Initialized usable_keys from table->keys_in_use instead of ~0
in test_if_skip_sort_order(). It was possible that a disabled
index was used for sorting.
Version for 4.0.
It fixes two problems:
1. The cause of the bug was that we did not check the table version for
the HANDLER ... READ commands. We did not notice when a table was
replaced by a new one. This can happen during ALTER TABLE, REPAIR
TABLE, and OPTIMIZE TABLE (there might be more cases). I call the fix
for this problem "the primary bug fix".
2. mysql_ha_flush() was not always called with a locked LOCK_open.
Though the function comment clearly said it must.
I changed the code so that the locking is done when required. I call
the fix for this problem "the secondary fix".
directory - these files are now maintained in the mysqldoc
repository and included in the source distribution during the
release build. Updated the configure.in script and Makefiles to
create the man page file list at build time
- Updated the file list in the RPM spec file to include all currently
available man pages (this can not be done with wildcards, as
the man pages are spread across several subpackages. However, RPM
warns about unpackaged files, so newly added man pages can be
spotted)
Option to set environment variable MTR_BUILD_THREAD to a small
number, from what mysql-test-run calculate port numbers that
will not conflict with other runs with different thread num
DISTINCT wasn't optimized away and caused creation of tmp table in wrong
case. This result in integer overrun and running out of memory.
Fix backported from 4.1. Now if optimizer founds that in result be only 1
row it removes distinct.
1. it's wrong to use memcpy() for overlapped areas;
2. we use it only once.
During merge to 4.1 will remove a memcpy_overlap() call
from strings/ctype-tis620.c as well in order to fix
bug #10836: ctype_tis620 test failure with ICC-compiled binaries on IA64.
When fixing Item_func_plus in ORDER BY clause field c is searched in all
opened tables, but because c is an alias it wasn't found there.
This patch adds a flag to select_lex which allows Item_field::fix_fields()
to look up in select's item_list to find aliased fields.
The problem was an ab-use of last_rkey_length.
Formerly we saved the packed key length (of the search key)
in this element. But in certain cases it got replaced by
the (packed) result key length.
Now we use a new element of MI_INFO to save the packed key
length of the search key.
Solution for 4.0 and 4.1.
If the caller cannot re-open table(s), it gives a NULL
'refresh' argument to open_table(). We used to ignore
flushes then. Now we ignore drops too.
