Changelog

5.3.0

=====

Enhancements

• 802_: disk_io_counters() and net_io_counters() numbers no longer wrap
  (restart from 0). Introduced a new "nowrap" argument.
• 1015_: swap_memory() now relies on /proc/meminfo instead of sysinfo() syscall
  so that it can be used in conjunction with PROCFS_PATH in order to retrieve
  memory info about Linux containers such as Docker and Heroku.
• 1022_: psutil.users() provides a new "pid" field.
• 1025_: process_iter() accepts two new parameters in order to invoke
  Process.as_dict(): "attrs" and "ad_value". With this you can iterate over all
  processes in one shot without needing to catch NoSuchProcess and do list/dict
  comprehensions.
• 1040_: implemented full unicode support.
• 1051_: disk_usage() on Python 3 is now able to accept bytes.
• 1058_: test suite now enables all warnings by default.

Bug fixes

• 1007_: [Windows] boot_time() can have a 1 sec fluctuation between calls; the
  value of the first call is now cached so that boot_time() always returns the
  same value if fluctuation is <= 1 second.
• 1014_: [Linux] Process class can mask legitimate ENOENT exceptions as
  NoSuchProcess.
• 1016_: disk_io_counters() raises RuntimeError on a system with no disks.
• 1017_: net_io_counters() raises RuntimeError on a system with no network
  cards installed.
• 1021_: [Linux] open_files() may erroneously raise NoSuchProcess instead of
  skipping a file which gets deleted while open files are retrieved.
• 1029_: [OSX, FreeBSD] Process.connections('unix') on Python 3 doesn't
  properly handle unicode paths and may raise UnicodeDecodeError.
• 1033_: [OSX, FreeBSD] memory leak for net_connections() and
  Process.connections() when retrieving UNIX sockets (kind='unix').
• 1040_: fixed many unicode related issues such as UnicodeDecodeError on
  Python 3 + UNIX and invalid encoded data on Windows.
• 1046_: [Windows] disk_partitions() on Windows overrides user's SetErrorMode.
• 1047_: [Windows] Process username(): memory leak in case exception is thrown.
• 1048_: [Windows] users()'s host field report an invalid IP address.
• 1058_: fixed Python warnings.

Porting notes

• 1039_: returned types consolidation:
• Windows / Process.cpu_times(): fields 3 and 4 were int instead of float
• Linux / FreeBSD: connections('unix'): raddr is now set to "" instead of
  None
• OpenBSD: connections('unix'): laddr and raddr are now set to "" instead of
  None
• 1040_: all strings are encoded by using OS fs encoding.
• 1040_: the following Windows APIs returned unicode and now they return str:
• Process.memory_maps().path
• WindosService.bin_path()
• WindosService.description()
• WindosService.display_name()
• WindosService.username()
• 1046_: [Windows] disk_partitions() on Windows overrides user's SetErrorMode.
• 1047_: [Windows] Process username(): memory leak in case exception is thrown.
• 1050_: [Windows] Process.memory_maps memory() leaks memory.
