- Shallow-freezing of objects is never used in our codebase, so remove
that code path.
- Deep-freeze is bugged in recent versions of SpiderMonkey (see bug
https://bugzilla.mozilla.org/show_bug.cgi?id=1930258). Until a fix
and/or a better API is provided, reimplement this feature by
recusively freezing object properties.
- Add tests for the deepfreeze function.
When calling `Engine.PushGuiPage` a promise is returned. The promise is
settled when the "child" page is closed. That allows to `await` it
inside `async` functions.
Previously the callback was run right inside the call to
`Engine.PopGuiPage`. Now the continuation of the promise is called at
the end of the "tick".
This won't help performance. It will more likely make things worse.
Since gui pages aren't opened or closed that frequently, it doesn't
matter that much.
Refs: 86c151ebaa
For the engine side:
The promise is stored in the `CGUIManager::SGUIPage` (like previously
the callback). When the promise is fulfilled it enqueues a callback in
the `JobQueue` of the `JSContext`.

SPECTRE attacks mitigations were added to SpiderMonkey's JIT output in

For the most part, from profiling on my machine, this is from memory

This is a paradigm change for AI computation.
Historically, the AI was intended to be run in a separate thread from
the simulation. The idea was that slow AI wouldn't stop the renderer
from being smooth.
In that original design, the AI received a copy of the game world and
used that to run its logic. This meant the simulation could safely do
whatever it wanted in the meantime. This copy was done via AIProxy &
AIInterface.
This design ended up having significant flaws:
- The copying impacts the simulation negatively, particularly because
AIProxy subscribes to a lot of messages (sometimes sent exclusively to
it). This time cannot be threaded, and impacts MP games without AIs.
- Copying the data is increasingly difficult. Modifiers are a headache,
LOS is not implemented. Lots of logic is duplicated.
The intended benefits of the design also failed to realise somewhat:
- The AI was never threaded, and in fact, it is probably better to try
and thread Sim + AI from the renderer than just the AI, at which point
threading the AI specifically brings little benefit.
The new design is much simpler and straighforward, but this has some
side-effects:
- The AI can now change the simulation. This can be used for cheating,
or possibly for a tutorial AI.
- The AI runs in the same GC zone as the simulation, which may lead to
more frequent Sim GCs (but overall we might expect a reduction in
temporary objects).
- The AI state was essentially cached, so replacing some functions with
Engine.QueryInterface might be slower. The tradeoff should be balanced
by lower AIProxy computation times.
Future work:
- Threading some specific AI tasks could still be worthwhile, but should
be done in specific worker threads, allowed to run over several turns if
needed.
Technical note: the AI 'global' is in its own Realm, which means name
collisions with the same are not possible.
Other notes:
- The RL Interface uses the AI Interface and thus will gradually lose
some data there. Given that the RL Interface can now request data
however, this should be dine.

- the private data is accessed through a safer wrapper
- CreateJSObject returns an opaque type to allow easier extension &
prevent errors.
- The implementation of CreateJSObject is moved near the GUI Proxy
template instantiation, and both are wrapped in a convenient macro (this
makes it so that if you use the macro, you can't forget to overload the
method, and vice-versa).
- The common IGUIObject JS interface no longer needs to be repeated.
- All specialisations are again put in the same file, for improved
compile-time & clarity, given there are so few lines now.
- While at it, implement toSource which makes it possible to `uneval`
components (does the same as toString though).

This is the same commit as 4bb31f084e, reverted in 5d1899785a. Noted
issues were fixed.
Partial revert/fix of 2f19cf86d3 and 2567fee329.
Before this diff, it was possible for a mod containing a cache/ or a
config/ folder to get written to incorrectly.
The issue is VFS can map multiple directories to one 'virtual' path, for
reading mods. However, writing data is problematic: which path to
choose?
The only viable solution is to use a path relative to the highest
priority directory encountered in the VFS path, or write paths could be
'hijacked' by lower-priority mods.
This fixes these issues by:
- Adding a new lookup mode ('Real-path') that explicitly picks the real
path relative to the highest-priority subdirectory in the VFS Path.
- Preventing overwriting a real directory with a lower priority one in
general.
- Revert c0c8132dd4's GetRealPath change, re-introducing the function as
GetOriginalPath.
This also cleans up some duplication that led to empty mod folders in
the user mod path, and cleans up loading the 'user' mod.
It also makes it explicit that a directory must be passed to Mount().
Note that the new 'realpath' lookup can still be somewhat complex with
many mount points at various hierarchy levels, but it is at least
predictable/deterministic without having to be careful about populating
order.

The JS-side counterparts of C++ objects are now Proxy objects, in
anticipation of SM60 changes that remove the get/set hooks entirely.
This makes semantic sense too as they are essentially phantom wrappers
around the C++ objects, with no proper JS representation.
By using different proxy handlers for different GUI object types, we can
further fix issues encountered in D2136 by defining the relevant
functions only on objects that should have them.
The main complexity with proxy handlers is that Spidermonkey assumes in
several places that they are static and data-less, so they cannot be
used directly to hold data. This diff works around that issue by storing
per-script-interface data in the CGui directly.
Further API changes in SM60 make this slightly cleaner.

easier to distribute the program as a result. Expect a negligible size
increase in the binary size (offset somewhat by no longer needing to

As part of the SM45->52 migration, a ScriptInterface becomes a wrapper
around a JSCompartment, not a JSContext, thus we ought to store private
data for the compartment and not the context.
This is a mass rename of CxPrivate to CmptPrivate to match that before
the actual changes.

This was SVN commit r24177.
JSAutoRequest is required before calling into most JSAPI methods, for GC
reasons.
Calling it is required and fragile as one must not forget.
Further, SM52 and later make manipulating JSContext* dangerous as that
can cross Compartment(Realm in SM68) barriers (and ScriptInterface now
matches a Compartment).
The solution to both problems is to avoid using JSContext* in 0 A.D.
itself. To achieve this, a Request class is introduced, and must be used
to access a JSContext* from a scriptInterface. Further, Request is
passed to other ScriptInterface functions isntead of JSContext*, making
it obvious that the caller has already called it, reducing errors and
redundant JSAutoRequest calls.
Only JSNative functions now get a naked JSContext* without protection,
but the likelihood of forgetting a request is lower since many
ScriptInterface functions now expect it.
JSContext* is directly passed to JSAPI functions only.

This was SVN commit r24170.
When serialising JS objects, we keep track of any encountered object,
and serialize it only once. Any further serialisation instead stores an
ID referring to the original object (essentially an opaque pointer).
The trouble of course is to have a unique, persistent identifier for
such an object.
svn uses an ObjectIDCache, essentially a "JS Object -> ID" map (which
internally is essentially a "JS heap pointer -> ID" map).
JS, since ES15, includes a "Symbol" primitive type, which is a unique,
immutable identifier. They are also not iterable by for..in or
GetOwnPropertyName or related.
This means they can be used to store the tag directly on the object
(since it's impossible overwrite a user property).
Thanks to this, we can forgo ObjectIDCache in the serializers, and since
following D2897 it becomes unused, we can delete it, along with the
Finalization code it used.

If one mod is not signed or broken in any other way, mod.io downloader
fails and does not display any mod.
The problem with unsigned mod is that its metadata are empty.
That means one cannot break mod io downloader with mods having invalid

This lets it support the JSClass syntax, introduced for components in
5fb88172a2/D2492, which required a workaround before.
As cleanup, remove the prefix logic which was too specific to be in
ScriptInterface, and use an upstream-compatible API that also does more
of what we want.

This breaked a SM assertion, which was only caught in debug mode. It
could have led to subtle bugs during the compilation of JS scripts.
Still set the flag to its default value, because SM devs wanted to
change the default in the future.
