# update_psa
|
|
||||||
#
|
|
||||||
# Implementing the UpdateController (see below). UpdateController is waiting
|
|
||||||
# for an external trigger by the DeviceController (DC). The trigger is sent via
|
|
||||||
# an UNIX-pipe (=fifo). When DC triggers UpdateController, it has to check if
|
|
||||||
# an update is possible, i.e. is has to lock the PSA for the update procedure.
|
|
||||||
# UpdateController will send back the update-result to DeviceController
|
|
||||||
# which unlocks the PSA to return to nomal operation.
|
|
||||||
#
|
|
||||||
# If UpdateController has been triggered, it checks out a predefined git-
|
|
||||||
# repository. As a sanity check it makes sure that there are some changes in
|
|
||||||
# the repository. In case there are no changes, it issues an error message
|
|
||||||
# to DC and returns to its wait-state.
|
|
||||||
#
|
|
||||||
# Otherwise it checks if the changed files are correct (using md5) and if
|
|
||||||
# the new files are valid for the PSA. If there is some problem, it issues an
|
|
||||||
# error message to DC, reverts the git-repository to its previous state and
|
|
||||||
# returns to its wait-state.
|
|
||||||
#
|
|
||||||
# Otherwise it makes a backup of the current state of the PSA, and if there
|
|
||||||
# are opkg-packages to install it runs a dry installation process using opkg.
|
|
||||||
# In case of error, it issues an error message to DC, deletes the backup,
|
|
||||||
# reverts # the git-repository to its previous state and returns to its
|
|
||||||
# wait-state.
|
|
||||||
#
|
|
||||||
# Otherwise, it copies all new files to their target locations and in case
|
|
||||||
# of opkg-packages, it installs the packages.
|
|
||||||
#
|
|
||||||
# In case of error it restores the previous state using the backup and
|
|
||||||
# reinstalls the previous opkg-package(s). It issues an error message to
|
|
||||||
# DC and returns to its wait-state.
|
|
||||||
#
|
|
||||||
# Otherwise the update went well, and it does some cleanup, sends a success
|
|
||||||
# message to DC and returns to its wait-state.
