* bpo-35436: Add missing PyErr_NoMemory() calls and other minor bug fixes. ↵Serhiy Storchaka2018-12-071-4/+2
| | | | | | | | | (GH-11015) (GH-11020) (GH-11026) (cherry picked from commit 4c49da0cb7434c676d70b9ccf38aca82ac0d64a9) (cherry picked from commit 602d307ac5e8a2da38a193dca3bdfef5994dfe67) Co-authored-by: Zackery Spytz <zspytz@gmail.com>

| | | | | (cherry picked from commit 32bc11c33cf5ccea165b5f4ac3799f02fdf9c76a) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
* 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). (cherry picked from commit 9a0d7a7648547ffb77144bf2480155f6d7940dea) Co-authored-by: Victor Stinner <vstinner@redhat.com>
* [3.6]bpo-29341: Backport b942707 3.6 (GH-10299)BNMetrics2018-11-021-18/+18
| | | | | | | 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.. (cherry picked from commit b942707fc23454a998323c17e30be78ff1a4f0e7) Co-authored-by: BNMetrics <luna@bnmetrics.com>
* 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. (cherry picked from commit 834603112e6ca35944dd21105b01fca562dc3241) Co-authored-by: Alexey Izbyshev <izbyshev@ispras.ru>
* [3.6] bpo-33871: Fix os.sendfile(), os.writev(), os.readv(), etc. (GH-7931) ↵Serhiy Storchaka2018-07-311-16/+17
| | | | | | | | | | | | | | (GH-8584) * Fix integer overflow in os.readv(), os.writev() 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. (cherry picked from commit 9d5727326af53ddd91016d98e16ae7cf829caa95)

* closes bpo-32859: Don't retry dup3() if it is not available at runtime (GH-5708)Miss Islington (bot)2018-02-211-1/+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.
