bsddb environment lock failure

by: Barry | last post by:

I have python2.4.1 installed on two machines: -- one is Fedora core 1, where the bsddb module works fine -- one is Redhat ES 3.0, and I installed mysql 4.1 (and mysql-python2.1) after putting the newer python on the machine. python2.2, which came with Redhat ES, works fine, so I suppose I messed up the build. I much appreciate any insight in how to fix this.

bsddb - help needed with btflags values for Python

by: sconnoll | last post by:

import bsddb bsddb.btopen(file, flag='c', mode=438, btflags=0, cachesize=None, maxkeypage=None, minkeypage=None, pgsize=None, lorder=None) Can anyone help me with the values to use for btflags? I'd like to tell the database manager that I want to allow duplicate values. The ORACLE Berkeley documentation addresses C (not Python), so I can't find the approprate btflags values documented for Python anywhere.

The easy way to turn off automatic updates for Windows 10/11

by: Hystou | last post by:

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

AI Job Threat for Devs
