QProcess and umask

**skyphyr** · 15th March 2007, 18:29

Hi All,

I've got some code which launches a program with QProcess (http://sf.net/projects/splish)

The program run by QProcess does not have the same umask settings as my Qt application does. I grab the environment with QProcess::systemEnvironment();, but I guess this is only getting the environment variables. Any idea how I ensure umask settings survive - I only saw mention of how to set them in the QProcess docs, not how to leave them alone.

Cheers,

Alan.

What exactly happens with the mask? The child process should inherit the mask.

Hi Wysota,

It's set to 0000 (I know this is a bad thing Tm) but when the application executes it does everything with 0022

Cheers,

Alan.

Meaning that you can't use/set write permissions for group and other? Could you show us the code used to set the mask and the one that tells you the mask is different than you set before?

Hi Wysota - I haven't used any code to set it - the files created had different permissions from the umask.

Will do some more investigation - it may have been the program I launched, not Qt.

Cheers,

Alan.
