NAME

urpm::orphans - The orphan management code for urpmi  

SYNOPSIS

 

DESCRIPTION

unrequested_list__file($urpm)
Return the path of the unrequested list file.
unrequested_list($urpm)
Returns the list of potentiel files (ake files installed as requires for others)
mark_as_requested($urpm, $state, $test)
Mark some packages as explicitly requested (usually because they were manually installed).
_installed_req_and_unreq($urpm)
Returns :
req: list of installed packages that were installed as requires of others
unreq: list of installed packages that were not installed as requres of others (ie the ones that were explicitely selected for install)
_installed_and_unrequested_lists($urpm)
Returns :
pkgs: list of installed packages
unrequested: list of packages that were installed as requires of others (the sum of the previous lists)
_installed_req_and_unreq_and_update_unrequested_list ($urpm)
Returns :
req: list of installed packages that were installed as requires of others
unreq: list of installed packages that were not installed as requres of others (ie the ones that were explicitely selected for install)
unrequested: list of packages that were installed as requires of others (the sum of the previous lists)
_selected_unrequested($urpm, $selected, $rejected)
Returns the new ``unrequested'' packages. The reason can be ``required by xxx'' or ``recommended''
_renamed_unrequested($urpm, $selected, $rejected)
Returns the packages obsoleting packages marked ``unrequested''
check_unrequested_orphans_after_auto_select($urpm)
We don't want to check orphans on every auto-select. We do it only after many packages have been added.

Returns whether we should look for orphans depending on a threshold.

unrequested_orphans_after_remove($urpm, $toremove)
This function computes whether removing $toremove packages will create unrequested orphans.

It does not return the new orphans since ``whatrecommends'' is not available,

If it detects there are new orphans, _all_unrequested_orphans() must be used to have the list of the orphans

_will_package_be_unneeded($urpm, $db, $toremove, $pkg)
Return true if $pkg will no more be required after removing $toremove

nb: it may wrongly return false for complex loops, but will never wrongly return true

_will_prop_still_be_needed($urpm, $db, $toremove, $fullname, $prop, $required_maybe_loop)
Return true if $prop will still be required after removing $toremove
_get_current_kernel_package()
Return the current kernel's package so that we can filter out current running kernel:
_kernel_callback ($pkg, $unreq_list)
Returns list of kernels

_fast_ version w/o looking at all non kernel packages requires on kernels (like ``urpmi_find_leaves '^kernel''' would)

_all_unrequested_orphans blacklists nearly all kernels b/c of packages like 'ndiswrapper' or 'basesystem' that requires 'kernel'

rationale: other packages only require 'kernel' or a sub package we do not care about (eg: kernel-devel, kernel-firmware, kernel-latest) so it's useless to look at them

_get_orphan_kernels()
Returns list of orphan kernels
_all_unrequested_orphans($urpm, $req, $unreq)
Returns the list of ``unrequested'' orphans.
compute_future_unrequested_orphans($urpm, $state)
Compute the list of packages that will be unrequested and could potently be removed.
get_orphans($urpm)
Returns the list of unrequested packages (aka orphans).

It is quite fast. the slow part is the creation of $installed_packages_packed (using installed_packages_packed())

get_now_orphans_gui_msg($urpm)
Like get_now_orphans_msg() but more suited for GUIes, it return message about orphan packages.

Used by rpmdrake.

get_now_orphans_msg($urpm)
Similar to get_now_orphans_gui_msg() but more suited for CLI, it return message about orphan packages.
add_leading_spaces($string)
Add leading spaces to the string and return it.
