Putting these settings in /etc/php/7.2/apache/php.ini did the job:
[XDebug]
xdebug.profiler_enable = 1
xdebug.profiler_output_dir = /tmp/xdebug
xdebug.profiler_output_name = cachegrind.out.%p.%u.%H.%R.xt
The cachegrind files are now written to /tmp/xdebug.
I had an issue with Apache2 improperly serving a JavaScript file which I seem to have fixed by making sure the file was terminated with a new-line character… this was really hard to diagnose and resolve! The behaviour in Firefox was that the file just didn’t finish to download, whereas the Apache2 logs indicated a 200 result… I think it may have had something to do with automatic compression, which is a dark art that I do not understand (mumbles something about mod deflate…).
See here.
Basically, edit /usr/sbin/apache2ctl and in start) add nice:
nice $HTTPD ${APACHE_ARGUMENTS} -k $ARGV
Disabled Apache2 with:
update-rc.d -f apache2 remove
I had a problem with my rewrite rules, that looked like this:
DocumentRoot /var/www/trust.jj5.net
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) http://trust.jj5.net/sorry.html [L,R]
I was trying to redirect any request which didn’t match a file or directory. The !-f and !-d requirements were failing because the path to the REQUEST_FILENAME wasn’t fully qualified. I fixed the problem by including the DOCUMENT_ROOT:
DocumentRoot /var/www/trust.jj5.net
RewriteEngine On
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-f
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-d
RewriteRule (.*) http://trust.jj5.net/sorry.html [L,R]
Happy days! :)
Needed to use the Apache2 NameVirtualHost directive to enable virtual hosts on an IP address for one of my servers. Not entirely sure where the best place to put this configuration directive was I elected to put it in /etc/apache2/httpd.conf — which was empty before hand.
Learned about the Apache2 MaxClients directive which I set in my /etc/apache2/apache2.conf file. To figure out which MPM section to put the setting in I ran:
# apache2 -V | grep MPM
