Wine Source build on native wchar_t 4 bytes

by Mahin Pandya

Hello All, We are trying to build Wine Source on Linux with native wchar_t size 4 bytes (instead of 2 bytes), is there any way it can be done? I started with doing following changes: diff --git a/tools/winapi/winapi_test b/tools/winapi/winapi_test index b9628e8..91daac3 100644 --- a/tools/winapi/winapi_test +++ b/tools/winapi/winapi_test @@ -206,7 +206,11 @@ sub _find_align_kind_size($) { $align = 2; $kind = "signed"; $size = 2; - } elsif (/^(?:char16_t|wchar_t|USHORT|WCHAR|WORD)$/) { + } elsif (/^(?:wchar_t|WCHAR)$/) { + $align = 4; + $kind = "unsigned"; + $size = 4; + } elsif (/^(?:char16_t|USHORT|WORD|WCHAR_nt)$/) { $align = 2; $kind = "unsigned"; $size = 2; Also started changing some of headers e.g. winnt.h - removed "typedef unsigned short WCHAR;" Any pointers/suggestion are welcome. Thanking you. regards, Mahin

RFC: Allow marking unreliable tests as flaky.

by Francois Gouget

Wine has many unreliable tests which makes it hard to know whether a patch causes new failures. So one proposal was to mark unreliable tests as flaky, and have a mode where flaky failures can ignored by setting $WINETEST_ALLOW_FLAKY. So one would be able to apply a patch, run 'WINETEST_ALLOW_FLAKY=1 make test' and if that fails that means the patch introduces a new failure. The way it works is that when a flaky test fails the message is 'Flaky failed...' instead of 'Test failed...'. I also added the count of flaky failures to the summary line. So the flaky failures are not totally swept under the rug. The main difference is that if $WINETEST_ALLOW_FLAKY is set, the exit code is 0 if the only failures are flaky ones. That still leaves some open questions though: * Should the message be 'Test failed' instead of 'Flaky failed' when $WINETEST_ALLOW_FLAKY is not set? I opted for the latter because it adds information that the failed test has been marked as flaky. * Should tests that fail systematically on some platforms but not others (for instance specific Windows versions, specific locales, specific GPUs) be marked as flaky? Or should flaky be reserved for tests that fail randomly? * What about failures where the message is different every time so that the failure always looks new? Should these not be marked as flaky since it only impacts the TestBot? * On a related note the patch below has flaky_windows and flaky_wine macros. Is that too fine grained? Maybe we don't want to run the risk of marking a test as flaky_windows only to discover later that it can also fail in Wine? But conversely, wouldn't it be valuable to know that a test is only flaky in Wine and not in Windows? Note: flaky_windows is a bit long but I was worried that flaky_win would be too similar to flaky_wine. * I decided having flaky_{windows,wine}_if() macros would be overkill. * How does one know a flaky directive can be removed? * Is it allowed to submit a patch that contains new flaky directives? * Also the flaky directive cannot deal with tests that randomly crash, prematurely exit, or time out. These issues are rarer so maybe we can hope they can all be fixed? * How does this impact bug 48912, aka "Allow blacklisting unreliable and always new failures"? https://bugs.winehq.org/show_bug.cgi?id=48912 * test.winehq.org and the TestBot will need to be updated to highlight the new messages and, more importantly, to recognize the new summary line. The patch is below and I bundled it with tweaks to a few tests for illustration purposes: d3d8:device - Failure happens on Windows (rarely) and Wine. dinput:mouse - Failure happens on Windows 7 and Wine. mmdevapi:render - Timing issue. schedsvc:atsvcapi - Wine-only failure. --- dlls/d3d8/tests/device.c | 2 +- dlls/dinput/tests/mouse.c | 2 +- dlls/mmdevapi/tests/render.c | 2 +- dlls/schedsvc/tests/atsvcapi.c | 2 +- include/wine/test.h | 78 +++++++++++++++++++++++++++++----- 5 files changed, 72 insertions(+), 14 deletions(-) diff --git a/dlls/d3d8/tests/device.c b/dlls/d3d8/tests/device.c index cb1e83b64b3..f0e8c27fafd 100644 --- a/dlls/d3d8/tests/device.c +++ b/dlls/d3d8/tests/device.c @@ -3356,7 +3356,7 @@ static void test_wndproc(void) expect_messages = sc_maximize_messages; SendMessageA(focus_window, WM_SYSCOMMAND, SC_MAXIMIZE, 0); - ok(!expect_messages->message, "Expected message %#x for window %#x, but didn't receive it.\n", + flaky ok(!expect_messages->message, "Expected message %#x for window %#x, but didn't receive it.\n", expect_messages->message, expect_messages->window); expect_messages = NULL; flush_events(); diff --git a/dlls/dinput/tests/mouse.c b/dlls/dinput/tests/mouse.c index 8be808e5da6..dcb5453a825 100644 --- a/dlls/dinput/tests/mouse.c +++ b/dlls/dinput/tests/mouse.c @@ -156,7 +156,7 @@ static void test_acquire(IDirectInputA *pDI, HWND hwnd) SetActiveWindow( hwnd ); hr = IDirectInputDevice_Acquire(pMouse); - ok(hr == S_OK, "Acquire() failed: %#lx\n", hr); + flaky ok(hr == S_OK, "Acquire() failed: %#lx\n", hr); mouse_event(MOUSEEVENTF_MOVE, 10, 10, 0, 0); cnt = 1; diff --git a/dlls/mmdevapi/tests/render.c b/dlls/mmdevapi/tests/render.c index 4e19b91c5f5..882be89b7ff 100644 --- a/dlls/mmdevapi/tests/render.c +++ b/dlls/mmdevapi/tests/render.c @@ -1098,7 +1098,7 @@ static void test_clock(int share) ok(pos == 0, "GetPosition returned non-zero pos before being started\n"); hr = IAudioClient_Start(ac); /* #1 */ - ok(hr == S_OK, "Start failed: %08lx\n", hr); + flaky ok(hr == S_OK, "Start failed: %08lx\n", hr); Sleep(100); slept += 100; diff --git a/dlls/schedsvc/tests/atsvcapi.c b/dlls/schedsvc/tests/atsvcapi.c index 3aaad8b5cfe..83774804b40 100644 --- a/dlls/schedsvc/tests/atsvcapi.c +++ b/dlls/schedsvc/tests/atsvcapi.c @@ -168,7 +168,7 @@ START_TEST(atsvcapi) skip_tests_delete: ret = NetrJobDel(server_name, jobid, jobid); - ok(ret == ERROR_SUCCESS, "NetrJobDel error %lu\n", ret); + flaky_wine ok(ret == ERROR_SUCCESS, "NetrJobDel error %lu\n", ret); skip_tests: SetUnhandledExceptionFilter(old_exception_filter); diff --git a/include/wine/test.h b/include/wine/test.h index 01ba81f4857..422ba3dce38 100644 --- a/include/wine/test.h +++ b/include/wine/test.h @@ -50,6 +50,9 @@ extern int winetest_time; /* running in interactive mode?

Access to graphics memory mappings on upcoming WOW64 implementation

by Derek Lesho

Hi All, In the wake of the new WOW64 implementation (recent explanation [1]), there has been discussion in informal channels about how to we are going to handle pointers to mapped graphics resource memory which we receive from the graphics API, as the possibility exists that it will fall outside of the 32-bit address space. Over time, a few creative solutions have been proposed and discussed, with a common theme being that we need changes in either the kernel or the graphics drivers to do this properly. As we already know the requirements for a solution to this problem, I think it would be responsible to hash this out now and then work with the relevant project maintainers earlier as to avoid blocking work on the wine side too long and to possibly allow more users to test the new path earlier. The solutions which I've seen laid out so far: - Use the mremap(2) interface, allowing us to duplicate the mapping we receive into the 32-bit address space. This solution would match what is already done for Crossover Mac's 32on64 support using Mac's mach_vm_remap functionality [2]. However, right now it is not possible to use the MREMAP_DONTUNMAP flag with mappings that aren't private and anonymous, which rules out there use on mapped FDs from libdrm. Due to this, a kernel change would be necessary. Pro: A uniform solution across all APIs, which could help in the future with any unforeseen need to access host-allocated memory in 32-bit windows code. Cons: Requires a kernel change, which of all the options may take the longest to get up-streamed and in the hands of users. - Work with Khronos to introduce extensions into the relevant APIs enabling us to tell drivers where in the address space we want resources mapped. Pro: Wouldn't require going around the backs of the driver, resulting in a more hardened solution. (Out there, but what if a creative driver returns a mapping without read or write permission and handles accesses through a page fault handler?) Cons: The extension would have to be implemented by each individual vendor for every relevant API. This would implicitly drop support for those with cards whose graphics drivers are no longer being updated. - Hook the driver's mmap call when we invoke memory mappings function, overriding the address to something in the 32-bit address space. Pro: Unlike the other solutions, this wouldn't require any changes to other projects, and shares the advantage of the first solution. Cons: Susceptible to breakage if the driver uses their own mapping mechanism separate from mmap. (Custom IOCTL, CPU driver returning something from the heap) 1: https://www.winehq.org/pipermail/wine-devel/2022-April/213677.html 2: https://www.codeweavers.com/crossover/source - see function `remap_memory` in `wine/dlls/winemac.drv/opengl.c`

[PATCH v4 0/7] Fix LVS_OWNERDATA list view multi select.

by Angelo Haller

From: Angelo Haller <angelo(a)szanni.org> The following patches fix sending of the LVN_ODSTATECHANGED notification for LVS_OWNERDATA list views, adding more refined tests in the process and fixing various bugs. This is v4 fixing the log buffer overflow on the debian test machine by moving some of the up/down key sequences to a later patch. Patch 1/7 still includes the necessary up/down key sequences to validate the fixes in the following patches. The matching up/down key sequences for 1/7 are then introduced in 7/7. I was sadly unable to introduce the test sequence with each fix, as this would require inventing entirely new test sequences, just to work around the debian 32KB log buffer limit. I hope this is ok as it stands. I am also attaching the my remarks from v3, as I don't know if they got ignored due to failing tests: I was sadly not able to trigger any deselect sequences through emulating mouse clicks. I was actually completely unable even send a lef mouse button down at all. Both SendMessage and SendInput fail, on wind and windows. I am unsure if programmatic mouse clicks are even supported in list views? Some forums seem to suggest, that this is only the case for buttons and similar elements. I was following the code snippets in other parts of the comctl32 tests. The other thing might be that the signal is getting caught somewhere in the test code. If anybody has any more insight in this regard, I'd be happy to add additional mouse click tests as well. The other thing I was unable to do is activate the single select tests via SHIFT/+COMMAND to show we need patch 6/6. Windows weirdly informs about the selected item twice, once to inform the item has been selected and then in another call later about the item being focused as well. This seemingly only affects LVS_OWNERDATA listviews from my tests. 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 (7): Add more test cases to ownderdata listviews: comctl32/listview: Fix deselect on LVS_OWNERDATA. comctl32/listview: Move sending LVN_ODSTATECHANGED notifications to a 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/tests: Expand ownerdata listview tests. dlls/comctl32/listview.c | 55 ++++--- dlls/comctl32/tests/listview.c | 253 +++++++++++++++++++++++++++++++-- 2 files changed, 281 insertions(+), 27 deletions(-) Signed-off-by: Angelo Haller <angelo(a)szanni.org> -- 2.36.1

Gitlab experiment wrapup

by Alexandre Julliard

Folks, Here's a summary of the Gitlab experiment discussion, with some additional comments. Thanks to everybody who sent their feedback! * Things that people like: - Fetching commits directly with git instead of applying patches from emails (Huw, Jacek, Paul, Zeb). Indeed that's a major help for me as well. - Better tracker, easy to see the list of pending reviews (Huw). - Possibility to host more Wine projects, as well as private Wine trees to share WIP patches (Jacek). Indeed it would be nice to have all Wine projects in one place instead of the current mix of github/sourceforge/etc. - Potential for automation (Jacek). Gitlab offers many services that we will be able to take advantage of, the most obvious being CI for the testbot. Having all the data in a proper database instead of free-form emails should make it possible to do other interesting things as well. * Some other things I like: - Updating status doesn't need to go through me, people can assign reviewers, supersede patches, etc. directly. That reduces my workload and improves the bus factor. Once we have figured out how to make testbot results reliable, we could also have maintainers merge commits directly. - The full discussion thread for a given MR is readily accessible, it doesn't require hunting down the multiple revisions of a patch and associated threads in the mailman archive. * Things that could be improved: - Signoffs are a bit cumbersome (Rémi). We should change the requirements to something better adapted to Gitlab. - It's only possible to approve the whole MR, not individual commits (Huw, Zeb). I think that's an acceptable trade-off, but we could imagine other approaches. - The mailing list gateway creates too much noise; mixing comments from Gitlab and mailing list isn't very clean (Jacek, Rémi, Alex). We can make some tweaks, or use a separate list, or even rethink the approach of the mail gateway. - Gitlab threading support is limited, nested comment threads are not supported (Zeb). That's true, but looking through the past few months of patch reviews, it seems that we almost never use nested threads, so I think we can live with that limitation. - Reviewers can push fixups to commits, but that requires the author to grant explicit permission (Jacek). Hopefully we can tweak access rights to allow this by default. * Conclusion I think Gitlab is working well for us, and most people seem generally happy with it. So my plan is to go forward and make Gitlab the main development platform for Wine. I'll start working on the transition, and on the improvements mentioned above. Any help will be welcome! I'll be posting a roadmap shortly. -- Alexandre Julliard julliard(a)winehq.org

Test system for the Widl compiler

by Bernhard Kölbl

Hey everyone, during the course of implementing WinRT / UWP stuff, I regularly come across missing IDL 3.0 features in our Widl compiler. Unfortunately, Widl's code seems to have grown in a rater unpleasant direction and is sometimes a real burden to understand and maintain. I think some refactoring to its code would be very well fitting and make things a lot easier for everyone, but refactoring can also bring breakage and makes tracking down errors with Git harder. Additionally, as the code is already not that small, errors have an easy way to slip in without noticing. So to me, the ideal solution seems to add a testing system to the compiler, like most of Wine's components already have. Rémi and I already outlined some ideas: - Port the Winetest system to Unix programs - Make a libwidl or Widl.exe and test against that with our current test system - Add the tests into Widl itself as callable parameter What do you think is the best solution? Getting some suggestions would be great. :) Thanks, Bernhard
