Support hierarchical test resource data, such that you can have
`tests/resources/foo/bar` and move the `bar` directory in as
a fixture.
Calling `cl_fixture_sandbox` on a path that is not directly beneath
the test resources directory succeeds, placing that directory into
the test fixture. (For example, `cl_fixture_sandbox("foo/bar")`
will sandbox the `foo/bar` directory as `bar`).
Add support for cleaning up directories created this way, by only
cleaning up the basename (in this example, `bar`) from the fixture
directory.
Given a variety of combinations of core.autocrlf settings and
attributes settings, test that we check out data into the working
directory the same as a known-good test resource created by git.git.
We currently do not handle those enum values which require us to set
"true" or unset variables in all cases. Use a common function which does
understand this by looking at our mapping directly.
The current code will always fail, but only because it's asking for a
string on a live config. Take a snapshot and make sure we fail with
ENOTFOUND instead of any old error.
Similarly to the other ones. In this test we copy over testing
`RECURSE_YES` which shows an error in our handling of the `YES` variant
which we may have to port to the rest.
During the cache deletion, the check for whether we consider a submodule
to exist got changed regarding submodules which are in the worktree but
not configured.
Instead of checking for the url field to be populated, check the
location where we've found it.
This lets us specify in the status call which ignore rules we want to
use (optionally falling back to whatever the submodule has in its
configuration).
This removes one of the reasons for having `_set_ignore()` set the value
in-memory. We re-use the `IGNORE_RESET` value for this as it is no
longer relevant but has a similar purpose to `IGNORE_FALLBACK`.
Similarly, we remove `IGNORE_DEFAULT` which does not have use outside of
initializers and move that to fall back to the configuration as well.
As submodules are becomes more like values, we should not let a status
check to update its properties. Instead of taking a submodule, have
status take a repo and submodule name.
Having this cache and giving them out goes against our multithreading
guarantees and it makes it impossible to use submodules in a
multi-threaded environment, as any thread can ask for a refresh which
may reallocate some string in the submodule struct which we've accessed
in a different one via a getter.
This makes the submodules behave more like remotes, where each object is
created upon request and not shared except explicitly by the user. This
means that some tests won't pass yet, as they assume they can affect the
submodule objects in the cache and that will affect later operations.
As we attempt to replicate a situation in which an older checkout has
put a file on disk with different filtering settings from us, set the
timestamp on the entry and file to a second before we're performing the
operation so the entry in the index counts as old.
This way we can test that we're not looking at the on-disk file when the
index has the entry and we detect it as clean.
This allows the user to look up fields which we don't parse in libgit2,
and allows them to access gpgsig or mergetag fields if they wish to
check the signature.
When an entry has a racy timestamp, we need to check whether the file
itself has changed since we put its entry in the index. Only then do we
smudge the size field to force a check the next time around.
When a file on the workdir has the same or a newer timestamp than the
index, we need to perform a full check of the contents, as the update of
the file may have happened just after we wrote the index.
The iterator changes are such that we can reach inside the workdir
iterator from the diff, though it may be better to have an accessor
instead of moving these structs into the header.
When updating the index during a diff, preserve the original mode,
which prevents us from dropping the mode to what we have interpreted
as on our system (eg, what the working directory claims it to be,
which may be a lie on some systems.)
This is used by the submodule in order to figure out if the index has
changed since it last read it. Using a timestamp is racy, so let's make
it use the checksum, just like we now do for reloading the index itself.
