clone: make sure we warm the cache after a clone
This work around any deviciency/limitation of the clone process. In our case
this ensure the persistent nodemap exist with valid content.
Ideally, the cloning process would also do "the right thing". However since
older server will never be able to do "the right thing". The local workaround
will be necessary anyway.
I am not worried by the performance impact of this as `hg clone` is non-instant
on large repositories where is could matters. Warming the cache if they are
already correct is very fast. And if they are not already warm, this seems like
a good time to do so.
This impact various test as more cache are now warmed sooner, all the change
should be harmless.
Differential Revision: https://phab.mercurial-scm.org/D9789
In this test, we want to test LFS bundle application on both LFS and non-LFS
repos.
To make it more interesting, the file revisions will contain hg filelog
metadata ('\1\n'). The bundle will have 1 file revision overlapping with the
destination repo.
# rev 1 2 3
# repo: yes yes no
# bundle: no (base) yes yes (deltabase: 2 if possible)
It is interesting because rev 2 could have been stored as LFS in the repo, and
non-LFS in the bundle; or vice-versa.
