Relax validation checks for transaction arguments/payload

[m-Peter]

Description

As a source of inspiration for these validation checks, we used the Geth repository.
However, some of these checks are merely warnings, and would be too restrictive. So we remove them.
Some community members already reported examples of misbehavior: https://discord.com/channels/613813861610684416/1162086721471647874/1262826868651065476 .

Summary by CodeRabbit

• Refactor

  • Simplified transaction validation by removing specific checks for payload size, checksum validity, and data structure.

• Tests

  • Updated transaction validation test cases to reflect the simplified validation logic. Removed tests for small payloads, invalid transaction data lengths, and checksum validations.

Walkthrough

The recent changes primarily involve the removal of various validation checks across multiple files. These checks pertained to transaction data validation, including payload size, checksum validity, and data structure compliance. This simplification affects both the main transaction validation logic and the associated test cases, which no longer initialize or test for these conditions.

Changes

Files	Change Summary
api/models.go	Removed fmt package import and several transaction validation checks, including payload size and checksum validity.
api/models_test.go	Simplified TestValidateTransaction by removing initialization and test cases for small payload and invalid transaction data.
models/transaction.go	Eliminated transaction data length checks and recipient address checksum validation in the ValidateTransaction function.
models/transaction_test.go	Removed initialization of certain transaction payloads and related test cases to simplify the test setup.

Poem

In the code, a change took flight,
Validation checks took their last rite.
No more payloads small or checksums tall,
Simplified paths for one and all.
The code, now sleek, does hum and sing,
A rabbit's joy in every spring.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • 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.
