This is needed so that when a negated pagespec like "!author(foo)"
stops matching, due to the page being changed, ikiwiki knows that
the match was influenced by the page content.
The commit that added the (working) support for using /tag to override
tagbase also tried to make ./tag work. Problem is, tags are links,
and ./foo is not a valid link (though I think there's a wishlist about it).
So, using ./tag really resulted in tag creation links that led to a
"bad page name" error. And even if the tag were created in the right place,
the link didn't go to it.
loadindex does not bother populating oldtypedlinks if there is no link
type. However, the code in link_types_changed assumed that if oldtypedlinks
is not defined, and typedlinks is, they must differ.
This fixes the problem that it did not remember if an autofile is deleted,
unless a plugin happened to register the autofile at the same time.
With the new code, we just never recreate an autofile more than once.
Only downside is that the list of autofiles is never pruned either.
And I don't really see a way to prune it.
Splitting out this function bothered me. It is conceptially similar to
file_pruned, and yet also very specific to exactly the security needs of
find_src_files.
I liked that it got rid of duplicate code in the latter function. So
instead, put a helper sub in that, which I think allows refactoring
things more cleanly, and with less boilerplate.
As to the needs of gen_autofile, I'm not convinced this needs to handle
the same set of problems that verify_src_file did. So I sat down and
wrote a custom validator for autofiles, which turned out to seem to just
need three things: Make sure the candidate filename is not something
that would be pruned; untaint the candidate filename; and make sure that
srcdir doesn't already have something with its name. (Plus, of course,
all the other checks that were already in gen_autofile.)
(In passing, also fixed a bunch of bugs I had introduced in this branch.)
By a stroke of luck, after a long & full day, I happened to
remember that in the morning, I had seen someone on irc mention
that darcs query manifest doesn't like it if its full output
is not consumed.
So contrary to the usual case where bug reports sent via irc are like
messages written in sand before the new tide, this one was seen and
fixed.
(But use http://ikiwiki.info/bugs/ next time!)
$cgi->params('do') may not be defined. The CSRF code may delete all
cgi params. This uninitalized value was introduced when do=register
support was added recently.
Many calls to file_prune were incorrectly calling it with 2 parameters.
In cases where the filename being checked is relative to the srcdir,
that is not needed.
Made absolute filenames be pruned. (This won't work for the 2 parameter call
style.)
A tag like ./foo is searched for relative to the tagging page.
However, if multiple pages use such a tag, the only one sure
to be in common is in the root, so autocreate it there to
avoid scattering redunadant autocreated tags around the tree.
(This is probably not ideal.)
Also renamed the tagpage and taglink functions for clarity.
Made add_autofile take a generator function, and just register the
autofile, for later possible creation. The testing is moved into Render,
which allows cleaning up some stuff.
This is a slow implementation; it runs svn log once per file
still, rather than running svn log once on the whole srcdir.
I did it this way because in my experience, svn log, run on a directory,
does not always list every change to files inside that directory.
I don't know why, and I use svn as little as possible these days.
