From 3c18eb6048c156ceb71b761f120cb64c18f3c043 Mon Sep 17 00:00:00 2001 From: drh Date: Mon, 13 Jul 2009 15:52:38 +0000 Subject: [PATCH] Remove the SQLITE_CommitBusy flag. This was an attempt to block recursion on the sqlite3_commit_hook() interface. But such recursion is explicitly disallowed, so the flag is pointless.
