git-rebase--interactive.sh: rework skip_unnecessary_picks

Commit cd035b1c introduced the exec command to interactive rebase.  In
doing so, it modified the way that skip_unnecessary_picks iterates through
the list of rebase commands so that it avoided collapsing multiple spaces
into a single space.  This is necessary for example if the argument to the
exec command contains a path with multiple spaces in it.

The way it did this was by reading each line of rebase commands into a
single variable, and then breaking the individual components out using
echo, sed, and cut.  It used the individual broken-out components for
decision making, and was still able to write the original line to the
output file from the variable it had saved it in.  But, since we only
really need to look at anything other than the first element of the line
when a 'pick' command is encountered, and even that is only necessary when
we are still searching for "unnecessary" picks, and since newer rebase
commands like 'exec' may not even require a sha1 field, let's make our read
statement parse its input into a "command" variable, and a "rest" variable,
and then only break out the sha1 from $rest, and call git-rev-parse, when
absolutely necessary.

I think this future proofs this subroutine, avoids calling git-rev-parse
unnecessarily, and possibly with bogus arguments, and still accomplishes
the goal of not mangling the $rest of the rebase command.

diff --follow: do call diffcore_std() as necessary

Usually, diff frontends populate the output queue with filepairs without
any rename information and call diffcore_std() to sort the renames out.
When --follow is in effect, however, diff-tree family of frontend has a
hack that looks like this:

    diff-tree frontend
    -> diff_tree_sha1()
       . populate diff_queued_diff
       . if --follow is in effect and there is only one change that
         creates the target path, then
       -> try_to_follow_renames()
  -> diff_tree_sha1() with no pathspec but with -C
  -> diffcore_std() to find renames
  . if rename is found, tweak diff_queued_diff and put a
    single filepair that records the found rename there
    -> diffcore_std()
       . tweak elements on diff_queued_diff by
       - rename detection
       - path ordering
       - pickaxe filtering

We need to skip parts of the second call to diffcore_std() that is related
to rename detection, and do so only when try_to_follow_renames() did find
a rename.  Earlier 1da6175 (Make diffcore_std only can run once before a
diff_flush, 2010-05-06) tried to deal with this issue incorrectly; it
unconditionally disabled any second call to diffcore_std().

This hopefully fixes the breakage.

diff --follow: do not waste cycles while recursing

The "--follow" logic is called from diff_tree_sha1() function, but the
input trees to diff_tree_sha1() are not necessarily the top-level trees
(compare_tree_entry() calls it while it recursively descends into
subtrees).  When a newly created path lives in somewhere deep in the
source hierarchy, e.g. "platform/", but the rename source is in a totally
different place in the destination hierarchy, e.g. "lang-api/src/com/...",
running "try_to_find_renames()" while base is set to "platform/" is a
wasted call.

We only need to run the rename following at the very top level.

13 years agopull --rebase: Avoid spurious conflicts and reapplying unnecessary patches
Elijah Newren [Fri, 13 Aug 2010 01:50:50 +0000 (19:50 -0600)] 
pull --rebase: Avoid spurious conflicts and reapplying unnecessary patches

Prior to c85c792 (pull --rebase: be cleverer with rebased upstream
branches, 2008-01-26), pull --rebase would run

  git rebase $merge_head

which resulted in a call to

  git format-patch ... --ignore-if-in-upstream $merge_head..$cur_branch

This resulted in patches from $merge_head..$cur_branch being applied, as
long as they did not already exist in $cur_branch..$merge_head.

Unfortunately, when upstream is rebased, $merge_head..$cur_branch also
refers to "old" commits that have already been rebased upstream, meaning
that many patches that were already fixed upstream would be reapplied.
This could result in many spurious conflicts, as well as reintroduce
patches that were intentionally dropped upstream.

So the algorithm was changed in c85c792 (pull --rebase: be cleverer with
rebased upstream branches, 2008-01-26) and d44e712 (pull: support rebased
upstream + fetch + pull --rebase, 2009-07-19).  Defining $old_remote_ref to
be the most recent entry in the reflog for @{upstream} that is an ancestor
of $cur_branch, pull --rebase was changed to run

  git rebase --onto $merge_head $old_remote_ref

which results in a call to

  git format-patch ... --ignore-if-in-upstream $old_remote_ref..$cur_branch

The whole point of this change was to reduce the number of commits being
reapplied, by avoiding commits that upstream already has or had.

In the rebased upstream case, this change achieved that purpose.  It is
worth noting, though, that since $old_remote_ref is always an ancestor of
$cur_branch (by its definition), format-patch will not know what upstream
is and thus will not be able to determine if any patches are already
upstream; they will all be reapplied.

In the non-rebased upstream case, this new form is usually the same as the
original code but in some cases $old_remote_ref can be an ancestor of

   $(git merge-base $merge_head $cur_branch)

meaning that instead of avoiding reapplying commits that upstream already
has, it actually includes more such commits.  Combined with the fact that
format-patch can no longer detect commits that are already upstream (since
it is no longer told what upstream is), results in lots of confusion for
users (e.g. "git is giving me lots of conflicts in stuff I didn't even
change since my last push.")

Cases where additional commits could be reapplied include forking from a
commit other than the tracking branch, or amending/rebasing after pushing.
Cases where the inability to detect upstreamed commits cause problems
include independent discovery of a fix and having your patches get
upstreamed by some alternative route (e.g. pulling your changes to a third
machine, pushing from there, and then going back to your original machine
and trying to pull --rebase).

Fix the non-rebased upstream case by ignoring $old_remote_ref whenever it
is contained in $(git merge-base $merge_head $cur_branch).  This should
have no affect on the rebased upstream case.

diff: strip extra "/" when stripping prefix

There are two ways a user might want to use "diff --relative":

  1. For a file in a directory, like "subdir/file", the user
     can use "--relative=subdir/" to strip the directory.

  2. To strip part of a filename, like "foo-10", they can
     use "--relative=foo-".

We currently handle both of those situations. However, if the user passes

unpack-trees: do not check for conflict entries too early

The idea of sparse checkout is conflict entries should always stay
in worktree, regardless $GIT_DIR/info/sparse-checkout. Therefore,
ce_stage(ce) usually means no CE_SKIP_WORKTREE. This is true when all
entries have been merged into the index, and identical staged entries
collapsed.

However, will_have_skip_worktree() since f1f523e (unpack-trees():
ignore worktree check outside checkout area) is also used earlier in
verify_* functions, where entries have not been merged to index yet
and ce_stage() is not zero. Checking ce_stage() then may provoke
unnecessary verification on entries outside checkout area and error
out.

This fixes part of test case "read-tree adds to worktree, dirty case".
The error

13 years agounpack-trees: let read-tree -u remove index entries outside sparse area

unpack-trees: let read-tree -u remove index entries outside sparse area

To avoid touching the worktree outside a sparse checkout,
when the update flag is enabled unpack_trees() clears the
CE_UPDATE and CE_REMOVE flags on entries that do not match the
sparse pattern before actually committing any updates to the
index file or worktree.

The effect on the index was unintentional; sparse checkout was
never meant to prevent index updates outside the area checked
out.  And the result is very confusing: for example, after a
failed merge, currently "git reset --hard" does not reset the
state completely but an additional "git reset --mixed" will.

So stop clearing the CE_REMOVE flag.  Instead, maintain a
CE_WT_REMOVE flag to separately track whether a particular
file removal should apply to the worktree in addition to the
index or not.

The CE_WT_REMOVE flag is used already to mark files that
should be removed because of a narrowing checkout area.  That
usage will still apply; do not clear the CE_WT_REMOVE flag
in that case (detectable because the CE_REMOVE flag is not
set).

This bug masked some other bugs illustrated by the test
suite, which will be addressed by later patches.

Nguyễn Thái Ngọc Duy [Sat, 31 Jul 2010 06:14:26 +0000 (13:14 +0700)] 
unpack-trees: only clear CE_UPDATE|CE_REMOVE when skip-worktree is always set

The purpose of this clearing is, as explained in comment, because
verify_*() may set those bits before apply_sparse_checkout() is
called. By that time, it's not clear whether an entry will stay in
checkout area or out. After $GIT_DIR/info/sparse-checkout is applied,
we know what entries will be in finally. It's time to clean unwanted
bits.

That works perfectly when checkout area remains unchanged. When
checkout area changes, apply_sparse_checkout() may set CE_UPDATE
or CE_WT_REMOVE to widen/narrow checkout area. Doing the clearing
after apply_sparse_checkout() may clear those widening/narrowing
bits unexpectedly.

So, only do that on entries that are not affected by checkout area
changes (i.e. skip-worktree bit does not change after
apply_sparse_checkout).

This code does not actually fix anything though, just
future-proof. The removed code and the narrow/widen code inside
apply_sparse_checkout are currently independent (narrow code never
sets CE_REMOVE, widen code sets CE_UPDATE, but ce_skip_worktree()
would be false).
