Setting up a new highlighter object is slightly expensive since it
reads and parses the langfile each time. So cache them.
This also speeds up ext2langfile by avoiding it needing to check for the
existence of a language file in some cases.
format: Provide a htmlizefallback hook that other plugins can use to
handle formats that are not suitable for general-purpose htmlize hooks.
highlight: Use the hook to allow formatting of any language/extension,
without it needing to be enabled for standalone source files.
highlight: If the highlight perl binding is not available, fallback
safely to a passthrough mode.
We build an array of [ plugin name, long name ] pairs, where long name
is an optional argument to hook(). So, a syntax plugin could define
long "friendly" name, such as "Markdown" instead of mdwn, and we would
then pass this array to formbuilder to populate the drop-down on the
edit page.
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.
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.
This reverts commit 2f96c49bd1.
I forgot about internal pages. We don't want * matching them!
I left the optimisation in pagecount, where it used to live.
Internal pages probably don't matter when they're just being
counted.
I forgot to check if it was called from preprocess, and it is
not; it's called by a format hook. If an error is thrown from
a format hook, wiki build fails, so we don't want that.
* 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.
The munged ids were looking pretty nasty, and were not completly guaranteed
to be unique. So a md5sum seems like a better approach. (Would have used
sha1, but md5 is in perl core.)
Well, that was a PITA.
Luckily, this doesn't break guids to comments in rss feeds,
though it does change the links.
I haven't put in a warning about needing to rebuild to get
this fix. It's probably good enough for new comments to get the
fix, without a lot of mass rebuilding.
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.)
I guess what's happening here is that since the name
is passed to git via an environment variable, perl's normal
utf-8 IO layer stuff doesn't work. So we have to explicitly
decode the string from perl's internal representation into
utf-8.
This change was introduced in 85f865b5d9 and
c3af3840a2 ; it may be necessary for the meta-po
integration, but the po branch alone is supposed to work without it.

This makes wikis such as zack's much faster in the scan pass.
In that pass, when a template contains an inline, there is no reason to
process the entire inline and all its pages. I'd forgotten to pass
along the flag to let preprocess() know it was in scan mode, leading to
much unncessary churning.
- In 3.05, ikiwiki began expanding templates in scan mode,
for annoying, expensive, but ultimatly necessary reasons
of correctness.
- Smiley processing has a bug: It inserts a span for the smiley,
and then continues searching forward in the content for more,
starting at $end_of_smiley+1. Which means it searches for smilies
in the span too! And if it somehow finds one, we get an infinite loop
here.
- This bug can, probably, only be tickled if a htmllink to
show the smiley fails, because the smiley file doesn't exist,
or because ikiwiki doesn't know about it. In that case,
a link will be inserted to _create_ the missing page,
and that link will include the smiley inside the <a></a>.
- When a template is expanded in scan mode, and it contains
an inline, the sanitize hook is run during scan mode,
which never happened before. That causes the smiley processor
to run, before ikiwiki is, necessarily, aware that all
the smiley files exist (depending on scan order). So
it inserts creation links for them, and triggers the bug.
I've put in the simple fix of jumping forward past the inserted
span, and it does fix the problem. I will need to look in a bit
more detail into why an inline nested inside a template is
fully expanded during the scan pass -- that really shouldn't
be necessary, and it makes things much slower than they need
to be.
... as Joey suggested on todo/need_global_renamepage_hook
This hook is applied recursively to returned additional rename
hashes, so that it handles the case where two plugins use the hook:
plugin A would see when plugin B adds a new file to be renamed.
The full set of rename hashes can no longer be changed by hook functions, that
are only allowed to return any additional rename hashes it wants to add.
Rationale: the correct behavior of the recursion would be hard, if not
impossible, to define, if already considered pages were changing on the run.

This means that the underlay needs to have a wmd/wmd/wmd.js,
which is a trifle weird, but it isolates all the wmd stuff in a
single wmd subdirectory of the built wiki. The wmd/images creating
a toplevel images directory was particularly bad.
This is likely a misconfiguration and can cause login to fail as the
browser refuses the send the session cookie back over http.
Not entirely happy with putting the check where I did, since users have to
try to log in, and fail, to see the misconfiguration explained. But I could
not find a better place to put the check.
This is potentially expensive, but is necessary so that meta and tag
directives, and other links on templates affect the page using the template
reliably.
It no longer makes sense to keep these functions in editpage, because
serveral plugins now exist that use them, and users may want to disable
editpage, while leaving those plugins enabled.
Most notably, comments uses both functions, and it's entirely appropriate
to disable editpage but still want to have comments enabled.
Less likely, attachments, rename, and remove all use check_canedit -- but
it would be unusual indeed to want to use these w/o editpage.
Falls back to looking for shortcuts.mdwn for backwards compatabiity; there
probably exist wikis that have changed the pageext but still use
shortcuts.mdwn.
See [[bugs/Aggregated_Atom_feeds_are_double-encoded]]. By default,
XML::Atom outputs strings of UTF-8 bytes with the Perl UTF8 flag stripped
off, which IkiWiki assumes to be Latin-1 and re-encodes as UTF-8 on
output. XML::Feed does not currently (0.41-1) set the magic variable to
change this behaviour (I've filed a bug on CPAN), but IkiWiki can
usefully set the same variable as a workaround.
This may already work with other web servers that have copied apache's
interface, and it should be easy to add support to it for web servers that
use some other interface. So, make the name more general.
