* Removed some Windows specific unit test annoyances
details:
+ Short put()/get() cycles on persistent database have a race condition
with vendor rocksdb. On a specific (and slow) qemu/win7 a 50ms `sleep()`
in between will mostly do the job (i.e. unless heavy CPU load.) This
issue was not observed on github/ci.
+ Removed annoyances when qemu/Win7 keeps the rocksdb database files
locked even after closing the db. The problem is solved by strictly
using fresh names for each test. No assumption made to be able to
properly clean up. This issue was not observed on github/ci.
* Silence some compiler gossip -- part 7, misc/non(sync or graphql)
details:
Adding some missing exception annotation
* Silence some compiler gossip -- part 5, common
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Silence some compiler gossip -- part 6, db, rpc, utils
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Silence some compiler gossip -- part 7, randomly collected source files
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Silence some compiler gossip -- part 8, assorted tests
details:
Mostly removing redundant imports and `Defect` tracer after switch
to nim 1.6
* Clique update
why:
More impossible exceptions (undoes temporary fix from previous PR)
* Simplify pivot update
why:
No need to fetch the pivot header from the network when it can be
be made available in the ivot cache
also:
Keep `txPool` update disabled while syncing
* Cosmetics, tune down some logging noise
* Support `snap/1` without `eth/6?`
why:
Eth is not needed here.
* Snap is an (optional) extension of `eth`
so:
It it must be supported somehow. Nevertheless it will be currently
unused in the snap syncer.
* Register external beacon stream header
why:
This will be used to sync the peers against.
* Update total coverage book-keeping for 100% roll-over
details:
Provide commonly available/used function
* Replace best pivot by beacon stream tracker
details:
Beacon stream header cache will be updated by external chain monitor via
RPC. This cached header will then be used to sync the pivot.
