Should we also upgrade this list? https://github.com/nextcloud/server/blob/master/composer.json#L26-L33
I was wondering if it's possible to have this list only once, but I don't know how ^^

composer.json is shipped now I think, so could read it and json_decode() and then access the list?

Problem with this could be that it will prevent composing on servers without the package (e.g. on CI), but well we ultimately rely on it anyway.

I updated the list in composer.json but I am a bit uneasy about parsing composer.json from a setup check, can I leave it like that for the time being?

• CI failure is related

Btw I just installed bcmath and gmp, but the message does not disappear:

The PHP modules "gmp" and/or "bcmath" are not enabled. If you use WebAuthn passwordless authentication, these modules are required.

Do they need to be more configured then just installing? If so we should document/outline this?

But mostlikely unrelated to this PR here

Our documentation about that could be more complete, or give pointers to other documenations: https://docs.nextcloud.com/server/latest/admin_manual/installation/source_installation.html#prerequisites-for-manual-installation

@nickvergessen According to comments on https://www.php.net/manual/en/gmp.installation.php , it either has something to do with reloading apache service, or uncommenting the extension in a php.ini (but be careful there’s one for cli and one for apache from what I recall).

The extensions you talk about are from areWebauthnExtensionsEnabled check, which is not migrated to the new API yet.
But still, it is relevant to this PR that we should link to documentation from php modules setup check when it fails. (and that means we need a relevant documentation page, which is not really the case yet)

[come-nc]

@nickvergessen nextcloud/documentation#11239 something like that would give us a documentation page to link to, what do you think?
The modules part is moved from another page and not changed a lot yet, but if you figure out what was missing in your case we can add it to the page.

[come-nc]

Added links to documentation to admin-php-modules which will need to be added to https://github.com/nextcloud/documentation/blob/master/go.php in a follow up.

Probably the wrong place to ask, but since I see bz2 popping up as missing module after this commit: Does anyone know whether this is really used, even if installed and enabled? I see that it's internally supported here, but I do not see a logic which would e.g. automatically download bz2 instead of gz archives of Nextcloud or apps, if the module is present. Also all apps I checked are offered as gzip archives only. The Nextcloud server is offered as bzip2 archive as well, though.
EDIT: At least the NC updater downloads the zip archive, also after installing+enabling the bz2 module.

Hum I don’t know, I took the recommended list from the documentation.
It is very possible that application in bz2 is a feature which no application use 🤷

I just checked the developer docs:

• https://docs.nextcloud.com/server/stable/developer_manual/app_publishing_maintenance/release_process.html?highlight=tarball#the-release
• https://docs.nextcloud.com/server/stable/developer_manual/app_publishing_maintenance/release_automation.html#github-actions

So the release process docs explicitly say ".tar.gz tarball" and the release workflow example also uses a .tar.gz tarball only. So if .tar.bz2 was a supported alternative, it is at least not documented. Furthermore I do not see much use for bzip2 nowadays, it is slower + lower compression ratio than alternatives like xz, which is the standard/default for Linux (releases), APT (packages + package lists) and many other projects nowadays.

So it makes sense to either remove bzip2 support (and hence the module) from the docs completely, or keep the infrastructure for multiple compression algorithm support (in case it does even work OOTB with bzip2 compressed app tarballs) and document it + by times add xz as another more reasonable alternative (bandwidth/storage wise).

I'll open a new issue about this. Minor importance probably, but I like to keep our project's Nextcloud implementation slim (no useless PHP modules) without users asking/complaining about admin panel warnings.

Same question was raised in nextcloud/docker#1351 (comment) and nextcloud/docker#2118. I'm also interested to sort this out, let me know when you created the issue.

[joshtrichards]

Issue #42342 created for Server w/ summary of issues to hopefully get this addressed once and for all across server,appstore, documentation, and docker. :)
