Agreed, remove reference (which might go stale). > On Nov. 4, 2015, 12:48 p.m., Bernd Mathiske wrote: > > 3rdparty/libprocess/3rdparty/stout/include/stout/os/strerror.hpp, line 64 > > <https://reviews.apache.org/r/39005/diff/6/?file=1115248#file1115248line64> > > > > a) This is an obscure reference.

Removed the reference which was both obscure and not very helpful, and in danger of going stale. > On Nov. 4, 2015, 12:48 p.m., Bernd Mathiske wrote: > > 3rdparty/libprocess/3rdparty/stout/include/stout/os/strerror.hpp, line 53 > > <https://reviews.apache.org/r/39005/diff/6/?file=1115248#file1115248line53> > > > > How would str_error run into errors "itself"?

Error scenarios would be (a) an invalid errnum, or (b) a buffer to small to contain the error message from `strerror_r`. For (a) `strerror_r` will still return some error message string so we do not need to do anything. For (b) we would receive a truncated error message string. The buffer size we use "should be big enough" for any conceivable error message. I added a note to the docstring so users are aware of this limitation. In both cases we would receive some string representation of the given `errnum`. I also expanded the comment on the problems <glibc-2.16 has; I believe providing a complete and safe workaround for all possible use cases of this header provides diminishing returns. - Benjamin ----------------------------------------------------------- This is an automatically generated e-mail.
