<h2>Release 1.40.0</h2>
<h1>Behavior Changes</h1>
<ul>
<li>balancer: client channel no longer connects to idle subchannels that are returned by the pickers; LB policy should call SubConn.Connect instead. (<a href="https://github-redirect.dependabot.com/grpc/grpc-go/issues/4579">#4579</a>)
<ul>
<li>This change is in line with existing documentation stating the balancer must call Connect on idle SubConns in order for them to connect, and is preparation for an upcoming change that transitions SubConns to the idle state when connections are lost.  See <a href="https://pkg.go.dev/google.golang.org/grpc/balancer#SubConn">https://pkg.go.dev/google.golang.org/grpc/balancer#SubConn</a> for more details.</li>

As written, the encoding step unnecessarily made and moved multiple copies of
the encoded representation. Reduce this to a single allocation and encode the
data in-place so that a shift is no longer required.

Also: Add a test to ensure letter digits are capitalized, which was previously not
verified but was expected downstream.

No functional changes.

This is proposed language for the upgrade process about the new custom
reactor/mempool support.

This changes adds a failing test for issue #6660. It achieves this by adding a transaction, starting the `broadcastTxRoutine` in a goroutine and then adding another transaction to the mempool. The `broadcastTxRoutine` can receive the second inserted transaction before `insertTx` returns. In that case, `broadcastTxRoutine` will derefence a nil pointer when referencing the `gossipEl` and panic.

This change aims to keep versions of mockery consistent across developer laptops.

This change adds mockery to the `tools.go` file so that its version can be managed consistently in the `go.mod` file.

Additionally, this change temporarily disables adding mockery's version number to generated files. There is an outstanding issue against the mockery project related to the version string behavior when running from `go get`. I have created a pull request to fix this issue in the mockery project.
see: https://github.com/vektra/mockery/issues/397

Update those break statements inside case clauses that are intended to reach an
enclosing for loop, so that they correctly exit the loop.

The candidate files for this change were located using:

    % staticcheck -checks SA4011 ./... | cut -d: -f-2

This change is intended to preserve the intended semantics of the code, but
since the code as-written did not have its intended effect, some behaviour may
change. Specifically: Some loops may have run longer than they were supposed
to, prior to this change.

In one case I was not able to clearly determine the intended outcome. That case
has been commented but otherwise left as-written.

Fixes #6780.

This is a mostly-automated fixup using Comby (https://comby.dev) to remove 
lexically-obvious redundant error checks. No functional changes are intended.

To reproduce the core change:

    # Collapse redundant error check conditionals
    % comby -in-place 'if err != nil {
       return err
    }
    return nil' 'return err' .go

    # Fold out unnecessary error temporaries
    % comby -in-place ':[spc~^\s*]err :[~:?]= :[any]
       return err' ':[spc]return :[any]' .go

Fixes #6479 and related cases.

This pull request removes the homegrown mocks in `light/provider/mock` in favor of mockery mocks.

Adds a simple benchmark only mock to avoid the overhead of `reflection` that `mockery` incurs.

Follow up from PR: #6740

* test/fuzz: add test to reproduce found fuzz errors

This adds a test for closing the `pqueue` while the `pqueue` contains data that has not yet been dequeued.

This issue was found while debugging #6705 

This test will fail until @cmwaters fix for this condition is merged.

This change does two things:
1. It fixes the json fuzzer to account for receiving array results. Arrays are returned by the rpc server when the input data is an array.
2. Adds a `fuzz_test.go` file and corresponding `testdata` directory containing the failing test case.

This seems like a reasonable way to add and track previous crash issues in our fuzz test cases. The upcoming stdlib go fuzz tool does effectively this automatically.

This change adds additional coverage to the `mConnConnection.TrySendMessage` code path. Adds test to ensure it returns `io.EOF` when closed.

Addresses: #6570

This changes adds an `MempoolError` field to the `ResponseCheckTx`. This will allow clients to understand that their transaction was rejected from the mempool despite passing the ABCI check. 

This change also updates the code to make use of early returns to prevent highly nested code blocks. Namely, it returns when the type assertion fails at the beginning of the method, instead of wrapping the entire method in a large if statement. This has a somewhat large effect on the diff as rendered by github.

The Makefile at the root of the repo [includes](cd19ef244e/Makefile (L61)) the Makefile under the `test` package. This fix removes the target defined in the root Makefile in favor of the included one.

Having looked at our network address parsing and connection code, it
really looks like we're not doing anything on top of what the standard
library is doing (both in terms using `net.ParseIP` and also
`net.Dial`,) and I don't think we need to run the tests 2x the number
of times just to run through different areas of the standard
library. I think most of our users are going to be using IPv4, and
would be down to fully remove this dimension as well, if we find it's
making noise, but for now I think it's fine.
