Arguments to logical shift are provided in bits, not bytes.

No tests added yet. It would be nice to test the Buf_write <-> Buf_read roundtrip. I'd be happy to add them, but am not sure where the best place would be.

tests/buf_write.md would be the best place for some tests. There are already tests for the reading side:

eio/tests/buf_reader.md

Lines 418 to 419 in 80f5352

# R.parse_string_exn R.LE.uint48 "\128\064\032\016\008\001" |> Printf.sprintf "0x%Lx";;
- : string = "0x10810204080"

Note: this code is from Faraday, so we should probably report it there too.

Thanks!

@talex5
Add Eio.Buf_read.uint8

This is to match `Buf_write.uint8`.

Buf_write: Fix BE.uint48 and LE.uint48.

Arguments to logical shift are provided in bits, not bytes.
Also, the BE version mixed up the 32-bit and 16-bit sizes.
Note: this bug also affects Faraday.

I added some round-trip tests, and also fixed a second bug in BE.uint48 😱

I also added Eio.Buf_read.uint8, which was missing.

Cool, thanks!

and also fixed a second bug in BE.uint48 😱

:) Interesting that this was never encountered in Faraday.

[new release] eio_main, eio_luv, eio_linux and eio (0.8)
4a75052 
CHANGES:

New features:

- Add `Eio.Net.run_server` (@bikallem @talex5 ocaml-multicore/eio#408).
  Runs an accept loop in one or more domains, with cancellation and graceful shutdown,
  and an optional maximum number of concurrent connections.

- Add `Buf_read.BE` and `LE` parsers (@Cjen1 ocaml-multicore/eio#399).
  Parse numbers in various binary formats.

- Add `Eio.Buf_read.uint8` (@talex5 ocaml-multicore/eio#418).

Performance:

- Make `Eio.Condition` lock-free (@talex5 ocaml-multicore/eio#397 ocaml-multicore/eio#381).
  In addition to being faster, this allows using conditions in signal handlers.

- Make `Eio.Semaphore` lock-free (@talex5 @polytypic ocaml-multicore/eio#398).

- Make `Eio.Stream` lock-free when the capacity is zero (@talex5 ocaml-multicore/eio#413 ocaml-multicore/eio#411).

- Make `Eio.Promise` lock-free (@talex5 ocaml-multicore/eio#401).

Bug fixes:

- eio_linux: call `Uring.submit` as needed (@talex5 @bikallem ocaml-multicore/eio#428).
  Previously, we could fail to submit a job promptly because the SQE queue was full.

- Fix luv signals (@haesbaert ocaml-multicore/eio#412).
  `libuv` automatically retries polling if it gets `EINTR`, without giving OCaml signal handlers a chance to run.

- eio_luv: fix some resource leaks (@talex5 @patricoferris ocaml-multicore/eio#421).

- eio_luv: fix "unavailable signal" error on Windows (@talex5 ocaml-multicore/eio#420, reported by @nojb).

- Fix `Buf_write.BE.uint48` and `LE.uint48` (@adatario ocaml-multicore/eio#418).

Documentation:

- Add example programs (@talex5 ocaml-multicore/eio#389).

- Update network examples to use `run_server` (@talex5 ocaml-multicore/eio#417).

- Add a warning to the tutorial about `Fiber.first` (@talex5 ocaml-multicore/eio#394).

- Clarify the epoch used for `Eio.Time.now` (@bikallem ocaml-multicore/eio#395).

- Describe `secure_random` as an infinite source (@patricoferris ocaml-multicore/eio#426).

- Update README for OCaml 5 release (@talex5 ocaml-multicore/eio#384 ocaml-multicore/eio#391 ocaml-multicore/eio#393).

Other changes:

- Delay setting `SIGPIPE` handler until the `run` function is called (@talex5 ocaml-multicore/eio#420).

- Remove debug-level logging (@talex5 ocaml-multicore/eio#403).

- eio-luv: improve `process.md` test (@smondet ocaml-multicore/eio#414).

- Update to Dune 3 (@talex5 ocaml-multicore/eio#410).

- Remove test dependency on Astring (@talex5 ocaml-multicore/eio#402 ocaml-multicore/eio#404).

- Simplify cancellation logic (@talex5 ocaml-multicore/eio#396).

- time: `Mtime.Spand.to_s` has been deprecated in mtime 2.0.0 (@bikallem ocaml-multicore/eio#385).
