[users@httpd] Need help with #if DEBUGGING in proxy_http.c
Folks, we have been seeing quite a few 502 - (proxy: error reading status
line from remote server) with one of our backend server (very old Oracle
Web Application server 3.0 /HTTP 1.1) and I need to debug these request.
When I set LogLevel to debug, I still do not see the response stream
(bytes being transferred from the backend server to the Proxy) outputted
to the error log.
I only see this:
[Wed May 25 16:14:43 2005] [debug] ssl_engine_io.c(1489):
+-------------------------------------------------------------------------+
[Wed May 25 16:14:43 2005] [debug] proxy_http.c(956): proxy: header only
[Wed May 25 16:14:45 2005] [debug] proxy_http.c(893): proxy: start body
send
[Wed May 25 16:14:45 2005] [debug] proxy_http.c(953): proxy: end body send
[Wedder only May 25 16:14:45 2005] [debug] ssl_engine_io.c(1511): OpenSSL:
read 5/5 bytes from BIO#2ecce0 [mem: 3458d0] (BIO dump follows)
When I looked at the proxy_http.c, I see the following piece of code which
I guess is preventing writing to the debug log. I believe the #if (
conditional if) is a pre-complier flag used during compilation (?) or can
it be also be used during run time somehow by passing some argument ?
#if DEBUGGING
{
apr_off_t readbytes;
apr_brigade_length(bb, 0, &readbytes);
ap_log_error(APLOG_MARK, APLOG_DEBUG, 0,
r->server, "proxy (PID %d): readbytes:
%#x",
getpid(), readbytes);
}
#endif
Also, strangely enough, only mod_proxy module is using the #if DEBUGGING
pre-compiler flag, why !?
Thanks

Re: [users@httpd] Need help with #if DEBUGGING in proxy_http.c
Thanks Tejas for your response. It will def help me in the future.
But for now, even after I removed the #if debugging lines from the code
(proxy_http.c) and re-compiled Apache, I still do not see the Response
headers and body.
Here is my other follow-up submission to Apache org, can you help me with
the following too !? I have not touched C in the last 10 years, though I
can understand some of the code, not all of it. And plus to understand the
code, you have to study all the underlying structures/classes. And I need
to find/fix the problem asap. Thanks.
Hello again
I tried removing the #if debugging from proxy_http.c and re-compiled but
it did not help.
Can anybody offer me a piece of code which I can embed in proxy_http.c to
dump out the entire request (get/post parameters, cookies, etc.) being
passed to the backend and the corresponding response from the backend
including the headers and the body.
Thanks

Re: [users@httpd] Need help with #if DEBUGGING in proxy_http.c
Jignesh,
On which OS are you compiling Apache? If on UNIX, you can specify the flag
with ./configure, like:
./configure --prefix=<INSTALL_PATH> CFLAGS="-DDEBUGGING"
and then compile.
If on Windows, you have to add "-DDEBUGGING" for compiler flags in all the
.mak files.
The other way is to use "#define DEBUGGING" or "#define DEBUGGING 1" in
the
file in which you want it to be enabled.
Regards,
Tejas Sanghavi.

Hello again
I tried removing the #if debugging from proxy_http.c and re-compiled but
it did not help.
Can anybody offer me a piece of code which I can embed in proxy_http.c to
dump out the entire request (get/post parameters, cookies, etc.) being
passed to the backend and the corresponding response from the backend
including the headers and the body.
