SVGHMI: re-implemented tree view with classic wxTreeCtl

Non significant changes, whitespaces, etc.

SVGHMI: Added simple HMI Tree View.

SVGHMI: add a class attribute to HMI Tree nodes, set when using HMI_NODE

SVGHMI: HMI_LABEL and HMI_CLASS become HMI_NODE.
- Name of parent POU becomes HMI tree node name,
- Name of HMI_NODE variable becomes class of the node.

Add FatalError() method to ConfigTreeNode.
Extensions can report error addressed to user, without a traceback.

SVGHMI: various fixes to make SVGHMI behave on more versions of twisted and GCC.

SVGHMI - prepare page with cached data when switching. This prevents values that do not change and that was already subscribed in previous page from keeping undefined.

SVGHMI: various insignificant code moves, commenting and typos fixes.

SVGHMI : fancier second page in tests/svghmi

SVGHMI: SVG viewport now defined so that HMI take scales and fit to the view. Implemented page switch through viewport change, no hiding of widget for now.

SVGHMI - added simple Meter widget.

SVGHMI: Quicker update path for input widget when pressing on buttons, do not wait until data comes back, and simply update value text of the pressed widget. Updated PLC prog for more amimated value to display

SVGHMI: fixed HMI->PLC dataflow : not updates as expected, and not initialized properly after subscribe.

Fixed one more sequel of 5f79b194fa63 'SVGHMI: filter out temporary variables created while generating ST code out of FBD.'

SVGHMI: Added relative changes of HMI value from widgets.

SVGHMI - Fixed svghmi.{c,js} about HMI -> PLC data unpack.

SVGHMI: Added init call to all widgets at startup to bind events. More features in Input widget : Edit and Change buttons. WIP HMI->PLC value update, incoherent data detected in C part on update.

SVGHMI: dispatching data to minimalist "Display" text widget.

SVGHMI: Many fixes. Subscriptions to HMItree seems to be working, and dispatch function is called in JS with good data. Bidirectional communication now really working.

SVGHMI : many details about communication implemented in JS, with side effects.

SVGHMI: added a widgets description object, accessed by id. Added frequency to widgets, as separate template to allow future customization. Excluded non svg elements (i.e inkscape Sets) with HMI: labels from widgets.

SVGHMI fix logic for page membership detection

SVGHMI compute default page

SVGHMI: deduce pages content out of geometry (elements contained in page bounding box are in)

SVGHMI: use func:function for parsing labels so that it can be used in predicates

SVGHMI: moved/fixed some templates, avoided namespace problems, added parsing of HMI:* inkscape labels

SVGHMI: now generating JS object describing widgets and pointing to SVG elements

SVGHI: compute hmitree variables ordered index in xslt

SVGHMI: now built.

SVGHMI: Work in progress. C side mostly implemented, neither built nor tested.

SVGHMI: More strict formating of active HMI labels : @ separator only used for paths

SVGHMI: new test svg to drive next implementation

Non significant changes in generated xslt, side effect of changes in yslt_noindent.yml2

Merge default in SVGHMI branch

SVGHMI: Starting to define JS side more in details.

SVGHMI: added transformation of code given in inkscape's description fields into javascript functions

SVGHMI: gui.svg -> svghmi.svg

SVGHMI: moved static JS code to a separate file included at xhtml generation time

SVGHMI: Work In Progress : fixed pointer types in ctypes interface, cleaned up server startup and cleanup code, changed document type to XHTML, cleaner JS script : encapsulated in a function and in CDATA.

PLCobject: Call "stop" and "cleanup" methods from python runtime files in reverse order compared to "init" and "start".

SVGHMI: WIP for python<->C data exchange : message from browser hit the C side.

SVGHMI: WIP for python<->C data exchange

SVGHMI: WIP for python<->C data exchange

SVGHMI: WIP for python<->C data exchange

SVGHMI: single session for now

SVGHMI: few fixes on serving

WIP on svghmi, now builds and runs. HTTP serving + WS transport ready, missing actual data to transmit and thread to collect it.

Non significant changes to mute GCC warnings about unused variables.

Fixed sequel of 5f79b194fa63 'SVGHMI: filter out temporary variables created while generating ST code out of FBD.'. Some ref to temporary variables are still not using the _TMP_ prefix. They are quite hard to find, so to be continued...

SVGHMI: Intermediate state while working on svghmi.c

svghmi.c : deduplicated variable access code borrowed from plc_debug.c. Added targets/var_access.c.

SVGHMI: Added iterators in svghmi.c copy-pasted form plc_debug.c

SVGHMI: svghmi.c now has mutex, iterator, and read/write buffer.

SVGHMI: draft for svghmi.c. It has all PLC variables pointed in HMI tree in an array.

Pass HMITree to SVG transform. It seems it could really help to reduce JS tree binding logic in the end.

Add special nodes at HMI Tree root, fix code to handle special node (no path).

Swap CTN code gen and Libraries code gen, because SVGHMI use both, and need the library part to produce hmitree before CTN part.

yslt_noindent : Avoid YSLT's indent logic to interfere when using linequote.

SVGHMI: make a reasonably basic test

SVGHMI: filter out temporary variables created while generating ST code out of FBD.

SVGHMI: added deduction of HMI tree from list of HMI_* instances.

SVGHMI: added extraction of SVG bounding boxes, obtained from "inkscape -S", and passed to XSLT transform as variable.

Allow using docutil.get_inkscape_path() on Linux also.

SVGHMI: little fixes to make the build go through

SVGHMI: Added XSLT transformation, Makefile to get XSLT from ysl2 (copy of plcopen/Makefile) and a minimal stylesheet to start with.

Moved XSLT model query python code so that XSLT part can be reused for other transformations (i.e. in SVGHMI)

Complete SVGUI test minimal skeleton so that it builds.

intermediate commit, work in progress

Use a POU Library's Generate_C to collect all variables in SVGHMI.

merged

Enable svghmi plugin in features, and small fixes to skeleton.

Merged default in svghmi

Skeleton for svghmi extension

IDE: Allow POU Libraries to inject PLC Configurations globals during build.

WIP: initial setup.

IDE: Fixed variable traces graphs RingBuffers. Removed an apparently useless wxCallAfter in trend graph that was leading to pydeadobject exception on wxGTK when double-clicking.

IDE: Cleaned up some useless tests in variable trace data handling code, changed from bare numpy arrays to RingBuffers inorder to avoid RAM outage and crash after long tracing session.

IDE: Log: Prevent crash when display progress on empty log.

Copy description when DnD variables from CodeFile CTN to POUs

Runtime: Fix exception "Worker is disabled" when connecting while PLC runtime is starting.

Pyro/wamp/UI delegate jobs to Worker, causing race condition if worker isn't already started.
Added a function to ensure that Worker is already created when pyro or UI starts

Finished fixing Wx IDs abuse. There was still some wasted IDs because of wx.NewId calls in many places where it wasn't needed, and those IDs were not re-used. As a consequence Beremiz was making exception crashing after a few hours of intensive use.

Add ThirPartyPath call in util.path module, so that individual extensions don't have to each implement same logic to find dependencies

IDE: Add a shortcut to project "Clean" action : F9

Fixed misuse of GridCellEditor in DurationCellEditor, potentially leading to crash on windows.

Allow using spin() from ProcessLogger even with no logger given.

Runtime: Added PostStart methot to PLCObject, called after PLC is started, with all libraries and python object already created, and python extensions "Start" methods being called.
This is called before python thread processing py_eval blocks starts. Example purpose: attach additional ressource to web services

IDE: Fix logging of external process execution time so that it is visible on windows as well.

IDE: Process Logging : Add annotation in log so that user can see build is still alive and how long external process takes.

IDE: Iec2CSettings: Log wasn't available in case of exception when launching iec2c.

IDE: Log: Cosmetic changes, refactoring

IDE: Make ST code generation more verbose, since it can be really long in case of big programs, and it is better to let the user know build is still in progress.

IDE: Fixed log console that was not updating line by line smoothly when building.

Modbus plugin: map status of MB transaction onto 2 located BYTE vars (instead of a singlw WORD var).

Modbus plugin: provide user programs feedback on current connection status mapped onto a WORD located variable

Removed harmful assert in ProcessLogger.

ProcessLogger was having an assert in constructor when missing logger, leading to systematic exception when testing options accepted by compiler. This exception was silenced in ProjectController, and then MatIEC was always called without options.

Fix missing import, consequence of bad resolution of conflicting hg graft of f0a822ef9fa0 into d15a997859b1

plc_debug.c/var_acces.c : whitespace cleanup and other cosmetic changes

Prevent global python_poll blocks to be created when accidentally adding content to C-File OnChange column.

DEBUG: (IDE side) fixed wrong implementation of anti-rapid-fire leading to systematic delay in subscribing

XSLTransform.py: added get_error_log()

Attempt to workaround problem reported about empty plc.xml after unrelated crash. Now, if etree model is corrupted in a way tostring() would generate an empty string, exception prevents saving.

docsvg.py : Better error message when inkscape is not installed.

Fix unmatched "Courier" font for monospace fonts on latest ubuntu 20.04. Selected "FreeMono" instead, present since at least 18.04

Python Runtime: order of execution of extension's init() and cleanup() now reflects order of appearance of extensions in configuration tree.

Runtime: change PLCObject 'BlobAsFile' method to allow customization by overriding

WebInterface: better wording for wiping PLC content: "Repair"

runtime: added restart/reset button in web settings. Accidentaly fixed web settings logging feature.

Add a little test to see OnChange's .count .first .last in action

Fixed "Onchange" object added in previous commit

Python Safe Globals now have more reliable triggering of OnChange call. Added "Onchange" object to accessible runtime variables that let user python code see count of changes and first and last values.

Project tree: avoid flickering and glitches in notebook when selecting some still not opened ConfigTreeNode

Project tree: Clicking on ConfigTreeNode should have same behaviour as for POUS and other IEC types : simple click to select and double click to open.

py_ext: better handling of coma separated OnChange attribute for python safe global variables.

Allow customization of generated py_ext OnChange calls, by adding a static method to PythonFileCTNMixin that can the be later hot patched.

PY_EXT: OnChange is now a coma separated list of callables. Updated tests/python accordingly.

Modbus: fixed typo in ctype typing.

MODBUS: Fix saving of websettings.

Runtime/PLCObject : move call to PreStartPLC right after call to the "start" method of all python extensions, and then just before the start of the python loop executing python_* blocks.

Modbus plugin: reformat code, and add comment.

Modbus plugin: fix runtime periodic timer (don't use POSIX timer)

Modbus and Bacnet websettings : Rename variables and functions to avoid name collisions.

Websettings for modbus and bacnet are now passed to runtime as python files loaded (execfile) at init of PLCObject with the same globals.
Because if this, same names used in previously different modules now colide.

Modbus: fix strange side effect of re-use of condition variables or mutex with Xenomai : without bzero of the associated types, mutex keeps locked.

Modbus: fix client timer invalid arguments.

Modbus add a timer thread, and switch timer to SIGEV_THREAD_ID to follow xenomai posix skin restrictions.

Runtime: Fix typo in PLCObject leading to exception when reporting failure.

Py_ext: use non-derived type when generating C code for handling Python PLC globals.

tests/python : add some STRING PLC Python globals with OnChange.

Runtime: STRING type for Python PLC Globals was making problem with strings, since generated code wasn't doing comparison properly.

BACnet and Modbus : fix configuration storage directory

Runtime extrension web settings: distinguish display string and token when calling NS.newExtensionSetting, thus allowing meaningful name to be displayed instead of an id.

Debug : when BEREMIZ_DEBUG file exist, display all commands issued in console.

BACnet and Modbus : Simpler configuration management. NevowServer.py now allows each extension to create and delete multiple configuration forms in the setting page, deprecating delSettings and addAfter.

IDE: Main toolbar : Show repair button also in stop mode. Move repair button after disconnect button.

Runtime: fsync() files when transfering them, to prebent data loss when poweroff soon after programming. Fixed variable naming as a side effect.

PLCObject : reorganize code in StartPLC(), add a PreStartPLC() empty method, to be overloaded by runtime extensions.

Solve import order problem when POULibrary imports ConfigTreeNode because of UserAddressedException. Now UserAddressedException is declared in POULibrary.py, as a quick and dirty fix, but some independant module should be created for beremiz exceptions in general.

Add --on-plc-start --on-plc-stop and --status-change to runtime command line, calling given command respectively on start stop or any event. Command line string is python formated (to eventually include status with {}) before being split (supports quoted strings) and passed to Popen for non-blocking execution.

yslt_noindent : Avoid YSLT's indent logic to interfere when using linequote.

Add marker to temporary variables created while generating ST code out of FBD, so that they can be recognized as such.

Allow using docutil.get_inkscape_path() on Linux also.

Moved XSLT model query python code so that XSLT part can be reused for other transformations

Fixed unitialized parameter in instances_path stylesheet, leading to
calls to add_instance with no data when passing datatypes insteatd of project
root. That bug was making exceptions (for exemple when editing type) when
having arrays of derivated types in project.

Fixed code quality according to pep8 and pylint.

Fix exception on exit in some case, sequel of an earlier cleanup commit I couldn't find back. Disconnecting the event is apparently the way to go. https://wiki.wxpython.org/Surviving%20with%20wxEVT%20KILL%20FOCUS%20under%20Microsoft%20Windows

PurgeBlobs was faulty, but it was never having anything to purge. Fixed.

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

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

pep8 white spaces

Now default_evaluator is provided by runtime package

merge

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.

"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.

Merged search in CTN branch

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

Additional fix for rewrite ForceVariableDialog commit (9076249f)

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).

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.

Fixed Discovery panel in URI Editor dialog : double click works back again, and avoid setting URI to unicode type.

Bigger chunks, from 16k to 1M

Empirically reverted calls done just after NewPLC back to the order as it was before chunked transfer. Apparently I broke something... To be continued

Chunk based transfer for PLC binary and extra files, and some collateral code refactoring.

Fix failing PLC build when building freshly created project that use default libraries blocks. When controller loads libraries according to attibutes in project files (BeremizRoot/Enable_{libname}_Library), use known default if attribute is missing.

Cosmetic change in PSKManagement.py

Fixed ID,last URI, or last connection date not being updated when connnecting to target.

Update Beremiz translations and list of translators

Added Turkish, Romania, Portuguese, Polish, Dutch, Hungarian.
Most existed translation are updated.

Use the list of supported by app translations instead of supported translations by wx

This will make possible to translate application into locales, that
are not explicitly supported by wx: for example, 'pl' or 'bn_BD', 'bn_IN'.

Suppress message box in case current locale is unsupported or missing in wx

Beremiz can still be translated into it using own locales
available in './locale'.

Add commands to pull translation from transifex

tx - transifex cli client should be installed in the system.
It's free software and is available in Debian archive.

Run following commands:
1. Init your authorization token
$ make transifex_init

2. Pull translations
$ make transifex_pull

Add custom dialog to add/edit comment block in graphical editors

That allows to edit comment and immediately see how it'll be shown on wiresheet.

Cleanup examples so they look clean, nice and almost the same on Windows and GNU/Linux

use the same font size on Windows and GNU/Linux

use nice and pretty mono font in graphical languages (SFC, FBD, LD) as well

it looks like that was original idea, but some bug squashed in and
default font was used for POU.

at the same time fix use of mono font in the header of Variable panel
for SFC/FBD/LD POUs.

Don't need to call extra _init_

_init_ is already called for value in infos["elmt_type"]["initial"]().
Additional _init_() creates second set of child element and that
creates unusable xml project.
This regression cause by not well tested commit "Proper fix for error
'object has no attribute 'getSlave' in EtherCAT extension" (96ca6b056c55595f71bfaca9f54b9e8646460c23)

IDManager: added import/export plus little cosmetic enhancements.

IDManager : refactored a bit, moved some code into PSKManagement.py. Now captures URI and PSK on new PYRO(S) and propose them when editing URI. Import/export still to be implemented.

Renaming servicetype into scheme.

Added toolbar button to launch ID Manager dialog.

Renamed IDManager control into IDBrowser, because dialog will be named IDManager

IDManager.py : finished selector mode.

Added early implementation of IDManager.py. For now only used to select ID in URIEditor

'Merged' URI editor dialog and Discovery dialog, also clean up related code

Cut more useless code from URI Editor

URI Editor Dialog : moved it to /dialog, and fixed naming.

URI editor : Rewrote most of it, cleaner.

PSK : Stunnel and/or OpenSSL (undocumented) handles PSK better without special chars, apparently

Prevent PLCObject to be imported from IDE as a side effect of importing runtime package

WAMP : ensure that unicode string is passed for published events IDs

PYRO PSK: adjusted cipher and key length to be usable with openSSL 1.0.2k.

Automatically get PSK and ID when connecting to PYRO[S], so that future connection through PYROS can use that same key. Also fixed case to UPPER for *PSK.

Runtime : Ensure that a random PSK secret compatible with stunnel is generated if -s commandline switch is used. Stunnel service is restarted after generation, using spawn_subprocess. TODO : give stunnel restart command as a commandline parameter.

Added runtime/spawn_subprocess.py. Force use posix spawn instead of fork, with API similar to subprocess. Using fork in runtime is incompatible with Xenomai, because memory is locked and this can lead to out of memory error.

Small cosmetic change to enhance readability and avoid confusion.

Force Zeroconf to listen and answer only on interface specified with '-i' command line argument.

Useless __name__ == '__main__' tests.

Fixed PYRO's PSK_Adapter : monkey patching was breaking non-PSK protocol, and import ssl was missing.

merge

Fix PYROPSK protocol configuration. After a few iteration of trial and error it appears that TSLv1 and PSK ciphers needs to be specified

merge

PYRO/TLSPSK : must use PYROLOC* protocol scheme in pyro URI, otherwise object ID is missing. Had to use more persuasive pyro3 monkey patching to have PYROLOCPSK resolved properly

PYRO/TLSPSK : fixed typos, used appropriate ciphers (https://github.com/drbild/sslpsk/issues/3), use PYROPSK instead of unresolvable PYROLOCPSK.

Replaced PYROSSL with PYROPSK.
Secrets are files named $ID.secret in project's /psk directory.
Connect with URI formated PYROPSK://host[:port]#ID

Beremiz_service now binds both pyro and nevow ports to interface given with '-i' argument.

Fixed typo in Wampclient.py

Please pylint and pep8

Merged

Fix non-usable toolbar on wxPython with GTK3+ in PLCOpenEditor

this problem is related to 'Fix non-usable toolbar on wxPython with
GTK3+' (5927710b). This problem does not happen in Beremiz because
additional necessary self.AUIManager.Update() is called
BeremizIDE. Therefore minimal change in the mentioned commit was
enough for Beremiz, but is not enough for PLCOpenEditor.

Avoid usage of localized strings before initialization during import in many modules

This happens if import is done before i18n setup
(InstallLocalRessources()).
This affects PLCOpenEditor mostly. Beremiz IDE is free from this issue, but moving
initialization from import should make modules more robust.
Otherwise execution result depends on where and when import was done
and this is not a good thing.

Some modules (ConfigTreeNode, features, CodeFileEditor related
classes) still have this, but they are used only in Beremiz.
Most problems result in non-working internatialization.
In some cases (VariablePanel) there is backtrace, because localized
key is not found in non-localized dictionary.

Remove executable bit from source files where it's not needed.

Avoid dictionary initialization during import in PouDialog

Because initialization happened before i18n setup, then it causes later
problems during creating new POU on non-English locales (Russian for example).

Revert commit "Dirty fix for error '_object_has_no_attribute_'getSlave' in EtherCAT extension"
[a3ac46366b86a0b237dac93be6b2281ac70b98a8].

The problem was that XML elements (proxy object) in some cases were created using custom XML
classes constructors and lxml.etree.Element() call and live python
patching. This causes that lxml backend doesn't know that custom python class
should be used for these XML elements.
Proxy object can be move/deleted and recreated by lxml
backend at any point in time or this can be done in python by copy/deepcopy operations.
If this happens, then newly created
proxy elements are using default class lxml.etree._Element. And all
custom functionality is lost.

All created XML elements should be always created through corresponding
parser and class lookup callback done by lxml backend.
It's described in more details in lxml documentation:
https://lxml.de/element_classes.html

Update README for WAMP example to use crossbar with python3

crossbar python2 support is broken in v18.7.2.
I've submitted with fixes for that.
https://github.com/crossbario/crossbar/pull/1376

But they don't test crossbar with python2 in CI, so it's going to be
broken again in the future.
And there is no much reason to use crossbar with python2.

Make ID in WAMP project match with ID PLC runtime.

Fix wxHMI example after upgrading wxGlade

Newer wxGlade generates code to initialize GridSizer's with empty
elements.

...
grid_sizer_1.Add(self.window_1, 1, wx.ALIGN_CENTER, 0)
sizer_2.Add((0, 0), 0, 0, 0)

sizer_2.Add((0, 0), 0, 0, 0)

this is looks like dirty hack to fix strange problem with initial[0]
changing its type after returning from _init_ method to lxml.etree._Element
As a result all methods generated by class factory are lost.

For example, in function initMethod initial[0].__class__ points to
xmlclass.xmlclass.Config. After map(self.append, initial)
self.Config.__class__ is 'xmlclass.xmlclass.Config' as well.
But after returning from initMethod (_init) in CreateElement
self.Config.__class__ has changed to lxml.etree._Element.


I've noticed similar behavior if copy/deepcopy is used for any child
of etree.ElementBase. See simple example below.
[-------------------------------------------------------------]
#!/usr/bin/python

from __future__ import print_function
from lxml import etree
import copy

class DefaultElementClass(etree.ElementBase):
def getLocalTag(self):
return etree.QName(self.tag).localname


def printInformation(x):
print(x, x.__class__, "getLocalTag" in dir(x))


a = DefaultElementClass()
printInformation(a)

printInformation(copy.copy(a))
