There is a minor chance that console or init thread would access already
freed memory when core is shutting down and cleaning up state. To avoid
any danger of having random bugs caused by the potential data race I
decided to make sure the shutdown code waits for the thread to exit
first.
Windows change is completely untested. It is purely based on msdn
documentation.
I noticed that tthread is missing some c++11 features that make thread
handling code a bit easier. To be able to use those features I decided
to convert Core.cpp to use equivalent standard classes.
This patch has no functional changes.
command-prompt viewscreen may affect command execution if they are
looking for UI state. To make commands execute simillary to hotkeys or
console commands the viewscreen needs to removed from the top position.
Fixes#1194
Inventory items have stale position information. The coordinates can be
very old if item is owned and continuesly carried for long time. The fix
checks if item is carried. To avoid filtering carried items that are
assigned (containers) to the stockpile the assignment needs to be
checked.
Fixes#1288
The Screen::show takes ownership of the screen pointer. I decided to
switch the parameter to std::unique_ptr to make the pointer ownership
explicit. The unique_ptr then provides automatic screen destruction in
Screen::show unless pointer is inserted or is already in the linked list
that is managed by df.
G++ generates structure debug symbols for a few df namespace classes to
generated stub source files. I decided to test how much symbols from
those files would increase binary size. When the result was about double
size I decided to add cmake configuration option to let user easily
select if they prefer complete symbols or reduced size.
