[issue13131] FD leak in urllib2
New submission from Valery Khamenya : Explanation from dablitz's comment at https://bugs.pypy.org/issue867 : urllib2 in the stdlib leaks fd's if an exception is raised while opening a connection. The issue occurs due to a socket being opened then an exception being raised before an object with the socket is returned, leaving no way to explicitly close the object. On cpython this would not be an issue as the object would lose all references almost immediately however it lingers around with a proper GC causing FD's to build up if the same condition happens repeatedly (eg a loop/web crawling) The file enclosed is a script to generate the leakage, to run invok it as follows leak.py pypy should start leaking FD's and can be see in /proc//fd Related issues: http://bugs.python.org/issue3066 http://bugs.python.org/issue1208304 http://bugs.python.org/issue1601399 -- components: IO, Library (Lib) files: leak.py messages: 145166 nosy: Valery.Khamenya priority: normal severity: normal status: open title: FD leak in urllib2 type: resource usage versions: Python 2.7 Added file: http://bugs.python.org/file23344/leak.py ___ Python tracker <http://bugs.python.org/issue13131> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue12955] urllib2.build_opener().open() is not friendly to "with ... as:"
Valery Khamenya added the comment:
Terry, Senthil, thanks, for replying to this ticket. OK, to the question:
1. @Terry, here is the full example as for CPython 2.7 I am talking about and
the output:
#
from urllib2 import Request, build_opener
request = Request('http://example.com')
with build_opener().open(request) as f:
txt = f.read()
print '%d characters fetched' % len(txt)
Traceback (most recent call last):
File "", line 1, in
AttributeError: addinfourl instance has no attribute '__exit__'
2. @Senthil, regarding the statement being a feature. I assume, that to open a
connection, to read from a connection and to close it -- are the fundamental
functions for what urllib2 was in particular created for. I was looking in docs
for some hints of "canonical" way of doing this using urllib2.opener. After I
have failed to find any guidance in docs, I've created this ticket. That is, I
assume that no new feature is needed, but just a documented 5-lines example
about a typical way of doing the above operations, especially *closing* the
connection.
regards,
Valery

[issue10351] to introduce autocompletion for keys in dictionaries (patch attached)
New submission from Valery Khamenya :
1. The patch introduces autocompletion for keys in dictionaries (patch attached)
2. The patched rlcompleter as such works OK for unicode dictionary keys as
well. All tests pass OK. HOWEVER, readline's completion mechanism seem to be
confused with unicode strings -- see comments to Completer.dict_key_matches().
So, perhaps, one day some changes should be applied to readline code too.
3. rlcompleter.py has no tests in trunk -- I spawn a separate issue for it.
Meanwhile I took test_rlcompleter.py from 2.7 and extended it.
4. The following usual lines in .pythonstartup:
import readline
import rlcompleter
readline.parse_and_bind('tab: complete')
readline.parse_and_bind('Control-Space: complete')
should be extended by this one:
readline.set_completer_delims(re.compile(r'[\'"\\[]').sub('',
readline.get_completer_delims()))

Some thoughts about solution: maybe it's possible to pass only filename and python will open (and close) file itself?
