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: i(t PER_INSTANCE(tutiltubuntutdebians+/etc/apt/apt.conf.d/90cloud-init-pipeliningsQ//Written by cloud-init per 'apt_pipelining' Acquire::http::Pipeline-Depth "%s"; cCstj|dd}t|jj}|dkrLtd|tna|d kr\dS|gtddD]}t|^qokrt||tn|jd |dS( Ntapt_pipeliningtostfalset0tnonet unchangediis%Invalid option for apt_pipelining: %s(RR sos( Rtget_cfg_option_strtstrtlowertstriptwrite_apt_snippett DEFAULT_FILEtrangetwarning(t_nametcfgt_cloudtlogt_argstapt_pipe_valuetapt_pipe_value_stb((sF/usr/lib/python2.7/site-packages/cloudinit/config/cc_apt_pipelining.pythandle2s  .cCs1t|}tj|||jd||dS(s0Writes f_name with apt pipeline depth 'setting'.s+Wrote %s with apt pipeline depth setting %sN(t APT_PIPE_TPLRt write_filetdebug(tsettingRtf_namet file_contents((sF/usr/lib/python2.7/site-packages/cloudinit/config/cc_apt_pipelining.pyRAs N( t__doc__tcloudinit.settingsRt cloudinitRt frequencytdistrosRRRR(((sF/usr/lib/python2.7/site-packages/cloudinit/config/cc_apt_pipelining.pyts   ? l ?# Copyright 2014 Eucalyptus Systems, Inc. # # Redistribution and use of this software in source and binary forms, # with or without modification, are permitted provided that the following # conditions are met: # # Redistributions of source code must retain the above copyright notice, # this list of conditions and the following disclaimer. # # Redistributions in binary form must reproduce the above copyright # notice, this list of conditions and the following disclaimer in the # documentation and/or other materials provided with the distribution. # # THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS # "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT # LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR # A PARTICULAR PURPOSE ARE DISCLAIMED.
