[dependabot-preview]

Bumps psutil from 5.2.2 to 5.6.1.

Changelog

Sourced from psutil's changelog.

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
