test-bundle2-format: force gc so a GeneratorExit will be thrown
PyPy has looser semantics than CPython for when a generator's close
method will be called. Forcing the gc causes it to be called at
the right moment.
demandimport: add support for PyPy
PyPy's implementation of __import__ differs subtly from that of CPython.
If invoked without a name or fromlist, it throws an ImportError,
whereas CPython returns a reference to the level-appropriate importing
package.
Here, we achieve the same behaviour by hand.
test-demandimport: ensure that relative imports are deferred
This adds a test not just at our local "top level" (the mercurial
package), but also one level deeper (mercurial.hgweb).
histedit: don't bother with cPickle, demand-load pickle
We're unlikely to ever need the pickle module, so there's no good
reason to force loading of its faster cousin.
crecord: stop raising error.Abort if curses is not found (
issue5008)
On some servers, python curses support is disabled. This patch not only fixes
that but provides a fallback on other machines (e.g. Windows) when curses is
not found.
The previous code was actually flawed logic and relied on wcurses throwing an
ImportError which demandimport wouldn't throw. So, this patch also fixes that
problem.
cmdutil: use crecordmod.checkcurses
Instead of blindly trusting the user's experimental.crecord, we use checkcurses
to abstract that logic so that we can handle the case where python was not
built with curses.
