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 a new 'cut' directive to charmaps (.chr files) which specifies that
12 only characters after the cutting char should be indexed.
14 Update Perl internals so that it matches the current Zebra API.
15 The recordGroup structure is no longer available. A group of resources
16 can still be referenced by setting groupName=>.. in various methods.
18 Maximum number of records to be sorted in a result set can be
19 specified by setting "sortmax". Default is 1000.
21 Allow use of string use attributes for regular attribute sets. The
22 name matches the name given in the attribute set file. All strings
23 starting with / are considered X-Path as usual.
25 Fixed bug in grs.regx. filter . 'end element' could pop off top tag
26 element for XML tree. It may only pop off if -record is given.
28 Added grs.danbib filter - for Danish Bibliographic Centre.
30 Rename CHANGELOG to NEWS.
34 For text filter, return only header if elementSetName=H . elementSetName=R
35 returns contents only. Other elementSetName returns both header+content.
37 Added test for charmap and rusmarc.
39 Added feature charmaps (.chr) so that characters may be specified in
42 Fixed problem with encoding directive for charmap(.chr) files.
44 Allow Remote insert/delete/replace/update with record, recordIdNumber
45 (sysno) and/or recordIdOpaque(user supplied record Id). If both
46 IDs are omitted internal record ID match is assumed (recordId: - in
51 Fix bug. X-Path attribute expressions with spaces in them now works.
53 Fix base address for MARC output.
57 Fix bug with shadow and result set handling.
59 Implement MARCXML to ISO2709 conversion.
63 Add missing examples for Windows install.
65 Fix bug in regx filter to make it "greedy" again. This bug appeared
72 Fix XML error handling. Stop XML parse immediately if XML parse error
73 occur (i.e. produce one error only).
75 Zebra ignores "unsupported use attribute" for individual databases
76 when search multiple databases (unless all databases fail).
78 New filter grs.marcxml which works like grs.marc but produces MARCXML.
80 Added support for database deletion. It is possible to create/drop
81 a database from zebraidx utility. Note: only for isam:b.
83 Write zebrasrv.pid to lockdir.
85 Bug fix: result sets were not recovered correctly. Had to
86 add ODR handle for zebra_search_RPN in order to make it work.
88 Fixed a bug in regx filters that didn't do anchors (^) correctly.
90 Fixed a bug in searches with X-Path searches sometimes giving "extra"
93 Zebra server checks for zebrasrv.pid and refuses to start if it is already
94 locked by another (running) zebrasrv.
96 Fixed a bug with text being chunked in pieces for the grs.xml filter.
100 xelm code updates. xelm works regardless state of 'xpath enable/disable'
101 Avoid -L/usr/lib since that is already default library path.
103 Allow multiple updates within one transaction.
105 Fixed a bug with >2GB files (overflow in integer expression).
107 --- 1.3.10 2003/04/01
109 Fix linker error for Perl module.
111 Fix bug in and operation which in some cases could result in "extra"
112 hits. Bug was introduced in 1.3.5.
114 Fix bug in handling of schema conversion when producing numeric tags.
120 Add missing files doc/zvrank.txt and doc/marc_indexing.xml.
124 Zvrank: an experimental ranking algorithm. See doc/zvrank.txt and
125 source in index/zvrank.c. Enable this by using rank: zvrank in zebra.cfg.
126 Contributed by Johannes Leveling <Johannes.Leveling at fernuni-hagen.de>
128 livrank: another experimental ranking algorithm. Source in livcode.c.
129 Enable this by using rank: livrank in zebra.cfg and use -DLIV_CODE=1
131 Contributed by Pete Mallinson, University of Liverpool.
133 Advanced MARC indexing. See doc/marc_indexing.xml
134 Oleg Kolobov <oleg at lib.tpu.ru>
136 Perl API updates and fixes.
137 Peter Popovics <pop at technomat.hu>
139 Fixed 'zebraidx delete'.
141 Implemented 'zebraidx clean'.
143 64-bit offsets for register files on WIN32 (no 2 GB limit).
145 Fixed a few memory leaks WRT sorting.
149 Fixed error handling : error code was not properly returned.
151 Support Truncation 104 (CCL).
155 Added missing source files for perl extension.
159 Implemented xelm directive.
161 Updated for newer version of YAZ (introduction of string schema).
163 Directory examples/zthes now part of distribution (was missing
164 in previous release).
166 New .abs directive, systag, that control where to put retrieval
167 information. The directive takes two arguments: system tag, element name.
168 System tag is one of : rank, sysno, size.
172 Perl Filter and Perl API. By Peter Popovics.
174 For zebra.cfg, if no profilePath is specified, directory
175 (prefix)/share/idzebra/tab
178 Zebra Examples in examples . Zebra tests in test.
180 Bug fix: sort index was not properly modified on
181 record updates/deletes.
183 Fix handling of character entities for sgml filter.
185 Move data1 to Zebra (used to be part of YAZ).
189 Fix character encoding of scan response terms.
191 Fix character decoding of scan request terms.
193 Fix ESpec handling (requires YAZ 1.9.1)
195 Fix searches for complete fields.
199 When name zebra is used in a filename or directory 'idzebra' is used
200 instead to avoid confusion with GNU zebra (routing software).
202 Zebra server stops with a fatal error if config file cannot be read.
204 New config setting, followLinks, that controls whether update of files
205 should follow symbolic. Set it to 1 (for enable) or 0 (to disable).
206 By default symbolic links are followed.
208 Fix MARC transfer . MARC fields had wrong data for multiple fields.
210 XML record reader moved from YAZ to Zebra, to make YAZ less
211 dependant on external libraries.
213 Zebra uses yaz_iconv which is mini iconv library supporting UTF-8,
214 UCS4, ISO-8859-1. This means that Zebra does UNICODE even
215 on systems that doesn't offer iconv.
217 XML record reader supports external system entities.
221 New .abs-directive "xpath" that takes one argument: "enable"
222 or "disable" to enable and disable XPath -indexing. If no "xpath"
223 direcive is found in .abs-file , XPath-indexing is disabled to ensure
224 backwards compatibility. For missing .abs-files XPath-indexing is
225 enabled so that such records are searchable.
227 Zebra warns about missing .abs-file only once (for each type).
229 Fixed a bug in file update where already-inserted files could
234 Zebra license changed to GNU GPL.
236 XPath-like queries used when RPN string attributes are used, eg.
237 @attr 1=/portal/title sometitle
238 @attr 1=/portal/title[@xml:lang=da] danishtitle
239 @attr 1=/portal/title/@xml:lang da
240 @attr 1=//title sometitle
242 Zebra uses UTF-8 internally:
243 1) New setting "encoding" for zebra.cfg that specifies encoding for
244 OCTET terms in queries and record encoding for most transfer syntaxes
245 (except those that use International Strings, such as GRS-1).
246 2) The encoding of International strings is UTF-8 by default. It
247 may be changed by character set negotiation. If character set
248 negotiation is in effect and if records are selected for conversion
249 these'll be converted to the selected character set - thus overriding
250 the encoding setting in zebra.cfg.
251 3) New directive "encoding" in .abs-files. This specifies the external
252 character encoding for files indexed by zebra. However, if records
253 themselves have an XML header that specifies and encoding that'll be used
256 XML filter (-t grs.xml).
258 Multiple registers. New setting in resource 'root' that holds base
259 directory for register(s). A group a databases may be put in separate
260 register in directory root/reg by using db name 'reg/db1' ... 'reg/dbN'.
264 Fixes for Digital Unix
266 Implemented hits per term using USR:SearchResult-1.
268 New Zebra API. Locking system re-implemented.
270 --- 1.1.stable 2002/02/20
272 Rank weight can be controlled with attribute type 9. Default
273 value is 34. Recommended values between 1-36.
277 Updated for YAZ version 1.8.
279 Added support for termsets - a result set of terms matching
280 a given query. For @attr 8=<set> creates termset named <set>.
282 Added support for raw retrieval. Element Set Name R forces the
283 text filter which returns the record in its original form.
285 Added numerical sort - triggered by structure=numeric (4=109).
287 Remote record import using Z39.50 Extended Services and Segments.
289 Fixed bug where updating a database with user-defined attributes
290 could corrupt the register (bad storeKeys).
292 Multi-threaded version.
294 Fixed bug regarding proximity.
296 Documentation updates.
298 Fixed bug in record retrieval module that occured on 64-bit OSF
303 Fixed bug in makefile for WIN32.
305 Fixed bug in configure script - used bash-specific features.
309 Added support for multiple records in one file for filter grs.sgml.
311 Changed record index structure. New layout is incompatible with
312 previous releases. Added setting "recordcompression" to control
313 compression of records. Possible values are "none" (no
314 compression) and bzip2 (compression using libbz2).
316 Added XML transfer syntax support for retrieval of structured records.
317 Schema in CompSpec is recognised in retrieval of structured records.
319 Changed Tcl record filter so that it attemps to read <filt>.tflt. If
320 that fails, the filter reads the file <filt>.flt (regx style filter).
322 Implemented new Tcl record filter - use grs.tcl.<filter> to enable it.
323 Zebra's configure script automatically attempts to locate Tcl. For
324 manual Tcl configuration use option --with-tclconfig=<path> to specify
325 where Tcl's library files are located.
327 Implemented "compression" of Dictionary and ISAM system. Dictionary
330 Added "tagsysno" directive to zebra.cfg to control under which tag the
331 system ID is placed. Use tagsysno: 0 to disable Zebra's system number
334 Added "tagrank" as above.
336 Changed file naming scheme for register files from <name>.mf.<no> to
339 Implemented "position"-flag for register type (as defined in
340 default.idx). When set to zero no position (or seqence number) is
341 saved in register for each word occurrence, thus saving some register
344 Implemented database mapping. Using mapdb one can specify a database
345 to be mapped to one or more physical databases. Usage:
346 mapdb <fromdb> <todb> ..
348 Added SOIF-filter. Thanks to Peter Valkenburg.
350 For the regx-filter "end element -record" may trigger a mark-of-record
351 if outer level is reached.
353 Tag sets may be typed in the reference to it. From the .abs-file the
354 "tagset" directive takes a third optional integer type for the tag set
355 referenced. From a .tag-file the "include" directive takes a third
356 optional type as well. The old "type" directive in the tag set itself
357 is still recognized but acts as the default type for the tag set.
359 Zebra supports the specification of arbitrary attributes sets, schemas
360 and tag sets, because of the change in YAZ' OID management system.
362 Fixed bug in Sort that caused it NOT to use character mapping as it
365 Zebra now uses GNU configure to generate Makefile(s).
367 Added un-optimised support for left and left/right truncation attributes.
369 Added support for relational operators on text when using RPN queries.
371 Added support for sort specifications in RPN queries. Type 7 specifies
372 'sort' where value 1=ascending, value 2=descending. The use attribute
373 specifies the field criteria as usual. The term specifies priority
374 where 0=first, 1=second, ...
376 Changed the way use attributes are specified in the recordId
379 Maximum number of databases in one Zebra register increased.
381 New setting, databasePath, which specifies that first directory during
382 update traversal is the database name (instead of a fixed one).
384 New setting, explainDatabase, which specifies that databases are
387 Modified Zebra so that it works with ASN.1 compiled code for YAZ.
389 Implemented EXPLAIN database maintenance. Zebra automatically
390 generate - and update CategoryList, TargetInfo, DatabaseInfo,
391 AttributeSetInfo and AttributeDetails records at this stage. The
392 records may be transferred as GRS-1, SUTRS or Explain.
394 Fixed register spec so that colon isn't treated as size separator
395 unless followed by [0-9+-] in order to allow DOS drive specifications.
397 Fixed two bugs in ISAMC system.
399 Changed the way Zebra keeps its maintenance information about attribute
400 sets, available attributes, etc.. Records in "SGML" notation using an
401 EXPLAIN schema is now used when appropriate.
403 Bug fix: Index didn't handle update/insert/delete of the same record
404 (i.e. same recordId) in one run (one invocation of zebraidx). Only the
405 first occurence of a record is considered.
407 Most searches now return correct number of hits.
409 New modular ranking system. Interested programmers are encouraged to
410 inspect rank1.c and improve the algorithm.
412 Bug fix: Lock files weren't removed as they should on NT.
414 Implemented Z39.50 Sort. Zebra's sort handler uses use attributes to
415 specify a "sort register". Refer to the gils sample records which refer
416 to index type "s" which is specified as "sort" in the default.idx file.
417 Each sort criteria can either be Ascending or Descending and at most
418 three sort elements can be specified.
420 Bug fix: Character mapping didn't work for text files.
424 Simple ranked searches now return correct number of hits.
426 The test option (-s) only makes a read-lock on the index as well
427 as using read-only operations anywhere.
429 Moved towards generic character mapping. Configuration file default.idx
430 specifies character map files for register types w, p, u, etc.
432 Implemented "begin variant" for the sgml.regx - filter.
434 Fixed a few memory leaks.
436 Added support for C++, headers uses extern "C" for public definitions.
438 Bug fix: The show records facility (-s) only displayed information for
439 the first record in a file (and not for every record in the file).
441 Added option "-f <n>" to limit the logging of record operations. After
442 <n> records has been processed no logging is performed (unless errors
445 Bug fix: the compressed ISAM system didn't handle update operations
448 Added setting, "maxResultSetSize", to hold the number of records to
449 save in a result set.
451 Bug fix: Complete phrase did't work for search operations.
453 Bug fix: temporary result sets weren't deleted.
455 Reduced disk space for saved keys (storeKeys = 1).
457 Added optional, physical ANY (key replication)
459 Implemented proximity operator in search.
461 Bug fix: the path name buffers used by file match traversal routines
462 have been extended to support long file names.
464 New C(ompressed) ISAM system. To enable it, specify "isam: c" in the
465 configuration file. The resulting register without "storeKeys" is about
466 half the size, and the memory used by zebraidx during phase 2 (merge) is
467 reduced to a minimum.
469 Reworked the way Regexp-2 queries with error tolerance are handled and
470 specified. The documentation has been updated accordingly.
472 Bug fix: Zebrasrv didn't search correctly when queries contained masking
473 characters. This bug was introduced in 1.0a8.
475 Zebrasrv now tag records with the proper database name.
477 New settings, memMax and keyTmpDir.
479 Changed name of setting lockDir (previously called lockPath) and
480 setTmpDir (previously called tempSetPath).
482 Generalized and changed record type specifications. In short, there are:
484 grs.sgml structured, "SGML-like" syntax
485 grs.regx.<filter> structured, Regular expression filter
486 grs.marc.<abs> Reads *MARC records in the ISO2709 format. <abs>
487 is the name of an abstract syntax file.
488 Bug fix: Result sets weren't sorted in operations involving boolean
489 operations with "ranked" operands.
493 Added national character-handling subsystem.
497 Small modifications to input filters and profiles.
499 Added support for SOIF syntax (with private OID).
503 Fixed buffer-size problem in indexing.
505 Added compression to temporary files for updating.
507 Added phrase registers.
509 Added dynamic mapping of search attribute to multiple termlists (ANY).
511 Scan support in multiple databases/registers.
513 Configuration settings are case-insensitive and single dash (-)
514 characters are ignored in comparisons.
516 The index processing ignores empty files - warning given.
518 New option to zebraidx (-V) displays version information.
522 Fixed problem in file-update system.
524 Fixed problem in shadow system; register was sometimes corrupted after
529 Fixed problems in the ISAM subsystem. Caused difficulties when updating
532 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
533 the rank and record number.
535 Fixed bug in the isam subsystem - caused a malfunction when accessing
536 words which occurred more than 10000 times.
538 Distribution should now include YAZ (Z39.50 protocol stack) to simplify
541 Server can now run under inetd. Use option -i, and -w <directory> to
542 set working directory to desired location.
544 New zebraidx command: clean - removes temporary shadow files.
546 Fixed bug in ISAM system. Occurred rarely during register updates.
548 Logging during index merge phase is improved. The remaining running
551 Temporary files generated by zebraidx are removed after each run.
553 Bug fix: Dictionary didn't handle 8-bit characters correctly; was obvious
554 when doing scan operations in dictionaries with European characters.
558 A whole slew of updates, to make the first publicized release. Get the doc
563 Memory-problems in ISAM fixed. More blocktypes added to the default setup
564 to increase performance on larger databases.
566 Various minor changes in data management system.
570 A couple of portability-problems resolved.
572 Changed some malloc() to xmalloc().
