| <h3>Comments about the issues</h3> |
| <ul> |
| <li>2183 - We're missing tests for match_results (copy ctor, move ctor). I committed them in r344988.</li> |
| <li>2184 - We're missing tests for match_results (copy assign, move assing). I wrote them. Unfortunately, the move-assign test fails.</li> |
| <li>2412 - </li> |
| <li>2682 - Eric? </li> |
| <li>2697 - </li> |
| <li>2936 - </li> |
| <li>2943 - Eric? I suspect that this is no change for us.</li> |
| <li>2960 - </li> |
| <li>2995 - We used to do this. Reverting r320604 and r321124 will get us back there.</li> |
| <li>2996 - </li> |
| <li>3008 - </li> |
| <li>3025 - </li> |
| <li>3031 - Marshall says: I don't think we have to do anything for this issue. Maybe some tests; maybe a static_assert.</li> |
| <li>3037 - Marshall says: We don't have std::polymorphic_allocator yet.</li> |
| <li>3038 - Marshall says: We don't have std::polymorphic_allocator yet.</li> |
| <li>3054 - Marshall says: We already do this; may need to update some tests.</li> |
| <li>3065 - </li> |
| <li>3096 - Eric? </li> |
| <li>3116 - </li> |
| <li>3122 - Marshall says I have updated the comments in <version> and in the tests.</li> |
| <li>3127 - Marshall says: We don't have basic_osyncstream yet.</li> |
| <li>3128 - </li> |
| <li>3129 - Marshall says: This is an easy change; I think this is more wording cleanup than anything. I will prepare a patch</li> |
| <li>3130 - </li> |
| <li>3131 - Only changes 11 & 12 affect libc++. </li> |
| <li>3132 - Marshall says: I don't think we have to do anything for this issue</li> |
| <li>3134 - Marshall says: I don't think we have to do anything for this issue</li> |
| <li>3137 - Marshall says I have updated the comments in <version> and in the tests.</li> |
| <li>3145 - Eric? </li> |
