Change Details

Steps to reproduce: # edit something that's symlinked (e.g. `PrivateSettings.php`) # scap # CLI scripts will use the updated code but the web page will not, for hours at least; presumably because the symlink's timestamp did not change so HHVM uses its cached version # touching the symlink will make the webpage update Observed on the beta cluster. Scap should make sure the last-modified date of the symlink is not older than the last-modified date of the original, to prevent this.

Find the symlinks pointing to any given file 2. Modify the symlink's mtime *** This isn't even supported on some platforms *** The expectation is that you resolve the symlink and take the mtime of the target, not the symlink it's self, so hhvm is doing it wrong. *** There doesn't seem to be a native python method to modify the timestamp of a symlink *** The functionality was added to `touch` only somewhat recently * A much more productive thing to work on is eliminating symlinks - many of them are not needed.
