      Implements a variable deposit base calculation for EPM signed submissions (#1547) · 614aa31b
      Gonçalo Pestana authored 
      **Note**: This is a lift-and-shift PR from the old substrate and
polkadot repos, both PRs have been reviewed and audited
(https://github.com/paritytech/substrate/pull/13983,
https://github.com/paritytech/polkadot/pull/7140)

This PR implements a generic `BaseDeposit` calculation for signed
submissions, based on the size of the submission queue.

It adds a new associated type to EPM's config, `type SignedDepositBase`,
that implements `Convert<usize, BalanceOf<T>>`, which is used to
calculate the base deposit for signed submissions based on the size of
the signed submissions queue.

`struct GeometricDepositBase<Balance, Fixed, Inc>` implements the
convert trait so that the deposit value increases as a geometric
progression. The deposit base is calculated by `deposit_base =
fixed_deposit_base * (1 + increase_factor)^n`, where `n` is the term of
the progression (i.e. the number of signed submissions in the queue).
`Fixed` and `Inc` generic params are getters for `Balance` and
`IncreaseFactor` to compute the geometric progression. If
`IncreaseFactor = 0`, then the signed deposit is constant and equal to
`Fixed` regardless of the size of the queue.

### Runtime configs

In Kusama, the progression with 10% increase without changing the
current signed fixed deposit is: (term == size of the queue)

Term 1: `1,333,333,332,000`
Term 2: `1,333,333,332,000 * 1.10 = 1,466,666,665,200`
Term 3: `1,333,333,332,000 * 1.10^2 = 1,613,333,331,200`
Term 4: `1,333,333,332,000 * 1.10^3 = 1,774,666,664,320`
Term 5: `1,333,333,332,000 * 1.10^4 = 1,952,133,330,752`
Term 6: `1,333,333,332,000 * 1.10^5 = 2,147,346,663,827.20`
Term 7: `1,333,333,332,000 * 1.10^6 = 2,362,081,330,210.92`
Term 8: `1,333,333,332,000 * 1.10^7 = 2,598,289,463,231.01`
Term 9: `1,333,333,332,000 * 1.10^8 = 2,858,118,409,554.11`
Term 10: `1,333,333,332,000 * 1.10^9 = 3,143,930,250,509.52`

Westend:

Term 1: `2,000,000,000,000`
Term 2: `2,000,000,000,000 * 1.10 = 2,200,000,000,000`
Term 3: `2,000,000,000,000 * 1.10^2 = 2,420,000,000,000`
Term 4: `2,000,000,000,000 * 1.10^3 = 2,662,000,000,000`
Term 5: `2,000,000,000,000 * 1.10^4 = 2,928,200,000,000`
Term 6: `2,000,000,000,000 * 1.10^5 = 3,221,020,000,000`
Term 7: `2,000,000,000,000 * 1.10^6 = 3,543,122,000,000`
Term 8: `2,000,000,000,000 * 1.10^7 = 3,897,434,200,000`
Term 9: `2,000,000,000,000 * 1.10^8 = 4,287,177,620,000`
Term 10: `2,000,000,000,000 * 1.10^9 = 4,715,895,382,000`

and in Polkadot, the deposit increase is disabled in the current state
of the PR, as the increase factor is 0% -- so nothing changes from the
current behaviour.

      [improve docs] Example pallet crate and Basic Example pallet (#1546) · 1d5a9d25
      Sacha Lansky authored 
      This fixes the broken links in the crate level documentation of the
Examples crate. It also updates the documentation for the Basic Example
pallet by removing the template for documenting a pallet (we now have
[this](https://github.com/paritytech/polkadot-sdk/blob/master/docs/DOCUMENTATION_GUIDELINE.md)
to refer to instead).

Note: I found it unnecessary to provide a link to the doc guidelines as
I don't think this would be where someone should discover them. I also
want to flag some ideas that came while making these minor improvements
in [this
issue](https://github.com/paritytech/polkadot-sdk-docs/issues/27) (for a
subsequent PR) as part of ongoing docs work.

      Executor: Remove `LegacyInstanceReuse` strategy (#1486) · e3899880
      yjh authored 
      

It seems the old strategy have been depracted more than one year. 
So maybe it's time to clean up old strategy for wasm executor.
