* replace header_by_height index with reads into the header MMR
* rustfmt
* cleanup
* cleanup chain tests
* fix locate_headers to stop on our max header
* fix the deadlock in comact_blocks_db...
* cleanup and docs/comments
* block_accepted via adapter is now reorg aware
we skip reconciling the txpool is block is not most work
we skip reconciling the reorg_cache is not a reorg
* rustfmt
* logging tweaks
* rework block_accepted interface
* rustfmt
* rework reorg determination
* introduce BlockStatus to represent next vs reorg vs fork
* rustfmt
* cleanup logging
* log from adapter, even during sync
* Replace logging backend to flexi-logger and add log rotation
* Changed flexi_logger to log4rs
* Disable logging level filtering in Root logger
* Support different logging levels for file and stdout
* Don't log messages from modules other than Grin-related
* Fix formatting
* Place backed up compressed log copies into log file directory
* Increase default log file size to 16 MiB
* Add comment to config file on log_max_size option
* get rid of RwLock around peer instances
* rustfmt
* rename stuff to live_info
* rustfmt
* serialize into PeerInfoDisplay
limit live_info write lock to peer_info.update()
rename to PeerLiveInfo
* simplify broadcast logic a bit more
connected peers are connected by definition
* return true/false on broadcast so we can send to more peers
* rustfmt
* fix p2p and server tests for PeerInfoDisplay
* commit
* Go back to db for head and header_head
* Use batch consistently for db access
* Pass active txhashset and batch in the ctx
* Only update head in db if total work increases
* Only updated header_head if total work (on header chain) increases
* Move Proof and Difficulty types to pow module. Difficulty scaling calculation.
* Diffculty scaling and size shift for 2nd PoW
* Backport e7eb26ee
* Test compilation fixes
* Scaling only need to go one way, as @tromp pointed out
* Local test container used different folder than regular server, so test could not find txhashset files
* Error stacktrace was printed in cases when error was expected, which created some noise and confusion
* fix: in case txhashset validation fail, 'TxHashsetDownload' should retry (#1293)
And add 2 more fixes:
1. handle sending request failure of 'send_txhashset_request';
2. use a 10-mins timeout to handle noresponse failure, in case a peer ignore our txhashset request, or in case a peer fail to send a file for some reason.
* Remove now unnecessary txhashset write lock
* Ring buffer of hashes the chain has already processed
* Specifically report too old blocks as peer should be banned
* Move sync check for block relay, clean TODO
* No use processing transactions when syncing
* Ignore blocks older than horizon in pruning nodes
