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.

stdio: don't assume gets any more
|
|
|
|
Gnulib intentionally does not have a gets module, and now that C11
|
|
and glibc have dropped it, we should be more proactive about warning
|
|
any user on a platform that still has a declaration of this dangerous
|
|
interface.
|
|
|
|
* m4/stdio_h.m4 (gl_STDIO_H, gl_STDIO_H_DEFAULTS): Drop gets
|
|
support.
|
|
* modules/stdio (Makefile.am): Likewise.
|
|
* lib/stdio-read.c (gets): Likewise.
|
|
* tests/test-stdio-c++.cc: Likewise.
|
|
* m4/warn-on-use.m4 (gl_WARN_ON_USE_PREPARE): Fix comment.
|
|
* lib/stdio.in.h (gets): Make warning occur in more places.
|
|
* doc/posix-functions/gets.texi (gets): Update documentation.

However, we believe that sprintf can be used safely, and is more

efficient than snprintf in those safe cases; and as proof of our

belief, we use sprintf in several gnulib modules. So this header
