* Refactor election solution trimming for efficiency
The previous version always trimmed the `CompactOf<T>` instance,
which was intrinsically inefficient: that's a packed data structure,
which is naturally expensive to edit. It's much easier to edit
the unpacked data structures: the `voters` and `assignments` lists.
* rework length-trim tests to work with the new interface
Test suite now compiles. Tests still don't pass because the macro
generating the compact structure still generates `unimplemented!()`
for the actual `compact_length_of` implementation.
* simplify
* add a fuzzer which can validate `Compact::encoded_size_for`
The `Compact` solution type is generated distinctly for each runtime,
and has both three type parameters and a built-in limit to the number
of candidates that each voter can vote for. Finally, they have an
optional `#[compact]` attribute which changes the encoding behavior.
The assignment truncation algorithm we're using depends on the ability
to efficiently and accurately determine how much space a `Compact`
solution will take once encoded.
Together, these two facts imply that simple unit tests are not
sufficient to validate the behavior of `Compact::encoded_size_for`.
This commit adds such a fuzzer. It is designed such that it is possible
to add a new fuzzer to the family by simply adjusting the
`generate_solution_type` macro invocation as desired, and making a
few minor documentation edits.
Of course, the fuzzer still fails for now: the generated implementation
for `encoded_size_for` is still `unimplemented!()`. However, once
the macro is updated appropriately, this fuzzer family should allow
us to gain confidence in the correctness of the generated code.
* Revert "add a fuzzer which can validate `Compact::encoded_size_for`"
This reverts commit 916038790887e64217c6a46e9a6d281386762bfb.
The design of `Compact::encoded_size_for` is flawed. When `#[compact]`
mode is enabled, every integer in the dataset is encoded using run-
length encoding. This means that it is impossible to compute the final
length faster than actually encoding the data structure, because the
encoded length of every field varies with the actual value stored.
Given that we won't be adding that method to the trait, we won't be
needing a fuzzer to validate its performance.
* revert changes to `trait CompactSolution`
If `CompactSolution::encoded_size_for` can't be implemented in the
way that we wanted, there's no point in adding it.
* WIP: restructure trim_assignments_length by actually encoding
This is not as efficient as what we'd hoped for, but it should still
be better than what it's replacing. Overall efficiency of
`fn trim_assignments_length` is now `O(edges * lg assignments.len())`.
* fix compiler errors
* don't sort voters, just assignments
Sorting the `voters` list causes lots of problems; an invariant that
we need to maintain is that an index into the voters list has a stable
meaning.
Luckily, it turns out that there is no need for the assignments list
to correspond to the voters list. That isn't an invariant, though previously
I'd thought that it was.
This simplifies things; we can just leave the voters list alone,
and sort the assignments list the way that is convenient.
* WIP: add `IndexAssignment` type to speed up repeatedly creating `Compact`
Next up: `impl<'a, T> From<&'a [IndexAssignmentOf<T>]> for Compact`,
in the proc-macro which makes `Compact`. Should be a pretty straightforward
adaptation of `from_assignment`.
* Add IndexAssignment and conversion method to CompactSolution
This involves a bit of duplication of types from
`election-provider-multi-phase`; we'll clean those up shortly.
I'm not entirely happy that we had to add a `from_index_assignments`
method to `CompactSolution`, but we couldn't define
`trait CompactSolution: TryFrom<&'a [Self::IndexAssignment]` because
that made trait lookup recursive, and I didn't want to propagate
`CompactSolutionOf<T> + TryFrom<&[IndexAssignmentOf<T>]>` everywhere
that compact solutions are specified.
* use `CompactSolution::from_index_assignment` and clean up dead code
* get rid of `from_index_assignments` in favor of `TryFrom`
* cause `pallet-election-provider-multi-phase` tests to compile successfully
Mostly that's just updating the various test functions to keep track of
refactorings elsewhere, though in a few places we needed to refactor some
test-only helpers as well.
* fix infinite binary search loop
Turns out that moving `low` and `high` into an averager function is a
bad idea, because the averager gets copies of those values, which
of course are never updated. Can't use mutable references, because
we want to read them elsewhere in the code. Just compute the average
directly; life is better that way.
* fix a test failure
* fix the rest of test failures
* remove unguarded subtraction
* fix npos-elections tests compilation
* ensure we use sp_std::vec::Vec in assignments
* add IndexAssignmentOf to sp_npos_elections
* move miner types to `unsigned`
* use stable sort
* rewrap some long comments
* use existing cache instead of building a dedicated stake map
* generalize the TryFrom bound on CompactSolution
* undo adding sp-core dependency
* consume assignments to produce index_assignments
* Add a test of Assignment -> IndexAssignment -> Compact
* fix `IndexAssignmentOf` doc
* move compact test from sp-npos-elections-compact to sp-npos-elections
This means that we can put the mocking parts of that into a proper
mock package, put the test into a test package among other tests.
Having the mocking parts in a mock package enables us to create a
benchmark (which is treated as a separate crate) import them.
* rename assignments -> sorted_assignments
* sort after reducing to avoid potential re-sort issues
* add runtime benchmark, fix critical binary search error
"Why don't you add a benchmark?", he said. "It'll be good practice,
and can help demonstrate that this isn't blowing up the runtime."
He was absolutely right.
The biggest discovery is that adding a parametric benchmark means that
you get a bunch of new test cases, for free. This is excellent, because
those test cases uncovered a binary search bug. Fixing that simplified
that part of the code nicely.
The other nice thing you get from a parametric benchmark is data about
what each parameter does. In this case, `f` is the size factor: what
percent of the votes (by size) should be removed. 0 means that we should
keep everything, 95 means that we should trim down to 5% of original size
or less.

* Use host max log level when initializing the `RuntimeLogger`
This should fix performance problems introduced by logging under certain
circumstances. Before we always called into the host and the host was
doing the log filtering, now as the correct max log level is set, we
don't call into the host for every log line to check if it should be
logged. However, we would still call into the host to determine if
something should be logged when `something=trace` is given as we don't
forward the log targets that are enabled.

Currently there is some implicit requirement on `serde` being present in

* Introduce a "dynamic" block size limit for proposing
This adds support for using a dynamic block size limit per call to
`propose`. This is required for Cumulus/Parachains to always use stay in
the limits of the maximum allowed PoV size.
As described in the docs, the block limit is only checked in the process
of pushing transactions. As we normally do some other operations in
`on_finalize`, it can happen that the block size still grows when there
is some proof being collected (as we do for parachains). This means,
that the given block limit needs to be rather conservative on the actual
value and should not be the upper limit.

* Improve complexity of CompactAssignments::unique_targets
Original implementation was O(n**2). Current impl is O(n log n).
Avoided the original proposed mitigation because it does not retain
the de-duplicating property present in the original implementation.
This implementation does a little more work, but retains that property.
* Explicitly choose sp_std Vec and BTreeSet
Ensures that the macro still works if someone uses it in a context
in which sp_std is not imported or is renamed.
* explicitly use sp_std vectors throughout compact macro
* Add PJR challenge functions
- Updates the PJR check to return a counterexample if one exists
- Adds functions to cheaply check counterexamples
This is in support of off-chain PJR challenges: if a miner discovers
that an accepted election solution does not satisfy PJR, it will be
eligible for substantial rewards. This helps ensure that validator
elections have an absolute quality floor, so even if someone manages
to censor well-behaved solutions to give themselves unfair representation,
we can catch them in the act and penalize them.
* counterexample -> counter_example
* reorganize: high -> low abstraction
* reorganize challenges high -> low abstraction
* add note justifying linear search
* Simplify max_pre_score validation

The timestamp inherent type was up to now just a simple `u64`. This
worked, but doesn't give you that much guarantees at compile time about
the type. This pr changes that by converting this type to a unit type
wrapper, similar to what we have done for `Slot`.
This is required for some future pr that touches quite a lot of the
inherents stuff :)
Besides this unit wrapper type, this pr also moves the `OnTimestampSet`
trait to `frame_support::traits`.
* 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

* 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.
