This so names from other clients are known valid in the client as well, instead allowing some compromised/bad server to potentially crash clients upon certain expectations.
Strictly seen the comment is true, as it says 'e.g.', but it is
misleading. The server name is just that: the name of the server
as configured. No need to mention advertising.
When ever you saw this debug lines (which you never should), they
showed an empty address. It is also not very useful to have, as it
always points to a known server anyway.
The original idea was that people could find a server they could
talk in their native language on. This isn't really used in that
way. There are several reasons for removing this:
- the client also sends his "language" to the server, but nothing
is doing anything with this.
- flags are a bad way to represent languages, and over the years
we had several (rightfully) complaints about this.
- most servers have their language set to "All", and prefix the
servername with the language it is about. This is a much more
efficient way to do the same.
All in all, this feature should go back to the drawing board.
Maybe it could work in another form, but this form is not it.
The idea back in the days was nice, but it never resulted in
anything useful. Most servers either read "(loaded game)" or
"Random Map", neither being useful. It was meant for heightmaps,
so you could find a server that was using a specific one .. but
there are many things wrong with that idea. Mostly, servers tend
to save and load savegames from time to time, after which the
original heightmap used was lost.
All in all, removing map_name all together is just better.
The server information panel was scaled by GUI scale, which could result in a panel that is longer than the server list. This height difference is then maintained when the window is resized to fill the screen.
Instead, specify the minimum size by number of text lines and (summed total) padding.
Use status >= STATUS_AUTHORIZED as the state criteria for all cases
where updates about other clients are sent.
This avoids the case where a client is informed that another client
has joined but not informed when it later quits, resulting in
stale entries in the client list window.
Basically, modal windows had their own thread-locking for what
drawing was possible. This is a bit nonsense now we have a
game-thread. And it makes much more sense to do things like
NewGRFScan and GenerateWorld in the game-thread, and not in a
thread next to the game-thread.
This commit changes that: it removes the threads for NewGRFScan
and GenerateWorld, and just runs the code in the game-thread.
On regular intervals it allows the draw-thread to do a tick,
which gives a much smoother look and feel.
It does slow down NewGRFScan and GenerateWorld ever so slightly
as it spends more time on drawing. But the slowdown is not
measureable on my machines (with 700+ NewGRFs / 4kx4k map and
a Debug build).
Running without a game-thread means NewGRFScan and GenerateWorld
are now blocking.
In other words, it should only (!) return true if A comes for B.
This promise was broken for the situation where two values are
identical. It would return true in these cases too. This is of
course not possible: if two values are identical, neither come
before the other. As such, the sorter was not imposing strict
weak ordering relations.
libstdc++ handled this scenario just fine, but libc++ crashes
badly on this, as it allowed comparing of [begin, end] instead
of [begin, end).
libc++ considered this not a bug (and by specs, they are correct;
just this way of crashing is of course a bit harsh):

Strictly seen, there are "N" people -waiting- in front of you
in the queue, but it is nicer to show "N + 1" for the person that
is currently downloading the map. Avoids it showing:
"0 clients in front of you". That just feels a bit off.
SendError() notifies all clients of the disconnect. This calls
CloseConnection() at the end, which also notified the clients
of the disconnect. Really no need to do it twice.
The status NETWORK_RECV_STATUS_SERVER_ERROR is only set by
SendError(), so in case that is the status, don't let
ClientConnection() send another notification.
If a server is compatible, it falls back to sorting by clients.
This used to be in reverse, so full servers are on top. With
the codechange commit, this was removed by accident, and as
such empty servers were on top. This is silly.
This is a much better location for this button, as you send
money from one company to another company, not from player
to player.
This is based on work done by JGRPP in:
f820543391
and surrounding commits, which took the work from estys:
https://www.tt-forums.net/viewtopic.php?p=1183311#p1183311
We did modify it to fix several bugs and clean up the code while
here anyway.
The callback was removed, as it meant a modified client could
prevent anyone from seeing money was transfered. The message
is now generated in the command itself, making that impossible.
Check if the job is still running two date fract ticks before it is due
to join, and if so pause the game until its done.
When loading a game, check if the game would block immediately due to
a job which is scheduled to be joined within two date fract ticks,
and if so pause the game until its done.
This avoids the main thread being blocked on a thread join, which appears
to the user as if the game is unresponsive, as the UI does not repaint
and cannot be interacted with.
Show if pause is due to link graph job in status bar, update network
messages.
This does not apply for network clients.
Apple Clang version 12 (bundled with Xcode 12) complaints about copying
small objects in range loop (-Wrange-loop-analysis introduced by -Wall).
This warning can be easily avoided by removing the reference from
the const pointer type.
Emscripten compiles to WASM, which can be loaded via
HTML / JavaScript. This allows you to play OpenTTD inside a
browser.

Remove static buffer form of NetworkAddress::GetAddressAsString.
This is used in multiple threads concurrently, and is not thread-safe.
Replace it with a form returning std::string.
CMake works on all our supported platforms, like MSVC, Mingw, GCC,
Clang, and many more. It allows for a single way of doing things,
so no longer we need shell scripts and vbs scripts to work on all
our supported platforms.
Additionally, CMake allows to generate project files for like MSVC,
KDevelop, etc.
This heavily reduces the lines of code we need to support multiple
platforms from a project perspective.
Addtiionally, this heavily improves our detection of libraries, etc.
Previously the internal content list was invalidated and sorted for
every new item added. Now the sorting is delayed until the GUI is
drawn, which means we only sort once per GUI tick.
Since the amount of incoming items per GUI tick is not controlled by
the GUI but rather by network speed, we were previously doing a lot
of duplicate work per tick, causing the mouse cursor to lag while
the list was initialized.
This commit adds the missing feature of allowing the server owner to
provide a reason for kicking/banning a client, which the client sees in
a pop-up window after being kicked. The implementation extends the
network protocol by adding a new network action called
NETWORK_ACTION_KICKED that is capable of having an error string, unlike
the other network error packages. Additionally, the kick function
broadcasts a message to all clients about the kicked client and the
reason for the kick.
If the game was started loading a savegame or scenario, auto-restart will load a new random map.
This is inconsistent with the case in which a heightmap was loaded, as in that case the heightmap is kept as a basis for a new game.
This proposal solves this heterogeneity be considering the originally loaded resource shall be kept, hence savegames & scenarios shall be reloaded
Fixes the following complaints:

In particular this crash can be observed when using the
bootstrap GUI to download the base graphics.
In ClientNetworkContentSocketHandler::OnReceiveContentInfo
ClientNetworkContentSocketHandler::callbacks is iterated, using an iterator
cb->OnReceiveContentInfo() is called (cb is of type BootstrapAskForDownloadWindow)
This calls new BootstrapContentDownloadStatusWindow()
This inherits from BaseNetworkContentDownloadStatusWindow
The constructor of which calls _network_content_client.AddCallback(this)
This reallocates the std::vector which is being iterated in ClientNetworkContentSocketHandler::OnReceiveContentInfo
This results in iter being invalid, and an assertion failure occurs shortly
afterwards due to its use in the next iteration of cb->OnReceiveContentInfo()
Adjust all locations where ClientNetworkContentSocketHandler::callbacks
is iterated to avoid problematic behaviour
The last use was for storing a list of memory blocks. As the way these lists are accessed is very
specific, it is easier to just write an explicit destructor instead of trying to exactly match the behaviour.
A conforming compiler with a valid <mutex>-header is expected.
Most parts of the code assume that locking a mutex will never fail unexpectedly,
which is generally true on all common platforms that don't just pretend to
be C++11. The use of condition variables in driver code is checked.
The use of std::none_of in network/core/host.cpp is driven by the non-const
comparison operator use by NetworkAddress. A future commit should address
the const_casts in that class to ensure const-correctness.
This is a C++11 feature that allows the compiler to check that a virtual
member declaration overrides a base-class member with the same signature.
Also src/blitter/32bpp_anim_sse4.hpp +38 is no longer erroneously marked
as virtual despite being a template.
This switch has been a pain for years. Often disabling broke
compilation, as no developer compiles OpenTTD without, neither do
any of our official binaries.
Additionaly, it has grown so hugely in our codebase, that it
clearly shows that the current solution was a poor one. 350+
instances of "#ifdef ENABLE_NETWORK" were in the code, of which
only ~30 in the networking code itself. The rest were all around
the code to do the right thing, from GUI to NewGRF.
A more proper solution would be to stub all the functions, and
make sure the rest of the code can simply assume network is
available. This was also partially done, and most variables were
correct if networking was disabled. Despite that, often the #ifdefs
were still used.
With the recent removal of DOS, there is also no platform anymore
which we support where networking isn't working out-of-the-box.
All in all, it is time to remove the ENABLE_NETWORK switch. No
replacement is planned, but if you feel we really need this option,
we welcome any Pull Request which implements this in a way that
doesn't crawl through the code like this diff shows we used to.
In 10 years there is no commit to change how BeOS works, and we
have no active maintainer for it. It is unlikely it works in its
current state (but not impossible).
With the arrival of SDL2 (and removal of SDL), BeOS is no longer
support. SDL2 suggests to use Haiku instead of BeOS.
In 10 years there is no commit to change how MorphOS works, and we
have no active maintainer for it. It is unlikely it works in its
current state (but not impossible).
With the arrival of SDL2 (and removal of SDL), MorphOS is no longer
support. There is an SDL2 port for MorphOS, but it is not maintained
by upstream SDL2, and nobody can currently test it out.
If anyone wants to re-add MorphOS, please do (revert this patch,
fix the problems, and create a Pull Request). If you need any help
doing so, let us know! It is not that we don't like MorphOS, it is
that we don't have anyone fixing the problems :(
When unpacking downloaded content, the downloaded .gz file was being opened with `fopen`, the OS file handle given to zlib, and then afterwards zlib told to close the file.
But the `FILE *` object was never closed with `fclose`, meaning the stdio library would have a hanging file object, whose file handle was now invalid or referred to a different file. This caused asserts during shutdown with Microsoft's C library in debug mode.
Fix this by properly duplicating the OS handle and `fclose`ing the `FILE *` object, before giving the handle to zlib.
-Codechange: Remove LAST_GRF_SLOT and MAX_NEWGRFS. Now NETWORK_MAX_GRF_COUNT is the only constant to specify the maximum number of non-static NewGRF.
-Codechange: Increase the number of file slots, effectively increasing the maximum number of static NewGRF and baseset GRFs.
