Let's remove all (or the largest) diffs from gcc-cvs@

TL;DR: See subject.  Verbosity follows.

The git transition is mostly for the better.  Thanks to those
investing time and effort.  There's always fallout.  Here's one

In the distant past with svn, there messages to gcc-cvs@ were
somewhat like git show --stat, i.e. without the actual changes:

Author: gccadmin
Date: Wed Dec 25 00:16:22 2019
New Revision: 279730

Daily bump.


Now after the git transition, patches *always* come with a diff, as below.


commit d8998708ca316249e475d139c89ae7d169e64d34
Author: GCC Administrator <>
Date:   Wed Jan 15 00:16:26 2020 +0000

    Daily bump.

(No, not just the daily bump, I just wanted to avoid a person
being pointed out and had no commits myself "within reach".)

Why the diff?  I don't remember the absence of a diff being a
problem in the svn era (or at least wasn't argued much on the
mailing lists).

Compare also to traffic on binutils-cvs@ and gdb-cvs@, where
there *are* diffs posted, but apparently there's a size limit; I
see "[diff truncated at 100000 bytes]" for a post on gdb-cvs.
Still, I very much prefer no diff at all.

Does someone actually (not theoretically) have a need that is
fulfilled by those diffs?

Can we remove them altogether?
If not, can we cap the messages at a size limit?

Note: I'm aware of the discussion regarding limiting posts for
certain branches to gcc-cvs; that's incidental.  Note also that
my own needs are handled by means of procmail, I was just
bothered enough to bring it up, and less email traffic on
sourceware means more bandwidth for actual commit traffic. :)
