- get_backtrace(empty='Empty backtrace.')[source]¶
Try to get backtrace as string. Returns “Error while trying to get backtrace” on failure.
- get_bytes_size(size, unit_name)[source]¶
Converts a unit and a number into a number of bytes.
>>> get_bytes_size(2, 'KB') 2048.0
>>> to_unicode('ascii') == u'ascii' True >>> to_unicode(u'utf\xe9'.encode('UTF-8')) == u'utf\xe9' True >>> to_unicode(u'unicode') == u'unicode' True
Find the path to an executable by its base name (such as ‘gpg’).
The executable can be overriden using an environment variable in the form NAME_EXECUTABLE where NAME is the specified base name in upper case.
If the environment variable is not provided, the PATH will be searched both without and with a “.exe” suffix for Windows compatibility.
If the executable can not be found, None is returned.
- polling_loop(*, count=None, timeout=None, delay=5)[source]¶
Delay iterator for polling loops.
The count or timeout must be specified; both can be simultaneously. The default delay is five seconds.
count (int) – Maximum number of iterations this loop can produce. Can be None for unlimited retries.
timeout (float) – Maximum number of seconds to try the loop for.
delay (float) – Delay in seconds between each iteration.
