According to lex(1) (the manual page for flex, which is what we use for lex):
Finally, note that you cannot put back EOF to attempt to mark the
input stream with an end-of-file.
Fixes PR bin/8707, which had been reclassified as a toolchain bug.
and sent in by Greg Hudson as seen in PR misc/3227. Basically what it
does is adds a flushall option which deletes all but localhost routes.
This is done by andoring in a flag called doall (1 means do all routes
including gateway, 0 means do a regular flush). I have seen some
platforms that do this. I tested it out on ipv4 only, it works as
advertised. Commit was approved by christos@.
pthread_attr_t objects, although most of the properties being set don't really
affect threads yet:
pthread_attr_{get,set}guardsize()
pthread_attr_{get,set}inheritsched()
pthread_attr_{get,set}scope()
pthread_attr_{get,set}stack()
pthread_attr_setstack{size,addr}()
Remove some useless assertions and error checks in the existing pthread_attr()
routines.
Implement pthread_attr_get_np(), to examine the attributes of an existing
thread. Idea and interface from FreeBSD.
Change PTHREAD_ERRORMODE environment variable to PTHREAD_DIAGASSERT, and
make it behave like libc's LIBC_DIAGASSERT. The way to disable error-checking
and aborting is now "PTHREAD_DIAGASSERT=AEL", rather than
"PTHREAD_ERRORMODE=ignore".
including (interface borrowed from FreeBSD) pthread_attr_get_np().
Remove a few limit-indicating symbols that don't actually need to be defined
(and if they did need to be defined, it would be in limits.h, not here).
takes an additional argument indicating whether this is an internal caller
taking the lock or an external (application) caller. When making an internal
lock, save the current thread cancellation state and disable cancellation
until the matching unlock. This should prevent canccelled threads from exiting
inside of stdio while holding a file lock and potentially leaving other
parts of the FILE structure in an inconsistent state.
different for locore.S and the rest of the kernel, if you redefine
it from the default value, you must also define KERNBASE_LOCORE -- this
is ugly, but so is having the same constant with two different types
depending where in the kernel it's used...
