Why does HRESULT begin with H when it’s not a handle to anything? – The Old New Thing
Posted by jpluimers on 2020/02/06
Interesting bit of history: [WayBack] Why does HRESULT begin with H when it’s not a handle to anything? – The Old New Thing.
TL;DR:
- It used to be a handle
- Few programs cared about the underlying objects
- Managing the underlying objects was way too expensive
- It got trimmed down to a number, but the name stuck

If you have enough guts to keep Castalia enabled and have Delphi Berlin or higher, then you can use this shortcut:

The magic Delphi ReturnAddress intrinsic
Posted by jpluimers on 2020/02/05
I could not find any official place where ReturnAddress is documented even though it is used at quite a few places in the RTL, VCL, FMX and 3rd party libraries like DUnitX, Spring4D, JCL, ReportBuilder, TeeChart.
I tried searching it in the contexts of Delphi 2007, Delphi 2009, but there is only a [Archive.is] different System.ObjAuto.TParameters.ReturnAddress documented in XE2 and higher.
procedure Abort; begin raise EAbort.CreateRes(@SOperationAborted) at ReturnAddress; end;
There is a (usually broken*) ReturnAddr function used in various places of the RTL/VCL/FMX and (therefore wrongfully copied) in many other peoples code.
function ReturnAddr: Pointer; // From classes.pas asm MOV EAX,[EBP+4] // sysutils.pas says [EBP-4], but this works ! end;
- See the above link; I think this was fixed in Delphi XE, but the issue is still open.
Related to the above is the documented ExceptAddr.
I’ve used this in my ExceptionHelperUnit to build a GetStackTrace function in the example gist below.
I found these posts documenting the behaviour of the above intrinsic functions and more:

- [WayBack] delphi – Undocumented intrinsic routines – Stack Overflow
- [WayBack] exception – What does `at ReturnAddress` mean in Delphi? – Stack Overflow

[WayBack] I love installers that can download and install in parallel threads. Embarcadero and Zypper can learn from this. – Jeroen Wiert Pluimers – Google+
Most Linux distributions have package managers that can do this (apt and yum can), but OpenSuSE zypper (actually ZYpp) cannot even download packages in parallel:
- [WayBack] [feature request] Download multiple packages at the same time · Issue #104 · openSUSE/zypper · GitHub
- [WayBack] parallel downloads while doing zypper distribution upgrade · GitHub
- [WayBack] [openFATE 307862] zypper parallel downloading of packages
- [WayBack] openFATE – #307862: zypper parallel downloading of packages
- [WayBack] openFATE – #318807: Practical steps to parallel downloading of updates
- [WayBack] openFATE – #120340: Decouple download and installation
- [WayBack] openFATE – #312840: Evaluate libzypp thread safety
- [WayBack] TUMBLEWEED Is there anyway to speed up ZYpp’s downloading of packages?

Embarcadero is in the same state as zypper.
