flake8: enable F821 check
Summary:
This check is useful and detects real errors (ex. fbconduit). Unfortunately
`arc lint` will run it with both py2 and py3 so a lot of py2 builtins will
still be warned.
I didn't find a clean way to disable py3 check. So this diff tries to fix them.
For `xrange`, the change was done by a script:
```
import sys
import redbaron
headertypes = {'comment', 'endl', 'from_import', 'import', 'string',
'assignment', 'atomtrailers'}
xrangefix = '''try:
xrange(0)
except NameError:
xrange = range
'''
def isxrange(x):
try:
return x[0].value == 'xrange'
except Exception:
return False
def main(argv):
for i, path in enumerate(argv):
print('(%d/%d) scanning %s' % (i + 1, len(argv), path))
content = open(path).read()
try:
red = redbaron.RedBaron(content)
except Exception:
print(' warning: failed to parse')
continue
hasxrange = red.find('atomtrailersnode', value=isxrange)
hasxrangefix = 'xrange = range' in content
if hasxrangefix or not hasxrange:
print(' no need to change')
continue
# find a place to insert the compatibility statement
changed = False
for node in red:
if node.type in headertypes:
continue
# node.insert_before is an easier API, but it has bugs changing
# other "finally" and "except" positions. So do the insert
# manually.
# # node.insert_before(xrangefix)
line = node.absolute_bounding_box.top_left.line - 1
lines = content.splitlines(1)
content = ''.join(lines[:line]) + xrangefix + ''.join(lines[line:])
changed = True
break
if changed:
# "content" is faster than "red.dumps()"
open(path, 'w').write(content)
print(' updated')
if __name__ == "__main__":
sys.exit(main(sys.argv[1:]))
```
For other py2 builtins that do not have a py3 equivalent, some `# noqa`
were added as a workaround for now.
