CVS Tags: HEAD
Changes since 1.59: +2 -170 lines
Diff to previous 1.59 (colored)

Delete support for the LESSOPEN and LESSCLOSE environment variables
aka the "Input Preprocessor": it's been a source for multiple
security bugs in the past as everything has to deal with handling
arbitrary filenames and generally resulted in multiple TOCTOU issues.
The base system never included a default LESSOPEN setting like some
Linux distributions did, but it's a suds-filled sink full of knives
to try to use safely.

Remove wpath from secure mode pledge.

Upstream removed history file support for secure mode. The history file
feature is off by default already, disallowing it altogether in secure
mode allows us to drop wpath.

Added a note about it to manual page.

Delete what remains of the support for combining characters into
ligatures: it was incomplete (only for the Arabic script and only
for the single ligature LAM WITH ALEF) and it was implemented in a
way that is unsustainable (with a static table inside less).

If we ever want ligature support, we are better off making a fresh
start.  However, for languages like Arabic and Persian, even that
wouldn't really be useful without having bidirectional support first.
