| * | eth/downloader: fetch data proportionally to peer capacity | Péter Szilágyi | 2015-11-19 | 1 | -104/+74 |

| * | eth/downloader: also drain stateCh, receiptCh in eth/61 mode | Felix Lange | 2015-11-19 | 1 | -71/+77 |
| | | | | | | | | | | State and receipt deliveries from a previous eth/62+ sync can hang if the downloader has moved on to syncing with eth/61. Fix this by also draining the eth/63 channels while waiting for eth/61 data. A nicer solution would be to take care of the channels in a central place, but that would involve a major rewrite. | ||||
| * | eth/downloader: don't hang for spurious deliveries | Felix Lange | 2015-11-19 | 1 | -105/+57 |
| | | | | | | | | | | | | | | | | | Unexpected deliveries could block indefinitely if they arrived at the right time. The fix is to ensure that the cancellation channel is always closed when the sync ends, unblocking any deliveries. Also remove the atomic check for whether a sync is currently running because it doesn't help and can be misleading. Cancelling always seems to break the tests though. The downloader spawned d.process whenever new data arrived, making it somewhat hard to track when block processing was actually done. Fix this by running d.process in a dedicated goroutine that is tied to the lifecycle of the sync. d.process gets notified of new work by the queue instead of being invoked all the time. This removes a ton of weird workaround code, including a hairy use of atomic CAS. | ||||
