Changelog

5.6.2

=====

2019-04-26

**Enhancements**

- 604_: [UNIX, Windows] add new psutil.getloadavg() returning system load
- 1404_: [Linux] cpu_count(logical=False) uses a second method (read from
`/sys/devices/system/cpu/cpu[0-9]/topology/core_id`) in order to determine
the number of physical CPUs in case /proc/cpuinfo does not provide this info.
- 1458_: provide coloured test output. Also show failures on KeyboardInterrupt.
- 1464_: various docfixes (always point to python3 doc, fix links, etc.).
- 1473_: [Windows] process IO priority (ionice()) values are now exposed as 4
new constants: IOPRIO_VERYLOW, IOPRIO_LOW, IOPRIO_NORMAL, IOPRIO_HIGH.
Also it was not possible to set high I/O priority (not it is).
- 1478_: add make command to re-run tests failed on last run.
average calculation. (patch by Ammar Askar)

**Bug fixes**

- 1223_: [Windows] boot_time() may return value on Windows XP.
- 1456_: [Linux] cpu_freq() returns None instead of 0.0 when min/max not
available (patch by Alex Manuskin)
- 1462_: [Linux] (tests) make  tests invariant to LANG setting (patch by
- 1463_: cpu_distribution.py script was broken.
Benjamin Drung)
- 1470_: [Linux] disk_partitions(): fix corner case when /etc/mtab doesn't
exist.  (patch by Cedric Lamoriniere)
- 1471_: [SunOS] Process name() and cmdline() can return SystemError.  (patch
by Daniel Beer)
- 1472_: [Linux] cpu_freq() does not return all CPUs on Rasbperry pi 3.
- 1474_: fix formatting of psutil.tests() which mimicks 'ps aux' output.
- 1475_: [Windows] OSError.winerror attribute wasn't properly checked resuling
in WindowsError being raised instead of AccessDenied.
- 1477_: [Windows] wrong or absent error handling for private NTSTATUS Windows
APIs. Different process methods were affected by this.
- 1480_: [Windows] psutil.cpu_count(logical=False) could cause a crash due to
fixed read violation.  (patch by Samer Masterson)
- 1486_: [AIX, SunOS] AttributeError when interacting with Process methods
involved into oneshot() context.
- 1491_: [SunOS] net_if_addrs(): free() ifap struct on error.  (patch by
Agnewee)
- 1493_: [Linux] cpu_freq(): handle the case where
/sys/devices/system/cpu/cpufreq/ exists but is empty.

5.6.1

=====

2019-03-11

**Bug fixes**

- 1329_: [AIX] psutil doesn't compile on AIX 6.1.  (patch by Arnon Yaari)
- 1448_: [Windows] crash on import due to rtlIpv6AddressToStringA not available
on Wine.
- 1451_: [Windows] Process.memory_full_info() segfaults. NtQueryVirtualMemory
is now used instead of QueryWorkingSet to calculate USS memory.

5.6.0

=====

2019-03-05

**Enhancements**

- 1379_: [Windows] Process suspend() and resume() now use NtSuspendProcess
and NtResumeProcess instead of stopping/resuming all threads of a process.
This is faster and more reliable (aka this is what ProcessHacker does).
- 1420_: [Windows] in case of exception disk_usage() now also shows the path
name.
- 1422_: [Windows] Windows APIs requiring to be dynamically loaded from DLL
libraries are now loaded only once on startup (instead of on per function
call) significantly speeding up different functions and methods.
- 1426_: [Windows] PAGESIZE and number of processors is now calculated on
startup.
- 1428_: in case of error, the traceback message now shows the underlying C
function called which failed.
- 1433_: new Process.parents() method.  (idea by Ghislain Le Meur)
- 1437_: pids() are returned in sorted order.
- 1442_: python3 is now the default interpreter used by Makefile.

**Bug fixes**

- 1353_: process_iter() is now thread safe (it rarely raised TypeError).
- 1394_: [Windows] Process name() and exe() may erroneously return "Registry".
QueryFullProcessImageNameW is now used instead of GetProcessImageFileNameW
in order to prevent that.
- 1411_: [BSD] lack of Py_DECREF could cause segmentation fault on process
instantiation.
- 1419_: [Windows] Process.environ() raises NotImplementedError when querying
a 64-bit process in 32-bit-WoW mode. Now it raises AccessDenied.
- 1427_: [OSX] Process cmdline() and environ() may erroneously raise OSError
on failed malloc().
- 1429_: [Windows] SE DEBUG was not properly set for current process. It is
now, and it should result in less AccessDenied exceptions for low-pid
processes.
- 1432_: [Windows] Process.memory_info_ex()'s USS memory is miscalculated
because we're not using the actual system PAGESIZE.
- 1439_: [NetBSD] Process.connections() may return incomplete results if using
oneshot().
- 1447_: original exception wasn't turned into NSP/AD exceptions when using
Process.oneshot() ctx manager.

**Incompatible API changes**

- 1291_: [OSX] Process.memory_maps() was removed because inherently broken
(segfault) for years.

5.5.1

=====

2019-02-15

**Enhancements**

- 1348_: [Windows] on Windows >= 8.1 if Process.cmdline() fails due to
ERROR_ACCESS_DENIED attempt using NtQueryInformationProcess +
ProcessCommandLineInformation. (patch by EccoTheFlintstone)

**Bug fixes**

- 1394_: [Windows] Process.exe() returns "[Error 0] The operation completed
successfully" when Python process runs in "Virtual Secure Mode".
- 1402_: psutil exceptions' repr() show the internal private module path.
- 1408_: [AIX] psutil won't compile on AIX 7.1 due to missing header.  (patch
by Arnon Yaari)
