复制Git裸回购是否会更改日志? [英] Does copying the Git bare repo change the log?

问题描述

我想用git尝试一些事情，而且我不想在工作库中搞砸.

I'd like to try out a few things with git and I don't want to screw anything up in the working repository.

为了保持安全，我已经复制了我工作的裸仓库，并打算从此仓库进行所有推送和标记.我用过:

To try to keep things safe, I've made a copy of the bare repo that I work from and from this repo I am intending to do all my pushes and tagging. I used:

cp --preseve -r original.git copy_of_original.git

尽管我知道一个人可以撤消错误的提交，但我不想将所有这些还原的提交留给仓库，也不想进行任何重构，因此我希望只在一个重复的裸仓库中工作

Although I understand one can undo bad commits and whatnot, I don't want to leave the repo with all these reverted commits, nor do I want to do any refactoring, hence my desire to just work from a duplicate, bare repository.

问题是，我执行以下操作:

The problem is, I execute the following:

git diff --name-only master@{"5 day ago"} master

然后回来:

warning: Log for 'master' only goes back to Fri, 15 Feb 2013 20:42:43 -0500.

我不想接触的原始回购确实确实包含了5天前已修改的文件.

The original repo, which I don't want to touch, does indeed have files which were modified as of 5 days ago.

如果我对复制的仓库执行git log，则这5天的更改记录仍然存在.

If I perform git log on my copied repo, the record of these 5 day old changes are all still there.

这是怎么回事?

是否有更好的方法来制作存储库的独立副本?

Is there a better way to make an independent copy of the repository?

我意识到自己对这个问题不甚精确.我跑了:

I realized I was imprecise with my question. I had run:

git diff --name-only master@{"5 day ago"}

在以下位置产生的目录中:

in the directory produced from:

git clone copy_of_original.git clone_of_copy

推荐答案

@{5 days ago}语法依赖于 git-rev-parse的部分中进行了解释文档在下面引用. Reflog对存储库而言是本地的，从不通过克隆，获取或 推.这不是git log显示的信息，除非-g或 使用--walk-reflogs选项.

The @{5 days ago} syntax relies on information from the reflog, as explained in the section of the git-rev-parse documentation quoted below. Reflogs are local to a repository, and never transferred by clone, fetch or push. This is not the information displayed by git log, unless the -g or --walk-reflogs option is used.

裸仓库通常不保留reflog，因此仓库的副本 也不会有该信息.

Bare repositories generally don't keep reflogs, so a copy of the repository wouldn't have that information either.

<refname>@{<date>}, e.g. master@{yesterday}, HEAD@{5 minutes ago}
    A ref followed by the suffix @ with a date specification enclosed in a brace pair
    (e.g.  {yesterday}, {1 month 2 weeks 3 days 1 hour 1 second ago} or {1979-02-26
    18:30:00}) specifies the value of the ref at a prior point in time. This suffix may
    only be used immediately following a ref name and the ref must have an existing log
    ($GIT_DIR/logs/<ref>). Note that this looks up the state of your local ref at a
    given time; e.g., what was in your local master branch last week. If you want to
    look at commits made during certain times, see --since and --until.
