This is an implementation of pthread barriers pursuant to the relevant specification.
Barriers are essentially a special case of conditional variables,
such that all threads waiting on one are woken up when the number of
waiters reaches a number provided at the initialization of the barrier.
In view of that, this implementation mimics the implementation of pthread_cond,
except it is more specialized and self-contained.

It is used by the media kit, which created a dependency from libmedia to
libbnetapi to openssl.
It is not entirely specific to the network kit, there are some use cases
that don't involve network at all.
* Fixes problems with setting the partition name after uninitializing
a partition in DriveSetup. Previously, UninitializeJob() was
followed by SetStringJob(), but the kernel was updating the
change counter for the parent partition when uninitializing a
partition, leading to SetStringJob() having an incorrect change
counter for the parent partition. Now the parent change counter
will be correct when SetStringJob() runs.
* Also defer signals while registering fork hooks.
* While malloc provides fork heap hooks which lock the heaps and unlock/reinit,
malloc_debug provides empty hooks.
* Ideas suggested by Ingo, patch reviewed by him. Thanks a lot!
* Also call fork parent hooks on failure.
* Solve locks-up when combining multithreading and process forking, should help
with #13111.
* There's no need to supply ways to mismatch the buffer duration
and size. Anything should reflect the media_format, this is at least
fixed on API level.
* There's no point actually in providing BTimeSource dependant
functionality. If and when there will be need for something like
that, possibly never, an higher level solution will be integrated.
Revert "repo rework: Remove stubs; Breaks repo compat."
Revert "repo rework: Remove need for repos to be self-aware"
This reverts commit a2b2f4d642.
This reverts commit 602076ef82.
This reverts commit 5ffaf72c8a.
These changes break the build on Haiku and the ability to create repo
mirrors, for the lack of a replacement for the URL (an UUID was evoked
on the mailing lists, but not implemented).
We are due for a release soon, please don't break the build.
Team:
- Adjust report generation event to include a final status code for listeners.
CliContext,TeamWindow,ReportUserinterface:
- Use aforementioned status code to indicate whether report generation
succeeded or failed.
DebugReportGenerator:
- Notify listeners if report generation fails. This may have previously
been responsible for some bug reports where it was indicated that the
debugger hung without exiting after being asked to save a report from
a crashed app.
- When dumping disassembly, retrieve it directly if necessary rather than
requesting it via the user interface listener. This also fixes the quirk
that requesting to save a crash report while looking at the source code
of a function would trigger switching it to disassembly visually.
- When walking the list of threads to dump, acquire references to all of
them before starting. Otherwise, it was potentially possible for a running
but not crashed thread to exit while we were generating the report, leaving
us with a pointer to a deleted thread. This was most likely the cause of one
of the crashes reported in #13082.
- When receiving the notification that source code state has changed, clear
the waiting function. Otherwise, it was potentially possible for us to get
other state change notifications, leading to the data semaphore being
released too often. This would then cause later potential waits such as
the stack frame memory dump to not actually wait when they should,
potentially leading them to dereference objects that weren't yet ready.
This fixes another of the crashes in #13802.
* These stubbs satisfied older Haiku releases that
required the URL
* Users running nightly images will need to upgrade
to hrev50723 - hrev50744 before upgrading further
* Getting this out of the way now before the beta
comes out.
* New installations shouldn't suffer any problems.
- Split MessageCodes.h into a second file that separates out the
application-specific message codes from those used by the core.
Adjust includes accordingly. No functional change.
Apple has gotten around to updating their POSIX support so these
constants are now defined. Add some #ifndef guards to prevent warnings
during compile.
* See #12917 for details.
* Squashed to one commit to make revert easy if we
run into any issues.
* pkgman is now pre-attached to the 'current' repo
version within nightly images so they can be updated
by default.
* This shouldn't impact us keeping older sets of package
versions by commit hash for building older hrevs.
* There are XXX stubs with "Kill me". These will need
to be dropped after users are given sufficent time to
upgrade. We're dropping a previously required field (url)
so making this a slowish roll out.
* Makes the repos a lot less restrictive which should
help PM package building automation be a bit easier.
* Once this stuff smooths out, we'll add UUID's to the
repo definitions for duplicate repo detection.
* The idea is to move the callback based mechanism into a derived
class. The objects can be composed to create working systems.
* The BMediaClient class supply RegisterInput/RegisterOutput
and BeginInput/BeginOutput is moved to BSimpleMediaClient.
* Various minor fixes.
* Capabilities() become Kind()
* Use media_client and media_connection to better model
the different situations of the API. Reduce code duplication
and move media_kit structs/methods into private.
* Various API and beauty improvements.
* Introduce id management for media_connections.
* Fix different issues preventing to correctly begin a connection.
* Those structs are provided as replacement for the classic
media_kit ones. They provide better encapsulation of the data
and the resulting code is heavily simplified. It's planned to
introduce BMediaRoster functions to provide conversion from
media_node and media_input/media_output to media_client
and media_connection.
FunctionInstance:
- Add new state FUNCTION_SOURCE_SUPPRESSED. This signals that the user
explicitly forced disassembly to be loaded despite source code being
available.
LoadSourceCodeJob:
- When forced to disassembly, use the above suppressed state accordingly.
SourceView/TeamWindow/TeamDebugger:
- Adjust to take new state into account as needed.
TeamDebugInfo::GetActiveSourceCode:
- When looking at a function to decide whether to return line information
based on source or disassembly, first examine the source code state. If
the source has never been loaded for that function, but we have it available,
set it on the function at that point. This lazily addresses the fact that
LoadSourceCodeJob is called on behalf of a specific function, and
consequently only sets the source code onto that function, and not all others
present in the same file. This allows us to differentiate between the case
where a function doesn't have source code available at all, versus a function
that has simply been forced to disassembly view at this point in time.
The primary symptom of the above issue was that attempting to set a breakpoint
outside of the currently active function, but within the same file would result
in the breakpoints view indicating that the breakpoint was at line 0 rather
than the appropriate line, and breakpoints would also not be drawn in the
source view for such locations.
Thanks to Humdinger for the heads up!
Chunks may be physically contiguous, but virtually disjoint. Adding
physical addresses may cause ranges to be merged incorrectly.

* The BMediaClient is an higher level API to the media_kit. It
corresponds to what the layout API was for the interface_kit.
The main idea is to allow the developer concentrate only on
higher level details and avoiding handle with the tricky parts
of the media_kit. At the same time the general purpose node that
is implemented inside would allow implementing the best techniques
around thus at the same time reducing code duplication and increasing
efficiency.
* BMediaClient is WIP, this is the initial merge of the branch.
The initial development stone was set long time ago and walked
through various design/implementation phases.
- Various cleanups to the USB-audio side, which is similar
- Add in the UVC (USB Video) specific info with parsing of some of the
descriptors (most of the "control" part).
* Ideally we should support this feature by default to allow
future improvements to the plugins management.
* Fixes the major memory corruption that lead to various
crashes on exit in MediaPlayer.
This makes it possible for the Asynchronous listener to get the
messages. It can then process them in a more fancy way.
The default implementation will still log the messages to the console
(if debug is enabled), but it will do so from the Async listener for
asynchronous requests now. This means they will probably be logged from
the same thread, and show up in a more readable way.
This also makes it possible to listen to several requests and log them
in a nice way (in a status window or whatever).
- Remove uses of group matching regular expression, not available on all
build hosts,
- Parsing is faster than our old regexp engine.

- Fixes#13002
- Fixed some indentation (tabs vs space), please configure your editor
properly.
* beaglebone vs beagleboard
* While the boards are almost the same, they have
diff. FDT's now (more memory, different layout etc)
* Make u-boot script more rpi-like
(depend on u-boot for initial addresses)
* Wasn't working, still doesn't.
* Remove enqueue_time again.
* Lateness seems generally useless. No way to get something useful
experimentally. The commit noise however was useful, the port wait is
behaving more in accordance with the lateness calculus.
* Fixes#12817 and possibly #12594.
* Now pulling in latest amdgpu atombios.h headers
* Lots of DisplayPort cleanup and removal of legacy stuff
* Add obsolete atombios header for things that disappear
(amdgpu doesn't support older cards like we do)
* Introduce new code to support later encoder tables
* Drop radeon-specific encoder service from common dp_info
* Tested on HD 5450 hdmi
* Helps prevent mainboard explosions and other bad stuff.
* ...maybe not explosions, but bad things.
* The RX 480 reference design can pull as much as 90W
from its PCIe slot at load. PCIe is rated for 75W.
* This change overloads the PCIe power cables vs the PCIe
slot. The PCIe power cables can handle going over spec.
* Untested since we really can't come close to loading a
RX 480 without hardware OpenGL ^_^
* Should be able to test on real hardware within a week.
As usual we ask ICU to do the actual work. The TextEncoding constructor
is fed with a sample of the text to identify (ICU docs recommend a few
hundred bytes). The text is analyzed in various ways (bytes patterns
such as UTF-8 escaping schemes, common letter sequences from known
languages, byte order marks) and an encoding is determined.
Replace code in StyledEdit by this new implementation.
Note that ICU seems to always return some valid encoding, even with fed
with obviously non-text data. This makes StyledEdit open the files no
matter what, where it would error out before.
Fixes#9395.
- Add new interface TeamFunctionSourceInformation. Currently this
exposes a single function allowing one to query for the currently
active source code given a FunctionDebugInfo instance.
- Implement TeamFunctionSourceInformation on TeamDebugInfo.
- Pass TeamFunctionSourceInformation to Dwarf{Team,Image}DebugInfo.
In turn, make use of it in DwarfImageDebugInfo::GetStatement() in
order to determine whether to return the corresponding assembly
or source statement.
With this piece of information, the debugger is now correctly able to
determine that the user is currently looking at disassembly despite debug
info being available, and consequently adjust its stepping behavior based on
that. Previously, the source code statement was always used, leading to it
not being possible to single step assembly lines in such a circumstance
without manually using run to cursor.
Other related cleanups:
- TeamDebugInfo now inherits BReferenceable directly, rather than relying on
indirectly inheriting it from TeamTypeInformation.
- Remove BReferenceable from TeamTypeInformation. The latter is only an
interface anyways, and inheriting that base class from multiple locations
was causing GCC5 trouble when resolving BReference<TeamDebugInfo>, even
when virtual inheritance was used.
The HashMap constructor was called before the heap is initialized,
ending up calling malloc from the OpenHashMap constructor.
Oddly it was still working on x86 but broke other platforms.
Instead we add a Lookup() static method to Partition,
which by default walks gPartitions for the id,
and recursively calls itself on the children lists.
This means we must add a partition even temporarily to gPartitions
before Scan()ing it though.

There was some mixup with the interrupt registers, still:
- The driver uses 16-bit read/write, but on SandyBridge the register is
32 bits
- There is a global interrupt enable bit, which must be set to unmask
everything else
- The bits for vblank interrupt are not the same on SNB and later PCH
based devices, and the code mixed the two.
Move the computation of the interrupt bits to an helper function, and
use it everywhere to make sure we always use the right bits.
Modesetting
===========
My previous hack was setting the transcoder registers, instead of the
display ones. Do that the way it is designed in the driver instead:
- If there is a transcoder, set its registers, but do not set the
display timings. The display will remain set at its native (and only)
resolution, and panel fitting will adjust the output of the transcoder
to match.
- If there is no transcoder, set the display registers directly to the
native resolution, as it was done on previous generation devices.
- fPipeOffset hacks no longer needed
DPMS
====
It seems the panel control register is not readable on PCH? Anyway, the
code would loop forever waiting for the bit to become unset when turning
the display off. Waiting seems to not be needed, so just remove it as
well as the "unlock" bit, which does not work for me and results in a
black screen.
Remaining hacks
===============
I still need to force HEAD_MODE_A_ANALOG to get output on pipe B (LVDS
display) working. I suspect something is common to the two pipes or not
allocated to the right one.
This version will have less side effects on other generations and help
with getting things to work on SandyBridge and possibly later devices.
Please test and report.
BeOS had a feature where you could click on a list and while holding
down the mouse button scroll through the list items selecting them
as you went. I implemented the same feature on Haiku.
Did the work in separate thread which makes sure that the mouse
is held down the whole time even if you leave the view.
Thanks Diver for bringing this feature to my attention.
* Rename kDoubleClickTresh to kDoubleClickThreshold
and use floating point in rval
* Pointer (*) goes with type for property var
* Use {}'s for multi-line if conditional
* rename point to where (consistent with header and rest of IK)
* Explicitly compare with 0 for bitwise operator statements
* Rename InitiateDrag() params
- This is how it is named in other versions of elf.h (Linux, glibc, possibly more)
- ELF_MAGIC is used by libelf for the same thing, and the defines conflicts,
breaking libelf build on Haiku.
Add an Icon() and SetIcon() method. Override SetMarked() to set the
parent menu field icon.
Don't move the label right if icon is NULL. Make the first menu item
an IconMenuItem with a NULL icon. This allows the icon to draw in the
closed menu state.
icon gets updated even if you select an item in a submenu

* Make the color box a rectangle with proportions of golden ratio.
* Override GetContentSize() to make menu item area larger.
* Label should never truncate since I make sure there is enough room.
* Draw the label using BMenuItem parent class
* Carefully adjust the spacing so that there is an attractive amount of
padding between the checkmark and color box and the color box and label.
Add _AddMenu method to BMenuField that adds BColorMenuItem as its
base menu item. This shows the BColorMenuItem in the closed state.
Create BPrivate::MenuItemPrivate
Add a SetSubmenu() method to MenuItemPrivate that gives you
the ability to add a submenu after creating the object. This
method should be public
Skip disabled items
Color gets updated even if you select an item in a submenu
Architecture:
- Store and provide accessor for the size in bytes of the low-level
debug_cpu_state size of the respective target CPU. Adjust subclasses
to pass in the appropriate size information.
The only file in here was Deskbar.h, which just included the "real"
Deskbar.h. Considering nothing in-tree cares about this, and only
a small number of applications at HaikuArchives do, and that Haiku already
broke BeOS source compatibility in lots of other ways, let's just remove
this deprecated cruft.
