Hello Hal, thanks for updating the patch! I had it on my todo list during my vacation (still one week left) and didn't have the time to care about it before.
What do you think about the patch below on top of your updated patch? (So far I only tested if it compiles at all.) From: Bernd Schubert <[email protected]> When the partition config file is parsed, partitions are created for each line. If one of the config lines has an error a default partition is created already by a previous commit, but partitions from previous lines are not cleaned up. Avoid this by doing a dry-run parse first and only if this succeeds actually create new partitions. This still ignores errors from osm_prtn_make_new(), but these errors are rather unlikely (i.e. malloc fails) and not really related to the config file.
