#27838 closed defect (bug) (invalid)

wp-admin/setup-config.php uses is_writable rather than win_is_writable

We've been compensating for this one during our packaging process for apparently a really long time - the install process mistakenly thinks it can't write wp-config.php on CIFS and windows (depending on underlying configuration) due to setup-config.php using is_writable instead of win_is_writable, which compensates for the weird behavior.

Thanks for the patch israelshirk!

WordPress has its own handy function we can use instead - wp_is_writable(). I'm not sure why it's not used everywhere we use is_writable().

Actually, the wp_is_writable suffers from the same issue on CIFS filesystems (specifically iPage, FatCow, ...) - their permissions mechanisms resemble Windows as far as PHP is concerned, but are still on Linux, so the os check in wp_is_writable doesn't catch it. Which, now that I'm looking at wp_is_writable, may have far-reaching implications. :/

As far as we've found, the only good indicator as to whether it's writable is to try like win_is_writable does.
