...and added new test file, sp-threads, for multiple connection tests
  (apart from the security tests that are in sp-security).

  The description is not entirerly correct. The issue was follow-up errors
  where the first error is not caught - in which case it's often a system
  error with errcode < 1000 (which are mapped by default to 'HY000'). In this
  case the error state is different from what was assumed in the execution
  loop.

  and tried to do it properly this time, digging out all show commands that
  need the multi results flag set.

The fix makes client_test.cc compile with embedded library.

should've been fixed as well.

- client side part is simple and may be considered stable
- server side part now just joggles with THD state to save execution
  state and has no additional locking wisdom.
  Lot's of it are to be rewritten.

   5.0.1 is out
 - tagged ChangeSet@1.1698 as "mysql-5.0.1"

Added a simple optimizer that shortcuts jumps and skip unused instructions.

Simply disallow it, just as we disallow creation of routines from within
other SPs.

at least partially. It doesn't crash or give packets out of order
any more, but it's unclear why it doesn't actually return anything
from within an SP. This should be investigated at some point, but
for the moment this will have to do. (It is a rather obscure feature... :)

non-ascii filenames work weird (e.g. on MacOSX)

(including one which may explain autobuild's failure of yesterday)

(The fix was merged in from 4.1)

Fix for stored procedures BUG#4726: Stored procedure crash when looping over SELECT with complex WHERE's.

  mysqld crashes on CREATE TABLE in a database with corrupted db.opt file.
  Bug#4646

Accidently worked on many platforms, but not all.

into neptunus.(none):/home/magnus/mysql-4.1

into sanja.is.com.ua:/home/bell/mysql/bk/work-5.0

made different fields for view updatebility in principle and updatability during this execution (BUG#4601)

Sub-CALLs of procedures zapped thd->current_arena for good.

fixed error handling
