`JSNatives` passed to SpiderMonkey must not throw exceptions. Most
callbacks are wrapped in `ScriptFunction::ToJSNative`.
This commit adds exception handling to `ScriptFunction::ToJSNative` so
that exceptions thrown in the wrapped callbacks are catched and rethrown
as JavaScript `Error`s.

During hotloading the `ScriptRequest` was constructed from a
`JSContext*`. That requires that already an other `ScriptRequest` is
active. Which isn't always the case.
Now The `ScriptRequest` is constructed from a `ScriptInterface&`.
Storing a `ScriptInterface&` in the `ModuleLoader::Result` allows to
remove the `m_Result` as it is retrieved from the `ScriptInterface`.
This commit introduces support for std::optional<T> in
Script::FromJSVal. When a JavaScript value is undefined or null, the
resulting optional is set to std::nullopt; otherwise, the value is
converted and wrapped.
This change allows components to cleanly handle optional script values
without needing manual null checks or exception handling in C++.
As a direct application of this feature, the Identity component now uses
std::optional<std::wstring> for the return value of GetCiv(). This
resolves a bug where formation templates (e.g., those inheriting from
template_formation.xml) do not explicitly define a civ. After commit
03f7903fec, the code assumed GetCiv() would always return a valid
string, leading to undefined behavior when it was missing.
With this update:
- GetCiv() returning undefined results in an empty optional.
- The Identity component defaults to an empty civilization string ("")
when the civ is not defined.
- This avoids crashes or actor parsing errors for civ-less templates and
improves robustness in script-C++ interaction.
Closes: #8107Fixes: #8091
Previously, if a JavaScript function returned a value that failed to
convert to the requested C++ type (e.g., from JS undefined to
std::wstring), the ScriptInterface would fail silently, making debugging
difficult.
This commit improves the error reporting in the script system by logging
the name of the JavaScript function being called when a type conversion
failure occurs. This makes it easier to trace and fix issues arising
from script-side inconsistencies or missing return values.
The improved logging is particularly useful for debugging errors such as
undefined civ values from GetCiv() when used via m_Script.Call<T>().
Add a way to tell whether `ReloadChangedFiles` actually catched events
by returning `INFO::SKIPPED` when it didn't.
Unlike GUI apps, you have to explicitely tell macOS to punp events in
console apps thus add a loop in the tests.
Not all modules should be able to load all other modules. A predicate
function can to be passed to the `ScriptInterface`. That function
returns whether the module is allowed to loat the module. If no
predicate is passed in no modules can be loaded through that
`ScriptInterface`.
- With modules JavaScript code can be split up into multiple files. We
already implemented such a mechanism (`Engine.LoadLibrary`) in
multiple parts of the engine. The advantage of using modules is
that it's standart (JS-devs are familiar with it) and it doesn't
has to be implemented multiple times.
Note that `Engine.LoadLibrary` loads all files in a directory
while the new `import` only loads one file.
- With modules seemingly global variables are local to that
script/module. We already implemented such a mechanism
(`ScriptInterface::LoadScript`).
As noted on #7979, we run into OOMs since commit af32d386b9. The reason is that the default incremental GC budget is unlimited, which actually doesn't perform incremental GCs. Our settings can lead to situation where the incremental GCs don't actually sweep, thus not freeing memory.
SM has a mechanism to avoid OOM anyways with LAST_DITCH GCs, but by default these can only occur ever 30 seconds. Turn this off.
Reported by: langbart
Shrinking GCs dump the JITted code, which leads to redundant recompilations, lowers performance, and makes profiling JS more difficult.
They may still happen if the runtime is at risk of OOM.
SpiderMonkey 98 introduced a size heuristic for the nursery GC region
(https://phabricator.services.mozilla.com/D136637). As this heuristic
uses a wall-clock time duration, it results in a severe performance
regression on slower systems for our use case.
This commit adds a workaround to turn off that heuristic, by telling
SpiderMonkey that a "page load" (something which doesn't have a meaning
in the context of pyrogenesis) is in progress, as that heuristic is
disabled for page loads.

The context option enabling strict mode was removed in sm-117 [1]
requiring to use the compiler option for the same purpose instead.

- 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
version 57. Turning these off is a very large speedup, around 10-20%
wall time (on my computer) depending on the map and the situation.
For the most part, from profiling on my machine, this is from memory
fences after JIT -> C++ calls. 0 A.D. does a lot of these.
The SPECTRE class of attack is a timing attack based on speculative
execution to leak sensitive information, and it seems extraordinarily
unlikely that something like this could be successfully mounted using 0
A.D.
