POPython logging - exc_info only for file handler
text
Body
copied!<p>I define root logger and handlers for it:</p> <pre><code>_root = logging.getLogger() _sh = logging.StreamHandler() _fh = logging.FileHandler('./error.log', delay = True) _root.addHandler(_sh) _root.addHandler(_fh) </code></pre> <p>And module logger instance:</p> <pre><code>_log = logging.getLogger("Main") # In other file _log = logging.getLogger("Configuration") </code></pre> <p>Now i call <code>_log.exception</code> in try..except block:</p> <pre><code>_log.exception("Test") </code></pre> <p>Now i get traceback in console and file. I try to suppress printing of exc_info with console handler, but not with file handler:</p> <pre><code>class _TraceBackFilter(logging.Filter): def filter(self, rec): rec.exc_info = None return True _sh = logging.StreamHandler() _sh.addFilter(_TraceBackFilter()) _root.addHandler(_sh) </code></pre> <p>This works on both file and console handler, traceback is completely removed for all handlers, but i need this only for console. Is any way to suppress exc_info only for console handler, not for file handler?</p> <p><strong>EDIT:</strong></p> <p>I modify <code>_TraceBackFilter</code> class.</p> <pre><code>class _TraceBackFilter(logging.Filter): def filter(self, rec): if rec.exc_info: logging.getLogger(rec.name).log(rec.levelno, rec.getMessage()) return False else: return True </code></pre> <p>Now its works for console handler, but in file I have doubled messages, one with and one without traceback.</p>
