Description:
I have a mediawiki site hosted by bluehost.com and all of a sudden I started
getting apache 500 errors on a mediawiki site that was not modified. bluehost
is using php 5.1.6 and apache 1.3.37 on linux 2.6.17-11_4.BHsmp, mysql
4.1.21-standard-log. bluehost says they didn't change anything (php binary
itself has not changed).
Playing around with a separate installation on my bluehost site, I narrowed it
down to wfGetCaller in includes/GlobalFunctions.php. In particular, the
debug_backtrace call can fail. This is, I believe, a builtin C function for
php, but I'm not sure what else I can do at this point and maybe someone else
can get some more info in case this error starts becoming more widespread.
For now, I guess I can just have wfGetCaller return "unknown" and hence bypass
the call to debug_backtrace, but there's something more (and interesting) going
on here.
I'm sorry, but I don't have an explicit test case right now - if there's
something else I can spit out before the debug_backtrace call (which has no
arguments to report here) that might be useful let me know.
