### Holding multiple locks

You're allowed to take the Http2Connection lock while holding the Http2Writer lock. But not vice-versa. Because taking the Http2Writer lock can block.

systems is data "<abbr title="also called marshalling, conversion">serialization</abbr>" which is taking data from the code (Python) and converting it into something that can be sent through the network. For example, converting an object containing data from a database into a JSON object. Converting `datetime` objects into strings, etc.

Another big feature needed by APIs is data validation, making sure that the data is valid, given certain parameters. For example, that some field is an `int`,...

Nevertheless, you would probably also want to have something outside making sure to **restart Gunicorn** if necessary, and also to **run it on startup**, etc.

## Uvicorn with Workers

Uvicorn also has an option to start and run several **worker processes**.

OkHttp 4.x Change Log
=====================

## Version 4.12.0

_2023-10-16_

 *  Fix: Don't hang taking headers for HTTP 103 responses.

 *  Fix: Recover gracefully when a cache entry's certificate is corrupted.

 *  Fix: Fail permanently when there's a failure loading the bundled public suffix database.
    This is the dataset that powers `HttpUrl.topPrivateDomain()`.

   * use {@code new }{@link ArrayList#ArrayList(int) ArrayList}{@code <>(int)} directly, taking
   * advantage of <a href="http://goo.gl/iz2Wi">"diamond" syntax</a>. (Unlike here, there is no risk
   * of overload ambiguity, since the {@code ArrayList} constructors very wisely did not accept
   * varargs.)
   *
   * @param initialArraySize the exact size of the initial backing array for the returned array list
