2 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
3 element for XML tree. It may only pop off if -record is given.
5 Added grs.danbib filter - for Danish Bibliographic Centre.
7 Rename CHANGELOG to NEWS.
11 For text filter, return only header if elementSetName=H . elementSetName=R
12 returns contents only. Other elementSetName returns both header+content.
14 Added test for charmap and rusmarc.
16 Added feature charmaps (.chr) so that characters may be specified in
19 Fixed problem with encoding directive for charmap(.chr) files.
21 Allow Remote insert/delete/replace/update with record, recordIdNumber
22 (sysno) and/or recordIdOpaque(user supplied record Id). If both
23 IDs are omitted internal record ID match is assumed (recordId: - in
28 Fix bug. X-Path attribute expressions with spaces in them now works.
30 Fix base address for MARC output.
34 Fix bug with shadow and result set handling.
36 Implement MARCXML to ISO2709 conversion.
40 Add missing examples for Windows install.
42 Fix bug in regx filter to make it "greedy" again. This bug appeared
49 Fix XML error handling. Stop XML parse immediately if XML parse error
50 occur (i.e. produce one error only).
52 Zebra ignores "unsupported use attribute" for individual databases
53 when search multiple databases (unless all databases fail).
55 New filter grs.marcxml which works like grs.marc but produces MARCXML.
57 Added support for database deletion. It is possible to create/drop
58 a database from zebraidx utility. Note: only for isam:b.
60 Write zebrasrv.pid to lockdir.
62 Bug fix: result sets were not recovered correctly. Had to
63 add ODR handle for zebra_search_RPN in order to make it work.
65 Fixed a bug in regx filters that didn't do anchors (^) correctly.
67 Fixed a bug in searches with X-Path searches sometimes giving "extra"
70 Zebra server checks for zebrasrv.pid and refuses to start if it is already
71 locked by another (running) zebrasrv.
73 Fixed a bug with text being chunked in pieces for the grs.xml filter.
77 xelm code updates. xelm works regardless state of 'xpath enable/disable'
78 Avoid -L/usr/lib since that is already default library path.
80 Allow multiple updates within one transaction.
82 Fixed a bug with >2GB files (overflow in integer expression).
86 Fix linker error for Perl module.
88 Fix bug in and operation which in some cases could result in "extra"
89 hits. Bug was introduced in 1.3.5.
91 Fix bug in handling of schema conversion when producing numeric tags.
97 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
101 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
102 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
103 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
105 livrank: another experimental ranking algorithm. Source in livcode.c.
106 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
108 Contributed by Pete Mallinson, University of Liverpool.
110 Advanced MARC indexing. See doc/marc_indexing.xml
111 Oleg Kolobov <oleg at lib.tpu.ru>
113 Perl API updates and fixes.
114 Peter Popovics <pop at technomat.hu>
116 Fixed 'zebraidx delete'.
118 Implemented 'zebraidx clean'.
120 64-bit offsets for register files on WIN32 (no 2 GB limit).
122 Fixed a few memory leaks WRT sorting.
126 Fixed error handling : error code was not properly returned.
128 Support Truncation 104 (CCL).
132 Added missing source files for perl extension.
136 Implemented xelm directive.
138 Updated for newer version of YAZ (introduction of string schema).
140 Directory examples/zthes now part of distribution (was missing
141 in previous release).
143 New .abs directive, systag, that control where to put retrieval
144 information. The directive takes two arguments: system tag, element name.
145 System tag is one of : rank, sysno, size.
149 Perl Filter and Perl API. By Peter Popovics.
151 For zebra.cfg, if no profilePath is specified, directory
152 (prefix)/share/idzebra/tab
155 Zebra Examples in examples . Zebra tests in test.
157 Bug fix: sort index was not properly modified on
158 record updates/deletes.
160 Fix handling of character entities for sgml filter.
162 Move data1 to Zebra (used to be part of YAZ).
166 Fix character encoding of scan response terms.
168 Fix character decoding of scan request terms.
170 Fix ESpec handling (requires YAZ 1.9.1)
172 Fix searches for complete fields.
176 When name zebra is used in a filename or directory 'idzebra' is used
177 instead to avoid confusion with GNU zebra (routing software).
179 Zebra server stops with a fatal error if config file cannot be read.
181 New config setting, followLinks, that controls whether update of files
182 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
183 By default symbolic links are followed.
185 Fix MARC transfer . MARC fields had wrong data for multiple fields.
187 XML record reader moved from YAZ to Zebra, to make YAZ less
188 dependant on external libraries.
190 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
191 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
192 on systems that doesn't offer iconv.
194 XML record reader supports external system entities.
198 New .abs-directive "xpath" that takes one argument: "enable"
199 or "disable" to enable and disable XPath -indexing. If no "xpath"
200 direcive is found in .abs-file , XPath-indexing is disabled to ensure
201 backwards compatibility. For missing .abs-files XPath-indexing is
202 enabled so that such records are searchable.
204 Zebra warns about missing .abs-file only once (for each type).
206 Fixed a bug in file update where already-inserted files could
211 Zebra license changed to GNU GPL.
213 XPath-like queries used when RPN string attributes are used, eg.
214 @attr 1=/portal/title sometitle
215 @attr 1=/portal/title[@xml:lang=da] danishtitle
216 @attr 1=/portal/title/@xml:lang da
217 @attr 1=//title sometitle
219 Zebra uses UTF-8 internally:
220 1) New setting "encoding" for zebra.cfg that specifies encoding for
221 OCTET terms in queries and record encoding for most transfer syntaxes
222 (except those that use International Strings, such as GRS-1).
223 2) The encoding of International strings is UTF-8 by default. It
224 may be changed by character set negotiation. If character set
225 negotiation is in effect and if records are selected for conversion
226 these'll be converted to the selected character set - thus overriding
227 the encoding setting in zebra.cfg.
228 3) New directive "encoding" in .abs-files. This specifies the external
229 character encoding for files indexed by zebra. However, if records
230 themselves have an XML header that specifies and encoding that'll be used
233 XML filter (-t grs.xml).
235 Multiple registers. New setting in resource 'root' that holds base
236 directory for register(s). A group a databases may be put in separate
237 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
241 Fixes for Digital Unix
243 Implemented hits per term using USR:SearchResult-1.
245 New Zebra API. Locking system re-implemented.
247 --- 1.1.stable 2002/02/20
249 Rank weight can be controlled with attribute type 9. Default
250 value is 34. Recommended values between 1-36.
254 Updated for YAZ version 1.8.
256 Added support for termsets - a result set of terms matching
257 a given query. For @attr 8=<set> creates termset named <set>.
259 Added support for raw retrieval. Element Set Name R forces the
260 text filter which returns the record in its original form.
262 Added numerical sort - triggered by structure=numeric (4=109).
264 Remote record import using Z39.50 Extended Services and Segments.
266 Fixed bug where updating a database with user-defined attributes
267 could corrupt the register (bad storeKeys).
269 Multi-threaded version.
271 Fixed bug regarding proximity.
273 Documentation updates.
275 Fixed bug in record retrieval module that occured on 64-bit OSF
280 Fixed bug in makefile for WIN32.
282 Fixed bug in configure script - used bash-specific features.
286 Added support for multiple records in one file for filter grs.sgml.
288 Changed record index structure. New layout is incompatible with
289 previous releases. Added setting "recordcompression" to control
290 compression of records. Possible values are "none" (no
291 compression) and bzip2 (compression using libbz2).
293 Added XML transfer syntax support for retrieval of structured records.
294 Schema in CompSpec is recognised in retrieval of structured records.
296 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
297 that fails, the filter reads the file <filt>.flt (regx style filter).
299 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
300 Zebra's configure script automatically attempts to locate Tcl. For
301 manual Tcl configuration use option --with-tclconfig=<path> to specify
302 where Tcl's library files are located.
304 Implemented "compression" of Dictionary and ISAM system. Dictionary
307 Added "tagsysno" directive to zebra.cfg to control under which tag the
308 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
311 Added "tagrank" as above.
313 Changed file naming scheme for register files from <name>.mf.<no> to
316 Implemented "position"-flag for register type (as defined in
317 default.idx). When set to zero no position (or seqence number) is
318 saved in register for each word occurrence, thus saving some register
321 Implemented database mapping. Using mapdb one can specify a database
322 to be mapped to one or more physical databases. Usage:
323 mapdb <fromdb> <todb> ..
325 Added SOIF-filter. Thanks to Peter Valkenburg.
327 For the regx-filter "end element -record" may trigger a mark-of-record
328 if outer level is reached.
330 Tag sets may be typed in the reference to it. From the .abs-file the
331 "tagset" directive takes a third optional integer type for the tag set
332 referenced. From a .tag-file the "include" directive takes a third
333 optional type as well. The old "type" directive in the tag set itself
334 is still recognized but acts as the default type for the tag set.
336 Zebra supports the specification of arbitrary attributes sets, schemas
337 and tag sets, because of the change in YAZ' OID management system.
339 Fixed bug in Sort that caused it NOT to use character mapping as it
342 Zebra now uses GNU configure to generate Makefile(s).
344 Added un-optimised support for left and left/right truncation attributes.
346 Added support for relational operators on text when using RPN queries.
348 Added support for sort specifications in RPN queries. Type 7 specifies
349 'sort' where value 1=ascending, value 2=descending. The use attribute
350 specifies the field criteria as usual. The term specifies priority
351 where 0=first, 1=second, ...
353 Changed the way use attributes are specified in the recordId
356 Maximum number of databases in one Zebra register increased.
358 New setting, databasePath, which specifies that first directory during
359 update traversal is the database name (instead of a fixed one).
361 New setting, explainDatabase, which specifies that databases are
364 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
366 Implemented EXPLAIN database maintenance. Zebra automatically
367 generate - and update CategoryList, TargetInfo, DatabaseInfo,
368 AttributeSetInfo and AttributeDetails records at this stage. The
369 records may be transferred as GRS-1, SUTRS or Explain.
371 Fixed register spec so that colon isn't treated as size separator
372 unless followed by [0-9+-] in order to allow DOS drive specifications.
374 Fixed two bugs in ISAMC system.
376 Changed the way Zebra keeps its maintenance information about attribute
377 sets, available attributes, etc.. Records in "SGML" notation using an
378 EXPLAIN schema is now used when appropriate.
380 Bug fix: Index didn't handle update/insert/delete of the same record
381 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
382 first occurence of a record is considered.
384 Most searches now return correct number of hits.
386 New modular ranking system. Interested programmers are encouraged to
387 inspect rank1.c and improve the algorithm.
389 Bug fix: Lock files weren't removed as they should on NT.
391 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
392 specify a "sort register". Refer to the gils sample records which refer
393 to index type "s" which is specified as "sort" in the default.idx file.
394 Each sort criteria can either be Ascending or Descending and at most
395 three sort elements can be specified.
397 Bug fix: Character mapping didn't work for text files.
401 Simple ranked searches now return correct number of hits.
403 The test option (-s) only makes a read-lock on the index as well
404 as using read-only operations anywhere.
406 Moved towards generic character mapping. Configuration file default.idx
407 specifies character map files for register types w, p, u, etc.
409 Implemented "begin variant" for the sgml.regx - filter.
411 Fixed a few memory leaks.
413 Added support for C++, headers uses extern "C" for public definitions.
415 Bug fix: The show records facility (-s) only displayed information for
416 the first record in a file (and not for every record in the file).
418 Added option "-f <n>" to limit the logging of record operations. After
419 <n> records has been processed no logging is performed (unless errors
422 Bug fix: the compressed ISAM system didn't handle update operations
425 Added setting, "maxResultSetSize", to hold the number of records to
426 save in a result set.
428 Bug fix: Complete phrase did't work for search operations.
430 Bug fix: temporary result sets weren't deleted.
432 Reduced disk space for saved keys (storeKeys = 1).
434 Added optional, physical ANY (key replication)
436 Implemented proximity operator in search.
438 Bug fix: the path name buffers used by file match traversal routines
439 have been extended to support long file names.
441 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
442 configuration file. The resulting register without "storeKeys" is about
443 half the size, and the memory used by zebraidx during phase 2 (merge) is
444 reduced to a minimum.
446 Reworked the way Regexp-2 queries with error tolerance are handled and
447 specified. The documentation has been updated accordingly.
449 Bug fix: Zebrasrv didn't search correctly when queries contained masking
450 characters. This bug was introduced in 1.0a8.
452 Zebrasrv now tag records with the proper database name.
454 New settings, memMax and keyTmpDir.
456 Changed name of setting lockDir (previously called lockPath) and
457 setTmpDir (previously called tempSetPath).
459 Generalized and changed record type specifications. In short, there are:
461 grs.sgml structured, "SGML-like" syntax
462 grs.regx.<filter> structured, Regular expression filter
463 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
464 is the name of an abstract syntax file.
465 Bug fix: Result sets weren't sorted in operations involving boolean
466 operations with "ranked" operands.
470 Added national character-handling subsystem.
474 Small modifications to input filters and profiles.
476 Added support for SOIF syntax (with private OID).
480 Fixed buffer-size problem in indexing.
482 Added compression to temporary files for updating.
484 Added phrase registers.
486 Added dynamic mapping of search attribute to multiple termlists (ANY).
488 Scan support in multiple databases/registers.
490 Configuration settings are case-insensitive and single dash (-)
491 characters are ignored in comparisons.
493 The index processing ignores empty files - warning given.
495 New option to zebraidx (-V) displays version information.
499 Fixed problem in file-update system.
501 Fixed problem in shadow system; register was sometimes corrupted after
506 Fixed problems in the ISAM subsystem. Caused difficulties when updating
509 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
510 the rank and record number.
512 Fixed bug in the isam subsystem - caused a malfunction when accessing
513 words which occurred more than 10000 times.
515 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
518 Server can now run under inetd. Use option -i, and -w <directory> to
519 set working directory to desired location.
521 New zebraidx command: clean - removes temporary shadow files.
523 Fixed bug in ISAM system. Occurred rarely during register updates.
525 Logging during index merge phase is improved. The remaining running
528 Temporary files generated by zebraidx are removed after each run.
530 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
531 when doing scan operations in dictionaries with European characters.
535 A whole slew of updates, to make the first publicized release. Get the doc
540 Memory-problems in ISAM fixed. More blocktypes added to the default setup
541 to increase performance on larger databases.
543 Various minor changes in data management system.
547 A couple of portability-problems resolved.
549 Changed some malloc() to xmalloc().
