In addition to the core PHP language components, there are several
sub-transitions needed for the various ecosystems written in the
language. One of these, a web framework called Symfony, is our main
blocker right now; it was stuck in a circular build dependency with
Twig, but that was resolved last week, and now its a matter of sorting
out test and api/abi inconsistencies with Doctrine and various other
packages. We're working actively on this.
Any package mentioning symfony in update_excuses or log files is likely
tied up with the above, and there won't be much to do for them until
symfony is sorted out.
There are also some other PHP packages with unrelated build or test
issues. These are mostly either due to using pre-PHP8 syntax that needs
cleaned up (sometimes there are patches upstream), or dependency issues
with another package that needs updated to PHP 8.
