Fixed repetitive freezing of IDE when connection drops.
when connection lost error was beeing displayed, the involved wxYield
was calling pending plc status periodic update, itself trying to use connector.
At that time connector is still not destroyed and connection
is attempted again when calling GetPLCStatus.
=> Hack : Ensure connector is destroyed before reporting error.

Better error handling when blob transfer fail

Removed dead code.

Now expects 1 more columns in VARIABLE.CSV file generated by MatIEC. Pair with MatIEC commit 9cb7c8bf7dbc :
Add a column to VARIABLES.CSV, containing variable (derived) type name, additionally to current last column contyaining base type name

Merged workaround for loading bug happening after automatic resize of function blocks. It appears that some code in GraphicCommons.py loop endlessly when wires coordinate do not align with x or y axis. Those erroneous coordinate are now filtered out when loaded in the view.

Removed debug code and closed branch

GraphicCommons.py : Wire.SetPoints() move filtering before computation of Start and End points to avoid setting them with arbitrary directions.

GraphicCommons.py : rewrote Wire.Setpoints.
- trying to make it fix diagonal wires,
- wasn't clear what was intended before, so made it clear :
- duplicate point removal
- segment merging (only if asked)
- remove corners made of opposite direction segments

'Change POU Type To' becomes 'Duplicate as...', avoiding side effects of type change when POU is already instanciated. Also remove leftover returType tag in ex-function POUs, triggering exceptions at build time.

Fix PLCObject's purge failing silently with extra_files.

LogMessage shouldn't be serialized (can lead to blocking in case of exception in main thread), and do not require it.

Fixed typo leading to some exception in some rare corner cases in worker.py

Added missing 'path' field to WAMP addresses in URI editor.

Fixed exception when using URI editor for PYRO addresses

Avoid loading PLC at startup when autostart is not set in command line. As a side effect PLC status is artificially set to Stopped, and StartPLC eventually loads PLC if it is not already loaded.

Add Repair() to WAMP interface

Merged fix_PLC_runtime_shutdown

Close fix_PLC_runtime_shutdown

Runtime worker : unblock the last waiting job and prevent any new job to wait when Main Worker is being shut down.

Add some "pipe to self" trick in Pyro server to accelerate runtime shutdown instead of waiting for arbitrary pyro timeout.

If call to GetPLCstatus can't be executed in PLC, then obtained status is disconnected. Status on "None" is not relevant anymore, and is replaced by Disconnected.

Enure that all threads are joined before trying to exit

Named runtime's threads to ease debugging

Added Repair() png icon

PEP8 fix : ./connectors/PYRO/PSK_Adapter.py:49:1: E302 expected 2 blank lines, found 1

Added RepairPLC() to PLCObject. For now just calling PurgePLC and quit PLC runtime.

Ensure Beremiz_service.py quits properly when Main Worker stops and wa are using Wx and/or Twisted.

Added PurgePLC() method to PLCObject, to be invoked when PLC Status is broken. It clears PLC shared object an extra files and force status to Empty. Added correponding Repair button to toolbar, visible only when PLC status is broken.

Background erase of debug variable panel was disabled for some reason, and it not anymore compatible with EVT_PAINT based refresh. It was leaving traces behind when removing traced variable. Fixed.

force redraw only through EVT_PAINT event and use wxPaintDC, as described in wx documentation

Fixed refresh problem following 9c5f835b031e, 9622418ac28c, c67488bd8134 : force redraw only through EVT_PAINT event and use wxPaintDC, as described in wx documentation

Continue fixing deadlock of previous commit, this time occuring when waiting for 'cleanup' python runtime call to finish. Now 'init' and 'cleanup' python runtime calls are called directly from main thread, and aren't anymore invoked in the context of wxMainloop and/or twisted reactor.

Fix deadlock when indirectly calling PLCObject's evaluator() from twisted of wx event loops. Was freezing while transfer/start/stop through Wamp. Serialize all PLCObject's call to self.PythonRuntimeCall into the same PythonThread thread.

Fixed Wamp assertion because of unexpected type

Enhanced statistics display code, used it and saw no more noticable leak while editing. Closing branch.

merged rename_on_location_change branch

Rename checkbox and immediately apply.
Added a checkbox in Location selection dialog (saved as user settings) to let user choose if variable is being renamed.
Also forced closing celle editor once new location is selected.

LocationCellEditor use better source for variable name replacement, and validate variable name before applying it or complains otherwise.

LocationCellEditor now systematically change variable name according to name given by CTN, calls VariablePanel' OnVariableNameChange to update POU accordingly.

Continued wx.NewID abuse removal in Viewer.py : get rid of one call to AppendMenu method, having no real purpose apparently. To be continued.

Start fixing wx.NewId abuse in viewer.py. This shows how to avoid using AppendMenu() function, definitely useless.

Following error was shown in Beremiz console:

Connection failed to PYROS://127.0.0.1:3001#beremiz!

Reason is that Pyro calls socket recv() with MSGWAITALL flag, that causes ValueError exception.

Merged in masterschlumpf/beremiz/generate-button (pull request #38)

"Generate Prgram" button

Approved-by: Andrey Skvortsov <andrej.skvortzov@gmail.com>

Create a "Generate Program As..." menu to make the "Generate Program" toolbutton even more useful.

The behaviour is the same as "Save" and "Save As...". Now "Generate Program" uses the last filename
if known and "Generate Progam As..." asks every time.

Add "Generate Program" to toolbar in PLCOpenEditor standalone mode.

Currently you can find the "Generate Program" action only in the file menu,
but this action is very often used in standalone mode, so I added toolbuffon.

Add SpinButtons for integer and floating point variables in ForceVariableDialog

it allows to change variable value using only mouse.

Fix non-marking as manually forced floating point variable if the value isn't integer

For example, if user in debug variable panel set any floating point
variable to 34.3, then it's not shown as forced (blue color) and user
can't release this enforcement.

If user changes the value to 34.0, then enforcement shows
correctly. This is done because binary representation of floating point
numbers in IDE and runtime can be slightly different (double vs float)
and as a result values aren't equal.

Don't close ForceVariableDialog if user entered wrong new value

return back to edit field in this case

Fix redraw problems in preview frames and debug panel

The problem was that direct call of RefreshView (now DrawView) doesn't
generate EVT_PAINT (at least on GNU/Linux with Wayland and wxgtk build

Rewrite ForceVariableDialog. It's not based on wx.TextEntryDialog

Don't customize standard wx.TextEntryDialog on the fly, implement your
own dialog for that with expected behavior and without any hacks.
