This is a key app needed by many schools and companies, but we haven't had enough time to give it the attention it deserves. Please file a bug report at http://bugs.winehq.org including all the info needed to reproduce the bug (ideally with a trial version; you can find download URLs at http://wiki.winehq.org/AdobeIndesign And attach your test case source there. If you want to go a little further, rewrite your test case in plain C instead of C++ (should be easy). And if you want to go even further, integrate it into our existing message tests, http://source.winehq.org/source/dlls/user32/tests/msg.c which already do have some tests for WM_CTLCOLORSTATIC. One note of caution: the user32/msg.c tests don't all pass on Wine, see http://wiki.winehq.org/MakeTestFailures and http://test.winehq.org/data/520ab5c261706f6118a85a82ba84213932ba76e7/#group… - Dan

Unwanted WM_CTLCOLORSTATIC notification
by Matt J 15 Aug '08

15 Aug '08

Hi, I've been trying to debug a problem with Adobe Indesign CS where the application crashes while creating the file open dialog box. Now I believe (not 100% sure) I have tracked down the problem to a spurious WM_CTLCOLORSTATIC notification. This notification is generated when the application invokes WM_SETTEXT to change the caption of a 'group box' control control in the dialog box. To verify this I coded up a small test case, which I have attached to the email. This basically creates a new dialog box and when it receives it WM_INITDIALOG notification it calls SendDlgItemMessage to send a WM_SETTEXT message to set the text of a 'group box' control on the dialog. As it runs it logs the notifications that it receives. On windows we see the following: Message: 0x00000030 (48) Message: 0x00000110 (272) WM INITDIALOG Message: 0x00000127 (295) Message: 0x00000128 (296) Message: 0x00000018 (24) Message: 0x00000046 (70) ... Under wine we see: Message: 0x00000030 (48) Message: 0x00000110 (272) WM INITDIALOG Message: 0x00000138 (312) Message: 0x00000018 (24) Message: 0x00000046 (70) ... Of primary interest to me here is the WM_CTLCOLORSTATIC notification (0x00000138) that is generated only under wine. Also of interest is that WM_CHANGEUISTATE (0x00000127) and WM_UPDATEUISTATE (0x00000128) notifications are received under windows but not wine. This is my first foray into debugging wine, so I may be totally off track here, but I do believe that the WM_CTLCOLORSTATIC notification is what is causing InDesign to crash. So, I am wondering if someone with more experience here can give some advice about rectifying this problem. If I can provide any more info about the problem, please let me know. Regards, Matt

Re: wininet: default to keep-alive when the server is HTTP/1.1, not when it isn't

That means we defaulted to keep-alive > for HTTP/1.0 servers only, the exact opposite of what we want. This was a problem with the old code too, but what happens when we get HTTP > 1.1 ? Huw.

Flaky tests are starting to get real annoying...
by Dan Kegel 14 Aug '08

14 Aug '08

So, one of the things one learns when writing a patch robot is that flaky tests are very annoying. Each time it gets a new git tree, the robot does five baseline "make -k test" runs, remembers the tests that fail, and doesn't penalize patches for failing any of those tests. See http://code.google.com/p/winezeug/source/browse/trunk/patchwatcher/patchwat… Annoyingly, that's not enough. Some tests stubbornly refuse to fail during the baseline test runs. So I added a second, manual blacklist for those tests; see http://code.google.com/p/winezeug/source/browse/trunk/patchwatcher/patchwat… The list is currently user32:msg.c user32:input.c d3d9:visual.c ddraw:visual.c urlmon:protocol.c kernel32:thread.c and will continue growing as I keep plugging away at getting the patch robot happy. Is anybody else seeing this kind of flakiness? (If you're not, try running patchwatcher for a while :-) FWIW, I'm running the tests on hardy with a fresh metacity (as described in http://wiki.winehq.org/MakeTestFailures ).

Re: user32: test what FindWindow when window isn't found

Introducing 'hWnd' variable is not needed, there is one already called 'found', besides declaring variables in the code is not allowed in Wine. It would be much simpler to add the last error test to 2 existing FindWindowExA calls instead of introducing something looking as foreign code (in indentation, braces usage and spaces). -- Dmitry.
