[PATCH v2 resend 0/6] Fix LVS_OWNERDATA list view multi select.

[Angelo Haller]

From: Angelo Haller

The following patches fix sending of the LVN_ODSTATECHANGED notification for
LVS_OWNERDATA list views. A few more refined tests have been added, some
wine_todos removed, and bugs fixed.

This is a v2 resend.

Warning: I have had access to the Windows Research Kernel (WRK) 1.2
~10 years ago. These changes are regarding comctrl32 & tests which are NOT
part of the WRK. As outlined in https://wiki.winehq.org/Developer_FAQ this
should therefore satisfy the requirement of ONLY submitting patches to
components I have NOT had access to.

Angelo Haller (6):
  comctl32/tests: Expand ownerdata listview tests.
  comctl32/listview: Move LVN_ODSTATECHANGED notification to function.
  comctl32/listview: Send LVN_ODSTATECHANGED only for virtual lists.
  comctl32/listview: Send LVN_ODSTATECHANGED notification.
  comctl32/listview: Send LVN_ODSTATECHANGED only for true ranges.
  comctl32/listview: Fix deselect on LVS_OWNERDATA.

Hi Angelo,

Thanks for looking into this. There are a few things can be improved for this series.

Please complete the keyboard sequence by sending WM_KEYUP for VK_DOWN and
WM_KEYUP for VK_UP.

Also please add tests for pressing VK_UP while holding Shift after setting pressing VK_DOWN while holding Shift.
Same for holding both Shift and Control And add checks for NMLVODSTATECHANGE member values. For example,
I don't think uOldState should always be 0.

I'll add the WM_KEYUP events for sure. Not sure how that slipped.

Happy to add more tests for VK_UP.

With regards to the uOldState: I have not found an instance where it is 
not 0. Which kind of makes sense, at least according to the underlying 
logic.

Windows seems to only use LVN_ODSTATECHANGED to set a new state 
(selection of multiple items). For un-setting (uOldState != 0) Windows 
will instead send an all items changed (LVN_ITEMCHANGED = -1) signal 
instead. That is at least what I have observed in my testing.

That test is in this exact patch. This is why I added 
ownerdata_multiselect_deselect_all_select_3_seq. It checks that on 
deslection of multiple items NO LVN_ODSTATECHANGED is send but instead 
LVN_ITEMCHANGED = -1.

Or did i misunderstand?

ownerdata_multiselect_deselect_all_select_3_seq is tested with Shift key released. It would be helpful to see the
deselect message sequence while holding Shift key.

Nitpick. disable -> Disable. There are other places like this.

[PATCH v2 resend 3/6] comctl32/listview: Send LVN_ODSTATECHANGED only for virtual lists.

[Angelo Haller]

From: Angelo Haller

The LVN_ODSTATECHANGED notification should only be sent to lists
that have LVS_OWNERDATA set.

Make sense. It will be better if you can add a simple test before this patch and remove the todo_wines after the fix.

Is this strictly necessary? The call site has special handling for:
infoPtr->dwStyle & LVS_OWNERDATA

We could guard the call to the function at the call site, if that is 
preferred.

Apart from that I am not sure how to write a test for this. This bug is 
triggered by creating a non ownerdata list and selecting multiple 
entries holding shift+ctrl and clicking with the mouse. This will send 
an LVN_ODSTATECHANGED notification where it is not supposed to (as it is 
not an ownerdata list).

I have not found any test examples with mouse emulation. Maybe I missed 
something.

Or should I open a separate bug report for this line?

You can write a test that demonstrate the exact same thing. Create a non onwerdata listview control and test the message sequence doesn't contain LVN_ODSTATECHANGED, which should have a todo_wine
because Wine is currently broken in this case. Then you fix it in the next patch and removes the todo_wine.

As for the mouse emulation, could you do it using only the keyboard? Such as sending VK_DOWN while holding Shift and Ctrl?

This is exactly what I was trying to communicate. I can NOT trigger the 
erroneous sending of LVN_ODSTATECHANGED via the keyboard.

The bug is in LISTVIEW_AddGroupSelection which gets called from 
LISTVIEW_LButtonDown.

Patch 2/6 moves the offending code to a new function 
LISTVIEW_SetOwnerdataState().

This is why I asked about opening a bug report with an contrived 
application that crashes with wine but not with windows.

I just opened a bug report with a test application attached. Hope that 
helps :)

Ok, it's fine to leave the tests.

listviews when LVS_OWNERDATA is set.

Add a test for this as well. You can merge it with the tests for 3/6.

[PATCH v2 resend 6/6] comctl32/listview: Fix deselect on LVS_OWNERDATA.

[Angelo Haller]

From: Angelo Haller

Send one "deselect all items" notification on selection change for
LVS_OWNERDATA listviews instead of notifying about each individual
item change.

Enable LVS_OWNERDATA multi select tests for wine.

Please add a separate test for this. Select and then deselect all items instead of mixing it with other tests.

Maybe the comment needs to be better. Deselect all (-1) is the ONLY 
signal ever sent on ANY deselection,
be it one or multiple items (for LVS_OWNERDATA).
This is how win32 implements it, hence there is no way of making this a 
separate test.

Maybe the line should read:

/* Always send one deselect all (-1) notification for LVS_OWNERDATA 
style instead of
  * informing individual items of deselection */

And I am still looking into the other remarks. Some might need 
reordering as I won't be able to
enable the tests without this last patch.

Thanks for the feedback so far!

I was thinking adding a test that selects items, and them maybe send a mouse click somewhere
in the blank space of the listview control to deselect them all to show that only a -1 notification is sent.
But it may be difficult to get the tests work reliably. If you can't make it work, I guess mixing it with
other tests is okay.

We do not need mouse clicks. See my reply to your comment in 1/6. The 
deselect of multiple items can be triggered by selecting multiple 
holding shift, releasing shift and moving the cursor again. This 
deselects multiple. The code testing for this is already in 1/6.

My comment was with regards to enabling the tests individually. I might 
be able to do so by reordering and spitting some of the patches.

> We do not need mouse clicks. See my reply to your comment in 1/6. The deselect of multiple items can be triggered by selecting multiple holding shift, releasing shift and moving the cursor again. This deselects multiple. The code testing for this is already in 1/6.

Using the keyboard VK_DOWN to deselect simultaneously selects another item. That's why I think it's mixing the results.
You should be able to emulate a mouse click on the blank listview client area to deselect all items, without generating
extra messages. This way we can see only the essential messages are sent and it's clearer.
