* Update cost model to use requested_cu instead of estimated cu #27608
* remove CostUpdate and CostModel from replay/tvu
* revive cost update service to send cost tracker stats
* CostModel is now static
* remove unused package
Co-authored-by: Tao Zhu <tao@solana.com>
Tenets:
1. Limit thread names to 15 characters
2. Prefix all Solana-controlled threads with "sol"
3. Use Camel case. It's more character dense than Snake or Kebab case
* Pass the sum of consumed compute units to cost_tracker
* cost model tracks builtins and bpf programs separately, enabling adjust block cost by actual bpf programs execution costs
* Copied nightly-only experimental `checked_add_(un)signed` implementation to sdk
* Add function to update cost tracker with execution cost adjustment
* Review suggestion - using enum instead of struct for CommitTransactionDetails

* review - rename variable to distinguish accumulated_consumed_units from individual compute_units_consumed
* not to use signed integer operations
* Review - using saturating_add_assign!(), and checked_*().unwrap_or()
* Review - using Ordering enum to cmp
* replace checked_ with saturating_
* review - remove unnecessary Option<>
* Review - add function to report number of non-zero units account to metrics
1. use was_executed to correctly identify transactions requires cost adjustment;
2. add function to specifically handle executino cost adjustment without have to copy accounts
- don't store pending tx signatures and costs in CostTracker
- apply tx costs to global state immediately again
- go from commit_or_cancel to update_or_remove, where the cost tracker
is either updated with the true costs for successful tx, or the costs
of a retryable tx is removed
- move the function into qos_service and hold the cost tracker lock for
the whole loop
* - report cost details for transactions selected to be packed into block;
- report estimated execution units packed into block, and actual units and time after execution
* revert reporting per-transaction details
* rollup transaction cost details (eg signature cost, wirte lock, data cost and execution costs) into block stats
* change naming from units to cu, use struct to replace tuple
* - qos_service metrics tagged with leader thread ids to separate gossip/tpu votes and transactions;
- qos_service metrics is reported with bank slot;
- replaced timer-based reporting with signal via channel; removed async report test as qos_service now lives within a thread
* - add tpu live packets (eg, not buffered packets) states to qos metrics reporting
* use cost model to limit new account creation
* handle every system instruction
* remove &
* simplify match
* simplify match
* add datapoint for account data size
* add postgres error handling
* handle accounts:unlock_accounts
with results code path.
- fix a bug that could unlock accounts that weren't locked
- add test to the refactored function
- skip enumerating transaction accounts if qos results is an error
- add #[must_use] annotation
- avoid clone error in results
- add qos error code to unlock_accounts match statement
- remove unnecessary AbiExample
* - cache calculated transaction cost to allow sharing;
- atomic cost tracking op;
- only lock accounts for transactions eligible for current block;
- moved qos service and stats reporting to its own model;
- add cost_weight default to neutral (as 1), vote has zero weight;
