2 Allow use of string use attributes for regular attribute sets. The
3 name matches the name given in the attribute set file. All strings
4 starting with / are considered X-Path as usual.
6 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
7 element for XML tree. It may only pop off if -record is given.
9 Added grs.danbib filter - for Danish Bibliographic Centre.
11 Rename CHANGELOG to NEWS.
15 For text filter, return only header if elementSetName=H . elementSetName=R
16 returns contents only. Other elementSetName returns both header+content.
18 Added test for charmap and rusmarc.
20 Added feature charmaps (.chr) so that characters may be specified in
23 Fixed problem with encoding directive for charmap(.chr) files.
25 Allow Remote insert/delete/replace/update with record, recordIdNumber
26 (sysno) and/or recordIdOpaque(user supplied record Id). If both
27 IDs are omitted internal record ID match is assumed (recordId: - in
32 Fix bug. X-Path attribute expressions with spaces in them now works.
34 Fix base address for MARC output.
38 Fix bug with shadow and result set handling.
40 Implement MARCXML to ISO2709 conversion.
44 Add missing examples for Windows install.
46 Fix bug in regx filter to make it "greedy" again. This bug appeared
53 Fix XML error handling. Stop XML parse immediately if XML parse error
54 occur (i.e. produce one error only).
56 Zebra ignores "unsupported use attribute" for individual databases
57 when search multiple databases (unless all databases fail).
59 New filter grs.marcxml which works like grs.marc but produces MARCXML.
61 Added support for database deletion. It is possible to create/drop
62 a database from zebraidx utility. Note: only for isam:b.
64 Write zebrasrv.pid to lockdir.
66 Bug fix: result sets were not recovered correctly. Had to
67 add ODR handle for zebra_search_RPN in order to make it work.
69 Fixed a bug in regx filters that didn't do anchors (^) correctly.
71 Fixed a bug in searches with X-Path searches sometimes giving "extra"
74 Zebra server checks for zebrasrv.pid and refuses to start if it is already
75 locked by another (running) zebrasrv.
77 Fixed a bug with text being chunked in pieces for the grs.xml filter.
81 xelm code updates. xelm works regardless state of 'xpath enable/disable'
82 Avoid -L/usr/lib since that is already default library path.
84 Allow multiple updates within one transaction.
86 Fixed a bug with >2GB files (overflow in integer expression).
90 Fix linker error for Perl module.
92 Fix bug in and operation which in some cases could result in "extra"
93 hits. Bug was introduced in 1.3.5.
95 Fix bug in handling of schema conversion when producing numeric tags.
101 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
105 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
106 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
107 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
109 livrank: another experimental ranking algorithm. Source in livcode.c.
110 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
112 Contributed by Pete Mallinson, University of Liverpool.
114 Advanced MARC indexing. See doc/marc_indexing.xml
115 Oleg Kolobov <oleg at lib.tpu.ru>
117 Perl API updates and fixes.
118 Peter Popovics <pop at technomat.hu>
120 Fixed 'zebraidx delete'.
122 Implemented 'zebraidx clean'.
124 64-bit offsets for register files on WIN32 (no 2 GB limit).
126 Fixed a few memory leaks WRT sorting.
130 Fixed error handling : error code was not properly returned.
132 Support Truncation 104 (CCL).
136 Added missing source files for perl extension.
140 Implemented xelm directive.
142 Updated for newer version of YAZ (introduction of string schema).
144 Directory examples/zthes now part of distribution (was missing
145 in previous release).
147 New .abs directive, systag, that control where to put retrieval
148 information. The directive takes two arguments: system tag, element name.
149 System tag is one of : rank, sysno, size.
153 Perl Filter and Perl API. By Peter Popovics.
155 For zebra.cfg, if no profilePath is specified, directory
156 (prefix)/share/idzebra/tab
159 Zebra Examples in examples . Zebra tests in test.
161 Bug fix: sort index was not properly modified on
162 record updates/deletes.
164 Fix handling of character entities for sgml filter.
166 Move data1 to Zebra (used to be part of YAZ).
170 Fix character encoding of scan response terms.
172 Fix character decoding of scan request terms.
174 Fix ESpec handling (requires YAZ 1.9.1)
176 Fix searches for complete fields.
180 When name zebra is used in a filename or directory 'idzebra' is used
181 instead to avoid confusion with GNU zebra (routing software).
183 Zebra server stops with a fatal error if config file cannot be read.
185 New config setting, followLinks, that controls whether update of files
186 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
187 By default symbolic links are followed.
189 Fix MARC transfer . MARC fields had wrong data for multiple fields.
191 XML record reader moved from YAZ to Zebra, to make YAZ less
192 dependant on external libraries.
194 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
195 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
196 on systems that doesn't offer iconv.
198 XML record reader supports external system entities.
202 New .abs-directive "xpath" that takes one argument: "enable"
203 or "disable" to enable and disable XPath -indexing. If no "xpath"
204 direcive is found in .abs-file , XPath-indexing is disabled to ensure
205 backwards compatibility. For missing .abs-files XPath-indexing is
206 enabled so that such records are searchable.
208 Zebra warns about missing .abs-file only once (for each type).
210 Fixed a bug in file update where already-inserted files could
215 Zebra license changed to GNU GPL.
217 XPath-like queries used when RPN string attributes are used, eg.
218 @attr 1=/portal/title sometitle
219 @attr 1=/portal/title[@xml:lang=da] danishtitle
220 @attr 1=/portal/title/@xml:lang da
221 @attr 1=//title sometitle
223 Zebra uses UTF-8 internally:
224 1) New setting "encoding" for zebra.cfg that specifies encoding for
225 OCTET terms in queries and record encoding for most transfer syntaxes
226 (except those that use International Strings, such as GRS-1).
227 2) The encoding of International strings is UTF-8 by default. It
228 may be changed by character set negotiation. If character set
229 negotiation is in effect and if records are selected for conversion
230 these'll be converted to the selected character set - thus overriding
231 the encoding setting in zebra.cfg.
232 3) New directive "encoding" in .abs-files. This specifies the external
233 character encoding for files indexed by zebra. However, if records
234 themselves have an XML header that specifies and encoding that'll be used
237 XML filter (-t grs.xml).
239 Multiple registers. New setting in resource 'root' that holds base
240 directory for register(s). A group a databases may be put in separate
241 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
245 Fixes for Digital Unix
247 Implemented hits per term using USR:SearchResult-1.
249 New Zebra API. Locking system re-implemented.
251 --- 1.1.stable 2002/02/20
253 Rank weight can be controlled with attribute type 9. Default
254 value is 34. Recommended values between 1-36.
258 Updated for YAZ version 1.8.
260 Added support for termsets - a result set of terms matching
261 a given query. For @attr 8=<set> creates termset named <set>.
263 Added support for raw retrieval. Element Set Name R forces the
264 text filter which returns the record in its original form.
266 Added numerical sort - triggered by structure=numeric (4=109).
268 Remote record import using Z39.50 Extended Services and Segments.
270 Fixed bug where updating a database with user-defined attributes
271 could corrupt the register (bad storeKeys).
273 Multi-threaded version.
275 Fixed bug regarding proximity.
277 Documentation updates.
279 Fixed bug in record retrieval module that occured on 64-bit OSF
284 Fixed bug in makefile for WIN32.
286 Fixed bug in configure script - used bash-specific features.
290 Added support for multiple records in one file for filter grs.sgml.
292 Changed record index structure. New layout is incompatible with
293 previous releases. Added setting "recordcompression" to control
294 compression of records. Possible values are "none" (no
295 compression) and bzip2 (compression using libbz2).
297 Added XML transfer syntax support for retrieval of structured records.
298 Schema in CompSpec is recognised in retrieval of structured records.
300 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
301 that fails, the filter reads the file <filt>.flt (regx style filter).
303 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
304 Zebra's configure script automatically attempts to locate Tcl. For
305 manual Tcl configuration use option --with-tclconfig=<path> to specify
306 where Tcl's library files are located.
308 Implemented "compression" of Dictionary and ISAM system. Dictionary
311 Added "tagsysno" directive to zebra.cfg to control under which tag the
312 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
315 Added "tagrank" as above.
317 Changed file naming scheme for register files from <name>.mf.<no> to
320 Implemented "position"-flag for register type (as defined in
321 default.idx). When set to zero no position (or seqence number) is
322 saved in register for each word occurrence, thus saving some register
325 Implemented database mapping. Using mapdb one can specify a database
326 to be mapped to one or more physical databases. Usage:
327 mapdb <fromdb> <todb> ..
329 Added SOIF-filter. Thanks to Peter Valkenburg.
331 For the regx-filter "end element -record" may trigger a mark-of-record
332 if outer level is reached.
334 Tag sets may be typed in the reference to it. From the .abs-file the
335 "tagset" directive takes a third optional integer type for the tag set
336 referenced. From a .tag-file the "include" directive takes a third
337 optional type as well. The old "type" directive in the tag set itself
338 is still recognized but acts as the default type for the tag set.
340 Zebra supports the specification of arbitrary attributes sets, schemas
341 and tag sets, because of the change in YAZ' OID management system.
343 Fixed bug in Sort that caused it NOT to use character mapping as it
346 Zebra now uses GNU configure to generate Makefile(s).
348 Added un-optimised support for left and left/right truncation attributes.
350 Added support for relational operators on text when using RPN queries.
352 Added support for sort specifications in RPN queries. Type 7 specifies
353 'sort' where value 1=ascending, value 2=descending. The use attribute
354 specifies the field criteria as usual. The term specifies priority
355 where 0=first, 1=second, ...
357 Changed the way use attributes are specified in the recordId
360 Maximum number of databases in one Zebra register increased.
362 New setting, databasePath, which specifies that first directory during
363 update traversal is the database name (instead of a fixed one).
365 New setting, explainDatabase, which specifies that databases are
368 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
370 Implemented EXPLAIN database maintenance. Zebra automatically
371 generate - and update CategoryList, TargetInfo, DatabaseInfo,
372 AttributeSetInfo and AttributeDetails records at this stage. The
373 records may be transferred as GRS-1, SUTRS or Explain.
375 Fixed register spec so that colon isn't treated as size separator
376 unless followed by [0-9+-] in order to allow DOS drive specifications.
378 Fixed two bugs in ISAMC system.
380 Changed the way Zebra keeps its maintenance information about attribute
381 sets, available attributes, etc.. Records in "SGML" notation using an
382 EXPLAIN schema is now used when appropriate.
384 Bug fix: Index didn't handle update/insert/delete of the same record
385 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
386 first occurence of a record is considered.
388 Most searches now return correct number of hits.
390 New modular ranking system. Interested programmers are encouraged to
391 inspect rank1.c and improve the algorithm.
393 Bug fix: Lock files weren't removed as they should on NT.
395 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
396 specify a "sort register". Refer to the gils sample records which refer
397 to index type "s" which is specified as "sort" in the default.idx file.
398 Each sort criteria can either be Ascending or Descending and at most
399 three sort elements can be specified.
401 Bug fix: Character mapping didn't work for text files.
405 Simple ranked searches now return correct number of hits.
407 The test option (-s) only makes a read-lock on the index as well
408 as using read-only operations anywhere.
410 Moved towards generic character mapping. Configuration file default.idx
411 specifies character map files for register types w, p, u, etc.
413 Implemented "begin variant" for the sgml.regx - filter.
415 Fixed a few memory leaks.
417 Added support for C++, headers uses extern "C" for public definitions.
419 Bug fix: The show records facility (-s) only displayed information for
420 the first record in a file (and not for every record in the file).
422 Added option "-f <n>" to limit the logging of record operations. After
423 <n> records has been processed no logging is performed (unless errors
426 Bug fix: the compressed ISAM system didn't handle update operations
429 Added setting, "maxResultSetSize", to hold the number of records to
430 save in a result set.
432 Bug fix: Complete phrase did't work for search operations.
434 Bug fix: temporary result sets weren't deleted.
436 Reduced disk space for saved keys (storeKeys = 1).
438 Added optional, physical ANY (key replication)
440 Implemented proximity operator in search.
442 Bug fix: the path name buffers used by file match traversal routines
443 have been extended to support long file names.
445 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
446 configuration file. The resulting register without "storeKeys" is about
447 half the size, and the memory used by zebraidx during phase 2 (merge) is
448 reduced to a minimum.
450 Reworked the way Regexp-2 queries with error tolerance are handled and
451 specified. The documentation has been updated accordingly.
453 Bug fix: Zebrasrv didn't search correctly when queries contained masking
454 characters. This bug was introduced in 1.0a8.
456 Zebrasrv now tag records with the proper database name.
458 New settings, memMax and keyTmpDir.
460 Changed name of setting lockDir (previously called lockPath) and
461 setTmpDir (previously called tempSetPath).
463 Generalized and changed record type specifications. In short, there are:
465 grs.sgml structured, "SGML-like" syntax
466 grs.regx.<filter> structured, Regular expression filter
467 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
468 is the name of an abstract syntax file.
469 Bug fix: Result sets weren't sorted in operations involving boolean
470 operations with "ranked" operands.
474 Added national character-handling subsystem.
478 Small modifications to input filters and profiles.
480 Added support for SOIF syntax (with private OID).
484 Fixed buffer-size problem in indexing.
486 Added compression to temporary files for updating.
488 Added phrase registers.
490 Added dynamic mapping of search attribute to multiple termlists (ANY).
492 Scan support in multiple databases/registers.
494 Configuration settings are case-insensitive and single dash (-)
495 characters are ignored in comparisons.
497 The index processing ignores empty files - warning given.
499 New option to zebraidx (-V) displays version information.
503 Fixed problem in file-update system.
505 Fixed problem in shadow system; register was sometimes corrupted after
510 Fixed problems in the ISAM subsystem. Caused difficulties when updating
513 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
514 the rank and record number.
516 Fixed bug in the isam subsystem - caused a malfunction when accessing
517 words which occurred more than 10000 times.
519 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
522 Server can now run under inetd. Use option -i, and -w <directory> to
523 set working directory to desired location.
525 New zebraidx command: clean - removes temporary shadow files.
527 Fixed bug in ISAM system. Occurred rarely during register updates.
529 Logging during index merge phase is improved. The remaining running
532 Temporary files generated by zebraidx are removed after each run.
534 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
535 when doing scan operations in dictionaries with European characters.
539 A whole slew of updates, to make the first publicized release. Get the doc
544 Memory-problems in ISAM fixed. More blocktypes added to the default setup
545 to increase performance on larger databases.
547 Various minor changes in data management system.
551 A couple of portability-problems resolved.
553 Changed some malloc() to xmalloc().
