3 Fixed bug #465: dup fields in ISO2709 retrieval.
5 Another fix for X-Path indexing. The previous fix, unfortunately, indexed
10 Fix X-Path attribute indexing. Bug #431.
14 Fixed bug #415: Strange truncation behavior.
16 Added 'melm' directive to absyn format to simplify config files
17 for MARC-style databases. See tab/marc21.abs for an example.
19 Added support for special slement set _sysno_ which returns a
20 record ID for a record packed as a SUTRS record.
24 Documented authentication facility in Zebra. Added zebra.cfg directive
25 'passwd.c' which specifies user accounts file with encrypted passwords. The
26 directive 'passwd' specifies user accounts file with clear-text passwords.
27 The previous version of Zebra used plain/clear text depending on
28 configuration automatically. That caused upgrade trouble. Bug #356.
32 Depend on YAZ 2.0.18 or later in configure.
34 Fixed crash that could occur if ES update transaction failed.
36 Configure enables the use of the crypt API - if available.

58 Fixed bug #252: Sort does not work.
60 Fixed bug #248: hit counts in combinatoric (and) searches in specific ..
64 Fixed bug #245: Time for getting records changes a lot based on record
67 Fixed bug #235: weird x-path results.
69 Avoid crash in ISAMB when isamb_pp_open gets ISAMB_POS = 0. In
70 this case EOF (no entries) is signalled. It fixes problem with
71 terms being deleted. See bug #109.
73 Fixed bug #169: Phrase term counts does not work. The bug exists in
76 Added mechanism to ignore leading articles when doing full-field indexing,
77 based on the character map files. See the manual for further discussion.
81 Fixed bug in record management. Releasing blocks could result in
84 Fixed bug in isam:b. A tree split could result in a lost item.
88 Add IDZebra.i to dist so that Perl extension builds again.
92 Added facility to make attibutes in grs.regx and grs.tcl filter using the
93 data command with argument -attribute <name> . The content of data is
94 the value of the attribute. This command should be used inside a
95 begin element , end element section.
97 Update zebra.nsi to NSIS 2.
99 Added a new 'cut' directive to charmaps (.chr files) which specifies that
100 only characters after the cutting char should be indexed.
102 Update Perl internals so that it matches the current Zebra API.
103 The recordGroup structure is no longer available. A group of resources
104 can still be referenced by setting groupName=>.. in various methods.
106 Maximum number of records to be sorted in a result set can be
107 specified by setting "sortmax". Default is 1000.
109 Allow use of string use attributes for regular attribute sets. The
110 name matches the name given in the attribute set file. All strings
111 starting with / are considered X-Path as usual.
113 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
114 element for XML tree. It may only pop off if -record is given.
116 Added grs.danbib filter - for Danish Bibliographic Centre.
118 Rename CHANGELOG to NEWS.
120 For text filter, return only header if elementSetName=H . elementSetName=R
121 returns contents only. Other elementSetName returns both header+content.
123 Added test for charmap and rusmarc.
125 Added feature charmaps (.chr) so that characters may be specified in
128 Fixed problem with encoding directive for charmap(.chr) files.
130 Allow Remote insert/delete/replace/update with record, recordIdNumber
131 (sysno) and/or recordIdOpaque(user supplied record Id). If both
132 IDs are omitted internal record ID match is assumed (recordId: - in
135 --- 1.3.15 2004/01/15

141 --- 1.3.14 2003/11/29
143 Fix bug with shadow and result set handling.
145 Implement MARCXML to ISO2709 conversion.
147 --- 1.3.13 2003/09/26
149 Add missing examples for Windows install.
151 Fix bug in regx filter to make it "greedy" again. This bug appeared
156 --- 1.3.12 2003/09/08
158 Fix XML error handling. Stop XML parse immediately if XML parse error
159 occur (i.e. produce one error only).
161 Zebra ignores "unsupported use attribute" for individual databases
162 when search multiple databases (unless all databases fail).
164 New filter grs.marcxml which works like grs.marc but produces MARCXML.
166 Added support for database deletion. It is possible to create/drop
167 a database from zebraidx utility. Note: only for isam:b.
169 Write zebrasrv.pid to lockdir.
171 Bug fix: result sets were not recovered correctly. Had to
172 add ODR handle for zebra_search_RPN in order to make it work.
174 Fixed a bug in regx filters that didn't do anchors (^) correctly.
176 Fixed a bug in searches with X-Path searches sometimes giving "extra"
179 Zebra server checks for zebrasrv.pid and refuses to start if it is already
180 locked by another (running) zebrasrv.
182 Fixed a bug with text being chunked in pieces for the grs.xml filter.
184 --- 1.3.11 2003/04/25
186 xelm code updates. xelm works regardless state of 'xpath enable/disable'
187 Avoid -L/usr/lib since that is already default library path.
189 Allow multiple updates within one transaction.
191 Fixed a bug with >2GB files (overflow in integer expression).
193 --- 1.3.10 2003/04/01
195 Fix linker error for Perl module.
197 Fix bug in and operation which in some cases could result in "extra"
198 hits. Bug was introduced in 1.3.5.
200 Fix bug in handling of schema conversion when producing numeric tags.
206 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
210 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
211 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
212 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
214 livrank: another experimental ranking algorithm. Source in livcode.c.
215 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
217 Contributed by Pete Mallinson, University of Liverpool.
219 Advanced MARC indexing. See doc/marc_indexing.xml
220 Oleg Kolobov <oleg at lib.tpu.ru>
222 Perl API updates and fixes.
223 Peter Popovics <pop at technomat.hu>
225 Fixed 'zebraidx delete'.
227 Implemented 'zebraidx clean'.
229 64-bit offsets for register files on WIN32 (no 2 GB limit).
231 Fixed a few memory leaks WRT sorting.
235 Fixed error handling : error code was not properly returned.
237 Support Truncation 104 (CCL).
241 Added missing source files for perl extension.
245 Implemented xelm directive.
247 Updated for newer version of YAZ (introduction of string schema).
249 Directory examples/zthes now part of distribution (was missing
250 in previous release).
252 New .abs directive, systag, that control where to put retrieval
253 information. The directive takes two arguments: system tag, element name.
254 System tag is one of : rank, sysno, size.
258 Perl Filter and Perl API. By Peter Popovics.
260 For zebra.cfg, if no profilePath is specified, directory
261 (prefix)/share/idzebra/tab
264 Zebra Examples in examples . Zebra tests in test.
266 Bug fix: sort index was not properly modified on
267 record updates/deletes.
269 Fix handling of character entities for sgml filter.
271 Move data1 to Zebra (used to be part of YAZ).
275 Fix character encoding of scan response terms.
277 Fix character decoding of scan request terms.
279 Fix ESpec handling (requires YAZ 1.9.1)
281 Fix searches for complete fields.
285 When name zebra is used in a filename or directory 'idzebra' is used
286 instead to avoid confusion with GNU zebra (routing software).
288 Zebra server stops with a fatal error if config file cannot be read.
290 New config setting, followLinks, that controls whether update of files
291 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
292 By default symbolic links are followed.
294 Fix MARC transfer . MARC fields had wrong data for multiple fields.
296 XML record reader moved from YAZ to Zebra, to make YAZ less
297 dependant on external libraries.
299 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
300 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
301 on systems that doesn't offer iconv.
303 XML record reader supports external system entities.
307 New .abs-directive "xpath" that takes one argument: "enable"
308 or "disable" to enable and disable XPath -indexing. If no "xpath"
309 direcive is found in .abs-file , XPath-indexing is disabled to ensure
310 backwards compatibility. For missing .abs-files XPath-indexing is
311 enabled so that such records are searchable.
313 Zebra warns about missing .abs-file only once (for each type).
315 Fixed a bug in file update where already-inserted files could
320 Zebra license changed to GNU GPL.
322 XPath-like queries used when RPN string attributes are used, eg.
323 @attr 1=/portal/title sometitle
324 @attr 1=/portal/title[@xml:lang=da] danishtitle
325 @attr 1=/portal/title/@xml:lang da
326 @attr 1=//title sometitle
328 Zebra uses UTF-8 internally:
329 1) New setting "encoding" for zebra.cfg that specifies encoding for
330 OCTET terms in queries and record encoding for most transfer syntaxes
331 (except those that use International Strings, such as GRS-1).
332 2) The encoding of International strings is UTF-8 by default. It
333 may be changed by character set negotiation. If character set
334 negotiation is in effect and if records are selected for conversion
335 these'll be converted to the selected character set - thus overriding
336 the encoding setting in zebra.cfg.
337 3) New directive "encoding" in .abs-files. This specifies the external
338 character encoding for files indexed by zebra. However, if records
339 themselves have an XML header that specifies and encoding that'll be used
342 XML filter (-t grs.xml).
344 Multiple registers. New setting in resource 'root' that holds base
345 directory for register(s). A group a databases may be put in separate
346 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
350 Fixes for Digital Unix
352 Implemented hits per term using USR:SearchResult-1.
354 New Zebra API. Locking system re-implemented.
356 --- 1.1.stable 2002/02/20
358 Rank weight can be controlled with attribute type 9. Default
359 value is 34. Recommended values between 1-36.
363 Updated for YAZ version 1.8.
365 Added support for termsets - a result set of terms matching
366 a given query. For @attr 8=<set> creates termset named <set>.
368 Added support for raw retrieval. Element Set Name R forces the
369 text filter which returns the record in its original form.
371 Added numerical sort - triggered by structure=numeric (4=109).
373 Remote record import using Z39.50 Extended Services and Segments.
375 Fixed bug where updating a database with user-defined attributes
376 could corrupt the register (bad storeKeys).
378 Multi-threaded version.
380 Fixed bug regarding proximity.
382 Documentation updates.
384 Fixed bug in record retrieval module that occured on 64-bit OSF
389 Fixed bug in makefile for WIN32.
391 Fixed bug in configure script - used bash-specific features.
395 Added support for multiple records in one file for filter grs.sgml.
397 Changed record index structure. New layout is incompatible with
398 previous releases. Added setting "recordcompression" to control
399 compression of records. Possible values are "none" (no
400 compression) and bzip2 (compression using libbz2).
402 Added XML transfer syntax support for retrieval of structured records.
403 Schema in CompSpec is recognised in retrieval of structured records.
405 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
406 that fails, the filter reads the file <filt>.flt (regx style filter).
408 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
409 Zebra's configure script automatically attempts to locate Tcl. For
410 manual Tcl configuration use option --with-tclconfig=<path> to specify
411 where Tcl's library files are located.
413 Implemented "compression" of Dictionary and ISAM system. Dictionary
416 Added "tagsysno" directive to zebra.cfg to control under which tag the
417 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
420 Added "tagrank" as above.
422 Changed file naming scheme for register files from <name>.mf.<no> to
425 Implemented "position"-flag for register type (as defined in
426 default.idx). When set to zero no position (or seqence number) is
427 saved in register for each word occurrence, thus saving some register
430 Implemented database mapping. Using mapdb one can specify a database
431 to be mapped to one or more physical databases. Usage:
432 mapdb <fromdb> <todb> ..
434 Added SOIF-filter. Thanks to Peter Valkenburg.
436 For the regx-filter "end element -record" may trigger a mark-of-record
437 if outer level is reached.
439 Tag sets may be typed in the reference to it. From the .abs-file the
440 "tagset" directive takes a third optional integer type for the tag set
441 referenced. From a .tag-file the "include" directive takes a third
442 optional type as well. The old "type" directive in the tag set itself
443 is still recognized but acts as the default type for the tag set.
445 Zebra supports the specification of arbitrary attributes sets, schemas
446 and tag sets, because of the change in YAZ' OID management system.
448 Fixed bug in Sort that caused it NOT to use character mapping as it
451 Zebra now uses GNU configure to generate Makefile(s).
453 Added un-optimised support for left and left/right truncation attributes.
455 Added support for relational operators on text when using RPN queries.
457 Added support for sort specifications in RPN queries. Type 7 specifies
458 'sort' where value 1=ascending, value 2=descending. The use attribute
459 specifies the field criteria as usual. The term specifies priority
460 where 0=first, 1=second, ...
462 Changed the way use attributes are specified in the recordId
465 Maximum number of databases in one Zebra register increased.
467 New setting, databasePath, which specifies that first directory during
468 update traversal is the database name (instead of a fixed one).
470 New setting, explainDatabase, which specifies that databases are
473 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
475 Implemented EXPLAIN database maintenance. Zebra automatically
476 generate - and update CategoryList, TargetInfo, DatabaseInfo,
477 AttributeSetInfo and AttributeDetails records at this stage. The
478 records may be transferred as GRS-1, SUTRS or Explain.
480 Fixed register spec so that colon isn't treated as size separator
481 unless followed by [0-9+-] in order to allow DOS drive specifications.
483 Fixed two bugs in ISAMC system.
485 Changed the way Zebra keeps its maintenance information about attribute
486 sets, available attributes, etc.. Records in "SGML" notation using an
487 EXPLAIN schema is now used when appropriate.
489 Bug fix: Index didn't handle update/insert/delete of the same record
490 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
491 first occurence of a record is considered.
493 Most searches now return correct number of hits.
495 New modular ranking system. Interested programmers are encouraged to
496 inspect rank1.c and improve the algorithm.
498 Bug fix: Lock files weren't removed as they should on NT.
500 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
501 specify a "sort register". Refer to the gils sample records which refer
502 to index type "s" which is specified as "sort" in the default.idx file.
503 Each sort criteria can either be Ascending or Descending and at most
504 three sort elements can be specified.
506 Bug fix: Character mapping didn't work for text files.
510 Simple ranked searches now return correct number of hits.
512 The test option (-s) only makes a read-lock on the index as well
513 as using read-only operations anywhere.
515 Moved towards generic character mapping. Configuration file default.idx
516 specifies character map files for register types w, p, u, etc.
518 Implemented "begin variant" for the sgml.regx - filter.
520 Fixed a few memory leaks.
522 Added support for C++, headers uses extern "C" for public definitions.
524 Bug fix: The show records facility (-s) only displayed information for
525 the first record in a file (and not for every record in the file).
527 Added option "-f <n>" to limit the logging of record operations. After
528 <n> records has been processed no logging is performed (unless errors
531 Bug fix: the compressed ISAM system didn't handle update operations
534 Added setting, "maxResultSetSize", to hold the number of records to
535 save in a result set.
537 Bug fix: Complete phrase did't work for search operations.
539 Bug fix: temporary result sets weren't deleted.
541 Reduced disk space for saved keys (storeKeys = 1).
543 Added optional, physical ANY (key replication)
545 Implemented proximity operator in search.
547 Bug fix: the path name buffers used by file match traversal routines
548 have been extended to support long file names.
550 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
551 configuration file. The resulting register without "storeKeys" is about
552 half the size, and the memory used by zebraidx during phase 2 (merge) is
553 reduced to a minimum.
555 Reworked the way Regexp-2 queries with error tolerance are handled and
556 specified. The documentation has been updated accordingly.
558 Bug fix: Zebrasrv didn't search correctly when queries contained masking
559 characters. This bug was introduced in 1.0a8.
561 Zebrasrv now tag records with the proper database name.
563 New settings, memMax and keyTmpDir.
565 Changed name of setting lockDir (previously called lockPath) and
566 setTmpDir (previously called tempSetPath).
568 Generalized and changed record type specifications. In short, there are:
570 grs.sgml structured, "SGML-like" syntax
571 grs.regx.<filter> structured, Regular expression filter
572 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
573 is the name of an abstract syntax file.
574 Bug fix: Result sets weren't sorted in operations involving boolean
575 operations with "ranked" operands.
579 Added national character-handling subsystem.
583 Small modifications to input filters and profiles.
585 Added support for SOIF syntax (with private OID).
589 Fixed buffer-size problem in indexing.
591 Added compression to temporary files for updating.
593 Added phrase registers.
595 Added dynamic mapping of search attribute to multiple termlists (ANY).
597 Scan support in multiple databases/registers.
599 Configuration settings are case-insensitive and single dash (-)
600 characters are ignored in comparisons.
602 The index processing ignores empty files - warning given.
604 New option to zebraidx (-V) displays version information.
608 Fixed problem in file-update system.
610 Fixed problem in shadow system; register was sometimes corrupted after
615 Fixed problems in the ISAM subsystem. Caused difficulties when updating
618 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
619 the rank and record number.
621 Fixed bug in the isam subsystem - caused a malfunction when accessing
622 words which occurred more than 10000 times.
624 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
627 Server can now run under inetd. Use option -i, and -w <directory> to
628 set working directory to desired location.
630 New zebraidx command: clean - removes temporary shadow files.
632 Fixed bug in ISAM system. Occurred rarely during register updates.
634 Logging during index merge phase is improved. The remaining running
637 Temporary files generated by zebraidx are removed after each run.
639 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
640 when doing scan operations in dictionaries with European characters.
644 A whole slew of updates, to make the first publicized release. Get the doc
649 Memory-problems in ISAM fixed. More blocktypes added to the default setup
650 to increase performance on larger databases.
652 Various minor changes in data management system.
656 A couple of portability-problems resolved.
658 Changed some malloc() to xmalloc().
