This commit includes the following updates:
- Added a new 'pprof' flag to the command-line arguments in main.go. This flag allows the user to specify a file name for writing CPU profile information, enabling performance analysis.
- Implemented functionality to start CPU profiling in the 'Before' function. If a file name is provided via the 'pprof' flag, the function creates the specified file and begins CPU profiling.
- Added an 'After' function to stop CPU profiling once the program execution is finished.
These changes provide a way to analyze the CPU usage of the 'lotus-shed' application, which can be valuable for performance tuning and optimization.
This commit includes the following updates:
- Imported v12 of the filecoin state types in migrations.go. This allows the system to interpret and operate on the latest structure of filecoin state information, ensuring compatibility with the latest version of the Filecoin network.
- Updated the 'getMigrationFuncsForNetwork' function to include a case for network.Version21, enabling the use of the UpgradeActorsV12 and PreUpgradeActorsV12 functions for network migration. These changes ensure the system correctly handles migrations when the network upgrades to version 21.
- Implemented a new 'checkNv21Invariants' function to check the invariants for version 21 of the Filecoin network. This function:
1. Loads the new state root from the actor store.
2. Retrieves the actor code IDs for the current state version (v12).
3. Loads the actor tree from the state root and checks state invariants using the actor code IDs.
4. Logs any error messages generated during the invariant check.
5. Finally, prints a message with the time taken to complete the checks.
By checking these invariants, we can ensure the system's state is consistent and valid after migrating to network version 21.
This commit refactors the code in `invariants.go` to support state invariant checks for different actor versions. The code now includes checks for versions 10 and 11 of the actors. The `CheckStateInvariants` function is invoked based on the actor version, passing the appropriate parameters. This change ensures that state invariant checks are performed correctly for different actor versions.
The changes made are as follows:
- Added imports for actor versions 10 and 11.
- Added `case` statements for versions 10 and 11 in the switch statement.
- Invoked `CheckStateInvariants` function with the correct parameters for each version.
- Handled errors returned by the `CheckStateInvariants` function.
These changes enhance the flexibility and compatibility of the code with different actor versions, improving the accuracy of state invariant checks.
This migrates everything except the `go-car` librairy: https://github.com/ipfs/boxo/issues/218#issuecomment-1529922103
I didn't migrated everything in the previous release because all the boxo code wasn't compatible with the go-ipld-prime one due to a an in flight (/ aftermath) revert of github.com/ipfs/go-block-format. go-block-format has been unmigrated since slight bellow absolutely everything depends on it that would have required everything to be moved on boxo or everything to optin into using boxo which were all deal breakers for different groups.
This worked fine because lotus's codebase could live hapely on the first multirepo setup however boost is now trying to use boxo's code with lotus's (still on multirepo) setup: https://filecoinproject.slack.com/archives/C03AQ3QAUG1/p1685022344779649
The alternative would be for boost to write shim types which just forward calls and return with the different interface definitions.
Btw why is that an issue in the first place is because unlike what go's duck typing model suggest interfaces are not transparent https://github.com/golang/go/issues/58112, interfaces are strongly typed but they have implicit narrowing. The issue is if you return an interface from an interface Go does not have a function definition to insert the implicit conversion thus instead the type checker complains you are not returning the right type.
Stubbing types were reverted https://github.com/ipfs/boxo/issues/218#issuecomment-1478650351
Last time I only migrated `go-bitswap` to `boxo/bitswap` because of the security issues and because we never had the interface return an interface problem (we had concrete wrappers where the implicit conversion took place).
This benchmark is designed to stress test the rpc methods of a lotus node so that we can simulate real world usage and measure the performance of rpc methods on the node.
This benchmark has the following features:
* Can query each method both sequentially and concurrently
* Supports rate limiting
* Can query multiple different endpoints at once (supporting different concurrency level and rate limiting for each method)
* Gives a nice reporting summary of the stress testing of each method (including latency distribution, histogram and more)
* Easy to use
To use this benchmark you must specify the rpc methods you want to test using the --method options, the format of it is:
--method=NAME[:CONCURRENCY][:QPS][:PARAMS] where only METHOD is required.
Here are some real examples:
lotus-bench rpc --method='eth_chainId' // run eth_chainId with default concurrency and qps
lotus-bench rpc --method='eth_chainId:3' // override concurrency to 3
lotus-bench rpc --method='eth_chainId::100' // override to 100 qps while using default concurrency
lotus-bench rpc --method='eth_chainId:3:100' // run using 3 workers but limit to 100 qps
lotus-bench rpc --method='eth_getTransactionCount:::["0xd4c70007F3F502f212c7e6794b94C06F36173B36", "latest"]' // run using optional params while using default concurrency and qps
lotus-bench rpc --method='eth_chainId' --method='eth_getTransactionCount:10:0:["0xd4c70007F3F502f212c7e6794b94C06F36173B36", "latest"]' // run multiple methods at once`,
