[Koha-devel] Thoughts on reloading Koha plugins

[dcook at prosentient.com.au]

Hi all,

 

It seems to me that installing Koha plugins is easy enough. Each Starman
process will load the plugin into memory because it hasn't seen it before. 

 

However, if you're updating/upgrading a plugin, each Starman process has
already loaded it, so it won't know that it needs to reload it. I think most
of us work around this at the moment either by restarting Plack or just
letting the Starman workers die and be replaced by new ones that use the
updated code. But that doesn't seem optimal for an environment that allows
user plugins.

 

That said,
https://advent.plackperl.org/2009/12/day-4-reloading-applications.html and
https://metacpan.org/pod/Module::Reload have a few points on how reloading
code in a persistent process is a good way to get bugs. 

 

I recall Kyle saying Wordpress was his inspiration for the plugins. I'm
curious how Wordpress handles plugin upgrades.
