A script to generate nasty diff worst-case scenarios:

     4

     5

  $ cat > s.py <<EOF

     6

  > import random

     7

  > for x in range(100000):

     8

  >     print

     9

  >     if random.randint(0, 100) >= 50:

    10

  >         x += 1

    11

  >     print(hex(x))

  > EOF

  $ hg init a

    15

  $ cd a

    16

    17

Check in a big file:

    18

    19

  $ "$PYTHON" ../s.py > a

    20

  $ hg ci -qAm0

    21

    22

Modify it:

    23

    24

  $ "$PYTHON" ../s.py > a

    25

    26

Time a check-in, should never take more than 10 seconds user time:

    27

    28

  $ hg ci --time -m1 --config worker.enabled=no

    29

  time: real .* secs .user [0-9][.].* sys .* (re)
