Test tty-test.cpp fails in src/tests/add-ons/kernel/drivers/tty/

[Karvjorm]

When I tried to build tty-test.cpp in src/tests/add-ons/kernel/drivers/tty/, I got an error message from the following line:

printf("e: %d\n", err);

err is here of status_t type. After commenting out that line I was able to build application but testing failed in TestUnblockOnCloseRead(false, true) or TestUnblockOnCloseRead(false, false) after first TestUnblockOnCloseRead(true, false) test in Test() method when doing CHK_ALIVE(thread) test.

When I commented out the second and third test, then test program fails when RUN_TEST(new TestSelectNotifyOnClose(true)) is called:

RUN_TEST(new TestUnblockOnCloseRead(true,  false));
//RUN_TEST(new TestUnblockOnCloseRead(false, false));
//RUN_TEST(new TestUnblockOnCloseRead(false, true));

RUN_TEST(new TestUnblockOnCloseWrite(true,  false, false));
RUN_TEST(new TestUnblockOnCloseWrite(false, false, false));
RUN_TEST(new TestUnblockOnCloseWrite(true,  true,  false));
RUN_TEST(new TestUnblockOnCloseWrite(false, true,  false));
// TODO: How to enable echo mode?
// RUN_TEST(new TestUnblockOnCloseWrite(true,  false, true));
// RUN_TEST(new TestUnblockOnCloseWrite(false, false, true));
// RUN_TEST(new TestUnblockOnCloseWrite(true,  true,  true));
// RUN_TEST(new TestUnblockOnCloseWrite(false, true,  true));

// select tests

RUN_TEST(new TestSelectAlreadyReady(true,  true));
RUN_TEST(new TestSelectAlreadyReady(false, true));
RUN_TEST(new TestSelectAlreadyReady(true,  false));
RUN_TEST(new TestSelectAlreadyReady(false, false));

RUN_TEST(new TestSelectNotifyOnClose(true));
RUN_TEST(new TestSelectNotifyOnClose(false));

No clue what these tests even do.

It was 9 years ago, but you wrote them (according to the git log and copyright message at least).

Yes, and I'm sure they where useful back then. I don't know, whether they still are and when they stopped working. François added a test on 2010-03-28, predating this ticket, so I assume they did still work back then. My last change to the TTY driver code was before that, on 2010-03-04.

At any rate, I don't think I'll work on this any time soon.
