[PATCH 0/3] Introduce pull.autostash

[PATCH 0/3] Introduce pull.autostash

[Ramkumar Ramachandra]

This series adds a pull.autostash, making 'git pull' a tad bit more
usable.  It is part of my bigger plan to make 'git pull' just DTRT
(via configuration variables) in 90% of the cases.

[1/3] and [2/3] are tiny "while we're here" patches.
[3/3] is the main patch with tests.

Thanks for reading.

[PATCH 1/3] git-pull.sh: prefer invoking "git <command>" over "git-<command>"

[Ramkumar Ramachandra]

14e5d40c (pull: Fix parsing of -X<option>, 2010-01-17) added the lines
containing "git-push" and "git-merge", even though the prevelant style
at the time was to use the unhyphenated "git <command>" form.  Fix
this.

[PATCH 2/3] t5521 (pull-options): use test_commit() where appropriate

[Ramkumar Ramachandra]

test_commit() is a well-defined function in test-lib-functions.sh that
allows you to create commits with a terse syntax.  Prefer using it
over creating commits by hand.

In this test script perhaps it is OK, but I'd prefer people being
careful *not* to use test_commit in tests that involve refs (i.e.
pushing, pulling, ls-remote, for-each-ref, describe...) and paths
(i.e.  ls-files, diff, ...).

There is one good point in the helper: it creates a commit with a
predictable timestamp.

But it does a lot other *bad* things than that single good thing.
It adds a new path, and adds a new tag; neither of which is not
desirable in many circumstances.

A better future direction would be to first make these "frill"
features into options to test_commit helper, fix the users that
depend on these additional tags and stuff to explicitly ask for
them, and then start advocating it for wider use, I think.

Okay.

Yes, test_tick.  I've noticed that several tests call test_tick by
hand before invoking "git commit".

Agreed.  In fact, the commit message is constrained, because of this;
you can't create a commit with a commit message involving spaces,
because that would result in an invalid tag name.

[PATCH 3/3] git-pull.sh: introduce --[no-]autostash and pull.autostash

[Ramkumar Ramachandra]

This new configuration variable executes 'git stash' before attempting
to merge/rebase, and 'git stash pop' after a successful merge/rebase.
It makes it convenient for people to pull with dirty worktrees.

A safety net, after you run "git stash", to validate that the
added "git stash" indeed made the working tree clean, is necessary
below, but there does not seem to be any.

Delaying to run "git stash" as much as possible is fine, but with
the above, can the user tell if something was stashed and she has
to "stash pop" once she is done helping the command to resolve the
conflicts, or she shouldn't run "stash pop" after she is done
(because if nothing is stashed at this point, that "pop" will pop an
unrelated stash)?

What protects the "git stash" from failing and how is its error
handled?

Oops.  I must admit I was in a bit of a hurry with the documentation.
I was eager to send out the series seeing that the tests were passing.

I could easily tell, from the "git pull" output: if conflict, then
stash hasn't been applied.  Otherwise, yes.  Should we print a message
guarded by an advice variable?

Oh, this is my stupidity.  I should've just &&-chained the git stash,
eval $eval, and git stash pop.

You should always "trust but verify" what other commands do at key
points of the operation; and I think this "require-clean-work-tree"
is a key precondition for this mode of operation to work correctly.

Especially because you do not even bother to check the result of
"git stash" before continuing ;-).

The question was about "git stash save".  Depending on the cleanness
of the tree when "git pull" was started, "save" may or may not have
been done.  After resolving a conflicted "git pull" and committing
the result, the user does not have much clue if she needs to pop
anything, does she?  Instead of the usual "resolve the conflicts and
commit the result", she may need to see "resolve the conflicts,
commit the result, *AND* UNSTASH".

If you think it's enough to replicate the codepath that precedes the
actual saving in 'git stash' (which is essentially
require-clean-work-tree), I'm in agreement with you.  I thought you
were implying a wider safety net, that wouldn't even assume the basic
sanity of stash.

Yes, good point.  Will it suffice to print a message?

Er, s/codepath that precedes the actual saving in 'git stash'/codepath
that precedes the actual pulling or merging in 'git pull'/

I'm feeling a little muddled up today; weekends are usually bad.

[PATCH v2 0/3] Introduce pull.autostash

[Ramkumar Ramachandra]

I've been using this patch for some time now, and have to say that
'git pull' is much more useable now.  The feature is turned off by
default so that it doesn't break any existing tests.

[1/3] and [2/3] are simple "while we're there" patches, that are
unchanged from the last round.

[3/3] is actually fine in this round.  I'm embarassed that I sent out
the previous round in such a hurry: there were a lot of things wrong
with it, as Junio's review pointed out.

Ramkumar Ramachandra (3):
  pull: prefer invoking "git <command>" over "git-<command>"
  t5521 (pull-options): use test_commit() where appropriate
  pull: introduce --[no-]autostash and pull.autostash

[PATCH 2/3] t5521 (pull-options): use test_commit() where appropriate

[Ramkumar Ramachandra]

test_commit() is a well-defined function in test-lib-functions.sh that
allows you to create commits with a terse syntax.  Prefer using it
over creating commits by hand.
