4 Documented authentication facility in Zebra. Added zebra.cfg directive
5 'passwd.c' which specifies user accounts file with encrypted passwords. The
6 directive 'passwd' specifies user accounts file with clear-text passwords.
7 The previous version of Zebra used plain/clear text depending on
8 configuration automatically. That caused upgrade trouble. Bug #356.
12 Depend on YAZ 2.0.18 or later in configure.
14 Fixed crash that could occur if ES update transaction failed.
16 Configure enables the use of the crypt API - if available.
18 Fixed bug #304: Fuzzy search regExpr-2 did not use proper error distance
21 Fixed bug #305: Scan now handles negative preferred-position-in-response.
23 Implemented the 'equivalent' directive for .chr-files.
27 For configure, support threading again. It was removed by mistake
30 Fixed bug #262: spaces in control fields in MARC returned.
32 Fixed bug #259: Second indicator lost in MARC records
36 Fixed bug #253: Setting group.database not honored
38 Fixed bug #252: Sort does not work.
40 Fixed bug #248: hit counts in combinatoric (and) searches in specific ..
44 Fixed bug #248: hit counts in combinatoric (and) searches in specific ..
46 Fixed bug #245: Time for getting records changes a lot based on record
49 Fixed bug #235: weird x-path results.
51 Avoid crash in ISAMB when isamb_pp_open gets ISAMB_POS = 0. In
52 this case EOF (no entries) is signalled. It fixes problem with
53 terms being deleted. See bug #109.
55 Fixed bug #169: Phrase term counts does not work. The bug exists in
58 Added mechanism to ignore leading articles when doing full-field indexing,
59 based on the character map files. See the manual for further discussion.
63 Fixed bug in record management. Releasing blocks could result in
66 Fixed bug in isam:b. A tree split could result in a lost item.
70 Add IDZebra.i to dist so that Perl extension builds again.
74 Added facility to make attibutes in grs.regx and grs.tcl filter using the
75 data command with argument -attribute <name> . The content of data is
76 the value of the attribute. This command should be used inside a
77 begin element , end element section.
79 Update zebra.nsi to NSIS 2.
81 Added a new 'cut' directive to charmaps (.chr files) which specifies that
82 only characters after the cutting char should be indexed.
84 Update Perl internals so that it matches the current Zebra API.
85 The recordGroup structure is no longer available. A group of resources
86 can still be referenced by setting groupName=>.. in various methods.
88 Maximum number of records to be sorted in a result set can be
89 specified by setting "sortmax". Default is 1000.
91 Allow use of string use attributes for regular attribute sets. The
92 name matches the name given in the attribute set file. All strings
93 starting with / are considered X-Path as usual.
95 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
96 element for XML tree. It may only pop off if -record is given.
98 Added grs.danbib filter - for Danish Bibliographic Centre.
100 Rename CHANGELOG to NEWS.
102 For text filter, return only header if elementSetName=H . elementSetName=R
103 returns contents only. Other elementSetName returns both header+content.
105 Added test for charmap and rusmarc.
107 Added feature charmaps (.chr) so that characters may be specified in
110 Fixed problem with encoding directive for charmap(.chr) files.
112 Allow Remote insert/delete/replace/update with record, recordIdNumber
113 (sysno) and/or recordIdOpaque(user supplied record Id). If both
114 IDs are omitted internal record ID match is assumed (recordId: - in
117 --- 1.3.15 2004/01/15

127 Implement MARCXML to ISO2709 conversion.
129 --- 1.3.13 2003/09/26
131 Add missing examples for Windows install.
133 Fix bug in regx filter to make it "greedy" again. This bug appeared
138 --- 1.3.12 2003/09/08
140 Fix XML error handling. Stop XML parse immediately if XML parse error
141 occur (i.e. produce one error only).
143 Zebra ignores "unsupported use attribute" for individual databases
144 when search multiple databases (unless all databases fail).
146 New filter grs.marcxml which works like grs.marc but produces MARCXML.
148 Added support for database deletion. It is possible to create/drop
149 a database from zebraidx utility. Note: only for isam:b.
151 Write zebrasrv.pid to lockdir.
153 Bug fix: result sets were not recovered correctly. Had to
154 add ODR handle for zebra_search_RPN in order to make it work.
156 Fixed a bug in regx filters that didn't do anchors (^) correctly.
158 Fixed a bug in searches with X-Path searches sometimes giving "extra"
161 Zebra server checks for zebrasrv.pid and refuses to start if it is already
162 locked by another (running) zebrasrv.
164 Fixed a bug with text being chunked in pieces for the grs.xml filter.
166 --- 1.3.11 2003/04/25
168 xelm code updates. xelm works regardless state of 'xpath enable/disable'
169 Avoid -L/usr/lib since that is already default library path.
171 Allow multiple updates within one transaction.
173 Fixed a bug with >2GB files (overflow in integer expression).
175 --- 1.3.10 2003/04/01
177 Fix linker error for Perl module.
179 Fix bug in and operation which in some cases could result in "extra"
180 hits. Bug was introduced in 1.3.5.
182 Fix bug in handling of schema conversion when producing numeric tags.
188 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
192 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
193 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
194 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
196 livrank: another experimental ranking algorithm. Source in livcode.c.
197 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
199 Contributed by Pete Mallinson, University of Liverpool.
201 Advanced MARC indexing. See doc/marc_indexing.xml
202 Oleg Kolobov <oleg at lib.tpu.ru>
204 Perl API updates and fixes.
205 Peter Popovics <pop at technomat.hu>
207 Fixed 'zebraidx delete'.
209 Implemented 'zebraidx clean'.
211 64-bit offsets for register files on WIN32 (no 2 GB limit).
213 Fixed a few memory leaks WRT sorting.
217 Fixed error handling : error code was not properly returned.
219 Support Truncation 104 (CCL).
223 Added missing source files for perl extension.
227 Implemented xelm directive.
229 Updated for newer version of YAZ (introduction of string schema).
231 Directory examples/zthes now part of distribution (was missing
232 in previous release).
234 New .abs directive, systag, that control where to put retrieval
235 information. The directive takes two arguments: system tag, element name.
236 System tag is one of : rank, sysno, size.
240 Perl Filter and Perl API. By Peter Popovics.
242 For zebra.cfg, if no profilePath is specified, directory
243 (prefix)/share/idzebra/tab
246 Zebra Examples in examples . Zebra tests in test.
248 Bug fix: sort index was not properly modified on
249 record updates/deletes.
251 Fix handling of character entities for sgml filter.
253 Move data1 to Zebra (used to be part of YAZ).
257 Fix character encoding of scan response terms.
259 Fix character decoding of scan request terms.
261 Fix ESpec handling (requires YAZ 1.9.1)
263 Fix searches for complete fields.
267 When name zebra is used in a filename or directory 'idzebra' is used
268 instead to avoid confusion with GNU zebra (routing software).
270 Zebra server stops with a fatal error if config file cannot be read.
272 New config setting, followLinks, that controls whether update of files
273 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
274 By default symbolic links are followed.
276 Fix MARC transfer . MARC fields had wrong data for multiple fields.
278 XML record reader moved from YAZ to Zebra, to make YAZ less
279 dependant on external libraries.
281 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
282 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
283 on systems that doesn't offer iconv.
285 XML record reader supports external system entities.
289 New .abs-directive "xpath" that takes one argument: "enable"
290 or "disable" to enable and disable XPath -indexing. If no "xpath"
291 direcive is found in .abs-file , XPath-indexing is disabled to ensure
292 backwards compatibility. For missing .abs-files XPath-indexing is
293 enabled so that such records are searchable.
295 Zebra warns about missing .abs-file only once (for each type).
297 Fixed a bug in file update where already-inserted files could
302 Zebra license changed to GNU GPL.
304 XPath-like queries used when RPN string attributes are used, eg.
305 @attr 1=/portal/title sometitle
306 @attr 1=/portal/title[@xml:lang=da] danishtitle
307 @attr 1=/portal/title/@xml:lang da
308 @attr 1=//title sometitle
310 Zebra uses UTF-8 internally:
311 1) New setting "encoding" for zebra.cfg that specifies encoding for
312 OCTET terms in queries and record encoding for most transfer syntaxes
313 (except those that use International Strings, such as GRS-1).
314 2) The encoding of International strings is UTF-8 by default. It
315 may be changed by character set negotiation. If character set
316 negotiation is in effect and if records are selected for conversion
317 these'll be converted to the selected character set - thus overriding
318 the encoding setting in zebra.cfg.
319 3) New directive "encoding" in .abs-files. This specifies the external
320 character encoding for files indexed by zebra. However, if records
321 themselves have an XML header that specifies and encoding that'll be used
324 XML filter (-t grs.xml).
326 Multiple registers. New setting in resource 'root' that holds base
327 directory for register(s). A group a databases may be put in separate
328 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
332 Fixes for Digital Unix
334 Implemented hits per term using USR:SearchResult-1.
336 New Zebra API. Locking system re-implemented.
338 --- 1.1.stable 2002/02/20
340 Rank weight can be controlled with attribute type 9. Default
341 value is 34. Recommended values between 1-36.
345 Updated for YAZ version 1.8.
347 Added support for termsets - a result set of terms matching
348 a given query. For @attr 8=<set> creates termset named <set>.
350 Added support for raw retrieval. Element Set Name R forces the
351 text filter which returns the record in its original form.
353 Added numerical sort - triggered by structure=numeric (4=109).
355 Remote record import using Z39.50 Extended Services and Segments.
357 Fixed bug where updating a database with user-defined attributes
358 could corrupt the register (bad storeKeys).
360 Multi-threaded version.
362 Fixed bug regarding proximity.
364 Documentation updates.
366 Fixed bug in record retrieval module that occured on 64-bit OSF
371 Fixed bug in makefile for WIN32.
373 Fixed bug in configure script - used bash-specific features.
377 Added support for multiple records in one file for filter grs.sgml.
379 Changed record index structure. New layout is incompatible with
380 previous releases. Added setting "recordcompression" to control
381 compression of records. Possible values are "none" (no
382 compression) and bzip2 (compression using libbz2).
384 Added XML transfer syntax support for retrieval of structured records.
385 Schema in CompSpec is recognised in retrieval of structured records.
387 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
388 that fails, the filter reads the file <filt>.flt (regx style filter).
390 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
391 Zebra's configure script automatically attempts to locate Tcl. For
392 manual Tcl configuration use option --with-tclconfig=<path> to specify
393 where Tcl's library files are located.
395 Implemented "compression" of Dictionary and ISAM system. Dictionary
398 Added "tagsysno" directive to zebra.cfg to control under which tag the
399 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
402 Added "tagrank" as above.
404 Changed file naming scheme for register files from <name>.mf.<no> to
407 Implemented "position"-flag for register type (as defined in
408 default.idx). When set to zero no position (or seqence number) is
409 saved in register for each word occurrence, thus saving some register
412 Implemented database mapping. Using mapdb one can specify a database
413 to be mapped to one or more physical databases. Usage:
414 mapdb <fromdb> <todb> ..
416 Added SOIF-filter. Thanks to Peter Valkenburg.
418 For the regx-filter "end element -record" may trigger a mark-of-record
419 if outer level is reached.
421 Tag sets may be typed in the reference to it. From the .abs-file the
422 "tagset" directive takes a third optional integer type for the tag set
423 referenced. From a .tag-file the "include" directive takes a third
424 optional type as well. The old "type" directive in the tag set itself
425 is still recognized but acts as the default type for the tag set.
427 Zebra supports the specification of arbitrary attributes sets, schemas
428 and tag sets, because of the change in YAZ' OID management system.
430 Fixed bug in Sort that caused it NOT to use character mapping as it
433 Zebra now uses GNU configure to generate Makefile(s).
435 Added un-optimised support for left and left/right truncation attributes.
437 Added support for relational operators on text when using RPN queries.
439 Added support for sort specifications in RPN queries. Type 7 specifies
440 'sort' where value 1=ascending, value 2=descending. The use attribute
441 specifies the field criteria as usual. The term specifies priority
442 where 0=first, 1=second, ...
444 Changed the way use attributes are specified in the recordId
447 Maximum number of databases in one Zebra register increased.
449 New setting, databasePath, which specifies that first directory during
450 update traversal is the database name (instead of a fixed one).
452 New setting, explainDatabase, which specifies that databases are
455 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
457 Implemented EXPLAIN database maintenance. Zebra automatically
458 generate - and update CategoryList, TargetInfo, DatabaseInfo,
459 AttributeSetInfo and AttributeDetails records at this stage. The
460 records may be transferred as GRS-1, SUTRS or Explain.
462 Fixed register spec so that colon isn't treated as size separator
463 unless followed by [0-9+-] in order to allow DOS drive specifications.
465 Fixed two bugs in ISAMC system.
467 Changed the way Zebra keeps its maintenance information about attribute
468 sets, available attributes, etc.. Records in "SGML" notation using an
469 EXPLAIN schema is now used when appropriate.
471 Bug fix: Index didn't handle update/insert/delete of the same record
472 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
473 first occurence of a record is considered.
475 Most searches now return correct number of hits.
477 New modular ranking system. Interested programmers are encouraged to
478 inspect rank1.c and improve the algorithm.
480 Bug fix: Lock files weren't removed as they should on NT.
482 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
483 specify a "sort register". Refer to the gils sample records which refer
484 to index type "s" which is specified as "sort" in the default.idx file.
485 Each sort criteria can either be Ascending or Descending and at most
486 three sort elements can be specified.
488 Bug fix: Character mapping didn't work for text files.
492 Simple ranked searches now return correct number of hits.
494 The test option (-s) only makes a read-lock on the index as well
495 as using read-only operations anywhere.
497 Moved towards generic character mapping. Configuration file default.idx
498 specifies character map files for register types w, p, u, etc.
500 Implemented "begin variant" for the sgml.regx - filter.
502 Fixed a few memory leaks.
504 Added support for C++, headers uses extern "C" for public definitions.
506 Bug fix: The show records facility (-s) only displayed information for
507 the first record in a file (and not for every record in the file).
509 Added option "-f <n>" to limit the logging of record operations. After
510 <n> records has been processed no logging is performed (unless errors
513 Bug fix: the compressed ISAM system didn't handle update operations
516 Added setting, "maxResultSetSize", to hold the number of records to
517 save in a result set.
519 Bug fix: Complete phrase did't work for search operations.
521 Bug fix: temporary result sets weren't deleted.
523 Reduced disk space for saved keys (storeKeys = 1).
525 Added optional, physical ANY (key replication)
527 Implemented proximity operator in search.
529 Bug fix: the path name buffers used by file match traversal routines
530 have been extended to support long file names.
532 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
533 configuration file. The resulting register without "storeKeys" is about
534 half the size, and the memory used by zebraidx during phase 2 (merge) is
535 reduced to a minimum.
537 Reworked the way Regexp-2 queries with error tolerance are handled and
538 specified. The documentation has been updated accordingly.
540 Bug fix: Zebrasrv didn't search correctly when queries contained masking
541 characters. This bug was introduced in 1.0a8.
543 Zebrasrv now tag records with the proper database name.
545 New settings, memMax and keyTmpDir.
547 Changed name of setting lockDir (previously called lockPath) and
548 setTmpDir (previously called tempSetPath).
550 Generalized and changed record type specifications. In short, there are:
552 grs.sgml structured, "SGML-like" syntax
553 grs.regx.<filter> structured, Regular expression filter
554 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
555 is the name of an abstract syntax file.
556 Bug fix: Result sets weren't sorted in operations involving boolean
557 operations with "ranked" operands.
561 Added national character-handling subsystem.
565 Small modifications to input filters and profiles.
567 Added support for SOIF syntax (with private OID).
571 Fixed buffer-size problem in indexing.
573 Added compression to temporary files for updating.
575 Added phrase registers.
577 Added dynamic mapping of search attribute to multiple termlists (ANY).
579 Scan support in multiple databases/registers.
581 Configuration settings are case-insensitive and single dash (-)
582 characters are ignored in comparisons.
584 The index processing ignores empty files - warning given.
586 New option to zebraidx (-V) displays version information.
590 Fixed problem in file-update system.
592 Fixed problem in shadow system; register was sometimes corrupted after
597 Fixed problems in the ISAM subsystem. Caused difficulties when updating
600 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
601 the rank and record number.
603 Fixed bug in the isam subsystem - caused a malfunction when accessing
604 words which occurred more than 10000 times.
606 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
609 Server can now run under inetd. Use option -i, and -w <directory> to
610 set working directory to desired location.
612 New zebraidx command: clean - removes temporary shadow files.
614 Fixed bug in ISAM system. Occurred rarely during register updates.
616 Logging during index merge phase is improved. The remaining running
619 Temporary files generated by zebraidx are removed after each run.
621 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
622 when doing scan operations in dictionaries with European characters.
626 A whole slew of updates, to make the first publicized release. Get the doc
631 Memory-problems in ISAM fixed. More blocktypes added to the default setup
632 to increase performance on larger databases.
634 Various minor changes in data management system.
638 A couple of portability-problems resolved.
640 Changed some malloc() to xmalloc().
