Delphi call stack from exception…

Posted by jpluimers on 2017/08/02

Lars Fosdal:

MADExcept and Eurekalog are good products (and there is a JVCL tool as well). If you run your app in the IDE, you get the stack there – but for now, you need to acquire a third party package to get it runtime.I don’t disagree with the wish for a basic call stack tool, that works cross platform, but it would affect third party developers.

Stefan Glienke:

Whats the problem? You attach handlers to Exception.GetExceptionStackInfoProc, GetStackInfoStringProc and ` and just call a function that grabs the map or td32 info and generates the callstack – if you don’t want to spend any money for a high quality tool like madExcept (can even use it for free for non commercial use!) then use JclDebug.pas

I edited in some URLs above; the actual info is from: Why Delphi (like other developer environments) natively not included full call stack for every exception… [WayBack] (which is because it would kill even more of the Delphi 3rd party market).

And it taught me about this by madshi (of MADExcept fame):

DebugEngine is a collection of utils related to debug stuff (stack trace, CPU registers snaphot, debug info,…). Basically, I started to write a commercial error log plugin for Delphi, then I noticed that my internal framework got bigger and bigger. So I decided to share it with the community in hope it will be useful.

And there is the JCL ExceptDlg.pas which is quite easy to use: just add it anywhere to your project and the global exception handler will show you a stack trace provided you have a .MAP file or .TDS file (which contains TD32 symbol information) in the same directory as your .EXE.

Delphi – unmangle names in BPL’s – Stack Overflow

Posted by jpluimers on 2016/10/12

Check out $(BDS)\source\cpprtl\Source\misc\unmangle.c – it contains the source code for the unmangling mechanism used by TDUMP, the debugger and the linker. (C++Builder and Delphi use the same mangling scheme.)

This has been around as long as BCC itself. However the file was called um.c instead of unmangle.c in older versions

Source: [WayBackDelphi – unmangle names in BPL’s – Stack Overflow both by User Moritz Beutel.

It’s the same mangling used in the TD32/TDS and MAP symbols.

And neede to improve https://github.com/jpluimers/map2dbg (which is my fork of https://github.com/andremussche/map2dbg) which contrary to it’s name also supports TDS/TD32 conversions in tds2pdb. The code is C# and works in virtually any Visual Studio version of 2012 and younger.

SmartBear AQTime links

Posted by jpluimers on 2016/06/02

Since they’re hard to find on-line, and sometimes I need them when not having access to my collective browser or email history:

Notes:

  1. The AQTimeDemo.exe is the same as the latest AQTime###.exe (functionality depends in license).
  2. The installation from Windows Explorer sometimes fails with the below message. Installation from the command-prompt works, but you need to run it from an Administrator command-prompt:

---------------------------
E:\TEMP\AQtime824.exe
---------------------------
Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item.
---------------------------
OK
---------------------------

To get going for my special case, I watched some sample videos (which I did get to work in Internet Explorer but not in Chrome forty-something):

I needed it to do some profiling comparisons of services running under different configurations.
