* Scaling only need to go one way, as @tromp pointed out
* Migrate main node store to LMDB
In preparation to using LMDB as a wallet database, migrate the
node db. There's no point in having 2 key-value stores.
In addition LMDB provides a few advantages as a node db, namely a
much faster build (compared to RocksDb), lesser dependencies and
transactions.
* Migrated p2p store to lmdb, stuff compiles
* More fixes, chain tests starting to pass
* Fixed txhashset rollback messing with block save and general batch delimitation. Chain tests passing.
* rustfmt
* LMDB max map size of 10MB isn't really workable. Half TB seems reasonable.
* Fix wallet tests
* Rather crucial commit was missing
* rustfmt
* Fixing new merged tests following lmdb changes
* rustfmt
* * Make txhashset validation read-only on fast sync to avoid having
a really long open transaction.
* Fix deadlock in new block processing, batch should always be
created within a txhashset lock (when they interact).
* Comment about batch and txhashset interlacing
* Fix store tests to use batch
* Externalize wallet config and seed
* Converted direct read access to file outputs map to an iterator
* Cleaned up and simplified wallet Backend trait:
* No more direct mutable access to internal structures (HashMap)
* Batch interface for all writes
* Remove unneeded read wrapper (read_wallet)
* rustfmt
* First (incomplete) pass at wallet LMDB backend
* Progressing on lmdb backent iml
* Added batch impl for LMDB wallet backend. Pretty much done with it, but not sure how to deal with commit (owned).
* rustfmt
* Wrapping LMDB batch around a refcell to work around borrow rules
* Compilation up to grin chain
* Add kernel commitments sum and kernel and output MMR sizes to block header
* Sum a block without including previous sums, cleanup. Blocks are now summed and validated based on their own totals and not the totals since genesis. This allows to get rid of BlockSum and simplified the setting of a new block's roots, kernel sum and MMR sizes. Fixes#116
* Additional kernel MMR validation to check all prior header roots successively
* Wallet tests fix
* First pass at restructuring the keychain crate and introducing a Keychain trait
* Parameterized everything that had to. Stuff compiles.
* More stuff compiles, fix most tests
* Big merge, pushing down opening the keychain forced adding factory methods on trait
* Test fixes for pool and servers crate
Small refactoring of one folder, if it makes sense I could extend the scope.
* Remove some cloning (real and just verbosity in the code)
* Naming conventions like to/into*
* Some Clippy's suggestions
I found that we don't use field init shorthand syntax, so I didn't touch this part, was it discussed before?
* verify a tx like we verify a block (experimental)
* first minimal_pool test up and running but not testing what we need to
* rework tx_pool validation to use txhashset extension
* minimal tx pool wired up but rough
* works locally (rough statew though)
delete "legacy" pool and graph code
* rework the new pool into TransactionPool and Pool impls
* rework pool to store pool entries
with associated timer and source etc.
* all_transactions
* extra_txs so we can validate stempool against existing txpool
* rework reconcile_block
* txhashset apply_raw_tx can now rewind to a checkpoint (prev raw tx)
* wip - txhashset tx tests
* more flexible rewind on MMRs
* add tests to cover apply_raw_txs on txhashset extension
* add_to_stempool and add_to_txpool
* deaggregate multi kernel tx when adding to txpoool
* handle freshness in stempool
handle propagation of stempool txs via dandelion monitor
* patience timer and fluff if we cannot propagate
to next relay
* aggregate and fluff stempool is we have no relay
* refactor coinbase maturity
* rewrote basic tx pool tests to use a real txhashset via chain adapter
* rework dandelion monitor to reflect recent discussion
works locally but needs a cleanup
* refactor dandelion_monitor - split out phases
* more pool test coverage
* remove old test code from pool (still wip)
* block_building and block_reconciliation tests
* tracked down chain test failure...
* fix test_coinbase_maturity
* dandelion_monitor now runs...
* refactor dandelion config, shared across p2p and pool components
* fix pool tests with new config
* fix p2p tests
* rework tx pool to deal with duplicate commitments (testnet2 limitation)
* cleanup and address some PR feedback
* add big comment about pre_tx...
* Clean server shutdown, generalizes usage of `Weak`. Introduces 2 main changes:
* A shared `AtomicBool` that signals server shutdown. All server
threads regularly check it to break out of their main loops when
it changes to `true`.
* Breaking of circular `Arc` references, which can never be
destroyed, by downgrading to `Weak` instead. Only the main server
keeps the `Arc` while all other components get the `Weak` variant.
Both of these are required for all long-living structs to be
cleanly destroyed. Note that in Rust this is fairly important as
most resource-freeing logic is associated with `drop`,
which is only called when said struct is free of scope or `Arc`
references.
Should address most of #536 (only need the stop hook to call
`Server` shutdown).
* Test for fast sync, followed by restart, followed by re-fast-sync
* P2P test fix
* Double sync taking too long for Travis, commenting out for now
* Re-introduce peer regular ping/pong
* Fix partial header reads. Turns out that on async tcp streams, even a small chunk like a
header can be read partially. So header read needs to rely on our
fixed-up `read_exact`, with an additional boolean to allow yield
when no bytes were read.
* First tests for API handlers
* Test chain UTXO handler
* Add test sumtrees handlers
* Fix typo
* Removed unused logger
* Update bitflags to ^1.0
* Missing test for bitflags update
* Moved test to grin directory
* Remove tests dependencies
* Add API P2P tests
* Fix hex string commitment
* Fix conflicting port
* Fix directory conflict and server port
* Wait for at least one block is mined on Travis
* first pass at allow/deny lists for hard-coded peers (not just seeds)
* commit
* add peers_allow and peers_deny examples and comments to grin.toml
* fix build issue with simulnet tests
* fix p2p tests
Moved handling to the peer map out of the p2p server and into
its own struct. Allowed factoring code from the net adapter and
simplification of some interactions. Also removes the need for
the adapter to reference the p2p server or peers.
Fixes#430, #453 and #456
