1381		Work with DBD::SQLite's latest lock errors Work with DBD::SQLite's latest lock errors "is not unique" => "UNIQUE constraint failed". String matching is lovely.	dormando		9 years ago
1380		remove update_host_property remove update_host_property No longer used since commit ebf8a5a8dc9b4452671f7816b99583bf7934e9b1 ("Mass nuke unused code and fix most tests") in MogileFS 2.50	Eric Wong		9 years ago
1379		remove users of unreachable_fids table remove users of unreachable_fids table mark_fidid_unreachable has not been used since MogileFS 2.35 commit 53528c71ca95a04cf031c39848c38b47389d039f ("Wipe out old replication code.", r1432)	Eric Wong		9 years ago
1378		monitor: batch MySQL device table updates monitor: batch MySQL device table updates Issuing many UPDATE statements slow down monitoring on high latency connections between the monitor and DB.  Under MySQL, it is possible to do multiple UPDATEs in a single statement using CASE/WHEN syntax. We limit ourselves to 10000 devices per update for now, this should keep us comfortably under most the max_allowed_packet size of most MySQL deployments (where the default is 1M). A compatibility function is provided for SQLite and Postgres users. SQLite users are not expected to run this over high-latency NFS, and interested Postgres users should submit their own implementation.	Eric Wong		9 years ago
1377		monitor: ping parent during deferred DB updates monitor: ping parent during deferred DB updates With enough devices and high enough network latency to the DB, we bump into the watchdog timeout of 30s easily.	Eric Wong		9 years ago
1376		monitor: defer DB updates until all HTTP requests are done monitor: defer DB updates until all HTTP requests are done HTTP requests time out because we had to wait synchronously for DBI, this is very noticeable on a high-latency connection.  So avoid running synchronous code while asynchronous code (which is subject to timeouts) is running..	Eric Wong		9 years ago
1375		connection/poolable: defer expiry of timed out connections connection/poolable: defer expiry of timed out connections The timeout check may run on a socket before epoll_wait/kevent has a chance to run, giving the application no chance for any readiness callbacks to fire. This prevents timeouts in the monitor if the database is slow during synchronous UPDATE device calls (or there are just thousands of active connections).	Eric Wong		9 years ago
1374		connection/poolable: disable watch_write before retrying wri... connection/poolable: disable watch_write before retrying write Otherwise we'll end up constantly waking up when there's nothing to write.	Eric Wong		9 years ago
1373		connection/poolable: do not write before event_write connection/poolable: do not write before event_write Blindly attempting to write to a socket before a TCP connection can be established returns EAGAIN on Linux, but not on FreeBSD 8/9.  This causes Danga::Socket to error out, as it won't attempt to buffer on anything but EAGAIN on write() attempts. Now, we buffer writes explicitly after the initial socket creation and connect(), and only call Danga::Socket::write when we've established writability.  This works on Linux, too, and avoids an unnecessary syscall in most cases.
