## Compiler {#compiler}

## Assembler {#assembler}

Previously, large builds could see 100%+ build time increase from enabling PGO.
In Go 1.23, overhead should be in the single digit percentages.

# Démarrage

Le fichier **FastAPI** le plus simple possible pourrait ressembler à cela  :

```Python
{!../../../docs_src/first_steps/tutorial001.py!}
```

Copiez ce code dans un fichier nommé `main.py`.

Démarrez le serveur :

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

        addPart(Part.createFormData(name, filename, body))
      }

      /** Add a part to the body. */
      fun addPart(part: Part) =
        apply {
          parts += part
        }

      /** Assemble the specified parts into a request body. */
      fun build(): MultipartBody {
        check(parts.isNotEmpty()) { "Multipart body must have at least one part." }

 * ### Paths and Queries should decompose
 *
 * Neither of the built-in URL models offer direct access to path segments or query parameters.
 * Manually using `StringBuilder` to assemble these components is cumbersome: do '+' characters get
 * silently replaced with spaces? If a query parameter contains a '&', does that get escaped?

- [`KT-53687`](https://youtrack.jetbrains.com/issue/KT-53687) Don't trigger npm and yarn related tasks if it not relevant for assemble
- [`KT-49915`](https://youtrack.jetbrains.com/issue/KT-49915) KJS / Gradle: Gradle build cache miss because of absolute path in `KotlinJsIrLink.filteredArgumentsMap`

Il démarrera alors le serveur avec votre code **FastAPI**, s'arrêtera à vos points d'arrêt, etc.

Voici à quoi cela pourrait ressembler :

Si vous utilisez Pycharm, vous pouvez :

- Ouvrir le menu "Run".
- Sélectionnez l'option "Debug...".
- Un menu contextuel s'affiche alors.

            allowEmpty = false,
            description = "Which performance test to run. Should be the fully qualified class name dot (unrolled) method name. E.g. org.gradle.performance.regression.java.JavaUpToDatePerformanceTest.up-to-date assemble (parallel true)"
        )
        text("testJavaVersion", "17", display = ParameterDisplay.PROMPT, allowEmpty = false, description = "The java version to run the performance tests, e.g. 8/11/17")
        select(

command line parameters on the first run: 
    
    ./gradlew -Dhttp.socketTimeout=60000 -Dhttp.connectionTimeout=60000

## Important gradle tasks

- `clean` - clean build results
- `dist` - assembles the compiler distribution into `dist/kotlinc/` folder
- `install` - build and install all public artifacts into local maven repository
- `coreLibsTest` - build and run stdlib, reflect and kotlin-test tests
