在Git中测量/计数对象以查看我是否接近自动包装 [英] Measure / count objects in Git to see whether I am close to auto-packing

问题描述

我想对git中的对象进行测量/计数以查看是否接近自动打包，我认为可以通过对.git/objects/...中的文件进行计数来完成此操作，但是我不确定.

I would like to measure / count objects in git to see whether I am close to auto-packing, I think it can be done trivially by counting files in .git/objects/..., but I am not sure.

这是故事:

几天以来，每当我推送到git repo时，它都会自动打包. (git仓库位于USB记忆棒上，因此自动打包速度非常慢，大约30分钟后我就取消了它)

For a couple of days now, my git repo is auto-packing itself whenever I push to it. (The git repo lives on a USB memory stick, therefore the auto-packing is awfully slow and I have cancel it after 30 minutes or so)

与以下问题相同:

自动打包用于最佳性能"是什么意思?

我的git仓库有问题.在过去的两天内，每当我推送到服务器时，我都会收到以下消息:自动打包存储库以获得最佳性能"

I'm having a problem with my git repo. For the last couple of days whenever I do a push to the server I get this message: "Auto packing the repository for optimum performance"

在同一线程中，我找到了解决方案:

In that same thread I found the solution:

要为一个项目禁用:

To disable for one project:

cd your_project_dir

cd your_project_dir

git config gc.auto 0

git config gc.auto 0

要全局禁用:

git config --global gc.auto 0

git config --global gc.auto 0

这解决了我针对该特定存储库的问题...

That solved my problem for that particular repo...

...但是我的记忆棒上还有更多的git repo，我想知道一种方法来衡量我的其他git repos是否接近自动打包

...but I have got many more git repo's on my memory stick and I would like to know a way to measure if any of my other git repos is close to auto-packing

我发现:

为什么git会自动运行每次回购时都要打包?

Git根据两个条件决定是否自动执行gc:

Git decides whether to auto gc based on two criteria:

包装太多吗? (从字面上看，.git/objects/pack中是否有超过50个带有.idx的文件?)

Are there too many packs? (Literally, are there more than 50 files with .idx in .git/objects/pack?)

是否有太多的松散物品? (从字面上看，.git/objects/17中是否有27个以上的文件?)

Are there too many loose objects? (Literally, are there more than 27 files in .git/objects/17?)

我的问题几乎可以回答，但我只是想确认自己已正确理解:如何测量/计算松散的物体以查看是否接近自动包装? -是否确实按照上述答案中的建议(如上述答案所示)对.git/objects/17中的文件进行计数并与硬限制27相比较，

My question is almost answered, but I would simply like to have confirmation that I understand correctly: How can I measure / count loose objects to see if I am close to auto-packing ? -- is it (as suggested in the above answer) literally counting files in .git/objects/17 and compare to the hard limit of 27,

-还是正在计数.git/objects/01，.../02，.../03等中的所有文件，并将平均值与git config global中定义的软限制进行比较?

-- or maybe it is counting all files in .git/objects/01, .../02, .../03, etc... and comparing the average to a soft limit defined in git config global ?

-即使琐碎，还是有一个git命令来计算.git/objects/17中的对象? -是否有git命令返回硬限制27?

-- even if it is trivial, is there a git command that counts objects in .git/objects/17 ? -- is there a git command that returns the hard limit of 27 ?

The answer at Why does git run auto-packing on every push to our repo? is still valid. As you can see in the source code of the latest release of git (2.10.2), this is the function need_to_gc that decides whether gc is run.

• 选项gc.auto是否设置为0或负数?
• 是否存在 too_many_packs :选项gc.autopacklimit(默认值为50)是否为正数且小于包数(.git/objects/pack中的*.idx个文件)?
• 是否存在 too_many_loose_objects :选项gc.auto(默认值为6700)为正数，并且是.git/objects/17中的松散对象的数量(仅在此目录中查找；不计算全部，并且取平均值或最大值或类似的值) )大于({gc.auto} + 255)/256)?

• Is the option gc.auto is set to 0 or negative?
• Are there too_many_packs: is the option gc.autopacklimit (default 50) positive and less than the number of packs (*.idx files in .git/objects/pack)?
• Are there too_many_loose_objects: is the option gc.auto (default 6700) positive, and is the number of loose objects in .git/objects/17 (it looks only in this directory; doesn't count all and take average or max or anything like that) greater than ({gc.auto} + 255)/256)?

所以这就是数字27的来源:它是(6700 + 255)/256的下限.您可以通过增加gc.auto来增加它.您可以使用git命令git config --get gc.auto获得与该数字27相等的值，但这仅在显式设置了该选项的情况下有效.

So that's where the number 27 comes from: it's the floor of (6700 + 255)/256. You can increase it by increasing gc.auto. You can get the equivalent of this number 27 with the git command git config --get gc.auto but that only works if the option has been explicitly set.
