Andrey Skvortsov <andrej.skvortzov@gmail.com> [Sat, 09 Jun 2018 17:13:16 +0300] rev 2181
Add command line argument to run linter only on changed files
./tests/tools/check_source.sh --only-changes
It's recommended to run check_source.sh automatically on each commit,
so the rules are always enforced.
Even better is to use docker for that, so the versions of pep8 and
pylint are the same as on pipeline server.
To do this couple of lines should be added into repository's hgrc file.
[----------- cut from .hg/hgrc------------------]
[hooks]
precommit.linter = ./tests/tools/check_source.sh --only-changes
# precommit.linter = docker run -it --volume=$PWD:/beremiz --workdir="/beremiz" --volume=$PWD/../CanFestival-3:/CanFestival-3 --memory=1g --entrypoint=/beremiz/tests/tools/check_source.sh skvorl/beremiz-requirements --only-changes

Don't use fixed width labels in WAMP and PYRO dialogs
This causes problems if labels are translated into other languages and
width wasn't enough.

Fix internatialization in UriLocationEditor, PYRO dialog and Modbus configurator

Add copyright headers to retain implementation for GNU/Linux and Win32

Drop support for wxPython 2.6 and below

Autoresize UriLocationEditor dialog window

Fix compilation problem in case of TARGET_LOGGING_DISABLE turned on and TARGET_DEBUG_DISABLE turned off
Andrey Skvortsov <andrej.skvortzov@gmail.com> [Thu, 07 Jun 2018 14:04:45 +0300] rev 2174
Use the same retain implementation for Win32 targets
Currently plc_Win32_main_retain.c is exact copy of
plc_Linux_main_retain.c, because it's not possible to use symbol
links.
It'd be nice in the future to have possibility to modify targets.code.
Andrey Skvortsov <andrej.skvortzov@gmail.com> [Thu, 07 Jun 2018 13:45:35 +0300] rev 2173
Add retain basic implementation on GNU/Linux
Retain is saved in file and backup of this file is done every time.
File isn't saved on every PLC cycle to avoid high I/O load.
By default, retain is saved every second and on PLC stop/shutdown.
It's possible to override retain flush period by using CFLAGS option
in project's settings. For example, for 0.5 seconds period
use "-DFILE_RETAIN_SAVE_PERIOD_S=0.5".
Andrey Skvortsov <andrej.skvortzov@gmail.com> [Fri, 01 Jun 2018 15:46:17 +0300] rev 2172
Add helper function GetRetainSize()
it will be useful for retain implementations.
Andrey Skvortsov <andrej.skvortzov@gmail.com> [Fri, 01 Jun 2018 12:21:37 +0300] rev 2171
use CLOCK_MONOTONIC instead of CLOCK_REALTIME for timer setup
CLOCK_REALTIME is a wall clock, that could change back and forth (user
changes system time, winter/summer time, NTP corrections and so on).
For real-time application CLOCK_MONOTONIC should be used, it doesn't
have such jumps.

Add function example to first_steps example
It'll be used in documentation to show how to create function in
Beremiz.

fix type introduced by f33942053466 (fix pylint warning "(undefined-loop-variable) Using possibly undefined loop variable 'X'")

Build by default with optimization level -O2 for GCC
before -O0 was used by default, that caused pretty bad performance.
Amd64, i6700k, 4200MHz, GNU/Linux (non-RT kernel), gcc 7.2.0
-------------------------------------
Optimization | EN/ENO |no EN/ENO |
-------------------------------------
default | 11 | 9.5 |
-O3 | 3.9 | 5.2 |
-O2 | 4 | 4.8 |
-Os | 4.1 | 3.5 |
-Ofast | 3.9 | 5.2 |
-------------------------------------
ARM, BBB Cortex-A8, 600Mhz, GNU/Linux, gcc 4.6.3
-------------------------------------
Optimization | EN/ENO |no EN/ENO |
-------------------------------------
default | 273 | 226 |
-O3 | 141.8 | 106.2 |
-O2 | 142 | 107 |
-Os | 152.5 | 112.2 |
-Ofast | 141.7 | 106.2 |
-------------------------------------
For embedded systems with size constaints (like Cortex-Mx, AVR and so
on) I usually use -Os. It gets pretty good results. For
GNU/Linux-based systems -O2 is usually a good choice, as you see the
test results.
