[PATCH] format-patch: autonumber by default

Set auto-number true by default, allowing the format.number key to be
set to 'noauto' to override this.

Interesting.  No sign-off, no defense why this is actually desirable, 
after we lived for so long without this behavior... Care to elaborate?

Doh, sorry about the Sign-off, I'll resend with.

Now, about the reason for this patch: I would say that the most common
use-case of format-patch being used to prepare multiple patches is
when one plans on sending a patchset. When format.numbering is set to
auto, single-patches will still be extracted without numbers, but
patchset will be properly numbered.

Of course, there may be cases where one doesn't want numbering (for
which there is the -N flag already), and of course we want to give the
user the choice to disable autonumbering at the config level, for
which there is the new noauto option for format.numbering.

If this explanation is good enough for you, I'll plop it in the resend
message too :)

[PATCH] format-patch: autonumber by default

[Giuseppe Bilotta]

format-patch is most commoly used for multiple patches at once when
sending a patchset, in which case we want to number the patches; on the
other hand, single-patches are not usually expected to be numbered.

The typical behavior expected by format-patch is therefore the one
obtained by enabling autonumber, which should therefore be the default.

Users that want to disable numbering for a particular patchset can do so
with the existing -N command-line switch. For users that want to change
the default behavior we provide a 'noauto' option for the
format.numbering config key.

In that case, just make it "often" and cut "most commoly" (sic) out.

I personally do not agree with this default. My usual use of
format-patch is to dump a cluster of miscellaneous patches since
"origin", and then grab the one(s) I want by title.

However, I would not be surprised to find that my use is unlike that of
most other people[1], so I am not opposed to the patch.

[1] Actually, my use has a deficiency, which is that I am often sending
2/4, without nobody having seen 1/4, on which it might actually depend.
This works in practice for me because I am often producing unrelated
janitorial patches for git. :)

So I think the goal is reasonable, but:

Thanks, the documentation updates look good to me. There are also some
updates required in t4013 (since the expected outputs for some instances
will now be numbered) and t4020 (which explicitly checks that the
default is no numbering). Probably t4020 should be modified in light of
the new default, like so:

format.numbered is a tri-state config option right now: {yes, no,  
auto}.  With this patch, if you add "[format] numbered = false" into  
your config, you still get auto-numbering.

A better way to do this might be to default both numbered and  
auto_number to true and only use auto_number is numbered is true.  Or  
turn off auto-numbering when numbering is turned off just below your  
hunk.

Either way, "noauto" is a bad idea.  It's spelled "no" or "false".

Re: [PATCH] format-patch: autonumber by default

[Brian Gernhardt]

Okay, I should wait for my test build to finish before I send the  
patch.  This doesn't build.  Nor does it pass the tests, since they  
test the old behavior.

I'll fix the build error, but I'm not inclined to spend the time  
fixing the tests since I don't actually care about changing the default.

[PATCH v2] format-patch: autonumber by default

[Brian Gernhardt]

format-patch is most commonly used for multiple patches at once when
sending a patchset, in which case we want to number the patches; on
the other hand, single patches are not usually expected to be
numbered.

In other words, the typical behavior expected from format-patch is the
one obtained by enabling autonumber, so we set it to be the default.

Users that want to disable numbering for a particular patchset can do
so with the existing -N command-line switch.  Users that want to
change the default behavior can use the format.numbering config key.

 _This_ patch changes the default and makes the config variable act
 properly.  Does not pass tests.  4014 and 4021 would have to be
 updated for the new defaults.

Grumble.  I updated git last night and this change just bit me.
Grumble.
Grumble.

It is probably a good change, but it was unexpected.
Grumble. Grumble. Grumble.

That change was in 1.6.1.1 or so, no?  Welcome to year 2009 ;-)

Out of curiousity, which version did you update _from_?

The change is a year old, and mentioned in the release notes from  
1.6.1.  If you're updating from old versions of git, it can be  
extremely useful to read the release notes as we do periodically have  
changes like this.  (In the git repository, they can be found as  
Documentation/RelNotes-*.txt)

If you wish to go back to the old default for a single project, use  
`git config format.numbered false`.  If you use the --global flag, it  
will set it for you all the time.  For a single set of unrelated  
patches being output at once, use the --no-numbered (short: -N) option  
to format-patch.

Sorry it caught you unawares.  Having it auto-number seemed like the  
most useful default.

I like it. It hasn't bitten me since I moved to imap-send, but when I
used send-email I sometimes forgot and ended up sending patch-series
without numbers.

I sent a patch for it once, but changed the default instead of making
it configurable so it got turned down.

I recall that this has been discussed (months or years ago), but I don't
recall whether there was a conclusion or whether the change was dismissed.
Did you research the ML archives?
