Bug: Crash while editing new SVG file

Sfiera · Post by **Sfiera** » Sun Jun 10, 2007 2:58 pm

Just had a crash while trying to create a new SVG document. I pasted in the header (xml decl, doctype, svg open tag) from another SVG file and saw an error at the bottom to the effect of "unexpected EOF while parsing." I started to type the closing tag and got through "</", at which point svg Detective changed the error message to "EOF while parsing close tag for svg" and then crashed.

[Crashes aside, I would think it appropriate for svg Detective to provide a basic skeleton (xml decl, doctype, svg open and close tags) when a new document is created.]

I found the following in Console.log:

Code: Select all

Also, if I may add--perhaps it's not the best thing to bind the source window's content directly to the source. It would be better if the update was delayed for a second or so after editing stops. That would prevent lots of unnecessary (and often erroneous) parsing.

There are some bugs with the NSXML support when it comes to malformed XML (leading to crashes). I'm working on coming up with a better work around (yet still supports back to 10.3.9), but certainly adding a delay between editing and "re-rendering" would help to work around some of them.

I am not confident on this, but I believe libxml2 has been present on the system since at least 10.3.9. AppKit is linked to libxml2 on 10.4, so it's probably what NSXML is built against. I've never had trouble with software built against libxml2 (e.g. `xsltproc`) crashing, so it's probably a problem with Apple's code rather than the underlying XML parser.
