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