nim-lang / Nim

Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula. Its design focuses on efficiency, expressiveness, and elegance (in that order of priority).

Union Object Initializer ```error: extra brace group at end of initializer``` #20653

Open LukeDeWaal opened 1 year ago

LukeDeWaal commented 1 year ago

What happened?

I have encountered this issue (#10815) or something related in my project with the following example code:

type
  EmptySeq* {.bycopy.} = object

  ChoiceWithEmptySeq_d* {.bycopy.} = object
    a*: bool

  INNER_C_UNION* {.bycopy, union.} = object
    a*: char
    b*: EmptySeq
    c*: byte
    d*: ChoiceWithEmptySeq_d

  ChoiceWithEmptySeq_selection* = enum
    ChoiceWithEmptySeq_NONE, 
    ChoiceWithEmptySeq_a_PRESENT,
    ChoiceWithEmptySeq_b_PRESENT,  
    ChoiceWithEmptySeq_c_PRESENT,
    ChoiceWithEmptySeq_d_PRESENT

  ChoiceWithEmptySeq* {.bycopy.} = object
    kind*: ChoiceWithEmptySeq_selection
    u*: INNER_C_UNION

  Og_Context* {.bycopy.} = object
    state*: int
    init_done*: bool
    ch*: ChoiceWithEmptySeq
    em*: EmptySeq

var context* : Og_Context = Og_Context(init_done: false)

The generated C code attempts to initialize the Object as: {0, NIM_FALSE, {0, {0, {}, 0, {NIM_FALSE}}}, {}} while it should in fact be: {0, NIM_FALSE, {0, 0}, {}}. It tries to populate the Union as if it is a regular object, while it should only initialize a single field.

This bug does not occur when manually initializing the Union:

var context* : Og_Context = Og_Context(init_done: false, 
                                       ch: ChoiceWithEmptySeq(kind: ChoiceWithEmptySeq_a_PRESENT, 
                                                              u: INNER_C_UNION(a: '\0')))

I've been hitting a similar issue in our nim-eth code base.

Minimized (does still use chronos) code snippit:


import chronos

type
  Socket* = object
    a*: int

  ErrorType* = enum
    ErrorA, ErrorB

  Error* = object
    case kind*: ErrorType
    of ErrorA:
      discard
    of ErrorB:
      discard

proc connect(s: Socket): Future[Error] {.async: (raises: [CancelledError]).} =
  discard

let socket = Socket(a: 123)
let res = waitFor socket.connect()

Compiles fine with Nim 1.6.20:

Note that not using the object variant but instead directly the ErrorType makes the compiling succeed.
