将所有Perforce分支导入Git仓库时出现问题

7
我正在尝试将公司Perforce仓库中的项目导入到git存储库中。我已经成功地将单个分支导入到单个git存储库中,但我想要做的是拉取整个项目以及所有分支,但我无法正确地使其工作。
我有我的.p4settings文件:
P4PORT=perforce-server.local:1666
P4USER=my.username
P4CLIENT=my.clientspec.name

Clientspec相当简单:

//project/... //my.clientspec.name/project/...
-//project/External/... //my.clientspec.name/project/External/...

今日免费次数已满, 请开通会员/明日再来
git p4 clone --verbose --detect-branches --max-changes=100 //project/...@all

这个过程会检查所有分支名称等,并尝试从第一个提交开始导入(该项目从变更列表771开始)。

Importing from //project/...@all into project
Initialized empty Git repository in /Users/grant/Development/git_test/project/.git/
Reading pipe: git config git-p4.useclientspec
Reading pipe: git config git-p4.user
Reading pipe: git config git-p4.password
Reading pipe: git config git-p4.port
Reading pipe: git config git-p4.host
Reading pipe: git config git-p4.client
p4 -G branches
Opening pipe: p4 -G branches
p4 -G branch -o branch-1
Opening pipe: p4 -G branch -o branch-1
Reading pipe: git config --bool core.ignorecase
p4 -G branch -o branch-2
...
Opening pipe: p4 -G branch -o branch-n
p4-git branches: []
initial parents: {}

我不确定p4-git分支以及初始父节点是否应该为空,但它们是空的。

最后,我们到了将更改列表导入git的时候,会出现以下情况:

Getting p4 changes for //project/...
p4 changes //project/...
Reading pipe: p4 changes //project/...
p4 -G describe 771
Opening pipe: p4 -G describe 771

现在,作为一个Perforce的新手,我不知道这意味着什么,也不知道如何解决这个问题,或者是否可能解决。有人遇到过类似的问题吗?如果是,你是如何解决的?

我终于找到了解决这个问题的方法。原来是Perforce分支映射被反向处理,这就是问题的根源。
Branch-foo是从MAIN分支创建的,应该拥有以下分支映射:
//project/MAIN/... //project/Branch-foo/...

然而,创建该分支的人将映射反转,因此结果如下:
//project/Branch-foo/... //project/MAIN/...

这个问题让git-p4感到困惑,因为MAIN的第一个更改清单是从#771开始的,而Branch-foo的更改清单是从#7652开始的,因此它无法在Branch-foo中找到任何父级并崩溃了。将分支规格更改为上面列出的第一个解决了这个问题。
