I would actually suggest doing this the other way around. --autostash
option, followed by configuration if needed.
I actually have this slight suspicion that rebase.autostash and
pull.autostash may want to be separate variables. Attempting to
rebase locally when your working tree is in half-baked state is bad
enough but may be warranted in some workflows, but doing so when
integrating with other people's work is a practice in a different
league. It would be quite sensible for somebody to want to allow the
former (i.e. allows autostash with rebase.autostash=true for local
rebase) while retaining the safety of the latter (i.e. stop pulling
with pull.autostash=false).

The only (slight) issue is that rr/rebase-autostash will become hard to find once Junio cleans up feature branches that have graduated. Since that branch has graduated to master, it would be clearer to refer to commit 5879477 (rebase: implement --[no-]autostash and rebase.autostash, 2013-05-12). Is something like this clearer? "git pull" currently cannot be used with the "autostash" feature added to "git rebase" by commit 5879477 (rebase: implement --[no-]autostash and rebase.autostash, 2013-05-12) because it unconditionally calls requre_clean_worktree early on, which results in: # dirty worktree or index $ git pull Cannot pull with rebase: Your index contains uncommitted changes. Please commit or stash them. Remove this restriction by skipping the call to require_clean_worktree if the "rebase.autostash" configuration variable is set. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Having said all that, I see now that 2/2 in this series is really
unrelated to this commit and is not the rest of the autostash
implementation, so I am more confused than before. Was the rest of
'autostash' already implemented in some other series? I guess that's
what you meant by "rr/rebase-autostash" which is NOT "this commit"
after all. I am sorry for my confusion, though a clearer commit
message would have helped me in the first place.

This commit message does not tell me what this commit does. It mostly
describes the current situation. Then it refers to something called
"rr/rebase-autostash" which will lose meaning in the future when this
commit is no longer current on the list. A better way to refer to
this commit is to say "this commit". However, even this is not the
norm for this project. The norm here is to avoid such noise by
speaking in the imperative mood. That is, do not tell me what this
commit does; instead, tell the code what to do. See
Documentation/SubmittingPatches:
Describe your changes in imperative mood, e.g. "make xyzzy do frotz"
instead of "[This patch] makes xyzzy do frotz" or "[I] changed xyzzy
to do frotz", as if you are giving orders to the codebase to change
its behaviour. Try to make sure your explanation can be understood
without external resources. Instead of giving a URL to a mailing list
archive, summarize the relevant points of the discussion.

This commit does not seem useful on its own. All it does is prevent
the safety check for a clean work tree when the autostash flag is set.
I understand that this is necessary for the rest of the change to be
useful, but I do not see any reason for it to be split into two
commits like this. I think it would be more understandable if this
were squashed together with the rest of the change, both now for
reviews and in the future when someone tries to understand this change
in retrospect.
In particular, the commit message suggests that this commit will
perform the autostash if this variable is set, but it does not do that
yet. I think if you squash these two together it will be more concise
and understandable.
Thanks,
Phil

Trivial, indeed!
It would be nice to have an --autostash command-line option too, and the
error message in "require_clean_work_tree" could suggest using it. That
would make the feature easily discoverable.
Perhaps this patch could mention "pull --rebase" in the doc, like (config.txt)
- ends. This means that you can run rebase on a dirty worktree.
