Bug fixes should be accompanied by a test that shows that the bug has been fixed. If the bug fix is fixing something that is covered by a test in the C Python test suite (Src\StdLib\Lib\test) and that test is not currently enabled, try enabling the test in Src\IronPythonTest\Cases*.ini depending on the type of test it is.

Most PR's will not be accepted if there is not a test included.

• We have a .editorconfig file with the coding conventions used in the project. Please use an editor that honors these settings.

• Use .NET Framework conventions for all identifiers.

  • There is no specific guideline for naming private fields in this document; we prefix field names with underscores (e.g. private string _fooBar;) so that use of the fields is easily distinguishable as a field access as opposed to a local variable access.
  • If you're not sure about some convention, try to find out in the rest of the IronPython code or ask in the list.

• Use /*!*/ for method parameters and instance fields that should never be null. Spec# annotations.

• Do not use public fields (Base::algorithm, buffer). Use properties if it is necessary to expose the field or private/internal visibility otherwise.

• Use readonly if the field is not mutated after the object is constructed.

• Auto properties are to be used when possible instead of private fields with wrapping properties.

• String interpolation should use used instead of calls to String.Format

The following commands will build and run all the tests that are required to pass. If you get any failures, do report them to the mailing-list to see if they are expected or not. This command can usually run without any failures.

./make.ps1 test-all
