Description Masatomo Nakano (RETIRED) gentoo-dev

I tested revdep-rebuild and I've found a bug.

I did
# revdep-rebuild  --soname libpq.so.3


then I debuged.
It caused REBUILD_GREP='^\()$'

I debuged more..

It is the cause. The package is maskd.

emerge --nospinner --pretend --oneshot --nodeps $RAW_REBUILD_LIST

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

Calculating dependencies
!!! all ebuilds that could satisfy "=dev-libs/libpq++-4.0" have been masked.

!!! Error calculating dependencies. Please correct.

Sorry, I forgot the error message.

This is error message.

Please copy contents of /root/.revdep-rebuild_23e5b2d4.3_rebuild as an attachment.

Comment 4 Stanislav Brabec 2003-07-01 09:33:57 UTC

Oops, now I see reason - portage rejects to merge it, so revdep-rebuild cannot resolve order.

Please try ACCEPT_KEYWORDS='~x86' revdep-rebuild ...

The bug is probably more general - if package is not longer in portage or it is hardmasked, revdep-rebuild fails. There is no simple solution for it, but it can at least do a order-ambiguous rebuild.

I see...

But if there is no simple solution for it, I think it should say 
error messages in order that a user may not get confused.

Comment 6 Stanislav Brabec 2003-07-01 12:23:10 UTC

There is a simple work around - if order resolving fails, try to recompile packages in "random" order - for most cases it works. I will look for such "fix".

revdep-rebuild

There is a quick fix. I have not tested it yet for syntax, but it should check
for exit status of emerge, and if it fails, ignore its output.

Comment 8 Stanislav Brabec 2003-07-09 09:50:10 UTC

While fixing, I have also find another bug of this code - it sometimes forgets to recompile package. While analyzing following text:

[ebuild   R  ] gnome-extra/at-poke-0.1.0-r1
[ebuild    UD] gnome-extra/at-spi-1.0.2 [1.1.8]

it does not properly analyze [expression] at the end of second line.

Both bugs are now fixes in portage tree.
