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
Use ./Makefile.PL to generate a Makefile, "make" will build the documentation wiki and a man page, and "make install" will install ikiwiki. All other documentation is in the ikiwiki documentation wiki, which is also available online at <http://ikiwiki.info/> A few special variables you can set while using the Makefile: PROFILE=1 turns on profiling for the build of the doc wiki. (Uses Devel::Profile) NOTAINT=0 turns on the taint flag in the ikiwiki program. (Not recommended unless your perl is less buggy than mine -- see http://bugs.debian.org/411786) There are also other variables supported by MakeMaker, including PREFIX, INSTALL_BASE, and DESTDIR. See ExtUtils::MakeMaker(3). In particular, INSTALL_BASE is very useful if you want to install ikiwiki to some other location, as it configures it to see the perl libraries there. See `doc/tips/nearlyfreespeech.mdwn` for an example of using this to install ikiwiki and its dependencies in a home directory.
