[PATCH 0/3] "git notes remove" updates

[Junio C Hamano]

I wanted to do a bit better than

	for sha1 in ... list of old commit objects
	do
		git notes --ref refs/notes/amlog remove $sha1
	done

to remove old entries in my "where did this commit come from" database.

Junio C Hamano (3):
  notes remove: allow removing more than one
  notes remove: --missing-ok
  notes remove: --stdin reads from the standard input

[PATCH 1/3] notes remove: allow removing more than one

[Junio C Hamano]

While "xargs -n1 git notes rm" is certainly a possible way to remove notes
from many objects, this would create one notes "commit" per removal, which
is not quite suitable for seasonal housekeeping.

Allow taking more than one on the command line, and record their removal
as a single atomic event if everthing goes well.

Even though the old code insisted that "git notes rm" must be given only
one object (or zero, in which case it would default to HEAD), this
condition was not tested. Add tests to handle the new case where we feed
multiple objects, and also make sure if there is a bad input, no change
is recorded.

You're not really testing that this removes the correct notes. Actually,
you're not even testing that this removes only 2 notes when there are
more than 2, are you? I might be a bit fussy, though. I like the feature
in general:

 git notes remove $(git rev-list <fancy-rev-spec>)

rocks :)

Although "notes remove" could grok a rev-spec and dwim --do-walk, come
to think of it. Would be even more gittish.

In the test vector, there are only two notes, and I am testing removal of
multiple.  What do you want me to do?  Test removing one and make sure the
other one survives ;-)? 

Patches on top of it is very welcome, but I wouldn't bother.

The test has two notes because it was created when remove would remove
one note at a time only, and the test made sure it did not remove the
other one (!).

If you want a meaningful test which tests that "git notes remove A B"
removes exactly 2 notes (not more) you need to add another note first.
Otherwise it could be that your new code simply nukes the notes tree. (I
know it does not, but only by looking at the source; this test does not
check it.)

Checking that it actually removes *those* 2 notes would give extra
credit but may not be necessary (since we know it removes the correct
one in single mode).

> Patches on top of it is very welcome, but I wouldn't bother.

Is that the kind of response you accept from submitters to your (valid)
requests that they provide negative tests in addition to positive ones?

I don't mind helping out with a test patch (later this UTC day) but I'm
concerned about the attitude someone may read into this and may want to
follow as an example. In terms of code-with-test habits, I would claim
that git.git is really an exemplary standard to follow (and to keep).

Cheers,
Michael

Fair enough.  Here is an incremental update to be squashed in.

I notice that "notes list <commit>" and "notes list | grep <commit>" give
quite different results, and "notes list <commit1> <commit2>..." does not
even work at all. Probably the "notes" interface was done with interactive
use in mind without realizing the need for batch operations.

[PATCH 2/3] notes remove: --missing-ok

[Junio C Hamano]

Depending on the application, it is not necessarily an error for an object
to lack a note, especially if the only thing the caller wants to make sure
is that notes are cleared for an object.  By passing this option from the
command line, the "git notes remove" command considers it a success if the
object did not have any note to begin with.

Re: [PATCH 2/3] notes remove: --missing-ok

[Junio C Hamano]

Just FYI, I'll rename this to --ignore-missing to match other commands in
the version I am going to queue in 'pu'.

[PATCH 3/3] notes remove: --stdin reads from the standard input

[Junio C Hamano]

Teach the command to read object names to remove from the standard
input, in addition to the object names given from the command line.

So that makes 4/3 to be... ;)

I'm torn between asking for a rev-list interface and being happy with
--stdin. I guess we have other places where we allow lists of objects in
argv and stdin (instead of rev-list), and since this targets all kinds
of objects, it's more natural as is (than with with the rev-list interface).

Wouldn't strbuf_rtrim (or even strbuf_trim) be useful here?

Manipulating only a copy of the len parameter while changing the strbuf
itself raised warning flags, though it is correct as-is because you
never actually use sb.len.

Using strbuf_trim is shorter, easier to read, and will helpfully eat any
extraneous whitespace, too.

Thanks for noticing.

I just mimicked what was done to the result of strbuf_getwholeline() in
other places (I think from revision.c but I am not sure).

An incremental correction, relative to what I had in 'pu' overnight, looks
like this.

I am tempted to say that other callsites should be "upgraded" to
strbuf_trim. Is there any reason we should not be liberal in accepting
something like:

  echo "  refs/heads/foo  " | git rev-list --stdin

?

I guess for pathspecs we would want to be more literal, though, so maybe
it is a stupid idea.

Thanks. BTW, I was too busy picking this one nit to mention that the
general direction of the series is a nice improvement. :)

[PATCH 4/3] show: --ignore-missing

[Junio C Hamano]

Instead of barfing, simply ignore bad object names seen in the
input. This is useful when reading from "git notes list" output
that may refer to objects that have already been garbage collected.

Signed-off-by: Junio C Hamano <gitster@pobox.com>

 * This would let me do something like

	git notes list |
        sed -e 's/. *//' | # strip note-blob
	git show --format='%ci %H ...' --ignore-missing --stdin |
        ... perhaps sort by commit date, filter, etc... |
        git notes remove --stdin --ignore-missing

   Perhaps "git notes list --target-only" can be added to remove the
   need for the second "sed" in the pipeline.
