Interesting insights by Andreas Hausladen Twitter on the Delphi splash screen process, license file handling

Posted by jpluimers on 2020/05/05

Interesting insights from [WayBackAndreas Twitter: “I was joking about #Delphi’s splash screen to be shown later so Embt can claim that it finishes much faster now. Today my Internet was down and guess what I had to “witness”. Seattle: 22 sec splash screen time Tokyo: 2 sec splash screen time Sounds fantastic, but…… https://t.co/FGtnJQZDyc”:

  • in earlier versions part of the copy protection (WinVerifyTrust calls) were done after the splash screen was visible and now they are done before.
  • That the WinVerifyTrust call took so long was because Windows (not Delphi) wanted to check for revoked certificates in the first WinVerifyTrust call (due to the missing only-cache flag) and my router seems to not like it if the modem doesn’t have a connection/link to the provider
  • consider using FILE_FLAG_DELETE_ON_CLOSE so that if the IDE is killed during its start (debug session when you see that you forgot something and want to abort) doesn’t wait ~3 minutes or more until the lock is lifted

More relevant links based on the above:

Via [WayBack] Anyone else saw the video on this Andreas Hausladen post? – Cesar Romero – Google+ where I found this observation interesting:

My vm installs have zero net on by default, host only lan, lan only, and internet provided on demand. I’m noticing a lot of differences in the splash screens of 10.2.2.2.2, often lacking registration confirm info (making me nervous).
