Fix how setup.py identifies the Mercurial version.
There is a problem with setup.py where it will not identify the Mercurial
version properly when not being ran in within a repository even if
mercurial/__version__.py exists.
To fix, use mercurial.__version__.version when available before defaulting
to "unknown". (Using mercurial.util.version() is not an option due to a
dependency issue where osutil can be referenced before it is built.)
import os, sys
from mercurial import hg, ui
TESTDIR = os.environ["TESTDIR"]
# only makes sense to test on os which supports symlinks
if not hasattr(os, "symlink"):
sys.exit(80) # SKIPPED_STATUS defined in run-tests.py
# this is what symlink would do on a non-symlink file system
def symlink_failure(src, dst):
raise OSError, (1, "Operation not permitted")
os.symlink = symlink_failure
# now try cloning a repo which contains symlinks
u = ui.ui()
hg.clone(u, os.path.join(TESTDIR, 'test-no-symlinks.hg'), 'test1')
