IDE: Optimization of modification events processing in text editors.

Too many modifications types where registered, and then too many events were fired.
Also, in case of uninterrupted sequence of events, updates to the model is deferred to the end of that sequence (wx.Callafter).

SVGHMI: cosmetic change

SVGHMI: do not try to reconnect websocket if closed properly by server.

Tests: force bigger fonts and flat theme in GTK to make OCR more reliable.

OPC-UA: tolerate better pre-encryption formated client configuration file.

OPC-UA: only support the encryption policy selected in config.

By default open62541 client accepts all supported policies, but in makes problem
when negociating with some servers while most clients seems to only support
one policy at a time.

Tests: add encrypted OPCUA browsing test.

Tests: IDE: add stdout monitoring capabilities to auxiliary process

OPC-UA: Update CTN "ChangesToSave" status when variable selection change.

- fixes changes not being saved when no other changes happening to configuration
- added CTNMarkModified to ConfigTreeNode in order to generalize

Tests: Add project for OPC-UA server browsing and variable picking UI test

Tests: Add OPC-UA server browsing and veriable picking UI test.

Tests: Add 'dragNdrop' for UI tests with slower begining than sikuli's dragDrop

Tests: UI tests now avoid polling stdout if process didn't start.

Tests: UI tests can now load projects from tests/projects

Tests: add command for UI tests to launch and close Auxiliary Process

OPC-UA: better handling and reporting of server browser's connection errors.

OPC-UA: Extend Drag'N'Drop target to whole input or output panel not only grid.

Merge default in wxPython4

SVGHMI: fix HMI freeze at load when no screen saver is defined

SVGHMI: update generated XSLT

SVGHMI: watchdog now calls OnStart and OnStop commands just after calling OnWatchdog. Therefore, OnWatchdog command should not restart browser by itself.

SVGHMI: server systematically resets session on connect, rather than waiting for client to ask for it

IDE: Fix DropTarget() methods that must return a bool with wxPython4.

IDE: Fix visibility of text in Debug panel when using dark theme.

IDE: Fix use of deprecated wx.NamedColour

Merged changes from default in wxPython4 branch

SVGHMI: update generated XSLT

SVGHMI: use messy test/projects/svghmi to give a try to ScreenSaver feature.

Backed out changeset c6068b674b30

SVGHMI: update generated XSLT

SVGHMI: enable periodical reconnect when browser is QtWebengine, working around memory leak with websocket on Qt's embedded Chromium.

IDE: Added filtering in POU instance variables panel.

SVGHMI: add automatic reconnection of websocket with 1s reconnection delay after first attempt.

SVGHMI: prevent browser and watchdog commands to become zombie once finished.

test fails if project_files is missing.

OPC-UA: better logging in case of failure at init

Tests: version bump open62541 v1.3.2 -> v1.3.3 for github CI workflow.

Tests: add opc-ua encrypted test

Merged changes from default

SVGHMI: update generated XSLT

SVGHMI: Update svghmi_references example to demonstrate use of Assign widget.

SVGHMI: Add Assign widget, doing multiple assignments on click.

SVGHMI: add visible feedback to Jump widget when clicked/touched

SVGHMI: add support for "reference" and "frame" rectangles to spread-out ovelapping elements.

When HMI become complicated, designer needs to spread-out ovelapping elements
in order to unclutter drawing and facilitate maintenance.

SVGHMI: remove intermediate "updates" Map and apply_updates()

It was used initially to decouple DOM updates from reception of data through
websocket, but now since all widget SHOULD use animate() to modify DOM, and
dispatch() only change internal state, apply_update is unnecessary.

SVGHMI: cosmetic fix in js

SVGHMI: do not discard out-of-page elements inside widgets that are ovelapping pages.

SVGHMI: update generated XSLT

OPCUA: cosmetic fixes

CLI: poll runtime log and output new entries to stdout.

CLI: when using --keep, do not disconnect before being interrupted

Runtime: work around 1s delay added when using twisted reactor's callLater.

Since wxPython4, using wxReactor from non-main thread was producing
exceptions in wxWidget's C++ code. Then reactor.run() was called from
main thread, and runtime's worker was delegating calls to reactor
with callLater(0, callable).

While this worked perfectly with wxReactor, it did introduce an unexplained
1 second delay to each worker call when using nomal linux reactors
(i.e. without wxPython). As a workaround reactor runs in a thread when using
twisted without wxPython

tests: opcua_client test project is not meant to be encrypted.

SVGHMI: update generated XSLT files

Merged changes from default

SVGHMI: ensures that PLC sends only fresh data to HMI, even right after variable being subscribed.

OPC-UA: add logging to help user to understang what went wrong when connecting.

OPC-UA: fix LDFLAG, missing OpenSSL's -lcrypto

open62541 is linked staticaly, therefore shared object dependencies have to be given explicitely.

tests: missing SSL support in open62541 build parameters

SVGHMI: Add predefined assignments to jump widget to notify PLC or other widgets about jump.

SVGHMI: continue rework of Jump widget to cope with Enable Expressions.

Questioning widget's activity and disability all together.
Now active/inactive/disable masquarade is all managed in widgets_common.
Propagated changes to widget already using activity (buttons)

SVGHMI: rework Jump widget to cope with Enable Expressions.

Relative jumps are not disabled implicitely anymore when pointed HMI_NODE is 0.
Also, "activable()" implementation was enhanced to make it optional.

SVGHMI: add support for "enable expressions" with arbitrary variable name assignment.

HMI tree paths can be prefixed with a variable name "@name=/MY/HMI/VAR"
Widget declarations can end with a "#" followed by a JS expression that refers to name given to variables.
Widget is disabled if expression's result is false.

Commit includes some more-or-less related generated code refactoring, that should simplify extending widget's variables attributes.

SVGHMI: preliminary implementation of a general enable bit for all widgets, using "#" at the end of widget declaration, and a "disabled" element that becomes visible instead of widget when disabled.

SVGHMI: rename veriables in parse_labels.ysl2 for better readability

OPC-US client: add support for x509 and user+password authentication.

Commit for backup not including tests since encrypted OPC-UA test are still not valid.

icon right-click menu.

Probably a consequence of wxPython upgrade, together with initial bad idea to
move wx.app.mainloop in non-main thread.

Remove useless assignment

SVGHMI: update generated XSLT

tests: fix load_and_build_tests.pytest

Leftover import from previously commented-out tests. Commented out as well.

Merge changes from default in wxPython4

After an empty line, the rest of the description field is left for description text.

Runtime: Fix PLC python thread crash in case of exception in PostStart customization hook.

IDE+Runtime: fix exception when reconnecting with non-empty trace/force list.

Sometimes, remote call to SetTraceVariableList returned None just after reconnecting:
- changed caller to accept None (in case of connection problem)
- changer SetTraceVariable list to return 4 (DEBUG_SUSPENDED) if debug is suspended

Runtime: Retain: fix missuse of static classifier leading to ever increasing offset.

IDE: one more consequence of wxPython's 3 to 4 version bump

IDE+runtime: Fix .ico generation

SVGHMI: fix Switch widget so that order of choices elements is preserved across detaching and re-attaching.

SVGHMI: update generated xslt files

SVGHMI: nasty scope shadowing bug... was making funny recursion, leading to really slow interaction.

SVGHMI: fading page switch : to avoid blinking, page stays black once fading finished and next page is still not ready.

SVGHMI: fading page switch : defer update of classList to next animate() call when finishing transition.

classList update was happening in the same call as switch_page(), but this call is not meant to do any change in the DOM. This was triggering unwanted style and layout recomputation.

SVGHMI: rework Switch widget : detach/attach elements instead of hiding with style.display, detach all possible choices at init.

SVGHMI: add fading transition to make page switch feel more responsive on slow machines.

SVGHMI: add a way for widgets and other yslt2 files to add css definitions to resultng page.

Tests: No need to archive test results before uploading them as action artifacts.

Tests: ...

Tests: re-enable running test in github action, now that docker image should be cached.

Tests: temporary disable problematic part, to force action to succeed so caching can happen.

Tests: give test directory when creating container, not when running test.

Tests: fix docker image export for GitHub Action caching.

Tests: More fixes amd enhancments to run tests on Github Actions

Tests: use script rather than alias so that bash doesn't need to be interactive shell with a TTY

Tests: remove -it from docker invocation

Workaround "The input device is not a TTY" error on Github Action.

Create run_tests_in_docker.yml

SVGHMI: Add support for forcing widget update frequency with period longer than a second. As an example, "HMI:Display|10s@/myvar" updates variable every 10 seconds.

SVGHMI: cosmetic fixes + removed dead code

SVGHMI: allow widgets to disable clipping on variables given with min and max. Setting this.clip = false disables clipping.

SVGHMI: allow designating widget's sub-elements as main element child rather than descendant. Names staring with "/" in yslt call to labels() only match direct widget childs.

SVGHMI: add localized Date and Time support to sprintf.js. Use with "%D" or "%2.1D" format style.

Minor changes to README.md

wxPython4 sequels: usual naming problem in grid cell change events, non kw-args to menu.Append and event not being skipped.

Tests: Fix missing <br/> in generated html report.

Tests: add HTML report generation and a workaround to bad exception handling in sikuli.

In case of exception in python code, and since a thread is running
to observe stdout, sikuli was never terminated after an exception.
Unfortunately sys.exepthook doesn't work in that version of jython/sikuli.
Test are now written inside functions witch are passed to run_test to deal
with exception.

Tests: refactored sikuli based test

IDE: Postpone execution of keyboard shortcut commands when given while previous command is still being executed, to prevent CTR/builder jamming.

IDE: in case of unhandled exception, write bug report to given log file, so that test report can have it.
