Bug#717112: hang debugging ...

2013-07-25 Thread Michael Meeks
Hi there,

Can you install the relevant debuginfo packages, connect to libreoffice
and get some backtraces: 't a a bt' in gdb.

I suspect the thumbnailing piece myself, we do some call there that in
theory is magic (and all that) but it's some synchronous magic and I'm
suspicious of it. Looking forward to the trace.

Thanks ! :-)

Michael.

  OK, I'll try again with 4.0.1 (if I remember).
 
 It works for me in 4.0.1-rc1, thanks.  (Tested with Bluetooth only.)

Great ! thanks for testing :-) hopefully it's a cool feature to promote
LibreOffice with.

All the best,

Michael.

 What information do you need from me to debug this?

Heh - thanks so much for trying it out; it really is in a bit of a
state in 4.0.0 - a swathe of that stuff has been re-written for 4.0.1
and we're just working on getting that reviewed / in for 4.0.1rc1 - due
this week; with 4.0.1 due in ~2 weeks or so.

The wiki page has a long list of caveats for this version ...

Sorry about that,

Michael.

Bug#608732: stack trace ?

Great.

 to date, i can see a problem related to file locking:
 
 Program received signal SIGSEGV, Segmentation fault.
 __pthread_mutex_lock (mutex=0x1) at pthread_mutex_lock.c:50
 50pthread_mutex_lock.c: No such file or directory.
   in pthread_mutex_lock.c

Well - if you get a SEGV; we need to fix it - LibreOffice should never
SEGV.

 as my home dir is on nfs, i've turned FILE_LOCKING to no, with no visible
 difference. let me know where to continue.

different type of locking - can you give us the results of:

thread apply all backtrace ?

Thanks,

Michael.

If so wonderful; but we didn't fix anything in this area, that I'm

Thirded, and pushed to libreoffice-3-3-0

Thanks !

Hi there,

 i'd love to collect the backtrace, just be more instructive on the steps i
 should follow: needed packages, command lines etc.

First - it would be much appreciated if you could use the freedesktop
bug.

Second - can you confirm that you can actually install your extension
(move away your ~/.libreoffice first perhaps) - I cannot (I get errors
wrt. missing registration methods).

Third - if you get a crash you need to:

cd /path/to/libreoffice/program
gdb ./soffice.bin
r
# make it crash # :-)
thread apply all backtrace

and attach the backtrace - bonus points for having debuginfo packages
installed before you run it ;-)

If that shows memory corruption, then repeating with valgrind instead
of gdb:

valgrind --num-callers=25 ./soffice.bin 21 | tee /tmp/val-log

may give a more useful trace. In the meantime, it is hard to see the
bug (as is) as a blocker.

Thanks !

Michale.

Bug#608732: stack trace ?

2011-01-13 Thread Michael Meeks
Hi Alex,

I'm having trouble reproducing this; perhaps it is bugs on our side;
certainly installing the extension on master fails on install; I'm doing
a fresh 3.3.0 build now to test;

I was wondering; if you could run soffice.bin inside gdb - and get a
stacktrace from that (thread apply all backtrace) with debugging symbols
from your crash-on-exit.

We have fixed a number of memory leaks in 3.3, and sadly some code, off
the beaten path, may depend on the leaks still. Also - responses to the
freedesktop bugzilla much appreciated.

Thanks !

Michael.

Bug#604634: cause ?

2010-12-08 Thread Michael Meeks
It looks like the collector is still running for some reason; of course,
while it is running and has that proc filesystem open - it cannot be
unmounted. So I would look into why the collector is not quitting when
it should - we should kill it (or ptrace kill it I forget which - and
then it should die) ;-)

 (gdb) thread apply all backtrace

Ok - that's quite helpful. Probably the bug is more banal than a
complex threading problem: a simple memory corruption breaking the
(thread safe anyway) heap primitives.

Is there any chance you can install the cups and openoffice debuginfo
packages (so we get a better trace), and run it under valgrind [ this
will take a while ;-]:

cd /usr/lib/ooo3/program # [or Debian equivalent]
export OOO_FORCE_SYSALLOC=1
valgrind ./soffice.bin -writer 21 | tee /tmp/val-log

And send in /tmp/val-log ( probably best compressed unless you can
supress the runaway java nonsense ;-). Hopefully that will pin-point the
heap corruption to the line.

Many thanks,

Michael.

 It's only 34 KB. Attached.

Wonderful ;-) thanks for that - it seems to show the bug in an
interaction with freetype:

==21743== Invalid read of size 8

(in /usr/lib/libfreetype.so.6.6.0)

GlyphData) const (in /usr/lib/openoffice/basis3.2/program/libvcllx.so)
..
==21743==  Address 0x18 is not stack'd, malloc'd or (recently) free'd

which triggers the segv handler:

==21743== Conditional jump or move depends on uninitialised value(s)

==21743==by 0x5C771DF: ??? (in /lib/libc-2.11.2.so)
..

Unfortunately, you didn't install the debuginfo symbols [ or you are
using some architecture valgrind can't unwind ]. 

Any chance you can install the freetype and OO.o debuginfo and get
another valgrind trace ? [ Rene what packages / commands would Vincent
need for that ] ?

Thanks,

Michael.

 Is it possible to disable things related to cups, to see if this
 solves the problems (since the authentication dialog is something
 new)?

I'm rather surprised to see this main-loop, and spell-check stuff
running from another (the CUPS polling) thread - and I'm surprised at
the suggestion that CUPS might be thread-safe.

We really need a trace from all threads if that's possible:

thread apply all backtrace

in gdb :-)

Thanks,

Michael.
