Saving a wiki page in ikwiki or
<tt>ikiwiki --setup wiki.setup --rebuild</tt> takes a **dozen minutes** on a tiny tiny wiki (10 user-added pages)!
I profiled ikiwiki with [[!cpan Devel::SmallProf]] : see [[users/mathdesc]] for details.
And I came to the conclusion that [[plugins/filecheck]] on attachment was the only cause.
It always go the fallback code using time-consuming file even there it's look like it's
not successful.
<pre>
# Get the mime type.
#
# First, try File::Mimeinfo. This is fast, but doesn't recognise
# all files.
eval q{use File::MimeInfo::Magic};
my $mimeinfo_ok=! $@;
my $mimetype;
if ($mimeinfo_ok) {
my $mimetype=File::MimeInfo::Magic::magic($file);
}
# Fall back to using file, which has a more complete
# magic database.
if (! defined $mimetype) {
open(my $file_h, "-|", "file", "-bi", $file);
$mimetype=<$file_h>;
chomp $mimetype;
close $file_h;
}
if (! defined $mimetype || $mimetype !~s /;.*//) {
# Fall back to default value.
$mimetype=File::MimeInfo::Magic::default($file)
if $mimeinfo_ok;
if (! defined $mimetype) {
$mimetype="unknown";
}
}
</pre>
I found on [[plugins/filecheck/discussion/]] what [[users/DavidBremner/]] described as :
> no way to detect text/plain using File::MimeInfo::Magic::magic()
But I can't figure out if my issue is boarder and includes this or not..
Any ideas , solve :) more that welcome.
