Bug#663056: libsoup2.4: FTBFS on kfreebsd-*: test-suite FAIL: context-test

[Steven Chamberlain]

Hi again,

I've narrowed down the context-test failures to g_cond_wait_until [1]
returning false without actually waiting until the requested time.

Test case with extra debug info:

>         time = g_get_monotonic_time () + 5 * G_TIME_SPAN_SECOND;
> debug_printf (1, "  g_cond_wait_until %lu\n", time);
>         if (g_cond_wait_until (&test1_cond, &test1_mutex, time))
>                 g_thread_join (thread);
>         else {
> time = g_get_monotonic_time ();
> debug_printf (1, "  returned false at %lu\n", time);
>                 debug_printf (1, "  timeout!\n");
>                 g_thread_unref (thread);
>                 errors++;
>         }

Result:

> Test 1: blocking the main thread does not block other thread
> (Using SOUP_SESSION_ASYNC_CONTEXT)
>   g_cond_wait_until 2863968386
>   returned false at 2858968977
>   timeout!


Under gdb we hit a familiar-looking issue that I'm sure we've seen
before on kfreebsd:
