Summary: Order of execution of invariant and pre/post conditions Product: D Version: D2 Platform: x86 OS/Version: Windows Status: NEW Severity: normal Priority: P2 Component: DMD AssignedTo: nob...@puremagic.com ReportedBy: bearophile_h...@eml.cc --- Comment #0 from bearophile_h...@eml.cc 2010-10-09 06:36:30 PDT --- This is a D2 program that uses Contracts: import std.c.stdio: printf; class Foo { int x = 0; invariant() { printf("Foo invariant: %d\n", x); assert(x >= 0); } this() { printf("Foo constructor: %d\n", x); x = 0; } void setX(int newx) in { printf("Foo.setX precondition: %d\n", newx); assert(newx >= 0); } out { printf("Foo.setX postcondition: %d\n", x); assert(x == newx); } body { printf("Foo.setX body\n"); x = newx; } } void main() { auto c = new Foo(); c.setX(10); } This is the output of the program, DMD 2.049: Foo constructor: 0 Foo invariant: 0 Foo.setX precondition: 10 Foo invariant: 0 Foo.setX body Foo invariant: 10 Foo.setX postcondition: 10 But I think the Foo.setX precondition needs to run after the Foo invariant, and the Foo.setX postcondition has to run before the Foo invariant.
