From 54423d0151eebde19eaeb7bb32fd2368e9e6319e Mon Sep 17 00:00:00 2001 From: Jeremy Stanley Date: Sat, 30 Jun 2018 20:52:23 +0000 Subject: [PATCH] Test that ANSI input is filtered Add a simple regression test to make sure ANSI escape sequences aren't allowed in input lines. The escape (byte \x1b) character should be filtered from non-binary-mode clients because we filter to a "printable" set. For binary-mode clients an escape won't be valid UTF-8 and so will cause the entire line of input on which it's found to be skipped. --- mudpy/tests/selftest.py | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/mudpy/tests/selftest.py b/mudpy/tests/selftest.py index e120e70..0b29386 100644 --- a/mudpy/tests/selftest.py +++ b/mudpy/tests/selftest.py @@ -101,6 +101,11 @@ test_wrapping = ( (1, r'says,\r\n"O[o]+\."', ""), ) +test_forbid_ansi_input = ( + (0, '> ', "say \x1b[35mfoo\x1b[0m"), + (1, r'says, "\[35mfoo\[0m\."', ""), +) + test_movement = ( (0, "> ", "move north"), (0, r"You exit to the north\.", ""), @@ -263,6 +268,7 @@ dialogue = ( (test_sentence_capitalization, "sentence capitalization"), (test_chat_mode, "chat mode"), (test_wrapping, "wrapping"), + (test_forbid_ansi_input, "raw escape input is filtered"), (test_movement, "movement"), (test_actor_disappears, "actor spontaneous disappearance"), (test_account1_teardown, "second account teardown"), -- 2.11.0
