The "ikwiki.cgi?page=index&do=edit" function has a problem
when running with [[debpkg thttpd]] or [[debpkg mini-httpd]]:
for some reason the headers ikiwiki outputs are transmitted
as the page content. Surprisingly, the "do=prefs" function
works as expected.
Here is what it looks like in iceweasel:
Set-Cookie: ikiwiki_session_apnkit=99dad8d796bc6c819523649ef25ea447; path=/

Ikiwiki runs fine with [[debpkg boa]].

It doesn't work for signin either.
What is the reason for these "header => 1" in FormBuilder initialisations?
Why do they appear two times with conflicting values in the very same hashes?
--[[JeremieKoenig]]
Clearly those duplicate header settings are a mistake. But in all cases, the
header => 0 came second, so it should override the other value and
can't be causing this problem. (cgi_signin only sets it to 0, too).
What version of formbuilder are you using? If you run ikiwiki.cgi at the
command line, do you actually see duplicate headers? I don't:
joey@kodama:~/html>REQUEST_METHOD=GET QUERY_STRING="page=index&do=edit" ./ikiwiki.cgi

Do thttpd and mini-httpd perhaps not realize that Set-Cookis is the start of
the headers? --[[Joey]]
Thanks for your help: I think I found the problem!
Ikiwiki outputs (in my case) the following
error message on stderr, followed by an empty line:
/srv/ikiwiki/wc/index.mdwn: (Not a versioned resource)
Probably thttpd and mini-httpd read stderr as well as stdout, while apache
and boa don't. When using a shell-script wrapper as the CGI,
which redirects ikiwiki's error output to /dev/null, it works better.
The edit still fails to commit, because in my wiki, index.mdwn is
pulled from the base wiki and somehow ikiwiki wants to change it
rather that create it.
--[[JeremieKoenig]]
If thttpd and mini-httpd interpret CGI's stderr as stdout, then
they're not properly following the CGI spec, and will break with tons
of cgi scripts besides ikiwiki. And of course there are many many cases
where ikiwiki might output to stderr, and that's the right thing to do.
So I don't see any way to address this in ikiwiki. --[[Joey]]
