largefiles: don't warn when reverting a forgotten largefile Previously, when a largefile is forgotten and then reverted, a warning was issued: $ hg revert -R subrepo subrepo/large.txt file not managed: subrepo/large.txt (glob) This was purely cosmetic as the file itself actually was reverted. The problem was even with all of the matcher patching, the largefile pattern given on the command line wasn't converted to a standin because the standin was neither in ctx nor wctx. This causes the named largefile to be added to the 'names' dict in cmdutil.revert() in the repo walk at line 2550. The warning was printed out when the 'names' dict is iterated, because the file was specified exactly. Since core revert recurses into subrepos and largefiles only overrides the revert method in commands.py, it doesn't work properly when reverting a subrepo. However, it still will recurse into the subrepo and call the installed matcher method, so lfdirstate is reopened for the current repo level to prevent any new problems.

"""test behavior of propertycache and unfiltered propertycache

The repoview overlay is quite complex. We test the behavior of
property cache of both localrepo and repoview to prevent
regression."""
