merge_group(groupA, groupB)

source code

Merges two removal groups into one

Note that some values are taken entirely from groupA (e.g. name and message)

Parameters:

groupA (dict) - A removal group
groupB (dict) - Another removal group

Returns: dict

A merged group

auto_decruft_suite(suite_name, suite_id, session, dryrun, debug)

source code

Run the auto-decrufter on a given suite

Parameters:

suite_name (string) - The name of the suite to remove from
suite_id (int) - The id of the suite denoted by suite_name
session (SQLA Session) - The database session in use
dryrun (bool) - If True, just print the actions rather than actually doing them
debug (bool) - If True, print some extra information

sources2removals(source_list, suite_id, session)

source code

Compute removals items given a list of names of source packages

Parameters:

source_list (list) - A list of names of source packages
suite_id (int) - The id of the suite from which these sources should be removed
session (SQLA Session) - The database session in use

Returns: list

A list of items to be removed to remove all sources and their binaries from the given suite

decruft_newer_version_in(othersuite, suite_name, suite_id, rm_msg, session, dryrun, decruft_equal_versions)

source code

Compute removals items given a list of names of source packages

Parameters:

othersuite (str) - The name of the suite to compare with (e.g. "unstable" for "NVIU")
suite (str) - The name of the suite from which to do removals (e.g. "experimental" for "NVIU")
suite_id (int) - The id of the suite from which these sources should be removed
rm_msg (str) - The removal message (or tag, e.g. "NVIU")
session (SQLA Session) - The database session in use
dryrun (bool) - If True, just print the actions rather than actually doing them
decruft_equal_versions (bool) - If True, use >= instead of > for finding decruftable packages.
