Delphi Exception handling code review reminders

Posted by jpluimers on 2020/06/18

I bumped into [WayBack]When an exception is nil in the exception handler – twm’s blog for some legacy code a while ago.

Some code review reminders:

  • raise Exception( is always wrong: no exception instance is created
  • Exception.Create( without a raise is wrong most of the times
  • except end is almost always wrong
  • except and finally in encompassing blocks often is a code smell

I need to check which ones are caught by [WayBack] Code Analysis Tool | FixInsight for Delphi (which is not at [WayBack] TMS Software | VCL, FMX, ASP.NET, .NET controls & components for Delphi, C++Builder & Visual Studio | TMS FixInsight Pro.)
