I think it also changes the output of rebase -i/-r, cherry-pick and revert. Fixing the latter two is easy, it will be trickier to fix the former. Rebase -i/-r/-m already print 'Rebasing (n/m)' as they apply each patch and reuses the same line if --verbose is not given to save terminal space where they are picking a large number of commits. I can see why you want this output when rebasing after pulling, I'm not sure we necessarily want to change the output of rebase -i/-m/-r though. Maybe we can add a member to struct replay_opts that is set by pull and rebase --apply or maybe we should print the commit subject when --verbose is set. I'm not really sure at the moment - I've cc'd Elijah and dscho to see if they have any thoughts > linelen is taken from builtin/am.c. A minor point - the sequencer uses the subject as given by 'log --pretty=%s' when creating the todo list and I think that is probably what we should be printing (both here and for am). This is subtly different from using linelen() as --pretty=%s unwraps all the lines before the first empty line of the commit message so line one line two commit message body would appear as 'line one line two' whereas linelen() just gives 'line one' Best Wishes Phillip > sequencer.c | 12 ++++++++++++ > 1 file changed, 12 insertions(+) > > diff --git a/sequencer.c b/sequencer.c > index 6fd2674632..5e315eda1c 100644 > --- a/sequencer.c > +++ b/sequencer.c > @@ -1442,6 +1442,14 @@ static int write_rebase_head(struct object_id *oid) > return 0; > } > > +/** > + * Returns the length of the first line of msg. > + */ > +static int linelen(const char *msg) > +{ > + return strchrnul(msg, '\n') - msg; > +} > + > static int do_commit(struct repository *r, > const char *msg_file, const char *author, > struct replay_opts *opts, unsigned int flags, > @@ -1458,6 +1466,10 @@ static int do_commit(struct repository *r, > "from '%s'"), > msg_file); > > + if (!opts->quiet) > + fprintf_ln(stdout, _("Applying: %.*s"), > + linelen(sb.buf), sb.buf); > + > res = try_to_commit(r, msg_file ? &sb : NULL, > author, opts, flags, &oid); > strbuf_release(&sb); >

This makes the output of "git pull --rebase" look as if using the apply backend. Signed-off-by: Leah Neukirchen <leah@vuxu.org> --- I noticed that the new "merge" rebase backend does not print lines ala "Applying: reticulate the splines" anymore. I found these useful when using "git pull --rebase", as one easily saw which unpushed patches were in the tree. (Also, eliminated patches were not printed anymore, but that is a special thing about our workflow, where many committers can do exactly the same trivial patches often.) I found do_commit to be the best place to put this, but I'm not super familiar with the Git code base; perhaps this also prints in other invocations where it rather shouldn't. linelen is taken from builtin/am.c. sequencer.c | 12 ++++++++++++ 1 file changed, 12 insertions(+)
