git pull 对太长的文件名不起作用

Question

I did a commit (with Git) & push (to GitHub) 2 pdf files with a bit long names on my Windows 7 machine and then tried to pull those onto my Linux Mint machine, but got this error:

Updating 1453916..ffdfabc
error: cannot stat 'long-file-name-1.pdf': File name too long
error: cannot stat 'long-file-name-2.pdf': File name too long

How can I have those 2 files on my Linux Machine without losing the names and/or the files?

Answer 1

If you're NOT using encrypted home, as suggested by @phd, then you're most likely encountering a limitation of Linux that does not exist in Git.

Most Linux kernels are compiled with NAME_MAX=255 (see here ). Which means that file names cannot take more than 255 bytes. If you're using non-ASCII Unicode characters, than you have even less than 255 characters.

In Windows the limit is bigger than 255 bytes, which is why you're able to create these files in Windows.

If you want it to work on Linux, you need to rename them in Windows to something that is 255 bytes (bytes, not characters!) or less.

If you intend to check out those revisions, you'll need to do some history rewrite .

There are much crazier alternatives like re-compiling the kernel with a different NAME_MAX , don't go there if you don't absolutely have to.
