Function Details

[hide private]

GetUid(user, _getpwnam)

source code

Retrieve the uid from the database.

Parameters:

user (string) - The username to retrieve

Returns:

The resolved uid

GetGid(group, _getgrnam)

source code

Retrieve the gid from the database.

Parameters:

group (string) - The group name to retrieve

Returns:

The resolved gid

GetEnts(resolver=GetentResolver)

source code

Singleton wrapper around resolver instance.

As this method is accessed by multiple threads at the same time we need to take thread-safety carefully.

InitArchInfo()

source code

Initialize architecture information.

We can assume this information never changes during the lifetime of a process, therefore the information can easily be cached.

Note: This function uses platform.architecture to retrieve the Python binary architecture and does so by forking to run file (see Python documentation for more information). Therefore it must not be used in a multi-threaded environment.
