* split horizon into two explicit values for cut through and txhashset request
* let node which has 2-7 days of history be able to handle forks larger than 2 days
* add test simulate_long_fork
* add pause/resume feature on p2p for tests
* refactor the state_sync
* ignore the test case simulate_long_fork for normal Travis-CI
* refactor function check_txhashset_needed to be shared with body_sync
* fix: state TxHashsetDone should allow header sync
* deserialize capabilities dropping unknown flag bits
* add tests for capabilities deserialization
* rustfmt
* FULL_NODE needs to be handled safely for legacy nodes
Fuzz test found that we don't read IPV6 addr (as part of p2p message)
properly. The code is supposed to read 8 dwords, but [0..8] is not a
slice of 8 ints, but a slice of one Range, so we always read just one
dword
Unlike panic it doesn't call destructors (Drop) so all open transactions
are not closed. It's fine when LMDB file is open by the current process
only, but if another process keeps the same file open such transactions
will be considered alive until the second process exits. We usually have
one or more long-lived process (like `wallet listen`) which opens the
same wallet db as short-lived wallet commands. When a command fails it
calls process::exit and as result leaks a transaction.
This pr replaces such calls with an exit code return, which allows to call
all destructors before calling process::exit.
Fixes#1822
* replace cyan and yellow which not easy to read on white background
* wallet output color scheme configuration for terminal dark/white background
* use true for dark_background_color_scheme to make the default behavior same as before
* cleanup pmmrable and len()
introduce FixedLength trait with a const LEN
make Hash impl FixedLength for consistency
* rustfmt
* store tests cleanup
* rustfmt
* whats going on with those comments and rustfmt?
* be careful resetting sync_head
make sure we have the header corresponding to header_head
and that nothing is corrupted from an earlier shutdown
* add logging when resetting heads due to missing header
* Cleanup syncer and sync header (locator)
* Simplify body sync
* Remove duplicate head in locator, add greater case in close_enough
* Various sync small fixes and tuning after testing
* More close_enough tests and related minor fixes
