Richard Purdie e1e6066934 bitbake: bitbake-server/worker: Hide os.fork() deprecation warning

We're fairly careful in bitbake about how we handle fork() calls and believe our code
to be safe. The upstream deprecation warning is problematic as it can appear in log
output as a WARNING, breaking tests. It also tends to alarm users.

Hide the warning for now to avoids the test failures.

(Bitbake rev: c636bd629896f56e5f3d4030da3d1f130590afc6)

Replace standard fds with our own

with open('/dev/null', 'r') as si: os.dup2(si.fileno(), sys.stdin.fileno())

with open(logfile, 'a+') as so: os.dup2(so.fileno(), sys.stdout.fileno()) os.dup2(so.fileno(), sys.stderr.fileno())

Have stdout and stderr be the same so log output matches chronologically

and there aren't two seperate buffers

sys.stderr = sys.stdout

logger = logging.getLogger("BitBake")

Ensure logging messages get sent to the UI as events

handler = bb.event.LogHandler() logger.addHandler(handler)

bb.server.process.execServer(lockfd, readypipeinfd, lockname, sockname, timeout, xmlrpcinterface, profile)
