after I point the finger to LibreSSL for the memory leak,
I find the leak … in my own code.
Not knowing what else to do,
I thought I would go through my TLS Lua module to make sure I didn't miss anything.
That's when I noticed that I was keeping a reference to a connection so that I can deal with the callbacks from
I was expecting the
__gc() method to clean things up,
but with a (non-weak) reference,
that was never going to happen.
just because you are using a garbage collected language doesn't mean you can't still have memory leaks.
I verified that,
the references were being kept around after the request was finished.
It was then straightforward to fix the issue.
That's not to say that
libtls still isn't leaking memory—it is,
but (it seems) only when you initialize it
(which means it's not as bad).
But I'll know in a day or two if I fixed the leak.
I hope that was it.
