Usage of 'fixed-size' integer types in RTI code #453

Open Jakio815 opened 3 months ago

Jakio815 commented 3 months ago

This resolves issue #449.

  1. Clarified types of federate_id, which was defined as just int not int32_t, which could make problems on 16-bit systems.

  2. Also, change the runtime clock-synchronization after initial clock-sync, to send a 2 byte uint16_t federate_id not int32_t which is 4 bytes.

Walkthrough

The changes standardize the data type used for a federate ID across multiple files, switching from int and int32_t to uint16_t. This improves consistency and prevents potential issues, particularly on 16-bit systems. Moreover, checks for the number of federates, which might exceed uint16_t limits, are removed to prevent unnecessary constraints.

Changes

File Path Change Summary
core/federated/RTI/rti_remote.c Updated message size calculation and type casting in clock synchronization thread function
core/federated/clock-sync.c Modified federate ID encoding from int to uint16_t for clock sync messages
core/federated/federate.c Removed checks for excess number of federates in connection functions
core/utils/util.c Changed _lf_my_fed_id type from int to uint16_t and updated associated logic
include/core/utils/util.h Updated _lf_my_fed_id and related functions to use uint16_t instead of int

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 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 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.

@edwardalee?

Jakio815 commented 2 months ago

I'm still getting failures on this test, ./gradlew core:compileKotlin on Windows. Does anyone have ideas about this?

cmnrd commented 2 months ago

No, the error is really odd. It seems to be related to some caching mechanism. @lhstrh do you have any idea why this fails? Is there a way to reset the CI cache?

Nope. Not a Windows user... Remove the Gradle cache and try again? It looks like this PR was almost ready to merge but somehow got stuck. How do we move it forward?
