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.

merge

Bacnet plugin web configuration: strip leading and trailing spaces for net. interface and port numb.

Modbus plugin, web interface: strip leading and trailing spaces from string parameters

Modbus plugin web interface: show the keyword "#ANY#" on TCP servers

Modbus plugin: fix bug: was checking user configuration against wrong limits

Modbus plugin: fix algorithm detecting Modbus TCP servers using the same IP port on the same network interface

Modbus plugin: check for duplicate "Configuration_Name"

Modbus plugin web configuration: fix comments, and delete un-used code

Modbus plugin web configuration: use drop down choices for baud, parity and stop bits.

Modbus plugin web configuration: save node type and addr type to persistant storage

Add web extension: configure Modbus Server plugin parameters

Add web extension: configure Modbus plugin parameters (currently only supports Modbus clients)

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.

merge

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.
