1 Fixed bug #597: Support null missing key for sort.
5 Fixed bug #465: dup fields in ISO2709 retrieval.
7 Another fix for X-Path indexing. The previous fix, unfortunately, indexed
12 Fix X-Path attribute indexing. Bug #431.
16 Fixed bug #415: Strange truncation behavior.
18 Added 'melm' directive to absyn format to simplify config files
19 for MARC-style databases. See tab/marc21.abs for an example.
21 Added support for special slement set _sysno_ which returns a
22 record ID for a record packed as a SUTRS record.
26 Documented authentication facility in Zebra. Added zebra.cfg directive
27 'passwd.c' which specifies user accounts file with encrypted passwords. The
28 directive 'passwd' specifies user accounts file with clear-text passwords.
29 The previous version of Zebra used plain/clear text depending on
30 configuration automatically. That caused upgrade trouble. Bug #356.
34 Depend on YAZ 2.0.18 or later in configure.
36 Fixed crash that could occur if ES update transaction failed.
38 Configure enables the use of the crypt API - if available.

58 Fixed bug #253: Setting group.database not honored
60 Fixed bug #252: Sort does not work.
62 Fixed bug #248: hit counts in combinatoric (and) searches in specific ..
66 Fixed bug #245: Time for getting records changes a lot based on record
69 Fixed bug #235: weird x-path results.
71 Avoid crash in ISAMB when isamb_pp_open gets ISAMB_POS = 0. In
72 this case EOF (no entries) is signalled. It fixes problem with
73 terms being deleted. See bug #109.
75 Fixed bug #169: Phrase term counts does not work. The bug exists in
78 Added mechanism to ignore leading articles when doing full-field indexing,
79 based on the character map files. See the manual for further discussion.
83 Fixed bug in record management. Releasing blocks could result in
86 Fixed bug in isam:b. A tree split could result in a lost item.
90 Add IDZebra.i to dist so that Perl extension builds again.
94 Added facility to make attibutes in grs.regx and grs.tcl filter using the
95 data command with argument -attribute <name> . The content of data is
96 the value of the attribute. This command should be used inside a
97 begin element , end element section.
99 Update zebra.nsi to NSIS 2.
101 Added a new 'cut' directive to charmaps (.chr files) which specifies that
102 only characters after the cutting char should be indexed.
104 Update Perl internals so that it matches the current Zebra API.
105 The recordGroup structure is no longer available. A group of resources
106 can still be referenced by setting groupName=>.. in various methods.
108 Maximum number of records to be sorted in a result set can be
109 specified by setting "sortmax". Default is 1000.
111 Allow use of string use attributes for regular attribute sets. The
112 name matches the name given in the attribute set file. All strings
113 starting with / are considered X-Path as usual.
115 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
116 element for XML tree. It may only pop off if -record is given.
118 Added grs.danbib filter - for Danish Bibliographic Centre.
120 Rename CHANGELOG to NEWS.
122 For text filter, return only header if elementSetName=H . elementSetName=R
123 returns contents only. Other elementSetName returns both header+content.
125 Added test for charmap and rusmarc.
127 Added feature charmaps (.chr) so that characters may be specified in
130 Fixed problem with encoding directive for charmap(.chr) files.
132 Allow Remote insert/delete/replace/update with record, recordIdNumber
133 (sysno) and/or recordIdOpaque(user supplied record Id). If both
134 IDs are omitted internal record ID match is assumed (recordId: - in
137 --- 1.3.15 2004/01/15

141 Fix base address for MARC output.
143 --- 1.3.14 2003/11/29
145 Fix bug with shadow and result set handling.
147 Implement MARCXML to ISO2709 conversion.
149 --- 1.3.13 2003/09/26
151 Add missing examples for Windows install.
153 Fix bug in regx filter to make it "greedy" again. This bug appeared
158 --- 1.3.12 2003/09/08
160 Fix XML error handling. Stop XML parse immediately if XML parse error
161 occur (i.e. produce one error only).
163 Zebra ignores "unsupported use attribute" for individual databases
164 when search multiple databases (unless all databases fail).
166 New filter grs.marcxml which works like grs.marc but produces MARCXML.
168 Added support for database deletion. It is possible to create/drop
169 a database from zebraidx utility. Note: only for isam:b.
171 Write zebrasrv.pid to lockdir.
173 Bug fix: result sets were not recovered correctly. Had to
174 add ODR handle for zebra_search_RPN in order to make it work.
176 Fixed a bug in regx filters that didn't do anchors (^) correctly.
178 Fixed a bug in searches with X-Path searches sometimes giving "extra"
181 Zebra server checks for zebrasrv.pid and refuses to start if it is already
182 locked by another (running) zebrasrv.
184 Fixed a bug with text being chunked in pieces for the grs.xml filter.
186 --- 1.3.11 2003/04/25
188 xelm code updates. xelm works regardless state of 'xpath enable/disable'
189 Avoid -L/usr/lib since that is already default library path.
191 Allow multiple updates within one transaction.
193 Fixed a bug with >2GB files (overflow in integer expression).
195 --- 1.3.10 2003/04/01
197 Fix linker error for Perl module.
199 Fix bug in and operation which in some cases could result in "extra"
200 hits. Bug was introduced in 1.3.5.
202 Fix bug in handling of schema conversion when producing numeric tags.
208 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
212 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
213 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
214 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
216 livrank: another experimental ranking algorithm. Source in livcode.c.
217 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
219 Contributed by Pete Mallinson, University of Liverpool.
221 Advanced MARC indexing. See doc/marc_indexing.xml
222 Oleg Kolobov <oleg at lib.tpu.ru>
224 Perl API updates and fixes.
225 Peter Popovics <pop at technomat.hu>
227 Fixed 'zebraidx delete'.
229 Implemented 'zebraidx clean'.
231 64-bit offsets for register files on WIN32 (no 2 GB limit).
233 Fixed a few memory leaks WRT sorting.
237 Fixed error handling : error code was not properly returned.
239 Support Truncation 104 (CCL).
243 Added missing source files for perl extension.
247 Implemented xelm directive.
249 Updated for newer version of YAZ (introduction of string schema).
251 Directory examples/zthes now part of distribution (was missing
252 in previous release).
254 New .abs directive, systag, that control where to put retrieval
255 information. The directive takes two arguments: system tag, element name.
256 System tag is one of : rank, sysno, size.
260 Perl Filter and Perl API. By Peter Popovics.
262 For zebra.cfg, if no profilePath is specified, directory
263 (prefix)/share/idzebra/tab
266 Zebra Examples in examples . Zebra tests in test.
268 Bug fix: sort index was not properly modified on
269 record updates/deletes.
271 Fix handling of character entities for sgml filter.
273 Move data1 to Zebra (used to be part of YAZ).
277 Fix character encoding of scan response terms.
279 Fix character decoding of scan request terms.
281 Fix ESpec handling (requires YAZ 1.9.1)
283 Fix searches for complete fields.
287 When name zebra is used in a filename or directory 'idzebra' is used
288 instead to avoid confusion with GNU zebra (routing software).
290 Zebra server stops with a fatal error if config file cannot be read.
292 New config setting, followLinks, that controls whether update of files
293 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
294 By default symbolic links are followed.
296 Fix MARC transfer . MARC fields had wrong data for multiple fields.
298 XML record reader moved from YAZ to Zebra, to make YAZ less
299 dependant on external libraries.
301 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
302 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
303 on systems that doesn't offer iconv.
305 XML record reader supports external system entities.
309 New .abs-directive "xpath" that takes one argument: "enable"
310 or "disable" to enable and disable XPath -indexing. If no "xpath"
311 direcive is found in .abs-file , XPath-indexing is disabled to ensure
312 backwards compatibility. For missing .abs-files XPath-indexing is
313 enabled so that such records are searchable.
315 Zebra warns about missing .abs-file only once (for each type).
317 Fixed a bug in file update where already-inserted files could
322 Zebra license changed to GNU GPL.
324 XPath-like queries used when RPN string attributes are used, eg.
325 @attr 1=/portal/title sometitle
326 @attr 1=/portal/title[@xml:lang=da] danishtitle
327 @attr 1=/portal/title/@xml:lang da
328 @attr 1=//title sometitle
330 Zebra uses UTF-8 internally:
331 1) New setting "encoding" for zebra.cfg that specifies encoding for
332 OCTET terms in queries and record encoding for most transfer syntaxes
333 (except those that use International Strings, such as GRS-1).
334 2) The encoding of International strings is UTF-8 by default. It
335 may be changed by character set negotiation. If character set
336 negotiation is in effect and if records are selected for conversion
337 these'll be converted to the selected character set - thus overriding
338 the encoding setting in zebra.cfg.
339 3) New directive "encoding" in .abs-files. This specifies the external
340 character encoding for files indexed by zebra. However, if records
341 themselves have an XML header that specifies and encoding that'll be used
344 XML filter (-t grs.xml).
346 Multiple registers. New setting in resource 'root' that holds base
347 directory for register(s). A group a databases may be put in separate
348 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
352 Fixes for Digital Unix
354 Implemented hits per term using USR:SearchResult-1.
356 New Zebra API. Locking system re-implemented.
358 --- 1.1.stable 2002/02/20
360 Rank weight can be controlled with attribute type 9. Default
361 value is 34. Recommended values between 1-36.
365 Updated for YAZ version 1.8.
367 Added support for termsets - a result set of terms matching
368 a given query. For @attr 8=<set> creates termset named <set>.
370 Added support for raw retrieval. Element Set Name R forces the
371 text filter which returns the record in its original form.
373 Added numerical sort - triggered by structure=numeric (4=109).
375 Remote record import using Z39.50 Extended Services and Segments.
377 Fixed bug where updating a database with user-defined attributes
378 could corrupt the register (bad storeKeys).
380 Multi-threaded version.
382 Fixed bug regarding proximity.
384 Documentation updates.
386 Fixed bug in record retrieval module that occured on 64-bit OSF
391 Fixed bug in makefile for WIN32.
393 Fixed bug in configure script - used bash-specific features.
397 Added support for multiple records in one file for filter grs.sgml.
399 Changed record index structure. New layout is incompatible with
400 previous releases. Added setting "recordcompression" to control
401 compression of records. Possible values are "none" (no
402 compression) and bzip2 (compression using libbz2).
404 Added XML transfer syntax support for retrieval of structured records.
405 Schema in CompSpec is recognised in retrieval of structured records.
407 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
408 that fails, the filter reads the file <filt>.flt (regx style filter).
410 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
411 Zebra's configure script automatically attempts to locate Tcl. For
412 manual Tcl configuration use option --with-tclconfig=<path> to specify
413 where Tcl's library files are located.
415 Implemented "compression" of Dictionary and ISAM system. Dictionary
418 Added "tagsysno" directive to zebra.cfg to control under which tag the
419 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
422 Added "tagrank" as above.
424 Changed file naming scheme for register files from <name>.mf.<no> to
427 Implemented "position"-flag for register type (as defined in
428 default.idx). When set to zero no position (or seqence number) is
429 saved in register for each word occurrence, thus saving some register
432 Implemented database mapping. Using mapdb one can specify a database
433 to be mapped to one or more physical databases. Usage:
434 mapdb <fromdb> <todb> ..
436 Added SOIF-filter. Thanks to Peter Valkenburg.
438 For the regx-filter "end element -record" may trigger a mark-of-record
439 if outer level is reached.
441 Tag sets may be typed in the reference to it. From the .abs-file the
442 "tagset" directive takes a third optional integer type for the tag set
443 referenced. From a .tag-file the "include" directive takes a third
444 optional type as well. The old "type" directive in the tag set itself
445 is still recognized but acts as the default type for the tag set.
447 Zebra supports the specification of arbitrary attributes sets, schemas
448 and tag sets, because of the change in YAZ' OID management system.
450 Fixed bug in Sort that caused it NOT to use character mapping as it
453 Zebra now uses GNU configure to generate Makefile(s).
455 Added un-optimised support for left and left/right truncation attributes.
457 Added support for relational operators on text when using RPN queries.
459 Added support for sort specifications in RPN queries. Type 7 specifies
460 'sort' where value 1=ascending, value 2=descending. The use attribute
461 specifies the field criteria as usual. The term specifies priority
462 where 0=first, 1=second, ...
464 Changed the way use attributes are specified in the recordId
467 Maximum number of databases in one Zebra register increased.
469 New setting, databasePath, which specifies that first directory during
470 update traversal is the database name (instead of a fixed one).
472 New setting, explainDatabase, which specifies that databases are
475 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
477 Implemented EXPLAIN database maintenance. Zebra automatically
478 generate - and update CategoryList, TargetInfo, DatabaseInfo,
479 AttributeSetInfo and AttributeDetails records at this stage. The
480 records may be transferred as GRS-1, SUTRS or Explain.
482 Fixed register spec so that colon isn't treated as size separator
483 unless followed by [0-9+-] in order to allow DOS drive specifications.
485 Fixed two bugs in ISAMC system.
487 Changed the way Zebra keeps its maintenance information about attribute
488 sets, available attributes, etc.. Records in "SGML" notation using an
489 EXPLAIN schema is now used when appropriate.
491 Bug fix: Index didn't handle update/insert/delete of the same record
492 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
493 first occurence of a record is considered.
495 Most searches now return correct number of hits.
497 New modular ranking system. Interested programmers are encouraged to
498 inspect rank1.c and improve the algorithm.
500 Bug fix: Lock files weren't removed as they should on NT.
502 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
503 specify a "sort register". Refer to the gils sample records which refer
504 to index type "s" which is specified as "sort" in the default.idx file.
505 Each sort criteria can either be Ascending or Descending and at most
506 three sort elements can be specified.
508 Bug fix: Character mapping didn't work for text files.
512 Simple ranked searches now return correct number of hits.
514 The test option (-s) only makes a read-lock on the index as well
515 as using read-only operations anywhere.
517 Moved towards generic character mapping. Configuration file default.idx
518 specifies character map files for register types w, p, u, etc.
520 Implemented "begin variant" for the sgml.regx - filter.
522 Fixed a few memory leaks.
524 Added support for C++, headers uses extern "C" for public definitions.
526 Bug fix: The show records facility (-s) only displayed information for
527 the first record in a file (and not for every record in the file).
529 Added option "-f <n>" to limit the logging of record operations. After
530 <n> records has been processed no logging is performed (unless errors
533 Bug fix: the compressed ISAM system didn't handle update operations
536 Added setting, "maxResultSetSize", to hold the number of records to
537 save in a result set.
539 Bug fix: Complete phrase did't work for search operations.
541 Bug fix: temporary result sets weren't deleted.
543 Reduced disk space for saved keys (storeKeys = 1).
545 Added optional, physical ANY (key replication)
547 Implemented proximity operator in search.
549 Bug fix: the path name buffers used by file match traversal routines
550 have been extended to support long file names.
552 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
553 configuration file. The resulting register without "storeKeys" is about
554 half the size, and the memory used by zebraidx during phase 2 (merge) is
555 reduced to a minimum.
557 Reworked the way Regexp-2 queries with error tolerance are handled and
558 specified. The documentation has been updated accordingly.
560 Bug fix: Zebrasrv didn't search correctly when queries contained masking
561 characters. This bug was introduced in 1.0a8.
563 Zebrasrv now tag records with the proper database name.
565 New settings, memMax and keyTmpDir.
567 Changed name of setting lockDir (previously called lockPath) and
568 setTmpDir (previously called tempSetPath).
570 Generalized and changed record type specifications. In short, there are:
572 grs.sgml structured, "SGML-like" syntax
573 grs.regx.<filter> structured, Regular expression filter
574 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
575 is the name of an abstract syntax file.
576 Bug fix: Result sets weren't sorted in operations involving boolean
577 operations with "ranked" operands.
581 Added national character-handling subsystem.
585 Small modifications to input filters and profiles.
587 Added support for SOIF syntax (with private OID).
591 Fixed buffer-size problem in indexing.
593 Added compression to temporary files for updating.
595 Added phrase registers.
597 Added dynamic mapping of search attribute to multiple termlists (ANY).
599 Scan support in multiple databases/registers.
601 Configuration settings are case-insensitive and single dash (-)
602 characters are ignored in comparisons.
604 The index processing ignores empty files - warning given.
606 New option to zebraidx (-V) displays version information.
610 Fixed problem in file-update system.
612 Fixed problem in shadow system; register was sometimes corrupted after
617 Fixed problems in the ISAM subsystem. Caused difficulties when updating
620 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
621 the rank and record number.
623 Fixed bug in the isam subsystem - caused a malfunction when accessing
624 words which occurred more than 10000 times.
626 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
629 Server can now run under inetd. Use option -i, and -w <directory> to
630 set working directory to desired location.
632 New zebraidx command: clean - removes temporary shadow files.
634 Fixed bug in ISAM system. Occurred rarely during register updates.
636 Logging during index merge phase is improved. The remaining running
639 Temporary files generated by zebraidx are removed after each run.
641 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
642 when doing scan operations in dictionaries with European characters.
646 A whole slew of updates, to make the first publicized release. Get the doc
651 Memory-problems in ISAM fixed. More blocktypes added to the default setup
652 to increase performance on larger databases.
654 Various minor changes in data management system.
658 A couple of portability-problems resolved.
660 Changed some malloc() to xmalloc().
