[ixpmanager] Composer / PHP Woes during IXP Manager Update

[Ian Chilton]

Hi,

Just attempting to upgrade to the new 6.2.0 release on our development 
instance of IXP Manager.

Running Ubuntu 20.04 with the ondrej PPA for PHP 8. Have just 
dist-upgraded to update everything.
(deb http://ppa.launchpad.net/ondrej/php/ubuntu focal main)

Trying to run composer, first ran in to this:

ixpmanager at portal:/srv/ixpmanager$ HOME=/srv/ixpmanager composer install 
--no-dev --prefer-dist
Deprecation Notice: Required parameter $path follows optional parameter 
$schema in 
/usr/share/php/JsonSchema/Constraints/UndefinedConstraint.php:62

PHP Fatal error: Uncaught ArgumentCountError: array_merge() does not 
accept unknown named parameters in 
/usr/share/php/Composer/DependencyResolver/DefaultPolicy.php:84

There is an issue here: https://github.com/composer/composer/issues/9097 
- saying it’s fixed in the latest.

root at portal:~# dpkg -l |grep compos
ii composer 1.10.1-1

So I did:
$ wget https://getcomposer.org/download/2.1.12/composer.phar

Which looks better, but then fails with another error:

ixpmanager at portal:/srv/ixpmanager$ HOME=/srv/ixpmanager php 
./composer.phar install --prefer-dist --no-dev

….which it just won’t get past:

./composer.phar install --prefer-dist --no-dev

Searching for MemcachedConnector.php, it’s at:
./vendor/laravel/framework/src/Illuminate/Cache/MemcachedConnector.php

And line 69 is the return statement:

protected function createMemcachedInstance($connectionId)
{
     return empty($connectionId) ? new Memcached : new 
Memcached($connectionId);
}

In fact, this isn’t a composer thing:

ixpmanager at portal:/srv/ixpmanager$ php $IXPROOT/artisan migrate:status

In MemcachedConnector.php line 69:

   Class "Memcached" not found



Oddly I do now notice I’ve got a mix of PHP 8 and 8.1 installed?

root at portal:~# dpkg -l |grep php | grep fpm
ii php8.0-fpm 8.0.12-1+ubuntu20.04.1+deb.sury.org+1 amd64 server-side, 
HTML-embedded scripting language (FPM-CGI binary)

root at portal:~# dpkg -l |grep php | grep memcached
ii php-memcached 3.1.5+2.2.0-10+ubuntu20.04.1+deb.sury.org+3 amd64 
memcached extension module for PHP, uses libmemcached
rc php8.0-memcached 3.1.5+2.2.0-10+ubuntu20.04.1+deb.sury.org+3 amd64 
memcached extension module for PHP, uses libmemcached
ii php8.1-memcached 3.1.5+2.2.0-10+ubuntu20.04.1+deb.sury.org+3 amd64 
memcached extension module for PHP, uses libmemcached

So I did:
apt-get install php8.0-memcache and php8.0-memcached

Now both composer and artisan commands now seem ok again.


So going forward - do people tend to use the distro supplied composer 
(and have you had the same problem?) or pull an up-to-date one?

Any ideas what’s going on with the PHP PPA and why it appears to have 
half transitioned to PHP 8.1?

Thanks,

Ian
