In the sched() function, the call to reprioritize()
must be done before we set up, as reprioritize()
calls updatecpu(), which determines if the process
was running or not based on p == up. So move
the call to runproc() itself.
while rehashing the same files over and over will work
just fine, it can be slow with a large number of large
files; this makes 'git/comit .' perform much better in
repos with a large number of large binary blobs.
compress when the log doubles in size, rather than
using a fixed size heuristic; this means that we
don't start compressing frequently as the log gets
big and the file system gets fragmented.
this happens in libframe:
/sys/src/libframe/frutil.c:80: x -= (x-f->r.min.x)%f->maxtab;
but there's no way to control when the user changes the
maxtab value, so it's samterm's responsibility to
sanitize it.
we were copying the owner and group of the parent dir into the fid
on create, but we forgot the mode; fix that, so that we don't check
perms against the wrong dir.
The Italian keyboard layout is ISO, and unlike the ANSI layout,
it has an extra key between Shift and Z, and the key above Enter,
which becomes vertical, is moved to the bottom left of it.
- the key between Shift and Z is mapped to `<`, and shift+`<` is mapped to `>`
- the old `>` (at the bottom left of Enter) is mapped to `ù`
- shift+`ù` is mapped to `§`
- the old shift+`"` is mapped to `°`
- altgr+`'` is mapped to backtick
- altgr+`ì` is mapped to `~`
- altgr+`e` is mapped to `€`
- shiftaltgr+`[` is mapped to `{`
- shiftaltgr+`]` is mapped to `}`
This seems to have been around but not compiled since the third edition.
Remove it and the accompanying SMBus machinery that is only used
for this driver.
When modifying a sparse file, it's possible to get
clobbers and clears to item s that don't exist; in
this case, we try to apply to an empty kvp, and
assert -- we should just not apply.

{
uchar a[3];
float f = a[2] | a[1] | (a[0]/1.2);

the code above used to generate impossible
code in the linker like:
main: doasm: notfound from=34 to=35 (872) ORL X0,X1
main: doasm: notfound from=34 to=35 (872) ORL X0,X1
main: doasm: notfound from=34 to=35 (872) ORL X0,X1
with the change, the compiler correctly rejects it:
incompatible types: "UINT" and "DOUBLE" for op "OR"
i assume the BNUMBER in the type matrix must have been
a oversight.
do not add default route when address is
deprecated (preflt == 0).
delete previous default route on router change.
implement rfc4862 section 5.5.3 processing rules
in regard to remaining valid lifetime.
In addition to removing expired default routes,
ask devip to clean out expired addresses as well.
In the future, devip might do something more
sophisticated than just checking the valid life time
like also considering if the address is still begin
used by active connections.
we shouldn't need to defer reclamation for procs that
don't actually interact with the tree directly, especially
since if they send on a channel they can stall for a while.
This change covers three improvements:
- inline the limbo entry into the objects
being freed, meaning we don't need to
allocate, and thus can't fail to free
an object when we're out of memory
- Preallocate Bfree objects, for the same
reason above.
the build process could be cleaned up a lot more. the default.*.h headers are
basically only used in cross-compilation, but every usable arch has its default
header already, so all the mkfile effectively does is copy it to $objtype.h. it
would perhaps make more sense to just run mk on any new arch and copy to a new
default.$objtype.h and get rid of a lot of this stuff. but then it's not really
worth messing with this further, so leaving it as is.
We were inserting very oversized deletion messages when
removing a file, instead of inserting the right size
message. This also batches the insertions, reducing the
number of upserts.
37e65b331b
Was to adjust the compiler to better match the ISA w.r.t.
subtraction, but was overzelous and rewrote all additions instead of
just those with constants.
5390130426
Intended to restrict compiler generated immediate operations to only
those of which can be encodable by the ISA. However the check for
signed constants was incorrect and resulted in constants that do not
properly encode.
0c6fd079ce
Attempted to classify address literals to save on instruction
encoding, but this is actually not possible. We have to walk the
program first to derive some of the constants (INITDAT depends on
etext) so we can not classify them here. Instead we should just limit
address literals to 32 bits (with sign extension) as a worst case. It
would be possible in the future to do a pass over to program later and
find address literals that only need one instruction instead of two
but this works for now.
