ad ab62b04dc5 Allow atomic ops to be built as part of libpthread. 2008-09-29 08:43:00 +00:00
haad 185aec71fe Add prop_array_add_int* and prop_array_add_uint* functions. These functions 
can be used to append specified type to the end of prop_array_t.

Ok'ed by @joerg.

Patch from joerg@
 2008-08-20 19:58:33 +00:00
joerg 245e086321 Unify the implementation of strto{l,ul,ll,ull,imax,umax,q,uq} into one 
version for signed and one version for unsigned data types.

Add a check for supported bases and set errno (userland) or panic
(kernel, libsa) otherwise.

Make strto{ll,ull,imax,umax} normal symbols and just keep the underscore
versions as strong alias.

Obtained from DragonFly, based on the wide char version from Citrus.

christos ecd6bc7086 typo in comment and white-space fixes mostly from Stathis Kamperis 2008-08-11 05:54:21 +00:00
thorpej 4ce0dc3a15 Fix an issue introduced with the prop_stack change: It's not a good idea to 
return a 3-value enum from a function declared to return bool.  This broke
the recurse case for prop_object_equals().  Instead, declare the object type
equals routine to return a _prop_object_equals_rv_t.

Give the same treatment to the object type free routines: declare them to
return a _prop_object_free_rv_t, and consistently check those return values
againt the enum type.

Tidy up some whitespace while we're here.

dholland 154fe9b1d9 Don't convert cpuid_t through int while testing it for being in range. 
(Might truncate it, for one thing. Also, if the shift result is < 0 the
demons have already flown out of our nose.)

Fixes some -Wsign-compare warnings.

he d6e5879de3 Be consistent in how cpuset_nentries is computed in the kernel and 
in user-land.  This fixes the user-land part.  Now "cpuctl identify 0"
gives a result instead of getting EINVAL from the set-affinity syscall.

The prop_array_util family of functions are provided to make getting and

tron 2916b940f8 Replace _prop_rwlock_tryrdlock() by a macro _PROP_RWLOCK_TRYRDLOCK(). 
This avoids build failures in stand alone binaries (e.g. bootloaders)

simonb 4ec02db9e9 Fix a "#define<tab><tab>" that crept in to previous. 2008-05-07 05:40:01 +00:00
xtraeme 35fe7cdcf1 prop_object_iterator_next() and prop_object_iterator_reset() were 
acquiring the rwlock recursively in some paths.

Introduce _prop_rwlock_tryrdlock() and use it in these functions, so
that the rwlock is *always* acquired once, while here add some
_PROP_RWLOCK_OWNED asserts to verify.

This definitely fixes the "locking against myself" panics.

xtraeme 771a05b730 Do not acquire the rwlock recursively in prop_{array,dictionary}_iterator_reset() 
when prop_{array,dictionary}_copyout_ioctl() is called.

Introduce _PROP_RWLOCK_OWNED() which is a KASSERT(rw_lock_held(lock))
and use it in those two functions, also acquire the rwlock in other
places where it is required now.

This fixes a LOCKDEBUG panic "locking against myself", as reported by
Geoff C. Wing in current-users@.
