TBrowser( ) Crash!

[pree-jackie]

Hi Guys!
I’m new to root. Recently I’m installed root in the my PC and played with some examples. But during one tutorial (meet a Ttree) in my PC there was a crash.
I have used new TBrowser( ). TBrowser window is opened and I can able to Draw fposZ values from the tree. But there was a segmentation violation. I have attached the entire stack-trace here :

*** Break *** segmentation violation

There was a crash (#5 0x00007f271710b686 in SigHandler(ESignals) () from /home/praveen/cern_root/build/lib/libCore.so).
This is the entire stack trace of all threads:

How I can fix this issue ?
Thanks

Precisely, the crash happens when I click on the interior portion of the image. I think probably this is an issue in signal handling in Graphics system.

[eguiraud]

Hi Praveen,
I can’t see any ROOT tutorial called “meet a TTree”.
Could you provide the source code so I can try to reproduce the problem?
To save time, it would be even better if you could eliminate from the source code parts that are not relevant to the crash.

It would also help to know what version of ROOT you are running exactly and how it was installed.

Cheers,
Enrico

EDIT:
I see, it was the tutorial at this page, right?
I can inspect the tree in a TBrowser just fine, so I suspect this is a problem with your specific ROOT version/insallation. From the ROOT interpreter, what does gROOT->GetVersion() print?

[pree-jackie]

Hi @eguiraud
Yes, it is the tutorial I’m looking. My gROOT->GetVersion( ) prints “6.13/01”.
source :

TFile::Open(“http://lcg-heppkg.web.cern.ch/lcg-heppkg/ROOT/eventdata.root”);
new TBrowser()

The TBrowser window pops out, when I try to click at a point in the window the crash occurs.
I think my PC GUI is not well aligned with Root’s GUI subsystem.
I had used the commands at Root Github page to install.
$ git clone https://github.com/root-project/root.git
$ mkdir build
$ cd build
$ cmake …/root
$ make -j4
$ source bin/thisroot.sh
$ root
How i can correct this problem ? Whether I have update any GUI components in my PC or Whether a complete reinstallation can help ?
Thanks a lot for your kind help

[eguiraud]

Hi,
6.13 is an unreleased version. This means that you compiled ROOT master branch, which sometimes is unstable. Would you be able to tell me which git commit exactly you used to compile ROOT?

In any case, to normalize your situation I suggest you recompile ROOT after checking out the branch v6-12-00-patches:

cd path/to/root/source
git checkout v6-12-00-patches
cd ~
mkdir root-v612-build
cd root-v612-build
cmake path/to/root/source
make -j4
source bin/thisroot/sh

and try to use TBrowser again.

Cheers,
Enrico

[pree-jackie]

Hi !
Sorry I’m new to github terms, what do you mean by git commit ? From internet answers, I have used git describe, which prints v6-12-06-7-g4eb059c and
git log -1 which prints
commit 4eb059cbae986321d13d0b4063e68d04c7d04f0e

[TDF] Fix string search in jitting routine

I don’t know exactly what you have asked me ? Whether this is correct or not ? or what I have to do to get git commit I used to compile root.
Thanks
Praveen Velliengiri

[eguiraud]

git log shows that you brought your ROOT sources to the latest change (i.e. commit) for ROOT version 6.12 (I guess you used my git checkout command above).

You should recompile ROOT now, as indicated in my previous post. Alternatively, you can download a precompiled version from here that you can start using straight away without having to compile anything (you just need to give a source path/to/precompiled/root/bin/thisroot.sh from your commandline to make that root version active).

Also make sure that you have all the prerequisites for Ubuntu (at the end of the paragraph I linked there is an apt-get command that you can copy-paste and should install everything you need to run ROOT correctly).

If you get ROOT v6.12/06 running (either by compiling it or downloading a pre-compiled version) with all the pre-requisites installed, and you still see the crash, we need to investigate some more.

Cheers,
Enrico

Hi @eguiraud!
I have installed the 6.12 version of root in my PC. The performance of TBrowser is comparatively better in 6.12 than 6.13. But the response time of TBrowser window is very high, which is bad. And I can’t able to close the TBrowser window and even I can’t able to type anything in the terminal when the window is open. It also produce different errors.
It takes too long to interact with window and use it effectively. I think there is an issue in graphics subsystem. Whether the graphics subsystem is working properly on all supported platforms ? I have attached a long error message list also below

@eguiraud
Could please you point me to some example code which uses graphics subsystem, so that we can able to dig deeper to find whether it is issue or my system bug.
Thanks

Hi,
all of this is quite weird.

Let’s try to break it down:

1. TBrowser feels sluggish: if you just open the root prompt and type TBrowser b a TBrowser should open. Is that TBrowser, with no ROOT files attached, slow at responding to clicks? About how long does it take from when you click on the File menu entry to when the drop down menu appears?

2. Errors at the console: what is the minimum required set of actions that I can perform to reproduce the issue? Can you reproduce the issue on a different computer?

You can type .demo at the ROOT prompt to get a window that lets you plot a few simple graphs with a click.
Otherwise you can test the examples under $ROOTSYS/tutorials/{graphics,graphs,gui,hist,etc...}

@eguiraud
The TBrowser object is associated with a root file (TTree, with fposX, fposY, fposZ, fmomentum, datas ). It usually takes some 15 seconds to respond. When I try to plot further like fposX, fposY the waiting time exceeds 15 seconds

[eguiraud]

What about my questions above?

If TBrowser is only slow in drawing histograms on canvas, that might be because it takes a long time to process your file, for whatever reason.

@eguiraud
Errors at the console:
I did

TFile::Open("http://lcg-heppkg.web.cern.ch/lcg-heppkg/ROOT/eventdata.root");

new TBrowser( )

I takes 10 seconds to load the entires from the file, and takes some 10 seconds to produce the plots. When I close the window sometimes the crash happens.

But I think it’s just a simple file. I have heard that physics collision data is usually in GB’s. How can the TBrowser process it ?
