been mounted, before anyone could try to load any modules from it.
Also pass it a flag whether the boot volume is where the boot loader
pre-loaded the modules from.
* module_init_post_boot_device() changes the pre-loaded module image
paths to normalized boot volume paths, now. Got rid of the code in
register_preloaded_module_image() which tried something like this.
* Changed module image ref counting. A referenced module has single
reference to its image, which is released when the module becomes
unreferenced.
* get_module() for a reference module will not try to re-get and re-set
the module's image anymore. That could lead to a similar module (from
different paths) being loaded at the same time. A module from a new
file can only be loaded when the old one has been put completely.
* Simplified B_KEEP_ALIVE module handling a bit. When the module is
initialized, we add another reference, which we'll never free. Thus
the module remains loaded without special handling. Removed
module_image::keep_loaded. A B_KEEP_ALIVE module remains referenced
and thus its image remains referenced, too.
* Removed module::file, a cached path to the module's image. An
optimization that wouldn't work with multiple root directories for
modules (/boot/beos/..., /boot/common/...) or when module files were
moved. get_module() does now always search the image file, when the
module is still unreferenced. This should be a bit slower than before,
but I didn't notice any difference in VMware at least. If it turns out
to be a problem we could introduce a more intelligent cache that stays
up to date by using node monitoring.

function (normalize_path()), now. There was some code duplication
before.
* Added "bool traverseLink" parameter to vfs_normalize_path(). When
true and the leaf component is a symlink, it will be resolved.
* KPath:
- Added similar leaf link traversal parameter to SetTo() and
SetPath().
- Added Normalize().
- Added DetachBuffer(), which returns the object's current buffer and
unsets itself.

elf_add_memory_image_symbol(). The former creates and registers a new
image that has not been loaded from a file. The latter adds a symbol to
its symbol table. This is mainly a debug feature, allowing to name code
or data in memory regions that aren't associated with loaded ELF
objects.

* Extended the profiling API by an option to record a variable number of
samples per tick. The stack depth is used as a maximum.
* Added new option "-f" to the "profile" tool. When specified it
increments the hit counts of all symbols in the full available caller
stack. I.e. the resulting hit counts will approximate the total time
spent in each function or any function directly or indirectly called
by it. Thus "_start" and "main" will usually get 100% and leaf
functions only what time has actually been spent in them.

always also removed all elements in the same bucket preceding the one
to be removed. Also got rid of the useless "for" loop.

* The class calculates a minimum width now, which is based on the line height,
this may also fix the bug with the small text inputs in the Pe Find window.
* Added TODOs about implementing GetHeightForWidth(), which may be a good idea
when a BTextView is used as non-editable informative text in an interface,
and one wants to make sure that the entire text is shown.
* Replaced the call to _Refresh() in Draw(), which recalculates all the line
breaks for no reason with _DrawLines() again. The TODO mentioned that text
will be drawn without drawing the background first, but maybe this is a
relict from times where Draw() was invoked directly? At least I cannot see
any negative consequences, and this should be much more efficient.
(Other than that, this patch should hopefully have no potential negative
side effects...<crosses fingers>)

* Adjusted used files systems accordingly.
* BFS::Stream::GetName() was broken. It accessed the small data region
which wasn't loaded, since BFS::Stream derived from bfs_inode, which
is a variably-sized structure with the small data region at the end.
Changed that to a ref-counted, shared member instead.
* Implemented RootFileSystem::GetName().
* Added Directory::GetPath() to get a full path of the directory or an
entry.

buffer during a timer event that interrupted a kernel function: We do
now flush the buffer as soon as it is 70% full, *if* we didn't interrupt
a kernel function. When the buffer runs full and we still haven't hit a
user function, we drop the tick. The number of dropped ticks is recorded
and sent to the debugger with the next update message.
Reverted the previous partial solution (the temporary disabling of
profiling while in debugger support code).

is created or deleted (or exec*() has been invoked). The counter is
sent with several debugger messages.
* Track the image event counter that is used when samples are added to
the profiling buffer. If the current team counter differs, we flush
the buffer first (sending an update message to the debugger), so that
the debugger has a chance to match the addresses to the correct images.
* Disable profiling for a thread while it runs in the debugger support
code. This fixes potential deadlocks which could occur when a
profiling timer event occurred that would require the buffer to be
flushed while the thread was just sending something to the debugger or
waiting for a command. As it turns out, this is not sufficient either,
since we should never try to flush the buffer when the timer event
occurred in the kernel, since the thread might hold a lock that the
debugger thread could try to acquire. Will implement a more general
solution later.

BTextView classes:
* Declared the directly used BTextView helper classes as private BTextView
classes and changed all affected files.
* Realized that Tracker's BPoseView was (accidentally?) using what used to
be _BWidthBuffer_. It had declared it's own class with the same name and
same members/size in headers/private/tracker/TextViewSupport.h, but the
implementation was nowhere to be found. I can only explain this that
the BTextView implementation was then actually linked and used. But the big
problem was that it was used without locking (unlike in BTextView)! When
many Tracker windows opened during system startup or later and they happened
to each request characters not yet in the cache, I imagine things could have
gone bad and corrupted memory. Anyways, since I can see the usefulness of
the cache, BPoseView uses BTextView::WidthBuffer on purpose now. And I moved
the locking inside BTextView::WidthBuffer::StringWidth().
* Adjusted InterfaceDefs.cpp accordingly.
* TODO: Move subsequent classes into BTextView namespace as well, ie derived
classes that BTextView doesn't directly know about. All stuff in src/kits/
inteface/textview_support/
* Added preliminary and not yet implemented layout friendly BTextView
constructors.
* I will try to handle the insets imposed by BTextView::fTextRect a bit
differently when used inside the new layout management framework. For this,
I added BTextView::SetInsets() and GetInsets(). SetInsets() doesn't do
anything yet.
So far, everything seems to work still... ;-)

* We can't enable interrupts in an interrupt handler. Instead we use the
newly introduced callback feature, which notifies the debugger right
before returning from the interrupt.
* We didn't indicate that the profiling buffer was full and that the
thread shouldn't be profiled ATM. Therefore it could happen that it
was profiled while trying to notify the debugger that the profiling
buffer was full, resulting in a deadlock. Introduce a respective flag
in the thread debug structure.

be tracked to the kernel, which then counts the hits, an area is
passed to kernel in which the hits are recorded. When the area is
full, the debugger is notified. For some reason that part doesn't work
yet -- the whole system freezes when waiting for a reply.
* Reorganized the profile tool code a bit. For one with respect to the
changed API, but also to prepare tracking of image creation/deletion.

doing a lot of these things the same way as BMenuField are already doing.
Perhaps a private helper class could be refactored from these two controls
to avoid duplicating a lot of this code, although there are a few subtle
differences here and there.
These changes make a BTextControl behave properly in the layout management
frame work, in case CreateLabelLayoutItem() and CreateTextViewLayoutItem()
are _not_ used to layout the BTextControl.

* Got rid of fSkipSetFlags member by simply calling the BView::SetFlags()
directly where fSkipSetFlags was supposed to prevent the custom

* Used B_FOLLOW_ALL for the child text input, it should be more correct.

times as many. Might work better on real hardware.

* Introduced init_thread_debug_info() which is used instead of
clear_thread_debug_info() when the thread is created. The latter
requires former initialization.
* user_debug_thread_deleted() is now already invoked in thread_exit(),
not in the undertaker.

* The most important fix is that in BMenuField::_ValidateLayoutData(),
divider was calculated, but then never used. If the menu field was not
using the layout management, it should take the existing fDivider into
account, but never did. This caused #2728.
* Added some tracing that helped me debug this.
* Fixed a bunch of layouting inconsistencies. It will also improve some
unnecessary resizing of the menu bar.
Will test all of this some more. But in the test app I do have, the BMenuField
works more like in BeOS now.
