2 Update zebra.nsi to NSIS 2.
4 Added a new 'cut' directive to charmaps (.chr files) which specifies that
5 only characters after the cutting char should be indexed.
7 Update Perl internals so that it matches the current Zebra API.
8 The recordGroup structure is no longer available. A group of resources
9 can still be referenced by setting groupName=>.. in various methods.
11 Maximum number of records to be sorted in a result set can be
12 specified by setting "sortmax". Default is 1000.
14 Allow use of string use attributes for regular attribute sets. The
15 name matches the name given in the attribute set file. All strings
16 starting with / are considered X-Path as usual.
18 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
19 element for XML tree. It may only pop off if -record is given.
21 Added grs.danbib filter - for Danish Bibliographic Centre.
23 Rename CHANGELOG to NEWS.
25 For text filter, return only header if elementSetName=H . elementSetName=R
26 returns contents only. Other elementSetName returns both header+content.
28 Added test for charmap and rusmarc.
30 Added feature charmaps (.chr) so that characters may be specified in
33 Fixed problem with encoding directive for charmap(.chr) files.
35 Allow Remote insert/delete/replace/update with record, recordIdNumber
36 (sysno) and/or recordIdOpaque(user supplied record Id). If both
37 IDs are omitted internal record ID match is assumed (recordId: - in
42 Fix bug. X-Path attribute expressions with spaces in them now works.
44 Fix base address for MARC output.
48 Fix bug with shadow and result set handling.
50 Implement MARCXML to ISO2709 conversion.
54 Add missing examples for Windows install.
56 Fix bug in regx filter to make it "greedy" again. This bug appeared
63 Fix XML error handling. Stop XML parse immediately if XML parse error
64 occur (i.e. produce one error only).
66 Zebra ignores "unsupported use attribute" for individual databases
67 when search multiple databases (unless all databases fail).
69 New filter grs.marcxml which works like grs.marc but produces MARCXML.
71 Added support for database deletion. It is possible to create/drop
72 a database from zebraidx utility. Note: only for isam:b.
74 Write zebrasrv.pid to lockdir.
76 Bug fix: result sets were not recovered correctly. Had to
77 add ODR handle for zebra_search_RPN in order to make it work.
79 Fixed a bug in regx filters that didn't do anchors (^) correctly.
81 Fixed a bug in searches with X-Path searches sometimes giving "extra"
84 Zebra server checks for zebrasrv.pid and refuses to start if it is already
85 locked by another (running) zebrasrv.
87 Fixed a bug with text being chunked in pieces for the grs.xml filter.
91 xelm code updates. xelm works regardless state of 'xpath enable/disable'
92 Avoid -L/usr/lib since that is already default library path.
94 Allow multiple updates within one transaction.
96 Fixed a bug with >2GB files (overflow in integer expression).
100 Fix linker error for Perl module.
102 Fix bug in and operation which in some cases could result in "extra"
103 hits. Bug was introduced in 1.3.5.
105 Fix bug in handling of schema conversion when producing numeric tags.
111 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
115 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
116 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
117 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
119 livrank: another experimental ranking algorithm. Source in livcode.c.
120 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
122 Contributed by Pete Mallinson, University of Liverpool.
124 Advanced MARC indexing. See doc/marc_indexing.xml
125 Oleg Kolobov <oleg at lib.tpu.ru>
127 Perl API updates and fixes.
128 Peter Popovics <pop at technomat.hu>
130 Fixed 'zebraidx delete'.
132 Implemented 'zebraidx clean'.
134 64-bit offsets for register files on WIN32 (no 2 GB limit).
136 Fixed a few memory leaks WRT sorting.
140 Fixed error handling : error code was not properly returned.
142 Support Truncation 104 (CCL).
146 Added missing source files for perl extension.
150 Implemented xelm directive.
152 Updated for newer version of YAZ (introduction of string schema).
154 Directory examples/zthes now part of distribution (was missing
155 in previous release).
157 New .abs directive, systag, that control where to put retrieval
158 information. The directive takes two arguments: system tag, element name.
159 System tag is one of : rank, sysno, size.
163 Perl Filter and Perl API. By Peter Popovics.
165 For zebra.cfg, if no profilePath is specified, directory
166 (prefix)/share/idzebra/tab
169 Zebra Examples in examples . Zebra tests in test.
171 Bug fix: sort index was not properly modified on
172 record updates/deletes.
174 Fix handling of character entities for sgml filter.
176 Move data1 to Zebra (used to be part of YAZ).
180 Fix character encoding of scan response terms.
182 Fix character decoding of scan request terms.
184 Fix ESpec handling (requires YAZ 1.9.1)
186 Fix searches for complete fields.
190 When name zebra is used in a filename or directory 'idzebra' is used
191 instead to avoid confusion with GNU zebra (routing software).
193 Zebra server stops with a fatal error if config file cannot be read.
195 New config setting, followLinks, that controls whether update of files
196 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
197 By default symbolic links are followed.
199 Fix MARC transfer . MARC fields had wrong data for multiple fields.
201 XML record reader moved from YAZ to Zebra, to make YAZ less
202 dependant on external libraries.
204 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
205 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
206 on systems that doesn't offer iconv.
208 XML record reader supports external system entities.
212 New .abs-directive "xpath" that takes one argument: "enable"
213 or "disable" to enable and disable XPath -indexing. If no "xpath"
214 direcive is found in .abs-file , XPath-indexing is disabled to ensure
215 backwards compatibility. For missing .abs-files XPath-indexing is
216 enabled so that such records are searchable.
218 Zebra warns about missing .abs-file only once (for each type).
220 Fixed a bug in file update where already-inserted files could
225 Zebra license changed to GNU GPL.
227 XPath-like queries used when RPN string attributes are used, eg.
228 @attr 1=/portal/title sometitle
229 @attr 1=/portal/title[@xml:lang=da] danishtitle
230 @attr 1=/portal/title/@xml:lang da
231 @attr 1=//title sometitle
233 Zebra uses UTF-8 internally:
234 1) New setting "encoding" for zebra.cfg that specifies encoding for
235 OCTET terms in queries and record encoding for most transfer syntaxes
236 (except those that use International Strings, such as GRS-1).
237 2) The encoding of International strings is UTF-8 by default. It
238 may be changed by character set negotiation. If character set
239 negotiation is in effect and if records are selected for conversion
240 these'll be converted to the selected character set - thus overriding
241 the encoding setting in zebra.cfg.
242 3) New directive "encoding" in .abs-files. This specifies the external
243 character encoding for files indexed by zebra. However, if records
244 themselves have an XML header that specifies and encoding that'll be used
247 XML filter (-t grs.xml).
249 Multiple registers. New setting in resource 'root' that holds base
250 directory for register(s). A group a databases may be put in separate
251 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
255 Fixes for Digital Unix
257 Implemented hits per term using USR:SearchResult-1.
259 New Zebra API. Locking system re-implemented.
261 --- 1.1.stable 2002/02/20
263 Rank weight can be controlled with attribute type 9. Default
264 value is 34. Recommended values between 1-36.
268 Updated for YAZ version 1.8.
270 Added support for termsets - a result set of terms matching
271 a given query. For @attr 8=<set> creates termset named <set>.
273 Added support for raw retrieval. Element Set Name R forces the
274 text filter which returns the record in its original form.
276 Added numerical sort - triggered by structure=numeric (4=109).
278 Remote record import using Z39.50 Extended Services and Segments.
280 Fixed bug where updating a database with user-defined attributes
281 could corrupt the register (bad storeKeys).
283 Multi-threaded version.
285 Fixed bug regarding proximity.
287 Documentation updates.
289 Fixed bug in record retrieval module that occured on 64-bit OSF
294 Fixed bug in makefile for WIN32.
296 Fixed bug in configure script - used bash-specific features.
300 Added support for multiple records in one file for filter grs.sgml.
302 Changed record index structure. New layout is incompatible with
303 previous releases. Added setting "recordcompression" to control
304 compression of records. Possible values are "none" (no
305 compression) and bzip2 (compression using libbz2).
307 Added XML transfer syntax support for retrieval of structured records.
308 Schema in CompSpec is recognised in retrieval of structured records.
310 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
311 that fails, the filter reads the file <filt>.flt (regx style filter).
313 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
314 Zebra's configure script automatically attempts to locate Tcl. For
315 manual Tcl configuration use option --with-tclconfig=<path> to specify
316 where Tcl's library files are located.
318 Implemented "compression" of Dictionary and ISAM system. Dictionary
321 Added "tagsysno" directive to zebra.cfg to control under which tag the
322 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
325 Added "tagrank" as above.
327 Changed file naming scheme for register files from <name>.mf.<no> to
330 Implemented "position"-flag for register type (as defined in
331 default.idx). When set to zero no position (or seqence number) is
332 saved in register for each word occurrence, thus saving some register
335 Implemented database mapping. Using mapdb one can specify a database
336 to be mapped to one or more physical databases. Usage:
337 mapdb <fromdb> <todb> ..
339 Added SOIF-filter. Thanks to Peter Valkenburg.
341 For the regx-filter "end element -record" may trigger a mark-of-record
342 if outer level is reached.
344 Tag sets may be typed in the reference to it. From the .abs-file the
345 "tagset" directive takes a third optional integer type for the tag set
346 referenced. From a .tag-file the "include" directive takes a third
347 optional type as well. The old "type" directive in the tag set itself
348 is still recognized but acts as the default type for the tag set.
350 Zebra supports the specification of arbitrary attributes sets, schemas
351 and tag sets, because of the change in YAZ' OID management system.
353 Fixed bug in Sort that caused it NOT to use character mapping as it
356 Zebra now uses GNU configure to generate Makefile(s).
358 Added un-optimised support for left and left/right truncation attributes.
360 Added support for relational operators on text when using RPN queries.
362 Added support for sort specifications in RPN queries. Type 7 specifies
363 'sort' where value 1=ascending, value 2=descending. The use attribute
364 specifies the field criteria as usual. The term specifies priority
365 where 0=first, 1=second, ...
367 Changed the way use attributes are specified in the recordId
370 Maximum number of databases in one Zebra register increased.
372 New setting, databasePath, which specifies that first directory during
373 update traversal is the database name (instead of a fixed one).
375 New setting, explainDatabase, which specifies that databases are
378 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
380 Implemented EXPLAIN database maintenance. Zebra automatically
381 generate - and update CategoryList, TargetInfo, DatabaseInfo,
382 AttributeSetInfo and AttributeDetails records at this stage. The
383 records may be transferred as GRS-1, SUTRS or Explain.
385 Fixed register spec so that colon isn't treated as size separator
386 unless followed by [0-9+-] in order to allow DOS drive specifications.
388 Fixed two bugs in ISAMC system.
390 Changed the way Zebra keeps its maintenance information about attribute
391 sets, available attributes, etc.. Records in "SGML" notation using an
392 EXPLAIN schema is now used when appropriate.
394 Bug fix: Index didn't handle update/insert/delete of the same record
395 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
396 first occurence of a record is considered.
398 Most searches now return correct number of hits.
400 New modular ranking system. Interested programmers are encouraged to
401 inspect rank1.c and improve the algorithm.
403 Bug fix: Lock files weren't removed as they should on NT.
405 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
406 specify a "sort register". Refer to the gils sample records which refer
407 to index type "s" which is specified as "sort" in the default.idx file.
408 Each sort criteria can either be Ascending or Descending and at most
409 three sort elements can be specified.
411 Bug fix: Character mapping didn't work for text files.
415 Simple ranked searches now return correct number of hits.
417 The test option (-s) only makes a read-lock on the index as well
418 as using read-only operations anywhere.
420 Moved towards generic character mapping. Configuration file default.idx
421 specifies character map files for register types w, p, u, etc.
423 Implemented "begin variant" for the sgml.regx - filter.
425 Fixed a few memory leaks.
427 Added support for C++, headers uses extern "C" for public definitions.
429 Bug fix: The show records facility (-s) only displayed information for
430 the first record in a file (and not for every record in the file).
432 Added option "-f <n>" to limit the logging of record operations. After
433 <n> records has been processed no logging is performed (unless errors
436 Bug fix: the compressed ISAM system didn't handle update operations
439 Added setting, "maxResultSetSize", to hold the number of records to
440 save in a result set.
442 Bug fix: Complete phrase did't work for search operations.
444 Bug fix: temporary result sets weren't deleted.
446 Reduced disk space for saved keys (storeKeys = 1).
448 Added optional, physical ANY (key replication)
450 Implemented proximity operator in search.
452 Bug fix: the path name buffers used by file match traversal routines
453 have been extended to support long file names.
455 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
456 configuration file. The resulting register without "storeKeys" is about
457 half the size, and the memory used by zebraidx during phase 2 (merge) is
458 reduced to a minimum.
460 Reworked the way Regexp-2 queries with error tolerance are handled and
461 specified. The documentation has been updated accordingly.
463 Bug fix: Zebrasrv didn't search correctly when queries contained masking
464 characters. This bug was introduced in 1.0a8.
466 Zebrasrv now tag records with the proper database name.
468 New settings, memMax and keyTmpDir.
470 Changed name of setting lockDir (previously called lockPath) and
471 setTmpDir (previously called tempSetPath).
473 Generalized and changed record type specifications. In short, there are:
475 grs.sgml structured, "SGML-like" syntax
476 grs.regx.<filter> structured, Regular expression filter
477 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
478 is the name of an abstract syntax file.
479 Bug fix: Result sets weren't sorted in operations involving boolean
480 operations with "ranked" operands.
484 Added national character-handling subsystem.
488 Small modifications to input filters and profiles.
490 Added support for SOIF syntax (with private OID).
494 Fixed buffer-size problem in indexing.
496 Added compression to temporary files for updating.
498 Added phrase registers.
500 Added dynamic mapping of search attribute to multiple termlists (ANY).
502 Scan support in multiple databases/registers.
504 Configuration settings are case-insensitive and single dash (-)
505 characters are ignored in comparisons.
507 The index processing ignores empty files - warning given.
509 New option to zebraidx (-V) displays version information.
513 Fixed problem in file-update system.
515 Fixed problem in shadow system; register was sometimes corrupted after
520 Fixed problems in the ISAM subsystem. Caused difficulties when updating
523 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
524 the rank and record number.
526 Fixed bug in the isam subsystem - caused a malfunction when accessing
527 words which occurred more than 10000 times.
529 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
532 Server can now run under inetd. Use option -i, and -w <directory> to
533 set working directory to desired location.
535 New zebraidx command: clean - removes temporary shadow files.
537 Fixed bug in ISAM system. Occurred rarely during register updates.
539 Logging during index merge phase is improved. The remaining running
542 Temporary files generated by zebraidx are removed after each run.
544 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
545 when doing scan operations in dictionaries with European characters.
549 A whole slew of updates, to make the first publicized release. Get the doc
554 Memory-problems in ISAM fixed. More blocktypes added to the default setup
555 to increase performance on larger databases.
557 Various minor changes in data management system.
561 A couple of portability-problems resolved.
563 Changed some malloc() to xmalloc().
