[Python-Dev] test_inspect failure (original) (raw)

OK, it's down to this:

f = open('../lib/test/regrtest.py', 'rU') len(f.readlines()) 232 g = open('../lib/test/regrtest.py') len(g.readlines()) 715

IOW, opening in U mode screws up on Windows when universal newlines is enabled. This screws test_inspect.py for reasons so complicated I won't even try to trace the trail here; the bottom line is that lincache.py's updatecache() uses U mode near the end:

    fp = open(fullname, 'rU')
    lines = fp.readlines()
    fp.close()

For whatever reason, this only delivers the first 232 lines of regrtest.py. I doubt it's a coincidence this is darned near exactly the first 8192 bytes of the file.
