Speedup of about 25% for small inlines; could be much larger for inlines of
many, or complex pages.
Not bloating memory with excessive memoization data was the key to this.
The method chosen does not squeeze out every erg of speed possible when
inlines are nested, but that's rare. It uses less memory than other
optimisation hacks (I'm looking at you,
f937c1fb80 !) already used in inline.pm.
My experience is that when inlines are nested, the old behavior of
generating feeds for the nested inlines was never really desired. Since the
feeds were numbered sequentially, the numbers could easily change, and it did
not make sense to subscribe to or use those feeds. And generating those nested
feeds often meant a lot of unnecessary calculation, and data being written.
So, I dropped them.
Looking back, nested feeds originally were a free side effect of properly
handing multiple feeds on one page. Of course, that is still supported.
This dependency was missing before switching to use_pagespec.
It is correct to add it, but it needs to be combined with the regular
"pages" dependency to ensure that it does not match extra pages.
(Also fixed its dependency type.)
This is unnecessary and just slows us down (by a factor of 2, in the
pessimal case where every page has an inline with pagenames); it's also
not possible to optimize it into add_depends_exact calls.
The po plugin's injected bestlink must do something special when called by this
exact part of inline's code.

The new dependency handling works better (eliminates more duplicates) if
dependencies are split up. On the same wiki mentioned in the previous
commit, this saves about a second (i.e. 4%) on the same test.
This is both faster, and propigates any error in processing the feedpages
pagespec out to display on the page. Which may have been why I didn't use
it before, but currently seems like a good thing to do, since it explains
why your feeds are empty..
By adding this setting, we get both more configurability, and a minor
optimisation too, since gettext does not need to be called continually
to get the Discussion value.
If given instead of pages, this is interpreted as a space-separated
list of links to pages (with the same LinkingRules as in a WikiLink),
and they are inlined in exactly the order given. The sort and pages
parameters cannot be used in conjunction with this one.
When finding the pageurl, it was calling bestlink unnecessarily.
Since at this point $page contains the full name of the page that
is being inlined, there is no need to do bestlink's scan
for it.
This is only a minor optimisation, since bestlink is only called
once per displayed, inlined page.
* pagespec_match_list: New API function, matches pages in a list
and throws an error if the pagespec is bad.
* inline, brokenlinks, calendar, linkmap, map, orphans, pagecount,
pagestate, postsparkline: Display a handy error message if the pagespec
is erronious.
* Add IkiWiki::ErrorReason objects, and modify pagespecs to return
them in cases where they fail to match due to a configuration or syntax
error.
* inline: Display a handy error message if the inline cannot display any
pages due to such an error.
This is perhaps somewhat incomplete, as other users of pagespecs do not
display the error, and will eventually need similar modifications to inline.
I should probably factor out a pagespec_match_all function and make it throw
ErrorReasons.
It would be better to use urlto() here, but will_render
has not yet been called on the feed files at this point, so
it won't work. (And reorganizing so it can be is tricky.)
Some aggregators, like Planet, sort by mtime rather than ctime. This
means that posts with modified content come to the top (which seems odd
to me, but is presumably what the aggregator's author or operator
wants), but it also means that posts with insignificant edits (like
adding tags) come to the top too. Atom defines <updated> to be the date
of the last *significant* change, so it's fine that ikiwiki defaults to
using the mtime, but it would be good to have a way for the author to
say "that edit was insignificant, don't use that mtime".
inline has a format hook that is an optimisation hack. Until this hook
runs, the inlined content is not present on the page. This can prevent
other format hooks, that process that content, from acting on inlined
content. In bug ##509710, we discovered this happened commonly for the
embed plugin, but it could in theory happen for many other plugins (color,
cutpaste, etc) that use format to fill in special html after sanitization.
The ordering was essentially random (hash key order). That's kinda a good
thing, because hooks should be independent of other hooks and able to run
in any order. But for things like inline, that just doesn't work.
To fix the immediate problem, let's make hooks able to be registered as
running "first". There was already the ability to make them run "last".
Now, this simple first/middle/last ordering is obviously not going to work
if a lot of things need to run first, or last, since then we'll be back to
being unable to specify ordering inside those sets. But before worrying about
that too much, and considering dependency ordering, etc, observe how few
plugins use last ordering: Exactly one needs it. And, so far, exactly one
needs first ordering. So for now, KISS.
Another implementation note: I could have sorted the plugins with
first/last/middle as the primary key, and plugin name secondary, to get a
guaranteed stable order. Instead, I chose to preserve hash order. Two
opposing things pulled me toward that decision:
1. Since has order is randomish, it will ensure that no accidental
ordering assumptions are made.
2. Assume for a minute that ordering matters a lot more than expected.
Drastically changing the order a particular configuration uses could
result in a lot of subtle bugs cropping up. (I hope this assumption is
false, partly due to #1, but can't rule it out.)
Jumping to the just posted comment was the imputus, but I killed a number
of birds here.
Added a INLINEPAGE template variable, which can be used to add anchors to
any inline template.
To keep that sufficiently general, it is the full page name, so the
comment anchors and links changed form.
Got rid of the FIXMEd hardcoded html anchor div.
More importantly, the anchor is now to the very top of the comment, not the
text below. So you can see the title, and how it attributes you.
Avoid changing the permalink of pages that are not really comments, but
happen to contain the _comment directive. I think that behavior was a bug,
though not a likely one to occur since _comment should only really be used
on comment pages.
I wanted this nearer to the top, but decided to put it after the
add_depends. Reasoning: It's possible with a combinaton of feedpages and
show options to make @list and @feedlist contain completly differing sets
of pages. We want to add_depends all pages in both sets. We could combine
the two lists and add_depends that, but it's slightly more efficient to
defer reducing @feedlist, and add_depends whichever list is longer.
