Broken WordPress 6.1 when using FreeBSD FTPD server

The latest WordPress update breaks the FTP server capabilities. )
So don't update to 6.1 yet, because it will break the update possibility of your installation.
And you cannot update anymore after it.

I've created an issue for it (Technically the exists method of the ftpext filesystem always returns true for the default FreeBSD ftpd server)
https://core.trac.wordpress.org/ticket/57063

The coming 6.1.1 version should have reverted this change, but when you already upgraded it's already too late of course ;-)

When you've already installed, to only way forward is to
copy the WordPress 6.0 wp-admin/includeas/class-wp-filesystem-ftpext.php file into the installation.

You can download this 6.0 file here (remove the .txt extension)

Ruby check if gem is loadable

Sometimes you want to only execute a given piece of code if a specific gem has is available. Testing if a constant is defined doesn't aslways work when using autoloading.

Gem.loaded_specs.has_key?('gemname')

Rsync error SuSE when using an old algorithm

Running a rsync command to an old server, specifying a different HostKeyAlgorithm fails very strangely on OpenSuSE

rsync -av --stats --delete '-oHostKeyAlgorithms=+ssh-dss'  root@192.168.1.1:/data/path/ /local/path/
rsync: [Receiver] Failed to exec yAlgorithms=+ssh-dss: No such file or directory (2)
rsync error: error in IPC code (code 14) at pipe.c(85) [Receiver=3.2.3]
rsync: connection unexpectedly closed (0 bytes received so far) [Receiver]
rsync error: error in IPC code (code 14) at io.c(228) [Receiver=3.2.3]

No such file or directory.... IPC code (code 14)
What? 🤔

I don't know exactly what's causing this, but a workaround seems to be to use the -e option and to supply this command to your ssh shell

rsync -av --stats --delete -e "ssh -o HostKeyAlgorithms=+ssh-dss" root@192.168.1.1:/data/path/ /local/path/
