cover git-gui: GIT_ASK_YESNO/GIT_ASKPASS patches from Git for Windows

This is another set of patches from Git for Windows' fork that have been sitting there since 2010, providing cross-platform GUI helpers to ask the user a question or allow typing in a password.

This patch series was first submitted as
https://github.com/patthoyts/git-gui/pull/5 which was ignored for almost three years, then re-submitted as
https://github.com/prati0100/git-gui/pull/3 which was rejected in favor of a contribution by mail.

The patches are based on Git GUI's master branch at
https://github.com/prati0100/git-gui/.

Heiko Voigt (1):
git-gui: provide question helper for retry fallback on Windows

Johannes Schindelin (3):
git gui: set GIT_ASKPASS=git-gui--askpass if not set yet
git-gui--askyesno: allow overriding the window title git-gui--askyesno (mingw): use Git for Windows' icon, if available

PATCH 1/4 git-gui: provide question helper for retry fallback on Windows

From: Heiko Voigt <[email protected]>

Make use of the new environment variable GIT_ASK_YESNO to support the recently implemented fallback in case unlink, rename or rmdir fail for files in use on Windows. The added dialog will present a yes/no question to the the user which will currently be used by the windows compat layer to let the user retry a failed file operation.

PATCH 3/4 git-gui--askyesno: allow overriding the window title

In reply to Johannes Schindelin via GitGitGadget

From: Johannes Schindelin <[email protected]>

"Question?" is maybe not the most informative thing to ask. In the absence of better information, it is the best we can do, of course.

However, Git for Windows' auto updater just learned the trick to use git-gui--askyesno to ask the user whether to update now or not. And in this scripted scenario, we can easily pass a command-line option to change the window title.

So let's support that with the new --title <title> option.

Re: [PATCH 1/4] git-gui: provide question helper for retry fallback on Windows

The added dialog will present a yes/no question to the the user which will currently be used by the windows compat layer to let the user retry a failed file operation.

I can't find any documentation related to this environment variable. A Google search does not yield any promising results. I don't see this mentioned in the git man page either, though that is to be expected because it seems to be a Windows-only variable.

My point is, it would be nice if the commit message pointed to some sort of documentation for the environment variable. It would also help me in reviewing the patch if I know more about the variable.

Either way, some minor comments down below.

Do you really need separate functions for yes/no? I think something like

-command {exit 1}

and

-command {exit 0}

would do just fine.

Either way...

Since this seems to be a Windows-only variable, you might want to enable it only on Windows. Are there workflows on other platforms that would use this environment variable?

What is the difference between SSH_ASKPASS and GIT_ASKPASS? On my first read, I assumed SSH_ASKPASS is replaced by GIT_ASKPASS, but I might be wrong.

One minor nitpick: please add a comment at the top of the file documenting the --title option, and the usage of the program in general.

Other than that, looks good. Thanks.

Re: [PATCH 4/4] git-gui--askyesno (mingw): use Git for Windows' icon, if available

In reply to Johannes Schindelin via GitGitGadget

Since this is a git-gui dialog/prompt, why not use the git-gui icon? This will mean some uniformity between all the platforms (though I'm not sure if other platforms even use GIT_ASK_YESNO). It would also probably save you the hacks needed to find out the git-for-windows icon.

Well, there is the problem that the git-gui logo is not in any external file, and is inside git-gui.sh (as a vector image, but I'm not sure). But I'd like to at least start some discussion in this direction.

v2 cover git-gui: GIT_ASK_YESNO/GIT_ASKPASS patches from Git for Windows

In reply to Johannes Schindelin via GitGitGadget

This is another set of patches from Git for Windows' fork that have been sitting there since 2010, providing cross-platform GUI helpers to ask the user a question or allow typing in a password.

This patch series was first submitted as
https://github.com/patthoyts/git-gui/pull/5 which was ignored for almost three years, then re-submitted as
https://github.com/prati0100/git-gui/pull/3 which was rejected in favor of a contribution by mail.

The patches are based on Git GUI's master branch at
https://github.com/j6t/git-gui/.

Changes since v1:

* Rebased to current master branch of Git GUI, resolving merge conflicts.
* Dropped double empty line.
* Skip yes/no functions in favor of inline exit 0/exit 1.
* The --title option is now documented in the git-gui--askyesno script.

PATCH v2 1/4 git-gui: provide question helper for retry fallback on Windows

From: Heiko Voigt <[email protected]>

Make use of the new environment variable GIT_ASK_YESNO to support the recently implemented fallback in case unlink, rename or rmdir fail for files in use on Windows. The added dialog will present a yes/no question to the the user which will currently be used by the windows compat layer to let the user retry a failed file operation.

PATCH v2 3/4 git-gui--askyesno: allow overriding the window title

In reply to Johannes Schindelin via GitGitGadget

From: Johannes Schindelin <[email protected]>

"Question?" is maybe not the most informative thing to ask. In the absence of better information, it is the best we can do, of course.

However, Git for Windows' auto updater just learned the trick to use git-gui--askyesno to ask the user whether to update now or not. And in this scripted scenario, we can easily pass a command-line option to change the window title.

So let's support that with the new --title <title> option.

Thank you very much!

Let's keep your patch separate, to give you full credit, and to keep Heiko's patch as close to the original that has survived in Git for Windows for so long.

Which "this dialog box" do you mean here? The old code looks like a usual Tk main window to me.

Sorry for the late reply. As you suspected (seeing as you changed it when integrating sthe patch into your tree), it was just an artifact of history.

This patch entered Git for Windows back in the msysGit days, in
https://github.com/msysgit/git/commit/1644f8ea0159 (2010-07-23), according to my records that corresponds to the v1.7.2.3.msysgit.0 timeframe, when this block was surrounded by similar, [gitexec]-using code blocks.

The patch remained virtually unchanged until
https://github.com/git-for-windows/git/commit/076c4bc42171 (2025-06-16), which still made it into v2.50.0.

Starting with https://github.com/git-for-windows/git/commit/ab11df9a3899
(2025-08-05), this block's context changed, and I must have changed the block itself in reaction to it in Git for Windows (but I failed to miss it before sending the patch you reviewed). The patch made it into v2.51.0-rc0 in that new shape, using [file join ...] instead of [gitexec].

Luckily, you made the very same adjustment before committing it as
https://github.com/git/git/commit/aeaabebc1a10 (2025-08-28), so all is good.

Ciao,
Johannes
