Could not set executable bit for mongod

[fjmorel]

One of my coworkers is encountering this exception when trying to use this library. It's probably something in their environment, but am flagging it just in case.

System.IO.IOException
Could not set executable bit for '{test project path}/bin/Debug/net6.0/runtimes/osx-x64/native/mongodb/bin/mongod'
   at EphemeralMongo.Core.FileSystem.MakeFileExecutable(String path)
   at EphemeralMongo.Core.MongoRunner.RunInternal()
   at EphemeralMongo.Core.MongoRunner.Run(MongoRunnerOptions options)
   at BaseMongoCollectionFixture..ctor() in {project path}/BaseMongoCollectionFixture.cs:line 49

This machine worked fine with the latest Mongo2Go. We're all using .NET 6. They upgraded to the latest version of the SDK just in case. This library is working fine for other developers and in GitHub Actions.

P.S. thanks for putting this out there! MongoDB 6 support in our tests helps us feel confident about code using newer aggregation features.

Thanks for reporting the issue! I'll try to reproduce it on my macbook. For an unknown reason yet, chmod +x is failing.
It might be an option to swallow the error and continue the code execution, I keep you updated.

FYI, Mongo2Go does the same thing (chmod +x, see here and here). The only difference is that Mongo2Go targets mongod from the NuGet package cache directory, whereas EphemeralMongo targets mongod in the build output.

It works now. Here's what we tried:

1. Delete bin/obj folders and rebuild
2. Updated Rider
3. Updated .NET SDK
4. Updated macOS
5. Cloning the repo to new a folder

None of those worked.

However, cloning to a new folder inside ~/Documents/ instead of ~/other folder worked!

I'll close this since it seems to have just been a weird file system permission issue.

Hi @fjmorel the issue is in EphemeralMongo's code. Your coworker used a path with a space, and it was not properly escaped. It does not happen often with Mongo2Go because it usually locates mongod in the nuget package directory - its path does not contain spaces. I'll escape the paths and publish a new version very soon.

It's fixed in 0.1.2
