破碎的Mercurial Repo

Question

我在我的根目录上执行了一个revursive sed，当我尝试提交hg，或者使用hg执行除hg --help之外的任何操作时，我得到了堆栈跟踪。当我执行sed时，我错误地认为.hg目录是写保护的。

存储库位于我的机器的本地。

有没有办法恢复我的changelog或提交评论？我在.hg目录中找到一个名为00changelog.i的文件，但它是一个无法执行的二进制文件。

sed命令：

find . -type f -exec sed -i.bak "s/sim-config.h/config.h/g" {} \;
find . -type f -exec sed -i.bak "s/av-config.h/config.h/g" {} \;

堆栈跟踪：

如果您没有可以替换.hg克隆的上游源，这可能取决于文件的混乱程度。然而，正如你注意到的，Mercurial在内部以二进制格式存储文件，这将使手动修复变得更加困难。

您可能没有使用sed -i.bak进行就地备份(这将使恢复变得容易)。

你可以这样做：

find .hg -mmin -60 -print

查看哪些文件在过去(比方说) 60分钟内被修改。也许修改的内容不多，您可以找到一些方法来逆转sed命令对该文件的影响(但如果您运行/foo/d之类的程序，这是不可能的)。

将来，在http://bitbucket.org/上注册一个免费帐户可能是值得的，它将为您提供免费的私人存储库托管和一个很好的备份位置。
