Proc::Guard - process runner with RAII pattern
use Test::TCP qw/empty_port wait_port/;
use File::Which qw/which/;
use Proc::Guard;
my $port = empty_port();
my $proc = proc_guard(scalar(which('memcached')), '-p', $port);
wait_port($port);
# your code here
# --------------
# or, use perl code
my $proc = proc_guard(sub {
... # run this code in child process
});
...
Proc::Guard runs process, and destroys it when the perl script exits.
This is useful for testing code working with server process.
- proc_guard(@cmdline|\&code)
- This is shorthand for:
Proc::Guard->new(
command => \@cmdline,
);
or
Proc::Guard->new(
code => \&code,
);
- my $proc = Proc::Guard->new(%args);
- Create and run a process. The process is terminated when the returned
object is being DESTROYed.
- command
-
Proc::Guard->new(command => '/path/to/memcached');
# or
Proc::Guard->new(command => ['/path/to/memcached', '-p', '11211']);
The command line.
- code
-
Proc::Guard->new(code => sub { ... });
'code' or 'command' is required.
- auto_start
-
Proc::Guard->new(auto_start => 0);
Start child process automatically or not(default: 1).
- pid
- Returns process id (or undef if not running).
- start
- Starts process.
- stop
- Stops process.
- $Proc::Guard::EXIT_STATUS
- The last exit status code by
"$proc->stop". If
"waitpid" failed with an error, this
will be set to "undef".
