Hi misc@ and Marc,
I have a script for applying all updates/upgrades for upgrading my OpenBSD
workstation, dev machines, and servers. I'm currently in the process of
improving it to better support downloading pending updates in advance of
actual review and installation (see <
https://github.com/morgant/swupdate-openbsd/issues/14>. I've been studying
the pkg_add(1) manual, testing, and also reviewing the pkg_add Perl source
in src/usr.sbin/pkg_add/OpenBSD/, but while really well structured and easy
to read, the latter does take me longer to grok than the former.
I'm hoping you have a quick answer (even if it's 'no') to the following
question: Does `pkg_add -u` utilize PKG_CACHE other than with the `-n`
option?
In my testing (on amd64/7.3-stable), the following will check for updates
and copy packages to `PKG_CACHE`, as described in pkg_add(1):
PKG_CACHE=/home/_swupdate/7.3/packages/amd64 pkg_add -nu
If I delete a cached package from the PKG_CACHE directory, re-executing the
above command will redownload the package. That's what I was hoping for.
I'm not quite sure whether some of the packages are being re-downloaded by
just looking at file modification dates (unfortunately, `-vvvvv` doesn't
note downloads, nor cache mis/hit.)
The following seems to try to update packages from PKG_CACHE, if passed in
as PKG_PATH, but -- understandably -- does result in errors that some
packages (those that didn't need updates or have dependencies that did)
could not be found:
PKG_PATH=/home/_swupdate/7.3/packages/amd64 pkg_add -u
Naturally, if I append ':installpath' to the above PKG_PATH, it will not
give such errors:
PKG_PATH=/home/_swupdate/7.3/packages/amd64:installpath pkg_add -u
However, since '-vvvvv' also doesn't note which package repository (esp.
local or not) a package was processed from, I don't know whether it's
actually preferring the local repository.
Additionally, if I set both PKG_CACHE and PKG_PATH to `pkg_add -u`, it
doesn't appear that packages are downloaded to PKG_CACHE:
PKG_CACHE=/home/_swupdate/7.3/packages/amd64
/home/_swupdate/7.3/packages/amd64
pkg_add -u
This is confirmed by deleting a package from PKG_CACHE and re-executing the
above, after which the deleted package is still missing from PKG_CACHE. Of
course, this absolutely feels sketchy to be caching to a package
repository, but was worth a try.
Thanks in advance,
Morgan
