bug#42601: Guix install bug: error: Unbound variable: ~S

[Jan Wielkiewicz]

Hello,

I made a package named "qmk-cli" and it seems Guix doesn't like it.
Running "./pre-inst-env guix install "qmk-cli"" results in this:
guix install: error: Unbound variable: ~S

It seems it's not about the name, but the package - I changed the name
to "qmk" and it still doesn't work. Not that this is an excuse for
writing such a strange message.

Make output:

I think some interface changed elsewhere in the codebase and these
errors are confusing. Try `make clean-go && make` before using the
./pre-inst-env script again.

What is the actual diff?  I see that (gnu packages hardware) does not
import (gnu packages avr), so it’s expected that “avr-toolchain” cannot
be found.

Just added it and I get the same result. Anyway, the error message is
useless. I'll try removing some inputs and check what causes this.

Okay, I tested it and it fails on "avr-toolchain", even though I have
#:use-module (gnu packages avr).

“avr-toolchain” is a procedure, not a package.  Use “avr-toolchain-4.9”
or “avr-toolchain-5”.

Success!

What about the strange message though?
"incorrect package definition" would be better.

“Unbound variable: ~S” looks like a format string with a placeholder
that didn’t get replaced with an actual value.  It would be marginally
better if it said “Unbound variable: avr-toolchain”.

We should, I think, take advantage of the fact that the type of inputs
is known: it can only be an origin or a package value.  Perhaps we can
catch unbound variables in inputs and print a more valuable error
message.

The reason I suggested an interface change being responsible for
"Unbound variable: ~S" is that I noticed it a couple days ago after
changes to (guix ui), and it was fixed by `make clean-go`:

http://logs.guix.gnu.org/guix/2020-07-27.log#015055

I think that error message is an example of what can go wrong when using
a development environment without rebuilding everything first.

I suspect there are also bugs lurking in the exception-reporting chain between
a (throw 'exception args ...) and the ultimate format statement that produces
a message with "~S" in it. Perhaps one got fixed or avoided in the upgrade?

It seems like something must receive a malformed (key . args) pair
where the args don't match the standard(?) tuple expected for the key.

I'd look for dynamic format string generation splitting arg strings
and mistakenly recomposing a format string and args for it, such that
"~S" got placed in the arg list instead of string-appended into the
proper final format.

Just a hunch. IIRC I've seen mangling the final format string and its args
wind up with a mismatch in number of args and interpolation "~s" elements
and if not papered over, that gets reported as a formatting error (which it is,
but which hides the real error).

I think you are right.
And all implicit meta-data should be seen as potential security vulnerabilities IMO :)
Who do you trust to do a reinterpret-cast for you?

That would be my hunch too!  I had reported and tried to fix such problems
here: http://issues.guix.gnu.org/41956.  Still unresolved, it requires
more effort to be fixed properly (writing tests mostly).

My bad, I believe this is fixed by

Thanks for reporting the issue!

Is this bug closed, though?

Hello,

I believe there's still something wrong here.
The bug (the new one, described below) occurs after adding 
#:use-module (gnu packages avr) to the firmware.scm file.
Attached the diff file of my package below.

I'm packaging qmk-firmware and here's what happens running guix build:
