$ newlisp -c -d 8080 -w ./
*** glibc detected *** double free or corruption (!prev): 0x08086f28 ***
Aborted
What happened?
I started the above, then eneter the url localhost:8080

Norman.
At the moment I only have Win32, Mac OS X and FreeBSD available where things work fine. I will not have access to a Linux system until later. What flavor of Linux are your running?
Lutz
Hi Lutz,
Slackware 11.0 with Kernel -> 2.4.33.3
Norman.
Thanks Norman, I could repeat the problem on Debian Linux and could fix it.
Lutz
Hi Lutz,
I thought it was gone in 9.0.7 for a while.., but its back...
Its not the same crash..this time its more a free() issue..of a pointer..
$ newlisp httpd.conf -c -d 54080 -w ./
*** glibc detected *** free(): invalid pointer: 0x40018000 ***
Aborted
Hard to reproduce now... but im trying...
Norman.
Make sure that the 'http-conf' definition always returns a string. The first CHANGES file I posted had returned a 'nil' under default conditions. 9.0.7 takes any return as a string pointer, that is probably what caused the crash. The corrected httpd.conf looks like this:
(if (ends-with request ".exe") "errorpage.html" request))
The function can be used to rewrite incoming URLs, test for unsecure file types, directories etc., but always must return a string, which is typically the request itself if it was safe. 9.0.8 will test for string and assume the original request if no string is returned.
Lutz
Aha ..oke... that could indeed be the problem because i was expirimenting with
the httpd.conf file indeed...
