I was testing it earlier again my Perl dependency checker that I'm working on. |
| 13 |
After deleting the contents of /var/cache/edb/dep, Portage took 42s to do |
| 14 |
'emerge -ep xfree'. It then took 2.819s to run the same command again with the |
| 15 |
cache rebuilt. My program took 0.981s to do the same thing while generating |
| 16 |
dependency information directly from the ebuilds on the fly. Although, my |
| 17 |
dependency checker isn't yet as complete as Portage's. |
| 18 |
|
| 19 |
For example, if one package has a dependency of '>=package2-2.0' and another has |
| 20 |
'<package2-2.3' and the newest version of package2 is 2.6, my program will |
| 21 |
choose to install package2-2.6. |
| 22 |
|
| 23 |
It can currently handle USE flags, auto-USE flags, (un)masked packages, and |
| 24 |
virtuals (somewhat). It also saves time by not involving bash in the dependency |
| 25 |
process at all. Instead, it parses all the variable declarations straight out of |
| 26 |
the ebuild and does bash-style interpolation within the program. |
