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.
• 928_: psutil.net_connections() and psutil.Process.connections() "laddr" and
  "raddr" are now named tuples.
• 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.
• 1060_: source distribution is dynamically generated so that it only includes
  relevant files.
• 1079_: [FreeBSD] net_connections()'s fd number is now being set for real
  (instead of -1). (patch by Gleb Smirnoff)
• 1091_: [SunOS] implemented Process.environ(). (patch by Oleksii Shevchuk)

Bug fixes

• 989_: [Windows] boot_time() may return a negative value.
• 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.
• 1013_: [FreeBSD] psutil.net_connections() may return incorrect PID. (patch
  by Gleb Smirnoff)
• 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.
• 1042_: [FreeBSD] psutil won't compile on FreeBSD 12.
• 1044_: [OSX] different Process methods incorrectly raise AccessDenied for
  zombie processes.
• 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.
• 1050_: [Windows] Process.memory_maps memory() leaks memory.
• 1055_: cpu_count() is no longer cached; this is useful on systems such as
  Linux where CPUs can be disabled at runtime. This also reflects on
  Process.cpu_percent() which no longer uses the cache.
• 1058_: fixed Python warnings.
• 1062_: disk_io_counters() and net_io_counters() raise TypeError if no disks
  or NICs are installed on the system.
• 1063_: [NetBSD] net_connections() may list incorrect sockets.
• 1064_: [NetBSD] swap_memory() may segfault in case of error.
• 1065_: [OpenBSD] Process.cmdline() may raise SystemError.
• 1067_: [NetBSD] Process.cmdline() leaks memory if process has terminated.
• 1069_: [FreeBSD] Process.cpu_num() may return 255 for certain kernel
  processes.
• 1071_: [Linux] cpu_freq() may raise IOError on old RedHat distros.
• 1074_: [FreeBSD] sensors_battery() raises OSError in case of no battery.
• 1075_: [Windows] net_if_addrs(): inet_ntop() return value is not checked.
• 1077_: [SunOS] net_if_addrs() shows garbage addresses on SunOS 5.10.
  (patch by Oleksii Shevchuk)
• 1077_: [SunOS] net_connections() does not work on SunOS 5.10. (patch by
  Oleksii Shevchuk)
• 1079_: [FreeBSD] net_connections() didn't list locally connected sockets.
  (patch by Gleb Smirnoff)
• 1085_: cpu_count() return value is now checked and forced to None if <= 1.
• 1087_: Process.cpu_percent() guard against cpu_count() returning None and
  assumes 1 instead.
• 1093_: [SunOS] memory_maps() shows wrong 64 bit addresses.
• 1094_: [Windows] psutil.pid_exists() may lie. Also, all process APIs relying
  on OpenProcess Windows API now check whether the PID is actually running.
• 1098_: [Windows] Process.wait() may erroneously return sooner, when the PID
  is still alive.
• 1099_: [Windows] Process.terminate() may raise AccessDenied even if the
  process already died.
• 1101_: [Linux] sensors_temperatures() may raise ENODEV.

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 on Python 2 now return a string instead of
  unicode:
• Process.memory_maps().path
• WindosService.bin_path()
• WindosService.description()
• WindosService.display_name()
• WindosService.username()
