Hah, you should have told me you have a tachyonic input device. This event goes back in time, which caused a 2^32 ms sleep. Fixed in f70d31a

I suppose this will work if you fcntl it to a non-blocking read. I suppose this isn't treated as an EOF as the process is still somewhat lingering (zombie). It might also work to move the read after the waitpid(), I haven't tried that.

int status;
Posix.waitpid (evemu_record_pid, out status, 0);
Process.close_pid (evemu_record_pid);
/*
if (serr_len > 0) {
serr[serr_len] = 0;
stderr.printf ("evemu-record error: %s\n", (string) serr);
Process.abort();
}
*/
string[] output_lines = ((string)sout).split("\n");
string[] input_lines = evemu_script.split("\n");

These two need an extra .strip() before the split, to avoid a trailing element with an empty line (which won't match the RE below).

int output_offset = 0;

// Find the start of the events in evemu-record output
foreach (var line in ((string)sout).split("\n")) {
if (line.has_prefix("E:"))
break;
output_offset++;
}

// XXX: Debug output while the test is failing...
stdout.printf("Output is:\n%s\n", (string)sout);

// We should have exactly the same number of events
assert_cmpint(output_lines.length - output_offset, Op.EQ, input_lines.length);

var event_re = new Regex("^E: ([0-9]+)\\.([0-9]+) +([0-9a-fA-F]+) +([0-9a-fA-F]+) +(-?[0-9]+) *#?");
MatchInfo input_match, output_match;
for (int i = 0; i < output_lines.length; i++) {

This needs to be "< input_lines.length".

assert (event_re.match(input_lines[i], 0, out input_match));
assert (event_re.match(output_lines[i + output_offset], 0, out output_match));

// We care to match device ID, event type, and event value
// Because the timestamps are so fine-grained, they probably won't match exactly

assert_cmpstr(input_match.fetch(5), Op.EQ, output_match.fetch(5));
