The "at most" branch was never taken since all call sites in var.c only
ever need a substring, and the target buffer is not limited. Therefore
rename the function and make it simpler.
It's ok that bmake_strldup is defined as estrndup in case of USE_EMALLOC
since that function's implementation is compatible to the "copy
exactly", it just contains some extra null checks that will never match
since the variable values cannot (well, or should not) contain null
bytes. Theoretically they can, but the behavior then depends on the
exact implementation and is unreliable, therefore nobody does this.
After all, Makefiles are used for text processing, not for binary data.
but will overflow much slower than the main pmap history.
move various debug info into kernhist. make pte array checker
into an array and use it in pmap_segtab_release() and
pmap_pte_reserve(). move check before MD callback(), incase it
wants to change ptes for some reason (they're passed in, but
this callback is currently always NULL.)
clean up some history logs to reduce the number of lines required.
functions being defined (they can still be included if quoted).
If we parsed the way POSIX specifies (leaving the exact input text of
$ and ` expansions unaltered, until required to be expanded) this would
not be needed, as the name of a function being defined does not underbo
parameter, command, or arith expansions, so xxx$3() { : ; } would just
work. But for many reasons we don't do that (and are unlikely to ever,
though maintaing both forms might be an option someday) - which led to
very obscure behaviour (if sh were compiled in DEBUG mode, even an abort())
and certainly nothing useful. So just prohibit these uses for now.
(A portable function name must be a "name" so this makes no difference
at all to posix compat applications/scripts).
A doc update is pending (the updated sh.1 also contains updates in other
areas not yet appropriate to commit).
Fixes "cgfour(4) is mis-probed as bwtwo(4)" problem on 3/80
that has been broken since NetBSD 1.6.
Now Xorg 1.20 based Xsun 8bpp color server is confirmed working
on the cgfour(4).
Should be pulled up to netbsd-9.
XXX: all MD PMAP_NC flags should be replaced with MI PMAP_NOCACHE flag.
This breaks the assumption that un_uppervp->v_mount is the upper mount.
Fix by storing the directory as un_lowervp and adapt union_readdir().
Should fix PR kern/55552: panic with union mount
