Re: [Scilab-users] scilab 6.0 beta, command line history and freezes

Hello,
I just tried  under Suse 13.2 and it seems to work as expected.

Hi everyone,

I think I found a bug (regression) in the current beta and I wonder 
whether it is related to my own setup (os, config, ...) or whether 
it's more general.
Is anyone here routinely using the current beta in command line mode 
(ie "scilab -nw" or "scilab-cli") ?
If yes, did you observe anything weird when navigating the command 
history using the up and down arrows?
For me, it freezes scilab for several minutes and does not echo the 
previous commands properly (observed on several linux 64bits 
computers), see http://bugzilla.scilab.org/show_bug.cgi?id=14535 .


Is anyone experiencing the same issue?
As anyone any clue on how to avoid it for the time being (apart from 
ripping off the up/dow arrows from my keyboard)?


Cheers,

Antoine

Re: [Scilab-users] scilab 6.0 beta, command line history and freezes

2016-04-28 Thread Pierre-Aimé Agnel 

Hi everyone,

This might be a problem with the libncurses that are packaged (that 
handles terminal display). There is a workaround for fixing it, you can 
force scilab to use your system libs with (for example)


LD_PRELOAD="/lib/x86_64-linux-gnu/libncurses.so.5" bin/scilab -nw

See if this workaround solves that problem:
=> if it solves it, I'll mark it as a duplicate of bug 14404 

=> if not you may update the bug with the result of [the following might 
be interesting if you have a scilab stuck for linux users and bug reporting]

|
gdb --pid=$(pidof scilab-bin scilab-cli-bin lt-scilab-bin 
lt-scilab-cli-bin) --eval-command='thread apply all bt'|


This will attach gdb to your stuck scilab, you can then post the back 
trace and we can analyze where the problem is.


Thank you for reporting, hope this helps,

Pierre-Aimé

The command below requires a sudo on my system:
|sudo gdb --pid=$(pidof scilab-bin scilab-cli-bin lt-scilab-bin 
lt-scilab-cli-bin) --eval-command='thread apply all bt'|


This will attach gdb to your stuck scilab, you can then post the back 
trace and we can analyze where the problem is.


Er, OK, but what are you talking about?

gdb --please-be-nice-give-me-something-called-a-backtrace?

Hi,

Basically, Yes :)
The problem with such bug is that it is quite difficult to analyze 
properly without a backtrace, and it didn't happen with most system 
configurations (besides it "froze" scilab leaving you no choice but to 
kill it without having the material to report)


Thanks a bunch for the update.
