示例1: isValidGitRepository
// isValidGitRepository checks to see if there is a git repository in the
// directory and if the repository is valid -- i.e. it has remotes or commits
func isValidGitRepository(fs util.FileSystem, dir string) (bool, error) {
gitPath := filepath.Join(strings.TrimPrefix(dir, "file://"), ".git")
fi, err := fs.Stat(gitPath)
if os.IsNotExist(err) {
// The directory is not a git repo, no error
return false, nil
}
if err != nil {
return false, err
}
if !fi.IsDir() {
gitPath, err = followGitSubmodule(fs, gitPath)
if err != nil {
return false, err
}
}
// Search the content of the .git directory for content
directories := [2]string{
filepath.Join(gitPath, "objects"),
filepath.Join(gitPath, "refs"),
}
// For the directories we search, if the git repo has been used, there will
// be some file. We don't just search the base git repository because of the
// hook samples that are normally generated with `git init`
isEmpty := true
for _, dir := range directories {
err := fs.Walk(dir, func(path string, info os.FileInfo, err error) error {
// If we find a file, the git directory is "not empty"
// We're looking for object blobs, and ref files
if info != nil && !info.IsDir() {
isEmpty = false
return filepath.SkipDir
}
return err
})
if err != nil && err != filepath.SkipDir {
// There is a .git, but we've encountered an error
return true, err
}
if !isEmpty {
return true, nil
}
}
// Since we know there's a .git directory, but there is nothing in it, we
// throw an error
return true, errors.NewEmptyGitRepositoryError(dir)
