Prior to this PR, the e2e tests where creating dirs like:
```
/tmp/testname1.etcd030299846
/tmp/testname0.etcd039445123
/tmp/testname0.etcd206372065
```
and not cleaning them, that led to disk-space-exceeded flakes.
After the PR, the testing.TB tempdir mechanism is used and the names are
being cleaned and are more miningful:
```
../../bin/etcd --name test-TestCtlV3EndpointHashKV-2 --listen-client-urls http://localhost:20010 --advertise-client-urls http://localhost:20010 --listen-peer-urls https://localhost:20011 --initial-advertise-peer-urls https://localhost:20011 --initial-cluster-token new --data-dir /tmp/TestCtlV3EndpointHashKV429176179/003 --snapshot-count 100000 --experimental-initial-corrupt-check --peer-auto-tls --initial-cluster test-TestCtlV3EndpointHashKV-0=https://localhost:20001,test-TestCtlV3EndpointHashKV-1=https://localhost:20006,test-TestCtlV3EndpointHashKV-2=https://localhost:20011
```
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.
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
- 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
Replace ./scripts/install_tool.sh with `gobin`, such that we have
consistent handling for all tools needed for build and consistent
versioning within ./tools/mod/go.mod.
Side changes:
- Expose /scripts/fix.sh that fixes formatting and bom across modules
- Expose *.sh variants of scripts like build and ./test (first step
towards replacement).
- Make stderr output of commands explicit and make commands use
different color than callouts.
- don't close ready channel until PeerServer is listening.
avoids possible panic in Stop() if PeerServer is nil.
- avoid data race in Run() (err variable was shared between 2 goroutines)
- avoid data race in PeerServer Start/Stop (PeerServer.closeChan)
use the third_party.go project to replace our update script. This
requires moving a few things around and gets rid of a few annoying bugs:
- You can now bump individual packages
- A new src directory isn't created on build
- Less shell scripting!
- Things get built into ./bin/
