2 Support Truncation 104 (CCL).
6 Added missing source files for perl extension.
10 Implemented xelm directive.
12 Updated for newer version of YAZ (introduction of string schema).
14 Directory examples/zthes now part of distribution (was missing
17 New .abs directive, systag, that control where to put retrieval
18 information. The directive takes two arguments: system tag, element name.
19 System tag is one of : rank, sysno, size.
23 Perl Filter and Perl API. By Peter Popovics.
25 For zebra.cfg, if no profilePath is specified, directory
26 (prefix)/share/idzebra/tab
29 Zebra Examples in examples . Zebra tests in test.
31 Bug fix: sort index was not properly modified on
32 record updates/deletes.
34 Fix handling of character entities for sgml filter.
36 Move data1 to Zebra (used to be part of YAZ).
40 Fix character encoding of scan response terms.
42 Fix character decoding of scan request terms.
44 Fix ESpec handling (requires YAZ 1.9.1)
46 Fix searches for complete fields.
50 When name zebra is used in a filename or directory 'idzebra' is used
51 instead to avoid confusion with GNU zebra (routing software).
53 Zebra server stops with a fatal error if config file cannot be read.
55 New config setting, followLinks, that controls whether update of files
56 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
57 By default symbolic links are followed.
59 Fix MARC transfer . MARC fields had wrong data for multiple fields.
61 XML record reader moved from YAZ to Zebra, to make YAZ less
62 dependant on external libraries.
64 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
65 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
66 on systems that doesn't offer iconv.
68 XML record reader supports external system entities.
72 New .abs-directive "xpath" that takes one argument: "enable"
73 or "disable" to enable and disable XPath -indexing. If no "xpath"
74 direcive is found in .abs-file , XPath-indexing is disabled to ensure
75 backwards compatibility. For missing .abs-files XPath-indexing is
76 enabled so that such records are searchable.
78 Zebra warns about missing .abs-file only once (for each type).
80 Fixed a bug in file update where already-inserted files could
85 Zebra license changed to GNU GPL.
87 XPath-like queries used when RPN string attributes are used, eg.
88 @attr 1=/portal/title sometitle
89 @attr 1=/portal/title[@xml:lang=da] danishtitle
90 @attr 1=/portal/title/@xml:lang da
91 @attr 1=//title sometitle
93 Zebra uses UTF-8 internally:
94 1) New setting "encoding" for zebra.cfg that specifies encoding for
95 OCTET terms in queries and record encoding for most transfer syntaxes
96 (except those that use International Strings, such as GRS-1).
97 2) The encoding of International strings is UTF-8 by default. It
98 may be changed by character set negotiation. If character set
99 negotiation is in effect and if records are selected for conversion
100 these'll be converted to the selected character set - thus overriding
101 the encoding setting in zebra.cfg.
102 3) New directive "encoding" in .abs-files. This specifies the external
103 character encoding for files indexed by zebra. However, if records
104 themselves have an XML header that specifies and encoding that'll be used
107 XML filter (-t grs.xml).
109 Multiple registers. New setting in resource 'root' that holds base
110 directory for register(s). A group a databases may be put in separate
111 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
115 Fixes for Digital Unix
117 Implemented hits per term using USR:SearchResult-1.
119 New Zebra API. Locking system re-implemented.
121 --- 1.1.stable 2002/02/20
123 Rank weight can be controlled with attribute type 9. Default
124 value is 34. Recommended values between 1-36.
128 Updated for YAZ version 1.8.
130 Added support for termsets - a result set of terms matching
131 a given query. For @attr 8=<set> creates termset named <set>.
133 Added support for raw retrieval. Element Set Name R forces the
134 text filter which returns the record in its original form.
136 Added numerical sort - triggered by structure=numeric (4=109).
138 Remote record import using Z39.50 Extended Services and Segments.
140 Fixed bug where updating a database with user-defined attributes
141 could corrupt the register (bad storeKeys).
143 Multi-threaded version.
145 Fixed bug regarding proximity.
147 Documentation updates.
149 Fixed bug in record retrieval module that occured on 64-bit OSF
154 Fixed bug in makefile for WIN32.
156 Fixed bug in configure script - used bash-specific features.
160 Added support for multiple records in one file for filter grs.sgml.
162 Changed record index structure. New layout is incompatible with
163 previous releases. Added setting "recordcompression" to control
164 compression of records. Possible values are "none" (no
165 compression) and bzip2 (compression using libbz2).
167 Added XML transfer syntax support for retrieval of structured records.
168 Schema in CompSpec is recognised in retrieval of structured records.
170 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
171 that fails, the filter reads the file <filt>.flt (regx style filter).
173 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
174 Zebra's configure script automatically attempts to locate Tcl. For
175 manual Tcl configuration use option --with-tclconfig=<path> to specify
176 where Tcl's library files are located.
178 Implemented "compression" of Dictionary and ISAM system. Dictionary
181 Added "tagsysno" directive to zebra.cfg to control under which tag the
182 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
185 Added "tagrank" as above.
187 Changed file naming scheme for register files from <name>.mf.<no> to
190 Implemented "position"-flag for register type (as defined in
191 default.idx). When set to zero no position (or seqence number) is
192 saved in register for each word occurrence, thus saving some register
195 Implemented database mapping. Using mapdb one can specify a database
196 to be mapped to one or more physical databases. Usage:
197 mapdb <fromdb> <todb> ..
199 Added SOIF-filter. Thanks to Peter Valkenburg.
201 For the regx-filter "end element -record" may trigger a mark-of-record
202 if outer level is reached.
204 Tag sets may be typed in the reference to it. From the .abs-file the
205 "tagset" directive takes a third optional integer type for the tag set
206 referenced. From a .tag-file the "include" directive takes a third
207 optional type as well. The old "type" directive in the tag set itself
208 is still recognized but acts as the default type for the tag set.
210 Zebra supports the specification of arbitrary attributes sets, schemas
211 and tag sets, because of the change in YAZ' OID management system.
213 Fixed bug in Sort that caused it NOT to use character mapping as it
216 Zebra now uses GNU configure to generate Makefile(s).
218 Added un-optimised support for left and left/right truncation attributes.
220 Added support for relational operators on text when using RPN queries.
222 Added support for sort specifications in RPN queries. Type 7 specifies
223 'sort' where value 1=ascending, value 2=descending. The use attribute
224 specifies the field criteria as usual. The term specifies priority
225 where 0=first, 1=second, ...
227 Changed the way use attributes are specified in the recordId
230 Maximum number of databases in one Zebra register increased.
232 New setting, databasePath, which specifies that first directory during
233 update traversal is the database name (instead of a fixed one).
235 New setting, explainDatabase, which specifies that databases are
238 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
240 Implemented EXPLAIN database maintenance. Zebra automatically
241 generate - and update CategoryList, TargetInfo, DatabaseInfo,
242 AttributeSetInfo and AttributeDetails records at this stage. The
243 records may be transferred as GRS-1, SUTRS or Explain.
245 Fixed register spec so that colon isn't treated as size separator
246 unless followed by [0-9+-] in order to allow DOS drive specifications.
248 Fixed two bugs in ISAMC system.
250 Changed the way Zebra keeps its maintenance information about attribute
251 sets, available attributes, etc.. Records in "SGML" notation using an
252 EXPLAIN schema is now used when appropriate.
254 Bug fix: Index didn't handle update/insert/delete of the same record
255 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
256 first occurence of a record is considered.
258 Most searches now return correct number of hits.
260 New modular ranking system. Interested programmers are encouraged to
261 inspect rank1.c and improve the algorithm.
263 Bug fix: Lock files weren't removed as they should on NT.
265 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
266 specify a "sort register". Refer to the gils sample records which refer
267 to index type "s" which is specified as "sort" in the default.idx file.
268 Each sort criteria can either be Ascending or Descending and at most
269 three sort elements can be specified.
271 Bug fix: Character mapping didn't work for text files.
275 Simple ranked searches now return correct number of hits.
277 The test option (-s) only makes a read-lock on the index as well
278 as using read-only operations anywhere.
280 Moved towards generic character mapping. Configuration file default.idx
281 specifies character map files for register types w, p, u, etc.
283 Implemented "begin variant" for the sgml.regx - filter.
285 Fixed a few memory leaks.
287 Added support for C++, headers uses extern "C" for public definitions.
289 Bug fix: The show records facility (-s) only displayed information for
290 the first record in a file (and not for every record in the file).
292 Added option "-f <n>" to limit the logging of record operations. After
293 <n> records has been processed no logging is performed (unless errors
296 Bug fix: the compressed ISAM system didn't handle update operations
299 Added setting, "maxResultSetSize", to hold the number of records to
300 save in a result set.
302 Bug fix: Complete phrase did't work for search operations.
304 Bug fix: temporary result sets weren't deleted.
306 Reduced disk space for saved keys (storeKeys = 1).
308 Added optional, physical ANY (key replication)
310 Implemented proximity operator in search.
312 Bug fix: the path name buffers used by file match traversal routines
313 have been extended to support long file names.
315 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
316 configuration file. The resulting register without "storeKeys" is about
317 half the size, and the memory used by zebraidx during phase 2 (merge) is
318 reduced to a minimum.
320 Reworked the way Regexp-2 queries with error tolerance are handled and
321 specified. The documentation has been updated accordingly.
323 Bug fix: Zebrasrv didn't search correctly when queries contained masking
324 characters. This bug was introduced in 1.0a8.
326 Zebrasrv now tag records with the proper database name.
328 New settings, memMax and keyTmpDir.
330 Changed name of setting lockDir (previously called lockPath) and
331 setTmpDir (previously called tempSetPath).
333 Generalized and changed record type specifications. In short, there are:
335 grs.sgml structured, "SGML-like" syntax
336 grs.regx.<filter> structured, Regular expression filter
337 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
338 is the name of an abstract syntax file.
339 Bug fix: Result sets weren't sorted in operations involving boolean
340 operations with "ranked" operands.
344 Added national character-handling subsystem.
348 Small modifications to input filters and profiles.
350 Added support for SOIF syntax (with private OID).
354 Fixed buffer-size problem in indexing.
356 Added compression to temporary files for updating.
358 Added phrase registers.
360 Added dynamic mapping of search attribute to multiple termlists (ANY).
362 Scan support in multiple databases/registers.
364 Configuration settings are case-insensitive and single dash (-)
365 characters are ignored in comparisons.
367 The index processing ignores empty files - warning given.
369 New option to zebraidx (-V) displays version information.
373 Fixed problem in file-update system.
375 Fixed problem in shadow system; register was sometimes corrupted after
380 Fixed problems in the ISAM subsystem. Caused difficulties when updating
383 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
384 the rank and record number.
386 Fixed bug in the isam subsystem - caused a malfunction when accessing
387 words which occurred more than 10000 times.
389 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
392 Server can now run under inetd. Use option -i, and -w <directory> to
393 set working directory to desired location.
395 New zebraidx command: clean - removes temporary shadow files.
397 Fixed bug in ISAM system. Occurred rarely during register updates.
399 Logging during index merge phase is improved. The remaining running
402 Temporary files generated by zebraidx are removed after each run.
404 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
405 when doing scan operations in dictionaries with European characters.
409 A whole slew of updates, to make the first publicized release. Get the doc
414 Memory-problems in ISAM fixed. More blocktypes added to the default setup
415 to increase performance on larger databases.
417 Various minor changes in data management system.
421 A couple of portability-problems resolved.
423 Changed some malloc() to xmalloc().
