ChangeSet
  1.2318 05/06/24 17:14:16 jimw@stripped +1 -0
  Fix handling of datadir by mysqld_safe to support specifying a
  different DATADIR via the command line or during ./configure and
  still starting up mysqld_safe via a relative path. (Bug #7249)

  scripts/mysqld_safe.sh
    1.75 05/06/24 17:14:13 jimw@stripped +29 -11
    Decouple figuring out which BASEDIR and DATADIR to use so that
    the only DATADIR we'll try to use without first verifying that
    it exists is the compiled-in default.

# This is a BitKeeper patch.  What follows are the unified diffs for the
# set of deltas contained in the patch.  The rest of the patch, the part
# that BitKeeper cares about, is below these diffs.
