[Kde-scm-interest] Braindump: fixups

[Thiago Macieira]

This is a braindump. I don't expect anyone to follow my train of thought. 
I don't feel like making any changes to svn-all-fast-export any time 
soon. But, if somehow motivation strikes me in the future, this is 
information for me.

1) rename repositories to end in .git
  -> would allow things like KDE/kdebase.git and 
KDE/kdebase/workspace/libs/libplasma.git to exist at the same time

2) make svn-all-fast-export include some fixup information in the commit 
message:
 -> svn:externals detected (pathname found, path component, target, pegged 
version)
 -> if no pegged version, record the current revision
 -> copy-with-history detected from outside the current module (source, 
revision, target)

3) write a tool to create a revision map

4) modify svn-all-fast-export to detect when a subdirectory inside a 
module is another repository (libplasma)
 -> make it treat that like as if an svn:externals existed
    - i.e., write the extra information like above

5) write a tool that parses all commit messages in all branches in each 
repository, fixing svn:externals into git submodules
 -> remove the fixup information from the log
    - CHANGES ALL SHA-1 → requires recreating the revmap
 -> find the matching SHA-1 of the target repository
 -> add the tree entry for the submodule

6) write a tool that parses commit messages fixing the external 
copy-with-history
 -> extract the affected directory from the source repo
 -> create renaming commit
 -> add that commit as parent to the commit with the copy
 -> must not let this tool execute on the CVS branches imported since 
cvs2svn did a lousy job.
