feature #8655 Adds PTY mode & convenience method mustRun() (schmittjoh)
This PR was merged into the 2.5-dev branch. Discussion ---------- Adds PTY mode & convenience method mustRun() This makes two additions. I've split them into separate commits so that you can pull them separately if required. 1. Adds PTY mode. In contrast to the existing TTY mode, the proc_open call becomes the master not the process currently executing. 2. Adds a ``mustRun`` method This is merely for convenience: ```php # Before $proc = new Process($cmd); if (0 !== $proc->run()) { throw new ProcessFailedException($proc); } $proc = new Process($cmd); if (0 !== $proc->run()) { throw new ProcessFailedException($proc); } # After (new Process($cmd))->mustRun(); (new Process($cmd))->mustRun(); Commits ------- dbd264a adds cache for isPtySupported() 6c11207 attempts to fix tests on Travis 2ff1870 adds convenience method mustRun 53441aa adds support for PTY mode
