Subject: Re: [PATCH] Update "gc" behavior in commit, merge, am, rebase and index-pack
Date: Sat, 12 May 2012 15:18:24 +0700 [thread overview]
Message-ID: <CACsJy8BXXrze-0n++YenDERfi=z26L1P_06XjZLFeeMuuLgg8w@mail.gmail.com> (raw)
In-Reply-To: <1336810134-3103-1-git-send-email-pclouds@gmail.com>
(CCing Fernnando and complaining about send-email)
I accidentally put buccia@@repnz.net instead of one @. There were
warnings in the jungle that send-email spit out:
Use of uninitialized value $cc in string eq at
/home/pclouds/opt/git/libexec/git-core/git-send-email line 983.
Use of uninitialized value $cc in quotemeta at
/home/pclouds/opt/git/libexec/git-core/git-send-email line 983.
W: unable to extract a valid address from: Fernando Vezzosi <buccia@@repnz.net>
W: unable to extract a valid address from: Fernando Vezzosi <buccia@@repnz.net>
but it's really hard to see that. Maybe send-email should not allow me
to send in this case (unless I give --force), or make the warnings
more outstanding?
