Re: In what condition, can this log message be printed?

Hi, Eric,

I'm sorry for the disturbing for this problem.

I used GDB to trace the code, in the hope of understanding why httpd never print that log message.

Basically, that following code print out the log message:

/* server/mpm/event/event.c */

3182         ap_log_error(APLOG_MARK, APLOG_INFO, 0, NULL, APLOGNO(00521)

3183                      "MaxClients is deprecated, use MaxRequestWorkers "

3184                      "instead.");

 

and at the startup, the system did execute this logging statement.

but when go inside the ap_log_error function, it fails into the following if condition:

/* server/log.c */

1120         /*

1121          * If we are doing stderr logging (startup), don't log messages that are

1122          * above the default server log level unless it is a startup/shutdown

1123          * notice

1124          */

1125 #ifndef DEBUG

1126         if ((level_and_mask != APLOG_NOTICE)

1127             && (level_and_mask > ap_default_loglevel)) {

1128             return;

1129         }

1130 #endif

Here, level_and_mask is 6 (APLOG_INFO), and ap_default_loglevel is 4. So the code simply returned without printing the log message, and that's why I never had chance to see the log message.

I have the following two questions:

1. How to enable the DEBUG macro in this case?

2. Is this behavior on purpose? because I think most httpd are not enabled with DEBUG, so this kind of information is hardly to be noticed.

Many thanks,

Tianyin

No no, what I mean is that I never configured "MaxRequestWorkers" but I configured "MaxClients".

But I never see the log messge ""MaxClients is deprecated, use MaxRequestWorkers instead".

I just wonder where can I find these types of log messages in my system.

Thanks a lot!
