a worse execution plan than in 4.1 for some queries.
It happened due the fact that at some conditions the
optimizer always preferred range or full index scan access
methods to lookup access methods even when the latter were much
cheaper.
The problem was not observed in 4.1 for the reported query
because the WHERE condition was not of a form that could
cause the problem.
Equality propagation introduced on 5.0 added an extra
predicate and changed the WHERE condition. The new condition
provoked the optimizer to make a bad choice.
The problem was fixed by the patch for bug 17379.

When a view statement is compiled on CREATE VIEW time, most of the
optimizations should not be done. Finding the right optimization
for a subquery is one of them.
Unfortunately the optimizer is resolving the column references of
the left expression of IN subqueries in the process of deciding
witch optimization to use (if needed). So there should be a
special case in Item_in_subselect::fix_fields() : check the
validity of the left expression of IN subqueries in CREATE VIEW
mode and then proceed as normal.

garbles data if longer than 766 chars.
The problem is that a stored routine returns BLOBs to the previous
caller, BLOBs are shallow-copied (i.e. only pointers to the data are
copied). The fix is to also copy data of BLOBs.

- Fix mysqld_safe so that it always passes correct --log-error argument to mysqld
- A few other minor clean-ups to mysqld_safe
scripts/mysqld_safe.sh:
Bug #6061 mysql-log-rotate script - error logging doesn't use new file
- Change mysqld_safe to pass --log-error to mysqld in all cases. The old behavior was to usually "swallow" the --log-error=file.name argument, which caused mysqld to write to stderr and not be able to flush the error log file. Ironically, passing --log-error (with no file name) seemed to work fine, because mysqld_safe didn't recognize it and passed it on to mysqld as an unknown option.
- Ensure that the error log file matches what mysqld uses; in particular, add ".err" if given a --log-error argument with no extension, and add "$DATADIR" to the front of a relative path
- Various other mysqld_safe clean-ups while there - quote arguments properly, remove some redundant code
