* Wait evaluation is done considering both position
and buffer size.
* Set back position to 0 after seeking.
* Simplify EvaluatePosition to take advantage of inheritance.
* Use back position to determine the current size of the buffer.
* Add more debug tracing.
* Other minor fixes.
* Implement Open/Close mechanism.
* Implement SetBuffer.
* Implement timeout handling.
* Improve Seek mechanism, this is now working by locking the
thread until the backend call SeekCompleted.
* Moved data locking in the internal buffer class, includes handling
of backend writes.
* Takes advantage of inheritance for getting the size. The choice is
made depending on the flags. This allow the implementer to easily
return a custom size by reimplementing GetSize. At the same time
a plain BAdapterIO can still have it's total size set, but the behavior
will change depending it's mutable or not.
* Some decisions are now made by considering everything in absolute
values.
* Other minor fixes.
* This is by default provided using a relative buffer. When the
client request a seek over the range we currently have, we will
ask the backend with a SeekRequested. When the backend operation
ended successfully, the client is required to call SeekCompleted
before to return. This will cause the offset to change and the
buffer is cleaned as result. Next data received will be considered
to be at a position equal to the offset plus the relative position.
- Add subfolder src/kits/debugger which contains the debugger's core
functionality and lower layers. Correspondingly add headers/private/debugger
for shared headers to be used by clients such as the Debugger application
and eventual remote_debug_server. Adjust various files to account for
differences as a result of the split and moves.
- Add libdebugger.so to minimal Jamfile.
* This class is provided as a safe multithreaded communication channel
between a BMediaIO-like interface and a Read/Write backend.
* Includes internal buffering and can be used to provide multithreaded
edit of the data.
* Current limitations include missing BOutputAdapter and
correct timeout handling.
* Future plans provide a BRemoteAdapterIO that using ports
and areas allow to easily send big data between processes.
- Messages that expect a reply are now tagged with a unique ID field to
indicate that expectation to the receiving socket messenger.
- The messenger now maintains a map of received reply IDs and their
corresponding messages, along with a message queue of other unsolicited
replies.
- After successfully connecting, the messenger now spawns a thread
whose sole responsibility is receiving and parsing all incoming messages,
and consequently sorting them into the aforementioned data structures based
on the presence of the reply ID. Callers who are awaiting either replies or
other messages are signalled appropriately via a semaphore. This allows
multiplexing of both types of messages on the same socket.
- Introduces new network API class BSocketMessenger, allowing one to send
and receive BMessages across a network socket in a BMessenger-like
fashion. Still very much WIP, hence currently not exposed via public headers.
Based partly on previous work by Axel.
* Add function core_dump_write_core_file(). It writes a core file for
the current thread's team. The file format is similar to that of
other OSs (i.e. ELF with PT_LOAD segments and a PT_NOTE segment), but
most of the notes are Haiku specific (infos for team, areas, images,
threads). More data will probably need to be added.
* Add team flag TEAM_FLAG_DUMP_CORE, thread flag
THREAD_FLAGS_TRAP_FOR_CORE_DUMP, and Team property coreDumpCondition,
a condition variable available while a core dump is progress. A
thread that finds its flag THREAD_FLAGS_TRAP_FOR_CORE_DUMP set before
exiting the kernel to userland calls core_dump_trap_thread(), which
blocks on the condition variable until the core dump has finished. We
need the team's threads to stop so we can get their CPU state (and
have a generally unchanging team state while writing the core file).
* Add user debugger message B_DEBUG_WRITE_CORE_FILE. It causes
core_dump_write_core_file() to be called for the team.
* Dumping core as an immediate effect of a terminal signal has not been
implemented yet, but that should be fairly straight forward.
Similar to arch_get_debug_cpu_state(), but the thread whose CPU state
to retrieve is specified. Works only for threads that aren't running,
and on x86-64 we can get the FPU state only when the thread was
interrupted in userland.
Not implemented for the incomplete architecture ports.
This resolves a TODO: We used thread_interrupt() to wake up the thread
from an interruptable wait. However, if the thread was already in the
kernel and about to start waiting, that would have no effect and the
thread would wait anyway. Now there's the new non-blockable signal
SIGNAL_DEBUG_THREAD, which is sent to the thread instead, making sure
that thread doesn't start waiting.
* New Intel SkyLake seems to have 9 mapped ranges
at boot. It seems like this define has been creeping
up for a while.
* Resolves the inital issue reported in #11377 on SkyLake
as well. Bonefish mentioned it might need to be raised
again... he had some good foresight there :-)
* I'm seeing the same no bootable partitions issue though
via USB after this raise. (maybe a USB 3.1 thing?)
* When the user isn't requesting a custom notification, it will
be a BMediaRoster job to do it.
* Reintroduce BMediaRoster::SyncToServices, this time based on local
message passing rather than a global semaphore.
* SyncToServices is used in launch_media_server to make the process
more launch_daemon safe and faster in the average case.
* It was an error to add notifications in the media_server.
* Fixes#12717.
...to just DefaultSettingsView
It is just as obvious what it does in context, but shorter.
Rename the function it contains from
BuildDefaultScreenSaverSettingsView to
BuildDefaultSettingsView
* The old debug system was too complex and made
troubleshooring difficult. (it also was unique
like a snowflake... which we don't want)
* Move to the classic TRACE / ERROR a large majority
of the code has changed to.
* I like trace statements, but drop some obvious ones
* Fix style issues along the way
* Remove SyncToServices, I will probably readd it in future
but this time using a local synchronization service more than
relying on the media_server to release the semaphore.
* Due to some discussions today in mailing list I decided
to step back and retry the initial way to notify media rosters
about media services status. It is woking by using two different
notifications for reconnecting to the media_server and notifying
the local subscribers.
* This speed up the media services restart.
* Sorry for the noise and very thanks for reviewing my code to
everyone.
* The global synchro semaphore is provided with the purpose of
being used to avoid threads lock up when the media_server is in
an undefined state. There's still room for improvements.
* BMediaRoster::SyncToServices lock up on a semaphore until
the multi_audio correctly connected to the mixer.
* There's no need to force the streamer plugin to use a
BMediaIO. This class is supplied to accomodate more smart uses,
but in certain cases it makes just things more complex. If a
plugin doesn't need to have an internal caching method, then it
will be simpler to implement a block-consuming BDataIO and let
the internal BMediaIOWrapper to deal with caching.
* When a watched directory contains a mount point, we need to resolve
the actual parent directory of the mount point in the file system to
serve the monitor.
* Added a directory argument for notify_{stat/attribute}_changed().
* This allows to watch only a directory, and get the notifications for
all of its files, not just add/remove entry notifications.
* Move current_mode into the accelerant as the
driver doesn't care.
* Record panel_mode in driver and present to accelerant
* eDP, if no EDID and mobile, leave edid incomplete.
Mode set should notice that and fall back to panel_mode
