When I see my system.log I see a error name :

2015-12-16T15:15:19+00:00 DEBUG (7): is_readable() expects parameter 1
to be a valid path, string
given/data/web/public/lib/Varien/Io/File.php

Does anyone know where this error comes from and what I can do about it?

When I go to the file file.php. I see the code:

protected function _checkSrcIsFile($src)

 $result = false;
 if (is_string($src) && is_readable($src) && is_file($src)) 
 $result = true;
 
 return $result;
 

The log entry

is_readable() expects parameter 1 to be a valid path, string given

occurs due to a bug in the Varien library. The method Varien_Io_File::write() can be used to either

1. write given data to a given destination file or


2. copy the contents from a given source file to a given destination file.

These use cases are distinguished by checking the second parameter $src of the aforementioned method via call to Varien_Io_File::_checkSrcIsFile().

If $src turns out to be a filename, its contents are copied to the destination (use case 2). Otherwise it is interpreted as plain data (use case 1). The check applies function.is-readable which always emits given warning in use case 1.

What you can do about it:

• Replace the initial call to Varien_Io_File::write()
  


• Fix the erroneous conditional switch


• Ignore the log entries

The above answer is not clear at all because $src is being passed as an argument in the function so I don't understand where you gonna replace $src with Varien_Io_File::write() so this doesn't seem like a solution to this warning.
who got a solution for this problem?
