windows: go tool pprof

[nsf]

Well, since pprof is actually a perl script. It just doesn't work on windows. "go
tool" assumes that every tool ends with the ".exe" suffix on microsoft
operating system and pprof isn't.

Perhaps it should be removed from tool directory on windows at all? It's under
"misc" anyways, if someone really wants to use it with mingw or cygwin
environment it is possible to do.

Or perhaps there is some other way to make it work.

Comment 1:

I use linux to build windows programs. So I use pprof on linux to inspect my profiles.
Perhaps, it does work with mingw. I do not know. Leaving for others to decide what to do.

Labels changed: added os-windows.

Comment 2 by reddooots:

I played around with pprof a bit tonight and it works for the most part under msys.
Problem #1:
The web commands can't find a web browser.  The only work around I could find was
opening the output of the web commands yourself.
Problem #2:
The list commands do not work, go tool objdump stops responding and then windows kills
objdump.  The easiest fix I found was copying pprof into the same directory as the exe
and profile.
Also tried using strawberry perl to run pprof via the command prompt.
Here is the output.
C:\Users\Jared\go\src\test>perl pprof test.test.exe out.raw

I use whatever perl comes with mingw:

Comment 6 by reddooots:

Oh I didn't even think to try it with msys this time.
Seems to work for me, do you know how to get the web commands to open up a browser?

Comment 7 by reddooots:

Got the browser working, after a little searching and it turns out ln -s just copies the
target in msys instead of making a symlink.  So instead of making
/etc/alternatives/gnome-www-browser a symlink I made it a bash script that opens the
browser.
#!/bin/bash
chrome $1
With that web, weblist, list, and top commands all work for me in msys.
