A malformed pagespec will cause $@ to be set when translated, but if
it is used a second time, the memoization will defeat that check. Better to
check for the result not being defined.
This avoids constructing urls like "./../foo/".
The leading "../" avoids any colon confusion already.
I noticed in my logs that certain badly written web spiders (hello again,
Yahoo!) fail to follow urls like ikiwiki was constructing to the right
place (instead ending up at "./foo/")
Since ikiwiki uses open :utf8, perl assumes that files contain valid utf-8.
If it turns out to be malformed it may later crash while processing strings
read from them, with 'Malformed UTF-8 character (fatal)'.
As at least a quick fix, use utf8::valid as soon as data is read, and if
it's not valid, call encode_utf8 on the string, thus clearing the utf-8
flag. This may cause follow-on encoding problems, but will avoid this
crash, and the input file was broken anyway, so GIGO is a reasonable
response. (I looked at calling decode_utf8 after, but it seemed to cause
more trouble than it was worth. BTW, use open ':encoding(utf8)' avaoids
this problem, but the corrupted data later causes Storable to crash when
writing the index.)
This is a quick fix, clearly imperfect:
- It might be better to explicitly call decode_utf8 when reading files,
rather than using the IO layer.
- Data read other than by readfile() can still sneak in bad utf-8. While
ikiwiki does very little file input not using it, stdin for the CGI
would be one way.
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.
* Stop busy-waiting in lockwiki, as this could delay ikiwiki from waking up
for up to one second. The bailout code is no longer needed.
* Remove support for unused optional wait parameter from lockwiki.
This fixes a problem exposed by the recent change to tags
(a2839de936). That recorded tag links as
absolute by including a leading slash in the link. The same could also be
done with an absolute wikilink.
In either case, link() would not match such links, unless the leading slash
was included in the link to match. But that's not right, because pagespecs
match absolute by default. So strip the leading slash.
Note that to keep any existing `link(/foo)` pagespecs working after this
change, the leading slash is removed from there, too.
Add an inject function, that can be used by plugins that want to replace
one of ikiwiki's functions with their own version. (This is a scary thing
that grubs through the symbol table, and replaces all exported occurances
of a function with the injected version.)
external: RPC functions can be injected to replace exported functions.
Removed the stupid displaytime hook, and use injection instead.
Need to use a hook because an exported function cannot be reliably
overridden. The replacement verstion was actually only affecting plugins
loaded after it.
formattime doesn't need a hook, since there's no reason to export it.
This is the easy part of supporting foo/index.mdwn sources for page foo.
Note that if foo.mdwn exists too, there will be a warning about multiple
sources for the same page, and which is used is indeterminate.
indexpages should also cause web based editing to create index source pages
by default; this and other fallout of the option not yet implemented.
Upgrades to the new index format should be transparent.
The version field is 3, because 1 was the old textual index, 2 was the
pre-versioned format.
This also includes some efficiency improvements to index loading, by
not copying a hash and using a reference.
Setting the values in the setup file by default makes it annoyingly hard to
override them at the command line (since setup files override the command
line).
Both default to off if no value is set.
Move rcs plugin load to loadplugins; move duplicate rcs detection logic out
of individual plugins and into loadplugins. Avoids checkconfig failing when
run twice.
The fix for colons involved adding "./" to some urls. Due to the weird way
inline called urlto, these snuck into feed urls and permalinks. Fix it by
adding an optional third parameter to urlto.
* Renamed to parentlinks every single variable or function called
pedigree
* Removed the parentlinks function from Render.pm
* Enabled the new parentlinks plugin by default
* Adapted testsuite and documentation to reflate the above facts

This reverts commit e25c3a0a7c.
I didn't think that through far enough; beautify_url may be called on full
urls, which don't start with "/"!
Conflicts:
debian/changelog
So the problem is that ikiwiki would generate a relative link like
href="colon:problem", which web browsers treat as being in the "colon:"
uri scheme.
The best fix seems to be to make url beautification fix this, by slapping
a "./" in front.
* 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.
This special case crops up when generating the parentlink to the toplevel
index page. urlto("") had been generating a link to "./" (or "../" etc)
for that, which is fine, if the web server redirects that to the toplevel
index.html. It's less fine if there is no web server.
I actually ran into the problem first when using gopher. (Yes, yes, don't
laugh.. see upcoming tip.) But it also crops up when browsing local wiki
files.
Of course, the index.html is stripped back off if usedirs is enabled.
Because the search plugin needed it, also because it's one of the few
plugins that didn't already have it.
I also considered adding it to htmlize, but I really cannot imagine caring
what the destpage is when htmlizing. (I'll probably be poven wrong later.)
<mxey> I have a weird problem with Ikiwiki on FreeBSD: When rendering this page <http://rafb.net/p/zmfROX86.html>, I get "ikiwiki.setup: Modification of a read-only value attempted at /usr/local/lib/perl5/site_perl/5.8.8/IkiWiki.pm line 1300.".
And converting the constructors to not operate on the parameters directly
but use lexical variables fixed it. Not sure exactly when this occurs.
This manifested as wikis with no locked pages treating them all as locked.
The bug was introduced in version 2.41.
Medium urgency upload due to above fix.
