files: speed up `hg files` when no flags change display
It's not the first time I see slowness from this command slow down
tools built on top of hg.
The majority of the time is spent merely printing the result before
this change, which is clearly not how it should be (especially since
the computation of the result also looks slow).
Running `hg files` in mozilla-central:
parent revision: 1,260s
this commit: 0,683s
this commit without batching ui.write: 0,931s
this commit replacing the body of the loop with `pass`: 0,566s
This looks like a prime candidate for a rust fast path, but until
then, it seems reasonable to optimize the python.

#require no-windows $ . "$TESTDIR/remotefilelog-library.sh" Set up an extension to make sure remotefilelog clientsetup() runs unconditionally even if we have never used a local shallow repo. This mimics behavior when using remotefilelog with chg. clientsetup() can be triggered due to a shallow repo, and then the code can later interact with non-shallow repositories. $ cat > setupremotefilelog.py << EOF > from mercurial import extensions > def extsetup(ui): > remotefilelog = extensions.find(b'remotefilelog') > remotefilelog.onetimeclientsetup(ui) > EOF Set up the master repository to pull from. $ hg init master $ cd master $ cat >> .hg/hgrc <<EOF > [remotefilelog] > server=True > EOF $ echo x > x $ hg commit -qAm x $ cd .. $ hg clone ssh://user@dummy/master child -q We should see the remotefilelog capability here, which advertises that the server supports our custom getfiles method. $ cd master $ echo 'hello' | hg -R . serve --stdio | grep capa | identifyrflcaps exp-remotefilelog-ssh-getfiles-1 x_rfl_getfile x_rfl_getflogheads $ echo 'capabilities' | hg -R . serve --stdio | identifyrflcaps ; echo exp-remotefilelog-ssh-getfiles-1 x_rfl_getfile x_rfl_getflogheads Pull to the child repository. Use our custom setupremotefilelog extension to ensure that remotefilelog.onetimeclientsetup() gets triggered. (Without using chg it normally would not be run in this case since the local repository is not shallow.) $ echo y > y $ hg commit -qAm y $ cd ../child $ hg pull --config extensions.setuprfl=$TESTTMP/setupremotefilelog.py pulling from ssh://user@dummy/master searching for changes adding changesets adding manifests adding file changes added 1 changesets with 1 changes to 1 files new changesets d34c38483be9 (run 'hg update' to get a working copy) $ hg up 1 files updated, 0 files merged, 0 files removed, 0 files unresolved $ cat y y Test that bundle works in a non-remotefilelog repo w/ remotefilelog loaded $ echo y >> y $ hg commit -qAm "modify y" $ hg bundle --base ".^" --rev . mybundle.hg --config extensions.setuprfl=$TESTTMP/setupremotefilelog.py 1 changesets found $ cd ..
