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.
* Automatically run --gettime the first time ikiwiki is run on
a given srcdir.
* Optimise --gettime for git, so it's appropriatly screamingly
fast. (This could be done for other backends too.)
* However, --gettime for git no longer follows renames.
* Use above to fix up timestamps on docwiki, as well as ensure that
timestamps on basewiki files shipped in the deb are sane.
* Rename --getctime to --gettime. (The old name still works for
backwards compatability.)
* --gettime now also looks up last modification time.
* Add rcs_getmtime to plugin API; currently only implemented
for git.
There's a gotcha where pagespec_match_list is used with a dependency type
that is not a full content dependency, and so ikiwiki does not know that
a content change to a page that sorted too low to match needs to trigger
a rebuild, since its sort order may have changed.
Inline is mostly ok re this, as it does use content dependencies. Except
for in the case of raw mode. But then, page metadata is documented to not
be loaded, so it doesn't make sense to use sortspecs that depend on
metadata. I hope. :)
As I was adding ngettext support, I realized I could optimize the gettext
functions by memoizing the creation of the gettext object. Note that
the object creation is still deferred until a gettext function is called,
to avoid unnecessary startup penalties on code paths that do not need
gettext.
A side benefit is that separate stub functions are no longer needed to
handle the C language case.
I made match_* functions whose influences can vary depending on the page
matched set a special "" influence to indicate this.
Then add_depends can try just one page, and if static influences are found,
stop there.
