is there a bug in urlunparse/urlunsplit

[Alex]

Hi all.

Is there a bug in the urlunparse/urlunsplit functions?
Look at this fragment (I know is quite silly):

urlunparse(urlparse('www.example.org','http'))
---'http:///www.example.org'
^^^^^

There are too many slashes, isn't it? Is it a known bug or maybe I
missed something...

Try these 3:

urlparse('www.example.org','http')
urlparse('http://www.example.org','http')
urlparse('//www.example.org','http')

The 1st returns www.example.org as the path part
with the other 2 its the location (domain) part.

Although it may not be immediately obvious that the result
is correct, consider the follwing html fragment:

<img src="aaa.gif">
<img stc="http://anothersite.com/bbb.gif">

If you were to use urlparse to parse the src attributes
you would want:

( '', '', 'aaa.gif', '','','' )
( 'http', 'anothersite.com', '/bbb.gif', '','','' )
Which AIUI is what urlparse does.

Hi Alex,
For a few years now I've been using Fourthought's libraries for parsing
URLs and they've performed beautifully. In the code comments, they state
that urlparse() and friends exhibit some non-RFCish behavior, hence the
inspiration for writing their own libraries.

If I remember correctly, the file you want is uri.py and it is in 4Suite
which you can download from here:
