ID 228162 - Batch rendering fails if .katana directory cannot be created

Problem summary

In interactive mode, Katana needs write access to the user's home directory in order to create a '.katana' directory. In batch mode, this should not be a requirement.

Before 2.5, Katana logged a warning during batch rendering if '.katana' could not be created. In 2.5+, Katana prints an exception after the warning and exits.

Reproduction steps

These reproduction steps apply to Linux.

1. Create a fake home directory: mkdir /tmp/fakehome
2. Make the fake home directory read-only: chmod -w /tmp/fakehome

3. Launch Katana with the fake home directory assigned to the HOME environment variable:

   HOME=/tmp/fakehome $KATANA_ROOT/katana --batch --asset $KATANA_ROOT/demos/katana_files/aovs_prman.katana -t 1

   • Expected: Katana prints a warning ('[WARN python.PyUtilModule.ResourceFiles]: Unable to create user .katana directory') but renders successfully
   • Actual: Katana prints a warning, then prints an exception and exits
