42074003ca kernel: dont call pprint() while holding up->debug qlock
pprint() might block or even (maliciously) call into
devproc write which will corrupt the qlock chain on attempt

8cef1794d6 mothra: add regular expression text search (thanks mischief, sl)
this works differently from mischiefs original patch. instead of
overloading the address bar, we popup our own enter box. the
function can be invoked from the menu or by hitting ^F.

48d2f14f80 page: implement bookmarks (thanks trav_ for starting it)
add new functions pageaddr() that returns a string describing
the page to be loaded. it is in the form of:

/path/to/file!pagename!subpage!....

one can jump to such a page by calling trywalk(name, addr)
where name and addr get concatinated with ! to form a page
address and then the currently loaded pages are walked up
to the nearest page which is then returned. (or nil when
not found). the remaining address will be set in the global
pagewalk variable.

once pages get loaded (asynchronously), pagewalk1() gets
called again on addpage() and continues the walking up to the
last page.

new program flag -j <addr> was added to jump to a page on
startup.

page address (without filename) can also be supplied in
plumb message with the "addr" attribute.

56300f72e8 rio: dont consider shell characters as part of the filename for auto completion
rio looks backwards in the line for the beginning of a filename
that needs to be completed with ^F. this change makes the
characters: =, ^, ( and { stoppers, so filename completion
will work in all these cases:

foobar=/foo/ba^F; for(i in (fo^F ba^F)){/bin/baz^F

this means completion will not work for prefixes having these
special characters in them.

thanks to burnzez for bringing it up.

ea6fea596b devether: remove qfull prints and fix loopback packet handling of etheroq()
dont spam the console with qfull warnings. this makes things worse.

handle loopback packets as stated in the comment. we call etheriq()
with fromwire=1 for loopback packets so etheriq() can pass the packet
on (without copying) or free it. dont inhibit interrupts while calling
etheriq(). etheriq() can safely be called from process and interrupt
context. it is unclear what this was supposed to fix and testing didnt
seem to have any odd effects.

6946118644 devssl: use parsecmd() to process control message to get rid of 128 byte stack buffer limit
(11:02:29 PM) me: why is buf in /sys/src/9/port/devssl.c:/^sslwrite only 128 bytes?
 (11:02:58 PM) me: it makes it so you can't use a 128 bytes secret as negotiated by infauth in a secretin or secretout ctl message
 (11:03:30 PM) me: which in turn means you can't use such a secret with pushssl(2)
 (11:06:15 PM) me: inferno's sslwrite is limited to 32 bytes, but its ssl library writes to the secret files instead of to the ctl file
 (11:08:50 PM) mischief: what should it be instead of 128 bytes
 (11:08:58 PM) me: larger
 (11:09:16 PM) mischief: how about 129 bytes?
 (11:09:59 PM) me: also broken in 9front, by the way
 (11:15:14 PM) me: i guess it should be replaced with parsecmd

71dbddef16 draw: fix drawing of replicated source image on memlayer with a clip rectangle
when a replicated source image with a clipr with clipr.min > Pt(0, 0),
drawclip() would properly translate the src->clipr on the dstr
but then clamp the source rectangle back on src->r.

while traversing down multiple layers, this would cause the translation to
be applied multiple times to the dst rectangle giving the wrong image result.

this change adds a new drawclipnorepl() function that avoids the clamping
of source and mask rectangles to src->r and mask->r. this is then used in
libmemlayer.

the final memimagedraw() call will call drawclip() which will do the final
claming.

a testcase is provided:

#include <u.h>
#include <libc.h>
#include <draw.h>

Image *blue;
Image *red;

void
main(int, char *argv[])
{
	Image *i;

	if(initdraw(nil, nil, argv[0]) < 0)
		sysfatal("initdraw: %r");
	i = allocimage(display, screen->r, screen->chan, 1, DWhite);

	red = allocimage(display, Rect(0,0,1,1), screen->chan, 1, DRed);
	blue = allocimage(display, Rect(0,0,1,1), screen->chan, 1, DPaleblue);
	replclipr(red, 1, Rect(10, 10, 110, 110));
	replclipr(blue, 1, Rect(11, 11, 111, 111));

	/* draw on non-layer, works correctly */
	draw(i, i->r, red, nil, ZP);
	draw(i, i->r, blue, nil, ZP);
	draw(screen, screen->r, i, nil, i->r.min);
	flushimage(display, 1);

	/* draw on (screen) layer is too far to the right */
	draw(screen, screen->r, red, nil, ZP);
	draw(screen, screen->r, blue, nil, ZP);
	flushimage(display, 1);

	for(;;){
		sleep(1000);
	}

d7f90a9096 kernel: simplify pexit(), avoid making wait record for RFNOWAIT (parentless) procs
replaced the p->pid != 0 check with up->parentpid != 0 so
p->pid == up->parentpid is never true for p->pid == 0.

avoid allocating the wait records when up->parentpid == 0.

4fd55abb8e kernel: fix pexit() Waitmsg memory leak.
when a process got forked with RFNOWAIT, its p->parent will still
point to the parent process, but its p->parentpid == 0.

this causes the "parent still alive" check in pexit to get confused
as it only checked p->pid == up->parentpid. this condition is *TRUE*
in the case of RFNOWAIT when the parent process is actually dead
(p->pid == 0) so we attached the wait structure to the dead parent
leaking the memory.
