- 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
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.
Fixes#1066
Console::lineedit can return -1 to indicate input error and -2 to
indicate the program is closing. But most users don't check possible
unusual return values which can lead to exit hang.
I noticed that multibyte characters can mess up the console state
variables. I decided to add a minimal multibyte support to make sure the
input only collects complete valid multibyte characters in case user
enters them to console.
This change assumes that UTF-32 has one to one mapping between printed
characters and char32 indexes. But I remember reading there is a few
rare corner cases with accents where character might require multiple
4byte characters too. But this patch at least changes correct handling
from about 100 characters to 99% of unicode characters.
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.
