tests: add test for Python 3 compatibility
Python 3 is inevitable. There have been incremental movements towards
converting the code base to be Python 3 compatible. Unfortunately, we
don't have any tests that look for Python 3 compatibility. This patch
changes that.
We introduce a check-py3-compat.py script whose role is to verify
Python 3 compatibility of the files passed in. We add a test that
calls this script with all .py files from the source checkout.
The script currently only verifies that absolute_import and
print_function are used. These are the low hanging fruits for Python
compatbility. Over time, we can include more checks, including
verifying we're able to load each Python file with Python 3. You
have to start somewhere.
Accepting this patch means that all new .py files must have
absolute_import and print_function (if "print" is used) to avoid
a new warning about Python 3 incompatibility. We've already
converted several files to use absolute_import and print_function
is in the same boat, so I don't think this is such a radical
proposition.

Check whether size of generaldelta revlog is not bigger than its regular equivalent. Test would fail if generaldelta was naive implementation of parentdelta: third manifest revision would be fully inserted due to big distance from its paren revision (zero). $ hg init repo --config format.generaldelta=no --config format.usegeneraldelta=no $ cd repo $ echo foo > foo $ echo bar > bar $ echo baz > baz $ hg commit -q -Am boo $ hg clone --pull . ../gdrepo -q --config format.generaldelta=yes $ for r in 1 2 3; do > echo $r > foo > hg commit -q -m $r > hg up -q -r 0 > hg pull . -q -r $r -R ../gdrepo > done $ cd .. >>> import os >>> regsize = os.stat("repo/.hg/store/00manifest.i").st_size >>> gdsize = os.stat("gdrepo/.hg/store/00manifest.i").st_size >>> if regsize < gdsize: ... print 'generaldata increased size of manifest' Verify rev reordering doesnt create invalid bundles (issue4462) This requires a commit tree that when pulled will reorder manifest revs such that the second manifest to create a file rev will be ordered before the first manifest to create that file rev. We also need to do a partial pull to ensure reordering happens. At the end we verify the linkrev points at the earliest commit. $ hg init server --config format.generaldelta=True $ cd server $ touch a $ hg commit -Aqm a $ echo x > x $ echo y > y $ hg commit -Aqm xy $ hg up -q '.^' $ echo x > x $ echo z > z $ hg commit -Aqm xz $ hg up -q 1 $ echo b > b $ hg commit -Aqm b $ hg merge -q 2 $ hg commit -Aqm merge $ echo c > c $ hg commit -Aqm c $ hg log -G -T '{rev} {shortest(node)} {desc}' @ 5 ebb8 c | o 4 baf7 merge |\ | o 3 a129 b | | o | 2 958c xz | | | o 1 f00c xy |/ o 0 3903 a $ cd .. $ hg init client --config format.generaldelta=false --config format.usegeneraldelta=false $ cd client $ hg pull -q ../server -r 4 $ hg debugindex x rev offset length base linkrev nodeid p1 p2 0 0 3 0 1 1406e7411862 000000000000 000000000000 $ cd ..
