Git shows nothing in cmd.exe

Git shows nothing in cmd.exe

[KAVALAGIOS Panagiotis (EEAS-EXT)]

Hello,

I would like to report an issue with git. The following command:

$ git branch -a
* master
  remotes/origin/master

works fine under Cygwin terminal, but it displays nothing under cmd.exe. We are using

git version 2.21.0

and

CYGWIN_NT-10.0 XXX 3.1.4(0.340/5/3) 2020-02-19 08:49 x86_64 Cygwin

The "set CYGWIN=disable_pcon" in the cmd.exe didn't help.

Regards,

Can you please provide the output from running `where.exe git` in a
cmd.exe session, as well as the diagnostics requested in the problem
reporting guidelines below?

Given that, we'll be able to help work out what's going wrong for you.

For what it's worth, having just checked, running Cygwin Git from a
cmd.exe shell works as expected for me.

Thoughts below partly for my own reference, and partly in case anyone
else – including but not limited to Panos! – manages to take things
further before I do.

I can't see anything obviously wrong here. There's two key oddities
that might be causing problems, though:

- Cygwin is installed in `C:\Program Files\Cygwin`; that _should_
work, but it's atypical, and spaces in filenames are a common source
of problems.

- This is a relatively old installation; I've not checked anything
else, but Cygwin Git v2.21.0-1 was released in May 2019 and there have
been a bunch of updates since then. I can't remember anything with
these symptoms from that time, however.

I'm also curious about the Git configuration here, as I can see a
bunch of ways that could cause problems. I don't have the Cygwin bin
directory in my path to test this immediately, but for example `git
branch -a` will try to call a pager – `less` by default` – so I could
imagine there being a PATH problem or similar that's resulting in a
duff pager call that's eating the output.

Adam, thank you very much! You found our issue. It is the "less" command from GnuWin32 that caused the problem:

C:\>where less
C:\Program Files (x86)\GnuWin32\bin\less.exe
C:\Program Files\Cygwin\bin\less.exe

C:\>rename "C:\Program Files (x86)\GnuWin32\bin\less.exe" less-OLD.exe

C:\>cd dev\Projects\TSSO_WKS\tsso-workstation-configuration

C:\DEV\Projects\TSSO_WKS\tsso-workstation-configuration>git branch -a
* master
  remotes/origin/master

It now displays correctly the branches.

Gnuwin32 *latest* package updates seem to be 10 years ago, some nearly 20.
Suggest deleting those and using current *mingw64*/msys Windows tools instead as
they are maintained with recent security fixes.
You should also be careful with PATHs using different toolchains: switch them
completely, or layer them carefully, to avoid these issues.

You are absolutely right! This is what we are going to do. We will remove that package from our machines.

PATH is indeed yet another headache. We are trying to prepend or append entries to set correctly the behaviour by overriding other applications to no avail. Issues can still be faced.

This is why I do

@ECHO OFF

SET OLDPATH=%[PATH]
SET _CBIN=%@RTRIM[\,%@PATH[%@FULL["%~0"]]]
SET _CLBIN=%@RTRIM[\,%@PATH[%[_CBIN]]]/usr/local/bin
SET PATH=%[_CLBIN];%[_CBIN]
DO _path IN /T";" /L %[OLDPATH]
  IFF "%[_path]" == "%[_CLBIN]" THEN
    CONTINUE
  ENDIFF
  IFF "%[_path]" == "%[_CBIN]" THEN
    CONTINUE
  ENDIFF

  SET PATH=%[PATH];%[_path]
ENDDO
UNSET OLDPATH _CBIN _path

in my cygwin startup wrapper.

The regular path do contain /bin but not at the front.
