overwritten.

code:
- The vec array to contain the block list and the index block was one entry
to small.
- But that didn't really matter, as RunArrays/run_array was broken and never
put anything into the log; we only ever wrote index headers. BFS would
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.
* run_array now adopt the sorting stuff from the sorted_array. Blocks in the
log are now always sorted.
* Added TODO item to sorted_array as it's not endian safe (will only work
correctly when BFS is used in the native endian).
* Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23638 a95241bf-73f2-0310-859d-f6bbb57e9c96
we use a uint16 size internally (and that has to include the length of
the trace_entry structure, too.
* We now track how many entries have been written to the log during the
runtime.

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.

before releasing our cache reference. Otherwise removing a vnode (triggered
by releasing the cache in our thread) could need pages we still own.
* Put the caches and pages into a union to save stack space; they are not
needed at the same time.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23580 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Removed ID 0x0141 for the FX 6600 as well until it's fixed, see ticket #1530
for details.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23579 a95241bf-73f2-0310-859d-f6bbb57e9c96
(so we can't allocate more physical pages than virtual address space
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.

paging support to KDL (but not the on-screen debug output for now).
* Defaults to "on", use the new "paging" KDL command to turn it off (or on
again).
* When pressing 'q' while it is waiting for a key, it will now eat the rest
of the commands output (helpful for slow screen output of a large data set).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23566 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Fixed the usage text of the "help" KDL command.
* Made the "ambiguous command" warning shorter, so that it will still fit in
the exception buffer.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23565 a95241bf-73f2-0310-859d-f6bbb57e9c96
* As a temporary work-around for the current slab allocator's area usage,
I added the CACHE_LARGE_SLAB flag, which will force the allocator to
use larger areas.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23563 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Use parse_expression() where appropriate.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23556 a95241bf-73f2-0310-859d-f6bbb57e9c96

after the first command).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23555 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Made the block_cache KDL command dump a bit more useful info (number of
referenced and dirty blocks).
* Minor cleanup.

* with 1 GB or more, the semaphore limit is now 131072 instead of 65536.
* double the heap when there is 1 GB or more (64 MB).
* the low memory handler now also watches semaphore usage; in the end,
we need a low resource handler, not a low memory handler.
* create_sem_etc() no longer calls vfs_free_unused_vnodes() directly as
this could actually deadlock (at least because the address space is a
R/W lock, not a recursive lock).

compute the bit offsets correctly if the last block of the whole
bitmap was only a partial block.
* Added new bfs_allocator KDL command.
* Renamed the KDL command bfsinode to bfs_inode.
* Added "--help" argument to bfs_inode and bfs KDL commands.
* Added more tracing in the block allocator.
* Turned on the ASSERT() macro in non-debug builds.
* Minor cleanup.

* alloc_tracing_buffer() no longer allocates anything when you ask for
a zero byte buffer.
* Fixed warning.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23533 a95241bf-73f2-0310-859d-f6bbb57e9c96
* improved the "block_cache" KDL command: it can now also dump blocks,
added support for the "--help" argument.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23532 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added missing license.

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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23492 a95241bf-73f2-0310-859d-f6bbb57e9c96
though there was nothing to do (if 'diff' was larger than 'needed').
* Improved KDL command output.
* Added debug output to the allocation functions.
* Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23491 a95241bf-73f2-0310-859d-f6bbb57e9c96
* 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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23479 a95241bf-73f2-0310-859d-f6bbb57e9c96
DEBUG macro; they are now added only if BFS_DEBUGGER_COMMANDS is
defined (which is now done by default in the Jamfile).
* Added "bfs" KDL command which dumps volume information and the super
block.
* Made use of the new tracing API to trace block and inode actions
(and the new AbstractTraceEntry class I forgot to mention in the last
commit). Is compiled in only when BFS_TRACING is enabled (defaults to
off in the standard builds).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23464 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23460 a95241bf-73f2-0310-859d-f6bbb57e9c96
* 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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23447 a95241bf-73f2-0310-859d-f6bbb57e9c96
* vfs_disconnect_vnode() did not put away its vnode reference.
* disconnect_mount_or_vnode_fds() did always throw the current working
directory of all apps on the same mount away, even if only a specific
vnode should have been disconnected.

* Changed syscall color to blue (signals are red).
* Added thread number to the signal output.
* -g turns off signal tracing now.

* If two intersecting windows didn't change their position but their
order, the dirty region wouldn't contain the region that would need
to be updated because of that order change. This fixes bug #827.
* When a hidden window was on the new workspace (but not on the old one),
its region would be included in the dirty region, but shouldn't have
been. This caused the app_server to update a larger region than
necessary.

couldn't be read from a file, Tracker would try 10 times with a 10 ms
timeout - but only if the creation time equals the modification time!
That was obviously supposed to be a check if the file was recent...
Now that computers are faster (even when running Haiku), it may
actually take less than one second to copy a file, so most files on
the Haiku image satisfied this thoughtful and future-proof check.
(And no, even the original BFS does not automatically increase the
modified time on close.)
* Now, mmlr came up with a better check: we just check the file's
creation time against the current time to see if it's a recent file.
That should work a bit more reliable :-)
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23376 a95241bf-73f2-0310-859d-f6bbb57e9c96
This fixes the bug described by Stefano in r23343.
* Therefore, I enabled cached menu windows again.

* Started a "View As" feature which will allow you to use the type
editor for the file itself - not yet enabled (or working).

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.

a function in the stack trace (only works reliably when a stack frame
is exists, and you'll have to know the number of arguments).
* Refactored the functions a bit and extracted setup_for_thread() out
of stack_trace() to be used by show_call() as well.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23316 a95241bf-73f2-0310-859d-f6bbb57e9c96

potential data corruption. This fixes bug #1388.
* get_node_at_offset() would return a node too early in the list if the offset
fell on a node boundary - didn't cause any actual harm, though.
* append_size(): renamed variable tailSpace to previousTailSpace to make
it clearer.
* Improved debug output for duplicate_buffer() and clone_buffer().
* Debug output is now prepended by the thread ID.

set when the first chunk of the file could be read in directly, causing it
to read data to a wrong place in the buffer.
* Reading in the first chunk directly would have also only worked if vecIndex
and vecOffset was 0 when calling the function.
* Applied the fs_shell changes in file_map to the kernel version as well (the
constructor already worked correctly, though).

* Also fixed file_map_translate() which was hiding this problem.

with its destructor when the socket is deleted. This effectively stopped all
network timers from working. This will not only fix bug #1693, but also many
other networking problems I've seen so far.

parentheses).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23251 a95241bf-73f2-0310-859d-f6bbb57e9c96
* 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).

a bit more work on the compatibility layer.
* Added nVidia nForce MCP driver (nfe) from FreeBSD. Compiles and might even
work - please test. It would also be nice to know if your PHY is detected
correctly (see syslog output).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23124 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Changed intel_wait_engine_idle() to spin() between reads and to timeout
after 1 second of waiting (could probably be done way earlier).

the 3com driver)
* We need to acknowledge the interrupt in the handler, because else, the interrupt continues
to fire after the PIC interrupt is acknowledged by the kernel.
* It also helps a lot to turn off the interrupts on the device while xl_intr() is handling
the interrupt.
* When the slow handler is running, we now set the new "handling" field in the internal
interrupt handler which will not invoke the scheduler then (but only signals a handled
interrupt).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23085 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Also, loop as long as new interrupts are coming in.
* This fixes the high CPU usage and low throughput of the 3com driver; it now works just fine;
dunno why it worked for me that well last time.

* 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

* Minor cleanup.

call this function if you don't know if a device has a direct reference to one of
its children. Since we want to be able to delete the root without having any knowledge
about its children, we now detach everything first, and then delete the entries.
This fixes a possible crashing bug when a preloaded driver (used for network boot)
tried to acquire its resources again at a later point.
* device_detach() and device_attach() now check if the device has an attach or detach
method at all.
