This is not yet implementation, just API and tests to be filled
with implementation in next CLs,
tracked by: https://github.com/etcd-io/etcd/issues/12652
We propose here 3 packages:
- clientv3/naming/endpoints ->
That is abstraction layer over etcd that allows to write, read &
watch Endpoints information. It's independent from GRPC API. It hides
the storage details.
- clientv3/naming/endpoints/internal ->
That contains the grpc's compatible Update class to preserve the
internal JSON mashalling format.
- clientv3/naming/resolver ->
That implements the GRPC resolver API, such that etcd can be
used for connection.Dial in grpc.
Please see the grpc_naming.md document changes & grpcproxy/cluster.go
new integration, to see how the new abstractions work.
They used to take >10min with coverage, so were causing interrupted
Travis runs.
Know thay fit in 100-150s (together), thanks also to parallel
execution.
- making sure the DRY_RUN mode can finish e2e, so e.g. commits to
local copy of repository are OK in dry-run (while git pushes are NOT).
- better interaction with ./test_lib.sh script.
- more consistent logging
- bringing back s390x architecture that on go 1.14.3 seems to work as
expected.
Change amd64 docker image to use a `-amd64` suffix, consistent with
other architectures. Introduce a multiarch docker manifest list with
the original (no-arch) docker tag.
Fixes#10380
Changes:
- signing tags.
- allows to override BRANCH and REPOSITORY using env variables.
Tested by a release in my private fork:
BRANCH="20201126-ptabor-release" REPOSITORY="git@github.com:ptabor/etcd.git" ./scripts/release 3.5.0-alpha.20
Both have shown great initiatives and dedication to the project's long-term health and community engagement.
I strongly support for their recognition and continued work on the project.

- build & test scripts deprecated. Call *.sh variants.
This will avoid delete the symlinks and get rid of
subtle dependency on 'sed --follow-symlinks' on OsX/BSD sed.
- Fix parameters to mktemp
Example:

```
% (cd server && go vet ./...)

```
The root reason of flakes, was that server was considered as ready to
early.
In particular:

```
was taking 5s. If this was happening concurrently with etcdctl, the
etcdctl could timeout.
The fix, requires servers to report 'ready to serve client requests' to consider them up.
Fixed also some whitelisted 'goroutines'.
The commit ensures that spawned etcdctl processes are "closed",
so they perform proper os wait processing.
This might have contributed to file-descriptor/open-files limit being
exceeded.

Now the caches are dropped if the current users is in sudoers, bot not
in the other cases.
To be honest I don't see the purpose for dropping the caches at all in
the test.
dgrijalva/jwt-go has been abandoned and contains several serious
security issues. Most projects are now switching to the form3tech fork.
See https://snyk.io/vuln/SNYK-GOLANG-GITHUBCOMDGRIJALVAJWTGO-596515 for
