So:
~/darktable$ git describe
release-2.3.0-150-gec88795ce
$ git submodule status
8c0a57825a6e209b109ac18f8ba6966b36c596eb src/external/rawspeed (heads/develop)
~/darktable$ ls -lah src/external/rawspeed/CMakeLists.txt
-rw-r--r-- 1 lebedevri lebedevri 1.9K Jan 4 20:57
src/external/rawspeed/CMakeLists.txt
We are with working git master, with working submodule.
~/darktable$ git checkout darktable-2.2.x
error: The following untracked working tree files would be overwritten
by checkout:
bla bla bla
Please move or remove them before you switch branches.
Aborting
git does want us to accidentally loose data, so it warns us.
Since we know that it is expected, we have two ways:
WAY ONE:
~/darktable$ git checkout darktable-2.2.x -f
warning: unable to rmdir src/external/rawspeed: Directory not empty
Switched to branch 'darktable-2.2.x'
Your branch is up-to-date with 'upstream/darktable-2.2.x'.
~/darktable$ git describe
release-2.2.1-3-g4596f0b5d
~/darktable$ ls -lah src/external/rawspeed/CMakeLists.txt
-rw-r--r-- 1 lebedevri lebedevri 4.7K Jan 4 20:58
src/external/rawspeed/CMakeLists.txt
We are with working git stable branch.
Let's get back to master:
~/darktable$ git checkout master
M src/external/rawspeed
Switched to branch 'master'
Your branch is up-to-date with 'origin/master'.
~/darktable$ git describe
release-2.3.0-150-gec88795ce
~/darktable$ git submodule status
8c0a57825a6e209b109ac18f8ba6966b36c596eb src/external/rawspeed (heads/develop)
~/darktable$ ls -lah src/external/rawspeed/CMakeLists.txt
ls: cannot access 'src/external/rawspeed/CMakeLists.txt': No such file
or directory
Oops, git did not auto-handle the submodule, let's do that manually
~/darktable$ git submodule update
~/darktable$ git submodule status
8c0a57825a6e209b109ac18f8ba6966b36c596eb src/external/rawspeed (heads/develop)
~/darktable$ ls -lah src/external/rawspeed/CMakeLists.txt
ls: cannot access 'src/external/rawspeed/CMakeLists.txt': No such file
or directory
Let's re-try with -f
~/darktable$ git submodule update -f
Submodule path 'src/external/rawspeed': checked out
'8c0a57825a6e209b109ac18f8ba6966b36c596eb'
~/darktable$ git submodule status
8c0a57825a6e209b109ac18f8ba6966b36c596eb src/external/rawspeed (heads/develop)
~/darktable$ ls -lah src/external/rawspeed/CMakeLists.txt
-rw-r--r-- 1 lebedevri lebedevri 1.9K Jan 4 20:59
src/external/rawspeed/CMakeLists.txt
~/darktable$
And we're back to git master!
Summary: so even with normal operations, -f is needed...
WAY TWO:
~/darktable$ rm -rf src/external/rawspeed
~/darktable$ git checkout darktable-2.2.x
Switched to branch 'darktable-2.2.x'
Your branch is up-to-date with 'upstream/darktable-2.2.x'.
~/darktable$ git describe
release-2.2.1-3-g4596f0b5d
~/darktable$ git submodule status
~/darktable$ ls -lah src/external/rawspeed/CMakeLists.txt
-rw-r--r-- 1 lebedevri lebedevri 4.7K Jan 4 21:02
src/external/rawspeed/CMakeLists.txt
We are with working git stable branch.
Let's get back to master:
~/darktable$ git checkout master
Switched to branch 'master'
Your branch is up-to-date with 'origin/master'.
~/darktable$ git describe
release-2.3.0-150-gec88795ce
~/darktable$ git submodule status
-8c0a57825a6e209b109ac18f8ba6966b36c596eb src/external/rawspeed
~/darktable$ ls -lah src/external/rawspeed/CMakeLists.txt
ls: cannot access 'src/external/rawspeed/CMakeLists.txt': No such file
or directory
~/darktable$ git submodule update
Cloning into '/home/lebedevri/darktable/src/external/rawspeed'...
Submodule path 'src/external/rawspeed': checked out
'8c0a57825a6e209b109ac18f8ba6966b36c596eb'
So it will need to re-clone rawspeed.
Note: git submodule update takes --reference= parameter,
you may want to pass --reference ~/darktable/.git/modules/src/external/rawspeed/
which is where git put the submodule repo by default
~/darktable$ git submodule status
8c0a57825a6e209b109ac18f8ba6966b36c596eb src/external/rawspeed (heads/develop)
~/darktable$ ls -lah src/external/rawspeed/CMakeLists.txt
-rw-r--r-- 1 lebedevri lebedevri 1.9K Jan 4 21:03
src/external/rawspeed/CMakeLists.txt
~/darktable$
And we're back to git master!
Summary: no -f, but it re-clones the submodule.
TLDR: just use git checkout -f and git submodule update -f
