The patch implements the idea suggested by Olaf van der Spek in
thread "Client: many small reads?" (internals@lists.mysql.com).
Now small reads performed by the client library are buffered.
The buffering gives up to 2 times speedup when retrieving
one-column tables.
Add support for VARCHAR with 1 or 2 length bytes
Enable VARCHAR packing in MyISAM files (previous patch didn't pack data properly)
Give error if we got problems in temporary tables during a SELECT
Don't use new table generated by ALTER TABLE if index generation fails
Fixed wrong call by range_end() (Could cause an ASSERT in debug mode)
FOUND is not a reserved keyword anymore
Added Item_field::set_no_const_sub() to be able to mark fields that can't be substituted
Added 'simple_select' method to be able to quickly determinate if a select_result is a normal SELECT
Note that the 5.0 tree is not yet up to date: Sanja will have to fix multi-update-locks for this merge to be complete
(All commit emails since 4.0.1 checked)
This had to be done now, before the 4.1 tree changes to much, to make it easy to propagate bug fixes to the 4.1 tree.
Fixes for building MySQL with gcc 3.0
Added SIGNED / UNSIGNED casts
Fixed core dump bug in net_clear() with libmysqld.
Back to using semaphores in query cache.
Added 'Null' and 'Index_type' to SHOW INDEX.
TODO is --with-cpu configure option to force some other processor type.
Problem is not big as any Intel 686+ CPU will use -mcpu=pentiumpro anyway. Exceptions are Athlons and 586 processors.
compiles, passes test suite, does magic, has bugs, but none that I know
at this point. Have not tested everything yet, though. Changed
a lot of code in the client, but normal stuff appears to be working.
fix to make ENCRYPT work
BUILD/compile-pentium-debug
debug has different warnings
BUILD/FINISH.sh
save symbol table and dissassembled code with symobls available before strip
use $do_make for make decision instead of $make to avoid conflict
BUILD/SETUP.sh
export AM_MAKEFLAGS
fast is now -fno-omit-frame-pointer, the opposite is now called
reckless
configure.in
fixes to make CRYPT work again
Docs/Makefile.am
hack to avoid rebuilding the manual on make clean -why does
Makefile depend on $BUILD_SOURCES, and do we even need BUILD_SOURCES?
