git-p4将perforce“main”分支迁移到git分支作为子目录(git分支中的双重代码)

2024年1月16日 367次阅读

情况

试图将1“主”和2个分支从perforce迁移到git.在使用specs映射perforce中的分支后,我尝试了典型的迁移,导致代码目录重复问题.

问题

运行“git p4”(克隆或同步)时,分支包含主分支代码的副本,分支代码位于主服务器旁边的目录中.我希望只能看到git staging区域中的分支代码.

#Perforce Repo Structure
//depot/main/branches/MAINT_01
//depot/main/branches/MAINT_02
//depot/main/branches/mobile

# perforce branch maps
# note: mobile and MAINT_02 are branched (in perforce) from MAINT_01
MAINT_02 -> //depot/main/branches/MAINT_01/... //depot/main/branches/MAINT_02/...
mobile  -> //depot/main/branches/MAINT_01/... //depot/main/branches/mobile/...

迁移尝试

这是怎么回事……

结果

agvscm01.inq.com /git/buildmaster/git2 304  % git checkout mobile
Checking out files: 100% (15073/15073), done.
Switched to branch 'mobile'
agvscm01.inq.com /git/buildmaster/git2 305  % ls
MAINT_01  mobile
agvscm01.inq.com /git/buildmaster/git2 306  %

请注意,MAINT_01和移动目录具有所有正确的历史记录,但只应在此级别上看到移动设备的内容.

期望

移动分支分支不应包含MAINT_01目录. mobile是MAINT_01的一个分支.这可能是非常简单的事情,但我没有看到它.
另外,签出master只包含MAINT_01作为root. MAINT_01的内容应该是分支的根.

agvscm01.inq.com /git/buildmaster/git2_bak 307  % git checkout master
Switched to branch 'master'
agvscm01.inq.com /git/buildmaster/git2_bak 308  % ls
MAINT_01
agvscm01.inq.com /git/buildmaster/git2_bak 309  %

感谢这里的任何帮助.

最佳答案 git-p4模块中的git有一个确认的错误,当使用–use-client-spec和–detect-branches选项时,将perforce代码错误地映射到git repo.我向Git开发团队报告问题时的电子邮件回复片段…

Thank you for the detailed report. It is a bug in 1.7.12-rc2.
This series fixes it, on top of origin/master.

The crux of the matter is that files are mapped into the wrong
locations in git when both –use-client-spec and –branch-detection
are enabled.

Pete Wyckoff (5):

  • git p4 test: move client_view() function to library
  • git p4 test: add broken –use-client-spec –detect-branches tests
  • git p4: set self.branchPrefixes in initialization
  • git p4: do wildcard decoding in stripRepoPath
  • git p4: make branch detection work with –use-client-spec
