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: fix bug - map BOOL flag onto C u8 (was incorrectly mapped onto u16)

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.

Merge

Modbus: more comments to remember some necessary changes.

Modbus/BACnet : add some comments so that we don't forget some pending optimization.

Modbus: Delete stored configuration when identical to default configuration.

BACnet: prevent saving configuration that is same as default, delete it if so.

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.

BACnet and Modbus: Remove additional loading and unloading, use the one already in place for extensions.

Runtime: create .md5 file at the end of all transfered files being written to disk, so that it presence indicates completeness of transfer.

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.

BACnet plugin: Add web interface for online parameter configuration

modbus_plugin: generate nicer error message, instead of a traceback

Modbus plugin: Add "exec. req. flag" and "write on change" features

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.

Etherlab : Merged 2014-2018 changes from jblee and others

Close branch ethercat_from_kosmos

EtherCat master plugin : commit changes recovered from KOSMOS 2018 installer, unkown author(s).

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

Fixed one more sequel of marking temporary variables created while generating ST code out of FBD

Changed yslt_noindent.yml2 again

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

More customizations to yslt

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

Non significant changes to mute GCC warnings about unused variables.

Fixed sequel of earlier commit in PLCGenerator.py. Some ref to temporary variables are still not using the _TMP_ prefix. They are quite hard to find, so to be continued...

variable access code moved from plc_debug.c to targets/var_access.c for easiewr re-use in ext.

Swap CTN code gen and Libraries code generation order. In general library part of an extension needs to be computed before CTN part.

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.
