6 Fixed bug #47: Commit needs to check for roll-back.
8 Fixed bug #672: Trailing characters in password are ignored
10 Added extra presence check for tcl.h, because some systems have
11 tclConfig.sh installed even though Tcl C headers are missing.
15 Optimized melm performance.
17 Do not use sync(2) during commit (but rely on sync'd individual files).
21 Updated Debian package to use sym links for zebraidx, zebrasrv.
23 Fixed bug in isamb (isam:b) regarding ISAM tree splitting.
25 Fixed problem with file locking during commit phase. This error was

53 Added support for special slement set _sysno_ which returns a
54 record ID for a record packed as a SUTRS record.
58 Documented authentication facility in Zebra. Added zebra.cfg directive
59 'passwd.c' which specifies user accounts file with encrypted passwords. The
60 directive 'passwd' specifies user accounts file with clear-text passwords.
61 The previous version of Zebra used plain/clear text depending on
62 configuration automatically. That caused upgrade trouble. Bug #356.
66 Depend on YAZ 2.0.18 or later in configure.
68 Fixed crash that could occur if ES update transaction failed.
70 Configure enables the use of the crypt API - if available.

75 Fixed bug #305: Scan now handles negative preferred-position-in-response.
77 Implemented the 'equivalent' directive for .chr-files.
81 For configure, support threading again. It was removed by mistake

101 Fixed bug #235: weird x-path results.
103 Avoid crash in ISAMB when isamb_pp_open gets ISAMB_POS = 0. In
104 this case EOF (no entries) is signalled. It fixes problem with
105 terms being deleted. See bug #109.
107 Fixed bug #169: Phrase term counts does not work. The bug exists in
110 Added mechanism to ignore leading articles when doing full-field indexing,
111 based on the character map files. See the manual for further discussion.
113 --- 1.3.18 2004/08/20
115 Fixed bug in record management. Releasing blocks could result in
118 Fixed bug in isam:b. A tree split could result in a lost item.
120 --- 1.3.17 2004/08/17
122 Add IDZebra.i to dist so that Perl extension builds again.
124 --- 1.3.16 2004/08/16
126 Added facility to make attibutes in grs.regx and grs.tcl filter using the
127 data command with argument -attribute <name> . The content of data is
128 the value of the attribute. This command should be used inside a
129 begin element , end element section.
131 Update zebra.nsi to NSIS 2.
133 Added a new 'cut' directive to charmaps (.chr files) which specifies that
134 only characters after the cutting char should be indexed.
136 Update Perl internals so that it matches the current Zebra API.
137 The recordGroup structure is no longer available. A group of resources
138 can still be referenced by setting groupName=>.. in various methods.
140 Maximum number of records to be sorted in a result set can be
141 specified by setting "sortmax". Default is 1000.
143 Allow use of string use attributes for regular attribute sets. The
144 name matches the name given in the attribute set file. All strings
145 starting with / are considered X-Path as usual.
147 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
148 element for XML tree. It may only pop off if -record is given.
150 Added grs.danbib filter - for Danish Bibliographic Centre.
152 Rename CHANGELOG to NEWS.
154 For text filter, return only header if elementSetName=H . elementSetName=R
155 returns contents only. Other elementSetName returns both header+content.
157 Added test for charmap and rusmarc.
159 Added feature charmaps (.chr) so that characters may be specified in
162 Fixed problem with encoding directive for charmap(.chr) files.
164 Allow Remote insert/delete/replace/update with record, recordIdNumber
165 (sysno) and/or recordIdOpaque(user supplied record Id). If both
166 IDs are omitted internal record ID match is assumed (recordId: - in
169 --- 1.3.15 2004/01/15

175 --- 1.3.14 2003/11/29
177 Fix bug with shadow and result set handling.
179 Implement MARCXML to ISO2709 conversion.
181 --- 1.3.13 2003/09/26
183 Add missing examples for Windows install.
185 Fix bug in regx filter to make it "greedy" again. This bug appeared
190 --- 1.3.12 2003/09/08
192 Fix XML error handling. Stop XML parse immediately if XML parse error
193 occur (i.e. produce one error only).
195 Zebra ignores "unsupported use attribute" for individual databases
196 when search multiple databases (unless all databases fail).
198 New filter grs.marcxml which works like grs.marc but produces MARCXML.
200 Added support for database deletion. It is possible to create/drop
201 a database from zebraidx utility. Note: only for isam:b.
203 Write zebrasrv.pid to lockdir.
205 Bug fix: result sets were not recovered correctly. Had to
206 add ODR handle for zebra_search_RPN in order to make it work.
208 Fixed a bug in regx filters that didn't do anchors (^) correctly.
210 Fixed a bug in searches with X-Path searches sometimes giving "extra"
213 Zebra server checks for zebrasrv.pid and refuses to start if it is already
214 locked by another (running) zebrasrv.
216 Fixed a bug with text being chunked in pieces for the grs.xml filter.
218 --- 1.3.11 2003/04/25
220 xelm code updates. xelm works regardless state of 'xpath enable/disable'
221 Avoid -L/usr/lib since that is already default library path.
223 Allow multiple updates within one transaction.
225 Fixed a bug with >2GB files (overflow in integer expression).
227 --- 1.3.10 2003/04/01
229 Fix linker error for Perl module.
231 Fix bug in and operation which in some cases could result in "extra"
232 hits. Bug was introduced in 1.3.5.
234 Fix bug in handling of schema conversion when producing numeric tags.
240 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
244 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
245 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
246 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
248 livrank: another experimental ranking algorithm. Source in livcode.c.
249 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
251 Contributed by Pete Mallinson, University of Liverpool.
253 Advanced MARC indexing. See doc/marc_indexing.xml
254 Oleg Kolobov <oleg at lib.tpu.ru>
256 Perl API updates and fixes.
257 Peter Popovics <pop at technomat.hu>
259 Fixed 'zebraidx delete'.
261 Implemented 'zebraidx clean'.
263 64-bit offsets for register files on WIN32 (no 2 GB limit).
265 Fixed a few memory leaks WRT sorting.
269 Fixed error handling : error code was not properly returned.
271 Support Truncation 104 (CCL).
275 Added missing source files for perl extension.
279 Implemented xelm directive.
281 Updated for newer version of YAZ (introduction of string schema).
283 Directory examples/zthes now part of distribution (was missing
284 in previous release).
286 New .abs directive, systag, that control where to put retrieval
287 information. The directive takes two arguments: system tag, element name.
288 System tag is one of : rank, sysno, size.
292 Perl Filter and Perl API. By Peter Popovics.
294 For zebra.cfg, if no profilePath is specified, directory
295 (prefix)/share/idzebra/tab
298 Zebra Examples in examples . Zebra tests in test.
300 Bug fix: sort index was not properly modified on
301 record updates/deletes.
303 Fix handling of character entities for sgml filter.
305 Move data1 to Zebra (used to be part of YAZ).
309 Fix character encoding of scan response terms.
311 Fix character decoding of scan request terms.
313 Fix ESpec handling (requires YAZ 1.9.1)
315 Fix searches for complete fields.
319 When name zebra is used in a filename or directory 'idzebra' is used
320 instead to avoid confusion with GNU zebra (routing software).
322 Zebra server stops with a fatal error if config file cannot be read.
324 New config setting, followLinks, that controls whether update of files
325 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
326 By default symbolic links are followed.
328 Fix MARC transfer . MARC fields had wrong data for multiple fields.
330 XML record reader moved from YAZ to Zebra, to make YAZ less
331 dependant on external libraries.
333 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
334 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
335 on systems that doesn't offer iconv.
337 XML record reader supports external system entities.
341 New .abs-directive "xpath" that takes one argument: "enable"
342 or "disable" to enable and disable XPath -indexing. If no "xpath"
343 direcive is found in .abs-file , XPath-indexing is disabled to ensure
344 backwards compatibility. For missing .abs-files XPath-indexing is
345 enabled so that such records are searchable.
347 Zebra warns about missing .abs-file only once (for each type).
349 Fixed a bug in file update where already-inserted files could
354 Zebra license changed to GNU GPL.
356 XPath-like queries used when RPN string attributes are used, eg.
357 @attr 1=/portal/title sometitle
358 @attr 1=/portal/title[@xml:lang=da] danishtitle
359 @attr 1=/portal/title/@xml:lang da
360 @attr 1=//title sometitle
362 Zebra uses UTF-8 internally:
363 1) New setting "encoding" for zebra.cfg that specifies encoding for
364 OCTET terms in queries and record encoding for most transfer syntaxes
365 (except those that use International Strings, such as GRS-1).
366 2) The encoding of International strings is UTF-8 by default. It
367 may be changed by character set negotiation. If character set
368 negotiation is in effect and if records are selected for conversion
369 these'll be converted to the selected character set - thus overriding
370 the encoding setting in zebra.cfg.
371 3) New directive "encoding" in .abs-files. This specifies the external
372 character encoding for files indexed by zebra. However, if records
373 themselves have an XML header that specifies and encoding that'll be used
376 XML filter (-t grs.xml).
378 Multiple registers. New setting in resource 'root' that holds base
379 directory for register(s). A group a databases may be put in separate
380 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
384 Fixes for Digital Unix
386 Implemented hits per term using USR:SearchResult-1.
388 New Zebra API. Locking system re-implemented.
390 --- 1.1.stable 2002/02/20
392 Rank weight can be controlled with attribute type 9. Default
393 value is 34. Recommended values between 1-36.
397 Updated for YAZ version 1.8.
399 Added support for termsets - a result set of terms matching
400 a given query. For @attr 8=<set> creates termset named <set>.
402 Added support for raw retrieval. Element Set Name R forces the
403 text filter which returns the record in its original form.
405 Added numerical sort - triggered by structure=numeric (4=109).
407 Remote record import using Z39.50 Extended Services and Segments.
409 Fixed bug where updating a database with user-defined attributes
410 could corrupt the register (bad storeKeys).
412 Multi-threaded version.
414 Fixed bug regarding proximity.
416 Documentation updates.
418 Fixed bug in record retrieval module that occured on 64-bit OSF
423 Fixed bug in makefile for WIN32.
425 Fixed bug in configure script - used bash-specific features.
429 Added support for multiple records in one file for filter grs.sgml.
431 Changed record index structure. New layout is incompatible with
432 previous releases. Added setting "recordcompression" to control
433 compression of records. Possible values are "none" (no
434 compression) and bzip2 (compression using libbz2).
436 Added XML transfer syntax support for retrieval of structured records.
437 Schema in CompSpec is recognised in retrieval of structured records.
439 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
440 that fails, the filter reads the file <filt>.flt (regx style filter).
442 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
443 Zebra's configure script automatically attempts to locate Tcl. For
444 manual Tcl configuration use option --with-tclconfig=<path> to specify
445 where Tcl's library files are located.
447 Implemented "compression" of Dictionary and ISAM system. Dictionary
450 Added "tagsysno" directive to zebra.cfg to control under which tag the
451 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
454 Added "tagrank" as above.
456 Changed file naming scheme for register files from <name>.mf.<no> to
459 Implemented "position"-flag for register type (as defined in
460 default.idx). When set to zero no position (or seqence number) is
461 saved in register for each word occurrence, thus saving some register
464 Implemented database mapping. Using mapdb one can specify a database
465 to be mapped to one or more physical databases. Usage:
466 mapdb <fromdb> <todb> ..
468 Added SOIF-filter. Thanks to Peter Valkenburg.
470 For the regx-filter "end element -record" may trigger a mark-of-record
471 if outer level is reached.
473 Tag sets may be typed in the reference to it. From the .abs-file the
474 "tagset" directive takes a third optional integer type for the tag set
475 referenced. From a .tag-file the "include" directive takes a third
476 optional type as well. The old "type" directive in the tag set itself
477 is still recognized but acts as the default type for the tag set.
479 Zebra supports the specification of arbitrary attributes sets, schemas
480 and tag sets, because of the change in YAZ' OID management system.
482 Fixed bug in Sort that caused it NOT to use character mapping as it
485 Zebra now uses GNU configure to generate Makefile(s).
487 Added un-optimised support for left and left/right truncation attributes.
489 Added support for relational operators on text when using RPN queries.
491 Added support for sort specifications in RPN queries. Type 7 specifies
492 'sort' where value 1=ascending, value 2=descending. The use attribute
493 specifies the field criteria as usual. The term specifies priority
494 where 0=first, 1=second, ...
496 Changed the way use attributes are specified in the recordId
499 Maximum number of databases in one Zebra register increased.
501 New setting, databasePath, which specifies that first directory during
502 update traversal is the database name (instead of a fixed one).
504 New setting, explainDatabase, which specifies that databases are
507 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
509 Implemented EXPLAIN database maintenance. Zebra automatically
510 generate - and update CategoryList, TargetInfo, DatabaseInfo,
511 AttributeSetInfo and AttributeDetails records at this stage. The
512 records may be transferred as GRS-1, SUTRS or Explain.
514 Fixed register spec so that colon isn't treated as size separator
515 unless followed by [0-9+-] in order to allow DOS drive specifications.
517 Fixed two bugs in ISAMC system.
519 Changed the way Zebra keeps its maintenance information about attribute
520 sets, available attributes, etc.. Records in "SGML" notation using an
521 EXPLAIN schema is now used when appropriate.
523 Bug fix: Index didn't handle update/insert/delete of the same record
524 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
525 first occurence of a record is considered.
527 Most searches now return correct number of hits.
529 New modular ranking system. Interested programmers are encouraged to
530 inspect rank1.c and improve the algorithm.
532 Bug fix: Lock files weren't removed as they should on NT.
534 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
535 specify a "sort register". Refer to the gils sample records which refer
536 to index type "s" which is specified as "sort" in the default.idx file.
537 Each sort criteria can either be Ascending or Descending and at most
538 three sort elements can be specified.
540 Bug fix: Character mapping didn't work for text files.
544 Simple ranked searches now return correct number of hits.
546 The test option (-s) only makes a read-lock on the index as well
547 as using read-only operations anywhere.
549 Moved towards generic character mapping. Configuration file default.idx
550 specifies character map files for register types w, p, u, etc.
552 Implemented "begin variant" for the sgml.regx - filter.
554 Fixed a few memory leaks.
556 Added support for C++, headers uses extern "C" for public definitions.
558 Bug fix: The show records facility (-s) only displayed information for
559 the first record in a file (and not for every record in the file).
561 Added option "-f <n>" to limit the logging of record operations. After
562 <n> records has been processed no logging is performed (unless errors
565 Bug fix: the compressed ISAM system didn't handle update operations
568 Added setting, "maxResultSetSize", to hold the number of records to
569 save in a result set.
571 Bug fix: Complete phrase did't work for search operations.
573 Bug fix: temporary result sets weren't deleted.
575 Reduced disk space for saved keys (storeKeys = 1).
577 Added optional, physical ANY (key replication)
579 Implemented proximity operator in search.
581 Bug fix: the path name buffers used by file match traversal routines
582 have been extended to support long file names.
584 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
585 configuration file. The resulting register without "storeKeys" is about
586 half the size, and the memory used by zebraidx during phase 2 (merge) is
587 reduced to a minimum.
589 Reworked the way Regexp-2 queries with error tolerance are handled and
590 specified. The documentation has been updated accordingly.
592 Bug fix: Zebrasrv didn't search correctly when queries contained masking
593 characters. This bug was introduced in 1.0a8.
595 Zebrasrv now tag records with the proper database name.
597 New settings, memMax and keyTmpDir.
599 Changed name of setting lockDir (previously called lockPath) and
600 setTmpDir (previously called tempSetPath).
602 Generalized and changed record type specifications. In short, there are:
604 grs.sgml structured, "SGML-like" syntax
605 grs.regx.<filter> structured, Regular expression filter
606 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
607 is the name of an abstract syntax file.
608 Bug fix: Result sets weren't sorted in operations involving boolean
609 operations with "ranked" operands.
613 Added national character-handling subsystem.
617 Small modifications to input filters and profiles.
619 Added support for SOIF syntax (with private OID).
623 Fixed buffer-size problem in indexing.
625 Added compression to temporary files for updating.
627 Added phrase registers.
629 Added dynamic mapping of search attribute to multiple termlists (ANY).
631 Scan support in multiple databases/registers.
633 Configuration settings are case-insensitive and single dash (-)
634 characters are ignored in comparisons.
636 The index processing ignores empty files - warning given.
638 New option to zebraidx (-V) displays version information.
642 Fixed problem in file-update system.
644 Fixed problem in shadow system; register was sometimes corrupted after
649 Fixed problems in the ISAM subsystem. Caused difficulties when updating
652 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
653 the rank and record number.
655 Fixed bug in the isam subsystem - caused a malfunction when accessing
656 words which occurred more than 10000 times.
658 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
661 Server can now run under inetd. Use option -i, and -w <directory> to
662 set working directory to desired location.
664 New zebraidx command: clean - removes temporary shadow files.
666 Fixed bug in ISAM system. Occurred rarely during register updates.
668 Logging during index merge phase is improved. The remaining running
671 Temporary files generated by zebraidx are removed after each run.
673 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
674 when doing scan operations in dictionaries with European characters.
678 A whole slew of updates, to make the first publicized release. Get the doc
683 Memory-problems in ISAM fixed. More blocktypes added to the default setup
684 to increase performance on larger databases.
686 Various minor changes in data management system.
690 A couple of portability-problems resolved.
692 Changed some malloc() to xmalloc().
