* bpo-35436: Add missing PyErr_NoMemory() calls and other minor bug fixes. ↵Zackery Spytz2018-12-071-4/+2

* bpo-24658: os.read() reuses _PY_READ_MAX (GH-10657)Miss Islington (bot)2018-11-221-5/+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).

* [3.7]bpo-29341: Backport b942707 3.7 (#10298)BNMetrics2018-11-021-20/+20
| | | | | | | 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-32890, os: Use errno instead of GetLastError() in execve() and ↵Miss Islington (bot)2018-10-201-3/+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.

* bpo-33871: Fix os.sendfile(), os.writev(), os.readv(), etc. (GH-7931)Miss Islington (bot)2018-07-311-17/+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.

* closes bpo-32859: Don't retry dup3() if it is not available at runtime (GH-5708)Miss Islington (bot)2018-02-201-1/+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.
