Notable changes:
- tpt.{input,throw_error,message_box,confirm} have been superseded by ui.begin{Input,ThrowError,MessageBox,Confirm}, each with an extra callback argument and no blocking behaviour, but otherwise the same semantics as their predecessors.
- The "script not responding" error doesn't wait for user confirmation anymore, it fires without asking. Future exercise: maybe let the user configure the timeout.
- Remove the confirmPrompt argument of tpt.getscript; this also means it unconditionally fails if the destination file exists.
Achieved by adding a new element property called CarriesTypeIn, whose bits signal to save loading code which properties of particles of the element class in question carry element IDs. The bits in this property are numbered the same way as sim.FIELD_* constants for consistency. One would signal from Lua that a custom element carries element IDs in its tmp like this:
elem.property(id, "CarriesTypeIn", 2 ^ sim.FIELD_TMP)
"Carrying an element ID in a property" is to be interpreted as follows: the property is treated as a combination of a PMAPBITS-bit (so, currently 9-bit) unsigned integer lower part holding an element ID and a 32-PMAPBITS-bit (so, currently 23-bit) signed integer upper part holding whatever makes sense for the element. CONV, for example, uses this signed integer in its ctype as the extra "v" parameter for particle creation.
A bug existed before where certain events would not update Engine's lastTick. If the sim was lagging hard, then this could cause "script is not responding" errors to appear in unintentional situations.
The starting execution time is tracked in LuaScriptInterface instead now, and set in tpt_lua_pcall
Request ownership is no longer flaky. Requests are now owned by the code that makes requests, and Requests and the RequestManager co-own RequestHandles. RequestManager disowns a RequestHandle if it's done with it or if Request code reports that it's no longer needed.
All libcurl code has been moved to RequestManager. This is nice because once NOHTTP is removed, we can add any number of RequestManager implementations, for example one for Android.
Client outliving RequestManager is still a problem, this will have to be addressed later.
Some operator[]s that know the size of the container they wrap like to assert(index >= 0 && index < size), which is bad for us because we sometimes use &container[size]. This is not undefined behaviour until that pointer is dereferenced, but certain operator[]s choose to ignore this fact and err on the side of caution. The solution is to use &container[0] + size instead of &container[size].
Also write PNGs with libpng, and BMPs with SDL, and have the renderer only generate a large PNG thumbnail, and disable HTTP/2 multiplexing for now so we don't get banned when loading avatars.
simon pls reply to the stupid emails already.
Also restructure meson.build and the ghactions workflow a bit, and enable -ffunction-sections and -fdata-sections.
Note that starcatcher uploads have not been tested and most likely don't work.
This fixes bugs like "type\0hello mom" being a property name sim.partProperty accepts and half-fixes bugs like text formatting codes making gfx.drawText exit prematurely.
Also clear SaveRenderer graphics cache along with the main Renderer's when needed, and revert to built-in element callbacks rather than nothing at all when assigning nil to a callback slot in Lua.
Allows finer control over whether you want none included or not.
Fixes some invalid things being allowed for element 0 in legacy lua api
Fixes {ctype} signs showing 0 instead of NONE
Though I'm quite sure nobody actually cares about that table. It's been broken for a
very long time.
The PROP tool now properly calls part_change_type when type is being set.
