duplicate -> #216

[alexanderwhatley]

I wouldn't say this is a duplicate - this question is about spyder in specific, and its not immediately obvious to users that spyder's filesystem watcher is not supported...

@fcicq @alexanderwhatley - It's likely that Spyder is using inotify for its filesystem watcher. Would it be possible to launch Spyder under strace to see what system call is falling over?

It seems to be related to inotify. I don't see the actual inotify system call in this trace, it might be happening from another thread though. It looks like this strace is just of the main thread (no follow forks option).

QInotifyFileSystemWatcherEngine::addPaths: inotify_add_watch failed: Invalid argument

[alexanderwhatley]

@benhillis I reran it with "strace -f"; hopefully this is more informative: https://gist.github.com/alexanderwhatley/99501a1a407ea7e4d1a48169f9957c0d

the first error message comes from qfilesystemwatcher_inotify.cpp from qt.

snippet:

        int wd = inotify_add_watch(inotifyFd,
                                   QFile::encodeName(path),
                                   (isDir
                                    ? (0
                                       | IN_ATTRIB
                                       | IN_MOVE

                                    : (0

                                       | IN_DELETE_SELF
                                       )));
        if (wd <= 0) {
            perror("QInotifyFileSystemWatcherEngine::addPaths: inotify_add_watch failed");
            continue;
}

Inotify has been available in the Insider builds for a few months now, and will be available in the Creators Update. Closing this issue.
