Hey everyone,
I modified the webpy reloader to be less kind in general -- syntax
errors, for instance, will just kill the process -- but it generally
gets rid of issues with reloader not picking up changes. It only works
in linux, by waking up every second to check for changes. If anyone's
interested, here's the code and how to use it:
app = web.application(urls, globals() # as usual
## Reloader
import sys, os, signal, pprint, types
class PeriodicReloader(object):
def __init__(self, interval=1):
self.interval = interval
self.mtimes = {}
self.sig_setup()
def sig_setup(self):
signal.signal(signal.SIGALRM, self.check)
signal.alarm(self.interval)
def check(self, signum, frame):
for mod in sys.modules.values():
if not isinstance(mod, types.ModuleType):
continue
path = getattr(mod, '__file__', None)
if not path:
continue
mtime = os.stat(mod.__file__).st_mtime
if mod.__file__.endswith('.pyc') and
os.path.exists(mod.__file__[:-1]):
mtime = max(os.stat(mod.__file__[:-1]).st_mtime,
mtime)
if mod not in self.mtimes:
self.mtimes[mod] = mtime
elif self.mtimes[mod] < mtime:
web.debug("Reloading app due to module change")
os.execv(sys.executable, [sys.executable] + sys.argv)
self.sig_setup()
### Go ###
if __name__ == '__main__':
if web.config.debug:
PeriodicReloader()
app.run()
