Document "git-reset --merge"

The commit log message for the feature made it sound as if this is a saner
version of --mixed, but the use case presented makes it clear that it is a
better variant of --hard when your changes and somebody else's changes are
mixed together.

Perhaps we would want to rewrite the example that shows the use of --hard
not to talk about recovering from a failed merge?

15 years agoAdd 'merge' mode to 'git reset'
Linus Torvalds [Mon, 1 Dec 2008 17:30:31 +0000 (09:30 -0800)]
Add 'merge' mode to 'git reset'

We have always had a nice way to reset a working tree to another state
while carrying our changes around: "git read-tree -u -m". Yes, it fails if
the target tree is different in the paths that are dirty in the working
tree, but this is how we used to switch branches in "git checkout", and it
worked fine.

However, perhaps exactly _because_ we've supported this from very early
on, another low-level command, namely "git reset", never did.

But as time went on, 'git reset' remains as a very common command, while
'git read-tree' is now a very odd and low-level plumbing thing that nobody
sane should ever use, because it only makes sense together with other
operations like either switching branches or just rewriting HEAD.

Which means that we have effectively lost the ability to do something very
common: jump to another point in time without always dropping all our
dirty state.

So add this kind of mode to "git reset", and since it merges your changes
to what you are resetting to, just call it that: "git reset --merge".

I've wanted this for a long time, since I very commonly carry a dirty
tree while working on things. My main 'Makefile' file quite often has the
next version already modified, and sometimes I have local modifications
that I don't want to commit, but I still do pulls and patch applications,
and occasionally want to do "git reset" to undo them - while still keeping
my local modifications.

(Maybe we could eventually change it to something like "if we have a
working tree, default to --merge, otherwise default to --mixed").

NOTE! This new mode is certainly not perfect. There's a few things to look
out for:

 - if the index has unmerged entries, "--merge" will currently simply
   refuse to reset ("you need to resolve your current index first").
   You'll need to use "--hard" or similar in this case.

   This is sad, because normally a unmerged index means that the working
   tree file should have matched the source tree, so the correct action is
   likely to make --merge reset such a path to the target (like --hard),
   regardless of dirty state in-tree or in-index. But that's not how
   read-tree has ever worked, so..

 - "git checkout -m" actually knows how to do a three-way merge, rather
   than refuse to update the working tree. So we do know how to do that,
   and arguably that would be even nicer behavior.

   At the same time it's also arguably true that there is a chance of loss
   of state (ie you cannot get back to the original tree if the three-way
   merge ends up resolving cleanly to no diff at all), so the "refuse to
   do it" is in some respects the safer - but less user-friendly - option.

In other words, I think 'git reset --merge' could become a bit more
friendly, but this is already a big improvement. It allows you to undo a
recent commit without having to throw your current work away.

Yes, yes, with a dirty tree you could always do

git stash
git reset --hard
git stash apply

instead, but isn't "git reset --merge" a nice way to handle one particular
simple case?

Hmm? Maybe I'm the only one that does a lot of work with a dirty tree, and
sure, I can do other things like the "git stash" thing, or using "git
checkout" to actually create a new branch, and then playing games with
branch renaming etc to make it work like this one.

But I suspect others dislike how "git reset" works too. But see the
suggested improvements above.

Note that in both occasions that I've seen this failure, it has not been
due to a missing directory, or bad permissions, but some other, unknown
mkstemp failure mode that did not occur when I ran git again. This code

16 years agobisect: teach "skip" to accept special arguments like "A..B"
Christian Couder [Sun, 23 Nov 2008 21:02:49 +0000 (22:02 +0100)]
bisect: teach "skip" to accept special arguments like "A..B"

The current "git bisect skip" syntax is "git bisect skip [<rev>...]"
so it's already possible to skip a range of revisions using
something like:

$ git bisect skip $(git rev-list A..B)

where A and B are the bounds of the range we want to skip.

This patch teaches "git bisect skip" to accept:

$ git bisect skip A..B

as an abbreviation for the former command.

This is done by checking each argument to see if it contains two
dots one after the other ('..'), and by expending it using
"git rev-list" if that is the case.

Note that this patch will not make "git bisect skip" accept all
that "git rev-list" accepts, as things like "^A B" for exemple
will not work. But things like "A B..C D E F.. ..G H...I" should
work as expected.

mkstemp can fail for many reasons, one of which, ENOENT, can occur if
the directory for the temp file doesn't exist. create_tmpfile tried to
handle this case by always trying to mkdir the directory, even if it

directory name, resulting in the strange error message shown above.

Note that in both occasions that I've seen this failure, it has not been
due to a missing directory, or bad permissions, but some other, unknown
mkstemp failure mode that did not occur when I ran git again. This code

gitk: Show local changes properly when we have a path limit

Since gitk looks for the HEAD commit to attach the fake commits for
local changes to, we can miss out on seeing the fake commits if we
have a path limit and the HEAD commit doesn't alter any of the files
in the path limit.

This fixes it by running

git rev-list -1 $head -- $paths

if we have a path limit, and taking the result of that as the commit
to attach the fake commits to.  This means that we can be attaching
the fake commits to a different commit in each view, so we use a new
$viewmainhead($view) for that.

This also fixes a buglet where updatecommits would only fix up the
fake commits if the HEAD changed since the last call to updatecommits,
whereas it should fix them up if the HEAD has changed since this view
was last created or updated.

Fix index preloading for racy dirty case

In the threaded index preloading case, we must be sure to always use the
CE_MATCH_RACY_IS_DIRTY flag when calling ie_match_stat(), in order to make
sure that we only ever look at the stat() data, and don't try to do
anything fancy.

Because most of git internals are not thread-safe, and must not be called
in parallel.

Otherwise, what happens is that if the timestamps indicate that an entry
_might_ be dirty, we might start actually comparing filesystem data with
the object database. And we mustn't do that, because that would involve
looking up and creating the object structure, and that whole code sequence
with read_sha1_file() where we look up and add objects to the hashes is
definitely not thread-safe.

Nor do we want to add locking, because the whole point of the preload was
to be simple and not affect anything else. With CE_MATCH_RACY_IS_DIRTY, we
get what we wanted, and we'll just leave the hard cases well alone, to be
done later in the much simpler serial case.

not included in the Add dialog to avoid clutter. Also, the
