how do you spell strace on akaros? cat
The way we were doing tracing, via the monitor command, was just plain inconvenient. This one is easy. Cat /proc/pid/strace. That's it. Or more or dd, or whatever. I think this can let us shrink the other bits of the kernel that are there for process trace. TODO: manage inheritance. This is, also, far lower overhead than strace, even better than my last time out at this problem as seen in http://5e.iwp9.org/slides/ratracetalk.pdf which was about 100x fewer system calls than strace on linux. 2016/01/25 17:34:06 Pull is The following changes since commit 915eac00a7e0f578f9e921af2b205b6efa3739b5: Slices: A growable list of pointers.
