1 Added 'melm' directive to absyn format to simplify config files
2 for MARC-style databases. See tab/marc21.abs for an example.
4 Added bath-compliant definition file marc21.abs for use with MARC databases.
6 Added autoconf utility idzebra.m4 which defines --with-idzebra .
8 Added mechanism to ignore leading articles when doing full-field indexing,
9 based on the character map files. See the manual for further discussion.
11 Fixed bug in record management. Releasing blocks could result in
14 Fixed bug in isam:b. A tree split could result in a lost item.
16 Remove isamd. It's not been in use for a long time and isamb is better
19 Change SYSNO to be zint. Change pointers in isamc and isamb to zint.
20 Change block number in bfile/cfile to zint. zint is a long integer
21 (64-bit). This change practially removes register limits for Zebra.
23 Implement int-list encoding for ISAMs.
25 Added facility to make attibutes in grs.regx and grs.tcl filter using the
26 data command with argument -attribute <name> . The content of data is
27 the value of the attribute. This command should be used inside a
28 begin element , end element section.
30 Update zebra.nsi to NSIS 2.
32 Added a new 'cut' directive to charmaps (.chr files) which specifies that
33 only characters after the cutting char should be indexed.
35 Update Perl internals so that it matches the current Zebra API.
36 The recordGroup structure is no longer available. A group of resources
37 can still be referenced by setting groupName=>.. in various methods.
39 Maximum number of records to be sorted in a result set can be
40 specified by setting "sortmax". Default is 1000.
42 Allow use of string use attributes for regular attribute sets. The
43 name matches the name given in the attribute set file. All strings
44 starting with / are considered X-Path as usual.
46 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
47 element for XML tree. It may only pop off if -record is given.
49 Added grs.danbib filter - for Danish Bibliographic Centre.
51 Rename CHANGELOG to NEWS.
53 For text filter, return only header if elementSetName=H . elementSetName=R
54 returns contents only. Other elementSetName returns both header+content.
56 Added test for charmap and rusmarc.
58 Added feature charmaps (.chr) so that characters may be specified in
61 Fixed problem with encoding directive for charmap(.chr) files.
63 Allow Remote insert/delete/replace/update with record, recordIdNumber
64 (sysno) and/or recordIdOpaque(user supplied record Id). If both
65 IDs are omitted internal record ID match is assumed (recordId: - in
70 Fix bug. X-Path attribute expressions with spaces in them now works.
72 Fix base address for MARC output.
76 Fix bug with shadow and result set handling.
78 Implement MARCXML to ISO2709 conversion.
82 Add missing examples for Windows install.
84 Fix bug in regx filter to make it "greedy" again. This bug appeared
91 Fix XML error handling. Stop XML parse immediately if XML parse error
92 occur (i.e. produce one error only).
94 Zebra ignores "unsupported use attribute" for individual databases
95 when search multiple databases (unless all databases fail).
97 New filter grs.marcxml which works like grs.marc but produces MARCXML.
99 Added support for database deletion. It is possible to create/drop
100 a database from zebraidx utility. Note: only for isam:b.
102 Write zebrasrv.pid to lockdir.
104 Bug fix: result sets were not recovered correctly. Had to
105 add ODR handle for zebra_search_RPN in order to make it work.
107 Fixed a bug in regx filters that didn't do anchors (^) correctly.
109 Fixed a bug in searches with X-Path searches sometimes giving "extra"
112 Zebra server checks for zebrasrv.pid and refuses to start if it is already
113 locked by another (running) zebrasrv.
115 Fixed a bug with text being chunked in pieces for the grs.xml filter.
117 --- 1.3.11 2003/04/25
119 xelm code updates. xelm works regardless state of 'xpath enable/disable'
120 Avoid -L/usr/lib since that is already default library path.
122 Allow multiple updates within one transaction.
124 Fixed a bug with >2GB files (overflow in integer expression).
126 --- 1.3.10 2003/04/01
128 Fix linker error for Perl module.
130 Fix bug in and operation which in some cases could result in "extra"
131 hits. Bug was introduced in 1.3.5.
133 Fix bug in handling of schema conversion when producing numeric tags.
139 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
143 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
144 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
145 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
147 livrank: another experimental ranking algorithm. Source in livcode.c.
148 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
150 Contributed by Pete Mallinson, University of Liverpool.
152 Advanced MARC indexing. See doc/marc_indexing.xml
153 Oleg Kolobov <oleg at lib.tpu.ru>
155 Perl API updates and fixes.
156 Peter Popovics <pop at technomat.hu>
158 Fixed 'zebraidx delete'.
160 Implemented 'zebraidx clean'.
162 64-bit offsets for register files on WIN32 (no 2 GB limit).
164 Fixed a few memory leaks WRT sorting.
168 Fixed error handling : error code was not properly returned.
170 Support Truncation 104 (CCL).
174 Added missing source files for perl extension.
178 Implemented xelm directive.
180 Updated for newer version of YAZ (introduction of string schema).
182 Directory examples/zthes now part of distribution (was missing
183 in previous release).
185 New .abs directive, systag, that control where to put retrieval
186 information. The directive takes two arguments: system tag, element name.
187 System tag is one of : rank, sysno, size.
191 Perl Filter and Perl API. By Peter Popovics.
193 For zebra.cfg, if no profilePath is specified, directory
194 (prefix)/share/idzebra/tab
197 Zebra Examples in examples . Zebra tests in test.
199 Bug fix: sort index was not properly modified on
200 record updates/deletes.
202 Fix handling of character entities for sgml filter.
204 Move data1 to Zebra (used to be part of YAZ).
208 Fix character encoding of scan response terms.
210 Fix character decoding of scan request terms.
212 Fix ESpec handling (requires YAZ 1.9.1)
214 Fix searches for complete fields.
218 When name zebra is used in a filename or directory 'idzebra' is used
219 instead to avoid confusion with GNU zebra (routing software).
221 Zebra server stops with a fatal error if config file cannot be read.
223 New config setting, followLinks, that controls whether update of files
224 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
225 By default symbolic links are followed.
227 Fix MARC transfer . MARC fields had wrong data for multiple fields.
229 XML record reader moved from YAZ to Zebra, to make YAZ less
230 dependant on external libraries.
232 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
233 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
234 on systems that doesn't offer iconv.
236 XML record reader supports external system entities.
240 New .abs-directive "xpath" that takes one argument: "enable"
241 or "disable" to enable and disable XPath -indexing. If no "xpath"
242 direcive is found in .abs-file , XPath-indexing is disabled to ensure
243 backwards compatibility. For missing .abs-files XPath-indexing is
244 enabled so that such records are searchable.
246 Zebra warns about missing .abs-file only once (for each type).
248 Fixed a bug in file update where already-inserted files could
253 Zebra license changed to GNU GPL.
255 XPath-like queries used when RPN string attributes are used, eg.
256 @attr 1=/portal/title sometitle
257 @attr 1=/portal/title[@xml:lang=da] danishtitle
258 @attr 1=/portal/title/@xml:lang da
259 @attr 1=//title sometitle
261 Zebra uses UTF-8 internally:
262 1) New setting "encoding" for zebra.cfg that specifies encoding for
263 OCTET terms in queries and record encoding for most transfer syntaxes
264 (except those that use International Strings, such as GRS-1).
265 2) The encoding of International strings is UTF-8 by default. It
266 may be changed by character set negotiation. If character set
267 negotiation is in effect and if records are selected for conversion
268 these'll be converted to the selected character set - thus overriding
269 the encoding setting in zebra.cfg.
270 3) New directive "encoding" in .abs-files. This specifies the external
271 character encoding for files indexed by zebra. However, if records
272 themselves have an XML header that specifies and encoding that'll be used
275 XML filter (-t grs.xml).
277 Multiple registers. New setting in resource 'root' that holds base
278 directory for register(s). A group a databases may be put in separate
279 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
283 Fixes for Digital Unix
285 Implemented hits per term using USR:SearchResult-1.
287 New Zebra API. Locking system re-implemented.
289 --- 1.1.stable 2002/02/20
291 Rank weight can be controlled with attribute type 9. Default
292 value is 34. Recommended values between 1-36.
296 Updated for YAZ version 1.8.
298 Added support for termsets - a result set of terms matching
299 a given query. For @attr 8=<set> creates termset named <set>.
301 Added support for raw retrieval. Element Set Name R forces the
302 text filter which returns the record in its original form.
304 Added numerical sort - triggered by structure=numeric (4=109).
306 Remote record import using Z39.50 Extended Services and Segments.
308 Fixed bug where updating a database with user-defined attributes
309 could corrupt the register (bad storeKeys).
311 Multi-threaded version.
313 Fixed bug regarding proximity.
315 Documentation updates.
317 Fixed bug in record retrieval module that occured on 64-bit OSF
322 Fixed bug in makefile for WIN32.
324 Fixed bug in configure script - used bash-specific features.
328 Added support for multiple records in one file for filter grs.sgml.
330 Changed record index structure. New layout is incompatible with
331 previous releases. Added setting "recordcompression" to control
332 compression of records. Possible values are "none" (no
333 compression) and bzip2 (compression using libbz2).
335 Added XML transfer syntax support for retrieval of structured records.
336 Schema in CompSpec is recognised in retrieval of structured records.
338 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
339 that fails, the filter reads the file <filt>.flt (regx style filter).
341 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
342 Zebra's configure script automatically attempts to locate Tcl. For
343 manual Tcl configuration use option --with-tclconfig=<path> to specify
344 where Tcl's library files are located.
346 Implemented "compression" of Dictionary and ISAM system. Dictionary
349 Added "tagsysno" directive to zebra.cfg to control under which tag the
350 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
353 Added "tagrank" as above.
355 Changed file naming scheme for register files from <name>.mf.<no> to
358 Implemented "position"-flag for register type (as defined in
359 default.idx). When set to zero no position (or seqence number) is
360 saved in register for each word occurrence, thus saving some register
363 Implemented database mapping. Using mapdb one can specify a database
364 to be mapped to one or more physical databases. Usage:
365 mapdb <fromdb> <todb> ..
367 Added SOIF-filter. Thanks to Peter Valkenburg.
369 For the regx-filter "end element -record" may trigger a mark-of-record
370 if outer level is reached.
372 Tag sets may be typed in the reference to it. From the .abs-file the
373 "tagset" directive takes a third optional integer type for the tag set
374 referenced. From a .tag-file the "include" directive takes a third
375 optional type as well. The old "type" directive in the tag set itself
376 is still recognized but acts as the default type for the tag set.
378 Zebra supports the specification of arbitrary attributes sets, schemas
379 and tag sets, because of the change in YAZ' OID management system.
381 Fixed bug in Sort that caused it NOT to use character mapping as it
384 Zebra now uses GNU configure to generate Makefile(s).
386 Added un-optimised support for left and left/right truncation attributes.
388 Added support for relational operators on text when using RPN queries.
390 Added support for sort specifications in RPN queries. Type 7 specifies
391 'sort' where value 1=ascending, value 2=descending. The use attribute
392 specifies the field criteria as usual. The term specifies priority
393 where 0=first, 1=second, ...
395 Changed the way use attributes are specified in the recordId
398 Maximum number of databases in one Zebra register increased.
400 New setting, databasePath, which specifies that first directory during
401 update traversal is the database name (instead of a fixed one).
403 New setting, explainDatabase, which specifies that databases are
406 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
408 Implemented EXPLAIN database maintenance. Zebra automatically
409 generate - and update CategoryList, TargetInfo, DatabaseInfo,
410 AttributeSetInfo and AttributeDetails records at this stage. The
411 records may be transferred as GRS-1, SUTRS or Explain.
413 Fixed register spec so that colon isn't treated as size separator
414 unless followed by [0-9+-] in order to allow DOS drive specifications.
416 Fixed two bugs in ISAMC system.
418 Changed the way Zebra keeps its maintenance information about attribute
419 sets, available attributes, etc.. Records in "SGML" notation using an
420 EXPLAIN schema is now used when appropriate.
422 Bug fix: Index didn't handle update/insert/delete of the same record
423 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
424 first occurence of a record is considered.
426 Most searches now return correct number of hits.
428 New modular ranking system. Interested programmers are encouraged to
429 inspect rank1.c and improve the algorithm.
431 Bug fix: Lock files weren't removed as they should on NT.
433 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
434 specify a "sort register". Refer to the gils sample records which refer
435 to index type "s" which is specified as "sort" in the default.idx file.
436 Each sort criteria can either be Ascending or Descending and at most
437 three sort elements can be specified.
439 Bug fix: Character mapping didn't work for text files.
443 Simple ranked searches now return correct number of hits.
445 The test option (-s) only makes a read-lock on the index as well
446 as using read-only operations anywhere.
448 Moved towards generic character mapping. Configuration file default.idx
449 specifies character map files for register types w, p, u, etc.
451 Implemented "begin variant" for the sgml.regx - filter.
453 Fixed a few memory leaks.
455 Added support for C++, headers uses extern "C" for public definitions.
457 Bug fix: The show records facility (-s) only displayed information for
458 the first record in a file (and not for every record in the file).
460 Added option "-f <n>" to limit the logging of record operations. After
461 <n> records has been processed no logging is performed (unless errors
464 Bug fix: the compressed ISAM system didn't handle update operations
467 Added setting, "maxResultSetSize", to hold the number of records to
468 save in a result set.
470 Bug fix: Complete phrase did't work for search operations.
472 Bug fix: temporary result sets weren't deleted.
474 Reduced disk space for saved keys (storeKeys = 1).
476 Added optional, physical ANY (key replication)
478 Implemented proximity operator in search.
480 Bug fix: the path name buffers used by file match traversal routines
481 have been extended to support long file names.
483 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
484 configuration file. The resulting register without "storeKeys" is about
485 half the size, and the memory used by zebraidx during phase 2 (merge) is
486 reduced to a minimum.
488 Reworked the way Regexp-2 queries with error tolerance are handled and
489 specified. The documentation has been updated accordingly.
491 Bug fix: Zebrasrv didn't search correctly when queries contained masking
492 characters. This bug was introduced in 1.0a8.
494 Zebrasrv now tag records with the proper database name.
496 New settings, memMax and keyTmpDir.
498 Changed name of setting lockDir (previously called lockPath) and
499 setTmpDir (previously called tempSetPath).
501 Generalized and changed record type specifications. In short, there are:
503 grs.sgml structured, "SGML-like" syntax
504 grs.regx.<filter> structured, Regular expression filter
505 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
506 is the name of an abstract syntax file.
507 Bug fix: Result sets weren't sorted in operations involving boolean
508 operations with "ranked" operands.
512 Added national character-handling subsystem.
516 Small modifications to input filters and profiles.
518 Added support for SOIF syntax (with private OID).
522 Fixed buffer-size problem in indexing.
524 Added compression to temporary files for updating.
526 Added phrase registers.
528 Added dynamic mapping of search attribute to multiple termlists (ANY).
530 Scan support in multiple databases/registers.
532 Configuration settings are case-insensitive and single dash (-)
533 characters are ignored in comparisons.
535 The index processing ignores empty files - warning given.
537 New option to zebraidx (-V) displays version information.
541 Fixed problem in file-update system.
543 Fixed problem in shadow system; register was sometimes corrupted after
548 Fixed problems in the ISAM subsystem. Caused difficulties when updating
551 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
552 the rank and record number.
554 Fixed bug in the isam subsystem - caused a malfunction when accessing
555 words which occurred more than 10000 times.
557 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
560 Server can now run under inetd. Use option -i, and -w <directory> to
561 set working directory to desired location.
563 New zebraidx command: clean - removes temporary shadow files.
565 Fixed bug in ISAM system. Occurred rarely during register updates.
567 Logging during index merge phase is improved. The remaining running
570 Temporary files generated by zebraidx are removed after each run.
572 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
573 when doing scan operations in dictionaries with European characters.
577 A whole slew of updates, to make the first publicized release. Get the doc
582 Memory-problems in ISAM fixed. More blocktypes added to the default setup
583 to increase performance on larger databases.
585 Various minor changes in data management system.
589 A couple of portability-problems resolved.
591 Changed some malloc() to xmalloc().
