[PATCH v4 0/4] commit: support commit.verbose and --no-verbose

[PATCH v4 0/4] commit: support commit.verbose and --no-verbose

[caleb]

This patch allows people to set commit.verbose to implicitly send
--verbose to git-commit. It also introduces --no-verbose to override the
configuration setting.

This version incorporates changes suggested by Eric Sunshine, Duy
Nguyen, and Jeremiah Mahler.

It introduces several cleanup patches to t/t7505-commit-verbose.sh to
bring it closer to the current state of the tests as Eric has explained
them to me, then adds the verbose config and --no-verbose flag.

Since the last version of this patch
(http://marc.info/?l=git&m=140113063517118&w=2), I've made the following
changes:

* Remove the $PWD => $(pwd) change, as it was a misunderstanding of
  t/README (Thank you to Johannes and David for pointing that out and
  clarifying)
* Use consistent test naming (Thanks to Jeremiah)
* Switch from <<-EOF to <<-'EOF' without manual escaping in write_script
  calls for the test editors check-for-diff and check-for-no-diff. The
  proposed <<-\EOF syntax did not properly prevent the parameter
  substitution on my machine, as both Eric and the documentation
  suggested it should, but the quoted version seems to work fine.
  (Thanks to Eric)
* Fix extra test_set_editor invocations and broken %%-chains created as a result
  of the test_set_editor changes. (Thanks again to Eric)

[PATCH v4 1/4] commit test: Use test_config instead of git-config

[caleb]

Some of the tests in t/t7507-commit-verbose.sh were still using
git-config to set configuration. Change them to use the test_config
helper.

It is probably something dumb on my part but for some reason I cannot
apply this patch using 'git am'.  After I save the patch to a Maildir
from Mutt and run git am...

  jeri@hudson:~/git$ ./git-am ct1.patch
  Applying: commit test: Use test_config instead of git-config
  fatal: corrupt patch at line 15
  Patch failed at 0001 commit test: Use test_config instead of git-config
  The copy of the patch that failed is found in:
     /home/jeri/git/.git/rebase-apply/patch
  When you have resolved this problem, run "git am --continue".
  If you prefer to skip this patch, run "git am --skip" instead.
  To restore the original branch and stop patching, run "git am --abort".
  jeri@hudson:~/git$

The second patch in the series applies fine.  And I have applied other
patches this way without issue.  Can anyone confirm this problem?

I assume that you're running it against master?

I rebased the branch yesterday, but I'll give it another shot. Obviously I
didn't use git-am, but I can try that.

Thanks for checking.  Unfortunately the problem persists for me.

It seems to be related to there not being a space at the left most part
of the patch.  It is just a tab with no space.  So 'git am' has a
problem because it is expecting to remove a space and there isn't one.
See the attached screenshots with tabs highlighted.

How are you preparing your patches.  'git format-patch' with a 'git
send-email'?

I'm so glad you asked, because I've just been muddling through this.

I've been generating the cover page variously with request-pull or diff
--stat, then running a command like this, with --cc arguments added from
a list I've been keeping of people who respond to the threads:

    git send-email --compose --to=git@vger.kernel.org --thread \
        [--cc ...] --no-chain-reply origin/master...

Then I manually edit the subjects to add the version to the [PATCH N/M]
portions. I haven't been using format-patch.

It's interesting that only the first patch isn't applying. I'd love to
hear a better way.

It sounds like you are doing too much work.

After I make a series of commits I run format-patch.  This example has 2
patches (-2).  I like --thread, although it seems to work fine without
it.  And --reroll-count will automatically do your N/M numbering for
you.  It also generates a cover letter which you can then edit by hand.
All the patches will be named v3-* in this case.

  git format-patch --reroll-count=3 --cover --thread -2

Then I can send the whole patch series using send-email.

  git send-email --to=caleb --cc=git --cc=junio v3-*

Felipe Contreras has a good writeup [1] on how to setup aliases with Mutt so
you don't have to type the full email every time.

[1]: http://felipec.wordpress.com/2009/10/25/git-send-email-tricks/

I recently setup Mutt with Offlineimap [2] and Msmtp.  This is an
awesome setup too.  Not patch related, but it makes the email part
easier.

Jeremiah,

That looks great. Since I'm not seeing any more feedback on the code for this
set of patches, I'll go ahead and send up another set.

Thank you for those pointers.

[PATCH v4 2/4] commit test: Use write_script

[caleb]

Use write_script from t/test-lib-functions.sh instead of cat, shebang,
and chmod. This protects us from potential shell meta-characters in the
name of our trash directory, which would be interpreted if we set
$EDITOR directly.

[PATCH v4 3/4] commit test: test_set_editor in each test

[caleb]

t/t7507-commit-verbose.sh was using a global test_set_editor call to
build its environment.

Improve robustness against global state changes by having only tests
which intend to use the $EDITOR to check for presence of a diff in the
editor set up the test-editor to use check-for-diff rather than relying
upon the editor set once at script start.

Besides being in line with current practices, it also allows the tests
which set GIT_EDITOR=cat manually to avoid using a subshell and simplify
their logic.

[PATCH v4 4/4] commit: support commit.verbose and --no-verbose

[caleb]

Add a new configuration variable commit.verbose to implicitly pass
`--verbose` to `git-commit`. Add `--no-verbose` to commit to negate that
setting.

Hmm, this hunk seems to make sure that there can only be two verbosity 
levels, 0 and 1, while before there could be higher levels (which 
produce the same output as verbose = 1).  This change is not mentioned 
in the commit message.  Why is it necessary?

NB: --no-verbose already works without this hunk.

I had no idea, but you're quite right. I suppose that option was just a no-op
before, or could cancel a previous --verbose flag?

Updated diff with that hunk removed follows. I rebuilt the branch and the tests
I added for --no-verbose work as expected, as does actually using the
flag/config with the local build.

Add a new configuration variable commit.verbose to implicitly pass
`--verbose` to `git-commit`. Add `--no-verbose` to commit to negate that
setting.

Another update to also use quotes around the check-for-no-diff script body.

If I don't get any more feedback in the next few hours I'll send another full
version of the patch.
