./devel/hs-atomic-primops, Safe approach to CAS and other atomic ops in Haskell

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 0.8.7nb1, Package name: hs-atomic-primops-0.8.7nb1, Maintainer: pkgsrc-users

After GHC 7.4 a new casMutVar# primop became available, but it's difficult
to use safely, because pointer equality is a highly unstable property in
Haskell. This library provides a safer method based on the concept of
Tickets.

Also, this library uses the "foreign primop" capability of GHC to add
access to other variants that may be of interest, specifically, compare and
swap inside an array.

Note that as of GHC 7.8, the relevant primops have been included in GHC
itself. This library is engineered to work pre- and post-GHC-7.8, while
exposing the same interface.

Log message:
devel/hs-atomic-primops: Update to 0.8.7

0.8.7 [2024.04.20]
    Fix typos in the foreign imports introduced in atomic-primops-0.8.5 and
    atomic-primops-0.8.6, which would lead to linker errors when building
    executables with GHC 9.10.

0.8.6 [2024.04.16]
    Use prim, not ccall, for the foreign imports used when building the
    library with GHC 9.10 or later. This fixes a GHC 9.10-specific build
    issue.

0.8.5 [2024.02.17]
    Allow building with GHC 9.10.
