Re: git rebase --continue after solving conflicts doesn't work anymore

["Sebastián Mancilla" <smancill.m@gmail.com>]

My system is macOS Mojave 10.14.2. I normally use Git from Homebrew (currently
Git 2.20.1).

I investigated this further, and I think I found the problem on my end.

When I actually run "git rebase --interactive <commit>" from the terminal,
everything works fine.

But almost every time I start my rebases from inside "tig" [0], for which I
have this mapping:

        bind main R <git rebase -i %(commit)

tig will exit after running that command, and then I normally continue working
on the rebase from the shell. And it is when I start the rebase this way that
"git rebase --continue" fails after solving conflicts.

Second, I have tig installed with the Nix package manager [1], which shows

        $ ~/.nix-profile/bin/tig --version
        tig version 2.4.1
        ncursesw version 6.1.20180127
        readline version 6.3

So, I decided to try with tig from Homebrew, and then the problem
doesn't happen.
The Hombrew version of tig shows:

        $ /usr/local/bin/tig --version
        tig version 2.4.1
        ncurses version 5.7.20081102
        readline version 8.0

I will keep using tig from Homebrew to avoid issues for now.


In summary, the problem only happens when I start the rebase from inside tig,
but only when tig is the version from the Nix package manager, which has
different dependencies than the Homebrew version of tig.
And it happens for Git 2.20.x and master. Git <= 2.19.x works fine.


I also did bisect Git (I never though I would be bisecting Git itself).
It landed in this commit: 4d010a757c (sequencer: use read_author_script(),
2018-10-31).

And the content of .git/rebase-merge/author-script is always the same:

        GIT_AUTHOR_NAME='Sebastián Mancilla'
        GIT_AUTHOR_EMAIL='smancill@jlab.org'
        GIT_AUTHOR_DATE='@1550530007 -0300
