* The functions now check the acquire_sem() result.
* mem_freetag() will return an status code now, too.
* Moved the mem_block and mem_info definitions into the source file; no
reason to have them public.
* You can now give the memory manager a name which it will use for its
heap area and lock.
* Minor cleanup.

* some fixes to make screen_blanker wait_for_thread() instead of
killing the screen saver thread, BScreenSaver::Stop() is now called
as well as its destructor

is managed for those bitmaps:
- the shared client memory mechanism is used to allocate a small overlay_client_data
structure that contains the actual buffer and a semaphore that you have acquire in
order to access it.
- LockBits()/UnlockBits() now have a function: you need to call them before accessing
the overlay buffer, and you need to keep that lock until you're done with it.
* The overlay cookie is now an extra member of the ServerBitmap class.
* Removed fInitialized from ServerBitmap - IsValid() now just checks the buffer associated
with the bitmap.
* ViewLayer::Draw() will now handle overlay bitmaps specially and will draw the overlay
color instead of any contents (this is currently in ugly pink, but will become some
dark color later on).
* All what's missing from actually being able to use overlays now is to configure
them so that they are shown on screen. VLC will now show an empty pink window when
overlay video is enabled.

via the graphics driver (but not yet shown on screen).
I probably got the meaning of the "overlay count" wrong - I guess that you
can allocate any number of overlay bitmaps, but can only see "overlay count"
on screen at a time (right now, I only allow to create "overlay count" bitmaps).

This fixes a locking problem in BFS where one thread tried to acquire two read
locks (where someone else trying to acquire a write lock would have caused a
dead lock).

to cut down on BRegion related allocations, cannot really tell
if it speeds things up
* used the new BRegion pool in WindowLayer and ViewLayer whereever
a BRegion was used on the stack
* fixed the debugging stuff in MultiLocker - it will get you into
the debugger if you
- try to nest read locks
- try to write lock when your are a reader already
- don't match up nested locks when your a writer
-> but only if you #define DEBUG 1 in the .cpp, is off by default now
* went over WindowLayer, ServerWindow, Desktop and a few other places
and fixed the locking for use with the MultiLocker, the "a reader can
not become a writer" is especially tricky, feel free to review the
changes
* activated the MultiLocker, I tested this quite a bit, if there are
problems simply turn on DEBUG and you should drop into the debugger
right where the problem is... hope all is good

as well.
* Some minor cleanup.

it and rebuilding it on the server side (that causes a huge speed
up for regions containing many rects)
* There is a method in ServerLink that could have been used, but I
actually needed to add the direct BRegion support to LinkReceiver
* added LinkReceiver as a friend to BRegion class
* ServerApp and ServerWindow keep the CursorManager locked after they
have retrieved a cursor until they have called Acquire() on the
cursor. (Axel: what good is using atomic* stuff in Acquire() and
Release() if we have to protect this by a lock anyways?)

* Renamed elf.c to elf.cpp and fixed warnings.
* Renamed elf_image_info::dynamic_ptr and eheader to dynamic_section and elf_header.

At this point, this driver only works on Haiku, the R5 app_server is crashing for some

BRect to clipping_rect with simple C casts. I think this
is more adequate, since clipping_rects are used for
pixel indices. This change fixes some graphics problems too,
it appears that cursor coords are fractional on Haiku, even
with a normal mouse. In Playground, this resulted in the
hit points being rendered wrongly.

* Removed private color set functions from InterfaceDefs.cpp - we might want
something similar, but definitely not like that.
* Minor cleanup, added some missing licenses.

* Removed ServerMemIO class, was never used.

all teams in serveral server areas, and instead of having to eventually clone
them all several times in BBitmap, we now have one or more areas per team,
and BBitmap will only clone areas once if needed. As a side effect, this
method should be magnitudes faster than the previous version.
* This method is also much more secure: instead of putting the allocation
maintenance structures into those everyone-read-write areas, they are now
separated, so that faulty applications cannot crash the app_server this
way anymore. This should fix bug #172.
* Freeing memory is not yet implemented though! (although all memory will
be freed upon app exit)
* There are now 3 different bitmap allocation strategies: per ClientMemoryAllocator
(ie. via ServerApp), per area (for overlays, not yet implemented), and using
malloc()/free() for server-only bitmaps.
* ServerBitmap now deletes its buffers itself.
* Cleaned up BBitmap and BApplication a bit.
* The test environment currently doesn't build anymore, will fix it next.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16826 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added a vfs_free_unused_vnodes() function that calls the low memory handler
directly.
* create_sem_etc() now calls the above function in case there are no semaphores
available anymore; this usually frees up to 2 semaphores per node (one from
the cache if there is a file cache attached, and eventually one from the
file system).

or vm_cache_ref couldn't be created, instead of cleaning up and returning

* vm_cache_ref_create() no returns a status_t instead of the vm_cache_ref
(as that's part of the vm_cache anyway).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16602 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added some comments
* Added some checking to avoid noop shifts
* Added buffer length checks
* Implemented (as Stephan suggested) a version of ConvertBits() that takes offsets.
This new version allows to move a region of the source into a region (possibly not at the same point) on the dest while converting colorspaces on the fly.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16592 a95241bf-73f2-0310-859d-f6bbb57e9c96
that put one or more full paths on the stack before, which could cause some

* Desktop::ActivateWindow() no longer crashes in case the window to be activated
is not on the current workspace - instead, it doesn't do anything at this
point. IOW it doesn't handle workspace activation at all, yet.
* Renamed ServerWindow::GetWindowLayer() to ServerWindow::Window().
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16550 a95241bf-73f2-0310-859d-f6bbb57e9c96
* AS_GET_STRING_WIDTHS now uses this method to send the strings to the app_server;
ie. it no longer sends the whole strings, and it saves sending the string length
separately.
* BFont::StringWidth() will now always return 0.0f in case of an error (instead of
some random value)
* Minor cleanup.

* all cursors owned by a team are visually different,
or (iaw) an already existing cursor is reused when
it is set by the client again
* changed various occurances of cursor data from "int8*"
to "uint8*"
* ServerCursors also remember the R5 data from which
they were created
* the reference counting and destruction of
ServerCursors changed: The cursor knows it is attached
to a CursorManager and one can simply use
ServerCursor::Acquire() and Release() and the reference
counting and everything is being taken care of
* destroying a ViewLayer will now correctly release a set
ServerCursor
* fixed a race condition when setting a cursor through
BView::SetViewCursor(): If the client code looks like this:
BCursor cursor(cursorData);
someView->SetViewCursor(&cursor, false);
there is a relatively high chance the BCursor destructor
told the ServerApp thread to destroy the cursor before
the ServerWindow thread got to "acquire" the cursor for
use by the view layer. The very same problem is likely the
reason that SetViewCursor works to unreliably on R5, even
when the "sync" flag is set to "true" (although it should
theoretically work in that case).
all these fixes make WonderBrush work fine again with the
new support of custom cursors.... coded by axeld and myself

* Reordered some functions
* Area messages can now be unflattened instead of using the private _Reference and a special port code
Passing by area is now mostly working but it's not yet enabled. I will have to conduct performance tests first to see if and starting at what messagesize the overhead is reasonable.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16500 a95241bf-73f2-0310-859d-f6bbb57e9c96

The data itself is now checksummed too (unlike R5 where only the header gets a checksum). This might be a performance problem for larger messages. Opinions?
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16482 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Introduced a _SetStringValue() to avoid code duplication.
* The string types now check the original value, and don't write anything if the
contents stay unchanged (with the current exception of the sniffer rules).
* The monitor notfication methods no longer "clobber" the status result.
* Major cleanup.

* AS_LAYER_DELETE now gets a token, no longer frightening choice of parent.

Input server now saves keyboard typematic settings whenever they are modified,

Same problems might apply to mouse and keymap settings.
Input server shutdown handling should be reviewed.

* Reworked functions like GetEscapements(), GetBoundingBoxesAsString() and GetGlyphShapes() completely
* Made the ServerFont functions uniform in their prototypes and cleaned out unnecessary arguments
* Added new UTF8 handling functions to moreUTF8.h that are now used by ServerFont

In other words, ServerFont is now cleaned and handles UTF8 pretty efficiently. Some ToDo's are still left though.

deleting objects that don't belong to the one deleting them (hello HWInterface!)
* Almost all ServerWindow cursor stuff was broken; I've replaced all commands
to set a cursor with a single one AS_SET_CURSOR.
* Renamed some cursor commands.
* Changed the (broken) way ServerApp::fAppCursor was maintained - the application
cursor is now NULL as long as possible.
* Removed superfluous ServerCursor app signature stuff.
* The BApplication will no longer duplicate the default/I-beam cursors, it will
just reuse the default ones which now have fixed tokens.
* As a result, changing the cursor is now working as expected, closing bug #102.
* Rewrote Cursor.h, renamed private members to match our style guide.
* Minor cleanup.
What's still left to be done is reference counting the cursor objects to make them
work right and reliable.

* scheduler.c::sRunQueue::tail was not maintained at all; changed sRunQueue to

The test application lets run a thread at the highest priority that calls
