python function call subtleties about semgrep HOT 3 CLOSED

Is it normal there is extra parenthesis inside $S.bind? (("", ...))

from semgrep.

Yes, not a typo -- you call .bind with a tuple

from semgrep.

I can't reproduce on your test example.
If I do this pattern:
$S = socket.socket(...)
...
$S.bind()

$ /home/pad/github/sgrep/_build/default/bin/main_sgrep.exe -f tests/python/misc_tuple.sgrep tests/python/
/home/pad/github/sgrep/tests/python/misc_tuple.py:1
easy_s = socket.socket(doesnt, matter)
easy_s.bind()

it finds it. But I put back your pattern:
$S = socket.socket(...)
...
$S.bind(("", ...))

$ /home/pad/github/sgrep/_build/default/bin/main_sgrep.exe -f tests/python/misc_tuple.sgrep tests/python/
then no match (as expected).

from semgrep.
