrypted passwords. The
57 directive 'passwd' specifies user accounts file with clear-text passwords.
58 The previous version of Zebra used plain/clear text depending on
59 configuration automatically. That caused upgrade trouble. Bug #356.
63 Depend on YAZ 2.0.18 or later in configure.
65 Fixed crash that could occur if ES update transaction failed.
67 Configure enables the use of the crypt API - if available.
69 Fixed bug #304: Fuzzy search regExpr-2 did not use proper error distance
72 Fixed bug #305: Scan now handles negative preferred-position-in-response.
74 Implemented the 'equivalent' directive for .chr-files.
78 For configure, support threading again. It was removed by mistake
81 Fixed bug #262: spaces in control fields in MARC returned.

98 Fixed bug #235: weird x-path results.
100 Avoid crash in ISAMB when isamb_pp_open gets ISAMB_POS = 0. In
101 this case EOF (no entries) is signalled. It fixes problem with
102 terms being deleted. See bug #109.
104 Fixed bug #169: Phrase term counts does not work. The bug exists in
107 Added mechanism to ignore leading articles when doing full-field indexing,
108 based on the character map files. See the manual for further discussion.
110 --- 1.3.18 2004/08/20
112 Fixed bug in record management. Releasing blocks could result in
115 Fixed bug in isam:b. A tree split could result in a lost item.
117 --- 1.3.17 2004/08/17
119 Add IDZebra.i to dist so that Perl extension builds again.
121 --- 1.3.16 2004/08/16
123 Added facility to make attibutes in grs.regx and grs.tcl filter using the
124 data command with argument -attribute <name> . The content of data is
125 the value of the attribute. This command should be used inside a
126 begin element , end element section.
128 Update zebra.nsi to NSIS 2.
130 Added a new 'cut' directive to charmaps (.chr files) which specifies that
131 only characters after the cutting char should be indexed.
133 Update Perl internals so that it matches the current Zebra API.
134 The recordGroup structure is no longer available. A group of resources
135 can still be referenced by setting groupName=>.. in various methods.
137 Maximum number of records to be sorted in a result set can be
138 specified by setting "sortmax". Default is 1000.
140 Allow use of string use attributes for regular attribute sets. The
141 name matches the name given in the attribute set file. All strings
142 starting with / are considered X-Path as usual.
144 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
145 element for XML tree. It may only pop off if -record is given.
147 Added grs.danbib filter - for Danish Bibliographic Centre.
149 Rename CHANGELOG to NEWS.
151 For text filter, return only header if elementSetName=H . elementSetName=R
152 returns contents only. Other elementSetName returns both header+content.
154 Added test for charmap and rusmarc.
156 Added feature charmaps (.chr) so that characters may be specified in
159 Fixed problem with encoding directive for charmap(.chr) files.
161 Allow Remote insert/delete/replace/update with record, recordIdNumber
162 (sysno) and/or recordIdOpaque(user supplied record Id). If both
163 IDs are omitted internal record ID match is assumed (recordId: - in
166 --- 1.3.15 2004/01/15

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