Target version:
ruby -v:
ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-linux]



under the new Windows 10 Subsystem for Linux, tmpdir.rb throws Errors, because of the "if stat.world_writable? and !stat.sticky?" check. Under Windows 10, all directories are mode 777 by default. However, directory permissions are still enforced by other parts of the OS, unseen by the Linux subsystem. That means there is little sense in checking for the sticky bit in the new Windows subsystem.

This causes problems in Bundler, for example. See here:

The workaround is adding a sticky bit to the offending directories.

I am no expert in this but could you introduce an additional check so that it just ignores Microsofts strange directory modes when run under Windows 10 Subsystem for Linux?

most probably a lot of other things besides Ruby will fail miserably, so they will have to fix that in Windows itself.

  • Status changed from Open to Third Party's Issue

Thank you for reporting with the essential information "on Windows Subsystem for Linux".

Unless special condition, such issues are considered issues of Windows Subsystem for Linux.
Such a real world compatibility problem will help them ;-)
