Subject: Test: Add a test that validates that empty streams are valid
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=fdf80f327cd463eacb1d8a209091733b0cea2073;p=deliverable%2Fbabeltrace.git

Test: Add a test that validates that empty streams are valid

Empty streams should be backed by a file of size 0 and be readable
by a CTF reader. This test validates that the problem described in
28362f2b is fixed.
