I might be a bit offtopic, but I saw "file monitor rewrite" and I had to jump in... Currently GFileMonitor doesn't have a unique way to know whether a file got closed. There is the changes-done-hint event, but that covers IIRC 2 things: files getting closed and also a "virtual" emission which happens after some time even if the files were not closed (think of a log file which never gets closed). The main issue is that if you want to get notified of when a file was fully updated *and* closed, you need to fallback to raw inotify. The rationale for wanting to get notified only when the file got closed is e.g. Tracker monitoring the Downloads/ directory. We may not want to extract file info for an ongoing download, just for when the download is fully finished (and destination file closed). More background here: https://bugzilla.gnome.org/show_bug.cgi?id=635765 alexl noted that non-Linux systems may not have support to notify files closed, so removing the changes-done-hint virtual emission wasn't an option in GLib. Still, I think that the original (obsoleted) patch in that bugreport (which allows to at least disable the virtual emission via a property) may be useful for Linux/inotify users. For other backends we could just ignore the disabling possibility... - -- Aleksander -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iEYEARECAAYFAlS3pF0ACgkQgxIgkKLogl4iTgCg4dT1pkiYnWIhWWqsqlYeHJ81 DV0AoKebTjbp0uG7uufpjBNI3Gspj9IZ =hSJg -----END PGP SIGNATURE----- _______________________________________________ gtk-devel-list mailing list gtk-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-devel-list
