# ==== Purpose ====
|
|
#
|
|
# Write the contents of $write_var to file $write_to_file.
|
|
#
|
|
#
|
|
# ==== Usage ====
|
|
#
|
|
# --let $write_var = <value>
|
|
# --let $write_to_file = [<file>|GENERATE]
|
|
# --source include/write_var_to_file.inc
|
|
#
|
|
# $write_var is evaluated in sql 'string' context, so escapes like \n
|
|
# are interpolated.
|
|
#
|
|
# $write_to_file can be either a filename, or the special string
|
|
# GENERATE. If it is GENERATE, a unique filename is generated (based
|
|
# on UUID()). The filename is saved in $write_to_file so that it can
|
|
# be retrieved later.
|
|
#
|
|
#
|
|
# ==== Implementation ====
|
|
#
|
|
# We can't use mysqltest's write_file because it does not evaluate
|
|
# variables. We can't use '--exec echo $write_var > $write_file'
|
|
# because it will use \n\r line terminator under windows. So the only
|
|
# working way is mysql's SELECT INTO DUMPFILE, which is subject to
|
|
# @@secure_file_priv. That makes this more complex than you might
|
|
# expect.
|
|
|
|
if (!$write_to_file)
|
|
{
|
|
--die You must set the mysqltest variable \$write_to_file before you source include/write_var_to_file.inc
|
|
}
|
|
|
|
if ($write_to_file == 'GENERATE')
|
|
{
|
|
--let $_wvtf_suffix= `SELECT UUID()`
|
|
--let $write_to_file= $MYSQLTEST_VARDIR/tmp/_var_file_$_wvtf_suffix.inc
|
|
}
|
|
|
|
--error 0,1
|
|
--remove_file $write_to_file
|
|
|
|
if (`SELECT LENGTH(@@secure_file_priv) > 0`)
|
|
{
|
|
--let $_wvtf_secure_file_priv= `SELECT @@secure_file_priv`
|
|
--let $_wvtf_suffix= `SELECT UUID()`
|
|
--let $_wvtf_tmp_file= $_wvtf_secure_file_priv/_wvtf_$_wvtf_suffix
|
|
|
|
--eval SELECT '$write_var' INTO DUMPFILE '$_wvtf_tmp_file'
|
|
--copy_file $_wvtf_tmp_file $write_to_file
|
|
--remove_file $_wvtf_tmp_file
|
|
}
|
|
if (`SELECT LENGTH(@@secure_file_priv) = 0`)
|
|
{
|
|
--eval SELECT '$write_var' INTO DUMPFILE '$write_to_file'
|
|
}
