The `--no-cache-dir` is only related to `pip`, it has nothing to do with Docker or containers.

    ///

    The `--upgrade` option tells `pip` to upgrade the packages if they are already installed.

    Because the previous step copying the file could be detected by the **Docker cache**, this step will also **use the Docker cache** when available.

title: "Go, Backwards Compatibility, and GODEBUG"

<!--
This document is kept in the Go repo, not x/website,
because it documents the full list of known GODEBUG settings,
which are tied to a specific release.

## Introduction {#intro}

Go's emphasis on backwards compatibility is one of its key strengths.
There are, however, times when we cannot maintain complete compatibility.

    int length = end - start;
    if (length <= 0 || length > 3) {
      throw new NumberFormatException();

    // Disallow leading zeroes, because no clear standard exists on
    // whether these should be interpreted as decimal or octal.
    if (length > 1 && ipString.charAt(start) == '0') {
      throw new NumberFormatException();
    }
    int octet = 0;

- We limited the number of drives to 16 for erasure set because, erasure code shards more than 16 can become chatty and do not have any performance advantages. Additionally since 16 drive erasure set gives you tolerance of 8 drives per object by default which is plenty in any practical scenario.
