Lennart Poettering a6149b93af process-util: trivial optimization 2015-08-31 13:20:43 +02:00
Lennart Poettering 03c55bc0b9 process: an empty environment block should be returned as such 
An empty env block is completely valid, hence return it as such, and
don't turn it into an error.

Lennart Poettering a644184a17 process: return ESRCH when a PID is not valid anymore 
so far, when we read something from /proc/$PID we would pass on the
ENOENT from the kernel as error, if the process was missing. With this
change we systematically convert this to ESRCH, which is the more
appropriate error code, and what all the other glibc/syscalls like
kill() use.

All code that calls these functions should be fine with this change. In
fact, one invocation of get_process_exe() in bus-creds.c already assumed
ESRCH would be returned if a process is missing, and this assumption is
now validated after the change.

Kay Sievers a095315b3c build-sys: split internal basic/ library from shared/ 
basic/      can be used by everything
            cannot use anything outside of basic/

libsystemd/ can use basic/
            cannot use shared/

shared/     can use libsystemd/
