0.50 Wed Sep 7 01:36:18 2005
- add correspondence between BufCaElt and RDBlock via the
MailBag
- add hooks for _BCE_dirtyhook, _init_filewriteblock
0.49 Sun Aug 28 22:24:16 2005
- Util::FileSetHeaderInfo - method to add defs to existing datafile
0.48 Fri Aug 26 23:33:21 2005
- Consolidate all dictionary defs/prefs, see "dump prefs"
0.47 Thu Aug 25 02:03:21 2005
- Object-Oriented SysHook
- arbitrary user preferences (via -define) and fileheader info
(via -fileheader_define).
- align fileheader on blocksize boundary
0.46 Sun Aug 7 20:10:17 2005
- more efficient update of rows that exceed small row threshold.
- add sync (flush changes to disk without committing a transaction).
initialization (e.g. blocksize=2k).
Fix rowcount in DBI fetch (GenDBI::SelectFetch).
Cleanup Tablespace handling of filearr,used/unused to match
Dict _tsfiles fileidx.
Use Util::UNPACK_TEMPL_ARR to cache common unpacking templates
to speed up UnPackRow.
bt2: faster insertion
0.11 Tue Mar 30 23:14:54 2004
- change col1 and pref1 column names so not reserved words,
fix bufcache creation to get size from prefs, use all free
blocks before checking pin status, parse IS [NOT] NULL
predicates
0.10 Fri Mar 19 23:59:46 2004
- describe table, better string parsing of relop tokens
(e.g. =, <, > ...), primitive sql update (basically single
row update column=value, no subqueries), slight fixes on
RSFile/SMFile nextblock improve row packing density, remove
surrounding quotes on insert/update values, return undef's in
SelectFetch (versus the string "<undef>"), quiet undef warnings
