Oops.<br />&gt;<br />&gt;Damn, that's painful. I suspect I will have to change the format somehow.<br /><br />Having dodged that bullet with the change to make tree files point at<br />other tree files ... here's another (potential) issue.<br /><br />A changeset that touches just one file a few levels down from the top<br />of the tree (say arch/i386/kernel/setup.c) will make six new files in<br />the git repository (one for the changeset, four tree files, and a new<br />blob for the new version of the file). More complex changes make more<br />files ... but say the average is ten new files per changeset since most<br />changes touch few files. With 60,000 changesets in the current tree, we<br />will start out our git repository with about 600,000 files. Assuming<br />the first byte of the SHA1 hash is random, that means an average of 2343<br />files in each of the objects/xx directories. Give it a few more years at<br />the current pace, and we'll have over 10,000 files per directory. This<br />sounds like a lot to me ... but perhaps filesystems now handle large<br />directories enough better than they used to for this to not be a problem?<br /><br />Or maybe the files should be named objects/xx/yy/zzzzzzzzzzzzzzzz?<br /><br />-Tony<br />-<br />To unsubscribe from this list: send the line "unsubscribe linux-kernel" in<br />the body of a message to majordomo&#64;vger.kernel.org<br />More majordomo info at <a href="http://vger.kernel.org/majordomo-info.html">http://vger.kernel.org/majordomo-info.html</a><br />Please read the FAQ at <a href="http://www.tux.org/lkml/">http://www.tux.org/lkml/</a><br /><br /></pre></td><td width="32" rowspan="2" class="c" valign="top"><img src="/images/icornerr.gif" width="32" height="32" alt="\" /></td></tr><tr><td align="right" valign="bottom"> 聽 </td></tr><tr><td align="right" valign="bottom">聽</td><td class="c" valign="bottom" style="padding-bottom: 0px"><img src="/images/bcornerl.gif" width="32" height="32" alt="\" /></td><td class="c">聽</td><td class="c" valign="bottom" style="padding-bottom: 0px"><img src="/images/bcornerr.gif" width="32" height="32" alt="/" /></td></tr><tr><td align="right" valign="top" colspan="2"> 聽 </td><td class="lm">Last update: 2005-04-10 14:03 聽聽 [from the cache]<br />漏2003-2020 <a href="http://blog.jasper.es/"><span itemprop="editor">Jasper Spaans</span></a>|hosted at <a href="https://www.digitalocean.com/?refcode=9a8e99d24cf9">Digital Ocean</a> and my Meterkast|<a href="http://blog.jasper.es/categories.html#lkml-ref">Read the blog</a></td><td>聽</td></tr></table><script language="javascript" src="/js/styleswitcher.js" type="text/javascript"></script></body></html>
