[issue38251] urllib.request memory leak / overflow
New submission from Ofer Sadan :
running `urllib.request.urlopen` multiple times causes the memory usage to
increase with each run, even after calling `close()` on the request or using
`del` on the result
To recreate this problem, run code:
import urllib.request
def ip():
r = urllib.request.urlopen('https://api.ipify.org')
b = r.read()
r.close()
print(len(b))
return b
for i in range(1000):
result = ip()
del result
Even though `len(b)` has a maximum value of 15 (for this url at least), the
memory increases with each run by 200KB - 1MB

Ofer Sadan added the comment: Just to note: I'm using Python 3.7.4 on Windows 10 (64bit), the issue exists on both the 32bit/64bit python versions I could test on. -- ___ Python tracker <https://bugs.python.org/issue38251> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Ofer Sadan added the comment: I can confirm that testing with http instead of https this problem doesn't exist, on 3.7.4. Are the issues closed because this problem is fixed in the upcoming 3.7.5, or 3.8.0? -- ___ Python tracker <https://bugs.python.org/issue38251> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
