Move most of the media-related code in client.cpp into a new class
ClientMediaDownloader (clientmedia.cpp, clientmedia.h). Among other
things, this class does the following things:
- Download [remote_server][sha1] instead of [remote_server][name]. This
is to support servers that provide the same file name with different
contents.
- Initially fetch [remote_server]index.mth. This file should follow the
Minetest Hashset format (currently version 1) and contain a list of SHA1
hashes that exist on the server.
- The list of needed SHA1s is uploaded (via HTTP POST) when index.mth is
requested, so servers can optionally narrow down the list to the needs
of the client.
- If index.mth is missing (HTTP response code 404), we enter compat mode,
fetching [remote_server][name] as before this commit.
- remote_server can now contain multiple servers, separated by commas.
The downloader code attempts to split requests between the different
servers, as permitted by each server's index.mth. If one server claims
to have a file but actually doesn't (or something fails), we ask a
different server that also claims to have it.
- As before, when none of the remote servers provide a particular
file, we download it via the conventional method, i.e. using
the minetest protocol: TOSERVER_REQUEST_MEDIA / TOCLIENT_MEDIA.
- Bugfix: Every downloaded file's SHA1 is now verified against the SHA1
announced by the minetest server (before loading it and inserting it
into the file cache).
- Bugfix: Only send TOSERVER_RECEIVED_MEDIA when we actually have all
media. This should fix#863.
* If client count is unbearable, immediately delete denied clients
* Re-prioritize the checking order of things about incoming clients
* Remove a huge CPU-wasting exception in ReliablePacketBuffer
On the lua side, notably minetest.env:<function>(<args>) should now
be replaced by minetest.<function>(<args>).
The old way is and will stay supported for a long time.
Also:
Update and clean up lua_api.txt (by celeron55)
Move EnvRef to lua and remove add_rat and add_firefly (by kahrl)
Add separate src/util/CMakeLists.txt, other minor fixes (by kahrl)
Spawn single particles or make use of ParticleSpawner for many randomly spawned particles.
Accessible in Lua using minetest.spawn_particle and minetest.add_particlespawner.
Increase Protocol Version to 17.
Conflicts:
src/clientserver.h
- Neatly placed all emerge related code into a new file, emerge.cpp
- Greatly cleaned up the code in EmergeThread::Thread()
- Reworked Emerge queue. Now an actual std::queue of v3s16 block positions
- Removed the completely unnecessary map of peer ids requesting blocks
settings.h: added function to return all keys used in settings, and a
function to remove a setting
mods.{h,cpp}: added class ModConfiguration that represents a subset of the installed mods.
server.{h,cpp}: server does not load add-on mods that are disabled in
the world.mt file. mods are disabled by a setting of the form
"load_mod_<modname> = false". if no load_mod_<modname> = ... setting
is found, the mod is loaded anyways for backwards compatibilty. server
also complains to errorstream about mods with unstatisfied
dependencies and about mods that are not installed.
guiConfigureWorld.{h,cpp}: shows a treeview of installed add-on mods
and modpacks with little icons in front of their name indicating their
status: a checkmark for enabled mods, a cross for disabled mods, a
question mark for "new" mods
Mods can be enabled/disabled by a checkbox. Mods also show a list of
dependencies and reverse dependencies. double-click on a mod in
dependency or reverse dependency listbox selects the corresponding
mod. Enabling a mod also enables all its dependencies. Disabling a mod
also disables all its reverse dependencies.
For modpacks, show buttons to enable/disable all mods (recursively,
including their dependencies) in it.
Button "Save" saves the current settings to the world.mt file and
returns to the main menu. Button "Cancel" returns to main menu without
saving.
basic keyboard controls (if the proper widget has keyboard focus):
up/down: scroll through tree of mods
left/right: collaps/expand a modpack
space: enable/disable the selected mod
