[tauruslib-devel] [PATCH] Fix bug-333: compare meas. groups in lowercase

[Zbigniew R. <zre...@ce...>]

From: zreszela <zre...@ce...>

ExperimentConfiguration dict contains "MntGrpConfigs" with meas. group names
casted to lowercase (CaselessDict) but "ActiveMntGrp" may contain uppercase.
Thus cast the latter one to lowercase for proper comparison.

[tauruslib-devel] Patch for bug-333 (related to Sardana bug-498)

[Zbigniew R. <zre...@ce...>]

Hello,

I'm sending an improved solution proposed by Daniel in:
https://sourceforge.net/p/tauruslib/tickets/333/#edb1
This one is prepared for support-3.x branch. If there are no negative comments
I will apply it for both support-3.x and develop.

Cheers,

Hi, just in case someone stumbles into this who is not in the Tango List, see the very complete 
reply from Tiago in the Tango list:

Re: [tauruslib-devel] Taurus and GIL

[Carlos M. F. T. <cf...@ce...>]

Hi Giacomo,
Sorry for the late answer.
As far I know taurus does not use GIL. Taurus manages the multi 
threading in the taurusmanager class.
It class is configured by default to use concurrent threads, but it 
changes at the scheme level where the elements set it to serial instead 
by default. So, you have to explicit set the Serialization mode to 
concurrent.

e.g.

    importtaurus
    fromtaurus.core.taurusbasetypesimportTaurusSerializationMode

    a = taurus.Attribute('tango:sys/tg_test/1/short_scalar')
    a.setSerializationMode(TaurusSerializationMode.Concurrent)



For your second question, I guess you should not have problems with 
Taurus but I don't know if PyTango is affected.

Sorry for the ambiguous answer, I added the taurus list to see if 
someone else can help you.

Best,
Carlos F.

Re: [tauruslib-devel] [Sardana-users] Validate input of TaurusLabelEditRW

[Carlos M. F. T. <cf...@ce...>]

Hi Grzegorz,
The actual TaurusLabelEditRW can not allow this "feature", the method 
setValidator is there because it comes from Qt widgets.
TaurusLabelEditRW uses the TaurusLineEdit as writewidget and it 
overwrites the used validator in each event.
TaurusLineEdit creates the validator each time attending the attribute 
range, that is the reason because your solution does not work.

That I propose you is an ugly workaround :

The workaround consists in create your own TaurusLineEdit widget and 
overwrite the "_updateValidator" method.

Unfortunately these classes are not documented so I hope  this example 
can help you.

    import sys

    from taurus.external.qt import QtGui

    from taurus.qt.qtgui.application import TaurusApplication
    from taurus.qt.qtgui.input import TaurusValueLineEdit
    from taurus.qt.qtgui.compact import TaurusLabelEditRW


    class MyTaurusValueLineEdit(TaurusValueLineEdit):
         # Reimplement _updateValidator method
         def _updateValidator(self, attrinfo):
             pass


    app = TaurusApplication()

    f = TaurusLabelEditRW(writeWClass=MyTaurusValueLineEdit)
    f.model = 'sys/tg_test/1/double_scalar_w'
    validator = QtGui.QDoubleValidator(10, 20, 5)
    f.writeWidget.setValidator(validator)

    f.show()
    sys.exit(app.exec_())


The other option is somehow in your widget update dynamically the range 
of your attribute.


Could you create a ticket in taurus [1] to discuss a proper solution for 
taurus?

I reported the attribute error in a taurus ticket (but it seems to be innocuous ) for your purposes.
I attached you the taurusplot snapshot as I see.

If previously you had installed taurus3, please be sure that it was uninstalled, maybe you have a conflict with the taurus launchers.


Could you run this code and say me  if it works for you?

from taurus.qt.qtgui.plot import TaurusPlot

from taurus.qt.qtgui.application import TaurusApplication

import sys



app = TaurusApplication()



w = TaurusPlot()

w.show()

sys.exit(app.exec_())



Best,
Carlos

I was on EuroPython and there was company that want to monitor devices in factory using python, I believe that taurus and Sardana in the future might be good solution for them.
I spoke with project leader and he was interested.

Hi Łukasz,
The problem is that taurus assumes as default scheme Tango (for backward compatibilities reasons), and for  that  you see this error. The modelchooser is trying to connect to a Tango DB, to avoid it you have two options:

a) Modify in the tauruscustomsetting file the default scheme. e.g.  use Eval
b) Give a non tango model name when you call the taurus widget. e.g. eval:1

What are you trying? What scheme are you planning to use?


I hope this help you!

Carlos

Hi Lukasz,
Which version of taurus did you have installed?
Only Taurus 4 is agnostic (It is not necessary to install PyTango if you will not use tango scheme)

You can install it from repository (sourceforge ) or pypi (https://pypi.python.org/pypi/taurus/4.0.1)

git clone git://git.code.sf.net/p/tauruslib/taurus.git taurus
python taurus/setup.py install


Your 2nd snapshot is a bug that is fixed in Taurus 4, but however could be some widgets that are still being Tango-Centric.

Subject: Re: [tauruslib-devel] Taurus & data visualization from file

Hi Lukasz,

TaurusPlot is able to import data from a file:
http://www.taurus-scada.org/en/stable/users/ui/plot.html#choosing-what-is-plotted
I think that precisely CSV is not supported and the separator must be a white character and not a comma (you could try with the attached file).

One of the Taurus4 objectives was to make the development of the custom Taurus schemes more user friendly. Personally I have not written any yet, but this should be relatively easy. That means that you could write one for your file format and use Taurus widgets to visualize data from the file.

Have a nice weekend!
Zibi

Hi Łukasz,
It looks like very interesting. Let see how to solve your problems.

How did you install taurus? and from where?

I did a test installing from git and it works for me :

    git clone git://git.code.sf.net/p/tauruslib/taurus.git taurus
    cd taurus
    git checkout 4.0.1
    python setup.py install


in ipython

    In [1]: import taurus

    In [2]: taurus
    Out[2]: <module 'taurus' from
    '/usr/local/lib/python2.7/dist-packages/taurus-4.0.1-py2.7.egg/taurus/__init__.pyc'>

    In [3]: taurus.Release.version
    Out[3]: '4.0.1'



vi /usr/local/lib/python2.7/dist-packages/taurus-4.0.1-py2.7.egg/taurus/

    # Set your default scheme (if not defined, "tango" is assumed)

I reported the attribute error in a taurus ticket (but it seems to be 
innocuous ) for your purposes.
I attached you the taurusplot snapshot as I see.

If previously you had installed taurus3, please be sure that it was 
uninstalled, maybe you have a conflict with the taurus launchers.


Could you run this code and say me  if it works for you?

    fromtaurus.qt.qtgui.plotimportTaurusPlot
    fromtaurus.qt.qtgui.applicationimportTaurusApplication
    importsys

    app = TaurusApplication()

    w = TaurusPlot()
    w.show()
    sys.exit(app.exec_())




Best,
Carlos

Re: [tauruslib-devel] Taurus & data visualization from file

[Łukasz Ż. <luk...@uj...>]

Hi Carlos,

Thank you for fast reply.
I changed in the tauruscustomsetting file the default scheme from “tango” to “eval”:
[cid:image001.png@01D1E791.768BC280]
when I try to run taurusplot I get error:
[cid:image002.png@01D1E791.768BC280]

I was on EuroPython and there was company that want to monitor devices in factory using python, I believe that taurus and Sardana in the future might be good solution for them.
I spoke with project leader and he was interested.
I would like to run some demo to present taurus magic :-)

Best regards,
Lukasz

Hi Łukasz,
The problem is that taurus assumes as default scheme Tango (for backward compatibilities reasons), and for  that  you see this error. The modelchooser is trying to connect to a Tango DB, to avoid it you have two options:

a) Modify in the tauruscustomsetting file the default scheme. e.g.  use Eval
b) Give a non tango model name when you call the taurus widget. e.g. eval:1

What are you trying? What scheme are you planning to use?


I hope this help you!

Best,
Carlos

Hi Lukasz,
Which version of taurus did you have installed?
Only Taurus 4 is agnostic (It is not necessary to install PyTango if you will not use tango scheme)

You can install it from repository (sourceforge ) or pypi (https://pypi.python.org/pypi/taurus/4.0.1)

git clone git://git.code.sf.net/p/tauruslib/taurus.git taurus
python taurus/setup.py install


Your 2nd snapshot is a bug that is fixed in Taurus 4, but however could be some widgets that are still being Tango-Centric.

Carlos

Hi Carlos,

Any advice?

Hi Lukasz,
Which version of taurus did you have installed?
Only Taurus 4 is agnostic (It is not necessary to install PyTango if you will not use tango scheme)

You can install it from repository (sourceforge ) or pypi (https://pypi.python.org/pypi/taurus/4.0.1)

git clone git://git.code.sf.net/p/tauruslib/taurus.git taurus
python taurus/setup.py install


Your 2nd snapshot is a bug that is fixed in Taurus 4, but however could be some widgets that are still being Tango-Centric.


Best,
Carlos

Hi Lukasz,

TaurusPlot is able to import data from a file:
http://www.taurus-scada.org/en/stable/users/ui/plot.html#choosing-what-is-plotted
I think that precisely CSV is not supported and the separator must be a white character and not a comma (you could try with the attached file).

One of the Taurus4 objectives was to make the development of the custom Taurus schemes more user friendly. Personally I have not written any yet, but this should be relatively easy. That means that you could write one for your file format and use Taurus widgets to visualize data from the file.

Have a nice weekend!

Hello,

Best regards,

[tauruslib-devel] New releases for Jul16 (Taurus 4.0.1 and Taurus 3.7.3)

[Carlos P. <cpa...@ce...>]

Hi all,

Today we are announcing two simultaneous releases of Taurus:

- Taurus 4.0.1: the first official release for the 4.x series
- Taurus 3.7.3: a support release for the (now legacy) 3.x series

The source files and windows installers can be downloaded from PyPI:

    http://pypi.python.org/pypi/taurus


The documentation for both releases is available at:

    http://www.taurus-scada.org


Taurus 4.0.1 brings many changes. The most important are:

- Taurus core is now simpler and scheme-agnostic (tango is 
  now an optional dependency, and an scheme-agnostic API is available)
- Proper units support introduced (numerical attribute values are now 
  pint.Quantity objects)
- Model "fragments" support has been added
- The eval scheme is now much better (simpler and more powerful syntax)
- Epics scheme is now available
- taurus.qt now uses new-style PyQt signals (guiqwt3 is now supported)
- Icon resource files are no longer needed. Better Theme icon support
- Much larger and improved testsuite
- setuptools-based installer (pip now works without --egg)
- documentation has improved
- several old, deprecated and unused modules have been cleaned
- many more...

For a detailed list of changes, see the CHANGELOG:

    http://sf.net/p/tauruslib/taurus.git/ci/4.0.1/tree/CHANGELOG.md

And the issue tracker:

      http://sf.net/p/tauruslib/tickets/milestone/Jul16/

or, for a full log of commits, run (in your git repo):

      git log 3.7.0..4.0.1
      

Regarding backwards compatibility: Taurus 4.0.1 provides a backwards
compatibility API to facilitate the transition for applications created 
for taurus 3.x. Most applications should run with no or minor 
modifications in Taurus 4 and deprecation messages will be logged to 
help identifying the parts of the code that should be updated later on).
Only in very specific cases, where the compatibility cannot be handled 
automatically, the application may need to be modified in order to run 
on Taurus 4.

We encourage you to try your applications with this new release as soon 
as possible, and to report any issues found so that we can avoid a long 
transition time from 3.x to 4.x.
Please note that new features are likely to be implemented on the 4.x 
series only, and the 3.x support may be discontinued soon.


Regarding the 3.7.3 release, it is just a bugfix update with respect 
to the 3.7.0 released last January. It fixes bugs #260, #261, #269, 
#277 and #300 as well as few other issues for the 3.x series.


If you encounter problems with any of these releases, please
report them back to the taurus mailing list:

    tau...@li...

or put a ticket in the taurus project:

    http://sourceforge.net/p/tauruslib/tickets/
    

Cheers!

Carlos, (on behalf of the taurus developers)

[tauruslib-devel] [PATCH] Fix bug-319: TaurusTrend with scan "pseudo scheme"

[Zbigniew R. <zre...@ce...>]

From: zreszela <zre...@ce...>

scan is not a scheme, but a legacy implementation used by Sardana in order
to plot scan data during the scan. Treat is as a case insensitive scheme, as
Tango is.

[tauruslib-devel] [PATCH] Fix bug-315: solve "dataChanged" name conflict

[Zbigniew R. <zre...@ce...>]

From: zreszela <zre...@ce...>

TaurusModelList class defines dataChanged signal ("new style") which at the
same time overrides dataChanged slot of its base class
(QListView->QAbstractItemView).

Solve by renaming signal to dataChangedSignal at the same time maintaining
backwards compatibility (using taurus.qt.qtcore.util.signal.baseSignal utility
class).

Taurus4 is not back-comp in the connection of old-style signals.
Since Taurus 4 is not force to use PyQT API2 yet, a back-comp layer

[tauruslib-devel] TEP15: fragment-based slicing support in URIs

[Carlos P. <cpa...@ce...>]

Hi all,

I just created a draft for a new Taurus Enhancement Proposal about 
supporting slicing in taurus URIs.

Please have a look at it:

https://sourceforge.net/p/tauruslib/wiki/TEP15/

And please contribute your thoughts by replying to this thread.


Cheers,

Carlos

What do you want me to say? I do not know who cooked RFC3986, but people 
are so used to "://" following http that it seems more natural to 
specify a protocol considering the use we intend to give to the URIs:

We are not considering to use odo at this point. We were simply looking 
for a way to adapt our scripts using files as input to the use of 
particular datasets into HDF5 files. So, for the time being we'll be 
satisfied by myfile.h5::/path/to/dataset and we are looking for a way to 
specify a particular frame of a multiframe dataset. I would not be 
surprised to end up choosing something between 
myfile.h5::/path/to/dataset#10 (html like) or 
myfile.h5::/path/to/dataset::10 (odo like)

[tauruslib-devel] odo-compatible URIs (Was: Re: URIs)

[Carlos P. <cpa...@ce...>]

Hi Armando,

I hope you do not mind me posting my response to the taurus mailing list 
since I think this can be an interesting topic for discussion with all 
the developers of Taurus. See my reply below.

I did not know odo. Thanks for pointing to it. 

I will look into it later in more detail, but on a first look, it seems 
that there are no collisions with the *existing* URIs in Taurus. So it 
definitely seems a good idea to try to follow their conventions for the 
new schemes.

BUT I am worried because while in Taurus TEP3 [1] we explicitly made 
changes to enforce  RFC3986 [2], odo / PyData [3] seems not tho comply 
with it:

- odo uses "://" for specifying protocols. RFC3986 states that the 
protocol (scheme name) is separated by ":" and the "//" is actually a 
prefix for the authority part, not a separator. In practice this implies 
that if no authority is given, there must not be "//". So the "URI"
`hdfstore://myfile.h5::/data/path` is not RFC3986-compliant (I am 
assuming here that "myfile.h5" is part of the URI path, not the 
"authority").

-RFC3986 also says that authority and path *must* be separated
by "/". This means that "hostname" in `postgresql://hostname::tablename` 
is actually part of the path when it seems to me that it would make more 
sense as part of the authority.

Still, I think it might be possible to support odo to a large extent in 
taurus (and in fact, I am thinking that many new taurus schemes could be 
built upon odo itself).

But this needs to be looked at with some care.

Cheers,

Carlos

getPixmap is deprecated in favour of getCachedPixmap, but should provide
backwards compatibility for keys using resource syntax. Implement the
same solution as already present in getIcon
