Description:
backup_backupdir.test fails on sapsrv1:

main.backup_backupdir          [ fail ]

mysqltest: At line 91: query 'BACKUP DATABASE bup_backupdir TO '$MYSQLTEST_VARDIR/master_data/not/there/either/bup_backupdir6.bak';' failed with wrong errno 2013: 'Lost connection to MySQL server during query', instead of 1632...

The result from queries just before the failure was:
< snip >
BACKUP DATABASE bup_backupdir TO '../../bup_backupdir3.bak';
backup_id
#
Ensure backup image file went to the correct location
Reset backupdir with ending /
SET @@global.backupdir = '../tmp/backup/';
Perform backup
BACKUP DATABASE bup_backupdir TO '../../bup_backupdir4.bak';
backup_id
#
Ensure backup image file went to the correct location
Try a backup to an invalid relative path.
BACKUP DATABASE bup_backupdir TO '../not/there/bup_backupdir5.bak';
ERROR HY000: Can't write to backup location '../not/there/bup_backupdir5.bak' (file already exists?)

Try a backup to an invalid hard path.
*Actual BACKUP DATABASE command not printed due to non-deterministic path.
*Performing: 
*BACKUP DATABASE bup_backupdir TO '$MYSQLTEST_VARDIR/master_data/not/there/either/bup_backupdir6.bak';
ERROR HY000: Lost connection to MySQL server during query

How to repeat:
Pushbuild on sapsrv1, not sure why this server fails and other linux servers don't.

      Bug#39189 - Backup: backup_backupdir.test fails in pushbuild
      
      Old behavior: When giving hard path to backup command, a '/' was 
      appended at the end of the path (i.e., after the filename). 
      This was because the whole path was converted to fit the system. 
      
      New behavior: Only the directory name is converted to system. The
      filename is then appended without conversion.

      done with explicit path length

Pushed to 6.0 main for 6.0.8
[29 Sep 2008 17:25] Paul DuBois 
Noted in 6.0.8 changelog.

For BACKUP DATABASE, the server could add a / character to the end of
the backup path, even when the path ended with a filename rather than
a directory name.
