[PATCH 0/2] git-send-email: add --transfer-encoding option for conversion to specified encoding

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Paolo Bonzini <pbonzini@xxxxxxxxxx>

The thread at http://thread.gmane.org/gmane.comp.version-control.git/257392
details problems when applying patches with "git am" in a repository with
CRLF line endings.  In the example in the thread, the repository originated
from "git-svn" so it is not possible to use core.eol and friends on it.

Right now, the best option is to use "git am --keep-cr".  However, when
a patch create new files, the patch application process will reject the
new file because it finds a "/dev/null\r" string instead of "/dev/null".

The problem is that SMTP transport is CRLF-unsafe; "git am --keep-cr" is
mostly working by chance and it would be very problematic to have a "git
am" workflow in a repository with mixed LF and CRLF line endings.  It is
more robust to forgo readable patch files[1] and use the quoted-printable
transfer enconding.  This series adds an option and configuration key
to git-send-email that lets it automatically produce quoted-printable
or base64 messages.

[1] A useful oneliner to decode quoted-printable files is the following:
    perl -pe 'use MIME::QuotedPrint; $_=MIME::QuotedPrint::decode($_);'
