[Digikam-devel] [svn-0.9] IE sub process not killed when IE window is closed.

Another small bug in current SVN:

Clicking on a thumbnail starts the IE and if a raw file is involved also a
dcraw sub process. If I now immediately close the IE the sub process still
runs.

Bye

I remember that there is a pending task about this subject in
Digikam::DImg::RawLoader implementation. Marcel, your viewpoint ?

The process is created with popen and closed with pclose. However, pclose does
not kill the process but waits for its termination.
So there is currently no support for aborting the loading of a raw file.

The discussion was about if we will move to some sort of library one day (the
freedesktop project) and then we could support aborting without problems.

We might want to port the code to KProcess, which we can kill. I don't know if
there are any good reasons for using popen.

No Marcel there is no technical reasons, excepted perhaps the performances
about process creation.

I have just used popen like gimp raw plugin does. I'm agree with you, KProcess
will certainly better (like krita Raw loader does).
