Guiseppe, any suggestions how to debug this?

the only optimization I am aware of that could cause a similar issue is
the delayed IPC namespace cleanup.  That would cause the IPC namespace
creation to fail though, not posix_spawn.

If you believe the failure can be related to reaching the pids limit for
the cgroup, could you please check the actual limit inside the
container?  You could check the value of /sys/fs/cgroup/pids.max inside
the container (assuming cgroupv2 and a cgroup namespace for the container).

Please let me know if that helps.

(replying for the benefit of the list)

Than: could you try some chromium builds with a cat of that value at
various points? (ie, prep, build, etc?)


Hi Kevin

i tried chromium build with a cat of that value. The value of 
/sys/fs/cgroup/pids.max is *max* at %prep, %setup and %build

The chromium build failed again with errors:

* Kevin Fenzi:


Greetings.

We are running into some anoying limits on koji builds of chromium.

First, since a long time ago, the koji.service file we are using has:

TasksMax=infinity

But yet, chromium was failing, seemingly hitting a task limit.
"ninja: fatal: posix_spawn: Resource temporarily unavailable"
in the build and:
"kernel: cgroup: fork rejected by pids controller in
/machine.slice/machine-7d12b2e6dcfb4230b04d2c2c0b499171.scope/payload"
on the builder.

Investigation and some help from folks in the #devel room
(many thanks glb!)
Showed that the systemd-nspawn container mock started has:

systemctl show systemd-nspawn@0b3f01a2a8e345a389b30c477812c471
TasksMax=16384

So, I put in place a:
/etc/systemd/system/systemd-nspawn@.service.d/override.conf
with:

[Service]
TasksMax=infinity

and that seemed to be used for the mock systemd-nspawn containers.

However, the builds with lots of cpus is now failing later with:

Error: spawn /usr/bin/node-18 EAGAIN
     at Process.ChildProcess._handle.onexit
(node:internal/child_process:283:19)
     at onErrorNT (node:internal/child_process:476:16)
     at processTicksAndRejections (node:internal/process/task_queues:82:21)
[!] Error: unfinished hook action(s) on exit:

Is there yet another layer here that has another limit?

Is there anything here I can set that says "infinity all the way down' ?

Assistance welcome. I can file a systemd bug, but I am not sure
this is a bug more than a lack of documentation.

It could be an old kernel bug:

   Task exit is signaled before task resource deallocation, leading to
   bogus EAGAIN errors
   <https://bugzilla.kernel.org/show_bug.cgi?id=154011>

There have been recent namespace optimizations which introduce a similar
pattern there.  While they improve throughput in many cases, continuous
allocation and deallocation can now fail, even though the program logic
ensures that resources are never exceeded.


i am not sure if it's an old kernel bug, because 
kernel-6.1.7-200.fc37.aarch64 is running on koji builds of chromium.

What “mock build” are you refering to?  Is it about the c9s buildroot?
That's only compatible with epel-next, not epel, as far as I understand

  Heya,
  
  In Fedora 20, we'll be using BlueZ 5.x to manage Bluetooth devices.
  
  Bluez5 uses a D-Bus API that's not compatible with Bluez4[1] and as
  such, management applications and a number of libraries and daemons will
  need to be ported.
  
  For GNOME 3.10 (due September 2013), Gustavo Padovan and I are going to
  be porting gnome-bluetooth, NetworkManager and PulseAudio to BlueZ5.
  Packages for BlueZ5 will be available as soon as we figure out how to
  integrate a few downstream features that were in the Fedora packages.
  
  Bluez4 and Bluez5 are not parallel-installable, and incompatible, so
  other applications relying on Bluez4 will need to be ported by their
  respective maintainers.
  
  Any analysis to what packages are affected, how many are yet to
  support the new API and how hard it will be for them to be ported
  over.
 
 I took a look to see what the impact would be. I am not a BlueZ expert,
 so Bastien, please correct me if I am wrong somewhere.
 
 BlueZ ships a daemon and provides two main interfaces for applications
 to use it:
 
  1) libbluetooth shared library
 
  2) org.bluez DBus API
 
 The TL;DL version is that in my findings, the only package that still
 needs porting to bluez 5 is blueman. Others should either just continue
 working, or need new versions packaged up.
 
 
 Applications that use the libbluetooth shared library
 -
 
 The library ABI hasn't changed and the soname in 5.x is still the same
 as was in 4.x: libbluetooth.so.3, so the impact should be minimal.
 Everything should be able to continue working without needing even a
 simple rebuild.

  For now I built without it but that means no pdf doc and no vtk support so
  I would like to fix that.
  
  
  
  Thanks for any help you might provide,
  
  
  
  With best regards,

Re: Problem with mass rebuild / latex2html errors

2013-08-05 Thread Than Ngo
we have now arm in F20 and it seems latex2html is broken on arm in F20. It's 
why 
it's built fine in F19 for you but not in f20.

why is arm plattform used by default to build noarch packages in F20?

Re: latex not working in F20: I can't find the format file `latex.fmt'!

2013-08-05 Thread Than Ngo

have you built it localy or in koji? could you please give me the url if it 
fails in koji?

which package is it?

thanks
than

 One package wouldn't rebuild because latex doesn't work.  I get the error:
 
   cd doc/res/latex  \
   latex doc.tex  \
   latex doc.tex  \
   dvips  doc.dvi -o doc.ps
   This is pdfTeX, Version 3.1415926-2.5-1.40.14 (TeX Live 2013)
restricted \write18 enabled.
 
   kpathsea: Running mktexfmt latex.fmt
   I can't find the format file `latex.fmt'!
 
 I'm BuildRequiring the following:
 
   BuildRequires:  texlive-texconfig, texlive-latex-bin-bin,
 texlive-dvips-bin BuildRequires:  texlive-metafont-bin, texlive-cm,
 texlive-ec
   BuildRequires:  texlive-preprint, texlive-cm-super, ghostscript
   BuildRequires:  texlive-pdftex-bin
 
 which works in Fedora 19, doesn't work in Fedora 20.
 
 The missing file is /var/lib/texmf/web2c/pdftex/latex.fmt, but I've no
 idea how this file gets created, nor why it doesn't get created on
 Fedora 20.  'latex.fmt' is not mentioned in any RPM script that I have
 installed on F19.
 
 Ideas where to look?
 
 And, just generally asking, WTF is going on with texlive?
 'texlive-latex-bin-bin' seriously?
 
 Rich.

Re: multilib conflict with doxygen generated pdf

2012-06-25 Thread Than Ngo
 
 This build has the pdf file with a different timestamp in the i686 and
 x86_64 build.
 
 http://koji.fedoraproject.org/koji/taskinfo?taskID=4189461
 
 The pdf file is /usr/share/doc/libbluray-devel-0.2.2/libbluray.pdf from
 libbluray-devel-0.2.2-2.fc18
 

it's a bug in pdftex (part of texlive package) which is used to create pdf 
files. pdftex writes the timestamps CreationDate (%s) and ModDate (%s) 
into PDF files.

extract from texk/web2c/pdftexdir/utils.c

---
void printcreationdate()
{
initstarttime();
pdf_printf(/CreationDate (%s)\n, start_time_str);
}

void printmoddate()
{
initstarttime();
pdf_printf(/ModDate (%s)\n, start_time_str);
}

Re: multilib conflict with doxygen generated pdf

2012-06-20 Thread Than Ngo
  I think I got this fixed in
  doxygen-1.8.1.1-2.fc18 :
  http://koji.fedoraproject.org/koji/buildinfo?buildID=325050
  
  I'll talk to than about getting a fixed build for f17 too
  
  -- rex
  
  Thanks for all the answers and thanks for the fixed doxygen. I'll try to
  build the package I have issue with for F18 asap.
 

it doesn't effect doxygen-1.8.0 in f17 and i don't plan to update new version 
in f17 yet


 So the newer doxygen doesn't help with the pdf file. I think the issue
 is the default header and footer when no LATEX_HEADER and LATEX_FOOTER
 are provided in the doxygen-config contain the timestamp. Should that be
 considered as a doxygen bug ?
 

 could you please provide a reproduce for this issue?

Thanks

Re: Screen brightness settings, are there any commands?

2011-08-05 Thread Than Ngo
you can use xgamma or xrandr to adjust gamma. 

Than

 I have problems with bug 722745
 (https://bugzilla.redhat.com/show_bug.cgi?id=722745), but I have heard
 that there are other ways to control the screen brightness settings.
 Are there any special commands you can do in addition to the gnome
 screen brightness settings? That would probably help regarding that
 bug.
