golang-plugins
golang-plugins uses the new plugin feature of Go 1.8 to
implement hot code swapping in Go.
This is highly experimental and just a way for me to learn
how plugins work and what limitations I find.
Run this program and then try editing, adding, or removing
files in the plugins directory.
go run main.go
The entry point to the plugins is the Run function, that
doesn't receive any parameters and returns an error.
Limitations:
- This only works on Linux.
- We poll regularly the plugins directory instead of using fsnotify.
- We recompile every time, even if the code has not changed.
- This causes a continuously growing memory requirement (memory leak?).
Disclaimer
This is not an official Google product (experimental or otherwise), it is just
code that happens to be owned by Google.
