fix(api-client): default consortium provider timeout test flake #656

petermetz · 2021-03-10T22:15:21Z

Describe the bug

The mentioned test case is flaky because we depend on an external service to simulate certain HTTP status codes for different failure modes.

We need to migrate over to something like this1 to simulate HTTP failure scenarios in-house without having to go beyond the local network interface so that the CI will not depend on external services that can experience downtime (well, we still get this with DockerHub sometimes, but it is what it is...)

To Reproduce

It's a flaky test so it will happen randomly if you try hard enough and for long enough.

Expected behavior

No flaky tests, ever.

Cloud provider or hardware configuration:

Always happens on the Github Actions CI runner.

Operating system name, version, build:

Ubuntu LTS

Hyperledger Cactus release version or commit (git rev-parse --short HEAD):

main

Additional context

This has been worked on before but it seems the earlier fix has failed to deliver on its promises so we have to get back at it again.

FYI @kikoncuo @jagpreetsinghsasan @AzaharaC @jordigiam I believe this will be fixed once the other PRs get merged that resolve the "disk full" issue. For now my working theory that this flake was also caused by that issue, so hopefully all the failing CI checks will turn green soon.

…ledger-cacti#656 Potentially fixing hyperledger-cacti#656. Definitely improves the situation but it is impossible to tell in advance if this will make all the other- wise non-reproducible issues go away. Fingers crossed. This change makes it so that the pullImage(...) method of the Containers utility class will now - by default - retry 6 times if the docker image pulling has failed. The internval between retries is increasing exponentially (power of two) starting from one second as the delay then proceeding to be 2^6 seconds for the final retry (which if also fails then an AbortError is thrown by the underlying pRetry library that is powering the retry mechanism.) For reference, here is a randomly failed CI test execution where the logs show that DockerHub is randomly in- accessible over the network and that's another thing that makes our tests flaky, hence this commit to fix this. https://github.com/hyperledger/cactus/runs/2178802580?check_suite_focus=true#step:8:2448 In case that link goes dead in the future, here's also the actual logs: not ok 60 - packages/cactus-test-cmd-api-server/src/test/typescript/integration/remote-plugin-imports.test.ts # time=25389.665ms --- env: TS_NODE_COMPILER_OPTIONS: '{"jsx":"react"}' file: packages/cactus-test-cmd-api-server/src/test/typescript/integration/remote-plugin-imports.test.ts timeout: 1800000 command: /opt/hostedtoolcache/node/12.13.0/x64/bin/node args: - -r - /home/runner/work/cactus/cactus/node_modules/ts-node/register/index.js - --max-old-space-size=4096 - packages/cactus-test-cmd-api-server/src/test/typescript/integration/remote-plugin-imports.test.ts stdio: - 0 - pipe - 2 cwd: /home/runner/work/cactus/cactus exitCode: 1 ... { # NodeJS API server + Rust plugin work together [2021-03-23T20:45:51.458Z] INFO (VaultTestServer): Created VaultTestServer OK.

Fingers crossed. An attempt to fix the mysterious error in the CI that can be seen at the bottom. Based off of the advice of a fellow internet user as seen here: https://stackoverflow.com/a/61789467 No idea if this will fix the particular error that we are trying to fix or not, but we have to try. The underlying issue seems to be a bug in npm itself, but knowing that doesn't disappear the need to find a workaround so here we go...

Bumping up the test timesouts to a full hour becauase under heavy load the GHA runner seems to be extremely slow, meaning that the fabric tests can take longer than half an hour each despite the fact that these usually take about 5 minutes or less even on the slow GHA runners.
