Bug#931666: sugar-toolkit-gtk3: Latest version 0.114 compatible with both Python and Python 3 is not packaged

[Aniket Mathur]

Source: sugar-toolkit-gtk3
Severity: important

Dear Maintainer,


   * What led up to the situation?
The latest version of the sugar-toolkit-gtk3 is now compatible with both
Python and Python 3, but the packages for the same are not available
, which prevents use, scaled testing and thus proper maintainance for 
the Python 3 language. 
   * What exactly did you do (or not do) that was effective (or
 ineffective)?
Have multiversion packages of the sugar-toolkit-gtk3.
   * What was the outcome of this action?
Not able to develop packages that build for both Python and Python3.
   * What outcome did you expect instead?

[Sugar-devel] Updates Regarding TelepathyGLib project

[ANIKET MATHUR]

We have completed the TelepathyGlib port of sugar, sugar-toolkit-gtk3,
collabwrapper, as well as of most of the other sugar activities.

Basic collaboration is working with TelepathyGLib.

Although there are a couple of issues with collaboration that we had
earlier with the static telepathy-python bindings as well, which are
encountered and recognised while porting.

Packaging of Sugar-toolkit-gtk3 (sugar3) v0.114

[aniket mathur]

G'day,
Aniket Mathur this side, an active contributor of Sugarlabs as well as a
GSoC 19 participant. This mail is a small query regarding the packaging of
"sugar3" module.

We currently have v0.112 packaged. In the latest version (0.114) Sugarlabs
have made the toolkit compatible with both Python and Python 3. But we
don't have Debian multi-version packages for the latest version. This
prevents us to scale our testing as well as limits the number of testers.

We don't know how to make multi-version local packages, that we can
distribute for testing.

It would be good if we have Debian packages for v 0.114.

Need Help.
Regards.
Aniket

Re: [Sugar-devel] Multiversion Packages of toolkit.

[ANIKET MATHUR]

Yes, I was asking about Debian packages. Sorry for incomplete information.

I read sources of some Debian packages:-
~ They do use six for keeping multi-version compatibility.
~ Instead of a configure.ac, they use setup.py.
~ In setup.py, they define entry-points as per the commands from the
command line specifying python-foo or python3-foo.

I also did a github search for 'python configure.ac' , looked into a
considerable amount of commits of different users and organizations with
the motive of "why don't we ask for help from those who seems to be
successful in doing it".

>From my research, I found out that the guys at "balabit" seems to be able
to do it.
I opened an issue <https://github.com/balabit/syslog-ng/issues/2814> asking
for help and clearance.

The next step is to contact the Debian developers.

Thanks!

[Sugar-devel] Multiversion Packages of toolkit.

[ANIKET MATHUR]

Hello everyone,

I have been working on developing multi-version packages for toolkit which
can build for both Python and Python 3. I successfully build packages for
python, but not able to yet built one's having multi-version support. I
have been working on this for some time in the last two weeks, trying to
get something from the source code of existing tools that have these
packages, like 'pip' and a lot more.

I need help and suggestions in this work. :-)

Could you please help me with this issue or suggestion some work around.

Re: [Sugar-devel] Problem packaging toolkit

[ANIKET MATHUR]

Thanks.
Regarding packaging for both the version, first we have to make changes in
the configure.ac file so that the toolkit is installed for both the
versions automatically?
For Python 3 do I have to make a separate repo or just push the
python3-sugar3 to the *current repo?*
Sorry, I am confused.

Re: [Sugar-devel] Problem packaging toolkit

[ANIKET MATHUR]

Thanks, made a separate github repo. Link
<https://github.com/Aniket21mathur/sugar-toolkit-gtk3-packages>.
 Regarding packaging for both Python 2 and Python 3, sorry I never came
along with same Ubuntu packages installing for both the versions of Python.
Though I have seen separate packages for Python 2 and Python 3 line pip and
pip3. I will do my research regarding this and will give updates if I found
anything useful.

Re: [Sugar-devel] Error testing collaboration using 2 Oracle virtual machines

[ANIKET MATHUR]

*Is the "Protocol 'jabber' not found on CM 'gabble'" tracebackreproducible?*
No, it is not reproducible. I get it only when I start sugar desktop for
the first time after setting sugar.

 *I don't know what you mean by "able to see the buddy icon".  In the*
*context of the thread, I'm confused.*
I meant to say that we are able to see the buddy icon of the other vm in
the neghbourhood view only if the two Vms are on the same network. So if we
are able to see the buddy icon, this means that the vm's are able to
interact, isn't it?

Thanks!

[Sugar-devel] Problem packaging toolkit

[ANIKET MATHUR]

Hello everyone.
I was trying to package sugar-toolkit-gtk3 v 0.114 following the
documentation 
.
I successfully followed till 4.2, but on running the first command in 4.3

bzr builddeb -- -us -uc

The build failed with

`
make[1]: Entering directory
'/home/aniket21/toolkit/build-area/sugar-toolkit-gtk3-0.114'
*** ach missing from po/LINGUAS ***
Makefile:859: recipe for target 'check-po' failed
make[1]: *** [check-po] Error 1
make[1]: Leaving directory

debuild: fatal error at line 1152:

`

in the terminal. Need help.

*Do you have a Collaboration Server configured in My Setting - Network?*
No, I don't have it configured, since . I am using both the vm's on the
same internal network, do I have to configure it.
Also, I am able to see the buddy icon of other instance in the
neighbourhood view of the first instance and vice versa.
Thanks!

[Sugar-devel] Problem collaborating some activities using rdesktop instances.

[ANIKET MATHUR]

To test telepathy port I made two instances of sugar using rdesktop. First
tried to collaborate using chat activity and was successful, as making the
other user friend and allowing neighborhood in the activity, gave an option
of "invite to chat activity" in the neighbourhood view.
But when I tried to do it with cookie-search or collabedit, I don't get any
such "invite to.." option. Without collaborating it's impossible for me to
test the telepathy port. Need help.
Thanks.

Thanks. Xrdp uses Xorg as default, switching to Xvnc did the job for me.
But I did one step nit mentioned in the documentation, that was
installing tightvncserver, Following the second answer in this

[Sugar-devel] Using rdesktop in Ubuntu 18.04 Vm

[ANIKET MATHUR]

I am trying to use rdesktop in Ubuntu 18.04 Vm to test port to
TelepathyGlib. I followed the steps given in the sugar-docs to set up a
sugar instance using rdesktop, but whenever I run "rdesktop -g 1200x900 -u
guest -p guest 127.0.0.1", a separate window opens, but always remains
black not showing any further activity. Am I doing Something wrong or
incomplete? Need help.Thanks.

Re: [Sugar-devel] development environment native sugar python 3 dependencies not documented

[ANIKET MATHUR]

Thanks. Used Rahul's port of telepathy for python3. Though have to make
some fixes, which I requested here
<https://github.com/pro-panda/telepathy3/pull/1>. These changes finally
resulted in a successful
python3 toolkit installed on my system so far( it might be possible that I
face problems as we proceed further ;-)). Since telepathy is quite an
essential module for the python3 toolkit to run, I propose a fork of
python3 version of toolkit to SugarLabs and mentioning of it in the
native-sugar documentation. This would help developers to set up a testing
environment until we completely port to TelepathyGlib.

I also have some questions-
-Activities like Pippy have import of jarabe module. So do we have a
python3 ported version of jarabe.  Do we need it?
- Same goes for sugargame, though for it we have a pr opened, which can be
reviewed and merged now.

Re: [Sugar-devel] [RELEASE] Sugar 0.114 stable

[ANIKET MATHUR]

Hey,
After installing the toolkit for both the python versions and running "sudo
apt install sucrose" as per the documentation

native
method,
the packages are installed for python 2 only. There is still a need to
manually install packages like decorator for python 3. So what about
telepathy?, isn't it necessary to port to TelapathyGlib to use toolkit for
python 3? Need help.
Thanks!

Re: [Sugar-devel] [RELEASE] Sugar 0.114 stable

[ANIKET MATHUR]

Hello everyone,
Even after installing the toolkit for python3 I was getting the error 'No
module named sugar3' on running "sugar-activity3 ." command. After
exploring a bit
I got to know that using the native method when I built the toolkit for
python 2 the sugar3 module is built in
'usr/local/lib/python2.7/dist-packages' and running the command "python2 -c
'import sugar3" passes. But when I install the toolkit for python3, the
module sugar3 is built in  'usr/local/lib/python3.6/site-packages' and on
running the command "sugar-activity3 ." sugar tries to read from
"usr/local/lib/python3.6/dist-packages".
 Is this a problem specific to my system(UBuntu 18.04)? A simple copy paste
of sugar3 module from site-packages to dist-packages would work?

Thank you, James.
I got a clarification from your reply. I don't think that a meeting is
required now. I will surely ask for a meeting if I am stuck anywhere. ;-)

Hello everyone,
Looking forward to have a meeting for discussing how to start with project
Port to Python 3.
It would be good to discuss, how and from where to start. ;-)

Re: [Sugar-devel] Toolkit Installation Sugar v0.113

[ANIKET MATHUR]

Thanks. James.
Agreed, there can be a number of runtime dependencies that the user has to
install. I don't think mentioning them all in the documentation
will be a good idea. What do you think?

Re: [Sugar-devel] Toolkit Installation Sugar v0.113

[ANIKET MATHUR]

hey,
I tested the changes that James made.
I started with a fresh Ubuntu 18.04 VM. Cloned artwork, datastore,
toolkit-gtk3, and sugar.
Applied his patch to toolkit-gtk3 and then followed the native procedure in
the documentation considering his changes.
I installed the toolkit for both python2 and python3.
But when I run sugar from the command line I got an import error
"import six
"ImportError:No module named six"
I am not sure why I got this error, do the dependencies and libraries used
by python3 do not get installed when the toolkit for python 3 is built?
Please help.
Thanks!

Re: [Sugar-devel] Toolkit Installation Sugar v0.113

[ANIKET MATHUR]

Regards,
I agree with, James. What I think is that since this pr
<https://github.com/sugarlabs/sugar/pull/805> is not yet merged into
master, sugar requires python 2,
and the way I was installing Sugar builds the toolkit for Python 3. So I
first installed Sugar from sucrose and then installed the toolkit-gtk3
v0.113 by hand.
Doing this I am able to test ported activities through the command line
using Ubuntu 18.04 terminal, but opening Sugar home view causes
"Segmentation fault" with a warning "python2.7 has stopped unexpectedly". I
am not yet able to figure out the reason for this.

Regarding the Python version in configure.ac, I think that the caller
should be allowed to specify the version or alternatively since we are
porting to six, a method building for both python2 and python3 would be
great.

I don't expect myself to be 100 percent right and expect to be corrected
wherever required.

Thanks a lot, everyone. ☺

[Sugar-devel] Toolkit Installation Sugar v0.113

[ANIKET MATHUR]

Greetings everyone,

I was installing Sugar v0.113 using the Native Sugar build method here
.
I was using Ubuntu 18.10. After installation, on running Sugar I received
the error message "ImportError: No module named sugar3". Need help with a
couple of questions
1) Is there a need to have a build of the older version for v0.113 to work
properly?
(never paid attention to that before).
 2) What is the correct procedure for installing v0.113?
Thanks!

[Sugar-devel] Fwd: Port to Python 3, GSoC 2019, Private Mentor Student Discussion

[aniket mathur]

Hello, Greetings
I have a couple of questions that I want to ask.
- Regarding the development environment. What is the preferred development
environment, in terms of OS and the version of Sugar or any other
compatibilities that I must have installed?
-Regarding blogs. What will be the frequency of writing blogs, and when
should we start writing those and when will the weekly meetings be
scheduled?
Looking for advice. Thanks a lot!

[Gretl-users] help | collinearity option missing under tests tab

[Rochan Mathur]

Dear Team,

I wanted to check for multicollinearity but I am unable to do so.
This is because after running the OLS regression, when I click on the
"Tests" tab, there is no option of collinearity,

I have tried the 2016 and the 2019 version of Gretl but none of it worked.

Please tell me how can I check Variance inflation Factors VIFs and check
for multicollinearity??

Re: [Sugar-devel] GSoC proposal changes

[ANIKET MATHUR]

Thanks for answering and guiding.
I am aware of the obstacles that I might face, also I am aware of the
flexibility of the timeline that might change as the work proceeds.
My timeline is just an approximate idea of how long it might take to
perform tasks in chronological order. To determine that I went through the
previous work done on each task and the work remaining to be done, to make
out approximate figures. I accept that the real difficulties are faced only
once you start working, which might entirely alter my timeline.

Also, I consider it as a possibility and accept it that I might have to
work on things not mentioned in my proposal during the program, like
porting other activities to TelepathyGlib, or other contributions to the
source code essential at that time. I know this is how things work, rather
than sticking to a timeline.

Still, I am not clear about the changes that I have to make, because there
is no such thing as a strict timeline. So do I have to keep my timeline
the same and let my mentors guide me through the work that I have to do
during the program itself?

[Sugar-devel] GSoC proposal changes

[aniket mathur]

 "your timeline has a queue of components in a set order; it is more
likely you'll need to work on all components at once; that's how it
seems to work for me."

Suggestion given by @quozl for my timeline. Should I make my timeline as a
certain percent of work done on all components together before phase
evaluations? Need suggestions. Link to my proposal.

Hi Ilnar Salimzyanov,
 Thank you so much for creating my wiki account.
Braj Bhasha (Braj Language) is a less-resourced western Indo-Aryan language
of India. There is no language resources are available for Braj Language.
But in last year some people ( Mayank Jain

worked on Braj Language to create corpus for Braj Language. As we know
there is lots of problem with less-resourced language, so there is no clear
idea about standardization of this language, but Braj language which is
spoken in Braj region taken as standard , there are few literature
(stories, poems) written in Braj Language (script used - Devanagari script)
so we take this as standard.

[Apertium-stuff] Proposal for morphological analyzer for Braj Language using the Apertium platform

[neerav mathur]

Hello Sir,

My name is Neerav Mathur. I am 4th semester post graduate student at
K.M.Institute of Hindi and Linguistics, Dr. Bhimrao Ambedkar University
Agra, Uttar Pradesh, India. I am studying Linguistics and during my
pervious semesters I have learnt Python, Machine Translation, XML. As part
of my previous semester course project, I trainer and tested MALT Parser
for Magahi Language. In order to do it, me and my classmate Mohit also
developed a small treebank for the language. In the current semester, we
are further expanding the treebank and we plan to implement the first
full-fledged parser for the language. I am also working on the development
of a machine translation system for English-Magahi language pair. As you
would notice, I am more generally interested in developing resources and
technologies for under-resourced Indian languages. As part of this, I am
interested in building a morphological analyzer for Braj Language (spoken
in Braj Region of Agra, Mathura, Alighar, Bharatpur, etc in Uttar Pradesh
and Rajasthan, India) using the Apertium platform.

I got information about GSOC and Apertium (rule-based platform for MT
and also morph analysers) during hands-on workshop on Machine Translation
by Atul Kumar Ojha, JNU. He suggested me Apertium for developing MT systems
for underresourced language and also suggested how Morphological Analyzers
help in increasing the performance of Machine translation in rule based
system, especially for morphologically rich languages. I want to work on
this project to make morphological analyzer for developing English - Braj
MT system.

I am planning to apply in Google Summer Code this year and work on this
Apertium project. Can you please suggest me if it will be a feasible plan
and if it is possible to complete this project in three months ?

Thank you !

Device Preference and FeedItemTargetService

[Varun Mathur]

Hi ,
I need to understand how to query for Device Preference from 
FeedItemTargetService in v201806 of Adwords API.

Currently (v201802), we use deviceprefernce and other non targeting fields 
in selector.Additionally we provide filters via Predicate.Before querying 
with this selector object in FeedItemService.
Now,per Migration guide (to V201806) :
All targeting fields were removed from FeedItem: devicePreference 
scheduling campaignTargeting adGroupTargeting keywordTargeting 
geoTargetingUse the FeedItemTargetService to set targeting for feed items 
instead.


Can you please help me understand how shall I still be able to query for 
devicePreference from FeedItemTargetService?

Thanks,
Varun

Re: [osg-users] Colors on GL_LINES

[Ravi Mathur]

Lighting is enabled, which is why the line darkens based on camera
position. Disable lighting on line_geometry. Search osg examples for
GL_LIGHTING to see how.

Re: [osg-users] Working with osg::Text on animation

[Ravi Mathur]

There are plenty of osg examples that show how to create your own event
handler by subclassing from GUIEventHandler. For example look at osgpoints.

Make your own event handler, and change the text visibility (using its node
mask) based on whatever keys you choose.

To update text dynamically, use an update callback attached to the Text
node. See the osgcallback example.

Re: [osg-users] Working with osg::Text on animation

[Ravi Mathur]

If you will be dynamically changing your text, then specify that when you
first create it:
osgText::Text* text = new osgText::Text;
text->setDataVariance(osg::Object::DYNAMIC);
Note that setting the data variance is important for multithreaded Viewers
.

Then you can change the text easily:
text->setText("insert dynamically-generated string here");

You can show/hide the text with its node mask:
text->setNodeMask(0x0); // NodeMask = 0 to hide
text->setNodeMask(~0x0); // NodeMask = 0x to show

Hope that helps,
Ravi

Re: [osg-users] osgText crash with multiple Viewers

[Ravi Mathur]

OK I created a small standalone program that shows the crash (attached).

To trigger the crash:

   1. Run debug version of osgmultiwindowtesttext. It will open 2 windows
   (Viewers) that contain text "Scene1" and "Scene2"
   2. Close one window -> it might crash. If it crashes, see debug info
   3. If it doesn't crash, then close the other window -> 2 new windows
   will be created -> go back to step 2

You may have to repeat step 2 many times (20 or more) before you see the
crash. The crash happens if the closed Viewer is destroyed while the open
Viewer is in the render stage for the Text.

During debug, the thread for the Viewer being destroyed will likely be in
the ~Camera() destructor. Meanwhile, the thread for the active Viewer will
be in its rendering traversal, at State::apply() for the Text's Program.
See my initial post for the codepath that ends up triggering the crash.

As I said before, I'm running on Win10, Nvidia GTX 980 (latest drivers),
Visual Studio 2013, OpenSceneGraph-3.6 branch (although it happens with
3.6.3 tag also).

I'm perfectly happy if the conclusion ends up being "don't destroy a Viewer
while another one is running". It's easy for me to pause all active Viewers
while destroying one.

Thanks,
Ravi

[tesseract-ocr] Failed to read data eng/eng.config

[anish . mathur . msbc]

I am trying to train the lstm model for my own datasets, following these 
steps TrainingTesseract-4.00 
.
While creating data set by following the step creating training data. 



I am getting the message  "Failed to read data from: 
../langdata//eng/eng.config" ,although I think I can continue the training 
part, as its a message not a error.

Anyone having an idea how to get the eng.config file ?

I am using the tesseact 4.0 on ubuntu 18.04.

Re: [osg-users] Dynamic VBO Performance Drop

[Ravi Mathur]

Thank you so much for the detailed response Wojtek! I had incorrectly
assumed that getOrCreateVertexBufferObject() "assigns" the new VBO to the
Geometry, similarly to what happens with getOrCreateStateSet() for a Node.
But after reading your response, digging into the OSG code, and reading up
more on VBOs, I understand why I was mistaken. A VBO is naturally
associated with an array so only gets created when the first array is added
to the Geometry.

After moving the setUsage code after array assignment as you suggested, I
did see a slight increase in framerate for the batched version, but not up
to par with the preallocated version. I'm using an Nvidia GTX 980 on
Windows 10. However, it does seem to be a driver issue since memory usage
settles down a bit if I leave the application running for a while after all
points have been added.

The real lesson I learned here is not to abuse OSG's automatic VBO
management by increasing the buffer in small increments at every frame. In
my actual application I run the update callback at a fixed rate and
increase the arrays by larger chunks by using resize() instead of repeated
push_back's. This seems to have fully addressed the issue.

Thanks again!
Ravi

[osg-users] Dynamic VBO Performance Drop

[Ravi Mathur]

Hello all,

I'm running into a strange performance drop issue when using dynamic VBOs
that change frequently. I am measuring performance using framerate with
vsync turned off. I know that framerate isn't always the best performance
measurement, but my example is simple enough and the performance drop is
significant and repeatable, so I feel comfortable using framerate.

The issue: Suppose I have a Geometry that will hold lots of points (e.g.
100k or more). If I choose to pre-define all points in its vertex array,
then a certain framerate is achieved. However, if I choose to add a batch
of points during each update traversal, up to the same total number of
points, then after all points have been added the framerate is much lower
than in the pre-defined model. Note that "much lower" means over 30% lower.

Note that in both cases, the same number of points are being drawn, and the
Geometry and its vertex array are created once and modified (I'm not
creating new Geometry objects at every update). All that changes is whether
I added the points all at once before rendering or a few at a time while
rendering.

I wrote a small standalone osg example (attached). Compile, run, and show
stats using:
> .\osgdynamicvbotest.exe --numPoints 10 --batchSize 10
   * If batchSize = 10 (same as numPoints) then you'll see the case
where all points are pre-defined.
   * As you reduce batchSize (e.g. 100), it will take longer to add the
total number of points, but after all points have been added and the
framerate stabilizes, you'll see it is much lower than the pre-defined case
above.

My question is, why is this happening? Is it related to intermediate VBOs
being kept in memory and slowing down the GPU? All the other forum posts I
see on the topic are either about VBOs not displaying properly (not the
case here) or about memory usage (not the case here).

Any thoughts on what's going on here would be very much appreciated.

Thank you!
Ravi

Re: [osg-users] Switch call to viewer::frame() between threads

[Ravi Mathur]

Hi Steven,

What OS are you on? On OSX, event handling MUST happen from the main
thread, so you have to coordinate the frame loop between threads.

Re: [osg-users] getWindowingSystemInterface() fails on Ubuntu 18.04

[Ravi Mathur]

Thanks guys for figuring this out. I ran into the exact same problem
earlier this week with Ubuntu 18.04. I'm using CompositeViewer similar to
the "-3" case of the osgcompositeviewer example (multiple Views in one
window). I call osg::GraphicsContext::createGraphicsContext(traits) with my
custom Traits, and of course was getting the "Unable to open display
":0.0""  error.

Robert's suggestion of calling "traits->readDISPLAY()" before creating the
graphics context seems to have fixed it.

Re: [osg-users] LookAt() function parameter meanings..

[Ravi Mathur]

Hey Martin,

You are not interpreting the parameters properly. Look at the header for
Matrixd.cpp:

  /** Set the position and orientation to be a view matrix,
* using the same convention as gluLookAt.
  */
  void makeLookAt(const Vec3d& eye,const Vec3d& center,const Vec3d& up);

It follows the same convention and algorithm as gluLookAt(), so you can
look at the many online reference pages for that (microsoft
, khronos
).
There is no question about its correctness or compatibility with OpenGL,
since OSG has been used with OpenGL in hundreds of projects for like 20
years. :D

To very directly answer your question, "eye" is the eye position (or camera
if you prefer), "center" is a point towards which the eye is looking, and
therefore the look vector points from eye towards center. This look vector
is the negative z-axis of OpenGL. The "up" vector specifies the direction
of the positive y-axis. The x-axis is then defined as y-cross-z, which is
the default OpenGL right-handed system. HOWEVER, OSG takes it a step
further and maps the y-axis to the look vector (into the screen). With this
simple rotation, x points right and z points up, which remains
right-handed. I'm guessing this is done because many OSG applications
represent physical (real-world) systems, in which the z-axis often does
point up. (Robert or someone else can correct me if that's not the reason)

Re: [osg-users] Announcement: VulkanSceneGraph and SceneGraphTestBed!

[Ravi Mathur]

I've been using Macs and developing on MacOS for over 25 years now, but
still I gotta say I completely understand your frustration Robert. My past
two computers have been Windows laptops, which is also the first time I've
bought non-Mac hardware, mainly because Apple doesn't seem to care about VR
(which has been important to me recently).

Nevertheless, supporting MacOS alongside Windows & Linux is a necessity in
my field (aerospace). It looks like Vulkan will be available on OSX, even
if it's without Apple's official support. Once VulkanSceneGraph gets going,
I'll do my bit to help with Mac support.

Requesting a TGT using a servicename

[Sushant Mathur]

Whilst using the Heimdal GSS API, I have run into a problem when calling
gss_accept_sec_context.
I do not fully understand how the digest API works, but in this case an
AS-REQ is sent to the DC with the principal as cifs/smvm1.kerb1.dom and the
response states the error:

KRB Error: KRB5KDC_ERR_C_PRINCIPAL_UNKNOWN

I added the service principal name under the user susha...@kerb1.dom but
still encountered the error. So my questions are:

1. Can a service principal name request for a TGT? If not then what method
should I use to query the DC(KDC) from another account ( most likely an
user account) from the same domain?

2. I tried doing a kinit -S cifs/smvm1.kerb1.dom susha...@kerb1.dom and did
get the ticket in the credential cache file with the principal being
cifs/smvm1.kerb1@kerb1.dom but still didn't work and heimdal still
tries to get the TGT during use.

How does the digest mode in NTLM mech for GSSAPI work exactly?

[Sushant Mathur]

I am trying to use the server side heimdal gssapi.
I am trying to specifically to get it working with NTLM.
So when I call the gss_accept_sec_context function, the following errors
are reported back by gss_display_status:

The gss major code info is :Unspecified GSS failure.  Minor code may
provide more information
The gss minor code info is :An invalid status code was supplied
The gss minor code info is :An invalid status code was supplied
The gss minor code info is :The token was a duplicate of an earlier token
The gss minor code info is :The token's validity period has expired
The gss minor code info is :An invalid status code was supplied
The gss minor code info is :An invalid status code was supplied
The gss minor code info is :An invalid status code was supplied
The gss minor code info is :An invalid status code was supplied


So I traced the code till:

_gss_ntlm_accept_sec_context -> _gss_ntlm_allocate_ctx -> kdc_alloc.

When I print the value of the krb5_context structure the error string
contained is:

Client (host/smvm1.mosmb1@mosmb1.dom) unknown

but the key table does contain this exact client name.

How do I debug farther and any other suggestions?

Predicate Pushdown not getting turned on.

[Akshat Mathur]

I created a ORC table A:

*create table A (id string i, age int, num_children int);*
*alter table A set fileformat orc;*
*insert into table A select * from B cluster by age;*

But, When I run query,
*select id from A where age=60;*

The data read from HDFS is almost equal to the size of A. I expected lesser
data due to predicate pushdown. No improvement in time also. Is there a
setting Im missing.
I run Hive 0.13 and Hadoop 2.7.0-mapr-1506.


Thanks.

I created a ORC table A:

*create table A like B;*
*alter table A set fileformat orc;*
*insert into table A select * from B sort by age;*

But, When I run query,

The data read from HDFS is almost equal to the size of A. I expected lesser
data due to predicate pushdown. Also, in reducer logs there is no mention
of ORC. I am running Hive 0.13. And size of table B was 75GB and A was 23GB.

I have used command "iw wlan0 station dump" to see set data rate as well as I 
have
sniffer. Measured data throughput is also as per 24Mbps.

Other rates are set properly except 9Mbps.By default it sets as 6Mbps, when data
transfer starts, then it set to the mentioned fixed data rate.

fixed bit rate 9Mbps set as 24Mbps in g mode(legacy)

[KAVITA MATHUR]

Hi,

I have configured AP in g mode and tested legacy rates.All basic rates and 
supported
rates(1,2,5.5,11,6,9,12,18,24,36,48,54) are set except 9Mbps.

When fixed bit rate 9Mbps is set, it gets set as 24 Mbps. This issue has been 
observed
in backports-4.4.2-1 as well as latest git version of ath10k driver.


Is anybody aware of this issue? How can I fix this rate 9Mbps?


Thanks & Regards,
Kavita

fixed bit rate 9Mbps set as 24Mbps in g mode(legacy)

[KAVITA MATHUR]

Hi,

I have configured AP in g mode and tested legacy rates.All basic rates and 
supported
rates(1,2,5.5,11,6,9,12,18,24,36,48,54) are set except 9Mbps.

When fixed bit rate 9Mbps is set, it gets set as 24 Mbps. This issue has been 
observed
in backports-4.4.2-1 as well as latest git version of ath10k driver.


Is anybody aware of this issue? How can I fix this rate 9Mbps?


Thanks & Regards,
Kavita

[packer] Reusing the state of a failed provisioned system

[tushar mathur]

Hi,

I am trying to provision my ami using a set of custom shell scripts. Sadly 
every time they fail I have to recreate an ec2 instance from scratch. This 
makes sense when I am deploying in production but at the time of debugging 
and trying out different commands it becomes really slow. 

Is there a way for me to actually reuse the state in which ec2 instance is 
currently and keep running the provisioners again and again?

I tried the --on-error argument but that only runs on the last failed step 
where as what I really want is to run the provisioning again from scratch.

packer build --debug  -on-error=ask packer-aws.json

Thanks!

My concern with creating new sessions dynamically is that, we never get 
onConnectionBound -> where we start a session on the existing connection once 
connection is established. Is there a sample or some piece of code that 
explains how to use the reactor so that we can create a new session on demand ?

Resolution: Not A Bug

As mentioned before, please use the mailing lists for questions, not the issue 
tracker.

You would add any new sessions/links in essentially the same manner as you 
added previous ones, and the event flow would be interweaved for the different 
sessions/links based on what happens on the wire.

The main concern is just that, like every other use of the reactor, youd need 
to do it on the thread running the reactor, e.g by calling the reactor wakeup 
and having an onReactorQuiesced handler somewhere able to pick up the task of 
doing the new work, or having your own timer task that picks it up, or your own 
selectable thing, etc.

Single rate issues in QCA988x based device

[KAVITA MATHUR]

Hi,

WLE600VX (2x2 MIMO, QCA9888x chipset) is used as WiFi module in my access 
point. I am
working on certification project of this system, there I need to fix single 
rate in all
the legacy, HT and VHT modes for 20MHz and 40MHz channels.

There are two problems observed during this test:

1. 9Mbps legacy rate is always set to 24Mbps in g mode. While in a mode it is 
set as
9Mbps.What can be the issue, firmware or driver? any suggestions to see this 
issue?

2. Not able to set Short GI for 40MHz channels for all the MCS except MCS 7 and 
15. What
cab be the reason for this. again, where should I suspect?..firmware or driver? 
Please
help on this.


ath10k version : git 16 oct 2017(v4.14-rc2-1-24-gc6db471)
firmware version : firmware-5.bin_10.2.4.70.66

Re: QCA988X firmware version and speed

[KAVITA MATHUR]

Hi,

I also have same observations. Rx rate is not getting updated in iw station 
dump command
with firmware version 10.2.4.70.66.Data Throughput is also degraded by 30Mbps 
with this
version.My measure throughput was 180Mbps with firmware-5.bin_25_2.1 for HT40 
mode(2x2).


Sometimes I can see 1 SS in station dump while my radio is 2x2.Is there any 
speed
difference for the FW version 10.2.4.70.66?

 Summary: How do create sessions and links dynamically once the 
connection is open ?
 Key: PROTON-1755
 URL: https://issues.apache.org/jira/browse/PROTON-1755
 Project: Qpid Proton
  Issue Type: Bug
  Components: proton-j
Affects Versions: proton-j-0.25.0
Reporter: Priyanka Mathur


Hi Proton-j folks,

We use proton-j library for establishing a connection and sending/receiving 
messages over it.Until now we never had the need to *add* a new session or new 
link to an existing and *opened* connection. Now that we have multiplexing, we 
have the need to add a new session (and)/or add a new link to already existing 
and opened connection. My question is how do I do that ? 

Once we start the reactor, we receive several callbacks and callbacks of 
importance here are

1. onConnectionInit

2. onConnectionBound -> we start a session

3. onLinkInit -> we start a link

4. onLinkRemoteOpen -> we check if link has opened

and the connection is now established.

Question is now that connection is opened,

how do I add a new session to the already opened connection ?

how do I add a new link to the already opened session ?

Is there any such support from proton-j ? As AMQP protocol clearly should 
support it.

[Paraview] Fitting ellipse to a cell

[Jairaj Mathur]

Hey Paraview community!

I have unstructured grid type data, which consists of a network of
polygons. Is there a direct way to fit an ellipse and find the properties
like major axis/minor axis?

Thanking you
