Bug 39221 – virtuals cause self-blockage in portage-2.0.50-pre19

• Status: RESOLVED FIXED
• Product: Portage Development

[Description Jeff Ames 2004-01-23 20:04:21 UTC]

e.g. qmail blocks itself, because it depends on !virtual/mta, which it provides.

# emerge -p qmail --debug

These are the packages that I would merge, in order:

Calculating dependencies  
Parent:    None
Depstring: net-mail/qmail
Candidates: ['net-mail/qmail']
ebuild: net-mail/qmail-1.03-r15

Parent:    ebuild / net-mail/qmail-1.03-r15 merge
Depstring: virtual/glibc sys-apps/groff ssl? ( >=dev-libs/openssl-0.9.6g ) >=net-mail/queue-fix-1.4-r1 !bootstrap?

Candidates: ['!virtual/mta']                                                                                   Exiting... ebuild / net-mail/qmail-1.03-r15 merge
Exiting... None                                                                                                ...done!
[blocks B     ] net-mail/qmail ("virtual/mta" from pkg net-mail/qmail-1.03-r15)
[ebuild   R   ] net-mail/qmail-1.03-r15  

I would guess this is related to the change in emerge around line 708 (at least, replacing this section with that from portage-2.0.50-pre16 makes this problem go away, while conflicting packages (e.g. ssmtp) still are properly blocked), though I don't know the code well enough to say for sure.

This also happens with other virtuals, like bittorrent and tetex, though seemingly not with ones that aren't exclusive.

I already fixed it in CVS.
I hope it will be released soon..

supposed to be fixed in 2.0.50 which is stable now. If this bug is not fixed please reopen.
