Hmm ... you should NEVER call hook_install from inside a hook_update_N. (This is because the behaviour of hook_install may change in a later update, and potentially people could try updating both hook_update_N steps at once. hook_update_N should bring the database up to the state it needs to be at the time it was written, not whatever the current state happens to be.)
That said - the above is unrelated to this error, which can probably be resolved simply by adding a
return array()(see hook_update_N() documentation). For preference, the array should be populated via update_sql() calls ... one for each query, so people know what's going wrong (if applicable).Taking all of this into account, the hook should look something like this:
<?phpfunction taxonomy_context_update_2() {
$ret = array();
$ret[] = update_sql("DROP TABLE IF EXISTS {taxonomy_context_vocabulary}");
$ret[] = update_sql("DROP TABLE IF EXISTS {taxonomy_context_term}");
$ret[] = update_sql("DROP TABLE IF EXISTS {taxonomy_context}");
$ret[] = update_sql("CREATE TABLE {taxonomy_context} (
id int(10) unsigned NOT NULL default 'term',
type enum ('vocabulary', 'term') NOT NULL default 'term',
format int(4) NOT NULL default 0,
KEY (id, type)
) /*!40100 DEFAULT CHARACTER SET UTF8 */");
return $ret;
}
?>
Obviously for best practice you'd include a
switch ($GLOBALS['db_type']) { }block, but life's too short.#2
One more thing: for best best practice, you'd be copying all of the data from the old tables into the new one. This is supposed to be a seamless update, after all - an alternative to uninstalling and reinstalling.

This is not a problem for the 6.x release. If someone wants to back-port a fix to 5.x, re-open this issue with a patch.
