* bpo-35371: Fix possible crash in os.utime() on Windows. (GH-10844)Serhiy Storchaka2018-12-011-22/+15
|
* bpo-33012: Fix invalid function cast warnings with gcc 8. (GH-6749)Serhiy Storchaka2018-11-271-1/+1
| | | | | | Fix invalid function cast warnings with gcc 8 for method conventions different from METH_NOARGS, METH_O and METH_VARARGS excluding Argument Clinic generated code.
* bpo-24658: os.read() reuses _PY_READ_MAX (GH-10657)Victor Stinner2018-11-221-5/+1
| | | | | os_read_impl() now also truncates the size to _PY_READ_MAX on macOS, to avoid to allocate a larger buffer even if _Py_read() is limited to _PY_READ_MAX bytes (ex: INT_MAX on macOS).
* bpo-34784: Fix PyStructSequence_NewType with heap-allocated StructSequence ↵Eddie Elizondo2018-11-131-41/+53
| | | | (GH-9665)
* bpo-35081: Rename internal headers (GH-10275)Victor Stinner2018-11-121-1/+1
| | | | | | | | | | | | | | Rename Include/internal/ headers: * pycore_hash.h -> pycore_pyhash.h * pycore_lifecycle.h -> pycore_pylifecycle.h * pycore_mem.h -> pycore_pymem.h * pycore_state.h -> pycore_pystate.h Add missing headers to Makefile.pre.in and PCbuild: * pycore_condvar.h. * pycore_hamt.h * pycore_pyhash.h
* bpo-29341: Clarify that path-like objects are accepted in some os methods ↵BNMetrics2018-11-021-20/+20
| | | | | (GH-10101) Some methods in the os module can accept path-like objects. This is documented in the general documentation but not in the function docstrings. To keep both in sync, the docstrings need to be updated to reflect that path-like objects are also accepted.
* bpo-35081: Add pycore_ prefix to internal header files (GH-10263)Victor Stinner2018-10-311-1/+1
| | | | | | | | | | | | | | | | | | | | * Rename Include/internal/ header files: * pyatomic.h -> pycore_atomic.h * ceval.h -> pycore_ceval.h * condvar.h -> pycore_condvar.h * context.h -> pycore_context.h * pygetopt.h -> pycore_getopt.h * gil.h -> pycore_gil.h * hamt.h -> pycore_hamt.h * hash.h -> pycore_hash.h * mem.h -> pycore_mem.h * pystate.h -> pycore_state.h * warnings.h -> pycore_warnings.h * PCbuild project, Makefile.pre.in, Modules/Setup: add the Include/internal/ directory to the search paths of header files. * Update includes. For example, replace #include "internal/mem.h" with #include "pycore_mem.h".
* bpo-32890, os: Use errno instead of GetLastError() in execve() and ↵Alexey Izbyshev2018-10-201-3/+15
| | | | | | | | | | truncate() (GH-5784) path_error() uses GetLastError() on Windows, but some os functions are implemented via CRT APIs which report errors via errno. This may result in raising OSError with invalid error code (such as zero). Introduce posix_path_error() function and use it where appropriate.
* closes bpo-34862: Guard definition of convert_sched_param with ↵William Orr2018-10-021-4/+6
| | | | | | POSIX_SPAWN_SETSCHEDULER. (GH-9658) Fixes broken build on OpenBSD-current.
* bpo-32557: allow shutil.disk_usage to take a file path on Windows also (GH-9372)Joe Pamer2018-09-251-2/+27
| | | https://bugs.python.org/issue32557
* bpo-33721: Make some os.path functions and pathlib.Path methods be tolerant ↵Serhiy Storchaka2018-09-181-4/+14
| | | | | | | | | | to invalid paths. (#7695) Such functions as os.path.exists(), os.path.lexists(), os.path.isdir(), os.path.isfile(), os.path.islink(), and os.path.ismount() now return False instead of raising ValueError or its subclasses UnicodeEncodeError and UnicodeDecodeError for paths that contain characters or bytes unrepresentative at the OS level.
* Convert os.readlink() to Argument Clinic. (GH-8778)Serhiy Storchaka2018-09-171-83/+71
| | | Also convert os.get_blocking() and os.set_blocking().
* bpo-34651: Only allow the main interpreter to fork. (gh-9279)Eric Snow2018-09-141-0/+14
| | | | | When os.fork() is called (on platforms that support it) all threads but the current one are destroyed in the child process. Consequently we must ensure that all but the associated interpreter are likewise destroyed. The main interpreter is critical for runtime operation, so we must ensure that fork only happens in the main interpreter. https://bugs.python.org/issue34651
* bpo-34674: Assume unistd.h exists on Unix. (GH-9290)Benjamin Peterson2018-09-141-35/+0
|
* bpo-31577: Fix a crash in os.utime() in case of a bad ns argument. (GH-3752)Oren Milman2018-09-121-0/+6
|
* closes bpo-34646: Remove PyAPI_* macros from declarations. (GH-9218)Benjamin Peterson2018-09-121-2/+2
|
* bpo-20104: Change the file_actions parameter of os.posix_spawn(). (GH-6725)Serhiy Storchaka2018-09-081-4/+5
| | | | | * Make its default value an empty tuple instead of None. * Make it a keyword-only parameter.
* bpo-20104: Add flag capabilities to posix_spawn (GH-6693)Pablo Galindo2018-09-071-4/+136
| | | Implement the "attributes objects" parameter of `os.posix_spawn` to complete the implementation and fully cover the underlying API.
* bpo-34384: Fix os.readlink() on Windows (GH-8740)Berker Peksag2018-08-151-59/+34
| | | | | | | | | os.readlink() now accepts path-like and bytes objects on Windows. Previously, support for path-like and bytes objects was only implemented on Unix. This commit also merges Unix and Windows implementations of os.readlink() in one function and adds basic unit tests to increase test coverage of the function.
* bpo-34301: Add _PyInterpreterState_Get() helper function (GH-8592)Victor Stinner2018-08-031-4/+4
| | | | sys_setcheckinterval() now uses a local variable to parse arguments, before writing into interp->check_interval.
* bpo-33871: Fix os.sendfile(), os.writev(), os.readv(), etc. (GH-7931)Serhiy Storchaka2018-07-311-17/+20
| | | | | | | | | | | | * Fix integer overflow in os.readv(), os.writev(), os.preadv() and os.pwritev() and in os.sendfile() with headers or trailers arguments (on BSD-based OSes and MacOS). * Fix sending the part of the file in os.sendfile() on MacOS. Using the trailers argument could cause sending more bytes from the input file than was specified. Thanks Ned Deily for testing on 32-bit MacOS.
* bpo-33671 / shutil.copyfile: use memoryview() with dynamic size on Windows ↵Giampaolo Rodola2018-06-191-2/+2
| | | | | | | | | | (#7681) bpo-33671 * use memoryview() with size == file size on Windows, see https://github.com/python/cpython/pull/7160#discussion_r195405230 * release intermediate (sliced) memoryview immediately * replace "OSX" occurrences with "macOS" * add some unittests for copyfileobj()

| | | | posix_spawn(). (GH-7685)
* bpo-33671: efficient zero-copy for shutil.copy* functions (Linux, OSX and ↵Giampaolo Rodola2018-06-121-0/+37

* Remove unneeded PyErr_Occurred() check in os_lseek_impl() (GH-7557)Zackery Spytz2018-06-101-3/+0
| | | | | This call became unneeded after the posix module was converted to the Argument Clinic in 2f93635d342a500053e97c9c7c30f1eaf11fc3ac and should have been removed as part of that change.
* bpo-33441: Make the sigset_t converter available in other modules. (GH-6720)Serhiy Storchaka2018-05-081-0/+59
| | | | | | | | | * Expose the sigset_t converter via private API _Py_Sigset_Converter(). * Use Argument Clinic for parsing sigset_t in signalmodule.c. * Raise ValueError instead OverflowError for integers out of the C long range. Based on patch by Pablo Galindo Salgado.

* closes bpo-32859: Don't retry dup3() if it is not available at runtime (GH-5708)Alexey Izbyshev2018-02-201-1/+1
| | | | | | | | os.dup2() tests for dup3() system call availability at runtime, but doesn't remember the result across calls, repeating the test on each call with inheritable=False. Since the caller of os.dup2() is expected to hold the GIL, fix this by making the variable holding the test result static.

* bpo-30768: Recompute timeout on interrupted lock (GH-4103)Victor Stinner2017-10-241-3/+1
| | | | | | | | | | | | | | | | Fix the pthread+semaphore implementation of PyThread_acquire_lock_timed() when called with timeout > 0 and intr_flag=0: recompute the timeout if sem_timedwait() is interrupted by a signal (EINTR). See also the PEP 475. The pthread implementation of PyThread_acquire_lock() now fails with a fatal error if the timeout is larger than PY_TIMEOUT_MAX, as done in the Windows implementation. The check prevents any risk of overflow in PyThread_acquire_lock(). Add also PY_DWORD_MAX constant.
