5.8.1 (IN DEVELOPMENT)

XXXX-XX-XX

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)

Bug fixes

1456: [macOS] psutil.cpu_freq()'s 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.
1892: [macOS] psutil.cpu_freq() broken on Apple M1.

1913: [Linux] wait_procs seemingly ignoring timeout, TimeoutExpired thrown
1921: [Windows] psutil.swap_memory() shows committed memory instead of swap

1598: [Windows] psutil.disk_partitions() only returns mountpoints on drives where it first finds one

5.8.0

Enhancements

1863: disk_partitions() exposes 2 extra fields: maxfile and maxpath, which are the maximum file name and path name length.
1872: [Windows] added support for PyPy 2.7.
1879: provide pre-compiled wheels for Linux and macOS (yey!).
1880: get rid of Travis and Cirrus CI services (they are no longer free). CI testing is now done by GitHub Actions on Linux, macOS and FreeBSD (yes). AppVeyor is still being used for Windows CI.

1874: [Solaris] wrong swap output given when encrypted column is present.
1875: [Windows] process username() may raise ERROR_NONE_MAPPED if the SID has no corresponding account name. In this case AccessDenied is now raised.
1877: [Windows] OpenProcess may fail with ERROR_SUCCESS. Turn it into AccessDenied or NoSuchProcess depending on whether the PID is alive.

<Negsignal.SIGTERM: -15>
```
1747: Process.wait() return value is cached so that the exit code can be retrieved on then next call.

1747: Process provides more info about the process on str() and repr() (status and exit code):

>>> proc
psutil.Process(pid=12739, name='python3', status='terminated',
               exitcode=<Negsigs.SIGTERM: -15>, started='15:08:20')

API changes

For the sake of consistency a lot of psutil APIs have been renamed. In most cases accessing the old names will work but it will cause a DeprecationWarning.

psutil.* module level constants have being replaced by functions:

Old name

Replacement

psutil.NUM_CPUS

psutil.cpu_cpunt()

psutil.BOOT_TIME

psutil.boot_time()

psutil.TOTAL_PHYMEM

psutil.virtual_memory().total
Renamed psutil.* functions:
Old name

Replacement
psutil.get_pid_list()

psutil.pids()
psutil.get_users()

psutil.users()
psutil.get_boot_time()

psutil.boot_time()

All psutil.Process get_* methods lost the get_ prefix. get_ext_memory_info() renamed to memory_info_ex(). Assuming "p = psutil.Process()":

Old name	Replacement
p.get_children()	p.children()
p.get_connections()	p.connections()
p.get_cpu_affinity()	p.cpu_affinity()
p.get_cpu_percent()	p.cpu_percent()
p.get_cpu_times()	p.cpu_times()
p.get_ext_memory_info()	p.memory_info_ex()
p.get_io_counters()	p.io_counters()
p.get_ionice()	p.ionice()
p.get_memory_info()	p.memory_info()
p.get_memory_maps()	p.memory_maps()
p.get_memory_percent()	p.memory_percent()
p.get_nice()	p.nice()
p.get_num_ctx_switches()	p.num_ctx_switches()
p.get_num_fds()	p.num_fds()
p.get_num_threads()	p.num_threads()
p.get_open_files()	p.open_files()
p.get_rlimit()	p.rlimit()
p.get_threads()	p.threads()
p.getcwd()	p.cwd()

All psutil.Process set_* methods lost the set_ prefix. Assuming "p = psutil.Process()":

Old name	Replacement
p.set_nice()	p.nice(value)
p.set_ionice()	p.ionice(ioclass, value=None)
p.set_cpu_affinity()	p.cpu_affinity(cpus)
p.set_rlimit()	p.rlimit(resource, limits=None)

Except for 'pid' all psutil.Process class properties have been turned into methods. This is the only case which there are no aliases. Assuming "p = psutil.Process()":

Old name	Replacement
p.name	p.name()
p.parent	p.parent()
p.ppid	p.ppid()
p.exe	p.exe()
p.cmdline	p.cmdline()
p.status	p.status()
p.uids	p.uids()
p.gids	p.gids()
p.username	p.username()
p.create_time	p.create_time()

timeout parameter of cpu_percent* functions defaults to 0.0 instead of 0.1.
long deprecated psutil.error module is gone; exception classes now live in "psutil" namespace only.
Process instances' "retcode" attribute returned by psutil.wait_procs() has been renamed to "returncode" for consistency with subprocess.Popen.

Enhancements

4: FreeBSD support for all functions of psutil
9: Process.uid and Process.gid now retrieve process UID and GID.
11: Support for parent/ppid - Process.parent property returns a Process object representing the parent process, and Process.ppid returns the parent PID.
12 & 15: NoSuchProcess exception now raised when creating an object for a nonexistent process, or when retrieving information about a process that has gone away.
21: AccessDenied exception created for raising access denied errors from OSError or WindowsError on individual platforms.
26: psutil.process_iter() function to iterate over processes as Process objects with a generator.
Process objects can now also be compared with == operator for equality (PID, name, command line are compared).

Bug fixes

17: get_process_list() ignores NoSuchProcess and AccessDenied exceptions during building of the list.
22: [Windows] Process(0).kill() was failing with an unset exception.
23: Special case for pid_exists(0)
24: [Windows] Process(0).kill() now raises AccessDenied exception instead of WindowsError.
30: psutil.get_pid_list() was returning two ins
