* Use a specialized connection object
* Copy the Player object less frequently
* Use a randomly generated serial key for shard auth
* Refuse invalid shard connection attempts
* Clean up connection metadata when a Player joins the shard
* Prune abandoned connections when they time out
This prevents logic errors related to being in chunk 0 0 0.
Also:
* Moved some duplicated chunk teleportation logic to a new helper
function
* Made ChunkPos into a proper class so it can default to INVALID_CHUNK
when default-initialized
* Reversed the inclusion order of Chunking.hpp and Entities.hpp to work
around problems with type definitions
The client will actually do this itself when clicking the quit button in the tilde menu, but for the idle timer the connection would remain open until the game is closed.
* Download and list artifacts after build
* Add commit hash + file extension to artifact name
* Initial SSH implementation
* Don't build artifacts for PRs
* Fetch endpoint from secret
* Zip artifacts before uploading to CDN
* Use short SHA in archive names
In our original implementation, quest item drops were rolled on the
spot, so the chances of getting two quest items for different missions
in a single kill (where both missions have you kill the same mob) were
independent of each other.
When we made quest item drop chances shared between group members so
players doing missions together would progress at the same rate, we
accidentally linked the quest item odds of different missions together.
This change makes it so that the odds are per-task, so they're shared
between different group members doing the same tasks, but distinct for
different tasks being done by the same player.
* Removed a redundant failure case in endTask()
* Fixed a misleading comment in startTask()
* Removed a redundant level check in updateFusionMatter()
* Cleared up misleading comment and code layout in taskEnd()
* Removed unnecessary comment in mobKilled()
Couldn't get a reliable repro, but this is probably what that bug was.
It's not very throughly investigated, but we'll be tweaking those parts
of the codebase anyway, so we can examine if there's a deeper issue
later.
* Restrict fcntl() to only the flags we need
* Non-fatally deny tgkill() and rt_sigaction() so that segfaults don't
result in a SIGSYS. They're debuggable either way, but this way it's
clearer what the issue is right away.
* Allow truncate() and ftruncate() for sqlite's alternate journal modes
* Slight macro cleanup
* Add missing colon in a DB log message
We don't need to worry about compilation problems arising if glibc or
musl-libc add their own wrapper for the seccomp() syscall in the future.
Ours will/would just silently take precedence over the external one
without interfering with compilation. This should work regardless of
whether libc uses weak symbols and regardless of whether libc is
dynamically or statically linked into the executable. The wrapper's
signature has been stripped of its static and inline qualifiers, as it
must match the exact declaration the libc headers will/would use.
Further, if a pre-compiled binary is run on a system which genuinely
doesn't support seccomp(), it'll just return ENOSYS and the server will
terminate with an error. The user can then just disable the sandbox in
the config file. We don't need any special logic for that scenario.
Adding the assembly source files to the build system(s) would be more
trouble than it's worth, considering we don't make 32-bit builds for
much other than satisfying our curiosity.
There are some network configurations in which it's undesirable; such as
reverse tunneling through ssh. These are obscure enough to allow leaving
the option undocumented (in the example config file).
