2 Update Perl internals so that it matches the current Zebra API.
3 The recordGroup structure is no longer available. A group of resources
4 can still be referenced by setting groupName=>.. in various methods.
6 Maximum number of records to be sorted in a result set can be
7 specified by setting "sortmax". Default is 1000.
9 Allow use of string use attributes for regular attribute sets. The
10 name matches the name given in the attribute set file. All strings
11 starting with / are considered X-Path as usual.
13 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
14 element for XML tree. It may only pop off if -record is given.
16 Added grs.danbib filter - for Danish Bibliographic Centre.
18 Rename CHANGELOG to NEWS.
22 For text filter, return only header if elementSetName=H . elementSetName=R
23 returns contents only. Other elementSetName returns both header+content.
25 Added test for charmap and rusmarc.
27 Added feature charmaps (.chr) so that characters may be specified in
30 Fixed problem with encoding directive for charmap(.chr) files.
32 Allow Remote insert/delete/replace/update with record, recordIdNumber
33 (sysno) and/or recordIdOpaque(user supplied record Id). If both
34 IDs are omitted internal record ID match is assumed (recordId: - in
39 Fix bug. X-Path attribute expressions with spaces in them now works.
41 Fix base address for MARC output.
45 Fix bug with shadow and result set handling.
47 Implement MARCXML to ISO2709 conversion.
51 Add missing examples for Windows install.
53 Fix bug in regx filter to make it "greedy" again. This bug appeared
60 Fix XML error handling. Stop XML parse immediately if XML parse error
61 occur (i.e. produce one error only).
63 Zebra ignores "unsupported use attribute" for individual databases
64 when search multiple databases (unless all databases fail).
66 New filter grs.marcxml which works like grs.marc but produces MARCXML.
68 Added support for database deletion. It is possible to create/drop
69 a database from zebraidx utility. Note: only for isam:b.
71 Write zebrasrv.pid to lockdir.
73 Bug fix: result sets were not recovered correctly. Had to
74 add ODR handle for zebra_search_RPN in order to make it work.
76 Fixed a bug in regx filters that didn't do anchors (^) correctly.
78 Fixed a bug in searches with X-Path searches sometimes giving "extra"
81 Zebra server checks for zebrasrv.pid and refuses to start if it is already
82 locked by another (running) zebrasrv.
84 Fixed a bug with text being chunked in pieces for the grs.xml filter.
88 xelm code updates. xelm works regardless state of 'xpath enable/disable'
89 Avoid -L/usr/lib since that is already default library path.
91 Allow multiple updates within one transaction.
93 Fixed a bug with >2GB files (overflow in integer expression).
97 Fix linker error for Perl module.
99 Fix bug in and operation which in some cases could result in "extra"
100 hits. Bug was introduced in 1.3.5.
102 Fix bug in handling of schema conversion when producing numeric tags.
108 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
112 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
113 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
114 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
116 livrank: another experimental ranking algorithm. Source in livcode.c.
117 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
119 Contributed by Pete Mallinson, University of Liverpool.
121 Advanced MARC indexing. See doc/marc_indexing.xml
122 Oleg Kolobov <oleg at lib.tpu.ru>
124 Perl API updates and fixes.
125 Peter Popovics <pop at technomat.hu>
127 Fixed 'zebraidx delete'.
129 Implemented 'zebraidx clean'.
131 64-bit offsets for register files on WIN32 (no 2 GB limit).
133 Fixed a few memory leaks WRT sorting.
137 Fixed error handling : error code was not properly returned.
139 Support Truncation 104 (CCL).
143 Added missing source files for perl extension.
147 Implemented xelm directive.
149 Updated for newer version of YAZ (introduction of string schema).
151 Directory examples/zthes now part of distribution (was missing
152 in previous release).
154 New .abs directive, systag, that control where to put retrieval
155 information. The directive takes two arguments: system tag, element name.
156 System tag is one of : rank, sysno, size.
160 Perl Filter and Perl API. By Peter Popovics.
162 For zebra.cfg, if no profilePath is specified, directory
163 (prefix)/share/idzebra/tab
166 Zebra Examples in examples . Zebra tests in test.
168 Bug fix: sort index was not properly modified on
169 record updates/deletes.
171 Fix handling of character entities for sgml filter.
173 Move data1 to Zebra (used to be part of YAZ).
177 Fix character encoding of scan response terms.
179 Fix character decoding of scan request terms.
181 Fix ESpec handling (requires YAZ 1.9.1)
183 Fix searches for complete fields.
187 When name zebra is used in a filename or directory 'idzebra' is used
188 instead to avoid confusion with GNU zebra (routing software).
190 Zebra server stops with a fatal error if config file cannot be read.
192 New config setting, followLinks, that controls whether update of files
193 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
194 By default symbolic links are followed.
196 Fix MARC transfer . MARC fields had wrong data for multiple fields.
198 XML record reader moved from YAZ to Zebra, to make YAZ less
199 dependant on external libraries.
201 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
202 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
203 on systems that doesn't offer iconv.
205 XML record reader supports external system entities.
209 New .abs-directive "xpath" that takes one argument: "enable"
210 or "disable" to enable and disable XPath -indexing. If no "xpath"
211 direcive is found in .abs-file , XPath-indexing is disabled to ensure
212 backwards compatibility. For missing .abs-files XPath-indexing is
213 enabled so that such records are searchable.
215 Zebra warns about missing .abs-file only once (for each type).
217 Fixed a bug in file update where already-inserted files could
222 Zebra license changed to GNU GPL.
224 XPath-like queries used when RPN string attributes are used, eg.
225 @attr 1=/portal/title sometitle
226 @attr 1=/portal/title[@xml:lang=da] danishtitle
227 @attr 1=/portal/title/@xml:lang da
228 @attr 1=//title sometitle
230 Zebra uses UTF-8 internally:
231 1) New setting "encoding" for zebra.cfg that specifies encoding for
232 OCTET terms in queries and record encoding for most transfer syntaxes
233 (except those that use International Strings, such as GRS-1).
234 2) The encoding of International strings is UTF-8 by default. It
235 may be changed by character set negotiation. If character set
236 negotiation is in effect and if records are selected for conversion
237 these'll be converted to the selected character set - thus overriding
238 the encoding setting in zebra.cfg.
239 3) New directive "encoding" in .abs-files. This specifies the external
240 character encoding for files indexed by zebra. However, if records
241 themselves have an XML header that specifies and encoding that'll be used
244 XML filter (-t grs.xml).
246 Multiple registers. New setting in resource 'root' that holds base
247 directory for register(s). A group a databases may be put in separate
248 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
252 Fixes for Digital Unix
254 Implemented hits per term using USR:SearchResult-1.
256 New Zebra API. Locking system re-implemented.
258 --- 1.1.stable 2002/02/20
260 Rank weight can be controlled with attribute type 9. Default
261 value is 34. Recommended values between 1-36.
265 Updated for YAZ version 1.8.
267 Added support for termsets - a result set of terms matching
268 a given query. For @attr 8=<set> creates termset named <set>.
270 Added support for raw retrieval. Element Set Name R forces the
271 text filter which returns the record in its original form.
273 Added numerical sort - triggered by structure=numeric (4=109).
275 Remote record import using Z39.50 Extended Services and Segments.
277 Fixed bug where updating a database with user-defined attributes
278 could corrupt the register (bad storeKeys).
280 Multi-threaded version.
282 Fixed bug regarding proximity.
284 Documentation updates.
286 Fixed bug in record retrieval module that occured on 64-bit OSF
291 Fixed bug in makefile for WIN32.
293 Fixed bug in configure script - used bash-specific features.
297 Added support for multiple records in one file for filter grs.sgml.
299 Changed record index structure. New layout is incompatible with
300 previous releases. Added setting "recordcompression" to control
301 compression of records. Possible values are "none" (no
302 compression) and bzip2 (compression using libbz2).
304 Added XML transfer syntax support for retrieval of structured records.
305 Schema in CompSpec is recognised in retrieval of structured records.
307 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
308 that fails, the filter reads the file <filt>.flt (regx style filter).
310 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
311 Zebra's configure script automatically attempts to locate Tcl. For
312 manual Tcl configuration use option --with-tclconfig=<path> to specify
313 where Tcl's library files are located.
315 Implemented "compression" of Dictionary and ISAM system. Dictionary
318 Added "tagsysno" directive to zebra.cfg to control under which tag the
319 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
322 Added "tagrank" as above.
324 Changed file naming scheme for register files from <name>.mf.<no> to
327 Implemented "position"-flag for register type (as defined in
328 default.idx). When set to zero no position (or seqence number) is
329 saved in register for each word occurrence, thus saving some register
332 Implemented database mapping. Using mapdb one can specify a database
333 to be mapped to one or more physical databases. Usage:
334 mapdb <fromdb> <todb> ..
336 Added SOIF-filter. Thanks to Peter Valkenburg.
338 For the regx-filter "end element -record" may trigger a mark-of-record
339 if outer level is reached.
341 Tag sets may be typed in the reference to it. From the .abs-file the
342 "tagset" directive takes a third optional integer type for the tag set
343 referenced. From a .tag-file the "include" directive takes a third
344 optional type as well. The old "type" directive in the tag set itself
345 is still recognized but acts as the default type for the tag set.
347 Zebra supports the specification of arbitrary attributes sets, schemas
348 and tag sets, because of the change in YAZ' OID management system.
350 Fixed bug in Sort that caused it NOT to use character mapping as it
353 Zebra now uses GNU configure to generate Makefile(s).
355 Added un-optimised support for left and left/right truncation attributes.
357 Added support for relational operators on text when using RPN queries.
359 Added support for sort specifications in RPN queries. Type 7 specifies
360 'sort' where value 1=ascending, value 2=descending. The use attribute
361 specifies the field criteria as usual. The term specifies priority
362 where 0=first, 1=second, ...
364 Changed the way use attributes are specified in the recordId
367 Maximum number of databases in one Zebra register increased.
369 New setting, databasePath, which specifies that first directory during
370 update traversal is the database name (instead of a fixed one).
372 New setting, explainDatabase, which specifies that databases are
375 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
377 Implemented EXPLAIN database maintenance. Zebra automatically
378 generate - and update CategoryList, TargetInfo, DatabaseInfo,
379 AttributeSetInfo and AttributeDetails records at this stage. The
380 records may be transferred as GRS-1, SUTRS or Explain.
382 Fixed register spec so that colon isn't treated as size separator
383 unless followed by [0-9+-] in order to allow DOS drive specifications.
385 Fixed two bugs in ISAMC system.
387 Changed the way Zebra keeps its maintenance information about attribute
388 sets, available attributes, etc.. Records in "SGML" notation using an
389 EXPLAIN schema is now used when appropriate.
391 Bug fix: Index didn't handle update/insert/delete of the same record
392 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
393 first occurence of a record is considered.
395 Most searches now return correct number of hits.
397 New modular ranking system. Interested programmers are encouraged to
398 inspect rank1.c and improve the algorithm.
400 Bug fix: Lock files weren't removed as they should on NT.
402 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
403 specify a "sort register". Refer to the gils sample records which refer
404 to index type "s" which is specified as "sort" in the default.idx file.
405 Each sort criteria can either be Ascending or Descending and at most
406 three sort elements can be specified.
408 Bug fix: Character mapping didn't work for text files.
412 Simple ranked searches now return correct number of hits.
414 The test option (-s) only makes a read-lock on the index as well
415 as using read-only operations anywhere.
417 Moved towards generic character mapping. Configuration file default.idx
418 specifies character map files for register types w, p, u, etc.
420 Implemented "begin variant" for the sgml.regx - filter.
422 Fixed a few memory leaks.
424 Added support for C++, headers uses extern "C" for public definitions.
426 Bug fix: The show records facility (-s) only displayed information for
427 the first record in a file (and not for every record in the file).
429 Added option "-f <n>" to limit the logging of record operations. After
430 <n> records has been processed no logging is performed (unless errors
433 Bug fix: the compressed ISAM system didn't handle update operations
436 Added setting, "maxResultSetSize", to hold the number of records to
437 save in a result set.
439 Bug fix: Complete phrase did't work for search operations.
441 Bug fix: temporary result sets weren't deleted.
443 Reduced disk space for saved keys (storeKeys = 1).
445 Added optional, physical ANY (key replication)
447 Implemented proximity operator in search.
449 Bug fix: the path name buffers used by file match traversal routines
450 have been extended to support long file names.
452 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
453 configuration file. The resulting register without "storeKeys" is about
454 half the size, and the memory used by zebraidx during phase 2 (merge) is
455 reduced to a minimum.
457 Reworked the way Regexp-2 queries with error tolerance are handled and
458 specified. The documentation has been updated accordingly.
460 Bug fix: Zebrasrv didn't search correctly when queries contained masking
461 characters. This bug was introduced in 1.0a8.
463 Zebrasrv now tag records with the proper database name.
465 New settings, memMax and keyTmpDir.
467 Changed name of setting lockDir (previously called lockPath) and
468 setTmpDir (previously called tempSetPath).
470 Generalized and changed record type specifications. In short, there are:
472 grs.sgml structured, "SGML-like" syntax
473 grs.regx.<filter> structured, Regular expression filter
474 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
475 is the name of an abstract syntax file.
476 Bug fix: Result sets weren't sorted in operations involving boolean
477 operations with "ranked" operands.
481 Added national character-handling subsystem.
485 Small modifications to input filters and profiles.
487 Added support for SOIF syntax (with private OID).
491 Fixed buffer-size problem in indexing.
493 Added compression to temporary files for updating.
495 Added phrase registers.
497 Added dynamic mapping of search attribute to multiple termlists (ANY).
499 Scan support in multiple databases/registers.
501 Configuration settings are case-insensitive and single dash (-)
502 characters are ignored in comparisons.
504 The index processing ignores empty files - warning given.
506 New option to zebraidx (-V) displays version information.
510 Fixed problem in file-update system.
512 Fixed problem in shadow system; register was sometimes corrupted after
517 Fixed problems in the ISAM subsystem. Caused difficulties when updating
520 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
521 the rank and record number.
523 Fixed bug in the isam subsystem - caused a malfunction when accessing
524 words which occurred more than 10000 times.
526 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
529 Server can now run under inetd. Use option -i, and -w <directory> to
530 set working directory to desired location.
532 New zebraidx command: clean - removes temporary shadow files.
534 Fixed bug in ISAM system. Occurred rarely during register updates.
536 Logging during index merge phase is improved. The remaining running
539 Temporary files generated by zebraidx are removed after each run.
541 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
542 when doing scan operations in dictionaries with European characters.
546 A whole slew of updates, to make the first publicized release. Get the doc
551 Memory-problems in ISAM fixed. More blocktypes added to the default setup
552 to increase performance on larger databases.
554 Various minor changes in data management system.
558 A couple of portability-problems resolved.
560 Changed some malloc() to xmalloc().
