QFileSystemWatcher's signal "directoryChanged" not emitted
-
Might be worth you looking directly at the source code, see if you can get it sorted yourself, and submit a patch.
Did you try if other environments are affected too? Any linux distribution for example?
@VRonin I didn't try all the OS, but I can later, but under linux there isn't any difference between del and shift+del like under windows (because I tested that with del under win10 so when you put the folder in the trashcan, but did'nt test really with shift+del...I think with shift+del under win7 it is ok but not sure 100%
I will do more test so....
but I have already looked at the code of QFile SystemWatcher for one year because of the older bug and I don't really understand it....if I could understand it I would have made myself the correction.I will try again to look at the code of QFileSystemWatcher -

@VRonin OK there is the same problem under linux debian 8 with kde.when you move to thrash a subdirectory watched the signal directorychanged is not emitted and when you delete it with shift+del the signal is emitted...I have just tested now
under windows 7 I can only delete with shift+del it doesn't allow me to delete with del so there isn't any problem
I didn't test under mac os -

@VRonin I have looked quickly at the source code of QFileSystemWatcher....(Qt5.6.2)
first I don't find the definition of init() and initPollerEngine() of the class QFileSystemWatcherPrivate (qfilesystemwatcher_p.h) that are called in the constructor of QFileSystemWatcher and in the method addPaths.
second, I have seen that there is a thread that derivate from QThread for windows, QWindowsFileSystemWatcherEngineThread, and the method run is redefinited l332 in qfilesystemwatcher_win.cpp,so that I understand it but don't understand all the details in the method run... -

@VRonin I have seen where it emits the signal directoryChanged when the directory is deleted l.388 and l.385 I see if(fakeRemove||!fileInfo.exists()) but I don't understand the other things well.....

@VRonin I have looked too at the win32 functions findfirstchangenotification (used l.160) and find nextchangenotification (used l.364)....I think I must use a debug version of Qt to debug that because perhaps there is no change notification on the handle when we use a simple del to delete a directory ie send it to trashcan(without shift) ?

@VRonin or perhaps the error l.367 is another error than ERROR_ACCESS_DENIED that should be considered too and the that fakeRemove should be put to true too (or another boolean )

@VRonin what are the other errors of FindNextChangeNotification?didn't find them in the win32 msdn documentation.
And I don't really know how to do debug of Qt ? because it is in QtCore,so I suppose I must take the project and source of QtCore, but my test project use not only QtCore but QtGui and QtWidget too.... -
@VRonin Thank you vronin, do you know how I can debug QtCore (or corelib or io) with my test project synchro as executable with QtCreator and mingw-w64(the compiler of qt.io).I suppose I must take the source (single,the .zip) but don't really know how to do that.my project synchro uses core,gui and widget but I suppose I must open corelib or io as project in QtCreator
-
@VRonin do you know how to get the version 5.6.2 of qtbase from code.qt.io with git? (to build it in debug and try to debug corelib)
-
@VRonin ok thanks vronin...
-
@VRonin it is done.but to debug qfilesystemwatcher should I open corelib.pro in QtCreator (QtCore) and build it debug and put breakpoints and attach to my app synchro ?
-
@VRonin I want to put a breakpoint l.364 of QFileSystemWatcher_win.cpp and watch error l365
-
@VRonin there is "attach to unstarted application" and "debug an external application" in Qtcreator\debug. is it possible to use one this option to debug QtCore (corelib) with my app synchro.exe ?
-
@VRonin when building corelib I have this error ..\corelib\global\qt_pch.h:50:21: fatal error: qglobal.h: No such file or directory
#include <qglobal.h>
qglobal.h is in the directory but I think I lacks an environment variable ? -
@VRonin OK I think I have found : I have copied the directory include of the source single (.zip) of 5.6.2 in the direcorty qtbase and I have put in my environment variable INCLUDE the path of directory include and reboot my windows...I think it will be ok

I have put
INCLUDEPATH +="../../include"
INCLUDEPATH +="../../include/QtCore"int he corelib.pro but I have an error In file included from ..\corelib\animation\qabstractanimation.cpp:143:0:
..\corelib\animation\qabstractanimation_p.h:52:31: fatal error: private/qobject_p.h: No such file or directory

#include <private/qobject_p.h>It think I will build the whole Qtbase as usually and then open the corelib.pro and put the directory of lib QtCored.dll as build directory and try to debug with my exe (synchro.exe)
-
You have to, qtbase, unlike the other modules, requires that you run configure before building it.
