2 Added support for special slement set _sysno_ which returns a
3 record ID for a record packed as a SUTRS record.
7 Documented authentication facility in Zebra. Added zebra.cfg directive
8 'passwd.c' which specifies user accounts file with encrypted passwords. The
9 directive 'passwd' specifies user accounts file with clear-text passwords.
10 The previous version of Zebra used plain/clear text depending on
11 configuration automatically. That caused upgrade trouble. Bug #356.
15 Depend on YAZ 2.0.18 or later in configure.
17 Fixed crash that could occur if ES update transaction failed.
19 Configure enables the use of the crypt API - if available.

39 Fixed bug #253: Setting group.database not honored
41 Fixed bug #252: Sort does not work.
43 Fixed bug #248: hit counts in combinatoric (and) searches in specific ..
47 Fixed bug #248: hit counts in combinatoric (and) searches in specific ..
49 Fixed bug #245: Time for getting records changes a lot based on record
52 Fixed bug #235: weird x-path results.
54 Avoid crash in ISAMB when isamb_pp_open gets ISAMB_POS = 0. In
55 this case EOF (no entries) is signalled. It fixes problem with
56 terms being deleted. See bug #109.
58 Fixed bug #169: Phrase term counts does not work. The bug exists in
61 Added mechanism to ignore leading articles when doing full-field indexing,
62 based on the character map files. See the manual for further discussion.
66 Fixed bug in record management. Releasing blocks could result in
69 Fixed bug in isam:b. A tree split could result in a lost item.
73 Add IDZebra.i to dist so that Perl extension builds again.
77 Added facility to make attibutes in grs.regx and grs.tcl filter using the
78 data command with argument -attribute <name> . The content of data is
79 the value of the attribute. This command should be used inside a
80 begin element , end element section.
82 Update zebra.nsi to NSIS 2.
84 Added a new 'cut' directive to charmaps (.chr files) which specifies that
85 only characters after the cutting char should be indexed.
87 Update Perl internals so that it matches the current Zebra API.
88 The recordGroup structure is no longer available. A group of resources
89 can still be referenced by setting groupName=>.. in various methods.
91 Maximum number of records to be sorted in a result set can be
92 specified by setting "sortmax". Default is 1000.
94 Allow use of string use attributes for regular attribute sets. The
95 name matches the name given in the attribute set file. All strings
96 starting with / are considered X-Path as usual.
98 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
99 element for XML tree. It may only pop off if -record is given.
101 Added grs.danbib filter - for Danish Bibliographic Centre.
103 Rename CHANGELOG to NEWS.
105 For text filter, return only header if elementSetName=H . elementSetName=R
106 returns contents only. Other elementSetName returns both header+content.
108 Added test for charmap and rusmarc.
110 Added feature charmaps (.chr) so that characters may be specified in
113 Fixed problem with encoding directive for charmap(.chr) files.
115 Allow Remote insert/delete/replace/update with record, recordIdNumber
116 (sysno) and/or recordIdOpaque(user supplied record Id). If both
117 IDs are omitted internal record ID match is assumed (recordId: - in
120 --- 1.3.15 2004/01/15

126 --- 1.3.14 2003/11/29
128 Fix bug with shadow and result set handling.
130 Implement MARCXML to ISO2709 conversion.
132 --- 1.3.13 2003/09/26
134 Add missing examples for Windows install.
136 Fix bug in regx filter to make it "greedy" again. This bug appeared
141 --- 1.3.12 2003/09/08
143 Fix XML error handling. Stop XML parse immediately if XML parse error
144 occur (i.e. produce one error only).
146 Zebra ignores "unsupported use attribute" for individual databases
147 when search multiple databases (unless all databases fail).
149 New filter grs.marcxml which works like grs.marc but produces MARCXML.
151 Added support for database deletion. It is possible to create/drop
152 a database from zebraidx utility. Note: only for isam:b.
154 Write zebrasrv.pid to lockdir.
156 Bug fix: result sets were not recovered correctly. Had to
157 add ODR handle for zebra_search_RPN in order to make it work.
159 Fixed a bug in regx filters that didn't do anchors (^) correctly.
161 Fixed a bug in searches with X-Path searches sometimes giving "extra"
164 Zebra server checks for zebrasrv.pid and refuses to start if it is already
165 locked by another (running) zebrasrv.
167 Fixed a bug with text being chunked in pieces for the grs.xml filter.
169 --- 1.3.11 2003/04/25
171 xelm code updates. xelm works regardless state of 'xpath enable/disable'
172 Avoid -L/usr/lib since that is already default library path.
174 Allow multiple updates within one transaction.
176 Fixed a bug with >2GB files (overflow in integer expression).
178 --- 1.3.10 2003/04/01
180 Fix linker error for Perl module.
182 Fix bug in and operation which in some cases could result in "extra"
183 hits. Bug was introduced in 1.3.5.
185 Fix bug in handling of schema conversion when producing numeric tags.
191 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
195 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
196 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
197 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
199 livrank: another experimental ranking algorithm. Source in livcode.c.
200 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
202 Contributed by Pete Mallinson, University of Liverpool.
204 Advanced MARC indexing. See doc/marc_indexing.xml
205 Oleg Kolobov <oleg at lib.tpu.ru>
207 Perl API updates and fixes.
208 Peter Popovics <pop at technomat.hu>
210 Fixed 'zebraidx delete'.
212 Implemented 'zebraidx clean'.
214 64-bit offsets for register files on WIN32 (no 2 GB limit).
216 Fixed a few memory leaks WRT sorting.
220 Fixed error handling : error code was not properly returned.
222 Support Truncation 104 (CCL).
226 Added missing source files for perl extension.
230 Implemented xelm directive.
232 Updated for newer version of YAZ (introduction of string schema).
234 Directory examples/zthes now part of distribution (was missing
235 in previous release).
237 New .abs directive, systag, that control where to put retrieval
238 information. The directive takes two arguments: system tag, element name.
239 System tag is one of : rank, sysno, size.
243 Perl Filter and Perl API. By Peter Popovics.
245 For zebra.cfg, if no profilePath is specified, directory
246 (prefix)/share/idzebra/tab
249 Zebra Examples in examples . Zebra tests in test.
251 Bug fix: sort index was not properly modified on
252 record updates/deletes.
254 Fix handling of character entities for sgml filter.
256 Move data1 to Zebra (used to be part of YAZ).
260 Fix character encoding of scan response terms.
262 Fix character decoding of scan request terms.
264 Fix ESpec handling (requires YAZ 1.9.1)
266 Fix searches for complete fields.
270 When name zebra is used in a filename or directory 'idzebra' is used
271 instead to avoid confusion with GNU zebra (routing software).
273 Zebra server stops with a fatal error if config file cannot be read.
275 New config setting, followLinks, that controls whether update of files
276 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
277 By default symbolic links are followed.
279 Fix MARC transfer . MARC fields had wrong data for multiple fields.
281 XML record reader moved from YAZ to Zebra, to make YAZ less
282 dependant on external libraries.
284 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
285 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
286 on systems that doesn't offer iconv.
288 XML record reader supports external system entities.
292 New .abs-directive "xpath" that takes one argument: "enable"
293 or "disable" to enable and disable XPath -indexing. If no "xpath"
294 direcive is found in .abs-file , XPath-indexing is disabled to ensure
295 backwards compatibility. For missing .abs-files XPath-indexing is
296 enabled so that such records are searchable.
298 Zebra warns about missing .abs-file only once (for each type).
300 Fixed a bug in file update where already-inserted files could
305 Zebra license changed to GNU GPL.
307 XPath-like queries used when RPN string attributes are used, eg.
308 @attr 1=/portal/title sometitle
309 @attr 1=/portal/title[@xml:lang=da] danishtitle
310 @attr 1=/portal/title/@xml:lang da
311 @attr 1=//title sometitle
313 Zebra uses UTF-8 internally:
314 1) New setting "encoding" for zebra.cfg that specifies encoding for
315 OCTET terms in queries and record encoding for most transfer syntaxes
316 (except those that use International Strings, such as GRS-1).
317 2) The encoding of International strings is UTF-8 by default. It
318 may be changed by character set negotiation. If character set
319 negotiation is in effect and if records are selected for conversion
320 these'll be converted to the selected character set - thus overriding
321 the encoding setting in zebra.cfg.
322 3) New directive "encoding" in .abs-files. This specifies the external
323 character encoding for files indexed by zebra. However, if records
324 themselves have an XML header that specifies and encoding that'll be used
327 XML filter (-t grs.xml).
329 Multiple registers. New setting in resource 'root' that holds base
330 directory for register(s). A group a databases may be put in separate
331 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
335 Fixes for Digital Unix
337 Implemented hits per term using USR:SearchResult-1.
339 New Zebra API. Locking system re-implemented.
341 --- 1.1.stable 2002/02/20
343 Rank weight can be controlled with attribute type 9. Default
344 value is 34. Recommended values between 1-36.
348 Updated for YAZ version 1.8.
350 Added support for termsets - a result set of terms matching
351 a given query. For @attr 8=<set> creates termset named <set>.
353 Added support for raw retrieval. Element Set Name R forces the
354 text filter which returns the record in its original form.
356 Added numerical sort - triggered by structure=numeric (4=109).
358 Remote record import using Z39.50 Extended Services and Segments.
360 Fixed bug where updating a database with user-defined attributes
361 could corrupt the register (bad storeKeys).
363 Multi-threaded version.
365 Fixed bug regarding proximity.
367 Documentation updates.
369 Fixed bug in record retrieval module that occured on 64-bit OSF
374 Fixed bug in makefile for WIN32.
376 Fixed bug in configure script - used bash-specific features.
380 Added support for multiple records in one file for filter grs.sgml.
382 Changed record index structure. New layout is incompatible with
383 previous releases. Added setting "recordcompression" to control
384 compression of records. Possible values are "none" (no
385 compression) and bzip2 (compression using libbz2).
387 Added XML transfer syntax support for retrieval of structured records.
388 Schema in CompSpec is recognised in retrieval of structured records.
390 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
391 that fails, the filter reads the file <filt>.flt (regx style filter).
393 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
394 Zebra's configure script automatically attempts to locate Tcl. For
395 manual Tcl configuration use option --with-tclconfig=<path> to specify
396 where Tcl's library files are located.
398 Implemented "compression" of Dictionary and ISAM system. Dictionary
401 Added "tagsysno" directive to zebra.cfg to control under which tag the
402 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
405 Added "tagrank" as above.
407 Changed file naming scheme for register files from <name>.mf.<no> to
410 Implemented "position"-flag for register type (as defined in
411 default.idx). When set to zero no position (or seqence number) is
412 saved in register for each word occurrence, thus saving some register
415 Implemented database mapping. Using mapdb one can specify a database
416 to be mapped to one or more physical databases. Usage:
417 mapdb <fromdb> <todb> ..
419 Added SOIF-filter. Thanks to Peter Valkenburg.
421 For the regx-filter "end element -record" may trigger a mark-of-record
422 if outer level is reached.
424 Tag sets may be typed in the reference to it. From the .abs-file the
425 "tagset" directive takes a third optional integer type for the tag set
426 referenced. From a .tag-file the "include" directive takes a third
427 optional type as well. The old "type" directive in the tag set itself
428 is still recognized but acts as the default type for the tag set.
430 Zebra supports the specification of arbitrary attributes sets, schemas
431 and tag sets, because of the change in YAZ' OID management system.
433 Fixed bug in Sort that caused it NOT to use character mapping as it
436 Zebra now uses GNU configure to generate Makefile(s).
438 Added un-optimised support for left and left/right truncation attributes.
440 Added support for relational operators on text when using RPN queries.
442 Added support for sort specifications in RPN queries. Type 7 specifies
443 'sort' where value 1=ascending, value 2=descending. The use attribute
444 specifies the field criteria as usual. The term specifies priority
445 where 0=first, 1=second, ...
447 Changed the way use attributes are specified in the recordId
450 Maximum number of databases in one Zebra register increased.
452 New setting, databasePath, which specifies that first directory during
453 update traversal is the database name (instead of a fixed one).
455 New setting, explainDatabase, which specifies that databases are
458 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
460 Implemented EXPLAIN database maintenance. Zebra automatically
461 generate - and update CategoryList, TargetInfo, DatabaseInfo,
462 AttributeSetInfo and AttributeDetails records at this stage. The
463 records may be transferred as GRS-1, SUTRS or Explain.
465 Fixed register spec so that colon isn't treated as size separator
466 unless followed by [0-9+-] in order to allow DOS drive specifications.
468 Fixed two bugs in ISAMC system.
470 Changed the way Zebra keeps its maintenance information about attribute
471 sets, available attributes, etc.. Records in "SGML" notation using an
472 EXPLAIN schema is now used when appropriate.
474 Bug fix: Index didn't handle update/insert/delete of the same record
475 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
476 first occurence of a record is considered.
478 Most searches now return correct number of hits.
480 New modular ranking system. Interested programmers are encouraged to
481 inspect rank1.c and improve the algorithm.
483 Bug fix: Lock files weren't removed as they should on NT.
485 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
486 specify a "sort register". Refer to the gils sample records which refer
487 to index type "s" which is specified as "sort" in the default.idx file.
488 Each sort criteria can either be Ascending or Descending and at most
489 three sort elements can be specified.
491 Bug fix: Character mapping didn't work for text files.
495 Simple ranked searches now return correct number of hits.
497 The test option (-s) only makes a read-lock on the index as well
498 as using read-only operations anywhere.
500 Moved towards generic character mapping. Configuration file default.idx
501 specifies character map files for register types w, p, u, etc.
503 Implemented "begin variant" for the sgml.regx - filter.
505 Fixed a few memory leaks.
507 Added support for C++, headers uses extern "C" for public definitions.
509 Bug fix: The show records facility (-s) only displayed information for
510 the first record in a file (and not for every record in the file).
512 Added option "-f <n>" to limit the logging of record operations. After
513 <n> records has been processed no logging is performed (unless errors
516 Bug fix: the compressed ISAM system didn't handle update operations
519 Added setting, "maxResultSetSize", to hold the number of records to
520 save in a result set.
522 Bug fix: Complete phrase did't work for search operations.
524 Bug fix: temporary result sets weren't deleted.
526 Reduced disk space for saved keys (storeKeys = 1).
528 Added optional, physical ANY (key replication)
530 Implemented proximity operator in search.
532 Bug fix: the path name buffers used by file match traversal routines
533 have been extended to support long file names.
535 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
536 configuration file. The resulting register without "storeKeys" is about
537 half the size, and the memory used by zebraidx during phase 2 (merge) is
538 reduced to a minimum.
540 Reworked the way Regexp-2 queries with error tolerance are handled and
541 specified. The documentation has been updated accordingly.
543 Bug fix: Zebrasrv didn't search correctly when queries contained masking
544 characters. This bug was introduced in 1.0a8.
546 Zebrasrv now tag records with the proper database name.
548 New settings, memMax and keyTmpDir.
550 Changed name of setting lockDir (previously called lockPath) and
551 setTmpDir (previously called tempSetPath).
553 Generalized and changed record type specifications. In short, there are:
555 grs.sgml structured, "SGML-like" syntax
556 grs.regx.<filter> structured, Regular expression filter
557 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
558 is the name of an abstract syntax file.
559 Bug fix: Result sets weren't sorted in operations involving boolean
560 operations with "ranked" operands.
564 Added national character-handling subsystem.
568 Small modifications to input filters and profiles.
570 Added support for SOIF syntax (with private OID).
574 Fixed buffer-size problem in indexing.
576 Added compression to temporary files for updating.
578 Added phrase registers.
580 Added dynamic mapping of search attribute to multiple termlists (ANY).
582 Scan support in multiple databases/registers.
584 Configuration settings are case-insensitive and single dash (-)
585 characters are ignored in comparisons.
587 The index processing ignores empty files - warning given.
589 New option to zebraidx (-V) displays version information.
593 Fixed problem in file-update system.
595 Fixed problem in shadow system; register was sometimes corrupted after
600 Fixed problems in the ISAM subsystem. Caused difficulties when updating
603 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
604 the rank and record number.
606 Fixed bug in the isam subsystem - caused a malfunction when accessing
607 words which occurred more than 10000 times.
609 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
612 Server can now run under inetd. Use option -i, and -w <directory> to
613 set working directory to desired location.
615 New zebraidx command: clean - removes temporary shadow files.
617 Fixed bug in ISAM system. Occurred rarely during register updates.
619 Logging during index merge phase is improved. The remaining running
622 Temporary files generated by zebraidx are removed after each run.
624 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
625 when doing scan operations in dictionaries with European characters.
629 A whole slew of updates, to make the first publicized release. Get the doc
634 Memory-problems in ISAM fixed. More blocktypes added to the default setup
635 to increase performance on larger databases.
637 Various minor changes in data management system.
641 A couple of portability-problems resolved.
643 Changed some malloc() to xmalloc().
