Remove time adjustment; instead warn if peer clocks are too different
The policy is: warn if we have seen at least 8 (TIMEDATA_WARNING_SAMPLES) peer times, in the version messages of the first 20 (TIMEDATA_MAX_SAMPLES) unique (by IP address) peers that connect, that are more than 10 minutes (TIMEDATA_WARNING_THRESHOLD seconds) but less than 10 days (TIMEDATA_IGNORE_THRESHOLD seconds) away from local time.
fixes#4338
Allow negative heights in RPC calls
For issue https://github.com/zcash/zcash/issues/2197
Currently adding the feature to `getblock` and `getblockhash`. There is another candidate: `getblocksubsidy` however i want to have some review about these 2 first before repeating what could be a bad approach.
Initialize ThreadNotifyWallets before additional blocks are imported
The intention of this PR is to address #4301. It seems `ThreadNotifyWallets` assumes that `chainActive.Tip()` on initialization reflects the wallet's view of the active tip, but prior to `ThreadNotifyWallets`'s initialization the active chain ends up being modified by blocks that are imported from disk, so our local `pindexLastTip` ends up out of sync with the wallet's actual "last" tip.
This PR moves the initialization of `ThreadNotifyWallets` to earlier in the process while passing in the current active tip. This addresses the problem for non-fresh nodes, and then for fresh nodes we have the notification thread wait until the genesis block has been loaded.
Change cm to cmu in sapling
Part of https://github.com/zcash/zcash/issues/3446
For each of the 2 commits, suggested change was made, then fixed build errors until compile. Finally ran bitcoin and gtests, both of them passing.
zcutil/fetch-params.sh unneeded --testnet arg should warn user
If fetch-params.sh user doesn't know that testnet and mainnet params are the same, and user specifies --testnet, it's confusing that the argument is ignored.
Upstream PRs relating to strMiscWarning
This pulls in upstream PRs bitcoin/bitcoin#7114 and bitcoin/bitcoin#9236 (non-QT parts).
* Fixesbitcoin/bitcoin#6809 - run-of-the-mill exceptions should not get into `strMiscWarning` (which is reported by `getinfo`).
* Eliminate data races for `strMiscWarning` and `fLargeWork*Found`. This moves all access to these data structures through accessor functions and protects them with a lock.
