2fa32d15ce Rustify core/src/core (#1122)
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?

1bad7188b7 Fix Readable impl for Transaction (#795)
Fuzz test demonstrated that the current implemenation panics on reading from the network when serialized tx. Contains for example huge number of input or outputs. It allows a mailicious sender
to kill the server.

fix - sort tx inputs/outputs (#533) (#542)
* added debug logging to see what we're doing in save_pos_index

* add counts to logging

* make sure inputs/outputs in tx are sorted
tweak debug logging

* DRY up sorting of inputs/outputs/kernels via a simple sort() in ser/deser

* add explicit validation fo sort order during tx and block validation

* sort order consensus rule for inputs/outputs/kernels in blocks

* we want a max of 10*num_peers blocks during sync...
not min

Cleanup HTTP APIs, update ports to avoid gap, rustfmt
Moved the HTTP APIs away from the REST endpoint abstraction and
to simpler Hyper handlers. Re-established all routes as v1.
Changed wallet receiver port to 13415 to avoid a gap in port
numbers.

Finally, rustfmt seems to have ignored specific files arguments,
running on everything.

Half of fees get rewarded, half burnt. Minor cleanups
Update coinbase building and block summation to account for half of
the fees going to the coinbase. Forcing fees to be even as a
consequence. Now that we can't build the coinbase independently
from the block (because fees), had to update the miner to keep the
key derivation so a new derivation isn't made any time a new block
gets worked on.

Minor doc and warning cleanups.

95a92eefc9 Cannot spend coinbase for N blocks (#111)
* use head_header in add_to_memory_pool
* add COINBASE_MATURITY const to consensus
* add coinbase maturity (wip) validaton rule to validate_block
* add coinbase maturity check to validate_block
* map errors in adapters - specific errors still wip
* reworked so adapter translates chain errors to pool errors (core errors not required)
* add test for spending immature coinbase in memory pool
* wip - add test to cover spending coinbase output in chain.process_block
* added test coverage around process_block - we have a problem with coinbase output commitments
* add a comment on the failing test
* process_block will now fail validation if we attempt to spend coinbase that has not yet matured
(remember to use a new reward_key for every block). test coverage in place to verify this

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.

Block now uses the new Target type. Consensus next_target calculation adjusting every block based on deviation and increasing Cuckoo size gradually. Block time of a minute until we learn more from mining ecosystem, so enough PoW attempts can be made even on CPUs. 2016-11-15 14:41:16 -08:00
