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