hook: move stdio redirection to context manager
The old code was checking stdio redirection in a loop.
This didn't make sense. The pattern is better expressed
as a context manager IMO, so this commit refactors it
to be one.

Checking the size/permissions/file-type of files stored in the dirstate after an update where the files are changed concurrently outside of hg's control. $ hg init repo $ cd repo $ echo a > a $ hg commit -qAm _ $ echo aa > a $ hg commit -m _ $ hg debugdirstate --no-dates n 644 3 (set |unset) a (re) $ cat >> $TESTTMP/dirstaterace.py << EOF > from mercurial import ( > extensions, > merge, > ) > def extsetup(ui): > extensions.wrapfunction(merge, 'applyupdates', wrap) > def wrap(orig, *args, **kwargs): > res = orig(*args, **kwargs) > with open("a", "w"): > pass # just truncate the file > return res > EOF Do an update where file 'a' is changed between hg writing it to disk and hg writing the dirstate. The dirstate is correct nonetheless, and so hg status correctly shows a as clean. $ hg up -r 0 --config extensions.race=$TESTTMP/dirstaterace.py 1 files updated, 0 files merged, 0 files removed, 0 files unresolved $ hg debugdirstate --no-dates n 644 2 (set |unset) a (re) $ echo a > a; hg status; hg diff
