晋太元中，武陵人捕鱼为业。缘溪行，忘路之远近。忽逢桃花林，夹岸数百步，中无杂树，芳草鲜美，落英缤纷。渔人甚异之，复前行，欲穷其林。 　　林尽水源，便得一山，山有小口，仿佛若有光。便舍船，从口入。初极狭，才通人。复行数十步，豁然开朗。土地平旷，屋舍俨然，有良田、美池、桑竹之属。阡陌交通，鸡犬相闻。其中往来种作，男女衣着，悉如外人。黄发垂髫，并怡然自乐。 　　见渔人，乃大惊，问所从来。具答之。便要还家，设酒杀鸡作食。村中闻有此人，咸来问讯。自云先世避秦时乱，率妻子邑人来此绝境，不复出焉，遂与外人间隔。问今是何世，乃不知有汉，无论魏晋。此人一一为具言所闻，皆叹惋。余人各复延至其家，皆出酒食。停数日，辞去。此中人语云：“不足为外人道也。”(间隔 一作：隔绝) 　　既出，得其船，便扶向路，处处志之。及郡下，诣太守，说如此。太守即遣人随其往，寻向所志，遂迷，不复得路。 　　南阳刘子骥，高尚士也，闻之，欣然规往。未果，寻病终。后遂无问津者。 .

:mod:`cgitb` --- Traceback manager for CGI scripts
==================================================

.. module:: cgitb
   :synopsis: Configurable traceback handler for CGI scripts.

.. moduleauthor:: Ka-Ping Yee <ping@lfw.org>
.. sectionauthor:: Fred L. Drake, Jr. <fdrake@acm.org>

**Source code:** :source:`Lib/cgitb.py`

.. index::
   single: CGI; exceptions
   single: CGI; tracebacks
   single: exceptions; in CGI scripts
   single: tracebacks; in CGI scripts

--------------

The :mod:`cgitb` module provides a special exception handler for Python scripts.
(Its name is a bit misleading.  It was originally designed to display extensive
traceback information in HTML for CGI scripts.  It was later generalized to also
display this information in plain text.)  After this module is activated, if an
uncaught exception occurs, a detailed, formatted report will be displayed.  The
report includes a traceback showing excerpts of the source code for each level,
as well as the values of the arguments and local variables to currently running
functions, to help you debug the problem.  Optionally, you can save this
information to a file instead of sending it to the browser.

To enable this feature, simply add this to the top of your CGI script::

   import cgitb
   cgitb.enable()

The options to the :func:`enable` function control whether the report is
displayed in the browser and whether the report is logged to a file for later
analysis.


.. function:: enable(display=1, logdir=None, context=5, format="html")

   .. index:: single: excepthook() (in module sys)

   This function causes the :mod:`cgitb` module to take over the interpreter's
   default handling for exceptions by setting the value of :attr:`sys.excepthook`.

   The optional argument *display* defaults to ``1`` and can be set to ``0`` to
   suppress sending the traceback to the browser. If the argument *logdir* is
   present, the traceback reports are written to files.  The value of *logdir*
   should be a directory where these files will be placed. The optional argument
   *context* is the number of lines of context to display around the current line
   of source code in the traceback; this defaults to ``5``. If the optional
   argument *format* is ``"html"``, the output is formatted as HTML.  Any other
   value forces plain text output.  The default value is ``"html"``.


.. function:: handler(info=None)

   This function handles an exception using the default settings (that is, show a
   report in the browser, but don't log to a file). This can be used when you've
   caught an exception and want to report it using :mod:`cgitb`.  The optional
   *info* argument should be a 3-tuple containing an exception type, exception
   value, and traceback object, exactly like the tuple returned by
   :func:`sys.exc_info`.  If the *info* argument is not supplied, the current
   exception is obtained from :func:`sys.exc_info`.
