Fix misc typos in exception handling code.

Fixed i18n related typo.

Fixed typo

Better logging of Nevow Server import in case of exception.

WampClient : Simplified, removed dead code, use exception for handling failures and misconfiguration, check existence of mandatory parameters.

Merged #2486, enhancements to WAMP client : auto reconnecting, wamp conf checking and saving, additional attributes for exposed calls, etc

Nevow based web interface now show simple Log message sending form for basic runtime, and allow extensions to add their own web settings.

Now, runtime extensions should be able to add their own settings to web configuration interface.

Embrio of setting form, just to test

#2486 Exception if custom protocol options are wrong.

#2486 ExposedCalls with register options as a dictionary.

#2486 Renaming functions.

#2486 Reconnect funtion in SaveWampClientConf function.

#2486 Modified reconnect function. Added 'active' parameter to wampconf.json file.

#2486 Adding reconnect funtion to WampClient. Global TransportFactory not needed anymore.

#2486 Added global TransportFactory, needed in WebInterface reconnecting function.

#2486 WampClient needs pyro.plcobj before registration calls.

#2486 Fix if protocol, register options are not present in wapmconf.json file.

#2486 Added ExposedProgressCalls list using details argument for registration progress calls.

#2486 Unnecessary variable removed.

#2486 Added option to use websocket register options. Added function getValidOptins to read options from wampconf.json.

#2486 Added option to use websocket protocol options.

#2486 Updated wamp test project to work with the latest Crossbar version.

#2486 Reset delay function added. It resets the delay and the retry counter on reconnect.

BACnet : ensure that Init did happen before continuing with PLC startup.

Update list of files with strings for i18n and templates for translations

Add small contributing document with information about codestyle checking

Add argument to set list of source files to check

This is necessary, in case you want to use docker run in pretxncommit
Mercurial hook. Unfortunately for some reason if hg running in
container can't find just created commit defined by $HG_NODE. And it
throws error 'unknown revision'.

Here is example for hgrc.

[hooks]
pretxncommit.linter = hg status -m -n -a -n -I '**.py' --change $HG_NODE > files.lst && docker run --volume=$PWD:/beremiz --workdir="/beremiz" --volume=$PWD/../CanFestival-3:/CanFestival-3 --memory=1g --entrypoint=/beremiz/tests/tools/check_source.sh skvorl/beremiz-requirements --files-to-check files.lst

check_source.sh: handle case if there are no files to check

Fix linter errors

Add command line argument to run linter only on changed files

./tests/tools/check_source.sh --only-changes

It's recommended to run check_source.sh automatically on each commit,
so the rules are always enforced.
Even better is to use docker for that, so the versions of pep8 and
pylint are the same as on pipeline server.

To do this couple of lines should be added into repository's hgrc file.

[----------- cut from .hg/hgrc------------------]

[hooks]
precommit.linter = ./tests/tools/check_source.sh --only-changes
# precommit.linter = docker run -it --volume=$PWD:/beremiz --workdir="/beremiz" --volume=$PWD/../CanFestival-3:/CanFestival-3 --memory=1g --entrypoint=/beremiz/tests/tools/check_source.sh skvorl/beremiz-requirements --only-changes

Don't use fixed width labels in WAMP and PYRO dialogs

This causes problems if labels are translated into other languages and
width wasn't enough.

Fix internatialization in UriLocationEditor, PYRO dialog and Modbus configurator

Add copyright headers to retain implementation for GNU/Linux and Win32

Drop support for wxPython 2.6 and below

Autoresize UriLocationEditor dialog window

Fix compilation problem in case of TARGET_LOGGING_DISABLE turned on and TARGET_DEBUG_DISABLE turned off

Use the same retain implementation for Win32 targets

Currently plc_Win32_main_retain.c is exact copy of
plc_Linux_main_retain.c, because it's not possible to use symbol
links.

It'd be nice in the future to have possibility to modify targets.code.

Add retain basic implementation on GNU/Linux

Retain is saved in file and backup of this file is done every time.
File isn't saved on every PLC cycle to avoid high I/O load.
By default, retain is saved every second and on PLC stop/shutdown.
It's possible to override retain flush period by using CFLAGS option
in project's settings. For example, for 0.5 seconds period
use "-DFILE_RETAIN_SAVE_PERIOD_S=0.5".

Add helper function GetRetainSize()

it will be useful for retain implementations.

use CLOCK_MONOTONIC instead of CLOCK_REALTIME for timer setup

CLOCK_REALTIME is a wall clock, that could change back and forth (user
changes system time, winter/summer time, NTP corrections and so on).
For real-time application CLOCK_MONOTONIC should be used, it doesn't
have such jumps.

Add function example to first_steps example

It'll be used in documentation to show how to create function in
Beremiz.

fix type introduced by f33942053466 (fix pylint warning "(undefined-loop-variable) Using possibly undefined loop variable 'X'")

Build by default with optimization level -O2 for GCC

before -O0 was used by default, that caused pretty bad performance.

Amd64, i6700k, 4200MHz, GNU/Linux (non-RT kernel), gcc 7.2.0

-------------------------------------
Optimization | EN/ENO |no EN/ENO |
-------------------------------------
default | 11 | 9.5 |
-O3 | 3.9 | 5.2 |
-O2 | 4 | 4.8 |
-Os | 4.1 | 3.5 |
-Ofast | 3.9 | 5.2 |
-------------------------------------

ARM, BBB Cortex-A8, 600Mhz, GNU/Linux, gcc 4.6.3

-------------------------------------
Optimization | EN/ENO |no EN/ENO |
-------------------------------------
default | 273 | 226 |
-O3 | 141.8 | 106.2 |
-O2 | 142 | 107 |
-Os | 152.5 | 112.2 |
-Ofast | 141.7 | 106.2 |
-------------------------------------

For embedded systems with size constaints (like Cortex-Mx, AVR and so
on) I usually use -Os. It gets pretty good results. For
GNU/Linux-based systems -O2 is usually a good choice, as you see the
test results.

fix hangs on mouse selection in case if wxPython uses wxWidgets with GTK3+ support

This is default configuration on Debian Buster+ and Ubuntu 18.04+.
Probably it'll fix completely problem with 'clipboard already open'
described in the previous commit 5ce6d08f ("make clipboard open minimal time as wxPython documentation recommends")

make clipboard open minimal time as wxPython documentation recommends

https://wxpython.org/Phoenix/docs/html/wx.Clipboard.html#wx.Clipboard.GetData

"Call wx.Clipboard.Open to get ownership of the clipboard. If this
operation returns True, you now own the clipboard. Call
wx.Clipboard.SetData to put data on the clipboard, or
wx.Clipboard.GetData to retrieve data from the clipboard. Call
wx.Clipboard.Close to close the clipboard and relinquish ownership.
You should keep the clipboard open only momentarily."

Maybe it makes situation with pretty annoying error 'clipboard already
open' a little bit better.

PEP-8 and PyLint

PEP-8 and PyLint

Add safety check to prevent exception when disconnecting while debugging

Removed DebugThread. Take advantage of the fact that buffering is done in runtime. No need to poll for traces more than ten per second, then use simple wxTimer for that. Also removed Debug Lock since now everything happens in wx' mainloop.

Rework of runtime non-real-time threading, and shared object dynamic loading :
- All exposed operations on PLCObject are now serialized through main thread
(@RunInMain). Only one exception : python trace thread calling _GetDebugData
- Re-loading of same shared object is prevented. dlclose/delte/rewrite/dlopen
don't happen in that case. This is a workaround for some xenomai copperplate
bug triggering segfault, inbetween delete and rewrite.
- Trace thread now waits for data, dies if no data, and dies instead of
suspending as before when no data consumed after 3 seconds.
- Disabled threading in Pyro client
- Enforced auxiliary threads starting sequence : Pyro -> [UI] ->
PLCWorker.RunLoop

Stripped forgotten debug code

close branch

#2476 Fix for saving text in URI edit text box. No need to click out of URI edit text box to save edited text.

Fixed Xenomai 3 PLC stop freeze. Now use explicit finish command with pipes. Closing both ends of pipes doesn't abort blocking read anymore.

More canonical test.
There is an exception happening around here in some cases when connection is dropped while waiting for answer. Not sure that this fixes it but this is anyhow better.

PLCObject got more methods serialized through worker : Start, Stop, NewPLC.
This particularly helps with initialization/startup/re-load problems
when targeting Xenomai. It should help in general for runtime robustness,
since those operations aren't meant to be executed concurrently.

Fixed implementation of runtime worker that ensure that PLCObject Load and Unload methods always run main thread.

GetEditedElementInstancesInfos now optimized as well. Forgotten because not using [R.I.P]LibraryResolver, but still XSLT compiling was hapenning on each call.

Another attempt to make BitBuket's version of pylint happy.

Attempt to make BitBuket's version of pep8 and pylint happy.

Removed dead slow code

PEP8 and PyLint conformance: whitespaces and stuff

Copy pasted, no time wasted !

GetVariableDictionary and GetPouInterfaceReturnType optimized with new VariableInfoCollector based on XSLTModelQuery. Moved corresponding definitions out of PLCControler.py.

GetPouInstanceTagName optimized with XSLTModelQuery.

Better writing of some xpath added in previous commits about XSLT optimization.

Moved some definitions away from controller class, and adaped references them through all code.

Hook Beremiz Launcher AppStart to AdvancedSplash OnPaint event in order to ensure image is beeing displayed before loading.

Avoid endline escaping in multiline xpath epressions in xslt. '&#10;' Is apparently ignored but never know...

Fixed earlier XSLT optimizations. Some/most results were missing.

Moved some code from PLCController.py to other modules. Added necessary imports.

GetPouVariables optimized with XSLTModelQuery

Added /plcopen/InstancesPathCollector.py, to move more model xslt querying code away from PLCController.py.

Fixed Exception dialog disapearing after a view second when exception occurs during app startup.
Problem was caused by splashscreen timeout, wx closing averything else if there is no more main frame.
Changes:
- no more timeout for splashscreen
- use wx.App OnInit method to give first operation to mainloop, object are then now created in mainloop
- main loop is then created _before_ showing splash screen
- no more wxyield or wx processevent tricks needed to display splash screen
- exception handler not blocking anymore on dialog (callafter)
- because of mainloop being there before everything, exit must be called explicitely if exception caught during startup -> exit parameter in handle_exception + try/except around startup calls

UNTESTED ON WINDOWS

Moved XSLTModelQuery class to own module in plcopen package.

Added a class to speedup all XSLT queries. WIP, now only for instances_path.xslt / GetInstanceList()

Stripped useless node creation in instances_path stylesheet.

This should really help GetInstanceList to perform better: resolver removed, no more deepcopy, no more useless xml serialization, no more node-set() calls.

YSLT auto indent trick is useless here, added yslt_noindent.yml2, regenerated XSLT files

Prevent compiling XSLT on each call of GetInstanceList. To be continued. More optimization needed here. 100x would be fine...

Changed meaning of -c commandline argument for Beremiz service : only gives DEFAULT wamp config.
If existing project already has a wamp config, it is taken instead.

Factorized duplicated code

Better variable naming, and small optimization.

Unclutter graphics package scope.
Moved some import statements from "graphics" package to "viewer" module.
It also avoid systematic import of everything in graphics when we only need one submodule.

Removed dead code

Fixed pyro timeout for runtime, was set too short and runtime was disconnecting when building PLC

Ask to stop PLC before transfer if it is running

Factorized some repeated refresh code into a method, to allow customisation.

Launcher : add a debug attribute, instead of BMZ_DBG, so that customization can use it.

Stripped old dead code.

More changes in Launcher. Modules to be loaded in the background are given in a list, and assigned as object attributes. Also splitted CreateUI into CloseSplashScreen and CreatueUI.

ClassImporter now accepts string, callable or class, for compatibility with some old extensions.

Launcher: ShowUI call moves from preStart to start. ShowUI() split into CreateUI() and ShowUI(). Start()'s arguments are passed to CreateUI()
This is meant to allow customizations to pass own pre-instanciated controller to UI at startup.

Launcher: allows customizations to specify what globals passed to extensions

Documentation

Another set of meaningless changes to satisfy PEP8 and PyLint.

PEP8 conformity for modbus. Most of it done by autopep8, plus some easy refactoring.

Add some class factory function to ease declaration of simple POU libraries in customizations (i.e. TC6 XML file only, no special C code generation)

Small pep8 conformity enforcement.

Better have globals passed to python extensions (-e) than locals.

launcher : move call to ShowSplashScreen and BackgroundInitialization to PreStart()
It doesn't change behaviour of launcher in beremiz, but may have some impact on some customizations.
Some customizations need to squeeze some bitmap folder init in between app creation and ShowSplashScreen

modbus extension code cleanup, from smarteh's patch

Merged Mario's modbus branch. Fixed line endings.

merge

Ignore bug report files.

fixed erro introduced 2 commits ago (-e) : tuples have no reverse() method

Trying to get better logging/display of exceptions at runtime's startup

Changed way to deal with extensions arguments (-e) so that path and filename are stored independently and accessible for extensions themselves.

Textviewer : moved call to Colourise in a better place, so that ST highlighting gets also updated when typing in some case, not only IL

Main runtime template C code : Added HAVE_RETAIN preprocessor definition for customized build to signal it provides IEC-61131 Retain memory handling function. Removed targets/Xenomai/plc_Xenomai_noretain.c, now useless.

Clarify licensing, and packaging of runtime only files :
- moved and split targets/typemapping.py into runtime/typemapping.py and runtime/loglevels.py
- added runtime_files.list pointing to files necessary for runtime, and referring to runtime license

Enforced check_source.sh pep8 and pylint rules.

runtime/WAMP: Fixed secret loading into configuration. Fixed secret commandline switch handling.

runtime/WAMP : was 'Added time print on session left.' from dporopat. Purpose is to log (dis/re)connection, to help debugging connection problem

runtime/Wamp : adapt to unicode being enforced in latest crossbar API. Updated some documentation, to explain why there is unused definitions like SubscribedEvents or DoOnJoin.

Extend python<->PLC global variable description "GlobalDesc" to support Initial value setting.

Rebased from dporopat change "add initial value to runtime.py file", which means :
- GlobalDesc is used by some customized beremiz python runtime
- Those runtimes need to know what is initial value of these special variables

update tests/wamp README file, based on changes from dporopat.

Fixed WAMP test (crossbar confile upgrade and use same ID on both PLC and IDE side)

Fixed changes from dporopat and agregorcic about WAMP CRA and config.

WAMP runtime : changes from dporopat and agregorcic, adding CRA (-s) and changed way to load WAMP conf (-c)
- added Challenge Response Authentication,
- use -s commandline switch to give the shared secret.
- WAMP configuration now either given as -c commandline switch
or taken as default wampconf.json in project files.

Set WAMP registration option so that reconnecting while earlier session still didn't timeout is possible (in case of connection lost, for example).

More canonical overload of ReconnectingClientFactory (according twisted doc)

non significant print syntax change. ready for py3.

whitespace cosmetic for pep8

Added arbitrary timeout on Pyro, to force it to free memory after disconnect.

Moved code from to Beremiz_service.py Server class Start method to Loop method to allow customisation by hot patching. Also renamed Stop method as _stop and use Restart instead of Stop from everywhere else to make it clear that _stop actually does restart...

fix typos

comment out unused code SFC_Step.RefreshBoundingBox()

explicitly mark unused variables found by pylint with _ or dummy

pylint don't ignores unused variables with '_' in the name, even when
they are started with '_'. This bug is already fixed upstream, to fix
this in all versions of pylint custom dummy-variables-rgx is used
'_+$|(_[a-zA-Z0-9_]*[a-zA-Z0-9]+?$)|dummy'

remove unused variables found by pylint

update .PHONE target in Makefile for mki18n.py

make mki18n return 0 on success

only PyJS code is left, because it does some fancy tricks and can't be
easily fixed. So far PyJS doesn't support Python3 anyway.

remove in-tree version of Zeroconf and use upstream from
python-zeroconf package

remove reimported modules

fix unnecessary parens after keyword

enable pylint checker

so far only print statement is checked

fix usage of python2-only print statement

run python tests with non-english locale to catch bugs related to localization

make it possible to update XSD schema in project controller after new
target PLC is added or removed.

For example:


...
import targets
targets.targets["PLC"] = {"xsd": os.path.join(self.customBeremizPath, "PLCtarget", xsd),
"class": lambda: PLC_target,
"code": {"plc_PLC_main.c": os.path.join(self.customBeremizPath, "PLCtarget", "plc_PLC_main.c")}
}

from ProjectController import ProjectController, GetProjectControllerXSD
ProjectController.XSD = GetProjectControllerXSD()

fix commit "lazy initialization of highlight pens and brushes
for DebugVariableViewer" (5562f34f)

clean build example project after running test

fix problem if DataTypeEditor was imported before localization is
loaded

That doesn't affect systems with english locales.

add shell script to run all python tests and automatically handle Xvfb

add PLCOpenEditor tests

run application tests in full screen mode

clean sys.argv, because if test is running from pytest
sys.argv contains string "pytest --timeout 0 ./tests/tools"
Beremiz application parses it and throws exception.

rework Beremiz application "testCheckProject" test to allow easier reuse later

add application name for PLCOpenEditor

This is needed to work user configuration load/store, if PLCOpenEditor
is launched from test environment.

rewrite PLCOpenEditor. Add PLCOpenEditorApp class for easier customizations.

lazy locale initialization

wx.Locale() can't be called without wx.App. So don't call it at
import. It makes PLCOpenEditor simpler.

use CustomIntCtrl instead of wx.SpinCtrl because it doesn't support
long integer needed for UDINT, (U)LINT types.

This commit complements commit 74a3f4d "fix LINT and ULINT ranges".

add custom TextCtrl allowed to enter long integer with bounds checking

It's needed because wx.SpinCtrl supports only 'int' type. For UDINT
and (U)LINT long type is necessary.

use pytest for testing

run separate test on every project instead of one big long test all projects

move configuration for test environment into separate file conftest.py

lazy initialization of highlight pens and brushes for DebugVariableViewer

Constructors wx.Pen() and wx.Brush() require wx.App to exist already.
That causes crash during import of the control,
because import is done before calling main application code.

add '_' function to builtin dictionary at import time

This allows to import many Beremiz python modules before calling
util.misc.InstallLocalRessources().

remove builtin BMZ_DBG. It's not used.

update translation strings

updated all existing translations
added new languages: Portuguese (Portugal), Italian, Hungarian,
Spanish and Bengali. See version.py for information about translators.

fix LINT and ULINT ranges

found installed Inkscape on Windows

tested with Inkscape version 0.9 on Windows 7.

make possible to turn off at compile time online debugging, logging
and external sync functionality

Defines TARGET_DEBUG_DISABLE, TARGET_LOGGING_DISABLE, TARGET_EXT_SYNC_DISABLE
allow to use generated PLC code in low-cost microcontrollers,
integrate into external programs and so on.

main.c:
extern void __run(void);
int main(void)
{
for(;;) {
__run();
// sleep common_ticktime__ ns
// add common_ticktime__ ns to __CURRENT_TIME
}
return 0;
}

Compile for example for arm bare-metal:
../build$ arm-none-eabi-gcc \
-DTARGET_DEBUG_DISABLE -DTARGET_LOGGER_DISABLE
-DTARGET_EXT_SYNC_DISABLE \
-flto -ffunction-sections -fdata-sections -I../../../../matiec/lib/C \
*.c \
-nodefaultlibs --specs=nano.specs -Wl,--static -Wl,--gc-section -Wl,--start-group -lc -lm -lnosys -lgcc -Wl,--end-group

make default caption for PouNameDialog translatable

fix max value for UDINT and ULINT types

update Build icon

add couple Beremiz application tests

These tests trigger around 45% of python code.
Used in tests docker files are avaiable here:
https://bitbucket.org/skvorl/beremiz-dockerfiles

fix problem if _should_write is called by expired timer after
termination of wx application.

Initial Bitbucket Pipelines configuration

fix bug with unfinished debug thread
this bug occurs when user doesn't stop debugging process in current project, and opens another project

unify exception handling of Beremiz and PLCOpenEditor

fix problem running PLCOpenEditor

$ ./PLCOpenEditor.py
../src/common/stdpbase.cpp(62): assert "traits" failed in Get(): create wxApp before calling this

Regression was introduced by '3311eea' (clean-up: fix PEP8 E402 module level import not at top of file)

don't check any particular wx version

Beremiz works with any version of wx.

fix problem when Beremiz is running without matiec installed

set matiec settings only once on first use of ProjectController class and give
user-friendly message on compilation about missing matiec
installation.
