Subject: bug#56683: 29.0.50; long lines fix doesn't work correctly when lines are truncated
Date: Mon, 25 Jul 2022 22:22:22 +0000 [thread overview]
Message-ID: <8a3eaeef01b9a103450a@heytings.org> (raw)
In-Reply-To: <83r12djjvm.fsf@gnu.org>
By the way, we should also decide what to do when the user enables
truncate-lines in a buffer with "really too long" lines. With
DISP_INFINITY == 10000000 (its current value), and with a character pixel
width of 20 (a not uncommon value nowadays with HiDPI screens), lines
longer than 500000 (single-width) characters will not be displayed
correctly. With a larger character pixel width, or with characters
occupying more than one column, that would be even less.
Given:
1. that there has not been a single bug report about the fact that
truncate-line does not work correctly with "really too long" lines in the
last 20 years,
2. that the limit above, caused by DISP_INFINITY, is not much more than
10000, the default value for long-line-threshold, and
3. the remaining slowdowns caused by truncate-lines,
I'd be in favor of simply disabling truncate-lines when
long_line_optimizations_p is set.
