I’ve finally pushed some code that I’ve ended up working on in two different hemispheres!

With the putback of:

	15305 need to generate dependency information from SMF manifests
	15306 need an attribute to declare the SMF services a package delivers
	15722 pkgdepend doesn't always remove internal deps when variants taken into account

pkgdepend(1) will now use SMF manifests as a source for dependency information.

This means, that if you as a package author are including SMF manifests in your package, the package publishing system will look in those manifests for any service descriptions that declare other FMRIs as “require_all” dependencies for your service, and will then ensure that the packages delivering those services are marked as dependencies for the package you’re publishing.

Obviously to do this work, pkgdepend needs to be run on a build machine that includes all SMF FMRIs that your package needs to function. That said, having your publishing system figure out dependencies for you, means there’s one less thing for you as a publisher to worry about, and certainly will make life easier for your users.

An interesting side-effect of this work, is that now you’ll be able to search the package database for SMF manifest FMRIs. For example, if you’re wondering who delivers svc:/network/iptun:default, you can do a simple search for it –

$ svcs iptun
STATE          STIME    FMRI                                
online         May_27   svc:/network/iptun:default
$ pkg search -l ':::svc\:/network/iptun\:default'
INDEX                ACTION VALUE                      PACKAGE
opensolaris.smf.fmri set    svc:/network/iptun:default pkg:/SUNWcs@0.5.11-0.142

(though do remember to escape the colons in the SMF FMRI field. Wildcards also work, so for kicks, you might want to try pkg search -l ':::svc\:* :-)

Enjoy!
