| 4 | Subject: M-x search-backward-in-time broken... | |
| 5 | X-Windows: you'll envy the dead. | |
| 6 | ||
| 7 | In GNU Emacs 51.70.4 (i9986-unknown-linux-gnu, X toolkit) of Sat Feb 20 2199 on floss | |
| 8 | configured using `configure --with-x-toolkit=yes' | |
| 9 | ||
| 10 | The `search-backward-in-time' function appears to be broken in | |
| 177c0ea7 | 11 | Emacs 51.70. |

| 13 | Unfortunately, I can never seem to start the debugger early | |
| 14 | enough to catch the error as it happens. However I have traced the | |
| 15 | problem through source by eye, and it looks like `time-forward' can't | |
| 16 | handle negative arguments anymore. This is consistent with other | |
| 17 | symptoms: for example, `undo' (which since 51.25 has worked by passing | |
| 18 | a negative arg to `time-forward') is also broken. However, `do' still | |
| 19 | works -- it seems that `time-forward' continues to handle positive | |
| 20 | arguments just fine. | |
| 21 | ||
| 22 | No one here-and-now can figure out how to fix the problem, | |
| 23 | because the code for `time-forward' is so hairy. We're using M-x | |
| 24 | report-future-emacs-bug to request that you folks include more | |
| 25 | comments when you write it (sometime in 2198 as I recall). | |

| 27 | Thanks! | |

| 32 | P.S. You'll be pleased to know that since (time-forward N) still works | |
| c4444d16 | 33 | for N >= 0, we've used it to pre-emptively update configure.ac. |

34 | Emacs now configures and builds on every platform that will ever |
| 35 | be made. It wasn't easy, but at least that's one problem out of | |
| 36 | the way for good. If you'd like the patch, just ask. | |
