apps using that library (like Gobe Productive) from running.
It now calls the Haiku equivalent _kern_lock_node(), and Gobe now runs fine!
This closes bug #562.

this fixes bug #1423, the loop interface removed the default route for the
other interface (didn't happen previously, as routes were bound to devices).

* Removed weird spaces, fixed indentation.

I am going to search for the cause next, but at least app_server
dosn't crash anymore in this context. Left a comment on my findings
so far.

* added a Query menu to the main menu, giving access to some
email queries
I refactored the patch a little and added monitoring the query folder,
so that all open Mail windows should update. However, I might not have
got it to work as intended, at least I got no entries for the query results,
even though the same query did return results when run in Tracker.
This should implement the idea in #1208, and that's also where the patch
was attached.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22702 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Rewrote TextView.h
* Renamed all private methods to have the underscore prefix.
And also:
* Whitespace and line width cleanup.

The low memory handler now has two passes which should help there; however, it
might also accidently remove recently used vnodes, too. We could mark the clean
ones in some way if that turns out to be a problem.

BufferQueue::Add() tried to remove a negative amount of bytes. This could
bring a download to a complete halt (as could the other one due to the list
link mixup).
* While the RTT computation still seems to work not that good (with a drop quote
of 50% I would easily reach retransmit timeouts of 80 secs), TCP should now
work a lot better on a flaky connection.
* Renamed _GetMSS() to _MaxSegmentSize().
* Minor cleanup.

1) Some video modes which did not work properly with the Savage chips
have been removed from the mode list, and a few wide-screen modes which
work have been added.
2) The code which loads the cursor image has been simplified. This code
is similar to the code I'm using in the S3 Virge video driver which I
will be submitting to the Haiku project in a few days. This change also
removes the last piece of code that came from Erdi Chen's BeSavage
driver; thus, this diff file also removes his copyright from the file
savage_cursor.c.
I did a minor modification to fix a warning in ProposeDisplayMode.c (it
now includes savage.h). Thanks!
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22670 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added a way to initialize built-in dependencies that the tcp_shell is now
using - at least it gets to the prompt again (it still doesn't work, though).
* Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22669 a95241bf-73f2-0310-859d-f6bbb57e9c96
* add filtering of files by mimetype when adding them to the playlist
* some changes by myself (added Axel's suggestion to guess the mimetype
in order to support other filesystems than BFS)
Fredrik -> please have a look at our coding guidelines, also you have weird
whitespaces in your patches... :-)

We will fake hardcoded devices depending on the platform.
Hopefully that will help some generic drivers (ide) to work without major modification.
Synced to r22648.

* Got rid of the PARAMS_AS_STRING stuff (it's always defined, anyway).
* Will remove BeOS support, too, in the future.
* Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22644 a95241bf-73f2-0310-859d-f6bbb57e9c96
This should help to reduce the number of warnings imported code will throw
during compilation (helps a lot with tcpdump, for example).
* Since long is 64 bit on 64 bit platforms, we might want to think about doing
that change for the Haiku types int32 and uint32 as well.
* Fixed several occurences of hidden type problems.
* Fixed build of the stack and TCP under BeOS.
* Fixed incorrect typedef in socket_interface.h.
* Minor cleanup.

* Named settings are only overwritten if they were an exact match (ie. it's
the very same monitor).
* The unnamed settings retrieval now has two passes, on the first it will
now ignore named settings. It will also only remove unnamed settings now.
* Added some TODO commments.

a while ago that removed the incorrect automatic addition of Haiku header
directories in case of targets other than "haiku". The app server test
environment does now almost build again. The problem left is related to the
recent changes of the accelerant interface. I suppose someone in the knows
should decide if we can simply use our header or if special handling is
needed.

just the frequency.
* Previously saved modes are no longer supported, though.
* Screen modes are now stored with the monitor info it belongs to, IOW the
app_server will now choose a mode from the settings that fit your monitor
description. Driver support is required for this to work as intended.
* The changes are completely untested at this point, though, sorry (shouldn't
harm anyone, though) :-)

status checker now only tries to lock the manager, it won't wait anymore.
* Added MediaChanged() and UpdateMediaStatusIfNeeded() methods to KDiskDevice.
* KDiskDeviceManager::_CheckMediaStatus() now uses these new methods; it should
no longer detect removed media more than once :-)

DiskDeviceJobQueue.
* Basic synchronous implementation of BDiskDevice::CommitModifications(),
ignoring the given parameters, though.
* Some more work on DiskDeviceJobGenerator: Added class
PartitionReference which will reference a partition while the jobs are
executed. The generator manages the mapping of partitions to those
references now. Also exemplarily implemented the generation of the
InitializeJob.
* Moved support functionality to private header DiskDeviceUtils.h.

through our revisions, I found r20883 to be the cause of this problem.
This one obviously fixed bug #1185, but I'm afraid there has to be another
solution for this problem.

* in r22410 the unlock/relock was removed accidently from ServerWindow::_Hide()
before calling a desktop method.
* Desktop::ActivateWindow() no longer calls SetWorkspace() with the window lock
held.
* WorkspacesLayer::MouseUp() now uses the asynchronous version of SetWorkspace().
* AFAICT AS_HIDE_WINDOW, AS_SHOW_WINDOW, and AS_MINIMIZE_WINDOW don't need the
all window lock, reverted to standard single window lock.

current state of the disk device into the desired one. Most code was
taken and adapted from the soon to be gone kernel class
KDiskDeviceJobGenerator. The methods creating the job objects are only
stubs ATM.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22611 a95241bf-73f2-0310-859d-f6bbb57e9c96

delegate, thus reflecting the hierarchy as it was before changes.

the userland. Depending on how we want the API user to interface with
it, we may want to reintroduce a similar class later.
* Cleared remaining references to shadow partitions.

{Prepare,Commit,Cancel}Modifications() using the userland add-on
backend. IsModified() and CommitModifications() are little more than
stubs ATM.
* Made BPartition::VisitEachChild()/VisitEachDescendant() const.

BDiskSystem to BPartition and reimplemented them using the userland
add-on backend instead of syscalls. As a side effect this solves the
TODO I recently added in GetNextSupportedType().
* Reimplemented BDiskSystem::GetTypeForContentType() using the userland
add-on backend instead of a syscall.
* Moved GetTypeForContentType() and IsSubSystemFor() from
BPartitionHandle to BDiskSystemAddOn. They were misplaced.

API, and opinions are welcome.

note: i think it should be enough to only call _kern_set_tzfilename(..) as the timezone offset and
dst would have been set by clockconfig on boot or from the time prefs panel while switching the
timezone. so the comment in _user_set_tzfilename should not be count and no update would
be needed. it should only take the sIsGmt boolean take into account when getting the time.

implemented; it now only returns wether or not the window is part of the
list specified by the index. This fixes bug #195 and #1553.
* HasInSubset() would report "true" for app-floating windows vs. modal app
windows which was wrong.
* Removed SameSubset() as it isn't needed at all.
* SubsetWorkspaces() now take the front window into account for floating
windows.
* Minor cleanup.

collection of no-op methods, which could as well be implemented in
BPartition itself. This makes the Delegate hierarchy unnecessary:
MutableDelegate becomes Delegate, and we save a few casts as a side
effect.

* Removed IOC bit on last TD. To find out whether the TD removed is the
last one of a transfer it simply iterate through every transfer submitted. Not the best
solution, but should be ok for now. Improvements will be made when there will be some driver to test it with.
* Clean up

builds the object hierarchy, the second will (in case of MutableDelegate)
let the disk systems do their initialization. This way the disk systems
already find a fully functional object hierarchy they can work with.
* Child creation also takes a partition name as a parameter, now.
* Implemented BMutablePartition child creation/deletion.
* The BDiskSystemAddOn/BPartitionHandle::Validate*() methods return a
status_t instead of a bool, now.

Summer of Code project. Thanks for your work Łukasz and I hope we can see
more work from you.
Still to do:
- Create an icon.
- Add pkg files to the MIME database with PackageInstaller as the default
handler. The rdef here has the MIME type name for the pkg format should
anyone else choose to add it :)
- Support for running scripts included with packages.
- Testing various different packages.
- Fixing problems in the Haiku GUI layout system which affect the code used
for various parts of the installer GUI (please bear with the commented out
code for now.)
- Adding this to the image.
Tomorrow I will add Łukasz's InstalledPackages utility which can be used to
view installed packages and uninstall them.

* Renaming, fixing coding guidelines
* Re-writing AddTo method
* Removing ohci_software.h file (its content has been moved to ohci.h) but it will probably be deleted in the future.

the accelerant, as well as its EDID info. B_GET_PREFERRED_DISPLAY_MODE and
B_GET_EDID_INFO are both optional. The preferred mode will be taken from the
EDID info if only the latter hook is implemented, or the former returned an
error.
* Currently, the app_server should correctly set the preferred mode on start,
but no accelerant supports that yet, so it's not really tested.

to create their mode list. Once it's done, it should cover all possible cases,
and allow the base mode list to reside in the app_server (under Haiku, at least),
so that all drivers will benefit from an updated list.
Right now, it might already work to a degree, but it's not yet tested.

not work; it would always choose the last thread of the current priority.
IOW a thread was never skipped, and lower priority threads were never called
when a higher priority thread was running - from the POV of the scheduler,
we only has real time threads...

* Minor cleanup.

* Removed old port test code, it doesn't belong there.
* Cleanup.

vm_page_reserve_pages() and vm_page_allocate_page() will now steal pages from
the inactive queue as needed.
* We currently never steal active pages anymore, but this might need to be
revised later (therefore, the page scanner never waits anymore, but uses
mutex_trylock() to lock a cache).
* The page scanner and writer now both run at normal priority - let's see how
that will work out.
* Introduced an inactive queue.
* Instead of shuffling pages around in the queue (and therefore destroying LRU)
the page stealing mechanism now uses a marker page to be able to release the
page lock without losing its position in the queue.
* The page writer now always grabs the whole release count of the semaphore, so
that there won't be a huge backlog to catch up with.
* vm_page_num_free_pages() now also includes the inactive queue as well as the
reserved pages (they are no longer regarded as free pages).
* Added a insert_page_after() function that inserts a page after another one,
needed by the marker code.
* clear_page() now gets a vm_page instead of a physical address which simplified
some code.
* Removed superfluous initialization of the queues (if those aren't zeroed on
start, we would have serious problems, anyway).
* Removed old and unimplemented dump_free_page_table() ("free_pages") KDL
command.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22506 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Fixed warnings with debug output turned on.
* Shuffled functions around a bit.
* Minor cleanup.

vm_remove_all_page_mappings() all computed the wrong virtual address for the
page in question, and would therefore return incorrect data!
Introduced a virtual_page_address() function that is now used by all of them.
So that's why we were still "losing" modified flags - it took me some hours
to find those (sometimes processes died after stealing pages)...
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22498 a95241bf-73f2-0310-859d-f6bbb57e9c96
it intended to. That resulted in more writable pages where you wouldn't want
them (ie. allowing the area to change pages in lower caches).
* We were losing modified pages: vm_unmap_pages() sometimes has to preserve
the modified flag (eg. when called from page fault).
* Both of these were responsible that stealing active pages would crash
applications - even if less likely, this could also have happened when
stealing inactive pages. Therefore, I've activated stealing active pages
again.
* The page writer now pushes the pages of busy vnodes to the end of the queue,
so that it won't pick them up again too soon (the vnode destruction would
be in the process of writing those pages back, anyway).

active pages. This might be a bit too aggressive, though.

* The page_thief() will no longer steal any pages in B_LOW_MEMORY_NOTE state,
only in the more serious cases.
* I've disabled stealing active pages for now again; there seem to be some
problems with it (either with how we do it, or with other stuff).
* vm_page_schedule_write_page() now always releases the page writer semaphore,
resulting in many more written pages - this isn't optimal as long as there is
no I/O scheduler, but before it was much too rare when there are many dirty
pages.
* Customized the thread priorities a bit to make the page scanner/thief/writer
experience a bit nicer with our current scheduler.
* vm_page_reserve_pages() would return too early, it did not test if really
enough pages are free.
* Under certain circumstances, the wakeup from vm_page_reserve_pages() did not
work - we now always notify in vm_page_unreserve_pages() to work around that
problem.
* Checked if the page reservations are done when needed and are always balanced
for the whole kernel.
* vm_page_allocate_page() now panics if it can't deliver a reserved page.
* vm_page_allocate_page_run() can no longer steal reserved pages.
* With all of those changes, I could finally copy a file in emulation, ie. the
Luposian bug should finally be fixed, even though the system might still not
be perfectly stable under low memory. Will do some more testing.
* write_page() no longer prints something on failure.
* Dumping a whole page queue will now also write the cache type of each page.

busy vnodes.
* dir_create_entry_ref() used get_vnode() incorrectly (and could therefore
potentially prevent a file system from doing proper locking when called
from the kernel).
* The vnode_store now uses this for its acquire_unreferenced_ref()
implementation (and therefore for the page writer).
* read_into_cache() and write_to_cache() were still marked inline.
* The system will now wait 10 secs for a busy vnode before returning an error.
* It will also no longer panic in that case.

additional partition_data* child parameter now.
* _user_get_partitionable_spaces() doesn't need to copy the buffer into
the kernel, since it is no input parameter. It also copies back the
actual partitionable spaces count on error, now -- B_BUFFER_OVERFLOW
is returned when the buffer was too small, but then the count must be
returned too.
* Fixed several instances of syscall implementations that unloaded a disk
system, although they didn't load it in the first place. This screwed
up the load count with undesirable consequences.
* _user_create_child_partition() would set the size to the supplied
offset.
* Fixed broken loop in KPhysicalPartition::CreateShadowPartition().
* KPartition::RemoveChild() notified the listeners about the wrong
event.
* Intel partitioning module:
- The *_get_partitionable_spaces() correctly return B_BUFFER_OVERFLOW
now, if the supplied buffer is too small.
- Implemented a part of pm_shadow_changed(), which creates and updates
the PartitionMap, so that the validate_*() hooks have a chance to
work at all.

allocate with the vm_cache locked - this is necessary to be able to steal pages
from itself (large files...).
The system doesn't actually lock up anymore, but it still renders itself unusable;
obviously the page thief does not work correctly, yet. The rest of the experience
is created by our current scheduler (the page thief runs and runs, but it doesn't
free any pages anymore).

twice into the same cache: cache_io() called read_into_cache() (or
write_to_cache()), and that broke down the request into smaller parts.
It then called read_chunk_into_cache() (or write_chunk_to_cache() resp.)
to actually allocate pages and fulfill the request.
However, it needed to unlock the cache for each chunk, and in the mean
time someone else could insert pages into the remaining chunks.
* Now, cache_io() already takes care of chunking the data which makes this
approach safe, and also simplified the code a bit - read_into_cache()/
write_to_cache() are gone now. I've renamed read_chunk_into_cache() to
read_into_cache() (same for the write function).
* Also got rid of that goto in that function while I was on it.
* Disabled cache_prefetch_vnode() for now (it's similar to cache_io(), but
since it's currently not used [since no cache module is installed yet],
I didn't want to go through updating it now, too).

interfere with the page thief, we always need to have reserved a page for
this upfront. I introduced a function to the vm_translation_map layer that
estimates how much pages a mapping might need at maximum. All functions that
map a page now call this and reserve the needed pages upfront.
It might not be a nice solution, but it works.
* The page thief could run into a panic when trying to call vm_cache_release_ref()
on a non-existing (NULL) cache.
* Also, it will now ignore wired active pages.
* There is still a race condition between the page writer and the vnode
destruction - writing a page back needs a valid vnode, but that might just
have been deleted.

no longer necessary.
* intel partitioning system:
- Removed passing around block sizes. We require 512 byte sectors
anyway. In fact using the parent partition's block size was even
wrong.
- Simplified writing the partition map sector.
- Simplified and corrected the partition map initialization.
- We don't fail identifying a partition anymore, if the partition map
contains no partitions. We would never identify a freshly
initialized partition map before.
- Made pm_identify() more intelligent: It determines the priority to
return depending on whether the partition is the device itself and
whether we have recognized child partitions.

of locking before processing the message (single/all window lock)
-> in most message cases, I could comment out the unlocking/locking which
switched to the different lock, because the required lock is now already held,
this removes some race conditions which were commented in the code already
* EventDispatcher::SetDragMessage() didn't lock the object, this would have
been bad if multiple windows tried to set a drag bitmap at once
* the Desktop object keeps track of mouse position and pressed buttons, so
that it doesn't need to lock the EventDispatcher for sending fake mouse
moves to windows on show/hide of windows (solves some cases of possible
dead locks with the new locking strategy)
* the keyboard EventFilter switches the current workspace asynchrnously from
the Desktop thread (another source of possible deadlocks)
* the "reader is trying to become writer" check in MultiLocker is only used
in DEBUG mode now
As a summary: It would be nice if ServerWindow used a readlock for all messages
it processes itself, and forwards all messages for which it needs a write lock
to the Desktop thread. All cases where either the Desktop or the ServerWindow
mess with the EventDispatcher are possible sources of deadlocks. This is solved
right now by making sure that the lock is released before using the
EventDispatcher.
I have not observed any deadlocks while switching workspaces and launching
many apps anymore, neither crashes. But I have not tested extensively except
for in the test environment. That being said, I could reproduce the problems

* Reworked the select support:
- The io_context additionally stores a table of lists of select_infos,
which enables it to deselect events of a pending select() when
closing a FD. This prevents a race condition potentially causing a
write to stale memory.
- The opaque selectsync* passed to FSs is now actually a select_info*.
This was necessary, since the FDs deselect() hook (unlike the
select() hook) doesn't take a "ref" argument and deselecting a
single info (e.g. caused by a premature close()) was not possible.
The select() hook's "ref" argument has become superfluous.
- It should now be relatively easy to implement a poll_on_steroids()
that can also wait for objects other than FDs (e.g. semaphores,
ports, threads etc.).
* Set/reset the signal mask in common_select(). This makes pselect()

necessary because low memory handlers might need to wait for other services
while we need to make sure the page thief can always steal pages.
* Made the page thief more aggressive when memory is critical: added a third
run where it will also steal a small amount of active pages to keep things
going.
* The page thief did not maintain the cache's reference correctly in all
situations.

account when checking for the number of readable bytes. For readers
it doesn't make a difference, since they were looping anyway, but
select() would report read-availability incorrectly.

writers.
* Removed the optimization for piping data between two threads of the
same team. This greatly simplifies the code. It seems to me the case
is very uncommon; it could be added back later, though.
* Basically rewrote reading from and writing to the pipe:
- A blockable writer can now write more than what is currently
available in the ring buffer.
- Writing respects the PIPE_BUF non-interleaving limit, though our
headers don't seem to define PIPE_BUF anywhere.
- Unblock writers, when the last reader is gone and send those that
haven't written anything yet a SIGPIPE. Fixes bug #1476.
* Correctly implemented select() support. We were only notifying
writers. We manage two separate select sync pools per pipe now: one
for the reader end and one for the writer end.
* Reading/writing from the root dir does no longer end in KDL.

Added support for non-48-bit LBA, added write support.
Proper error handling still missing, write support disabled for your protection.

components - now, we divide the initialization of that service into two parts
which allows this (before, most handlers were gone after boot).
* Added debugger command that dumps the low memory handlers.
* The slab allocator now registers its low memory handler with a higher
priority, so that it'll run before the potentially heavier ones.
