Martin Holst Swende	4d3525610e	all: remove deprecated uses of math.rand (#26710) ... This PR is a (superior) alternative to https://github.com/ethereum/go-ethereum/pull/26708, it handles deprecation, primarily two specific cases. `rand.Seed` is typically used in two ways - `rand.Seed(time.Now().UnixNano())` -- we seed it, just to be sure to get some random, and not always get the same thing on every run. This is not needed, with global seeding, so those are just removed. - `rand.Seed(1)` this is typically done to ensure we have a stable test. If we rely on this, we need to fix up the tests to use a deterministic prng-source. A few occurrences like this has been replaced with a proper custom source. `rand.Read` has been replaced by `crypto/rand`.`Read` in this PR.	2 years ago
Felföldi Zsolt	d96870428f	les: UDP pre-negotiation of available server capacity (#22183) ... This PR implements the first one of the "lespay" UDP queries which is already useful in itself: the capacity query. The server pool is making use of this query by doing a cheap UDP query to determine whether it is worth starting the more expensive TCP connection process.	4 years ago
Boqin Qin	be6078ad83	all: fix a bunch of inconsequential goroutine leaks (#20667) ... The leaks were mostly in unit tests, and could all be resolved by adding suitably-sized channel buffers or by restructuring the test to not send on a channel after an error has occurred. There is an unavoidable goroutine leak in Console.Interactive: when we receive a signal, the line reader cannot be unblocked and will get stuck. This leak is now documented and I've tried to make it slightly less bad by adding a one-element buffer to the output channels of the line-reading loop. Should the reader eventually awake from its blocked state (i.e. when stdin is closed), at least it won't get stuck trying to send to the interpreter loop which has quit long ago.
