In portage commit 1789fdf2ee81 (Add @changed-subslot package set) I |
| 2 |
added this: the set of upgradable packages for which the highest visible |
| 3 |
version has a different subslot than the currently installed version. |
| 4 |
|
| 5 |
Updating the entire stage is expensive and unnecessary (since we're |
| 6 |
going to build the latest packages in stage1 and then rebuild everything |
| 7 |
in stage3). |
| 8 |
|
| 9 |
What we definitely do need to update in the original stage3 however, is |
| 10 |
any package that would trigger a subslot rebuild. |
| 11 |
|
| 12 |
For example: gcc links with libmpfr.so from dev-libs/mpfr. mpfr's SONAME |
| 13 |
changes from libmpfr.so.4 (SLOT="0/4") to libmpfr.so.6 (SLOT="0/6"). If |
| 14 |
the seed stage's dev-libs/mpfr is not updated before emerging gcc, gcc |
| 15 |
will link with libmpfr.so.4, but the latest version of dev-libs/mpfr |
| 16 |
will be built and libmpfr.so.6 included into the stage1. Since the old |
| 17 |
libmpfr.so.4 is not included in the stage1, gcc will not work, breaking |
| 18 |
subsequent stage builds. |
| 19 |
|
| 20 |
Our current options to update the seed are too large a hammer (e.g., |
| 21 |
"--update --deep --newuse @world" or "--update --deep --newuse |
| 22 |
--complete-graph --rebuild-if-new-ver gcc") and spend too much time |
| 23 |
updating seed stages for no gain beyond updating only packages for whom |
| 24 |
the subslot has changed. |
