the main effect of this is to make GCC and other libiberty using
tools use /tmp instead of /var/tmp for compiler temp files,
which can be a bottleneck on larger systems.
a survey of other platforms shows only OSX also uses /var/tmp,
everyone else has switched to /tmp long ago.
cons: some smaller systems may have a smaller /tmp than /var/tmp,
and this may cause builds to fail with out of space earlier.
point the build to /var/tmp using TMPDIR in this case.
one can argue that setting TMPDIR would work around this, but we
want to have the effect for all users without having special setup.
state of the stream. Change argument of the seek function to funopen() from
fpos_t to off_t. Make f{g,s}etpos() use the new fpos_t struct, while providing
backwards compatible entry points. Approved by releng@
sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.
builtin attributes for (for symmetry and consistency). In the future this
might change to use compiler-neutral macros. On the other hand I don't
know of any other compiler that provides other macros with similar
functionality, so why bother?
EMFILE. We treat _file as an unsigned short to double our range, with a
special case for -1 (closed). Make a note of what we should do about stdio
if we ever bump libc. We could change _file in the future compatibly to an
int by putting it in the extension space but for now we don't bother.
include path: the normal header files now include the "SSP" ones (which one
should note are not really named right: SSP and FORTIFY_SOURCE are independent
features).
Disable USE_SSP on targets where the compiler doesn't support it at all
(mips, alpha) or it's known broken (sh3). But enable FORTIFY_SOURCE,
without SSP, on those platforms -- tested on mipsel.
- add __SAFE flag, to indicate that we want async-signal-safe functionality
only.
- add snprintf_ss, and vsnprintf_ss; these are undocumented on purpose.
file is POSIX visible and the usage isn't #ifdef _KERNEL)
Discussed with core. I may need to go farther than this but for now
compilations done with gcc -ansi (i.e. firefox) will be okay.
* Make vfprintf_unlocked() an internal function, c.f. __svfscanf_unlocked().
* Add internal names for arc4random(), endnetpath(), fhstatvfs(),
fstatvfs(), mkstemp(), shquote(), statvfs(), taddr2uaddr(), uaddr2taddr(),
uuid_create_nil(), uuid_is_nil(), and wcwidth().
* Include namespace.h where supposed to.
by the application, all NetBSD interfaces are made visible, even
if some other feature-test macro (like _POSIX_C_SOURCE) is defined.
<sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE,
_POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve
existing behaviour.
This has two major advantages:
+ Programs that require non-POSIX facilities but define _POSIX_C_SOURCE
can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS.
+ It makes most of the #ifs simpler, in that they're all now ORs of the
various macros, rather than having checks for (!defined(_ANSI_SOURCE) ||
!defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place.
I've tried not to change the semantics of the headers in any case where
_NETBSD_SOURCE wasn't defined, but there were some places where the
current semantics were clearly mad, and retaining them was harder than
correcting them. In particular, I've mostly normalised things so that
_ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE,
_XOPEN_SOURCE and _NETBSD_SOURCE in that order.
Tested by building for vax, encouraged by thorpej, and uncontested in
tech-userlevel for a week.
