Subject: Re: [PATCH 1/1] rebase: really just passthru the `git am` options
Date: Tue, 13 Nov 2018 15:05:36 +0000 [thread overview]
Message-ID: <00d9b0e4-dde5-c96d-76d7-42fb9ac393f8@talktalk.net> (raw)
In-Reply-To: <dc36a450680b1854abbb9bb06180001ce68c3f3b.1542112703.git.gitgitgadget@gmail.com>
Hi Johannes
Thanks for looking at this. Unfortunately using OPT_PASSTHRU_ARGV seems
to break the error reporting
Running
bin/wrappers/git rebase --onto @^^^^ @^^ -Cbad
Gives
git encountered an error while preparing the patches to replay
these revisions:
67f673aa4a580b9e407b1ca505abf1f50510ec47...7c3e01a708856885e60bf4051586970e65dd326c
As a result, git cannot rebase them.
If I do
bin/wrappers/git rebase @^^ -Cbad
I get no error, it just tells me that it does not need to rebase (which
is true)
Best Wishes
Phillip
