## Create a directory in tempdir
path <- tempfile(pattern = "git2r-")
dir.create(path)

## Initialize a repository
repo <- init(path)
config(repo, user.name = "Alice", user.email = "alice@@example.org")

## Create a file, add and commit
writeLines("Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do",
           con = file.path(path, "test.txt"))
add(repo, "test.txt")
commit(repo, "Commit message 1")

## Change file and commit
writeLines(c("Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do",
             "eiusmod tempor incididunt ut labore et dolore magna aliqua."),
             con = file.path(path, "test.txt"))
add(repo, "test.txt")
commit(repo, "Commit message 2")

## Commit same content under different name in a sub-directory
dir.create(file.path(path, "sub-directory"))
file.copy(file.path(path, "test.txt"),
          file.path(path, "sub-directory", "copy.txt"))
add(repo, "sub-directory/copy.txt")
commit(repo, "Commit message 3")

## List blobs
b <- odb_blobs(repo)

## Order the data.frame before checking
b <- b[order(b$name), ]

## Check blobs
