Greetings,
The following webrev contains fixes for the following issue:
15169 image-update plans twice and keeps both
webrev:
http://cr.opensolaris.org/~swalker/pkg-mem/
image-update (via the pkg.client.api) calls plan_update_all().
plan_update_all calls ipkg_is_up_to_date check which does a plan_install
to see if the pkg(1) client needs updating.
If that succeeds, it then does a make_udpate_plan for all packages on
the system. However, when it creates the second plan, the first plan
isn't discarded first.
Because the first plan isn't discarded, a significant amount of memory
can't be re-used before the new plan is started. The fix for this is to
simply always discard the current imageplan before creating a new one.
b131 system using /dev and /extra repositories (redistributable not
installed):
$ pfexec pkg -R / image-update -n
First Column of pmap -x total output at end of operation:
Gate Tip Peak Memory: 759,572KB
Gate Tip + Patch Peak Memory: 634,444KB
The workaround for older clients is to simply use the -f option to
image-update, which gives a very similar reduction in memory usage.
Cheers,
