2 Added grs.danbib filter - for Danish Bibliographic Centre.
4 Rename CHANGELOG to NEWS.
8 For text filter, return only header if elementSetName=H . elementSetName=R
9 returns contents only. Other elementSetName returns both header+content.
11 Added test for charmap and rusmarc.
13 Added feature charmaps (.chr) so that characters may be specified in
16 Fixed problem with encoding directive for charmap(.chr) files.
18 Allow Remote insert/delete/replace/update with record, recordIdNumber
19 (sysno) and/or recordIdOpaque(user supplied record Id). If both
20 IDs are omitted internal record ID match is assumed (recordId: - in
25 Fix bug. X-Path attribute expressions with spaces in them now works.
27 Fix base address for MARC output.
31 Fix bug with shadow and result set handling.
33 Implement MARCXML to ISO2709 conversion.
37 Add missing examples for Windows install.
39 Fix bug in regx filter to make it "greedy" again. This bug appeared
46 Fix XML error handling. Stop XML parse immediately if XML parse error
47 occur (i.e. produce one error only).
49 Zebra ignores "unsupported use attribute" for individual databases
50 when search multiple databases (unless all databases fail).
52 New filter grs.marcxml which works like grs.marc but produces MARCXML.
54 Added support for database deletion. It is possible to create/drop
55 a database from zebraidx utility. Note: only for isam:b.
57 Write zebrasrv.pid to lockdir.
59 Bug fix: result sets were not recovered correctly. Had to
60 add ODR handle for zebra_search_RPN in order to make it work.
62 Fixed a bug in regx filters that didn't do anchors (^) correctly.
64 Fixed a bug in searches with X-Path searches sometimes giving "extra"
67 Zebra server checks for zebrasrv.pid and refuses to start if it is already
68 locked by another (running) zebrasrv.
70 Fixed a bug with text being chunked in pieces for the grs.xml filter.
74 xelm code updates. xelm works regardless state of 'xpath enable/disable'
75 Avoid -L/usr/lib since that is already default library path.
77 Allow multiple updates within one transaction.
79 Fixed a bug with >2GB files (overflow in integer expression).
83 Fix linker error for Perl module.
85 Fix bug in and operation which in some cases could result in "extra"
86 hits. Bug was introduced in 1.3.5.
88 Fix bug in handling of schema conversion when producing numeric tags.
94 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
98 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
99 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
100 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
102 livrank: another experimental ranking algorithm. Source in livcode.c.
103 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
105 Contributed by Pete Mallinson, University of Liverpool.
107 Advanced MARC indexing. See doc/marc_indexing.xml
108 Oleg Kolobov <oleg at lib.tpu.ru>
110 Perl API updates and fixes.
111 Peter Popovics <pop at technomat.hu>
113 Fixed 'zebraidx delete'.
115 Implemented 'zebraidx clean'.
117 64-bit offsets for register files on WIN32 (no 2 GB limit).
119 Fixed a few memory leaks WRT sorting.
123 Fixed error handling : error code was not properly returned.
125 Support Truncation 104 (CCL).
129 Added missing source files for perl extension.
133 Implemented xelm directive.
135 Updated for newer version of YAZ (introduction of string schema).
137 Directory examples/zthes now part of distribution (was missing
138 in previous release).
140 New .abs directive, systag, that control where to put retrieval
141 information. The directive takes two arguments: system tag, element name.
142 System tag is one of : rank, sysno, size.
146 Perl Filter and Perl API. By Peter Popovics.
148 For zebra.cfg, if no profilePath is specified, directory
149 (prefix)/share/idzebra/tab
152 Zebra Examples in examples . Zebra tests in test.
154 Bug fix: sort index was not properly modified on
155 record updates/deletes.
157 Fix handling of character entities for sgml filter.
159 Move data1 to Zebra (used to be part of YAZ).
163 Fix character encoding of scan response terms.
165 Fix character decoding of scan request terms.
167 Fix ESpec handling (requires YAZ 1.9.1)
169 Fix searches for complete fields.
173 When name zebra is used in a filename or directory 'idzebra' is used
174 instead to avoid confusion with GNU zebra (routing software).
176 Zebra server stops with a fatal error if config file cannot be read.
178 New config setting, followLinks, that controls whether update of files
179 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
180 By default symbolic links are followed.
182 Fix MARC transfer . MARC fields had wrong data for multiple fields.
184 XML record reader moved from YAZ to Zebra, to make YAZ less
185 dependant on external libraries.
187 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
188 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
189 on systems that doesn't offer iconv.
191 XML record reader supports external system entities.
195 New .abs-directive "xpath" that takes one argument: "enable"
196 or "disable" to enable and disable XPath -indexing. If no "xpath"
197 direcive is found in .abs-file , XPath-indexing is disabled to ensure
198 backwards compatibility. For missing .abs-files XPath-indexing is
199 enabled so that such records are searchable.
201 Zebra warns about missing .abs-file only once (for each type).
203 Fixed a bug in file update where already-inserted files could
208 Zebra license changed to GNU GPL.
210 XPath-like queries used when RPN string attributes are used, eg.
211 @attr 1=/portal/title sometitle
212 @attr 1=/portal/title[@xml:lang=da] danishtitle
213 @attr 1=/portal/title/@xml:lang da
214 @attr 1=//title sometitle
216 Zebra uses UTF-8 internally:
217 1) New setting "encoding" for zebra.cfg that specifies encoding for
218 OCTET terms in queries and record encoding for most transfer syntaxes
219 (except those that use International Strings, such as GRS-1).
220 2) The encoding of International strings is UTF-8 by default. It
221 may be changed by character set negotiation. If character set
222 negotiation is in effect and if records are selected for conversion
223 these'll be converted to the selected character set - thus overriding
224 the encoding setting in zebra.cfg.
225 3) New directive "encoding" in .abs-files. This specifies the external
226 character encoding for files indexed by zebra. However, if records
227 themselves have an XML header that specifies and encoding that'll be used
230 XML filter (-t grs.xml).
232 Multiple registers. New setting in resource 'root' that holds base
233 directory for register(s). A group a databases may be put in separate
234 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
238 Fixes for Digital Unix
240 Implemented hits per term using USR:SearchResult-1.
242 New Zebra API. Locking system re-implemented.
244 --- 1.1.stable 2002/02/20
246 Rank weight can be controlled with attribute type 9. Default
247 value is 34. Recommended values between 1-36.
251 Updated for YAZ version 1.8.
253 Added support for termsets - a result set of terms matching
254 a given query. For @attr 8=<set> creates termset named <set>.
256 Added support for raw retrieval. Element Set Name R forces the
257 text filter which returns the record in its original form.
259 Added numerical sort - triggered by structure=numeric (4=109).
261 Remote record import using Z39.50 Extended Services and Segments.
263 Fixed bug where updating a database with user-defined attributes
264 could corrupt the register (bad storeKeys).
266 Multi-threaded version.
268 Fixed bug regarding proximity.
270 Documentation updates.
272 Fixed bug in record retrieval module that occured on 64-bit OSF
277 Fixed bug in makefile for WIN32.
279 Fixed bug in configure script - used bash-specific features.
283 Added support for multiple records in one file for filter grs.sgml.
285 Changed record index structure. New layout is incompatible with
286 previous releases. Added setting "recordcompression" to control
287 compression of records. Possible values are "none" (no
288 compression) and bzip2 (compression using libbz2).
290 Added XML transfer syntax support for retrieval of structured records.
291 Schema in CompSpec is recognised in retrieval of structured records.
293 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
294 that fails, the filter reads the file <filt>.flt (regx style filter).
296 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
297 Zebra's configure script automatically attempts to locate Tcl. For
298 manual Tcl configuration use option --with-tclconfig=<path> to specify
299 where Tcl's library files are located.
301 Implemented "compression" of Dictionary and ISAM system. Dictionary
304 Added "tagsysno" directive to zebra.cfg to control under which tag the
305 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
308 Added "tagrank" as above.
310 Changed file naming scheme for register files from <name>.mf.<no> to
313 Implemented "position"-flag for register type (as defined in
314 default.idx). When set to zero no position (or seqence number) is
315 saved in register for each word occurrence, thus saving some register
318 Implemented database mapping. Using mapdb one can specify a database
319 to be mapped to one or more physical databases. Usage:
320 mapdb <fromdb> <todb> ..
322 Added SOIF-filter. Thanks to Peter Valkenburg.
324 For the regx-filter "end element -record" may trigger a mark-of-record
325 if outer level is reached.
327 Tag sets may be typed in the reference to it. From the .abs-file the
328 "tagset" directive takes a third optional integer type for the tag set
329 referenced. From a .tag-file the "include" directive takes a third
330 optional type as well. The old "type" directive in the tag set itself
331 is still recognized but acts as the default type for the tag set.
333 Zebra supports the specification of arbitrary attributes sets, schemas
334 and tag sets, because of the change in YAZ' OID management system.
336 Fixed bug in Sort that caused it NOT to use character mapping as it
339 Zebra now uses GNU configure to generate Makefile(s).
341 Added un-optimised support for left and left/right truncation attributes.
343 Added support for relational operators on text when using RPN queries.
345 Added support for sort specifications in RPN queries. Type 7 specifies
346 'sort' where value 1=ascending, value 2=descending. The use attribute
347 specifies the field criteria as usual. The term specifies priority
348 where 0=first, 1=second, ...
350 Changed the way use attributes are specified in the recordId
353 Maximum number of databases in one Zebra register increased.
355 New setting, databasePath, which specifies that first directory during
356 update traversal is the database name (instead of a fixed one).
358 New setting, explainDatabase, which specifies that databases are
361 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
363 Implemented EXPLAIN database maintenance. Zebra automatically
364 generate - and update CategoryList, TargetInfo, DatabaseInfo,
365 AttributeSetInfo and AttributeDetails records at this stage. The
366 records may be transferred as GRS-1, SUTRS or Explain.
368 Fixed register spec so that colon isn't treated as size separator
369 unless followed by [0-9+-] in order to allow DOS drive specifications.
371 Fixed two bugs in ISAMC system.
373 Changed the way Zebra keeps its maintenance information about attribute
374 sets, available attributes, etc.. Records in "SGML" notation using an
375 EXPLAIN schema is now used when appropriate.
377 Bug fix: Index didn't handle update/insert/delete of the same record
378 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
379 first occurence of a record is considered.
381 Most searches now return correct number of hits.
383 New modular ranking system. Interested programmers are encouraged to
384 inspect rank1.c and improve the algorithm.
386 Bug fix: Lock files weren't removed as they should on NT.
388 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
389 specify a "sort register". Refer to the gils sample records which refer
390 to index type "s" which is specified as "sort" in the default.idx file.
391 Each sort criteria can either be Ascending or Descending and at most
392 three sort elements can be specified.
394 Bug fix: Character mapping didn't work for text files.
398 Simple ranked searches now return correct number of hits.
400 The test option (-s) only makes a read-lock on the index as well
401 as using read-only operations anywhere.
403 Moved towards generic character mapping. Configuration file default.idx
404 specifies character map files for register types w, p, u, etc.
406 Implemented "begin variant" for the sgml.regx - filter.
408 Fixed a few memory leaks.
410 Added support for C++, headers uses extern "C" for public definitions.
412 Bug fix: The show records facility (-s) only displayed information for
413 the first record in a file (and not for every record in the file).
415 Added option "-f <n>" to limit the logging of record operations. After
416 <n> records has been processed no logging is performed (unless errors
419 Bug fix: the compressed ISAM system didn't handle update operations
422 Added setting, "maxResultSetSize", to hold the number of records to
423 save in a result set.
425 Bug fix: Complete phrase did't work for search operations.
427 Bug fix: temporary result sets weren't deleted.
429 Reduced disk space for saved keys (storeKeys = 1).
431 Added optional, physical ANY (key replication)
433 Implemented proximity operator in search.
435 Bug fix: the path name buffers used by file match traversal routines
436 have been extended to support long file names.
438 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
439 configuration file. The resulting register without "storeKeys" is about
440 half the size, and the memory used by zebraidx during phase 2 (merge) is
441 reduced to a minimum.
443 Reworked the way Regexp-2 queries with error tolerance are handled and
444 specified. The documentation has been updated accordingly.
446 Bug fix: Zebrasrv didn't search correctly when queries contained masking
447 characters. This bug was introduced in 1.0a8.
449 Zebrasrv now tag records with the proper database name.
451 New settings, memMax and keyTmpDir.
453 Changed name of setting lockDir (previously called lockPath) and
454 setTmpDir (previously called tempSetPath).
456 Generalized and changed record type specifications. In short, there are:
458 grs.sgml structured, "SGML-like" syntax
459 grs.regx.<filter> structured, Regular expression filter
460 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
461 is the name of an abstract syntax file.
462 Bug fix: Result sets weren't sorted in operations involving boolean
463 operations with "ranked" operands.
467 Added national character-handling subsystem.
471 Small modifications to input filters and profiles.
473 Added support for SOIF syntax (with private OID).
477 Fixed buffer-size problem in indexing.
479 Added compression to temporary files for updating.
481 Added phrase registers.
483 Added dynamic mapping of search attribute to multiple termlists (ANY).
485 Scan support in multiple databases/registers.
487 Configuration settings are case-insensitive and single dash (-)
488 characters are ignored in comparisons.
490 The index processing ignores empty files - warning given.
492 New option to zebraidx (-V) displays version information.
496 Fixed problem in file-update system.
498 Fixed problem in shadow system; register was sometimes corrupted after
503 Fixed problems in the ISAM subsystem. Caused difficulties when updating
506 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
507 the rank and record number.
509 Fixed bug in the isam subsystem - caused a malfunction when accessing
510 words which occurred more than 10000 times.
512 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
515 Server can now run under inetd. Use option -i, and -w <directory> to
516 set working directory to desired location.
518 New zebraidx command: clean - removes temporary shadow files.
520 Fixed bug in ISAM system. Occurred rarely during register updates.
522 Logging during index merge phase is improved. The remaining running
525 Temporary files generated by zebraidx are removed after each run.
527 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
528 when doing scan operations in dictionaries with European characters.
532 A whole slew of updates, to make the first publicized release. Get the doc
537 Memory-problems in ISAM fixed. More blocktypes added to the default setup
538 to increase performance on larger databases.
540 Various minor changes in data management system.
544 A couple of portability-problems resolved.
546 Changed some malloc() to xmalloc().
