6 Fixed bug #248: hit counts in combinatoric (and) searches in specific ..
8 Fixed bug #245: Time for getting records changes a lot based on record
11 Fixed bug #235: weird x-path results.
13 Avoid crash in ISAMB when isamb_pp_open gets ISAMB_POS = 0. In
14 this case EOF (no entries) is signalled. It fixes problem with
15 terms being deleted. See bug #109.
17 Fixed bug #169: Phrase term counts does not work. The bug exists in
20 Added mechanism to ignore leading articles when doing full-field indexing,
21 based on the character map files. See the manual for further discussion.
25 Fixed bug in record management. Releasing blocks could result in
28 Fixed bug in isam:b. A tree split could result in a lost item.
32 Add IDZebra.i to dist so that Perl extension builds again.
36 Added facility to make attibutes in grs.regx and grs.tcl filter using the
37 data command with argument -attribute <name> . The content of data is
38 the value of the attribute. This command should be used inside a
39 begin element , end element section.
41 Update zebra.nsi to NSIS 2.
43 Added a new 'cut' directive to charmaps (.chr files) which specifies that
44 only characters after the cutting char should be indexed.
46 Update Perl internals so that it matches the current Zebra API.
47 The recordGroup structure is no longer available. A group of resources
48 can still be referenced by setting groupName=>.. in various methods.
50 Maximum number of records to be sorted in a result set can be
51 specified by setting "sortmax". Default is 1000.
53 Allow use of string use attributes for regular attribute sets. The
54 name matches the name given in the attribute set file. All strings
55 starting with / are considered X-Path as usual.
57 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
58 element for XML tree. It may only pop off if -record is given.
60 Added grs.danbib filter - for Danish Bibliographic Centre.
62 Rename CHANGELOG to NEWS.
64 For text filter, return only header if elementSetName=H . elementSetName=R
65 returns contents only. Other elementSetName returns both header+content.
67 Added test for charmap and rusmarc.
69 Added feature charmaps (.chr) so that characters may be specified in
72 Fixed problem with encoding directive for charmap(.chr) files.
74 Allow Remote insert/delete/replace/update with record, recordIdNumber
75 (sysno) and/or recordIdOpaque(user supplied record Id). If both
76 IDs are omitted internal record ID match is assumed (recordId: - in
81 Fix bug. X-Path attribute expressions with spaces in them now works.
83 Fix base address for MARC output.
87 Fix bug with shadow and result set handling.
89 Implement MARCXML to ISO2709 conversion.
93 Add missing examples for Windows install.
95 Fix bug in regx filter to make it "greedy" again. This bug appeared
100 --- 1.3.12 2003/09/08
102 Fix XML error handling. Stop XML parse immediately if XML parse error
103 occur (i.e. produce one error only).
105 Zebra ignores "unsupported use attribute" for individual databases
106 when search multiple databases (unless all databases fail).
108 New filter grs.marcxml which works like grs.marc but produces MARCXML.
110 Added support for database deletion. It is possible to create/drop
111 a database from zebraidx utility. Note: only for isam:b.
113 Write zebrasrv.pid to lockdir.
115 Bug fix: result sets were not recovered correctly. Had to
116 add ODR handle for zebra_search_RPN in order to make it work.
118 Fixed a bug in regx filters that didn't do anchors (^) correctly.
120 Fixed a bug in searches with X-Path searches sometimes giving "extra"
123 Zebra server checks for zebrasrv.pid and refuses to start if it is already
124 locked by another (running) zebrasrv.
126 Fixed a bug with text being chunked in pieces for the grs.xml filter.
128 --- 1.3.11 2003/04/25
130 xelm code updates. xelm works regardless state of 'xpath enable/disable'
131 Avoid -L/usr/lib since that is already default library path.
133 Allow multiple updates within one transaction.
135 Fixed a bug with >2GB files (overflow in integer expression).
137 --- 1.3.10 2003/04/01
139 Fix linker error for Perl module.
141 Fix bug in and operation which in some cases could result in "extra"
142 hits. Bug was introduced in 1.3.5.
144 Fix bug in handling of schema conversion when producing numeric tags.
150 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
154 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
155 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
156 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
158 livrank: another experimental ranking algorithm. Source in livcode.c.
159 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
161 Contributed by Pete Mallinson, University of Liverpool.
163 Advanced MARC indexing. See doc/marc_indexing.xml
164 Oleg Kolobov <oleg at lib.tpu.ru>
166 Perl API updates and fixes.
167 Peter Popovics <pop at technomat.hu>
169 Fixed 'zebraidx delete'.
171 Implemented 'zebraidx clean'.
173 64-bit offsets for register files on WIN32 (no 2 GB limit).
175 Fixed a few memory leaks WRT sorting.
179 Fixed error handling : error code was not properly returned.
181 Support Truncation 104 (CCL).
185 Added missing source files for perl extension.
189 Implemented xelm directive.
191 Updated for newer version of YAZ (introduction of string schema).
193 Directory examples/zthes now part of distribution (was missing
194 in previous release).
196 New .abs directive, systag, that control where to put retrieval
197 information. The directive takes two arguments: system tag, element name.
198 System tag is one of : rank, sysno, size.
202 Perl Filter and Perl API. By Peter Popovics.
204 For zebra.cfg, if no profilePath is specified, directory
205 (prefix)/share/idzebra/tab
208 Zebra Examples in examples . Zebra tests in test.
210 Bug fix: sort index was not properly modified on
211 record updates/deletes.
213 Fix handling of character entities for sgml filter.
215 Move data1 to Zebra (used to be part of YAZ).
219 Fix character encoding of scan response terms.
221 Fix character decoding of scan request terms.
223 Fix ESpec handling (requires YAZ 1.9.1)
225 Fix searches for complete fields.
229 When name zebra is used in a filename or directory 'idzebra' is used
230 instead to avoid confusion with GNU zebra (routing software).
232 Zebra server stops with a fatal error if config file cannot be read.
234 New config setting, followLinks, that controls whether update of files
235 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
236 By default symbolic links are followed.
238 Fix MARC transfer . MARC fields had wrong data for multiple fields.
240 XML record reader moved from YAZ to Zebra, to make YAZ less
241 dependant on external libraries.
243 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
244 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
245 on systems that doesn't offer iconv.
247 XML record reader supports external system entities.
251 New .abs-directive "xpath" that takes one argument: "enable"
252 or "disable" to enable and disable XPath -indexing. If no "xpath"
253 direcive is found in .abs-file , XPath-indexing is disabled to ensure
254 backwards compatibility. For missing .abs-files XPath-indexing is
255 enabled so that such records are searchable.
257 Zebra warns about missing .abs-file only once (for each type).
259 Fixed a bug in file update where already-inserted files could
264 Zebra license changed to GNU GPL.
266 XPath-like queries used when RPN string attributes are used, eg.
267 @attr 1=/portal/title sometitle
268 @attr 1=/portal/title[@xml:lang=da] danishtitle
269 @attr 1=/portal/title/@xml:lang da
270 @attr 1=//title sometitle
272 Zebra uses UTF-8 internally:
273 1) New setting "encoding" for zebra.cfg that specifies encoding for
274 OCTET terms in queries and record encoding for most transfer syntaxes
275 (except those that use International Strings, such as GRS-1).
276 2) The encoding of International strings is UTF-8 by default. It
277 may be changed by character set negotiation. If character set
278 negotiation is in effect and if records are selected for conversion
279 these'll be converted to the selected character set - thus overriding
280 the encoding setting in zebra.cfg.
281 3) New directive "encoding" in .abs-files. This specifies the external
282 character encoding for files indexed by zebra. However, if records
283 themselves have an XML header that specifies and encoding that'll be used
286 XML filter (-t grs.xml).
288 Multiple registers. New setting in resource 'root' that holds base
289 directory for register(s). A group a databases may be put in separate
290 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
294 Fixes for Digital Unix
296 Implemented hits per term using USR:SearchResult-1.
298 New Zebra API. Locking system re-implemented.
300 --- 1.1.stable 2002/02/20
302 Rank weight can be controlled with attribute type 9. Default
303 value is 34. Recommended values between 1-36.
307 Updated for YAZ version 1.8.
309 Added support for termsets - a result set of terms matching
310 a given query. For @attr 8=<set> creates termset named <set>.
312 Added support for raw retrieval. Element Set Name R forces the
313 text filter which returns the record in its original form.
315 Added numerical sort - triggered by structure=numeric (4=109).
317 Remote record import using Z39.50 Extended Services and Segments.
319 Fixed bug where updating a database with user-defined attributes
320 could corrupt the register (bad storeKeys).
322 Multi-threaded version.
324 Fixed bug regarding proximity.
326 Documentation updates.
328 Fixed bug in record retrieval module that occured on 64-bit OSF
333 Fixed bug in makefile for WIN32.
335 Fixed bug in configure script - used bash-specific features.
339 Added support for multiple records in one file for filter grs.sgml.
341 Changed record index structure. New layout is incompatible with
342 previous releases. Added setting "recordcompression" to control
343 compression of records. Possible values are "none" (no
344 compression) and bzip2 (compression using libbz2).
346 Added XML transfer syntax support for retrieval of structured records.
347 Schema in CompSpec is recognised in retrieval of structured records.
349 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
350 that fails, the filter reads the file <filt>.flt (regx style filter).
352 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
353 Zebra's configure script automatically attempts to locate Tcl. For
354 manual Tcl configuration use option --with-tclconfig=<path> to specify
355 where Tcl's library files are located.
357 Implemented "compression" of Dictionary and ISAM system. Dictionary
360 Added "tagsysno" directive to zebra.cfg to control under which tag the
361 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
364 Added "tagrank" as above.
366 Changed file naming scheme for register files from <name>.mf.<no> to
369 Implemented "position"-flag for register type (as defined in
370 default.idx). When set to zero no position (or seqence number) is
371 saved in register for each word occurrence, thus saving some register
374 Implemented database mapping. Using mapdb one can specify a database
375 to be mapped to one or more physical databases. Usage:
376 mapdb <fromdb> <todb> ..
378 Added SOIF-filter. Thanks to Peter Valkenburg.
380 For the regx-filter "end element -record" may trigger a mark-of-record
381 if outer level is reached.
383 Tag sets may be typed in the reference to it. From the .abs-file the
384 "tagset" directive takes a third optional integer type for the tag set
385 referenced. From a .tag-file the "include" directive takes a third
386 optional type as well. The old "type" directive in the tag set itself
387 is still recognized but acts as the default type for the tag set.
389 Zebra supports the specification of arbitrary attributes sets, schemas
390 and tag sets, because of the change in YAZ' OID management system.
392 Fixed bug in Sort that caused it NOT to use character mapping as it
395 Zebra now uses GNU configure to generate Makefile(s).
397 Added un-optimised support for left and left/right truncation attributes.
399 Added support for relational operators on text when using RPN queries.
401 Added support for sort specifications in RPN queries. Type 7 specifies
402 'sort' where value 1=ascending, value 2=descending. The use attribute
403 specifies the field criteria as usual. The term specifies priority
404 where 0=first, 1=second, ...
406 Changed the way use attributes are specified in the recordId
409 Maximum number of databases in one Zebra register increased.
411 New setting, databasePath, which specifies that first directory during
412 update traversal is the database name (instead of a fixed one).
414 New setting, explainDatabase, which specifies that databases are
417 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
419 Implemented EXPLAIN database maintenance. Zebra automatically
420 generate - and update CategoryList, TargetInfo, DatabaseInfo,
421 AttributeSetInfo and AttributeDetails records at this stage. The
422 records may be transferred as GRS-1, SUTRS or Explain.
424 Fixed register spec so that colon isn't treated as size separator
425 unless followed by [0-9+-] in order to allow DOS drive specifications.
427 Fixed two bugs in ISAMC system.
429 Changed the way Zebra keeps its maintenance information about attribute
430 sets, available attributes, etc.. Records in "SGML" notation using an
431 EXPLAIN schema is now used when appropriate.
433 Bug fix: Index didn't handle update/insert/delete of the same record
434 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
435 first occurence of a record is considered.
437 Most searches now return correct number of hits.
439 New modular ranking system. Interested programmers are encouraged to
440 inspect rank1.c and improve the algorithm.
442 Bug fix: Lock files weren't removed as they should on NT.
444 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
445 specify a "sort register". Refer to the gils sample records which refer
446 to index type "s" which is specified as "sort" in the default.idx file.
447 Each sort criteria can either be Ascending or Descending and at most
448 three sort elements can be specified.
450 Bug fix: Character mapping didn't work for text files.
454 Simple ranked searches now return correct number of hits.
456 The test option (-s) only makes a read-lock on the index as well
457 as using read-only operations anywhere.
459 Moved towards generic character mapping. Configuration file default.idx
460 specifies character map files for register types w, p, u, etc.
462 Implemented "begin variant" for the sgml.regx - filter.
464 Fixed a few memory leaks.
466 Added support for C++, headers uses extern "C" for public definitions.
468 Bug fix: The show records facility (-s) only displayed information for
469 the first record in a file (and not for every record in the file).
471 Added option "-f <n>" to limit the logging of record operations. After
472 <n> records has been processed no logging is performed (unless errors
475 Bug fix: the compressed ISAM system didn't handle update operations
478 Added setting, "maxResultSetSize", to hold the number of records to
479 save in a result set.
481 Bug fix: Complete phrase did't work for search operations.
483 Bug fix: temporary result sets weren't deleted.
485 Reduced disk space for saved keys (storeKeys = 1).
487 Added optional, physical ANY (key replication)
489 Implemented proximity operator in search.
491 Bug fix: the path name buffers used by file match traversal routines
492 have been extended to support long file names.
494 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
495 configuration file. The resulting register without "storeKeys" is about
496 half the size, and the memory used by zebraidx during phase 2 (merge) is
497 reduced to a minimum.
499 Reworked the way Regexp-2 queries with error tolerance are handled and
500 specified. The documentation has been updated accordingly.
502 Bug fix: Zebrasrv didn't search correctly when queries contained masking
503 characters. This bug was introduced in 1.0a8.
505 Zebrasrv now tag records with the proper database name.
507 New settings, memMax and keyTmpDir.
509 Changed name of setting lockDir (previously called lockPath) and
510 setTmpDir (previously called tempSetPath).
512 Generalized and changed record type specifications. In short, there are:
514 grs.sgml structured, "SGML-like" syntax
515 grs.regx.<filter> structured, Regular expression filter
516 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
517 is the name of an abstract syntax file.
518 Bug fix: Result sets weren't sorted in operations involving boolean
519 operations with "ranked" operands.
523 Added national character-handling subsystem.
527 Small modifications to input filters and profiles.
529 Added support for SOIF syntax (with private OID).
533 Fixed buffer-size problem in indexing.
535 Added compression to temporary files for updating.
537 Added phrase registers.
539 Added dynamic mapping of search attribute to multiple termlists (ANY).
541 Scan support in multiple databases/registers.
543 Configuration settings are case-insensitive and single dash (-)
544 characters are ignored in comparisons.
546 The index processing ignores empty files - warning given.
548 New option to zebraidx (-V) displays version information.
552 Fixed problem in file-update system.
554 Fixed problem in shadow system; register was sometimes corrupted after
559 Fixed problems in the ISAM subsystem. Caused difficulties when updating
562 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
563 the rank and record number.
565 Fixed bug in the isam subsystem - caused a malfunction when accessing
566 words which occurred more than 10000 times.
568 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
571 Server can now run under inetd. Use option -i, and -w <directory> to
572 set working directory to desired location.
574 New zebraidx command: clean - removes temporary shadow files.
576 Fixed bug in ISAM system. Occurred rarely during register updates.
578 Logging during index merge phase is improved. The remaining running
581 Temporary files generated by zebraidx are removed after each run.
583 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
584 when doing scan operations in dictionaries with European characters.
588 A whole slew of updates, to make the first publicized release. Get the doc
593 Memory-problems in ISAM fixed. More blocktypes added to the default setup
594 to increase performance on larger databases.
596 Various minor changes in data management system.
600 A couple of portability-problems resolved.
602 Changed some malloc() to xmalloc().
