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

118 --- 1.3.13 2003/09/26
120 Add missing examples for Windows install.
122 Fix bug in regx filter to make it "greedy" again. This bug appeared
127 --- 1.3.12 2003/09/08
129 Fix XML error handling. Stop XML parse immediately if XML parse error
130 occur (i.e. produce one error only).
132 Zebra ignores "unsupported use attribute" for individual databases
133 when search multiple databases (unless all databases fail).
135 New filter grs.marcxml which works like grs.marc but produces MARCXML.
137 Added support for database deletion. It is possible to create/drop
138 a database from zebraidx utility. Note: only for isam:b.
140 Write zebrasrv.pid to lockdir.
142 Bug fix: result sets were not recovered correctly. Had to
143 add ODR handle for zebra_search_RPN in order to make it work.
145 Fixed a bug in regx filters that didn't do anchors (^) correctly.
147 Fixed a bug in searches with X-Path searches sometimes giving "extra"
150 Zebra server checks for zebrasrv.pid and refuses to start if it is already
151 locked by another (running) zebrasrv.
153 Fixed a bug with text being chunked in pieces for the grs.xml filter.
155 --- 1.3.11 2003/04/25
157 xelm code updates. xelm works regardless state of 'xpath enable/disable'
158 Avoid -L/usr/lib since that is already default library path.
160 Allow multiple updates within one transaction.
162 Fixed a bug with >2GB files (overflow in integer expression).
164 --- 1.3.10 2003/04/01
166 Fix linker error for Perl module.
168 Fix bug in and operation which in some cases could result in "extra"
169 hits. Bug was introduced in 1.3.5.
171 Fix bug in handling of schema conversion when producing numeric tags.
177 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
181 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
182 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
183 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
185 livrank: another experimental ranking algorithm. Source in livcode.c.
186 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
188 Contributed by Pete Mallinson, University of Liverpool.
190 Advanced MARC indexing. See doc/marc_indexing.xml
191 Oleg Kolobov <oleg at lib.tpu.ru>
193 Perl API updates and fixes.
194 Peter Popovics <pop at technomat.hu>
196 Fixed 'zebraidx delete'.
198 Implemented 'zebraidx clean'.
200 64-bit offsets for register files on WIN32 (no 2 GB limit).
202 Fixed a few memory leaks WRT sorting.
206 Fixed error handling : error code was not properly returned.
208 Support Truncation 104 (CCL).
212 Added missing source files for perl extension.
216 Implemented xelm directive.
218 Updated for newer version of YAZ (introduction of string schema).
220 Directory examples/zthes now part of distribution (was missing
221 in previous release).
223 New .abs directive, systag, that control where to put retrieval
224 information. The directive takes two arguments: system tag, element name.
225 System tag is one of : rank, sysno, size.
229 Perl Filter and Perl API. By Peter Popovics.
231 For zebra.cfg, if no profilePath is specified, directory
232 (prefix)/share/idzebra/tab
235 Zebra Examples in examples . Zebra tests in test.
237 Bug fix: sort index was not properly modified on
238 record updates/deletes.
240 Fix handling of character entities for sgml filter.
242 Move data1 to Zebra (used to be part of YAZ).
246 Fix character encoding of scan response terms.
248 Fix character decoding of scan request terms.
250 Fix ESpec handling (requires YAZ 1.9.1)
252 Fix searches for complete fields.
256 When name zebra is used in a filename or directory 'idzebra' is used
257 instead to avoid confusion with GNU zebra (routing software).
259 Zebra server stops with a fatal error if config file cannot be read.
261 New config setting, followLinks, that controls whether update of files
262 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
263 By default symbolic links are followed.
265 Fix MARC transfer . MARC fields had wrong data for multiple fields.
267 XML record reader moved from YAZ to Zebra, to make YAZ less
268 dependant on external libraries.
270 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
271 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
272 on systems that doesn't offer iconv.
274 XML record reader supports external system entities.
278 New .abs-directive "xpath" that takes one argument: "enable"
279 or "disable" to enable and disable XPath -indexing. If no "xpath"
280 direcive is found in .abs-file , XPath-indexing is disabled to ensure
281 backwards compatibility. For missing .abs-files XPath-indexing is
282 enabled so that such records are searchable.
284 Zebra warns about missing .abs-file only once (for each type).
286 Fixed a bug in file update where already-inserted files could
291 Zebra license changed to GNU GPL.
293 XPath-like queries used when RPN string attributes are used, eg.
294 @attr 1=/portal/title sometitle
295 @attr 1=/portal/title[@xml:lang=da] danishtitle
296 @attr 1=/portal/title/@xml:lang da
297 @attr 1=//title sometitle
299 Zebra uses UTF-8 internally:
300 1) New setting "encoding" for zebra.cfg that specifies encoding for
301 OCTET terms in queries and record encoding for most transfer syntaxes
302 (except those that use International Strings, such as GRS-1).
303 2) The encoding of International strings is UTF-8 by default. It
304 may be changed by character set negotiation. If character set
305 negotiation is in effect and if records are selected for conversion
306 these'll be converted to the selected character set - thus overriding
307 the encoding setting in zebra.cfg.
308 3) New directive "encoding" in .abs-files. This specifies the external
309 character encoding for files indexed by zebra. However, if records
310 themselves have an XML header that specifies and encoding that'll be used
313 XML filter (-t grs.xml).
315 Multiple registers. New setting in resource 'root' that holds base
316 directory for register(s). A group a databases may be put in separate
317 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
321 Fixes for Digital Unix
323 Implemented hits per term using USR:SearchResult-1.
325 New Zebra API. Locking system re-implemented.
327 --- 1.1.stable 2002/02/20
329 Rank weight can be controlled with attribute type 9. Default
330 value is 34. Recommended values between 1-36.
334 Updated for YAZ version 1.8.
336 Added support for termsets - a result set of terms matching
337 a given query. For @attr 8=<set> creates termset named <set>.
339 Added support for raw retrieval. Element Set Name R forces the
340 text filter which returns the record in its original form.
342 Added numerical sort - triggered by structure=numeric (4=109).
344 Remote record import using Z39.50 Extended Services and Segments.
346 Fixed bug where updating a database with user-defined attributes
347 could corrupt the register (bad storeKeys).
349 Multi-threaded version.
351 Fixed bug regarding proximity.
353 Documentation updates.
355 Fixed bug in record retrieval module that occured on 64-bit OSF
360 Fixed bug in makefile for WIN32.
362 Fixed bug in configure script - used bash-specific features.
366 Added support for multiple records in one file for filter grs.sgml.
368 Changed record index structure. New layout is incompatible with
369 previous releases. Added setting "recordcompression" to control
370 compression of records. Possible values are "none" (no
371 compression) and bzip2 (compression using libbz2).
373 Added XML transfer syntax support for retrieval of structured records.
374 Schema in CompSpec is recognised in retrieval of structured records.
376 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
377 that fails, the filter reads the file <filt>.flt (regx style filter).
379 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
380 Zebra's configure script automatically attempts to locate Tcl. For
381 manual Tcl configuration use option --with-tclconfig=<path> to specify
382 where Tcl's library files are located.
384 Implemented "compression" of Dictionary and ISAM system. Dictionary
387 Added "tagsysno" directive to zebra.cfg to control under which tag the
388 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
391 Added "tagrank" as above.
393 Changed file naming scheme for register files from <name>.mf.<no> to
396 Implemented "position"-flag for register type (as defined in
397 default.idx). When set to zero no position (or seqence number) is
398 saved in register for each word occurrence, thus saving some register
401 Implemented database mapping. Using mapdb one can specify a database
402 to be mapped to one or more physical databases. Usage:
403 mapdb <fromdb> <todb> ..
405 Added SOIF-filter. Thanks to Peter Valkenburg.
407 For the regx-filter "end element -record" may trigger a mark-of-record
408 if outer level is reached.
410 Tag sets may be typed in the reference to it. From the .abs-file the
411 "tagset" directive takes a third optional integer type for the tag set
412 referenced. From a .tag-file the "include" directive takes a third
413 optional type as well. The old "type" directive in the tag set itself
414 is still recognized but acts as the default type for the tag set.
416 Zebra supports the specification of arbitrary attributes sets, schemas
417 and tag sets, because of the change in YAZ' OID management system.
419 Fixed bug in Sort that caused it NOT to use character mapping as it
422 Zebra now uses GNU configure to generate Makefile(s).
424 Added un-optimised support for left and left/right truncation attributes.
426 Added support for relational operators on text when using RPN queries.
428 Added support for sort specifications in RPN queries. Type 7 specifies
429 'sort' where value 1=ascending, value 2=descending. The use attribute
430 specifies the field criteria as usual. The term specifies priority
431 where 0=first, 1=second, ...
433 Changed the way use attributes are specified in the recordId
436 Maximum number of databases in one Zebra register increased.
438 New setting, databasePath, which specifies that first directory during
439 update traversal is the database name (instead of a fixed one).
441 New setting, explainDatabase, which specifies that databases are
444 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
446 Implemented EXPLAIN database maintenance. Zebra automatically
447 generate - and update CategoryList, TargetInfo, DatabaseInfo,
448 AttributeSetInfo and AttributeDetails records at this stage. The
449 records may be transferred as GRS-1, SUTRS or Explain.
451 Fixed register spec so that colon isn't treated as size separator
452 unless followed by [0-9+-] in order to allow DOS drive specifications.
454 Fixed two bugs in ISAMC system.
456 Changed the way Zebra keeps its maintenance information about attribute
457 sets, available attributes, etc.. Records in "SGML" notation using an
458 EXPLAIN schema is now used when appropriate.
460 Bug fix: Index didn't handle update/insert/delete of the same record
461 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
462 first occurence of a record is considered.
464 Most searches now return correct number of hits.
466 New modular ranking system. Interested programmers are encouraged to
467 inspect rank1.c and improve the algorithm.
469 Bug fix: Lock files weren't removed as they should on NT.
471 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
472 specify a "sort register". Refer to the gils sample records which refer
473 to index type "s" which is specified as "sort" in the default.idx file.
474 Each sort criteria can either be Ascending or Descending and at most
475 three sort elements can be specified.
477 Bug fix: Character mapping didn't work for text files.
481 Simple ranked searches now return correct number of hits.
483 The test option (-s) only makes a read-lock on the index as well
484 as using read-only operations anywhere.
486 Moved towards generic character mapping. Configuration file default.idx
487 specifies character map files for register types w, p, u, etc.
489 Implemented "begin variant" for the sgml.regx - filter.
491 Fixed a few memory leaks.
493 Added support for C++, headers uses extern "C" for public definitions.
495 Bug fix: The show records facility (-s) only displayed information for
496 the first record in a file (and not for every record in the file).
498 Added option "-f <n>" to limit the logging of record operations. After
499 <n> records has been processed no logging is performed (unless errors
502 Bug fix: the compressed ISAM system didn't handle update operations
505 Added setting, "maxResultSetSize", to hold the number of records to
506 save in a result set.
508 Bug fix: Complete phrase did't work for search operations.
510 Bug fix: temporary result sets weren't deleted.
512 Reduced disk space for saved keys (storeKeys = 1).
514 Added optional, physical ANY (key replication)
516 Implemented proximity operator in search.
518 Bug fix: the path name buffers used by file match traversal routines
519 have been extended to support long file names.
521 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
522 configuration file. The resulting register without "storeKeys" is about
523 half the size, and the memory used by zebraidx during phase 2 (merge) is
524 reduced to a minimum.
526 Reworked the way Regexp-2 queries with error tolerance are handled and
527 specified. The documentation has been updated accordingly.
529 Bug fix: Zebrasrv didn't search correctly when queries contained masking
530 characters. This bug was introduced in 1.0a8.
532 Zebrasrv now tag records with the proper database name.
534 New settings, memMax and keyTmpDir.
536 Changed name of setting lockDir (previously called lockPath) and
537 setTmpDir (previously called tempSetPath).
539 Generalized and changed record type specifications. In short, there are:
541 grs.sgml structured, "SGML-like" syntax
542 grs.regx.<filter> structured, Regular expression filter
543 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
544 is the name of an abstract syntax file.
545 Bug fix: Result sets weren't sorted in operations involving boolean
546 operations with "ranked" operands.
550 Added national character-handling subsystem.
554 Small modifications to input filters and profiles.
556 Added support for SOIF syntax (with private OID).
560 Fixed buffer-size problem in indexing.
562 Added compression to temporary files for updating.
564 Added phrase registers.
566 Added dynamic mapping of search attribute to multiple termlists (ANY).
568 Scan support in multiple databases/registers.
570 Configuration settings are case-insensitive and single dash (-)
571 characters are ignored in comparisons.
573 The index processing ignores empty files - warning given.
575 New option to zebraidx (-V) displays version information.
579 Fixed problem in file-update system.
581 Fixed problem in shadow system; register was sometimes corrupted after
586 Fixed problems in the ISAM subsystem. Caused difficulties when updating
589 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
590 the rank and record number.
592 Fixed bug in the isam subsystem - caused a malfunction when accessing
593 words which occurred more than 10000 times.
595 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
598 Server can now run under inetd. Use option -i, and -w <directory> to
599 set working directory to desired location.
601 New zebraidx command: clean - removes temporary shadow files.
603 Fixed bug in ISAM system. Occurred rarely during register updates.
605 Logging during index merge phase is improved. The remaining running
608 Temporary files generated by zebraidx are removed after each run.
610 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
611 when doing scan operations in dictionaries with European characters.
615 A whole slew of updates, to make the first publicized release. Get the doc
620 Memory-problems in ISAM fixed. More blocktypes added to the default setup
621 to increase performance on larger databases.
623 Various minor changes in data management system.
627 A couple of portability-problems resolved.
629 Changed some malloc() to xmalloc().
