* gh-94315: Check for DAC override capability (GH-94316)Christian Heimes2022-06-271-2/+1
| | | | | ``os.geteuid() == 0`` is not a reliable check whether the current user has the capability to bypass permission checks. Tests now probe for DAC override.
* gh-84461: Skip test_unwritable_directory again on Emscripten (GH-94007)Christian Heimes2022-06-191-0/+1
| | | GH-93992 removed geteuid() and enabled the test again on Emscripten.

* gh-90473: Make chmod a dummy on WASI, skip chmod tests (GH-93534)Christian Heimes2022-06-061-0/+3
| | | WASI does not have the ``chmod(2)`` syscall yet.
* gh-90473: Skip and document more failing tests on WASI (GH-93436)Christian Heimes2022-06-021-2/+6
| | | | | | | - Mark more ``umask()`` cases - ``dup()`` is not supported - ``/dev/null`` is not available - document missing features - mark more modules as not available
* bpo-40280: Detect missing threading on WASM platforms (GH-32352)Christian Heimes2022-04-071-0/+1

* bpo-40280: Skip socket, fork, subprocess tests on Emscripten (GH-31986)Christian Heimes2022-03-221-3/+13
| | | | | | | | | | | - Add requires_fork and requires_subprocess to more tests - Skip extension import tests if dlopen is not available - Don't assume that _testcapi is a shared extension - Skip a lot of socket tests that don't work on Emscripten - Skip mmap tests, mmap emulation is incomplete - venv does not work yet - Cannot get libc from executable The "entire" test suite is now passing on Emscripten with EMSDK from git head (91 suites are skipped).

* bpo-45020: Freeze some of the modules imported during startup. (gh-28335)Eric Snow2021-09-151-3/+5
| | | | | | | Doing this provides significant performance gains for runtime startup (~15% with all the imported modules frozen). We don't yet freeze all the imported modules because there are a few hiccups in the build systems we need to sort out first. (See bpo-45186 and bpo-45188.) Note that in PR GH-28320 we added a command-line flag (-X frozen_modules=[on|off]) that allows users to opt out of (or into) using frozen modules. The default is still "off" but we will change it to "on" as soon as we can do it in a way that does not cause contributors pain. https://bugs.python.org/issue45020

* bpo-39336: Allow packages to not let their child modules be set on them (#18006)Dino Viehland2020-01-233-0/+26
| | | | | * bpo-39336: Allow setattr to fail on modules which aren't assignable When attaching a child module to a package if the object in sys.modules raises an AttributeError (e.g. because it is immutable) it causes the whole import to fail. This now allows immutable packages to exist and an ImportWarning is reported and the AttributeError exception is ignored.
* bpo-37409: fix relative import with no parent (#14956)Ben Lewis2019-09-111-0/+5
| | | | | | | | | | | | | Relative imports use resolve_name to get the absolute target name, which first seeks the current module's absolute package name from the globals: If __package__ (and __spec__.parent) are missing then import uses __name__, truncating the last segment if the module is a submodule rather than a package __init__.py (which it guesses from whether __path__ is defined). The __name__ attempt should fail if there is no parent package (top level modules), if __name__ is '__main__' (-m entry points), or both (scripts). That is, if both __name__ has no subcomponents and the module does not seem to be a package __init__ module then import should fail.

* bpo-33053: -m now adds *starting* directory to sys.path (GH-6231)Nick Coghlan2018-03-251-4/+7
| | | | | | | | | | | | Historically, -m added the empty string as sys.path zero, meaning it resolved imports against the current working directory, the same way -c and the interactive prompt do. This changes the sys.path initialisation to add the *starting* working directory as sys.path[0] instead, such that changes to the working directory while the program is running will have no effect on imports when using the -m switch.

* closes bpo-31650: PEP 552 (Deterministic pycs) implementation (#4575)Benjamin Peterson2017-12-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Python now supports checking bytecode cache up-to-dateness with a hash of the source contents rather than volatile source metadata. See the PEP for details. While a fairly straightforward idea, quite a lot of code had to be modified due to the pervasiveness of pyc implementation details in the codebase. Changes in this commit include: - The core changes to importlib to understand how to read, validate, and regenerate hash-based pycs. - Support for generating hash-based pycs in py_compile and compileall. - Modifications to our siphash implementation to support passing a custom key. We then expose it to importlib through _imp. - Updates to all places in the interpreter, standard library, and tests that manually generate or parse pyc files to grok the new format. - Support in the interpreter command line code for long options like --check-hash-based-pycs. - Tests and documentation for all of the above.
