Cypress cannot delete profileDir on exit because it creates files with only read permissions. #31300

ValJed · 2025-03-17T10:06:25Z

Current behavior

Whenever I run tests on a specific browser, I get the linked error when stopping the process.

So pretty clear, it just has no permission to delete some files it created earlier. So I have to do it manually then it works again.

The problem is that even if I change manually the permissions of the entire folder, cypress creates files with only read permission:

~/.config/Cypress/cy/production/browsers/firefox-stable/interactive/CypressExtension

So later, it's unable to delete them.

I'm not sure what I can do to change this behavior. Also I'm wondering why putting these files into .config when it's seems like cache files to me?

Is this problem linked to the fact that I use CYPRESS_RUN_BINARY?

Thanks in advance for any input.

Desired behavior

Cypress should create files with delete permission to be able later to delete them.

Test code to reproduce

Nothing special except I use CYPRESS_RUN_BINARY that runs a binary from nix.

Cypress Version

13.17.0

@ValJed Could you try updating to latest in Firefox and see if this issue still persists? We made a lot of changes to how we interact with Firefox in 14.1.0 and I just want to see if this may already be fixed. Thanks!

ValJed · 2025-03-17T15:57:31Z

@jennifer-shehane Thanks for the quick feedback, cypress 14 is still not available on nix but I'll try as soon as I can.
Note that I have the same issue with chromium (with no clear error in console) but not with electron.

In the case of firefox and chromium I can fix it by manually deleting the content of ~/.config/Cypress/cy/production/browsers/** before to rerun cypress open.

This is very similar to the issue on Windows with the same error message

See Error after running a test using the Firefox browser on the CLI in Windows. #30916 (comment) for repo steps, repeated here for convenience

Reproducible with Cypress 14.2.0 on Windows 11 24H2 with Firefox 136.0.1 and Node.js 22.14.0 LTS

git clone --branch firefox-profile https://github.com/MikeMcC399/cypress-test-tiny
cd cypress-test-tiny
npm ci
./firefox-loop.sh

@ValJed thank you for opening an issue! We currently don't modify the copied extension directory contents except for background.js. I am working on building a Cypress pre-release binary that you and @MikeMcC399 can try that might resolve the issue. Right now its a bit aggresive, but its giving read, write, and execute permissions to the extension directory when we copy it over. Binaries should be available on this commit shortly. Are you both able to give the binary a try?

MikeMcC399 · 2025-03-18T19:07:45Z

@AtofStryker

The beta binary doesn't resolve the issue unfortunately. Perhaps it is a timing issue since in some runs there was no issue, and then in others it failed to delete the profile on exit.

These are my steps:

git clone --branch firefox-profile https://github.com/MikeMcC399/cypress-test-tiny
cd cypress-test-tiny
npm ci
./firefox-loop.sh # fails sporadically
npm install npm install https://cdn.cypress.io/beta/npm/14.2.1/win32-x64/chore/FF-investigation-6286411864a452664012a221430bc3af8e10e0f4/cypress.tgz
./firefox-loop.sh

with logs attached:

@AtofStryker

This original issue from @ValJed is for Nix, which has its own special challenges. My repro is on Windows and on Linux it works fine. I think there are perhaps two related problems, so I'm going to submit a new issue for Windows.

From previous issues, I know that it is difficult for NixOS users to update, so that would be another reason to split the troubleshooting.

MikeMcC399 · 2025-03-19T13:49:21Z

New issue is "[firefox-profile] cannot delete profileDir on exit" sporadic issue on Windows #31324 for Windows.

Windows is showing the following, which is a different errno from the one in this issue (errno: -13)

  errno: -4048,
  code: 'EPERM',
  syscall: 'unlink',

ValJed · 2025-03-20T13:19:45Z

Hey @AtofStryker thanks for your investigation.
I can surely test on my own, I'm not sure the binary is still avaiable on the PR you linked (which is closed now) or I didn't find it.
Let me know, thanks!

You can find the binaries on 6286411#comments

I'm not sure if @AtofStryker is still waiting for feedback on this one though.

@ValJed the binaries would be available in the comments of 6286411#comments. I closed the PR since the binaries built and we need a PR to run CI

ValJed · 2025-03-21T10:28:23Z

@AtofStryker Ok I tried to test but I don't think this is the right binary since it's node code.
As I stated I have cypress globally installed through Nix.

I tried running it with the variable:
CYPRESS_RUN_BINARY=/home/user/Downloads/package/bin/cypress
I got

Could not run binary set by environment variable: CYPRESS_RUN_BINARY=/home/user/Downloads/package/bin/cypress

Ensure the environment variable is a path to the Cypress binary, matching **/Cypress

----------

Platform: linux-x64 (Ubuntu - )
Cypress Version: 13.17.0

I tried simply renaming the binary with a capital C Cypress.

I got

No version of Cypress is installed in: /home/user/Downloads/package/bin

Please reinstall Cypress by running: cypress install

----------


Cannot read binary version from: /home/user/Downloads/package/bin/resources/app/package.json

Platform: linux-x64 (Ubuntu - )
Cypress Version: 13.17.0

MikeMcC399 · 2025-03-21T11:13:10Z

@ValJed

The binaries have the version 14.2.1

npm install https://cdn.cypress.io/beta/npm/14.2.1/linux-x64/chore/FF-investigation-6286411864a452664012a221430bc3af8e10e0f4/cypress.tgz

Unfortunately I don't know if you can directly use this under NixOS, since the Nix organization repackages Cypress. You might need to go through the packaging process to integrate the binary I guess.

It looks like you are using Cypress 13.17.0 from the nixpkgs so-called unstable release.
