Thank you for the follow up on this. This kind of problem can be very difficult
to find and debug!

Now I know the reason for the crashes. I did a lot of log writing when
creating my reports (they use OSSubprocess).
This was only for debugging. Removing them removed the problem. OSProcess
and OSSubprocess are not guilty :-)

I can crash the image with this (try several times)
(in /opt/local/bin/convert there is imagemagick):

What is class SmalltalkImageInstanceID? I have a Pharo 6.1 image, and I
am running on Ubuntu. I loaded OSProcess to check this out, but I am not
sure what that #startUp message is doing.

Re: [Pharo-dev] Pharo6 with Ubuntu and OSSubprocess/threaded heartbeat crashes and problems

2018-03-06 Thread Henrik Sperre Johansen

Seems to me aioEnable somehow triggers this.
It maintains buffers of size FD_SETSIZE (1024 on Linux)*, so an fd
parameter** >= that, could probably trigger such an error.
Maybe you could put a halt in whichever method in OSSubprocess/OSProcess
calls the primitive triggered when condition occurs, to see if that is the
cause? 
If so, identifying *why* you end up with fd's that high (which, afaik, isn't
normal), will probably lead to a workaround/solution...

Cheers,
Henry

2018-03-06 Thread Thierry Goubier

Hi Sabine,

have you tried with a 64bits version of Pharo (with a recent VM, i.e.
newer than the 6.1 vm)? I use the 5.0-201801170946, for example.

If, by chance, you manage to create a script provoking the segfault,
that may really help.

Re: [Pharo-dev] Pharo6 with Ubuntu and OSSubprocess/threaded heartbeat crashes and problems

2018-03-06 Thread Sabine Manaa

Hi,

I can report the following:

The problem with the Buffer overflow remains also with OSProcess.
Also with the normal vm (https://get.pharo.org ).

Summary: I have buffer overflow crashes with my application on Linux.
The same code runs without problems on MacOS and on Windows.
I have the same test data/database and do exactly the same.

The problem occurs only after calling several times OSProcess/OSSubprocess.
This is the reason why I first had a suspicion that OSSubprocess is
responsible for the crashes.

Can anyone tell me how to proceed to find the reason for the buffer
overflow?
There is no PharoDebug.log

Help is very appreciated!

Re: [Pharo-dev] Pharo6 with Ubuntu and OSSubprocess/threaded heartbeat crashes and problems

2018-03-05 Thread Sabine Manaa

Hi Mariano and Thierry,

I load on Pharo 32 bit with:

 spec
baseline: 'OSSubprocess'
with: [ spec
className: 'BaselineOfOSSubprocess';
repository: 'github://marianopeck/OSSubprocess:v0.2.5/repository' ];
import: 'OSSubprocess'

Tomorrow I will try to load on Pharo7 and try to use OSProcess and see if
it still crashes.

Hi Sabine,

Which OSSubprocess version are you using? If are using ConfigurationOf to
load it, then please tell me which version from there.
If you are using from baseline, tell me if you are grabbing master, a given
tag , a given commit, etc.
I will assume it is Pharo 32 bits rigth?

I will continue with a more detailed answer once you get back to me with
above questions.

Hi Alistair,

thank you! The message (pthread_setschedparam failed: Operation not
permitted)  is gone now. So Question 1 is solved.

But the crashes (Question 2) are remaining. After calling several
OSSubprocess commands, Pharo crashes without PharoDebug.log.

Anyone having an Idea what I could do?

script), we also get a crash, see [4]. Bug? wrong vm?

I am unhappy with this and it takes a lot of time. What are we doing wrong?
We want to run Pharo6 with OSSubprocess in Linux within a docker image for
our staging environment.

Help very welcome :-)

[Pharo-dev] Pharo6 with Ubuntu and OSSubprocess/threaded heartbeat crashes and problems

2018-03-05 Thread Sabine Manaa

We want to run Pharo6 with Ubuntu 16.04 Linux (in a Docker Image) and use
OSSubprocess.

For this, we use this vm: https://get.pharo.org/61+vmT

[1] tells me: "If you are installing under Linux, then you must use a
threaded heartbeat VM"

We also created a file /etc/security/limits.d/pharo.conf and put the
parameters in like described in the message [2] when startup. Also we log
out and in.

Question 1: the message (pthread_setschedparam failed: Operation not
permitted) comes again to the console each time we use OSSubprocess. As far
as I understand, it should disappear. Does this mean, that we did not edit
the pharo.conf correctly?

Question 2: after several uses of OSSubprocess within our application, Pharo
crashes (no PharoDebug.log) with the following messages [3].
How can we avoid this, what are we doing wrong?

Question 3: sometimes (!) when we load (exactly the same code loaded with a
script), we also get a crash, see [4]. Bug? wrong vm? 

I am unhappy with this and it takes a lot of time. What are we doing wrong? 
We want to run Pharo6 with OSSubprocess in Linux within a docker image for
our staging environment.

Help very welcome :-)
