* 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
* 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
* 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
* Handle SIGINT and SIGTERM (#1180)
* Handle SIGINT and SIGTERM
* pin croaring to version 0.3.2 until we get the clang conflict sorted out (#1183)
* document proposals for - (#1190)
* conditional timelocked outputs, and
* conditional relative timelocked outputs
* problem with validation on rewind
* update difficulty scenarios to display much more data
* correct average sum output
* update pre-genesis block padding to just use previous block's data
* 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
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?
* move checker and rename to updater
* rustfmt
* complete checker/updater move
* rustfmt
* move libwallet error into separate file
* rustfmt
* starting to sort our error types
* updating errors in libtx and libwallet
* rustfmt
* factor out error type
* rustfmt
* compiling, errors split into libwallet and wallet errors
* rustfmt
* changing user error reporting to new format
* rustfmt
* clean up error types
* clean up error types
* move restore into libwallet
* rustfmt
* avoid repeated truncation in difficulty adjust + minor refactoring
* reinstate needed low-diffculty exception on dampening
* leave consensus breaking change for later one line change; obsolete lower testnet1 max target
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.
* large updates for mining, fix async mode, will list changes in PR
* reset config and build defaults
* change to difficulty calculations
* tweaking mining params and tests
* tweaking to tests
* including pre-genesis data for difficulty adjustments, adding adjustment scenario tests
* further clarifying next_difficulty function
* moving tests out of consensus.rs
* pow test fix
* changing pre-genesis generation
* 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
* fix test imports
* Limit number of inputs in a block, fix#261
* MAX_BLOCK_INPUTS = 300_000 // IO-time bound DoS protection. 5MB/s disk random reads gives ~150k UTXO lookups/s, so set limit at 300k UTXO inputs
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.
