[Curl] Cookie Database files are wrongfully getting deleted when the database is opened

• Component: Platform
• Status: RESOLVED FIXED

[Christopher Reid]

The file stat logic in CookieJarDB::checkDatabaseCorruptionAndRemoveIfNeeded is backwards causing persistence issues. The database is wrongfully deleted when opened because it thinks it's corrupted.

LGTM. I'm not sure how liberally we should be using auto or not.

Maybe auto here?

It looks like auto is used quite a bit with openFile in the FileSystem implementation files so it makes sense to use it here too.
I'll update the patch.

Should we check whether 'handle' is valid before closing?

Thanks for the review!

Ah, right now all the closeFile implementations have a check but it seems safer to have a check here too in case more functionality is added to that file.
