Answer 1

EurekaLog is extremely effective for all applications. Just configure it so that it will log the exceptions to a file and doesn't display exception dialogs at all.

+1 but "effective" is not fully correct, more like "extremely effective" (: – Linchpin

Answer 2

Our Open-Source logging classes have an exception interceptor with full call stack, including source code lines.

The debugging information is highly compressed (better than zip or any other formats), optionally into the exe.

Open Source, works with Delphi 5 up to XE2.

In its latest version (use the one from the source code repository - i.e. currently 1.16), it is also able to log exceptions within libraries (i.e. within .dll or .bpl), as your request explicitly state.

There are other features, like customer-side profiling, which may help your customer support, and application enhancements, from real data (not only in test benchs).

Wow Arnaud! Your stuff just keeps getting better and better! – Trilbie

If you recommend it as solution, it would be nice to have at least minimal example of code, how to add/activate such exception interceptor etc. For specialized libraries it is enough usually to add unit to the project, but not in this case i guess. Compression of MAP-file fails on 36Mb file (some fixed-size internal buffer is too small, it should be calculated from filesize probably). – Haro

@AndreiGalatyn The issue with huge .map file has been fixed yesterday. And you can find samples at github.com/synopse/mORMot/tree/master/SQLite3/Samples/… – Understand

@Arnaud Seems nighty build 2015-02-21_170025 still doesn't include the fix, i will check it tomorrow. But at first view it looks very interesting (just 3 units with full sourcecode and they do all what i need and more). Will try to test on real projects. Thank you! – Haro

You can also use MadExcept to get the stack for your application. Here you have a similar question madExcept, getting top of current stack

Answer 4

I've been using MemCheck before to render call stacks, but I'm not sure it still works with the most recent Delphi versions.
