Rather, use issues or discussion topics to discuss whatever needs discussing. * We reserve full and final discretion over whether or not we will merge a pull request. Adhering to these guidelines is not a complete guarantee that your pull request will be merged. -## CI for pull requests +### CI for pull requests * Pull requests will need to pass all continuous integration checks before merging. * For faster iteration and more control, consider running CI on your own fork or when possible directly locally. * Submitting changes to an open pull request will move it to 'draft' state. * Pull requests will get a complete run on the main repo CI only when marked as 'ready for review' (via Web UI, button on bottom right). -## Nightly CI - -* Packages creation and long running tests will be performed during a nightly run -* On your fork you can trigger long running tests (NightlyTests.yml) for any branch following information from https://docs.github.com/en/actions/using-workflows/manually-running-a-workflow#running-a-workflow - -## Building - -* To build the project, run `make`. -* To build the project for debugging, run `make debug`. -* For parallel builds, you can use the [Ninja](https://ninja-build.org/) build system: `GEN=ninja make`. - * The default number of parallel processes can lock up the system depending on the CPU-to-memory ratio. If this happens, restrict the maximum number of build processes: `CMAKE_BUILD_PARALLEL_LEVEL=4 GEN=ninja make`. - * Without using Ninja, build times can still be reduced by setting `CMAKE_BUILD_PARALLEL_LEVEL=$(nproc)`. - -## Testing - -* Unit tests can be written either using the sqllogictest framework (`.test` files) or in C++ directly. We **strongly** prefer tests to be written using the sqllogictest framework. Only write tests in C++ if you absolutely need to (e.g. when testing concurrent connections or other exotic behavior). -* Documentation for the testing framework can be found [here](https://duckdb.org/dev/testing). -* Write many tests. -* Test with different types, especially numerics, strings and complex nested types. -* Try to test unexpected/incorrect usage as well, instead of only the happy path. -* `make unit` runs the **fast** unit tests (~one minute), `make allunit` runs **all** unit tests (~one hour). -* Make sure **all** unit tests pass before sending a PR. -* Slower tests should be added to the **all** unit tests. You can do this by naming the test file `.test_slow` in the sqllogictests, or by adding `[.]` after the test group in the C++ tests. -* Look at the code coverage report of your branch and attempt to cover all code paths in the fast unit tests. Attempt to trigger exceptions as well. It is acceptable to have some exceptions not triggered (e.g. out of memory exceptions or type switch exceptions), but large branches of code should always be either covered or removed. -* DuckDB uses GitHub Actions as its continuous integration (CI) tool. You also have the option to run GitHub Actions on your forked repository. For detailed instructions, you can refer to the [GitHub documentation](https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/enabling-features-for-your-repository/managing-github-actions-settings-for-a-repository). Before running GitHub Actions, please ensure that you have all the Git tags from the duckdb/duckdb repository. To accomplish this, execute the following commands `git fetch --tags` and then -`git push --tags` These commands will fetch all the git tags from the duckdb/duckdb repository and push them to your forked repository. This ensures that you have all the necessary tags available for your GitHub Actions workflow. - -## Formatting - -* Use tabs for indentation, spaces for alignment. -* Lines should not exceed 120 columns. -* To make sure the formatting is consistent, please use version 11.0.1, installable through `python3 -m pip install clang-format==11.0.1` or `pipx install clang-format==11.0.1`. -* `clang_format` and `black` enforce these rules automatically, use `make format-fix` to run the formatter. -* The project also comes with an [`.editorconfig` file](https://editorconfig.org/) that corresponds to these rules. - -## C++ Guidelines - -* Do not use `malloc`, prefer the use of smart pointers. Keywords `new` and `delete` are a code smell. -* Strongly prefer the use of `unique_ptr` over `shared_ptr`, only use `shared_ptr` if you **absolutely** have to. -* Use `const` whenever possible. -* Do **not** import namespaces (e.g. `using std`). -* All functions in source files in the core (`src` directory) should be part of the `duckdb` namespace. -* When overriding a virtual method, avoid repeating virtual and always use `override` or `final`. -* Use `[u]int(8|16|32|64)_t` instead of `int`, `long`, `uint` etc. Use `idx_t` instead of `size_t` for offsets/indices/counts of any kind. -* Prefer using references over pointers as arguments. -* Use `const` references for arguments of non-trivial objects (e.g. `std::vector`, ...). -* Use C++11 for loops when possible: `for (const auto& item : items) {...}` -* Use braces for indenting `if` statements and loops. Avoid single-line if statements and loops, especially nested ones. -* **Class Layout:** Start out with a `public` block containing the constructor and public variables, followed by a `public` block containing public methods of the class. After that follow any private functions and private variables. For example: - ```cpp - class MyClass { - public: - MyClass(); - - int my_public_variable; - - public: - void MyFunction(); - - private: - void MyPrivateFunction(); - - private: - int my_private_variable; - }; - ``` -* Avoid [unnamed magic numbers](https://en.wikipedia.org/wiki/Magic_number_(programming)). Instead, use named variables that are stored in a `constexpr`. -* [Return early](https://medium.com/swlh/return-early-pattern-3d18a41bba8). Avoid deep nested branches. -* Do not include commented out code blocks in pull requests. - -## Error Handling - -* Use exceptions **only** when an error is encountered that terminates a query (e.g. parser error, table not found). Exceptions should only be used for **exceptional** situations. For regular errors that do not break the execution flow (e.g. errors you **expect** might occur) use a return value instead. -* Try to add test cases that trigger exceptions. If an exception cannot be easily triggered using a test case then it should probably be an assertion. This is not always true (e.g. out of memory errors are exceptions, but are very hard to trigger). -* Use `D_ASSERT` to assert. Use **assert** only when failing the assert means a programmer error. Assert should never be triggered by user input. Avoid code like `D_ASSERT(a > b + 3);` without comments or context. -* Assert liberally, but make it clear with comments next to the assert what went wrong when the assert is triggered. - -## Naming Conventions - -* Choose descriptive names. Avoid single-letter variable names. -* Files: lowercase separated by underscores, e.g., abstract_operator.cpp -* Types (classes, structs, enums, typedefs, using): CamelCase starting with uppercase letter, e.g., BaseColumn -* Variables: lowercase separated by underscores, e.g., chunk_size -* Functions: CamelCase starting with uppercase letter, e.g., GetChunk -* Avoid `i`, `j`, etc. in **nested** loops. Prefer to use e.g. **column_idx**, **check_idx**. In a **non-nested** loop it is permissible to use **i** as iterator index. -* These rules are partially enforced by `clang-tidy`. +### Testing cross-platform and cross-Python + +* On your fork you can [run](https://docs.github.com/en/actions/using-workflows/manually-running-a-workflow#running-a-workflow) the Packaging workflow manually for any branch.
