./sysutils/bup, Highly efficient file backup system based on the git packfile format

Branch: CURRENT, Version: 0.32nb3, Package name: bup-0.32nb3, Maintainer: gdt

bup is a program that backs things up. bup has a few advantages over other
backup software:

It uses a rolling checksum algorithm (similar to rsync) to split large files
into chunks. The most useful result of this is you can backup huge virtual
machine (VM) disk images, databases, and XML files incrementally, even though
they're typically all in one huge file, and not use tons of disk space for
multiple versions.

It uses the packfile format from git (the open source version control system),
so you can access the stored data even if you don't like bup's user interface.

Unlike git, it writes packfiles directly (instead of having a separate garbage
collection/repacking stage) so it's fast even with gratuitously huge amounts of
data. bup's improved index formats also allow you to track far more filenames
than git (millions) and keep track of far more objects (hundreds or thousands of

Data is "automagically" shared between incremental backups without having to
know which backup is based on which other one - even if the backups are made
from two different computers that don't even know about each other. You just
tell bup to back stuff up, and it saves only the minimum amount of data needed.

bup now supports Python 3

sysutils/py-fuse-bindings was the only dependency that required Python
2, which is now ported to Python 3.

Log message:
sysutils/bup: Update to 0.32

(This commit message rides a trivial comment change, and is what
should have been on the 0.32 update earlier.  Thanks again to wiz who
amazingly reads all the commit messages carefully.)

Notable changes in 0.32 since 0.31)

* Python 3 is now preferred.  Python 2 support is deprecated, and it's
  possible that we'll stop new development for Python 2 fairly soon.
  If so, we'll probably continue to fix bugs in the last Python 2
  compatible version for a while, but please make plans to migrate.

  At the moment, ./configure doesn't explicitly look for any python
  newer than python3.8 by default (though one might be selected by the
  eventual python3 fallback).  If desired, you can explicitly select a
  version like this:

      PYTHON=python3.9 ./configure

* With Python 3.9, the command line reported in tools like `ps` and
  `top` will be `python...` rather than `bup...`.  This was caused by
  an upstream change that appears to have been reverted.  We're likely
  to avoid the issue entirely in a future relese.


* A number of Python 3 compatibility problems have been fixed.

* `bup web` should no longer crash when attempting to listen on IPV6

* `bup restore -vv` should no longer crash when printing paths with
  Python 3.

* `bup --prune-older --pretend` should format the plus/minus lines
  correctly now.

* The `TTY_WIDTH` should now be correctly propagated to subprocesses
  and remotes..

* Errors encountered while writing packfiles should be handled more

* Some issues with the handling of integral type signs and sizes on
  the C side have been fixed.

Build and install

* The tests are now handled by pytest.  See the
  [README](../README#getting-started) for the additional dependency
  information and further instructions.
