you can just submit this change as submitreq if you want (there is no clear maintainer of find-debuginfo.sh)

i'll assign to mls though just in general ;)

[Mmeeks (mmeeks)]

Oh - I'd really prefer someone who knows what they are doing to review my patch - manifestly I have no idea here; if they could submit it too - that'd be really helpful.

I assume the prospect of more space on the various Live-CDs is generally interesting to people too.

- finddebuginfo.diff: disable debuginfo for mono at the moment

No idea why.

[Rguenther (rguenther)]

I don't see where finddebuginfo.diff changes anything for mono.

But ...

+# Find mono debugging data
+if [ -x "/usr/bin/mono" ] ; then
+ echo "find in $RPM_BUILD_ROOT/usr/lib"
+ find $RPM_BUILD_ROOT/usr/lib -type f \( -name "*.dll.mdb" -or -name "*.exe.mdb" \) | sed "s|$RPM_BUILD_ROOT||" >> "$LISTFILE"
+fi
+

so you are special-casing packages that have /usr/bin/mono. Why not simply
manually add a

Package: debuginfo
...

%files debuginfo
...

which is possible now (well, not mono-debuginfo as that exists already and
you can't add to it - I didn't see that would be necessary yet). Likely
what you want is something like mono-runtime-debuginfo anyway (or wherever
that pieces are).

The proposed solution to finddebuginfo.sh is a hack. If more packages
would provide debuginformation in a mono format then if a mono
build environment is present there needs to be a way to identify a
*.dll.mdb or *.exe.mdb file as proper debuginformation and the packaging
should be done for all packages not just the one containing /usr/bin/mono.

Hi Richard !

oh - well, this is not very simple when you have to add it to a lot of packages (60 or so) - and in general, some pleasant way to drop (known to be) debuginfo information automatically into -debuginfo files is surely more pleasant ? This presumably is the thinking underlying a central find-debuginfo.sh script.

The check for /usr/bin/mono - is not intended to make this specific to a single package - but to make it specific to those packages that have a BuildRequires of mono - ie. to reduce any chance of false positives with people calling their files "foo.dll.mdb" but them not being either a DLL or a debuginfo file ;-) I tend to think that is pretty unlikely, and in these cases they would want those files in a -debuginfo file anyway - so we could easily remove that.

[Rguenther (rguenther)]

Ah, indeed - I misread that part of the patch. Is there a way to have
mono say "yes, this is proper debuginfo for me!"? Like

mono --verify-this-is-debuginfo /path/to/the/file

?

Does the mono debugger find the debuginformation if it is copied to
the /usr/lib/debug/ shadow tree? I see the debuginfo files do not
end in .debug, so at the moment they wouldn't be picked up by rpm,
but that would be easy to fix.

[Mmeeks (mmeeks)]

Martin - any idea about this ? it would be nice to have some debug sniffing tool that we could use to reliably detect real debuginfo files; and Richard wonders - could we look in the shadow path for these files ? [ moving them across to there would be a little cleaner, and more consistent obviously ].
