* bpo-40286: Remove C implementation of Random.randbytes() (GH-19797)Victor Stinner2020-04-291-42/+1
| | | | | Remove _random.Random.randbytes(): the C implementation of randbytes(). Implement the method in Python to ease subclassing: randbytes() now directly reuses getrandbits().
* bpo-9216: Expose OpenSSL FIPS_mode() as _hashlib.get_fips_mode() (GH-19703)Victor Stinner2020-04-291-1/+42
| | | | | | test.pythoninfo logs OpenSSL FIPS_mode() and Linux /proc/sys/crypto/fips_enabled in a new "fips" section. Co-Authored-By: Petr Viktorin <encukou@gmail.com>
* bpo-40138: Fix Windows os.waitpid() for large exit code (GH-19637)Victor Stinner2020-04-221-13/+5
| | | | | | | | Fix the Windows implementation of os.waitpid() for exit code larger than "INT_MAX >> 8". The exit status is now interpreted as an unsigned number. os.waitstatus_to_exitcode() now accepts wait status larger than INT_MAX.
* bpo-40178: Convert the remaining os functions to Argument Clinic. (GH-19360)Serhiy Storchaka2020-04-181-1/+558
| | | | | Convert os.getgrouplist(), os.initgroups(), os.sendfile() and os.get_terminal_size().
* bpo-40179: Fix translation of #elif in Argument Clinic (GH-19364)Serhiy Storchaka2020-04-181-3/+3
| | | | Co-authored-by: Ammar Askar <ammar@ammaraskar.com>
* bpo-40286: Add randbytes() method to random.Random (GH-19527)Victor Stinner2020-04-171-1/+42
| | | | | | | | | | | | Add random.randbytes() function and random.Random.randbytes() method to generate random bytes. Modify secrets.token_bytes() to use SystemRandom.randbytes() rather than calling directly os.urandom(). Rename also genrand_int32() to genrand_uint32(), since it returns an unsigned 32-bit integer, not a signed integer. The _random module is now built with Py_BUILD_CORE_MODULE defined.
* bpo-40234: Revert "bpo-37266: Daemon threads are now denied in ↵Victor Stinner2020-04-121-22/+0
| | | | | subinterpreters (GH-14049)" (GH-19456) This reverts commit 066e5b1a917ec2134e8997d2cadd815724314252.
* bpo-40094: Add os.waitstatus_to_exitcode() (GH-19201)Victor Stinner2020-04-011-1/+61
| | | | | | | | | | | | | | Add os.waitstatus_to_exitcode() function to convert a wait status to an exitcode. Suggest waitstatus_to_exitcode() usage in the documentation when appropriate. Use waitstatus_to_exitcode() in: * multiprocessing, os, subprocess and _bootsubprocess modules; * test.support.wait_process(); * setup.py: run_command(); * and many tests.

* bpo-39395: putenv() and unsetenv() always available (GH-18135)Victor Stinner2020-01-241-5/+5
| | | | | | | | The os.putenv() and os.unsetenv() functions are now always available. On non-Windows platforms, Python now requires setenv() and unsetenv() functions to build. Remove putenv_dict from posixmodule.c: it's not longer needed.
* bpo-39413: Implement os.unsetenv() on Windows (GH-18163)Victor Stinner2020-01-241-3/+39
| | | The os.unsetenv() function is now also available on Windows.
* bpo-39426: Fix outdated default and highest protocols in docs (GH-18154)Mark Dickinson2020-01-241-7/+8
| | | | | | Some portions of the pickle documentation hadn't been updated for the pickle protocol changes in Python 3.8 (new protocol 5, default protocol 4). This PR fixes those docs. https://bugs.python.org/issue39426
* bpo-39406: Implement os.putenv() with setenv() if available (GH-18128)Victor Stinner2020-01-221-5/+5
| | | | | If setenv() C function is available, os.putenv() is now implemented with setenv() instead of putenv(), so Python doesn't have to handle the environment variable memory.
* Revert "bpo-39413: Implement os.unsetenv() on Windows (GH-18104)" (GH-18124)Victor Stinner2020-01-221-39/+3
| | | This reverts commit 56cd3710a1ea3ba872d345ea1bebc86ed08bc8b8.
* bpo-39353: Deprecate the binhex module (GH-18025)Victor Stinner2020-01-221-8/+3
| | | | | | | | Deprecate binhex4 and hexbin4 standards. Deprecate the binhex module and the following binascii functions: * b2a_hqx(), a2b_hqx() * rlecode_hqx(), rledecode_hqx() * crc_hqx()
* bpo-39413: Implement os.unsetenv() on Windows (GH-18104)Victor Stinner2020-01-211-3/+39
| | | | | The os.unsetenv() function is now also available on Windows. It is implemented with SetEnvironmentVariableW(name, NULL).
* bpo-39322: Add gc.is_finalized to check if an object has been finalised by ↵Pablo Galindo2020-01-141-1/+10
| | | | the gc (GH-17989)
* bpo-39310: Add math.ulp(x) (GH-17965)Victor Stinner2020-01-131-1/+40
| | | | Add math.ulp(): return the value of the least significant bit of a float.
* bpo-39288: Add math.nextafter(x, y) (GH-17937)Victor Stinner2020-01-121-1/+49
| | | Return the next floating-point value after x towards y.
* bpo-38916: array.array: remove fromstring() and tostring() (GH-17487)Victor Stinner2019-12-091-69/+1
| | | | array.array: Remove tostring() and fromstring() methods. They were aliases to tobytes() and frombytes(), deprecated since Python 3.2.
* closes bpo-38712: Add signal.pidfd_send_signal. (GH-17070)Benjamin Peterson2019-11-191-1/+75
| | | | | | | | This exposes a Linux-specific syscall for sending a signal to a process identified by a file descriptor rather than a pid. For simplicity, we don't support the siginfo_t parameter to the syscall. This parameter allows implementing a pidfd version of rt_sigqueueinfo(2), which Python also doesn't support.
* bpo-38835: Don't use PyFPE_START_PROTECT and PyFPE_END_PROTECT (GH-17231)Victor Stinner2019-11-201-31/+16
| | | | | The PyFPE_START_PROTECT() and PyFPE_END_PROTECT() macros are empty: they have been doing nothing for the last year (since commit 735ae8d139a673b30b321dc10acfd3d14f0d633b), so stop using them.
* bpo-36589: Fix the error handling in curses.update_lines_cols(). (GH-12766)Zackery Spytz2019-11-171-13/+3
| | | | Return None instead of 1.

* bpo-35381 Remove all static state from posixmodule (GH-15892)Eddie Elizondo2019-11-051-2/+2
| | | | | | | | | | | | | | After #9665, this moves the remaining types in posixmodule to be heap-allocated to make it compatible with PEP384 as well as modifying all the type accessors to fully make the type opaque. The original PR that got messed up a rebase: https://github.com/python/cpython/pull/10854. All the issues in that commit have now been addressed since https://github.com/python/cpython/pull/11661 got committed. This change also removes any state from the data segment and onto the module state itself. https://bugs.python.org/issue35381 Automerge-Triggered-By: @encukou

* bpo-38378: Rename parameters "out" and "in" of os.sendfile(). (GH-16742)Serhiy Storchaka2019-10-131-10/+10
| | | | | | | They conflicted with keyword "in". Also rename positional-only parameters of private os._fcopyfile() for consistency.

* bpo-38116: Convert select module to PEP-384 (#15971)Dino Viehland2019-09-141-3/+3
| | | | | | | | | | * Convert select module to PEP-384 Summary: Do the necessary versions to be Pyro-compatible, including migrating `PyType_Ready` to `PyType_FromSpec` and moving static data into a new `_selectstate` struct. * 📜🤖 Added by blurb_it. * Fixup Mac OS/X build
* bpo-37206: Unrepresentable default values no longer represented as None. ↵Serhiy Storchaka2019-09-1411-55/+55
| | | | | | | (GH-13933) In ArgumentClinic, value "NULL" should now be used only for unrepresentable default values (like in the optional third parameter of getattr). "None" should be used if None is accepted as argument and passing None has the same effect as not passing the argument at all.
* bpo-9216: Add usedforsecurity to hashlib constructors (GH-16044)Christian Heimes2019-09-125-83/+272
| | | | | The usedforsecurity keyword only argument added to the hash constructors is useful for FIPS builds and similar restrictive environment with non-technical requirements that legacy algorithms be forbidden by their implementations without being explicitly annotated as not being used for any security related purposes. Linux distros with FIPS support benefit from this being standard rather than making up their own way(s) to do it. Contributed and Signed-off-by: Christian Heimes christian@python.org
