Loco program runner core
========================

We use this python-c library to run program in a sandbox-like environment.
With it, we can accurately known the resource using of the program and 
limit its resource using including system-call interrupt.

Usage
-----

For run a program without tracing:

    runcfg = {
        'args':['./m'],
        'fd_in':fin.fileno(),
        'fd_out':ftemp.fileno(),
        'timelimit':1000, #in MS
        'memorylimit':20000, #in KB
    }
    
    rst = lorun.run(runcfg)

For check one output:

    ftemp = file('temp.out')
    fout = file(out_path)
    crst = lorun.check(fout.fileno(), ftemp.fileno())


trace
-----

You can set runcfg['trace'] to True to ensure runner's security.

Here is a simple usage:

```
runcfg['trace'] = True
runcfg['calls'] = [1, 2, 3, 4] # system calls that could be used by testing programs
runcfg['files'] = {'/etc/ld.so.cache': 0} # open flag permitted (value is the flags of open)
```
