BTW this raises another issue: if any other program outside mixxx modifies file
tags on disk while the track is loaded to mixxx, same problem with file mmap
garbage can happen, if the mmap is directly to
Why not just add a menu option sync metadata that disables playback and
warns you of the consequences of having files open in other programs before
writing the metadata?

Hi,
I have just ask the Clementine developers about our problem:
http://groups.google.com/group/clementine-player/browse_thread/thread/4e49fe3ddf0a71fe/8754d2fce8fccddf?show_docid=8754d2fce8fccddf#
For my feeling we should take a similar way of writing tags back to the
files.
If this is

Hello,
If created a branch that includes a PreviewDeck, this would fix #366091.
The PreviewDeck is Loaded into Sampler1 for the LateNight1280x800
skin,for testing purpose. I think in the final UI version the
PreviewDeck should be integrated with the libary, any tips on how to
do that?
Hey Keith,
To echo others -- sorry for pissing you off! :) There are reasons we don't
do this though:
Mixxx has to store a lot of metadata about your files (hotcues, loops, bpm,
beats, playlists, crates, play-history, waveform data, etc. in addition to

Hi Owen,
what about file locking?
I think it could be worth a try to lock all files that are loaded to the
decks and sampler for writing.
Does anybody have experience with it?
I have just found:

Hi Robert,
I too am thinking of applying for the GSOC this year. For me, there's
no better way of learning a new piece of software than to dive in and
learn as you go. A good way of getting yourself acquainted with the
code base might be to take a look at a few of the easy bugs, and think

Hi,
I have made some investigations about file locks and mmap.
On Linux file locks are useless for our alleged problem because all
applications have to be cooperative. There is a paper on kernel.org which
describes a mandatory locking, but I have not managed to get it working with
ubuntu.
Hi Stan,
I'm just another new developer, but let me say welcome nonetheless.
I'm sure some of the senior developers will be able to give you better
answers to your compilation issues, for the time being, check out

I think delaying writes till shutdown might be reasonable. The downside is
that if Mixxx crashes then we might not write the data. We could keep a
queue persisted in a database table so that even across crashes we can
write metadata on startup or shutdown.
The TIO cache is still alive and well

As use cases go, I agree, nobody should be tagging tracks with exteral programs
while performing. On the other hand, changing the tag on mixxx screen when you
