// ScriptStore manages versioned storage of both source scripts and prepared scripts. We intent to pass a ScriptSTore implementation
// directly into the JSI runtime from host. It will enable the following,
// 1. Pass richer data and metadata on the source scripts from host to JSI runtime without being constrained by the various layers in between.
// 2. Potential performance benefits as it will allow us to directly stream the source script and the prepared scripts from arbitrary storages and encoding without being constrained by intermediate layers.
// 3. Consolidate Source script versioning and storage logic into a single component.
// 4. Consolidate prepared script storage and persistance formats across platforms and aross JS-engines.
// 5. Allow co-existance of multiple Javascript engines, versions, strategies. (Some more work required to support multi-version)
// 6. Allow platform/storage/engine specific extensions for better performance.
* (*pedantry alert*)
Right-shifting a 32-bit value by 32 is, strictly, undefined behavior,
although every compiler worth its salt will understand that this is
just a funny way to generate 0. But anyways, this code causes VC++ to
emit warning C4293, which, per Office policy, may not be disabled.
* Fix C4244 warnings in MethodCall.cpp when compiling for x86, caused
by implicitly truncating `int64_t` values to `int` values.
* Remove a bunch of jsc files that should have been removed with 58
* more build fix
* Put back JSI JSCRuntime build switch
* Put back jni changes
* fix build
* Remove unneeded build logic
* Revert "Updating glog version to latest(0.3.5) which is the version RN is using now (#32)"
This reverts commit 4bfaca4eb5.
* Revert "Adding logging support on droid and logging failure message (#31)"
This reverts commit 7fd45d01b6.
Summary:
Fixes#23459. It is not legal to write the character array of a std::string, and can result in undefined behavior.

It's better to comment `DWITH_FBSYSTRACE` out in BUCK files instead of removing them from the code.

Summary:
This pull request makes two minor changes to `jsi.h`:
* Tweak the `JSI_EXPORT` macro to automatically set itself to an empty value if `_MSC_VER` is defined - like how was done by acoates-ms [here](8beb4bb58a/ReactCommon/cxxreact/JSBigString.h (L15-L21)).
* Tweak the call to constructor `Pointer(Runtime::PointerValue* ptr)` in the constructor for `PropNameID`. I am not sure why MSVC wasn't working with the original version, but it compiles after I tweak that.

Summary:
`Better` is a trivial collection of basic tools borrowed from other low-level general purpose libraries (like Folly, Abseil or Boost). The main goals of Better:
- Make the codebase more portable;
- Make the dependency list explicit (by decoupling it as a dependency list of Better);
- Make relying on modern C++ patterns and tools in code simple and easy.
- Make executing experiments with different dependencies easier.
As a first example usage, this diff replaces std::unordered_map with an efficient one from folly on the one of the hottest paths.

Summary:
Our long-term plan is to completely illuminate `jsi::Value`-to-`folly::dynamic` serialization step in prop parsing process improving performance and memory pressure. At the same time, we don't want to introduce a hard dependency in application code to JSI because it exposes direct access to VM and prevents parsing some data that come *NOT* from JSVM.
RawValue is an extremely light-weight (hopefully fully optimized-out) abstraction that provides limited JSON-like and C++-idiomatic interface.
The current particular implementation is still using `folly::dynamic` inside, but I have fully JSI-powered one which will replace the current one right after we figure out how to deal with folly::dynamic-specific callsites. Or we can implement RawValue in a hybrid manner if a code-size implication of that will be minimal.
