+Okay, I'll provide the log as an link in the wiki. But there should be a kind of mechanism how they can be removed. This could lead to an DOS (create via a bot so much nonsense code that the disk is full.)

+Fixed, the log is now provided if latex will fail.

 > The url handling could stand to be improved. Currently it uses $config{url}, so it depends on that being set. Some ikiwiki builds don't have an url set. The thing to do is to use urlto(), to generate a nice relative url from the page to the image.

+Yes of course, I'll improve the url handling. My comment was only about the several folder ;-)
+
+Fixed. Now I use urlto and will_render.

 > Another (minor) problem with the url handling is that you put all the images in a "teximages" directory in the toplevel of the wiki. I think it would be better to put each image in the subdirectory for the page that created it. See how the `img` and `sparkline` plugins handle this.
 
 > It looks like if the tempdir already exists, tempdir() will croak(), thus crashing ikiwiki. It would be good to catch a failure there and fail more gracefully.

+Fixed. I now use eval { create_tmp } and then:  if ($?) { $returncode = 0 } else { save .tex file ... } ...

+Okay here an short timetable how I want to proceed further:
+
+* Until weekend (21-22. July) I'll try to fix all errors above. (done)
+* From 22.July until 29. July I'll try to set up a first security check
+  My plans are two parts of a security check:
+    * One with an array of blacklisted regular expression. (This would blacklist all the well known and easy to fetch things like \include {/path/to/something} and things like closing the math formula environment ($$). (done)
+    * the second step will be based on Tom::latex, which will help to parse and get a tree view of the code.
+
+Okay what do you think of this procedure?

+
+Thanks for the comment.. is fixed. 
+Mh... not really fixed :S I added it into the return but it is somehow ignored. I'll figure out why.
