Debugger shows `<unknown>:Nothing (?)` while debugging frequently
While debugging recently I've noticed that the code panel goes completely blank. Is this normal?
If you'd like a reproduction case clone this branch, run make, and then run dapp debug and select VaultFactoryTest::test_deploy_vault(). After stepping through the trace for a little bit you will notice the code panel go blank:
https://github.com/rari-Capital/vaults/tree/v1
is it blank all the time for this contract? Or just in some sections?
Just some sections.
I get this a lot as well, sometimes in very large blocks.
Similar reproduction steps:
- Clone this repo: https://github.com/tcoulter/sai
- Run
dapp debug - Choose the test
CageTest::testCageExistAfterPeriod()(it happens frequently there, though you'll likely reproduce it with many of these tests) - Press
nto step through until you see the same error as the OP.
From my experience, it seems related to contract creation, as it appears to happen a lot during the non-constructor code related to contract creation. This is only a hunch however.
As a feature request, it'd be great if I could step over anything unknown.
Environment:
- Windows Subsystem for Linux v2 (Ubuntu 20.04.1 LTS)
- dapp 0.33.0
- solc, the solidity compiler commandline interface
- Version: 0.8.6+commit.11564f7e.Linux.g++
- hevm 0.47.0

you can step to the next piece of source code with shift-N, or step forward through the bytecode without entering subcalls with control-n
In the case above, I do use shift-N. When it reaches anything unknown, it steps through the instructions as if I was just pressing N alone.
Edit: I guess I didn't specify that above. Perhaps that's a bug!

yup same. should have specified as well oop 😅
doesn't feel good to be stepping thru things smoothly with N and then hit a 2 second patch of abyss
@MrChico @d-xo bumping because running into this while debugging some complex tests rn and its slowing me down quite a bit heh
Not sure we can do much about the fact that srccode is missing for parts of the code, but we can fix the N and c-n issue
but we can fix the N and c-n issue
yup, thats what i was hoping for 🙏
btw i dont see this issue with c-n, but i do sometimes see with c-p
I’ve been switching tools like Leo switches girlfriends (between multiple projects, mind you), so haven’t gotten back to my dapptools project yet. Once I do I’ll let you know!

hehe i just want the debugger to skip the Nothing (?) screens when stepping thru with shift + N/shift + P
Oops, me too! I somehow thought you were the maintainer looking for more info (I responded via email, so my bad!).
