* Use the common 0xfffd character as a substitute for invalid characters
* Corrected comment
This function is used by the app_server to convert the UTF8 strings to char
codes to feed FreeType. Using a non space substitute character at least for
now, as it makes it more obvious where invalid characters are present.
I tested this change with some UTF8 test files and it seems to work well.

breaking out of the loop too early, and would therefore miss the last
character.
* Replaced UTF8CountChars() with a short and safe version as well.

of stuff. I think the trouble is that you keep decrementing charCount while
still inside the same UTF8 glyph. I cannot really tell, I am hoping you don't
mind me reverting to the old version, since the new one is only three lines,
so it should be easy to correct and re-commit.

to retrieve the default settings for the netmask/broadcast depending on the
specified address/netmask.
* interface_protocol_control() now uses this to reset the broadcast/netmask
to their default values on SIOCSIFADDR resp. the former only on
SIOCSIFNETMASK.
* This fixes bug #1861.

* driver_entry::api_version now stores the actual version instead of a
pointer to it.
* Renamed node_path_entry to path_entry and reused it for driver
reloading: handle_driver_events() will now also check for drivers to
add in the sDriversToAdd list.
* Added new devfs_driver_added(), and devfs_driver_removed() functions
that trigger certain driver actions.
* Implemented notifying devfs on B_ENTRY_CREATED, B_ENTRY_REMOVED, and
B_ENTRY_MOVED events in probe.cpp. The watched directory inode numbers
are now stored in a hash for B_ENTRY_MOVED.
* unpublish_driver() did not actually delete the node, it only marked
it removable since we never get/put the node. We now do, and so the
node is actually removed as intended.
* Added "devfs_driver" KDL command.
* Minor cleanup.

workspaces view can now be any view in the hierarchy.
* Added private view flag kWorkspacesViewFlag that identifies such a
view - note though, that you must not remove a view before closing or
hiding its window for now (and that you still need to set the
kWorkspacesWindowFlag, too).
* Fixed Workspaces check for valid screen coordinates; after a crash, it
managed to open its window offscreen for me.
* Added a ViewLayer method FindView() that finds a view with the
specified flags set.

* Added team::flags. Currently only used for setting a flag when a team
has exec()ed.
* Some improvements of _user_setpgid():
- It failed incorrectly when the target process was a process group
leader. According to the standard it shall fail when the process is
a session leader. Moving a process group leader to another process
group is fine, even if that leaves the group leaderless.
- Fixed race conditions. We need to recheck the error conditions when
we hold the team spinlock. Otherwise the situation could change
while we allocated the new process group. This was one of the
reasons for bug #1799 -- after the shell fork()'s both parent and
child invoke setpgid() for the child.
- Fixed behavior for pid == pgid. It doesn't necessarily mean that a
new group has to be created.
- Fixed update of target process group orphaned state.
- Squashed TODO: setpgid() on a child is supposed to fail after the
child has exec()ed.

This eliminates the edge case where the grow thread would not be able to create
a new area because no memory could be allocated for the allocation of the area.
As this case cannot happen anymore, it is also not possible to deadlock in
memalign. Therefore the timeout (which would only have prevented the deadlock
but wouldn't have solved the edge case anyway) has been removed too.
Add options to dump the dedicated grow heap and to only print the current heap
count to the "heap" debugger command.

but there's a special handling for 0 us relative timeouts. Syscalls
usually return B_WOULD_BLOCK instead of B_TIMED_OUT in this case, and
callers might explicitely check for it. Hence we don't convert 0 us
timeouts anymore. gdb works again.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23989 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added syscall restart support for connect(), accept(), send(), recv(),
which are implemented via ioctl()s. The actual restart support is done
in the net stack driver's ioctl() hook. Lower layers need to correctly
deal with socket timeouts, though, for which the stack module provides
support functions.
* TCPEndpoint::_WaitForEstablished() does abort now when an error
occurred earlier, so that trying to connect to an unused port fails
immediately, as it should.
* Fixed and refactored TCP connection reset handling. The new
TCPEndpoint::_HandleReset() does the job. Got rid of
TCPEndpoint::fError.
* Fixed sequence numbers for SYNC/FINI packets.
* The former two fix the problem that connections wouldn't be closed
correctly and could even be reused when trying to connect again (as
was reproducible with svnserve + svn).
* Some style cleanup in CPEndpoint.h.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23984 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Implemented automatic syscall restarts:
- A syscall can indicate that it has been interrupted and can be
restarted by setting a respective bit in thread::flags. It can
store parameters it wants to be preserved for the restart in
thread::syscall_restart::parameters. Another thread::flags bit
indicates whether it has been restarted.
- handle_signals() clears the restart flag, if the handled signal
has a handler function installed and SA_RESTART is not set. Another
thread flag (THREAD_FLAGS_DONT_RESTART_SYSCALL) can prevent syscalls
from being restarted, even if they could be (not used yet, but we
might want to use it in resume_thread(), so that we stay
behaviorally compatible with BeOS).
- The architecture specific syscall handler restarts the syscall, if
the restart flag is set. Implemented for x86 only.
- Added some support functions in the private <syscall_restart.h> to
simplify the syscall restart code in the syscalls.
- Adjusted all syscalls that can potentially be restarted accordingly.
- _user_ioctl() sets new thread flag THREAD_FLAGS_IOCTL_SYSCALL while
calling the underlying FS's/driver's hook, so that syscall restarts
can also be supported there.
* thread_at_kernel_exit() invokes handle_signals() in a loop now, as
long as the latter indicates that the thread shall be suspended, so
that after waking up signals received in the meantime will be handled
before the thread returns to userland. Adjusted handle_signals()
accordingly -- when encountering a suspending signal we don't check
for further signals.
* Fixed sigsuspend(): Suspending the thread and rescheduling doesn't
result in the correct behavior. Instead we employ a temporary
condition variable and interruptably wait on it. The POSIX test
suite test passes, now.
* Made the switch_sem[_etc]() behavior on interruption consistent.
Depending on when the signal arrived (before the call or when already
waiting) the first semaphore would or wouldn't be released. Now we
consistently release it.
* Refactored _user_{read,write}[v]() syscalls. Use a common function for
either pair. The iovec version doesn't fail anymore, if anything could
be read/written at all. It also checks whether a complete vector
could be read/written, so that we won't skip data, if the underlying
FS/driver couldn't read/write more ATM.
* Some refactoring in the x86 syscall handler: The int 99 and sysenter
handlers use a common subroutine to avoid code duplication.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23983 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Tracing of allocations, reallocations and frees
* Leak checking infrastructure to dump allocations
The leak checking code records the team and thread id when an allocation is
made as well as stores the originally requested size. It also adds the
"allocations" debugger command that can dump all current allocations (usually
a huge list) or filter by either a team or thread id. This way it's easily
possible to find leftover allocations of no more active teams/threads.
Combined with the tracing support one might be able to track down the time and
reason of an allocation and possibly find the corresponding leak if it is one.
Note that kernel heap leak checking has to be enabled manually by setting the
KERNEL_HEAP_LEAK_CHECK define to 1.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23953 a95241bf-73f2-0310-859d-f6bbb57e9c96
and pages are now kept in lists as well. This allows to return free pages once
a bin does not need them anymore. Partially filled pages are kept in a sorted
linked list so that allocation will always happen on the fullest page - this
favours having full pages and makes it more likely lightly used pages will get
completely empty so they can be returned. Generally this now goes more in the
direction of a slab allocator.
The allocation logic has been extracted, so a heap is now simply attachable to
a region of memory. This allows for multiple heaps and for dynamic growing. In
case the allocator runs out of free pages, an asynchronous growing thread is
notified to create a new area and attach a new heap to it.
By default the kernel heap is now set to 16MB and grows by 8MB each time all
heaps run full.
This should solve quite a few issues, like certain bins just claiming all pages
so that even if there is free space nothing can be allocated. Also it obviously
does aways with filling the heap page by page until it overgrows.
I think this is now a well performing and scalable allocator we can live with
for quite some time. It is well tested under emulation and real hardware and
performs as expected. If problems come up there is an extensive sanity checker
that can be enabled by PARANOID_VALIDATION that covers most aspects of the
allocator. For normal operation this is not necessary though and is therefore
disabled by default.

defined flag: NET_PROTOCOL_ATOMIC_MESSAGES.
* socket_send() now honours NET_PROTOCOL_ATOMIC_MESSAGES and returns either
EMSGSIZE if the data to be send is larger than net_socket::send::buffer_size,
or divides the data in appropriately sized chunks.
* This fixes sending >=64K over a TCP socket at once (TCP would just have
returned an error in that case).
* TCP now overrides the default send buffer size (to 32768 for now).

* Added "traced" option --difftime. Instead of the absolute system time
it prints the difference time to the previously printed entry.

(must also compare to BSD; I've looked at their sources, but I might have
missed something).
* Added sys/file.h and the flock() system call.
* common_fcntl() could forget to put back the file descriptor on some error
conditions (I guess we should introduce and use a DescriptorGetter class).
* Cleaned up fcntl.h, moved the BSD extensions S_IREAD and S_IWRITE to
sys/stat.h where they belong, and added the missing S_IEXEC to them.
* Added some more comments.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23836 a95241bf-73f2-0310-859d-f6bbb57e9c96
* added optional tracing for the main operations
* fixed bad pointer arithmetic when reallocating/moving the object's data
* it was impossible to remove the very first space via _RemoveSpaces()

* While this is not a really good idea for a lock with supposedly little
contention, but it'll fix bug #1731. I haven't tested it yet, but will
do so in a minute :-)
* I will need to rework the slab anyway so that it's possible to use it
as a replacement for our heap, and then I'll switch back to a benaphore
again.

we now always only use the primary ring buffer.
* Removed secondary ring buffer allocation and member fields.
* Increased size of the primary ring buffer to 65536 bytes.
* The bytes per row register is computed differently for 9xx chips.
* On G33, the overlay does not need a physical address anymore, so we
don't pass B_APERTURE_NEED_PHYSICAL to the allocation anymore for that
device.
* intel_free_memory() accidently added the aperture base to the allocation
and would therefore never free any memory.
* INTEL_RING_BUFFER_SIZE_MASK was shifted one bit to the right, didn't
cause any harm with our buffer sizes, yet, though.
* With these changes, the driver runs stable on a G33 chipset (I have not
yet tested the hardware cursor, though, it might need some work, too).
The only known issue left is that overlay flickers a bit if its buffer
is partially backed up by reserved and allocated memory.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23798 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Removed "physical" parameter of GART's bind_aperture() - I don't think this
be of use to anyone.
* Fixed binding/unbinding pages in the Intel GART driver; I accidently shifted
the page offset twice.
* Actually forgot handling of allocated memory in Aperture::BindMemory().
* Minor cleanup.

* The kernel now opens up to 8 debugger modules (and puts them into an array;
maybe we'll want to switch to a doubly linked list when there is the need).
* Implemented an example debugger module that prints a stack trace of the
current thread when the kernel debugger is entered (not included in the
image).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23794 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Now uses the AGP GART module for memory management. This greatly simplifies
the memory handling, and memory is now actually allocated on demand,
instead of a fixed size (stolen memory is not freed, though).
* The Intel GART module should now also work with older chipsets.
* No longer remove the GTT size from the stolen memory; this appears to have
been a mistake in the X driver. Not sure about the BIOS popup yet.
* The AGP module (in combination with the Intel GART module) is now mandatory
to use the Intel driver.
* Removed now superfluous settings (like memory size). Only enabling/disabling
the hardware cursor is still supported.

* It now also serves as a generic GART manager and accepts bus modules as well
as custom modules of graphics drivers if they want to (could be used for the
Radeon PCI GART stuff, for example).
* Implemented GART support module for Intel i965 and G33 chipsets (the other
Intel chips will come later).
* Renamed agp bus manager to agp_gart to reflect its new functionality (even
though the AGP functionality is already outdated (due to PCIe), the GART
stuff remains current).
* Adapted existing users of the AGP bus manager to the API changes.
* Not very well tested yet...

worked correctly when you specified more memory than the amount of stolen

* Implementing maintaining resources for emulating overlay using the 3D engine

b) does not work yet.

For commands with this flag set, the parser won't parse the
arguments provided (it will only check for matching parentheses and
brackets), but will pass the unparsed argument list string to the
command instead.
* Set the new flag for the "expr" command, so one doesn't have to quote
the expression to evaluate anymore (or put it in parentheses).
* Fixed tokenizing of quoted and unquoted strings in expression mode.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23697 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Removed the public hash_grow() function again (at least for now, it's only
private).
* Removed the newSize argument from hash_grow(); it will compute the new size
automatically.
* The block cache is now using hash_insert_grow() instead of hash_insert()
which should make hash lookups much faster with some 10 thousand blocks,
also increased the initial table size from 32 to 1024...

write code aligned to what one has written in the comment (or the
other way around).
* Made trace_entry structure doubly linked, by introducing a
previous_size member. By using bit fields, shrinking the flags field
to 4 bits, and not saving the lower two bits of size and previous_size
(which are always 0 due to alignment), the structure remains 4 byte
sized and can still address the same entry size.
* kBufferSize is no longer one less than it could be.
* "traced" command:
- Use static variable for the iteration state rather then cluttering
the temporary debug variable name space.
- The <count> parameter can now be negative, in which case the entries
before (and including) <start> are printed.
- Added a new optional parameter, specifying the maximal number of
entries to be filtered. Filtered iteration is beautifully
comfortable now.

blocks into the new transaction, but it would set that transaction on all
blocks of the old transaction, too. Also, it did not correctly update the
num_blocks/sub_num_blocks fields of the old transaction. Even worse, it did
return B_OK instead of the ID of the new transaction...
* get_writable_cached_block() did not correctly maintain the number of blocks
in the sub transaction.
* write_cached_block() did not free the original_data of a block when it wrote
it back as part of a previous transaction.
* Changed "cookie" for cache_next_block_in_transaction() to "long", so it will
be 64 bits when needed.
* Improved the API for detaching sub transactions: you can now get the blocks
of only the main (parent) transaction as well, added new
cache_block_in_main_transaction() function.
* BFS now flushes the log when there is no space left for the current
transaction.
* _WriteTransactionToLog() allocated a "vecs" array, but never freed it.
* _WriteTransactionToLog() now also supports detaching the current sub
transaction if the whole thing is getting too large (it will now also panic
if that doesn't work out).
* Removed a useless optimization: making the blocks available in the cache
isn't really needed, as all blocks in a transaction are locked into the
cache, anyway.
* Implemented Transaction::WriteBlocks().
* Minor cleanup, removed some dead code, fixed warnings in the fs_shell's
block_cache when compiled with debug output on.

temporary variable is overwritten, if there's no free slot for a new

* Removed the special handling for the command result variable ("_"). It
just works like any other temporary variable, now.
* Individual temporary variables can be removed (e.g. using the "unset"
command).
* Added unset_all_debug_variables() and "unset_all" command to unset
all persistent and temporary variables.

that is a little more powerful than BeOS'. It features:
- Persistent and temporary uint64 variables. The former kind is set
only by the user. The latter (those prefixed "_") can be set
automatically by commands, thus e.g. making it easier to access
members of a dumped structure. They are unset when the next command
is invoked. The special temporary variable "_" is defined as a
command's return value.
- Expressions can contain nested command invocations using brackets
("[ ... ]").
- Command lines are parsed by the expression parser, too. They can
contain command invocations (in brackets) and expressions (in
parentheses).
* Added debugger commands:
- expr: Evaluates the given expression and prints the result.
- unset: Undefines a variable.
- vars: Prints the values of all defined variables.
* Moved debugger command code into its own source file.

transaction ends or has been aborted.
* BFS now listens for transactions when it created an inode to see if
the transaction will be aborted without freeing the inode (in which
case it will panic for now).
* Started implementing tracing support, but it's not working yet.
* Minor cleanup.

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.

* Added function to allocate space in the buffer.
* Dump() now fills a buffer instead of printing its data directly.
* This allows the new "#pattern" argument of the "traced" command to
work. When you're using that, the index of the trace entry is printed
out, too, so that you can then get a full dump around the hits.
* Added an AddDump() method to the AbstractTraceEntry class so that
there is no need to call the inherited function anymore.
* Minor cleanup.

will not accept if the allocator returns NULL and crashes instead
(ie. not compiling in tracing would have crashed if some module tried
to use it).
* Added total entries count to the KDL command output.
* Fixed computing the start index of the KDL command.

* Implemented an optional tracing layer that can be used in the kernel.
Nice to use if you don't have serial output or need something that doesn't
slow down the system as much.

* Move most of MIME database support out of libbe and into registrar
* Use the (async) MessageDeliverer instead of a synchronous SendMessage in _SendMonitorUpdate
This fixes a deadlock when the message port of a MIME database watching
application gets full as documented in bug #1311.

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).

resized but still had dirty pages to be written back,
vm_cache_resize() (which is called with the inode lock being held)
deadlocked with the page writer.
* Now, I reintroduced busy_writing: it'll be set by everything that
writes back pages (vm_page_write_modified(), and the page writer),
and will be checked for in vm_cache_resize() - other functions are not
affected for now, AFAICT.
* vm_cache_resize() will clear that flag, and the writer will check it
again after it wrote back the page (which will fail when it's outside
the file bounds), and if it's cleared, it will get rid of the page
(if the file has been resized again in the mean time, writing it will
succeed then, and we'll keep the page around).

appear: when freeing a modified page, it wouldn't have a cache
anymore, but set_page_state_nolock() depended on it.
* To work around this, I added a vm_page_free() function, which the
caches that free modified pages have to call (but others may, too).
It will correctly maintain the sModifiedTemporaryPages counter in case
the cache has already been removed.

Moved GetMouse() calls near the check for exit conditions.
Reorganized a bit the code, and hopefully simplified it in some places.

* Implemented mapping the GTT area for i9xx chips other than the i965. This should also fix the
driver working with these chips at all.
* The memory used by the driver now take the GTT area into account - before the GTT could be
overwritten theoretically...
* Added fix for some i965 quirks from the X driver.
* Added some overlay definitions for the i965.
* Started support for G33 overlay (not complete yet).

Replaced IDE_ADAPTER_IS_PRIMARY by IDE_ADAPTER_CHANNEL_INDEX to support more than 2 bus master channels,
and made ide_adapter aware of 3rd and 4th channel when calculating bus master dma address.
Fixed bus master DMA support in legacy_sata driver for tertiary and quaternary channel, channel 3 and 4
were using the DMA engine of primary and secondary channels (that might have destroyed your data).
Use PCI_address_io_mask instead of ~PCI_address_space (no functional change).

- in order to set cursor position SVGA_CURSOR_ON_SHOW has to be written to register SVGA_REG_CURSOR_ON.
- do not use alpha cursor because it does not support inverting of source pixels.
- Fixed wrong usage of if-statement inside switch-statement
- Sync at end of SCREEN_TO_SCREEN_BLIT so that app_server does not write to frame buffer while accelerated operation is still running.

* Implemented MakeSpace() (not yet tested).
* Changed intel_wait_engine_idle() to spin() between reads and to timeout
after 1 second of waiting (could probably be done way earlier).

* ACPI is evaluated first as it also handles things like multi core or hyper threading setups
* Removed other (disabled) hyper threading code per the notes in the corresponding ToDo
* Limit the detected CPU count to 2 for now as I wasn't able to get it working in either emulation nor real hardware with more than 2 CPUs
* Added a reserved byte to the mp_config_table struct, it worked only by luck as the compiler did padding there to get to the same size
I can now boot my Core 2 Quad with two out of four processors active :-)

* Therefore, I've added an I/O control that let's it update the boot block
part of this block, so that makebootable can use it on a mounted volume
(this will probably be moved into a disk system API later).
* Added user_memcpy() to the fs_shell.
* Minor cleanup.
