Eclipse egit：“检测到打包文件损坏：未知的zlib错误。”如何规避？

Question

We have a git repository managed by gitosis under Ubuntu, which has worked well all up to the disk ran full. After reading up a bit on the issue, I found that git gc and git gc --aggresive got me quite a bit of diskspace back. Very nice.

Unfortunately this appears to have broken something in egit, as I get this message when trying to clone our repository (during the checkout phase at around 10%)

Packfile corruption detected: Unknown zlib error.

Interestingly enough the git in msysgit works just fine as before.

I tried upgrading egit to the nightly build of 0.12 as there was some mailing list messages hinting this had been fixed within the last week, but to no avail.

My question now is, what can I do to my repository to get to a state where egit works again? I have full control over the Ubuntu instance running gitosis.

Answer 1

One way to get a clone without EGit is to:

• make a bundle on the server
• copy the unique file representing that bundle on the client side
• try to clone it in command-line.

Since you mention you can process the bundle with msysgit, that suggests a bug on the Egit or JGit side, as illustrated by bug 330758 .
The usual course of action is to update to the nightly latest fo EGit, using this p2 update site , and see if the problem is still there.
If the issue persists, you can then file a bug report or complete the existing one (330758).

Answer 2

请检查您正在运行的Git版本，并确保它们匹配。

Answer 3

The latest egit 0.12 does not show this behaviour.

Hopefully the bug has been fixed for real, and not just an accidental side effect.
