Fixed the references to security_ctx->priv_user
to be real char * pointers instead of a C array name reference.
This is somehow important for some 3d party
dtrace replacements
DROP/CREATE SCHEMA, CREATE TABLE, REPAIR.
The cause of assert was concurrent execution of
DROP DATABASE and REPAIR TABLE where first statement
deleted table's file .TMD at the same time as
REPAIR TABLE tried to read file details from the old file
that was just removed.
Additionally was fixed trouble when DROP TABLE try delete
all files belong to table being dropped at the same time
when REPAIR TABLE statement has just deleted .TMD file.
No regression test added because this would require adding a
sync point to mysys/my_redel.c. Since this bug is not present in
5.5+, adding test coverage was considered unnecessary.
The patch has been verified using RQG testing.
mysqltest checks if the stmt is one that should be run in ps mode,
but regexp doesn't match if preceeded by /* */ comment.
Fix: match function will jump over /*..*/ if found at start
Backported use of setenv() from 5.5
This will remove the leak on systems that have setenv()
I have not fixed the string.c leak, it's a local variable
that the cleanup function cannot access.
Var's string value was not 0-terminated if intially null.
While at it, also removed some reported memory leaks
Added sanity check, setting val_len=0 if val==0
when semijoin=on
When setting the aggregate function as having no rows to report
the function no_rows_in_result() was calling Item_sum::reset().
However this function in addition to cleaning up the aggregate
value by calling aggregator_clear() was also adding the current
value to the aggregate value by calling aggregator_add().
Fixed by making no_rows_in_result() to call aggregator_clear()
directly.
Renamed Item_sum::reset to Item_sum::reset_and_add() to
and added a comment to avoid misinterpretation of what the
function does.
Before this fix, the output of SHOW ENGINE PERFORMANCE_SCHEMA STATUS
used uppercase to name performance schema tables.
This is inconsistent since performance schema tables have been renamed to lowercase.
Also, an old table 'PROCESSLIST' was still visible,
even after this table got renamed to 'threads'.
This fix:
- correctly uses lowercases in the output, to match the current naming.
- replaced 'PROCESSLIST' with 'threads'.
Tested the output of SHOW ENGINE PERFORMANCE_SCHEMA STATUS manually.
No automated test cases can be written for this,
since the output is too platform dependent (sizes).
Manual merge from mysql-5.1-bugteam into mysql-5.5-bugteam.

command line clients.
Command line tools like mysqladmin and mysqldump did not recognize
default-auth and plugin-dir options.
Support for these options was found missing in these command line
tools.
Fixed by adding support for the same.
Problem: "read-only" option ignored if it's enabled in
the command line (or in the config file).
Fix: sync opt_readonly (which is used for checks) with
read_only (global var) when all server options are handled.
When a query fails with a different error on the slave,
the sql thread outputs a message (M) containing:
1. the error message format for the master error code
2. the master error code
3. the error message for the slave's error code
4. the slave error code
Given that the slave has no information on the error message
itself that the master outputs, it can only print its own
version of the message format (but stripped from the
additional data if the message format requires). This may
confuse users.
To fix this we augment the slave's message (M) to explicitly
state that the master's message is actually an error message
format, the one associated with the given master error code
and that the slave server knows about.
