Feature: Utilities that do NOT depend on WordPress code

Scenario Outline: Check that `proc_open()` and `proc_close()` aren't disabled for `Utils\run_mysql_command()`

When I try `{INVOKE_WP_CLI_WITH_PHP_ARGS--ddisable_functions=<func>} --skip-wordpress eval 'WP_CLI\Utils\run_mysql_command( null, array() );'`

Then STDERR should contain:

"""

Error: Cannot do 'run_mysql_command': The PHP functions `proc_open()` and/or `proc_close()` are disabled

"""

And STDOUT should be empty

And the return code should be 1

Examples:

| func |

| proc_open |

| proc_close |

Scenario Outline: Check that `proc_open()` and `proc_close()` aren't disabled for `Utils\launch_editor_for_input()`

When I try `{INVOKE_WP_CLI_WITH_PHP_ARGS--ddisable_functions=<func>} --skip-wordpress eval 'WP_CLI\Utils\launch_editor_for_input( null, null );'`

Then STDERR should contain:

"""

Error: Cannot do 'launch_editor_for_input': The PHP functions `proc_open()` and/or `proc_close()` are disabled

"""

And STDOUT should be empty

And the return code should be 1

Examples:

| func |

| proc_open |

| proc_close |

# INI directive `sys_temp_dir` introduced PHP 5.5.0.

@require-php-5.5

Scenario: Check `Utils\get_temp_dir()` when `sys_temp_dir` directive set

# `sys_temp_dir` set to unwritable.

When I try `{INVOKE_WP_CLI_WITH_PHP_ARGS--dsys_temp_dir=\\tmp\\} --skip-wordpress eval 'echo WP_CLI\Utils\get_temp_dir();'`

Then STDERR should contain:

"""

Warning: Temp directory isn't writable

"""

And STDERR should contain:

"""

\tmp/

"""

And STDOUT should be:

"""

\tmp/

"""

And the return code should be 0

# `sys_temp_dir` unset.

When I run `{INVOKE_WP_CLI_WITH_PHP_ARGS--dsys_temp_dir=} --skip-wordpress eval 'echo WP_CLI\Utils\get_temp_dir();'`

Then STDOUT should match /\/$/
