Probably not enough consensus for a mass edit. Best we can do is case-by-case fixes reading warn reports.

(re-opening, there's more work left here)

On it, thank you!

My friend, I think you are affected by this change, and this applies to whatever PHP version

I'm on the latest pull, commit f81e821abf2b275d1778d02a018a4d0af7208be8.
A bit off topic here :) but I'll quickly sum up the issue I'm having (and am in the middle of trying things to fix):

• Visiting https://[phorge instance]/auth/config/view/2/, where my Github auth item is, makes nginx dump a blank 502 page, no further info.
• First instinct is to check the /var/log/nginx/error.log, where I get a PHP stack trace concatenated into one line, and an nginx header length error (reformatted for readability. the PHP error is truncated):

Oh, totally possible that I forgot to update it :)

I'll take your word on it that it's supported, though the current installation guide says otherwise.
Further, I had a few roadbumps on a fresh install to a new server with PHP 8, that I suspect may relate to strlen(NULL) behavior, but I did need to set up PHP 7 to make sure that was or wasn't the case.
(I'm in the process of reproducing those and working out a possible cause or trace. Some manifested as warning banners, one as a 502 on my end in the GitHub auth provider.)

We already support PHP 8...

Partially related, a systemd unit for the SSH server. Proposal in D25497

While it could be nice to have this, in the meanwhile I think that having something minimal like D25434 would be nice

I'm Valerio, a simple person: I see "GNU/Linux" and I say "yeah, land".

This is a nice contribution and definitely would be a valuable addition to the docs, IMO.

I honestly have nothing more to be done here. I would like to set as resolved but there are sub-tasks opened

Note that I like to do NOT mention the stuff phutil_nonempty_stringlike() since it causes extra headaches with incoming objects to many friends. Same for its friend phutil_nonempty_scalar() since it's broken with known scalars (T15239).

avoid unuseful tables

mention the cast thing

mention the cast thing

Basically phutil_nonempty_scalar() cannot be used since, instead of returning false when receiving false, it explodes.
