While this change was seamless for all rsync users, we developers (at |
| 12 |
least I) got in a bit tricky situation. I'd like to share how I solved |
| 13 |
the problem of "missing" packages on my non-main development boxes now. |
| 14 |
Maybe someone has already developed a better approach. |
| 15 |
|
| 16 |
I decided that since the svn tree is no longer complete, I had to use it |
| 17 |
as overlay on top of a "complete" tree. Hence, I unset my SYNC, moved |
| 18 |
away my PORTDIR and ran emerge --sync to just get an rsync checkout of |
| 19 |
the Prefix tree. Next I added the svn tree to my PORTDIR_OVERLAY |
| 20 |
variable (in etc/make.conf), and found that repoman did not like this |
| 21 |
overlay because of a missing licenses and profiles dir. For licenses I |
| 22 |
just made a symlink to the rsync copy, profiles cannot be a symlink, as |
| 23 |
Portage doesn't like it when two overlays have the same repo_name. So |
| 24 |
what I did instead is to copy the profiles dir from rsync to my svn |
| 25 |
tree, modify the repo_name to have something else. Now that seems to |
| 26 |
work. It should eventually get much better as less and less packages |
| 27 |
are in the "overlay", and we benefit more and more from the metadata |
| 28 |
cache from the rsync tree. Anyway, to keep the profiles dir up-to-date |
| 29 |
in my svn tree, I now use a script with the following in my |
| 30 |
etc/portage/postsync.d: |
| 31 |
|
| 32 |
rsync --exclude=repo_name -a --delete \ |
| 33 |
${EPREFIX}/usr/portage/profiles/ \ |
| 34 |
${EPREFIX}/usr/portage-svn/profiles/ |
| 35 |
pushd ${EPREFIX}/usr/portage-svn > /dev/null |
| 36 |
svn update |
| 37 |
popd > /dev/null |
| 38 |
|
| 39 |
where my svn tree is called "portage-svn", and the regular rsync tree is |
| 40 |
in the standard place. I also just svn up my svn tree, so basically my |
| 41 |
emerge --sync does the full job and I can now do the basic things like |
| 42 |
fixing packages, keywording etc. For profiles changes I just have to |
| 43 |
ssh to my main development box where I have lots of symlinks to retain a |
| 44 |
quasi-full tree. |
| 45 |
|
| 46 |
Hope this is useful for anyone. If there are better ideas to do things |
| 47 |
here, I'm all ears. |
