New issue 6295 by [hidden email]: '/tmp/github.zip' claimed to exist  
by FileSystem, but FileDirectory tells the truth that it does not exist  
(pharo2.0)
http://code.google.com/p/pharo/issues/detail?id=6295

Honestly don't know how to reproduce this because FileSystem is not telling  
the truth...

I have code that looks like this:

downloadFile: url to: outputFileName
     " self  
downloadFile: 'https://github.com/dalehenrich/sample/zipball/1.0'"

     | in out err proc |
     in := (' -L ' , url) readStream.
     out := FileStream forceNewFileNamed: outputFileName.
     err := FileStream forceNewFileNamed: '/tmp/curl.err'.
     proc := OSProcess thisOSProcess
         forkJob: '/usr/bin/curl'
         arguments:
             {'-L'.
             url}
         environment: nil
         descriptors: (Array with: nil with: out with: err).
     proc ifNil: [ OSProcess noAccessorAvailable ].
     [ proc isRunning ] whileTrue: [ (Delay forMilliseconds: 100) wait ].
     out close.
     err close

and I'm getting a CannotDeleteFileException because FileSystem thinks the  
file '/tmp/github.zip' (outputFileName) exists. Asking FileDirectory if the  
file exists answers false. Presumably the file did exist and was possibly  
even deleted by the forceNewFileNamed: code, but by the time I started  
looking the file was long gone...

I'm running my tests in the Pharo-2.0 oneclick (Pharo2.0a-#20182) on the  
mac so I'm (presumably) using a captive vm...

I am attempting to port my working version of metacello to Pharo-2.0, but  
this is a show-stopper for me.

Comment #1 on issue 6295 by [hidden email]: '/tmp/github.zip'  
claimed to exist by FileSystem, but FileDirectory tells the truth that it  
does not exist (pharo2.0)
http://code.google.com/p/pharo/issues/detail?id=6295

on closer examination it appears that the following sequence is failing  
when the file '/tmp/github/zip' starts out existing:

| dir fullName localName |
fullName := '/tmp/github.zip'.
dir := fullName asFile.
localName := dir basename.
dir delete.
dir exists.

`dir delete` actually deletes the file, but `dir exists` answers `true` ...  
once it answers `true` it seems to think the file exists until I restart  
the image ... so this is likely to be a vm primitive bug...

I don't know... there is a really weird bug around with FileSystem.., me  
and Camillo are trying to catch it but is elusive... anyway, I'm on it...

this is not happening anymore with latest vm's, so I'm closing the issue
