Following some discussion on IRC with @GrahamDumpleton this patch only
close stdios if -R isn't specified. It also let others fds open and
don't try to close them.
This should fix logging around and behave like other daemons. It should
also close#309.
Enable inheritance for stdio file descriptors in daemon mode. It allows
you in daemon mode to redirect the output to a file if needed.
By default in daemon mode gunicorn will close all file handle except if
you pass the "-R" options. In this cases STDIO will be preserved.
fix#309
Closing sockets when stopping the arbiter was also closing unix sockets
if any because they aren't attached to a specific process. So remove it
and let the vm close them if needed. This change fix the reload of the
binary.
fix#476
You can now pass a list of file descriptors to Gunicorn that won't be
closed when it starts. Allows someone to pass any stream to gunicorn or
set some redirection.
Instead of faking STDIN/STDERR to a fake object that we close on reopen,
simply redirect them to a file and reopen this one when need.
Should fix most of the issues on #309
The Arbiter is smart about getting the CWD; first it checks the CWD
environment (which doesn't resolve symlinks), then it falls back to the
python os.getcwd() (which does resolve symlinks). However, the Arbiter
is the only place that does this, which will then do the right thing
when we reexec. However, when reloading the Arbiter, it won't pick up
changes if the symlink has changed.
By changing the *app.py entry points to also use the same method for
determining the CWD, we'll insert a symlink path into the first location
in sys.path. Then our reloaded app will correctly pull in any new
changes.
