fix issue with sometimes wrong return code of ProcessLogger


As a result of wrong return code Beremiz gives folowing traceback:
Traceback (most recent call last):
File "./Beremiz.py", line 850, in OnMenu
getattr(self.CTR, method)()
File "/home/developer/WorkData/PLC/beremiz/beremiz/ProjectController.py", line 925, in _Build
IECGenRes = self._Generate_SoftPLC()
File "/home/developer/WorkData/PLC/beremiz/beremiz/ProjectController.py", line 568, in _Generate_SoftPLC
return self._Compile_ST_to_SoftPLC()
File "/home/developer/WorkData/PLC/beremiz/beremiz/ProjectController.py", line 661, in _Compile_ST_to_SoftPLC
C_files.remove("POUS.c")
ValueError: list.remove(x): x not in list

The problem is that both threads (for reading stdout and stderr) call self.Proc.poll(),
that updates internal returncode field. This call is done without any locking and the first thread gets correct result,
but other gets 0 as retval. If 0 gets thread, that afterwards calls callback finish, then wrong return code is returned
to the parent. Now only the thread with a callback polls for the return code, other thread just checked local value.

Additionally function spin() waits now until all threads finish reading their pipes, so the results are always correct.

Fix error about missing attribute 'timeout' that happens sometimes during compilation

The fix [1476:49f1763a5613] of the problem with following trace was wrong.
Traceback (most recent call last):
File "./Beremiz.py", line 1229, in run_with_except_hook
run_old(*args, **kw)
File
"/home/developer/WorkData/PLC/beremiz/beremiz/util/ProcessLogger.py",

"/home/developer/WorkData/PLC/beremiz/beremiz/util/ProcessLogger.py",
line 169, in finish
if self.timeout: self.timeout.cancel()
AttributeError: ProcessLogger instance has no attribute 'timeout'
The problem was that compilation process was finished before the timeout attribute is set.
Now timeout is set before launcing of compilation process.

fix copying elements with non-latin content like comment element, or
variables with description in non-latin character set

before any non-latin text was converted after copying to strings like 'Это...'

fix issue that if functional block is dragged from project panel into
ST text editor and in dialog 'Please enter a block name' button
'cancel' is pressed, despite of cancel text about drag'n'dropped type
is pasted in ST program.

fix regression introduced by changeset: 1431:28e9d479aa65 [Use '-p' command line option when running matiec (iec2c)]

Variable matiec_flags in c_ext.py and PythonFileCTNMixin.py is not
used for flags for matiec (IEC to C compiler) actually, but it's used
to compile C-code generated for extensions using normal C-compiler,
like gcc.

fix display of ARRAY fields inside of structure data types.

Previously ARRAY fields in structures were displayed, for example,
like 'ARRAY [1..2] OF ARRAY' instead of 'ARRAY [1..2] OF INT'. Because
of this error the array type can be really edited.

fix Traceback if search icon on library panel is clicked, when no
category/item is selected in the library.

The problem is here, that if nothing is selected method GetSelection()
returns root item, that doesn't have any python data associated with it.
This issue seems to be wx3.0 specified, because it doesn't exist
with wx2.8 on Windows.

update Russian about Beremiz dialog window

fix issue, that was impossible to change time interval for cyclic
tasks, when wx 3.0 is used

fix deprecation warnings about accessing properties m_x, m_y of wxKeyEvent

update Russian translation

add i18n for some strings in DiscoveryDialog, DurationEditDialog, ProjectDialog and CodeFileEditor

fix wrong Row number in DiscoveryDialog.py that caused following traceback:

increase height of some dialog windows so they have enough space for buttons

add translation into Russian for dialog window "About PLCOpen Editor"

add translation of "about" window into Russian

make About and Find dialogs have the same icon as main Beremiz window

all child windows will take the parent's icon, if no other is specified.

fix splash loading with wx3.0

Previously only gray square was shown. Apparently to show splash screen several calls of wx.Yield() are necessary.
Unfortunately splash.IsShowOnScreen() returns always 1 regardless of whether splash is on the screen or not.
this fix is a dirty hack. It just process all events after splash is created during 0.3 seconds.

add i18n for couple of strings in TextViewer.py
add source file for Russian translation
update messages.pot and app.fil
update Russian translation

increase height for ConnectionDialog and ArrayTypeDialog to have
enough place for buttons

add Russian translation

bitmap in wx3.0 doesn't have useAlpha() method

Suppress WXDEBUG assertions, as happens by default with wx2.8. This is
necessary for wx3.0
