This is sorta an optimisation, and sorta a bug fix. In one
test case I have available, it can speed a page build up from 3
minutes to 3 seconds.
The root of the problem is that $links{$page} contains arrays of
links, rather than hashes of links. And when a link is found,
it is just pushed onto the array, without checking for dups.
Now, the array is emptied before scanning a page, so there
should not be a lot of opportunity for lots of duplicate links
to pile up in it. But, in some cases, they can, and if there
are hundreds of duplicate links in the array, then scanning it
for matching links, as match_link and some other code does,
becomes much more expensive than it needs to be.
Perhaps the real right fix would be to change the data structure
to a hash. But, the list of links is never accessed like that,
you always want to iterate through it.
I also looked at deduping the list in saveindex, but that does
a lot of unnecessary work, and doesn't completly solve the problem.
So, finally, I decided to add an add_link function that handles deduping,
and make ikiwiki-transition remove the old dup links.
* teximg: The prefix is configurable, and has changed to not include the
nonstandard mhchem by default. (willu)
* teximg: dvipng is used if available to render images. Its output is
antialiased and better than dvips. If not available, the old dvips+convert
chain will be used. (willu)
* Drop suggests on texlive-science, add suggests on dvipng.
* The editpage form now uses the raw page name, not the page title, in its
'page' cgi parameter. Using the title was ambiguous and made it
impossible to tell between some pages, like "foo/bar" and "foo__47__bar",
sometimes causing the wrong page to be edited.
* This change means that some edit links need to be updated.
Force a rebuild on upgrade to this version.
* Above change also allowed really fixing escaped slashes from the blogpost
form.
Add a prefix_directives option to the setup file to turn this syntax
on; currently defaults to false, for backward compatibility. Support
optional '!' prefix even with prefix_directives off, and use that in
the underlay to support either setting of prefix_directives. Add NEWS
entry with migration information.
links required meta to be run during scan, which complicated its data
storage, since it had to clear data stored during the scan pass to avoid
duplicating it during the normal preprocessing pass.
* If you used "meta link", you should switch to either "meta openid" (for
openid delegations), or tags (for internal, invisible links). I assume
that nobody really used "meta link" for external, non-openid links, since
the htmlscrubber ate those. (Tell me differently and I'll consider bringing
back that support.)
* meta: Improved data storage.
* meta: Drop the hackish filter hook that was used to clear
stored data before preprocessing, this hack was ugly, and broken (cf:
liw's disappearing openids).
* aggregate: Convert filter hook to a needsbuild hook.
and forces rebuilds of the pages that contain calendars. So
running ikiwiki --refresh at midnight is now enough, no need for a full
wiki rebuild each midnight.
* calendar: Work around block html parsing bug in markdown 1.0.1 by
enclosing the calendar in an extra div.
and style sheet updates, and unless you're using customised versions,
you'll want to rebuild wikis on upgrade to this version to avoid
inconsistencies.
* Allow WIKINAME to to used in footers, as an example of something to put
there.
plugins's support for inserting html link and meta tags. Now such content
is passed through the htmlscrubber like everything else.
* Unfortunatly, that means that some valid uses of those tags are no longer
usable, and special case methods needed to be added for including
stylesheets, and for doing openid delegation. If you use either of these
in your wiki, it will need to be modified. See the meta plugin docs
for details.
were titlepage escaped in the urls, and then doubly escaped by the CGI
when editing. To fix this, I removed the titlepage escaping in the edit
urls.
* That means that *every edit link* on the wiki is potentially changed.
Rebuilding wikis on upgrade to this version therefore necessary; enabled
that in postinst.
parameters remain the same, but additional options are now passed in using
named parameters.
* Change plugin interface version to 1.02 to reflect this change.
* Add a new anchor option to htmllink. Thanks Ben for the idea.
* Support anchors in wikilinks.
* Add a "more" plugin based on one contributed by Ben to allow implementing
those dreaded "Read more" links in blogs.
