Meson doesn't set the right file-dependencies for D projects

[Cogitri]

Describe the bug It appears that meson doesn't set the right file-dependencies in one project. So if I change file test1.d is in shared lib a and test2.d depends on the imports from test1.d and is built against the shared liba, test2.d isn't rebuilt. This can cause really weird errors, e.g. when an Enum has changed in test1.d and the final switch (a construct which requires you to do an exhaustive match on an enum) in test2.d doesn't complain about the change (e.g. an addition of a new enum member) because it isn't rebuilt

To Reproduce I'll make a toy-project to demo this in a bit.

Expected behavior Meson should rebuild test2.d too.

system parameters Meson 0.54.0

To Reproduce:

• create files main.d:

  import a: print_in_a;
  
  void main(string[] args) {
      "test".print_in_a;
  }

  a.d:

  module a;
  
  import std.stdio: writeln;
  
  public void print_in_a(T)(T arg) {
      arg.writeln();
  }

  meson.build:

  project('Test', ['d'])
  
  src = [
      'main.d',
      'a.d'
  ]
  executable('tt', src)

• execute meson build && ninja -C build
• execute ./build/tt output in console: test

• change a.d to

  module a;
  
  import std.stdio: writeln;
  
  public void print_in_a(T)(T arg) {
      static assert(false);
      arg.writeln();
  }

• execute ninja -C build

  • expected: message about build failed
  • actual:

    build> /usr/local/bin/ninja
    [1/2] Compiling D object 'tt@exe/a.d.o'
    [2/2] Linking target tt

  after if execute ninja -C build clean && ninja -C build:

  ../a.d(6): Error: static assert  `false` is false
