split up from #4292, as requested. Description there was:
Documentation cross-links are thoroughly messed up (the urls seem to be missing the package identifier): eg, the Bool in Data.List refer to libraries/Data-Bool.. instead of libraries/base-18.104.22.168%5CData-Bool..
To reproduce (in Opera 10.61):
- open Haskell hierarchical libraries HTML documentation (eg, via the startup menu group GHC)
- navigate to Data.List page
- scroll down to null entry
- click on Bool in type signature
- notice error message (file not found)
From looking at the directory structure, it is obvious that there should be a further indirection in the url, namely the package identifier:
Step 5 leaves Opera with this url
instead of the correct
On closer inspection, that id is present in the Data-List.html url, and the link to Data-Bool.html is relative, in the same package/directory.
Unfortunately, the Data-List.html url itself (from libraries/index.html), uses \ instead of the last /, which Opera encodes as %5C, which causes the relative link to Data-Bool.html to fail (missing package id, which would have been the last path component, which does not get recognized due to missing /).
Other browsers may behave differently, but my reading of rfc3986 is that \ does not separate hierarchical url components, hence there is no guarantee that relative links will work as used here (though, as so often, there is room for interpretation).
Replacing the %5C with a / and reloading Data-List.html is sufficient to make the links to Data-Bool.html et al work as expected, so the fix would be to get rid of spurious \s in hrefs in the docs, especially in libraries/index.html.
