Can't copy and rename on Windows.

[myuhe]

On dired-async and helm-async, copy and rename don't work correctly. when copy an rename on dired using dired-async and helm-async, shows " copy/rename proceeding asynchronously..." on minibuffer.

But, It don't call callback, and files can't copy and rename.

This problem occur on Windows. On Linux, it works correctly.

Hi Myuhe,

I just tested now and it is working fine from helm.

1) be sure your emacs exe is in your PATH env var.

2) Load ONLY helm-async.el and NOT dired-async.el:

(when (require 'dired-aux)
  (require 'helm-async))

Should be enough to load package.

I checked PATH, and loaded ONLY helm-async.el too. But don't fix it.

I also tried starting from a dired buffer and hitting "C" which I usually don't do (I never use dired) and it worked fine too (In this case it use find-file+helm-mode)

From helm-find-files no problem too.

I think you still have a problem with emacs in path env which is not found by start-process, or autorisation problem (Windows7 ?), the point is your child emacs is never started, it is not a lisp problem.

When it is hanging try to see if you have a second emacs process running.

I tested this code. environment is Windows7 and Emacs 24.2.1.

(async-start
       (lambda ()
         (message "This is a test")
         (sleep-for 3)
         222)
       (lambda (result)
         (message "Async process done, result should be 222: %s"
                  result)))

In this code, child process boots fine.

But, copy and rename with helm-async can't boots child process.

Are you sure the definition of dired-create-file is not overwritten by something else ? Try to eval manually the definition of dired-create-file that is in helm-async.el with C-M x, or reload the file and try again (Also be sure to kill all running emacs in background).

[myuhe]

eval manually dired-create-file in helm-async.el, But don't fix...

So I don't know... I will try to setup a Windows7 machine in virtualbox as soon as possible and try to use helm-async.el there to see if I can reproduce.

It worked on Windows7 on some directories and fail in other ones with "file-error"'s, where it is working in WindowsXP in directories with similar names, so it is really something specific to Windows7, but my knowledge on this system is limited. Try to set helm-async-log-file to something that exists on Windows (e.g "~/.emacs.d/helm-async.log") to have errors logged. Thanks.

As helm-async doesn't exists anymore, I close this, feel free to reopen after trying the new dired-async.el
