absurls in wiki_to_html doesn't seem to take care of relative links

[ittayd@…]

i have a page with 'Page' link. using wiki_to_html(text, self.env, req, absurls=True) still leaves the href as '<a href="./SomeOtherPage?">'

Well, this should have worked in trunk, since the introduction of WikiContext and the related refactoring of relative links (r4442).

... but apparently it's broken for some reason, I'll check.

... and the reason was precisely that r4442 was not merged, damn ;)
Corrected in r4461.

my case was that i was trying to use wiki_to_html from one page in another. this means my 'req' contains the wrong href. is this solved with contexts?

[ittayd@…]

and why not use urlparse?

Replying to ittayd@qlusters.com:

Yes, that's the purpose of the Wiki contexts.

and why not use urlparse?

... and why use it? Sorry, but maybe you should be more explicit here.

The [./SomeOtherPage Page] link now work as advertised in trunk, AFAICT:
it will produce a link to a sub-page of the current page.
For a sibling page, you'd have to use [../SomeSiblingPage Next Page].

In addition, if the rendering context specifies abs_urls=True, then the generating links will be absolute ones.

[ittayd@…]

to elaborate:

• say i'm in page foo/bar/zoo, and i call wiki_to_html on A/B/C, then if it contains D, the url will be http:/.../wiki/A/B/D.
• urljoin provides the functionality of joining a base and relative url.

What you described was the 0.10 behavior, which tried to make the behavior of relative TracLinks similar to those of relative URLs.
I changed this semantic for 0.11 (as documented in r4442), because there was no way to take the current page into account, which is required for being able to create relative links to sub-pages. With URLs, you obviously don't have this issue, as anything which is not prefixed will be relative to the current page. Conversely, in the Wiki, non-prefixed links are still "absolute" ones, e.g. linking to TracBrowser from anywhere in the Wiki, however deep, still links to .../wiki/TracBrowser.

So, for relative TracLinks written in some content attached to page A/B/C, we have the following semantics:

TracLinks	0.10	0.11
.	A/B parent	A/B/C self
..	A/B/D grand-parent	A/B parent
./D	A/B/D sibling	A/B/C/D sub-page
../D	A/D uncle...	A/B/D sibling

Not to mention that without WikiContext (so in 0.10), you have no ways to specify links relative to page A/B/C when calling wiki_to_html in page foo/bar/zoo.

With 0.11, if ctx is set to be the context for wiki:foo/bar/zoo, then rendering A/B/C content with correct relative links is a matter of calling:

ctx('wiki', 'A/B/C').wiki_to_html(abc_content)
