3 Fixed bug #602: Any extra terms appended to a wordlist with a hitcount
4 of 0, gets incorrect term count
6 Fixed bug #597: Support null missing key for sort.
10 Fixed bug #465: dup fields in ISO2709 retrieval.
12 Another fix for X-Path indexing. The previous fix, unfortunately, indexed
17 Fix X-Path attribute indexing. Bug #431.
21 Fixed bug #415: Strange truncation behavior.
23 Added 'melm' directive to absyn format to simplify config files
24 for MARC-style databases. See tab/marc21.abs for an example.
26 Added support for special slement set _sysno_ which returns a
27 record ID for a record packed as a SUTRS record.
31 Documented authentication facility in Zebra. Added zebra.cfg directive
32 'passwd.c' which specifies user accounts file with encrypted passwords. The
33 directive 'passwd' specifies user accounts file with clear-text passwords.
34 The previous version of Zebra used plain/clear text depending on
35 configuration automatically. That caused upgrade trouble. Bug #356.
39 Depend on YAZ 2.0.18 or later in configure.
41 Fixed crash that could occur if ES update transaction failed.
43 Configure enables the use of the crypt API - if available.
45 Fixed bug #304: Fuzzy search regExpr-2 did not use proper error distance
48 Fixed bug #305: Scan now handles negative preferred-position-in-response.

65 Fixed bug #252: Sort does not work.
67 Fixed bug #248: hit counts in combinatoric (and) searches in specific ..
71 Fixed bug #245: Time for getting records changes a lot based on record
74 Fixed bug #235: weird x-path results.
76 Avoid crash in ISAMB when isamb_pp_open gets ISAMB_POS = 0. In
77 this case EOF (no entries) is signalled. It fixes problem with
78 terms being deleted. See bug #109.
80 Fixed bug #169: Phrase term counts does not work. The bug exists in
83 Added mechanism to ignore leading articles when doing full-field indexing,
84 based on the character map files. See the manual for further discussion.
88 Fixed bug in record management. Releasing blocks could result in
91 Fixed bug in isam:b. A tree split could result in a lost item.
95 Add IDZebra.i to dist so that Perl extension builds again.
99 Added facility to make attibutes in grs.regx and grs.tcl filter using the
100 data command with argument -attribute <name> . The content of data is
101 the value of the attribute. This command should be used inside a
102 begin element , end element section.
104 Update zebra.nsi to NSIS 2.
106 Added a new 'cut' directive to charmaps (.chr files) which specifies that
107 only characters after the cutting char should be indexed.
109 Update Perl internals so that it matches the current Zebra API.
110 The recordGroup structure is no longer available. A group of resources
111 can still be referenced by setting groupName=>.. in various methods.
113 Maximum number of records to be sorted in a result set can be
114 specified by setting "sortmax". Default is 1000.
116 Allow use of string use attributes for regular attribute sets. The
117 name matches the name given in the attribute set file. All strings
118 starting with / are considered X-Path as usual.
120 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
121 element for XML tree. It may only pop off if -record is given.
123 Added grs.danbib filter - for Danish Bibliographic Centre.
125 Rename CHANGELOG to NEWS.
127 For text filter, return only header if elementSetName=H . elementSetName=R
128 returns contents only. Other elementSetName returns both header+content.
130 Added test for charmap and rusmarc.
132 Added feature charmaps (.chr) so that characters may be specified in
135 Fixed problem with encoding directive for charmap(.chr) files.
137 Allow Remote insert/delete/replace/update with record, recordIdNumber
138 (sysno) and/or recordIdOpaque(user supplied record Id). If both
139 IDs are omitted internal record ID match is assumed (recordId: - in
142 --- 1.3.15 2004/01/15

148 --- 1.3.14 2003/11/29
150 Fix bug with shadow and result set handling.
152 Implement MARCXML to ISO2709 conversion.
154 --- 1.3.13 2003/09/26
156 Add missing examples for Windows install.
158 Fix bug in regx filter to make it "greedy" again. This bug appeared
163 --- 1.3.12 2003/09/08
165 Fix XML error handling. Stop XML parse immediately if XML parse error
166 occur (i.e. produce one error only).
168 Zebra ignores "unsupported use attribute" for individual databases
169 when search multiple databases (unless all databases fail).
171 New filter grs.marcxml which works like grs.marc but produces MARCXML.
173 Added support for database deletion. It is possible to create/drop
174 a database from zebraidx utility. Note: only for isam:b.
176 Write zebrasrv.pid to lockdir.
178 Bug fix: result sets were not recovered correctly. Had to
179 add ODR handle for zebra_search_RPN in order to make it work.
181 Fixed a bug in regx filters that didn't do anchors (^) correctly.
183 Fixed a bug in searches with X-Path searches sometimes giving "extra"
186 Zebra server checks for zebrasrv.pid and refuses to start if it is already
187 locked by another (running) zebrasrv.
189 Fixed a bug with text being chunked in pieces for the grs.xml filter.
191 --- 1.3.11 2003/04/25
193 xelm code updates. xelm works regardless state of 'xpath enable/disable'
194 Avoid -L/usr/lib since that is already default library path.
196 Allow multiple updates within one transaction.
198 Fixed a bug with >2GB files (overflow in integer expression).
200 --- 1.3.10 2003/04/01
202 Fix linker error for Perl module.
204 Fix bug in and operation which in some cases could result in "extra"
205 hits. Bug was introduced in 1.3.5.
207 Fix bug in handling of schema conversion when producing numeric tags.
213 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
217 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
218 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
219 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
221 livrank: another experimental ranking algorithm. Source in livcode.c.
222 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
224 Contributed by Pete Mallinson, University of Liverpool.
226 Advanced MARC indexing. See doc/marc_indexing.xml
227 Oleg Kolobov <oleg at lib.tpu.ru>
229 Perl API updates and fixes.
230 Peter Popovics <pop at technomat.hu>
232 Fixed 'zebraidx delete'.
234 Implemented 'zebraidx clean'.
236 64-bit offsets for register files on WIN32 (no 2 GB limit).
238 Fixed a few memory leaks WRT sorting.
242 Fixed error handling : error code was not properly returned.
244 Support Truncation 104 (CCL).
248 Added missing source files for perl extension.
252 Implemented xelm directive.
254 Updated for newer version of YAZ (introduction of string schema).
256 Directory examples/zthes now part of distribution (was missing
257 in previous release).
259 New .abs directive, systag, that control where to put retrieval
260 information. The directive takes two arguments: system tag, element name.
261 System tag is one of : rank, sysno, size.
265 Perl Filter and Perl API. By Peter Popovics.
267 For zebra.cfg, if no profilePath is specified, directory
268 (prefix)/share/idzebra/tab
271 Zebra Examples in examples . Zebra tests in test.
273 Bug fix: sort index was not properly modified on
274 record updates/deletes.
276 Fix handling of character entities for sgml filter.
278 Move data1 to Zebra (used to be part of YAZ).
282 Fix character encoding of scan response terms.
284 Fix character decoding of scan request terms.
286 Fix ESpec handling (requires YAZ 1.9.1)
288 Fix searches for complete fields.
292 When name zebra is used in a filename or directory 'idzebra' is used
293 instead to avoid confusion with GNU zebra (routing software).
295 Zebra server stops with a fatal error if config file cannot be read.
297 New config setting, followLinks, that controls whether update of files
298 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
299 By default symbolic links are followed.
301 Fix MARC transfer . MARC fields had wrong data for multiple fields.
303 XML record reader moved from YAZ to Zebra, to make YAZ less
304 dependant on external libraries.
306 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
307 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
308 on systems that doesn't offer iconv.
310 XML record reader supports external system entities.
314 New .abs-directive "xpath" that takes one argument: "enable"
315 or "disable" to enable and disable XPath -indexing. If no "xpath"
316 direcive is found in .abs-file , XPath-indexing is disabled to ensure
317 backwards compatibility. For missing .abs-files XPath-indexing is
318 enabled so that such records are searchable.
320 Zebra warns about missing .abs-file only once (for each type).
322 Fixed a bug in file update where already-inserted files could
327 Zebra license changed to GNU GPL.
329 XPath-like queries used when RPN string attributes are used, eg.
330 @attr 1=/portal/title sometitle
331 @attr 1=/portal/title[@xml:lang=da] danishtitle
332 @attr 1=/portal/title/@xml:lang da
333 @attr 1=//title sometitle
335 Zebra uses UTF-8 internally:
336 1) New setting "encoding" for zebra.cfg that specifies encoding for
337 OCTET terms in queries and record encoding for most transfer syntaxes
338 (except those that use International Strings, such as GRS-1).
339 2) The encoding of International strings is UTF-8 by default. It
340 may be changed by character set negotiation. If character set
341 negotiation is in effect and if records are selected for conversion
342 these'll be converted to the selected character set - thus overriding
343 the encoding setting in zebra.cfg.
344 3) New directive "encoding" in .abs-files. This specifies the external
345 character encoding for files indexed by zebra. However, if records
346 themselves have an XML header that specifies and encoding that'll be used
349 XML filter (-t grs.xml).
351 Multiple registers. New setting in resource 'root' that holds base
352 directory for register(s). A group a databases may be put in separate
353 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
357 Fixes for Digital Unix
359 Implemented hits per term using USR:SearchResult-1.
361 New Zebra API. Locking system re-implemented.
363 --- 1.1.stable 2002/02/20
365 Rank weight can be controlled with attribute type 9. Default
366 value is 34. Recommended values between 1-36.
370 Updated for YAZ version 1.8.
372 Added support for termsets - a result set of terms matching
373 a given query. For @attr 8=<set> creates termset named <set>.
375 Added support for raw retrieval. Element Set Name R forces the
376 text filter which returns the record in its original form.
378 Added numerical sort - triggered by structure=numeric (4=109).
380 Remote record import using Z39.50 Extended Services and Segments.
382 Fixed bug where updating a database with user-defined attributes
383 could corrupt the register (bad storeKeys).
385 Multi-threaded version.
387 Fixed bug regarding proximity.
389 Documentation updates.
391 Fixed bug in record retrieval module that occured on 64-bit OSF
396 Fixed bug in makefile for WIN32.
398 Fixed bug in configure script - used bash-specific features.
402 Added support for multiple records in one file for filter grs.sgml.
404 Changed record index structure. New layout is incompatible with
405 previous releases. Added setting "recordcompression" to control
406 compression of records. Possible values are "none" (no
407 compression) and bzip2 (compression using libbz2).
409 Added XML transfer syntax support for retrieval of structured records.
410 Schema in CompSpec is recognised in retrieval of structured records.
412 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
413 that fails, the filter reads the file <filt>.flt (regx style filter).
415 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
416 Zebra's configure script automatically attempts to locate Tcl. For
417 manual Tcl configuration use option --with-tclconfig=<path> to specify
418 where Tcl's library files are located.
420 Implemented "compression" of Dictionary and ISAM system. Dictionary
423 Added "tagsysno" directive to zebra.cfg to control under which tag the
424 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
427 Added "tagrank" as above.
429 Changed file naming scheme for register files from <name>.mf.<no> to
432 Implemented "position"-flag for register type (as defined in
433 default.idx). When set to zero no position (or seqence number) is
434 saved in register for each word occurrence, thus saving some register
437 Implemented database mapping. Using mapdb one can specify a database
438 to be mapped to one or more physical databases. Usage:
439 mapdb <fromdb> <todb> ..
441 Added SOIF-filter. Thanks to Peter Valkenburg.
443 For the regx-filter "end element -record" may trigger a mark-of-record
444 if outer level is reached.
446 Tag sets may be typed in the reference to it. From the .abs-file the
447 "tagset" directive takes a third optional integer type for the tag set
448 referenced. From a .tag-file the "include" directive takes a third
449 optional type as well. The old "type" directive in the tag set itself
450 is still recognized but acts as the default type for the tag set.
452 Zebra supports the specification of arbitrary attributes sets, schemas
453 and tag sets, because of the change in YAZ' OID management system.
455 Fixed bug in Sort that caused it NOT to use character mapping as it
458 Zebra now uses GNU configure to generate Makefile(s).
460 Added un-optimised support for left and left/right truncation attributes.
462 Added support for relational operators on text when using RPN queries.
464 Added support for sort specifications in RPN queries. Type 7 specifies
465 'sort' where value 1=ascending, value 2=descending. The use attribute
466 specifies the field criteria as usual. The term specifies priority
467 where 0=first, 1=second, ...
469 Changed the way use attributes are specified in the recordId
472 Maximum number of databases in one Zebra register increased.
474 New setting, databasePath, which specifies that first directory during
475 update traversal is the database name (instead of a fixed one).
477 New setting, explainDatabase, which specifies that databases are
480 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
482 Implemented EXPLAIN database maintenance. Zebra automatically
483 generate - and update CategoryList, TargetInfo, DatabaseInfo,
484 AttributeSetInfo and AttributeDetails records at this stage. The
485 records may be transferred as GRS-1, SUTRS or Explain.
487 Fixed register spec so that colon isn't treated as size separator
488 unless followed by [0-9+-] in order to allow DOS drive specifications.
490 Fixed two bugs in ISAMC system.
492 Changed the way Zebra keeps its maintenance information about attribute
493 sets, available attributes, etc.. Records in "SGML" notation using an
494 EXPLAIN schema is now used when appropriate.
496 Bug fix: Index didn't handle update/insert/delete of the same record
497 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
498 first occurence of a record is considered.
500 Most searches now return correct number of hits.
502 New modular ranking system. Interested programmers are encouraged to
503 inspect rank1.c and improve the algorithm.
505 Bug fix: Lock files weren't removed as they should on NT.
507 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
508 specify a "sort register". Refer to the gils sample records which refer
509 to index type "s" which is specified as "sort" in the default.idx file.
510 Each sort criteria can either be Ascending or Descending and at most
511 three sort elements can be specified.
513 Bug fix: Character mapping didn't work for text files.
517 Simple ranked searches now return correct number of hits.
519 The test option (-s) only makes a read-lock on the index as well
520 as using read-only operations anywhere.
522 Moved towards generic character mapping. Configuration file default.idx
523 specifies character map files for register types w, p, u, etc.
525 Implemented "begin variant" for the sgml.regx - filter.
527 Fixed a few memory leaks.
529 Added support for C++, headers uses extern "C" for public definitions.
531 Bug fix: The show records facility (-s) only displayed information for
532 the first record in a file (and not for every record in the file).
534 Added option "-f <n>" to limit the logging of record operations. After
535 <n> records has been processed no logging is performed (unless errors
538 Bug fix: the compressed ISAM system didn't handle update operations
541 Added setting, "maxResultSetSize", to hold the number of records to
542 save in a result set.
544 Bug fix: Complete phrase did't work for search operations.
546 Bug fix: temporary result sets weren't deleted.
548 Reduced disk space for saved keys (storeKeys = 1).
550 Added optional, physical ANY (key replication)
552 Implemented proximity operator in search.
554 Bug fix: the path name buffers used by file match traversal routines
555 have been extended to support long file names.
557 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
558 configuration file. The resulting register without "storeKeys" is about
559 half the size, and the memory used by zebraidx during phase 2 (merge) is
560 reduced to a minimum.
562 Reworked the way Regexp-2 queries with error tolerance are handled and
563 specified. The documentation has been updated accordingly.
565 Bug fix: Zebrasrv didn't search correctly when queries contained masking
566 characters. This bug was introduced in 1.0a8.
568 Zebrasrv now tag records with the proper database name.
570 New settings, memMax and keyTmpDir.
572 Changed name of setting lockDir (previously called lockPath) and
573 setTmpDir (previously called tempSetPath).
575 Generalized and changed record type specifications. In short, there are:
577 grs.sgml structured, "SGML-like" syntax
578 grs.regx.<filter> structured, Regular expression filter
579 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
580 is the name of an abstract syntax file.
581 Bug fix: Result sets weren't sorted in operations involving boolean
582 operations with "ranked" operands.
586 Added national character-handling subsystem.
590 Small modifications to input filters and profiles.
592 Added support for SOIF syntax (with private OID).
596 Fixed buffer-size problem in indexing.
598 Added compression to temporary files for updating.
600 Added phrase registers.
602 Added dynamic mapping of search attribute to multiple termlists (ANY).
604 Scan support in multiple databases/registers.
606 Configuration settings are case-insensitive and single dash (-)
607 characters are ignored in comparisons.
609 The index processing ignores empty files - warning given.
611 New option to zebraidx (-V) displays version information.
615 Fixed problem in file-update system.
617 Fixed problem in shadow system; register was sometimes corrupted after
622 Fixed problems in the ISAM subsystem. Caused difficulties when updating
625 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
626 the rank and record number.
628 Fixed bug in the isam subsystem - caused a malfunction when accessing
629 words which occurred more than 10000 times.
631 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
634 Server can now run under inetd. Use option -i, and -w <directory> to
635 set working directory to desired location.
637 New zebraidx command: clean - removes temporary shadow files.
639 Fixed bug in ISAM system. Occurred rarely during register updates.
641 Logging during index merge phase is improved. The remaining running
644 Temporary files generated by zebraidx are removed after each run.
646 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
647 when doing scan operations in dictionaries with European characters.
651 A whole slew of updates, to make the first publicized release. Get the doc
656 Memory-problems in ISAM fixed. More blocktypes added to the default setup
657 to increase performance on larger databases.
659 Various minor changes in data management system.
663 A couple of portability-problems resolved.
665 Changed some malloc() to xmalloc().
