[PATCH v3 0/8] MR5665: For a CS_PARENTDC child use parent for visible region calculations.
These patches fix painting in an application that draws outside of a CS_PARENTDC child client area in its WM_PAINT handler.
Comments and suggestions are welcome.
-- v3: win32u: Use parent rectangle for visible region calculations of a CS_PARENTDC child. win32u: Don't clip update region to the window client rectangle. win32u: GetUpdateRect() should clip update rectangle to the window client area. win32u: GetUpdateRgn() should clip update region to the window client area. win32u: Clip PAINTSTRUCT.rcPaint to the window client area. server: For a CS_PARENTDC child use parent for visible region calculations. server: If the being validated region covers whole window then validate everything. user32/tests: Add a message test for listbox redrawing after LB_SETCOUNT.

Hi,
It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.
The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:
The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=146137

I hope that I've fixed discovered test failures, it would be nice to get some comments and reviews.
It has ~100 changed lines (excluding tests) across 8 commits, which is hard to review at a glance.
Would you move test commits prior to fix commits? The test commits will introduce `todo_wine` before `ok()`s expected to fail, and fix commits will remove them. That would make it easier to understand what fixes what.

There's the only single test commit, and it's already a separate one. Remaning patches don't introduce new tests.

Being separate isn't enough, it should be moved earlier in the order of commits.

Yes, which is why I believe this might need more tests.

Let me be clear: "not enough tests" is not a criteria for rejection. It just makes the patch hard to understand and/or verify, which tends to discourage reviewers from looking into it.

Previous comment was wrong about the tests. Sorry for confusion.

Personally I think that existing tests cover most of the being fixed functionality judging by the amount of removed todo_wine statements.
Feel free to suggest the areas of new tests to add though, I'm open to suggestions.
Jinoh Kang (@iamahuman) commented about server/window.c:
struct region *tmp; if (!get_window_visible_rect( win, &rect, frame )) return NULL;
- if (win->parent && is_window_using_parent_dc( win ))
- {
int offset_x, offset_y;if (!get_window_visible_rect( win->parent, &rect, 0 )) return NULL;offset_x = rect.left + (frame ? win->window_rect.left : win->client_rect.left);offset_y = rect.top + (frame ? win->window_rect.top : win->client_rect.top);
This subtracts `rect.left` from `rect.left` and `rect.top` from `rect.top`. In other words, It ignores the left-top coordinate for no apparent reason.
What if the parent window is partially occluded by the frame of ancestors? Then `rect.left` would be larger than the window edge, shifting the update rect further towards upper-left corner.
Instead, this should be changed to something like[^1][^2][^3]:
```suggestion:-1+0 offset_x = win->parent->client_rect.left - win->parent->window_rect.left + win->window_rect.left; offset_y = win->parent->client_rect.top - win->parent->window_rect.top + win->window_rect.top; ```
You can split this into multiple calls to `offset_rect` or just multiple lines if you like.
Also, it would be nice to have tests for the case when `rect.left != win->parent->client_rect.left - win->parent->window_rect.left` (same goes for `top`). Specifically, the test should prevent the suggested code from regressing.

(Note: having the regression test *would be nice*, but is not necessary. Normally I would try to test for this kind of thing, but feel free to skip if it seems like too much work.)

This is how it's done in other places of the code that use offset_x/offset_y variables.

Would you give me an example? I do see several `offset_[xy]`s, but none of them seem to use rect.left/top to subtract it from itself.

I submitted the test as MR !5836. This MR (!5665) fails the added test, and my suggestion fixes it.

What if the parent window is using parent DC too? Shall we ascend the ancestor chain until we meet a non-`CS_PARENTDC` window?

I think that your test answers this question, because "static" and "parentdc_class" both have CS_PARENTDC style.

No worries. Please apply the fix or otherwise address the review before resolving.

Not really, since `CS_PARENTDC` is ineffective for an overlapped window. Sorry for confusion.

To reiterate, the following change is required to get the regions correct:
```suggestion:-1+0 offset_x = win->parent->client_rect.left - win->parent->window_rect.left + win->window_rect.left; offset_y = win->parent->client_rect.top - win->parent->window_rect.top + win->window_rect.top; ```
