Re: [racket-users] Can I somehow connect to and update values in a specific hash table used by a running web server?

The other advice here is good and could help to implement a more principled solution. But, if you want to do something equivalent to editing a running application's database on the fly, just using Racket values instead of a DB, I would build on `file-box`: https://docs.racket-lang.org/web-server/st

You can probably use `make-threshold-LRU-manager ` with a much higher memory threshold than the default from `serve/servlet`, which is about 1

Thanks! It really is a bug in `scheme_get_long_long_val`, where the extraction can read past the end of a bignum on a 32-bit platform. Repair pushed. Great, thank you! Given that I do not normally build Racket, should I wait for the next snapshot from UoU or Northwestern to check out the rep

Thanks George and Matt, those look great. I think I'll try to implement your version later George, as the syntax-parse makes me sure I'll screw up. However it looks like a really nice way to contain what can be changed/updated, while adding things flexibly to it. And it should be possible to combi
