Update psutil to 6.1.0

[pyup-bot]

This PR updates psutil from 5.8.0 to 6.1.0.

Changelog

6.1.0

=====

2024-10-17

**Enhancements**

- 2366_, [Windows]: drastically speedup `process_iter()`_. We now determine
process unique identity by using process "fast" create time method. This
will considerably speedup those apps which use `process_iter()`_ only once,
e.g. to look for a process with a certain name.
- 2446_: use pytest instead of unittest.
- 2448_: add ``make install-sysdeps`` target to install the necessary system
dependencies (python-dev, gcc, etc.) on all supported UNIX flavors.
- 2449_: add ``make install-pydeps-test`` and ``make install-pydeps-dev``
targets. They can be used to install dependencies meant for running tests and
for local development. They can also be installed via ``pip install .[test]``
and ``pip install .[dev]``.
- 2456_: allow to run tests via ``python3 -m psutil.tests`` even if ``pytest``
module is not installed. This is useful for production environments that
don't have pytest installed, but still want to be able to test psutil
installation.

**Bug fixes**

- 2427_: psutil (segfault) on import in the free-threaded (no GIL) version of
Python 3.13.  (patch by Sam Gross)
- 2455_, [Linux]: ``IndexError`` may occur when reading /proc/pid/stat and
field 40 (blkio_ticks) is missing.
- 2457_, [AIX]: significantly improve the speed of `Process.open_files()`_ for
some edge cases.
- 2460_, [OpenBSD]: `Process.num_fds()`_ and `Process.open_files()`_ may fail
with `NoSuchProcess`_ for PID 0. Instead, we now return "null" values (0 and
[] respectively).

6.0.0

- 2109_: the namedtuple returned by `disk_partitions()`_' no longer has
``maxfile`` and ``maxpath`` fields.
- 2396_: `process_iter()`_ no longer pre-emptively checks whether PIDs have
been reused. If you want to check for PID reusage you are supposed to use
`Process.is_running()`_ against the yielded `Process`_ instances. That will
also automatically remove reused PIDs from `process_iter()`_ internal cache.
- 2407_: `Process.connections()`_ was renamed to `Process.net_connections()`_.
The old name is still available, but it's deprecated (triggers a
``DeprecationWarning``) and will be removed in the future.

5.9.8

=====

2024-01-19

**Enhancements**

- 2343_, [FreeBSD]: filter `net_connections()`_ returned list in C instead of
Python, and avoid to retrieve unnecessary connection types unless explicitly
asked. E.g., on an IDLE system with few IPv6 connections this will run around
4 times faster. Before all connection types (TCP, UDP, UNIX) were retrieved
internally, even if only a portion was returned.
- 2342_, [NetBSD]: same as above (2343) but for NetBSD.
- 2349_: adopted black formatting style.

**Bug fixes**

- 930_, [NetBSD], [critical]: `net_connections()`_ implementation was broken.
It could either leak memory or core dump.
- 2340_, [NetBSD]: if process is terminated, `Process.cwd()`_ will return an
empty string instead of raising `NoSuchProcess`_.
- 2345_, [Linux]: fix compilation on older compiler missing DUPLEX_UNKNOWN.
- 2222_, [macOS]: `cpu_freq()` now returns fixed values for `min` and `max`
frequencies in all Apple Silicon chips.

5.9.7

=====

2023-12-17

**Enhancements**

- 2324_: enforce Ruff rule `raw-string-in-exception`, which helps providing
clearer tracebacks when exceptions are raised by psutil.

**Bug fixes**

- 2325_, [PyPy]: psutil did not compile on PyPy due to missing
`PyErr_SetExcFromWindowsErrWithFilenameObject` cPython API.

5.9.6

=====

2023-10-15

**Enhancements**

- 1703_: `cpu_percent()`_ and `cpu_times_percent()`_ are now thread safe,
meaning they can be called from different threads and still return
meaningful and independent results. Before, if (say) 10 threads called
``cpu_percent(interval=None)`` at the same time, only 1 thread out of 10
would get the right result.
- 2266_: if `Process`_ class is passed a very high PID, raise `NoSuchProcess`_
instead of OverflowError.  (patch by Xuehai Pan)
- 2246_: drop python 3.4 & 3.5 support.  (patch by Matthieu Darbois)
- 2290_: PID reuse is now pre-emptively checked for `Process.ppid()`_  and
`Process.parents()`_.
- 2312_: use ``ruff`` Python linter instead of ``flake8 + isort``. It's an
order of magnitude faster + it adds a ton of new code quality checks.

**Bug fixes**

- 2195_, [Linux]: no longer print exception at import time in case /proc/stat
can't be read due to permission error. Redirect it to ``PSUTIL_DEBUG``
instead.
- 2241_, [NetBSD]: can't compile On NetBSD 10.99.3/amd64.  (patch by Thomas
Klausner)
- 2245_, [Windows]: fix var unbound error on possibly in `swap_memory()`_
(patch by student_2333)
- 2268_: ``bytes2human()`` utility function was unable to properly represent
negative values.
- 2252_, [Windows]: `disk_usage()`_ fails on Python 3.12+.  (patch by
Matthieu Darbois)
- 2284_, [Linux]: `Process.memory_full_info()`_ may incorrectly raise
`ZombieProcess`_ if it's determined via ``/proc/pid/smaps_rollup``. Instead
we now fallback on reading ``/proc/pid/smaps``.
- 2287_, [OpenBSD], [NetBSD]: `Process.is_running()`_ erroneously return
``False`` for zombie processes, because creation time cannot be determined.
- 2288_, [Linux]: correctly raise `ZombieProcess`_ on `Process.exe()`_,
`Process.cmdline()`_ and `Process.memory_maps()`_ instead of returning a
"null" value.
- 2290_: differently from what stated in the doc, PID reuse is not
pre-emptively checked for `Process.nice()`_ (set), `Process.ionice()`_,
(set), `Process.cpu_affinity()`_ (set), `Process.rlimit()`_
(set), `Process.parent()`_.
- 2308_, [OpenBSD]: `Process.threads()`_ always fail with AccessDenied (also as
root).

5.9.5

=====

2023-04-17

**Enhancements**

- 2196_: in case of exception, display a cleaner error traceback by hiding the
`KeyError` bit deriving from a missed cache hit.
- 2217_: print the full traceback when a `DeprecationWarning` or `UserWarning`
is raised.
- 2230_, [OpenBSD]: `net_connections()`_ implementation was rewritten
from scratch:
- We're now able to retrieve the path of AF_UNIX sockets (before it was an
empty string)
- The function is faster since it no longer iterates over all processes.
- No longer produces duplicate connection entries.
- 2238_: there are cases where `Process.cwd()`_ cannot be determined
(e.g. directory no longer exists), in which case we returned either ``None``
or an empty string. This was consolidated and we now return ``""`` on all
platforms.
- 2239_, [UNIX]: if process is a zombie, and we can only determine part of the
its truncated `Process.name()`_ (15 chars), don't fail with `ZombieProcess`_
when we try to guess the full name from the `Process.cmdline()`_. Just
return the truncated name.
- 2240_, [NetBSD], [OpenBSD]: add CI testing on every commit for NetBSD and
OpenBSD platforms (python 3 only).

**Bug fixes**

- 1043_, [OpenBSD] `net_connections()`_ returns duplicate entries.
- 1915_, [Linux]: on certain kernels, ``"MemAvailable"`` field from
``/proc/meminfo`` returns ``0`` (possibly a kernel bug), in which case we
calculate an approximation for ``available`` memory which matches "free"
CLI utility.
- 2164_, [Linux]: compilation fails on kernels < 2.6.27 (e.g. CentOS 5).
- 2186_, [FreeBSD]: compilation fails with Clang 15.  (patch by Po-Chuan Hsieh)
- 2191_, [Linux]: `disk_partitions()`_: do not unnecessarily read
/proc/filesystems and raise `AccessDenied`_ unless user specified `all=False`
argument.
- 2216_, [Windows]: fix tests when running in a virtual environment (patch by
Matthieu Darbois)
- 2225_, [POSIX]: `users()`_ loses precision for ``started`` attribute (off by
1 minute).
- 2229_, [OpenBSD]: unable to properly recognize zombie processes.
`NoSuchProcess`_ may be raised instead of `ZombieProcess`_.
- 2231_, [NetBSD]: *available*  `virtual_memory()`_ is higher than *total*.
- 2234_, [NetBSD]: `virtual_memory()`_ metrics are wrong: *available* and
*used* are too high. We now match values shown by *htop* CLI utility.
- 2236_, [NetBSD]: `Process.num_threads()`_ and `Process.threads()`_ return
threads that are already terminated.
- 2237_, [OpenBSD], [NetBSD]: `Process.cwd()`_ may raise ``FileNotFoundError``
if cwd no longer exists. Return an empty string instead.

5.9.4

=====

2022-11-07

**Enhancements**

- 2102_: use Limited API when building wheels with CPython 3.6+ on Linux,
macOS and Windows. This allows to use pre-built wheels in all future versions
of cPython 3.  (patch by Matthieu Darbois)

**Bug fixes**

- 2077_, [Windows]: Use system-level values for `virtual_memory()`_. (patch by
Daniel Widdis)
- 2156_, [Linux]: compilation may fail on very old gcc compilers due to missing
``SPEED_UNKNOWN`` definition.  (patch by Amir Rossert)
- 2010_, [macOS]: on MacOS, arm64 ``IFM_1000_TX`` and ``IFM_1000_T`` are the
same value, causing a build failure.  (patch by Lawrence D'Anna)
- 2160_, [Windows]: Get Windows percent swap usage from performance counters.
(patch by Daniel Widdis)

5.9.3

=====

2022-10-18

**Enhancements**

- 2040_, [macOS]: provide wheels for arm64 architecture.  (patch by Matthieu
Darbois)

**Bug fixes**

- 2116_, [macOS], [critical]: `net_connections()`_ fails with RuntimeError.
- 2135_, [macOS]: `Process.environ()`_ may contain garbage data. Fix
out-of-bounds read around ``sysctl_procargs``.  (patch by Bernhard Urban-Forster)
- 2138_, [Linux], **[critical]**: can't compile psutil on Android due to
undefined ``ethtool_cmd_speed`` symbol.
- 2142_, [POSIX]: `net_if_stats()`_ 's ``flags`` on Python 2 returned unicode
instead of str.  (patch by Matthieu Darbois)
- 2147_, [macOS] Fix disk usage report on macOS 12+.  (patch by Matthieu Darbois)
- 2150_, [Linux] `Process.threads()`_ may raise ``NoSuchProcess``. Fix race
condition.  (patch by Daniel Li)
- 2153_, [macOS] Fix race condition in test_posix.TestProcess.test_cmdline.
(patch by Matthieu Darbois)

5.9.2

=====

2022-09-04

**Bug fixes**

- 2093_, [FreeBSD], **[critical]**: `pids()`_ may fail with ENOMEM. Dynamically
increase the ``malloc()`` buffer size until it's big enough.
- 2095_, [Linux]: `net_if_stats()`_ returns incorrect interface speed for
100GbE network cards.
- 2113_, [FreeBSD], **[critical]**: `virtual_memory()`_ may raise ENOMEM due to
missing ``include <sys/param.h>`` directive.  (patch by Peter Jeremy)
- 2128_, [NetBSD]: `swap_memory()`_ was miscalculated.  (patch by Thomas Klausner)

5.9.1

=====

2022-05-20

**Enhancements**

- 1053_: drop Python 2.6 support.  (patches by Matthieu Darbois and Hugo van
Kemenade)
- 2037_: Add additional flags to net_if_stats.
- 2050_, [Linux]: increase ``read(2)`` buffer size from 1k to 32k when reading
``/proc`` pseudo files line by line. This should help having more consistent
results.
- 2057_, [OpenBSD]: add support for `cpu_freq()`_.
- 2107_, [Linux]: `Process.memory_full_info()`_ (reporting process USS/PSS/Swap
memory) now reads ``/proc/pid/smaps_rollup`` instead of ``/proc/pids/smaps``,
which makes it 5 times faster.

**Bug fixes**

- 2048_: ``AttributeError`` is raised if ``psutil.Error`` class is raised
manually and passed through ``str``.
- 2049_, [Linux]: `cpu_freq()`_ erroneously returns ``curr`` value in GHz while
``min`` and ``max`` are in MHz.
- 2050_, [Linux]: `virtual_memory()`_ may raise ``ValueError`` if running in a
LCX container.

5.9.0

=====

2021-12-29

**Enhancements**

- 1851_, [Linux]: `cpu_freq()`_ is slow on systems with many CPUs. Read current
frequency values for all CPUs from ``/proc/cpuinfo`` instead of opening many
files in ``/sys`` fs.  (patch by marxin)
- 1992_: `NoSuchProcess`_ message now specifies if the PID has been reused.
- 1992_: error classes (`NoSuchProcess`_, `AccessDenied`_, etc.) now have a better
formatted and separated ``__repr__`` and ``__str__`` implementations.
- 1996_, [BSD]: add support for MidnightBSD.  (patch by Saeed Rasooli)
- 1999_, [Linux]: `disk_partitions()`_: convert ``/dev/root`` device (an alias
used on some Linux distros) to real root device path.
- 2005_: ``PSUTIL_DEBUG`` mode now prints file name and line number of the debug
messages coming from C extension modules.
- 2042_: rewrite HISTORY.rst to use hyperlinks pointing to psutil API doc.

**Bug fixes**

- 1456_, [macOS], **[critical]**: `cpu_freq()`_ ``min`` and ``max`` are set to
0 if can't be determined (instead of crashing).
- 1512_, [macOS]: sometimes `Process.connections()`_ will crash with
``EOPNOTSUPP`` for one connection; this is now ignored.
- 1598_, [Windows]: `disk_partitions()`_ only returns mountpoints on drives
where it first finds one.
- 1874_, [SunOS]: swap output error due to incorrect range.
- 1892_, [macOS]: `cpu_freq()`_ broken on Apple M1.
- 1901_, [macOS]: different functions, especially `Process.open_files()`_ and
`Process.connections()`_, could randomly raise `AccessDenied`_ because the
internal buffer of ``proc_pidinfo(PROC_PIDLISTFDS)`` syscall was not big enough.
We now dynamically increase the buffer size until it's big enough instead of
giving up and raising `AccessDenied`_, which was a fallback to avoid crashing.
- 1904_, [Windows]: ``OpenProcess`` fails with ``ERROR_SUCCESS`` due to
``GetLastError()`` called after ``sprintf()``.  (patch by alxchk)
- 1913_, [Linux]: `wait_procs()`_ should catch ``subprocess.TimeoutExpired``
exception.
- 1919_, [Linux]: `sensors_battery()`_ can raise ``TypeError`` on PureOS.
- 1921_, [Windows]: `swap_memory()`_ shows committed memory instead of swap.
- 1940_, [Linux]: psutil does not handle ``ENAMETOOLONG`` when accessing process
file descriptors in procfs.  (patch by Nikita Radchenko)
- 1948_, **[critical]**: ``memoize_when_activated`` decorator is not thread-safe.
(patch by Xuehai Pan)
- 1953_, [Windows], **[critical]**: `disk_partitions()`_ crashes due to
insufficient buffer len. (patch by MaWe2019)
- 1965_, [Windows], **[critical]**: fix "Fatal Python error: deallocating None"
when calling `users()`_ multiple times.
- 1980_, [Windows]: 32bit / WoW64 processes fails to read `Process.name()`_ longer
than 128 characters resulting in `AccessDenied`_. This is now fixed.  (patch
by PetrPospisil)
- 1991_, **[critical]**: `process_iter()`_ is not thread safe and can raise
``TypeError`` if invoked from multiple threads.
- 1956_, [macOS]: `Process.cpu_times()`_ reports incorrect timings on M1 machines.
(patch by Olivier Dormond)
- 2023_, [Linux]: `cpu_freq()`_ return order is wrong on systems with more than
9 CPUs.
