Stopped at creating pool [Student seeking help] (SF#145) #91

Closed sf-migrator-bot closed 8 years ago

sf-migrator-bot commented 10 years ago

Hello! As I found no other place where to seek help regarding Sardana I'll try here.

I've installed sardana on CentOS and am facing a problem. Running Pool from command line works, but if I run Sardana or MacroServer it stops at "creating pool ..." debug message.

I'm assuming more should follow. The problem is that when running spock, everything stops after storing profile, right when spock should actually open.

Hi,

For pure questions (not bugs/feature-requests) the sardana-users mailing list is a better place. Could you please send your question there?

On a second though, I see that this can indeed be a bug report, so I write some reply here:

Please try the following:

+++++++++++++++++++++++++++++++ Open a new terminal and run:

~$ Pool demo1 --log-level=debug

(answer "Y" to question about create new instance. The last line should be something similar to: "MainThread INFO 2014-03-20 14:37:26,504 TaurusRootLogger: Ready to accept request in 0:00:00.998257")

Open another terminal and run: ~$ MacroServer demo1 --log-level=debug

(answer "Y" to question about create new instance) (copy the pool name printed above and press ENTER twice) (some log appears... the last line should be similar to: "MainThread INFO 2014-03-20 14:41:02,843 TaurusRootLogger: Ready to accept request in 0:00:08.827606")

Open another terminal and run: ~$ spock

(you should get a spock prompt) +++++++++++++++++++++++++++++++

If something does not work, pleasesend the full output from each terminal. Also send us the versions of python, tango, pytango, taurus and sardana that you are using and any info such as the way you installed them)

Note, I adapted the above instructions from: https://sourceforge.net/p/sardana/wiki/SardanaTraining-WorkshopBCN20130522/

Pool ends with "ready to accept request" MacroServer stops at "creating pool ..." (registering pool) this happens in code: http://www.sardana-controls.org/_modules/sardana/macroserver/macroserver.html

After adding some more logging print-outs, i've pinpointed the problem to the line: pool = Device(name)

Sardana - 1.3.1 Tango - 8.1.2 Python - 2.6.6 iPython - 0.10 Taurus - 3.2.0 pyTango - 8.1.1 pyQt - 4.6.2 pyQwt - Taurus reports 5.1.1, installed version is 5.2

Appending logs

Original comment by: juvanjan@SF (http://sf.net/u/juvanjan)

sf-migrator-bot commented 10 years ago

Is the pool still running on the other terminal? And, are you passing the correct pool name to the macroserver?

I notice that in your MS log, the last line says: Creating pool Pool_demo1_1 That means that you gave the door alias ('Pool_demo1_1') to the macroserver when prompted. It should be ok (in fact I tested in my case and worked ok), but I normally give the tango device name ('Pool/demo1/1') and I wonder if the problem may be there.

To check, try the following

Here is an example on how it goes on my computer. Try to reproduce it: (I will intercalate my own comments preceded by "#####")

###################################################
#### ON ONE TERMINAL:
#### Create a new Door: USE A NEW NAME!!! (e.g. demo2)
~$ Pool demo2 --log-level=debug
demo2 does not exist. Do you wish create a new one (Y/n) ? 
#### Y<ENTER>
####(...) It should get to the "accepting requests" line

###################################################
#### ON A DIFERENT TERMINAL (without closing the previous one):
~$ MacroServer demo2 --log-level=debug
demo2 does not exist. Do you wish create a new one (Y/n) ?  

#### Y<ENTER>
#### Now you should get a list of available Pools and their state:
#### Make sure that it says that Pool/demo2/1 is running

Pool_demo1_1 (a.k.a. Pool/demo1/1) 
Pool_demo2_1 (a.k.a. Pool/demo2/1) (running)

#### And now you get a prompt for introducing the Pool name.
#### Make sure to copy the pool name exactly as I write it below
#### and then hitting <ENTER> twice

Please select pool to connect to (return to finish): Pool/demo2/1  
Please select pool to connect to (return to finish):

#### (...) You may get a warning about "EventChannel": ignore it.
#### and then many INFO and DEBUG logs till we get to the following lines:

MainThread     DEBUG    2014-03-21 08:42:56,824 MS_demo2_1: Creating pool Pool/demo2/1
MainThread     DEBUG    2014-03-21 08:42:56,917 Door/demo2/1: -> init_device
MainThread     DEBUG    2014-03-21 08:42:56,919 Door/demo2/1: <- init_device
MainThread     INFO     2014-03-21 08:42:56,922 TaurusRootLogger: Ready to accept request in 0:00:24.211205

###################################################
#### Now, EVEN IF YOU STILL GOT STUCK on the Creating pool line,...
#### OPEN A THIRD TERMINAL (without closing the other two) and try:

~$ ipython
In [1]: import taurus

In [2]: pool = taurus.Device('Pool/demo2/1')

In [3]: pool.state()
Out[3]: PyTango._PyTango.DevState.ON
In [4]: ms = taurus.Device('MacroServer/demo2/1')

In [5]: ms.state()
Out[5]: PyTango._PyTango.DevState.ON

In [6]: door = taurus.Device('Door/demo2/1')

In [7]: door.state()
Out[7]: PyTango._PyTango.DevState.ON

I've followed your instructions and I get the same result as before.

Yesterday I've created a fresh copy of CentOS and am now appending exact installation process as well as interesting output from installing PyTango.

Appending both logs and Ipython output aswell.

Hi. Sorry for the long silence...

From your install_process.txt I see that you install zmq from upstream. If you installed zmq>=4, you may have hit this issue (which I just recently discovered):

https://sourceforge.net/p/tango-cs/bugs/662/

If that is the case, you could apply the already existing patch to Tango (or you could install zmq 3.2.4)

Hi Jan,

Long time has passed from your last message, so I believe you must have solved your problem. I will proceed to close this ticket. If actually you still need any help don't hesitate to reply here or drop a message to the users mailing list.

Cheers, Zibi

Hej,

I actually encountered the same problem. On Linux Sardana starts without problems with the following version numbers installed:

But on Windows (10) Sardana stops when creating the pool. Starting the Pool and the Macroserver by hand and then running Spock is also fine, but I guess it would be nice to figure out, why Sardana is not starting up correctly. I installed the following versions on the Win machine:

Best
