run-tests: install data files correctly
In 68964567e406 we began installing some data files in PREFIX/share.
When preparing to run the tests, run-tests.py uses --home="" in order
to work around home being set in a ~/.pydistutils.cfg file. This
somehow overwrites the --prefix option.
The result was that the share/ directory was installed in the top of
the Mercurial source tree.
#!/bin/sh
# In the merge below, the file "foo" has the same contents in both
# parents, but if we look at the file-level history, we'll notice that
# the version in p1 is an ancestor of the version in p2. This test
# makes sure that we'll use the version from p2 in the manifest of the
# merge revision.
hg init repo
cd repo
echo foo > foo
hg ci -qAm 'add foo'
echo bar >> foo
hg ci -m 'change foo'
hg backout -r tip -m 'backout changed foo'
hg up -C 0
touch bar
hg ci -qAm 'add bar'
hg merge --debug
hg debugstate | grep foo
hg st -A foo
hg ci -m 'merge'
hg manifest --debug | grep foo
hg debugindex .hg/store/data/foo.i
