[Macports] Error in running tests: `Failure ('test-board_folder.R:1:1'): cached data is read-only: fs::file_access(path, "write") is not FALSE`

[barracuda156]

This is pretty likely it is our bug in Macports and not pins bug. Please feel free to close the issue in such a case, but an advice is still appreciated.

I am not familiar with Macports, so it might be helpful to give me a bit of info on how this code may be running in your situation. The test that is failing is equivalent to this:

library(pins)
b <- board_temp()
b |> pin_write(1:10, "nice-numbers")
#> Guessing `type = 'rds'`
#> Creating new version '20240417T175854Z-709c5'
#> Writing to pin 'nice-numbers'
path <- pin_download(b, "nice-numbers")

## can I write to this path?
fs::file_access(path, "write")
#> /var/folders/hv/hzsmmyk9393_m7q3nscx1slc0000gn/T/RtmpuGG5Mi/pins-abf8acf40f6/nice-numbers/20240417T175854Z-709c5/nice-numbers.rds 
#>                                                                                                                             FALSE
fs::file_info(path)$permissions
#> [1] r--r--r--

^{Created on 2024-04-17 with reprex v2.1.0}

Here, notice that I do not have permission to write to that path. This is because when the pin is written, we set the permissions:

https://github.com/rstudio/pins-r/blob/b8827ac2d61cda526d01a9a4db57af4d4108bceb/R/board_folder.R#L82

Seems like something unusual may be going on with how your setup deals with the filesystem?
