Changelog

5.9.1

=====

2022-05-20

**Enhancements**

- 1053_: drop Python 2.6 support.  (patches by Matthieu Darbois and Hugo van
Kemenade)
- 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.

5.8.0

=====

2020-12-19

**Enhancements**

- 1863_: `disk_partitions()`_ exposes 2 extra fields: ``maxfile`` and ``maxpath``,
which are the maximum file name and path name length.

AppVeyor is still being used for Windows CI.

**Bug fixes**

- 1708_, [Linux]: get rid of `sensors_temperatures()`_ duplicates.  (patch by Tim
Schlueter).

``WindowsError`` when failing to query 64 processes from 32 bit ones by using
``NtWoW64`` APIs.
- 1866_, [Windows], **[critical]**: `Process.exe()`_, `Process.cmdline()`_,
`Process.environ()`_ may raise "[WinError 998] Invalid access to memory
location" on Python 3.9 / VS 2019.
- 1874_, [SunOS]: wrong swap output given when encrypted column is present.
- 1875_, [Windows], **[critical]**: `Process.username()`_ may raise
``ERROR_NONE_MAPPED`` if the SID has no corresponding account name. In this
case `AccessDenied`_ is now raised.
- 1886_, [macOS]: ``EIO`` error may be raised on `Process.cmdline()`_ and
`Process.environ()`_. Now it gets translated into `AccessDenied`_.
- 1887_, [Windows], **[critical]**: ``OpenProcess`` may fail with
"[WinError 0] The operation completed successfully"."
Turn it into `AccessDenied`_ or `NoSuchProcess`_ depending on whether the
PID is alive.

(patch by aristocratos)

**Bug fixes**

- 1620_, [Linux]: `cpu_count()`_ with ``logical=False`` result is incorrect on

alive but the exe file which launched it got deleted.
- 1791_, [macOS]: fix missing include for ``getpagesize()``.
- 1823_, [Windows], **[critical]**: `Process.open_files()`_ may cause a segfault
due to a NULL pointer.
- 1838_, [Linux]: `sensors_battery()`_: if `percent` can be determined but not
the remaining values, still return a result instead of ``None``.
(patch by aristocratos)

- 1627_, [Linux]: `Process.memory_maps()`_ can raise ``KeyError``.
- 1642_, [SunOS]: querying basic info for PID 0 results in ``FileNotFoundError``.
- 1646_, [FreeBSD], **[critical]**: many `Process`_ methods may cause a segfault
due to a backward incompatible change in a C type on FreeBSD 12.0.
- 1656_, [Windows]: `Process.memory_full_info()`_ raises `AccessDenied`_ even for the
current user and os.getpid().
- 1660_, [Windows]: `Process.open_files()`_ complete rewrite + check of errors.
- 1662_, [Windows], **[critical]**: `Process.exe()`_ may raise "[WinError 0]

added to recent kernels.  (patch by Mike Hommey)
- 1672_: use the right C type when dealing with PIDs (int or long). Thus far
(long) was almost always assumed, which is wrong on most platforms.
- 1673_, [OpenBSD]: `Process.connections()`_, `Process.num_fds()`_ and
`Process.threads()`_ returned improper exception if process is gone.
- 1674_, [SunOS]: `disk_partitions()`_ may raise ``OSError``.
- 1684_, [Linux]: `disk_io_counters()`_ may raise ``ValueError`` on systems not
having ``/proc/diskstats``.

calculation, including on Windows (emulated).  (patch by Ammar Askar)
- 1404_, [Linux]: `cpu_count()`_ with ``logical=False`` uses a second method
(read from ``/sys/devices/system/cpu/cpu[0-9]/topology/core_id``) in order to
determine the number of CPU cores in case ``/proc/cpuinfo`` does not provide this
info.
- 1458_: provide coloured test output. Also show failures on
``KeyboardInterrupt``.
- 1464_: various docfixes (always point to Python 3 doc, fix links, etc.).
- 1476_, [Windows]: it is now possible to set process high I/O priority
(`Process.ionice()`_). Also, I/O priority values are now exposed as 4 new
constants: ``IOPRIO_VERYLOW``, ``IOPRIO_LOW``, ``IOPRIO_NORMAL``,
``IOPRIO_HIGH``.

- 1474_: fix formatting of ``psutil.tests()`` which mimicks ``ps aux`` output.
- 1475_, [Windows], **[critical]**: ``OSError.winerror`` attribute wasn't
properly checked resuling in ``WindowsError(ERROR_ACCESS_DENIED)`` being
raised instead of `AccessDenied`_.
- 1477_, [Windows]: wrong or absent error handling for private ``NTSTATUS``
Windows APIs. Different process methods were affected by this.
- 1480_, [Windows], **[critical]**: `cpu_count()`_ with ``logical=False`` could

- 1486_, [AIX], [SunOS]: ``AttributeError`` when interacting with `Process`_
methods involved into `Process.oneshot()`_ context.
- 1491_, [SunOS]: `net_if_addrs()`_: use ``free()`` against ``ifap`` struct

calculate USS memory.

5.6.0

=====

2019-03-05

**Enhancements**

- 1379_, [Windows]: `Process.suspend()`_ and `Process.resume()`_ now use
``NtSuspendProcess`` and ``NtResumeProcess`` instead of stopping/resuming all
threads of a process. This is faster and more reliable (aka this is what
ProcessHacker does).
- 1420_, [Windows]: in case of exception `disk_usage()`_ now also shows the path
name.
- 1422_, [Windows]: Windows APIs requiring to be dynamically loaded from DLL
libraries are now loaded only once on startup (instead of on per function
call) significantly speeding up different functions and methods.
- 1426_, [Windows]: ``PAGESIZE`` and number of processors is now calculated on
startup.
- 1428_: in case of error, the traceback message now shows the underlying C
function called which failed.
- 1433_: new `Process.parents()`_ method.  (idea by Ghislain Le Meur)

- 1394_, [Windows], **[critical]**: `Process.name()`_ and `Process.exe()`_ may
erroneously return "Registry" or fail with "[Error 0] The operation completed
successfully".
``QueryFullProcessImageNameW`` is now used instead of
``GetProcessImageFileNameW`` in order to prevent that.
- 1411_, [BSD]: lack of ``Py_DECREF`` could cause segmentation fault on process
instantiation.
- 1419_, [Windows]: `Process.environ()`_ raises ``NotImplementedError`` when
querying a 64-bit process in 32-bit-WoW mode. Now it raises `AccessDenied`_.
- 1427_, [OSX]: `Process.cmdline()`_ and `Process.environ()`_ may erroneously
raise ``OSError`` on failed ``malloc()``.
- 1429_, [Windows]: ``SE DEBUG`` was not properly set for current process. It is
now, and it should result in less `AccessDenied`_ exceptions for low PID
processes.
- 1432_, [Windows]: `Process.memory_info_ex()`_'s USS memory is miscalculated
because we're not using the actual system ``PAGESIZE``.
- 1439_, [NetBSD]: `Process.connections()`_ may return incomplete results if using
`Process.oneshot()`_.
- 1447_: original exception wasn't turned into `NoSuchProcess`_ / `AccessDenied`_
exceptions when using `Process.oneshot()`_ context manager.

**Incompatible API changes**

- 1291_, [OSX], **[critical]**: `Process.memory_maps()`_ was removed because
inherently broken (segfault) for years.

successfully" when Python process runs in "Virtual Secure Mode".
- 1402_: psutil exceptions' ``repr()`` show the internal private module path.
- 1408_, [AIX], **[critical]**: psutil won't compile on AIX 7.1 due to missing
header.  (patch by Arnon Yaari)

EccoTheFlintstone)
- 1370_, [Windows]: improper usage of ``CloseHandle()`` may lead to override the
original error code when raising an exception.
- 1373_, **[critical]**: incorrect handling of cache in `Process.oneshot()`_
context causes `Process`_ instances to return incorrect results.
- 1376_, [Windows]: ``OpenProcess`` now uses ``PROCESS_QUERY_LIMITED_INFORMATION``
access rights wherever possible, resulting in less `AccessDenied`_ exceptions
being thrown for system processes.
- 1376_, [Windows]: check if variable is ``NULL`` before ``free()`` ing it.

**Enhancements**

- 1239_, [Linux]: expose kernel ``slab`` memory field for `virtual_memory()`_.
(patch by Maxime Mouial)

**Bug fixes**

- 694_, [SunOS]: `Process.cmdline()`_ could be truncated at the 15th character when
reading it from ``/proc``. An extra effort is made by reading it from process
address space first.  (patch by Georg Sauthoff)
- 771_, [Windows]: `cpu_count()`_ (both logical and cores) return a wrong
(smaller) number on systems using process groups (> 64 cores).
- 771_, [Windows]: `cpu_times()`_ with ``percpu=True`` return fewer CPUs on
systems using process groups (> 64 cores).
- 771_, [Windows]: `cpu_stats()`_ and `cpu_freq()`_ may return incorrect results on
systems using process groups (> 64 cores).
- 1193_, [SunOS]: return uid/gid from ``/proc/pid/psinfo`` if there aren't
enough permissions for ``/proc/pid/cred``.  (patch by Georg Sauthoff)
- 1194_, [SunOS]: return nice value from ``psinfo`` as ``getpriority()`` doesn't
support real-time processes.  (patch by Georg Sauthoff)
- 1194_, [SunOS]: fix double ``free()`` in `Process.cpu_num()`_.  (patch by Georg
Sauthoff)
- 1194_, [SunOS]: fix undefined behavior related to strict-aliasing rules
and warnings.  (patch by Georg Sauthoff)
- 1210_, [Linux]: `cpu_percent()`_ steal time may remain stuck at 100% due to Linux
erroneously reporting a decreased steal time between calls. (patch by Arnon
Yaari)
- 1216_: fix compatibility with Python 2.6 on Windows (patch by Dan Vinakovsky)
- 1222_, [Linux]: `Process.memory_full_info()`_ was erroneously summing "Swap:" and
"SwapPss:". Same for "Pss:" and "SwapPss". Not anymore.
- 1224_, [Windows]: `Process.wait()`_ may erroneously raise `TimeoutExpired`_.
- 1238_, [Linux]: `sensors_battery()`_ may return ``None`` in case battery is not
listed as "BAT0" under ``/sys/class/power_supply``.
- 1240_, [Windows]: `cpu_times()`_ float loses accuracy in a long running system.
(patch by stswandering)
- 1245_, [Linux]: `sensors_temperatures()`_ may fail with ``IOError`` "no such file".
- 1255_, [FreeBSD]: `swap_memory()`_ stats were erroneously represented in KB.
(patch by Denis Krienbühl)

**Backward compatibility**

- 771_, [Windows]: `cpu_count()`_ with ``logical=False`` on Windows XP and Vista
is no longer supported and returns ``None``.
