Subject: permits black to run in AWS Lambda: (#1141)
X-Git-Url: https://git.madduck.net/etc/vim.git/commitdiff_plain/c0a7582e3d4cc8bec3b7f5a6c52b36880dcb57d7?hp=c0a7582e3d4cc8bec3b7f5a6c52b36880dcb57d7

permits black to run in AWS Lambda: (#1141)

AWS Lambda and some other virtualized environment may not permit access
to /dev/shm on Linux and as such, trying to use ProcessPoolExecutor will
fail.

As using parallelism is only a 'nice to have' feature of black, if it fails
we gracefully fallback to a monoprocess implementation, which permits black
to finish normally.
