* Don't wait for p2p-server thread (#2917)
Currently p2p.stop() stops and wait for all peers to exit, that's
basically all we need. However we also run a TCP listener in this thread
which is blocked on `accept` most of the time. We do an attempt to stop
it but it would work only if we get an incoming connection during the
shutdown, which is a week guarantee.
This fix remove joining to p2p-server thread, it stops all peers and
makes an attempt to stop the listener.
Fixes [#2906]
* rustfmt
* introduce HeaderVersion (was u16) for type safety
cleanup pow ser/deser (version unused)
* fixup tests for HeaderVersion
* validate header version during header deserialization
* Add hooks for network and chain events. Move logging to an EventLogger
* implement webhooks
* fix failing test
* remove unnecessary 'pub'
* add some metadata to the json payload
* avoid unecessary init
* resolve conflicts
* chore: replace trim_right with $ sed -i'' 's/trim_right/trim_end/' **/*.rs
* docs: individually document macros to avoid warning, add TODO to make to_edge hygenic
* docs: document impl_array_newtype macros, refactor: move all impl_array_newtype macro traits into impl_array_netype_index
* Cuckatoo size shift upgrade schedule
* Move the schedule into graph_weight instead of messing with min edge bits
* Cleanup and fixes now that we have an agreed upon schedule
* PoW context is now properly picked depending on the chain type,
edge bits and block height. Height const for T4 hard fork leaving
a couple weeks to have miners in place. Removed now unused Cuckoo context.
* Simplified block siphash
* Fix servers crate compilation
* Tiny bit cleaner block siphash. Maybe.
* Cuckatoo min edge bits update for T4 and mainnet
* Fix header size tests, Cuckatoo31 default means one more bit per edge
* Remove redundant param from verify_size
* First pass at iterative siphash
* Generalizing our siphash24 implementation slightly to make it friendlier to repeated hashing
* Block siphash algorithm, Cuckaroo placeholder
* Cuckaroo validator, still needs to be tested with vectors from the @tromp implementation
* Working cuckaroo validation with test vectors for cuckaroo19, will add cuckaroo29 vectors when a lean or mean implementation can find some solutions
* use FixedLength to define serialized size in bytes of various structs
replace usages of mem::size_of() with ::LEN so we correctly calculate serialized sizes in bytes
* rustfmt
* First pass at secondary proof of work difficulty adjustments
* Core and chain test fixes
* Next difficulty calc now needs a height. Scaling calculation fixes. Setting scaling on mined block.
* Change factor to u32 instead of u64.
* Cleanup structs used by next_difficulty
* Fix header size calc with u32 scaling
* cuck placeholder
* rustfmt
* cuckatoo, early days
* rustfmt
* data structures are in place, siphash key creation is consistent with @tromp
* solver in place, (not yet working)
* cuckatoo test solver working with test nonce
* rustfmt
* update solver to remove adjacency list removals
* verifier functioning
* rustfmt
* Proper error handing in Cuckatoo module, couple of tests
* modify cuckoo/cuckatoo solvers and verifiers to function identically, in advance of trait refactoring
* rustfmt
* refactor PoW context into trait, default to using cuckoo context
* rustfmt
* create macros for integer casting/unwraps
* don't instantiate structs when just verifying, add test validation vector for cuckatoo 29
* rustfmt
* don't init cuckoo structs if just validating
* test fix
* ensure BH hashing for POW is only done within miner/validators
* 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
* improve: time crate flagged as deprecated, switch to actively maintained chrono crate
* improve: complete the switching from deprecated time crate to chrono crate, for all the tests part
* improve: complete switching to chrono crate, for the left tests in 'chain' and 'wallet'
* Added sizeshift to proof of work and encoding as VLQ
* Fix some loose ends to get things to compile
* Rename sizehift to min_sizeshift
* Pipeline checks for PoW Cuckoo Cycle size shift and adjustment
factor before difficulty comparison.
* Working delta+VLQ encoding of u64 PoW, unfortunately still a
little larger than u32, at least for Cuckoo30.
* Changed binary encoding of proof of work to a sequence of exact
compact bit representation of each nonce. Somewhat simpler,
shorter and matches the data to be hashed.
* Few fixes based on @tromp feedback:
* Max nonce is 2^(N-1)
* Need a separate constant for reference sizeshift
* Cuckoo implementation now conserves sizeshift. Test providing a
block at higher sizeshift.
* Last small overflow protection
