When starting KDevelop on Windows on some systems, we get several "There is no disk in drive D:\" dialogs. This seems to come from Solid's free space info code, here's a trace (no detailed debug symbols, sorry): Thread 1 (Thread 5316.0x1034): #0 0x00007ffa873209ea in ntdll!ZwOpenFile () from C:\Windows\SYSTEM32\ntdll.dll #1 0x00007ffa84864246 in KERNELBASE!GetDiskFreeSpaceExW () from C:\Windows\system32\KernelBase.dll #2 0x00007ffa69e83e9a in KF5Solid!?trUtf8@DeviceNotifier@Solid@@SA?AVQString@@PEBD0H@Z () from C:\Program Files\KDevelop\bin\KF5Solid.dll #3 0x00007ffa69e83a0e in KF5Solid!?trUtf8@DeviceNotifier@Solid@@SA?AVQString@@PEBD0H@Z () from C:\Program Files\KDevelop\bin\KF5Solid.dll #4 0x00007ffa69e7bbe3 in KF5Solid!?trUtf8@DeviceNotifier@Solid@@SA?AVQString@@PEBD0H@Z () from C:\Program Files\KDevelop\bin\KF5Solid.dll #5 0x00007ffa69e7a42c in KF5Solid!?trUtf8@DeviceNotifier@Solid@@SA?AVQString@@PEBD0H@Z () from C:\Program Files\KDevelop\bin\KF5Solid.dll #6 0x00007ffa69e7dee0 in KF5Solid!?trUtf8@DeviceNotifier@Solid@@SA?AVQString@@PEBD0H@Z () from C:\Program Files\KDevelop\bin\KF5Solid.dll #7 0x00007ffa69e51776 in KF5Solid!?trUtf8@DeviceNotifier@Solid@@SA?AVQString@@PEBD0H@Z () from C:\Program Files\KDevelop\bin\KF5Solid.dll #8 0x00007ffa6d917229 in KF5KIOFileWidgets!?dir@KRecentDirs@@YA?AVQString@@AEBV2@@Z () from C:\Program Files\KDevelop\bin\KF5KIOFileWidgets.dll #9 0x000000006d38c38e in Qt5Core!?event@QObject@@UEAA_NPEAVQEvent@@@Z () from C:\Program Files\KDevelop\bin\Qt5Core.dll #10 0x000000006d6bc5a6 in Qt5Widgets!?notify_helper@QApplicationPrivate@@QEAA_NPEAVQObject@@PEAVQEvent@@@Z () from C:\Program Files\KDevelop\bin\Qt5Widgets.dll #11 0x000000006d6bbba6 in Qt5Widgets!?notify@QApplication@@UEAA_NPEAVQObject@@PEAVQEvent@@@Z () from C:\Program Files\KDevelop\bin\Qt5Widgets.dll #12 0x000000006d367609 in Qt5Core!?notifyInternal2@QCoreApplication@@CA_NPEAVQObject@@PEAVQEvent@@@Z () from C:\Program Files\KDevelop\bin\Qt5Core.dll #13 0x000000006d36834a in Qt5Core!?sendPostedEvents@QCoreApplicationPrivate@@SAXPEAVQObject@@HPEAVQThreadData@@@Z () from C:\Program Files\KDevelop\bin\Qt5Core.dll #14 0x00007ffa5e82546f in qwindows!qt_plugin_instance () from C:\Program Files\KDevelop\bin\platforms\qwindows.dll #15 0x000000006d3b47b6 in Qt5Core!?activateEventNotifier@QEventDispatcherWin32Private@@QEAAXPEAVQWinEventNotifier@@@Z () from C:\Program Files\KDevelop\bin\Qt5Core.dll #16 0x00007ffa86fd24fd in USER32!DispatchMessageW () from C:\Windows\system32\user32.dll #17 0x00007ffa86fd2357 in USER32!NotifyWinEvent () from C:\Windows\system32\user32.dll #18 0x000000006d3b58de in Qt5Core!?processEvents@QEventDispatcherWin32@@UEAA_NV?$QFlags@W4ProcessEventsFlag@QEventLoop@@@@@Z () from C:\Program Files\KDevelop\bin\Qt5Core.dll #19 0x00007ffa5e825449 in qwindows!qt_plugin_instance () from C:\Program Files\KDevelop\bin\platforms\qwindows.dll #20 0x000000006d365020 in Qt5Core!?exec@QEventLoop@@QEAAHV?$QFlags@W4ProcessEventsFlag@QEventLoop@@@@@Z () from C:\Program Files\KDevelop\bin\Qt5Core.dll #21 0x000000006d367c47 in Qt5Core!?exec@QCoreApplication@@SAHXZ () from C:\Program Files\KDevelop\bin\Qt5Core.dll #22 0x00007ff6ce0ed64d in ??

Git commit f544380db86301f4833b2149dd46dca47acc8042 by Kevin Funk. Committed on 18/10/2016 at 07:33. Pushed by kfunk into branch 'master'. Windows: Don't display error dialogs Summary: Some Windows API functions like GetDiskFreeSpaceEx may produce error dialogs. This is not desired. Fix this by temporarily blocking errors by calling SetThreadErrorMode with certain error suppressing flags.
