1 Added 'melm' directive to absyn format to simplify config files
2 for MARC-style databases. See tab/marc21.abs for an example.
4 Added support for special slement set _sysno_ which returns a
5 record ID for a record packed as a SUTRS record.
9 Documented authentication facility in Zebra. Added zebra.cfg directive
10 'passwd.c' which specifies user accounts file with encrypted passwords. The
11 directive 'passwd' specifies user accounts file with clear-text passwords.
12 The previous version of Zebra used plain/clear text depending on
13 configuration automatically. That caused upgrade trouble. Bug #356.
17 Depend on YAZ 2.0.18 or later in configure.
19 Fixed crash that could occur if ES update transaction failed.
21 Configure enables the use of the crypt API - if available.

41 Fixed bug #253: Setting group.database not honored
43 Fixed bug #252: Sort does not work.
45 Fixed bug #248: hit counts in combinatoric (and) searches in specific ..
49 Fixed bug #248: hit counts in combinatoric (and) searches in specific ..
51 Fixed bug #245: Time for getting records changes a lot based on record
54 Fixed bug #235: weird x-path results.
56 Avoid crash in ISAMB when isamb_pp_open gets ISAMB_POS = 0. In
57 this case EOF (no entries) is signalled. It fixes problem with
58 terms being deleted. See bug #109.
60 Fixed bug #169: Phrase term counts does not work. The bug exists in
63 Added mechanism to ignore leading articles when doing full-field indexing,
64 based on the character map files. See the manual for further discussion.
68 Fixed bug in record management. Releasing blocks could result in
71 Fixed bug in isam:b. A tree split could result in a lost item.
75 Add IDZebra.i to dist so that Perl extension builds again.
79 Added facility to make attibutes in grs.regx and grs.tcl filter using the
80 data command with argument -attribute <name> . The content of data is
81 the value of the attribute. This command should be used inside a
82 begin element , end element section.
84 Update zebra.nsi to NSIS 2.
86 Added a new 'cut' directive to charmaps (.chr files) which specifies that
87 only characters after the cutting char should be indexed.
89 Update Perl internals so that it matches the current Zebra API.
90 The recordGroup structure is no longer available. A group of resources
91 can still be referenced by setting groupName=>.. in various methods.
93 Maximum number of records to be sorted in a result set can be
94 specified by setting "sortmax". Default is 1000.
96 Allow use of string use attributes for regular attribute sets. The
97 name matches the name given in the attribute set file. All strings
98 starting with / are considered X-Path as usual.
100 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
101 element for XML tree. It may only pop off if -record is given.
103 Added grs.danbib filter - for Danish Bibliographic Centre.
105 Rename CHANGELOG to NEWS.
107 For text filter, return only header if elementSetName=H . elementSetName=R
108 returns contents only. Other elementSetName returns both header+content.
110 Added test for charmap and rusmarc.
112 Added feature charmaps (.chr) so that characters may be specified in
115 Fixed problem with encoding directive for charmap(.chr) files.
117 Allow Remote insert/delete/replace/update with record, recordIdNumber
118 (sysno) and/or recordIdOpaque(user supplied record Id). If both
119 IDs are omitted internal record ID match is assumed (recordId: - in
122 --- 1.3.15 2004/01/15

134 --- 1.3.13 2003/09/26
136 Add missing examples for Windows install.
138 Fix bug in regx filter to make it "greedy" again. This bug appeared
143 --- 1.3.12 2003/09/08
145 Fix XML error handling. Stop XML parse immediately if XML parse error
146 occur (i.e. produce one error only).
148 Zebra ignores "unsupported use attribute" for individual databases
149 when search multiple databases (unless all databases fail).
151 New filter grs.marcxml which works like grs.marc but produces MARCXML.
153 Added support for database deletion. It is possible to create/drop
154 a database from zebraidx utility. Note: only for isam:b.
156 Write zebrasrv.pid to lockdir.
158 Bug fix: result sets were not recovered correctly. Had to
159 add ODR handle for zebra_search_RPN in order to make it work.
161 Fixed a bug in regx filters that didn't do anchors (^) correctly.
163 Fixed a bug in searches with X-Path searches sometimes giving "extra"
166 Zebra server checks for zebrasrv.pid and refuses to start if it is already
167 locked by another (running) zebrasrv.
169 Fixed a bug with text being chunked in pieces for the grs.xml filter.
171 --- 1.3.11 2003/04/25
173 xelm code updates. xelm works regardless state of 'xpath enable/disable'
174 Avoid -L/usr/lib since that is already default library path.
176 Allow multiple updates within one transaction.
178 Fixed a bug with >2GB files (overflow in integer expression).
180 --- 1.3.10 2003/04/01
182 Fix linker error for Perl module.
184 Fix bug in and operation which in some cases could result in "extra"
185 hits. Bug was introduced in 1.3.5.
187 Fix bug in handling of schema conversion when producing numeric tags.
193 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
197 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
198 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
199 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
201 livrank: another experimental ranking algorithm. Source in livcode.c.
202 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
204 Contributed by Pete Mallinson, University of Liverpool.
206 Advanced MARC indexing. See doc/marc_indexing.xml
207 Oleg Kolobov <oleg at lib.tpu.ru>
209 Perl API updates and fixes.
210 Peter Popovics <pop at technomat.hu>
212 Fixed 'zebraidx delete'.
214 Implemented 'zebraidx clean'.
216 64-bit offsets for register files on WIN32 (no 2 GB limit).
218 Fixed a few memory leaks WRT sorting.
222 Fixed error handling : error code was not properly returned.
224 Support Truncation 104 (CCL).
228 Added missing source files for perl extension.
232 Implemented xelm directive.
234 Updated for newer version of YAZ (introduction of string schema).
236 Directory examples/zthes now part of distribution (was missing
237 in previous release).
239 New .abs directive, systag, that control where to put retrieval
240 information. The directive takes two arguments: system tag, element name.
241 System tag is one of : rank, sysno, size.
245 Perl Filter and Perl API. By Peter Popovics.
247 For zebra.cfg, if no profilePath is specified, directory
248 (prefix)/share/idzebra/tab
251 Zebra Examples in examples . Zebra tests in test.
253 Bug fix: sort index was not properly modified on
254 record updates/deletes.
256 Fix handling of character entities for sgml filter.
258 Move data1 to Zebra (used to be part of YAZ).
262 Fix character encoding of scan response terms.
264 Fix character decoding of scan request terms.
266 Fix ESpec handling (requires YAZ 1.9.1)
268 Fix searches for complete fields.
272 When name zebra is used in a filename or directory 'idzebra' is used
273 instead to avoid confusion with GNU zebra (routing software).
275 Zebra server stops with a fatal error if config file cannot be read.
277 New config setting, followLinks, that controls whether update of files
278 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
279 By default symbolic links are followed.
281 Fix MARC transfer . MARC fields had wrong data for multiple fields.
283 XML record reader moved from YAZ to Zebra, to make YAZ less
284 dependant on external libraries.
286 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
287 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
288 on systems that doesn't offer iconv.
290 XML record reader supports external system entities.
294 New .abs-directive "xpath" that takes one argument: "enable"
295 or "disable" to enable and disable XPath -indexing. If no "xpath"
296 direcive is found in .abs-file , XPath-indexing is disabled to ensure
297 backwards compatibility. For missing .abs-files XPath-indexing is
298 enabled so that such records are searchable.
300 Zebra warns about missing .abs-file only once (for each type).
302 Fixed a bug in file update where already-inserted files could
307 Zebra license changed to GNU GPL.
309 XPath-like queries used when RPN string attributes are used, eg.
310 @attr 1=/portal/title sometitle
311 @attr 1=/portal/title[@xml:lang=da] danishtitle
312 @attr 1=/portal/title/@xml:lang da
313 @attr 1=//title sometitle
315 Zebra uses UTF-8 internally:
316 1) New setting "encoding" for zebra.cfg that specifies encoding for
317 OCTET terms in queries and record encoding for most transfer syntaxes
318 (except those that use International Strings, such as GRS-1).
319 2) The encoding of International strings is UTF-8 by default. It
320 may be changed by character set negotiation. If character set
321 negotiation is in effect and if records are selected for conversion
322 these'll be converted to the selected character set - thus overriding
323 the encoding setting in zebra.cfg.
324 3) New directive "encoding" in .abs-files. This specifies the external
325 character encoding for files indexed by zebra. However, if records
326 themselves have an XML header that specifies and encoding that'll be used
329 XML filter (-t grs.xml).
331 Multiple registers. New setting in resource 'root' that holds base
332 directory for register(s). A group a databases may be put in separate
333 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
337 Fixes for Digital Unix
339 Implemented hits per term using USR:SearchResult-1.
341 New Zebra API. Locking system re-implemented.
343 --- 1.1.stable 2002/02/20
345 Rank weight can be controlled with attribute type 9. Default
346 value is 34. Recommended values between 1-36.
350 Updated for YAZ version 1.8.
352 Added support for termsets - a result set of terms matching
353 a given query. For @attr 8=<set> creates termset named <set>.
355 Added support for raw retrieval. Element Set Name R forces the
356 text filter which returns the record in its original form.
358 Added numerical sort - triggered by structure=numeric (4=109).
360 Remote record import using Z39.50 Extended Services and Segments.
362 Fixed bug where updating a database with user-defined attributes
363 could corrupt the register (bad storeKeys).
365 Multi-threaded version.
367 Fixed bug regarding proximity.
369 Documentation updates.
371 Fixed bug in record retrieval module that occured on 64-bit OSF
376 Fixed bug in makefile for WIN32.
378 Fixed bug in configure script - used bash-specific features.
382 Added support for multiple records in one file for filter grs.sgml.
384 Changed record index structure. New layout is incompatible with
385 previous releases. Added setting "recordcompression" to control
386 compression of records. Possible values are "none" (no
387 compression) and bzip2 (compression using libbz2).
389 Added XML transfer syntax support for retrieval of structured records.
390 Schema in CompSpec is recognised in retrieval of structured records.
392 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
393 that fails, the filter reads the file <filt>.flt (regx style filter).
395 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
396 Zebra's configure script automatically attempts to locate Tcl. For
397 manual Tcl configuration use option --with-tclconfig=<path> to specify
398 where Tcl's library files are located.
400 Implemented "compression" of Dictionary and ISAM system. Dictionary
403 Added "tagsysno" directive to zebra.cfg to control under which tag the
404 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
407 Added "tagrank" as above.
409 Changed file naming scheme for register files from <name>.mf.<no> to
412 Implemented "position"-flag for register type (as defined in
413 default.idx). When set to zero no position (or seqence number) is
414 saved in register for each word occurrence, thus saving some register
417 Implemented database mapping. Using mapdb one can specify a database
418 to be mapped to one or more physical databases. Usage:
419 mapdb <fromdb> <todb> ..
421 Added SOIF-filter. Thanks to Peter Valkenburg.
423 For the regx-filter "end element -record" may trigger a mark-of-record
424 if outer level is reached.
426 Tag sets may be typed in the reference to it. From the .abs-file the
427 "tagset" directive takes a third optional integer type for the tag set
428 referenced. From a .tag-file the "include" directive takes a third
429 optional type as well. The old "type" directive in the tag set itself
430 is still recognized but acts as the default type for the tag set.
432 Zebra supports the specification of arbitrary attributes sets, schemas
433 and tag sets, because of the change in YAZ' OID management system.
435 Fixed bug in Sort that caused it NOT to use character mapping as it
438 Zebra now uses GNU configure to generate Makefile(s).
440 Added un-optimised support for left and left/right truncation attributes.
442 Added support for relational operators on text when using RPN queries.
444 Added support for sort specifications in RPN queries. Type 7 specifies
445 'sort' where value 1=ascending, value 2=descending. The use attribute
446 specifies the field criteria as usual. The term specifies priority
447 where 0=first, 1=second, ...
449 Changed the way use attributes are specified in the recordId
452 Maximum number of databases in one Zebra register increased.
454 New setting, databasePath, which specifies that first directory during
455 update traversal is the database name (instead of a fixed one).
457 New setting, explainDatabase, which specifies that databases are
460 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
462 Implemented EXPLAIN database maintenance. Zebra automatically
463 generate - and update CategoryList, TargetInfo, DatabaseInfo,
464 AttributeSetInfo and AttributeDetails records at this stage. The
465 records may be transferred as GRS-1, SUTRS or Explain.
467 Fixed register spec so that colon isn't treated as size separator
468 unless followed by [0-9+-] in order to allow DOS drive specifications.
470 Fixed two bugs in ISAMC system.
472 Changed the way Zebra keeps its maintenance information about attribute
473 sets, available attributes, etc.. Records in "SGML" notation using an
474 EXPLAIN schema is now used when appropriate.
476 Bug fix: Index didn't handle update/insert/delete of the same record
477 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
478 first occurence of a record is considered.
480 Most searches now return correct number of hits.
482 New modular ranking system. Interested programmers are encouraged to
483 inspect rank1.c and improve the algorithm.
485 Bug fix: Lock files weren't removed as they should on NT.
487 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
488 specify a "sort register". Refer to the gils sample records which refer
489 to index type "s" which is specified as "sort" in the default.idx file.
490 Each sort criteria can either be Ascending or Descending and at most
491 three sort elements can be specified.
493 Bug fix: Character mapping didn't work for text files.
497 Simple ranked searches now return correct number of hits.
499 The test option (-s) only makes a read-lock on the index as well
500 as using read-only operations anywhere.
502 Moved towards generic character mapping. Configuration file default.idx
503 specifies character map files for register types w, p, u, etc.
505 Implemented "begin variant" for the sgml.regx - filter.
507 Fixed a few memory leaks.
509 Added support for C++, headers uses extern "C" for public definitions.
511 Bug fix: The show records facility (-s) only displayed information for
512 the first record in a file (and not for every record in the file).
514 Added option "-f <n>" to limit the logging of record operations. After
515 <n> records has been processed no logging is performed (unless errors
518 Bug fix: the compressed ISAM system didn't handle update operations
521 Added setting, "maxResultSetSize", to hold the number of records to
522 save in a result set.
524 Bug fix: Complete phrase did't work for search operations.
526 Bug fix: temporary result sets weren't deleted.
528 Reduced disk space for saved keys (storeKeys = 1).
530 Added optional, physical ANY (key replication)
532 Implemented proximity operator in search.
534 Bug fix: the path name buffers used by file match traversal routines
535 have been extended to support long file names.
537 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
538 configuration file. The resulting register without "storeKeys" is about
539 half the size, and the memory used by zebraidx during phase 2 (merge) is
540 reduced to a minimum.
542 Reworked the way Regexp-2 queries with error tolerance are handled and
543 specified. The documentation has been updated accordingly.
545 Bug fix: Zebrasrv didn't search correctly when queries contained masking
546 characters. This bug was introduced in 1.0a8.
548 Zebrasrv now tag records with the proper database name.
550 New settings, memMax and keyTmpDir.
552 Changed name of setting lockDir (previously called lockPath) and
553 setTmpDir (previously called tempSetPath).
555 Generalized and changed record type specifications. In short, there are:
557 grs.sgml structured, "SGML-like" syntax
558 grs.regx.<filter> structured, Regular expression filter
559 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
560 is the name of an abstract syntax file.
561 Bug fix: Result sets weren't sorted in operations involving boolean
562 operations with "ranked" operands.
566 Added national character-handling subsystem.
570 Small modifications to input filters and profiles.
572 Added support for SOIF syntax (with private OID).
576 Fixed buffer-size problem in indexing.
578 Added compression to temporary files for updating.
580 Added phrase registers.
582 Added dynamic mapping of search attribute to multiple termlists (ANY).
584 Scan support in multiple databases/registers.
586 Configuration settings are case-insensitive and single dash (-)
587 characters are ignored in comparisons.
589 The index processing ignores empty files - warning given.
591 New option to zebraidx (-V) displays version information.
595 Fixed problem in file-update system.
597 Fixed problem in shadow system; register was sometimes corrupted after
602 Fixed problems in the ISAM subsystem. Caused difficulties when updating
605 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
606 the rank and record number.
608 Fixed bug in the isam subsystem - caused a malfunction when accessing
609 words which occurred more than 10000 times.
611 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
614 Server can now run under inetd. Use option -i, and -w <directory> to
615 set working directory to desired location.
617 New zebraidx command: clean - removes temporary shadow files.
619 Fixed bug in ISAM system. Occurred rarely during register updates.
621 Logging during index merge phase is improved. The remaining running
624 Temporary files generated by zebraidx are removed after each run.
626 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
627 when doing scan operations in dictionaries with European characters.
631 A whole slew of updates, to make the first publicized release. Get the doc
636 Memory-problems in ISAM fixed. More blocktypes added to the default setup
637 to increase performance on larger databases.
639 Various minor changes in data management system.
643 A couple of portability-problems resolved.
645 Changed some malloc() to xmalloc().
