Detailed Description

Handle SIGINT for HTTPCache. When the cache is in use and the process is sent SIGINT, we must make sure that the cache is left in a consistent state. This includes removing the lock file, updating the index file and making sure no partially written data or meta data files exist.

[inline, virtual]

Handle SIGINT. This handler first deletes any files opened but not added to the cache index files and then calls HTTPCache::delete_instance().

Parameters:

signum

We know it is SIGINT; included here as a check and only when NDEBUG is not defined.

Returns:

Never returns.

Implements EventHandler.
