When "git checkout" removes a path that does not exist in the
commit it is checking out, it wasn't careful enough not to follow
symbolic links, which has been corrected.
* mt/checkout-remove-nofollow:
checkout: don't follow symlinks when removing entries
symlinks: update comment on threaded_check_leading_path()
|

The declarations of entry.c's public functions and structures currently
reside in cache.h. Although not many, they contribute to the size of
cache.h and, when changed, cause the unnecessary recompilation of
modules that don't really use these functions. So let's move them to a
new entry.h header. While at it let's also move a comment related to
checkout_entry() from entry.c to entry.h as it's more useful to describe
the function there.

At 1d718a5108 ("do not overwrite untracked symlinks", 2011-02-20),
symlink.c:check_leading_path() started returning different codes for
FL_ENOENT and FL_SYMLINK. But one of its callers, unlink_entry(), was
not adjusted for this change, so it started to follow symlinks on the
leading path of to-be-removed entries. Fix that and add a regression
test.
Note that since 1d718a5108 check_leading_path() no longer differentiates
the case where it found a symlink in the path's leading components from
the cases where it found a regular file or failed to lstat() the
component. So, a side effect of this current patch is that
unlink_entry() now returns early in all of these three cases. And
because we no longer try to unlink such paths, we also don't get the
warning from remove_or_warn().
For the regular file and symlink cases, it's questionable whether the
warning was useful in the first place: unlink_entry() removes tracked
paths that should no longer be present in the state we are checking out
to. If the path had its leading dir replaced by another file, it means
that the basename already doesn't exist, so there is no need for a
warning. Sure, we are leaving a regular file or symlink behind at the
path's dirname, but this file is either untracked now (so again, no
need to warn), or it will be replaced by a tracked file during the next
phase of this checkout operation.
As for failing to lstat() one of the leading components, the basename
might still exist only we cannot unlink it (e.g. due to the lack of the
required permissions). Since the user expect it to be removed
(especially with checkout's --no-overlay option), add back the warning
in this more relevant case.

In 56c6910028a (fsmonitor: change last update timestamp on the
index_state to opaque token, 2020-01-07), we forgot to adjust the part
of `unpack_trees()` that copies the FSMonitor "last-update" information
that we copy from the source index to the result index since 679f2f9fdd2
(unpack-trees: skip stat on fsmonitor-valid files, 2019-11-20).
Since the "last-update" information is no longer a 64-bit number, but a
free-form string that has been allocated, we need to duplicate it rather
than just copying it.
This is important because there _are_ cases when `unpack_trees()` will
perform a oneway merge that implicitly calls `refresh_fsmonitor()`
(which will allocate that "last-update" token). This happens _after_
that token was copied into the result index. However, we _then_ call
`check_updates()` on that index, which will _also_ call
`refresh_fsmonitor()`, accessing the "last-update" string, which by now
would be released already.
In the instance that lead to this patch, this caused a segmentation
fault during a lengthy, complicated rebase involving the todo command
`reset` that (crucially) had to updated many files. Unfortunately, it
seems very hard to trigger that crash, therefore this patch is not
accompanied by a regression test.

Stash entries can be made with untracked files via
`git stash push --include-untracked`. However, because the untracked
files are stored in the third parent of the stash entry and not the
stash entry itself, running `git stash show` does not include the
untracked files as part of the diff.
With --include-untracked, untracked paths, which are recorded in the
third-parent if it exists, are shown in addition to the paths that have
modifications between the stash base and the working tree in the stash.
It is possible to manually craft a malformed stash entry where duplicate
untracked files in the stash entry will mask tracked files. We detect
and error out in that case via a custom unpack_trees() callback:
stash_worktree_untracked_merge().
Also, teach stash the --only-untracked option which only shows the
untracked files of a stash entry. This is similar to `git show stash^3`
but it is nice to provide a convenient abstraction for it so that users
do not have to think about the underlying implementation.

A future feature will want to load the sparse-checkout patterns into a
pattern_list, but the current mechanism to do so is a bit complicated.
This is made difficult due to needing to find the sparse-checkout file
in different ways throughout the codebase.
The logic implemented in the new get_sparse_checkout_patterns() was
duplicated in populate_from_existing_patterns() in unpack-trees.c. Use
the new method instead, keeping the logic around handling the struct
unpack_trees_options.
The callers to get_sparse_checkout_filename() in
builtin/sparse-checkout.c manipulate the sparse-checkout file directly,
so it is not appropriate to replace logic in that file with
get_sparse_checkout_patterns().

Make the method safer by allocating a cache_tree member for the given
index_state if it is not already present. This is preferrable to a
BUG() statement or returning with an error because future callers will
want to populate an empty cache-tree using this method.
Callers can also remove their conditional allocations of cache_tree.
Also drop local variables that can be found directly from the 'istate'

We eventually want to drop the argv_array name and just use strvec
consistently. There's no particular reason we have to do it all at once,
or care about interactions between converted and unconverted bits.
Because of our preprocessor compat layer, the names are interchangeable
to the compiler (so even a definition and declaration using different
names is OK).
This patch converts all of the remaining files, as the resulting diff is
reasonably sized.
The conversion was done purely mechanically with:
git ls-files '*.c' '*.h' |
xargs perl -i -pe '
s/ARGV_ARRAY/STRVEC/g;
s/argv_array/strvec/g;

commit b0a5a12a60 ("unpack-trees: allow check_updates() to work on a

work on o->result much like check_updates() had been. Update it to also
accept an index parameter and have check_updates() pass that parameter
along so that both are working on the same index.

The loop in warn_conflicted_path() that checks for the count of

Remove the error condition when updating the sparse-checkout leaves
an empty working directory.
This behavior was added in 9e1afb167 (sparse checkout: inhibit empty
worktree, 2009-08-20). The comment was added in a7bc906f2 (Add
explanation why we do not allow to sparse checkout to empty working
tree, 2011-09-22) in response to a "dubious" comment in 84563a624
(unpack-trees.c: cosmetic fix, 2010-12-22).
With the recent "cone mode" and "git sparse-checkout init [--cone]"
command, it is common to set a reasonable sparse-checkout pattern
set of
/*
!/*/
which matches only files at root. If the repository has no such files,
then their "git sparse-checkout init" command will fail.
Now that we expect this to be a common pattern, we should not have the
commands fail on an empty working directory. If it is a confusing
result, then the user can recover with "git sparse-checkout disable"
or "git sparse-checkout set". This is especially simple when using cone
mode.

Setting and clearing of the SKIP_WORKTREE bit is not only done when
users run 'sparse-checkout'; other commands such as 'checkout' also run
through unpack_trees() which has logic for handling this special bit.
As such, we need to consider how they handle special cases. A couple
comparison points should help explain the rationale for changing how
unpack_trees() handles these bits:
Ignoring sparse checkouts for a moment, if you are switching
branches and have dirty changes, it is only considered an error that
will prevent the branch switching from being successful if the dirty
file happens to be one of the paths with different contents.
SKIP_WORKTREE has always been considered advisory; for example, if
rebase or merge need or even want to materialize a path as part of
their work, they have always been allowed to do so regardless of the
SKIP_WORKTREE setting. This has been used for unmerged paths, but
it was often used for paths it wasn't needed just because it made
the code simpler. It was a best-effort consideration, and when it
materialized paths contrary to the SKIP_WORKTREE setting, it was
never required to even print a warning message.
In the past if you trying to run e.g. 'git checkout' and:
1) you had a path that was materialized and had some dirty changes
2) the path was listed in $GITDIR/info/sparse-checkout
3) this path did not different between the current and target branches
then despite the comparison points above, the inability to set
SKIP_WORKTREE was treated as a *hard* error that would abort the
checkout operation. This is completely inconsistent with how
SKIP_WORKTREE is handled elsewhere, and rather annoying for users as
leaving the paths materialized in the working copy (with a simple
warning) should present no problem at all.
Downgrade any errors from inability to toggle the SKIP_WORKTREE bit to a
warning and allow the operations to continue.

Previously, the only way to update the SKIP_WORKTREE bits for various
paths was invoking `git read-tree -mu HEAD` or calling the same code
that this codepath invoked. This however had a number of problems if
the index or working directory were not clean. First, let's consider
the case:
Flipping SKIP_WORKTREE -> !SKIP_WORKTREE (materializing files)
If the working tree was clean this was fine, but if there were files or
directories or symlinks or whatever already present at the given path
then the operation would abort with an error. Let's label this case
for later discussion:
A) There is an untracked path in the way
Now let's consider the opposite case:
Flipping !SKIP_WORKTREE -> SKIP_WORKTREE (removing files)
If the index and working tree was clean this was fine, but if there were
any unclean paths we would run into problems. There are three different
cases to consider:
B) The path is unmerged
C) The path has unstaged changes
D) The path has staged changes (differs from HEAD)
If any path fell into case B or C, then the whole operation would be
aborted with an error. With sparse-checkout, the whole operation would
be aborted for case D as well, but for its predecessor of using `git
read-tree -mu HEAD` directly, any paths that fell into case D would be
removed from the working copy and the index entry for that path would be
reset to match HEAD -- which looks and feels like data loss to users
(only a few are even aware to ask whether it can be recovered, and even
then it requires walking through loose objects trying to match up the
right ones).
Refusing to remove files that have unsaved user changes is good, but
refusing to work on any other paths is very problematic for users. If
the user is in the middle of a rebase or has made modifications to files
that bring in more dependencies, then for their build to work they need
to update the sparse paths. This logic has been preventing them from
doing so. Sometimes in response, the user will stage the files and
re-try, to no avail with sparse-checkout or to the horror of losing
their changes if they are using its predecessor of `git read-tree -mu
HEAD`.
Add a new update_sparsity() function which will not error out in any of
these cases but behaves as follows for the special cases:
A) Leave the file in the working copy alone, clear the SKIP_WORKTREE
bit, and print a warning (thus leaving the path in a state where
status will report the file as modified, which seems logical).
B) Do NOT mark this path as SKIP_WORKTREE, and leave it as unmerged.
C) Do NOT mark this path as SKIP_WORKTREE and print a warning about
the dirty path.
D) Mark the path as SKIP_WORKTREE, but do not revert the version
stored in the index to match HEAD; leave the contents alone.
I tried a different behavior for A (leave the SKIP_WORKTREE bit set),
but found it very surprising and counter-intuitive (e.g. the user sees
it is present along with all the other files in that directory, tries to
stage it, but git add ignores it since the SKIP_WORKTREE bit is set). A
& C seem like optimal behavior to me. B may be as well, though I wonder
if printing a warning would be an improvement. Some might be slightly
surprised by D at first, but given that it does the right thing with
`git commit` and even `git commit -a` (`git add` ignores entries that
are marked SKIP_WORKTREE and thus doesn't delete them, and `commit -a`
is similar), it seems logical to me.

If a path is dirty, removing from the working tree risks losing data.
As such, we want to make sure any such path is not marked with
SKIP_WORKTREE. While the current callers of this code detect this case
and re-populate with a previous set of sparsity patterns, we want to
allow some paths to be marked with SKIP_WORKTREE while others are left
unmarked without it being considered an error. The reason this
shouldn't be considered an error is that SKIP_WORKTREE has always been
an advisory-only setting; merge and rebase for example were free to
materialize paths and clear the SKIP_WORKTREE bit in order to accomplish
their work even though they kept the SKIP_WORKTREE bit set for other
paths. Leaving dirty working files in the working tree is thus a
natural extension of what we have already been doing.

commit e091228e17 ("sparse-checkout: update working directory
in-process", 2019-11-21) allowed passing a pre-defined set of patterns
to unpack_trees(). However, if o->pl was NULL, it would still read the
existing patterns and use those. If those patterns were read into a
data structure that was allocated, naturally they needed to be free'd.
However, despite the same function being responsible for knowing about
both the allocation and the free'ing, the logic for tracking whether to
free the pattern_list was hoisted to an outer function with an
additional flag in unpack_trees_options. Put the logic back in the
relevant function and discard the now unnecessary flag.

verify_absent_sparse() was introduced in commit 08402b0409
("merge-recursive: distinguish "removed" and "overwritten" messages",
2010-08-11), and has always had exactly one caller which always passes
error_type == ERROR_WOULD_LOSE_UNTRACKED_OVERWRITTEN. This function
then checks whether error_type is this value, and if so, sets it instead
to ERROR_WOULD_LOSE_ORPHANED_OVERWRITTEN. It has been nearly a decade
and no other caller has been created, and no other value has ever been
passed, so just pass the expected value to begin with.

commit 08402b0409 ("merge-recursive: distinguish "removed" and
"overwritten" messages", 2010-08-11) split
ERROR_WOULD_LOSE_UNTRACKED
into both
ERROR_WOULD_LOSE_UNTRACKED_OVERWRITTEN
ERROR_WOULD_LOSE_UNTRACKED_REMOVED
and also split
ERROR_WOULD_LOSE_ORPHANED
into both
ERROR_WOULD_LOSE_ORPHANED_OVERWRITTEN
ERROR_WOULD_LOSE_ORPHANED_REMOVED
However, despite the split only three of these four types were used.
ERROR_WOULD_LOSE_ORPHANED_REMOVED was not put into use when it was
introduced and nothing else has used it in the intervening decade
either. Remove it.
