CHANGES: - Don't try to abusively fill the pipe to interrupt a domain Interrupting a domain involves writing to a pipe to interrupt the `select(2)` if it is running. The pipe has a limited memory, depending on the system, and if you ask to interrupt a domain too much, you end up blocking the `write`. This patch prevents writing to the pipe if it has not yet been read. (@dinosaure, robur-coop/miou#46) - Expose the Sequence module (@dinosaure, robur-coop/miou#47) - Be able to add a hook (effect free) into the scheduler It is possible to add a hook to the scheduler. If the user wants to execute a function to a domain each time the domain is busy with a task, they can do so. However, the effects are not managed in the passed function. (@dinosaure, robur-coop/miou#48) - Add `Miou.Lazy`, a domain-safe `Lazy` module like `Stdlib.Lazy` (@dinosaure, initially implemented by @polytypic, robur-coop/miou#49) - Raise an exception if the user uses syscalls (from `Miou_unix`) and `Miou.run` instead of `Miou_unix.run` If a user uses a suspend function offered by `Miou_unix` but does not use `Miou_unix.run`, the programme may block indefinitely. This patch prevents such an error by raising an exception if we want to add a suspension point and we haven't specified how to handle it (if we use `Miou.run` instead of `Miou_unix.run`). (@dinosaure, reported by @kit-ty-kate, robur-coop/miou#51) - Rename `Miou.set_signal` to `Miou.sys_signal` (@dinosaure, robur-coop/miou#50) - Improve `Miou_unix.{read,write}` (@kit-ty-kate, @dinosaure, robur-coop/miou#52, 2f552a6, robur-coop/miou#54) - Fix an issue related to the dom0 and pending tasks locked by mutexes Tasks may have been transmitted to dom0 while it was executing a task and before the `select(2)`. This patch resynchronises the pending tasks in dom0's TODO-list before making the `select(2)`: specifically to find out whether the `select(2)` can block indefinitely or not. This patch also cleans up the old states of the tables used by `Miou_unix` if it is used on an ongoing basis (as in the case of tests). (@dinosaure, robur-coop/miou#53) - Add `Miou.Domain.available` (@dinosaure, robur-coop/miou#53) - Fix a race condition (observed with TSan) when we wait the cancellation of a children This patch changes Miou's behaviour a little when waiting for a task to be cancelled and prevents invalid access to a value that does not belong to the current domain (and which can be modified by another domain). Thanks @OlivierNicole and @fabbing for their advice on using TSan. (@dinosaure, robur-coop/miou#56) - Update the layout of Miou to avoid conflicts with other packages (like `backoff`) (@dinosaure, reported by @patricoferris, robur-coop/miou#57) - OCaml 5.3 support (@kit-ty-kate, github#22) - Rename `Miou.call_cc` to `Miou.async` (@dinosaure, @kit-ty-kate, @Armael, github#23)

CHANGES: - Notice the domain if it needs to look into the shared heap if a task is ready to be transfered (@dinosaure, robur-coop/miou#41) - Don't use `Option.value` but `match .. with` to calculate the optional length for `Miou_unix.{read,write}` (@kit-ty-kate, robur-coop/miou#44) - Use `List.iter` instead of `Hashtbl.iter` for internal kept file-descriptors of `Miou_unix` (@dinosaure, robur-coop/miou#45) - Improve the documentation of `Miou_unix` about suspended syscalls (@dinosaure, @kit-ty-kate, robur-coop/miou#43) - Export `reraise` (@dinosaure, robur-coop/miou#46) - Fix an issue on the `dom0` and observe if some tasks must be transfered to it (@dinosaure, robur-coop/miou#48) - Fix documentation (@mbarbin, robur-coop/miou#47) - Fix the formatter (@mbarbin, robur-coop/miou#51) - Upgrade miou to `ocamlformat.0.27.0` (@mbarbin, robur-coop/miou#52) - Add `x-maintenance-intent` (@hannesm, robur-coop/miou#56) - Improve the documentation and some `odoc` warnings (@mbarbin, robur-coop/miou#53, robur-coop/miou#54)
