* budget and system contracts and verification
* contract check_id methods
* system call contract
* verify contract execution rules
* move system into its own file
* allocate before transfer for budget
* store error in budget context
* budget contract and tests without bank
* moved budget of of bank
* Migrate Budget DSL to use the Account state instead of global bank data structures.
* Serialize Instruction into Transaction::userdata.
* Store the pending set in the Account::userdata
* Enforce the token balance rules on contract execution. This becomes the entry point for generic contracts.
* This pr will have a performance impact on the bank. The next set of changes will fix this by locking each account during multi threaded execution of all the contracts.
* With this change a contract transaction needs to store its state under an address. That address could be the destination of the tokens, or any random address. For the latter, an extra step would be needed to claim the tokens which isn't implemented by budget_dsl at the moment.
* test tracking issue 1157
We'll avoid introducing three-letter terms to free up the namespace
for three-letter acronyms.
But recognize the term "sigverify", a verb, to verify a digital
signature.
clear flags on fresh blobs, lest they sometimes impersonate coding blobs...
fix bug: advance *received whether the blob_index is in the window or not,
failure to do so results in a stalled repair request pipeline
* limit the number of Tntries per Blob to at most one
* limit the number of Transactions per Entry such that an Entry will
always fit in a Blob
With a one-to-one map of Entries to Blobs, recovery of a validator
is a simple fast-forward from the end of the initial genesis.log
and tx-*.logs Entries.
TODO: initialize validators' blob index with initial # of Entries.
It's now a Tick that locks down event order. Before this change, the
event order would be locked down in the order the server sees it.
