Question

I get this error

Internal error Ticket issued: unrecoverable

When trying to run web2py from https://github.com/web2py/web2py/tree/e1bb2b4556352612a8f0386373d23e49f3e138c4

I am using ubuntu 12.04, and already have web2py 1.99.4. But I want to check the new version. As stated in the repo’s readme, I should just simply run python web2py.py

But, when I start the server, I found internal error.

Below is what I get from the shell:

So, what’s wrong here?

Answer 1

That commit is just broken. If you look at the code, the dbs variable never gets defined, so the close_all_instances function will always fail. There’s a bug report for it: web2py issue #1072

You can apply the patch above yourself, or use my patch-1 branch where I’ve applied the patch (and sent a pull request), or you can use the commit just before the code was broken (231a3e1278), or just wait for it to get fixed in master which I’d assume will happen soon.
