I've done some hacking (okay, ugly hacking) with portage lately. |
| 2 |
reading some source and trying to get a grasp at the code. so far |
| 3 |
I've only patched 'dep_bestmatch' to deal with stability-symlinks in |
| 4 |
the portage tree. |
| 5 |
|
| 6 |
this is what the patch actually does: |
| 7 |
|
| 8 |
almach freeciv # PORTAGE_LEVEL="STABLE" emerge --pretend freeciv |
| 9 |
These are the packages that I would merge, in order. |
| 10 |
Calculating dependencies ...done! |
| 11 |
[ebuild N ] app-games/freeciv-1.12.0-r1 to / |
| 12 |
|
| 13 |
almach freeciv # emerge --pretend freeciv |
| 14 |

| 16 |
[ebuild N ] app-games/freeciv-1.12.0-r2 to / |
| 17 |
|

notice that last symlink. :) |
| 29 |
|
| 30 |
this is against 1.9.1, I haven't even looked at any other version of |
| 31 |
portage. |
| 32 |
|
| 33 |
now, I don't expect this to get anywhere near the main tree. don't |
| 34 |
worry about that. :) |
| 35 |
|
| 36 |
I am however curious to how what people think of the idea, and the |
| 37 |
implementation. it probably shows that I haven't coded python in a |
| 38 |
year or so. and no, this hasn't been tested overly much, just |
| 39 |
enough for me to feel that it apparently "works for me". please, |
| 40 |
thump me over the head if there is a reason to do so. |
| 41 |
|
| 42 |
I know some people want a package.mask to do separate stable |
| 43 |
releases, and they probably know I don't like that one bit. |
| 44 |
personally, I'm going to take a snapshot of my now stable system |
| 45 |
using this scheme. all I need to do is to make a |
| 46 |
"<package>-sysok"-symlink for each installed package. this should |
| 47 |
also hopefully allow me to do rollbacks if I need to do so. |
| 48 |
|
| 49 |
if anyone is wondering on the status of the update-flags I also |
| 50 |
want, well, that'll need quite a bit more work. it will need to be |
| 51 |
integrated into the datastructure that portage uses to keep track of |
| 52 |
packages internally -- which will take time. |
| 53 |
|
| 54 |
anyhow, the patch. I know, I should patch against the portage |
| 55 |
sourcecode directly. but still. :) |
