1 Added autoconf utility idzebra.m4 which defines --with-idzebra .
3 Added mechanism to ignore leading articles when doing full-field indexing,
4 based on the character map files. See the manual for further discussion.
6 Fixed bug in record management. Releasing blocks could result in
9 Fixed bug in isam:b. A tree split could result in a lost item.
11 Remove isamd. It's not been in use for a long time and isamb is better
14 Change SYSNO to be zint. Change pointers in isamc and isamb to zint.
15 Change block number in bfile/cfile to zint. zint is a long integer
16 (64-bit). This change practially removes register limits for Zebra.
18 Implement int-list encoding for ISAMs.
20 Added facility to make attibutes in grs.regx and grs.tcl filter using the
21 data command with argument -attribute <name> . The content of data is
22 the value of the attribute. This command should be used inside a
23 begin element , end element section.
25 Update zebra.nsi to NSIS 2.
27 Added a new 'cut' directive to charmaps (.chr files) which specifies that
28 only characters after the cutting char should be indexed.
30 Update Perl internals so that it matches the current Zebra API.
31 The recordGroup structure is no longer available. A group of resources
32 can still be referenced by setting groupName=>.. in various methods.
34 Maximum number of records to be sorted in a result set can be
35 specified by setting "sortmax". Default is 1000.
37 Allow use of string use attributes for regular attribute sets. The
38 name matches the name given in the attribute set file. All strings
39 starting with / are considered X-Path as usual.
41 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
42 element for XML tree. It may only pop off if -record is given.
44 Added grs.danbib filter - for Danish Bibliographic Centre.
46 Rename CHANGELOG to NEWS.
48 For text filter, return only header if elementSetName=H . elementSetName=R
49 returns contents only. Other elementSetName returns both header+content.
51 Added test for charmap and rusmarc.
53 Added feature charmaps (.chr) so that characters may be specified in
56 Fixed problem with encoding directive for charmap(.chr) files.
58 Allow Remote insert/delete/replace/update with record, recordIdNumber
59 (sysno) and/or recordIdOpaque(user supplied record Id). If both
60 IDs are omitted internal record ID match is assumed (recordId: - in
65 Fix bug. X-Path attribute expressions with spaces in them now works.
67 Fix base address for MARC output.
71 Fix bug with shadow and result set handling.
73 Implement MARCXML to ISO2709 conversion.
77 Add missing examples for Windows install.
79 Fix bug in regx filter to make it "greedy" again. This bug appeared
86 Fix XML error handling. Stop XML parse immediately if XML parse error
87 occur (i.e. produce one error only).
89 Zebra ignores "unsupported use attribute" for individual databases
90 when search multiple databases (unless all databases fail).
92 New filter grs.marcxml which works like grs.marc but produces MARCXML.
94 Added support for database deletion. It is possible to create/drop
95 a database from zebraidx utility. Note: only for isam:b.
97 Write zebrasrv.pid to lockdir.
99 Bug fix: result sets were not recovered correctly. Had to
100 add ODR handle for zebra_search_RPN in order to make it work.
102 Fixed a bug in regx filters that didn't do anchors (^) correctly.
104 Fixed a bug in searches with X-Path searches sometimes giving "extra"
107 Zebra server checks for zebrasrv.pid and refuses to start if it is already
108 locked by another (running) zebrasrv.
110 Fixed a bug with text being chunked in pieces for the grs.xml filter.
112 --- 1.3.11 2003/04/25
114 xelm code updates. xelm works regardless state of 'xpath enable/disable'
115 Avoid -L/usr/lib since that is already default library path.
117 Allow multiple updates within one transaction.
119 Fixed a bug with >2GB files (overflow in integer expression).
121 --- 1.3.10 2003/04/01
123 Fix linker error for Perl module.
125 Fix bug in and operation which in some cases could result in "extra"
126 hits. Bug was introduced in 1.3.5.
128 Fix bug in handling of schema conversion when producing numeric tags.
134 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
138 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
139 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
140 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
142 livrank: another experimental ranking algorithm. Source in livcode.c.
143 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
145 Contributed by Pete Mallinson, University of Liverpool.
147 Advanced MARC indexing. See doc/marc_indexing.xml
148 Oleg Kolobov <oleg at lib.tpu.ru>
150 Perl API updates and fixes.
151 Peter Popovics <pop at technomat.hu>
153 Fixed 'zebraidx delete'.
155 Implemented 'zebraidx clean'.
157 64-bit offsets for register files on WIN32 (no 2 GB limit).
159 Fixed a few memory leaks WRT sorting.
163 Fixed error handling : error code was not properly returned.
165 Support Truncation 104 (CCL).
169 Added missing source files for perl extension.
173 Implemented xelm directive.
175 Updated for newer version of YAZ (introduction of string schema).
177 Directory examples/zthes now part of distribution (was missing
178 in previous release).
180 New .abs directive, systag, that control where to put retrieval
181 information. The directive takes two arguments: system tag, element name.
182 System tag is one of : rank, sysno, size.
186 Perl Filter and Perl API. By Peter Popovics.
188 For zebra.cfg, if no profilePath is specified, directory
189 (prefix)/share/idzebra/tab
192 Zebra Examples in examples . Zebra tests in test.
194 Bug fix: sort index was not properly modified on
195 record updates/deletes.
197 Fix handling of character entities for sgml filter.
199 Move data1 to Zebra (used to be part of YAZ).
203 Fix character encoding of scan response terms.
205 Fix character decoding of scan request terms.
207 Fix ESpec handling (requires YAZ 1.9.1)
209 Fix searches for complete fields.
213 When name zebra is used in a filename or directory 'idzebra' is used
214 instead to avoid confusion with GNU zebra (routing software).
216 Zebra server stops with a fatal error if config file cannot be read.
218 New config setting, followLinks, that controls whether update of files
219 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
220 By default symbolic links are followed.
222 Fix MARC transfer . MARC fields had wrong data for multiple fields.
224 XML record reader moved from YAZ to Zebra, to make YAZ less
225 dependant on external libraries.
227 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
228 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
229 on systems that doesn't offer iconv.
231 XML record reader supports external system entities.
235 New .abs-directive "xpath" that takes one argument: "enable"
236 or "disable" to enable and disable XPath -indexing. If no "xpath"
237 direcive is found in .abs-file , XPath-indexing is disabled to ensure
238 backwards compatibility. For missing .abs-files XPath-indexing is
239 enabled so that such records are searchable.
241 Zebra warns about missing .abs-file only once (for each type).
243 Fixed a bug in file update where already-inserted files could
248 Zebra license changed to GNU GPL.
250 XPath-like queries used when RPN string attributes are used, eg.
251 @attr 1=/portal/title sometitle
252 @attr 1=/portal/title[@xml:lang=da] danishtitle
253 @attr 1=/portal/title/@xml:lang da
254 @attr 1=//title sometitle
256 Zebra uses UTF-8 internally:
257 1) New setting "encoding" for zebra.cfg that specifies encoding for
258 OCTET terms in queries and record encoding for most transfer syntaxes
259 (except those that use International Strings, such as GRS-1).
260 2) The encoding of International strings is UTF-8 by default. It
261 may be changed by character set negotiation. If character set
262 negotiation is in effect and if records are selected for conversion
263 these'll be converted to the selected character set - thus overriding
264 the encoding setting in zebra.cfg.
265 3) New directive "encoding" in .abs-files. This specifies the external
266 character encoding for files indexed by zebra. However, if records
267 themselves have an XML header that specifies and encoding that'll be used
270 XML filter (-t grs.xml).
272 Multiple registers. New setting in resource 'root' that holds base
273 directory for register(s). A group a databases may be put in separate
274 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
278 Fixes for Digital Unix
280 Implemented hits per term using USR:SearchResult-1.
282 New Zebra API. Locking system re-implemented.
284 --- 1.1.stable 2002/02/20
286 Rank weight can be controlled with attribute type 9. Default
287 value is 34. Recommended values between 1-36.
291 Updated for YAZ version 1.8.
293 Added support for termsets - a result set of terms matching
294 a given query. For @attr 8=<set> creates termset named <set>.
296 Added support for raw retrieval. Element Set Name R forces the
297 text filter which returns the record in its original form.
299 Added numerical sort - triggered by structure=numeric (4=109).
301 Remote record import using Z39.50 Extended Services and Segments.
303 Fixed bug where updating a database with user-defined attributes
304 could corrupt the register (bad storeKeys).
306 Multi-threaded version.
308 Fixed bug regarding proximity.
310 Documentation updates.
312 Fixed bug in record retrieval module that occured on 64-bit OSF
317 Fixed bug in makefile for WIN32.
319 Fixed bug in configure script - used bash-specific features.
323 Added support for multiple records in one file for filter grs.sgml.
325 Changed record index structure. New layout is incompatible with
326 previous releases. Added setting "recordcompression" to control
327 compression of records. Possible values are "none" (no
328 compression) and bzip2 (compression using libbz2).
330 Added XML transfer syntax support for retrieval of structured records.
331 Schema in CompSpec is recognised in retrieval of structured records.
333 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
334 that fails, the filter reads the file <filt>.flt (regx style filter).
336 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
337 Zebra's configure script automatically attempts to locate Tcl. For
338 manual Tcl configuration use option --with-tclconfig=<path> to specify
339 where Tcl's library files are located.
341 Implemented "compression" of Dictionary and ISAM system. Dictionary
344 Added "tagsysno" directive to zebra.cfg to control under which tag the
345 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
348 Added "tagrank" as above.
350 Changed file naming scheme for register files from <name>.mf.<no> to
353 Implemented "position"-flag for register type (as defined in
354 default.idx). When set to zero no position (or seqence number) is
355 saved in register for each word occurrence, thus saving some register
358 Implemented database mapping. Using mapdb one can specify a database
359 to be mapped to one or more physical databases. Usage:
360 mapdb <fromdb> <todb> ..
362 Added SOIF-filter. Thanks to Peter Valkenburg.
364 For the regx-filter "end element -record" may trigger a mark-of-record
365 if outer level is reached.
367 Tag sets may be typed in the reference to it. From the .abs-file the
368 "tagset" directive takes a third optional integer type for the tag set
369 referenced. From a .tag-file the "include" directive takes a third
370 optional type as well. The old "type" directive in the tag set itself
371 is still recognized but acts as the default type for the tag set.
373 Zebra supports the specification of arbitrary attributes sets, schemas
374 and tag sets, because of the change in YAZ' OID management system.
376 Fixed bug in Sort that caused it NOT to use character mapping as it
379 Zebra now uses GNU configure to generate Makefile(s).
381 Added un-optimised support for left and left/right truncation attributes.
383 Added support for relational operators on text when using RPN queries.
385 Added support for sort specifications in RPN queries. Type 7 specifies
386 'sort' where value 1=ascending, value 2=descending. The use attribute
387 specifies the field criteria as usual. The term specifies priority
388 where 0=first, 1=second, ...
390 Changed the way use attributes are specified in the recordId
393 Maximum number of databases in one Zebra register increased.
395 New setting, databasePath, which specifies that first directory during
396 update traversal is the database name (instead of a fixed one).
398 New setting, explainDatabase, which specifies that databases are
401 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
403 Implemented EXPLAIN database maintenance. Zebra automatically
404 generate - and update CategoryList, TargetInfo, DatabaseInfo,
405 AttributeSetInfo and AttributeDetails records at this stage. The
406 records may be transferred as GRS-1, SUTRS or Explain.
408 Fixed register spec so that colon isn't treated as size separator
409 unless followed by [0-9+-] in order to allow DOS drive specifications.
411 Fixed two bugs in ISAMC system.
413 Changed the way Zebra keeps its maintenance information about attribute
414 sets, available attributes, etc.. Records in "SGML" notation using an
415 EXPLAIN schema is now used when appropriate.
417 Bug fix: Index didn't handle update/insert/delete of the same record
418 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
419 first occurence of a record is considered.
421 Most searches now return correct number of hits.
423 New modular ranking system. Interested programmers are encouraged to
424 inspect rank1.c and improve the algorithm.
426 Bug fix: Lock files weren't removed as they should on NT.
428 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
429 specify a "sort register". Refer to the gils sample records which refer
430 to index type "s" which is specified as "sort" in the default.idx file.
431 Each sort criteria can either be Ascending or Descending and at most
432 three sort elements can be specified.
434 Bug fix: Character mapping didn't work for text files.
438 Simple ranked searches now return correct number of hits.
440 The test option (-s) only makes a read-lock on the index as well
441 as using read-only operations anywhere.
443 Moved towards generic character mapping. Configuration file default.idx
444 specifies character map files for register types w, p, u, etc.
446 Implemented "begin variant" for the sgml.regx - filter.
448 Fixed a few memory leaks.
450 Added support for C++, headers uses extern "C" for public definitions.
452 Bug fix: The show records facility (-s) only displayed information for
453 the first record in a file (and not for every record in the file).
455 Added option "-f <n>" to limit the logging of record operations. After
456 <n> records has been processed no logging is performed (unless errors
459 Bug fix: the compressed ISAM system didn't handle update operations
462 Added setting, "maxResultSetSize", to hold the number of records to
463 save in a result set.
465 Bug fix: Complete phrase did't work for search operations.
467 Bug fix: temporary result sets weren't deleted.
469 Reduced disk space for saved keys (storeKeys = 1).
471 Added optional, physical ANY (key replication)
473 Implemented proximity operator in search.
475 Bug fix: the path name buffers used by file match traversal routines
476 have been extended to support long file names.
478 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
479 configuration file. The resulting register without "storeKeys" is about
480 half the size, and the memory used by zebraidx during phase 2 (merge) is
481 reduced to a minimum.
483 Reworked the way Regexp-2 queries with error tolerance are handled and
484 specified. The documentation has been updated accordingly.
486 Bug fix: Zebrasrv didn't search correctly when queries contained masking
487 characters. This bug was introduced in 1.0a8.
489 Zebrasrv now tag records with the proper database name.
491 New settings, memMax and keyTmpDir.
493 Changed name of setting lockDir (previously called lockPath) and
494 setTmpDir (previously called tempSetPath).
496 Generalized and changed record type specifications. In short, there are:
498 grs.sgml structured, "SGML-like" syntax
499 grs.regx.<filter> structured, Regular expression filter
500 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
501 is the name of an abstract syntax file.
502 Bug fix: Result sets weren't sorted in operations involving boolean
503 operations with "ranked" operands.
507 Added national character-handling subsystem.
511 Small modifications to input filters and profiles.
513 Added support for SOIF syntax (with private OID).
517 Fixed buffer-size problem in indexing.
519 Added compression to temporary files for updating.
521 Added phrase registers.
523 Added dynamic mapping of search attribute to multiple termlists (ANY).
525 Scan support in multiple databases/registers.
527 Configuration settings are case-insensitive and single dash (-)
528 characters are ignored in comparisons.
530 The index processing ignores empty files - warning given.
532 New option to zebraidx (-V) displays version information.
536 Fixed problem in file-update system.
538 Fixed problem in shadow system; register was sometimes corrupted after
543 Fixed problems in the ISAM subsystem. Caused difficulties when updating
546 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
547 the rank and record number.
549 Fixed bug in the isam subsystem - caused a malfunction when accessing
550 words which occurred more than 10000 times.
552 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
555 Server can now run under inetd. Use option -i, and -w <directory> to
556 set working directory to desired location.
558 New zebraidx command: clean - removes temporary shadow files.
560 Fixed bug in ISAM system. Occurred rarely during register updates.
562 Logging during index merge phase is improved. The remaining running
565 Temporary files generated by zebraidx are removed after each run.
567 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
568 when doing scan operations in dictionaries with European characters.
572 A whole slew of updates, to make the first publicized release. Get the doc
577 Memory-problems in ISAM fixed. More blocktypes added to the default setup
578 to increase performance on larger databases.
580 Various minor changes in data management system.
584 A couple of portability-problems resolved.
586 Changed some malloc() to xmalloc().
