mod_python works as standalone, does not as service (Windows XP)
My mod_python 3.1.4 installation works when Apache 2.0.54 is run in standalone mode (apache -k standalone) but refuses to operate when run as a service (apache -k restart). Logs yield the usual and well-known "make_obcallback: could not import mod_python.apache" error. I have tried PYTHONHOME, LoadFile python24.dll (2.4.2) with no result. I have read *all* threads about make_obcallback that google found. What's even weirder I had this module working yesterday but had to make apache cleanup (fresh installation) and now this is completely stuck. I remember that last time I just had to reinstall Apache over existing mod_python files to get it working but this time it just pointless. I thank everyone who understand differences between standalone and service modes of Apache better than I do. -- http://mail.python.org/mailman/listinfo/python-list
65K length limitation in MySQLdb?
I'm trying to using the following code insert a long string into a
MySQL table, the data type is of that column is TEXT. When the length
of the content is longer than 65K, it get truncated in the database.
Any idea about this? Thanks
import MySQLdb
import MySQLdb.cursors
class MyDb:
def __init__(self):
self.conn = None
self.cursor = None
def connect(self):
self.conn = MySQLdb.Connect(
host='localhost', user='user',
passwd='password', db='testdb',compress=1,
cursorclass=MySQLdb.cursors.DictCursor)
self.cursor = self.conn.cursor()
def insert(self, id, content):
try:
self.cursor.execute("INSERT INTO `my_table`(`id`,
`content`) VALUES (%s, %s);", (id, content));
except:
print "Failed to insert new record"
pass

it's possible that the cron doesn't have the environment variables you
have, especially $PATH. So the script failed to find the command it
need to create the image.

Package for fast plotting of many data points in Python?
Hi, I am programming a oscilloscope module in Python. For this reason, I want to plot very many data points as fast as possible. This can be more than 100 000 at once. So far I have been using the ploting module of wxPython. However, it becomes unstable for more than 25000 points. Can someone recommend me a faster plotting library? It would be really cool if one could embed this in wxPython. If someone has an idea I would be very glad about answer. With kind regards, Daniel -- http://mail.python.org/mailman/listinfo/python-list
