Sebb updated IO-384:
--------------------
Summary: New FileUtils method to copy file which might change in size
(was: New FileUtils method to copy file which might increase in size)
> New FileUtils method to copy file which might change in size
> ------------------------------------------------------------
>
> Key: IO-384
> URL: https://issues.apache.org/jira/browse/IO-384
> Project: Commons IO
> Issue Type: New Feature
> Reporter: Sebb
>
> As mentioned in IO-383, FileUtils.doCopyFile caches the file size.
> This means that a growing file (e.g. a log file) may cause the method to
> report failure.
> It might be useful to have a method which keeps looping until there is no
> more input; this should not throw an IOE if the sizes are different.
> More data may have been added - or the file truncated - between completing
> the copy and checking the size.
> The method should return the total bytes written; the caller can then check
> if the count is OK.
