3 Fix X-Path attribute indexing.
7 Fixed bug #415: Strange truncation behavior.
9 Added 'melm' directive to absyn format to simplify config files
10 for MARC-style databases. See tab/marc21.abs for an example.
12 Added support for special slement set _sysno_ which returns a
13 record ID for a record packed as a SUTRS record.
17 Documented authentication facility in Zebra. Added zebra.cfg directive
18 'passwd.c' which specifies user accounts file with encrypted passwords. The
19 directive 'passwd' specifies user accounts file with clear-text passwords.
20 The previous version of Zebra used plain/clear text depending on
21 configuration automatically. That caused upgrade trouble. Bug #356.
25 Depend on YAZ 2.0.18 or later in configure.
27 Fixed crash that could occur if ES update transaction failed.
29 Configure enables the use of the crypt API - if available.
31 Fixed bug #304: Fuzzy search regExpr-2 did not use proper error distance
34 Fixed bug #305: Scan now handles negative preferred-position-in-response.
36 Implemented the 'equivalent' directive for .chr-files.
40 For configure, support threading again. It was removed by mistake

45 Fixed bug #259: Second indicator lost in MARC records
49 Fixed bug #253: Setting group.database not honored
51 Fixed bug #252: Sort does not work.
53 Fixed bug #248: hit counts in combinatoric (and) searches in specific ..
57 Fixed bug #245: Time for getting records changes a lot based on record
60 Fixed bug #235: weird x-path results.
62 Avoid crash in ISAMB when isamb_pp_open gets ISAMB_POS = 0. In
63 this case EOF (no entries) is signalled. It fixes problem with
64 terms being deleted. See bug #109.
66 Fixed bug #169: Phrase term counts does not work. The bug exists in
69 Added mechanism to ignore leading articles when doing full-field indexing,
70 based on the character map files. See the manual for further discussion.
74 Fixed bug in record management. Releasing blocks could result in
77 Fixed bug in isam:b. A tree split could result in a lost item.
81 Add IDZebra.i to dist so that Perl extension builds again.
85 Added facility to make attibutes in grs.regx and grs.tcl filter using the
86 data command with argument -attribute <name> . The content of data is
87 the value of the attribute. This command should be used inside a
88 begin element , end element section.
90 Update zebra.nsi to NSIS 2.
92 Added a new 'cut' directive to charmaps (.chr files) which specifies that
93 only characters after the cutting char should be indexed.
95 Update Perl internals so that it matches the current Zebra API.
96 The recordGroup structure is no longer available. A group of resources
97 can still be referenced by setting groupName=>.. in various methods.
99 Maximum number of records to be sorted in a result set can be
100 specified by setting "sortmax". Default is 1000.
102 Allow use of string use attributes for regular attribute sets. The
103 name matches the name given in the attribute set file. All strings
104 starting with / are considered X-Path as usual.
106 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
107 element for XML tree. It may only pop off if -record is given.
109 Added grs.danbib filter - for Danish Bibliographic Centre.
111 Rename CHANGELOG to NEWS.
113 For text filter, return only header if elementSetName=H . elementSetName=R
114 returns contents only. Other elementSetName returns both header+content.
116 Added test for charmap and rusmarc.
118 Added feature charmaps (.chr) so that characters may be specified in
121 Fixed problem with encoding directive for charmap(.chr) files.
123 Allow Remote insert/delete/replace/update with record, recordIdNumber
124 (sysno) and/or recordIdOpaque(user supplied record Id). If both
125 IDs are omitted internal record ID match is assumed (recordId: - in
128 --- 1.3.15 2004/01/15

134 --- 1.3.14 2003/11/29
136 Fix bug with shadow and result set handling.
138 Implement MARCXML to ISO2709 conversion.
140 --- 1.3.13 2003/09/26
142 Add missing examples for Windows install.
144 Fix bug in regx filter to make it "greedy" again. This bug appeared
149 --- 1.3.12 2003/09/08
151 Fix XML error handling. Stop XML parse immediately if XML parse error
152 occur (i.e. produce one error only).
154 Zebra ignores "unsupported use attribute" for individual databases
155 when search multiple databases (unless all databases fail).
157 New filter grs.marcxml which works like grs.marc but produces MARCXML.
159 Added support for database deletion. It is possible to create/drop
160 a database from zebraidx utility. Note: only for isam:b.
162 Write zebrasrv.pid to lockdir.
164 Bug fix: result sets were not recovered correctly. Had to
165 add ODR handle for zebra_search_RPN in order to make it work.
167 Fixed a bug in regx filters that didn't do anchors (^) correctly.
169 Fixed a bug in searches with X-Path searches sometimes giving "extra"
172 Zebra server checks for zebrasrv.pid and refuses to start if it is already
173 locked by another (running) zebrasrv.
175 Fixed a bug with text being chunked in pieces for the grs.xml filter.
177 --- 1.3.11 2003/04/25
179 xelm code updates. xelm works regardless state of 'xpath enable/disable'
180 Avoid -L/usr/lib since that is already default library path.
182 Allow multiple updates within one transaction.
184 Fixed a bug with >2GB files (overflow in integer expression).
186 --- 1.3.10 2003/04/01
188 Fix linker error for Perl module.
190 Fix bug in and operation which in some cases could result in "extra"
191 hits. Bug was introduced in 1.3.5.
193 Fix bug in handling of schema conversion when producing numeric tags.
199 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
203 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
204 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
205 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
207 livrank: another experimental ranking algorithm. Source in livcode.c.
208 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
210 Contributed by Pete Mallinson, University of Liverpool.
212 Advanced MARC indexing. See doc/marc_indexing.xml
213 Oleg Kolobov <oleg at lib.tpu.ru>
215 Perl API updates and fixes.
216 Peter Popovics <pop at technomat.hu>
218 Fixed 'zebraidx delete'.
220 Implemented 'zebraidx clean'.
222 64-bit offsets for register files on WIN32 (no 2 GB limit).
224 Fixed a few memory leaks WRT sorting.
228 Fixed error handling : error code was not properly returned.
230 Support Truncation 104 (CCL).
234 Added missing source files for perl extension.
238 Implemented xelm directive.
240 Updated for newer version of YAZ (introduction of string schema).
242 Directory examples/zthes now part of distribution (was missing
243 in previous release).
245 New .abs directive, systag, that control where to put retrieval
246 information. The directive takes two arguments: system tag, element name.
247 System tag is one of : rank, sysno, size.
251 Perl Filter and Perl API. By Peter Popovics.
253 For zebra.cfg, if no profilePath is specified, directory
254 (prefix)/share/idzebra/tab
257 Zebra Examples in examples . Zebra tests in test.
259 Bug fix: sort index was not properly modified on
260 record updates/deletes.
262 Fix handling of character entities for sgml filter.
264 Move data1 to Zebra (used to be part of YAZ).
268 Fix character encoding of scan response terms.
270 Fix character decoding of scan request terms.
272 Fix ESpec handling (requires YAZ 1.9.1)
274 Fix searches for complete fields.
278 When name zebra is used in a filename or directory 'idzebra' is used
279 instead to avoid confusion with GNU zebra (routing software).
281 Zebra server stops with a fatal error if config file cannot be read.
283 New config setting, followLinks, that controls whether update of files
284 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
285 By default symbolic links are followed.
287 Fix MARC transfer . MARC fields had wrong data for multiple fields.
289 XML record reader moved from YAZ to Zebra, to make YAZ less
290 dependant on external libraries.
292 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
293 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
294 on systems that doesn't offer iconv.
296 XML record reader supports external system entities.
300 New .abs-directive "xpath" that takes one argument: "enable"
301 or "disable" to enable and disable XPath -indexing. If no "xpath"
302 direcive is found in .abs-file , XPath-indexing is disabled to ensure
303 backwards compatibility. For missing .abs-files XPath-indexing is
304 enabled so that such records are searchable.
306 Zebra warns about missing .abs-file only once (for each type).
308 Fixed a bug in file update where already-inserted files could
313 Zebra license changed to GNU GPL.
315 XPath-like queries used when RPN string attributes are used, eg.
316 @attr 1=/portal/title sometitle
317 @attr 1=/portal/title[@xml:lang=da] danishtitle
318 @attr 1=/portal/title/@xml:lang da
319 @attr 1=//title sometitle
321 Zebra uses UTF-8 internally:
322 1) New setting "encoding" for zebra.cfg that specifies encoding for
323 OCTET terms in queries and record encoding for most transfer syntaxes
324 (except those that use International Strings, such as GRS-1).
325 2) The encoding of International strings is UTF-8 by default. It
326 may be changed by character set negotiation. If character set
327 negotiation is in effect and if records are selected for conversion
328 these'll be converted to the selected character set - thus overriding
329 the encoding setting in zebra.cfg.
330 3) New directive "encoding" in .abs-files. This specifies the external
331 character encoding for files indexed by zebra. However, if records
332 themselves have an XML header that specifies and encoding that'll be used
335 XML filter (-t grs.xml).
337 Multiple registers. New setting in resource 'root' that holds base
338 directory for register(s). A group a databases may be put in separate
339 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
343 Fixes for Digital Unix
345 Implemented hits per term using USR:SearchResult-1.
347 New Zebra API. Locking system re-implemented.
349 --- 1.1.stable 2002/02/20
351 Rank weight can be controlled with attribute type 9. Default
352 value is 34. Recommended values between 1-36.
356 Updated for YAZ version 1.8.
358 Added support for termsets - a result set of terms matching
359 a given query. For @attr 8=<set> creates termset named <set>.
361 Added support for raw retrieval. Element Set Name R forces the
362 text filter which returns the record in its original form.
364 Added numerical sort - triggered by structure=numeric (4=109).
366 Remote record import using Z39.50 Extended Services and Segments.
368 Fixed bug where updating a database with user-defined attributes
369 could corrupt the register (bad storeKeys).
371 Multi-threaded version.
373 Fixed bug regarding proximity.
375 Documentation updates.
377 Fixed bug in record retrieval module that occured on 64-bit OSF
382 Fixed bug in makefile for WIN32.
384 Fixed bug in configure script - used bash-specific features.
388 Added support for multiple records in one file for filter grs.sgml.
390 Changed record index structure. New layout is incompatible with
391 previous releases. Added setting "recordcompression" to control
392 compression of records. Possible values are "none" (no
393 compression) and bzip2 (compression using libbz2).
395 Added XML transfer syntax support for retrieval of structured records.
396 Schema in CompSpec is recognised in retrieval of structured records.
398 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
399 that fails, the filter reads the file <filt>.flt (regx style filter).
401 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
402 Zebra's configure script automatically attempts to locate Tcl. For
403 manual Tcl configuration use option --with-tclconfig=<path> to specify
404 where Tcl's library files are located.
406 Implemented "compression" of Dictionary and ISAM system. Dictionary
409 Added "tagsysno" directive to zebra.cfg to control under which tag the
410 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
413 Added "tagrank" as above.
415 Changed file naming scheme for register files from <name>.mf.<no> to
418 Implemented "position"-flag for register type (as defined in
419 default.idx). When set to zero no position (or seqence number) is
420 saved in register for each word occurrence, thus saving some register
423 Implemented database mapping. Using mapdb one can specify a database
424 to be mapped to one or more physical databases. Usage:
425 mapdb <fromdb> <todb> ..
427 Added SOIF-filter. Thanks to Peter Valkenburg.
429 For the regx-filter "end element -record" may trigger a mark-of-record
430 if outer level is reached.
432 Tag sets may be typed in the reference to it. From the .abs-file the
433 "tagset" directive takes a third optional integer type for the tag set
434 referenced. From a .tag-file the "include" directive takes a third
435 optional type as well. The old "type" directive in the tag set itself
436 is still recognized but acts as the default type for the tag set.
438 Zebra supports the specification of arbitrary attributes sets, schemas
439 and tag sets, because of the change in YAZ' OID management system.
441 Fixed bug in Sort that caused it NOT to use character mapping as it
444 Zebra now uses GNU configure to generate Makefile(s).
446 Added un-optimised support for left and left/right truncation attributes.
448 Added support for relational operators on text when using RPN queries.
450 Added support for sort specifications in RPN queries. Type 7 specifies
451 'sort' where value 1=ascending, value 2=descending. The use attribute
452 specifies the field criteria as usual. The term specifies priority
453 where 0=first, 1=second, ...
455 Changed the way use attributes are specified in the recordId
458 Maximum number of databases in one Zebra register increased.
460 New setting, databasePath, which specifies that first directory during
461 update traversal is the database name (instead of a fixed one).
463 New setting, explainDatabase, which specifies that databases are
466 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
468 Implemented EXPLAIN database maintenance. Zebra automatically
469 generate - and update CategoryList, TargetInfo, DatabaseInfo,
470 AttributeSetInfo and AttributeDetails records at this stage. The
471 records may be transferred as GRS-1, SUTRS or Explain.
473 Fixed register spec so that colon isn't treated as size separator
474 unless followed by [0-9+-] in order to allow DOS drive specifications.
476 Fixed two bugs in ISAMC system.
478 Changed the way Zebra keeps its maintenance information about attribute
479 sets, available attributes, etc.. Records in "SGML" notation using an
480 EXPLAIN schema is now used when appropriate.
482 Bug fix: Index didn't handle update/insert/delete of the same record
483 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
484 first occurence of a record is considered.
486 Most searches now return correct number of hits.
488 New modular ranking system. Interested programmers are encouraged to
489 inspect rank1.c and improve the algorithm.
491 Bug fix: Lock files weren't removed as they should on NT.
493 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
494 specify a "sort register". Refer to the gils sample records which refer
495 to index type "s" which is specified as "sort" in the default.idx file.
496 Each sort criteria can either be Ascending or Descending and at most
497 three sort elements can be specified.
499 Bug fix: Character mapping didn't work for text files.
503 Simple ranked searches now return correct number of hits.
505 The test option (-s) only makes a read-lock on the index as well
506 as using read-only operations anywhere.
508 Moved towards generic character mapping. Configuration file default.idx
509 specifies character map files for register types w, p, u, etc.
511 Implemented "begin variant" for the sgml.regx - filter.
513 Fixed a few memory leaks.
515 Added support for C++, headers uses extern "C" for public definitions.
517 Bug fix: The show records facility (-s) only displayed information for
518 the first record in a file (and not for every record in the file).
520 Added option "-f <n>" to limit the logging of record operations. After
521 <n> records has been processed no logging is performed (unless errors
524 Bug fix: the compressed ISAM system didn't handle update operations
527 Added setting, "maxResultSetSize", to hold the number of records to
528 save in a result set.
530 Bug fix: Complete phrase did't work for search operations.
532 Bug fix: temporary result sets weren't deleted.
534 Reduced disk space for saved keys (storeKeys = 1).
536 Added optional, physical ANY (key replication)
538 Implemented proximity operator in search.
540 Bug fix: the path name buffers used by file match traversal routines
541 have been extended to support long file names.
543 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
544 configuration file. The resulting register without "storeKeys" is about
545 half the size, and the memory used by zebraidx during phase 2 (merge) is
546 reduced to a minimum.
548 Reworked the way Regexp-2 queries with error tolerance are handled and
549 specified. The documentation has been updated accordingly.
551 Bug fix: Zebrasrv didn't search correctly when queries contained masking
552 characters. This bug was introduced in 1.0a8.
554 Zebrasrv now tag records with the proper database name.
556 New settings, memMax and keyTmpDir.
558 Changed name of setting lockDir (previously called lockPath) and
559 setTmpDir (previously called tempSetPath).
561 Generalized and changed record type specifications. In short, there are:
563 grs.sgml structured, "SGML-like" syntax
564 grs.regx.<filter> structured, Regular expression filter
565 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
566 is the name of an abstract syntax file.
567 Bug fix: Result sets weren't sorted in operations involving boolean
568 operations with "ranked" operands.
572 Added national character-handling subsystem.
576 Small modifications to input filters and profiles.
578 Added support for SOIF syntax (with private OID).
582 Fixed buffer-size problem in indexing.
584 Added compression to temporary files for updating.
586 Added phrase registers.
588 Added dynamic mapping of search attribute to multiple termlists (ANY).
590 Scan support in multiple databases/registers.
592 Configuration settings are case-insensitive and single dash (-)
593 characters are ignored in comparisons.
595 The index processing ignores empty files - warning given.
597 New option to zebraidx (-V) displays version information.
601 Fixed problem in file-update system.
603 Fixed problem in shadow system; register was sometimes corrupted after
608 Fixed problems in the ISAM subsystem. Caused difficulties when updating
611 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
612 the rank and record number.
614 Fixed bug in the isam subsystem - caused a malfunction when accessing
615 words which occurred more than 10000 times.
617 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
620 Server can now run under inetd. Use option -i, and -w <directory> to
621 set working directory to desired location.
623 New zebraidx command: clean - removes temporary shadow files.
625 Fixed bug in ISAM system. Occurred rarely during register updates.
627 Logging during index merge phase is improved. The remaining running
630 Temporary files generated by zebraidx are removed after each run.
632 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
633 when doing scan operations in dictionaries with European characters.
637 A whole slew of updates, to make the first publicized release. Get the doc
642 Memory-problems in ISAM fixed. More blocktypes added to the default setup
643 to increase performance on larger databases.
645 Various minor changes in data management system.
649 A couple of portability-problems resolved.
651 Changed some malloc() to xmalloc().
