+ Fixed an error with disk_scanner_get_partition_fs_info() that was causing
the fs module to not be unloaded when identification succeeded. The next
time around, get_module() was returning B_OK, by the module pointer was
being set to NULL. I'm not sure if this is the expected behaviour of the
emulator, so we may want to investigate.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2286 a95241bf-73f2-0310-859d-f6bbb57e9c96
Changed fd.h inlines because team->ioctx is now team->io_context.

Also replaced the linked lists in the BufferManager (which were complicated,
but working ok) with template based ones.

implementation that was buggy, not very flexible, and incomplete.
Changed some variable types, and function names.

added detection of and cleanup after application crashes.
if the media_addon_server crashes, it will be restarted.
removed preleminary volume control functions.

* People interested, please review!
* This is based on the patch from Fredrik Moden which was based on
the Oleg Krysenkov one.
* The original patch has been reworked by myself.
* Adapted the code to work with the new PluginManager API which
differently than before doesn't need to contact the media_server.
* BMediaRoster is now capable to know which nodes are
instantiated in this team. This is also a first step to make
them survive after media_server crashes.
* A control at BMediaRoster::Quit can notify if all nodes
were correctly released. Ideally at this point the local nodes
list should be empty.
* If the same shape alpha mask is set again and again, we now keep
the rendered masks in a cache. On certain websites, WebKit sets
the same shape for clipping hundreds of times, which uses a lot
of time to render the masks.
* When a shape mask was generated, we put it into AlphaMaskCache.
The constructor for ShapeAlphaMask is made private and a factory
method is used for instantiation instead, which transparently
looks up in the cache whether a suitable mask was already generated
before (so the entire caching is encapsulated inside the AlphaMask
class).
* When taking a mask out of the cache, we still create a new
AlphaMask instance. However, the new instance will share the
mask bitmap with the previously generated instance (aside from
the rendering of their bitmap, AlphaMask instances are pretty
lightweight). Shape masks are only seen as identical when
their shape is the same, the inverse flag, and they have the
same parent mask.
* Cache is limited to a fixed size of currently 8 MiB, using a
simple random replacement scheme. An LRU scheme can be added in
the future if necessary. Counting of bytes for the cache size
includes parent masks of masks in the cache, even if the parent
itself is not cached. A reference counter for "indirect" cache
references keeps track of which masks are not part of the cache,
but still need to be added to the cache byte size.
* For now, only for ShapeAlphaMasks, other mask types can be added
as necessary.
* Since the last change, the user launch_daemon would talk to the
registrar again.
* However, this also caused BRoster::Launch() to preregister the app,
which messed up our preallocated port.
* BRoster::Private::Launch() now allows to get the port that the
registrar created in such a case, and the launch_daemon will now just
use that one as default port.
* This lets us talk to the Deskbar again, and should fix#12455, as
well as #12454 (again).
* BView::TranslateBy(), BView::ScaleBy() and BView::RotateBy()
allow to conveniently modify the current affine transformation.
This makes it unnecessary to first read the current transform,
modify it, and then set it again.
Uses the new Pre...() methods of BAffineTransform.
* Also, remove setting the transform "through" to the BView even
while recording a BPicture, as this now results in transforms
being applied more than once.
* Add new clipping API for rectangles (ClipToRect, ClipToInverseRect)
and shapes (ClipToShape, ClipToInverseShape)
* Works with affine transforms and automatically switches from fast
region-based clipping to alpha-mask based clipping as necessary.
* Always self-intersecting, i.e. no state push required to further
narrow down the clipping region. All of the 4 new methods can be
mixed in any order.
Conflicts:
src/kits/interface/PicturePlayer.cpp
src/servers/app/ServerPicture.cpp
In addition, the following files were also adapted to master branch
BPicture changes during the merge:
src/kits/interface/PicturePlayer.h
src/servers/app/PictureBoundingBoxPlayer.cpp
* Added B_ prefix.
* Renamed 16 bit variants to B_LENDIAN16_*.
* Added 32 bit variants (albeit only 16 of them for now).
* Adjusted headers that were using them.
Reduce duplication of code by
* Removing from elf_common.h definitions available in os/kernel/elf.h
* Deleting elf32.h and elf64.h
* Renaming elf_common.h to elf_private.h
* Updating source to build using public and private ELF header files
together

* Ie. a listing of all targets/jobs, as well as specific (basic) info
on each.
* Also added a bit of optional debug output.
* Moved translating the path to launch time -- we should take the job's
environment into account here at some point.
The use of an unreliable test for relocatability effectively broke
runtime_loader's support for non-position-independent executables, as it
would insist on randomly positioning these files' segments in memory
anyway causing the program to quickly crash.
With this change runtime_loader uses the object type specified in the
file's header to determine whether its segments can be safely relocated,
restoring support for non-PI executables.
Fixes#12427.

Fixes#11990, most of the changes had already been done.
* Make test-app_server work again in a launch_daemon environment
* test_registrar gets a separate signature and port name again so the
host system can distinguish it from the system registrar
* AppServer is normally a BServer now, however, there can't be two
BApplications in one team. A class TestServerLoopAdapter is added,
which becomes the base class of AppServer instead of BServer when
compiling for libbe_test. It's an adapter class which looks towards
AppServer as it if was a BServer, but internally it is derived from
MessageLooper (like the old AppServer before the transition to
BServer).
This way, AppServer can stay a BServer in normal builds and it also
avoids having to use too many #ifdefs to distinguish the two
versions.
* Add new methods
BView::BeginLayer(uint8 opacity)
BView::EndLayer()
* All drawing between begin and end of a layer is redirected onto an
intermediate bitmap. When ending the layer, this bitmap is
composited onto the view with the opacity given when the layer was
started.
* Layers can be nested arbitrarily and will be blended onto each
other in order. There can also be any arbitrary interleaving of
layer begin/end and drawing operations.
* Internally, drawing commands are redirected into a BPicture between
BeginLayer and EndLayer (but client code need not know or care
about this). Client code can also start/end other BPictures while
inside a layer.
* Uses the PictureBoundingBoxPlayer to determine the size of the
layer bitmap before allocating and drawing into it, so it does not
allocate more memory than necessary and -- more importantly -- it
will not alpha-composite more pixels than necessary.
* Drawing mode is always set to B_OP_ALPHA, blend mode to
(B_PIXEL_ALPHA, B_ALPHA_COMPOSITE) while inside layers. This is
necessary for (a) correct compositing output and (b) for
redirection of drawing into the intermediate bitmap, which uses the
renderer_region offset (in B_OP_COPY, the Painter does not use the
AGG renderer methods, it directly accesses the pixel data. This
would access out-of-bounds without the offset, so B_OP_COPY cannot
be allowed.)
To ensure these modes aren't changed, BView::SetDrawingMode()
and BView::SetBlendingMode() are ignored while inside a layer.
* The main motivation behind this new API is WebKit, which internally
expects such a layers functionality to be present. A performant and
reusable implementation of this functionality can only be done
server-side in app_server.
Broke binary compatibility for the notify_select_event(), since it obviously
hasn't been used on R5 at all.
The new API/implementation is much nicer to use.

Renamed sys_read_stat() to sys_read_path_stat() - sys_read_stat() is now
the fd operation.
Removed the sys_write_attr_stat() call because it is no longer needed.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1554 a95241bf-73f2-0310-859d-f6bbb57e9c96
Changed the file_descriptor structure (more status_t, name removed).
Changed "extern inline" to "static inline" in thread.h/arch_thread.h as those
also work with -O0 -g.
Added prototypes for [arch_cpu_]user_strlcpy().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1454 a95241bf-73f2-0310-859d-f6bbb57e9c96
Changed lock.h to like those changes.
Moved the create_sem_etc() from the public OS.h to the private kernel only
sem.h, cleaned it up a bit.
gcc doesn't seem to like the "extern inlines" with -O0 -g, so I replaced
an inline function in thread.h with "static inline" (which it does always
like).

Replaced "int" with "int32" for the id types.
Removed some stuff from ktypes.h because it didn't belong there.

+ Modified BMimeType::SetSupportedTypes functionality so it keeps track of
stranded types (i.e. previously supported types that have not had the now
unsupporting app signature removed from their supporting apps list yet due
to a false fullSync parameter) over consecutive SetSupportedTypes(...,
false) calls and updates all appropriate stranded types on the next
SetSupportedTypes(..., true) call.
+ Added fullSync parameter to BMimeType::DeleteSupportedTypes
+ Made BMimeType::Delete() do a DeleteSupportedTypes(..., true) call to
properly update the supporting apps lists when a mime type is deleted.
+ Added initial BMimeType::Get/SetSnifferRule
+ Updated BMimeType::CheckSnifferRule() to return B_BAD_VALUE when passed
a NULL rule string.
+ Brought CheckSnifferRule() tests up to date
+ Added lots of Mime::Database doxygen

needed if I wanted to keep things clean and managble.
storage/MimeDatabase.{h,cpp} have been broken into:
storage/mime/database_support.{h,cpp}

+ get_icon_data()
storage/mime/Database.{h,cpp}

non-atomic read, and mime monitor functionality.
storage/mime/InstalledTypes.{h,cpp}
+ Helper class for Mime::Database::GetInstalled[Super]Types()
storage/mime/Supertype.{h,cpp}
+ Helper class for Mime::InstalledTypes
I haven't merged my intial, somewhat cludgy GetInstalled[Super]Types
implementation into the new setup yet. That comes next, and it ought
to be a more graceful implementation now.
I also implemented BMimeType::Get/SetSupportingTypes(), though
they haven't been tested yet (sorry).

- {Get,Set}AppHint()
- {Get,Set}Icon()

SetIcon() is currently not implemented as I would like,
due to us needing an OBOS::BBitmap implementation.
Thus there are two versions and the GetIconData()
function until that day comes around.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@818 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added syscalls for, and implemented sys_create_link(), sys_remove_dir().
Implemented link(), unlink(), rmdir().
Fixed the inconsistent path buffer handling in the user|sys vfs functions; the

null byte).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@748 a95241bf-73f2-0310-859d-f6bbb57e9c96
Replaced the unused syscall for getdtablesize() with one for access().
Implemented sys_access() and added it to the file system interface.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@662 a95241bf-73f2-0310-859d-f6bbb57e9c96
+ Fixed a bug with 0eXXX floats being handled improperly
+ Updated a few error messages to give proper character
stream positions.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@650 a95241bf-73f2-0310-859d-f6bbb57e9c96
+ Added support for extended notation floating point numbers,
as well as signed (+ and -) floats.
+ Finished up parsing code
+ Moved Err class into it's own header/source pair, since I
started using it all over the place in the sniffer code.
+ Did my darndest to make sure I wasn't leaking memory
anywhere.
+ Matched up error messages as best as possible with R5's
error message. Some couldn't be matched, some were improved.
There *are* a few things left to do. I don't think priorities are
verified to be valid (0.0 <= x <= 1.0). More tests also need to
be written. Things have solidified enough now that documentation
is a reasonable thing to start considering as well.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@608 a95241bf-73f2-0310-859d-f6bbb57e9c96
+ Added Priority()

+ Replaced ExprList typedef with plain old std::vector<Expr*>
so I wouldn't forget what the hell kind of list I was working with.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@607 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added a "mode" parameter to the sys_create_symlink() function.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@591 a95241bf-73f2-0310-859d-f6bbb57e9c96
- added needed syscalls to access symlink support from userland
- implemented lstat(), symlink(), and readlink()
- added dev_t to ktypes.h (for now - should be in a public header anyway)
- added symlink support to the "ls" command (now calls lstat() and shows the
link target with the -l option)
- changed the sys_read_stat() call to support symlinks, and updated files
using that function (it gets an extra argument: bool traverseLink)

A couple of changes in various interrupt and thread functions and structures.
These make it now possible to change the stack at any time without making the kernel crash. This is needed for calling VESA 3.0 VBE functions through the protected mode interface.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@422 a95241bf-73f2-0310-859d-f6bbb57e9c96
Fixed many bugs.
Now, the vfs_ prefix is for functions that are called by other parts of the
kernel. file_ is for file related stuff, dir_ for directory related, and
common_ for both, fs_ for general file system stuff.
Put all prefixed functions together in the source.
Implemented (currently without a user/sys call) opening/creating of entry_refs,
and node_refs (the latter for opening directories only).
Moved vfs_dup(), and vfs_dup2() to fd.c, fd_dup(), and fd_dup2().

there and confused issues somewhat.
- add the kerrors.h file that has kernel only error codes, namely the
ERR_ codes from newos.
