      Implement PJR checker (#8160) · 781f9087
      Peter Goodspeed-Niklaus authored 
      

* Apply.

* get rid of glob import

* use meaningful generic type name

* pjr_check operates on `Supports` struct used elsewhere

* improve algorithmic complexity of `prepare_pjr_input`

* fix rustdoc warnings

* improve module docs

* typo

* simplify debug assertion

* add test finding the phase-change threshold value for a constructed scenario

* add more threshold scenarios to disambiguate plausible interpretations

* add link to npos paper reference

* docs: staked_assignment -> supports

Co-authored-by: default avatarKian Paimani <[email protected]>

* add utility method for generating npos inputs

* add a fuzzer which asserts that all unbalanced seq_phragmen are PJR

Note that this currently fails. I hope that this can be rectified
by calculating the threshold instead of choosing some arbitrary number.

* assert in all cases, not just debug

* leverage a native solution to choose candidates

* use existing helper methods

* add pjr-check and incorporate into the fuzzer

We should probably have one of the W3F people look at this to ensure
we're not misconstruing any definitions, but this seems like a
fairly straightforward implementation.

* fix compilation errors

* Enable manually setting iteration parameters in single run.

This gives us the ability to reproducably extract cases where
honggfuzz has discovered a panic. For example:

$ cargo run --release --bin phragmen_pjr -- --candidates 569 --voters 100

thread 'main' panicked at 'unbalanced sequential phragmen must satisfy PJR', primitives/npos-elections/fuzzer/src/phragmen_pjr.rs:133:5
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

This is still not adequate proof that seq_phragmen is broken; it could
very well be that our PJR checker is doing the wrong thing, or we've
somehow missed a parameter of interest. Still, it's concerning.

* update comment verbiage for accuracy

* it is valid in PJR for an elected candidate to have 0 support

* Fix phragmen_pjr fuzzer

It turns out that the fundamental problem causing previous implementations
of the fuzzer to fail wasn't in `seq_phragmen` _or_ in `pjr_check`: it was
in the rounding errors introduced in the various conversions between the
internal data representation and the external one.

Fixing the fuzzer is then simply an issue of using the internal representation
and staying in that representation. However, that leaves the issue that
`seq_phragmen` occasionally produces an output which is technically not
PJR due to rounding errors. In the future we will need to add some kind of
"close-enough" threshold. However, that is explicitly out of scope of
this PR.

* restart ci; it appears to be stalled

* use necessary import for no-std

* use a more realistic distribution of voters and candidates

This isn't ideal; more realistic numbers would be about twice these.
However, either case generation or voting has nonlinear execution
time, and doubling these values brings iteration time from ~20s to
~180s. Fuzzing 6x as fast should make up for fuzzing cases half the size.

* identify specifically which PJR check may fail

* move candidate collection comment into correct place

* standard_threshold: use a calculation method which cannot overflow

* Apply suggestions from code review (update comments)

* clarify the effectiveness bounds for t-pjr check

* how to spell "committee"

      Init `RuntimeLogger` automatically for each runtime api call (#8128) · 68390d40
      Bastian Köcher authored 
      

* Init `RuntimeLogger` automatically for each runtime api call

This pr change the runtime api in such a way to always and automatically
enable the `RuntimeLogger`. This enables the user to use `log` or
`tracing` from inside the runtime to create log messages. As logging
introduces some extra code and especially increases the size of the wasm
blob. It is advised to disable all logging completely with
`sp-api/disable-logging` when doing the wasm builds for the on-chain
wasm runtime.

Besides these changes, the pr also brings most of the logging found in
frame to the same format "runtime::*".

* Update frame/im-online/src/lib.rs

Co-authored-by: default avatarGuillaume Thiolliere <[email protected]>

* Update test-utils/runtime/Cargo.toml

* Fix test

* Don't use tracing in the runtime, as we don't support it :D
