libdispatch Arch Linux


(Ryan Lovelett) #1

(I know that this is not 100% expected to work yet. AND I'm working on
an unsupported distro... but I thought I'd ask).

Trying to build libdispatch on Linux (Arch Linux 4.6.4-1-ARCH). The
build seems to go fine up until the tests. At this point there are 3
failing tests (see the attached test-suite.log).

Two questions:

1. Can someone help me decipher that log to figure out what is going
wrong?
2. It tells me to report the errors to libdispatch@macosforge.org. Is
that something I really should do?

Hi Ryan:

The three failures:
dispatch_select:
dispatch_io
dispatch_io_net

most likely occur because you don't have a /usr/share/dict/words file,
which you can get by installing something like the wamerican or wbritish
backage.

Chris/David,

Thank you for the responses! That got rid of 2/3rds of the test
failures.

However, the `dispatch_io` test is still failing. I've added the test-
suite.log once more.

Again thanks for the help!

Hi Ryan,

  The test that is failing creates a temporary directory, sets it to be
read-only, and then attempts to write into the directory. It is expecting
the write to fail with errno value EACESS (13). Instead, the write attempt
is succeeding (errno is 0).

  I'd guess that either you are running the test as root/sudo or the
chmod operation on the temporary directory to make it read-only failed.

--dave

[BEGIN] error from write to write protected directory
  Actual: 0
  Expected: 13 Permission denied
[FAIL] error from write to write protected directory (dispatch_io.c:611)
  dispatch_io.c:611

That seems about right. The tests run in a chroot, where the script is
root, to ensure that I control dependencies and such.

Not sure what I I can do about this test. :thinking:

Thanks for the help Dave!
