address space that is fully locked and marked B_KERNEL_AREA. It can
thus be accessed by the kernel without additional checks.
* For each userland thread we do create a user_thread structure in that
area. The structure is accessible from userland via TLS, using the
private get_user_thread() function.
* Introduced private userland functions [un]defer_signals(). They can be
used to cheaply disable/re-enable signal delivery. They use the
user_thread::defer_signals/pending_signals fields which are
checked/updated by the kernel.

* Added BDiskDeviceRoster::GetDiskSystem() method, that can get a disk system
by short/pretty/module name - since they should all be unique, I put them
in a single namespace, please complain if you don't like that :-)
* Cleaned up DiskSystem.h and DiskDeviceRoster.h according to the updated
header guidelines.
* Renamed ntfs pretty name from "ntfs File System" to "Windows NT File System".

arguments they get a single thread_creation_attributes structure now.
* Added stack_address and stack_size to thread_creation_attributes,
which allow to specify the stack size or the stack to be used for the
new user thread.

compile time checks. Incidently those are not totally uncommon in
portable code.

* Fixed operator=(): the second argument of SetTo() is a boolean (normalize),
not the length of the buffer.

simply created as files in /boot/var/shared_memory/. The Bootscript

* Changed the semantics of unnamed semaphores. Before parent and child
of a fork() would always share an earlier created semaphore. Now we do
that only, if the "shared" parameter of sem_init() was true. That's
still not quite the behavior Linux and Solaris have, but should be
perfectly fine with how reasonable code would use the API.
* There's a global table for shared unnamed semaphores now. ATM a
semaphore is leaked when no one explicitly destroys it (just as with
named sems).
* Enforce per-team and global semaphore number limits.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25362 a95241bf-73f2-0310-859d-f6bbb57e9c96
not supposed to be passed to pathconf() or sysconf().
* Added POSIX semaphore related macros.

* Allow userland teams to create areas below 1 MB when requested specifically.
* Note, this is a temporary solution - see the comments in the code.

- Implemented BMediaFile::Copyright, which just calls Copyright() of the extractor. So this is just a simple pass through.
- Style cleanup (mostly whitespaces)
Problem is that our readers currently return the copyright of the source code, not the copyright of the MediaFile itself, like the BeBook documents. Thus, we might need to change all readers to return appropiate data or behave differently for Haiku readers.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25356 a95241bf-73f2-0310-859d-f6bbb57e9c96

Realtime option group). The implementation should be complete, but is
totally untested yet.

module interface. They directly operate on iovecs and thus allow
protocols that don't need it to avoid the creation of a net_buffer.
* Adjusted the socket module to support the new hooks. If they are
present, they will be chosen over the old hooks.

module to the stack module. There's a dedicated struct
ancillary_data_container, now. One can just set the container on a
net_buffer.

* Trivial adjustments of code using mutexes. Mostly removing the
mutex_init() return value check.
* Added mutex_lock_threads_locked(), which is called with the threads
spinlock being held. The spinlock is released while waiting, of
course. This function is useful in cases where the existence of the
mutex object is ensured by holding the threads spinlock.
* Changed the two instances in the VFS code where an IO context of
another team needs to be locked to use mutex_lock_threads_locked().
Before it required a semaphore-based mutex implementation.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25283 a95241bf-73f2-0310-859d-f6bbb57e9c96
that can unlock the mutex, so one bit is sufficient.
* Added cutex_init_etc() which has an additional "flags" parameter.
The only specifyable flag is CUTEX_FLAG_CLONE_NAME, which causes the
function to strdup() the given name and free() its copy in
cutex_destroy().
* cutex_destroy() does now unblock waiting threads.

name, couldn't resist :-P). It's semantically equivalent to a mutex,
but doesn't need a semaphore (it uses thread blocking and a simple
queue instead). Initialization can't fail. In fact it is ready to use
without initialization when living in the bss segment, also in the
early boot process. It's as fast as a benaphore in cases of low lock
contention, and faster otherwise. Only disadvantage is the higher
immediate memory footprint of 16 bytes.
* Changed how the "thread" and "threads" debugger commands list the
objects they are waiting for. Cutexes are also included.

the selecting thread, which has obviously no effect.
* Changed select_info::events to vint32. It is now updated atomically.
This removes a race condition when concurrent threads would notify at
the same time.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25273 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Made the pointers const.
* Changed how the ARP module maintains its arp_entry::request_buffer: it
now uses the atomic_pointer*() functions to make sure there is no race
condition, and it's deleted only once.
* Getting an ARP entry would return uninitialized data, if the entry hadn't
been resolved yet.

64-bit safe version of atomic_test_and_set() for pointers:
atomic_pointer_test_and_set().
* The VFS is now using this function (it's not used anywhere else in the
kernel this way).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25260 a95241bf-73f2-0310-859d-f6bbb57e9c96
this (seems to be what R5 BStatusBar does):
* combine the "trailing text" with the "trailing label" and truncate the
resulting string on the left side according to the width of the entire
control
* combine the "label" with the "text" and truncate that on the right side
according to the space left by the right hand text.
-> No more overlaps (theoretically, in practise there are still overlaps
because our BFont::TruncateString() does not respect the width in some
situations.)
* Changed _SetTextData() accordingly, it is not used anymore for the
label and trailing label, and could therefor be simplified a little.
* fixed _BarFrame() to not return fractional coords, which could sometimes
leave a dirty line of pixels.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25244 a95241bf-73f2-0310-859d-f6bbb57e9c96
* cache paranoia was always enabled.
* Changed from paranoia on/off to levels. Adjusted the macros to take a
level argument.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25215 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added "mode" parameter to set_paranoia_check(), which specifies
whether the check is supposed to already exist/not exist yet. This
allows for, as it turns out, very useful additional tests. Added
{ADD,UPDATE}_PARANOIA_CHECK macros that imply the used "mode"
parameter.
* PARANOIA_SLOT_COUNT was accidentally redefined in the source file.
* Fixed remove_paranoia_check(). It didn't remove anything.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25207 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added capture_tracing_stack_trace() which allocates space in the
tracing buffer and captures the stack trace according to the given
parameters.
* Added TraceOutput::PrintStackTrace() to print a stack trace thus
created.
* Added TraceEntry::DumpStackTrace() callback which is supposed to print
a stack trace for the entry, if it can do that.
* Added "--stacktrace" switch to the "traced" command, which causes the
stack traces for all entries that have one to be printed as well.
