lcdsmao commented 3 years ago

Before creating a bug report please make check the following

[x] You have read our FAQ
[x] If you have used flutter. Please install correctly, run pub cache repair. Close the terminal and try again.
[x] If you are on Windows. Make sure you are running the terminal as administrator or with developer permissions.
[x] Run fvm doctor if possible and add the output to the issue.

Describe the bug

Cannot use melos to execute fvm command concurrently.

To Reproduce Steps to reproduce the behavior:

Go to terminal, cd to a mono repo with multiple packages (e.g. melos repo)
Run melos exec -- exec fvm flutter
Check output

See error

Logs Please provide the verbose logs by running --verbose after the command.

Desktop (please complete the following information):

OS: [e.g. iOS]
FVM Version [e.g. 22] 2.0.4
If Windows: Which Powershell are you using?

Additional context

I have tried the same command with fvm 2.0.1 and there is no problem.

leoafarias commented 3 years ago

@lcdsmao I believe this has been solved on version 2.0.4 of FVM, and its a duplicate of this https://github.com/leoafarias/fvm/issues/285

lcdsmao commented 3 years ago

Hi @leoafarias! The fix of #285 has been released with fvm 2.0.3. Currently, I am using fvm 2.0.4 and still have the error. Maybe this problem is different with #285?

leoafarias commented 3 years ago

@lcdsmao Can you run fvm flutter --verbose where the fvm config is?

lcdsmao commented 3 years ago

$fvm flutter --verbose

Manage your Flutter app development.

Common commands:

  flutter create <output directory>
    Create a new Flutter project in the specified directory.

  flutter run [options]
    Run your Flutter application on an attached device or in an emulator.

Usage: flutter <command> [arguments]

Global options:
-h, --help                      Print this usage information.
-v, --verbose                   Noisy logging, including all shell commands executed.
                                If used with --help, shows hidden options.
    --quiet                     Reduce the amount of output from some commands.
    --[no-]wrap                 Toggles output word wrapping, regardless of whether or not the output is a terminal.
                                (defaults to on)
    --wrap-column               Sets the output wrap column. If not set, uses the width of the terminal. No wrapping occurs if not writing to a terminal. Use --no-wrap to turn off wrapping when connected to a terminal.
-d, --device-id                 Target device id or name (prefixes allowed).
    --version                   Reports the version of this tool.
    --machine                   When used with the --version flag, outputs the information using JSON.
    --[no-]color                Whether to use terminal colors (requires support for ANSI escape sequences).
                                (defaults to on)
    --[no-]version-check        Allow Flutter to check for updates when this command runs.
                                (defaults to on)
    --suppress-analytics        Suppress analytics reporting when this command runs.
    --packages                  Path to your "package_config.json" file.

Local build selection options (not normally required):
    --local-engine-src-path     Path to your engine src directory, if you are building Flutter locally.
                                Defaults to $FLUTTER_ENGINE if set, otherwise defaults to the path given in your pubspec.yaml dependency_overrides for sky_engine, if any.
    --local-engine              Name of a build output within the engine out directory, if you are building Flutter locally.
                                Use this to select a specific version of the engine if you have built multiple engine targets.
                                This path is relative to --local-engine-src-path/out.

Options for testing the "flutter" tool itself:
    --show-test-device          List the special 'flutter-tester' device in device listings. This headless device is used to
                                test Flutter tooling.
    --show-web-server-device    List the special 'web-server' device in device listings. 

Available commands:
  analyze           Analyze the project's Dart code.
  assemble          Assemble and build Flutter resources.
  attach            Attach to a running app.
  bash-completion   Output command line shell completion setup scripts.
  build             Build an executable app or install bundle.
  channel           List or switch Flutter channels.
  clean             Delete the build/ and .dart_tool/ directories.
  config            Configure Flutter settings.
  create            Create a new Flutter project.
  daemon            Run a persistent, JSON-RPC based server to communicate with devices.
  devices           List all connected devices.
  doctor            Show information about the installed tooling.
  downgrade         Downgrade Flutter to the last active version for the current channel.
  drive             Run integration tests for the project on an attached device or emulator.
  emulators         List, launch and create emulators.
  format            Format one or more Dart files.
  gen-l10n          Generate localizations for the current project.
  install           Install a Flutter app on an attached device.
  logs              Show log output for running Flutter apps.
  precache          Populate the Flutter tool's cache of binary artifacts.
  pub               Commands for managing Flutter packages.

leoafarias commented 3 years ago

@lcdsmao thanks, can you also run melos exec -- exec fvm install --verbose?

Also, what are you trying to do with melos exec -- exec fvm flutter?

I am creating a melos sample env.

$ melos exec

       └> SUCCESS

When running melos exec -- exec fvm install --verbose, it can randomly fail with the error I posted.

what are you trying to do with melos exec -- exec fvm flutter

Like fvm flutter pub get, fvm flutter gen-l10n, et al.

Executing melos exec -- exec fvm flutter can also randomly fail.

leoafarias commented 3 years ago

@lcdsmao I am not being able to replicate the problem in my test melos environment.

I have setup the .fvm config within the root of the melos workspace, in packages folder and in the package itself.

Any other information you can think of that you can provide?

lcdsmao commented 3 years ago

I am trying to create a repo to reproduce this problem.

lcdsmao commented 3 years ago

Hi @leoafarias I created a project which can reproduce this problem. https://github.com/lcdsmao/bug-melos-fvm Could you try it?

leoafarias commented 3 years ago

@lcdsmao just tried and it seems to be working...

can you run the following command and give the output?

melos exec -- exec fvm doctor

lcdsmao commented 3 years ago

~Weird. I cannot reproduce it now...😅 But this error actually has occurred in our CI. I will try this again tomorrow. If there is any further information, I will comment on this issue. Thank you!~

@lcdsmao Ok good news I can replicate the issue. I will take a look and update you

leoafarias commented 3 years ago

@lcdsmao thanks for your help, race conditions are always a tough one. https://github.com/leoafarias/fvm/actions/runs/857277399 Should be live soon 2.0.5

lcdsmao commented 3 years ago

@leoafarias Thanks for your hard work! I can confirm 2.0.5 works fine now.

dryprogrammer commented 3 years ago

This error took me 7 hours to fix. The race condition left a dummy file. I had to delete ~/fvm

ubuntu:~$ ls -al fvm
-rw-rw-r-- 1 ubuntu ubuntu 0  5 31 13:48 fvm

ubuntu@ubuntu:~$ fvm --version
2.0.5
