it's complicated and hard to use in practice, because it's not obvious
if a piece of code is running under another fiber or not, so
`Fiber.spawn` might fail because it has no parent.
So in practice we've been using `Fiber.spawn_top`… which has no
interest over just using `Fut.spawn`.
there's a race condition where, by the time we schedule the
main fiber in `lwt_main`, the event loop is already asleep (maybe
from a previous run). We make sure to wake the loop up.
* feat: depend on picos, use picos.exn_bt
* refactor: remove dla
* non optional dependency on thread-local-storage
it's a dep of picos anyway
* wip: use picos computations
* disable t_fib1 test, way too flaky
* feat `fut`: wrap picos computations
* detail in fut
* gitignore
* refactor core: use picos for schedulers; add Worker_loop_
we factor most of the thread workers' logic in `Worker_loop_`,
which is now shared between Ws_pool and Fifo_pool
* github actions
* feat fut: add `on_result_ignore`
* details
* wip: port to picos
* test: wip porting tests
* fix fut: trigger failing to attach doesn't signal it
* fix pool: only return No_more_tasks when local and global q empty
* format
* chore: fix CI by installing picos first
* more CI
* test: re-enable t_fib1 but with a single core fifo pool
it should be deterministic now!
* fixes after reviews
* bump minimal OCaml version to 4.13
* use `exn_bt`, not `picos.exn_bt`
* feat: optional dep on hmap, for inheritable FLS data
* format
* chore: depend on picos explicitly
* feat: move hmap-fls to Fiber.Fls
* change API for local FLS hmap
* refactor: move optional hmap FLS stuff into core/task_local_storage
* add Task_local_storage.remove_in_local_hmap
* chore: try to fix CI
* format
* chore: CI
* fix
* feat: add `Fls.with_in_local_hmap`
* chore: depend on hmap for tests
* fix test for FLS
use the inheritable keys
* chore: CI
* require OCaml 4.14 :/
* feat: add `moonpool.sync` with await-friendly abstractions
based on picos_sync
* fix: catch TLS.Not_set
* fix: `LS.get` shouldn't raise
* fix
* update to merged picos PR
* chore: CI
* fix dep
* feat: add `Event.of_fut`
* chore: CI
* remove dep on now defunct `exn_bt`
* feat: add moonpool-io
* chore: CI
* version constraint on moonpool-io
* add Event.Infix
* move to picos_io
