pipe_command(): mark stdin descriptor as non-blocking
Our pipe_command() helper lets you both write to and read from a child
process on its stdin/stdout. It's supposed to work without deadlocks
because we use poll() to check when descriptors are ready for reading or
writing. But there's a bug: if both the data to be written and the data
to be read back exceed the pipe buffer, we'll deadlock.
The issue is that the code assumes that if you have, say, a 2MB buffer
to write and poll() tells you that the pipe descriptor is ready for
writing, that calling:
write(cmd->in, buf, 2*1024*1024);
will do a partial write, filling the pipe buffer and then returning what
it did write. And that is what it would do on a socket, but not for a
pipe. When writing to a pipe, at least on Linux, it will block waiting
for the child process to read() more. And now we have a potential
deadlock, because the child may be writing back to us, waiting for us to
read() ourselves.
The diff against HEAD~200 will be big, and the filter wants to write all
of it back to us (obviously this is a dummy filter, but in the real
world something like diff-highlight would similarly stream back a big
output).
If you set add.interactive.useBuiltin to false, the problem goes away,
because now we're not using pipe_command() anymore (instead, that part
happens in perl). But this isn't a bug in the interactive code at all.
It's the underlying pipe_command() code which is broken, and has been
all along.
We presumably didn't notice because most calls only do input _or_
output, not both. And the few that do both, like gpg calls, may have
large inputs or outputs, but never both at the same time (e.g., consider
signing, which has a large payload but a small signature comes back).
The obvious fix is to put the descriptor into non-blocking mode, and
indeed, that makes the problem go away. Callers shouldn't need to
care, because they never see the descriptor (they hand us a buffer to
feed into it).
The included test fails reliably on Linux without this patch. Curiously,
it doesn't fail in our Windows CI environment, but has been reported to
do so for individual developers. It should pass in any environment after
this patch (courtesy of the compat/ layers added in the last few
commits).

pipe_command(): handle ENOSPC when writing to a pipe

something we want to correct, but given that we don't plan to use

pipe_command(): avoid xwrite() for writing to pipe
If xwrite() sees an EAGAIN response, it will loop forever until the
write succeeds (or encounters a real error). This is due to ef1cf0167a
(xwrite: poll on non-blocking FDs, 2016-06-26), with the idea that we
won't be surprised by a descriptor unexpectedly set as non-blocking.
But that will make things awkward when we do want a non-blocking
descriptor, and a future patch will switch pipe_command() to using one.
In that case, looping on EAGAIN is bad, because the process on the other
end of the pipe may be waiting on us before doing another read() on the
pipe, which would mean we deadlock.
In practice we're not supposed to ever see EAGAIN here, since poll()
will have just told us the descriptor is ready for writing. But our
Windows emulation of poll() will always return "ready" for writing to a
pipe descriptor! This is due to 94f4d01932 (mingw: workaround for hangs
when sending STDIN, 2020-02-17).
Our best bet in that case is to keep handling other descriptors, as any
read() we do may allow the child command to make forward progress (i.e.,
its write() finishes, and then it read()s from its stdin, freeing up
space in the pipe buffer). This means we might busy-loop between poll()
and write() on Windows if the child command is slow to read our input,
but it's much better than the alternative of deadlocking.
In practice, this busy-looping should be rare:
- for small inputs, we'll just write the whole thing in a single
write() anyway, non-blocking or not
- for larger inputs where the child reads input and then processes it
before writing (e.g., gpg verifying a signature), we may make a few
extra write() calls that get EAGAIN during the initial write, but
once it has taken in the whole input, we'll correctly block waiting
to read back the data.
- for larger inputs where the child process is streaming output back
(like a diff filter), we'll likewise see some extra EAGAINs, but
most of them will be followed immediately by a read(), which will
let the child command make forward progress.
Of course it won't happen at all for now, since we don't yet use a
non-blocking pipe. This is just preparation for when we do.

We'd like to be able to make some of our pipes nonblocking so that

The interface is as narrow as possible to let platforms do what's
natural there (rather than having to implement fcntl() and a fake
O_NONBLOCK for example, or having to handle other types of descriptors).
The next commit will add Windows support, at which point we should be
covering all platforms in practice. But if we do find some other
platform without O_NONBLOCK, we'll return ENOSYS. Arguably we could just
trigger a build-time #error in this case, which would catch the problem
earlier. But since we're not planning to use this compat wrapper in many

platform than blocking compilation completely. Our test suite would

is_promisor_object(): fix use-after-free of tree buffer
Since commit fcc07e980b (is_promisor_object(): free tree buffer after
parsing, 2021-04-13), we'll always free the buffers attached to a
"struct tree" after searching them for promisor links. But there's an
important case where we don't want to do so: if somebody else is already
using the tree!
This can happen during a "rev-list --missing=allow-promisor" traversal
in a partial clone that is missing one or more trees or blobs. The
backtrace for the free looks like this:
We're in the middle of walking through the entries of a tree object via
process_tree_contents(). We see a blob (or it could even be another tree
entry) that we don't have, so we call is_promisor_object() to check it.
That function loops over all of the objects in the promisor packfile,
including the tree we're currently walking. When we're done with it
there, we free the tree buffer. But as we return to the walk in
process_tree_contents(), it's still holding on to a pointer to that
buffer, via its tree_desc iterator, and it accesses the freed memory.
Even a trivial use of "--missing=allow-promisor" triggers this problem,
as the included test demonstrates (it's just a vanilla --blob:none
clone).
We can detect this case by only freeing the tree buffer if it was
allocated on our behalf. This is a little tricky since that happens
inside parse_object(), and it doesn't tell us whether the object was
already parsed, or whether it allocated the buffer itself. But by
checking for an already-parsed tree beforehand, we can distinguish the
two cases.
That feels a little hacky, and does incur an extra lookup in the
object-hash table. But that cost is fairly minimal compared to actually
loading objects (and since we're iterating the whole pack here, we're
likely to be loading most objects, rather than reusing cached results).
It may also be a good direction for this function in general, as there
are other possible optimizations that rely on doing some analysis before
parsing:
- we could detect blobs and avoid reading their contents; they can't
link to other objects, but parse_object() doesn't know that we don't
care about checking their hashes.
- we could avoid allocating object structs entirely for most objects
(since we really only need them in the oidset), which would save
some memory.
- promisor commits could use the commit-graph rather than loading the
object from disk
This commit doesn't do any of those optimizations, but I think it argues
that this direction is reasonable, rather than relying on parse_object()
and trying to teach it to give us more information about whether it
parsed.
The included test fails reliably under SANITIZE=address just when
running "rev-list --missing=allow-promisor". Checking the output isn't
strictly necessary to detect the bug, but it seems like a reasonable
addition given the general lack of coverage for "allow-promisor" in the
test suite.

fsck: downgrade tree badFilemode to "info"
The previous commit un-broke the "badFileMode" check; before then it was
literally testing nothing. And as far as I can tell, it has been so
since the very initial version of fsck.
The current severity of "badFileMode" is just "warning". But in the
--strict mode used by transfer.fsckObjects, that is elevated to an
error. This will potentially cause hassle for users, because historical
objects with bad modes will suddenly start causing pushes to many server
operators to be rejected.
At the same time, these bogus modes aren't actually a big risk. Because
we canonicalize them everywhere besides fsck, they can't cause too much
mischief in the real world. The worst thing you can do is end up with
two almost-identical trees that have different hashes but are
interpreted the same. That will generally cause things to be inefficient
rather than wrong, and is a bug somebody working on a Git implementation
would want to fix, but probably not worth inconveniencing users by
refusing to push or fetch.
So let's downgrade this to "info" by default, which is our setting for
"mention this when fscking, but don't ever reject, even under strict
mode". If somebody really wants to be paranoid, they can still adjust
the level using config.

fsck: actually detect bad file modes in trees
We use the normal tree_desc code to iterate over trees in fsck, meaning
we only see the canonicalized modes it returns. And hence we'd never see
anything unexpected, since it will coerce literally any garbage into one
of our normal and accepted modes.
We can use the new RAW_MODES flag to see the real modes, and then use
the existing code to actually analyze them. The existing code is written
as allow-known-good, so there's not much point in testing a variety of
breakages. The one tested here should be S_IFREG but with nonsense
permissions.
Do note that the error-reporting here isn't great. We don't mention the
specific bad mode, but just that the tree has one or more broken modes.
But when you go to look at it with "git ls-tree", we'll report the
canonicalized mode! This isn't ideal, but given that this should come up
rarely, and that any number of other tree corruptions might force you
into looking at the binary bytes via "cat-file", it's not the end of the

tree-walk: add a mechanism for getting non-canonicalized modes
When using init_tree_desc() and tree_entry() to iterate over a tree, we
always canonicalize the modes coming out of the tree. This is a good
thing to prevent bugs or oddities in normal code paths, but it's
counter-productive for tools like fsck that want to see the exact
contents.
We can address this by adding an option to avoid the extra
canonicalization. A few notes on the implementation:
- I've attached the new option to the tree_desc struct itself. The
actual code change is in decode_tree_entry(), which is in turn
called by the public update_tree_entry(), tree_entry(), and
init_tree_desc() functions, plus their "gently" counterparts.
By letting it ride along in the struct, we can avoid changing the
signature of those functions, which are called many times. Plus it's
conceptually simpler: you really want a particular iteration of a
tree to be "raw" or not, rather than individual calls.
- We still have to set the new option somewhere. The struct is
initialized by init_tree_desc(). I added the new flags field only to
the "gently" version. That avoids disturbing the much more numerous
non-gentle callers, and it makes sense that anybody being careful
about looking at raw modes would also be careful about bogus trees
(i.e., the caller will be something like fsck in the first place).

mergetools: vimdiff: fix single window layouts
Layouts with a single window other than "MERGED" do not work (e.g.
"LOCAL" or "MERGED+LOCAL").
This is because as the documentation of bufdo says:
The last buffer (or where an error occurred) becomes the current
buffer.
And we do always do bufdo the end.
Additionally, we do it only once, when it should be per tab.
Fix this by doing it once per tab right after it's created and before
any buffer is switched.

mergetools: vimdiff: make vimdiff3 actually work
When vimdiff3 was added in 7c147b77d3 (mergetools: add vimdiff3 mode,
2014-04-20), the description made clear the intention:
It's similar to the default, except that the other windows are
hidden. This ensures that removed/added colors are still visible on
the main merge window, but the other windows not visible.
However, in 0041797449 (vimdiff: new implementation with layout support,

windows, and therefore vim never shows the diff.
The layout support implementation broke the whole purpose of vimdiff3,
and simply shows MERGED, which is no different from simply opening the
file with vim.
In order to show the diff, the windows need to be created first, and
then when they are hidden the diff remains (if hidenoff isn't set), but
by setting the `hidden` option the initial buffers are marked as hidden
thus making the feature work.

unpack-trees: unpack new trees as sparse directories
If 'unpack_single_entry()' is unpacking a new directory tree (that is, one
not already present in the index) into a sparse index, unpack the tree as a
sparse directory rather than traversing its contents and unpacking each file
individually. This helps keep the sparse index as collapsed as possible in
cases such as 'git reset --hard' restoring a outside-of-cone directory
removed with 'git rm -r --sparse'.
Without this patch, 'unpack_single_entry()' will only unpack a directory
into the index as a sparse directory (rather than traversing into it and
unpacking its files one-by-one) if an entry with the same name already
exists in the index. This patch allows sparse directory unpacking without a
matching index entry when the following conditions are met:
1. the directory's path is outside the sparse cone, and
2. there are no children of the directory in the index
If a directory meets these requirements (as determined by
'is_new_sparse_dir()'), 'unpack_single_entry()' unpacks the sparse directory
index entry and propagates the decision back up to 'unpack_callback()' to
prevent unnecessary tree traversal into the unpacked directory.

mingw: handle a file owned by the Administrators group correctly
When an Administrator creates a file or directory, the created
file/directory is owned not by the Administrator SID, but by the
_Administrators Group_ SID. The reason is that users with administrator
privileges usually run in unprivileged ("non-elevated") mode, and their
user SID does not change when running in elevated mode.
This is is relevant e.g. when running a GitHub workflow on a build
agent, which runs in elevated mode: cloning a Git repository in a script
step will cause the worktree to be owned by the Administrators Group
SID, for example.
Let's handle this case as following: if the current user is an
administrator, Git should consider a worktree owned by the
Administrators Group as if it were owned by said user.

Fix a logic error in a082345372e (hook API: fix v2.36.0 regression:
hooks should be connected to a TTY, 2022-06-07). When it started using
the "ungroup" API added in fd3aaf53f71 (run-command: add an "ungroup"
option to run_process_parallel(), 2022-06-07) it should have made the
same sort of change that fd3aaf53f71 itself made in
"t/helper/test-run-command.c".
The correct way to emit this "Couldn't start" output with "ungroup"
would be:
But we should instead remove the emitting of this output. As the added
test shows we already emit output when we can't run the child. The
"cannot run" output here is emitted by run-command.c's
child_err_spew().
So the addition of the "Couldn't start hook" output here in 96e7225b310 (hook: add 'run' subcommand, 2021-12-22) was always
redundant. For the pre-commit hook we'll now emit exactly the same
output as we did before f443246b9f2 (commit: convert
{pre-commit,prepare-commit-msg} hook to hook.h, 2021-12-22) (and
likewise for others).
We could at this point add this to the pick_next_hook() callbacks in
hook.c:
assert(!out);
assert(!*pp_task_cb);
And this to notify_start_failure() and notify_hook_finished() (in the
latter case the parameter is called "pp_task_cp"):
assert(!out);
assert(!pp_task_cb);
But let's leave any such instrumentation for some eventual cleanup of
the "ungroup" API.

Files' attributes can indicate more than just whether they are files or
directories. It was reported in Git for Windows that on certain network
shares, this led to a nasty problem trying to create tags:
$ git tag -a -m "automatic tag creation" test_dir/test_tag
fatal: cannot lock ref 'refs/tags/test_dir/test_tag': unable to resolve reference 'refs/tags/test_dir/test_tag': Not a directory
Note: This does not necessarily happen with all types of network shares.
One setup where it _did_ happen is a Windows Server 2019 VM, and as
hinted in
This would impact performance negatively, though, as it essentially
turns off all caching, therefore we do not want to require users to do
that just to be able to use Git on Windows.
The underlying bug is in the code added in 4b0abd5c695 (mingw: let
lstat() fail with errno == ENOTDIR when appropriate, 2016-01-26) that
emulates the POSIX behavior where `lstat()` should return `ENOENT` if
the file or directory simply does not exist but could be created, and
`ENOTDIR` if there is no file or directory nor could there be because a
leading path already exists and is not a directory.
In that code, the return value of `GetFileAttributesW()` is interpreted
as an enum value, not as a bit field, so that a perfectly fine leading
directory can be misdetected as "not a directory".
As a consequence, the `read_refs_internal()` function would return
`ENOTDIR`, suggesting not only that the tag in the `git tag` invocation
above does not exist, but that it cannot even be created.
Let's fix the code so that it interprets the return value of the
`GetFileAttributesW()` call correctly.

windows: include the Python bits when building Git for Windows
While Git for Windows does not _ship_ Python (in order to save on
bandwidth), MSYS2 provides very fine Python interpreters that users can
easily take advantage of, by using Git for Windows within its SDK.
Previously, we excluded the Python bits, mostly due to historical
reasons: In the Git for Windows v1.x days, we built Git using
MSys/MinGW, without support for any Python scripts.
Therefore, let's move out the `NO_PYTHON` definition from the generic
part of the MINGW section (which includes special handling for MSYS2/Git
