Solution:

support generating a single node and use shell to parallelize it

for example:

$ seq 0 9 | xargs -P10 -I{} nix run .#stateless-testcase -- gen-txs /tmp/data/out --node {}

Run nix run .#stateless-testcase -- --help to make sure it's built first, because the build part can't run in parallel.

Walkthrough

The changes involve modifications to the gen_genesis function in peer.py, specifically adjusting the handling of the accounts list to exclude the first account, which is the validator account of the first node. Additionally, an optional command-line argument --node is introduced in the gen_txs function in stateless.py, allowing users to generate transactions for a specific node. The function signatures are updated accordingly, and the path for preparing the genesis file is changed.

Changes

File Path	Change Summary
testground/benchmark/benchmark/peer.py	Modified `gen_genesis` function to skip the first account in the `accounts` list, ensuring only subsequent nodes are included.
testground/benchmark/benchmark/stateless.py	Updated `gen_txs` and `_gen_txs` function signatures to include an optional `node` parameter. Logic modified to generate transactions conditionally based on the presence of `node`. Path for genesis file preparation changed from `FULLNODE_GROUP` to `VALIDATOR_GROUP`.

🐇 In the meadow, transactions flow,
With a node to guide, watch them grow.
A sprinkle of code, a dash of delight,
Generating paths, both day and night.
Hops of joy in every line,
A new feature's here, oh how divine! 🌼

testground/benchmark/benchmark/peer.py (1)
`89-93`: **LGTM!** The code change correctly skips the first account in the `accounts` list, which corresponds to the validator account of the first node. This prevents duplicating the validator account in the genesis file, as it is already added using the home directory of that node. The updated logic ensures that the `accounts` list only contains the accounts from the subsequent nodes, which is the desired behavior.

Tips

### Chat There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai): - Review comments: Directly reply to a review comment made by CodeRabbit. Example: -- `I pushed a fix in commit , please review it.` -- `Generate unit testing code for this file.` - `Open a follow-up GitHub issue for this discussion.` - 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 gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.` -- `@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 using 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.
