subversion: enable libmagic support

[ryandesign (Ryan Carsten Schmidt)]

Subversion 1.7 adds a new feature where it can use libmagic to guess file types

​http://subversion.apache.org/docs/release-notes/1.7.html#libmagic-support

Could this be enabled? Thanks.

Do we not have a macports version of libmagic? My quick search only showed some perl modules that appear to build against the system provided one.

[ryandesign (Ryan Carsten Schmidt)]

We do; it's part of the "file" port.

[danielluke (Daniel J. Luke)]

Oh, ick.

The file port installs $prefix/bin/file which has different output from 'normal' file:

% which file
/opt/local/bin/file
% file /usr/bin/file
/usr/bin/file: Mach-O fat file with 2 architectures
% /usr/bin/file /usr/bin/file
/usr/bin/file: Mach-O universal binary with 2 architectures
/usr/bin/file (for architecture x86_64):	Mach-O 64-bit executable x86_64
/usr/bin/file (for architecture i386):	Mach-O executable i386

also, it's nomaintainer :-\

Maybe it makes sense to re-work it to install the 'file' command differently so that everyone who installs subversion doesn't end up with a non-default 'file' command first in their $PATH (since we put $PREFIX before the system paths when we modify $PATH for people)?

Or, maybe we could split the library into a separate port?

I was thinking the same thing -- splitting "file" into two ports "file" and "libmagic". Or rather, keeping the "file" port and adding a "libmagic" subport to it. We'd have to investigate all the ports that currently depend on "file" to see if they need to be changed but hopefully that's not too bad.

Replying to ryandesign@…:

splitting "file" into two ports "file" and "libmagic". Or rather, keeping the "file" port and adding a "libmagic" subport to it.

This is now done (see #38888).
