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

114 --- 1.3.13 2003/09/26
116 Add missing examples for Windows install.
118 Fix bug in regx filter to make it "greedy" again. This bug appeared
123 --- 1.3.12 2003/09/08
125 Fix XML error handling. Stop XML parse immediately if XML parse error
126 occur (i.e. produce one error only).
128 Zebra ignores "unsupported use attribute" for individual databases
129 when search multiple databases (unless all databases fail).
131 New filter grs.marcxml which works like grs.marc but produces MARCXML.
133 Added support for database deletion. It is possible to create/drop
134 a database from zebraidx utility. Note: only for isam:b.
136 Write zebrasrv.pid to lockdir.
138 Bug fix: result sets were not recovered correctly. Had to
139 add ODR handle for zebra_search_RPN in order to make it work.
141 Fixed a bug in regx filters that didn't do anchors (^) correctly.
143 Fixed a bug in searches with X-Path searches sometimes giving "extra"
146 Zebra server checks for zebrasrv.pid and refuses to start if it is already
147 locked by another (running) zebrasrv.
149 Fixed a bug with text being chunked in pieces for the grs.xml filter.
151 --- 1.3.11 2003/04/25
153 xelm code updates. xelm works regardless state of 'xpath enable/disable'
154 Avoid -L/usr/lib since that is already default library path.
156 Allow multiple updates within one transaction.
158 Fixed a bug with >2GB files (overflow in integer expression).
160 --- 1.3.10 2003/04/01
162 Fix linker error for Perl module.
164 Fix bug in and operation which in some cases could result in "extra"
165 hits. Bug was introduced in 1.3.5.
167 Fix bug in handling of schema conversion when producing numeric tags.
173 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
177 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
178 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
179 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
181 livrank: another experimental ranking algorithm. Source in livcode.c.
182 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
184 Contributed by Pete Mallinson, University of Liverpool.
186 Advanced MARC indexing. See doc/marc_indexing.xml
187 Oleg Kolobov <oleg at lib.tpu.ru>
189 Perl API updates and fixes.
190 Peter Popovics <pop at technomat.hu>
192 Fixed 'zebraidx delete'.
194 Implemented 'zebraidx clean'.
196 64-bit offsets for register files on WIN32 (no 2 GB limit).
198 Fixed a few memory leaks WRT sorting.
202 Fixed error handling : error code was not properly returned.
204 Support Truncation 104 (CCL).
208 Added missing source files for perl extension.
212 Implemented xelm directive.
214 Updated for newer version of YAZ (introduction of string schema).
216 Directory examples/zthes now part of distribution (was missing
217 in previous release).
219 New .abs directive, systag, that control where to put retrieval
220 information. The directive takes two arguments: system tag, element name.
221 System tag is one of : rank, sysno, size.
225 Perl Filter and Perl API. By Peter Popovics.
227 For zebra.cfg, if no profilePath is specified, directory
228 (prefix)/share/idzebra/tab
231 Zebra Examples in examples . Zebra tests in test.
233 Bug fix: sort index was not properly modified on
234 record updates/deletes.
236 Fix handling of character entities for sgml filter.
238 Move data1 to Zebra (used to be part of YAZ).
242 Fix character encoding of scan response terms.
244 Fix character decoding of scan request terms.
246 Fix ESpec handling (requires YAZ 1.9.1)
248 Fix searches for complete fields.
252 When name zebra is used in a filename or directory 'idzebra' is used
253 instead to avoid confusion with GNU zebra (routing software).
255 Zebra server stops with a fatal error if config file cannot be read.
257 New config setting, followLinks, that controls whether update of files
258 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
259 By default symbolic links are followed.
261 Fix MARC transfer . MARC fields had wrong data for multiple fields.
263 XML record reader moved from YAZ to Zebra, to make YAZ less
264 dependant on external libraries.
266 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
267 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
268 on systems that doesn't offer iconv.
270 XML record reader supports external system entities.
274 New .abs-directive "xpath" that takes one argument: "enable"
275 or "disable" to enable and disable XPath -indexing. If no "xpath"
276 direcive is found in .abs-file , XPath-indexing is disabled to ensure
277 backwards compatibility. For missing .abs-files XPath-indexing is
278 enabled so that such records are searchable.
280 Zebra warns about missing .abs-file only once (for each type).
282 Fixed a bug in file update where already-inserted files could
287 Zebra license changed to GNU GPL.
289 XPath-like queries used when RPN string attributes are used, eg.
290 @attr 1=/portal/title sometitle
291 @attr 1=/portal/title[@xml:lang=da] danishtitle
292 @attr 1=/portal/title/@xml:lang da
293 @attr 1=//title sometitle
295 Zebra uses UTF-8 internally:
296 1) New setting "encoding" for zebra.cfg that specifies encoding for
297 OCTET terms in queries and record encoding for most transfer syntaxes
298 (except those that use International Strings, such as GRS-1).
299 2) The encoding of International strings is UTF-8 by default. It
300 may be changed by character set negotiation. If character set
301 negotiation is in effect and if records are selected for conversion
302 these'll be converted to the selected character set - thus overriding
303 the encoding setting in zebra.cfg.
304 3) New directive "encoding" in .abs-files. This specifies the external
305 character encoding for files indexed by zebra. However, if records
306 themselves have an XML header that specifies and encoding that'll be used
309 XML filter (-t grs.xml).
311 Multiple registers. New setting in resource 'root' that holds base
312 directory for register(s). A group a databases may be put in separate
313 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
317 Fixes for Digital Unix
319 Implemented hits per term using USR:SearchResult-1.
321 New Zebra API. Locking system re-implemented.
323 --- 1.1.stable 2002/02/20
325 Rank weight can be controlled with attribute type 9. Default
326 value is 34. Recommended values between 1-36.
330 Updated for YAZ version 1.8.
332 Added support for termsets - a result set of terms matching
333 a given query. For @attr 8=<set> creates termset named <set>.
335 Added support for raw retrieval. Element Set Name R forces the
336 text filter which returns the record in its original form.
338 Added numerical sort - triggered by structure=numeric (4=109).
340 Remote record import using Z39.50 Extended Services and Segments.
342 Fixed bug where updating a database with user-defined attributes
343 could corrupt the register (bad storeKeys).
345 Multi-threaded version.
347 Fixed bug regarding proximity.
349 Documentation updates.
351 Fixed bug in record retrieval module that occured on 64-bit OSF
356 Fixed bug in makefile for WIN32.
358 Fixed bug in configure script - used bash-specific features.
362 Added support for multiple records in one file for filter grs.sgml.
364 Changed record index structure. New layout is incompatible with
365 previous releases. Added setting "recordcompression" to control
366 compression of records. Possible values are "none" (no
367 compression) and bzip2 (compression using libbz2).
369 Added XML transfer syntax support for retrieval of structured records.
370 Schema in CompSpec is recognised in retrieval of structured records.
372 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
373 that fails, the filter reads the file <filt>.flt (regx style filter).
375 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
376 Zebra's configure script automatically attempts to locate Tcl. For
377 manual Tcl configuration use option --with-tclconfig=<path> to specify
378 where Tcl's library files are located.
380 Implemented "compression" of Dictionary and ISAM system. Dictionary
383 Added "tagsysno" directive to zebra.cfg to control under which tag the
384 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
387 Added "tagrank" as above.
389 Changed file naming scheme for register files from <name>.mf.<no> to
392 Implemented "position"-flag for register type (as defined in
393 default.idx). When set to zero no position (or seqence number) is
394 saved in register for each word occurrence, thus saving some register
397 Implemented database mapping. Using mapdb one can specify a database
398 to be mapped to one or more physical databases. Usage:
399 mapdb <fromdb> <todb> ..
401 Added SOIF-filter. Thanks to Peter Valkenburg.
403 For the regx-filter "end element -record" may trigger a mark-of-record
404 if outer level is reached.
406 Tag sets may be typed in the reference to it. From the .abs-file the
407 "tagset" directive takes a third optional integer type for the tag set
408 referenced. From a .tag-file the "include" directive takes a third
409 optional type as well. The old "type" directive in the tag set itself
410 is still recognized but acts as the default type for the tag set.
412 Zebra supports the specification of arbitrary attributes sets, schemas
413 and tag sets, because of the change in YAZ' OID management system.
415 Fixed bug in Sort that caused it NOT to use character mapping as it
418 Zebra now uses GNU configure to generate Makefile(s).
420 Added un-optimised support for left and left/right truncation attributes.
422 Added support for relational operators on text when using RPN queries.
424 Added support for sort specifications in RPN queries. Type 7 specifies
425 'sort' where value 1=ascending, value 2=descending. The use attribute
426 specifies the field criteria as usual. The term specifies priority
427 where 0=first, 1=second, ...
429 Changed the way use attributes are specified in the recordId
432 Maximum number of databases in one Zebra register increased.
434 New setting, databasePath, which specifies that first directory during
435 update traversal is the database name (instead of a fixed one).
437 New setting, explainDatabase, which specifies that databases are
440 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
442 Implemented EXPLAIN database maintenance. Zebra automatically
443 generate - and update CategoryList, TargetInfo, DatabaseInfo,
444 AttributeSetInfo and AttributeDetails records at this stage. The
445 records may be transferred as GRS-1, SUTRS or Explain.
447 Fixed register spec so that colon isn't treated as size separator
448 unless followed by [0-9+-] in order to allow DOS drive specifications.
450 Fixed two bugs in ISAMC system.
452 Changed the way Zebra keeps its maintenance information about attribute
453 sets, available attributes, etc.. Records in "SGML" notation using an
454 EXPLAIN schema is now used when appropriate.
456 Bug fix: Index didn't handle update/insert/delete of the same record
457 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
458 first occurence of a record is considered.
460 Most searches now return correct number of hits.
462 New modular ranking system. Interested programmers are encouraged to
463 inspect rank1.c and improve the algorithm.
465 Bug fix: Lock files weren't removed as they should on NT.
467 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
468 specify a "sort register". Refer to the gils sample records which refer
469 to index type "s" which is specified as "sort" in the default.idx file.
470 Each sort criteria can either be Ascending or Descending and at most
471 three sort elements can be specified.
473 Bug fix: Character mapping didn't work for text files.
477 Simple ranked searches now return correct number of hits.
479 The test option (-s) only makes a read-lock on the index as well
480 as using read-only operations anywhere.
482 Moved towards generic character mapping. Configuration file default.idx
483 specifies character map files for register types w, p, u, etc.
485 Implemented "begin variant" for the sgml.regx - filter.
487 Fixed a few memory leaks.
489 Added support for C++, headers uses extern "C" for public definitions.
491 Bug fix: The show records facility (-s) only displayed information for
492 the first record in a file (and not for every record in the file).
494 Added option "-f <n>" to limit the logging of record operations. After
495 <n> records has been processed no logging is performed (unless errors
498 Bug fix: the compressed ISAM system didn't handle update operations
501 Added setting, "maxResultSetSize", to hold the number of records to
502 save in a result set.
504 Bug fix: Complete phrase did't work for search operations.
506 Bug fix: temporary result sets weren't deleted.
508 Reduced disk space for saved keys (storeKeys = 1).
510 Added optional, physical ANY (key replication)
512 Implemented proximity operator in search.
514 Bug fix: the path name buffers used by file match traversal routines
515 have been extended to support long file names.
517 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
518 configuration file. The resulting register without "storeKeys" is about
519 half the size, and the memory used by zebraidx during phase 2 (merge) is
520 reduced to a minimum.
522 Reworked the way Regexp-2 queries with error tolerance are handled and
523 specified. The documentation has been updated accordingly.
525 Bug fix: Zebrasrv didn't search correctly when queries contained masking
526 characters. This bug was introduced in 1.0a8.
528 Zebrasrv now tag records with the proper database name.
530 New settings, memMax and keyTmpDir.
532 Changed name of setting lockDir (previously called lockPath) and
533 setTmpDir (previously called tempSetPath).
535 Generalized and changed record type specifications. In short, there are:
537 grs.sgml structured, "SGML-like" syntax
538 grs.regx.<filter> structured, Regular expression filter
539 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
540 is the name of an abstract syntax file.
541 Bug fix: Result sets weren't sorted in operations involving boolean
542 operations with "ranked" operands.
546 Added national character-handling subsystem.
550 Small modifications to input filters and profiles.
552 Added support for SOIF syntax (with private OID).
556 Fixed buffer-size problem in indexing.
558 Added compression to temporary files for updating.
560 Added phrase registers.
562 Added dynamic mapping of search attribute to multiple termlists (ANY).
564 Scan support in multiple databases/registers.
566 Configuration settings are case-insensitive and single dash (-)
567 characters are ignored in comparisons.
569 The index processing ignores empty files - warning given.
571 New option to zebraidx (-V) displays version information.
575 Fixed problem in file-update system.
577 Fixed problem in shadow system; register was sometimes corrupted after
582 Fixed problems in the ISAM subsystem. Caused difficulties when updating
585 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
586 the rank and record number.
588 Fixed bug in the isam subsystem - caused a malfunction when accessing
589 words which occurred more than 10000 times.
591 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
594 Server can now run under inetd. Use option -i, and -w <directory> to
595 set working directory to desired location.
597 New zebraidx command: clean - removes temporary shadow files.
599 Fixed bug in ISAM system. Occurred rarely during register updates.
601 Logging during index merge phase is improved. The remaining running
604 Temporary files generated by zebraidx are removed after each run.
606 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
607 when doing scan operations in dictionaries with European characters.
611 A whole slew of updates, to make the first publicized release. Get the doc
616 Memory-problems in ISAM fixed. More blocktypes added to the default setup
617 to increase performance on larger databases.
619 Various minor changes in data management system.
623 A couple of portability-problems resolved.
625 Changed some malloc() to xmalloc().
