在 git 中显示索引文件的权限 [英] Show the permission of a indexed file in git

问题描述

这与我最近问的关于将非裸存储库存储在Dropbox 用于在计算机之间轻松移动，因此阅读该问题的背景可能会有所帮助.

This is related to another question I recently asked about storing a non-bare repository in Dropbox for easy movement between computers, so it may be helpful to read that question for background.

要点是 fileMode 不断报告一些文件的差异.我找不到一种方法来始终如一地重现它，但它经常发生.我注意到的是，在两台机器上都有 644 权限的文件经常报告与其中一台机器上的 755 不同.这让我认为 Git 相信可执行位已设置，但我不知道我是否真的可以看到 Git 是如何设置该位的.

The gist is that the fileMode keeps reporting a diff for some number of files. I can't find a way to reproduce it consistently, but it happens frequently. What I've noticed is that the file, which has 644 permissions on both machines often reports a diff from 755 on one of the machines. This makes me think that Git believes the executable bit is set, but I can't figure out whether I can actually see how Git has that bit set.

推荐答案

要查看 git 实际上对提交和索引中的文件有何看法，请使用 git ls-tree 和 git ls-files -s 分别.

To see what git actually thinks about your files in commits and the index, use git ls-tree <tree> and git ls-files -s <path> respectively.

顺便说一下，git 似乎只查看可执行位，并假设 644 用于其他所有内容.查看 create_ce_mode in cache.h 如果你想尝试调试这个奇怪的问题.

By the way, it seems that git only looks at the executable bit, and assumes 644 for everything else. Look at create_ce_mode in cache.h if you want to try debugging this weird issue.
