No debug symbols for git

[Alex Bennée]

I'm trying to do some system profiling on a server that's behaving poorly while cloning repositories. To do proper profiling I need the debug symbols but I can find them even with the ddebs.ubuntu.com repo added.

root@vsbldhost:/scratch/root# apt-cache search dbg | grep "git"
gtkam-dbg - GTK+ application for digital still cameras (debugging symbols)
jigit-dbgsym - debug symbols for package jigit
gitg-dbgsym - debug symbols for package gitg
digitemp-dbgsym - debug symbols for package digitemp
logitech-applet-dbgsym - debug symbols for package logitech-applet
flegita-gimp-dbgsym - debug symbols for package flegita-gimp
callgit-dbgsym - debug symbols for package callgit
engauge-digitizer-dbgsym - debug symbols for package engauge-digitizer
qgit-dbgsym - debug symbols for package qgit
sigit-dbgsym - debug symbols for package sigit
flegita-dbgsym - debug symbols for package flegita
digitools-dbgsym - debug symbols for package digitools

Yeah, git is a weird package that doesn’t use Debhelper and thus isn’t subject to pkg-create-dbgsym’s wrapper for dh_strip. This can probably only be fixed by rewriting the package with Debhelper.

[Alex Bennée (ajbennee)]

Does that make this an upstream bug for Debian?

I've also found another package without debug symbols (libgdk-pixbuf2.0-0), should I raise a bug for that as well?

[Anders Kaseorg (andersk)]

Well, Debian doesn’t generate automatic debug symbol packages like Ubuntu does, at least not yet, so Debian isn’t directly affected. It might still be worth filing a Debian bug anyway; the maintainers might still be open to the idea of using Debhelper, though it probably won’t happen immediately.

(libgdk-pixbuf2.0-0 does have debug symbols: http://ddebs.ubuntu.com/pool/main/g/gdk-pixbuf/ )

[Anders Kaseorg (andersk)]

Fixed in git 2.10.1-1, which I migrated to Debhelper.
