context: generate filtered manifest efficiently for exact matchers When the matcher is exact, there's no reason to iterate over the entire manifest. It's much more efficient to iterate over the list of files instead. For a repository with approximately 300,000 files, this speeds up hg log -l10 --patch --follow for a frequently modified file from 16.5 seconds to 10.5 seconds.

    f.write('foo\n')

print '% add and commit'
add(u, repo, 'test.py')
commit(u, repo, message='*')
status(u, repo, clean=True)


print '% change'
f = open('test.py', 'w')
try:
    f.write('bar\n')
finally:
    f.close()

# this would return clean instead of changed before the fix
status(u, repo, clean=True, modified=True)
