dir: treat_leading_path() and read_directory_recursive(), round 2
I was going to title this "dir: more synchronizing of
treat_leading_path() and read_directory_recursive()", a nod to commit
777b42034764 ("dir: synchronize treat_leading_path() and
read_directory_recursive()", 2019-12-19), but the title was too long.
Anyway, first the backstory...
fill_directory() has always had a slightly error-prone interface: it
returns a subset of paths which *might* match the specified pathspec; it
was intended to prune away some paths which didn't match the specified
pathspec and keep at least all the ones that did match it. Given this
interface, callers were responsible to post-process the results and
check whether each actually matched the pathspec.
builtin/clean.c did this. It would first prune out duplicates (e.g. if
"dir" was returned as well as all files under "dir/", then it would
simplify this to just "dir"), and after pruning duplicates it would
compare the remaining paths to the specified pathspec(s). This
post-processing itself could run into problems, though, as noted in
commit
404ebceda01c ("dir: also check directories for matching
pathspecs", 2019-09-17):
For the case of git-clean and a set of pathspecs of "dir/file" and
"more", this caused a problem because we'd end up with dir entries
for both of
"dir"
"dir/file"
Then correct_untracked_entries() would try to helpfully prune
duplicates for us by removing "dir/file" since it's under "dir",
leaving us with
"dir"
Since the original pathspec only had "dir/file", the only entry left
doesn't match and leaves nothing to be removed. (Note that if only
one pathspec was specified, e.g. only "dir/file", then the
common_prefix_len optimizations in fill_directory would cause us to
bypass this problem, making it appear in simple tests that we could
correctly remove manually specified pathspecs.)
That commit fixed the issue -- when multiple pathspecs were specified --
by making sure fill_directory() wouldn't return both "dir" and
"dir/file" outside the common_prefix_len optimization path. This is
where it starts to get fun.
In commit
b9670c1f5e6b ("dir: fix checks on common prefix directory",
2019-12-19), we noticed that the common_prefix_len wasn't doing
appropriate checks and letting all kinds of stuff through, resulting in
recursing into .git/ directories and other craziness. So it started
locking down and doing checks on pathnames within that code path. That
continued with commit
777b42034764 ("dir: synchronize
treat_leading_path() and read_directory_recursive()", 2019-12-19), which
noted the following:
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.
...and then it more forcefully addressed the issue with this wonderfully
ironic statement:
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.
You would think that with such a strongly worded description, that its
author would have actually ensured that the logic in
treat_leading_path() and read_directory_recursive() did actually match
and that *everything* that was needed had at least been copied over at
the time that this paragraph was written. But you'd be wrong, I messed
it up by missing part of the logic.
Copy the missing bits to fix the new final test in t7300.

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()`.

unpack-trees: correctly compute result count
The clear_ce_flags_dir() method processes the cache entries within
a common directory. The returned int is the number of cache entries
processed by that directory. When using the sparse-checkout feature
in cone mode, we can skip the pattern matching for entries in the
directories that are entirely included or entirely excluded.
eb42feca (unpack-trees: hash less in cone mode, 2019-11-21)
introduced this performance feature. The old mechanism relied on
the counts returned by calling clear_ce_flags_1(), but the new
mechanism calculated the number of rows by subtracting "cache_end"
from "cache" to find the size of the range. However, the equation
is wrong because it divides by sizeof(struct cache_entry *). This
is not how pointer arithmetic works!
A coverity build of Git for Windows in preparation for the 2.25.0
release found this issue with the warning, "Pointer differences,
such as cache_end - cache, are automatically scaled down by the
size (8 bytes) of the pointed-to type (struct cache_entry *).
Most likely, the division by sizeof(struct cache_entry *) is
extraneous and should be eliminated." This warning is correct.
This leaves us with the question "how did this even work?" The
problem that occurs with this incorrect pointer arithmetic is
a performance-only bug, and a very slight one at that. Since
the entry count returned by clear_ce_flags_dir() is reduced by
a factor of 8, the loop in clear_ce_flags_1() will re-process
entries from those directories.
By inserting global counters into unpack-tree.c and tracing
them with trace2_data_intmax() (in a private change, for
testing), I was able to see count how many times the loop inside
clear_ce_flags_1() processed an entry and how many times
clear_ce_flags_dir() was called. Each of these are reduced by at
least a factor of 8 with the current change. A factor larger
than 8 happens when multiple levels of directories are repeated.
Specifically, in the Linux kernel repo, the command
git sparse-checkout set LICENSES
restricts the working directory to only the files at root and
in the LICENSES directory. Here are the measured counts:
clear_ce_flags_1 loop blocks:
Before: 11,520
After: 1,621
clear_ce_flags_dir calls:
Before: 7,048
After: 606
While these are dramatic counts, the time spent in
clear_ce_flags_1() is under one millisecond in each case, so
the improvement is not measurable as an end-to-end time.

lines, like:
| | | | *

| |/| |
| * | |

`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:
| | | | | | *
| |_|_|_|_|/|\
|/| | | | |/ /
| | |_|_|/| /
| |/| | | |/
| | | |_|/|
| | |/| | |

transport: don't flush when disconnecting stateless-rpc helper
Since
ba227857d2 (Reduce the number of connects when fetching,

packet. This cleanly tells the other side that we're done, and avoids
the other side complaining "the remote end hung up unexpectedly" (though
we'd only see that for transports that pass along the server stderr,
like ssh or local-host).
But when we've initiated a v2 stateless-connect session over a transport
helper, there's no point in sending this flush packet. Each operation
we've performed is self-contained, and the other side is fine with us
hanging up between operations.
But much worse, by sending the flush packet we may cause the helper to
issue an entirely new request _just_ to send the flush packet. So we can
incur an extra network request just to say "by the way, we have nothing
more to send".
Let's drop this extra flush packet. As the test shows, this reduces the

restore: invalidate cache-tree when removing entries with --staged
When "git restore --staged <path>" removes a path that's in the index,
it marks the entry with CE_REMOVE, but we don't do anything to
invalidate the cache-tree. In the non-staged case, we end up in
checkout_worktree(), which calls remove_marked_cache_entries(). That
actually drops the entries from the index, as well as invalidating the
cache-tree and untracked-cache.
But with --staged, we never call checkout_worktree(), and the CE_REMOVE
entries remain. Interestingly, they are dropped when we write out the
index, but that means the resulting index is inconsistent: its
cache-tree will not match the actual entries, and running "git commit"
immediately after will create the wrong tree.
We can solve this by calling remove_marked_cache_entries() ourselves
before writing out the index. Note that we can't just hoist it out of
checkout_worktree(); that function needs to iterate over the CE_REMOVE
entries (to drop their matching worktree files) before removing them.
One curiosity about the test: without this patch, it actually triggers a
BUG() when running git-restore:
BUG: cache-tree.c:810: new1 with flags 0x4420000 should not be in cache-tree
But in the original problem report, which used a similar recipe,
git-restore actually creates the bogus index (and the commit is created
with the wrong tree). I'm not sure why the test here behaves differently
than my out-of-suite reproduction, but what's here should catch either
symptom (and the fix corrects both cases).

then check whether it's NULL. However, this is undefined behavior if
the pointer is non-NULL, since the C standard no longer permits us to
use a valid pointer after freeing it.
The only case in which the C standard would permit this to be defined
behavior is if r were NULL, since it states that in such a case "no
action occurs" as a result of calling free.
It's easy to suggest that this is not likely to be a problem, but we
know that GCC does aggressively exploit the fact that undefined
behavior can never occur to optimize and rewrite code, even when that's
contrary to the expectations of the programmer. It is, in fact, very
common for it to omit NULL pointer checks, just as we have here.
Since it's easy to fix, let's do so, and avoid a potential headache in
the future.

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.

sha1-file: remove OBJECT_INFO_SKIP_CACHED
In a partial clone, if a user provides the hash of the empty tree ("git
mktree </dev/null" - for SHA-1, this is 4b825d...) to a command which
requires that that object be parsed, for example:
git diff-tree 4b825d <a non-empty tree>
then Git will lazily fetch the empty tree, unnecessarily, because
parsing of that object invokes repo_has_object_file(), which does not
special-case the empty tree.
Instead, teach repo_has_object_file() to consult find_cached_object()
(which handles the empty tree), thus bringing it in line with the rest
of the object-store-accessing functions. A cost is that
repo_has_object_file() will now need to oideq upon each invocation, but
that is trivial compared to the filesystem lookup or the pack index
search required anyway. (And if find_cached_object() needs to do more
because of previous invocations to pretend_object_file(), all the more
reason to be consistent in whether we present cached objects.)
As a historical note, the function now known as repo_read_object_file()
was taught the empty tree in
346245a1bb ("hard-code the empty tree
object", 2008-02-13), and the function now known as oid_object_info()
was taught the empty tree in
c4d9986f5f ("sha1_object_info: examine
cached_object store too", 2011-02-07). repo_has_object_file() was never
updated, perhaps due to oversight. The flag OBJECT_INFO_SKIP_CACHED,
introduced later in
dfdd4afcf9 ("sha1_file: teach
sha1_object_info_extended more flags", 2017-06-26) and used in
e83e71c5e1 ("sha1_file: refactor has_sha1_file_with_flags", 2017-06-26),
was introduced to preserve this difference in empty-tree handling, but
now it can be removed.

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.

mingw: refuse paths containing reserved names
There are a couple of reserved names that cannot be file names on
Windows, such as `AUX`, `NUL`, etc. For an almost complete list, see
https://docs.microsoft.com/en-us/windows/win32/fileio/naming-a-file
If one would try to create a directory named `NUL`, it would actually
"succeed", i.e. the call would return success, but nothing would be
created.
Worse, even adding a file extension to the reserved name does not make
it a valid file name. To understand the rationale behind that behavior,
see https://devblogs.microsoft.com/oldnewthing/

mingw: short-circuit the conversion of `/dev/null` to UTF-16
In the next commit, we want to disallow accessing any path that contains
any segment that is equivalent to `NUL`. In particular, we want to
disallow accessing `NUL` (e.g. to prevent any repository from being
checked out that contains a file called `NUL`, as that is not a valid
file name on Windows).
However, there are legitimate use cases within Git itself to write to
the Null device. As Git is really a Linux project, it does not abstract
that idea, though, but instead uses `/dev/null` to describe this
intention.
So let's side-step the validation _specifically_ in the case that we
want to write to (or read from) `/dev/null`, via a dedicated short-cut
in the code that skips the call to `validate_win32_path()`.

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.
