space left for the new log entry, it did call cache_sync_transaction(), and
then just assumed the space would be ready. But since the transaction could
have been written before that call by the block writer, and since the
_TransactionWritten() hook is now called asynchronously,
cache_sync_transaction() actually has to flush all pending TRANSACTION_WRITTEN
notifications before returning to the caller.
* To implement this, block_cache now publishs a condition variable, and
wait_for_notifications() adds a fake notification that signals that one.
Since the notifications are handled in FIFO order, this guarantees that
the previous TRANSACTION_WRITTEN hook is done.
* notify_transaction_listeners() could accidently delete notifications that
still had pending signals. Now, it will defer the deletion to the notification
thread instead in that case. This should fix bug #2008.

wrote the super block, so there was a race condition with what
_WriteTransactionToLog() assumed was already written there (if it managed to
write the log entry before the super block was written by
_TransactionWritten(), and a reboot happened just then, the log start could
point to an invalid log entry). Not very likely, but it could happen.

Haiku code, they work around buggy BeOS code not present on Haiku.
* If this code turns out to be problematic under Haiku (Bruno, did your changes
make any difference at all?), then please fix the problems in the Storage
Kit, don't enable work-arounds for BeOS.
* Simplified the macro check as suggested by Ingo.

if these changes are correct byt they seem to make sense. Ingo?
- Haiku uses the same code that BeOS/Dano/Zeta uses for mime related stuff
during the build process. Added checking for HAIKU_HOST_PLATFORM_HAIKU where
relevant.

* Added {Create|Delete}Device() analogous to {Create|Delete}FileDevice
* Added a small DeviceWatcher class that reacts to entry creation/removal
* Implemented a way to start/stop node monitoring
* Start watching for devices after the boot volume has been mounted and the
the second initial scan was run
The disk device manager now creates and scans a device when a "raw" node is
published and deletes the device on removal. This makes hot-plugging of disk
devices (for example memory sticks using usb_disk) work. Their partitions will
be scanned and published so they can be mounted. Somehow the removal of the
partitions does not yet work however, any insights are welcome.

the icons are centered.
* The boot loader and kernel now use the placement info that
generate_boot_screen now generates.
* Made the code that draws the images handle the case where any of the images
is larger than the frame buffer.
* All drawing functions need to know the image width (analogous for bytes per
row).

PackageInstaller, ZipOMatic, and the Expander now all have the same

called without having the cache's lock held.
* The only downside to this approach is that ending a transaction now needs
additional memory, and might therefore fail - that could be fixed by
allocating that memory upfront with the start of the new transaction,
though.
* Therefore, I reverted the cache lock to a benaphore, as the recursive
lock is no longer needed.
* The block writer thread is now a block writer and notifier thread: it will
wait for up to 2 seconds on the sEventSemaphore, and if nothing comes in,
it will continue with its previously sole job.

* The count/info view in Tracker truncates the text in a better way when
it does not fit, and also used the space of the barber pool when it isn't
displayed.

* Introduced a new publish_node() which then actually publishs the node,
similar to the VFS's new_vnode(), and publish_vnode() semantics.

check in notify_transaction_listeners() didn't hold, although the
cache_hooks were deleted anyway. I've introduced a listener_change
counter to detect changes to the listener list while iterating, since
any change makes the iteration unsafe. Should fix bug #2008 for real.
Nevertheless I thing the transaction listener concept needs revision.

allows event listeners to add new listeners inside a node monitoring event
(i.e. if one wants to add a listener for the entry that has just been created
and triggered the current notification).

Instead return the directory vnode, so the calling function can insert it after
all vnode initialization is done. Otherwise entry created notifications are
sent upon inserting the node into the directory for vnodes that are not yet
fully initialized (i.e. they have no type or the device hooks are not yet set).
That would cause for example ioctls to fail when someone would react to a
notification of a newly created device.

functions by ones reading /etc/{group,passwd}.
* Added quasi-standard getpwent_r() and getgrent_r().
* Added _SC_GETGR_R_SIZE_MAX and _SC_GETPW_R_SIZE_MAX sysconf()
constants.
* Moved initgroups() and getgrouplist() definition to grp.cpp. They use
the same backend as the <grp.h> functions.
* Set the permissions of files created by the build system to what they
should be on the image (executables: 755, others: 644). Otherwise only
root could do anything under Haiku.
* Added build system variables HAIKU_ROOT_USER_NAME and
HAIKU_ROOT_USER_REAL_NAME to customize name and real name of Haiku's
root user.
* Added build system rules AddUserToHaikuImage and AddGroupToHaikuImage
for adding additional users and groups (by default only root user and
group and a "users" group are created).
* Adjusted BIND port and coreutils config.h files according to what
features have become available.
* Fixed HAIKU_DOCUMENTATION_OBJECT_DIR definition. Untested, but it used
a wrong variable name before.

overcommitting stores:
- has_precommitted was incorrectly set to true in the constructor
- when a precommitted page was committed, vm_store::committed_size
was still changed.
- unreserving memory did not update vm_store::committed_size.
- when precommitted pages were committed, their page count instead of their
size was reserved.
* All this lead to bug #1970 which should be fixed now.
* Cleanup of vm_cache.cpp, no functional change.

current cursor without locking, and did not add a reference while
using the cursor. I have tried to solve both problems by introducing
a simple ServerCursorReference class, which makes sure that the
reference count is properly maintained. There are only two places
where this code was even used, from within ServerApp and when taking
screenshots. Axel, you mentioned in #837 that the code is unsafe, is
this what you meant? This hopefully fixes#837, but it is very hard
to reproduce in the first place, I will close the ticket, but it should
just be reopened if ever encountered again.
