Alter World to use Persistence instead of storing data in historical figures.
Fake historical figures will be converted to the new format when a world is loaded.
Added plugin_save and plugin_load functions to the plugin API.
Made the weird int7/int28 code that was in the old persistence API slightly safer.
This moves code intended to infer biome type currently living in a
couple of plugins into the Maps module, so that this code can be shared
more easily by multiple plugins, as discussed in #1392.
Also modified Core/Console a bit to get this to actually produce output on
Travis (DFHACK_DISABLE_CONSOLE now allows console output, just not input)
Squashed merge from lethosor/tests
The change allows correct and optimized incremental builds with VC and
ninja but unix makefile backend will rebuild everything if anything
changes in structures.
ninja has a single build file which avoided issues if multiple targets
depend on same files. But Unix Makefiles generator user recursive make
which requires each ADD_CUSTOM_COMMAND to have only one target depending
on them.
Then makefile generator also has stupid rule that it touches all
secundary output files if primary file has been updated.
It was surprising hard to find a version that actually works correctly
for both issues. Solution is using BYPRODUCTS and refactoring command
and target dependencies.
As a bonus this change now allows build to work from source tarball if
the tarball includes git-describe.h.
Using add_custom_command allows cmake to track dependency from command
to git-describe.h that is implicit dependency of DFHackVersion.cpp.
The change also fixes issues if there is multiple build directories and
git-describe.h missing but git-dsecribe.h.tmp is present.
_exit seems to run dll unloading code which calls static destructors.
Standrd requires std::_Exit not to call destructors which makes using it
attractive in case MSVC actually follows the standard.
I'm not sure if calling GetModuleHandle in static construction is safe.
But I assumme it is and works correctly.
There is still potential issue that documentation can be understood
meaning that the HMODULE will resolve only symbols from exe while
RTLD_DEFAULT resolves all global symbols.
plen+cooked_cursor==cols => begin = -1 which is passed to substr. The
sign is incorrect as code should be removing a character from begin
instead of trying to add a character.
The runtime debug print filtering support dynamic debug print selection.
Tis patch only implements basic core support for filtering. The commands
to change the runtime filtering settings will be added in a following
patch.
But even with only this one can change filtering settings by editing
memory using a debugger. It can even be automated by using gdb break
point commands.
- Use port from remote-server.json in dfhack-run
- Make DFHACK_RUN environment variable take priority over remote-server.json
- Log current port to stderr
I often want to see multiple items quickly when trying to figure out
what states actually matter to an issue that I debug. I decided to make
it easier to quickly dump df structures with substructures and
containers. It will generate large amount of data which can be sometimes
slow to process manually. But processing can be automated using
dfhack-run lua ^<df data to inspect> and pipe to other tools (eg grep,
sed, perl, sort, uniq etc)
The bools could use acquire&release memory order or even relaxed but I
didn't think code was worth auditing for such low level optimizations.
Sequantial consistent is fast enough but much harder to use incorrectly.
The timeLast is protected by CoreSuspender lock. plugin_update is only
called when CoreSuspender lock is held.
The last_menu is protected by trackmenu_flg loads and stores.
I noticed an extra null when trying to grep dfhack.run ls output.
std::string manages null byte at end(). Pre C++11 didn't require null
termination for std::string but C++11 add the null termination to make
c_str() and data() truely const. It is undefined behavior to modify the
internal null termination but this modification sets the null to null.
The old CoreSuspender requires processing from Core::Update to allow
commands execute. But that causes issues if Core::Shutdown wants
quarentee cleanup order with std:🧵:join. Fixing shutdown ordering
adds too many branches to already fairly complex code.
I decided to try to refactor CoreSuspender to use simpler locking
locking using a std::recusive_muted as primary synchronization
primitive.
To help control when Core::Update unlocks the primary mutex there is
std::contition_variable_any and std::atomic<size_t> queue lenght
counter.
The last state variable is std::atomic<std:🧵:id> that is used to
keep track of owner thread for Core::IsSuspended query.
This should be merged only just after a release to make sure that it
gets maximum testing in develop branch before next release.
