[Bug 133554] Re: Rebuilding collection eats up too much memory

[Jeff Mitchell]

Fernán,

You should pester the Ubuntu packagers for updated ntfs-3g.  I'm really
surprised they're not on top of it, considering the risks of bugs in
filesystem drivers.

Anyways, Amarok will indeed relaunch the scanner process a number of
times.

As for the .m4a and .torrent files...

Amarok distributes addons to TagLib that should handle m4a files, but
there's always a chance it's buggy...that, or the Ubuntu maintainers may
remove that capability from the build, in which case the collection
scanner can't handle those files...might want to check with the package
maintainers about that.

So, what appears to be happening is the the scanner is hanging on non-
music files, or music files it can't parse for some reason.  I've seen
this before, but I'm not sure of the cause...as far as I'm aware, it's
supposed to detect files it can't handle and skip past them...but I
could be wrong, as I didn't write the scanner code.  Sometimes there are
legit music files that may have had tags improperly written...or
sometimes, legit music files or files that TagLib should skip over but
some bug or another in TagLib causes it to act haywire.  Unfortunately
there hasn't been a TagLib official release since 1.4, even though there
have been a ton of patches and bugfixes to the source code, so how many
of those bugfixes you have depend on when the package was built, and
what patches they added (or if they took a snapshot of the Subversion
tree).  So another thing you could try is pestering the TagLib packager
to make a package of a current Subversion snapshot, and if they do it,
see if that helps anything.

But in the end, I think your best bet is to clean out the files that the
scanner seems to be stopping on.  Each time you hit a file that it seems
stuck on, move it to an alternate directory and try again.  If you do
this, I'd like to try to get some of those files from you so that I can
test them out here and try to fix the problems (if these are the cause).

Hope that helps.
