* 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
* get rid of RwLock around peer instances
* rustfmt
* rename stuff to live_info
* rustfmt
* serialize into PeerInfoDisplay
limit live_info write lock to peer_info.update()
rename to PeerLiveInfo
* simplify broadcast logic a bit more
connected peers are connected by definition
* return true/false on broadcast so we can send to more peers
* rustfmt
* fix p2p and server tests for PeerInfoDisplay
* commit
* 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
* Use internal hashmap for count and contains methods instead of relying on
connected_peers method which is expensive (creates vector from hashmap)
* Reduce number of `clone()`
* Refactor broadcast_xxx
* Transaction max weight expressed in terms of block weight
* Cleaned up max block sizes, so everything is in therms of weight
* Cleanup block max constants
* Rename verify_size -> verify_weight
* 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'
* Make grin.toml config optional. Mirror exisiting config parameters in grin.toml to source code, so binary can run without a config file. Add test for it.
* fixup! Make grin.toml config optional
