[Pkg-bazaar-maint] Bug#493945: bzr rebase deletes not-checked-in files without warning

[Dwayne C. Litzenberger]

Package: bzr-rebase
Version: 0.3-1.1
Severity: important

"bzr rebase" just deleted my files before I had a chance to check them in.

Steps to reproduce:

* Initialize a new branch called "trunk" (or whatever; the branch names 
   don't matter.)

     ~$ mkdir trunk
     ~$ cd trunk
     ~/trunk$ bzr init
     ~/trunk$ echo 'Hello world' > hello.txt
     ~/trunk$ bzr add -q hello.txt
     ~/trunk$ ~/trunk$ bzr commit -q -m 'Add hello.txt'
     ~/trunk$ 

* Create a copy of "trunk" called "new-feature", and do some work in it, 
   including creating a directory and putting new files in it, checking in 
   some of the changes but not all of them.

     ~/trunk$ cd ..
     ~$ bzr branch -q trunk new-feature
     ~$ cd new-feature
     ~/new-feature$ mkdir foo
     ~/new-feature$ cd foo
     ~/new-feature/foo$ echo 'lots of work' > file1
     ~/new-feature/foo$ bzr add -q file1
     ~/new-feature/foo$ bzr commit -q -m 'Add file1'
     ~/new-feature/foo$ echo 'hours of work, almost done' > important-new-file
     ~/new-feature/foo$ 

* Switch back to "trunk" to make some changes that do not conflict with the 
   files in "new-feature".

     ~/new-feature/foo$ cd ../../trunk
     ~/trunk$ echo 'randomize ports' > security-fix
     ~/trunk$ bzr add -q security-fix
     ~/trunk$ bzr commit -q -m 'security fix'
     ~/trunk$ 

* Switch back to new-feature and rebase to bring in the security fix:

     ~/trunk$ cd ../new-feature
     ~/new-feature$ ls foo
     file1  important-new-file
     ~/new-feature$ bzr rebase ../trunk
     All changes applied successfully.
     Committing to: /home/dwon/new-feature/
     added foo
     added foo/file1
     Committed revision 3.
     ~/new-feature$ ls foo
     file1
     ~/new-feature$ 

Result:

1. "important-new-file" is gone without warning after bzr rebase.
2. user is unhappy
