IDE: py3.10 related float/int fixes in debug plots

Move tests/project/modbus in exemples.

Python3 fixes for Modbus Web Settings

Fix template conflict in XSLT with lxml>=4.9.0 again

Tests: Add preliminary IEC-61131 language test, to be continued.

Test sets BEREMIZ_TEST_CYCLES in order to speed-up TON duration test.

Tests: Add time emulation feature for tests with BEREMIZ_TEST_CYCLES CFLAG.

Adding BEREMIZ_TEST_CYCLES=1000 in a project's CFLAGS will:
- run 1000 cycles with no pause
- emulate time flowing normaly for PLC code
- exit PLC thread

This allows:
- testing standard library blocks that deal with time without having to wait
- unit testing and code coverage with POUs that uses time

IDE: fix exception when re-opening previously closed tab

Same as commit with same message, this time for tabs that are not POUs editors.

IDE: fix again ruberband with gtk3.

DC logical functions are now disabled when using GTK3.
Apparently using XOR was still having an effect.
Use regular black pen with no logical funciton instead.

Merged from default

merged

Modbus web configuration: add check for valid delay and period parameters

IDE: Fix missing highlighted element in diagrams when using GTK3

- wx's logical function does not work on gtk3, and highlighting relies on it
- skipping logical funciion at all "works" but this now makes highlight opaque
- no easy fix for highlight transparency since emulated with AND Wx logical function
+ added other highlight related cosmetic fix.

Merged default in wxPython4 branch

Linux runtime: overrun detection for real-time timers and for plc execution.

If real-time timer wakes-up PLC thread too late (10% over period), then
warning is logged.

If PLC code (IO retreive, execution, IO publish) takes longer than requested
PLC execution cycle, then warning is logged, and CPU hoogging is mitigated
by delaying next PLC execution a few cylces more until having at least
1ms minimal idle time.

Fix typo in toolchain_gcc.py : LDLAGS -> LDFLAGS

Merged from default

Merge.

SVGHMI: add two more simple widgets to default widget library

Tests: Use TESSERACT_LSTM_COMBINED, LSTM + Legacy OCR mode in Sikuli, more stable results.

Merged default in wxPython4 branch

Runtime: Fix bugs in Linux target.

- next occurence absolute time computation failing on 32-bit because of casting
- PLC thread was started before period was set, potentially passing uninitialized timespec to clock_nanosleep()

runtime: Change Linux target to use clock_nanosleep instead of timer (better rt-preempt perf).

Linux runtime: fix thread waiting on wait_RT_to_nRT_signal not being waken-up when delete_RT_to_nRT_signal is invoked.

Tests: docker image needs tesseract4, but opencv lib since sikuli.jar already contains it.

More explicit default value for generic makefile target command. Assume Makfile is located in project_files

IDE: prevent IDE/CLI process surviving to sys.exit() by using deamon threads to monitor external processes output streams.

Tests: allow overriding local host's hostname with BEREIS_LOCAL_HOST env variable.

Tests: IDE: explicitely wait for build success rather than just stdout to become silent.

Tests: Fixed wrong path (relative to $HOME) in CLI tests.

Tests: OPCUA tests can now use OPCUA_DEFAULT_HOST environment variable to force host to something else than "127.0.0.1" or "localhost"

IDE: fix segfault when unselecting network discovery in URI editor

IDE: fix exception when showing project's context menu in case of empty clipboard (wxpython4).

Tests: Fix dockerfile not finding locales.

cosmetic fix

Tests: use expedited termination of IDE with SIGTERM instead of normal close

Work around test not finishing when IDE ask for confirmation on exit when
project is modified.

IDE: When receiving SIGTERM signal, kill runtime befor bailing out without saving.

Purpose is to allow expedited test termination.

Merged default in wxPython4 branch

Merged changes from default in wxPython4 branch

SVGHMI: fix XY graph init (consequence of earlier change) + reindent

Earlier change did modify the variables attributes (options) are stored in widget objects. XY graph uses variables' min and max to determine range.

SVGHMI: move declaration of "xmlns" javascript const so that widgets can use it.

This was broken in earlier commit, when changing initial execution order because of implementing websocket reconnect.

SVGHMI: add Page assignment use case in svghmi test project.

Marged default in wxPython4

SVGHMI: update generated xslt

SVGHMI: avoid Widget's member name colision in between enable expressions and assignments.

SVGHMI: Add arbitrary variable assignment when entering Pages

Usage similar to Assign widget.
Required instanciating PageWidgets for each page, so that assigned variables can be subsribed.

SVGHMI: update generated XSLT

SVGHMI: fix periodic reconnect triggering watchdog

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

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.

SVGHMI: cosmetic fix in Back widget

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.

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: 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.

IDE: Fixed About dialog exception on Windows, and typo in about dialog's content.

runtime: fix bugs introduced in previous commit, and refactor some code

Runtime: wx.app.mainLoop and twisted reactor now share main thread with runtime.Worker.

This fixes exception when invoking python interactive shell from Runtime's tray
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: 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.

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.

Merged default's changes in wxPython4 branch

Tests: fix project edit test sikuli IDE test.

Background click based on bitmap matching doesn't work.
Grid dots are not good match candidates.
Rendering probably affected by virtual display's bpp or rasterizer approximations.

runtime, retain: remove forgotten debug code.

Runtime: removing dead code

IDE: removed one (last ?) wx.NewId() that was called on each opening of project tree popup menu

Tests: Re-introduced pytest based tests. Fixed them a bit, commented-out otherwise. Application tests only runs with logging test, and PLCOpenEditor tests seem broken.

Tests: Enhance robustness of stdout driven waiting state in Sikuli based tests.

Some tests were randomly passing, because from time to time waiting for idle was skiped. It was combination of multiple problems :
- buffering on stdout (now use readline + flush for each write to log)
- it is sometime required to wait for activity before waiting for timeout added "WaitForChangeAndIdle" to "stdoutIdleObserver"

Tests: add an IDE test that relies on image matching.

Tests: re-introduce xvfb+x11vnc target in Makefile : xvfb_sikuli

Fix sequel of wxPython 4 port : double click on tab wasn't maximizing and was showing exception.

Tests: Makefile's PIPESTATUS turned into small letters (wrong vim shortcut ?) leading to always passing tests.

Tests: Various enhancements in Makefile and sikuli common python code.

Tests: Added BEREMIZPYTHONPATH to point to Python interpreter to use for tests.

Documentation/comment fix.

IDE: Fix one more sequel of wxPython4 port : typo in editors/TextViewer.py

Tests: Add a Makefile variable to allow changing standalone headless X server command (Xvfb by default)

Merge default head that was only merged in wxPython4

merged default

Add Docker image definition as reference platform to run IDE tests.

Tests: added tests/Makefile and a first test in tests/ide_tests. Test requires sikuli and Xvfb or Xnest.

IDE: Add -l or --log command line parameter to give a file where all content witten to console window will be appended. File can be /dev/stdout.

Merge default

IDE: follow-up on change in 83ed4ea362db - added workaround when matiec generated files contain unexpected characters.

Runtime : force using monotonic time in Timer (threading). Prevent watchdog to trigger when changing system time.

SVGHMI: remove debug code

SVGHMI: update generated XSLT

SVGHMI: fix again appication of frequency value when given in label. Use it on PushButton instance in svghmi test.

TESTS: moved non-automated tests Beremiz projects stored as directories in /tests to new directory /tests/projects

Create README.md in tests

SVGHMI: update generated xslt, and svghmi test project files

SVGHMI: Add pushbutton widget, that can take reflect short press in variable, but has no garantee on consistency.

SVGHMI: Fixed support for frequency parsing in widget label

Merge

SVGHMI: update generated xslt

SVGHMI test: add special commandline to launch chromium as new intependent window, without GPU acceleration.

SVGHMI: add syntax for widget update frequency in widget label: HMI:WidgetType|freq:arg0:arg1@path

OPC-UA client: "static" class was forgotten for open62541 client structure preventing multiple client.

OPC-UA: cosmetic fix and armless typo

Merged default in wxPython4, include runtimeLists

Merge

SVGHMI: added ListSwitch widget

Merged RuntimeLists branch

Close RuntimeLists branch

Fix bug introduced in previous commit : dual link list wasn't append and remove wasn't implemented correctly. Removed debug code, enhanced variable names and comments.

SVGHMI: optimization of C part : stop traversing the whole HMI tree, use dual linked list for subscriptions and single linked list for changes from HMI. Intermediate commit, still crashing in some cases.

Xenomai runtime: ensure that __DEBUG global variable is set when resuming debug.

SVGHMI: Adapt svghmi.c to changes in UnpackVar

Runtime: Now retain uses a list based on data available in VARIABLES.csv instead of traversing the whole instance tree looking for RETAIN flag.

RUNTIME: Variable forcing now uses limited list and buffer instead of systematical instance tree traversal and in-tree "fvalue" to keep track of forced value for pointed variables (external, located). Pointer swapping is performed when forcing externals and located, with backup being restored when forcing is reset. Retain still uses tree traversal.

RUNTIME: Variable trace now uses limited list and buffer instead of flags in instance tree that was requiring systematical instance tree traversal, and worst size buffer. Forcing and retain still use tree traversal.

SVGHMI: more accurate filtering of elements to unlink or not

OPC-UA client: generated code now take UA_Variants on the stack directly, avoid useless allocation on write, and unalloc implicitely allocated data on read
