2 Remove isamd. It's not been in use for a long time and isamb is better
5 Change SYSNO to be zint. Change pointers in isamc and isamb to zint.
6 Change block number in bfile/cfile to zint. zint is a long integer
7 (64-bit). This change practially removes register limits for Zebra.
9 Implement int-list encoding for ISAMs.
11 Added facility to make attibutes in grs.regx and grs.tcl filter using the
12 data command with argument -attribute <name> . The content of data is
13 the value of the attribute. This command should be used inside a
14 begin element , end element section.
16 Update zebra.nsi to NSIS 2.
18 Added a new 'cut' directive to charmaps (.chr files) which specifies that
19 only characters after the cutting char should be indexed.
21 Update Perl internals so that it matches the current Zebra API.
22 The recordGroup structure is no longer available. A group of resources
23 can still be referenced by setting groupName=>.. in various methods.
25 Maximum number of records to be sorted in a result set can be
26 specified by setting "sortmax". Default is 1000.
28 Allow use of string use attributes for regular attribute sets. The
29 name matches the name given in the attribute set file. All strings
30 starting with / are considered X-Path as usual.
32 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
33 element for XML tree. It may only pop off if -record is given.
35 Added grs.danbib filter - for Danish Bibliographic Centre.
37 Rename CHANGELOG to NEWS.
39 For text filter, return only header if elementSetName=H . elementSetName=R
40 returns contents only. Other elementSetName returns both header+content.
42 Added test for charmap and rusmarc.
44 Added feature charmaps (.chr) so that characters may be specified in
47 Fixed problem with encoding directive for charmap(.chr) files.
49 Allow Remote insert/delete/replace/update with record, recordIdNumber
50 (sysno) and/or recordIdOpaque(user supplied record Id). If both
51 IDs are omitted internal record ID match is assumed (recordId: - in
56 Fix bug. X-Path attribute expressions with spaces in them now works.
58 Fix base address for MARC output.
62 Fix bug with shadow and result set handling.
64 Implement MARCXML to ISO2709 conversion.
68 Add missing examples for Windows install.
70 Fix bug in regx filter to make it "greedy" again. This bug appeared
77 Fix XML error handling. Stop XML parse immediately if XML parse error
78 occur (i.e. produce one error only).
80 Zebra ignores "unsupported use attribute" for individual databases
81 when search multiple databases (unless all databases fail).
83 New filter grs.marcxml which works like grs.marc but produces MARCXML.
85 Added support for database deletion. It is possible to create/drop
86 a database from zebraidx utility. Note: only for isam:b.
88 Write zebrasrv.pid to lockdir.
90 Bug fix: result sets were not recovered correctly. Had to
91 add ODR handle for zebra_search_RPN in order to make it work.
93 Fixed a bug in regx filters that didn't do anchors (^) correctly.
95 Fixed a bug in searches with X-Path searches sometimes giving "extra"
98 Zebra server checks for zebrasrv.pid and refuses to start if it is already
99 locked by another (running) zebrasrv.
101 Fixed a bug with text being chunked in pieces for the grs.xml filter.
103 --- 1.3.11 2003/04/25
105 xelm code updates. xelm works regardless state of 'xpath enable/disable'
106 Avoid -L/usr/lib since that is already default library path.
108 Allow multiple updates within one transaction.
110 Fixed a bug with >2GB files (overflow in integer expression).
112 --- 1.3.10 2003/04/01
114 Fix linker error for Perl module.
116 Fix bug in and operation which in some cases could result in "extra"
117 hits. Bug was introduced in 1.3.5.
119 Fix bug in handling of schema conversion when producing numeric tags.
125 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
129 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
130 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
131 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
133 livrank: another experimental ranking algorithm. Source in livcode.c.
134 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
136 Contributed by Pete Mallinson, University of Liverpool.
138 Advanced MARC indexing. See doc/marc_indexing.xml
139 Oleg Kolobov <oleg at lib.tpu.ru>
141 Perl API updates and fixes.
142 Peter Popovics <pop at technomat.hu>
144 Fixed 'zebraidx delete'.
146 Implemented 'zebraidx clean'.
148 64-bit offsets for register files on WIN32 (no 2 GB limit).
150 Fixed a few memory leaks WRT sorting.
154 Fixed error handling : error code was not properly returned.
156 Support Truncation 104 (CCL).
160 Added missing source files for perl extension.
164 Implemented xelm directive.
166 Updated for newer version of YAZ (introduction of string schema).
168 Directory examples/zthes now part of distribution (was missing
169 in previous release).
171 New .abs directive, systag, that control where to put retrieval
172 information. The directive takes two arguments: system tag, element name.
173 System tag is one of : rank, sysno, size.
177 Perl Filter and Perl API. By Peter Popovics.
179 For zebra.cfg, if no profilePath is specified, directory
180 (prefix)/share/idzebra/tab
183 Zebra Examples in examples . Zebra tests in test.
185 Bug fix: sort index was not properly modified on
186 record updates/deletes.
188 Fix handling of character entities for sgml filter.
190 Move data1 to Zebra (used to be part of YAZ).
194 Fix character encoding of scan response terms.
196 Fix character decoding of scan request terms.
198 Fix ESpec handling (requires YAZ 1.9.1)
200 Fix searches for complete fields.
204 When name zebra is used in a filename or directory 'idzebra' is used
205 instead to avoid confusion with GNU zebra (routing software).
207 Zebra server stops with a fatal error if config file cannot be read.
209 New config setting, followLinks, that controls whether update of files
210 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
211 By default symbolic links are followed.
213 Fix MARC transfer . MARC fields had wrong data for multiple fields.
215 XML record reader moved from YAZ to Zebra, to make YAZ less
216 dependant on external libraries.
218 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
219 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
220 on systems that doesn't offer iconv.
222 XML record reader supports external system entities.
226 New .abs-directive "xpath" that takes one argument: "enable"
227 or "disable" to enable and disable XPath -indexing. If no "xpath"
228 direcive is found in .abs-file , XPath-indexing is disabled to ensure
229 backwards compatibility. For missing .abs-files XPath-indexing is
230 enabled so that such records are searchable.
232 Zebra warns about missing .abs-file only once (for each type).
234 Fixed a bug in file update where already-inserted files could
239 Zebra license changed to GNU GPL.
241 XPath-like queries used when RPN string attributes are used, eg.
242 @attr 1=/portal/title sometitle
243 @attr 1=/portal/title[@xml:lang=da] danishtitle
244 @attr 1=/portal/title/@xml:lang da
245 @attr 1=//title sometitle
247 Zebra uses UTF-8 internally:
248 1) New setting "encoding" for zebra.cfg that specifies encoding for
249 OCTET terms in queries and record encoding for most transfer syntaxes
250 (except those that use International Strings, such as GRS-1).
251 2) The encoding of International strings is UTF-8 by default. It
252 may be changed by character set negotiation. If character set
253 negotiation is in effect and if records are selected for conversion
254 these'll be converted to the selected character set - thus overriding
255 the encoding setting in zebra.cfg.
256 3) New directive "encoding" in .abs-files. This specifies the external
257 character encoding for files indexed by zebra. However, if records
258 themselves have an XML header that specifies and encoding that'll be used
261 XML filter (-t grs.xml).
263 Multiple registers. New setting in resource 'root' that holds base
264 directory for register(s). A group a databases may be put in separate
265 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
269 Fixes for Digital Unix
271 Implemented hits per term using USR:SearchResult-1.
273 New Zebra API. Locking system re-implemented.
275 --- 1.1.stable 2002/02/20
277 Rank weight can be controlled with attribute type 9. Default
278 value is 34. Recommended values between 1-36.
282 Updated for YAZ version 1.8.
284 Added support for termsets - a result set of terms matching
285 a given query. For @attr 8=<set> creates termset named <set>.
287 Added support for raw retrieval. Element Set Name R forces the
288 text filter which returns the record in its original form.
290 Added numerical sort - triggered by structure=numeric (4=109).
292 Remote record import using Z39.50 Extended Services and Segments.
294 Fixed bug where updating a database with user-defined attributes
295 could corrupt the register (bad storeKeys).
297 Multi-threaded version.
299 Fixed bug regarding proximity.
301 Documentation updates.
303 Fixed bug in record retrieval module that occured on 64-bit OSF
308 Fixed bug in makefile for WIN32.
310 Fixed bug in configure script - used bash-specific features.
314 Added support for multiple records in one file for filter grs.sgml.
316 Changed record index structure. New layout is incompatible with
317 previous releases. Added setting "recordcompression" to control
318 compression of records. Possible values are "none" (no
319 compression) and bzip2 (compression using libbz2).
321 Added XML transfer syntax support for retrieval of structured records.
322 Schema in CompSpec is recognised in retrieval of structured records.
324 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
325 that fails, the filter reads the file <filt>.flt (regx style filter).
327 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
328 Zebra's configure script automatically attempts to locate Tcl. For
329 manual Tcl configuration use option --with-tclconfig=<path> to specify
330 where Tcl's library files are located.
332 Implemented "compression" of Dictionary and ISAM system. Dictionary
335 Added "tagsysno" directive to zebra.cfg to control under which tag the
336 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
339 Added "tagrank" as above.
341 Changed file naming scheme for register files from <name>.mf.<no> to
344 Implemented "position"-flag for register type (as defined in
345 default.idx). When set to zero no position (or seqence number) is
346 saved in register for each word occurrence, thus saving some register
349 Implemented database mapping. Using mapdb one can specify a database
350 to be mapped to one or more physical databases. Usage:
351 mapdb <fromdb> <todb> ..
353 Added SOIF-filter. Thanks to Peter Valkenburg.
355 For the regx-filter "end element -record" may trigger a mark-of-record
356 if outer level is reached.
358 Tag sets may be typed in the reference to it. From the .abs-file the
359 "tagset" directive takes a third optional integer type for the tag set
360 referenced. From a .tag-file the "include" directive takes a third
361 optional type as well. The old "type" directive in the tag set itself
362 is still recognized but acts as the default type for the tag set.
364 Zebra supports the specification of arbitrary attributes sets, schemas
365 and tag sets, because of the change in YAZ' OID management system.
367 Fixed bug in Sort that caused it NOT to use character mapping as it
370 Zebra now uses GNU configure to generate Makefile(s).
372 Added un-optimised support for left and left/right truncation attributes.
374 Added support for relational operators on text when using RPN queries.
376 Added support for sort specifications in RPN queries. Type 7 specifies
377 'sort' where value 1=ascending, value 2=descending. The use attribute
378 specifies the field criteria as usual. The term specifies priority
379 where 0=first, 1=second, ...
381 Changed the way use attributes are specified in the recordId
384 Maximum number of databases in one Zebra register increased.
386 New setting, databasePath, which specifies that first directory during
387 update traversal is the database name (instead of a fixed one).
389 New setting, explainDatabase, which specifies that databases are
392 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
394 Implemented EXPLAIN database maintenance. Zebra automatically
395 generate - and update CategoryList, TargetInfo, DatabaseInfo,
396 AttributeSetInfo and AttributeDetails records at this stage. The
397 records may be transferred as GRS-1, SUTRS or Explain.
399 Fixed register spec so that colon isn't treated as size separator
400 unless followed by [0-9+-] in order to allow DOS drive specifications.
402 Fixed two bugs in ISAMC system.
404 Changed the way Zebra keeps its maintenance information about attribute
405 sets, available attributes, etc.. Records in "SGML" notation using an
406 EXPLAIN schema is now used when appropriate.
408 Bug fix: Index didn't handle update/insert/delete of the same record
409 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
410 first occurence of a record is considered.
412 Most searches now return correct number of hits.
414 New modular ranking system. Interested programmers are encouraged to
415 inspect rank1.c and improve the algorithm.
417 Bug fix: Lock files weren't removed as they should on NT.
419 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
420 specify a "sort register". Refer to the gils sample records which refer
421 to index type "s" which is specified as "sort" in the default.idx file.
422 Each sort criteria can either be Ascending or Descending and at most
423 three sort elements can be specified.
425 Bug fix: Character mapping didn't work for text files.
429 Simple ranked searches now return correct number of hits.
431 The test option (-s) only makes a read-lock on the index as well
432 as using read-only operations anywhere.
434 Moved towards generic character mapping. Configuration file default.idx
435 specifies character map files for register types w, p, u, etc.
437 Implemented "begin variant" for the sgml.regx - filter.
439 Fixed a few memory leaks.
441 Added support for C++, headers uses extern "C" for public definitions.
443 Bug fix: The show records facility (-s) only displayed information for
444 the first record in a file (and not for every record in the file).
446 Added option "-f <n>" to limit the logging of record operations. After
447 <n> records has been processed no logging is performed (unless errors
450 Bug fix: the compressed ISAM system didn't handle update operations
453 Added setting, "maxResultSetSize", to hold the number of records to
454 save in a result set.
456 Bug fix: Complete phrase did't work for search operations.
458 Bug fix: temporary result sets weren't deleted.
460 Reduced disk space for saved keys (storeKeys = 1).
462 Added optional, physical ANY (key replication)
464 Implemented proximity operator in search.
466 Bug fix: the path name buffers used by file match traversal routines
467 have been extended to support long file names.
469 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
470 configuration file. The resulting register without "storeKeys" is about
471 half the size, and the memory used by zebraidx during phase 2 (merge) is
472 reduced to a minimum.
474 Reworked the way Regexp-2 queries with error tolerance are handled and
475 specified. The documentation has been updated accordingly.
477 Bug fix: Zebrasrv didn't search correctly when queries contained masking
478 characters. This bug was introduced in 1.0a8.
480 Zebrasrv now tag records with the proper database name.
482 New settings, memMax and keyTmpDir.
484 Changed name of setting lockDir (previously called lockPath) and
485 setTmpDir (previously called tempSetPath).
487 Generalized and changed record type specifications. In short, there are:
489 grs.sgml structured, "SGML-like" syntax
490 grs.regx.<filter> structured, Regular expression filter
491 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
492 is the name of an abstract syntax file.
493 Bug fix: Result sets weren't sorted in operations involving boolean
494 operations with "ranked" operands.
498 Added national character-handling subsystem.
502 Small modifications to input filters and profiles.
504 Added support for SOIF syntax (with private OID).
508 Fixed buffer-size problem in indexing.
510 Added compression to temporary files for updating.
512 Added phrase registers.
514 Added dynamic mapping of search attribute to multiple termlists (ANY).
516 Scan support in multiple databases/registers.
518 Configuration settings are case-insensitive and single dash (-)
519 characters are ignored in comparisons.
521 The index processing ignores empty files - warning given.
523 New option to zebraidx (-V) displays version information.
527 Fixed problem in file-update system.
529 Fixed problem in shadow system; register was sometimes corrupted after
534 Fixed problems in the ISAM subsystem. Caused difficulties when updating
537 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
538 the rank and record number.
540 Fixed bug in the isam subsystem - caused a malfunction when accessing
541 words which occurred more than 10000 times.
543 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
546 Server can now run under inetd. Use option -i, and -w <directory> to
547 set working directory to desired location.
549 New zebraidx command: clean - removes temporary shadow files.
551 Fixed bug in ISAM system. Occurred rarely during register updates.
553 Logging during index merge phase is improved. The remaining running
556 Temporary files generated by zebraidx are removed after each run.
558 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
559 when doing scan operations in dictionaries with European characters.
563 A whole slew of updates, to make the first publicized release. Get the doc
568 Memory-problems in ISAM fixed. More blocktypes added to the default setup
569 to increase performance on larger databases.
571 Various minor changes in data management system.
575 A couple of portability-problems resolved.
577 Changed some malloc() to xmalloc().
