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.

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

Now RefreshView simply triggers EVT_PAINT and EVT_PAINT handler does actual work.

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.

Make online debug optional

It could be useful for very small targets like Atmega (Arduino) and
for target bring-up there developer want to have running PLC program,
but has not implemented runtime communication yet.


TARGET_DEBUG_AND_RETAIN_DISABLE - completely disable debug and retain
functionality. Previously named TARGET_DEBUG_DISABLE.

TARGET_ONLINE_DEBUG_DISABLE - can be used to enable retain
functionality (no define TARGET_DEBUG_AND_RETAIN_DISABLE is used), but disable
online debug with corresponding RAM/FLASH overhead.

TARGET_LOGGING_DISABLE - disables logging functionality from runtime and PLC program

TARGET_EXT_SYNC_DISABLE - disables PLC program synchronization with
external events. For example, it could be used to synchronize several
PLCs that control motors for different axes.

By default all these options are off.

To test generate program for Generic target, put following files in
project files directory and run build.sh after generating PLC program.
This is very easy to integrate into makefile (Generic target).

use pregenerated CRC32 lookup tables for retain on Win32 and GNU/Linux

This code could be possible reused on low-end targets with limited RAM.

code to generate lookup table:
[---------------------------------------------------------------------]

/* CRC lookup table and initial state. */
uint32_t crc32_table[256];

/* Generate CRC32 lookup table. */
void GenerateCRC32Table(void)
{
unsigned int i, j;
/* Use CRC-32-IEEE 802.3 polynomial 0x04C11DB7 (bit reflected). */
uint32_t poly = 0xEDB88320;

for (i = 0; i <= 0xFF; i++)
{
uint32_t c = i;
for (j = 0 ; j < 8 ; j++)
c = (c & 1) ? (c >> 1 ) ^ poly : (c >> 1);
crc32_table[i] = c;
}
}

void main(void)

Fix an exception with wx-3.0-gtk3 in PLCOpenEditor when generating ST files

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

Fix an exception on wx-3.0-gtk3 in PLCOpenEditor when generating ST files.

On Python2.7 with WX3.0 and GTK3, an assertionError rises on generating a ST file if the name is already set. The first generation works without problems, if you generate the file a second one, PLCOpenEditor tries to open the file
save dialog with the pre entered name from last run. Then the following assertion pops up:

PyAssertionError: C++ assertion "volDummy.empty() && pathDummy.empty()" failed at ./src/common/filename.cpp(568) in Assign(): the file name shouldn't contain the path

This fix reduces the filepath of the ST file the to the filename. Now it works fine.

Fix typos in function names
