rosclean: simplifying run-time dependencies When roslaunch is started, it checks the file size of the local log directory by calling: disk_usage = rosclean.get_disk_usage(d) [1] The function `get_disk_usage` [2] in rosclean creates a subprocess and calls `du -sb` on Linux systems (cf. [3]). However, the `du` command, which busybox usually provides on an embedded Linux image, does not support the `-b` option, and only the `du` command from the coreutils [4] supports this option. This issue was first reported in April 2013 on the meta-ros issue tracker [5]. Hence, on the first iteration of this issue, the commit db0c8d5c [6] simply adds the dependency on coreutils to roslaunch. However, this has certain disadvantages: - coreutils is licensed under GPLv3 and must not be deployed in a product, which is massively distributed to customers. - coreutils has larger file-system foot print than busybox and makes the minimal Linux images considerably larger. As a fortuitous circumstance, Alexis Ballier [7] had already observed this disadvantage and provides a patch [8, 9] that makes `get_disk_usage` use `du -k`, which works with busybox and coreutils. So, on the second iteration of this issue, this commit here patches rosclean's `get_disk_usage` function with the aforementioned patch. This slightly modifies the semantics of this function. However, I believe this plays only a minor role for the overall intended functionality to check if the log usage has reached a critical file-size limit, and it allows us to remove the dependency on coreutils, which is much more critical. Andreas Baak reported the disadvantages of the previous solution, which triggered the re-investigation. The current resolution has been discussed and worked out in collaboration with Andreas Baak.
