Cannot catch before if program exits immediately

[raczben]

Issue: wexpect cannot wait on EOF properly. The before field wont contain the program's output if it has no prompt.

Reproduce:

import wexpect
import time
p = wexpect.spawn('uname')
time.sleep(1)
p.expect(wexpect.EOF)
p.before

tests.test_constructor.TestCaseConstructor.test_constructor testcase fails due to this issue.

Here is a workaround:

insert the following line at the end of the _spawn() function of the spawn_windows class. (~ line: 1740)

        try:
            self.expect(EOF, timeout = 0)
        except:
            pass

similarly, you can't get the output to print for debugging/monitoring... i.e.

import wexpect
import time
import sys
p = wexpect.spawn('uname')
p.logfile_read = sys.stdout
time.sleep(1)
p.expect(wexpect.EOF)
p.before

This issue will be solved when the new-structure-wexpect will be stable and default.

Fixed in v4.0.0
