Comment (by fw@…):

 Replying to [comment:6 g5pw@…]:
 > Wow, that's great work! Just a small nitpick: there's no need to
 explicitly depend on python2_select since python2.7 has a runtime
 dependency on it. With that corrected I'll happily commit it.

 I thought about that, but I disagree, since I think it's bad practice to
 rely on an indirect dependency for something which is a direct
 requirement.

 For example, if I have a C program that uses something in foo.h, it will
 of course include foo.h.  If foo.h needs something from bar.h, it will
 include bar.h.  But if my code also *directly* uses something from bar.h,
 then it should also include bar.h explicitly, rather than relying on the
 internal include within foo.h.

 In this case, since the Python {{{gpsd}}} code needs a {{{python2}}}
 command, it's appropriate for it to explicitly depend on
 {{{python2_select}}} (which is imperfect in that it doesn't guarantee that
 {{{python2_select}}} has been *used*, but it's the best we can do with
 dependencies).  And strictly speaking, there's no reason in principle why
 {{{python27}}} needs a dependency on {{{python2_select}}}, since it
 probably has no {{{python2}}} commands of its own.  That dependency is
 presumably only there for convenience, given that it's fairly inexpensive,
 making it particularly dangerous to rely on it.

 Once {{{gpsd}}}'s Python code has been updated to be compatible with
 Python 3, the {{{python2}}} issue will become moot.

 > Another thing: if you {{{cd}}} in the port directory and run {{{svn diff
 > port.patch}}} svn should output a patch of everything in one, making
 applying it easier.

 I've attached a diff of that form.
