Replace xfail with gc.collect in TestSubmodule.test_rename #1767

In various places in the code, a conditional gc.collect() is used to allow a test to finish its work (and pass). This adds one more such place. It accordingly removes an xfail marking. TestSubmodule.test_rename now passes on all combinations of platform and Python version.

Like the xfail condition, running gc.collect() here is conditional, being done only in the specific situation the PermissionError occurs. Besides that it does not always run even on Windows (only in 3.12 and later), this resembles various other conditional and non-conditional gc.collect calls.

The situation is a bit odd, but I think that's--albeit by a fairly slight margin--more of a reason to convert the xfail into a gc.collect() than to refrain from doing so.

Context

#1745 (under "Which versions should we test?"), and also 82c361e, 0b7ee17, and various other less interesting commits, provide further context about this test and the PermissionError on Windows that does not occur prior to 3.12.

Because PermissionError error message is about another process having the file open, #790 seems relevant. But this does not happen in a call to git.util.rmtree.

One call is enough, now

It had previously appeared to me that two calls to gc.collect were required, but I am unable to reproduce that. It may have been specific to how I was running it on my system at that time. The need for only one call may have been brought about by changes to the code in the mean time, but I have tested that only one call appears required even without the changes in #1765. (Perhaps #1753 contributed? I think most likely not, though.)

This is to clearly establish the failure still occurs (since we do
not have strict=True set). It is in preparation for working around
the problems with a call to gc.collect().

See 82c361e and 0b7ee17 for context.

That's a great catch! Who would have thought that gc.collect() is also applicable here.

This probably also hints at the need to eventually fix the way GitPython handles systems resources. After all, it really seems like one would rather want to use…

with git.open(path) as repo:
   pass

…to control the lifetime of all opened resources precisely. Alternatively, GitPython would not be allowed to keep anything open past the lifetime of a method call, but that's not feasible at all. Maybe there is alternatives that I am not seeing.

It's interesting how it's obvious that GitPython was designed in a time when there was no GC, but rather, reference counting with deterministic and immediate calls of destructors.

This sounds like it might be part of making the classes that currently have __del__ methods also be context managers, as discussed in comments in #1669. Though I suppose this usage need not wait for that, with Repo having been a context manager since #555. Should the tests be modified to make greater use of that? I'm not sure it would address the sort of thing that happened here and it's not quite what your code example shows.

It's interesting how it's obvious that GitPython was designed in a time when there was no GC, but rather, reference counting with deterministic and immediate calls of destructors.

I have some thoughts about how the effects of this might be mitigated, to some extent, even for existing code that would not use newly added context managers (or perhaps even before, or separately from, making more classes context managers). But right now these are half-formed ideas that might turn out to be meritless and (as with #1762) there's some other GitPython-related stuff I'd probably want to finish dealing with first. I mention this mainly so I don't forget or, if I do, so that it is more likely to come up again.

I left some more ideas in this comment, and based on it I'd say the tests should be kept as is. Should a full-on context-manager approach happen, the tests can be a great indicator to show how hard the migration would be for existing users, and also guide towards making it as painless as possible.

### GitHub Vulnerability Alerts

####
[CVE-2024-22190](https://togithub.com/gitpython-developers/GitPython/security/advisories/GHSA-2mqj-m65w-jghx)

### Summary

This issue exists because of an incomplete fix for CVE-2023-40590. On
Windows, GitPython uses an untrusted search path if it uses a shell to
run `git`, as well as when it runs `bash.exe` to interpret hooks. If
either of those features are used on Windows, a malicious `git.exe` or
`bash.exe` may be run from an untrusted repository.

### Details

Although GitPython often avoids executing programs found in an untrusted
search path since 3.1.33, two situations remain where this still occurs.
Either can allow arbitrary code execution under some circumstances.

#### When a shell is used

GitPython can be told to run `git` commands through a shell rather than
as direct subprocesses, by passing `shell=True` to any method that
accepts it, or by both setting `Git.USE_SHELL = True` and not passing
`shell=False`. Then the Windows `cmd.exe` shell process performs the
path search, and GitPython does not prevent that shell from finding and
running `git` in the current directory.

When GitPython runs `git` directly rather than through a shell, the
GitPython process performs the path search, and currently omits the
current directory by setting `NoDefaultCurrentDirectoryInExePath` in its
own environment during the `Popen` call. Although the `cmd.exe` shell
will honor this environment variable when present, GitPython does not
currently pass it into the shell subprocess's environment.

Furthermore, because GitPython sets the subprocess CWD to the root of a
repository's working tree, using a shell will run a malicious `git.exe`
in an untrusted repository even if GitPython itself is run from a
trusted location.

This also applies if `Git.execute` is called directly with `shell=True`
(or after `Git.USE_SHELL = True`) to run any command.

#### When hook scripts are run

On Windows, GitPython uses `bash.exe` to run hooks that appear to be
scripts. However, unlike when running `git`, no steps are taken to avoid
finding and running `bash.exe` in the current directory.

This allows the author of an untrusted fork or branch to cause a
malicious `bash.exe` to be run in some otherwise safe workflows. An
example of such a scenario is if the user installs a trusted hook while
on a trusted branch, then switches to an untrusted feature branch
(possibly from a fork) to review proposed changes. If the untrusted
feature branch contains a malicious `bash.exe` and the user's current
working directory is the working tree, and the user performs an action
that runs the hook, then although the hook itself is uncorrupted, it
runs with the malicious `bash.exe`.

Note that, while `bash.exe` is a shell, this is a separate scenario from
when `git` is run using the unrelated Windows `cmd.exe` shell.

### PoC

On Windows, create a `git.exe` file in a repository. Then create a
`Repo` object, and call any method through it (directly or indirectly)
that supports the `shell` keyword argument with `shell=True`:

```powershell
mkdir testrepo
git init testrepo
cp ... testrepo git.exe # Replace "..." with any executable of choice.
python -c "import git; print(git.Repo('testrepo').git.version(shell=True))"
```

The `git.exe` executable in the repository directory will be run.

Or use no `Repo` object, but do it from the location with the `git.exe`:

```powershell
cd testrepo
python -c "import git; print(git.Git().version(shell=True))"
```

The `git.exe` executable in the current directory will be run.

For the scenario with hooks, install a hook in a repository, create a
`bash.exe` file in the current directory, and perform an operation that
causes GitPython to attempt to run the hook:

```powershell
mkdir testrepo
cd testrepo
git init
mv .git/hooks/pre-commit.sample .git/hooks/pre-commit
cp ... bash.exe # Replace "..." with any executable of choice.
echo "Some text" >file.txt
git add file.txt
python -c "import git; git.Repo().index.commit('Some message')"
```

The `bash.exe` executable in the current directory will be run.

### Impact

The greatest impact is probably in applications that set `Git.USE_SHELL
= True` for historical reasons. (Undesired console windows had, in the
past, been created in some kinds of applications, when it was not used.)
Such an application may be vulnerable to arbitrary code execution from a
malicious repository, even with no other exacerbating conditions. This
is to say that, if a shell is used to run `git`, the full effect of
CVE-2023-40590 is still present. Furthermore, as noted above, running
the application itself from a trusted directory is not a sufficient
mitigation.

An application that does not direct GitPython to use a shell to run
`git` subprocesses thus avoids most of the risk. However, there is no
such straightforward way to prevent GitPython from running `bash.exe` to
interpret hooks. So while the conditions needed for that to be exploited
are more involved, it may be harder to mitigate decisively prior to
patching.

### Possible solutions

A straightforward approach would be to address each bug directly:

- When a shell is used, pass `NoDefaultCurrentDirectoryInExePath` into
the subprocess environment, because in that scenario the subprocess is
the `cmd.exe` shell that itself performs the path search.
- Set `NoDefaultCurrentDirectoryInExePath` in the GitPython process
environment during the `Popen` call made to run hooks with a `bash.exe`
subprocess.

These need only be done on Windows.
