Re: Re: HTTP doesn't work after upgrading from 2.0.55 to 2.2.15

Hi William,

This is the place I found the 0 and 5 length bucket, cgi_read_stdout() in cgi_bucket_read() in mod_cgi.c which is the function for reading the data from the CGI bucket. So can I say that mod_cgi is the module my Apache uses instead of the mod_cgid. (And I didn't see the mod_cgid through "httpd -l" command)

Is the problem possible in the CGI or mod_cgi, just like the prediction I did in the former post?

Thanks

Best regards,

honercek

There is no bug in the core, when EOS is hit, that's it.

What module creates this missing 5 byte bucket?  Was it a 0 len chunk header?
If that never hits the wire, it sounds like it could be a bug, but I've seen
no other reports of similar buggy behavior in 2.2.15, so I tend to suspect a
module, and most likely an external one.
