|
|
// QFileSystemWatcher should allow us to watch for files being

|
// removed or renamed. It uses kqueues and EVFILT_VNODE on FreeBSD,
|
|
// NetBSD, FSEvents on macOS, inotify on Linux if available, and
|
|
// FindFirstChagneNotification() on Windows. On all other platforms,
|
|
// it just periodically polls, as we're doing now.
|
|
//
|
|
// For unmounts:
|
|
//
|
|
// macOS and FreeBSD deliver NOTE_REVOKE notes for EVFILT_VNODE, and
|
|
// QFileSystemWatcher delivers signals for them, just as it does for
|
|
// NOTE_DELETE and NOTE_RENAME.
|
|
//
|
|
// On Linux, inotify:
|
|
//
|
|
// http://man7.org/linux/man-pages/man7/inotify.7.html
|
|
//
|
|
// appears to deliver "filesystem containing watched object was
|
|
// unmounted" events. It looks as if Qt turns them into "changed"
|
|
// events.
|
|
//
|
|
// On Windows, it's not clearly documented what happens on a handle
|
|
// opened with FindFirstChangeNotification() if the volume on which
|
|
// the path handed to FindFirstChangeNotification() is removed, or
|
|
// ejected, or whatever the Windowsese is for "unmounted". The
|
|
// handle obviously isn't valid any more, but whether it just hangs
|
|
// around and never delivers any notifications or delivers an
|
|
// event that turns into an error indication doesn't seem to be
|
|
// documented. If it just hangs around, I think our main loop will
|
|
// receive a WM_DEVICECHANGE Windows message with DBT_DEVICEREMOVECOMPLETE
|
|
// if an unmount occurs - even for network devices. If we need to watch
|
|
// for those, we can use the winEvent method of the QWidget for the
|
|
// top-level window to get Windows messages.
|
|
//
|
|
// Note also that remote file systems might not report file
|
|
// removal or renames if they're done on the server or done by
|
|
// another client. At least on macOS, they *will* get reported
|
|
// if they're done on the machine running the program doing the
|
|
// kqueue stuff, and, at least in newer versions, should get
|
|
// reported on SMB-mounted (and AFP-mounted?) file systems
|
|
// even if done on the server or another client.
|
|
//
|
|
// But, when push comes to shove, the file manager(s) on the
|
|
// OSes in question probably use the same mechanisms to
|
|
// monitor folders in folder windows or open/save dialogs or...,
|
|
// so my inclination is just to use QFileSystemWatcher.
|
|
//
|
|
// However, that wouldn't catch files that become *re*-accessible
|
|
// by virtue of a file system being re-mounted. The only way to
|
|
// catch *that* would be to watch for mounts and re-check all
|
|
// marked-as-inaccessible files.
|
|
//
|
|
// macOS and FreeBSD also support EVFILT_FS events, which notify you
|
|
// of file system mounts and unmounts. We'd need to add our own
|
|
// kqueue for that, if we can check those with QSocketNotifier.
|
|
//
|
|
// On Linux, at least as of 2006, you're supposed to poll /proc/mounts:
|
|
//
|
|
// https://lkml.org/lkml/2006/2/22/169
|
|
//
|
|
// to discover mounts.
|
|
//
|
|
// On Windows, you'd probably have to watch for WM_DEVICECHANGE events.
|
|
//
|
|
// Then again, with an automounter, a file system containing a
|
|
// recent capture might get unmounted automatically if you haven't
|
|
// referred to anything on that file system for a while, and get
|
|
// treated as inaccessible. However, if you try to access it,
|
|
// the automounter will attempt to re-mount it, so the access *will*
|
|
// succeed if the automounter can remount the file.
|
|
//
|
|
// (Speaking of automounters, repeatedly polling recent files will
|
|
// keep the file system from being unmounted, for what that's worth.)
|
|
//
|
|
// At least on macOS, you can determine whether a file is on an
|
|
// automounted file system by calling statfs() on its path and
|
|
// checking whether MNT_AUTOMOUNTED is set in f_flags. FreeBSD
|
|
// appears to support that flag as well, but no other *BSD appears
|
|
// to.
|
|
//
|
|
// I'm not sure what can be done on Linux.
