+# TODO before getting `persistent-nodemap` out of experimental
+#
+# * code/tests around aborted transaction
+# * code/tests around pending data for hooks
+# * code/tests around detection of invalid cache
+# (eg: after strip from an incompatible client)
+# * regenerate a new nodemap when the unused/total ration is to high
+# * decide for a "status" of the persistent nodemap and associated location
+# - part of the store next the revlog itself (new requirements)
+# - part of the cache directory
+# - part of an `index` directory
+# (https://www.mercurial-scm.org/wiki/ComputedIndexPlan)
+# * do we want to use this for more than just changelog? if so we need:
+# - simpler "pending" logic for them
+# - double check the memory story (we dont want to keep all revlog in memory)
+# - think about the naming scheme if we are in "cache"
+# * increment the version format to "1" and freeze it.
