November 09, 2004 Fix for endless loop with HTML files | ||||
---|---|---|---|---|
| ||||
Attachments: | The problem is when it encounters a '<' character, that is *not* followed by a valid tag start, according to istagstart() Such as: < CODE >, and similar constructs. Then it fails to advance the pointer (!), and keeps on scanning the '<' character forever. Inserting a "else p++;" works... You still need <code> and </code> in order for D to actually parse the code, but at least it comes back again with this patch. --anders |

Thanks! I don't think "< CODE >" is valid HTML, so this patch should be enough.

I don't think "< CODE >" is valid HTML, so this patch should be enough. I've run the attached file (with "< code>" and "</ code>")through the validator at http://validator.w3.org/check An got no warnings or errors. Thomas |

If you validate as XHTML, instead of the old HTML 4.0, you get the following validation errors (from same w3): 1. > Line 9, column 2: character "<" is the first character of a delimiter > but occurred as data > > < code > > > If you wish to include the "<" character in your output, you should > escape it as "<".

In general, XHTML and UTF-8 are now recommended instead of the old HTML 4.01 and ISO-8859-1... Anyway, nobody writes < code > in any real stuff. It's just that it's nice if D doesn't HANG on it. :-) --anders |
