2 New filter grs.marcxml which works like grs.marc but produces MARCXML.
4 Write zebrasrv.pid to lockdir.
6 Bug fix: result sets were not recovered correctly. Had to
7 add ODR handle for zebra_search_RPN in order to make it work.
9 Fixed a bug in regx filters that didn't do anchors (^) correctly.
11 Fixed a bug in searches with X-Path searches sometimes giving "extra"
14 Zebra server checks for zebrasrv.pid and refuses to start if it is already
15 locked by another (running) zebrasrv.
17 Fixed a bug with text being chunked in pieces for the grs.xml filter.
21 xelm code updates. xelm works regardless state of 'xpath enable/disable'
22 Avoid -L/usr/lib since that is already default library path.
24 Allow multiple updates within one transaction.
26 Fixed a bug with >2GB files (overflow in integer expression).
30 Fix linker error for Perl module.
32 Fix bug in and operation which in some cases could result in "extra"
33 hits. Bug was introduced in 1.3.5.
35 Fix bug in handling of schema conversion when producing numeric tags.
41 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
45 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
46 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
47 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
49 livrank: another experimental ranking algorithm. Source in livcode.c.
50 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
52 Contributed by Pete Mallinson, University of Liverpool.
54 Advanced MARC indexing. See doc/marc_indexing.xml
55 Oleg Kolobov <oleg at lib.tpu.ru>
57 Perl API updates and fixes.
58 Peter Popovics <pop at technomat.hu>
60 Fixed 'zebraidx delete'.
62 Implemented 'zebraidx clean'.
64 64-bit offsets for register files on WIN32 (no 2 GB limit).
66 Fixed a few memory leaks WRT sorting.
70 Fixed error handling : error code was not properly returned.
72 Support Truncation 104 (CCL).
76 Added missing source files for perl extension.
80 Implemented xelm directive.
82 Updated for newer version of YAZ (introduction of string schema).
84 Directory examples/zthes now part of distribution (was missing
87 New .abs directive, systag, that control where to put retrieval
88 information. The directive takes two arguments: system tag, element name.
89 System tag is one of : rank, sysno, size.
93 Perl Filter and Perl API. By Peter Popovics.
95 For zebra.cfg, if no profilePath is specified, directory
96 (prefix)/share/idzebra/tab
99 Zebra Examples in examples . Zebra tests in test.
101 Bug fix: sort index was not properly modified on
102 record updates/deletes.
104 Fix handling of character entities for sgml filter.
106 Move data1 to Zebra (used to be part of YAZ).
110 Fix character encoding of scan response terms.
112 Fix character decoding of scan request terms.
114 Fix ESpec handling (requires YAZ 1.9.1)
116 Fix searches for complete fields.
120 When name zebra is used in a filename or directory 'idzebra' is used
121 instead to avoid confusion with GNU zebra (routing software).
123 Zebra server stops with a fatal error if config file cannot be read.
125 New config setting, followLinks, that controls whether update of files
126 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
127 By default symbolic links are followed.
129 Fix MARC transfer . MARC fields had wrong data for multiple fields.
131 XML record reader moved from YAZ to Zebra, to make YAZ less
132 dependant on external libraries.
134 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
135 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
136 on systems that doesn't offer iconv.
138 XML record reader supports external system entities.
142 New .abs-directive "xpath" that takes one argument: "enable"
143 or "disable" to enable and disable XPath -indexing. If no "xpath"
144 direcive is found in .abs-file , XPath-indexing is disabled to ensure
145 backwards compatibility. For missing .abs-files XPath-indexing is
146 enabled so that such records are searchable.
148 Zebra warns about missing .abs-file only once (for each type).
150 Fixed a bug in file update where already-inserted files could
155 Zebra license changed to GNU GPL.
157 XPath-like queries used when RPN string attributes are used, eg.
158 @attr 1=/portal/title sometitle
159 @attr 1=/portal/title[@xml:lang=da] danishtitle
160 @attr 1=/portal/title/@xml:lang da
161 @attr 1=//title sometitle
163 Zebra uses UTF-8 internally:
164 1) New setting "encoding" for zebra.cfg that specifies encoding for
165 OCTET terms in queries and record encoding for most transfer syntaxes
166 (except those that use International Strings, such as GRS-1).
167 2) The encoding of International strings is UTF-8 by default. It
168 may be changed by character set negotiation. If character set
169 negotiation is in effect and if records are selected for conversion
170 these'll be converted to the selected character set - thus overriding
171 the encoding setting in zebra.cfg.
172 3) New directive "encoding" in .abs-files. This specifies the external
173 character encoding for files indexed by zebra. However, if records
174 themselves have an XML header that specifies and encoding that'll be used
177 XML filter (-t grs.xml).
179 Multiple registers. New setting in resource 'root' that holds base
180 directory for register(s). A group a databases may be put in separate
181 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
185 Fixes for Digital Unix
187 Implemented hits per term using USR:SearchResult-1.
189 New Zebra API. Locking system re-implemented.
191 --- 1.1.stable 2002/02/20
193 Rank weight can be controlled with attribute type 9. Default
194 value is 34. Recommended values between 1-36.
198 Updated for YAZ version 1.8.
200 Added support for termsets - a result set of terms matching
201 a given query. For @attr 8=<set> creates termset named <set>.
203 Added support for raw retrieval. Element Set Name R forces the
204 text filter which returns the record in its original form.
206 Added numerical sort - triggered by structure=numeric (4=109).
208 Remote record import using Z39.50 Extended Services and Segments.
210 Fixed bug where updating a database with user-defined attributes
211 could corrupt the register (bad storeKeys).
213 Multi-threaded version.
215 Fixed bug regarding proximity.
217 Documentation updates.
219 Fixed bug in record retrieval module that occured on 64-bit OSF
224 Fixed bug in makefile for WIN32.
226 Fixed bug in configure script - used bash-specific features.
230 Added support for multiple records in one file for filter grs.sgml.
232 Changed record index structure. New layout is incompatible with
233 previous releases. Added setting "recordcompression" to control
234 compression of records. Possible values are "none" (no
235 compression) and bzip2 (compression using libbz2).
237 Added XML transfer syntax support for retrieval of structured records.
238 Schema in CompSpec is recognised in retrieval of structured records.
240 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
241 that fails, the filter reads the file <filt>.flt (regx style filter).
243 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
244 Zebra's configure script automatically attempts to locate Tcl. For
245 manual Tcl configuration use option --with-tclconfig=<path> to specify
246 where Tcl's library files are located.
248 Implemented "compression" of Dictionary and ISAM system. Dictionary
251 Added "tagsysno" directive to zebra.cfg to control under which tag the
252 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
255 Added "tagrank" as above.
257 Changed file naming scheme for register files from <name>.mf.<no> to
260 Implemented "position"-flag for register type (as defined in
261 default.idx). When set to zero no position (or seqence number) is
262 saved in register for each word occurrence, thus saving some register
265 Implemented database mapping. Using mapdb one can specify a database
266 to be mapped to one or more physical databases. Usage:
267 mapdb <fromdb> <todb> ..
269 Added SOIF-filter. Thanks to Peter Valkenburg.
271 For the regx-filter "end element -record" may trigger a mark-of-record
272 if outer level is reached.
274 Tag sets may be typed in the reference to it. From the .abs-file the
275 "tagset" directive takes a third optional integer type for the tag set
276 referenced. From a .tag-file the "include" directive takes a third
277 optional type as well. The old "type" directive in the tag set itself
278 is still recognized but acts as the default type for the tag set.
280 Zebra supports the specification of arbitrary attributes sets, schemas
281 and tag sets, because of the change in YAZ' OID management system.
283 Fixed bug in Sort that caused it NOT to use character mapping as it
286 Zebra now uses GNU configure to generate Makefile(s).
288 Added un-optimised support for left and left/right truncation attributes.
290 Added support for relational operators on text when using RPN queries.
292 Added support for sort specifications in RPN queries. Type 7 specifies
293 'sort' where value 1=ascending, value 2=descending. The use attribute
294 specifies the field criteria as usual. The term specifies priority
295 where 0=first, 1=second, ...
297 Changed the way use attributes are specified in the recordId
300 Maximum number of databases in one Zebra register increased.
302 New setting, databasePath, which specifies that first directory during
303 update traversal is the database name (instead of a fixed one).
305 New setting, explainDatabase, which specifies that databases are
308 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
310 Implemented EXPLAIN database maintenance. Zebra automatically
311 generate - and update CategoryList, TargetInfo, DatabaseInfo,
312 AttributeSetInfo and AttributeDetails records at this stage. The
313 records may be transferred as GRS-1, SUTRS or Explain.
315 Fixed register spec so that colon isn't treated as size separator
316 unless followed by [0-9+-] in order to allow DOS drive specifications.
318 Fixed two bugs in ISAMC system.
320 Changed the way Zebra keeps its maintenance information about attribute
321 sets, available attributes, etc.. Records in "SGML" notation using an
322 EXPLAIN schema is now used when appropriate.
324 Bug fix: Index didn't handle update/insert/delete of the same record
325 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
326 first occurence of a record is considered.
328 Most searches now return correct number of hits.
330 New modular ranking system. Interested programmers are encouraged to
331 inspect rank1.c and improve the algorithm.
333 Bug fix: Lock files weren't removed as they should on NT.
335 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
336 specify a "sort register". Refer to the gils sample records which refer
337 to index type "s" which is specified as "sort" in the default.idx file.
338 Each sort criteria can either be Ascending or Descending and at most
339 three sort elements can be specified.
341 Bug fix: Character mapping didn't work for text files.
345 Simple ranked searches now return correct number of hits.
347 The test option (-s) only makes a read-lock on the index as well
348 as using read-only operations anywhere.
350 Moved towards generic character mapping. Configuration file default.idx
351 specifies character map files for register types w, p, u, etc.
353 Implemented "begin variant" for the sgml.regx - filter.
355 Fixed a few memory leaks.
357 Added support for C++, headers uses extern "C" for public definitions.
359 Bug fix: The show records facility (-s) only displayed information for
360 the first record in a file (and not for every record in the file).
362 Added option "-f <n>" to limit the logging of record operations. After
363 <n> records has been processed no logging is performed (unless errors
366 Bug fix: the compressed ISAM system didn't handle update operations
369 Added setting, "maxResultSetSize", to hold the number of records to
370 save in a result set.
372 Bug fix: Complete phrase did't work for search operations.
374 Bug fix: temporary result sets weren't deleted.
376 Reduced disk space for saved keys (storeKeys = 1).
378 Added optional, physical ANY (key replication)
380 Implemented proximity operator in search.
382 Bug fix: the path name buffers used by file match traversal routines
383 have been extended to support long file names.
385 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
386 configuration file. The resulting register without "storeKeys" is about
387 half the size, and the memory used by zebraidx during phase 2 (merge) is
388 reduced to a minimum.
390 Reworked the way Regexp-2 queries with error tolerance are handled and
391 specified. The documentation has been updated accordingly.
393 Bug fix: Zebrasrv didn't search correctly when queries contained masking
394 characters. This bug was introduced in 1.0a8.
396 Zebrasrv now tag records with the proper database name.
398 New settings, memMax and keyTmpDir.
400 Changed name of setting lockDir (previously called lockPath) and
401 setTmpDir (previously called tempSetPath).
403 Generalized and changed record type specifications. In short, there are:
405 grs.sgml structured, "SGML-like" syntax
406 grs.regx.<filter> structured, Regular expression filter
407 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
408 is the name of an abstract syntax file.
409 Bug fix: Result sets weren't sorted in operations involving boolean
410 operations with "ranked" operands.
414 Added national character-handling subsystem.
418 Small modifications to input filters and profiles.
420 Added support for SOIF syntax (with private OID).
424 Fixed buffer-size problem in indexing.
426 Added compression to temporary files for updating.
428 Added phrase registers.
430 Added dynamic mapping of search attribute to multiple termlists (ANY).
432 Scan support in multiple databases/registers.
434 Configuration settings are case-insensitive and single dash (-)
435 characters are ignored in comparisons.
437 The index processing ignores empty files - warning given.
439 New option to zebraidx (-V) displays version information.
443 Fixed problem in file-update system.
445 Fixed problem in shadow system; register was sometimes corrupted after
450 Fixed problems in the ISAM subsystem. Caused difficulties when updating
453 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
454 the rank and record number.
456 Fixed bug in the isam subsystem - caused a malfunction when accessing
457 words which occurred more than 10000 times.
459 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
462 Server can now run under inetd. Use option -i, and -w <directory> to
463 set working directory to desired location.
465 New zebraidx command: clean - removes temporary shadow files.
467 Fixed bug in ISAM system. Occurred rarely during register updates.
469 Logging during index merge phase is improved. The remaining running
472 Temporary files generated by zebraidx are removed after each run.
474 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
475 when doing scan operations in dictionaries with European characters.
479 A whole slew of updates, to make the first publicized release. Get the doc
484 Memory-problems in ISAM fixed. More blocktypes added to the default setup
485 to increase performance on larger databases.
487 Various minor changes in data management system.
491 A couple of portability-problems resolved.
493 Changed some malloc() to xmalloc().
