The t# and w# formats were not correctly handled. Will backport. ........ r59242 | christian.heimes | 2007-11-30 22:11:28 +0100 (Fri, 30 Nov 2007) | 3 lines Fix for feature request #1528 Add os.fchmod Georg Brandl has added fchmod() and fchown(). I've contributed lchown but I'm not able to test it on Linux. However it should be available on Mac and some other flavors of Unix. I've made a quick test of fchmod() and fchown() on my system. They are working as expected. ........
