[gentoo-dev] emerge resume list

[gentoo-dev] emerge resume list

[evader]

Hi,

I'm not sure if this is the correct list to send this too, but it is the  
only gentoo one I am currently subscribed to.

When I do an emerge -e world where is the list of files to be merged  
stored? For example if I break an emerge, and want to resume later from a  
different position, can I edit the packages to be emerged list so I don't  
have to do emerge --resume --skipfirst constantly?

Thanks,

evader

The list is stored in a small database file in /var/cache/edb/mtimedb

It is a binary file full of pickled python objects.  I was actually
poking around it and thought about writing a tool.  I will commit more
time to it if you are interested; although be warned that editing things
in that file is not particularly recommended.  The dependency resolution
 for the packages in the list is done and the list is created.  Removing
items from it could cause packages to not build, and the dependency tree
to essentially be broken for that list.

Also, portage questions are generally well received at
gentoo-portage-dev@gentoo.org, or on IRC: irc.freenode.net #gentoo-portage.

Thanks for your prompt response.

It would be very useful I think to have a small tool to continue a merge  
 from a certain point, for example by selecting the package name you want  
to continue from.

Example:  eresume dev-db/mysql

Would just look in the /var/cache/edb/mtimedb file for 'dev-db/mysql' and  
continue.

It could be an emerge feature:

Example: emerge --resume --from dev-db/mysql

I might look in to coding something.

Thanks.

Hi,

Further to my email before, a quick hack in the emerge script somewhere  
here should fix it:
# We're resuming.
                         print green("*** Resuming merge...")
                         emergelog(" *** Resuming merge...")
                         mymergelist=portage.mtimedb["resume"]["mergelist"][:]
                         if ("--skipfirst" in myopts) and mymergelist:
                                 del  
portage.mtimedb["resume"]["mergelist"][0]
                                 del mymergelist[0]
                         for bigkey in mymergelist:
                                 (pkgtype, root, cpv, action) = bigkey
                                 if pkgtype == "binary" and not  
portage.db["/"]["bintree"].dbapi.match("="+cpv) or \
                                    pkgtype == "ebuild" and not  
portage.db["/"]["porttree"].dbapi.xmatch("match-all", "="+cpv):

This is the first time I've looked at so I'll see how I go. Any tips?

Useful as this may seem, having to "do do emerge --resume --skipfirst
constantly" implies that that you need to clean out dependencies of 
packages you once used and then unmerged, or that your system is
broken on a more basic level. Skipping packages that fail leaves the
unneeded, probably broken older builds in place and may cause
other packages to (partly) not build as well, and so on.


Kind regards,

I have a script (attached) that, more or less does the --skipfirst
automatically.  You may need to change it to suit your tastes.
