[TYPO3-core] RFC: Resubmission of feature #1585: Logfile by Request URI + configuration of Empty Referer handling + logline hook

[Michael Stucki]

Hello Ralf,

I suppose there was a typo above. Anyway, can I ask you to keep the
underscores in the keys, so that they are identical with
t3lib_div::getIndpEnv(), just lower-case? (reason 1 is consistancy, and
reason 2 is because I've implemented the similar feature using this key
name for a customer already ;-))

Fine

What is exactly the problem here? Currently an empty referer gets
replaced with a dash, which seems ok to me (also see
http://httpd.apache.org/docs/2.0/en/mod/mod_log_config.html/ and compare
how your Apache logs it).

Additionally, I have a comment on this line:

+								$LogLine.= '
"'.((t3lib_div::getIndpEnv('HTTP_REFERER'))?t3lib_div::getIndpEnv('HTTP_REFERER'):$this->config['config']['stat_apache_emptyReferer']).'"';

It calls the same function twice, which I think should be optimized with
little effort.

> (4) On behalf of Thomas Oppelt: Add a LogLine hook to tslib_fe->statistics():
> TYPO3_CONF_VARS['SC_OPTIONS']['tslib/class.tslib_fe.php']['sys_stat-PreLogClass'][]->createLogLine($LogLine,$this)

Did not check if the functionality works, so this is just about the name
of the hook. "sys_stat" indicates a relationship with the sys_stat
extension. This is ok for the first hook which is already existing
because it is wrapped inside a condition: if (isLoaded('sys_stat')).

I don't have a better suggestion at hand though.

Seen this. And as I mentioned above already, I have made a similar patch
which does the same, and some more things like logging of pages not
found and logging of fe_user names according to Apaches behaviour.

I will send it to you so you can have a look at it, however there is no
dependency with this change here.
