It may be useful for pipelining to be disabled, because some web servers, such as S3 do not pipeline properly (LP: #948461). The ``apt_pipelining`` config key may be set to ``false`` to disable pipelining altogether. This is the default behavior. If it is set to ``none``, ``unchanged``, or ``os``, no change will be made to apt configuration and the default setting for the distro will be used. The pipeline depth can also be manually specified by setting ``apt_pipelining`` to a number. However, this is not recommended. **Internal name:** ``cc_apt_pipelining`` **Module frequency:** per instance **Supported distros:** ubuntu, debian **Config keys**:: apt_pipelining: <false/none/unchanged/os/number> i����( t PER_INSTANCE( t utilt ubuntut debians+ /etc/apt/apt.conf.d/90cloud-init-pipeliningsQ //Written by cloud-init per 'apt_pipelining' Acquire::http::Pipeline-Depth "%s"; c C s� t j | d d � } t | � j � j � } | d k rL t d | t � na | d k r\ d S| g t d d � D] } t | � ^ qo k r� t | | t � n | j d | � d S( Nt apt_pipeliningt ost falset 0t nonet unchangedi i s% Invalid option for apt_pipelining: %s( R R s os( R t get_cfg_option_strt strt lowert stript write_apt_snippett DEFAULT_FILEt ranget warning( t _namet cfgt _cloudt logt _argst apt_pipe_valuet apt_pipe_value_st b( ( sF /usr/lib/python2.7/site-packages/cloudinit/config/cc_apt_pipelining.pyt handle2 s .c C s1 t | } t j | | � | j d | | � d S( s0 Writes f_name with apt pipeline depth 'setting'.s+ Wrote %s with apt pipeline depth setting %sN( t APT_PIPE_TPLR t write_filet debug( t settingR t f_namet file_contents( ( sF /usr/lib/python2.7/site-packages/cloudinit/config/cc_apt_pipelining.pyR A s N( t __doc__t cloudinit.settingsR t cloudinitR t frequencyt distrosR R R R ( ( ( sF /usr/lib/python2.7/site-packages/cloudinit/config/cc_apt_pipelining.pyt <module> s
