This can be tuned by using `android_cleaner = true`, +// or `android = true` in the [`kotlin` section of the `uniffi.toml` file](https://mozilla.github.io/uniffi-rs/kotlin/configuration.html). +// +// If we try to implement this with mutual exclusion on access to the handle, there is the +// possibility of a race between a method call and a concurrent call to `destroy`: +// +// * Thread A starts a method call, reads the value of the handle, but is interrupted +// before it can pass the handle over the FFI to Rust. +// * Thread B calls `destroy` and frees the underlying Rust struct. +// * Thread A resumes, passing the already-read handle value to Rust and triggering +// a use-after-free. +// +// One possible solution would be to use a `ReadWriteLock`, with each method call taking +// a read lock (and thus allowed to run concurrently) and the special `destroy` method +// taking a write lock (and thus blocking on live method calls). However, we aim not to +// generate methods with any hidden blocking semantics, and a `destroy` method that might +// block if called incorrectly seems to meet that bar. +// +// So, we achieve our goals by giving each instance an associated `AtomicLong` counter to track +// the number of in-flight method calls, and an `AtomicBoolean` flag to indicate whether `destroy` +// has been called. These are updated according to the following rules: +// +// * The initial value of the counter is 1, indicating a live object with no in-flight calls. +// The initial value for the flag is false. +// +// * At the start of each method call, we atomically check the counter. +// If it is 0 then the underlying Rust struct has already been destroyed and the call is aborted. +// If it is nonzero them we atomically increment it by 1 and proceed with the method call. +// +// * At the end of each method call, we atomically decrement and check the counter. +// If it has reached zero then we destroy the underlying Rust struct. +// +// * When `destroy` is called, we atomically flip the flag from false to true. +// If the flag was already true we silently fail. +// Otherwise we atomically decrement and check the counter. +// If it has reached zero then we destroy the underlying Rust struct. +// +// Astute readers may observe that this all sounds very similar to the way that Rust's `Arc` works, +// and indeed it is, with the addition of a flag to guard against multiple calls to `destroy`. +// +// The overall effect is that the underlying Rust struct is destroyed only when `destroy` has been +// called *and* all in-flight method calls have completed, avoiding violating any of the expectations +// of the underlying Rust code. +// +// This makes a cleaner a better alternative to _not_ calling `destroy()` as +// and when the object is finished with, but the abstraction is not perfect: if the Rust object's `drop` +// method is slow, and/or there are many objects to cleanup, and it's on a low end Android device, then the cleaner +// thread may be starved, and the app will leak memory. +// +// In this case, `destroy`ing manually may be a better solution. +// +// The cleaner can live side by side with the manual calling of `destroy`. In the order of responsiveness, uniffi objects +// with Rust peers are reclaimed: +// +// 1. By calling the `destroy` method of the object, which calls `rustObject.free()`. If that doesn't happen: +// 2. When the object becomes unreachable, AND the Cleaner thread gets to call `rustObject.free()`. If the thread is starved then: +// 3. The memory is reclaimed when the process terminates. +// +// [1] https://stackoverflow.com/questions/24376768/can-java-finalize-an-object-when-it-is-still-in-scope/24380219 +// + + +/** + * Unified access point for bundles from both the builtin and remote sources. + * + * The remote source takes precedence over the builtin source when both contain + * a bundle with the same name. + */ +public interface BundleSourceInterface { + + /** + * Loads the full builtin bundle for `bundle_name` at `version`, bypassing the + * remote source and version resolution. + */ + suspend fun `fetchBuiltinBundle`(`bundleName`: kotlin.String, `version`: kotlin.String): Bundle + + /** + * Loads the full bundle (header + index + data) for `bundle_name`. + */ + suspend fun `fetchBundle`(`bundleName`: kotlin.String): Bundle + + /** + * Loads only the header and index for `bundle_name`, skipping the data section. + * The returned descriptor does not support [`BundleDescriptor::index`]; use + * [`fetch`](BundleSource::fetch_bundle) when entry data is needed. + */ + suspend fun `fetchDescriptor`(`bundleName`: kotlin.String): BundleDescriptor + + /** + * Loads the full remote bundle for `bundle_name` at `version`, bypassing the + * builtin source and version resolution. */ suspend fun `fetchRemoteBundle`(`bundleName`: kotlin.String, `version`: kotlin.String): Bundle @@ -2865,7 +3597,7 @@ open class BundleSource: Disposable, AutoCloseable, BundleSourceInterface } constructor(`config`: BundleSourceConfig) : this(UniffiWithHandle, -

This is not a panacea, and client code should be aware that +// 1. the thread may starve if some there are objects that have poorly performing +// `drop` methods or do significant work in their `drop` methods. +// 2. the thread is shared across the whole library. This can be tuned by using `android_cleaner = true`, +// or `android = true` in the [`kotlin` section of the `uniffi.toml` file](https://mozilla.github.io/uniffi-rs/kotlin/configuration.html). +// +// If we try to implement this with mutual exclusion on access to the handle, there is the +// possibility of a race between a method call and a concurrent call to `destroy`: +// +// * Thread A starts a method call, reads the value of the handle, but is interrupted +// before it can pass the handle over the FFI to Rust. +// * Thread B calls `destroy` and frees the underlying Rust struct. +// * Thread A resumes, passing the already-read handle value to Rust and triggering +// a use-after-free. +// +// One possible solution would be to use a `ReadWriteLock`, with each method call taking +// a read lock (and thus allowed to run concurrently) and the special `destroy` method +// taking a write lock (and thus blocking on live method calls). However, we aim not to +// generate methods with any hidden blocking semantics, and a `destroy` method that might +// block if called incorrectly seems to meet that bar. +// +// So, we achieve our goals by giving each instance an associated `AtomicLong` counter to track +// the number of in-flight method calls, and an `AtomicBoolean` flag to indicate whether `destroy` +// has been called. These are updated according to the following rules: +// +// * The initial value of the counter is 1, indicating a live object with no in-flight calls. +// The initial value for the flag is false. +// +// * At the start of each method call, we atomically check the counter. +// If it is 0 then the underlying Rust struct has already been destroyed and the call is aborted. +// If it is nonzero them we atomically increment it by 1 and proceed with the method call. +// +// * At the end of each method call, we atomically decrement and check the counter. +// If it has reached zero then we destroy the underlying Rust struct. +// +// * When `destroy` is called, we atomically flip the flag from false to true. +// If the flag was already true we silently fail. +// Otherwise we atomically decrement and check the counter. +// If it has reached zero then we destroy the underlying Rust struct. +// +// Astute readers may observe that this all sounds very similar to the way that Rust's `Arc` works, +// and indeed it is, with the addition of a flag to guard against multiple calls to `destroy`. +// +// The overall effect is that the underlying Rust struct is destroyed only when `destroy` has been +// called *and* all in-flight method calls have completed, avoiding violating any of the expectations +// of the underlying Rust code. +// +// This makes a cleaner a better alternative to _not_ calling `destroy()` as +// and when the object is finished with, but the abstraction is not perfect: if the Rust object's `drop` +// method is slow, and/or there are many objects to cleanup, and it's on a low end Android device, then the cleaner +// thread may be starved, and the app will leak memory. +// +// In this case, `destroy`ing manually may be a better solution. +// +// The cleaner can live side by side with the manual calling of `destroy`. In the order of responsiveness, uniffi objects +// with Rust peers are reclaimed: +// +// 1. By calling the `destroy` method of the object, which calls `rustObject.free()`. If that doesn't happen: +// 2. When the object becomes unreachable, AND the Cleaner thread gets to call `rustObject.free()`. If the thread is starved then: +// 3.
