可以使Mercurial保留文件权限吗? [英] Can Mercurial be made to preserve file permissions?

问题描述

我看过许多博客文章，并亲身体验到Mercurial不会保留从一个存储库推送到另一个存储库的文件的权限.有谁知道可以保留权限的Mercurial扩展?我假设它不能用钩子完成，因为钩子对原始存储库中的权限了解什么?

I've seen a number of blog posts, and have experienced for myself, that Mercurial does not preserve the permissions on files pushed from one repo to another. Does anyone know of a Mercurial extension that would preserve the permissions? I'm assuming it can't be done with a hook, because what does a hook know about permissions at the originating repo?

要求的详细说明:

• 如果对文件的唯一更改是权限的更改(例如，chmod o+r filename)，则尝试提交文件失败，并显示一条消息，指出文件未更改.

• If the only change to a file is a change in permissions (e.g., chmod o+r filename), attempts to commit the file fail with a message saying that the file has not changed.

如果我提交具有权限600(rw -------)的文件，然后克隆该存储库，则克隆中的同一文件具有权限664(rw-rw-r-):

If I commit a file with permissions 600 (rw-------), then clone the repo, the same file in the clone has permissions 664 (rw-rw-r--):

: nr@yorkie 6522 ; hg clone one two
updating working directory
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
: nr@yorkie 6523 ; ls -l one two
one:
total 4
-rw------- 1 nr nr 8 Aug 18 21:50 foo

two:
total 4
-rw-rw-r-- 1 nr nr 8 Aug 18 21:51 foo

此示例显示hg clone不会保留权限，但hg push也不也会保留权限.

This examples shows that hg clone does not preserve permissions, but hg push does not preserve them either.

在我的应用程序中，一个回购在一条可公开访问的路径上，这是最重要的

In my application, one repo is on a publically accessible path, and it's of major importance that

• 多个用户有权更改存储库

• Multiple users have the right to change the repo

仅在显式可读的情况下，公共仓库中的文件才可读.

Files in the public repo become readable only when explicitly made readable.

推荐答案

看起来可以使用钩子和辅助工具(还有一点口香糖和打包线)来完成:

It looks like it can be done using hooks and an auxiliary tool (and a little chewing gum and baling wire):

1. 获取David Hardeman的 Metastore ，该文件可以保存和恢复文件元数据.

1. Get David Hardeman's Metastore, which saves and restores file metadata.

更改源，因此它将忽略目录.hg和.git.

Alter the sources so it will ignore directory .hg as well as .git.

使用以下Mercurial挂钩:

Use the following Mercurial hooks:

 precommit.meta = metastore -s

 changegroup.update = hg update
 update.meta   = /usr/unsup/nr/bin/metastore -a

您必须将.metadata文件添加到存储库中.

You have to add the .metadata file to the repo.

此修改通常在大多数时间都有效，但是如果您仅更改 权限并希望传播该权限，则必须运行metastore -s才能将这些更改推送到.metadata中. hg将看到更改的文件；否则，提交者认为没有新内容.

This lashup will work most of the time, but if you change only permissions and want to propagate it, you'll have to run metastore -s in order to push those changes into the .metadata file where hg will see the change; otherwise the commit thinks nothing is new.
