a flattened argument/environment buffer now. This simplifies the work
for the kernel a bit, since it can just copy the buffer and check
whether it looks OK instead of messing around with individual strings.
The runtime loader also gets a flattened array.
* Set the maximum size of the arguments/environment buffer to 128 KB.
When more arguments are passed, we fail with a proper error code
(instead of just truncating the arguments as before).
* On exec*() the first argument was silently replaced by the given path
name, which is not correct.

respectively other gcc version on a Haiku compiled with gcc 2 or gcc 4.
The libraries for such an executable are first searched in "gcc4"
respectively "gcc2" subdirectories of the standard search path
directories. If not found there, we try again with the standard paths.

to contain headers shared by kernel and userland (mainly libroot).
* Moved quite a few private kernel headers to the new location. Split
several kernel headers into a shared part and one that is still kernel
private. Adjusted all affected Jamfiles and source in the standard x86
build accordingly. The build for other architectures and for test code
may be broken.
* Quite a bit of userland code still includes private kernel headers.
Mostly those are <util/*> headers. The ones that aren't strictly
kernel-only should be moved to some other place (maybe
headers/private/shared/util).

trace levels.

what one usually wants.

and defines the macros needed by them.
* Renamed syscall sys_vm_map_file() to _kern_map_file() and changed the
path to an FD parameter. Changed vm_map_file() accordingly and
adjusted the kernel ELF loader and the runtime loader.
* Added syscall _kern_unmap_memory().
* Added bool unmapAddressRange parameter to vm_create_anonymous_area()
and map_backing_store(). If true and the address specification is
B_EXACT_ADDRESS, all areas in the specified address range will be
deleted (unless an area is covered only partially).
* Introduced B_SHARED_AREA flag, which is set on areas that have been
created by {vm,_user}_map_file() with REGION_NO_PRIVATE_MAP. When
fork()ing those areas won't be copied CoW, but rather be cloned. This
is needed for mmap() MAP_SHARED.
* {vm,_user}_map_file() also accept an FD argument < 0, in which case an
anonymous area is created.
* Implemented mmap() and munmap(). Currently there's the restriction
that we can't partially unmap areas. Otherwise the functions should be
rather compliant. We also support the non-POSIX extension
MAP_ANONYMOUS.

finally created a solution to avoid that: Header files that contain
configuration settings (and nothing else) go to build/config_headers.
To change settings, create a directory build/user_config_headers (which
is ignored by svn), copy the respective header there and modify it at
your leisure. Currently only tracing_config.h has been moved to the new
location, but more files will follow eventually. It is also recommended
to move optional macro definitions in Jamfile (as for BFS) to a config
header instead; the build system will then automatically rebuild on
changes.

depending on the gcc version of the executable.
* Adjusted non-BeOS-style symbol resolution so that add-ons and
dynamically loaded libraries find symbols in the executable.
This change re-enables support for undefined symbols.

shared object to find out the GCC version it has been compiled with.
This is not an exact science, since we've got the version string for
every single object file that has been linked in, but my heuristic seems
to be good enough.
Having the gcc version at hand will allow for two features: Enabling
work-arounds for old executables (like the type info problem in BeOS
apps), and automatically selecting the right set of libraries in a mixed
gcc 2/gcc 4 environment.

instead, which also handles the root case correctly.
* The user and group arguments of test_executable() aren't needed any
longer.

The runtime loader did not correctly resolve %A correctly with the
actual normalized program path. IOW it would not work correctly with
symlinks to applications that had their own lib directory.

some absolute path was not enough to always recognize a library as
already loaded. This fixes problems with Perl where loading an add-on
would cause another instance of libperl.so to be loaded, which would
lead to crashes due to uninitialized static vars in the new instance.
Perl builds now and the tests run, but quite a few do fail.

* Fixed off by one error in the matching loop of the cleanup hook
* Make sure we successfully acquire the locking sem of the exit stack

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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23486 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Changed ResAttr rule to allow not deleting the file before writing the
attributes.
* Added application signatures for the runtime_loader and zbeos, just so that
they may have an icon, too (hint, hint) :-)
* As a side effect, this also let's FileTypes handle these two as apps (even
though they aren't), so that I can close bug #606.

* This also fixes starting the runtime loader directly: it no longer crashes
but will just return an error.

therefore, we could remove the ugly defines from KMessage again, and compile it
with KMESSAGE_CONTAINER_ONLY.
* Added KMessage::SetDeliveryInfo() to be able to send messages with a correct
header.
* Fixed a bug in KMessage::SendTo() that would not send the senderTeam when passing
a negative value for the parameter, but override it when passing in a valid
value.

for _kern_load_image().
* 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.
* Adapted kernel_cpp.cpp to the runtime loader as well; the latter will now
compile with _LOADER_MODE defined.

and ADDON_PATH already were).
* This closes ticket #1103.

* The previous symbol resolution code was incorrect. It would search all
loaded images in the order they had been loaded. Thus an add-on would
possibly see a symbol of an earlier loaded add-on. Now we search
recursively starting with the respective root image (executable or
add-on).
* Added BeOS style symbol resolution and made it the default. A symbol
undefined in an image is only searched in its direct dependencies.
Fixes bug #889 (BeOS apps crashing under Haiku when opening a file
panel).

* This sane heap revealed a bunch of bugs (like sLoadedImageCount not being
maintained that was used for various allocations).
* If the allocation of the image fails, opening the app will now just fail
instead of crashing of overwriting random data (IOW VLC will now load
okay, but cannot load some of its add-ons anymore).

issues:
* Our glue code was broken after all - it allowed Haiku apps to start under
BeOS (and vice versa), but the initialization/termination functions were
called with an invalid image ID - on *both* sides! As it turns out, the
Be glue code did *something* with %ebx, but certainly didn't put the image
ID in there, but just passed it on the stack, as we did before (just in
the wrong order...). Therefore, the arch_call_init_term stuff is not
necessary.
* When unloading add-ons, their termination functions were never called, as
the image (for get_image_symbol()) was already made inaccessible, and
therefore the symbol couldn't be found.

another chance and search them in the standard search paths. This fixes bug #601 and lets
Becasso run on Haiku.

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

To avoid doing a syscall for find_thread(0), the assembly

_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
of the search paths, and will also check user permissions upfront.
