Crash may happen when selecting from a merge table that has underlying
tables with less indexes than in a merge table itself.
If number of keys in merge table is not bigger than requested key number,
return error.
Fixed confusing error message from the storage engine when
it fails to open underlying table. The error message is issued
when a table is _opened_ (not when it is created).
This is a replacement for the original patch given by Ingo. This one comes
from Monty.
The problem is that merge files now use unix style pathnames on all
platforms. The merge file open code was not properly converting those
pathnames back to non-unix when necessary.
Changed the creation of the .MRG file so that only the table name
is written when the MyISAM table is in the same database as the
MERGE table, a relative path is used in other cases in mysqld,
and possibly an absolute path is used in an embedded server.
No test case is added as the external behaviour is unchanged.
Only the file names within the .MRG file are changed.
Use 'mysqltest' as test database instead of test_$1 or test1,test2 to not accidently delete an important database
Safety fix for mailformed MERGE files
Speed up column-completion in 'mysql'
Don't use ISAM if HAVE_ISAM is not defined
A lot of fixes for the embedded version. All libraries are now included in libmysqld.a
Changed arguments to convert_dirname() to make it more general.
Renamed files in the 'merge' directory to all use a common prefix.
Don't compile both assembler and C functions on x86
added system command
myisammrg/myrg_open.c
fixed coredump when opening an empty union table
sql/sql_repl.cc
fixed warnings, remove confusing comment, fixed coredump in
change master to when master.info was corrupted
added new replication test case
