I just had an occasional failure with an `emerge --world' command; thought I'd mention it here as a possible issue for future improvement. Apparently what happened is that a downloaded tar.gz file turned out corrupt, causing the `emerge --world' to come to an early halt (it was supposed to update dozens of packages). I was able to get further by simply removing the corrupt distfile and re-typing the emerge command. So, my suggestion is that maybe emerge should have some kind of limited "retry" functionality for this particular kind of download problem, even though it is probably quite infrequent. The console printout mentions an HTTP response code "206 Partial Content" which I cannot remember having seen ever before. My version of portage is 2.1.1_pre3-r1. Below is the console printout and my system info. >>> Emerging (22 of 128) media-libs/svgalib-1.9.25 to / >>> Downloading http://distfiles.gentoo.org/distfiles/svgalib-1.9.25.tar.gz --16:42:02-- http://distfiles.gentoo.org/distfiles/svgalib-1.9.25.tar.gz => `/usr/portage/distfiles/svgalib-1.9.25.tar.gz' Resolving distfiles.gentoo.org... 208.67.219.40 Connecting to distfiles.gentoo.org|208.67.219.40|:80... connected.

I suggest something like this (i don't do python programming, so i sortof put this together quickly: if package fails manifest & DO_NOT_REDOWNLOAD_PKGNAME=false do <command to remove distfile> <command to redownload> set DO_NOT_REDOWNLOAD_PKGNAME=true fi basically if the package fails the manifest check, it redownloads it and sets a variavble to not redownload that package again
I think the problem that you describe is solved by the PORTAGE_FETCH_RESUME_MIN_SIZE variable: http://git.overlays.gentoo.org/gitweb/?p=proj/portage.git;a=commit;h=e2983690e7a22d69cb1507b55050438a6ec3d924
