+Test operation on repository with an inlined changelog
+======================================================
+
+Inlined revlog has been a bag of complexity for a long time and the combination
+with special transaction logic on the changelog was a long source of bugs
+poorly covered by the test suites.
+
+We stopped doing any usage of inlined-revlog for changelog in a93e52f0b6ff,
+upgrading legacy inlined version as soon as possible when we see them. However
+this Mercurial does not produce such inlined-changelog that case is very poorly
+covered in the test suites. This test file aims at covering these cases.
+
+Double checking test data
+=========================
+
+We should have a repository around
+
+  $ mkdir sanity-check
+  $ cd sanity-check
+  $ tar xf $TESTDIR/bundles/inlined-changelog.tar
+  $ cd inlined-changelog
+  $ hg root
+  $TESTTMP/sanity-check/inlined-changelog
+
+The repository should not be corrupted initially
+
+  $ hg verify
+  checking changesets
+  checking manifests
+  crosschecking files in changesets and manifests
+  checking files
+  checking dirstate
+  checked 1 changesets with 1 changes to 1 files
+
+The changelog of that repository MUST be inlined
+
+  $ hg debugrevlog -c | grep -E '^flags\b'
+  flags  : inline
+
+Touching that repository MUST split that inlined changelog
+
+  $ hg branch foo --quiet
+  $ hg commit -m foo --quiet
+  $ hg debugrevlog -c | grep -E '^flags\b'
+  flags  : (none)
+
+  $ cd ../..
+
+Test doing a simple commit
+==========================
+
+Simple commit

+  $ hg verify
