We are migrating packages that meet below requirements:
1. using `callPackage`
2. called path is a directory
3. overriding set is empty (`{ }`)
4. not containing path expressions other than relative path (to
makenixpkgs-vet happy)
5. not referenced by nix files outside of the directory, other
than`pkgs/top-level/all-packages.nix`
6. not referencing nix files outside of the directory
7. not referencing `default.nix` (since it's changed to `package.nix`)
8. `outPath` doesn't change after migration
The tool is here: https://github.com/Aleksanaa/by-name-migrate.

xjobs reads job descriptions line by line and executes them in parallel.
|
|
|
|
It limits the number of parallel executing jobs and starts new jobs when jobs finish.
|
|
|
|
Therefore, it combines the arguments from every input line with the utility
|
|
and arguments given on the command line.
|
|
If no utility is given as an argument to xjobs,
|
|
then the first argument on every job line will be used as utility.
|
|
To execute utility xjobs searches the directories given in the PATH environment variable
|
|
and uses the first file found in these directories.
|
|
|
|
xjobs is most useful on multi-processor/core machines when one needs to execute
|
|
several time consuming command several that could possibly be run in parallel.
|
|
With xjobs this can be achieved easily, and it is possible to limit the load
|
|
of the machine to a useful value.
|
|
|
|
It works similar to xargs, but starts several processes simultaneously
|
|
and gives only one line of arguments to each utility call.
