[Python-apps-team] Bug#623336: rdiff-backup: --max-file-size breaks --exclude instructions

[Zachary Palmer]

Package: rdiff-backup
Version: 1.2.8-6
Severity: normal


Running rdiff-backup with --max-file-size breaks the behavior of --exclude.
Excluded files are still included when --max-file-size is used.  For an example
of this behavior, execute the following (bash) commands:

	mkdir temp
	cd temp
	mkdir -p src src/{a,b}
	touch src/{a,b}/file
	rdiff-backup --include=src/a --exclude=src/* src good-backup
	rdiff-backup --max-file-size 104857600 --include=src/a --exclude=src/* src bad-backup

The first command creates the backup we would expect: it only includes the 'a'
directory and not the 'b' directory.  The second backup should therefore
behave the same; the only difference is the maximum file size of 100MB, which
we clearly have not exceeded.  Nonetheless, the bad-backup directory contains
a backup of directory 'b' as well.

This is of particular annoyance because backupninja relies on rdiff-backup's
include/exclude behavior in this way.  This makes it impossible to use
"options=--max-file-size 104857600" to exclude files over 100MB when using
rdiff-backup in a backupninja session.  This is not a problem with the
backupninja helper, though, as shown by the session above.
