Python 2.3 startup is slow (was Re: [Mailman-Developers] python is slow)

In fact, last June Guido declared that a must-fix bug, but it dropped below the radar and we had to punt when Apple needed 2.3 quickly. Anyone who wants to take a stab at working on it would be most welcome. -- Aahz (aahz(a)pythoncraft.com) <*> http://www.pythoncraft.com/ Weinberg's Second Law: If builders built buildings the way programmers wrote programs, then the first woodpecker that came along would destroy civilization.

That last line should read: session.Logon (ProfileInfo="%s\n%s" % (EXCHANGE_SERVER, MAILBOX_NAME)) Sorry; that's the only one I didn't cut-and-paste into a Python session before posting.

C++ and Python: how can I make it stop?
by Heikki Salo Dec. 30, 2003

Dec. 30, 2003

I have decided to embedd Python into my C++ application and I have one question about it. Everything works perfectly, but I havenŽt figured any way to stop the interpreter when it is executing (using PyRun_SimpleFile) a python script. I expose a callback-function (so scripts can call it) in my programs API which should stop the processing, but as I said, I have no idea how to do that. I tried to use sys.exit, but it kills the whole application.

>From: Lindstrom Greg - glinds [mailto:Greg.Lindstrom@acxiom.com] > >I have written a script to monitor my MS Exchange mailbox for certain >messages and post information to an MS SQL Server Database. Everything >works great except that each time I run the script I am >prompted by Windows >to choose the profile of the mailbox via a dialog box. > >Is there any way to either specify the profile or accept the default? You have three options that I can think of. I assume you're using CDO (ie the MAPI.Session COM object). Each of the techniques should leave you with a working session. The Logon method has a number of other parameters controlling, for example, whether a dialog box should be displayed if the logon fails and so on. Consult MSDN for details: it's quite lucid on the subject. 1) Hardcode a profile name with the options you need and pass it in: <code> import win32com.client session = win32com.client.Dispatch ("MAPI.Session") session.Logon (ProfileName="Tim Golden") # obviously replace my name by the # display name of your profile, the # one that appears in the dialog box </code> 2) If you don't have that much control, find the user's default profile and use that: <code> import win32com.client import _winreg reg1 = "\\".join ([ "Software", "Microsoft", "Windows NT", "CurrentVersion", "Windows Messaging Subsystem", "Profiles" ]) reg2 = "\\".join ([ "Software", "Microsoft", "Windows Messaging Subsystem", "Profiles" ]) try: key = _winreg.OpenKey (_winreg.HKEY_CURRENT_USER, reg1) except: try: key = OpenKey (_winreg.HKEY_CURRENT_USER, reg2) except: key = None if key: try: default_profile, should_be_string = \ _winreg.QueryValueEx (key, "DefaultProfile") except: default_profile = "" session = win32com.client.Dispatch ("MAPI.Session") session.Logon (ProfileName=default_profile) </code> 3) One other option, with limitations, is to construct a profile info string on the fly, and pass that to the logon method: <code> import win32com.client EXCHANGE_SERVER = "xyz" MAILBOX_NAME = "tim.golden" # # Obviously replace the server and # mailbox names to suit. # session = win32com.client.Dispatch ("MAPI.Session") session.Logon ("%s\n%s" % (EXCHANGE_SERVER, MAILBOX_NAME)) </code> TJG ________________________________________________________________________ This e-mail has been scanned for all viruses by Star Internet.
