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.
