1 Implemented bug #588: allrecords search. Using @attr 1=allrecords ""
2 matches all records in a database.
4 Zebra reads (non-standard) attribute 10 for RPN queries. The value, when
5 specified, is returned as subqueryId in SearchResult-1. It un-specified
6 no subqueryId is part of SearchResult-1.
8 Added 'dbperms' setting to zebra.cfg. Names file with lines of
9 format username: db1+...dbn, listing databases that user has access to.
10 Database-specific access control only happens for searching, at present.
12 Added zebra_set_approx_limit for a ZebraHandle (session). Results
13 will be approximate if hit count is greater than the limit specified.
15 Added support for term hit counts. This was not in place for earlier
16 1.4 versions, but is present in the 1.3 series. Bug #124.
18 Implemented the 'equivalent' directive for .chr-files.
20 Added zebra_get_bfs to get BFile handle for session.
22 Added 'melm' directive to absyn format to simplify config files
23 for MARC-style databases. See tab/marc21.abs for an example.
25 Added bath-compliant definition file marc21.abs for use with MARC databases.
27 Added autoconf utility idzebra.m4 which defines --with-idzebra .
29 Added mechanism to ignore leading articles when doing full-field indexing,
30 based on the character map files. See the manual for further discussion.
32 Fixed bug in record management. Releasing blocks could result in
35 Fixed bug in isam:b. A tree split could result in a lost item.
37 Remove isamd. It's not been in use for a long time and isamb is better
40 Change SYSNO to be zint. Change pointers in isamc and isamb to zint.
41 Change block number in bfile/cfile to zint. zint is a long integer
42 (64-bit). This change practially removes register limits for Zebra.
44 Implement int-list encoding for ISAMs.
46 Added facility to make attibutes in grs.regx and grs.tcl filter using the
47 data command with argument -attribute <name> . The content of data is
48 the value of the attribute. This command should be used inside a
49 begin element , end element section.
51 Update zebra.nsi to NSIS 2.
53 Added a new 'cut' directive to charmaps (.chr files) which specifies that
54 only characters after the cutting char should be indexed.
56 Update Perl internals so that it matches the current Zebra API.
57 The recordGroup structure is no longer available. A group of resources
58 can still be referenced by setting groupName=>.. in various methods.
60 Maximum number of records to be sorted in a result set can be
61 specified by setting "sortmax". Default is 1000.
63 Allow use of string use attributes for regular attribute sets. The
64 name matches the name given in the attribute set file. All strings
65 starting with / are considered X-Path as usual.
67 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
68 element for XML tree. It may only pop off if -record is given.
70 Added grs.danbib filter - for Danish Bibliographic Centre.
72 Rename CHANGELOG to NEWS.
74 For text filter, return only header if elementSetName=H . elementSetName=R
75 returns contents only. Other elementSetName returns both header+content.
77 Added test for charmap and rusmarc.
79 Added feature charmaps (.chr) so that characters may be specified in
82 Fixed problem with encoding directive for charmap(.chr) files.
84 Allow Remote insert/delete/replace/update with record, recordIdNumber
85 (sysno) and/or recordIdOpaque(user supplied record Id). If both
86 IDs are omitted internal record ID match is assumed (recordId: - in
91 Fix bug. X-Path attribute expressions with spaces in them now works.
93 Fix base address for MARC output.
97 Fix bug with shadow and result set handling.
99 Implement MARCXML to ISO2709 conversion.
101 --- 1.3.13 2003/09/26
103 Add missing examples for Windows install.
105 Fix bug in regx filter to make it "greedy" again. This bug appeared
110 --- 1.3.12 2003/09/08
112 Fix XML error handling. Stop XML parse immediately if XML parse error
113 occur (i.e. produce one error only).
115 Zebra ignores "unsupported use attribute" for individual databases
116 when search multiple databases (unless all databases fail).
118 New filter grs.marcxml which works like grs.marc but produces MARCXML.
120 Added support for database deletion. It is possible to create/drop
121 a database from zebraidx utility. Note: only for isam:b.
123 Write zebrasrv.pid to lockdir.
125 Bug fix: result sets were not recovered correctly. Had to
126 add ODR handle for zebra_search_RPN in order to make it work.
128 Fixed a bug in regx filters that didn't do anchors (^) correctly.
130 Fixed a bug in searches with X-Path searches sometimes giving "extra"
133 Zebra server checks for zebrasrv.pid and refuses to start if it is already
134 locked by another (running) zebrasrv.
136 Fixed a bug with text being chunked in pieces for the grs.xml filter.
138 --- 1.3.11 2003/04/25
140 xelm code updates. xelm works regardless state of 'xpath enable/disable'
141 Avoid -L/usr/lib since that is already default library path.
143 Allow multiple updates within one transaction.
145 Fixed a bug with >2GB files (overflow in integer expression).
147 --- 1.3.10 2003/04/01
149 Fix linker error for Perl module.
151 Fix bug in and operation which in some cases could result in "extra"
152 hits. Bug was introduced in 1.3.5.
154 Fix bug in handling of schema conversion when producing numeric tags.
160 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
164 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
165 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
166 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
168 livrank: another experimental ranking algorithm. Source in livcode.c.
169 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
171 Contributed by Pete Mallinson, University of Liverpool.
173 Advanced MARC indexing. See doc/marc_indexing.xml
174 Oleg Kolobov <oleg at lib.tpu.ru>
176 Perl API updates and fixes.
177 Peter Popovics <pop at technomat.hu>
179 Fixed 'zebraidx delete'.
181 Implemented 'zebraidx clean'.
183 64-bit offsets for register files on WIN32 (no 2 GB limit).
185 Fixed a few memory leaks WRT sorting.
189 Fixed error handling : error code was not properly returned.
191 Support Truncation 104 (CCL).
195 Added missing source files for perl extension.
199 Implemented xelm directive.
201 Updated for newer version of YAZ (introduction of string schema).
203 Directory examples/zthes now part of distribution (was missing
204 in previous release).
206 New .abs directive, systag, that control where to put retrieval
207 information. The directive takes two arguments: system tag, element name.
208 System tag is one of : rank, sysno, size.
212 Perl Filter and Perl API. By Peter Popovics.
214 For zebra.cfg, if no profilePath is specified, directory
215 (prefix)/share/idzebra/tab
218 Zebra Examples in examples . Zebra tests in test.
220 Bug fix: sort index was not properly modified on
221 record updates/deletes.
223 Fix handling of character entities for sgml filter.
225 Move data1 to Zebra (used to be part of YAZ).
229 Fix character encoding of scan response terms.
231 Fix character decoding of scan request terms.
233 Fix ESpec handling (requires YAZ 1.9.1)
235 Fix searches for complete fields.
239 When name zebra is used in a filename or directory 'idzebra' is used
240 instead to avoid confusion with GNU zebra (routing software).
242 Zebra server stops with a fatal error if config file cannot be read.
244 New config setting, followLinks, that controls whether update of files
245 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
246 By default symbolic links are followed.
248 Fix MARC transfer . MARC fields had wrong data for multiple fields.
250 XML record reader moved from YAZ to Zebra, to make YAZ less
251 dependant on external libraries.
253 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
254 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
255 on systems that doesn't offer iconv.
257 XML record reader supports external system entities.
261 New .abs-directive "xpath" that takes one argument: "enable"
262 or "disable" to enable and disable XPath -indexing. If no "xpath"
263 direcive is found in .abs-file , XPath-indexing is disabled to ensure
264 backwards compatibility. For missing .abs-files XPath-indexing is
265 enabled so that such records are searchable.
267 Zebra warns about missing .abs-file only once (for each type).
269 Fixed a bug in file update where already-inserted files could
274 Zebra license changed to GNU GPL.
276 XPath-like queries used when RPN string attributes are used, eg.
277 @attr 1=/portal/title sometitle
278 @attr 1=/portal/title[@xml:lang=da] danishtitle
279 @attr 1=/portal/title/@xml:lang da
280 @attr 1=//title sometitle
282 Zebra uses UTF-8 internally:
283 1) New setting "encoding" for zebra.cfg that specifies encoding for
284 OCTET terms in queries and record encoding for most transfer syntaxes
285 (except those that use International Strings, such as GRS-1).
286 2) The encoding of International strings is UTF-8 by default. It
287 may be changed by character set negotiation. If character set
288 negotiation is in effect and if records are selected for conversion
289 these'll be converted to the selected character set - thus overriding
290 the encoding setting in zebra.cfg.
291 3) New directive "encoding" in .abs-files. This specifies the external
292 character encoding for files indexed by zebra. However, if records
293 themselves have an XML header that specifies and encoding that'll be used
296 XML filter (-t grs.xml).
298 Multiple registers. New setting in resource 'root' that holds base
299 directory for register(s). A group a databases may be put in separate
300 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
304 Fixes for Digital Unix
306 Implemented hits per term using USR:SearchResult-1.
308 New Zebra API. Locking system re-implemented.
310 --- 1.1.stable 2002/02/20
312 Rank weight can be controlled with attribute type 9. Default
313 value is 34. Recommended values between 1-36.
317 Updated for YAZ version 1.8.
319 Added support for termsets - a result set of terms matching
320 a given query. For @attr 8=<set> creates termset named <set>.
322 Added support for raw retrieval. Element Set Name R forces the
323 text filter which returns the record in its original form.
325 Added numerical sort - triggered by structure=numeric (4=109).
327 Remote record import using Z39.50 Extended Services and Segments.
329 Fixed bug where updating a database with user-defined attributes
330 could corrupt the register (bad storeKeys).
332 Multi-threaded version.
334 Fixed bug regarding proximity.
336 Documentation updates.
338 Fixed bug in record retrieval module that occured on 64-bit OSF
343 Fixed bug in makefile for WIN32.
345 Fixed bug in configure script - used bash-specific features.
349 Added support for multiple records in one file for filter grs.sgml.
351 Changed record index structure. New layout is incompatible with
352 previous releases. Added setting "recordcompression" to control
353 compression of records. Possible values are "none" (no
354 compression) and bzip2 (compression using libbz2).
356 Added XML transfer syntax support for retrieval of structured records.
357 Schema in CompSpec is recognised in retrieval of structured records.
359 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
360 that fails, the filter reads the file <filt>.flt (regx style filter).
362 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
363 Zebra's configure script automatically attempts to locate Tcl. For
364 manual Tcl configuration use option --with-tclconfig=<path> to specify
365 where Tcl's library files are located.
367 Implemented "compression" of Dictionary and ISAM system. Dictionary
370 Added "tagsysno" directive to zebra.cfg to control under which tag the
371 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
374 Added "tagrank" as above.
376 Changed file naming scheme for register files from <name>.mf.<no> to
379 Implemented "position"-flag for register type (as defined in
380 default.idx). When set to zero no position (or seqence number) is
381 saved in register for each word occurrence, thus saving some register
384 Implemented database mapping. Using mapdb one can specify a database
385 to be mapped to one or more physical databases. Usage:
386 mapdb <fromdb> <todb> ..
388 Added SOIF-filter. Thanks to Peter Valkenburg.
390 For the regx-filter "end element -record" may trigger a mark-of-record
391 if outer level is reached.
393 Tag sets may be typed in the reference to it. From the .abs-file the
394 "tagset" directive takes a third optional integer type for the tag set
395 referenced. From a .tag-file the "include" directive takes a third
396 optional type as well. The old "type" directive in the tag set itself
397 is still recognized but acts as the default type for the tag set.
399 Zebra supports the specification of arbitrary attributes sets, schemas
400 and tag sets, because of the change in YAZ' OID management system.
402 Fixed bug in Sort that caused it NOT to use character mapping as it
405 Zebra now uses GNU configure to generate Makefile(s).
407 Added un-optimised support for left and left/right truncation attributes.
409 Added support for relational operators on text when using RPN queries.
411 Added support for sort specifications in RPN queries. Type 7 specifies
412 'sort' where value 1=ascending, value 2=descending. The use attribute
413 specifies the field criteria as usual. The term specifies priority
414 where 0=first, 1=second, ...
416 Changed the way use attributes are specified in the recordId
419 Maximum number of databases in one Zebra register increased.
421 New setting, databasePath, which specifies that first directory during
422 update traversal is the database name (instead of a fixed one).
424 New setting, explainDatabase, which specifies that databases are
427 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
429 Implemented EXPLAIN database maintenance. Zebra automatically
430 generate - and update CategoryList, TargetInfo, DatabaseInfo,
431 AttributeSetInfo and AttributeDetails records at this stage. The
432 records may be transferred as GRS-1, SUTRS or Explain.
434 Fixed register spec so that colon isn't treated as size separator
435 unless followed by [0-9+-] in order to allow DOS drive specifications.
437 Fixed two bugs in ISAMC system.
439 Changed the way Zebra keeps its maintenance information about attribute
440 sets, available attributes, etc.. Records in "SGML" notation using an
441 EXPLAIN schema is now used when appropriate.
443 Bug fix: Index didn't handle update/insert/delete of the same record
444 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
445 first occurence of a record is considered.
447 Most searches now return correct number of hits.
449 New modular ranking system. Interested programmers are encouraged to
450 inspect rank1.c and improve the algorithm.
452 Bug fix: Lock files weren't removed as they should on NT.
454 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
455 specify a "sort register". Refer to the gils sample records which refer
456 to index type "s" which is specified as "sort" in the default.idx file.
457 Each sort criteria can either be Ascending or Descending and at most
458 three sort elements can be specified.
460 Bug fix: Character mapping didn't work for text files.
464 Simple ranked searches now return correct number of hits.
466 The test option (-s) only makes a read-lock on the index as well
467 as using read-only operations anywhere.
469 Moved towards generic character mapping. Configuration file default.idx
470 specifies character map files for register types w, p, u, etc.
472 Implemented "begin variant" for the sgml.regx - filter.
474 Fixed a few memory leaks.
476 Added support for C++, headers uses extern "C" for public definitions.
478 Bug fix: The show records facility (-s) only displayed information for
479 the first record in a file (and not for every record in the file).
481 Added option "-f <n>" to limit the logging of record operations. After
482 <n> records has been processed no logging is performed (unless errors
485 Bug fix: the compressed ISAM system didn't handle update operations
488 Added setting, "maxResultSetSize", to hold the number of records to
489 save in a result set.
491 Bug fix: Complete phrase did't work for search operations.
493 Bug fix: temporary result sets weren't deleted.
495 Reduced disk space for saved keys (storeKeys = 1).
497 Added optional, physical ANY (key replication)
499 Implemented proximity operator in search.
501 Bug fix: the path name buffers used by file match traversal routines
502 have been extended to support long file names.
504 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
505 configuration file. The resulting register without "storeKeys" is about
506 half the size, and the memory used by zebraidx during phase 2 (merge) is
507 reduced to a minimum.
509 Reworked the way Regexp-2 queries with error tolerance are handled and
510 specified. The documentation has been updated accordingly.
512 Bug fix: Zebrasrv didn't search correctly when queries contained masking
513 characters. This bug was introduced in 1.0a8.
515 Zebrasrv now tag records with the proper database name.
517 New settings, memMax and keyTmpDir.
519 Changed name of setting lockDir (previously called lockPath) and
520 setTmpDir (previously called tempSetPath).
522 Generalized and changed record type specifications. In short, there are:
524 grs.sgml structured, "SGML-like" syntax
525 grs.regx.<filter> structured, Regular expression filter
526 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
527 is the name of an abstract syntax file.
528 Bug fix: Result sets weren't sorted in operations involving boolean
529 operations with "ranked" operands.
533 Added national character-handling subsystem.
537 Small modifications to input filters and profiles.
539 Added support for SOIF syntax (with private OID).
543 Fixed buffer-size problem in indexing.
545 Added compression to temporary files for updating.
547 Added phrase registers.
549 Added dynamic mapping of search attribute to multiple termlists (ANY).
551 Scan support in multiple databases/registers.
553 Configuration settings are case-insensitive and single dash (-)
554 characters are ignored in comparisons.
556 The index processing ignores empty files - warning given.
558 New option to zebraidx (-V) displays version information.
562 Fixed problem in file-update system.
564 Fixed problem in shadow system; register was sometimes corrupted after
569 Fixed problems in the ISAM subsystem. Caused difficulties when updating
572 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
573 the rank and record number.
575 Fixed bug in the isam subsystem - caused a malfunction when accessing
576 words which occurred more than 10000 times.
578 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
581 Server can now run under inetd. Use option -i, and -w <directory> to
582 set working directory to desired location.
584 New zebraidx command: clean - removes temporary shadow files.
586 Fixed bug in ISAM system. Occurred rarely during register updates.
588 Logging during index merge phase is improved. The remaining running
591 Temporary files generated by zebraidx are removed after each run.
593 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
594 when doing scan operations in dictionaries with European characters.
598 A whole slew of updates, to make the first publicized release. Get the doc
603 Memory-problems in ISAM fixed. More blocktypes added to the default setup
604 to increase performance on larger databases.
606 Various minor changes in data management system.
610 A couple of portability-problems resolved.
612 Changed some malloc() to xmalloc().
