fix: FileSystemException: Directory listing failed (activate brick with git on Windows)

[DeMarcoMan]

Hello Felix,

We are using your tool for creating new pages/controllers in our apps and it helps us a lot, but we have an issue on Windows. On macOS we don't have this problem.

Description

We get this exception on WIndows:

FileSystemException: Directory listing failed, path = 'C:/Users/mwildenb/AppData/Local/Mason/Cache/git/rubigo_page_Z2l0QGJpdGJ1Y2tldC5vcmc6ZGFsb3N5L3J1Ymlnb19wYWdlLmdpdA==_e85b222e08c551eec5689f9629e45501bf0
52670\__brick__\lib\pages\{{#snakeCase}}{{page_id}}_{{page_name}}{{\snakeCase}}\{{#snakeCase}}{{page_id}}_{{page_name}}{{\*' (OS Error: The system cannot find the path specified.
, errno = 3)

Steps To Reproduce

1. mason get
2. mason make rubigo_page
3. See error

Mason.yaml This is the mason.yaml:

bricks:
  rubigo_page:
    git:
      url: "git@bitbucket.org:dalosy/rubigo_page.git"
      path: 
      ref: V1.0.0

Additional Context We use the latest mason version: 0.1.0-dev.34

Hi @DeMarcoMan 👋 Thanks for opening an issue!

Can you please provide a link to a minimal reproduction sample? I’m not able to access the bitbucket repository. Thanks!

[DeMarcoMan]

Hi Felix,

The rubigo_page repository is now public so you should be able to test this with the mason.yaml above.

@DeMarcoMan thanks! I'll take a look shortly 👍

Hi, any updates on this?

Hello!

I also encountered this problem and did a little digging. It seems that the cause of the problem is the system's limitation to the maximum path length. It's only 260 characters on Windows 10 by default. In DeMarcoMan's description, the path length was 276 characters. In my case it was a little less - 268, but still the same exception.

FileSystemException: Directory listing failed, path = 'C:/Users/alexa/AppData/Local/Mason/Cache/git/mason_test_Z2l0QGdpdGh1Yi5jb206TGVnZW5kb3Jpay9tYXNvbl90ZXN0LmdpdA==_1be1ea19ef103cf450559df3e363aa32517be9f7/feature\__brick__\{{feature_name.snakeCase()}}\data\cache\{{#with_cache}}{{feature_name.snakeCase()}}_cache.dart{{\*' (OS Error: The system cannot find the path specified. , errno = 3)

I created a public repository with a reproducible example and instructions if it helps. I also tried to solve this problem by allowing long paths in the registry but to no avail. Are there any workarounds other than just shorter names?

@Legendorik @DeMarcoMan Hey guys, did you find any workaround ?

@felangel, is it possible to add this to the application manifest for the mason.exe?

<application xmlns="urn:schemas-microsoft-com:asm.v3">  
    <windowsSettings xmlns:ws2="http://schemas.microsoft.com/SMI/2016/WindowsSettings">  
        <ws2:longPathAware>true</ws2:longPathAware>  
    </windowsSettings> 
</application>  

Together with the registry fix as explained in https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry, it might solve this problem for Win10 and above.

Hi @felangel, this issue probably stalls because of the "Question" label that is attached to it. Can you please have a look at this issue and the comments above? Thanks!

Sorry for the delay! It stalled due to Flutter Forward but I will take a look asap.

We found a workaround by moving the MASON_CACHE folder closer to the root of the drive.

You can set the location of the mason cache folder by defining an environment variable MASON_CACHE that points, for example, to c:\mason_cache.

With this workaround, we can use our bricks again with Windows 🚀. see: feat: let us change the location of $HOME/.mason-cache #402
