为什么git-svn应该积极寻找古老的历史？

Question

当我运行git svn clone -s时发生了一些奇怪的事情,虽然以下信息告诉我们不要惊慌,我想知道为什么这是svn错误？

为什么这条路不存在,是否会被其他人删除？

如果是的话,为什么git svn应该积极搜索旧历史？

Initializing parent: refs/remotes/tags/sequentialInformationalBottleneckClusterer-1.0.1@8400
W: Ignoring error from SVN, path probably does not exist: (160013): Filesystem has no item: File not found: revision 101, path '/trunk/packages/internal/sequentialInformationalBottleneckClusterer'
W: Do not be alarmed at the above message git-svn is just searching aggressively for old history.
This may take a while on large repositories
Checked through r1501

Answer 1

这是一个有趣的.不要惊慌.

在W:表示"警告",而这一切的警告告诉你的是,/trunk/packages/internal/sequentialInformationalBottleneckClusterer没有r0和R100之间的修订版本的SVN仓库.该警告于2008年初推出.

    git-svn: clarify the "Ignoring error from SVN" piece

    I've heard of several users puzzled by this, and it sometimes it
    appears as if git-svn is doing nothing on slower connections and
    larger repositories.

如果您有兴趣,可以在这里阅读原始主题.在此期间,只需忽略警告即可.有问题的子例程skip_unknown_revs(警告,如果github中的文件发生更改,此链接将会老化)如果遇到意外错误将终止进程.
