Cannot determine linuxbrew version: Homebrew >=1.4.0 (shallow or no git repository)

[jacktose]

• ran a brew command and reproduced the problem with multiple formulae?
  not about formulae
• ran brew update and can still reproduce the problem?
• ran brew doctor, fixed all issues and can still reproduce the problem?
  Fixed everything I have access to. Don't think it's related.
• ran brew config and brew doctor and included their output with your issue?

To help us debug your issue please explain:

• What you were trying to do (and why)
  Update linuxbrew to latest version.
• What happened (include command output)
  Brew reports Homebrew >=1.4.0 (shallow or no git repository)

$ brew update
Already up-to-date.
$ brew --version
Homebrew >=1.4.0 (shallow or no git repository)
Homebrew/homebrew-core (git revision 40a1db; last commit 2018-06-20)

• What you expected to happen
  Homebrew = 1.6.9 maybe? That's current.
• Step-by-step reproduction instructions (by running brew commands)

$ brew --version
Homebrew >=1.4.0 (shallow or no git repository)
Homebrew/homebrew-core (git revision 40a1db; last commit 2018-06-20)

• brew config and brew doctor output:

$ brew update
Already up-to-date.

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:
  /netops/local/bin/python2-config
  /netops/local/bin/python3-config
  /netops/local/bin/php-config
  /bin/pkg-config
  /bin/freetype-config
  /bin/pcre-config
  /bin/libpng-config
  /bin/krb5-config
  /bin/net-snmp-config
  /bin/libgcrypt-config
  /bin/gpg-error-config

Warning: An outdated version (1.8.3.1) of Git was detected in your PATH.
Git 1.8.5 or newer is required to perform checkouts over HTTPS from GitHub and
to support the 'git -C <path>' option.
Please upgrade:
  brew install git

Warning: /usr/bin occurs before /data/shared/lusers/jacktose/.linuxbrew/bin
This means that system-provided programs will be used instead of those
provided by Homebrew. The following tools exist at both paths:
  ex
  rview
  rvim
  view
  vim
  vimdiff
  vimtutor
  xxd

Consider setting your PATH so that /data/shared/lusers/jacktose/.linuxbrew/bin
occurs before /usr/bin. Here is a one-liner:
  echo 'export PATH="/data/shared/lusers/jacktose/.linuxbrew/bin:$PATH"' >> ~/.bash_profile

Warning: Homebrew's bin was not found in your PATH.
Consider setting the PATH for example like so
  echo 'export PATH="/data/shared/lusers/jacktose/.linuxbrew/bin:$PATH"' >> ~/.bash_profile

Warning: Some installed formulae are missing dependencies.
You should `brew install` the missing dependencies:
  brew install berkeley-db bzip2 expat gdbm libbsd libffi libyaml ncurses openssl perl python readline ruby sqlite xz zlib

Run `brew missing` for more details.

Ohhhh. Just found this:

# test-bot does environment filtering itself
if [[ -z "$HOMEBREW_NO_ENV_FILTERING" && "$1" != "test-bot" ]]
then
PATH="/usr/bin:/bin:/usr/sbin:/sbin"

Is it intended that *brew doesn't respect the regular system path (by default)?
I'm on a machine (as you can guess from my brew doctor) with a really non-standard path setup. I don't know the intention of the above lines, but it seems that brew is just shooting itself in the foot in this case.

[sjackman]

Filtering the environment by default (specifically PATH) is a new-ish feature (a few months old). It helps in many cases where users have weird broken executables in their PATH. It's more reliable and reproducible to use system executables and brewed executables, and avoid the user's PATH. There's a few bugs though. Two in particular are that by default it uses /usr/bin/git rather than brewed git and /usr/bin/curl rather than brewed curl, which causes issues like this when those system executables are too old. When the host executables are too old, it should use the brewed executables. That's not happening currently though, which is a bug. If you're interesting in submitting a patch to fix this issue, I can point you in the right direction.

[jacktose]

I'd be happy to take a crack at it.
Is it not as simple as adding the brew path to the front of the path?

(I'll just export HOMEBREW_NO_ENV_FILTERING=1 on this machine for now. Thanks!)

[sjackman]

Is it not as simple as adding the brew path to the front of the path?

It would be, and somewhere in the history of pull requests, there's a PR opened by me that was closed without being merged. We try to keep Linuxbrew's behaviour similar to Homebrew's behaviour, and Homebrew does not do that.

Homebrew and Linuxbrew do have a configuration option HOMEBREW_FORCE_BREWED_CURL=1, but there's no corresponding option HOMEBREW_FORCE_BREWED_GIT. Would you be up for implementing that option?

There's also the auto-detected variable HOMEBREW_SYSTEM_CURL_TOO_OLD, which enables HOMEBREW_FORCE_BREWED_CURL=1 automatically. If there were the corresponding feature HOMEBREW_SYSTEM_GIT_TOO_OLD, it would resolve this bug.
