Installation:
|
|
|
|
If you want to run the compiler inside a virtual machine for more security,
|
|
these scripts are designed to work with qemu 0.11.1. This is required in
|
|
order to use PBot's trigger.
|
|
|
|
In addition, you can use the provided 'cc' script to use your local compiler tools
|
|
without installing qemu. No PBot installation or configuration is required in this case.
|
|
|
|
To use the local non-vm 'cc' script, you will need to have gcc, gdb and astyle installed locally.
|
|
|
|
Be aware that you need to single-quote or escape the code if you use the local 'cc' within a shell,
|
|
e.g.: ./cc $'char s[] = "hello, world"; puts(s); if(s[0] == \'h\') puts("true");'
|
|
|
|
WARNING: Using the local 'cc' script outside of the virtual machine will not use qemu at all;
|
|
it will affect local system -- compile "safe" code!
|
|
|
|
Virtual machine installation:
|
|
|
|
You will need to download qemu and set up a virtual machine containing a system
|
|
with a compiler and, optionally, sensible ulimits/fork-preventation/other security.
|
|
|
|
1) copy compiler_vm_server.pl and compiler_watchdog.pl to the virtual machine.
|
|
2) then start up the compiler_vm_server.pl script inside the virtual machine
|
|
3) then connect to qemu's monitor and issue the 'savevm 1' command to save the virtual state
|
|
(After compiles, this state will be loaded via 'loadvm 1' to reset everything within the machine
|
|
for a clean and working environment for subsequent compiles.)
|
|
|
|
Now the virtual machine state 1 is saved in a state where it is listening for incoming code. You can
|
|
go ahead and quit qemu without shutting down the guest operating sytem.
|
|
|
|
Starting the virtual machine for PBot:
|
|
|
|
Now that the virtual machine is configured and saved, you may launch the local server to listen for
|
|
code from PBot to send to the virtual machine's server. To do so, run the compiler_server.pl script.
|
|
|
|
Dependencies:
|
|
|
|
gcc (tested with 4.4.4)
|
|
gdb (tested with 7.2)
|
|
astyle (tested with 1.24 -- not working with astyle 2.0)
|
|
|
|
Files:
|
|
|
|
(Read within each file for configuration instructions.)
|
|
|
|
- cc: Allows you to use the compiler locally with or without qemu installed.
|
|
Can be used within virtual machine for testing.
|
|
Requires only compiler_vm_client.pl, compiler_vm_server.pl and compiler_watchdog.pl.
|
|
Must have gcc, gdb and astyle installed locally if not used within virtual machine.
|
|
WARNING: If not used within virtual machine will not use qemu at all and will
|
|
affect local system -- compile "safe" code!
|
|
|
|
- compiler_client.pl: Main entry point for compiling snippets. Sends over TCP to
|
|
compiler_server.pl. This file can be run be run from the
|
|
client machine or anywhere.
|
|
|
|
- compiler_server.pl: Responsible for setting up a TCP server to listen for
|
|
incoming compile requests; and launching and resetting
|
|
the virtual machine. Sends to compiler_vm_client.pl.
|
|
Run this file on the server hosting the virtual machine.
|
|
|
|
- compiler_vm_client.pl: Responsible for sending snippets to the virtual
|
|
machine. Also expands/translates and formats
|
|
snippets into compilable code (with main function and
|
|
headers), and handles "interactive-editing".
|
|
Sends over TCP to qemu serial port, waits for result,
|
|
then sends result back caller (compiler_server.pl).
|
|
Run this file on the server hosting the virtual machine.
|
|
|
|
- compiler_vm_server.pl: Runs on the system inside the virtual machine.
|
|
This script listens for incoming code snippets over
|
|
the virtual machine's serial port.
|
|
Calls compiler_watchdog.pl to monitor its exit signal
|
|
or exit status, then returns result back over serial
|
|
port (to compiler_vm_client.pl).
|
|
|
|
- compiler_watchdog.pl: Runs a program and watches its exit signals/status.
|
|
Run within the virtual machine.
|
|
|
|
*** The following files are just auxiliary tools to start/connect to qemu, provided
|
|
for convenience only. Perhaps they will be useful during installation/testing:
|
|
|
|
- monitor: Connects to qemu monitor (internal console) over TCP.
|
|
|
|
- serial: Connects to qemu serial port over TCP.
|
|
|
|
- runqemu: Launches qemu with a visible window, but without networking support.
|
|
|
|
- runeqmu.net: Launches qemu with a visible window, and with networking support.
|
|
You may load a state previously saved with runqemu and reboot it
|
|
or otherwise reload its networking configuration to gain networking.
