[gentoo-dev] Concurrent download and merge

[Nick Jones]

I've been working on code to make downloading occur continuously
during the emerge process. I have new, clean, and working code
that needs a bit more testing that I can give it. I'd appreciate
some testing. It includes a couple subtle enhancements also. Try
'emerge -ef world' to see the "(X of Y)" counts.

At present, the output is a little noisy because wget and builds
are happening at the same time. I HIGHLY recommend adding "-q"
to wget's FETCH_COMMAND in make.globals/make.conf.

Please CC me (carpaski@g.o) with any bugs that you think
you come across. PLEASE follow the directions in the README.txt.

It does as follows:

1. Downloads begin and do not pause until they are completed.
2. Merges occur in order as the required files finish downloading.
3. Failed merges will stop the merging of packages at that point,
   but fetching will continue until all files are downloaded.
4. Failed fetches will be announced, but WILL NOT stop the fetching.
   Merges will continue until the failed fetch is reached. Fetches
   will continue until all fetches have completed.
5. Failures in the fetching and/or failure in the merge will be
   noted when both the fetching and the merging are completed.
   Only one notice for the fetches is given. Only one notice
   of the failed merge is given.

Thanks,
