For example if we have 13 thread but n is 16, the original logic will panic because the chunk_size is not computed correctly. We should ceil both chunk_size and num_chunks to make sure we have same size of iterator of both side.

That's weird. I remember fixing this with @ed255 shortly after I introduced it.

In any case, thanks for the fix Han!

Sync with upstream and halo2curves v0.4.0 (#9)
4870497 
* - Implements `PartialOrd` for `Value<F>`
- Adds a `transpose` method to turn `Value<Result<_>>` into
  `Result<Value<_>>`
- `Expression::identifier()` remove string memory reallocation

* Fix MockProver `assert_verify` panic errors (privacy-scaling-explorations#118)

* fix: Support dynamic lookups in `MockProver::assert_verify`

Since lookups can only be `Fixed` in Halo2-upstream, we need to add
custom suport for the error rendering of dynamic lookups which doesn't
come by default when we rebase to upstream.

This means that now we have to print not only `AdviceQuery` results to
render the `Expression` that is being looked up. But also support
`Instance`, `Advice`, `Challenge` or any other expression types that are
avaliable.

This addresses the rendering issue, renaming also the `table_columns`
variable for `lookup_columns` as the columns do not have the type
`TableColumn` by default as opposite to what happens upstream.

* fix: Don't error and emit empty String for Empty queries

* feat: Add `assert_sarisfied_par` fn to `MockProver`

* fix: Address clippy errors

* chore: Address review comments

* chore: Fix clippy lints

Resolves: privacy-scaling-explorations#116

* Remove partial ordering for value

* Remove transpose

* Parallelize SHPLONK multi-open prover (privacy-scaling-explorations#114)

* feat: parallelize (cpu) shplonk prover

* shplonk: improve `construct_intermediate_sets` using `BTreeSet` and
`BTreeMap` more aggressively

* shplonk: add `Send` and `Sync` to `Query` trait for more parallelization

* fix: ensure the order of the collection of rotation sets is independent
of the values of the opening points

* fix: FailureLocation::find empty-region handling (privacy-scaling-explorations#121)

After working on fixing
privacy-scaling-explorations/zkevm-circuits#1024, a bug was found in the
verification fn of the MockProver which implies that while finding a
FailureLocation, if a Region doesn't contain any rows.

This is fixed by introducing a 2-line solution suggested by @lispc.

Resolves: privacy-scaling-explorations#117

* Feature: Expose Fixed columns & Assembly permutation structs in MockProver instance (privacy-scaling-explorations#123)

* feat: Expose fixed columns in MockProver

* change: Make `Assembly` object public & add getters

* chore: Address leftover TODOs

* Feature to serialize/deserialize KZG params, verifying key, and proving key into uncompressed Montgomery form (privacy-scaling-explorations#111)

* feat: read `VerifyingKey` and `ProvingKey` does not require `params` as
long as we serialize `params.k()`

* feat: add features "serde-raw" and "raw-unchecked" to
serialize/deserialize KZG params, verifying key, and proving key
directly into raw bytes in internal memory format.
So field elements are stored in Montgomery form `a * R (mod p)` and
curve points are stored without compression.

* chore: switch to halo2curves 0.3.1 tag

* feat: add enum `SerdeFormat` for user to select
serialization/deserialization format of curve and field elements

* Add support for Column annotations for MockProver debugging (privacy-scaling-explorations#109)

* feat: Add `name_column` to `Layouter` & `RegionLayouter`

This adds the trait-associated function `name_column` in order to enable
the possibility of the Layouter to store annotations aobut the colums.

This function does nothing for all the trait implementors (V1,
SimpleFloor, Assembly....) except for the `MockProver`. Which is
responsible of storing a map that links within a `Region` index, the
`column::Metadata` to the annotation `String`.

* feta: Update metadata/dbg structs to hold Col->Ann mapping

* feat: Update emitter module to print Column annotations

* feat: Add lookup column annotations

This adds the fn `annotate_lookup_column` for `ConstraintSystem` which
allows to carry annotations for the lookup columns declared for a
circuit within a CS.

* feat: Add Lookup TableColumn annotations

This allows to annotate lookup `TableColumn`s and print it's annotation
within the `assert_satisfied` fn.

This has required to change the `ConstraintSystem::lookup_annotations`
to have keys as `metadata::Column` rather than `usize` as otherwise it's
impossible within the `emitter` scope to distinguish between regular
advice columns (local to the Region) and fixed columns which come from
`TableColumn`s.

* fix: Customly derive PartialEq for metadata::Region

This allows to ignore the annotation map of the metadata::Region so that
is easier to match against `VerifyFailure` errors in tests.

* fix: Update ConstraintNotSatisfied testcase

* fix: Update Debug & Display for VerifyFailure

It was necessary to improve the `prover.verify` output also. To do so,
this required auxiliary types which are obfuscated to any other part of the lib
but that are necessary in order to be able to inject the Column names inside of
the `Column` section itself.
This also required to re-implement manually `Debug` and `Display` for this enum.

This closes zcash#705

* fix: Address clippy & warnings

* fix: Add final comments & polish

* fix: Resolve cherry-pick merge conflics & errors

* chore: Change DebugColumn visibility

* chore: Allow to fetch annotations from metadata

* chore: Fix clippy lints

* chore: Remove comments from code for testing

* feat: Add support for Advice and Instance anns in lookups

* feat: Allow `V1` layouter to annotate columns too

* fix: Support `Constant` & `Selector` for lookup exprs

* chore: Address review comments

* chore: Propagete write! result in `VerifyFailure::Display`

* chore: Address clippy lints

* chore: Move Codecov, wasm-build, Bitrot & doc-tests to push (privacy-scaling-explorations#125)

* chore: Move Codecov, wasm-build, Bitrot & doc-tests to push

This should cut down significantly the CI times on every push done to a
branch for a PR.
Resolves: privacy-scaling-explorations#124

* chore: Add back `push` on CI checks

* fix: Allow to compare `Assembly` structs (privacy-scaling-explorations#126)

This was missing in privacy-scaling-explorations#123 so this PR fixes it.

* Add keccak256 hasher for transcript (#2)

* Add keccak256 hasher for transcript

* Squashed commit of the following:

commit 17e3c4e
Author: Mickey <[email protected]>
Date:   Fri Jul 15 11:10:32 2022 +0800

    speed up generate vk pk with multi-thread

* fix

* Improve performance of vk & pk keygen and of default `parallelize` chunking size.

Reduces proving time on large circuits consistently >=3%.
Builts upon [speed up generate vk pk with multi-thread](privacy-scaling-explorations#88)
Fixes: privacy-scaling-explorations#83

* fix: Force `VerifyFailure` to own the annotations map (privacy-scaling-explorations#131)

* fix: Force `VerifyFailure` to own the annotations map

Since otherwise we can't move the `VerifyFailure` vec's confortably, and
also, we're required to have a lot of lifetime annotations, it was
decided to force the `VerifyFailure` to own the Annotation maps.

This shouldn't be too harmful as it only triggers when testing.

Resolves: privacy-scaling-explorations#130

* chore: Address clippy lints

* feat: call synthesize in `MockProver` multiple times to behave same as real prover

* feat: check advice assignment consistency between different phases

* fix: Support annotations for CellNotAssigned in verify_par (privacy-scaling-explorations#138)

* feat: Add `assert_satisfied_at_rows_par` variant (privacy-scaling-explorations#139)

Resolves: privacy-scaling-explorations#133

* Expose mod `permutation` and re-export `permutation::keygen::Assembly` (privacy-scaling-explorations#149)

* feat: expose mod ule `permutation` and re-export `permutation::keygen::Assembly`

* feat: derive `lone` for `permutation::keygen::Assembly`

* feat: bump MSRV for `inferno`

* feat(MockProver): replace errors by asserts

In MockProver, replace all code that returns an error by an assert that panics instead of returning the error.  This change aims to make it easier to debug circuit code bugs by getting backtraces.

* MockProver test utililities (privacy-scaling-explorations#153)

* test/unwrap_value: escape Value safety in the dev module

* test/mock-prover-values: MockProver exposes the generated columns to tests

* test/mock-prover-values: doc

* mockprover-util: remove unwrap_value

random poly generator inside of `commit`.

Resolves: privacy-scaling-explorations#151

* chore: add `from_evals` for Polynomial

* chore: add benches for commit_zk serial vs par

* fix: Correct thread_seeds iter size

* fix: Clippy

* chore: apply review suggestions

* fix: Inconsisten num of Scalars generated parallely

rounding the num of Scalars to be generated and so, was producing
failures.

* change: Migrate workspace to pasta_curves-0.5 (privacy-scaling-explorations#157)

* change: Migrate workspace to pasta_curves-0.5

This ports the majority of the workspace to the `pasta_curves-0.5.0`
leaving some tricky edge-cases that we need to handle carefully.

* fix: Complete latest trait bounds to compile halo2proofs

* change: Migrate examples & benches to pasta 0.5

* change: Migrate halo2_gadgets to pasta-0.5

* fix: Apply review suggestions

* fix: pin `halo2curves` version to `0.3.2`

* Extend Circuit trait to take parameters in config (privacy-scaling-explorations#168)

* Extend Circuit trait to take parameters in config

The Circuit trait is extended with the following:
```
pub trait Circuit<F: Field> {
    /// [...]
    type Params: Default;

    fn params(&self) -> Self::Params {
        Self::Params::default()
    }

    fn configure_with_params(meta: &mut ConstraintSystem<F>, params: &Self::Params) -> Self::Config {
        Self::configure(meta)
    }

    fn configure(meta: &mut ConstraintSystem<F>) -> Self::Config;
}
```

This allows runtime parametrization of the circuit configuration.  The extension to the Circuit trait has been designed to minimize the breaking change: existing circuits only need to define the associated `type Params`.

Unfortunately "Associated type defaults" are unstable in Rust, otherwise this would be a non-breaking change.  See rust-lang/rust#29661

* Implement circuit params under feature flag

* Don't overwrite configure method

* Fix doc test

* Allow halo2 constraint names to have non static names (privacy-scaling-explorations#156)

* fix: compute `num_chunks` more precisely (privacy-scaling-explorations#172)

* Implement Clone trait for Hash, Absorbing, and Sponge structs (privacy-scaling-explorations#171)

* Revert double-assignment mock prover check

Revert the check introduced in
privacy-scaling-explorations#129 to detect double
assignments with different values, because it breaks some tests in the zkevm
project.

There's a legitimate use case of double assignment with different values, which
is overwriting cells in order to perform negative tests (tests with bad witness
that should not pass the constraints).

Also in the EVM Circuit from the zkevm project we "abuse" the assignment of
cells as a cache: sometimes we assign some cells with a guess value, and later
on we reassign with the correct value.

I believe this check is interesting to have, so we could think of ways to add
it back as an optional feature.
