Obnam version 1.0
Host: Gentoo amd64
When excluding a file that already exists on the backup, the file is not removed from the last backup, but it is kept, without being updated.
The file excluded should not appear on generations created with the exclude filter.
How to reproduce:
#############################################
#!/bin/sh
rm -rf /tmp/test
mkdir -p /tmp/test/backup
touch /tmp/test/backup/file1
touch /tmp/test/backup/file2
# 1st run, exclude file1
# only file2 is present on backup
obnam -r /tmp/test/repo --exclude=/tmp/test/backup/file1 backup /tmp/test/backup
obnam -r /tmp/test/repo ls
# 2nd run
# none excluded, both files present on backup
obnam -r /tmp/test/repo backup /tmp/test/backup
obnam -r /tmp/test/repo ls
# 3rd run, modify files and backup with exclude=file1
# both files present, file2 is updated on backup, file1 is neither updated, or removed
echo "000" > /tmp/test/backup/file1

A workaround can be found in http://listmaster.pepperfish.net/pipermail/obnam-flarn.net/2013-May/001929.html.
This is now fixed in git master. done --liw
