the caller of macexpand() needs one more byte in
the buffer to append peekc.
make macexpand() actually check for buffer overflow.
just use strdup() to duplicate include file name
instead of the hunk dance.
move GETC() macro in cc.h

the results of the time calculation were garbled -- and
apparently negative on my system when testing, so the
test passed when it shouldn't have.

not what I wanted to commit.

same as sam and vt, three clicks selects a
whitespace-delimited line.

it is probably almost always a good idea to use
double buffering with a unaccelerated framebuffer.

size detection (thanks kenji)
looks like linux changed the device tree names for
the memory node:
https://github.com/raspberrypi/linux/commit/4b17654f51fd87c42cda3217b0863e6aa1df49b9#diff-ac03c9402b807c11d42edc9e8d03dfc7
this fixes the memory size detection with latest firmware
on raspberry pi4-b (4GB) for kenji.

never looked right outside of drawterm on osx (mea culpa). this is easy to change for anyone who prefers something else, but it's difficult to imagine native users preferring our very fuzzy dejavusans to anything else.

with scroll-wheel scrolling, this case can happen with the
command window:
umbraticus → cinap: create fullscreen file buffer by right-clicking in cmd window

add a buffer size argument to macexpand() and check for
overflow.
check for overflow when parsing #include directives.

slookup() copies to symb, so use the symb[NSYMB] buffer directly
to declare type conversion functions and get rid of the arbitrary
sized local buffer. replace sprint() with snprint().

we were implicitly depending on UMINUS being the last entry
in the operator table -- that's fragile.
|
|
We used to treat all operators as right associative,
which means that we would evaluate them incorrecty.
For example, '2 - 1 + 1' would evaluate as '2 - (1 + 2)',
instead of '(2 - 1) + 1'.
This adds an assoc parameter to struct pri, and then uses
it to decide how to evaluate operators.

when pushing expressions in cpp, particularly complex ones could
overflow the stack and silently corrupt our data structures. add
checks when we push, and bump the stack size up.

for floating point operations, reuse the return register
on the right hand side if it has higher complex number
than the left hand side to conserve registers.
this makes the following code compile, that was previously
run out of floating point register:
float
f(float r[15])
{
return (r[0] + (r[1] * (r[2] + r[3] * (r[4] + r[5] * (r[6] + r[7] * (r[8] + r[9] * (r[10] + r[11] * (r[12] + r[13] * r[14]))))))));
}
the downside is that this produces extra move operations.

|
When using aux/getflags, it produces unnecessarily obscure
names for the flags. This allows the caller of aux/getflags
to support arbitrary names.

BurnZeZ reported this the other day. It seems like if we have
a pipeline that looks like:
fn foo{cat < <{echo hi}}
then the '<' will get merged in /env/'fn#foo'. This change
fixes pcmd to add a space. It looks to me like this is the
only token that can get merged this way by pcmd.

the maximum number of ip stacks is a implementation detail
of devip. it is 128 currently, instead of 16 as suggested
in the manpage.

The previous patch to plumb non-whitespace segments was
confusing due to lack of visual feedback. This removes
the empty selecton plumb behavior, and instead makes
triple clicking work to get a plumbable selection.

when running ndb configuration, we might inherit the ipgw=
attribute from the ipnet pointing to our own ip address
(we are the default gateway). ignore such entries.
do not add default routes with gateway equal to our own
local (ip4) or link-local ip address (ipv6).
|
|
Plumbing text in vt requires selecting the text that you
want to plumb precisely. This patch makes plumbing behave
the same way that it does in rio.
|
|
ndb(6) states that ipgw needs to be an ip address,
however, attempting to resolve ipgw is not difficult
and already done by ip/dhcpd.

mysbrk() was only used in gethunk() and should not be
called by anyone, so dont export the symbol.
simplify gethunk() using brk().
double allocation size on each call until we reach
1000*NHUNK.
use signed long for nhunk as alignment rountin might
make it negative and handle that case.
