bug: builds broken with an uncaught composer error

[rhoerr]

I currently get an error on mageos-release:

I've tried various things including updating composer, reinstalling node packages, and updating node packages, but to no avail.

This error appears to affect the upstream mirror builds too, for as long as the action history shows: https://github.com/mage-os/generate-mirror-repo-js/actions/runs/12732736267/job/35488270194#step:8:331

Which makes me wonder if the entire build process is currently broken.

A release build to the preview repo on GitHub worked fine: https://github.com/mage-os/generate-mirror-repo-js/actions/runs/12741163730

I'm not sure what the difference is or why nighties and my local would be affected, but the release action isn't.

[fballiano]

isn't this kinda the same as #171? unfortunately I don't know node enough to help, I guess the only person is @Vinai here :-)

[rhoerr]

Possibly duplicate to #171, but that started about more broad nightly build errors, so I thought it best to open this with my specific issue.

Vinai mentioned this maybe being a composer segfault in a recent meeting. Hopefully he has more insight or ideas on what to try.

[rhoerr]

Okay, so this isn't related to the composer install command, it's actually (shockingly, as the error says) from php-classes.phar, which is called later.

          const classesInDiXml = childProcess.spawn('php-classes.phar', ['--di.xml', 'app/etc/di.xml'], options);

ENOENT means that doesn't exist, which it didn't on my system. This is covered in the readme, so, go me:

Also, the github.com/mage-os/php-dependency-list phar executable is expected to be in the PATH.
curl -L https://github.com/mage-os/php-dependency-list/raw/main/php-classes.phar -o /usr/local/bin/php-classes.phar
chmod +x /usr/local/bin/php-classes.phar

I missed that and must not have run this command on this system before. This is a possible area for improvement.

As for the nightlies, deploy.yml includes a step to download php-classes.phar ("Install PHP source code dependency analyzer and make executable (used by nightly build script for base package)"). That must not be working properly anymore, if the nightly build is hitting this same error.

[rhoerr]

The nightlies error is EPIPE, something entirely different. Closing this as user error. I'll add a better error message for this missing dependency in my PR.
