the shared command language assumed 512 byte sectors, which is
not the case for fdisk as it uses cylinders for the block unit.
so we introduce an extra argument in the Edit structure and
parseexpr() function so byte sizes are properly converted to
the block unit when the K,M,G and T postfixes are used.
the pcap files produced by snoopy had the wrong timestamps because it expected:
/* magic=0xa1b2c3d4 */
ulong ts_sec; /* seconds*/
ulong ts_usec; /* microseconds */
but we wrote:
uvlong ts; /* nanoseconds */
now, we write:
/* magic=0xa1b23c4d */
ulong ts_sec; /* seconds */
ulong ts_nsec; /* nanoseconds */
as the generated parser intermixes lines from .y source
and the parser text, the line source/lineno for yyparse()
shows up wrong in the debugger. to make stack traces a
bit less crazy, put a #line 1 "/sys/lib/yaccpar" before
copying in the parser text.
when the "resize" wctl was used on a hidden window, the window
was put back on the screen, however, it was not removed from
the hidden[] array so trying to hide the window again failed
because whide() assumed it was already hidden.
the fix is to not unhide the window, but preserve the hidden
state, so windows can programmatically be reshaped and moved,
but will remain hidden unless explicitely unhidden.
to solve the usb device enumeration race on boot, usbd creates /env/usbbusy
on startup and once all devices have been enumerated and readers have consumed
all the events, we remove the file so nusbrc/bootrc can continue. this makes
sure all the usb devices that where plugged in on boot are made available.
code assumed the accessdir() call would always mark the block dirty, but
this is not the case when noatime flag is enabled. this was reported by
michael in bug:
"open/with_noatime_option_cwfs_doesnt_preserve_changes_in_file_permissionowner"

from charles forsuth:
because the previous version thought OINDEX might have a side effect, it
stopped it building a tower of them.
probably the best thing is to limit that anyway, since each one consumes
2-3 registers, so towering them can
keep even more active, and the x86 hasn't got that many.
the quick hack is to return that case to the earlier state by treating
OINDEX as a side-effect in side().
it's not a bad thing to do in the OSTRUCT case, for similar reasons: it's
better to collapse the indexed pointer
into a direct register, instead of repeating the indexing operation through
the copying of the value.
OINDEX isn't a machine-independent operation, so it doesn't affect the uses
in ../cc
- cover more cases that have no side effects
- ensure function has complex FNX
- pull operators out of OFUNC level
- rewrite OSTRUCT lhs to avoid all side-effects, use regalloc() instead of regret()
maximum file size is 4GB-1 as the file length is stored in
a 32 bit long. make sure it doesnt overflow on write or
or truncate. interpret the file length as unsigned. pass
vlong to readfile()/writefile()/truncfile() so we can
handle overflows and not just ignore the upper bits.
