experiment: dynamic-timeouts-base

[coderabbitai[bot]]

Walkthrough

## Walkthrough The recent code updates introduce dynamic timeout tests, enable enhanced network experimentation features, and modify node configurations for improved networking. Key changes include adding new test cases and network experiments, enabling bit-twisting functionality, and altering default configuration values for network addresses. ## Changes | File Path | Change Summary | | ------------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `app/test/dynamic_timeouts_test.go` | Added a test case for dynamic timeouts, setting up configurations and interacting with a test network. | | `go.mod` | Updated dependency version for `github.com/tendermint/tendermint`. | | `test/e2e/experiment/dynamic_timeouts.go` | Implemented a network experiment with 20 nodes running dynamic timeout tests, adjusting latencies, and saving performance data. | | `test/e2e/experiment/.../dynamic_timeouts.go` | Created a new program to set up and test a network with dynamic timeouts, logging height information until the test completes. | | `test/e2e/testnet/node.go` | Enabled bit twister functionality before starting nodes, with error handling. | | `test/util/testnode/config.go` | Modified `DefaultTendermintConfig` to use `0.0.0.0` instead of `127.0.0.1` for `GRPCListenAddress`. | | `test/util/testnode/full_node.go` | Changed `newLogger` to allow info messages instead of only errors. | | `test/util/testnode/network.go` | Updated `NewNetwork` function to accept an optional `validatorIndex` parameter for initializing files based on a provided index. | | `test/util/testnode/rpc_client.go` | Updated `DefaultAppConfig` to use `0.0.0.0` instead of `127.0.0.1` for GRPC address format. |

Additional comments not posted (6)

test/util/testnode/full_node.go (1)

`56-56`: **Adjust Logging Level to Info** The logging level has been adjusted to allow info messages. This change will increase the verbosity of logs, which can be beneficial for debugging but may affect performance due to increased I/O operations. Ensure this change is aligned with the intended use cases and consider making this behavior configurable to adapt to different environments.

test/util/testnode/network.go (1)

`19-25`: **Flexible Network Initialization with Optional `validatorIndex`** The introduction of an optional `validatorIndex` parameter in the `NewNetwork` function is a positive change, enhancing the flexibility of network initialization. This allows for specifying different configurations for different validators, which can be particularly useful in testing scenarios involving multiple nodes. Ensure that this change is well-documented and that downstream code that relies on the default behavior is updated accordingly.

test/e2e/experiment/dymamic_timeouts.go (4)

`17-20`: **Well-handled error in main function.** The error handling and logging in the `main` function are correctly implemented, ensuring that any failures in the `Run` function are logged before the program exits. --- `23-108`: **Comprehensive error handling in Run function.** The `Run` function is well-structured with comprehensive error handling for each operation involved in setting up and running the network test. This includes handling errors for network creation, node setup, and during the test run.

--- `111-164`: **Efficient management of resources and error handling in saveStartTimes.** The `saveStartTimes` function efficiently manages file resources with proper error handling and resource cleanup. The use of defer for file closing and CSV writer flushing is a good practice. --- `166-204`: **Proper resource management in saveBlockTimes function.** The `saveBlockTimes` function correctly manages file resources and handles errors efficiently. The structured error handling ensures that any issues during the data gathering and writing process are caught and handled appropriately.

Tips

### Chat There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai): > :bangbang: **IMPORTANT** > Auto-reply has been disabled for this repository in the CodeRabbit settings. The CodeRabbit bot will not respond to your replies unless it is explicitly tagged. - Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples: - `@coderabbitai generate unit testing code for this file.` - `@coderabbitai modularize this function.` - PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples: - `@coderabbitai generate interesting stats about this repository and render them as a table.` - `@coderabbitai show all the console.log statements in this repository.` - `@coderabbitai read src/utils.ts and generate unit testing code.` - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.` - `@coderabbitai help me debug CodeRabbit configuration file.` Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments. ### CodeRabbit Commands (invoked as PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai full review` to do a full review from scratch and review all the files again. - `@coderabbitai summary` to regenerate the summary of the PR. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository. - `@coderabbitai help` to get help. Additionally, you can add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. ### CodeRabbit Configration File (`.coderabbit.yaml`) - You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository. - Please see the [configuration documentation](https://docs.coderabbit.ai/guides/configure-coderabbit) for more information. - If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json` ### Documentation and Community - Visit our [Documentation](https://coderabbit.ai/docs) for detailed information on how to use CodeRabbit. - Join our [Discord Community](https://discord.com/invite/GsXnASn26c) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.
