Copying and pasting a component between projects no longer causes a crash when the ‘Cut/Copy/Paste keys’ application option is set to ‘x,c,v’ (#6520). The last three data points of a monitored signal are now properly plotted and viewable on graphs (without the need to zoom in) (...
dozen lines of code. If a test suddenly fails, you know that it was introduced in the little bit of code you just changed. Not only is it easier to detect when you've introduced an error, but it is also easier to find the code that causes the error, reducing the time spent ...
An error can be shown on the Visualforce page if a user enters data on a Visualforce page that accesses a standard controller and that data causes a validation rule fault. The <apex: pagemessage> or <apex:message> method beneath the <apex:page> will be used to display the error if the...
A buffer overflow can occur inadvertently or when a malicious actor causes it. Athreat actorcan send carefully crafted input -- referred to asarbitrary code-- to a program. The program attempts to store the input in a buffer that isn't large enough for the input. If the excess data is ...
options are different, depending on configurations and platforms. The common values, such as _WIN32, are displayed directly. The values that are not common appears as “<different options>”. In order to see the actual values, select a single configuration and a single platform in dropdowns....
Here, one of the variables causes a zero division error. Python 3.10 tells you about the problem, but it doesn’t indicate the culprit. In Python 3.11, the traceback will include visual feedback about the exact location on a line that raised an exception. You’ll also have a programmatic...
