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