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. |

README.Debian
It's a good idea, and in some cases a requirement, to rebuild your wikis when upgrading to a new version of ikiwiki. If you have a lot of different wikis on a system, this can be a pain to do by hand, and it's a good idea to automate it anyway. This Debian package of ikiwiki supports rebuilding wikis on upgrade. It will run ikiwiki-mass-rebuild if necessary when upgraded. The file /etc/ikiwiki/wikilist lists the setup files of wikis to rebuild, as well as the user who owns the wiki. Edit this file and add any wikis you set up. You can also allow users to maintain their own list of wikis to rebuild, by listing their usernames in /etc/ikiwiki/wikilist without corresponding setup files. ikiwiki will then read their lists of wikis from .ikiwiki/wikilist in their home directories. The examples directory contains the source to some example wiki setups.
