4 years agomingw: safeguard better against backslashes in file names
Johannes Schindelin via GitGitGadget [Thu, 9 Jan 2020 13:30:34 +0000 (13:30 +0000)] 
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()`.

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.

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
number of POSTs required for a v2 ls-remote over http from 2 to 1.

unpack-trees: watch for out-of-range index position

It's possible in a case where the index file contains a tree extension
but no blobs within that tree exist for index_pos_by_traverse_info() to
segfault. If the name_entry passed into index_pos_by_traverse_info() has
no blobs inside, AND is alphabetically later than all blobs currently in
the index file, index_pos_by_traverse_info() will segfault. For example,
an index file which looks something like this:

  aaa#0
  bbb/aaa#0
  [Extensions]
  TREE: zzz

In this example, 'index_name_pos(..., "zzz/", ...)' will return '-4',
indicating that "zzz/" could be inserted at position 3. However, when
the checks which ensure that the insertion position of "zzz/" look for a
blob at that position beginning with "zzz/", the index cache is accessed
out of range, causing a segfault.

This kind of index state is not typically generated during user
operations, and is in fact an edge case of the state being checked for
in the conditional where it was added. However, since the entry for the
BUG() line is ambiguous, tell some additional context to help Git
developers debug the failure later. When we know the name of the dir we
were trying to look up, it becomes possible to examine the index file
in a hex util to determine what went wrong; the position gives a hint
about where to start looking.

4 years agorestore: invalidate cache-tree when removing entries with --staged

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).

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

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.

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

e83e71c5e1 ("sha1_file: refactor has_sha1_file_with_flags", 2017-06-26),
was introduced to preserve this difference in empty-tree handling, but

Elijah Newren [Wed, 1 Jan 2020 05:20:57 +0000 (05:20 +0000)] 
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: list directories in cone mode

When core.sparseCheckoutCone is enabled, the 'git sparse-checkout set'

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
