This either means at least one byte received and 5 minutes have passed, or at least 500MB have been downloaded. The timer currently runs every 20 seconds. [SERVER] Support limiting alt-servers to specific namespace 2019-09-04T18:06:11+00:00 Simon Rettberg 2019-09-04T18:06:11+00:00 urn:sha1:543877c7fc17c0a881d6a85c76dfc17f8def7dff Not really namespace but simple string matching for the image path. Path is matched from start with no support for glob or regex, so usually you want to have a trailing '/' to limit to certain directories. [SERVER] Fix altservers_getListForClient() 2019-09-04T17:49:11+00:00 Simon Rettberg 2019-09-04T17:49:11+00:00 urn:sha1:778fb6d2d15d534869461560d80524d74446bb84 The score wasn't reset when adding clients to the list, resulting in exactly one server filling up the whole list. [SERVER] Get rid of alt-servers thread, per-uplink rtt history 2019-08-22T14:14:27+00:00 Simon Rettberg 2019-08-22T14:14:27+00:00 urn:sha1:5fb4ef278be86fb6bda487f65ec4855d830bf4e5 Alt-Server checks are now run using the threadpool, so we don't need a queue and dedicated thread anymore. The rtt history is now kept per uplink, so many uplinks won't overwhelm the history, making its time window very short. Also the fail counter is now split up; a global one for when the server actually isn't reachable, a local (per-uplink) one for when the server is reachable but doesn't serve the requested image. [SERVER] uplink: More consistent type/variable naming 2019-08-18T19:31:56+00:00 Simon Rettberg 2019-08-18T19:31:56+00:00 urn:sha1:da0950ad342bae3b40a74bf82dba6c1f82e7eb57 * Change link to uplink everywhere * dnbd3_connection_t -> dnbd3_uplink_t [SERVER] rpc: Add q=logfile, q=altservers and q=config to /query 2017-11-08T15:14:32+00:00 Simon Rettberg 2017-11-08T15:14:32+00:00 urn:sha1:01a2ebb9a402dc4c3f9183d457565685885f6fb9 [SERVER] altservers: Tweak, cleanup, refactor, rename 2017-11-07T23:16:18+00:00 Simon Rettberg 2017-11-07T23:16:18+00:00 urn:sha1:abb54ea3342748b7c4589cd12a821957e1b58238 [SERVER] Use stdbool.h for booleans; minor refactoring of variable and function names 2014-12-31T22:39:21+00:00 Simon Rettberg 2014-12-31T22:39:21+00:00 urn:sha1:6788efa3459b9581b1e4197e37f504d8fb2e8e87 [SERVER] Improve replication and reconnecting behaviour 2014-12-22T18:46:42+00:00 Simon Rettberg 2014-12-22T18:46:42+00:00 urn:sha1:47c28e25055cfa3c4c37035cc7888d0b87392dc1 Improve uplink handling, add code to debug thread creation/destruction, change stupid convention of freeDiskSpace returning 0 on error, which is ambiguous to the disk simply being full... 2014-06-16T17:24:17+00:00 Simon Rettberg 2014-06-16T17:24:17+00:00 urn:sha1:49f9218d330f5842fe24bce79267bd2c5b239df3
