# They both result in the LOAD_CONST bytecode, one a tuple one a

# a linear scan of a tuple; but if the tuple is small, it can often

# For releases prior to 2.14.2, this needs to be a one-line, quoted string. After that,
# a multi-line string.
# - Make zope.cachedescriptors.property.Lazy look like a property;
# fixes pylint thinking it is a method.
# - Run in Pure Python mode (ignore C extensions that respect this);
# fixes some issues with zope.interface, like IFoo.providedby(ob)

# Ending on a quoted string
# breaks pylint 2.14.5 (it strips the trailing quote. This is

# The parens around it fix the issue.
[MESSAGES CONTROL]
# Disable the message, report, category or checker with the given id(s). You
# can either give multiple identifier separated by comma (,) or put this option
# multiple time (only on the command line, not in the configuration file where
# it should appear only once).
# NOTE: comments must go ABOVE the statement. In Python 2, mixing in
# comments disables all directives that follow, while in Python 3, putting
# comments at the end of the line does the same thing (though Py3 supports
# mixing)
# too-many-positional-arguments: we inherit most of these and can't do anything about them.
# invalid-name, ; We get lots of these, especially in scripts. should fix many of them
# protected-access, ; We have many cases of this; legit ones need to be examinid and commented, then this removed
# no-self-use, ; common in superclasses with extension points
# too-few-public-methods, ; Exception and marker classes get tagged with this
# exec-used, ; should tag individual instances with this, there are some but not too many
# global-statement, ; should tag individual instances
# multiple-statements, ; "from gevent import monkey; monkey.patch_all()"
# locally-disabled, ; yes, we know we're doing this. don't replace one warning with another
# cyclic-import, ; most of these are deferred imports
# too-many-arguments, ; these are almost always because that's what the stdlib does
# redefined-builtin, ; likewise: these tend to be keyword arguments like len= in the stdlib
# undefined-all-variable, ; XXX: This crashes with pylint 1.5.4 on Travis (but not locally on Py2/3
# ; or landscape.io on Py3). The file causing the problem is unclear. UPDATE: identified and disabled
# that file.
# see https://github.com/PyCQA/pylint/issues/846
# useless-suppression: the only way to avoid repeating it for specific statements everywhere that we
# do Py2/Py3 stuff is to put it here. Sadly this means that we might get better but not realize it.
# duplicate-code: Yeah, the compatibility ssl modules are much the same
# In pylint 1.8.0, inconsistent-return-statements are created for the wrong reasons.
# This code raises it, even though there is only one return (the implicit ``return None`` is presumably
# what triggers it):
# def foo():
# if baz:
# return 1
# In Pylint 2dev1, needed for Python 3.7, we get spurious "useless return" errors:
# @property
# def foo(self):
# return None # generates useless-return
# Pylint 2.4 adds import-outside-toplevel. But we do that a lot to defer imports because of patching.
# Pylint 2.4 adds self-assigning-variable. But we do *that* to avoid unused-import when we
# "export" the variable and dont have a __all__.
# Pylint 2.6+ adds some python-3-only things that dont apply: raise-missing-from, super-with-arguments, consider-using-f-string, redundant-u-string-prefix
# cyclic import is added because it pylint is spuriously detecting that
# consider-using-assignment-expr wants you to transform things like:
# foo = get_foo()
# if foo: ...
#
# Into ``if (foo := get_foo()):``
# But there are a *lot* of those. Trust people to do the right, most
# readable, thing
#
# XXX: unclear on the docstring warnings, missing-type-doc, missing-param-doc,
# differing-param-doc, differing-type-doc (are the last two replacements for the first two?)
#
# They should be addressed, in general they are a good thing, but sometimes they are
# unnecessary.
