Description Duncan 2018-11-24 22:24:56 UTC
Nutshell ($PF expanded):

!!! can't process invalid log file: /tmp/portage/$PF/temp/logging/instprep

Is instaprep related to recent changes regarding FEATURES (listed below) I have turned off, and it isn't prepared for the absence of the file due to having the features turned off?

I recently started seeing this (AFAIK harmless but it looks alarming) warning on at least some merges.  I suspect it may be on all of them, but I don't normally see the full logs on successful merges due to running parallel, and the warning apparently doesn't show up in the per-package message summary at the end, only in the full log.

This specific example is taken from an individual elfutils binpkg downgrade run (due from elfutils-0.175 due to the recent masking, run individually after seeing it in the --update --deep --ask output, in ordered to take advantage of the older binpkg):

>>> Regenerating /etc/
>>> Original instance of package unmerged safely.
>>> dev-libs/elfutils-0.173 merged.
>>> Regenerating /etc/
!!! can't process invalid log file: /tmp/portage/dev-libs/elfutils-0.173/temp/logging/instprep
>>> Auto-cleaning packages...
>>> No outdated packages were found on your system.
* GNU info directory index is up-to-date.

In case it's FEATURES related, note that at the last portage upgrade I decided it was time to update them, specifically matched my FEATURES list against that in the manpage, and explicitly set each one either FEATURE or -FEATURE.  I know I deleted an outdated one or two but don't remember whether I actually activated/deactivated any of the current ones.  Here's what portage reports as active now:

FEATURES="binpkg-docompress binpkg-dostrip binpkg-logs buildpkg buildsyspkg candy ccache cgroup collision-protect config-protect-if-modified distlocks downgrade-backup ebuild-locks fixlafiles ipc-sandbox merge-sync mount-sandbox network-sandbox news parallel-fetch parallel-install pid-sandbox protect-owned sandbox sfperms strict strict-keepdir unknown-features-warn unmerge-logs unmerge-orphans userfetch userpriv usersandbox usersync xattr"

    EBUILD_PHASES: add instprep (bug 671824)
    Whitelist instprep for collect_ebuild_messages, so that it will
    not reject elog messages from the instprep phase like this:
    !!! can't process invalid log file: /tmp/portage/$PF/temp/logging/instprep

Oops!  s/instaprep/instprep/

(Not instant, install!  I had the same problem when reading the patch discussion on the portage-dev list.  Seems I picked up "instaprep" from somewhere and it's confusing me.  Maybe I should have mentioned it then.  Oh, well.)
Comment 4 Zac Medico gentoo-dev 2019-04-10 04:32:38 UTC
Fixed in portage-2.3.62.
