2017-01-04 Thread Yu Ning
the issue is still not reproduced on kernel 4.4. I'll try to backport
some patches that may related to dead locks:

c605f3cdff53a743f6d875b76956b239deca1272
3cd12f91514da6893954de479dc60b16d3b381f4

If they doesn't fix the issue I may have to do git bisect to locate the
fixes.

2015-05-07 Thread Yu Ning
Thanks for sudodus' reminder, I almost forgot that issue in comment
#121. Yes, current version in trusty-proposed is broken IMO, the patch
backported from trunk doesn't work in the context of trusty, so we need
to manually fix it on the installed source code (comment #124). The
tests performed by sudodus and myself are both based on this manually
modified version. What I "+1"ed in comment #143 was also for the
modified version.

BTW, about the "target and host arch" issue, it's not introduced during
the backporting to trusty. In fact you can also reproduce it on
vivid/trunk (I'm sorry I am the person who made the patch in trunk).

2015-05-06 Thread Yu Ning
@sudodus, thanks for the test.

So the new case is "burn iso for arch A on a arch B host, where A, B can
be i386 or amd64, and A != B". For this case I think there could be
several different solution:

a) do not attempt to install the target syslinux if host arch != target
arch. this will only prevent the popup error, however the generated
usbstick will still not work

b) attempt to install the target syslinux in a chroot environment. this
will work when burning an i386 image on an amd64 host, but still won't
work when burning an amd64 image on an i386 host.

c) similar to method b), but also put the qemu-ARCH-static binary in the
chroot so it will also work when burning an amd64 image on i386 host.

personally I have tested solution b) in my side (amd64, 15.04) with
below target ISO images:

* ubuntu-13.10-desktop-amd64.iso, ubuntu-14.04.2-desktop-amd64.iso, 
ubuntu-14.04.2-desktop-i386.iso, ubuntu-14.10-desktop-amd64.iso, 
ubuntu-15.04-desktop-amd64.iso: no error during burning, can boot into the 
syslinux with the usbstick successfully
* ubuntu-14.04.2-server-amd64.iso, xubuntu-14.10-desktop-amd64.iso: no error 
during burning, can't boot into the syslinux since there is no syslinux 
pre-installed in the squashfs
* debian-7.7.0-amd64-netinst.iso: no error during burning, can't boot into the 
syslinux since there is no squashfs at all

so the behavior are all as expected.

Here is my patch:

@sudodus, thanks a lot for the logs. I guess you are burning the i386
ISO on an amd64 host machine? This was a blind spot in previous patch
for vivid, it assumes host arch == target arch.

Verified on a fresh installed utopic system, the initial usb-creator
package version is 0.2.62, with this version we can reproduce the issue
by burning an trusty ISO. Then I upgrade usb-creator-common and usb-
creator-gtk to 0.2.62ubuntu0.3, I can burn the trusty ISO successfully,
and with the usbstick we can boot into the syslinux menu successfully.
So I think the issue is fixed on utopic. I'll update the tags.

2015-03-26 Thread Yu Ning
Sergio, could I know what's your host system? I attempted to reproduce
the issue with 0326 image, but the usbstick can boot into syslinux
successfully. Here is my steps:

1. download vivid amd64 0326 daily image
2. install the image
3. boot into the installed system
4. burn ubuntu trusty/vivid ISO image with usb-creator-gtk to an usbstick
5. boot with the usbstick with Legacy BIOS

To make things clear for anyone interested in this bug, let me say
something about the cause and what has been fixed and what not. Just
skip below lines if you already know :)

The cause. In the bug comments we know the root cause is that usb-
creator a) copy syslinux .c32 modules from the ISO image to usbstick,
and b) install mbr.bin from host system to usbstick. If the host system
has different version than the ISO image, then the .c32 modules will be
incompatible with the mbr.bin, for example burn an vivid ISO on an
trusty host system.

The patch. So one possible fix for the issue, is to install mbr.bin also
from the ISO image to keep it compatible with the .c32 modules. This is
what the applied patch does. However the limitation for this patch is
obvious, if there is no mbr.bin stored in the ISO then we can do
nothing. This will happen if a) no suqahsfs image in the ISO such as the
debian netinst image or b) syslinux not pre-installed in the squashfs
such as the xubuntu image.

At the moment the patch is only applied in vivid, so we have to use
latest vivid as host system to get the fix. For other host system such
as trusty we have to wait for the SRU.

2015-03-25 Thread Yu Ning
Sergio, the current patch for the issue can't fix the bug in all cases,
it requires a) the source ISO image contains a squashfs image and b)
syslinux is pre-installed in the squashfs image. So Xubuntu iso image
still can't be fixed due to b), and debian netinst iso image can't be
fixed due to a).

Please also refer to the patch for details:

Checked on vivid daily image (20150306), usb-creator version is 0.2.65.

usb-creator-gtk: a re-added image won't be automatically selected
usb-creator-kde: a re-added image will be automatically selected, and will auto

So I think we should still keep this bug open for the gtk frontend.

[Bug 1413494] Re: Free partition space isn't correctly updated after erasing

2015-02-18 Thread Yu Ning
Brian, thanks for the review, here is the declaration of unmount_all():

def unmount_all(udisks, parent):
'''Unmounts the device or any partitions of the device.'''

As you can see the last param is expected to be parent, and in my test
if we pass "dev" to it it can't unmount properly, so I think this may be
a typo of "parent_dev".

BTW, let me propose a merge request with this patch for better
reviewing.

2015-02-14 Thread Yu Ning
@Mathieu, thanks very much for the review, well, yes, I have only tested
the patch with 14.04 as host system. Actually I have two patches in
comment #83 and #84 with two different approaches:

#83: copy the *.c32 files to target, the one I proposed in the merge request
#84: install the target's mbr.bin instead of the host's one

At first I thought #84 would be the best solution since it won't install
the host files to the usbstick at all. However this was turned to be not
always work since that on some images, xubuntu for example, syslinux was
not pre-installed in the target squashfs system. That's why I finally
decide to push the #83 patch.

For the file path changing, let me check if I can get the *.c32 files by
a "find". I'll resubmit my improved patch later.

[Bug 1248720] Re: Bluetooth ON/OFF button switches OFF automatically

2015-01-27 Thread Yu Ning
The issue can also be reproduced on my 14.04, by adding some prints in
the source code I found it's cause by a logic trap:

1. we click the switch in the u-c-c bt panel to turn on the bt
2. in the widget's "notify::active" callback it set the BT state to unblocked
3. the BT "state-changed" callback is triggered with {state: unblocked, 
powered: off}, in this callback it will update the UI
4. in such a case step 2 is triggered again but this time it set the BT state 
to blocked.

So after a long repetition the final status is BT is turned off again.
Actually I'm wondering if it will run into an endless dead loop under
special condition.

Anyway in my side I could fix, or maybe only workaround, the issue with
the attached patch, it will temporarily block the widget's
"notify::active" callback in the bt killswitch callbacks, so we won't
run into step 2 after step 3.

I checked the source code and found usb-creator can only calculate the

So to fix the issue we could mount it automatically after the formating.

[Bug 1413494] [NEW] Free partition space isn't correctly updated after erasing

2015-01-21 Thread Yu Ning
Public bug reported:

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System
-> About Ubuntu

Ubuntu 14.04

2) The version of the package you are using, via 'apt-cache policy
pkgname' or by checking in Software Center

usb-creator 0.2.56.3

3) What you expected to happen

First prepare an usbstick dd'ed with zero (dd if=/dev/zero of=/dev/SDB
bs=1M count=1), then erase it with usb-creator-gtk.

After the erasing it should display the free partition space correctly,
which is usually the same value with the usbstick capacity.

4) What happened instead

After the erasing it just display the free space as an empty string "",
and we can't burn them selected source ISO in such a case.

2015-01-14 Thread Yu Ning
Hi guys, attached is a patch which will sync the *.c32 files from host
system to the target. With this patch I create a 14.10 usb stick on a
14.04 machine, and the usb stick can boot with Legacy BIOS successfully
without any error.

BTW, I wonder if we could fix this issue in a different way. Per previous 
comments we know the root cause is that the mbr on the usb stick is installed 
from the host system, which may be incompatible with the syslinux files 
included in the CD/ISO. So a possible fix is:
1. mount the CD/ISO to self.source (this is already done in current code)
2. mount the squashfs image self.source + 'casper/filesystem.squashfs' to 
self.sourcefs
3. install syslinux boot loader in the self.sourcefs chroot instead of host 
system
4. burn self.sourcefs/usr/lib/legacy/mbr.bin instead of /usr/lib/legacy/mbr.bin

Not sure if step 3 is necessary. By doing this we can make sure the mbr
and all the syslinux files are in the same version, the version used in
the source CD/ISO.

However to achieve this we have to change the dbus interface since
previously the source mount point is not passed to the InstallBootloader
dbus method. I'll make some actual test and feedback later.

reasonable way:

[Bug 1300361] Re: [SRU] cannot format when no partition table is present

2015-01-07 Thread Yu Ning
I made some tests on trusty with usb-creator-{common,gtk} 0.2.56.3.

1. create a usbstick with no partition table
2. erase it with usb-creator-gtk

I can erase it without popup error, but after the erasing it prompt
"There is not enough free space for this image." and the "Make Startup
Disk" button is inactivated. But if I erase it again now the prompt
disappears and the button is activated, and I can burn the ISO image
successfully.

So I think the issue is properly fixed. I'll update the tags for Trusty.

2015-01-07 Thread Yu Ning
I made some tests on trusty with usb-creator-{common,gtk} 0.2.56.3 in
below cases:

1. no partition table (dd if=/dev/zero of=/dev/sdb bs=1M count=1)
2. one ntfs partition
3. one ext4 partition
4. one fat32 partition
5. two ext4 partition

For case 1 & 2 & 3 & 5, after the erasing it prompt "There is not enough
free space for this image" and the "Make Startup Disk" button is
inactivated. After another erasing now the button is activated and I can
burn the ISO image successfully.

For case 5, there is also a timed out popup error, but by erasing for
the 2nd time the usbstick can be correctly erased.

Anyway since there is no TypeError popup issue reproduced, I think the
issue is properly fixed. I'll update the tags for Trusty.

Hi Phil Marsh,

Could you check the usb-creator version you are using? You can use below
command to get the package version:

apt-cache policy usb-creator-common | grep Installed

And maybe you would like to have a try on my own patched usb-creator,
you can install it with below commands:

sudo add-apt-repository ppa:yuningdodo/test
sudo apt-get update
sudo apt-get install usb-creator-gtk

I promise there is no malicious code in it, you can check my bzr branch for 
reference :)

[Bug 1208129] Re: Compares NoneType() and str(), hence fails to make bootable usb

2014-12-02 Thread Yu Ning
Thank you Jason (jasongaiser), with your debugging result I propose a
patch for the issue, it will improve the code in two points:

1. use regex to detect the os version, so 'Ubuntu Remix 14.04' is also supported
2. check whether os ver is successfully detected in need_syslinux_legacy()

however I have a concern about it, in need_syslinux_legacy() before
checking for version we should first check if it is an Ubuntu image. For
example Debian Wheezy has version string 7.7.0, which will cause
need_syslinux_legacy() to return True.

[Bug 1396464] [NEW] Audio switch between mute and unmute automatically and repeatedly

2014-11-25 Thread Yu Ning
Public bug reported:

Steps:
1. Install Ubuntu 14.04.1 image
2. launch "System Settings" -> "Sound"
3. press "Volume Down" until mute
4. press "Volume Down" for several times then press "Volume Up" immediately
5. repeat step 4 for several times

Excepted result:
everything should just works

Actual result:
system auto switch between mute and unmute automatically and repeatedly.

Once the issue is reproduced we can found cpu is running at 100% by several 
processes:
* pulseaudio
* unity-control-center
* unity-panel-service

The issue will last until we close the "Sound" window.

unity-settings-daemon version is 14.04.0+14.0420140606-0ubuntu1

2014-10-29 Thread Yu Ning
paolo, thanks a lot for the translation. Then we have the same issue, on
my box network manager is put into sleep during suspend, but not awaken
during resuming. Although the root cause is not clear yet, you can
manually execute below command as a workaround:

sudo nmcli nm sleep false

This command will manually awake network manager, so at least we don't
have to restart the computer.

hmm, if gparted doesn't work I think that is a different issue. usb-

[Bug 1361474] Re: Error erasing device when there is dos partition table but no partition

2014-10-09 Thread Yu Ning
I just updated my patch for trusty to workaround the "timed out" issue.

usb-creator uses udisks2 to format the partition table, and udisks2 uses
wipefs to erase the old partition table. However in trusty wipefs only
support erasing partitions but not partition table. So instead of
backporting the wipefs from utopic to trusty I think it's simpler to use
parted to do the job directly in usb-creator.

With this update we no longer need util-linux to be backported.

Here is the patch:

[Bug 1316734] Re: Scaling factors for high DPI screens are sometimes applied twice

2014-09-22 Thread Yu Ning
This issue is also reproduced in my 14.04 box.

In the unity-control-center I set scale factor to 1.5, before the issue
happen I checked some gsettings items:

gsettings get org.gnome.desktop.interface text-scaling-factor
1.5
gsettings get com.canonical.Unity.Interface text-scale-factor
1.0

then after several times reboot the issue is reproduced (I guess logout
and login will also trigger it), the effect is just like Martin's
screenshot. Now the two gsettings items are changed to:

gsettings get org.gnome.desktop.interface text-scaling-factor
2.25
gsettings get com.canonical.Unity.Interface text-scale-factor
1.5

I can manually restore it by below command, however the issue still will
be reproduced sooner or later.

gsettings reset com.canonical.Unity.Interface text-scale-factor

Hi, I have proposed two patches for this issue on trusty:

https://code.launchpad.net/~yuningdodo/ubuntu/trusty/usb-creator/usb-creator.lp1361474+lp1300361-recreate-udisks-client/+merge/232852
https://code.launchpad.net/~yuningdodo/ubuntu/trusty/util-linux/util-linux.backport-utopic-2.25-8ubuntu1/+merge/232848

With these two patches I can erase the usb stick successfully in below 
situations on trusty:
1. dos partition table and at least one partition
2. dos partition table without any partition
3. no partition table

For anyone who would like to give them a try, please refer to bug

JFYI, to build it dh-exec 0.13 is required, you will have to download
