</code></pre>
<p>After these four commits, the repository contains only one thing: a source file <code>src/pkg/debug/macho/testdata/hello.c</code>, which is a C Hello World program. The next commit is by Robert Griesemer in 2008.</p>
<p>Why did the Go creators start their work on top of some Hello World project by Kernighan? Why did he keep a Hello World project for sixteen years? If he did, how could anything he did to it be "last-minute"? How and why was this information imported into git? I have so many questions.</p>
<hr/>**评论：**<br/><br/>ifuporg: <pre><p>It is a cute joke. You can manipulate commit dates easily with <code>git commit --date "Tue Jul 18 19:05:45 1972" --author "BK <bwk>"</code></p></pre>stillalone: <pre><p>Damn, I wish I had known this several years ago. The company I work for ported a bunch of repos from svn to git. The guy who did the porting didn't bother with this and all the commits ended up having his name and the date he did the transfer.</p></pre>isxek: <pre><p>I'm no DVCS expert, but AFAIK, both Git and Mercurial have extensions that should have been able to handle that better. IIRC, Git has <code>git-svn</code> for this, and Mercurial has <code>hgsubversion</code> and the <code>convert</code> extensions.</p>
<p>I mentioned this because at one point I had played with both VCS's to convert the flagship repositories of a company I previously worked with from SVN to either Git or Hg.</p></pre>huitzitzilin: <pre><p>I've used git-svn before too and managed to keep the commit history tidy</p></pre>isxek: <pre><p>It's pretty handy not just for converting repositories - it can also be used as a Subversion client. (I think even Linus Torvalds mentioned people doing this as early as <a href="https://www.youtube.com/watch?v=4XpnKHJAok8" rel="nofollow">that Google talk about Git</a>.)</p></pre>scarhill: <pre><p>Another option for conversions is <a href="/u/esr" rel="nofollow">/u/esr</a>'s Reposurgeon: <a href="https://gitlab.com/esr/reposurgeon" rel="nofollow">https://gitlab.com/esr/reposurgeon</a></p></pre>Twirrim: <pre><p>WTF. There are even CLI utilities that do the migration for you, including full commit history.</p></pre>BeechM: <pre><p>It's not too late if you've got the old SVN repo and you're willing to get fast and loose with commit history.</p></pre>sh41: <pre><p>Get loose with it.</p></pre>SSoreil: <pre><p>Because that's the Lineage of Go, there have been some talks on this by (I think) Robert Griesemer. You should be able to find them on YouTube somewhere.</p></pre>sh41: <pre><blockquote>

<p>Note that two of the commits were done on April 1, so you just fell for an April Fool joke.</p></pre>s4n_rd: <pre><p>may be this indicate "go project started as a better c"
