Can't use "Git add -i"

Question

Trying to patch a file to last commit, so I run "git add -p" and "git add -i", but received the following error:

That is:

D:\Working\test>git add-i
      0 [main] perl 375 child_copy: stack write copy failed, 6xFFFFC480..8x10000000e, done 6444523849, windows pid 15080, Win32 error 5

Tried to uninstall and install Git, but the issue still persist.

Answer 1

Thanks to comment of @torek, I managed to use the commands after installing Per

You should not have.

1. The latest versions of Git for Windows no longer use Perl for git add (mingw64/libexec/git-core/git-add.exe). This is rewritten in C since Git 2.25, Q1 2020.
2. perl.exe is part of the Git for Windows distribution: make sure your %PATH% includes C:\path\to\Git\usr\bin

There is no need to install Perl for Git to run.

2 years later (Q1 2022), With Git 2.36 (Q2 2022), there are still finishing touches to C rewrite of "git add -i"^(man) in single-key interactive mode.

terminal: restore settings on SIGTSTP

^{Signed-off-by: Phillip Wood}

If the user suspends git while it is waiting for a keypress reset the terminal before stopping and restore the settings when git resumes.
If the user tries to resume in the background print an error message (taking care to use async safe functions) before stopping again.
Ideally we would reprint the prompt for the user when git resumes but this patch just restarts the read().

The signal handler is established with sigaction() rather than using sigchain_push() as this allows us to control the signal mask when the handler is invoked and ensure SA_RESTART is used to restart the read() when resuming.
