Subject: [PATCH 24/N] Do not show Error dialogs by default
|
|
|
|
In https://github.com/msys2/msys2-runtime/pull/18, we discussed a change
|
|
that would allow default Windows error handling of spawned processes to
|
|
kick in (such as registered JIT debuggers). We even agreed that it would
|
|
make sense to hide this functionality behind a flag, `winjitdebug`.
|
|
|
|
However, when this got upstreamed as 21ec498d7f (cygwin: use
|
|
CREATE_DEFAULT_ERROR_MODE in spawn, 2020-12-09), that flag was deemed
|
|
unnecessary.
|
|
|
|
But it would appear that it _is_ necessary: As reported in
|
|
https://github.com/msys2/MSYS2-packages/pull/2414#issuecomment-810841296
|
|
this new behavior is pretty disruptive e.g. in CI scenarios.
|
|
|
|
So let's introduce that `winjitdebug` flag (settable via the environment
|
|
variable `MSYS`) at long last.
