[gentoo-portage-dev] Portage persistence structures :: information about ports tree
Hi. I'm reading portage docs and sources at /usr/lib/portage trying to understand how portage persists information on 'available ports'. So, I'm reading /usr/lib/portage/bin/emerge: --- snip --- portdb = trees[porttree].dbapi --- snip --- Where 'trees' is a parameter to 'search's object construction. But who really uses 'search class' is 'action_search' as we can see below: --- snip --- def action_search(settings, trees, myopts, myfiles, spinner): [...] searchinstance = search(settings, trees, spinner, --searchdesc in myopts, --quiet not in myopts, --usepkg in myopts, --usepkgonly in myopts) [...] --- snip --- Later in 'emerge' file we have --- snip --- action_search(settings, trees[settings[ROOT]], --- snip --- ... and so on ... I'm trying to track the calls, instantiations, etc to figure out how portage persists ports info. May someone give me some help on this ? How does portage do the searchs ? Walk into the ports tree and build some structure or store this info on some embedded database like berkeley db or sqlite ? Thanks in advance. -- João Macaíba [EMAIL PROTECTED] -- gentoo-portage-dev@lists.gentoo.org mailing list

You're probably looking for the portdbapi class defined in pym/portage.py (or pym/portage/dbapi/porttree.py in 2.2), in particular the cp_all(), cpv_all(), cp_list() and aux_get() methods. Marius Thanks very much, Marius, for you help/time ! :) I'll take a look at them. Best regards. -- João Macaíba [EMAIL PROTECTED] -- gentoo-portage-dev@lists.gentoo.org mailing list

Marius I think for searching you may find the xmatch function to be a very versatile and useful tool. I think it is one of the more used functions that porthole uses from portage.
