* Ikiwiki can be configured to generate html5 instead of the default xhtml
1.0. The html5 output mode is experimental, not yet fully standards
compliant, and will be subject to rapid change.
Needed to handle the move of the .js files into ikiwiki/, but also this is
a longstanding bug.
Old pagemtime is not remembered in rebuild mode, and changing that would
need a lot of changes. So instead, loop on pagectime, which is remembered.
Change to remembering old pagesources info in rebuild mode. This seems safe
enough.
Rather than wasting resources recording that every page depends on
page.tmpl, add a special case. The special case curretly rebuilds non-page
files too when page.tmpl changes, but that's minor.
This entailed changing template_params; it no longer takes the template
filename as its first parameter.
Add template_depends to api and replace calls to template() with
template_depends() in appropriate places, where a dependency should be
added on the template.
Other plugins don't use template(), so will need further work.
Also, includes are disabled for security. Enabling includes only when using
templates from the templatedir would be nice, but would add a lot of
complexity to the implementation.
This is needed so that when a negated pagespec like "!author(foo)"
stops matching, due to the page being changed, ikiwiki knows that
the match was influenced by the page content.
The commit that added the (working) support for using /tag to override
tagbase also tried to make ./tag work. Problem is, tags are links,
and ./foo is not a valid link (though I think there's a wishlist about it).
So, using ./tag really resulted in tag creation links that led to a
"bad page name" error. And even if the tag were created in the right place,
the link didn't go to it.
loadindex does not bother populating oldtypedlinks if there is no link
type. However, the code in link_types_changed assumed that if oldtypedlinks
is not defined, and typedlinks is, they must differ.
This fixes the problem that it did not remember if an autofile is deleted,
unless a plugin happened to register the autofile at the same time.
With the new code, we just never recreate an autofile more than once.
Only downside is that the list of autofiles is never pruned either.
And I don't really see a way to prune it.
Splitting out this function bothered me. It is conceptially similar to
file_pruned, and yet also very specific to exactly the security needs of
find_src_files.
I liked that it got rid of duplicate code in the latter function. So
instead, put a helper sub in that, which I think allows refactoring
things more cleanly, and with less boilerplate.
As to the needs of gen_autofile, I'm not convinced this needs to handle
the same set of problems that verify_src_file did. So I sat down and
wrote a custom validator for autofiles, which turned out to seem to just
need three things: Make sure the candidate filename is not something
that would be pruned; untaint the candidate filename; and make sure that
srcdir doesn't already have something with its name. (Plus, of course,
all the other checks that were already in gen_autofile.)
(In passing, also fixed a bunch of bugs I had introduced in this branch.)
