[issue1462525] URI parsing library

[vincent kraeutler]

vincent kraeutler added the comment:

Quite like urlparse, uriparse does not fail on input which does not
represent valid URI's. At least not early or reliably enough.
Specifically, I noticed that urisplit does not fail on input strings
with a missing scheme, such as "foo.com/bar". 

I see no (straightforward) solution to this problem, short of using a
proper parser library such as Haskell's Parsec (I unfortunately know of
no Python equivalent), but I thought I might want to report this issue
nevertheless. 

The following might work as a quick-fix: Replace
regex.match(foo,bar).groups()

with something like:

    mm = re.match(regex, uri)
    sp = mm.span()
    if (-1 in sp) or (sp[1] - sp[0] != len(uri)):
        raise ValueError, "uri regex did not match complete input"
    
    p = mm.groups()
