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

120 Fix bug in regx filter to make it "greedy" again. This bug appeared
125 --- 1.3.12 2003/09/08
127 Fix XML error handling. Stop XML parse immediately if XML parse error
128 occur (i.e. produce one error only).
130 Zebra ignores "unsupported use attribute" for individual databases
131 when search multiple databases (unless all databases fail).
133 New filter grs.marcxml which works like grs.marc but produces MARCXML.
135 Added support for database deletion. It is possible to create/drop
136 a database from zebraidx utility. Note: only for isam:b.
138 Write zebrasrv.pid to lockdir.
140 Bug fix: result sets were not recovered correctly. Had to
141 add ODR handle for zebra_search_RPN in order to make it work.
143 Fixed a bug in regx filters that didn't do anchors (^) correctly.
145 Fixed a bug in searches with X-Path searches sometimes giving "extra"
148 Zebra server checks for zebrasrv.pid and refuses to start if it is already
149 locked by another (running) zebrasrv.
151 Fixed a bug with text being chunked in pieces for the grs.xml filter.
153 --- 1.3.11 2003/04/25
155 xelm code updates. xelm works regardless state of 'xpath enable/disable'
156 Avoid -L/usr/lib since that is already default library path.
158 Allow multiple updates within one transaction.

162 --- 1.3.10 2003/04/01
164 Fix linker error for Perl module.
166 Fix bug in and operation which in some cases could result in "extra"
167 hits. Bug was introduced in 1.3.5.
169 Fix bug in handling of schema conversion when producing numeric tags.
175 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
179 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
180 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
181 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
183 livrank: another experimental ranking algorithm. Source in livcode.c.
184 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
186 Contributed by Pete Mallinson, University of Liverpool.
188 Advanced MARC indexing. See doc/marc_indexing.xml
189 Oleg Kolobov <oleg at lib.tpu.ru>
191 Perl API updates and fixes.
192 Peter Popovics <pop at technomat.hu>
194 Fixed 'zebraidx delete'.
196 Implemented 'zebraidx clean'.
198 64-bit offsets for register files on WIN32 (no 2 GB limit).
200 Fixed a few memory leaks WRT sorting.
204 Fixed error handling : error code was not properly returned.
206 Support Truncation 104 (CCL).
210 Added missing source files for perl extension.
214 Implemented xelm directive.
216 Updated for newer version of YAZ (introduction of string schema).
218 Directory examples/zthes now part of distribution (was missing
219 in previous release).
221 New .abs directive, systag, that control where to put retrieval
222 information. The directive takes two arguments: system tag, element name.
223 System tag is one of : rank, sysno, size.
227 Perl Filter and Perl API. By Peter Popovics.
229 For zebra.cfg, if no profilePath is specified, directory
230 (prefix)/share/idzebra/tab
233 Zebra Examples in examples . Zebra tests in test.
235 Bug fix: sort index was not properly modified on
236 record updates/deletes.
238 Fix handling of character entities for sgml filter.
240 Move data1 to Zebra (used to be part of YAZ).
244 Fix character encoding of scan response terms.
246 Fix character decoding of scan request terms.
248 Fix ESpec handling (requires YAZ 1.9.1)
250 Fix searches for complete fields.
254 When name zebra is used in a filename or directory 'idzebra' is used
255 instead to avoid confusion with GNU zebra (routing software).
257 Zebra server stops with a fatal error if config file cannot be read.
259 New config setting, followLinks, that controls whether update of files
260 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
261 By default symbolic links are followed.
263 Fix MARC transfer . MARC fields had wrong data for multiple fields.
265 XML record reader moved from YAZ to Zebra, to make YAZ less
266 dependant on external libraries.
268 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
269 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
270 on systems that doesn't offer iconv.
272 XML record reader supports external system entities.
276 New .abs-directive "xpath" that takes one argument: "enable"
277 or "disable" to enable and disable XPath -indexing. If no "xpath"
278 direcive is found in .abs-file , XPath-indexing is disabled to ensure
279 backwards compatibility. For missing .abs-files XPath-indexing is
280 enabled so that such records are searchable.
282 Zebra warns about missing .abs-file only once (for each type).
284 Fixed a bug in file update where already-inserted files could
289 Zebra license changed to GNU GPL.
291 XPath-like queries used when RPN string attributes are used, eg.
292 @attr 1=/portal/title sometitle
293 @attr 1=/portal/title[@xml:lang=da] danishtitle
294 @attr 1=/portal/title/@xml:lang da
295 @attr 1=//title sometitle
297 Zebra uses UTF-8 internally:
298 1) New setting "encoding" for zebra.cfg that specifies encoding for
299 OCTET terms in queries and record encoding for most transfer syntaxes
300 (except those that use International Strings, such as GRS-1).
301 2) The encoding of International strings is UTF-8 by default. It
302 may be changed by character set negotiation. If character set
303 negotiation is in effect and if records are selected for conversion
304 these'll be converted to the selected character set - thus overriding
305 the encoding setting in zebra.cfg.
306 3) New directive "encoding" in .abs-files. This specifies the external
307 character encoding for files indexed by zebra. However, if records
308 themselves have an XML header that specifies and encoding that'll be used
311 XML filter (-t grs.xml).
313 Multiple registers. New setting in resource 'root' that holds base
314 directory for register(s). A group a databases may be put in separate
315 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
319 Fixes for Digital Unix
321 Implemented hits per term using USR:SearchResult-1.
323 New Zebra API. Locking system re-implemented.
325 --- 1.1.stable 2002/02/20
327 Rank weight can be controlled with attribute type 9. Default
328 value is 34. Recommended values between 1-36.
332 Updated for YAZ version 1.8.
334 Added support for termsets - a result set of terms matching
335 a given query. For @attr 8=<set> creates termset named <set>.
337 Added support for raw retrieval. Element Set Name R forces the
338 text filter which returns the record in its original form.
340 Added numerical sort - triggered by structure=numeric (4=109).
342 Remote record import using Z39.50 Extended Services and Segments.
344 Fixed bug where updating a database with user-defined attributes
345 could corrupt the register (bad storeKeys).
347 Multi-threaded version.
349 Fixed bug regarding proximity.
351 Documentation updates.
353 Fixed bug in record retrieval module that occured on 64-bit OSF
358 Fixed bug in makefile for WIN32.
360 Fixed bug in configure script - used bash-specific features.
364 Added support for multiple records in one file for filter grs.sgml.
366 Changed record index structure. New layout is incompatible with
367 previous releases. Added setting "recordcompression" to control
368 compression of records. Possible values are "none" (no
369 compression) and bzip2 (compression using libbz2).
371 Added XML transfer syntax support for retrieval of structured records.
372 Schema in CompSpec is recognised in retrieval of structured records.
374 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
375 that fails, the filter reads the file <filt>.flt (regx style filter).
377 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
378 Zebra's configure script automatically attempts to locate Tcl. For
379 manual Tcl configuration use option --with-tclconfig=<path> to specify
380 where Tcl's library files are located.
382 Implemented "compression" of Dictionary and ISAM system. Dictionary
385 Added "tagsysno" directive to zebra.cfg to control under which tag the
386 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
389 Added "tagrank" as above.
391 Changed file naming scheme for register files from <name>.mf.<no> to
394 Implemented "position"-flag for register type (as defined in
395 default.idx). When set to zero no position (or seqence number) is
396 saved in register for each word occurrence, thus saving some register
399 Implemented database mapping. Using mapdb one can specify a database
400 to be mapped to one or more physical databases. Usage:
401 mapdb <fromdb> <todb> ..
403 Added SOIF-filter. Thanks to Peter Valkenburg.
405 For the regx-filter "end element -record" may trigger a mark-of-record
406 if outer level is reached.
408 Tag sets may be typed in the reference to it. From the .abs-file the
409 "tagset" directive takes a third optional integer type for the tag set
410 referenced. From a .tag-file the "include" directive takes a third
411 optional type as well. The old "type" directive in the tag set itself
412 is still recognized but acts as the default type for the tag set.
414 Zebra supports the specification of arbitrary attributes sets, schemas
415 and tag sets, because of the change in YAZ' OID management system.
417 Fixed bug in Sort that caused it NOT to use character mapping as it
420 Zebra now uses GNU configure to generate Makefile(s).
422 Added un-optimised support for left and left/right truncation attributes.
424 Added support for relational operators on text when using RPN queries.
426 Added support for sort specifications in RPN queries. Type 7 specifies
427 'sort' where value 1=ascending, value 2=descending. The use attribute
428 specifies the field criteria as usual. The term specifies priority
429 where 0=first, 1=second, ...
431 Changed the way use attributes are specified in the recordId
434 Maximum number of databases in one Zebra register increased.
436 New setting, databasePath, which specifies that first directory during
437 update traversal is the database name (instead of a fixed one).
439 New setting, explainDatabase, which specifies that databases are
442 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
444 Implemented EXPLAIN database maintenance. Zebra automatically
445 generate - and update CategoryList, TargetInfo, DatabaseInfo,
446 AttributeSetInfo and AttributeDetails records at this stage. The
447 records may be transferred as GRS-1, SUTRS or Explain.
449 Fixed register spec so that colon isn't treated as size separator
450 unless followed by [0-9+-] in order to allow DOS drive specifications.
452 Fixed two bugs in ISAMC system.
454 Changed the way Zebra keeps its maintenance information about attribute
455 sets, available attributes, etc.. Records in "SGML" notation using an
456 EXPLAIN schema is now used when appropriate.
458 Bug fix: Index didn't handle update/insert/delete of the same record
459 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
460 first occurence of a record is considered.
462 Most searches now return correct number of hits.
464 New modular ranking system. Interested programmers are encouraged to
465 inspect rank1.c and improve the algorithm.
467 Bug fix: Lock files weren't removed as they should on NT.
469 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
470 specify a "sort register". Refer to the gils sample records which refer
471 to index type "s" which is specified as "sort" in the default.idx file.
472 Each sort criteria can either be Ascending or Descending and at most
473 three sort elements can be specified.
475 Bug fix: Character mapping didn't work for text files.
479 Simple ranked searches now return correct number of hits.
481 The test option (-s) only makes a read-lock on the index as well
482 as using read-only operations anywhere.
484 Moved towards generic character mapping. Configuration file default.idx
485 specifies character map files for register types w, p, u, etc.
487 Implemented "begin variant" for the sgml.regx - filter.
489 Fixed a few memory leaks.
491 Added support for C++, headers uses extern "C" for public definitions.
493 Bug fix: The show records facility (-s) only displayed information for
494 the first record in a file (and not for every record in the file).
496 Added option "-f <n>" to limit the logging of record operations. After
497 <n> records has been processed no logging is performed (unless errors
500 Bug fix: the compressed ISAM system didn't handle update operations
503 Added setting, "maxResultSetSize", to hold the number of records to
504 save in a result set.
506 Bug fix: Complete phrase did't work for search operations.
508 Bug fix: temporary result sets weren't deleted.
510 Reduced disk space for saved keys (storeKeys = 1).
512 Added optional, physical ANY (key replication)
514 Implemented proximity operator in search.
516 Bug fix: the path name buffers used by file match traversal routines
517 have been extended to support long file names.
519 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
520 configuration file. The resulting register without "storeKeys" is about
521 half the size, and the memory used by zebraidx during phase 2 (merge) is
522 reduced to a minimum.
524 Reworked the way Regexp-2 queries with error tolerance are handled and
525 specified. The documentation has been updated accordingly.
527 Bug fix: Zebrasrv didn't search correctly when queries contained masking
528 characters. This bug was introduced in 1.0a8.
530 Zebrasrv now tag records with the proper database name.
532 New settings, memMax and keyTmpDir.
534 Changed name of setting lockDir (previously called lockPath) and
535 setTmpDir (previously called tempSetPath).
537 Generalized and changed record type specifications. In short, there are:
539 grs.sgml structured, "SGML-like" syntax
540 grs.regx.<filter> structured, Regular expression filter
541 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
542 is the name of an abstract syntax file.
543 Bug fix: Result sets weren't sorted in operations involving boolean
544 operations with "ranked" operands.
548 Added national character-handling subsystem.
552 Small modifications to input filters and profiles.
554 Added support for SOIF syntax (with private OID).
558 Fixed buffer-size problem in indexing.
560 Added compression to temporary files for updating.
562 Added phrase registers.
564 Added dynamic mapping of search attribute to multiple termlists (ANY).
566 Scan support in multiple databases/registers.
568 Configuration settings are case-insensitive and single dash (-)
569 characters are ignored in comparisons.
571 The index processing ignores empty files - warning given.
573 New option to zebraidx (-V) displays version information.
577 Fixed problem in file-update system.
579 Fixed problem in shadow system; register was sometimes corrupted after
584 Fixed problems in the ISAM subsystem. Caused difficulties when updating
587 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
588 the rank and record number.
590 Fixed bug in the isam subsystem - caused a malfunction when accessing
591 words which occurred more than 10000 times.
593 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
596 Server can now run under inetd. Use option -i, and -w <directory> to
597 set working directory to desired location.
599 New zebraidx command: clean - removes temporary shadow files.
601 Fixed bug in ISAM system. Occurred rarely during register updates.
603 Logging during index merge phase is improved. The remaining running
606 Temporary files generated by zebraidx are removed after each run.
608 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
609 when doing scan operations in dictionaries with European characters.
613 A whole slew of updates, to make the first publicized release. Get the doc
618 Memory-problems in ISAM fixed. More blocktypes added to the default setup
619 to increase performance on larger databases.
621 Various minor changes in data management system.
625 A couple of portability-problems resolved.
627 Changed some malloc() to xmalloc().
