提交 487128950df6ee433c131b5feaafe81ee86629f4 可以在 https://github.com/上找到signalwire/freeswitch.git .

git log -1 487128950df6ee433c131b5feaafe81ee86629f4 --pretty = fuller 打印:

    Use the system version of APR / APR-util if possible

    Autodetect whether the system libapr / libaprutil has our
    necessary modifications and use it if it does.

有2位作者.如果启用了fsck检查，则将此提交推送到Gitlab或Github可能会失败，并抱怨 remote:error:object 487128950df6ee433c131b5feaafe81ee86629f4:multipleAuthors:无效的格式-多行作者"行.

It has 2 authors. Pushing this commit to Gitlab or Github could fail if fsck check is on, complaining remote: error: object 487128950df6ee433c131b5feaafe81ee86629f4: multipleAuthors: invalid format - multiple 'author' lines.

我很好奇这个提交是如何创建的.记录多位作者的解决方案之一是在提交消息中附加 Co-authored by .由于可以由两个作者创建一个提交，为什么它不是内置方法呢?为何 git fsck 将此提交视为不良对象?

I'm curious how this commit was created. One of the solutions to record multiple authors is appending Co-authored-by in the commit message. As it's possible to create a commit with two authors, why hasn't it been a built-in method? And why is such a commit considered as a bad object by git fsck?

推荐答案

git提交对象是

A git commit object is just a compressed text file. This one happens to have two authors.

$ pigz -d < .git/objects/48/7128950df6ee433c131b5feaafe81ee86629f4 
commit 438tree 070633dfc3ea352dfb1094822f477111e519a9ca

Use the system version of APR / APR-util if possible

necessary modifications and use it if it does.

我很好奇如何创建此提交.

您必须向特拉维斯·克罗斯(Travis Cross)询问他们是如何做到的.进行提交是只不过是将文本写入文件

You'd have to ask Travis Cross for exactly how they did it. Making a commit is not much more than writing text to a file.

为什么git fsck会将此类提交视为不良对象?

在内部， Git每次提交只能有一位作者.允许多位作者需要对内部进行重新设计.

Internally, Git can only have one author per commit. Allowing multiple authors would require reworking the internals.

git-log 将显示多个作者，这可能是一个实现上的怪癖.其他工具将不尊重两位作者.例如， git shortlog --group = author 仅计算对Anthony Minessale的提交.

While git-log will display multiple authors that's probably an implementation quirk. Other tools will not honor both authors. For example, git shortlog --group=author only counts the commit to Anthony Minessale.

如果您需要多个作者，请添加共同作者通过拖车" .

If you need multiple authors, add co-authors via "trailers".
