./devel/hs-atomic-write, Atomically write to a file

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

Branch: CURRENT, Version: 0.2.0.7nb5, Package name: hs-atomic-write-0.2.0.7nb5, Maintainer: pkgsrc-users

Atomically write to a file on POSIX-compliant systems while preserving
permissions.

On most Unix systems, mv is an atomic operation. This makes it simple to
write to a file atomically just by using the mv operation. However, this
will destroy the permissions on the original file. This library does the
following to preserve permissions while atomically writing to a file:

* If an original file exists, take those permissions and apply them to the
temp file before mving the file into place.

* If the original file does not exist, create a following with default
permissions (based on the currently-active umask).

This way, when the file is mv'ed into place, the permissions will be the
ones held by the original file.

devel/hs-atomic-write: Fix build with GHC 9.8

This breaks build with the currently default GHC 9.6. Please bear with me
until I switch the default compiler.
