Ah, I see you did use wasm exceptions!

I believe this is listed as "legacy" now, but the alternative proposal isn't supported in any runtimme at all so I'm good with using for now: https://webassembly.org/features/
Almost. I got a few notes from Janelia Scientific Computing Code Review this morning, so I have a few changes to make this evening. I also think a little more work is needed to catch the exceptions properly. I'm slightly unclear which exception handling feature I'm using on that chart. |

According to Mozilla, all major browsers have supported this since 2021 or 2022. https://developer.mozilla.org/en-US/docs/WebAssembly/JavaScript_interface/Exception#see_also

* Initial attempt at implementing Zstandard streaming decompression * Drop Node 16 due to exeptions support, bump setup-node to v4 * Add streaming decompression tests for streaming compression * Apply prettier * Add EXPORT_EXCEPTION_HANDLING_HELPERS * Code clean up * Fix typo in build.sh * Free decompression stream when throwing or exiting * Throw error if there is additional input data after decompressing frame * Run prettier on test/zstd.test.js * Update with recommendations from Janelia SciCompSoft code review * Update codecs/zstd/zstd_codec.cpp * Add changeset

Thanks! Released in v0.3.2 https://github.com/manzt/numcodecs.js/releases/tag/v0.3.2 |
The output of ZSTD_getFrameContentSize is now checked.
If ZSTD_CONTENTSIZE_UNKNOWN, then we try to stream decompress into a 1 MiB output buffer
that grows in
1 MiB128 KiB incrementsWe use
WebAssembly.Exceptionto report errors.Fix #46
