I have a package that is going to become obsolete, but its contents

I think the best way to do that is to bump your package revision,
change
it's category to _obsolete, make it's contents empty, and make it
depend
on the packages which are replacing it.

Yes, that was my first thought.  But there's no longer a source file
for
the obsolete package[1], and cygport complains that SRC_URI must be
defined.  Maybe cygport should be patched to allow an empty SRC_URI
when
the category is _obsolete.  Or do you see another way around this?

I would think you can use the same SRC_URI as previously, but set
PKG_CONTENTS="" and PKG_IGNORE="*" ?

You're right, I can do something like that.  I was being overly pedantic
in wanting SRC_URI to be "accurate".  Sorry for the noise.

You can always make an empty tarball called
texlive-collection-htmlxml-20170515.tar.xz or whatever, and use that for
SRC_URI.

Good idea, thanks. But it turns out that there's another problem: cygport won't actually create an empty binary tarball in this situation.

The relevant code is in pkg_pkg.cygpart around lines 149--163, especially this part:

		elif (( pkg_count == 1 ))
		then
			pkg_contents="*"
		else
			pkg_contents=

We get here if PKG_CONTENTS is unset or empty. (There's actually no test to see if it's set but empty.) In the situation under discussion, this results in pkg_contents="*" followed by a tar error.

Yaakov, shouldn't the user be allowed to explicitly set PKG_CONTENTS empty and have cygport honor that, at least for obsolete packages?
