a reference to a by them not yet referenced cache was not correct.
They only incremented the reference count, but a vnode cache reference
includes also a vnode reference. In case of the page daemon this would
cause vnode references to be lost (causing bug #1465).
* The page daemon used an unsafe method to access a yet unreferenced
page cache. There was nothing that prevented the cache from being
deleted while the page daemon tried to get a reference. The
vm_page::cache field is now protected by the page cache table
spinlock, too, which the new function
vm_cache_acquire_page_cache_ref(), used by the page daemon, also
acquires while trying to get the reference.

* Added an "orphaned" flag to the process_group structure and code to

* Handle the death of a controlling process correctly: The
foreground process group gets a SIGHUP and all newly-orphaned process
groups containing at least one stopped processes are sent
SIGHUP+SIGCONT.

* The tty handles reads/writes from processes from other sessions

* The vm_translation_map is now correctly held in all of the vm_ mapping
functions.
* Removed the old vm_daemons.c file - there is now a new vm_daemons.cpp
which contains the beginnings of our new page daemon.
So far, it's pretty static and not much tested. What it currently does
is to rescan all pages in the system with a two-handed clock algorithm
and push pages into the modified and inactive lists.
* These inactive pages aren't really stolen yet, even though their mappings
are removed (ie. their next access will cause a page fault). This should
slow down Haiku a bit more, great, huh? :-)
* The page daemon currently only runs on low memory situations, though.

DEBUG_CACHE_LIST) that prints an unspectacular list of pointers to all
existing caches. Feel free to extend.
* Enhanced MultiAddressSpaceLocker:
- It supports choosing between read and write lock per address space,
now.
- Added AddAreaCacheAndLock(), which adds the address spaces of all
areas that are attached to a given area's cache, locks them, and
locks the cache. It makes sure that the area list didn't change in
the meantime and optionally also that all areas have their
no_cache_change flags cleared.
* Changed vm_copy_on_write_area() to take a cache instead of an area,
requiring it to be locked and all address spaces of affected areas to
be read-locked, plus all areas' no_cache_change flags to be cleared.
Callers simply use MultiAddressSpaceLocker:: AddAreaCacheAndLock() to
do that. This resolves an open TODO, that the areas' base, size, and
protection fields were accessed without their address spaces being
locked.
* vm_copy_area() does now always insert a cache for the target area. Not
doing that would cause source and target area being attached to
the same cache in case the target protection was read-only. This
would make them behave like cloned areas, which would lead to trouble
when one of the areas would be changed to writable later.
* Fixed the !writable -> writable case in vm_set_area_protection(). It
would simply change the protection of all mapped pages for this area,
including ones from lower caches, thus causing later writes to the
area to be seen by areas that shouldn't see them. This fixes a problem
with software breakpoints in gdb. They could cause other programs to
be dropped into the debugger.
* resize_area() uses MultiAddressSpaceLocker::AddAreaCacheAndLock() now,
too, and could be compacted quite a bit.

Condition variables would never be interrupted.
* ConditionVariableEntry::Add() did not correctly insert the entry into
the per-thread list of entries (the next link of the previous entry
was not adjusted), which could leave the entry unnotified when the
previous entry was notified, thus leaving it in the respective
condition variable's list after the end of its life time. This should
fix a crashing bug I rarely encountered.
* Added debug checks in the PrivateConditionVariableEntry
constructor/destructor that should have helped me to find
forementioned bug hours earlier, had I been bright enough to realize
that I didn't include <debug.h> and those KDEBUG guarded checks were
never executed. :-/

is used instead of death_entry for team::dead_children.
* Added team::{stopped,continued}_children, which, analoguously to
dead_children, are used to track the state of stopped/continued
children.
* A team does have a job_control_entry, which is allocated at team
creation time. It will be inserted into the parent's
{stopped,continued}_children lists as the team's main thread is
stopped/continued and removed when waitpid() retrieves the child
state. When the team dies the entry is detached from the team and goes
into the parent's dead_children list.
* Removed the wait_for_any field from team_dead_children. It was solely
used to avoid deletion of the contained entries in certain situations.
wait_for_child() (the waitpid() backend) always deletes an entry now,
regardless of whether other threads are waiting; that's in
accordance with the waidpid() specification. wait_for_thread() removes
the entry only, if the caller is the parent of the respective team.
* Introduced team_set_job_control_state() which performes the job
control entry transitions between the respective lists and wakes up
threads waiting in wait_for_child(). It is invoked on team death and
when the team's main thread receives job control signals.
* Reorganized wait_for_child(). It handles WCONTINUED and WUNTRACED now,
too. Removed a block that interpreted the supplied ID as thread ID.
* Added missing parts in waitpid().
Job control starts to work, though it seems to have some glitches.

* It is now possible for a thread to wait for more than one condition

* get_signal_stack() checked the wrong sig_action field (index is signal-1), also,
it had an off-by-one error in the stack range check.
* factored out a restart_syscall() function to avoid code duplication
* arch_setup_signal_frame() relied on the fact that vregs and the signal stack code
is a multiple of 4 bytes in size.
* Fixed sigaction(): it did return the error code directly instead of setting errno.
* signal() actually had a work-around for the broken sigaction()...
* Replaced the sig_func_t typedef with a sighandler_t typedef - this is non-standard
anyway, but now we're at least compatible with the GNU world instead of introducing
our own solution (BSD seems to use sig_t here, BTW).
* Removed now unused sigval structure from the header; it should be added again as
soon as we start supporting it.
* SA_RESETHAND and SA_ONESHOT are the same thing; the former did not work before.
* Made the non-standard SA_* flags refer to the standard ones instead of the other
way around.
* Added a test application for various signal features - works fine under Haiku,
tested also under Linux and BeOS (the latter fails as it does not support SA_RESTART).
More tests should be added, though.

* Added helper classes for locking the address space: AddressSpace{Read|Write}Locker,
and MultiAddressSpaceLocker which can lock several spaces at once and makes
sure no dead locks can happen.
* resize_area() is now using the MultiAddressSpaceLocker instead of no locking
at all; ie. it should now be safely to use.

It handles the locking for getting the font cache entries.
It works by giving it a template class GlyphConsumer which does the

it was only there to account for some peculiarities of the node monitor which

* NotificationListener no longer includes a doubly linked list link for convenience;
it might want to listen to more than just one service.
* NotificationService cannot have an abstract destructor.
* Changed the _user_stop_watching() syscall to mirror the Be API; ie. it's no
longer possible to just remove some flags separately, just to stop listening
completely.
* Adapted the node monitor implementation to live in the NodeMonitorService class
that uses the new notification framework.
* Removed the public kernel node monitor API - it wasn't useful that way since you
couldn't do a lot with the KMessage in the kernel without using a private API.
Now you will have to use the (private) notification manager to use the node monitor
from inside the kernel. At a later point, we might introduce a public API for that,
too.

* More conditional debug code (wrt page transitions between caches).
* Replaced debugger command cache_chain by a nicer cache_tree.
* While handling a soft fault: When we temporarily unlock a cache, it
can theoretically become busy. One such occurrence is now handled
properly, two more panic() ATM, though should be fixed.
* When merging caches, we do now always replace a dummy page in the
upper cache, not only when the concurrent page fault is a read fault.
This prevents a page from the lower (to be discarded) cache from still
remaining mapped (causing a panic).
* When merging caches and replacing a dummy page, we were trying to
remove the dummy page from the wrong cache (causing a panic).
The Haiku kernel seems now to run shockingly stable. ATM, we have more
than two hours uptime of a system booted and running over network. We
didn't manage to get it down by fully building Pe, downloading, unzipping,
and playing with various stuff. Someone should finally fix all those app
server drawing bugs, though (hint, hint! ;-)).

I "ported" the region implementation from XOrg to work on BRegion data.
This resulted in pretty much the same code structure as before, with
RegionSupport.cpp containing the messy details. Only now it _is_ really messy
from a code beauty point of view. I didn't exactly feel like cleaning it
up right now... but I guess I will have to.
So what does this mean - our BRegion implementation was very slow (no offense!),
and on top of that it scaled very badly with more and more rects. The new
implementation seems to be on par with the very fast R5 implementation and
the data looks exactly the same too. BRegion is very performance critical
for the app_server, and I cannot wait to try this on my slow computer...
Some changes are noteworthy: The right and bottom coordinates of
BRegion internal data are now exclusive! I inherited that from the
XOrg implementation and didn't feel like changing the code, seeing it
is probably tested quite well. The conversion is handled transparently.
Secondly, constructing a BRegion with just one rect is not invoking
malloc anymore for the member data, this makes it much more efficient
to use temporary BRegions with just one rect, both externally and internally
in the BRegion implementation.

stack hungry and would previously hit the stack limit and thus cause a
double fault. Hopefully we'll be able to reduce the stack foot print at
some time.

* Images preloaded by the boot loader had to be modules to be of any use
to the kernel. Extended the mechanism so that any images not accepted
by the module code would later be tried to be added as drivers by the
devfs. This is a little hacky ATM, since the devfs manages the drivers
using a hash map keyed by the drivers inode ID, which those drivers
obviously don't have.
* The devfs emulates read_pages() using read(), if the device driver
doesn't implement the former (all old-style drivers), thus making it
possible to BFS, which uses the file cache which in turn requires
read_pages(), on the device. write_pages() emulation is still missing.
* Replaced the kernel_args::boot_disk structure by a KMessage, which can
more flexibly be extended and deals more gracefully with
arbitrarily-size data. The disk_identifier structure still exists,
though. It is added as message field in cases where needed (non net
boot). Moved the boot_drive_number field of the bios_ia32 platform
specific args into the message.
* Made the stage 1 PXE boot loader superfluous. Moved the relevant
initialization code into the stage 2 loader, which can now be loaded
directly via PXE.
* The PXE boot loader does now download a boot tgz archive via TFTP. It
does no longer use the RemoteDisk protocol (it could actually be
removed from the boot loader). It also parses the DHCP options in the
DHCPACK packet provided by PXE and extracts the root path to be
mounted by the kernel.
* Reorganized the boot volume search in the kernel (vfs_boot.cpp) and
added support for network boot. In this case the net stack is
initialized and the network interface the boot loader used is brought
up and configured. Since NBD and RemoteDisk are our only options for
net boot (and those aren't really configurable dynamically) ATM, the
the boot device is found automatically by the disk device manager.
Booting via PXE does work to some degree now. The most grievous problem
is that loading certain drivers or kernel modules (or related activity)
causes a reboot (likely a triple fault, though one wonders where our
double fault handler is on vacation). Namely the keyboard and mouse input
server add-ons need to be deactivated as well as the media server.
A smaller problem is the net server, which apparently tries to
(re-)configure the network interface we're using to boot, which
obviously doesn't work out that well. So, if all this stuff is disabled
Haiku does fully boot, when using the RemoteDisk protocol (not being
able to use keyboard or mouse doesn't make this a particular fascinating
experience, though ;-)). I had no luck with NBD -- it seemed to have
protocol problems with the servers I tried.

* Reworked the internal layout. _ValidateLayoutData() computes and caches the
layout related data and all other methods just use those values. Now, in
layout-aware mode the class should properly work not only when using the
layout items. And when using layout items, the class does actually do
internal layout; it was basically good luck that it worked in the tests,
before. Vertical resizing is supported, too.
* We do a few mean tricks to get the probably mostly preferred layout behavior:
By default our own explicit max width and that of the menu bar layout item is
set to unlimited and the horizontal menu bar alignment to left aligned. This
allows to horizontally resize a BMenuField beyond its preferred size,
although both label and menu bar have a limited max width. The user can, of
course, override those explicit sizes/alignments to get a different behavior,
if desired.
* Fixed invalidation in SetDivider(). When having the focus, the left and top
border of the blue frame were not invalidated.
* The label is no longer drawn at vertical position font ascent + descent
+ leading + 2 (not sure how this calculation was supposed to work), but
vertically centers the label around the ascent. With big fonts the label is
shown a bit too far to the bottom. Not sure how to fix this in a generic way.

the maximum width. The latter supports unlimited maximum width. The
_BMCMenuBar_ draws fine when resized wider than its min/preferred width, but
not the complete "button" area will cause the menu to open when being pressed.

discussed in the thread in haiku-development. I added a fSubmenus member

despite being talked about repeatedly, does not currently exist.
Adding this required adding some new Jam rules to deal with this shared source
directory and headers. I had some fun figuring this out. Despite writing
articles about Jam in the Haiku newsletter a few years ago I still find Jam to
be a PITA at times.
But my solution seems to work pretty well. Basically you just call the rule
UseSharedSource and pass the name of the shared source file you want to use.
This rule sets up the header directories and the right Jam variables for the
source file. You then add the source file to the source list in the Application
rule like any other source file.
I also made the authors list sent to the about window constructor null
terminated instead of passing the size of the array, as suggested by Hugo.

realized that calling it a window may not be strictly correct since it isn't a
decendent of BWindow, but just uses a BAlert. Oh well, it can be changed if
need be.
I'm also checking in the first use of it, in ShowImage. Since ShowImage can
still be compiled for R5 I've added a #ifdef around the new BAboutWindow
related code.
I'm open for suggestions for the interface for this class, well mostly the
constructor. I'm not a big fan of having to specify the number of authors.
For now I'm making the header private, but I don't think it would be a big deal
to expose it publically.

only invokes the BView version. Didn't know what to do with MinSize() and
PreferredSize(). ATM they return fixed, hard-coded values. It might make
sense to compute something depending on the font size, for instance.

and DoLayout(). When the B_SUPPORTS_LAYOUT view flag is set (as is by
default when using one of the new constructors) the BBox completely manages
one true child (the first child that is not the label view).
* Centralized the layout related computation in new method
_ValidateLayoutData(). The computed infos are cached in a new private
LayoutData structure.
* GetPreferredSize() was broken in several respects. It does now return the
same result as PreferredSize(). If B_SUPPORTS_LAYOUT is not set, these are
the sums of the insets induces by the frame and the label. I.e. those values
can for instance be added to the child's preferred size to compute the
preferred size of the compound.
Not sure, if the Haiku-only TopBorderOffset() and InnerFrame() functions still
make sense. With layout management they're actually superfluous.

disjunction of all view flags before, and the new layout related flags were
missing. I suppose there was not striking reason for previous method.
* Made InvalidateLayout() virtual. When implementing layout management
directly in a derived class instead of a separate BLayout, one needs to
override it to know when to discard cashed layout infos.
* Added a ResizeTo(BSize) method.
* Avoided ugly multi-line strings in PrintToStream().

BMenuWindow. BMenuScroller now is just the scroller button, and it's a
child of BMenuWindow. This simplifies attaching/detaching the
scrollers, and it's also a bit cleaner.
The lower scroller wasn't shown anymore for some reason, and this commit also fixes this problem.
A drawing bug shows up now, though: when scrolling the menu UP, some
spurious lines are drawn over the menu. I wonder if this is an
app_server bug or what.
