Package: apt-file
Version: 3.2.2
Severity: wishlist

Dear Maintainer,

I don't like (apt's) PDiff feature, so I disable it everywhere. However,
on the few machines/chroots where I like to install apt-file,
/etc/apt/apt.conf.d/50apt-file.conf is installed, which set's 'PDiffs
"true";', overwriting my configuration choice from /etc/apt/apt.conf.d/$mine.

Could you please ship a /etc/apt/apt.conf.d/50apt-file.conf by default,
which doesn't do that?

Thanks for maintaining apt-file!

tschau,
	Holger

We made the choice to do it like this, because, while disabling PDiffs can
have some advantages for a small set of users on Packages and Sources files,
the advantages for Contents files affect an even much smaller set of users.

Given that a lot of users are using Pdiff false to due to historic performance
issues, the choice was made to default Contents files to enabled, even if users
manually disabled Pdiffs by default; as disabling Pdiffs for Contents files
produces terrible results in almost all cases - because they are huge files.

I'm not sure there are connections and machines where pdiffs for Contents files
are slower than fresh Contents files. Having to download the Contents file, and
decompress it takes a lot of time, compared to decompressing the lz4 stored local
file, downloading patches and patching it.

You are free to override the options apt-file sets for those targets, and I suggest
you do so if you believe that Pdiffs are worse for you.
