+===================================
+Test repository filtering avoidance
+===================================
+
+This test file is a bit special as he does not check feature, but performance related internal code path.
+
+Right now, filtering a repository comes with a cost that might be significant.
+Until this get better, ther are various operation that try hard not to trigger
+a filtering computation. This test file make sure we don't reintroduce code that trigger the filtering for these operation:
+
+Setup
+-----
+  $ hg init test-repo
+  $ cd test-repo
+  $ echo "some line" > z
+  $ echo a > a
+  $ hg commit -Am a
+  adding a
+  adding z
+  $ echo "in a" >> z
+  $ echo b > b
+  $ hg commit -Am b
+  adding b
+  $ echo "file" >> z
+  $ echo c > c
+  $ hg commit -Am c
+  adding c
+  $ hg rm a
+  $ echo c1 > c
+  $ hg add c
+  c already tracked!
+  $ echo d > d
+  $ hg add d
+  $ rm b
+
+  $ cat << EOF >> $HGRCPATH

+  > [ui]
+  > debug = yes
