title: I cannot find some of my commits in git log, but I can see it using git show, why?
body: <p>I cannot find some of my commits in <code>git log</code>, but I can see it using <code>git show the-SHA1-of-commit</code>, or in <strong>reflog</strong>. I appreciate if someone know how to retrieve these commits. My team made our own git server using gitblit, and there're some commits like <strong>"merge branch 'master' of <a href="http://example.com" rel="nofollow noreferrer">http://example.com</a>..."</strong></p>
