subrepo: replace "_calcfilehash" invocation by "vfs.tryread"
"_calcfilehash" can be completely replaced by simple "vfs.tryread"
invocation.
def _calcfilehash(filename):
data = ''
if os.path.exists(filename):
fd = open(filename, 'rb')
data = fd.read()
fd.close()
return util.sha1(data).hexdigest()
Building absolute path "absname" up by "self._repo.join" for files in
"filelist" is avoided, because "vfs.tryread" does so internally.
# Disable the $CAP wire protocol capability.
if test -z "$CAP"
then
echo "CAP environment variable not set."
