That’s interesting, Galen.
If I recall correctly, loading libraries in PHP doesn’t load them into PHP per se but rather inserts the code into the PHP script itself. I suppose in that way maybe you could cache and invalidate individual scripts and not have to worry about “unloading modules”. I don’t think we have any equivalent in Perl though, unfortunately. With Plack, we have Plack::App::CGIBin, which caches CGI scripts by turning them into packages, but everything is living in that Starman worker process. I have to go into a meeting but more thinking to do here… David Cook Software Engineer Prosentient Systems Suite 7.03 6a Glen St Milsons Point NSW 2061 Australia Office: 02 9212 0899 Online: 02 8005 0595 From: Galen Charlton <g...@equinoxoli.org> Sent: Thursday, 27 May 2021 3:59 AM To: David Cook <dc...@prosentient.com.au> Cc: Arthur <arthur.suz...@biblibre.com>; koha-devel <koha-devel@lists.koha-community.org> Subject: Re: [Koha-devel] Thoughts on reloading Koha plugins Hi, On Wed, May 26, 2021 at 1:17 AM <dc...@prosentient.com.au <mailto:dc...@prosentient.com.au> > wrote: Hmm interesting. I see instructions on setting up Wordpress with FastCGI but no comments about any impact that would have on plugins. Maybe they just don’t worry about it the same way most Koha folk don’t worry about it hehe. As I recall, Zend Opcache has various settings to control if and when it will recompile the PHP scripts in caches. Depending on what settings you choose, in a FastCGI environment it can periodically check to see if a script has been updated and update the cache if need be - or, if you choose, never revalidate the cache, in which case you'd need to reload or restart php-fpm after changing code. Also, WordPress has code that tries to clear opcache.
