3 Fixed bug #529: multiple simultaneous updates by extended services trashes
8 Fixed bug #47: Commit needs to check for roll-back.
10 Fixed bug #672: Trailing characters in password are ignored
12 Added extra presence check for tcl.h, because some systems have
13 tclConfig.sh installed even though Tcl C headers are missing.
17 Optimized melm performance.
19 Do not use sync(2) during commit (but rely on sync'd individual files).
23 Updated Debian package to use sym links for zebraidx, zebrasrv.
25 Fixed bug in isamb (isam:b) regarding ISAM tree splitting.
27 Fixed problem with file locking during commit phase. This error was

46 Fix X-Path attribute indexing. Bug #431.
50 Fixed bug #415: Strange truncation behavior.
52 Added 'melm' directive to absyn format to simplify config files
53 for MARC-style databases. See tab/marc21.abs for an example.
55 Added support for special slement set _sysno_ which returns a
56 record ID for a record packed as a SUTRS record.
60 Documented authentication facility in Zebra. Added zebra.cfg directive
61 'passwd.c' which specifies user accounts file with encrypted passwords. The
62 directive 'passwd' specifies user accounts file with clear-text passwords.
63 The previous version of Zebra used plain/clear text depending on
64 configuration automatically. That caused upgrade trouble. Bug #356.
68 Depend on YAZ 2.0.18 or later in configure.
70 Fixed crash that could occur if ES update transaction failed.
72 Configure enables the use of the crypt API - if available.

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

103 Fixed bug #235: weird x-path results.
105 Avoid crash in ISAMB when isamb_pp_open gets ISAMB_POS = 0. In
106 this case EOF (no entries) is signalled. It fixes problem with
107 terms being deleted. See bug #109.
109 Fixed bug #169: Phrase term counts does not work. The bug exists in
112 Added mechanism to ignore leading articles when doing full-field indexing,
113 based on the character map files. See the manual for further discussion.
115 --- 1.3.18 2004/08/20
117 Fixed bug in record management. Releasing blocks could result in
120 Fixed bug in isam:b. A tree split could result in a lost item.
122 --- 1.3.17 2004/08/17
124 Add IDZebra.i to dist so that Perl extension builds again.
126 --- 1.3.16 2004/08/16
128 Added facility to make attibutes in grs.regx and grs.tcl filter using the
129 data command with argument -attribute <name> . The content of data is
130 the value of the attribute. This command should be used inside a
131 begin element , end element section.
133 Update zebra.nsi to NSIS 2.
135 Added a new 'cut' directive to charmaps (.chr files) which specifies that
136 only characters after the cutting char should be indexed.
138 Update Perl internals so that it matches the current Zebra API.
139 The recordGroup structure is no longer available. A group of resources
140 can still be referenced by setting groupName=>.. in various methods.
142 Maximum number of records to be sorted in a result set can be
143 specified by setting "sortmax". Default is 1000.
145 Allow use of string use attributes for regular attribute sets. The
146 name matches the name given in the attribute set file. All strings
147 starting with / are considered X-Path as usual.
149 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
150 element for XML tree. It may only pop off if -record is given.
152 Added grs.danbib filter - for Danish Bibliographic Centre.
154 Rename CHANGELOG to NEWS.
156 For text filter, return only header if elementSetName=H . elementSetName=R
157 returns contents only. Other elementSetName returns both header+content.
159 Added test for charmap and rusmarc.
161 Added feature charmaps (.chr) so that characters may be specified in
164 Fixed problem with encoding directive for charmap(.chr) files.
166 Allow Remote insert/delete/replace/update with record, recordIdNumber
167 (sysno) and/or recordIdOpaque(user supplied record Id). If both
168 IDs are omitted internal record ID match is assumed (recordId: - in
171 --- 1.3.15 2004/01/15

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