2024-06-18
**Enhancements**
- 2109\_: `maxfile` and `maxpath` fields were removed from the namedtuple
returned by `disk_partitions()`\_. Reason: on network filesystems (NFS) this
can potentially take a very long time to complete.
- 2366\_, \[Windows]: log debug message when using slower process APIs.
- 2375\_, \[macOS]: provide arm64 wheels. (patch by Matthieu Darbois)
- 2396\_: `process_iter()`\_ no longer pre-emptively checks whether PIDs have
been reused. This makes `process_iter()`\_ around 20x times faster.
- 2396\_: a new `psutil.process_iter.cache_clear()` API can be used the clear
`process_iter()`\_ internal cache.
- 2401\_, Support building with free-threaded CPython 3.13. (patch by Sam Gross)
- 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.
- 2425\_: \[Linux]: provide aarch64 wheels. (patch by Matthieu Darbois / Ben Raz)
**Bug fixes**
- 2250\_, \[NetBSD]: `Process.cmdline()`\_ sometimes fail with EBUSY. It usually
happens for long cmdlines with lots of arguments. In this case retry getting
the cmdline for up to 50 times, and return an empty list as last resort.
- 2254\_, \[Linux]: offline cpus raise NotImplementedError in cpu_freq() (patch
by Shade Gladden)
- 2272\_: Add pickle support to psutil Exceptions.
- 2359\_, \[Windows], \[CRITICAL]: `pid_exists()`\_ disagrees with `Process`\_ on
whether a pid exists when ERROR_ACCESS_DENIED.
- 2360\_, \[macOS]: can't compile on macOS < 10.13. (patch by Ryan Schmidt)
- 2362\_, \[macOS]: can't compile on macOS 10.11. (patch by Ryan Schmidt)
- 2365\_, \[macOS]: can't compile on macOS < 10.9. (patch by Ryan Schmidt)
- 2395\_, \[OpenBSD]: `pid_exists()`\_ erroneously return True if the argument is
a thread ID (TID) instead of a PID (process ID).
- 2412\_, \[macOS]: can't compile on macOS 10.4 PowerPC due to missing `MNT_`
constants.
**Porting notes**
Version 6.0.0 introduces some changes which affect backward compatibility:
- 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.

[Compare Source](https://togithub.com/giampaolo/psutil/compare/release-5.9.7...release-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](https://togithub.com/giampaolo/psutil/issues/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.

[Compare Source](https://togithub.com/giampaolo/psutil/compare/release-5.9.6...release-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.
### [`v5.9.6`](https://togithub.com/giampaolo/psutil/blob/HEAD/HISTORY.rst#596)
[Compare Source](https://togithub.com/giampaolo/psutil/compare/release-5.9.5...release-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).

[Compare Source](https://togithub.com/giampaolo/psutil/compare/release-5.9.4...release-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.

\=====
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.

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)

\=====
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

\=====
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.

[Compare Source](https://togithub.com/giampaolo/psutil/compare/release-5.8.0...release-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.

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). ### [`v5.9.5`](https://togithub.com/giampaolo/psutil/blob/HEAD/HISTORY.rst#595) [Compare Source](https://togithub.com/giampaolo/psutil/compare/release-5.9.4...release-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. ### [`v5.9.4`](https://togithub.com/giampaolo/psutil/blob/HEAD/HISTORY.rst#594) [Compare Source](https://togithub.com/giampaolo/psutil/compare/release-5.9.3...release-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) ### [`v5.9.3`](https://togithub.com/giampaolo/psutil/blob/HEAD/HISTORY.rst#593) [Compare Source](https://togithub.com/giampaolo/psutil/compare/release-5.9.2...release-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) ### [`v5.9.2`](https://togithub.com/giampaolo/psutil/blob/HEAD/HISTORY.rst#592) [Compare Source](https://togithub.com/giampaolo/psutil/compare/release-5.9.1...release-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 `#includeConfiguration
