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 `rand.Read` has been replaced by `crypto/rand`.`Read` in this PR.	2 years ago

Andrey Petrov	46ec63b849	ethdb/dbtest: addd test suite for ethdb backends (#19960) ... - Move the existing tests from memorydb into a generalized testsuite that can be run by any ethdb backend implementation. - Add several more test cases to clarify some non-obvious nuances when implementing a custom ethdb backend, such as the behaviour of NewIteratorWithPrefix vs NewIteratorWithStart. - Add leveldb to the testsuite using in-memory storage for fast execution.	6 years ago
