Restoring Cache : Failling to unarchive cache

[josh-deprogram]

Hitting problems when trying to rerun a build. the pre Yarn install step of Restoring the Cache is failing, is there a way around skipping this step,

Orb version

Expected behavior

Use previous cache and carry on with the Yarn install

[vonovak]

@Naturalclar I see you recently touched this in https://github.com/react-native-community/react-native-circleci-orb/pull/59. On what type of runner were you experiencing the problems (mac/linux)?. Any idea what can be wrong? I'm also seeing this, on a mac runner. Thanks.

[azizhk]

Started getting this error as well. Orb version: 4.4.2

[mtt87]

Confirm it's happening on 4.4.2 only on Mac environment for me

[mtt87]

Some more info, in my case it says

Found a cache from build 559 at yarn-cache-arch1-darwin-amd64-6_58-...

But I'm now at build 592, is there a way to say if restoring the cache goes wrong then ignore it and install everything from scratch?

[mtt87]

After reading this https://support.circleci.com/hc/en-us/articles/115015426888-Clear-project-dependency-cache I set an environment variable CACHE_VERSION with value v2 and it seems like it solved the issue.

[chrisbruford]

@mtt87 when you first set it, you have changed the comparitor and so it won't be able to find a valid cache to use...thus it creates a new one and everything works.

I found that on the next attempt to build it will use your value v2 and find a matching cache, try to unarchive it and you'll get the same error as before.

[mtt87]

Damn, that's a good point I'll try again soon to verify if it still happening.

Have you tried to downgrade to 3.2.2 to see if it works?

[chrisbruford]

Yes - we downgraded and await a fix to this

[MateusAndrade]

Facing the same issue on xcode: 11.5.0 orb 4.4.2, solved running a simple yarn install --frozen-lockfile --non-interactive since I don't need to cache this folder at a specific step.

[simba-joe]

Seeing this issue as well with 4.4.2

[troZee]

Facing the same issue here: https://app.circleci.com/pipelines/github/react-native-community/react-native-viewpager/296/workflows/f47a2400-fc43-4aec-aedd-a3cafb80ed3e/jobs/972

in this PR: https://github.com/react-native-community/react-native-viewpager/pull/201

[mtt87]

Latest working version for me it's 4.2.2 FYI in case you wanna downgrade

[troZee]

The same for 4.2.2 https://app.circleci.com/pipelines/github/react-native-community/react-native-viewpager/302/workflows/f9554c1e-5dd8-4f27-ac8c-9745aae7e63c/jobs/993

Android works fine, but iOS does not work.

[mtt87]

Add an env variable to your project if you don't already have it CACHE_VERSION and use 2, or if you already have it, increase it. I remember this fixed it for me with 4.2.2 and it still works today

[jdewells]

We're finding that we need to change the CACHE_VERSION for every run, and so far we've only found a way to do it manually by changing the project settings.

With version 4.4.2 I have the same experience with the rn/ios_build job. I set all of this up with Android weeks ago, and the save/restore from cache has been flawless. Setting up the iOS side has been more of a pain.

Here is how we are using the rn orb's job in our workflow. It mostly matches the examples in the documentation (some names withheld to protect the innocent):

- rn/ios_build:
    build_configuration: Debug
    detox_configuration: ios.sim.staging
    device: iPhone 11 Pro
    name: build_ios_debug
    node_version: '12.18'
    project_path: ios/ProjectName.xcworkspace
    project_type: workspace
    scheme: ProjectName-staging
    start_metro: true
    requires:
      - analyze_js
      # ↑ We changed that to the American spelling :) 🇺🇸

1. The build fails with an error like this:

2. We go to the Circle CI environment variables, remove the CACHE_VERSION, and then add new variable with the same name but an incremented value.
   • e.g., remove CACHE_VERSION with value of v2 and add CACHE_VERSION with a value of v3
   • example url for Circle Environment Variables – https://app.circleci.com/settings/project/github/your-org-name/your-repo-name/environment-variables

The cache is successfully restored on the next run, but will fail on subsequent runs. It seems like the restore from cache has somehow changed on a macos executor.

Next steps for me

My next steps are to use the individual commands from the rn orb mixed in with my own save/restore cache commands, though I would love to use the orb here instead!

[donatoaguirre24]

Hi guys! Did any found a solution or workaround to this issue?

[dedan]

I'm also still running into the same issue

[airtonix]

Looking into this.

We had to make the swissknife and react-native orbs local to our setup (we have unoffical orbs disabled).

But this means I can make changes!

So, investigating leads me to these links:

• https://circleci.com/docs/2.0/caching/#yarn-node
• https://circleci.com/docs/2.0/yarn/
  • outcome: don't use /tmp/yarn for the cache, it might be on a different FS that doesn't treat symlinks as you might expect.

The other thing I noticed was that for monorepos, caching will need to be more nuanced:

• https://www.benpickles.com/articles/77-caching-yarn-workspaces-on-circleci

• https://discuss.circleci.com/t/list-parameter-type/26705/6

@m2mathew Appreciate the detailed explanation. I am very new to Circle CI and I couldn't for the life of me figure out how to set environment variables, for those having the same issue as me, i.e. where the hell do you set CACHE_VERSION, as Mathew suggested, it is in the Circle CI UI and here is the link:

[lukebrandonfarrell]

@airtonix Would you mind sharing your "swissknife and react-native orbs local to our setup" approach ?

[Jose4gg]

Hi, I'm dealing with this issue, and I have to change the CACHE_VERSION almost every new PR, do we have a better workaround to fix this bug in the meantime?

This is still happening, v5.0.0 on the rn/ios_build step.

My config at this step:

- rn/ios_build:
      name: build_ios_release
      project_path: ios/MyApp.xcodeproj
      device: "iPhone 12"
      build_configuration: Release

I've opened a potential PR for this.

[vonovak]

Hello, I talked with Matt and he does not have time for OSS so he likely won't be responsive in this repo going forward. While I'm also reducing my free time that I spend with open source, I will be available here to review and merge pull requests.

regarding this issue, I believe it was caused by https://github.com/react-native-community/react-native-circleci-orb/pull/59

The solution is that someone who is bothered by this issue should investigate the proper fix and contribute a PR. Thank you for your understanding! 🙂

[matt-oakes]

Thanks for the message @vonovak! It's true that I'll likely be stepping back for this a bit more and I'm happy for any help that anyone can provide on this.

Seeing as this is a common issue, and I had a spare half hour, I've implemented a workaround to allow you to disable caching using parameters on the commands and jobs. Details are in this commit and it's released in v5.1.0.

This is only a workaround to allow you to move forward with no cache, but I agree that someone who's experiencing this issue should look into a proper fix which allows the cache to be kept there as it can vastly speed up build times.

[gretzky]

Thanks @matt-oakes and @vonovak for the quick response. Being able to disable the cache will definitely help for now. I've submitted a fix (#88), however I'm not entirely sure this a full fix, but it does allow the caches to be used.

[ronwsmith]

I submitted PR #103 which made it into orb version 5.4.0. This allows you to undo the pathing change that seemed to have introduced this issue. You can achieve that by using yarn_cache_folder: ~/.cache/yarn in the ios_build or ios_build_and_test jobs.

I've run my build several times with this config change and haven't run into the permissions issue that drove that breaking change initially.

As a note for anyone planning on utilising this new yarn_cache_folder, just be aware that changing to the orb v5.4.0 and adding the new cache param above may still match the old location /tmp/yarn if there exists a matching checksum (I just had this) - I just chose to upgrade a package I was already planning on upgrading anyway, so they stopped matching and now the restore goes through perfectly!

Thanks @ronwsmith - this was a real pain point when i got the orb setup a few months ago lol

[bionara]

Any update on this? getting the same error now.
