Would it be possible to add to std.process.Config POSIX specific
callback which would be called after fork()?
It is currently main blocker in switching dpaste-be from handmade
process handling module to std.process.
It could look something like this.
struct Config {
// current fields
void delegate() posixCallback;
}
// ...
int i = fork();
if (i > 0)
{
//...
if (config.posixCallback !is null)
config.posixCallback();
//...
}
Such construct would allow for various child process
manipulation, for instance
dropping root privileges or setting limits via setrmlimit.
Example:
config.posixCallback = {
setguid(ourGUID);
setgroups(ourGROUPS);
setuid(ourUID);
setrmlimit(NFORK, 123);
};
AFAIK we already have Windows specific flag related to spawning
console for GUI apps.
I can make pull request ASAP when I get reasonable name for field.
Lars? ;)
