v6.0.0

Compare Source

================

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.
• 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.
