Installation problem with Windows Server 2008

Installation problem with Windows Server 2008

[Nimish Pachapurkar]

Hello,

I am experiencing problem with Cygwin installation on the latest
Windows Server 2008 Enterprise version RC1. I am using the latest
setup.exe from Cygwin home page (as of yesterday). The setup runs fine
during the package selection and download phase. The installation
"hangs" when it tries to run the first of the postinstall shell
scripts.

By "hang", I mean the process takes up 100% CPU for an indefinite
period of time. Even after I cancel the installation process, the bash
process keeps running. I had to kill the process using Task Manager.

I installed all the default selected packages plus Python 2.5.

When I manually start the bash.exe program by double-clicking on
"c:\cygwin\bin\bash.exe", I can use some of the commands okay (like
echo, ls, find, cat, less, etc). But again, if I invoke Python
interactive interpreter, it hangs. Interestingly, "python --version"
works fine. But "python <any-python-script>" hangs.

Is Cygwin supposed to work on Server 2008 yet? If so, are there any
known issues? I noticed that a similar problem was reported in August
on this list but did not find a solution.

Any help would be appreciated.

Thanks,

Windows 2008 Server is not yet supported.

Thanks for the clarification. Is there a plan for supporting it in near future?

I was under the impression that server 2008 is based on Vista and
Cygwin already works on Vista. Obviously, they are sufficiently
different.

As usual, new OS versions are supposed to be supported around the
time they are officially released.

I have 2K8 RC1 installed myself and I see these strange hangs, too.
There are at least three different types of hangs when running a Cygwin
process.  None of these hangs occur with non-Cygwin processes, nor do
they occur in Vista (not even in the SP1 RC1 version).  Strange enough,
these hangs occur when calling OS functions and these OS functions are
taking the CPU time, apparently.  At this point in time I hope this is
just one tiny bug in RC1 which will be fixed.

Sorry about the mail id. I will take care henceforth.

I tried a slightly older version of server 2008. I am not sure which
one it is - most likely RC0. And Cygwin works like a charm. I have no
clue what's the big difference between the two.

I tried Version 6.0 (Build 6001: Service Pack 1, v.275) and Cygwin
works. (Probably RC0)
I tried Version 6.0 (Build 6001: Service Pack 1, v.667) and Cygwin fails. (RC1)

I also think it is a bug that will hopefully go away soon. Hope this
is useful to others.

I did some more testing.

It seems that the hang problem is specific to python only. I tried the
Windows Server 2008 with Hyper V RC1 version which is a later build
than the enterprise RC1 version. The python hang persists. However,
cygwin installation with or without python goes through without a
problem. Python hangs when opening the interactive interpreter shell
or when running a python script. Commands like "python --help" work
just fine.

How could I debug it further? What tools do cygwin developers usually
use to figure out where the problem is? I tried using WinDbg but could
not make much sense out of it.

It's defintely not Python only on RC1.

I guess I should try the Hyper V version, too at one point.

It seems that Microsoft is not likely to fix anymore bugs before RTM
of Server 2008.
Is it possible to get a workaround for this issue? Or is it completely
OS-dependent?

Thanks,

It only happens on 2K8 if that's what you're asking for.  So far I don't
have any idea how to fix this problem.  The effect is really puzzeling.
