4 Avoid crash in ISAMB when isamb_pp_open gets ISAMB_POS = 0. In
5 this case EOF (no entries) is signalled. It fixes problem with
6 terms being deleted. See bug #109.
8 Fixed bug #169: Phrase term counts does not work. The bug exists in
11 Added mechanism to ignore leading articles when doing full-field indexing,
12 based on the character map files. See the manual for further discussion.
16 Fixed bug in record management. Releasing blocks could result in
19 Fixed bug in isam:b. A tree split could result in a lost item.
23 Add IDZebra.i to dist so that Perl extension builds again.
27 Added facility to make attibutes in grs.regx and grs.tcl filter using the
28 data command with argument -attribute <name> . The content of data is
29 the value of the attribute. This command should be used inside a
30 begin element , end element section.
32 Update zebra.nsi to NSIS 2.
34 Added a new 'cut' directive to charmaps (.chr files) which specifies that
35 only characters after the cutting char should be indexed.
37 Update Perl internals so that it matches the current Zebra API.
38 The recordGroup structure is no longer available. A group of resources
39 can still be referenced by setting groupName=>.. in various methods.
41 Maximum number of records to be sorted in a result set can be
42 specified by setting "sortmax". Default is 1000.
44 Allow use of string use attributes for regular attribute sets. The
45 name matches the name given in the attribute set file. All strings
46 starting with / are considered X-Path as usual.
48 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
49 element for XML tree. It may only pop off if -record is given.
51 Added grs.danbib filter - for Danish Bibliographic Centre.
53 Rename CHANGELOG to NEWS.
55 For text filter, return only header if elementSetName=H . elementSetName=R
56 returns contents only. Other elementSetName returns both header+content.
58 Added test for charmap and rusmarc.
60 Added feature charmaps (.chr) so that characters may be specified in
63 Fixed problem with encoding directive for charmap(.chr) files.
65 Allow Remote insert/delete/replace/update with record, recordIdNumber
66 (sysno) and/or recordIdOpaque(user supplied record Id). If both
67 IDs are omitted internal record ID match is assumed (recordId: - in
72 Fix bug. X-Path attribute expressions with spaces in them now works.
74 Fix base address for MARC output.
78 Fix bug with shadow and result set handling.
80 Implement MARCXML to ISO2709 conversion.
84 Add missing examples for Windows install.
86 Fix bug in regx filter to make it "greedy" again. This bug appeared
93 Fix XML error handling. Stop XML parse immediately if XML parse error
94 occur (i.e. produce one error only).
96 Zebra ignores "unsupported use attribute" for individual databases
97 when search multiple databases (unless all databases fail).
99 New filter grs.marcxml which works like grs.marc but produces MARCXML.
101 Added support for database deletion. It is possible to create/drop
102 a database from zebraidx utility. Note: only for isam:b.
104 Write zebrasrv.pid to lockdir.
106 Bug fix: result sets were not recovered correctly. Had to
107 add ODR handle for zebra_search_RPN in order to make it work.
109 Fixed a bug in regx filters that didn't do anchors (^) correctly.
111 Fixed a bug in searches with X-Path searches sometimes giving "extra"
114 Zebra server checks for zebrasrv.pid and refuses to start if it is already
115 locked by another (running) zebrasrv.
117 Fixed a bug with text being chunked in pieces for the grs.xml filter.
119 --- 1.3.11 2003/04/25
121 xelm code updates. xelm works regardless state of 'xpath enable/disable'
122 Avoid -L/usr/lib since that is already default library path.
124 Allow multiple updates within one transaction.
126 Fixed a bug with >2GB files (overflow in integer expression).
128 --- 1.3.10 2003/04/01
130 Fix linker error for Perl module.
132 Fix bug in and operation which in some cases could result in "extra"
133 hits. Bug was introduced in 1.3.5.
135 Fix bug in handling of schema conversion when producing numeric tags.
141 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
145 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
146 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
147 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
149 livrank: another experimental ranking algorithm. Source in livcode.c.
150 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
152 Contributed by Pete Mallinson, University of Liverpool.
154 Advanced MARC indexing. See doc/marc_indexing.xml
155 Oleg Kolobov <oleg at lib.tpu.ru>
157 Perl API updates and fixes.
158 Peter Popovics <pop at technomat.hu>
160 Fixed 'zebraidx delete'.
162 Implemented 'zebraidx clean'.
164 64-bit offsets for register files on WIN32 (no 2 GB limit).
166 Fixed a few memory leaks WRT sorting.
170 Fixed error handling : error code was not properly returned.
172 Support Truncation 104 (CCL).
176 Added missing source files for perl extension.
180 Implemented xelm directive.
182 Updated for newer version of YAZ (introduction of string schema).
184 Directory examples/zthes now part of distribution (was missing
185 in previous release).
187 New .abs directive, systag, that control where to put retrieval
188 information. The directive takes two arguments: system tag, element name.
189 System tag is one of : rank, sysno, size.
193 Perl Filter and Perl API. By Peter Popovics.
195 For zebra.cfg, if no profilePath is specified, directory
196 (prefix)/share/idzebra/tab
199 Zebra Examples in examples . Zebra tests in test.
201 Bug fix: sort index was not properly modified on
202 record updates/deletes.
204 Fix handling of character entities for sgml filter.
206 Move data1 to Zebra (used to be part of YAZ).
210 Fix character encoding of scan response terms.
212 Fix character decoding of scan request terms.
214 Fix ESpec handling (requires YAZ 1.9.1)
216 Fix searches for complete fields.
220 When name zebra is used in a filename or directory 'idzebra' is used
221 instead to avoid confusion with GNU zebra (routing software).
223 Zebra server stops with a fatal error if config file cannot be read.
225 New config setting, followLinks, that controls whether update of files
226 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
227 By default symbolic links are followed.
229 Fix MARC transfer . MARC fields had wrong data for multiple fields.
231 XML record reader moved from YAZ to Zebra, to make YAZ less
232 dependant on external libraries.
234 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
235 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
236 on systems that doesn't offer iconv.
238 XML record reader supports external system entities.
242 New .abs-directive "xpath" that takes one argument: "enable"
243 or "disable" to enable and disable XPath -indexing. If no "xpath"
244 direcive is found in .abs-file , XPath-indexing is disabled to ensure
245 backwards compatibility. For missing .abs-files XPath-indexing is
246 enabled so that such records are searchable.
248 Zebra warns about missing .abs-file only once (for each type).
250 Fixed a bug in file update where already-inserted files could
255 Zebra license changed to GNU GPL.
257 XPath-like queries used when RPN string attributes are used, eg.
258 @attr 1=/portal/title sometitle
259 @attr 1=/portal/title[@xml:lang=da] danishtitle
260 @attr 1=/portal/title/@xml:lang da
261 @attr 1=//title sometitle
263 Zebra uses UTF-8 internally:
264 1) New setting "encoding" for zebra.cfg that specifies encoding for
265 OCTET terms in queries and record encoding for most transfer syntaxes
266 (except those that use International Strings, such as GRS-1).
267 2) The encoding of International strings is UTF-8 by default. It
268 may be changed by character set negotiation. If character set
269 negotiation is in effect and if records are selected for conversion
270 these'll be converted to the selected character set - thus overriding
271 the encoding setting in zebra.cfg.
272 3) New directive "encoding" in .abs-files. This specifies the external
273 character encoding for files indexed by zebra. However, if records
274 themselves have an XML header that specifies and encoding that'll be used
277 XML filter (-t grs.xml).
279 Multiple registers. New setting in resource 'root' that holds base
280 directory for register(s). A group a databases may be put in separate
281 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
285 Fixes for Digital Unix
287 Implemented hits per term using USR:SearchResult-1.
289 New Zebra API. Locking system re-implemented.
291 --- 1.1.stable 2002/02/20
293 Rank weight can be controlled with attribute type 9. Default
294 value is 34. Recommended values between 1-36.
298 Updated for YAZ version 1.8.
300 Added support for termsets - a result set of terms matching
301 a given query. For @attr 8=<set> creates termset named <set>.
303 Added support for raw retrieval. Element Set Name R forces the
304 text filter which returns the record in its original form.
306 Added numerical sort - triggered by structure=numeric (4=109).
308 Remote record import using Z39.50 Extended Services and Segments.
310 Fixed bug where updating a database with user-defined attributes
311 could corrupt the register (bad storeKeys).
313 Multi-threaded version.
315 Fixed bug regarding proximity.
317 Documentation updates.
319 Fixed bug in record retrieval module that occured on 64-bit OSF
324 Fixed bug in makefile for WIN32.
326 Fixed bug in configure script - used bash-specific features.
330 Added support for multiple records in one file for filter grs.sgml.
332 Changed record index structure. New layout is incompatible with
333 previous releases. Added setting "recordcompression" to control
334 compression of records. Possible values are "none" (no
335 compression) and bzip2 (compression using libbz2).
337 Added XML transfer syntax support for retrieval of structured records.
338 Schema in CompSpec is recognised in retrieval of structured records.
340 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
341 that fails, the filter reads the file <filt>.flt (regx style filter).
343 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
344 Zebra's configure script automatically attempts to locate Tcl. For
345 manual Tcl configuration use option --with-tclconfig=<path> to specify
346 where Tcl's library files are located.
348 Implemented "compression" of Dictionary and ISAM system. Dictionary
351 Added "tagsysno" directive to zebra.cfg to control under which tag the
352 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
355 Added "tagrank" as above.
357 Changed file naming scheme for register files from <name>.mf.<no> to
360 Implemented "position"-flag for register type (as defined in
361 default.idx). When set to zero no position (or seqence number) is
362 saved in register for each word occurrence, thus saving some register
365 Implemented database mapping. Using mapdb one can specify a database
366 to be mapped to one or more physical databases. Usage:
367 mapdb <fromdb> <todb> ..
369 Added SOIF-filter. Thanks to Peter Valkenburg.
371 For the regx-filter "end element -record" may trigger a mark-of-record
372 if outer level is reached.
374 Tag sets may be typed in the reference to it. From the .abs-file the
375 "tagset" directive takes a third optional integer type for the tag set
376 referenced. From a .tag-file the "include" directive takes a third
377 optional type as well. The old "type" directive in the tag set itself
378 is still recognized but acts as the default type for the tag set.
380 Zebra supports the specification of arbitrary attributes sets, schemas
381 and tag sets, because of the change in YAZ' OID management system.
383 Fixed bug in Sort that caused it NOT to use character mapping as it
386 Zebra now uses GNU configure to generate Makefile(s).
388 Added un-optimised support for left and left/right truncation attributes.
390 Added support for relational operators on text when using RPN queries.
392 Added support for sort specifications in RPN queries. Type 7 specifies
393 'sort' where value 1=ascending, value 2=descending. The use attribute
394 specifies the field criteria as usual. The term specifies priority
395 where 0=first, 1=second, ...
397 Changed the way use attributes are specified in the recordId
400 Maximum number of databases in one Zebra register increased.
402 New setting, databasePath, which specifies that first directory during
403 update traversal is the database name (instead of a fixed one).
405 New setting, explainDatabase, which specifies that databases are
408 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
410 Implemented EXPLAIN database maintenance. Zebra automatically
411 generate - and update CategoryList, TargetInfo, DatabaseInfo,
412 AttributeSetInfo and AttributeDetails records at this stage. The
413 records may be transferred as GRS-1, SUTRS or Explain.
415 Fixed register spec so that colon isn't treated as size separator
416 unless followed by [0-9+-] in order to allow DOS drive specifications.
418 Fixed two bugs in ISAMC system.
420 Changed the way Zebra keeps its maintenance information about attribute
421 sets, available attributes, etc.. Records in "SGML" notation using an
422 EXPLAIN schema is now used when appropriate.
424 Bug fix: Index didn't handle update/insert/delete of the same record
425 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
426 first occurence of a record is considered.
428 Most searches now return correct number of hits.
430 New modular ranking system. Interested programmers are encouraged to
431 inspect rank1.c and improve the algorithm.
433 Bug fix: Lock files weren't removed as they should on NT.
435 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
436 specify a "sort register". Refer to the gils sample records which refer
437 to index type "s" which is specified as "sort" in the default.idx file.
438 Each sort criteria can either be Ascending or Descending and at most
439 three sort elements can be specified.
441 Bug fix: Character mapping didn't work for text files.
445 Simple ranked searches now return correct number of hits.
447 The test option (-s) only makes a read-lock on the index as well
448 as using read-only operations anywhere.
450 Moved towards generic character mapping. Configuration file default.idx
451 specifies character map files for register types w, p, u, etc.
453 Implemented "begin variant" for the sgml.regx - filter.
455 Fixed a few memory leaks.
457 Added support for C++, headers uses extern "C" for public definitions.
459 Bug fix: The show records facility (-s) only displayed information for
460 the first record in a file (and not for every record in the file).
462 Added option "-f <n>" to limit the logging of record operations. After
463 <n> records has been processed no logging is performed (unless errors
466 Bug fix: the compressed ISAM system didn't handle update operations
469 Added setting, "maxResultSetSize", to hold the number of records to
470 save in a result set.
472 Bug fix: Complete phrase did't work for search operations.
474 Bug fix: temporary result sets weren't deleted.
476 Reduced disk space for saved keys (storeKeys = 1).
478 Added optional, physical ANY (key replication)
480 Implemented proximity operator in search.
482 Bug fix: the path name buffers used by file match traversal routines
483 have been extended to support long file names.
485 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
486 configuration file. The resulting register without "storeKeys" is about
487 half the size, and the memory used by zebraidx during phase 2 (merge) is
488 reduced to a minimum.
490 Reworked the way Regexp-2 queries with error tolerance are handled and
491 specified. The documentation has been updated accordingly.
493 Bug fix: Zebrasrv didn't search correctly when queries contained masking
494 characters. This bug was introduced in 1.0a8.
496 Zebrasrv now tag records with the proper database name.
498 New settings, memMax and keyTmpDir.
500 Changed name of setting lockDir (previously called lockPath) and
501 setTmpDir (previously called tempSetPath).
503 Generalized and changed record type specifications. In short, there are:
505 grs.sgml structured, "SGML-like" syntax
506 grs.regx.<filter> structured, Regular expression filter
507 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
508 is the name of an abstract syntax file.
509 Bug fix: Result sets weren't sorted in operations involving boolean
510 operations with "ranked" operands.
514 Added national character-handling subsystem.
518 Small modifications to input filters and profiles.
520 Added support for SOIF syntax (with private OID).
524 Fixed buffer-size problem in indexing.
526 Added compression to temporary files for updating.
528 Added phrase registers.
530 Added dynamic mapping of search attribute to multiple termlists (ANY).
532 Scan support in multiple databases/registers.
534 Configuration settings are case-insensitive and single dash (-)
535 characters are ignored in comparisons.
537 The index processing ignores empty files - warning given.
539 New option to zebraidx (-V) displays version information.
543 Fixed problem in file-update system.
545 Fixed problem in shadow system; register was sometimes corrupted after
550 Fixed problems in the ISAM subsystem. Caused difficulties when updating
553 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
554 the rank and record number.
556 Fixed bug in the isam subsystem - caused a malfunction when accessing
557 words which occurred more than 10000 times.
559 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
562 Server can now run under inetd. Use option -i, and -w <directory> to
563 set working directory to desired location.
565 New zebraidx command: clean - removes temporary shadow files.
567 Fixed bug in ISAM system. Occurred rarely during register updates.
569 Logging during index merge phase is improved. The remaining running
572 Temporary files generated by zebraidx are removed after each run.
574 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
575 when doing scan operations in dictionaries with European characters.
579 A whole slew of updates, to make the first publicized release. Get the doc
584 Memory-problems in ISAM fixed. More blocktypes added to the default setup
585 to increase performance on larger databases.
587 Various minor changes in data management system.
591 A couple of portability-problems resolved.
593 Changed some malloc() to xmalloc().
