That's not a problem its more a feature of mod-perl. Don't forget the
code you write gets compiled only once per-apache-process/thread.
The following happens:
apache_ctl restart
1. request
=> handled by apache-child 1
=> (no code loaded) compile code (code_1)
=> execute code
=> produces an error
revoke changes
2. request
=> handled by apache-child 1
=> execute code
=> produces an error
3. request
=> handled by apache-child 2
=> (no code loaded) compile code (code_1)
=> execute code
=> successful
In short child1 and child2 have different versions of code and won't
recompile until you say them to do so.
2 ways out:
- -----------
- - always restart apache when files changed
- - use Apache::Reload/Apache2::Reload
