after checking that we can return commits in topological ordering, we should document that fact here

btw, you can verify this with ls -f

228–232

better type: rev SWHID → ancestor SWHIDs

better first description sentence: "The history cache map SWHIDs of type rev to a list of rev SWHIDs corresponding to all its revision ancestors, sorted in reverse topological order"

swh/fuse/tests/test_release.py
25

Comparing for set equality is correct, but will make these tests hard to maintain in the longrun.
It would be better to check that each expected element is among the listdir output (i.e., that is a subset).

Note that this is different from the case in which you are testing for the content of the virtual dir associated to a dir SWHID, because in that case any additional object is likely a bug. Here that is not necessarily the case.

This history field might be a bit redundant because get_history is already utilizing a sqlite cache and we probably want something more general in all __aiter__ (see T2695).
