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
|
2003-02-04 14:56:31 +00:00
|
|
|
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!

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.
