Heya - I added an attempt at this on the following branch:

One thing I noticed - in test_util_format.c there is a macro to define htonll:

#if !defined(HAVE_HTONLL) && !defined(htonll)
#define htonll(x) (x)
static uint64_t
htonll(uint64_t a)

return htonl((uint32_t)(a>>32)) | (((uint64_t)htonl((uint32_t)a))<<32);


Should the test case using the above be changed to use tor_htonll? If so I can do this in a separate patch.

Thank you in advance for your time in reading this comment.

  • Milestone changed from Tor: 0.2.??? to Tor: 0.3.0.x-final
  • Reviewer set to dgoulet
  • Status changed from new to needs_revision

Yes actually! That test file should definitely use tor_htonll(). Feel free to fix that in a separate commit.

About, your patch, looks good! I would simply test the edge cases that is the UINT64 max and 0. Also, I would define the expected "little endian" and "big endian" value as const variables instead of just "n" and then copy 4 times the expected value of converted n. It will just make things clearer and avoid us to typo anything.

Moving it to 030 milestone. Also, next time, set the patch to needs_review, will be easier for us to spot that it actually needs review :). Big thanks for this!

Thank you - I've updated the branch re the feedback. I'll open another bug (with a patch) for test_util_format.c.

Thanks again!

Oh it's fine that you do the cleanup with this branch! :) I'll look at it asap.
