X-Debbugs-CC: Robert Vollmert <r...@vllmrt.net> Hello,
in the 1.0-beyond-discussions, Robert asked that Stacktraces should be
more clear. I refer to this message (lists.gnu.org is down, so I
cannot link):
From: Ludovic Courtès <l...@gnu.org>

Here is my example. I'm on top of
48eb71aea807262210c38b5fb675d747adfccff3
First the full stacktrace, below are some comments:
./pre-inst-env guix lint -c cve freecad
Backtrace:reecad@0.18.2-1.dbb4cc6 [cve]...

OK, this is semi-readable but I will explain a bit what I find
strange/unreadable:
In guix/scripts/lint.scm:
1152:4 6 (run-checkers #<package freecad@0.18.2-1.dbb4cc6 gnu/p?> ?)
--> OK: This is perfectly readable. I know in which procedure I am,
in which line, the line matches my source code. Fine.
In srfi/srfi-1.scm:
640:9 5 (for-each #<procedure 3e473c0 at guix/scripts/lint.scm?> ?)
--> This is OK, though it could print the line of the procedure?
In guix/scripts/lint.scm:
933:4 4 (check-vulnerabilities _)
928:9 3 (_ _)
--> 933: Nice, I'm in check-vulnerabilities. But why is there no argument?
--> What is this strange second line: (_ _)? Why is there nothing written?
Is that due to tail-recursion?
In unknown file:
2 (force #<promise #<procedure 7f1ce3ab6228 at guix/scrip?>)
--> Why is this in a "unknown file"?
--> Is this force/promise making my stacktrace more unreadable?
In guix/scripts/lint.scm:
917:24 1 (_)
--> Uh. Any more details?. Is "(_)" the call to "(current-vulnerabilities*)"?!
In ice-9/boot-9.scm:
829:9 0 (catch srfi-34 #<procedure 37e64e0 at guix/scripts/lin?> ?)
ice-9/boot-9.scm:829:9: In procedure catch:
In procedure connect: Connection timed out
--> Now, wait: The real problem happens somewhere down here and I don't
have any detailed stacktrace about that?
I have to manually go down into current-vulnerabilities*,
call/nw/failsaife, etc? Why don't I get the details from here?
Is this because in "call-with-networking-fail-safe", line 900 we
through newly:
(args
(apply throw args))))))
but then the stacktrace gets lost?
Would there be a throw-with-caused-by?
