 Create source repo, and commit adding largefile.

 Discard all cached largefiles in USERCACHE
 
   $ rm -rf ${USERCACHE}
 
 Create mirror repo, and pull from source without largefile:
 "pull" is used instead of "clone" for suppression of (1) updating to
 tip (= caching largefile from source repo), and (2) recording source
 repo as "default" path in .hg/hgrc.

 Update working directory to "tip", which requires largefile("large"),
 but there is no cache file for it.  So, hg must treat it as
 "missing"(!) file.
 
   $ hg update -r0

 Portable way to print file permissions:
 
   $ cat > ls-l.py <<EOF
   > #!$PYTHON
-  > import sys, os
+  > from __future__ import absolute_import, print_function
+  > import os
+  > import sys
   > path = sys.argv[1]
-  > print('%03o' % (os.lstat(path).st_mode & 0777))
+  > print('%03o' % (os.lstat(path).st_mode & 0o777))
   > EOF
   $ chmod +x ls-l.py
 
 Test that files in .hg/largefiles inherit mode from .hg/store, not
 from file in working copy:
 
   $ cd src
   $ chmod 750 .hg/store
   $ chmod 660 large
   $ echo change >> large
   $ hg commit -m change
   created new head
   $ ../ls-l.py .hg/largefiles/e151b474069de4ca6898f67ce2f2a7263adf8fea
   640
 
 Test permission of with files in .hg/largefiles created by update:
 
   $ cd ../mirror
   $ rm -r "$USERCACHE" .hg/largefiles # avoid links
   $ chmod 750 .hg/store
   $ hg pull ../src --update -q
   $ ../ls-l.py .hg/largefiles/e151b474069de4ca6898f67ce2f2a7263adf8fea
   640
 
 Test permission of files created by push:
 
   $ hg serve -R ../src -d -p $HGPORT --pid-file hg.pid \

   $ cat hg.pid >> $DAEMON_PIDS
 
   $ echo change >> large
   $ hg commit -m change
 
   $ rm -r "$USERCACHE"
 
   $ hg push -q http://localhost:$HGPORT/
 
   $ ../ls-l.py ../src/.hg/largefiles/b734e14a0971e370408ab9bce8d56d8485e368a9

 Test issue 4053 (remove --after on a deleted, uncommitted file shouldn't say
 it is missing, but a remove on a nonexistent unknown file still should.  Same

 Only dirstate is in the local store for the share, and the largefile is in the
 share source's local store.  Avoid the extra largefiles added in the unix
 conditional above.
