Avoid 32-bit size_t overflow when reporting the available disk space in
'get_disk_info' by casting the block size and available block count to
'off_t' before multiplying them. Without this change, 'st_mult' would
(correctly) report a size_t overflow on 32-bit systems at or exceeding 2^32
bytes of available space.
Note that 'off_t' is a 64-bit integer even on 32-bit systems due to the
inclusion of '#define _FILE_OFFSET_BITS 64' in 'git-compat-util.h' (see
b97e911643 (Support for large files on 32bit systems., 2007-02-17)).

Though perhaps not common, there are use cases where users have large,

network paths would benefit those users.
Most modern Samba-based filers have the necessary support to enable
fsmonitor on network-mounted repos. As a first step towards enabling
fsmonitor to work against network-mounted repos, introduce a
configuration option, 'fsmonitor.allowRemote'. Setting this option to

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.

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
world. And it's something we can improve on top later if we choose.

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).

A previous change added the '--bundle-uri' option, but did not check
if the --depth parameter was included. Since bundles are not compatible
with shallow clones, provide an error message to the user who is
attempting this combination.
I am leaving this as its own change, separate from the one that
implements '--bundle-uri', because this is more of an advisory for the
user. There is nothing wrong with bootstrapping with bundles and then
fetching a shallow clone. However, that is likely going to involve too
much work for the client _and_ the server. The client will download all
of this bundle information containing the full history of the
repository only to ignore most of it. The server will get a shallow
fetch request, but with a list of haves that might cause a more painful
computation of that shallow pack-file.

Cloning a remote repository is one of the most expensive operations in
Git. The server can spend a lot of CPU time generating a pack-file for
the client's request. The amount of data can clog the network for a long
time, and the Git protocol is not resumable. For users with poor network
connections or are located far away from the origin server, this can be
especially painful.
Add a new '--bundle-uri' option to 'git clone' to bootstrap a clone from
a bundle. If the user is aware of a bundle server, then they can tell
Git to bootstrap the new repository with these bundles before fetching
the remaining objects from the origin server.

Before implementing a way to fetch bundles into a repository, create the
basic logic. Assume that the URI is actually a file path. Future logic
will make this more careful to other protocols.
For now, we also only succeed if the content at the URI is a bundle
file, not a bundle list. Bundle lists will be implemented in a future
change.
Note that the discovery of a temporary filename is slightly racy because
the odb_mkstemp() relies on the temporary file not existing. With the
current implementation being limited to file copies, we could replace
the copy_file() with copy_fd(). The tricky part comes in future changes
that send the filename to 'git remote-https' and its 'get' capability.
At that point, we need the file descriptor closed _and_ the file
unlinked. If we were to keep the file descriptor open for the sake of
normal file copies, then we would pollute the rest of the code for
little benefit. This is especially the case because we expect that most
bundle URI use will be based on HTTPS instead of file copies.

to organize Git object data and speed up clones and fetches. It is
particularly important that we have flexibility so we can apply future

However, the design document does not provide even an example of how
bundles could be organized, and that makes it difficult to envision how

Add a section that details how a bundle provider could work, including

Originally, moving an in-cone <source> to an out-of-cone <destination>
was not possible, mainly because such <destination> is a directory that
is not present in the working tree.
Change the behavior so that we can move an in-cone <source> to
out-of-cone <destination> when --sparse is supplied.
Notice that <destination> can also be an out-of-cone file path, rather
than a directory.
Such <source> can be either clean or dirty, and moving it results in
different behaviors:
A clean move should move <source> to <destination> in the index (do
*not* create <destination> in the worktree), then delete <source> from
the worktree.
A dirty move should move the <source> to the <destination>, both in the
working tree and the index, but should *not* remove the resulted path
from the working tree and should *not* turn on its CE_SKIP_WORKTREE bit.
Optional reading
================
We are strict about cone mode when <destination> is a file path.
The reason is that some of the previous tests that use no-cone mode in
t7002 are keep breaking, mainly because the `dst_mode = SPARSE;` line
added in this patch.
Most features developed in both "from-out-to-in" and "from-in-to-out"
only care about cone mode situation, as no-cone mode is becoming
irrelevant. And because assigning `SPARSE` to `dst_mode` when the
repo is in no-cone mode causes miscellaneous bugs, we should just leave
this new functionality to be exclusive cone mode and save some time.

Originally, <destination> is assumed to be in the working tree. If it is
not found as a directory, then it is determined to be either a regular file
path, or error out if used under the second form (move into a directory)
of 'git-mv'. Such behavior is not ideal, mainly because Git does not
look into the index for <destination>, which could potentially be a
SKIP_WORKTREE_DIR, which we need to determine for the later "moving from
in-cone to out-of-cone" patch.
Change the logic so that Git first check if <destination> is a directory
with all its contents sparsified (a SKIP_WORKTREE_DIR).
If <destination> is such a sparse directory, then we should modify the
index the same way as we would if this were a non-sparse directory. We
must be careful to ensure that the <destination> is marked with
SKIP_WORKTREE_DIR.
Also add a `dst_w_slash` to reuse the result from `add_slash()`, which
was everywhere and can be simplified.

It's similar to the default, except that the other windows are

However, in 0041797449 (vimdiff: new implementation with layout support,
2022-03-30) this was broken by generating a command that never creates
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
