Allocator and error handling in c utilities #16

wjwwood · 2017-04-12T07:57:08Z

This should help with ros2/rmw#94 and #6.

Pull requests to remove the duplicate functionality in rmw and rcl will follow, but the pr for gmock (ament/ament_cmake#91) can be merged at anytime.

I tried to take care to have a "move" commit and then a "change" commit.

wjwwood · 2017-04-12T08:00:49Z

I still haven't figure out what to do with the memory tools that have been copied here. They are also used in rcl even after removing the allocator stuff later. I don't really want to create a new package for it, so I might expose the source files from this repository via a cmake macro, since they're useful for testing C or C++ in other packages.

Why are the existing unmodified gtests changed into gmocks?

I thought I should only use gmock or gtest, but not both. I can change them back if that's not the case.

I never heard back from you on this, so I just did it anyways as not to delay this further: 3d746c0

wjwwood · 2017-04-15T01:21:08Z

With respect to how to de-duplicate the memory_tools here and in rcl, I will address this in a follow on pull request after we do the renaming (#17). For two reasons, first I want to merge these pr's before doing the renaming and de-duplicating memory_tools is going to take a lot of time, and second because I want to refactor memory tools even more to be namespaced under this package's name and I'd rather not do it twice.

This looks good, mostly nitpick at this point. I'll try to review this more thoroughly tomorrow. Thanks for pounding on this

should this use SAFE_FWRITE_TO_STDERR like the other error messages?

or simply fwrite like above to be consistent

This error message uses formatting (like %s), fwrite cannot do that. I only fallback to fwrite when memory allocation fails, because apparently it can still work on some systems even when malloc fails.

maybe you meant:

if(error_string_ptr) { char * error_string = *error_string_ptr; if(error_string) {

I think so, I guess it was wrong in rmw as well.

what happens if allocator is null? wouldnt deallocate not be defined?

error_state_ptr may be null, but error_state_ptr->allocator cannot be null. error_state_ptr->allocator->deallocate can be null though. The assumption is (and I think it holds) that if error_state_ptr is not null, then the allocator will be valid as well. I can make it more defensive though.

nit: should thi be included as system header?

Some of the other files are combining it with the system headers, but it's not a system header imo, i.e. it's not part of the standard library. So I don't think so, but I can I guess.

I'm not sure about the issues on macOS, because I cannot reproduce them locally. I wasn't getting those errors until very recently. I'll look into it before merging.

Looks like something is amiss with mini1, dosa reports green for macOS:

The same for all the prefixes in the memory_tools.hpp.

Thanks for catching that, see: #24
