Cache deletion by session_id always fails

[ziba]

If caching is enabled, then in program/include/session.inc rcube_sess_destroy calls:

$DB->query("DELETE FROM " . get_table_name('cache') . " WHERE session_id=?", $key);

However, I couldn't find any place where cache.session_id is populated.

On our production systems the cache table was large enough to delay user logins by about 20 seconds while it searched through thousands of Null values.

You're right. rcube_imap::_write_cache_record() should save session_id on insert.

Fixed in r2075.
