Bug 52506 – Portage fails to block a default virtual even if a different providing package is installed

• Status: RESOLVED FIXED
• Product: Portage Development

[Description Grant Goodyear (RETIRED) 2004-05-30 17:22:26 UTC]

By default, virtual/mta is mail-mta/ssmtp.  After installing postscript I
really want ssmtp to be blocked if "mailwrapper" is not in USE.  Unfortunately,
portage seems to allow ssmtp to be merged if it is defined as a virtual:

# USE="-mailwrapper" emerge =postfix-2.0.19-r3 
# USE="-mailwrapper" emerge =ssmtp-2.60.7-r1 -vp
 
These are the packages that I would merge, in order:
 
Calculating dependencies ...done!
[ebuild  N    ] mail-mta/ssmtp-2.60.7-r1  -ipv6 -mailwrapper -md5sum +ssl 0 kB

# python -c 'import portage; print portage.settings.virtuals["virtual/mta"]'
['mail-mta/postfix', 'mail-mta/ssmtp']

# ( . /usr/portage/mail-mta/ssmtp/ssmtp-2.60.7-r1.ebuild && echo ${RDEPEND} )
-bash: inherit: command not found
mailwrapper? ( >=net-mail/mailwrapper-0.2 ) !mailwrapper? ( !virtual/mta ) net-mail/mailbase ssl? ( dev-libs/openssl )

# sed -ie '/ssmtp/d' /etc/make.profile/virtuals
# USE=-mailwrapper emerge =ssmtp-2.60.7-r1 -vp                                                                                 
These are the packages that I would merge, in order:
 
Calculating dependencies ...done!
[blocks B     ] mail-mta/postfix (from pkg mail-mta/ssmtp-2.60.7-r1)
[ebuild  N    ] mail-mta/ssmtp-2.60.7-r1  -ipv6 -mailwrapper -md5sum +ssl 0 kB

It gets even weirder.  I should have stopped when I thought I'd solved the
problem.

# cd /etc/make.profile && rm virtuals && cvs up virtuals

# sed -ie 's/ssmtp/sendmail/' /etc/make.profile/virtuals
# python -c 'import portage; print portage.settings.virtuals["virtual/mta"]'
['mail-mta/postfix', 'mail-mta/sendmail']

# USE=-mailwrapper emerge =ssmtp-2.60.7-r1 -vp
 
These are the packages that I would merge, in order:
 
Calculating dependencies ...done!
[ebuild  N    ] mail-mta/ssmtp-2.60.7-r1  -ipv6 -mailwrapper -md5sum +ssl 0 kB

# sed -ie '/sendmail/d' /etc/make.profile/virtuals
# python -c 'import portage; print portage.settings.virtuals["virtual/mta"]'
['mail-mta/postfix']
# USE=-mailwrapper emerge =ssmtp-2.60.7-r1 -vp                                                                                 
These are the packages that I would merge, in order:
 
Calculating dependencies ...done!
[blocks B     ] mail-mta/postfix (from pkg mail-mta/ssmtp-2.60.7-r1)
[ebuild  N    ] mail-mta/ssmtp-2.60.7-r1  -ipv6 -mailwrapper -md5sum +ssl 0 kB

Okay, that's really weird!

s/postscript/postfix/g

[Comment 2 Grant Goodyear (RETIRED) 2004-05-30 17:36:14 UTC]

I should also add that the postfix and ssmtp versions I referenced (and
the sendmail version as well) are all package.mask'd, w/ corresponding
entries in /etc/portage/package.unmask.

[Comment 3 Nicholas Jones (RETIRED) 2004-06-05 16:08:20 UTC]

If I had to guess I'd say it's substituting in for the blocker incorrectly.

[Comment 4 Masatomo Nakano (RETIRED) 2004-06-20 00:04:58 UTC]

Fixed in CVS.

(It happens when there are two or more packages in one virtual varibale.)

[Comment 5 Nicholas Jones (RETIRED) 2004-10-22 08:48:02 UTC]

Bug has been fixed and released in stable portages on or before 2.0.51-r2
