shirou a0cf924cac Merge pull request #170 from vecmezoni/fd-close 
NewProcess does not close file descriptor
Alexander Inozemtsev f4902fae49 Properly close opened file
Shirou WAKAYAMA 6c352016d8 [net]linux: start replacing lsof. still work in progress.
Shirou WAKAYAMA 1de1357e77 [process]: add FailNow to avoid panic.
shirou 1ab11f7afd Merge pull request #167 from cgilling/cmdline_slice 
process: add CmdlineSlice function for linux + freebsd
Chris Gilling 8c186ae593 process: add CmdlineSlice for darwin + windows 
darwin will not perform correctly if there are spaces in the actual
arguments, in which case a single argument will be reported as
multple. Some CGO would be needed to get around this I think.

I couldn't find any good documentation on how windows handles
command line arguments with spaces inside the actual arguments, so
this implementation merely just splits on spaces.
shirou d6702c96bd Merge pull request #168 from cgilling/faster_linux_new_process 
process: change linux NewProcess to only stat /proc/[pid]
Chris Gilling a3bbd9e3cd process: change linux NewProcess to only stat /proc/[pid] 
Before it was doing a fillFromStatus() call which was much slower
and none of the information was needed, except by the Name() func
which now will call fillFromStatus() if p.name is not set.
Chris Gilling d098bf135f process: fix bug in CmdlineSlice where cmdline is empty 
Sometimes (at least on linux) cmdline is empty, this was causing
a panic.
Chris Gilling b8c40ac83c process: add CmdlineSlice function for linux + freebsd 
This allows for getting more exact information about each argument
especially if there are arguments that have spaces in them.

This was not implemented for darwin or for windows because they
both currently have not way of properly parsing the cmdline string.
Darwin parses the output of 'ps' which is already whitespace
segmented, and windows just has the cmdline string.

Johan Walles 4438159155 Document + add tests for for mem.VirtualMemory() 
This change changes and documents the (previously undocumented) behavior of Used
to "RAM used by programs".

We also remove the undocumented and unused Shared field of that struct.

So with this change in place, the VirtualMemoryStruct contains:
* three human-consumable fields for Total, Used and Available memory
* one human-consumable UsedPercentage field
* a number of kernel specific fields
shirou e04a02d2d7 Merge pull request #161 from walles/walles/darwin-vmperf 
Use OS calls rather than exec() to get memory stats on Darwin
Johan Walles 44f817eb8d Split mem_darwin.go into CGO and non CGO variants

Johan Walles 00504a37e3 Remove unused import
Johan Walles a6cd6f803b Use Go's built in syscall.Getpagesize()
Johan Walles 13e00c76e4 Use OS calls rather than exec() to get memory statistics 
Before this change we used to exec() various binaries to find out memory
information.

While this worked, it was awfully slow.

And if somebody would want to compute how many percent of available memory all
PIDs on the system uses, that would take almost ten seconds on my laptop with
the previous implementation.

This implementation fares a lot better, and is smaller.
Johan Walles 5771ea9465 Add Darwin specific mem.VirtualMemory() tests
Shirou WAKAYAMA 3166d41538 set LC_ALL to C in order to avoid number formatting problem.
shirou 79f021f66e Merge pull request #158 from walles/walles/darwin-memorypercent 
process: Implement MemoryPercent() for Darwin
Johan Walles 70444b571b process: Implement platform independent MemoryPercent() 
It calls mem.VirtualMemory() and process.MemoryInfo(), so on the platforms where
those work MemoryPercent() will as well.

Tested on Darwin.

Johan Walles 09fbecef59 Darwin: Remove questionable UIDs 
process.Process.uids is an array of undocumented values.

That one of them is the user that the process is running as is obvious, but what
the other two are supposed to be is AFAICT undocumented.

On Darwin, the second and third UID (out of three) seem to always be 0.

This change removes the two always-zero UIDs from the process.Process struct on
Darwin, and leaves just the one that actually identifies the user the process
is running as.
Johan Walles e3a7a45492 process.Username(): Correct user names on Darwin 
Before this change, process.Username() returned "root" for all processes on
Darwin.
