add glob information to the word structure so we wont accidently
deglob quoted strings containing the GLOB. we store Globsize(word)
in in word->glob which avoids recalculating that values and the
check if a word should be globbed quick.
globlist() now substitutes the word inplace avoiding the copying
when all words are literals and avoids recursion.
minor cleanups: use list2str() in execeval(), move octal() to
unix.c, remove the (char*) casts to efree().
when using rio auto-complete to resolve file names for the "attach:" and
"include:" headers, the auto-completer might leave whitespaces at
the end of the line which leads upas/marshal to not find the file.
it is now possible to configure additional interfaces (like wifi)
and store the network information while preserving old entries
in /net/ndb. this allows to easily switch from ethernet to wifi
and have dhcp configure dns without having to clear /net/ndb.
netmkaddr() can return a the pointer to the host string if
it is already a full dial string. but we assumed to get
a copy and freed it before returning.
when _syserrno() fails to map a plan9 error string to
a unix error number, we copy the plan9 error string
to the per process error buffer "plan9err" and set
errno = EPLAN9.
when strerror() is called with EPLAN9, it returns
a pointer to the plan9err buffer.
I introduced a regression in sed that currently has screwed up
/sys/lib/man/secindex.
The issue is that sed 's/$/ foo/g' will actually replace the newline
character with foo instead of just appending at the end of the line.
This only makes a difference when sed is operating on a multiple line
record. The effect is a record like:
foo
bar
baz
becomes:
foo foobar foo baz foo
instead of
foo foo
bar foo
baz foo
problem is NaN() produces a SNaN, not a QNaN... and on the 387,
storing 80 bit SNaN in register to a 64-bit memory destination
traps.
SNaN/QNaN encoding is machine specific. mips has the qiet/signaling
bit inverted.
disabling fp exception in main() now, but that sucks.
i think the best solution would be to not even call strtod() in
is_number() but just write a regex or a little state machine that
will only accept numbers without nan and ±inf.
that might even make it faster and is more robust than relying on
the os's strtod() details.
