4 Add IDZebra.i to dist so that Perl extension builds again.
8 Added facility to make attibutes in grs.regx and grs.tcl filter using the
9 data command with argument -attribute <name> . The content of data is
10 the value of the attribute. This command should be used inside a
11 begin element , end element section.
13 Update zebra.nsi to NSIS 2.
15 Added a new 'cut' directive to charmaps (.chr files) which specifies that
16 only characters after the cutting char should be indexed.
18 Update Perl internals so that it matches the current Zebra API.
19 The recordGroup structure is no longer available. A group of resources
20 can still be referenced by setting groupName=>.. in various methods.
22 Maximum number of records to be sorted in a result set can be
23 specified by setting "sortmax". Default is 1000.
25 Allow use of string use attributes for regular attribute sets. The
26 name matches the name given in the attribute set file. All strings
27 starting with / are considered X-Path as usual.
29 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
30 element for XML tree. It may only pop off if -record is given.
32 Added grs.danbib filter - for Danish Bibliographic Centre.
34 Rename CHANGELOG to NEWS.
36 For text filter, return only header if elementSetName=H . elementSetName=R
37 returns contents only. Other elementSetName returns both header+content.
39 Added test for charmap and rusmarc.
41 Added feature charmaps (.chr) so that characters may be specified in
44 Fixed problem with encoding directive for charmap(.chr) files.
46 Allow Remote insert/delete/replace/update with record, recordIdNumber
47 (sysno) and/or recordIdOpaque(user supplied record Id). If both
48 IDs are omitted internal record ID match is assumed (recordId: - in
53 Fix bug. X-Path attribute expressions with spaces in them now works.
55 Fix base address for MARC output.
59 Fix bug with shadow and result set handling.
61 Implement MARCXML to ISO2709 conversion.
65 Add missing examples for Windows install.
67 Fix bug in regx filter to make it "greedy" again. This bug appeared
74 Fix XML error handling. Stop XML parse immediately if XML parse error
75 occur (i.e. produce one error only).
77 Zebra ignores "unsupported use attribute" for individual databases
78 when search multiple databases (unless all databases fail).
80 New filter grs.marcxml which works like grs.marc but produces MARCXML.
82 Added support for database deletion. It is possible to create/drop
83 a database from zebraidx utility. Note: only for isam:b.
85 Write zebrasrv.pid to lockdir.
87 Bug fix: result sets were not recovered correctly. Had to
88 add ODR handle for zebra_search_RPN in order to make it work.
90 Fixed a bug in regx filters that didn't do anchors (^) correctly.
92 Fixed a bug in searches with X-Path searches sometimes giving "extra"
95 Zebra server checks for zebrasrv.pid and refuses to start if it is already
96 locked by another (running) zebrasrv.
98 Fixed a bug with text being chunked in pieces for the grs.xml filter.
100 --- 1.3.11 2003/04/25
102 xelm code updates. xelm works regardless state of 'xpath enable/disable'
103 Avoid -L/usr/lib since that is already default library path.
105 Allow multiple updates within one transaction.
107 Fixed a bug with >2GB files (overflow in integer expression).
109 --- 1.3.10 2003/04/01
111 Fix linker error for Perl module.
113 Fix bug in and operation which in some cases could result in "extra"
114 hits. Bug was introduced in 1.3.5.
116 Fix bug in handling of schema conversion when producing numeric tags.
122 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
126 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
127 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
128 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
130 livrank: another experimental ranking algorithm. Source in livcode.c.
131 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
133 Contributed by Pete Mallinson, University of Liverpool.
135 Advanced MARC indexing. See doc/marc_indexing.xml
136 Oleg Kolobov <oleg at lib.tpu.ru>
138 Perl API updates and fixes.
139 Peter Popovics <pop at technomat.hu>
141 Fixed 'zebraidx delete'.
143 Implemented 'zebraidx clean'.
145 64-bit offsets for register files on WIN32 (no 2 GB limit).
147 Fixed a few memory leaks WRT sorting.
151 Fixed error handling : error code was not properly returned.
153 Support Truncation 104 (CCL).
157 Added missing source files for perl extension.
161 Implemented xelm directive.
163 Updated for newer version of YAZ (introduction of string schema).
165 Directory examples/zthes now part of distribution (was missing
166 in previous release).
168 New .abs directive, systag, that control where to put retrieval
169 information. The directive takes two arguments: system tag, element name.
170 System tag is one of : rank, sysno, size.
174 Perl Filter and Perl API. By Peter Popovics.
176 For zebra.cfg, if no profilePath is specified, directory
177 (prefix)/share/idzebra/tab
180 Zebra Examples in examples . Zebra tests in test.
182 Bug fix: sort index was not properly modified on
183 record updates/deletes.
185 Fix handling of character entities for sgml filter.
187 Move data1 to Zebra (used to be part of YAZ).
191 Fix character encoding of scan response terms.
193 Fix character decoding of scan request terms.
195 Fix ESpec handling (requires YAZ 1.9.1)
197 Fix searches for complete fields.
201 When name zebra is used in a filename or directory 'idzebra' is used
202 instead to avoid confusion with GNU zebra (routing software).
204 Zebra server stops with a fatal error if config file cannot be read.
206 New config setting, followLinks, that controls whether update of files
207 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
208 By default symbolic links are followed.
210 Fix MARC transfer . MARC fields had wrong data for multiple fields.
212 XML record reader moved from YAZ to Zebra, to make YAZ less
213 dependant on external libraries.
215 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
216 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
217 on systems that doesn't offer iconv.
219 XML record reader supports external system entities.
223 New .abs-directive "xpath" that takes one argument: "enable"
224 or "disable" to enable and disable XPath -indexing. If no "xpath"
225 direcive is found in .abs-file , XPath-indexing is disabled to ensure
226 backwards compatibility. For missing .abs-files XPath-indexing is
227 enabled so that such records are searchable.
229 Zebra warns about missing .abs-file only once (for each type).
231 Fixed a bug in file update where already-inserted files could
236 Zebra license changed to GNU GPL.
238 XPath-like queries used when RPN string attributes are used, eg.
239 @attr 1=/portal/title sometitle
240 @attr 1=/portal/title[@xml:lang=da] danishtitle
241 @attr 1=/portal/title/@xml:lang da
242 @attr 1=//title sometitle
244 Zebra uses UTF-8 internally:
245 1) New setting "encoding" for zebra.cfg that specifies encoding for
246 OCTET terms in queries and record encoding for most transfer syntaxes
247 (except those that use International Strings, such as GRS-1).
248 2) The encoding of International strings is UTF-8 by default. It
249 may be changed by character set negotiation. If character set
250 negotiation is in effect and if records are selected for conversion
251 these'll be converted to the selected character set - thus overriding
252 the encoding setting in zebra.cfg.
253 3) New directive "encoding" in .abs-files. This specifies the external
254 character encoding for files indexed by zebra. However, if records
255 themselves have an XML header that specifies and encoding that'll be used
258 XML filter (-t grs.xml).
260 Multiple registers. New setting in resource 'root' that holds base
261 directory for register(s). A group a databases may be put in separate
262 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
266 Fixes for Digital Unix
268 Implemented hits per term using USR:SearchResult-1.
270 New Zebra API. Locking system re-implemented.
272 --- 1.1.stable 2002/02/20
274 Rank weight can be controlled with attribute type 9. Default
275 value is 34. Recommended values between 1-36.
279 Updated for YAZ version 1.8.
281 Added support for termsets - a result set of terms matching
282 a given query. For @attr 8=<set> creates termset named <set>.
284 Added support for raw retrieval. Element Set Name R forces the
285 text filter which returns the record in its original form.
287 Added numerical sort - triggered by structure=numeric (4=109).
289 Remote record import using Z39.50 Extended Services and Segments.
291 Fixed bug where updating a database with user-defined attributes
292 could corrupt the register (bad storeKeys).
294 Multi-threaded version.
296 Fixed bug regarding proximity.
298 Documentation updates.
300 Fixed bug in record retrieval module that occured on 64-bit OSF
305 Fixed bug in makefile for WIN32.
307 Fixed bug in configure script - used bash-specific features.
311 Added support for multiple records in one file for filter grs.sgml.
313 Changed record index structure. New layout is incompatible with
314 previous releases. Added setting "recordcompression" to control
315 compression of records. Possible values are "none" (no
316 compression) and bzip2 (compression using libbz2).
318 Added XML transfer syntax support for retrieval of structured records.
319 Schema in CompSpec is recognised in retrieval of structured records.
321 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
322 that fails, the filter reads the file <filt>.flt (regx style filter).
324 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
325 Zebra's configure script automatically attempts to locate Tcl. For
326 manual Tcl configuration use option --with-tclconfig=<path> to specify
327 where Tcl's library files are located.
329 Implemented "compression" of Dictionary and ISAM system. Dictionary
332 Added "tagsysno" directive to zebra.cfg to control under which tag the
333 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
336 Added "tagrank" as above.
338 Changed file naming scheme for register files from <name>.mf.<no> to
341 Implemented "position"-flag for register type (as defined in
342 default.idx). When set to zero no position (or seqence number) is
343 saved in register for each word occurrence, thus saving some register
346 Implemented database mapping. Using mapdb one can specify a database
347 to be mapped to one or more physical databases. Usage:
348 mapdb <fromdb> <todb> ..
350 Added SOIF-filter. Thanks to Peter Valkenburg.
352 For the regx-filter "end element -record" may trigger a mark-of-record
353 if outer level is reached.
355 Tag sets may be typed in the reference to it. From the .abs-file the
356 "tagset" directive takes a third optional integer type for the tag set
357 referenced. From a .tag-file the "include" directive takes a third
358 optional type as well. The old "type" directive in the tag set itself
359 is still recognized but acts as the default type for the tag set.
361 Zebra supports the specification of arbitrary attributes sets, schemas
362 and tag sets, because of the change in YAZ' OID management system.
364 Fixed bug in Sort that caused it NOT to use character mapping as it
367 Zebra now uses GNU configure to generate Makefile(s).
369 Added un-optimised support for left and left/right truncation attributes.
371 Added support for relational operators on text when using RPN queries.
373 Added support for sort specifications in RPN queries. Type 7 specifies
374 'sort' where value 1=ascending, value 2=descending. The use attribute
375 specifies the field criteria as usual. The term specifies priority
376 where 0=first, 1=second, ...
378 Changed the way use attributes are specified in the recordId
381 Maximum number of databases in one Zebra register increased.
383 New setting, databasePath, which specifies that first directory during
384 update traversal is the database name (instead of a fixed one).
386 New setting, explainDatabase, which specifies that databases are
389 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
391 Implemented EXPLAIN database maintenance. Zebra automatically
392 generate - and update CategoryList, TargetInfo, DatabaseInfo,
393 AttributeSetInfo and AttributeDetails records at this stage. The
394 records may be transferred as GRS-1, SUTRS or Explain.
396 Fixed register spec so that colon isn't treated as size separator
397 unless followed by [0-9+-] in order to allow DOS drive specifications.
399 Fixed two bugs in ISAMC system.
401 Changed the way Zebra keeps its maintenance information about attribute
402 sets, available attributes, etc.. Records in "SGML" notation using an
403 EXPLAIN schema is now used when appropriate.
405 Bug fix: Index didn't handle update/insert/delete of the same record
406 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
407 first occurence of a record is considered.
409 Most searches now return correct number of hits.
411 New modular ranking system. Interested programmers are encouraged to
412 inspect rank1.c and improve the algorithm.
414 Bug fix: Lock files weren't removed as they should on NT.
416 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
417 specify a "sort register". Refer to the gils sample records which refer
418 to index type "s" which is specified as "sort" in the default.idx file.
419 Each sort criteria can either be Ascending or Descending and at most
420 three sort elements can be specified.
422 Bug fix: Character mapping didn't work for text files.
426 Simple ranked searches now return correct number of hits.
428 The test option (-s) only makes a read-lock on the index as well
429 as using read-only operations anywhere.
431 Moved towards generic character mapping. Configuration file default.idx
432 specifies character map files for register types w, p, u, etc.
434 Implemented "begin variant" for the sgml.regx - filter.
436 Fixed a few memory leaks.
438 Added support for C++, headers uses extern "C" for public definitions.
440 Bug fix: The show records facility (-s) only displayed information for
441 the first record in a file (and not for every record in the file).
443 Added option "-f <n>" to limit the logging of record operations. After
444 <n> records has been processed no logging is performed (unless errors
447 Bug fix: the compressed ISAM system didn't handle update operations
450 Added setting, "maxResultSetSize", to hold the number of records to
451 save in a result set.
453 Bug fix: Complete phrase did't work for search operations.
455 Bug fix: temporary result sets weren't deleted.
457 Reduced disk space for saved keys (storeKeys = 1).
459 Added optional, physical ANY (key replication)
461 Implemented proximity operator in search.
463 Bug fix: the path name buffers used by file match traversal routines
464 have been extended to support long file names.
466 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
467 configuration file. The resulting register without "storeKeys" is about
468 half the size, and the memory used by zebraidx during phase 2 (merge) is
469 reduced to a minimum.
471 Reworked the way Regexp-2 queries with error tolerance are handled and
472 specified. The documentation has been updated accordingly.
474 Bug fix: Zebrasrv didn't search correctly when queries contained masking
475 characters. This bug was introduced in 1.0a8.
477 Zebrasrv now tag records with the proper database name.
479 New settings, memMax and keyTmpDir.
481 Changed name of setting lockDir (previously called lockPath) and
482 setTmpDir (previously called tempSetPath).
484 Generalized and changed record type specifications. In short, there are:
486 grs.sgml structured, "SGML-like" syntax
487 grs.regx.<filter> structured, Regular expression filter
488 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
489 is the name of an abstract syntax file.
490 Bug fix: Result sets weren't sorted in operations involving boolean
491 operations with "ranked" operands.
495 Added national character-handling subsystem.
499 Small modifications to input filters and profiles.
501 Added support for SOIF syntax (with private OID).
505 Fixed buffer-size problem in indexing.
507 Added compression to temporary files for updating.
509 Added phrase registers.
511 Added dynamic mapping of search attribute to multiple termlists (ANY).
513 Scan support in multiple databases/registers.
515 Configuration settings are case-insensitive and single dash (-)
516 characters are ignored in comparisons.
518 The index processing ignores empty files - warning given.
520 New option to zebraidx (-V) displays version information.
524 Fixed problem in file-update system.
526 Fixed problem in shadow system; register was sometimes corrupted after
531 Fixed problems in the ISAM subsystem. Caused difficulties when updating
534 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
535 the rank and record number.
537 Fixed bug in the isam subsystem - caused a malfunction when accessing
538 words which occurred more than 10000 times.
540 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
543 Server can now run under inetd. Use option -i, and -w <directory> to
544 set working directory to desired location.
546 New zebraidx command: clean - removes temporary shadow files.
548 Fixed bug in ISAM system. Occurred rarely during register updates.
550 Logging during index merge phase is improved. The remaining running
553 Temporary files generated by zebraidx are removed after each run.
555 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
556 when doing scan operations in dictionaries with European characters.
560 A whole slew of updates, to make the first publicized release. Get the doc
565 Memory-problems in ISAM fixed. More blocktypes added to the default setup
566 to increase performance on larger databases.
568 Various minor changes in data management system.
572 A couple of portability-problems resolved.
574 Changed some malloc() to xmalloc().
