copied!<p>The problem is <code>trace</code> method and <code>print</code> statements in the <code>win32comext\axscript\client\framework.py</code> because in the COM components writing to the <code>sys.stdout</code> or <code>sys.stderr</code> like the <code>print</code> statement causes an exception for example <code>trace("Debugging extensions (axdebug) module does not exist - debugging is disabled..")</code> at the line 572 of <code>framework.py</code> causes an exception.</p> <p>One workaround is adding <code>import win32traceutil</code> in the <code>framework.py</code>. The <code>win32traceutil</code> redirects output to <code>win32trace remote collector</code> and solve the problem without need to enabling debugging witch cause performance issues.</p> <p>Another workaround is redirecting <code>stdout</code> and <code>stderr</code> to null, you can add following code snippet at the top of <code>framework.py</code>.</p> <pre><code> f = open('nul', 'w') sys.stdout = f sys.stderr = f </code></pre> <p><strong>UPDATE: The root cause and the solution</strong></p> <p>There is already a mechanism in <code>framework.py</code> to prevent print and trace statements to raise an exception but the problem is in the <code>write</code> method of <code>SafeOutput</code> class. When tracing and debugging is not enabled, in the write method an exception occurs and <code>win32api.OutputDebugString</code> in the except clause will invoke with the wrong encoding which cause an exception. Because the <code>win32api.OutputDebugString</code> accept Unicode string not a multibyte character set (MBCS) as an argument.</p> <p>The solution:</p> <p>in the <code>win32comext\axscript\client\framework.py</code> in the <code>SafeOutput</code> class</p> <pre><code>class SafeOutput: softspace=1 def __init__(self, redir=None): if redir is None: redir = sys.stdout self.redir=redir def write(self,message): try: self.redir.write(message) except: win32api.OutputDebugString(message.encode('mbcs')) def flush(self): pass def close(self): pass </code></pre> <p>just change </p> <pre><code>win32api.OutputDebugString(message.encode('mbcs')) # ANSI Enconding </code></pre> <p>to </p> <pre><code>win32api.OutputDebugString(message) # Unicode </code></pre>
