* Add api_secret
* Add to base64 method
* Add basic auth in API
* Add Basic Auth to owner API
* Add flag to enable disable basic auth
* Add .api_secret file
* 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
Currently on startup we wait for 30 secs if we don't have at least 4 peers with more work. If a node was quickly restarted it is already fully synced so thereare no peers with more work at all. This pr assumes that if we've done some work already and we have enough peers but still 0 with more work we are fully synced and good to go.
* fix for unstable travis-ci test on servers module
* skip the PeerWithSelf connection request on sending side
* logs and comments change; and remove an unnecessary unwrap() in test
* improve: HeaderSync optimization (#1372)
* remove get_locator() optimization, which should be an independent pr for security review
* refactoring: move 'headers_streaming_body()' from Message to Protocol
* move 2 headers utils functions out of Protocol, and remove 'pub'
* support reading variable size of BlockHeader, from Cuckoo30 to Cuckoo36
* fix: use global::min_sizeshift() instead of hardcoded 30, because Cuckoo10 will be used for AutomatedTesting chain
* fix: should use global::proofsize() instead of hardcoded 42 when calculate serialized_size_of_header
* replace another 42 with global::proofsize()
* config file can now be generated by executable
* rustfmt
* remove now-unnecessary config defaults test
* set up paths and config file creation in user's home directory
* rustfmt
* remove default grin.toml
* add grin configuration command to spit out config file
* Split configuration into wallet and server
* rustfmt
* Restore logging to wallet configurations
* rustfmt
* simplify tx validation and aggregation
we *only* need to account for reward when building a block from txs
* rustfmt
* cleanup and tests passing
* rustfmt
* better comments in with_reward()
* fix wallet tests
* refactoring get_locator(), to ensure the gap between neighbours >= 2^n
* security enhancement for get_locator
* in case of sync head and the header head are different, clear history locators
Header sync used to run when complete (right count of blocks
received) or every 10 sec regardless. Sometimes 10 secs is not
enough, especially when a big batch of blocks bodies is arriving
at the same time.
This tweaks the time-based heuristic just a bit to only ask for
headers when stalled, meaning that the header head has not
*progressed* for 10 seconds.
* Fix bad header sync timeout logic
* Improve stability of fast sync test
Adds regular pings so that the 2 test servers know each others'
heights (necessary to find most work peer). Stop mining on the
first server once the 2nd kicks in. Avoids chasing a fast moving
target on Cuckoo10.
* Include commitments non-duplicate checks in aggregate
* Remove said check from the pool
* Block building now uses tx aggregation to reduce duplication
* fix: in case txhashset validation fail, 'TxHashsetDownload' should retry (#1293)
And add 2 more fixes:
1. handle sending request failure of 'send_txhashset_request';
2. use a 10-mins timeout to handle noresponse failure, in case a peer ignore our txhashset request, or in case a peer fail to send a file for some reason.
* Remove Iron dependecy and update hyper to version 0.12 #876
* REMOVE ME
* Revert "REMOVE ME"
This reverts commit e9a976eee98a2d5a4dfae5d9e1e4f5ed640c05d3.
* Rebase and start updating libwallet
Libwallet doesn't compile yet.
* Wallet compiles
* Grin compiles
* No compilation errors in tests
* All tests pass
* Reeturn future from handler
* Refactoring
* Fix lifetime issue one more time
I have to force push to rollback all the work done in last 2 days
* Fix wallet send issue
* Clean up
* 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'
* Remove now unnecessary txhashset write lock
* Ring buffer of hashes the chain has already processed
* Specifically report too old blocks as peer should be banned
* Move sync check for block relay, clean TODO
* No use processing transactions when syncing
* Ignore blocks older than horizon in pruning nodes
* fix misbehaving simulnet fastsync test
cleanup redundant cutoff vs bitmap params is rewind and check_compact
* make sure we do not verify full kernel history on a writeable txhashset extension
rework simulnet simulate_fast_sync test to be more robust
* fixup store tests
* sleep for a bit longer to give nodes time to update
their sync_state correctly
* tweak timing of simulate_block_propagation
* A new sync status enum encapsulated in a state struct allows tracking of where sync is at. Leveraging it in the TUI to provide more helpful messages.
* Percentage progression for most sync steps
* 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
* 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
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?
