||
| > 2023/07/30 - Prerelease | ||
| This initial prerelease proposes a programmable Nginx module for executing Wasm | ||
| bytecode in Nginx and/or OpenResty: ngx_wasm_module. | ||
|
|
||
| The module must be linked to one of three supported WebAssembly runtimes: | ||
| Wasmtime, Wasmer, or V8. | ||
|
|
||
| Along with a programmable "Nginx Wasm VM" interface, this release also comes with | ||
| initial support for Proxy-Wasm filters (i.e. Proxy-Wasm Host environment), and a | ||
| number of surrounding libraries for peripheral or optional usage of the module. | ||
| All releases are documented in a "git book" hosted in the project's repository: | ||
| the [user | ||
| documentation](https://github.com/Kong/ngx_wasm_module/tree/main/docs). **When | ||
| consulting any file under this location, make sure to checkout the proper | ||
| revision tag for your release.** | ||
|
|
||
| ### Documentation | ||
|
|
||
| This release is documented in a "git book" that is hosted in the same repository | ||
| as the [user documentation](https://github.com/Kong/ngx_wasm_module/tree/prerelease-0.1.0/docs). | ||
|
|
||
| To install the module, consult [INSTALL.md](https://github.com/Kong/ngx_wasm_module/tree/prerelease-0.1.0/docs/INSTALL.md). | ||
| To install the module, consult | ||
| [INSTALL.md](https://github.com/Kong/ngx_wasm_module/tree/main/docs/INSTALL.md). | ||
|
|
||
| For Nginx users, the module can be used through `nginx.conf` directives, | ||
| documented in [DIRECTIVES.md](https://github.com/Kong/ngx_wasm_module/tree/prerelease-0.1.0/docs/DIRECTIVES.md). | ||
| documented in | ||
| [DIRECTIVES.md](https://github.com/Kong/ngx_wasm_module/tree/main/docs/DIRECTIVES.md). | ||
|
|
||
| OpenResty users can also expect to use ngx_wasm_module via the bundled LuaJIT | ||
| FFI binding, for which no documentation exists at the moment. | ||
|
|
||
| Proxy-Wasm filters authors will be interested in [PROXY_WASM.md](https://github.com/Kong/ngx_wasm_module/tree/prerelease-0.1.0/docs/PROXY_WASM.md) | ||
| Proxy-Wasm filters authors will be interested in | ||
| [PROXY_WASM.md](https://github.com/Kong/ngx_wasm_module/tree/main/docs/PROXY_WASM.md) | ||
| for a primer on Proxy-Wasm in ngx_wasm_module and a picture of the supported | ||
| Host ABI. | ||
|
|
||
| As for Nginx developers, the module can also be used to write other modules; the | ||
| best resource for that sort of information would be [DEVELOPER.md](https://github.com/Kong/ngx_wasm_module/tree/prerelease-0.1.0/docs/DEVELOPER.md). | ||

| ## 0.1.1 | ||
|
|
||
| > 2023/10/06 - Prerelease | ||
| > | ||
| > [Documentation](https://github.com/Kong/ngx_wasm_module/tree/prerelease-0.1.1/docs) | ||
| > | [Release assets](https://github.com/Kong/ngx_wasm_module/releases/tag/prerelease-0.1.1) | ||
| This prerelease contains fixes and a few minor improvements atop the initial | ||
| prerelease. | ||
|
|
||
| An important fix contained in this changeset is the resolution of a memory leak | ||
| that occurred when using Proxy-Wasm filter chains with the `none` isolation | ||
| mode. | ||
|
|
||
| #### Changes | ||
|
|
||
| > [0.1.0...0.1.1](https://github.com/Kong/ngx_wasm_module/compare/prerelease-0.1.0...prerelease-0.1.1) | ||
| - Proxy-Wasm | ||
| - Feature: add support for Unix domain sockets in HTTP dispatch calls. | ||
| - Bugfix: resolve a memory leak when using low isolation modes (i.e. | ||
| `none`). | ||
| - Bugfix: ensure the whole filter chain is executed in response steps. | ||
| - Bugfix: ensure the rest of the filter chain is executed after HTTP | ||
| dispatch responses. | ||
| - Bugfix: prevent a crash when reading maps from non-HTTP contexts. | ||
| - Bugfix: prevent HTTP dispatch calls from having multiple Host and | ||
| Connection headers. | ||
| - Misc: improve the clarity of some filter chain error messages. | ||
| - Wasmtime | ||
| - Feature: set `RUST_BACKTRACE=full` when `backtraces` is enabled. | ||
| - Bugfix: allow overriding the `WASMTIME_BACKTRACE_DETAILS` environment | ||
| variable. | ||
| - Misc: compatibility with Wasmtime 12.0.2 which resolves the known issue | ||
| documented in [0.1.0]. | ||
| - Perf: avoid heap allocations in most host function calls. | ||
| - Wasmer | ||
| - Feature: set `RUST_BACKTRACE=full` when `backtraces` is enabled. | ||
| - LuaJIT FFI | ||
| - Bugfix: prevent a crash when the stream subsystem is in use. | ||
| - Bugfix: resolve a memory leak when using `get/set_property` in | ||
| `init_worker_by_lua`. | ||
| - Lua bridge | ||
| - Bugfix: avoid a use-after-free with the latest OpenResty 1.21.4.2 release. | ||
| - Misc | ||
| - Bugfix: fix compilation errors with newer clang and gcc versions. | ||
|

||
| #### Dependencies | ||
|
|
||
| This release is tested with the following Nginx/OpenResty versions and dependencies: | ||
|
|
||
| Name | Version | Notes | ||
| ---------:|:---------------:|:-------------------------------------------------- | ||
| Nginx | [1.25.2](https://nginx.org/en/download.html) | | ||
| OpenResty | [1.21.4.2](https://openresty.org/en/download.html) | | ||
| OpenSSL | [3.1.3](https://www.openssl.org/source/) | | ||
| Wasmtime | [12.0.2](https://github.com/bytecodealliance/wasmtime/releases) | | ||
| Wasmer | [3.1.1](https://github.com/wasmerio/wasmer/releases/) | | ||
| V8 | [11.4.183.23](https://github.com/Kong/ngx_wasm_runtimes/releases/) | Built by [Kong/ngx_wasm_runtimes] for convenience. | ||
|
|
||
| #### Components | ||
|
|
||
| Same as [0.1.0]. | ||
|
|
||
| #### Known Issues | ||
|
|
||
| - When using Wasmtime, reloading Nginx with `SIGHUP` seems to leave workers | ||
| susceptible to crashes on Wasm instance exceptions such as `SIGFPE`. See | ||
| [#418](https://github.com/Kong/ngx_wasm_module/issues/418). | ||
| - Proxy-Wasm filter chains issuing HTTP dispatch calls during `on_request_body` | ||
| will cause inconsistencies in the filter chain execution. | ||
