None of the comment state needs to be stored through the a later run of
ikiwiki, so move it all from pagestate to a more transient storage.
This is assuming that we'll never want to add pagespecs to search against
the comment state. Pagespecs like author() are why the meta plugin does
store its meta data in pagestate -- the data can be needed later to match
against.
The thinking here is that having both a Discussion page and comments for
the same page is redundant, and certianly not what you want if you enable
comments for a page. At first I considered making configurable via pagespec
what pages got discussion links. But that would mean testing a new pagespec
for every page, and a redundant config setting to keep in sync. So intead,
take a lead from my previous change to make inlined pages have a comments
link, and change the discussion link at the top of regular pages to link to
their comments.
(Implementation is a bit optimised to avoid redundant pagespec checking.)
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 think it is clearer to have one pagespec that controls all pages with
comments, and a separate pagespec that can be used to close new comments on
a subset of those pages.
Not compacting whitespace is the most important one: now that we run
sanitize hooks on individual posted comments in the comments plugin,
whitespace that is significant to Markdown (but not HTML) is lost.
(cherry picked from commit cb5aaa3cee)
The [[!_comment]] directive is a serialization format, not something for
presentation to users, so we should use the least ambiguous possible
representation.
This delays all comment formatting until the last possible time, allows
us to set metadata without worrying that commenters may be able to evade
it, and means that changes to how a comment is saved can be handled
gracefully. It also gives us somewhere to put the commenter's username
or IP address for later reference.

This should ensure that users can't "break out" from the enclosing
<div>, making it impossible to forge comments (assuming htmlscrubber
is enabled, and so is either htmlbalance or htmltidy).
wikilinks are harmless, so we might as well allow them.
Access control for this plugin is a bit odd, since we specifically
don't want to allow comments to be edited - so the check is whether the
user is allowed to edit a deliberately invalid page name,
page/commented/on[smcvpostcomment]. You can put smcvpostcomment(*)
or smcvpostcomment(some/subdir/*) in $config{anonok_pagespec}
or the opposite in $config{locked_pages} to allow "editing" (really
just posting) comments.
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.
holger reported that decode_utf8 was crashing with perl 5.8.8. Earlier, I
thought that passing 0 to the function avoided this with old perls, but
that was apparently not enough, it still crashes. So, put it inside the
eval, so we can at least recover from it crashing.
The old code actually did the same thing, just obfuscated -- since the eval
use wasn't quoted, it used the modules on load. Thus, the error (not to
mentioned the return) was bypassed, and it just failed on load.
But that seems like the right thing to do, really, so just made it clearer
that's what happens.
This is necessary so that things that fork to the background,
like pinger, and inline ping, don't block other cgis from running.
Note that websetup also calls unlockwiki, before refreshing / rebuilding
the wiki. It makes perfect sense for that not to block other cgis.
