3 Fixed bug #415: Strange truncation behavior.
5 Added 'melm' directive to absyn format to simplify config files
6 for MARC-style databases. See tab/marc21.abs for an example.
8 Added support for special slement set _sysno_ which returns a
9 record ID for a record packed as a SUTRS record.
13 Documented authentication facility in Zebra. Added zebra.cfg directive
14 'passwd.c' which specifies user accounts file with encrypted passwords. The
15 directive 'passwd' specifies user accounts file with clear-text passwords.
16 The previous version of Zebra used plain/clear text depending on
17 configuration automatically. That caused upgrade trouble. Bug #356.
21 Depend on YAZ 2.0.18 or later in configure.
23 Fixed crash that could occur if ES update transaction failed.
25 Configure enables the use of the crypt API - if available.
27 Fixed bug #304: Fuzzy search regExpr-2 did not use proper error distance
30 Fixed bug #305: Scan now handles negative preferred-position-in-response.
32 Implemented the 'equivalent' directive for .chr-files.
36 For configure, support threading again. It was removed by mistake
39 Fixed bug #262: spaces in control fields in MARC returned.
41 Fixed bug #259: Second indicator lost in MARC records
45 Fixed bug #253: Setting group.database not honored
47 Fixed bug #252: Sort does not work.
49 Fixed bug #248: hit counts in combinatoric (and) searches in specific ..
53 Fixed bug #245: Time for getting records changes a lot based on record
56 Fixed bug #235: weird x-path results.
58 Avoid crash in ISAMB when isamb_pp_open gets ISAMB_POS = 0. In
59 this case EOF (no entries) is signalled. It fixes problem with
60 terms being deleted. See bug #109.
62 Fixed bug #169: Phrase term counts does not work. The bug exists in
65 Added mechanism to ignore leading articles when doing full-field indexing,
66 based on the character map files. See the manual for further discussion.
70 Fixed bug in record management. Releasing blocks could result in
73 Fixed bug in isam:b. A tree split could result in a lost item.
77 Add IDZebra.i to dist so that Perl extension builds again.
81 Added facility to make attibutes in grs.regx and grs.tcl filter using the
82 data command with argument -attribute <name> . The content of data is
83 the value of the attribute. This command should be used inside a
84 begin element , end element section.
86 Update zebra.nsi to NSIS 2.
88 Added a new 'cut' directive to charmaps (.chr files) which specifies that
89 only characters after the cutting char should be indexed.
91 Update Perl internals so that it matches the current Zebra API.
92 The recordGroup structure is no longer available. A group of resources
93 can still be referenced by setting groupName=>.. in various methods.
95 Maximum number of records to be sorted in a result set can be
96 specified by setting "sortmax". Default is 1000.
98 Allow use of string use attributes for regular attribute sets. The
99 name matches the name given in the attribute set file. All strings
100 starting with / are considered X-Path as usual.
102 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
103 element for XML tree. It may only pop off if -record is given.
105 Added grs.danbib filter - for Danish Bibliographic Centre.
107 Rename CHANGELOG to NEWS.
109 For text filter, return only header if elementSetName=H . elementSetName=R
110 returns contents only. Other elementSetName returns both header+content.
112 Added test for charmap and rusmarc.
114 Added feature charmaps (.chr) so that characters may be specified in
117 Fixed problem with encoding directive for charmap(.chr) files.
119 Allow Remote insert/delete/replace/update with record, recordIdNumber
120 (sysno) and/or recordIdOpaque(user supplied record Id). If both
121 IDs are omitted internal record ID match is assumed (recordId: - in
124 --- 1.3.15 2004/01/15

128 Fix base address for MARC output.
130 --- 1.3.14 2003/11/29
132 Fix bug with shadow and result set handling.
134 Implement MARCXML to ISO2709 conversion.
136 --- 1.3.13 2003/09/26
138 Add missing examples for Windows install.
140 Fix bug in regx filter to make it "greedy" again. This bug appeared
145 --- 1.3.12 2003/09/08
147 Fix XML error handling. Stop XML parse immediately if XML parse error
148 occur (i.e. produce one error only).
150 Zebra ignores "unsupported use attribute" for individual databases
151 when search multiple databases (unless all databases fail).
153 New filter grs.marcxml which works like grs.marc but produces MARCXML.
155 Added support for database deletion. It is possible to create/drop
156 a database from zebraidx utility. Note: only for isam:b.
158 Write zebrasrv.pid to lockdir.
160 Bug fix: result sets were not recovered correctly. Had to
161 add ODR handle for zebra_search_RPN in order to make it work.
163 Fixed a bug in regx filters that didn't do anchors (^) correctly.
165 Fixed a bug in searches with X-Path searches sometimes giving "extra"
168 Zebra server checks for zebrasrv.pid and refuses to start if it is already
169 locked by another (running) zebrasrv.
171 Fixed a bug with text being chunked in pieces for the grs.xml filter.
173 --- 1.3.11 2003/04/25
175 xelm code updates. xelm works regardless state of 'xpath enable/disable'
176 Avoid -L/usr/lib since that is already default library path.
178 Allow multiple updates within one transaction.
180 Fixed a bug with >2GB files (overflow in integer expression).
182 --- 1.3.10 2003/04/01
184 Fix linker error for Perl module.
186 Fix bug in and operation which in some cases could result in "extra"
187 hits. Bug was introduced in 1.3.5.
189 Fix bug in handling of schema conversion when producing numeric tags.
195 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
199 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
200 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
201 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
203 livrank: another experimental ranking algorithm. Source in livcode.c.
204 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
206 Contributed by Pete Mallinson, University of Liverpool.
208 Advanced MARC indexing. See doc/marc_indexing.xml
209 Oleg Kolobov <oleg at lib.tpu.ru>
211 Perl API updates and fixes.
212 Peter Popovics <pop at technomat.hu>
214 Fixed 'zebraidx delete'.
216 Implemented 'zebraidx clean'.
218 64-bit offsets for register files on WIN32 (no 2 GB limit).
220 Fixed a few memory leaks WRT sorting.
224 Fixed error handling : error code was not properly returned.
226 Support Truncation 104 (CCL).
230 Added missing source files for perl extension.
234 Implemented xelm directive.
236 Updated for newer version of YAZ (introduction of string schema).
238 Directory examples/zthes now part of distribution (was missing
239 in previous release).
241 New .abs directive, systag, that control where to put retrieval
242 information. The directive takes two arguments: system tag, element name.
243 System tag is one of : rank, sysno, size.
247 Perl Filter and Perl API. By Peter Popovics.
249 For zebra.cfg, if no profilePath is specified, directory
250 (prefix)/share/idzebra/tab
253 Zebra Examples in examples . Zebra tests in test.
255 Bug fix: sort index was not properly modified on
256 record updates/deletes.
258 Fix handling of character entities for sgml filter.
260 Move data1 to Zebra (used to be part of YAZ).
264 Fix character encoding of scan response terms.
266 Fix character decoding of scan request terms.
268 Fix ESpec handling (requires YAZ 1.9.1)
270 Fix searches for complete fields.
274 When name zebra is used in a filename or directory 'idzebra' is used
275 instead to avoid confusion with GNU zebra (routing software).
277 Zebra server stops with a fatal error if config file cannot be read.
279 New config setting, followLinks, that controls whether update of files
280 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
281 By default symbolic links are followed.
283 Fix MARC transfer . MARC fields had wrong data for multiple fields.
285 XML record reader moved from YAZ to Zebra, to make YAZ less
286 dependant on external libraries.
288 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
289 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
290 on systems that doesn't offer iconv.
292 XML record reader supports external system entities.
296 New .abs-directive "xpath" that takes one argument: "enable"
297 or "disable" to enable and disable XPath -indexing. If no "xpath"
298 direcive is found in .abs-file , XPath-indexing is disabled to ensure
299 backwards compatibility. For missing .abs-files XPath-indexing is
300 enabled so that such records are searchable.
302 Zebra warns about missing .abs-file only once (for each type).
304 Fixed a bug in file update where already-inserted files could
309 Zebra license changed to GNU GPL.
311 XPath-like queries used when RPN string attributes are used, eg.
312 @attr 1=/portal/title sometitle
313 @attr 1=/portal/title[@xml:lang=da] danishtitle
314 @attr 1=/portal/title/@xml:lang da
315 @attr 1=//title sometitle
317 Zebra uses UTF-8 internally:
318 1) New setting "encoding" for zebra.cfg that specifies encoding for
319 OCTET terms in queries and record encoding for most transfer syntaxes
320 (except those that use International Strings, such as GRS-1).
321 2) The encoding of International strings is UTF-8 by default. It
322 may be changed by character set negotiation. If character set
323 negotiation is in effect and if records are selected for conversion
324 these'll be converted to the selected character set - thus overriding
325 the encoding setting in zebra.cfg.
326 3) New directive "encoding" in .abs-files. This specifies the external
327 character encoding for files indexed by zebra. However, if records
328 themselves have an XML header that specifies and encoding that'll be used
331 XML filter (-t grs.xml).
333 Multiple registers. New setting in resource 'root' that holds base
334 directory for register(s). A group a databases may be put in separate
335 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
339 Fixes for Digital Unix
341 Implemented hits per term using USR:SearchResult-1.
343 New Zebra API. Locking system re-implemented.
345 --- 1.1.stable 2002/02/20
347 Rank weight can be controlled with attribute type 9. Default
348 value is 34. Recommended values between 1-36.
352 Updated for YAZ version 1.8.
354 Added support for termsets - a result set of terms matching
355 a given query. For @attr 8=<set> creates termset named <set>.
357 Added support for raw retrieval. Element Set Name R forces the
358 text filter which returns the record in its original form.
360 Added numerical sort - triggered by structure=numeric (4=109).
362 Remote record import using Z39.50 Extended Services and Segments.
364 Fixed bug where updating a database with user-defined attributes
365 could corrupt the register (bad storeKeys).
367 Multi-threaded version.
369 Fixed bug regarding proximity.
371 Documentation updates.
373 Fixed bug in record retrieval module that occured on 64-bit OSF
378 Fixed bug in makefile for WIN32.
380 Fixed bug in configure script - used bash-specific features.
384 Added support for multiple records in one file for filter grs.sgml.
386 Changed record index structure. New layout is incompatible with
387 previous releases. Added setting "recordcompression" to control
388 compression of records. Possible values are "none" (no
389 compression) and bzip2 (compression using libbz2).
391 Added XML transfer syntax support for retrieval of structured records.
392 Schema in CompSpec is recognised in retrieval of structured records.
394 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
395 that fails, the filter reads the file <filt>.flt (regx style filter).
397 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
398 Zebra's configure script automatically attempts to locate Tcl. For
399 manual Tcl configuration use option --with-tclconfig=<path> to specify
400 where Tcl's library files are located.
402 Implemented "compression" of Dictionary and ISAM system. Dictionary
405 Added "tagsysno" directive to zebra.cfg to control under which tag the
406 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
409 Added "tagrank" as above.
411 Changed file naming scheme for register files from <name>.mf.<no> to
414 Implemented "position"-flag for register type (as defined in
415 default.idx). When set to zero no position (or seqence number) is
416 saved in register for each word occurrence, thus saving some register
419 Implemented database mapping. Using mapdb one can specify a database
420 to be mapped to one or more physical databases. Usage:
421 mapdb <fromdb> <todb> ..
423 Added SOIF-filter. Thanks to Peter Valkenburg.
425 For the regx-filter "end element -record" may trigger a mark-of-record
426 if outer level is reached.
428 Tag sets may be typed in the reference to it. From the .abs-file the
429 "tagset" directive takes a third optional integer type for the tag set
430 referenced. From a .tag-file the "include" directive takes a third
431 optional type as well. The old "type" directive in the tag set itself
432 is still recognized but acts as the default type for the tag set.
434 Zebra supports the specification of arbitrary attributes sets, schemas
435 and tag sets, because of the change in YAZ' OID management system.
437 Fixed bug in Sort that caused it NOT to use character mapping as it
440 Zebra now uses GNU configure to generate Makefile(s).
442 Added un-optimised support for left and left/right truncation attributes.
444 Added support for relational operators on text when using RPN queries.
446 Added support for sort specifications in RPN queries. Type 7 specifies
447 'sort' where value 1=ascending, value 2=descending. The use attribute
448 specifies the field criteria as usual. The term specifies priority
449 where 0=first, 1=second, ...
451 Changed the way use attributes are specified in the recordId
454 Maximum number of databases in one Zebra register increased.
456 New setting, databasePath, which specifies that first directory during
457 update traversal is the database name (instead of a fixed one).
459 New setting, explainDatabase, which specifies that databases are
462 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
464 Implemented EXPLAIN database maintenance. Zebra automatically
465 generate - and update CategoryList, TargetInfo, DatabaseInfo,
466 AttributeSetInfo and AttributeDetails records at this stage. The
467 records may be transferred as GRS-1, SUTRS or Explain.
469 Fixed register spec so that colon isn't treated as size separator
470 unless followed by [0-9+-] in order to allow DOS drive specifications.
472 Fixed two bugs in ISAMC system.
474 Changed the way Zebra keeps its maintenance information about attribute
475 sets, available attributes, etc.. Records in "SGML" notation using an
476 EXPLAIN schema is now used when appropriate.
478 Bug fix: Index didn't handle update/insert/delete of the same record
479 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
480 first occurence of a record is considered.
482 Most searches now return correct number of hits.
484 New modular ranking system. Interested programmers are encouraged to
485 inspect rank1.c and improve the algorithm.
487 Bug fix: Lock files weren't removed as they should on NT.
489 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
490 specify a "sort register". Refer to the gils sample records which refer
491 to index type "s" which is specified as "sort" in the default.idx file.
492 Each sort criteria can either be Ascending or Descending and at most
493 three sort elements can be specified.
495 Bug fix: Character mapping didn't work for text files.
499 Simple ranked searches now return correct number of hits.
501 The test option (-s) only makes a read-lock on the index as well
502 as using read-only operations anywhere.
504 Moved towards generic character mapping. Configuration file default.idx
505 specifies character map files for register types w, p, u, etc.
507 Implemented "begin variant" for the sgml.regx - filter.
509 Fixed a few memory leaks.
511 Added support for C++, headers uses extern "C" for public definitions.
513 Bug fix: The show records facility (-s) only displayed information for
514 the first record in a file (and not for every record in the file).
516 Added option "-f <n>" to limit the logging of record operations. After
517 <n> records has been processed no logging is performed (unless errors
520 Bug fix: the compressed ISAM system didn't handle update operations
523 Added setting, "maxResultSetSize", to hold the number of records to
524 save in a result set.
526 Bug fix: Complete phrase did't work for search operations.
528 Bug fix: temporary result sets weren't deleted.
530 Reduced disk space for saved keys (storeKeys = 1).
532 Added optional, physical ANY (key replication)
534 Implemented proximity operator in search.
536 Bug fix: the path name buffers used by file match traversal routines
537 have been extended to support long file names.
539 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
540 configuration file. The resulting register without "storeKeys" is about
541 half the size, and the memory used by zebraidx during phase 2 (merge) is
542 reduced to a minimum.
544 Reworked the way Regexp-2 queries with error tolerance are handled and
545 specified. The documentation has been updated accordingly.
547 Bug fix: Zebrasrv didn't search correctly when queries contained masking
548 characters. This bug was introduced in 1.0a8.
550 Zebrasrv now tag records with the proper database name.
552 New settings, memMax and keyTmpDir.
554 Changed name of setting lockDir (previously called lockPath) and
555 setTmpDir (previously called tempSetPath).
557 Generalized and changed record type specifications. In short, there are:
559 grs.sgml structured, "SGML-like" syntax
560 grs.regx.<filter> structured, Regular expression filter
561 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
562 is the name of an abstract syntax file.
563 Bug fix: Result sets weren't sorted in operations involving boolean
564 operations with "ranked" operands.
568 Added national character-handling subsystem.
572 Small modifications to input filters and profiles.
574 Added support for SOIF syntax (with private OID).
578 Fixed buffer-size problem in indexing.
580 Added compression to temporary files for updating.
582 Added phrase registers.
584 Added dynamic mapping of search attribute to multiple termlists (ANY).
586 Scan support in multiple databases/registers.
588 Configuration settings are case-insensitive and single dash (-)
589 characters are ignored in comparisons.
591 The index processing ignores empty files - warning given.
593 New option to zebraidx (-V) displays version information.
597 Fixed problem in file-update system.
599 Fixed problem in shadow system; register was sometimes corrupted after
604 Fixed problems in the ISAM subsystem. Caused difficulties when updating
607 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
608 the rank and record number.
610 Fixed bug in the isam subsystem - caused a malfunction when accessing
611 words which occurred more than 10000 times.
613 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
616 Server can now run under inetd. Use option -i, and -w <directory> to
617 set working directory to desired location.
619 New zebraidx command: clean - removes temporary shadow files.
621 Fixed bug in ISAM system. Occurred rarely during register updates.
623 Logging during index merge phase is improved. The remaining running
626 Temporary files generated by zebraidx are removed after each run.
628 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
629 when doing scan operations in dictionaries with European characters.
633 A whole slew of updates, to make the first publicized release. Get the doc
638 Memory-problems in ISAM fixed. More blocktypes added to the default setup
639 to increase performance on larger databases.
641 Various minor changes in data management system.
645 A couple of portability-problems resolved.
647 Changed some malloc() to xmalloc().
