Both must be available in network.\n\nIt is currently not possible to put both on the Hawkbit Server, as SWUpdate expects that they are SWU.\nSWUpdate expects that the URL for the ZCK is set into sw-description, but this is\nhard to reach because the URL is generated by Hawkbit when a file is uploaded, and further\nuploads can modify the URL.\n\nThis series introduce the concept of list of servers where to download artifacts.\nThe Hawkbit Connector will first scan all modules returned by the server, and for files\nof a selected extension (\"rule\"), a specific action is taken. For Hawkbit,\nthe URL of the artifact is stored into0 a list that will be deleted after the update\nhas terminated.\n\nWhen the delta handler is running, if no URL or \"dynamic\" as URL is set, the handler will \ncheck the list and look for an entry set to the value of \"zckfile\" in the properties.\nThis URL is then used for the update.\n\nNote that Hawkbit in the current and tested versions has a bug for multipart messages - this\nis reported to Hawkbit as issue #2918. An additional patch that force the multipart parser\nis sent separately, but it is not planned to be merged as the issue should be solved in Hawkbit.\n\n\nStefano Babic (9):\n hawkbit: move out parsing of artifact\n hawkbit: add rules for incoming artifacts\n Add IPC to send a list of URL as sources\n delta handler: retrieve URL from core if not present\n delta: check if a config file is set before parsing\n delta_downloader: activate ssl as default\n delta_downloader: enable debug of channel\n Factorize function to set authorization token\n delta_downloader: load tokens from configuration\n\n core/installer.c | 5 +\n core/network_thread.c | 17 +++\n core/swupdate.c | 1 +\n corelib/server_utils.c | 19 ++++\n doc/source/handlers.rst | 53 +++++++++\n handlers/delta_downloader.c | 81 +++++++++----\n handlers/delta_handler.c | 22 +++-\n include/network_ipc.h | 7 ++\n include/server_utils.h | 1 +\n include/swupdate.h | 1 +\n include/swupdate_image.h | 1 +\n ipc/network_ipc-if.c | 17 +++\n parser/parser.c | 1 +\n suricatta/server_hawkbit.c | 221 ++++++++++++++++++++++++------------\n suricatta/server_hawkbit.h | 11 ++\n 15 files changed, 360 insertions(+), 98 deletions(-)" }
