SunOS joplin 5.6 Generic_105181-10 sun4u sparc SUNW,Ultra-5_10
using GCC
>Description:
Although load_module() [in file mod_so.c] is calling
ap_log_error(..., APLOG_DEBUG|APLOG_NOERROR, NULL, "loaded module %s", ...)
the log message never appears in the actual "error_log" file.
This is because load_module() is passing a NULL server_rec * pointer to
ap_log_error() [in file http_log.c]. ap_log_error() calls log_error_core()
which
does the following:
if (s == NULL) {
/*
* If we are doing stderr logging (startup), don't log messages that are
* above the default server log level unless it is a startup/shutdown
* notice
*/
if (((level & APLOG_LEVELMASK) != APLOG_NOTICE) &&
((level & APLOG_LEVELMASK) > DEFAULT_LOGLEVEL))
return;
Since DEFAULT_LOGLEVEL is defined [in http_log.h] to be APLOG_WARNING (== 4),
and we're calling log_error_core() with s==NULL and level==APLOG_DEBUG(== 7),
log_error_core() returns immediately without actually logging the message.
>How-To-Repeat:
Put these lines into httpd.conf (in this order):
LogLevel debug
LoadModule hello_module libexec/mod_hello.so
[where mod_hello.so is the one supplied with the O'Reilly "Writing Apache
Modules" book]
