Re: Running tasklist /m in cygwin hangs

Greetings, Marco Atzeri!

I can confirm it still hangs for me with 1.7.35. I am using the 32 bit (i686) Cygwin which is the only difference from Andrey's.


on  $ uname -vrsm
CYGWIN_NT-6.1-WOW 1.7.35(0.287/5/3) 2015-03-04 12:07 i686

It is only a bit slow (both mintty and console)

$ time tasklist /m normaliz.DLL

Oh... wow...

It seems some type of timeout in the interaction of this
windows utility and cygwin

Was it native console or pty ?


on 32bit cygwin on 64bit W7
cmd+bash and mintty+bash have the same long time.

As the effect is around 10 sec per line and "tasklist.exe" is looking
which process is using a certain dll, I presume that there is a negative
interactions (timeout, double sleep ?).

cmd alone or 64 bit cygwin has no delay effect.

However on 64bit you can compare

/cygdrive/c/windows/SysWOW64/tasklist.exe /m normaliz.dll
/cygdrive/c/windows/System32/tasklist.exe /m normaliz.dll

timing ;-)
