was a race condition when more than one CPU would enter the debugger at the
same time (or rather before one CPU could stop all the others). We now use the
inDebugger variable to tell if someone is already in the debugger and then
only process inter CPU messages and retry entering the debugger.
Since sending the synchronous broadcast most of the time hung over here with
SMP enabled I removed the synchronous flag and added a simple spin to give the
other CPUs a chance to process the halt request. Added comments that explain
the reasons and a ToDo to revert to synchronous delivery once we fixed the
problem. The kernel debugger is now usable on my quad core.

A thread that just missed a semaphore and put itself into the sems notify
queue could be enqueued into the run queue by release_sem_etc() of another
CPU before the CPU running the thread had a chance to reschedule it. Therefore
there is a timeframe where a thread can be running on one CPU and already be
in the run queue again. In this case no other CPU may schedule this thread
because then it would overwrite the threads' CPU pointer which kills the rest
of the scheduler logic, smp_get_current_cpu() and everything that depends on
that (like the kernel debugger). The more CPUs you have the easier this could
happen, up to the point where it was always triggered during boot on my quad
core system. The system would freeze and you could not enter the kernel
debugger, because two CPUs thought they were the same and disabled each other
through SMP communication. This makes booting my system stable and might fix
the occasional hang on boot for other SMP systems with only 2 CPUs/cores.
I've put a ToDo comment that details this above the workaround. Maybe we
should fix this in another way. Reviews, comments and suggestions welcome ;-)

For commands with this flag set, the parser won't parse the

views don't have a valid screen clipping yet. If then later we want
to invalidate the clipping of an entire hierarchie, the traversal stops
before reaching some of the child views, because the assumption was that
for any views with invalid screen clipping, their child views have invalid
screen clipping as well. Though this might cost a little performance, we
always invalidate the screen clipping of all child views, ignoring the
flag of the current view. Fixes ticket #1198 (garbled screen clipping of

vm_cache_write_modified() here anymore since quite some time, it actually
doesn't make any sense to call the file system's "fsync" method here.
This should make syncing all file systems much faster when many vnodes are

it needs to in its "sync" method.
* Added a TODO item on how to improve sync speed further, if necessary.

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.

disabled in most cases.
* Wrapping in make_space() was broken. When wrapping the second time or
later, sFirstEntry would already be greater than sAfterLastEntry and
resetting sAfterLastEntry to the beginning of the buffer would
erroneously "free" all entries between the buffer start and the
original sAfterLastEntry. If the tracing buffer was small enough,
the odds were that a not yet fully initialized entry would already
be re-allocated, causing all kinds of weird behavior.
* When an entry that is not yet fully initialized needs to be
freed, we let the allocation causing the freeing fail. We can't wait
for the entry, since we've interrupts disabled and since the entry
initialization might even try to allocate more (buffer) entries.
* make_space() is now safe to be called in any situation, and
allocate_entry() will do that, which simplifies things there and
avoids a few duplicate checks.
* Moved maximum allocation size check from alloc_tracing_buffer() to
allocate_entry(). Just in case... :-)

totally screw up the disk when trying to replay the log (even though the
replay code itself was and is working fine).
- If a log entry ended at the end of the log area, BFS could overwrite the
first block after the log with the next entry.

* Refactored everything to C++ with the different devices as subclasses
* Added proper ACM detection with parsing of the ACM descriptors
* Added device transfer error handling and fixed some concurency issues
* Big cleanup to conform to our style guide
This should make at least ACM stable to use. Commiting this over my K850i with
ACM compliant USB modem and UMTS data connection. Note that support for all
other device classes (Prolific, FTDI and KLSI) is untested but should work the
same as before. Note also that since we currently lack a TTY module this will
only build/work for R5 or Dano with the proper TTY headers.

its parent while still holding the team spinlock. We were racing with
wait_for_child(), since after the child invoked
team_set_job_control_state(), the parent thread could continue as soon
as the team spinlock was released. The SIGCHLD could thus arrive way
later and interrupt another syscall. This could be reproduced with the
compile_bench.sh script from time to time: When interrupted while
waiting for the next subprocess, the gcc frontend would delete a still
needed temporary file.
The whole thing is actually only a problem, because we don't support
automatic syscall restarts yet.

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.

- Was printing one more entry than asked to.
- Fixed broken index handling. They were starting at 0, but the last
one was sEntries nevertheless. We consistently let them start at 1,
now. 0 can be passed as special index, causing the last entries to
be printed.
- Added options "backward"/"forward" which will print the entries
preceding respectively succeeding the ones printed on the previous
invocation. The command is continuable in this case, i.e. simply
pressing RET afterwards will reinvoke the command, allowing for
comfortable scrolling through a long list of entries.
- Added detailed usage message.

* With post syscall debugging enabled, the x86 syscall handling didn't
remove all parameters from the stack after calling the respective user
debugger hook. Should have been harmless though, since the following
code didn't rely on the stack being in order.
* Added syscall pre/post (kernel) tracing functions
trace_{pre,post}_syscall(). They are generic, but need to be invoked
by the architecture specific syscall code. Currently only done for
x86.

of the descriptor from its physical address returned by the controller.
NOTE: As stated in the commented code, when the controller has finished processing
some descriptors, it returns the first element physical address of an heterogeneous list
(general + isochronous) and there is not way to tell the descriptor type.
This solution, which implementes two hash tables (one for generic descriptors and
one for isochronous) is the one adopted from *BSD.

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

remove_debug_variable() to unset_debug_variable().

anymore, but so what?).
* Used the new CACHE_LARGE_SLAB flag as a temporary work-around; else
the slab would easily create several thousands of areas, which our
area code (and kernel heap) can't really handle that well (gets
awfully slow).
* Block caches with the same size could share the same slab, but we
don't do that yet.

now allocated on the stack and placed in the "cinfo->err" structure. This

that only loads bitmaps and is supposed to return a status_t error from
the Translate() function, especially for people using this in mission
critical applications.
The requirements on the error handler that is
to be installed for the jpeg library are not to return to the calling
function for critical errors. C++ exceptions seem like the
natural solution to the problem, but unfortunately, they simply don't
seem to work, possibly because we are inside an add-on. Ingo had the idea
to use setjmp() and longjmp() to go directly from the error handler back
to the top level code and this works. I have implemented this from what
I understand from reading the opengroup spec, but the compiler currently
issues a warning. Feel free to fix. The desired effects are achieved though,
the translator recovers correctly from broken jpg files now.
Also, I don't know if the translator should somehow "uninstall" the
breakpoint. Again, feel free to fix or tell me.
