* 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.

* bpo-32777: Fix _Py_set_inheritable async-safety in subprocess (GH-5560) ↵Miss Islington (bot)2018-02-061-4/+4
| | | | | | | | | | | | (GH-5563) Fix a rare but potential pre-exec child process deadlock in subprocess on POSIX systems when marking file descriptors inheritable on exec in the child process. This bug appears to have been introduced in 3.4 with the inheritable file descriptors support. This also changes Python/fileutils.c `set_inheritable` to use the "slow" two `fcntl` syscall path instead of the "fast" single `ioctl` syscall path when asked to be async signal safe (by way of being asked not to raise exceptions). `ioctl` is not a POSIX async-signal-safe approved function. ref: http://pubs.opengroup.org/onlinepubs/9699919799/functions/V2_chap02.html (cherry picked from commit c1e46e94de38a92f98736af9a42d89c3975a9919) Co-authored-by: Alexey Izbyshev <izbyshev@users.noreply.github.com>

* bpo-31933: fix blake2 multi-byte params on big endian platforms (GH-4250) ↵Miss Islington (bot)2017-11-032-4/+8
| | | | | | | | | | | | | | | (#4262) All Blake2 params have to be encoded in little-endian byte order. For the two multi-byte integer params, leaf_length and node_offset, that means that assigning a native-endian integer to them appears to work on little-endian platforms, but gives the wrong result on big-endian. The current libb2 API doesn't make that very clear, and @sneves is working on new API functions in the GH issue above. In the meantime, we can work around the problem by explicitly assigning little-endian values to the parameter block. See https://github.com/BLAKE2/libb2/issues/12.

| | | | | | | | | | | (GH-4230) (#4253) When a single .c file contains several functions and/or methods with the same name, a safety _METHODDEF GH-define statement is generated only for one of them. This fixes the bug by using the full name of the function to avoid duplicates rather than just the name.. (cherry picked from commit 4f57409a2f7bdf8fb559cddc7c6533ca2c471c67)

* Remove nested comments in blake2 (GH-4173) (#4214)Miss Islington (bot)2017-11-011-2/+4
| | | | | | | | | | | | Replace occurence of nested comments in blake2 reference implementation with preprocessor directive for disabling unused code. `blake2s-load-xop.h` is conditionally pulled in only on chips with XOP support, among others the AMD Bulldozer. The malformed comments in the source file breaks the build of `hashlib`'s `_blake2` on GCC 6.3.0. Official reference code on github uses `GH-if` so this change should be uncontroversial.
