streamclone: force @filecache properties to be reloaded from file
Before this patch, consumev1() invokes repo.invalidate() after closing
transaction, to force @filecache properties to be reloaded from files
at next access, because streamclone writes data into files directly.
But this doesn't work as expected in the case below:
1. at closing transaction, repo._refreshfilecachestats() refreshes
file stat of each @filecache properties with streamclone-ed files
This means that in-memory properties are treated as valid.
2. but streamclone doesn't changes in-memory properties
This means that in-memory properties are actually invalid.
3. repo.invalidate() just forces to examine file stat of @filecache
properties at the first access after it
Such examination should concludes that reloading from file isn't
needed, because file stat was already refreshed at (1).
Therefore, invalid in-memory cached properties (2) are
unintentionally treated as valid (1).
This patch invokes repo.invalidate() with clearfilecache=True, to
force @filecache properties to be reloaded from file at next access.
BTW, it is accidental that repo.invalidate() without
clearfilecache=True in streamclone case seems to work as expected
before this patch.
If transaction is started via "filtered repo" object,
repo._refreshfilecachestats() tries to refresh file stat of each
@filecache properties on "filtered repo" object, even though all of
them are stored into "unfiltered repo" object.
In this case, repo._refreshfilecachestats() does nothing
unintentionally, but this unexpected behavior causes reloading
@filecache properties after repo.invalidate().
This is reason why this patch should be applied before making
_refreshfilecachestats() correctly refresh file stat of @filecache
properties.
