string, shall not fail, if the buffer is too small, and shall return
the length of the string actually written into the buffer.
* Adjusted rootfs, devfs, and bfs accordingly. Also adjusted their
read_stat() hooks to return the correct symlink length in st_size.
* Our readlink() does now comply to the standard (and BeOS).
Additionally if the buffer is big enough it is nice to non-conforming
apps and null-terminates it.

BeOS R5's glue code incorrectly calls _thread_do_exit_notification()
when main() returns, while Haiku does that in exit(). Therefore when
terminating this way the exit hooks were called twice for executables
built under BeOS R5. This caused e.g. NetPositive or the R5 svn to
crash on exit (our network code actually uses those hooks).
Fixes bug #1742.

As (our) gcc unfortunately uses atexit() to clean up lazily initialized static
variables inside functions we have to ensure that we do the right thing with
unloadable shared objects. In case a shared object was unloaded that installed
an atexit() hook the application would crash on exit. We now implement a
callback into libroot that is used to call all the atexit() hooks of a
component that is to be unloaded. Most prominently this fixes the media_server
crash at shutdown.

23139 into trunk, with roughly the following changes (for details svn
log the branch):
* The int 99 syscall handler is now fully in assembly.
* Added a sysenter/sysexit handler and use it on Pentiums that support
it (via commpage).
* Got rid of i386_handle_trap(). A bit of functionality was moved into
the assembly handler which now uses a jump table to call C functions
handling the respective interrupt.
* Some optimizations to get user debugger support code out of the
interrupt handling path.
* Introduced a thread::flags fields which allows to skip handling of
rare events (signals, user debug enabling/disabling) on the
common interrupt handling path.
* Got rid of the explicit iframe stack. The iframes can still be
retrieved by iterating through the stack frames.
* Made the commpage an architecture independent feature. It's used for
the real time data stuff (instead of creating a separate area).
* The x86 CPU modules can now provide processor optimized versions for
common functions (currently memcpy() only). They are used in the
kernel and are provided to the userland via commpage entries.
* Introduced build system feature allowing easy use of C structure
member offsets in assembly code.
Changes after merging:
* Fixed merge conflict in src/system/kernel/arch/x86/arch_debug.cpp
(caused by refactoring and introduction of "call" debugger command).

vfs_select.h, respectively moved most of it into the new kernel
private header wait_for_objects.h.
* Added new experimental API functions wait_for_objects[_etc](). They
work pretty much like poll(), but also for semaphores, ports, and
threads.
* Removed the "ref" parameter from notify_select_events() and the
select_sync_pool functions as well as from fd_ops::fd_[de]select(). It
is no longer needed. The FS interface select() hook still has it,
though -- the VFS will always pass 0.
* de]select_fd() take a select_info* instead of a select_sync* + ref
pair, now. Added respective functions for semaphores, ports, and
threads.

this is good. I will test it more with WebKit later.

* get_signal_stack() checked the wrong sig_action field (index is signal-1), also,
it had an off-by-one error in the stack range check.
* factored out a restart_syscall() function to avoid code duplication
* arch_setup_signal_frame() relied on the fact that vregs and the signal stack code
is a multiple of 4 bytes in size.
* Fixed sigaction(): it did return the error code directly instead of setting errno.
* signal() actually had a work-around for the broken sigaction()...
* Replaced the sig_func_t typedef with a sighandler_t typedef - this is non-standard
anyway, but now we're at least compatible with the GNU world instead of introducing
our own solution (BSD seems to use sig_t here, BTW).
* Removed now unused sigval structure from the header; it should be added again as
soon as we start supporting it.
* SA_RESETHAND and SA_ONESHOT are the same thing; the former did not work before.
* Made the non-standard SA_* flags refer to the standard ones instead of the other
way around.
* Added a test application for various signal features - works fine under Haiku,
tested also under Linux and BeOS (the latter fails as it does not support SA_RESTART).
More tests should be added, though.
* Cleanup.

* Added KMessage to the runtime_loader (a bit hacky, though) - it will use
it to deliver the above mentioned functionality.
* load_dependencies() did return the wrong status code in case a library
was missing; now it returns B_MISSING_LIBRARY.
* load_dependencies() will now try to load all dependencies when a report
message is requested; therefore, all missing libraries are listed.
* Renamed uspace_program_args to user_space_program_args.
* The kernel filled in various members of the user_space_program_args structure
unsafely, ie. was not using user_memcpy().
* Renamed some local variables in team.c to better fit our style guide (ie.
uargs to userArgs).
* Changed Tracker to use the new _kern_load_image() variant on Haiku to retrieve
and report all missing libraries. This fixes bug #1324.

This does prevent the unwanted side effect of reading or writing at the current
file pointer position when the functions are called with a -1 position.
It's save to do this check in user space, because calling the _kern_* function
with -1 pos has the same effect as calling the normal read/write posix functions.

the team enters the debugger. Handy in situations when the program in
question can't really be started in a debugger (or it would be
complicated to do so). The functions work only as long as no debugger is

We clear the arch specific team and thread debug infos now, when a new

size has a different size). We now always only return the R5 stat structure here.
This fixes bug #420. We might want to find a different solution to this problem,

The test application lets run a thread at the highest priority that calls
yield all the time - the system stays responsible when it runs, so it seems
to work fine :)
Changed the malloc implementation to use _kern_thread_yield() instead of
snoozing.
We should think about making this call public, too.

The time base conversion factor is the 32 bit value
2^32 * 1000000 / time base frequency,
so the system time can be computed by
system time = time base * conversion factor / 2^32.
The expression in system_time() looks more complicated now, but is
actually much faster (factor 2.5 on my Mac mini). I'm positively
surprised, how good the assembly looks, that GCC 4 generates. There's
not that much potential for optimization by hand-coding the function.

available under R5).
The solution is a bit messy, but we have to live with it :-)
The runtime loader now patches the __gRuntimeLoader symbol in libroot.so to point
to its exported structure instead of passing it to the init functions as an
argument.

device in the Open Firmware implementation of boot loader and
pass its path to the kernel, where it's opened and used for
getting/setting the real time. The expensive atomic_*64() on PPC
32-bit make things a bit more complicated. Moreover, missing
64 bit multiplication and division instructions won't really
allow system_time() to be anywhere near as fast as on x86. :-/

substructure now (that's the only member actually). The system time
offset is therefore accessed via architecture specific accessor
functions.
Note, that this commit breaks the PPC build. Since I want to rename at
least one file I've already changed, I can't avoid that.

in out of memory quite fast.
We don't shrink the heap (yet), but at least we can reuse the memory that
was freed by Hoard (it doesn't just remove bytes from the end, it will also
free up smaller parts in the middle).

* Pulled the architecture specific part out of <posix/setjmp.h> into
<posix/arch/<arch>/arch_setjmp.h>.
* Moved setjmp_save_sigs.c from the x86 specific implementation into a
"generic" sibling directory, since it is reusable (and actually used
by the PPC implementation).
* Added generic/longjmp_return.c containing a function __longjmp_return,
which is invoked at the end of siglongjmp(), resetting the signal mask
and validating the return value. It is used by the PPC implementation,
and should also be used by the x86 implementation, but I'll leave that
to someone who's motivated enough to also test it. :-)

functions from glibc 2.3.2. Adding those one by one is extremely
boring and time-consuming work. We should probably just remove the
math stuff again, add a verbatim copy of the glibc directories, and
shuffle things around afterwards.
* Note that for x86 holds sizeof(long double) == 96. I removed the
generic 128 bit long double functions that were in use before and
added respective 96 bit versions to arch/x86 (or left them out, if
they weren't used). For PPC the System V ABI spec supplement specifies
sizeof(long double) == 128, but I had trouble configuring gcc to
actually use that setting (looks like there simply is no support for
TI mode for PPC 32). So we have to live with sizeof(long double) ==
sizeof(double) == 64 for the time being.

x86 the Haiku image still builds, so it is apparently not used. I
guess it would be best to abandon our posix_math.o completely and
use the glibc math implementations instead.

categories:
* Missing includes (like <stdlib.h> and <string.h>).
* Linking against $(TARGET_LIBSTDC++) instead of libstdc++.r4.so.
* Local variables shadowing parameters.
* Default parameters in function definitions (as opposed to function
declarations).
* All C++ stuff (nothrow, map, set, vector, min, max,...) must be imported
explicitly from the std:: namespace now.
* "new (sometype)[...]" must read "new sometype[...]", even if sometype is
something like "const char *".
* __FUNCTION__ is no longer a string literal (but a string expression), i.e.
'printf(__FUNCTION__ ": ...\n")' is invalid code.
* A type cast results in a non-lvalue. E.g. "(char *)buffer += bytes"
is an invalid expression.
* "friend class SomeClass" only works when SomeClass is known before.
Otherwise the an inner class with that name is considered as friend.
gcc 4 is much pickier about scopes.
* gcc 4 is generally stricter with respect to type conversions in C.

Library names are now mapped for all targets but "host" (not only for
"haiku") -- added one more level of indirection to achieve that.
(TARGET_LIBRARY_NAME_MAP -> *_LIBRARY_NAME_MAP_*).
* Renamed build/HaikuBuildCompatibility.h to BeOSBuildCompatibility.h
(auto-included when compiling something that uses the Be API for platform
"host" on anon-BeOS platform), and introduced build/HaikuBuildCompatibility.h,
which can be included when compiling something that can be built for both,
Haiku and BeOS compatible platforms.
* Introduced libhaikucompat.a, a library that adds a few functions existing
under Haiku, but not under BeOS.
* New rule AddSubDirSupportedPlatforms.
* Renamed libopenbeos.so to libbe_haiku.so.
* Introduced new target platform "libbe_test", which is basically equivalent
to a BeOS compatible host platform target, with the exception, that instead
of the host platform's libbe.so a special build of Haiku's libbe.so
(libbe_haiku.so (formerly known as libopenbeos.so)) is used. Furthermore
Haiku's public app, interface, storage, and support kit headers are used
when compiling. This replaces the less nice way in which the test app server
and applications for this test environment were built.
When building for platform "libbe_test", the library name "be" is
autotranslated to "libbe_haiku.so". Thus most applications don't need
special fiddling when them building them for the app server test environment;
usually an "AddSubDirSupportedPlatforms libbe_test ;" will suffice.
* Reduced the dependencies of <syscalls.h> and fixed problems caused by this
(e.g. source files not including the needed headers directly).

to the parameters nor the number of parameters; the kernel is able to
get both without problems.
The syscall functions in libroot (_kern_*()) are now self-contained
(they don't "jmp" to separate code anymore), which at least
theoretically allows gdb to print a stack trace with the syscall
function on the top when a thread is currently performing a syscall.
Practically it doesn't work yet, though, since those functions are
frameless (i.e. create no stack frame) which needs special support
I haven't implemented yet.

To avoid doing a syscall for find_thread(0), the assembly
version is now in libroot. For BeOS R5 compatibility,
_kfind_thread_ is retained. This will fix some compile

versions.

Also, both functions will now test if the executable exists and is valid; that
way, load_image()/exec*() can catch many errors without having to create a new

The runtime linker now exports a function to test executables that is aware

following 1152 MB - that area only guarantees that the heap can grow this much before
the application need the memory for something else. And even then, the heap range
is reused from top-to-bottom, allowing for maximum heap usage. Of course, if the
memory after the heap range is not claimed yet, it can still be claimed by the heap,
too. Added new syscall to create the reserved range.
Fixed a bug in vm_delete_areas(): when it removed reserved areas, the area list
