portage.util.mtimedb module

class portage.util.mtimedb.MtimeDB(filename)

Bases: dict

The MtimeDB class is used to interact with a file storing the current resume lists. It is a subclass of dict and it reads from/writes to JSON, by default, althouth it can be configured to use pickle.

__write_to_disk(d)

Private method used by the commit method.

_json_write = True

_json_write_opts = {'ensure_ascii': False, 'indent': '\t', 'sort_keys': True}

_load(filename)

clear() → None.  Remove all items from D.

commit()

copy() → a shallow copy of D

fromkeys(value=None, /)

Create a new dictionary with keys from iterable and values set to value.

get(key, default=None, /)

Return the value for key if key is in the dictionary, else default.

property is_readonly

items() → a set-like object providing a view on D's items

keys() → a set-like object providing a view on D's keys

make_readonly()

pop(k[, d]) → v, remove specified key and return the corresponding value.

If the key is not found, return the default if given; otherwise, raise a KeyError.

popitem()

Remove and return a (key, value) pair as a 2-tuple.

Pairs are returned in LIFO (last-in, first-out) order. Raises KeyError if the dict is empty.

setdefault(key, default=None, /)

Insert key with a value of default if key is not in the dictionary.

Return the value for key if key is in the dictionary, else default.

update([E, ]**F) → None.  Update D from dict/iterable E and F.

If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]

values() → an object providing a view on D's values
