we dont have to
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.

This patch corrects a minor problem with telnet when using
the notkbd option (-n).

patch/u9fs-afid)
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.
|
|
the wire
we'd like to keep Url.host in unicode for factotum key
lookup. only when we send the url in a request, we have
to convert it to ascii.

drawterm is much better maintained by russ cox,
so removing this outdated copy.
for a more recent version, go to:

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.

only cache what we asked for or need to resolve the
query. filter out everything else.
|
|
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.

inplace lower case conversion, cleanups
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.

quanstros 9atom)
for read capacity (10 (0x25) if we have more than
4 billion sectors, we must not return nsectors % (1<<32),
we must return 0xffffffff.

the image cache should not hold onto the text file channel
when not neccesary. now, the image keeps track of the number
of page cache references in Image.pgref. if the number of
page cache references and Image.ref are equal, this means
all the references to this image are from the page cache.
so no segments are using this image. in that case, we can
close the channel, but keep the Image in the hash table.
when attachimage() finds our image, it will check if Image.c
is nil and reattach the channel to the image before it is
used.
the Image.nocache flag isnt needed anymore.

the libmad samples need to be scaled properly. the
previous assumption was that it is 32 bits, but it
really is MAD_F_FRACTBITS + sign bit and rest used
for overflow.
thanks eekee!
