`Parser` is used by many plugins and custom hooks. `OptionGroup` is
exposed by the `parser.addgroup` API.
The constructors of both are marked private, they are not meant to be
constructed directly.
Given a `RecursionError` traceback, the `Traceback.recursionindex()`
method returns the index of the frame which started the recursion
(repeated set of frames). To do so it attempts to check whether two
frames are equivalent. Just checking the function/line is not enough
because the recursion variable(s) might differ (e.g. imagine the numeric
value in a recursive factorial implementation). So it also compares the
`f_locals` (local variables) of each frame for equivalence.
For some reason, the locals comparison is wrapped in an `eval` whose
purpose is to evaluate the comparison in one of the compared frame's
context (locals + globals in scope). However, I can not think of any way
in which the global scope could affect the evaluation. It would have an
affect when the locals are bound but that's already done. So this seems
unnecessary - remove it.

pytest uses a root temp directory named `/tmp/pytest-of-<username>`. The
name is predictable, and the directory might already exists from a
previous run, so that's allowed.
This makes it possible for my_user to pre-create
`/tmp/pytest-of-another_user`, thus giving my_user control of
another_user's tempdir.
Prevent this scenario by adding a couple of safety checks. I believe
they are sufficient.
Testing the first check requires changing the owner, which requires
root permissions, so can't be unit-tested easily, but I checked it
manually.
(Written for a Unix system, but might be applicable to Windows as well).
pytest creates a root temporary directory under /tmp, named
`pytest-of-<username>`, and creates tmp_path's and other under it.
/tmp is shared between all users of the system.
This root temporary directory was created with 0o777&~umask permissions,
which usually becomes 0o755, meaning any user in the system could list
and read the files, which is undesirable.
Use 0o700 permissions instead. Also for subdirectories, because the root
dir is adjustable.
Calling pkg_resources.fixup_namespace_packages() is only needed for packages
that use pkg_resources.declare_namespace() and hence they already imported
pkg_resources. When pkg_resources is not imported, we don't need to use it.
This avoids an unneeded runtime dependency on setuptools.
The code is tested by test_syspath_prepend_with_namespace_packages,
behavior should remain unchanged, hence no new test was added.
When people drop pkg_resources from sys.modules, they are on their own.
If someone has a actual use case making this valid to support,
they can come in and provide a test, a reference and a fix.
This type is most prominent in `pytest.raises` and we should allow to
refer to it by a public name.
The type is not in a perfectly "exposable" state. In particular:
- The `traceback` property with type `Traceback` which is derived from
the `py.code` API and exposes a bunch more types transitively. This
stuff is *not* exported and probably won't be.
- The `getrepr` method which probably should be private.
But they're already used in the wild so no point in just hiding them
now.
The __init__ API is hidden -- the public API for this are the `from_*`
classmethods.
The prefixes make the API Reference docs (for e.g. `pytest.raises`,
`pytest.fixture`) uglier.
Being under `_pytest` is sufficient from a privacy perspective, so let's
drop them.
* Fix test_strict_and_skip
The `--strict` argument was removed in #2552, but the removal wasn't
actually correct - see #1472.
* Fix argument handling in pytest.mark.skip
See #8384
* Raise from None
* Fix test name
* retry writing pytest-of dir when invalid chars are in directory name
* add unit tests for getbasetemp() and changelog
* patch _basetemp & _given_basetemp for testing basetemp()
* Tweak changelog for #8317, tidy up comments
Similarly to #7143, at work we have a project with a custom pytest.Class
subclass, adding an additional argument to the constructor.
All from_parent implementations in pytest accept and forward *kw, except
Class (before this change) and DoctestItem - since I'm not familiar with
doctest support, I've left the latter as-is.
* Type annotation polishing for symbols around Pytester.run
Hopefully these will help document readers understand pertinent methods
and constants better.
Following up #8294
* Use NOTSET instead of object
SetupState maintains its own state, so it can store the exception
itself, instead of using the node's store, which is better avoided when
possible.
This also reduces the lifetime of the reference-cycle-inducing exception
objects which is never a bad thing.
The assertion ensures that when `addfinalizer(finalizer, node)` is
called, the node is in the stack. This then would ensure that the
finalization is actually properly executed properly during the node's
teardown. Anything else indicates something is wrong.
Previous commits fixed all of the tests which previously failed this, so
can be reenabeld now.
When the stack is empty, the finalizers which are supposed to be
attached to nodes in the stack really ought to be empty as well. So the
code here is dead. If this doesn't happen, the assert will trigger.
It seems the code that would not install pytest's faulthandler support
if it was already enabled is not really needed at all, and even detrimental
when using `python -X dev -m pytest` to run Python in "dev" mode.
Also simplified the plugin by removing the hook class, now the hooks
will always be active so there's no need to delay the hook definitions anymore.
Fix#8258
The Twisted Logger will return an invalid file descriptor since it is
not backed by an FD. So, let's also forward this to the same code path
as with `pytest-xdist`.
as PyObjMixin is always supposed to be mixed in the mro
before nodes.Node the behavior doesn't change,
but all the typing information carry over to help mypy.
extracted from #8037
It is not very clear why this code exists -- we are not running any
unittest or nose code during collection, and really these frameworks
don't have the concept of collection at all, and just raising these
exceptions at e.g. the module level would cause an error. So unless I'm
missing something, I don't think anyone is using this.
Deprecate it so we can eventually clear up this code and keep unittest
more tightly restricted to its plugin.
When `pytest.skip()` is called inside a test function, the skip location
should be reported as the line that made the call, however when
`pytest.skip()` is called by the `pytest.mark.skip` and similar
mechanisms, the location should be reported at the item's location,
because the exact location is some irrelevant internal code.
Currently the item-location case is implemented by the caller setting a
boolean key on the item's store and the `skipping` plugin checking it
and fixing up the location if needed. This is really roundabout IMO and
breaks encapsulation.
Instead, allow the caller to specify directly on the skip exception
whether to use the item's location or not. For now, this is entirely
private.
When line_index was a large negative number, get_source failed
on `source.lines[line_index]`.
Use the same dummy Source as with a large positive line_index.

The type cannot be constructed directly, but is exported for use in type
annotations, since it is reachable through existing public API.
This also documents `from_call` as public, because at least
pytest-forked uses it, so we must treat it as public already anyway.
Add a new hook , `pytest_markeval_namespace` which should return a dictionary.
This dictionary will be used to augment the "global" variables available to evaluate skipif/xfail/xpass markers.
Pseudo example
``conftest.py``:
.. code-block:: python
def pytest_markeval_namespace():
return {"color": "red"}
``test_func.py``:
.. code-block:: python
@pytest.mark.skipif("color == 'blue'", reason="Color is not red")
def test_func():
assert False
On Windows, os.path.samefile returns false for paths mounted in UNC paths which
point to the same location.
I couldn't reproduce the actual case reported, but looking at the code it seems
this commit should fix the issue.
Fix#7678Fix#8076
Explanation: The default handling of these lifetimes is done in
`tmpdir.TempPathFactory.getbasetemp`, which passes `keep=3` to
`pathlib.make_numbered_dir_with_cleanup`.

* Prefix contextmanagers with module name in doc examples
* Import pytest explicitly for doctests

Python 3.7 changes the pyc format by adding a flags byte. Even though it
is not necessary for us to match it, it is nice to be able to read pyc
files we emit for debugging the rewriter.
Update our custom pyc files to use that format. We write flags==0
meaning we still use the mtime+size format rather the newer hash format.
In order to allow users to type annotate fixtures they request, the
types need to be imported from the `pytest` namespace. They are/were
always available to import from the `_pytest` namespace, but that is
not guaranteed to be stable.
These types are only exported for the purpose of typing. Specifically,
the following are *not* public:
- Construction (`__init__`)
- Subclassing
- staticmethods and classmethods
We try to combat them being used anyway by:
- Marking the classes as `@final` when possible (already done).
- Not documenting private stuff in the API Reference.
- Using `_`-prefixed names or marking as `:meta private:` for private
stuff.
- Adding a keyword-only `_ispytest=False` to private constructors,
warning if False, and changing pytest itself to pass True. In the
future it will (hopefully) become a hard error.
Hopefully that will be enough.
An upcoming commit wants to import from `_pytest.pytester` in the public
`pytest` module. This means that `_pytest.pytester` would start to get
imported during import time, which it hasn't up to now -- it was
imported by the plugin loader (if requested). When a plugin is loaded,
it is subjected to assertion rewriting, but only if the module isn't
imported yet, it issues a warning "Module already imported so cannot be
rewritten" and skips the rewriting. So we'd end up with the pytester
plugin not being rewritten, but it wants to be.
Absent better ideas, the solution here is to split the pytester
assertions to their own plugin (which will always only be imported by
the plugin loader) and exclude pytester itself from plugin rewriting.
When --doctest-modules is used, an `__init__.py` file is not a `Package`
but a `DoctestModule`, but some collection code assumed that
`__init__.py` implies a `Package`. That code caused only a single test
to be collected in the scenario in the subject.
Tighten up this check to explicitly check for `Package`. There are
better solutions, but for another time.
Report & test by Nick Gates <nickgatzgates@gmail.com>.
We want to export `pytest.MonkeyPatch` for the purpose of
type-annotating the `monkeypatch` fixture. For other fixtures we export
in this way, we also make direct construction of them (e.g.
`MonkeyPatch()`) private. But unlike the others, `MonkeyPatch` is also
widely used directly already, mostly because the `monkeypatch` fixture
only works in `function` scope (issue #363), but also in other cases. So
making it private will be annoying and we don't offer a decent
replacement yet.
So, let's just make direct construction public & documented.
