This allows the loader to skip BFS partitions that don't contain
a bootable system. Useful when you have a BFS data partition that
comes before the system partition when iterated over.
Currently, only the UEFI loader actually returns more than one
possible partition.
BFont::Blocks is now implemented in ServerFont, via a call through the
app_server. It uses fontconfig to iterate through a charset of a font
and stores the defined blocks in a bitmap.
A new API was added, BFont::IncludesBlock, that will allow for arbitrary
testing of a given Unicode block. Since nothing is cached, searching
through an entire charset for a series of Unicode blocks can be quite
slow. In a given block there may be only 1 or 2 characters actually
defined so every character within a block needs to be checked until one
is found, which in a degenerate case will mean the entire block is
checked.

* This allows KPath to not allocate a buffer when initialized
without path.
* Added test cases for this.
* Added test for LockBuffer().
* Enhanced tests to allow building them in debug mode.
* Moved calling vfs_normalize_path() into own private method.
* Improved error codes; B_NO_MEMORY is now only returned if the
allocation actually failed.
* If used with LAZY_ALLOC, Path() and LockBuffer() are now allowed
to return a NULL path.
When both Backgrounds and Screen are open, if the workspace color is changed
in Backgrounds the monitor preview in Screen will now refresh to the new color.
Also added a BAlert in BackgroundsView.cpp when failing to change the
background image.

Fixes#13286.
* It's very important to use a negative value to identify
non valid or uninitialized connections. Additionally, it's preferred
to don't interfere with media_kit types as long as the framework use
it in the backend.
* Add special handling for reading the BEOS:TYPE attribute to supply
on-the-fly fake MIME types for FUSE module filesystems, the same
way it's done in our FAT and NTFS FS modules
* Reuse the mime_ext_table which we already have and put it into a
shared location so we don't get further extra copies of it
* Add a way for a FUSE module to supply Haiku-specific extensions.
This allows it to integrate better with Haiku while only requiring
minimal changes on the FUSE module itself.
* For now, there is only one extension: another function pointer for
"get_fs_info", which lets the FUSE module fill in an fs_info struct.
FUSE provides no good way to otherwise communicate extra information,
such as the volume flags (e.g. B_FS_IS_SHARED).
* A FUSE module can signal that it supports the Haiku extensions by
a) defining HAS_HAIKU_FUSE_EXTENSIONS before including the fuse
headers
b) setting the global variable gHasHaikuFuseExtensions to 1 in
its initialization
Otherwise, the Haiku extensions are completely invisible to the
FUSE module.
Update all in-tree consumers of the BJson API to match. Also added
const-qualifiers to the BString versions of the API, and added the leading
"_" to the header guards.
... reverse this to avoid confusion, you'll see why in next commit.
No functional change intended in this commit, functional change is in the
next commit.
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.

* 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.
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.
- 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.
* 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.
