Status update July 4th

Just wanted to let you know where we are with Lemmy.world.

Issues

As you might have noticed, things still won’t work as desired… we see several issues:

Performance

  • Loading is mostly OK, but sometimes things take forever
  • We (and you) see many 502 errors, resulting in empty pages etc.
  • System load: The server is roughly at 60% cpu usage and around 25GB RAM usage. (That is, if we restart Lemmy every 30 minutes. Else memory will go to 100%)

Bugs

  • Replying to a DM doesn’t seem to work. When hitting reply, you get a box with the original message which you can edit and save (which does nothing)
  • 2FA seems to be a problem for many people. It doesn’t always work as expected.

Troubleshooting

We have many people helping us, with (site) moderation, sysadmin, troubleshooting, advise etc. There currently are 25 people in our Discord, including admins of other servers. In the Sysadmin channel we are with 8 people. We do troubleshooting sessions with these, and sometimes others. One of the Lemmy devs, @nutomic@lemmy.ml is also helping with current issues.

So, all is not yet running smoothly as we hoped, but with all this help we’ll surely get there! Also thank you all for the donations, this helps giving the possibility to use the hardware and tools needed to keep Lemmy.world running!

    Leaking memory is safe

    Rust’s memory safety guarantees make it difficult, but not impossible, to accidentally create memory that is never cleaned up (known as a memory leak). Preventing memory leaks entirely is not one of Rust’s guarantees in the same way that disallowing data races at compile time is, meaning memory leaks are memory safe in Rust. We can see that Rust allows memory leaks by using Rc<T> and RefCell<T>: it’s possible to create references where items refer to each other in a cycle. This creates memory leaks because the reference count of each item in the cycle will never reach 0, and the values will never be dropped.
