anlambert requested review of this revision.Dec 14 2021, 5:57 PM

Gawd this is horrible! (not your fault!)

swh/loader/svn/utils.py
172	I don't understand the usage of 'absolute' in this docstring. Wouldn't it better to describe it as "according SVN external definitions" or so? I mean 'join("url://path/", "/toto")' giving "url://path/toto" does not make much sense to me (being used to urllib's behavior) but qulifying this as "absolute" does not make much sense, so "join url the SVN way" seems better to me :-)
222	why does't `external.split()` suffice for the job?
282	I see no test for this case (`url@toto`), what is the expected result there?

Yeah, I had a lot of fun writing this one but subversion externals specification can have so many forms.

swh/loader/svn/utils.py
172	Ack, I can rename it to `svn_urljoin`, this will be less confusing.
222	yeah right, it is enough to do so.
282	We can have some URLs like `http://anon:anon@svn.example.com/skin-maker` (it is in a test case), so that workaround.

Rebase and adapt according to @douardda reviews

lgtm

I got the feeling the more we will dig into those old vcs the more will get code like this in our loaders...
(I recall having read some similar parsing code for the cvs one).

I've changed the reviewers to blocking:reviewers so david has the last word on your good adaptations.

Note:
Sorry, it took me some time to actually reading through it (I started in december...).
