To build the bindings locally, the bindings require some additional work which is still making its
way upstream, for now it should be built against the
-[rust-lightning 2021-03-java-bindings-base branch on git.bitcoin.ninja](https://git.bitcoin.ninja/?p=rust-lightning;a=shortlog;h=refs/heads/2021-03-java-bindings-base).
+[rust-lightning 2022-10-112-java-bindings branch on git.bitcoin.ninja](https://git.bitcoin.ninja/?p=rust-lightning;a=shortlog;h=refs/heads/2022-10-112-java-bindings).
Check that branch out locally as well as [ldk-c-bindings](https://github.com/lightningdevkit/ldk-c-bindings)
and run the `genbindings.sh` script in ldk-c-bindings to build the required binaries. Thereafter,
in this repo, run the `genbindings.sh` script with the first argument pointing to the ldk-c-bindings
When running a program linking against the library in debug mode, LD_PRELOAD should likely include
the relevant `libclang_rt.asan-platform.so` path.
+Note that building with address sanitizer is only supported on MacOS with upstream clang (ie where
+the LLVM version in use matches the LLVM version against which rustc was built), not with Apple clang.
+Builds with Apple clang will work fine, but largely only be useful in a release context.
+To build on Mac with address sanitizer, you will need to run `ldk-c-bindings`' `genbindings.sh`
+script with upstream clang in your PATH and likely replace your $JAVA_HOME/bin/java with a simple
+wrapper which calls java after an export like:
+`export DYLD_INSERT_LIBRARIES=/path/to/upstream/llvm/lib/clang/12.0.0/lib/darwin/libclang_rt.asan_osx_dynamic.dylib`
+
+To build for Apple M1 (ie aarch64-apple-darwin), you probably want something like
+`CC="clang --target=aarch64-apple-darwin" LDK_TARGET=aarch64-apple-darwin LDK_TARGET_CPU=generic ./genbindings.sh ...`

Status
======
-The TypeScript Bindings are still in early development and generated code contains syntax errors.
+## Java
While the underlying library and C bindings are relatively mature, the Java bindings should be
-considered alpha quality and some memory management issues may still appear. Specifically, because
-the Java bindings map between two very different memory models - Rust's strict ownership model and
-Java's reference cloning and garbage collection - a lot of work occurs in the background to keep
-the Java GC informed of Rust ownership semantics.
-
-There are some known memory leaks, which are relatively modest in the existing test suite (around
-1MB for 128 node constructions and 64 full channel constructions and payments sent), but which may
-be less moderate in certain usages. The debug-mode build includes memory leak tracking and will
-print all loose objects when the program exists, though without calls to
-`System.gc(); System.runFinalization();` immediately before exit there will likely be many false
-positives. While it will require some complicated usage, there are likely some use-after-free or
-unkonwn-free bugs remaining. The debug-mode build links LLVM address sanitizer and will print
-diagnostic information in case of such issues.

+## TypeScript
+
+The TypeScript bindings are functionally complete, but should be considered early alpha quality.
+Some functions may error spuriously due to oversights or missing implementations.
+
+The TypeScript bindings require modern web standards, including support for `FinalizationRegistry`
+and `WeakRef` (Chrome 84, Firefox 79, Safari 14.1/iOS 14.5 and Node 14.6) and WASM BigInt support
+(Chrome 85, Firefox 78, Safari 14.1/iOS 14.5, and Node 15.0).
+
+For users of Node.JS environments you may wish to use the `lightningdevkit-node-net` package as
+well to implement the required network handling to bridge the `lightningdevkit` package's
+`SocketDescriptor` interface to Node.JS TCP Sockets. For those wishing to run a lightning node in
+the browser you will need to provide your own bridge from `SocketDescriptor` to a WebSocket proxy.
