Windows: get environment set by subprocess

[sachin...@gmail.com]

Hi Vinay,

I am using this sarge version: vinay.sajip-sarge-8ef70d2c06b7

I want to do this:

  1) Run this batch script "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\Tools\vsvars32.bat". 

        - This script sets some ENV variables and probably some registry settings as well for Visual Studio 2012 build environment

  2) which devenv  # This should not correctly find devenv executable in Visual Studio 11.0 directory

I tried this with sarge:

   p=sarge.Pipeline('"C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\Tools\\vsvars32.bat"; which devenv')

   p.run()

'which devenv' is not able to find 'devenv'. If I run these 2 commands from cmd.exe in Windows it works fine [Note: I have cygwin installed - so 'which' command works from cmd.exe]

I guess 2 commands in Pipeline are getting executed in 2 different subprocess and that's why ENV set in 1st command is not visible in 2nd subprocess. Is my guess correct?

How do I solve this problem?

Thanks,
Sachin

Dear Sachin,

You can't - environment variables will be set in the individual child process only and not available except to it and its child processes. This behaviour is by design, so it can't be worked around. (I don't believe the registry is altered by vcvars32.bat.)

ok. Is it possible to get ENV of child process which executed 'vsvars32.bat'? Then I can pass that ENV dictionary to my next command as "env=ENV"?

Only from within the process itself or its children. This is not related to sarge - it's just how environments work.
