[05:55] <mgedmin> apport is hilariously broken in 15.04
[05:56] <mgedmin> the stack trace ends up in the Disassembly: field because I think it gets confused by gdb's output
[05:58] <Noskcaj> darkxst, Can you please renew my membership to ubuntu-gnome-leaders-board?
[06:01] <darkxst> Noskcaj, done
[06:02] <Noskcaj> ty
[06:02] <darkxst> mgedmin, that would be a pitti Q
[06:02] <mgedmin> yeah, maybe I should file a bug report
[06:02] <mgedmin> unfortunately "apport is hilariously broken, here, look at this: " is not a good bug report
[06:03] <mgedmin> Stacktrace: No symbol "__nih_abort_msg" in current context.
[06:03] <mgedmin> SegvAnalysis: Failure: invalid literal for int() with base 16: '='
[06:03] <mgedmin> I can't even
[06:03] <mgedmin> it's too early in the morning for me
[06:03] <mgedmin>  Python Exception <class 'TypeError'> iter() returned non-iterator of type '_iterator':
[06:03] <mgedmin> inside the Disassembly field that actually contains the stacktrace for some reason
[06:04] <mgedmin> apologies for ranting here
[06:04] <darkxst> yeh that is wierd
[06:04] <mgedmin> I bet apport is parsing gdb's output and getting confused by something
[06:04] <mgedmin> maybe those Python errors
[06:05] <mgedmin> (gdb extensions written in Python 2 with gdb linked against Python 3, I guess?  because nobody cares?)
[06:05] <darkxst> mgedmin, Ubuntu was the first distro to link gdb against python 3
[06:05] <darkxst> most of the upstreams were still on 2, but think fedora may have switched now
[06:06] <mgedmin> porting python 2 code to python 3 is something I could probably help with
[06:06] <mgedmin> but where does that code live?
[06:06] <mgedmin> what package?
[06:06] <mgedmin> I filed https://bugs.launchpad.net/ubuntu/+source/gdb/+bug/1449389, got no response (as usual)
[06:06] <ubot5> Ubuntu bug 1449389 in gdb (Ubuntu) "Python Exception <class 'TypeError'> iter() returned non-iterator of type '_iterator'" [Undecided,New]
[06:07] <darkxst> usually in dbg or dev for the relevant library
[06:07] <mgedmin> ok, ok, I could do my own homework, I suppose
[06:07] <mgedmin> can I get gdb to print a list of .py files it has loaded in this debug session?
[06:07] <darkxst> was that retrace on ubuntu-gnome or launchpad retracer
[06:07]  * mgedmin discovers, again, that apport-retrace is useless
[06:08] <mgedmin> if by "that retrace" you mean the bits I quoted here
[06:08] <darkxst> "apport-retrace -g <crash_file>" not entirely useless
[06:08] <mgedmin> it's from /var/crash/_usr_bin_gnome-shell.1000.crash on my laptop
[06:08] <mgedmin> warning: .dynamic section for "/tmp/apport_sandbox_FQNZiQ/usr/lib/libmutter.so.0" is not at the expected address (wrong library or version mismatch?)
[06:08] <mgedmin> warning: Could not load shared library symbols for /usr/lib/x86_64-linux-gnu/libtxc_dxtn.so.
[06:08] <darkxst> pacakge form staging or archive?
[06:08] <mgedmin> and then the stack trace is nonsensical
[06:08] <mgedmin> gnome3-staging, which complicates things I'm sure
[06:09] <darkxst> yeh, its a different retracer
[06:09] <mgedmin> have I enabled ppa ddebs this time (they got disabled by the upgrade as usual IIRC)?
[06:09] <mgedmin> probably not...
[06:10] <mgedmin> symbol servers, where are they?  (https://randomascii.wordpress.com/2013/03/05/symbols-on-linux-update-fedora-fixes/)
[06:11] <darkxst> mgedmin, if you enable debugging for the pretty-printers it will show more useful info
[06:11] <mgedmin> how do I do that?
[06:13] <mgedmin> info pretty-printer
[06:13] <mgedmin> no, that's useless
[06:14] <darkxst> I forget haven't worked with them in a while
[06:15] <mgedmin> info auto-load python-scripts
[06:18] <mgedmin> the gdb pretty-printers come from libglib2.0-0-dbg
[06:19] <mgedmin> it's a vivid/main package, no ppas involved
[06:19] <mgedmin> source package is glib2.0
[06:20] <darkxst> mgedmin, launchpad retracer does not load them currently
[06:20] <darkxst> our retracer does
[06:20]  * mgedmin tries UDD again: bzr branch ubuntu:vivid/glib2.0
[06:20] <mgedmin> what do you mean by "our retracer"?
[06:20] <darkxst> atleast i don't think pitti merged my changes for that yet
[06:21] <darkxst> crashes on gnome3-staging packages are retraced by a retracer that I run
[06:21] <darkxst> normally PPA's dont get retraced
[06:22] <mgedmin> ah, for bugs filed against ubuntu-gnome?
[06:23] <darkxst> yes, for any package originating from gnome3-team ppa's
[06:23] <darkxst> gtg, be back in half an hour
[06:23] <mgedmin> thank you for your patience!
[06:31] <mgedmin> I know what needs to be fixed
[06:31] <mgedmin> bzr branch stiiil running
[06:32] <mgedmin> wheee, Vcs-Svn: svn://anonscm.debian.org/pkg-gnome/desktop/unstable/glib2.0/
[06:33] <mgedmin> does Debian link gdb against python 3?
[06:33] <mgedmin> no!  2.7
[06:37] <mgedmin> okay, bug still present upstream: https://github.com/GNOME/glib/blob/master/glib/glib.py#L61
[06:38] <mgedmin> woo, last commit was by darkxst \o/
[06:39] <mgedmin> ... bzr branch still running
[06:41] <mgedmin> suddenly I don't know if I should file a new bug or if it's ok to add more patches to https://bugzilla.gnome.org/show_bug.cgi?id=720635
[06:41] <ubot5> Gnome bug 720635 in general "Make gdb pretty-printers compatible with Python3" [Normal,Resolved: fixed]
[06:44] <mgedmin> git clone git://git.gnome.org/glib finished in 3 and a half minutes
[06:44] <mgedmin> bzr branch ubuntu:glib2.0 still running
[06:44] <mgedmin> (downloaded 670 megs so far!)
[06:44] <mgedmin> glib/.git is 52 MB
[06:45] <mgedmin> imagine what UDD could be if git had been invented a couple of years sooner
[06:46] <darkxst> https://git.gnome.org/browse/glib/commit/?id=7991178a752a22274950e54dc4f05b55ae54d756
[06:46] <mgedmin> the same kind of fix needs to be applied to glib.py too
[06:47] <darkxst> ok, file a new bug
[06:47] <darkxst> I do recall fixing some of those, but maybe was in mozjs or something
[06:47] <darkxst> launchpad just grew git support
[06:48] <mgedmin> bugzilla makes filing a new bug damn inconvenient :(
[06:48] <darkxst> for patches I use git bz
[06:48] <darkxst> http://blog.launchpad.net/general/git-code-hosting-beta
[06:49] <mgedmin> does git bz file bugs, or just upload attachments?
[06:49] <darkxst> can file bugs, attach, apply and push
[06:50] <mgedmin> neat!
[06:50] <darkxst> don't know if you can file a bug without a patch though
[06:50] <mgedmin> I don't suppose anybody packaged git-bz for Ubuntu?
[06:50] <mgedmin> of course not
[06:51] <darkxst> its only a simple shell script
[06:51] <darkxst> git://git.fishsoup.net/git-bz
[06:51] <darkxst> drop it somewhere in your path

[06:55] <mgedmin> has a patch
[06:55] <mgedmin> that I probably should have tested before uploading
[06:59] <mgedmin> yay it works
[07:03] <mgedmin> ok, back to the gnome-shell segfault
[07:03] <mgedmin> xrandr tells it monitors have changed, etc, etc
[07:03] <mgedmin> uh, this looks strange:
[07:03] <mgedmin> #14 0x00007fa9fbbd2e4a in g_signal_emit_by_name (instance=0x20, instance@entry=0x7562a0,
[07:03] <mgedmin>     detailed_signal=0x10 <error: Cannot access memory at address 0x10>, detailed_signal@entry=0x7fa9fd284c77 "monitors-changed")
[07:03] <mgedmin> 0x20?  0x10?  are those pointers?
[07:04] <darkxst> they are meant to be pointers
[07:06] <mgedmin> frame 3: g_list_prepend
[07:06] <mgedmin> info locals: new_list = 0x729990 = {0x7299a0, 0x66a4650, <error reading variable new_list (Cannot access memory at address 0x4)>
[07:09] <mgedmin> ah, it's executing new_list = _g_list_alloc ()
[07:10] <mgedmin> #0  magazine_chain_pop_head (magazine_chunks=0x7299b0) at /build/buildd/glib2.0-2.44.0/./glib/gslice.c:539
[07:10] <mgedmin> 539	      (*magazine_chunks)->data = chunk->next;
[07:10] <mgedmin> and chunk is 0xe000000000000000
[07:11] <mgedmin> "Cannot access memory at address 0xe000000000000000"
[07:17] <mgedmin> wow, apport in ubuntu has 829 open bugs
[07:25] <mgedmin> also, yeah, apport-retrace -g <crash file> is wonderful
[07:26] <mgedmin> I was complaining about the slow-and-wrong "let's download a bunch of debug debs and install them and then give you a useless backtrace" feature
[07:39] <mgedmin> now I know why apport is broken
[07:40] <darkxst> mgedmin, apport-retrace in the archives does not support ppa's
[07:40] <mgedmin> I'm talking about local apport
