I have two repos: ci-test and ci-test2. The ci-test repo contains a CI.yaml file and the ci-test2 repo is empty. Using mgit, I am performing a sparse checkout of only the CI.yaml file on both repos and I get the error, "Sparse checkout leaves no entry on working directory". I am almost sure that this happens because I am trying to checkout the file in the ci-test2 repo which does not contain it. I was wondering if there is a way to gracefully handle this error, perhaps by looking into git read-tree. This is just an example, I have many more repos than this and my mgit checkout class does not know anything about the contents of my repos. Does anybody have an idea?
Even before the sparse checkout itself, you could check if the remote repository has the CI.yaml file: see "How do I check if a file exists in a remote?".
But if you already have fetched the repository (and only need to checkout/restore one file in it), a git cat-file -e could work:
-eExit with zero status if
<object>exists and is a valid object.
If<object>is of an invalid format, exit with non-zero and emits an error on stderr.
