A project P1 is under Git.
A project P2 is under Subversion.
P2 in fact replace a sub-directory (say SD) in P1. The project P2 is a
replacement (extension) of the code in P1.
How to deal with this?
If you clone P1, remove SD in P1 to replace it by P2:
$ git diff
-> will display all the changes in SD, is there a way to avoid that?
$ git merge (between branches) will try to merge changes in SD
I'd like to really tell Git to ignore SD as if it was not there. Any solution?
Thanks,
Pascal.

Remove SD in P1, make a logical link from P2 to SD, add SD to
.git/info/exclude
(see "Bug report - local (and git ignored) file silently removed after
checkout" on the mailing list why exclude is better than .gitignore at
the moment)

Thanks for your quick reply. That's what I have tested but...

Seems like this is working only if file names are different. This is not
my case as the replacement is very similar. With the following script
I'm expecting empty status and no diff:
<<
#!/bin/sh
# create sd (directory that will replace src2)
mkdir sd
echo sd1 > sd/file1
echo sd2 > sd/file2
# create Git repo
mkdir repo
cd repo
git init
mkdir src1
mkdir src2
echo file > src1/file
echo 3 > src2/file3
git add .
git ci -a -m "first"
# let's replace src2 by sd
rm -fr src2
# ln -s ../sd src2
cp -r ../sd src2
# make sure src2 is excluded
echo 'src2/*' >> .git/info/exclude
# the following output should be clean
echo '============== Status'
git status
echo '============== Diff'
git diff
>>
But the output is actually:
Initialized empty Git repository in /home/obry/tmp/repo/.git/
[master (root-commit) 527c7a1] first
2 files changed, 2 insertions(+), 0 deletions(-)
create mode 100644 src1/file

cp: cannot stat `../src': No such file or directory
============== Status

# Changes not staged for commit:
# (use "git add/rm <file>..." to update what will be committed)
# (use "git checkout -- <file>..." to discard changes in working

#

#
no changes added to commit (use "git add" and/or "git commit -a")
============== Diff
diff --git a/src2/file3 b/src2/file3
deleted file mode 100644

--- a/src2/file3

Any other idea?
Thanks.

You should also remove src2 and all files in it from the git repository.
Something like
git rm -r src2
git ci
echo 'src2' >> .git/info/exclude
instead of
rm -fr src2
echo 'src2/*' >> .git/info/exclude

Thanks this is working indeed. But it was not the whole story :)
In fact I want to do that in a branch (say work) and keep master as-is
as this branch is used to pull changes from origin. And in this case,
doing 'git diff master' still shows the files under src2. See script to
reproduce:
<<
#!/bin/sh
# create sd (directory that will replace src2)
mkdir sd
echo sd1 > sd/file1
echo sd2 > sd/file2
# create Git repo
mkdir repo
cd repo
git init
mkdir src1
mkdir src2
echo file > src1/file
echo 3 > src2/file3
git add .
git ci -a -m "first"
# let's replace src2 by sd in branch work
git checkout -b work
git rm src2/*
git ci -m "no more src2"
# ln -s ../sd src2
cp -r ../sd src2
# make sure src2 is excluded
echo 'src2' >> .git/info/exclude
# the following output should be clean
echo '============== Status'
git status
echo '============== Diff'
git diff
echo '============== Diff master'
git diff master
>>
Is that possible?

In my not-really-expert opinion no. At least git diff master has to show
something because there obviously is a difference between what is in
master (that you can't gitignore) and your branch (whether you ignore it
or not).
I would
a) use a different directory name for src2 and adapt the Makefile to
cope with that
or
b) remove the src2 link from .git/info/exclude and commit it into the
branch. That way whenever you switch branch and master, the correct dir
or link will be present and still because of the link none of the files
in the svn will be handled by git in any way

I had come to the same conclusion. Sad, it would have been nice to have
an option to fully ignore a path in a repository.
Anyway, thanks a lot for your feedback.
Pascal.

Don't look at it or encourage people to rely on that bug to be
fixed. exclude and .gitignore should behave the same way.
