Simplify usage of `FixedHash` field on `Block` type

m-Peter commented 3 weeks ago

Description

It is safer/simpler to use the gethCommon.Hash type for FixedHash, instead of a *string, all we have to do is check that FixedHash is not the empty hash. The problem is that this change will require a re-index, so I am not sure if it is worth it. DO NOT MERGE UNLESS REINDEX

Walkthrough

The changes involve updates to the Block structure in models/block.go, specifically altering the FixedHash field from a pointer to a string to a value of type gethCommon.Hash. This simplifies hash handling and improves method logic. Corresponding test files were updated to ensure proper validation of block hashes, and an adjustment was made to the expected block size in a JavaScript test file.

Changes

Files	Change Summary
`models/block.go`, `models/block_test.go`	Modified `Block` structure to change `FixedHash` from `*string` to `gethCommon.Hash`; updated related methods and tests for hash validation.
`tests/web3js/eth_non_interactive_test.js`	Updated expected value for `block.size` from `3995n` to `4028n` in a test case.

🐰 In the meadow where bunnies play,
A change was made, hip-hip-hooray!
No more pointers, just a hash,
Simplified logic in a flash!
With tests updated, all is bright,
Hopping forward, what a delight! 🌼✨

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 .` - `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 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 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. 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. ### Other keywords and placeholders - Add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. - Add `@coderabbitai summary` to generate the high-level summary at a specific location in the PR description. - Add `@coderabbitai` anywhere in the PR title to generate the title automatically. ### CodeRabbit Configuration 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.

Yeah this is nicer, I did have this approach but with a pointer, I should remove the pointer. I think this is good but I wouldn't do it unless we plan a reindex anyway. So we can keep this in draft until then and add a comment in the description DO NOT MERGE UNLESS REINDEX
