Currently Writable accepts trait Write as a type parameter but Readable
takes Read as a trait object, which is not symmetrical and also less performant. This PR changes Readable trait and all places where it's used
Currently we pass a Vec. This requires an extra allocation and copy of all elements if a caller doesn't have a Vec already, which is at least 95% of cases.
Another, a smaller issue, we have a function util::to_hex and some structs implement to_hex() on top of it, so we have a mix of it in the code. This PR introduces a trait and a blanket impl for AsRef<[u8]> which brings a uniform API (obj.to_hex()). One unfortunate case is arrays of size bigger than 32 - Rust doesn't implement AsRef for them so it requires an ugly hack (&array[..]).to_hex().
* no need for AsFixedBytes we can just use AsRef<[u8]>
* cleanup FixedLength trait
* revert this change for now
* fix store tests
* cleanup and fix tests after rebase
* fix tests
* update based on PR review
less hard-coded values now
* cleanup
* add 2nd HF and cuckaroom
* add cuckaroom and hardfork tests
* remove all traces of later phaseouts
* refactor header_version from valid_header_version
We use crate renaming to remove grin prefix, as result imports for util and keychain crates start with crate::
which looks like a part of the current crate. This PR fixes it.
Also some small improvements were made.
If this approach works I'll replicate it to other crates.
* Verify headers and blocks only when needed
Curretnly we have some lightweigt validation implemented as part of
entity deserialization, which is safer and allows us to not parse the
entire object if some part is invalid. At the same time this logic
always applies when we read an entity, eg when reading from DB.
This PR introduces UntrustedHeader/Block which is used when we read from
the network. It does partial validation during read, then it is supposed
to be converted into regular header/block which doesn't validate itself.
Also this PR adds "lightweight" validation to block header read like we have
for block body, so we don't parse block body if the header is invalid.
Fixes#1642
* Move version validation to untrusted header
* update fuzz tests
* Optimize POW read
This functionality is used to deserialize header (from network or from
DB), it was taking up to 40% cpu time during initial header sync. This
PR brings it down to 3-4%. Function read_number would look better as
closure, unfortunately the compliler doesn't inline it in this case, so
it would be 2x slower.

* 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'

* 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
