3 Updated Debian package to use sym links for zebraidx, zebrasrv.
5 Fixed bug in isamb (isam:b) regarding ISAM tree splitting.
7 Fixed problem with file locking during commit phase. This error was
12 Fixed bug #602: Any extra terms appended to a wordlist with a hitcount
13 of 0, gets incorrect term count
15 Fixed bug #597: Support null missing key for sort.
19 Fixed bug #465: dup fields in ISO2709 retrieval.
21 Another fix for X-Path indexing. The previous fix, unfortunately, indexed
26 Fix X-Path attribute indexing. Bug #431.
30 Fixed bug #415: Strange truncation behavior.
32 Added 'melm' directive to absyn format to simplify config files

35 Added support for special slement set _sysno_ which returns a
36 record ID for a record packed as a SUTRS record.
40 Documented authentication facility in Zebra. Added zebra.cfg directive
41 'passwd.c' which specifies user accounts file with encrypted passwords. The
42 directive 'passwd' specifies user accounts file with clear-text passwords.
43 The previous version of Zebra used plain/clear text depending on
44 configuration automatically. That caused upgrade trouble. Bug #356.
48 Depend on YAZ 2.0.18 or later in configure.
50 Fixed crash that could occur if ES update transaction failed.
52 Configure enables the use of the crypt API - if available.
54 Fixed bug #304: Fuzzy search regExpr-2 did not use proper error distance
57 Fixed bug #305: Scan now handles negative preferred-position-in-response.

83 Fixed bug #235: weird x-path results.
85 Avoid crash in ISAMB when isamb_pp_open gets ISAMB_POS = 0. In
86 this case EOF (no entries) is signalled. It fixes problem with
87 terms being deleted. See bug #109.
89 Fixed bug #169: Phrase term counts does not work. The bug exists in
92 Added mechanism to ignore leading articles when doing full-field indexing,
93 based on the character map files. See the manual for further discussion.
97 Fixed bug in record management. Releasing blocks could result in
100 Fixed bug in isam:b. A tree split could result in a lost item.
102 --- 1.3.17 2004/08/17
104 Add IDZebra.i to dist so that Perl extension builds again.
106 --- 1.3.16 2004/08/16
108 Added facility to make attibutes in grs.regx and grs.tcl filter using the
109 data command with argument -attribute <name> . The content of data is
110 the value of the attribute. This command should be used inside a
111 begin element , end element section.
113 Update zebra.nsi to NSIS 2.
115 Added a new 'cut' directive to charmaps (.chr files) which specifies that
116 only characters after the cutting char should be indexed.
118 Update Perl internals so that it matches the current Zebra API.
119 The recordGroup structure is no longer available. A group of resources
120 can still be referenced by setting groupName=>.. in various methods.
122 Maximum number of records to be sorted in a result set can be
123 specified by setting "sortmax". Default is 1000.
125 Allow use of string use attributes for regular attribute sets. The
126 name matches the name given in the attribute set file. All strings
127 starting with / are considered X-Path as usual.
129 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
130 element for XML tree. It may only pop off if -record is given.
132 Added grs.danbib filter - for Danish Bibliographic Centre.
134 Rename CHANGELOG to NEWS.
136 For text filter, return only header if elementSetName=H . elementSetName=R
137 returns contents only. Other elementSetName returns both header+content.
139 Added test for charmap and rusmarc.
141 Added feature charmaps (.chr) so that characters may be specified in
144 Fixed problem with encoding directive for charmap(.chr) files.
146 Allow Remote insert/delete/replace/update with record, recordIdNumber
147 (sysno) and/or recordIdOpaque(user supplied record Id). If both
148 IDs are omitted internal record ID match is assumed (recordId: - in
151 --- 1.3.15 2004/01/15

167 Fix bug in regx filter to make it "greedy" again. This bug appeared
172 --- 1.3.12 2003/09/08
174 Fix XML error handling. Stop XML parse immediately if XML parse error
175 occur (i.e. produce one error only).
177 Zebra ignores "unsupported use attribute" for individual databases
178 when search multiple databases (unless all databases fail).
180 New filter grs.marcxml which works like grs.marc but produces MARCXML.
182 Added support for database deletion. It is possible to create/drop
183 a database from zebraidx utility. Note: only for isam:b.
185 Write zebrasrv.pid to lockdir.
187 Bug fix: result sets were not recovered correctly. Had to
188 add ODR handle for zebra_search_RPN in order to make it work.
190 Fixed a bug in regx filters that didn't do anchors (^) correctly.
192 Fixed a bug in searches with X-Path searches sometimes giving "extra"
195 Zebra server checks for zebrasrv.pid and refuses to start if it is already
196 locked by another (running) zebrasrv.
198 Fixed a bug with text being chunked in pieces for the grs.xml filter.
200 --- 1.3.11 2003/04/25
202 xelm code updates. xelm works regardless state of 'xpath enable/disable'
203 Avoid -L/usr/lib since that is already default library path.
205 Allow multiple updates within one transaction.
207 Fixed a bug with >2GB files (overflow in integer expression).
209 --- 1.3.10 2003/04/01
211 Fix linker error for Perl module.
213 Fix bug in and operation which in some cases could result in "extra"
214 hits. Bug was introduced in 1.3.5.
216 Fix bug in handling of schema conversion when producing numeric tags.
222 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
226 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
227 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
228 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
230 livrank: another experimental ranking algorithm. Source in livcode.c.
231 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
233 Contributed by Pete Mallinson, University of Liverpool.
235 Advanced MARC indexing. See doc/marc_indexing.xml
236 Oleg Kolobov <oleg at lib.tpu.ru>
238 Perl API updates and fixes.
239 Peter Popovics <pop at technomat.hu>
241 Fixed 'zebraidx delete'.
243 Implemented 'zebraidx clean'.
245 64-bit offsets for register files on WIN32 (no 2 GB limit).
247 Fixed a few memory leaks WRT sorting.
251 Fixed error handling : error code was not properly returned.
253 Support Truncation 104 (CCL).
257 Added missing source files for perl extension.
261 Implemented xelm directive.
263 Updated for newer version of YAZ (introduction of string schema).
265 Directory examples/zthes now part of distribution (was missing
266 in previous release).
268 New .abs directive, systag, that control where to put retrieval
269 information. The directive takes two arguments: system tag, element name.
270 System tag is one of : rank, sysno, size.
274 Perl Filter and Perl API. By Peter Popovics.
276 For zebra.cfg, if no profilePath is specified, directory
277 (prefix)/share/idzebra/tab
280 Zebra Examples in examples . Zebra tests in test.
282 Bug fix: sort index was not properly modified on
283 record updates/deletes.
285 Fix handling of character entities for sgml filter.
287 Move data1 to Zebra (used to be part of YAZ).
291 Fix character encoding of scan response terms.
293 Fix character decoding of scan request terms.
295 Fix ESpec handling (requires YAZ 1.9.1)
297 Fix searches for complete fields.
301 When name zebra is used in a filename or directory 'idzebra' is used
302 instead to avoid confusion with GNU zebra (routing software).
304 Zebra server stops with a fatal error if config file cannot be read.
306 New config setting, followLinks, that controls whether update of files
307 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
308 By default symbolic links are followed.
310 Fix MARC transfer . MARC fields had wrong data for multiple fields.
312 XML record reader moved from YAZ to Zebra, to make YAZ less
313 dependant on external libraries.
315 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
316 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
317 on systems that doesn't offer iconv.
319 XML record reader supports external system entities.
323 New .abs-directive "xpath" that takes one argument: "enable"
324 or "disable" to enable and disable XPath -indexing. If no "xpath"
325 direcive is found in .abs-file , XPath-indexing is disabled to ensure
326 backwards compatibility. For missing .abs-files XPath-indexing is
327 enabled so that such records are searchable.
329 Zebra warns about missing .abs-file only once (for each type).
331 Fixed a bug in file update where already-inserted files could
336 Zebra license changed to GNU GPL.
338 XPath-like queries used when RPN string attributes are used, eg.
339 @attr 1=/portal/title sometitle
340 @attr 1=/portal/title[@xml:lang=da] danishtitle
341 @attr 1=/portal/title/@xml:lang da
342 @attr 1=//title sometitle
344 Zebra uses UTF-8 internally:
345 1) New setting "encoding" for zebra.cfg that specifies encoding for
346 OCTET terms in queries and record encoding for most transfer syntaxes
347 (except those that use International Strings, such as GRS-1).
348 2) The encoding of International strings is UTF-8 by default. It
349 may be changed by character set negotiation. If character set
350 negotiation is in effect and if records are selected for conversion
351 these'll be converted to the selected character set - thus overriding
352 the encoding setting in zebra.cfg.
353 3) New directive "encoding" in .abs-files. This specifies the external
354 character encoding for files indexed by zebra. However, if records
355 themselves have an XML header that specifies and encoding that'll be used
358 XML filter (-t grs.xml).
360 Multiple registers. New setting in resource 'root' that holds base
361 directory for register(s). A group a databases may be put in separate
362 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
366 Fixes for Digital Unix
368 Implemented hits per term using USR:SearchResult-1.
370 New Zebra API. Locking system re-implemented.
372 --- 1.1.stable 2002/02/20
374 Rank weight can be controlled with attribute type 9. Default
375 value is 34. Recommended values between 1-36.
379 Updated for YAZ version 1.8.
381 Added support for termsets - a result set of terms matching
382 a given query. For @attr 8=<set> creates termset named <set>.
384 Added support for raw retrieval. Element Set Name R forces the
385 text filter which returns the record in its original form.
387 Added numerical sort - triggered by structure=numeric (4=109).
389 Remote record import using Z39.50 Extended Services and Segments.
391 Fixed bug where updating a database with user-defined attributes
392 could corrupt the register (bad storeKeys).
394 Multi-threaded version.
396 Fixed bug regarding proximity.
398 Documentation updates.
400 Fixed bug in record retrieval module that occured on 64-bit OSF
405 Fixed bug in makefile for WIN32.
407 Fixed bug in configure script - used bash-specific features.
411 Added support for multiple records in one file for filter grs.sgml.
413 Changed record index structure. New layout is incompatible with
414 previous releases. Added setting "recordcompression" to control
415 compression of records. Possible values are "none" (no
416 compression) and bzip2 (compression using libbz2).
418 Added XML transfer syntax support for retrieval of structured records.
419 Schema in CompSpec is recognised in retrieval of structured records.
421 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
422 that fails, the filter reads the file <filt>.flt (regx style filter).
424 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
425 Zebra's configure script automatically attempts to locate Tcl. For
426 manual Tcl configuration use option --with-tclconfig=<path> to specify
427 where Tcl's library files are located.
429 Implemented "compression" of Dictionary and ISAM system. Dictionary
432 Added "tagsysno" directive to zebra.cfg to control under which tag the
433 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
436 Added "tagrank" as above.
438 Changed file naming scheme for register files from <name>.mf.<no> to
441 Implemented "position"-flag for register type (as defined in
442 default.idx). When set to zero no position (or seqence number) is
443 saved in register for each word occurrence, thus saving some register
446 Implemented database mapping. Using mapdb one can specify a database
447 to be mapped to one or more physical databases. Usage:
448 mapdb <fromdb> <todb> ..
450 Added SOIF-filter. Thanks to Peter Valkenburg.
452 For the regx-filter "end element -record" may trigger a mark-of-record
453 if outer level is reached.
455 Tag sets may be typed in the reference to it. From the .abs-file the
456 "tagset" directive takes a third optional integer type for the tag set
457 referenced. From a .tag-file the "include" directive takes a third
458 optional type as well. The old "type" directive in the tag set itself
459 is still recognized but acts as the default type for the tag set.
461 Zebra supports the specification of arbitrary attributes sets, schemas
462 and tag sets, because of the change in YAZ' OID management system.
464 Fixed bug in Sort that caused it NOT to use character mapping as it
467 Zebra now uses GNU configure to generate Makefile(s).
469 Added un-optimised support for left and left/right truncation attributes.
471 Added support for relational operators on text when using RPN queries.
473 Added support for sort specifications in RPN queries. Type 7 specifies
474 'sort' where value 1=ascending, value 2=descending. The use attribute
475 specifies the field criteria as usual. The term specifies priority
476 where 0=first, 1=second, ...
478 Changed the way use attributes are specified in the recordId
481 Maximum number of databases in one Zebra register increased.
483 New setting, databasePath, which specifies that first directory during
484 update traversal is the database name (instead of a fixed one).
486 New setting, explainDatabase, which specifies that databases are
489 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
491 Implemented EXPLAIN database maintenance. Zebra automatically
492 generate - and update CategoryList, TargetInfo, DatabaseInfo,
493 AttributeSetInfo and AttributeDetails records at this stage. The
494 records may be transferred as GRS-1, SUTRS or Explain.
496 Fixed register spec so that colon isn't treated as size separator
497 unless followed by [0-9+-] in order to allow DOS drive specifications.
499 Fixed two bugs in ISAMC system.
501 Changed the way Zebra keeps its maintenance information about attribute
502 sets, available attributes, etc.. Records in "SGML" notation using an
503 EXPLAIN schema is now used when appropriate.
505 Bug fix: Index didn't handle update/insert/delete of the same record
506 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
507 first occurence of a record is considered.
509 Most searches now return correct number of hits.
511 New modular ranking system. Interested programmers are encouraged to
512 inspect rank1.c and improve the algorithm.
514 Bug fix: Lock files weren't removed as they should on NT.
516 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
517 specify a "sort register". Refer to the gils sample records which refer
518 to index type "s" which is specified as "sort" in the default.idx file.
519 Each sort criteria can either be Ascending or Descending and at most
520 three sort elements can be specified.
522 Bug fix: Character mapping didn't work for text files.
526 Simple ranked searches now return correct number of hits.
528 The test option (-s) only makes a read-lock on the index as well
529 as using read-only operations anywhere.
531 Moved towards generic character mapping. Configuration file default.idx
532 specifies character map files for register types w, p, u, etc.
534 Implemented "begin variant" for the sgml.regx - filter.
536 Fixed a few memory leaks.
538 Added support for C++, headers uses extern "C" for public definitions.
540 Bug fix: The show records facility (-s) only displayed information for
541 the first record in a file (and not for every record in the file).
543 Added option "-f <n>" to limit the logging of record operations. After
544 <n> records has been processed no logging is performed (unless errors
547 Bug fix: the compressed ISAM system didn't handle update operations
550 Added setting, "maxResultSetSize", to hold the number of records to
551 save in a result set.
553 Bug fix: Complete phrase did't work for search operations.
555 Bug fix: temporary result sets weren't deleted.
557 Reduced disk space for saved keys (storeKeys = 1).
559 Added optional, physical ANY (key replication)
561 Implemented proximity operator in search.
563 Bug fix: the path name buffers used by file match traversal routines
564 have been extended to support long file names.
566 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
567 configuration file. The resulting register without "storeKeys" is about
568 half the size, and the memory used by zebraidx during phase 2 (merge) is
569 reduced to a minimum.
571 Reworked the way Regexp-2 queries with error tolerance are handled and
572 specified. The documentation has been updated accordingly.
574 Bug fix: Zebrasrv didn't search correctly when queries contained masking
575 characters. This bug was introduced in 1.0a8.
577 Zebrasrv now tag records with the proper database name.
579 New settings, memMax and keyTmpDir.
581 Changed name of setting lockDir (previously called lockPath) and
582 setTmpDir (previously called tempSetPath).
584 Generalized and changed record type specifications. In short, there are:
586 grs.sgml structured, "SGML-like" syntax
587 grs.regx.<filter> structured, Regular expression filter
588 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
589 is the name of an abstract syntax file.
590 Bug fix: Result sets weren't sorted in operations involving boolean
591 operations with "ranked" operands.
595 Added national character-handling subsystem.
599 Small modifications to input filters and profiles.
601 Added support for SOIF syntax (with private OID).
605 Fixed buffer-size problem in indexing.
607 Added compression to temporary files for updating.
609 Added phrase registers.
611 Added dynamic mapping of search attribute to multiple termlists (ANY).
613 Scan support in multiple databases/registers.
615 Configuration settings are case-insensitive and single dash (-)
616 characters are ignored in comparisons.
618 The index processing ignores empty files - warning given.
620 New option to zebraidx (-V) displays version information.
624 Fixed problem in file-update system.
626 Fixed problem in shadow system; register was sometimes corrupted after
631 Fixed problems in the ISAM subsystem. Caused difficulties when updating
634 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
635 the rank and record number.
637 Fixed bug in the isam subsystem - caused a malfunction when accessing
638 words which occurred more than 10000 times.
640 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
643 Server can now run under inetd. Use option -i, and -w <directory> to
644 set working directory to desired location.
646 New zebraidx command: clean - removes temporary shadow files.
648 Fixed bug in ISAM system. Occurred rarely during register updates.
650 Logging during index merge phase is improved. The remaining running
653 Temporary files generated by zebraidx are removed after each run.
655 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
656 when doing scan operations in dictionaries with European characters.
660 A whole slew of updates, to make the first publicized release. Get the doc
665 Memory-problems in ISAM fixed. More blocktypes added to the default setup
666 to increase performance on larger databases.
668 Various minor changes in data management system.
672 A couple of portability-problems resolved.
674 Changed some malloc() to xmalloc().
