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