Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Mahadev Konar (mahadevkonar) Assigned to: Nobody/Anonymous (nobody) Summary: Patch for session conflicsts on leader and followers Initial Comment: This patch fixes the session id conflict. This uses the id of the server as the first 8 bits, system.currentmillis() last 32 bits as the next 32 bits as the initial session id. ---------------------------------------------------------------------- >Comment By: Benjamin Reed (breed) Date: 2007-12-11 16:10 Message: Logged In: YES user_id=154690 Originator: NO +1 looks good. Check in. Let's bring it up on the mailing list as well to make sure everyone is comfortable. ---------------------------------------------------------------------- Comment By: Bartlomiej Niechwiej (bartniechwiej) Date: 2007-12-11 15:59 Message: Logged In: YES user_id=1957815 Originator: NO What about System.nanoTime() instead of System.currentTimeMillis(), just to use microseconds (forget about nano precision =P) ---------------------------------------------------------------------- Comment By: Mahadev Konar (mahadevkonar) Date: 2007-12-11 15:55 Message: Logged In: YES user_id=1926680 Originator: YES you mean the rightmost 24 bits overflow? Thats true... in that case we should recalculate. let me put in the logic for that... ---------------------------------------------------------------------- Comment By: Andrew Kornev (akornev) Date: 2007-12-11 15:46 Message: Logged In: YES user_id=1926652 Originator: NO What about the case when the leftmost 24-bit overflow? At this point, to make the algorithm completely bullet proof we should recalculate the top 40 bits... What do you think? ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=1008546&aid=1848999&group_id=209147 |
