 # [Squoosh]!

-[Squoosh] is an image compression web app that reduces image sizes through numerous formats.
+[Squoosh] is an image compression web app that allows you to dive into the advanced options provided
+by various image compressors.

-# API & CLI
+# CLI

-Squoosh has [an API](https://github.com/GoogleChromeLabs/squoosh/tree/dev/libsquoosh) and [a CLI](https://github.com/GoogleChromeLabs/squoosh/tree/dev/cli) to compress many images at once.
+[Squoosh now has a CLI](https://github.com/GoogleChromeLabs/squoosh/tree/dev/cli) that allows you to compress many images at once.

 # Privacy

-Squoosh does not send your image to a server. All image compression processes locally.
+Google Analytics is used to record the following:

-However, Squoosh utilizes Google Analytics to collect the following:
+- [Basic visit data](https://support.google.com/analytics/answer/6004245?ref_topic=2919631).
+- Before and after image size once an image is downloaded. These values are rounded to the nearest
+  kilobyte.
+- If install is available, when Squoosh is installed, and what method was used to install Squoosh.

- [Basic visitor data](https://support.google.com/analytics/answer/6004245?ref_topic=2919631).
- The before and after image size value.
- If Squoosh PWA, the type of Squoosh installation.
- If Squoosh PWA, the installation time and date.
+Image compression is handled locally; no additional data is sent to the server.

-# Developing
+# Building locally

-To develop for Squoosh:
+Clone the repo, and:

-1. Clone the repository
-1. To install node packages, run:
-   ```sh
-   npm install
-   ```
-1. Then build the app by running:
-   ```sh
-   npm run build
-   ```
-1. After building, start the development server by running:
-   ```sh
-   npm run dev
-   ```
+```sh
+npm install
+npm run build
+```

-# Contributing
+You can run the development server with:

-# Project no longer maintained
-
-Unfortunately, due to a few people leaving the team, and staffing issues resulting from the current economic climate (ugh), this package is no longer actively maintained. I know that sucks, but there simply isn't the time & people to work on this. If anyone from the community wants to fork it, you have my blessing. The [squoosh.app](https://squoosh.app) will continue to be supported and improved.

 # Squoosh CLI

 Squoosh CLI is an _experimental_ way to run all the codecs you know from the [Squoosh] web app on your command line using WebAssembly. The Squoosh CLI uses a worker pool to parallelize processing images. This way you can apply the same codec to many images at once.

+//! This is a module that provides `malloc` and `free` for `libdeflate`.
+//! These implementations are compatible with the standard signatures
+//! but use Rust allocator instead of including libc one as well.
+//!
+//! Rust allocator APIs requires passing size and alignment to the
+//! `dealloc` function. This is different from C API, which only
+//! expects a pointer in `free` and expects allocators to take care of
+//! storing any necessary information elsewhere.
+//!
+//! In order to simulate C API, we allocate a `size_and_data_ptr`
+//! of size `sizeof(usize) + size` where `size` is the requested number
+//! of bytes. Then, we store `size` at the beginning of the allocated
+//! chunk (within those `sizeof(usize)` bytes) and return
+//! `data_ptr = size_and_data_ptr + sizeof(usize)` to the calleer:
+//!
+//! [`size`][...actual data]
+//! -^------------------ `size_and_data_ptr`
+//! ---------^---------- `data_ptr`
+//!
+//! Then, in `free`, the caller gives us `data_ptr`. We can subtract
+//! `sizeof(usize)` back and get the original `size_and_data_ptr`.
+//! At this point we can read `size` back and call the Rust `dealloc`
+//! for the whole allocated chunk.
+//!
+//! I've raised an upstream issue to hopefully make this easier in
+//! future: https://github.com/ebiggers/libdeflate/issues/62

+//
+// rayon::ThreadPoolBuilder (used below) executes spawn handler to populate the worker pool,
+// and then blocks the current thread until each worker unblocks its (opaque) lock.
+//
+// Normally, we could use postMessage directly inside the spawn handler to
+// post module + memory + threadPtr to each worker, and the block the current thread.
+//
+// However, that bug means that postMessage is currently delayed until the next event loop,
+// which will never spin since we block the current thread, and so the other workers will
+// never be able to unblock us.
+//
+// To work around this problem, we:
+// 1) Expose `worker_initializer` that returns module + memory pair (without threadPtr)
+//    that workers can be initialised with to become native threads.
+//    JavaScript can postMessage this pair in advance, and asynchronously wait for workers
+//    to acknowledge the receipt.
+// 2) Create a global communication channel on the Rust side using crossbeam.
+//    It will be used to send threadPtr to the pre-initialised workers
+//    instead of postMessage.
+// 3) Provide a separate `start_main_thread` that expects all workers to be ready,
+//    and just uses the provided channel to send `threadPtr`s using the
+//    shared memory and blocks the current thread until they're all grabbed.
+// 4) Provide a `worker_initializer` that is expected to be invoked from various workers,
+//    reads one `threadPtr` from the shared channel and starts running it.
