Single perforce branch might be sync'ed multiple times with different
revision numbers, so it will be seen to Git as complete different
commits. This can be done by the following command:
git p4 sync --branch=NAME //perforce/path...
It is assumed, that this command applied multiple times and
peforce repository changes between command invocations.
In such situation, git p4 will see multiple perforce branches with
same name and different revision numbers. The problem is that to make
a shelve, git-p4 script will try to find "origin" branch, if not
specified in command line explicitly. And previously script selected
any branch with same name and don't mention particular revision number.
Later this may cause failure of the command "git diff-tree -r $rev^ $rev",
so shelve can't be created (due to wrong origin branch/commit).
This commit fixes the heuristic by which git p4 selects origin branch:
first it tries to select branch with same perforce path and perforce
revision, and if it fails, then selects branch with only same perforce
path (ignoring perforce revision number).

It poses a security risk to search for a git directory outside of the
directories owned by the current user.
For example, it is common e.g. in computer pools of educational
institutes to have a "scratch" space: a mounted disk with plenty of
space that is regularly swiped where any authenticated user can create
a directory to do their work. Merely navigating to such a space with a
Git-enabled `PS1` when there is a maliciously-crafted `/scratch/.git/`
can lead to a compromised account.
The same holds true in multi-user setups running Windows, as `C:\` is
writable to every authenticated user by default.
To plug this vulnerability, we stop Git from accepting top-level
directories owned by someone other than the current user. We avoid
looking at the ownership of each and every directories between the
current and the top-level one (if there are any between) to avoid
introducing a performance bottleneck.
This new default behavior is obviously incompatible with the concept of
shared repositories, where we expect the top-level directory to be owned
by only one of its legitimate users. To re-enable that use case, we add
support for adding exceptions from the new default behavior via the
config setting `safe.directory`.
The `safe.directory` config setting is only respected in the system and
global configs, not from repository configs or via the command-line, and
can have multiple values to allow for multiple shared repositories.
We are particularly careful to provide a helpful message to any user
trying to use a shared repository.

This function will be used in the next commit to prevent
`setup_git_directory()` from discovering a repository in a directory
that is owned by someone other than the current user.
Note: We cannot simply use `st.st_uid` on Windows just like we do on
Linux and other Unix-like platforms: according to
https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/stat-functions
this field is always zero on Windows (because Windows' idea of a user ID
does not fit into a single numerical value). Therefore, we have to do
something a little involved to replicate the same functionality there.
Also note: On Windows, a user's home directory is not actually owned by
said user, but by the administrator. For all practical purposes, it is
under the user's control, though, therefore we pretend that it is owned
by the user.

"git rebase A B" where B is not a commit should behave as if the
HEAD got detached at B and then the detached HEAD got rebased on top
of A. A bug however overwrites the current branch to point at B,
when B is a descendant of A (i.e. the rebase ends up being a
fast-forward). See [1] for the original bug report.
The callstack from checkout_up_to_date() is the following:
cmd_rebase()
-> checkout_up_to_date()
-> reset_head()
-> update_refs()
-> update_ref()
When B is not a valid branch but an oid, rebase sets the head_name
of rebase_options to NULL. This value gets passed down this call
chain through the branch member of reset_head_opts also getting set
to NULL all the way to update_refs().
Then update_refs() checks ropts.branch to decide whether or not to switch
branches. If ropts.branch is NULL, it calls update_ref() to update HEAD.
At this point however, from rebase's point of view, we want a detached
HEAD. But, since checkout_up_to_date() does not set the RESET_HEAD_DETACH
flag, the update_ref() call will deference HEAD and update the branch its
pointing to. We want the HEAD detached at B instead.
Fix this bug by adding the RESET_HEAD_DETACH flag in
checkout_up_to_date if B is not a valid branch, so that once
reset_head() calls update_refs(), it calls update_ref() with
REF_NO_DEREF which updates HEAD directly intead of deferencing it
and updating the branch that HEAD points to.
Also add a test to ensure the correct behavior.

To prepare for the next commit that will test rebase with oids instead
of branch names, update the rebase setup test to add a couple of tags we
can use. This uses the test_commit helper so we can replace some lines
that add a commit manually.

Change the "reflog exists" command added in afcb2e7a3b8 (git-reflog:

own custom command-line parser. This continues work started in

When reset_repository_shallow() is called, Git clears its cache of
shallow information, so that if shallow information is re-requested, Git
will read fresh data from disk instead of reusing its stale cached data.
However, the cache of commit grafts is not likewise cleared, even though
there are commit grafts created from shallow information.
This means that if on-disk shallow information were to be updated and
then a commit-graft-using codepath were run (for example, a revision
walk), Git would be using stale commit graft information. This can be
seen from the test in this patch, in which Git performs a revision walk
(to check for changed submodules) after a fetch with --update-shallow.
Therefore, clear the cache of commit grafts whenever
reset_repository_shallow() is called.

In cd475b3b038 (refs: add ability for backends to special-case reading
of symbolic refs, 2022-03-01) when the "read_symbolic_ref" callback
was added we'd fall back on "refs_read_raw_ref" if there wasn't any
backend implementation of "read_symbolic_ref".
As discussed in the preceding commit this would only happen if we were
running the "debug" backend, e.g. in the "setup for ref completion"
test in t9902-completion.sh with:
GIT_TRACE_REFS=1 git fetch --no-tags other
Let's improve the trace output, but and also eliminate the
now-redundant refs_read_raw_ref() fallback case. As noted in the
preceding commit the "packed" backend will never call
refs_read_symbolic_ref() (nor is it ever going to). For any future
backend such as reftable it's OK to ask that they either implement
this (or a wrapper) themselves.

Remove the stub BUG(...) functions previously used by the "struct
ref_storage_be refs_be_packed" backend.
We never call any functions in the packed backend by using it as a
"normal" primary ref store, instead we'll always initialize a "files"
backend ref-store.
It will then via the "packed_ref_store" member of "struct
files_ref_store" call selected functions in the "packed" backend, and
we'll in addition call others via wrappers in refs.c.
So while these would arguably give us *slightly* more meaningful error
messages we'll NULL the missing members in the initializer anyway, so
we'll reliably get a segfault if we're ever changing the backend and
having it call something it doesn't have.
So there's no need for this verbose boilerplate, and as shown in a
subsequent commit it might even lead to some confusion about the
packed backend being a "real" backend. Let's make it clear that it's
not.
As an aside, this also fixes a warning emitted by SunCC in at least

Change the definition of the three refs backends we currently carry to

The "= NULL" assignments being retained here are redundant, and could
be removed, but let's keep them for clarity. All of these backends
define almost all fields, so we're not saving much in terms of line
count by omitting these, but e.g. for "refs_be_debug" it's immediately

This reverts commit f2a454e0a5 (unpack-trees: improve performance of
next_cache_entry, 2021-11-29).
The "hint" value was originally needed to improve performance in 'git reset
-- <pathspec>' caused by 'cache_bottom' lagging behind its correct value
when using a sparse index. The 'cache_bottom' tracking has since been
corrected, removing the need for an additional "pseudo-cache_bottom"
tracking variable.

Correct tracking of the 'cache_bottom' for cases where sparse directories
are present in the index.
BACKGROUND
----------
The 'unpack_trees_options.cache_bottom' is a variable that tracks the
in-progress "bottom" of the cache as 'unpack_trees()' iterates through the
contents of the index. Most importantly, this value informs the sequential
return values of 'next_cache_entry()' which, in the "diff cache" usage of
'unpack_callback()', are either unpacked as-is or are passed into the diff
machinery.
The 'cache_bottom' is intended to track the position of the first entry in
the index that has not yet been diffed or unpacked. It is advanced in two
main ways: either it is incremented when an index entry is marked as "used"
(in 'mark_ce_used()'), indicating that it was unpacked or diffed, or when a
directory is unpacked, in which case it is increased by an amount equaling
the number of index entries inside that tree.
In 17a1bb570b (unpack-trees: preserve cache_bottom, 2021-07-14), it was
identified that sparse directories posed a problem to the above
'cache_bottom' advancement logic - because a sparse directory was both an
index entry that could be "used" and a directory that can be unpacked, the
'cache_bottom' would be incremented too many times. To solve this problem,
the 'mark_ce_used()' advancement of 'cache_bottom' was skipped for sparse
directories.
INCORRECT CACHE_BOTTOM TRACKING
-------------------------------
Skipping the 'cache_bottom' advancement for sparse directories in
'mark_ce_used()' breaks down in two cases:
1. When the 'unpack_trees()' operation is *not* a "cache diff" (because the
directory contents-based incrementing of 'cache_bottom' does not happen).
2. When a cache diff is performed with a pathspec (because
'unpack_index_entry()' will unpack a sparse directory not matched by the
pathspec without performing the directory contents-based increment).
The former luckily does not appear to affect 'git' behavior, likely because
'cache_bottom' is largely unused (non-"cache diff" 'unpack_trees()' uses
'find_index_entry()' - rather than 'next_cache_entry()' - to find the index
entries to unpack).
The latter, however, causes 'cache_bottom' to "lag behind" its intended
position by an amount equal to the number of sparse directories unpacked so
far with 'unpack_index_entry()'. If a repository is structured such that any
sparse directories are ordered lexicographically *after* any
pathspec-matching directories, though, this issue won't present any adverse
behavior.
This was the case with the 't1092-sparse-checkout-compatibility.sh' tests
before the addition of the 'before/' sparse directory (ordered *before* the
in-cone 'deep/' directory), therefore sidestepping the issue. Once the
'before/' directory was added, though, 'cache_bottom' began to lag behind
its intended position, causing 'next_cache_entry()' to return index entries
it had already processed and, ultimately, an incorrect diff.
CORRECTING CACHE_BOTTOM
-----------------------
The problems observed in 't1092' come from 'cache_bottom' lagging behind in
cases where the cache tree-based advancement doesn't occur. To solve this,
then, the fix in 17a1bb570b is "reversed"; rather than skipping
'cache_bottom' advancement in 'mark_ce_used()', we skip the directory
contents-based advancement for sparse directories. Now, every index entry
can be accounted for in 'cache_bottom':
* if you're working with a single index entry, 'cache_bottom' is incremented
in 'mark_ce_used()'
* if you're working with a directory that contains index entries (but is not
one itself), 'cache_bottom' is incremented by the number of entries in
that directory.
Finally, change the 'test_expect_failure' tests in 't1092' failing due to
this bug back to 'test_expect_success'.

Add a sparse directory 'before/' containing files 'a' and 'b' to the test
repo used in 't/t1092-sparse-checkout-compatibility.sh'. This is meant to
ensure that no sparse index integrations rely on the in-cone path(s) being
lexicographically first in the repo.
Unfortunately, some existing tests do not handle this repo architecture
properly:
* 'add outside sparse cone'
* 'status/add: outside sparse cone'
* 'reset with pathspecs inside sparse definition'
All three of these are due to the incorrect handling of the
'unpack_trees_options.cache_bottom' when performing a cache diff via
'unpack_trees'. This will be corrected in a future patch; in the meantime,
mark the tests with 'test_expect_failure'.
Finally, update the 'ls-files' and 'root directory cannot be sparse' tests
to include the 'before/' directory in their expected index contents.

My a18d66cefb9 (diff.c: free "buf" in diff_words_flush(), 2022-03-04)
has what it retrospect is a rather obvious bug (I don't know what I
was thinking, if it all): We use the "emitted_symbols" allocation in
append_emitted_diff_symbol() N times, but starting with a18d66cefb9
we'd free it after its first use!
The correct way to free this data would have been to add the free() to
the existing free_diff_words_data() function, so let's do that. The
"ecbdata->diff_words->opt->emitted_symbols" might be NULL, so let's
add a trivial free_emitted_diff_symbols() helper next to the function
that appends to it.
This fixes the "no effect on show from" leak tested for in the
preceding commit. Perhaps confusingly this change will skip that test
under SANITIZE=leak, but otherwise opt-in the
"t4015-diff-whitespace.sh" test.
The reason is that a18d66cefb9 "fixed" the leak in the preceding "no
effect on diff" test, but for the first call to diff_words_flush() the
"wol->buf" would be NULL, so we wouldn't double-free (and
SANITIZE=address would see nothing amiss). With this change we'll
still pass that test, showing that we've also fixed leaks on this
codepath.
We then have to skip the new "no effect on show" test because it
happens to trip over an unrelated memory leak (in revision.c). The
same goes for "move detection with submodules". Both of them pass with
SANITIZE=address though, which would error on the "no effect on show"
test before this change.

Change tests that used a "mkdir -p .git/hooks && write_script" pattern
to use the new "test_hook" helper instead. The new helper does not
create the .git/hooks directory, rather we assume that the default
template will do so for us.
An upcoming series[1] will extend "test_hook" to operate in a
"--template=" mode, but for now assuming that we have a .git/hooks
already is a safe assumption. If that assumption becomes false in the
future we'll only need to change 'test_hook", instead of all of these
callsites.

Refactor various test code to use the "test_hook" helper. This change:
- Fixes the long-standing issues with those tests using "#!/bin/sh"
instead of "#!$SHELL_PATH". Using "#!/bin/sh" here happened to work
because this code was so simple that it e.g. worked on Solaris
/bin/sh.
- Removes the "mkdir .git/hooks" invocation, as explained in a
preceding commit we'll rely on the default templates to create that
directory for us.
For the test in "t5402-post-merge-hook.sh" it's easier and more
correct to unroll the for-loop into a test_expect_success, so let's do
that.

Refactor the repository setup code for tests that test hooks the use
of sub-shells when setting up the test repository and hooks, and use
the "test_hook" wrapper instead of "write_scripts".

Change the "t5516-fetch-push.sh" test code to make use of the new
"test_hook" helper, and to use "test_when_finished" to have tests
clean up their own state, instead of relying on subsequent tests to
clean the trash directory.
Before this each test would have been responsible for cleaning up
after a preceding test (which may or may not have run, e.g. if --run
or "GIT_SKIP_TESTS" was used), now each test will instead clean up
after itself.
In order to use both "test_hook" and "test_when_finished" we need to
move them out of sub-shells, which requires some refactoring.
While we're at it split up the "push with negotiation" test, now the
middle of the test doesn't need to "rm event", and since it delimited
two halves that were testing two different things the end-state is
easier to read and reason about.
While changing these lines make the minor change from "-fr" to "-rf"
as the "rm" argument, some of them used it already, it's more common
in the test suite, and it leaves the end-state of the file with more
consistency.

Amend a test added in 788a776069b (bugreport: collect list of
populated hooks, 2020-05-07) to "test_cmp" for the expected output,
instead of selectively using "grep" to check for specific things we
either expect or don't expect in the output.
As noted in a preceding commit our .git/hooks directory already
contains *.sample hooks, so we have no need to clobber the
prepare-commit-msg.sample hook in particular.
Instead we should assert that those *.sample hooks are not included in
the output, and for good measure let's add a new "unknown-hook", to
check that we only look through our own known hooks. See
cfe853e66be (hook-list.h: add a generated list of hooks, like
config-list.h, 2021-09-26) for how we generate that data.
We're intentionally not piping the "actual" output through "sort" or
similar, we'd also like to check that our reported hooks are sorted.

Stop moving the .git/hooks directory out of the way, or creating it
during test setup. Instead assume that it will contain
harmless *.sample files.
That we can assume that is discussed in point #4 of
f0d4d398e28 (test-lib: split up and deprecate test_create_repo(),
2021-05-10), those parts of this could and should have been done in
that change.
Removing the "mkdir -p" here will then validate that our templates are
being used, since we'd subsequently fail to create a hook in that
directory if it didn't exist. Subsequent commits will have those hooks
created by a "test_hook" wrapper, which will then being doing that
same validation.

Change code added in a87679339c0 (test: rename http fetch and push
test files, 2014-02-06) to stop relying on the "exec git
update-server-info" in "templates/hooks--post-update.sample", let's
instead inline the expected hook in the test itself.

Add a "test_hook" wrapper similar to the existing "test_config"
wrapper added in d960c47a881 (test-lib: add helper functions for
config, 2011-08-17).
This wrapper:
- Will clean up the hook with "test_when_finished", unless --setup is
provided.
- Will error if we clobber a hook, unless --clobber is provided.
- Takes a name like "update" instead of ".git/hooks/update".
- Accepts -C <dir>, like "test_config" and "test_commit".
By using a wrapper we'll be able to easily change all the hook-related
code that assumes that the template-created ".git/hooks" directory is
created by "init", "clone" etc. once another topic follows-up and
changes the test suite to stop creating trash directories using those
templates.
In addition this will make it easy to have the hooks configured using
the "configuration-based hooks" topic, once we get around to
integrating that. I.e. we'll be able to run the tests in a mode where
we sometimes create a .git/hooks/<name>, and other times create a
script in another location, and point the relevant configuration
snippet to it.

Build fix on Windows.

mingw: avoid fallback for {local,gm}time_r()

mingw-w64's pthread_unistd.h had a bug that mistakenly (because there is
no support for the *lockfile() functions required[1]) defined
_POSIX_THREAD_SAFE_FUNCTIONS and that was being worked around since
3ecd153a3b (compat/mingw: support MSys2-based MinGW build, 2016-01-14).
The bug was fixed in winphtreads, but as a side effect, leaves the
reentrant functions from time.h no longer visible and therefore breaks
the build.
Since the intention all along was to avoid using the fallback functions,
formalize the use of POSIX by setting the corresponding feature flag and
compile out the implementation for the fallback functions.
