Hi,
I would like to add non-blocking process execution in varnishtest,
something different than the existing shell and err_shell commands.
I have found several use cases:
- testing varnish tools (there's a varnishncsa test)
- running unrelated programs (eg. redis for a redis vmod)
- attach strace to a pid (varnish or other process)
The second patch introduces a new macro for "-n" options, eg. ${v1_name}.
This was inspired by #1742.
Of course it's useless for all interactive executions, but you can
currently start a process, send signals, write to its stdin, and
stdout/err redirection to files... That's probably enough for many
use cases.
I haven't done much more (like -expect on the status code) because
it can easily be added afterwards if needed.
Best Regards,
Dridi

Subject: [PATCH 1/2] Run background processes in varnishtest
Available operations on processes are:
- start
- wait
- kill (send a signal)
- stop (kill with SIGTERM)
- write (to its stdin)
- close (its stdin)
A process name starts with a 'p' and accepts a shell pipeline as the
command line. Environment variables can be set directly in the command
line.
A process will create a macro with its PID, and its stdout and stderr
are redirected to files in a dedicated directory.
