Adding db directory creation to rosbag2_cpp #450

Marwan99 · 2020-07-01T15:21:09Z

Please let me know if you think this functionality should be implemented elsewhere instead of storage implementation.

SteveMacenski · 2020-07-06T19:29:49Z

@Karsten1987 can you review this (if in your domain)? This is blocking some porting efforts and seems relatively small

Karsten1987 · 2020-07-07T16:45:26Z

thanks a lot for picking this up. However, I think this logic makes more sense within rosbag2_cpp, as we're already dealing with file paths in there and take certain assumptions.

what happens if the directory exists already?

I think the logic should be inverted here: There should be an exception being raised the moment the directory exists already. That's the current behavior in ros2bag. Simply because we don't want to overwrite any files.

That makes sense, should be changed now.

why not using base_folder_? That should avoid the need to verify the parent_path of it.

Sorry for the radio silence, just picked it back again today.

Karsten1987

This looks good to me.

I think you'd need to address the resulting test failures though as well, mainly the tests within rosbag2_cpp, but I have seen other packages fail as well, i.e. rosbag2_tests.
You can verify the tests with colcon test --packages-select-regex rosbag2.

Karsten1987 · 2020-07-14T23:02:08Z

Thinking a bit more about this, I would assume we have to delete the logic within ros2bag here as this would conflict directly with the logic in this PR.

@Karsten1987 ready for review

Karsten1987

Thanks, this looks already quite good. One more round of small comments inline.

I actually think that this should be remove_all in case the directory is not empty.

why this change? Same below

These tests were failing and that fix gave me a placebo of fixing the root cause, apparently the issue was somewhere else. Double checked local and that is not needed anymore, should be reverted back now.

Marwan99 · 2020-07-21T00:09:46Z

Just curious, why is the CI not happy with rcpputils::fs::remove_all? Is it using a cached or released version of rcpputils?

Karsten1987 · 2020-07-21T00:25:01Z

the remove_all functionality is not yet released into rolling. It is present on the current master branches though, so when we trigger CI on ci.ros2.org it won't be failing.

Sure, just to confirm I will need to force push after rebasing. Is that okay?
