- Subject: M-x search-backward-in-time broken...
- X-Windows: you'll envy the dead.
- In GNU Emacs 51.70.4 (i9986-unknown-linux-gnu, X toolkit) of Sat Feb 20 2199 on floss
- configured using `configure --with-x-toolkit=yes'
- The `search-backward-in-time' function appears to be broken in
- Emacs 51.70.
- Unfortunately, I can never seem to start the debugger early
- enough to catch the error as it happens. However I have traced the
- problem through source by eye, and it looks like `time-forward' can't
- handle negative arguments anymore. This is consistent with other
- symptoms: for example, `undo' (which since 51.25 has worked by passing
- a negative arg to `time-forward') is also broken. However, `do' still
- works -- it seems that `time-forward' continues to handle positive
- arguments just fine.
- No one here-and-now can figure out how to fix the problem,
- because the code for `time-forward' is so hairy. We're using M-x
- report-future-emacs-bug to request that you folks include more
- comments when you write it (sometime in 2198 as I recall).
- Thanks!
- -Karl Fogel <kfogel@red-bean.com>
- P.S. You'll be pleased to know that since (time-forward N) still works
- for N >= 0, we've used it to pre-emptively update configure.in.
- Emacs now configures and builds on every platform that will ever
- be made. It wasn't easy, but at least that's one problem out of
- the way for good. If you'd like the patch, just ask.
