# HG changeset patch# User Anton Shestakov <av6@dwimlabs.net># Date 1591442367 -28800# Node ID a4438263b228dd3e2983d59095c6180b1411f0e8# Parent 83e41b73d115e3717943c2e5a83d36d05670384ctests: skip pyflakes for mercurial/thirdparty/The current version of pyflakes (2.2.0) correctly detects one issue: mercurial/thirdparty/selectors2.py:335:40 '...'.format(...) has unused arguments at position(s): 1But we're not interested in fixing lint errors in third-party code, so we needto exclude at least selectors2.py. And in the discussion for this patch it wasdecided to just skip the entire thirdparty directory.Differential Revision: https://phab.mercurial-scm.org/D8619diff -r 83e41b73d115 -r a4438263b228 tests/test-check-pyflakes.t--- a/tests/test-check-pyflakes.tTue Jun 09 17:13:26 2020 -0400+++ b/tests/test-check-pyflakes.tSat Jun 06 19:19:27 2020 +0800@@ -16,9 +16,7 @@ $ testrepohg locate 'set:**.py or grep("^#!.*python")' \ > -X hgext/fsmonitor/pywatchman \ > -X mercurial/pycompat.py -X contrib/python-zstandard \- > -X mercurial/thirdparty/cbor \- > -X mercurial/thirdparty/concurrent \- > -X mercurial/thirdparty/zope \+ > -X mercurial/thirdparty \ > 2>/dev/null \ > | xargs $PYTHON -m pyflakes 2>/dev/null | "$TESTDIR/filterpyflakes.py" contrib/perf.py:*:* undefined name 'xrange' (glob) (?)
