Fixing a bug : a personal report

2012/3/20 François Gannaz francois.gannaz@gmail.com

Hi

I wrote a report of my first dive into php-src in an attempt to fix a bug.
https://github.com/mytskine/php-src/wiki/bug40531-mbsubstr
I tried to detail everything as a personal memo, then for a friend of mine,
and now I've put it into a github wiki page.

I wonder if it can be useful to anyone. If you have the time to read it,
I'm
very interested in any comments, especially on the technical parts
(integers,
null values and zval). Please don't be to harsh if I misunderstood
something.

That's a really nice resource, François. I can't speak to the technical
accuracy, as I've not developed a PHP extension or worked in the core yet.
However, as someone who will be exploring a few core ideas in the near
future, this is really helpful.

Thanks!

Adam
