mdwn: Can use the discount markdown library, via the
Text::Markdown::Discount perl module.
This is preferred if available since it's the fastest currently supported
markdown library, speeding up markdown rendering by a factor of 40.
That is to say, when only rendering a lot of markdown, discount is 40x
faster. When building a ikiwiki site, ikiwiki's other overhead gets in the
way, but I still see significant speedups. Building the ikiwiki docwiki
dropped from 62 to 45 seconds, for example.
However, when multimarkdown is enabled, Text::Markdown::Multimarkdown is
still used.
While discount contains some nonstandard markdown extensions,
including tables and footnotes, AFAICS most of them are not
enabled by default in the perl bindings.
I consider sticking to non-extended markdown a desirable thing, since this
is probably not the last markdown engine. In particular, sundown is waiting
in the wings to get packaged and get a perl binding.

Reviewing all the showdown extensions, here are the ones that are enabled:
centered paragraphs:
->centered<-
image sizes: [dust mite](http://dust.mite =150x150)
<style>..</style> blocks are eaten. The perl binding does not provide
access to the gathered CSS. This is not legal html anyway, so unlikely
to cause breakage.
We had a weird problem where, after moving to a new, faster server,
"git push" would sometimes fail like this:
Unpacking objects: 100% (3/3), done.
fatal: The remote end hung up unexpectedly
fatal: The remote end hung up unexpectedly
What turned out to be going on was that git-receive-pack was dying due
to an uncaught SIGPIPE. The SIGPIPE occurred when it tried to write to
the pre-receive hook's stdin. The pre-receive hook, in this case, was
able to do all the checks it needed to do without the input, and so did
exit(0) without consuming it.
Apparently that causes a race. Most of the time, git forks the hook,
writes output to the hook, and then the hook runs, ignores it, and exits.
But sometimes, on our new faster server, git forked the hook, and it
ran, and exited, before git got around to writing to it, resulting in
the SIGPIPE.
write(7, "c9f98c67d70a1cfeba382ec27d87644a"..., 100) = -1 EPIPE (Broken
pipe)
--- SIGPIPE (Broken pipe) @ 0 (0) ---
I think git should ignore SIGPIPE when writing to hooks. Otherwise,
hooks may have to go out of their way to consume all input, and as I've
seen, the races when they fail to do this can lurk undiscovered.
I have written to the git mailing list about this.
As a workaround, consume all stdin before exiting.
Using a file was sorta not right.
Note that when previewing, %pagestate is not saved, so
it has to rebuild the graph every time until that graph is saved;
then previews can use the cached data until the next time the graph
is changed.
Also note that it's stored in the destpage's pagestate. The imagemap
could vary between a page and an inlined page if wikilinks were supported.
Also, I let preview mode write real files, rather than using data: uri.
Which is ok these days, since ikiwiki tracks files created during
previewing, and cleans them up later.
In 875d550f12 I for some reason
made $page be changed when creating a discussion page, which
broke the link on the edit page. Changing page seems unnecessary,
so reverted that part of the change.
Involved dropping some checks for .svn which didn't add anything, since if
svn is enabled and you point it at a non-svn checkout, you get both pieces.
The tricky part is add and rename, in both cases the new file can be in
some subdirectory that is not added to svn.
For add, turns out svn has a --parents that will deal with this by adding
the intermediate directories to svn as well.
For rename though, --parents fails if the directories exist but are not
yet in svn -- which is exactly the case, since ikiwiki makes them
by calling prep_writefile. So instead, svn add the parent directory,
recursively.
tldr; svn made a reasonable change in dropping the .svn directories from
everywhere, but the semantics of other svn commands, particularly their
pickiness about whether parent directories are in svn or not, means
that without the easy crutch of checking for those .svn directories,
code has to tiptoe around svn to avoid pissing it off.
There's a nice message if the plugin is loaded and used and highlight is
not available, and a nice fallback. So no need for this other warning,
which can happen any time all plugins are loaded to generate a setup file.
This kind of change is scary, but this particular lock is very simply
used and so it seems ok to make it even just for better portability to
SunOS. (People still use that?)
* mercurial: openid nicknames are now used when committing. (Daniel Andersson)
* mercurial: implement rcs_commit_staged so comments, attachments, etc
can be used. (Daniel Andersson)
* mercurial: fix viewing of a diff containing non-utf8 changes.
(Daniel Andersson)
* rename: Fix logic error that broke renaming pages when the attachment
plugin was disabled.
* rename: Fix logic error that bypassed the usual pagespec checks.
If a page that looks like an email address exists, it can't be linked to.
But that's unlikely. Better to be consistent; before this change, a
wikilink with an email address in it could link to the email address or a
page, depending on when the page was created and when the page with the
link was updated.
Imagemagick does not generate svg images very well, but it can convert
them to png quite well.
For browsers that don't yet support displaying svg, this also provides a
workaround; just scale the svg down to get a png. But the workaround is
partial, since scaling the image larger, or leaving it the same size will
cause the original svg to be displayed. Since browsers are actively
improving svg support, this is good enough for me.
Firefox sent an accept header for application/xml, not application/json,
and also weakened the priority to 0.8. So that stuff is not to be trusted;
instead I found a better way: When an ajax upload is *not* being made,
the Upload Attachment button will be used, so enable ajax if an upload
is being made without that button having been used.
Also, testing with firefox revealed it refused to process a response that
was type application/json, and checking the demo page for the jquery file
upload plugin, it actually returns the json with type text/html. Ugh.
Followed suite.
Now tested with: chromium, chromium (w/o js), firefox, firefox (w/o js),
and w3m.
Needed for attachment to return json when requested.
I think some browsers send Accept: * , so I made sure to check that json
was explicitly listed as to be accepted, as well as having a high
priority.
Left out confirmation of removal for held attachments because
a) they're not in the wiki yet, so confirmation is a bit unnecessary
b) it would be hard
c) eases later integration of jquery file upload interface
Also changed where attachments of index are held (to match where they're
stored in the srcdir).
Note that the attachment formbuilder hook was made to run last, so that
the list of attachments is not generated before removal, in the fast path
w/o confirm.
Note that it's possible for an attachment in the holding area to be older
than an attachemnt in the wiki with the same name. I intentionally
show the one in the holding area in this (unlikely) case, since saving the
page will overwrite the wiki's file with the held attachment. It does not
seem worth the bother of doing something more intelligent, since in this
case two people have basically conflicted with one-another.. and both
attachment contents will be stored in revision control in case it needs to
be sorted out.
I had to remove the hyperlink for attachments in the holding area, since
they're not yet live on the web. This could be annoying/confusing. Added
a moseover notice instead.
This makes uploading a lot of attachments somewhat faster, because
the user does not need to wait for a long website refresh after each
upload. Still probably somewhat slow, since ikiwiki has to run for each
upload.
More importantly, this opens the door for integration of things like
the jquery file upload interface, which allow drag-n-drop and multiple
file uploads to be queued and then ran.
It uses rcs_commit_staged, which leaves out tla and mercurual which lack
that, but since rename, remove, autoindex, etc also use that, I think it's
fine for attachments to also depend on it.
The attachment list is currently broken; it does not look in the holding
area yet, and its links to the attached files won't work since they're not
yet in the wiki. previewing is also currently broken.

Two problems fixed:
1. Files are written with a .ikiwiki-new suffix, which has to be taken into
account.
2. Need to count length of bytes, not of unicode characters.
