Update psutil to 7.2.2

[pyup-bot]

This PR updates psutil from 5.9.0 to 7.2.2.

Changelog

7.2.2

=====

2026-01-28

**Enhancements**

- 2705_: [Linux]: `Process.wait()`_ now uses ``pidfd_open()`` + ``poll()`` for
waiting, resulting in no busy loop and faster response times. Requires
Linux >= 5.3 and Python >= 3.9. Falls back to traditional polling if
unavailable.
- 2705_: [macOS], [BSD]: `Process.wait()`_ now uses ``kqueue()`` for waiting,
resulting in no busy loop and faster response times.

**Bug fixes**

- 2701_, [macOS]: fix compilation error on macOS < 10.7.  (patch by Sergey
Fedorov)
- 2707_, [macOS]: fix potential memory leaks in error paths of
`Process.memory_full_info()` and `Process.threads()`.
- 2708_, [macOS]: Process.cmdline()`_ and `Process.environ()`_ may fail with
``OSError: [Errno 0] Undefined error`` (from ``sysctl(KERN_PROCARGS2)``).
They now raise `AccessDenied`_ instead.

7.2.1

=====

2025-12-29

**Bug fixes**

- 2699_, [FreeBSD], [NetBSD]: `heap_info()`_ does not detect small allocations
(<= 1K). In order to fix that, we now flush internal jemalloc cache before
fetching the metrics.

7.2.0

=====

2025-12-23

**Enhancements**

- 1275_: new `heap_info()`_ and `heap_trim()`_ functions, providing direct
access to the platform's native C heap allocator (glibc, mimalloc,
libmalloc). Useful to create tools to detect memory leaks.
- 2403_, [Linux]: publish wheels for Linux musl.
- 2680_: unit tests are no longer installed / part of the distribution. They
now live under `tests/` instead of `psutil/tests`.

**Bug fixes**

* 2684_, [FreeBSD], [critical]: compilation fails on FreeBSD 14 due to missing
include.
* 2691_, [Windows]: fix memory leak in `net_if_stats()`_ due to missing
``Py_CLEAR``.

**Compatibility notes**

- 2680_: `import psutil.tests` no longer works (but it was never documented to
begin with).

7.1.3

=====

2025-11-02

**Enhancements**

- 2667_: enforce `clang-format` on all C and header files. It is now the
mandatory formatting style for all C sources.
- 2672_, [macOS], [BSD]: increase the chances to recognize zombie processes and
raise the appropriate exception (`ZombieProcess`_).
- 2676_, 2678_: replace unsafe `sprintf` / `snprintf` / `sprintf_s` calls with
`str_format()`. Replace `strlcat` / `strlcpy` with safe `str_copy` /
`str_append`. This unifies string handling across platforms and reduces
unsafe usage of standard string functions, improving robustness.

**Bug fixes**

- 2674_, [Windows]: `disk_usage()`_ could truncate values on 32-bit platforms,
potentially reporting incorrect total/free/used space for drives larger than
4GB.
- 2675_, [macOS]: `Process.status()`_ incorrectly returns "running" for 99%
of the processes.
- 2677_, [Windows]: fix MAC address string construction in `net_if_addrs()`_.
Previously, the MAC address buffer was incorrectly updated using a fixed
increment and `sprintf_s`, which could overflow or misformat the
string if the MAC length or formatting changed. Also, the final '\n' was
inserted unnecessarily.
- 2679_, [OpenBSD], [NetBSD], [critical]: can't build due to C syntax error.

7.1.2

=====

2025-10-25

**Enhancements**

- 2657_: stop publishing prebuilt Linux and Windows wheels for 32-bit Python.
32-bit CPython is still supported, but psutil must now be built from source.
2565_: produce wheels for free-thread cPython 3.13 and 3.14 (patch by
Lysandros Nikolaou)

**Bug fixes**

- 2650_, [macOS]: `Process.cmdline()`_ and `Process.environ()`_ may incorrectly
raise `NoSuchProcess`_ instead of `ZombieProcess`_.
- 2658_, [macOS]: double ``free()`` in `Process.environ()`_ when it fails
internally. This posed a risk of segfault.
- 2662_, [macOS]: massive C code cleanup to guard against possible segfaults
which were (not so) sporadically spotted on CI.

**Compatibility notes**

- 2657_: stop publishing prebuilt Linux and Windows wheels for 32-bit Python.

7.1.1

=====

2025-10-19

**Enhancements**

- 2645_, [SunOS]: dropped support for SunOS 10.
- 2646_, [SunOS]: add CI test runner for SunOS.

**Bug fixes**

- 2641_, [SunOS]: cannot compile psutil from sources due to missing C include.
- 2357_, [SunOS]: `Process.cmdline()`_ does not handle spaces properly. (patch
by Ben Raz)

**Compatibility notes**

* 2645_: SunOS 10 is no longer supported.

7.1.0

=====

2025-09-17

**Enhancements**

- 2581_, [Windows]: publish ARM64 wheels.  (patch by Matthieu Darbois)
- 2571_, [FreeBSD]: Dropped support for FreeBSD 8 and earlier. FreeBSD 8 was
maintained from 2009 to 2013.
- 2575_: introduced `dprint` CLI tool to format .yml and .md files.

**Bug fixes**

- 2473_, [macOS]: Fix build issue on macOS 11 and lower.
- 2494_, [Windows]: All APIs dealing with paths, such as
`Process.memory_maps()`_, `Process.exe()`_ and `Process.open_files()`_ does
not properly handle UNC paths. Paths such as ``\\??\\C:\\Windows\\Temp`` and
``'\\Device\\HarddiskVolume1\\Windows\\Temp'`` are now converted to
``C:\\Windows\\Temp``.  (patch by Ben Peddell)
- 2506_, [Windows]: Windows service APIs had issues with unicode services using
special characters in their name.
- 2514_, [Linux]: `Process.cwd()`_ sometimes fail with `FileNotFoundError` due
to a race condition.
- 2526_, [Linux]: `Process.create_time()`_, which is used to univocally
identify a process over time, is subject to system clock updates, and as such
can lead to `Process.is_running()`_ returning a wrong result. A monotonic
creation time is now used instead.  (patch by Jonathan Kohler)
- 2528_, [Linux]: `Process.children()`_ may raise ``PermissionError``. It will
now raise `AccessDenied`_ instead.
- 2540_, [macOS]: `boot_time()`_ is off by 45 seconds (C precision issue).
- 2541_, 2570_, 2578_ [Linux], [macOS], [NetBSD]: `Process.create_time()`_ does
not reflect system clock updates.
- 2542_: if system clock is updated `Process.children()`_ and
`Process.parent()`_ may not be able to return the right information.
- 2545_: [Illumos]: Fix handling of MIB2_UDP_ENTRY in `net_connections()`_.
- 2552_, [Windows]: `boot_time()`_ didn't take into account the time spent
during suspend / hibernation.
- 2560_, [Linux]: `Process.memory_maps()`_ may crash with `IndexError` on
RISCV64 due to a malformed `/proc/{PID}/smaps` file.  (patch by Julien
Stephan)
- 2586_, [macOS], [CRITICAL]: fixed different places in C code which can
trigger a segfault.
- 2604_, [Linux]: `virtual_memory()`_ "used" memory does not match recent
versions of ``free`` CLI utility.  (patch by Isaac K. Ko)
- 2605_, [Linux]: `psutil.sensors_battery()` reports a negative amount for
seconds left.
- 2607_, [Windows]: ``WindowsService.description()`` method may fail with
``ERROR_NOT_FOUND``. Now it returns an empty string instead.
- 2610:, [macOS], [CRITICAL]: fix `cpu_freq()`_ segfault on ARM architectures.

**Compatibility notes**

- 2571_: dropped support for FreeBSD 8 and earlier.

7.0.0

=====

2025-02-13

**Enhancements**

- 669_, [Windows]: `net_if_addrs()`_ also returns the ``broadcast`` address
instead of ``None``.
- 2480_: Python 2.7 is no longer supported. Latest version supporting Python
2.7 is psutil 6.1.X. Install it with: ``pip2 install psutil==6.1.*``.
- 2490_: removed long deprecated ``Process.memory_info_ex()`` method. It was
deprecated in psutil 4.0.0, released 8 years ago. Substitute is
``Process.memory_full_info()``.

**Bug fixes**

- 2496_, [Linux]: Avoid segfault (a cPython bug) on ``Process.memory_maps()``
for processes that use hundreds of GBs of memory.
- 2502_, [macOS]: `virtual_memory()`_ now relies on ``host_statistics64``
instead of ``host_statistics``. This is the same approach used by ``vm_stat``
CLI tool, and should grant more accurate results.

**Compatibility notes**

- 2480_: Python 2.7 is no longer supported.
- 2490_: removed long deprecated ``Process.memory_info_ex()`` method.

6.1.1

=====

2024-12-19

**Enhancements**

- 2471_: use Vulture CLI tool to detect dead code.

**Bug fixes**

- 2418_, [Linux]: fix race condition in case /proc/PID/stat does not exist, but
/proc/PID does, resulting in FileNotFoundError.
- 2470_, [Linux]: `users()`_ may return "localhost" instead of the actual IP
address of the user logged in.

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.
