[Qemu-devel] [PATCH] qemu-iotests: stop using /tmp directly


From: Peter Wu
Subject: [Qemu-devel] [PATCH] qemu-iotests: stop using /tmp directly
Date: Fri, 22 Aug 2014 13:25:43 +0200

Before this patch you could not run multiple tests concurrently as they
might clobber each other test files. This patch solves that by using
random temporary directory instead of `/tmp` (for writing output in the
individual tests and valgrind logs).

Furthermore, this patch stops removing everything in `/tmp/` matching a
certain pattern (`/tmp/*.{err,out,time}`). These might not be a property
of QEMU.

Running multiple concurrent tests in the same object directory is still
not supported though as the scratch directory and .bad and .notrun files
still interfere with each other. Also not touched is the situation that
/tmp/check.log and /tmp/check.sts are hard-coded (and thus unusable in
concurrent tests).

Hi,

This patch introduces a dependency on mktemp of coreutils. I could still not get
concurrent tests to work fully reliably (test 030 failed randomly with QED):

    FAIL: test_ignore (__main__.TestEIO)
    ----------------------------------------------------------------------
    Traceback (most recent call last):
      File "030", line 223, in test_ignore
        self.assert_qmp(result, 'return[0]/paused', False)
      File "/tmp/qemu/tests/qemu-iotests/iotests.py", line 233, in assert_qmp
        result = self.dictpath(d, path)
      File "/tmp/qemu/tests/qemu-iotests/iotests.py", line 221, in dictpath
        self.fail('invalid index "%s" in path "%s" in "%s"' % (idx, path, 
str(d)))
    AssertionError: invalid index "0" in path "return[0]/paused" in "[]"

I still think that the patches are valuable though, it reduces predictable file
names.

Kind regards,
Peter
