2024-06-18
Enhancements
maxfileandmaxpathfields were removed from the namedtuplereturned by
disk_partitions()_. Reason: on network filesystems (NFS) thiscan potentially take a very long time to complete.
process_iter()_ no longer pre-emptively checks whether PIDs havebeen reused. This makes
process_iter()_ around 20x times faster.psutil.process_iter.cache_clear()API can be used the clearprocess_iter()_ internal cache.Process.connections()_ was renamed toProcess.net_connections()_.The old name is still available, but it's deprecated (triggers a
DeprecationWarning) and will be removed in the future.Bug fixes
Process.cmdline()_ sometimes fail with EBUSY. It usuallyhappens 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.

pid_exists()_ disagrees withProcess_ onwhether a pid exists when ERROR_ACCESS_DENIED.
pid_exists()_ erroneously return True if the argument isa thread ID (TID) instead of a PID (process ID).
MNT_constants.
Porting notes
Version 6.0.0 introduces some changes which affect backward compatibility:
disk_partitions()_' no longer hasmaxfileandmaxpathfields.process_iter()_ no longer pre-emptively checks whether PIDs havebeen reused. If you want to check for PID reusage you are supposed to use
Process.is_running()_ against the yieldedProcess_ instances. That willalso automatically remove reused PIDs from
process_iter()_ internal cache.Process.connections()_ was renamed toProcess.net_connections()_.The old name is still available, but it's deprecated (triggers a
DeprecationWarning) and will be removed in the future.v5.9.8Compare Source

2024-01-19
Enhancements
net_connections()_ returned list in C instead ofPython, 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.
Bug fixes
net_connections()_ implementation was broken.It could either leak memory or core dump.
Process.cwd()_ will return anempty string instead of raising
NoSuchProcess_.cpu_freq()now returns fixed values forminandmaxfrequencies in all Apple Silicon chips.

2023-10-15
Enhancements
cpu_percent()_ andcpu_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 10would get the right result.
Process_ class is passed a very high PID, raiseNoSuchProcess_instead of OverflowError. (patch by Xuehai Pan)
Process.ppid()_ andProcess.parents()_.ruffPython linter instead offlake8 + isort. It's anorder of magnitude faster + it adds a ton of new code quality checks.
Bug fixes

PSUTIL_DEBUGinstead.

swap_memory()_(patch by student_2333)
bytes2human()utility function was unable to properly representnegative values.
disk_usage()_ fails on Python 3.12+. (patch byMatthieu Darbois)
Process.memory_full_info()_ may incorrectly raiseZombieProcess_ if it's determined via/proc/pid/smaps_rollup. Insteadwe now fallback on reading
/proc/pid/smaps.Process.is_running()_ erroneously returnFalsefor zombie processes, because creation time cannot be determined.ZombieProcess_ onProcess.exe(),Process.cmdline()andProcess.memory_maps()_ instead of returning a"null" value.

Process.nice()_ (set),Process.ionice(),(set),
Process.cpu_affinity()(set),Process.rlimit()_(set),
Process.parent()_.Process.threads()_ always fail with AccessDenied (also asroot).

net_connections()_ implementation was rewrittenfrom scratch:

Process.cwd()_ cannot be determined(e.g. directory no longer exists), in which case we returned either
Noneor an empty string. This was consolidated and we now return
""on allplatforms.

Process.name()_ (15 chars), don't fail withZombieProcess_when we try to guess the full name from the
Process.cmdline()_. Justreturn the truncated name.
OpenBSD platforms (python 3 only).
Bug fixes
net_connections()_ returns duplicate entries."MemAvailable"field from/proc/meminforeturns0(possibly a kernel bug), in which case wecalculate an approximation for
availablememory which matches "free"CLI utility.
disk_partitions(): do not unnecessarily read/proc/filesystems and raise
AccessDeniedunless user specifiedall=Falseargument.
Matthieu Darbois)
users()_ loses precision forstartedattribute (off by1 minute).
NoSuchProcess_ may be raised instead ofZombieProcess_.virtual_memory()_ is higher than total.virtual_memory()_ metrics are wrong: available andused are too high. We now match values shown by htop CLI utility.
Process.num_threads()_ andProcess.threads()_ returnthreads that are already terminated.
Process.cwd()_ may raiseFileNotFoundErrorif cwd no longer exists. Return an empty string instead.
