[wtnb75]

Please note we will close your issue without comment if you delete, do not read or do not fill out the issue checklist below and provide ALL the requested information. If you repeatedly fail to use the issue template, we will block you from ever submitting issues to Homebrew again.

Please always follow these steps:

• Confirmed this is a problem with running a brew command and not brew installing or the post-install behaviour of one or more formulae? If it's a formulae-specific problem please file this issue at the relevant tap e.g. for Homebrew/homebrew-core https://github.com/Homebrew/homebrew-core/issues/new
• Ran brew update and retried your prior step?
• Ran brew doctor, fixed all issues and retried your prior step?
• Ran brew config and brew doctor and included their output with your issue?

To help us debug your issue please explain:

• run brew update behind proxy
• got fatal: unable to access 'https://github.com/Homebrew/brew.git/': Failed to connect to github.com port 443: Operation timed out
  • git command failed (/Applications/Xcode.app/Contents/Developer/usr/bin/git fetch --tags --force -q origin refs/heads/master:refs/remotes/origin/master)

Features

• https://github.com/Homebrew/brew/blob/master/bin/brew#L91
  • there is no https_proxy in FILTERED_ENV (but http_proxy)
    • see: curl doesn't respect "http_proxy" environment variable when brew-installing #3494 / 63408a1
  • please add https_proxy, ftp_proxy, no_proxy

We will close this issue or ask you to create a pull-request if it's something we're not actively planning to work on.

Note that the curl manpage lists HTTPS_PROXY rather than https_proxy (although both seem to work in my testing) so FILTERED_ENV should probably also include capitalized versions.
