Files added to the index don't influence getStatus

[sebastianrath]

After files got added to an index, getStatus doesn't regard them as it still returns them as "new".

Idea 1: Optionally pass an Index to getStatus to filter out these files

While WIP

test.only('test1', async (t) => {
  const repoPath = getRandomPath();
  const subdir = join(repoPath, 'subdir1', 'subdir2');

  const fileSample = 10;

  let repo: Repository;
  await Repository.initExt(repoPath)
    .then((repoResult: Repository) => {
      repo = repoResult;

      const addedFiles: string[] = [];
      const index = repo.ensureMainIndex();

      fse.ensureDirSync(subdir);
      t.log("Write 'subdir1/subdir2/foo' with 9 bytes");
      for (let i = 0; i < fileSample; ++i) {
        const relPath = join(subdir, `foo${i}`);
        addedFiles.push(relPath);
        fse.writeFileSync(relPath, i.toString());
      }

      index.addFiles(addedFiles);

      return index.writeFiles();
    }).then(() => {
      t.log('getStatus on all elements, including directories');
      return repo.getStatus(FILTER.ALL);
    }).then((statuses: StatusEntry[]) => {
      t.is(statuses.length, 0); // <-- the files were already written to the index, this should be 0
    });
});
