[PATCH] builtin/send-pack: populate the default configs

[PATCH] builtin/send-pack: populate the default configs

[Masaya Suzuki]

builtin/send-pack didn't call git_default_config, and because of this
git push --signed didn't respect the username and email in gitconfig in
the HTTP transport.

Makes sense.  I wonder if this was deliberate (i.e. we had some
reason not wanting to be affected by some _other_ configuration
items and refraining from doing the default-config was the way to
implement it), but I do not think of a reason offhand.

Will queue.  Thanks.

[PATCH] builtin/send-pack: report gpg config errors

[Stefan Beller]

Any caller except of git_gpg_config() except the one in send_pack_config()
handles the return value of git_gpg_config(). Also handle the return value
there.

There was no need for other configuration to be loaded and signing
pushes is the first that needs repository configuration.

Looking at 68c757f2199 (push: add a config option push.gpgSign for default
signed pushes, 2015-08-19) further, maybe we want to also have this?

Thanks,
Stefan

Drop the first "except"?

Also: s/Any caller/All callers/

The other callers do

	int status;

	if (!strcmp(k, "key.i.handle")) {
		...
		return ...;
	}
	return git_gpg_config(k, v, NULL);

or

	int status;

	if (!strcmp(k, "key.i.handle")) {
		...
		return ...;
	}

	status = git_gpg_config(k, v, NULL);
	if (status)
		return status;
	...

Should this do the same?  That way, if config_fn_t learns to return
more fine-grained errors (e.g. a new return value of -2 or 1) then it
would be propagated.

Thanks,
Jonathan

Do you have a set of commands I can run to reproduce this?  Bonus
points if they're in the form of a patch to t/, but commands I can
manually run would be fine, too.

send-pack is not a command served by a daemon so this is less
potentially scary than the corresponding potential change to
upload-pack or receive-pack.  Some configuration this brings in:

- core.askpass: allows specifying an arbitrary command to use to
  ask for a password.  Respecting this setting should be very useful,
  even if it would be scary in a daemon.

- core.pager: allows specifying an arbitrary command to use as a
  pager, if pagination is on (but it shouldn't be on).
- core.logallrefupdates: whether to create reflogs for new refs
  (including new remote-tracking refs). Good.
- core.abbrev: what length of abbreviations to use when printing
  abbreviated object ids (good).
- core.compression, core.packedgitwindowsize, etc: pack generation
  tunables (good).
- advice.*: would allow us to make "git push" produce configurable
  advice (good!)
- etc

So it looks like a very good change.  Thanks for writing it.

except builtin/log, which I followed. :/

This conflicts with Masayas patch, that has a return of the
standard options.

This looks like a good idea.

Will send a follow up patch.

This summary probably ought to be in the commit message itself (plus
additional commentary implied by the ending "etc."). It's exactly the
sort of information someone looking at this patch in the future will
want to know to feel assured that such behavior changes were taken
into account by the patch author.
