* add FeeFields type
* use FeeFields with ::zero and try_into().unwrap()
* fixed tests
* avoid 0 accept_base_fee
* add aggregate_fee_fields method for transaction
* implement std::fmt::Display trait for FeeFields
* make base_fee argument non-optional in libtx::mod::tx_fee
* add global and thread local accept_fee_base; use to simplify tests
* set unusually high fee base for a change
* revert to optional base fee argument; default coming from either grin-{server,wallet}.toml
* remove optional base fee argument; can be set with global::set_local_accept_fee_base instead
* define constant global::DEFAULT_ACCEPT_FEE_BASE and set global value
* add Transaction::accept_fee() method and use
* Manual (de)ser impl on FeeFields
* fix comment bug
* Serialize FeeFields as int in tx
* allow feefields: u32:into() for tests
* try adding height args everywhere
* make FeeFields shift/fee methods height dependent
* prior to hf4 feefield testing
* rename selected fee_fields back to fee for serialization compatibility
* fix test_fee_fields test, merge conflict, and doctest use of obsolete fee_fields

* first pass at peers iter cleanup
* more flexible peer with diff lookups
* PeersIter with impl Iterator
* sync against outbound peers
reorder peers filters so expensive filters come later
* filter peers by capabilities during sync
* prefer outbound peers with high total difficulty
* with_difficulty now takes a fn to allow more flexible comparisons based on difficulty
* rename peers_iter() -> iter()
* Introduce CommitOnly variant of Inputs.
Introduce CommitWrapper so we can sort commit only inputs correctly.
* rememebr to resort if converting
* write inputs based on variant and protocol version
* read and write protocol version specific inputs
* store full blocks in local db in v3
convert to v2 when relaying to v2 peers
* add debug version_str for inputs
* no assumptions about spent index sort order
* add additional version debug logs
* fix ser/deser tests for proto v3
* cleanup coinbase maturity
* rework pool to better handle v2 conversion robustly
* cleanup txpool add_to_pool
* fix nrd kernel test
* move init conversion earlier
* cleanup
* cleanup based on PR feedback
* Introduce GLOBAL_CHAIN_TYPE and make CHAIN_TYPE thread_local.
This makes testing more explicit and significantly more robust.
* set_local_chain_type() in tests
* cleanup - weird
* get pool tests working with explicit local chain_type config
* core tests working with explicit local chain_type
* p2p tests working with explicit local chain_type
* store tests working
* cleanup, feedback
We have to make an extra allocation per db get request because key generation function to_key takes Vec. Taking byte slice (AsRef<[u8]> to be precise) also simplifes the code a bit.
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
We allocate 17 vectors (in the heap) per 512 headers, this PR reduces the number to 1 by resuing the buffer for headers and eliminating the need in the vector of indices
* feat: allow DNS names in peers/seeds list and resolve them
* tests: add mod for peer tests
* refactor: rename some variables
* chore: use Serde desrialize to resolve DNS names into PeerAddrs
* fix: compile
* fix: add back code to remove duplicate ip addresses from resolved DNS seeds
* 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
Commit d3dbafa80b "Use blocking IO in P2P to reduce CPU load" (merged
into v2.1.0) introduced the constant IO_TIMEOUT, setting it to 1 second.
On nodes with high-latency connections, this short timeout causes the
txhashset archive download during step 2 of the IBD process to
invariably fail before it completes. Since there's no mechanism for
resuming a failed download, this means the node gets stuck at this stage
and never syncs.
Increasing IO_TIMEOUT to 10 seconds solves the issue on my node; others
might suggest a more optimal value for the constant.
* 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
* wip
* exhaustive match
* write with fixed v1 strategy when writing for hashing
* local protocol version is 2
* cleanup "size" tests that exercise v1 vs v2 vs default protocol versions
* add proto version to Connected! log msg
* cleanup docs
* negotiate protocol version min(local, peer) when doing hand/shake
To convert option to error we generate an error message. In some places
it contains header or block hash code or other data which is costly to
produce. So during the initial header sync we spend 12% of all time on
generating those messages (in 99% cases we don't use it). This PR
introduces a lazy generation of error messages which completely
eliminates CPU load during the header sync.
