Mismatches in 'exact tstamps' tests

[eserte]

Another fail pattern:

# Failed test 'exact tstamps'
# at t/cron.t line 94.

t/cron.t ......... 
Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/3 subtests 

Something similar happens with t/one_crontab.t

That test failing means no cron lines were executed. I tried to reproduce this failure on Ubuntu, Windows or Mac, but I couldn't. Can you share the OS / Configuration on the problematic platform?

update: I see it failing in Travis builds, will check that

[eserte]

I don't see a pattern: I count 16 configurations where this test is failing, with perl versions from 5.16.3 to 5.27.11, and different OS: freebsd 9.2, freebsd 10.3, debian jessie+stretch, CentOS6.

That happened when EV module was installed. I ended up adding at the very beginning of both test these to lines that happen to be on all Mojo::IOLoop related tests in Mojolicious distributions:

BEGIN {
  $ENV{MOJO_REACTOR} = 'Mojo::Reactor::Poll';
}

This forces to use Mojo::Reactor::Poll instead of Mojo::Reactor::EV. So I am not sure the tests are valid when Mojolicious uses EV. I have to ask at #mojo channel, maybe someone can explain me if the tests are enough.

Please let me know if tests are passing now

Doesn't reproduce after forcing Mojo::Reactor::Poll in tests.
