sequencer: move check_todo_list_from_file() to rebase-interactive.c
The message contained in `edit_todo_list_advice' (sequencer.c) is
printed after the initial edit of the todo list if it can't be parsed or
if commits were dropped. This is done either in complete_action() for
`rebase -i', or in check_todo_list_from_file() for `rebase -p'.
Since we want to add this check when editing the list, we also want to
use this message from edit_todo_list() (rebase-interactive.c). To this
end, check_todo_list_from_file() is moved to rebase-interactive.c, and
`edit_todo_list_advice' is copied there. In the next commit,
complete_action() will stop using it, and `edit_todo_list_advice' will
be removed from sequencer.c.

rebase -i: also avoid SHA-1 collisions with missingCommitsCheck
When `rebase.missingCommitsCheck` is in effect, we use the backup of the
todo list that was copied just before the user was allowed to edit it.
That backup is, of course, just as susceptible to the hash collision as
the todo list itself: a reworded commit could make a previously
unambiguous short commit ID ambiguous all of a sudden.
So let's not just copy the todo list, but let's instead write out the
backup with expanded commit IDs.

rebase -i: re-fix short SHA-1 collision
In
66ae9a57b88 (t3404: rebase -i: demonstrate short SHA-1 collision,
2013-08-23), we added a test case that demonstrated how it is possible
that a previously unambiguous short commit ID could become ambiguous
*during* a rebase.
In
75c69766554 (rebase -i: fix short SHA-1 collision, 2013-08-23), we
fixed that problem simply by writing out the todo list with expanded
commit IDs (except *right* before letting the user edit the todo list,
in which case we shorten them, but we expand them right after the file
was edited).
However, the bug resurfaced as a side effect of
393adf7a6f6 (sequencer:
directly call pick_commits() from complete_action(), 2019-11-24): as of
this commit, the sequencer no longer re-reads the todo list after
writing it out with expanded commit IDs.
The only redeeming factor is that the todo list is already parsed at
that stage, including all the commits corresponding to the commands,
therefore the sequencer can continue even if the internal todo list has
short commit IDs.
That does not prevent problems, though: the sequencer writes out the
`done` and `git-rebase-todo` files incrementally (i.e. overwriting the
todo list with a version that has _short_ commit IDs), and if a merge
conflict happens, or if an `edit` or a `break` command is encountered, a
subsequent `git rebase --continue` _will_ re-read the todo list, opening
an opportunity for the "short SHA-1 collision" bug again.
To avoid that, let's make sure that we do expand the commit IDs in the
todo list as soon as we have parsed it after letting the user edit it.
Additionally, we improve the 'short SHA-1 collide' test case in t3404 to
test specifically for the case where the rebase is resumed. We also
hard-code the expected colliding short SHA-1s, to document the
expectation (and to make it easier on future readers).
Note that we specifically test that the short commit ID is used in the
`git-rebase-todo.tmp` file: this file is created by the fake editor in
the test script and reflects the state that would have been presented to
the user to edit.

parse_insn_line(): improve error message when parsing failed

While at it, return a negative value from `parse_insn_line()` in case of

mingw: safeguard better against backslashes in file names
In
224c7d70fa1 (mingw: only test index entries for backslashes, not tree
entries, 2019-12-31), we relaxed the check for backslashes in tree
entries to check only index entries.
However, the code change was incorrect: it was added to
`add_index_entry_with_check()`, not to `add_index_entry()`, so under
certain circumstances it was possible to side-step the protection.
Besides, the description of that commit purported that all index entries
would be checked when in fact they were only checked when being added to
the index (there are code paths that do not do that, constructing
"transient" index entries).
In any case, it was pointed out in one insightful review at
https://github.com/git-for-windows/git/pull/2437#issuecomment-
566771835
that it would be a much better idea to teach `verify_path()` to perform
the check for a backslash. This is safer, even if it comes with two
notable drawbacks:
- `verify_path()` cannot say _what_ is wrong with the path, therefore
the user will no longer be told that there was a backslash in the
path, only that the path was invalid.
- The `git apply` command also calls the `verify_path()` function, and
might have been able to handle Windows-style paths (i.e. with
backslashes instead of forward slashes). This will no longer be
possible unless the user (temporarily) sets `core.protectNTFS=false`.
Note that `git add <windows-path>` will _still_ work because
`normalize_path_copy_len()` will convert the backslashes to forward
slashes before hitting the code path that creates an index entry.
The clear advantage is that `verify_path()`'s purpose is to check the
validity of the file name, therefore we naturally tap into all the code
paths that need safeguarding, also implicitly into future code paths.
The benefits of that approach outweigh the downsides, so let's move the
check from `add_index_entry_with_check()` to `verify_path()`.

graph: drop assert() for merge with two collapsing parents
When "git log --graph" shows a merge commit that has two collapsing
lines, like:
| | | | *
| |_|_|/|
|/| | |/
| | |/|
| |/| |
| * | |
* | | |
we trigger an assert():
graph.c:1228: graph_output_collapsing_line: Assertion
`graph->mapping[i - 3] == target' failed.
The assert was introduced by
eaf158f8 ("graph API: Use horizontal
lines for more compact graphs", 2009-04-21), which is quite old.
This assert is trying to say that when we complete a horizontal
line with a single slash, it is because we have reached our target.
It is actually the _second_ collapsing line that hits this assert.
The reason we are in this code path is because we are collapsing
the first line, and in that case we are hitting our target now
that the horizontal line is complete. However, the second line
cannot be a horizontal line, so it will collapse without horizontal
lines. In this case, it is inappropriate to assert that we have
reached our target, as we need to continue for another column
before reaching the target. Dropping the assert is safe here.
The new behavior in
0f0f389f12 (graph: tidy up display of
left-skewed merges, 2019-10-15) caused the behavior change that
made this assertion failure possible. In addition to making the
assert possible, it also changed how multiple edges collapse.
In a larger example, the current code will output a collapse
as follows:
| | | | | | *
| |_|_|_|_|/|\
|/| | | | |/ /
| | | | |/| /
| | | |/| |/
| | |/| |/|
| |/| |/| |
| | |/| | |
| | * | | |
However, the intended collapse should allow multiple horizontal lines
as follows:
| | | | | | *
| |_|_|_|_|/|\
|/| | | | |/ /
| | |_|_|/| /
| |/| | | |/
| | | |_|/|
| | |/| | |
| | * | | |
This behavior is not corrected by this change, but is noted for a later
update.

commit-graph: prefer default size_mult when given zero
In
50f26bd ("fetch: add fetch.writeCommitGraph config setting",
2019-09-02), the fetch builtin added the capability to write a
commit-graph using the "--split" feature. This feature creates
multiple commit-graph files, and those can merge based on a set
of "split options" including a size multiple. The default size
multiple is 2, which intends to provide a log_2 N depth of the
commit-graph chain where N is the number of commits.
However, I noticed during dogfooding that my commit-graph chains
were becoming quite large when left only to builds by 'git fetch'.
It turns out that in split_graph_merge_strategy(), we default the
size_mult variable to 2 except we override it with the context's
split_opts if they exist. In builtin/fetch.c, we create such a
split_opts, but do not populate it with values.
This problem is due to two failures:
1. It is unclear that we can add the flag COMMIT_GRAPH_WRITE_SPLIT
with a NULL split_opts.
2. If we have a non-NULL split_opts, then we override the default
values even if a zero value is given.
Correct both of these issues. First, do not override size_mult when
the options provide a zero value. Second, stop creating a split_opts
in the fetch builtin.

mingw: only test index entries for backslashes, not tree entries
During a clone of a repository that contained a file with a backslash in
its name in the past, as of v2.24.1(2), Git for Windows prints errors
like this:
error: filename in tree entry contains backslash: '\'
The idea is to prevent Git from even trying to write files with
backslashes in their file names: while these characters are valid in
file names on other platforms, on Windows it is interpreted as directory
separator (which would obviously lead to ambiguities, e.g. when there is
a file `a\b` and there is also a file `a/b`).
Arguably, this is the wrong layer for that error: As long as the user
never checks out the files whose names contain backslashes, there should
not be any problem in the first place.
So let's loosen the requirements: we now leave tree entries with
backslashes in their file names alone, but we do require any entries
that are added to the Git index to contain no backslashes on Windows.
Note: just as before, the check is guarded by `core.protectNTFS` (to
allow overriding the check by toggling that config setting), and it
is _only_ performed on Windows, as the backslash is not a directory
separator elsewhere, even when writing to NTFS-formatted volumes.
An alternative approach would be to try to prevent creating files with
backslashes in their file names. However, that comes with its own set of
problems. For example, `git config -f C:\ProgramData\Git\config ...` is
a very valid way to specify a custom config location, and we obviously
do _not_ want to prevent that. Therefore, the approach chosen in this
patch would appear to be better.

merge-recursive: remove unnecessary oid_eq function
Back when merge-recursive was first introduced in commit
6d297f8137
(Status update on merge-recursive in C, 2006-07-08), it created a
sha_eq() function. This function pre-dated the introduction of
hashcmp() to cache.h by about a month, but was switched over to using
hashcmp() as part of commit
9047ebbc22 (Split out merge_recursive() to
merge-recursive.c, 2008-08-12). In commit
b4da9d62f9 (merge-recursive:
convert leaf functions to use struct object_id, 2016-06-24), sha_eq() was
renamed to oid_eq() and its hashcmp() call was switched to oideq().
oid_eq() is basically just a wrapper around oideq() that has some extra
checks to protect against NULL arguments or to allow short-circuiting if
one of the arguments is NULL. I don't know if any caller ever tried to
call with NULL arguments, but certainly none do now which means the
extra checks serve no purpose. (Also, if these checks were genuinely
useful, then they probably should be added to the main oideq() so all
callers could benefit from them.)
Reduce the cognitive overhead of having both oid_eq() and oideq(), by
getting rid of merge-recursive's special oid_eq() wrapper.

sparse-checkout: document interactions with submodules
Using 'git submodule (init|deinit)' a user can select a subset of
submodules to populate. This behaves very similar to the sparse-checkout
feature, but those directories contain their own .git directory
including an object database and ref space. To have the sparse-checkout
file also determine if those files should exist would easily cause
problems. Therefore, keeping these features independent in this way

sparse-checkout: list directories in cone mode
When core.sparseCheckoutCone is enabled, the 'git sparse-checkout set'
command takes a list of directories as input, then creates an ordered
list of sparse-checkout patterns such that those directories are
recursively included and all sibling entries along the parent directories
are also included. Listing the patterns is less user-friendly than the
directories themselves.
In cone mode, and as long as the patterns match the expected cone-mode
pattern types, change the output of 'git sparse-checkout list' to only
show the directories that created the patterns.
With this change, the following piped commands would not change the
working directory:
git sparse-checkout list | git sparse-checkout set --stdin

true, but the sparse-checkout file contains patterns that do not

However, there are legitimate use cases within Git itself to write to

So let's side-step the validation _specifically_ in the case that we

sparse-checkout: improve OS ls compatibility
On FreeBSD, when executed by root ls enables the '-A' option:
-A Include directory entries whose names begin with a dot (`.')
except for . and ... Automatically set for the super-user unless
-I is specified.
As a result the .git directory appeared in the output when run as root.
Simulate no-dotfile ls behaviour using a shell glob.

dir: synchronize treat_leading_path() and read_directory_recursive()
Our optimization to avoid calling into read_directory_recursive() when
all pathspecs have a common leading directory mean that we need to match
the logic that read_directory_recursive() would use if we had just
called it from the root. Since it does more than call treat_path() we
need to copy that same logic.
Alternatively, we could try to change treat_path to return path_recurse
for an untracked directory under the given special circumstances that
this logic checks for, but a simple switch results in many test failures
such as 'git clean -d' not wiping out untracked but empty directories.
To work around that, we'd need the caller of treat_path to check for
path_recurse and sometimes special case it into path_untracked. In
other words, we'd still have extra logic in both places.
Needing to duplicate logic like this means it is guaranteed someone will
eventually need to make further changes and forget to update both
locations. It is tempting to just nuke the leading_directory special
casing to avoid such bugs and simplify the code, but unpack_trees'
verify_clean_subdirectory() also calls read_directory() and does so with
a non-empty leading path, so I'm hesitant to try to restructure further.
Add obnoxious warnings to treat_leading_path() and
read_directory_recursive() to try to warn people of such problems.

dir: fix checks on common prefix directory
Many years ago, the directory traversing logic had an optimization that
would always recurse into any directory that was a common prefix of all
the pathspecs without walking the leading directories to get down to
the desired directory. Thus,
git ls-files -o .git/ # case A
would notice that .git/ was a common prefix of all pathspecs (since
it is the only pathspec listed), and then traverse into it and start
showing unknown files under that directory. Unfortunately, .git/ is not
a directory we should be traversing into, which made this optimization
problematic. This also affected cases like
git ls-files -o --exclude-standard t/ # case B
where t/ was in the .gitignore file and thus isn't interesting and
shouldn't be recursed into. It also affected cases like
git ls-files -o --directory untracked_dir/ # case C
where untracked_dir/ is indeed untracked and thus interesting, but the
--directory flag means we only want to show the directory itself, not
recurse into it and start listing untracked files below it.
The case B class of bugs were noted and fixed in commits
16e2cfa90993
("read_directory(): further split treat_path()", 2010-01-08) and
48ffef966c76 ("ls-files: fix overeager pathspec optimization",
2010-01-08), with the idea being that we first wanted to check whether
the common prefix was interesting. The former patch noted that
treat_path() couldn't be used when checking the common prefix because
treat_path() requires a dir_entry() and we haven't read any directories
at the point we are checking the common prefix. So, that patch split
treat_one_path() out of treat_path(). The latter patch then created a
new treat_leading_path() which duplicated by hand the bits of
treat_path() that couldn't be broken out and then called
treat_one_path() for the remainder. There were three problems with this
approach:
* The duplicated logic in treat_leading_path() accidentally missed the
check for special paths (such as is_dot_or_dotdot and matching
".git"), causing case A types of bugs to continue to be an issue.
* The treat_leading_path() logic assumed we should traverse into
anything where path_treatment was not path_none, i.e. it perpetuated
class C types of bugs.
* It meant we had split logic that needed to kept in sync, running the
risk that people introduced new inconsistencies (such as in commit
be8a84c52669, which we reverted earlier in this series, or in commit
df5bcdf83ae which we'll fix in a subsequent commit)
Fix most these problems by making treat_leading_path() not only loop
over each leading path component, but calling treat_path() directly on
each. To do so, we have to create a synthetic dir_entry, but that only
takes a few lines. Then, pay attention to the path_treatment result we
get from treat_path() and don't treat path_excluded, path_untracked, and
path_recurse all the same as path_recurse.
This leaves one remaining problem, the new inconsistency from commit
df5bcdf83ae. That will be addressed in a subsequent commit.

t4015: improve coverage of function context test
Add a test that includes an actual function line in the test file to
check if context is expanded to include the whole function, and add an
ignored change before function context to check if that one stays hidden
while the originally ignored change within function context is shown.
This differs from the existing test, which is concerned with the case
where there is no function line at all in the file (and we might look
past the beginning of the file).
