Btrfs Heatmap - v5 ... snake, linear ... the virtual address space
Hi,
I just tagged v5 of the Btrfs Heatmap utility, which visualizes the usage of your btrfs filesystem:
https://github.com/knorrie/btrfs-heatmap
The main changes are:
* [e464bfc] New --curve to select either hilbert, linear or snake
* [b722ff4] New --sort to sort a full filesystem picture by eitherdev_extents (--sort physical, default) or by chunk/stripes (--sort virtual)
* Improved documentation, mainly about the curve alternatives [0] and
about the new virtual address space option [1], but also other small improvements.
* debian branch with packaging files
[0] https://github.com/knorrie/btrfs-heatmap/blob/master/doc/curves.md
[1] https://github.com/knorrie/btrfs-heatmap/blob/master/doc/sort.md
Since I got tired of cloning and updating the thing all over the place, I added debian packaging. I'm planning to get all of it into Debian unstable after the Stretch release.
For the impatient, use pbuilder or grab it from our repo at $dayjob:
http://packages.mendix.com/debian/pool/main/b/btrfs-heatmap/
http://packages.mendix.com/debian/pool/main/p/python-btrfs/
Have fun! And, share some of your results, if you have nice pictures or create timelapses of filesystems behaving or misbehaving. :)

Why would you wait until after the release? For packages not in testing, unstable is fully open. NEW processing is somewhat sluggish, but the hard part, getting there, is full of bored people who can help. Not sure if you have a pet DD around -- if not, I for one can help with review/upload.

Here's a brief review:
There's a bunch of issues caught by automated tools. You can run "lintian -i *.changes", both on source and binary packages. With -i, lintian gives a helpful explanation how to fix problems it finds.
btrfs-headmap:
"Section" shouldn't be "python", it's merely written in python, not a
library or a python-specific tool
man page should explain what the image says (colors, etc).
python-btrfs:
The python team wants to get rid of python2 as soon as possible. As there's no legacy code using this package, what's the point of providing python2 versions?
Meow!

Ah. I see.

Nope. That would be great, I would really appreciate that.

Yeah, so have some more, the minimal parts of the online documentation, in there.

True. Probably I should just go python 3 only anyway. If so, better sooner than later.
It was interesting to see how much effort it would take to support both, but it already turned into an annoyance and extra work and fragility now. For python-btrfs, it's the fs tree which I'm working on now where things like filenames start causing the real headaches.
