This blocks the pandas 2.2 transition, as that breaks older statsmodels
versions.

[Bug 1987181] Re: test_attach_to_pid* fails

[Rebecca Palmer]

** Summary changed:

- FTBFS - test_attach_to_pid* fails
+ test_attach_to_pid* fails

** Description changed:

+ (Edit: now only 3, and no longer an FTBFS but that's because the failure
+ is being ignored)
+ 
  On Ubuntu, but not the same package in Debian, all 5 variants of
  test_attach_to_pid* fail with
  
  stderr: b'Could not attach to process.  If your uid matches the uid of
  the target\nprocess, check the setting of
  /proc/sys/kernel/yama/ptrace_scope, or try\nagain as the root user.  For
  more details, see /etc/sysctl.d/10-ptrace.conf\nptrace: Inappropriate
  ioctl for device.\nTarget \'None\' cannot support this command.\nNo
  symbol table is loaded.  Use the "file" command.\nNo symbol table is
  loaded.  Use the "file" command.\n'
  
  or something similar.
  
  This appears to affect all pydevd versions on all architectures (the
  riscv64 build "succeeds" because it's nocheck), though I haven't checked
  whether the error has always been that one.

[Bug 2060811] Re: FFe updating lxml to the 5.2.1 release

[Rebecca Palmer]

"this change will need minor changes in two depending packages."
probably refers to the packages that do use lxml-html-clean now needing
to either stop doing so or explicitly depend on it
(https://bugs.debian.org/1068349).

This has been done in nbconvert (and hence documentation builds of e.g.
pandas) and readability, but as listed in that bug, these are probably
not the only two such packages.

[Bug 2064928] [NEW] Please merge cython 3.0.10+dfsg-5 from Debian unstable (main)

[Rebecca Palmer]

Public bug reported:

(Caution: I'm the maintainer of statsmodels but not cython3, and have
*not* checked whether this would actually work.)

statsmodels 0.14.2 is currently unable to build because it build-depends
on cython3 (>= 3.0.10~), which Debian has but Ubuntu has not.

The Ubuntu change (Drop python-numpy build-dependencies on i386) still
appears to be needed, so this will need to be a merge not a sync.

[Bug 1905340] Re: Add patch for Comet Lake support

[Rebecca Palmer]

Upstream beignet is dead, and replaced by intel-opencl-icd.

I also don't have that hardware.  I've sent a request for testing, but nobody 
has replied yet:
https://lists.freedesktop.org/archives/beignet/2020-November/date.html

I don't intend to enable them by default without testing, because I
consider "gives wrong answers" to be worse than "explicitly fails".
Enabling them only with some environment variable set is an option.

It is also fairly likely that beignet will be removed from future
Debian/Ubuntu releases because it doesn't work with LLVM 10+.

[Bug 1902857] Re: beignet error on haswell GPU

[Rebecca Palmer]

"error, type is 4592, error status is -5" is a rather generic error:
those codes are CL_OUT_OF_RESOURCES (on the GPU) during
CL_COMMAND_NDRANGE_KERNEL (a normal OpenCL computation).  The other
error message ("Input/output error") doesn't match, so this probably
_isn't_ 100639 ("Device or resource busy") or a simple out-of-memory
("No space left on device").

It _might_ be https://bugs.freedesktop.org/show_bug.cgi?id=91525 (which
doesn't have the second message, but it only appears if beignet was
compiled with debugging messages enabled).

I'm not sure what to try next.

(beignet is dead upstream, and may be removed from future Debian/Ubuntu
along with llvm-toolchain-9, as it doesn't work with llvm-toolchain-10.
Its replacement is intel-opencl-icd, but that requires newer hardware
than yours.)

Please try running the tests (install the beignet-dev package, then

If this doesn't trigger the bug, do you have a way to do so that doesn't

flightgear 2019.1 was removed because it didn't build with the new
openscenegraph (bug 1883713).

flightgear 2020.1 was then uploaded, which fixed this bug but FTBFS on
s390x (Debian https://bugs.debian.org/963201).  Because of this, it is
held in -proposed (https://people.canonical.com/~ubuntu-archive

flightgear could be removed on s390x.

[Bug 1849374] Re: packages built for python3.8 with disabled tests, for a first binary

[Rebecca Palmer]

The python-xarray version in -proposed appears to already have these
fixes, but it's instead broken because it expects a newer dask
(test_dask), and on arm*, by long-standing numpy bug
https://bugs.debian.org/877754 (test_datetime_reduce).

The dask version in -proposed appears to fix its pandas 0.25 issues but
be broken by pytest 4: it's apparently trying to write to a temporary
directory that doesn't exist (test_rearrange +
test_temporary_directory).

This suggests the solution to these two is:
- point dask test_rearrange + test_temporary_directory to somewhere that does 
exist (and is writable by tests)
- xfail python-xarray test_datetime_reduce
- attempt pandas + dask + python-xarray together

snakemake hang: would it be worth retrying this to check if it always
hangs / if it's always the same test?

python-feather-format: has a patch in https://bugs.debian.org/943925,
but note that the Breaks: ends with the next upload to *Debian*, not
solely to Ubuntu

[Bug 1849374] Re: packages built for python3.8 with disabled tests, for a first binary

[Rebecca Palmer]

On the pandas autopkgtest failures:

cnvkit, python-feather-format, python-skbio, and q2-types (plus its rdep
q2-cutadapt) are the expected ones, that the package has explicit Breaks
for.

dask, python-xarray and snakemake are unexpected.  (They weren't seen in
Debian experimental because the first two were already broken in Debian
and the last is on an architecture Debian doesn't test.)

snakemake is a hang (timeout in something that takes <30min everywhere
else).

xarray is 3 failures: 2 look readily fixable (just remove the attempts
to use pd.Panel), the 3rd looks like complaining about a new warning.

I haven't looked at dask carefully enough to have an opinion.

[Bug 1851892] [NEW] Sync statsmodels 0.10.1-2 (universe) from Debian experimental (main)

[Rebecca Palmer]

Public bug reported:

(only just uploaded, so you might not see it yet)

This is in experimental because it removes Python 2 support before
Debian-unstable's rules allow; this is not an issue here as the Ubuntu
version has already dropped it.

Overriding the Ubuntu changes, as they are no longer needed:

The functionality of 1+5 (drop python2) and 4 (fix flaky test) is now
included in the Debian package.

2+3 (set --doc-main-package) I intentionally chose not to do: if we
think it's a bug that debhelper doesn't recognize python-$x-doc ->
python3-$x, I suggest fixing that in debhelper, not ~600 individual
packages.  https://lists.debian.org/debian-python/2019/07/msg00044.html

[Bug 1849374] Re: packages built for python3.8 with disabled tests, for a first binary

[Rebecca Palmer]

pandas will probably need an upgrade to upstream 0.25: see
https://bugs.debian.org/931557 for progress on that.

[Bug 1819227] [NEW] KalmanFilter gives wrong results on armhf

[Rebecca Palmer]

Public bug reported:

Test log:
https://autopkgtest.ubuntu.com/packages/statsmodels/disco/armhf

(This is probably *not* a regression: upstream tests weren't run in
0.8.0-7.)

As noted in the changelog, I attempted to disable this feature on armhf
as I'd rather have an explicit error than silent nonsense.  However, as
it was an arch-specific patch applied at build time to a part of the
package that is arch:all, it made the build-time tests pass but didn't
actually do anything to the as-installed package.

[Bug 1787280] Re: python3-pandas-lib missing in armhf version

[Rebecca Palmer]

('Fix Released' = 'fixed in current development, i.e. disco'.  If you
think this should also be fixed in bionic, see
https://wiki.ubuntu.com/StableReleaseUpdates )

The -lib is missing because pandas failed to build at all on bionic
armhf, with what looks like a crashing test:
https://launchpad.net/ubuntu/+source/pandas/0.22.0-4/+build/14787301.
(The non-lib package is there because it is arch:all, i.e. all
architectures use the same package.)

This was fixed in 0.22.0-7, probably by https://salsa.debian.org

Additional information (note in particular that Intel consider the
graphics development branch at https://cgit.freedesktop.org/drm-tip, not
the integration branch at kernel.org, to be the appropriate "latest
upstream" to test against):

https://01.org/linuxgraphics/documentation/how-report-bugs

And yes, self-built kernels won't work on hardware/BIOSes that require

[Rebecca Palmer]

('invalid' = 'not beignet's bug' - I do agree it is *a* bug)

The kernel code that reads these numbers from the device
(https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/gpu/drm/i915/intel_device_info.c#n434)
does explicitly support the 47 EU case (any one of the 48 faulty and
disabled), and has nothing obviously wrong with it.

If you want to take this further, my suggested next step is:
- get the latest upstream kernel 
(https://wiki.ubuntu.com/KernelTeam/GitKernelBuild)
- add #include  and lots of debug printk()s to the above 
broadwell_sseu_info_init function (printk() not printf(), and  under 1024 bytes 
per message, as this is kernel code - 
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/kernel-hacking/hacking.rst#n234)
- compile (will probably take several hours) and boot into that
- see if the issue still exists, and if it does, check /var/log/kern.log for 
the debug messages you added

Here is enough.  (It's probably in beignet, not dpkg-buildpackage, and not new: 
packages for distribution are built in minimal chroots, so there wouldn't have 
been a python2 to trigger this bug in official builds.)

[Bug 1800752] Re: Performance degraded in Cosmic

[Rebecca Palmer]

Well spotted - BOINC "GFLOPS peak" is the theoretical 8 * compute units
* max clock (not an actual speed measurement), and matches the 24
compute units clinfo reports, not the 48 compute units this GPU is
supposed to have.

Beignet can take this value from an internal hardcoded list (in
src/cl_device_id.c, which says 48 for this GPU), but by default it
prefers to ask the kernel.

This change should both confirm that that's where the 24 is coming from,
and change it back to 48 to allow testing whether this is the source of
the slowdown (warning: untested, might crash/hang the system):

Was this report sent from the affected system?  as it says the CPU is an
i5-2500K, which is too old for beignet.  (It shouldn't crash, but won't
be running the computations, so the slowdown is probably from some other
package.)

Please post the output of clinfo (from the clinfo package).

[Bug 1354086] Re: [i5-3230] Tight pyopencl.clmath loops cause out-of-memory system hang

[Rebecca Palmer]

There are actually three separate issues here, but as (a) is already
known and (b) is not a bug, I define this bug to be (c).

To understand them, it is necessary to know that OpenCL computations are
asynchronous: a clmath expression like "aCL=bCL+cCL" places this
operation in a CommandQueue and returns without waiting for it to
finish.  (This is to allow the CPU to do other work during the GPU
computation.)

(a) Running out of memory can hang the entire system, rather than ending
just the OpenCL application with CL_OUT_OF_RESOURCES.

This is probably the same long-standing issue (e.g. bug 620074, bug
1504914, bug 1592813) that makes Linux out-of-memory conditions in
general do this.  (The integrated GPUs supported by beignet share the
host's memory.)

(b) In both beignet and pocl (probably all ICDs), a long sequence of
allocate/deallocate operations (e.g. clmath creating a new array each
operation) *without* waiting for results uses up memory, but regularly
waiting for results avoids this.

This is because allocating memory (clCreateBuffer) happens immediately,
but the actual computations are queued, and memory can't be freed until
the computations using it have finished.  Hence, if many operations are
queued without waiting for a result, memory allocation can run far ahead
of computation, filling up the memory.

This is not a bug: don't do that.  Either wait for results often enough
that this doesn't build up to the point of running out of memory, or
(better for performance) re-use existing memory objects instead of
allocating/deallocating.  (To do the latter with clmath, use
pyopencl.tools.MemoryPool.)

While investigating this I discovered that all beignet queues are out-
of-order execution even if the user requested in-order, which is a bug,
but is not the cause of this issue.

(c) In beignet but not pocl, a long sequence of clmath operations leaks
memory, even with regular waits.

To ensure that intermediate results are calculated before they are used,
clmath arrays use Event objects to track dependencies.  A beignet event
includes references to the event(s) it depends on
(https://sources.debian.org/src/beignet/1.3.2-2/src/cl_event.h/?hl=47#L40),
and continues to hold these as long as the event object exists, even if
it has completed and been waited for.  As OpenCL objects are freed by
reference counting, this means that as long as the last event in a
dependency tree exists, the whole tree of (recursive) dependencies also
exists, taking up memory (~20kB per event).

pocl avoids this by dropping these references after completion (
https://sources.debian.org/src/pocl/1.1-5/lib/CL/devices/common.c/?hl=722#L714
); the attached patch makes beignet do so.  Checking the source suggests
mesa is also affected (
https://sources.debian.org/src/mesa/18.1.3-1/src/gallium/state_trackers/clover/core/event.hpp/?hl=84#L34
), but I don't have the hardware to try it.  (The OpenCL part of mesa is
AMD/Radeon only.)

[Bug 1776867] Re: OpenCL-beignet EnqueueNDRangeKernel fails after multiple execution with error -5

[Rebecca Palmer]

It would have eventually, if you'd run more iterations: each iteration
leaks ~450 bytes before
https://cgit.freedesktop.org/beignet/commit/?id=7ae1517cfc373847f168ffb3e41b635861af19c7
but ~20,000 bytes after.  I suspect the reason for this is that events
no longer release exec_data.gpgpu on completion (cl_enqueue.c part of
that commit), to allow profiling timestamps to be read from it.

If you want a RAII interface, use opencl-clhpp-headers.  (Or in theory
pyopencl, but bug 1354086 also looks like an event object leak...)

[Bug 1776867] Re: OpenCL-beignet EnqueueNDRangeKernel fails after multiple execution with error -5

[Rebecca Palmer]

The bug is technically in your code: as you never call clReleaseEvent
(waiting on an event doesn't release it), you leak an event object per
iteration.  I suspect the beignet change exposed this bug by greatly
increasing the effective size of an event object, but don't yet know
how.

There is a C++ interface to OpenCL (opencl-clhpp-headers) which may make
this easier.

[Bug 1776867] Re: OpenCL-beignet EnqueueNDRangeKernel fails after multiple execution with error -5

[Rebecca Palmer]

Memory consumption rises over a run, by ~2GB by the failure point.  The
exact number of iterations before failure depends on the beignet version
but not the matrix size.

git bisect finds that this was introduced by

https://cgit.freedesktop.org/beignet/commit/?id=7ae1517cfc373847f168ffb3e41b635861af19c7

(between 1.2.x and 1.3.x).  However, this is a large commit and trying
to revert it on 1.3.2 fails with conflicts, so this doesn't provide an
immediate way to fix the problem.

As a workaround, it is probably possible to compile beignet 1.2.x from
source in Ubuntu 16.04 (use LLVM/Clang 3.8), but I haven't tried this.

Public bug reported:

(If your build servers don't update immediately you might need to wait a
bit - sphinx 1.7.5-1 had a bug that made this FTBFS (Debian #901662),
and 1.7.5-2 has only been available for ~7 hours.)

The Ubuntu change is now part of the Debian package (the second point
below).

theano (1.0.2+dfsg-1) unstable; urgency=medium

  * New upstream release.
  * Split up the test suite to avoid running out of memory
(workaround for #898126 / LP#1769672), but don't hide output.
  * Rebuild doc/library/d3viz/*.html, and tell Lintian where their
source is.
(This is unreproducible as some of them contain profiling output,
but we're unreproducible anyway due to uglifyjs.)

[Bug 1769672] Re: FTBFS on arm64+ppc64el - out of memory

[Rebecca Palmer]

The underlying issue is not new; I don't know whether it's got worse per
test or the test suite has just got longer.  See the linked Debian bug
for further analysis.

This will probably make it build (by splitting up the test suite, i.e.
it doesn't solve the underlying problem) but I haven't had time to test
it.

[Bug 1769672] Re: FTBFS on arm64+ppc64el - out of memory

[Rebecca Palmer]

Looks like it's a cumulative memory leak: over the python2 tests, memory
usage increases by ~6GB.  (Measured by occasionally looking at System
Monitor, so I know it's more than one step, but not whether it's a few
bad tests or a smaller amount on every test.)  This is then freed when
the python2 tests finish; I didn't wait to see whether the python3 half
would repeat it.

This suggests that a quick workaround would be to split the test suite
into several batches: upstream actually provide a tool to do that
(theano/tests/run_tests_in_batch.py), though they seem to think the need
for it is Windows-specific.  However, this would be hiding a real bug if
the memory leak can also happen in normal use of Theano.

Debian defaults to parallel builds in dh compat>=10 (theano sets this to
11), but System Monitor shows theano's tests using ~1 core of CPU.  I
suspect this is because Theano uses a custom test runner script (with
nearly the same interface as nosetests, but dh doesn't know that).  I
also vaguely remember considering parallel testing in a previous release
and deciding/finding it wouldn't be a good idea, but can't remember why.

[Bug 1769672] [NEW] FTBFS on arm64+ppc64el - out of memory

[Rebecca Palmer]

Public bug reported:

The build logs show 16 tests running out of memory on arm64 [0] and 57
on ppc64el [1].

How much is too much, and is it a set maximum or dependent on what else
the buildd is doing?  A first attempt at running the same tests locally
(Debian amd64, python3) gave ~300MB memory usage.

The failed tests are towards the end, which suggests the possibility of
a cumulative memory leak, but the PPA [2] and the original fail on
exactly the same number of tests.

[Bug 1683512] Re: No libcuda.so.1 after upgrading to 381-driver

[Rebecca Palmer]

('invalid' as in 'not our (theano's) bug')

Where did you obtain nvidia-381 (Ubuntu itself went straight from -375
to -384)? the Nvidia website? a PPA?

nvidia-graphics-drivers-384 is now available in xenial-updates: is that
any better?

(libcudata.so.8 is probably a different library, not the file you want.)

included in the Debian package.

beignet (1.3.1-1) unstable; urgency=medium

  * New upstream release.
  * Drop patches applied upstream, refresh others. 
  * Explicitly specify LLVM 3.9/3.8, as we no longer need to match
mesa (#848368 has been fixed) and this package FTBFS with LLVM 4.0.
(Closes: #871332)
  * Remove CAN_ENABLE_OPENCL2, as upstream now handles this.
  * Use compat 10, remove now-default --parallel.
  * Use https copyright-format, Priority: optional and support nodoc

Switching to llvm-dev/libclang-dev (which are 4.0) does fix this crash

Rebuilding kdevelop against LLVM 4.0 (via the obvious change to
debian/control) avoids this crash; it still fails to create the project
(with "please see the Version Control toolview" even though I left
Version Control at the default None), but I suspect that's an unrelated
"doesn't really work in a minimal chroot" issue.

[Bug 1668024] Re: FTBFS in -proposed

[Rebecca Palmer]

Debian beignet automatically uses the same LLVM version as mesa, to
avoid crashing when OpenCL and OpenGL are used together (as LLVM lacks
symbol versioning - https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=848368#46 ).  Ubuntu -proposed mesa now uses LLVM
4.0, which beignet isn't compatible with (adding the dependency only
makes it fail later), so this no longer works.

The immediate fix is to disable this mechanism and use LLVM 3.9, as
attached.  (This will have the above bug if LLVM 4.0 mesa is let out of
-proposed, but so would the existing beignet, built with 3.9 before mesa
switched.)

[Bug 1642887] Re: Request beignet upgrade to 1.2.1

[Rebecca Palmer]

The Debian package of 1.2.1 is in Alioth awaiting sponsorship; once
uploaded there it will automatically be imported to Ubuntu zesty
(current development), but not existing releases.

This might work in 16.04, but has *not* been tested:

git clone https://anonscm.debian.org/cgit/pkg-opencl/beignet.git
cd beignet
sudo apt-get install build-essential debhelper cmake libgl1-mesa-dri clang-3.8  
libclang-3.8-dev  llvm-3.8-dev ocl-icd-dev  ocl-icd-opencl-dev  pkg-config

#-d because clang-3.9 isn't available or needed in xenial
dpkg-buildpackage -us -uc -d
sudo dpkg -i beignet*.deb

I don't see any reported 1.2.0 -> 1.2.1 regressions on the upstream

regression, but zesty and Debian already have 1.2.0.

[Bug 1443528] [NEW] FFe: Sync simgear 3.4.0-1~exp1 (universe) from Debian git, flightgear 3.4.0-0~exp2 (universe) and flightgear-data 3.4.0+dfsg-0~exp2 (universe) from Debian experimental (main)

[Rebecca Palmer]

*** This bug is a security vulnerability ***

Public security bug reported:

These packages contain bug fixes, including 2 security fixes (
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=780712
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=780716 ).

None of these packages have any real Ubuntu changes: simgear has an
Ubuntu version number only because it was synced from Alioth.  This will
be needed again ( http://anonscm.debian.org/cgit/collab-
maint/simgear.git/log/?h=experimental ) as simgear 3.4.0 is still in the
Debian NEW queue.

Build and test logs attached.

[Bug 1434814] Re: FFe: Sync beignet 1.0.2-1 (universe) from Debian experimental (main)

[Rebecca Palmer]

This version was intended as a normal unstable upload (not really
experimental, but also not intended to be synced under freeze): while
the new upstream happens to be a bug fix release, the packaging changes
aren't so restricted.

However, I'm not aware of it causing any problems in Debian, so if you
prefer to sync it anyway, go ahead.

As nobody has been able to test this in flightgear, assuming it's the

[Bug 1368801] Re: libcitygml ftfs with new openscenegraph

 there's probably more work to be done for the openscenegraph
migration?

ossim, osgearth and openwalnut need rebuilding (but probably no actual
changes, given Debian's experience).

[Rebecca Palmer]

That's not the version of simgear I asked for: we're skipping over 3.2
and going straight to 3.4, but due to NEW queue delays this is only in
Debian git, not Debian main archive.

The install failure looks like you built it on a system with -proposed
enabled then tried to install it with -proposed disabled, which failed
because openscenegraph is currently changing soname
(https://launchpad.net/ubuntu/+source/openscenegraph).  When we did that
transition in Debian it was a straightforward rebuild, but on Ubuntu it
appears to be blocked by libcitygml being broken (
http://people.canonical.com/~ubuntu-archive/proposed-
migration/update_excuses.html

The libcitygml breakage has already been fixed in Debian (as
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=763047 ), so syncing
that package and rebuilding openscenegraph's other dependencies should
fix that problem.

[Bug 1368801] Re: libcitygml ftfs with new openscenegraph

[Rebecca Palmer]

dholbach's test builds appear to have been without -proposed as they
used libopenscenegraph99, which isn't multiarch (the
libopenscenegraph100 in -proposed is), but I don't have any other theory
for where the 19 comes from.

If it is multiarch-related, the fix would be to replace the
libopenscenegraph[0-9]*:.*\s*install pattern with
libopenscenegraph[0-9]*[:\s].*install

[Rebecca Palmer]

I can't reproduce this problem: on my system (dpkg-buildpackage -b with
fakeroot, in amd64 vivid+vivid-proposed chroot on Debian kernel) it
builds successfully (log attached).

I also don't see where the 19 1 can be coming from (unlike the 0~rc1
in the vaguely similar https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=719396 ); the below debian/gencontrol was meant to
find out, but that requires a system where the bug happens.

[Bug 1368801] Re: libcitygml ftfs with new openscenegraph

[Rebecca Palmer]

That confirms that the problem is on the first line (i.e. LIBOSG_SHARE
is being set to the empty string), but means it isn't related to the
presence or absence of a multiarch suffix.

The version numbers that end up in LIBOSG_VERSION appear to be only
packages that are in the base/build-essential system (eg. gcc), as
opposed to the ones installed as build-dependencies of libcitygml itself
(eg. the libopenscenegraph100 this script is trying to find): is that
all that dpkg --get-selections and/or dpkg -l list in an Ubuntu buildd
setup?

The simple solution would be to stop trying to autodetect the version
and hardcode LIBOSG_SHARE=libopenscenegraph100, LIBOSG_VERSION=3.2.1,
and (to fail the build if we forget to update these) a Build-Depends:
libopenscenegraph100 ( 3.2.2~) with a see debian/gencontrol comment.

[Rebecca Palmer]

Thanks.

The connection to libcitygml is that libopenscenegraph100 and all its
dependencies (including ones that are themselves OK, such as these
packages) can't leave -proposed yet, because doing so would break the
old libcitygml: https://wiki.ubuntu.com/ProposedMigration

I have posted some suggestions in bug 1368801, but can't reproduce the
bug to test them.

[Bug 1368801] Re: libcitygml ftfs with new openscenegraph

[Rebecca Palmer]

A guess at what's going on: the first line of gencontrol is failing to
find libopenscenegraph100 (possibly because the grep pattern assumes
dpkg --get-selections will include the :arch suffix; does it do that if
multiarch isn't on?), and the second line is hence extracting the
version numbers of _everything_ installed.

[Bug 1354086] Re: [i5-3230] Tight pyopencl.clmath loops cause out-of-memory system hang

[Rebecca Palmer]

** Summary changed:

- [i5-3230] Crash/hang/graphical artifacts in pyopencl
+ [i5-3230] Tight pyopencl.clmath loops cause out-of-memory system hang

** Description changed:

- pyopencl is partly or wholly unusable on an Intel i5-3230 integrated
- GPU:
+ In beignet (not pocl), tight loops involving OpenCL array creation and
+ destruction, eg. repeated bCL=aCL+bCL (or other pyopencl.clmath
+ operations) or repeated pyopencl.enqueue_copy(cq0,bCL.data,aCL.data),
+ often hang the whole system, after a number of operations consistent
+ with memory exhaustion.
  
- beignet 0.3 (trusty default):
- pyopencl.elementwise.ElementwiseKernel draws dotted stripes across the 
screen, and gives wrong results
- pyopencl.clmath segfaults Python
+ As waiting for queued operations to finish
+ (pyopencl.enqueue_barrier(cq0).wait()) before attempting more avoids the
+ bug, but dependencies between the operations (as in the bCL=aCL+bCL
+ example) do not, this is probably a result of the allocate memory step
+ being separate from, and faster than, the do the operation step, so
+ being able to run ahead until it uses up all the memory.
  
- beignet 0.8 (utopic source, recompiled in trusty) and 0.9 (upstream git head):
- pyopencl.elementwise.ElementwiseKernel works
- pyopencl.clmath hangs the entire system (screen frozen, any playing sounds 
repeating in ~0.5sec loop, requires Alt+SysRq+b reboot; System Monitor shows no 
abnormal memory usage before the hang, but I don't know if it counts GPU memory)
- 
- To reproduce: python pocl_test.py
- 
- I'm guessing this is a beignet rather than pyopencl bug, as pyopencl
- worked on my previous (nvidia) system and a normal application shouldn't
- be able to hang the whole system.
- 
- ProblemType: Bug
- DistroRelease: Ubuntu 14.04
- Package: beignet (not installed)
- ProcVersionSignature: Ubuntu 3.13.0-32.57-generic 3.13.11.4
- Uname: Linux 3.13.0-32-generic x86_64
- ApportVersion: 2.14.1-0ubuntu3.2
- Architecture: amd64
- CurrentDesktop: Unity
- Date: Thu Aug  7 17:18:35 2014
- EcryptfsInUse: Yes
- InstallationDate: Installed on 2014-08-01 (6 days ago)
- InstallationMedia: Ubuntu 14.04.1 LTS Trusty Tahr - Release amd64+mac 
(20140722.2)
- SourcePackage: beignet
- UpgradeStatus: No upgrade log present (probably fresh install)
+ (Note that while the above wait() can be used as a workaround for this
+ bug, it is usually faster to avoid frequent memory allocation
+ altogether, by reusing existing arrays; for pyopencl.clmath, this means
+ using pyopencl.tools.MemoryPool.)

[Bug 1227365] Re: grub does not appear when holding down shift key

[Rebecca Palmer]

The original bug (which I no longer have the hardware from) was on BIOS;
should the EFI problem be a separate bug?

Does changing the timeout settings to always-show (see above) work on
EFI?

 I need the GRUB menu because I need to add 'nomodeset'

There's a GRUB_CMDLINE_LINUX parameter in /etc/default/grub that you can
use to add that permanently, but given that updates made there only take
effect after running 'sudo update-grub', if you're doing this from a
liveCD you'll also need to add it directly to the command line (the
first one starting with 'linux') in /boot/grub/grub.cfg.

 so the [...] nouveau driver doesn't attempt to drive my modern nvidia
card so I can get more than just a blank screen

Your real problem might be bug 1315156: there's a workaround there, but
it requires a running system.

[Bug 1402418] Re: package flightgear-data-base (not installed) failed to install/upgrade: no se pudieron copiar los datos extraídos de './usr/share/games/flightgear/Textures.high/Terrain/countryside3.

[Rebecca Palmer]

This is probably a hardware (disk or memory) problem, not a bug (the log
contains dpkg-deb (subproceso): descomprimiendo el miembro del archivo:
error de lzma: los datos comprimidos están corrompidos = dpkg-deb
(subprocess): decompressing archive member: lzma error: compressed data
is corrupt); hence, I am closing it.

sudo apt-get clean then retrying the install should fix the package,
but be aware that the faulty hardware may be corrupting other data on
the system. You can use memtest86+ on the boot menu to test memory.

[Bug 1079011] Re: stellarium assert failure: nv10_state_fb.c:50: get_rt_format: Assertion `0' failed.

[Rebecca Palmer]

The error occurs because nv10 (the driver used for this card) declares
VBO support (extension GL_ARB_vertex_buffer_object) but only supports
VBOs of int8, int16 and float (not double) types, and the application is
trying to draw data of type double.  Given that the double type is part
of the OpenGL spec, that would appear to be a bug in mesa, not the
application.

The easy fix would be don't declare VBO support on those cards, but
that would slow down many other applications, and break any that require
this feature.

An alternative would be a software fallback that reads back the VBO data
and draws it as either a client-side array or individual primitives
(which would probably be even slower, but only applications that
actually use doubles would take the penalty), but that might be more
work than is reasonable to do for little benefit: stellarium and other
QtOpenGL applications will lose OpenGL 1 support in the upcoming Qt 5
transition anyway, and flightgear would probably be unusably slow on
such old hardware even if it didn't crash.

As an immediate workaround, you can use software rendering with
LIBGL_ALWAYS_SOFTWARE=1 stellarium
(perhaps the error message should suggest that?), but expect that to be slow.

I will report this upstream.

[Bug 1079011] Re: stellarium assert failure: nv10_state_fb.c:50: get_rt_format: Assertion `0' failed.

[Rebecca Palmer]

Sorry, upstream explicitly don't want bug reports for cards older than
nv30 (yours is nv18, current is ~nv120):
http://nouveau.freedesktop.org/wiki/MesaDrivers/

Changing the error message (at
http://sources.debian.net/src/mesa/10.3.2-1/src/mesa/drivers/dri/nouveau/nv10_render.c/#L104
) to something more useful, e.g.

-  assert(0);
+  assert(0  This application requires GLdouble vertex buffers, which your 
graphics card does not support.  Try software rendering 
(LIBGL_ALWAYS_SOFTWARE=1 application).);

is probably about all that is reasonable to do as a Debian/Ubuntu patch.

[Rebecca Palmer]

(Sorry about the repeated questions: that's the nature of debugging a
problem that only happens on hardware I don't have.)

That looks like either a bad GLcontext (at the error location it is only
looking at this internal structure, not the objects to be drawn), or an
attempt to use VBO (an OpenGL 1.5 feature) on an OpenGL 1.2 card.

Can you try this, preferably in a terminal with unlimited scrollback (Edit  
Profile Preferences  Scrolling) as there may be a lot of output:
$ sudo apt-get install libqt4-dbg mesa-utils
$ glxinfo 
$ gdb --args stellarium
(gdb) run
[wait for crash, Alt+Tab back to terminal]
[all this is at the (gdb) prompt, writing it without prompts so you can cut and 
paste it]

 stellarium: 
 ../../../../../../../src/mesa/drivers/dri/nouveau/nv10_render.c:104: 
 get_hw_format: Assertion `0' failed.
That also appears to mean invalid format, so is probably the same bug.

 For whatever it's worth, I did the routine you described. The Stellarium 
 startup screen appeared but didn't disappear.
That's expected when something crashes under a debugger: please switch back to 
the debugger window (Alt+Tab), type thread apply all bt full and post the 
output.  (You can then close the debugger and program with quit.)

The attachment gdbfgfs is a gdb command list, not a backtrace, which

actual backtrace (i.e. the _result_ of running those gdb commands),

[Rebecca Palmer]

That message means invalid/unsupported buffer format (
http://sources.debian.net/src/mesa/10.3.2-1/src/mesa/drivers/dri/nouveau/nv10_state_fb.c
), and as it appears to refer to an internal nouveau buffer rather than
a passed-in texture, I suspect this is actually a mesa/nouveau bug.

As I do not have the hardware to test this myself, please do (in a
terminal):

$ sudo apt-get install libgl1-mesa-dri-dbg gdb
$ gdb --args fgfs
[or gdb --args stellarium, whichever is easier to reproduce the crash in]
(gdb) set pagination 0
(gdb) run
[wait for crash]

and post the ouput here.

This isn't a flightgear bug, it's an apt/ubuntu-release-upgrader bug,
and according to #8 is already fixed (in later releases, obviously this
won't help 12.04 - 14.04).

Removing flightgear and reinstalling it after the upgrade should be fine
as a workaround, since flightgear would be being upgraded anyway.

[Bug 1392737] Re: Missing cl_egl.h

[Rebecca Palmer]

This was because prior to 1.2-svn26009 the package used an explicit list
of what files to include ( http://sources.debian.net/src/khronos-opencl-
headers/1.2-2013.06.28-2~bpo70%2B1/debian/rules/#L14 ) which did not
include cl_egl.h; this has now been fixed.

As this package has no dependencies, installing the Vivid 1.2-svn26009
package in Trusty will probably work.

These functions are still available in OpenGL 4 compatibility contexts
