error removeDirectoryRecursive permission denied

[kees Bleijenberg]

I edit the code in Atom, After a few updates I get the error removeDirectoryRecursive.....in the red box. When I cose Atom and I do stack build in cmd.exe I get again:

removeDirectoryRecursive: permission denied (Access is denied.)

If I remove the directory .stack-work and I do stack build again, everything is ok. But not for long. After a few updates of the code the error is back again.

I'am using stack version 1.1.2 on windows 7.

There's only one call to removeDirectoryRecursive I see in the Stack codebase, and that applies for install MSYS2 on Windows, which is probably _not_ relevant to what you're doing right now. Do you have any indication from the logs of what was happening immediately before or after? Can you run with `--verbose` and get more detailed logs? What about upgrading to the latest version of Stack?

I've narrowed down the problem. I only get the problem when I add elm-export to the cabal and yaml file as described in the Installation part of https://github.com/krisajenkins/elm-export

The problem starts in Atom. Maybe the problem is not in stack but in ghc-mod??

That definitely narrows it down, it's a call to `removeDirRecur` in Stack.Config. I don't know what could be causing the permissions issues. Are you able to reproduce it with only Stack? Can you generate a minimal case that demonstrates the issue occurring?

The error message from Stack is always after editting the code in Atom. I'll try to create a testcase. I doubt whether I get an error when editting the code with Notepad++. Reducing to a simpler case seems quit difficult to do.

I'am still not sure if this is a Stack problem. Maybe it is a haskell-ghc-mod problem https://github.com/atom-haskell/haskell-ghc-mod/issues/189 

It is a bit annoying that the error message doesn't tell what file/map is read-only and can't be deleted. I've searched in the directory of the program and its subdirs but nothing is read-only.

The log files in the map logs do not change when I get the error after stack build.

Kees

[Michael Snoyman]

To speed things up more, you could create your own Stack executable with a modified version of the recursive deletion function that provides more information. (I agree, it would be much better if the directory package gave more meaningful error messages.) But I think your suspicion of ghc-mod may be correct.

I've build stack on my own computer (easier then I expected). I replaced the call to removeRecurseDir with myRemoveRecurseDir. In myRemoveRecurseDir is one line: error $ show dir

Then I added to the empty main.hs the line: import Elm. Loaded the project in Atom. Did ctrl+s wthich triggers the building process. I get the error and closed Atom. In a cmd box I did stack build with my fresh build stack.exe.

This is the result:

d:\testElm\testElm>d:\stack\stack\.stack-work\install\e4874a87\bin\stack build 

Failed to reset to commit 2a026e4c3a93a18006595636e783955223f9b98e, deleting and re-cloning.

"D:\\testElm\\testElm\\.stack-work\\downloaded\\7A15yVYjrQP7\\"

This last line is the directory to delete.

Any idea what is going on?

Kees

[kees Bleijenberg]

And this are the read only files:

[Michael Snoyman]

Where did you get Git from? Maybe it's mistakenly setting the files to readonly?

My guess is next step would be to create a new recursive delete function that can handle these types of file permissions.

I uses git from https://git-scm.com/download/win. After updating, the problem remains.

git clone https://github.com/commercialhaskell/stack.git wprked flawless

Maybe this is a SSH issue?

Kees

[Michael Snoyman]

I don't know where to go on figuring out what causes the files to be read only. But if you can write a recursive delete function that can deal with the read only files, that would be a good solution. We may also want to consider simply warning about the exception and then moving on.

Maybe it has something to do with this: http://superuser.com/questions/457303/how-can-i-make-files-i-check-out-with-git-on-windows-writable-by-default-in-cygw

[Stéphane Laurent]

Issue open here: https://github.com/commercialhaskell/stack/issues/2423

For me this occurs when I have some github packages in stack.yaml.

Two solutions : remove git from the path, or delete the folder .stack-work/downloaded.
