Hi Chris,
I know we closed this issue back at the start of August, but I just
wanted to let you know that I realized today that I don't think it's
100% resolved. If you are using the "use first heading" option, and
the hierarchical breadcrumbs, and you come to a brand new DokuWiki
site that doesn't yet have the data cached yet, and you visit a link
other than "start", then you will only see the proper heading
information for the link that you visit in the breadcrumb bar, while
you will still see just IDs for the namespaces leading up to your
page. The breadcrumbs function needs to load metadata for the whole
path if it hasn't yet been loaded, and not just the metadata for the
current ID.
This shouldn't be happening. If it is it deserves further
investigation(*). When a request is made for a first headings, it can
be made with a flag that says generate metadata if it doesn't exist.
In general all calls should set that flag to true. The exception being
the metadata renderer. The default value of that flag is false, that
was done to avoid risking endless recursion two pages require a first
heading from each other. Perhaps that was incorrect. The metadata
renderer is really the only risk.
...
(*) I did a search on the DW codebase, there are several calls to
p_get_first_heading() which don't use the flag. Several in the
tpl_youarehere() function. Also my sidebar template (:)) and some
plugins. Switching the default value should fix any problems associated
with any of these and is, I think, the way to go.
Hi Chris,
I realized what the issue is... In my case, I'm starting a web site off
with pre-loaded data in the pages directory. When I visit an internal
page, the metadata for the other pages has not yet been rendered, so the
breadcrumb bar doesn't show it. I still consider this a bug because I
figure that the system should just get the metadata for all the headers
between the start and the page that I'm on if the functioin requires it,
but it isn't a huge big deal I guess....
Jason.
