Error when reading files - AttributeError: 'Buffer' object has no attribute 'headers'

[Elizafox]

Hi,

cp gives me this error when I try to copy files:

elizabeth@ein ~/google_music/artists/crudbump/2012 - real art $ cp 002\ -\ white\ house.mp3 ~
cp: error reading ‘002 - white house.mp3’: Bad address
cp: failed to extend ‘/home/elizabeth/002 - white house.mp3’: Bad address

The debug log is filled with stuff like this:

DEBUG:fuse.log-mixin:<- open 32768
DEBUG:fuse.log-mixin:-> read /artists/crudbump/2012 - real art/006 - i'm meaty.mp3 (16384L, 0, 32768L)

(Those were for two different files obviously, but the outcome is the same)

Okay, after investigating the issue...

It tries to get the urllib2 handle like so, a few lines prior:

u = self.__open_files.get(fh, None)

In the open function, around line 302, it does this:

        #Check for multi-part 
        if len(urls) > 1:
            self.__open_files[fh] = self.__open_multi_part(urls, path)
        else:
            u = self.__open_files[fh] = urllib2.urlopen(urls[0])
            u.bytes_read = 0
        return fh

Spot the bug in __open_multi_part ;p

    def __open_multi_part(self, urls, path):
        """Starts a thread to download a multi-part track (Google Play All
        Access) into a single file in the cache directory and return
        an open file handle for it while it downloads.
        """
        buf = fifo.Buffer()
        # Start downloading the multi part track in another thread:
        downloader = AllAccessTrackDownloader(urls, buf, path)
        downloader.start()
        # Return the buffer, while the download is still happening:
        return buf
