7 Fixed bug #248: hit counts in combinatoric (and) searches in specific ..
11 Fixed bug #248: hit counts in combinatoric (and) searches in specific ..
13 Fixed bug #245: Time for getting records changes a lot based on record
16 Fixed bug #235: weird x-path results.
18 Avoid crash in ISAMB when isamb_pp_open gets ISAMB_POS = 0. In
19 this case EOF (no entries) is signalled. It fixes problem with
20 terms being deleted. See bug #109.
22 Fixed bug #169: Phrase term counts does not work. The bug exists in
25 Added mechanism to ignore leading articles when doing full-field indexing,
26 based on the character map files. See the manual for further discussion.
30 Fixed bug in record management. Releasing blocks could result in
33 Fixed bug in isam:b. A tree split could result in a lost item.
37 Add IDZebra.i to dist so that Perl extension builds again.
41 Added facility to make attibutes in grs.regx and grs.tcl filter using the
42 data command with argument -attribute <name> . The content of data is
43 the value of the attribute. This command should be used inside a
44 begin element , end element section.
46 Update zebra.nsi to NSIS 2.
48 Added a new 'cut' directive to charmaps (.chr files) which specifies that
49 only characters after the cutting char should be indexed.
51 Update Perl internals so that it matches the current Zebra API.
52 The recordGroup structure is no longer available. A group of resources
53 can still be referenced by setting groupName=>.. in various methods.
55 Maximum number of records to be sorted in a result set can be
56 specified by setting "sortmax". Default is 1000.
58 Allow use of string use attributes for regular attribute sets. The
59 name matches the name given in the attribute set file. All strings
60 starting with / are considered X-Path as usual.
62 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
63 element for XML tree. It may only pop off if -record is given.
65 Added grs.danbib filter - for Danish Bibliographic Centre.
67 Rename CHANGELOG to NEWS.
69 For text filter, return only header if elementSetName=H . elementSetName=R
70 returns contents only. Other elementSetName returns both header+content.
72 Added test for charmap and rusmarc.
74 Added feature charmaps (.chr) so that characters may be specified in
77 Fixed problem with encoding directive for charmap(.chr) files.
79 Allow Remote insert/delete/replace/update with record, recordIdNumber
80 (sysno) and/or recordIdOpaque(user supplied record Id). If both
81 IDs are omitted internal record ID match is assumed (recordId: - in
86 Fix bug. X-Path attribute expressions with spaces in them now works.
88 Fix base address for MARC output.
92 Fix bug with shadow and result set handling.
94 Implement MARCXML to ISO2709 conversion.
98 Add missing examples for Windows install.
100 Fix bug in regx filter to make it "greedy" again. This bug appeared
105 --- 1.3.12 2003/09/08
107 Fix XML error handling. Stop XML parse immediately if XML parse error
108 occur (i.e. produce one error only).
110 Zebra ignores "unsupported use attribute" for individual databases
111 when search multiple databases (unless all databases fail).
113 New filter grs.marcxml which works like grs.marc but produces MARCXML.
115 Added support for database deletion. It is possible to create/drop
116 a database from zebraidx utility. Note: only for isam:b.
118 Write zebrasrv.pid to lockdir.
120 Bug fix: result sets were not recovered correctly. Had to
121 add ODR handle for zebra_search_RPN in order to make it work.
123 Fixed a bug in regx filters that didn't do anchors (^) correctly.
125 Fixed a bug in searches with X-Path searches sometimes giving "extra"
128 Zebra server checks for zebrasrv.pid and refuses to start if it is already
129 locked by another (running) zebrasrv.
131 Fixed a bug with text being chunked in pieces for the grs.xml filter.
133 --- 1.3.11 2003/04/25
135 xelm code updates. xelm works regardless state of 'xpath enable/disable'
136 Avoid -L/usr/lib since that is already default library path.
138 Allow multiple updates within one transaction.
140 Fixed a bug with >2GB files (overflow in integer expression).
142 --- 1.3.10 2003/04/01
144 Fix linker error for Perl module.
146 Fix bug in and operation which in some cases could result in "extra"
147 hits. Bug was introduced in 1.3.5.
149 Fix bug in handling of schema conversion when producing numeric tags.
155 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
159 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
160 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
161 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
163 livrank: another experimental ranking algorithm. Source in livcode.c.
164 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
166 Contributed by Pete Mallinson, University of Liverpool.
168 Advanced MARC indexing. See doc/marc_indexing.xml
169 Oleg Kolobov <oleg at lib.tpu.ru>
171 Perl API updates and fixes.
172 Peter Popovics <pop at technomat.hu>
174 Fixed 'zebraidx delete'.
176 Implemented 'zebraidx clean'.
178 64-bit offsets for register files on WIN32 (no 2 GB limit).
180 Fixed a few memory leaks WRT sorting.
184 Fixed error handling : error code was not properly returned.
186 Support Truncation 104 (CCL).
190 Added missing source files for perl extension.
194 Implemented xelm directive.
196 Updated for newer version of YAZ (introduction of string schema).
198 Directory examples/zthes now part of distribution (was missing
199 in previous release).
201 New .abs directive, systag, that control where to put retrieval
202 information. The directive takes two arguments: system tag, element name.
203 System tag is one of : rank, sysno, size.
207 Perl Filter and Perl API. By Peter Popovics.
209 For zebra.cfg, if no profilePath is specified, directory
210 (prefix)/share/idzebra/tab
213 Zebra Examples in examples . Zebra tests in test.
215 Bug fix: sort index was not properly modified on
216 record updates/deletes.
218 Fix handling of character entities for sgml filter.
220 Move data1 to Zebra (used to be part of YAZ).
224 Fix character encoding of scan response terms.
226 Fix character decoding of scan request terms.
228 Fix ESpec handling (requires YAZ 1.9.1)
230 Fix searches for complete fields.
234 When name zebra is used in a filename or directory 'idzebra' is used
235 instead to avoid confusion with GNU zebra (routing software).
237 Zebra server stops with a fatal error if config file cannot be read.
239 New config setting, followLinks, that controls whether update of files
240 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
241 By default symbolic links are followed.
243 Fix MARC transfer . MARC fields had wrong data for multiple fields.
245 XML record reader moved from YAZ to Zebra, to make YAZ less
246 dependant on external libraries.
248 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
249 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
250 on systems that doesn't offer iconv.
252 XML record reader supports external system entities.
256 New .abs-directive "xpath" that takes one argument: "enable"
257 or "disable" to enable and disable XPath -indexing. If no "xpath"
258 direcive is found in .abs-file , XPath-indexing is disabled to ensure
259 backwards compatibility. For missing .abs-files XPath-indexing is
260 enabled so that such records are searchable.
262 Zebra warns about missing .abs-file only once (for each type).
264 Fixed a bug in file update where already-inserted files could
269 Zebra license changed to GNU GPL.
271 XPath-like queries used when RPN string attributes are used, eg.
272 @attr 1=/portal/title sometitle
273 @attr 1=/portal/title[@xml:lang=da] danishtitle
274 @attr 1=/portal/title/@xml:lang da
275 @attr 1=//title sometitle
277 Zebra uses UTF-8 internally:
278 1) New setting "encoding" for zebra.cfg that specifies encoding for
279 OCTET terms in queries and record encoding for most transfer syntaxes
280 (except those that use International Strings, such as GRS-1).
281 2) The encoding of International strings is UTF-8 by default. It
282 may be changed by character set negotiation. If character set
283 negotiation is in effect and if records are selected for conversion
284 these'll be converted to the selected character set - thus overriding
285 the encoding setting in zebra.cfg.
286 3) New directive "encoding" in .abs-files. This specifies the external
287 character encoding for files indexed by zebra. However, if records
288 themselves have an XML header that specifies and encoding that'll be used
291 XML filter (-t grs.xml).
293 Multiple registers. New setting in resource 'root' that holds base
294 directory for register(s). A group a databases may be put in separate
295 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
299 Fixes for Digital Unix
301 Implemented hits per term using USR:SearchResult-1.
303 New Zebra API. Locking system re-implemented.
305 --- 1.1.stable 2002/02/20
307 Rank weight can be controlled with attribute type 9. Default
308 value is 34. Recommended values between 1-36.
312 Updated for YAZ version 1.8.
314 Added support for termsets - a result set of terms matching
315 a given query. For @attr 8=<set> creates termset named <set>.
317 Added support for raw retrieval. Element Set Name R forces the
318 text filter which returns the record in its original form.
320 Added numerical sort - triggered by structure=numeric (4=109).
322 Remote record import using Z39.50 Extended Services and Segments.
324 Fixed bug where updating a database with user-defined attributes
325 could corrupt the register (bad storeKeys).
327 Multi-threaded version.
329 Fixed bug regarding proximity.
331 Documentation updates.
333 Fixed bug in record retrieval module that occured on 64-bit OSF
338 Fixed bug in makefile for WIN32.
340 Fixed bug in configure script - used bash-specific features.
344 Added support for multiple records in one file for filter grs.sgml.
346 Changed record index structure. New layout is incompatible with
347 previous releases. Added setting "recordcompression" to control
348 compression of records. Possible values are "none" (no
349 compression) and bzip2 (compression using libbz2).
351 Added XML transfer syntax support for retrieval of structured records.
352 Schema in CompSpec is recognised in retrieval of structured records.
354 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
355 that fails, the filter reads the file <filt>.flt (regx style filter).
357 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
358 Zebra's configure script automatically attempts to locate Tcl. For
359 manual Tcl configuration use option --with-tclconfig=<path> to specify
360 where Tcl's library files are located.
362 Implemented "compression" of Dictionary and ISAM system. Dictionary
365 Added "tagsysno" directive to zebra.cfg to control under which tag the
366 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
369 Added "tagrank" as above.
371 Changed file naming scheme for register files from <name>.mf.<no> to
374 Implemented "position"-flag for register type (as defined in
375 default.idx). When set to zero no position (or seqence number) is
376 saved in register for each word occurrence, thus saving some register
379 Implemented database mapping. Using mapdb one can specify a database
380 to be mapped to one or more physical databases. Usage:
381 mapdb <fromdb> <todb> ..
383 Added SOIF-filter. Thanks to Peter Valkenburg.
385 For the regx-filter "end element -record" may trigger a mark-of-record
386 if outer level is reached.
388 Tag sets may be typed in the reference to it. From the .abs-file the
389 "tagset" directive takes a third optional integer type for the tag set
390 referenced. From a .tag-file the "include" directive takes a third
391 optional type as well. The old "type" directive in the tag set itself
392 is still recognized but acts as the default type for the tag set.
394 Zebra supports the specification of arbitrary attributes sets, schemas
395 and tag sets, because of the change in YAZ' OID management system.
397 Fixed bug in Sort that caused it NOT to use character mapping as it
400 Zebra now uses GNU configure to generate Makefile(s).
402 Added un-optimised support for left and left/right truncation attributes.
404 Added support for relational operators on text when using RPN queries.
406 Added support for sort specifications in RPN queries. Type 7 specifies
407 'sort' where value 1=ascending, value 2=descending. The use attribute
408 specifies the field criteria as usual. The term specifies priority
409 where 0=first, 1=second, ...
411 Changed the way use attributes are specified in the recordId
414 Maximum number of databases in one Zebra register increased.
416 New setting, databasePath, which specifies that first directory during
417 update traversal is the database name (instead of a fixed one).
419 New setting, explainDatabase, which specifies that databases are
422 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
424 Implemented EXPLAIN database maintenance. Zebra automatically
425 generate - and update CategoryList, TargetInfo, DatabaseInfo,
426 AttributeSetInfo and AttributeDetails records at this stage. The
427 records may be transferred as GRS-1, SUTRS or Explain.
429 Fixed register spec so that colon isn't treated as size separator
430 unless followed by [0-9+-] in order to allow DOS drive specifications.
432 Fixed two bugs in ISAMC system.
434 Changed the way Zebra keeps its maintenance information about attribute
435 sets, available attributes, etc.. Records in "SGML" notation using an
436 EXPLAIN schema is now used when appropriate.
438 Bug fix: Index didn't handle update/insert/delete of the same record
439 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
440 first occurence of a record is considered.
442 Most searches now return correct number of hits.
444 New modular ranking system. Interested programmers are encouraged to
445 inspect rank1.c and improve the algorithm.
447 Bug fix: Lock files weren't removed as they should on NT.
449 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
450 specify a "sort register". Refer to the gils sample records which refer
451 to index type "s" which is specified as "sort" in the default.idx file.
452 Each sort criteria can either be Ascending or Descending and at most
453 three sort elements can be specified.
455 Bug fix: Character mapping didn't work for text files.
459 Simple ranked searches now return correct number of hits.
461 The test option (-s) only makes a read-lock on the index as well
462 as using read-only operations anywhere.
464 Moved towards generic character mapping. Configuration file default.idx
465 specifies character map files for register types w, p, u, etc.
467 Implemented "begin variant" for the sgml.regx - filter.
469 Fixed a few memory leaks.
471 Added support for C++, headers uses extern "C" for public definitions.
473 Bug fix: The show records facility (-s) only displayed information for
474 the first record in a file (and not for every record in the file).
476 Added option "-f <n>" to limit the logging of record operations. After
477 <n> records has been processed no logging is performed (unless errors
480 Bug fix: the compressed ISAM system didn't handle update operations
483 Added setting, "maxResultSetSize", to hold the number of records to
484 save in a result set.
486 Bug fix: Complete phrase did't work for search operations.
488 Bug fix: temporary result sets weren't deleted.
490 Reduced disk space for saved keys (storeKeys = 1).
492 Added optional, physical ANY (key replication)
494 Implemented proximity operator in search.
496 Bug fix: the path name buffers used by file match traversal routines
497 have been extended to support long file names.
499 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
500 configuration file. The resulting register without "storeKeys" is about
501 half the size, and the memory used by zebraidx during phase 2 (merge) is
502 reduced to a minimum.
504 Reworked the way Regexp-2 queries with error tolerance are handled and
505 specified. The documentation has been updated accordingly.
507 Bug fix: Zebrasrv didn't search correctly when queries contained masking
508 characters. This bug was introduced in 1.0a8.
510 Zebrasrv now tag records with the proper database name.
512 New settings, memMax and keyTmpDir.
514 Changed name of setting lockDir (previously called lockPath) and
515 setTmpDir (previously called tempSetPath).
517 Generalized and changed record type specifications. In short, there are:
519 grs.sgml structured, "SGML-like" syntax
520 grs.regx.<filter> structured, Regular expression filter
521 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
522 is the name of an abstract syntax file.
523 Bug fix: Result sets weren't sorted in operations involving boolean
524 operations with "ranked" operands.
528 Added national character-handling subsystem.
532 Small modifications to input filters and profiles.
534 Added support for SOIF syntax (with private OID).
538 Fixed buffer-size problem in indexing.
540 Added compression to temporary files for updating.
542 Added phrase registers.
544 Added dynamic mapping of search attribute to multiple termlists (ANY).
546 Scan support in multiple databases/registers.
548 Configuration settings are case-insensitive and single dash (-)
549 characters are ignored in comparisons.
551 The index processing ignores empty files - warning given.
553 New option to zebraidx (-V) displays version information.
557 Fixed problem in file-update system.
559 Fixed problem in shadow system; register was sometimes corrupted after
564 Fixed problems in the ISAM subsystem. Caused difficulties when updating
567 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
568 the rank and record number.
570 Fixed bug in the isam subsystem - caused a malfunction when accessing
571 words which occurred more than 10000 times.
573 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
576 Server can now run under inetd. Use option -i, and -w <directory> to
577 set working directory to desired location.
579 New zebraidx command: clean - removes temporary shadow files.
581 Fixed bug in ISAM system. Occurred rarely during register updates.
583 Logging during index merge phase is improved. The remaining running
586 Temporary files generated by zebraidx are removed after each run.
588 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
589 when doing scan operations in dictionaries with European characters.
593 A whole slew of updates, to make the first publicized release. Get the doc
598 Memory-problems in ISAM fixed. More blocktypes added to the default setup
599 to increase performance on larger databases.
601 Various minor changes in data management system.
605 A couple of portability-problems resolved.
607 Changed some malloc() to xmalloc().
