Yeastplume 42376e68bc Cuckoo-miner better merged into Grin (#80)
* Adding cuckoo-miner into grin as a proper dependency now
* Defaulting to using cuckoo-miner
* Updates to tests to use cuckoo_miner by default, (using cuckoo16)
2017-07-18 20:57:09 +00:00
Yeastplume 1ede61d2a2 Addition of configuration file (#79)
* addition of configuration file to grin executable, instructions on how it's picked up are in grin.toml
* Starting to add a configuration file, and change some elements of configuration structures to make them more consistent

Yeastplume 12480e7310 Changes to allow for testing and playing with cuckoo-miner integration (#76)
* Refactoring to allow for different miner implementations. Added conditional support for compiling and loading the cuckoo-miner plugin project.
* Small changes to experimentally integrate with cuckoo-miner and compatibility with latest version of cuckoo-miner.
* Turning off inclusion of cuckoo_miner by default
* Disabling simulate_parallel_mining test for now

Ignotus Peverell 15ea8da34a New Chain struct acting as facade for all chain operations
Introduce a new Chain struct that maintains the current head,
acts as facade to the store and the block processing pipeline
and handles all appropriate locking.

All higher level components, like the overall server, REST APIs
and miner have been update to only depend on Chain. Cleaned up
some duplication and tests now that there's a single entry point
to all blockchain operations.

Yeastplume 97b7421ce0 Mining test debug output, fixes to diff. adjustment and start of POW documentation (#69)
* Beginning to add a POW description, and some minor changes to mining testing, addition of further debug information to mining output.
* Many additions to create first draft of POW documentation
* Fixes to difficult adjustments by adding a MINIMUM_DIFFICULTY consensus value. Otherwise never adjusted above 1 due to flooring.

Yeastplume 5f8a0d9f1c Wallet HTTP posting, fixes and additions to port address configurability. (#66)
* Starting to refactor test, adding http post to wallet sender
* Implemented ability to run servers on different ports (mostly for testing), and implemented ability to post http requests directly to receiving wallets
* Adding detailed instructions on running multiple servers on the same machine
* Changes to build.doc to outline server running process
* Removed unwanted debug statements
* WIP Local server testing framework evolution
* More refactoring of server pool, checked in because there's a problem
* Added server reference structure, and ability to return server references from tests cleanly
* Added simulate_parallel_mining test, which puts some artificial slowdown into test mining loops, and the difficulty can currently be watched in the log
* Removing the ServerRef structure placed in earlier and replaced with a ServerStats structure, that just returns relevant info about the Server state without exposing it to the world

Ignotus Peverell e8a6b61100 Apply new difficulty algo, remove configurable cuckoo size
Integrate the new difficulty calculation into the block chain
validation, the miner and tests. As the difficulty calculation
doesn't use varying Cuckoo sizes anymore and we narrowed down
reasonable final Cuckoo Cycle parameters, removed all Cuckoo
Cycle sizes from block headers.

Formalized easier Cuckoo Cycle sizes for testing (and possibly
testnet) by introducing a test mode in configuration. Updated
all tests.

Ignotus Peverell 6523966f9e Bug fixes in wallet and related API
Fixes a few loose ends in the full cycle of sending coins,
accepting them, pushing that transaction to the pool and having it
mined. More specifically:

* The API output endpoint needs to be a UTXO endpoint, as the
server can't make any guarantee about having a spent output.
* Bubbling up HTTP not found errors.
* Wallet output status checker now handles spent outputs.
* Transaction pool validates the transaction before accepting it.
* Fixed the operation API routes.
* Fixed too greedy wallet coin selection loop.

Ignotus Peverell eb9cc7ef13 Integrate transaction pool with rest of the system
* Transactions coming from the network are now pushed to the pool
through the net adapter.
* New blocks accepted by the chain are sent to the pool for
eviction.
* The miner requests transactions from the pool to build its
blocks.
* The push API adds to the pool, removing the mock.
* Implementation of the adapter to the chain required by the pool
to get consistent UTXOs. Grossly unoptimized until we have the UTXO
MMR ready.

Ignotus Peverell 791d2355ee Miner querying wallet receiver for coinbase output
With the coinbase receiver daemon in place, when starting a Grin
server in mining mode, the miner will now ask the receiver for a
coinbase output. The output is then used to insert in a block when
successfully mined.

Ignotus Peverell 1b78a73328 Variety of small p2p fixes to block sync
Adds a couple utility function to p2p server to check whether
we're already connected to a peer before trying again. Other
very minor fixes and logging improvements.

Ignotus Peverell 3fe28b0f03 Server types cleanup and serde for configuration types
Moved error and configuration types from server.rs to types.rs
where they should have been from the start. Configuration types
for the server and p2p modules now derive serde Serialize and
Deserialize so we can have a simple JSON configuration file.

Ignotus Peverell eb024e91d2 Discovery and seeding of other peers. Relies either on a gist with IP addresses or a static list. Connects to a first list, sending peer request messages to discover more. Monitor the server to make sure there's always enough peer connections. 2017-02-18 18:42:34 -08:00

Ignotus Peverell 0cc786a1e5 Refactored server to share the same struct whether futures are exposed or not. Multi-server test now properly waits for a block instead of a timer. 2016-12-23 12:15:36 -08:00
Ignotus Peverell f067e18644 Adapters between the chain and the network for block broadcast. First working test that spins up 5 servers, connects them all together, mine a block on one and watch it getting added to all the other servers chains. Some improvements still needed to automate the test properly. 2016-12-20 17:39:02 -08:00
Ignotus Peverell e688ff99e6 Started putting in place the adapter between the chain and p2p modules to forward blocks and transactions. Cleaned up chain store references. 2016-12-18 15:51:54 -08:00
Ignotus Peverell d395b3d128 Added another server implementation for when the client needs to stay in control of the event loop (i.e. multiple servers for tests). Test to spin up 5 servers and connect them all together. 2016-12-14 16:10:39 -08:00
