4 Fixed bug #169: Phrase term counts does not work. The bug exists in
7 Added mechanism to ignore leading articles when doing full-field indexing,
8 based on the character map files. See the manual for further discussion.
12 Fixed bug in record management. Releasing blocks could result in
15 Fixed bug in isam:b. A tree split could result in a lost item.
19 Add IDZebra.i to dist so that Perl extension builds again.
23 Added facility to make attibutes in grs.regx and grs.tcl filter using the
24 data command with argument -attribute <name> . The content of data is
25 the value of the attribute. This command should be used inside a
26 begin element , end element section.
28 Update zebra.nsi to NSIS 2.
30 Added a new 'cut' directive to charmaps (.chr files) which specifies that
31 only characters after the cutting char should be indexed.
33 Update Perl internals so that it matches the current Zebra API.
34 The recordGroup structure is no longer available. A group of resources
35 can still be referenced by setting groupName=>.. in various methods.
37 Maximum number of records to be sorted in a result set can be
38 specified by setting "sortmax". Default is 1000.
40 Allow use of string use attributes for regular attribute sets. The
41 name matches the name given in the attribute set file. All strings
42 starting with / are considered X-Path as usual.
44 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
45 element for XML tree. It may only pop off if -record is given.
47 Added grs.danbib filter - for Danish Bibliographic Centre.
49 Rename CHANGELOG to NEWS.
51 For text filter, return only header if elementSetName=H . elementSetName=R
52 returns contents only. Other elementSetName returns both header+content.
54 Added test for charmap and rusmarc.
56 Added feature charmaps (.chr) so that characters may be specified in
59 Fixed problem with encoding directive for charmap(.chr) files.
61 Allow Remote insert/delete/replace/update with record, recordIdNumber
62 (sysno) and/or recordIdOpaque(user supplied record Id). If both
63 IDs are omitted internal record ID match is assumed (recordId: - in
68 Fix bug. X-Path attribute expressions with spaces in them now works.
70 Fix base address for MARC output.
74 Fix bug with shadow and result set handling.
76 Implement MARCXML to ISO2709 conversion.
80 Add missing examples for Windows install.
82 Fix bug in regx filter to make it "greedy" again. This bug appeared
89 Fix XML error handling. Stop XML parse immediately if XML parse error
90 occur (i.e. produce one error only).
92 Zebra ignores "unsupported use attribute" for individual databases
93 when search multiple databases (unless all databases fail).
95 New filter grs.marcxml which works like grs.marc but produces MARCXML.
97 Added support for database deletion. It is possible to create/drop
98 a database from zebraidx utility. Note: only for isam:b.
100 Write zebrasrv.pid to lockdir.
102 Bug fix: result sets were not recovered correctly. Had to
103 add ODR handle for zebra_search_RPN in order to make it work.
105 Fixed a bug in regx filters that didn't do anchors (^) correctly.
107 Fixed a bug in searches with X-Path searches sometimes giving "extra"
110 Zebra server checks for zebrasrv.pid and refuses to start if it is already
111 locked by another (running) zebrasrv.
113 Fixed a bug with text being chunked in pieces for the grs.xml filter.
115 --- 1.3.11 2003/04/25
117 xelm code updates. xelm works regardless state of 'xpath enable/disable'
118 Avoid -L/usr/lib since that is already default library path.
120 Allow multiple updates within one transaction.
122 Fixed a bug with >2GB files (overflow in integer expression).
124 --- 1.3.10 2003/04/01
126 Fix linker error for Perl module.
128 Fix bug in and operation which in some cases could result in "extra"
129 hits. Bug was introduced in 1.3.5.
131 Fix bug in handling of schema conversion when producing numeric tags.
137 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
141 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
142 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
143 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
145 livrank: another experimental ranking algorithm. Source in livcode.c.
146 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
148 Contributed by Pete Mallinson, University of Liverpool.
150 Advanced MARC indexing. See doc/marc_indexing.xml
151 Oleg Kolobov <oleg at lib.tpu.ru>
153 Perl API updates and fixes.
154 Peter Popovics <pop at technomat.hu>
156 Fixed 'zebraidx delete'.
158 Implemented 'zebraidx clean'.
160 64-bit offsets for register files on WIN32 (no 2 GB limit).
162 Fixed a few memory leaks WRT sorting.
166 Fixed error handling : error code was not properly returned.
168 Support Truncation 104 (CCL).
172 Added missing source files for perl extension.
176 Implemented xelm directive.
178 Updated for newer version of YAZ (introduction of string schema).
180 Directory examples/zthes now part of distribution (was missing
181 in previous release).
183 New .abs directive, systag, that control where to put retrieval
184 information. The directive takes two arguments: system tag, element name.
185 System tag is one of : rank, sysno, size.
189 Perl Filter and Perl API. By Peter Popovics.
191 For zebra.cfg, if no profilePath is specified, directory
192 (prefix)/share/idzebra/tab
195 Zebra Examples in examples . Zebra tests in test.
197 Bug fix: sort index was not properly modified on
198 record updates/deletes.
200 Fix handling of character entities for sgml filter.
202 Move data1 to Zebra (used to be part of YAZ).
206 Fix character encoding of scan response terms.
208 Fix character decoding of scan request terms.
210 Fix ESpec handling (requires YAZ 1.9.1)
212 Fix searches for complete fields.
216 When name zebra is used in a filename or directory 'idzebra' is used
217 instead to avoid confusion with GNU zebra (routing software).
219 Zebra server stops with a fatal error if config file cannot be read.
221 New config setting, followLinks, that controls whether update of files
222 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
223 By default symbolic links are followed.
225 Fix MARC transfer . MARC fields had wrong data for multiple fields.
227 XML record reader moved from YAZ to Zebra, to make YAZ less
228 dependant on external libraries.
230 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
231 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
232 on systems that doesn't offer iconv.
234 XML record reader supports external system entities.
238 New .abs-directive "xpath" that takes one argument: "enable"
239 or "disable" to enable and disable XPath -indexing. If no "xpath"
240 direcive is found in .abs-file , XPath-indexing is disabled to ensure
241 backwards compatibility. For missing .abs-files XPath-indexing is
242 enabled so that such records are searchable.
244 Zebra warns about missing .abs-file only once (for each type).
246 Fixed a bug in file update where already-inserted files could
251 Zebra license changed to GNU GPL.
253 XPath-like queries used when RPN string attributes are used, eg.
254 @attr 1=/portal/title sometitle
255 @attr 1=/portal/title[@xml:lang=da] danishtitle
256 @attr 1=/portal/title/@xml:lang da
257 @attr 1=//title sometitle
259 Zebra uses UTF-8 internally:
260 1) New setting "encoding" for zebra.cfg that specifies encoding for
261 OCTET terms in queries and record encoding for most transfer syntaxes
262 (except those that use International Strings, such as GRS-1).
263 2) The encoding of International strings is UTF-8 by default. It
264 may be changed by character set negotiation. If character set
265 negotiation is in effect and if records are selected for conversion
266 these'll be converted to the selected character set - thus overriding
267 the encoding setting in zebra.cfg.
268 3) New directive "encoding" in .abs-files. This specifies the external
269 character encoding for files indexed by zebra. However, if records
270 themselves have an XML header that specifies and encoding that'll be used
273 XML filter (-t grs.xml).
275 Multiple registers. New setting in resource 'root' that holds base
276 directory for register(s). A group a databases may be put in separate
277 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
281 Fixes for Digital Unix
283 Implemented hits per term using USR:SearchResult-1.
285 New Zebra API. Locking system re-implemented.
287 --- 1.1.stable 2002/02/20
289 Rank weight can be controlled with attribute type 9. Default
290 value is 34. Recommended values between 1-36.
294 Updated for YAZ version 1.8.
296 Added support for termsets - a result set of terms matching
297 a given query. For @attr 8=<set> creates termset named <set>.
299 Added support for raw retrieval. Element Set Name R forces the
300 text filter which returns the record in its original form.
302 Added numerical sort - triggered by structure=numeric (4=109).
304 Remote record import using Z39.50 Extended Services and Segments.
306 Fixed bug where updating a database with user-defined attributes
307 could corrupt the register (bad storeKeys).
309 Multi-threaded version.
311 Fixed bug regarding proximity.
313 Documentation updates.
315 Fixed bug in record retrieval module that occured on 64-bit OSF
320 Fixed bug in makefile for WIN32.
322 Fixed bug in configure script - used bash-specific features.
326 Added support for multiple records in one file for filter grs.sgml.
328 Changed record index structure. New layout is incompatible with
329 previous releases. Added setting "recordcompression" to control
330 compression of records. Possible values are "none" (no
331 compression) and bzip2 (compression using libbz2).
333 Added XML transfer syntax support for retrieval of structured records.
334 Schema in CompSpec is recognised in retrieval of structured records.
336 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
337 that fails, the filter reads the file <filt>.flt (regx style filter).
339 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
340 Zebra's configure script automatically attempts to locate Tcl. For
341 manual Tcl configuration use option --with-tclconfig=<path> to specify
342 where Tcl's library files are located.
344 Implemented "compression" of Dictionary and ISAM system. Dictionary
347 Added "tagsysno" directive to zebra.cfg to control under which tag the
348 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
351 Added "tagrank" as above.
353 Changed file naming scheme for register files from <name>.mf.<no> to
356 Implemented "position"-flag for register type (as defined in
357 default.idx). When set to zero no position (or seqence number) is
358 saved in register for each word occurrence, thus saving some register
361 Implemented database mapping. Using mapdb one can specify a database
362 to be mapped to one or more physical databases. Usage:
363 mapdb <fromdb> <todb> ..
365 Added SOIF-filter. Thanks to Peter Valkenburg.
367 For the regx-filter "end element -record" may trigger a mark-of-record
368 if outer level is reached.
370 Tag sets may be typed in the reference to it. From the .abs-file the
371 "tagset" directive takes a third optional integer type for the tag set
372 referenced. From a .tag-file the "include" directive takes a third
373 optional type as well. The old "type" directive in the tag set itself
374 is still recognized but acts as the default type for the tag set.
376 Zebra supports the specification of arbitrary attributes sets, schemas
377 and tag sets, because of the change in YAZ' OID management system.
379 Fixed bug in Sort that caused it NOT to use character mapping as it
382 Zebra now uses GNU configure to generate Makefile(s).
384 Added un-optimised support for left and left/right truncation attributes.
386 Added support for relational operators on text when using RPN queries.
388 Added support for sort specifications in RPN queries. Type 7 specifies
389 'sort' where value 1=ascending, value 2=descending. The use attribute
390 specifies the field criteria as usual. The term specifies priority
391 where 0=first, 1=second, ...
393 Changed the way use attributes are specified in the recordId
396 Maximum number of databases in one Zebra register increased.
398 New setting, databasePath, which specifies that first directory during
399 update traversal is the database name (instead of a fixed one).
401 New setting, explainDatabase, which specifies that databases are
404 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
406 Implemented EXPLAIN database maintenance. Zebra automatically
407 generate - and update CategoryList, TargetInfo, DatabaseInfo,
408 AttributeSetInfo and AttributeDetails records at this stage. The
409 records may be transferred as GRS-1, SUTRS or Explain.
411 Fixed register spec so that colon isn't treated as size separator
412 unless followed by [0-9+-] in order to allow DOS drive specifications.
414 Fixed two bugs in ISAMC system.
416 Changed the way Zebra keeps its maintenance information about attribute
417 sets, available attributes, etc.. Records in "SGML" notation using an
418 EXPLAIN schema is now used when appropriate.
420 Bug fix: Index didn't handle update/insert/delete of the same record
421 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
422 first occurence of a record is considered.
424 Most searches now return correct number of hits.
426 New modular ranking system. Interested programmers are encouraged to
427 inspect rank1.c and improve the algorithm.
429 Bug fix: Lock files weren't removed as they should on NT.
431 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
432 specify a "sort register". Refer to the gils sample records which refer
433 to index type "s" which is specified as "sort" in the default.idx file.
434 Each sort criteria can either be Ascending or Descending and at most
435 three sort elements can be specified.
437 Bug fix: Character mapping didn't work for text files.
441 Simple ranked searches now return correct number of hits.
443 The test option (-s) only makes a read-lock on the index as well
444 as using read-only operations anywhere.
446 Moved towards generic character mapping. Configuration file default.idx
447 specifies character map files for register types w, p, u, etc.
449 Implemented "begin variant" for the sgml.regx - filter.
451 Fixed a few memory leaks.
453 Added support for C++, headers uses extern "C" for public definitions.
455 Bug fix: The show records facility (-s) only displayed information for
456 the first record in a file (and not for every record in the file).
458 Added option "-f <n>" to limit the logging of record operations. After
459 <n> records has been processed no logging is performed (unless errors
462 Bug fix: the compressed ISAM system didn't handle update operations
465 Added setting, "maxResultSetSize", to hold the number of records to
466 save in a result set.
468 Bug fix: Complete phrase did't work for search operations.
470 Bug fix: temporary result sets weren't deleted.
472 Reduced disk space for saved keys (storeKeys = 1).
474 Added optional, physical ANY (key replication)
476 Implemented proximity operator in search.
478 Bug fix: the path name buffers used by file match traversal routines
479 have been extended to support long file names.
481 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
482 configuration file. The resulting register without "storeKeys" is about
483 half the size, and the memory used by zebraidx during phase 2 (merge) is
484 reduced to a minimum.
486 Reworked the way Regexp-2 queries with error tolerance are handled and
487 specified. The documentation has been updated accordingly.
489 Bug fix: Zebrasrv didn't search correctly when queries contained masking
490 characters. This bug was introduced in 1.0a8.
492 Zebrasrv now tag records with the proper database name.
494 New settings, memMax and keyTmpDir.
496 Changed name of setting lockDir (previously called lockPath) and
497 setTmpDir (previously called tempSetPath).
499 Generalized and changed record type specifications. In short, there are:
501 grs.sgml structured, "SGML-like" syntax
502 grs.regx.<filter> structured, Regular expression filter
503 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
504 is the name of an abstract syntax file.
505 Bug fix: Result sets weren't sorted in operations involving boolean
506 operations with "ranked" operands.
510 Added national character-handling subsystem.
514 Small modifications to input filters and profiles.
516 Added support for SOIF syntax (with private OID).
520 Fixed buffer-size problem in indexing.
522 Added compression to temporary files for updating.
524 Added phrase registers.
526 Added dynamic mapping of search attribute to multiple termlists (ANY).
528 Scan support in multiple databases/registers.
530 Configuration settings are case-insensitive and single dash (-)
531 characters are ignored in comparisons.
533 The index processing ignores empty files - warning given.
535 New option to zebraidx (-V) displays version information.
539 Fixed problem in file-update system.
541 Fixed problem in shadow system; register was sometimes corrupted after
546 Fixed problems in the ISAM subsystem. Caused difficulties when updating
549 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
550 the rank and record number.
552 Fixed bug in the isam subsystem - caused a malfunction when accessing
553 words which occurred more than 10000 times.
555 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
558 Server can now run under inetd. Use option -i, and -w <directory> to
559 set working directory to desired location.
561 New zebraidx command: clean - removes temporary shadow files.
563 Fixed bug in ISAM system. Occurred rarely during register updates.
565 Logging during index merge phase is improved. The remaining running
568 Temporary files generated by zebraidx are removed after each run.
570 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
571 when doing scan operations in dictionaries with European characters.
575 A whole slew of updates, to make the first publicized release. Get the doc
580 Memory-problems in ISAM fixed. More blocktypes added to the default setup
581 to increase performance on larger databases.
583 Various minor changes in data management system.
587 A couple of portability-problems resolved.
589 Changed some malloc() to xmalloc().
