2024-04-02add documentation regarding resource management of AtLocationsHelmut Grohne
2024-04-02fix logic error in AtLocation.statHelmut Grohne
Fixes: 1c265b6e11c3 ("add os.stat wrapper AtLocation.stat")
2024-03-24AtLocation.mkdir: support optional arguments from pathlibHelmut Grohne
2024-03-22add convenience functions for stat to AtLocationLikeHelmut Grohne
These are the is_* family and exists all from pathlib.Path.
2024-03-22add os.stat wrapper AtLocation.statHelmut Grohne
2024-03-16add an asyncio variant of run_in_forkHelmut Grohne
2024-03-14rename AtLocation.symlink to symlink_toHelmut Grohne
This mirrors what was done for pathlib.Path to avoid confusion about argument order.
2024-03-12work around mypy misdetection on bookwormHelmut Grohne
2024-03-11add method AtLocation.is_absoluteHelmut Grohne
This is similar to pathlib.Path.is_absolute.
2024-03-07add AtLocation.rename method wrapping os.renameHelmut Grohne
2024-03-07add AtLocation.link method wrapping os.linkHelmut Grohne
2024-03-03add function for prctl(PR_CAP_AMBIENT, PR_CAP_AMBIENT_RAISE, ...)Helmut Grohne
2024-03-03implement repr for AtLocationHelmut Grohne
2024-03-02fix typosJakub Wilk
2024-03-01add rudimentary prctl syscall wrapperHelmut Grohne
2024-03-01fix read-only bind_mountHelmut Grohne
As we learn from util-linux, MS_RDONLY is ignored on MS_BIND. Rather than remount, just use the new mount API as it doesn't suffer this limitation.
2024-02-25spell checkHelmut Grohne
2024-02-24populate_dev: remove assumption that newdev does not shadow origdevHelmut Grohne
In particular, one can now pass newdev = origdev.
2024-02-23delete unused importsHelmut Grohne
2024-02-21fix logic error in populate_sysHelmut Grohne
Fixes: 1de72653e0b9 ("add function linuxnamespaces.populate_sys")
2024-02-21improve error handling in linuxnamespaces.populate_devHelmut Grohne
2024-02-21add function linuxnamespaces.populate_sysHelmut Grohne
2024-02-21revoke the false promise that bytes would be convertible to PathHelmut Grohne
pathlib.Path(somebytes) fails. Hence bytes is not actually convertible and should not be included in PathConvertible. Then, we can simplify matters in quite a few places by knowing that the thing we work with is not bytes.
2024-02-16add an async read method to EventFDHelmut Grohne
Adding an async write does not work for values larger than 1, because the fd becomes writable once a value of 1 can be written, but a larger value might still cause EAGAIN putting us into a busy loop. Hitting the limit with writing ones is implausible, so async code can just use the synchronous write method.
2024-02-15MountFlags: support conversion to and from a textual representationHelmut Grohne
The textual representation matches util-linux. Not all flag values can be represented textually.
2024-01-25linuxnamespaces.run_in_fork: use os._exit instead of sys.exitHelmut Grohne
When using sys.exit, we actually raise a SystemExit exception and as a consequence exit all context managers. If a particular context manager pertains only the process at hand, we don't really care, because our process is supposed to vanish. If a context manager changes external state such as tempfile.NamedTemporaryFile, this is very bad and unexpected. We need to ensure that such cleanup is not performed. This also simplifies the test suite that had to emulate this behaviour already as pytest uses a context manager.
2024-01-22provide default for IDAllocation.allocation map arg targetHelmut Grohne
Most frequently, the root user is allocated.
2024-01-19add convenience function unshare_user_idmap_nohelperHelmut Grohne
2024-01-18initial checkinHelmut Grohne
