List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 26 Nov 2009 20:23:51 -0000 In order to handle message renames the following changes were deemed necessary: * Mtime check on individual files was disabled. As files may be moved around without changing their mtime, it's necessary to parse them even if they appear old in case old message was moved. mtime check on directories was kept as moving files changes mtime of directory. * If message being parsed is already found in database under different path, then this message is considered to be moved, path is updated in database and this file does not undergo further processing. Note that after applying this patch notmuch still does not handle copying files (which is harmless, database will point to the last copy of message found during 'notmuch new') and deleting files (which is more serious, as dangling entries will show up in searches).
