## Developing

If you already cloned the <a href="https://github.com/tiangolo/fastapi" class="external-link" target="_blank">fastapi repository</a> and you want to deep dive in the code, here are some guidelines to set up your environment.

### Virtual environment with `venv`

You can create an isolated virtual local environment in a directory using Python's `venv` module. Let's do this in the cloned repository (where the `requirements.txt` is):

	if c == nil {
		return
	}
	c.recordPluginMetrics = flag
}

// Clone creates a copy of CycleState and returns its pointer. Clone returns
// nil if the context being cloned is nil.
func (c *CycleState) Clone() *CycleState {
	if c == nil {
		return nil
	}
	copy := NewCycleState()
	// Safe copy storage in case of overwriting.
	c.storage.Range(func(k, v interface{}) bool {

        assertNotSame(
                activeProfilesOrig,
                activeProfilesClone,
                "The list of active profiles should have been cloned too but is same");
    }

    @Test
    void testCloneWithBaseDir() throws Exception {
        File f = getFileForClasspathResource("canonical-pom.xml");
        MavenProject projectToClone = getProject(f);
