- All enhancement, bugfix, or change requests must begin with the creation of a TensorRT Issue Request.
- The issue request must be reviewed by TensorRT engineers and approved prior to code review.
-
All source code contributions must strictly adhere to the TensorRT Coding Guidelines.
-
In addition, please follow the existing conventions in the relevant file, submodule, module, and project when you add new code or when you extend/fix existing functionality.
-
To maintain consistency in code formatting and style, you should also run
clang-format
on the modified sources with the provided configuration file. This applies TensorRT code formatting rules to:- class, function/method, and variable/field naming
- comment style
- indentation
- line length
-
Format git changes:
# Commit ID is optional - if unspecified, run format on staged changes. git-clang-format --style file [commit ID/reference]
-
Format individual source files:
# -style=file : Obtain the formatting rules from .clang-format # -i : In-place modification of the processed file clang-format -style=file -i -fallback-style=none <file(s) to process>
-
Format entire codebase (for project maintainers only):
find samples plugin -iname *.h -o -iname *.c -o -iname *.cpp -o -iname *.hpp \ | xargs clang-format -style=file -i -fallback-style=none
-
Avoid introducing unnecessary complexity into existing code so that maintainability and readability are preserved.
-
Try to keep pull requests (PRs) as concise as possible:
- Avoid committing commented-out code.
- Wherever possible, each PR should address a single concern. If there are several otherwise-unrelated things that should be fixed to reach a desired endpoint, our recommendation is to open several PRs and indicate the dependencies in the description. The more complex the changes are in a single PR, the more time it will take to review those changes.
-
Write commit titles using imperative mood and these rules, and reference the Issue number corresponding to the PR. Following is the recommended format for commit texts:
#<Issue Number> - <Commit Title>
<Commit Body>
-
Ensure that the build log is clean, meaning no warnings or errors should be present.
-
Ensure that all
sample_*
tests pass prior to submitting your code. -
All OSS components must contain accompanying documentation (READMEs) describing the functionality, dependencies, and known issues.
- See
README.md
for existing samples and plugins for reference.
- See
-
All OSS components must have an accompanying test.
- If introducing a new component, such as a plugin, provide a test sample to verify the functionality.
-
To add or disable functionality:
- Add a CMake option with a default value that matches the existing behavior.
- Where entire files can be included/excluded based on the value of this option, selectively include/exclude the relevant files from compilation by modifying
CMakeLists.txt
rather than using#if
guards around the entire body of each file. - Where the functionality involves minor changes to existing files, use
#if
guards.
-
Make sure that you can contribute your work to open source (no license and/or patent conflict is introduced by your code). You will need to
sign
your commit. -
Thanks in advance for your patience as we review your contributions; we do appreciate them!
Developer workflow for code contributions is as follows:
-
Developers must first fork the upstream TensorRT OSS repository.
-
Git clone the forked repository and push changes to the personal fork.
git clone https://github.com/YOUR_USERNAME/YOUR_FORK.git TensorRT
# Checkout the targeted branch and commit changes
# Push the commits to a branch on the fork (remote).
git push -u origin <local-branch>:<remote-branch>
- Once the code changes are staged on the fork and ready for review, a Pull Request (PR) can be requested to merge the changes from a branch of the fork into a selected branch of upstream.
- Exercise caution when selecting the source and target branches for the PR.
Note that versioned releases of TensorRT OSS are posted to
release/
branches of the upstream repo. - Creation of a PR creation kicks off the code review process.
- Atleast one TensorRT engineer will be assigned for the review.
- While under review, mark your PRs as work-in-progress by prefixing the PR title with [WIP].
- Since there is no CI/CD process in place yet, the PR will be accepted and the corresponding issue closed only after adequate testing has been completed, manually, by the developer and/or TensorRT engineer reviewing the code.
-
We require that all contributors "sign-off" on their commits. This certifies that the contribution is your original work, or you have rights to submit it under the same license, or a compatible license.
- Any contribution which contains commits that are not Signed-Off will not be accepted.
-
To sign off on a commit you simply use the
--signoff
(or-s
) option when committing your changes:$ git commit -s -m "Add cool feature."
This will append the following to your commit message:
Signed-off-by: Your Name <[email protected]>
-
