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);

the nt blob ends with 4 zero bytes, this is not the same as
the EOL av-pair terminator!
this makes ntlmv2 work with windows xp with LmCompatibityLevel = 3
extending factotums and the auth servers mschap implementation
to handle variable length NT response for NTLMv2.
fix some minor bugs.
only tested with cifs so far.
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.
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.
we do not need to wait for fork/execed program to finish when
not collecting waitmsg. this reduces the number of rio
processes hanging arround for each window shell just waiting
for it to terminate and then dumping the waitmsg.
U9fs(4) misuses Fcall.afid in its p9any authentication module.
The afid field of Fcall structure is only valid with Tauth or Tattach.
Tread, Twrite, Tclunk should use rx->fid instead. It's been lucky so
far to get the job done because rx->afid survives from previous
Tauth/Tattach. The issue pops up when several authentications happen
concurrently.
Test case:
u9fs = 'host with u9fs on tcp!*!564'
9fs $u9fs; for(i in 1 2 3 4 5 6 7 8){ 9fs $u9fs & }; wait
Should:
no errors
Should not:
mount failed: authentication failed
we might get a unreachable nameserver ip from a parent
nameserver. if the remaining set of nameservers does not
loop, we should try to resolve them.
so skip the loopcheck for nameservers already tried.
validurl() is just used to check if the string is a full
absolute url with a protocol scheme. we do not have to
match the host part *exactly*, only if there is *something*
in the hostpart.
Add pages for esc1+shift and esc1+ctrl - some UK USB keyboards (Dell) and it seems some
German ones: https://groups.google.com/forum/#!topic/comp.os.plan9/ycok6NTCWCg seem to
generate an esc1 + code scancode combination for the pipe/backslash key. Seems like
overkill to add two whole pages for just two keys, but there again RAM is cheap these days.
Probably should take the changes across to omap/kbd.c (and by extension bcm/kbd.c)
but the changes are trivial.
catch the error() that can be thrown by sleep() and tsleep()
in kprocs.
add missing pexit() calls.
always set the freemem argument to pexit() from kproc otherwise
the process gets added to the broken list.

from 9atom/acmearrowfun patch:
reported by mark van atten
In Plan 9 acme, if you type
{}
then go back and type text between the brackets
{Curiouser and curiouser!}
the right arrow is blocked when you want to go over the closing
bracket to continue typing to its right. (If you first go to the left,
and then back to the right, it works.)
Same for the other brackets: [ ], ( ), < >.
noted that brackets are not necessary. same behavior with any
character.
fix is to textcommit before moving.
we have to fail the whole query that got no cached
nameservers and nameservers are looping, not just omit
the looping nameserver. issuequery() will refresh
nameserver info for the domain when recursing up.
never try to resolve a nameserver address when that nameserver
is in the set of nameservers already being queried.
this situation can happen when the Ta and Taaaa RR's expire, but
the Tns records are still in the cache so there is no usable
nameserver but they still refer to each another.
stop absolute/relative dual use of RR.ttl. now RR.ttl is
*always* the *relative* ttl value. we derive absolute
timeout in RR.expire.
remove unused lookuptime field in DN. replace refs and
keep with mark field in DN. we do not care about the
number of references. only *iff* it is referenced, so
use a single bit for that (bit 0). for keep, we use
bit 1.
remove dolock parameter in dnagenever(), it is not
needed. we always need to lock.
mark local dns servers and domains as never to be aged.
the keeper bit is *just* a cache optimization, preventing
the domain and the domains it points to from being flushed.
it should not be used as a write protect bit in rrattach()
for preventing spoofing as it will prevent updates of say,
cname domains.
remove "removing spam ..." message. these are usualy just
hints, so normal. still, remove the hint as we currently
do no check if the nameserver has authority over the
cname domain.
remove "mydnsquery: trying to send to myself (%s); bzzzt"
message. this can happen when myaddr() fails for other
reasons. myaddr() will print error for us anyway.
ndb keys are strictly case sensitive, so consitently
use strcmp() when comparing attribute keys.
dblookup() used to lower case convert its name argument
inplace to match domain/sys name in ndb. better to do
the convesion in its own buffer and only read from the
name argument.
always use cistrcmp() when comparing DN.name.
the Domlen constant denotes the size of the buffer including
the null terminator. consistently use it as such.
have to hold dnlock in freearea() before reading list
head pointer.
