 Posted: Thu Oct 11, 2012 10:47 am Post subject: Cannot understand enalyze |
 |
|
I'm trying to understand the enalyze tool from gentoolkit, just to be sure if it can be useful for administering my Gentoo Linux system, but have some doubts.
For example, when running "enalyze rebuild --pretend use", I get the following result:
| Code: | -- Scanning installed packages for USE flag settings that
do not match the default settings
-- These are the installed packages & use flags that were detected
to need use flag settings other than the defaults.

As you can see there are a lot of packages with the introspection (red) USE flag. As far as I understand this means that the introspection USE flag was enabled by me somewhere because it's not a default Portage setting. Instead I never enabled it myself, because I don't even know what introspection is and if I need it, so I prefer to stick to defaults.
Also, I don't understand the difference between the "use" and the "pkguse" targets for the "analyze" module. It seems both analyze USE flags, but in which way they differ?
Thank you. |

The one thing that the rebuild module does not do is look at the current ebuild and remove any defaulted USE flag settings. That is most likely where the discrepancy comes from. The rebuild module gets all it's info from portage up to but not including any /etc/portage/package.use settings. So that would include any ebuild defaulted flags. To see if the flags in question are defaulted in the ebuild. You need to look at the IUSE value in the ebuild or the IUSE value in /var/db/pkg/{cat}/{pkg-ver}/IUSE
for ex: | Code: | brian@big_daddy ~/Dev/git/gentoolkit $ cat /var/db/pkg/app-accessibility/at-spi2-core-2.2.3/IUSE
doc +introspection |
This shows the introspection USE flag defaulted from the ebuild.
Also ebuild defaulted flags can be overridden in /etc/portage/package.use, not in make.conf's USE=
The difference between:
use (/var/db/pkg/{cat}/{pkg-ver}/USE)
and
pkguse (/var/db/pkg/{cat}/{pkg-ver}/PKGUSE)
is that use is the final installed setting of the enabled flags while pkguse is the recorded settings from /etc/portage/package.use at the time of the merge. Looking at the report just now, I think I made a mistake in how it is processed. It isn't matching a sample I was just using as a check. I"ll have to look into it more. For now just stick with "use"
So, thank you for that, I should add an option to remove any ebuild defaulted flags from the rebuild list created.
